the Outstanding  Securities of all series or one or more series, as the case may
be, may be embodied in and evidenced by one or more instruments of substantially
similar tenor signed by such Holders in person or by an agent duly  appointed in
writing. Except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments or record or both are delivered to
the Trustee and, where it is hereby  expressly  required,  to the Company.  Such
instrument or instruments and any such record (and the action  embodied  therein
and  evidenced  thereby)  are herein  sometimes  referred to as the "Act" of the
Holders  signing  such  instrument  or  instruments  and so  voting  at any such
meeting.  Proof of execution of any such  instrument or of a writing  appointing
any such agent, or the holding of any Person of a Security,  shall be sufficient
for any purpose of this  Indenture and (subject to Section  6.01)  conclusive in
favor of the Trustee  and the  Company,  if made in the manner  provided in this
Section 1.05. The record of any meeting of Holders of Securities shall be proved
in the manner provided in Section 15.06.

     The Company may set a record date for purposes of determining  the identity

those Persons who were Holders of Outstanding Securities at such record date (or
their duly designated proxies),  and only those Persons,  shall be entitled with


                                       10


respect to such  Securities  to take such action by vote or consent or to revoke
any vote or consent previously given, whether or not such Persons continue to be
Holders after such record date.  Promptly  after any record date is set pursuant
to this paragraph,  the Company, at its own expense,  shall cause notice thereof
to be given to the Trustee in writing in the manner provided in Section 1.06 and
to the relevant Holders as set forth in Section 1.07.

     (b) The fact and date of the execution by any Person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by a
certificate  of a notary  public  or  other  officer  authorized  by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof. Where such execution is by
a  signer  acting  in a  capacity  other  than  his  individual  capacity,  such
certificate  or  affidavit  shall  also  constitute   sufficient  proof  of  his
authority. The fact and date of the execution of any such instrument or writing,
or the  authority of the Person  executing  the same,  may also be proved in any
other manner which the Trustee deems sufficient.

     (c) The  principal  amount and serial  numbers  of  Securities  held by any
Person,  and the date of  holding  the same,  shall be  proved  by the  Security
Register.

Securities have given any request,  demand,  authorization,  direction,  notice,
consent or waiver  under this  Indenture,  the  principal  amount of an Original
Issue  Discount  Security that may be counted in making such  determination  and
that shall be deemed to be  Outstanding  for such purposes shall be equal to the
amount of the principal thereof that would be due and payable upon a declaration
of acceleration of the Maturity thereof pursuant to Section 5.02 at the time the
taking of such  action by the  Holders  of such  requisite  principal  amount is
evidenced to the Trustee for such Securities.

     (e) Any request, demand, authorization,  direction, notice, consent, waiver
or other Act of the Holder of any Security shall bind every future Holder of the
same Security and the Holder of every Security  issued upon the  registration of
transfer  thereof  or in  exchange  therefor  or in lieu  thereof  in respect of
anything  done,  omitted or suffered to be done by the Trustee or the Company in
reliance  thereon,  whether  or not  notation  of such  action is made upon such
Security.  Any  consent  or  waiver  of the  Holder  of any  Security  shall  be
irrevocable for a period of six months after the date of execution thereof,  but
otherwise any such Holder or subsequent  Holder may revoke the request,  demand,
authorization,  direction,  notice,  consent or other Act as to his  Security or
portion  of his  Security;  provided,  however,  that such  revocation  shall be
effective only if the Trustee receives the notice of revocation  before the date
the Act becomes effective.

                                       11


     (1) the Trustee by any Holder or by the  Company  shall be  sufficient  for
every purpose hereunder if made, given, furnished or filed in writing to or with
the     Trustee     at    its     Corporate     Trust     Office,     Attention:
[________________________], or

     (2) the Company by the  Trustee or by any Holder  shall be  sufficient  for
every purpose  hereunder  (unless  otherwise  herein  expressly  provided) if in
writing and mailed, certified or registered mail (return receipt requested),  to

Section 1.07      Notice to Holders; Waiver.
                  --------------------------

     Where this  Indenture  provides for notice to Holders of  Securities of any
event,  such  notice  shall  be  sufficiently  given  (unless  otherwise  herein
expressly  provided) if in writing and mailed,  first-class  postage prepaid, to
each Holder  affected by such event, at the address of such Holder as it appears
in the Security  Register,  not later than the latest date, and not earlier than
the earliest date, prescribed for the giving of such notice.

     In case by reason of the  suspension of regular mail service,  or by reason
of any other cause it shall be  impracticable  to give such notice to Holders of
Securities by mail, then such notification as shall be made with the approval of
the  Trustee  shall  constitute  a  sufficient  notification  for every  purpose
hereunder.  In any case in which  notice to  Holders of  Securities  is given by
mail,  neither the failure to mail such notice,  nor any defect in any notice so
mailed, to any particular Holder of a Security,  shall affect the sufficiency of
such notice with respect to other Holders of Securities.

     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.

Section 2.03      Securities Issuable in the Form of a Global Security.
                  -----------------------------------------------------

     (a) If the  Company  shall  establish  pursuant  to  Section  3.01 that the
Securities  of a  particular  series are to be issued in whole or in part in the
form of one or more Global  Securities,  then the Company  shall execute and the
Trustee shall,  in accordance  with Section 3.03 and the Company Order delivered
to the Trustee  thereunder,  authenticate  and deliver  such Global  Security or
Securities,  which (i) shall  represent,  and shall be denominated in, an amount
equal to the aggregate  principal  amount of the Outstanding  Securities of such
series to be represented by such Global Security or Securities, (ii) may provide
that the aggregate amount of Outstanding Securities represented thereby may from
time to time be  increased  or  reduced  to reflect  exchanges,  (iii)  shall be
registered in the name of the Depositary for such Global  Security or Securities
or its  nominee,  (iv) shall be delivered  by the Trustee to the  Depositary  or
pursuant  to the  Depositary's  instruction  and  (v)  shall  bear a  legend  in
accordance with the requirements of the Depositary.

     (b)  Notwithstanding  any provision of Section 3.05, except as contemplated
by the  provisions of Section  2.03(c) or unless the terms of a Global  Security
expressly  permit such Global  Security to be  exchanged in whole or in part for
individual definitive Securities, a Global Security may be transferred, in whole
but not in part and in the manner provided in Section 3.05, only to a nominee of
the Depositary for such Global Security, or to the Depositary, or to a successor
Depositary for such Global Security selected or approved by the Company, or to a
nominee of such successor Depositary.

     (c) (1) If at any time the  Depositary for a Global  Security  notifies the
Company that it is unwilling  or unable to continue as the  Depositary  for such
Global  Security or if at any time the  Depositary  for the  Securities for such
series shall no longer be eligible or in good  standing  under the Exchange Act,
or other applicable statute or regulation, the Company shall appoint a successor
Depositary with respect to such Global Security.  If a successor  Depositary for
such Global  Security is not  appointed by the Company  within 90 days after the
Company receives such notice or becomes aware of such ineligibility, the Company
will  execute,  and  the  Trustee,  upon  receipt  of a  Company  Order  for the
authentication  and  delivery  of  Securities  of  such  series  in the  form of
definitive  certificates in exchange for such Global Security, will authenticate
and deliver Securities of such series in the form of definitive  certificates of
like tenor and terms in an aggregate  principal  amount  equal to the  principal
amount of the  Global  Security  in  exchange  for such  Global  Security.  Such
Securities  will be  issued  to and  registered  in the name of such  Person  or
Persons as are specified by the Depositary.

     (2) The Company may at any time and in its sole  discretion  determine that
the  Securities  of any  series  issued or  issuable  in the form of one or more
Global  Securities  shall no longer be  represented  by such Global  Security or
Securities.  In any such event the Company will execute,  and the Trustee,  upon
receipt of a Company Request for the  authentication  and delivery of Securities
in the form of definitive  certificates in exchange in whole or in part for such
Global  Security,  will  authenticate and deliver without service charge to each
Person  specified  by the  Depositary  Securities  in  the  form  of  definitive
certificates of like tenor and terms in an aggregate  principal  amount equal to


                                       15


the principal amount of such Global Security  representing  such series,  or the
aggregate  principal amount of such Global Securities  representing such series,
in exchange for such Global Security or Securities.

     (3) If  specified  by the Company  pursuant to Section 3.01 with respect to
Securities  issued or issuable in the form of a Global Security,  the Depositary
for such Global Security may surrender such Global Security in exchange in whole
or in part for Securities in the form of definitive  certificates  of like tenor
and terms 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, (A) to each Person specified by such Depositary
a new Security or  Securities of the same series of like tenor and terms and any
authorized  denomination  as  requested  by such Person in  aggregate  principal
amount equal to and in exchange  for such  Person's  beneficial  interest in the
Global  Security and (B) to such  Depositary a new Global Security of like tenor
and terms and in an authorized  denomination  equal to the  difference,  if any,
between  the  principal  amount  of the  surrendered  Global  Security  and  the
aggregate principal amount of Securities delivered to Holders thereof.

     (4)  In  any  exchange   provided  for  in  any  of  the  preceding   three
subparagraphs,  the Company shall execute and the Trustee shall authenticate and
deliver  Securities  in  the  form  of  definitive  certificates  in  authorized
denominations.  Upon the  exchange  of the entire  principal  amount of a Global
Security for  Securities  in the form of  definitive  certificates,  such Global
Security shall be canceled by the Trustee. Except as provided in the immediately
preceding subparagraph, Securities in the form of definitive certificates issued
in exchange for a Global  Security  pursuant to this Section shall be registered
in such names and in such  authorized  denominations  as the Depositary for such
Global  Security,  acting pursuant to  instructions  from its direct or indirect
participants or otherwise, shall instruct the Trustee. Provided that the Company
and the Trustee have so agreed, the Trustee shall deliver such Securities to the
Persons in whose names the Securities are so to be registered.

     (5) Any  endorsement of a Global  Security to reflect the principal  amount
thereof, or any increase or decrease in such principal amount, or changes in the
rights of Holders of Outstanding Securities represented thereby shall be made in
such manner and by such Person or Persons as shall be  specified  in or pursuant
to any applicable letter of  representations  or other arrangement  entered into
with, or procedures of, the Depositary  with respect to such Global  Security or
in the Company Order delivered or to be delivered  pursuant to Section 3.03 with
respect  thereto.  Subject to the  provisions of Section 3.03, the Trustee shall
deliver  and  redeliver  any  such  Global  Security  in  the  manner  and  upon
instructions  given by the Person or Persons  specified  in or  pursuant  to any
applicable letter of representations or other arrangement  entered into with, or
procedures  of, the  Depositary  with respect to such Global  Security or in any
applicable  Company  Order.  If a Company  Order  pursuant to Section 3.03 is so
delivered,  any instructions by the Company with respect to such Global Security
contained  therein  shall  be in  writing  but  need  not be  accompanied  by or
contained in an Officer's  Certificate and need not be accompanied by an Opinion
of Counsel.

                                       16


     (6) The Depositary or, if there be one, its nominee, shall be the Holder of
a Global Security for all purposes under this Indenture;  and beneficial  owners
with  respect to such Global  Security  shall hold their  interests  pursuant to
applicable  procedures  of such  Depositary.  The  Company,  the Trustee and the
Security  Registrar  shall be  entitled  to deal  with such  Depositary  for all
purposes  of this  Indenture  relating to such Global  Security  (including  the
payment of principal,  premium,  if any, and interest  (including any Additional
Interest) and the giving of  instructions  or directions by or to the beneficial
owners of such Global  Security as the sole Holder of such Global  Security  and

or indirect participants in such Depositary).  None of the Company, the Trustee,
any Paying  Agent or the Security  Registrar  shall have any  responsibility  or
liability for any aspect of the records  relating to or payments made on account
of  beneficial  ownership  interests of a Global  Security in or pursuant to any
applicable letter of representations or other arrangement  entered into with, or
procedures  of, the  Depositary  with  respect to such  Global  Security  or for
maintaining,  supervising or reviewing any records  relating to such  beneficial
ownership interests.

Secretary  of the  Company  and  delivered  to the  Trustee  at or  prior to the
delivery of the Officers' Certificate setting forth the terms of the series.

Section 3.02      Denominations.
                  --------------

     The  Securities of each series shall be issuable in such  denominations  as
shall be specified as  contemplated  by Section 3.01. In the absence of any such
provisions with respect to the Securities of any series,  the Securities of such
series  denominated in Dollars shall be issuable in  denominations of $1,000 and
any integral multiple thereof.

     Unless  otherwise  provided as contemplated by Section 3.01 with respect to
any series of Securities,  any Securities of a series  denominated in a currency
other than Dollars shall be issuable in  denominations  that are the equivalent,
as determined by the Company by reference to the noon buying rate in The City of
New York for cable transfers for such currency  ("Exchange  Rate"), as such rate
is reported or otherwise made available by the Federal Reserve Bank of New York,
on the  applicable  issue date for such  Securities,  of $1,000 and any integral
multiple thereof.

Section 3.03      Execution, Authentication, Delivery and Dating.
                  -----------------------------------------------

     The  Securities  shall be executed on behalf of the Company by its Chairman
of the Board,  its  President,  its Treasurer or one of its Vice  Presidents and
attested by its Secretary or one of its Assistant Secretaries.  The signature of
any of these officers on the Securities may be manual or facsimile.

     Securities  bearing the manual or facsimile  signatures of individuals  who
were at any time the proper  officers  of the  Company  shall bind the  Company,
notwithstanding  that such  individuals  or any of them have ceased to hold such
offices prior to the  authentication  and delivery of such Securities or did not
hold such offices at the date of such Securities.

     At any time and from time to time after the  execution and delivery of this
Indenture,  the  Company may deliver  Securities  of any series  executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication  and delivery of such  Securities,  and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities as in this
Indenture provided and not otherwise.

                                       20


     If the form or terms of the Securities of a series have been established in
or pursuant to one or more Board  Resolutions  or any other method  permitted by
Sections 2.01 and Section 3.01, in authenticating such Securities, and accepting
the  additional  responsibilities  under  this  Indenture  in  relation  to such
Securities,  the Trustee  shall be entitled to receive,  and (subject to Section
6.01) shall be fully protected in relying upon, an Opinion of Counsel stating,

     (1) that the form of such  Securities  has been  established  in conformity
with the provisions of this Indenture;

     (2) that the terms of such Securities  have been  established in conformity
with the provisions of this Indenture; and

     (3) that such  Securities when  authenticated  and delivered by the Trustee
and issued by the Company in the manner and subject to any conditions  specified
in such Opinion of Counsel, will constitute legal, valid and binding obligations
of the Company,  enforceable  in  accordance  with their  terms,  except as such
enforcement is subject to the effect of (i) bankruptcy,  insolvency,  fraudulent
conveyance,  reorganization  or other laws  relating to or affecting  creditors'
rights  and (ii)  general  principles  of equity  (regardless  of  whether  such
enforcement is considered in a proceeding in equity or at law).

     If not all the  Securities  of any series are to be issued at one time,  it
shall not be necessary to deliver the Officers' Certificate required pursuant to
Section  3.01 or the Company  Order or Opinion of Counsel  required  pursuant to
Section 3.03 at the time of issuance of each Security,  but such  documents,  as
applicable,  with appropriate  modifications shall be delivered at or before the
time of issuance of the first Security of such series.  The Trustee shall not be
required  to  authenticate  such  Securities  if the  issue  of such  Securities
pursuant to this  Indenture  will  affect the  Trustee's  own rights,  duties or
immunities  under the Securities and this Indenture or otherwise in a manner not
reasonably acceptable to the Trustee.

     Each Security shall be dated the date of its authentication.

     No Security  shall be entitled to any benefit  under this  Indenture  or be
valid or  obligatory  for any purpose  unless there  appears on such  Security a
certificate  of  authentication  substantially  in the form  provided for herein
executed  by the  Trustee by manual  signature,  and such  certificate  upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has  been  duly  authenticated  and  delivered  hereunder.  Notwithstanding  the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the  Company,  and the Company  shall  deliver such
Security to the Trustee for  cancellation  as provided in Section 3.09  together
with a written  statement  (which need not comply with Section 1.03 and need not
be  accompanied  by an Opinion of Counsel)  stating that such Security has never
been issued and sold by the  Company,  for all purposes of this  Indenture  such
Security  shall  be  deemed  never  to have  been  authenticated  and  delivered
hereunder and shall never be entitled to the benefits of this Indenture.

                                       21


     In case the  Company,  pursuant to and in  compliance  with  Article  Eight
hereof,  shall  consolidate  with or merge  into any  other  Person  or  convey,
transfer or lease its properties and assets  substantially as an entirety to any
Person, and the successor Person resulting from such consolidation, or surviving
such  merger,  or into which the Company  will have been  merged,  or the Person
which  will  have  received  a  sale,  conveyance,   transfer,  lease  or  other
disposition as aforesaid,  will have executed an indenture  supplemental  hereto
with the  Trustee  pursuant  to  Article  Eight  hereof,  any of the  Securities
authenticated   or  delivered  prior  to  such  sale,   consolidation,   merger,
conveyance,  transfer, lease or other disposition may, from time to time, at the
request of the successor  Person be exchanged for other  Securities  executed in
the name of the successor  Person with such changes in  phraseology  and form as
may be  appropriate,  but otherwise in substance of like tenor as the Securities
surrendered  for such exchange and of like  principal  amount;  and the Trustee,
upon Company  Request of the successor  Person,  will  authenticate  and deliver
Securities  as specified in such  request for the purpose of such  exchange.  If
Securities will at any time be authenticated  and delivered in any new name of a
successor  Person pursuant to this Section 3.03 in exchange or substitution  for
or upon  registration of transfer of any Securities,  such successor  Person, at
the option of the  Holders  but without  expense to them,  will  provide for the
exchange of all Securities at the time Outstanding for Securities  authenticated
and delivered in such new name.

Section 3.04      Temporary Securities.
                  ---------------------

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

     Except in the case of temporary  Securities  in global form (which shall be
exchanged in accordance  with the  provisions of the following  paragraphs),  if
temporary Securities of any series are issued, the Company will cause definitive
Securities of that series to be prepared without  unreasonable  delay. After the
preparation of definitive Securities of such series, the temporary Securities of
such series shall be exchangeable for definitive  Securities of such series upon
surrender of the temporary  Securities of such series at the office or agency of
the Company in a Place of Payment for that series, without charge to the Holder.
Upon surrender for  cancellation of any one or more temporary  Securities of any
series,  the Company shall execute and deliver a Company  Order  requesting  the
Trustee to  authenticate  and  deliver and the Trustee  shall  authenticate  and
deliver in exchange therefor a like principal amount of definitive Securities of
the same series of  authorized  denominations.  Until so exchanged the temporary
Securities  of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of such series.

                                       22


     All Outstanding temporary Securities of any series shall in all respects be
entitled to the same benefits under this  Indenture as definitive  Securities of
the same series and of like tenor authenticated and delivered hereunder.

Section 3.05      Registration, Registration of Transfer and Exchange.
                  ----------------------------------------------------

     The Company  shall cause to be kept for each series of Securities at one of
the offices or agencies  maintained  pursuant to Section  10.02 a register  (the
register  maintained  in such  office  and in any other  office or agency of the
Company in a Place of Payment being herein sometimes collectively referred to as
the "Security Register") in which, subject to such reasonable  regulations as it
may prescribe,  the Company shall provide for the registration of Securities and
of  transfers of  Securities  of such  series.  The Trustee is hereby  initially
appointed  "Security  Registrar" for the purpose of  registering  Securities and
transfers of Securities as herein provided.

     Except as set  forth in  Section  2.03 or as may be  provided  pursuant  to
Section 3.01, upon surrender for registration of transfer of any Security of any
series  at the  office  or agency in a Place of  Payment  for that  series,  the
Company  shall  execute and deliver a Company  Order  requesting  the Trustee to
authenticate and deliver and the Trustee shall authenticate and deliver,  in the
name of the designated transferee or transferees,  one or more new Securities of
the same series and of like tenor, of any authorized denominations and of a like
aggregate principal amount.

     At the option of the Holder,  Securities of any series may be exchanged for
other  Securities  of the  same  series  and of like  tenor,  of any  authorized
denominations and of a like aggregate  principal  amount,  upon surrender of the
Securities to be exchanged at such office or agency,  and upon  payment,  if the
Company  shall so require,  of the charges  hereinafter  provided.  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  Securities  issued  upon any  registration  of transfer or exchange of
Securities  shall be the valid  obligations of the Company,  evidencing the same
debt, and entitled to the same benefits under this Indenture,  as the Securities
surrendered upon such registration of transfer or exchange.

     Every Security presented or surrendered for registration of transfer or for
exchange  shall (if so required by the Company or the Trustee) be duly endorsed,
or be accompanied by a written  instrument of transfer in form  satisfactory  to
the Company and the Security  Registrar duly executed,  by the Holder thereof or
his attorney duly authorized in writing.

     No  service  charge  shall  be made for any  registration  of  transfer  or
exchange of Securities,  but 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 registration of transfer or exchange of Securities, other than exchange
pursuant to Section 3.04, 9.06 or 11.07 not involving any transfer.

                                       23


     The Company shall not be required (i) to issue, register the transfer of or
exchange  Securities of any series  during a period  beginning at the opening of
business  15 days  before the day of the  mailing of a notice of  redemption  of
Securities  of such series  selected for  redemption  and ending at the close of
business on the day of the mailing of the relevant notice of redemption, (ii) to
register the transfer of or exchange any Security so selected for  redemption in
whole or in part,  except the unredeemed  portion of any Security being redeemed
in part or (iii) to register  the transfer or exchange of  Securities  between a
record date and the next succeeding interest payment date.

     Any  Holder  of a Global  Security  shall,  by  acceptance  of such  Global
Security,  agree that transfers of beneficial  interests in such Global Security
may be effected  only  through a book entry system  maintained  by the Holder of
such Global Security (or its agent), and that ownership of a beneficial interest
in the Security shall be required to be reflected in a book entry.

Section 3.06      Mutilated, Destroyed, Lost and Stolen Securities.
                  -------------------------------------------------

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

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

     In case any such mutilated,  destroyed,  lost or stolen Security has become
or is about to become  due and  payable,  the  Company  in its  discretion  may,
instead of issuing a new Security, pay such Security.

     Upon the issuance of any new Security  under this Section 3.06, the Company
may  require  the  payment  of a sum  sufficient  to  cover  any  tax  or  other
governmental  charge  that may be  imposed  in  relation  thereto  and any other
expenses (including the fee and expenses of the Trustee) connected therewith.

     Every new  Security of any series  issued  pursuant to this Section 3.06 in
lieu of any  destroyed,  lost or stolen  Security  shall  constitute an original
additional contractual obligation of the Company,  whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall be


                                       24


entitled to all the benefits of this Indenture equally and proportionately  with
any and all other Securities of that series duly issued hereunder.

     The  provisions of this Section 3.06 are  exclusive and shall  preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities.

Section 3.07      Payment of Interest; Interest Rights Preserved.
                  -----------------------------------------------

     Interest on any Security which is payable,  and is punctually  paid or duly
provided for, on any Interest  Payment Date or within five days thereafter shall
be paid to the Person in whose name that  Security  (or one or more  Predecessor
Securities)  is registered  at the close of business on the Regular  Record Date
for such interest.  Unless otherwise  provided with respect to the Securities of
any  series,  payment of  interest  may be made at the option of the  Company by
check mailed or delivered to the address of any Person entitled  thereto as such
address shall appear in the Security Register.

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

     (1) The Company may elect to make payment of any Defaulted  Interest to the
Persons  in whose  names the  Securities  of such  series  (or their  respective
Predecessor  Securities)  are  registered  at the close of business on a Special
Record Date for the payment of such Defaulted Interest,  which shall be fixed in
the  following  manner.  The Company  shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on each Security of such series
and the date of the  proposed  payment,  and at the same time the Company  shall
deposit  with the  Trustee  an amount  of money  equal to the  aggregate  amount
proposed  to be paid in  respect  of  such  Defaulted  Interest  or  shall  make
arrangements  satisfactory  to the Trustee for such deposit prior to the date of
the  proposed  payment,  such money when  deposited  to be held in trust for the
benefit of the Persons entitled to such Defaulted Interest as in this clause (1)
provided.  Thereupon the Trustee shall fix a Special Record Date for the payment
of such  Defaulted  Interest  which  shall be not more than 15 days and not less
than 10 days prior to the date of the proposed payment and not less than 10 days
after the  receipt by the  Trustee of the notice of the  proposed  payment.  The
Trustee shall  promptly  notify the Company of such Special  Record Date and, in
the name and at the expense of the  Company,  shall cause notice of the proposed
payment of such  Defaulted  Interest and the Special  Record Date therefor to be
mailed, first-class postage prepaid, to each Holder of Securities of such series
at his  address as it appears in the  Security  Register,  not less than 10 days
prior to such  Special  Record  Date.  Notice of the  proposed  payment  of such
Defaulted  Interest and the Special Record Date therefor  having been so mailed,
such  Defaulted  Interest  shall  be paid to the  Persons  in  whose  names  the
Securities  of such  series (or their  respective  Predecessor  Securities)  are


                                       25


registered  at the close of  business on such  Special  Record Date and shall no
longer be payable pursuant to the following clause (2).

     (2)  The  Company  may  make  payment  of  any  Defaulted  Interest  on the
Securities  of any series in any other lawful manner not  inconsistent  with the
requirements of any securities  exchange on which such Securities may be listed,
and upon such notice as may be required by such exchange, if, after notice given
by the Company to the Trustee of the  proposed  payment  pursuant to this clause
(2), such manner of payment shall be deemed practicable by the Trustee.

     Subject to the foregoing  provisions  of this Section  3.07,  each Security
delivered under this Indenture, upon registration of transfer of, or in exchange
for or in lieu of, any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

Section 3.08      Persons Deemed Owners.
                  ----------------------

     Prior to due presentment of a Security for  registration  of transfer,  the
Company, the Security Registrar, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name such  Security is  registered  as the
owner of such  Security  for the purpose of receiving  payment of principal  of,
premium  (if any) and  (subject  to  Sections  3.05 and 3.07)  interest  on such
Security and for all other purposes whatsoever,  whether or not such Security be
overdue,  and neither the Company,  the Security Registrar,  the Trustee nor any
agent of the Company or the Trustee shall be affected by notice to the contrary.

Section 3.09      Cancellation.
                  -------------

     All  Securities  surrendered  for  payment,  redemption,   registration  of
transfer or exchange or for credit  against any sinking fund payment  shall,  if
surrendered  to any Person other than the Trustee,  be delivered to the Trustee.
All  Securities  so delivered  shall be promptly  canceled by the  Trustee.  The
Company may at any time deliver to the Trustee for  cancellation  any Securities
previously  authenticated  and  delivered  hereunder  which the Company may have
acquired in any manner  whatsoever,  and all  Securities  so delivered  shall be
promptly  canceled by the Trustee.  No Securities shall be authenticated in lieu
of or in exchange for any Securities  canceled as provided in this Section 3.09,
except as expressly permitted by this Indenture. All canceled Securities held by
the Trustee shall be disposed of by the Trustee in accordance with its customary
procedures, unless the Trustee is otherwise directed by a Company Order.

Section 3.10      Computation of Interest.
                  ------------------------

     Except  as  otherwise   specified  as  contemplated  by  Section  3.01  for
Securities  of any series,  interest on the  Securities  of each series shall be
computed on the basis of a year comprising twelve 30-day months.

                                       26


Section 3.11      CUSIP Numbers.
                  --------------

     The Company in issuing  the  Securities  may use  "CUSIP"  numbers (if then
generally in use),  and, if so, the Trustee shall use "CUSIP" numbers in notices
of  redemption as a  convenience  to Holders;  provided that any such notice may
state  that no  representation  is made as to the  correctness  of such  numbers
either  as  printed  on  the  Securities  or as  contained  in any  notice  of a
redemption  and that  reliance  may be placed  only on the other  identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers.  The Company will promptly  notify
the Trustee of any change in the CUSIP numbers.

                                  ARTICLE FOUR

                           SATISFACTION AND DISCHARGE

Section 4.01      Satisfaction and Discharge of Indenture.
                  ----------------------------------------

     This  Indenture  shall upon Company  Request cease to be of further  effect
with respect to Securities of a series,  and the Trustee,  at the expense of the
Company,  shall  execute  proper  instruments  acknowledging   satisfaction  and
discharge of this Indenture with respect to Securities of such series, when

     (1) either

     (A) all Securities of such series  theretofore  authenticated and delivered
(other than (i)  Securities  that have been  destroyed,  lost or stolen and that
have been replaced or paid as provided in Section 3.06, and (ii)  Securities for
whose payment money or Governmental  Obligations have theretofore been deposited
in trust with the Trustee or any Paying Agent or segregated and held in trust by
the Company and thereafter  repaid or returned to the Company or discharged from
such trust, as provided in Section 10.03) have been delivered to the Trustee for
cancellation;

     (B)  with  respect  to  all  Outstanding  Securities  of  such  series  not
theretofore delivered to the Trustee for cancellation, the Company has deposited
or caused to be deposited with the Trustee under the terms of a trust  agreement
in form and  substance  satisfactory  to the  Trustee,  as trust  funds in trust
solely  for the  benefit  of the  Holders  of  Outstanding  Securities  for that
purpose,  money or Government  Obligations maturing as to principal and interest
in such  amounts and at such times as will,  together  with the income to accrue
thereon, without consideration of any reinvestment thereof, be sufficient to pay
and  discharge the entire  indebtedness  on all  Outstanding  Securities of such
series not theretofore  delivered to the Trustee for  cancellation for principal
of, premium (if any) and interest on or any  Additional  Amounts with respect to
such Securities to the Stated  Maturity or any Redemption  Date  contemplated by
the penultimate paragraph of this Section 4.01, as the case may be; or

     (C) the Company has properly fulfilled such other means of satisfaction and
discharge as is specified,  as contemplated by Section 3.01, to be applicable to
the Securities of such series;

                                       27


     (2) the  Company  has paid or  caused  to be paid all  other  sums  payable
hereunder  by the Company  with respect to the  Outstanding  Securities  of such
series;

     (3) the Company has complied with any other conditions  specified  pursuant
to Section 3.01 to be applicable to the discharge of this Indenture with respect
to Securities of such series pursuant to this Section 4.01; and

     (4) the Company has delivered to the Trustee an Officers'  Certificate  and
an Opinion  of  Counsel,  each  stating  that all  conditions  precedent  herein
provided for relating to the  satisfaction  and discharge of this Indenture with
respect to the Securities of such series have been complied with;

     (5) if the  conditions  set forth in subclause (A) of clause (1) of Section
4.01 have not been satisfied and unless otherwise  specified pursuant to Section
3.01 for the Securities of such series, the Company has delivered to the Trustee
an  Opinion of Counsel to the  effect  that the  Holders of  Securities  of such
series will not recognize income,  gain or loss for United States federal income
tax purposes as a result of such deposit, satisfaction and discharge and will be
subject to United States  federal  income tax on the same amount and in the same
manner  and at the same  time as  would  have  been  the  case if such  deposit,
satisfaction and discharge had not occurred; and

     (6) no Default or Event of Default with respect to the  Securities  of such
issue shall have  occurred and be continuing on the date of any such deposit or,
in so far as clause (5) or (6) of Section 5.01 is concerned,  at any time in the
period  ending  on the  91st  day  after  the  date of such  deposit  (it  being
understood  that  this  condition  shall  not  be  deemed  satisfied  until  the
expiration of such period).

     If any  Outstanding  Securities of such series are to be redeemed  prior to
their Stated Maturity, whether pursuant to any optional redemption provisions or
in accordance with any mandatory sinking fund  requirement,  the trust agreement
referred to in subclause  (B) of clause (1) of this  Section 4.01 shall  provide
therefor and the Company shall make such arrangements as are satisfactory to the
Trustee for the giving of notice of redemption  by the Trustee in the name,  and
at the expense, of the Company.

     Notwithstanding  the  satisfaction  and  discharge of this  Indenture  with
respect to the  Securities  of such series  pursuant to this Section  4.01,  the
obligations of the Company to the Trustee under Section 6.07, the obligations of
the Company to any  Authenticating  Agent under Section 6.14 and the obligations
of the Trustee under Section 4.02 and the last  paragraph of Section 10.03 shall
survive.

Section 4.02      Application of Trust Money.
                  ---------------------------

     Subject to the provisions of the last paragraph of Section 10.03, all money
deposited  with the Trustee  pursuant to Section 4.01 shall be held in trust and
applied by it, in  accordance  with the  provisions of the  Securities  and this
Indenture,  to  the  payment,  either  directly  or  through  any  Paying  Agent
(including  the  Company  acting as its own  Paying  Agent) as the  Trustee  may
determine,  to the Persons  entitled  thereto,  of the principal of, premium (if
any) and interest on or any  Additional  Amounts with respect to  Securities  of


                                       28


such  series for the  payment of which  such money has been  deposited  with the
Trustee.

Section 4.03      Discharge of Liability on Securities of Any Series.
                  --------------------------------------------------

     If this Section 4.03 is specified,  as  contemplated by Section 3.01, to be
applicable to Securities of any series, the Company shall be deemed to have paid
and discharged the entire indebtedness on all the Outstanding Securities of such
series, the obligation of the Company under this Indenture and the Securities of
such series to pay the  principal  of,  premium (if any) and interest on and any
Additional  Amounts  with  respect to  Securities  of such series  shall  cease,
terminate and be completely  discharged,  and the Trustee, at the expense of the
Company,  shall execute proper  instruments  acknowledging such satisfaction and
discharge, when

     (1) the Company has complied  with the  provisions  of Section 4.01 of this
Indenture (other than any additional  conditions  specified  pursuant to Section
3.01 and  clause  (3) of Section  4.01 and  except  that the  Opinion of Counsel
referred  to in clause  (5) of Section  4.01  shall  state that it is based on a
ruling by the  Internal  Revenue  Service or other  change since the date hereof
under  applicable  Federal  income  tax law)  with  respect  to all  Outstanding
Securities of such series,

     (2) the Company has delivered to the Trustee a Company  Request  requesting
such satisfaction and discharge,

     (3) the Company has complied with any other conditions  specified  pursuant
to Section 3.01 to be  applicable  to the discharge of Securities of such series
pursuant to this Section 4.03, and

     (4) the Company has delivered to the Trustee an Officer's  Certificate  and
an Opinion  of  Counsel,  each  stating  that all  conditions  precedent  herein
provided  relating  to the  discharge  of the  indebtedness  on the  Outstanding
Securities of such series have been complied with.

     Upon the satisfaction of the conditions set forth in this Section 4.03 with
respect  to  all  the  Outstanding  Securities  of any  series,  the  terms  and
conditions  of such  series,  including  the terms and  conditions  with respect
thereto  set  forth in this  Indenture,  shall no  longer be  binding  upon,  or
applicable  to, the Company;  provided that, the Company shall not be discharged
from any payment  obligations  in respect of Securities of such series which are
deemed not to be  Outstanding  under clause (iii) of the  definition  thereof if
such  obligations  continue  to  be  valid  obligations  of  the  Company  under
applicable law or pursuant to Section 3.05 or Section 3.06.

Section 4.04.     Reinstatement.
                  -------------

     If the Trustee or Paying  Agent is unable to apply any money or  Government
Obligations  deposited  with respect to  Securities  of any series in accordance
with Section 4.01 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


                                       29


Indenture  with respect to the  Securities of such series and the  Securities of
such series  shall be revived and  reinstated  as though no deposit had occurred
pursuant  to  Section  4.01 until  such time as the  Trustee or Paying  Agent is
permitted to apply all such money or Government  Obligations in accordance  with
Section  4.01;  provided,  however,  that if the Company has made any payment of
principal  of,  premium (if any) or interest on or any  Additional  Amounts with
respect to 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  money or  Government  Obligations  held by the
Trustee or Paying Agent.

Section 5.01.     Events of Default.
                  -------------------

     "Event of Default,"  wherever used herein with respect to Securities of any
series,  means any one of the following  events which shall have occurred and be
continuing  (whatever  the reason for such Event of Default and whether it shall
be occasioned by the subordination provisions applicable to any Securities or be
voluntary  or  involuntary  or effected by  operation  of law or pursuant to any
judgment,  decree or order of any court or any order,  rule or regulation of any
administrative  or  governmental  body),  unless it is either  inapplicable to a
particular  series or it is  specifically  deleted or modified in or pursuant to
the  supplemental  indenture  or Board  Resolution  establishing  such series of
Securities or in the form of Security for such series:

     (1) default in the payment of any  interest  on or any  Additional  Amounts

default for a period of 30 days; or

     (4) default in the  performance or breach of any covenant of the Company in
this  Indenture  (other than a covenant a default in whose  performance or whose
breach is elsewhere in this  Section 5.01  specifically  dealt with or which has
expressly been included in this Indenture  solely for the benefit of one or more
series of Securities other than that series), and continuance of such default or
breach for a period of 60 days after  there has been  given,  by  registered  or
certified  mail, to the Company by the Trustee or to the Company and the Trustee
by the Holders of at least 25% in principal amount of all Outstanding Securities
a written  notice  specifying  such  default  or breach and  requiring  it to be
remedied and stating that such notice is a "Notice of Default" hereunder; or

                                       30


     (5) the  entry by a court  having  jurisdiction  in the  premises  of (A) a
decree or order for relief in respect of the Company in an  involuntary  case or
proceeding  under  any  applicable  federal  or  state  bankruptcy,  insolvency,
reorganization  or other  similar  law or (B) a decree  or order  adjudging  the
Company a bankrupt or  insolvent,  or  approving  as  properly  filed a petition
seeking reorganization,  arrangement, adjustment or composition of or in respect
of the  Company  under any  applicable  federal or state law,  or  appointing  a
custodian,  receiver,  liquidator,  assignee,  trustee,  sequestrator  or  other
similar official of the Company or of any substantial  part of its property,  or
ordering the winding up or  liquidation of its affairs,  and the  continuance of
any such decree or order for relief or any such other  decree or order  unstayed
and in effect for a period of 90 consecutive days; or

     (6) the commencement by the Company of a voluntary case or proceeding under
any applicable federal or state bankruptcy, insolvency,  reorganization or other
similar law or of any other case or proceeding  to be  adjudicated a bankrupt or
insolvent,  or the consent by it to the entry of a decree or order for relief in
respect of the Company in an involuntary case or proceeding under any applicable
federal or state bankruptcy, insolvency,  reorganization or other similar law or
to the  commencement of any bankruptcy or insolvency case or proceeding  against
it,  or  the  filing  by  it,  of  a  petition  or  answer  or  consent  seeking
reorganization  or relief  under any  applicable  federal or state  law,  or the
consent by it to the filing of such petition or to the  appointment of or taking
possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator
or similar  official of the Company or of any substantial  part of its property,
or the  making by it of an  assignment  for the  benefit  of  creditors,  or the
admission by it in writing of its  inability to pay its debts  generally as they
become due, or the taking of corporate  action by the Company in  furtherance of
any such action; or

     (7) any other Event of Default  provided with respect to Securities of that
series  in or  pursuant  to  the  supplemental  indenture  or  Board  Resolution
establishing  such  series of  Securities  or in the form of  Security  for such
series.

     Notwithstanding  the  foregoing  provisions  of this Section  5.01,  if the
principal of, premium (if any) or any interest on or any Additional Amounts with
respect to any  Security is payable in a currency  or  currencies  (including  a
composite  currency)  other than Dollars and such currency or currencies are not
available to the Company for making  payment  thereof due to the  imposition  of
exchange  controls or other  circumstances  beyond the control of the Company (a
"Conversion  Event"), the Company will be entitled to satisfy its obligations to
Holders of the  Securities  by making such payment in Dollars in an amount equal
to the Dollar  equivalent  of the amount  payable  in such  other  currency,  as
determined  by the Company by reference to the Exchange  Rate,  as such Exchange
Rate is certified for customs  purposes by the Federal  Reserve Bank of New York
on the date of such  payment,  or,  if such rate is not then  available,  on the
basis  of  the  most  recently  available  Exchange  Rate.  Notwithstanding  the
foregoing  provisions  of  this  Section  5.01,  any  payment  made  under  such
circumstances  in Dollars where the required payment is in a currency other than
Dollars will not constitute an Event of Default under this Indenture.

                                       31


     Promptly  after the  occurrence  of a Conversion  Event with respect to the
Securities of any series,  the Company shall give written  notice thereof to the
Trustee;  and the Trustee,  promptly  after  receipt of such notice,  shall give
notice  thereof in the manner  provided  in Section  1.07 to the Holders of such
series.  Promptly  after the  making of any  payment in Dollars as a result of a
Conversion Event with respect to the Securities of any series, the Company shall
give  notice in the  manner  provided  in  Section  1.07 to the  Holders of such
series,   setting  forth  the  applicable   Exchange  Rate  and  describing  the
calculation of such payments.

Section 5.02.     Acceleration of Maturity; Rescission and Annulment.
                  ---------------------------------------------------

     If an Event of Default with respect to any  Securities of any series at the
time Outstanding  occurs and is continuing,  then in every such case the Trustee
or the  Holders  of not  less  than 25% in  aggregate  principal  amount  of the
Outstanding  Securities of (i) the series with respect to which such default has
occurred,  in the case of an Event of Default described in clause (1), (2), (3),
(4) (if the Event of Default  under  clause (4) is with respect to less than all
series of  Securities  then  outstanding)  or (7) of Section  5.01,  or (ii) all
series of Securities, in the case of an Event of Default described in clause (4)
(if the Event of  Default  under  clause  (4) is with  respect  to all series of
Securities  then  outstanding),  (5) or (6) of Section  5.01,  may  declare  the
principal  amount  (or,  if any such  Securities  are  Original  Issue  Discount
Securities,  such  portion of the  principal  amount as may be  specified in the
terms of that  series) of all of the  Securities  of the series with  respect to
which such default has  occurred,  or all series,  as the case may be, to be due
and  payable  immediately,  by a notice in  writing to the  Company  (and to the
Trustee if given by Holders),  and upon any such  declaration  such amount shall
become immediately due and payable.

     At any time  after  such a  declaration  of  acceleration  with  respect to
Securities  of any series (or of all series,  as the case may be) has been made,
the Holders of a majority in principal  amount of the Outstanding  Securities of
that  series (or of all series,  as the case may be),  by written  notice to the
Company  and the  Trustee,  may  rescind  and  annul  such  declaration  and its
consequences if

     (1) the Company has paid or deposited  with the Trustee a sum sufficient to
pay

     (A) all overdue  interest on, and any  Additional  Amounts with respect to,
all Securities of that series (or of all series, as the case may be),

     (B) the unpaid  principal of and premium (if any) on any Securities of that
series (or of all series,  as the case may be) which have  become due  otherwise
than by such  declaration of  acceleration  and interest  thereon at the rate or
rates  prescribed  therefor in such  Securities  (in the case of Original  Issue
Discount Securities, the Securities' Yield to Maturity),

     (C) to the extent that payment of such  interest is lawful,  interest  upon
overdue  interest  and any  Additional  Amounts at the rate or rates  prescribed


                                       32


therefor in such Securities (in the case of Original Issue Discount  Securities,
the Securities' Yield to Maturity), and

     (D) all sums paid or advanced by the Trustee  hereunder,  the compensation,
expenses,  disbursements and advances due to Trustee under Section 6.07, and all
other amounts due under Section 6.07;

     (2) all Events of Default with respect to  Securities of that series (or of
all series,  as the case may be),  other than the nonpayment of the principal of
Securities  of that  series  (or of all  series,  as the case may be) which have
become due solely by such declaration of acceleration, have been cured or waived
as provided in Section 5.13; and

     (3) the rescission  would not conflict with any final judgment or decree of
a court of competent jurisdiction.

     No such rescission shall affect any subsequent  default or impair any right
consequent thereon.

Section 5.03.   Collection of Indebtedness and Suits for Enforcement by Trustee.
                ----------------------------------------------------------------

     The Company covenants that if

     (1) default is made in the payment of any  installment  of interest  on, or
any  Additional  Amounts  with  respect to, any Security of any series when such
interest  or  Additional  Amounts  shall have  become due and  payable  and such
default continues for a period of 30 days, or

     (2) default is made in the payment of the  principal of or premium (if any)
on any Security at the Maturity thereof,

the Company will, upon demand of the Trustee,  pay to it, for the benefit of the
Holders  of such  Securities,  the whole  amount  then due and  payable  on such
Securities  for principal of, premium (if any) and interest on or any Additional
Amounts with respect to such  Securities and, to the extent that payment of such
interest  shall be  legally  enforceable,  interest  on any  overdue  principal,
premium (if any) and on any overdue interest or Additional  Amounts, at the rate
or rates  prescribed  therefor  in such  Securities  (or in the case of Original
Issue Discount Securities,  the Securities' Yield to Maturity), and, in addition
thereto,  such  further  amount  as shall be  sufficient  to cover the costs and
expenses  of  collection,  including  the  reasonable  compensation,   expenses,
disbursements and advances of the Trustee, its agents and counsel, and all other
amounts due the Trustee under Section 6.07.

     If the Company fails to pay such amounts  forthwith  upon such demand,  the
Trustee,  in its own name and as trustee of an express  trust,  may  institute a
judicial  proceeding  for the  collection  of the  sums so due and  unpaid,  may
prosecute  such  proceeding to judgment or final decree and may enforce the same
against the Company or any other  obligor upon such  Securities  and collect the
moneys  adjudged  or decreed to be payable in the manner  provided by law out of


                                       33


the property of the Company or any other obligor upon such Securities,  wherever
situated.

     If an Event of Default with respect to  Securities of any series occurs and
is continuing,  the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the  Holders of  Securities  of such series by such
appropriate  judicial  proceedings  as the Trustee shall deem most  effectual to
protect and enforce any such rights, whether for the specific enforcement of any
covenant or agreement  in this  Indenture or in aid of the exercise of any power
granted herein, or to enforce any other proper remedy.

Section 5.04.     Trustee May File Proofs of Claim.
                  ---------------------------------

     In case  of the  pendency  of any  receivership,  insolvency,  liquidation,
bankruptcy,  reorganization,   arrangement,  adjustment,  composition  or  other
judicial  proceeding  relative  to the  Company  or any other  obligor  upon the
Securities  or the  property  of the  Company or of such other  obligor or their
creditors,  the Trustee (irrespective of whether the principal (or lesser amount
in the case of Original Issue Discount  Securities) of the Securities shall then
be due and payable as therein  expressed  or by  declaration  or  otherwise  and
irrespective  of whether the  Trustee  shall have made any demand on the Company
for the payment of overdue  principal of,  premium (if any),  interest on or any
Additional  Amounts  with  respect to such  Securities)  shall be  entitled  and
empowered, by intervention in such proceeding or otherwise,

     (1) to file and prove a claim for the whole amount of principal  (or lesser
amount in the case of Original Issue Discount  Securities) (and premium, if any)
and  interest  and any  Additional  Amounts  owing and  unpaid in respect of the
Securities  and to file such other  papers or  documents  as may be necessary or
advisable  to have the  claims  of the  Trustee  (including  any  claim  for the
reasonable  compensation,  expenses,  disbursements and advances of the Trustee,
its agents and counsel) and of the Holders allowed in such judicial  proceeding,
and

     (2) to  collect  and  receive  any  monies  or other  property  payable  or
deliverable  on any such claims and to distribute  the same;  and any custodian,
receiver, assignee, trustee, liquidator,  sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee  shall consent to the
making of such  payments  directly  to the  Holders,  to pay to the  Trustee any
amount  due it for the  reasonable  compensation,  expenses,  disbursements  and
advances of the Trustee,  its agents and counsel,  and any other amounts due the
Trustee under Section 6.07.

     Nothing  herein  contained  shall be deemed to  authorize  the  Trustee  to
authorize  or  consent 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 proceedings;  provided,  however,
that the  Trustee  may,  on behalf of the  Holders,  vote for the  election of a
trustee in bankruptcy or similar official.

Section 5.05.     Trustee May Enforce Claims Without Possession of
                  ------------------------------------------------
 Securities or Coupons.
- -----------------------

     All rights of action and claim under this  Indenture or the  Securities may
be  prosecuted  and  enforced by the Trustee  without  possession  of any of the
Securities or the production  thereof in any proceeding  relating  thereto;  any
such  proceeding  instituted  by the Trustee shall be brought in its own name as
trustee of an express trust;  after  provision for the payment of the reasonable
compensation,  expenses,  disbursements and advances of the Trustee,  its agents
and counsel,  and any other  amounts due the Trustee  under  Section  6.07,  any
recovery  of  judgment  shall be for the  ratable  benefit of the Holders of the
Securities in respect of which such judgment has been recovered.

Section 5.06.     Application of Money Collected.
                  -------------------------------

     Subject  to  the  subordination  provisions  applicable  to any  series  of
Securities,  any money  collected  by the Trustee  pursuant to this Article Five
shall be  applied  in the  following  order,  at the date or dates  fixed by the
Trustee and, in case of the  distribution  of such money on account of principal
of,  premium (if any) or interest on or any  Additional  Amounts with respect to
such Securities,  upon presentation of the Securities,  and the notation thereon
of the payment if only partially paid and upon surrender thereof if fully paid:

     FIRST: To the payment of all amounts due the Trustee under Section 6.07;

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

     THIRD: The balance, if any, to the Company.

     To the fullest extent allowed under  applicable  law, if for the purpose of
obtaining  judgment  against the Company in any court it is necessary to convert
the sum due in respect of the principal  of,  premium (if any) or interest on or
any  Additional  Amounts  with  respect to the  Securities  of 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 Business Day
in the City of New York next  preceding  that on which final  judgment is given.
Neither the Company nor the Trustee  shall be liable for any shortfall nor shall
it benefit  from any  windfall in payments to Holders of  Securities  under this
Section 5.06 caused by a change in exchange rates between the time the amount of


                                       35


a judgment  against it is calculated as above and the time the Trustee  converts
the Judgment  Currency into the Required  Currency to make  payments  under this
Section  5.06 to Holders of  Securities,  but  payment in full of such  judgment
shall  discharge  all  amounts  owed  by the  Company  on the  claim  or  claims
underlying such judgment.

Section 5.07.     Limitation on Suits.
                  --------------------

     Subject to Section 5.08, no Holder of any Security of any series shall have
any right to institute any  proceeding,  judicial or otherwise,  with respect to
this  Indenture,  or for the  appointment  of a receiver or trustee,  or for any
other remedy hereunder, unless

     (1) an Event of Default  with  respect to  Securities  of such series shall
have occurred and be  continuing  and such Holder has  previously  given written
notice to the Trustee of such continuing Event of Default;

     (2) the Holders of not less than 25% in principal amount of the Outstanding
Securities  of that  series  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;

     (3) such Holder or Holders have offered to the Trustee reasonable indemnity
against the costs,  expenses and  liabilities to be incurred in compliance  with
such request;

     (4) the Trustee for 60 days after its receipt of such  notice,  request and
offer of indemnity has failed to institute any such proceeding; and

     (5) no direction  inconsistent  with such written request has been given to
the Trustee  during such 60-day period by the Holders of a majority in principal
amount of the  Outstanding  Securities of that series (or of all series,  as the
case may be);

it being  understood and intended that no one or more of such Holders shall have
any right in any manner  whatever by virtue of, or by availing of, any provision
of this  Indenture to affect,  disturb or  prejudice  the rights of any other of
such Holders,  or to obtain or to seek to obtain priority or preference over any
other of such  Holders or to enforce any right under this  Indenture,  except in
the manner herein  provided and for the equal and ratable benefit of all of such
Holders.

Section 5.08.     Unconditional Right of Holders to Receive Principal,
                  ----------------------------------------------------
 Premium and Interest.
- ----------------------

     Notwithstanding  any other provision in this  Indenture,  the Holder of any
Security shall have the right, which is absolute and  unconditional,  to receive
payment of the  principal  of,  premium (if any) and  (subject to Section  3.07)
interest  on or any  Additional  Amounts  with  respect to such  Security on the
Stated  Maturity or  Maturities  expressed in such  Security (or, in the case of
redemption, on the Redemption Date) and to institute suit for the enforcement of
any such payment on or after such respective dates, and such rights shall not be
impaired or affected without the consent of such Holder.

Section 5.09.     Restoration of Rights and Remedies.
                  -----------------------------------

     If the Trustee or any Holder of any Security 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,  the  Company,  the
Trustee and the Holders shall,  subject to any determination in such proceeding,
be restored severally and respectively to their former positions hereunder,  and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

Section 5.10.     Rights and Remedies Cumulative.
                  -------------------------------

     Except as otherwise  provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of Section
3.06, 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 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 5.11.     Delay or Omission Not Waiver.
                  -----------------------------

     No delay or omission of the Trustee or of any Holder of any  Securities  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 Five 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.

Section 5.12.     Control by Holders.
                  -------------------

     With  respect to  Securities  of any  series,  the Holders of a majority in
aggregate  principal  amount of the Outstanding  Securities of such series shall
have the right to direct the time, method and place of conducting any proceeding
for any  remedy  available  to the  Trustee,  or  exercising  any trust or power
conferred  on the  Trustee,  relating  to or  arising  under an Event of Default
described in clause (1),  (2), (3) or (7) of Section  5.01,  and with respect to
all  Securities the Holders of a majority in aggregate  principal  amount of all
Outstanding Securities shall have the right to direct the time, method and place
of conducting  any remedy  available to the Trustee,  or exercising any trust or
power  conferred on the Trustee,  not relating to or arising under such an Event
of Default, provided that in each such case

     (1) the  Trustee  shall  have  the  right to  decline  to  follow  any such
direction if the Trustee,  being advised by counsel,  determines that the action
so directed may not lawfully be taken or would  conflict with this  Indenture or
if the Trustee in good faith shall, by a Responsible Officer, determine that the
proceedings so directed would involve it in personal  liability without adequate


                                       37


indemnity from such Holders or be unjustly prejudicial to the Holders not taking
part in such direction, and

     (2) the  Trustee  may take any other  action  deemed  proper by the Trustee
which is not inconsistent with such direction.

Section 5.13.     Waiver of Past Defaults.
                  ------------------------

     Subject to Sections  5.08 and 9.02,  the Holders of a majority in aggregate
principal  amount of the  Outstanding  Securities of any series may on behalf of
the  Holders  of all the  Securities  of such  series  waive  any  past  default
hereunder with respect to such series and its consequences, and the Holders of a
majority in aggregate  principal  amount of all  Outstanding  Securities  may on
behalf of the Holders of all Securities  waive any other past default  hereunder
and its consequences, except in each case a default

Outstanding Security affected.

     Upon any such waiver,  such default shall cease to exist,  and any Event of
Default 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 impair any right  consequent  thereon.  Any such waiver may (but need
not) be given in  connection  with a tender  offer  or  exchange  offer  for the

discretion require, in any suit for the enforcement of any right or remedy under
this  Indenture,  or in any suit  against the  Trustee  for any action  taken or
omitted by it as  Trustee,  the filing by any party  litigant in such suit of an
undertaking  to pay the  costs of such  suit,  and that  such  court  may in its

expenses,  against  any party  litigant  in such suit,  having due regard to the
merits and good faith of the claims or defenses made by such party litigant.

Section 5.15.     Waiver of Stay or Extension Laws.
                  ---------------------------------

     The Company  covenants  (to the extent that it may  lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage  of, any stay or extension  law wherever  enacted,
now or at any time  hereafter  in force,  which may affect the  covenants or the
performance  of this  Indenture;  and the  Company  (to the  extent  that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and  covenants  that it will not hinder,  delay or impede the  execution  of any


                                       38


power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

the Securities of any series,

     (1) the Trustee  undertakes  to perform such duties and only such duties as
are  specifically  set forth in this  Indenture,  and no  implied  covenants  or
obligations shall be read into this Indenture against the Trustee; and

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

     (b) In case an Event of Default has occurred and is continuing with respect
to the  Securities of any series,  the Trustee shall exercise such of the rights
and powers vested in it by this  Indenture,  and use the same degree of care and
skill in their  exercise,  as a prudent  person would  exercise or use under the
circumstances in the conduct of such person's own affairs.

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

     (3) this  Section  6.01(c)  shall not be  construed  to limit the effect of
Section 6.01(a);

faith by a Responsible  Officer,  unless it shall be proved that the Trustee was
negligent in  ascertaining  the  pertinent  facts;

omits to take in good faith in accordance with the direction of the Holders of a
majority in aggregate  principal  amount of the  Outstanding  Securities  of any

time,  method and place of conducting any proceeding for any remedy available to

the Trustee, or exercising any trust or power conferred upon the Trustee,  under
this Indenture with respect to the Securities of such series; and

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

     (d) 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 Section

Securities of such series,  the Trustee shall be protected in  withholding  such
notice if and so long as the board of directors,  the  executive  committee or a
trust  committee  of directors  or  Responsible  Officers of the Trustee in good
faith  determine  that the  withholding of such notice is in the interest of the
Holders of Securities of such series; and provided, further, that in the case of
any  Default  or Event of Default of the  character  specified  in clause (4) of
Section  5.01 with  respect to  Securities  of such  series,  no such  notice to

bankrupt or insolvent  or a receiver of the Trustee or of its property  shall be
appointed or any public  officer  shall take charge or control of the Trustee or
of its property or affairs for the purpose of  rehabilitation,  conservation  or
liquidation,  then, in any such case, (i) the Company by a Board  Resolution may
remove the Trustee  with respect to all  Securities,  or (ii) subject to Section
5.14,  any Holder who has been a bona fide Holder of a Security for at least six
months may, on behalf of himself and all others similarly situated, petition any
court of competent  jurisdiction  for the removal of the Trustee with respect to

such series and that at any time there shall be only one Trustee with respect to

instrument accepting such appointment,  and thereupon the resignation or removal
of the retiring  Trustee  shall become  effective  and such  successor  Trustee,
without any further act,  deed or  conveyance,  shall become vested with all the
rights,  powers,  trusts and duties of the retiring Trustee; but, on the request

confirm to, and to vest in,  each  successor  Trustee  all the  rights,  powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates,  (2)
if the retiring  Trustee is not retiring with respect to all  Securities,  shall
contain  such  provisions  as shall be deemed  necessary or desirable to confirm
that all the rights,  powers,  trusts and duties of the  retiring  Trustee  with
respect  to the  Securities  of that or those  series as to which  the  retiring
Trustee is not retiring shall continue to be vested in the retiring  Trustee and
(3) shall add to or change any of the  provisions of this  Indenture as shall be
necessary  to  provide  for or  facilitate  the  administration  of  the  trusts

in such supplemental indenture shall constitute such Trustees co-trustees of the
same  trust and that each such  Trustee  shall be  trustee  of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder  administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture,  the  resignation  or removal of the  retiring  Trustee  shall become
effective  to the  extent  provided  therein  and each such  successor  Trustee,
without any further act,  deed or  conveyance,  shall become vested with all the


                                       45

retiring  Trustee  shall duly  assign,  transfer  and deliver to such  successor
Trustee all  property and money held by such  retiring  Trustee  hereunder  with
respect to the  Securities of that or those series to which the  appointment  of
such successor Trustee relates.

to such  successor  Trustee all such  rights,  powers and trusts  referred to in
Section 6.11(a) or Section 6.11(b), as the case may be.

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

Section 6.12.     Merger, Conversion, Consolidation or Succession to Business.

conversion  or  consolidation  to which  the  Trustee  shall be a party,  or any
corporation  succeeding to all or substantially all the corporate trust business
of the Trustee,  shall be the successor of the Trustee hereunder,  provided such
corporation  shall be otherwise  qualified and eligible  under this Article Six,
without the  execution  or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not  delivered,  by the Trustee  then in office,  any  successor  by merger,
conversion  or  consolidation  to such  authenticating  Trustee  may adopt  such
authentication  and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself  authenticated  such Securities;  and in
case at that time any of the Securities shall not have been  authenticated,  any
successor  Trustee may  authenticate  such Securities  either in the name of any
predecessor  hereunder or in the name of the successor Trustee;  and in all such
cases such  certificates  shall have the full force  which it is anywhere in the
Securities or in this Indenture provided,  provided,  however, that the right to
adopt the certificate of  authentication  of any predecessor  Trustee will apply

and  all  applicable  provisions  of  the  Trust  Indenture  Act  regarding  the
collection of claims against the Company or such other obligor.

Section 6.14.     Appointment of Authenticating Agent.

authorized  to act on behalf of the Trustee to  authenticate  Securities  issued
upon  original  issue and upon  exchange,  registration  of  transfer or partial


                                       46


redemption or pursuant to Section 3.06, and Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the  authentication  and delivery of Securities by the
Trustee or the Trustee's certificate of authentication,  such reference shall be
deemed to include  authentication  and  delivery  on behalf of the Trustee by an
Authenticating  Agent and a certificate of authentication  executed on behalf of
the  Trustee by an  Authenticating  Agent.  Each  Authenticating  Agent shall be
acceptable to the Company and shall at all times be a corporation  organized and
doing business under the laws of the United States of America, any state thereof
or the District of Columbia,  having a combined  capital and surplus of not less
than $50  million or  equivalent  amount  expressed  in a foreign  currency  and
subject to  supervision  or  examination by federal or state (or the District of
Columbia) authority or authority of such country.  If such Authenticating  Agent
publishes  reports of  condition  at least  annually,  pursuant to law or to the
requirements of said supervising or examining  authority,  then for the purposes
of this Section 6.14,  the combined  capital and surplus of such  Authenticating
Agent shall be deemed to be its combined capital and surplus as set forth in its
most recent report of condition so published.  If at any time an  Authenticating
Agent  shall  cease to be eligible in  accordance  with the  provisions  of this
Section 6.14, such  Authenticating  Agent shall resign immediately in the manner
and with the effect specified in this Section 6.14.

     Any  corporation  into  which an  Authenticating  Agent  may be  merged  or
converted or with which it may be  consolidated,  or any  corporation  resulting
from any merger,  conversion or consolidation to which such Authenticating Agent
shall be a party,  or any  corporation  succeeding  to the  corporate  agency or
corporate  trust business of an  Authenticating  Agent,  shall continue to be an
Authenticating  Agent,  provided such  corporation  shall be otherwise  eligible
under this  Section  6.14,  without the  execution or filing of any paper or any
further act on the part of the Trustee or the Authenticating Agent.

     An  Authenticating  Agent may resign at any time by giving  written  notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an  Authenticating  Agent by giving written notice thereof to such
Authenticating  Agent  and to the  Company.  Upon  receiving  such a  notice  of
resignation  or  upon  such  a  termination,   or  in  case  at  any  time  such
Authenticating  Agent  shall  cease  to  be  eligible  in  accordance  with  the
provisions  of  this  Section   6.14,   the  Trustee  may  appoint  a  successor
Authenticating  Agent  which shall be  acceptable  to the Company and shall mail
written notice of such appointment by first-class mail, postage prepaid,  to all
Holders  as their  names and  addresses  appear in the  Security  Register.  Any
successor  Authenticating  Agent upon  acceptance of its  appointment  hereunder
shall become  vested with all the rights,  powers and duties of its  predecessor
hereunder,  with like effect as if originally named as an Authenticating  Agent.
No successor  Authenticating  Agent shall be appointed unless eligible under the
provisions of this Section 6.14.

     The Company  agrees to pay to each  Authenticating  Agent from time to time
reasonable compensation for its services under this Section 6.14.

                                       47


     If an appointment is made pursuant to this Section 6.14, the Securities may
have   endorsed   thereon,   in  addition  to  the  Trustee's   certificate   of
authentication,  an alternate  certificate  of  authentication  in the following
form:

     "This is one of the Securities of the series designated therein referred to
in the within-mentioned Indenture.

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

     Notwithstanding  any provision of this Section 6.14 to the contrary,  if at
any time any Authenticating Agent appointed hereunder with respect to any series
of Securities shall not also be acting as the Security Registrar  hereunder with
respect to any series of Securities, then, in addition to all other duties of an
Authenticating  Agent  hereunder,   such  Authenticating  Agent  shall  also  be
obligated:  (i) to furnish to the Security  Registrar  promptly all  information
necessary to enable the Security  Registrar to maintain at all times an accurate
and current Security  Register;  and (ii) prior to  authenticating  any Security
denominated  in a foreign  currency,  to ascertain from the Company the units of
such foreign currency that are required to be determined by the Company pursuant
to Section 3.02.

interest  so becoming  due,  such sum to be held in trust for the benefit of the
Persons entitled to such principal, premium or interest, and (unless such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of its action
or failure so to act.

     The Company will cause each Paying Agent for any series of Securities other
than the Trustee to execute and  deliver to the Trustee an  instrument  in which
such Paying Agent shall agree with the  Trustee,  subject to the  provisions  of
this Section 10.03, that such Paying Agent will:

     (1) hold all sums held by it for the payment of the principal  of,  premium
(if any) or interest on or any Additional  Amounts with respect to Securities of
that series in trust for the benefit of the Persons  entitled thereto until such
sums shall be paid to such Persons or otherwise disposed of as herein provided;

     (2) give the  Trustee  notice of any  default by the  Company (or any other
obligor  upon the  Securities  of that  series) in the making of any  payment of
principal  of,  premium (if any) or interest on or any  Additional  Amounts with


                                       55


respect to the Securities of that series; and

     (3) at any  time  during  the  continuance  of any such  default,  upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held in
trust by such Paying Agent.

     The Company may at any time, for the purpose of obtaining the  satisfaction
and  discharge of this  Indenture or for any other  purpose,  pay, or by Company
Order  direct any Paying  Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying  Agent,  such sums to be held by the Trustee upon the
same  trusts as those upon which  sums were held by the  Company or such  Paying
Agent;  and,  upon such payment by any Paying Agent to the Trustee,  such Paying
Agent shall be released from all further liability with respect to such sums.

     Any money  deposited with the Trustee or any Paying Agent,  or then held by
the Company,  in trust for the payment of the principal of,  premium (if any) or
interest on or any Additional Amounts with respect to any Security of any series
and remaining  unclaimed for two years after such principal of, premium (if any)
or interest on or any  Additional  Amounts with respect to any  Securities  have
become due and payable shall, unless otherwise required by mandatory  provisions
of applicable  escheat,  or abandoned or unclaimed  property law, be paid to the
Company on Company Request, or (if then held by the Company) shall be discharged
from  such  trust;  and the  Holder of such  Security  shall  thereafter,  as an
unsecured  general creditor,  look only to the Company for payment thereof,  and
all  liability  of the Trustee or such Paying  Agent with  respect to such trust
money,  and all  liability of the Company as trustee  thereof,  shall  thereupon
cease;  provided,  however,  that the Trustee or such Paying Agent, before being
required to make any such repayment,  may at the expense of the Company cause to
be published once, in an Authorized  Newspaper in The Borough of Manhattan,  The
City of New York and in such other  Authorized  Newspapers  as the Trustee shall
deem  appropriate,  notice that such money remains  unclaimed and that,  after a
date  specified  herein,  which  shall not be less than 30 days from the date of
such  publication,  any  unclaimed  balance of such money then  remaining  will,
unless  otherwise  required by mandatory  provisions of applicable  escheat,  or
abandoned or unclaimed property law, be repaid to the Company.

Section 10.04.    Existence.
                  ----------

     Subject  to  Article  Eight,  the  Company  will do or cause to be done all
things  necessary  to preserve  and keep in full force and effect its  corporate
existence.

Section 10.05.    Statement by Officers as to Default.
                  ------------------------------------

     The Company will  deliver to the Trustee,  within 120 days after the end of
each  fiscal  year of the  Company  ending  after the date hereof so long as any
Security is  outstanding  hereunder,  an Officers'  Certificate,  complying with
Section  314(a)(4) of the Trust  Indenture  Act and stating that a review of the
activities  of the  Company  during  such  year and of  performance  under  this
Indenture has been made under the supervision of the signers thereof and whether


                                       56


or not to the best of their knowledge, based upon such review, the Company is in
default in the  performance,  observance or  fulfillment of any of its covenants
and other  obligations  under this  Indenture,  and if the  Company  shall be in
default,  specifying  each such default  known to them and the nature and status
thereof.  One  of the  officers  signing  the  Officers'  Certificate  delivered
pursuant to this Section  10.05 shall be the principal  executive,  financial or
accounting officer of the Company.

     For purposes of this Section  10.05,  such  compliance  shall be determined
without regard to any period of grace or  requirement  of notice  provided under
this Indenture.

Section 10.06.    Waiver of Certain Covenants.
                  ----------------------------

     The Company may omit in any particular instance to comply with any covenant
or  condition  set forth in Sections  10.01  through  10.05,  inclusive,  or any
covenant  added for the benefit of any series of Securities as  contemplated  by
Section 3.01 (unless otherwise  specified pursuant to Section 3.01) if before or
after the time for such compliance the Holders of a majority in principal amount
of the  Outstanding  Securities  of all series  entitled  to the benefit of such
covenant  or  condition  (acting as one class)  shall,  by Act of such  Holders,
either waive such compliance in such instance or generally waive compliance with
such  covenant or  condition,  but no such waiver shall extend to or affect such
covenant or condition except to the extent so expressly waived,  and, until such
waiver shall become effective,  the obligations of the Company and the duties of
the Trustee in respect of any such  covenant or  condition  shall remain in full
force and effect.

Section 10.07.    Additional Amounts.
                  -------------------

     If the  Securities  of a  series  expressly  provide  for  the  payment  of
Additional  Amounts,  the Company will pay to the Holder of any Security of such
series  Additional  Amounts as  expressly  provided  therein.  Whenever  in this
Indenture there is mentioned,  in any context,  the payment of the principal of,
or  premium  (if any) or  interest  on any  Security  of any  series  or the net
proceeds received from the sale or exchange of any Security of any series,  such
mention shall be deemed to include mention of the payment of Additional  Amounts
provided  for in this  Section  10.07  to the  extent  that,  in  such  context,
Additional  Amounts are, were or would be payable in respect thereof pursuant to
the  provisions  of this  Section  10.07 and  express  mention of the payment of
Additional  Amounts  (if  applicable)  in any  provisions  hereof  shall  not be
construed as excluding  Additional Amounts in those provisions hereof where such
express mention is not made.

     If the  Securities  of a  series  provide  for the  payment  of  Additional
Amounts,  at least 10 days prior to the first Interest Payment Date with respect
to that series of Securities  (or if the Securities of that series will not bear
interest  prior to Maturity,  the first day on which a payment of principal  and
any  premium  is made),  and at least 10 days  prior to each date of  payment of
principal  and any premium or interest if there has been any change with respect
to the  matters  set forth in the  below-mentioned  Officers'  Certificate,  the
Company shall furnish the Trustee and the  Company's  principal  Paying Agent or
Paying  Agents,  if  other  than  the  Trustee,  with an  Officers'  Certificate
instructing  the Trustee and such Paying  Agent or Paying  Agents  whether  such
payment of  principal of and any premium or interest on the  Securities  of that


                                       57


series  shall be made to Holders  of  Securities  of that  series who are United
States Aliens without  withholding  for or on account of any tax,  assessment or
other  governmental  charge  described in the Securities of that series.  If any
such  withholding  shall be  required,  then such  Officers'  Certificate  shall
specify by country the amount,  if any, required to be withheld on such payments
to such Holders of Securities  and the Company will pay to such Paying Agent the
Additional  Amounts  required by this Section  10.07.  The Company  covenants to
indemnify  the  Trustee  and any  Paying  Agent for,  and to hold them  harmless
against any loss, liability or expense reasonably incurred without negligence or
bad faith on their part arising out of or in  connection  with actions  taken or
omitted  by any of them  in  reliance  on any  Officers'  Certificate  furnished
pursuant to this Section 10.07.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

Section 11.01.    Applicability of Article.
                  -------------------------

     Securities of any series which are redeemable  before their Stated Maturity
shall be  redeemable  in  accordance  with their terms and (except as  otherwise
specified  as  contemplated  by Section  3.01 for  Securities  of any series) in
accordance with this Article Eleven.

Section 11.02.    Election to Redeem; Notice to Trustee.
                  --------------------------------------

     Unless  otherwise  provided  with respect to the  Securities of a series as
contemplated  by  Section  3.01,  the  election  of the  Company  to redeem  any
Securities shall be evidenced by a Board  Resolution.  In case of any redemption
at the  election of the Company of less than all the  Securities  of any series,
the Company shall,  at least 40 days prior to the  Redemption  Date fixed by the
Company (unless a shorter notice shall be  satisfactory to the Trustee),  notify
the Trustee of such Redemption Date and of the principal amount of Securities of
such series to be redeemed. In the case of any redemption of Securities prior to
the expiration of any  restriction on such  redemption  provided in the terms of
such  Securities or elsewhere in this  Indenture,  the Company shall furnish the
Trustee  with  an  Officers'   Certificate   evidencing   compliance  with  such
restriction.  Any  election to redeem  Securities  will be  revocable  until the
Company  gives a notice of  redemption  pursuant to Section  11.04 hereof to the
Holders of Securities to be redeemed.

Section 11.03.    Selection by Trustee of Securities to be Redeemed.
                  --------------------------------------------------

     If less than all the  Securities  of any  series  are to be  redeemed,  the
particular Securities to be redeemed shall be selected not less than 30 days nor
more  than  60 days  prior  to the  Redemption  Date by the  Trustee,  from  the
Outstanding  Securities of such series not previously called for redemption,  by
such method as the Trustee shall deem fair and  appropriate and that may provide
for the selection for  redemption of portions  (equal to the minimum  authorized
denomination for Securities of that series or any integral  multiple thereof) of


                                       58


the principal amount of Securities of such series of a denomination  larger than
the minimum  authorized  denomination  for  Securities  of that series or of the
principal amount of global Securities of such series.

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

     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  Securities  redeemed or to be redeemed only in part, to the portion
of the principal amount of such Securities which has been or is to be redeemed.

Section 11.04.    Notice of Redemption.
                  ---------------------

     Notice of redemption  shall be given in the manner provided in Section 1.07
to each Holder of  Securities  to be redeemed  not less than 30 nor more than 60
days prior to the Redemption Date.

     All notices of redemption shall state:

     (1) the Redemption Date,

     (2) the Redemption Price,

     (3) if less than all the  Outstanding  Securities  of any  series are to be
redeemed,  the  identification  (and,  in the case of  partial  redemption,  the
principal amounts) of the particular Securities to be redeemed,

     (4) that on the Redemption Date the Redemption Price (together with accrued
and unpaid interest and any Additional Amounts to the Redemption Date payable as
provided in Section  11.06  hereof)  will become due and payable  upon each such
Security, or the portion thereof, to be redeemed,

     (5) that unless the Company defaults in the payment of the Redemption Price
and any applicable  accrued  interest,  interest on each such  Security,  or the
portion thereof, to be redeemed will cease to accrue on and after the Redemption
Date,

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

     (7) that the redemption is for a sinking fund, if such is the case, and

     (8) the "CUSIP" number, if applicable.

     A notice of  redemption as  contemplated  by Section 1.07 need not identify
particular  Securities to be redeemed.  Notice of redemption of Securities to be
redeemed at the election of the Company shall be given by the Company or, at the


                                       59


Company's request, by the Trustee in the name and at the expense of the Company.

Section 11.05.    Deposit of Redemption Price.
                  ----------------------------

     On or before 11:00 a.m.,  New York City time, on any  Redemption  Date, the
Company  shall  deposit  with the  Trustee or with a Paying  Agent  (or,  if the
Company  is  acting  as its own  Paying  Agent,  segregate  and hold in trust as
provided in Section  10.03) an amount of money  sufficient to pay the Redemption
Price of, and (except if the Redemption Date shall be an Interest  Payment Date)
accrued  interest  on,  and any  Additional  Amounts  with  respect  to, all the
Securities which are to be redeemed on that date.

Section 11.06.    Securities Payable on Redemption Date.
                  --------------------------------------

     Notice of redemption  having been given as aforesaid,  the Securities so to
be  redeemed  shall,  on the  Redemption  Date,  become  due and  payable at the
Redemption  Price  therein  specified,  and from and after such date (unless the
Company  shall  default  in the  payment  of the  Redemption  Price and  accrued
interest) such  Securities  shall cease to bear interest.  Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption  Price,  together with accrued interest
(and any Additional  Amounts) to the Redemption Date;  provided,  however,  that
installments  of interest whose Stated Maturity is on or prior to the Redemption
Date  shall  be  payable  to the  Holders  of  such  Securities,  or one or more
Predecessor  Securities,  registered  as such at the  close of  business  on the
relevant  Record Dates  according to their terms and the  provisions  of Section
3.07.

     If any Security  called for redemption  shall not be so paid upon surrender
thereof for redemption, the principal of and premium (if any) shall, until paid,
bear interest from the Redemption  Date at the rate  prescribed  therefor in the
Security or, in the case of Original Issue Discount Securities,  the Securities'
Yield to Maturity.

Section 11.07.    Securities Redeemed in Part.
                  ----------------------------

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

     Unless  otherwise  specified for a series of Securities as  contemplated by
Section  3.01,  the  Company  and any  Affiliate  of the Company may at any time
purchase  or  otherwise  acquire  Securities  in the open  market or by  private
agreement. Such acquisition shall not operate as or be deemed for any purpose to
be a  redemption  of  the  indebtedness  represented  by  such  Securities.  Any


                                       60


Securities  purchased or acquired by the Company may be delivered to the Trustee
and, upon such delivery, the indebtedness represented thereby shall be deemed to
be satisfied. Section 3.09 shall apply to all Securities so delivered.

                                 ARTICLE TWELVE

                                  SINKING FUNDS

Section 12.01.    Applicability of Article.
                  -------------------------

     The  provisions  of this Article  Twelve shall be applicable to any sinking
fund for the retirement of Securities of a series except as otherwise  specified
as contemplated by Section 3.01 for Securities of such series.

     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 Securities of any series is herein referred to as an "optional  sinking
fund  payment".  Unless  otherwise  provided by the terms of  Securities  of any
series,  the cash amount of any sinking fund payment may be subject to reduction
as provided in Section 12.02.  Each sinking fund payment shall be applied to the
redemption  of  Securities  of any  series  as  provided  for by  the  terms  of
Securities of such series.

Section 12.02.    Satisfaction of Sinking Fund Payments with Securities.
                  ------------------------------------------------------

     The Company (1) may deliver Outstanding  Securities of a series (other than
any previously  called for redemption) and (2) may apply as a credit  Securities
of a series  which have been  redeemed  either at the  election  of the  Company
pursuant to the terms of such Securities or through the application of permitted
optional sinking fund payments pursuant to the terms of such Securities, in each
case in satisfaction of all or any part of any sinking fund payment with respect
to the  Securities  of such series  required to be made pursuant to the terms of
such Securities as provided for by the terms of such series;  provided that such
Securities  have not been  previously  so  credited.  Such  Securities  shall be
received and credited  for such purpose by the Trustee at the  Redemption  Price
specified in such  Securities  for redemption  through  operation of the sinking
fund and the amount of such sinking payment shall be reduced accordingly.

Section 12.03.    Redemption of Securities for Sinking Fund.
                  ------------------------------------------

     Not less than 45 days prior (unless a shorter period shall be  satisfactory
to the Trustee) to each sinking fund payment date for any series of  Securities,
the Company will deliver to the Trustee an Officers' Certificate  specifying the
amount of the next ensuing  sinking fund payment for that series pursuant to the
terms of that series,  the portion thereof,  if any, which is to be satisfied by
payment of cash and the portion  thereof,  if any,  which is to be  satisfied by
delivery of or by crediting  Securities of that series pursuant to Section 12.02
and will also deliver to the Trustee any Securities to be so delivered. Not less
than 30 days before each such sinking fund payment date the Trustee shall select


                                       61


the  Securities to be redeemed upon such sinking fund payment date in the manner
specified  in Section  11.03 and cause  notice of the  redemption  thereof to be
given in the name of and at the expense of the Company in the manner provided in
Section  11.04.  Such  notice  having been duly given,  the  redemption  of such
Securities  shall be made upon the terms and in the  manner  stated in  Sections
11.06 and 11.07.

                                ARTICLE THIRTEEN

                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 13.01.    Company's Option to Effect Legal Defeasance or
                  ----------------------------------------------
 Covenant Defeasance.
- ---------------------

     The  Company may at its  option,  at any time elect to have either  Section
13.02 or Section 13.03 applied to the Outstanding  Securities of any series upon
compliance with the conditions set forth below in this Article Thirteen.

Section 13.02.    Legal Defeasance and Discharge.
                  -------------------------------

     Upon the  Company's  exercise  of the  option  provided  in  Section  13.01
applicable to this Section,  the Company shall be deemed to have been discharged
from its obligations with respect to the Outstanding Securities of any series on
the date the  conditions  set forth  below are  satisfied  (hereinafter,  "Legal
Defeasance").  For this purpose,  such legal  defeasance  means that the Company
shall be  deemed  (i) to have  paid and  discharged  its  obligations  under the
Outstanding Securities of such series; provided, however, that the Securities of
such series will  continue to be deemed  "Outstanding"  for  purposes of Section
13.05 and the other  Sections of this  Indenture  referred to in clauses (A) and
(B)  below,  and (ii) to have  satisfied  all its  other  obligations  under the
Securities of such series and this  Indenture  insofar as the Securities of such
series are  concerned  (and the Trustee,  at the expense of the  Company,  shall
execute proper  instruments  acknowledging the same),  except for the following,
which shall survive until otherwise terminated or discharged hereunder:  (A) the
rights of Holders of the  Securities of such series to receive,  solely from the
trust  fund  described  in  Section  13.04  and as more  fully set forth in such
Section, payments in respect of the principal of and any premium and interest on
the  Securities  of such series when such  payments are due,  (B) the  Company's
obligations  with respect to such Securities  under Sections 3.04,  3.05,  3.06,
10.02 and 10.03, (C) the rights,  powers,  trusts,  duties and immunities of the
Trustee hereunder and (D) this Article Thirteen. Subject to compliance with this
Article  Thirteen,  the Company may exercise its option under this Section 13.02
notwithstanding the prior exercise of its option under Section 13.03.

Section 13.03.    Covenant Defeasance.
                  --------------------

     Upon the  Company's  exercise  of the  option  provided  in  Section  13.01
applicable  to  this  Section,  (i) the  Company  shall  be  released  from  its
obligations  with respect to the  Securities  of such series under Section 8.01,
Section 10.06 and Section 10.07, and any covenants  provided pursuant to Section
3.01 for the  benefit of the Holders of such  Securities  (unless  otherwise  so
provided pursuant to Section 3.01), (ii) the occurrence of an event specified in


                                       62


Sections  5.01(3)  or (4) shall not be  deemed  to be an Event of  Default  with
respect to the  Securities  of such series on and after the date the  conditions
set forth  below are  satisfied,  and (iii) the  Securities  of such series will
thereafter be deemed not to be "Outstanding"  for the purposes of any direction,
waiver,  consent or declaration or Act of Holders (and the  consequences  of any
thereof)  in  connection  with such  covenants,  but will  continue to be deemed
"Outstanding"  for  all  other  purposes   hereunder   (hereinafter,   "Covenant
Defeasance").  For this  purpose,  such  Covenant  Defeasance  means that,  with
respect to the  Securities  of such series,  the Company may omit to comply with
and shall have no liability in respect of any term,  condition or limitation set
forth in any such Section or clause whether  directly or indirectly by reason of
any reference elsewhere herein to any such Section or clause or by reason of any
reference in any such Section or clause to any other provision  herein or in any
other document, but the remainder of this Indenture and such Securities shall be
unaffected thereby.

Section 13.04.    Conditions to Legal Defeasance or Covenant Defeasance.
                  ------------------------------------------------------

     The following  shall be the  conditions to  application  of either  Section
13.02 or Section 13.03 to the then Outstanding Securities of any series:

     (1) The Company shall  irrevocably have deposited or caused to be deposited
with the Trustee (or another trustee satisfying the requirements of Section 6.09
who  shall  agree  to  comply  with  the  provisions  of this  Article  Thirteen
applicable  to it) as  trust  funds in  trust  for the  purpose  of  making  the
following  payments  specifically  pledged as security for, and dedicated solely
to, the benefit of the Holders of the Securities of such series, (A) money in an
amount,  or (B) Government  Obligations  which through the scheduled  payment of
principal and interest in respect  thereof in  accordance  with their terms will
provide, not later than one day before the due date of any payment,  money in an
amount, or (C) a combination thereof, sufficient, in the opinion of a nationally
recognized  firm of independent  public  accountants or a nationally  recognized
investment banking firm expressed in a written  certification  thereof delivered
to  the  Trustee,   (if  such  firms  at  such  time  customarily  deliver  such
certifications,  and,  if not,  such  certification  may be from  the  principal
financial  officer of the  Company),  to pay and  discharge,  and which shall be
applied by the Trustee (or other qualifying  trustee) to pay and discharge,  the
principal  of,  premium,  if any,  and each  installment  of interest on and any
Additional  Amounts with respect to the  Securities of such series on the Stated
Maturity of such  principal or  installment  of interest in accordance  with the
terms of this Indenture and of the Securities of such series.

     (2) In the  event  of an  election  to  have  Section  13.02  apply  to any
Securities  or any series of  Securities,  as the case may be, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (x) the Company
has received from, or there has been published by, the Internal  Revenue Service
a ruling, or (y) since the date of this Indenture there has been a change in the
applicable  Federal income tax law, in either case to the effect that, and based
thereon  such  opinion  shall  confirm  that,  the  Holders  of the  Outstanding
Securities of such series will not recognize gain or loss for Federal income tax
purposes  as a result of such  deposit,  defeasance  and  discharge  and will be


                                       63


subject to Federal income tax on the same amount,  in the same manner and at the
same times as would have been the case if such deposit, defeasance and discharge
had not occurred;

     (3) In the  event  of an  election  to  have  Section  13.03  apply  to any
Securities  or any series of  Securities,  as the case may be, the Company shall
have  delivered  to the  Trustee an  Opinion  of Counsel to the effect  that the
Holders of the Outstanding  Securities of such series will not recognize gain or
loss for Federal  income tax  purposes as a result of such  deposit and covenant
defeasance and will be subject to Federal income tax on the same amount,  in the
same  manner and at the same  times as would have been the case if such  deposit
and covenant defeasance had not occurred;

     (4)  The  Company  shall  have   delivered  to  the  Trustee  an  Officers'
Certificate  and an Opinion of Counsel,  together  stating  that all  conditions
precedent  provided for relating to either the legal  defeasance  under  Section
13.02 or the covenant  defeasance  under Section 13.03 (as the case may be) have
been complied with;

     (5) Such legal  defeasance or covenant  defeasance  shall not result in the
trust arising from such deposit constituting an investment company as defined in
the Investment  Company Act, or such trust shall be qualified  under such act or
exempt from regulation thereunder;

     (6) At the time of such  deposit,  (A) no  default  in the  payment  of any
principal  of or  premium or  interest  on any  Senior  Indebtedness  shall have
occurred and be  continuing,  (B) no event of default with respect to any Senior
Indebtedness  shall have  resulted in such  Senior  Indebtedness  becoming,  and
continuing to be, due and payable prior to the date on which it would  otherwise
have become due and payable (unless payment of such Senior Indebtedness has been
made or duly  provided  for),  and (C) no other event of default with respect to
any Senior Indebtedness shall have occurred and be continuing  permitting (after
notice or lapse of time or both) the holders of such Senior  Indebtedness  (or a
trustee on behalf of such holders) to declare such Senior  Indebtedness  due and
payable  prior  to the date on which it  would  otherwise  have  become  due and
payable  or; in the case of  either  clause  (A),  (B) or (C)  above,  each such
default or event of default shall have been cured or waived or shall have ceased
to exist.

Section 13.05.    Deposited Money and Government Obligations to be Held in
                  --------------------------------------------------------
 Trust; Other Miscellaneous Provisions.
- ---------------------------------------

     Subject to the provisions of the last paragraph of Section 10.03, all money
and Government  Obligations  (including the proceeds thereof) deposited with the
Trustee (or other  qualifying  trustee  (solely for purposes of this Section and
Section  13.06,  the  Trustee  and  any  such  other  trustee  are  referred  to
collectively  as the  "Trustee")  pursuant  to  Section  13.04 in respect of the
Securities of such series shall be held in trust and applied by the Trustee,  in
accordance  with the  provisions  of such  Securities  of such  series  and this
Indenture,  to  the  payment,  either  directly  or  through  any  Paying  Agent
(including  the  Company  acting as its own  Paying  Agent) as the  Trustee  may
determine,  to the Holders of the Securities of such series, of all sums due and
to become due thereon in respect of principal (and premium, if any) and interest
and any  Additional  Amounts,  but such money need not be segregated  from other


                                       64


funds except to the extent  required by law. The Company shall pay and indemnify
the Trustee against any tax, fee or other charge imposed on or assessed  against
the Government  Obligations deposited pursuant to Section 13.04 or the principal
and interest  received in respect  thereof other than any such tax, fee or other
charge  which  by law is for  the  account  of the  Holders  of the  Outstanding
Securities.  Anything in this Article Thirteen to the contrary  notwithstanding,
the Trustee  shall  deliver or pay to the Company from time to time upon Company
Request any money or  Government  Obligations  held by it as provided in Section
13.04  which,  in the opinion of a  nationally  recognized  firm of  independent
public  accountants (or a nationally  recognized  investment banking firm or the
principal  financial  officer of the  Company,  as  appropriate)  expressed in a
written  certification  thereof  delivered to the Trustee,  are in excess of the
amount  thereof  which  would  then be  required  to be  deposited  to effect an
equivalent legal defeasance or covenant defeasance.

Section 13.06.    Reinstatement.
                  --------------

     If the  Trustee  or the  Paying  Agent  is  unable  to apply  any  money in
accordance with Section 13.02 or 13.03 by reason of any order or judgment of any
court or governmental authority enjoining,  restraining or otherwise prohibiting
such  application,  then the Company's  obligations under this Indenture and the
Securities  of such series shall be revived and  reinstated as though no deposit
had occurred pursuant to this Article Thirteen until such time as the Trustee or
Paying  Agent is permitted  to apply all such money in  accordance  with Section
13.02 or 13.03;  provided,  however,  that if the  Company  makes any payment of
principal  of (and  premium,  if any) or interest or  Additional  Amounts on any
Security  following the  reinstatement of its obligations,  the Company shall be
subrogated  to the rights of the  Holders of the  Securities  of such  series to
receive such payment from the money held by the Trustee or the Paying Agent.

Section 13.07.   Deposited Money and Government Obligations to be Held in Trust.
                 ---------------------------------------------------------------

     Subject to the provisions of the last paragraph of Section 10.03, all money
and Government  Obligations  (or other  property as may be provided  pursuant to
Section  3.01)  (including  the  proceeds  thereof)  deposited  with the Trustee
pursuant to Section  13.04 in respect of any  Securities  of any series shall be
held in trust and applied by the Trustee,  in accordance  with the provisions of
such Securities and this Indenture,  to the payment,  either directly or through
any Paying Agent  (including  the Company acting as its own Paying Agent) as the
Trustee may determine,  to the Holders of such Securities of all sums due and to
become due thereon in respect of principal,  premium,  if any, and interest,  if
any, and Additional  Amounts, if any, but such money need not be segregated from
other funds except as provided herein and except to the extent required by law.

                                ARTICLE FOURTEEN

                                  SUBORDINATION

Section 14.01.    Securities Subordinated to Senior Indebtedness.
                  -----------------------------------------------

     The Company and each Holder of a Security, by his acceptance thereof, agree
that (a) the payment of the principal  of,  premium (if any) and interest on and
any  Additional  Amounts with respect to each and all of the  Securities and (b)
any other  payment  in respect of the  Securities,  including  on account of the
acquisition or redemption of Securities by the Company, is subordinated,  to the
extent  and in the  manner  provided  in such  Security  or in the  supplemental
indenture  pursuant to which such  Security is issued,  to the prior  payment in
full  of  all  Senior  Indebtedness  specified  in  such  Security  or  in  such
supplemental indenture.

     Such  subordination  provisions  shall constitute a continuing offer to all
Persons who, in reliance upon such provisions, become holders of, or continue to
hold,  any of such Senior  Indebtedness,  and such  provisions  are made for the
benefit of the holders of such Senior  Indebtedness  and any one or more of them
may enforce such provisions.

Section 14.02.    Right of Trustee to Hold Senior Indebtedness.
                  ---------------------------------------------

     The  Trustee in its  individual  capacity  shall be  entitled to all of the
rights set forth in this Article Fourteen in respect of any Senior  Indebtedness
at any  time  held by it to the  same  extent  as any  other  holder  of  Senior
Indebtedness,  and nothing in this  Indenture  shall be construed to deprive the
Trustee 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 6.07.

Section 14.03.    Subordination Not to Prevent Events of Default.
                  -----------------------------------------------

     The failure to make a payment on account of principal of,  premium (if any)
or interest on the Securities by reason of any  subordination  provision for the
benefit of holders of Senior  Indebtedness  shall not be construed as preventing
the  occurrence of a Default or an Event of Default under Section 5.01 or in any
way prevent the Holders of the Securities  from  exercising any right  hereunder
other than the right to receive payment on the Securities.

Section 14.04.   No Fiduciary Duty of Trustee to Holders of Senior Indebtedness.
                 ---------------------------------------------------------------

     With respect to the holders of Senior Indebtedness,  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 such  Senior  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 Indebtedness, and shall not be liable to
any such holders  (other than for its willful  misconduct or  negligence)  if it
shall in good faith  mistakenly  pay over or  distribute  to the  Holders of the
Securities or the Company or any other Person,  cash,  property or securities to


                                       66


which any  holders of Senior  Indebtedness  shall be  entitled by virtue of this
Article  Fourteen or  otherwise.  Nothing in this Section 14.04 shall affect the
obligation of any other such Person to hold such payment for the benefit of, and
to pay such  payment  over to,  the  holders  of  Senior  Indebtedness  or their
representative.

Section 14.05.    Article Applicable to Paying Agent.
                  -----------------------------------

     In case at any time any Paying Agent other than the Trustee shall have been
appointed  by the Company and be then acting  hereunder,  the term  "Trustee" as
used in this  Article  Fourteen  shall in such case  (unless the  context  shall
otherwise  require) be construed as extending to and including such Paying Agent
within its meaning as fully for all intents and purposes as if such Paying Agent
were named in this  Article  Thirteen in addition to or in place of the Trustee;
provided, however, that this Section 14.05 shall not apply to the Company or any
Affiliate of the Company if it or such Affiliate acts as Paying Agent.

Section 14.06.    Defeasance of this Article Fourteen.
                  ------------------------------------

     The  subordination  of the Securities of a series  provided by this Article
Fourteen is expressly  made subject to the  provisions  for legal  defeasance or
covenant  defeasance  in Article  Thirteen  hereof and,  anything  herein to the
contrary notwithstanding, upon the effectiveness of any such legal defeasance or
covenant  defeasance,  the  Securities  of such  series then  outstanding  shall
thereupon cease to be subordinated pursuant to this Article Fourteen.
