and C hereto,  a waiver of an Indenture Event of Default by the Property Trustee
at the written direction of the Holders of the Preferred Securities  constitutes
a waiver of the corresponding Event of Default under this Declaration in respect

incidental  thereto.  The Trust shall not borrow  money,  issue debt or reinvest
proceeds derived from investments, pledge any of its assets or at any time while
the Securities are outstanding, otherwise undertake (or permit to be undertaken)
any  activity  that would result in or cause the Trust to be treated as anything
other than a grantor trust for United States federal income tax purposes.

         SECTION 3.06.  Authority.  Subject to the limitations  provided in this
Declaration  and to the  specific  duties of the Property  Trustee,  the Regular
Trustees shall have  exclusive and complete  authority to carry out the purposes
of the Trust.  An action taken by the Regular  Trustees in accordance with their
powers  shall  constitute  the act of and  serve to bind the Trust and an action
taken by the Property Trustee in accordance with its powers shall constitute the
act of and serve to bind the  Trust.  In  dealing  with the  Trustees  acting on
behalf of the Trust,  no Person shall be required to inquire into the  authority
of the Trustees to bind the Trust.  Persons  dealing with the Trust are entitled
to rely  conclusively on the power and authority of the Trustees as set forth in
this Declaration.

         SECTION  3.07.  Title to Property  of the Trust.  Except as provided in
Section 3.10 with respect to the Debentures  and the Property  Account or unless
otherwise  provided in this Declaration,  legal title to all assets of the Trust
shall be vested in the Trust. The Holders shall not have legal title to any part
of the assets of the Trust,  but shall have an individual  undivided  beneficial
interest in the assets of the Trust.

         SECTION 3.08.  Powers and Duties of the Regular  Trustees.  The Regular
Trustees shall have the exclusive power,  authority and duty to cause the Trust,

Common  Securities,  and, provided further,  that there shall be no interests in
the Trust other than the  Securities  and the  issuance of  Securities  shall be

for the benefit of the Trust and the Holders of the Preferred Securities and the
Common Securities;

         (d) to cause the Trust to enter into the  Purchase  Agreement  and such

314(a)(4) of the Trust  Indenture Act, which  certificate may be executed by any
Regular Trustee;

         (k) to incur expenses which are necessary or incidental to carrying out
any of the purposes of the Trust;

         (l) to act as,  or  appoint  another  Person to act as,  registrar  and
transfer  agent  for the  Securities,  the  Regular  Trustees  hereby  initially

         (m) to take all actions  and perform  such duties as may be required of

         (o) to take all action which may be necessary  or  appropriate  for the
preservation  and the  continuation  of the  Trust's  valid  existence,  rights,

State of Delaware  and of each other  jurisdiction  in which such  existence  is
necessary to protect the limited  liability of the Holders of the  Securities or
to enable the Trust to effect the purposes for which the Trust has been created;

         (p) to take all action,  not inconsistent with this Declaration or with
applicable law, which the Regular  Trustees  determine in their discretion to be
reasonable  and  necessary or desirable  in carrying out the  activities  of the
Trust as set out in this Section 3.08, in order that:

              (i) the  Trust  will not be  deemed  to be an  Investment  Company
         required to be registered under the Investment Company Act;

              (ii) the Trust will not be classified  for United  States  federal
         income tax purposes as an  association  taxable as a  corporation  or a
         partnership  and will be treated as a grantor  trust for United  States
         federal income tax purposes; and

              (iii) the Trust will comply with any  requirements  imposed by any
         taxing authority on holders of instruments  treated as indebtedness for
         United States federal income tax purposes;



                                       18



provided that such action does not adversely affect the interests of Holders;

         (q) to take all action  necessary to cause all  applicable  tax returns
and tax  information  reports  that are required to be filed with respect to the
Trust to be duly  prepared and filed by the Regular  Trustees,  on behalf of the
Trust; and

         (r)  subject  to the  requirements  of Rule 3a-7 and ss.  317(b) of the
Trust  Indenture  Act, to appoint  one or more Paying  Agents in addition to the
Property Trustee.

         The Regular Trustees must exercise the powers set forth in this Section
3.08 in a manner which is  consistent  with the  purposes  and  functions of the
Trust set out in Section 3.05 and the Regular Trustees shall not take any action
which is inconsistent  with the purposes and functions of the Trust set forth in
Section 3.05.

         Subject to this Section 3.08,  the Regular  Trustees shall have none of
the powers nor any of the authority of the Property Trustee set forth in Section
3.10.

         SECTION 3.09.  Prohibition of Actions by Trust and Trustees.  The Trust
shall not, and the Trustees  (including  the Property  Trustee)  shall cause the
Trust not to,  engage in any activity  other than as required or  authorized  by
this Declaration. In particular, the Trust shall not and the Trustees (including
the Property Trustee) shall not cause the Trust to:

         (a)  invest  any  proceeds  received  by the  Trust  from  holding  the
Debentures  but shall  promptly  distribute  all such  proceeds  to  Holders  of
Securities pursuant to the terms of this Declaration and of the Securities;

         (b) acquire any assets other than as expressly provided herein;

         (c) possess Trust property for other than a Trust purpose;

         (d) make any loans, other than loans represented by the Debentures;

         (e)  possess  any power or  otherwise  act in such a way as to vary the
Trust assets or the terms of the Securities in any way whatsoever;

         (f) issue any securities or other evidences of beneficial ownership of,
or beneficial interests in, the Trust other than the Securities;

         (g) incur any indebtedness for borrowed money; or




                                       19



         (h) (i) direct the time,  method and place of  exercising  any trust or
power conferred upon the Debenture Trustee with respect to the Debentures,  (ii)
waive any past default  that is waivable  under  Section 6.06 of the  Indenture,
(iii) exercise any right to rescind or annul any declaration  that the principal
of all of the  Debentures  shall  be due  and  payable  or (iv)  consent  to any
amendment, modification or termination of the Indenture or the Debentures, where
such  consent  shall be  required,  unless  in the case of this  clause  (h) the
Property  Trustee  shall have  received  an  unqualified  opinion of  nationally
recognized  independent tax counsel  recognized as expert in such matters to the
effect  that such action  will not cause the Trust to be  classified  for United
States federal income tax purposes as an association taxable as a corporation or
partnership and that the Trust will continue to be classified as a grantor trust
for United States federal income tax purposes.

         SECTION 3.10. Powers and Duties of the Property Trustee.  (a) The legal
title to the Debentures  shall be owned by and held of record in the name of the
Property  Trustee in trust for the  benefit of the Trust and the  Holders of the
Securities.  The  right,  title and  interest  of the  Property  Trustee  to the
Debentures  shall  vest  automatically  in  each  Person  who may  hereafter  be
appointed  as Property  Trustee in  accordance  with Article 5. Such vesting and
cessation of title shall be effective whether or not conveyancing documents have
been executed and delivered.

         (b) The  Property  Trustee  shall not  transfer  its  right,  title and
interest in the Debentures to the Regular  Trustees or, if the Property  Trustee
does not also act as the Delaware Trustee, the Delaware Trustee.

         (c) The Property Trustee shall:

              (i) establish and maintain a segregated  non-interest bearing bank
         account (the "Property Account") in the name of and under the exclusive
         control  of the  Property  Trustee  on  behalf  of the  Holders  of the
         Securities  and on the  receipt of payments of funds made in respect of
         the Debentures  held by the Property  Trustee,  deposit such funds into
         the  Property  Account  and,  without any further  acts of the Property
         Trustee or the Regular Trustees,  promptly make payments to the Holders
         of the Preferred  Securities  and Common  Securities  from the Property
         Account in accordance with Section 6.01.  Funds in the Property Account
         shall be held uninvested,  and without  liability for interest thereon,
         until  disbursed  in  accordance  with this  Declaration.  The Property
         Account  shall  be an  account  which  is  maintained  with  a  banking
         institution  whose  long  term  unsecured  indebtedness  is  rated by a
         "nationally recognized  statistical rating organization",  as such term
         is defined for purposes of Rule




                                       20




         436(g)(2) under the Securities Act, at least equal to (but in no  event
         less than "A" or the  equivalent) the rating assigned to the  Preferred
         Securities by a nationally recognized statistical rating  organization;

              (ii) engage in such  ministerial  activities as shall be necessary
         or  appropriate  to effect  promptly the  redemption  of the  Preferred
         Securities  and the Common  Securities to the extent the Debentures are
         redeemed or mature;

              (iii) upon notice of distribution  issued by the Regular  Trustees
         in accordance with the terms of the Preferred Securities and the Common
         Securities, engage in such ministerial activities as shall be necessary
         or appropriate to effect promptly the distribution pursuant to terms of
         the  Securities  of  Debentures  to  Holders  of  Securities  upon  the
         occurrence of a Special Event; and

              (iv) have the legal  power to exercise  all of the rights,  powers
         and privileges of a holder of the  Debentures  under the Indenture and,
         if an Event of Default occurs and is continuing,  the Property Trustee,
         subject to Section 2.06(b), shall for the benefit of the Holders of the
         Securities,  enforce its rights as holder of the  Debentures  under the
         Indenture,  subject  to the  rights  of the  Holders  of the  Preferred
         Securities  pursuant  to the terms of this  Declaration,  the  Business
         Trust Act and the Trust Indenture Act.

         (d) The Property Trustee shall take all actions and perform such duties
as may be specifically required of the Property Trustee pursuant to the terms of
the Securities set forth in Exhibits B and C hereto.

         (e) The Property  Trustee  shall take any Legal Action which arises out
of or in connection  with an Event of Default or the Property  Trustee's  duties
and  obligations  under this  Declaration,  the Business  Trust Act or the Trust
Indenture Act; provided  however,  that the holders of a Majority in liquidation
amount of the  Preferred  Securities  will  have the  right to direct  the time,
method and place of conducting any  proceeding  for any remedy  available to the
Property  Trustee or to direct the exercise of any trust or power conferred upon
the Property  Trustee under the  Declaration,  including the right to direct the
Property  Trustee to exercise  the  remedies  available to it as a holder of the
Debentures.  If the  Property  Trustee  fails to enforce  its  rights  under the
Debentures,  a Holder of Preferred  Securities,  to the extent permitted by law,
may institute a legal  proceeding  directly  against AES to enforce the Property
Trustee's  rights  under the  Debentures  without  first  instituting  any legal
proceeding  against the Property Trustee or any other Person;  provided further,
that, if an Event of Default has occurred and is continuing and




                                       21



such event is  attributed  to the  failure of the  Sponsor  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  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 will be subrogated to
the rights of such Holder of Preferred  Securities  to the extent of any payment
made by the  Sponsor to such  Holders of  Preferred  Securities  in such  Holder
Direct  Action.  Except as provided in the preceding  sentences,  the Holders of
Preferred  Securities will not be able to exercise directly any remedy available
to the Holders of the Debentures.

         (f) All moneys  deposited in the Property  Account,  and all Debentures
held by the  Property  Trustee for the benefit of the Holders of the  Securities
will not be subject to any right,  charge,  security interest,  lien or claim of
any kind in favor of, or for the benefit of the  Property  Trustee or its agents
or their creditors.

         (g) The Property Trustee shall,  within 90 days after the occurrence of
a default with respect to the Securities known to the Property Trustee, transmit
by mail, first class postage prepaid, to the holders of the Securities, as their
names and addresses  appear upon the register,  notice of all such defaults with
respect to the Securities, unless such defaults shall have been cured before the
giving of such  notice (the term  "defaults"  for the  purposes of this  Section
3.10(g) being hereby defined to be an Indenture Event of Default,  not including
any periods of grace  provided  for in the  Indenture  and  irrespective  of the
giving of any notice provided  therein);  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,  the Property  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 Property
Trustee in good faith  determines  that the withholding of such notice is in the
interests of the Holders of the  Securities.  The Property  Trustee shall not be
deemed to have knowledge of any default,  except (i) a default in the payment of
principal, premium or interest on the Debentures or (ii) any default as to which
the Property Trustee shall have received written notice or a Responsible Officer
charged with the  administration of this Declaration shall have obtained written
notice.

         (h) The Property  Trustee  shall  continue to serve as a Trustee  until
either:




                                       22



              (i) the  Trust has been  completely  liquidated  and the  proceeds
         thereof  distributed to the Holders of Securities pursuant to the terms
         of the Securities; or

              (ii) a Successor  Property Trustee has been appointed and accepted
         that appointment in accordance with Article 5.

         (i) The  Property  Trustee  shall act as paying agent in respect of the
Common Securities and the Preferred  Securities and, subject to Section 3.08(r),
may authorize one or more Persons (each, a "Paying Agent") to pay Distributions,
redemption payments or liquidation  payments on behalf of the Trust with respect
to the Preferred Securities.  Any such Paying Agent shall comply with ss. 317(b)
of the Trust  Indenture  Act.  Any Paying  Agent may be removed by the  Property
Trustee,  after  consultation  with  the  Regular  Trustees,  at any  time and a
successor Paying Agent or additional  Paying Agents may be appointed at any time
by the Property Trustee, subject to Section 3.08(r).

         (j) The  Property  Trustee  shall  give  prompt  written  notice to the
Holders of the Securities of any notice  received by it from AES of its election
to defer  payments of interest  on the  Debentures  by  extending  the  interest
payment period with respect thereto.

         (k) Subject to this Section 3.10, the Property  Trustee shall have none
of the powers or the  authority  of the  Regular  Trustees  set forth in Section
3.08.

         (l) The Property  Trustee shall exercise the powers,  duties and rights
set forth in this Section 3.10 and Section 3.12 in a manner which is  consistent
with the purposes and  functions of the Trust set out in Section  3.05,  and the
Property  Trustee  shall  not take any  action  which is  inconsistent  with the
purposes and functions of the Trust set forth in Section 3.05.

         SECTION 3.11. Delaware Trustee.  Notwithstanding any other provision of
this Declaration other than Section  5.01(a)(3),  the Delaware Trustee shall not
be entitled to exercise any powers,  nor shall the Delaware  Trustee have any of
the  duties  and  responsibilities  described  in this  Declaration  (except  as
required  under  the  Business  Trust  Act) .  Except  as set  forth in  Section
5.01(a)(3),  the  Delaware  Trustee  shall be a Trustee for the sole and limited
purpose of fulfilling the requirements of ss. 3807 of the Business Trust Act. No
implied covenants or obligations shall be read into this Declaration against the
Delaware Trustee.

         SECTION 3.12.  Certain Rights and Duties of the Property  Trustee.  (a)
The Property Trustee, before the occurrence of an Event of Default and after the
curing of all Events of  Default  that may have  occurred,  shall  undertake  to
perform only




                                       23



such duties as are  specifically set forth in this  Declaration,  and no implied
covenants shall be read into this Declaration  against the Property Trustee.  In
case an Event of  Default  has  occurred  (that  has not  been  cured or  waived
pursuant to Section  2.06),  the Property  Trustee  shall  exercise  such of the
rights and powers vested in it by this  Declaration,  and use the same degree of
care and skill in their  exercise,  as a prudent  person  would  exercise or use
under the circumstances in the conduct of his or her own affairs.

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

              (i) prior to the  occurrence  of an Event of Default and after the
         curing or waiving of all such Events of Default that may have occurred:

                   (A) the duties and obligations of the Property  Trustee shall
              be   determined   solely  by  the  express   provisions   of  this
              Declaration,  and the Property  Trustee shall not be liable except
              for  the  performance  of  such  duties  and  obligations  as  are
              specifically  set  forth  in  this  Declaration,  and  no  implied
              covenants  or  obligations  shall be read  into  this  Declaration
              against the Property Trustee; and

                   (B) in the  absence of bad faith on the part of the  Property
              Trustee,  the Property  Trustee may  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 Property  Trustee and conforming to the  requirements  of this
              Declaration;  but in the case of any such certificates or opinions
              that by any  provision  hereof  are  specifically  required  to be
              furnished to the Property  Trustee,  the Property Trustee shall be
              under a duty to examine the same to determine  whether or not they
              conform to the requirements of this Declaration;

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

              (iii) the Property 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 as provided  herein  relating to the
         time,  method and place of  conducting  any  proceeding  for any remedy
         available to the




                                       24



         Property Trustee  hereunder or under the Indenture,  or exercising  any
         trust  or  power  conferred  upon  the  Property  Trustee  under   this
         Declaration; and

              (iv) no provision of this  Declaration  shall require the Property
         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 it shall have  reasonable
         ground for  believing  that the repayment of such funds or liability is
         not  reasonably  assured to it under the terms of this  Declaration  or
         adequate  indemnity  against such risk or  liability is not  reasonably
         assured to it.

         (c) Subject to the provisions of Section 3.12(a) and (b):

              (i)  whenever  in the  administration  of  this  Declaration,  the
         Property  Trustee  shall deem it  desirable  that a matter be proved or
         established   prior  to  taking,   suffering  or  omitting  any  action
         hereunder,  the  Property  Trustee  (unless  other  evidence  is herein
         specifically  prescribed)  may, in the absence of bad faith on its part
         and, if the Trust is excluded from the definition of Investment Company
         solely by means of Rule 3a-7, subject to the requirements of Rule 3a-7,
         request  and rely  upon a  certificate,  which  shall  comply  with the
         provisions of ss. 314(e) of the Trust  Indenture Act, signed by any two
         of the Regular Trustees or by an authorized officer of the Sponsor,  as
         the case may be;

              (ii) The Property  Trustee (A) may consult with counsel (which may
         be counsel to the Sponsor or any of its  Affiliates and may include any
         of its  employees)  selected  by it in good faith and with due care and
         the written  advice or opinion of such  counsel  with  respect to legal
         matters  shall be full and complete  authorization  and  protection  in
         respect of any action  taken,  suffered or omitted by it  hereunder  in
         good faith and in reliance  thereon and in accordance  with such advice
         and  opinion  and  (B)  shall  have  the  right  at any  time  to  seek
         instructions concerning the administration of this Declaration from any
         court of competent jurisdiction;

              (iii) The Property 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  Property  Trustee  shall not be
         responsible  for any  misconduct or negligence on the part of any agent
         or attorney appointed by it in good faith and with due care;

              (iv) The Property Trustee shall be under no obligation to exercise
         any of the  rights or powers  vested in it by this  Declaration  at the
         request or




                                       25




         direction  of any Holders,  unless such Holders  shall have offered  to
         the Property  Trustee  reasonable  security and indemnity  against  the
         costs,   expenses   (including   attorneys'  fees  and  expenses)   and
         liabilities  that  might be  incurred  by it in  complying  with   such
         request or direction;  provided that nothing  contained in this  clause
         (iv) shall relieve the Property  Trustee of the  obligation,  upon  the
         occurrence of an Event of Default (which has not been cured or  waived)
         to  exercise  such  of the  rights  and  powers  vested  in it by  this
         Declaration,  and to use the same  degree  of care  and  skill in  this
         exercise,  as a  prudent  person  would  exercise  or  use  under   the
         circumstances in the conduct of his or her own affairs; and

              (v)  Any  action  taken  by the  Property  Trustee  or its  agents
         hereunder shall bind the Holders of the Securities and the signature of
         the  Property  Trustee  or its agents  alone  shall be  sufficient  and
         effective  to perform  any such  action;  and no third  party  shall be
         required to inquire as to the  authority of the Property  Trustee to so
         act, or as to its  compliance  with any of the terms and  provisions of
         this Declaration,  both of which shall be conclusively evidenced by the
         Property Trustee's or its agent's taking such action.

         SECTION  3.13.  Filing of  Amendments  to  Certificate  of  Trust.  The
Restated  Certificate of Trust as filed with the Secretary of State of the State
of  Delaware  on  November  1, 1996 and  restated  on March 27, 1997 is attached
hereto as Exhibit A. On or after the date of execution of this Declaration,  the
Trustees  shall  cause the filing  with the  Secretary  of State of the State of
Delaware of such  amendments to the  Certificate  of Trust as the Trustees shall
deem necessary or desirable.

         SECTION  3.14.  Execution  of  Documents  by Regular  Trustees.  Unless
otherwise determined by the Regular Trustees and except as otherwise required by

majority  of,  or if there are only  two,  both of,  the  Regular  Trustees  are
authorized to execute and deliver on behalf of the Trust any documents which the
Regular  Trustees have the power and authority to execute or deliver pursuant to
this Declaration.

         SECTION  3.15.  Trustees  Not  Responsible  for Recitals or Issuance of
Securities.  The recitals contained in this Declaration and the Securities shall
be taken as the  statements  of the Sponsor,  and the Trustees do not assume any
responsibility for their correctness. The Trustees make no representations as to
the value or  condition of the  property of the Trust or any part  thereof.  The
Trustees  make no  representations  as to the  validity or  sufficiency  of this
Declaration or the Securities.




                                       26



         SECTION 3.16. Duration of Trust. The Trust, absent termination pursuant

         SECTION 4.01.  Purchase of Common Securities by Sponsor. On the Closing
Date the Sponsor will purchase all of the Common  Securities issued by the Trust
at the same  time as the  Preferred  Securities  to be  issued  on such date are

Trust (including for this purpose the maximum amount of Preferred Securities, if
any,  which may be issued on the Option Closing Date pursuant to the exercise of
the overallotment option set forth in the Purchase Agreement).

         SECTION  4.02.  Expenses.  (a) In  connection  with the purchase of the
Debentures  by the Trust,  the Sponsor,  in its capacity as Sponsor and not as a
Holder,  shall be  responsible  for and shall pay for all debts and  obligations
(other than with  respect to the  Securities)  and all costs and expenses of the
Trust  (including,  but not  limited  to,  costs and  expenses  relating  to the
organization of the Trust,  the issuance of the Preferred  Securities to initial

taxes of the Trust.

          (c) The Sponsor's obligations under this Section 4.02 shall be for the
benefit  of, and shall be  enforceable  by,  any Person to whom any such  debts,
obligations,  costs,  expenses and taxes are owed (a "Creditor")  whether or not
such  Creditor has received  notice  hereof.  Any such  Creditor may enforce the
Sponsor's  obligations  under this Section 4.02 directly against the Sponsor and
the  Sponsor  irrevocably  waives any right or remedy to  require  that any such
Creditor take any action against the Trust or any other Person before proceeding
against the 





                                       27



Sponsor.  The Sponsor  agrees to execute such  additional  agreements  as may be
necessary or desirable  in order to give full effect to the  provisions  of this
Section 4.02.



                                    ARTICLE 5
                                    TRUSTEES

         SECTION  5.01.  Number of Trustees;  Qualifications.  (a) The number of
Trustees initially shall be five (5). At any time (i) before the issuance of the
Securities,  the Sponsor  may, by written  instrument,  increase or decrease the
number of, and  appoint,  remove and  replace the  Trustees,  and (ii) after the
issuance of the  Securities the number of Trustees may be increased or decreased
solely by, and Trustees may be appointed, removed or replaced solely by, vote of
Holders of Common  Securities  representing a Majority in liquidation  amount of
the Common Securities voting as a class; provided that in any case:

              (i) the number of  Trustees  shall be at least five (5) unless the
         Trustee  that acts as the  Property  Trustee  also acts as the Delaware
         Trustee,  in which cases the number of Trustees  shall be at least four
         (4);

              (ii) at least a  majority  of the  Trustees  shall at all times be
         officers, directors or employees of AES;

              (iii) if  required by the  Business  Trust Act,  one Trustee  (the
         "Delaware  Trustee") shall be either a natural person who is a resident
         of the State of Delaware or, if not a natural  person,  an entity which
         has its  principal  place of  business  in the  State of  Delaware  and
         otherwise is permitted to act as a Trustee  hereunder under the laws of
         the State of  Delaware,  except  that if the  Property  Trustee has its
         principal  place of business in the State of Delaware and  otherwise is
         permitted to act as a Trustee  hereunder under the laws of the State of
         Delaware,  then the Property Trustee shall also be the Delaware Trustee
         and Section 3.11 shall have no application; and

              (iv)  there  shall at all times be a  Property  Trustee  hereunder
         which shall satisfy the requirements of Section 5.01(c).

Each of the Regular  Trustees and the Delaware Trustee shall be either a natural
person at least 21 years of age or a legal entity which shall act through one or
more duly appointed representatives.





                                       28



         (b) The initial Regular Trustees shall be:

         William R. Luraschi
         Willard Hoagland
         Barry J. Sharp
         c/o  THE AES CORPORATION
         1001 North 19th Street
         Arlington, Virginia  22209

         (c) There shall at all times be one Trustee which shall act as Property
Trustee. In order to act as Property Trustee hereunder, such Trustee shall:

              (i) not be an Affiliate of the Sponsor;

              (ii) be a corporation or national  banking  association  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,  national  banking  association or Person permitted by the
         Commission to act as an institutional trustee under the Trust Indenture
         Act,  authorized  under such laws to exercise  corporate  trust powers,
         having a combined  capital  and  surplus of at least  $50,000,000,  and
         subject to supervision or examination by Federal, State, Territorial or
         District of Columbia authority. If such corporation or national banking
         association publishes reports of condition at least annually,  pursuant
         to law or to the requirements of the supervising or examining authority
         referred to above,  then for the purposes of this Section  5.01(c)(ii),
         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; and

              (iii)  if  the  Trust  is  excluded  from  the  definition  of  an
         Investment Company solely by reason of Rule 3a-7 and to the extent Rule
         3a-7 requires a trustee having certain  qualifications to hold title to
         the  "eligible  assets"  (as  defined in Rule  3a-7) of the Trust,  the
         Property Trustee shall possess those qualifications.

         If at any  time  the  Property  Trustee  shall  cease  to  satisfy  the
requirements of clauses  (i)-(iii) above, the Property Trustee shall immediately
resign in the manner and with the  effect  set out in  Section  5.02(d).  If the
Property  Trustee has or shall  acquire any  "conflicting  interest"  within the
meaning of ss. 310(b) of the Trust  Indenture Act, the Property  Trustee and the
Holders of the Common  Securities (as if such Holders were the obligor  referred
to in ss. 310(b) of the Trust  Indenture Act) shall in all respects  comply with
the provisions of ss. 310(b) of the Trust Indenture Act. The Preferred Guarantee
shall be deemed to be specifically



                                       29



described  in this  Declaration  for the  purposes  of  clause  (i) of the first
proviso contained in ss. 310(b) of the Trust Indenture Act.

         The initial  Trustee  which shall serve as the Property  Trustee is The
First National Bank of Chicago, a national banking association, whose address is
as set forth in Section 14.01(b).

         (d) The initial  Trustee  which shall serve as the Delaware  Trustee is
First Chicago  Delaware  Inc., a Delaware  corporation,  whose address is as set
forth in Section 14.01(c).

         (e) Any action taken by Holders of Common  Securities  pursuant to this
Article 5 shall be taken at a meeting of Holders of Common  Securities  convened
for such purpose or by written consent as provided in Section 12.02.

         (f) No  amendment  may be made to this  Section 5.01 which would change
any rights with respect to the number,  existence or appointment  and removal of
Trustees, except with the consent of each Holder of Common Securities.

         SECTION 5.02.  Appointment,  Removal and  Resignation of Trustees.  (a)
Subject to Section  5.02(b),  Trustees may be appointed or removed without cause
at any time:

              (i) until the issuance of the  Securities,  by written  instrument
         executed by the Sponsor; and

              (ii) after the issuance of the  Securities  by vote of the Holders
         of a Majority in liquidation  amount of the Common Securities voting as
         a class.

         (b) (i) The Trustee that acts as Property  Trustee shall not be removed
in accordance with Section 5.02(a) until a Successor Property Trustee possessing
the  qualifications  to act as Property  Trustee under Section  5.01(c) has been
appointed and has accepted such  appointment by written  instrument  executed by
such  Successor  Property  Trustee and  delivered to the Regular  Trustees,  the
Sponsor and the Property Trustee being removed; and

              (ii) the  Trustee  that  acts as  Delaware  Trustee  shall  not be
         removed in accordance  with Section  5.02(a) until a successor  Trustee
         possessing the  qualifications to act as Delaware Trustee under Section
         5.1(a)(3) (a "Successor  Delaware  Trustee") has been appointed and has
         accepted such appointment by written instrument executed by such



                                       30



         Successor Delaware Trustee and delivered to the Regular  Trustees,  the
         Sponsor and the Delaware Trustee being removed.

         (c) A Trustee appointed to office shall hold office until his successor
shall have been appointed or until his death, removal or resignation.

         (d) Any  Trustee  may resign  from  office  (without  need for prior or
subsequent  accounting)  by an instrument (a  "Resignation  Request") in writing
signed  by the  Trustee  and  delivered  to the  Sponsor  and the  Trust,  which
resignation  shall take effect upon such  delivery or upon such later date as is
specified therein; provided, however, that:

              (i) no such  resignation  of the Trustee that acts as the Property
         Trustee shall be effective until:

                   (A)   a   Successor    Property   Trustee    possessing   the
              qualifications  to act as Property  Trustee under Section  5.01(c)
              has been appointed and has accepted such appointment by instrument
              executed by such Successor  Property  Trustee and delivered to the
              Trust, the Sponsor and the resigning Property Trustee; or

                   (B) if the  Trust  is  excluded  from  the  definition  of an
              Investment Company solely by reason of Rule 3a-7, until the assets
              of the Trust  have been  completely  liquidated  and the  proceeds
              thereof distributed to the Holders of the Securities; and

              (ii) no such  resignation of the Trustee that acts as the Delaware
         Trustee shall be effective until a Successor  Delaware Trustee has been
         appointed and has accepted such  appointment by instrument  executed by
         such Successor Delaware Trustee and delivered to the Trust, the Sponsor
         and the resigning Delaware Trustee.

         (e) If no  Successor  Property  Trustee or Successor  Delaware  Trustee
shall have been  appointed and accepted  appointment as provided in this Section
5.02 within 60 days after delivery to the Sponsor and the Trust of a Resignation
Request,  the resigning  Property  Trustee or Delaware  Trustee may petition any
court of competent  jurisdiction for appointment of a Successor Property Trustee
or Successor  Delaware  Trustee.  Such court may thereupon after such notice, if
any, as it may deem proper and prescribe,  appoint a Successor  Property Trustee
or Successor Delaware Trustee, as the case may be.




                                       31



         SECTION 5.03.  Vacancies  among  Trustees.  If a Trustee ceases to hold
office for any reason and the number of  Trustees  is not  reduced  pursuant  to
Section 5.01 or if the number of Trustees is increased pursuant to Section 5.01,
a vacancy shall occur. A resolution  certifying the existence of such vacancy by
a majority of the Regular Trustees shall be conclusive evidence of the existence
of such  vacancy.  The  vacancy  shall be  filled  with a Trustee  appointed  in
accordance with the requirements of this Article 5.

         SECTION 5.04. Effect of Vacancies. The death, resignation,  retirement,
removal,  bankruptcy,  dissolution,  liquidation,  incompetence or incapacity to
perform the duties of a Trustee,  or any one of them, shall not operate to annul
the Trust.  Whenever a vacancy in the  number of Regular  Trustees  shall  occur
until such vacancy is filled as provided in this Article 5, the Regular Trustees
in office,  regardless of their number, shall have all the powers granted to the
Regular  Trustees and shall  discharge  all the duties  imposed upon the Regular
Trustees by this Declaration.

         SECTION 5.05. Meetings.  Meetings of the Regular Trustees shall be held
from time to time upon the call of any Trustee.  Regular meetings of the Regular
Trustees  may be held at a time and place  fixed by  resolution  of the  Regular
Trustees.  Notice of any in-person meeting of the Regular Trustees shall be hand
delivered or otherwise delivered in writing (including by facsimile, with a hard
copy by overnight courier) not less than 48 hours before such meeting. Notice of
any telephonic meeting of the Regular Trustees or any committee thereof shall be
hand delivered or otherwise delivered in writing (including by facsimile, with a
hard copy by  overnight  courier)  not less than 24 hours  before such  meeting.
Notices  shall  contain a brief  statement  of the time,  place and  anticipated
purposes of the meeting.  The presence  (whether in person or by telephone) of a
Regular Trustee at a meeting shall constitute a waiver of notice of such meeting
except  where a Regular  Trustee  attends a meeting for the  express  purpose of
objecting to the  transaction of any activity on the ground that the meeting has
not  been  lawfully  called  or  convened.  Unless  provided  otherwise  in this
Declaration,  any action of the  Regular  Trustees  may be taken at a meeting by
vote of a majority  of the  Regular  Trustees  present  (whether in person or by
telephone)  and eligible to vote with respect to such  matter;  provided  that a
Quorum is present,  or without a meeting by the unanimous written consent of the
Regular Trustees.

         SECTION  5.06.  Delegation  of Power.  (a) Any Regular  Trustee may, by
power of attorney  consistent with applicable law, delegate to any other natural
person  over the age of 21 his or her power for the  purpose  of  executing  any
registration  statement or amendment thereto or other document or schedule filed
with the Commission or making any other governmental filing.




                                       32




         (b) The Regular Trustees shall have power to delegate from time to time
to such of their number or to officers of the Trust the doing of such things and
the execution of such  instruments  either in the name of the Trust or the names
of the Regular Trustees or otherwise as the Regular Trustees may deem expedient,
to the extent such delegation is not prohibited by applicable law or contrary to
the provisions of the Trust, as set forth herein.


                                    ARTICLE 6
                                  DISTRIBUTIONS

         SECTION   6.01.   Distributions.   Holders   shall   receive   periodic
distributions,  redemption payments and liquidation  distributions in accordance
with the applicable terms of the relevant Holder's Securities ("Distributions").
Distributions  shall be made to the Holders of Preferred  Securities  and Common
Securities  in  accordance  with the  terms of the  Securities  as set  forth in
Exhibits  B and C hereto.  If and to the  extent  that AES  makes a  payment  of
interest (including Compounded Interest (as defined in the Indenture)),  premium
and principal on the Debentures held by the Property  Trustee (the amount of any
such  payment  being a "Payment  Amount"),  the  Property  Trustee  shall and is
directed to promptly  make a  Distribution  of the Payment  Amount to Holders in
accordance  with the terms of the  Securities  as set forth in  Exhibits B and C
hereto.


                                    ARTICLE 7
                             ISSUANCE OF SECURITIES

         SECTION 7.01. General Provisions Regarding Securities.  (a) The Regular
Trustees shall issue on behalf of the Trust  securities  representing  undivided
beneficial  interests  in the  assets of the Trust in  accordance  with  Section
7.01(b) and for the consideration specified in Section 3.03.

         (b) The Regular  Trustees  shall issue on behalf of the Trust one class
of  preferred  securities  representing  undivided  beneficial  interests in the
assets  of the  Trust  having  such  terms as are set  forth in  Exhibit  B (the
"Preferred Securities") which terms are incorporated by reference in, and made a
part of, this Declaration as if specifically set forth herein,  and one class of
common securities  representing  undivided beneficial interests in the assets of
the  Trust  having  such  terms  as are set  forth  in  Exhibit  C (the  "Common
Securities")  which terms are  incorporated by reference in, and made a part of,
this Declaration as if specifically set forth herein.




                                       33



The Trust shall have no securities or other interests in the assets of the Trust
other than the Preferred Securities and the Common Securities.

         (c) The  Certificates  shall be  signed  on  behalf of the Trust by the
Regular  Trustees (or if there are more than two Regular  Trustees by any two of
the Regular Trustees). Such signatures may be the manual or facsimile signatures
of the  present or any future  Regular  Trustee.  Typographical  and other minor
errors or  defects  in any such  reproduction  of any such  signature  shall not
affect the validity of any Certificate. In case any Regular Trustee of the Trust
who shall have signed any of the  Certificates  shall  cease to be such  Regular
Trustee before the  Certificate so signed shall be delivered by the Trust,  such
Certificate  nevertheless  may be delivered as though the person who signed such
Certificate had not ceased to be such Regular  Trustee;  and any Certificate may
be signed on behalf of the Trust by such  persons  as, at the actual date of the
execution  of such  Certificate,  shall be the  Regular  Trustees  of the Trust,
although at the date of the execution and delivery of the  Declaration  any such
person  was  not  such  a  Regular  Trustee.   Certificates  shall  be  printed,
lithographed or engraved or may be produced in any other manner as is reasonably
acceptable to the Regular Trustees, as evidenced by their execution thereof, and
may have such letters,  numbers or other marks of  identification or designation
and such legends or endorsements as the Regular  Trustees may deem  appropriate,
or as may be required to comply with any law or with any rule or regulation made
pursuant  thereto or with any rule or regulation of any stock  exchange on which
Securities  may be listed,  or to conform to usage.  Pending the  preparation of
definitive Certificates, the Regular Trustees on behalf of the Trust may execute
temporary Certificates (printed,  lithographed or typewritten), in substantially
the form of the definitive  Certificates  in lieu of which they are issued,  but
with  such  omissions,  insertions  and  variations  as may be  appropriate  for
temporary  Certificates,  all as may be determined by the Regular Trustees. Each
temporary Certificate shall be executed by the Regular Trustees on behalf of the
Trust upon the same conditions and in  substantially  the same manner,  and with
like effect, as definitive Certificates.  Without unnecessary delay, the Regular
Trustees on behalf of the Trust will execute and furnish definitive Certificates
and  thereupon  any or all  temporary  Certificates  may be  surrendered  to the
transfer  agent  and  registrar  in  exchange  therefor  (without  charge to the
Holders).  Each  Certificate  whether in temporary or  definitive  form shall be
countersigned by the manual or facsimile signature of an authorized signatory of
the Person  acting as registrar  and transfer  agent for the  Securities,  which
shall initially be the Property Trustee.

         (d) The  consideration  received  by the Trust for the  issuance of the
Securities shall constitute a contribution to the capital of the Trust and shall
not constitute a loan to the Trust.

         (e) Upon issuance of the  Securities  as provided in this  Declaration,
the  Securities so issued shall be deemed to be validly  issued,  fully paid and
non-assessable.

         (f) Every  Person,  by virtue of having  become a Holder or a Preferred
Security  Beneficial  Owner in  accordance  with the terms of this  Declaration,
shall be deemed to have expressly assented and agreed to the terms of, and shall
be bound by this Declaration.

         (g) Upon issuance of the  Securities  as provided in this  Declaration,
the  Regular  Trustees  on  behalf  of the  Trust  shall  return  to AES the $10
constituting initial trust assets as set forth in the Original Declaration.

         SECTION 7.02.  Conversion  Agent. The Trust shall maintain an office or
agency where Preferred  Securities may be presented for conversion  ("Conversion
Agent").  The Trust may appoint the Conversion Agent and may appoint one or more
additional  Conversion  Agents in such other locations as it may determine.  The
term "Conversion Agent" includes any additional  Conversion Agent. The Trust may
change any  Conversion  Agent without prior notice to any Holders.  If the Trust
fails to appoint or maintain  another entity as Conversion  Agent,  the Property
Trustee  will  act as  such.  The  Trust  or any of its  Affiliates  may  act as
Conversion  Agent.  The Trust  shall  act as  Conversion  Agent  for the  Common
Securities. The Conversion Agent shall be entitled to the rights and protections
extended to the Property Trustee when acting in such capacity.

         The Property Trustee is hereby initially  appointed as Conversion Agent
for the Preferred Securities.

         SECTION 8.01.  Termination  of Trust.  This  Declaration  and the Trust
shall terminate and be of no further force or effect when:

         (a) all of the Securities shall have been called for redemption and the
amounts necessary for redemption  thereof shall have been paid to the Holders of
Securities in accordance with the terms of the Securities; or

         (b) all of the Debentures shall have been distributed to the Holders of
Securities in exchange for all of the Securities in accordance with the terms of
the Securities; or



                                       35



         (c)  upon the  expiration  of the  term of the  Trust  as set  forth in
Section 3.16; or,

         (d)  upon  the  distribution  of  the  Sponsor's  common  stock  to all
Securities Holders upon conversion of all outstanding Preferred Securities,

and a certificate of cancellation is filed by the Trustees with the Secretary of
State of the State of Delaware. The Trustees shall so file such a certificate as
soon as practicable after the occurrence of an event referred to in this Section
8.01.

         The  provisions  of Sections 3.12 and 4.02 and Article 10 shall survive
the termination of the Trust.


                                    ARTICLE 9

                              TRANSFER OF INTERESTS

         SECTION  9.01.  Transfer  of  Securities.  (a)  Securities  may only be
transferred,  in whole or in part, in accordance  with the terms and  conditions
set  forth in this  Declaration.  Any  transfer  or  purported  transfer  of any
Security not made in accordance with this Declaration shall be null and void.

          (b) Subject to this Article 9,  Preferred  Securities  shall be freely
transferable.

          (c)  Subject  to this  Article 9, AES and any  Related  Party may only
transfer  Common  Securities to AES or a Related  Party;  provided that any such
transfer  shall be  subject  to the  condition  that the  transferor  shall have
obtained (1) either a ruling from the Internal Revenue Service or an unqualified
written  opinion  addressed  to the  Trust  and  delivered  to the  Trustees  of
nationally recognized independent tax counsel experienced in such matters to the
effect that such  transfer will not (i) cause the Trust to be treated as issuing
a class  of  interests  in the  Trust  differing  from the  class  of  interests
represented by the Common  Securities  originally  issued to AES, (ii) result in
the Trust  acquiring  or  disposing  of, or being  deemed  to have  acquired  or
disposed  of, an asset,  or (iii)  result in or cause the Trust to be treated as
anything  other  than a grantor  trust for  United  States  federal  income  tax
purposes  and (2) an  unqualified  written  opinion  addressed  to the Trust and
delivered  to  the  Trustees  of a  nationally  recognized  independent  counsel
experienced in such matters that such transfer will not cause the Trust to be an
Investment Company or controlled by an Investment Company.




                                       36



         (d) Each  Security  that  bears or is  required  to bear the legend set
forth in this Section 9.01(d) (a "Restricted  Security") shall be subject to the
restrictions  on  transfer  provided  in the  legend  set forth in this  Section
9.01(d),  unless such  restrictions  on transfer  shall be waived by the written
consent of the Regular Trustees,  and the Holder of each Restricted Security, by
such   securityholder's   acceptance  thereof,   agrees  to  be  bound  by  such
restrictions on transfer.  As used in this Section 9.01(d),  the term "transfer"
encompasses any sale,  pledge,  transfer or other  disposition of any Restricted
Security.

         Prior to the Transfer  Restriction  Termination  Date,  the 144A Global
Security,  Temporary  Regulation S Global  Security,  each Definitive  Preferred
Security and any  certificate  evidencing  Common  Stock issued upon  conversion
thereof  shall  bear a  legend  in  substantially  the  following  form,  unless
otherwise  agreed by the Regular  Trustees  (with written  notice thereof to the
Indenture Trustee):

              THIS SECURITY HAS NOT BEEN  REGISTERED  UNDER THE U.S.  SECURITIES
              ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND,  ACCORDINGLY,
              MAY NOT BE  OFFERED OR SOLD  EXCEPT AS SET FORTH IN THE  FOLLOWING
              SENTENCE.  BY ITS  ACQUISITION  HEREOF,  THE HOLDER (1) REPRESENTS
              THAT (A) IT IS A  "QUALIFIED  INSTITUTIONAL  BUYER" (AS DEFINED IN
              RULE 144A UNDER THE SECURITIES  ACT),  (B) IT IS AN  INSTITUTIONAL
              "ACCREDITED INVESTOR" IN RULE 501(a)(1), (2), (3) OR (7) UNDER THE
              SECURITIES ACT (AN "INSTITUTIONAL  ACCREDITED INVESTOR")),  OR (C)
              IT IS NOT A U.S.  PERSON  AND IS  ACQUIRING  THIS  SECURITY  IN AN
              OFFSHORE  TRANSACTION,  (2)  AGREES  THAT IT WILL NOT PRIOR TO THE
              EXPIRATION  OF THE  HOLDING  PERIOD  APPLICABLE  TO  SALES  OF THE
              SECURITY  EVIDENCED  HEREBY UNDER RULE 144(k) UNDER THE SECURITIES
              ACT (OR ANY  SUCCESSOR  PROVISION),  RESELL OR OTHERWISE  TRANSFER
              THIS SECURITY  EXCEPT (A) TO AES OR ANY  SUBSIDIARY  THEREOF,  (B)
              INSIDE THE UNITED  STATES TO A  QUALIFIED  INSTITUTIONAL  BUYER IN
              COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) INSIDE THE
              UNITED STATES TO AN INSTITUTIONAL ACCREDITED INVESTOR THAT, BEFORE
              SUCH TRANSFER



                                       37


              FURNISHES   THE  TRUSTEE  A  SIGNED  LETTER   CONTAINING   CERTAIN
              REPRESENTATIONS  AND AGREEMENTS  RELATING TO THE  RESTRICTIONS  ON
              TRANSFER  OF THIS  SECURITY  (THE  FORM  OF  WHICH  LETTER  CAN BE
              OBTAINED  FROM THE TRUSTEE) AND IF SUCH  TRANSFER IS IN RESPECT OF
              AN AGGREGATE PRINCIPAL AMOUNT OF SECURITIES LESS THAN $250,000, AN
              OPINION OF COUNSEL  ACCEPTABLE  TO THE TRUST THAT SUCH TRANSFER IS
              IN  COMPLIANCE  WITH THE  SECURITIES  ACT,  (D) OUTSIDE THE UNITED
              STATES IN AN  OFFSHORE  TRANSACTION  IN  COMPLIANCE  WITH RULE 904
              UNDER THE  SECURITIES  ACT,  (E)  PURSUANT TO THE  EXEMPTION  FROM
              REGISTRATION  PROVIDED  BY RULE 144 UNDER THE  SECURITIES  ACT (IF
              AVAILABLE) OR (F) PURSUANT TO AN EFFECTIVE  REGISTRATION STATEMENT
              UNDER THE  SECURITIES  ACT AND (3) AGREES THAT IT WILL  DELIVER TO
              EACH  PERSON  TO  WHOM  THIS  SECURITY  IS  TRANSFERRED  A  NOTICE
              SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY
              TRANSFER  OF THIS  SECURITY  PRIOR TO THE  EXPIRATION  DATE OF THE
              HOLDING  PERIOD  APPLICABLE  TO  SALES OF THE  SECURITY  EVIDENCED
              HEREBY  UNDER  RULE  144(k)  UNDER  THE  SECURITIES  ACT  (OR  ANY
              SUCCESSOR  PROVISION),  THE TRANSFEROR  MUST CHECK THE APPROPRIATE
              BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH
              TRANSFER AND SUBMIT THIS CERTIFICATE TO THE PROPERTY  TRUSTEE.  IF
              THE PROPOSED TRANSFEREE IS AN INSTITUTIONAL  ACCREDITED  INVESTOR,
              THE TRANSFEROR MUST,  BEFORE SUCH TRANSFER,  FURNISH TO THE ISSUER
              SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS IT MAY
              REASONABLY  REQUIRE TO CONFIRM  THAT SUCH  TRANSFER  IS BEING MADE
              PURSUANT TO AN EXEMPTION FROM OR IN A TRANSACTION  NOT SUBJECT TO,
              THE  REGISTRATION  REQUIREMENTS  OF THE  SECURITIES  ACT.  AS USED
              HEREIN,  THE TERMS



                                       38



              "OFFSHORE TRANSACTION", "UNITED STATES" AND "U.S. PERSON" HAVE THE
              MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

         Following the Transfer  Restriction  Termination  Date or the sale of a
Security or Common Stock for which a Security has been exchanged  pursuant to an
effective registration statement or Rule 144, any Security or security issued in
exchange or  substitution  therefor  (other than (i) Securities  acquired by the
Sponsor or any  Affiliate  and (ii) Common Stock issued upon the  conversion  or
exchange of any Security  described  in clause (i) above) may upon  surrender of
such  Security  for  exchange to any  Regular  Trustee on behalf of the Trust in
accordance with the provisions of this Section  9.01(d),  be exchanged for a new
Security or Securities,  of like tenor and aggregate  liquidation amount,  which
shall not bear the restrictive legend required by this Section 9.01(d).

         SECTION 9.02.  Transfer of  Certificates.  The Regular  Trustees  shall
provide for the  registration of Certificates  and of transfers of Certificates,
which will be effected without charge but only upon payment (with such indemnity
as the Regular  Trustees may require) in respect of any tax or other  government
charges which may be imposed in relation to it. Upon surrender for  registration
of transfer of any Certificate, the Regular Trustees shall cause one or more new
Certificates  to  be  issued  in  the  name  of  the  designated  transferee  or
transferees. Every Certificate surrendered for registration of transfer shall be
accompanied  by a written  instrument  of transfer in form  satisfactory  to the
Regular  Trustees  duly  executed by the Holder or such  Holder's  attorney duly
authorized in writing. Each Certificate surrendered for registration of transfer
shall be canceled by the Regular  Trustees.  A transferee of a Certificate shall
be entitled to the rights and subject to the  obligations of a Holder  hereunder
upon the  receipt  by such  transferee  of a  Certificate.  By  acceptance  of a
Certificate,  each transferee shall be deemed to have agreed to be bound by this
Declaration.

         SECTION  9.03.  Deemed  Security  Holders.  The  Trustees may treat the
Person  in whose  name any  Certificate  shall be  registered  on the  books and
records  of  the  Trust  as the  sole  holder  of  such  Certificate  and of the
Securities   represented   by  such   Certificate   for  purposes  of  receiving
Distributions and for all other purposes whatsoever and, accordingly,  shall not
be bound to  recognize  any  equitable  or other  claim to or  interest  in such
Certificate or in the Securities  represented by such Certificate on the part of
any  Person,  whether  or not the  Trustees  shall have  actual or other  notice
thereof.





                                       39



         SECTION 9.04. Book Entry  Interests.  (a) Except as provided in Section
9.07 and unless  otherwise  specified in the terms of the Preferred  Securities,
the Preferred Securities Certificates, on original issuance (including Preferred
Securities,  if any,  issued on the Option Closing Date pursuant to the exercise
of the overallotment option set forth in the Purchase Agreement), will be issued
in  the  form  of one or  more,  fully  registered,  global  Preferred  Security
Certificates (each a "Global Certificate"),  to be delivered to DTC, the initial
Clearing Agency, by, or on behalf of, the Trust. Such Global  Certificates shall
initially  be  registered  on the books and  records of the Trust in the name of
Cede & Co., the nominee of DTC, and no Preferred Security  Beneficial Owner will
receive a definitive Preferred Security Certificate  representing such Preferred
Security  Beneficial  Owner's interests in such Global  Certificates,  except as
provided in Section 9.07.

         (b) Preferred  Securities that upon initial  issuance are  beneficially
owned by QIBs may,  at the option of the Trust,  be  represented  by one or more
Global  Certificates (a "144A Global Security"),  and Preferred  Securities that
upon initial  issuance are  beneficially  owned by Non-U.S.  Persons may, at the
option of the  Trust,  be  represented  by one or more  Global  Certificates  (a
"Temporary  Regulation S Global Security").  At any time on or after December 9,
1997 (the "Regulation S Securities Exchange Date"), one or more permanent Global
Certificates  without the legend set forth in Section  9.01(d)  (the  "Permanent
Regulation S Global  Security",  and together  with the  Temporary  Regulation S
Global Security,  the "Regulation S Global  Securities") shall be deposited with
the Clearing Agency, and the Property Trustee shall make endorsements reflecting
a decrease in the principal amount of the Temporary Regulation S Global Security
in an amount equal to the  principal  amount of the  beneficial  interest in the
Temporary  Regulation S Global Security  transferred.  Transfers of interests in
the Preferred  Securities  between any 144A Global Security and any Regulation S
Global  Security will be made in accordance with the standing  instructions  and
procedures of the Clearing  Agency and its  participants.  The Property  Trustee
shall make  appropriate  endorsements  to reflect  increases or decreases in the
amount  of such  Preferred  Securities  in  global  form  to  reflect  any  such
transfers.

         Except as provided below,  beneficial owners of a Preferred Security in
global  form shall not be  entitled  to have  certificates  registered  in their
names,  will  not  receive  or be  entitled  to  receive  physical  delivery  of
certificates  in  definitive  form and will not be  considered  Holders  of such
Preferred Security in global form.

         Any transfer of a beneficial interest in a Preferred Security in global
form which cannot be effected through book-entry  settlement must be effected by
the  delivery  to the  transferee  (or its  nominee) of a  Definitive  Preferred
Security Certificate or Definitive Preferred Security Certificates registered in
the name of




                                       40



the transferee (or its nominee) on the books maintained by the Property Trustee.
With  respect  to any  such  transfer,  the  Property  Trustee  will  cause,  in
accordance with the standing instructions and procedures of the Clearing Agency,
the aggregate  principal amount at maturity of the Preferred  Security in global
form to be reduced and,  following such reduction,  the Sponsor will execute and
the Property  Trustee will  authenticate  and make available for delivery to the
transferee  (or such  transferee's  nominee,  as the case may be),  a  Preferred
Security or Securities in the appropriate aggregate principal amount at maturity
in the name of such  transferee  (or its nominee)  and bearing such  restrictive
legends as may be required by this Declaration of Trust.

         (c) So long as the  Preferred  Securities  are eligible for  book-entry
settlement  and to the  extent  Preferred  Securities  held by QIBs or  Non-U.S.
Persons,  as the case may be,  are held in a global  form,  or unless  otherwise
required by law, upon any transfer of a Definitive  Preferred  Security to a QIB
in  accordance  with  Rule  144A or to a  Non-U.S.  Person  in  accordance  with
Regulation S, unless otherwise requested by the transferor,  and upon receipt of
the Definitive  Preferred  Security  Certificate being so transferred,  together
with a  certification  from the  transferor  that the  transfer is being made in
compliance with Rule 144A or Regulation S, as the case may be (or other evidence
satisfactory  to the  Property  Trustee on behalf of the  Trust),  the  Property
Trustee on behalf of the Trust  shall  make an  endorsement  on any 144A  Global
Security or any Regulation S Global Security,  as the case may be, to reflect an
increase  in the  number of  Preferred  Securities  represented  by such  Global
Certificate,  and the Property  Trustee on behalf of the Trust shall cancel such
Definitive  Preferred Security in accordance with the standing  instructions and
procedures  of  the  Clearing  Agency,   the  number  of  Preferred   Securities
represented  by  such  Preferred   Security  in  global  form  to  be  increased
accordingly; provided that no Definitive Preferred Security, or portion thereof,
in respect of which the Trust or an Affiliate  of the Trust held any  beneficial
interest shall be included in such Preferred  Security in global form until such
Definitive Preferred Security is freely tradable in accordance with Rule 144(k);
provided  further that the Trust shall issue Preferred  Securities in definitive
form upon any transfer of a  beneficial  interest in the  Preferred  Security in
global form to the Sponsor or any Affiliate of the Sponsor.

         (d) Any Global Certificate may be endorsed with or have incorporated in
the text thereof such legends or recitals or changes not  inconsistent  with the
provisions of this Declaration as may be required by the Clearing Agency, by any
national  securities  exchange  or by the  National  Association  of  Securities
Dealers,  Inc. in order for the  Preferred  Securities  to be  tradeable  on the
PORTAL Market or as may be required for the Preferred Securities to be tradeable
on any other market developed for trading of securities pursuant to Rule 144A or
required to comply with any applicable law or any regulation  thereunder or with
the rules and





                                       41



regulations of any securities  exchange upon which the Preferred  Securities may
be listed or traded or to conform  with any usage with  respect  thereto,  or to
indicate  any  special  limitations  or  restrictions  to which  any  particular
Preferred Securities are subject. Unless and until definitive,  fully registered
Preferred   Security    Certificates   (the   "Definitive   Preferred   Security
Certificates")  have been issued to the  Preferred  Security  Beneficial  Owners
pursuant to Section 9.07:

              (i) the provisions of this Section 9.04 shall be in full force and
         effect;

              (ii) the Trust and the Trustees shall be entitled to deal with the
         Clearing  Agency for all purposes of this  Declaration  (including  the
         payment of  Distributions  on the  Global  Certificates  and  receiving
         approvals,  votes or consents hereunder) as the Holder of the Preferred
         Securities and the sole holder of the Global  Certificates  and, except
         as set  forth  herein  or in Rule 3a-7  with  respect  to the  Property
         Trustee,  shall have no obligation to the Preferred Security Beneficial
         Owners;  provided,  that solely for the purposes of determining whether
         the Holders of the requisite amount of Preferred  Securities have voted
         on any matter provided for in this  Declaration,  so long as definitive
         Preferred  Security  Certificates  have not been  issued  (pursuant  to
         Section 9.07 hereof),  the Trustees may conclusively rely on, and shall
         be protected in relying on, any written instrument  (including a proxy)
         delivered  to the  Trustees by the Clearing  Agency  setting  forth the
         Preferred  Security  Beneficial Owners' votes or assigning the right to
         vote on any matter to any other Persons either in whole or in part;

              (iii) to the  extent  that the  provisions  of this  Section  9.04
         conflict with any other provisions of this Declaration,  the provisions
         of this Section 9.04 shall control; and

              (iv) the rights of the Preferred Security  Beneficial Owners shall
         be exercised  only through the Clearing  Agency and shall be limited to
         those established by law and agreements between such Preferred Security
         Beneficial  Owners and the Clearing  Agency and/or the Clearing  Agency
         Participants.  DTC will make book entry  transfers  among the  Clearing
         Agency  Participants and receive and transmit payments of Distributions
         on the Global Certificates to such Clearing Agency Participants.

         SECTION 9.05. Notices to Holders of Certificates.  Whenever a notice or
other  communication  to  the  Holders  is  required  to  be  given  under  this
Declaration,  unless and until Definitive Preferred Security  Certificates shall
have been issued pursuant to Section 9.07, the relevant  Trustees shall give all
such  notices  and




                                       42



communications, specified herein to be given to Preferred Securities Holders, to
the Clearing  Agency and,  with respect to any  Preferred  Security  Certificate
registered in the name of a Clearing Agency or the nominee of a Clearing Agency,
the Trustees  shall,  except as set forth herein or in Rule 3a-7 with respect to
the Property  Trustee,  have no notice  obligations  to the  Preferred  Security
Beneficial Owners.

         SECTION 9.06. Appointment of Successor Clearing Agency. If any Clearing
Agency elects to discontinue its services as securities  depository with respect
to the Preferred Securities, the Regular Trustees may, in their sole discretion,
appoint a successor Clearing Agency with respect to the Preferred Securities.

         SECTION 9.07. Definitive Preferred Securities Certificates.  (a) If (i)
a Clearing  Agency elects to discontinue  its services as securities  depository
with respect to the Preferred  Securities and a successor Clearing Agency is not
appointed within 90 days after such  discontinuance  pursuant to Section 9.06 or
(ii) the Regular Trustees elect after consultation with the Sponsor to terminate
the book entry system through the Clearing  Agency with respect to the Preferred
Securities,  then  (x)  Definitive  Preferred  Security  Certificates  shall  be
prepared  by the Regular  Trustees  on behalf of the Trust with  respect to such
Preferred  Securities and (y) upon surrender of the Global  Certificates  by the
Clearing Agency, accompanied by registration instructions,  the Regular Trustees
shall cause  definitive  Preferred  Security  Certificates  to be  delivered  to
Preferred Security  Beneficial Owners in accordance with the instructions of the
Clearing  Agency.  Neither  the  Trustees  nor the Trust shall be liable for any
delay indelivery of such  instructions and each of them may conclusively rely on
and shall be protected in relying on, such instructions.

         (b) Restricted  Securities that upon initial  issuance are beneficially
owned by, or are subsequently transferred to, Institutional Accredited Investors
that  are  neither  QIBs nor  Non-U.S.  Persons  will be  issued  as  Definitive
Preferred  Security  Certificates  and  may  not  be  represented  by  a  Global
Certificate.  Preferred  Securities that upon initial  issuance are beneficially
owned by Persons that are Non-U.S.  Persons may, at the option of the Trust,  be
issued as  Definitive  Preferred  Security  Certificates.  Definitive  Preferred
Security  Certificates  issued  in  exchange  for all or a part  of a  Preferred
Security in global form shall be registered in such names and in such authorized
denominations as the Clearing Agency,  pursuant to instructions  from its direct
or indirect participants or otherwise, shall instruct the Property Trustee. Upon
execution and  authentication,  the Property  Trustee  shall make  available for
delivery such Definitive Preferred Security  Certificates to the person in whose
name such Definitive Preferred Security  Certificates are so registered.  In the
case of transfers to Institutional




                                       43



Accredited Investors,  the Property Trustee shall make appropriate  endorsements
to reflect decreases in the amount of the applicable Global Certificate.

         SECTION 9.08. Mutilated, Destroyed, Lost or Stolen Certificates. If (a)
any mutilated  Certificates should be surrendered to the Regular Trustees, or if
the  Regular  Trustees  shall  receive  evidence  to their  satisfaction  of the
destruction,  loss or theft of any Certificate; and (b) there shall be delivered
to the Regular Trustees such security or indemnity as may be required by them to
keep each of them harmless,  then in the absence of notice that such Certificate
shall have been acquired by a bona fide purchaser,  any two Regular  Trustees on
behalf of the Trust shall execute and deliver, in exchange for or in lieu of any
such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
denomination.  In connection with the issuance of any new Certificate under this
Section 9.08,  the Regular  Trustees may require the payment of a sum sufficient
to cover any tax or other governmental  charge that may be imposed in connection
therewith.  Any  duplicate  Certificate  issued  pursuant to this section  shall
constitute  conclusive  evidence  of  an  ownership  interest  in  the  relevant
Securities,  as if  originally  issued,  whether  or not  the  lost,  stolen  or
destroyed Certificate shall be found at any time.


                                   ARTICLE 10
                    LIMITATION OF LIABILITY; INDEMNIFICATION

         SECTION 10.01. Exculpation.  (a) No Indemnified Person shall be liable,

negligence  (but,  in the case of the  Property  Trustee,  subject  to the Trust
Indenture Act) or willful misconduct with respect to such acts or omissions.

          (b) An Indemnified  Person shall be fully protected in relying in good
faith upon the records of the Trust and upon such information, opinions, reports

existence and amount of assets from which Distributions to Holders of Securities
might properly be paid.

         (c) Pursuant to ss.  3803(a) of the Business  Trust Act, the Holders of
Securities,  in their  capacities  as  Holders,  shall be  entitled  to the same
limitation of liability that is extended to stockholders of private corporations
for profit organized under the General Corporation Law of the State of Delaware.

         SECTION 10.02. Indemnification.  (a) To the fullest extent permitted by
applicable law, the Sponsor shall  indemnify and hold harmless each  Indemnified

         (b) To  the  fullest  extent  permitted  by  applicable  law,  expenses
(including legal fees) incurred by an Indemnified Person in defending any claim,
demand,  action, suit or proceeding shall, from time to time, be advanced by the
Sponsor prior to the final disposition of such claim,  demand,  action,  suit or
proceeding  upon receipt by the Sponsor of an undertaking by or on behalf of the
Indemnified  Person  to repay  such  amount if it shall be  determined  that the
Indemnified  Person is not entitled to be  indemnified  as authorized in Section
10.02(a).

         (c) The provisions of this Section 10.02 shall survive the  termination
of this Declaration or the resignation or removal of any Trustee.

         SECTION 10.03. Outside Business. The Sponsor and any Trustee may engage
in or  possess  an  interest  in  other  business  ventures  of  any  nature  or
description, independently or with others, similar or dissimilar to the business

by virtue of this Declaration in and to such independent  ventures or the income
or profits  derived  therefrom,  and the  pursuit of any such  venture,  even if
competitive  with the  business  of the Trust,  shall not be deemed  wrongful or
improper.  Neither the Sponsor nor any Trustee shall be obligated to present any
particular investment or other opportunity to the Trust even if such opportunity
is of a character that, if presented to the Trust,  could be taken by the Trust,
and the Sponsor or any Trustee  shall have the right to take for its own account





                                       45

particular  investment  or other  opportunity.  Any  Trustee  may  engage  or be
interested  in any  financial  or  other  transaction  with the  Sponsor  or any
Affiliate of the Sponsor or may act as depository for,  trustee or agent for, or
act on any committee or body of holders of,  securities or other  obligations of
the Sponsor or its Affiliates.

                                   ACCOUNTING

         SECTION  11.01.  Fiscal Year.  The fiscal year  ("Fiscal  Year") of the
Trust shall be the calendar year, or such other year as is required by the Code.

         SECTION 11.02.  Certain Accounting Matters. (a) At all times during the
existence of the Trust,  the Regular  Trustees  shall keep, or cause to be kept,
full books of account, records and supporting documents,  which shall reflect in
reasonable detail,  each transaction of the Trust. The books of account shall be
maintained on the accrual  method of  accounting,  in accordance  with generally
accepted accounting  principles,  consistently  applied. The Trust shall use the
accrual method of accounting for United States federal income tax purposes.  The
books and records of the Trust,  together with a copy of this  Declaration and a
certified copy of the Certificate of Trust, or any amendment  thereto,  shall at
all times be maintained  at the principal  office of the Trust and shall be open
for  inspection  for  any  examination  by any  Holder  or its  duly  authorized
representative  for any purpose  reasonably related to its interest in the Trust
during normal business hours.

         (b) The Regular  Trustees shall cause to be prepared and mailed to each
Holder of Securities,  an annual United States  federal  income tax  information
statement,  on such form as is required by the Code, containing such information
with regard to the Securities held by each Holder as is required by the Code and
the Treasury  Regulations.  Notwithstanding  any right under the Code to deliver
any such  statement  at a later date,  the Regular  Trustees  shall  endeavor to
deliver all such statements  within 30 days after the end of each Fiscal Year of
the Trust.

          (c) The Regular Trustees shall cause to be prepared and filed with the

         SECTION  11.03.  Banking.  The Trust  shall  maintain  one or more bank
accounts in the name and for the sole benefit of the Trust;  provided,  however,
that all  payments of funds in respect of the  Debentures  held by the  Property
Trustee shall be made  directly to the Property  Account and no other funds from
the Trust shall be deposited in the Property  Account.  The sole signatories for
such accounts shall be designated by the Regular  Trustees;  provided,  however,
that the Property  Trustee shall designate the sole signatories for the Property
Account.

         SECTION  11.04.  Withholding.  The Trust and the Trustees  shall comply
with all withholding  requirements under United States federal,  state and local
law. The Trust shall request,  and the Holders shall provide to the Trust,  such
forms  or   certificates  as  are  necessary  to  establish  an  exemption  from
withholding with respect to each Holder,  and any  representations  and forms as
shall  reasonably  be  requested  by the Trust to assist it in  determining  the
extent of, and in fulfilling, its withholding obligations.  The Trust shall file
required  forms with  applicable  jurisdictions  and,  unless an exemption  from
withholding is properly  established by a Holder,  shall remit amounts  withheld
with respect to the Holder to applicable  jurisdictions.  To the extent that the
Trust is  required to withhold  and pay over any amounts to any  authority  with
respect to distributions or allocations to any Holder, the amount withheld shall
be deemed to be a distribution  in the amount of the  withholding to the Holder.
In the event of any  claimed  overwithholding,  Holders  shall be  limited to an
action against the applicable jurisdiction. If the amount to be withheld was not
withheld from a Distribution,  the Trust may reduce subsequent  Distributions by
the amount of such withholding.


                                   ARTICLE 12
                             AMENDMENTS AND MEETINGS

         SECTION  12.01.  Amendments.  (a) Except as otherwise  provided in this
Declaration or by any applicable  terms of the Securities,  this Declaration may
be amended by, and only by, a written  instrument  executed by a majority of the
Regular Trustees;  provided,  however, that (i) no amendment to this Declaration
shall be made  unless the  Regular  Trustees  shall have  obtained  (A) either a
ruling from the Internal  Revenue  Service or a written  unqualified  opinion of
nationally recognized independent tax counsel experienced in such matters





                                       47



to the effect that such  amendment will not cause the Trust to be classified for
United  States  federal  income  tax  purposes  as an  association  taxable as a
corporation  or a partnership  and to the effect that the Trust will continue to
be treated as a grantor  trust for  purposes  of United  States  federal  income
taxation  and  (B)  a  written  unqualified  opinion  of  nationally  recognized
independent  counsel  experienced  in  such  matters  to the  effect  that  such
amendment will not cause the Trust to be an Investment Company which is required
to be registered  under the Investment  Company Act, (ii) at such time after the
Trust has issued any Securities  which remain  outstanding,  any amendment which
would  adversely  affect the rights,  privileges or preferences of any Holder of
Securities may be effected only with such additional  requirements as may be set
forth in the terms of such Securities,  (iii) Section 4.02,  Section 9.01(c) and
this  Section  12.01  shall not be  amended  without  the  consent of all of the
Holders of the Securities, (iv) no amendment which adversely affects the rights,
powers and privileges of the Property  Trustee shall be made without the consent
of the Property Trustee,  (v) Article 4 shall not be amended without the consent
of the  Sponsor,  and (vi) the  rights of  Holders  of Common  Securities  under
Article 5 to  increase or  decrease  the number of, and to  appoint,  replace or
remove,  Trustees  shall not be amended  without  the  consent of each Holder of
Common Securities.

         (b)  Notwithstanding  Section  12.02(a)(ii),  this  Declaration  may be
amended  without the consent of the  Holders of the  Securities  to (i) cure any
ambiguity, (ii) correct or supplement any provision in this Declaration that may
be defective or inconsistent with any other provision of this Declaration, (iii)
to add to the covenants, restrictions or obligations of the Sponsor, and (iv) to
conform  to any  changes  in  Rule  3a-7  or any  change  in  interpretation  or
application of Rule 3a-7 by the  Commission,  which amendment does not adversely
affect the rights, preferences or privileges of the Holders.

         SECTION 12.02. Meetings of the Holders of Securities; Action by Written
Consent.  (a)  Meetings of the Holders of  Preferred  Securities  and/or  Common
Securities may be called at any time by the Regular  Trustees (or as provided in
the terms of the  Securities) to consider and act on any matter on which Holders
of such  class  of  Securities  are  entitled  to act  under  the  terms of this
Declaration,  the terms of the  Securities or the rules of any stock exchange on
which the Preferred  Securities are listed or admitted for trading.  The Regular
Trustees  shall  call a meeting of Holders  of  Preferred  Securities  or Common
Securities,  if  directed  to do so by  Holders  of at least 10% in  liquidation
amount of such class of Securities.  Such direction shall be given by delivering
to the Regular  Trustees one or more calls in a writing stating that the signing
Holders of  Securities  wish to call a meeting  and  indicating  the  general or
specific  purpose  for  which  the  meeting  is to be  called.  Any  Holders  of
Securities  calling a meeting shall specify in writing the Certificates  held by
the Holders of Securities  exercising the right to call a meeting and only those
specified  Certificates shall be counted for purposes of determining whether the
required  percentage set forth in the second sentence of this paragraph has been
met.




                                       48



         (b)  Except  to the  extent  otherwise  provided  in the  terms  of the
Securities,  the  following  provision  shall  apply to  meetings  of Holders of
Securities:

              (i) Notice of any such  meeting  shall be given by mail to all the
         Holders of  Securities  having a right to vote  thereat not less than 7
         days nor more than 60 days prior to the date of such meeting.  Whenever
         a vote,  consent or approval of the Holders of  Securities is permitted
         or required  under this  Declaration or the rules of any stock exchange
         on which the Preferred  Securities  are listed or admitted for trading,
         such vote, consent or approval may be given at a meeting of the Holders
         of Securities. Any action that may be taken at a meeting of the Holders
         of  Securities  may be taken  without a meeting if a consent in writing
         setting  forth the action so taken is signed by  Holders of  Securities
         owning  not less  than the  minimum  aggregate  liquidation  amount  of
         Securities  that would be necessary to authorize or take such action at
         a meeting  at which all  Holders of  Securities  having a right to vote
         thereon were present and voting.  Prompt notice of the taking of action
         without a meeting shall be given to the Holders of Securities  entitled
         to vote who have not  consented  in writing.  The Regular  Trustees may
         specify that any written ballot  submitted to the Holders of Securities
         for the  purpose  of taking  any  action  without  a  meeting  shall be
         returned  to the  Trust  within  the  time  specified  by  the  Regular
         Trustees.

              (ii) Each Holder of a Security may authorize any Person to act for
         it by proxy on all  matters in which a Holder of a Security is entitled
         to participate,  including waiving notice of any meeting,  or voting or
         participating  at  a  meeting.  No  proxy  shall  be  valid  after  the
         expiration of 11 months from the date thereof unless otherwise provided
         in the proxy.  Every proxy shall be  revocable  at the  pleasure of the
         Holder of the  Security  executing  it.  Except as  otherwise  provided
         herein or in the terms of the Securities,  all matters  relating to the
         giving,  voting or validity of proxies shall be governed by the General
         Corporation  Law of the State of  Delaware  relating  to  proxies,  and
         judicial  interpretations  thereunder,  as if the Trust were a Delaware
         corporation  and the Holders of the Securities  were  stockholders of a
         Delaware corporation.

              (iii) Each  meeting  of the  Holders  of the  Securities  shall be
         conducted  by the  Regular  Trustees  or by such other  Person that the
         Regular Trustees may designate.

              (iv) Unless  otherwise  provided in the Business  Trust Act,  this
         Declaration  or the rules of any stock  exchange on which the Preferred




                                       49



         Securities  are then  listed  or  admitted  for  trading,  the  Regular
         Trustees,   in  their  sole  discretion,   shall  establish  all  other
         provisions  relating to meetings  of Holders of  Securities,  including
         notice of the time, place or purpose of any meeting at which any matter
         is to be voted on by any  Holders  of  Securities,  waiver  of any such
         notice,  action by consent without a meeting,  the  establishment  of a
         record date, quorum  requirements,  voting in person or by proxy or any
         other matter with respect to the exercise of any such right to vote.

         other similar laws affecting creditors' rights generally and to general
         principles  of equity and the  discretion of the court  (regardless  of
         whether the  enforcement of such remedies is considered in a proceeding
         in equity or at law).

              (iii) The execution,  delivery and performance of this Declaration
         by the Property  Trustee does not conflict  with or constitute a breach

                                                                       EXHIBIT B



                                    TERMS OF
                              PREFERRED SECURITIES

         Pursuant to Section  7.01 of the Amended and  Restated  Declaration  of
Trust of AES Trust II dated as of  October  29,  1997 (as  amended  from time to
time, the "Declaration"),  the designations,  rights, privileges,  restrictions,
preferences  and other terms and provisions of the Preferred  Securities are set
forth  below  (each  capitalized  term used but not  defined  herein  having the
meaning set forth in the Declaration):

         1. DESIGNATION AND NUMBER.  Preferred  Securities of the Trust with  an
aggregate liquidation amount in the assets of the Trust of Three Hundred Million
Dollars  ($300,000,000)  (plus up to an additional  Forty-Five  Million  Dollars
($45,000,000)  issuable upon exercise of the  overallotment  option set forth in
the Purchase  Agreement) and a liquidation  amount in the assets of the Trust of
$50 per Preferred  Security,  are hereby  designated as "$2.75 Term  Convertible
Securities,  Series B".  The  Preferred  Security  Certificates  evidencing  the
Preferred Securities shall be substantially in the form attached hereto as Annex
I, with such  changes and  additions  thereto or  deletions  therefrom as may be
required by ordinary usage, custom or practice or to conform to the rules of any
stock exchange on which the Preferred  Securities are listed. In connection with
the issuance and sale of the Preferred Securities and the Common Securities, the
Trust will  purchase  as trust  assets  Debentures  of AES  having an  aggregate
principal  amount equal to the  aggregate  liquidation  amount of the  Preferred
Securities  and Common  Securities  so issued and bearing  interest at an annual
rate equal to the  annual  Distribution  rate on the  Preferred  Securities  and
Common Securities and having payment and redemption  provisions which correspond
to the payment and redemption  provisions of the Preferred Securities and Common
Securities.

         2. DISTRIBUTIONS.  (a) Distributions payable on each Preferred Security
will be fixed  at a rate per  annum of $2.75  (the  "Coupon  Rate")  subject  to
increase in certain limited  circumstances  pursuant to the Registration  Rights
Agreement per  Preferred  Security.  Distributions  in arrears for more than one
calendar  quarter will bear  interest at the rate per annum of 5.50% thereof (to
the extent permitted by law), compounded quarterly.  The term "Distributions" as
used herein means such periodic cash distributions and any such interest payable
unless  otherwise  stated.  A Distribution  will be made by the Property Trustee
only to the extent that interest  payments are made in respect of the Debentures
held by the Property Trustee. The amount of Distributions payable for any period
will be computed for any quarterly Distribution period on the basis of a 360-day
year of twelve 30-day months.








         (b) Distributions on the Preferred Securities will be cumulative,  will
accrue from October 29, 1997 and will be payable  quarterly  in arrears,  on the
last day of each quarter  commencing  on December 31, 1997,  except as otherwise
described below,  but only if and to the extent that interest  payments are made
in respect of the Debentures held by the Property Trustee.  So long as AES shall
not be in default in the  payment of  interest  on the  Debentures,  AES has the
right under the  Indenture for the  Debentures to defer  payments of interest by
extending the interest  payment period from time to time on the Debentures for a
period not  exceeding  20  consecutive  quarterly  interest  periods  (each,  an
"Extension Period") and, as a consequence, quarterly Distributions will continue
to accrue with interest  thereon (to the extent  permitted by applicable law) at
the rate of 5.50% per annum,  compounded  quarterly  during  any such  Extension
Period.  Prior to the termination of any such Extension Period,  AES may further
extend such Extension Period;  provided that such Extension Period together with
all such previous and further  extensions  thereof may not exceed 20 consecutive
quarterly  interest  periods;  and provided that no Extension  Period shall last
beyond the date of maturity or any redemption date of the Debentures..  Upon the
termination of any Extension Period and the payment of all amounts then due, AES
may commence a new Extension Period, subject to the above requirements. Payments
of accrued  Distributions will be payable to Holders of Preferred  Securities as
they appear on the books and records of the Trust on the first record date after
the end of the Extension Period.

         (c) Distributions on the Preferred  Securities will be payable promptly
by the  Property  Trustee (or other Paying  Agent) upon  receipt of  immediately
available  funds to the Holders  thereof as they appear on the books and records
of the Trust on the relevant record dates. While the Preferred Securities remain
in  book-entry  only form,  the relevant  record dates shall be one business day
prior to the relevant  Distribution date, and if the Preferred Securities are no
longer in book-entry  only form,  the Regular  Trustees  shall have the right to
select  relevant record dates which shall be more than one business day prior to
the relevant payment dates.  Distributions  payable on any Preferred  Securities
that are not punctually paid on any Distribution payment date as a result of AES
having failed to make the corresponding  interest payment on the Debentures will
forthwith  cease to be  payable  to the  person  in whose  name  such  Preferred
Security  is  registered  on  the  relevant  record  date,  and  such  defaulted
Distribution  will instead be payable to the person in whose name such Preferred
Security is registered  on the special  record date  established  by the Regular
Trustees, which record date shall correspond to the special record date or other
specified date determined in accordance with the Indenture;  provided,  however,
that Distributions  shall not be considered payable on any Distribution  payment
date falling within an Extension Period unless AES has elected to make a full or
partial  payment of  interest  accrued on the  Debentures  on such  Distribution
payment date.  Subject to any applicable laws and regulations and the provisions
of the Declaration,  each payment in respect of the Preferred Securities will be
made as described in paragraph 10




                                       2



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

         (d) All Distributions paid with respect to the Preferred Securities and
the Common  Securities  will be paid Pro Rata to the  Holders  thereof  entitled
thereto.  If an Event of Default has occurred and is  continuing,  the Preferred
Securities  shall have a priority  over the Common  Securities  with  respect to
Distributions.

         (e) In the event of an election by the Holder to convert its Securities
through  the  Conversion  Agent into Common  Stock  pursuant to the terms of the
Securities  as set  forth in this  Exhibit  B to the  Declaration,  no  payment,
allowance or  adjustment  shall be made with respect to  accumulated  and unpaid
Distributions on such Securities, or be required to be made; provided,  however,
that if a Security is surrendered for conversion  after the close of business on
any regular record date for payment of a Distribution  and before the opening of
business on the  corresponding  Distribution  date, then,  notwithstanding  such
conversion,  the Distribution  payable on such Distribution date will be paid in
cash to the  person in whose name the  Security  is  registered  at the close of
business  on such  record  date,  and (other  than a Security  or a portion of a
Security  called for redemption on a redemption date occurring after such record
date  and on or  prior  to  such  Distribution  date)  when so  surrendered  for
conversion,  the Security must be  accompanied  by payment of an amount equal to
the Distribution payable on such Distribution date.

         (f) In the event that there is any money or other  property  held by or
for the Trust that is not  accounted  for under the  Declaration,  such money or
property  shall be  distributed  Pro Rata  among the  Holders  of the  Preferred
Securities and Common Securities.

         3.  LIQUIDATION  DISTRIBUTION  UPON  DISSOLUTION.  In the  event of any
voluntary or  involuntary  dissolution,  winding-up or termination of the Trust,
the Holders of the Preferred Securities and Common Securities at the date of the
dissolution,  winding-up or termination, as the case may be, will be entitled to
receive  Pro  Rata  solely  out  of  the  assets  of  the  Trust  available  for
distribution  to Holders of Preferred  Securities  and Common  Securities  after
satisfaction  of liabilities  to creditors,  an amount equal to the aggregate of
the stated  liquidation amount of $50 per Preferred Security and Common Security
plus  accrued  and unpaid  Distributions  thereon  to the date of payment  (such
amount being the "Liquidation  Distribution"),  unless,  in connection with such
dissolution, winding-up or termination, and after




                                       3



satisfaction of liabilities to creditors,  Debentures in an aggregate  principal
amount  equal to the  aggregate  stated  liquidation  amount  of such  Preferred
Securities and Common  Securities and bearing  accrued and unpaid interest in an
amount  equal  to the  accrued  and  unpaid  Distributions  on,  such  Preferred
Securities and Common  Securities,  shall be distributed Pro Rata to the Holders
of  the  Preferred  Securities  and  Common  Securities  in  exchange  for  such
Securities.

         If, upon any such dissolution, the Liquidation Distribution can be paid
only in part because the Trust has insufficient  assets available to pay in full
the aggregate Liquidation Distribution, then the amounts payable directly by the
Trust on the Preferred  Securities and Common Securities shall be paid,  subject
to the next paragraph, on a Pro Rata basis.

         Holders of Common  Securities  will be entitled to receive  Liquidation
Distributions  upon any such  dissolution  Pro Rata with  Holders  of  Preferred
Securities,  except that if an Event of Default has occurred and is  continuing,
the Preferred  Securities shall have a priority over the Common  Securities with
respect to such Liquidation Distribution.

         4. REDEMPTION AND DISTRIBUTION OF DEBENTURES.  The Preferred Securities
and Common  Securities  may only be redeemed if  Debentures  having an aggregate
principal  amount equal to the  aggregate  liquidation  amount of the  Preferred
Securities  and Common  Securities  are repaid,  redeemed or  distributed as set
forth below:

         (a) Upon the repayment of the Debentures,  in whole or in part, whether
at  maturity,  upon  redemption  at any  time or from  time to time on or  after
September 30, 2000, or at any time in certain  circumstances upon the occurrence
of a Tax Event,  the  proceeds of such  repayment  will be  promptly  applied to
redeem Pro Rata Preferred  Securities and Common  Securities having an aggregate
liquidation amount equal to the aggregate  principal amount of the Debentures so
repaid or redeemed,  upon not less than 30 nor more than 60 days'  notice,  at a
redemption price per Preferred and Common Security equal to the redemption price
of the  Debentures,  together  with  accrued  and unpaid  Distributions  thereon
through the date of redemption,  payable in cash (the "Redemption  Price").  The
date of any such  repayment or  redemption  of Preferred  Securities  and Common
Securities  shall be  established  to coincide  with the repayment or redemption
date of the Debentures.

         (b) If fewer than all the outstanding  Preferred  Securities and Common
Securities  are to be so  redeemed,  the  Preferred  Securities  and the  Common
Securities will be redeemed Pro Rata and the Preferred Securities to be redeemed
will be  redeemed  as  described  in  paragraph  4(f)(ii)  below.  If a  partial
redemption  would result in the  delisting of the  Preferred  Securities  by any
national  securities  exchange  or other  organization  on which  the  Preferred
Securities are then listed, AES pursuant




                                       4



to the  Indenture  will only redeem  Debentures  in whole and, as a result,  the
Trust may only redeem the Preferred Securities in whole.

         (c) If, at any time, a Tax Event or an  Investment  Company Event (each
as  hereinafter  defined,  and  each  a  "Special  Event")  shall  occur  and be
continuing,  the Regular  Trustees shall,  unless the Debentures are redeemed in
the  limited  circumstances  described  below,  dissolve  the Trust  and,  after
satisfaction of creditors,  cause Debentures held by the Property Trustee having
an aggregate  principal amount equal to the aggregate stated  liquidation amount
of and accrued and unpaid interest equal to accrued and unpaid Distributions on,
and having the same  record  date for payment as the  Preferred  Securities  and
Common Securities,  to be distributed to the Holders of the Preferred Securities
and  Common  Securities  on a Pro Rata  basis in  liquidation  of such  Holders'
interests in the Trust,  within 90 days following the occurrence of such Special
Event  (the  "90  Day  Period"),  provided,  however,  that  in the  case of the
occurrence of a Tax Event, as a condition of such dissolution and  distribution,
the Regular  Trustees shall have received an opinion of a nationally  recognized
independent  tax  counsel   experienced  in  such  matters  (a  "No  Recognition
Opinion"),  which  opinion  may rely on any then  applicable  published  revenue
ruling of the Internal  Revenue  Service,  to the effect that the Holders of the
Preferred  Securities  will not  recognize  any gain or loss for  United  States
federal  income tax  purposes  as a result of the  dissolution  of the Trust and
distribution of Debentures;  and provided,  further,  that, if and as long as at
the time there is available to the Trust the  opportunity  to eliminate,  within
the 90 Day Period, the Special Event by taking some ministerial  action, such as
filing a form or making an election,  or pursuing some other similar  reasonable
measure  that has no  adverse  effect on the  Trust,  AES or the  Holders of the
Preferred Securities  ("Ministerial Action"), the Trust will pursue such measure
in lieu of dissolution.

         If in the  case of the  occurrence  of a Tax  Event,  (i)  the  Regular
Trustees  have  received an opinion (a  "Redemption  Tax Opinion") of nationally
recognized independent tax counsel experienced in such matters that, as a result
of a Tax  Event,  there is more  than an  insubstantial  risk  that AES would be
precluded  from  deducting  the  interest on the  Debentures  for United  States
federal  income tax purposes  even if the  Debentures  were  distributed  to the
Holders of Preferred  Securities  and Common  Securities in  liquidation of such
Holder's  interest in the Trust as described in this  paragraph 4(c) or (ii) the
Regular  Trustees  shall  have  been  informed  by such  tax  counsel  that a No
Recognition  Opinion cannot be delivered to the Trust,  AES shall have the right
at any time, upon not less than 30 nor more than 60 days' notice,  to redeem the
Debentures in whole or in part for cash at the  Redemption  Price within 90 days
following  the  occurrence  of such  Tax  Event,  and  promptly  following  such
redemption   Preferred  Securities  and  Common  Securities  with  an  aggregate
liquidation amount equal to the aggregate  principal amount of the Debentures so
redeemed  will be  redeemed by the Trust at the  Redemption  Price on a Pro Rata
basis; provided,




                                       5



however,  that, if at the time there is available to AES or the Regular Trustees
on behalf of the Trust the opportunity to eliminate,  within such 90 day period,
the Tax Event by taking some Ministerial  Action, AES or the Regular Trustees on
behalf  of the  Trust  will  pursue  such  measure  in lieu of  redemption  and;
provided,  further,  that AES shall have no right to redeem the Debentures while
the  Regular  Trustees  on behalf of the Trust  are  pursuing  such  Ministerial
Action.  The Common  Securities  will be  redeemed  Pro Rata with the  Preferred
Securities,  except that if an Event of Default under the Indenture has occurred
and is continuing, the Preferred Securities will have a priority over the Common
Securities with respect to payment of the Redemption Price.

         "Tax Event"  means that the  Regular  Trustees  shall have  obtained an
opinion of nationally  recognized  independent  tax counsel  experienced in such
matters (a "Dissolution Tax Opinion") to the effect that on or after October 23,
1997 as a result of (a) any  amendment  to, or change  (including  any announced
prospective  change) in, the laws (or any regulations  thereunder) of the United
States or any political  subdivision or taxing authority thereof or therein, (b)
any amendment to, or change in, an  interpretation  or  application  of any such
laws or regulations  by any  legislative  body,  court,  governmental  agency or
regulatory  authority  (including  the  enactment  of any  legislation  and  the
publication  of any  judicial  decision or  regulatory  determination),  (c) any
interpretation  or  pronouncement  that  provides for a position with respect to
such laws or regulations  that differs from the theretofore  generally  accepted
position  or (d) any  action  taken by any  governmental  agency  or  regulatory
authority,  which  amendment  or  change  is  enacted,  promulgated,  issued  or
announced or which  interpretation  or  pronouncement  is issued or announced or
which action is taken, in each case on or after October 23, 1997,  there is more
than an  insubstantial  risk that (i) the Trust is, or will be within 90 days of
the date thereof,  subject to United States  federal  income tax with respect to
income  accrued or  received  on the  Debentures,  (ii) the Trust is, or will be
within 90 days of the date thereof,  subject to more than a de minimis amount of
other taxes,  duties or other governmental  charges or (iii) interest payable by
AES to the Trust on the Debentures is not, or within 90 days of the date thereof
will not be, deductible by AES for United States federal income tax purposes.

         "Investment  Company Event" means that the Regular  Trustees shall have
received an opinion of nationally recognized  independent counsel experienced in
practice under the Investment Company Act that, as a result of the occurrence of
a change in law or regulation or a change in  interpretation  or  application of
law or  regulation  by any  legislative  body,  court,  governmental  agency  or
regulatory  authority  (a  "Change  in 1940 Act  Law"),  there  is more  than an
insubstantial risk that the Trust is or will be considered an Investment Company
which is required to be  registered  under the  Investment  Company  Act,  which
Change in 1940 Act Law becomes effective on or after October 23, 1997.




                                       6



         On the date fixed for any distribution of Debentures,  upon dissolution
of the  Trust,  (i) the  Preferred  Securities  will no  longer  be deemed to be
outstanding  and (ii)  certificates  representing  Preferred  Securities will be
deemed to represent  beneficial  interests in the Debentures having an aggregate
principal amount equal to the stated  liquidation amount of, and bearing accrued
and unpaid interest equal to accrued and unpaid Distributions on, such Preferred
Securities  until  such  certificates  are  presented  to AES or its  agent  for
transfer or reissuance.

         (d) The Trust  may not  redeem  any  outstanding  Preferred  Securities
unless all  accrued  and unpaid  Distributions  have been paid on all  Preferred
Securities for all quarterly Distribution periods terminating on or prior to the
date of redemption.

         (e)  If  Debentures  are   distributed  to  Holders  of  the  Preferred
Securities,  AES,  pursuant  to the  terms of the  Indenture,  will use its best
efforts to have the Debentures  listed on the New York Stock Exchange or on such
other exchange as the Preferred  Securities were listed immediately prior to the
distribution of the Debentures.

         (f) (i)  Notice of any  redemption  of, or  notice of  distribution  of
Debentures in exchange for, the Preferred  Securities  and Common  Securities (a
"Redemption/  Distribution  Notice")  will be given by the  Regular  Trustees on
behalf of the Trust by mail to each Holder of  Preferred  Securities  and Common
Securities  to be redeemed or  exchanged  not less than 30 nor more than 60 days
prior to the date fixed for redemption or exchange thereof.  For purposes of the
calculation of the date of redemption or exchange and the dates on which notices
are given pursuant to this paragraph  (f)(i), a  Redemption/Distribution  Notice
shall  be  deemed  to be  given  on the day  such  notice  is  first  mailed  by
first-class mail, postage prepaid, to Holders of Preferred Securities and Common
Securities.  Each  Redemption/Distribution  Notice  shall  be  addressed  to the
Holders of Preferred  Securities  and Common  Securities  at the address of each
such Holder  appearing  in the books and records of the Trust.  No defect in the
Redemption/Distribution  Notice or in the mailing of either thereof with respect
to  any  Holder  shall  affect  the  validity  of  the  redemption  or  exchange
proceedings with respect to any other Holder.

         (ii)  In the  event  that  fewer  than  all the  outstanding  Preferred
Securities are to be redeemed,  the Preferred  Securities to be redeemed will be
redeemed Pro Rata from each Holder of Preferred Securities,  it being understood
that, in respect of Preferred  Securities  registered in the name of and held of
record by DTC (or successor Clearing Agency) or any other nominee, the Preferred
Securities  will be redeemed from, and the  distribution of the proceeds of such
redemption will be made to, each Clearing Agency Participant (or person on whose
behalf such nominee holds such  securities)  in accordance  with the  procedures
applied by such agency or nominee.





                                       7



         (iii) Subject to paragraph 10 hereof,  if the Trust gives a Redemption/
Distribution  Notice in respect  of a  redemption  of  Preferred  Securities  as
provided in this paragraph 4 (which notice will be  irrevocable)  then (A) while
the  Preferred  Securities  are in  book-entry  only form,  with  respect to the
Preferred Securities, by 12:00 noon, New York City time, on the redemption date,
provided that AES has paid the Property Trustee, in immediately available funds,
a  sufficient  amount  of cash in  connection  with the  related  redemption  or
maturity of the Debentures,  the Property Trustee will deposit  irrevocably with
DTC (or  successor  Clearing  Agency)  funds  sufficient  to pay the  applicable
Redemption Price with respect to the Preferred  Securities and will give DTC (or
successor  Clearing  Agency)  irrevocable  instructions and authority to pay the
Redemption  Price to the  Holders  of the  Preferred  Securities  and (B) if the
Preferred  Securities  are  issued  in  definitive  form,  with  respect  to the
Preferred  Securities  and provided that AES has paid the Property  Trustee,  in
immediately  available funds, a sufficient amount of cash in connection with the
related redemption or maturity of the Debentures,  the Property Trustee will pay
the relevant  Redemption  Price to the Holders of such  Preferred  Securities by
check  mailed to the address of the relevant  Holder  appearing on the books and
records of the Trust on the redemption date. If a Redemption/Distribution Notice
shall have been given and funds  deposited  as  required,  if  applicable,  then
immediately  prior  to the  close  of  business  on the  date of  such  deposit,
Distributions  will  cease to  accrue on the  Preferred  Securities  called  for
redemption, such Preferred Securities will no longer be deemed to be outstanding
and all rights of Holders of such Preferred  Securities so called for redemption
will cease,  except the right of the  Holders of such  Preferred  Securities  to
receive the Redemption  Price,  but without  interest on such Redemption  Price.
Neither the  Trustees nor the Trust shall be required to register or cause to be
registered  the transfer of any Preferred  Securities  which have been so called
for redemption.  If any date fixed for redemption of Preferred Securities is not
a Business Day, then payment of the  Redemption  Price payable on such date will
be made on the next  succeeding  day that is a  Business  Day (and  without  any
interest or other  payment in respect of any such delay)  except  that,  if such
Business Day falls in the next calendar  year,  such payment will be made on the
immediately  preceding Business Day, in each case with the same force and effect
as if made on such date fixed for redemption.  If AES fails to repay  Debentures
on  maturity  or on the date  fixed for this  redemption  or if  payment  of the
Redemption  Price in respect of Preferred  Securities is improperly  withheld or
refused and not paid either by the  Property  Trustee or by AES  pursuant to the
Preferred Securities Guarantee,  Distributions on such Preferred Securities will
continue to accrue, from the original redemption date to the date of payment, in
which  case the  actual  payment  date  will be  considered  the date  fixed for
redemption for purposes of calculating the Redemption Price.

         (iv)  Redemption/Distribution  Notices  shall  be sent  by the  Regular
Trustees on behalf of the Trust to DTC or its nominee (or any successor Clearing
Agency or its




                                       8



nominee) if the Global Certificates have been issued or, if Definitive Preferred
Security  Certificates  have  been  issued,  to the  Holders  of  the  Preferred
Securities.

         (v) Upon the date of  dissolution  of the  Trust  and  distribution  of
Debentures as a result of the occurrence of a Special Event,  Preferred Security
Certificates shall be deemed to represent beneficial interests in the Debentures
so  distributed,   and  the  Preferred  Securities  will  no  longer  be  deemed
outstanding  and may be canceled  by the Regular  Trustees.  The  Debentures  so
distributed  shall have an aggregate  principal  amount  equal to the  aggregate
liquidation amount of the Preferred Securities so distributed.

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

         5. CONVERSION RIGHTS. The Holders of Securities shall have the right at
any time prior to the close of business on  September  30, 2012 (or, in the case
of  Securities  called for  redemption,  prior to the close of  business  on the
Business  Day  prior to the  redemption  date),  at their  option,  to cause the
Conversion  Agent to convert  Securities,  on behalf of the converting  Holders,
into shares of Common Stock in the manner described herein on and subject to the
following terms and conditions:

         The  Securities  will be  convertible  at the office of the  Conversion
Agent into fully paid and  nonassessable  shares of Common Stock pursuant to the
Holder's  direction to the  Conversion  Agent to exchange such  Securities for a
portion  of the  Debentures  theretofore  held by the  Trust on the basis of one
Security per $50 principal  amount of Debentures,  and immediately  convert such
amount of Debentures into fully paid and nonassessable shares of Common Stock at
an initial  rate of 0.8914  shares of Common Stock per $50  principal  amount of
Debentures  (which is  equivalent  to a conversion  price of $56.09 per share of
Common Stock, subject to certain adjustments set forth in Sections 5.03 and 5.04
of the Supplemental Indenture (as so adjusted, the "Conversion Price")).

         (a) In order to convert  Securities  into Common Stock the Holder shall
submit to the  Conversion  Agent at the office  referred to above an irrevocable
request  to  convert  Securities  on  behalf  of such  Holder  (the  "Conversion
Request"),  together,  if the Securities  are in  certificated  form,  with such
certificates.  The  Conversion  Request  shall  (i)  set  forth  the  number  of
Securities to be converted and the name or names,  if other than the Holder,  in
which the shares of Common Stock should be issued and (ii) direct the Conversion
Agent (a) to exchange such  Securities for a portion of the  Debentures  held by
the Trust (at the rate of exchange specified in the preceding paragraph) and (b)
to immediately convert such Debentures on behalf of





                                       9



such  Holder,  into  Common  Stock  (at the  conversion  rate  specified  in the
preceding paragraph).  The Conversion Agent shall notify the Property Trustee of
the Holder's  election to exchange  Securities  for a portion of the  Debentures
held by the Trust and the Property  Trustee shall,  upon receipt of such notice,
deliver to the Conversion  Agent the appropriate  principal amount of Debentures
for  exchange  in  accordance  with this  Section.  The  Conversion  Agent shall
thereupon notify the Property  Trustee of the Holder's  election to convert such
Debentures  into  shares of Common  Stock.  If a  Security  is  surrendered  for
conversion after the close of business on any regular record date for payment of
a  Distribution  and  before  the  opening  of  business  on  the  corresponding
Distribution   payment  date,  then,   notwithstanding   such  conversion,   the
Distribution  payable on such Distribution  payment date will be paid in cash to
the person in whose name the Security is  registered at the close of business on
such record date,  and (other than a Security or a portion of a Security  called
for redemption on a redemption  date occurring  after such record date and on or
prior to such Distribution payment date) when so surrendered for conversion, the
Security must be accompanied  by payment of an amount equal to the  Distribution
payable on such Distribution payment date. Except as provided above, neither the
Trust nor the Sponsor will make, or be required to make, any payment,  allowance
or  adjustment  upon any  conversion  on account of any  accumulated  and unpaid
Distributions  accumulated on the Securities  surrendered for conversion,  or on
account of any  accumulated  and unpaid  dividends on the shares of Common Stock
issued upon such  conversion.  Securities shall be deemed to have been converted
immediately  prior to the close of business  on the day on which the  Conversion
Request  relating to such Securities is received by the Trust in accordance with
the foregoing  provision (the "Conversion Date"). The Person or Persons entitled
to receive  Common Stock  issuable upon  conversion of the  Debentures  shall be
treated for all purposes as the record holder or holders of such Common Stock at
such time.  As promptly as  practicable  on or after the  Conversion  Date,  the
Sponsor  shall  issue  and  deliver  at the  office  of the  Conversion  Agent a
certificate  or  certificates  for the  number of full  shares  of Common  Stock
issuable upon such conversion,  together with the cash payment,  if any, in lieu
of any  fraction  of any share to the Person or Persons  entitled to receive the
same, unless otherwise  directed by the Holder in the Conversion Request and the
Conversion Agent shall  distribute such  certificate or  certificates,  together
with the applicable cash payment, if any, to such Person or Persons.

         (b) Each Holder of a Security by his  acceptance  thereof  appoints The
First National Bank of Chicago  "Conversion  Agent" for the purpose of effecting
the conversion of Securities in accordance  with this Section.  In effecting the
conversion and  transactions  described in this Section,  the  Conversion  Agent
shall be acting as agent of the  Holders of  Securities  directing  it to effect
such conversion  transactions.  The Conversion Agent is hereby authorized (i) to
exchange  Securities  from  time to time  for  Debentures  held by the  Trust in
connection  with the  conversion  of such  Securities  in  accordance  with this
section and (ii) to convert all or a portion of the





                                       10



Debentures  into Common  Stock and  thereupon  to deliver  such shares of Common
Stock in  accordance  with the  provisions of this section and to deliver to the
Trust a new Debenture or  Debentures  for any  resulting  unconverted  principal
amount.

         (c) No fractional  shares of Common Stock will be issued as a result of
conversion,  but in lieu thereof,  such fractional interest will be paid in cash
by the Sponsor to the Conversion Agent,  which in turn will make such payment to
the Holder or Holders of Securities so converted.

         (d) The Sponsor  shall at all times  reserve and keep  available out of
its  authorized  and  unissued  Common  Stock,  solely  for  issuance  upon  the
conversion of the Debentures,  free from any preemptive or other similar rights,
such  number of shares of Common  Stock as shall  from time to time be  issuable
upon the conversion of all the Debentures then outstanding.  Notwithstanding the
foregoing,  the  Sponsor  shall  be  entitled  to  deliver  upon  conversion  of
Debentures,  shares of Common Stock  reacquired  and held in the treasury of the
Sponsor (in lieu of the issuance of  authorized  and  unissued  shares of Common
Stock),  so long as any such  treasury  shares  are free and clear of all liens,
charges,  security interests or encumbrances.  Any shares of Common Stock issued
upon conversion of the Debentures shall be duly  authorized,  validly issued and
fully paid and nonassessable. The Trust shall deliver the shares of Common Stock
received upon  conversion of the  Debentures to the  converting  Holder free and
clear of all liens,  charges,  security  interests and encumbrances,  except for
United States withholding taxes. Each of the Sponsor and the Trust shall prepare
and shall use its best efforts to obtain and keep in force such  governmental or
regulatory permits or other  authorizations as may be required by law, and shall
comply with all applicable  requirements as to registration or  qualification of
Common Stock (and all requirements to list Common Stock issuable upon conversion
of Debentures that are at the time  applicable),  in order to enable the Sponsor
to lawfully  issue Common Stock to the Trust upon  conversion of the  Debentures
and the Trust to lawfully deliver Common Stock to each Holder upon conversion of
the Securities.

         (e) The  Sponsor  will pay any and all  taxes  that may be  payable  in
respect of the issue or  delivery  of shares of Common  Stock on  conversion  of
Debentures  and the  delivery  of the  shares of Common  Stock by the Trust upon
conversion of the Securities. The Sponsor shall not, however, be required to pay
any tax which may be payable in respect of any  transfer  involved  in the issue
and  delivery  of shares of Common  Stock in a name other than that in which the
Securities so converted were registered,  and no such issue or delivery shall be
made unless and until the person requesting such issue has paid to the Trust the
amount of any such tax, or has established to the satisfaction of the Trust that
such tax has been paid.



                                       11



         (f) Nothing in the preceding  Paragraph (e) shall limit the requirement
of the Trust to withhold  taxes  pursuant to the terms of the  Securities as set
forth in this  Exhibit  B to the  Declaration  or to the  Declaration  itself or
otherwise  require  the  Property  Trustee  or the Trust to pay any  amounts  on
account of such withholdings.

         6. VOTING RIGHTS. (a) Except as provided under paragraph 6(b) below and
as otherwise  required by law and the Declaration,  the Holders of the Preferred
Securities will have no voting rights.

         (b) If any proposed  amendment to the Declaration  provides for, or the
Regular  Trustees  otherwise  propose  to  effect,  (i) any  action  that  would
adversely  affect the powers,  preferences or special rights of the  Securities,
whether  by way of  amendment  to the  Declaration  or  otherwise,  or (ii)  the
dissolution,  winding-up or termination  of the Trust,  other than in connection
with the  distribution  of  Debentures  held by the Property  Trustee,  upon the
occurrence of a Special Event or in connection  with the redemption of Preferred
Securities as a consequence of a redemption of  Debentures,  then the Holders of
outstanding Securities will be entitled to vote on such amendment or proposal as
a class and such  amendment or proposal  shall not be effective  except with the
approval of the Holders of  Securities  representing  a Majority in  liquidation
amount of such  Securities;  provided,  however,  that (A) if any  amendment  or
proposal  referred  to in  clause  (i) above  would  adversely  affect  only the
Preferred Securities or the Common Securities, then only the affected class will
be entitled to vote on such amendment or proposal and such amendment or proposal
shall not be  effective  except with the  approval of a Majority in  liquidation
amount of such class of Securities and (B) amendments to the  Declaration  shall
be subject to such further  requirements  as are set forth in Sections 12.01 and
12.02 of the Declaration.

         In the event the consent of the Property Trustee,  as the holder of the
Debentures,  is required  under the  Indenture  with  respect to any  amendment,
modification  or  termination of the Indenture or the  Debentures,  the Property
Trustee  shall  request the written  direction of the Holders of the  Securities
with  respect to such  amendment,  modification  or  termination.  The  Property
Trustee shall vote with respect to such  amendment,  modification or termination
as  directed  by a  Majority  in  liquidation  amount of the  Securities  voting
together as a single class; provided that where such amendment,  modification or
termination  of the  Indenture  requires  the  consent or vote of (1) holders of
Debentures  representing  a  specified  percentage  greater  than a majority  in
principal  amount  of the  Debentures  or (2) each  holder  of  Debentures,  the
Property  Trustee may only vote with respect to that amendment,  modification or
termination as directed by, in the case of clause (1) above, the vote of Holders
of  Securities   representing   such  specified   percentage  of  the  aggregate
liquidation amount of the Securities,  or, in the case of clause (2) above, each
Holder of Securities; and provided,  further, that the Property Trustee shall be
under no obligation to take any action in accordance  with the directions of the
Holders of




                                       12



Securities  unless the Property  Trustee shall have received,  at the expense of
the  Sponsor,  an opinion  of  nationally  recognized  independent  tax  counsel
recognized  as expert in such  matters to the effect  that the Trust will not be
classified  for United  States  federal  income tax  purposes as an  association
taxable as a corporation  or a partnership on account of such action and will be
treated  as a grantor  trust for  United  States  federal  income  tax  purposes
following such action.

         Subject to Section 2.06 of the Declaration,  and the provisions of this
and the next  succeeding  paragraph,  the Holders of a Majority  in  liquidation
amount of the Preferred Securities,  voting separately as a class shall have the
right to (A) on behalf of all Holders of  Preferred  Securities,  waive any past
default that is waivable  under the  Declaration  (subject to, and in accordance
with the  Declaration)  and (B) direct the time,  method and place of conducting
any proceeding for any remedy available to the Property  Trustee,  or exercising
any trust or power  conferred upon the Property  Trustee under the  Declaration,
including  the  right to  direct  the  Property  Trustee,  as the  holder of the
Debentures,  to (i)  direct  the  time,  method  and  place  of  conducting  any
proceeding for any remedy available to the Debenture Trustee,  or exercising any
trust  or  power  conferred  on  the  Debenture  Trustee  with  respect  to  the
Debentures,  (ii) waive any past default that is waivable  under Section 6.06 of
the  Indenture,  or (iii)  exercise any right to rescind or annul a  declaration
that the principal of all the Debentures shall be due and payable; provided that
where the taking of any action under the Indenture  requires the consent or vote
of (1) holders of Debentures  representing a specified percentage greater than a
majority in principal amount of the Debentures or (2) each holder of Debentures,
the  Property  Trustee may only take such action if directed  by, in the case of
clause (1) above, the vote of Holders of Preferred Securities  representing such
specified  percentage  of the  aggregate  liquidation  amount  of the  Preferred
Securities,  or, in the case of  clause  (2)  above,  each  Holder of  Preferred
Securities.  The  Property  Trustee  shall  not  revoke  any  action  previously
authorized  or approved by a vote of the  Holders of the  Preferred  Securities.
Other than with respect to directing  the time,  method and place of  conducting
any proceeding for any remedy available to the Property Trustee or the Debenture
Trustee as set forth above, the Property Trustee shall be under no obligation to
take any of the  foregoing  actions at the direction of the Holders of Preferred
Securities  unless the Property  Trustee shall have received,  at the expense of
the  Sponsor,  an opinion  of  nationally  recognized  independent  tax  counsel
recognized  as expert in such  matters to the effect  that the Trust will not be
classified  for United  States  federal  income tax  purposes as an  association
taxable as a corporation  or a partnership on account of such action and will be
treated  as a grantor  trust for  United  States  federal  income  tax  purposes
following such action. If the Property Trustee fails to enforce its rights under
the  Declaration  (including,   without  limitation,   its  rights,  powers  and
privileges as a holder of the  Debentures  under the  Indenture),  any Holder of
Preferred  Securities may, to the extent  permitted by law, after a period of 30
days has elapsed from such Holder's  written request to the Property  Trustee to
enforce such rights, institute a




                                       13


legal proceeding  directly against AES to enforce the Property  Trustee's rights
under the Declaration,  without first instituting a legal proceeding against the
Property Trustee or any other Person. Notwithstanding the foregoing, if an Event
of Default has occurred and is continuing and such event is  attributable to the
failure of the Sponsor 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 the registered holder of the Preferred
Securities  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
Sponsor will be subrogated to the rights of such Holder of Preferred  Securities
under the  Declaration  to the extent of any payment made by the Sponsor to such
Holder of Preferred Securities in such Holder Direct Action.  Except as provided
in the preceding sentences, the holders of Preferred Securities will not be able
to exercise any other remedy available to the holders of the Debentures.

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

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

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

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






                                       14



         Except as  provided  in this  paragraph  6,  Holders  of the  Preferred
Securities will have no rights to increase or decrease the number of Trustees or
to appoint,  remove or replace a Trustee,  which voting rights are vested solely
in the Holders of the Common Securities.

         7. PRO RATA  TREATMENT.  A reference  in these  terms of the  Preferred
Securities to any payment,  distribution  or treatment as being "Pro Rata" shall
mean  pro  rata  to  each  Holder  of  Securities  according  to  the  aggregate
liquidation  amount of the Securities held by the relevant Holder in relation to
the  aggregate  liquidation  amount of all  Securities  outstanding  unless,  in
relation to a payment,  an Event of Default has occurred and is  continuing,  in
which case any funds  available to make such payment shall be paid first to each
Holder  of  the  Preferred  Securities  pro  rata  according  to  the  aggregate
liquidation amount of Preferred  Securities held by the relevant Holder relative
to the aggregate liquidation amount of all Preferred Securities outstanding, and
only after  satisfaction  of all amounts  owed to the  Holders of the  Preferred
Securities,  to each  Holder  of Common  Securities  pro rata  according  to the
aggregate  liquidation  amount of Common  Securities held by the relevant Holder
relative  to  the  aggregate   liquidation   amount  of  all  Common  Securities
outstanding.

         8.  RANKING.  The  Preferred  Securities  rank pari  passu and  payment
thereon  will be made Pro Rata with the Common  Securities  except that where an
Event of Default  occurs and is  continuing,  the rights of Holders of Preferred
Securities to payment in respect of Distributions and payments upon liquidation,
redemption or otherwise  rank in priority to the rights of Holders of the Common
Securities.

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

         10. TRANSFER,  EXCHANGE,  METHOD OF PAYMENTS.  Payment of Distributions
and payments on  redemption  of the Preferred  Securities  will be payable,  the
transfer  of  the  Preferred  Securities  will  be  registrable,  and  Preferred
Securities will be exchangeable for Preferred  Securities of other denominations
of a like aggregate  liquidation amount, at the principal corporate trust office
of the  Property  Trustee  in The City of New York;  provided  that  payment  of
Distributions may be made at the option of the Regular Trustees on behalf of the
Trust by check  mailed to the address of the persons  entitled  thereto and that
the  payment on  redemption  of any  Preferred  Security  will be made only upon
surrender of such Preferred Security to the Property Trustee.

         11.  ACCEPTANCE OF INDENTURE AND  PREFERRED  GUARANTEE.  Each Holder of
Preferred Securities, by the acceptance thereof, agrees to the provisions of (i)
the Preferred Guarantee, including the subordination provisions therein and (ii)
the




                                       15


Indenture  and the  Debentures,  including the  subordination  provisions of the
Indenture.

         12. NO PREEMPTIVE  RIGHTS.  The Holders of Preferred  Securities  shall
have no preemptive rights to subscribe to any additional Preferred Securities or
Common Securities.

         13.  MISCELLANEOUS.   These  terms  shall  constitute  a  part  of  the
Declaration.  The Trust will provide a copy of the Declaration and the Indenture
to a Holder  without  charge on written  request  to the Trust at its  principal
place of business.

Preferred Security is a Global Certificate within the meaning of the Declaration
hereinafter  referred to and is registered in the name of The  Depository  Trust

         AES Trust II, a statutory  business trust created under the laws of the

is the registered  owner of  ___________  (______)  preferred  securities of the
Trust  representing  undivided  beneficial  interests in the assets of the Trust
designated the $2.75 Term Convertible  Securities,  Series B (liquidation amount
$50 per security) (the  "Preferred  Securities").  The Preferred  Securities are
transferable  on the  books and  records  of the  Trust,  in person or by a duly
authorized  attorney,  upon surrender of this  certificate  duly endorsed and in
proper form for transfer. The designations,  rights,  privileges,  restrictions,
preferences  and other terms and provisions of the Preferred  Securities are set
forth in, and this certificate and the Preferred  Securities  represented hereby
are issued and shall in all respects be subject to the terms and  provisions of,
the Amended and Restated  Declaration  of Trust of the Trust dated as of October
29,  1997,  as the same may be  amended  from time to time  (the  "Declaration")
including the  designation of the terms of Preferred  Securities as set forth in
Exhibit B thereto.  The Preferred Securities and the Common Securities issued by
the Trust pursuant to the Declaration  represent undivided  beneficial interests
in the  assets  of the  Trust,  including  the  Debentures  (as  defined  in the
Declaration) issued by The AES Corporation,  a Delaware  corporation ("AES"), to
the Trust pursuant to the Indenture  referred to in the Declaration.  The Holder
is  entitled  to the  benefits  of the  Guarantee  Agreement  of AES dated as of
October 29, 1997 (the  "Guarantee")  to the extent provided  therein.  The Trust
will furnish a copy of the  Declaration,  the Guarantee and the Indenture to the
Holder without charge upon written  request to the Trust at its principal  place
of business or registered office.

         The Holder of this  Certificate,  by  accepting  this  Certificate,  is
deemed  to have (i)  agreed to the terms of the  Indenture  and the  Debentures,
including that the Debentures are  subordinate and junior in right of payment to
all Senior and  Subordinated  Debt (as defined in the  Indenture)  as and to the
extent  provided in the Indenture and (ii) agreed to the terms of the Guarantee,
including  that the Guarantee is  subordinate  and junior in right of payment to
all other liabilities of AES, including the Debentures,  and ranks pari passu in
right payment with the most senior preferred stock issued, from time to time, by
AES.

         Upon  receipt  of  this  certificate,   the  Holder  is  bound  by  the
Declaration and is entitled to the benefits thereunder.

         Unless the Property Trustee's  Certificate of Authentication hereon has
been properly executed,  these Trust Preferred  Securities shall not be entitled
to any benefit under the Declaration or be valid or obligatory for any purpose.

                          [FORM OF REVERSE OF SECURITY]

         Distributions  payable on each  Preferred  Security  will be fixed at a
rate per  annum of $2.75 per  Preferred  Security,  such rate  being the rate of
interest  payable  on  the  Debentures  to be  held  by  the  Property  Trustee.
Distributions in arrears for more than one quarter will bear interest thereon at
the rate per annum of 5.50% thereof (to the extent  permitted by law) compounded
quarterly. The term "Distributions" as used herein means such cash distributions
and any such interest payable unless otherwise stated. A Distribution is payable
only to the extent that payments are made in respect of the  Debentures  held by
the Property Trustee. The amount of Distributions payable for any period will be
computed on the basis of a 360-day year of twelve 30-day months.

         Except as otherwise  described  below,  distributions  on the Preferred
Securities  will be  cumulative,  will accrue from  October 29, 1997 and will be
payable  quarterly in arrears,  on the last day of each  quarter,  commencing on
December 31, 1997, but only if and to the extent that interest payments are made
in respect of the Debentures held by the Property Trustee.  So long as AES shall
not be in default in the  payment of  interest  on the  Debentures,  AES has the
right under the  Indenture for the  Debentures to defer  payments of interest by
extending the interest  payment period from time to time on the Debentures for a
period not exceeding 20 consecutive  quarters (each an "Extension  Period") and,
as a consequence,  quarterly Distributions will continue to accrue with interest
thereon (to the extent  permitted  by  applicable  law) at the rate of 5.50% per
annum,  compounded  quarterly  during such  Extension  period;  provided that no
Extension  Period shall last beyond the date of maturity or any redemption  date
of the Debentures.  Prior to the termination of any such Extension  Period,  AES
may  commence  a new  Extension  Period;  provided  that such  Extension  Period
together with all such previous and further extensions thereof may not exceed 20
consecutive  quarterly interest periods.  Payments of accrued Distributions will
be payable to  Holders as they  appear on the books and  records of the Trust on
the  first  record  date  after  the  end  of the  Extension  Period.  Upon  the
termination of any Extension Period and the payment of all amounts then due, AES
may commence a new Extension Period, subject to the above requirements.

         The  Preferred  Securities  shall  be  redeemable  as  provided  in the
Declaration.

         The Preferred  Securities  shall be  convertible  into shares of Common
Stock,  through (i) the  exchange of Preferred  Securities  for a portion of the
Debentures  and (ii) the  immediate  conversion of such  Debentures  into Common
Stock, in the manner and according to the terms set forth in the Declaration.

rate  specified  in the terms of the  Trust  Preferred  Securities  set forth as
Exhibit B to the Declaration).

         The undersigned  does also hereby direct the Conversion  Agent that the

         3.   We  understand  that  the  offer  and the  sale  of the  Preferred
              Securities has not been  registered  under the Securities Act, and
              that the Preferred Securities may not be offered or sold except as
              permitted in the following  sentence.  We agree, on our own behalf
              and  on  behalf  of any  accounts  for  which  we  are  acting  as
              hereinafter   stated,   that  if  we  should  sell  any  Preferred
              Securities or, if applicable,  the Junior Subordinated  Debentures
              or Common  Stock  (together,  the  "Securities")  within two years
              after the original issuance of the Preferred  Securities,  we will
              do so  only  (A) to The AES  Corporation  (the  "Company")  or any
              subsidiary  thereof,  (B) inside the United  States in  accordance
              with  Rule  144A  under  the   Securities   Act  to  a  "qualified
              institutional buyer" (as defined therein), (C) inside the



                                       14



              United  States  to  an  institutional  "accredited  investor"  (as
              defined  below)  that,  prior to such  transfer,  furnishes to the
              Trustee a signed letter  containing  certain  representations  and
              agreements  relating  to  the  restrictions  on  transfer  of  the
              Preferred  Securities  (the form of which  letter can be  obtained
              from the Trustee) and, if such transfer is in respect of Preferred
              Securities with an aggregate  liquidation  preference of less than
              $250,000,  an opinion of counsel  acceptable  to the Company  that
              such  transfer  is in  compliance  with the  Securities  Act,  (D)
              outside the United  States in  accordance  with the Rule 904 under
              the Securities Act (E) pursuant to the exemption from registration
              provided by Rule 144 under the  Securities  Act (if  available) or
              (F)  pursuant to an  effective  registration  statement  under the
              Securities  Act,  and we  further  agree to  provide to any person
              purchasing  any of  the  Preferred  Securities  from  us a  notice
              advising such purchaser  that resales of the Preferred  Securities
              are restricted as stated herein.

         4.   We understand  that, on any proposed resale of any Securities,  we
              will be  required  to furnish to the Issuer and the  Trustee  such
              certifications, legal opinions and other information as the Issuer
              and the  Trustee  may  reasonably  require  to  confirm  that  the
              proposed sale complies with the foregoing restrictions. We further
              understand that the Securities  purchased by us will bear a legend
              to the foregoing effect.

         5.   We are a institutional  "accredited  investor" (as defined in rule
              501(a)(1),  (2), (3) or (7) of  Regulation D under the  Securities
              Act) and have such  knowledge  and  experience  in  financial  and
              business  matters as to be capable  of  evaluating  the merits and
              risks of our  investment in the Preferred  Securities,  and we and
              any  accounts  for which we are  acting  are each able to bear the
              economic risks of our or their investment.

         6.   We are acquiring the Preferred  Securities purchased by us for our
              own  account  for  one or  more  accounts  (each  of  which  is an
              institutional  "accredited  investor")  as to  each  of  which  we
              exercise sole investment discretion.



                                       15



         You.  the Issuer and the Trustee are  entitled to rely upon this letter
and are  irrevocably  authorized  to produce this letter or a copy hereof to any
interested party in any  administrative or legal proceedings or official inquiry
with respect to the matters covered hereby.



                                           Very truly yours,


                                           By:
                                               ---------------------------------
                                                 Name:
                                                 Title:





                                       16



                                                                       EXHIBIT C


                                    TERMS OF
                                COMMON SECURITIES


         Pursuant to Section  7.01 of the Amended and  Restated  Declaration  of
Trust of AES Capital Trust II dated as of October 29, 1997 (as amended from time
to time, the "Declaration"), the designations, rights, privileges, restrictions,
preferences  and other terms and  provisions  of the Common  Securities  are set
forth  below  (each  capitalized  term used but not  defined  herein  having the
meaning set forth in the Declaration):

         1.  DESIGNATION  AND  NUMBER.  Common  Securities  of the Trust with an
aggregate  liquidation  amount in the  assets of the Trust of Nine  Million  Two
Hundred Seventy-Eight  Thousand Three Hundred Fifty Dollars ($9,278,400 (plus up
to an additional  One Million Three Hundred  Ninety-One  Thousand  Seven Hundred
Fifty Dollars  ($1,391,800)  issuable upon exercise of the overallotment  option
set forth in the Purchase  Agreement) and a liquidation  amount in the assets of
the Trust of $50 per Common  Security,  are hereby  designated  as "$2.75 Common
Trust  Securities".  The  Common  Security  Certificates  evidencing  the Common
Securities  shall be  substantially in the form attached hereto as Annex I, with
such changes and additions thereto or deletions  therefrom as may be required by
ordinary usage,  custom or practice.  The Common Securities are to be issued and
sold to The AES Corporation  ("AES") in  consideration of $9,278,400 in cash. In
connection with the issuance and sale of the Preferred Securities and the Common
Securities,  the Trust will purchase as trust assets Debentures of AES having an
aggregate  principal  amount equal to the  aggregate  liquidation  amount of the
Preferred Securities and Common Securities so issued, and bearing interest at an
annual rate equal to the annual  Distribution  rate on the Preferred  Securities
and Common  Securities  and  having  payment  and  redemption  provisions  which
correspond to the payment and redemption  provisions of the Preferred Securities
and Common Securities.

         2.  DISTRIBUTIONS.  (a)  Distributions  payable on each Common Security
will be fixed  at a rate per  annum of $2.75  (the  "Coupon  Rate")  per  Common
Security.  Distributions in arrears for more than one calendar quarter will bear
interest  at the rate per annum of 5.50%  thereof  (to the extent  permitted  by
applicable law), compounded quarterly. The term "Distributions" as used in these
terms means such  periodic  cash  distributions  and any such  interest  payable
unless  otherwise  stated.  A Distribution  will be made by the Property Trustee
only to the extent that interest  payments are made in respect of the Debentures
held by the Property Trustee. The amount of





                                       



Distributions   payable  for  any  period  will  be  computed  for  any  monthly
Distribution period on the basis of a 360-day year of twelve 30 day months.

         (b)  Distributions  on the Common  Securities will be cumulative,  will
accrue from October 29, 1997 and will be payable  quarterly  in arrears,  on the
last day of each month  commencing  on December  31,  1997,  except as otherwise
described below,  but only if and to the extent that interest  payments are made
in respect of the Debentures held by the Property Trustee.  So long as AES shall
not be in default in the  payment of  interest  on the  Debentures,  AES has the
right under the  Indenture for the  Debentures to defer  payments of interest by
extending the interest  payment period from time to time on the Debentures for a
period not  exceeding  20  consecutive  quarterly  interest  periods  (each,  an
"Extension Period") and, as a consequence, quarterly Distributions will continue
to accrue with interest  thereon (to the extent  permitted by applicable law) at
the rate of 5.50% per annum,  compounded  quarterly  during  any such  Extension
Period; provided that no Extension Period shall last beyond the date of maturity
or any redemption date of the  Debentures.  Prior to the termination of any such
Extension Period,  AES may further extend such Extension  Period;  provided that
such  Extension  Period  together with all such previous and further  extensions
thereof  may not exceed 20  consecutive  quarterly  interest  periods.  Upon the
termination of any Extension Period and the payment of all amounts then due, AES
may commence a new Extension Period, subject to the above requirements. Payments
of accrued Distributions will be payable to Holders of Common Securities as they
appear on the books and records of the Trust on the first  record date after the
end of the Extension Period.

         (c)  Distributions on the Common Securities will be payable promptly by
the  Property  Trustee  (or other  Paying  Agent)  upon  receipt of  immediately
available  funds to the Holders  thereof as they appear on the books and records
of the Trust on the  relevant  record dates which will be one business day prior
to the relevant  Distribution date unless the Preferred Securities are no longer
in book-entry only form in which event the Regular Trustees shall have the right
to select  relevant record dates which shall be more than one business day prior
to the relevant payment dates.  Distributions  payable on any Common  Securities
that are not punctually paid on any Distribution  date as a result of AES having
failed  to make  the  corresponding  interest  payment  on the  Debentures  will
forthwith  cease to be payable to the person in whose name such Common  Security
is registered on the relevant record date, and such defaulted  Distribution will
instead  be  payable  to the  person  in whose  name  such  Common  Security  is
registered on the special record date established by the Regular Trustees, which
record date shall  correspond to the special record date or other specified date
determined  in  accordance   with  the  Indenture;   provided,   however,   that
Distributions  shall not be considered payable on any Distribution  payment date
falling  within an  Extension  Period  unless AES has  elected to make a full or
partial  payment of  interest  accrued on the  Debentures  on such  Distribution
payment date. Subject to any





                                       2



applicable  laws and  regulations  and the provisions of the  Declaration,  each
payment  in  respect  of the  Common  Securities  will be made as  described  in
paragraph  10  hereof.  If any date on which  Distributions  are  payable on the
Common  Securities  is not a Business  Day,  then  payment  of the  Distribution
payable on such date will be made on the next  succeeding day that is a Business
Day (and  without any  interest  or other  payment in respect of any such delay)
except that, if such Business Day is in the next succeeding  calendar year, such
payment shall be made on the  immediately  preceding  Business Day, in each case
with the same force and effect as if made on such date.

         (d) All  Distributions  paid with respect to the Common  Securities and
the Preferred  Securities will be paid Pro Rata to the Holders thereof  entitled
thereto.  If an Event of Default has occurred and is  continuing,  the Preferred
Securities  shall have a priority  over the Common  Securities  with  respect to
Distributions.

         (e) In the event of an election by the Holder to convert its Securities
through  the  Conversion  Agent into Common  Stock  pursuant to the terms of the
Securities  as set  forth in this  Exhibit  C to the  Declaration,  no  payment,
allowance or  adjustment  shall be made with respect to  accumulated  and unpaid
Distributions on such Securities, or be required to be made; provided,  however,
that if a Security is surrendered for conversion  after the close of business on
any regular record date for payment of a Distribution  date will be paid in cash
to the person in whose name the Security is  registered at the close of business
on such  record  date,  and (other  than a  Security  or a portion of a Security
called for redemption on a redemption  date occurring after such record date and
on or prior to such Distribution  date) when so surrendered for conversion,  the
Security must be accompanied  by payment of an amount equal to the  Distribution
payable on such Distribution date.

         (f) In the event that there is any money or other  property  held by or
for the Trust that is not  accounted  for under the  Declaration,  such money or
property  shall be  distributed  Pro Rata  among the  Holders  of the  Preferred
Securities and Common Securities.

         3.  LIQUIDATION  DISTRIBUTION  UPON  DISSOLUTION.  In the  event of any
voluntary or  involuntary  dissolution,  winding-up or termination of the Trust,
the Holders of the Preferred Securities and Common Securities at the date of the
dissolution,  winding-up or termination, as the case may be, will be entitled to
receive  Pro  Rata  solely  out  of  the  assets  of  the  Trust  available  for
distribution  to Holders of Preferred  Securities and Common  Securities,  after
satisfaction  of liabilities  to creditors,  an amount equal to the aggregate of
the stated  liquidation amount of $50 per Preferred Security and Common Security
plus  accrued  and unpaid  Distributions  thereon  to the date of payment  (such
amount being the "Liquidation  Distribution"),  unless,  in connection with such
dissolution, winding-up or termination, and after




                                       3



satisfaction of liabilities to creditors,  Debentures in an aggregate  principal
amount  equal to the  aggregate  stated  liquidation  amount  of such  Preferred
Securities  and Common  Securities  bearing  accrued  and unpaid  interest in an
amount  equal  to the  accrued  and  unpaid  Distributions  on,  such  Preferred
Securities and Common  Securities,  shall be distributed Pro Rata to the Holders
of  the  Preferred  Securities  and  Common  Securities  in  exchange  for  such
Securities.

         If, upon any such dissolution, the Liquidation Distribution can be paid
only in part because the Trust has insufficient  assets available to pay in full
the aggregate Liquidation Distribution, then the amounts payable directly by the
Trust on the Preferred  Securities and Common Securities shall be paid,  subject
to the next paragraph, on a Pro Rata basis.

         Holders of Common  Securities  will be entitled to receive  Liquidation
Distributions  upon any such  dissolution  Pro Rata with  Holders  of  Preferred
Securities,  except that if an Event of Default has occurred and is  continuing,
the Preferred  Securities shall have a priority over the Common  Securities with
respect to such Liquidation Distribution.

         4. REDEMPTION AND DISTRIBUTION OF DEBENTURES.  The Preferred Securities
and Common  Securities  may only be redeemed if  Debentures  having an aggregate
principal  amount equal to the  aggregate  liquidation  amount of the  Preferred
Securities  and Common  Securities  are repaid,  redeemed or  distributed as set
forth below:

         (a) Upon the repayment of the Debentures,  in whole or in part, whether
at  maturity,  upon  redemption  at any  time or from  time to time on or  after
September 30, 2000, or at any time in certain  circumstances upon the occurrence
of a Tax Event,  the  proceeds of such  repayment  will be  promptly  applied to
redeem Pro Rata Preferred  Securities and Common  Securities having an aggregate
liquidation amount equal to the aggregate  principal amount of the Debentures so
repaid or redeemed,  upon not less than 30 nor more than 60 days'  notice,  at a
redemption price per Preferred and Common Security equal to the redemption price
of the  Debentures,  together  with  accrued  and unpaid  Distributions  thereon
through the date of redemption,  payable in cash (the "Redemption  Price").  The
date of any such  repayment or  redemption  of Preferred  Securities  and Common
Securities  shall be  established  to coincide  with the repayment or redemption
date of the Debentures.

         (b) If fewer than all the outstanding  Preferred  Securities and Common
Securities  are to be so  redeemed,  the  Preferred  Securities  and the  Common
Securities  will be redeemed Pro Rata and the Common  Securities  to be redeemed
will be  redeemed  as  described  in  paragraph  4(e)(ii)  below.  If a  partial
redemption  would result in the  delisting of the  Preferred  Securities  by any
national  securities  exchange  or other  organization  on which  the  Preferred
Securities are then listed, AES pursuant





                                       4



to the  Indenture  will only redeem  Debentures  in whole and, as a result,  the
Trust may only redeem the Common Securities in whole.

         (c) If, at any time, a Tax Event or an  Investment  Company Event (each
as  hereinafter  defined,  and  each  a  "Special  Event")  shall  occur  and be
continuing,  the Regular  Trustees shall,  unless the Debentures are redeemed in
the  limited  circumstances  described  below,  dissolve  the Trust  and,  after
satisfaction of creditors,  cause Debentures held by the Property Trustee having
an aggregate  principal amount equal to the aggregate stated  liquidation amount
of and accrued and unpaid interest equal to accrued and unpaid Distributions on,
and having the same  record  date for payment as the  Preferred  Securities  and
Common Securities,  to be distributed to the Holders of the Preferred Securities
and  Common  Securities  on a Pro Rata  basis in  liquidation  of such  Holders'
interests in the Trust,  within 90 days following the occurrence of such Special
Event  (the  "90  Day  Period");  provided,  however,  that  in the  case of the
occurrence of a Tax Event, as a condition of such dissolution and  distribution,
the Regular  Trustees shall have received an opinion of a nationally  recognized
independent  tax  counsel   experienced  in  such  matters  (a  "No  Recognition
Opinion"),  which  opinion  may rely on any then  applicable  published  revenue
rulings of the Internal Revenue  Service,  to the effect that the Holders of the
Preferred  Securities  will not  recognize  any gain or loss for  United  States
federal  income tax  purposes  as a result of the  dissolution  of the Trust and
distribution of Debentures;  and provided,  further,  that, if and as long as at
the time there is available to the Trust the  opportunity  to eliminate,  within
such 90 Day Period, the Special Event by taking some ministerial action, such as
filing a form or making an election,  or pursuing some other similar  reasonable
measure  that has no  adverse  effect on the  Trust,  AES or the  Holders of the
Preferred Securities  ("Ministerial  Action") the Trust will pursue such measure
in lieu of dissolution.

         If in the  case of the  occurrence  of a Tax  Event,  (i)  the  Regular
Trustees  have  received an opinion (a  "Redemption  Tax Opinion") of nationally
recognized independent tax counsel experienced in such matters that, as a result
of a Tax  Event,  there is more  than an  insubstantial  risk  that AES would be
precluded  from  deducting  the  interest on the  Debentures  for United  States
federal  income tax purposes  even if the  Debentures  were  distributed  to the
Holders of Preferred  Securities  and Common  Securities in  liquidation of such
Holder's  interest in the Trust as described in this  paragraph 4(c) or (ii) the
Regular  Trustees  shall  have  been  informed  by such  tax  counsel  that a No
Recognition  Opinion cannot be delivered to the Trust,  AES shall have the right
at any time, upon not less than 30 nor more than 60 days' notice,  to redeem the
Debentures in whole or in part for cash at the  Redemption  Price within 90 days
following  the  occurrence  of such  Tax  Event,  and  promptly  following  such
redemption   Preferred  Securities  and  Common  Securities  with  an  aggregate
liquidation amount equal to the aggregate  principal amount of the Debentures so
redeemed  will be  redeemed by the Trust at the  Redemption  Price on a Pro Rata
basis: provided,




                                       5



however,  that, if at the time there is available to AES or the Regular Trustees
on behalf of the Trust the opportunity to eliminate,  within such 90 day period,
the Tax Event by taking  some  Ministerial  Action,  AES or the  Holders  of the
Preferred  Securities,  AES or the Regular  Trustees on behalf of the Trust will
pursue such measure in lieu of redemption; and provided, further, that AES shall
have no right to redeem the Debentures  while the Regular  Trustees on behalf of
the Trust are pursuing such Ministerial  Action.  The Common  Securities will be
redeemed  Pro Rata with the  Preferred  Securities,  except  that if an Event of
Default  under the  Indenture  has occurred  and is  continuing,  the  Preferred
Securities  will have a priority  over the  Common  Securities  with  respect to
payment of the Redemption Price.

         "Tax Event"  means that the  Regular  Trustees  shall have  obtained an
opinion of nationally  recognized  independent  tax counsel  experienced in such
matters (a "Dissolution Tax Opinion") to the effect that on or after October 23,
1997 as a result of (a) any  amendment  to, or change  (including  any announced
prospective  change) in, the laws (or any regulations  thereunder) of the United
States or any political  subdivision or taxing authority thereof or therein, (b)
any amendment to, or change in, an  interpretation  or  application  of any such
laws or regulations  by any  legislative  body,  court,  governmental  agency or
regulatory  authority  (including  the  enactment  of any  legislation  and  the
publication  of any  judicial  decision or  regulatory  determination),  (c) any
interpretation  or  pronouncement  that  provides for a position with respect to
such laws or regulations  that differs from the theretofore  generally  accepted
position  or (d) any  action  taken by any  governmental  agency  or  regulatory
authority,  which  amendment  or  change  is  enacted,  promulgated,  issued  or
announced or which  interpretation  or  pronouncement  is issued or announced or
which action is taken, in each case on or after October 23, 1997,  there is more
than an  insubstantial  risk that (i) the Trust is, or will be within 90 days of
the date thereof,  subject to United States  federal  income tax with respect to
income  accrued or  received  on the  Debentures,  (ii) the Trust is, or will be
within 90 days of the date thereof,  subject to more than a de minimis amount of
taxes, duties or other governmental  charges or (iii) interest payable by AES to
the Trust on the  Debentures  is not, or within 90 days of the date thereof will
not be, deductible by AES for United States federal income tax purposes.

         "Investment  Company Event" means that the Regular  Trustees shall have
received an opinion of nationally recognized  independent counsel experienced in
practice under the Investment Company Act that, as a result of the occurrence of
a change in law or regulation or a change in  interpretation  or  application of
law or  regulation  by any  legislative  body,  court,  governmental  agency  or
regulatory  authority  (a  "Change  in 1940 Act  Law"),  there  is more  than an
insubstantial risk that the Trust is or will be considered an Investment Company
which is required to be  registered  under the  Investment  Company  Act,  which
Change in 1940 Act Law becomes effective on or after October 23, 1997.





                                       6



         On the date fixed for any distribution of Debentures,  upon dissolution
of the  Trust,  (i)  the  Common  Securities  will no  longer  be  deemed  to be
outstanding and (ii) any  certificates  representing  Common  Securities will be
deemed to represent  beneficial  interests in the Debentures having an aggregate
principal amount equal to the stated  liquidation amount of, and bearing accrued
and unpaid  interest equal to accrued and unpaid  Distributions  on, such Common
Securities  until  such  certificates  are  presented  to AES or its  agent  for
transfer or reissuance.

         (d) The Trust may not redeem any outstanding  Common  Securities unless
all accrued and unpaid Distributions have been paid on all Common Securities for
all  quarterly  Distribution  periods  terminating  on or  prior  to the date of
redemption.

         (e)(i)  Notice of any  redemption  of, or  notice  of  distribution  of
Debentures in exchange for, the Preferred  Securities  and Common  Securities (a
"Redemption/  Distribution  Notice")  will be given by the  Regular  Trustees on
behalf of the Trust by mail to each Holder of  Preferred  Securities  and Common
Securities  to be redeemed or  exchanged  not less than 30 nor more than 60 days
prior to the date fixed for redemption or exchange thereof.  For purposes of the
calculation of the date of redemption or exchange and the dates on which notices
are given pursuant to this paragraph  (e)(i), a  Redemption/Distribution  Notice
shall  be  deemed  to be  given  on the day  such  notice  is  first  mailed  by
first-class mail, postage prepaid, to Holders of Preferred Securities and Common
Securities.  Each  Redemption/Distribution  Notice  shall  be  addressed  to the
Holders of Preferred  Securities  and Common  Securities  at the address of each
such Holder  appearing  in the books and records of the Trust.  No defect in the
Redemption/Distribution  Notice or in the mailing of either thereof with respect
to  any  Holder  shall  affect  the  validity  of  the  redemption  or  exchange
proceedings with respect to any other Holder.

         (ii) In the event that fewer than all the outstanding Common Securities
are to be redeemed,  the Common  Securities  to be redeemed will be redeemed Pro
Rata from each Holder of Common  Securities  (subject to adjustment to eliminate
fractional Common Securities).

         (iii) If the Trust gives a Redemption/Distribution Notice in respect of
a redemption of Common  Securities as provided in this paragraph 4 (which notice
will be  irrevocable)  then  immediately  prior to the close of  business on the
redemption  date,  provided  that  AES  has  paid  to the  Property  Trustee  in
immediately  available funds a sufficient  amount of cash in connection with the
related  redemption or maturity of the Debentures,  Distributions  will cease to
accrue on the Common  Securities  called for redemption,  such Common Securities
will no longer be deemed to be  outstanding  and all  rights of  Holders of such
Common  Securities so called for redemption will cease,  except the right of the
Holders of such Common  Securities to receive the Redemption  Price, but without
interest on such Redemption Price.

Neither the  Trustees nor the Trust shall be required to register or cause to be
registered the transfer of any Common  Securities  which have been so called for
redemption.  If any date  fixed for  redemption  of Common  Securities  is not a
Business Day, then payment of the Redemption  Price payable on such date will be
made on the next succeeding day that is a Business Day (and without any interest
or other payment in respect of any such delay) except that, if such Business Day
falls in the next calendar  year,  such payment will be made on the  immediately
preceding  Business  Day, in each case with the same force and effect as if made
on such date fixed for redemption. If payment of the Redemption Price in respect
of Common  Securities  is  improperly  withheld  or refused  and not paid by the
Property  Trustee,  Distributions  on such Common  Securities  will  continue to
accrue,  from the original redemption date to the date of payment, in which case
the actual  payment date will be considered  the date fixed for  redemption  for
purposes of calculating the Redemption Price.

         (iv)  Redemption/Distribution  Notices  shall  be sent  by the  Regular
Trustees on behalf of the Trust to the Holders of the Common Securities.

         (v) Upon the date of  dissolution  of the  Trust  and  distribution  of
Debentures as a result of the  occurrence of a Special  Event,  Common  Security
Certificates shall be deemed to represent beneficial interests in the Debentures
so distributed,  and the Common Securities will no longer be deemed  outstanding
and may be canceled by the Regular Trustees. The Debentures so distributed shall
have an aggregate principal amount equal to the aggregate  liquidation amount of
the Common Securities so distributed.

         5. CONVERSION RIGHTS. The Holders of Securities shall have the right at
any time prior to the close of business on  September  30, 2012 (or, in the case
of  Securities  called for  redemption,  prior to the close of  business  on the
Business  Day  prior to the  redemption  date),  at their  option,  to cause the
Conversion  Agent to convert  Securities,  on behalf of the converting  Holders,
into shares of Common Stock in the manner described herein on and subject to the
following terms and conditions:

         The  Securities  will be  convertible  at the office of the  Conversion
Agent into fully paid and  nonassessable  shares of Common Stock pursuant to the
Holder's  direction to the  Conversion  Agent to exchange such  Securities for a
portion  of the  Debentures  theretofore  held by the  Trust on the basis of one
Security per $50 principal  amount of Debentures,  and immediately  convert such
amount of Debentures into fully paid and nonassessable shares of Common Stock at
an initial  rate of 0.8914  shares of Common Stock per $50  principal  amount of
Debentures  (which is  equivalent  to a conversion  price of $56.09 per share of
Common Stock, subject to certain adjustments set forth in Sections 5.03 and 5.04
of the Supplemental Indenture (as so adjusted, "Conversion Price")).



                                       8



         (a) In order to convert  Securities  into Common Stock the Holder shall
submit to the  Conversion  Agent at the office  referred to above an irrevocable
request  to  convert  Securities  on  behalf  of such  Holder  (the  "Conversion
Request"),  together,  if the Securities  are in  certificated  form,  with such
certificates.  The  Conversion  Request  shall  (i)  set  forth  the  number  of
Securities to be converted and the name or names,  if other than the Holder,  in
which the shares of Common Stock should be issued and (ii) direct the Conversion
Agent (a) to exchange such  Securities for a portion of the  Debentures  held by
the Trust (at the rate of exchange specified in the preceding paragraph) and (b)
to  immediately  convert such  Debentures on behalf of such Holder,  into Common
Stock  (at the  conversion  rate  specified  in the  preceding  paragraph).  The
Conversion Agent shall notify the Property  Trustee of the Holder's  election to
exchange  Securities for a portion of the  Debentures  held by the Trust and the
Property Trustee shall,  upon receipt of such notice,  deliver to the Conversion
Agent the appropriate  principal amount of Debentures for exchange in accordance
with this Section.  The  Conversion  Agent shall  thereupon  notify the Property
Trustee of the  Holder's  election  to convert  such  Debentures  into shares of
Common Stock.  If a Security is surrendered  for  conversion  after the close of
business on any regular record date for payment of a Distribution and before the
opening of  business  on the  corresponding  Distribution  payment  date,  then,
notwithstanding  such conversion,  the Distribution payable on such Distribution
payment  date will be paid in cash to the person in whose name the  Security  is
registered  at the close of  business  on such  record  date,  and (other than a
Security or a portion of a Security  called for redemption on a redemption  date
occurring  after such record date and on or prior to such  Distribution  payment
date) when so surrendered  for  conversion,  the Security must be accompanied by
payment of an amount  equal to the  Distribution  payable  on such  Distribution
payment date.  Except as provided above,  neither the Trust nor the Sponsor will
make,  or be required to make,  any payment,  allowance or  adjustment  upon any
conversion on account of any accumulated and unpaid Distributions accumulated on
the Securities surrendered for conversion,  or on account of any accumulated and
unpaid  dividends  on the shares of Common  Stock  issued upon such  conversion.
Securities shall be deemed to have been converted immediately prior to the close
of business on the day on which a Conversion Request relating to such Securities
is  received  by the  Trust in  accordance  with the  foregoing  provision  (the
"Conversion  Date").  The Person or Persons  entitled  to receive  Common  Stock
issuable upon conversion of the Debentures  shall be treated for all purposes as
the record  holder or holders of such Common Stock at such time.  As promptly as
practicable on or after the Conversion Date, the Sponsor shall issue and deliver
at the office of the  Conversion  Agent a certificate  or  certificates  for the
number of full shares of Common Stock  issuable upon such  conversion,  together
with the cash  payment,  if any,  in lieu of any  fraction  of any  share to the
Person or Persons entitled to receive the same, unless otherwise directed by the
Holder in the Conversion  Request and the Conversion Agent shall distribute such
certificate or certificates,  together with the applicable cash payment, if any,
to such Person or Persons.




                                       9



         (b) Each Holder of a Security by his  acceptance  thereof  appoints The
First National Bank of Chicago  "Conversion  Agent" for the purpose of effecting
the conversion of Securities in accordance  with this Section.  In effecting the
conversion and  transactions  described in this Section,  the  Conversion  Agent
shall be acting as agent of the  Holders of  Securities  directing  it to effect
such conversion  transactions.  The Conversion Agent is hereby authorized (i) to
exchange  Securities  from  time to time  for  Debentures  held by the  Trust in
connection  with the  conversion  of such  Securities  in  accordance  with this
section and (ii) to convert all or a portion of the Debentures into Common Stock
and  thereupon  to deliver such shares of Common  Stock in  accordance  with the
provisions  of this  section  and to  deliver  to the Trust a new  Debenture  or
Debentures for any resulting unconverted principal amount.

         (c) No fractional  shares of Common Stock will be issued as a result of
conversion,  but in lieu thereof,  such fractional interest will be paid in cash
by the Company to the Conversion Agent,  which in turn will make such payment to
the Holder or Holders of Securities so converted.

         (d) The Sponsor  shall at all times  reserve and keep  available out of
its  authorized  and  unissued  Common  Stock,  solely  for  issuance  upon  the
conversion of the Debentures,  free from any preemptive or other similar rights,
such  number of shares of Common  Stock as shall  from time to time be  issuable
upon the conversion of all the Debentures then outstanding.  Notwithstanding the
foregoing, shall be entitled to deliver upon conversion of Debentures, shares of
Common Stock  reacquired and held in the treasury of the Sponsor (in lieu of the
issuance of authorized and unissued shares of Common Stock), so long as any such
treasury shares are free and clear of all liens, charges,  security interests or
encumbrances.  Any  shares  of  Common  Stock  issued  upon  conversion  of  the
Debentures  shall  be  duly  authorized,  validly  issued  and  fully  paid  and
nonassessable.  The Trust shall deliver the shares of Common Stock received upon
conversion  of the  Debentures  to the  converting  Holder free and clear of all
liens,  charges,  security interests and encumbrances,  except for United States
withholding taxes. Each of the Sponsor and the Trust shall prepare and shall use
its best  efforts to obtain and keep in force such  governmental  or  regulatory
permits or other authorizations as may be required by law, and shall comply with
all applicable  requirements as to registration or qualification of Common Stock
(and  all  requirements  to  list  Common  Stock  issuable  upon  conversion  of
Debentures that are at the time  applicable),  in order to enable the company to
lawfully  issue Common Stock to the Trust upon  conversion of the Debentures and
the Trust to lawfully deliver Common Stock to each Holder upon conversion of the
Securities.

         (e) The  Sponsor  will pay any and all  taxes  that may be  payable  in
respect of the issue or  delivery  of shares of Common  Stock on  conversion  of
Debentures  and the  delivery  of the  shares of Common  Stock by the Trust upon
conversion of the Securities. The Sponsor shall not, however, be required to pay
any tax which may be



                                       10



payable in respect of any transfer  involved in the issue and delivery of shares
of Common Stock in a name other than that in which the  Securities  so converted
were  registered,  and no such issue or delivery  shall be made unless and until
the  person  requesting  such issue has paid to the Trust the amount of any such
tax, or has established to the  satisfaction of the Trust that such tax has been
paid.

         (f) Nothing in the preceding  Paragraph (e) shall limit the requirement
of the Trust to withhold  taxes  pursuant to the terms of the  Securities or set
forth in this  Exhibit  C to the  Declaration  or to the  Declaration  itself or
otherwise  require  the  Property  Trustee  or the Trust to pay any  amounts  on
account of such withholdings.

         6. VOTING RIGHTS. (a) Except as provided under paragraph 5(b) below and
as  otherwise  required  by law and the  Declaration,  the Holders of the Common
Securities will have no voting rights.

         (b)  Holders  of  Common  Securities  have the  sole  right  under  the
Declaration  to  increase or decrease  the number of  Trustees,  and to appoint,
remove or replace a Trustee, any such increase, decrease,  appointment,  removal
or  replacement  to be approved by Holders of Common  Securities  representing a
Majority in liquidation amount of the Common Securities.

         If any  proposed  amendment  to the  Declaration  provides  for, or the
Regular  Trustees  otherwise  propose  to  effect,  (i) any  action  that  would
adversely  affect the powers,  preferences or special rights of the  Securities,
whether  by way of  amendment  to the  Declaration  or  otherwise,  or (ii)  the
dissolution,  winding-up or termination  of the Trust,  other than in connection
with the  distribution  of  Debentures  held by the Property  Trustee,  upon the
occurrence  of a Special Event or in  connection  with the  redemption of Common
Securities as a consequence of a redemption of  Debentures,  then the Holders of
outstanding Securities will be entitled to vote on such amendment or proposal as
a class and such  amendment or proposal  shall not be effective  except with the
approval of the Holders of  Securities  representing  a Majority in  liquidation
amount of such  Securities;  provided,  however,  that (A) if any  amendment  or
proposal  referred  to in  clause  (i) above  would  adversely  affect  only the
Preferred Securities or the Common Securities, then only the affected class will
be entitled to vote on such amendment or proposal and such amendment or proposal
shall not be  effective  except with the  approval of a Majority in  liquidation
amount  of such  class of  Securities,  (B) the  rights  of  Holders  of  Common
Securities  under  Article 4.02 of the  Declaration  to increase or decrease the
number of, and to  appoint,  replace  or remove,  Trustees  shall not be amended
without the consent of each Holder of Common  Securities,  and (C) amendments to
the Declaration  shall be subject to such further  requirements as are set forth
in Sections 12.01 and 12.02 of the Declaration.






                                       11



         In the event the consent of the  Property  Trustee as the holder of the
Debentures,  is required  under the  Indenture  with  respect to any  amendment,
modification  or  termination of the Indenture or the  Debentures,  the Property
Trustee  shall  request the written  direction of the Holders of the  Securities
with  respect to such  amendment,  modification  or  termination.  The  Property
Trustee shall vote with respect to such  amendment,  modification or termination
as  directed  by a  Majority  in  liquidation  amount of the  Securities  voting
together as a single class; provided that where such amendment,  modification or
termination  of the  Indenture  requires  the  consent or vote of (1) holders of
Debentures  representing  a  specified  percentage  greater  than a majority  in
principal  amount  of the  Debentures  or (2) each  holder  of  Debentures,  the
Property  Trustee may only vote with respect to that amendment,  modification or
termination as directed by, in the case of clause (1) above, the vote of Holders
of  Securities   representing   such  specified   percentage  of  the  aggregate
liquidation amount of the Securities,  or, in the case of clause (2) above, each
Holder of Securities; and provided,  further, that the Property Trustee shall be
under no obligation to take any action in accordance  with the directions of the
Holders of the Securities  unless the Property  Trustee shall have received,  at
the expense of the Sponsor, an opinion of nationally recognized  independent tax
counsel  recognized  as an expert in such  matters to the effect  that the Trust
will not be  classified  for United  States  federal  income tax  purposes as an
association  taxable as a corporation or a partnership on account of such action
and will be treated  as a grantor  trust for United  States  federal  income tax
purposes following such action.

         Subject to Section 2.06 of the Declaration,  and the provisions of this
and the next  succeeding  paragraph,  the Holders of a Majority  in  liquidation
amount of the Common  Securities,  voting  separately  as a class shall have the
right to (A) on  behalf of all  Holders  of  Common  Securities,  waive any past
default that is waivable  under the  Declaration  (subject to, and in accordance
with the Declaration) and (B) direct the time,  method,  and place of conducting
any proceeding for any remedy available to the Property  Trustee,  or exercising
any trust or power  conferred upon the Property  Trustee under the  Declaration,
including the right to direct the Property Trustee, as holder of the Debentures,
to (i) direct the time,  method and place of conducting  any  proceeding for any
remedy  available to the Debenture  Trustee,  or  exercising  any trust or power
conferred on the Debenture  Trustee with respect to the  Debentures,  (ii) waive
any past default and its consequences that is waivable under Section 6.06 of the
Indenture,  or (iii)  exercise any right to rescind or annul a declaration  that
the  principal of all the  Debentures  shall be due and payable;  provided  that
where the taking of any action under the Indenture  requires the consent or vote
of (1) holders of Debentures  representing a specified percentage greater than a
majority in principal amount of the Debentures or (e) each holder of Debentures,
the  Property  Trustee may only take such action if directed  by, in the case of
clause (1) above,  the vote of Holders of Common  Securities  representing  such
specified  percentage  of  the  aggregate   liquidation  amount  of  the  Common
Securities, or, in the case of clause (2) above, each Holder of Common





                                       12



Securities.  Pursuant to this paragraph,  the Property Trustee shall not revoke,
or take any action  inconsistent  with,  any  action  previously  authorized  or
approved by a vote of the  Holders of the  Preferred  Securities,  and shall not
take any action in  accordance  with the  direction of the Holders of the Common
Securities  under this  paragraph if the action is prejudicial to the Holders of
Preferred Securities.  Other than with respect to directing the time, method and
place of  conducting  any  proceeding  for any remedy  available to the Property
Trustee or the Debenture  Trustee as set forth above, the Property Trustee shall
be under no obligation to take any of the foregoing  actions at the direction of
the  Holders of Common  Securities  unless  the  Properties  Trustee  shall have
received,  at the expense of the Sponsor,  an opinion of  nationally  recognized
independent tax counsel  recognized as expert in such matters to the effect that
the Trust will not be classified  for United States  federal income tax purposes
as an  association  taxable as a corporation or a partnership on account of such
action  and will be  treated as a grantor  trust for  United  States  income tax
purposes following such action.

         Notwithstanding  any other  provision  of these  terms,  each Holder of
Common  Securities  will be deemed to have  waived  any  Event of  Default  with
respect  to the  Common  Securities  and its  consequences  until all  Events of
Default with respect to the Preferred  Securities have been cured, waived by the
Holders of  Preferred  Securities  as provided in the  Declaration  or otherwise
eliminated,  and until all  Events of  Default  with  respect  to the  Preferred
Securities have been so cured, waived by the Holders of Preferred  Securities or
otherwise eliminated, the Property Trustee will be deemed to be acting solely on
behalf of the  Holders  of  Preferred  Securities  and only the  Holders  of the
Preferred  Securities  will have the right to direct  the  Property  Trustee  in
accordance with the terms of the Declaration or of the Securities.  In the event
that any Event of Default with respect to the Preferred  Securities is waived by
the Holders of Preferred Securities as provided in the Declaration,  the Holders
of Common  Securities agree that such waiver shall also constitute the waiver of
such Event of Default  with  respect to the Common  Securities  for all purposes
under the Declaration without any further act, vote or consent of the Holders of
the Common Securities.

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

         Any required approval of Holders of Common Securities may be given at a
separate meeting of Holders of Common Securities convened for such purpose, at a
meeting of all of the Holders of  Securities of the Trust or pursuant to written
consent.  The  Regular  Trustees  will  cause a notice of any  meeting  at which
Holders of Common  Securities  are entitled to vote, or of any matter upon which
action by written  consent of such Holders is to be taken,  to be mailed to each
Holder of record of Common Securities. Each such notice will include a statement
setting forth (i) the date of such





                                       13



meeting or the date by which such action is to be taken,  (ii) a description  of
any  resolution  proposed for adoption at such meeting on which such Holders are
entitled  to vote or of such  matter  upon which  written  consent is sought and
(iii) instructions for the delivery of proxies or consents.

         No vote or consent of the Holders of Common Securities will be required
for the Trust to redeem and cancel  Common  Securities  in  accordance  with the
Declaration.

         7.  PRO RATA  TREATMENT.  A  reference  in  these  terms of the  Common
Securities to any payment,  distribution  or treatment as being "Pro Rata" shall
mean  pro  rata  to  each  Holder  of  Securities  according  to  the  aggregate
liquidation  amount of the Securities held by the relevant Holder in relation to
the  aggregate  liquidation  amount of all  Securities  outstanding  unless,  in
relation to a payment,  an Event of Default has occurred and is  continuing,  in
which case any funds  available to make such payment shall be paid first to each
Holder  of  the  Preferred  Securities  pro  rata  according  to  the  aggregate
liquidation amount of Preferred  Securities held by the relevant Holder relative
to the aggregate liquidation amount of all Preferred Securities outstanding, and
only after  satisfaction  of all amounts  owed to the  Holders of the  Preferred
Securities,  to each  Holder  of Common  Securities  pro rata  according  to the
aggregate  liquidation  amount of Common  Securities held by the relevant Holder
relative  to  the  aggregate   liquidation   amount  of  all  Common  Securities
outstanding.

         8. RANKING.  The Common  Securities rank pari passu and payment thereon
will be made Pro Rata with the Preferred  Securities  except that where an Event
of Default occurs and is continuing,  the rights of Holders of Common Securities
to payment in respect of Distributions and payments upon liquidation, redemption
or  otherwise  are  subordinate  to the  rights  of  Holders  of  the  Preferred
Securities.

         9.  MERGERS,  CONSOLIDATIONS  OR  AMALGAMATIONS.   The  Trust  may  not
consolidate,  amalgamate,  merge  with or into,  or be  replaced  by, or convey,
transfer or lease its properties and assets to, any corporation or other body.

         10. TRANSFERS,  EXCHANGES, METHOD OF PAYMENTS. Payment of Distributions
and  payments  on  redemption  of the Common  Securities  will be  payable,  the
transfer of the Common  Securities  will be registrable,  and Common  Securities
will be  exchangeable  for Common  Securities of other  denominations  of a like
aggregate  liquidation  amount,  at the principal  corporate trust office of the
Property Trustee in The City of New York; provided that payment of Distributions
may be made at the  option  of the  Regular  Trustees  on behalf of the Trust by
check mailed to the address of the persons entitled thereto and that the payment
on  redemption of any Common  Security will be made only upon  surrender of such
Common  Security  to  the  Property  Trustee.   Notwithstanding  the  foregoing,
transfers of Common  Securities  are subject to conditions  set forth in Section
9.01(c) of the Declaration.





                                       14



         11. ACCEPTANCE OF INDENTURE.  Each Holder of Common Securities,  by the
acceptance  thereof,   agrees  to  the  provisions  of  the  Indenture  and  the
Debentures, including the subordination provisions thereof.

         12. NO PREEMPTIVE  RIGHTS.  The Holders of Common Securities shall have
no  preemptive  rights to  subscribe  to any  additional  Common  Securities  or
Preferred Securities.

         13.  MISCELLANEOUS.   These  terms  shall  constitute  a  part  of  the
Declaration.  The Trust will provide a copy of the Declaration and the Indenture
to a Holder  without  charge on written  request  to the Trust at its  principal
place of business.

         AES Trust II, a statutory  business  trust formed under the laws of the

the Trust dated as of October 29, 1997,  as the same may be amended from time to

         The Holder of this  Certificate,  by  accepting  this  Certificate,  is

                          [FORM OF REVERSE OF SECURITY]

         Distributions  payable on each Common  Security will be fixed at a rate
per annum of $2.75 per Common  Security,  such rate  being the rate of  interest
payable on the Debentures to be held by the Property  Trustee.  Distributions in
arrears for more than one  quarter  will bear  interest  thereon at the rate per
annum of 5.50% thereof (to the extent permitted by law) compounded monthly.  The
term  "Distributions"  as used herein means such cash distributions and any such
interest payable unless otherwise  stated. A Distribution is payable only to the
extent that payments are made in respect of the Debentures  held by the Property
Trustee. The amount of Distributions  payable for any period will be computed on
the basis of a 360-day year of twelve 30-day months.

         Except  as  otherwise  described  below,  distributions  on the  Common
Securities  will be  cumulative,  will accrue from  October 29, 1997 and will be
payable  quarterly in arrears,  on the last day of each  quarter,  commencing on
December 31, 1997, but only if and to the extent that interest payments are made
in respect of the Debentures held by the Property Trustee.  So long as AES shall
not be in default in the  payment of  interest  on the  Debentures,  AES has the
right under the  Indenture for the  Debentures to defer  payments of interest by
extending the interest  payment period from time to time on the Debentures for a
period not exceeding 20 consecutive  quarters (each an "Extension  Period") and,
as a consequence,  quarterly Distributions will continue to accrue with interest
thereon (to the extent  permitted  by  applicable  law) at the rate of 5.50% per
annum,  compounded  quarterly  during such  Extension  period;  provided that no
Extension  Period shall last beyond the date of maturity or any redemption  date
of the Debentures.  Prior to the termination of any such Extension  Period,  AES
may  commence  a new  Extension  Period;  provided  that such  Extension  Period
together with all such previous and further extensions thereof may not exceed 20
consecutive  quarterly interest periods.  Payments of accrued Distributions will
be payable to  Holders as they  appear on the books and  records of the Trust on
the  first  record  date  after  the  end  of the  Extension  Period.  Upon  the
termination of any Extension Period and the payment of all amounts then due, AES
may commence a new Extension Period, subject to the above requirements.

         The  Common   Securities   shall  be  redeemable  as  provided  in  the
Declaration.

         The Common Securities shall be convertible into shares of Common Stock,
through (i) the exchange of Common  Securities  for a portion of the  Debentures
and (ii) the immediate  conversion of such  Debentures into Common Stock, in the
manner and according to the terms set forth in the Declaration.
