          (i) which is not waivable  under the  Indenture,  the Event of Default
     under this Declaration shall also be not waivable; or

          (ii) which  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 Event of
     Default under this Declaration may only be waived 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.

     Upon such waiver,  any such default shall cease to exist,  and any Event of
Default with respect to the  Preferred  Securities  arising  therefrom  shall be
deemed to have been  cured for every  purpose of this  Declaration,  but no such
waiver shall extend to any  subsequent or other default or Event of Default with
respect to the Preferred Securities or impair any right consequent thereon.

     (b) Subject to Section 2.06(c), Holders of Common Securities may by vote of

Event of Default with  respect to the Common  Securities  and its  consequences,
provided  that,  if the Event of  Default  arises out of an  Indenture  Event of
Default:

          (i)  which is not  waivable  under  the  Indenture,  except  where the
     Holders of the Common  Securities  are deemed to have  waived such Event of
     Default under the Declaration as provided below, the Event of Default under
     this Declaration shall also not be waivable; or

                                       10





          (ii) which  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, except where the
     holders of the Common  Securities  are deemed to have  waived such Event of
     Default  under this  Declaration  as provided  below,  the Event of Default
     under  this  Declaration  may only be waived  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 Securities; and

provided,  further, that 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 this  Declaration  or otherwise  eliminated  and until all Events of
Default with respect to the Preferred  Securities have been so cured,  waived or
otherwise eliminated, the Property Trustee will be deemed to be acting solely on
behalf of the Holders of the  Preferred  Securities  and only the Holders of the
Preferred  Securities  will have the right to direct  the  Property  Trustee  in
accordance with the terms of this  Declaration or 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 this 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 this  Declaration  without any further act, vote or consent of the Holders
of the Common  Securities.  Subject to the foregoing  provisions of this Section
2.06(b),  upon such waiver,  any such default shall cease to exist and any Event
of Default  with respect to the Common  Securities  arising  therefrom  shall be
deemed to have been  cured for every  purpose of this  Declaration,  but no such
waiver shall extend to any  subsequent or other default or Event of Default with
respect to the Common Securities or impair any right consequent thereon.

terms of the Securities set forth in Exhibits B and C on or after the respective
payment dates  therefor,  or to institute  suit for the  enforcement of any such
payment  on or after such  payment  dates,  shall not be  impaired  without  the
consent of such Holder.

     (d) As provided in the terms of the  Securities set forth in Exhibits B 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

                                       11





the  corresponding  Event of Default  under this  Declaration  in respect of the
Securities.

to the names and addresses of the Holders of the  Securities in accordance  with
ss. 312 of the Trust  Indenture  Act,  regardless  of the source from which such
information  was derived,  shall not be deemed to be a violation of any existing
law, or any law hereafter  enacted which does not specifically  refer to ss. 312
of the Trust Indenture Act, nor shall the Property  Trustee be held  accountable
by reason of mailing any material pursuant to a request made under ss. 312(b) of
the Trust Indenture Act.

          (iii) the Trust  will  comply  with any  requirements  imposed  by any

          (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

                                       19





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 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:


                                       20





          (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  of the Regular  Trustees and the Property  Trustee
(except as required under the Business Trust Act) described in this Declaration.
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

                                       21





of all Events of Default that may have occurred, shall undertake to perform only
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


                                       22





     and place of  conducting  any  proceeding  for any remedy  available to the
     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;


                                       23




          (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
     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.  Registration  Statement and Related  Matters.  In accordance
with  the  Original  Declaration,  AES  and the  Trustees  have  authorized  and

     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 

                                       28





     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 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


                                       29





          (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  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


                                       30





          (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.

     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

                                       31





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 (including,  without
limitation to filings referred to in Section 3.13).

     (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.


                                       32





                                    ARTICLE 7
                             ISSUANCE OF SECURITIES

     SECTION 7.01.  General  Provisions  Regarding  Securities.  (a) The Regular
Trustees shall issue on behalf of the Trust  securities in fully registered form
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.  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

                                       33





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.


                                       34




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

                              TERMINATION OF TRUST

     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

     (c) upon the  expiration  of the term of the Trust as set forth in  Section
3.17; 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.


                                       35





     (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.

     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.

                                       36





     SECTION 9.04. Book Entry Interests. 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
Underwriting  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.  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:

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

     (b) (i) 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;

     (c) 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

     (d) 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

                                       37





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  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.  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 in delivery of such instructions and each of them may conclusively rely on
and shall be protected in relying on, such instructions.

     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

                                       38






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.

Declaration or by law, except that an Indemnified Person shall be liable for any
such loss, damage or claim incurred by reason of such Indemnified Person's gross
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 or
statements  presented  to the Trust by any Person as to matters the  Indemnified
Person reasonably believes are within such other Person's professional or expert

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

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

Trust,  and the Trust and the  Holders  of  Securities  shall  have no rights 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
(individually  or as a partner or  fiduciary) or to recommend to others any such
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
appropriate taxing authority, an annual United States federal income tax return,
on such form as is required by the Code, and any other annual income tax returns

     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 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

                                       42





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.

                                       43





     (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

                                       44





     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.

                                    TERMS OF
                              PREFERRED SECURITIES

     Pursuant to Section 7.01 of the Amended and Restated  Declaration  of Trust
of AES Trust I dated as of March 31,  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 Two Hundred and Fifty
Million  Dollars  ($250,000,000)  (plus up to an additional  Twenty Five Million
Dollars  ($25,000,000)  issuable upon exercise of the  overallotment  option set
forth in the Underwriting  Agreement) and a liquidation  amount in the assets of
the Trust of $50 per Preferred Security,  are hereby designated as "$2.6875 Term
Convertible   Securities,   Series  A".  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  5.375%  (the  "Coupon  Rate")  of the  stated
liquidation amount of $50 per Preferred  Security.  Distributions in arrears for
more  than one  calendar  quarter  will bear  interest  at the rate per annum of
5.375% 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 March 31, 1997 and will be payable quarterly in arrears, on the last
day of each quarter  commencing on June 30, 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
5.375% 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

                                       2





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  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

                                       3





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 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 March 31,
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 

                                       4





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 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

                                       5





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,  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 March 24, 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  March 24,  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

                                       6





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 March 24, 1997.

     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

                                       7





Agency   Participant  (or  person  on  whose  behalf  such  nominee  holds  such
securities) in accordance with the procedures applied by such agency or nominee.

     (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.


                                       8





     (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 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 March 31,  2027  (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 0.6906  shares of Common Stock per $50  principal  amount of
Debentures  (which is  equivalent  to a conversion  price of $72.40 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

                                       9





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 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

                                       10





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 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
Company ("DTC") or a nominee of DTC. This Preferred Security is exchangeable for
Preferred  Securities  registered  in the name of a person other than DTC or its

transfer of this  Preferred  Security  (other than a transfer of this  Preferred
Security  as a whole by DTC to a nominee of DTC or by a nominee of DTC to DTC or
another nominee of DTC) may be registered except in limited circumstances.

     Unless this Preferred Security is presented by an authorized representative
of The Depository Trust Company (55 Water Street,  New York) to the Trust or its

representing   undivided  beneficial  interests  in  the  assets  of  the  Trust

authorized  attorney,  upon surrender of this  certificate  duly endorsed and in
proper form for transfer. The designations,  rights,  privileges,  restrictions,

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

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

                          [FORM OF REVERSE OF SECURITY]

     Distributions  payable on each  Preferred  Security will be fixed at a rate
per  annum of 5.375 % of the  stated  liquidation  amount  of $50 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  5.375%  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 March 31,  1997 and will be
payable  quarterly in arrears,  on the last day of each  quarter,  commencing on
June 30, 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 5.375% 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.

Debentures on behalf of the  undersigned,  into Common Stock (at the  conversion
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

                                    TERMS OF
                                COMMON SECURITIES

     Pursuant to Section 7.01 of the Amended and Restated  Declaration  of Trust
of AES Capital Trust I dated as of March 31, 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 Seven  Million,  Seven Hundred
and Thirty Two Thousand  Dollars  ($7,732,000)  and a liquidation  amount in the
assets of the Trust of $50 per Common Security, are hereby designated as "5.375%
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 $7,732,000 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  5.375%  (the  "Coupon  Rate")  of  the  stated
liquidation amount of $50 per Common Security. Distributions in arrears for more
than one  calendar  quarter  will bear  interest at the rate per annum of 5.375%
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 March 31, 1997 and will be payable quarterly in arrears, on the last day of
each month commencing on June 30, 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
5.375%  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 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 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

                                       3





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 March 31,
2000, or at any time in certain circustances 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 to the  Indenture  will only redeem
Debentures  in whole  and,  as a result,  the Trust may only  redeem  the Common
Securities in whole.

                                       4





     (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,  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

                                       5





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 March 31, 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  March 31,  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 March 31, 1997.

     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)

                                       6





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

                                       7





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 March 31,  2027  (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 0.6906  shares of Common Stock per $50  principal  amount of
Debentures  (which is  equivalent  to a conversion  price of $72.40 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")).

     (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

                                       8





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.

                          [FORM OF REVERSE OF SECURITY]

     Distributions  payable on each Common  Security will be fixed at a rate per
annum of 5.375% (the "Coupon Rate") of the stated  liquidation amount of $50 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 5.375%  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  March  31,  1997 and  will be  payable
quarterly in arrears,  on the last day of each  quarter,  commencing on June 30,
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 5.375% 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.
