                                    ARTICLE 2

                                 THE SECURITIES

     SECTION  2.1.  Form and Dating.  The  Securities  of each  series  shall be
substantially  in such form or forms (not  inconsistent  with this Indenture) as
shall be established  by or pursuant to one or more Board  Resolutions or in one
or more  indentures  supplemental  hereto,  in each case  with such  appropriate
insertions,  omissions,  substitutions  and other  variations as are required or
permitted by this  Indenture  and may have  imprinted  or  otherwise  reproduced
thereon  such  legend or  legends or  endorsements,  not  inconsistent  with the
provisions of this Indenture, as may be required to comply with any law, or with
any rules of any securities  exchange or usage,  all as may be determined by the
officers  executing  such  Securities  as  evidenced  by their  execution of the
Securities. Unless otherwise so established,  Unregistered Securities shall have
coupons attached.

     SECTION 2.2. Execution and  Authentication.  Two Officers shall execute the
Securities (other than coupons) for the Company by facsimile or manual signature
in the name and on behalf of the Company.  If an Officer whose signature is on a
Security no longer holds that office at the time the Security is  authenticated,
the Security shall nevertheless be valid.

     The Trustee,  at the expense of the Company,  may appoint an authenticating
agent  (the  "Authenticating  Agent") to  authenticate  Securities  (other  than
coupons).  The  Authenticating  Agent may authenticate  Securities  whenever the
Trustee may do so. Each  reference in this  Indenture to  authentication  by the
Trustee includes authentication by such Authenticating Agent.

     A Security  (other  than  coupons)  shall not be valid until the Trustee or
Authenticating  Agent manually signs the  certificate of  authentication  on the
Security.  The signature shall be conclusive evidence that the Security has been
authenticated under this Indenture.

     At any time and from time to time after the  execution and delivery of this
Indenture,  the Company may deliver  Securities  of any series  having  attached
thereto appropriate  coupons, if any, executed by the Company to the Trustee for
authentication  together with the applicable documents referred to below in this
Section,  and  the  Trustee  shall  thereupon   authenticate  and  deliver  such
Securities to or upon the written order of the Company.  In  authenticating  any
Securities  of a series,  the 



                                      -11-


Trustee  shall be entitled to receive prior to the first  authentication  of any
Securities of such series,  and (subject to Article 7) shall be fully  protected
in relying  upon,  unless  and until  such  documents  have been  superseded  or
revoked:

     (1) any Board Resolution and/or executed supplemental indenture referred to
  in  Sections  2.1 and 2.3 by or  pursuant  to which the forms and terms of the
  Securities of that series were established;

     (2) an Officers'  Certificate  setting forth the form or forms and terms of
  the Securities,  stating that the form or forms and terms of the Securities of
  such series have been, or will be when  established  in  accordance  with such
  procedures as shall be referred to therein,  established  in  compliance  with
  this Indenture; and

     (3) an  Opinion  of Counsel  substantially  to the effect  that the form or
  forms and terms of the  Securities  of such series have been,  or will be when
  established  in  accordance  with  such  procedures  as shall be  referred  to
  therein,   established  in  compliance   with  this  Indenture  and  that  the
  supplemental  indenture,  to the extent  applicable,  and Securities have been
  duly  authorized  and, if executed and  authenticated  in accordance  with the
  provisions  of the  Indenture  and  delivered  to  and  duly  paid  for by the
  purchasers  thereof  on the date of such  opinion,  would be  entitled  to the
  benefits of the  Indenture and would be valid and binding  obligations  of the
  Company,  enforceable  against the Company in accordance with their respective
  terms,  subject  to  bankruptcy,  insolvency,  reorganization,   receivership,
  moratorium  and other  similar laws  affecting  creditors'  rights  generally,
  general  principles  of equity,  and such other  matters as shall be specified
  therein.

     If the Company shall establish  pursuant to Section 2.3 that the Securities
of a series  or a  portion  thereof  are to be issued in the form of one or more
Registered  Global  Securities,  then the Company  shall execute and the Trustee
shall authenticate and deliver one or more Registered Global Securities that (i)
shall  represent  and shall be  denominated  in an amount equal to the aggregate
principal amount of all of the Securities of such series issued in such form and
not yet  cancelled,  (ii) shall be registered in the name of the  Depositary for
such Registered Global Security or Securities or the nominee of such Depositary,
(iii) shall be delivered by the Trustee to such  Depositary  or its custodian or
pursuant  to  such  Depositary's  instructions  and  (iv)  shall  bear a  legend
substantially  to the  following  effect:  "Unless and until it is  exchanged in
whole or in part for Securities in definitive registered form, 



                                      -12-


this Security may not be transferred  except as a whole by the Depositary to the
nominee of the Depositary or by a nominee of the Depositary to the Depositary or
another  nominee of the Depositary or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary."

     SECTION 2.3. Amount Unlimited;  Issuable in Series. The aggregate principal
amount of  Securities  which  may be  authenticated  and  delivered  under  this
Indenture is unlimited.

     The  Securities  may  be  issued  in  one  or  more  series  and  shall  be
subordinated to the Senior and  Subordinated  Debt pursuant to the provisions of
Article 11 hereof. There shall be established in or pursuant to Board Resolution
or one or more indentures  supplemental hereto, prior to the initial issuance of
Securities of any series, subject to the last sentence of this Section 2.3,

     (1)  the  designation  of  the  Securities  of  the  series,   which  shall
  distinguish  the  Securities  of the series from the  Securities  of all other
  series;

     (2) any limit upon the aggregate  principal amount of the Securities of the
  series that may be  authenticated  and delivered  under this Indenture and any
  limitation on the ability of the Company to increase such aggregate  principal
  amount after the initial issuance of the Securities of that series (except for
  Securities authenticated and delivered upon registration of transfer of, or in
  exchange for, or in lieu of, or upon  redemption  of, other  Securities of the
  series pursuant hereto);

     (3) the date or  dates on which  the  principal  of the  Securities  of the

  and (in the case of  Registered  Securities)  on which a record shall be taken
  for the determination of Holders to whom interest is payable and/or the method
  by which such rate or rates or date or dates shall be determined;

     (5) if other than as provided in Section 4.2, the place or places where the
  principal  of and any interest on  Securities  of the series shall be payable,
  any  Registered  Securities  of the series may be  surrendered  for  exchange,

                                      -13-

  the series may be so redeemed, pursuant to any sinking fund or otherwise;

     (7) the  obligation,  if any, of the  Company to redeem,  purchase or repay
  Securities of the series pursuant to any mandatory redemption, sinking fund or
  analogous  provisions  or at the option of a Holder  thereof  and the price or
  prices at which and the  period or periods  within  which and any of the terms
  and  conditions  upon  which  Securities  of the  series  shall  be  redeemed,
  purchased or repaid, in whole or in part, pursuant to such obligation;

     (8) if  other  than  denominations  of  $1,000  and any  integral  multiple

  amount of payments of principal of and/or  interest on the  Securities  of the
  series  may be  determined  with  reference  to an  index  based  on a coin or

  Securities rather than pay such additional amounts;

     (14) if the Securities of the series are to be issuable in definitive  form
  (whether upon original issue or upon exchange of a temporary  Security of such
  series)  only upon  receipt  of certain  certificates  or other  documents  or
  satisfaction  of other  conditions,  the form and terms of such  certificates,

  (including provisions permitting defeasance of less than all Securities of the
  series),  which  provisions may be in addition to, in substitution  for, or in
  modification  of (or any  combination  of the  foregoing)  the  provisions  of

                                      -15-


tion, except in the case of any Periodic Offering and except as may otherwise be
provided  by or  pursuant  to the Board  Resolution  referred to above or as set
forth in any such  indenture  supplemental  hereto.  All  Securities  of any one
series  need not be issued at the same time and may be issued from time to time,
consistent  with the terms of this  Indenture,  if so provided by or pursuant to
such Board Resolution or in any such indenture supplemental hereto and any forms
and terms of  Securities  to be issued  from time to time may be  completed  and

described in such Board Resolution or supplemental indenture.

     SECTION 2.4. Denomination and Date of Securities; Payments of Interest. The
Securities  of each  series  shall  be  issuable  as  Registered  Securities  or
Unregistered Securities in denominations  established as contemplated by Section
2.3 or, if not so  established  with  respect to  Securities  of any series,  in
denominations  of $1,000 and any integral  multiple  thereof.  The Securities of
each series  shall be  numbered,  lettered or  otherwise  distinguished  in such
manner or in accordance with such plan as the Officers of the Company  executing
the same may determine, as evidenced by their execution thereof.

     Each Security shall be dated the date of its authentication. The Securities
of each series shall bear interest, if any, from the date, and such interest and
shall be payable on the dates, established as contemplated by Section 2.3.

     The  person  in  whose  name  any  Registered  Security  of any  series  is
registered  at  the  close  of  business  on any  record  date  applicable  to a
particular  series with  respect to any  interest  payment  date for such series
shall be entitled  to receive the  interest,  if any,  payable on such  interest
payment  date  notwithstanding  any  transfer  or  exchange  of such  Registered
Security  subsequent to the record date and prior to such interest payment date,
except if and to the  extent the  Company  shall  default in the  payment of the
interest due on such  interest  payment date for such series,  in which case the
provisions  of Section  2.13 shall apply.  The term  "record  date" as used with
respect to any  interest  payment  date  (except a date for payment of defaulted
interest) for the Securities of any series shall mean the date specified as such
in the  terms  of the  Registered  Securities  of  such  series  established  as
contemplated  by  Section  2.3,  or,  if no  such  date is so  established,  the
fifteenth day next  preceding  such interest  payment date,  whether or not such
record date is a Business Day.

     SECTION 2.5.  Registrar and Paying  Agent;  Agents  Generally.  The Company
shall  maintain  an office or  agency  where  Securities  may be  presented  for
registration,  registra-



                                      -16-


tion of transfer or for exchange (the "Registrar") and an office or agency where
Securities may be presented for payment (the "Paying Agent"),  which shall be in
the Borough of  Manhattan,  The City of New York.  The  Company  shall cause the
Registrar  to  keep  a  register  of the  Registered  Securities  and  of  their
registration,  transfer and exchange (the "Security Register").  The Company may
have one or more additional Paying Agents or transfer agents with respect to any
series.

     The Company shall enter into an appropriate agency agreement with any Agent
not a party to this  Indenture.  The agreement shall implement the provisions of
this  Indenture  and the Trust  Indenture  Act that  relate to such  Agent.  The
Company shall give prompt  written notice to the Trustee of the name and address
of any Agent and any change in the name or address of an Agent.  If the  Company
fails to maintain a Registrar or Paying  Agent,  the Trustee  shall act as such.
The  Company  may  remove any Agent  upon  written  notice to such Agent and the
Trustee;  provided  that no such removal  shall become  effective  until (i) the
acceptance of an appointment by a successor  Agent to such Agent as evidenced by
an appropriate  agency agreement  entered into by the Company and such successor
Agent and delivered to the Trustee or (ii)  notification to the Trustee that the
Trustee shall serve as such Agent until the  appointment of a successor Agent in
accordance with clause (i) of this proviso.  The Company or any affiliate of the
Company may act as Paying Agent or Registrar;  provided that neither the Company
nor an affiliate of the Company shall act as Paying Agent in connection with the
defeasance of the Securities or the discharge of this Indenture under Article 8.

     The Company initially  appoints the Trustee as Registrar,  Paying Agent and
Authenticating  Agent.  If, at any time, the Trustee is not the  Registrar,  the
Registrar  shall make  available to the Trustee ten days prior to each  interest
payment date and at such other times as the Trustee may  reasonably  request the
names and addresses of the Holders as they appear in the Security Register.

     SECTION 2.6. Paying Agent to Hold Money in Trust. Not later than 10:00 a.m.
New  York  City  time on each  due  date of any  Principal  or  interest  on any
Securities, the Company shall deposit with the Paying Agent money in immediately
available funds sufficient to pay such Principal or interest.  The Company shall
require  each Paying  Agent other than the Trustee to agree in writing that such
Paying  Agent  shall  hold in  trust  for the  benefit  of the  Holders  of such
Securities  or the Trustee all money held by the Paying Agent for the payment of
Principal  of and  interest on such  Securities  and shall  promptly  notify the
Trustee of any default by the Company in making any 



                                      -17-


such  payment.  The  Company at any time may  require a Paying  Agent to pay all
money held by it to the Trustee and  account  for any funds  disbursed,  and the
Trustee may at any time during the  continuance  of any  payment  default,  upon
written  request to a Paying  Agent,  require such Paying Agent to pay all money
held by it to the Trustee and to account for any funds disbursed. Upon doing so,
the Paying Agent shall have no further  liability  for the money so paid over to
the  Trustee.  If the Company or any  affiliate  of the  Company  acts as Paying
Agent,  it will,  on or before each due date of any  Principal of or interest on
any  Securities,  segregate and hold in a separate trust fund for the benefit of
the Holders thereof a sum of money  sufficient to pay such Principal or interest
so  becoming  due  until  such sum of money  shall  be paid to such  Holders  or
otherwise  disposed of as provided in this  Indenture,  and will promptly notify
the  Trustee in writing  of its  action or  failure to act as  required  by this
Section.

     SECTION 2.7. Transfer and Exchange. Unregistered Securities (except for any
temporary  global  Unregistered  Securities)  and  coupons  (except  for coupons
attached to any temporary global Unregistered  Securities) shall be transferable
by delivery.

     At the option of the Holder  thereof,  Registered  Securities of any series
(other than a  Registered  Global  Security,  except as set forth  below) may be
exchanged for a Registered Security or Registered  Securities of such series and
tenor having authorized  denominations and an equal aggregate  principal amount,
upon  surrender of such  Registered  Securities to be exchanged at the agency of
the Company that shall be maintained for such purpose in accordance with Section
2.5  and  upon  payment,  if the  Company  shall  so  require,  of  the  charges
hereinafter  provided.  If the  Securities  of any  series  are  issued  in both
registered and unregistered  form, except as otherwise  established  pursuant to
Section 2.3, at the option of the Holder thereof, Unregistered Securities of any
series may be  exchanged  for  Registered  Securities  of such  series and tenor
having authorized  denominations and an equal aggregate  principal amount,  upon
surrender of such  Unregistered  Securities to be exchanged at the agency of the
Company that shall be  maintained  for such purpose in  accordance  with Section
4.2, with, in the case of Unregistered  Securities  that have coupons  attached,
all unmatured  coupons and all matured coupons in default thereto  appertaining,
and upon payment,  if the Company shall so require,  of the charges  hereinafter
provided. At the option of the Holder thereof, if Unregistered Securities of any
series,  maturity date, interest rate and original issue date are issued in more
than one authorized  denomination,  except as otherwise  established pursuant to
Section 2.3, such  Unregistered  Securi-



                                      -18-


ties may be  exchanged  for  Unregistered  Securities  of such  series and tenor
having authorized  denominations and an equal aggregate  principal amount,  upon
surrender of such  Unregistered  Securities to be exchanged at the agency of the
Company that shall be  maintained  for such purpose in  accordance  with Section
4.2, with, in the case of Unregistered  Securities  that have coupons  attached,
all unmatured  coupons and all matured coupons in default thereto  appertaining,
and upon payment,  if the Company shall so require,  of the charges  hereinafter
provided.  Registered  Securities  of  any  series  may  not  be  exchanged  for
Unregistered   Securities  of  such  series.  Whenever  any  Securities  are  so
surrendered  for  exchange,  the Company  shall  execute,  and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

     All Registered Securities presented for registration of transfer, exchange,
redemption or payment shall be duly endorsed by, or be  accompanied by a written
instrument or  instruments of transfer in form  satisfactory  to the Company and
the Trustee  duly  executed by, the holder or his attorney  duly  authorized  in
writing.

     The  Company may require  payment of a sum  sufficient  to cover any tax or
other governmental charge that may be imposed in connection with any exchange or
registration of transfer of Securities.  No service charge shall be made for any
such transaction.

     Notwithstanding  any other  provision of this Section 2.7, unless and until
it is  exchanged in whole or in part for  Securities  in  definitive  registered
form,  a  Registered  Global  Security  representing  all  or a  portion  of the
Securities  of a  series  may  not  be  transferred  except  as a  whole  by the
Depositary  for such series to a nominee of such  Depositary  or by a nominee of
such  Depositary to such  Depositary or another nominee of such Depositary or by
such Depositary or any such nominee to a successor Depositary for such series or
a nominee of such successor Depositary.

     If at any time the Depositary for any Registered  Global  Securities of any
series  notifies  the  Company  that it is  unwilling  or unable to  continue as
Depositary  for  such  Registered  Global  Securities  or if  at  any  time  the
Depositary for such  Registered  Global  Securities  shall no longer be eligible
under applicable law, the Company shall appoint a successor  Depositary eligible
under  applicable law with respect to such Registered  Global  Securities.  If a
successor  Depositary  eligible under applicable law for such Registered  Global
Securities  is not  appointed  by the  Company  within 90 days after the Com-



                                      -19-


pany receives such notice or becomes  aware of such  ineligibility,  the Company
will  execute,  and the  Trustee,  upon receipt of the  Company's  order for the
authentication and delivery of definitive  Registered  Securities of such series
and tenor,  will authenticate and deliver  Registered  Securities of such series
and tenor, in any authorized  denominations,  in an aggregate  principal  amount
equal to the principal amount of such Registered Global Securities,  in exchange
for such Registered Global Securities.

     The Company may at any time and in its sole  discretion  determine that any
Registered  Global  Securities  of any series shall no longer be  maintained  in
global form.  In such event the Company  will  execute,  and the  Trustee,  upon
receipt of the Company's order for the authentication and delivery of definitive
Registered  Securities of such series and tenor,  will authenticate and deliver,
Registered Securities of such series and tenor in any authorized  denominations,
in an  aggregate  principal  amount  equal  to  the  principal  amount  of  such
Registered Global Securities, in exchange for such Registered Global Securities.

     Any time the  Registered  Securities  of any  series are not in the form of
Registered  Global  Securities  pursuant to the  preceding two  paragraphs,  the
Company  agrees to supply the Trustee with a reasonable  supply of  certificated
Registered Securities without the legend required by Section 2.2 and the Trustee
agrees to hold such Registered Securities in safekeeping until authenticated and
delivered pursuant to the terms of this Indenture.

     If established  by the Company  pursuant to Section 2.3 with respect to any
Registered  Global Security,  the Depositary for such Registered Global Security
may surrender such  Registered  Global  Security in exchange in whole or in part
for Registered  Securities of the same series and tenor in definitive registered
form on such  terms  as are  acceptable  to the  Company  and  such  Depositary.
Thereupon,  the Company shall execute,  and the Trustee shall  authenticate  and
deliver, without service charge,

     (i) to the Person specified by such Depositary new Registered Securities of
  the same series and tenor,  of any  authorized  denominations  as requested by
  such  Person,  in an aggregate  principal  amount equal to and in exchange for
  such Person's beneficial interest in the Registered Global Security; and

     (ii) to such Depositary a new Registered  Global Security in a denomination
  equal  to  the  difference,  if  any,  



                                      -20-


  between the principal amount of the surrendered Registered Global Security and
  the aggregate  principal  amount of Registered  Securities  authenticated  and
  delivered pursuant to clause (i) above.

     Registered  Securities  issued in exchange for a Registered Global Security
pursuant  to this  Section  2.7 shall be  registered  in such  names and in such
authorized  denominations as the Depositary for such Registered Global Security,
pursuant to instructions from its direct or indirect  participants or otherwise,
shall  instruct  the  Trustee  or an agent of the  Company or the  Trustee.  The
Trustee or such agent shall  deliver  such  Securities  to or as directed by the
Persons in whose names such Securities are so registered.

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

     Notwithstanding  anything herein or in the forms or terms of any Securities
to the contrary, none of the Company, the Trustee or any agent of the Company or
the  Trustee  shall be  required to exchange  any  Unregistered  Security  for a
Registered  Security if such exchange would result in adverse Federal income tax
consequences to the Company (such as, for example,  the inability of the Company
to deduct from its income,  as computed  for Federal  income tax  purposes,  the
interest payable on the Unregistered  Securities)  under then applicable  United
States Federal income tax laws. The Trustee and any such agent shall be entitled
to rely on an Officers' Certificate or an Opinion of Counsel in determining such
result.

     The Registrar  shall not be required (i) to issue,  authenticate,  register
the  transfer  of or exchange  Securities  of any series for a period of 15 days
before the day of mailing of a notice of such  Securities to be redeemed  ending
at the close of  business  on the day of such  mailing or (ii) to  register  the
transfer of or exchange any Security selected for redemption in whole or in part
except the unredeemed portion of Securities redeemed in part.

     SECTION 2.8. Replacement Securities.  If a defaced or mutilated Security of
any series is surrendered to the Trustee or if a Holder claims that its Security
of any series has been lost,  destroyed or wrongfully  taken,  the Company shall
issue and the Trustee shall  authenticate a replacement  Security of such series
and  tenor  and  principal   amount  bearing  a  number  not   contemporaneously
outstanding.  If required by the Trustee 



                                      -21-


or the Company,  an indemnity  bond must be furnished  that is sufficient in the
judgment of both the Trustee and the Company to protect the Company, the Trustee
and any  Agent  from any  loss  that any of them may  suffer  if a  Security  is
replaced.  The Company may charge such Holder for its  expenses and the expenses
of the Trustee (including  without  limitation  attorneys' fees and expenses) in
replacing a Security.  In case any such mutilated,  defaced,  lost, destroyed or
wrongfully taken Security has become or is about to become due and payable,  the
Company  in its  discretion  may pay such  Security  instead  of  issuing  a new
Security in replacement thereof.

     Every replacement  Security is an additional  obligation of the Company and
shall be entitled to the benefits of this Indenture.

     To the extent  permitted by law, the  foregoing  provisions of this Section
are  exclusive  with  respect  to  the  replacement  or  payment  of  mutilated,
destroyed, lost or wrongfully taken Securities.

     SECTION 2.9. Outstanding Securities. Securities outstanding at any time are
all  Securities  that have been  authenticated  by the Trustee  except for those
cancelled by it, those delivered to it for  cancellation  and those described in
this Section as not outstanding.

     If a  Security  is  replaced  pursuant  to  Section  2.8,  it  ceases to be
outstanding  unless  and  until  the  Trustee  and  the  Company  receive  proof
satisfactory  to them  that the  replaced  Security  is held by a holder  in due
course.

     If the Paying Agent (other than the Company or an affiliate of the Company)
holds on the maturity date or any redemption  date or date for repurchase of the
Securities  money  sufficient  to pay  Securities  payable or to be  redeemed or
repurchased on that date, then on and after that date such  Securities  cease to
be outstanding and interest on them shall cease to accrue.

     A Security does not cease to be  outstanding  because the Company or one of
its affiliates  holds such  Security,  provided,  however,  that, in determining
whether  the  Holders  of the  requisite  principal  amount  of the  outstanding
Securities have given any request,  demand,  authorization,  direction,  notice,
consent or waiver hereunder, Securities owned by the Company or any affiliate of
the Company shall be disregarded and deemed not to be outstanding,  except that,
in  determining  whether the Trustee shall be protected in relying upon any such
request,  demand,  authorization,  direction,  notice,  consent or waiver,  



                                      -22-


only  Securities as to which a  Responsible  Officer of the Trustee has received
written notice to be so owned shall be so  disregarded.  Any Securities so owned
which are  pledged  by the  Company,  or by any  affiliate  of the  Company,  as
security  for  loans  or  other  obligations,  otherwise  than to  another  such
affiliate of the Company,  shall be deemed to be outstanding,  if the pledgee is
entitled  pursuant to the terms of its pledge  agreement and is free to exercise
in its or his discretion the right to vote such securities,  uncontrolled by the
Company or by any such affiliate.

     SECTION 2.10.  Temporary  Securities.  Until  definitive  Securities of any
series are ready for  delivery,  the Company  may prepare and the Trustee  shall
authenticate  temporary  Securities of such series.  Temporary Securities of any
series  shall be  substantially  in the form of  definitive  Securities  of such
series but may have  insertions,  substitutions,  omissions and other variations
determined to be appropriate by the Officers executing the temporary Securities,
as  evidenced  by their  execution of such  temporary  Securities.  If temporary
Securities  of  any  series  are  issued,  the  Company  will  cause  definitive
Securities of such series to be prepared without  unreasonable  delay. After the
preparation of definitive  Securities of any series, the temporary Securities of
such series shall be exchangeable  for definitive  Securities of such series and
tenor upon surrender of such temporary Securities at the office or agency of the
Company  designated for such purpose  pursuant to Section 4.2, without charge to
the  Holder.  Upon  surrender  for  cancellation  of any one or  more  temporary
Securities  of any  series the  Company  shall  execute  and the  Trustee  shall
authenticate  and  deliver  in  exchange  therefor  a like  principal  amount of
definitive  Securities  of such series and tenor and  authorized  denominations.
Until so exchanged,  the temporary Securities of any series shall be entitled to
the same benefits under this Indenture as definitive Securities of such series.

     SECTION  2.11.  Cancellation.  The  Company at any time may  deliver to the
Trustee for cancellation any Securities  previously  authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever,  and may
deliver to the Trustee for cancellation any Securities previously  authenticated
hereunder which the Company has not issued and sold. The Registrar, any transfer
agent  and  the  Paying  Agent  shall  forward  to the  Trustee  any  Securities
surrendered to them for transfer,  exchange or payment. The Trustee shall cancel
and  destroy all  Securities  surrendered  for  transfer,  exchange,  payment or
cancellation and shall deliver a certificate of destruction to the Company.  The
Company may not issue new  Securities to replace  Securities it has paid in full
or delivered to the Trustee for cancellation.


                                      -23-


     SECTION 2.12. CUSIP Numbers.  The Company in issuing the Securities may use
"CUSIP" and "CINS" numbers (if then generally in use), and the Trustee shall use
CUSIP numbers or CINS  numbers,  as the case may be, in notices of redemption or
exchange as a convenience to Holders and no  representation  shall be made as to
the  correctness  of such  numbers  either as  printed on the  Securities  or as
contained in any notice of redemption or exchange.

     SECTION 2.13.  Defaulted Interest.  If the Company defaults in a payment of
interest on the Securities, it shall pay, or shall deposit with the Paying Agent
money in immediately  available funds sufficient to pay, the defaulted  interest
plus (to the extent lawful) any interest  payable on the defaulted  interest (as
may be specified in the terms thereof,  established  pursuant to Section 2.3) to
the Persons who are Holders on a subsequent  special  record  date,  which shall
mean the 15th day next  preceding  the date fixed by the Company for the payment
of defaulted  interest,  whether or not such day is a Business  Day. At least 15
days before such special  record date, the Company shall mail to each Holder and
to the Trustee a notice that states the special  record  date,  the payment date
and the amount of defaulted interest to be paid.

     SECTION  2.14.  Series May Include  Tranches.  A series of  Securities  may
include  one or  more  tranches  (each a  "tranche")  of  Securities,  including
Securities issued in a Periodic  Offering.  The Securities of different tranches
may have one or more different terms, including  authentication dates and public
offering  prices,  but all the  Securities  within each such tranche  shall have
identical  terms,  including  authentication  date and  public  offering  price.
Notwithstanding any other provision of this Indenture,  with respect to Sections
2.2 (other than the fourth  paragraph  thereof) through 2.4, 2.7, 2.8, 2.10, 3.1
through 3.5,  4.2, 6.1 through  6.14,  8.1 through 8.7 and 9.2, if any series of
Securities  includes  more than one tranche,  all  provisions  of such  sections
applicable to any series of  Securities  shall be deemed  equally  applicable to
each tranche of any series of Securities in the same manner as though originally
designated a series  unless  otherwise  provided  with respect to such series or
tranche  pursuant to Section 2.3. In particular,  and without limiting the scope
of the next  preceding  sentence,  any of the  provisions of such sections which
provide for or permit  action to be taken with respect to a series of Securities
shall also be deemed to provide for and permit  such action to be taken  instead
only with respect to Securities of one or more tranches  within that series (and
such provisions shall be deemed satisfied thereby), even if no comparable action
is taken with respect to Securities in the remaining tranches of that series.


                                      -24-


                                    ARTICLE 3

                                   REDEMPTION

     SECTION 3.1. Applicability of Article. The provisions of this Article shall
be applicable to the Securities of any series which are redeemable  before their
maturity or to any sinking fund for the  retirement  of  Securities  of a series
except as otherwise  specified as  contemplated by Section 2.3 for Securities of
such series.

     SECTION  3.2.  Notice  of  Redemption;   Partial  Redemptions.   Notice  of
redemption to the Holders of Registered  Securities of any series to be redeemed
as a whole or in part at the  option of the  Company  shall be given by  mailing
notice of such redemption by first-class mail, postage prepaid, at least 30 days
and not more than 60 days prior to the date fixed for redemption to such Holders
of Registered  Securities  of such series at their last  addresses as they shall
appear  upon the  Security  Register.  Notice of  redemption  to the  Holders of
Unregistered  Securities  of any series to be redeemed as a whole or in part who
have filed  their  names and  addresses  with the  Trustee  pursuant  to Section
313(c)(2) of the Trust  Indenture  Act, shall be given by mailing notice of such
redemption,  by first class mail, postage prepaid, at least 30 days and not more
than 60 days prior to the date  fixed for  redemption,  to such  Holders at such
addresses  as were so  furnished  to the Trustee  (and,  in the case of any such
notice given by the Company,  the Trustee shall make such information  available
to the Company for such  purpose).  Notice of redemption to all other Holders of
Unregistered Securities of any series to be redeemed as a whole or in part shall
be published in an Authorized  Newspaper in The City of New York or with respect
to any Security the interest on which is based on the offered  quotations in the
interbank  Eurodollar  market for dollar deposits in an Authorized  Newspaper in
London, in each case, once in each of three successive calendar weeks, the first
publication  to be not less than 30 days nor more than 60 days prior to the date
fixed for  redemption.  Any notice  which is mailed or  published  in the manner
herein provided shall be conclusively  presumed to have been duly given, whether
or not the Holder  receives the notice.  Failure to give notice by mail,  or any
defect in the notice to the Holder of any  Security of a series  designated  for
redemption  as a  whole  or in  part  shall  not  affect  the  validity  of  the
proceedings for the redemption of any other Security of such series.

     The notice of  redemption  to each such Holder shall  specify the principal
amount of each  Security of such series 



                                      -25-


held by such Holder to be redeemed,  the CUSIP  numbers of the  Securities to be
redeemed,  the date fixed for  redemption,  the redemption  price,  the place or
places of payment,  that payment will be made upon presentation and surrender of
such Securities and, in the case of Securities with coupons attached thereto, of
all coupons  appertaining  thereto maturing after the date fixed for redemption,
that such  redemption is pursuant to the mandatory or optional  sinking fund, or
both,  if  such be the  case,  that  interest  accrued  to the  date  fixed  for
redemption  will be paid as  specified in such notice and that on and after said
date  interest  thereon or on the portions  thereof to be redeemed will cease to
accrue.  In case any  Security of a series is to be  redeemed in part only,  the
notice of redemption  shall state the portion of the principal amount thereof to
be  redeemed  and shall  state that on and after the date fixed for  redemption,
upon surrender of such Security, a new Security or Securities of such series and
tenor in  principal  amount  equal to the  unredeemed  portion  thereof  will be
issued.

     The notice of  redemption of Securities of any series to be redeemed at the
option  of the  Company  shall be  given by the  Company  or,  at the  Company's
request, by the Trustee in the name and at the expense of the Company.

     On or before 10:00 a.m. New York City time on the redemption date specified
in the notice of redemption given as provided in this Section,  the Company will
deposit  with the Trustee or with one or more Paying  Agents (or, if the Company
is acting as its own Paying  Agent,  set aside,  segregate  and hold in trust as
provided  in  Section  2.6) an  amount  of money  sufficient  to  redeem  on the
redemption  date all the  Securities of such series so called for  redemption at
the appropriate  redemption  price,  together with accrued  interest to the date
fixed for redemption. If all of the outstanding Securities of a series are to be
redeemed,  the Company will deliver to the Trustee at least 10 days prior to the
last date on which notice of redemption may be given to Holders  pursuant to the
first  paragraph  of this  Section  3.2 (or  such  shorter  period  as  shall be
acceptable  to the  Trustee)  an  Officers'  Certificate  stating  that all such
Securities are to be redeemed. If less than all the outstanding  Securities of a
series are to be  redeemed,  the Company will deliver to the Trustee at least 15
days  prior  to the last  date on which  notice  of  redemption  may be given to
Holders  pursuant to the first  paragraph  of this  Section 3.2 (or such shorter
period as shall be acceptable to the Trustee) an Officers'  Certificate  stating
the aggregate  principal amount of such Securities to be redeemed.  In case of a
redemption  at the  election  of the  Company  prior  to the  expiration  of any
restriction on such redemption,  the Company shall deliver to the Trustee, prior
to the giving of any notice of redemption  to Holders  



                                      -26-


pursuant to this Section, an Officers'  Certificate stating that such redemption
is not prohibited by such restriction.

     If less than all the Securities of a series are to be redeemed, the Trustee
shall select,  pro rata,  by lot or in such manner as it shall deem  appropriate
and  fair,  Securities  of such  series  to be  redeemed  in  whole  or in part.
Securities may be redeemed in part in multiples equal to the minimum  authorized
denomination for Securities of such series or any multiple thereof.  The Trustee
shall  promptly  notify the Company in writing of the  Securities of such series
selected  for  redemption  and,  in the case of any  Securities  of such  series
selected for partial  redemption,  the principal  amount thereof to be redeemed.
For all purposes of this Indenture,  unless the context otherwise requires,  all
provisions relating to the redemption of Securities shall relate, in the case of
any  Security  redeemed  or to be redeemed  only in part,  to the portion of the
principal amount of such Security which has been or is to be redeemed.

     SECTION 3.3.  Payment of  Securities  Called for  Redemption.  If notice of
redemption  has been given as above  provided,  the  Securities  or  portions of
Securities specified in such notice shall become due and payable on the date and
at the place stated in such notice at the applicable  redemption price, together
with interest  accrued to the date fixed for  redemption,  and on and after such
date (unless the Company shall default in the payment of such  Securities at the
redemption  price,  together with interest accrued to such date) interest on the
Securities  or portions of Securities  so called for  redemption  shall cease to
accrue, and the unmatured coupons,  if any,  appertaining  thereto shall be void
and,  except as provided in Sections 7.11 and 8.2, such  Securities  shall cease
from and after the date fixed for redemption to be entitled to any benefit under
this  Indenture,  and the Holders thereof shall have no right in respect of such
Securities  except the right to receive the redemption  price thereof and unpaid
interest to the date fixed for redemption. On presentation and surrender of such
Securities  at a place of payment  specified in said notice,  together  with all
coupons,  if any,  appertaining  thereto  maturing  after  the  date  fixed  for
redemption,  said Securities or the specified portions thereof shall be paid and
redeemed  by the  Company at the  applicable  redemption  price,  together  with
interest accrued thereon to the date fixed for redemption; provided that payment
of interest  becoming due on or prior to the date fixed for redemption  shall be
payable in the case of Securities with coupons attached thereto,  to the Holders
of the coupons for such  interest  upon  surrender  thereof,  and in the case of
Registered  Securities,  to the Holders of such Registered Securities registered
as such on the  relevant  record  date  



                                      -27-


subject to the terms and provisions of Sections 2.4 and 2.13 hereof.

     If any Security  called for redemption  shall not be so paid upon surrender
thereof for redemption,  the principal  shall,  until paid or duly provided for,
bear  interest  from the date fixed for  redemption  at the rate of  interest or
Yield to Maturity (in the case of an Original Issue Discount  Security) borne by
such Security.

     If any Security with coupons attached thereto is surrendered for redemption
and is not accompanied by all appurtenant  coupons maturing after the date fixed
for redemption, the surrender of such missing coupon or coupons may be waived by
the Company and the Trustee, if there be furnished to each of them such security
or indemnity as they may require to save each of them harmless.

     Upon  presentation of any Security of any series redeemed in part only, the
Company shall execute and the Trustee  shall  authenticate  and deliver to or on
the order of the Holder thereof,  at the expense of the Company,  a new Security
or Securities of such series and tenor (with any unmatured coupons attached), of
authorized denominations, in principal amount equal to the unredeemed portion of
the Security so presented.

     SECTION 3.4. Exclusion of Certain Securities from Eligibility for Selection
for Redemption.  Securities shall be excluded from eligibility for selection for
redemption if they are identified by registration  and  certificate  number in a
written  statement signed by an authorized  officer of the Company and delivered
to the  Trustee  at least 40 days  prior to the  last  date on which  notice  of
redemption  may be given as being owned of record and  beneficially  by, and not
pledged or hypothecated by, either (a) the Company or (b) an entity specifically
identified in such written  statement as directly or indirectly  controlling  or
controlled by or under direct or indirect common control with the Company.

     SECTION 3.5.  Mandatory and Optional  Sinking Funds.  The minimum amount of
any sinking fund payment  provided for by the terms of  Securities of any series
is herein referred to as a "mandatory sinking fund payment",  and any payment in
excess of such minimum amount provided for by the terms of the Securities of any
series is herein referred to as an "optional sinking fund payment".  The date on
which a sinking fund payment is to be made is herein referred to as the "sinking
fund payment date".

                                      -28-


     In lieu of making all or any part of any  mandatory  sinking  fund  payment
with respect to any series of Securities in cash,  the Company may at its option
(a) deliver to the Trustee  Securities of such series  theretofore  purchased or
otherwise  acquired  (except  through a mandatory  sinking fund  payment) by the
Company or receive  credit for  Securities  of such  series (not  previously  so
credited)  theretofore  purchased or otherwise acquired (except as aforesaid) by
the Company and  delivered to the Trustee for  cancellation  pursuant to Section
2.11, (b) receive credit for optional  sinking fund payments (not  previously so
credited) made pursuant to this Section, or (c) receive credit for Securities of
such series (not  previously  so credited)  redeemed by the Company  through any
optional  sinking fund  payment.  Securities  so delivered or credited  shall be
received  or  credited  by the  Trustee at the  sinking  fund  redemption  price
specified in such Securities.

     On or before the sixtieth day next preceding each sinking fund payment date
for any series,  or such shorter  period as shall be  acceptable to the Trustee,
the Company will deliver to the Trustee an Officers'  Certificate (a) specifying
the portion of the mandatory  sinking fund payment to be satisfied by payment of
cash and the portion to be satisfied by credit of specified  Securities  of such
series and the basis for such  credit,  (b) stating  that none of the  specified
Securities of such series has theretofore been so credited,  (c) stating that no
defaults in the payment of  interest or Events of Default  with  respect to such
series have  occurred  (which have not been waived or cured) and are  continuing
and (d) stating whether or not the Company intends to exercise its right to make
an  optional  sinking  fund  payment  with  respect to such  series  and, if so,
specifying  the amount of such  optional  sinking fund payment which the Company
intends to pay on or before the next  succeeding  sinking fund payment date. Any
Securities  of such series to be credited  and  required to be  delivered to the
Trustee in order for the Company to be entitled to credit  therefor as aforesaid
which have not theretofore  been delivered to the Trustee shall be delivered for
cancellation  pursuant  to  Section  2.11 to the  Trustee  with  such  Officers'
Certificate  (or reasonably  promptly  thereafter if acceptable to the Trustee).
Such  Officers'  Certificate  shall be  irrevocable  and upon its receipt by the
Trustee the Company shall become unconditionally  obligated to make all the cash
payments or delivery of securities therein referred to, if any, on or before the
next succeeding sinking fund payment date. Failure of the Company,  on or before
any such  sixtieth day, to deliver such  Officer's  Certificate  and  Securities
specified in this  paragraph,  if any,  shall not constitute a default but shall
constitute,  on and as of such date, the irrevocable election of the Company (i)
that  the  mandatory  sinking  fund  payment  for  such  series  due on the 



                                      -29-


next succeeding sinking fund payment date shall be paid entirely in cash without
the option to deliver or credit Securities of such series in respect thereof and
(ii) that the Company will make no optional sinking fund payment with respect to
such series as provided in this Section.

     If the sinking fund payment or payments  (mandatory or optional or both) to
be made in cash on the next succeeding sinking fund payment date plus any unused
balance of any preceding sinking fund payments made in cash shall exceed $50,000
(or a lesser sum if the Company shall so request with respect to the  Securities
of any series),  such cash shall be applied on the next succeeding  sinking fund
payment date to the  redemption of Securities of such series at the sinking fund
redemption  price  thereof  together with accrued  interest  thereon to the date
fixed for  redemption.  If such amount  shall be $50,000 (or such lesser sum) or
less and the Company makes no such request then it shall be carried over until a
sum in excess of $50,000 (or such lesser sum) is  available.  The Trustee  shall
select,  in the manner  provided in Section 3.2, for  redemption on such sinking
fund payment date a sufficient  principal amount of Securities of such series to
absorb said cash, as nearly as may be, and shall (if requested in writing by the
Company)  inform the  Company of the serial  numbers of the  Securities  of such
series (or portions  thereof) so  selected.  Securities  shall be excluded  from
eligibility  for  redemption  under  this  Section  if they  are  identified  by
registration and certificate number in an Officers' Certificate delivered to the
Trustee at least 60 days prior to the sinking  fund  payment date as being owned
of record and beneficially by, and not pledged or hypothecated by either (a) the
Company or (b) an entity specifically  identified in such Officers'  Certificate
as  directly or  indirectly  controlling  or  controlled  by or under  direct or
indirect  common control with the Company.  The Trustee,  in the name and at the
expense of the  Company (or the  Company,  if it shall so request the Trustee in
writing) shall cause notice of redemption of the Securities of such series to be
given in  substantially  the manner provided in Section 3.2 (and with the effect
provided in Section 3.3) for the redemption of Securities of such series in part
at the option of the  Company.  The amount of any sinking  fund  payments not so
applied or allocated to the  redemption  of  Securities  of such series shall be
added to the next cash sinking fund payment for such series and,  together  with
such  payment,  shall be  applied  in  accordance  with the  provisions  of this
Section. Any and all sinking fund moneys held on the stated maturity date of the
Securities  of  any  particular   series  (or  earlier,   if  such  maturity  is
accelerated),  which are not held for the payment or  redemption  of  particular
Securities  of such series  shall be applied,  together  with other  moneys,  if
necessary,  sufficient for the purpose,  to the payment of the 



                                      -30-


Principal of, and interest on, the Securities of such series at maturity.

     On or before  10:00 a.m.  New York City time on each  sinking  fund payment
date,  the Company shall pay to the Trustee in cash or shall  otherwise  provide
for the  payment of all  interest  accrued to the date fixed for  redemption  on
Securities to be redeemed on the next following sinking fund payment date.

     The Trustee  shall not redeem or cause to be redeemed any  Securities  of a
series with sinking fund moneys or mail any notice of  redemption  of Securities
of such series by  operation  of the sinking  fund during the  continuance  of a
Default in payment of  interest  on such  Securities  or of any Event of Default
except that,  where the mailing of notice of redemption of any Securities  shall
theretofore  have been made,  the Trustee  shall  redeem or cause to be redeemed
such  Securities,  provided  that it shall have  received from the Company a sum
sufficient for such redemption.  Except as aforesaid,  any moneys in the sinking
fund for such series at the time when any such Default or Event of Default shall
occur, and any moneys thereafter paid into the sinking fund,  shall,  during the
continuance  of such  default  or Event  of  Default,  be  deemed  to have  been
collected  under Article 6 and held for the payment of all such  Securities.  In
case such Event of Default  shall have been waived as provided in Section 6.4 or
the Default  cured on or before the  sixtieth  day  preceding  the sinking  fund
payment date in any year,  such moneys shall  thereafter  be applied on the next
succeeding  sinking  fund payment  date in  accordance  with this Section to the
redemption of such Securities.

                                    ARTICLE 4

                                    COVENANTS

     SECTION 4.1. Payment of Securities.  The Company shall pay the Principal of
and interest on the  Securities  on the dates and in the manner  provided in the
Securities and this Indenture.  The interest on Securities with coupons attached
(together  with any  additional  amounts  payable  pursuant to the terms of such
Securities) shall be payable only upon presentation and surrender of the several
coupons  for  such  interest  installments  as are  evidenced  thereby  as  they
severally  mature.  The  interest  on  any  temporary  Unregistered   Securities
(together  with any  additional  amounts  payable  pursuant to the terms of such
Securities)  shall be paid,  as to the  installments  of interest  evidenced  by
coupons attached thereto,  if any, only upon presentation and surrender thereof,
and, as to the other in-



                                      -31-


stallments of interest,  if any,  only upon  presentation  of such  Unregistered
Securities for notation thereon of the payment of such interest. The interest on
Registered  Securities (together with any additional amounts payable pursuant to
the terms of such  Securities)  shall be payable only to the Holders thereof and
at the option of the  Company  may be paid by mailing  checks for such  interest
payable to or upon the written order of such Holders at their last  addresses as
they appear on the Security Register of the Company.

     Notwithstanding  any provisions of this Indenture and the Securities of any
series to the contrary,  if the Company and a Holder of any Registered  Security
so agree,  payments of interest  on, and any portion of the  Principal  of, such
Holder's  Registered Security (other than interest payable at maturity or on any
redemption or repayment date or the final payment of Principal on such Security)
shall be made by the Paying Agent,  upon receipt from the Company of immediately
available  funds by 11:00 A.M., New York City time (or such other time as may be
agreed to between the Company and the Paying  Agent),  directly to the Holder of
such  Security (by Federal  funds wire  transfer or otherwise) if the Holder has
delivered written instructions to the Trustee 15 days prior to such payment date
requesting that such payment will be so made and designating the bank account to
which such  payments  shall be so made and in the case of payments of Principal,
surrenders  the same to the  Trustee in exchange  for a Security  or  Securities
aggregating the same principal amount as the unredeemed  principal amount of the
Securities  surrendered.  The  Trustee  shall  be  entitled  to rely on the last
instruction  delivered  by the Holder  pursuant to this Section 4.1 unless a new
instruction  is  delivered  15 days prior to a payment  date.  The Company  will
indemnify and hold each of the Trustee and any Paying Agent harmless against any
loss, liability or expense (including attorneys' fees) resulting from any act or
omission to act on the part of the Company or any such Holder in connection with
any such  agreement  or from  making  any  payment in  accordance  with any such
agreement.

     The  Company  shall pay  interest  on overdue  Principal,  and  interest on
overdue  installments of interest,  to the extent lawful,  at the rate per annum
specified in the Securities.

     SECTION 4.2.  Maintenance of Office or Agency. The Company will maintain in
the  Borough  of  Manhattan,  The City of New York,  an  office or agency  where
Securities may be surrendered  for  registration  of transfer or exchange or for
presentation for payment and where notices and demands to or upon the Company in
respect of the Securities  and this Indenture may be served.  The Company hereby
initially  designates  the  office of the  Trustee,  located  in the  Borough of
Manhattan,  The City of 


                                      -32-


New York, as such office or agency of the Company.  The Company will give prompt
written  notice to the Trustee of the location,  and any change in the location,
of such office or agency.  If at any time the Company shall fail to maintain any
such  required  office or agency or shall fail to furnish the  Trustee  with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the address of the Trustee set forth in Section 10.2.

     The Company will maintain one or more agencies in a city or cities  located
outside  the  United  States  (including  any city in which  such an  agency  is
required  to be  maintained  under the rules of any stock  exchange on which the
Securities of any series are listed) where the Unregistered Securities,  if any,
of each series and coupons,  if any,  appertaining  thereto may be presented for
payment.  No payment on any  Unregistered  Security  or coupon will be made upon
presentation of such Unregistered Security or coupon at an agency of the Company
within the United  States nor will any payment be made by transfer to an account
in,  or by  mail to an  address  in,  the  United  States  unless,  pursuant  to
applicable  United States laws and regulations then in effect,  such payment can
be made without  adverse tax  consequences to the Company.  Notwithstanding  the
foregoing,  if full payment in United States Dollars  ("Dollars") at each agency
maintained  by the  Company  outside  the  United  States  for  payment  on such
Unregistered   Securities  or  coupons   appertaining   thereto  is  illegal  or
effectively  precluded  by  exchange  controls  or other  similar  restrictions,
payments  in  Dollars of  Unregistered  Securities  of any  series  and  coupons
appertaining  thereto  which are  payable in Dollars may be made at an agency of
the Company maintained in the Borough of Manhattan, The City of New York.

     The Company may also from time to time  designate one or more other offices
or agencies  where the  Securities of any series may be presented or surrendered
for  any  or  all  such  purposes  and  may  from  time  to  time  rescind  such
designations;  provided  that no such  designation  or  rescission  shall in any
manner  relieve the Company of its obligation to maintain an office or agency in
the Borough of Manhattan,  The City of New York for such  purposes.  The Company
will give  prompt  written  notice to the  Trustee  of any such  designation  or
rescission and of any change in the location of any such other office or agency.

     SECTION 4.3.  Securityholders'  Lists. The Company will furnish or cause to
be  furnished  to the Trustee a list in such form as the Trustee may  reasonably
require of the names and addresses of the holders of the Securities  pursuant to
Section 312 of the Trust Indenture Act of 1939 (a)  semi-annually  not more than
15 days after each record date for the  payment of  


                                      -33-


semi-annual  interest on the Securities,  as hereinabove  specified,  as of such
record date,  and (b) at such other times as the Trustee may request in writing,
within thirty days after receipt by the Company of any such request as of a date
not more than 15 days prior to the time such information is furnished.

     SECTION  4.4.  Certificate  to  Trustee.  The Company  will  furnish to the
Trustee annually, on or before a date not more than four months after the end of
its  fiscal  year  (which,  on the date  hereof,  is a calendar  year),  a brief
certificate  (which need not contain the  statements  required by Section  10.4)
from its principal  executive,  financial or accounting officer as to his or her
knowledge of the  compliance  of the Company with all  conditions  and covenants
under this  Indenture  (such  compliance to be determined  without regard to any
period of grace or requirement of notice  provided under this  Indenture)  which
certificate shall comply with the requirements of the Trust Indenture Act.

     SECTION 4.5. Reports by the Company. The Company covenants to file with the
Trustee,  within 15 days after the Company is required to file the same with the
Commission, copies of the annual reports and of the information,  documents, and
other  reports  which the Company  may be  required to file with the  Commission
pursuant to Section 13 or Section 15(d) of the Exchange Act.

                                    ARTICLE 5

                              SUCCESSOR CORPORATION

     SECTION 5.1. When Company May Merge, Etc. The Company shall not consolidate
with, merge with or into, or sell, convey,  transfer, lease or otherwise dispose
of all or  substantially  all of its  property  and  assets (as an  entirety  or
substantially  as  an  entirety  in  one  transaction  or a  series  of  related
transactions) to, any Person (other than a consolidation  with or merger with or
into a Subsidiary or a sale, conveyance, transfer, lease or other disposition to
a  Subsidiary)  or permit any Person to merge  with or into the  Company  unless
either  (x) the  Company  shall be the  continuing  Person or (y) the Person (if
other than the Company) formed by such  consolidation  or into which the Company
is merged or to which  properties  and assets of the Company  shall be a solvent
corporation  organized and validly  existing under the laws of the United States
of  America  or any  jurisdiction  thereof  and  shall  expressly  assume,  by a
supplemental  indenture,  executed  and  delivered  to the  

                                      -34-


Trustee,  all of the  obligations  of the Company on all of the  Securities  and
under this  Indenture and the Company shall have delivered to the Trustee (A) an
Opinion of Counsel stating that such consolidation,  merger or transfer and such
supplemental  indenture  complies with this  provision  and that all  conditions
precedent  provided for herein relating to such  transaction  have been complied
with and that such  supplemental  indenture  constitutes  the  legal,  valid and
binding  obligation of the Company or such  successor  enforceable  against such
entity in accordance with its terms,  subject to customary exceptions and (B) an
Officers' Certificate to the effect that immediately after giving effect to such
transaction, no Default shall have occurred and be continuing.

     SECTION 5.2.  Successor  Substituted.  Upon any consolidation or merger, or
any  sale,  conveyance,   transfer,   lease  or  other  disposition  of  all  or
substantially  all of the property and assets of the Company in accordance  with
Section 5.1 of this Indenture, the successor Person formed by such consolidation
or into which the Company is merged or to which such sale, conveyance, transfer,
lease or other disposition is made shall succeed to, and be substituted for, and
may exercise every right and power of, the Company under this Indenture with the
same effect as if such successor Person had been named as the Company herein.

                                    ARTICLE 6

                              DEFAULT AND REMEDIES

     SECTION  6.1.  Events of Default.  An "Event of  Default"  shall occur with
respect to the Securities of any series if:

     (a) the Company defaults in the payment of the Principal of any Security of
  such  series  when  the  same  becomes  due  and  payable  at  maturity,  upon
  acceleration,  redemption or mandatory repurchase, including as a sinking fund
  installment, or otherwise;

     (b) the Company defaults in the payment of interest on any Security of such
  series when the same becomes due and payable, and such default continues for a
  period of 30 days;

     (c) the  Company  defaults  in the  performance  of or  breaches  any other
  covenant or  agreement  of the Company in this  Indenture  with respect to any
  Security of such series 



                                      -35-


  or in the Securities of such series and such default or breach continues for a
  period of 60  consecutive  days  after  written  notice to the  Company by the
  Trustee or to the  Company  and the  Trustee by the  Holders of 25% or more in
  aggregate principal amount of the Securities of all series affected thereby;

     (d) a court having  jurisdiction  in the premises  enters a decree or order
  for relief in respect of the Company or any of its Material Subsidiaries in an
  involuntary case under any applicable bankruptcy,  insolvency or other similar
  law  now or  hereafter  in  effect,  or  appointing  a  receiver,  liquidator,
  assignee,  custodian, trustee, sequestrator or similar official of the Company
  or any of its Material  Subsidiaries  or for all or  substantially  all of the
  property  and assets of the  Company or any of its  Material  Subsidiaries  or
  ordering the winding-up or liquidation of the affairs of the Company or any of
  its  Material  Subsidiaries,  and,  in each case,  such  decree or order shall
  remain unstayed and in effect for a period of 60 consecutive days;

     (e)  the  Company  or any of its  Material  Subsidiaries  (A)  commences  a
  voluntary  case under any applicable  bankruptcy,  insolvency or other similar
  law now or  hereafter  in  effect,  or  consents  to the entry of an order for
  relief  in an  involuntary  case  under  any such  law,  (B)  consents  to the
  appointment  of or taking  possession  by a  receiver,  liquidator,  assignee,
  custodian,  trustee, sequestrator or similar official of the Company or any of
  its Material  Subsidiaries or for all or substantially all of the property and
  assets of the Company or any of its Material  Subsidiaries  or (C) effects any
  general assignment for the benefit of creditors; or

     (f) any other  Event of Default  established  pursuant  to Section 2.3 with
  respect to the Securities of such series occurs.

     SECTION  6.2.  Acceleration.  (a) If an  Event  of  Default  other  than as
described in clauses (d) or (e) of Section 6.1 with respect to the Securities of
any series then  outstanding  occurs and is  continuing,  then,  and in each and
every such case,  except for any series of  Securities  the  principal  of which
shall have already become due and payable,  either the Trustee or the Holders of
not less than 25% in aggregate  principal  amount of the  Securities of any such
affected  series  then  outstanding  hereunder  (each such  series  treated as a
separate class) by notice in writing to the Company (and to the Trustee if given
by Securityholders), may declare the entire Principal



                                      -36-


(or,  if  the  Securities  of  any  such  series  are  Original  Issue  Discount
Securities,  such  portion of the  principal  amount as may be  specified in the
terms of such series  established  pursuant to Section 2.3) of all Securities of
such affected series,  and the interest  accrued thereon,  if any, to be due and
payable  immediately,  and upon  any such  declaration  the  same  shall  become
immediately due and payable.

     (b) If an Event of Default  described  in clause (d) or (e) of Section  6.1
occurs and is continuing,  then the Principal  amount (or, if any Securities are
Original  Issue  Discount  Securities,  such portion of the  principal as may be
specified in the terms thereof  established  pursuant to Section 2.3) of all the
Securities then outstanding and interest  accrued thereon,  if any, shall be and
become immediately due and payable,  subject to the prior payment in full of all
Senior and Subordinated  Debt,  without any notice or other action by any Holder
or the Trustee, to the full extent permitted by applicable law.

     The foregoing provisions, however, are subject to the condition that if, at
any time after the principal  (or, if the Securities are Original Issue Discount
Securities,  such  portion of the  principal  as may be  specified  in the terms
thereof established pursuant to Section 2.3) of the Securities of any series (or
of all the  Securities,  as the case may be) shall have been so declared due and
payable,  and before any  judgment  or decree for the  payment of the moneys due
shall have been obtained or entered as hereinafter  provided,  the Company shall
pay or shall  deposit  with the  Trustee  a sum  sufficient  to pay all  matured
installments  of interest upon all the Securities of each such series (or of all
the Securities,  as the case may be) and the principal of any and all Securities
of each such series (or of all the  Securities,  as the case may be) which shall
have  become  due  otherwise  than by  acceleration  (with  interest  upon  such
principal and, to the extent that payment of such interest is enforceable  under
applicable  law, on overdue  installments  of interest,  at the same rate as the
rate of interest or Yield to Maturity  (in the case of Original  Issue  Discount
Securities)  specified in the Securities of each such series to the date of such
payment or deposit) and such amount as shall be  sufficient to cover all amounts
owing the Trustee  under Section 7.7, and if any and all Events of Default under
the Indenture,  other than the non-payment of the principal of Securities  which
shall  have  become  due by  acceleration,  shall  have  been  cured,  waived or
otherwise  remedied as provided herein,  then and in every such case the Holders
of a  majority  in  aggregate  principal  amount  of all  the  then  outstanding
Securities  of all such  series that have been  accelerated  (voting as a single
class),  by written  notice to the  Company  and to the  Trustee,  may waive all


                                      -37-


defaults with respect to all such series (or with respect to all the Securities,
as the case may be) and rescind and annul such declaration and its consequences,
but no such waiver or rescission  and annulment  shall extend to or shall affect
any subsequent default or shall impair any right consequent thereon.

     For all purposes under this Indenture, if a portion of the principal of any
Original Issue Discount  Securities shall have been accelerated and declared due
and  payable  pursuant  to the  provisions  hereof,  then,  from and after  such
declaration,  unless such  declaration  has been  rescinded  and  annulled,  the
principal amount of such Original Issue Discount Securities shall be deemed, for
all purposes hereunder,  to be such portion of the principal thereof as shall be
due and payable as a result of such acceleration, and payment of such portion of
the  principal  thereof  as  shall  be due  and  payable  as a  result  of  such
acceleration,  together  with  interest,  if any,  thereon and all other amounts
owing  thereunder,  shall  constitute  payment  in full of such  Original  Issue
Discount Securities.

     SECTION 6.3. Other  Remedies.  If a payment  default or an Event of Default
with  respect to the  Securities  of any series  occurs and is  continuing,  the
Trustee  may  pursue,  in its own name or as trustee of an  express  trust,  any
available  remedy by  proceeding  at law or in equity to collect  the payment of
principal  of and  interest on the  Securities  of such series or to enforce the
performance of any provision of the Securities of such series or this Indenture.

     The Trustee may  maintain a  proceeding  even if it does not possess any of
the Securities or does not produce any of them in the proceeding.

     SECTION 6.4. Waiver of Past Defaults. Subject to Sections 6.2, 6.7 and 9.2,
the Holders of at least a majority in  principal  amount (or, if the  Securities
are Original Issue Discount Securities, such portion of the principal as is then
accelerable  under  Section  6.2) of the  outstanding  Securities  of all series
affected  (voting as a single  class),  by notice to the  Trustee,  may waive an
existing  Default or Event of Default  with  respect to the  Securities  of such
series and its consequences,  except a Default in the payment of Principal of or
interest on any Security as specified in clauses (a) or (b) of Section 6.1 or in
respect of a covenant or provision of this Indenture which cannot be modified or
amended without the consent of the Holder of each outstanding Security affected.
Upon any such  waiver,  such  Default  shall  cease to  exist,  and any Event of
Default with respect to the Securities of such series 




                                      -38-


arising  therefrom shall be deemed to have been cured, for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or
Event of Default or impair any right consequent thereto.

     SECTION 6.5. Control by Majority.  Subject to Sections 7.1 and 7.2(v),  the
Holders  of at least a  majority  in  aggregate  principal  amount  (or,  if any

Securities  of such  series by this  Indenture;  provided,  that the Trustee may
refuse to follow any direction that conflicts with law or this  Indenture,  that
may involve the Trustee in personal  liability or that the Trustee determines in
good faith may be unduly prejudicial to the rights of Holders not joining in the
giving of such direction;  and provided,  further, that the Trustee may take any
other  action  it deems  proper  that is not  inconsistent  with any  directions
received from Holders of Securities pursuant to this Section 6.5.

     (i) such Holder has  previously  given to the Trustee  written  notice of a
  continuing Event of Default with respect to the Securities of such series;

     (ii)  the  Holders  of at  least  25%  in  aggregate  principal  amount  of
  outstanding  Securities  of all such series  affected  shall have made written
  request to the Trustee to  institute  proceedings  in respect of such Event of
  Default in its own name as Trustee hereunder;

     (iii) such Holder or Holders have offered and, if  requested,  provided the

                                      -39-


     (v) during  such  60-day  period,  the  Holders  of at least a majority  in
  aggregate principal amount of the outstanding  Securities of all such affected
  series have not given the Trustee a direction that is  inconsistent  with such
  written request.

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

     SECTION  6.7.  Rights of Holders to Receive  Payment.  Notwithstanding  any
other  provision  of this  Indenture,  the right of any Holder of a Security  to
receive payment of Principal of or interest,  if any, on such Holder's  Security

suit for the enforcement of any such payment on or after such respective  dates,
shall not be impaired or affected without the consent of such Holder.

     SECTION  6.8.  Collection  Suit by  Trustee.  If an Event of  Default  with
respect to the  Securities  of any series in payment of  Principal  or  interest
specified  in clause (a) or (b) of Section  6.1  occurs and is  continuing,  the

Securities) of Principal of, and accrued interest  remaining unpaid on, together

case of Original Issue Discount  Securities)  specified in such Securities,  and
such  further  amount  as shall be  sufficient  to cover all  amounts  owing the
Trustee under Section 7.7.

     SECTION  6.9.  Trustee May File Proofs of Claim.  The Trustee may file such
proofs of claim and other  papers or  documents as may be necessary or advisable
in order to have the claims of the Trustee  (including any claim for amounts due

to, or accept or adopt on  behalf  of any  Holder,  any plan of  reorganization,
arrangement, adjustment or composition affecting the Securities or the rights of
any Holder thereof,  or to authorize the Trustee to vote in respect of the claim
of any Holder in any such proceeding.

  applicable  to the  Securities  of such series in respect of which moneys have
  been collected;

     SECOND:  In case the principal of the  Securities of such series in respect
  of which moneys have been collected  shall not have become and be then due and
  payable,  to the  payment of  interest  on the  Securities  of such  series in
  default in the order of the  maturity of the  installments  of such  interest,
  with  interest  (to the extent that such  interest  has been  collected by the
  Trustee)  upon the  overdue  installments  of interest at the same rate as the
  rate of interest or Yield to Maturity (in the case of Original  Issue Discount
  Securities) specified in such Securities,  such payments to be made ratably to
  the persons entitled thereto, without discrimination or preference;

  rate of interest or Yield to Maturity (in the case of Original  Issue Discount
  Securities)  specified  in 



                                      -41-

  to pay in full the whole amount so due and unpaid upon the  Securities of such
  series,  then to the  payment  of such  Principal  and  interest  or  Yield to
  Maturity,  without  preference or priority of Principal over interest or Yield
  to Maturity,  or of interest or Yield to Maturity  over  Principal,  or of any
  installment  of interest  over any other  installment  of interest,  or of any
  Security of such series over any other Security of such series, ratably to the
  aggregate  of such  Principal  and  accrued  and unpaid  interest  or Yield to
  Maturity; and

     FOURTH:  To the  payment of the  remainder,  if any,  to the Company or any
  other person lawfully entitled thereto.

     SECTION 6.11.  Restoration  of Rights and  Remedies.  If the Trustee or any
Holder has  instituted  any proceeding to enforce any right or remedy under this
Indenture and such proceeding has been discontinued or abandoned for any reason,
or has been determined  adversely to the Trustee or to such Holder, then, and in
every such case,  subject to any determination in such proceeding,  the Company,
the  Trustee  and the  Holders  shall  be  restored  to their  former  positions
hereunder and thereafter all rights and remedies of the Company, Trustee and the
Holders shall continue as though no such proceeding had been instituted.

     SECTION 6.12. Undertaking for Costs. In any suit for the enforcement of any
right or remedy under this  Indenture or in any suit against the Trustee for any
action  taken or  omitted  by it as  Trustee,  in either  case in respect to the
Securities  of any series,  a court may require any party  litigant in such suit
(other than the  Trustee) to file an  undertaking  to pay the costs of the suit,
and the court may assess reasonable costs, including reasonable attorneys' fees,
against  any party  litigant  (other  than the  Trustee)  in the suit having due
regard to the merits and good faith of the claims or defenses  made by the party
litigant.  This  Section  6.12 does not apply to a suit by a Holder  pursuant to
Section  6.7 or a suit by  Holders of more than 10% in  principal  amount of the
outstanding Securities of such series.

     SECTION 6.13. Rights and Remedies Cumulative.  Except as otherwise provided
with respect to the  replacement  or payment of  mutilated,  destroyed,  lost or
wrongfully  taken Securities in Section 2.8, no right or remedy herein conferred
upon or reserved to the Trustee or to the Holders is intended to be exclusive of
any other  right or  remedy,  and every  right and remedy  shall,  to the extent
permitted by law, be cumulative  and in addition to every other right and remedy
given  hereunder or 



                                      -42-


now or hereafter  existing at law or in equity or  otherwise.  The  assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

     SECTION  6.14.  Delay or Omission  Not Waiver.  No delay or omission of the
Trustee or of any Holder to exercise any right or remedy accruing upon any Event
of Default  shall impair any such right or remedy or  constitute a waiver of any
such Event of Default or an acquiescence  therein.  Every right and remedy given
by this  Article 6 or by law to the Trustee or to the  Holders may be  exercised
from time to time, and as often as may be deemed expedient, by the Trustee or by
the Holders, as the case may be.

                                    ARTICLE 7

                                     TRUSTEE

     SECTION 7.1. General.  The duties and responsibilities of the Trustee shall
be  as  provided  by  the  Trust   Indenture   Act  and  as  set  forth  herein.
Notwithstanding the foregoing,  no provision of this Indenture shall require the
Trustee  to  expend  or risk its own  funds or  otherwise  incur  any  financial
liability in the performance of any of its duties hereunder,  or in the exercise
of any of its rights or powers, unless it receives indemnity  satisfactory to it
against any loss,  liability  or expense.  Whether or not therein  expressly  so
provided, every provision of this Indenture relating to the conduct or affecting
the liability of or affording  protection to the Trustee shall be subject to the
provisions of this Article 7.

     SECTION 7.2.  Certain  Rights of Trustee.  Subject to Trust  Indenture  Act
Sections 315(a) through (d):

     (i) the Trustee  may rely and shall be  protected  in acting or  refraining
  from acting upon any resolution,  certificate,  Officers' Certificate, Opinion
  of Counsel (or both), statement, instrument, opinion, report, notice, request,
  direction,   consent,   order,  bond,  debenture,   note,  other  evidence  of
  indebtedness  or other paper or  document  believed by it to be genuine and to
  have been signed or  presented  by the proper  person or persons.  The Trustee
  need not  investigate  any fact or  matter  stated  in the  document,  but the
  Trustee,  in its discretion,  may make such further  inquiry or  investigation
  into such facts or matters as it may see fit;

                                      -43-



     (ii) before the Trustee  acts or refrains  from  acting,  it may require an
  Officers'  Certificate  and/or an Opinion of Counsel,  which shall  conform to
  Section 10.4. The Trustee shall not be liable for any action it takes or omits
  to take in good faith in reliance on such  certificate or opinion.  Subject to
  Sections  7.1 and 7.2,  whenever in the  administration  of the trusts of this
  Indenture  the Trustee  shall deem it necessary or desirable  that a matter be
  proved or  established  prior to taking or  suffering  or omitting  any action
  hereunder,  such matter  (unless other  evidence in respect  thereof be herein
  specifically prescribed) may, in the absence of negligence or bad faith on the
  part of the Trustee, be deemed to be conclusively proved and established by an
  Officers' Certificate  delivered to the Trustee, and such certificate,  in the
  absence of negligence  or bad faith on the part of the Trustee,  shall be full
  warrant to the Trustee for any action  taken,  suffered or omitted by it under
  the provisions of this Indenture upon the faith thereof;

     (iii) the Trustee may act through its attorneys and agents not regularly in
  its employ and shall not be  responsible  for the  misconduct or negligence of
  any agent or attorney appointed with due care;

     (iv) any  request,  direction,  order or  demand of the  Company  mentioned
  herein shall be  sufficiently  evidenced by an Officers'  Certificate  (unless
  other evidence in respect thereof be herein specifically prescribed);  and any
  Board  Resolution may be evidenced to the Trustee by a copy thereof  certified
  by the Secretary or an Assistant Secretary of the Company;

     (v) the Trustee  shall be under no obligation to exercise any of the rights
  or powers vested in it by this Indenture at the request, order or direction of
  any of the  Holders,  unless such  Holders  shall have  offered to the Trustee
  reasonable  security or indemnity against the costs,  expenses and liabilities
  that might be incurred by it in compliance with such request or direction;

     (vi) the  Trustee  shall not be liable  for any action it takes or omits to
  take in good faith that it believes to be  authorized  or within its rights or
  powers  or for any  action  it takes or omits to take in  accordance  with the
  direction of the Holders in accordance  with Section 6.5 relating to the time,
  method and place of conducting any proceeding for any remedy  available to the
  Trustee,  or exercising any trust or power  conferred upon the Trustee,  under
  this Indenture;



                                      -44-



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

     (viii) prior to the  occurrence of an Event of Default  hereunder and after
  the curing or waiving of all Events of Default, the Trustee shall not be bound
  to make any investigation  into the facts or matters stated in any resolution,
  certificate,  Officers'  Certificate,  Opinion of Counsel,  Board  Resolution,
  statement,  instrument,  opinion,  report, notice,  request,  consent,  order,
  approval,  appraisal,  bond, debenture, note, coupon, security, or other paper
  or document  unless  requested  in writing so to do by the Holders of not less
  than a majority in aggregate  principal amount of the Securities of all series
  affected then  outstanding;  provided that, if the payment within a reasonable
  time to the  Trustee  of the  costs,  expenses  or  liabilities  likely  to be
  incurred by it in the making of such  investigation  is, in the opinion of the
  Trustee,  not reasonably assured to the Trustee by the security afforded to it
  by the terms of this Indenture,  the Trustee may require reasonable  indemnity
  against such expenses or liabilities as a condition to proceeding.

     SECTION 7.3.  Individual Rights of Trustee.  The Trustee, in its individual
or any other  capacity,  may become the owner or pledgee of  Securities  and may
otherwise deal with the Company or its Affiliates  with the same rights it would
have if it were not the  Trustee.  Any Agent  may do the same with like  rights.
However,  the Trustee is subject to Trust Indenture Act Sections 310(b) and 311.
For purposes of Trust  Indenture  Act Section  311(b)(4)  and (6), the following
terms shall mean:

     (a) "cash  transaction"  means any  transaction  in which full  payment for
  goods or securities sold is made within seven days after delivery of the goods
  or  securities  in currency or in checks or other  orders  drawn upon banks or
  bankers and payable upon demand; and

     (b) "self-liquidating paper" means any draft, bill of exchange,  acceptance
  or obligation which is made, drawn,  negotiated or incurred by the Company for
  the purpose of financing the purchase,  processing,  manufacturing,  shipment,
  storage  or sale of  goods,  wares or  merchandise  and  which is  secured  by
  documents evidencing title to, possession of, or a lien upon, the goods, wares
  or  merchandise or the  receivables  or proceeds  arising from the 

                                      -45-


  sale of the goods, wares or merchandise previously  constituting the security,
  provided  the  security is received  by the  Trustee  simultaneously  with the
  creation  of the  creditor  relationship  with the  Company  arising  from the
  making,  drawing,  negotiating  or incurring  of the draft,  bill of exchange,
  acceptance or obligation.

     SECTION 7.4. Trustee's Disclaimer. The recitals contained herein and in the
Securities (except the Trustee's  certificate of authentication)  shall be taken
as statements  of the Company and not of the Trustee and the Trustee  assumes no
responsibility  for the correctness of the same.  Neither the Trustee nor any of
its agents (i) makes any  representation  as to the validity or adequacy of this
Indenture or the Securities and (ii) shall be accountable  for the Company's use
or application of the proceeds from the Securities.

     SECTION  7.5.  Notice  of  Default.  If any  Default  with  respect  to the
Securities of any series  occurs and is continuing  and if such Default is known
to the actual  knowledge  of a  Responsible  Officer  with the  Corporate  Trust
Department  of the Trustee,  the Trustee shall give to each Holder of Securities
of such series notice of such Default  within 90 days after it occurs (i) if any
Unregistered  Securities  of such  series are then  outstanding,  to the Holders
thereof, by publication at least once in an Authorized  Newspaper in the Borough
of Manhattan,  The City of New York and at least once in an Authorized Newspaper
in London and (ii) to all Holders of Securities of such series in the manner and
to the extent provided in Section 313(c) of the Trust Indenture Act, unless such
Default  shall have been cured or waived  before the mailing or  publication  of
such notice;  provided,  however,  that,  except in the case of a Default in the
payment of the  Principal of or interest on any  Security,  the Trustee shall be
protected  in  withholding  such notice if the Trustee in good faith  determines
that the withholding of such notice is in the interests of the Holders.

     SECTION 7.6.  Reports by Trustee to Holders.  Within 60 days after each May
15, beginning with May 15, 1999, the Trustee shall mail to each Holder as and to
the extent  provided in Trust  Indenture Act Section 313(c) a brief report dated
as of such May 15, if required by Trust Indenture Act Section 313(a).

     SECTION  7.7.  Compensation  and  Indemnity.  The Company  shall pay to the
Trustee such  compensation  as shall be agreed upon in writing from time to time
for its services.  The  compensation  of the Trustee shall not be limited by any
law on  compensation  of a  Trustee  of an  express  trust.  The  Company  shall
reimburse the Trustee upon request for all  reasonable  




                                      -46-


out-of-pocket  expenses,  disbursements  and  advances  incurred  or made by the
Trustee. Such expenses shall include the reasonable compensation and expenses of
the Trustee's agents, counsel and other persons not regularly in its employ.

     The Company shall indemnify the Trustee for, and hold it harmless  against,
any loss or liability or expense incurred by it without  negligence or bad faith
on  its  part  arising  out  of  or  in  connection   with  the   acceptance  or
administration  of this  Indenture  and the  Securities  or the  issuance of the
Securities or of series thereof or the trusts  hereunder and the  performance of
duties under this Indenture and the Securities, including the costs and expenses
of defending  itself  against or  investigating  any claim or  liability  and of
complying  with any process  served upon it or any of its officers in connection
with the  exercise  or  performance  of any of its  powers or duties  under this
Indenture and the Securities.

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

     The  obligations  of the  Company  under  this  Section to  compensate  and
indemnify the Trustee and each  predecessor  Trustee and to pay or reimburse the
Trustee and each predecessor  Trustee for expenses,  disbursements  and advances
shall  constitute  additional  indebtedness  hereunder  and  shall  survive  the
satisfaction  and discharge of this Indenture or the rejection or termination of
this Indenture under  bankruptcy law. Such  additional  indebtedness  shall be a
senior  claim to that of the  Securities  upon all  property  and funds  held or
collected by the Trustee as such,  except funds held in trust for the benefit of
the Holders of particular  Securities or coupons,  and the Securities are hereby
subordinated to such senior claim.  If the Trustee  renders  services and incurs
expenses  following an Event of Default under Section  6.1(d) or Section  6.1(e)
hereof, the parties hereto and the holders by their acceptance of the Securities
hereby  agree  that  such  expenses  are  intended  to  constitute  expenses  of
administration under any bankruptcy law.

     SECTION  7.8.  Replacement  of  Trustee.  A  resignation  or removal of the
Trustee as Trustee with respect to the Securities of any series and  appointment
of a successor  Trustee as Trustee with respect to the  Securities of any series
shall  become  effective  only  upon  the  successor  Trustee's   acceptance  of
appointment as provided in this Section 7.8.

                                      -47-


     The Trustee may resign as Trustee  with  respect to the  Securities  of any
series at any time by so  notifying  the  Company in  writing.  The Holders of a
majority in principal  amount of the  outstanding  Securities  of any series may
remove the Trustee as Trustee with respect to the  Securities  of such series by
so  notifying  the Trustee in writing and may appoint a successor  Trustee  with
respect  thereto  with the  consent of the  Company.  The Company may remove the
Trustee as Trustee  with  respect  to the  Securities  of any series if: (i) the
Trustee is no longer  eligible  under Section 7.10 of this  Indenture;  (ii) the
Trustee is adjudged a bankrupt or  insolvent;  (iii) a receiver or other  public
officer takes charge of the Trustee or its property; or (iv) the Trustee becomes
incapable of acting.

     If the  Trustee  resigns  or is  removed  as  Trustee  with  respect to the
Securities of any series,  or if a vacancy  exists in the office of Trustee with
respect to the  Securities  of any  series for any  reason,  the  Company  shall
promptly appoint a successor Trustee with respect thereto. Within one year after
the  successor  Trustee  takes  office,  the Holders of a majority in  principal
amount of the  outstanding  Securities  of such  series may  appoint a successor
Trustee in respect of such Securities to replace the successor Trustee appointed
by the Company.  If the successor  Trustee with respect to the Securities of any
series does not deliver its written  acceptance  required by the next succeeding
paragraph of this Section 7.8 within 30 days after the retiring  Trustee resigns
or is removed, the retiring Trustee, the Company or the Holders of a majority in
principal  amount of the outstanding  Securities of such series may petition any
court of competent  jurisdiction for the appointment of a successor Trustee with
respect thereto.

     A successor  Trustee  with  respect to the  Securities  of any series shall
deliver a written  acceptance of its appointment to the retiring  Trustee and to
the Company. Immediately after the delivery of such written acceptance,  subject
to the lien provided for in Section 7.7, (i) the retiring Trustee shall transfer
all property  held by it as Trustee in respect of the  Securities of such series
to the  successor  Trustee,  (ii) the  resignation  or removal  of the  retiring
Trustee in respect of the  Securities of such series shall become  effective and
(iii) the successor Trustee shall have all the rights,  powers and duties of the
Trustee in respect of the  Securities  of such series  under this  Indenture.  A
successor  Trustee  shall  mail  notice  of its  succession  to each  Holder  of
Securities of such series.

     Upon request of any such successor  Trustee,  the Company shall execute any
and all  instruments  for more fully and certainly  vesting in and confirming to
such  successor  Trustee 



                                      -48-


all such rights, powers and trusts referred to in the preceding paragraph.

     The  Company  shall give notice of any  resignation  and any removal of the
Trustee with respect to the  Securities of any series and each  appointment of a
successor  Trustee in respect of the Securities of such series to all Holders of
Securities  of such series.  Each notice shall include the name of the successor
Trustee and the address of its Corporate Trust Office.

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

     SECTION 7.9. Successor Trustee by Merger, Etc. If the Trustee  consolidates
with,  merges or converts  into,  or transfers all or  substantially  all of its
corporate   trust   business  to,  another   corporation  or  national   banking
association,  the  resulting,  surviving or transferee  corporation  or national
banking  association without any further act shall be the successor Trustee with
the same  effect  as if the  successor  Trustee  had been  named as the  Trustee
herein.

     SECTION 7.10.  Eligibility.  This Indenture shall always have a Trustee who
satisfies the  requirements of Trust  Indenture Act Section 310(a).  The Trustee
shall have a combined  capital and surplus of at least  $25,000,000 as set forth
in its most recent published annual report of condition.

     SECTION  7.11.  Money Held in Trust.  The  Trustee  shall not be liable for
interest on any money  received by it except as the Trustee may agree in writing
with the Company. Money held in trust by the Trustee need not be segregated from
other  funds  except to the extent  required by law and except for money held in
trust under Article 8 of this Indenture.

                                    ARTICLE 8

                    SATISFACTION AND DISCHARGE OF INDENTURE;
                                UNCLAIMED MONEYS

     SECTION 8.1.  Satisfaction  and Discharge of Indenture.  If at any time (a)
the Company  shall have paid or caused to be paid the  principal of and interest
on all the Securities of any series outstanding hereunder (other than Securities
of such  series  which have been  destroyed,  lost or stolen and which 



                                      -49-


have been  replaced  or paid as  provided  in Section  2.8) as and when the same
shall have become due and payable,  or (b) the Company  shall have  delivered to
the  Trustee  for  cancellation   all  securities  of  any  series   theretofore
authenticated  (other than any  Securities  of such series which shall have been
destroyed, lost or stolen and which shall have been replaced or paid as provided
in Section  2.8) or (c) (i) all the  securities  of such series not  theretofore
delivered to the Trustee for cancellation shall have become due and payable,  or
are by their terms to become due and payable within one year or are to be called
for redemption  within one year under  arrangements  satisfactory to the Trustee
for the  giving  of  notice  of  redemption,  and (ii) the  Company  shall  have
irrevocably  deposited or caused to be deposited with the Trustee as trust funds
the entire amount in cash (other than moneys repaid by the Trustee or any paying
agent  to the  Company  in  accordance  with  Section  8.4) or  U.S.  Government
Obligations,  maturing as to principal  and interest in such amounts and at such
times as will insure the  availability  of cash sufficient to pay at maturity or
upon redemption all Securities of such series (other than any Securities of such
series which shall have been destroyed, lost or stolen and which shall have been
replaced or paid as provided in Section  2.8) not  theretofore  delivered to the
Trustee for cancellation,  including principal and interest due or to become due
on or prior to such  date of  maturity  as the case may be,  and if, in any such
case,  the  Company  shall also pay or cause to be paid all other  sums  payable
hereunder by the Company with respect to  Securities  of such series,  then this
Indenture shall cease to be of further effect with respect to Securities of such
series  (except as to (i) rights of  registration  of transfer  and  exchange os
securities of such series,  and the Company's right of optional  redemption,  if
any,  (ii)  substitution  of  mutilated,  defaced,  destroyed,  lost  or  stolen

Trustee  hereunder and (v) the rights of the  Securityholders  of such series as
beneficiaries  hereof with respect to the property so deposited with the Trustee
payable  to all or any of them),  and the  Trustee,  on  demand  of the  Company
accompanied  by an  Officers'  Certificate  and an Opinion of Counsel and at the
cost and expense of the Company, shall execute proper instruments  acknowledging
such satisfaction of and discharging this Indenture with respect to such series;
provided,  that the rights of Holders of the  Securities  to receive  amounts in
respect of principal of and interest on the Securities held by them shall not be
delayed longer than required by  then-applicable  mandatory rules or policies of
any securities exchange upon which the Securi-



                                      -50-


ties are listed.  The Company  agrees to reimburse  the Trustee for any costs or
expenses  thereafter  reasonably  and properly  incurred and to  compensate  the
Trustee for any services  thereafter  reasonably  and  properly  rendered by the
Trustee in connection with this Indenture or the Securities of such series.

     SECTION  8.2.  Application  by Trustee of Funds  Deposited  for  Payment of
Securities.  Subject  to  Section  8.4 and to the  subordination  provisions  of
Article 11 hereof, all moneys deposited with the Trustee pursuant to Section 8.1
shall be held in trust and  applied by it to the  payment,  either  directly  or
through any paying agent (including the Company acting as its own paying agent),
to the Holders of the  particular  Securities  of such series for the payment or
redemption  of which such moneys have been  deposited  with the Trustee,  of all
sums due and to become due thereon for principal  and  interest;  but such money
need not be segregated from other funds except to the extent required by law.

     SECTION 8.3.  Repayment of Moneys Held by Paying Agent.  In connection with
the  satisfaction  and discharge of this Indenture with respect to Securities of
any series,  all moneys then held by any paying  agent under the  provisions  of
this Indenture with respect to such series of Securities  shall,  upon demand of
the Company,  be repaid to it or paid to the Trustee and  thereupon  such paying
agent shall be released from all further liability with respect to such moneys.

     SECTION 8.4.  Return of Moneys Held by Trustee and Paying  Agent  Unclaimed
for Two Years.  Any moneys  deposited  with or paid to the Trustee or any paying
agent for the payment of the  principal  of or  interest on any  Security of any
series and not applied but remaining unclaimed for two years after the date upon
which such principal or interest shall have become due and payable,  shall, upon
the written  request of the Company and unless  otherwise  required by mandatory
provisions  of  applicable  escheat or abandoned or unclaimed  property  law, be
repaid to the Company by the Trustee for such series or such paying  agent,  and
the Holder of the Security of such series shall,  unless  otherwise  required by
mandatory  provisions of applicable  escheat or abandoned or unclaimed  property
laws,  thereafter look only to the Company for any payment which such Holder may
be entitled to collect,  and all  liability  of the Trustee or any paying  agent
with respect to such moneys shall thereupon cease.

     SECTION 8.5.  Defeasance  and Discharge of Indenture.  The Company shall be
deemed to have  paid and shall be  discharged  from any and all  obligations  in
respect of the  Securities  of any  series,  on the 123rd day after the  deposit
referred  to in clause  (A) hereof has been  made,  and the  provisions  of 



                                      -51-


this  Indenture  shall no longer be in effect with respect to the  Securities of
such  series (and the  Trustee,  at the expense of the  Company,  shall  execute
proper  instruments  acknowledging  the  same),  except  as to:  (a)  rights  of
registration  of transfer  and  exchange,  and the  Company's  right of optional
redemption, (b) substitution of apparently mutilated,  defaced,  destroyed, lost
or stolen  Securities,  (c) rights of holders to receive  payments of  principal
thereof and interest  thereon,  upon the original stated due dates therefor (but
not upon  acceleration),  (d) the  rights,  obligations  and  immunities  of the
Trustee  hereunder and (e) the rights of the  Securityholders  of such series as
beneficiaries  hereof with respect to the property so deposited with the Trustee
payable to all or any of them; provided that the following conditions shall have
been satisfied:

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

     (B) the Company has  delivered  to the Trustee (i) either (x) an Opinion of
  Counsel to the effect  that  Holders of  Securities  of such  series  will not
  recognize income,  gain or loss for federal income tax purposes as a result of
  the  Company's  exercise  of its  option  under this  Section  8.5 and will be
  subject to federal income tax on the same amount and in the same manner and at
  the same times as 




                                      -52-


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

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

     (D) the Company is not  prohibited  from making  payments in respect of the
  Securities by Article 11 hereof; and

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

     SECTION 8.6.  Defeasance  of Certain  Obligations.  The Company may omit to
comply with any term,  provision or condition  set forth in, and this  Indenture
will no longer be in effect  with  respect  to,  any  covenant  in  Article 4 or
Section 5.1  established  pursuant to Section 2.3 in any indenture  supplemental
hereto and clause (c) (with respect to any covenants in Article 4 or Section 5.1
established  pursuant to Section 2.3 in any indenture  supplemental  hereto) and
clause (f) of Section 6.1 shall be deemed not to be an Event of Default, and the
provisions  of Article 11 shall not apply with respect to the  Securities of any
series, if

                                      -53-


     (A) with reference to this Section 8.6, the Company has deposited or caused
  to be irrevocably  deposited with the Trustee (or another  trustee  satisfying
  the requirements of Section 7.8) as trust funds in trust, specifically pledged
  as security  for, and  dedicated  solely to, the benefit of the Holders of the
  Securities of such series and the Indenture  with respect to the Securities of
  such series, (i) money in an amount or (ii) U.S. Government  Obligations which
  through the payment of interest and principal in respect thereof in accordance
  with  their  terms  will  provide  not later than one day before the due dates
  thereof or  earlier  redemption  (irrevocably  provided  for under  agreements
  satisfactory to the Trustee),  as the case may be, of any payment  referred to
  in  subclause  (x) or (y) of this  clause (A) money in an  amount,  or (iii) a
  combination  thereof,  sufficient,  in the opinion of a nationally  recognized
  firm of independent  public accountants  expressed in a written  certification
  thereof delivered to the Trustee,  to pay and discharge without  consideration
  of the  reinvestment of such interest and after payment of all federal,  state
  and local taxes or other charges and assessments in respect thereof payable by
  the Trustee (x) the principal of,  premium,  if any, and each  installment  of
  interest  on the  outstanding  Securities  on the due date  thereof or earlier
  redemption  (irrevocably  provided for under arrangements  satisfactory to the
  Trustee),  as the case may be, and (y) any mandatory  sinking fund payments or
  analogous  payments  applicable  to the  Securities  of  such  series  and the
  Indenture  with respect to the  Securities  of such series on the day on which
  such  payments  are due and  payable  in  accordance  with  the  terms  of the
  Indenture and of  Securities of such series and the Indenture  with respect to
  the Securities of such series;

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

                                      -54-


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

     (D) the Company is not  prohibited  from making  payments in respect of the
  Securities by Article 11 hereof; and

  securities  exchange,  the Company has  delivered to the Trustee an Opinion of
  Counsel to the effect that the  Securities of such series will not be delisted
  as a result of such deposit, defeasance and discharge.

     SECTION  8.7.  Reinstatement.  If the Trustee or paying  agent is unable to
apply any monies or U.S. Government  Obligations in accordance with Article 8 by
reason of any legal  proceeding  or by  reason of any order or  judgment  of any
court or governmental authority enjoining,  restraining or otherwise prohibiting
such  application,  the  Company's  obligations  under  this  Indenture  and the
Securities  shall be revived and  reinstated  as though no deposit had  occurred
pursuant  to this  Article  until such time as the  Trustee  or paying  agent is
permitted to apply all such monies or U.S. Government  Obligations in accordance
with Article 8; provided,  however,  that if the Company has made any payment of
principal of or interest on any Securities  because of the  reinstatement of its
obligations,  the Company  shall be  subrogated  to the rights of the Holders of
such  Securities  to receive  such  payment  from the monies or U.S.  Government
Obligations held by the Trustee or paying agent.

                                    ARTICLE 9

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

     SECTION 9.1.  Without  Consent of Holders.  The Company and the Trustee may
amend or  supplement  this  Indenture or the  Securities  of any series  without
notice to or the consent of any Holder:

                                      -55-


     (1) to cure any  ambiguity,  defect  or  inconsistency  in this  Indenture;
  provided  that  such  amendments  or  supplements  shall  not  materially  and
  adversely affect the interests of the Holders;

     (2) to comply with Article 5;

     (3) to comply with any  requirements  of the Commission in connection  with
  the qualification of this Indenture under the Trust Indenture Act;

     (4) to evidence and provide for the  acceptance  of  appointment  hereunder
  with respect to the Securities of any or all series by a successor Trustee;

     (5) to establish  the form or forms or terms of Securities of any series or
  of the coupons appertaining to such Securities as permitted by Section 2.3;

     (6) to provide for  uncertificated  or Unregistered  Securities and to make
  all appropriate changes for such purpose; and

     (7) to make any change that does not  materially  and adversely  affect the
  rights of any Holder.

     SECTION  9.2.  With  Consent of Holders.  Subject to Sections  6.4 and 6.7,
without prior notice to any Holders,  the Company and the Trustee may amend this
Indenture  and the  Securities  of any series  with the  written  consent of the
Holders of a majority in principal  amount of the outstanding  Securities of all
series affected by such amendment (all such series voting as a separate  class),
and the Holders of a majority in principal amount of the outstanding  Securities
of all series  affected  thereby (all such series voting as a separate class) by
written  notice to the Trustee may waive future  compliance  by the Company with
any provision of this Indenture or the Securities of such series.

     Notwithstanding  the provisions of this Section 9.2, without the consent of
each  Holder  affected  thereby,  an  amendment  or waiver,  including  a waiver
pursuant to Section 6.4, may not:

     (i) change the stated  maturity of the  Principal  of, or any sinking  fund
  obligation or any installment of interest on, such Holder's Security,

                                      -56-


     (ii) reduce the Principal  amount  thereof or the rate of interest  thereon
  (including any amount in respect of original issue discount);

     (iii) reduce the above stated  percentage  of  outstanding  Securities  the
  consent of whose  holders is necessary to modify or amend the  Indenture  with
  respect to the Securities of the relevant series; and

     (iv) reduce the percentage in principal amount of outstanding Securities of
  the  relevant  series  the  consent  of  whose  Holders  is  required  for any
  supplemental  indenture,  for any waiver of compliance with certain provisions
  of this Indenture or certain Defaults and their  consequences  provided for in
  this Indenture.

     A supplemental  indenture which changes or eliminates any covenant or other
provision of this  Indenture  which has expressly  been included  solely for the
benefit of one or more  particular  series of Securities,  or which modifies the
rights of Holders of  Securities of such series with respect to such covenant or
provision,  shall be deemed not to affect the rights under this Indenture of the
Holders of Securities of any other series or of the coupons appertaining to such
Securities.

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

     After an  amendment,  supplement  or waiver  under this Section 9.2 becomes
effective,  the  Company  shall give to the  Holders  affected  thereby a notice
briefly  describing the amendment,  supplement or waiver.  The Company will mail
supplemental  indentures to Holders upon request.  Any failure of the Company to
mail such notice, or any defect therein,  shall not, however,  in any way impair
or affect the validity of any such supplemental indenture or waiver.

     SECTION 9.3. Revocation and Effect of Consent. Until an amendment or waiver
becomes  effective,  a consent to it by a Holder is a continuing  consent by the
Holder and every  subsequent  Holder of a Security or portion of a Security that
evidences  the same  debt as the  Security  of the  consenting  Holder,  even if
notation of the consent is not made on any Security. However, any such Holder or
subsequent  Holder may revoke the  consent as to its  Security or portion of its
Security.  Such revocation  shall be effective only if the Trustee  receives the
notice of revocation before the date the amendment, supplement or waiver becomes
effective.  An  amendment,  supplement  or 




                                      -57-


waiver shall become effective with respect to any Securities affected thereby on
receipt  by the  Trustee  of  written  consents  from the  requisite  Holders of
outstanding Securities affected thereby.

     The Company may,  but shall not be  obligated  to, fix a record date (which
may be not less  than five nor more than 60 days  prior to the  solicitation  of
consents) for the purpose of  determining  the Holders of the  Securities of any
series affected entitled to consent to any amendment, supplement or waiver. If a
record date is fixed, then, notwithstanding the immediately preceding paragraph,
those  Persons  who  were  such  Holders  at such  record  date (or  their  duly
designated  proxies) and only those Persons shall be entitled to consent to such
amendment,  supplement  or waiver or to revoke  any  consent  previously  given,
whether or not such Persons  continue to be such Holders after such record date.
No such  consent  shall be valid or  effective  for more than 90 days after such
record date.

     After an amendment,  supplement or waiver becomes effective with respect to
the  Securities of any series  affected  thereby,  it shall bind every Holder of
such Securities unless it is of the type described in any of clauses (i) through
(iv) of Section 9.2. In case of an amendment or waiver of the type  described in
clauses (i) through (iv) of Section 9.2, the amendment or waiver shall bind each
such Holder who has  consented to it and every  subsequent  Holder of a Security
that evidences the same indebtedness as the Security of the consenting Holder.

     SECTION  9.4.  Notation  on or  Exchange of  Securities.  If an  amendment,
supplement or waiver changes the terms of any Security,  the Trustee may require
the  Holder  thereof  to deliver it to the  Trustee.  The  Trustee  may place an
appropriate  notation on the Security  about the changed  terms and return it to
the Holder and the Trustee may place an appropriate  notation on any Security of
such  series  thereafter  authenticated.  Alternatively,  if the  Company or the
Trustee so determines,  the Company in exchange for the Security shall issue and
the Trustee shall  authenticate a new Security of the same series and tenor that
reflects the changed terms.

     SECTION 9.5. Trustee to Sign Amendments, Etc. The Trustee shall be entitled
to receive,  and shall be fully protected in relying upon, an Opinion of Counsel
stating that the execution of any  amendment,  supplement  or waiver  authorized
pursuant to this Article 9 is authorized or permitted by this Indenture, stating
that all requisite  consents have been obtained or that no consents are required
and stating that such supplemental  indenture  constitutes the legal,  valid and
binding 




                                      -58-


obligation of the Company,  enforceable  against the Company in accordance  with
its terms, subject to customary  exceptions.  Subject to the preceding sentence,
the Trustee shall sign such amendment, supplement or waiver if the same does not
adversely  affect the rights of the  Trustee.  The Trustee may, but shall not be
obligated to, execute any such amendment,  supplement or waiver that affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

     SECTION  9.6.  Conformity  with Trust  Indenture  Act.  Every  supplemental
indenture  executed pursuant to this Article 9 shall conform to the requirements
of the Trust Indenture Act as then in effect.

                                   ARTICLE 10

                                  MISCELLANEOUS

     SECTION 10.1. Trust Indenture Act of 1939. This Indenture shall incorporate
and be governed by the  provisions of the Trust  Indenture Act that are required
to be part of and to govern indentures qualified under the Trust Indenture Act.

     SECTION 10.2.  Notices.  Any notice or communication  shall be sufficiently
given if written and (a) if delivered  in person when  received or (b) if mailed
by first class mail 5 days after mailing,  or (c) as between the Company and the
Trustee if sent by facsimile  transmission,  when transmission is confirmed,  in
each case addressed as follows:

     if to the Company:

            The AES Corporation
            1001 North 19th Street
            Arlington, VA  22209
            Telecopy:  (703) 528-4510
            Attention:  General Counsel

     if to the Trustee:

             The First National Bank of Chicago
             One First National Bank Plaza
             Chicago, IL  60670-0126
             Telecopy:  (312) 407-1708
             Attention:  Corporate Trust Services Division

                                      -59-


     The  Company or the  Trustee by written  notice to the other may  designate
additional or different addresses for subsequent notices or communications.

     Any notice or communication  shall be sufficiently  given to Holders of any
Unregistered Securities, by publication at least once in an Authorized Newspaper
in The City of New York,  or with  respect to any Security the interest on which
is based on the offered quotations in the interbank Eurodollar market for dollar
deposits at least once in an Authorized  Newspaper in London,  and by mailing to
the Holders  thereof who have filed their names and  addresses  with the Trustee
pursuant to Section  313(c)(2) of the Trust  Indenture Act at such  addresses as
were so  furnished  to the Trustee and to Holders of  Registered  Securities  by
mailing to such Holders at their  addresses as they shall appear on the Security
Register. Notice mailed shall be sufficiently given if so mailed within the time
prescribed. Copies of any such communication or notice to a Holder shall also be
mailed to the Trustee and each Agent at the same time.

     Failure to mail a notice or  communication  to a Holder or any defect in it
shall not affect  its  sufficiency  with  respect  to other  Holders.  Except as
otherwise provided in this Indenture,  if a notice or communication is mailed in
the manner  provided in this Section 10.2, it is duly given,  whether or not the
addressee receives it.

     Where this Indenture provides for notice in any manner,  such notice may be
waived in writing by the Person  entitled to receive such notice,  either before
or after the event,  and such waiver  shall be the  equivalent  of such  notice.
Waivers of notice by Holders  shall be filed with the  Trustee,  but such filing
shall not be a  condition  precedent  to the  validity  of any  action  taken in
reliance upon such waiver.

     In case it shall be  impracticable  to give notice as herein  contemplated,
then such  notification  as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

     SECTION 10.3. Certificate and Opinion as to Conditions Precedent.  Upon any
request or  application  by the Company to the Trustee to take any action  under
this Indenture, the Company shall furnish to the Trustee:

     (i) an Officers'  Certificate  stating that, in the opinion of the signers,
  all conditions  precedent,  if any, provided for in this Indenture relating to
  the proposed action have been complied with; and

                                      -60-


     (ii) an Opinion of Counsel  stating  that,  in the opinion of such counsel,
  all such conditions precedent have been complied with.

     SECTION  10.4.   Statements  Required  in  Certificate  or  Opinion.   Each
certificate  or opinion with respect to compliance  with a condition or covenant
provided for in this Indenture shall include:

     (i) a statement  that each person  signing such  certificate or opinion has
  read such covenant or condition and the definitions herein relating thereto;

     (ii) a brief  statement  as to the nature and scope of the  examination  or
  investigation   upon  which  the  statement  or  opinion   contained  in  such
  certificate or opinion is based;

     (iii) a statement  that,  in the opinion of each such  person,  he has made
  such  examination or investigation as is necessary to enable him to express an
  informed  opinion as to whether or not such  covenant  or  condition  has been
  complied with; and

     (iv) a statement  as to whether or not, in the opinion of each such person,
  such condition or covenant has been complied with;  provided,  however,  that,
  with  respect  to  matters  of fact,  an  Opinion  of  Counsel  may rely on an
  Officers' Certificate or certificates of public officials.

     SECTION 10.5. Evidence of Ownership. The Company, the Trustee and any agent
of the Company or the Trustee may deem and treat the Holder of any  Unregistered
Security and the Holder of any coupon as the absolute owner of such Unregistered
Security or coupon (whether or not such Unregistered Security or coupon shall be
overdue) for the purpose of receiving  payment thereof or on account thereof and
for all other purposes,  and neither the Company,  the Trustee, nor any agent of
the Company or the Trustee shall be affected by any notice to the contrary.  The
fact  of  the  holding  by any  Holder  of an  Unregistered  Security,  and  the
identifying number of such Security and the date of his holding the same, may be
proved by the  production of such  Security or by a certificate  executed by any
trust company,  bank,  banker or recognized  securities dealer wherever situated
satisfactory to the Trustee,  if such certificate shall be deemed by the Trustee
to be satisfactory. Each such certificate shall be dated and shall state that on
the date thereof a Security bearing a specified identifying number was deposited
with or exhibited to such trust company,  bank, banker or recognized  securities
dealer by the person  named in such  



                                      -61-


certificate.  Any such  certificate  may be  issued  in  respect  of one or more
Unregistered  Securities  specified therein.  The holding by the person named in
any such certificate of any Unregistered  Securities  specified therein shall be
presumed to continue for a period of one year from the date of such  certificate
unless at the time of any determination of such holding (1) another  certificate
bearing a later date issued in respect of the same Securities  shall be produced
or (2) the  Security  specified  in such  certificate  shall be produced by some
other  Person,  or (3) the  Security  specified in such  certificate  shall have
ceased  to be  outstanding.  Subject  to  Article  7,  the  fact and date of the
execution of any such  instrument and the amount and numbers of Securities  held
by the Person so executing such instrument may also be proven in accordance with
such reasonable  rules and regulations as may be prescribed by the Trustee or in
any other manner which the Trustee may deem sufficient.

     The  Company,  the  Trustee and any agent of the Company or the Trustee may
deem and  treat  the  person  in whose  name any  Registered  Security  shall be
registered  upon the Security  Register for such series as the absolute owner of
such  Registered  Security  (whether or not such  Registered  Security  shall be
overdue and  notwithstanding any notation of ownership or other writing thereon)
for the purpose of receiving  payment of or on account of the  Principal of and,
subject  to the  provisions  of this  Indenture,  interest  on  such  Registered
Security and for all other purposes; and neither the Company nor the Trustee nor
any agent of the Company or the  Trustee  shall be affected by any notice to the
contrary.

     SECTION 10.6. Rules by Trustee, Paying Agent or Registrar.  The Trustee may
make reasonable rules for action by or at a meeting of Holders. The Paying Agent
or Registrar may make reasonable rules for its functions.

     SECTION  10.7.  Payment  Date Other Than a  Business  Day.  If any date for
payment of Principal or interest on any Security  shall not be a Business Day at
any place of payment, then payment of Principal of or interest on such Security,
as the case may be,  need not be made on such date,  but may be made on the next
succeeding  Business  Day at any place of payment with the same force and effect
as if made on such date and no interest  shall accrue in respect of such payment
for the period from and after such date.

     SECTION 10.8. Governing Law. The laws of the State of New York shall govern
this Indenture and the Securities.



                                      -62-


     SECTION 10.9. No Adverse Interpretation of Other Agreements. This Indenture
may not be used to interpret  another indenture or loan or debt agreement of the
Company or any  Subsidiary of the Company.  Any such  indenture or agreement may
not be used to interpret this Indenture.

     SECTION 10.10. Successors.  All agreements of the Company in this Indenture
and the Securities  shall bind its successors.  All agreements of the Trustee in
this Indenture shall bind its successors.

     SECTION  10.11.  Duplicate  Originals.  The  parties may sign any number of
copies of this Indenture. Each signed copy shall be an original, but all of them
together represent the same agreement.

     SECTION 10.12. Separability.  In case any provision in this Indenture or in
the  Securities  shall be  invalid,  illegal  or  unenforceable,  the  validity,
legality and enforceability of the remaining  provisions shall not in any way be
affected or impaired thereby.

     SECTION 10.13. Table of Contents,  Headings, Etc. The Table of Contents and
headings of the Articles and Sections of this  Indenture  have been inserted for
convenience of reference  only, are not to be considered a part hereof and shall
in no way modify or restrict any of the terms and provisions hereof.

     SECTION  10.14.  Incorporators,  Stockholders,  Officers  and  Directors of
Company  Exempt  from  Individual  Liability.  No  recourse  under  or upon  any
obligation,  covenant or agreement  contained in this Indenture or any indenture
supplemental hereto, or in any Security or any coupons appertaining  thereto, or
because  of  any  indebtedness  evidenced  thereby,  shall  be had  against  any
incorporator,  as such or  against  any past,  present  or  future  stockholder,
officer,  director or  employee,  as such,  of the Company or of any  successor,
either directly or through the Company or any successor,  under any rule of law,
statute or  constitutional  provision or by the enforcement of any assessment or
by any legal or equitable  proceeding or  otherwise,  all such  liability  being
expressly  waived and  released  by the  acceptance  of the  Securities  and the
coupons  appertaining  thereto  by  the  holders  thereof  and  as  part  of the
consideration  for the  issue of the  Securities  and the  coupons  appertaining
thereto.

     SECTION 10.15. Judgment Currency. The Company agrees, to the fullest extent
that it may effectively do so under  applicable law, that (a) if for the purpose
of  obtaining  judgment in any court it is  necessary  to convert the sum due in
respect of the  Principal  of or interest on the  Securities  of 



                                      -63-


any series (the "Required Currency") into a currency in which a judgment will be
rendered (the "Judgment Currency"),  the rate of exchange used shall be the rate
at which in accordance with normal banking procedures the Trustee could purchase
in The City of New York the Required  Currency with the Judgment Currency on the
day on which final  unappealable  judgment is entered,  unless such day is not a
Business  Day,  then,  to the extent  permitted by  applicable  law, the rate of
exchange  used  shall be the rate at which in  accordance  with  normal  banking
procedures  the  Trustee  could  purchase  in The City of New York the  Required
Currency  with the Judgment  Currency on the Business Day  preceding  the day on
which final unappealable  judgment is entered and (b) its obligations under this
Indenture to make payments in the Required  Currency (i) shall not be discharged
or satisfied by any tender, or any recovery pursuant to any judgment (whether or
not entered in accordance with  subsection  (a)), in any currency other than the
Required  Currency,  except to the extent  that such  tender or  recovery  shall
result in the actual  receipt,  by the payee, of the full amount of the Required
Currency  expressed  to be payable in  respect of such  payments,  (ii) shall be
enforceable as an  alternative or additional  cause of action for the purpose of
recovering  in the Required  Currency  the amount,  if any, by which such actual
receipt  shall  fall  short of the  full  amount  of the  Required  Currency  so
expressed  to be payable  and (iii)  shall not be  affected  by  judgment  being
obtained for any other sum due under this Indenture.

                                   ARTICLE 11

                           SUBORDINATION OF SECURITIES

     SECTION 11.1.  Agreement to Subordinate.  The Company covenants and agrees,
and each  Holder  of  Securities  issued  hereunder  by his  acceptance  thereof
likewise  covenants and agrees,  that all Securities  shall be issued subject to
the provisions of this Article;  and each person  holding any Security,  whether
upon original issue or upon transfer, assignment or exchange thereof accepts and
agrees that the  Principal of and interest on all  Securities  issued  hereunder
shall,  to the extent and in the manner herein set forth,  be  subordinated  and
subject in right to the prior  payment  in full of all  Senior and  Subordinated
Debt.

     SECTION  11.2.  Payments  to  Securityholders.  No  payments  on account of
Principal of, Change of Control  purchase  price,  or interest on the Securities
shall be made if at the time of such payment or immediately  after giving effect
thereto  


                                      -64-


there  shall  exist a default  in any  payment  with  respect  to any Senior and
Subordinated Debt, and such event of default shall not have been cured or waived
or shall not have ceased to exist.  In addition,  during the  continuance of any
other event of default (other than a payment default) with respect to Designated
Senior and  Subordinated  Debt  pursuant  to which the  maturity  thereof may be
accelerated, from and after the date of receipt by the Trustee of written notice
from the  holders of such  Designated  Senior and  Subordinated  Debt or from an
agent of such holders,  no payments on account of  Principal,  Change of Control
purchase  price,  or  interest in respect of the  Securities  may be made by the
Company  for a period  ("Payment  Blockage  Period")  commencing  on the date of
delivery  of such notice and ending 179 days  thereafter  (unless  such  Payment
Blockage  Period shall be terminated  by written  notice to the Trustee from the
holders of such Designated Senior and Subordinated Debt or from an agent of such
holders,  or such  event of  default  has been  cured or waived or has ceased to
exist).  Only one Payment  Blockage  Period may be commenced with respect to the
Securities  during any period of 360 consecutive days. No event of default which
existed  or was  continuing  on the  date  of the  commencement  of any  Payment
Blockage  Period with respect to the  Designated  Senior and  Subordinated  Debt
initiating  such Payment  Blockage  Period shall be or be made the basis for the
commencement  of any subsequent  Payment  Blockage Period by the holders of such
Designated Senior and Subordinated Debt, unless such event of default shall have
been cured or waived for a period of not less than 90 consecutive days.

     Upon any  payment or  distribution  of assets of the Company of any kind or
character,  whether in cash,  property  or  securities,  to  creditors  upon any
liquidation, dissolution, winding up, receivership,  reorganization,  assignment
for the  benefit of  creditors,  marshalling  of assets and  liabilities  or any
bankruptcy, insolvency or similar proceedings of the Company, all amounts due or
to become due upon all Senior and Subordinated Debt shall first be paid in full,
in cash or cash equivalents,  or payment thereof provided for in accordance with
its terms,  before any payment is made on account of the Principal of, Change of
Control  purchase  price,  or  interest  on the  indebtedness  evidenced  by the
Securities,   and  upon  any  such   liquidation,   dissolution,   winding   up,
receivership, reorganization, assignment, marshalling or proceeding, any payment
or  distribution  of assets of the Company of any kind or character,  whether in
cash,  property or  securities,  to which the Holders of the  Securities  or the
Trustee  under this  Indenture  would be  entitled,  except  for the  provisions
hereof, shall be paid by the Company or by any receiver,  trustee in bankruptcy,
liquidating trustee,  agent or other Person making such payment or distribution,
or by the Holders of the  Securities or by the 




                                      -65-


Trustee under this Indenture if received by them or it,  directly to the holders
of Senior and  Subordinated  Debt (pro rata to such  holders on the basis of the
respective  amounts of Senior and  Subordinated  Debt held by such  holders)  or
their  respective  representatives,  or to the  trustee  or  trustees  under any
indenture  pursuant to which any  instruments  evidencing any of such Senior and
Subordinated  Debt may have  been  issued,  as their  respective  interests  may
appear,  to the extent necessary to pay all Senior and Subordinated Debt in full
(including,  without  limitation,  except to the extent,  if any,  prohibited by
mandatory provisions of law,  post-petition  interest, in any such proceedings),
after giving  effect to any  concurrent  payment or  distribution  to or for the
holders of Senior and Subordinated  Debt,  before any payment or distribution is
made to the holders of the  indebtedness  evidenced by the  Securities or to the
Trustee under this Indenture.

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

     For purposes of this Article,  the words,  "cash,  property or  securities"
shall not be deemed to include  shares of stock of the Company as reorganized or
readjusted,  or securities of the Company or any other corporation  provided for
by a plan of arrangement,  reorganization or readjustment,  the payment of which
is subordinated (at least to the extent provided in this Article with respect to
the Securities) to the payment of all Senior and Subordinated  Debt which may at
the time be outstanding;  provided, that (i) the Senior and Subordinated Debt is
assumed by the new  corporation,  if any,  resulting from any such  arrangement,
reorganization or readjustment, and (ii) the rights of the holders of the Senior
and Subordinated  Debt are not, without the consent of such holders,  altered by
such  


                                      -66-


arrangement,  reorganization  or readjustment.  The consolidation of the Company
with, or the merger of the Company into, another  corporation or the liquidation
or  dissolution  of the  Company  following  the  conveyance  or transfer of its
property as an entirety, or substantially as an entirety, to another corporation
upon the  terms  and  conditions  provided  in  Article  5 shall not be deemed a
dissolution,  winding-up, liquidation or reorganization for the purposes of this
Section  if such  other  corporation  shall,  as a part  of such  consolidation,
merger,  conveyance or transfer, comply with the conditions stated in Article 5.
Nothing in this  Section  shall apply to claims of, or payments  to, the Trustee
under or pursuant to Article 7, except as provided  therein.  This Section shall
be subject to the further provisions of Section 11.5.

     SECTION 11.3. Subrogation of Securities.  Subject to the payment in full of
all  Senior and  Subordinated  Debt,  the  holders  of the  Securities  shall be
subrogated  to the  rights of the  holders of Senior  and  Subordinated  Debt to
receive payments or distributions of cash, property or securities of the Company
applicable  to the  Senior and  Subordinated  Debt  until the  principal  of and
interest on the Securities  shall be paid in full; and, for the purposes of such
subrogation,  no  payments  or  distributions  to the  holders of the Senior and
Subordinated  Debt of any cash,  property or  securities to which the holders of
the  Securities or the Trustee on their behalf would be entitled  except for the
provisions  of this Article,  and no payment over pursuant to the  provisions of
this  Article to the holders of Senior and  Subordinated  Debt by holders of the
Securities  or the Trustee on their behalf  shall,  as between the Company,  its
creditors other than holders of Senior and Subordinated  Debt and the holders of
the Securities, be deemed to be a payment by the Company to or on account of the
Senior and Subordinated Debt; and no payments or distributions of cash, property
or  securities  to or for the  benefit of the  Securityholders  pursuant  to the
subrogation  provision of this Article,  which would otherwise have been paid to
the holders of Senior and  Subordinated  Debt shall be deemed to be a payment by
the Company to or for the account of the  Securities.  It is understood that the
provisions  of this  Article  are and are  intended  solely  for the  purpose of
defining the relative rights of the holders of the Securities,  on the one hand,
and the holders of the Senior and Subordinated Debt, on the other hand.

     Nothing  contained in this Article or elsewhere in this Indenture or in the
Securities is intended to or shall impair, as between the Company, its creditors
other than the holders of Senior and  Subordinated  Debt, and the holders of the
Securities,  the obligation of the Company, which is absolute and unconditional,
to pay to the holders of the  Securities  the  



                                      -67-


principal  of and interest on the  Securities  as and when the same shall become
due and  payable in  accordance  with their  terms,  or is  intended to or shall
affect the relative rights of the holders of the Securities and creditors of the
Company other than the holders of the Senior and  Subordinated  Debt,  nor shall
anything  herein or therein prevent the holder of any Security or the Trustee on
his behalf from  exercising all remedies  otherwise  permitted by applicable law
upon default under this  Indenture,  subject to the rights,  if any,  under this
Article  of the  holders  of Senior  and  Subordinated  Debt in respect of cash,
property or  securities  of the Company  received  upon the exercise of any such
remedy.

     Upon any payment or  distribution  of assets of the Company  referred to in
this Article,  the Trustee,  subject to the  provisions of Sections 7.1 and 7.2,
and the  holders of the  Securities  shall be entitled to rely upon any order or
decree made by any court of competent  jurisdiction  in which such  liquidation,
dissolution, winding up, receivership, reorganization, assignment or marshalling
proceedings  are  pending,  or  a  certificate  of  the  receiver,   trustee  in
bankruptcy,  liquidating  trustee,  agent or other person making such payment or
distribution,  delivered to the Trustee or to the holders of the Securities, for
the  purpose  of  ascertaining  the  persons  entitled  to  participate  in such
distribution,  the  holders  of the  Senior  and  Subordinated  Debt  and  other
indebtedness of the Company,  the amount thereof or payable thereon,  the amount
or amounts paid or distributed  thereon and all other facts pertinent thereto or
to this Article.

     SECTION 11.4.  Authorization by Securityholders.  Each holder of a Security
by his  acceptance  thereof  authorizes  the  Trustee in his behalf to take such
action as may be  necessary  or  appropriate  to  effectuate  the  subordination
provided in this Article and appoints the Trustee his  attorney-in-fact  for any
and all such purposes.

     SECTION  11.5.  Notice to Trustee.  The Company  shall give prompt  written
notice to the Trustee  and to any paying  agent of any fact known to the Company
which would prohibit the making of any payment of moneys to or by the Trustee or
any paying agent in respect of the Securities pursuant to the provisions of this
Article.  Regardless  of anything to the  contrary  contained in this Article or
elsewhere in this Indenture,  the Trustee shall not be charged with knowledge of
the existence of any Senior and Subordinated  Debt or of any default or event of
default with respect to any Senior and  Subordinated  Debt or of any other facts
which would  prohibit  the making of any payment of moneys to or by the Trustee,
unless  and until the  Trustee  shall  have  received  notice in  writing at its
prin-



                                      -68-


cipal Corporate Trust Office to that effect signed by an officer of the Company,
or by a holder or agent of a holder of Senior  and  Subordinated  Debt who shall
have been  certified by the Company or otherwise  established  to the reasonable
satisfaction  of the Trustee to be such holder or agent, or by the trustee under
any  indenture   pursuant  to  which  Senior  and  Subordinated  Debt  shall  be
outstanding,  and, prior to the receipt of any such written notice,  the Trustee
shall, subject to Sections 7.1 and 7.2, be entitled to assume that no such facts
exist; provided that if on a date at least three Business Days prior to the date
upon which by the terms  hereof any such  moneys  shall  become  payable for any
purpose  (including,  without  limitation,  the payment of the  principal of, or
interest on any  Security)  the Trustee  shall not have received with respect to
such  moneys  the notice  provided  for in this  Section,  then,  regardless  of
anything herein to the contrary, the Trustee shall have full power and authority
to receive  such moneys and to apply the same to the purpose for which they were
received,  and shall not be affected by any notice to the contrary  which may be
received by it on or after such prior date.

     Regardless  of anything to the contrary  herein,  nothing shall prevent (a)
any payment by the Company or the Trustee to the  Securityholders  of amounts in
connection  with a redemption of Securities if (i) notice of such redemption has
been given  pursuant to Article 3 prior to the receipt by the Trustee of written
notice as  aforesaid,  and (ii) such notice of  redemption  is given not earlier
than 60 days before the  redemption  date,  or (b) any payment by the Trustee to
the Securityholders of amounts deposited with it pursuant to Section 8.1.

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


                                      -69-


     SECTION  11.6.  Trustee's  Relation to Senior and  Subordinated  Debt.  The
Trustee and any agent of the Company or the Trustee shall be entitled to all the
rights set forth in this  Article  with  respect to any Senior and  Subordinated
Debt which may at any time be held by it in its individual or any other capacity
to the same  extent as any other  holder of  Senior  and  Subordinated  Debt and
nothing in this Indenture shall deprive the Trustee or any such agent, of any of
its rights as such holder.  Nothing in this Article shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 7.7.

     With respect to the holders of Senior and  Subordinated  Debt,  the Trustee
undertakes to perform or to observe only such of its  covenants and  obligations
as are  specifically  set forth in this  Article,  and no implied  covenants  or
obligations with respect to the holders of Senior and Subordinated Debt shall be
read into this Indenture against the Trustee. The Trustee shall not be deemed to
owe any  fiduciary  duty to the  holders  of Senior and  Subordinated  Debt and,
subject to the  provisions  of Sections  7.1 and 7.2,  the Trustee  shall not be
liable to any  holder of Senior  and  Subordinated  Debt if it shall pay over or
deliver to holders of  Securities,  the  Company or any other  person  moneys or
assets to which any holder of Senior and Subordinated  Debt shall be entitled by
virtue of this Article or otherwise.

                  SECTION 11.7. No Impairment of Subordination.  No right of any
present  or  future  holder  of any  Senior  and  Subordinated  Debt to  enforce
subordination  as herein  provided shall at any time in any way be prejudiced or
impaired  by any act or failure to act on the part of the  Company or by any act
or failure to act, in good faith, by any such holder, or by any noncompliance by
the  Company  with  the  terms,  provisions  and  covenants  of this  Indenture,
regardless of any knowledge  thereof which any such holder may have or otherwise
be charged with.
