               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 such
               Debenture 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 Trustee shall
               fix a  special  record  date for the  payment  of such  Defaulted
               Interest  which  shall  not be more than 15 nor less than 10 days
               prior to the date of the  proposed  payment  and not less than 10
               days  after  the  receipt  by the  Trustee  of the  notice of the
               proposed  payment.  The Trustee shall promptly notify the Company
               of such  special  record date and, in the name and at the expense
               of the Company,  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  Debentureholder
               at his or her address as it appears in the Debenture Register (as
               hereinafter defined), not less than 10 days prior to such special
               record  date.  Notice of the proposed  payment of such  Defaulted
               Interest and the special record date therefor  having been mailed
               as  aforesaid,  such  Defaulted  Interest  shall  be  paid to the
               persons in whose  names  such  Debentures  (or their  Predecessor
               Debentures)  are registered on such special record date and shall
               be no longer payable pursuant to the following clause (2).

               (2) The Company may make payment of any Defaulted Interest on any
               Debentures in any other lawful manner not  inconsistent  with the
               requirements of any securities  exchange on which such Debentures
               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
               payment shall be deemed practicable by the Trustee.

         Unless  otherwise  set  forth  in a  Board  Resolution  or one or  more
indentures   supplemental  hereto  establishing  the  terms  of  any  series  of

authenticated  and  delivered or disposed of such person shall have ceased to be
the Chairman, Vice Chairman,  President or a Vice President, or the Secretary or
an  Assistant  Secretary,  of the  Company,  as the case may be. The seal of the
Company may be in the form of a facsimile  of the seal of the Company and may be
impressed, affixed, imprinted or otherwise reproduced on the Debentures.

         Only  such   Debentures  as  shall  bear  thereon  a   Certificate   of
Authentication  substantially  in the  form  established  for  such  Debentures,
executed  manually  by an  authorized  signatory  of  the  Trustee,  or  by  any
Authenticating  Agent with respect to such Debentures,  shall be entitled to the
benefits of this  Indenture  or be valid or  obligatory  for any  purpose.  Such
certificate executed by the Trustee, or by any Authenticating Agent appointed by
the Trustee with respect to such Debentures,  upon any Debenture executed by the
Company shall be conclusive  evidence  that the Debenture so  authenticated  has
been duly  authenticated and made available for delivery  hereunder and that the
holder is entitled to the benefits of this Indenture.

         At any time and from time to time after the  execution  and delivery of
this Indenture, the Company may deliver Debentures of any series executed by the
Company to the Trustee for authentication,  together with a written order of the
Company for the  authentication  and delivery of such Debentures,  signed by its
President or any Vice  President and its  Treasurer or any Assistant  Treasurer,
and the Trustee in  accordance  with such written order shall  authenticate  and
make available for delivery such Debentures.

         In   authenticating   such  Debentures  and  accepting  the  additional
responsibilities  under this  Indenture  in  relation  to such  Debentures,  the
Trustee  shall be entitled to receive,  and  (subject to Section  7.01) shall be
fully protected in relying upon, an Opinion of Counsel stating that the form and
terms thereof have been  established  in conformity  with the provisions of this
Indenture.

         The Trustee shall not be required to  authenticate  such  Debentures if
the  issue  of such  Debentures  pursuant  to this  Indenture  will  affect  the
Trustee's  own  rights,  duties  or  immunities  under the  Debentures  and this
Indenture or otherwise in a manner  which is not  reasonably  acceptable  to the
Trustee.

         SECTION 2.05. Exchange of Debentures.  (a) Debentures of any series may
be exchanged  upon  presentation  thereof at the office or agency of the Company
designated  for such purpose in the Borough of Manhattan,  The City and State of
New York, for other Debentures of such series of authorized  denominations,  and
for a like aggregate principal amount, upon payment of a sum sufficient to cover
any tax or other  governmental  charge in relation  thereto,  all as provided in
this Section.  In respect of any  Debentures so  surrendered  for exchange,  the
Company shall execute,  the Trustee shall authenticate and such office or agency
shall make  available  for  delivery  in  exchange  therefor  the  Debenture  or
Debentures  of the same series  which the  Debentureholder  making the  exchange
shall be entitled to receive, bearing numbers not contemporaneously outstanding.

         (b) The  Company  shall  keep,  or cause to be kept,  at its  office or
agency  designated  for such purpose in the Borough of  Manhattan,  The City and
State of New York, or such other  location  designated by the Company a register
or registers (herein referred to as the "Debenture  Register") in which, subject
to such reasonable  regulations as it may prescribe,  the Company shall register
the Debentures  and the transfers of Debentures as in this Article  provided and
which at all reasonable  times shall be open for inspection by the Trustee.  The
registrar for the purpose of  registering  Debentures and transfer of Debentures
as herein  provided  shall be appointed as authorized by Board  Resolution  (the
"Debenture Registrar").

         Upon surrender for transfer of any Debenture at the office or agency of
the Company  designated  for such purpose in the Borough of Manhattan,  The City
and State of New York, the Company shall execute, the Trustee shall authenticate
and such office or agency shall make  available  for delivery in the name of the
transferee  or  transferees  a new Debenture or Debentures of the same series as
the Debenture presented for a like aggregate principal amount.

         All Debentures presented or surrendered for exchange or registration of
transfer,  as provided in this Section,  shall be accompanied (if so required by
the Company or the Debenture  Registrar) by a written  instrument or instruments
of transfer, in form



                                       14



satisfactory  to the Company or the  Debenture  Registrar,  duly executed by the
registered holder or by his duly authorized attorney in writing.

         (c) No service charge shall be made for any exchange or registration of
transfer of Debentures, or issue of new Debentures in case of partial redemption
of any series,  but the Company may require payment of a sum sufficient to cover
any tax or other governmental  charge in relation thereto,  other than exchanges
pursuant to Section 2.06, the second  paragraph of Section 3.03 and Section 9.04
not involving any transfer.

         (d) The  Company  shall  not be  required  (i) to  issue,  exchange  or
register the transfer of any Debentures during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of  redemption  of
less than all the  outstanding  Debentures  of the same series and ending at the
close of business on the day of such mailing,  nor (ii) to register the transfer
of or  exchange  any  Debentures  of any series or portions  thereof  called for
redemption.  The provisions of this Section 2.05 are, with respect to any Global
Debenture, subject to Section 2.11 hereof.

         SECTION  2.06.  Temporary   Debentures.   Pending  the  preparation  of
definitive  Debentures of any series,  the Company may execute,  and the Trustee
shall  authenticate  and  make  available  for  delivery,  temporary  Debentures
(printed,  lithographed  or  typewritten)  of any authorized  denomination,  and
substantially in the form of the definitive Debentures in lieu of which they are
issued, but with such omissions, insertions and variations as may be appropriate
for  temporary  Debentures,  all as  may be  determined  by the  Company.  Every
temporary  Debenture  of any series  shall be  executed  by the  Company  and be
authenticated by the Trustee upon the same conditions and in  substantially  the
same manner, and with like effect, as the definitive  Debentures of such series.
Without  unnecessary delay the Company will execute and will furnish  definitive
Debentures of such series and thereupon any or all temporary  Debentures of such
series may be surrendered in exchange  therefor (without charge to the holders),
at the office or agency of the Company designated for the purpose in the Borough
of Manhattan, The City and State of New York, and the Trustee shall authenticate
and such office or agency shall make available for delivery in exchange for such
temporary   Debentures  an  equal  aggregate   principal  amount  of  definitive
Debentures of such series,  unless the Company advises the Trustee to the effect
that  definitive  Debentures  need not be executed and  furnished  until further
notice from the Company.  Until so exchanged,  the temporary  Debentures of such
series shall be entitled to the same benefits under this Indenture as definitive
Debentures of such series authenticated and delivered hereunder.

         SECTION 2.07. Mutilated,  Destroyed, Lost or Stolen Debentures. In case
any temporary or definitive  Debenture  shall become  mutilated or be destroyed,
lost or stolen,  the Company  (subject to the next  succeeding  sentence)  shall
execute,  and  upon  its  request  the  Trustee  (subject  as  aforesaid)  shall
authenticate and make available for delivery, a new Debenture of the same series
bearing a number not contemporaneously outstanding,




                                       15



in exchange and substitution for the mutilated  Debenture,  or in lieu of and in
substitution for the Debenture so destroyed,  lost or stolen.  In every case the
applicant  for a substituted  Debenture  shall furnish to the Company and to the
Trustee  such  security or  indemnity as may be required by them to save each of
them harmless,  and, in every case of destruction,  loss or theft, the applicant
shall  also  furnish  to the  Company  and  to the  Trustee  evidence  to  their
satisfaction of the destruction,  loss or theft of the applicant's Debenture and
of the ownership  thereof.  The Trustee may  authenticate  any such  substituted
Debenture and make  available for delivery the same upon the written  request or
authorization  of  any  officer  of  the  Company.  Upon  the  issuance  of  any
substituted  Debenture,  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.  In case any  Debenture  which has  matured or is about to
mature shall become mutilated or be destroyed,  lost or stolen, the Company may,
instead of issuing a substitute  Debenture,  pay or authorize the payment of the
same (without surrender thereof except in the case of a mutilated  Debenture) if
the  applicant  for such payment shall furnish to the Company and to the Trustee
such  security or indemnity as they may require to save them  harmless,  and, in
case of destruction,  loss or theft, evidence to the satisfaction of the Company
and the Trustee of the  destruction,  loss or theft of such Debenture and of the
ownership thereof.

         Every  Debenture  issued  pursuant to the provisions of this Section in
substitution  for any Debenture  which is mutilated,  destroyed,  lost or stolen
shall constitute an additional contractual obligation of the Company, whether or
not the mutilated,  destroyed,  lost or stolen  Debenture  shall be found at any
time, or be enforceable by anyone,  and shall be entitled to all the benefits of
this Indenture equally and proportionately  with any and all other Debentures of
the same series duly issued  hereunder.  All Debentures  shall be held and owned
upon the express  condition  that the foregoing  provisions  are exclusive  with
respect to the  replacement or payment of mutilated,  destroyed,  lost or stolen
Debentures,  and shall  preclude (to the extent lawful) any and all other rights
or remedies, notwithstanding any law or statute existing or hereafter enacted to
the  contrary  with  respect  to  the   replacement  or  payment  of  negotiable
instruments or other securities without their surrender.

         SECTION 2.08.  Cancellation of Surrendered  Debentures.  All Debentures
surrendered for the purpose of payment, redemption,  exchange or registration of
transfer  shall, if surrendered to the Company or any paying agent, be delivered
to the Trustee for  cancellation,  or, if surrendered  to the Trustee,  shall be
canceled  by it, and no  Debentures  shall be issued in lieu  thereof  except as
expressly  required or permitted by any of the provisions of this Indenture.  On
written  request of the  Company,  the  Trustee  shall  deliver  to the  Company
canceled  Debentures held by the Trustee. If the Company shall otherwise acquire
any  of the  Debentures,  however,  such  acquisition  shall  not  operate  as a
redemption or  satisfaction of the  indebtedness  represented by such Debentures
unless and until the same are delivered to the Trustee for cancellation.




                                       16



         SECTION 2.09.  Provisions of Indenture and  Debentures for Sole Benefit
of Parties and Debentureholders. Nothing in this Indenture or in the Debentures,
express or implied,  shall give or be construed  to give to any person,  firm or
corporation,  other than the parties  hereto and the holders of the  Debentures,
any legal or  equitable  right,  remedy  or claim  under or in  respect  of this
Indenture, or under any covenant,  condition or provision herein contained;  all
such  covenants,  conditions  and  provisions  being for the sole benefit of the
parties hereto and of the holders of the Debentures.

         SECTION 2.10.  Appointment of  Authenticating  Agent. So long as any of
the Debentures of any series remain  outstanding  there may be an Authenticating
Agent for any or all such series of Debentures  which the Trustee shall have the
right to appoint. Said Authenticating Agent shall be authorized to act on behalf
of the Trustee to  authenticate  Debentures of such series issued upon exchange,
transfer or partial redemption thereof, and Debentures so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if  authenticated  by the Trustee  hereunder.  All references in
this  Indenture to the  authentication  of  Debentures  by the Trustee  shall be
deemed to include  authentication  by an  Authenticating  Agent for such  series
except for  authentication  upon  original  issuance or pursuant to Section 2.07
hereof. Each  Authenticating  Agent shall be acceptable to the Company and shall
be a  corporation  which has a combined  capital and surplus,  as most  recently
reported or  determined  by it,  sufficient  under the laws of any  jurisdiction
under which it is organized or in which it is doing  business to conduct a trust
business,  and which is  otherwise  authorized  under such laws to conduct  such
business  and is  subject  to  supervision  or  examination  by Federal or State
authorities.  If at any time any Authenticating Agent shall cease to be eligible
in accordance with these provisions, it shall resign immediately.

         Any  Authenticating  Agent may at any time  resign  by  giving  written
notice of resignation to the Trustee and to the Company.  The Trustee may at any
time (and  upon  request  by the  Company  shall)  terminate  the  agency of any
Authenticating   Agent  by  giving   written   notice  of  termination  to  such
Authenticating  Agent  and to the  Company.  Upon  resignation,  termination  or
cessation of eligibility of any Authenticating Agent, the Trustee may appoint an
eligible successor Authenticating Agent acceptable to the Company. Any successor
Authenticating Agent, upon acceptance of its appointment hereunder, shall become
vested with all the rights, powers and duties of its predecessor hereunder as if
originally named as an Authenticating Agent pursuant hereto.

         SECTION 2.11.  Global  Debenture.  (a) If the Company  shall  establish
pursuant to Section 2.01 that the  Debentures  of a particular  series are to be
issued as one or more Global Debentures,  then the Company shall execute and the
Trustee shall, in accordance with Section 2.04, authenticate and deliver, one or
more Global Debentures which (i) shall represent, and shall be denominated in an
aggregate  amount  equal  to  the  aggregate  principal  amount  of,  all of the
Outstanding  Debentures of such series,  (ii) shall be registered in the name of
the Depositary or its nominee, (iii) shall be delivered by the




                                       17



Trustee to the Depositary or pursuant to the  Depositary's  instruction and (iv)
shall bear a legend substantially to the following effect:  "Except as otherwise
provided in Section 2.11 of the Indenture, this Debenture may be transferred, in
whole  but not in  part,  only to  another  nominee  of the  Depositary  or to a
successor Depositary or to a nominee of such successor Depositary."

         (b)   Notwithstanding  the  provisions  of  Section  2.05,  the  Global
Debenture  of a series may be  transferred,  in whole but not in part and in the
manner  provided in Section 2.05,  only to another nominee of the Depositary for
such series,  or to a successor  Depositary for such series selected or approved
by the Company or to a nominee of such successor Depositary.

         (c) If at any time the Depositary  for a series of Debentures  notifies
the Company that it is unwilling  or unable to continue as  Depositary  for such
series  or if at any time the  Depositary  for such  series  shall no  longer be
registered  or in good  standing  under the  Exchange  Act, or other  applicable
statute  or  regulation  and a  successor  Depositary  for  such  series  is not
appointed by the Company  within 90 days after the Company  receives such notice
or becomes aware of such condition,  as the case may be, this Section 2.11 shall
no longer be  applicable  to the  Debentures of such series and the Company will
execute,  and subject to Section 2.05,  the Trustee will  authenticate  and make
available for delivery  Debentures of such series in definitive  registered form
without  coupons,  in authorized  denominations,  and in an aggregate  principal
amount equal to the principal amount of the Global  Debentures of such series in
exchange for such Global  Debenture.  In  addition,  the Company may at any time
determine  that the  Debentures of any series shall no longer be  represented by
one or more Global Debentures and that the provisions of this Section 2.11 shall
no longer apply to the Debentures of such series. In such event the Company will
execute and subject to Section 2.05,  the Trustee,  upon receipt of an Officers'
Certificate  evidencing such determination by the Company, will authenticate and
deliver Debentures of such series in definitive registered form without coupons,
in authorized  denominations,  and in an aggregate principal amount equal to the
principal  amount of the Global  Debentures  of such series in exchange for such
Global  Debentures.  Upon  the  exchange  of  the  Global  Debentures  for  such
Debentures  in  definitive   registered  form  without  coupons,  in  authorized
denominations,  the Global  Debentures  shall be canceled by the  Trustee.  Such
Debentures  in  definitive  registered  form issued in  exchange  for the Global
Debentures  pursuant to this Section  2.11(c)  shall be registered in such names
and in such authorized denominations as the Depositary, pursuant to instructions
from its direct or  indirect  participants  or  otherwise,  shall  instruct  the
Trustee.  The Trustee  shall  deliver  such  Debentures  to the  Depositary  for
delivery to the persons in whose names such Debentures are so registered.

         SECTION 2.12. CUSIP Numbers.  The Company in issuing the Debentures may
use "CUSIP" and "CINS" numbers (if then generally in use), and the Trustee shall
use CUSIP numbers or CINS numbers,  as the case may be, in notices of redemption
or




                                       18



exchange as a convenience to  Debentureholders  and no  representation  shall be
made as to the  correctness  of such numbers either as printed on the Debentures
or as contained in any notice of redemption or exchange.


                                    ARTICLE 3
              REDEMPTION OF DEBENTURES AND SINKING FUND PROVISIONS

         SECTION  3.01.  Redemption  of  Debentures.  The Company may redeem the
Debentures  of any  series  issued  hereunder  on and  after  the  dates  and in
accordance  with the terms  established for such series pursuant to Section 2.01
hereof.

         SECTION  3.02.  Notice of  Redemption.  (a) In case the  Company  shall
desire to exercise such right to redeem all or, as the case may be, a portion of
the Debentures of any series in accordance  with the right reserved so to do, it
shall give notice of such redemption to holders of the Debentures of such series
to be  redeemed  by  mailing,  first  class  postage  prepaid,  a notice of such
redemption not less than 30 days and not more than 60 days before the date fixed
for  redemption  of that series to such holders at their last  addresses as they
shall  appear upon the  Debenture  Register.  Any notice  which is mailed in the
manner herein provided shall be  conclusively  presumed to have been duly given,
whether or not the registered holder receives the notice.  In any case,  failure
duly to give such notice to the holder of any Debenture of any series designated
for  redemption  in whole or in part,  or any  defect in the  notice,  shall not
affect  the  validity  of the  proceedings  for  the  redemption  of  any  other
Debentures of such series or any other series.  In the case of any redemption of
Debentures  prior  to the  expiration  of any  restriction  on  such  redemption
provided in the terms of such  Debentures  or elsewhere in this  Indenture,  the
Company  shall  furnish the Trustee  with an  Officers'  Certificate  evidencing
compliance with any such restriction.

         Each  such  notice  of  redemption  shall  specify  the date  fixed for
redemption and the redemption price at which Debentures of that series are to be
redeemed,  and  shall  state  that  payment  of the  redemption  price  of  such
Debentures to be redeemed will be made at the office or agency of the Company in
the Borough of Manhattan,  the City and State of New York, upon presentation and
surrender  of such  Debentures,  that  interest  accrued  to the date  fixed for
redemption  will be paid as specified  in said notice,  that from and after said
date  interest  will  cease to accrue and that the  redemption  is for a sinking
fund, if such is the case. If less than all the Debentures of a series are to be
redeemed,  the notice to the holders of Debentures of that series to be redeemed
in whole or in part shall specify the
particular Debentures to be so redeemed. In case any Debenture is to be redeemed
in part only, the notice which relates to such Debenture shall state the portion
of the  principal  amount  thereof to be  redeemed,  and shall state that on and
after the redemption date,





                                       19



upon surrender of such  Debenture,  a new Debenture or Debentures of such series
in principal amount equal to the unredeemed portion thereof will be issued.

         (b) If less than all the Debentures of a series are to be redeemed, the
Company  shall give the Trustee at least 45 days'  notice in advance of the date
fixed for redemption as to the aggregate  principal  amount of Debentures of the
series to be redeemed, and thereupon the Trustee shall select, by lot or in such
other manner as it shall deem  appropriate  and fair in its discretion and which
may provide  for the  selection  of a portion or  portions  (equal to $50 or any
integral  multiple  thereof) of the  principal  amount of such  Debentures  of a
denomination larger than $50, the Debentures to be redeemed and shall thereafter
promptly  notify the Company in writing of the numbers of the  Debentures  to be
redeemed, in whole or in part.

         The  Company  may, if and  whenever  it shall so elect,  by delivery of
instructions  signed  on its  behalf  by its  President  or any Vice  President,
instruct  the  Trustee  or any  paying  agent  to  call  all or any  part of the
Debentures  of a  particular  series  for  redemption  and  to  give  notice  of
redemption  in the manner set forth in this  Section,  such  notice to be in the
name of the Company or its own name as the Trustee or such paying agent may deem
advisable.  In any  case in which  notice  of  redemption  is to be given by the
Trustee or any such  paying  agent,  the  Company  shall  deliver or cause to be
delivered to, or permit to remain with, the Trustee or such paying agent, as the
case may be,  such  Debenture  Register,  transfer  books or other  records,  or
suitable copies or extracts therefrom,  sufficient to enable the Trustee or such
paying  agent  to give  any  notice  by mail  that  may be  required  under  the
provisions of this Section.

         SECTION 3.03.  Debentures Due and Payable.  (a) If the giving of notice
of redemption  shall have been  completed as above  provided,  the Debentures or
portions of  Debentures  of the series to be redeemed  specified  in such notice
shall  become due and payable on the date and at the place stated in such notice
at the applicable  redemption price,  together with interest accrued to the date
fixed for redemption  and interest on such  Debentures or portions of Debentures
shall  cease to accrue on and after the date  fixed for  redemption,  unless the
Company  shall  default in the  payment  of such  redemption  price and  accrued
interest with respect to any such Debenture or portion thereof.  On presentation
and surrender of such  Debentures  on or after the date fixed for  redemption at
the place of payment specified in the notice,  said Debentures shall be paid and
redeemed at the  applicable  redemption  price for such  series,  together  with
interest accrued thereon to the date fixed for redemption (but if the date fixed
for redemption is an Interest Payment Date, the interest  installment payable on
such date shall be payable to the registered  holder at the close of business on
the applicable record date pursuant to Section 2.03).

         (b) Upon  presentation  of any  Debenture of such series which is to be
redeemed  in  part  only,  the  Company  shall  execute  and the  Trustee  shall
authenticate  and the office or



                                       20


agency where the Debenture is presented shall make available for delivery to the
holder thereof,  at the expense of the Company, a new Debenture or Debentures of
the same series,  of authorized  denominations  in principal amount equal to the
unredeemed portion of the Debenture so presented.

         SECTION 3.04. Sinking Funds for Debentures.  The provisions of Sections
3.04,  3.05 and 3.06 shall be applicable to any sinking fund for the  retirement
of  Debentures of a series,  except as otherwise  specified as  contemplated  by
Section 2.01 for Debentures of such series.

         The minimum  amount of any sinking  fund  payment  provided  for by the
terms of Debentures of any series is herein referred to as a "mandatory  sinking
fund payment",  and any payment in excess of such minimum amount provided for by
the terms of  Debentures  of any series is herein  referred  to as on  "optional
sinking  fund  payment".  If  provided  for by the terms of  Debentures  for any
series,  the cash amount of any sinking fund payment may be subject to reduction
as provided in Section  3.05.  Each sinking fund payment shall be applied to the
redemption  of  Debentures  of any  series  as  provided  for by  the  terms  of
Debentures of such series.

         SECTION 3.05.  Satisfaction  of Sinking Fund Payments With  Debentures.
The Company (i) may deliver  outstanding  Debentures of a series (other than any
previously called for redemption) and (ii) may apply as a credit Debentures of a
series which have been redeemed  either at the election of the Company  pursuant
to the terms of such Debentures or through the application of permitted optional
sinking fund payments pursuant to the terms of such Debentures,  in each case in
satisfaction  of all or any part of any sinking fund payment with respect to the
Debentures  of such  series  required  to be made  pursuant to the terms of such
Debentures  as  provided  for by the terms of such  series;  provided  that such
Debentures  have not been  previously  so  credited.  Such  Debentures  shall be
received and credited  for such purpose by the Trustee at the  redemption  price
specified in such  Debentures  for redemption  through  operation of the sinking
fund and the amount of such sinking fund payment shall be reduced accordingly.

         SECTION 3.06.  Redemption of Debentures for Sinking Fund. Not less than
45 days prior to each sinking  fund  payment date for any series of  Debentures,
the Company will deliver to the Trustee an Officers' Certificate  specifying the
amount of the next ensuing  sinking fund payment for that series pursuant to the
terms for that series, the portion thereof,  if any, which is to be satisfied by
delivering and crediting  Debentures of that series pursuant to Section 3.05 and
the basis for such credit and will,  together with such  Officers'  Certificate,
deliver to the Trustee any Debentures to be so delivered.  Not less than 30 days
before  each such  sinking  fund  payment  date the  Trustee  shall  select  the
Debentures  to be redeemed  upon such  sinking  fund  payment date in the manner
specified in Section 3.02 and cause notice of the redemption thereof to be given
in the name of and at the  expense  of the  Company in the  manner  provided  in
Section 3.02. Such notice



                                       21



having been duly given, the redemption of such Debentures shall be made upon the
terms and in the manner stated in Section 3.03.



                                    ARTICLE 4
                       PARTICULAR COVENANTS OF THE COMPANY

The Company covenants and agrees for each series of the Debentures as follows:

         SECTION  4.01.  Payment  of  Principal  of (And  Premium,  if any)  and
Interest on Debentures.  The Company will duly and punctually pay or cause to be
paid the  principal of (and premium,  if any) and interest on the  Debentures of
that  series  at the  time and  place  and in the  manner  provided  herein  and
established with respect to such Debentures.

         SECTION 4.02. Maintenance of Office or Agent for Payment of Debentures,
Designation of Office or Agency for Payment, Registration, Transfer and Exchange
of Debentures.  So long as any series of the Debentures remain outstanding,  the
Company agrees to maintain an office or agency in the Borough of Manhattan,  The
City and State of New York,  with  respect to each such series and at such other
location or locations  as may be  designated  as provided in this Section  4.02,
where  (i)  Debentures  of  that  series  may be  presented  for  payment,  (ii)
Debentures  of that  series may be  presented  as herein  above  authorized  for
registration of transfer and exchange,  and (iii) notices and demands to or upon
the Company in respect of the  Debentures of that series and this  Indenture may
be given or served,  such designation to continue with respect to such office or
agency until the Company  shall,  by written notice signed by its President or a
Vice  President  and  delivered to the Trustee,  designate  some other office or
agency for such  purposes or any of them.  If at any time the Company shall fail
to  maintain  any such  required  office or agency or shall fail to furnish  the
Trustee with the address thereof, such presentations, notices and demands may be
made or served at the  Corporate  Trust Office of the  Trustee,  and the Company
hereby  appoints  the  Trustee as its agent to receive  all such  presentations,
notices and demands.

         SECTION 4.03.  Duties of Paying Agent;  Company as Payment  Agent;  and
Holding  Sums of Trust.  (a) If the  Company  shall  appoint  one or more paying
agents for all or any series of the  Debentures,  other  than the  Trustee,  the
Company will cause each such paying agency to execute and deliver to the Trustee
an instrument  in which such agent shall agree with the Trustee,  subject to the
provisions of this Section:


                  (1) that it will  hold all sums  held by it as such  agent for
                  the  payment  of the  principal  of (and  premium,  if any) or
                  interest on the  Debentures of that series  (whether such sums
                  have been paid to it by the Company or by any


                                       22



                  other obligor of such  Debentures) in trust for the benefit of
                  the persons entitled thereto:

                  (2)  that it will  give  the  Trustee  written  notice  of any
                  failure  by the  Company  (or by any  other  obligor  of  such
                  Debentures)  to make  any  payment  of the  principal  of (and
                  premium,  if any) or interest on the Debentures of that series
                  when the same shall be due and payable;

                  (3) that it will,  at any time during the  continuance  of any
                  failure  referred to in the preceding  paragraph (a)(2) above,
                  upon the written request of the Trustee,  forthwith pay to the
                  Trustee all sums so held in trust by such paying agent; and

                  (4) that it will  perform all other  duties of paying agent as
                  set forth in this Indenture.

         (b) If the Company  shall act as its own paying  agent with  respect to
any  series  of the  Debentures,  it  will on or  before  each  due  date of the
principal of (and premium, if any) or interest on Debentures of that series, set
aside,  segregate  and hold in trust for the  benefit  of the  persons  entitled
thereto a sum sufficient to pay such principal (and premium, if any) or interest
so becoming  due on  Debentures  of that series until such sums shall be paid to
such  persons or  otherwise  disposed of as herein  provided  and will  promptly
notify in writing the Trustee of such action, or any failure (by it or any other
obligor on such Debentures) to take such action. Whenever the Company shall have
one or more paying agents for any series of Debentures,  it will,  prior to each
due date of the principal of (and premium, if any) or interest on any Debentures
of that  series,  deposit  with the  paying  agent a sum  sufficient  to pay the
principal (and premium, if any) or interest so becoming due, such sum to be held
in trust for the benefit of the persons  entitled to such principal,  premium or
interest,  and  (unless  such paying  agent is the  Trustee)  the  Company  will
promptly notify the Trustee of its action or failure so to act.

         (c) Anything in this Section to the contrary  notwithstanding,  (i) the
agreement  to hold sums in trust as provided  in this  Section is subject to the
provisions  of Section  11.04,  and (ii) the  Company  may at any time,  for the
purpose of obtaining the satisfaction and discharge of this Indenture or for any
other  purpose,  pay, or direct any paying agent to pay, to the Trustee all sums
held in trust by the Company or such paying  agent,  such sums to be held by the
Trustee  upon the same terms and  conditions  as those upon which such sums were
held by the Company or such paying  agent;  and, upon such payment by any paying
agent to the  Trustee,  such paying  agent  shall be  released  from all further
liability with respect to such money.

         SECTION  4.04.  Appointment  to Fill Vacancy in Office of Trustee.  The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the




                                       23


manner provided in Section 7.10, a Trustee,  so that there shall at all times be
a Trustee hereunder.

       DEBENTUREHOLDER'S LISTS AND REPORTS BY THE COMPANY AND THE TRUSTEE

         SECTION 5.01.  Company to Furnish  Trustee  Information as to Names and
Addresses  of  Debentures.  The Company will furnish or cause to be furnished to
the Trustee (a) on a quarterly  basis on each regular record date (as defined in
Section 2.03) a list, in such form as the Trustee may reasonably require, of the
names and  addresses  of the  holders of each  series of  Debentures  as of such
regular  record  date,  provided,  that the Company  shall not be  obligated  to
furnish or cause to furnish such list at any time that the list shall not differ
in any respect from the most recent list furnished to the Trustee by the Company
and (b) at such other times as the Trustee may request in writing within 30 days
after the receipt by the Company of any such request, a list of similar form and
content  as of a date not more  than 15 days  prior  to the  time  such  list is
furnished;  provided, however, no such list need be furnished for any series for
which the Trustee shall be the Debenture Registrar.

         SECTION 5.02. Trustee to Preserve Information as to Names and Addresses
of Debentureholders.  (a) The Trustee shall preserve, in as current a form as is
reasonably  practicable,  all  information  as to the names and addresses of the
holders of  Debentures  contained  in the most  recent list  furnished  to it as
provided  in  Section  5.01 and as to the  names and  addresses  of  holders  of
Debentures  received by the Trustee in its capacity as Debenture  Registrar  (if
acting in such capacity).

         (b) The Trustee may  destroy  any list  furnished  to it as provided in
Section 5.01 upon receipt of a new list so furnished.

         (c)  In  case  three  or  more  holders  of   Debentures  of  a  series
(hereinafter  referred to as "applicants") apply in writing to the Trustee,  and
furnish to the Trustee  reasonable  proof that each such  applicant  has owned a
Debenture  for a  period  of at  least  six  months  preceding  the date of such
application,   and  such  application  states  that  the  applicants  desire  to
communicate  with other  holders of  Debentures of such series or holders of all
Debentures  with  respect to their  rights  under this  Indenture  or under such
Debentures,  and is  accompanied  by a copy  of  the  form  of  proxy  or  other
communication which such applicants propose to transmit,  then the Trustee shall
within  five  business  days  after  the  receipt  of such  application,  at its
election, either:





                                       24



                  (1)  afford  to  such  applicants  access  to the  information
                  preserved  at the time by the Trustee in  accordance  with the
                  provisions of subsection (a) of this Section 5.02; or

                  (2) inform such  applicants  as to the  approximate  number of
                  holders of Debentures of such series or of all Debentures,  as
                  the case may be,  whose  names  and  addresses  appear  in the
                  information   preserved  at  the  time  by  the  Trustee,   in
                  accordance  with  the  provisions  of  subsection  (a) of this
                  Section  5.02,  and as to the  approximate  cost of mailing to
                  such   Debentureholders   the   form   of   proxy   or   other
                  communication, if any, specified in such application.

         (d) If the Trustee shall elect not to afford such applicants  access to
such  information,   the  Trustee  shall,  upon  the  written  request  of  such
applicants, mail to each holder of such series or of all Debentures, as the case
may be, whose name and address appears in the information  preserved at the time
by the Trustee in  accordance  with the  provisions  of  subsection  (a) of this
Section  5.02,  a copy of the  form of proxy  or  other  communication  which is
specified in such  request,  with  reasonable  promptness  after a tender to the
Trustee  of the  material  to be mailed and of  payment,  or  provision  for the
payment,  of the reasonable  expenses of mailing,  unless within five days after
such  tender,  the  Trustee  shall  mail to such  applicants  and file  with the
Securities and Exchange Commission (the  "Commission"),  together with a copy of
the  material  to be mailed,  a written  statement  to the effect  that,  in the
opinion of the Trustee,  such mailing would be contrary to the best interests of
the holders of Debentures of such series or of all  Debentures,  as the case may
be, or would be in violation of  applicable  law. Such written  statement  shall
specify the basis of such opinion.  If the Commission,  after  opportunity for a
hearing upon the objections  specified in the written statement so filed,  shall
enter an order refusing to sustain any of such objections or if, after the entry
of an order  sustaining one or more of such  objections,  the  Commission  shall
find,  after notice and  opportunity  for hearing,  that all the  objections  so
sustained have been met and shall enter an order so declaring, the Trustee shall
mail  copies  of such  material  to all such  Debentureholders  with  reasonable
promptness  after  the  entry of such  order  and the  renewal  of such  tender;
otherwise,  the  Trustee  shall be relieved  of any  obligation  or duty to such
applicants respecting their application.

         (e) Each and every holder of the  Debentures,  by receiving and holding
the same,  agrees with the Company and the Trustee  that neither the Company nor
the  Trustee  nor any paying  agent nor any  Debenture  Registrar  shall be held
accountable by reason of the disclosure of any such  information as to the names
and addresses of the holders of Debentures in accordance  with the provisions of
subsection  (b) of this  Section,  regardless  of the  source  from  which  such
information was derived,  and that the Trustee shall not be held  accountable by
reason of mailing any material  pursuant to a request made under said subsection
(b).

the Trustee is for informational purposes only and the Trustee's receipt of such

for in this  Indenture  as may be  required  from time to time by such rules and
regulations.

                  individual capacity,  on the date of such report, with a brief

                  thereof, if any) which it has not previously reported;

                  (7) any additional  issue of Debentures  which the Trustee has

                  Debentures or the Debentures of any series,






                                       27



                  except any action in respect of a default, notice of which has
                  been  or is to be  withheld  by  it  in  accordance  with  the
                  provisions of Section 6.07.

         (b) The Trustee shall transmit by mail, first class postage prepaid, to
the  Debentureholders,  as their names and  addresses  appear upon the Debenture
Register,  a brief  report  with  respect  to the  character  and  amount of any
advances (and if the Trustee elects so to state, the  circumstances  surrounding
the  making  thereof)  made by the  Trustee  as such  since the date of the last
report transmitted  pursuant to the provisions of subsection (a) of this Section

of this Indenture), for the reimbursement of which it claims or may claim a lien
or charge  prior to that of the  Debentures  of any series on  property or funds
held or collected  by it as Trustee,  and which it has not  previously  reported

aggregate  more than 10% of the  principal  amount of  Debentures of such series
outstanding  at such time,  such report to be  transmitted  within 90 days after
such time.

         (c) A copy of each such report shall, at the time of such  transmission
to Debentureholders,  be filed by the Trustee with the Company,  with each stock
exchange upon which any  Debentures  are listed (if so listed) and also with the
Commission.  The Company agrees to notify the Trustee when any Debentures become
listed on any stock exchange.

                  Code in respect of the Company and shall continue  undismissed
                  for a period  of 90 days or an order  for  relief in such case
                  shall  have  been  entered;  or a  decree  or order of a court
                  having  jurisdiction  in the premises  shall have been entered
                  for the  appointment on the ground of insolvency or bankruptcy
                  of a  receiver  or  custodian  or  liquidator  or  trustee  or
                  assignee in  bankruptcy or insolvency of the Company or of its
                  property, or for the winding up or liquidation of its affairs,
                  and  such  decree  or  order  shall  have  remained  in  force
                  unvacated and unstayed for a period of 90 days; or

                  (5) the Company shall institute  proceedings to be adjudicated
                  a  voluntary  bankrupt,  or shall  consent  to the filing of a
                  bankruptcy  proceeding against it, or shall file a petition or
                  answer or consent seeking liquidation or reorganization  under
                  the Federal  Bankruptcy  Code or any other similar  applicable
                  Federal  or State law,  or shall  consent to the filing of any
                  such  petition,  or shall  consent to the  appointment  on the
                  ground of  insolvency or bankruptcy of a receiver or custodian
                  or   liquidator  or  trustee  or  assignee  in  bankruptcy  or
                  insolvency  of  it  or of  its  property,  or  shall  make  an
                  assignment for the benefit of creditors.






                                       29



         (b) In each and  every  such  case,  unless  the  principal  of all the
Debentures of that series shall have already become due and payable,  either the
Trustee or the holders of not less than 25% in aggregate principal amount of the
Debentures of that series then  outstanding  hereunder,  by notice in writing to
the Company (and to the Trustee if given by such Debentureholders),  may declare
the  principal  of all the  Debentures  of  that  series  to be due and  payable
immediately,  and upon any such  declaration  the same shall become and shall be
immediately  due and payable,  anything  contained  in this  Indenture or in the
Debentures of that series or established with respect to that series pursuant to
Section 2.01 hereof to the contrary notwithstanding.

         (c) Section 6.01(b),  however,  is subject to the condition that if, at
any time after the principal of the Debentures of that series shall have been so
declared due and  payable,  and before any judgment or decree for the payment of
the moneys due shall have been obtained or entered as hereinafter provided,  the
Company shall pay or shall deposit with the Trustee a sum  sufficient to pay all
matured  installments of interest upon all the Debentures of that series and the
principal of (and  premium,  if any, on) any and all  Debentures  of that series
which shall have become due otherwise than by  acceleration  (with interest upon
such  principal  and  premium,  if any,  and, to the extent that such payment is
enforceable under applicable law, upon overdue installments of interest,  at the
rate per annum  expressed in the  Debentures  of that series to the date of such
payment or deposit) and the amount  payable to the Trustee  under  Section 7.06,
and any and all  defaults  under the  Indenture,  other than the  nonpayment  of
principal on  Debentures of that series which shall not have become due by their
terms,  shall have been  remedied or waived as provided in Section 6.06 then and
in every such case the holders of a majority in  aggregate  principal  amount of
the Debentures of that series then  outstanding  (subject to, in the case of any
series of  Debentures  held as trust  assets of a AES Trust and with  respect to
which a Security  Exchange  has not  theretofore  occurred,  such consent of the
holders of the Preferred  Securities and the Common Securities of such AES Trust
as may be required under the Declaration of Trust of such AES Trust), by written
notice to the Company and to the Trustee, may rescind and annul such declaration
and its  consequences  with  respect to that series of  Debentures;  but no such
rescission and annulment shall extend to or shall affect any subsequent default,
or shall impair any right consequent thereon.

         (d) In case the Trustee shall have  proceeded to enforce any right with
respect to Debentures of that series under this  Indenture and such  proceedings
shall  have  been  discontinued  or  abandoned  because  of such  rescission  or
annulment or for any other reason or shall have been determined adversely to the
Trustee,  then and in every  such  case the  Company  and the  Trustee  shall be
restored  respectively to their former positions and rights  hereunder,  and all
rights,  remedies  and powers of the Company and the Trustee  shall  continue as
though no such proceedings had been taken.






                                       30



         (e) If, prior to a Security  Exchange with respect to the Debentures of
any series,  a Default with respect to the  Debentures of such series shall have
occurred,  the Company  expressly  acknowledges that under the circumstances set
forth in the applicable Declaration of Trust, any holder of Preferred Securities
of the  applicable  AES Trust may  enforce  directly  against  the  Company  the
applicable Property Trustee's rights hereunder.  In furtherance of the foregoing
and for the avoidance of any doubt,  the Company  acknowledges  that,  under the
circumstances  described in the applicable Declaration of Trust, any such holder
of Preferred  Securities,  in its own name,  in the name of the  applicable  AES
Trust or in the name of the holders of the Preferred  Securities  issued by such
AES Trust,  may  institute or cause to be  instituted a  proceeding,  including,
without  limitation,  any suit in equity,  an action at law or other judicial or
administrative  proceeding,  to enforce the applicable Property Trustee's rights
hereunder  directly  against the Company as issuer of the  applicable  series of
Debentures,  and may prosecute such proceeding to judgment or final decree,  and
enforce the same against the Company.

         SECTION 6.02. Covenant of Company to Pay to Trustee Whole Amount Due on
Debentures  on Default in Payment of Interest or  Principal  (and  Premiums,  if
any).  (a) The Company  covenants  that (1) in case default shall be made in the
payment of any installment of interest on any of the Debentures of a series,  or
any payment  required by any sinking or analogous fund  established with respect
to that series as and when the same shall have become due and payable,  and such
default shall have  continued  for a period of 10 business  days, or (2) in case
default  shall be made in the payment of the  principal of (or premium,  if any,
on) any of the  Debentures  of a series  when the same shall have become due and
payable,  whether upon maturity of the Debentures of a series or upon redemption
or upon declaration or otherwise,  then, upon demand of the Trustee, the Company
will pay to the  Trustee,  for the benefit of the holders of the  Debentures  of
that series, the whole amount that then shall have become due and payable on all
such Debentures for principal (and premium, if any) or interest, or both, as the
case may be, with interest upon the overdue principal (and premium,  if any) and
(to the extent that payment of such interest is enforceable under applicable law
and  without  duplication  of any  other  amounts  paid  by the  Company  or the
applicable AES Trust in respect  thereof) upon overdue  installments of interest
at the rate per annum  expressed  in the  Debentures  of that  series;  and,  in
addition thereto,  such further amount as shall be sufficient to cover the costs
and expenses of collection,  and the amount payable to the Trustee under Section
7.06.

         (b) In case the Company  shall fail  forthwith to pay such amounts upon
such demand,  the Trustee,  in its own name and as trustee of an express  trust,
shall be entitled and empowered to institute any action or proceedings at law or
in equity for the  collection  of the sums so due and unpaid,  and may prosecute
any such action or proceeding  to judgment or final decree,  and may enforce any
such  judgment or final  decree  against the Company or other  obligor  upon the
Debentures of that series and collect in the manner




                                       31



provided by law out of the  property of the  Company or other  obligor  upon the
Debentures of that series wherever situated the moneys adjudged or decreed to be
payable.

         (c) In case of any receivership,  insolvency, liquidation,  bankruptcy,
reorganization,   readjustment,   arrangement,  composition  or  other  judicial
proceedings affecting the Company, any other obligor on such Debentures,  or the
creditors or property of either,  the Trustee  shall have the power to intervene
in such  proceedings  and take any action  therein  that may be permitted by the
court and shall (except as may be otherwise provided by law) be entitled to file
such  proofs of claim and other  papers and  documents  as may be  necessary  or
advisable  in order to have the  claims of the  Trustee  and of the  holders  of
Debentures  of such series  allowed for the entire amount due and payable by the
Company or such other obligor under the Indenture at the date of  institution of
such proceedings and for any additional  amount which may become due and payable
by the Company or such other obligor after such date, and to collect and receive
any moneys or other property  payable or  deliverable on any such claim,  and to
distribute  the same after the  deduction  of the amount  payable to the Trustee
under  Section  7.06;  and any  receiver,  assignee or trustee in  bankruptcy or
reorganization is hereby authorized by each of the holders of Debentures of such
series to make such payments to the Trustee,  and, in the event that the Trustee
shall consent to the making of such payments directly to such  Debentureholders,
to pay to the Trustee any amount due it under Section 7.06.

         (d) All rights of action and of asserting  claims under this Indenture,
or under any of the terms established with respect to Debentures of that series,
may be enforced by the Trustee without the possession of any of such Debentures,
or the production thereof at any trial or other proceeding relative thereto, and
any such suit or  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 payment to the  Trustee of any  amounts due under  Section
7.06,  be for the  ratable  benefit  of the  holders of the  Debentures  of such
series.

         In case of an  Event  of  Default  hereunder,  the  Trustee  may in its
discretion  proceed  to protect  and  enforce  the  rights  vested in it by this
Indenture by such  appropriate  judicial  proceedings  as the Trustee shall deem
most  effectual to protect and enforce any of such  rights,  either at law or in
equity or in bankruptcy or otherwise,  whether for the specific  enforcement  of
any covenant or agreement  contained in the  Indenture or in aid of the exercise
of any power  granted  in this  Indenture,  or to  enforce  any  other  legal or
equitable right vested in the Trustee by this Indenture or by law.

         Nothing  herein  contained  shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any  Debentureholder any
plan of  reorganization,  arrangement,  adjustment or composition  affecting the
Debentures  of that series or the rights of any holder  thereof or to  authorize
the Trustee to vote in respect of the claim of any  Debentureholder  in any such
proceeding.





                                       32



         SECTION 6.03.  Application of Moneys  Collected by Trustee.  Any moneys
collected  by the Trustee  pursuant to Section 6.02 with respect to a particular
series of  Debentures  shall be applied in the order  following,  at the date or
dates fixed by the Trustee  and, in case of the  distribution  of such moneys on
account of principal (or premium, if any) or interest,  upon presentation of the
several  Debentures of that series,  and stamping  thereon the payment,  if only
partially paid, and upon surrender thereof if fully paid:

                  FIRST:  To the payment of costs and expenses of collection and
                  of all amounts payable to the Trustee under Section 7.06; and

                  SECOND: To the payment of the amounts then due and unpaid upon
                  Debentures of such series for principal (and premium,  if any)
                  and interest,  in respect of which or for the benefit of which
                  such money has been collected,  ratably, without preference or
                  priority of any kind, according to the amounts due and payable
                  on such  Debentures  for principal  (and premium,  if any) and
                  interest, respectively.

         SECTION 6.04.  Limitation on Suits by Holders of Debentures.  No holder
of any  Debenture of any series shall have any right by virtue or by availing of
any provision of this  Indenture to institute any suit,  action or proceeding in
equity  or at law upon or under or with  respect  to this  Indenture  or for the
appointment of a receiver or trustee, or for any other remedy hereunder,  unless
such  holder  previously  shall have given to the Trustee  written  notice of an
Event of Default and of the  continuance  thereof with respect to  Debentures of
such series  specifying  such Event of Default,  as hereinbefore  provided,  and
unless also the holders of not less than 25% in  aggregate  principal  amount of
the Debentures of such series then  outstanding  shall have made written request
upon the Trustee to institute such action, suit or proceeding in its own name as
trustee  hereunder  and  shall  have  offered  to the  Trustee  such  reasonable
indemnity as it may require  against the costs,  expenses and  liabilities to be
incurred  therein or  thereby,  and the Trustee for 60 days after its receipt of
such notice, request and offer of indemnity,  shall have failed to institute any
such action,  suit or proceeding;  it being  understood and intended,  and being
expressly  covenanted by the taker and holder of every  Debenture of such series
with every other such taker and holder and Trustee,  that no one or more holders
of  Debentures  of such series shall have any right in any manner  whatsoever by
virtue or by availing of any provision of this  Indenture to affect,  disturb or
prejudice  the  rights of the  holders  of any other of such  Debentures,  or to
obtain or seek to obtain  priority  over or preference to any other such holder,
or to enforce  any right  under  this  Indenture,  except in the  manner  herein
provided  and for the  equal,  ratable  and  common  benefit  of all  holders of
Debentures of such series.  For the protection and enforcement of the provisions
of this  Section,  each  and  every  Debentureholder  and the  Trustee  shall be
entitled to such relief as can be given either at law or in equity.






                                       33



         Notwithstanding  any other provisions of this Indenture,  however,  the
right of any holder of any Debenture to receive payment of the principal of (and
premium,  if any) and interest on such  Debenture,  as therein  provided,  on or
after the  respective  due dates  expressed in such Debenture (or in the case of
redemption, on the redemption date), or to institute suit for the enforcement of
any such payment on or after such respective dates or redemption date, shall not
be impaired or affected without the consent of such holder.

         SECTION  6.05.  Remedies  Cumulative;  Delay or Omission in Exercise of
Rights Not Waiver of Default.  (a) All powers and remedies given by this Article
to the Trustee or to the Debentureholders shall, to the extent permitted by law,
be deemed  cumulative  and not  exclusive of any others  thereof or of any other
powers and remedies  available to the Trustee or the holders of the  debentures,
by judicial  proceedings or otherwise,  to enforce  performance or observance of
the  covenants  and   agreements   contained  in  this  Indenture  or  otherwise
established with respect to such Debentures.

         (b) No delay or  omission of the Trustee or of any holder of any of the
Debentures  to exercise  any right or power  accruing  upon any Event of Default
occurring and continuing as aforesaid  shall impair any such right or power,  or
shall  be  construed  to be a  waiver  of any such  default  or an  acquiescence
therein;  and, subject to the provisions of Section 6.04, every power and remedy
given by this Article or by law to the Trustee or to the Debentureholders may be
exercised from time to time, and as often as shall be deemed  expedient,  by the
Trustee or by the Debentureholders.

         SECTION  6.06.  Rights of Holders of  Majority in  Principal  Amount of
Debentures to Direct Trustee and to Waive Defaults. The holders of a majority in
aggregate  principal  amount  of the  Debentures  of  any  series  at  the  time
outstanding,  determined in accordance  with Section 8.04 (with,  in the case of
any series of Debentures held as trust assets of a AES Trust and with respect to
which a Security Exchange has not theretofore occurred,  such consent of holders
of the Preferred  Securities and the Common  Securities of such AES Trust as may
be required under the  Declaration  of Trust of such AES Trust),  shall have the
right to 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 with respect to such series; provided,  however, that such direction
shall not be in conflict  with any rule of law or with this  Indenture or unduly
prejudicial  to the rights of holders of  Debentures  of any other series at the
time outstanding determined in accordance with Section 8.04 not parties thereto.
Subject to the  provisions of Section 7.01,  the Trustee shall have the right to
decline to follow any such  direction if the Trustee in good faith  shall,  by a
Responsible Officer or Officers of the Trustee, determine that the proceeding so
directed  would  involve  the Trustee in  personal  liability.  The holders of a
majority in aggregate  principal  amount of the  Debentures of any series at the
time outstanding  affected  thereby,  determined in accordance with section 8.04
(with,  in the case of any series of  Debentures  held as trust  assets of a AES
Trust  and  with  respect  to  which a  Security  Exchange  has not  theretofore
occurred, such consent of holders of the Preferred



                                       34



Securities and the Common  Securities of such AES Trust as may be required under
the Declaration of Trust of such AES Trust), may on behalf of the holders of all
of the  Debentures of such series waive any past default in the  performance  of
any of the covenants  contained  herein or established  pursuant to section 2.01
with  respect  to such  series  and its  consequences,  except a default  in the
payment of the  principal  of, or premium,  if any,  or interest  on, any of the
Debentures  of that series as and when the same shall become due by the terms of
such  Debentures  otherwise than by  acceleration  (unless such default has been
cured and a sum  sufficient  to pay all matured  installments  of  interest  and
principal  and any premium has been  deposited  with the Trustee (in  accordance
with Section  6.01(c)) or a call for  redemption  of  Debentures of that series.
Upon any such waiver,  the default  covered  thereby shall be deemed to be cured
for all purposes of this Indenture and the Company,  the Trustee and the holders
of the Debentures of such series shall be restored to their former positions and
rights  hereunder,  respectively;  but  no  such  waiver  shall  extend  to  any
subsequent or other default or impair any right consequent thereon.

         SECTION 6.07.  Trustee to Give Notice of Defaults  Known To It, But May
Withhold in Certain  Circumstances.  The Trustee shall, within 90 days after the
occurrence of a default with respect to a particular  series,  transmit by mail,
first class postage  prepaid,  to the holders of  Debentures of that series,  as
their names and  addresses  appear upon the  Debenture  Register,  notice of all
defaults with respect to that series known to the Trustee,  unless such defaults
shall have been cured before the giving of such notice (the term  "defaults" for
the purposes of this Section being hereby defined to be the events  specified in
subsections  (1),  (2), (3), (4) and (5) of Section  6.01(a),  not including any
periods of grace provided for therein and  irrespective  of the giving of notice
provided for by subsection (3) of Section  6.01(a));  provided,  that, except in
the case of default in the payment of the  principal of (or premium,  if any) or
interest  on any of the  Debentures  of that  series  or in the  payment  of any
sinking fund installment  established  with respect to that series,  the Trustee
shall be  protected  in  withholding  such notice if and so long as the board of
directors,  the executive  committee,  or a trust committee of directors  and/or
Responsible   Officers,  of  the  Trustee  in  good  faith  determine  that  the
withholding  of such notice is in the  interests of the holders of Debentures of
that series;  provided further, that in the case of any default of the character
specified in Section  6.01(a)(3)  with respect to  Debentures  of such series no
such notice to the holders of the Debentures of that series shall be given until
at least 30 days after the occurrence thereof.

         The  Trustee  shall  not be deemed to have  knowledge  of any  default,
except (i) a default under  subsection  (a)(1) or (a)(2) of Section 6.01 as long
as the Trustee is acting as paying agent for such series of  Debentures  or (ii)
any  default as to which the Trustee  shall have  received  written  notice or a
Responsible Officer charged with the administration of this Indenture shall have
obtained written notice.





                                       35



         SECTION 6.08.  Requirements  of an  Undertaking to Pay Costs in Certain
Suits Under Indenture or Against  Trustee.  All parties to this Indenture agree,
and each holder of any  Debentures  by his or her  acceptance  thereof  shall be
deemed to have agreed, that any court may in its discretion require, in any suit
for the enforcement of any right or remedy under this Indenture,  or in any suit
against the Trustee for any action taken or omitted by it as Trustee, the filing
by any party  litigant in such suit of an  undertaking  to pay the costs of such
suit,  and that  such  court  may in its  discretion  assess  reasonable  costs,
including  reasonable  attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by
such party  litigant;  but the provisions of this Section shall not apply to any
suit instituted by the Trustee,  to any suit instituted by any  Debentureholder,
or group of  Debentureholders,  holding  more  than 10% in  aggregate  principal
amount of the outstanding Debentures of any series, or to any suit instituted by
any  Debentureholder  for the enforcement of the payment of the principal of (or
premium,  if any) or interest on any  Debenture of such series,  on or after the
respective due dates expressed in such Debenture or established pursuant to this
Indenture.


                                    ARTICLE 7
                             CONCERNING THE TRUSTEE

         SECTION 7.01. Upon Event of Default  Occurring and Continuing,  Trustee
Shall  Exercise  Powers  Vested In It, and Use Same  Degree of Care and Skill In
Their Exercise,  as Prudent Individual Would Use. (a) The Trustee,  prior to the
occurrence  of an Event of Default  with respect to  Debentures  of a series and
after the curing of all Events of Default  with  respect to  Debentures  of that
series  which may have  occurred,  shall  undertake  to perform  with respect to
Debentures  of such series such duties and only such duties as are  specifically
set forth in this  Indenture,  and no implied  covenants shall be read into this
Indenture  against  the  Trustee.  In case an Event of Default  with  respect to
Debentures  of a series has occurred  (which has not been cured or waived),  the
Trustee  shall  exercise  with respect to  Debentures of that series 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 man would exercise or use under
the circumstances in the conduct of his own affairs.

         (b) No  provision of this  Indenture  shall be construed to relieve the
Trustee from liability for its own negligent  action,  its own negligent failure
to act, or its own willful misconduct, except that:

               (1) prior to the  occurrence  of an Event of Default with respect
               to  Debentures of a series and after the curing or waiving of all
               such Events of Default with respect to that series which may have
               occurred:



                                       36



                           (i) the duties and  obligations  of the Trustee shall
                           with  respect  to   Debentures   of  such  series  be
                           determined  solely by the express  provisions of this
                           Indenture,  and the Trustee  shall not be liable with
                           respect to  Debentures  of such series except for the
                           performance  of such  duties and  obligations  as are
                           specifically  set  forth  in this  Indenture,  and no
                           implied  covenants or obligations  shall be read into
                           this Indenture against the Trustee; and

                           (ii) in the  absence  of bad faith on the part of the
                           Trustee,  the Trustee may with respect to  Debentures
                           of such series  conclusively rely, as to the truth of
                           the  statements  and the  correctness of the opinions
                           expressed therein,  upon any certificates or opinions
                           furnished  to  the  Trustee  and  conforming  to  the
                           requirements  of this  Indenture;  but in the case of
                           any  such  certificates  or  opinions  which  by  any
                           provision  hereof  are  specifically  required  to be
                           furnished to the Trustee,  the Trustee shall be under
                           a duty to examine  the same to  determine  whether or
                           not  they  conform  to  the   requirements   of  this
                           Indenture  but need not  confirm or  investigate  the
                           accuracy of mathematical  calculations or other facts
                           stated therein;

                  (2) the Trustee  shall not be liable for any error of judgment
                  made in good faith by a  Responsible  Officer  or  Responsible
                  Officers  of the  Trustee,  unless it shall be proved that the
                  Trustee was negligent in ascertaining the pertinent facts;

                  (3) the Trustee shall not be liable with respect to any action
                  taken or omitted to be taken by it in good faith in accordance
                  with the  direction of the holders of not less than a majority
                  in  principal  amount of the  Debentures  of any series at the
                  time  outstanding  relating  to the time,  method and place of
                  conducting  any  proceeding  for any remedy  available  to the
                  Trustee,  or exercising any trust or power  conferred upon the
                  Trustee under this Indenture with respect to the Debentures of
                  that series; and

                  (4) none of the provisions  contained in this Indenture  shall
                  require  the  Trustee  to  expend  or risk  its own  funds  or
                  otherwise   incur   personal   financial   liability   in  the
                  performance  of any of its duties or in the exercise of any of
                  its  rights  or  powers,  if there is  reasonable  ground  for
                  believing




                                       37



                  that  the   repayment  of  such  funds  or  liability  is  not
                  reasonably  assured to it under the terms of this Indenture or
                  adequate indemnity against such risk is not reasonably assured
                  to it.

                  (5)  Whether  or not  therein  expressly  so  provided,  every
                  provision  of  this  Indenture  relating  to  the  conduct  or
                  affecting  the  liability  of or affording  protection  to the
                  Trustee shall be subject to the provisions of this Article 7.

         SECTION  7.02.  Subject  to  Provisions  of  Section  7.01.  Except  as
otherwise provided in Section 7.01:

                           (a) The  Trustee may rely and shall be  protected  in
                  acting  or  refraining   from  acting  upon  any   resolution,
                  certificate,  statement,  instrument, opinion, report, notice,
                  request,  consent,  order,  approval,  bond, security or other
                  paper or  document  believed  by it to the genuine and to have
                  been signed or presented by the proper party or parties;

                           (b) Any  request,  direction,  order or demand of the
                  Company mentioned herein shall be sufficiently  evidenced by a
                  Board  Resolution or an  instrument  signed in the name of the
                  Company  by the  President  or any Vice  President  and by the
                  Secretary  or an Assistant  Secretary  or the  Treasurer or an
                  Assistant  Treasurer (unless other evidence in respect thereof
                  is specifically prescribed herein);

                           (c) The  Trustee  may  consult  with  counsel  of its
                  selection  and  the  written  advice  of such  counsel  or any
                  Opinion of Counsel  shall be full and  complete  authorization
                  and  protection  in respect of any action taken or suffered or
                  omitted hereunder in good faith and in reliance thereon;

                           (d) The  Trustee  shall  be under  no  obligation  to
                  exercise  any of the  rights  or  powers  vested in it by this
                  Indenture  at the  request,  order or  direction of any of the
                  Debentureholders,   pursuant   to  the   provisions   of  this
                  Indenture,  unless such Debentureholders shall have offered to
                  the  Trustee  reasonable  security  or  indemnity  against the
                  costs,  expenses and liabilities which may be incurred therein
                  or thereby;  nothing herein contained shall, however,  relieve
                  the Trustee of the obligation, upon the occurrence of an Event
                  of Default with respect to a series of the  Debentures  (which
                  has not been  cured or  waived) to  exercise  with  respect to
                  Debentures of that series such of the rights and powers vested
                  in it by this  Indenture,  and to use the same  degree of care
                  and skill in their  exercise,  as a prudent man would exercise
                  or use  under  the  circumstances  in the  conduct  of his own
                  affairs;



                                       38



                           (e) The  Trustee  shall not be liable  for any action
                  taken or omitted to be taken by it in good faith and  believed
                  by it to be authorized  or within the  discretion or rights or
                  powers conferred upon it by this Indenture;

                           (f) 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,  consent,  order,  approval,  bond,
                  security,  or other papers or documents,  unless  requested in
                  writing so to do by the holders of not less than a majority in
                  principal   amount  of  the  outstanding   Debentures  of  the
                  particular series affected thereby  (determined as provided in
                  Section 8.04); provided, however, that if the payment within a
                  reasonable  time to the  Trustee  of the  costs,  expenses  or
                  liabilities  likely to be incurred by it in the making of such
                  investigation   is,  in  the  opinion  of  the  Trustee,   not
                  reasonably  assured to the Trustee by the security afforded to
                  it by the terms of this  Indenture,  the  Trustee  may require
                  reasonable   indemnity   against   such  costs,   expenses  or
                  liabilities  as a condition to so  proceeding.  The reasonable
                  expense of every such examination shall be paid by the Company
                  or, if paid by the  Trustee,  shall be  repaid by the  Company
                  upon demand; and

                           (g) The  Trustee  may  execute  any of the  trusts or
                  powers  hereunder  or  perform  any  duties  hereunder  either
                  directly or by or through  agents or attorneys and the Trustee
                  shall not be  responsible  for any misconduct or negligence on
                  the part of any agent or attorney  appointed  with due care by
                  it hereunder.

         SECTION  7.03.  Trustee  Not Liable for  Recitals  In  Indenture  Or In
Debentures.  (a) The recitals contained herein and in the Debentures (other than
the  Certificate  of  Authentication  on the  Debentures)  shall be taken as the
statements of the Company,  and the Trustee  assumes no  responsibility  for the
correctness of the same.

         (b)  The  Trustee  makes  no  representations  as to  the  validity  or
sufficiency of this Indenture or of the Debentures.

         (c) The Trustee shall not be accountable  for the use or application by
the Company of any of the Debentures or of the proceeds of such  Debentures,  or
for the use or  application of any moneys paid over by the Trustee in accordance
with any provision of this Indenture or established pursuant to Section 2.01, or
for the use or application of any moneys received by any paying agent other than
the Trustee.

         SECTION  7.04.  Trustee,  Paying Agent or Debenture  Registrar  May Own
Debentures.  The  Trustee or any paying  agent or  Debenture  Registrar,  in its
individual or




                                       39


any other capacity,  may become the owner or pledgee of Debentures with the same
rights  it  would  have  if it were  not  Trustee,  paying  agent  or  Debenture
Registrar.

         SECTION  7.05.  Moneys  Received by Trustee to Be Held In Trust Without
Interest. Subject to the provisions of Section 11.04, all moneys received by the
Trustee shall,  until used or applied as herein  provided,  be held in trust for
the purposes for which they were received, but need not be segregated from other
funds  except to the  extent  required  by law.  The  Trustee  shall be under no
liability for interest on any moneys received by it hereunder  except such as it
may agree with the Company to pay thereon.

         SECTION  7.06.  Trustee  Entitled to  Compensation,  Reimbursement  and
Indemnity.  (a) The Company covenants and agrees to pay to the Trustee from time
to time, and the Trustee shall be entitled to, such  reasonable  compensation as
the  Company  and the  Trustee  shall from time to time agree in writing  (which
shall not be limited by any provision of law in regard to the  compensation of a
trustee of an express trust) for all services rendered by it in the execution of
the trusts  hereby  created and in the  exercise and  performance  of any of the
powers  and  duties  hereunder  of the  Trustee,  and the  Company  will  pay or
reimburse   the  Trustee   upon  its  request  for  all   reasonable   expenses,
disbursements  and advances  incurred or made by the Trustee in accordance  with
any of the provisions of this Indenture  (including the reasonable  compensation
and the  expenses  and  disbursements  of its  counsel  and of all  persons  not
regularly in its employ) except any such expense, disbursement or advance as may
arise from its negligence or bad faith.  The Company also covenants to indemnify
the Trustee (and its officers, agents, directors and employees) for, and to hold
it harmless against,  any loss, liability or expense including taxes (other than
taxes  based  upon,  measured  by or  determined  by the income of the  Trustee)
incurred without  negligence or bad faith on the part of the Trustee and arising
out of or in connection  with the  acceptance or  administration  of this trust,
including  the costs and  expenses  of  defending  itself  against  any claim of
liability in the premises.

         (b) The obligations of the Company under this Section to compensate and
indemnify  the  Trustee  and to pay  or  reimburse  the  Trustee  for  expenses,
disbursements and advances shall constitute additional  indebtedness  hereunder.
Such  additional  indebtedness  shall be  secured by a lien prior to that of the
Debentures upon all property and funds held or collected by the Trustee as such,
except  funds  held in  trust  for the  benefit  of the  holders  of  particular
Debentures.

         SECTION 7.07.  Right of Trustee to Rely on  Certificate  of Officers of
Company Where No Other  Evidence  Specifically  Prescribed.  Except as otherwise
provided in Section 7.01,  whenever in the  administration  of the provisions of
this Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or  established  prior to taking or  suffering  or  omitting  to take any
action  hereunder,  such matter  (unless  other  evidence in respect  thereof be
herein  specifically  prescribed) may, in the absence of negligence or bad faith
on the part of the Trustee,  be deemed to be conclusively proved




                                       40


and  established by an Officers'  Certificate  delivered to the Trustee and such
certificate,  in the  absence  of  negligence  or bad  faith  on the part of the
Trustee,  shall be full warrant to the Trustee for any action taken, suffered or
omitted to be taken by it under the  provisions of this Indenture upon the faith
thereof.

         SECTION  7.08.  Trustee  Acquiring  Conflicting  Interest to  Eliminate
Conflict  or Resign.  (a) If the Trustee  has or shall  acquire any  conflicting
interest,  as defined in this  Section,  with respect to the  Debentures  of any
series and if the  Default to which such  conflicting  interest  relates has not
been  cured,  duly  waived  or  otherwise  eliminated,   within  90  days  after
ascertaining  that it has such conflicting  interest,  it shall either eliminate
such conflicting  interest,  except as otherwise provided herein, or resign with
respect  to the  Debentures  of that  series in the  manner  and with the effect
specified in Section  7.10 and the Company  shall  promptly  appoint a successor
Trustee in the manner provided herein.

         (b) In the  event  that  the  Trustee  shall  fail to  comply  with the
provisions of subsection (a) of this Section,  with respect to the Debentures of
any series the  Trustee  shall,  within  ten days after the  expiration  of such
90-day  period,  transmit  notice of such failure by mail,  first class  postage
prepaid,  to the  Debentureholders  of that series as their names and  addresses
appear upon the registration books.

         (c) For the  purposes of this  Section  the Trustee  shall be deemed to
have a conflicting  interest  with respect to the  Debentures of any series if a
Default has occurred and is continuing and:

                  (1) the Trustee is trustee under this  Indenture  with respect
                  to the  outstanding  Debentures  of any series other than that
                  series,  or is trustee under another indenture under which any
                  other securities, or certificates of interest or participation
                  in any  other  securities,  of the  Company  are  outstanding,
                  unless such other  indenture is a collateral  trust  indenture
                  under which the only collateral  consists of Debentures issued
                  under this  Indenture;  provided  that there shall be excluded
                  from the  operation of this  paragraph  the  Debentures of any
                  series  other  than that  series  and any other  indenture  or
                  indentures  under which other  securities,  or certificates of
                  interest or participation in other securities,  of the Company
                  are outstanding if (i) this Indenture and such other indenture
                  or indentures and all series of securities issuable thereunder
                  are wholly unsecured and rank equally and such other indenture
                  or indentures (and such series) are hereafter  qualified under
                  the Trust  Indenture  Act,  unless the  Commission  shall have
                  found and  declared  by order  pursuant to  subsection  (b) of
                  Section  305 or  subsection  (c) of  Section  307 of the Trust
                  Indenture  Act,  that   differences   exist  between  (A)  the
                  provisions  of this  Indenture  with respect to  Debentures of
                  that series and with respect to one or more other series or



                                       41



                  (B) the  provisions of this  Indenture  and the  provisions of
                  such other indenture or indentures (or such series), which are
                  so likely to involve a material  conflict  of  interest  as to
                  make it necessary in the public interest or for the protection
                  of  investors  to  disqualify  the Trustee from acting as such
                  under this  Indenture  with respect to the  Debentures of that
                  series  and such  other  series  or such  other  indenture  or
                  indentures,  or (ii) the  Company  shall  have  sustained  the
                  burden of proving,  on application to the Commission and after
                  opportunity for hearing  thereon,  that the trusteeship  under
                  this  Indenture  with respect to Debentures of that series and
                  such other series or such other indenture or indentures is not
                  so likely to involve a material  conflict  of  interest  as to
                  make it necessary in the public interest or for the protection
                  of  investors  to  disqualify  the Trustee from acting as such
                  under this Indenture with respect to Debentures of that series
                  and such other series or under such other indentures;

                  (2) the Trustee or any of its directors or executive  officers
                  is an underwriter for the Company;

                  (3) the Trustee directly or indirectly controls or is directly
                  or  indirectly  controlled  by or is under  direct or indirect
                  common control with or an underwriter for the Company;

                  (4) the Trustee or any of its directors or executive  officers
                  is  a  director,  officer,  partner,  employee,  appointee  or
                  representative  of the Company,  or of an  underwriter  (other
                  than the Trustee  itself)  for the  Company  who is  currently
                  engaged in the business of  underwriting,  except that (A) one
                  individual  may be a director  and/or an executive  officer of
                  the Trustee and a director and/or an executive  officer of the
                  Company,  but may not be at the same time an executive officer
                  of both the Trustee and the Company; (B) if and so long as the
                  number  of  directors  of the  Trustee  in office is more than
                  nine,  one additional  individual may be a director  and/or an
                  executive  officer  of  the  Trustee  and a  director  of  the
                  Company;  and (C) the Trustee may be designated by the Company
                  or by an underwriter for the Company to act in the capacity of
                  transfer agent,  registrar,  custodian,  paying agent,  fiscal
                  agent,  escrow agent,  or depository,  or in any other similar
                  capacity,  or,  subject to the  provisions of paragraph (1) of
                  this  subsection  (c),  to act as  trustee  whether  under  an
                  indenture or otherwise;

                  (5) 10% or more of the  voting  securities  of the  Trustee is
                  beneficially  owned either by the Company or by any  director,
                  partner,  or executive officer thereof, or 20% or more of such

                  collateral  security for an obligation which is in default (as
                  hereinafter in this subsection (c) defined), (A) 5% or more of
                  the voting  securities,  or 10% or more of any other  class of
                  security,  of the Company, not including the Debentures issued
                  under this  Indenture  and  securities  issued under any other
                  indenture under which the Trustee is also trustee,  or (B) 10%
                  or more of any class of  security  of an  underwriter  for the
                  Company;

                  (7) the  Trustee  is the  beneficial  owner  of,  or  holds as
                  collateral  security for an obligation which is in default (as
                  hereinafter in this subsection (c) defined), 5% or more of the
                  voting  securities  of any person who, to the knowledge of the
                  Trustee,  owns 10% or more of the  voting  securities  of,  or
                  controls directly or indirectly or is under direct or indirect
                  common control with, the Company;

                  (8) the  Trustee  is the  beneficial  owner  of,  or  holds as
                  collateral  security for an obligation which is in default (as
                  hereinafter in this  subsection  (c) defined),  10% or more of
                  any class of security of any person who, to the  knowledge  of
                  the Trustee,  owns 50% or more of the voting securities of the
                  Company;

                  (9)  the  Trustee  owns,  on the  date  of  Default  upon  the
                  Debentures  of any series or any  anniversary  of such Default
                  while  such  Default  upon the  Debentures  issued  under this
                  Indenture  remains  outstanding,  in the capacity of executor,
                  administrator,  testamentary or inter vivos trustee, guardian,
                  committee or conservator, or in any other similar capacity, an
                  aggregate of 25% or more of the voting  securities,  or of any
                  class of security,  of any person, the beneficial ownership of
                  a  specified  percentage  of which  would have  constituted  a
                  conflict of interest under  paragraph (6), (7), or (8) of this
                  subsection (c). As to any such securities of which the Trustee
                  acquired ownership through becoming executor, administrator or
                  testamentary  trustee of an estate which  includes  them,  the
                  provisions of the preceding  sentence  shall not apply,  for a
                  period of two years from the date of such acquisition,  to the
                  extent that such  securities  in such estate do not exceed 25%
                  of  such  voting  securities  or  25%  of any  such  class  of
                  security.  Promptly  after the dates of any such  Default upon
                  the  Debentures  issued under this  Indenture  and annually in
                  each  succeeding  year that the  Debentures  issued under this
                  Indenture remain in Default, the Trustee shall make a check of
                  its holding of such  securities in any of the  above-






                                       43



                  mentioned capacities as of such dates. If the Company fails to
                  make payment in full of principal of or interest on any of the
                  Debentures  when and as the same becomes due and payable,  and
                  such failure  continues  for 30 days  thereafter,  the Trustee
                  shall make a prompt check of its holding of such securities in
                  any of the  above-mentioned  capacities  as of the date of the
                  expiration  of  such  30-day  period,  and  after  such  date,
                  notwithstanding  the foregoing  provisions  of this  paragraph
                  (9), all such securities so held by the Trustee,  with sole or
                  joint control over such  securities  vested in it, shall,  but
                  only so long as such failure shall continue,  be considered as
                  though  beneficially  owned by the Trustee for the purposes of
                  paragraphs (6), (7) and (8) of this subsection (c); or

                  (10) except  under the  circumstances  described  in paragraph
                  (1), (3),  (4), (5) or (6) of  subsection  (b) of Section 7.13
                  the  Trustee  shall  be or  shall  become  a  creditor  of the
                  Company.

         For purposes of paragraph  (1) of this  subsection  (c), and of Section
6.06, the term "series of securities" or "securities"  means a series,  class or
group of securities  issuable under an indenture pursuant to whose terms holders
of one such series may vote to direct the indenture  trustee,  or otherwise take
action  pursuant to a vote of such holders,  separately  from holders of another
such  series;  provided,  that,  "series of  securities"  or "series"  shall not
include any series of securities  issuable under an indenture if all such series
rank equally and are wholly secured.

         The  specification of percentages in paragraphs (5) to (9),  inclusive,
of this  subsection (c) shall not be construed as indicating  that the ownership
of  such  percentages  of  securities  of a  person  is or is not  necessary  or
sufficient  to  constitute  direct  or  indirect  control  for the  purposes  of
paragraph (3) or (7) of this subsection (c).

         For the purposes of paragraphs (6), (7), (8) and (9) of this subsection
(c) only,  (A) the terms  "security"  and  "securities"  shall include only such
securities as are generally known as corporate securities, but shall not include
any note or other evidence of  indebtedness  issued to evidence an obligation to
repay moneys lent to a person by one or more banks,  trust  companies or banking
firms,  or any  certificate  of  interest or  participation  in any such note or
evidence of indebtedness;  (B) an obligation shall be deemed to be in "default",
when a default in payment of principal  shall have continued for 30 days or more
and shall not have been cured; and (C) the Trustee shall not be deemed to be the
owner or holder of (i) any security  which it holds as  collateral  security (as
trustee or otherwise) for any  obligation  which is not in default as defined in
clause (B) above,  or (ii) any security  which it holds as  collateral  security
under  this  Indenture,  irrespective  of any  Default  hereunder,  or (iii) any
security which it holds as agent for collection,  or as custodian,  escrow agent
or depositary, or in any similar representative capacity.

                  the time as of which the  determination is made, has purchased

                  the  Company  in  connection  with,  the  distribution  of any
                  security  of the  Company,  or has  participated  or has had a
                  direct or indirect  participation in any such undertaking,  or
                  has  participated or has had a participation  in the direct or
                  indirect  underwriting of any such undertaking,  but such term

                  "trust"  shall  include  only a trust  where the  interest  or
                  interests of the beneficiary or beneficiaries are evidenced by
                  a security.

                  (4)  The  term  "voting  security"  shall  mean  any  security
                  presently entitling the owner or holder thereof to vote in the

                  (5) The  term  "Company"  shall  mean  any  obligor  upon  the

                                       45

                  (1) A specified  percentage  of the voting  securities  of the
                  Trustee,  the Company or any other person  referred to in this
                  Section  (each of whom is  referred  to as a "person"  in this
                  paragraph)  means  such  amount  of  the  outstanding   voting
                  securities  of such person as  entitles  the holder or holders
                  thereof to cast such  specified  percentage  of the  aggregate
                  votes  which  the  holders  of  all  the  outstanding   voting
                  securities  of  such  person  are  entitled  to  cast  in  the
                  direction or management of the affairs of such person.

                  (2) A  specified  percentage  of a class  of  securities  of a
                  person  means  such  percentage  of the  aggregate  amount  of
                  securities of the class outstanding.

                  (3) The term  "amount",  when used in  regard  to  securities,

                  (4) The term "outstanding" means issued and not held by or for
                  the account of the issuer. The following  securities shall not

                           relating  to  securities  of the  issuer  of the same
                           class;

                           (ii)  securities  of an issuer held in a sinking fund
                           relating  to  another  class  of  securities  of  the
                           issuer,  if the  obligation  evidenced  by such other
                           class of securities is not in default as to principal
                           or interest or otherwise;

                           (iii)  securities  pledged by the  issuer  thereof as
                           security  for  an  obligation  of the  issuer  not in

                                       46



                           (iv) securities held in escrow if placed in escrow by
                           the  issuer  thereof,  provided,  however,  that  any
                           voting  securities  of  an  issuer  shall  be  deemed
                           outstanding  if any  person  other than the issuer is
                           entitled to exercise the voting rights thereof.

                  (5) A  security  shall be  deemed  to be of the same  class as
                  another security if both securities  confer upon the holder or
                  holders thereof  substantially the same rights and privileges;
                  provided,  however,  that, in the case of secured evidences of
                  indebtedness,   all  of  which  are  issued   under  a  single
                  indenture, differences in the interest rates or maturity dates
                  of various  series  thereof shall not be deemed  sufficient to
                  constitute  such  series  different  classes;   and  provided,
                  further,   that,  in  the  case  of  unsecured   evidences  of
                  indebtedness,  differences  in the interest  rates or maturity
                  dates  thereof  shall not be deemed  sufficient  to constitute
                  them securities of different classes,  whether or not they are
                  issued under a single indenture.

         (f) Except in the case of a default in the payment of the  principal of
(or premium,  if any) or interest on any Debentures issued under this Indenture,
or in the  payment of any sinking or  analogous  fund  installment,  the Trustee
shall not be required to resign as provided by this Section 7.08 if such Trustee
shall have sustained the burden of proving, on application to the Commission and
after opportunity for hearing thereon,  that (i) the default under the Indenture
may be cured or waived  during a  reasonable  period  and  under the  procedures
described in such  application  and (ii) a stay of the Trustee's  duty to resign
will not be inconsistent with the interests of  Debentureholders.  The filing of
such an  application  shall  automatically  stay the  performance of the duty to
resign until the Commission orders otherwise.

         Any  resignation  of the Trustee shall become  effective  only upon the
appointment of a successor  trustee and such  successor's  acceptance of such an
appointment.

         SECTION 7.09.  Requirements for Eligibility of Trustee.  There shall at
all times be a Trustee with respect to the  Debentures  issued  hereunder  which
shall at all times be a corporation  organized and doing business under the laws
of the  United  States of America  or any State or  Territory  thereof or of the
District of  Columbia,  or a  corporation  or other  person  permitted to act as
trustee by the  Commission,  authorized  under such laws to  exercise  corporate
trust  powers,  having a  combined  capital  and  surplus of at least 50 million
dollars,   and  subject  to  supervision  or  examination  by  Federal,   State,
Territorial,  or District of Columbia authority.  If such corporation  publishes
reports of condition at least annually,  pursuant to law or to the  requirements
of the aforesaid  supervising or examining  authority,  then for the purposes of
this  Section,  the combined  capital and surplus of such  corporation  shall be
deemed to be its  combined  capital  and surplus as set forth in its most recent
report of  condition  so  published.  The  Company  may not,  nor may any person
directly or indirectly controlling,  controlled by, or under common control with
the





                                       47


Company,  serve as Trustee.  In case at any time the  Trustee  shall cease to be
eligible in accordance  with the  provisions of this Section,  the Trustee shall
resign immediately in the manner and with the effect specified in Section 7.10.

         SECTION 7.10. Resignation of Trustee and Appointment of Successor.  (a)
The Trustee or any successor  hereafter  appointed,  may at any time resign with
respect to the Debentures of one or more series by giving written notice thereof
to the Company and by  transmitting  notice of resignation by mail,  first class
postage  prepaid,  to the  Debentureholders  of such series,  as their names and
addresses  appear upon the Debenture  Register.  Upon  receiving  such notice of
resignation, the Company shall promptly appoint a successor trustee with respect
to Debentures of such series by written  instrument,  in duplicate,  executed by
order of the Board of Directors, one copy of which instrument shall be delivered
to the resigning Trustee and one copy to the successor trustee.  If no successor
trustee  shall have been so appointed and have  accepted  appointment  within 30
days after the mailing of such notice of resignation,  the resigning Trustee may
petition any court of competent  jurisdiction for the appointment of a successor
trustee with respect to Debentures  of such series,  or any  Debentureholder  of
that series who has been a bona fide holder of a Debenture or Debentures  for at
least six months may,  subject to the  provisions  of Section 6.08, on behalf of
himself  and all  others  similarly  situated,  petition  any such court for the
appointment of a successor trustee.  Such court may thereupon after such notice,
if any, as it may deem proper and prescribe, appoint a successor trustee.

         (b) In case at any time any of the following shall occur:

                  (1) the Trustee  shall fail to comply with the  provisions  of
                  subsection (a) of Section 7.08 after written request  therefor
                  by the Company or by any  Debentureholder  who has been a bona
                  fide  holder of a  Debenture  or  Debentures  for at least six
                  months; or

                  (2) the Trustee shall cease to be eligible in accordance  with
                  the  provisions of Section 7.09 and shall fail to resign after
                  written  request  therefor  by  the  Company  or by  any  such
                  Debentureholder; or

                  (3) the Trustee shall become incapable of acting,  or shall be
                  adjudged  bankrupt or insolvent,  or a receiver of the Trustee
                  or of its property  shall be appointed,  or any public officer
                  shall take charge or control of the Trustee or of its property
                  or affairs for the purpose of rehabilitation,  conservation or
                  liquidation,

then,  in any such case,  the Company may remove the Trustee with respect to all
Debentures and appoint a successor trustee by written instrument,  in duplicate,
executed by order of the Board of Directors,  one copy of which instrument shall
be delivered to the Trustee so removed and one copy to the successor trustee. If
no successor trustee shall




                                       48


have been so appointed  and have accepted  appointment  within 30 days after the
mailing of such notice of removal, the Trustee so removed may petition any court
of  competent  jurisdiction  for the  appointment  of a successor  trustee  with
respect to Debentures of such series, or any  Debentureholder of that series who
has been a bona fide holder of a Debenture or Debentures for at least six months
may,  subject to the  provisions  of Section  6.08, on behalf of himself and all
others  similarly  situated,  petition  any such  court for the  removal  of the
Trustee and the  appointment  of a successor  trustee.  Such court may thereupon
after such  notice,  if any,  as it may deem  proper and  prescribe,  remove the
Trustee and appoint a successor trustee.

         (c) The  holders of a majority  in  aggregate  principal  amount of the
Debentures  of any  series at the time  outstanding  may at any time  remove the
Trustee with respect to such series and appoint a successor trustee.

         (d) Any  resignation  or removal of the  Trustee and  appointment  of a
successor  trustee with respect to the Debentures of a series pursuant to any of
the  provisions  of this  Section  shall become  effective  upon  acceptance  of
appointment by the successor trustee as provided in Section 7.11.

         (e) Any  successor  trustee  appointed  pursuant to this Section may be
appointed  with respect to the  Debentures  of one or more series or all of such
series,  and at any time there  shall be only one  Trustee  with  respect to the
Debentures of any particular series.

         SECTION 7.11.  Acceptance  by Successor to Trustee.  (a) In case of the
appointment  hereunder of a successor  trustee  with respect to all  Debentures,
every such successor trustee so appointed shall execute, acknowledge and deliver
to  the  Company  and to the  retiring  Trustee  an  instrument  accepting  such
appointment,  and thereupon the  resignation or removal of the retiring  Trustee
shall become effective and such successor trustee, without any further act, deed
or  conveyance,  shall  become  vested with all the rights,  powers,  trusts and
duties of the  retiring  Trustee;  but,  on the  request  of the  Company or the
successor  trustee,  such retiring  Trustee shall,  upon payment of its charges,
execute and deliver an instrument transferring to such successor trustee all the
rights,  powers,  and trusts of the  retiring  Trustee  and shall  duly  assign,
transfer  and deliver to such  successor  trustee all property and money held by
such retiring Trustee hereunder.

         (b) In case of the  appointment  hereunder of a successor  trustee with
respect to the Debentures of one or more (but not all) series, the Company,  the
retiring  Trustee and each  successor  trustee with respect to the Debentures of
one or more series shall  execute and deliver an indenture  supplemental  hereto
wherein each successor trustee shall accept such appointment and which shall (1)
contain  such  provisions  as shall be  necessary  or  desirable to transfer and
confirm to, and to vest in,  each  successor  trustee  all the  rights,  powers,
trusts and duties of the retiring Trustee with respect to the Debentures of that
or those series to which the appointment of such successor trustee relates,  (2)
contain such





                                       49



provisions  as shall be deemed  necessary  or  desirable to confirm that all the
rights,  powers,  trusts and duties of the retiring  Trustee with respect to the
Debentures  of that or those  series as to which  the  retiring  Trustee  is not
retiring shall continue to be vested in the retiring Trustee,  and (3) add to or
change any of the  provisions of this Indenture as shall be necessary to provide
for or facilitate the  administration  of the trusts  hereunder by more than one
Trustee,  it  being  understood  that  nothing  herein  or in such  supplemental
indenture  shall  constitute such Trustees  co-trustees of the same trust,  that
each such Trustee shall be trustee of a trust or trusts  hereunder  separate and
apart from any trust or trusts hereunder  administered by any other such Trustee
and that no Trustee  shall be  responsible  for any act or failure to act on the
part of any other Trustee hereunder; and upon the execution and delivery of such
supplemental  indenture the resignation or removal of the retiring Trustee shall
become  effective to the extent provided  therein,  such retiring  Trustee shall
with respect to the Debentures of that or those series to which the  appointment
of such  successor  trustee  relates  have  no  further  responsibility  for the
exercise  of  rights  and  powers  or for  the  performance  of the  duties  and
obligations vested in the Trustee under this Indenture,  and each such successor
trustee,  without any further act, deed or conveyance,  shall become vested with
all the rights,  powers,  trusts and duties of the retiring Trustee with respect
to the  Debentures  of that or those  series  to which the  appointment  of such
successor  trustee  relates;  but,  on request of the  Company or any  successor
Trustee,  such retiring Trustee shall duly assign,  transfer and deliver to such
successor trustee,  to the extent  contemplated by such supplemental  indenture,
the property and money held by such retiring  Trustee  hereunder with respect to
the  Debentures  of that or  those  series  to  which  the  appointment  of such
successor trustee relates.

         (c) Upon  request of any such  successor  trustee,  the  Company  shall
execute  any and all  instruments  for more fully and  certainly  vesting in and
confirming to such successor trustee all such rights,  power and trusts referred
to in paragraph (a) or (b) of this Section, as the case may be.

         (d) No successor  trustee  shall accept its  appointment  unless at the
time of such acceptance  such successor  trustee shall be qualified and eligible
under this Article.

         (e) Upon  acceptance of appointment by a successor  trustee as provided
in this Section,  the Company shall  transmit  notice of the  succession of such
trustee hereunder by mail, first class postage prepaid, to the Debentureholders,
as their names and addresses appear upon the Debenture Register.  If the Company
fails to transmit such notice within ten days after acceptance of appointment by
the  successor  trustee,  the  successor  trustee  shall cause such notice to be
transmitted at the expense of the Company.

         SECTION  7.12.  Successor  to  Trustee  by  Merger,   Consolidation  or
Succession to Business.  Any corporation into which the Trustee may be merged or
converted or with which it may be  consolidated,  or any  corporation  resulting
from any merger, conversion



                                       50



or  consolidation  to which the  Trustee  shall be a party,  or any  corporation
succeeding to substantially  all of the corporate trust business of the Trustee,
shall be the successor of the Trustee hereunder, provided such corporation shall
be  qualified  under the  provisions  of  Section  7.08 and  eligible  under the
provisions of Section 7.09,  without the execution or filing of any paper or any
further act on the part of any of the  parties  hereto,  anything  herein to the
contrary notwithstanding.  In case any Debentures shall have been authenticated,
but not  made  available  for  delivery,  by the  Trustee  then in  office,  any
successor by merger,  conversion or consolidation to such authenticating Trustee
may adopt such  authentication and make available for delivery the Debentures so
authenticated  with the same  effect as if such  successor  Trustee  had  itself
authenticated such Debentures.

         SECTION 7.13.  Limitations on Rights of Trustee as a Creditor to Obtain
Payment of Certain Claims Within Four Months Prior to Default or During Default,
or to  Realize on  Property  as such  Creditor  Thereafter.  (a)  Subject to the
provisions of subsection  (b) of this Section,  if the Trustee shall be or shall
become a creditor, directly or indirectly,  secured or unsecured, of the Company
within  three months prior to a default,  as defined in  subsection  (b) of this
Section,  or subsequent to such a default,  then,  unless and until such default
shall be cured,  the Trustee  shall set apart and hold in a special  account for
the benefit of the Trustee  individually,  the holders of the Debentures and the
holders of other  indenture  securities  (as defined in  subsection  (c) of this
Section):

                  (1) an amount  equal to any and all  reductions  in the amount
                  due and owing  upon any claim as such  creditor  in respect of
                  principal or interest,  effected  after the  beginning of such
                  three months'  period and valid as against the Company and its
                  other creditors,  except any such reduction resulting from the
                  receipt or disposition of any property  described in paragraph
                  (2) of this  subsection,  or from the exercise of any right of
                  set-off which the Trustee  could have  exercised if a petition
                  in  bankruptcy  had been filed by or against the Company  upon
                  the date of such default; and

                  (2) all  property  received  by the  Trustee in respect of any
                  claim as such  creditor,  either as security  therefor,  or in
                  satisfaction or composition  thereof, or otherwise,  after the
                  beginning of such three months' period,  or an amount equal to
                  the proceeds of any such  property,  if disposed of,  subject,
                  however,  to the rights,  if any, of the Company and its other
                  creditors in such property or such proceeds.

         Nothing  herein  contained,  however,  shall  affect  the  right of the
Trustee:

                  (A) to retain for its own account (i) payments made on account
                  of any such claim by any person  (other than the  Company) who
                  is liable thereon, and (ii) the proceeds of the bona fide sale
                  of any such claim by the Trustee





                                       51



                  to a third  person,  and  (iii)  distributions  made in  cash,
                  securities,  or other  property  in  respect  of claims  filed
                  against the Company in bankruptcy or receivership or in a case
                  for reorganization  pursuant to the Federal Bankruptcy Code or
                  applicable State law;

                  (B) to realize, for its own account, upon any property held by
                  it as security  for any such claim,  if such  property  was so
                  held prior to the beginning of such three months' period;

                  (C) to realize, for its own account, but only to the extent of
                  the claim hereinafter mentioned,  upon any property held by it
                  as  security  for any such  claim,  if such claim was  created
                  after the  beginning  of such  three  months'  period and such
                  property was received as security therefor simultaneously with
                  the creation  thereof,  and if the Trustee  shall  sustain the
                  burden  of  proving  that at the  time  such  property  was so
                  received the Trustee had no reasonable cause to believe that a
                  default,  as defined in subsection (c) of this Section,  would
                  occur within three months; or

                  (D) to receive  payment on any claim  referred to in paragraph
                  (B) or  (C),  against  the  release  of any  property  held as
                  security for such claim as provided in such  paragraph  (B) or
                  (C),  as the case may be, to the  extent of the fair  value of
                  such property.

         For the purposes of paragraphs (B), (C) and (D),  property  substituted
after the beginning of such three  months'  period for property held as security
at the time of such  substitution  shall, to the extent of the fair value of the
property released,  have the same status as the property  released,  and, to the
extent  that any claim  referred  to in any of such  paragraphs  is  created  in
renewal of or in  substitution  for or for the purpose of repaying or  refunding
any  pre-existing  claim of the Trustee as such creditor,  such claim shall have
the same status as such pre-existing claim.

         If the Trustee  shall be required  to account,  the funds and  property
held in such  special  account and the  proceeds  thereof  shall be  apportioned
between the Trustee,  the  Debentureholders  and the holders of other  indenture
securities in such manner that the Trustee, the Debentureholders and the holders
of other indenture securities realize, as a result of payments from such special
account  and  payments  of  dividends  on claims  filed  against  the Company in
bankruptcy  or  receivership  or in a case for  reorganization  pursuant  to the




                                       52



Federal  Bankruptcy  Code or applicable  State law, the same percentage of their
respective claims, figured before crediting to the claim of the Trustee anything
on account of the  receipt by it from the  Company of the funds and  property in
such  special  account  and before  crediting  to the  respective  claims of the
Trustee,  the  Debentureholders  and the holders of other  indenture  securities
dividends on claims filed against the Company in bankruptcy or  receivership  or
in a  case  for  reorganization  pursuant  to the  Federal  Bankruptcy  Code  or
applicable  State law, but after  crediting  thereon  receipts on account of the
indebtedness  represented by their respective claims from all sources other than
from such  dividends  and from the funds and  property  so held in such  special
account.  As used  in this  paragraph,  with  respect  to any  claim,  the  term
"dividends"  shall  include any  distribution  with  respect to such  claim,  in
bankruptcy  or  receivership  or in a case for  reorganization  pursuant  to the
Federal  Bankruptcy Code or applicable State law,  whether such  distribution is
made in cash,  securities,  or other  property,  but shall not  include any such
distribution  with respect to the secured  portion,  if any, of such claim.  The
court in which such  bankruptcy,  receivership or a case for  reorganization  is
pending  shall have  jurisdiction  (i) to  apportion  between the  Trustee,  the
Debentureholders  and the holders of other indenture  securities,  in accordance
with the  provisions  of this  paragraph,  the funds and  property  held in such
special account and the proceeds thereof, or (ii) in lieu of such apportionment,
in  whole  or in  part,  to  give  to  the  provisions  of  this  paragraph  due
consideration in determining the fairness of the distributions to be made to the
Trustee, the Debentureholders and the holders of other indenture securities with
respect to their respective  claims, in which event it shall not be necessary to
liquidate or to appraise the value of any  securities or other  property held in
such special  account or as security  for any such claim,  or to make a specific
allocation of such  distributions as between the secured and unsecured  portions
of such  claims,  or otherwise to apply the  provisions  of this  paragraph as a
mathematical formula.

         Any Trustee who has  resigned or been  removed  after the  beginning of
such three months' period shall be subject to the provisions of this  subsection
(a) as though such  resignation or removal had not occurred.  If any Trustee has
resigned or been removed prior to the beginning of such three months' period, it
shall be subject to the  provisions  of this  subsection  (a) if and only if the
following conditions exist:

                  (i) the receipt of property or  reduction of claim which would
                  have given rise to the obligation to account,  if such Trustee
                  had continued as trustee, occurred after the beginning of such
                  three months' period; and

                  (ii) such receipt of property or  reduction of claim  occurred
                  within three months after such resignation or removal.

         (b) There shall be excluded  from the  operation of  subsection  (a) of
this Section a creditor relationship arising from:

                  (1) the ownership or  acquisition  of securities  issued under
                  any indenture, or any security or securities having a maturity
                  of one year or more at the time of acquisition by the Trustee;

                  (2) advances  authorized by a receivership or bankruptcy court
                  of  competent  jurisdiction,  or by  this  Indenture,  for the
                  purpose of preserving




                                       53



                  any  property  other  than  cash  which  shall  at any time be
                  subject  to  the  lien,  if  any,  of  this  Indenture  or  of
                  discharging  tax liens or other  prior  liens or  encumbrances
                  thereon,  if notice of such  advance and of the  circumstances
                  surrounding    the   making    thereof   is   given   to   the
                  Debentureholders  at the time and in the  manner  provided  in
                  this Indenture;

                  (3)  disbursements  made in the ordinary course of business in
                  the capacity of trustee  under an indenture,  transfer  agent,
                  registrar, custodian, paying agent, subscription agent, fiscal
                  agent or depositary, or other similar capacity;

                  (4) an indebtedness  created as a result of services  rendered
                  or premises rented; or an indebtedness  created as a result of
                  goods or securities  sold in a cash  transaction as defined in
                  subsection (c) of this Section;

                  (5) the ownership of stock or of other securities of a Company
                  organized under the provisions of Section 25(a) of the Federal
                  Reserve  Act, as amended,  which is directly or  indirectly  a
                  creditor of the Company; or

                  (6) the acquisition,  ownership,  acceptance or negotiation of
                  any drafts, bills of exchange, acceptance or obligations which
                  fall within the  classification of  self-liquidating  paper as
                  defined in subsection (c) of this Section.

         (c) As used in this Section:

                  (1) The term "default"  shall mean any failure to make payment
                  in full of the  principal of (or premium,  if any) or interest
                  upon  any  of  the  Debenture  or  upon  the  other  indenture
                  securities when and as such principal (or premium,  if any) or
                  interest becomes due and payable.

                  (2) Th e  term  "other   indenture   securities"   shall  mean
                  securities upon which the Company is an obligor (as defined in
                  the Trust Indenture Act) outstanding under any other indenture
                  (A)  under  which  the  Trustee  is also  trustee,  (B)  which
                  contains provisions substantially similar to the provisions of
                  subsection (a) of this Section,  and (C) under which a default
                  exists  at the  time of the  apportionment  of the  funds  and
                  property held in said special account.

                  (3) The term "cash  transaction" shall mean any transaction in

                                    ARTICLE 8
                            CONCERNING THE DEBENTURES

         SECTION 8.01. Evidence of Action by Debentureholders.  Whenever in this
Indenture it is provided that the holders of a majority or specified  percentage
in aggregate  principal amount of the Debentures of a particular series may take
any action  (including  the making of any demand or  request,  the giving of any
notice,  consent or waiver or the taking of any other  action)  the fact that at
the time of taking any such  action the holders of such  majority  or  specified
percentage of that series have joined therein may be evidenced by any instrument
or any  number of  instruments  of similar  tenor  executed  by such  holders of
Debentures of that series in person or by agent or proxy appointed in writing.

         If the Company  shall solicit from the  Debentureholders  of any series
any request, demand, authorization,  direction, notice, consent, waiver or other
action,   the  Company  may,  at  its  option,  as  evidenced  by  an  Officers'
Certificate,  fix in advance a record date for such series for the determination
of  Debentureholders  entitled  to give  such  request,  demand,  authorization,
direction,  notice,  consent, waiver or other action, but the Company shall have
no  obligation to do so. If such a record date is fixed,  such request,  demand,
authorization,  direction,  notice, consent, waiver or other action may be given
before or after the record date, but only the  Debentureholders of record at the
close of business on the record date shall be deemed to be Debentureholders  for
the purposes of determining whether Debentureholders of the requisite proportion
of outstanding  Debentures of that series have authorized or agreed or consented
to such request, demand,  authorization,  direction,  notice, consent, waiver or
other  action,  and for that purpose the  outstanding  Debentures of that series
shall be computed as of the record date; provided




                                       55



that no such authorization, agreement or consent by such Debentureholders on the
record date shall be deemed effective unless it shall become effective  pursuant
to the  provisions of this  Indenture not later than six months after the record
date.

         SECTION  8.02.  Proof of  Execution  of  Instruments  and of Holding of
Debentures. Subject to the provisions of Section 7.01, proof of the execution of
any instrument by a Debentureholder  (such proof will not require  notarization)
or his  agent or proxy  and  proof of the  holding  by any  person of any of the
Debentures shall be sufficient if made in the following manner;

                  (a) The fact and date of the  execution  by any such person of
                  any  instrument  may  be  proved  in  any  reasonable   manner
                  acceptable to the Trustee.

                  (b)  The  ownership  of  Debentures  shall  be  proved  by the
                  Debenture  Register of such  Debentures or by a certificate of
                  the Debenture Registrar thereof.

                  (c) The  Trustee  may  require  such  additional  proof of any
                  matter referred to in this Section as it shall deem necessary.

         SECTION 8.03. Who May Be Deemed Owners of Debentures.  Prior to the due
presentment  for  registration  of transfer of any Debenture,  the Company,  the
Trustee,  any paying agent and any  Debenture  Registrar  may deem and treat the
person in whose name such  Debenture  shall be registered  upon the books of the
Company as the absolute owner of such  Debenture  (whether or not such Debenture
shall be overdue and  notwithstanding any notice of ownership or writing thereon
made by anyone other than the Debenture  Registrar) for the purpose of receiving
payment of or on account of the principal of,  premium,  if any, and (subject to
Section 2.03) interest on such Debenture and for all other purposes; and neither
the Company nor the Trustee  nor any paying  agent nor any  Debenture  Registrar
shall be affected by any notice to the contrary.

         SECTION  8.04.   Debentures   Owned  by  a  Company  or  Controlled  or
Controlling  Companies  Disregarded for Certain Purposes. In determining whether
the holders of the  requisite  aggregate  principal  amount of  Debentures  of a
particular series have concurred in any direction,  consent or waiver under this
Indenture, Debentures of that series which are owned by the Company or any other
obligor on the  Debentures of that series or by any Subsidiary of the Company or
of such other obligor on the Debentures of that series shall be disregarded  and
deemed not to be outstanding for the purpose of any such  determination,  except
that for the purpose of  determining  whether the Trustee  shall be protected in
relying on any such direction, consent or waiver, only Debentures of such series
which  the  Trustee  actually  knows  are  so  owned  shall  be so  disregarded.
Debentures  so owned  which have been  pledged in good faith may be  regarded as




                                       56



outstanding for the purposes of this Section,  if the pledgee shall establish to
the  satisfaction  of the Trustee the pledgee's  right so to act with respect to
such  Debentures  and that the pledgee is not a person  directly  or  indirectly
controlling or controlled by or under direct or indirect common control with the
Company or any such other  obligor.  In case of a dispute as to such right,  any
decision  by the  Trustee  taken  upon  the  advice  of  counsel  shall  be full
protection to the Trustee.

         SECTION  8.05.  Instruments  Executed by  Debentureholders  Bind Future
Holders.  At any time prior to (but not after) the evidencing to the Trustee, as
provided  in Section  8.01,  of the  taking of any action by the  holders of the
majority or  percentage  in aggregate  principal  amount of the  Debentures of a
particular  series  specified in this Indenture in connection  with such action,
any holder of a Debenture  of that series  which is shown by the  evidence to be
included in the  Debentures  the holders of which have  consented to such action
may, by filing  written  notice with the  Trustee,  and upon proof of holding as
provided in Section 8.02,  revoke such action so far as concerns such Debenture.
Except as aforesaid any such action taken by the holder of any  Debenture  shall
be  conclusive  and  binding  upon such  holder and upon all future  holders and
owners of such Debenture,  and of any Debenture issued in exchange therefor,  on
registration of transfer thereof or in place thereof, irrespective of whether or
not any notation in regard thereto is made upon such Debenture. Any action taken
by the holders of the majority or  percentage in aggregate  principal  amount of
the Debentures of a particular  series specified in this Indenture in connection
with such action shall be conclusively binding upon the Company, the Trustee and
the holders of all the Debentures of that series.

                             SUPPLEMENTAL INDENTURES

         SECTION 9.01. Purposes for Which Supplemental  Indenture May Be Entered
Into  Without  Consent of  Debentureholders.  In  addition  to any  supplemental
indenture otherwise authorized by this Indenture,  the Company,  when authorized
by a Board  Resolution,  and the  Trustee  may from time to time and at any time
enter into an indenture or indentures  supplemental  hereto (which shall conform
to the  provisions of the Trust  Indenture  Act as then in effect),  without the
consent of the Debentureholders, for one or more of the following purposes:

                  (a) to evidence the  succession of another  corporation to the
                  Company,  and the  assumption  by any  such  successor  of the
                  covenants  of  the  Company   contained  herein  or  otherwise
                  established with respect to the Debentures; or



                                       57


                  (b) to  add to the  covenants  of  the  Company  such  further
                  covenants,  restrictions,  conditions  or  provisions  for the
                  protection  of the  holders  of the  Debentures  of all or any
                  series  as the  Board  of  Directors  and  the  Trustee  shall
                  consider to be for the protection of the holders of Debentures
                  of all or any  series,  and to  make  the  occurrence,  or the
                  occurrence  and  continuance,  of a  default  in any  of  such
                  additional covenants, restrictions, conditions or provisions a
                  default or an Event of  Default  with  respect to such  series
                  permitting  the  enforcement  of all  or  any  of the  several
                  remedies  provided  in this  Indenture  as herein  set  forth;
                  provided,  however,  that in  respect  of any such  additional
                  covenant,    restriction,    condition   or   provision   such
                  supplemental  indenture may provide for a particular period of
                  grace  after  default  (which  period may be shorter or longer
                  than  that  allowed  in the  case of  other  defaults)  or may
                  provide for an immediate  enforcement upon such default or may
                  limit the remedies  available to the Trustee upon such default
                  or may  limit  the  right  of the  holders  of a  majority  in
                  aggregate principal amount of the Debentures of such series to
                  waive such default; or

                  (c) to cure any  ambiguity  or to  correct or  supplement  any
                  provision  contained herein or in any  supplemental  indenture
                  which  may  be  defective  or  inconsistent   with  any  other
                  provision  contained herein or in any supplemental  indenture,
                  or to make such  other  provisions  in regard  to  matters  or
                  questions  arising  under  this  Indenture  as  shall  not  be
                  inconsistent  with the  provisions of this Indenture and shall
                  not  adversely  affect  the  interests  of the  holders of the
                  Debentures of any series; or

                  (d) to  change  or  eliminate  any of the  provisions  of this
                  Indenture,  provided that any such change or elimination shall
                  become  effective only when there is no Debenture  outstanding
                  of  any  series   created  prior  to  the  execution  of  such
                  supplemental  indenture  which is  entitled  to the benefit of
                  such provision.

         The  Trustee  is  hereby  authorized  to join with the  Company  in the
execution  of  any  such  supplemental  indenture,   and  to  make  any  further
appropriate agreements and stipulations which may be therein contained,  but the
Trustee  shall not be  obligated to enter into any such  supplemental  indenture
which  affects  the  Trustee's  own  rights,  duties or  immunities  under  this
Indenture or otherwise.

         Any supplemental indenture authorized by the provisions of this Section
may be  executed  by the  Company  and the  Trustee  without  the consent of the
holders of any of the Debentures at the time outstanding, notwithstanding any of
the provisions of Section 9.02.



                                       58


         SECTION   9.02.    Modification    of   Indenture   with   Consent   of
Debentureholders.  With the consent  (evidenced  as provided in Section 8.01) of
the holders of not less than a majority  in  aggregate  principal  amount of the
Debentures of each series affected by such supplemental  indenture or indentures
at the time  outstanding  (and, in the case of any series of Debentures  held as
trust assets of an AES Trust and with  respect to which a Security  Exchange has
not theretofore  occurred,  such consent of holders of the Preferred  Securities
and the  Common  Securities  of such AES  Trust  as may be  required  under  the
Declaration of Trust of such AES Trust), the Company, when authorized by a Board
Resolution,  and the Trustee may from time to time and at any time enter into an
indenture  or  indentures  supplemental  hereto  (which  shall  conform  to  the
provisions  of the Trust  Indenture  Act as then in effect)  for the  purpose of
adding any  provisions  to or changing in any manner or  eliminating  any of the
provisions of this Indenture or of any supplemental indenture or of modifying in
any manner the rights of the holders of the Debentures of such series under this
Indenture;  provided,  however,  that no such  supplemental  indenture shall (i)
extend  the fixed  maturity  of any  Debentures  of any  series,  or reduce  the
principal  amount  thereof,  or reduce the rate or extend the time of payment of
interest  thereon,  or reduce any premium  payable upon the redemption  thereof,
without the consent of the holder of each  Debenture  so affected or (ii) reduce
the  aforesaid  percentage of  Debentures,  the holders of which are required to
consent to any such supplemental  indenture,  without the consent of the holders
of each  Debenture  (and, in the case of any series of Debentures  held as trust
assets of an AES Trust and with  respect  to which a Security  Exchange  has not
theretofore  occurred,  such consent of the holders of the Preferred  Securities
and the  Common  Securities  of such AES  Trust  as may be  required  under  the
Declaration of Trust of such AES Trust) then outstanding and affected thereby.

         Upon the  request of the  Company,  accompanied  by a Board  Resolution
authorizing  the  execution  of any such  supplemental  indenture,  and upon the
filing with the Trustee of evidence of the consent of Debentureholders  (and, in
the case of any series of  Debentures  held as trust  assets of an AES Trust and
with respect to which a Security  Exchange has not  theretofore  occurred,  such
consent of holders of the Preferred Securities and the Common Securities of such
AES Trust as may be required  under the  Declaration of Trust of such AES Trust)
required  to  consent  thereto as  aforesaid,  the  Trustee  shall join with the
Company in the execution of such supplemental indenture unless such supplemental
indenture  affects the  Trustee's own rights,  duties or  immunities  under this
Indenture  or  otherwise,  in which case the Trustee may in its  discretion  but
shall not be obligated to enter into such supplemental indenture.

         It shall not be necessary  for the consent of the  Debentureholders  of
any series affected thereby under this Section to approve the particular form of
any proposed supplemental indenture,  but it shall be sufficient if such consent
shall approve the substance thereof.






                                       59


         Promptly  after the  execution  by the  Company  and the Trustee of any
supplemental  indenture pursuant to the provisions of this Section,  the Trustee
shall transmit by mail, first class postage prepaid, a notice,  setting forth in
general   terms  the   substance  of  such   supplemental   indenture,   to  the
Debentureholders  of all series  affected  thereby as their names and  addresses
appear  upon the  Debenture  Register.  Any  failure of the Trustee to mail such
notice, or any defect therein,  shall not, however,  in any way impair or affect
the validity of any such supplemental indenture.

         SECTION 9.03. Effect of Supplemental Indentures.  Upon the execution of
any  supplemental  indenture  pursuant to the  provisions  of this Article or of
Section 10.01,  this  Indenture  shall,  with respect to such series,  be and be
deemed to be modified and amended in  accordance  therewith  and the  respective
rights,  limitations of rights,  obligations,  duties and immunities  under this
Indenture  of the  Trustee,  the Company and the  holders of  Debentures  of the
series affected thereby shall  thereafter be determined,  exercised and enforced
hereunder subject in all respects to such modifications and amendments,  and all
the terms and  conditions  of any such  supplemental  indenture  shall be and be
deemed to be part of the terms and  conditions of this Indenture for any and all
purposes.

         SECTION 9.04.  Debentures May Bear Notation of Changes By  Supplemental
Indentures.  Debentures  of any series,  affected by a  supplemental  indenture,
authenticated and delivered after the execution of such  supplemental  indenture
pursuant  to the  provisions  of this  Article or of Section  10.01,  may bear a
notation  in  form  approved  by the  Company,  provided  such  form  meets  the
requirements  of any  exchange  upon which such series may be listed,  as to any
matter  provided for in such  supplemental  indenture.  If the Company  shall so
determine,  new  Debentures  of that series so  modified  as to conform,  in the
opinion  of the  Board  of  Directors,  to any  modification  of this  Indenture
contained  in any such  supplemental  indenture  may be prepared by the Company,
authenticated  by the Trustee and  delivered in exchange for the  Debentures  of
that series then outstanding.

         SECTION  9.05.  Opinion  of  Counsel.  The  Trustee,   subject  to  the
provisions  of Section  7.01,  may  receive an Opinion of Counsel as  conclusive
evidence that any supplemental  indenture  executed  pursuant to this Article is
authorized  or permitted by, and conforms to, the terms of this Article and that
it is proper for the Trustee under the provisions of this Article to join in the
execution thereof.

shall not  consolidate  with or merge into any other Person or transfer or lease
its properties and assets  substantially  as an entirety to any Person,  and the
Company shall not permit any other Person to consolidate  with or merge into the
Company, unless:

                           (a)  either  the  Company  shall  be  the  continuing
                  corporation,  or the  corporation  (if other than the Company)
                  formed by such  consolidation  or into  which the  Company  is
                  merged or to which the  properties  and assets of the  Company
                  substantially  as an entity are transferred or leased shall be
                  a  corporation  organized  and existing  under the laws of the
                  United  States of America or any State thereof or the District
                  of  Columbia  and  shall  expressly  assume,  by an  indenture
                  supplemental hereto, executed and delivered to the Trustee, in
                  form  satisfactory to the Trustee,  all the obligations of the
                  Company under the Debentures and this Indenture; and

                           (b)   immediately   after   giving   effect  to  such
                  transaction  no Event of Default,  and no event  which,  after
                  notice  or  lapse of time or both,  would  become  an Event of
                  Default, shall have occurred and be continuing.

         SECTION  10.02.  Successor  Corporation   Substituted.   The  successor
corporation  formed by such consolidation or into which the Company is merged or
to which such transfer or lease is made shall succeed to and be substituted for,
and may exercise every right and power of, the Company under this Indenture with
the same effect as if such successor  corporation  had been named as the Company
herein,  and  thereafter  (except in the case of a lease to another  Person) the
predecessor corporation shall be relieved of all obligations and covenants under
the  Indenture  and the  Debentures  and,  in the  event of such  conveyance  or
transfer, any such predecessor corporation may be dissolved and liquidated.

         SECTION  10.03.  Opinion  of  Counsel.  The  Trustee,  subject  to  the
provisions  of Section  7.01,  may  receive an Opinion of Counsel as  conclusive
evidence that any such  consolidation,  merger,  sale,  conveyance,  transfer or
other disposition,  and any such assumption,  comply with the provisions of this
Article.

            SATISFACTION AND DISCHARGE OF INDENTURE; UNCLAIMED MONEYS

         SECTION 11.01. Satisfaction and Discharge of Indentures.  (A) If at any
time (a) the Company  shall have paid or caused to be paid the  principal of and
interest on all the Debentures of any series  Outstanding  hereunder (other than
Debentures  of such series which have been  destroyed,  lost or stolen and which
have been  replaced or paid as  provided  in Section  2.07) as and when the same
shall have become due and payable,  or (b) the Company  shall have  delivered to
the  Trustee  for  cancellation   all  Debentures  of  any  series   theretofore
authenticated  (other than any  Debentures  of such series which shall have been

in  Section  2.07)  or (c) (i) all the  Debentures  of  series  not  theretofore

proper  instruments  acknowledging  such  satisfaction of and  discharging  this
Indenture;  provided,  that the rights of Holders of the  Debentures  to receive

policies of any securities  exchange upon which the  Debentures are listed.  The
Company agrees to




                                       62


reimburse  the  Trustee  for any costs or  expenses  thereafter  reasonably  and

Indenture or the Debentures of such series.

         (B) The  following  provisions  shall apply to the  Debentures  of each
series unless specifically otherwise provided in a Board Resolution or indenture

the  obligations  of the Company  under  Section  4.02) and the Trustee,  at the
expense  of  the  Company,  shall  at  the  Company's  request,  execute  proper
instruments acknowledging the same, if

                  (a)  with   reference  to  this   provision  the  Company  has
                  irrevocably  deposited or caused to be  irrevocably  deposited
                  with the Trustee as trust funds in trust, specifically pledged
                  as security for, and  dedicated  solely to, the benefit of the
                  holders  of the  Debentures  of  such  series  (i)  cash in an
                  amount,  or  (ii)  Governmental  Obligations  maturing  as  to
                  principal  and  interest at such times and in such  amounts as
                  will insure the  availability  of cash 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 (A) the
                  principal  and  interest on all  Debentures  of such series on
                  each date that such  principal  or interest is due and payable
                  or  is  earlier  redeemed   (irrevocably  provided  for  under
                  arrangements satisfactory to the Trustee), as the case may be,
                  and (B) any  mandatory  sinking fund  payments on the dates on
                  which such payments are due and payable in accordance with the
                  terms of the Indenture and the Debentures of such series;

                  (b) such deposit will not result in a breach or violation  of,
                  or constitute a default under,  any agreement or instrument to
                  which the Company is a party or by which it is bound;



                                       63


                  (c) the  Company  has  delivered  to the Trustee an Opinion of
                  Counsel  based on the fact that (x) the Company  has  received
                  from,  or there has been  published  by, the Internal  Revenue
                  Service a ruling or (y) since the date hereof,  there has been
                  a change in the  applicable  Federal income tax law, in either
                  case to the effect that,  and such opinion shall confirm that,
                  the  holders  of  the  Debentures  of  such  series  will  not
                  recognize income, gain or loss for Federal income tax purposes
                  as a result of such deposit, defeasance and discharge 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

                  provisions  of  Section  14.02 or  14.03,  would  prevent  the
                  Company from making  payments of the  principal of or interest
                  on the Debentures of such series on the date of such deposit.

Debentures  of such  series for the payment or  redemption  of which such moneys

Trustee  and  thereupon  such paying  agent  shall be released  from all further
liability with respect to such moneys.

         SECTION  11.04.  Repayment of Moneys Held by Paying  Agent.  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  of any series and not  applied but

interest shall have become due and payable,  shall,  upon the written request of
the Company and unless otherwise required by



                                       64


mandatory  provisions of applicable  escheat or abandoned or unclaimed  property
law,  be repaid to the  Company by the  Trustee  for such  series or such paying
agent,  and the Holder of the Debentures of such series 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;  provided,
however,  that the Trustee or such paying agent,  before being  required to make
any such  repayment  with  respect to moneys  deposited  with it for any payment
series, shall at the expense of the Company, mail by first-class mail to holders

         SECTION 13.10.  Separability of Indenture Provisions.  .In case any one
or more of the  provisions  contained in this  Indenture or in the Debentures of
any series shall for any reason be held to be invalid,  illegal or unenforceable
in any respect, such invalidity, illegality or unenforceability shall not affect
any other provisions of this Indenture or of such Debentures, but this Indenture
and  such  Debentures  shall be  construed  as if such  invalid  or  illegal  or
unenforceable provision had never been contained herein or therein.

         SECTION 13.11.  Assignment by Company to  Subsidiary.  The Company will
have the right at all times to assign  any of its  rights or  obligations  under

Beneficiaries  of the Indenture;  Holders of Preferred  Securities May Institute
Legal  Proceedings  Against the  Company in Certain  Cases.  The Company  hereby
acknowledges  that,  to the extent  specifically  set forth  herein,  prior to a
Security  Exchange  with respect to the  Debentures  of any series held as trust
assets of a AES Trust, the holders of the Preferred Securities of such AES Trust
shall  expressly be third party  beneficiaries  of this  Indenture.  The Company
further  acknowledges  that,  prior  to a  Security  Exchange  with  respect  to
Debentures  of any series held as trust  assets of a AES Trust,  if the Property
Trustee of such AES Trust fails to enforce its rights  under this  Indenture  as
the holder of the Debentures of a series held as trust assets of such AES Trust,
any holder of the Preferred  Securities  of such AES Trust may  institute  legal
proceedings  directly  against the Company to enforce  such  Property  Trustee's
rights under this  Indenture  without first  instituting  any legal  proceedings
against such Property  Trustee or any other person or entity;  provided that, if
an Event of Default has occurred and is continuing  and such event is attributed
to the failure of the Company to pay interest or principal on the  Debentures on
the date such  interest or  principal  is  otherwise  payable (or in the case of
redemption,  on the redemption date),  then a holder of Preferred  Securities of
such AES Trust may directly institute a proceeding for enforcement of payment to
such holder of the principal of or interest on the Debentures having a principal
amount equal to the aggregate  liquidation amount of the Preferred Securities of
such  holder (a "Holder  Direct  Action")  on or after the  respective  due date
specified in the Debentures.  In connection with such Holder Direct Action,  the
rights  of the  holders  of the  Common  Securities  of such AES  Trust  will be
subrogated to the rights of such holder of Preferred Securities to the extent of
any payment made by the Company to such holders of Preferred  Securities in such
Holder Direct Action. Except as provided in the preceding sentences, the holders
of Preferred  Securities of such AES Trust will not be able to exercise directly
any other  remedy  available  to the holders of the  Debentures.  Reference to a
"holder" of Preferred




                                       68


Securities or Common  Securities herein shall mean a "Holder" of such securities
as defined in the Declaration of Trust.


                                   ARTICLE 14
                           SUBORDINATION OF DEBENTURES

         SECTION  14.01.  Agreement to  Subordinate.  The Company  covenants and
agrees,  and each  Debentureholder  issued  hereunder by his acceptance  thereof
likewise  covenants and agrees,  that all Debentures  shall be issued subject to
the provisions of this Article;  and each person holding any Debenture,  whether
upon original issue or upon transfer, assignment or exchange thereof accepts and
agrees that the  Principal of and interest on all  Debentures  issued  hereunder
shall,  to the extent and in the manner herein set forth,  be  subordinated  and
subject in right to the prior  payment  in full of all  Senior and  Subordinated
Debt.

         SECTION 14.02. Payments to Debentureholders.  No payments on account of
principal of, premium, if any, or interest on the Debentures 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 and Subordinated 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 and
Subordinated  Debt  pursuant to which the maturity  thereof may be  accelerated,
from and after the date of receipt by the  Trustee  of written  notice  from the
holders of such Designated Senior and Subordinated Debt or from an agent of such
holders,  no payments on account of principal,  premium,  if any, or interest in
respect of the  Debentures  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 and
Subordinated Debt or from an agent of such holders, or such event of default has
been cured or waived or has ceased to exist).  Only one Payment  Blockage Period
may be  commenced  with  respect  to the  Debentures  during  any  period of 360
consecutive  days. No event of default  which  existed or was  continuing on the
date of the  commencement  of any Payment  Blockage  Period with  respect to the
Designated  Senior and Subordinated Debt initiating such Payment Blockage Period
shall be or be made the basis for the  commencement  of any  subsequent  Payment
Blockage Period by the holders of such Designated Senior and Subordinated  Debt,
unless such event of default shall have been cured or waived for a period of not
less than 90 consecutive days.

         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,




                                       69



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 and  Subordinated  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,  premium,  if
any, or interest on the indebtedness  evidenced by the Debentures,  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  Debentureholders  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  Debentureholders  or by the
Trustee under this Indenture if received by them or it,  directly to the holders
of Senior and  Subordinated  Debt (pro rata to such  holders on the basis of the
respective  amounts of Senior and  Subordinated  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 and
Subordinated  Debt may have  been  issued,  as their  respective  interests  may
appear,  to the extent necessary to pay all Senior and Subordinated 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 and Subordinated  Debt,  before any payment or distribution is
made to the holders of the  indebtedness  evidenced by the  Debentures 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 by the  foregoing,  shall be received by the
Trustee under this Indenture or the holders of the Debentures  before all Senior
and  Subordinated  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 and  Subordinated  Debt or their  respective  representatives,  or to the
trustee  or  trustees  under any  indenture  pursuant  to which any  instruments
evidencing  any of such Senior and  Subordinated  Debt may have been issued,  as
their  respective  interests may appear,  for  application to the payment of all
Senior  and  Subordinated  Debt  remaining  unpaid  until  all such  Senior  and
Subordinated  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 and Subordinated 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




                                       70


extent  provided in this Article with respect to the  Debentures) to the payment
of all  Senior  and  Subordinated  Debt  which  may at the time be  outstanding;
provided,  that (i) the  Senior  and  Subordinated  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 and Subordinated
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 10 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 10. Nothing
in this Section  shall apply to claims of, or payments to, the Trustee  under or
pursuant to Article 7, except as provided therein. This Section shall be subject
to the further provisions of Section 14.05.

         SECTION 14.03.  Subrogation  of  Debentures.  Subject to the payment in
full of all Senior and Subordinated Debt, the holders of the Debentures shall be
subrogated  to the  rights of the  holders of Senior  and  Subordinated  Debt to
receive payments or distributions of cash, property or securities of the Company
applicable  to the  Senior and  Subordinated  Debt  until the  principal  of and
interest on the Debentures  shall be paid in full; and, for the purposes of such
subrogation,  no  payments  or  distributions  to the  holders of the Senior and
Subordinated  Debt of any cash,  property or  securities to which the holders of
the  Debentures 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 and  Subordinated  Debt by holders of the
Debentures  or the Trustee on their behalf  shall,  as between the Company,  its
creditors other than holders of Senior and Subordinated  Debt and the holders of
the Debentures, be deemed to be a payment by the Company to or on account of the
Senior and Subordinated Debt; and no payments or distributions of cash, property
or  securities  to or for the  benefit of the  Debentureholders  pursuant to the
subrogation  provision of this Article,  which would otherwise have been paid to
the holders of Senior and  Subordinated  Debt shall be deemed to be a payment by
the Company to or for the account of the  Debentures.  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 Debentures,  on the one hand,
and the holders of the Senior and Subordinated Debt, on the other hand.

          Nothing contained in this Article or elsewhere in this Indenture or in
the  Debentures  is intended to or shall  impair,  as between the  Company,  its
creditors  other  than the  holders  of Senior and  Subordinated  Debt,  and the
holders of the Debentures,  the obligation of the Company, which is absolute and
unconditional,  to pay to the holders of the  Debentures  the  principal  of and
interest on the  Debentures as and when the same shall become due and payable in
accordance with their terms, or is intended to or shall affect




                                       71


the  relative  rights of the  holders of the  Debentures  and  creditors  of the
Company other than the holders of the Senior and  Subordinated  Debt,  nor shall
anything herein or therein prevent the holder of any Debenture 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  and  Subordinated  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 Article 7, and the
holders of the  Debentures  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  trustee,  agent or other person making such payment or
distribution,  delivered to the Trustee or to the holders of the Debentures, for
the  purpose  of  ascertaining  the  persons  entitled  to  participate  in such
distribution,  the  holders  of the  Senior  and  Subordinated  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 14.04.  Authorization  by  Debentureholders.  Each holder of a
Debenture 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 14.05. 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 Debentures 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 and Subordinated  Debt or of any default or event of
default with respect to any Senior and  Subordinated  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 and Subordinated 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 and Subordinated Debt shall
be  outstanding,  and,  prior to the  receipt of any such  written  notice,  the
Trustee  shall,  subject to the  provisions  of Article 7, 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




                                       72


of the  principal of, or interest on any  Debenture)  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 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 Debentureholders of amounts
in connection  with a redemption of Debentures if (i) notice of such  redemption
has been  given  pursuant  to Article 3 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 Debentureholders of amounts deposited with it pursuant to Article
11.

          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 and
Subordinated Debt (or a trustee on behalf of such holder) to establish that such
notice has been given by a holder of Senior and  Subordinated  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 and  Subordinated  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 and  Subordinated  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 14.06. Trustee's Relation to Senior and Subordinated 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 and  Subordinated
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  and  Subordinated  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 Article 7.

          With  respect  to the  holders of Senior and  Subordinated  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 and Subordinated
Debt shall be read into this  Indenture  against the Trustee.  The Trustee shall
not be  deemed  to  owe  any  fiduciary  duty  to  the  holders  of  Senior  and
Subordinated Debt and, subject to the provisions of Article 7, the Trustee shall



                                       73


not be liable to any holder of Senior and Subordinated Debt if it shall pay over
or deliver to holders of  Debentures,  the Company or any other person moneys or
assets to which any holder of Senior and Subordinated  Debt shall be entitled by
virtue of this Article or otherwise.

          SECTION 14.07. No Impairment to Subordination. No right of any present
or future holder of any Senior and Subordinated 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.

         The First  National  Bank of Chicago,  as Trustee,  hereby  accepts the
trust in this  Indenture  declared and provided,  upon the terms and  conditions
herein above set forth.




                                       74


         IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be

attested, all as of the day and year first above written.
