       AES   undertakes  no   obligation  to  publicly   update  or  revise  any

                                  THE COMPANY


       AES is a global power  company  committed to serving the world's need for
electricity in a socially responsible way.

       AES has been  successful  in growing its business and serving  additional
customers by, in part,  participating in competitive bidding under privatization
initiatives.   AES  has  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.  AES  believes  that its  experience  in  competitive  markets and its
worldwide integrated group structure,  with its significant  geographic coverage
and  presence,  enable it to react quickly and  creatively in these  situations.
Since 1994, AES' total net generating capacity in megawatts or MW has grown from
2,479 MW to 28,986 MW at June 30, 1999 (an  increase of 1,069%),  with the total
number of plants in operation increasing from 9 to 98. Additionally,  AES' total
revenues  have  increased  at a  compound  annual  growth  rate of 46% from $533
million in 1994 to $2,398  million in 1998,  while net income has increased at a
compound  annual  growth rate of 33% from $100  million to $311 million over the
same period.

       AES'  ownership   portfolio  of  power  facilities  includes  new  plants
constructed for such purposes,  so-called greenfield plants, as well as existing
power plants acquired through  competitively bid  privatization  initiatives and
negotiated  acquisitions.  In the electricity  generation business, AES now owns
and operates  (entirely or in part) a diverse portfolio of electric power plants
(including those within integrated  distribution companies) with, as of June 30,
1999,  net  capacity  of 28,986  MW. Of that  total,  42% are  fueled by coal or
petroleum coke, 25% are fueled by natural gas, 28% are hydroelectric  facilities
and 5% are fueled by oil. A majority  of AES' 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
usually  made  under  long-term  contracts  from  power  plants  owned  by  AES'
subsidiaries and affiliates,  although it does, in certain  circumstances,  make
sales into regional electricity markets without contracts.


                              RECENT DEVELOPMENTS


       AES' recent  activities  evidence its  accelerated  pace of acquiring and
developing assets and businesses.  Importantly, AES' activity has been worldwide
and diversified over  generation,  transmission,  distribution,  and competitive
retail services. For example:

       AES  announced  on August 18, 1999 that one of its  subsidiaries  reached
agreement with National Power plc for the acquisition of the Drax Power Station,
Ltd.  ("Drax") for 1.875 billion pounds  (approximately  $3 billion).  Drax is a
3,960 MW coal  fired  power  station  complete  with  flue gas  desulphurisation
located on an 1800 acre site in northern England. AES believes it is the largest
coal-fired  plant  in  western  Europe  and  generates  approximately  8% of the
electricity  consumed in England and Wales. The acquisition of Drax will provide
a foundation upon which AES intends to build its European franchise.  Completion
of the  transaction is subject to a number of conditions,  including the receipt
of certain regulatory approvals and the approval of the shareholders of National
Power. Closing is expected to occur later this year.

       AES announced on November 23, 1998, a definitive agreement to acquire all
of  CILCORP's  13,610,680  common  shares  at a  price  of  $65  per  share,  or
approximately  $885 million.  CILCORP is an integrated  electric and gas utility
based in  central  Illinois  that  combines  two  coal-fired  generation  plants
producing an aggregate  1,157 MW of capacity and an extensive  transmission  and
distribution  network that serves 193,000 electricity  customers and 203,000 gas
customers.


                                      S-3
<PAGE>

On August 20, 1999, AES received from the Securities and Exchange  Commission an
exemption to the Public  Utilities  Holding Company Act of 1935,  enabling it to
purchase CILCORP,  while maintaining its existing ownership levels in the United
States power  plants  developed  under the  auspices of the 1978 Public  Utility
Regulatory  Policy  Act.  CILCORP  represents  AES' first  investment  in a U.S.
distribution  company.  AES plans to close the CILCORP  acquisition early in the
fourth quarter of 1999.

       In May 1999, AES completed the  acquisition of six  coal-fired,  electric
generating  plants from NGE Generation,  a subsidiary of Energy East,  Inc., for
approximately  $950 million.  The output of these plants is currently  sold into
the merchant power market.

       On August 10, 1999, AES announced the acquisition of 51% of Eletronet,  a
Brazilian telecommunications company which owns and operates approximately 5,000
kilometers  of dark fiber optic cable  attached  to Brazil's  national  electric
network,  for  approximately  $155  million.  Eletronet  was  created in 1998 to
construct  a  national  broadband  telecommunications  network  attached  to the
existing national  electrical  transmissions grid in Brazil. This purchase price
will be paid in installments  through 2002.  Eletronet plans to use the proceeds
of the sale of 51% of the company to expand this network to approximately 12,000
kilometers of fiber optic cable. The fiber optic cable is intended to be sold to
other  telecommunication  carriers.  The other 49% of Eletronet is controlled by
Lightpar,  a subsidiary of  state-controlled  Eletrobras.  This  investment will
leverage  into  the  telecommunications  sector  AES'  existing  operations  and
experience in the Brazilian utilities market.

       AES  announced  on May 18,  1999,  the  acquisition  of  energy  services
provider New Energy Ventures for  approximately  $90 million in cash,  stock and
debt. The new subsidiary, renamed NewEnergy, was purchased from UniSource Energy
and New Energy Holdings. It was formed in 1995 to serve customers in every state
where a competitive  energy  market is emerging.  This  technology-based  energy
company is active in markets  throughout the U.S.  NewEnergy's  services include
energy buying for customers,  energy efficiency  services and low-cost supply of
energy-related  equipment and supplies.  The acquisition of NewEnergy marks AES'
entrance into the energy retail marketing business.

       On August 24, 1999 AES announced  the  formation of Power  Direct,  a new
energy  services  subsidiary  that will  provide  electricity  and  natural  gas
services to retail  customers in the United  States.  Power  Direct's  principal
focus will be residential and small to mid-sized  commercial  energy users,  and
will complement NewEnergy's focus on larger commercial and industrial customers.

       AES announced on August 5, 1999 the completion of the  acquisition of 50%
of Empresa  Distribuidora de Electricidad del Este ("EDE Este") the distribution
company providing  electricity to approximately 400,000 customers in the eastern
portion of the Dominican Republic,  for approximately $109 million. AES believes
its investment in EDE Este complements its existing  investments in the Los Mina
generating facility.

       EDE Este was funded  through a $340 million bridge loan with a subsidiary
of AES, AES Texas Funding LLC (the "Texas Bridge").  The Texas Bridge is secured
by a pledge of 15.8 million  shares of AES common stock to the borrower.  One of
AES'  subsidiaries,  AES New York  Funding  LLC, is party to a $300 million loan
which is also secured by a pledge of 15.6 million shares of AES common stock. If
the lenders to AES Texas  Funding LLC or AES New York  Funding LLC  foreclose on
these  loans,  the lenders  would be entitled to register and sell the number of
shares of AES common  stock that would be required to repay these loans in full.
The  registration and sale of such shares in the public market would likely have
an adverse effect on the market price of AES common stock.

       None of the  financial  information  included  herein  reflects  or gives
effect to the pending  acquisitions  described above. AES cannot assure you that
these  acquisitions  will be consummated or will perform as expected or that the
returns from such  acquisitions  will support the  indebtedness it will incur to
acquire them.

                              SUMMARY INFORMATION
                             QUESTIONS AND ANSWERS


       The following information  supplements,  and should be read together with
the  other  information  contained  in  this  prospectus  supplement  and in the
accompanying prospectus.  This summary provides a brief overview of some aspects
of the Preferred  Securities.  You should carefully read the prospectus and this
prospectus  supplement  to understand  the terms of the Preferred  Securities as
well as the tax and other  considerations  that are  important  in  making  your
decision  about  whether to invest in the preferred  securities.  You should pay
special  attention  to the "Risk  Factors"  section  beginning  on page 5 of the
accompanying  prospectus  to determine  whether an  investment  in the Preferred
Securities is appropriate for you.


WHAT ARE THE PREFERRED SECURITIES?

       Each Preferred Security  represents an undivided  beneficial  interest in
the assets of AES Trust III (the "Trust").  Each Preferred Security will entitle
the  holder to  receive  cash  distributions  as  described  in this  prospectus
supplement. The Trust is offering the Preferred Securities at a price of $50 for
each Preferred Security.


WHO IS AES TRUST III?

       The Trust is a  Delaware  business  trust and a  subsidiary  of AES.  Its
principal place of business is c/o The AES Corporation,  1001 North 19th Street,
Arlington, Virginia 22209 and its telephone number is (703) 522-1315. All of the
common  securities  (the "Common  Securities"  and,  together with the Preferred
Securities,  the  "Trust  Securities")  of the  Trust  will be  owned by The AES
Corporation  ("AES" or the "Company").  The Trust will use the proceeds from the
sale of the Preferred  Securities  and the Common  Securities to buy a series of
junior subordinated  deferrable  interest  debentures (the "Junior  Subordinated
Debentures") from AES with the same financial terms as the Preferred Securities.


WHO IS THE AES CORPORATION?

       AES is a global power company,  with 98 power plants in operation,  87 of
which are located  outside of the United  States.  The  mailing  address of AES'
principal executive office is 1001 North 19th Street, Arlington,  Virginia 22209
and  our  telephone   number  is  (703)  522-1315.   AES'  Internet  address  is
http://www.aesc.com.  The  information on our website is not  incorporated  into
this prospectus supplement or the accompanying prospectus.


WHEN WILL YOU RECEIVE DISTRIBUTIONS ON THE PREFERRED SECURITIES?

       The  Trust's  only  source  of  cash to make  payments  on the  Preferred
Securities are payments on the Junior Subordinated  Debentures it purchases from
AES. If you  purchase  the  Preferred  Securities,  you are  entitled to receive
cumulative  cash  distributions  at an annual rate of $ per Preferred  Security,
accruing  from the date of original  issuance of the  Preferred  Securities  and
payable (except as described below) quarterly in arrears on
      ,      ,       and        of each year beginning on   , 2000.


WHEN WILL PAYMENT OF YOUR DISTRIBUTIONS BE DEFERRED?

       If AES defers interest  payments on the Junior  Subordinated  Debentures,
the Trust will defer  distributions  on the  Preferred  Securities  for up to 20
consecutive quarters.  During any deferral period, with certain exceptions,  AES
will not be permitted to:

       o     declare or pay a dividend or make any  distributions on its capital
             stock or redeem, purchase, acquire or make a liquidation payment on
             any of its capital stock or make any guarantee payments relating to
             the foregoing; or

       o     make an interest, principal or premium payment on, or repurchase or
             redeem any of its debt securities that rank equal with or junior to
             the Junior Subordinated Debentures.


WHEN CAN THE TRUST REDEEM THE PREFERRED SECURITIES?

       The  Trust  must  redeem  all  of the outstanding Trust Securities on   ,
2029. In addition, if AES redeems any Junior


                                      S-5
<PAGE>

Subordinated  Debentures  before their maturity,  the Trust will use the cash it
receives  from  the  redemption  to  redeem,  on a  pro  rata  basis,  Preferred
Securities and Common Securities having a combined  liquidation  amount equal to
the principal amount of the Junior Subordinated Debentures redeemed.

       AES can redeem some or all of the Junior  Subordinated  Debentures before
their  maturity  on one or more  occasions  in  whole  or in part at the  prices
specified  herein  at any time on or  after ,  2002,  and at any time at 100% of
their  principal  amount if certain  changes in tax law occur and certain  other
conditions are satisfied,  as more fully  described  under  "Description  of the
Preferred Securities--Special Event Redemption or Distribution."


WHAT IS AES' GUARANTEE OF THE PREFERRED SECURITIES?

       AES  has  irrevocably   guaranteed  that  if  a  payment  on  the  Junior
Subordinated  Debentures is made to the Trust but for any reason, the Trust does
not make the corresponding  distribution or redemption payment to the holders of
the  Preferred  Securities,  then AES will  make the  payments  directly  to the
holders of the Preferred Securities.  The guarantee does not cover payments when
the Trust  does not have  sufficient  funds to make  payments  on the  Preferred
Securities.  AES' obligations  under the guarantee are subordinated as described
on page 24 of the accompanying prospectus.


WHEN COULD THE JUNIOR SUBORDINATED DEBENTURES BE DISTRIBUTED TO YOU?

       AES has the right to dissolve  the Trust at any time.  If AES  terminates
the Trust,  the Trust will redeem the Preferred  Securities by distributing  the
Junior  Subordinated  Debentures to holders of the Preferred  Securities and the
Common Securities on a ratable basis. If the Junior Subordinated  Debentures are
distributed,  AES  will use it best  efforts  to list  the  Junior  Subordinated
Debentures on any exchange on which the Preferred Securities are then listed.


WILL THE PREFERRED SECURITIES BE LISTED ON A STOCK EXCHANGE?

       Application will be made to list the Preferred Securities on the NYSE. If
approved  for  listing,  the Trust  expects the  Preferred  Securities  to begin
trading  within 30 days after they are first issued.  The  Preferred  Securities
will trade under the symbol " ".


WILL HOLDERS OF THE PREFERRED SECURITIES HAVE ANY VOTING RIGHTS?

       Generally,  the  holders  of  the  Preferred Securities will not have any
voting rights. See "Description of the Preferred Securities."


IN WHAT FORM WILL THE PREFERRED SECURITIES BE ISSUED?

       The  Preferred  Securities  will be  represented  by one or  more  global
securities  that  will be  deposited  with  and  registered  in the  name of The
Depository Trust Company or its nominee.  This means that you will not receive a
certificate  for your  Preferred  Securities  and that your broker will maintain
your position in the Preferred Securities.

ISSUER....................  AES  Trust  III,  (the "Trust") a  Delaware business
                            trust.  The only assets of the Trust will consist of
                            the        %    Junior    Subordinated   Convertible
                            Debentures   due   2029  (the  "Junior  Subordinated
                            Debentures") of AES.

GUARANTOR.................  The AES Corporation, a Delaware corporation.

DISTRIBUTIONS.............  Your distributions on the Preferred Securities  will
                            will  accrue from      , 1999 and will be payable at
                            an  annual  rate  of  $      per Preferred Security.
                            Subject  to the deferral provisions described below,
                            distributions  will  be cumulative payable quarterly
                            in  arrears on      ,      , and       of each year,
                            commencing      , 2000. Because distributions on the
                            Preferred  Securities  are  considered  interest for
                            U.S.  federal income tax purposes, corporate holders
                             thereof    will    not    be    entitled    to    a
                             dividends-received deduction.

DISTRIBUTION DEFERRAL
PROVISIONS................. The ability of the Trust to pay distributions on the
                            Preferred  Securities depends only on the receipt of
                            interest   payments   from   AES   on   the   Junior
                            Subordinated  Debentures.  As long as AES  does  not
                            default  in the  payment of  interest  on the Junior
                            Subordinated Debentures,  AES has the right to defer
                            payments  of  interest  on the  Junior  Subordinated
                            Debentures by extending the interest  payment period
                            from  time  to  time  for   extension   periods  not
                            exceeding 20 consecutive  quarterly interest periods
                            (each, an "Extension Period"); provided that AES may
                            not extend the interest  payment  periods beyond the
                            maturity  of  the  Junior  Subordinated  Debentures.
                            Quarterly  distributions on the Preferred Securities
                            would be deferred by the Trust,  but would  continue
                            to accumulate  quarterly and accrue  interest  until
                            the  end of any  such  extension  period.  Upon  the
                            termination of an extension  period,  payment is due
                            on all  accrued  and  unpaid  amounts  on the Junior
                            Subordinated  Debentures.  Upon  such  payment,  the
                            Trust would be required to pay all  accumulated  and
                            unpaid  distributions.  If a deferral of an interest
                            payment   occurs,   the  holders  of  the  Preferred
                            Securities  will  continue to accrue income for U.S.
                            federal  income  tax  purposes  in  advance  of  any
                            corresponding cash distribution.

RIGHTS UPON DEFERRAL OF
 DISTRIBUTIONS............  During  any  period  in  which  interest payments on
                            the  Junior  Subordinated  Debentures  are deferred,
                            interest  will  accrue  on  the  Junior Subordinated
                             Debentures   and   quarterly   distributions   will
                            continue to accumulate with interest  thereon at the
                            distribution  rate,  compounded  quarterly.  AES has
                            agreed  not to declare  or pay any  dividend  on, or
                            redeem, purchase,  acquire or make a distribution or
                            liquidation payment with respect to its common stock
                            or preferred  stock or make any  guarantee  payments
                            with respect  thereto  during any Extension  Period.
                            The foregoing does not apply to any stock
                            dividends payable in AES common stock.

                            time  prior  to  the close of business on     , 2029
                            (or,  in the case of Preferred Securities called for
                            redemption,  prior  to  the close of business on the
                            Business  Day  (as  defined  herein)  prior  to  the
                            applicable  redemption  date)  at  the option of the
                            holder  into shares of AES common stock, at the rate
                            of        shares   of  AES  common  stock  for  each
                            Preferred   Security  (equivalent  to  a  conversion
                            price  of  $     per  share  of  AES  common stock),
                            subject  to adjustment in certain circumstances. The
                            reported  last sale price of AES common stock on the
                            NYSE  composite  tape  on  September  24,  1999  was
                            $63.625   per   share.   In   connection   with  any
                            conversion  of  a Preferred Security, the conversion
                            agent,  will exchange these Preferred Securities for
                            the  appropriate  principal  amount  of  the  Junior
                            Subordinated  Debentures  held  for  the  Trust  and
                            immediately   convert   these   Junior  Subordinated
                            Debentures  into  AES  common  stock.  No fractional
                            shares  of  AES  common  stock  will  be issued as a
                            result  of a conversion. Instead fractional interest
                             will be paid by AES in cash.

LIQUIDATION  AMOUNT.......  If  the  Trust  is  liquidated, you will be entitled
                            to  receive  $50  per  Preferred  Security  plus  an
                            amount    equal    to   any   accrued   and   unpaid
                            distributions   thereon  to  the  date  of  payment,
                            unless    Junior    Subordinated    Debentures   are
                            distributed to holders.

REDEMPTION................  The   Junior   Subordinated   Debentures   will   be
                            redeemable  for  cash, at the option of AES in whole
                            or  in  part,  from  time to time on or after      ,
                            2002  at  the prices specified herein or at any time
                            in  certain  circumstances  upon  the  occurrence of
                            certain  changes  in  tax  law at a redemption price
                            equal   to  100%  of  the  principal  amount  to  be
                            redeemed   plus  any  accrued  and  unpaid  interest
                            thereon,  including compounded interest, to the date
                            of  redemption.  If  AES redeems Junior Subordinated
                            Debentures,   the   Trust   must   redeem,   at  the
                            redemption   price,   trust   securities   having  a
                            liquidation  amount equal to the principal amount of
                            the  Junior Subordinated Debentures so redeemed. The
                            Preferred   Securities,   will  not  have  a  stated
                            maturity  date,  although  they  will  be subject to
                            mandatory  redemption  upon  the  repayment  of  the
                            Junior   Subordinated  Debentures  at  their  stated
                            maturity  (     ,  2029), upon acceleration, earlier
                            redemption or otherwise.

PREFERRED SECURITIES
GUARANTEE................ . AES will irrevocably and unconditionally  guarantee,
                            on a subordinated  basis and to the extent set forth
                            herein,  the  payment in full of (1) any accrued and
                            unpaid  distributions  and the amount  payable  upon
                            redemption of the Preferred Securities to the extent
                            AES has made a payment  to the  Property  Trustee of
                            interest  or  principal  on the Junior  Subordinated
                            Debentures and (2) generally, the liquidation amount
                            of the Preferred  Securities to the extent the Trust
                            has assets  available for distribution to holders of
                            Preferred   Securities.   The  preferred  securities
                            guarantee  will be unsecured and will be subordinate
                            and   junior  in  right  of  payment  to  all  other
                            liabilities of AES and will rank pari passu in right
                            of  payment  with the most  senior  preferred  stock
                            issued, from time to time, by AES.

VOTING  RIGHTS............  Generally,  holders   of  the  Preferred  Securities
                            will   not  have  any  voting  rights.  If  (1)  the
                            property  trustee  fails to enforce its rights under
                            the   Junior  Subordinated  Debentures  or  (2)  the
                            guarantee  trustee fails to enforce its rights under
                            the  Guarantee,  a  record  holder  of the Preferred
                            Securities   may   institute   a   legal  proceeding
                            directly   against   AES  to  enforce  these  rights
                            without   first  instituting  any  legal  proceeding
                            against  any other person or entity. Notwithstanding
                            the  foregoing,  if  an  event  of default under the
                            indenture  occurs and is continuing and is caused by
                            the  failure  of AES to pay interest or principal on
                            the   Junior  Subordinated  Debentures  or  AES  has
                            failed  to make a guarantee payment, a holder of the
                            Preferred   Securities   may  directly  institute  a
                            proceeding  against  AES  for  enforcement  of  that
                            payment.

SPECIAL EVENT DISTRIBUTION;
 TAX EVENT REDEMPTION.......Upon   the   occurrence   of   a  Special  Event, as
                            defined  in  this  prospectus  supplement, except in
                            certain  limited  circumstances,  AES  may cause the
                            Trust   to   be   dissolved  and  cause  the  Junior
                            Subordinated  Debentures  to  be  distributed to the
                            holders  of the Preferred Securities. In the case of
                            a   Tax   Event,   as  defined  in  this  prospectus
                            supplement,   AES   may  also  elect  to  cause  the
                            Preferred  Securities  to remain outstanding and pay
                            additional   interest,   if   any,   on  the  Junior
                            Subordinated  Debentures.  In  certain circumstances
                            upon  the  occurrence  of  a  Tax  Event, the Junior
                            Subordinated  Debentures  may  be redeemed by AES at
                            100%  of  the  principal amount thereof plus accrued
                            and unpaid interest thereon.

JUNIOR SUBORDINATED
 DEBENTURES OF AES..........The  Junior  Subordinated  Debentures will mature on
                               ,  2029  and  will  bear  interest at the rate of
                                % per annum,  payable  quarterly in arrears.  As
                            long  as AES is not in  default  with  its  interest
                            payments on the Junior Subordinated Debentures,  AES
                            has the right to defer  payments  of interest on the
                            Junior  Subordinated  Debentures  by  extending  the
                            interest  payment  period  from  time to time for an
                            Extension   Period  not  exceeding  20   consecutive
                            quarterly  interest  periods.  However,  no interest
                            period may be extended beyond the stated maturity of
                            the  Junior  Subordinated  Debentures.  Prior to the
                            termination of any Extension Period, AES may pay all
                            or a portion  of the  accrued  distributions  or may
                            further  defer  interest   payments,   provided  the
                            Extension   Period,   as   previously   and  further
                            extended,  does not exceed 20 consecutive  quarters.
                            During any Extension Period, no interest will become
                            due,  but  interest  will  continue  to  accrue  and
                            compound   quarterly.   Upon   termination   of  the
                            Extension Period,  payment is due on all accrued and
                            unpaid  amounts.  After the  payment of all  amounts
                            then due, AES may commence a new  Extension  Period,
                            subject to the conditions of this paragraph.  During
                            any Extension  Period,  AES will be prohibited  from
                            paying  dividends  on  any of its  common  stock  or
                            preferred  stock or making  any  guarantee  payments
                            with respect thereto;  provided, among other things,
                            that the foregoing shall not apply to any stock
                            dividends payable in common stock.

                            The payment of principal and interest on the Junior
                            Subordinated  Debentures  will  rank  junior to all
                            present and future  senior and senior  subordinated
                            debt of AES. In addition,  payment of principal and
                            interest on the Junior Subordinated Debentures will
                            be structurally  subordinated to the liabilities of
                            AES'  subsidiaries.  As of June 30,  1999,  AES had
                            $2,260  million  of senior  and  subordinated  debt
                            (which  includes $281 million of letters of credit)
                            outstanding.  In addition,  AES'  subsidiaries  had
                            debt  of  $5,363  million,   to  which  the  Junior
                            Subordinated     Debentures     are     effectively
                            subordinated.  The trust indenture, under which the
                            Junior Subordinated Debentures will be issued, does
                            not  limit  the  aggregate  amount  of  senior  and
                            subordinated  debt that may be  incurred by AES and
                            does not limit the liabilities of its subsidiaries.
                            The  Junior   Subordinated   Debentures  will  have
                            provisions  with  respect  to  interest,   optional
                            redemption and conversion into AES common stock and
                            certain other terms substantially  similar to those
                            of the Preferred Securities.

COMMON  STOCK  OFFERING...  Concurrently  with  this  offering,  AES  is selling
                            16,000,000  shares  of  its common stock in a common
                            stock   offering  (18,400,000  shares  assuming  the
                            underwriters'  overallotment  option  in  the common
                            stock   offering   is   exercised   in   full).  The
                            consummation  of  the  Preferred Securities offering
                            is  not  contingent  on  the  closing  of the common
                             stock offering.

                                USE OF PROCEEDS


       The proceeds to the Trust from this  offering are  estimated to be $300.0
million ($345.0 million if the underwriters'  overallotment  option is exercised
in full). We will invest the proceeds from the sale of the Preferred  Securities
in the junior  subordinated  debentures of AES. The net proceeds to AES from the
issuance of junior  subordinated  debentures  to the Trust are estimated to be $
million ($ million if the  underwriters'  overallotment  option is  exercised in
full).  AES  intends to use the net  proceeds  from the  issuance  of the junior
subordinated debentures (1) to fund a portion of the purchase price of Drax, (2)
unless we obtain a waiver,  to repay a portion of the $340 million  Texas Bridge
and (3) for general corporate purposes. Pending such uses, AES may use a portion
of the proceeds to  temporarily  repay amounts  outstanding  under its revolving
credit  agreement.  The revolver bears interest at a weighted  average  interest
rate of LIBOR plus 2% and matures in December  2000.  As of September  24, 1999,
amounts outstanding under the revolver were $122 million.

       AES is concurrently  offering  16,000,000 shares of its common stock. The
net proceeds  (before  expenses) from the common stock offering are estimated to
be $ million ($ million if the underwriters'  overallotment  option is exercised
in full). AES intends to use the net proceeds from the common stock offering (1)
to fund a portion of the purchase price of CILCORP, (2) to fund a portion of the
purchase  price of Drax,  (3) unless it obtains a waiver,  to repay a portion of
the $340 million Texas Bridge and (4) for general corporate purposes.

       AES expects to fund the  remainder  of the Drax and CILCORP  acquisitions
through a combination of  non-recourse  project  financing and  additional  debt
financing  by  AES.  None  of the  foregoing  sources  of  funds  is  committed.
Accordingly,  AES cannot  assure you that such sources or any other sources will
be available on favorable terms or at all.

       The  offerings  of  Preferred   Securities   and  common  stock  are  not
conditioned on each other or conditioned on the  consummation of the acquisition
of Drax or CILCORP and accordingly,  if these  acquisitions are not consummated,
AES will use the net  proceeds  that would have been used for such  acquisitions
for general corporate purposes.

       One of AES'  subsidiaries,  AES Texas  Funding  LLC, is party to the $340
million  Texas Bridge with an affiliate of Salomon  Smith Barney Inc.,  as agent
and a lender,  which is required  to be prepaid  out of the  proceeds of certain
debt and equity issuances by AES, including the issuance of Preferred Securities
in this offering and the  concurrent  issuance of common  stock.  AES may seek a
waiver of the prepayment  provision from the lenders under the Texas Bridge.  If
AES  does not  obtain  this  waiver,  it will  use all or a  portion  of the net
proceeds of this  offering to repay a portion of the amounts  outstanding  under
the Texas Bridge.  The Texas Bridge bears interest at a rate of LIBOR plus 2.75%
and  matures on March 6, 2000.  Borrowings  under the Texas  Bridge were used to
fund  the  purchase  price of EDE  Este,  a  portion  of the  purchase  price of
Eletronet and for general corporate purposes.

                     SELECTED CONSOLIDATED FINANCIAL DATA


       The following table summarizes  certain selected  consolidated  financial
data, which should be read in conjunction with consolidated financial statements
and related notes to the consolidated  financial  statements of AES incorporated
by reference in this prospectus supplement.  The selected consolidated financial
data as of and for each of the five years in the period ended  December 31, 1998
have been derived  from AES'  audited  consolidated  financial  statements.  The
selected  consolidated  financial data  presented  below as of June 30, 1998 and
1999 are derived from the unaudited  consolidated  financial  statements of AES.
The  results  of  operations  for the six  months  ended  June 30,  1999 are not
necessarily  indicative  of the  results to be  expected  for the full year.  We
believe that the  unaudited  information  for the six months ended June 30, 1998
and  1999  contain  all   adjustments,   consisting  only  of  normal  recurring
adjustments, necessary for a fair presentation of the operating results for such
periods.

       No cash  dividends  have been paid on the common stock since December 22,
1993.

       AES' ability to declare and pay  dividends,  if any, is dependent,  among
other things, on:

          o    the ability of AES' project  subsidiaries  to declare and
               pay dividends and otherwise distribute cash to AES;

          o    AES' ability to service parent company debt and

          o    AES'  ability  to  meet   certain   criteria  for  paying
               dividends  under its corporate  credit facility and under
               existing indentures of its debt securities.


                                 AES TRUST III


       AES Trust III is a statutory  business  trust formed on November 13, 1996
under the Delaware  Business Trust Act (the "Business  Trust Act") pursuant to a
declaration  of  trust  among  the  Trustees,  as  defined  in the  accompanying
prospectus,  and AES and the filing of a certificate of trust with the Secretary
of State of the State of Delaware. Such declaration will be amended and restated
in its entirety (as so amended and restated, the "Declaration") substantially in
the  form  filed as an  exhibit  to the  Registration  Statement  of which  this
prospectus  supplement and the  accompanying  prospectus  form a part, as of the
date the Preferred Securities are initially issued. The Declaration is qualified
under the Trust Indenture Act of 1939, as amended (the "Trust  Indenture  Act").
Upon issuance of the Preferred  Securities,  the holders thereof will own all of
the issued and outstanding Preferred Securities. The Company will acquire Common
Securities  in an amount equal to at least 3% of the total  capital of the Trust
and will own, directly or indirectly,  all of the issued and outstanding  Common
Securities. The Trust exists for the purpose of (1) issuing its Trust Securities
for cash and  investing the proceeds  thereof in an equivalent  amount of Junior
Subordinated  Debentures  and (2)  engaging  in  such  other  activities  as are
necessary,  convenient and incidental thereto.  The rights of the holders of the
Trust Securities,  including  economic rights,  rights to information and voting
rights,  are as set forth in the  Declaration,  the  Business  Trust Act and the
Trust Indenture Act. The Declaration does not permit the incurrence by the Trust
of any  indebtedness  for borrowed money or the making of any  investment  other
than in the Junior Subordinated Debentures.  In the Declaration,  AES has agreed
to pay for all debts and  obligations  (other  than  with  respect  to the Trust
Securities)  and all costs and  expenses  of the Trust,  including  the fees and
expenses of the Trustees  and any income  taxes,  duties and other  governmental
charges, and all costs and expenses with respect thereto, to which the Trust may
become subject, except for United States withholding taxes.

                    DESCRIPTION OF THE PREFERRED SECURITIES


       The  Preferred  Securities  will be issued  pursuant  to the terms of the
Declaration  which is  qualified  under the Trust  Indenture  Act.  The Property
Trustee , but not the other  Trustees  of the Trust,  will act as the  indenture
trustee for  purposes of the Trust  Indenture  Act.  The terms of the  Preferred
Securities and the Declaration include those stated in the Declaration and those
made part of the  Declaration by the Trust  Indenture Act and the Business Trust
Act. The following summarizes the material terms and provisions of the Preferred
Securities  and is qualified in its entirety by reference  to, the  Declaration,
which has been filed as an exhibit to the  Registration  Statement of which this
prospectus  supplement  forms a  part,  the  Business  Trust  Act and the  Trust
Indenture  Act.  Capitalized  terms  used  herein  without  definition  have the
meanings ascribed to them in the accompanying prospectus.


GENERAL

       The Declaration  authorizes the Trust to issue the Preferred  Securities,
which represent  preferred undivided  beneficial  interests in the assets of the
Trust, and the Common  Securities,  which represent common undivided  beneficial
interests  in the assets of the  Trust.  All of the  Common  Securities  will be
owned,  directly or indirectly,  by AES. The Common Securities and the Preferred
Securities rank pari passu with each other and will have equivalent terms except
that (1) if a Declaration Event of Default occurs and is continuing,  the rights
of the  holders of the  Common  Securities  to  payment  in respect of  periodic
Distributions  and  payments  upon  liquidation,  redemption  or  otherwise  are
subordinated  to the rights of the holders of the Preferred  Securities  and (2)
holders of Common  Securities  have the exclusive right (subject to the terms of
the  Declaration)  to  appoint,  remove or replace  Trustees  and to increase or
decrease the number of Trustees. The Declaration does not permit the issuance by
the Trust of any  securities or other  evidences of beneficial  ownership of, or
beneficial  interests in, the Trust other than the Preferred  Securities and the
Common Securities,  the incurrence of any indebtedness for borrowed money by the
Trust or the making of any  investment  other  than in the  Junior  Subordinated
Debentures.  Pursuant to the Declaration, the Property Trustee will own and hold
the  Junior  Subordinated  Debentures  as trust  assets  for the  benefit of the
holders of the Preferred  Securities and the Common  Securities.  The payment of
Distributions  out of  moneys  held by the  Property  Trustee  and  payments  on
redemption  of  the  Preferred  Securities  or  liquidation  of  the  Trust  are
guaranteed by AES on a subordinated  basis as and to the extent  described under
"Description  of  the  Guarantee"  herein  and  "Description  of  the  Preferred
Securities Guarantees" in the accompanying prospectus. The Property Trustee will
hold the  Preferred  Securities  Guarantee  for the  benefit  of  holders of the
Preferred  Securities.   The  Preferred  Securities  Guarantee  is  a  full  and
unconditional  guarantee from the time of issuance of the Preferred  Securities,
but the Preferred  Securities  Guarantee covers Distributions and other payments
on the  Preferred  Securities  only if and to the  extent  that  AES has  made a
payment  to the  Property  Trustee  of  interest  or  principal  on  the  Junior
Subordinated  Debentures  deposited in the Trust as trust assets.  See "--Voting
Rights."

DISTRIBUTIONS

       Distributions on the Preferred Securities will be fixed at an annual rate
of $ per Preferred Security.  Distributions in arrears for more than one quarter
will bear interest  thereon at the rate per annum of % (to the extent  permitted
by law), compounded quarterly.  The term "Distributions" as used herein includes
any such interest payable unless otherwise  stated.  The amount of distributions
payable for any period will be computed on the basis of a 360-day year of twelve
30 day months.

       Distributions on the Preferred Securities will be cumulative, will accrue
from , 1999 and, except as otherwise described below, will be payable on , , and
of each  year,  commencing  on ,  2000,  but only if,  and to the  extent  that,
interest payments are made in respect of Junior Subordinated  Debentures held by
the Property Trustee.

       So  long as AES shall not be in default in the payment of interest on the
Junior Subordinated Debentures, the Company has the


                                      S-16
<PAGE>

right  under  the  Indenture  to  defer  payments  of  interest  on  the  Junior
Subordinated  Debentures  by  extending  the  interest  payment  period (each an
"Extension Period") from time to time on the Junior Subordinated  Debentures for
a period not  exceeding  20  consecutive  quarterly  interest  periods and, as a
consequence,  the Trust would defer  quarterly  Distributions  on the  Preferred
Securities  (though such  Distributions  would  continue to accrue with interest
thereon  at the  rate of % per  annum,  compounded  quarterly)  during  any such
Extension  Period;  provided  that no such  period may extend  beyond the stated
maturity of the Junior  Subordinated  Debentures.  If the Company  exercises the
right to extend an interest  payment period,  the Company may not declare or pay
dividends on, or redeem, purchase, acquire or make a distribution or liquidation
payment with respect to, any of its common stock or preferred  stock during such
Extension  Period;  provided  that the  foregoing  will not  apply to any  stock
dividend by the Company payable in common stock. Prior to the termination of any
such Extension  Period,  the Company may further  extend such Extension  Period;
provided that such Extension  Period together with all such previous and further
extensions  thereof may not exceed 20 consecutive  quarterly  interest  periods.
Upon the termination of any Extension Period and the payment of all amounts then
due,  the  Company may  commence a new  Extension  Period,  subject to the above
requirements.  The Company may also prepay at any time all or any portion of the
interest  accrued  during an  Extension  Period.  Consequently,  there  could be
multiple  Extension Periods of varying lengths throughout the term of the Junior
Subordinated  Debentures,  not to exceed 20 consecutive quarters or to cause any
extension  beyond  the  maturity  of the  Junior  Subordinated  Debentures.  See
"Description of the Junior  Subordinated  Debentures -- Interest" and "-- Option
to Extend Interest Payment Period" herein and "Risk Factors" in the accompanying
prospectus.  Payments  of  accrued  distributions  will be payable to holders of
Preferred Securities as they appear on the books and records of the Trust on the
first record date after the end of an Extension Period.

       Distributions  on the  Preferred  Securities  must be  paid on the  dates
payable to the extent that the Property Trustee has cash on hand in the Property
Account to permit such  payment.  The funds  available for  distribution  to the
holders of the Preferred  Securities will be limited to payments received by the
Property  Trustee  in respect of the  Junior  Subordinated  Debentures  that are
deposited  in the  Trust  as  trust  assets.  See  "Description  of  the  Junior
Subordinated  Debentures." If the Company does not make interest payments on the
Junior Subordinated Debentures, the Property Trustee will not make distributions
on the Preferred  Securities.  Under the  Declaration,  if and to the extent the
Company  does make  interest  payments  on the  Junior  Subordinated  Debentures
deposited in the Trust as trust  assets,  the  Property  Trustee is obligated to
make  distributions  on the Trust Securities on a pro rata basis. The payment of
distributions  on the  Preferred  Securities  is  guaranteed by the Company on a
subordinated  basis as and to the extent  set forth  under  "Description  of the
Guarantees" herein and the "Description of the Preferred Securities  Guarantees"
in the accompanying prospectus. The Preferred Securities Guarantee is a full and
unconditional  guarantee  from the time of issuance of the Preferred  Securities
but the Preferred  Securities  Guarantee covers distributions and other payments
on the Preferred  Securities only if and to the extent that the Company has made
a payment  to the  Property  Trustee  of  interest  or  principal  on the Junior
Subordinated Debentures deposited in the Trust as trust assets.

       Distributions  on the  Preferred  Securities  will be made to the holders
thereof as they  appear on the books and  records  of the Trust on the  relevant
record dates,  which, as long as the Preferred  Securities  remain in book-entry
form, will be one Business Day prior to the relevant  Distribution payment date.
Distributions  payable on any Preferred  Securities that are not punctually paid
on any  Distribution  payment date as a result of the Company  having  failed to
make the corresponding  interest payment on the Junior  Subordinated  Debentures
will  forthwith  cease to be payable to the person in whose name such  Preferred
Securities  is  registered  on the  relevant  record  date,  and such  defaulted
Distribution  will instead be payable to the person in whose name such Preferred
Securities is registered on the special  record date  established by the Regular
Trustees, which record date shall correspond to the special record date or other
specified date determined in accordance with the Indenture; provided,


                                      S-17
<PAGE>

however,  that Distributions shall not be considered payable on any Distribution
payment date falling  within an Extension  Period unless the Company has elected
to make a full or partial payment of interest accrued on the Junior Subordinated
Debentures on such  Distribution  payment date.  Distributions  on the Preferred
Securities  will be paid  through the  Property  Trustee  who will hold  amounts
received  in respect  of the  Junior  Subordinated  Debentures  in the  Property
Account for the benefit of the holders of the Preferred  and Common  Securities.
Subject  to any  applicable  laws  and  regulations  and the  provisions  of the
Declaration,  each such payment will be made as described under "Book-Entry Only
Issuance -- The Depository Trust Company" below. In the event that the Preferred
Securities do not continue to remain in book-entry  form,  the Regular  Trustees
shall have the right to select  relevant  record  dates which shall be more than
one Business Day prior to the relevant payment dates.  The Declaration  provides
that the payment dates or record dates for the Preferred Securities shall be the
same  as the  payment  dates  and  record  dates  for  the  Junior  Subordinated
Debentures. All distributions paid with respect to the Trust Securities shall be
paid on a pro rata basis to the holders thereof entitled thereto. If any date on
which distributions are to be made on the Preferred Securities is not a Business
Day,  then payment of the  distribution  to be made on such date will be made on
the next  succeeding  day that is a Business  Day (and  without any  interest or
other payment in respect of any such delay) except that, if such Business Day is
in the  next  succeeding  calendar  year,  such  payment  shall  be  made on the
immediately  preceding Business Day, in each case with the same force and effect
as if made on such date.  "Business Day" shall mean any day other than Saturday,
Sunday or any other day on which banking institutions in the City of New York in
the State of New York are permitted or required by any applicable law to close.


CONVERSION RIGHTS

General

       The Preferred  Securities  will be  convertible  at any time prior to the
close of business on , 2029 (or in the case of the Preferred  Securities  called
for redemption,  prior to the close of the business on the Business Day prior to
the Redemption Date) (the "Conversion  Expiration  Date"),  at the option of the
holders thereof and in the manner described  below,  into shares of common stock
at an  initial  conversion  rate of share of  common  stock  for each  Preferred
Securities  (equivalent  to a conversion  price of $ per security  (the "Initial
Conversion  Price")),  subject to adjustment as described  under "--  Conversion
Price   Adjustments  --  General"  and  "--  Conversion  Price   Adjustments  --
Fundamental Change" below. If a Preferred Security is surrendered for conversion
after  the  close of  business  on any  regular  record  date for  payment  of a
Distribution   and  before  the  opening  of   business  on  the   corresponding
Distribution   payment  date,  then,   notwithstanding   such  conversion,   the
Distribution  payable on such Distribution  payment date will be paid in cash to
the person in whose name the  Preferred  Security is  registered at the close of
business on such record date, and (other than a Preferred  Security or a portion
of a Preferred  Security  called for  redemption on a redemption  date occurring
after such  record  date and prior to such  Distribution  payment  date) when so
surrendered  for  conversion,  the  Preferred  Security must be  accompanied  by
payment of an amount  equal to the  Distribution  payable  on such  Distribution
payment date.


       The  terms  of  the  Preferred  Securities  provide  that a  holder  of a
Preferred Security wishing to exercise its conversion right shall surrender such
Preferred  Security,  together with an  irrevocable  conversion  notice,  to the
Property Trustee, as conversion agent (the "Conversion Agent"),  which shall, on
behalf of such holder, exchange such Preferred Security for an equivalent amount
of  Junior   Subordinated   Debentures  and  immediately   convert  such  Junior
Subordinated  Debentures  into common  stock.  Holders may obtain  copies of the
required form of the conversion  notice from the Conversion  Agent. So long as a
book-entry system for the Preferred Securities is in effect, however, procedures
for converting the Preferred Securities into shares of common stock will differ,
as  described  under  "--  Book-Entry  Only  Issuance  -- The  Depository  Trust
Company."


       No  fractional  shares  of  common  stock  will  be issued as a result of
conversion, but in lieu


                                      S-18
<PAGE>

thereof such fractional interest will be paid by AES in cash based on the market
price of common stock on the date such Preferred  Securities are surrendered for
conversion.


Conversion Price Adjustments -- General


       The Initial Conversion Price is subject to adjustment (under formulas set
forth in the Indenture) in certain events, including:


       (i) the  issuance of common stock as a dividend or distribution on common
stock;


       (ii) certain subdivisions and combinations of common stock;


       (iii) the  issuance to all holders of common  stock of certain  rights or
warrants to purchase common stock at less than the then current market price;


       (iv) the  distribution  to all  holders  of  common  stock of (A)  equity
securities  of  the  Company  (other  than  common  stock),   (B)  evidences  of
indebtedness of the Company and/or (C) other assets (including  securities,  but
excluding (1) any rights or warrants  referred to in clause (iii) above, (2) any
rights or warrants to acquire  any  capital  stock of any entity  other than the
Company,  (3) any dividends or distributions in connection with the liquidation,
dissolution  or winding-up of the Company,  (4) any dividends  payable solely in
cash  that may  from  time to time be fixed  by the  Board of  Directors  of the
Company and (5) any dividends or distributions referred to in clause (i) above);


       (v)  distributions  to all holders of common  stock,  consisting of cash,
excluding  (a) any  cash  dividends  on  common  stock  to the  extent  that the
aggregate cash dividends per share of common stock in any  consecutive  12-month
period do not exceed the greater of (x) the amount per share of common  stock of
the cash dividends paid on common stock in the  immediately  preceding  12-month
period, to the extent that such dividends for the immediately preceding 12-month
period did not require an adjustment of the  conversion  price  pursuant to this
clause  (v) (as  adjusted  to reflect  subdivisions  or  combinations  of common
stock), and (y) 15% of the average of the daily Closing Price (as defined in the
Indenture) of common stock for the ten  consecutive  Trading Days (as defined in
the  Indenture)  immediately  prior to the date of declaration of such dividend,
and (b) any  dividend  or  distribution  in  connection  with  the  liquidation,
dissolution  or winding up of the Company or a redemption  of any rights  issued
under a rights agreement;  provided,  however,  that no adjustment shall be made
pursuant to this clause (v) if such  distribution  would otherwise  constitute a
Fundamental Change (as defined below) and be reflected in a resulting adjustment
described below; and

       (vi)  payment in respect of a tender or exchange  offer by the Company or
any  subsidiary  of the Company for common stock to the extent that the cash and
value of any other  consideration  included in such  payment per share of common
stock exceed (by more than 10%,  with any smaller  excess being  disregarded  in
computing  the  adjustment  provided  hereby) the first  reported sale price per
share of common stock on the Trading Day next succeeding the Expiration Time (as
defined in the Indenture) for such tender or exchange offer.

       If any adjustment is required to be made as set forth in clause (v) above
as a result of a distribution  which is a dividend described in subclause (a) of
clause (v) above,  such adjustment  would be based upon the amount by which such
distribution  exceeds  the  amount  of the  dividend  permitted  to be  excluded
pursuant to such subclause (a) of clause (v). If an adjustment is required to be
made as set forth in clause (v) above as a result of a distribution which is not
such a  dividend,  such  adjustment  would be based upon the full amount of such
distribution.  If an  adjustment  is  required to be made as set forth in clause
(vi) above,  such adjustment  would be calculated based upon the amount by which
the aggregate  consideration paid for the common stock acquired in the tender or
exchange  offer  exceeds  110% of the  value of such  shares  based on the first
reported  sale price of common  stock on the  Trading  Day next  succeeding  the
Expiration  Time.  In lieu of making such a conversion  price  adjustment in the
case of certain  dividends or  distributions,  the Company may provide that upon
the conversion of the Preferred  Securities the holder converting such Preferred
Securities will receive, in addition to the common stock to which such holder is
entitled,  the cash,  securities or other  property which such holder would have
received  if such  holder  had,  immediately  prior to the record  date for such
dividend or distribution, converted its Preferred Securities into common stock.


                                      S-19
<PAGE>

       No  adjustment  in the  conversion  price  will be  required  unless  the
adjustment would require a change of at least 1% in the conversion price then in
effect; provided,  however, that any adjustment that would otherwise be required
to be made shall be carried  forward  and taken into  account in any  subsequent
adjustment.

       The Company from time to time may, to the extent permitted by law, reduce
the  conversion  price by any amount for any period of at least 20 Business Days
(as defined in the Indenture),  in which case the Company shall give at least 15
days' notice of such reduction.  In particular,  the Company may, at its option,
make such  reduction  in the  conversion  price,  in addition to those set forth
above,  as the Company  deems  advisable  to avoid or diminish any income tax to
holders of common stock resulting from any dividend or distribution of stock (or
rights to acquire  stock) or from any event  treated as such for tax purposes or
for any other reasons.  See "Certain  Federal Tax  Consequences -- Adjustment of
Conversion Price."

Conversion Price Adjustments -- Fundamental Change

       In the event  that the  Company  shall be a party to any  transaction  or
series of transactions  constituting a Fundamental  Change,  including,  without
limitation,  (i) any recapitalization or reclassification of common stock (other
than a change in par value or as a result of a  subdivision  or  combination  of
common  stock);  (ii) any  consolidation  or merger of the Company  with or into
another  corporation  as a result  of which  holders  of common  stock  shall be
entitled to receive securities or other property or assets (including cash) with
respect to or in exchange  for common  stock (other than a merger which does not
result  in a  reclassification,  conversion,  exchange  or  cancellation  of the
outstanding  common stock);  (iii) any sale or transfer of all or  substantially
all of the  assets  of the  Company;  or (iv)  any  compulsory  share  exchange,
pursuant  to any of which  holders of common  stock shall be entitled to receive
other securities,  cash or other property,  then appropriate  provision shall be
made so that the holder of each Preferred  Security then outstanding  shall have
the right  thereafter to convert such Preferred  Securities only into (x) if any
such  transaction  does not  constitute  a Common Stock  Fundamental  Change (as
defined below),  the kind and amount of the  securities,  cash or other property
that would have been  receivable upon such  recapitalization,  reclassification,
consolidation,  merger,  sale,  transfer  or share  exchange  by a holder of the
number of shares of common stock  issuable  upon  conversion  of such  Preferred
Security   immediately   prior  to  such   recapitalization,   reclassification,
consolidation, merger, sale, transfer or share exchange, after, in the case of a
Non-Stock Fundamental Change (as defined below), giving effect to any adjustment
in the  conversion  price  in  accordance  with  clause  (i)  of  the  following
paragraph,   and  (y)  if  any  such  transaction  constitutes  a  Common  Stock
Fundamental  Change,  shares of common stock of the kind  received by holders of
common  stock as result of such  Common  Stock  Fundamental  Change in an amount
determined  in  accordance  with clause  (ii) of the  following  paragraph.  The
company  formed by such  consolidation  or  resulting  from such merger or which
acquires  such assets or which  acquires the common  stock,  as the case may be,
shall  enter  into  a  supplemental   indenture  with  the  Indenture   Trustee,
satisfactory in form to the Indenture  Trustee and executed and delivered to the
Indenture  Trustee,  the provisions of which shall  establish  such right.  Such
supplemental   indenture  shall  provide  for  adjustments   which,  for  events
subsequent  to the effective  date of such  supplemental  indenture  shall be as
nearly equivalent as practical to the relevant  adjustments  provided for in the
preceding paragraphs and in this paragraph.


       Notwithstanding any other provision in the preceding  paragraphs,  if any
Fundamental  Change  occurs,  the  conversion  price in effect  will be adjusted
immediately after that Fundamental Change as follows:


        (i) in the case of a Non-Stock  Fundamental Change, the conversion price
per share of common  stock  immediately  following  such  Non-Stock  Fundamental
Change will be the lower of (A) the conversion price in effect immediately prior
to such Non-Stock Fundamental Change, but after giving effect to any other prior
adjustments  effected pursuant to the preceding  paragraphs,  and (B) the result
obtained by multiplying  the greater of the Applicable  Price (as defined below)
or the then applicable  Reference  Market Price (as defined below) by a fraction
of which the numerator


                                      S-20
<PAGE>

will be 100 and the  denominator  of which  will be an amount  based on the date
such Non-Stock  Fundamental  Change occurs.  For the 12-month period beginning ,
1999, the denominator will be , and the denominator will decrease by during each
successive 12-month period;  provided, that the denominator shall in no event be
less than 100.


        (ii) in the case of a Common Stock  Fundamental  Change,  the conversion
price  per  share  of  common  stock  immediately  following  the  Common  Stock
Fundamental  Change will be the conversion price in effect  immediately prior to
the Common Stock Fundamental  Change, but after giving effect to any other prior
adjustments  effected  pursuant to the  preceding  paragraphs,  multiplied  by a
fraction, the numerator of which is the Purchaser Stock Price (as defined below)
and the denominator of which is the Applicable Price; provided, however, that in
the event of a Common Stock Fundamental Change in which (A) 100% of the value of
the  consideration  received  by a holder of common  stock  (subject  to certain
limited  exceptions)  is shares of common  stock of the  successor,  acquiror or
other  third  party  (and cash,  if any,  paid with  respect  to any  fractional
interests  in the  shares  of  common  stock  resulting  from the  Common  Stock
Fundamental  Change) and (B) all of the common stock (subject to certain limited
exceptions)  shall have been  exchanged  for,  converted  into, or acquired for,
shares of common stock (and cash, if any, with respect to fractional  interests)
of the successor,  acquiror or other third party, the conversion price per share
of common stock immediately  following the Common Stock Fundamental Change shall
be the  conversion  price  in  effect  immediately  prior  to the  Common  Stock
Fundamental  Change  divided  by the  number of  shares  of common  stock of the
successor,  acquiror,  or other third party received by a holder of one share of
common stock as a result of the Common Stock Fundamental Change.


       The foregoing conversion price adjustments are designed,  in "Fundamental
Change"  transactions  where all or  substantially  all of the  common  stock is
converted into securities,  cash, or property and not more than 50% of the value
received by the holders of common stock consists of stock listed or admitted for
listing  subject to notice of  issuance  on a national  securities  exchange  or
quoted on the  Nasdaq  National  Market of the  Nasdaq  Stock  Market,  Inc.  (a
"Non-Stock  Fundamental Change," as defined herein), to increase the securities,
cash or property into which each Preferred Securities is convertible.

       In a Fundamental  Change  transaction  where all or substantially all the
common stock is converted into  securities,  cash, or property and more than 50%
of the value received by the holders of common stock (subject to certain limited
exceptions)  consists of listed or Nasdaq National Market traded common stock (a
"Common Stock Fundamental Change," as defined herein), the foregoing adjustments
are  designed  to provide in effect  that (a) where  common  stock is  converted
partly  into such  common  stock and partly  into  other  securities,  cash,  or
property,  each Preferred Securities will be convertible solely into a number of
shares of such common stock  determined so that the initial value of such shares
(measured as described in the definition of Purchaser  Stock Price below) equals
the value of the shares of common stock into which such Preferred Securities was
convertible  immediately before the transaction  (measured as aforesaid) and (b)
where common stock is converted  solely into such common stock,  each  Preferred
Securities  will be  convertible  into the same  number of shares of such common
stock  receivable by a holder of the number of shares of common stock into which
such Preferred Security was convertible immediately before such transaction.

       In determining the amount and type of consideration  received by a holder
of common stock in the event of a Fundamental Change,  consideration received by
a holder of common  stock  pursuant to a statutory  right of  appraisal  will be
disregarded.

       "Applicable  Price"  means  (i) in the event of a  Non-Stock  Fundamental
Change in which the holders of common  stock  receive  only cash,  the amount of
cash  receivable  by a holder of one share of common stock and (ii) in the event
of any other Fundamental  Change,  the average of the Closing Prices (as defined
in the  supplemental  indenture)  for one share of common  stock  during the ten
Trading Days immediately  prior to the record date for the  determination of the
holders of common stock entitled to receive cash, securities,  property or other
assets in connection with such Fundamental Change or, if there is no such


                                      S-21
<PAGE>

record  date,  prior to the date on which the  holders of the common  stock will
have the right to receive such cash, securities, property or other assets.

       "Common Stock Fundamental  Change" means any Fundamental  Change in which
more than 50% of the value (as  determined in good faith by the Company's  board
of directors) of the consideration  received by holders of common stock (subject
to certain limited exceptions)  pursuant to such transaction  consists of shares
of common stock that, for the ten consecutive  Trading Days immediately prior to
such  Fundamental  Change has been  admitted for listing or admitted for listing
subject to notice of issuance on a national securities exchange or quoted on the
Nasdaq National Market, provided, however, that a Fundamental Change will not be
a Common Stock  Fundamental  Change unless  either (i) the Company  continues to
exist  after the  occurrence  of such  Fundamental  Change  and the  outstanding
Preferred  Securities continue to exist as outstanding  Preferred  Securities or
(ii) the  outstanding  Preferred  Securities  continue  to  exist  as  Preferred
Securities and are  convertible  into shares of common stock of the successor to
the Company.

       "Fundamental  Change" means the occurrence of any transaction or event or
series of transactions or events pursuant to which all or  substantially  all of
the common stock is exchanged for,  converted into,  acquired for or constitutes
solely the right to receive cash, securities,  property or other assets (whether
by means of an exchange offer, liquidation, tender offer, consolidation, merger,
combination,   reclassification,   recapitalization  or  otherwise);   provided,
however, in the case of a plan involving more than one such transaction or event
for purposes of adjustment of the conversion price, such Fundamental Change will
be deemed to have occurred when  substantially  all of the common stock has been
exchanged for,  converted into, or acquired for or constitutes  solely the right
to receive cash,  securities,  property or other assets but the adjustment shall
be based upon the consideration that the holders of common stock received in the
transaction  or event as a result  of which  more than 50% of the  common  stock
shall have been  exchanged  for,  converted  into,  or  acquired  for,  or shall
constitute  solely the right to receive  such cash,  securities,  properties  or
other assets.

       "Non-Stock  Fundamental Change" means any Fundamental Change other than a
Common Stock Fundamental Change.

       "Purchaser  Stock  Price"  means,   with  respect  to  any  Common  Stock
Fundamental  Change,  the average of the Closing  Prices for one share of common
stock  received  by holders of common  stock in such  Common  Stock  Fundamental
Change during the ten Trading Days immediately  prior to the record date for the
determination  of the holders of common stock entitled to receive such shares of
common stock or, if there is no such record  date,  prior to the date upon which
the  holders of common  stock  shall have the right to  receive  such  shares of
common stock.

       "Reference  Market Price" will initially  mean $ (which unless  otherwise
specified in this prospectus  supplement or the accompanying  prospectus will be
66 2/3% of the last  reported  sale price per share of AES's common stock on the
NYSE on October , 1999) and, in the event of any  adjustment  to the  conversion
price other than as a result of a Fundamental Change, the Reference Market Price
will also be adjusted  so that the ratio of the  Reference  Market  Price to the
conversion  price after giving effect to any adjustment  will always be the same
as the ratio of the initial  Reference  Market  Price to the Initial  Conversion
Price of the Preferred Securities.

       Conversions  of the  Preferred  Securities  may be effected by delivering
them to the office or agency of the Company  maintained  for such purpose in the
Borough of Manhattan, the City of New York.

       Conversion  price  adjustments may, in certain  circumstances,  result in
constructive distributions that could be taxable as dividends under the Internal
Revenue  Code of  1986,  as  amended  (the  "Code"),  to  holders  of  Preferred
Securities  or to holders of common stock issued upon  conversion  thereof.  See
"Certain Federal Tax Consequences -- Adjustment of Conversion Price."

       No  adjustment  in the  conversion  price  will be  required  unless  the
adjustment would require a change of at least 1% in the conversion price then in
effect; provided,  however, that any adjustment that would otherwise be required
to be made shall be carried  forward  and taken into  account in any  subsequent
adjustment.

SPECIAL EVENT REDEMPTION OR DISTRIBUTION

       If, at any time,  a Tax Event or an  Investment  Company  Event  (each as
hereinafter  defined, and each a "Special Event") shall occur and be continuing,
the Trust shall, unless the Junior  Subordinated  Debentures are redeemed in the
limited circumstances  described below, be dissolved with the result that, after
satisfaction of creditors of the Trust, Junior  Subordinated  Debentures with an
aggregate  principal amount equal to the aggregate stated  liquidation amount of
the Preferred Securities and the Common Securities would be distributed on a pro
rata basis to the holders of the Preferred  Securities and the Common Securities
in liquidation of such holders' interests in the Trust, within 90 days following
the occurrence of such Special Event; provided, however, that in the case of the
occurrence of a Tax Event, as a condition of such dissolution and  distribution,
the Regular  Trustees  shall have received an opinion of  nationally  recognized
independent  tax  counsel   experienced  in  such  matters  (a  "No  Recognition
Opinion"),  which  opinion  may rely on any then  applicable  published  revenue
rulings of the Internal Revenue  Service,  to the effect that the holders of the
Preferred  Securities  will not  recognize  any gain or loss for  United  States
Federal income tax purposes as a result of such  dissolution and distribution of
Junior Subordinated  Debentures;  and, provided,  further,  that, if at the time
there is available to the Trust the opportunity to eliminate, within such 90 day
period,  the Special Event by taking some ministerial  action,  such as filing a
form or making an election,  or pursuing some other similar reasonable  measure,
which has no adverse  effect on the Trust or the  Company or the  holders of the
Preferred Securities, the Trust will pursue such measure in lieu of dissolution.
Furthermore,  if in the case of the  occurrence of a Tax Event,  (i) the Regular
Trustees  have  received an opinion (a  "Redemption  Tax Opinion") of nationally
recognized independent tax counsel experienced in such matters that, as a result
of a Tax Event,  there is more than an insubstantial risk that the Company would
be precluded from deducting the interest on the Junior  Subordinated  Debentures
for United States  federal  income tax purposes even if the Junior  Subordinated
Debentures  were  distributed to the holders of Preferred  Securities and Common
Securities in liquidation  of such holders'  interests in the Trust as described
above or (ii) the Regular  Trustees shall have been informed by such tax counsel
that a No  Recognition  Opinion  cannot be delivered  to the Trust,  the Company
shall have the  right,  upon not less than 30 nor more than 60 days  notice,  to
redeem  the  Junior  Subordinated  Debentures  in whole or in part for cash at a
redemption  price equal to 100% of the principal  amount to be redeemed plus any
accrued and unpaid  interest  thereon within 90 days following the occurrence of
such Tax Event, and promptly following such redemption  Preferred Securities and
Common  Securities with an aggregate  liquidation  amount equal to the aggregate
principal  amount of the Junior  Subordinated  Debentures  so  redeemed  will be
redeemed by the Trust at the  Redemption  Price on a pro rata  basis;  provided,
however,  that if at the time there is  available  to the Company or the Regular
Trustees the opportunity to eliminate,  within such 90 day period, the Tax Event
by taking some ministerial  action, such as filing a form or making an election,
or pursuing some other similar reasonable  measure,  which has no adverse effect
on the Trust,  the  Company  or the  holders of the  Preferred  Securities,  the
Company will pursue such measure in lieu of redemption and provided further that
the  Company  shall have no right to redeem the Junior  Subordinated  Debentures
while  the  Regular  Trustees  on behalf  of the  Trust  are  pursuing  any such
ministerial  action.  The Common Securities will be redeemed on a pro rata basis
with the  Preferred  Securities,  except  that if an Event of Default  under the
Declaration has occurred and is continuing, the Preferred Securities will have a
priority over the Common  Securities  with respect to payment of the  Redemption
Price.

       "Tax  Event"  means that the  Regular  Trustees  shall have  obtained  an
opinion of a nationally  recognized  independent tax counsel experienced in such
matters (a "Dissolution Tax Opinion") to the effect that on or after the date of
this  prospectus  supplement  as a result of (a) any amendment to, or change in,
the laws (or any  regulations  thereunder) of the United States or any political
subdivision  or taxing  authority  thereof or therein,  (b) any amendment to, or
change in, an  interpretation  or application of any such laws or regulations by
any  legislative  body,  court,  governmental  agency  or  regulatory  authority
(including the enactment of any  legislation and the publication of any judicial
decision or regulatory determination), (c) any


                                      S-23
<PAGE>

interpretation  or  pronouncement  that  provides for a position with respect to
such laws or regulations  that differs from the theretofore  generally  accepted
position  or (d) any  action  taken by any  governmental  agency  or  regulatory
authority,  which  amendment  or  change  is  enacted,  promulgated,  issued  or
effective or which  interpretation  or  pronouncement  is issued or announced or
which  action  is taken,  in each  case on or after the date of this  prospectus
supplement,  there is more than an insubstantial  risk that (i) the Trust is, or
will be within 90 days of the date  thereof,  subject to United  States  federal
income tax with respect to income accrued or received on the Junior Subordinated
Debentures,  (ii) the Trust  is, or will be within 90 days of the date  thereof,
subject  to more  than a de  minimis  amount  of other  taxes,  duties  or other
governmental  charges or (iii)  interest  payable by the Company to the Trust on
the Junior Subordinated Debentures is not, or within 90 days of the date thereof
will not be,  deductible  by the Company for United  States  federal  income tax
purposes.


       "Investment  Company  Event" means that the Regular  Trustees  shall have
received an opinion of nationally recognized  independent counsel experienced in
practice under the Investment  Company Act of 1940, as amended (the "1940 Act"),
that as a result of the  occurrence of a change in law or regulation or a change
in  interpretation  or application of law or regulation by any legislative body,
court, governmental agency or regulatory authority (a "Change in 1940 Act Law"),
there is more than an insubstantial risk that the Trust is or will be considered
an "investment  company" which is required to be registered  under the 1940 Act,
which  Change  in 1940 Act Law  becomes  effective  on or after the date of this
prospectus supplement.


       On the date fixed for any distribution of Junior Subordinated Debentures,
upon  dissolution  of the Trust,  (i) the  Preferred  Securities  and the Common
Securities  will no longer be deemed to be  outstanding,  (ii) the depositary or
its nominee,  as the record holder of the Preferred  Securities,  will receive a
registered   global   certificate  or  certificates   representing   the  Junior
Subordinated  Debentures to be delivered upon such  distribution,  and (iii) any
certificates representing Preferred Securities not held by the depositary or its
nominee will be deemed to represent  Junior  Subordinated  Debentures  having an
aggregate  principal amount equal to the aggregate stated liquidation amount of,
with an interest  rate  identical to the  distribution  rate of, and accrued and
unpaid  interest  equal to accrued and unpaid  distributions  on, such Preferred
Securities,  until such  certificates  are presented to the Company or its agent
for transfer or reissuance.

       There  can  be no  assurance  as to  the  market  price  for  the  Junior
Subordinated  Debentures  which may be  distributed  in exchange  for  Preferred
Securities  if a  dissolution  and  liquidation  of the  Trust  were  to  occur.
Accordingly,   the  Junior  Subordinated   Debentures  which  the  investor  may
subsequently receive on dissolution and liquidation of the Trust, may trade at a
discount  to the price of the  Preferred  Securities  exchanged.  If the  Junior
Subordinated  Debentures are distributed to the holders of Preferred  Securities
upon the dissolution of the Trust, the Company will use its best efforts to list
the Junior  Subordinated  Debentures  on the NYSE or on such other  exchange  on
which the Preferred Securities are then listed.


MANDATORY REDEMPTION

       Upon the  repayment  of the Junior  Subordinated  Debentures,  whether at
maturity,  upon  redemption  or otherwise,  the proceeds from such  repayment or
payment  will be  promptly  applied to redeem  Preferred  Securities  and common
securities  having  an  aggregate   liquidation   amount  equal  to  the  Junior
Subordinated  Debentures so repaid, upon not less than 30 nor more than 60 days'
notice,  at the Redemption  Price. The common  securities will be entitled to be
redeemed on a pro rata basis with the  Preferred  Securities,  except that if an
Event of Default  under the  Declaration  has  occurred and is  continuing,  the
Preferred  Securities  will have a  priority  over the  common  securities  with
respect to payment of the Redemption Price.  Subject to the foregoing,  if fewer
than all  outstanding  Preferred  Securities  and  Common  Securities  are to be
redeemed,  the Preferred  Securities and Common Securities will be redeemed on a
pro rata basis. In the event fewer than all outstanding Preferred Securities are
to be redeemed,  Preferred Securities  registered in the name of and held by DTC
or


                                      S-24
<PAGE>

its  nominee  will  be  redeemed  as  described under "-- Redemption Procedures"
below.


REDEMPTION PROCEDURES

       The Trust may not redeem any outstanding  Preferred Securities unless all
accrued and unpaid  distributions have been paid on all Preferred Securities for
all quarterly distribution periods terminating on or prior to the date of notice
of redemption.

       If the  Trust  gives a notice  of  redemption  in  respect  of  Preferred
Securities (which notice will be irrevocable) then, by 12:00 noon, New York City
time,  on the  redemption  date and  provided  that the  Company has paid to the
Property  Trustee a  sufficient  amount of cash in  connection  with the related
redemption  or maturity of the Junior  Subordinated  Debentures,  the Trust will
irrevocably  deposit with the Depositary  funds sufficient to pay the applicable
Redemption  Price  and will give the  Depositary  irrevocable  instructions  and
authority  to  pay  the  Redemption  Price  to  the  holders  of  the  Preferred
Securities.  See "Book-Entry  Only Issuance -- The Depository Trust Company." If
notice of  redemption  shall have been given and funds  deposited  as  required,
then,  immediately  prior to the close of business on the date of such  deposit,
distributions  will  cease to  accrue on the  Preferred  Securities  called  for
redemption,   such  Preferred  Securities  shall  no  longer  be  deemed  to  be
outstanding and all rights of holders of such Preferred Securities so called for
redemption  will  cease,  except  the  right of the  holders  of such  Preferred
Securities  to receive  the  Redemption  Price,  but  without  interest  on such
Redemption  Price.  Neither  the  Trustees  nor the Trust  shall be  required to
register or cause to be  registered  the  transfer of any  Preferred  Securities
which have been so called for  redemption.  If any date fixed for  redemption of
Preferred Securities is not a Business Day, then payment of the Redemption Price
payable on such date will be made on the next  succeeding day that is a Business
Day (and  without any  interest  or other  payment in respect of any such delay)
except that, if such Business Day falls in the next calendar year,  such payment
will be made on the  immediately  preceding  Business Day, in each case with the
same  force  and  effect as if made on such date  fixed for  redemption.  If the
Company fails to repay Junior Subordinated Debentures on maturity or on the date
fixed for this  redemption or if payment of the  Redemption  Price in respect of
Preferred  Securities  is  improperly  withheld  or refused  and not paid by the
Property  Trustee  or by  the  Company  pursuant  to  the  Preferred  Securities
Guarantee described under "Description of the Preferred  Securities  Guarantees"
in the accompanying prospectus,  distributions on such Preferred Securities will
continue  to  accrue,  from  the  original  redemption  date  of  the  Preferred
Securities to the date of payment, in which case the actual payment date will be
considered  the date  fixed for  redemption  for  purposes  of  calculating  the
Redemption Price.

       In the event that fewer than all of the outstanding  Preferred Securities
are to be redeemed, the Preferred Securities will be redeemed as described below
under "Book-Entry Only Issuance -- The Depository Trust Company."

       If a partial  redemption of the Preferred  Securities would result in the
delisting of the  Preferred  Securities by any national  securities  exchange or
other  organization  on which the  Preferred  Securities  are then  listed,  the
Company  pursuant  to  the  Indenture  will  only  redeem  Junior   Subordinated
Debentures  in whole and, as a result,  the Trust may only redeem the  Preferred
Securities in whole.

       Subject  to  the  foregoing  and  applicable  law   (including,   without
limitation,  United States federal  securities  laws), the Company or any of its
subsidiaries  may at any  time  and  from  time  to  time  purchase  outstanding
Preferred Securities by tender, in the open market or by private agreement.


LIQUIDATION DISTRIBUTION UPON DISSOLUTION

       In the event of any voluntary or  involuntary  dissolution,  liquidation,
winding-up or termination of the Trust, the holders of the Preferred  Securities
and Common  Securities at the date of dissolution,  winding-up or termination of
the Trust will be  entitled  to  receive  on a pro rata basis  solely out of the
assets of the Trust,  after  satisfaction  of  liabilities  of creditors (to the
extent not satisfied by the Company as provided in the  Declaration),  an amount
equal  to the  aggregate  of the  stated  liquidation  amount  of $50 per  Trust
Security  plus accrued and unpaid  distributions  thereon to the date of payment
(such amount being the


                                      S-25
<PAGE>

"Liquidation  Distribution"),  unless,  in  connection  with  such  dissolution,
liquidation,  winding-up or termination,  Junior  Subordinated  Debentures in an
aggregate  principal amount equal to the aggregate stated  liquidation amount of
such Trust Securities and bearing accrued and unpaid interest in an amount equal
to the  accrued  and unpaid  distributions  on such Trust  Securities,  shall be
distributed  on a pro rata basis to the holders of the Preferred  Securities and
Common Securities in exchange therefor.

       If, upon any such dissolution,  the Liquidation  Distribution can be paid
only in part because the Trust has insufficient  assets available to pay in full
the aggregate Liquidation Distribution, then the amounts payable directly by the
Trust on the Preferred  Securities and the Common  Securities shall be paid on a
pro rata basis. The holders of the Common Securities will be entitled to receive
distributions  upon any such dissolution on a pro rata basis with the holders of
the  Preferred  Securities,  except  that  if an  Event  of  Default  under  the
Declaration has occurred and is continuing,  the Preferred Securities shall have
a priority over the Common Securities with respect to payment of the Liquidation
Distribution.

       Pursuant to the Declaration,  the Trust shall terminate:  (1) on November
1, 2031,  the  expiration  of the term of the  Trust;  (2) when all of the Trust
Securities  shall have been called for redemption and the amounts  necessary for
redemption  thereof  shall have been paid to the holders of Trust  Securities in
accordance with the terms of the Trust Securities; or (3) when all of the Junior
Subordinated  Debentures  shall have been  distributed  to the  holders of Trust
Securities in exchange for all of the Trust  Securities  in accordance  with the
terms of the Trust Securities.


NO MERGER, CONSOLIDATION OR AMALGAMATION OF THE TRUST

       The Trust may not  consolidate,  amalgamate,  merge  with or into,  or be
replaced  by, or convey,  transfer  or lease its  properties  and assets to, any
corporation or other entity.


DECLARATION EVENTS OF DEFAULT

       An Indenture Event of Default (as defined in the accompanying prospectus)
will  constitute an event of default under the  Declaration  with respect to the
Trust  Securities  (an  "Event  of  Default");  provided  that  pursuant  to the
Declaration,  the holder of the Common  Securities will be deemed to have waived
any such Event of Default with respect to the Common Securities until all Events
of Default with respect to the Preferred  Securities  have been cured or waived.
Until all such Events of Default with respect to the Preferred  Securities  have
been so cured or waived, the Property Trustee will be deemed to be acting solely
on behalf of the holders of the  Preferred  Securities,  and only the holders of
the Preferred Securities will have the right to direct the Property Trustee with
respect to certain  matters under the  Declaration  and  consequently  under the
Indenture.  In the event that any Event of Default with respect to the Preferred
Securities is waived by the holders of the  Preferred  Securities as provided in
the Declaration,  the holders of Common  Securities  pursuant to the Declaration
have agreed that such waiver also  constitutes a waiver of such Event of Default
with respect to the Common  Securities  for all purposes  under the  Declaration
without  any  further  act,  vote  or  consent  of the  holders  of  the  Common
Securities. See "Voting Rights" below.

       Upon the occurrence of an Event of Default,  the Property  Trustee as the
holder of all of the Junior  Subordinated  Debentures  will have the right under
the   Indenture  to  declare  the  principal  of  and  interest  on  the  Junior
Subordinated  Debentures to be  immediately  due and payable.  In addition,  the
Property  Trustee  will  have the  power to  exercise  all  rights,  powers  and
privileges  under the Indenture.  See  "Description  of the Junior  Subordinated
Debentures."


VOTING RIGHTS

       Except as provided  below,  under  "--Modification  and  Amendment of the
Declaration"  below and "Description of the Preferred  Securities  Guarantees --
Amendments  and  Assignment"  in the  accompanying  prospectus  and as otherwise
required by the Business Trust Act, the Trust Indenture Act and the Declaration,
the holders of the Preferred Securities will have no voting rights.

       Subject to the requirements of this paragraph,  the holders of a majority
in aggregate  liquidation amount of the Preferred  Securities have the right (i)
on behalf of all


                                      S-26
<PAGE>

holders of  Preferred  Securities,  to waive any past  default  that is waivable
under  the  Declaration  and  (ii) to  direct  the  time,  method  and  place of
conducting any proceeding for any remedy available to the Property  Trustee,  or
exercising  any trust or power  conferred  upon the Property  Trustee  under the
Declaration,  including the right to direct the Property Trustee,  as the holder
of the Junior Subordinated Debentures,  to (A) direct the time, method and place
of conducting any proceeding for any remedy  available to the Indenture  Trustee
(as defined herein),  or executing any trust or power conferred on the Indenture
Trustee with respect to the Junior Subordinated  Debentures,  (B) waive any past
default that is waivable  under Section 6.06 of the  Indenture,  or (C) exercise
any right to rescind or annul a declaration that the principal of all the Junior
Subordinated Debentures shall be due and payable;  provided that where a consent
under  the  Indenture  would  require  the  consent  of (a)  holders  of  Junior
Subordinated  Debentures  representing  a specified  percentage  greater  than a
majority in principal amount of the Junior  Subordinated  Debentures or (b) each
holder of Junior Subordinated Debentures affected thereby, no such consent shall
be given by the Property  Trustee  without the prior  consent of, in the case of
clause (a) above,  holders of Preferred  Securities  representing such specified
percentage of the aggregate  liquidation amount of the Preferred  Securities or,
in the case of  clause  (b)  above,  each  holder  of all  Preferred  Securities
affected  thereby.  The Property Trustee shall not revoke any action  previously
authorized  or approved by a vote of the holders of  Preferred  Securities.  The
Property  Trustee shall notify all holders of record of Preferred  Securities of
any notice of default  received from the  Indenture  Trustee with respect to the
Junior Subordinated  Debentures.  Other than with respect to directing the time,
method and place of conducting any  proceeding  for any remedy  available to the
Property  Trustee or the  Indenture  Trustee as set forth  above,  the  Property
Trustee shall be under no obligation to take any of the foregoing actions at the
direction of the holders of the Preferred Securities unless the Property Trustee
shall have obtained an opinion of nationally recognized  independent tax counsel
recognized  as expert in such  matters to the effect  that the Trust will not be
classified  for United  States  federal  income tax  purposes as an  association
taxable as a corporation  or a partnership on account of such action and will be
treated  as a grantor  trust for  United  States  federal  income  tax  purposes
following such action. If the Property Trustee fails to enforce its rights under
the  Declaration  (including,   without  limitation,   its  rights,  powers  and
privileges  as  a  holder  of  the  Junior  Subordinated  Debentures  under  the
Indenture),  any holder of Preferred  Securities may, to the extent permitted by
applicable law, after a period of 30 days has elapsed from such holder's written
request to the  Property  Trustee  to enforce  such  rights,  institute  a legal
proceeding directly against the Company to enforce the Property Trustee's rights
under the Declaration,  without first instituting a legal proceeding against the
Property  Trustee  or any  other  Person.  In  addition,  in case of an Event of
Default  which is  attributed  to the failure of the Company to pay  interest or
principal  on  the  Junior  Subordinated   Debentures,  a  holder  of  Preferred
Securities  may directly  institute a proceeding  for  enforcement of payment to
such  holder of the  principal  of, or  interest  on,  the  Junior  Subordinated
Debentures having a principal amount equal to the aggregate  liquidation  amount
of the Preferred  Securities of such holder. See "The AES Trusts -- The Property
Trustee" in the accompanying prospectus.


       A waiver of an Indenture Event of Default by the Property  Trustee at the
direction of holders of the Preferred Securities will constitute a waiver of the
corresponding  Event of Default  under the  Declaration  in respect of the Trust
Securities.


       In the event the  consent  of the  Property  Trustee as the holder of the
Junior  Subordinated  Debentures  is  required  under the Trust  Indenture  with
respect to any amendment,  modification or termination of the Trust Indenture or
the Junior  Subordinated  Debentures,  the Property  Trustee  shall  request the
direction of the holders of the Trust Securities with respect to such amendment,
modification  or  termination  and shall vote with  respect  to such  amendment,
modification  or termination as directed by a majority in liquidation  amount of
the Trust Securities voting together as a single class; provided,  however, that
where any such amendment,  modification or termination under the Indenture would
require the consent of holders of Junior Subordinated Debentures representing a


                                      S-27
<PAGE>

specified  percentage  greater than a majority in principal amount of the Junior
Subordinated Debentures,  the Property Trustee may only give such consent at the
direction  of the  holders  of  Trust  Securities  representing  such  specified
percentage of the aggregate  liquidation  amount of the Trust  Securities;  and,
provided,  further,  that the Property  Trustee  shall be under no obligation to
take any such action in  accordance  with the  directions  of the holders of the
Trust  Securities  unless  the  Property  Trustee  has  obtained  an  opinion of
nationally  recognized  independent  tax  counsel  recognized  as expert in such
matters to the effect that the Trust will not be  classified  for United  States
federal  income tax purposes as an  association  taxable as a  corporation  or a
partnership on account of such action and will be treated as a grantor trust for
United States Federal income tax purposes following such action.

       Any required approval or direction of holders of Preferred Securities may
be given at a separate meeting of holders of Preferred  Securities  convened for
such purpose, at a meeting of all of the holders of Trust Securities or pursuant
to written  consent.  The Regular Trustees will cause a notice of any meeting at
which  holders of Preferred  Securities  are entitled to vote,  or of any matter
upon which  action by  written  consent  of such  holders is to be taken,  to be
mailed to each holder of record of Preferred  Securities.  Each such notice will
include a statement  setting  forth (i) the date of such  meeting or the date by
which such action is to be taken; (ii) a description of any resolution  proposed
for  adoption at such  meeting on which such  holders are entitled to vote or of
such matter upon which written consent is sought; and (iii) instructions for the
delivery of proxies or consents.

       No vote  or  consent  of the  holders  of  Preferred  Securities  will be
required for the Trust to redeem and cancel  Preferred  Securities or distribute
Junior Subordinated Debentures in accordance with the Declaration.

       Notwithstanding that holders of Preferred Securities are entitled to vote
or consent under any of the circumstances  described above, any of the Preferred
Securities at such time that are owned by the Company or by any entity  directly
or indirectly  controlling  or controlled by or under direct or indirect  common
control with the Company shall not be entitled to vote or consent and shall, for
purposes of such vote or consent, be treated as if they were not outstanding.

       The procedures by which persons owning Preferred Securities registered in
the name of and held by DTC or its nominee may exercise  their voting rights are
described  under  "Book-Entry  Only Issuance -- The  Depository  Trust  Company"
below.  Holders of the Preferred  Securities  will have no rights to increase or
decrease  the number of  Trustees  or to  appoint,  remove or replace a Trustee,
which rights are vested exclusively in the holders of the Common Securities.


MODIFICATION AND AMENDMENT OF THE DECLARATION

       The  Declaration may be modified and amended on approval of a majority of
the Regular Trustees,  provided, that, if any proposed modification or amendment
provides  for,  or the Regular  Trustees  otherwise  propose to effect,  (a) any
action that would adversely affect the powers,  preferences or special rights of
the  Trust  Securities,  whether  by way of  amendment  to  the  Declaration  or
otherwise, or (b) the dissolution,  winding-up or termination of the Trust other
than  pursuant  to the  terms  of  the  Declaration,  then  the  holders  of the
outstanding  Trust  Securities  as a  class  will  be  entitled  to vote on such
amendment  or proposal  and such  amendment  or proposal  shall not be effective
except with the  approval of at least a majority  in  liquidation  amount of the
Trust  Securities,  provided that if any amendment or proposal referred to above
would adversely affect only the Preferred  Securities or the Common  Securities,
then only the  affected  class will be  entitled  to vote on such  amendment  or
proposal and such amendment or proposal  shall not be effective  except with the
approval of a majority in liquidation amount of such class of Trust Securities.


       Notwithstanding  the foregoing,  (i) no amendment or modification  may be
made to the  Declaration  unless the Regular  Trustees  shall have  obtained (a)
either a ruling  from the  Internal  Revenue  Service  or a written  unqualified
opinion of nationally  recognized  independent  tax counsel  experienced in such
matters  to the  effect  that  such  amendment  will not  cause  the Trust to be
classified  for United  States  federal  income tax  purposes as an  association
taxable as a corporation or a partnership and to the effect that


                                      S-28
<PAGE>

the Trust will  continue to be treated as a grantor trust for purposes of United
States  federal  income  taxation  and  (b) a  written  unqualified  opinion  of
nationally  recognized  independent  counsel  experienced in such matters to the
effect  that  such  amendment  will not  cause  the  Trust to be an  "investment
company"  which is required to be  registered  under the 1940 Act;  (ii) certain
specified  provisions of the  Declaration may not be amended without the consent
of all  of the  holders  of the  Trust  Securities;  (iii)  no  amendment  which
adversely  affects the rights,  powers and  privileges  of the Property  Trustee
shall be made  without the consent of the Property  Trustee;  (iv) Article IV of
the Declaration relating to the obligation of the Company to purchase the Common
Securities and to pay certain obligations and expenses of the Trust as described
under "The AES Trusts" in the accompanying prospectus may not be amended without
the consent of the Company;  and (v) the rights of holders of Common  Securities
under Article V of the Declaration to increase or decrease the number of, and to
appoint, replace or remove, Trustees shall not be amended without the consent of
each holder of Common Securities.

       The  Declaration  further  provides  that it may be amended  without  the
consent of the holders of the Trust  Securities to (i) cure any ambiguity;  (ii)
correct or supplement any provision in the Declaration  that may be defective or
inconsistent  with any other provision of the  Declaration;  (iii) to add to the
covenants,  restrictions  or obligations of the Company;  and (iv) to conform to
changes in, or a change in  interpretation  or  application  of certain 1940 Act
requirements  by the Commission,  which amendment does not adversely  affect the
rights, preferences or privileges of the holders.

BOOK-ENTRY ONLY ISSUANCE -- THE DEPOSITORY TRUST COMPANY

       The Depository  Trust Company  ("DTC") will act as securities  depositary
for the Preferred  Securities.  The Preferred  Securities will be issued only as
fully registered securities registered in the name of DTC or its nominee. One or
more   fully-registered   global  Preferred  Securities   certificates  (each  a
"Preferred  Securities  Global  Certificate"),  representing the total aggregate
number of Preferred Securities, will be issued and will be deposited with DTC.

       The  laws  of some  jurisdictions  require  that  certain  purchasers  of
securities  take physical  delivery of securities in definitive  form. Such laws
may impair the ability to transfer  beneficial  interests in a global  Preferred
Securities.


       DTC is a  limited-purpose  trust  company  organized  under  the New York
Banking Law, a "banking organization" within the meaning of the New York Banking
Law, a member of the Federal Reserve System, a "clearing corporation" within the
meaning  of the New  York  Uniform  Commercial  Code,  and a  "clearing  agency"
registered  pursuant to the  provisions  of Section 17A of the Exchange Act. DTC
holds  securities that its participants  ("Participants")  deposit with DTC. DTC
also facilitates the settlement among  Participants of securities  transactions,
such as  transfers  and  pledges,  in deposited  securities  through  electronic
computerized book-entry changes in Participants'  accounts,  thereby eliminating
the need for physical movement of securities  certificates.  Direct Participants
include  securities  brokers  and  dealers,  banks,  trust  companies,  clearing
corporations,  and certain other organizations ("Direct  Participants").  DTC is
owned by a number of its Direct Participants and by the NYSE, the American Stock
Exchange,  Inc., and the National Association of Securities Dealers, Inc. Access
to the DTC system is also  available  to others such as  securities  brokers and
dealers,  banks and trust  companies  that clear through or maintain a custodial
relationship with a Direct Participant, either directly or indirectly ("Indirect
Participants").  The rules  applicable to DTC and its  Participants  are on file
with the Securities and Exchange Commission.


       Upon  issuance of a Preferred  Securities  Global  Certificate,  DTC will
credit  on its  book-entry  registration  and  transfer  system  the  number  of
Preferred Securities represented by such Preferred Securities Global Certificate
to the  accounts of  institutions  that have  accounts  with DTC.  Ownership  of
beneficial  interests  in a  Preferred  Securities  Global  Certificate  will be
limited to Participants or persons that may hold interests through Participants.
The ownership  interest of each actual  purchaser of each  Preferred  Securities
("Beneficial  Owner")  is in turn to be  recorded  on the  Direct  and  Indirect
Participants'  records.  Beneficial Owners will not receive written confirmation
from DTC of their  purchases,  but  Beneficial  Owners are  expected  to receive
written confirmations providing


                                      S-29
<PAGE>

details of the transactions,  as well as periodic  statements of their holdings,
from the Direct or Indirect  Participants  through which the  Beneficial  Owners
purchased  Preferred  Securities.   Transfers  of  ownership  interests  in  the
Preferred  Securities  are to be  accomplished  by entries  made on the books of
Participants acting on behalf of Beneficial Owners.

       DTC has no knowledge  of the actual  Beneficial  Owners of the  Preferred
Securities;  DTC's records reflect only the identity of the Direct  Participants
to whose accounts such Preferred  Securities are credited,  which may or may not
be the Beneficial  Owners.  The Participants will remain responsible for keeping
account of their holdings on behalf of their  customers.  So long as DTC, or its
nominee, is the owner of a Preferred Securities Global Certificate,  DTC or such
nominee,  as the case may be,  will be  considered  the sole owner and holder of
record of the Preferred  Securities  represented  by such  Preferred  Securities
Global Certificate for all purposes.

       Conveyance  of  notices  and  other   communications  by  DTC  to  Direct
Participants,  by Direct  Participants to Indirect  Participants,  and by Direct
Participants and Indirect  Participants to Beneficial Owners will be governed by
arrangements among them, subject to any statutory or regulatory  requirements as
may be in effect from time to time.

       Redemption  notices  shall be sent to Cede & Co.  If less than all of the
Preferred  Securities are being  redeemed,  DTC will reduce pro rata (subject to
adjustment to eliminate fractional Preferred  Securities) the amount of interest
of each Direct Participant in the Preferred Securities to be redeemed.

       Although voting with respect to the Preferred  Securities is limited,  in
those  instances in which a vote is required,  neither DTC nor Cede & Co. itself
will  consent or vote with  respect  to  Preferred  Securities.  Under its usual
procedures,  DTC would  mail an Omnibus  Proxy to the Trust as soon as  possible
after the record date.  The Omnibus  Proxy  assigns Cede & Co.'s  consenting  or
voting  rights to those Direct  Participants  to whose  accounts  the  Preferred
Securities are credited on the record date  (identified in a listing attached to
the Omnibus proxy).

       Distribution  payments  on  the  Preferred  Securities  represented  by a
Preferred Series Global Certificate will be made by the Property Trustee to DTC.
DTC's  practice  is to credit  Direct  Participants'  accounts  on the  relevant
payment date in accordance with their respective holdings shown on DTC's records
unless DTC has  reason to  believe  that it will not  receive  payments  on such
payment date.  Payments by Participants to Beneficial Owners will be governed by
standing  instructions and customary practices and will be the responsibility of
such  Participants  and not of DTC,  the Trust or the  Company,  subject  to any
statutory  or  regulatory  requirements  as may be in effect  from time to time.
Payment of distributions to DTC is the responsibility of the Trust, disbursement
of such  payments  to Direct  Participants  is the  responsibility  of DTC,  and
disbursement of such payments to the Beneficial Owners is the  responsibility of
Direct and Indirect Participants.

       Except as  provided  herein,  a  Beneficial  Owner in a global  Preferred
Securities  certificate  will not be  entitled to receive  physical  delivery of
Preferred  Securities.  Accordingly,  each  Beneficial  Owner  must  rely on the
procedures of DTC to exercise any rights under the Preferred Securities.

       DTC may discontinue  providing its services as securities depository with
respect to the Preferred  Securities at any time by giving  reasonable notice to
the Trust. Under such circumstances, if a successor securities depository is not
obtained,  Preferred Securities  certificates will be required to be printed and
delivered.  Additionally,  the Trust may decide to discontinue use of the system
of book-entry transfers through DTC (or a successor depository).  In that event,
certificates for the Preferred Securities will be printed and delivered.


       The  information  in this  section  concerning  DTC and DTC's  book-entry
system has been obtained from sources that the Trust and the Company  believe to
be  reliable,  but the  Trust and the  Company  take no  responsibility  for the
accuracy thereof.

CONVERSION AGENT, REGISTRAR, TRANSFER AGENT AND PAYING AGENT

       The Property  Trustee will act as Conversion  Agent. In addition,  in the
event the  Preferred  Securities  do not remain in  book-entry  only  form,  the
following provisions will apply:

       Payment  of  distributions  and  payments  on redemption of the Preferred
Securities will be payable, the transfer of the Preferred Securities


                                      S-30
<PAGE>

will be registrable, and Preferred Securities will be exchangeable for Preferred
Securities of other denominations of a like aggregate liquidation amount, at the
corporate trust office of the Property  Trustee in New York, New York;  provided
that payment of distributions  may be made at the option of the Regular Trustees
on behalf of the Trust by check  mailed to the address of the  persons  entitled
thereto and that the payment on redemption of any Preferred  Securities  will be
made only upon surrender of such Preferred Securities to the Property Trustee.

        or one of its  affiliates  will act as registrar and transfer  agent for
the Preferred Securities. will also act as paying agent and, with the consent of
the Regular Trustees, may designate additional paying agents.

       Registration  of  transfers  of  Preferred  Securities  will be  effected
without  charge by or on behalf of the Trust,  but upon payment (with the giving
of such indemnity as the Trust or the Company may require) in respect of any tax
or other governmental charges that may be imposed in relation to it.

       The Trust will not be required to register or cause to be registered  the
transfer of  Preferred  Securities  after such  Preferred  Securities  have been
called for redemption.


INFORMATION CONCERNING THE PROPERTY TRUSTEE

       The  Property  Trustee,  prior to a  default  with  respect  to the Trust
Securities, undertakes to perform only such duties as are specifically set forth
in the Declaration and, after default, shall exercise the same degree of care as
a prudent  individual  would  exercise in the conduct of his or her own affairs.
Subject  to such  provision,  the  Property  Trustee is under no  obligation  to
exercise any of the powers vested in it by the Declaration at the request of any
holder of Preferred  Securities,  unless  offered  reasonable  indemnity by such
holder  against  the costs,  expenses  and  liabilities  which might be incurred
thereby. The Property Trustee is not required to expend or risk its own funds or
otherwise incur personal financial liability in the performance of its duties if
the Property Trustee reasonably believes that repayment or adequate indemnity is
not reasonably assured to it.

       The Company and certain of its affiliates  maintain a deposit account and
banking relationship with the Property Trustee.


GOVERNING LAW

       The  Declaration  and the Preferred  Securities  will be governed by, and
construed in accordance with, the internal laws of the State of Delaware.


MISCELLANEOUS

       The Regular  Trustees are  authorized and directed to take such action as
they  deem  reasonable  in order  that the  Trust  will not be  deemed  to be an
"investment  company"  required to be registered  under the 1940 Act or that the
Trust will not be classified for United States federal income tax purposes as an
association  taxable as a corporation or a partnership  and will be treated as a
grantor trust for United States federal income tax purposes. In this connection,
the Regular Trustees are authorized to take any action,  not  inconsistent  with
applicable  law, the certificate of trust or the  Declaration,  that the Regular
Trustees  determine  in their  discretion  to be  reasonable  and  necessary  or
desirable for such  purposes,  as long as such action does not adversely  affect
the interests of holders of the Trust Securities.

       The  Company  and the  Regular  Trustees  on behalf of the Trust  will be
required to provide to the Property Trustee annually a certificate as to whether
or not the Company and the Trust,  respectively,  is in compliance  with all the
conditions and covenants under the Declaration.

                          DESCRIPTION OF THE GUARANTEE


       Pursuant to the Preferred Securities Guarantee,  AES will irrevocably and
unconditionally  agree, to the extent set forth therein,  to pay in full, to the
holders of the Preferred  Securities issued by the Trust, the Guarantee Payments
(as defined in the  accompanying  prospectus)  (except to the extent paid by the
Trust),  as and  when  due,  regardless  of any  defense,  right of  set-off  or
counterclaim  which the Trust may have or assert.  The  Company's  obligation to
make a Guarantee  Payment may be  satisfied  by direct  payment of the  required
amounts by the Company to the holders of Preferred  Securities or by causing the
Trust to pay such amounts to such holders.  The Preferred  Securities  Guarantee
will be qualified as an indenture  under the Trust  Indenture  Act. The Property
Trustee will act as indenture trustee under the Preferred  Securities  Guarantee
(the "Guarantee Trustee").  The terms of the Preferred Securities Guarantee will
be those set forth in such Preferred Securities Guarantee and those made part of
such Preferred  Securities Guarantee by the Trustee Indenture Act. The Preferred
Securities  Guarantee  will be held by the Guarantee  Trustee for the benefit of
the holders of the Preferred Securities.  A summary description of the Preferred
Securities  Guarantee  appears in the accompanying  prospectus under the caption
"Description of the Preferred Securities Guarantees."


               DESCRIPTION OF THE JUNIOR SUBORDINATED DEBENTURES


       Set forth below is a description of the Junior Subordinated Debentures in
which the Trust will invest the proceeds from the issuance and sale of the Trust
Securities  and which will be deposited in the Trust as trust assets.  The terms
of the  Junior  Subordinated  Debentures  include  those  stated  in the  Junior
Subordinated Debt Trust Securities Indenture dated as of between the Company and
, as trustee (the "Indenture  Trustee"),  as  supplemented  by the  supplemental
indenture to be dated as of , 1999 between the Company and the Indenture Trustee
(as so  supplemented,  the  "Indenture"),  forms of  which  have  been  filed as
exhibits to the Registration Statement of which this prospectus supplement forms
a part,  and those made part of the Indenture by the Trust  Indenture  Act. This
description  supplements  the description of the general terms and provisions of
the Junior Subordinated Debt Securities set forth in the accompanying prospectus
under  the  caption   "Description  of  the  Junior   Subordinated   Debt  Trust
Securities."  The following  description  does not purport to be complete and is
qualified in its entirety by reference to the Indenture and the Trust  Indenture
Act.  Whenever  particular  provisions  or defined  terms in the  Indenture  are
referred  to herein,  such  provisions  or  defined  terms are  incorporated  by
reference herein.

       The  Indenture  does  not  limit  the  aggregate   principal   amount  of
indebtedness   which  may  be  issued   thereunder   and  provides  that  Junior
Subordinated  Debentures  may be issued  thereunder  from time to time in one or
more series (collectively, together with the Junior Subordinated Debentures, the
"Subordinated  Debentures").  The Junior  Subordinated  Debentures  constitute a
separate series under the Indenture.

       Under  certain  circumstances  involving  the  dissolution  of  the Trust
following  the occurrence of a Special Event, Junior Subordinated Debentures may
be  distributed  to  the  holders  of the Trust Securities in liquidation of the
Trust.  See "Description of the Preferred Securities -- Special Event Redemption
or Distribution."


GENERAL

       The  Junior   Subordinated   Debentures   are   unsecured,   subordinated
obligations of the Company,  limited in aggregate  principal amount to an amount
equal  to  the  sum  of (1)  the  stated  liquidation  amount  of the  Preferred
Securities  issued by the Trust and (2) the proceeds  received by the Trust upon
issuance of the Common Securities to the Company (which proceeds will be used to
purchase an equal principal amount of Junior Subordinated Debentures).


                                      S-32
<PAGE>

       The entire  principal amount of the Junior  Subordinated  Debentures will
become due and payable,  together with any accrued and unpaid interest  thereon,
on , 2029.  The Junior  Subordinated  Debentures  are not subject to any sinking
fund.

       If Junior Subordinated Debentures are distributed to holders of Preferred
Securities in dissolution of the Trust, such Junior Subordinated Debentures will
initially  be issued as a Global  Security  (as  defined  below).  As  described
herein, under certain limited circumstances,  Junior Subordinated Debentures may
be  issued  in  certificated  form  in  exchange  for  a  Global  Security.  See
"Book-Entry  and  Settlement"  below.  In the  event  that  Junior  Subordinated
Debentures are issued in certificated form, such Junior Subordinated  Debentures
will  be in  denominations  of $50 and  integral  multiples  thereof  and may be
transferred  or exchanged  at the offices  described  below.  Payments on Junior
Subordinated  Debentures  issued  as a Global  Security  will be made to DTC,  a
successor  depositary  or, in the event that no  depositary is used, to a paying
agent for the Junior Subordinated Debentures.

       In  the  event  that  Junior   Subordinated   Debentures  are  issued  in
certificated  form,  payments of  principal  and interest  will be payable,  the
transfer of the Junior Subordinated  Debentures will be registrable,  and Junior
Subordinated  Debentures will be exchangeable for Junior Subordinated Debentures
of other  denominations of a like aggregate  principal  amount, at the corporate
trust office of the  Indenture  Trustee in provided that payment of interest may
be made at the  option of the  Company  by check  mailed to the  address  of the
persons  entitled  thereto and that the payment of principal with respect to any
Junior  Subordinated  Debenture  will be made only upon surrender of such Junior
Subordinated Debenture to the Indenture Trustee.

       If the Junior  Subordinated  Debentures are distributed to the holders of
Preferred Securities upon the dissolution of the Trust, the Company will use its
best efforts to list the Junior  Subordinated  Debentures on the NYSE or on such
other exchange on which the Preferred Securities are then listed.

OPTIONAL REDEMPTION

       Except as provided below, the Junior  Subordinated  Debentures may not be
redeemed  prior to , 2002.  AES  shall  have the  right  to  redeem  the  Junior
Subordinated Debentures, in whole or in part, from time to time, on or after
    ,  2002,  upon  not  less  than  30  nor  more  than  60 days notice, at the
following  prices  (expressed  as  percentages  of  the  principal amount of the
Junior  Subordinated  Debentures)  together  with  accrued  and unpaid interest,
including  Compounded  Interest  to,  but  excluding,  the  redemption  date, if
redeemed during the 12-month period beginning     :

and 100% if redeemed on or after     , 2007.

       If the  Junior  Subordinated  Debentures  are  redeemed  on any  Interest
Payment Date (as defined below), accrued and unpaid interest shall be payable to
holders of record on the relevant record date.

       So long as the corresponding  Preferred  Securities are outstanding,  the
proceeds from the redemption of any Junior Subordinated  Debentures will be used
to redeem Preferred Securities.

       The  Company  will also have the right to redeem the Junior  Subordinated
Debentures at any time upon the occurrence of a Tax Event if certain  conditions
are met as described under  "Description of the Preferred  Securities -- Special
Event Redemption or Distribution."

       The Company may not redeem any Junior Subordinated  Debentures unless all
accrued and unpaid interest thereon,  including  Compounded  Interest,  has been
paid for all quarterly periods  terminating on or prior to the date of notice of
redemption.

       If the  Company  gives a  notice  of  redemption  in  respect  of  Junior
Subordinated Debentures (which notice will be irrevocable), then, by 12:00


                                      S-33
<PAGE>

noon,  New York City time,  on the  redemption  date,  the Company  will deposit
irrevocably  with the Indenture  Trustee funds  sufficient to pay the applicable
Redemption  Price and will give  irrevocable  instructions  and authority to pay
such Redemption Price to the holders of the Junior Subordinated  Debentures.  If
notice of redemption shall have been given and funds deposited as required, then
upon the date of such  deposit,  interest  will  cease to accrue  on the  Junior
Subordinated   Debentures  called  for  redemption,   such  Junior  Subordinated
Debentures  will no longer be deemed to be outstanding and all rights of holders
of such Junior  Subordinated  Debentures  so called for  redemption  will cease,
except  the right of the  holders  of such  Junior  Subordinated  Debentures  to
receive the applicable Redemption Price, but without interest on such Redemption
Price. If any date fixed for redemption of Junior Subordinated Debentures is not
a Business Day, then payment of the  Redemption  Price payable on such date will
be made on the next  succeeding  day that is a  Business  Day (and  without  any
interest or other  payment in respect of any such delay)  except  that,  if such
Business Day falls in the next calendar  year,  such payment will be made on the
immediately  preceding Business Day, in each case with the same force and effect
as if made on such date fixed for redemption.  If the Company fails to repay the
Junior  Subordinated   Debentures  on  maturity  or  the  date  fixed  for  this
redemption,  or if  payment  of  the  Redemption  Price  in  respect  of  Junior
Subordinated  Debentures is  improperly  withheld or refused and not paid by the
Company,  interest  on such  Junior  Subordinated  Debentures  will  continue to
accrue,  from the original redemption date to the date of payment, in which case
the actual  payment date will be considered  the date fixed for  redemption  for
purposes of calculating  the applicable  Redemption  Price. If fewer than all of
the Junior Subordinated  Debentures are to be redeemed,  the Junior Subordinated
Debentures to be redeemed  shall be selected by lot or pro rata or in some other
equitable manner determined by the Indenture Trustee.

       In the event of any redemption in part, the Company shall not be required
to (1) issue,  register  the  transfer  of or exchange  any Junior  Subordinated
Debentures  during a period  beginning at the opening of 15 business days before
any selection for redemption of Junior Subordinated Debentures and ending at the
close  of  business  on the  earliest  date on  which  the  relevant  notice  of
redemption  is deemed to have been given to all  holders of Junior  Subordinated
Debentures  to be redeemed  and (2)  register  the  transfer of or exchange  any
Junior Subordinated Debentures so selected for redemption,  in whole or in part,
except  the  unredeemed  portion  of any Junior  Subordinated  Debentures  being
redeemed in part.


INTEREST

       The  Junior  Subordinated  Debentures  will  bear interest at the rate of
    %  per annum from      , 1999. Interest will be payable on    ,    ,     and
     of each year (each, an "Interest  Payment Date"),  commencing on , 2000, to
the person in whose  name such  Junior  Subordinated  Debenture  is  registered,
subject to certain exceptions, at the close of business on the Business Day next
preceding such Interest Payment Date. In the event (i) the Preferred  Securities
do not  continue  to  remain  in  book-entry  only  form or  (ii)  if  following
distribution  of  the  Junior  Subordinated   Debentures  to  holders  of  Trust
Securities upon dissolution of the Trust as described under  "Description of the
Preferred  Securities"  above,  the  Junior  Subordinated  Debentures  shall not
continue to remain in book-entry  only form, the relevant  record date will be .
Interest  payable on any Junior  Subordinated  Debenture  that is not punctually
paid or duly provided for on any Interest  Payment Date will forthwith  cease to
be payable to the person in whose name such  Junior  Subordinated  Debenture  is
registered on the relevant record date, and such defaulted interest will instead
be payable to the person in whose name such  Junior  Subordinated  Debenture  is
registered  on the special  record date or other  specified  date  determined in
accordance  with the Indenture;  provided,  however,  that interest shall not be
considered payable by the Company on any Interest Payment Date falling within an
Extension  Period  unless  the  Company  has  elected  to make a full or partial
payment  of  interest  accrued  on the Junior  Subordinated  Debentures  on such
Interest Payment Date.

       The  amount  of  interest  payable for any period will be computed on the
basis of a 360-day year of twelve 30 day months. If any


                                      S-34
<PAGE>

date on which interest is payable on the Junior Subordinated Debentures is not a
Business Day, then payment of the interest  payable on such date will be made on
the next  succeeding  day that is a Business  Day (and  without any  interest or
other  payment in respect of any such delay),  except that, if such Business Day
is in the next  succeeding  calendar  year,  such  payment  shall be made on the
immediately  preceding Business Day, in each case with the same force and effect
as if made on such date.


OPTION TO EXTEND INTEREST PAYMENT PERIOD

       So long as the Company shall not be in default in the payment of interest
on the  Junior  Subordinated  Debentures,  the  Company  shall have the right to
extend the interest  payment period from time to time for a period not exceeding
20 consecutive quarters.  The Company has no current intention of exercising its
right to extend an interest payment period. No interest shall be due and payable
during an  Extension  Period,  except at the end thereof.  During any  Extension
Period,  the  Company  shall not  declare  or pay any  dividends  on, or redeem,
purchase, acquire or make a distribution or liquidation payment with respect to,
any of its common stock or preferred  stock or make any guarantee  payments with
respect  thereto;  provided that the foregoing will not apply to stock dividends
payable in Common Stock paid by the  Company.  Prior to the  termination  of any
such  Extension  Period,  the Company may further  extend the  interest  payment
period;  provided that such Extension Period together with all such previous and
further  extensions  thereof  may not exceed 20  consecutive  quarters or extend
beyond the  maturity  of the Junior  Subordinated  Debentures.  On the  Interest
Payment Date  occurring at the end of each Extension  Period,  the Company shall
pay to the  holders of Junior  Subordinated  Debentures  of record on the record
date for such Interest Payment Date (regardless of who the holders of record may
have been on other  dates  during the  Extension  Period) all accrued and unpaid
interest on the Junior Subordinated  Debentures,  together with interest thereon
at the rate  specified  for the  Junior  Subordinated  Debentures  to the extent
permitted by applicable law, compounded  quarterly.  Upon the termination of any
Extension  Period and the  payment of all  amounts  then due,  the  Company  may
commence a new Extension Period, subject to the above requirements.  The Company
may also prepay at any time all or any portion of the interest accrued during an
Extension  Period.  Consequently,  there could be multiple  Extension Periods of
varying lengths throughout the term of the Junior Subordinated  Debentures,  not
to exceed 20  consecutive  quarters;  provided,  that no such  period may extend
beyond the stated maturity of the Junior Subordinated Debentures. The failure by
the Company to make  interest  payments  during an  Extension  Period  would not
constitute a default or an event of default under the Indenture or the Company's
currently outstanding indebtedness.

       If  the  Property  Trustee  shall  be  the  sole  holder  of  the  Junior
Subordinated  Debentures,  the Company shall give the Property Trustee notice of
its selection of such Extension  Period one Business Day prior to the earlier of
(1) the date the  distributions  on the Preferred  Securities are payable or (2)
the date the Trust is required  to give  notice to the NYSE or other  applicable
self-regulatory  organization  or to holders of the Preferred  Securities of the
record  date or the date such  distribution  is  payable.  The Trust  shall give
notice of the Company's selection of such Extension Period to the holders of the
Preferred Securities.

       If Junior  Subordinated  Debentures  have been  distributed to holders of
Trust Securities,  the Company shall give the holders of the Junior Subordinated
Debentures  notice of its selection of such  Extension  Period ten Business Days
prior to the earlier of (1) the next succeeding Interest Payment Date or (2) the
date  the  Company  is  required  to give  notice  to the  NYSE  (if the  Junior
Subordinated   Debentures   are  then  listed   thereon)  or  other   applicable
self-regulatory organization or to holders of the Junior Subordinated Debentures
of the record or payment date of such related interest payment.


ADDITIONAL INTEREST

       If at any time the Trust  shall be  required  to pay any  taxes,  duties,
assessments or governmental  charges of whatever nature (other than  withholding
taxes) imposed by the United States, or any other taxing authority, then, in any
such case, AES will pay as additional  interest  ("Additional  Interest") on the
Junior  Subordinated  Debentures such additional amounts as shall be required so
that the net amounts received and retained by the Trust


                                      S-35
<PAGE>

after paying any such taxes,  duties,  assessments or other governmental charges
will be equal to the amounts the Trust  would have  received  had no such taxes,
duties, assessments or other governmental charges been imposed.

CONVERSION OF THE JUNIOR SUBORDINATED DEBENTURES

       The Junior  Subordinated  Debentures are convertible into common stock at
the  option of the  holders of the Junior  Subordinated  Debentures  at any time
prior to the close of business on , 2029 (or, in the case of Junior Subordinated
Debentures  called for  redemption,  the close of business on the  Business  Day
prior to the  Redemption  Date) at the Initial  Conversion  Price subject to the
conversion  price  adjustments  described  under  "Description  of the Preferred
Securities  --  Conversion  Rights." The Trust has agreed not to convert  Junior
Subordinated  Debentures  held by it except  pursuant to a notice of  conversion
delivered  to the  Conversion  Agent by a holder of Preferred  Securities.  Upon
surrender of a Preferred Securities to the Conversion Agent for conversion,  the
Trust will distribute Junior Subordinated  Debentures to the Conversion Agent on
behalf of the holder of the Preferred  Securities  so  converted,  whereupon the
Conversion  Agent will convert  such Junior  Subordinated  Debentures  to common
stock on behalf of such  holder.  AES's  delivery  to the  holders of the Junior
Subordinated  Debentures  (through the Conversion  Agent) of the fixed number of
shares  of common  stock  into  which the  Junior  Subordinated  Debentures  are
convertible  (together  with the cash  payment,  if any,  in lieu of  fractional
shares)  will be deemed to satisfy the  obligation  of AES to pay the  principal
amount of the Junior Subordinated  Debentures so converted,  and the accrued and
unpaid interest  thereon  attributable to the period from the last date to which
interest has been paid or duly  provided  for;  provided,  however,  that if any
Junior  Subordinated  Debenture is converted  after a record date for payment of
interest, the interest payable on the related Interest Payment Date with respect
to such Junior  Subordinated  Debenture  shall be paid to the Trust  (which will
distribute  such  interest to the  converting  holder) or other holder of Junior
Subordinated Debentures, as the case may be, despite such conversion.


COMPOUNDED INTEREST

       Payments of  Compounded  Interest on the Junior  Subordinated  Debentures
held by the Trust will make funds available to pay any interest on distributions
in arrears in respect of the Preferred Securities pursuant to the terms thereof.

BOOK-ENTRY AND SETTLEMENT

       If any  Junior  Subordinated  Debentures  are  distributed  to holders of
Preferred  Securities  (see  "Description  of the Preferred  Securities"),  such
Junior Subordinated  Debentures will be issued in the form of one or more global
certificates (each a "Global Security") registered in the name of the Depositary
or its nominee.  Except under the limited circumstances  described below, Junior
Subordinated   Debentures  represented  by  the  Global  Security  will  not  be
exchangeable  for, and will not  otherwise be issuable as,  Junior  Subordinated
Debentures in definitive form. The Global Securities  described above may not be
transferred  except by the  Depositary  to a nominee of the  Depositary  or by a
nominee of the Depositary to the Depositary or another nominee of the Depositary
or to a successor Depositary or its nominee.

       The  laws  of some  jurisdictions  require  that  certain  purchasers  of
securities take physical  delivery of such  securities in definitive  form. Such
laws may impair the ability to transfer  beneficial  interests  in such a Global
Security.

       Except as provided below, owners of beneficial interests in such a Global
Security  will  not  be  entitled  to  receive   physical   delivery  of  Junior
Subordinated  Debentures  in  definitive  form and will  not be  considered  the
holders (as defined in the Trust  Indenture)  thereof for any purpose  under the
Indenture,  and no Global Security  representing Junior Subordinated  Debentures
shall be exchangeable,  except for another Global Security of like  denomination
and tenor to be registered in the name of the  Depositary or its nominee or to a
successor  Depositary or its nominee.  Accordingly,  each Beneficial  Owner must
rely on the procedures of the Depositary or if such person is not a Participant,
on the procedures of the Participant through which such person owns its interest
to  exercise  any  rights  of a holder  under  the  Trust  Indenture.  If Junior
Subordinated  Debentures are distributed to holder of Preferred Securities,  DTC
will act as securities depositary for the Junior Subordinated Debentures.

       For a description of DTC and DTC's book-entry system, see "Description of
the Preferred Securities -- Book-Entry Only Issuance


                                      S-36
<PAGE>

- -- The Depository Trust Company." As of the date of this prospectus  Supplement,
the description  herein of DTC's  book-entry  system and DTC's practices as they
relate to  purchases,  transfers,  notices  and  payments  with  respect  to the
Preferred  Securities  apply in all  material  respects to any debt  obligations
represented  by one or more  Global  Securities  held by DTC.  The  Company  may
appoint a successor to DTC or any successor  depositary in the event DTC or such
successor  depositary is unable or unwilling to continue as a depository for the
Global Securities.

       None of the  Company,  the  Indenture  Trustee,  any paying agent and any
other agent of the Company or the Indenture Trustee will have any responsibility
or  liability  for any aspect of the records  relating  to or  payments  made on
account of beneficial  ownership  interests in a Global Security for such Junior
Subordinated Debentures or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interests.

       A  Global  Security  shall  be  exchangeable   for  Junior   Subordinated
Debentures  registered in the names of persons other than the  depositary or its
nominee only if (1) the Depositary  notifies the Company that it is unwilling or
unable to continue as a  depositary  for such Global  Security  and no successor
depositary shall have been appointed; (2) the Depositary, at any time, ceases to
be a  clearing  agency  registered  under  the  Exchange  Act at which  time the
Depositary  is required to be so  registered  to act as such  depositary  and no
successor  depositary  shall have been appointed;  (3) the Company,  in its sole
discretion,  determines that such Global Security shall be so  exchangeable;  or
(4) there shall have occurred an Indenture Event of Default with respect to such
Junior  Subordinated  Debentures.  Any  Global  Security  that  is  exchangeable
pursuant to the preceding sentence shall be exchangeable for Junior Subordinated
Debentures  registered  in such  names as the  Depositary  shall  direct.  It is
expected that such  instructions  will be based upon directions  received by the
Depositary  from its  Participants  with  respect  to  ownership  of  beneficial
interests in such Global Security.


           RELATIONSHIP BETWEEN THE PREFERRED SECURITIES, THE JUNIOR
         SUBORDINATED DEBENTURES AND THE PREFERRED SECURITIES GUARANTEE


       As set forth in the Declaration, the Trust exists for the sole purpose of
(1) issuing the Trust Securities  evidencing  undivided  beneficial interests in
the assets of the Trust,  and investing the proceeds from such issuance and sale
in the Junior Subordinated  Debentures and (2) engaging in such other activities
as are necessary and incidental thereto.

       As long as payments of interest  and other  payments are made when due on
the Junior  Subordinated  Debentures,  such payments will be sufficient to cover
distributions  and other  payments  due on the  Preferred  Securities  primarily
because (1) the aggregate  principal  amount of Junior  Subordinated  Debentures
held  as  trust  assets  will  be  equal  to the  sum of  the  aggregate  stated
liquidation amount of the Preferred  Securities and the proceeds received by the
Trust upon issuance of the Common  Securities  to the Company;  (2) the interest
rate and interest and other payment dates on the Junior Subordinated  Debentures
will match the  distribution  rate and  distribution and other payment dates for
the Preferred  Securities;  (3) the Declaration  provides that the Company shall
pay for all  debts  and  obligations  (other  than  with  respect  to the  Trust
Securities) and all costs and expenses of the Trust, including any taxes and all
costs and expenses with respect thereto,  to which the Trust may become subject,
except for United States  withholding  taxes;  and (4) the  Declaration  further
provides  that the  Trustees  shall not cause or permit the Trust,  among  other
things,  to engage  in any  activity  that is not  consistent  with the  limited
purposes of the Trust. With respect to clause (5) above,  however,  no assurance
can be given that the Company will have sufficient resources to enable it to pay
such debts, obligations, costs and expenses on behalf of the Trust.

       Payments  of  distributions  and  other  payments  due on  the  Preferred
Securities are  guaranteed by the Company on a subordinated  basis as and to the
extent set forth under "Description of the Preferred  Securities  Guarantees" in
the  accompanying  prospectus.  If the Company  does not make  interest or other
payments on the Junior Subordinated


                                      S-37
<PAGE>

Debentures,  the Trust  will not make  distributions  or other  payments  on the
Preferred  Securities.  Under the Declaration,  if and to the extent the Company
does make interest or other payments on the Junior Subordinated Debentures,  the
Property  Trustee is obligated to make  distributions  or other  payments on the
Preferred  Securities.   The  Preferred  Securities  Guarantee  is  a  full  and
unconditional  guarantee from the time of issuance of the Preferred  Securities,
but the Preferred  Securities  Guarantee covers distributions and other payments
on the Preferred  Securities only if and to the extent that the Company has made
a payment  to the  Property  Trustee  of  interest  or  principal  on the Junior
Subordinated Debentures deposited in the Trust as trust assets.

       The Property  Trustee will have the Power to exercise all rights,  powers
and  privileges  under the  Indenture  with  respect to the Junior  Subordinated
Debentures,  including  its  rights  as the  holder of the  Junior  Subordinated
Debentures to enforce the Company's  obligations  under the Junior  Subordinated
Debentures upon the occurrence of an Indenture  Event of Default,  and will also
have the right to enforce the  Preferred  Securities  Guarantee on behalf of the
holders of the  Preferred  Securities.  In  addition,  the holders of at least a
majority in liquidation  amount of the Preferred  Securities will have the right
to direct  the  Property  Trustee  with  respect to  certain  matters  under the
Declaration  and the Preferred  Securities  Guarantee.  If the Property  Trustee
fails to enforce its rights  under the Trust  Indenture  any holder of Preferred
Securities may, after a period of 30 days has elapsed from such holder's written
request to the  Property  Trustee  to enforce  such  rights,  institute  a legal
proceeding  against the Company to enforce such rights.  If the Property Trustee
fails to enforce the Preferred Securities Guarantee,  to the extent permitted by
applicable  law,  any  holder of  Preferred  Securities  may  institute  a legal
proceeding directly against the Company to enforce the Property Trustee's rights
under the Preferred Securities Guarantee.  Notwithstanding the foregoing, if the
Company has failed to make a guarantee payment, a holder of Preferred Securities
may directly  institute a proceeding  against the Company for enforcement of the
Preferred  Securities  Guarantee  for  such  payment.  See  "Description  of the
Preferred Securities" and "Description of the Guarantee" herein and "Description
of the Preferred  Securities  Guarantees  -- Status of the Preferred  Securities
Guarantees" in the accompanying prospectus.

       The above mechanisms and obligations,  taken together, provide a full and
unconditional  guarantee  by the  Company  of  payments  due  on  the  Preferred
Securities.


                        CERTAIN FEDERAL TAX CONSEQUENCES


In the opinion of Davis Polk &  Wardwell,  counsel to the Company and the Trust,
the following are the material United States federal income tax  consequences of
the ownership and disposition of Preferred Securities.  Unless otherwise stated,
this summary  deals only with  Preferred  Securities  held as capital  assets by
holders who acquire the Preferred Securities upon original issuance at the price
indicated  on the  cover of this  prospectus  supplement.  It does not deal with
special  classes of holders,  such as dealers in securities or currencies,  life
insurance companies,  persons holding Preferred Securities as part of a straddle
or as part of a hedging or conversion  transaction,  or persons whose functional
currency is not the United States dollar.  This summary is based on the Internal
Revenue Code of 1986, as amended (the "Code"),  Treasury Regulations  thereunder
and administrative and judicial  interpretations  thereof as of the date hereof,
all of which are subject to change (possibly on a retroactive basis).

Investors  are advised to consult  their tax  advisors  as to the United  States
federal income tax  consequences  of the ownership and  disposition of preferred
securities in light of their particular circumstances,  as well as the effect of
any state, local or other tax laws.


CLASSIFICATION OF THE JUNIOR SUBORDINATED DEBENTURES

The Company intends to take the position that the Junior Subordinated Debentures
will be classified for United States federal income tax purposes as indebtedness
under current law. No assurance can be given,  however,  that this position will
not be challenged by the Internal Revenue Service ("IRS"). The remainder of this


                                      S-38
<PAGE>

discussion  assumes that the Junior  Subordinated  Debentures will be classified
for United States  federal income tax purposes as  indebtedness  of the Company,
and, by acceptance of a Preferred  Security,  each holder covenants to treat the
Junior Subordinated  Debentures as indebtedness and the Preferred  Securities as
evidence of an indirect beneficial ownership interest in the Junior Subordinated
Debentures.


CLASSIFICATION OF THE TRUST

In  connection  with the  issuance  of the  Preferred  Securities,  Davis Polk &
Wardwell,  counsel  to the  Company  and the  Trust,  will  render  its  opinion
generally to the effect that,  assuming  full  compliance  with the terms of the
Declaration,  the Trust will be classified  for United States federal income tax
purposes as a grantor trust and not as an association  taxable as a corporation.
Accordingly, each holder of Preferred Securities will be considered the owner of
a pro rata portion of the Junior  Subordinated  Debentures held by the Trust and
will be required to include in gross income its pro rata share of income accrued
on the Junior Subordinated Debentures.


ACCRUAL OF ORIGINAL ISSUE DISCOUNT

Because we have the right to extend the  interest  payment  period on the Junior
Subordinated  Debentures,  all of the  stated  interest  payments  on the Junior
Subordinated  Debentures will be treated as "original  issue discount"  ("OID").
Accordingly,  each holder of  Preferred  Securities,  including  a taxpayer  who
otherwise  uses the cash method of  accounting,  will be required to include its
pro rata  share of OID on the  Junior  Subordinated  Debentures  in income as it
accrues,  in accordance  with a constant  yield method based on a compounding of
interest,  before the receipt of cash distributions on the Preferred Securities.
Generally,  all of a holder's taxable interest income with respect to the Junior
Subordinated Debentures will be accounted for as OID and actual distributions of
stated interest will not be separately  reported as taxable  income.  So long as
the interest payment period is not extended,  cash  distributions  received by a
holder for any quarterly  interest period (assuming no disposition  prior to the
record date for such  distribution)  will  generally  equal the sum of the daily
accruals of income for such quarterly interest period.

The  total  amount of  "original  issue  discount"  on the  Junior  Subordinated
Debentures  will equal the  difference  between the "issue  price" of the Junior
Subordinated  Debentures and their "stated redemption price at maturity." All of
the stated  interest  payments  on the Junior  Subordinated  Debentures  will be
includable in  determining  their  "stated  redemption  price at maturity."  The
"issue price" of each $50  principal  amount of Junior  Subordinated  Debentures
will be equal to the first price to the public at which a substantial  amount of
the Preferred Securities is sold for cash, which is expected to be $50.

A holder's  initial tax basis for its pro rata share of the Junior  Subordinated
Debentures  will be equal to its pro rata  share  of  their  "issue  price,"  as
defined above, and will be increased by OID accrued with respect to its pro rata
share of the Junior Subordinated  Debentures,  and reduced by the amount of cash
distributions  with respect  thereto.  No portion of the amounts received on the
Preferred Securities will be eligible for the dividends received deduction.



POTENTIAL EXTENSION OF PAYMENT PERIOD ON THE JUNIOR SUBORDINATED DEBENTURES

Holders of  Preferred  Securities  will  continue to accrue OID with  respect to
their pro rata share of the Junior  Subordinated  Debentures  during an extended
interest  payment  period.  A holder who  disposes of the  Preferred  Securities
during an extended interest period may suffer a loss because the market value of
the Preferred  Securities  will likely fall if AES exercises its option to defer
payments of interest on the Junior Subordinated Debentures.  See "Disposition of
the Preferred Securities" below. Furthermore,  the market value of the Preferred
Securities may not reflect the  accumulated  distributions  that will be paid at
the end of the extended  interest  period,  and a holder who sells the Preferred
Securities  during the  extended  interest  period will not receive from AES any
cash  related to the  interest  income the holder  accrued  and  included in its
taxable  income under the OID rule (because that cash will be paid to the holder
of record at the end of the extended interest period).


DISTRIBUTION   OF   JUNIOR  SUBORDINATED  DEBENTURES  TO  HOLDERS  OF  PREFERRED
SECURITIES

Under  current  law,  a  distribution  by  the  Trust of the Junior Subordinated
Debentures as


                                      S-39
<PAGE>

described under the caption  "Description of the Preferred Securities -- Special
Event  Redemption or  Distribution"  will be non-taxable  and will result in the
holder  receiving  directly  its  pro  rata  share  of the  Junior  Subordinated
Debentures  previously held indirectly  through the Trust, with a holding period
and tax basis equal to the holding period and adjusted tax basis such holder was
considered  to  have  had  in his  pro  rata  share  of  the  underlying  Junior
Subordinated Debentures prior to such distribution.

DISPOSITION OF THE PREFERRED SECURITIES

Upon  a  sale,  exchange  or  other  disposition  of  the  Preferred  Securities
(including  a  distribution  of  cash  in  redemption  of a  holder's  Preferred
Securities  upon redemption or repayment of the underlying  Junior  Subordinated
Debentures, but excluding the distribution of Junior Subordinated Debentures), a
holder will be  considered to have disposed of all or part of its pro rata share
of the Junior Subordinated Debentures,  and will recognize gain or loss equal to
the difference  between the amount realized and the holder's  adjusted tax basis
in its pro rata share of the underlying  Junior  Subordinated  Debentures deemed
disposed of. Such gain or loss will be capital gain or loss. Holders are advised
to consult  their tax  advisers  regarding  the  taxation  of capital  gains and
losses.

The  Preferred  Securities  may trade at a price that does not fully reflect the
value of accrued  but unpaid  interest  with  respect to the  underlying  Junior
Subordinated  Debentures.  A holder who  disposes  of its  Preferred  Securities
between record dates for payments of distributions  thereon will nevertheless be
required  to include  accrued  but unpaid  interest  on the Junior  Subordinated
Debentures  through the date of  disposition  in income as OID,  and to add such
amount to its adjusted tax basis in its pro rata share of the underlying  Junior
Subordinated  Debentures  deemed  disposed of.  Accordingly,  such a holder will
recognize a capital  loss to the extent the selling  price  (which may not fully
reflect  the value of accrued  but unpaid  interest)  is less than the  holder's
adjusted tax basis (which will include accrued but unpaid interest).  Subject to
certain limited exceptions,  capital losses cannot be applied to offset ordinary
income for United States federal income tax purposes.

CONVERSION OF PREFERRED SECURITIES TO AES COMMON STOCK

A holder of Preferred  Securities will not recognize  income,  gain or loss upon
the conversion through the Conversion Agent, of Junior  Subordinated  Debentures
into AES common stock. A holder of Preferred Securities will recognize gain upon
the receipt of cash in lieu of a  fractional  share of AES common stock equal to
the amount of cash  received  less such  holder's  tax basis in such  fractional
share.  Such holder's tax basis in the AES common stock received upon conversion
will  generally be equal to such holder's tax basis in the Preferred  Securities
delivered to the Conversion Agent for exchange,  less the basis allocated to any
fractional share for which cash is received. Such holder's holding period in the
AES common stock received upon  conversion  will generally  include the holder's
holding period of the Preferred Securities delivered to the Conversion Agent for
exchange,  except  possibly with respect to AES common stock received in respect
of any accrued but unpaid OID.


ADJUSTMENT OF CONVERSION PRICE

Treasury  Regulations  promulgated  under  section  305 of the Code would  treat
holders of Preferred  Securities as having received a constructive  distribution
from AES in certain events  pursuant to which the conversion  rate of the Junior
Subordinated  Debentures were adjusted.  Thus,  under certain  circumstances,  a
reduction in the  conversion  price for the Junior  Subordinated  Debentures may
result in deemed  dividend  income to holders  of  Preferred  Securities  to the
extent of the current or  accumulated  earnings  and profits of AES.  Holders of
Preferred  Securities are advised to consult their tax advisors as to the income
tax consequences of adjustments in the conversion rate of Preferred Securities.



INFORMATION REPORTING TO HOLDERS

The Trust will report the OID that  accrued  during the year with respect to the
Junior  Subordinated  Debentures,  and any gross proceeds  received by the Trust
from  the  retirement  or  redemption  of the  Junior  Subordinated  Debentures,
annually to the holders of record of the Preferred  Securities  and the IRS. The
Trust currently intends to deliver such reports to holders of record prior to


                                      S-40
<PAGE>

January 31 following each calendar year. It is anticipated that persons who hold
Preferred Securities as nominees for beneficial holders will report the required
tax information to beneficial holders on Form 1099.


BACKUP WITHHOLDING

Payments  made on, and  proceeds  from the sale of Preferred  Securities  may be
subject to a "backup"  withholding  tax of 31% unless the holder  complies  with
certain  identification  requirements.  Any withheld  amounts will  generally be
allowed as a credit  against  the  holder's  federal  income tax,  provided  the
required information is timely filed with the IRS.


UNITED STATES ALIEN HOLDERS

For  purposes  of  this  discussion,  a  "United  States  Alien  Holder"  is any
corporation,  individual, partnership, estate or trust that is, for U.S. federal
income tax purposes,  a foreign corporation,  a nonresident alien individual,  a
foreign partnership, or a non-resident fiduciary of a foreign estate or trust.

Payments on Preferred  Securities.  As discussed  above,  the Company intends to
take the position that the Junior Subordinated Debentures will be classified for
United States federal income tax purposes as  indebtedness  of AES under current
law. No assurance can be given,  however, that this position of the Company will
not be challenged by the IRS.

Assuming that the Junior Subordinated Debentures are classified for U.S. federal
income tax purposes as  indebtedness of AES, under present United States federal
income tax law,  payments by the Trust or any of its paying agents to any holder
of a  Preferred  Security  that is a United  States  Alien  Holder  would not be
subject to United  States  federal  withholding  tax;  provided,  that,  (a) the
beneficial owner of the Preferred Securities does not actually or constructively
own 10% or more of the total  combined  voting  power of all classes of stock of
AES entitled to vote,  (b) the beneficial  owner of the Preferred  Securities is
not a  controlled  foreign  corporation  that is  related to AES  through  stock
ownership,  and (c) either (1) the beneficial owner of the Preferred  Securities
certifies  on IRS form W-8 (or any  successor  form) to the Trust or its  agent,
under  penalties of perjury,  that it is not a U.S. person and provides its name
and address or (2) a securities clearing  organization,  bank or other financial
institution that holds customers' securities in the ordinary course of its trade
or business (a "Financial  Institution"),  and holds the Preferred Securities in
such capacity,  certifies to the Trust or its agent, under penalties of perjury,
that such  statement has been received from the  beneficial  owner by it or by a
Financial  Institution  between it and the  beneficial  owner and  furnishes the
Trust or its agent with a copy thereof.

No withholding  will apply to AES common stock received by a United States Alien
Holder of  Preferred  Securities  upon the  conversion  of  Junior  Subordinated
Debentures into AES common stock.  Under current  Treasury  Regulations,  backup
withholding  at a rate of 31% will not apply to  distributions  on the Preferred
Securities if the  certifications  discussed  above are made to the Trust or its
agent,  provided  in each case that the Trust or its agent does not have  actual
knowledge the payee is a U.S. person.

If the Junior  Subordinated  Debentures  were not  classified  for United States
federal income tax purposes as indebtedness of AES, payments by the Trust or any
of its paying  agents to any holder of a Preferred  Securities  that is a United
States Alien Holder would be subject to United States  withholding  tax at a 30%
rate (or a lower rate  prescribed  by an  applicable  tax  treaty).  Prospective
investors  that would be United  States Alien Holders  should  consult their tax
advisors concerning the possible application of these rules.

As discussed  above under "--  Adjustment  of Conversion  Price",  under certain
circumstances  a reduction in the conversion  price for the Junior  Subordinated
Debentures  may  result  in  deemed  dividend  income to  holders  of  Preferred
Securities to the extent of the current or  accumulated  earnings and profits of
AES. Any such deemed  dividend  income that arises after  December 31, 2000 with
respect to a United States Alien Holder of Preferred  Securities  generally will
be subject to withholding tax at a 30% rate or at a reduced rate as specified by
an applicable tax treaty. For additional information respecting the treatment of
such deemed  dividend  income,  please see the discussion  relating to dividends
paid after December 31,


                                      S-41
<PAGE>

2000 below,  under "-- United  States  Alien  Holders -- Dividends on AES Common
Stock."

Dividends on AES Common Stock.  Subject to the discussion below,  dividends paid
to a United States Alien Holder of AES common stock generally will be subject to
withholding  tax at a 30%  rate or such  lower  rate as may be  specified  by an
applicable income tax treaty.  For purposes of determining  whether tax is to be
withheld  at a 30% rate or at a  reduced  rate as  specified  by an  income  tax
treaty,  the Company ordinarily will presume that dividends paid before December
31,  2000 to an address  in a foreign  country  are paid to a  resident  of such
country, absent knowledge that such presumption is not warranted.

Under the Treasury  Regulations  applicable to dividends paid after December 31,
2000 (the "Final Regulations"),  to obtain a reduced rate of withholding under a
treaty,  a United States Alien Holder is generally be required to provide an IRS
form W-8 (or any successor  form)  certifying  such United States Alien Holder's
entitlement  to benefits  under a treaty.  The Final  Regulations  also  provide
special  rules  to  determine   whether,   for  purposes  of   determining   the
applicability  of a tax treaty,  dividends  paid to a United States Alien Holder
that is an entity  should be treated  as paid to the entity or those  holding an
interest in that entity.


Generally,  the Company must report to the IRS the amount of dividends paid, the
name and address of the recipient,  and the amount,  if any, of tax withheld.  A
similar report is sent to the holder.  Pursuant to tax treaties or certain other
agreements,  the IRS may make its reports  available to tax  authorities  in the
recipient's country of residence.


Sale or Exchange of Preferred  Securities or AES Common  Stock.  A United States
Alien Holder (other than certain U.S.  expatriates)  will not be subject to U.S.
federal income tax on gain realized on a sale,  exchange or other disposition of
the Preferred  Securities or AES common stock unless (i) the United States Alien
Holder is an  individual  who is present in the U.S. for 183 days or more in the
taxable year of disposition, and certain other conditions are satisfied; or (ii)
AES is or has been a "United States real property  holding  corporation"  within
the  meaning of section  897(c)(2)  of the Code during the shorter of the United
States Alien Holder's  holding period or the five year period ending on the date
of the sale,  exchange or other  disposition  and certain other  conditions  are
satisfied.


The  Company  believes  that it is  unlikely  that it is or will be treated as a
"United States real property holding  corporation" within the meaning of Section
897(c)(2) of the Code.  Even if AES is treated as a United  States real property
holding  corporation,  gain  realized  by a  United  States  Alien  Holder  on a
disposition  of Preferred  Securities or AES Common Stock will not be subject to
U.S.  federal income tax so long as (i) the United States Alien Holder is deemed
to have  beneficially  owned,  in the case of a disposition of AES Common Stock,
less  than  or  equal  to 5% of the  AES  Common  Stock  or,  in the  case  of a
disposition of Preferred  Securities,  less than or equal to 5% of the Preferred
Securities,  and (ii) the AES  common  stock and the  Preferred  Securities  are
currently  and will be, at the time of  disposition,  "regularly  traded"  on an
established  securities  market (within the meaning of Section  897(c)(3) of the
Code  and  the  temporary  Treasury  Regulations  thereunder.  There  can  be no
assurance  that AES Common  Stock or the  Preferred  Securities  qualify or will
continue to qualify as "regularly traded" on an established securities market.


Effectively  Connected  Income.  If a United  States  Alien  Holder of Preferred
Securities  or AES common  stock is engaged in a trade or business in the United
States,  and if original issue discount  accrued on the Preferred  Securities or
dividends on the common stock is effectively  connected with the conduct of such
trade or business,  the United  States Alien  Holder,  although  exempt from the
withholding tax on  distributions  on Preferred  Securities and dividends on AES
common stock,  will  generally be subject to regular United States income tax on
the original  issue discount and dividends and on any gain realized on the sale,
exchange or other disposition of Preferred Securities or AES common stock in the
same manner as if it were a United States person. Such a holder will be required
to provide to the Company with a properly executed IRS Form 4224 (or a successor
form) in order to claim an exemption from  withholding tax. On or after December
31, 2000, to comply with this requirement,  the United States Alien Holder needs
to also provide a valid United States taxpayer indentification


                                      S-42
<PAGE>

number.  In  addition,   if  such  United  States  Alien  Holder  is  a  foreign
corporation,  it may be subject to a branch profits tax equal to 30% (or a lower
rate prescribed by an applicable  treaty) of its effectively  connected earnings
and profits for the taxable year.

       Backup Withholding on Disposition of Preferred Securities.  Under current
United  States  federal  income  tax  law,  information   reporting  and  backup
withholding imposed at a rate of 31% will apply to the proceeds of a disposition
of Preferred  Securities effected by or through a U.S. office of a broker unless
the  disposing  holder  certifies  as  to  its  non-U.S.   status  or  otherwise
establishes  an  exemption.  Generally,  U.S.  information  reporting and backup
withholding  will not  apply to a  payment  of  disposition  proceeds  where the
transaction is effected outside the U.S. through a non-U.S. office of a non-U.S.
broker.  However,  U.S.  information  reporting  requirements  (but  not  backup
withholding)  will  apply  to  a  payment  of  disposition  proceeds  where  the
transaction  is effected  outside  the U.S. by or through an office  outside the
U.S. of a broker that is either (i) a U.S.  person,  (ii) a foreign person which
derives 50% or more of its gross income for certain  periods from the conduct of
a trade or business in the U.S.,  (iii) a "controlled  foreign  corporation" for
U.S.  federal  income tax  purposes,  or (iv) in the case of payments made after
December 31, 2000, a foreign  partnership with certain connections to the United
States, in each case unless the holder has documentary  evidence that the holder
is a Non-U.S.  Holder  and that  certain  conditions  are met or that the holder
otherwise establishes an exemption.


       Backup withholding is not an additional tax. Rather, the tax liability of
persons  subject  to backup  withholding  will be  reduced  by the amount of tax
withheld.  If  withholding  results in an  overpayment of taxes, a refund may be
obtained, provided that the required information is furnished to the IRS.


                              ERISA CONSIDERATIONS


GENERAL

A  fiduciary  of an employee  benefit  plan  subject of Title I of ERISA  should
consider  fiduciary  standards  under  ERISA in the  context  of the  particular
circumstances  of such plan before  authorizing  an  investment in the Preferred
Securities.  Such fiduciary  should  consider  whether the investment  satisfies
ERISA's  diversification  and  prudence  requirements,  whether  the  investment
constitutes  unauthorized  delegation  of  fiduciary  authority  and whether the
investment is in accordance  with the  documents and  instruments  governing the
plan.  In  addition,  ERISA and the Code  prohibit a wide range of  transactions
("Prohibited  Transactions")  involving the assets of a plan subject to ERISA or
the assets of an individual  retirement  account or plan subject to Section 4975
of the Code (hereinafter an "ERISA Plan") and persons who have certain specified
relationships  to the ERISA Plan  ("parties in interest,"  within the meaning of
ERISA,  and  "disqualified  persons,"  within the  meaning  of the  Code).  Such
transactions may require  "correction" and may cause the ERISA Plan fiduciary to
incur certain liabilities and the parties in interest or disqualified persons to
be subject to excise taxes.

The  acquisition  of  Preferred  Securities  by any person who is using for such
acquisition  the assets of an ERISA Plan shall  constitute a  representation  by
such person to AES that (1) if AES is a "party in interest"  or a  "disqualified
person" with respect to such ERISA Plan,  then such  security is being  acquired
pursuant to an exemption from the Prohibited  Transaction  rules under ERISA and
the Code, and (2) AES is not a "fiduciary,"  within the meaning of Section 3(21)
of ERISA and the regulations thereunder,  with respect to such person's interest
in the Preferred Securities or the Junior Subordinated Debentures.

Governmental  plans and certain  church plans (each as defined  under ERISA) are
not subject to the Prohibited  Transaction  rules. Such plans may,  however,  be
subject to federal,  state or local laws or  regulations  which may affect their
investment in the Preferred Securities.  Any fiduciary of such a governmental or
church  plan  considering  an  investment  in the  Preferred  Securities  should
determine the need for, and the  availability,  if  necessary,  of any exemptive
relief under such laws or regulations.

The  discussion  herein  of ERISA is general in nature and is not intended to be
all inclusive. Any fiduciary of an ERISA Plan, governmental


                                      S-43
<PAGE>

plan or church plan considering an investment in the Preferred Securities should
consult with its legal advisors regarding the consequences of such investment.


PROHIBITED TRANSACTIONS

AES may be a party in interest or a disqualified person with respect to an ERISA
Plan investing in the Preferred Securities,  and, therefore, such investments by
an ERISA Plan may give rise to a Prohibited  Transaction.  Consequently,  before
investing in the  Preferred  Securities,  any person who is, or who in acquiring
such  securities  is using the assets of, an ERISA Plan  should  determine  that
either  a  statutory  or  an   administrative   exemption  from  the  Prohibited
Transaction  rules discussed below or otherwise  available is applicable to such
person's investment in the Preferred Securities,  or that its investment in such
securities will not result in a Prohibited Transaction.

Certain statutory or administrative  exemptions from the Prohibited  Transaction
rules  under  ERISA  and the Code may be  available  to an ERISA  Plan  which is
investing in the Preferred  Securities.  Included  among these  exemptions  are:
Prohibited  Transaction Class Exemption ("PTCE") 90-1, regarding  investments by
insurance company pooled separate accounts; PTCE 91-38, regarding investments by
bank collective investment funds; PTCE 84-14, regarding transactions effected by
qualified  professional  asset  managers;  PTCE  96-23,  regarding  transactions
effected by in-house asset  managers;  or PTCE 95-60,  regarding  investments by
insurance company general accounts.


TRUST ASSETS AS "PLAN ASSETS"

The Department of Labor has issued final  regulations (the "Labor  Regulations")
as to what  constitutes  assets of an employee benefit plan ("plan asset") under
ERISA. The Labor Regulations provide that, as a general rule, when an ERISA Plan
acquires an equity  interest in an entity and such interest does not represent a
"publicly  offered  security"  nor a security  issued by an  investment  company
registered  under the  Investment  Company Act of 1940,  the ERISA Plan's assets
include  both the  equity  interest  and an  undivided  interest  in each of the
underlying assets of the entity, unless it is established either that the entity
in an operating  company or that equity  participation in the entity by "benefit
plan investors" is not "significant." For purposes of the Labor Regulations, the
Trust  will  not be an  investment  company  nor an  operating  company  and the
Preferred  Securities  will not  constitute a "publicly  offered  security."  As
discussed below, after resales pursuant to the shelf registration statement, the
Preferred  Securities may qualify as "publicly offered  securities" for purposes
of the Labor Regulations, but such result cannot be assured.

Under the Labor Regulations, equity participation by benefit plan investors will
not be considered  "significant" on any date only if, immediately after the most
recent  acquisition  of  Preferred  Securities,  the  aggregate  interest in the
Preferred Securities held by benefit plan investors will be less than 25% of the
value of the  Preferred  Securities.  Although  it is  possible  that the equity
participation  by benefit plan  investors on any date will not be  "significant"
for  purposes  of  the  Labor  Regulations,   such  result  cannot  be  assured.
Consequently,  if ERISA  Plans or  investors  using plan  assets of ERISA  plans
purchase  the  Preferred  Securities,  the Trust's  assets could be deemed to be
"plan  assets" of such ERISA Plan for purposes of the  fiduciary  responsibility
provisions  of ERISA and the Code.  Under ERISA,  any person who  exercises  any
authority or control  respecting  the management or disposition of the assets of
an ERISA Plan is considered  to be a fiduciary of such ERISA Plan.  For example,
the Property  Trustee could therefore become a fiduciary of the ERISA Plans that
invest in the  Preferred  Securities  and be  subject to the  general  fiduciary
requirements of ERISA in exercising its authority with respect to the management
of the assets of the Trust. However, the Property Trustee will have only limited
discretionary  authority  with respect to the Trust's  assets and the  remaining
functions and the responsibilities performed by the Property Trustee will be for
the most part  custodial  and  ministerial  in nature.  Inasmuch as the Property
Trustee or another person with authority or control respecting the management or
disposition of the Trust assets may become a fiduciary with respect to the ERISA
Plans that will  purchase  the  Preferred  Securities,  there may be an improper
delegation by such ERISA Plans of the responsibility to manage plan assets.

It  is  expected  that  Preferred  Securities will be distributed pursuant to an
effective registration


                                      S-44
<PAGE>

statement under the Securities Act and they may subsequently be registered under
the  Exchange  Act.  Preferred  Securities  may  qualify  as  "publicly  offered
securities" under the Labor Regulations if, in addition to such distribution and
registration,  they are also "widely held" and "freely  transferable." Under the
Labor Regulations,  a class of securities is "widely held" only if it is a class
of securities  that is owned by 100 or more investors  independent of the issuer
and of one another.  Although it is possible that after distribution pursuant to
the shelf registration statement the Preferred Securities will be "widely held,"
such result cannot be assured.  Whether a security is "freely  transferable" for
purposes of the Labor  Regulations is a factual question to be determined on the
basis  of all  relevant  facts  and  circumstances.  If after  the  distribution
pursuant to the shelf registration  statement,  the Preferred  Securities do not
qualify  as  "publicly  offered  securities,"  the "plan  asset"  considerations
discussed in the immediately preceding paragraph could continue to be applicable
in connection with the investment by ERISA Plans or investors' using plan assets
of ERISA Plans.

       Subject  to  the  terms  and  conditions  set  forth  in an  underwriting
agreement,  the underwriters named below have severally agreed to purchase,  and
AES and the Trust have agreed that the Trust will sell to each underwriter,  the

       The  underwriting   agreement   provides  that  the  obligations  of  the
underwriters to purchase the Preferred  Securities included in this offering are
subject to approval  of certain  legal  matters by counsel and to certain  other
conditions.  The  underwriters  are  obligated  to  take  and pay for all of the
Preferred  Securities  (other  than those  covered by the  overallotment  option
described below) if any are taken.


       The  underwriters  have advised us that they  propose  initially to offer
such Preferred  Securities to the public at the price to public set forth on the
cover page of this prospectus supplement. After the initial public offering, the
public offering price may be changed.


       AES has granted to the  underwriters  an option,  exercisable for 30 days
from  the  date  hereof,  to  purchase  up to an  additional  900,000  Preferred
Securities  at the price to public on the terms set forth on the cover page less
the  underwriting  discount  set  forth  on the  cover  page of this  prospectus
supplement. The underwriters may exercise such option to purchase solely for the
purpose  of  covering  overallotments,  if any,  made  in  connection  with  the
offering.

       AES and certain of its  directors  and  executive  officers  are agreeing
that, with certain exceptions  (including  issuances by AES as consideration for
acquisitions),  without the prior written consent of J.P. Morgan Securities Inc.
and Goldman, Sachs & Co., they will not, directly or indirectly,  offer to sell,
contract to sell, sell or otherwise  dispose of, or announce the offering of any
shares  of  common  stock or  securities  convertible  into or  exchangeable  or
exercisable  for shares of common stock,  for a period of 90 days after the date
of the underwriting agreement, provided that beginning 30 days after the date of
the underwriting  agreement such officers and directors may sell limited amounts
of shares per day up to a total of 500,000 shares (taken in the aggregate and as
a group).

       AES and the Trust have each agreed to indemnify the underwriters against,
or  contribute  to  payments  that the  underwriters  may be required to make in
respect of, certain liabilities,  including liabilities under the Securities Act
of 1933, as amended.

       The  underwriters  may  engage  in  stabilizing  transactions,  syndicate
covering  transactions  and penalty bids in  accordance  with Rule 104 under the
Securities  Exchange Act of 1934, as amended,  in connection  with the offering.
Stabilizing  transactions  permit bids to purchase the Preferred  Securities and
common stock so long as the stabilizing bids do not exceed a specified  maximum.
Syndicate covering transactions involve purchases of the Preferred Securities in
the open

market  following  completion  of the  offering  to cover all or a portion  of a
syndicate  short  position  created by the  underwriters  selling more Preferred
Securities in  connection  with the offering than they are committed to purchase
from  us.  In  addition,  the  underwriters  may  impose  "penalty  bids"  under
contractual  arrangements between the underwriters and dealers  participating in
the  offering  whereby  they  may  reclaim  from a dealer  participating  in the
offering  the  selling  concession  with  respect to  Preferred  Securities  are
distributed  in the offering but  subsequently  purchased for the account of the
underwriters  in the  open  market.  Such  stabilizing  transactions,  syndicate
covering  transactions  and penalty  bids may result in the  maintenance  of the
price of the Preferred  Securities  and common stock at a level above that which
might otherwise prevail in the open market.  None of the transactions  described
in  this  paragraph  is  required  and,  if  any  are  undertaken,  they  may be
discontinued at any time.

       Certain of the  underwriters  in this offering are acting as underwriters
in the offering of the common stock. In the ordinary course of the underwriters'
respective  businesses,  the  underwriters and their affiliates have engaged and
may engage in commercial and  investment  banking  transactions  with us and our

                              SUMMARY INFORMATION
                             QUESTIONS AND ANSWERS


       This  summary  provides  a  brief  overview  of the  key  aspects  of the
preferred  securities.  You should  carefully read this prospectus to understand
fully  the  terms  of the  preferred  securities  as well  as the tax and  other
considerations  that are important to you in making a decision  about whether to
invest in the  preferred  securities.  You should pay special  attention  to the
"Risk  Factors"  section  beginning  on page 5 of this  prospectus  to determine
whether an investment in the preferred securities is appropriate for you.


WHAT ARE THE PREFERRED SECURITIES?

       Each preferred security  represents an undivided  beneficial  interest in
the assets of the applicable AES Trust. Each preferred security will entitle the
holder to receive cash  distributions as described in the applicable  prospectus
supplement.


WHO ARE AES TRUSTS?

       The AES Trusts are Delaware  business  trusts.  Their  principal place of
business is c/o The AES Corporation, 1001 North 19th Street, Arlington, Virginia
22209, and its telephone number is (703) 522-1315.  All of the common securities
of the AES Trusts will be owned by the AES Corporation.  The AES Trusts will use
the proceeds from the sale of the preferred securities and the common securities
to buy a series of junior  subordinated  deferrable interest debentures from AES
with the same financial terms as the preferred securities.


WHO IS THE AES CORPORATION?

       We are a global  power  company,  with 104 power  plants in  operation or
under  construction,  87 of which are located outside of the United States.  The
mailing  address of our  principal  executive  office is 1001 North 19th Street,
Arlington,  Virginia  22209  and our  telephone  number is (703)  522-1315.  Our
Internet address is http:www.aesc.com.


WHEN WILL YOU RECEIVE DISTRIBUTIONS ON THE PREFERRED SECURITIES?

       The AES  Trusts'  only source of cash to make  payments on the  preferred
securities  are payments on the junior  subordinated  debt trust  securities  it
purchases from AES. If you purchase the preferred  securities,  you are entitled
to receive  cumulative  cash  distributions  at an annual rate which will be set
forth in the applicable  prospectus  supplement.  Distributions  will accumulate
from the date the AES Trusts issue the preferred  securities and will be paid in
arrears.


WHEN WILL PAYMENT OF YOUR DISTRIBUTIONS BE DEFERRED?

       If AES defers  interest  payments on the junior  subordinated  debt trust
securities,  the AES Trust generally will defer  distributions  on the preferred
securities  as described in the  applicable  prospectus  supplement.  During any
deferral period, with certain exceptions, AES will not be permitted to:

       o  pay a  dividend  or make any  distributions  on its  capital  stock or
          redeem, purchase,  acquire or make a liquidation payment on any of its
          capital  stock,  or  make  any  guarantee  payments  relating  to  the
          foregoing; or

       o  make an interest,  principal or premium  payment on, or  repurchase or
          redeem,  any of its debt  securities that rank equal with or junior to
          the junior subordinated debt trust securities.


WHEN CAN THE AES TRUSTS REDEEM THE PREFERRED SECURITIES?

       The AES Trusts must redeem all of the outstanding  trust  securities on a
date that will be specified in the applicable prospectus supplement. Some or all
of the preferred  securities may be redeemed on further dates which will also be
specifed in the applicable prospectus supplement. Also, the preferred securities
may be  redeemed,  in whole or in part,  at any time if certain  changes in tax,
investment company or bank regulatory law occur and certain other conditions are
satisfied. See "Description of the Preferred Securities" on page 22.


WHAT IS AES' GUARANTEE OF THE PREFERRED SECURITIES?

       AES' guarantee of the preferred securities consists of:


                                       3
<PAGE>

       o  its obligations to make payments on the junior subordinated debt trust
          securities;

       o  its obligations under the preferred trust securities guarantee; and

       o  its obligations  under the amended and restated  declarations of trust
          of the AES Trusts,  which sets forth the terms of the AES Trusts.  AES
          has   irrevocably   guaranteed   that  if  a  payment  on  the  junior
          subordinated  debt trust securities is made to the AES Trusts but, for
          any reason, the AES Trusts do not make the corresponding  distribution
          or redemption payment to the holders of the preferred securities, then
          AES will make the  payments  directly to the holders of the  preferred
          securities.  The guarantee does not cover payments when the AES Trusts
          do not  have  sufficient  funds  to  make  payments  on the  preferred
          securities.  AES' obligations  under the guarantee are subordinated as
          described on page 26.


WHEN COULD THE JUNIOR SUBORDINATED TRUST SECURITIES BE DISTRIBUTED TO YOU?

       AES has  the  right  to  dissolve  the AES  Trusts  at any  time.  If AES
terminates the AES Trusts,  the AES Trusts will redeem the preferred  securities
by  distributing  the  junior  subordinated  debt  securities  to holders of the
preferred securities and the common securities on a ratable basis. If the junior
subordinated debt trust securities are distributed, AES will use it best efforts
to list the junior  subordinated  debt trust securities on any exchange on which
the preferred securities are then listed.


WILL THE PREFERRED SECURITIES BE LISTED ON A STOCK EXCHANGE?

       Application will be made to list the preferred securities on the NYSE, or
if AES common  stock is not then listed on the NYSE,  on such other  exchange on
which the AES common  stock is then listed.  If approved  for  listing,  the AES
Trusts expect the preferred  securities  will begin trading within 30 days after
they are first issued.


WILL HOLDERS OF THE PREFERRED SECURITIES HAVE ANY VOTING RIGHTS?

       Generally,  the  holders  of  the  preferred securities will not have any
voting rights. See "Description of the Preferred Securities."


IN WHAT FORM WILL THE PREFERRED SECURITIES BE ISSUED?

       The  preferred  securities  will be  represented  by one or  more  global
securities  that  will be  deposited  with  and  registered  in the  name of The
Depository Trust Company or its nominee.  This means that you will not receive a
certificate  for your  preferred  securities  and that your broker will maintain
your position in the preferred securities.

                                 RISK FACTORS


       Purchasers  of  the  securities   should  read  this  entire   prospectus
carefully.  Ownership of the securities  involves  certain risks.  The following
factors  and the other  information  in this  prospectus  should  be  considered
carefully in evaluating  AES and our 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  $6,800  million  of
outstanding   indebtedness  at  March  31,  1999.  As  a  result,  we  might  be
significantly  limited in our ability to meet our debt service  obligations,  to
finance the  acquisition  and  development  of additional  projects,  to compete
effectively or to operate successfully under adverse economic conditions.  As of
March  31,  1999,  we had a  consolidated  ratio  of total  debt to  total  book
capitalization (including current debt) of approximately 74%.


       We are not  required  to pay  you  under  the  guarantee  and the  junior
subordinated debt trust securities unless we first make other required payments.
Our obligations  under the junior  subordinated  debt trust securities will rank
junior to all of our senior and senior subordinated indebtedness, including, but
not limited to, the amounts outstanding under our current $600 million revolving
credit  facility.  As of March 31, 1999,  we had  approximately  $617 million in
aggregate  principal  amount of senior  debt and  $1,686  million  in  aggregate
principal  amount of senior and  senior  subordinated  debt.  This means that we
cannot make any payments on the junior  subordinated debt trust securities if we
default on a payment of senior indebtedness or senior subordinated  indebtedness
and do not cure the default within the applicable  grace period or if the senior
indebtedness or senior subordinated indebtedness becomes immediately due because
of a default and has not yet been paid in full.  In  addition,  our  obligations
under  the  junior  subordinated  debt  trust  securities  will  be  effectively
subordinated to all existing and future liabilities of our subsidiaries.


       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 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 trust  securities  will be entitled to receive any payment on
the junior subordinated debt trust securities.

       No  payments  in respect of the junior subordinated debt trust securities
may be made if

       o  a default has occurred and is continuing in a payment under the senior
          and senior subordinated debt or

       o  during  certain  periods when an event of default under certain senior
          and senior  subordinated  debt,  respectively,  permits the respective
          lenders thereunder to accelerate the maturity thereof.

       The preferred securities will rank

       o  subordinate   and  junior  in  right  of  payment  to  all  our  other
          liabilities,  including the junior subordinated debt trust securities,
          except those made pari passu by their terms and

       o  senior to all capital  stock now or hereafter  issued by us and to any
          guarantee now or hereafter entered into by us in respect of any of our
          capital stock.

       See  "Description of the Preferred Securities Guarantees -- Status of the
Preferred Securities Guarantees."

       The  junior  subordinated  debt  trust  securities  will  be  effectively
subordinated  to  the  indebtedness  and  other  obligations   (including  trade
payables)  of  our  subsidiaries.  At  March  31,  1999,  the  indebtedness  and
obligations of our subsidiaries  aggregated  approximately  $5,213 million.  Our
ability  to pay  principal  of,  premium,  if any,  and  interest  on the junior
subordinated  debt trust  securities will be dependent upon the receipt of funds
from our subsidiaries by way of dividends,  fees, interest,  loans or otherwise.
There  are no  terms in the  junior  subordinated  debt  trust  securities,  the
preferred securities or the preferred securities guarantee that limit our or our
subsidiaries' ability to incur additional indebtedness. Most of our subsidiaries
with


                                       5
<PAGE>

interests in power generation  facilities  currently have in place  arrangements
that  restrict  their ability to make  distributions  to us by way of dividends,
fees, interest,  loans or otherwise.  Our subsidiaries are separate and distinct
legal  entities and have no  obligation,  contingent  or  otherwise,  to pay any
amounts due pursuant to the junior  subordinated  debt trust  securities  or the
preferred  securities  or to make  any  funds  available  therefor,  whether  by
dividends, loans or other payments, and do not guarantee the payment of interest
on or  principal  of  the  junior  subordinated  debt  trust  securities  or the
preferred  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 junior subordinated debt trust securities
and preferred  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 are not required to pay you under the guarantee if the  applicable AES
Trusts do not have cash  available.  The ability of the  applicable AES Trust to
make payments on the preferred securities is solely dependent upon us making the
related payments on the junior  subordinated  debt trust securities when due. If
we default on our obligations to make payments on the junior  subordinated  debt
trust  securities,  the applicable AES Trust will not have  sufficient  funds to
make payments on the preferred securities. In those circumstances,  you will not
be able to rely upon the guarantee for payment of these amounts.


       Our ability to make distributions.  The ability of the AES Trusts to make
distributions and other payments on the preferred securities is solely dependent
upon us making interest and other payments on the junior subordinated debt trust
securities  deposited  as trust assets as and when  required.  If we were not to
make  distributions  or other  payments  on the junior  subordinated  debt trust
securities  for any reason,  including  as a result of our election to defer the
payment  of  interest  on the  junior  subordinated  debt  trust  securities  by
extending the interest period on the junior  subordinated debt trust securities,
the AES Trusts will not make  payments on the preferred  securities.  In such an
event,  holders  of the  preferred  securities  would not be able to rely on the
preferred  securities  guarantee since  distributions  and other payments on the
preferred  securities  are subject to this  guarantee  only if and to the extent
that we have made a payment  to the  Property  Trustee  (as  defined  herein) of
interest or principal on the junior subordinated debt trust securities deposited
in the trust as trust assets.  Instead,  holders of preferred  securities  would
rely on the  enforcement  by the  Property  Trustee of its rights as  registered
holder of the junior  subordinated debt trust securities  against us pursuant to
the terms of the Indenture (as defined herein).  However, if the Trust's failure
to make  distributions  on the  preferred  securities  is a  consequence  of the
exercise by us of our right to extend the interest payment period for the junior
subordinated debt trust  securities,  the Property Trustee will have no right to
enforce the payment of distributions on the preferred  securities until an Event
of Default (as defined  herein) under the  Declaration (as defined herein) shall
have occurred.


       The Declaration  provides that we shall pay for all debts and obligations
(other than with respect to the Trust  Securities) and all costs and expenses of
the AES Trusts,  including  any taxes and all costs and  expenses  with  respect
thereto,  to which the AES Trusts may become  subject,  except for United States
withholding  taxes.  No  assurance  can be given  that we will  have  sufficient
resources  to enable it to pay these debts,  obligations,  costs and expenses on
behalf of the AES Trusts.


       Option to extend  interest  payment period;  tax impact of extension.  So
long  as we are  not in  default  in  the  payment  of  interest  on the  junior
subordinated  debt trust  securities,  we have the right under the  indenture to
defer payments of interest on the junior  subordinated  debt trust securities by
extending  the  interest  payment  period  from  time  to  time  on  the  junior
subordinated  debt trust  securities  for an extension  period not  exceeding 20
consecutive quarterly interest periods (an "Extension Period"),  during which no
interest shall be due and payable. In this event, quarterly distributions on the
preferred  securities  would not be made by the  applicable AES Trust during any
Extension Period. If we exercise the right to extend an


                                       6
<PAGE>

interest  payment period,  we may not during the Extension Period declare or pay
dividends on, or redeem, purchase, acquire or make a distribution or liquidation
payment with respect to, any of its common  stock or preferred  stock;  provided
that:


       o  we will be  permitted  to pay accrued  dividends  upon the exchange or
          redemption  of  any  series  of  preferred  stock  of  AES  as  may be
          outstanding  from time to time, in  accordance  with the terms of that
          stock and


       o  the foregoing will not apply to stock dividends paid by us.


       Under our certificate of incorporation,  we are authorized to issue up to
50,000,000  shares of preferred  stock.  As of June 29,  1999,  no shares of our
preferred stock were  outstanding.  We may from time to time offer shares of our
preferred stock to the public.


       Prior to the termination of any Extension  Period,  we may further extend
that Extension  Period;  provided that such Extension  Period  together with all
such  previous  and further  extensions  thereof  may not exceed 20  consecutive
quarterly interest periods. Upon the termination of any Extension Period and the
payment of all amounts then due, we may commence a new Extension Period, subject
to the above requirements.  We may also prepay at any time all or any portion of
the interest accrued during an Extension  Period.  Consequently,  there could be
multiple  Extension Periods of varying lengths throughout the term of the junior
subordinated debt trust securities,  not to exceed 20 consecutive quarters or to
cause any extension  beyond the maturity of the junior  subordinated  debt trust
securities.  See any  accompanying  prospectus  supplement  relating  to  junior
subordinated debt trust securities.


       Because we have the right to extend the  interest  payment  period for an
Extension Period of up to 20 consecutive  quarterly  interest periods on various
occasions,  the junior  subordinated  debt trust  securities  will be treated as
issued with  "original  issue  discount"  for United States  federal  income tax
purposes.  As a result,  holders of  preferred  securities  will be  required to
include  their pro rata share of original  issue  discount in gross income as it
accrues for United States  federal income tax purposes in advance of the receipt
of cash.  Generally,  all of a  securityholder's  taxable  interest  income with
respect to the junior  subordinated  debt trust securities will be accounted for
as "original  issue discount" and actual  distributions  of stated interest will
not be separately  reported as taxable income.  See any accompanying  prospectus
supplement relating to junior subordinated debt trust securities.

       Deferral of distributions would have adverse tax consequences for you and
may  adversely  affect  the  trading  price  of  the  preferred  securities.  If
distributions on the preferred securities are deferred,  you will be required to
recognize  interest  income for United  States  federal  income tax  purposes in
respect of your ratable  share of the interest on the junior  subordinated  debt
trust  securities  held by the  applicable AES Trust before you receive any cash
distributions  relating to this interest. In addition, you will not receive this
cash if you sold the preferred  securities before the end of any deferral period
or before the record date relating to  distributions  which are paid. We have no
current intention of deferring interest payments on the junior subordinated debt
trust securities. However, if we exercise our right in the future, the preferred
securities may trade at a price that does not fully reflect the value of accrued
but unpaid interest on the junior  subordinated  debt trust  securities.  If you
sell the preferred  securities during an interest  deferral period,  you may not
receive the same return on  investment as someone else who continues to hold the
preferred securities.  In addition, the existence of our right to defer payments
of interest on the junior  subordinated  debt trust securities may mean that the
market  price  for  the  preferred  securities,  which  represent  an  undivided
beneficial  interest in the junior  subordinated debt trust  securities,  may be
more volatile than other securities that do not have these rights.

       You should not rely on the  distributions  from the preferred  securities
through  their  maturity  date -- they may be  redeemed  at any time if  certain
changes in tax, or  regulatory  law occur.  If certain  changes,  which are more
fully described  below,  in tax law occur and are continuing,  and certain other
conditions  which are more fully  described  below are satisfied,  the preferred
securities  could be redeemed by the AES Trusts within 90 days of the event at a
redemption  price set forth in the  applicable  prospectus  supplement  plus any
accrued and unpaid distributions. See "Description of the Preferred Securities".


                                       7
<PAGE>

       You should not rely on the  distributions  from the preferred  securities
through  their  maturity  date -- they may be redeemed at the option of AES. The
preferred  securities may be redeemed,  in whole,  at any time, or in part, from
time to  time,  on or after  the date  specified  in the  applicable  prospectus
supplement  at a  redemption  price  set  forth  in  the  applicable  prospectus
supplement plus any accrued and unpaid distributions to the redemption date. You
should  assume that this  redemption  option will be exercised if we are able to
refinance at a lower  interest rate or it is otherwise in our interest to redeem
the junior  subordinated debt securities.  If the junior subordinated debt trust
securities are redeemed, the AES Trusts must redeem the preferred securities and
the  common  securities  having an  aggregate  liquidation  amount  equal to the
aggregate  principal amount of junior  subordinated  debt trust securities to be
redeemed.  See "Description of the Preferred Securities" and "Description of the
Junior Subordinated Debt Trust Securities" on pages 23 and 27, respectively.


       There can be no  assurance  as to the  market  prices  for the  preferred
securities or the junior subordinated debt trust securities;  therefore, you may
suffer a loss.  The AES Trusts and AES cannot give you any  assurance  as to the
market prices for the preferred securities or the junior subordinated debt trust
securities  that  may be  distributed  in  exchange  for  preferred  securities.
Accordingly,  the preferred  securities  that an investor may purchase,  whether
pursuant to the offer made by this prospectus or in the secondary market, or the
junior subordinated debt trust securities that a holder of preferred  securities
may receive in exchange for preferred securities, may trade at a discount to the
price that the investor paid to purchase the preferred  securities.  As a result
of the right to defer payments on the preferred securities,  the market price of
the  preferred  securities  may be more volatile than the market prices of other
securities to which such optional deferrals do not apply.


       There could be an adverse tax  consequence to you if we terminate the AES
Trusts and  distribute  junior  subordinated  debt trust  securities to holders,
resulting in possible tax and liquidity  consequences  to you. We have the right
to  terminate  the AES Trusts at any time,  so long as it obtains  any  required
regulatory  approval.  If we decide to exercise our right to  terminate  the AES
Trusts,  they will redeem the  preferred  securities  and common  securities  by
distributing  the junior  subordinated  debt trust  securities to holders of the
preferred  securities and common  securities on a ratable  basis.  Under current
United States federal income tax law, a distribution of junior subordinated debt
trust  securities  to you on the  dissolution  of an AES Trust  should  not be a
taxable event to you.  However,  if the AES Trusts are  characterized for United
States federal income tax purposes as an association taxable as a corporation at
the time it is  dissolved or if there is a change in law,  the  distribution  of
junior subordinated debt trust securities to you may be a taxable event to you.


       There may be no trading  market for the  junior  subordinated  debt trust
securities if the AES Trusts  distribute  them to you.  Although we will use our
best  efforts  to list the junior  subordinated  debt  trust  securities  on the
exchange  on  which  the  preferred  securities  are  then  listed,  if they are
distributed,  we cannot  assure  you that the  junior  subordinated  debt  trust
securities  will be approved for listing or that a trading market will exist for
those securities.

       Since you have limited  voting  rights,  you cannot prevent the AES Trust
trustees  from  taking  actions you may not agree  with.  You will have  limited
voting rights. In particular, except for the limited exceptions described below,
only AES can elect or remove any of the AES Trusts' trustees.

       Special Event Redemption or Distribution.  Upon the occurrence and during
the  continuation  of a Tax Event or  Investment  Company Event (each as defined
herein), which may occur at any time, the applicable AES Trust shall, unless the
junior   subordinated   debt  trust  securities  are  redeemed  in  the  limited
circumstances  described  below,  be  dissolved  with  the  result  that  junior
subordinated debt trust securities having an aggregate principal amount equal to
the  aggregate  stated  liquidation  amount of, and  bearing  accrued and unpaid
distributions  on,  the  preferred  securities  and common  securities  would be
distributed  on a Pro Rata  Basis (as  defined  herein  under "The AES Trusts --
Distributions") to the holders of the preferred securities and common securities
in  liquidation  of  that  trust.  In  the  case  of a  Tax  Event,  in  certain
circumstances,  we  shall  have  the  right to  redeem  at any  time the  junior
subordinated debt trust securities in whole or in part, in which event the


                                       8
<PAGE>

applicable AES Trust will redeem preferred securities and common securities on a
Pro  Rata  Basis  to the same  extent  as the  junior  subordinated  debt  trust
securities  are redeemed.  There can be no assurance as to the market prices for
preferred  securities or the junior subordinated debt trust securities which may
be  distributed  in exchange  for  preferred  securities  if a  dissolution  and
liquidation  of the  applicable  AES  Trust  were  to  occur.  Accordingly,  the
preferred  securities that an investor may purchase,  or the junior subordinated
debt  trust  securities  that  the  investor  may  receive  on  dissolution  and
liquidation of the  applicable  AES Trust,  may trade at a discount to the price
that the investor  paid to purchase the  preferred  securities  offered  hereby.
Because  holders of preferred  securities may receive junior  subordinated  debt
trust  securities  upon the  occurrence of a Special Event (as defined  herein),
prospective  purchasers  of preferred  securities  are also making an investment
decision with regard to the junior subordinated debt trust securities and should
carefully  review all the  information  regarding the junior  subordinated  debt
trust securities contained in any accompanying prospectus supplement relating to
junior subordinated debt trust securities.

       There can be no assurance that future federal legislative  proposals will
not prevent us from  deducting  interest on the junior  subordinated  debt trust
securities.  This  would  constitute  a  Tax  Event  and  could  result  in  the
distribution of any junior  subordinated debt trust securities to holders of the
preferred  securities  or, in certain  circumstances,  the  redemption  of these
securities by us and the distribution of the resulting cash in redemption of the
preferred  securities.  See any accompanying  prospectus  supplement relating to
junior subordinated debt trust securities.

       "Tax Event"  means that the Regular  Trustees (as defined  herein)  shall
have  obtained an opinion of a  nationally  recognized  independent  tax counsel
experienced in such matters (a "Dissolution  Tax Opinion") to the effect that on
or after the date of any accompanying  prospectus  supplement relating to junior
subordinated debt trust securities as a result of

         o   any  amendment  to,  or  change  in,  the laws (or any  regulations
             thereunder)  of the United States or any political  subdivision  or
             taxing authority thereof or therein,

         o   any amendment to, or change in, an interpretation or application of
             any  such  laws or  regulations  by any  legislative  body,  court,
             governmental   agency  or  regulatory   authority   (including  the
             enactment of any  legislation  and the  publication of any judicial
             decision or regulatory determination),

         o   any  interpretation  or pronouncement  that provides for a position
             with  respect to such laws or  regulations  that  differs  from the
             theretofore generally accepted position or

         o   any  action  taken  by  any   governmental   agency  or  regulatory
             authority,  which  amendment  or  change is  enacted,  promulgated,
             issued or effective or which  interpretation  or  pronouncement  is
             issued or announced  or which  action is taken,  in each case on or
             after the date of such prospectus  supplement,  where there is more
             than an insubstantial risk that

         o   the  applicable AES Trust is, or will be within 90 days of the date
             thereof,  subject to United States  federal income tax with respect
             to income accrued or received on the junior subordinated debt trust
             securities,  the applicable AES Trust is, or will be within 90 days
             of the date  thereof,  subject to more than a de minimis  amount of
             other taxes, duties or other governmental charges or

         o   interest  payable by us to the  applicable  AES Trust on the junior
             subordinated debt trust securities is not, or within 90 days of the
             date  thereof  will  not be,  deductible  by us for  United  States
             federal income tax purposes.

       "Investment  Company  Event" means that the Regular  Trustees  shall have
received an opinion of nationally recognized  independent counsel experienced in
practice under the Investment  Company Act of 1940, as amended (the "1940 Act"),
that as a result of the  occurrence of a change in law or regulation or a change
in  interpretation  or application of law or regulation by any legislative body,
court,


                                       9
<PAGE>

governmental agency or regulatory  authority (a "Change in 1940 Act Law"), there
is more than an insubstantial risk that an AES Trust is or will be considered an
"investment  company"  which is  required to be  registered  under the 1940 Act,
which  Change  in 1940 Act Law  becomes  effective  on or after  the date of any
accompanying  prospectus  supplement  relating to junior subordinated debt trust
securities.

       "Special Event" means a Tax Event or an Investment Company Event.

       The preferred  securities  constitute a new issue of  securities  with no
established  trading market. The preferred  securities may trade at a price that
does not fully reflect the value of accrued but unpaid  interest with respect to
the underlying junior subordinated debt trust securities.  A holder who disposes
of his preferred  securities  between record dates for payments of distributions
thereon  will be required to include  accrued but unpaid  interest on the junior
subordinated debt trust securities  through the date of disposition in income as
ordinary  income,  and to add such amount to his  adjusted  tax basis in his pro
rata share of the underlying  junior  subordinated  debt trust securities deemed
disposed  of.  Accordingly,  such a holder will  recognize a capital loss to the
extent the selling  price (which may not fully  reflect the value of accrued but
unpaid interest) is less than the holders adjusted tax basis (which will include
accrued but unpaid  interest).  Subject to certain limited  exceptions,  capital
losses cannot be applied to offset  ordinary  income for United  States  federal
income tax purposes.  See any  accompanying  prospectus  supplement  relating to
junior subordinated debt trust securities.

       Potential market  volatility during Extension Period. As described above,
we  have  the  right  to  extend  an  interest  payment  period  on  the  junior
subordinated  debt trust securities from time to time for a period not exceeding
20 consecutive quarterly interest periods. If we determine to extend an interest
payment  period,  or if we  thereafter  extend  an  Extension  Period  or prepay
interest accrued during an Extension Period as described above, the market price
of the preferred securities is likely to be affected.  In addition,  as a result
of these rights,  the market price of the preferred  securities (which represent
an undivided interest in junior  subordinated debt trust securities) may be more
volatile than other  securities on which original issue discount accrues that do
not have such rights. A holder that disposes of its preferred  securities during
an  Extension  Period,  therefore,  may  not  receive  the  same  return  on its
investment as a holder that continues to hold its preferred securities.  See any
accompanying  prospectus  supplement  relating to junior subordinated debt trust
securities.

       We do a  significant  amount of our  business  outside the United  States
which presents  significant  risks.  Our  involvement in the  development of new
projects and the acquisition of existing plants in locations  outside the United
States  is  increasing  and  most of our  current  development  and  acquisition
activities  are for  projects  and plants  outside  the United  States.  We have
ownership interests in 104 power plants in operation or under  construction,  87
of these are outside of 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,  currency  inconvertibility,  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  may  also  require  us  to  make  higher  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 projects. In addition, the laws and regulations of certain countries may
limit our ability to hold a majority  interest in some of the  projects  that we
may develop or acquire.  International projects we own may, in certain cases, be
expropriated by applicable


                                       10
<PAGE>

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.


       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  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 trust 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 assurance
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  future
acquisitions  and projects.  Each of our projects  under  development  and those
independent  power  facilities  we may seek to acquire may  require  substantial
capital  investment.  Continued  access  to  capital  with  acceptable  terms is
necessary to assure the


                                       11
<PAGE>

success of future projects and acquisitions.  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.

       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 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
subordinated notes, convertible debentures 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,  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.


       Our  performance  is dependent to a large degree on certain of our larger
projects and their utility  customers.  The nature of most of our power projects
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 one utility customer to
fulfill its contractual  obligations could have a substantial negative impact on
our primary  source of  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 its plants in different geographic areas in order
to mitigate the effects of regional economic downturns.


       We are subject to significant  government  regulation.  Our  cogeneration
operations  in the United  States are subject to the  provisions of various laws
and regulations,  including the Public Utility Regulatory  Policies Act of 1978,
as amended  ("PURPA")  and the Public  Utility  Holding  Company Act, as amended
("PUHCA").  PURPA provides to qualifying  facilities  ("QFs") certain exemptions
from substantial federal and state legislation,  including  regulation as public
utilities.   PUHCA  regulates   public  utility  holding   companies  and  their
subsidiaries.  We are not and will not be  subject  to  regulation  as a holding
company  under PUHCA as long as the  domestic  power plants we own are QFs under
PURPA.  QF status is  conditioned  on  meeting  certain  criteria,  and would be
jeopardized, for example, by the loss of a steam customer. 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


                                       12
<PAGE>

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  Federal  Energy  Regulatory  Commission  ("FERC") to obtain
status  as an Exempt  Wholesale  Generator  ("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.


       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 both  independent  power  producers  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
integration. 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 of a PUHCA repeal,  competition for independent  power
generators from vertically integrated utilities would likely increase. Repeal of
PURPA  andor  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.

       Pending electric utility industry  restructuring  proposals could have an
adverse effect on us. 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. 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 for United States electricity sellers.
Falling  electricity  prices and  uncertainty as to the future  structure of the
industry is inhibiting  United  States  utilities  from entering into  long-term
power purchase contracts.  The effect on us of any such restructuring  cannot be
predicted,  although any such restructuring 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
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.


                                       13

       Our  business  is subject to  stringent  environmental  regulations.  Our
activities are subject to stringent environmental  regulation by federal, state,
local and foreign governmental authorities. For example, the United States Clean
Air Act Amendments of 1990 impose more stringent standards than those previously
in effect,  and  require  states to impose  permit  fees on  certain  emissions.
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.

       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 2, 1999, our two founders,  Roger W. Sant and Dennis W.
Bakke, and their immediate  families together owned  beneficially  approximately
21.7% 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 2,
1999, all of our officers and directors and their  immediate  families  together
owned beneficially  approximately  29.1% 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 the junior  subordinated  debentures 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 junior subordinated debentures,

         o   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

         o   received   less   than   reasonably   equivalent   value   or  fair
             consideration for issuing junior subordinated debentures and we

         o   were insolvent,


         o   were rendered insolvent  by  reason  of  the issuance of the junior
             subordinated debentures,


         o   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


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


                                       14
<PAGE>

             each case, a court of competent  jurisdiction  could void, in whole
             or in part, the junior subordinated debentures.

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

       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 claims, there will be sufficient assets to satisfy
the claims of the holders of the junior subordinated debentures.

       Management believes that, for purposes of all such insolvency, bankruptcy
and fraudulent transfer or conveyance laws, the junior  subordinated  debentures
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
junior subordinated debentures 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 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 the securities that may be offered pursuant to this prospectus. There
can be no assurance that an active  trading  market for any of these  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.  Historically,  the
market for non-investment grade debt has demonstrated  substantial volatility in
prices  of  securities  similar  to the  securities  offered  pursuant  to  this
prospectus.  There  can  be no  assurance  that  the  future  market  for  these
securities will not be subject to similar volatility.  Accordingly, no assurance
can be given as to the liquidity of the securities offered by this prospectus.

                       RATIO OF EARNINGS TO FIXED CHARGES


       Our ratio of earnings to fixed charges is as follows:

</TABLE>

       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 fixed charges, less capitalized interest, less excess of
earnings  over  dividends  of  less-than-fifty-percent-owned   companies.  Fixed
charges   consist  of  interest   (including   capitalized   interest)   on  all
indebtedness,  amortization  of debt  discount  and expense and that  portion of
rental expense which we believe to be representative of an interest factor.

       During the period from January 1, 1994 until March 31, 1999, no shares of
preferred stock were issued or  outstanding,  and during that period the Company
did not pay any preferred stock dividends.

                                  THE COMPANY

       We help to meet the world's needs by supplying  electricity  to customers
in many countries in a socially responsible way.

       We have been  successful  in growing our business and serving  additional
customers  by   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. In such privatizations, sellers generally
seek to complete  competitive  solicitations 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.  Since 1994, our total  generating  capacity in
megawatts  or MW has grown  from  2,479 MW to  24,076  MW at March 31,  1999 (an
increase of 871%), with the total number of plants in operation  increasing from
9 to 89.  Additionally,  our total revenues have increased at a compound  annual
growth rate of 46% from $533  million in 1994 to $2,398  million in 1998,  while
net  income has  increased  at a compound  annual  growth  rate of 33% from $100
million to $311 million over the same period.

       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 usually made under long-term
contracts from power plants owned by our subsidiaries  and affiliates,  although
we do, in certain  circumstances,  make sales into regional  electricity markets
without  contracts.  Our ownership  portfolio of power  facilities  includes new
plants  constructed for such purposes,  so-called  greenfield plants, 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


                                       17
<PAGE>

(entirely or in part) a diverse  portfolio of electric  power plants  (including
those within integrated  distribution companies) with a total capacity of 24,076
MW. Of that total,  29% are fueled by coal or petroleum  coke, 24% are fueled by
natural gas,  33% are  hydroelectric  facilities,  6% are fueled by oil, and the
remaining 8% are capable of using multiple fossil fuels.

                                THE AES TRUSTS

       Each of AES  Trust  III,  AES  Trust  IV and AES  Trust V is a  statutory
business  trust formed,  in the case of AES Trust III, on November 13, 1996, and
in the case of AES Trust IV and AES Trust V, on November  5, 1997,  in each case
under the Delaware  Business Trust Act (the "Business  Trust Act") pursuant to a
separate declaration of trust among the Trustees (as defined herein) of that AES
Trust and us and the  filing of a  certificate  of trust with the  Secretary  of
State of the State of Delaware. This declaration will be amended and restated in
its entirety (as so amended and restated,  the  "Declaration")  substantially in
the  form  filed as an  exhibit  to the  Registration  Statement  of which  this
prospectus  forms a part,  as of the date the  Preferred  Securities  of the AES
Trust are initially  issued.  Each Declaration will be qualified under the Trust
Indenture Act of 1939, (the "Trust Indenture Act").

       This description summarizes the material terms of the Declarations and is
qualified in its entirety by  reference  to the form of  Declaration,  which has
been filed as an exhibit to the Registration  Statement of which this prospectus
is a part, and the Trust Indenture Act.

TRUST SECURITIES

       Upon  issuance of any preferred  securities by an AES Trust,  the holders
thereof will own all of the issued and outstanding  preferred securities of that
AES Trust. We will acquire securities  representing common undivided  beneficial
interests in the assets of each AES Trust (the "common securities" and, together
with the preferred securities,  the "Trust Securities") in an amount equal to at
least 3% of the  total  capital  of that AES Trust  and will  own,  directly  or
indirectly,  all of the issued and  outstanding  common  securities  of each AES
Trust. The preferred  securities and the common  securities will rank pari passu
with each other and will have equivalent terms; provided that

       o  if a Declaration  Event of Default (as defined herein under  "--Events
          of  Default")  under the  Declaration  of an AES Trust  occurs  and is
          continuing, the holders of preferred securities of that AES Trust will
          have a priority  over  holders of the  common  securities  of that AES
          Trust  with  respect to  payments  in  respect  of  distributions  and
          payments upon liquidation, redemption and maturity and

       o  holders of common  securities have the exclusive right (subject to the
          terms of the  Declaration) to appoint,  remove or replace the trustees
          and to increase or decrease the number of trustees.

       Each AES Trust exists for the purpose of

       o  issuing its preferred securities,

       o  issuing its common securities to AES,

       o  investing the gross proceeds from the sale of the Trust  Securities in
          junior subordinated debt trust securities of AES and

       o  engaging in only such other activities as are necessary, convenient or
          incidental  thereto.  The  rights  of the  holders  of  the  preferred
          securities,  including  economic  rights,  rights to  information  and
          voting  rights,  are set  forth  in the  applicable  Declaration,  the
          Business Trust Act and the Trust Indenture Act.


POWERS AND DUTIES OF TRUSTEES

       The number of trustees of each AES Trust shall  initially be five.  Three
of these Trustees (the  "Regulator  Trustees") are individuals who are employees
or  officers  of AES.  The fourth  trustee  will be The First  National  Bank of
Chicago,  which is  unaffiliated  with AES and which will serve as the  property
trustee (the "Property  Trustee") and act as the indenture  trustee for purposes
of the Trust  Indenture  Act. The fifth trustee is First  Chicago  Delaware Inc.
that has its principal place of business in the State of Delaware (the "Delaware
Trustee"). Pursuant to each Declaration,  legal title to the junior subordinated
debt trust securities purchased by an AES Trust will be held by the


                                       18
<PAGE>

Property  Trustee for the benefit of the holders of the Trust Securities of such
AES Trust,  and the Property Trustee will have the power to exercise all rights,
powers and privileges under the Indenture (as defined under  "Description of the
Junior   Subordinated  Debt  Trust  Securities")  with  respect  to  the  junior
subordinated  debt trust  securities.  In addition,  the  Property  Trustee will
maintain  exclusive  control of a segregated  non-interest  bearing bank account
(the  "Property  Account")  to  hold  all  payments  in  respect  of the  junior
subordinated debt trust securities  purchased by an AES Trust for the benefit of
the  holders of Trust  Securities.  The  Property  Trustee  will  promptly  make
distributions  to the  holders  of the Trust  Securities  out of funds  from the
Property Account. The preferred  securities  guarantees are separately qualified
under the Trust  Indenture  Act and will be held by The First  National  Bank of
Chicago,  acting in its capacity as indenture trustee with respect thereto,  for
the benefit of the holders of the applicable  preferred  securities.  As used in
this prospectus and any accompanying  prospectus supplement,  the term "Property
Trustee"  with  respect  to an AES Trust  refers to The First  National  Bank of
Chicago  acting  either  in  its  capacity  as  a  trustee  under  the  relevant
Declaration and the holder of legal title to the junior  subordinated debt trust
securities  purchased  by that trust or in its  capacity  as  indenture  trustee
under, and the holder of, the applicable preferred securities guarantee,  as the
context may require.  AES, as the direct or indirect  owner of all of the common
securities  of each AES Trust,  will have the  exclusive  right  (subject to the
terms of the related Declaration) to appoint,  remove or replace Trustees and to
increase  or  decrease  the  number of  trustees,  provided  that the  number of
trustees  shall be,  except under certain  circumstances,  at least five and the
majority of trustees shall be Regular Trustees. The terms of the AES Trusts will
be set forth in the prospectus supplement, but may terminate earlier as provided
in such Declaration.

       The duties  and  obligations  of the  Trustees  of an AES Trust  shall be
governed by the  Declaration  of that AES Trust,  the Business Trust Act and the
Trust  Indenture Act. Under its  Declaration,  each AES Trust shall not, and the
Trustees shall cause such AES Trust not to, engage in any activity other than in
connection  with the  purposes  of that AES Trust or other than as  required  or
authorized by the related Declaration.  In particular,  each AES Trust shall not
and the Trustees shall cause each AES Trust not to

       o  invest any proceeds received by that AES Trust from holding the junior
          subordinated  debt trust  securities  purchased  by that AES Trust but
          shall promptly  distribute from the Property Account all such proceeds
          to holders of Trust  Securities  pursuant  to the terms of the related
          Declaration and of the Trust Securities;

       o  acquire any  assets  other  than  as expressly provided in the related
          Declaration;

       o  possess Trust property for other than a Trust purpose;

       o  make  any  loans,   other  than  loans   represented   by  the  junior
          subordinated debt trust securities;

       o  possess any power or otherwise act in such a way as to vary the assets
          of such AES  Trust or the  terms of its  Trust  Securities  in any way
          whatsoever;

       o  issue any securities or other evidences of beneficial ownership of, or
          beneficial   interests  in,  such  AES  Trust  other  than  its  Trust
          Securities;

       o  incur any indebtedness for borrowed money or

       o  or

              --   direct the time,  method and place of exercising any trust or
                   power conferred upon the Indenture  Trustee (as defined under
                   "Description   of  the   Junior   Subordinated   Debt   Trust
                   Securities")  with  respect to the junior  subordinated  debt
                   trust securities  deposited in that AES Trust as trust assets
                   or upon the  Property  Trustee of that AES Trust with respect
                   to its preferred securities,

              --   waive any past default that is waivable under  the  Indenture
                   or the Declaration,

              --   exercise any right to rescind or annul any  declaration  that
                   the  principal of all of the junior  subordinated  debt trust
                   securities  deposited in that AES Trust as trust assets shall
                   be due and payable or

              --   consent to any amendment,  modification or termination of the
                   Indenture or such junior  subordinated debt trust securities,
                   in each case where such consent shall be required,  unless in
                   the case described in this bullet point the Property  Trustee
                   shall have  received  an  unqualified  opinion of  nationally
                   recognized  independent  tax counsel  recognized as expert in
                   such  matters to the effect  that such  action will not cause
                   such AES Trust to be  classified  for United  States  federal
                   income  tax   purposes  as  an   association   taxable  as  a
                   corporation  or a  partnership  and that such AES Trust  will
                   continue  to be  classified  as a grantor  trust  for  United
                   States federal income tax purposes.


BOOKS AND RECORDS

       The  books  and  records  of each AES  Trust  will be  maintained  at the
principal  office of such AES Trust and will be open for  inspection by a holder
of preferred  securities of that AES Trust or his representative for any purpose
reasonably  related to his  interest in such AES Trust  during  normal  business
hours.  Each holder of  preferred  securities  will be furnished  annually  with
unaudited financial  statements of the applicable AES Trust as soon as available
after the end of such AES Trust's fiscal year.

VOTING

       Holders of preferred securities will have limited voting rights, but will
not be able to appoint, remove or replace, or to increase or decrease the number
of, Trustees, which rights are vested exclusively in the common securities.

THE PROPERTY TRUSTEE

       The  Property  Trustee,  for the  benefit  of the  holders  of the  Trust
Securities of an AES Trust, is authorized under each Declaration to exercise all
rights under the Indenture  with respect to the junior  subordinated  debt trust
securities deposited in that AES Trust as trust assets,  including its rights as
the holder of those junior  subordinated  debt trust  securities  to enforce our
obligations  under  the  junior  subordinated  debt  trust  securities  upon the
occurrence  of  an  Indenture   Event  of  Default  (as  defined   herein  under
"Description of the Junior Subordinated Debt Trust Securities--Indenture  Events
of  Default").  The Property  Trustee  shall also be  authorized  to enforce the
rights of holders of  preferred  securities  of an AES Trust  under the  related
preferred securities guarantee. If any AES Trust's failure to make distributions
on the preferred  securities of an AES Trust is a consequence of our exercise of
any right  under the terms of the  junior  subordinated  debt  trust  securities
deposited  in that AES  Trust as trust  assets to extend  the  interest  payment
period for those junior subordinated debt trust securities, the Property Trustee
will have no right to enforce the payment of  distributions  on those  preferred
securities until a Declaration Event of Default shall have occurred.

       Holders of at least a majority  in  liquidation  amount of the  preferred
securities  held by an AES Trust  will have the  right to  direct  the  Property
Trustee for that AES Trust with respect to certain matters under the Declaration
for that AES  Trust  and the  related  preferred  securities  guarantee.  If the
Property  Trustee  fails to enforce its rights  under the  Indenture or fails to
enforce  the  preferred  securities  guarantee,   to  the  extent  permitted  by
applicable  law, any holder of preferred  securities  may,  after a period of 30
days has elapsed from such Holder's  written request to the Property  Trustee to
enforce such  rights,  institute a legal  proceeding  against us to enforce such
rights or the preferred securities  guarantee,  as the case may be. In addition,
the  holders  of at  least  25%  in  aggregate  liquidation  preference  of  the
outstanding  preferred  securities  would have the right to  directly  institute
proceedings  for  enforcement  of payments to such holders of  principal  of, or
premium,  if any, or interest on the junior  subordinated  debt trust securities
having a principal amount equal to the aggregate  liquidation  preference of the
preferred  securities of such holders (a "Direct  Action").  In connection  with
such  Direct  Action,  we will be  subrogated  to the  rights of that  holder of
preferred  securities under the Declaration to the extent of any payment made by
us to that holder of preferred securities in the Direct Action.  Notwithstanding
the  foregoing,  if an Event of Default  under the  applicable  Declaration  has
occurred and is continuing and such event is  attributable  to the failure of us
to pay  interest or principal on the  applicable  series of junior  subordinated
debt trust  securities  on the date such  interest  or  principal  is  otherwise
payable (or


                                       20
<PAGE>

in the case of redemption,  on the redemption  date), then a holder of preferred
securities of that AES Trust may directly institute a proceeding for enforcement
of payment to that holder of the  principal  of or  interest  on the  applicable
series of junior  subordinated  debt trust securities  having a principal amount
equal to the aggregate  liquidation  amount of the preferred  securities of that
holder (a "Holder Direct  Action") on or after the respective due date specified
in the  applicable  series of junior  subordinated  debt  trust  securities.  In
connection  with that Holder Direct Action,  we will be subrogated to the rights
of that holder of preferred  securities under the applicable  Declaration to the
extent of any payment made by us to that holder of preferred  securities  in the
Holder Direct Action.


DISTRIBUTIONS

       Pursuant to each Declaration,  distributions on the preferred  securities
of an AES  Trust  must be paid on the  dates  payable  to the  extent  that  the
Property Trustee for that AES Trust has cash on hand in the applicable  Property
Account to permit the  payment.  The funds  available  for  distribution  to the
holders of the preferred  securities of an AES Trust will be limited to payments
received  by the  Property  Trustee in respect of the junior  subordinated  debt
trust  securities that are deposited in the AES Trust as trust assets.  If we do
not make  interest  payments on the junior  subordinated  debt trust  securities
deposited in an AES Trust as trust  assets,  the Property  Trustee will not make
distributions  on  the  preferred  securities  of  that  AES  Trust.  Under  the
Declaration,  if and to the  extent  we make  interest  payments  on the  junior
subordinated  debt trust  securities  deposited in an AES Trust as trust assets,
the Property Trustee is obligated to make  distributions on the Trust Securities
of that AES  Trust on a Pro Rata  Basis  (as  defined  below).  The  payment  of
distributions  on the preferred  securities of an AES Trust is guaranteed by AES
on a subordinated basis as and to the extent set forth under "Description of the
Preferred Securities Guarantee." A preferred securities guarantee is a guarantee
from  the time of  issuance  of the  applicable  preferred  securities,  but the
preferred  securities  guarantee covers  distributions and other payments on the
applicable  preferred  securities  only if and to the extent that we have made a
payment  to the  Property  Trustee  of  interest  or  principal  on  the  junior
subordinated  debt trust securities  deposited in the AES Trust as trust assets.
As used in this  prospectus,  the term "Pro Rata  Basis"  shall mean pro rata to
each  holder of Trust  Securities  of an AES Trust  according  to the  aggregate
liquidation  amount  of the  Trust  Securities  of that  AES  Trust  held by the
relevant  holder in relation to the  aggregate  liquidation  amount of all Trust
Securities of that AES Trust  outstanding  unless,  in relation to a payment,  a
Declaration  Event  of  Default  under  the  Declaration  has  occurred  and  is
continuing,  in which case any funds available to make the payment shall be paid
first to each  holder  of the  preferred  securities  of that AES Trust pro rata
according to the aggregate  liquidation amount of the preferred  securities held
by the relevant  holder in relation to the aggregate  liquidation  amount of all
the  preferred  securities  of  that  AES  Trust  outstanding,  and  only  after
satisfaction of all amounts owed to the holders of such preferred securities, to
each holder of common  securities  of that AES Trust pro rata  according  to the
aggregate  liquidation  amount of those common  securities  held by the relevant
holder in relation to the aggregate  liquidation amount of all common securities
of that AES Trust outstanding.

EVENTS OF DEFAULT

       If an Indenture Event of Default occurs and is continuing with respect to
junior  subordinated  debt trust  securities  deposited in an AES Trust as trust
assets,  an Event of Default  under the  Declaration  (a  "Declaration  Event of
Default")  of that AES Trust will occur and be  continuing  with  respect to any
outstanding  Trust Securities of that AES Trust. In such event, each Declaration
provides that the holders of common  securities of that AES Trust will be deemed
to have  waived  any  Declaration  Event of Default  with  respect to the common
securities until all Declaration Events of Default with respect to the preferred
securities  of that AES Trust have been cured or waived.  Until all  Declaration
Events of Default with  respect to the  preferred  securities  of that AES Trust
have been so cured or waived,  the Property  Trustee will be deemed to be acting
solely on behalf of the holders of the  preferred  securities  of that AES Trust
and only the holders of such preferred  securities will have the right to direct
the Property  Trustee with respect to certain matters under such Declaration and
consequently under the Indenture. In the event


                                       21
<PAGE>

that any Declaration  Event of Default with respect to the preferred  securities
of such AES Trust is waived by the holders of the  preferred  securities of that
AES Trust as  provided  in the  Declaration,  the  holders of common  securities
pursuant to the  Declaration  have agreed  that the waiver  also  constitutes  a
waiver of the Declaration Event of Default with respect to the common securities
for all purposes under the Declaration  without any further act, vote or consent
of the holders of the common securities.


RECORD HOLDERS

       Each Declaration provides that the trustees of an AES Trust may treat the
person in whose name a  certificate  representing  its  preferred  securities is
registered  on the books and records of an AES Trust as the sole holder  thereof
and of the preferred  securities  represented  thereby for purposes of receiving
distributions and for all other purposes and, accordingly, shall not be bound to
recognize any equitable or other claim to or interest in such  certificate or in
the preferred securities  represented thereby on the part of any person, whether
or not that AES Trust  shall  have  actual or other  notice  thereof.  Preferred
securities will be issued in fully registered form.  Unless otherwise  specified
in a prospectus supplement, preferred securities will be represented by a global
certificate registered on the books and records of such AES Trust in the name of
a depositary  named in an  accompanying  prospectus  supplement  or its nominee.
Under each Declaration:

       o  that AES Trust and the trustees thereof shall be entitled to deal with
          the  depositary  (or  any  successor  depositary)  for  all  purposes,
          including the payment of distributions and receiving approvals,  votes
          or consents under the related Declaration,  and except as set forth in
          the related  Declaration with respect to the Property  Trustee,  shall
          have  no  obligation  to  persons  owning  a  beneficial  interest  in
          preferred   securities   ("Preferred   Security   Beneficial  Owners")
          registered  in the name of and held by the  depositary or its nominee;
          and

       o  the rights of Preferred Security  Beneficial Owners shall be exercised
          only through the depositary (or any successor depositary) and shall be
          limited  to those  established  by law and  agreements  between  those
          Preferred  Security  Beneficial  Owners and the  depositary  andor its
          participants.  With respect to preferred securities  registered in the
          name of and held by the  depositary  or its  nominee,  all notices and
          other  communications  required under each Declaration  shall be given
          to, and all distributions on those preferred securities shall be given
          or made to, the depositary (or its successor).


       The  specific  terms of the  depositary  arrangement  with respect to the
preferred securities will be disclosed in the applicable prospectus supplement.

DEBTS AND OBLIGATIONS

       In each Declaration,  we have agreed to pay for all debts and obligations
(other than with respect to the Trust  Securities) and all costs and expenses of
the  applicable  AES Trust,  including the fees and expenses of its trustees and
any taxes and all costs and  expenses  with respect  thereto,  to which that AES
Trust may become  subject,  except  for United  States  withholding  taxes.  The
foregoing  obligations  under each Declaration are for the benefit of, and shall
be  enforceable  by,  any  person to whom any such  debts,  obligations,  costs,
expenses  and taxes are owed (a  "Creditor")  whether or not that  Creditor  has
received  notice  thereof.  Any Creditor may enforce these  obligations  of ours
directly  against  us and we have  irrevocably  waived  any  right or  remedy to
require  that any  Creditor  take any action  against any AES Trust or any other
person  before  proceeding  against AES. We have agreed in each  Declaration  to
execute additional  agreements as may be necessary or desirable in order to give
full effect to the foregoing.

                    DESCRIPTION OF THE PREFERRED SECURITIES


       Each AES Trust may issue, from time to time, only one series of preferred
securities having terms described in the prospectus supplement relating thereto.
The  Declaration of each AES Trust  authorizes the Regular  Trustees of that AES
Trust to issue on behalf of that AES Trust one series of  preferred  securities.
Each  Declaration  will be qualified as an indenture  under the Trust  Indenture
Act.  The  preferred  securities  will  have  terms,  including   distributions,
redemption,  voting,  liquidation  rights and such other preferred,  deferred or
other  special  rights  or  restrictions  as shall be set  forth in the  related
Declaration  or made  part of  that  Declaration  by the  Trust  Indenture  Act.
Reference  is  made  to the  prospectus  supplement  relating  to the  preferred
securities of an AES Trust for specific terms, including


       o  the specific designation of the preferred securities,


       o  the number of preferred securities issued by the AES Trust,


       o  the annual  distribution  rate (or method of calculation  thereof) for
          preferred  securities issued by such AES Trust, the date or dates upon
          which such distributions shall be payable and the record date or dates
          for the payment of such distributions,


       o  whether  distributions on preferred securities issued by the AES Trust
          shall be cumulative,  and, in the case of preferred  securities having
          cumulative  distribution  rights,  the  date or  dates  or  method  of
          determining  the date or dates from which  distribution  on  preferred
          securities issued by that AES Trust shall be cumulative,


       o  the amount or amounts which shall be paid out of the assets of the AES
          Trust to the holders of  preferred  securities  of that AES Trust upon
          voluntary or  involuntary  dissolution,  winding-up or  termination of
          that AES Trust,


       o  the  obligation  or right,  if any,  of the AES Trust to  purchase  or
          redeem preferred  securities issued by that AES Trust and the price or
          prices at which,  the period or periods within which and the terms and
          conditions  upon which  preferred  securities  issued by the AES Trust
          shall or may be purchased or redeemed,  in whole or in part,  pursuant
          to that obligation or right,


       o  the voting rights,  if any, of preferred  securities issued by the AES
          Trust in addition to those  required by law,  including  the number of
          votes per Preferred  Security and any  requirement for the approval by
          the holders of preferred securities, or of preferred securities issued
          by one or more AES Trusts,  or of both,  as a condition  to  specified
          actions or amendments to the Declaration of that AES Trust,



       o  terms for any conversion or exchange into other securities and


       o  any other relevant  rights,  preferences,  privileges,  limitations or
          restrictions  of  preferred   securities   issued  by  the  AES  Trust
          consistent  with the  Declaration of that AES Trust or with applicable
          law.


       All preferred  securities  offered hereby will be guaranteed by us as and
to the extent set forth below under  "Description  of the  Preferred  Securities
Guarantees." Certain United States federal income tax considerations  applicable
to any offering of  preferred  securities  will be  described in the  prospectus
supplement relating thereto.


       In connection with the issuance of preferred  securities,  each AES Trust
will issue one series of common  securities.  The  Declaration of each AES Trust
authorizes  the  Regular  Trustees  of that trust to issue on behalf of that AES
Trust one series of common securities having such terms including distributions,
redemption,  voting,  liquidation  rights or such  restrictions  as shall be set
forth therein. The terms of the common securities issued by an AES Trust will be
substantially  identical to the terms of the preferred securities issued by that
AES Trust and the common  securities will rank pari passu,  and payments will be
made thereon on a Pro Rata Basis with the preferred  securities except that if a
Declaration Event of Default occurs and is continuing, the rights of the holders
of such common  securities to payment in respect of  distributions  and payments
upon liquidation, redemption and maturity will be subordinated to


                                       23
<PAGE>

the  rights of the  holders  of those  preferred  securities.  Except in certain
limited  circumstances,  the common  securities issued by an AES Trust will also
carry the right to vote and to appoint, remove or replace any of the trustees of
that AES Trust. All of the common securities of an AES Trust will be directly or
indirectly owned by AES.

              DESCRIPTION OF THE PREFERRED SECURITIES GUARANTEES

       Below is a summary of  information  concerning  the preferred  securities
guarantees  that will be  executed  and  delivered  by us for the benefit of the
holders  from time to time of  preferred  securities.  Each  preferred  security
guarantee will be separately qualified under the Trust Indenture Act and will be
held by The First  National  Bank of Chicago  (or such  other  trustee as may be
designated  by the  Company),  acting in its capacity as indenture  trustee with
respect thereto,  for the benefit of holders of the preferred  securities of the
applicable AES Trust. The terms of each preferred  securities  guarantee will be
those set forth in each  preferred  securities  guarantee and those made part of
that  guarantee by the Trust  Indenture  Act. This  description  summarizes  the
material  terms of the preferred  securities  guarantees and is qualified in its
entirety by reference to the form of preferred  securities  guarantee,  which is
filed as an exhibit to the registration statement of which this prospectus forms
a part, and the Trust Indenture Act. Section and Article  references used herein
are references to the provisions of the form of preferred securities guarantee.

GENERAL

       Pursuant to each preferred securities guarantee,  we will irrevocably and
unconditionally  agree, to the extent set forth therein,  to pay in full, to the
holders  of the  preferred  securities  issued by an AES  Trust,  the  Guarantee
Payments (as defined herein) (without duplication of amounts theretofore paid by
that AES  Trust),  to the extent not paid by that AES Trust,  regardless  of any
defense, right of set-off or counterclaim that the AES Trust may have or assert.
The following  payments or  distributions  with respect to preferred  securities
issued by an AES  Trust to the  extent  not paid or made by that AES Trust  (the
"Guarantee  Payments"),  will be subject to the preferred  securities  guarantee
(without duplication):

       o  any accrued and unpaid  distributions  on those preferred  securities,
          and  the   redemption   price,   including   all  accrued  and  unpaid
          distributions to the date of redemption, with respect to any preferred
          securities  called for redemption by that AES Trust but if and only to
          the  extent  that in each case we have made a payment  to the  related
          Property  Trustee of interest or principal on the junior  subordinated
          debt trust securities deposited in that AES Trust as trust assets and

       o  upon a voluntary or involuntary dissolution, winding-up or termination
          of that AES Trust (other than in connection  with the  distribution of
          that  junior  subordinated  debt trust  securities  to the  holders of
          preferred  securities  or the  redemption  of  all  of  the  preferred
          securities upon the maturity or redemption of such junior subordinated
          debt trust securities) the lesser of

       o  the  aggregate  of  the liquidation  amount and all accrued and unpaid
          distributions  on  that preferred  securities to the  date of payment,
          to the extent that AES Trust has funds available therefor or

       o  the  amount  of  assets of that  AES  Trust  remaining  available  for
          distribution  to holders  of  such Preferred Securities in liquidation
          of that AES Trust.

       Our  obligation  to make a Guarantee  Payment may be  satisfied by direct
payment of the required amounts by us to the holders of preferred  securities or
by causing the applicable AES Trust to pay those amounts to those holders.

       The  preferred  securities  guarantee  is a  guarantee  from  the time of
issuance of the applicable  preferred  securities,  but the preferred securities
guarantee covers  distributions and other payments on those preferred securities
only if and to the extent that we have made a payment to the Property Trustee of
interest or principal on the junior subordinated debt trust securities deposited
in the applicable AES Trust as trust assets. If we do not make interest or


                                       24
<PAGE>

principal payments on the junior subordinated debt trust securities deposited in
the  applicable  AES Trust as trust assets,  the Property  Trustee will not make
distributions  of the  preferred  securities of that AES Trust and the AES Trust
will not have funds available therefor.


       Our  obligations  under the  Declaration  for each Trust,  the  preferred
securities  guarantee issued with respect to preferred securities issued by that
Trust, the junior subordinated debt trust securities purchased by that Trust and
the related  Indenture (as defined  below) in the aggregate  will provide a full
and unconditional guarantee on a subordinated basis by us of payments due on the
preferred securities issued by that Trust.

CERTAIN COVENANTS OF AES

       In each preferred securities guarantee, we will covenant that, so long as
any preferred  securities issued by the applicable AES Trust remain outstanding,
we will not


       o  declare or pay any dividends on, or redeem, purchase,  acquire or make
          a  distribution  or  liquidation  payment  with respect to, any of our
          common stock or  preferred  stock or make any  guarantee  payment with
          respect thereto or


      o   make any payment of  interest,  premium (if any) or  principal  on any
          debt  trust  securities  issued by us which  rank pari  passu  with or
          junior to the junior  subordinated debt trust  securities,  if at such
          time


      o   we are in default  with  respect to our  Guarantee  Payments  or other
          payment obligations under the preferred securities guarantee,


      o   there shall have occurred any  Declaration  Event of Default under the
          related Declaration or


      o   in the event that junior subordinated debt trust securities are issued
          to an AES Trust in connection with the issuance of Trust Securities by
          that AES Trust,  we shall have given  notice of our  election to defer
          payments  of  interest  on  these  junior   subordinated   debt  trust
          securities by extending the interest payment period as provided in the
          terms  of the  junior  subordinated  debt  trust  securities  and such
          period, or any extension thereof, is continuing: provided that

                     --    we will be  permitted to pay accrued  dividends  (and
                           cash  in  lieu  of   fractional   shares)   upon  the
                           conversion of Preferred  Stock as may be  outstanding
                           from time to time,  in each case in  accordance  with
                           the terms of such stock and

                    --     the foregoing will not apply to stock dividends  paid
                           by us.

       In  addition,  so long as any preferred securities remain outstanding, we
have agreed

       o  to remain the sole direct or indirect owner of all of the  outstanding
          common  securities  issued by the  applicable  AES Trust and shall not
          cause or permit the common securities to be transferred  except to the
          extent  permitted  by  the  related  Declaration;  provided  that  any
          permitted  successor  of ours under the  Indenture  may succeed to our
          ownership of the common  securities issued by the applicable AES Trust
          and

       o  to use  reasonable  efforts to cause that AES Trust to  continue to be
          treated  as a grantor  trust for  United  States  federal  income  tax
          purposes   except  in  connection   with  a  distribution   of  junior
          subordinated debt trust securities.


AMENDMENTS AND ASSIGNMENT

       Except  with  respect to any  changes  that do not  adversely  affect the
rights of  holders of  preferred  securities  (in which case no consent  will be
required),  each  preferred  securities  guarantee  may be amended only with the
prior approval of the holders of not less than 66 23% in  liquidation  amount of
the outstanding  preferred  securities  issued by the applicable AES Trust.  The
manner of obtaining an approval of holders of the preferred  securities  will be
described  in  an  accompanying   prospectus  supplement.   All  guarantees  and
agreements  contained  in  a  preferred  securities  guarantee  shall  bind  the
successors,  assignees, receivers, trustees and representatives of AES and shall
inure  to  the  benefit  of  the  holders  of the  preferred  securities  of the
applicable AES Trust


                                       25

then  outstanding.  Except in connection  with a  consolidation,  merger or sale
involving  AES that is  permitted  under the  Indenture,  we may not  assign its
obligations under any preferred securities guarantee.


TERMINATION OF THE PREFERRED SECURITIES GUARANTEES

       Each preferred  securities  guarantee will terminate and be of no further
force and effect as to the preferred  securities  issued by the  applicable  AES
Trust upon full payment of the redemption  price of all preferred  securities of
that AES  Trust,  or upon  distribution  of the junior  subordinated  debt trust
securities  to the  holders  of the  preferred  securities  of that AES Trust in
exchange for all of the preferred  securities  issued by that AES Trust, or upon
full  payment  of the  amounts  payable  upon  liquidation  of that  AES  Trust.
Notwithstanding the foregoing, each preferred securities guarantee will continue
to be  effective or will be  reinstated,  as the case may be, if at any time any
holder of preferred  securities  issued by the applicable AES Trust must restore
payment of any sums paid under such preferred securities or such guarantee.

STATUS OF THE PREFERRED SECURITIES GUARANTEES

       Our  obligations  under each preferred  securities  guarantee to make the
Guarantee Payments will constitute an unsecured obligation of ours and will rank

       o  subordinate  and  junior  in  right  of  payment  to all of our  other
          liabilities,  including the junior subordinated debt trust securities,
          except those made pari passu or subordinate by their terms, and

       o  senior to all capital  stock now or hereafter  issued by us and to any
          guarantee nor or hereafter entered into by us in respect of any of our
          capital  stock.  Our  obligations  under  each  preferred   securities
          guarantee  will rank pari passu with each other  preferred  securities
          guarantee.  Because we are a holding  company,  our obligations  under
          each preferred securities guarantee are also effectively  subordinated
          to all existing and future liabilities,  including trade payables,  of
          our  subsidiaries,  except to the extent that we are a creditor of the
          subsidiaries  recognized as such. Each Declaration  provides that each
          holder of preferred  securities  issued by the applicable AES Trust by
          acceptance  thereof agrees to the  subordination  provisions and other
          terms of the related preferred securities guarantee.

       Each  preferred  securities  guarantee  will  constitute  a guarantee  of
payment and not of  collection  (that is, the  guaranteed  party may institute a
legal proceeding  directly against the guarantor to enforce its rights under the
guarantee without first instituting a legal proceeding  against any other person
or entity). Each preferred securities guarantee will be deposited with The First
National Bank of Chicago,  as indenture  trustee,  to be held for the benefit of
the holders of the preferred  securities issued by the applicable AES Trust. The
First National Bank of Chicago shall enforce the preferred  securities guarantee
on behalf of the holders of the preferred  securities  issued by the  applicable
AES Trust.  The  holders of not less than a majority  in  aggregate  liquidation
amount of the preferred  securities  issued by the applicable AES Trust have the
right to direct the time,  method and place of conducting any proceeding for any
remedy  available  in respect of the  related  preferred  securities  guarantee,
including the giving of  directions  to The First  National Bank of Chicago . If
The First  National Bank of Chicago fails to enforce such  preferred  securities
guarantee as above provided,  any holder of preferred  securities  issued by the
applicable  AES Trust may institute a legal  proceeding  directly  against us to
enforce its rights under such  preferred  securities  guarantee,  without  first
instituting a legal  proceeding  against the  applicable  AES Trust or any other
person or entity.  Notwithstanding  the  foregoing,  if we have failed to make a
guarantee  payment,  a holder of preferred  securities may directly  institute a
proceeding against us for enforcement of the preferred  securities guarantee for
that payment.


                                       26

MISCELLANEOUS

       We will be required to provide  annually  to The First  National  Bank of
Chicago a statement as to the  performance  by us of certain of our  obligations
under  the  preferred  securities  guarantees  and as to  any  default  in  such
performance.  We are required to file annually  with The First  National Bank of
Chicago an officer's  certificate as to our compliance with all conditions under
the preferred securities guarantees.

       The First National Bank of Chicago, prior to the occurrence of a default,
undertakes  to perform  only those duties as are  specifically  set forth in the
applicable  preferred  securities guarantee and, after default with respect to a
preferred  securities  guarantee,  shall  exercise  the same degree of care as a
prudent  individual  would  exercise in the  conduct of his or her own  affairs.
Subject  to such  provision,  The First  National  Bank of  Chicago  is under no
obligation to exercise any of the powers vested in it by a preferred  securities
guarantee  at the  request of any holder of  preferred  securities  unless it is
offered  reasonable  indemnity against the costs,  expenses and liabilities that
might be incurred thereby.

GOVERNING LAW

       The Guarantees will be governed by, and construed in accordance with, the
laws of the State of New York.

         DESCRIPTION OF THE JUNIOR SUBORDINATED DEBT TRUST SECURITIES

       Junior subordinated debt trust securities may be issued from time to time
in one or more series under an Indenture  (the  "Indenture")  between us and The
First National Bank of Chicago, as trustee (the "Indenture  Trustee").  The form
of junior  subordinated  debt trust  securities  indenture  has been filed as an
exhibit to the Registration Statement of which this prospectus forms a part. The
following  description  summarizes the material  terms of the Indenture,  and is
qualified in its entirety by reference to the Indenture and the Trust  Indenture
Act.  Whenever  particular  provisions  or defined  terms in the  Indenture  are
referred  to  in  this  prospectus,   those  provisions  or  defined  terms  are
incorporated by reference in this prospectus. Section and article references are
references to provisions of the Indenture.

GENERAL

       The junior  subordinated debt trust securities will be unsecured,  junior
subordinated  obligation  of AES.  The  Indenture  does not limit the  amount of
additional  indebtedness we or any of our subsidiaries may incur. Since we are a
holding  company,  our  rights and the rights of our  creditors,  including  the
holders of junior  subordinated  debt trust  securities,  to  participate in the
assets of any subsidiary upon the latter's liquidation or recapitalization  will
be  subject to the prior  claims of the  subsidiary's  creditors,  except to the
extent that we may ourselves be a creditor with  recognized  claims  against the
subsidiary.

       The  Indenture  does  not  limit  the  aggregate   principal   amount  of
indebtedness   which  may  be  issued   thereunder   and  provides  that  junior
subordinated debt trust securities may be issued thereunder from time to time in
one or more series.  The junior  subordinated debt trust securities are issuable
in one or more series pursuant to an indenture supplemental to the Indenture.

       In the event junior  subordinated  debt trust securities are issued to an
AES Trust or a Trustee of such trust in  connection  with the  issuance of Trust
Securities by that AES Trust,  those junior  subordinated  debt trust securities
subsequently  may  be  distributed  pro  rata  to the  holders  of  these  Trust
Securities  in  connection  with  the  dissolution  of such AES  Trust  upon the
occurrence of certain events described in the prospectus  supplement relating to
such  Trust  Securities.  Only one  series of  junior  subordinated  debt  trust
securities  will be  issued  to an AES  Trust  or a  trustee  of such  trust  in
connection with the issuance of Trust Securities by such AES Trust.

       Reference is made to the prospectus  supplement which will accompany this
prospectus  for the following  terms of the series of junior  subordinated  debt
trust  securities being offered thereby (to the extent such terms are applicable
to the junior subordinated debt trust securities):

          securities  will bear interest or the method of calculating  such rate

       o  the date or dates from  which  interest  shall  accrue,  the  interest
          payment  dates on which  interest  will be  payable  or the  manner of

          the  determination  of  holders  to whom  interest  is  payable on any
          interest payment dates;

       o  the right,  if  any,  to  extend  the interest payment periods and the
          duration of the extension;

          which, the price or prices at which, and the terms and conditions upon

          amounts on the junior  subordinated  debt trust  securities  held by a
          person who is not a U.S.  person in respect of any tax,  assessment or
          governmental  charge  withheld or deducted and, if so, whether we will

          provided for with respect to such series,  including any  modification
          of or  additions  to the events of default or  covenants  provided for
          with respect to the junior subordinated debt trust securities, and any
          terms which may be required by or advisable  under  applicable laws or
          regulations not inconsistent with the Indenture; and

       o  whether the junior  subordinated debt trust securities are issuable as

integral  multiples  thereof.  Junior  subordinated debt trust securities may be
presented  for  exchange  and  junior  subordinated  debt  trust  securities  in
registered  form may be presented for transfer in the manner,  at the places and
subject  to the  restrictions  set forth in the junior  subordinated  debt trust
securities  and the  prospectus  supplement.  These  services  will be  provided
without  charge,  other  than any tax or other  governmental  charge  payable in
connection  therewith,  but  subject to the  limitations  provided in the junior
subordinated debt trust securities. Junior subordinated debt trust securities in
bearer form and the coupons, if any,  appertaining  thereto will be transferable

<PAGE>

Junior  subordinated debt trust securities  bearing no interest or interest at a
rate that at the time of  issuance is below the  prevailing  market rate will be
sold at a discount below their stated  principal  amount.  Special United States
federal  income  tax   considerations   applicable  to  any  discounted   junior
subordinated debt trust securities or to certain junior  subordinated debt trust
securities  issued at par which are  treated as having been issued at a discount
for United States  federal income tax purposes will be described in the relevant
prospectus supplement.


                     CERTAIN COVENANTS OF AES APPLICABLE TO
                 THE JUNIOR SUBORDINATED DEBT TRUST SECURITIES

       If junior  subordinated  debt trust securities are issued to an AES Trust
in connection  with the issuance of Trust  Securities by that AES Trust, we will
covenant in the Indenture  that, so long as the preferred  securities  issued by
the  applicable  AES Trust  remain  outstanding,  we will not declare or pay any
dividends on, or redeem, purchase, acquire or make a distribution or liquidation
payment with respect to, any of its common stock or preferred  stock or make any
guarantee payment with respect to, any of its common stock or preferred stock or
make any guarantee payment with respect thereto if at that time

       o  we are in default  with  respect to our  Guarantee  Payments  or other
          payment obligations under the related preferred securities guarantee,

       o  there shall have occurred any Indenture  Event of Default with respect
          to the junior subordinated debt trust securities or

       o  in the event that junior subordinated debt trust securities are issued
          to an AES Trust in connection with the issuance of Trust Securities by
          that AES Trust,  we shall have given  notice of our  election to defer
          payments  of  interest  on  those  junior   subordinated   debt  trust
          securities by extending the interest payment period as provided in the
          terms of those  junior  subordinated  debt trust  securities  and that
          period, or any extension thereof, is continuing; provided that

      o   we will be  permitted  to pay accrued  dividends  (and cash in lieu of
          fractional  shares) upon the conversion of any of our preferred  stock
          as may be  outstanding  from time to time,  in each case in accordance
          with the terms of such stock and

      o   the foregoing will not apply to any stock dividends paid by us.

       In addition,  if junior  subordinated debt trust securities are issued to
an AES Trust in  connection  with the issuance of Trust  Securities  by that AES
Trust,  for so long as the preferred  securities  issued by the  applicable  AES
Trust remain outstanding, we have agreed

      o   to remain the sole direct or indirect owner of all of the  outstanding
          common  securities issued by the applicable AES Trust and not to cause
          or permit the common securities to be transferred except to the extent
          permitted  by the related  Declaration;  provided  that any  permitted
          successor of AES under the  Indenture  may succeed to our ownership of
          the common securities issued by the applicable AES Trust,

      o   to comply fully with all of its obligations  and agreements  contained
          in the related Declaration and

      o   not to take any action which would cause the  applicable  AES Trust to
          cease to be  treated  as a grantor  trust for  United  States  federal
          income tax  purposes,  except in  connection  with a  distribution  of
          junior subordinated debt trust securities.


SUBORDINATION

       The payment of principal of, premium,  if any, and interest on the junior
subordinated  debt trust  securities  will,  to the extent and in the manner set
forth in the Indenture, be subordinated in right of payment to the prior payment
in full, in cash or cash  equivalents,  of all senior and  subordinated  debt of
AES.

       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 of


                                       29
<PAGE>

us, 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 trust  securities  will be entitled to
receive any payment in respect of the principal of, premium, if any, or interest
on the junior subordinated debt trust securities.

       No  payments  on account of  principal,  premium,  if any, or interest in
respect of the junior  subordinated  debt trust  securities may be made by us if
there  shall have  occurred  and be  continuing  a default in any  payment  with
respect to senior and subordinated  debt or during certain periods when an event
of default  under  certain  senior and  subordinated  debt  permits  the lenders
thereunder to accelerate the maturity of such senior and  subordinated  debt. 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,  from and after the
date of receipt by the Trustee of written notice from holders of such designated
senior and  subordinated  debt or from an agent of such holders,  no payments on
account of  principal,  premium,  if any,  or  interest in respect of the junior
subordinated  debt  trust  securities  may be made by us  during a  period  (the
"Payment Blockage Period") commencing on the date of delivery of such notice and
ending  179  days  thereafter  (unless  the  Payment  Blockage  Period  shall be
terminated by written  notice to the Trustee from the holders of the  designated
senior and subordinated debt or from an agent of such holders,  or such 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
trust securities  during any period of 360 consecutive days. No event of default
which existed or was continuing on the date of the  commencement  of any payment
blockage  period with respect to the  designated  senior and  subordinated  debt
initiating  such payment  blockage  period shall be or be made the basis for the
commencement  of any subsequent  payment  blockage period by the holders of such
designated senior and subordinated debt, unless such event of default shall have
been cured or waived for a period of not less than 90 consecutive days.

       By reason of this subordination,  in the event of insolvency,  funds that
would  otherwise  be  payable  to  holders  of junior  subordinated  debt  trust
securities  will be paid to the holders of our senior and  subordinated  debt to
the  extent  necessary  to pay that  debt in full,  and we may be unable to meet
fully our  obligations  with  respect  to the  junior  subordinated  debt  trust
securities.

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

       o  all indebtedness for borrowed money;

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

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

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

       o  all obligations as lessee under capitalized leases;

       o  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;

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

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

       o  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:

       o  Debt  under  the  Credit  Agreement  dated as of  August  2, 1996 (the
          "Credit Agreement") among The AES


                                       30
<PAGE>

          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

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

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

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

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

       o  Debt to any Affiliate,

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

       o  any  other  Debt  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 trust securities, and
          in particular the junior subordinated debt trust securities shall rank
          pari passu with all other debt trust securities and guarantees  issued
          to any trust,  partnership or other entity affiliated with us which is
          a financing  vehicle of us in connection with an issuance of preferred
          securities by such financing entity, and

       o  our redeemable stock.


INDENTURE EVENTS OF DEFAULT

       The Indenture  provides  that any one or more of the following  described
events, which has occurred and is continuing, constitutes an "Indenture Event of
Default"  with  respect  to  each  series  of  junior  subordinated  debt  trust
securities:

       o  failure for 30 days to pay  interest on the junior  subordinated  debt
          trust  securities  of that  series  when  due;  provided  that a valid
          extension of the interest  payment period by us shall not constitute a
          default in the payment of interest for this purpose;

       o  failure  to pay  principal  of or  premium,  if  any,  on  the  junior
          subordinated  debt trust securities of such series when due whether at
          maturity, upon redemption, by declaration or otherwise;

       o  failure  to observe or perform  any other  covenant  contained  in the
          Indenture with respect to such series for 90 days after written notice
          to us from the  Indenture  Trustee  or the  holders of at least 25% in
          principal  amount of the outstanding  junior  subordinated  debt trust
          securities of such series; or

       o  certain events in bankruptcy, insolvency or reorganization of AES.

       In each and every  such  case,  unless  the  principal  of all the junior
subordinated  debt trust securities of that series shall have already become due
and payable, either the Indenture Trustee or the holders of not less than 25% in
aggregate  principal amount of the junior  subordinated debt trust securities of
that series then  outstanding,  by notice in writing to us (and to the Indenture
Trustee if given by such  holders),  may declare the principal of all the junior
subordinated  debt  trust  securities  of  that  series  to be due  and  payable
immediately,  and upon any such  declaration  the same shall become and shall be
immediately due and payable.

       The holders of a majority in aggregate  outstanding  principal  amount of
the junior  subordinated  debt trust securities of that series have the right to
direct the time,  method and place of conducting  any  proceeding for any remedy
available to the Indenture Trustee.  The Indenture Trustee or the holders of not
less  than  25%  in  aggregate   outstanding  principal  amount  of  the  junior
subordinated  debt trust securities of that series may declare the principal due
and payable  immediately upon an Indenture Event of Default with respect to such
series, but the holders of a majority in aggregate  outstanding principal amount
of junior  subordinated  debt  trust  securities  of such  series may annul such
declaration  and waive  the  default  if the  default  has been  cured and a sum
sufficient to pay all matured  installments of interest and principal  otherwise
than by  acceleration  and any premium  has been  deposited  with the  Indenture
Trustee.

       The holders of a majority in aggregate  outstanding  principal  amount of
the junior  subordinated  debt trust securities of that series may, on behalf of
the holders of all the junior subordinated debt trust securities of that series,
waive any past default,  except a default in the payment of principal,  premium,
if any, or interest  (unless such default has been cured and a sum sufficient to
pay all  matured  installments  of  interest  and  principal  otherwise  than by
acceleration and any premium has been deposited with the Indenture Trustee) or a
call for  redemption  of  junior  subordinated  debt  trust  securities.  We are
required to file annually with the Indenture Trustee a certificate as to whether
or not we are in compliance  with all the  conditions  and  covenants  under the
Indenture.

       If junior  subordinated  debt trust securities are issued to an AES Trust
in  connection  with the issuance of Trust  Securities  of such AES Trust,  then
under the applicable  Declaration an Indenture  Event of Default with respect to
such series of junior  subordinated  debt trust  securities  will  constitute  a
Declaration Event of Default.

MODIFICATION OF THE INDENTURE

       The  Indenture  contains  provisions  permitting  us  and  the  Indenture
Trustee,  with the  consent  of the  holders  of not  less  than a  majority  in
principal amount of the outstanding junior subordinated debt trust securities of
each series  affected,  to modify the  Indenture or any  supplemental  indenture
affecting  the rights of the  holders  of such  junior  subordinated  debt trust
securities;  provided that no such  modification may, without the consent of the
holder of each  outstanding  junior  subordinated  debt trust security  affected
thereby,

       o  extend  the fixed  maturity  of any  junior  subordinated  debt  trust
          securities of any series, reduce the principal amount thereof,  reduce
          the rate or extend the time of payment of interest thereon, reduce any
          premium  payable upon the redemption  thereof,  without the consent of
          the holder of each junior subordinated debt trust security so affected
          or


       o  reduce the percentage of junior  subordinated  debt trust  securities,
          the holders of which are required to consent to any such modification,
          without the consent of the  holders of each junior  subordinated  debt
          trust security then outstanding and affected thereby.

BOOK-ENTRY AND SETTLEMENT

       If any junior  subordinated  debt  preferred  securities  of a series are
represented by one or more global  securities (each, a "Global  Security"),  the
applicable prospectus supplement will describe the circumstances,  if any, under
which  beneficial  owners of interests in any such Global  Security may exchange
such interests for junior  subordinated debt trust securities of such series and
of like tenor and  principal  amount in any  authorized  form and  denomination.
Principal of and any premium and interest on a Global  Security  will be payable
in the manner described in the applicable prospectus supplement.

       The  specific  terms of the  depositary  arrangement  with respect to any
portion  of a  series  of  junior  subordinated  debt  trust  securities  to  be
represented by a Global Security will be described in the applicable  prospectus
supplement.

CONSOLIDATION, MERGER AND SALE

       The Indenture will provide that we may not consolidate with or merge into
any other person or transfer or lease its properties and assets substantially as
an  entirety  to any  person  and may not  permit  any  person to merge  into or
consolidate with us unless

       o  either AES will be the resulting or surviving  entity or any successor
          or purchaser is a corporation  organized  under the laws of the United
          States of America, any State or the District of Columbia, and any such
          successor or purchaser  expressly  assumes our  obligations  under the
          Indenture and

       o  immediately after giving effect to the transaction no Event of Default
          shall have occurred and be continuing.

DEFEASANCE AND DISCHARGE

       Under the terms of the Indenture,  we will be discharged from any and all
obligations  in respect of the junior  subordinated  debt trust  securities of a
series (except in each case for certain  obligations to register the transfer or
exchange of such junior subordinated debt trust securities,


                                       32
<PAGE>

replace stolen,  lost or mutilated junior  subordinated debt trust securities of
that series, maintain paying agencies and hold moneys for payment in trust) if

       o  we  irrevocably  deposit  with  the  Indenture  Trustee  cash  or U.S.
          Government  Obligations,  as trust funds in an amount  certified to be
          sufficient to pay at maturity (or upon  redemption)  the principal of,
          premium,  if any, and interest on all outstanding junior  subordinated
          debt trust securities of such series;

       o  this  deposit  will  not  result  in a  breach  or  violation  of,  or
          constitute a default  under,  any  agreement or instrument to which we
          are a party or by which we are bound;

       o  we  deliver  to the  Indenture  Trustee  an  opinion of counsel to the
          effect  that  the  holders  of  the  junior  subordinated  debt  trust
          securities of that series will not recognize income,  gain or loss for
          United  States  federal  income  tax  purposes  as a  result  of  that
          defeasance  and that  defeasance  will not  otherwise  alter  holders'
          United States federal  income tax treatment of principal,  premium and
          interest  payments on those junior  subordinated debt trust securities
          of that series (such opinion must be based on a ruling of the Internal
          Revenue  Service or a change in United States  federal  income tax law
          occurring  after  the  date of that  junior  subordinated  debt  trust
          securities  indenture,  since  such a result  would  not  occur  under
          current tax law);

       o  we have  delivered to the Indenture  Trustee an Officer's  Certificate
          and an opinion of counsel,  each stating that all conditions precedent
          provided for relating to the defeasance contemplated by such provision
          have been complied with; and

       o  no event or condition shall exist that,  pursuant to the subordination
          provisions  applicable  to such series,  would  prevent us from making
          payments of principal of, premium,  if any, and interest on the junior
          subordinated  debt trust  securities of such series at the date of the
          irrevocable deposit referred to above.

GOVERNING LAW

       The Indenture and the junior  subordinated  debt trust securities will be
governed by the laws of the State of New York.

INFORMATION CONCERNING THE INDENTURE TRUSTEE

       The Indenture Trustee, prior to default,  undertakes to perform only such
duties as are specifically set forth in the Indenture and, after default,  shall
exercise the same degree of care as a prudent  individual  would exercise in the
conduct of his or her own  affairs.  Subject to such  provision,  the  Indenture
Trustee is under no obligation to exercise any of the powers vested in it by the
junior subordinated debt trust securities indenture at the request of any holder
of  junior  subordinated  debt  trust  securities,   unless  offered  reasonable
indemnity by such holder against the costs,  expenses and liabilities that might
be incurred thereby. The Indenture Trustee is not required to expend or risk its
own funds or otherwise incur personal financial  liability in the performance of
its  duties if the  Trustee  reasonably  believes  that  repayment  or  adequate
indemnity is not reasonably assured to it.

       AES  and  our   subsidiaries   maintain   ordinary   banking   and  trust
relationships with The First National Bank of Chicago and its affiliates.

MISCELLANEOUS

       We will  have the  right at all  times to  assign  any of our  rights  or
obligations under the Indenture to a direct or indirect wholly-owned  subsidiary
of ours;  provided  that,  in the event of any such  assignment,  we will remain
jointly and severally liable for all such obligations. Subject to the foregoing,
the  Indenture  will be binding  upon and inure to the  benefit  of the  parties
thereto and their respective successors and assigns. The Indenture provides that
it may not  otherwise be assigned by the parties  thereto  other than by us to a
successor or purchaser pursuant to a consolidation,  merger or sale permitted by
the Indenture.

                             PLAN OF DISTRIBUTION

the AES Trusts may sell the preferred  securities being offered hereby in any of

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

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

payment and delivery on a specified date in the future.  These contracts will be
