PROSPECTUS
JANUARY 23, 1998


[GRAPHIC OMITTED]


              THE AES CORPORATION



     OFFER TO EXCHANGE 8.50% SENIOR SUBORDINATED EXCHANGE NOTES DUE 2007 FOR ANY
AND ALL  OUTSTANDING  8.50% SENIOR  SUBORDINATED  NOTES DUE 2007 AND TO EXCHANGE
8.875%  SENIOR  SUBORDINATED  EXCHANGE  DEBENTURES  DUE  2027  FOR  ANY  AND ALL
OUTSTANDING 8.875% SENIOR SUBORDINATED DEBENTURES DUE 2027.

     The  Exchange  Offer  will  expire at 5:00  p.m.,  New York City  time,  on
February __, 1998, unless extended.
     The AES Corporation ("AES" or the "Company"), hereby offers, upon the terms
and subject to the conditions set forth in this Prospectus and the  accompanying
Letter of  Transmittal  (which  together  constitute the "Exchange  Offer"),  to
exchange $1,000 principal amount of 8.50% Senior Subordinated Exchange Notes due
2007 (the "New 8.50% Notes") of the Company for each $1,000  principal amount of
the issued and outstanding  8.50% Senior  Subordinated  Notes due 2007 (the "Old
8.50% Notes") of the Company and to exchange $1,000  principal  amount of 8.875%
Senior  Subordinated  Exchange Debentures due 2027 (the "New 8.875% Debentures",
and together with the New 8.50% Debentures,  the "New Notes") of the Company for
each  $1,000  principal  amount of the  issued  and  outstanding  8.875%  Senior
Subordinated  Debentures due 2027 (the "Old 8.875%  Debentures",  and,  together
with the Old 8.50% Notes,  the "Old  Notes") of the  Company.  As of the date of
this  Prospectus,  there were outstanding  $375,000,000  principal amount of Old
8.50% Notes and  $125,000,000  principal  amount of Old 8.875%  Debentures.  The
terms of the New 8.50% Notes are  identical in all material  respects to the Old
8.50%  Notes and the terms of the New 8.875%  Debentures  are  identical  in all
material  respects  to the Old 8.875%  Debentures,  in each case except that the
offer of the New Notes will have been  registered  under the  Securities Act and
therefore,  the New Notes will not be subject to certain transfer  restrictions,
registration  rights and related liquidated damage provisions  applicable to the
Old Notes.

     The Old 8.50%  Notes were issued at 99.800% of their  principal  amount and
the Old 8.875% Debentures were issued at 97.040% of their principal amount.  The
New Notes will bear interest  from October 29, 1997.  Holders of Old Notes whose
Old Notes are accepted  for exchange  will be deemed to have waived the right to
receive any payment in respect of interest on the Old Notes accrued from October
29, 1997 to the date of issuance of the New Notes.  Interest on the New Notes is
payable  semi-annually on May 1 and November 1, commencing May 1, 1998, accruing
from  October 29, 1997 at a rate of 8.50% per annum in the case of the New 8.50%
Notes  and  at a rate  of  8.875%  per  annum  in the  case  of the  New  8.875%
Debentures.

     The New 8.50% Notes and Old 8.50% Notes  (collectively,  the "8.50% Notes")
are  redeemable  at any time on or after  November  1,  2002 and the New  8.875%
Debentures and the Old 8.875% Debentures (collectively,  the "8.875% Debentures"
and,  together with the 8.50% Notes,  the "Notes") are redeemable at any time on
or after  November  1,  2004,  in each  case,  for cash at the option of The AES
Corporation  ("AES" or the  "Company"),  in whole or in part, at the  redemption
prices set forth herein, plus accrued interest.  In addition,  prior to November
1, 2000, in the event that the Company  consummates one or more offerings of its
Qualified  Capital Stock (as defined herein),  the Company may at its option use
all or a portion of the net cash  proceeds  from such  offerings to redeem up to
33% of the  original  aggregate  principal  amount of the 8.50%  Notes at a cash
redemption price equal to 108.500% of the principal amount thereof and up to 33%
of the original  aggregate  principal amount of the 8.875%  Debentures at a cash
redemption  price equal to 108.875% of the  principal  amount  thereof,  in each
case, plus accrued and unpaid interest thereon,  if any, to the redemption date;
provided that at least $100 million of the original  aggregate  principal amount
of the 8.50% Notes and $83.75 million of the original aggregate principal amount
of the 8.875% Debentures  remains  outstanding,  as the case may be, thereafter.
The Notes are  redeemable  at the option of the holder  upon a Change of Control
(as defined herein) at 101% of the principal  amount  thereof,  plus accrued and
unpaid interest thereon. The Notes are unsecured  obligations of the Company and
subordinated  to all existing and future  Senior Debt as defined  herein) of the
Company.  As of September  30, 1997, on a pro forma basis after giving effect to
the Adjustments (as defined herein),  the Company had approximately $207 million
in aggregate principal amount of Senior Debt and the subsidiaries of the Company
had  approximately  $4.0 billion in aggregate amount of liabilities to which the
Notes are effectively subordinated.

     The New Notes are  being  offered  hereunder  in order to  satisfy  certain
obligations  of the  Company  under the  Registration  Rights  Agreement,  dated
October  29,  1997,  among the Company and the other  signatories  thereto  (the
"Registration  Rights  Agreement").  Based  upon  interpretations  contained  in
letters  issued to third  parties by the staff of the  Securities  and  Exchange
Commission (the "Commission" or "SEC"),  the Company believes that the New Notes
issued  pursuant  to the  Exchange  Offer in  exchange  for the Old Notes may be
offered for resale,  resold and  otherwise  transferred  by each Holder  thereof
(other than a broker-dealer, as set forth below, and any such Holder which is an
"affiliate"  of the Company  within the meaning of Rule 405 under the Securities
Act of 1933, as amended,  (the  "Securities  Act")) without  compliance with the
registration and prospectus  delivery provisions of the Securities Act, provided
that  such New Notes  are  acquired  in the  ordinary  course  of such  Holder's
business and such Holder has no arrangement or understanding  with any person to
participate in the  distribution of such New Notes.  Eligible Holders wishing to
accept  the  Exchange  Offer  must  represent  to the  Company  in the Letter of
Transmittal  that  such  conditions  have been met and must  represent,  if such
Holder is not a  broker-dealer,  or is a broker-dealer  but will not receive New
Notes in for its own account in exchange for Old Notes, that neither such Holder
nor the person  receiving such New Notes, if other than a Holder,  is engaged in
or  intends  to  participate  in  the  distribution  of  such  New  Notes.  Each
broker-dealer  that  receives  New Notes  for its own  account  pursuant  to the
Exchange Offer must  represent that the Old Notes tendered in exchange  therefor
were  acquired  as  a  result  of  market-making  activities  or  other  trading
activities and must  acknowledge that it will deliver a prospectus in connection
with any resale of such New Notes.  The Letter of Transmittal  states that by so
acknowledging and by delivering a prospectus, a broker-dealer will not be deemed
to admit that it is an  "underwriter"  within the meaning of the Securities Act.
This Prospectus,  as it may be amended or supplemented from time to time, may be
used by a  broker-dealer  in  connection  with resales of New Notes  received in
exchange for Old Notes where such Old Notes were acquired by such  broker-dealer
as a result of market-making activities or other trading activities. The Company
has agreed that, for a period of 90 days after the  Expiration  Date (as defined
herein), it will make this Prospectus  available to any broker-dealer for use in
connection with any such resale. See "Plan of Distribution."

     The Company will not receive any  proceeds  from the  Exchange  Offer.  The
Company will pay all the expenses incident to the Exchange Offer. Tenders of Old
Notes  pursuant to the Exchange  Offer may be withdrawn at any time prior to the
Expiration Date. In the event the Company terminates the Exchange Offer and does
not accept for exchange any Old Notes, the Company will promptly return tendered
Old Notes to the Holders thereof.

     Prior to this  Exchange  Offer,  there  has been no public  market  for the
Notes.  The  Company  does not  currently  intend  to list the New  Notes on any
securities  exchange or to seek  approval for  quotation  through any  automated
quotation system. There can be no assurance that an active public market for the
New Notes will develop.

     SEE "RISK  FACTORS" FOR A DISCUSSION OF CERTAIN RISK FACTORS THAT SHOULD BE
CONSIDERED BY HOLDERS PRIOR TO TENDERING THEIR OLD NOTES IN AN EXCHANGE OFFER.

  THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
       EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
       SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMIS-
         SION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS.
            ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

registration  statement  relating  to these  securities  has been filed with the
Securities  and Exchange  Commission.  These  securities may not be sold nor may
offers to buy be accepted prior to the time the registration  statement  becomes

                               PROSPECTUS SUMMARY


     The  following  summary is qualified in its entirety by, and should be read
in connection  with, the more detailed  information and  consolidated  financial
statements and the notes thereto  included and incorporated by reference in this
Prospectus.  References  herein  to  "AES"  or the  "Company"  include  The  AES
Corporation  and its  subsidiaries  and affiliates  unless the context  requires
otherwise and references herein to "MW" are to megawatts.


                                  THE COMPANY

     AES is a  global  power  company  committed  to  supplying  electricity  to
customers  world-wide in a socially  responsible way. The Company was one of the
original  entrants  in the  independent  power  market  and  today is one of the
world's  largest  global  power  companies,  based on net  equity  ownership  of
generating  capacity (in  megawatts)  in operation  or under  construction.  AES
markets  power  principally  from  electricity  generating  facilities  that  it
develops, acquires, owns and operates.

     Over the last five years, the Company has experienced  significant  growth.
This growth has resulted  primarily from the development and construction of new
plants  ("greenfield  development")  and also from the  acquisition  of existing
generating  plants  and  distribution   companies,   through  competitively  bid
privatization   initiatives   outside  of  the  United   States  or   negotiated
acquisitions.  Since 1992, the Company's total generating  capacity in megawatts
has  grown  from  1,829 MW to 18,538 MW (an  increase  of 914%),  with the total
number of plants in operation  increasing  from eight to 74.  Additionally,  the
Company's  total revenues have increased at a compound annual growth rate of 20%
from  $401  million  in 1992 to $835  million  in 1996,  while  net  income  has
increased  at a  compound  annual  growth  rate of 22% from $56  million to $125
million and  Consolidated  EBITDA (as defined  herein)  has  increased  from $45
million to $189 million over the same period.

     AES  operates  and owns  (entirely or in part),  through  subsidiaries  and
affiliates,  power  plants in ten  countries  with a capacity  of  approximately
18,538 MW (including  4,000 MW  attributable  to Ekibastuz which currently has a
capacity  factor  of up to  approximately  20%).  AES  is  also  constructing  9
additional  power  plants in seven  countries  with a capacity of  approximately
4,921 MW.  The  Company's  total  ownership  in plants  in  operation  and under
construction aggregates  approximately 23,459 MW and its net equity ownership in
such plants is approximately  11,699 MW. In addition,  AES has numerous projects
in advanced stages of development, including seven projects with design capacity
of  approximately  3,398 MW that  have  executed  or been  awarded  power  sales
agreements. 

     The  Company  is also  engaged  (entirely  or in  part) in  electric  power
distribution   businesses  in  Latin  America  through  its   subsidiaries   and
affiliates.  These subsidiaries and affiliates serve approximately eight million
commercial,  industrial and  residential  customers using  approximately  63,000
gigawatt hours per year.

     As a result  of the  Company's  significant  growth in  recent  years,  the
Company's  operations have become more diverse with regard to both geography and
fuel  source  and it has  reduced  its  dependence  upon any  single  project or
customer.  During 1996, four of the Company's projects individually  contributed
more than 10% of the Company's  total  revenues;  Shady Point which  represented
approximately 20%, San Nicolas which represented approximately 16%, Thames which
represented  approximately 16% and Barbers Point which represented approximately
15%.

     The Company, a corporation organized under the laws of Delaware, was formed
in 1981.  The  principal  office of the  Company  is  located at 1001 North 19th
Street, Suite 2000, Arlington, Virginia 22209, and its telephone number is (703)
522-1315.

                                    OUTLOOK

     The  global  trend  of  electricity   market   restructuring   has  created
significant new business opportunities for companies like AES. Both domestic and
international  electricity  markets are being  restructured and there is a trend
away from government-owned  electricity systems toward deregulated,  competitive
market  structures.  Many countries have rewritten their laws and regulations to
allow  foreign  investment  and private  ownership  of  electricity  generation,
transmission or distribution  systems. Some countries have or are in the process
of  "privatizing"  their  electricity  systems  by  selling  all or part of such
systems to private  investors.  With 69 of its operating plants and distribution
companies  having been acquired or commenced  commercial  operations since 1992,
AES has  been an  active  participant  in both the  international  privatization
process and the development  process.  The Company is currently pursuing over 90
projects  including  acquisitions,  the  expansion  of  existing  plants and new
projects.

     AES  believes  that  there  is  significant  demand  for  both new and more
efficiently  operated  electric  generating  capacity in many regions around the
world.  In an effort to further grow and diversify  the  Company's  portfolio of
electric generating plants, AES is pursuing,  through its integrated  divisions,
additional greenfield  developments and acquisitions in many countries.  Several
of these  acquisitions,  if  consummated,  would  require  the Company to obtain
substantial additional financing, in the form of both debt and equity financing,
in the short term.


                                    STRATEGY

     The Company's  strategy in helping meet the world's need for electricity is
to participate in competitive power markets as they develop either by greenfield
development or by acquiring and operating  existing  facilities or  distribution
systems in these markets.  The Company generally  operates  electric  generating
facilities  that utilize  natural gas, coal,  oil, hydro power,  or combinations
thereof.   In  addition,   the  Company   participates  in  the  electric  power
distribution and retail supply businesses in certain limited instances, and will
continue to review opportunities in such markets in the future.

     Other elements of the Company's strategy include:

     o    Supplying energy to customers at the lowest cost possible, taking into
          account factors such as reliability and environmental performance;

     o    Constructing  or  acquiring   projects  of  a  relatively  large  size
          (generally larger than 100 MW);

     o    When  available,  entering  into power sales  contracts  with electric
          utilities or other customers with significant credit strength; and

     o    Participating in electric power distribution and retail supply markets
          that grant concessions with long-term pricing arrangements.

     The Company also strives for  operating  excellence as a key element of its
strategy, which it believes it accomplishes by minimizing  organizational layers
and maximizing company-wide participation in decision-making.  AES has attempted
to create an  operating  environment  that  results in safe,  clean and reliable
electricity generation. Because of this emphasis, the Company prefers to operate
all facilities which it develops or acquires; however, there can be no assurance
that the Company will have operating control of all of its facilities.

     Where  possible,  AES attempts to sell  electricity  under  long-term power
sales  contracts.  The Company  attempts,  whenever  possible,  to structure the
revenue  provisions of such power sales  contracts such that changes in the cost
components of a facility  (primarily fuel costs)  correspond,  as effectively as
possible, to changes in the revenue components of the contract. The Company also
attempts to provide fuel for its  operating  plants  generally  under  long-term
supply agreements,  either through  contractual  arrangements with third parties
or, in some instances, through acquisition of a dependable source of fuel. 


                                       6
<PAGE>


     As electricity  markets become more  competitive,  it may be more difficult
for AES (and other power  generation  companies) to obtain long-term power sales
contracts.  In markets where  long-term  contracts are not  available,  AES will
pursue  methods to hedge  costs and  revenues  to provide as much  assurance  as
possible of a project's profitability.  In these situations, AES might choose to
purchase a project with a partial hedge or with no hedge, with the strategy that
its  diverse  portfolio  of  projects  provides  some  hedge  to  the  increased
volatility of the project's earnings and cash flow. Additionally, AES may choose
not to participate in these markets.

     The Company  attempts to finance each domestic and foreign plant  primarily
under loan  agreements  and  related  documents  which,  except as noted  below,
require the loans to be repaid  solely from the  project's  revenues and provide
that the repayment of the loans (and interest  thereon) is secured solely by the
capital  stock,  physical  assets,  contracts  and/or  cash  flow of that  plant
subsidiary  or  affiliate.  This type of financing  is generally  referred to as
"project financing." The lenders under these project financing structures cannot
look to AES or its other projects for repayment,  unless such entity  explicitly
agrees to undertake  liability.  AES has explicitly  agreed to undertake certain
limited  obligations  and contingent  liabilities,  most of which by their terms
will only be  effective  or will be  terminated  upon the  occurrence  of future
events. In certain  circumstances,  the Company may incur  indebtedness which is
recourse to the Company or to more than one project.



                              RECENT DEVELOPMENTS


Recent Acquisitions

     On January 21, 1998, the Company announced that it won a bid to acquire for
$109 million the  outstanding  shares  (79.78%) of Compania de Luz  Electrica de
Santa Ana (CLESA),  an  electrical  distribution  company in El Salvador.  These
shares will be purchased from Comision  Ejecutiva  Hidroelectrica  del Rio Lempa
(CEL), a government-owned utility company. Energia Global International, Ltd., a
Bermuda company,  with activities in Central America,  may purchase up to 20% of
CLESA from AES.

     CLESA serves  188,000  customers and borders  Guatemala and Honduras to the
north, with access to the Pacific Ocean. Three other  distribution  companies in
El Salvador were sold in yesterday's auction to two other private companies.
Closing is expected to occur in mid-February 1998.

     In November 1997, the Company  announced that it won a bid to acquire three
natural gas-fired,  electric generating stations from Southern California Edison
for  approximately  $781  million.  The  facilities  were  auctioned  as part of
Edison's divestiture of all of its gas-fired generating  facilities prior to the
restructuring of California's electricity industry.

     The three  plants,  all  located  on the  southern  California  coast,  are
Alamitos (2083 MW),  Redondo Beach (1310 MW) and Huntington Beach (563 MW). Each
of the plants has been designated a "must-run  facility"  because station output
is critical to maintaining  the  reliability  of electric  supply in the region.
Consequently,  they  initially  will operate in part under  agreements  with the
Independent System Operator being established through electricity restructuring.
Pursuant to California's electricity restructuring law, Edison will remain under
contract to operate and maintain the facilities for two years.

     Completion  of the  acquisition  is  subject  to a  number  of  conditions,
including the receipt of California  Public  Utilities  Commission  approval and
successful implementation of the new California electric spot market, called the
Power Exchange.

     On October 21, 1997, a subsidiary of AES was the winning  bidder to acquire
approximately 90% of the common shares of Companhia Centro-Oeste de Distribuicao
de Energia Eletrica ("CCODEE"), the distribution company serving the central and
western  sections  of the  State of Rio  Grande  do Sul in  Brazil,  for a total
purchase price of approximately $1.37 billion. The acqui- 


                                       7
<PAGE>


sition  closed on October  27,  1997,  at which time the  Company  financed  the
payment of the purchase price with the proceeds of (i) $220 million of revolving
credit  borrowings  under  its  $425  million  revolving  credit  facility  (the
"Revolver")  (the commitments  under which had been  temporarily  increased from
$425  million to $600  million),  (ii) $550  million of short term loans under a
bridge loan  facility  (the "CEEE Bridge  Loan")  provided by affiliates of J.P.
Morgan Securities,  Inc., Donaldson,  Lufkin & Jenrette Securities  Corporation,
Salomon  Brothers  Inc and  Unterberg  Harris  (each  of  which  was an  Initial
Purchaser in one or both of the Initial  Offerings (as defined below)) and (iii)
$600 million of non-recourse financing under a $680 million facility provided by
BankBoston  and ANZ  Investment  Bank as  co-arrangers  (the "CEEE  Non-recourse
Financing").  AES purchased the shares of CCODEE from the State of Rio Grande do
Sul in a  partial  privatization  of  Companhia  Estadual  de  Energia  Eletrica
("CEEE"),  the  integrated  utility of Rio Grande do Sul.  All of the  remaining
shares of CCODEE may be  purchased by its  employees.  CCODEE  currently  serves
approximately  800,000 customers or approximately 31.3% of the population of the
State of Rio  Grande  do Sul on sales of 5,772  gigawatt  hours.  The  foregoing
transaction and the financing described therein and below are referred to herein
as the "CEEE Acquisition". The Borrowings under the Revolver and the CEEE Bridge
Loan were refinanced with the proceeds of the Initial Offerings.
See "Use of Proceeds".

     Also in October  1997, a joint venture named Tau Power that is 85% owned by
AES and 15% owned by  Israel-based  Suntree Power  completed the acquisition and
takeover of two hydro-electric stations ("GES") and four combined heat and power
stations  ("TETS")  in the  province  of East  Kazakhstan.  The  total  electric
capacity of the stations  included in the agreement is 1,384 MW, with additional
thermal capacity of over 1,000 MW electric  equivalent.  The transaction expands
AES's current global portfolio of electric generating facilities,  which already
includes the 4,000 MW  coal-fired  Ekibastuz  power station in  Kazakhstan.  The
power stations included in the agreement signed are: the 332 MW  Ust-Kamenogorsk
GES,  the 702 MW  Shulbinsk  GES,  the 240 MW  Ust-Kamenogorsk  TETS,  the 50 MW
Leninogorsk  TETS,  the 50 MW Sogrinsk  TETS and the 10 MW  Semipalatinsk  TETS.
Included in the  transaction,  AES obtained  ownership and control of the retail
sales department of the former utility and will assume the existing power supply
contracts  with the 50  largest  customers  in East  Kazakhstan,  including  the
distribution  companies.  Tau Power paid $20.7 million for the concession on the
GES, with an additional  payment of $2.5 million for the shares of the TETS. The
Company  will also repay back wages of  approximately  $4 million to the workers
during the first year of  operation  and provide for working  capital to finance
the delivery of much needed coal prior to winter and complete winter preparation
plans. 

     In June 1997,  AES together with The Southern  Company and The  Opportunity
Fund,  a  Brazilian  investment  fund,  (collectively,  the  "AES  Consortium"),
acquired 14.41% of Companhia Energ-tica de Minas Gerais ("CEMIG"), an integrated
electric  utility  serving  the  State of Minas  Gerais in  Brazil,  for a total
purchase price of  approximately  $1.056 billion,  $654 million of the financing
for which was in the form of non-recourse  financing  provided by Banco Nacional
de Desenvolvimento  Economico e Social ("BNDES").  AES's portion of the purchase
price was approximately $364 million after  consideration of the BNDES facility.
The shares of CEMIG,  which represent  approximately 33% of the voting interest,
have been purchased from the State of Minas Gerais in a partial privatization of
CEMIG.  Initially,  AES and The Opportunity Fund had a 90.6% and a 9.4% economic
interest in the AES Consortium, respectively. Subsequently, The Southern Company
exercised  its option to purchase 25% interest in the AES  Consortium  from AES.
Pursuant to a shareholders agreement between the AES Consortium and the State of
Minas Gerais, AES will have significant operating influence, including the right
to appoint  the chief  operating  officer  of CEMIG,  and will  otherwise  share
control of CEMIG with the State of Minas Gerais.  CEMIG owns approximately 5,000
MW of  generating  plants  and serves  approximately  4 million  customers.  The
foregoing transaction and the financing therefor described below are referred to
herein as the "CEMIG Acquisition".


                                       8

     In June 1997, AES completed its acquisition of the international  assets of
Destec  Energy,  Inc.  ("Destec"),  a large  independent  energy  producer  with
headquarters in Houston,  Texas, at a total price to AES of  approximately  $439
million.  Destec's  international  assets  acquired  by  AES  include  ownership
interests in the  following  five  electric  generating  plants (with  ownership
percentages  in  parentheses):  (i) a 110 MW gas-fired  combined  cycle plant in
Kingston,  Canada  (50%);  (ii) a 405  MW  gas-fired  combined  cycle  plant  in
Terneuzen,  Netherlands  (50%);  (iii) a 140 MW gas-fired  simple cycle plant in
Cornwall,  England (100%);  (iv) a 235 MW oil-fired  simple cycle plant in Santo
Domingo,  Dominican  Republic  (99%);  and  (v)  a  1,600  MW  coal-fired  plant
("Hazelwood") in Victoria,  Australia (20%). Each of such plants is currently in
operation,  except for the plant in Terneuzen which is under  construction.  The
acquisition  by AES of  Destec's  international  assets also  includes  Destec's
non-U.S.  developmental stage power projects,  including projects in Taiwan, the
Philippines,   Australia  and  Argentina.  The  foregoing  transaction  and  the
financing  therefor  described  below are  referred  to  herein  as the  "Destec
Acquisition".

     In May  1997,  a  subsidiary  of AES,  and its  partner,  Community  Energy
Alternatives  ("CEA"),  acquired an aggregate  of 90% (AES  acquired 60% and CEA
acquired  30%) of two  distribution  companies  of Empresa  Social de Energia de
Buenos Aires S.A.  ("ESEBA")  serving certain portions of the Province of Buenos
Aires,  Argentina for an aggregate purchase price of $565 million. AES's portion
of the purchase price after consideration of non-recourse debt was $244 million.
The  remaining  10% is  owned  by the  employees  of each  of the  two  acquired
companies.  The  foregoing  transaction  is  referred  to herein  as the  "ESEBA
Acquisition".

     AES funded its  acquisition  of Destec  through cash on hand and borrowings
under the  Revolver.  The net  proceeds of  approximately  $387 million from the
Company's  issuance and sale of its common stock,  par value $.01 per share (the
"AES Common Stock"), and $2.6875 Term Convertible Securities,  Series A ("Series
A TECONS") in March 1997 was  temporarily  applied to repay amounts  outstanding
under the Revolver.  AES financed its  acquisitions  of CEMIG and ESEBA through:
(i) $450 million in non-recourse  bridge financing,  comprised of a $250 million
bridge  loan  (the  "CEMIG  Bridge")  to  AES  CEMIG  Funding   Corporation,   a
wholly-owned  subsidiary  of AES,  and a $200  million  bridge  loan (the "ESEBA
Bridge") to AESEBA Funding Corporation, a wholly-owned subsidiary of AES; (ii) a
$200  million  subordinated  bridge loan to AES (the "AES Bridge  Loan");  (iii)
non-recourse  project debt; (iv) borrowings under AES's Revolver and (v) cash on
hand.

     AES  intends  to repay the ESEBA  Bridge  and the  CEMIG  Bridge  through a
combination of proceeds from: (i) the sale of AES's interest in Hazelwood;  (ii)
additional borrowings at one or more AES projects; (iii) the replacement of cash
reserves with letters of credit at certain AES projects;  (iv) the proceeds from
the  exercise of the Southern  Company's  option to purchase 25% interest in the
AES  Consortium  from AES or (v)  borrowings  under  the  Revolver.  None of the
foregoing  sources of funds is  committed  except for the  exercise  of Southern
Company's option.  Accordingly,  there can be no assurances that such sources or
any other sources will be available to repay the ESEBA Bridge and CEMIG Bridge.

     The CEMIG Bridge and ESEBA Bridge  mature in August 1998 or, in the case of
the ESEBA Bridge,  earlier if AES sells its interest in Hazelwood.  The interest
rates on both the CEMIG Bridge and the ESEBA Bridge will initially be LIBOR plus
2.5% and will  increase by 1.0% each month  beginning  February  1, 1998.  These
loans are secured by a pledge of 34.6 million  shares of AES Common Stock issued
to a subsidiary of AES.

     These projects are subject to a number of risks  including those related to
financing,  construction and contract compliance,  and there can be no assurance
that they will be completed successfully.

Other Events

     In September 1997, AES began construction on the AES Parana project, an 830
MW  gas-fired,  combined  cycle power  plant.  AES Parana will be located in San
Nicolas, Argentina, adjacent to Central Termica San Nicolas, in which AES owns a
controlling interest. AES Parana is in the 


                                       9
<PAGE>


final stages of arranging for project financing for the facility. AES Parana has
entered into a lump sum, turnkey construction contract with Nichimen Corporation
and  Mitsubishi  Heavy  Industries  for the plant. A portion of the fuel will be
supplied  by Total  Corporation  under a long term,  risk  management  contract.
Project output will be sold into the Argentine  electric  market.  Total capital
cost is  estimated  at $440  million,  and the  project is  expected to commence
commercial operation in 2000.

     Also in September,  AES's 100% owned  subsidiary,  AES Mt.  Stuart,  raised
A$103.50  million   (approximately  US$75.5  million)  of  non-recourse  project
financing for its 288 MW kerosene-fired  simple cycle power plant in Townsville,
Queensland,  Australia.  The project debt facility was solely  under-written  by
Societe  Generale  Australia  Ltd.  and is  comprised  of a 10-year term loan, a
letter of credit  facility and a  short-term  revolving  cash advance  facility.
Low-cost   peaking  power  from  the  plant  will  be  sold  to  the  Queensland
Transitional Power Trading Corporation under a 10-year power purchase agreement.
A turnkey construction agreement has been signed with Nichimen Corporation,  and
the  major   equipment  will  be  supplied  by  Mitsubishi   Heavy   Industries.
Construction  of the plant will start  during the fourth  quarter of 1997 and is
scheduled to be completed on January 1, 1999.

     In July 1997, the Company  announced a two for one stock split, in the form
of a stock dividend, for holders of record on July 28, 1997 of its Common Stock,
par value $.01 per share, which was paid on August 28, 1997.

     In the same month, the Company issued  approximately $325 million of senior
subordinated  notes due 2007 with an 83/8%  interest rate per annum in a private
placement.  The Company used the net proceeds of  approximately  $315 million to
repay amounts outstanding under the AES Bridge Loan, to redeem the Company's $75
million 93/4% senior subordinated notes due 2000 and to repay pro rata a portion
of the amounts  outstanding  under the ESEBA  Bridge and the CEMIG  Bridge.  The
ESEBA Bridge and the CEMIG Bridge have been  refinanced  and are currently  $180
million and $106 million, respectively.

     Also in July, the Company sold 4.5 million shares of its common stock (on a
pre-split basis) for gross proceeds of approximately  $359 million or $79.75 per
share. The Company used the net proceeds of approximately  $350 million to repay
pro rata a portion of the  amounts  outstanding  under the ESEBA  Bridge and the
CEMIG Bridge.

     On  January  9, 1998,  the  Southern  Company  exercised  their  option for
approximately  $114 million  which was used  entirely to partially  pay down the
CEMIG Bridge to $106 million.

     Unless otherwise indicated, all share numbers and per share amounts in this
Prospectus have been restated to reflect the stock split.

                       CONSEQUENCE OF EXCHANGING OLD NOTES
                         PURSUANT TO THE EXCHANGE OFFER

     Based upon interpretations  contained in letters issued to third parties by
the staff of the SEC, the Company  believes that,  generally,  any Holder of Old
Notes (other than a broker-dealer,  as set forth below, and any Holder who is an
"affiliate"  of the Company  within the meaning of Rule 405 under the Securities
Act) who  exchanges its Old Notes for New Notes  pursuant to the Exchange  Offer
may  offer  such New Notes for  resale,  resell  such New  Notes,  or  otherwise
transfer such New Notes without  compliance with the registration and prospectus
delivery  provisions of the Securities Act, provided such New Notes are acquired
in  the  ordinary  course  of the  Holder's  business  and  such  Holder  has no
arrangement or understanding with any person to participate in a distribution of
such New Notes.  Eligible  Holders  wishing to accept  the  Exchange  Offer must
represent to the Company in the Letter of Transmittal  that such conditions have
been met and must  represent,  if such  Holder is not a  broker-dealer,  or is a
broker-dealer but will not receive New Notes for its own account in exchange for
Old Notes,  that neither such Holder nor the person receiving such New Notes, if
other  than  the  Holder,  is  engaged  in or  intends  to  participate  in  the
distribution of such New Notes. Each  broker-dealer  that receives New Notes for
its own  account in  exchange  for Old Notes must  represent  that the Old Notes
tendered  in  exchange  therefor  were  acquired  as a result  of  market-making
activities or other trading activities and must acknowledge that it will deliver
a  prospectus  in  connection  with any resale of such New  Notes.  See "Plan of
Distribution".  To comply with the securities laws of certain jurisdictions,  it
may be necessary to qualify for sale or register the New Notes prior to offering
or selling  such New Notes.  The Company does not  currently  intend to take any
action  to   register   or  qualify  the  New  Notes  for  resale  in  any  such
jurisdictions. If a Holder of Old Notes does not exchange such Old Notes for New
Notes pursuant to the Exchange Offer, such Old Notes will continue to be subject
to the restrictions on transfer contained in the legend thereon. In general, the
Old Notes may not be offered or sold,  unless  registered  under the  Securities
Act,  except  pursuant to an exemption from, or in a transaction not subject to,
the Securities Act and applicable  state securities laws. Any holder who tenders
in the Exchange Offer with the intention to  participate,  or for the purpose of
participating,  in a distribution of New Notes could not rely on the position of
the staff of the SEC enunciated in Exxon Capital Holdings Corporation (available
May 13, 1988) or  similar-no-action  letters and, in the absence of an exemption
therefrom,   must  comply  with  the   registration   and  prospectus   delivery
requirements  in such  instance  may result in such holder  incurring  liability
under the Securities Act for which the holder is not indemnified by the Company.
See "The Exchange Offer-Consequences of Failure to Exchange" and "Description of
Notes-Registration Rights."


                      SUMMARY DESCRIPTION OF THE NEW NOTES

     The terms of the New 8.50% Notes and the Old 8.50% Notes are  identical  in
all material  respects,  and the terms of the New 8.875%  Debentures and the Old
8.875%  Debentures are identical in all material  respects,  in each case except
that the offer of the New Notes will have been  registered  under the Securities
Act and,  therefore,  the New Notes  will not be  subject  to  certain  transfer
restrictions,  registration rights and related provisions  applicable to the Old
Notes.

NOTES OFFERED............   Up to $375  million  aggregate  principal  amount of
                            8.50% Senior  Subordinated  Exchange  Notes due 2007
                            and up to $125 million aggregate principal amount of
                            8.875% Senior  Subordinated  Exchange Debentures due
                            2027.

MATURITY DATE............   The 8.50%  Notes will mature on November 1, 2007 and
                            the 8.875%  Debentures  will  mature on  November 1,
                            2027.

INTEREST RATE............   The  8.50%  Notes  will bear  interest  at 8.50% per
                            annum and the 8.875%  Debentures  will bear interest
                            at 8.875% per annum.

                            The New Notes will bear  interest  from  October 29,
                            1997.  Holders  of Old  Notes  whose  Old  Notes are
                            accepted for exchange  will be deemed to have waived
                            the right to  receive  any  payment  in  respect  of
                            interest on such Old Notes  accrued from October 29,
                            1997  to  date of the  issuance  of the  New  Notes.
                            Consequently,  holders who exchange  their Old Notes
                            for New Notes will receive the same interest payment
                            on May 1, 1998 (the first interest payment date with
                            respect  to the Old  Notes and the New  Notes)  that
                            they would have  received  had they not accepted the
                            Exchange Offer.

INTEREST PAYMENT DATES...   May 1 and November 1, commencing May 1, 1998.

                            November 1, 2004. On and after that date, the 8.875%
                            Debentures  may be redeemed at any time, in whole or
                            in part,  on not less than 30 nor more than 60 days'

                            In addition, prior to November 1, 2000, in the event
                            that the Company  consummates  one or more offerings
                            of its Qualified  Capital Stock,  the Company may at
                            its  option  use all or a  portion  of the net  cash
                            proceeds from such  offerings to redeem up to 33% of
                            the original aggregate principal amount of the 8.50%
                            Notes at a cash  redemption  price equal to 108.500%
                            of the principal amount thereof and up to 33% of the
                            original  aggregate  principal  amount of the 8.875%
                            Debentures  at a  cash  redemption  price  equal  to
                            108.875% of the principal  amount  thereof,  in each
                            case, plus accrued and unpaid interest  thereon,  if
                            any, to the redemption date;  provided that at least
                            $100  million of the  original  aggregate  principal
                            amount of the 8.50% Notes and $83.75  million of the
                            original  aggregate  principal  amount of the 8.875%
                            Debentures,  as the case may be, remains outstanding
                            thereafter.

MANDATORY SINKING FUND PAY-
  MENTS..................   The 8.50% Notes are not subject to a  sinking  fund.

                            The  8.875%  Debentures  are  subject  to  mandatory
                            redemption on a pro rata basis through  operation of
                            a mandatory sinking fund on November 1 of each year,
                            commencing  on  November 1, 2008,  to and  including
                            November  1, 2026,  according  to the  sinking  fund
                            payments   set  forth   herein.   The  sinking  fund
                            redemption  price is 100% of the principal amount of
                            the 8.875% Debentures being redeemed,  together with
                            interest accrued to the date fixed for redemption.

RANKING..................   The Notes will be general  unsecured  obligations of
                            the  Company  and will be  subordinated  in right of
                            payment to all  Senior  Debt of the  Company.  As of
                            September  30,  1997,  on a pro  forma  basis  after
                            giving  effect to the  Adjustments,  the Company had
                            approximately $207 million in aggregate principal



                                       13
<PAGE>


                            amount of Senior Debt.  In addition,  the  Company's
                            subsidiaries  had  approximately   $4.0  billion  in
                            aggregate  amount of  liabilities to which the Notes
                            are effectively subordinated.

CHANGE OF CONTROL OFFER..   Upon a Change of  Control,  each Holder of the Notes
                            shall have, subject to certain conditions, the right
                            to require that the Company repurchase such Holder's
                            Notes at 101% of the principal amount thereof,  plus
                            accrued and unpaid  interest to the date of purchase
                            in accordance  with the  procedures set forth in the
                            Indenture  (as defined  herein) for the Notes.  If a
                            Change  of   Control   occurs,   the   subordination
                            provisions  of the Notes  require  Senior Debt to be
                            repaid prior to the purchase of any tendered  Notes.
                            Due to the highly  leveraged  nature of the Company,
                            there  can be no  assurance  that,  upon a Change of
                            Control,  the  Company  will be  able  to  fund  the
                            purchase of the Notes.  See "Description of Notes --
                            Covenants  --  Repurchase  of Notes Upon a Change of
                            Control."

PRINCIPAL COVENANTS......   The  Indenture  for the Notes will  restrict,  among
                            other  things,  the  ability of the  Company and its
                            Restricted  Subsidiaries  (as defined herein) to (i)
                            incur  additional  indebtedness,  (ii) pay dividends
                            and make other  distributions,  (iii)  make  certain
                            investments,  (iv) engage in  unrelated  businesses,
                            (v) create  encumbrances to secure Debt that is pari
                            passu with or subordinated to the Notes, (vi) engage
                            in  certain  transactions  with  affiliates,   (vii)
                            dispose  of  certain   assets  or  (viii)  merge  or
                            consolidate  with or  into,  or  sell  or  otherwise
                            transfer their  properties and assets as an entirety
                            to, another  entity.  See  "Description  of Notes --
                            Covenants."


                                 RISK FACTORS

                                 RISK FACTORS

     In addition to the other matters  described in this Prospectus,  Holders of
Old Notes should carefully  consider the following risk factors before accepting
the Exchange Offer. 


CONSEQUENCES OF FAILURE TO EXCHANGE

     Holders  of Old  Notes  who do not  exchange  their Old Notes for New Notes
pursuant to the Exchange  Offer will continue to be subject to the  restrictions
on  transfer of such Old Notes as set forth in the legend  thereon.  In general,
the Old Notes may not be offered or sold, unless registered under the Securities
Act,  except  pursuant to an exemption  from, or in a transaction not subject to
the Securities Act and applicable  state  securities  laws. The Company does not
intend to register the Old Notes under the Securities Act. The Company  believes
that, based upon interpretations contained in letters issued to third parties by
the  staff of the SEC,  New  Notes  issued  pursuant  to the  Exchange  Offer in
exchange  for  Old  Notes  may  be  offered  for  resale,  resold  or  otherwise
transferred  by each Holder thereof  (other than a  broker-dealer,  as set forth
below,  and any such Holder which is an  "affiliate"  of the Company  within the
meaning  of Rule 405 under  the  Securities  Act)  without  compliance  with the
registration and prospectus  delivery  provisions of the Securities Act provided
that  such New Notes  are  acquired  in the  ordinary  course  of such  Holder's
business and such Holder has no arrangement or understanding  with any person to
participate in the  distribution of such New Notes.  Eligible Holders wishing to
accept  the  Exchange  Offer  must  represent  to the  Company  in the Letter of
Transmittal  that  such  conditions  have been met and must  represent,  if such
Holder is not a  broker-dealer,  or is a broker-dealer  but will not receive New
Notes for its own account in exchange  for Old Notes,  that  neither such Holder
nor the person receiving such New Notes, if other than the Holder, is engaged in
or  intends  to  participate  in  the  distribution  of  such  New  Notes.  Each
broker-dealer  that  receives  New Notes  for its own  account  pursuant  to the
Exchange Offer must  represent that the Old Notes tendered in exchange  therefor
were  acquired  as  a  result  of  market-making  activities  or  other  trading
activities and must  acknowledge that it will deliver a prospectus in connection
with any resale of such New Notes.  The Letter of Transmittal  states that by so
acknowledging and by delivering a prospectus, a broker-dealer will not be deemed
to admit that it is an  "underwriter"  within the meaning of the Securities Act.
This Prospectus,  as it may be amended or supplemented from time to time, may be
used by a broker-dealer  in connection with the resales of New Notes received in
exchange for Old Notes where such Old Notes were acquired by such  broker-dealer
as a result of market-making activities or other trading activities. The Company
has agreed that, for a period of 90 days after the  Expiration  Date (as defined
herein), it will make this Prospectus  available to any broker-dealer for use in
connection with any such resale. See "Plan of Distribution."  However, to comply
with the securities laws of certain jurisdictions,  if applicable, the New Notes
may not be offered or sold unless they have been  registered  or  qualified  for
sale in such  jurisdiction or an exemption from registration or qualification is
available and is complied  with.  The Company does not currently  intend to take
any  action  to  register  or  qualify  the New  Notes  for  resale  in any such
jurisdictions.  In  addition,  the tender of Old Notes  pursuant to the Exchange
Offer will reduce the principal amount of the Old Notes  outstanding,  which may
have an adverse effect upon, and increase the volatility of, the market price of
the Old Notes due to a reduction in liquidity.


EXCHANGE OFFER PROCEDURES

     To participate in the Exchange  Offer,  and avoid the  restrictions  on Old
Notes,  each Holder of Old Notes must  transmit a properly  completed  Letter of
Transmittal,   including  all  other  documents   required  by  such  Letter  of
Transmittal, to the Exchange Agent at one of the addresses set forth below under
"Exchange  Agent")  on or  prior to the  Expiration  Date  (or  comply  with the
guaranteed  delivery  procedures  described  below on or before  the  Expiration
Date). In addition,  (i) certificates for such Old Notes must be received by the
Exchange Agent along with the Letter of Transmittal,  (ii) a timely confirmation
of a book-entry  transfer (a "Book-Entry  Confirmation")  of such Old Notes,  if
such procedure is available, into the Exchange Agent's account at The Depository
Trust Company (the "Book-Entry Transfer Facility") pursuant to the procedure for
book-entry  transfer  described  below,  must be received by the Exchange  Agent
prior to the Expiration Date or (iii) the Holder must comply with the guaranteed
delivery procedures described below. See "The Exchange Offer."

LEVERAGE AND SUBORDINATION

     The  Company  and  its  subsidiaries  had  approximately  $3.9  billion  of
outstanding  indebtedness  at September  30, 1997.  As a result of the Company's
level of debt, the Company might be significantly limited in its ability to meet
its 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  September  30,  1997,  the  Company had a
consolidated ratio of total debt to total book capitalization (including current
debt) of approximately 70%.

     The Notes will be  subordinated  to all  existing  and future  Senior Debt,
including,  but not limited to, the amounts outstanding under the Company's $425
million  Revolver.  As of September  30, 1997, on a pro forma basis after giving
effect to the  Adjustments,  the  Company  had  approximately  $207  million  in
aggregate principal amount of Senior Debt.

     Upon  any  payment  or   distribution  of  assets  to  creditors  upon  any
liquidation, dissolution, winding up, receivership,  reorganization,  assignment
for the  benefit  of  creditors,  marshaling  of assets and  liabilities  or any
bankruptcy,  insolvency or similar  proceedings  of the Company,  the holders of
Senior Debt will first be entitled to receive payment in full of all amounts due
or to become due under all Senior  Debt  before the holders of the Notes will be
entitled to receive any payment in respect of the principal of, premium, if any,
or interest on such Notes. No payments on account of principal, premium, if any,
or interest in respect of the Notes may be made if there shall have occurred and
be continuing a default in any payment  under any Senior Debt or during  certain
periods when an event of default under  certain  Senior Debt permits the lenders
thereunder to accelerate  the maturity  thereof.  See  "Description  of Notes --
Subordination."

     The Notes will be effectively  subordinated to the  indebtedness  and other
obligations  (including  trade  payables)  of  the  Company's  subsidiaries.  At
September 30, 1997, on a pro forma basis after giving effect to the Adjustments,
the  indebtedness  and  obligations  of the  Company's  subsidiaries  would have
aggregated  approximately  $4.0  billion.  The  ability  of the  Company  to pay
principal of, premium,  if any, and interest on the Notes will be dependent upon
the receipt of funds from its subsidiaries by way of dividends,  fees, interest,
loans or otherwise.  Most of the Company's  subsidiaries with interests in power
generation  facilities  currently have in place, and the Indenture for the Notes
will, under certain  circumstances,  permit the Company's  subsidiaries to enter
into,  arrangements  that restrict  their ability to make  distributions  to the
Company by way of dividends,  fees, interest,  loans or otherwise. The Company's
subsidiaries  are separate and distinct  legal  entities and have no obligation,
contingent or otherwise, to pay any amounts due pursuant to the Notes 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 Notes. Any right
of the  Company  to  receive  any  assets  of any of its  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 of the Company (and the consequent
right of the holders of the Notes 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 and preferred stock issued by such  subsidiary).  The Company  currently
conducts substantially all of its operations through its subsidiaries.

DOING BUSINESS OUTSIDE THE UNITED STATES

     The  Company's  involvement  in the  development  of new  projects  and the
acquisition  of  existing  plants in  locations  outside  the  United  States is
increasing  and  most  of the  Company's  current  development  and  acquisition
activities are for projects and plants  outside the United States.  The Company,
through subsidiaries,  affiliates and joint ventures, has ownership interests in
76 power plants  outside the United  States in operation or under  construction.
Thirty-nine  of such power  plants are located in Brazil;  nine in the  People's
Republic of China;  seven in  Kazakhstan;  six in Argentina;  five in the United
Kingdom;  three in Hungary;  two in each of Australia and  Pakistan;  and one in
each of the Netherlands, Canada and the Dominican Republic.

     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 


                                       16
<PAGE>


restrictions,  currency inconvertibility,  political instability,  civil unrest,
and expropriation) and other credit quality, liquidity or structural 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 AES
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 higher  investments by the Company 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 the
Company,  its  subsidiaries  and  its  affiliates  are or in the  future  may be
developing,  constructing  or  operating  could make it more  difficult  for the
Company to enforce  its  respective  rights  under  agreements  relating to such
projects.  In addition,  the laws and regulations of certain countries may limit
the Company's  ability to hold a majority  interest in some of the projects that
it may develop or acquire.  International  projects owned by the Company may, in
certain cases, be expropriated by applicable governments.  Although AES may have
legal recourse in enforcing its rights under  agreements and recovering  damages
for breaches thereof,  there can be no assurance that any such legal proceedings
will be successful.

COMPETITION

     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 the Company.
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 the Company  sells or intends to sell
power. There can be no assurance that the foregoing competitive factors will not
have a material adverse effect on the Company.

DEVELOPMENT UNCERTAINTIES

     The  majority of the  projects  that AES develops are large and complex and
the completion of any such project is subject to substantial risks.  Development
can require the Company to expend significant sums for preliminary  engineering,
permitting,  legal and other expenses in preparation for competitive  bids which
the  Company  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
on terms satisfactory to the Company of 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 AES 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 its  projects.  There can be no  assurance  that  development  efforts on any
particular project, or the Company's efforts generally,  will be successful.  If
these development efforts are not successful,  the Company may abandon a project
under  development.  At the time of  abandonment,  the Company would expense all
capitalized  development costs incurred in connection  therewith and could incur
additional losses associated with any related contingent liabilities. The future
growth of the Company is  dependent,  in part,  upon the demand for  significant
amounts of additional  electrical  generating capacity and its ability to obtain
contracts to supply portions of this capacity. Any material unremedied delay in,
or unsatisfactory  completion of,  construction of the Company's projects could,
under certain circumstances,  have an adverse effect on the Company's ability to
meet its obligations, including the payment of principal of, premium, if any and
interest  on the  Notes.  The  Company  also is faced with  certain  development
uncertainties  arising out of doing business  outside of the United States.  See
"-- Doing Business Outside the United States."

RISKS ASSOCIATED WITH ACQUISITIONS

     The  Company  has  achieved a  significant  portion  of its growth  through
acquisitions  and  expects  that it will  continue  to grow,  in  part,  through
acquisitions.  During 1997 alone the Company  consummated the ESEBA Acquisition,
the Destec Acquisition,  the CEMIG Acquisition and the CEEE Acquisition in which
the Company  invested an aggregate  of  approximately  $1.9  billion  (excluding
non-recourse  debt).  Although each of the acquired businesses had a significant
operating history at the time of its acquisition by the Company, the Company has
a limited history of owning and operating 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 by the Company.  There can
be no assurances that the Company 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.

UNCERTAINTY OF ACCESS TO CAPITAL FOR FUTURE PROJECTS

     Each of AES's projects under development and those independent power supply
businesses it may seek to acquire may require  substantial  capital  investment.
Continued  access to capital  with  acceptable  terms is necessary to assure the
success of future  projects and  acquisitions.  AES has  substantially  utilized
project  financing  loans  to fund  the  capital  expenditures  associated  with
constructing and acquiring its electric power plants and related assets. Project
financing borrowings have been substantially  non-recourse to other subsidiaries
and affiliates and to AES 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.  The  Company  intends  to  continue  to seek,  where
possible,  such  non-recourse  project  financing in connection  with the assets
which the Company or its affiliates may develop,  construct or acquire. However,
depending on market  conditions  and the unique  characteristics  of  individual
projects,  such  financing  may not be  available or the  Company's  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,  the Company, in such locations,  has and will
continue to seek  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,  AES may  determine  that  sufficient  financing  will
ultimately not be available to fund the related project.

     In addition to the project  financing  loans, if available,  AES provides 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 the  short-term  credit  facilities  and  issuances  of senior
subordinated notes, convertible debentures and common stock of the Company.

     The Company's  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 in the Company,
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,  AES 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 AES on its
currently operating facilities or facilities under construction, such a decision
would affect the future growth of AES. 


DEPENDENCE ON UTILITY CUSTOMERS AND CERTAIN PROJECTS

     The  nature of most of AES's  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.
During  1996,  five  customers,   including  CL&P,  a  subsidiary  of  Northeast
Utilities, ac- 


                                       18
<PAGE>


counted for 73% of the  Company's  consolidated  total  revenues.  The prolonged
failure of any one utility customer to fulfill its contractual obligations could
have a substantial negative impact on AES's primary source of revenues.  AES has
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.

     Four of the Company's plants collectively represented  approximately 39% of
AES's consolidated total assets at December 31, 1996 and generated approximately
67% of AES's consolidated total revenues for the year ended December 31, 1996.

     Sales to Connecticut Light & Power Company ("CL&P")  represented 16% of the
Company's total revenues in 1996. Moody's Investor Service Inc.  ("Moody's") and
Standard & Poor's  Corporation  ("S&P") have recently  downgraded  CL&P's senior
secured long-term debt from Baa3/BBB- to Ba2/BB and S&P has placed CL&P on watch
for possible  downgrade.  As a result of regulatory action by the Public Service
Commission  of New  Hampshire,  Moody's and S&P recently  downgraded  the senior
unsecured debt of Northeast Utilities,  the parent of CL&P, from Ba2/BB to B1/B+
and S&P has placed Northeast Utilities on watch for possible downgrade.


REGULATORY UNCERTAINTY

     AES's  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 of 1935, 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.  AES is not and will not be
subject to regulation  as a holding  company under PUHCA as long as the domestic
power plants it owns 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.  The Company believes that, upon the occurrence of an event that would
threaten the QF status of one of its domestic plants,  it would be able to react
in a manner that would  avoid the loss of QF status  (such as by  replacing  the
steam customer).  In the event the Company were unable to avoid the loss of such
status for one of its plants,  to avoid public utility  holding  company status,
AES 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 the
consolidated  income tax group or the consolidated  financial  statements of the
Company, or an increase or decrease in the results of operations of the Company.

     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  independents  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 and/or
PUHCA may or may not be part of  comprehensive  legislation to  restructure  the
electric  utility  industry,  allow  retail  competition,  and  deregulate  most
electric rates. The effect of any such repeal cannot be predicted,  although any
such repeal could have a material adverse effect on the Company.

ELECTRIC UTILITY INDUSTRY RESTRUCTURING PROPOSALS

     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 of any such  restructuring on the Company
cannot be  predicted,  although  any such  restructuring  could  have a material
adverse effect on the Company.


LITIGATION AND REGULATORY PROCEEDINGS

     From time to time, the Company and its affiliates are parties to litigation
and regulatory  proceedings.  Investors  should review the  descriptions of such
matters contained in the Company's  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 the Company.


BUSINESS SUBJECT TO STRINGENT ENVIRONMENTAL REGULATIONS

     AES's  activities  are subject to  stringent  environmental  regulation  by
federal,  state, local and foreign  governmental  authorities.  For example, the
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 AES's power plants.  There can
be no  assurance  that AES would be able to recover all or any  increased  costs
from its  customers  or that its  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. The Company has 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 the Company's  financial
condition or results of operations.


CONTROL BY EXISTING STOCKHOLDERS

     As of September 30, 1997,  AES's two founders,  Roger W. Sant and Dennis W.
Bakke, and their immediate  families together owned  beneficially  approximately
22.1% of the  outstanding  AES  Common  Stock.  As a result  of their  ownership
interests,  Messrs.  Sant and Bakke may be able to  significantly  influence  or
exert  control over the affairs of AES,  including the election of the Company's
directors.  As of September  30, 1997,  all of AES's  officers and directors and
their immediate families together owned beneficially  approximately 29.2% of the
outstanding  AES Common Stock.  To the extent that they decide to vote together,
these  stockholders  would be able to  significantly  influence  or control  the
election of AES's  directors,  the management and policies of AES and any action
requiring  stockholder approval,  including significant corporate  transactions.

ADHERENCE TO AES'S PRINCIPLES -- POSSIBLE IMPACT ON RESULTS OF OPERATIONS

     A  core  part  of  AES's  corporate  culture  is a  commitment  to  "shared
principles":  to act with integrity,  to be fair, to have fun and to be socially
responsible.  The Company seeks 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 the Company  perceives a conflict between these principles
and  profits,  the Company will try to adhere to its  principles  -- even though
doing so might  result in  diminished  or foregone  opportunities  or  financial
benefits.


LACK OF PUBLIC MARKET

     The New Notes are being  offered to the  Holders of the Old Notes.  The Old
Notes  were  issued on October  29,  1997 to a limited  number of  institutional
investors.  The New Notes are new  securities  for which there  currently  is no
market.  The  Company  does not intend to apply for  listing of the Notes on any
securities  exchange  or for  quotation  through  the  National  Association  of
Securities Dealers Automated Quotation System. There can be no assurance that an
active  trading  market  for the New Notes  will  develop.  If a trading  market
develops for the New Notes, future trading prices of such securities will depend
on many factors,  including  prevailing interest rates, the Company's results of
operations and financial condition and the market for similar securities.


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 AES's creditors in a lawsuit to subordinate or avoid the Notes
in favor  of  other  existing  or  future  creditors  of AES.  Under  applicable
provisions  of the  U.S.  Bankruptcy  code or  comparable  provisions  of  state
fraudulent  transfer or  conveyance  laws, if AES at the time of issuance of the
Notes, (i) incurred such  indebtedness  with intent to hinder,  delay or defraud
any present or future creditor of AES or  contemplated  insolvency with a design
to prefer one or more  creditors to the  exclusion in whole or in part of others
or (ii) received less than reasonably equivalent value or fair consideration for
issuing  the Notes and AES (a) was  insolvent,  (b) was  rendered  insolvent  by
reason of the  issuance  of the  Notes,  (c) was  engaged  or about to engage in
business  or a  transaction  for which the  remaining  assets of AES  constitute
unreasonably small capital to carry on its business or (d) intended to incur, or
believed that it would incur, debts beyond its ability to pay such debts as they
mature,  then,  in each case, a court of competent  jurisdiction  could void, in
whole or in part, the Notes.  Among other things, a legal challenge of the Notes
on fraudulent  conveyance grounds may focus on the benefits, if any, realized by
AES as a result of the issuance by AES of the Notes.

     The measure of insolvency for purposes of the foregoing will vary depending
upon the law applied in such case.  Generally,  however, AES would be considered
insolvent  if the  sum of its  debts,  including  contingent  liabilities,  were
greater  than all of its assets at fair  valuation or if the present fair market
value of its assets  were less than the amount that would be required to pay the
probable liability on its 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 Notes.

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

(1) For purposes of this ratio,  earnings  include income before taxes and fixed
    charges  excluding  capitalized  interest.  Fixed charges include  interest,
    whether  capitalized or expensed,  and  amortization  of deferred  financing
    costs, whether capitalized or expensed.

(2) Parent debt represents  obligations of the Company,  as parent.  It does not
    include non-recourse obligations of the Company's subsidiaries.

(3) The other data  presented  for  "Consolidated  EBITDA," "Consolidated  Fixed
    Charges" and "Fixed  Charge  Ratio" is  calculated  in  accordance  with the
    respective  definitions  of such terms in the Indenture and set forth herein
    under  "Description  of Notes -- Certain  Definitions."  As of September 30,
    1997,  on a  pro  forma  basis  after  giving  effect  to  the  Adjustments,
    Consolidated EBITDA, Consolidated Fixed Charges, and Fixed Charge Ratio were
    $246 million, $99 million, and 2.5x, respectively.

(4) Consolidated  EBITDA  is a concept  defined  in the  Indenture  and is not a
    substitute for cash flows from operating  activities as defined by generally
    accepted accounting principles.

</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 the Company  believes to be  representative  of an interest
factor. A statement setting forth the computation of the above ratios is on file
as an exhibit to the Registration Statement of which this Prospectus is a part.

     During the period from January 1, 1992 until  September 30, 1997, no shares
of  Preferred  Stock were  issued or  outstanding,  and during  that  period the
Company did not pay any Preferred Stock dividends.


                                 USE OF PROCEEDS

     The Company will not receive any cash proceeds from the issuance of the New
Notes  offered  hereby.  The net proceeds  from the offering of the Old Notes of
approximately  $486 million were used,  together with approximately $291 million
from the TECONS offering to repay approximately $770 million of the indebtedness
incurred in connection with the CEEE  Acquisition  (consisting of  approximately
$220 million under the Revolver and $550 million under the CEEE Bridge Loan) and
for general corporate purposes, including other potential acquisitions.

                               THE EXCHANGE OFFER

TERMS OF THE EXCHANGE OFFER; PERIOD FOR TENDERING OLD NOTES

     Upon the terms and subject to the conditions  set forth in this  Prospectus
and in the  accompanying  Letter of Transmittal  (which together  constitute the
Exchange  Offer),  the  Company  will  accept for  exchange  Old Notes which are
properly  tendered  on or prior to the  Expiration  Date  and not  withdrawn  as
permitted below. As used herein, the term "Expiration Date" means 5:00 p.m., New
York City time, on February __, 1997; provided, however, that if the Company, in
its sole  discretion,  has  extended  the period of time for which the  Exchange
Offer is open,  the term  "Expiration  Date"  means the latest  time and date to
which the Exchange Offer is extended.

     As of the date of this Prospectus,  $375,000,000 aggregate principal amount
of the Old 8.50% Notes and  $125,000,000  aggregate  principal amount of the Old
8.875% Debentures was outstanding. This Prospectus,  together with the Letter of
Transmittal,  is first  being  sent on or about  the date set forth on the cover
page to all  Holders  of Old Notes at the  addresses  set forth in the  security
register  with respect to Old Notes  maintained  by the Trustee.  The  Company's
obligations  to accept Old Notes for exchange  pursuant to the Exchange Offer is
subject to certain  conditions  as set forth under  "Certain  Conditions  to the
Exchange Offer" below. 

     The Company expressly reserves the right, at any time or from time to time,
to extend  the  period of time  during  which the  Exchange  Offer is open,  and
thereby delay  acceptance of any Old Notes,  by giving oral or written notice of
such extension to the Exchange Agent and notice of such extension to the Holders
as described below. During any such extension, all Old Notes previously tendered
will remain  subject to the  Exchange  Offer and may be accepted for exchange by
the  Company.  Any Old Notes not  accepted  for  exchange for any reason will be
returned  without  expense  to the  tendering  Holder  thereof  as  promptly  as
practicable after the expiration or termination of the Exchange Offer.

     The Company expressly reserves the right to amend or terminate the Exchange
Offer, and not to accept for exchange any Old Notes not theretofore accepted for
exchange,  upon the  occurrence of any of the  conditions of the Exchange  Offer
specified  below under "Certain  Conditions to the Exchange  Offer." The Company
will give oral or written notice of any extension, amendment,  non-acceptance or
termination  to the Holders of the Old Notes as promptly  as  practicable,  such
notice in the case of any  extension to be issued by means of a press release or
other public  announcement  no later than 9:00 a.m.,  New York City time, on the
next business day after the previously scheduled Expiration Date.

     Holders of Old Notes do not have any appraisal or dissenters'  rights under
the  General  Corporation  Law of the  State of  Delaware  or the  Indenture  in
connection with the Exchange Offer.  The Company intends to conduct the Exchange
Offer in accordance with the applicable requirements of the Exchange Act and the
rules and regulations of the SEC thereunder.


PROCEDURES FOR TENDERING OLD NOTES

     The  tender to the  Company  of Old Notes by a Holder  thereof as set forth
below and the  acceptance  thereof  by the  Company  will  constitute  a binding
agreement  between  the  tendering  Holder  and the  Company  upon the terms and
subject to the conditions set forth in this  Prospectus and in the  accompanying
Letter of Transmittal.  Except as set forth below, a Holder who wishes to tender
Old Notes for exchange  pursuant to the Exchange  Offer must transmit a properly
completed and duly executed Letter of Transmittal, including all other documents
required by such Letter of  Transmittal,  to The First  National Bank of Chicago
(the "Exchange  Agent") at one of the addresses set forth below under  "Exchange
Agent" on or prior to the Expiration  Date (or comply with  guaranteed  delivery
procedures described below on or prior to the Expiration Date). In addition, (i)
certificates  for such Old Notes must be  received by the  Exchange  Agent along
with the  Letter of  Transmittal,  (ii) a timely  confirmation  of a  book-entry
transfer (a "Book-Entry  Confirmation")  of such Old Notes, if such procedure is
available,  into the Exchange  Agent's  account at The Depository  Trust Company
(The "Book-Entry  Transfer  Facility")  pursuant to the procedure for book-entry
transfer  described  below,  must be received by the Exchange Agent prior to the
Expiration  Date or (iii) the Holder must comply  with the  guaranteed  delivery
procedures described below.


                                       25

<PAGE>


     THE METHOD OF DELIVERY OF OLD NOTES,  LETTERS OF TRANSMITTAL  AND ALL OTHER
REQUIRED  DOCUMENTS IS AT THE  ELECTION  AND RISK OF THE HOLDERS AND,  EXCEPT AS
OTHERWISE  PROVIDED BELOW, WILL BE DEEMED MADE ONLY WHEN ACTUALLY  RECEIVED.  IF
SUCH DELIVERY IS BY MAIL,  IT IS  RECOMMENDED  THAT  REGISTERED  MAIL,  PROPERLY
INSURED, WITH RETURN RECEIPT REQUESTED,  BE USED. IN ALL CASES,  SUFFICIENT TIME
SHOULD BE ALLOWED TO ASSURE TIMELY  DELIVERY.  NO LETTERS OF  TRANSMITTAL OR OLD
NOTES SHOULD BE SENT TO THE COMPANY. 

     Signatures on a Letter of  Transmittal  or a notice of  withdrawal,  as the
case may be, must be guaranteed  unless the Old Notes  surrendered  for exchange
pursuant  thereto are tendered  (i) by a registered  Holder of the Old Notes who
has not completed the box entitled "Special  Issuance  Instructions" or "Special
Delivery  Instructions"  on the Letter of Transmittal or (ii) for the account of
an Eligible  Institution (as defined  below).  In the event that signatures on a
Letter  of  Transmittal  or a notice  of  withdrawal,  as the  case may be,  are
required to be guaranteed,  such  guarantees must be by a firm which is a member
of a  registered  national  securities  exchange  or a  member  of the  National
Association of Securities Dealers, Inc. or by a commercial bank or trust company
having an office or correspondent in the United States (collectively,  "Eligible
Institutions").  If Old Notes are  registered in the name of a person other than
the person  signing the Letter of  Transmittal,  the Old Notes  surrendered  for
exchange  must be endorsed  by, or be  accompanied  by a written  instrument  or
instruments of transfer or exchange,  in satisfactory  form as determined by the
Company in its sole discretion,  duly executed by the registered Holder with the
signature thereon guaranteed by an Eligible Institution.

     If the Letter of  Transmittal  or any Old Notes or powers of  attorney  are
signed by trustees,  executors,  administrators,  guardians,  attorneys-in-fact,
officers  or  corporations  or others  acting in a fiduciary  or  representative
capacity,  such person should so indicate when signing and, unless waived by the
Company,  proper evidence satisfactory to the Company of its authority to so act
must be submitted. 

     All  questions as to the validity,  form,  eligibility  (including  time of
receipt) and acceptance of Old Notes tendered for exchange will be determined by
the  Company  in its sole  discretion,  which  determination  shall be final and
binding.  The Company  reserves the absolute right to reject any and all tenders
of  any  particular  Old  Notes  not  properly  tendered  or to not  accept  any
particular Old Notes which  acceptance  might, in the judgment of the Company or
its counsel,  be unlawful.  The Company also reserves the absolute  right in its
sole  discretion  to waive any defects or  irregularities  or  conditions of the
Exchange  Offer as to any  particular  Old  Notes  either  before  or after  the
Expiration  Date (including the right to waive the  ineligibility  of any Holder
who seeks to tender Old Notes in the Exchange Offer).  The interpretation of the
terms and conditions of the Exchange Offer as to any particular Old Notes either
before or after the Expiration Date (including the Letter of Transmittal and the
instructions  thereto) by the Company shall be final and binding on all parties.
Unless waived,  any defects or  irregularities in connection with the tenders of
Old Notes for exchange  must be cured within such  reasonable  period of time as
the Company shall  determine.  Neither the Company,  the Exchange  Agent nor any
other  person  shall be under  any duty to give  notification  of any  defect or
irregularity with respect to any tender of Old Notes for exchange, nor shall any
of them incur any liability for failure to give such notification.

     By tendering,  each Holder will represent to the Company that,  among other
things,  (i) the New Notes  acquired  pursuant to the  Exchange  Offer are being
acquired in the  ordinary  course of business of the person  receiving  such New
Notes, whether or not such person is the Holder, (ii) neither the Holder nor any
such  other  person  has an  arrangement  or  understanding  with any  person to
participate in the distribution of such New Notes,  (iii) if the Holder is not a
broker-dealer,  or is a broker-dealer but will not receive New Notes for its own
account in exchange for Old Notes,  neither the Holder not any such other person
is engaged in or intends to  participate in the  distribution  of such New Notes
and (iv)  neither  the Holder nor any such other  person is an  "affiliate,"  as
defined under Rule 405 of the Securities  Act, of the Company.  If the tendering
Holder is a  broker-dealer  that will  receive New Notes for its owns account in
exchange  for  Old  Notes  that  were  acquired  as a  result  of  market-making
activities or other trading activities,  it will be required to acknowledge that
it will deliver a prospectus in connection with any resale of such New Notes.



                                       26
<PAGE>


     No  alternative,  conditional,  irregular  or  contingent  tenders  will be
accepted.  All tendering Holders,  by execution of the Letter of Transmittal (or
facsimile thereof), shall waive any right to receive notice of the acceptance of
the Old Notes for exchange.


ACCEPTANCE OF OLD NOTES FOR EXCHANGE; DELIVERY OF NEW NOTES

     Upon satisfaction or waiver of all of the conditions to the Exchange Offer,
the Company will  accept,  promptly  after the  Expiration  Date,  all Old Notes
properly  tendered and will issue the New Notes promptly after acceptance of the
Old Notes. See "Certain Conditions to the Exchange Offer" below. For purposes of
the  Exchange  Offer,  the  Company  shall be deemed to have  accepted  properly
tendered  Old Notes for exchange  when,  as and if the Company has given oral or
written notice thereof to the Exchange Agent.

     In all cases,  issuance  of New Notes for Old Notes that are  accepted  for
exchange  pursuant to the Exchange  Offer will be made only after timely receipt
by the Exchange Agent of certificates for such Old Notes or a timely  Book-Entry
Confirmation  of such  Old  Notes  into  the  Exchange  Agent's  account  at the
Book-Entry  Transfer  Facility  pursuant to the book-entry  transfer  procedures
described  below, a properly  completed and duly executed  Letter of Transmittal
and all other required documents. If any tendered Old Notes are not accepted for
any reason set forth in the terms and  conditions  of the  Exchange  Offer or if
certificates representing Old Notes are submitted for a greater principal amount
than the Holder desires to exchange,  such unaccepted or non-exchanged Old Notes
will be returned  without  expense to the tendering  Holder  thereof (or, in the
case of Old Notes  tendered by  book-entry  transfer  into the Exchange  Agent's
account at the Book-Entry  Transfer Facility pursuant to the book-entry transfer
procedures  described below, such non-exchanged Old Notes will be credited to an
account  maintained  with such  Book-Entry  Transfer  Facility)  as  promptly as
practicable after the expiration or termination of the Exchange Offer.


INTEREST ON THE NEW NOTES

     The  New  Notes  will  bear  interest   from  October  29,  1997,   payable
semiannually on May 1 and December 1 of each year, commencing on May 1, 1998, at
the rate of 8.50% per  annum in the case of the New 8.50%  Notes and at the rate
of 8.875% per annum in the case of the 8.875%  Debentures.  Holders of Old Notes
whose Old Notes are  accepted  for  exchange  will be deemed to have  waived the
right to receive any  payment in respect of  interest  on the Old Notes  accrued
from  October  29,  1997  until  the  date of the  issuance  of the  New  Notes.
Consequently,  holders who  exchange  their Old Notes for New Notes will receive
the same interest  payment on May 1, 1998 (the first interest  payment date with
respect to the Old Notes and the New Notes)  that they would have  received  had
they not accepted the Exchange Offer. 


BOOK-ENTRY TRANSFER

     The Exchange Agent will make a request to establish an account with respect
to the Old  Notes  at the  Book-Entry  Transfer  Facility  for  purposes  of the
Exchange  Offer  promptly  after  the  date of this  Prospectus.  Any  financial
institution that is a participant in the Book-Entry  Transfer Facility's systems
may make  book-entry  delivery  of  Notes by  causing  the  Book-Entry  Transfer
Facility to transfer such Notes into the Exchange  Agent's account in accordance
with the Book-Entry Transfer Facility's  Automated Tender Offer Program ("ATOP")
procedures  for transfer.  However,  the exchange for the Notes so tendered will
only be made after timely confirmation of such book-entry transfer of Notes into
the Exchange  Agent's  account,  and timely  receipt by the Exchange Agent of an
Agent's  Message  (as such term is defined in the next  sentence)  and any other
documents  required by the Letter of  Transmittal.  The term  "Agent's  Message"
means a message, transmitted by the Book-Entry Transfer Facility and received by
the Exchange Agent and forming a part of a Book-Entry Confirmation, which states
that the  Book-Entry  Transfer  Facility has received an express  acknowledgment
from a  participant  tendering  Notes that are the  subject  of such  Book-Entry
Confirmation  that such  participant  has received and agrees to be bound by the
terms of the  Letter of  Transmittal,  and that the  Company  may  enforce  such
agreement against such participant.

GUARANTEED DELIVERY PROCEDURES

     If a  registered  Holder of the Old Notes  desires to tender such Old Notes
and the Old Notes are not  immediately  available,  or time will not permit such
Holder's  Old Notes or other  required  documents  to reach the  Exchange  Agent
before the Expiration  Date, or the procedure for book-entry  transfer cannot be
completed on a timely basis,  a tender may be effected if (i) the tender is made
through an Eligible  Institution,  (ii) on or prior to the Expiration  Date, the
Exchange Agent receives from such Eligible  Institution a properly completed and
duly executed Notice of Guaranteed Delivery,  substantially in the form provided
by the Company (by telegram,  facsimile  transmission,  mail or hand  delivery),
setting  forth the name and address of the Holder of Old Notes and the amount of
Old  Notes  tendered,  stating  that  the  tender  is  being  made  thereby  and
guaranteeing  that within five New York Stock  Exchange  ("NYSE")  trading  days
after  the  date  of  execution  of  the  Notice  of  Guaranteed  Delivery,  the
certificates of all physically  tendered Old Notes, in proper form for transfer,
or a Book-Entry Confirmation,  as the case may be, a properly completed and duly
executed  Letter of Transmittal  (or facsimile  thereof) and any other documents
required  by the  Letter  of  Transmittal  will  be  deposited  by the  Eligible
Institution  with  the  Exchange  Agent,  and  (iii)  the  certificates  for all
physically  tendered  Old Notes,  in proper form for  transfer,  or a Book-Entry
Confirmation,  as the case may be, a properly completed and duly executed Letter
of Transmittal (or a facsimile thereof), and all other documents required by the
Letter of  Transmittal,  are  received by the  Exchange  Agent  within five NYSE
trading days after the date of execution of the Notice of Guaranteed Delivery.


WITHDRAWAL RIGHTS

     Tenders of Old Notes may be withdrawn  at any time prior to the  Expiration
Date.

     For a  withdrawal  to be  effective,  a written,  telegraphic  or facsimile
notice  of  withdrawal  must be  received  by the  Exchange  Agent at one of the
addresses set forth below under "Exchange  Agent." Any such notice of withdrawal
must  specify  the  name of the  person  having  tendered  the Old  Notes  to be
withdrawn,  identify  the Old Notes to be  withdrawn  (including  the  principal
amount of such Old  Notes),  and  (where  certificates  for Old Notes  have been
transmitted)  specify  the  name in which  such Old  Notes  are  registered,  if
different  from that of the  withdrawing  Holder,  must include a statement that
such Holder is  withdrawing  its election to have such Old Notes  exchanged  and
must be signed by the Holder in the same manner as the original signature on the
Letter of  Transmittal  (including  any  required  signature  guarantees)  or be
accompanied by evidence  satisfactory to the Company than the person withdrawing
the tender has  succeeded  to the  beneficial  ownership  of the Old Notes being
withdrawn.  If  certificates  for Old Notes  have been  delivered  or  otherwise
identified  to  the  Exchange  Agent,   then,  prior  to  the  release  of  such
certificates,  the withdrawing Holder must also submit the serial numbers of the
particular  certificates  to be  withdrawn.  If Old  Notes  have  been  tendered
pursuant to the procedure for book-entry  transfer  described above, any note of
withdrawal  must  specify the name and number of the  account at the  Book-Entry
Transfer  Facility to be credited  with the  withdrawn  Old Notes and  otherwise
comply with the procedures of such  facility.  All questions as to the validity,
form  and  eligibility  (including  time of  receipt)  of such  notices  will be
determined by the Company, whose determination shall be final and binding on all
parties.  Any Old Notes so  withdrawn  will be deemed  not to have been  validly
tendered for exchange  for purposes of the Exchange  Offer.  Any Old Notes which
have been  tendered for exchange but which are not exchanged for any reason will
be returned to the Holder  thereof  without cost to such Holder (or, in the case
of Old Notes tendered by book-entry  transfer into the Exchange  Agent's account
at  the  Book-Entry  Transfer  Facility  pursuant  to  the  book-entry  transfer
procedures  described  above,  such Old Notes  will be  credited  to an  account
maintained with such Book-Entry  Transfer Facility for the Old Notes) as soon as
practicable after withdrawal, rejection of tender or termination of the Exchange
Offer.  Properly  withdrawn  Old Notes may be retendered by following one of the
procedures  described  under  "Procedures  for Tendering Old Notes" above at any
time on or prior to the Expiration Date. 


CERTAIN CONDITIONS TO THE EXCHANGE OFFER

     Notwithstanding  any other  provisions of the Exchange  Offer,  the Company
shall not be required to accept for exchange,  or to issue New Notes in exchange
for, any Old Notes and may terminate or amend


                                       28
<PAGE>

the Exchange  Offer,  if at any time before the acceptance of such Old Notes for
exchange or the exchange of the New Notes for such Old Notes, such acceptance or
issuance would violate  applicable law or any interpretation of the staff of the
SEC.

     The  foregoing  condition is for the sole benefit of the Company and may be
asserted  by the Company  regardless  of the  circumstances  giving rise to such
condition  or may be waived by the  Company  in whole or in part at any time and
from time to time in its sole discretion. The failure by the Company at any time
to exercise the foregoing  rights shall not be deemed a waiver of any such right
and each such right  shall be deemed an ongoing  right  which may be asserted at
any time and from time to time.

     In  addition,  the  Company  will not  accept  for  exchange  any Old Notes
tendered, and no New Notes will be issued in exchange for any such Old Notes, if
at such time any stop order shall be threatened or in effect with respect to the
Registration  Statement  of  which  this  Prospectus  constitutes  a part or the
qualification of the Indenture under the Trust Indenture Act of 1939, as amended
(the "TIA").

TRANSFER TAXES

     Holders who tender  their Old Notes for  exchange  will not be obligated to
pay any  transfer  taxes in  connection  therewith,  except that (i) Holders who
instruct  the Company to register  New Notes in the name of, or request that Old
Notes not  tendered or not  accepted  in the  Exchange  Offer be returned  to, a
person other than the registered  tendering  Holder will be responsible  for the
payment of any  applicable  transfer  tax thereon and (ii) if a transfer  tax is
imposed  for any reason  other than the  transfer of Old Notes to the Company or
its order pursuant to the Exchange Offer, the Holder will be responsible for the
payment of any such taxes (whether imposed on the registered Holder or any other
person). 


CONSEQUENCES OF FAILURE TO EXCHANGE

     Holders  of Old  Notes  who do not  exchange  their Old Notes for New Notes
pursuant to the Exchange  Offer will continue to be subject to the  restrictions
on  transfer of such Old Notes as set forth in the legend  thereon.  In general,
the Old Notes may not be offered or sold, unless registered under the Securities
Act,  except  pursuant to an exemption from, or in a transaction not subject to,
the Securities Act and applicable  state  securities  laws. The Company does not
intend to register the Old Notes under the Securities Act. The Company  believes
that, based upon interpretations contained in letters issued to third parties by
the  staff of the SEC,  New  Notes  issued  pursuant  to the  Exchange  Offer in
exchange  for  Old  Notes  may  be  offered  for  resale,  resold  or  otherwise
transferred  by each Holder thereof  (other than a  broker-dealer,  as set forth
below,  and any such Holder which is an  "affiliate"  of the Company  within the
meaning  of Rule 405 under  the  Securities  Act)  without  compliance  with the
registration and prospectus  delivery  provisions of the Securities Act provided
that  such New Notes  are  acquired  in the  ordinary  course  of such  Holder's
business and such Holder has no arrangement or understanding  with any person to
participate  in the  distribution  of such  New  Notes.  If any  Holder  has any
arrangement or  understanding  with respect to the distribution of the New Notes
to be acquired pursuant to the Exchange Offer, such Holder (i) could not rely on
the applicable interpretations of the staff of the SEC and (ii) must comply with
the registration and prospectus  delivery  requirements of the Securities Act in
connection with any resale  transaction.  Each  broker-dealer  that receives New
Notes for its own account in  exchange  for Old Notes must  acknowledge  that it
will deliver a prospectus in connection  with any resale of such New Notes.  See
"Plan of  Distribution."  In  addition,  to comply with the  securities  laws of
certain jurisdictions,  if applicable,  the New Notes may not be offered or sold
unless they have been  registered or qualified for sale in such  jurisdiction or
an exemption from  registration  or  qualification  is available and is complied
with.  The Company does not  currently  intend to take any action to register or
qualify the New Notes for resale in any such jurisdictions.

                              DESCRIPTION OF NOTES

     The New 8.50% Notes and the New 8.875%  Debentures  will each be a separate
series of debt securities to be issued under an Indenture  (hereinafter referred
to as the "Indenture") dated as of October 29, 1997, between the Company and The
First  National Bank of Chicago  (hereinafter  referred to as the  "Trustee") as
amended by the First  Supplemental  Indenture  dated as of  November  21,  1997,
copies  of each of which  have  been  filed as an  exhibit  to the  Registration
Statement of which this Prospectus  constitutes a part. The following summary of
certain  provisions  of the  Indenture  does not purport to be  complete  and is
subject to, and is qualified in its entirety by reference to, all the provisions
of the Indenture,  including the  definitions of certain terms therein and those
terms  made a part  thereof  by the Trust  Indenture  Act of 1939,  as  amended.
Wherever particular defined terms of the Indenture are referred to, such defined
terms shall be  incorporated  herein by reference.  A summary of certain defined
terms used in the Indenture and referred to in the following summary description
of the Notes is set forth  below  under  "Certain  Definitions".  The  following
summary of certain  provisions of the  Registration  Rights  Agreement  does not
purport to be  complete  and is subject  to, and  qualified  in its  entirety by
reference to, all of the provisions of the  Registration  Rights Agreement which
has  been  filed as an  exhibit  to the  Registration  Statement  of which  this
Prospectus constitutes a part.

     The terms of the New 8.50% Notes are identical in all material  respects to
the terms of the Old 8.50%  Notes and the  terms of the  8.875%  Debentures  are
identical in all material respects to the terms of the Old 8.875% Debentures, in
each case except for  certain  transfer  restrictions  and  registration  rights
relating  to the Old  Notes  and  except  that,  if the  Exchange  Offer  is not
consummated by April 27, 1998, Holders that have complied with their obligations
under the Registration  Rights  Agreements will be entitled,  subject to certain
exceptions,  to liquidated  damaged in an amount equal to 0.5% per annum held by
such Holder  until July 26, 1998 and  increasing  to an amount equal to 1.0% per
annum thereafter until the consummation of the Exchange Offer.


GENERAL

     The Notes will be general unsecured obligations of the Company subordinated
in right of payment to all Senior Debt of the Company. Initially the 8.50% Notes
will be  limited  to $375  million  aggregate  principal  amount  and the 8.875%
Debentures will be limited to $125 million aggregate principal amount.  However,
the Company has the right to issue additional 8.50% Notes and additional  8.875%
Debentures  under  the  Indenture  with  the  same  terms   including,   without
limitation, interest and interest payment rates, as the Notes offered hereby.

     Any such additional  8.50% Notes or 8.875%  Debentures  issued from time to
time by the Company shall  constitute part of the same series as the 8.50% Notes
or 8.875% Debentures, as the case may be, offered hereby.

     Principal of, and premium,  if any, on, the Notes will be payable,  and the
Notes may be exchanged or  transferred,  at the office or agency of the Trustee.
Interest  at the annual rate set forth on the cover page hereof will accrue from
October  29,  1997,  will  be  payable  semi-annually  on May 1 and  November  1
commencing  May 1, 1998, to the Holders  thereof at the close of business on the
preceding April 15 and October 15, respectively,  and, unless other arrangements
are made, will be paid by checks mailed to such Holders.

     The Notes will be issued only in fully  registered form in denominations of
$1,000 and any  multiple of $1,000.  No service  charge shall be payable for any
registration  of  transfer  or  exchange  of Notes,  but the Company may require
payment  of a sum  sufficient  to  cover  any  transfer  tax  or  other  similar
governmental charge payable in connection therewith.

OPTIONAL REDEMPTION

     The 8.50% Notes will be redeemable, at the Company's option, in whole or in
part, at any time on or after November 1, 2002, and prior to maturity,  upon not
less than 30 nor more than 60 days' prior notice,  at the  following  redemption
prices  (expressed in percentages of principal  amount)  ("Redemption  Prices"),
plus accrued interest to the date of redemption, if redeemed during the 12-month
period commencing on or after November 1 of the years set forth below: 
<TABLE>
<CAPTION>

                 YEAR                               REDEMPTION PRICE

                 2004.........................          101.417%
</TABLE>
     and, after November 1, 2005, at 100% of the principal amount.

     The 8.875% Debentures will be redeemable, at the Company's option, in whole
or in part,  at any time on or after  November 1, 2004,  and prior to  maturity,
upon not less than 30 nor more than 60 days' prior  notice,  at a price equal to
the sum of (i) par plus accrued interest to the date of redemption plus (ii) the
"Make-Whole Amount" if any.

     The term  "Make-Whole  Amount" shall mean, in connection  with any optional
redemption  of any 8.875%  Debenture,  the excess,  if any, of (i) the aggregate
present  value as of the date of such  redemption  of each  dollar of  principal
being redeemed and the amount of interest  (exclusive of interest accrued to the
date of  redemption)  that would have been  payable in respect of such dollar if
such prepayment had not been made,  determined by  discounting,  on a semiannual
basis,  such principal and interest at the Reinvestment  Rate (determined on the
Business  Day  immediately  preceding  the  date of such  redemption)  from  the
respective dates on which such principal and interest would have been payable if
such prepayment had not been made, over (ii) the aggregate  principal  amount of
the 8.875% Debentures being redeemed.

     The term  "Reinvestment  Rate" shall mean 0.50%  (one-half  of one percent)
plus the arithmetic mean of the yields under the respective headings "This Week"
and "Last Week" published in the Statistical Release under the caption "Treasury
Constant   Maturities"   for  the  maturity   (rounded  to  the  nearest  month)
corresponding  to the maturity of the principal  being  prepaid.  If no maturity
exactly  corresponds to such maturity,  yields for the two published  maturities
most closely  corresponding to such maturity shall be calculated pursuant to the
immediately  preceding  sentence and the Reinvestment Rate shall be interpolated
or extrapolated from such yields on a straight-line  basis,  rounding in each of
such relevant  periods to the nearest month.  For the purpose of calculating the
Reinvestment  Rate, the most recent  Statistical  Release published prior to the
date of determination of the Make-Whole Amount shall be used.

     The  term  "Statistical   Release"  shall  mean  the  statistical   release
designated "H.15(519)" or any successor publication which is published weekly by
the Federal Reserve System and which establishes  yields on actively traded U.S.
government  securities  adjusted to constant  maturities or, if such statistical
release is not published at the time of any  determination  under the Indenture,
then such other  reasonably  comparable  index which shall be  designated by the
Company.

     In  addition,  prior to  November  1,  2000 in the event  that the  Company
consummates  one or more offerings of its Qualified  Capital Stock,  the Company
may at its option,  use all or a portion of the proceeds  therefrom to redeem up
to 33% of the original aggregate principal amount at maturity of the 8.50% Notes
at a cash redemption price equal to 108.500% of the principal amount thereof and
up to 33% of the original aggregate principal amount of the 8.875% Debentures at
a cash redemption  price equal to 108.875% of the principal  amount thereof,  in
each  case,  plus  accrued  and  unpaid  interest  thereon  through  the date of
repurchase;  provided  that at least  $100  million  of the  original  aggregate
principal  amount  of the  8.50%  Notes and  $83.75  of the  original  aggregate
principal  amount  of  the  8.875%  Debentures,  as the  case  may  be,  remains
outstanding thereafter.

MANDATORY SINKING FUND

     The 8.875%  Debentures  are subject to mandatory  redemption  on a pro rata
basis on each November 1, commencing November 1, 2008, to and including November
1, 2026 (each, a "Mandatory  Sinking Fund Redemption  Date").  On each Mandatory
Sinking Fund Redemption Date, the Company shall redeem 8.875% Debentures with an
aggregate  principal  amount equal to $6.25  million  (subject to  adjustment as
described below, the "Mandatory Sinking Fund Payment Amount"); provided that the
Company's  obligation to redeem 8.875%  Debentures on any Mandatory Sinking Fund
Redemption  Date  shall be  deemed  satisfied  to the  extent  that the  Company
delivers or causes to be delivered to the Trustee for cancellation,  on or prior
to such Mandatory  Sinking Fund  Redemption  Date,  8.875%  Debentures,  if any,
acquired  during the  12-month  period  preceding  such  Mandatory  Sinking Fund
Redemption  Date.  The sinking fund  redemption  price is 100% of the  principal
amount of the 8.875%  Debentures being redeemed,  together with interest accrued
to the Mandatory Sinking Fund Payment Date.

     The Mandatory Sinking Fund Payment Amount shall be subject to adjustment in
the event that on or prior to any  Mandatory  Sinking Fund  Redemption  Date the
Company  delivers or causes to be  delivered  to the  Trustee  for  cancellation
8.875% Debentures with an aggregate  principal amount in excess of the Mandatory
Sinking  Fund Payment  Amount for such next  succeeding  Mandatory  Sinking Fund
Redemption  Date,  in which  case the  Mandatory  Sinking  Fund  Payment  Amount
applicable  to each  Mandatory  Sinking  Fund  Redemption  Date  after  the next
succeeding  Mandatory  Sinking Fund  Redemption Date shall be adjusted to be the
quotient  obtained  by dividing  (i) the  aggregate  principal  amount of 8.875%
Debentures  outstanding  after giving  effect to such  cancellation  by (ii) the
number of remaining  Mandatory  Sinking Fund Redemption Dates including the next
succeeding Mandatory Sinking Fund Redemption Date.


GLOBAL NOTES

     The Notes will be issued in the form of one or more fully registered global
notes (each a "Global Note") deposited with the Depositary or a nominee thereof.
Unless  and until it is  exchanged  in whole or in part for Notes in  definitive
registered  form, a Global Note may not be transferred  except as a whole 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 by the Depositary or any
such nominee to a successor of the Depositary or a nominee of such successor.

     Ownership  of  beneficial  interests  in a Global  Note will be  limited to
persons that have accounts with the Depositary  ("Participants") or persons that
may hold interests through Participants. Upon the issuance of a Global Note, the
Depositary for such Global Note will credit, on its book-entry  registration and
transfer  system,  the  Participants'  accounts  with the  respective  principal
amounts of the Notes represented by such Global Note beneficially  owned by such
Participants.  Ownership  of  beneficial  interests  in such Global Note will be
shown on, and the  transfer of such  ownership  interests  will only be effected
through,  records  maintained  by the  Depositary  (with respect to interests of
Participants)  and on the records of Participants  (with respect to interests of
persons holding through Participants).  The laws of some states may require that
certain  purchasers of securities  take physical  delivery of such securities in
definitive  form.  Such  limits  and such laws may  impair  the  ability to own,
transfer, or pledge beneficial interests in Global Notes.

     So long as the Depositary or its nominee is the owner of record of a Global
Note, the Depositary or such nominee, as the case may be, will be considered the
sole  owner or holder  of the  Notes  represented  by such  Global  Note for all
purposes  under the Indenture.  Except as set forth below,  owners of beneficial
interests in a Global Note will not be entitled to have the Notes represented by
such Global Note registered in their names,  and will not receive or be entitled
to receive  physical  delivery of such Notes in definitive  form and will not be
considered the owners or holders thereof under the Indenture.  Accordingly, each
person owning a beneficial interest in a Global Note must rely on the procedures
of the Depositary and, 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 of record under the Indenture.  The Company  understands that
under existing industry practices, if the Company requests any action of holders
or if any owner of a  beneficial  interest in a Global  Note  desires to give or
take any action which 


                                       33
<PAGE>


a holder is entitled to give or take under the Indenture,  the Depositary  would
authorize the Participants  holding the relevant beneficial interests to give or
take such action, and such Participants would authorize beneficial owners owning
through such  Participants  to give or take such action or would  otherwise  act
upon the instruction of beneficial owners holding through them.

     Payments  of  principal  of,  premium,   if  any,  and  interest  on  Notes
represented  by a Global Note  registered  in the name of the  Depositary or its
nominee will be made to such Depositary or such nominee,  as the case may be, as
the registered owner of such Global Note. None of the Company,  the Trustee,  or
any agent of the Company or agent of the Trustee will have any responsibility or
liability for any aspect of the records  relating to or payments made on account
of  beneficial  ownership  interests  in such  Global  Note or for  maintaining,
supervising,  or reviewing  any records  relating to such  beneficial  ownership
interests.

     The Company  expects  that the  Depositary,  upon receipt of any payment of
principal,  premium,  if any, or interest in respect of such Global  Note,  will
immediately credit Participants' accounts with payments in amounts proportionate
to their  respective  beneficial  interests  in such Global Note as shown on the
records  of  the   Depositary.   The  Company  also  expects  that  payments  by
Participants to owners of beneficial  interests in such Global Note held through
such  Participants  will be  governed  by  standing  customer  instructions  and
customary practices, as is now the case with securities held for the accounts of
customers  in  bearer  form or  registered  in  "street  name,"  and will be the
responsibility of such Participants.

     If the Depositary  notifies the Company that it is at any time unwilling or
unable to continue as Depositary or ceases to be eligible under  applicable law,
and a successor Depositary eligible under applicable law is not appointed by the
Company within 90 days, the Company will issue such Notes in definitive  form in
exchange for such Global Note.  In addition,  the Company may at any time and in
its sole discretion determine not to have any of the Notes represented by one or
more Global  Notes and, in such event,  will issue Notes in  definitive  form in
exchange for all of the Global Notes  representing  such Notes. Any Notes issued
in definitive form in exchange for a Global Note will be registered in such name
or names as the Depositary shall instruct the Trustee.  It is expected that such
instructions  will be based upon  directions  received  by the  Depositary  from
Participants  with respect to ownership of  beneficial  interests in such Global
Note.


SAME-DAY SETTLEMENT IN RESPECT OF GLOBAL NOTES

     So long as any Notes are represented by Global Notes registered in the name
of the  Depositary  or its  nominee,  such Notes will trade in the  Depositary's
Same-Day Funds Settlement  System, and secondary market trading activity in such
Notes will  therefore  be required by the  Depositary  to settle in  immediately
available  funds.  No  assurances  can be given  as to the  effect,  if any,  of
settlement in immediately available funds on trading activity in the Notes.


SUBORDINATION

     The payment of principal of, Change of Control purchase price,  premium, if
any, and  interest on the Notes 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 equivalents, of all Senior Debt.

     Upon  any  payment  or   distribution  of  assets  to  creditors  upon  any
liquidation, dissolution, winding up, receivership,  reorganization,  assignment
for the  benefit  of  creditors,  marshaling  of assets and  liabilities  or any
bankruptcy, insolvency or similar proceedings of the Company, the holders of all
Senior Debt will first be entitled to receive payment in full of all amounts due
or to become due  thereon  before the  Holders of the Notes will be  entitled to
receive any payment in respect of the principal  of, Change of Control  purchase
price, premium, if any, or interest on the Notes.

     No  payments on account of  principal,  Change of Control  purchase  price,
premium,  if any, or interest in respect of the Notes may be made by the Company
if there shall have  occurred  and be  continuing  a default in any payment with
respect to Senior Debt. In addition,  during the  continuance of any other event
of default (other than a payment default) with respect to Designated Senior Debt
pursuant to which the maturity  thereof may be  accelerated,  from and after the
date of receipt by the Trustee of 


                                       34
<PAGE>


written notice from the holders of such Designated  Senior Debt or from an agent
of such holders, no payments on account of principal, Change of Control purchase
price,  premium,  if any, or interest in respect of the Notes may be made by the
Company  for a period  ("Payment  Blockage  Period")  commencing  on the date of
delivery  of such notice and ending 179 days  thereafter  (unless  such  Payment
Blockage  Period shall be terminated  by written  notice to the Trustee from the
holders of such Designated Senior 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 Notes 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 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 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 such  subordination,  in the event of  insolvency,  funds that
would otherwise be payable to Holders will be paid to the holders of Senior Debt
to the extent  necessary to pay the Senior Debt in full,  and the Company may be
unable to meet fully its obligations with respect to the Notes.

     As of September  30, 1997,  on a pro forma basis after giving effect to the
Adjustments,  the Company had approximately $207 million in aggregate  principal
amount of Debt which would have  constituted  Senior Debt.  The Company  expects
from time to time to incur additional Debt  constituting  Senior Debt.  Although
the Indenture  contains  limitations on the amount of Debt which the Company may
incur,  the amount of such Debt could be substantial and, in any case, such Debt
may be Senior Debt. See "-- Covenants -- Limitation on Debt" below.

     In  addition,  the  Company  currently  conducts  substantially  all of its
operations  through  its  Subsidiaries.  The  rights  of  the  Company  and  its
creditors,   including  the  Holders  of  the  Notes,   to  participate  in  the
distribution   of  the  assets  of  any  Subsidiary   upon  any  liquidation  or
reorganization of such Subsidiary or otherwise will be effectively  subordinated
to, and subject to, the prior claims of creditors of such Subsidiary,  except to
the extent  that the  Company may itself be a creditor  with  recognized  claims
against the  Subsidiary.  The ability of the Company to pay principal of, Change
of Control  purchase price,  premium,  if any, and interest on the Notes will be
dependent upon the receipt of funds from its  Subsidiaries  by way of dividends,
fees,  interest,  loans or otherwise.  Most of the Company's  Subsidiaries  with
interests in a Power Supply Business  currently have in place, and the Indenture
will permit the Company's Subsidiaries to enter into, arrangements that restrict
their ability to make  distributions  to the Company by way of dividends,  fees,
interest,  loans and  otherwise.  As of September 30, 1997, on a pro forma basis
after  giving  effect  to  the  Adjustments,   the  Company's  Subsidiaries  had
approximately  $4.0 billion of  indebtedness  to which the Notes would have been
effectively subordinated. The Company expects its Subsidiaries from time to time
to incur additional Debt and the amount of such Debt could be substantial.


REGISTRATION RIGHTS

     Holders  of New Notes are not  entitled  in any  registration  rights  with
respect  to the  New  Notes.  Holders  of Old  Notes  are  entitled  to  certain
registration  rights  pursuant to the  Registration  Rights  Agreement.  AES has
agreed with the  Initial  Purchasers  pursuant to the terms of the  Registration
Rights Agreement, for the benefit of the Holders of the Old Notes, that AES will
use its  reasonable  best  efforts,  to file and  cause to  become  effective  a
registration  statement  (the "Exchange  Offer  Registration  Statement,")  with
respect to a registered offer to exchange the Old Notes for an issue of notes of
AES with terms  identical  to the Old Notes  (except that the New Notes will not
contain terms with respect to transfer  restrictions or the additional  interest
provisions  described below).  Upon such  registration  statement being declared
effective,  AES shall  offer the New Notes in return  for  surrender  of the Old
Notes.  The Exchange  Offer shall remain open for not less than 20 business days
after the date notice of the Exchange  Offer is mailed out to Holders of the Old
Notes. For each Old Note surrendered to AES under the Exchange Offer, the Holder
will receive a New Note of the same series and of equal  principal  amount.  The
Registration  Statement  of which  this  Prospectus  is a part  constitutes  the
Exchange Offer Registration Statement.



                                       35
<PAGE>


     In the event that applicable interpretations of the staff of the Commission
do not permit AES to effect the Exchange  Offer,  AES shall use its best efforts
to cause to become  effective a shelf  registration  statement  with  respect to
resales of the Notes (a "Shelf  Registration  Statement") and to keep such Shelf
Registration  Statement  effective until the earliest of (i) two years after the
Closing Date, (ii) the time when the Notes registered  thereunder can be sold by
non-affiliates  of AES  pursuant to Rule  144(k),  or (iii) such time as all the
Notes  have  been  sold  thereunder,  AES  shall,  in the  event of such a shelf
registration,  provide to each  Holder  copies of the  prospectus,  notify  each
Holder when a registration statement for the Notes has become effective and take
certain other actions as are required to permit resales of the Notes.

     In the event that (i) the Exchange Offer Registration  Statement (or in the
event the Exchange  Offer is not permitted  under  applicable  law or Commission
policy, a Shelf  Registration  Statement) is not filed with the Commission on or
prior to the 90th day  following  the Closing  Date,  (ii) such  Exchange  Offer
Registration  Statement is not declared  effective by the  Commission or a Shelf
Registration Statement is not filed with the Commission on or prior to the 150th
day following  the Closing Date of the Notes or (iii) the Exchange  Offer is not
consummated or a Shelf  Registration  Statement is not declared  effective on or
prior to the 180th day following  the Closing Date (each such event  referred to
in clauses (i)  through  (iii),  a  "Registration  Default"),  then AES will pay
additional  interest (in addition to the interest otherwise due on the Notes) to
each holder of the Notes during the first 90-day  period  immediately  following
the occurrence of each such Registration  Default in an amount equal to 0.5% per
annum  increasing  to an  amount  equal  to  1.0%  per  annum  thereafter.  Such
additional  interest  will cease  accruing  on such Notes when the  Registration
Default has been cured. 


COVENANTS

Limitation on Debt

     The Company will not Incur any Debt,  including  Acquisition  Debt,  unless
after  giving  effect  to the  Incurrence  of  such  Debt  and the  receipt  and
application  of the  proceeds  therefrom,  the Fixed Charge Ratio of the Company
would be  greater  than 2 to 1. The  Company's  obligation  to comply  with this
covenant will terminate if and when the Notes become Investment Grade.

     Notwithstanding  the  foregoing,  the Company may Incur each and all of the
following:  (i) Debt  under or in  respect of the Bank  Credit  Agreement  in an
aggregate  principal  amount  at any one time  outstanding  not to  exceed  $600
million;  (ii) Debt issued in exchange for, or the proceeds of which are used to
refinance,  outstanding  Notes or other Debt of the Company in an amount (or, if
such new Debt provides for an amount less than the principal  amount  thereof to
be due and payable upon a declaration of acceleration  thereof, with an original
issue price) not to exceed the amount so exchanged or  refinanced  (plus accrued
interest,  premium,  if any, and fees and expenses  related to such  exchange or
refinancing);  provided that (A) the date of any scheduled  payment of principal
by way of sinking fund, mandatory redemption or otherwise (including defeasance)
on any Debt so refinanced or exchanged  otherwise due after the final  scheduled
maturity  date of the Notes  shall not occur  prior to such  maturity  date as a
result of such  exchange or  refinancing  and (B) new Debt the proceeds of which
are used to exchange or refinance the Notes or other Debt of the Company that is
subordinated in right of payment to the Notes shall only be permitted under this
clause (ii) if (x) in case the Notes are exchanged or  refinanced in part,  such
new Debt, by its terms or by the terms of any  agreement or instrument  pursuant
to which such Debt is issued,  is expressly made pari passu with, or subordinate
in  right  of  payment  to,  the  remaining  Notes,  (y) in case  the Debt to be
exchanged or refinanced is subordinated  in right of payment to the Notes,  such
new Debt, by its terms or by the terms of any  agreement or instrument  pursuant
to which such Debt is issued,  is expressly made subordinate in right of payment
to the Notes, at least to the extent that the Debt to be exchanged or refinanced
is  subordinated  in right of payment to the Notes and (z) in case the Notes are
exchanged or  refinanced  in part or the Debt to be exchanged or  refinanced  is
subordinated  in right of payment  to the Notes,  as of the date the new Debt is
Incurred, the Average Life of the new Debt shall be equal to or greater than the
Average Life of the Notes or Debt to be exchanged or  refinanced;  (iii) Debt of
the Company to any of its Consolidated Subsidiaries, except that any transfer of
such Debt by a Consolidated  Subsidiary (other than to another Consolidated Sub-



                                       36

sidiary) will be deemed to be an Incurrence of Debt;  provided that such Debt is
expressly  subordinated  in right of payment  to the Notes;  and (iv) Debt in an
aggregate   principal  amount  not  to  exceed  $50  million  at  any  one  time
outstanding.

     For  purposes  of  determining  any  particular  amount of Debt  under this
"Limitation on Debt"  covenant,  Guarantees  of, or obligations  with respect to
letters of credit  supporting,  Debt otherwise  included in the determination of
such  particular  amount  shall not be  included.  For  purposes of  determining
compliance  with this  "Limitation on Debt"  covenant,  (A) in the event that an
item of Debt meets the criteria of more than one of the types of Debt  described
in the above clauses,  the Company, in its sole discretion,  shall classify such
item of Debt and only be required to include the amount and type of such Debt in
one of such  clauses  and (B) the amount of Debt  issued at a price that is less
than the principal  amount thereof shall be equal to the amount of the liability
in respect thereof determined in conformity with GAAP.


Limitation on Restricted Subsidiary Debt

     The Company will not permit any Restricted Subsidiary to Incur, directly or
indirectly,  any Debt,  including  Acquisition Debt. The Company's obligation to
comply with this covenant will terminate if and when the Notes become Investment
Grade.

     Notwithstanding  the  foregoing,  each and all of the following Debt may be
Incurred by a  Restricted  Subsidiary:  (i) Debt  outstanding  as of the Closing
Date;  (ii) Debt  Incurred for any purpose  (including  without  limitation  the
purposes set forth in clause  (iii)  below) to the extent of the amount  thereof
that is also Debt of the Company and is permitted under the "Limitation on Debt"
covenant  described  above;  (iii) Debt  Incurred  to finance  the  development,
acquisition,  construction,  maintenance,  working  capital  requirements in the
ordinary  course of business  consistent  with past  practice or  operation of a
Power  Supply  Business  or  Unrelated  Business  in which  the  Company  or any
Restricted Subsidiary has a direct or indirect interest;  provided that (a) such
Debt shall be permitted under this clause (iii) only to the extent of the amount
thereof which (x) is  Non-Recourse to the Company and (y) is Non-Recourse to any
other  Restricted  Subsidiary of the Company other than Restricted  Subsidiaries
which  represented less than 33% of the  Consolidated  EBITDA of the Company for
the Reference Period, and (b) upon the commencement of commercial  operations of
such  Power  Supply  Business  or, in the case of an  acquisition  of such Power
Supply Business or Unrelated  Business,  upon the date of such acquisition,  the
Company  directly or through its  Restricted  Subsidiaries  either (x) controls,
under  an  operating  and  management  agreement  or  otherwise,  the day to day
management and operation of the Power Supply  Business or Unrelated  Business so
financed or (y) has  significant  influence over the management and operation of
such Power Supply Business or Unrelated  Business;  (iv) Debt issued in exchange
for, or the proceeds of which are used to  refinance,  outstanding  Debt of such
Restricted  Subsidiary otherwise permitted under the Indenture in an amount (or,
if such new Debt provides for an amount less than the principal  amount  thereof
to be due and  payable  upon a  declaration  of  acceleration  thereof,  with an
original issue price) not to exceed the amount so exchanged or refinanced  (plus
accrued  interest,  premium,  if any,  and fees  and  expenses  related  to such
exchange or refinancing plus any principal amounts previously repaid);  provided
that (a) the new Debt shall be Non-Recourse to the Company to the same extent as
the Debt to be exchanged or refinanced,  (b) if such Restricted Subsidiary has a
direct or indirect interest in any Power Supply Business or Unrelated  Business,
the new Debt shall be  Non-Recourse  to any other  Restricted  Subsidiary of the
Company other than Restricted  Subsidiaries  which  represented less than 33% of
the Consolidated EBITDA of the Company for the Reference Period, (c) the date of
any scheduled payment of principal by way of sinking fund,  mandatory redemption
or  otherwise  (including  defeasance)  on any Debt so  refinanced  or exchanged
otherwise  due after the final  scheduled  maturity  date of the Notes shall not
occur prior to such maturity  date as a result of such  exchange or  refinancing
and (d) if the new Debt refinances principal amounts previously repaid, (x) such
new Debt shall be permitted  only if on the date such new Debt is Incurred,  the
Company  could  incur at least  $1 of Debt  under  the  first  paragraph  of the
"Limitation on Debt" covenant described above and (y) the proceeds from such new
Debt are not to be used to make any Restricted Payments;  (v) Guarantees of Debt
of the Company  under the Bank Credit  Agreement;  (vi) Debt Incurred to support
the  performance  obligations  of a Restricted  Subsidiary  engaged in providing
construction management or operat- 


                                       37
<PAGE>


ing services to a Power Supply  Business;  provided  that (a) such Debt shall be
permitted  under this clause (vi) only to the extent of the amount thereof which
is  Non-Recourse  to the Company  and is  Non-Recourse  to any other  Restricted
Subsidiary of the Company other than Restricted  Subsidiaries  which represented
less  than 33% of the  Consolidated  EBITDA  of the  Company  for the  Reference
Period,  and (b) upon the  commencement  of  commercial  operation of such Power
Supply Business or in the case of an acquisition of such Power Supply  Business,
upon  the  date of  such  acquisition,  the  Company  directly  or  through  its
Restricted  Subsidiaries either (x) controls,  under an operating and management
agreement or otherwise,  the day to day  management  and operation of such Power
Supply  Business  or (y) has  significant  influence  over  the  management  and
operation of such Power Supply  Business;  (vii) Debt in an aggregate amount for
all  Restricted  Subsidiaries  at any one time  outstanding of not more than $50
million  Incurred to finance the on-going  operation,  but not any  expansion or
improvement,  of a Power  Supply  Business or  Unrelated  Business in which such
Restricted Subsidiary has a direct or indirect interest; provided that such Debt
shall be permitted under this clause (vii) only to the extent it is Non-Recourse
to the Company and to any other Restricted  Subsidiary of the Company other than
Restricted  Subsidiaries  which  represented  less than 33% of the  Consolidated
EBITDA of the Company for the Reference  Period;  (viii) Debt of any  Restricted
Subsidiary  of the  Company  owed  to (A)  the  Company  or (B)  any  Restricted
Subsidiary  of the  Company;  (ix) Debt in respect  of  Currency  Agreements  or
Interest  Rate  Agreements;  (x) Debt that is  Non-Recourse  to the  Company and
Non-Recourse  to any other  Restricted  Subsidiary  of the  Company  other  than
Restricted  Subsidiaries  which  represented  less than 33% of the  Consolidated
EBITDA of the  Company  for the  Reference  Period,  only to the extent that the
proceeds of such Debt are  received by the  Company or an  Intermediate  Holding
Company  as a  result  of such  proceeds  being  used to pay  dividends  or make
distributions  on the Capital Stock of such Restricted  Subsidiary and any other
Restricted  Subsidiary  in the chain of  ownership  between  the Company or such
Intermediate  Holding Company and such Restricted  Subsidiary;  (xi) Acquisition
Debt and Debt incurred to finance the  acquisition  of a Power Supply  Business;
provided  that such  Acquisition  Debt and  other  Debt is  Non-Recourse  to the
Company  or  any  Person  that  was  a  Restricted  Subsidiary  of  the  Company
immediately  prior to such Incurrence;  and provided further that where any Debt
is incurred to finance the  acquisition of more than one Power Supply  Business,
all such  acquisitions  shall have occurred  within 180 days of each other;  and
(xii) Debt of the type described in clause (iii) of the  definition  thereof the
Incurrence  of which  causes a  corresponding  reduction  in any debt service or
other similar cash reserve required to be maintained in connection with any Debt
of such Restricted Subsidiary permitted by clause (iii) above and (to the extent
that the same  constitutes a  refinancing  of Debt  permitted  under such clause
(iii)),  clause (iv) above,  in each case,  only to the extent that the proceeds
from such  reserve  reduction  are  received by the  Company or an  Intermediate
Holding Company as a result of such proceeds being used to pay dividends or make
distributions  on the Capital Stock of such Restricted  Subsidiary and any other
Restricted  Subsidiary  in the chain of  ownership  between  the Company or such
Intermediate Holding Company and such Restricted Subsidiary.

     For purposes of determining  compliance with this "Limitation on Restricted
Subsidiary  Debt"  covenant,  (A) in the  event  that an item of Debt  meets the
criteria of more than one of the types of Debt  described in the above  clauses,
the Company,  in its sole discretion,  shall classify such item of Debt and only
be required  to include the amount and type of such Debt in one of such  clauses
and (B) the  amount of Debt  issued at a price  that is less than the  principal
amount thereof shall be equal to the amount of the liability in respect  thereof
determined in conformity with GAAP.


Limitation on Restricted Payments

     The Company will not,  and will not permit any  Restricted  Subsidiary  to,
directly or indirectly,  make any  Restricted  Payment if after giving effect to
such Restricted Payment: (a) an Event of Default or event that, after the giving
of notice or lapse of time or both would become an Event of Default,  shall have
occurred and be continuing,  (b) the Company could not Incur at least $1 of Debt
under the first paragraph of the  "Limitation on Debt" covenant  described above
or  (c)  the  aggregate  amount  expended  by the  Company  and  its  Restricted
Subsidiaries  for all  Restricted  Payments (the amount of any single or related
series of Restricted  Payments so expended or  distributed,  if in excess of $15
million and other than in cash,  to be  determined in good faith by the Board of
Directors, as evidenced by a Board 


                                       38
<PAGE>


resolution)  after  April 1, 1997  shall  exceed  the sum of: (1) 50% of the Net
Income of the Company and its Consolidated Subsidiaries for the period (taken as
one accounting  period) beginning on April 1, 1997 and ending on the last day of
the fiscal  quarter for which  financial  information  is available  immediately
prior to the date of such  calculation;  provided  that if Net  Income  for such
period  is less  than  zero,  then  minus  100% of such net  loss;  plus (2) the
aggregate net proceeds  (including  the fair market value of proceeds other than
cash, as  determined in good faith by the Board of Directors,  as evidenced by a
Board resolution if the fair market value of such non-cash proceeds is in excess
of $15  million)  received by (A) the Company  from and after April 1, 1997 from
the  issuance and sale (other than to a  Restricted  Subsidiary)  of its Capital
Stock  (excluding  Redeemable  Stock,  but  including  Capital  Stock other than
Redeemable Stock issued upon conversion of, or in exchange for, Redeemable Stock
or securities other than its Capital Stock), and warrants, options and rights to
purchase its Capital Stock (other than Redeemable  Stock), but excluding the net
proceeds from the issuance,  sale, exchange,  conversion or other disposition of
its Capital Stock convertible  (unless solely at the option of the Company) into
(x) any security other than its Capital Stock or (y) its Redeemable Stock or (B)
a  Finance  Subsidiary  of the  Company  from and  after  April 1, 1997 from the
issuance and sale (other than to the Company or a Restricted  Subsidiary) of its
Qualified  Capital  Stock;  plus (3) to the  extent not  included  in clause (1)
above,  the net reduction in  Investments  of the type specified in clauses (iv)
through (vi) of the definition of Restricted  Payment resulting from payments of
interest on Debt, dividends, repayments of loans or advances, or other transfers
of assets to the Company or other Person that made the original  Investment from
the  Person in which  such  Investment  was made or  resulting  from the sale or
disposition of the Investment or other return of the amount of the Investment or
from  the   redesignation  of  any  Unrestricted   Subsidiary  as  a  Restricted
Subsidiary;  provided that such payment,  for purposes of the  calculation to be
made  pursuant to this clause (3),  shall not exceed the amount of the  original
Investment;  plus (4) any amount previously  included as a Restricted Payment on
account of an obligation by the Company or any  Restricted  Subsidiary to make a
Restricted  Payment  which  has not  actually  been made by the  Company  or any
Restricted  Subsidiary and which is no longer required to be paid by the Company
or any Restricted Subsidiary; plus (5) $502 million; provided that the foregoing
clause (c) shall not prevent the  payment of any  dividend  within 60 days after
the date of its declaration if such dividend could have been made on the date of
its  declaration  without  violation of the  provisions  of this  covenant.  For
purposes of clause  (c)(2) above,  the  aggregate  net proceeds  received by the
Company (x) from the issuance of its Capital  Stock upon the  conversion  of, or
exchange for, securities evidencing Debt of the Company,  shall be calculated on
the  assumption  that the gross  proceeds  from such  issuance  are equal to the
aggregate principal amount (or, if discount Debt, the accreted principal amount)
of the Debt evidenced by such securities converted or exchanged and (y) upon the
conversion or exchange of other  securities of the Company shall be equal to the
aggregate  net proceeds of the original  sale of the  securities so converted or
exchanged if such proceeds of such original sale were not previously included in
any calculation for the purposes of clause (c)(2) above plus any additional sums
payable upon  conversion or exchange.  The  Company's  obligation to comply with
this covenant shall terminate if and when the Notes become Investment Grade. The
amount  available to make  Restricted  Payments  calculated in  accordance  with
clause (c) of the first  sentence of this covenant is the same amount  available
under the equivalent provision  applicable to the Company's  outstanding 10 1/4%
Senior  Subordinated  Notes due 2006 and 8 3/8%  Senior  Subordinated  Notes due
2007.

     If an  Investment  which  the  Company  or  any  Restricted  Subsidiary  is
obligated  to make either in part from time to time or in whole in the future is
fixed in amount by the agreement setting forth such obligation,  for purposes of
determining  whether such Investment is a Restricted Payment permitted under the
foregoing covenant or is a Permitted Payment,  the Investment shall be deemed to
have been made only  once,  in the amount so fixed,  at the time the  obligation
first arises (and not when  payments in respect  thereof are later made).  If an
Investment  which the Company or any Restricted  Subsidiary is obligated to make
either  in part  from  time to time or in whole in the  future  is not  fixed in
amount  by  the  agreement  setting  forth  such  obligation,  for  purposes  of
determining  whether such Investment is a Restricted Payment permitted under the
foregoing covenant or is a Permitted Payment,  the Investment shall be deemed to
have  been  made at the time the  obligation  first  arises  in an  amount to be
determined  in good faith by the Board of  Directors,  as  evidenced  by a Board
resolution, and any actual payments in 


                                       39
<PAGE>


respect of such Investment shall be deemed to be Investments made on the date of
payment  thereof.  Subject  to the  terms of  clause  (v) of the  definition  of
Permitted Payments, such later Investments may be Permitted Payments.

     Restricted  Payments  are  defined in the  Indenture  to exclude  Permitted
Payments which include Permitted Investments. See "Certain Definitions" below.


Limitation on Restricted Subsidiary Investments and Mergers

     The Company will not permit any  Restricted  Subsidiary  with any direct or
indirect  interest in a Power Supply  Business to make any  Investment in, or to
consolidate or merge with,  any other Person with a direct or indirect  interest
in any other Power Supply Business or any Unrelated Business.  In addition,  the
Company will not permit any  Restricted  Subsidiary  with any direct or indirect
interest in any Unrelated  Business to make any Investment in, or to consolidate
or merge with, any other Person with a direct or indirect  interest in any Power
Supply Business or any other  Unrelated  Business.  The Company's  obligation to
comply  with  this  covenant  shall  terminate  if and  when  the  Notes  become
Investment Grade.

     The  foregoing  restrictions  shall not apply to any  Intermediate  Holding
Company;  provided that (i) each such Intermediate  Holding Company's direct and
indirect  interest in any Power Supply  Business or Unrelated  Business shall be
limited to the ownership of Capital Stock or Debt obligations of a Person with a
direct or indirect interest in such Power Supply Business or Unrelated Business;
(ii) no Intermediate  Holding Company shall incur,  assume,  create or suffer to
exist any Debt  (including any Guarantee of Debt) other than Debt to the Company
or Debt  permitted  under clauses (iii),  (viii) and (xi) of the  "Limitation on
Restricted  Subsidiary  Debt" covenant  described above; and (iii) no Lien shall
exist  upon any  assets of such  Intermediate  Holding  Company  whether  now or
hereafter  acquired,  except for Liens upon the  Capital  Stock of a  Restricted
Subsidiary of an Intermediate  Holding Company  securing Debt of such Restricted
Subsidiary and Liens securing Debt permitted under clauses (iii) and (xi) of the
"Limitation on Restricted Subsidiary Debt" covenant described above.


Limitation on Business

     The Company (a) will  continue,  and will cause each Material AES Entity to
continue, to engage in business of the same general type as now conducted by the
Company and its Restricted  Subsidiaries  and (b) will continue,  and will cause
each  Material  AES  Entity to  continue,  to operate  its and their  respective
businesses on a basis  substantially  consistent with the policies and standards
of the Company or such Material AES Entity as in effect on the Closing Date.


Limitations on Dividend and  Other  Payment  Restrictions  Affecting  Restricted
Subsidiaries

     The Company will not,  and will not permit any  Restricted  Subsidiary  to,
create or otherwise cause or suffer to exist or become  effective any consensual
encumbrance  or  restriction  of any  kind  on  the  ability  of any  Restricted
Subsidiary  to (i) pay  dividends or make any other  distributions  permitted by
applicable law on any Capital Stock of such Restricted  Subsidiary  owned by the
Company or any other Restricted Subsidiary, (ii) make payments in respect of any
Debt owed to the Company or any other Restricted Subsidiary, (iii) make loans or
advances to the Company or any other Restricted  Subsidiary or (iv) transfer any
of its Property to the Company or any other Restricted Subsidiary. The Company's
obligation  to comply with this  covenant  will  terminate if and when the Notes
become Investment Grade.

     This  covenant  shall  not  restrict  or  prohibit  any   encumbrances   or
restrictions  existing:  (i) in  connection  with  the  Incurrence  of any  Debt
permitted  under clause (iii),  (vi),  (vii),  (x) or (xi) of the "Limitation on
Restricted  Subsidiary  Debt"  covenant  described  above or with respect to any
portion  thereof  that is also  Debt of the  Company  and  permitted  under  the
"Limitation on Debt" covenant  described above;  provided that such encumbrances
or  restrictions  are  required  in order to effect such  financing  and are not
materially more restrictive,  taken as a whole, on the ability of the applicable
Restricted  Subsidiary to make the payments,  distributions,  loans, advances or
transfers  referred to in clauses (i) through  (iv) of the  preceding  paragraph
than encumbrances and restrictions, taken as a whole, customarily accepted (or,




                                       40
<PAGE>

in the absence of any industry custom,  reasonably  acceptable) in substantially
non-recourse  project  financing,  (ii) in  connection  with the  execution  and
delivery of an electric power or thermal energy purchase  contract to which such
Restricted  Subsidiary is the supplying party or other contracts with customers,
suppliers and  contractors  to which such  Restricted  Subsidiary is a party and
where such Restricted  Subsidiary is engaged in the  development,  construction,
acquisition  or  operation  of a  Power  Supply  Business;  provided  that  such
encumbrances or restrictions  are required in order to effect such contracts and
are not materially  more  restrictive,  taken as a whole,  on the ability of the
applicable  Restricted  Subsidiary to make the payments,  distributions,  loans,
advances or transfers  referred to in clauses (i) through (iv) in the  preceding
paragraph than  encumbrances  and  restrictions,  taken as a whole,  customarily
accepted (or, in the absence of any industry custom,  reasonably  acceptable) in
substantially  non-recourse  project  financing,  (iii) in  connection  with the
Incurrence  of any  Debt  permitted  under  clause  (iv) of the  "Limitation  on
Restricted  Subsidiary  Debt"  covenant  described  above,  provided  that  such
encumbrances  or  restrictions   taken  as  a  whole  are  not  materially  more
restrictive on the ability of the applicable  Restricted  Subsidiary to make the
payments, distributions, loans, advances or transfers referred to in clauses (i)
through  (iv) in the  preceding  paragraph  than  those that are then in effect,
taken as a whole, in connection  with the Debt so exchanged or refinanced,  (iv)
in connection with the Bank Credit Agreement and the project financing, electric
power  and  thermal  energy  purchase  arrangements  and  other  contracts  with
customers,  suppliers and  contractors in effect on the Closing Date,  including
extensions,  refinancings,  renewals or  replacements  thereof,  (v) pursuant to
customary  non-assignment  provisions in leases,  (vi) pursuant to  restrictions
imposed pursuant to any stock purchase or asset purchase  agreement  pending the
consummation of the transactions  contemplated thereby, (vii) in connection with
any  Acquisition  Debt,  provided that such  encumbrance or restriction  was not
incurred in contemplation of the obligor becoming a Restricted Subsidiary of the
Company,  which  encumbrance or restriction is not applicable to any Person,  or
the Property or assets of any Person,  other than the Person, or the Property or
assets, acquired, (viii) customary restrictions on transfers of Property subject
to a Lien which could not materially  adversely affect the Company's  ability to
satisfy its  obligations  under the Indenture  and the Notes or (ix)  provisions
contained  in  agreements  or  instruments  relating to Debt which  prohibit the
transfer of all or  substantially  all of the assets of the  obligor  thereunder
unless the  transferee  shall assume the  obligations  of the obligor under such
agreement or instrument, in each case; provided that, in the case of clause (iv)
above,  such  encumbrances  and  restrictions,  taken  as a  whole,  in any such
extensions,  refinancings,  renewals or  replacements  are not  materially  more
restrictive on the ability of the applicable  Restricted  Subsidiary to make the
payments, distributions, loans, advances or transfers referred to in clauses (i)
through (iv) in the preceding  paragraph than those encumbrances or restrictions
taken as a whole in  effect  immediately  before  such  extension,  refinancing,
renewal or replacement. The covenant shall not prevent the Company from granting
any Liens not expressly prohibited by this covenant.


Limitation on Additional Tiers of Senior Subordinated Debt

     The  Company  will not Incur or suffer to exist any Debt,  other  than Debt
evidenced by the Notes,  that is  subordinate  in right of payment to any Senior
Debt unless such Debt, by its terms or the terms of the  instrument  creating or
evidencing  it, is pari passu with, or  subordinate  in right of payment to, the
Notes;  provided  that  any  Debt  of the  Company  or  any  of  its  Restricted
Subsidiaries which is outstanding on the Closing Date shall be excluded from the
operation of this covenant.


Limitation on Asset Dispositions

     The  Company  will not  make,  and will not  permit  any of its  Restricted
Subsidiaries  to  make,  any  Asset  Disposition  unless  the  Company  (or  the
Restricted Subsidiary, as the case may be) receives consideration at the time of
each such  Asset  Disposition  at least  equal to the fair  market  value of the
shares or assets sold or  otherwise  disposed of (such  amounts in excess of $50
million  determined in good faith by the Board of  Directors,  as evidenced by a
Board resolution) and either (i) not less than 75% of the consideration received
by the Company  (or such  Restricted  Subsidiary,  as the case may be) is in the
form of cash or property or assets used or useful in a Power Supply  Business or
Capital Stock of a Person primarily engaged in a Power Supply Business, provided
that any note or other obligation re- 


                                       41
<PAGE>


ceived by the Company (or such Restricted  Subsidiary,  as the case may be) that
is  converted  into  cash  within  180 days of such  Asset  Disposition  and any
liabilities  (as shown on the  Company's or such  Restricted  Subsidiary's  most
recent  balance  sheet) of the  Company or any  Restricted  Subsidiary  that are
assumed  by the  transferee  of any such  assets  shall be deemed to be cash for
purposes of this clause (i), and (ii) first, the Net Cash Proceeds of such Asset
Disposition  are applied within 90 days from the later of the date of such Asset
Disposition or the receipt of Net Cash Proceeds related thereto,  to the payment
of the  principal  of,  premium  and  interest on any Senior Debt of the Company
(including to cash collateralize  letters of credit) and, in connection with any
such payment, any related loan commitment, standby facility or the like shall be
permanently  reduced in an amount  equal to the  principal  amount so repaid and
second, to the extent such Net Cash Proceeds are not required by the lenders, or
the terms, of the Senior Debt to be applied in accordance with the foregoing or,
if after being so applied there remain Net Cash Proceeds,  then at the Company's
election,  such Net Cash  Proceeds  are either (x)  invested in the  business or
businesses of the Company or any of its Restricted  Subsidiaries consistent with
the  "Limitation  on Business"  covenant  described  above;  provided  that such
investment  is made  within  365 days from the  later of the date of such  Asset
Disposition  or the  receipt  of the Net Cash  Proceeds  related  thereto or (y)
applied  to the  payment  of any  Senior  Debt  of the  Company  or  Debt of any
Restricted  Subsidiary or any Consolidated  Subsidiary  (other than Debt owed to
the Company or another Restricted Subsidiary),  and, in connection with any such
payment,  any related  loan  commitment,  standby  facility or the like shall be
permanently  reduced  in an amount  equal to the  principal  amount  so  repaid;
provided  that such Net Cash  Proceeds are so applied  within three months after
the  expiration  of the  365-day  period  referred to in clause (x) above or (z)
applied to make a tender offer (the "Offer") to purchase Notes and other Debt of
the Company from time to time outstanding with similar provisions  requiring the
Company to make an offer to purchase  or to redeem  such Debt with the  proceeds
from assets sales,  pro rata in proportion to the respective  principal  amounts
(or accreted  values in the case of Debt issued with an original issue discount)
of the Notes and such other Debt then outstanding at a purchase price of 100% of
their  principal  amount (or  accreted  value in the case of Debt issued with an
original issue  discount),  plus accrued  interest  (subject to proration in the
event of  oversubscription  in the manner set forth below).  Notwithstanding the
foregoing, to the extent that any or all of the Net Cash Proceeds of any Foreign
Asset  Disposition are prohibited or delayed by applicable  local law from being
repatriated to the U.S., the Company (or such Restricted Subsidiary, as the case
may be) shall not be required to apply the portion of such Net Cash  Proceeds so
affected in  accordance  with clause (ii) above (other than to repay Debt of the
Restricted  Subsidiary  making such Asset  Disposition or Debt of a Consolidated
Subsidiary of the Company, in each case as contemplated by clause (ii) above and
to the extent the prohibition or delay on repatriation is not applicable to such
repayment  and such  repayment  is not in  violation  of the terms of any Senior
Debt) (the Company hereby agreeing to cause the applicable Restricted Subsidiary
to promptly take all actions required by the applicable local law to permit such
repatriation);  provided  that once such  repatriation  of any such affected Net
Cash Proceeds is permitted  under the  applicable  local law, such  repatriation
will be  immediately  effected and such  repatriated  Net Cash  Proceeds will be
applied in the manner set forth in this  covenant.  To the extent that dividends
or  distributions  of any or all of the Net Cash  Proceeds of any Foreign  Asset
Disposition  would  result in a tax  liability  greater than that which would be
incurred if such Net Cash Proceeds were not so  dividended or  distributed,  the
Net Cash  Proceeds so affected  may be  retained  by the  applicable  Restricted
Subsidiary  for so long as such  adverse  tax  liability  would  continue  to be
incurred.

     Notwithstanding  anything in this covenant to the contrary, the Company and
any  Restricted  Subsidiary  may make the following  Asset  Dispositions:  (i) a
disposition  resulting from the bona fide exercise by governmental  authority of
its  claimed  or actual  power of  eminent  domain;  (ii) a  realization  upon a
security  interest;  (iii) any Permitted  Payment or Restricted  Payment that is
permitted  hereunder;  or (iv) any sale,  transfer,  conveyance,  lease or other
disposition of the Capital Stock or Property of a Restricted Subsidiary pursuant
to the terms of any power  sales  agreement  or steam sales  agreement  or other
agreement or contract related to the output or product of, or services  rendered
by, a Power  Supply  Business  as to which  such  Restricted  Subsidiary  is the
supplying  party;  provided  that to the  extent the  Company or any  Restricted
Subsidiary  receives  any cash  consideration  in  connection  with  such  Asset
Disposition,  the Net Cash Proceeds from such Asset Disposition shall be applied
in accordance with clause (ii) of this covenant. 


                                       42
<PAGE>


     If the aggregate  purchase price of Notes and other Debt tendered  pursuant
to an Offer  made  pursuant  to clause  (ii)(z) in the first  paragraph  of this
covenant description is less than the Net Cash Proceeds allotted to the purchase
of the Notes and other Debt, the Company may use the remaining Net Cash Proceeds
for general corporate purposes.  The Company will not be required to comply with
the provisions of clause (ii) in the first paragraph of this covenant if the Net
Cash Proceeds from one or more Asset Dispositions occurring on or after the date
of the  Indenture  are less than $40 million in any one fiscal year.  Any lesser
amounts so carried  forward and cumulated need not be segregated or reserved and
may be used for general corporate purposes.

     The  Company  will make such Offer by mailing to each  Holder of the Notes,
within  30 days  from  the  receipt  of Net  Cash  Proceeds,  a  written  notice
specifying the purchase date, which shall be not less than 30 days nor more than
60 days after the date of such notice (the  "Purchase  Date") and shall  contain
certain  information  concerning  the business of the Company  which the Company
believes  in good faith will enable the Holders of the Notes to make an informed
decision.  Holders  electing to have their Notes  purchased  will be required to
surrender such Notes at least one Business Day prior to the Purchase Date. If at
the  expiration  of the offer  period the  aggregate  principal  amount of Notes
surrendered  by Holders  exceeds the amount  available  to purchase  Notes,  the
Company will select the Notes to be purchased on a pro rata basis.

     In the event the  Company is unable to  purchase  Notes from  Holders in an
Offer  because of  provisions  of  applicable  law, the Company need not make an
Offer.  The  Company  shall then be  obligated  to use the Net Cash  Proceeds in
accordance  with clauses  (ii)(x) or (y) in the first paragraph of this covenant
description.

     The Company will comply with all applicable  tender offer rules,  including
without  limitation  Rule 14e-1 under the Exchange  Act, in  connection  with an
Offer under the provisions of this covenant.


Repurchase of Notes Upon a Change of Control

     Upon a Change of Control,  each Holder of the Notes shall have,  subject to
the provisions of  "Subordination"  above, the right to require that the Company
repurchase  such Holder's  Notes at a repurchase  price in cash equal to 101% of
the principal  amount thereof plus accrued and unpaid  interest,  if any, to the
date of repurchase. Certain of the events constituting a Change of Control under
the Notes will also  constitute  an event of default  under the  Company's  Bank
Credit  Agreement and, in any event,  the right of Holders to receive the Change
of Control  purchase price is subordinated in right of payment to the payment of
all Senior Debt, including Debt outstanding under the Bank Credit Agreement.  As
of  September  30,  1997,  on a pro  forma  basis  after  giving  effect  to the
Adjustments,  the Company had approximately $207 million in aggregate  principal
amount of Debt which would have  constituted  Senior  Debt.  Furthermore,  other
Senior Debt is permitted to be Incurred,  provided  certain  Fixed Charge Ratios
are met.  Due to the highly  leveraged  nature of the  Company,  there can be no
assurance that the Company will have sufficient funds to purchase tendered Notes
upon a Change of Control.

     The Change of Control provisions may not be waived by the Trustee or by the
Board of  Directors,  and any  modification  thereof  must be  approved  by each
Holder.  Nevertheless,  the Change of Control  provisions  will not  necessarily
afford protection to Holders,  including protection against an adverse effect on
the  value of the  Notes,  in the  event  that  the  Company  or its  Restricted
Subsidiaries  Incur  additional  Debt,  whether  through   recapitalizations  or
otherwise.  Furthermore, the Change of Control provisions will not be applicable
in the event of certain  transactions  with  Affiliates  of the Company that are
approved by the Board of Directors.  The Change of Control  provisions  will not
prevent a change in the Board of Directors which is approved by the then-present
members  of the  Board of  Directors.  See  "Certain  Definitions  --  Change of
Control"  below.  With  respect  to  a  sale  of  assets,  the  phrase  "all  or
substantially  all",  which appears in the definition of Change of Control,  has
not gained an established meaning. In interpreting this phrase, courts have made
subjective  determinations,  considering such factors as the value of the assets
conveyed  and the  proportion  of an entity's  income  derived from such assets.
Accordingly,  there may be  uncertainty  as to  whether a Holder  can  determine
whether a Change of Control has occurred  and can  exercise  any  remedies  such
Holder may have upon a Change of Control.



                                       43
<PAGE>


     Within 30 days  following  any Change of Control,  the Company shall mail a
notice to each Holder of the Notes with a copy to the Trustee stating (1) that a
Change of Control has occurred and that such Holder has the right to require the
Company to repurchase such Holder's Notes at a repurchase price in cash equal to
101% of the principal amount thereof plus accrued and unpaid  interest,  if any,
to the date of repurchase (the "Change of Control Offer"), (2) the circumstances
and relevant facts regarding such Change of Control (including  information with
respect  to pro forma  historical  income,  cash flow and  capitalization  after
giving effect to such Change of Control),  (3) the repurchase  date (which shall
be not  earlier  than 30 days or later than 60 days from the date such notice is
mailed) (the "Repurchase Date"), (4) that any Note not tendered will continue to
accrue  interest,  (5) that any Note accepted for payment pursuant to the Change
of Control Offer shall cease to accrue  interest after the Repurchase  Date, (6)
that Holders  electing to have a Note purchased  pursuant to a Change of Control
Offer will be required to surrender the Note, with the form entitled  "Option of
Holder to Elect  Purchase" on the reverse of the Note  completed,  to the paying
agent at the address  specified  in the notice prior to the close of business on
the  Repurchase  Date,  (7) that  Holders  will be entitled  to  withdraw  their
election if the paying agent  receives,  not later than the close of business on
the third Business Day (or such shorter periods as may be required by applicable
law) preceding the Repurchase Date, a telegram, telex, facsimile transmission or
letter setting forth the name of the Holder,  the principal  amount of Notes the
Holder  delivered for purchase,  and a statement that such Holder is withdrawing
his election to have such Notes  purchased,  and (8) that Holders which elect to
have their Notes  purchased only in part will be issued new Notes in a principal
amount equal to the unpurchased portion of the Notes surrendered.

     On the  Repurchase  Date, the Company shall (i) accept for payment Notes or
portions thereof tendered  pursuant to the Change of Control Offer, (ii) deposit
with the Trustee  money  sufficient  to pay the  purchase  price of all Notes or
portions  thereof so tendered and (iii)  deliver or cause to be delivered to the
Trustee Notes so accepted together with an officers' certificate identifying the
Notes or portions  thereof  tendered to the Company.  The Trustee shall promptly
mail to the Holders of the Notes so accepted  payment in an amount  equal to the
purchase price, and promptly authenticate and mail to such Holders a new Note in
a principal amount equal to any unpurchased portion of the Note surrendered. The
Company will publicly  announce the results of the Change of Control Offer on or
as soon as practicable after the Repurchase Date.

     The Company will comply with all applicable  tender offer rules,  including
without  limitation  Rule 14e-1 under the  Exchange  Act, in  connection  with a
Change of Control Offer.


Limitations on Transactions with Affiliates

     The  Company  will  not,  and  will  not  permit  any  of  its   Restricted
Subsidiaries to, directly or indirectly  enter into any transaction  (including,
without  limitation,  the sale, purchase or lease of any assets or properties or
the rendering of any services) involving aggregate consideration in excess of $5
million with any Affiliate  (other than a Person that  constitutes  an Affiliate
solely because of the Company's or a Subsidiary of the Company's control of such
Person except for any  Unrestricted  Subsidiary)  or holder of 5% or more of any
class of  Capital  Stock of the  Company  except  for  transactions  (including,
subject to the "Limitation on Restricted Payments" covenant described above, any
loans or advances by or to, or Guarantee on behalf of, any Affiliate or any such
holder)  made in good  faith the terms of which are fair and  reasonable  to the
Company or such Restricted  Subsidiary,  as the case may be, and are at least as
favorable as the terms which could be obtained by the Company or such Restricted
Subsidiary,  as  the  case  may  be,  in a  comparable  transaction  made  on an
arm's-length basis with Persons who are not such a holder or Affiliate; provided
that any such transaction shall be conclusively  deemed to be on terms which are
fair and reasonable to the Company or any of its Restricted  Subsidiaries and on
terms which are at least as favorable as the terms which could be obtained on an
arm's-length  basis with  Persons who are not such a holder or Affiliate if such
transaction  is approved by a majority of the Company's  directors  (including a
majority of the Company's  independent  directors);  and provided further,  that
with respect to the purchase or  disposition  of assets of the Company or any of
its Restricted Subsidiaries having a net book value in excess of $15 million, in
addition to  approval of its Board of  Directors,  the  Company  shall  obtain a
written  opinion of an Independent  Financial  Advisor stating that the terms of
such  transaction are fair to the Company or its Restricted  Subsidiary,  as the
case may be, from a 


                                       44
<PAGE>

financial point of view; and provided further that the fairness,  reasonableness
and  arm's-length  nature  of the  terms of any  transaction  which is part of a
series of related  transactions  may be  determined on the basis of the terms of
the series of related  transactions  taken as a whole.  This covenant  shall not
apply  to (a)  transactions  between  the  Company  or  any  of  its  Restricted
Subsidiaries  and  any  employee  of  the  Company  or  any  of  its  Restricted
Subsidiaries that are approved by the Board of Directors or any committee of the
Board of Directors consisting of the Company's  independent  directors,  (b) the
payment of reasonable and customary  regular fees to directors of the Company or
a Restricted Subsidiary,  (c) any transaction between the Company and any of its
Consolidated Subsidiaries or between any of its Consolidated  Subsidiaries,  (d)
any Permitted Payment and any Restricted Payment not otherwise prohibited by the
"Limitation  on  Restricted  Payments"  covenant  described  above  or  (e)  the
provision  of  general  corporate   administrative,   operating  and  management
services, including, without limitation, procurement,  construction engineering,
construction  administration,  legal, accounting,  financial,  money management,
risk management,  personnel,  administration and business planning services,  in
each case, in the ordinary course.


EVENTS OF DEFAULT

     An Event of Default,  as defined in the  Indenture  and  applicable  to the
8.50% Notes or the 8.875% Debentures, will occur with respect to the 8.50% Notes
or the 8.875%  Debentures,  as the case may be, if: (i) the Company  defaults in
the  payment of all or any part of  principal,  the  Change of Control  purchase
price or premium, if any, on any 8.50% Note or 8.875% Debenture, as the case may
be,  when the same  becomes  due and  payable at  maturity,  upon  acceleration,
redemption, mandatory repurchase, or otherwise; (ii) the Company defaults in the
payment of interest on any 8.50% Note or 8.875%  Debenture,  as the case may be,
when the same becomes due and payable,  and such default  continues for a period
of 30 days; (iii) an event of default, as defined in any indenture or instrument
evidencing or under which the Company or any  Significant  Subsidiary has at the
date of this  Indenture or shall  hereafter  have  outstanding  any Debt,  shall
happen and be continuing and either (a) such default results from the failure to
pay the  principal  of such Debt in excess of $50  million at final  maturity of
such Debt or (b) as a result of such  default,  the  maturity of such Debt shall
have been  accelerated so that the same shall be or become due and payable prior
to the date on which the same would  otherwise have become due and payable,  and
such  acceleration  shall not be  rescinded  or annulled  within 60 days and the
principal  amount of such Debt,  together with the principal amount of any other
Debt of the Company or any Significant Subsidiary in default, or the maturity of
which has been accelerated,  aggregates $50 million or more;  provided that such
default  shall not be an Event of Default if such Debt is Debt of a  Significant
Subsidiary, is Non-Recourse to the Company in respect of the amounts not paid or
due upon  acceleration  and the Company could, at the time of default,  incur at
least $1 of Debt under the "Limitation on Debt" covenant  described  above;  and
provided,  further however,  that,  subject to certain  provisions,  the Trustee
shall not be charged with  knowledge of any such default  unless  written notice
thereof shall have been given to the Trustee by the Company, by the holder or an
agent of the holder of any such  Debt,  by the  trustee  then  acting  under any
indenture or other instrument  under which such default shall have occurred,  or
by the  Holders of not less than 25% in the  aggregate  principal  amount of the
Notes at the time  outstanding;  (iv) the Company defaults in the performance of
or breaches any other covenant or agreement of the Company in the Indenture with
respect to the Notes or under the Notes and such default or breach continues for
a period of 60  consecutive  days after written  notice by the Trustee or by the
Holders of 25% or more in aggregate  principal  amount of the Notes;  (v) one or
more  judgments or orders shall be entered by a court against the Company or any
Significant Subsidiary for the payment of money in an amount which, individually
or in the aggregate exceeds $50 million (excluding the amount thereof covered by
insurance  or by a bond written by third  parties but treating any  deductibles,
self insurance or retentions as not so covered by insurance) and which judgments
or orders shall not be discharged or waived,  and shall remain  outstanding  and
there  shall  be any  period  of 60  consecutive  days  following  entry of such
judgment or order in excess of $50 million or the judgment or order which causes
the aggregate amount to exceed $50 million during which a stay of enforcement of
such judgment or order, by reason of a pending appeal or otherwise, shall not be
in  effect;  provided,  that such a judgment  or order  shall not be an Event of
Default if such judgment or order is against a Significant  Subsidiary  and does
not require any payment by the Company and the Company could,  at the expiration
of the 


                                       45
<PAGE>


applicable  60 day period,  incur at least $1 of Debt under the  "Limitation  on
Debt" covenant described above; (vi) a court having jurisdiction in the premises
enters a decree or order for (A) relief in respect of the  Company or any of its
Material  Subsidiaries in an involuntary  case under any applicable  bankruptcy,
insolvency,  or other similar law now or hereafter in effect, (B) appointment of
a receiver,  liquidator,  assignee, custodian, trustee, sequestrator, or similar
official  of the  Company  or any of its  Material  Subsidiaries  or for  all or
substantially  all of the  property  and  assets  of the  Company  or any of its
Material Subsidiaries or (C) the winding up or liquidation of the affairs of the
Company or any of its Material  Subsidiaries  and, in each case,  such decree or
order shall remain  unstayed and in effect for a period of 60 consecutive  days;
or (vii)  the  Company  or any of its  Material  Subsidiaries  (A)  commences  a
voluntary case under any applicable bankruptcy, insolvency, or other similar law
now or hereafter  in effect,  or consents to the entry of an order for relief in
an  involuntary  case under any such law, (B) consents to the  appointment of or
taking  possession  by a receiver,  liquidator,  assignee,  custodian,  trustee,
sequestrator,  or  similar  official  of the  Company  or  any  of its  Material
Subsidiaries or for all or  substantially  all of the property and assets of the
Company  or  any  of its  Material  Subsidiaries  or  (C)  effects  any  general
assignment for the benefit of creditors.

     If an Event of Default (other than an Event of Default specified in clauses
(vi) or (vii) above that occurs with respect to the Company) occurs with respect
to the Notes and is continuing under the Indenture,  then, and in each and every
such case either the  Trustee or the  Holders of not less than 25% in  aggregate
principal  amount of the Notes then  outstanding (or, in the case of an Event of
Default specified in clauses (i) or (ii) above, the Holders of not less than 25%
in the  aggregate  amount of the series so  affected)  by written  notice to the
Company  (and to the  Trustee  if such  notice  is  given  by the  Holders  (the
"Acceleration  Notice")),  may,  and the Trustee at the request of such  Holders
shall,  declare the principal of, premium,  if any, and accrued  interest on the
Notes to be immediately  due and payable.  Upon a declaration  of  acceleration,
such principal of, and accrued interest shall be immediately due and payable. If
an Event of Default specified in clauses (vi) or (vii) above occurs with respect
to the  Company,  the  principal  of,  and  accrued  interest  on the Notes then
outstanding shall ipso facto become and be immediately due and payable,  subject
to the prior  payment in full of all Senior  Debt,  without any  declaration  or
other act on the part of the  Trustee or any  Holder.  The Holders of at least a
majority in principal amount of the outstanding  Notes may, by written notice to
the Company and to the  Trustee,  waive all past  defaults  with  respect to the
Notes and rescind and annul a declaration  of  acceleration  with respect to the
Notes and its  consequences if (i) all existing Events of Default  applicable to
the Notes,  other than the  nonpayment  of the  principal  of, Change in Control
purchase  price or premium,  if any,  and interest on the Notes that have become
due solely by such  declaration of  acceleration,  have been cured or waived and
(ii) the rescission would not conflict with any judgment or decree of a court of
competent jurisdiction.

     The Holders of at least a majority  in  aggregate  principal  amount of the
outstanding  Notes may  direct the time,  method,  and place of  conducting  any
proceeding  for any remedy  available to the Trustee or exercising  any trust or
power  conferred on the Trustee.  However,  the Trustee may refuse to follow any
direction that conflicts with law or the Indenture, that may involve the Trustee
in  personal  liability,  or that the  Trustee  determines  in good faith may be
unduly  prejudicial  to the rights of  Holders  of the Notes not  joining in the
giving of such  direction  and may take any other action it deems proper that is
not inconsistent  with any such direction  received from Holders of the Notes. A
Holder  may not pursue any remedy  with  respect to the  Indenture  or the Notes
unless: (i) the Holder gives the Trustee written notice of a continuing Event of
Default;  (ii) the Holders of at least 25% in aggregate  principal amount of the
outstanding  Notes make a written  request to the  Trustee to pursue the remedy;
(iii) such  Holder or Holders  offer and,  if  requested,  provide  the  Trustee
indemnity  satisfactory to the Trustee against any costs,  liability or expense;
(iv) the Trustee does not comply with the request  within 60 days after  receipt
of the request and the offer of  indemnity;  and (v) during such 60-day  period,
the  Holders  of at  least a  majority  in  aggregate  principal  amount  of the
outstanding  Notes do not give the Trustee a direction that is inconsistent with
the request. However, such limitations do not apply to the right of any Notes to
receive payment of the principal of, premium, if any, or interest on, such Notes
or to bring suit for the  enforcement  of any such payment,  on or after the due
date  expressed  in the Notes,  which  right  shall not be  impaired or affected
without the consent of the Holder. 


                                       46
<PAGE>


     The Indenture will require certain  officers of the Company to certify,  on
or before a date not more than four months  after the end of each  fiscal  year,
that to the best of such officers' knowledge,  the Company has fulfilled all its
obligations  under the  Indenture.  The Company will also be obligated to notify
the Trustee of any default or defaults in the  performance  of any  covenants or
agreements under the Indenture.

MODIFICATION AND WAIVER

     The  Indenture  provides  that the  Company  and the  Trustee  may amend or
supplement  the Indenture or the Notes  without  notice to or the consent of any
Holder:  (i) to cure any ambiguity,  defect,  or inconsistency in the Indenture;
provided that such  amendments  or  supplements  shall not adversely  affect the
interests of the Holders in any material respect;  (ii) to comply with the terms
in "Restriction on Mergers, Consolidations and Sales of Assets" described below;
(iii) to comply with any  requirements  of the Commission in connection with the
qualification  of the  Indenture  under  the  Trust  Indenture  Act of 1939,  as
amended;  (iv) to evidence and provide for the  acceptance of  appointment  with
respect to the Notes of a successor  Trustee;  (v) to provide for uncertificated
Notes and to make all appropriate changes for such purpose; and (vi) to make any
change that does not materially and adversely affect the rights of any Holder.

     The  Indenture  also  provides  that  modifications  and  amendments of the
Indenture  may be made by the Company  and the  Trustee  with the consent of the
Holders  of not less  than a  majority  in  aggregate  principal  amount  of the
outstanding  Notes;  provided,  however,  that no such modification or amendment
may, without the consent of each Holder affected thereby,  (i) change the stated
maturity of the principal of, or any  installment of interest on, any Note, (ii)
reduce the  principal  amount of, or premium,  if any, or interest on, any Note,
(iii) reduce the  above-stated  percentage of  outstanding  Notes the consent of
whose Holders is necessary to modify or amend the Indenture  with respect to the
Notes,  or  (iv)  reduce  the  percentage  or  aggregate   principal  amount  of
outstanding  Notes the  consent  of whose  Holders  is  necessary  for waiver of
compliance  with certain  provisions  of the  Indenture or for waiver of certain
defaults.  It shall not be  necessary  for the consent of the Holders to approve
the  particular  form of any proposed  amendment,  supplement or waiver,  but it
shall be sufficient if such consent  approves the  substance  thereof.  After an
amendment,  supplement,  or waiver becomes effective,  the Company shall give to
the  Holders  affected  thereby  a  notice  briefly  describing  the  amendment,
supplement,  or waiver. The Company will mail supplemental indentures to Holders
upon  request.  Any  failure of the Company to mail such  notice,  or any defect
therein,  shall not,  however,  in any way impair or affect the  validity of any
such supplemental indenture or waiver.

RESTRICTION ON MERGERS, CONSOLIDATIONS AND SALES OF ASSETS

     The Company may not consolidate  with,  merge with or into, or transfer all
or substantially  all of its assets (as an entirety or substantially an entirety
in one transaction or a series of related  transactions),  to any Person unless:
(i) the Company shall be the continuing Person, or the Person (if other than the
Company) formed by such  consolidation or into which the Company is merged or to
which  properties and assets of the Company are  transferred  shall be a solvent
corporation  organized  and existing  under the laws of the United States or any
State thereof or the District of Columbia and shall expressly  assume in writing
all the  obligations  of the  Company  under the Notes and the  Indenture;  (ii)
immediately after giving effect to such transaction no Event of Default or event

series,  on the 123rd day after the deposit referred to below has been made, and
the provisions of the Indenture shall no longer be in effect with respect to the
Notes of such series (except for, among other  matters,  certain  obligations to
register  the transfer or exchange of the Notes,  to replace  stolen,  lost,  or
mutilated Notes, to maintain paying agencies,  and to hold monies for payment in
trust) if, among other things,  (A) the Company has  irrevocably  deposited with

payment of interest and principal in respect  thereof,  in accordance with their
terms  will  provide  money in an amount  sufficient  to pay the  principal  of,
premium,  if any, and accrued interest on the Notes of such series on the Stated
Maturity  thereof  or  earlier  redemption   (irrevocably   provided  for  under

its option  under  this  "Defeasance"  provision  and will be subject to federal
income tax on the same  amount  and in the same  manner and at the same times as
would have been the case if such  deposit,  defeasance,  and  discharge  had not
occurred, which Opinion of Counsel must be based upon (and accompanied by a copy
of) a ruling of the Internal Revenue Service to the same effect unless there has
been a  change  in  applicable  federal  income  tax law  after  the date of the
Indenture such that a ruling is no longer  required or (y) a ruling  directed to
the Trustee received from the Internal Revenue Service to the same effect as the
aforementioned  Opinion of Counsel  and (ii) an Opinion of Counsel to the effect
that the  creation  of the  defeasance  trust does not  violate  the  Investment
Company Act of 1940 and after the passage of 123 days following the deposit, the
trust fund will not be subject to the effect of section 547 of the United States
Bankruptcy  Code or section  15 of the New York  Debtor and  Creditor  Law,  (C)
immediately  after giving effect to such deposit on a pro forma basis,  no Event
of  Default,  or event  that after the giving of notice or lapse of time or both
would become an Event of Default,  shall have occurred and be continuing  (other
than a Default or Event of Default  resulting  from the borrowing of funds to be
applied to such deposit) on the date of such deposit or during the period ending
on the  123rd day after the date of such  deposit,  and such  deposit  shall not
result in a breach or violation  of, or  constitute a default  under,  any other
agreement or  instrument to which the Company is a party or by which the Company
is bound,  (D) the Company is not prohibited  from making payments in respect of
the  Notes of such  series  by the  subordination  provisions  contained  in the
Indenture  and (E) if at such  time the  Notes of such  series  are  listed on a
national  securities  exchange,  the  Company  has  delivered  to the Trustee an
Opinion  of  Counsel to the  effect  that the Notes of such  series  will not be
delisted as a result of such deposit, defeasance, and discharge.


Defeasance of Certain Covenants and Certain Events of Default

     The Indenture further provides that the provisions of the Indenture will no
longer be in effect with respect to the covenants  described in this  Prospectus
under "Covenants" and clause (iv) under "Events of Default" with respect to such
covenants and clauses  (iii) and (v) under  "Events of Default"  shall be deemed
not to be Events of Default with respect to the Notes of any series, upon, among
other  things,  the deposit  with the  Trustee,  in trust,  of money and/or U.S.
government  obligations through the payment of interest and principal in respect
thereof  in  accordance  with  their  terms  will  provide  money  in an  amount
sufficient to pay the principal of, premium, if any, and accrued interest on the
Notes of such  series,  on the Stated  Maturity  thereof  or earlier  redemption
(irrevocably provided for under agreements  satisfactory to the Trustee), as the
case may be, in accordance with the terms of the Indenture and the Notes of such
series,  the satisfaction of the provisions  described in clauses (B)(ii),  (C),
(D), and (E) of the  preceding  paragraph and the delivery by the Company to the
Trustee of an Opinion of Counsel to the effect  that,  among other  things,  the
holders of the Notes of such series will not recognize income, 


                                       48
<PAGE>

gain,  or loss for federal  income tax  purposes as a result of such deposit and
defeasance of the covenants and Events of Default and will be subject to federal
income tax on the same  amount  and in the same  manner and at the same times as
would have been the case if such deposit and defeasance had not occurred.


Defeasance and Certain Other Events of Default

     If the  Company  exercises  its  option  to omit  compliance  with  certain
covenants  and  provisions  of the  Indenture  with  respect to the Notes of any
series as described in the immediately preceding paragraph and the Notes of such
series are declared  due and payable  because of the  occurrence  of an Event of
Default that  remains  applicable,  the amount of money  and/or U.S.  Government
Obligations on deposit with the Trustee will be sufficient to pay amounts due on
the Notes of such series at the time of their  Stated  Maturity,  but may not be
sufficient  to pay  amounts  due on the Notes of such  series at the time of the
acceleration  resulting from such Event of Default.  However,  the Company shall
remain liable for such payments.

transactions in the over-the-counter market, in negotiated transactions, through
the  writing  of options on the New Notes or a  combination  of such  methods of
resale,  at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or negotiated  prices. Any such resale may be made
directly  to  purchasers  or to or through  brokers or dealers  who may  receive
compensation   in  the  form  of  commissions  or  concessions   from  any  such
broker-dealer  and/or the  purchasers of any such New Notes.  Any  broker-dealer
that resells New Notes that were received by it for its own account  pursuant to
the Exchange Offer and any broker or dealer that  participates in a distribution
of such New Notes may be deemed to be an "underwriter" within the meaning of the
Securities  Act  and  any  profit  on any  such  resale  of New  Notes  and  any
commissions  or  concessions  received  by any such  persons may be deemed to be
underwriting  compensation  under the Securities  Act. The Letter of Transmittal
states  that  by  acknowledging  that  it  will  deliver  and  by  delivering  a
prospectus,  a  broker-dealer  will  not  be  deemed  to  admit  that  it  is an
"underwriter" within the meaning of the Securities Act.

     For a period  of 90 days  after  the  Expiration  Date,  the  Company  will
promptly  send  additional  copies  of  this  Prospectus  and any  amendment  or
supplement to this Prospectus to any broker-dealer  that requests such documents
in the Letter of Transmittal.

     The Company has agreed in the  Registration  Rights  Agreement to indemnify
each  broker-dealer  reselling New Notes pursuant to this Prospectus,  and their
officers,  directors and controlling  persons,  against  certain  liabilities in
connection with the offer and sale of the New Notes, including liabilities under
the Securities Act, or to contribute to payments that such broker-dealers may be
required to make in respect thereof.

     The Company does not intend to list the Notes on any  securities  exchange.
The  Company  has been  advised by the Initial  Purchasers  that they  currently
intend  to make a  market  in the  Notes as  permitted  by  applicable  laws and
regulations. The Initial Purchasers are not obligated, however, to make a market
in the Notes and any such  market-making  may be discontinued at any time at the
sole  discretion  of the Initial  Purchasers.  Accordingly,  no assurance can be
given as to the liquidity of, or trading market for, the Notes.


                                 LEGAL MATTERS

     The  legality of the New Notes  offered  hereby will be passed upon for the
Company by Davis Polk & Wardwell, New York, New York.

                                     PART II


ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Under the  Company's  By-Laws,  and in  accordance  with Section 145 of the
Delaware General Corporation Law ("GCL"), the Company shall indemnify any person
who was or is a party or is  threatened  to be made a party  to any  threatened,
pending or  completed  action,  suit or  proceeding,  whether  civil,  criminal,
administrative  or  investigative  (other  than any  action or suit by or in the
right of the  Company to procure a judgment in its favor,  which is  hereinafter
referred to as a "derivative  action") by reason of the fact that such person is
or was a director,  officer or employee of the Company,  or is or was serving in
such  capacity or as an agent at the request of the Company for another  entity,
to the full extent authorized by Delaware law, against expenses (including,  but
not limited to,  attorneys'  fees),  judgments,  fines and amounts  actually and
reasonably incurred in connection with the defense or settlement of such action,
suit or proceeding if such person acted in good faith and in a manner the person
reasonably  believed  to be in or not  opposed  to  the  best  interests  of the
Company,  and,  with  respect  to any  criminal  action  or  proceeding,  had no
reasonable cause to believe was unlawful. Agents of the Company may be similarly
indemnified, at the discretion of the Board of Directors.

     Under  Section 145 of the GCL, a similar  standard of care is applicable in
the case of  derivative  actions,  except that  indemnification  only extends to
expenses (including  attorneys' fees) incurred in connection with the defense or
settlement of such an action and then, where the person is adjudged to be liable
to the  Company,  only if and to the extent  that the Court of  Chancery  of the
State of Delaware or the court in which such action was brought  determines that
such person is fairly and  reasonably  entitled to such  indemnity  and only for
such expenses as the court shall deem proper.

     Pursuant to Company's  By-Laws, a person eligible for  indemnification  may
have the expenses incurred in connection with any matter described above paid in
advance of a final disposition by the Company.  However, such advances will only
be made upon the delivery of an undertaking  by or on behalf of the  indemnified
person to repay all amounts so advanced if it is ultimately determined that such
person is not entitled to indemnification.

     In  addition,  under the  Company's  By-Laws,  the Company may purchase and
maintain  insurance  on behalf of any person who is or was a director,  officer,
employee or agent of the Company or of another corporation against any liability
asserted against and incurred by such person in such capacity, or arising out of
the person's  status as such whether or not the Company  would have the power or
the  obligation  to  indemnify  such person  against  such  liability  under the
provisions of the Company's By-Laws.

ITEM 22. UNDERTAKINGS

     The  undersigned   registrant  hereby  undertakes  that,  for  purposes  of
determining  any liability  under the Securities Act of 1933, each filing of the
registrant's  annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable,  each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the  registration  statement shall be
deemed to be a new  registration  statement  relating to the securities  offered
therein,  and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors,  officers and controlling  persons of the
registrant pursuant to the foregoing  provisions,  or otherwise,  the registrant
has been advised that in the opinion of the Securities  and Exchange  Commission
such  indemnification  is against  public policy as expressed in the Act and is,
therefore,  unenforceable. In the event that a claim for indemnification against
such liabilities  (other than the payment by the registrant of expenses incurred
or paid by a director,  officer or  controlling  person of the registrant in the
successful  defense of any  action,  suit or  proceeding)  is  asserted  by such
director,  officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

     The  undersigned  registrant  hereby  undertakes to respond to requests for
information  that is incorporated  by reference into the Prospectus  pursuant to
Items 4, 10(b), 11 or 13 of Form S-4, within one business day of receipt of such
request,  and to send the  incorporated  documents  by first class mail or other
equally prompt means.  This includes  information  contained in documents  filed
subsequent to the effective date of the Registration  Statement through the date
of responding to the request.

     The  undersigned  registrant  hereby  undertakes  to  supply  by means of a
post-effective  amendment  all  information  concerning a  transaction,  and the
company  being  acquired  involved  therein,  that  was not the  subject  of and
included in the registration statement when it became effective.

related  registration   statement  filed  pursuant  to  Rule  462(b)  under  the
Securities Act of 1933, and to file the same with all exhibits thereto, with the
Securities and Exchange  Commission,  granting unto said  attorneys-in-fact  and

the records of the Trustee as hereinafter provided.

          Each  Global   Security  shall   represent  such  of  the  outstanding
Securities  as shall be specified  therein and each shall  provide that it shall
represent the aggregate principal amount of outstanding  Securities from time to
time endorsed  thereon and that the aggregate  principal  amount of  outstanding
Securities represented thereby may from time to time be reduced or increased, as
appropriate,  to reflect  exchanges,  redemptions  and  transfers  of  interests
therein  in  accordance  with the  terms of this  Indenture.  Any  change in the
aggregate  principal  amount of a Global  Security  to reflect the amount of any
increase  or  decrease  in  the  principal  amount  of  outstanding   Securities
represented  thereby shall be made by the Trustee in accordance  with reasonable
instructions  given by the Holder  thereof as required by Section 2.6 hereof and
shall be conclusively reflected on the books and records of the Trustee.

          Upon the issuance of the Global Security to DTC, DTC shall credit,  on
its internal  book-entry  registration  and transfer system,  its  Participant's
accounts with the respective

be  limited  to  Participants,  including  Euroclear  and  Cedel,  and  indirect
Participants.

          The Participants shall not have any rights either under this Indenture
or under any Global  Security with respect to such Global Security held on their
behalf by DTC, and DTC may be treated by the Company,  the Trustee and any agent
of the Company or the Trustee as the absolute owner of such Global  Security for
the  purpose of  receiving  payment of or on  account of the  principal  of and,
subject to the provisions of this Indenture,  interest and Additional  Interest,
if any, on the Global Securities and for all other purposes. Notwithstanding the
foregoing, nothing herein shall prevent the Company, the Trustee or any agent of
the Company or the  Trustee  from  giving  effect to any written  certification,
proxy or other authorization  furnished by DTC or impair, as between DTC and its
Participants, the operation of customary practices of DTC governing the exercise
of the rights of an owner of a beneficial interest in any Global Security.

          The provisions of the "Operating  Procedures of the Euroclear  System"
and "Terms and Conditions Governing Use of Euroclear" and the "General Terms and
Conditions  of Cedel Bank" and "Customer  Handbook" of Cedel,  as in effect from
time to time,  shall be  applicable  to  interests  in the  Regulation  S Global
Security that are held by the Participants through Euroclear or Cedel.

          (b) Physical  Securities.  All Securities  will initially be issued in
the form of Global Securities pursuant to Section 2.1(a). If Physical Securities
are issued in accordance  with Section  2.6(a),  the Physical  Securities  which
represent Notes and the Physical Securities which represent  Debentures shall be
issued  initially  substantially  in the form of Exhibit A and Exhibit B hereto,
respectively,  in  certificated  form  and  issued  in the  names  of  the  then
beneficial holders thereof (or their nominees), duly executed by the Company and
authenticated by the Trustee as hereinafter provided.

          (c) Securities.  The provisions of the form of Securities contained in
Exhibit A and Exhibit B hereto are incorporated  herein by reference.  The Notes
and the Trustee's  Certificates of Authentication  shall be substantially in the
form of  Exhibit A hereto.  The  Debentures  and the  Trustee's  Certificate  of

and provided to the Trustee in writing by the Company. The Company shall approve
the form of the Securities  and any notation,  legend or endorsement on them. If
required,  the Securities may bear the  appropriate  legend  regarding  original
issue discount for federal income tax purposes. Each Security shall be dated the
date of its authentication. The terms and provisions contained in the Securities
shall constitute, and are hereby expressly made, a part of this Indenture.

          SECTION 2.2      Execution and Authentication.
                           -----------------------------

          Two Officers of the Company shall sign the  Securities for the Company
by manual or facsimile signature.

          If an Officer  whose  signature  is on a Security no longer holds that
office at the time the Trustee authenticates the Security, the Security shall be
valid nevertheless.

          A Security  shall not be valid until an  authorized  signatory  of the
Trustee manually signs the certificate of  authentication  on the Security.  The
signature shall be conclusive  evidence that the Security has been authenticated
under this Indenture.

          The Trustee shall  authenticate  (i) Initial  Securities  for original
issue from time to time, (ii) Private Exchange  Securities from time to time for
original issue or in exchange for a like principal amount of Initial  Securities
and (iii)  Unrestricted  Securities  from time to time for original  issue or in
exchange for a like principal amount of Initial Securities,  in each case upon a
written order signed by an Officer of the Company. The order shall be based upon
a Board  Resolution of the Company and shall specify the amount of Securities to
be authenticated and the date on which the original issue of Securities is to be
authenticated.   The  order   shall   also   provide   instructions   concerning
registration,  legends,  if any,  pursuant to Section  2.6(f),  amounts for each
Holder and  delivery.  If Notes or  Debentures  are to be issued  after the date
hereof,  then the Company shall deliver Global Securities in the Form of Exhibit
A  or  Exhibit  B  hereto,   respectively,   together  with  an  order  for  the
authentication and delivery by the Trustee of such Global Security or Securities
and the Trustee shall,  in accordance  with this Section 2.2,  authenticate  and
deliver such Global Security or Securities.  The Securities shall be issued only
in registered form,  without coupons and only in denominations of $1,000 and any
integral multiple thereof.

          SECTION 2.3      Registrar and Paying Agent.
                           --------------------------

          The Company shall maintain an office or agency where Securities may be
presented  for  registration  of transfer or for exchange  ("Registrar")  and an
office or agency where Securities may be presented for payment ("Paying Agent").
The Company may have one or more  additional  paying  agents.  The term  "Paying
Agent" includes any additional paying agent.

          The Company shall enter into an appropriate  agency agreement with any
Agent  not a  party  to  this  Indenture.  The  agreement  shall  implement  the
provisions of this Indenture  that relate to such Agent and shall,  if required,
incorporate  the  provisions of the TIA. The Company shall notify the Trustee of
the name and  address of any such  Agent.  If the  Company  fails to  maintain a
Registrar or Paying  Agent,  the Trustee shall act as such and shall be entitled
to appropriate compensation in accordance with the provisions of Section 7.7.

          The Company  initially  appoints the Trustee as  Registrar  and Paying
Agent.  The Company  shall give written  notice to the Trustee in the event that
the Company decides to act as Registrar.

          SECTION 2.4      Paying Agent To Hold Money in Trust.
                           -----------------------------------

          The Company  shall  require  each Paying  Agent to agree in writing to
hold in trust for the benefit of  Securityholders  or the Trustee all money held
by the  Paying  Agent  for  the  payment  of  principal  of or  interest  on the
Securities  (whether  such money has been paid to it by the Company or any other
obligor on the  Securities),  and the  Company  and the Paying  Agent shall each
notify the Trustee of any  default by the  Company (or any other  obligor on the
Securities)  in making any such  payment.  The Company at any time may require a
Paying  Agent to pay all money held by it to the  Trustee  and  account  for any
funds  disbursed and the Trustee may at any time during the  continuance  of any
payment  default,  upon written  request to a Paying Agent,  require such Paying
Agent to pay all money held by it to the  Trustee  and to account  for any funds
disbursed.  Upon  making  such  payment  the Paying  Agent shall have no further
liability for the money delivered to the Trustee.

          SECTION 2.5      Securityholder Lists.
                           ---------------------

          The  Trustee  shall  preserve  in as  current a form as is  reasonably
practicable  the most recent list  available to it of the names and addresses of
Securityholders.  If the Trustee is


<PAGE>

                                      -30-

not the  Registrar,  the  Company  shall  furnish  to the  Trustee at least five
Business Days before each  Interest  Payment Date and at such other times as the
Trustee  may  request  in writing a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of Securityholders.

          SECTION 2.6      Transfer and Exchange.
                           ----------------------

          (a) Transfer and Exchange of Global Securities. Transfer of the Global
Securities shall be by delivery.  Global Securities may not be transferred as or
exchanged for Physical Securities except (i) if DTC notifies the Company that it
is  unwilling  or unable to continue to act as  depositary  with  respect to the
Global  Securities  or  ceases  to be a  clearing  agency  registered  under the
Exchange  Act and,  in either  case,  a  successor  depositary  registered  as a
clearing  agency under the Exchange Act is not  appointed by the Company  within
120 days, (ii) at any time if the Company in its sole discretion determines that
the  Global  Securities  (in whole  but not in part)  should  be  exchanged  for
Physical  Securities  or  (iii)  if the  owner  of an  interest  in  the  Global
Securities  requests  such  Physical  Securities,  following an Event of Default
under this Indenture, in a writing delivered through DTC to the Trustee.

          Upon the  occurrence  of any of the events  specified  in the previous
paragraph,  Physical  Securities  shall be  issued  in such  names as DTC  shall
instruct the Trustee and the Trustee shall cause the aggregate  principal amount
of the applicable  Global  Security to be reduced  accordingly and direct DTC to
make a  corresponding  reduction in its  book-entry  system.  The Company  shall
execute and the Trustee  shall  authenticate  and cause to be  delivered  to the
Person  designated in such  instructions a Physical  Security in the appropriate
principal amount and of the appropriate  Series.  The Trustee shall deliver such
Physical  Securities  to the  Persons  in whose  names  such  Securities  are so
registered.  Physical  Securities  issued  in  exchange  for an  Initial  Global
Security  pursuant to this Section  2.6(a) shall bear the  Securities Act Legend
and shall be subject to all restrictions on transfer contained  therein.  Global
Securities  may also be exchanged or replaced,  in whole or in part, as provided
in Sections 2.7 and 2.8. Every Security  authenticated and delivered in exchange
for,  or in lieu of, a Global  Security  or any  portion  thereof,  pursuant  to
Section 2.7 or 2.8,  shall be  authenticated  and  delivered in the form of, and
shall be, a Global Security.  A Global Security may not be exchanged for another
Security other than as provided in this Section 2.6(a).

          (b)  Transfer and  Exchange of  Interests  in Global  Securities.  The
transfer  and  exchange  of  interests  in Global  Securities  shall be effected
through  DTC,  in  accordance  with this  Indenture  and the  procedures  of DTC
therefor.   Interests  in  Initial  Global   Securities   shall  be  subject  to
restrictions  on  transfer  comparable  to those set forth  herein to the extent
required  by the  Securities  Act.  The  Trustee  shall  have no  obligation  to
ascertain DTC's compliance with any such restrictions on transfer.  Transfers of
interests in Global  Securities shall also require  compliance with subparagraph
(i)  below,  as  well as one or more of the  other  following  subparagraphs  as
applicable:

                    (i) All  Transfers  and  Exchanges  of  Interests  in Global
         Securities. In connection with all transfers and exchanges of interests
         in Global  Securities  (other than  transfers  of interests in a Global
         Security  to  Persons  who  take  delivery  thereof  in the  form of an
         interest in the same Global Security),  the transferor of such interest
         must deliver to the Registrar (1) instructions given in accordance with
         the Applicable Procedures from a Participant or an indirect Participant
         directing  DTC to credit or cause to be  credited  an  interest  in the
         specified Global Security of the specified Series in an amount equal to
         the interest to be transferred or exchanged,  (2) a written order given
         in accordance  with the Applicable  Procedures  containing  information
         regarding the Participant account to be credited with such increase and
         (3)  instructions  given by the  Holder of the Global  Security  of the
         specified  Series to effect  the  transfer  referred  to in (1) and (2)
         above.

                   (ii)  Transfer  of  Interests  in  the  Same  Initial  Global
         Security.  Interests in any Initial Global  Security may be transferred
         to Persons who take delivery  thereof in the form of an interest in the
         same Initial Global  Security of the same Series in accordance with the
         transfer restrictions set forth in Section 2.6(f) hereof.

                  (iii)   Transfer  of  Interests  to  Another   Initial  Global
         Security.  Interests in any Initial Global  Security may be transferred
         to Persons  who take  delivery  thereof in the form of an  interest  in
         another  Initial  Global  Security of the same series if the  Registrar
         receives the following:

                           (A) if the transferee  will take delivery in the form
                  of an interest in a 144A Global  Security of the same  Series,
                  then the transferor  must deliver a cer-


<PAGE>

                                      -32-

                  tificate  in the  form of  Exhibit  C  hereto,  including  the
                  certifications in item 1 thereof; or

                           (B) if the transferee  will take delivery in the form
                  of an interest in a Regulation  S Global  Security of the same
                  Series,  then the transferor must deliver a certificate in the
                  form of Exhibit C hereto, including the certifications in item
                  2 thereof.

                   (iv)  Transfer and  Exchange of  Interests in Initial  Global
         Security for Interests in an Unrestricted Global Security. Interests in
         any Initial Global  Security may be exchanged by the holder thereof for
         an interest in an  Unrestricted  Global  Security of the same Series or
         transferred  to a Person who takes  delivery  thereof in the form of an
         interest in an Unrestricted Global Security of the same Series if:

                           (A) such exchange or transfer is effected pursuant to
                  the Exchange  Registration  Statement in  accordance  with the
                  Registration Rights Agreement;

                           (B) any such  transfer  is  effected  pursuant to the
                  Shelf   Registration   Statement   in   accordance   with  the
                  Registration Rights Agreement; or

                           (C) the Registrar receives the following:

                                    (1) if the holder of such an  interest in an
                           Initial Global  Security  proposes to exchange it for
                           an interest in an Unrestricted Global Security of the
                           same Series,  a  certificate  from such Holder in the
                           form   of   Exhibit   D   hereto,    including    the
                           certifications in item 1(a) thereof;

                                    (2) if the holder of such an  interest in an
                           Initial Global Security  proposes to transfer it to a
                           Person who shall take delivery thereof in the form of
                           an interest in an Unrestricted Global Security of the
                           same Series,  a certificate  in the form of Exhibit C
                           hereto,   including  the   certification  in  item  4
                           thereof; and

                                    (3) in each  such  case  set  forth  in this
                           paragraph   (C),   an  Opinion  of  Counsel  in  form
                           reasonably acceptable to the Company and the Trustee,
                           to the effect  that such  exchange  or transfer is in
                           compliance  with the  Securities  


<PAGE>

                                      -33-

                           Act and, that the restrictions on transfer  contained
                           herein and in Section  2.6(f) hereof are not required
                           in order to maintain  compliance  with the Securities
                           Act.

         If any such  transfer is effected  pursuant to paragraph (B) above at a
         time when an Unrestricted Global Security of the appropriate Series has
         not yet been issued,  the Company  shall issue and,  upon receipt of an
         authentication  order in accordance with Section 2.2, the Trustee shall
         authenticate  one  or  more  Unrestricted   Global  Securities  of  the
         appropriate  Series  in an  aggregate  principal  amount  equal  to the
         principal   amount  of  interests  in  the  Initial   Global   Security
         transferred  pursuant to paragraph (B) above,  provided the Company has
         made  appropriate  arrangements  with DTC prior to  delivery of such an
         authentication order to the Trustee.

                    (v) Notation by the Trustee of Transfer of  Interests  Among
         Global  Securities.  Upon satisfaction of the requirements for transfer
         of  interests  in Global  Securities  of the same  Series  pursuant  to
         clauses  (iii) or (iv) above,  the Trustee  shall reduce or cause to be
         reduced the aggregate  principal amount of the relevant Global Security
         from which the interests are being  transferred,  and increase or cause
         to be increased the aggregate  principal  amount of the Global Security
         to which the  interests  are being  transferred,  in each case,  by the
         principal   amount  so  transferred   and  shall  direct  DTC  to  make
         corresponding  adjustments  in its  book-entry  system.  No transfer of
         interests  of a  Global  Security  shall  be  effected  until,  and any
         transferee  pursuant thereto shall succeed to the rights of a holder of
         such  interests   only  when,   the  Registrar  has  made   appropriate
         adjustments to the applicable  Global  Security in accordance with this
         paragraph.

          (c)  Transfer or Exchange of Physical  Securities  for  Interests in a
Global Security.

                    (i) If any Holder of Physical Securities required to contain
         the Securities Act Legend  proposes to exchange such  Securities for an
         interest in a Global Security, then, upon receipt by the Registrar of a
         certificate from such Holder in the form of Exhibit D hereto, including
         the  certifications  in  item  2  thereof  which  may be  submitted  by
         facsimile;


<PAGE>

                                      -34-

         the Trustee shall cancel the Physical Securities,  increase or cause to
         be  increased  the  aggregate  principal  amount  of,  the 144A  Global
         Security or the Regulation S Global Security of the same Series, as the
         case may be,  and direct DTC to make a  corresponding  increase  in its
         book-entry system.

                   (ii) A Holder of Physical  Securities required to contain the
         Securities  Act Legend may exchange such  Securities for an interest in
         an Unrestricted Global Security of the same Series only:

                           (A) if such exchange or transfer is effected pursuant
                  to the Exchange Registration  Statement in accordance with the
                  Registration Rights Agreement;

                           (B) any such  transfer  is  effected  pursuant to the
                  Shelf   Registration   Statement   in   accordance   with  the
                  Registration Rights Agreement;

                           (C) upon receipt by the  Registrar  of the  following
                  documentation (all of which may be submitted by facsimile):

                                    (1)  if  the   Holder   of   such   Physical
                           Securities  proposes to exchange such  Securities for
                           an interest in an Unrestricted Global Security of the
                           same Series,  a  certificate  from such Holder in the
                           form   of   Exhibit   D   hereto,    including    the
                           certifications in item 1(b) thereof;

                                    (2) an Opinion of Counsel in form reasonably
                           acceptable  to the  Company,  to the effect that such
                           exchange  or  transfer  is  in  compliance  with  the
                           Securities Act and that the  restrictions on transfer
                           contained herein and in Section 2.6(f) hereof are not
                           required  in order to  maintain  compliance  with the
                           Securities Act.

         If any such  transfer is effected  pursuant to paragraph (B) above at a
         time when an Unrestricted Global Security of the appropriate Series has
         not yet been issued,  the Company  shall issue and,  upon receipt of an
         authentication  order in accordance with Section 2.2, the Trustee shall
         authenticate  (i) one or more  Unrestricted  Global  Securities  of the
         appropriate  Series  in an  aggregate  principal  amount  equal  to the
         principal  amount  of  Physical  Securities   transferred  pursuant  to
         paragraph (B) above.

                    (i)  Transfer  of a Physical  Security  to Another  Physical
         Security.  Following  the  occurrence  of one  or  more  of the  events
         specified in Section 2.6(a), a Physical  Security may be transferred to
         Persons  who take  delivery  thereof  in the form of  another  Physical
         Security of the same Series if the Registrar receives the following:

                           (A) if the transfer is being effected pursuant to and
                  in accordance with Rule 144A, then the transferor must deliver
                  a certificate  in the form of Exhibit C hereto,  including the
                  certifications in item 3(a) thereof; or

                           (B) if the transfer is being effected pursuant to and
                  in  accordance  with  Regulation S, then the  transferor  must
                  deliver  a  certificate  in the  form  of  Exhibit  C  hereto,
                  including the certifications in item 3(b) thereof.

                   (ii)  Transfer and Exchange of Restricted  Physical  Security
         for Physical  Security  Which Does Not Bear the  Securities Act Legend.
         Following  the  occurrence  of one or more of the events  specified  in
         Section  2.6(a)  and  the  receipt  by  the  Trustee  of  an  Officers'
         Certificate  stating  that such  events  have  occurred,  a  Restricted
         Physical Security may be exchanged by the Holder thereof for a Physical
         Security  of the same  Series  or  transferred  to a Person  who  takes
         delivery thereof in the form of a Physical  Security of the same Series
         which does not bear the Securities Act Legend if:

                           (A) such exchange or transfer is effected pursuant to
                  the Exchange  Registration  Statement in  accordance  with the
                  Registration Rights Agreement;

                           (B) any such  transfer  is  effected  pursuant to the
                  Shelf   Registration   Statement   in   accordance   with  the
                  Registration Rights Agreement; or

                           (C) the Registrar  receives a  certificate  from such
                  Holder  in  the  form  of  Exhibit  D  hereto,  including  the
                  certifications  in item 1(c) thereof and an Opinion of Counsel
                  in form  reasonably  acceptable to the Company,  to the effect
                  that such  exchange  or  transfer  is in  compliance  with the
                  Securities  Act  and,  that  the   restrictions   on  transfer
                  contained


<PAGE>

                                      -36-

                  herein and in Section  2.6(f) hereof are not required in order
                  to maintain compliance with the Securities Act.

                  (iii)   Exchange  of  Physical   Securities.   When   Physical
         Securities are presented by a Holder to the Registrar with a request to
         register  the  exchange  of  such  Physical  Securities  for  an  equal
         principal amount of Physical Securities of the same Series but of other
         authorized  denominations,  the  Registrar  shall make the  exchange as
         requested  only if the Physical  Securities are endorsed or accompanied
         by a  written  instrument  of  transfer  in  form  satisfactory  to the
         Registrar  duly  executed  by  such  Holder  or by  his  attorney  duly
         authorized  in  writing  and shall be  issued  only in the name of such
         Holder or its nominee.  The Physical  Securities issued in exchange for
         Physical  Securities of the same Series shall bear the  Securities  Act
         Legend and shall be subject to all  restrictions on transfer  contained
         herein in each case to the same extent as the  Physical  Securities  so
         exchanged.

                   (iv)  Return  of  Physical  Securities.  In  the  event  of a
         transfer  pursuant to clauses (i) or (ii) above and the Holder  thereof
         has delivered  certificates  representing an aggregate principal amount
         of  Securities in excess of that to be  transferred,  the Company shall
         execute and the  Trustee  shall  authenticate  and make  available  for
         delivery to the Holder of such Security  without service charge,  a new
         Physical  Security or Securities  of the same Series of any  authorized
         denomination  requested by the Holder, in an aggregate principal amount
         equal to the portion of the Security not so transferred.

          (e) Exchange  Offer.  Upon the  occurrence  of the Exchange  Offer (as
defined  in  the   Registration   Rights   Agreement)  in  accordance  with  the
Registration  Rights Agreement,  the Company shall issue and, upon receipt of an
Officers'  Certificate  stating that the  Exchange  Registration  Statement  has
become effective and that the Exchange Offer has occurred and an  authentication
order in accordance with Section 2.2, the Trustee shall authenticate one or more
Unrestricted  Global  Securities  of  the  appropriate  Series  in an  aggregate
principal  amount equal to the principal  amount of the interests in the Initial
Global  Securities.  Concurrently  with the  issuance  of such  Securities,  the
Trustee shall cause the aggregate  principal  amount of the  applicable  Initial
Global Securities of the appropriate Series to be reduced accordingly and direct
DTC to make a corresponding reduction in its book-entry system.


<PAGE>

                                      -37-

          In the case that one or more of the events specified in Section 2.6(a)
have  occurred,  upon the occurrence of such Exchange  Offer,  the Company shall
issue and, upon receipt of an  authentication  order in accordance  with Section
2.2, the Trustee  shall  authenticate  Unrestricted  Physical  Securities of the
appropriate  Series in an  aggregate  principal  amount  equal to the  principal
amount of the Restricted  Physical Securities tendered for acceptance by persons
participating therein.

          (f) Legends.

          Each Initial  Global  Security  and, if  applicable,  each  Restricted
Physical  Security  shall bear the  legend  (the  "Securities  Act  Legend")  in
substantially the following form:

         THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE U.S.  SECURITIES ACT OF
         1933, AS AMENDED (THE "SECURITIES ACT"), AND,  ACCORDINGLY,  MAY NOT BE
         OFFERED OR SOLD  WITHIN THE UNITED  STATES OR TO, OR FOR THE ACCOUNT OR
         BENEFIT OF, U.S. PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE.
         BY ITS ACQUISITION  HEREOF,  THE HOLDER (1) REPRESENTS THAT (A) IT IS A
         "QUALIFIED  INSTITUTIONAL  BUYER"  (AS  DEFINED  IN RULE 144A UNDER THE
         SECURITIES  ACT), OR (B) IT IS NOT A U.S.  PERSON AND IS ACQUIRING THIS
         SECURITY IN AN OFFSHORE TRANSACTION, (2) AGREES THAT IT WILL NOT WITHIN
         TWO YEARS  AFTER  THE  ORIGINAL  ISSUANCE  OF THIS  SECURITY  RESELL OR
         OTHERWISE  TRANSFER THIS SECURITY  EXCEPT (A) TO AES OR ANY  SUBSIDIARY
         THEREOF,  (B)  INSIDE THE UNITED  STATES TO A  QUALIFIED  INSTITUTIONAL
         BUYER IN  COMPLIANCE  WITH RULE  144A  UNDER THE  SECURITIES  ACT,  (C)
         OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH
         RULE 904 UNDER THE  SECURITIES  ACT, (D) PURSUANT TO THE EXEMPTION FROM
         REGISTRATION  PROVIDED  BY  RULE  144  UNDER  THE  SECURITIES  ACT  (IF
         AVAILABLE) OR (E) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER
         THE  SECURITIES  ACT AND (3) AGREES THAT IT WILL DELIVER TO EACH PERSON
         TO WHOM THIS  SECURITY IS  TRANSFERRED  A NOTICE  SUBSTANTIALLY  TO THE
         EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY TRANSFER OF THIS SECURITY
         WITHIN TWO YEARS  AFTER THE  ORIGINAL  ISSUANCE  OF THE  SECURITY,  THE
         HOLDER MUST SUBMIT A  CERTIFICATE  WITH RESPECT TO SUCH TRANSFER TO THE
         TRUSTEE (A FORM OF WHICH MAY BE  OBTAINED  FROM THE  TRUSTEE);  AS USED
         HEREIN,  THE TERMS  "OFFSHORE  TRANSACTION,"  "UNITED STATES" AND "U.S.
         PERSON"  HAVE THE  MEANINGS  GIVEN TO THEM BY  REGULATION  S UNDER  THE
         SECURITIES  ACT.  THE  


<PAGE>

                                      -38-

         INDENTURE  CONTAINS  A  PROVISION  REQUIRING  THE  TRUSTEE TO REFUSE TO
         REGISTER  ANY TRANSFER OF THIS  SECURITY IN VIOLATION OF THE  FOREGOING
         RESTRICTIONS.

          (g) Global Security  Legend.  Each Global Security shall bear a legend
in substantially the following form:

                  "UNLESS  AND  UNTIL  IT IS  EXCHANGED  IN WHOLE OR IN PART FOR
         SECURITIES IN  DEFINITIVE  FORM,  THIS SECURITY MAY NOT BE  TRANSFERRED
         EXCEPT  AS A  WHOLE  BY  THE  DEPOSITORY  TRUST  COMPANY,  A  NEW  YORK
         CORPORATION ("DTC") TO A NOMINEE OF DTC, OR BY ANY SUCH NOMINEE OF DTC,
         OR BY DTC TO A  SUCCESSOR  DEPOSITORY  OR A NOMINEE  OF SUCH  SUCCESSOR
         DEPOSITORY.  UNLESS THIS  CERTIFICATE  IS  PRESENTED  BY AN  AUTHORIZED
         REPRESENTATIVE  OF DTC, TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF
         TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED
         IN THE NAME OF CEDE & CO.  OR SUCH  OTHER  NAME AS IS  REQUESTED  BY AN
         AUTHORIZED  REPRESENTATIVE  OF DTC (AND ANY  PAYMENT  HEREON IS MADE TO
         CEDE & CO. OR TO SUCH OTHER  ENTITY AS IS  REQUESTED  BY AN  AUTHORIZED
         REPRESENTATIVE  OF DTC).  ANY TRANSFER,  PLEDGE OR OTHER USE HEREOF FOR
         VALUE OR  OTHERWISE  BY OR TO ANY PERSON IS  WRONGFUL  INASMUCH  AS THE
         REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

         TRANSFERS  OF THIS GLOBAL  SECURITY  SHALL BE LIMITED TO  TRANSFERS  IN
         WHOLE,  BUT NOT IN PART,  TO  NOMINEES  OF CEDE & CO. OR TO A SUCCESSOR
         THEREOF OR SUCH  SUCCESSOR'S  NOMINEE AND TRANSFERS OF PORTIONS OF THIS
         GLOBAL  SECURITY SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE  WITH
         THE RESTRICTIONS SET FORTH IN SECTION 2.6 OF THE INDENTURE."

          (h) Cancellation and/or Adjustment of Global Securities.  At such time
as all interests in the Global  Securities  of a Series have been  exchanged for
Physical  Securities  of the same Series,  all Global  Securities of that Series
shall be returned to or retained and canceled by the Trustee in accordance  with
Section 2.9 hereof. At any time prior to such cancellation, if any interest in a
Global  Security is exchanged for an interest in another Global  Security or for
Physical  Securities  of the same Series,  the  principal  amount of  Securities
represented by such Global  Security shall be reduced  accordingly  and all such
changes to such Global  Security  shall be reflected on the books and records of
the Trustee, by the Trustee to reflect such reduction.

          (i) General Provisions Relating to All Transfers and Exchanges.

                    (i) To permit registrations of transfers and exchanges,  the
         Company  shall  execute  and  the  Trustee  shall  authenticate  Global
         Securities of the appropriate  Series and,  following the occurrence of
         one or  more  of the  events  specified  in  Section  2.6(a),  Physical
         Securities of the appropriate  Series upon a written order signed by an
         Officer of the Company or at the Registrar's request.

                   (ii) No  service  charge  shall be made to a  Holder  for any
         registration  of  transfer  or  exchange,  but the  Company may require
         payment  of a sum  sufficient  to cover  any stamp or  transfer  tax or
         similar governmental charge payable in connection therewith (other than
         any such stamp or transfer taxes or similar governmental charge payable
         upon exchange or transfer  pursuant to Sections 2.8, 3.8, 4.11 and 4.15
         hereof).

                  (iii) All Global  Securities  and Physical  Securities  issued
         upon any  registration of transfer or exchange of Global  Securities or
         Physical  Securities  shall be the valid  obligations  of the  Company,
         evidencing  the same debt, and entitled to the same benefits under this
         Indenture,  as the Global Securities or Physical Securities surrendered
         upon such registration of transfer or exchange.

                   (iv) The  Company  shall not be  required  (A) to  issue,  to
         register  the  transfer  of or to exchange  Securities  during a period
         beginning  at the  opening of  business  15 days  before the day of the
         mailing of the notice of  redemption  of  Securities  and ending at the
         close of business such  mailing,  (B) to register the transfer of or to
         exchange any Security so selected for  redemption  in whole or in part,
         except the unredeemed portion of any Security being redeemed in part or
         (C) to register  the  transfer  of or to exchange a Security  between a
         record date and the next succeeding Interest Payment Date.

                    (v)  Prior  to due  presentment  for the  registration  of a
         transfer of any  Security,  the Trustee,  any Agent and the Company may
         deem and treat the Person in whose name any Security is  registered  as
         the  absolute  owner of such  Security  for the  purpose  of  receiving
         payment of  principal of and  interest on such  Securities  and for all
         other purposes, and none of the Trustee, any Agent or the Company shall
         be affected by notice to the contrary.

                                      -40-

                   (vi) The Trustee shall have no obligation or duty to monitor,
         determine or inquire as to compliance with any restrictions on transfer
         imposed under this  Indenture or under  applicable  law with respect to
         any transfer of any interest in any Security  (including  any transfers
         between or among  Participants or beneficial owners of interests in any
         Global  Security) other than to require  delivery of such  certificates
         and other  documentation or evidence as are expressly  required by, and
         to  do so if  and  when  expressly  required  by  the  terms  of,  this
         Indenture,  and to examine the same to determine substantial compliance
         as to form with the express requirements hereof.

          SECTION 2.7      Replacement Securities.
                           -----------------------

          If any mutilated  Security is surrendered to the Trustee,  the Company
shall  execute  and the  Trustee  shall  authenticate  and  deliver in  exchange
therefor a new Security of like tenor, principal amount and Series and bearing a
number not contemporaneously outstanding.

          If  there  shall be  delivered  to the  Company  and the  Trustee  (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
and (ii) such  security or  indemnity as may be  reasonably  required by them to
save each of them and any agent of either of them harmless, then, in the absence
of notice to the Company or the Trustee that such  Security has been acquired by
a bona fide  purchaser,  the  Company  shall  execute  and upon its  request the
Trustee shall authenticate and deliver,  in lieu of any such destroyed,  lost or
stolen  Security,  a new Security of like tenor and principal amount and Series,
having endorsed thereon and bearing a number not contemporaneously outstanding.

          Upon the issuance of any new Security under this Section,  the Company
may  require  the  payment  of a sum  sufficient  to  cover  any  tax  or  other
governmental  charge  that may be  imposed  in  relation  thereto  and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

          Every new  Security  issued  pursuant  to this  Section in lieu of any
destroyed,  lost or stolen  Security  shall  constitute  an original  additional
contractual  obligation  of the Company  whether or not the  destroyed,  lost or
stolen  Security  shall be at any  time  enforceable  by  anyone,  and  shall be
entitled to all the benefits of this Indenture equally and proportionately  with
any and all other Securities of the same Series duly issued hereunder.


<PAGE>

                                      -41-

          The  provisions of this Section are  exclusive and shall  preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities.

          SECTION 2.8      Temporary Securities.
                           ---------------------

          Pending the  preparation  of  definitive  Securities,  the Company may
execute and, upon Company  Order,  the Trustee shall  authenticate  and deliver,
temporary Securities which are printed,  lithographed typewritten,  mimeographed
or otherwise  produced,  in any authorized  denomination,  substantially  of the
tenor of the  definitive  Securities in lieu of which they are issued,  and with
such appropriate  insertions,  omissions,  substitutions and other variations as
the officers  executing such  Securities  may  determine,  as evidenced by their
execution of such Securities.

          If temporary  Securities are issued, the Company will cause definitive
Securities to be prepared without  unreasonable  delay. After the preparation of
definitive  Securities,  the  temporary  Securities  shall be  exchangeable  for
definitive  Securities  of the  same  Series  upon  surrender  of the  temporary
Securities at any office or agency of the Company designated pursuant to Section
10.2,  without charge to the Holder.  Upon surrender for cancellation of any one
or more  temporary  Securities  the Company  shall execute and the Trustee shall
authenticate  and make  available  for  delivery  in  exchange  therefor  a like
principal amount of definitive  Securities of authorized  denominations and like
tenor and Series.  Until so  exchanged  the  temporary  Securities  shall in all
respects be entitled to the same  benefits  under this  Indenture as  definitive
Securities of the same Series.

          SECTION 2.9      Cancellation.
                           -------------

          All Securities surrendered for payment,  redemption or registration of
transfer or exchange shall, if surrendered to any Person other than the Trustee,
be  delivered  to the Trustee and shall be promptly  canceled by it. The Company
may at  any  time  deliver  to  the  Trustee  for  cancellation  any  Securities
previously  authenticated  and  delivered  hereunder  which the Company may have
acquired in any manner  whatsoever,  and all  Securities  so delivered  shall be
promptly  canceled by the Trustee.  No Securities shall be authenticated in lieu
of or in exchange  for any  Securities  canceled  as  provided in this  Section,
except as expressly permitted by this Indenture. All canceled Securities held by
the Trustee shall be returned to the Company.

          SECTION 2.10     Defaulted Interest.
                           -------------------

          Any interest on any Security  which is payable,  but is not punctually
paid  or  duly  provided  for,  on any  Interest  Payment  Date  (herein  called
"Defaulted  Interest")  shall forthwith cease to be payable to the Holder on the
relevant  Regular  Record  Date by virtue of having been such  Holder,  and such
Defaulted Interest may be paid by the Company,  at its election in each case, as
provided in clause (1) or (2) below:

                    (1) The Company may elect to make  payment of any  Defaulted
         Interest  to the  Persons  in whose  names  the  Securities  (or  their
         respective  Predecessor  Securities)  are  registered  at the  close of
         business on a Special  Record  Date for the  payment of such  Defaulted
         Interest,  which shall be fixed in the  following  manner.  The Company
         shall notify the Trustee in writing of the amount of Defaulted Interest
         proposed  to be paid  on each  Security  and the  date of the  proposed
         payment,  and at the  same  time the  Company  shall  deposit  with the
         Trustee an amount of money equal to the aggregate amount proposed to be
         paid in respect of such Defaulted  Interest or shall make  arrangements
         satisfactory  to the Trustee for such deposit  prior to the date of the
         proposed payment, such money when deposited to be held in trust for the
         benefit of the Persons  entitled to such Defaulted  Interest as in this
         clause provided.  Thereupon the Company shall fix a Special Record Date
         for the payment of such Defaulted Interest which shall be not more than
         15 days prior to the date of the proposed  payment.  The Company  shall
         promptly  notify the  Trustee of such  Special  Record Date and, in the
         name and at the expense of the Company,  the Trustee shall cause notice
         of the  proposed  payment of such  Defaulted  Interest  and the Special
         Record Date therefor to be mailed, first-class postage prepaid, to each
         Holder at his address as it appears in the Security Register,  not less
         than five  Business Days prior to such Special  Record Date.  Notice of
         the proposed payment of such Defaulted  Interest and the Special Record
         Date therefor having been so mailed,  such Defaulted  Interest shall be
         paid not later than the fifteenth day after such Special Record Date to
         the  Persons  in  whose  names  the  Securities  (or  their  respective
         Predecessor Securities) are registered at the close of business on such
         Special Record Date.

                           (2) The  Company  may make  payment of any  Defaulted
         Interest  in  any  other  lawful  manner  not  inconsistent   with  the
         requirements of any securities  exchange on 


<PAGE>

                                      -43-

         which the  Securities  may be  listed,  and upon such  notice as may be
         required by such exchange, if, after notice given by the Company to the
         Trustee of the proposed payment pursuant to this clause, such manner of
         payments shall be deemed practicable by the Trustee.

         SECTION 2.11      CUSIP or CINS Number.
                           ---------------------

         The  Company  in  issuing  the  Securities  may use a "CUSIP" or "CINS"
number,  and if so,  such CUSIP or CINS  number  shall be included in notices of
redemption  or exchange as a  convenience  to  Holders;  provided  that any such
notice  may  state  that no  representation  is made  as to the  correctness  or
accuracy of the CUSIP or CINS number printed in the notice or on the Securities,
and that reliance may be placed only on the other identification numbers printed
on the Securities. The Company will promptly notify the Trustee of any change in
the CUSIP or CINS number.

         SECTION 2.12      Payments of Interest.
                           ---------------------

         (a) The Holder of a Physical  Security  at the close of business on the
Regular Record Date with respect to any Interest  Payment Date shall be entitled
to  receive  the  interest  and  Additional  Interest,  if any,  payable on such
Interest Payment Date  notwithstanding any transfer or exchange of such Physical
Security  subsequent  to the  regular  record  date and  prior to such  Interest
Payment  Date,  except if and to the extent  the  Company  shall  default in the
payment of the  interest or  Additional  Interest due on such  Interest  Payment
Date, in which case such  Defaulted  Interest and Additional  Interest,  if any,
shall be paid in accordance with Section 2.10; provided that, in the event of an
exchange of a Physical Security for a beneficial interest in any Global Security
subsequent to a Regular  Record Date or any Special  Record Date and prior to or

name such  Physical  Security was  registered  on such record date.  Payments of
interest  on the  Global  Securities  will be made to the  Holder of the  Global
Security  on each  Interest  Payment  Date;  provided  that,  in the event of an
exchange  of all  or a  portion  of a  Global  Security  for  Physical  Security

Global Security.

         (b) The Trustee shall pay interest and Additional Interest,  if any, to
DTC, with respect to any Global Security held by DTC, on the applicable Interest
Payment Date in accordance with instructions  received from the Company at least
five  Business Days before the  applicable  Interest  Payment Date.  The Company
shall deliver such instructions in the form of an Officers'  Certificate setting
forth  Additional  Interest in the aggregate and per $1,000  principal amount of
Securities to be paid on such Interest Payment Date.

         SECTION 2.13     Outstanding Securities.
                          -----------------------

         Securities  outstanding at any time are all  Securities  that have been
authenticated by the Trustee except for those canceled by it, those delivered to
it for cancellation  and those described in this Section as not  outstanding.  A
Security  does not cease to be  outstanding  because  the  Company or one of its
Affiliates holds the Security.

         If a Security  is  replaced  pursuant  to Section  2.7, it ceases to be
outstanding  unless  the  Trustee  receives  proof  satisfactory  to it that the
replaced Security is held by a bona fide purchaser.

         If the Paying Agent holds on a redemption  date or Maturity  Date money
sufficient to pay the  principal of, and interest on Securities  payable on that
date,  then on and after that date such  Securities  cease to be outstanding and
interest on them ceases to accrue.

         SECTION 2.14     Treasury Securities.
                          --------------------

         In determining  whether the Holders of the required principal amount of
Securities have concurred in any direction,  waiver or consent, Securities owned
by the Company,  any Subsidiary or any of their  respective  Affiliates shall be
disregarded,  except that for the  purposes of  determining  whether the Trustee
shall be protected  in relying on any such  direction,  waiver or consent,  only
Securities that a Responsible Officer of the Trustee actually knows are so owned
shall be so disregarded.

         The Trustee may require an  Officers'  Certificate  listing  securities
owned by the Company, any Subsidiary or any of their respective Affiliates.

         SECTION 3.3      Election To Redeem; Notice to Trustee.
                          --------------------------------------

         The  election  of the  Company to redeem  any  Securities  pursuant  to
Section 3.1 shall be evidenced by a Board Resolution of the Company delivered to
the Trustee.  The Company shall,  at least 30 days prior to the Redemption  Date
fixed by the  Company  (unless a shorter  notice  shall be  satisfactory  to the
Trustee) notify the Trustee of such Redemption Date and of the principal  amount
of Securities to be redeemed.

          SECTION 3.4     Selection by Trustee of
                          Securities To Be Redeemed.
                          --------------------------

         If less than all the  Securities  of a Series are to be  redeemed,  the
particular  Securities to be redeemed shall be selected by the Trustee, from all
outstanding Securities of a Series not previously called for redemption, by such

the  selection  for  redemption  of  portions  (equal to $1,000 or any  integral
multiple thereof) of the principal amount of Securities of a denomination larger

         The Trustee  shall  promptly  notify the Company and the  Registrar  in
writing  of the  Securities  selected  for  redemption  and,  in the case of any
Securities selected for partial  redemption,  the principal amount thereof to be
redeemed.


<PAGE>

                                      -46-

         For all  purposes of this  Indenture,  all  provisions  relating to the

Securities which has been or is to be redeemed.

         SECTION 3.5      Notice of Redemption.
                          ---------------------

         Notice  of  redemption  shall  be given by  first-class  mail,  postage
prepaid,  mailed not less than 30 nor more than 60 days prior to the  Redemption

                  All notices of redemption shall state:

                    (1)    the Redemption Date,

         are to be redeemed,  the identification  including CUSIP numbers, (and,
         in the  case of  partial  redemption,  the  principal  amounts)  of the
         particular Securities to be redeemed,

                    (4) that on the Redemption  Date the  Redemption  Price will
         become due and payable upon each such Security to be redeemed and that,
         unless the Company shall default in the payment of the Redemption Price
         and any applicable  accrued  interest,  interest  thereon will cease to
         accrue on and after said date, and

                    (5) the  place or places  where  such  Securities  are to be
         surrendered for payment of the Redemption Price.

Trustee in the name and at the expense of the Company.

         SECTION 3.6      Deposit of Redemption Price.
                          ----------------------------

         On or prior to 10:00 a.m.  New York City time on any  Redemption  Date,

          SECTION 3.7      Securities Payable on Redemption Date.
                           -------------------------------------

         Notice of redemption having been given as aforesaid,  the Securities so
to be redeemed  shall,  on the  Redemption  Date,  become due and payable at the
Redemption  Price  therein  specified,  and from and after such date (unless the
Company shall default in the payment of the Redemption  Price and any applicable
accrued  interest) such Securities shall cease to bear interest.  Upon surrender
of any such  Security  for  redemption  in  accordance  with said  notice,  such
Security  shall be paid by the Paying Agent at the  Redemption  Price,  together
with any applicable accrued interest to the Redemption Date.

         If any  Security  called  for  redemption  shall  not be so  paid  upon
surrender  thereof for  redemption,  the  principal  (and  premium,  if any) and
accrued interest on such unpaid principal shall,  until paid, bear interest from
the Redemption Date at the rate provided by the Security.

          SECTION 3.8      Sinking Fund.
                           -------------

         (a) As and for a sinking fund for the retirement of the Debentures, the
Company  covenants  and  agrees  that  (so  long  as any of the  Debentures  are
outstanding)  it will, no later than 10:00 a.m. on each November 1st  commencing
with the year 2008 to and  including the year 2026 (each such November 1st being
herinafter  referred to as a "Mandatory Sinking Fund Redemption Date"),  deposit
with the  Trustee or any Paying  Agent (or,  if the Company is acting as its own
Paying Agent,  segregate and hold in trust),  a sum in cash sufficient to redeem
on  each  such  November  1st  $6,250,000  aggregate  principal  amount  of  the
Debentures (subject to adjustment as provided in paragraph (b)) at a price equal
to 100% of the principal  amount  thereof plus accrued  interest (not  otherwise
paid or  provided  to be paid  on or  before  the  Redemption  Date);  provided,
however,  that the sinking fund  requirement for any year shall never exceed the
principal amount of Notes at the time outstanding.  Each sum payable as provided
in this Secton 3.9 is herein called a "Mandatory Sinking Fund Payment Amount".

         (b) The  Mandatory  Sinking  Fund  Payment  Amount  shall be subject to
adjustment  in the  event  that  on or  prior  to  any  Mandatory  Sinking  Fund
Redemption  Date the Company  delivers or causes to be  delivered to the Trustee
for cancellation  Debentures with an aggregate principal amount in excess of the
Mandatory Sinking Fund Payment Amount for such next succeeding Mandatory Sinking
Fund  Redemption  Date, in which case the Mandatory  Sinking Fund Payment Amount
applicable  to each  Mandatory  


<PAGE>

                                      -48-

Sinking Fund Redemption Date after the next  succeeding  Mandatory  Sinking Fund
Redemption  Date shall be adjusted to be the  quotient  obtained by dividing (i)
the aggregate principal amount of Debentures  outstanding after giving effect to
such  cancellation  by (ii) the  number  of  remaining  Mandatory  Sinking  Fund
Redemption Dates including the next succeeding Mandatory Sinking Fund Redemption
Date.

         SECTION 3.9      Selection of Debentures.
                          ------------------------

         The Trustee  shall  select and call for  redemption  on each  Mandatory
Sinking Fund Redemption Date, on a pro rata basis,  such an aggregate  principal
amount of  outstanding  Debentures  as will exhaust the  Mandatory  Sinking Fund
Payment Amount, as nearly as in the opinion of the Trustee may be practical,  at
the  redemption  price of 100% of the  principal  amount  thereof plus  interest
accrued to the Redemption Date, and the Company shall cause notice of redemption
of such Debentures on such Mandatory  Sinking Fund Redemption Date to be give in
the name of the  Company  and in the  manner  provided  in  Section  3.5 for the
redemption of  Securities  in part at the option of the Company  except that the
notice of redemption  shall also state that the  Debentures  are being  redeemed
pursuant to the operation of the sinking fund;  and on and after such  Mandatory
Sinking Fund  Redemption  Date, if the necessary  funds have been deposited with
it, the Trustee  shall apply or cause to be applied  such sinking fund monies in
the manner  provided  in Section  3.7 to the  redemption  of the  Securities  so
selected.

          SECTION 3.10     Credit for Debentures Previously Acquired.
                           ------------------------------------------

         Notwithstanding any provision of Section 3.8 calling for payment of the
Mandatory  Sinking  Fund  Payment  Amount in cash,  the Company at its option in
satisfaction  of all or any part of any  Mandatory  Sinking Fund Payment  Amount
may, from time to time, by delivering to the Trustee not less than 45 days prior
to the date of such Mandatory  Sinking Fund  Redemption  Date, in lieu of paying
all or any part of any Mandatory Sinking Fund Payment Amount in cash, Debentures
for  cancellation  previously  authenticated  and delivered by the Trustee which
were acquired during the 12-month period  preceding such Mandatory  Sinking Fund
Redemption Date.

         The  Debentures  to be credited  pursuant to this Section 3.10 shall be
accompanied  by an Officers'  Certificate  which shall specify (i) the amount of
such  Mandatory  Sinking  Fund  Payment  Amount  to be made in cash and (ii) the
aggregate

                                      -49-

principal  amount of Debentures  being  delivered and credited  against  payment
pursuant to this Section 3.10 and  confirming  that no Default in the payment of
interest of the Debentures or Event of Default has occurred and is continuing.

                          ----------------------------

         Upon  surrender  of a Security  that is redeemed in part (with,  if the
Company or the Trustee so requires,  due endorsement by, or a written instrument
of transfer in form  satisfactory  to the Company and the Trustee duly  executed
by, the Holder thereof or his attorney duly authorized in writing),  the Company
shall  execute and the Trustee shall  authenticate  and deliver to the Holder of
such Security  without  service  charge,  a new Security or  Securities,  of any
authorized  denomination  as requested by such  Holder,  in aggregate  principal
amount equal to and in exchange for the  unredeemed  portion of the principal of
the Security so surrendered.

ties  may be  surrendered  for  registration  of  transfer  or  exchange  or for
presentation for payment and where notices and demands to or upon the Company in
respect of the  Securities  and this  Indenture may be served.  The Company will
give prompt written notice to the Trustee of the location, and any change in the

maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof,  such presentations,  surrenders,  notices and demands
may be made or served at the address of the Trustee set forth in Section 10.2.

         The  Company  may also from time to time  designate  one or more  other
offices or agencies where the Securities may be presented or surrendered for any
or all  such  purposes  and may from  time to time  rescind  such  designations,

Company of its  obligation  to  maintain  an office or agency in the  Borough of
Manhattan, the City of New York, for such purposes. The Company will give prompt
written  notice to the Trustee of any such  designation or rescission and of any
change in the location of any such other office or agency.

         SECTION 4.8      Limitation on Debt.

                  of  assets  to the  Company  or  other  Person  that  made the
                  original  Investment  from the Person in which such Investment
                  was made or  resulting  from the  sale or  disposition  of the
                  Investment or other return of the amount of the  Investment or
                  from the  redesignation  of any  Unrestricted  Subsidiary as a

                  purposes of the calculation to be made pursuant to this clause
                  (3),  shall not exceed the amount of the original  Investment;

                  Restricted  Subsidiary to make a Restricted  Payment which has

provided  that the  foregoing  clause (c) shall not  prevent  the payment of any
dividend within 60 days after the date of its declaration if such dividend could
have  been  made  on  the  date  of its  declaration  without  violation  of the
provisions of this Section 4.13.

          For  purposes of clause  (c)(2)  above,  the  aggregate  net  proceeds
received  by the Company  (x) from the  issuance  of its Capital  Stock upon the
conversion of, or exchange for, securities evidencing Debt of the Company, shall
be calculated on the  assumption  that the gross proceeds from such issuance are
equal to the  aggregate  principal  amount (or, if discount  Debt,  the accreted
principal  amount)  of the  Debt  evidenced  by  such  securities  converted  or
exchanged  and (y) upon the  conversion  or exchange of other  securities of the
Company shall be equal to the aggregate net proceeds of the original sale of the
securities so converted or exchanged if such proceeds of such original sale were
not  previously  included in any  calculation  for the purposes of clause (c)(2)
above plus any additional sums payable upon conversion or exchange.

          The Company's  obligation to comply with this covenant shall terminate
if and when the Securities become Investment Grade.

          If an  Investment  which the Company or any  Restricted  Subsidiary is
obligated  to make either in part from time to time or in whole in the future is
fixed in amount by the agreement setting forth such obligation,  for purposes of
determining whether such Investment is a Restricted Payment permitted under this
Section 4.13 or is a Permitted  Payment,  the Investment shall be deemed to have
been made only once, in the amount so fixed,  at the time the  obligation  first
arises  (and not when  payments  in  respect  thereof  are  later  made).  If an
Investment  which the Company or any Restricted  Subsidiary is obligated to make
either  in part  from  time to time or in whole in the  future  is not  fixed in
amount  by  the  agreement  setting  forth  such  obligation,  for  purposes  of
determining whether such Investment is a Restricted Payment permitted under this
Section 4.13 or is a Permitted  Payment,  the Investment shall be deemed to have
been made at the time the obligation  first arises in an amount to be determined
in good faith by the Board of Directors, as evidenced by a Board Resolution, and
any  actual  payments  in  respect  of such  Investment  shall be  deemed  to be
Investments made on the date of payment thereof.  Subject to the terms of clause
(v) of the  definition  of Permitted  Payments,  such later  Investments  may be
Permitted Payments.

on the ability of any  Restricted  Subsidiary  to (i) pay  dividends or make any
other  distributions  permitted by  applicable  law on any Capital Stock of such
Restricted  Subsidiary owned by the Company or any other Restricted  Subsidiary,
(ii) make  payments  in  respect  of any Debt owed to the  Company  or any other
Restricted Subsidiary,  (iii) make loans or advances to the Company or any other
Restricted Subsidiary or (iv) transfer any of its Property to the Company or any
other  Restricted  Subsidiary.  The  Company's  obligation  to comply  with this
covenant will terminate if and when the Securities become Investment Grade.

          This Section 4.14 shall not restrict or prohibit any  encumbrances  or
restrictions  existing:  (i) in  connection  with  the  Incurrence  of any  Debt
permitted  under clauses (iii),  (vi),  (vii),  (x) or (xi) of Section 4.9(b) or
with  respect  to any  portion  thereof  that is also  Debt of the  Company  and
permitted under Section 4.8; provided that such encumbrances or restrictions are
required  in  order  to  effect  such  financing  and  are not  materially  more
restrictive,  taken as a whole,  on the  ability  of the  applicable  Restricted
Subsidiary to make the  payments,  distributions,  loans,  advances or transfers
referred  to in  clauses  (i)  through  (iv)  of the  preceding  paragraph  than
encumbrances and restrictions,  taken as a whole,  customarily  accepted (or, in
the absence of any industry  custom,  reasonably  acceptable)  in  substantially
non-recourse  project  financing,  (ii) in  connection  with the  execution  and
delivery of an electric power or thermal energy purchase  contract to which such
Restricted  Subsidiary is the supplying party or other contracts with customers,
suppliers and  contractors  to which such  Restricted  Subsidiary is a party and
where such Restricted  Subsidiary is engaged in the  development,  construction,
acquisition  or  operation  of a  Power  Supply  Business;  provided  that  such
encumbrances or restrictions  are required in order to effect such contracts and
are not materially  more  restrictive,  taken as a whole,  on the ability of the
applicable  Restricted  Subsidiary to make the payments,  distributions,  loans,
advances or transfers  referred to in clauses (i) through (iv) in the  preceding
paragraph than  encumbrances  and  restrictions,  taken as a whole,  customarily
accepted (or, in the absence of any industry custom,  reasonably  acceptable) in
substantially  non-recourse  project  financing,  (iii) in  connection  with the
Incurrence of any Debt permitted under clause (iv) of Section  4.9(b),  provided
that such encumbrances or restrictions  taken as a whole are not materially more
restrictive on the ability of the applicable  Restricted  Subsidiary to make the
payments, distributions, loans, advances or transfers referred to in

effect,  taken  as a  whole,  in  connection  with  the  Debt  so  exchanged  or
refinanced,  (iv) in connection  with the Bank Credit  Agreement and the project
financing,  electric power and thermal energy  purchase  arrangements  and other
contracts  with  customers,  suppliers and  contractors in effect on the Closing
Date, including extensions,  refinancings, renewals or replacements thereof, (v)
pursuant to customary  non-assignment  provisions  in leases,  (vi)  pursuant to
restrictions  imposed pursuant to any stock purchase or asset purchase agreement
pending the  consummation of the  transactions  contemplated  thereby,  (vii) in
connection  with  any  Acquisition  Debt,  provided  that  such  encumbrance  or
restriction  was  not  incurred  in  contemplation  of the  obligor  becoming  a
Restricted  Subsidiary of the Company,  which  encumbrance or restriction is not
applicable  to any Person,  or the Property or assets of any Person,  other than
the Person, or the Property or assets,  acquired,  (viii) customary restrictions
on transfers of Property subject to a Lien which could not materially  adversely
affect the Company's  ability to satisfy its obligations under the Indenture and
the  Securities  or (ix)  provisions  contained  in  agreements  or  instruments
relating to Debt which prohibit the transfer of all or substantially  all of the
assets  of the  obligor  thereunder  unless  the  transferee  shall  assume  the
obligations  of the obligor under such  agreement or  instrument,  in each case;
provided  that,  in the  case  of  clause  (iv)  above,  such  encumbrances  and
restrictions, taken as a whole, in any such extensions,  refinancings,  renewals
or  replacements  are not  materially  more  restrictive  on the  ability of the
applicable  Restricted  Subsidiary to make the payments,  distributions,  loans,
advances or transfers  referred to in clauses (i) through (iv) in the  preceding
paragraph than those  encumbrances  or  restrictions  taken as a whole in effect
immediately  before such extension,  refinancing,  renewal or replacement.  This
Section 4.14 shall not prevent the Company from granting any Liens not expressly
prohibited hereby.

          SECTION 4.15      Limitation on Asset Dispositions.
                            ---------------------------------

          (a) The  Company  shall not make,  and  shall  not  permit  any of its
Restricted  Subsidiaries to make, any Asset  Disposition  unless the Company (or
the Restricted  Subsidiary,  as the case may be) receives  consideration  at the
time of each such Asset  Disposition  at least equal to the fair market value of
the shares or assets sold or  otherwise  disposed of (such  amounts in excess of
$50 million determined in good faith by the Board of Directors,  as evidenced by
a Board  Resolution)  and  either  (i) not less  than  75% of the  consideration
received by


<PAGE>

                                      -66-

the Company (or such Restricted  Subsidiary,  as the case may be) is in the form
of cash or  property  or assets  used or useful in a Power  Supply  Business  or
Capital Stock of a Person primarily engaged in a Power Supply Business, provided
that any note or other  obligation  received by the Company (or such  Restricted
Subsidiary,  as the case may be) that is converted  into cash within 180 days of
such Asset  Disposition  and any  liabilities (as shown on the Company's or such
Restricted  Subsidiary's  most  recent  balance  sheet)  of the  Company  or any
Restricted  Subsidiary  that are  assumed by the  transferee  of any such assets
shall be deemed to be cash for purposes of this clause (i), and (ii) first,  the
Net Cash Proceeds of such Asset  Disposition are applied within 90 days from the
later of the date of such Asset  Disposition or the receipt of Net Cash Proceeds
related thereto, to the payment of the principal of, premium and interest on any
Senior Debt of the Company (including to cash  collateralize  letters of credit)
and, in connection with any such payment,  any related loan commitment,  standby
facility  or the like shall be  permanently  reduced  in an amount  equal to the
principal amount so repaid and second,  to the extent such Net Cash Proceeds are
not required by the lenders,  or the terms,  of the Senior Debt to be applied in
accordance  with the  foregoing  or, if after being so applied  there remain Net
Cash Proceeds, then at the Company's election, such Net Cash Proceeds are either
(x)  invested  in  the  business  or  businesses  of the  Company  or any of its
Restricted   Subsidiaries  consistent  with  Section  4.4;  provided  that  such
investment  is made  within  365 days from the  later of the date of such  Asset
Disposition  or the  receipt  of the Net Cash  Proceeds  related  thereto or (y)
applied  to the  payment  of any  Senior  Debt  of the  Company  or  Debt of any
Restricted  Subsidiary or any Consolidated  Subsidiary  (other than Debt owed to
the Company or another Restricted Subsidiary),  and, in connection with any such
payment,  any related  loan  commitment,  standby  facility or the like shall be
permanently  reduced  in an amount  equal to the  principal  amount  so  repaid;
provided  that such Net Cash  Proceeds are so applied  within three months after
the  expiration  of the  365-day  period  referred to in clause (x) above or (z)
applied to make a tender offer (the  "Offer") to purchase  Securities  and other
Debt of the  Company  from  time to time  outstanding  with  similar  provisions
requiring  the  Company to make an offer to purchase or to redeem such Debt with
the  proceeds  from  assets  sales,  pro rata in  proportion  to the  respective
principal  amounts  (or  accreted  values  in the  case of Debt  issued  with an
original issue discount) of the Notes (if then outstanding),  the Debentures and
such other Debt then  outstanding at a purchase price of 100% of their principal
amount (or  accreted  value in the case of Debt issued  with an  original  issue
discount), plus accrued interest

(subject to proration in the event of  oversubscription  in the manner set forth
below).  Notwithstanding the foregoing, to the extent that any or all of the Net
Cash  Proceeds of any Foreign  Asset  Disposition  are  prohibited or delayed by
applicable  local law from being  repatriated  to the U.S., the Company (or such
Restricted  Subsidiary,  as the case may be) shall not be  required to apply the
portion of such Net Cash  Proceeds so affected  in  accordance  with clause (ii)
above (other than to repay Debt of the Restricted  Subsidiary  making such Asset
Disposition or Debt of a Consolidated Subsidiary of the Company, in each case as
contemplated  by clause (ii) above and to the extent the prohibition or delay on
repatriation  is not  applicable to such  repayment and such repayment is not in
violation of the terms of any Senior Debt) (the Company hereby agreeing to cause
the applicable  Restricted  Subsidiary to promptly take all actions  required by
the applicable local law to permit such  repatriation);  provided that once such
repatriation  of any such  affected  Net Cash  Proceeds is  permitted  under the
applicable local law, such  repatriation  will be immediately  effected and such
repatriated  Net Cash  Proceeds  will be applied in the manner set forth in this
Section 4.15. To the extent that dividends or distributions of any or all of the
Net Cash  Proceeds  of any  Foreign  Asset  Disposition  would  result  in a tax
liability  greater  than that which would be incurred if such Net Cash  Proceeds
were not so dividended or distributed,  the Net Cash Proceeds so affected may be
retained by the applicable Restricted Subsidiary for so long as such adverse tax
liability would continue to be incurred.

          Notwithstanding anything in this covenant to the contrary, the Company
and any Restricted Subsidiary may make the following Asset Dispositions:

                    (i) a disposition  resulting  from the bona fide exercise by
          governmental  authority  of its  claimed  or actual  power of  eminent
          domain;

                    (ii) a realization upon a security interest;

                    (iii) any Permitted  Payment or  Restricted  Payment that is
          permitted hereunder; or

                    (iv)  any  sale,  transfer,   conveyance,   lease  or  other
          disposition   of  the  Capital  Stock  or  Property  of  a  Restricted
          Subsidiary pursuant to the terms of any power sales agreement or steam
          sales agreement or other  agreement or contract  related to the output
          or product of, or services  rendered by, a Power Supply Business as to
          which 


<PAGE>

                                      -68-

          such Restricted  Subsidiary is the supplying  party;  provided that to
          the extent the Company or any Restricted  Subsidiary receives any cash
          consideration in connection with such Asset Disposition,  the Net Cash
          Proceeds  from such Asset  Disposition  shall be applied in accordance
          with clause (ii) of this Section 4.15.

          (b) If the  aggregate  purchase  price of  Securities  and other  Debt
tendered  pursuant to an Offer made pursuant to clause  (ii)(z) clause (a) above
is less than the Net Cash  Proceeds  allotted to the purchase of the  Securities
and other Debt,  the Company may use the remaining Net Cash Proceeds for general
corporate  purposes.  The  Company  will  not be  required  to  comply  with the
provisions of clause (ii) in the first paragraph of this Section 4.15 if the Net
Cash Proceeds from one or more Asset Dispositions occurring on or after the date
of the  Indenture  are less than $40 million in any one fiscal year.  Any lesser
amounts so carried  forward and cumulated need not be segregated or reserved and
may be used for general corporate purposes.

          (c) (i)  Promptly,  and in any  event  within  30 days  from the Asset
Disposition  and the  receipt of the Net Cash  Proceeds  as to which the Company
must make an Offer, the Company shall be obligated to deliver to the Trustee and
send, by first-class mail to each Holder of Securities, a written notice stating
that:

          (A) an Asset Disposition has occurred and that such Holders may tender
          all or any  portion  of  their  Securities  pursuant  to the  Offer in
          integral  multiples  of $1,000  principal  amount,  at the  applicable
          purchase price;

          (B) any Security not tendered or accepted for payment will continue to
          accrue interest;

          (C) any  Security  accepted  for  payment  pursuant to the Offer shall
          cease to accrue  interest after the Purchase Date (as defined  below);
          and

          (D) holders of Securities  will be entitled to withdraw their election
          in the manner described in clause (iii) of this Section 4.15(c).

The notice shall  specify a purchase date not less than 30 days nor more than 60
days after the date of such  notice (the  "Purchase  Date"),  shall  include all
instructions  and  materials  necessary to enable each holders of  Securities to
tender Secu-


<PAGE>

                                      -69-

rities  pursuant  to the Offer  and shall  contain  information  concerning  the
business of the Company  which the  Company in good faith  believes  will enable
such holder to make an informed  decision  (which at a minimum  will include (1)
the  most  recently  filed  Annual  Report  on  Form  10-K  (including   audited
consolidated  financial statements) of the Company, the most recent subsequently
filed  Quarterly  Report on Form 10-Q and any Current  Report on Form 8-K of the
Company filed  subsequent to such Quarterly  Report,  other than Current Reports
describing  other  asset  dispositions   otherwise  described  in  the  offering
materials (or corresponding  successor reports or reports otherwise  required to
be delivered to holder of Securities if the Company is no longer filing  reports
pursuant to the Securities  Exchange Act of 1934), (2) a description of material
developments in the Company's  business  subsequent to the date of the latest of
such Reports, and (3) if material, appropriate pro forma financial information).

          (ii) Not later than the date upon which written  notice of an Offer is
delivered to the Trustee as provided  above,  the Company  shall  deliver to the
Trustee an Officers'  Certificate  as to (A) the amount of the Offer (the "Offer
Amount"),  (B) the  allocation of the Net Cash  Proceeds  pursuant to which such
Offer  is  being  made  and  (C) the  compliance  of such  allocation  with  the
provisions  of this Section  4.15.  Not later than one Business Day prior to the
Purchase  Date, the Company shall also  irrevocably  deposit with the Trustee or
with the Paying  Agent (or,  if the  Company is acting as its own Paying  Agent,
segregate and hold in trust) in immediately  available  funds an amount equal to
the Offer Amount to be held for payment in  accordance  with the  provisions  of
this Section 4.15. Upon the expiration of the period for which the Offer remains
open (the  "Offer  Period"),  the  Company  shall  deliver  to the  Trustee  the
Securities or portions  thereof which have been properly  tendered to and are to
be accepted by the  Company.  The Trustee or the Paying  Agent (if any),  or the
Company if acting as its own Paying Agent,  shall, on the Purchase Date, mail or
deliver payment to each tendering Holder in the amount of the purchase price. In
the event that the aggregate  purchase price of the Securities  delivered by the
Company to the Trustee or the Paying  Agent (if the Company is not acting as its
own  Paying  Agent) is less than the Offer  Amount,  the  Trustee  or the Paying
Agent,  as the case may be, shall deliver the excess to the Company  immediately
after the expiration of the Offer Period.

          (iii)  Any  holder  of  Securities  electing  to have  his  Securities
purchased  will be required to surrender  such  Securities,  with an appropriate
form duly  completed,  to the Trus-


<PAGE>

                                      -70-

tee at the address specified in the notice by the close of business at least one
Business Day prior to the Purchase Date.  Holders of Securities will be entitled
to withdraw  their election if the Trustee or Paying Agent (if any) receives not
later than the close of business on the Business Day prior to the Purchase  Date
a facsimile  transmission  or letter  setting forth the name of the Holder and a
statement that such Holder is withdrawing  his election to have all or a portion
of his  Securities  purchased.  If at the  expiration  of the Offer  Period  the
aggregate  principal  amount of Securities  surrendered by holders of Securities
exceeds  the Offer  Amount,  the  Company  shall  select  the  Securities  to be
purchased  on a  pro  rata  basis  (with  such  adjustments  as  may  be  deemed
appropriate by the Company so that only Securities in denominations of $1,000 or
integral  multiples thereof,  shall be purchased).  Holders whose Securities are
purchased only in part will be issued new Securities of the same Series equal in
principal amount to the unpurchased portion of the Securities surrendered.

          (iv) At the time the Company delivers  Securities to the Trustee which
are to be accepted  for  purchase,  the Company  will also  deliver an Officers'
Certificate  stating  that such  Securities  are to be  accepted  by the Company
pursuant to and in  accordance  with the terms of this Section  4.15. A Security
shall be deemed to have been  accepted  for  purchase  at the time the  Trustee,
directly or through an agent,  or the Company if acting as its own Paying Agent,
mails or makes  available  for  delivery  payment  therefor to the  surrendering
Holder.

          (d) In the event the  Company is unable to  purchase  Securities  from
Holders thereof in an Offer because such purchase is prohibited by any provision
of applicable law, the Company need not make an Offer. The Company shall then be
obligated to use such Net Cash Proceeds in accordance  with clause  (i)(B)(x) or
(y) of this Section 4.15(c).

          (e) Whenever Net Cash Proceeds are received by the Company,  and prior
to the allocation of such Net Cash Proceeds  pursuant to this Section 4.15, such
Net Cash  Proceeds  shall be set  aside by the  Company  in a  separate  account
pending allocation.

          The Company  will  comply  with all  applicable  tender  offer  rules,
including  without  limitation  Rule 14e-1 under the Exchange Act, in connection
with an Offer under the provisions of this covenant.

          such Debt or

                    (ii) as a result of such default,  the maturity of such Debt
          shall  have been  accelerated  so that the same shall be or become due
          and payable prior to the date on which the same would  otherwise  have

          not paid or due upon  acceleration  and the Company could, at the time
          of  default,  incur at  least $1 of Debt  under  Section  4.8(a);  and
          provided, further, however that, subject to the provisions of Sections
          7.1 and 7.2, the Trustee  shall not be charged  with  knowledge of any
          such default  unless  written  notice thereof shall have been given to
          the Trustee by the Company, by the holder or an agent of the holder of
          any such Debt, by the trustee then acting under any indenture or other
          instrument  under which such default  shall have  occurred,  or by the
          Holders of not less than 25% in the aggregate  principal amount of the
          Securities at the time outstanding;

          (d) the Company  defaults in the  performance of or breaches any other

but treating any deductibles,  self insurance or retentions as not so covered by
insurance) and which judgments or orders shall not be discharged or waived,  and
shall remain  outstanding  and there shall be any period of 60 consecutive  days
following  entry of such  judgment  or order in  excess  of $50  million  or the
judgment or order which causes the aggregate amount to exceed $50 million during
which a stay of  enforcement  of such judgment or order,  by reason of a pending
appeal or otherwise,  shall not be in effect;  provided, that such a judgment or
order  shall not be an Event of Default if such  judgment  or order is against a
Significant  Subsidiary  and does not require any payment by the Company and the
Company could, at the expiration of the applicable 60 day period, incur at least
$1 of Debt under Section 4.8;

          (f) a court having  jurisdiction  in the  premises  enters a decree or

Trustee or any Holder. The Holders of at least a majority in principal amount of
the  outstanding  Securities  may,  by written  notice to the Company and to the
Trustee,  waive all past defaults with respect to the Securities and rescind and
annul a  declaration  of  acceleration  with respect to the  Securities  and its
consequences if (i) all existing Events of Default applicable to the Securities,
other than the nonpayment of the principal of, Change in Control  purchase price
or premium,  if any, and interest on the Securities  that have become due solely
by such  declaration  of  acceleration,  have been  cured or waived and (ii) the
rescission  would  not  conflict  with  any  judgment  or  decree  of a court of
competent jurisdiction.

          SECTION 6.3      Other Remedies.
                           --------------

          If an Event of  Default  occurs and is  continuing,  the  Trustee  may
pursue any  available  remedy by  proceeding  at law or in equity to collect the
payment  of  principal  of or  interest  on the  Securities  or to  enforce  the
performance of any provision of the Securities or this Indenture.

          The Trustee may maintain a proceeding  even if it does not possess any
of the  Securities  or does not produce any of them in the  proceeding,  and any
such  proceeding  instituted  by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the  reasonable  compensation,  expenses,  disbursements  and
advances of the Trustee,  its agents and counsel,  be for the ratable benefit of
the  Holders  of the  Securities  in respect  of which  such  judgment  has been
recovered.

          SECTION 6.4      Waiver of Past Default.
                           -----------------------

Default and its consequences,  except a Default or Event of Default specified in
Section  6.1(a)  or (b) or a  Default  or Event of  Default  in  respect  of any
provision  hereof which cannot be modified or amended without the consent of the
Holder so affected  pursuant to Section 9.2.  When a Default or Event of Default
is so waived,  it shall be deemed  cured and cease to exist;  but no such waiver
shall extend to any  subsequent  or other  Default or Event of Default or impair
any right consequent thereto.

                           --------------------

          The Holders of at least a majority in  aggregate  principal  amount of
the  outstanding  the  Securities  may  direct  the time,  method,  and place of
conducting any proceeding for any remedy  available to the Trustee or exercising
any trust or power conferred on the Trustee.  However, the Trustee may refuse to
follow any direction that conflicts with law or this Indenture, that may involve
the Trustee in personal liability,  or that the Trustee determines in good faith
may be unduly prejudicial to the rights of Holders of the Securities not joining
in the giving of such  direction  and may take any other  action it deems proper
that is not  inconsistent  with any such direction  received from Holders of the
Securities.

          SECTION 6.6      Limitation on Suits.

          notice of a continuing Event of Default;

                    (b) the  Holders  of at  least  25% in  aggregate  principal
          amount of the then  outstanding  Securities  make a written request to
          the Trustee to pursue a remedy;

                    (c) such Holder or Holders offer and, if requested,  provide
          to the  Trustee  indemnity  reasonably  satisfactory  to  the  Trustee
          against any costs, liability or expense;

                    (d) the Trustee  does not comply with the request  within 60
          days after receipt of the request and offer of indemnity; and

          majority  in  aggregate  principal  amount  of  the  then  outstanding
          Securities do not give the Trustee a direction  which is  inconsistent
          with the request.

          A Holder may not use this Indenture to prejudice the rights of another
Securityholder   or  to  obtain  a  preference   or  priority  over  such  other
Securityholder.

                          ------------------------------------

after such  respective  dates,  is absolute and  unconditional  and shall not be
impaired or affected without the consent of such Holder.

for the  whole  amount of  principal  and  accrued  interest  remaining  unpaid,
together with interest  overdue on principal  and, to the extent that payment of
such interest is lawful,  interest on overdue installments of interest,  in each
case at the Interest  Rate and such  further  amount as shall be  sufficient  to
cover  the  costs  and  expenses  of   collection,   including  the   reasonable
compensation,  expenses,  disbursements and advances of the Trustee,  its agents
and counsel.

            SECTION 6.9     Trustee May File Proofs of Claim.
                            ---------------------------------

Company or any of its  Subsidiaries  (or any other obligor upon the Securities),
its creditors or its property and shall be entitled and empowered to collect and
receive any monies or other  property  payable or deliverable on any such claims
and to distribute the same,  and any Custodian in any such judicial  proceedings
is hereby authorized by each Securityholder to make such payments to the Trustee

directly  to the  Holders,  to pay to the  Trustee  any amount due to it for the
reasonable  compensation,  expenses,  disbursements and advances of the Trustee,
its agent and counsel,  and any other amounts due the Trustee under Section 7.7.
Nothing herein  contained  shall be deemed to authorize the Trustee to authorize
or  consent  to or accept or adopt on behalf of any  Securityholder  any plan of
reorganization,  arrangement, adjustment or composition affecting the Securities
or the rights of any Holder  thereof,  or to  authorize  the  Trustee to vote in
respect of the claim of any Holder in any such proceeding.

          interest; and

          Third:  subject to Article XI, to Holders for principal  amounts owing

          SECTION 6.11     Undertaking for Costs.
                           ----------------------

Indenture  or in any suit against the Trustee for any action taken or omitted by
it as  Trustee,  a court in its  discretion  may require the filing by any party
litigant  in the suit of an  undertaking  to pay the costs of the suit,  and the

                                      -79-

not prevent the  concurrent  assertion or  employment  of any other  appropriate
right or remedy.

          SECTION 6.13      Delay or Omission Not Waiver.
                            -----------------------------

          No delay or omission  of the Trustee or of any Holder of any  Security
to exercise any right or remedy  accruing upon any Event of Default shall impair
any such right or remedy or  constitute a waiver of any such Event of Default or
an  acquiescence  therein.  Every right and remedy given by this Article 6 or by
law to the Trustee or to the Holders may be exercised  from time to time, and as
often as may be deemed expedient,  by the Trustee or by the Holders, as the case
may be.

any  right  or  remedy  under  this  Indenture  and  such  proceeding  has  been
discontinued or abandoned for any reason,  or has been  determined  adversely to
the  Trustee  or to  such  Holder,  then  and  in  every  case,  subject  to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored  severally and respectively to their former positions  hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

          SECTION 7.1        Duties of Trustee.
                             ------------------

          (a) If an Event of Default actually known to a Responsible  Officer of
the Trustee has occurred and is  continuing,  the Trustee shall exercise such of
the rights and powers vested in it by this  Indenture and use the same degree of
care and skill in their exercise as a prudent person would exercise or use under
the circumstances in the conduct of his own affairs.

          (b) Except during the continuance of an Event of Default:

                    (i) The  Trustee  need  perform  only  those  duties  as are
          specifically set forth in this Indenture or the TIA


<PAGE>

                                      -80-

          into this Indenture against the Trustee.

                    (ii) In the  absence of bad faith on its part,  the  Trustee
          may  conclusively  rely,  as to the  truth of the  statements  and the
          correctness of the opinions  expressed  therein,  upon certificates or
          opinions  furnished to the Trustee and conforming to the  requirements
          of this  Indenture.  However,  in the case of any such  certificate or
          opinions which by any provision hereof are specifically required to be
          furnished to the Trustee,  the Trustee shall examine such certificates
          and  opinions  to  determine  whether  or  not  they  conform  to  the
          requirements of this Indenture.

           (c)  Notwithstanding  anything to the contrary herein contained,  the
Trustee may not be relieved from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that:

                      (i) This  paragraph does not limit the effect of paragraph
           (b) of this Section 7.1.

                      (ii) The  Trustee  shall  not be  liable  for any error of
           judgment  made in good faith by a Responsible  Officer,  unless it is
           proved that the Trustee was negligent in  ascertaining  the pertinent
           facts.

                      (iii) The Trustee  shall not be liable with respect to any
           action it takes or omits to take in good faith in  accordance  with a
           direction received by it pursuant to Sections 6.2, 6.4 and 6.5.

           (d) No  provision  of this  Indenture  shall  require  the Trustee to
expend or risk its own funds or otherwise  incur any financial  liability in the
performance  of any of its duties  hereunder  or in the  exercise  of any of its
rights  or  powers  if it shall  have  reasonable  grounds  for  believing  that
repayment of such funds or adequate  indemnity against such risk or liability is
not reasonably assured to it.

           (e) Every  provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b), (c) and (d) of this Section 7.1.

           (f) The  Trustee  shall  not be  liable  for  interest  on any  money
received  by it except as the  Trustee  may agree in writing  with the  Company.
Money held in trust by the  Trustee

need not be segregated from other funds except to the extent required by law.

           SECTION 7.2     Rights of Trustee.
                           ------------------

           Subject to Section 7.1:

                      (a) The Trustee may rely and shall be  protected in acting
           or refraining from acting upon any document reasonably believed by it
           to be  genuine  and to have been  signed or  presented  by the proper
           Person. The Trustee shall not be bound to make any investigation into
           the  facts  or  matters  stated  in  any   resolution,   certificate,
           statement,  instrument,  opinion, report, notice, request, direction,
           consent, order, bond, debenture, note, other evidence of indebtedness
           or other paper or document,  but the Trustee, in its discretion,  may
           make such further inquiry or investigation into such facts or matters
           as it may see fit, and, if the Trustee  shall  determine to make such
           further inquiry or investigation,  it shall be entitled during normal
           business hours and upon  reasonable  advance notice to the Company to
           examine the books, records and premises of the Company, personally or
           by agent or attorney.

                      (b) Before the Trustee  acts or refrains  from acting with
           respect to any matter contemplated by this Indenture,  it may require
           an  Officers'  Certificate  or an Opinion  of  Counsel,  which  shall
           conform to the  provisions of Section 10.5.  The Trustee shall not be
           liable  for any  action  it takes  or omits to take in good  faith in
           reliance on such certificate or opinion.

                      (c) The Trustee may act through its  attorneys  and agents
           and shall not be responsible  for the misconduct or negligence of any
           agent (other than the  negligence  or willful  misconduct of an agent
           who is an employee of the Trustee) appointed with due care.

                      (d) The  Trustee  shall  not be liable  for any  action it
           takes or omits to take in good faith and without  negligence which it
           reasonably  believes to be  authorized or within its rights or powers
           conferred upon it by this Indenture or the TIA.

                      (e) The Trustee may consult with counsel of its  selection
           and the advice or opinion of such  counsel as to matters of law shall
           be full and complete authorization


<PAGE>

                                      -82-

           and protection from liability in respect of any action taken, omitted
           or suffered by it hereunder in good faith and in accordance  with the
           advice or opinion of such counsel.

                      (f) The Trustee  shall not be deemed to have notice of any
           Default  or Event of  Default  unless a  Responsible  Officer  of the
           Trustee has actual knowledge  thereof or unless written notice of any
           event  which is in fact such a default is  received by the Trustee at
           the Corporate Trust Office of the Trustee, and such notice references
           the Securities and this Indenture.

           SECTION 7.3      Individual Rights of Trustee.
                            -----------------------------

           The  Trustee in its  individual  capacity or any other  capacity  may
become  the owner or  pledgee  of  Securities  and may  otherwise  deal with the
Company,  or its  Subsidiaries and Affiliates with the same rights it would have
if it were not Trustee. Any Agent may do the same with like rights. However, the
Trustee is subject to Sections 7.10 and 7.11.

           SECTION 7.4      Trustee's Disclaimer.
                            ---------------------

           The Trustee makes no representation as to the validity or adequacy of
this  Indenture  or the  Securities,  and it shall  not be  accountable  for the
Company's  use of  the  proceeds  from  the  Securities,  and  it  shall  not be
responsible for any statement of the Company in this Indenture, or any statement
in the Securities other than the Trustee's certificate of authentication.

           SECTION 7.5      Notice of Defaults.
                            -------------------

           If a Default or an Event of Default  with  respect to the  Securities
occurs and is  continuing  and a  Responsible  Officer of the  Trustee  receives
written  notice of such Default or Event of Default,  the Trustee  shall mail to
each  Securityholder  notice of the  Default or Event of Default  within 90 days
after the occurrence  thereof in accordance  with TIA ss. 313(c).  Except in the
case of a Default or an Event of Default in payment of  principal of or interest
on any Security, including on acceleration, and the failure to make payment when
required  by Section  4.11,  and except in the case of a failure to comply  with
Article V hereof, the Trustee may withhold the notice to the Securityholders for
a  period  not to  exceed  60 days if and so long as a  committee  of its  Trust
Officers in good faith deter-


<PAGE>

                                      -83-

mines that withholding the notice is in the interest of Securityholders.

           SECTION 7.6       Reports by Trustee to Holders.
                             -----------------------------

           To the extent required by TIA ss. 313(a), within 60 days after July 1
of each  year  commencing  with  1998  and for as long as there  are  Securities
outstanding hereunder, the Trustee shall mail to each Holder the Company's brief
report dated as of such date that complies with TIA ss. 313(a). The Trustee also
shall  comply  with TIA ss.  313(b)  and TIA ss.  313(c) and (d). A copy of such
report at the time of its  mailing  to  Securityholders  shall be filed with the
SEC, if required,  and each stock exchange,  if any, on which the Securities are
listed.

           The  Company  shall  promptly  notify the  Trustee if the  Securities
become  listed on any stock  exchange and the Trustee  shall comply with TIA ss.
313(d).

            SECTION 7.7      Compensation and Indemnity.
                             ---------------------------

           The  Company  shall  pay to the  Trustee,  the  Paying  Agent and the
Registrar from time to time such compensation as shall be agreed in writing with
the Company from time to time for their respective  services rendered hereunder.
The Trustee's,  the Paying Agent's and the Registrar's compensation shall not be
limited  by any law in regard to the  compensation  of a trustee  of an  express
trust.  The  Company  shall  reimburse  the  Trustee,  the Paying  Agent and the
Registrar upon request for all reasonable out-of-pocket disbursements,  expenses
and advances  (including  reasonable  fees and expenses of counsel)  incurred or
made by each of them in connection  with  entering  into this  Indenture and the
performance of its duties under this Indenture,  in addition to the compensation
for their respective services under this Indenture.  Such expenses shall include
the reasonable  compensation,  out-of-pocket  disbursements  and expenses of the
Trustee's, the Paying Agent's and the Registrar's agents and counsel.

           The Company  shall  indemnify  the Trustee,  the Paying Agent and the
Registrar  for,  and hold each of them  harmless  against,  any and all  claims,
demands,  expenses  (including but not limited to attorneys' fees and expenses),
loss or liability  incurred by each of them arising out of or in connection with
the acceptance or  administration  of this Indenture and their respective duties
hereunder.  Each of the Trustee, the Paying Agent and the Registrar shall notify
the  Company  promptly  of any claim  asserted  against it for which it may seek
indemnity. 


<PAGE>

                                      -84-

However,  failure by the Trustee, the Paying Agent or the Registrar to so notify
the Company  shall not relieve the  Company of its  obligations  hereunder.  The
Company  need  not  reimburse  any  expense  or  indemnify  against  any loss or
liability incurred by the Trustee, the Paying Agent or the Registrar through the
Trustee's,  the  Paying  Agent's  or the  Registrar's,  as the case may be,  own
willful misconduct, negligence or bad faith.

           To secure the Company's payment obligations in this Section 7.7, each
of the Trustee,  the Paying Agent and the  Registrar  shall have a lien prior to
the Securities on all money or property held or collected by it, in its capacity
as Trustee,  Paying  Agent or  Registrar,  as the case may be,  except  money or
property held in trust to pay principal of or interest on particular Securities.

           When any of the Trustee,  the Paying Agent and the  Registrar  incurs
expenses  or renders  services  after an Event of Default  specified  in Section
6.1(f) or (g) occurs,  the  expenses and the  compensation  for the services are
intended to constitute expenses of administration  under any Bankruptcy Law. The
provisions of the Section shall survive the termination of this Indenture.

           SECTION 7.8      Replacement of Trustee.
                            -----------------------

           The  Trustee  may resign at any time by so  notifying  the Company in
writing,  such  resignation to be effective upon the  appointment of a successor
Trustee.  The  Holders  of a majority  in  principal  amount of the  outstanding
Securities may remove the Trustee by so notifying the Trustee in writing and may
appoint a successor  Trustee with the Company's  consent which consent shall not
be unreasonably withheld. The Company may remove the Trustee if:

                      (a) the Trustee fails to comply with Section 7.10;

                      (b) the Trustee is adjudged a bankrupt or an insolvent;

                      (c) a receiver or other public officer takes charge of the
           Trustee or its property; or

                      (d) the Trustee becomes incapable of acting.

           If the  Trustee  resigns or is removed or if a vacancy  exists in the
office of Trustee  for any reason (the  Trustee in such event being  referred to
herein as the retiring Trustee),


<PAGE>

                                      -85-

the Company shall promptly  appoint a successor  Trustee.  Within one year after
the  successor  Trustee  takes  office,  the Holders of a majority in  principal
amount of the  Securities  may  appoint  a  successor  Trustee  to  replace  the
successor Trustee appointed by the Company.

           A  successor  Trustee  shall  deliver  a  written  acceptance  of its
appointment to the retiring Trustee and to the Company.  Immediately after that,
the retiring  Trustee  shall  transfer all property held by it as Trustee to the
successor Trustee (subject to the lien provided in Section 7.7), the resignation
or removal of the retiring  Trustee  shall become  effective,  and the successor
Trustee  shall have all the rights,  powers and duties of the Trustee under this
Indenture.  A  successor  Trustee  shall mail notice of its  succession  to each
Securityholder.

           If a successor  Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holders of at least 25% in principal amount of then  outstanding  Securities may
petition, at the expense of the Company, any court of competent jurisdiction for
the appointment of a successor Trustee.

           If the Trustee fails to comply with Section 7.10, any  Securityholder
may petition any court of competent  jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

           Notwithstanding  replacement of the Trustee  pursuant to this Section
7.8, the Company's  obligations under Section 7.7 shall continue for the benefit
of the retiring Trustee.

           SECTION 7.9      Successor Trustee by Merger, Etc.
                            ---------------------------------

           If the  Trustee  consolidates  with,  merges  or  converts  into,  or
transfers all or  substantially  all of its corporate trust business to, another
corporation  or  national  banking  association,  the  resulting,  surviving  or
transferee  corporation or national banking  association without any further act
shall be the successor  Trustee,  provided such  corporation or national banking
association shall be otherwise qualified and eligible under this Article VII.

           SECTION 7.10     Eligibility; Disqualification.
                            ------------------------------

           This  Indenture  shall  always  have  a  Trustee  who  satisfies  the
requirements of TIA ss. 310(a)(1) and (2). There shall


<PAGE>

                                      -86-

at all times be a Trustee  hereunder  which  shall be a Person  that is eligible
pursuant  to the TIA to act as such and has  combined  capital and surplus of at
least  $150,000,000.  If such Person  publishes  reports of  condition  at least
annually, pursuant to law or to the requirements of any supervising or examining
authority,  then for the  purposes of this  Section,  the  combined  capital and
surplus of such person shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. The Trustee shall
comply with TIA ss.  310(b),  provided  that there  shall be  excluded  from the
operation of TIA ss.  310(b)(1) any  indenture or  indentures  under which other
securities, or certificates of interest or participation in other securities, of
the Company are outstanding if the  requirements for such exclusion set forth in
TIA ss.  310(b)(1)  are met.  The  provisions  of TIA ss. 310 shall apply to the
Company, as obligor of the Securities.

           SECTION 7.11      Preferential Collection of Claims Against
                             Company.
                             --------

           The Trustee shall comply with TIA ss. 311(a),  excluding any creditor
relationship  listed in TIA ss.  311(b).  A  Trustee  who has  resigned  or been
removed shall be subject to TIA ss. 311(a) to the extent indicated therein.  The
provisions  of TIA  ss.  311  shall  apply  to the  Company  as  obligor  on the
Securities.

            SATISFACTION AND DISCHARGE OF INDENTURE; UNCLAIMED MONEYS


           SECTION 8.1.     Satisfaction and Discharge of
                            Indenture.
                            ----------

           If at any time (a) the  Company  shall have paid or caused to be paid
the  principal of and  interest on all the  Securities  of a Series  outstanding
hereunder (other than Securities  which have been destroyed,  lost or stolen and
which have been  replaced or paid as  provided  in Section  2.7) as and when the
same shall have become due and payable,  or (b) the Company shall have delivered
to the Trustee  for  cancellation  all  Securities  of such  Series  theretofore
authenticated  (other than any  Securities  of such Series which shall have been
destroyed, lost or stolen and which shall have been replaced or paid as provided
in  Section  2.7) or (c) (i) all the  Securities  of a  Series  not  theretofore
delivered to the Trustee for cancellation shall 


<PAGE>

                                      -87-

have  become due and  payable,  or are by their  terms to become due and payable
within  one year or are to be  called  for  redemption  within  one  year  under
arrangements satisfactory to the Trustee for the giving of notice of redemption,
and (ii) the Company shall have irrevocably  deposited or caused to be deposited
with the  Trustee as trust  funds the entire  amount in cash  (other than moneys
repaid by the  Trustee or any paying  agent to the  Company in  accordance  with
Section  8.4) or U.S.  Government  Obligations,  maturing  as to  principal  and
interest in such  amounts and at such times as will insure the  availability  of
cash  sufficient to pay at maturity or upon  redemption  all  Securities of such
Series  (other  than  those  Securities  of such  Series  which  shall have been
destroyed, lost or stolen and which shall have been replaced or paid as provided
in Section  2.7) not  theretofore  delivered  to the Trustee  for  cancellation,
including  principal  and interest due or to become due on or prior to such date
of maturity as the case may be, and if, in any such case, the Company shall also
pay or cause to be paid all other sums  payable  hereunder  by the Company  with
respect to Securities,  then this Indenture  shall cease to be of further effect
with  respect  to  Securities  of  such  Series  (except  as to  (i)  rights  of
registration  of transfer and  exchange of  Securities  of such Series,  and the
Company's right of optional redemption,  if any, (ii) substitution of mutilated,
defaced,  destroyed,  lost or stolen Securities of such Series,  (iii) rights of
holders to receive payments of principal thereof and interest thereon,  upon the
original stated due dates therefor (but not upon acceleration), (iv) the rights,
obligations  and  immunities of the Trustee  hereunder and (v) the rights of the
Security  holders  as  beneficiaries  hereof  with  respect to the  property  so
deposited with the Trustee  payable to all or any of them,  and the Trustee,  on
demand of the Company accompanied by an Officers'  Certificate and an Opinion of
Counsel  and at the  cost and  expense  of the  Company,  shall  execute  proper
instruments  acknowledging  such  satisfaction of and discharging this Indenture
with respect to Securities of such Series;  provided, that the rights of Holders
of the  Securities of such Series to receive  amounts in respect of principal of
and interest on the  Securities of such Series held by them shall not be delayed
longer  than  required  by  then-applicable  mandatory  rules or policies of any
securities  exchange upon which the Securities are listed. The Company agrees to
reimburse  the  Trustee  for any costs or  expenses  thereafter  reasonably  and
properly  incurred and to  compensate  the Trustee for any  services  thereafter
reasonably  and  properly  rendered  by the  Trustee  in  connection  with  this
Indenture or the Securities.

           Subject to Section 8.4 and to the subordination provisions of Article
XI hereof,  all moneys  deposited with the Trustee pursuant to Section 8.1 shall
be held in trust and applied by it to the  payment,  either  directly or through
any paying agent (including the Company acting as its own paying agent),  to the
Holders  of the  particular  Securities  of  such  Series  for  the  payment  or
redemption  of which such moneys have been  deposited  with the Trustee,  of all
sums due and to become due thereon for principal  and  interest;  but such money
need not be segregated from other funds except to the extent required by law.

           In connection with the  satisfaction  and discharge of this Indenture
with respect to the  Securities of a Series,  all moneys then held by any Paying
Agent under the  provisions of this  Indenture with respect to the Securities of
such Series  shall,  upon demand of the Company,  be repaid to it or paid to the
Trustee  and  thereupon  such paying  agent  shall be released  from all further
liability with respect to such moneys.

           SECTION 8.4.     Return of Moneys Held by Trustee and
                            Paying Agent Unclaimed for Two Years.
                            -------------------------------------

           Any moneys  deposited with or paid to the Trustee or any Paying Agent
for the payment of the  principal of or interest on any Security and not applied
but remaining  unclaimed for two years after the date upon which such  principal
or interest shall have become due and payable,  shall,  upon the written request
of the  Company  and  unless  otherwise  required  by  mandatory  provisions  of
applicable  escheat or  abandoned or  unclaimed  property  law, be repaid to the
Company by the  Trustee or such  Paying  Agent,  and the Holder of the  Security
shall,  unless otherwise required by mandatory  provisions of applicable escheat
or abandoned or unclaimed property laws, thereafter look only to the Company for
any payment  which such Holder may be entitled to collect,  and all liability of
the  Trustee or any Paying  Agent with  respect to such moneys  shall  thereupon
cease.

rities of any Series,  on the 123rd day after the deposit  referred to in clause

same),  except as to: (a) rights of registration  of transfer and exchange,  and
the  Company's  right of optional  redemption,  (b)  substitution  of apparently

deposited  with the  Trustee  payable to all or any of them;  provided  that the
following conditions shall have been satisfied:

                      (A) with  reference  to this  provision  the  Company  has
           deposited or caused to be irrevocably  deposited with the Trustee (or
           another trustee satisfying the requirements of Sections 7.8 and 7.10)
           as trust funds in trust,  specifically  pledged as security  for, and
           dedicated  solely to, the benefit of the Holders of the Securities of
           such  Series,  (i)  money  in an  amount,  or  (ii)  U.S.  Government
           Obligations  which  through the payment of interest and  principal in
           respect thereof in accordance with their terms will provide not later
           than one day before the due date of any  payment  referred to in this
           clause  (A)  money  in an  amount,  or (iii) a  combination  thereof,
           sufficient,  in  the  opinion  of a  nationally  recognized  firm  of
           independent public accountants  expressed in a written  certification
           thereof  delivered  to the  Trustee,  to pay  and  discharge  without
           consideration  of the reinvestment of such interest and after payment
           of  all  federal,   state  and  local  taxes  or  other  charges  and
           assessments in respect  thereof  payable by the Trustee the principal
           of,  premium,  if  any,  and  each  installment  of  interest  on the

                      (B) the  Company has  delivered  to the Trustee (i) either

           such  Series  will not  recognize  income,  gain or loss for  federal
           income tax  purposes  as a result of the  Company's  exercise  of its
           option under this  Section 8.5 and will be subject to federal  income
           tax on the same  amount and in the same  manner and at the same times

           would have been the case if such  deposit,  defeasance  and discharge
           had not  occurred,  which  Opinion  of  Counsel  must be based upon a
           ruling of the Internal Revenue Service to the same effect or a change
           in applicable federal income tax law or related treasury  regulations
           after  the date of this  Indenture  or (y) a ruling  directed  to the
           Trustee received from the Internal Revenue Service to the same effect
           as the  aforementioned  Opinion  of  Counsel  and (ii) an  Opinion of
           Counsel to the effect that the creation of the defeasance  trust does
           not violate the Investment  Company Act of 1940 and after the passage
           of 123 days following the deposit, the trust fund will not be subject
           to the effect of Section 547 of the U.S.  Bankruptcy  Code or Section
           15 of the New York Debtor and Creditor Law;

                      (C)  immediately  after giving effect to such deposit on a
           pro forma basis, no Event of Default,  or event that after the giving
           of notice or lapse of time or both would  become an Event of Default,
           shall have  occurred and be continuing on the date of such deposit or
           during  the  period  ending  on the  123rd day after the date of such
           deposit,  and such deposit  shall not result in a breach or violation
           of, or constitute a default under,  any other agreement or instrument
           to which the Company is a party or by which the Company is bound;

                      (D) the Company is not prohibited  from making payments in
           respect of the Securities by Article XI hereof; and

                      (E) if at such  time the  Securities  of such  Series  are
           listed on a national securities  exchange,  the Company has delivered
           to the  Trustee  an  Opinion  of  Counsel  to  the  effect  that  the
           Securities  of such  Series  will not be delisted as a result of such
           deposit, defeasance and discharge.

           SECTION 8.6      Defeasance of Certain Obligations.
                            ----------------------------------

           The Company may omit to comply with any term,  provision or condition
set forth in, and this  Indenture  will no longer be in effect with  respect to,
any  covenant in Article V or Sections  4.5 through 4.15 and clauses (c) and (e)
of Section 6.1 shall not be deemed to be an Event of Default with respect to the
Securities of a Series, if

                      (A) with  reference  to this  Section 8.6, the Company has
           deposited or caused to be irrevocably  deposited with

           the  Trustee (or  another  trustee  satisfying  the  requirements  of
           Section  7.8) as  trust  funds  in  trust,  specifically  pledged  as
           security for, and dedicated  solely to, the benefit of the Holders of

           Securities  of such  Series,  (i)  money in an  amount  or (ii)  U.S.
           Government  Obligations  which  through the  payment of interest  and
           principal  in respect  thereof in  accordance  with their  terms will
           provide  not  later  than one day  before  the due dates  thereof  or
           earlier  redemption   (irrevocably   provided  for  under  agreements
           satisfactory  to the  Trustee),  as the case may be,  of any  payment
           referred  to in this  clause  (A)  money  in an  amount,  or  (iii) a
           combination  thereof,  sufficient,  in the  opinion  of a  nationally
           recognized  firm of  independent  public  accountants  expressed in a
           written  certification  thereof delivered to the Trustee,  to pay and
           discharge without  consideration of the reinvestment of such interest
           and after  payment  of all  federal,  state and local  taxes or other
           charges and assessments in respect thereof payable by the Trustee the
           principal of,  premium,  if any, and each  installment of interest on

           earlier  redemption  (irrevocably  provided  for  under  arrangements
           satisfactory to the Trustee), as the case may be;

                      (B)  the  Company  has  delivered  to the  Trustee  (i) an
           Opinion of Counsel to the effect that Holders of  Securities  of such
           Series will not recognize income, gain or loss for federal income tax
           purposes as a result of the  Company's  exercise of its option  under
           this  Section  8.6 and will be subject  to federal  income tax on the
           same  amount  and in the same  manner  and at the same times as would
           have been the case if such  deposit and  defeasance  had not occurred
           and (ii) an Opinion of Counsel to the effect that the creation of the
           defeasance trust does not violate the Investment  Company Act of 1940
           and after the passage of 123 days  following  the deposit,  the trust
           fund will not be subject  to the  effect of  Section  547 of the U.S.
           Bankruptcy  Code or  Section 15 of the New York  Debtor and  Creditor
           Law;

                  (C)  immediately  after giving effect to such deposit on a pro
         forma  basis,  no Event of  Default,  or event that after the giving of
         notice or lapse of time or both would become an Event of Default, shall
         have  occurred and be  continuing on the date of such deposit or during
         the period ending on the 123rd day after the date of such de-

           posit, and such deposit shall not result in a breach or violation of,
           or constitute a default under,  any other  agreement or instrument to
           which the Company is a party or by which the Company is bound;

                      (D) the Company is not prohibited  from making payments in
           respect of the Securities by Article XI hereof; and

                      (E)  if at  such  time  the  Securities  are  listed  on a
           national  securities  exchange,  the  Company  has  delivered  to the
           Trustee an Opinion of Counsel to the effect that the Securities  will
           not  be  delisted  as  a  result  of  such  deposit,  defeasance  and
           discharge.

           SECTION 8.7      Reinstatement.
                            --------------

           If the Trustee or Paying  Agent is unable to apply any monies or U.S.
Government  Obligations in accordance with Article 8 with respect to a Series of
Securities  by  reason  of any  legal  proceeding  or by  reason of any order or
judgment  of any  court or  governmental  authority  enjoining,  restraining  or
otherwise  prohibiting such  application,  the Company's  obligations under this
Indenture  and such  Series of  Securities  shall be revived and  reinstated  as
though no deposit had occurred  pursuant to this Article  until such time as the
Trustee or Paying Agent is permitted to apply all such monies or U.S. Government
Obligations in accordance with this Article VIII; provided, however, that if the
Company has made any  payment of  principal  of or  interest  on any  Securities
because of the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Securities to receive such payment from the
monies or U.S. Government Obligations held by the Trustee or Paying Agent.

                            ---------------------------

           Without the consent of any Holders,  the Company,  when authorized by
resolutions of its Board of Directors (copies of which shall be delivered to the
Trustee) and the Trustee may amend,  waive or supplement  this  Indenture or the
Securities


<PAGE>

                                      -93-

without notice to or consent of any Holder for any of the following purposes:

                      (a) to cure any ambiguity,  defect or inconsistency in the
           Indenture,  provided  that  such  amendments  or  supplements  do not
           adversely  affect  the  interests  of the  Holders  in  any  material
           respect;

                      (b) to provide for  uncertificated  Securities in addition
           to or in place of certificated Securities;

                      (c) to comply with any  requirements  of the SEC under the
           TIA;

                      (d) to evidence the succession in accordance  with Article
           V hereof of another  Person to the Company and the  assumption by any
           such  successor  of the  covenants  of the Company  herein and in the
           Securities;

                      (e)  to  evidence  and  provide  for  the   acceptance  of
           appointment hereunder by a separate or successor Trustee with respect
           to the Securities; or

                      (f) to make any other change that does not  materially and
           adversely affect the rights of any Holder;

provided,  however,  that in making  such  change,  the Trustee may rely upon an
Opinion of Counsel stating that such change does not adversely affect the rights
of any Holder.

           SECTION 9.2      With Consent of Holders.
                            ------------------------

           Subject to Section 6.7 and the  provisions  of this  Section 9.2, the
Company,  when  authorized by  resolution  of its Board of Directors  (copies of
which shall be delivered to the Trustee) and the Trustee may amend or supplement
this  Indenture,  the Securities  with the written  consent of the Holders of at
least a majority in principal amount of the Securities then outstanding. Subject
to Section 6.7 and the  provisions  of this  Section 9.2, the Holders of, in the
aggregate,  at least a  majority  in  principal  amount of the then  outstanding
Securities  affected may waive  compliance  by the Company with any provision of
this  Indenture,  the  Securities  without  notice to any other  Securityholder.
However,  without the consent of each  Securityholder  affected,  an  amendment,
supplement or waiver, including a waiver pursuant to Section 6.4, may not:


<PAGE>

                                      -94-

                      (a) reduce the principal  amount of Securities the Holders
           of which must consent to an  amendment,  supplement  or waiver of any
           provision of or with respect to this Indenture or the Securities; or

                      (b) reduce the principal  amount of,  premium,  if any, or
           interest, on any Security; or

                      (c) change the Stated  Maturity of or any  installment  of
           interest on, any Security; or

                      (d) make the  principal  of, or interest  on, any Security
           payable in money other than as provided herein, or

                      (e) make any change in  provisions  relating to waivers of
           defaults,  the ability of Holders to enforce  their rights under this
           Indenture or in the matters discussed in clauses (a) through (h); or

                      (f) adversely  affect the ranking of the  Securities  this
           Indenture.

           It shall not be necessary  for the consent of the Holders  under this
Section 9.2 to approve the particular form of any proposed amendment, supplement
or waiver,  but it shall be  sufficient  if such consent  approves the substance
thereof.

           After an  amendment,  supplement  or waiver  under this  Section  9.2
becomes  effective,  the Company  shall mail to the Holders  affected  thereby a
notice briefly  describing the amendment,  supplement or waiver.  Any failure of
the Company to mail such notice, or any defect therein,  shall not, however,  in
any way  impair or  affect  the  validity  of any such  supplemental  indenture.
Notwithstanding  the foregoing,  no amendment shall modify any provision of this
Indenture  so as to  affect  adversely  the  rights  of  any  holder  of  Senior
Indebtedness of the Company or Guarantor Senior  Indebtedness to the benefits of
the  subordination  provisions under this Indenture  without the consent of such
holder.

           SECTION 9.3      Compliance with Trust Indenture Act.
                            ------------------------------------

           Every  amendment to or supplement of this Indenture or the Securities
shall be set forth in a  supplemental  indenture  that  complies with the TIA as
then in effect.


<PAGE>

                                      -95-

           SECTION 9.4      Revocation and Effect of Consents.
                            ----------------------------------

           Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder is a  continuing  consent by the  Holder and every  subsequent
Holder of that Security or portion of that Security that evidences the same debt
as the consenting Holder's Security, even if notation of the consent is not made
on any Security.  However,  any such Holder or subsequent  Holder may revoke the
consent as to his Security or portion of a Security.  Such  revocation  shall be
effective only if the Trustee receives the notice of revocation  before the date
the  amendment,  supplement or waiver  becomes  effective.  Notwithstanding  the
above,  nothing in this paragraph  shall impair the right of any  Securityholder
under ss. 316(b) of the TIA.

           The Company may, but shall not be obligated to, fix a record date for
the purpose of  determining  the Holders  entitled to consent to any  amendment,
supplement  or waiver  which  record date shall be at least 10 days prior to the
first   solicitation  of  such  consent.   If  a  record  date  is  fixed,  then
notwithstanding  the second and third  sentences  of the  immediately  preceding
paragraph,  those  Persons  who were  Holders at such record date (or their duly
designated  proxies),  and only those  Persons,  shall be entitled to consent to
such amendment,  supplement or waiver or to revoke any consent previously given,
whether or not such Persons  continue to be Holders after such record date. Such
consent  shall be  effective  only for actions  taken  within 90 days after such
record date.

           After an amendment,  supplement or waiver becomes effective, it shall
bind every  Securityholder  unless it makes a change described in any of clauses
(a) through (h) of Section 9.2. In that case the amendment, supplement or waiver
shall bind each Holder of a Security who has consented to it.

           SECTION 9.5      Notation on or Exchange of Securities.
                            -------------------------------------

           If  an  amendment,  supplement  or  waiver  changes  the  terms  of a
Security,  the Trustee shall (in accordance with the specific written  direction
of the Company) request the Holder of the Security to deliver it to the Trustee.
The Trustee  shall (in  accordance  with the specific  direction of the Company)
place an appropriate notation on the Security about the changed terms and return
it to the Holder.  Alternatively,  if the Company or the Trustee so  determines,
the  Company in exchange  for the  Security  shall  issue and the Trustee  shall
authenticate a new Secu-


<PAGE>

                                      -96-

rity that reflects the changed terms.  Failure to make the appropriate  notation
or issue a new  Security  shall  not  affect  the  validity  and  effect of such
amendment, supplement or waiver.

           SECTION 9.6      Trustee to Sign Amendments, Etc.
                            -------------------------------

           The Trustee shall sign any amendment, supplement or waiver authorized
pursuant  to this  Article IX if the  amendment,  supplement  or waiver does not
adversely  affect the rights,  duties or immunities of the Trustee.  If it does,
the Trustee may, but need not, sign it. In signing any amendment,  supplement or
waiver,  the Trustee shall be entitled to receive,  if  requested,  an indemnity
reasonably  satisfactory  to it and to receive,  and shall be fully protected in
relying upon, an Officers'  Certificate  and an Opinion of Counsel  stating that
the execution of any amendment, supplement or waiver authorized pursuant to this
Article IX is authorized or permitted by this  Indenture and that it constitutes
the legal,  valid and  binding  obligation  of the  Company  and  subject to the
customary exceptions.

                           SUBORDINATION OF SECURITIES


           SECTION 11.1       Agreement to Subordinate.
                              -------------------------

           The  Company  covenants  and agrees,  and each  Holder of  Securities
issued hereunder by his acceptance thereof likewise  covenants and agrees,  that
all Securities  shall be issued  subject to the provisions of this Article;  and
each person holding any Security,  whether upon original issue or upon transfer,
assignment  or exchange  thereof  accepts and agrees that the  Principal  of and
interest on all  Securities  issued  hereunder  shall,  to the extent and in the
manner  herein  set forth,  be  subordinated  and  subject in right to the prior

           SECTION 11.2       Payments to Securityholders.
                              ----------------------------

           No payments on account of Principal  of,  Change of Control  purchase
price,  or  interest  on the  Securities  shall  be made if at the  time of such
payment or  immediately  after giving effect thereto there shall exist a default
in any payment with respect to any Senior Debt,  and such event of default shall
not have been cured or waived or shall not have  ceased to exist.  In  addition,
during  the  continuance  of any other  event of default  (other  than a payment
default) with respect to  Designated  Senior Debt pursuant to which the maturity
thereof may be accelerated, from and after the date of receipt by the Trustee of
written notice from the holders of such Designated  Senior Debt or from an agent
of such holders, no payments on account of Principal, Change of Control purchase
price, or interest in respect of the Securities may be made by the Company for a
period ("Payment  Blockage  Period")  commencing on the date of delivery of such
notice and ending 179 days thereafter (unless such Payment Blockage Period shall
be  terminated  by  written  notice  to the  Trustee  from the  holders  of such
Designated  Senior  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  Securities 


<PAGE>

                                     -102-

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 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 Debt,  unless
such event of  default  shall have been cured or waived for a period of not less
than 90 consecutive days.

          Upon any payment or  distribution of assets of the Company of any kind
or character,  whether in cash,  property or  securities,  to creditors upon any
liquidation, dissolution, winding up, receivership,  reorganization,  assignment
for the  benefit of  creditors,  marshalling  of assets and  liabilities  or any
bankruptcy, insolvency or similar proceedings of the Company, all amounts due or
to become due upon all Senior Debt shall first be paid in full,  in cash or cash
equivalents,  or payment  thereof  provided  for in  accordance  with its terms,
before any  payment is made on account of the  Principal  of,  Change of Control
purchase price, or interest on the indebtedness evidenced by the Securities, and
upon   any   such   liquidation,    dissolution,   winding   up,   receivership,
reorganization,   assignment,   marshalling  or   proceeding,   any  payment  or
distribution of assets of the Company of any kind or character, whether in cash,
property or  securities,  to which the Holders of the  Securities or the Trustee
under this Indenture would be entitled,  except for the provisions hereof, shall
be paid by the Company or by any receiver,  trustee in  bankruptcy,  liquidating
trustee,  agent or other Person making such payment or  distribution,  or by the
Holders of the  Securities or by the Trustee under this Indenture if received by
them or it,  directly to the holders of Senior Debt (pro rata to such holders on
the basis of the  respective  amounts of Senior  Debt held by such  holders)  or
their  respective  representatives,  or to the  trustee  or  trustees  under any
indenture  pursuant to which any instruments  evidencing any of such Senior Debt
may have been issued,  as their respective  interests may appear,  to the extent
necessary to pay all Senior Debt in full (including,  without limitation, except
to the extent, if any, prohibited by mandatory provisions of law,  post-petition
interest,  in any such  proceedings),  after  giving  effect  to any  concurrent
payment or distribution to or for the holders of Senior Debt, before any payment
or  distribution  is made to the holders of the  indebtedness  evidenced  by the
Securities or to the Trustee under this Indenture.

          In the event  that,  notwithstanding  the  foregoing,  any  payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities,  prohibited 


<PAGE>

                                     -103-

by the  foregoing,  shall be received by the Trustee under this Indenture or the
holders of the Securities before all Senior Debt is paid in full or provision is
made for such payment in accordance with its terms, such payment or distribution
shall be held in trust for the benefit of and shall be paid over or delivered to
the holders of such Senior Debt or their respective  representatives,  or to the
trustee  or  trustees  under any  indenture  pursuant  to which any  instruments
evidencing  any of such Senior Debt may have been  issued,  as their  respective
interests  may  appear,  for  application  to the  payment  of all  Senior  Debt
remaining  unpaid  until all such  Senior  Debt  shall have been paid in full in
accordance  with its terms,  after giving  effect to any  concurrent  payment or
distribution to or for the holders of such Senior Debt.

          For  purposes  of  this  Article,   the  words,  "cash,   property  or
securities"  shall not be deemed to  include  shares of stock of the  Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided  for by a plan of  arrangement,  reorganization  or  readjustment,  the
payment  of which is  subordinated  (at  least to the  extent  provided  in this
Article with respect to the  Securities) to the payment of all Senior Debt which
may at the time be outstanding; provided, that (i) the Senior Debt is assumed by
the new corporation, if any, resulting from any such arrangement, reorganization
or readjustment,  and (ii) the rights of the holders of the Senior Debt are not,
without the consent of such holders, altered by such arrangement, reorganization
or  readjustment.  The  consolidation  of the Company with, or the merger of the
Company into,  another  corporation  or the  liquidation  or  dissolution of the
Company following the conveyance or transfer of its property as an entirety,  or
substantially  as an  entirety,  to  another  corporation  upon  the  terms  and
conditions provided in Article V shall not be deemed a dissolution,  winding-up,
liquidation  or  reorganization  for the  purposes of this Section if such other
corporation  shall,  as a part  of such  consolidation,  merger,  conveyance  or
transfer,  comply  with the  conditions  stated in  Article  V.  Nothing in this
Section  shall apply to claims of, or payments to, the Trustee under or pursuant
to Article VII, except as provided therein. This Section shall be subject to the
further provisions of Section 11.5.

          SECTION 11.3       Subrogation of Securities.
                             --------------------------

          Subject to the payment in full of all Senior Debt,  the holders of the
Securities  shall be  subrogated  to the rights of the holders of Senior Debt to
receive payments or distributions of cash, property or securities of the Company
applicable 


<PAGE>

                                     -104-

to the Senior Debt until the principal of and interest on the  Securities  shall
be paid in full;  and,  for the  purposes  of such  subrogation,  no payments or
distributions  to the  holders  of the  Senior  Debt of any  cash,  property  or
securities to which the holders of the Securities or the Trustee on their behalf
would be entitled except for the provisions of this Article, and no payment over
pursuant  to the  provisions  of this  Article to the  holders of Senior Debt by
holders of the  Securities or the Trustee on their behalf shall,  as between the
Company,  its creditors other than holders of Senior Debt and the holders of the
Securities,  be deemed to be a payment  by the  Company  to or on account of the
Senior Debt; and no payments or distributions of cash, property or securities to
or for the benefit of the Securityholders  pursuant to the subrogation provision
of this Article,  which would  otherwise have been paid to the holders of Senior
Debt shall be deemed to be a payment by the Company to or for the account of the
Securities.  It is  understood  that the  provisions of this Article are and are
intended  solely for the purpose of defining the relative  rights of the holders
of the  Securities,  on the one hand, and the holders of the Senior Debt, on the
other hand.

          Nothing contained in this Article or elsewhere in this Indenture or in
the  Securities  is intended to or shall  impair,  as between the  Company,  its
creditors  other  than the  holders  of  Senior  Debt,  and the  holders  of the
Securities,  the obligation of the Company, which is absolute and unconditional,
to pay to the holders of the  Securities  the  principal  of and interest on the
Securities as and when the same shall become due and payable in accordance  with
their  terms,  or is  intended  to or shall  affect the  relative  rights of the
holders of the Securities and creditors of the Company other than the holders of
the Senior Debt, nor shall anything  herein or therein prevent the holder of any
Security or the Trustee on his behalf from  exercising  all  remedies  otherwise
permitted by applicable  law upon default under this  Indenture,  subject to the
rights,  if any,  under this Article of the holders of Senior Debt in respect of
cash,  property or securities  of the Company  received upon the exercise of any
such remedy.

          Upon any payment or distribution of assets of the Company  referred to
in this Article, the Trustee, subject to the provisions of Sections 7.1 and 7.2,
and the  holders of the  Securities  shall be entitled to rely upon any order or
decree made by any court of competent  jurisdiction  in which such  liquidation,
dissolution, winding up, receivership, reorganization, assignment or marshalling
proceedings  are  pending,  or  a  certificate  of  the  receiver,   trustee  in
bankruptcy,  liquidating 


<PAGE>

                                     -105-

trustee, agent or other person making such payment or distribution, delivered to
the Trustee or to the holders of the Securities, for the purpose of ascertaining
the persons  entitled to  participate in such  distribution,  the holders of the
Senior Debt and other indebtedness of the Company, the amount thereof or payable
thereon,  the amount or amounts paid or distributed  thereon and all other facts
pertinent thereto or to this Article.

          SECTION 11.4       Authorization by Securityholders.
                             ---------------------------------

          Each holder of a Security by his  acceptance  thereof  authorizes  the
Trustee in his behalf to take such action as may be necessary or  appropriate to
effectuate the  subordination  provided in this Article and appoints the Trustee
his attorney-in-fact for any and all such purposes.

          SECTION 11.5       Notice to Trustee.
                             ------------------

          The Company shall give prompt written notice to the Trustee and to any
Paying Agent of any fact known to the Company which would prohibit the making of
any payment of moneys to or by the Trustee or any Paying Agent in respect of the
Securities pursuant to the provisions of this Article. Regardless of anything to
the contrary  contained in this  Article or  elsewhere  in this  Indenture,  the
Trustee shall not be charged with  knowledge of the existence of any Senior Debt
or of any default or event of default  with respect to any Senior Debt or of any
other facts which  would  prohibit  the making of any payment of moneys to or by
the Trustee,  unless and until the Trustee shall have received notice in writing
at its principal  Corporate  Trust Office to that effect signed by an officer of
the  Company,  or by a holder or agent of a holder of Senior Debt who shall have
been  certified  by the  Company  or  otherwise  established  to the  reasonable
satisfaction  of the Trustee to be such holder or agent, or by the trustee under
any indenture pursuant to which Senior Debt shall be outstanding,  and, prior to
the receipt of any such written notice,  the Trustee shall,  subject to Sections
7.1 and 7.2, be entitled to assume that no such facts exist; provided that if on
a date at least  three  Business  Days prior to the date upon which by the terms
hereof any such moneys shall become payable for any purpose (including,  without
limitation,  the payment of the  principal  of, or interest on any Security) the
Trustee shall not have received with respect to such moneys the notice  provided
for in this Section,  then,  regardless of anything herein to the contrary,  the
Trustee  shall have full power and authority to receive such moneys and to apply
the same to the purpose for which they were received,  and


<PAGE>

                                     -106-

shall not be affected by any notice to the contrary  which may be received by it
on or after such prior date.

          Regardless of anything to the contrary  herein,  nothing shall prevent
(a) any payment by the Company or the Trustee to the  Securityholders of amounts
in connection  with a redemption of Securities if (i) notice of such  redemption
has been given  pursuant  to Article  III prior to the receipt by the Trustee of
written  notice as  aforesaid,  and (ii) such notice of  redemption is given not
earlier  than 60 days  before the  redemption  date,  or (b) any  payment by the
Trustee to the  Securityholders of amounts deposited with it pursuant to Section
8.1.

          The  Trustee  shall be  entitled  to rely on the  delivery  to it of a
written  notice by a person  representing  himself to be a holder of Senior Debt
(or a trustee on behalf of such holder) to  establish  that such notice has been
given by a holder of Senior Debt or a trustee on behalf of any such  holder.  In
the event that the Trustee  determines  in good faith that  further  evidence is
required  with  respect to the right of any person as a holder of Senior Debt to
participate in any payment or distribution pursuant to this Article, the Trustee
may request such person to furnish  evidence to the reasonable  satisfaction  of
the Trustee as to the amount of Senior Debt held by such  person,  the extent to
which such person is entitled to participate in such payment or distribution and
any other facts  pertinent to the rights of such person under this Article,  and
if such  evidence  is not  furnished  the  Trustee may defer any payment to such
person pending judicial  determination as to the right of such person to receive
such payment.

          SECTION 11.6       Trustee's Relation to Senior Debt.
                             ----------------------------------

          The  Trustee  and any agent of the  Company  or the  Trustee  shall be
entitled to all the rights set forth in this  Article with respect to any Senior
Debt which may at any time be held by it in its individual or any other capacity
to the same  extent as any  other  holder of  Senior  Debt and  nothing  in this
Indenture  shall deprive the Trustee or any such agent,  of any of its rights as
such holder.  Nothing in this Article  shall apply to claims of, or payments to,
the Trustee under or pursuant to Section 7.7.

                  With  respect  to the  holders  of Senior  Debt,  the  Trustee
undertakes to perform or to observe only such of its  covenants and  obligations
as are  specifically  set forth in this  Article,  and no implied  covenants  or
obligations  with  respect to the holders of Senior Debt shall be read into this
Indenture  


<PAGE>

                                     -107-

against the Trustee.  The Trustee shall not be deemed to owe any fiduciary  duty
to the holders of Senior Debt and, subject to the provisions of Sections 7.1 and
7.2,  the  Trustee  shall not be liable to any holder of Senior Debt if it shall
pay over or deliver to holders of  Securities,  the Company or any other  person
moneys or assets to which any holder of Senior  Debt shall be entitled by virtue
of this Article or otherwise.

          SECTION 11.7 No Impairment of Subordination.
          --------------------------------------------

          No right of any present or future holder of any Senior Debt to enforce
subordination  as herein  provided shall at any time in any way be prejudiced or
impaired  by any act or failure to act on the part of the  Company or by any act
or failure to act, in good faith, by any such holder, or by any noncompliance by
the  Company  with  the  terms,  provisions  and  covenants  of this  Indenture,
regardless of any knowledge  thereof which any such holder may have or otherwise
be charged with.

          1.  Interest.  THE  AES  CORPORATION,   a  Delaware  corporation  (the
"Company," which  definition  shall include any successor  thereto in accordance
with the Indenture  (as defined  below)),  promises to pay,  until the principal
hereof is paid or made available for payment,  interest on the principal  amount
set forth on the reverse  side hereof at a rate of 8.50% per annum.  Interest on
the Notes will accrue from and including the most recent date to which  interest

payable in arrears on May 1,and November 1, and at the stated  maturity (each an

(except defaulted  interest) to the Persons who are registered  Holders of Notes
at the close of business on April 15 and October 15 next  preceding the Interest
Payment  Date.  Holders  must  surrender  Notes  to a Paying  Agent  to  collect
principal  payments.  The  Company  will pay  principal,  premium,  if any,  and
interest  in money of the  United  States  that at the time of  payment is legal
tender  for  payment of public  and  private  debts.  At the  Company's  option,
interest may be paid by check mailed to the registered  address of the Holder of
this Note.

<PAGE>


those made part of the Indenture by reference to the Trust Indenture Act of 1939
(15 U.S. Code ss.ss.  77aaa-77bbbb)  as amended from time to time. The Notes are
subject to all such terms, and Securityholders are referred to the Indenture and
such  Act for a  statement  of  them.  Capitalized  terms  used  herein  and not
otherwise  defined have the meanings set forth in the  Indenture.  The Notes are

             Year                           Price
             ----                         ---------
             2002                         104.250%

consummates  one or more offerings of its Qualified  Capital Stock,  the Company
may at its option,  use all or a portion of the proceeds  therefrom to redeem up
to 33% of the original aggregate  principal amount at maturity of the Notes at a
cash redemption  price equal to 108.500% of the principal  amount thereof,  plus
accrued and unpaid  interest  thereon  through the date of repurchase;  provided

<PAGE>


million  of  the  original  aggregate  principal  amount  of the  Notes  remains
outstanding thereafter.

          6. Offers to Purchase. Section 4.11 of the Indenture provides upon the
occurrence of a Change of Control and subject to further  limitations  contained
therein,  the  Company  shall  make an  offer  to  purchase  the  Securities  in
accordance with the procedures set forth in the Indenture.

          7. Denominations, Transfer, Exchange. The Securities are in registered
form  without  coupons in  denominations  of $1,000 and  integral  multiples  of
$1,000.  A Holder may transfer or exchange  Securities  in  accordance  with the
Indenture.  The Registrar may require a Holder,  among other things,  to furnish
appropriate  endorsements and transfer  documents and to pay to it any taxes and
fees  required by law or  permitted by the  Indenture.  The  Registrar  need not
transfer  or  exchange  any  Security  or  portion of a  Security  selected  for
redemption,  or  transfer  or exchange  any  Securities  for a period of 15 days
before the mailing of a notice of redemption of Securities to be redeemed.

          8. Persons Deemed Owners.  The registered  holder of a Security may be
treated as the owner of it for all purposes.

          9. Unclaimed  Money. If money for the payment of principal or interest
remains  unclaimed for two years, the Trustee or Paying Agent will pay the money
back to the Company at its written request.  After that, Holders entitled to the
money  must look to the  Company  for  payment as  general  creditors  unless an
"abandoned property" law designates another Person.

          10. Amendment,  Supplement,  Waiver.  The Company and the Trustee may,
without the consent of the holders of any outstanding  Securities,  amend, waive
or supplement the Indenture,  the  Securities  for certain  specified  purposes,
including,  among other things, curing ambiguities,  defects or inconsistencies,
maintaining the  qualification of the Indenture under the Trust Indenture Act of
1939 or making any other change that does not adversely affect the rights of any
Holder.  Other  amendments and  modifications of the Indenture or the Securities
may be made by the Company  and the  Trustee  with the consent of the Holders of
not less than a majority of the aggregate  principal  amount of the  outstanding
Securities,  subject to certain exceptions  requiring the consent of the Holders
of the particular Securities to be affected.

                                      A-4

<PAGE>


          11. Successor  Corporation.  When a successor  corporation assumes all
the  obligations of its  predecessor  under the Securities and the Indenture and
the  transaction  complies  with the terms of  Article V of the  Indenture,  the
predecessor  corporation,  subject to certain exceptions,  will be released from
those obligations.

          12.  Defaults  and  Remedies.  Events of Default  are set forth in the
Indenture.  Subject  to certain  limitations  in the  Indenture,  if an Event of
Default  (other than an Event of Default  specified in Section  6.1(f) or (g) of
the Indenture with respect to the Company)  occurs and is  continuing,  then the
holders of not less than 25% in aggregate  principal  amount of the  outstanding
Securities  (or in the case of an Event of Default  specified in Section 6.1 (a)
or (b) of the Indenture, the Holders of not less than 25% in aggregate principal
amount of the outstanding  Series so affected) may, or the Trustee may,  declare
the principal of, premium, if any, plus accrued interest,  if any, to be due and
payable  immediately.  If an Event of Default specified in Section 6.1(f) or (g)
of the  Indenture  with  respect to the Company  occurs and is  continuing,  the
principal of,  premium,  if any, and accrued  interest on all of the  Securities
shall ipso facto become and be immediately  due and payable subject to the prior
payment in full of Senior Debt without any  declaration or other act on the part
of the Trustee or any Holder.  Securityholders  may not enforce the Indenture or
the  Securities  except as  provided in the  Indenture.  The Trustee may require
indemnity reasonably  satisfactory to it before it enforces the Indenture or the
Securities.  Subject to certain limitations,  Holders of a majority in principal
amount of the then outstanding Securities may direct the Trustee in its exercise
of any trust or power. The Trustee may withhold from  Securityholders  notice of
any continuing  default (except a default in payment of principal or interest or
a failure to comply  with  Article V of the  Indenture)  if it  determines  that
withholding  notice is in their  interests.  The Company  must furnish an annual
compliance certificate to the Trustee.

          13. Trustee Dealings with Company.  The Trustee,  in its individual or
any other  capacity,  may make  loans to,  accept  deposits  from,  and  perform
services  for the Company or its  Affiliates,  and may  otherwise  deal with the
Company or its Affiliates, as if it were not Trustee.

          14.  No  Recourse  Against  Others.  A  director,  officer,  employee,
stockholder or beneficiary, as such, of the Company shall not have any liability
for any  obligations of the

                                      A-5

<PAGE>


Company  under the  Securities  or the  Indenture  or for any claim based on, in
respect  of  or  by  reason  of,  such  obligations  or  their  creation.   Each
Securityholder  by accepting a Security  waives and releases all such liability.
The  waiver  and  release  are part of the  consideration  for the  issue of the
Securities.

          15. Defeasance.  The Indenture  contains  provisions (which provisions
apply to this Note) for defeasance at any time of (a) the entire indebtedness of
the  Company or this Note and (b)  certain  restrictive  covenants  and  related
Defaults and Events of Default, in each case upon compliance by the Company with
certain conditions set forth therein.

          16.  Authentication.  This Note shall not be valid  until the  Trustee
signs the certificate of authentication on the other side of this Note.

          17. Abbreviations.  Customary abbreviations may be used in the name of
a Securityholder or an assignee,  such as: TEN COM (= tenants in common), TENANT
(=  tenants  by  the  entireties),  JT  TEN  (=  joint  tenants  with  right  of
survivorship and not as tenants in common),  CUST (= Custodian),  and U/G/M/A (=
Uniform Gifts to Minors Act).

          18. Subordination.  The Company's payment of principal of, premium, if
any, and interest on the Securities is subordinated in right of payment,  to the
extent and in the manner  provided in Article XI of the Indenture,  to the prior
payment  in  full  of  the  Senior  Debt  of the  Company.  Each  Holder  of the
Securities,  by his acceptance hereof, covenants and agrees that all payments of
the principal of, premium, if any, and interest on the Securities by the Company
shall be  subordinated  in accordance  with the  provisions of Article XI of the
Indenture, and each Holder accepts and agrees to be bound by such provisions.

          19.  GOVERNING  LAW. THE  INDENTURE AND THIS NOTE SHALL BE GOVERNED BY

REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

                                      B-2

<PAGE>


stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act of 1939 (15 U.S. Code ss.ss.  77aaa-77bbbb)  as amended from
time to time. The Debentures are subject to all such terms, and  Securityholders
are referred to the Indenture and such Act for a statement of them.  Capitalized
terms used herein and not  otherwise  defined have the meanings set forth in the
Indenture.  The  Debentures  are general  unsecured  obligations  of the Company
subordinated  in  right  of  payment  to all  Senior  Debt of the  Company.  The
Indenture  limits,  among  other  things,  the  ability of the  Company  and its
Restricted  Subsidiaries  to incur  certain  Debt;  pay dividends and make other
distributions; make certain investments; engage in unrelated businesses; dispose
of certain Assets;  engage in transactions  with certain  Affiliates;  and merge
with or into  another  entity.  The  limitations  are  subject  to a  number  of
important qualifications and exceptions.  The Company must report to the Trustee
annually  whether it is in  compliance  with the  limitations  contained  in the
Indenture.

          5. Optional Redemption.

The Debentures are subject to redemption  upon not less than 30 nor more than 60
days' notice by mail, at any time on or after November 1, 2004, as a whole or in
part, at the election of the Company, at a price equal to the sum of (i) 100% of
the principal  amount thereof plus accrued  interest to the Redemption Date plus
(ii) the Make-Whole Amount, if any.

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

The term "Reinvestment Rate" shall mean 0.50% (one-half of one percent) plus the
arithmetic  mean of the yields  under the  respective  headings  "This Week" and
"Last Week"  published in the  Statistical  Release under the caption  "Treasury
Constant   Maturities"   for  the  maturity   (rounded  to  the  nearest  month)
cor-

                                      B-3

<PAGE>


responding  to the  maturity  of the  principal  being  prepaid.  If no maturity
exactly  corresponds to such maturity,  yields for the two published  maturities
most closely  corresponding to such maturity shall be calculated pursuant to the
immediately  preceding  sentence and the Reinvestment Rate shall be interpolated
or extrapolated from such yields on a straight-line  basis,  rounding in each of
such relevant  periods to the nearest month.  For the purpose of calculating the
Reinvestment  Rate, the most recent  Statistical  Release published prior to the
date of determination of the Make-Whole Amount shall be used.

The term  "Statistical  Release" shall mean the statistical  release  designated
"H.15(519)"  or any  successor  publication  which is  published  weekly  by the
Federal  Reserve  System and which  establishes  yields on actively  traded U.S.
government  securities  adjusted to constant  maturities or, if such statistical
release is not published at the time of any  determination  under the Indenture,
then such other  reasonably  comparable  index which shall be  designated by the
Company.

          In addition  prior to November 1, 2000,  in the event that the Company
consummates  one or more offerings of its Qualified  Capital Stock,  the Company
may at its option,  use all or a portion of the proceeds  therefrom to redeem up
to 33% of the original aggregate principal amount at maturity of the Debenturess
at a cash  redemption  price equal to 108.875% of the principal  amount thereof,
plus  accrued  and  unpaid  interest  thereon  through  the date of  repurchase;
provided that at least $83.75 million of the original aggregate principal amount
of the Debentures remains outstanding thereafter.

          6. Sinking Fund.  The  Debentures are subject to a Sinking Fund in the
amount and manner set forth in the Indenture.

          7. Offers to Purchase. Section 4.11 of the Indenture provides upon the
occurrence of a Change of Control and subject to further  limitations  contained
therein,  the  Company  shall  make an  offer  to  purchase  the  Securities  in
accordance with the procedures set forth in the Indenture.

          8. Denominations, Transfer, Exchange. The Securities are in registered
form  without  coupons in  denominations  of $1,000 and  integral  multiples  of
$1,000.  A Holder may transfer or exchange  Securities  in  accordance  with the
Indenture.  The Registrar may require a Holder,  among other things,  to furnish
appropriate  endorsements and transfer  documents and to pay to 

                                      B-4

<PAGE>


it any  taxes  and fees  required  by law or  permitted  by the  Indenture.  The
Registrar  need not  transfer or exchange  any Security or portion of a Security
selected for redemption,  or transfer or exchange any Securities for a period of
15 days  before  the  mailing  of a notice of  redemption  of  Securities  to be
redeemed.

          9. Persons Deemed Owners.  The registered  holder of a Security may be
treated as the owner of it for all purposes.

          10. Unclaimed Money. If money for the payment of principal or interest
remains  unclaimed for two years, the Trustee or Paying Agent will pay the money
back to the Company at its written request.  After that, Holders entitled to the
money  must look to the  Company  for  payment as  general  creditors  unless an
"abandoned property" law designates another Person.

          11. Amendment,  Supplement,  Waiver.  The Company and the Trustee may,
without the consent of the holders of any outstanding  Securities,  amend, waive
or supplement the Indenture,  the  Securities  for certain  specified  purposes,
including,  among other things, curing ambiguities,  defects or inconsistencies,
maintaining the  qualification of the Indenture under the Trust Indenture Act of
1939 or making any other change that does not adversely affect the rights of any
Holder.  Other  amendments and  modifications of the Indenture or the Securities
may be made by the Company  and the  Trustee  with the consent of the Holders of
not less than a majority of the aggregate  principal  amount of the  outstanding
Securities,  subject to certain exceptions  requiring the consent of the Holders
of the particular Securities to be affected.

          12. Successor  Corporation.  When a successor  corporation assumes all
the  obligations of its  predecessor  under the Securities and the Indenture and
the  transaction  complies  with the terms of  Article V of the  Indenture,  the
predecessor  corporation,  subject to certain exceptions,  will be released from
those obligations.

          13.  Defaults  and  Remedies.  Events of Default  are set forth in the
Indenture.  Subject  to certain  limitations  in the  Indenture,  if an Event of
Default  (other than an Event of Default  specified in Section  6.1(f) or (g) of
the Indenture with respect to the Company)  occurs and is  continuing,  then the
holders of not less than 25% in aggregate  principal  amount of the  outstanding
Securities (or, in the case of an Event of Default  specified in Section 6.1 (a)
or (b) of the  Indenture,  the 

                                      B-5

<PAGE>


Holders  of  not  less  than  25%  of  the  aggregate  principal  amount  of the
outstanding  Series so affected) may, or the Trustee may,  declare the principal
of,  premium,  if any,  plus  accrued  interest,  if any,  to be due and payable
immediately.  If an Event of Default  specified in Section  6.1(f) or (g) of the
Indenture with respect to the Company  occurs and is  continuing,  the principal
of, premium,  if any, and accrued  interest on all of the Securities  shall ipso
facto become and be immediately  due and payable subject to the prior payment in
full of Senior  Debt  without  any  declaration  or other act on the part of the
Trustee or any Holder.  Securityholders  may not enforce  the  Indenture  or the
Securities  except  as  provided  in the  Indenture.  The  Trustee  may  require
indemnity reasonably  satisfactory to it before it enforces the Indenture or the
Securities.  Subject to certain limitations,  Holders of a majority in principal
amount of the then outstanding Securities may direct the Trustee in its exercise
of any trust or power. The Trustee may withhold from  Securityholders  notice of
any continuing  default (except a default in payment of principal or interest or
a failure to comply  with  Article V of the  Indenture)  if it  determines  that
withholding  notice is in their  interests.  The Company  must furnish an annual
compliance certificate to the Trustee.

          14. Trustee Dealings with Company.  The Trustee,  in its individual or
any other  capacity,  may make  loans to,  accept  deposits  from,  and  perform
services  for the Company or its  Affiliates,  and may  otherwise  deal with the
Company or its Affiliates, as if it were not Trustee.

          15.  No  Recourse  Against  Others.  A  director,  officer,  employee,
stockholder or beneficiary, as such, of the Company shall not have any liability
for any  obligations of the Company under the Securities or the Indenture or for
any claim  based on, in respect of or by reason of,  such  obligations  or their
creation.  Each  Securityholder  by accepting a Security waives and releases all
such  liability.  The waiver and release are part of the  consideration  for the
issue of the Securities.

          16. Defeasance.  The Indenture  contains  provisions (which provisions
apply  to  this  Debenture)  for  defeasance  at  any  time  of (a)  the  entire
indebtedness  of the  Company  or this  Debenture  and (b)  certain  restrictive
covenants  and  related  Defaults  and  Events  of  Default,  in each  case upon
compliance by the Company with certain conditions set forth therein.

          17.  Authentication.  This  Debenture  shall  not be valid  until  the
Trustee  signs the  certificate  of  authentication  on the  other  side of this
Debenture.

          18. Abbreviations.  Customary abbreviations may be used in the name of
a Securityholder or an assignee,  such as: TEN COM (= tenants in common), TENANT

survivorship and not as tenants in common),  CUST (= Custodian),  and U/G/M/A (=
Uniform Gifts to Minors Act).

          19. Subordination.  The Company's payment of principal of, premium, if
any, and interest on the Securities is subordinated in right of payment,  to the
extent and in the manner  provided in Article XI of the Indenture,  to the prior
payment  in  full  of  the  Senior  Debt  of the  Company.  Each  Holder  of the
Securities,  by his acceptance hereof, covenants and agrees that all payments of
the principal of, premium, if any, and interest on the Securities by the Company
shall be  subordinated  in accordance  with the  provisions of Article XI of the
Indenture, and each Holder accepts and agrees to be bound by such provisions.

     offer to exchange  (the  "Exchange  Offer") any and all of the  Registrable
     Securities for a like aggregate  principal amount of debt securities of the
     Company  which are  identical,  in the case of the Notes,  in all  material
     respects to the Notes and, in the case of the  Debentures,  in all material
     respects to the Debentures  (collectively,  the "Exchange Securities") (and
     which are entitled to the benefits of a trust  indenture which is identical
     in all material  respects to the Indenture  (other than such changes as are
     necessary to comply with any  requirements of the SEC to effect or maintain
     the qualification of such trust indenture under the TIA) and which has been
     qualified under the TIA),  except that the Exchange  Securities  shall have
     been registered pursuant to an effective  Registration  Statement under the
     Securities Act and shall contain no restrictive legend thereon. The Company
     agrees to use its  reasonable  best efforts to keep the Exchange Offer open
     for at least 20 business  days (or longer if required  by  applicable  law)
     after the date  notice of the  Exchange  Offer is mailed to Holders  and to
     consummate  the Exchange  Offer on or prior to the  Consummation  Date. The
     Exchange  Offer  will  be  registered  under  the  Securities  Act  on  the
     appropriate  form (the "Exchange  Registration  Statement") and will comply

     Act. If after such Exchange  Registration  Statement is initially  declared
     effective by the SEC,  the  Exchange  Offer or the issuance of the Exchange
     Securities  thereunder is interfered with by any stop order,  injunction or
     other order or requirement of the SEC or any other  governmental  agency or
     court  such  Exchange  Registration  Statement  shall be deemed not to have
     become   effective  for  purposes  of  this  Agreement.   Each  Holder  who

     Exchange  Securities received by it will be acquired in the ordinary course
     of its business, that at the time of the consummation of the Exchange Offer
     such Holder will have no  arrangement or  understanding  with any person to
     participate in the distribution of the Exchange  Securities in violation of
     the provisions of the Securities Act, and

                                       6


     that such Holder is not an affiliate  of the Company  within the meaning of
     the Securities  Act. Upon  consummation of the Exchange Offer in accordance
     with this Section 2, the  provisions of this  Agreement  shall  continue to
     apply,  mutatis,  mutandis,  solely with respect to Registrable  Securities
     that are  Private  Exchange  Securities  and  Exchange  Securities  held by
     Participating  Broker-Dealers,  and  the  Company  shall  have  no  further
     obligation to register Registrable  Securities (other than Private Exchange
     Securities and other than Exchange  Securities as to which clause (c)(1)(i)
     hereof  applies)  pursuant to Section 3 of this  Agreement.  No  securities
     other  than the  Exchange  Securities  shall be  included  in the  Exchange
     Registration Statement.

          (b) The Company shall include within the  Prospectus  contained in the
     Exchange   Registration   Statement  one  or  more  section(s)   reasonably
     acceptable  to the  Initial  Purchasers,  which  shall  contain  a  summary
     statement of the  positions  taken or policies made by the Staff of the SEC
     with respect to the  potential  "underwriter"  status of any  broker-dealer
     that is the  beneficial  owner (as defined in Rule 13d-3 under the Exchange
     Act) of Exchange  Securities received by such broker-dealer in the Exchange
     Offer (a "Participating Broker-Dealer"), whether such positions or policies
     have been publicly  disseminated  by the Staff of the SEC or such positions
     or  policies,  in  the  reasonable  judgment  of  the  Initial  Purchasers,
     represent the  prevailing  views of the Staff of the SEC.  Such  section(s)
     shall also allow the use of the  Prospectus  by all persons  subject to the
     prospectus  delivery  requirements  of the  Securities  Act,  including all
     Participating Broker-Dealers,  and include a statement describing the means
     by which Participating  Broker-Dealers may resell the Exchange  Securities.
     Each  participating  Broker-Dealer  will be required to acknowledge that it
     will  deliver a  Prospectus  in  connection  with any  resale  of  Exchange
     Securities.

          The Company shall use its reasonable best efforts to keep the Exchange
     Registration Statement effective and to amend and supplement the Prospectus
     contained  therein  in order  to  permit  such  Prospectus  to be  lawfully
     delivered by all persons subject to the prospectus delivery requirements of
     the Securities Act for such period of time as such persons must comply with
     such requirements in order to resell the Exchange Securities, provided that
     such  period  shall not exceed 90 days (or such  longer  period if

                                       7


     extended  pursuant  to the last  paragraph  of Section 5) (the  "Applicable
     Period").

          If, prior to consummation of the Exchange Offer, an Initial  Purchaser
     holds any  Securities  acquired  by it and  having  the status of an unsold
     allotment in the initial distribution, the Company upon the request of such
     Initial Purchaser shall, simultaneously with the delivery of the applicable
     Exchange  Securities in the Exchange Offer,  issue and deliver to each such
     Initial  Purchaser,  in exchange  (the  "Private  Exchange")  for the Notes
     and/or Debentures held by such Initial  Purchaser,  a like principal amount
     of debt  securities  of the  Company  that are  identical  in all  material
     respects to the  applicable  Exchange  Securities  (the  "Private  Exchange
     Securities")  (and which are issued  pursuant to the same  indenture as the
     Exchange  Securities)  except for the placement of a restrictive  legend on
     such Private Exchange  Securities.  The Private  Exchange  Securities shall
     bear the same CUSIP numbers as the respective Exchange Securities. Interest
     on the Exchange Securities and Private Exchange Securities will accrue from
     the last interest payment date on which interest was paid on the Securities
     surrendered  in exchange  therefor  or, if no interest has been paid on the
     Securities, from the Issue Date.

          Other  than as  provided  in the  Indenture  with  respect  to certain
     separate  voting  rights  for the  holders  of Notes  and  Debentures,  any
     indenture  under which the  Exchange  Securities  or the  Private  Exchange
     Securities  will be issued  shall  provide  that the  holders of any of the
     Exchange  Securities  and the  Private  Exchange  Securities  will vote and
     consent together on all matters (to which such holders are entitled to vote
     or  consent)  as one  class and that none of the  holders  of the  Exchange
     Securities and the Private Exchange  Securities will have the right to vote
     or  consent as a separate  class on any matter (to which such  holders  are
     entitled to vote or consent).

          (c) If (1)  prior  to the  consummation  of the  Exchange  Offer,  the
     Company  reasonably  determines  in good  faith  or  Holders  of at least a
     majority in aggregate principal amount of the Registrable Securities notify
     the Company that they have reasonably  determined in good faith that (i) in
     the opinion of counsel, the Exchange Securities would not, upon receipt, be
     tradeable by such  Holders who are not  affiliates  of the Company  without
     restriction under the Securities Act and without restrictions under ap-



<PAGE>
                                       8


     plicable  blue  sky or  state  securities  laws or (ii) in the  opinion  of
     counsel,  the SEC is unlikely to permit the  consummation  of the  Exchange
     Offer and/or (2) subsequent to the  consummation  of the Private  Exchange,
     holders of at least a majority in aggregate principal amount of the Private
     Exchange  Securities  so  request  with  respect  to the  Private  Exchange
     Securities  and/or (3) the Exchange Offer is commenced and not  consummated
     prior to the 45th day following the Consummation Date for any reason,  then
     the Company shall  promptly  deliver to the Holders and the Trustee  notice
     thereof (the "Shelf  Notice") and shall  thereafter  file an Initial  Shelf
     Registration  as set forth in  Section 3 (which  only in the  circumstances
     contemplated  by clause  (2) of this  sentence  will  relate  solely to the
     Private  Exchange  Securities)  pursuant to Section 3. The  parties  hereto
     agree that,  following  the  delivery  of a Shelf  Notice to the Holders of
     Registrable  Securities (only in the circumstances  contemplated by clauses
     (1) and/or (3) of the preceding  sentence),  the Company shall not have any
     further  obligation to conduct the Exchange  Offer or the Private  Exchange
     under this Section 2.

3. Shelf Registration
   ------------------

     If a Shelf Notice is delivered as contemplated by Section 2(c), then:

          (a)  Initial  Shelf  Registration.  The  Company  shall as promptly as
     reasonably  practicable  prepare  and  file  with  the  SEC a  Registration
     Statement for an offering to be made on a continuous basis pursuant to Rule
     415  covering  all  of  the  Registrable  Securities  (the  "Initial  Shelf
     Registration").  If the  Company  shall  have  not yet  filed  an  Exchange
     Registration  Statement,  the Company shall use its reasonable best efforts
     to file  with the SEC the  Initial  Shelf  Registration  on or prior to the
     Filing Date.  Otherwise,  the Company shall use its reasonable best efforts
     to file with the SEC the Initial Shelf  Registration  within 60 days of the
     delivery of the Shelf Notice.  The Initial Shelf  Registration  shall be on
     Form  S-3 or  another  appropriate  form  permitting  registration  of such
     Registrable  Securities for resale by such holders in the manner or manners
     designated by them (including, without limitation, one or more underwritten
     offerings).  The  Company  shall not permit any  securities  other than the
     Registrable  Securities to be included in the Initial Shelf Registration or
     any Subsequent Shelf Registration (as defined below). The Company shall use
     its reasonable  best efforts to cause the



<PAGE>
                                       9


     Initial Shelf  Registration  to be declared  effective under the Securities
     Act on or prior to the 180th day after the filing  thereof with the SEC and
     to keep the Initial Shelf  Registration  continuously  effective  under the
     Securities  Act until  the date  which is 24  months  from the  Issue  Date
     (subject to extension  pursuant to the last  paragraph of Section 5 hereof)
     (the  "Effectiveness  Period"),  or such shorter period ending when (i) all
     Registrable  Securities covered by the Initial Shelf Registration have been
     sold in the  manner  set forth and as  contemplated  in the  Initial  Shelf
     Registration or (ii) a Subsequent  Shelf  Registration  covering all of the
     Registrable  Securities  has been declared  effective  under the Securities
     Act.

          (b) Subsequent Shelf Registrations.  If the Initial Shelf Registration
     or any Subsequent Shelf Registration  ceases to be effective for any reason
     at any time during the Effectiveness Period (other than because of the sale
     of all of the securities registered thereunder),  the Company shall use its
     reasonable  best  efforts  to obtain  the  prompt  withdrawal  of any order
     suspending the effectiveness thereof, and in any event shall within 45 days
     of such cessation of effectiveness amend the Shelf Registration in a manner
     reasonably  expected to obtain the  withdrawal of the order  suspending the
     effectiveness thereof, or file an additional "shelf" Registration Statement
     pursuant  to  Rule  415  covering  all of  the  Registrable  Securities  (a
     "Subsequent  Shelf  Registration").  If a Subsequent Shelf  Registration is
     filed,  the  Company  shall use its  reasonable  best  efforts to cause the
     Subsequent  Shelf   Registration  to  be  declared  effective  as  soon  as
     practicable  after  such  filing  and to keep such  Registration  Statement
     continuously  effective  for a period  equal to the  number  of days in the
     Effectiveness  Period less the  aggregate  number of days during  which the
     Initial  Shelf  Registration  or  any  Subsequent  Shelf  Registration  was
     previously   continuously   effective.  As  used  herein  the  term  "Shelf
     Registration" means the Initial Shelf Registration and any Subsequent Shelf
     Registration.

          (c) Supplements and Amendments.  The Company shall promptly supplement
     and amend the Shelf  Registration if required by the rules,  regulations or
     instructions  applicable  to the  registration  form  used for  such  Shelf
     Registration, if required by the Securities Act, or if reasonably requested
     by  the  Holders  of a  majority  in  aggregate  principal  amount  of  the
     Registrable  Securities  covered by



<PAGE>
                                       10


     such  Registration  Statement  or by any  underwriter  of such  Registrable
     Securities.

4. Additional Interest
   -------------------

          (a) The Company and the Initial  Purchasers  agree that the Holders of
     Registrable  Securities will suffer damages if the Company fails to fulfill
     its  obligations  under Section 2 or Section 3 hereof and that it would not
     be  feasible  to  ascertain  the  extent of such  damages  with  precision.
     Accordingly,  the Company agrees to pay, as liquidated damages,  additional
     interest on the Registrable  Securities  ("Additional  Interest") under the
     circumstances  and to the extent set forth  below  (each of which  shall be
     given independent effect and shall not be duplicative):

          (i) if either the Exchange Registration Statement or the Initial Shelf
     Registration  (in the  event  the  Exchange  Offer is not  permitted  under
     applicable law or Commission  policy) has not been filed on or prior to the
     Filing Date, as the case may be,  Additional  Interest  shall accrue on the
     Registrable Securities over and above the stated interest at a rate of .50%
     per annum for the first 90 days immediately following the Filing Date, such
     Additional Interest rate increasing to 1.0% per annum thereafter;

          (ii) if either the  Exchange  Registration  Statement  is not declared
     effective by the Commission, or the Initial Shelf Registration is not filed
     with the Commission, on or prior to the Effectiveness Date, as the case may
     be,  Additional  Interest shall accrue on the Registrable  Securities which
     are or should have been included in such  Registration  Statement  over and
     above the stated interest at a rate of .50% per annum for the first 90 days
     immediately following the day after the Effectiveness Date, such Additional
     Interest rate increasing to 1.0% thereafter; and

          (iii) if (A) the Company has not exchanged Exchange Securities for all
     Securities  validly  tendered in accordance  with the terms of the Exchange
     Offer on or prior to the Consummation  Date, (B) the Exchange  Registration
     Statement  ceases to be  effective  at any time  prior to the time that the
     Exchange  Offer  is   consummated  or  (C)(1)  if  applicable,   the  Shelf
     Registration   has  not  been  declared   effective  on  or  prior  to  the
     Consummation Date or (2) such Shelf Registration  ceases to be effective at
     any time from and after the Consummation  Date and during the Effectiveness
     Period, then Additional Interest shall accrue on the



<PAGE>
                                       11


     Registrable  Securities (over and above any interest  otherwise  payable on
     the  Registrable  Securities)  at a rate of .50% per annum for the first 90
     days  commencing  on the (x) 181st day after the Issue Date, in the case of
     (A) and  (C)(1)  above,  (y) the day the  Exchange  Registration  Statement
     ceases to be effective in the case of (B) above,  or (z) the day such Shelf
     Registration  ceases  to be  effective  in the case of (C)(2)  above,  such
     Additional Interest rate increasing to 1.0% thereafter;

provided,  however,  that (1)  upon  the  filing  of the  Exchange  Registration
Statement or a Shelf  Registration as required  hereunder (in the case of clause
(i) of this Section 4), (2) upon the effectiveness of the Exchange  Registration
Statement or filing of the Shelf Registration as required hereunder (in the case
of  clause  (ii) of this  Section  4),  or (3) upon  the  exchange  of  Exchange
Securities for all Securities  tendered (in the case of clause  (iii)(A) of this
Section 4), or upon the  effectiveness  of the Exchange  Registration  Statement
which had ceased to remain  effective  (in the case of (iii)(B) of this  Section
4), or upon the effectiveness of the Shelf Registration (in the case of (iii)(c)
1 of  this  Section  4)  which  had or  upon  the  effectiveness  of  the  Shelf
Registration which had ceased to remain effective (in the case of (iii)(C)(2) of
this Section 4), Additional  Interest on the Registrable  Securities as a result
of such clause (or the relevant  subclause  thereof),  as the case may be, shall
cease to accrue.  It being  understood  and  agreed  that,  notwithstanding  any
provision to the contrary,  so long as any Registrable  Security is then covered
by an effective  Shelf  Registration  Statement,  no Additional  Interest  shall
accrue on such Registrable Security.

          (b) The Company shall notify the Trustee within one business day after
     each and every date on which an event occurs in respect of which Additional
     Interest is required to be paid (an "Event  Date").  The Company  shall pay
     the  Additional  Interest due on the  Registrable  Securities by depositing
     with the Trustee,  in trust, for the benefit of the Holders thereof,  on or
     before  the  applicable  semi-annual  interest  payment  date,  immediately
     available funds in sums sufficient to pay the Additional  Interest then due
     to Holders of Registrable Securities.  The Additional Interest due shall be
     payable on each interest  payment date to the record Holder of  Registrable
     Securities entitled to receive the interest payment to be made on such date
     as set forth in the  Indenture.  The amount of Additional  Interest will be
     determined by multiplying  the applicable  Additional  Interest rate by the
     principal



<PAGE>
                                       12


     amount of the affected Registrable  Securities of such Holders,  multiplied
     by a fraction, the numerator of which is the number of days such Additional
     Interest rate was applicable during such period (determined on the basis of
     a 360-day  year  comprised  of twelve  30-day  months and, in the case of a
     partial month,  the actual number of days elapsed),  and the denominator of
     which is 360. Each obligation to pay Additional Interest shall be deemed to
     accrue  immediately  following the occurrence of the applicable Event Date.
     The parties hereto agree that the Additional  Interest provided for in this
     Section 4  constitutes  a  reasonable  estimate of the damages  that may be
     incurred by Holders of Registrable Securities by reason of the failure of a
     Shelf Registration or Exchange Offer to be filed or declared effective,  or
     a Shelf Registration to remain effective, as the case may be, in accordance
     with this Section 4.

5. Registration Procedures
   -----------------------

     In connection with the registration of any Registrable  Securities pursuant
to Sections 2 or 3 hereof, the Company shall effect such registrations to permit
the sale of such  Registrable  Securities in accordance with the intended method
or methods of disposition thereof, and pursuant thereto the Company shall:

          (a) Use its reasonable  best efforts to prepare and file with the SEC,
     as soon as practicable  after the date hereof but in any event prior to the
     Filing Date in the case of the Exchange  Registration  Statement or, in the
     event  the  Exchange  Offer  is  not  permitted  under  applicable  law  or
     Commission policy, a Shelf Registration  Statement or the Consummation Date
     in the case of the Shelf  Registration  Statement  (filed for reasons other
     than  those  stated  above),  a  Registration   Statement  or  Registration
     Statements as prescribed by Section 2 or 3, and to use its reasonable  best
     efforts to cause each such  Registration  Statement to become effective and
     remain effective as provided  herein,  provided that, if (1) such filing is
     pursuant  to  Section  3,  or (2) a  Prospectus  contained  in an  Exchange
     Registration  Statement  filed  pursuant  to  Section 2 is  required  to be
     delivered under the Securities Act by any  Participating  Broker-Dealer who
     seeks to sell Exchange  Securities  during the  Applicable  Period,  before
     filing any  Registration  Statement  or  Prospectus  or any  amendments  or
     supplements  thereto, the Company shall upon written request furnish to and
     afford the Holders of the Registrable



<PAGE>
                                       13


     Securities  (which  in the case of  Registrable  Securities  in the form of
     global certificates shall be The Depository Trust Company ("DTC")) and each
     such  Participating  Broker-Dealer,  as the  case may be,  covered  by such
     Registration  Statement,  their counsel and the managing  underwriters,  if
     any,  a  reasonable  opportunity  to review  copies  of all such  documents
     (including  copies of any documents to be incorporated by reference therein
     and all exhibits thereto) proposed to be filed.

          (b) Prepare and file with the SEC such  amendments and  post-effective
     amendments to each Shelf Registration or Exchange  Registration  Statement,
     as the case may be, as may be necessary to keep such Registration Statement
     continuously  effective  for the  Effectiveness  Period  or the  Applicable
     Period, as the case may be; cause the related Prospectus to be supplemented
     by any required Prospectus  supplement,  and as so supplemented to be filed
     pursuant to Rule 424 (or any similar  provisions  then in force)  under the
     Securities  Act; and comply with the provisions of the Securities  Act, the
     Exchange  Act  and  the  rules  and  regulations  of  the  SEC  promulgated
     thereunder  applicable  to it  with  respect  to  the  disposition  of  all
     securities covered by such Registration  Statement as so amended or in such
     Prospectus as so supplemented and with respect to the subsequent  resale of
     any securities being sold by a Participating  Broker-Dealer  covered by any
     such  Prospectus;  the  Company  shall  not be  deemed  to  have  used  its
     reasonable best efforts to keep a Registration  Statement  effective during
     the  Applicable  Period if the  Company  voluntarily  takes any action that
     would  result in selling  Holders  of the  Registrable  Securities  covered
     thereby or Participating Broker-Dealers seeking to sell Exchange Securities
     not  being  able to  sell  such  Registrable  Securities  or such  Exchange
     Securities  during that period unless such action is required by applicable
     law or unless the Company complies with this Agreement,  including  without
     limitation,  the provisions of paragraph 5(k) hereof and the last paragraph
     of this Section 5.

          (c) If (1) a Shelf Registration is filed pursuant to Section 3, or (2)
     a Prospectus contained in an Exchange Registration Statement filed pursuant
     to Section 2 is required to be delivered  under the  Securities  Act by any
     Participating  Broker-Dealer  who seeks to sell Exchange  Securities during
     the  Applicable   Period,   notify  the  selling   Holders  of  Registrable
     Securities, or each such Participating  Broker-Dealer,  as the case may be,
     their coun-



<PAGE>
                                       14


     sel and the managing  underwriters,  if any, who have  provided the Company
     with  their  names and  addresses  promptly  (but in any event  within  two
     business days),  and confirm such notice in writing,  (i) when a Prospectus
     or any Prospectus  supplement or  post-effective  amendment has been filed,
     and,  with  respect  to a  Registration  Statement  or  any  post-effective
     amendment,  when the same has become  effective  under the  Securities  Act
     (including  in such notice a written  statement  that any Holder may,  upon
     request,  obtain,  without charge,  one conformed copy of such Registration
     Statement or post-effective  amendment including  financial  statements and
     schedules, documents incorporated or deemed to be incorporated by reference
     and exhibits), (ii) of the issuance by the SEC of any stop order suspending
     the effectiveness of a Registration Statement or of any order preventing or
     suspending the use of any  preliminary  prospectus or the initiation of any
     proceedings  for that  purpose,  (iii) of the receipt by the Company of any
     notification  with  respect  to  the  suspension  of the  qualification  or
     exemption  from  qualification  of a  Registration  Statement or any of the
     Registrable  Securities  or  the  Exchange  Securities  to be  sold  by any
     Participating  Broker-Dealer for offer or sale in any jurisdiction,  or the
     initiation or threatening  of any proceeding for such purpose,  (iv) of the
     happening  of any event or any  information  becoming  known that makes any
     statement made in such Registration  Statement or related Prospectus or any
     document  incorporated  or deemed to be  incorporated  therein by reference
     untrue in any material  respect or that  requires the making of any changes
     in such  Registration  Statement,  Prospectus  or documents so that, in the
     case  of the  Registration  Statement,  it  will  not  contain  any  untrue
     statement of a material fact or omit to state any material fact required to
     be  stated  therein  or  necessary  to  make  the  statements  therein  not
     misleading, and that in the case of the Prospectus, it will not contain any
     untrue  statement  of a material  fact or omit to state any  material  fact
     required to be stated therein or necessary to make the statements  therein,
     in the  light  of  the  circumstances  under  which  they  were  made,  not
     misleading,  and  (v)  of the  Company's  reasonable  determination  that a
     post-effective amendment to a Registration Statement would be appropriate.

          (d) If (1) a Shelf Registration is filed pursuant to Section 3, or (2)
     a Prospectus contained in an Exchange Registration Statement filed pursuant
     to Section 2 is required to be delivered  under the  Securities  Act by any



<PAGE>
                                       15


     Participating  Broker-Dealer  who seeks to sell Exchange  Securities during
     the  Applicable  Period,  use its  reasonable  best  efforts to prevent the
     issuance  of any  order  suspending  the  effectiveness  of a  Registration
     Statement or of any order  preventing or suspending the use of a Prospectus
     or suspending the qualification (or exemption from qualification) of any of
     the  Registrable  Securities  or the Exchange  Securities to be sold by any
     Participating Broker-Dealer, for sale in any jurisdiction, and, if any such
     order  is  issued,  to use  its  reasonable  best  efforts  to  obtain  the
     withdrawal of any such order at the earliest possible moment.

          (e) If a Shelf  Registration  is filed  pursuant  to  Section 3 and if
     requested  by the  managing  underwriters,  if  any,  or the  Holders  of a
     majority in aggregate principal amount of the Registrable  Securities being
     sold in connection with an underwritten  offering, (i) promptly incorporate
     in a prospectus supplement or post-effective  amendment such information as
     the managing  underwriters,  if any, or such Holders or counsel  reasonably
     request to be included  therein,  or (ii) make all required filings of such
     prospectus   supplement  or  such  post-effective   amendment  as  soon  as
     practicable  after the Company has received  notification of the matters to
     be incorporated in such prospectus supplement or post-effective amendment.

          (f) If (1) a Shelf Registration is filed pursuant to Section 3, or (2)
     a Prospectus contained in an Exchange Registration Statement filed pursuant
     to Section 2 is required to be delivered  under the  Securities  Act by any
     Participating  Broker-Dealer  who seeks to sell Exchange  Securities during
     the  Applicable  Period,  furnish  to each  selling  Holder of  Registrable
     Securities and to each such Participating Broker-Dealer who so requests and
     to counsel and each  managing  underwriter,  if any,  without  charge,  one
     conformed  copy  of the  Registration  Statement  or  Statements  and  each
     post-effective  amendment  thereto,   including  financial  statements  and
     schedules,  and if requested,  all documents  incorporated  or deemed to be
     incorporated therein by reference and all exhibits.

          (g) If (1) a Shelf Registration is filed pursuant to Section 3, or (2)
     a Prospectus contained in an Exchange Registration Statement filed pursuant
     to Section 2 is required to be delivered  under the  Securities  Act by any

     selling  Holder  of  Registrable  Securities,  or each  such  Participating
     Broker-Dealer,  as the case may be, their counsel, and the underwriters, if
     any,  without  charge,  as many copies of the  Prospectus  or  Prospectuses
     (including  each form of  preliminary  prospectus)  and each  amendment  or
     supplement  thereto and any documents  incorporated by reference therein as
     such Persons may reasonably request;  and, subject to the last paragraph of
     this Section 5, the Company hereby  consents to the use of such  Prospectus
     and each amendment or supplement  thereto by each of the selling holders of
     Registrable  Securities or each such  Participating  Broker-Dealer,  as the
     case may be, and the underwriters or agents,  if any, and dealers (if any),
     in  connection  with the  offering and sale of the  Registrable  Securities
     covered  by or the sale by  Participating  Broker-Dealers  of the  Exchange
     Securities  pursuant to such  Prospectus  and any  amendment or  supplement
     thereto.

          (h) Prior to any public  offering  of  Registrable  Securities  or any
     delivery of a Prospectus contained in the Exchange  Registration  Statement
     by any Participating  Broker-Dealer  who seeks to sell Exchange  Securities
     during  the  Applicable  Period,  to use its  reasonable  best  efforts  to
     register  or  qualify,  and  to  cooperate  with  the  selling  Holders  of
     Registrable  Securities or each such  Participating  Broker-Dealer,  as the
     case may be, the  underwriters,  if any,  and their  respective  counsel in
     connection with the registration or  qualification  (or exemption from such
     registration or qualification) of such Registrable Securities for offer and
     sale under the securities or Blue Sky laws of such jurisdictions within the
     United States as any selling Holder,  Participating  Broker-Dealer,  or the
     managing  underwriters  reasonably request in writing,  provided that where
     Exchange  Securities held by  Participating  Broker-Dealers  or Registrable
     Securities  are offered other than through an  underwritten  offering,  the
     Company agrees to cause its counsel to perform Blue Sky  investigations and
     file registrations and qualifications required to be filed pursuant to this
     Section 5(h); keep each such  registration or  qualification  (or exemption
     therefrom)  effective  during the period  such  Registration  Statement  is
     required to be kept effective and do any and all other  reasonable  acts or
     things   necessary  or  advisable  to  enable  the   disposition   in  such
     jurisdictions   of  the   Exchange   Securities   held   by   Participating
     Broker-Dealers  or the  Registrable  Securities  covered by the  applicable
     Registration Statement,  provided that the Company shall not be required to
     (A) qualify generally to do business in any jurisdic-


<PAGE>
                                       17


     tion  where it is not then so  qualified,  (B) take any  action  that would
     subject it to general service of process in any such jurisdiction  where it
     is not then so subject or (C)  subject  itself to  taxation  in excess of a
     nominal dollar amount in any such jurisdiction.

          (i) If a Shelf Registration is filed pursuant to Section 3, reasonably
     cooperate  with the  selling  Holders  of  Registrable  Securities  and the
     managing  underwriters,  if any, to facilitate the timely  preparation  and
     delivery of certificates  representing  Registrable  Securities to be sold,
     which certificates shall not bear any restrictive legends and shall be in a
     form eligible for deposit with DTC; and enable such Registrable  Securities
     to be registered in such names as the managing underwriter or underwriters,
     if any, or Holders may request.

          (j)  Use  its  reasonable   best  efforts  to  cause  the  Registrable
     Securities  covered by the Registration  Statement to be registered with or
     approved by such other United States  governmental  agencies or authorities
     of the United  States as may be  necessary  to enable the seller or sellers
     thereof or the underwriters,  if any, to consummate the disposition of such
     Registrable  Securities,  except as may be required solely as a consequence
     of the nature of such selling Holder's business,  in which case the Company
     will  cooperate  in  all  reasonable  respects  with  the  filing  of  such
     Registration Statement and the granting of such approvals.

          (k) If (1) a Shelf Registration is filed pursuant to Section 3, or (2)
     a Prospectus contained in an Exchange Registration Statement filed pursuant
     to Section 2 is required to be delivered  under the  Securities  Act by any
     Participating  Broker-Dealer  who seeks to sell Exchange  Securities during
     the Applicable  Period,  upon the occurrence of any event  contemplated  by
     paragraph 5(c)(iv) or 5(c)(v) above, as promptly as practicable prepare and
     (subject to Section 5(a) above) file with the SEC, solely at the expense of
     the Company,  a supplement or post-effective  amendment to the Registration
     Statement  or a  supplement  to the  related  Prospectus  or  any  document
     incorporated or deemed to be incorporated therein by reference, or file any
     other required document so that, as thereafter  delivered to the purchasers
     of the Registrable Securities being sold thereunder or to the purchasers of
     the  Exchange  Securities  to whom such  Prospectus  will be delivered by a
     Participating Broker-Dealer, any such Pro-


<PAGE>
                                       18


     spectus will not contain an untrue  statement of a material fact or omit to
     state a material  fact  required to be stated  therein or necessary to make
     the statements  therein, in the light of the circumstances under which they
     were made, not misleading.

          (l)  Use  its  reasonable   best  efforts  to  cause  the  Registrable
     Securities covered by a Registration  Statement or the Exchange Securities,
     as the case may be, to be rated with the appropriate rating agencies, if so
     requested  by the Holders of a majority in  aggregate  principal  amount of
     Registrable  Securities  covered  by  such  Registration  Statement  or the
     Exchange Securities,  as the case may be, or the managing underwriters,  if
     any.

          (m) Prior to the effective  date of the first  Registration  Statement
     relating to the  Registrable  Securities,  (i)  provide  the  Trustee  with
     printed certificates for the Registrable  Securities in a form eligible for
     deposit  with DTC and (ii)  provide  a CUSIP  numbers  for the  Registrable
     Securities.

          (n) Use its best efforts to cause all Registrable  Securities  covered
     by such Registration Statement or the Exchange Securities,  as the case may
     be, to be (i) listed on each securities exchange,  if any, on which similar
     securities  issued by the Company are then listed, or (ii) authorized to be
     quoted  on  the  National   Association  of  Securities  Dealers  Automated
     Quotation  System  ("NASDAQ")  or the National  Market  System of NASDAQ if
     similar securities of the Company are so authorized.

          (o)  In  connection  with  an  underwritten  offering  of  Registrable
     Securities  pursuant to a Shelf  Registration,  enter into an  underwriting
     agreement as is customary in underwritten offerings and take all such other
     actions as are reasonably  requested by the managing  underwriters in order
     to expedite or  facilitate  the  registration  or the  disposition  of such
     Registrable   Securities,   and  in  such   connection,   (i)   make   such
     representations  and  warranties to the  underwriters,  with respect to the
     business of the Company and its subsidiaries,  if any, and the Registration
     Statement,  Prospectus and documents,  if any, incorporated or deemed to be
     incorporated by reference therein, in each case, as are customarily made by
     issuers to underwriters in underwritten offerings,  and confirm the same if
     and when  requested;  (ii)  obtain an opinion of counsel to the Company and
     updates thereof in form and


<PAGE>
                                       19


     substance reasonably  satisfactory to the managing underwriters,  addressed
     to the underwriters  covering the matters  customarily  covered in opinions
     requested  in  underwritten  offerings  and such  other  matters  as may be
     reasonably  requested by underwriters;  (iii) obtain "cold comfort" letters
     and updates  thereof in form and substance  reasonably  satisfactory to the
     managing  underwriters from the independent  certified public accountant(s)
     of the Company (and, if necessary,  any other independent  certified public
     accountants of any subsidiary of the Company or of any business acquired by
     the Company for which  financial  statements and financial data are, or are
     required to be, included in the Registration Statement),  addressed to each
     of the  underwriters,  such  letters to be in  customary  form and covering
     matters  of the type  customarily  covered  in "cold  comfort"  letters  in
     connection  with  underwritten  offerings  and such other matters as may be
     reasonably requested by underwriters; and (iv) if an underwriting agreement
     is entered into,  the same shall  contain  indemnification  provisions  and
     procedures no less  favorable  than those set forth in Section 7 hereof (or
     such other provisions and procedures acceptable to Holders of a majority in
     aggregate  principal  amount  of  Registrable  Securities  covered  by such
     Registration  Statement  and the  managing  underwriters  or  agents)  with
     respect to all  parties to be  indemnified  pursuant to said  Section.  The
     above shall be done at each closing under such underwriting  agreement,  or
     as and to the extent required thereunder.

          (p) If (1) a Shelf Registration is filed pursuant to Section 3, or (2)
     a Prospectus contained in an Exchange Registration Statement filed pursuant
     to Section 2 is required to be delivered  under the  Securities  Act by any
     Participating  Broker-Dealer  who seeks to sell Exchange  Securities during
     the Applicable Period,  make available for inspection by any selling Holder
     of such  Registrable  Securities  being  sold,  or each such  Participating
     Broker-Dealer,  as the case may be, any  underwriter  participating  in any
     such  disposition  of  Registrable  Securities,  if any, and any  attorney,
     accountant or other agent  retained by any such selling holder or each such
     Participating   Broker-Dealer,   as  the  case  may  be,   or   underwriter
     (collectively,  the  "Inspectors"),  at the offices  where  normally  kept,
     during  reasonable   business  hours,  all  financial  and  other  records,
     pertinent  corporate  documents  and  properties  of the  Company  and  its
     subsidiaries (collectively, the "Records"), as shall be reasonably nec-


<PAGE>
                                       20


     essary  to  enable  them  to  exercise   any   applicable   due   diligence
     responsibilities,  and cause the  officers,  directors and employees of the
     Company to supply all information in each case reasonably  requested by any
     such  Inspector in connection  with such  Registration  Statement.  Records
     determined  in good faith by the  Company to be  confidential  shall not be
     disclosed by any Inspector  notified of such  determination  unless (i) the
     disclosure of such Records is necessary to avoid or correct a  misstatement
     or  omission  in such  Registration  Statement,  (ii) the  release  of such
     Records is ordered  pursuant  to a subpoena  or other order from a court of
     competent  jurisdiction  or (iii) the  information in such Records has been
     made  generally  available  to the  public.  Each  selling  Holder  of such
     Registrable  Securities and each such  Participating  Broker-Dealer will be
     required  to agree  that  information  obtained  by it as a result  of such
     inspections shall be deemed confidential and shall not be used by it as the
     basis for any market  transactions  in the securities of the Company unless
     and until such is made  generally  available  to the public.  Each  selling
     Holder  of  such  Registrable   Securities  and  each  such   Participating
     Broker-Dealer will be required to further agree that it will, upon learning
     that  disclosure  of  such  Records  is  sought  in a  court  of  competent
     jurisdiction,  give  notice to the  Company  and allow the  Company  at its
     expense  to  undertake  appropriate  action to  prevent  disclosure  of the
     Records deemed confidential.

          (q) Provide an indenture trustee for the Registrable Securities or the
     Exchange  Securities,  as the case may be, and cause the  Indenture  or the
     trust  indenture  provided for in Section  2(a),  as the case may be, to be
     qualified  under the TIA not later than the effective  date of the Exchange
     Offer or the  first  Registration  Statement  relating  to the  Registrable
     Securities;  and in connection therewith,  cooperate with the trustee under
     any such indenture and the holders of the Registrable Securities, to effect
     such changes to such  indenture as may be required for such indenture to be
     so qualified in accordance with the terms of the TIA; and execute,  and use
     its reasonable best efforts to cause such trustee to execute, all documents
     as may be  required  to  effect  such  changes,  and all  other  forms  and
     documents  required to be filed with the SEC to enable such indenture to be
     so qualified in a timely manner.

          (r) Comply in all  material  respects  with all  applicable  rules and
     regulations of the SEC and make generally


<PAGE>
                                       21


     available  to  its  securityholders   earning  statements   satisfying  the
     provisions of Section 11(a) of the  Securities  Act and Rule 158 thereunder
     (or any similar rule promulgated under the Securities Act) no later than 90
     days after the end of any 12-month  period (i) commencing at the end of any
     fiscal quarter in which Registrable  Securities are sold to underwriters in
     a firm  commitment  or best efforts  underwritten  offering and (ii) if not
     sold to  underwriters  in such an offering,  commencing on the first day of
     the first fiscal quarter of the Company after the effective date of a Shelf
     Registration Statement, which statements shall cover said 12-month periods.

          (s) If an Exchange Offer or a Private  Exchange is to be  consummated,
     upon delivery of the  Registrable  Securities by Holders to the Company (or
     to such other  Person as  directed  by the  Company)  in  exchange  for the
     Exchange Securities or the Private Exchange Securities, as the case may be,
     the  Company  shall  mark,  or caused  to be  marked,  on such  Registrable
     Securities that such Registrable Securities are being cancelled in exchange
     for the Exchange Securities or the Private Exchange Securities, as the case
     may be; in no event shall such Registrable  Securities be marked as paid or
     otherwise satisfied.

          (t) Reasonably  cooperate  with each seller of Registrable  Securities
     covered  by any  Registration  Statement  and  each  underwriter,  if  any,
     participating in the disposition of such  Registrable  Securities and their
     respective  counsel in connection with any filings required to be made with
     the National Association of Securities Dealers, Inc. (the "NASD").

          (u) Use its reasonable  best efforts to take all other steps necessary
     to effect  the  registration  of the  Registrable  Securities  covered by a
     Registration Statement contemplated hereby.

     The  Company  may  require  each  seller  of   Registrable   Securities  or
Participating  Broker-Dealer  as to which any  registration is being effected to
furnish to the Company such  information  regarding such seller or Participating
Broker-Dealer  and the distribution of such  Registrable  Securities or Exchange
Securities to be sold by such Participating  Broker-Dealer,  as the case may be,
as the  Company  may,  from time to time,  reasonably  request.  The Company may
exclude  from such  registration  the  Registrable  Securities  of any seller or
Participating  Broker-Dealer who unreasonably  fails to furnish such informa-


<PAGE>
                                       22


tion within a reasonable  time after  receiving such request.  Each seller as to
which any Shelf  Registration  is being  effected  is deemed to agree to furnish
promptly to the Company all  information  required to be  disclosed  in order to
make the  information  previously  furnished  to the  Company by such seller not
materially misleading.

     Each Holder of Registrable Securities and each Participating  Broker-Dealer
agrees by acquisition of such Registrable  Securities or Exchange  Securities to
be sold by such  Participating  Broker-Dealer,  as the case may be,  that,  upon
receipt of any notice from the Company of the happening of any event of the kind
described in Section 5(c)(ii),  5(c)(iii), 5(c)(iv) or 5(c)(v), such Holder will
forthwith discontinue disposition of such Registrable Securities covered by such
Registration  Statement or Prospectus or Exchange  Securities to be sold by such
Participating Broker-Dealer,  as the case may be, until such holder's receipt of
the copies of the  supplemented  or amended  Prospectus  contemplated by Section
5(k),  or until it is advised in writing (the  "Advice") by the Company that the
use of the applicable  Prospectus may be resumed, and has received copies of any
amendments or supplements  thereto. In the event the Company shall give any such
notice,  each of the  Effectiveness  Period and the  Applicable  Period shall be
extended by the number of days during such periods from and  including  the date
of the  giving of such  notice  to and  including  the date when each  seller of
Registrable  Securities  covered  by such  Registration  Statement  or  Exchange
Securities to be sold by such Participating  Broker-Dealer,  as the case may be,
shall have  received (x) the copies of the  supplemented  or amended  Prospectus
contemplated by Section 5(k) or (y) the Advice.

6. Registration Expenses
   ---------------------

          (a) All fees and expenses incident to the performance of or compliance

     ment under the laws of such  jurisdictions  in the United  States (x) where
     the  holders of  Registrable  Securities  are  located,  in the case of the
     Exchange Securities,  or (y) as provided in Section 5(h) above, in the case
     of  Registrable   Securities  or  Exchange  Securities  to  be  sold  by  a
     Participating  Broker-Dealer during the Applicable Period)),  (ii) printing

<PAGE>
                                       24


     the Holders of a majority in aggregate  principal amount of the Registrable
     Securities  to be included in such  Registration  Statement.  Such  Holders
     shall be responsible  for any and all other  out-of-pocket  expenses of the
     Holders  of  Registrable   Securities   incurred  in  connection  with  the
     registration of the Registrable Securities.

7. Indemnification
   ---------------

     The  Company   agrees  to  indemnify  and  hold  harmless  each  Holder  of
Registrable  Securities and each  Participating  Broker-Dealer  selling Exchange
Securities during the Applicable Period, the officers and directors of each such
person, and each person, if any, who controls any such person within the meaning
of Section 15 of the  Securities  Act or Section 20 of the Exchange Act (each, a
"Participant"),   from  and  against  any  and  all  losses,  claims,   damages,
liabilities  and  judgments  caused by any untrue  statement  or alleged  untrue
statement  of a  material  fact  contained  in  any  Registration  Statement  or
Prospectus (as amended or  supplemented  if the Company shall have furnished any
amendments or supplements thereto) or any preliminary  prospectus,  or caused by
any omission or alleged omission to state therein a material fact required to be
stated  therein or  necessary  to make the  statements  therein not  misleading,
except  insofar as such losses,  claims,  damages,  liabilities or judgments are
caused by any such untrue  statement or omission or alleged untrue  statement or
omission based upon information relating to any Participant furnished in writing
to the Company by or on behalf of such  Participant  expressly  for use therein;
provided,  however,  that the foregoing  indemnity agreement with respect to any
preliminary  prospectus shall not inure to the benefit of any Participant (or to
the benefit of any person  controlling  such  Participant)  from whom the person
asserting any such losses, claims,  damages,  liabilities or judgments purchased
Registrable  Securities or Exchange  Securities if a copy of the  Prospectus (as
then amended or  supplemented if the Company shall have furnished any amendments
or  supplements  thereto)  was  not  sent  or  given  by or on  behalf  of  such
Participant to such person, if required by law so to have been delivered,  at or
prior to the written confirmation of the sale of such Registrable  Securities or
Exchange  Securities,  as the case may be, to such person, and if the Prospectus
(as so amended or supplemented)  would have cured the defect giving rise to such
losses, claims, damages, liabilities or judgments.

     Each Participant will be required to agree,  severally and not jointly,  to
indemnify and hold harmless the Company,  its  directors,  its officers and each
person, if any, who con-


<PAGE>
                                       25


trols the  Company  within the  meaning of Section 15 of the  Securities  Act or
Section 20 of the  Exchange  Act to the same extent as the  foregoing  indemnity
from the Company to each  Participant,  but only with  reference to  information
relating to such Participant furnished in writing to the Company by or on behalf
of  such  Participant  expressly  for  use  in  any  Registration  Statement  or
Prospectus,  any amendment or supplement thereto, or any preliminary prospectus.
The liability of any  Participant  under this paragraph shall in no event exceed
the proceeds  received by such Participant from sales of Registrable  Securities
giving rise to such obligations.

     In case any action shall be brought  against any person in respect of which
indemnity may be sought pursuant to either of the two preceding paragraphs, such
person (the "Indemnified  Person") shall promptly notify the person against whom
such  indemnity  may be sought  (the  "Indemnifying  Person") in writing and the
Indemnifying  Person shall assume the defense thereof,  including the employment
of counsel reasonably  satisfactory to the Indemnified Person and payment of all
fees and  expenses.  Any  Indemnified  Person  shall  have the  right to  employ
separate counsel in any such action and participate in the defense thereof,  but
the  fees  and  expenses  of  such  counsel  shall  be at the  expense  of  such
Indemnified   Person  unless  (i)  the  employment  of  such  counsel  has  been
specifically  authorized  in  writing  by  the  Indemnifying  Person,  (ii)  the
Indemnifying Person has failed to assume the defense and employ counsel or (iii)
the named parties to any such action  (including any impleaded  parties) include
both the  Indemnifying  Person and the Indemnified  Person and such  Indemnified
Party  shall  have been  advised by such  counsel  that there may be one or more
legal  defenses  available to it which are different from or additional to those
available  to the  Indemnifying  Person (in which case the  Indemnifying  Person
shall not have the right to assume the  defense of such action on behalf of such
Indemnified Person, it being understood,  however,  that the Indemnifying Person
shall not, in connection with any one such action or separate but  substantially
similar or  related  actions in the same  jurisdiction  arising  out of the same
general  allegations or  circumstances,  be liable for the  reasonable  fees and
expenses of more than one separate  firm of attorneys  (in addition to any local
counsel) for all Indemnified  Persons, and that all such fees and expenses shall
be reimbursed as they are incurred). Any such separate firm for the Participants
and such  control  persons of  Participants  shall be  designated  in writing by
Participants  who sold a majority in interest of Registrable  Securities sold by
all such Participants and any such separate

firm for the Company,  its directors,  officers and such control  persons of the
Company shall be designated in writing by the Company.  The Indemnifying  Person
shall not be liable for any settlement of any such action  effected  without its
written  consent,  but if settled  with the written  consent,  the  Indemnifying
Person  agrees to indemnify and hold  harmless any  Indemnified  Person from and
against any loss or liability by reason of such settlement.  Notwithstanding the
foregoing sentence, if at any time an Indemnified Person shall have requested an
Indemnifying Person to reimburse the Indemnified Person for fees and expenses of
counsel  as  contemplated   by  the  third  sentence  of  this  paragraph,   the
Indemnifying  Person  agrees that it shall be liable for any  settlement  of any
proceeding  effected  without  its  written  consent if (i) such  settlement  is
entered  into more than 10  business  days after  receipt  by such  Indemnifying
Person of the aforesaid request and (ii) such Indemnifying Person shall not have
reimbursed the  Indemnified  Person in accordance with such request prior to the
date of such settlement. No Indemnifying Person shall, without the prior written
consent of the  Indemnified  Person,  effect any  settlement  of any  pending or
threatened  proceeding  in respect of which any  Indemnified  Person is or could
have  been a party  and  indemnity  could  have been  sought  hereunder  by such
Indemnified Person,  unless such settlement includes an unconditional release of
such Indemnified Person from all liability on claims that are the subject matter
of such proceeding.

     If the  Indemnification  provided for in the first and second paragraphs of
this Section 7 is unavailable to an Indemnified Person in respect of any losses,
claims,  damages,  liabilities  or  judgments  referred  to  therein,  then each
Indemnifying  Person  under  such  paragraph,   in  lieu  of  indemnifying  such
Indemnified Person thereunder, shall contribute to the amount paid or payable by
such Indemnified Person as a result of such losses, claims, damages, liabilities
or judgments in such  proportion as is appropriate to reflect the relative fault
of the  Company  on the one  hand  and the  Participants  on the  other  hand in
connection  with the  statements  or  omissions  that  resulted in such  losses,
claims,  damages,  liabilities,  or  judgments  as  well as any  other  relevant
equitable considerations.  The relative fault of the Company on the one hand and
the  Participants  on the other hand shall be  determined by reference to, among
other things,  whether the untrue or alleged untrue statement of a material fact
or the  omission  or  alleged  omission  to state a  material  fact  relates  to
information  supplied by the  Company or by the  Participants  and the  parties'
relative intent, knowledge,  access to information and opportunity to correct or
prevent such statement or omission.



<PAGE>
                                       27


     The  parties  shall  agree  that it  would  not be just  and  equitable  if
contribution  pursuant  to the  prior  paragraph  were  determined  by pro  rata
allocation  (even  if the  Participants  were  treated  as one  entity  for such
purpose) or by any other method of allocation  that does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount  paid or  payable  by an  Indemnified  Person as a result of the  losses,
claims,  damages,  liabilities  or  judgments  referred  to in  the  immediately
preceding  paragraph shall be deemed to include,  subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such Indemnified
Person in connection with  investigating  or defending any such action or claim.
Notwithstanding  the  provisions  of this  Section  7, no  Participant  shall be
required  to  contribute  any amount in excess of the  amount by which  proceeds
received by such  Participant from sales of Registrable  Securities  exceeds the
amount of any damages that such  Participant  has otherwise been required to pay
by reason of such  untrue or alleged  untrue  statement  or  omission or alleged
omission. No person guilty of fraudulent  misrepresentation  (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to  contribution  from
any person who was not guilty of such fraudulent misrepresentation.

     The indemnity and contribution  agreements contained in this Section 7 will
be in addition to any  liability  which the  Indemnifying  Persons may otherwise
have to the Indemnified Persons referred to above.

8. Rule 144 and Rule 144A
   ----------------------

     The Company covenants that it will file the reports required to be filed by
it under the Securities  Act and the Exchange Act and the rules and  regulations
adopted by the SEC thereunder in a timely manner and, if at any time the Company
is not required to file such reports, it will, upon the request of any Holder of
Registrable  Securities,  make publicly  available other  information so long as
necessary  to  permit  sales  pursuant  to Rule  144 and  Rule  144A  under  the
Securities  Act. The Company  further  covenants  that it will take such further
action as any Holder of Registrable  Securities may reasonably  request,  all to
the extent required from time to time to enable such holder to sell  Registrable
Securities  without  registration under the Securities Act within the limitation
of the  exemptions  provided by (a) Rule 144 and Rule 144A under the  Securities
Act, as such rules may be amended from time to time,  or (b) any similar rule or
regulation hereafter adopted by the SEC.

9. Underwritten Registrations
   --------------------------

     If any of the Registrable  Securities covered by any Shelf Registration are
to be sold in an  underwritten  offering,  the  investment  banker or investment
bankers and manager or managers  that will manage the offering  will be selected
by the Holders of a majority in aggregate  principal  amount of such Registrable
Securities  included  in  such  offering  and be  reasonably  acceptable  to the
Company.

     No Holder of  Registrable  Securities may  participate in any  underwritten
registration  hereunder  unless  such  Holder (a)  agrees to sell such  Holder's
Registrable  Securities on the basis provided in any  underwriting  arrangements
approved by the Persons entitled  hereunder to approve such arrangements and (b)
completes  and executes  all  questionnaires,  powers of attorney,  indemnities,
underwriting  agreements  and other  documents  required under the terms of such
underwriting arrangements.

10. Miscellaneous
    -------------

          (a)  Remedies.  In the event of a breach by the  Company of any of its
     obligations under this Agreement, each Holder of Registrable Securities, in
     addition to being entitled to exercise all rights provided  herein,  in the
     Indenture  or,  in the  case of the  Initial  Purchasers,  in the  Purchase
     Agreement  or  granted  by law,  including  recovery  of  damages,  will be
     entitled to specific  performance of its rights under this  Agreement.  The
     Company agrees that monetary damages would not be adequate compensation for
     any loss  incurred by reason of a breach by it of any of the  provisions of
     this  Agreement  and hereby  further agree that, in the event of any action
     for specific performance in respect of such breach, the Company shall waive
     the defense that a remedy at law would be adequate.

          (b) No  Inconsistent  Agreements.  The Company has not, as of the date
     hereof, entered and shall not, after the date of this Agreement, enter into
     any agreement  with respect to any of its securities  that is  inconsistent
     with the rights  granted to the Holders of  Registrable  Securities in this
     Agreement or otherwise  conflicts with the provisions  hereof.  The Company
     has not entered and will not enter into any  agreement  with respect to any
     of its  securities  which will grant to any Person  piggy-back  rights with
     respect to a Registration Statement.



<PAGE>
                                       29



          (c) Adjustments  Affecting Registrable  Securities.  The Company shall
     not,  directly  or  indirectly,   take  any  action  with  respect  to  the
     Registrable  Securities as a class that would adversely  affect the ability
     of the  Holders  of  Registrable  Securities  to include  such  Registrable
     Securities in a registration undertaken pursuant to this Agreement.

          (d)  Amendments  and  Waivers.   The  provisions  of  this  Agreement,
     including the provisions of this sentence, may not be amended,  modified or
     supplemented,  and waivers or consents to  departures  from the  provisions
     hereof may not be given,  unless  the  Company  has  obtained  the  written
     consent of Holders of at least a majority of the then outstanding aggregate
     principal amount of Registrable Securities.  Notwithstanding the foregoing,
     a waiver or consent to depart from the provisions  hereof with respect to a
     matter that  relates  exclusively  to the rights of Holders of  Registrable
     Securities  whose  securities  are being sold  pursuant  to a  Registration
     Statement or to Holders of Notes or Debentures separately and that does not
     directly or indirectly  affect,  impair,  limit or compromise the rights of
     other  Holders of  Registrable  Securities  or the Holder of  Debentures or
     Notes,  respectively,  may be given by Holders  of at least a  majority  in
     aggregate principal amount of the Registrable Securities being sold by such
     Holders pursuant to such Registration Statement or by Holders of at least a
     majority  in  aggregate  principal  amount  of the Notes or  Debentures  so
     affected,  respectively,  provided that the provisions of this sentence may
     not be amended,  modified or  supplemented  except in  accordance  with the
     provisions of the immediately preceding sentence.

          (e) Notices. All notices and other  communications  (including without
     limitation any notices or other communications to the Trustee) provided for
     or  permitted   hereunder  shall  be  made  in  writing  by  hand-delivery,
     registered first-class mail, next-day air courier or telecopier:

          (i) if to a Holder  of  Registrable  Securities,  at the most  current
     address given by the Trustee to the Company; and

given: when delivered by hand, if personally delivered; five business days after
being deposited in the mail, postage prepaid,  if mailed; one business day after
being  timely  delivered  to  a  next-day  air  courier;  and  when  receipt  is
acknowledged by the addressee, if telecopied.

     Copies  of all  such  notices,  demands  or other  communications  shall be
concurrently  delivered  by the  Person  giving  the same to the  Trustee at the
address specified in the Indenture.

          (f) Successors and Assigns.  This Agreement shall inure to the benefit
     of and be binding upon the  successors  and assigns of each of the parties,
     including   without   limitation  and  without  the  need  for  an  express
     assignment,  subsequent Holders of Registrable Securities;  provided, that,
     with respect to the  indemnity  and  contribution  agreements in Section 7,
     each Holder of Registrable  Securities subsequent to the Initial Purchasers
     shall be bound by the  terms  thereof  if such  Holder  elects  to  include
     Registrable  Securities in a Shelf Registration;  provided,  however,  that
     this  Agreement  shall not inure to the  benefit  of or be  binding  upon a
     successor or assign of a Holder unless and to the extent such  successor or
     assign holds Registrable Securities.

          (g)  Counterparts.  This  Agreement  may be  executed in any number of
     counterparts  and by the parties hereto in separate  counterparts,  each of
     which when so executed  shall be deemed to be an original  and all of which
     taken together shall constitute one and the same agreement.

          (h) Headings.  The headings in this  Agreement are for  convenience of
     reference only and shall not limit or otherwise affect the meaning hereof.

          (i) Governing Law. THIS  AGREEMENT  SHALL BE GOVERNED BY AND CONSTRUED
     IN  ACCORDANCE  WITH  THE LAWS OF THE  STATE OF NEW  YORK,  AS  APPLIED  TO
     CONTRACTS MADE AND PERFORMED  WITHIN THE STATE OF NEW YORK,  WITHOUT REGARD
     TO  PRINCIPLES  OF CONFLICTS OF LAW.  EACH OF THE PARTIES  HERETO AGREES TO
     SUBMIT TO THE  JURISDICTION  OF THE  COURTS OF THE STATE OF NEW YORK IN ANY
     ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT.


<PAGE>
                                       31


          (j) Severability.  If any term, provision,  covenant or restriction of
     this Agreement is held by a court of competent  jurisdiction to be invalid,
     illegal,  void or  unenforceable,  the remainder of the terms,  provisions,
     covenants and  restrictions set forth herein shall remain in full force and
     effect and shall in no way be affected,  impaired or  invalidated,  and the
     parties  hereto  shall  use  their  best  efforts  to find  and  employ  an
     alternative  means to achieve the same or substantially  the same result as
     that contemplated by such term, provision,  covenant or restriction.  It is
     hereby stipulated and declared to be the intention of the parties that they
     would  have  executed  the  remaining  terms,  provisions,   covenants  and
     restrictions  without including any of such that may be hereafter  declared
     invalid, illegal, void or unenforceable.

          (k) Entire  Agreement.  This  Agreement,  together  with the  Purchase
     Agreement,  is  intended  by the  parties  as a final  expression  of their
     agreement,  and is intended to be a complete and exclusive statement of the
     agreement and understanding of the parties hereto in respect of the subject
     matter contained herein and therein.

          (l)  Securities  Held by the Company or Its  Affiliates.  Whenever the
     consent or  approval of holders of a specified  percentage  of  Registrable
     Securities  is  required  hereunder,  Registrable  Securities  held  by the
     Company or any of its affiliates (as such term is defined in Rule 405 under
     the  Securities  Act)  shall not be  counted in  determining  whether  such
     consent or approval was given by the Holders of such required percentage.

          (m)  Treatment  of Notes and  Debentures.  The Company  undertakes  to
     perform its  obligations  hereunder with respect to Registrable  Securities
     which are Notes and those  which  are  Debentures  in a  consistent  manner
     including, but not limited to, registering all Exchange Securities (whether
     to be exchange  for Notes or  Debentures  in the  Exchange  Offer),  to the
     extent  permitted by the rules and  regulations of the  Commission,  in the
     Exchange Registration Statement. In the event of disparite treatment of the
     Holders  of Notes and the  Debentures  hereunder,  whether by action of the
     Company,  the Commission or otherwise,  this Agreement  shall apply mutatis
     mutandis  to the Notes and the  Debentures  separately  and  Holders of the
     Notes and the Debentures will separately have all rights granted to Holders
     hereunder, including, but not limited to, the right to vote separately.

The AES Corporation
1001 North 19th Street
Arlington, Virginia 22209


Ladies and Gentlemen:

     We have acted as special counsel to The AES Corporation  (the "Company") in
connection with the Company's offer (the "Exchange Offer") to exchange its 8.50%
Senior Subordinated  Exchange Notes due 2007 (the "New 8.50% Notes") for any and
all of its outstanding 8.50% Senior  Subordinated Notes due 2007 (the "Old 8.50%
Notes") and to exchange its 8.875% Senior  Subordinated  Exchange Debentures due
2027 (the "New 8.875%  Debentures",  and, together with the New 8.50% Notes, the
"New  Notes")  for any and all of its  outstanding  8.875%  Senior  Subordinated
Debentures  due 2027 (the "Old 8.875%  Debentures"  and,  together  with the Old
8.50% Notes, the "Old Notes").

     We have examined originals or copies,  certified or otherwise identified to
our satisfaction,  of such documents,  corporate records, certificates of public
officials and other instruments as we have deemed necessary or advisable for the
purpose of rendering this opinion.

     Upon the basis of the foregoing and assuming the due execution and delivery
of the  Notes,  we are of  the  opinion  that  the  New  Notes,  when  executed,
authenticated and delivered in exchange for the Old Notes in accordance with the
Exchange Offer will be valid and binding  obligations of the Company enforceable
in  accordance  with the terms,  subject to applicable  bankruptcy,  insolvency,
reorganization,   moratorium  and  similar  laws  affecting   creditors'  rights
generally and equitable principles.

     We are  members  of the Bar of the  State  of New  York  and the  foregoing
opinion is limited to the laws of the State of New York, the federal laws of the
United  States  of  America  and the  General  Corporation  Law of the  State of
Delaware.

     We hereby  consent  to the  filing of this  opinion  as an  exhibit  to the
Registration  Statement  relating to the Exchange  Offer. We also consent to the
reference to us under the caption "Legal Matters" in the Prospectus contained in
such Registration Statement.

     This opinion is rendered solely to you in connection with the above matter.
This opinion may not be relied upon by you for any other  purpose or relied upon
by or furnished to any other person  without our prior  written  consent  except
that The First  National  Bank of Chicago,  as Exchange  Agent for the  Exchange
Offer may rely upon this opinion as if it were addressed directly to it.



                                          Very truly yours,

               PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

     Upon the terms and subject to the  conditions  of the Exchange  Offer,  the
undersigned hereby tenders to the Company the  above-described  principal amount
of Old Notes. Subject to, and effective upon, the acceptance for exchange of the
Old Notes tendered  herewith,  the  undersigned  hereby  exchanges,  assigns and
transfers to, or upon the order of, the Company all right, title and interest in
and to such Old  Notes.  The  undersigned  hereby  irrevocably  constitutes  and
appoints the Exchange Agent as the true and lawful agent and attorney-in-fact of
the undersigned  (with full knowledge that said Exchange Agent acts as the agent
of the undersigned in connection with the Exchange Offer) to cause the Old Notes
to be assigned,  transferred  and  exchanged.  The  undersigned  represents  and
warrants  that it has full power and authority to tender,  exchange,  assign and
transfer  the Old Notes and to acquire New Notes  issuable  upon the exchange of
such tendered Old Notes, and that, when the same are accepted for exchange,  the
Company will acquire good and unencumbered title to the tendered Old Notes, free
and clear of all liens,  restrictions,  charges and encumbrances and not subject
to any adverse claim.  The undersigned also warrants that it will, upon request,
execute and deliver any additional documents deemed by the Exchange Agent or the
Company to be necessary or desirable to complete the  exchange,  assignment  and
transfer of tendered  Old Notes or transfer  ownership  of such Old Notes on the
account books maintained by The Depository Trust Company.

     The  Exchange  Offer is subject to certain  conditions  as set forth in the
Prospectus  under the caption "The Exchange  Offer." The undersigned  recognizes
that as a result of these conditions  (which may be waived, in whole or in part,
by the Company),  as more particularly set forth in the Prospectus,  the Company
may not be  required to exchange  any of the Old Notes  tendered  hereby and, in
such event,  the Old Notes not exchanged will be returned to the  undersigned at
the address shown below the signature of the undersigned.

     By tendering,  each Holder of Old Notes  represents to the Company that (i)
the New Notes acquired  pursuant to the Exchange Offer are being obtained in the
ordinary course of business of the person  receiving such New Notes,  whether or
not such  person is such  Holder,  (ii)  neither the Holder of Old Notes nor any
such  other  person  has an  arrangement  or  understanding  with any  person to
participate in the distribution of such New Notes,  (iii) if the Holder is not a
broker-dealer  or is a broker-dealer  but will not receive New Notes for its own
account in exchange for Old Notes,  neither the Holder nor any such other person
is engaged in or intends to participate  in a distribution  of the New Notes and
(iv)  neither  the  Holder nor any such other  person is an  "affiliate"  of the
Company  within the  meaning of Rule 405 under the  Securities  Act of 1933,  as
amended  (the  "Act").  If the  tendering  Holder is a  broker-dealer  that will
receive New Notes for its own account in exchange for Old Notes,  it  represents
that the Old Notes to be  exchanged  for the New Notes were  acquired by it as a
result of market-making activities or other trading activities, and acknowledges
that it  will  deliver  a  prospectus  meeting  the  requirements  of the Act in
connection  with any resale of such New  Notes.  By  acknowledging  that it will
deliver and by delivering a prospectus  meeting the  requirements  of the Act in
connection  with any resale of such New Notes,  the undersigned is not deemed to
admit that it is an "underwriter" within the meaning of the Act.

     All authority  herein conferred or agreed to be conferred shall survive the
death,  bankruptcy or incapacity of the undersigned and every  obligation of the
undersigned hereunder shall be binding upon the heirs, personal representatives,
successors and assigns of the  undersigned.  Tendered Old Notes may be withdrawn
at any time prior to the Expiration Date.

     Certificates for all New Notes delivered in exchange for tendered Old Notes
and any Old Notes delivered herewith but not exchanged,  in each case registered
in the name of the  undersigned,  shall be delivered to the  undersigned  at the
address shown below the signature of the undersigned.

tendered  in the box  entitled  "Principal  Amount  Tendered."  A  newly  issued
certificate  for the  principal  amount of Old Notes  submitted but not tendered
will be sent to such Holder as soon as practicable  after the  Expiration  Date.
All Old  Notes  delivered  to the  Exchange  Agent  will be  deemed to have been
tendered unless otherwise indicated.

     Tenders of Old Notes pursuant to the Exchange Offer are irrevocable, except
that Old Notes  tendered  pursuant to the Exchange Offer may be withdrawn at any
time prior to the Expiration  Date. To be effective,  a written,  telegraphic or
facsimile  transmission  notice of  withdrawal  must be timely  received  by the
Exchange Agent at one of the addresses  specified on the first page hereof.  Any
such  notice of  withdrawal  must  specify  the  person  named in the  Letter of
Transmittal as having tendered Old Notes to be withdrawn, identify the Old Notes
to be  withdrawn  (including  the  principal  amount  of such Old  Notes,  where
certificates  for Old Notes have been  tendered)  specify the name in which such
Old Notes are registered, if different from that of the withdrawing Holder, must
include a statement that such Holder is withdrawing its election to have such

<PAGE>

Old Notes exchanged,  and must be signed by the Holder in the same manner as the
original  signature  on  the  Letter  of  Transmittal  (including  any  required
signature  guarantees) or be accompanied by evidence satisfactory to the Company
that the person withdrawing the tender has succeeded to the beneficial ownership
of the Old Notes being  withdrawn.  The Exchange  Agent will return the properly
withdrawn  Old Notes  promptly  following  receipt of notice of  withdrawal.  If
certificates  for Old Notes have been  delivered or otherwise  identified to the
Exchange Agent, then, prior to the release of such certificates, the withdrawing
Holder must also submit the serial numbers of the particular  certificates to be
withdrawn.  If Old Notes  have  been  tendered  pursuant  to the  procedure  for
book-entry  transfer,  any notice of withdrawal must specify the name and number
of the account at The Depository Trust Company to be credited with the withdrawn
Old Notes or otherwise  comply with The Depository  Trust Company's  procedures.
All  questions  as to the  validity,  form and  eligibility  (including  time of
receipt) of such notices will be determined by the Company,  whose determination
shall be final and binding on all parties.  Any Old Notes so  withdrawn  will be
deemed not to have been  validly  tendered  for  exchange  for  purposes  of the
Exchange  Offer.  Any Old Notes which have been  tendered for exchange but which
are not exchanged for any reason will be returned to the Holder thereof  without
cost to such  Holder  (or,  in the  case of Old  Notes  tendered  by  book-entry
transfer  into the Exchange  Agent's  account at The  Depository  Trust  Company
pursuant to the book-entry transfer  procedures  described above, such Old Notes
will be credited to an account  maintained with The Depository Trust Company for
the Old Notes) as soon as practicable after  withdrawal,  rejection of tender or
termination  of  the  Exchange  Offer.  Properly  withdrawn  Old  Notes  may  be
retendered  by  following  one of the  procedures  described  herein  and in the
Prospectus under "Procedures for Tendering Old Notes" at any time on or prior to
the Expiration Date.

ENDORSEMENTS;  GUARANTEE OF SIGNATURES.  If this Letter of Transmittal is signed

Holders of Old Notes listed and tendered hereby, no endorsements of certificates
or separate written instruments of transfer or exchange are required.

     If this  Letter  of  Transmittal  is  signed  by a  person  other  than the

Holders appear(s) on the Old Notes.

     If this  Letter  of  Transmittal,  any  certificates  or  separate  written
instruments  of  transfer  or  exchange  are  signed  by  trustees,   executors,
administrators, guardians, attorneys-in-fact, officers of corporations or others
acting  in a  fiduciary  or  representative  capacity,  such  persons  should so
indicate  when  signing,  and,  unless  waived by the Company,  proper  evidence
satisfactory to the Company of their authority so to act must be submitted.

     Endorsements on certificates or signatures on separate written  instruments
of transfer or exchange  required by this Instruction 3 must be guaranteed by an
Eligible Institution.

     Signatures  on this  Letter of  Transmittal  need not be  guaranteed  by an
Eligible Institution,  provided the Old Notes are tendered:  (i) by a registered
Holder  of such Old  Notes  and the  certificates  for New Notes to be issued in
exchange therefor are to be issued (or any untendered amount of Old Notes are to
be reissued) to the registered  Holder;  or (ii) for the account of any Eligible
Institution.

     4.  TRANSFER  TAXES.  The Company  shall pay all  transfer  taxes,  if any,
applicable to the transfer and exchange of Old Notes to it or its order pursuant
to the Exchange Offer. If, however,  New Notes are to be delivered to, or are to
be  registered  or issued in the name of, any person  other than the  registered
Holder of
<PAGE>

the Old Notes  tendered  hereby,  or if a transfer tax is imposed for any reason
other than the transfer of Old Notes to the Company or its order pursuant to the
Exchange  Offer,  the amount of any such transfer taxes (whether  imposed on the
registered  Holder or any other person) will be payable by the tendering Holder.
If satisfactory  evidence of payment of such taxes or exception therefrom is not
submitted  herewith the amount of such transfer taxes will be billed directly to
such tendering Holder.

     Except as  provided in this  Instruction  4, it will not be  necessary  for
transfer  tax  stamps to be affixed  to the Old Notes  listed in this  Letter of
Transmittal.

(including  time of receipt),  and  acceptance of Letters of  Transmittal or Old
Notes will be resolved by the  Company,  whose  determination  will be final and
binding. The Company reserves the absolute right to reject any or all Letters of
Transmittal  or tenders that are not in proper form or the  acceptance  of which
would, in the opinion of the Company's  counsel,  be unlawful.  The Company also
reserves the right to waive any irregularities or conditions of tender as to the
particular Old Notes covered by any Letter of  Transmittal or tendered  pursuant
to such letter either before or after the Expiration  Date  (including the right
to waive the  ineligibility  of any  Holder who seeks to tender Old Notes in the

period of time as the Company shall determine. None of the Company, the Exchange

defects or  irregularities in tenders or incur any liability for failure to give
any such notification.  The Company's interpretation of the terms and conditions
of the Exchange Offer as to any  particular  Old Notes  (including the Letter of
Transmittal and the instructions  thereto) either before or after the Expiration
Date shall be final and binding on all parties.

Debentures  due 2027 (the "New 8.875%  Debentures"  and,  together  with the New
8.50% Notes,  the "New  Notes"),  pursuant to an offering  registered  under the
Securities Act of 1933, as amended (the "Securities  Act"), for a like principal
amount of its issued and outstanding  8.50% Senior  Subordinated  Notes due 2007
(the "Old 8.50% Notes") or 8.875% Senior Subordinated  Debentures 2027 (the "Old
8.875%  Debentures"  and,  together with the Old 8.50% Notes,  the "Old Notes"),
respectively,  upon the terms and  subject  to the  conditions  set forth in the
Exchange Offer.

     PLEASE NOTE THAT THE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON
FEBRUARY , 1998, UNLESS EXTENDED.

     The Offer is not  conditioned  upon any  minimum  number of Old Notes being
tendered.

     We are the holder of record and/or  participant in the book-entry  transfer
facility  of Old Notes held by us for your  account.  A tender of such Old Notes
can be made only by us as the record holder and/or participant in the book-entry
transfer facility and pursuant to your  instructions.  The Letter of Transmittal
is  furnished  to you for your  information  only and  cannot  be used by you to
tender Old Notes held by us for your account.

     We request  instructions as to whether you wish to tender any or all of the
Old Notes held by us for your account  pursuant to the terms and  conditions  of
the Exchange  Offer. We also request that you confirm that we may on your behalf
make the representations contained in the Letter of Transmittal.

     Pursuant  to the  Letter of  Transmittal,  each  holder  of Old Notes  will
represent to the Company that (i) the New Notes  acquired in the Exchange  Offer
are being  obtained in the ordinary  course of business of the person  receiving
such New Notes,  whether or not such  person is such  holder,  (ii)  neither the
holder  of the Old  Notes  nor any  such  other  person  has an  arrangement  or
understanding  with any person to  participate in the  distribution  of such New
Notes, (iii) if the holder is not a broker-dealer or is a broker-dealer but will
not receive New Notes for its own account in exchange for Old Notes, neither the
holder nor any such other  person is engaged in or intends to  participate  in a
distribution  of the New Notes and (iv)  neither  the  holder nor any such other
person is an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act of 1933, as amended.  If the tendering  holder is a broker-dealer
(whether or not it is also an  "affiliate")  that will receive New Notes for its
own  account in  exchange  for Old Notes,  we will  represent  on behalf of such
broker-dealer that the Old Notes to be exchanged for the New Notes were acquired
by it as a result of market-making  activities or other trading activities,  and
acknowledge  on behalf of such  broker-dealer  that it will deliver a prospectus
meeting the

requirements  of the Act in  connection  with any resale of such New  Notes.  By
