the termination of holding the same, shall be proved by the Security Register.

         (4) The  ownership,  principal  amount  and  serial  numbers  of Bearer
Securities held by any Person,  and the date of the commencement and the date of
the  termination  of holding the same,  may be proved by the  production of such
Bearer  Securities or by a certificate  executed,  as


                                       13

depositary,  by any trust company,  bank, banker or other depositary  reasonably
acceptable  to the Company,  wherever  situated,  if such  certificate  shall be
deemed by the Company and the Trustee to be  satisfactory,  showing  that at the
date  therein  mentioned  such Person had on deposit  with such  depositary,  or
exhibited to it, the Bearer Securities therein  described;  or such facts may be
proved by the  certificate  or  affidavit  of the  Person  holding  such  Bearer
Securities,  if such  certificate  or  affidavit  is deemed by the Trustee to be
satisfactory.  The Trustee and the Company may assume that such ownership of any
Bearer Security  continues until (i) another  certificate or affidavit bearing a
later date issued in respect of the same Bearer  Security is  produced,  or (ii)
such Bearer  Security is produced to the Trustee by some other Person,  or (iii)
such Bearer  Security is surrendered in exchange for a Registered  Security,  or
(iv) such Bearer  Security is no longer  Outstanding.  The ownership,  principal
amount and serial numbers of Bearer  Securities  held by the Person so executing
such instrument or writing and the date of the  commencement and the date of the
termination of holding the same may also be proved in any other manner which the
Company and the Trustee deem sufficient.

         (5) If the Company  shall  solicit  from the Holders of any  Registered
Securities  any request,  demand,  authorization,  direction,  notice,  consent,
waiver or other Act, the Company may at its option (but is not obligated to), by
Board Resolution,  fix in advance a record date for the determination of Holders
of Registered Securities entitled to give such request,  demand,  authorization,
direction, notice, consent, waiver or other Act. If such a record date is fixed,
such request, demand, authorization, direction, notice, consent, waiver or other
Act may be given  before or after  such  record  date,  but only the  Holders of
Registered  Securities  of record at the close of  business  on such record date
shall be deemed to be Holders for the purpose of determining  whether Holders of
the requisite proportion of Outstanding  Securities have authorized or agreed or
consented to such request, demand,  authorization,  direction,  notice, consent,
waiver or other Act, and for that purpose the  Outstanding  Securities  shall be
computed as of such record date; provided that no such authorization,  agreement
or consent by the Holders of  Registered  Securities  shall be deemed  effective
unless it shall become  effective  pursuant to the  provisions of this Indenture
not later than six months after the record date.

         (6) Any request,  demand,  authorization,  direction,  notice, consent,
waiver or other Act by 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 or suffered to be done by the  Trustee,  any  Security
Registrar,  any Paying Agent or the Company in reliance thereon,  whether or not
notation of such Act is made upon such Security.

         Section 1.5.  Notices, Etc. to the Trustee and the Company.

         Any request, demand, authorization,  direction, notice, consent, waiver
or other  Act of  Holders  or  other  document  provided  or  permitted  by this
Indenture to be made upon, given or furnished to, or filed with,


                                       14
<PAGE>

         (1) the Trustee by any Holder or 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, or

         (2) the Company by the Trustee or any Holder  shall be  sufficient  for
every purpose  hereunder  (unless  otherwise  herein  expressly  provided) if in
writing and mailed, first-class postage prepaid, to the Company addressed to the
attention  of its Chief  Financial  Officer,  Controller  or  Secretary,  at the
address  of its  principal  office  specified  in the  first  paragraph  of this
instrument  or at any other  address  previously  furnished  in  writing  to the
Trustee by the Company.

         Section 1.6.  Notice to Holders of Securities; Waiver.

         Except  as  otherwise   expressly  provided  in  or  pursuant  to  this
Indenture,  where this Indenture provides for notice to Holders of Securities of
any event,

         (1) such notice shall be  sufficiently  given to Holders of  Registered
Securities if in writing and mailed, first-class postage prepaid, to each Holder
of a Registered Security affected by such event, at his address 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; and

         (2) such  notice  shall be  sufficiently  given to  Holders  of  Bearer
Securities,  if any, if published in an Authorized  Newspaper in The City of New
York and, if such  Securities are then listed on any stock exchange  outside the
United  States,  in an  Authorized  Newspaper in such city as the Company  shall
advise the Trustee that such stock  exchange so  requires,  on a Business Day at
least twice, the first such publication to be not earlier than the earliest date
and the second such  publication  not later than the latest date  prescribed for
the giving of such notice.

         In any case where notice to Holders of  Registered  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 Registered  Security shall affect the
sufficiency  of  such  notice  with  respect  to  other  Holders  of  Registered
Securities  or the  sufficiency  of any notice to  Holders of Bearer  Securities
given as  provided  herein.  Any  notice  which is mailed in the  manner  herein
provided shall be conclusively  presumed to have been duly given or provided. In
the 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 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 case by reason of the  suspension of  publication  of any Authorized
Newspaper or  Authorized  Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearers Securities as provided
above,  then such notification to Holders of Bearer Securities as shall be given
with the  approval of the Trustee  shall  constitute  sufficient  notice to such
Holders  for  every  purpose  hereunder.  Neither  failure  to  give  notice  by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published,


                                       15
<PAGE>

shall  affect  the  sufficiency  of any notice  mailed to Holders of  Registered
Securities as provided above.

         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  of  Securities  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 1.7.  Language of Notices.

         Any  request,  demand,   authorization,   direction,  notice,  consent,
election or waiver  required or permitted  under this Indenture  shall be in the
English  language,  except that, if the Company so elects,  any published notice
may be in an official language of the country of publication.

         Section 1.8.  Conflict with Trust Indenture Act.

         If any provision hereof limits,  qualifies or conflicts with any duties
under any  required  provision  of the Trust  Indenture  Act  imposed  hereon by
Section 318(c) thereof, such required provision shall control.

         Section 1.9.  Effect of Headings and Table of Contents.

         The Article and Section  headings  herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

         Section 1.10.  Successors and Assigns.

         All  covenants and  agreements  in this  Indenture by the Company shall
bind its successors and assigns, whether so expressed or not.

         Section 1.11.  Separability Clause.

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

         Section 1.12.  Benefits of Indenture.

         Nothing in this  Indenture,  any  Security  or any  Coupon,  express or
implied,  shall give to any Person,  other than the parties hereto, any Security
Registrar,  any Paying  Agent,  any  Authenticating  Agent and their  successors
hereunder and the Holders of Securities or Coupons,  any benefit or any legal or
equitable right, remedy or claim under this Indenture.

         Section 1.13.  Governing Law.

         This Indenture, the Securities and any Coupons shall be governed by and
construed in  accordance  with the laws of the State of New York  applicable  to
agreements made or instruments entered into and, in each case, performed in said
state.

         Section 1.14.  Legal Holidays.

         Unless  otherwise  specified  in or pursuant to this  Indenture  or any
Securities,  in any case where any Interest  Payment  Date,  Stated  Maturity or
Maturity  of any  Security,  or the last date on which a Holder has the right to
convert or exchange Securities of a series that are convertible or exchangeable,
shall be a Legal  Holiday at any Place of  Payment,  then  (notwithstanding  any
other  provision  of this  Indenture,  any  Security or any Coupon  other than a
provision in any Security or Coupon that specifically states that such provision
shall apply in lieu hereof) payment need not be made at such Place of Payment on
such date, and such  Securities  need not be converted or exchanged on such date
but such payment may be made, and such Securities may be converted or exchanged,
on the next  succeeding day that is a Business Day at such Place of Payment with
the same  force and  effect as if made on the  Interest  Payment  Date or at the
Stated Maturity or Maturity or on such last day for conversion or exchange,  and
no interest  shall accrue on the amount payable on such date or at such time for
the period from and after such Interest Payment Date, Stated Maturity,  Maturity
or last  day for  conversion  or  exchange,  as the case  may be,  to such  next
succeeding Business Day.

         Section 1.15.  Counterparts.

         This Indenture may be executed in several  counterparts,  each of which
shall be an  original  and all of which  shall  constitute  but one and the same
instrument.

         Section 1.16.  Judgment Currency.

         The Company agrees, to the fullest extent that it may effectively do so
under  applicable law, that (a) if for the purpose of obtaining  judgment in any
court it is necessary to convert the sum due in respect of the  principal of, or
premium or interest,  if any, or  Additional  Amounts on 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 requisite  amount of the Required  Currency with the
Judgment Currency on the New York Banking Day preceding the day on which a final
unappealable  judgment is given and (b) its obligations  under this Indenture to
make payments in the Required  Currency (i) shall not be discharged or satisfied
by any tender,  or any recovery pursuant to any judgment (whether or not entered
in  accordance  with  clause  (a)),  in any  currency  other  than the  Required
Currency,  except to the extent that such tender or recovery shall result in the
actual  receipt,  by the  payee,  of the full  amount of the  Required  Currency
expressed to be payable in respect of such  payments,  (ii) shall be enforceable
as an alternative or additional cause of action for the purpose of recovering in
the Required  Currency the amount,  if any, by which such actual  receipt  shall
fall  short of the


                                       17
<PAGE>

full amount of the Required  Currency so expressed to be payable and (iii) shall
not be  affected  by judgment  being  obtained  for any other sum due under this
Indenture.  For purposes of the foregoing,  "New York Banking Day" means any day
except a Saturday, Sunday or a legal holiday in The City of New York or a day on
which banking  institutions  in The City of New York are authorized or obligated
by law, regulation or executive order to be closed.

         Section 1.17.  No Security Interest Created.

         Subject to the provisions of Section 10.5, nothing in this Indenture or
in any Security, express or implied, shall be construed to constitute a security
interest under the Uniform  Commercial  Code or similar  legislation,  as now or
hereafter  enacted  and in  effect in any  jurisdiction  where  property  of the
Company or its Subsidiaries is or may be located.

         Section 1.18.  Limitation on Individual Liability.

         No  recourse  under  or upon  any  obligation,  covenant  or  agreement
contained in this  Indenture or in any Security,  or for any claim based thereon
or otherwise in respect thereof, shall be had against any incorporator,  officer
or director,  as such, past, present or future, of the Company,  either directly
or through the Company,  whether by virtue of any constitution,  statute or rule
of law, or by the  enforcement  of any  assessment or penalty or  otherwise;  it
being  expressly  understood  that this  Indenture  and the  obligations  issued
hereunder are solely corporate obligations,  and that no such personal liability
whatever  shall  attach to, or is or shall be  incurred  by, the  incorporators,
shareholders,  officers or directors,  as such, of the Company,  or any of them,
because of the creation of the indebtedness  hereby  authorized,  or under or by
reason of the obligations,  covenants or agreements  contained in this Indenture
or in any  Security  or implied  therefrom;  and that any and all such  personal
liability  of every  name and  nature,  either at common  law or in equity or by
constitution  or statute,  of, and any and all such  rights and claims  against,
every such incorporator,  shareholder,  officer or director, as such, because of
the creation of the indebtedness hereby authorized, or under or by reason of the
obligations,  covenants  or  agreements  contained  in this  Indenture or in any
Security or implied  therefrom,  are hereby  expressly  waived and released as a
condition of, and as a  consideration  for, the execution of this  Indenture and
the issuance of such Security.

         Each  Registered  Security,  Bearer  Security,  Coupon and temporary or
permanent global Security issued pursuant to this Indenture shall be in the form
established  by or pursuant to a Board  Resolution or in one or more  indentures
supplemental  hereto,  shall  have  such  appropriate   insertions,   omissions,

         Unless  otherwise  provided  in or pursuant  to this  Indenture  or any
Securities,  the Securities shall be issuable in registered form without Coupons
and shall not be issuable upon the exercise of warrants.

         Definitive   Securities  and  definitive   Coupons  shall  be  printed,
lithographed  or engraved or produced by any  combination  of these methods on a
steel engraved border or steel engraved  borders or may be produced in any other

represent the aggregate amount of all Outstanding  Securities of such series (or
such  lesser  amount as is  permitted  by the terms  thereof)  from time to time
endorsed  thereon and may also provide that the aggregate  amount of Outstanding
Securities  represented thereby may from time to time be increased or reduced to

Holders,  of Outstanding  Securities  represented  thereby shall be made in such
manner and by such  Person or Persons  as shall be  specified  therein or in the

expense,  any  Security  in  permanent  global  form  in  the  manner  and  upon

applicable  Company Order. If a Company Order pursuant to Section 3.3 or 3.4 has
been, or  simultaneously  is,


                                       19

delivered,  any instructions by the Company with respect to a Security in global
form shall be in  writing  but need not be  accompanied  by or  contained  in an

specified in or pursuant to this Indenture or any Security, payment of principal
of, any premium and interest on, and any  Additional  Amounts in respect of, any

in registered  form, the Holder of such global  Security in registered  form, or
(ii) in the case of a global  Security  in bearer  form,  the  Person or Persons

declaration of acceleration of the Maturity  thereof  pursuant to Section 5.2 or
the method by which such portion is to be determined;

         (15) if other than  Dollars,  the Foreign  Currency in which payment of
the  principal  of, any premium or interest on or any  Additional  Amounts  with
respect to any of such Securities shall be payable;

         (16) if the principal of, any premium or interest on or any  Additional
Amounts  with  respect  to any of  such  Securities  are to be  payable,  at the
election of the  Company or a Holder  thereof or  otherwise,  in Dollars or in a
Foreign  Currency  other  than that in which  such  Securities  are stated to be
payable, the date or dates on which, the period or periods within which, and the
other terms and conditions  upon which,  such election may be made, and the time
and manner of  determining  the exchange rate between the Currency in which such
Securities are stated to be payable and the Currency in which such Securities or

         (17)  whether the amount of payments  of  principal  of, any premium or
interest on or any  Additional  Amounts with respect to such  Securities  may be
determined with reference to an index, formula or other method or methods (which
index, formula or method or methods may be based, without limitation,  on one or
more  Currencies,  commodities,  equity  securities,  equity  indices  or  other
indices),  and,  if so,  the terms and  conditions  upon which and the manner in
which such amounts shall be determined and paid or payable;

         (18) any deletions from, modifications of or additions to the Events of
Default or  covenants  of the Company  with  respect to any of such  Securities,
whether or not such  Events of  Default or  covenants  are  consistent  with the
Events of Default or covenants set forth herein;

         (19) whether either or both of Section 4.2(2) relating to defeasance or
Section 4.2(3)  relating to covenant  defeasance  shall not be applicable to the
Securities of such series,  or any  covenants in addition to those  specified in
Section 4.2(3)  relating to the Securities of such series which shall be subject
to covenant  defeasance,  and any deletions from, or  modifications or additions
to, the provisions of Article 4 in respect of the Securities of such series;

         (20)  whether  any of  such  Securities  are to be  issuable  upon  the
exercise of warrants,  and the time,  manner and place for such Securities to be
authenticated and delivered;

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

         (23) any other terms of such Securities and any other deletions from or
modifications or additions to this Indenture in respect of such Securities.

         All Securities of any one series and all Coupons, if any,  appertaining
to Bearer  Securities of such series shall be substantially  identical except as
to Currency of payments due  thereunder,  denomination  and the rate of interest
thereon,  or method of determining the rate of interest,  if any, Maturity,  and
the date from which  interest,  if any, shall accrue and except as may otherwise
be provided by the Company in or pursuant to the Board  Resolution and set forth
in the Officer's  Certificate  or in any  indenture or  indentures  supplemental
hereto  pertaining to such series of Securities.  The terms of the Securities of
any  series  may  provide,  without  limitation,  that the  Securities  shall be
authenticated  and delivered by the Trustee on original  issue from time to time
upon  written  order of  persons  designated  in the  Officer's  Certificate  or
supplemental  indenture  and that such  persons  are  authorized  to  determine,
consistent  with  such  Officer's  Certificate  or any  applicable  supplemental
indenture,  such terms and  conditions  of the  Securities of such series as are
specified  in  such  Officer's  Certificate  or  supplemental   indenture.   All
Securities  of any one  series  need not be issued at the same time and,  unless
otherwise so  provided,  a series may be


                                       23
<PAGE>

reopened for issuances of  additional  Securities of such series or to establish
additional terms of such series of Securities.

         If  any  of the  terms  of  the  Securities  of  any  series  shall  be
established  by action  taken by or  pursuant to a Board  Resolution,  the Board
Resolution  shall be delivered to the Trustee at or prior to the delivery of the
Officer's Certificate setting forth the terms of such series.

         Section 3.2.  Currency; Denominations.

         Unless  otherwise  provided  in or  pursuant  to  this  Indenture,  the
principal  of, any  premium  and  interest on and any  Additional  Amounts  with
respect to the Securities shall be payable in Dollars. Unless otherwise provided
in or pursuant to this Indenture,  Registered Securities  denominated in Dollars
shall be issuable in registered form without Coupons in  denominations of $1,000
and any integral  multiple  thereof,  and the Bearer  Securities  denominated in
Dollars  shall  be  issuable  in the  denomination  of  $5,000.  Securities  not
denominated  in  Dollars  shall  be  issuable  in  such   denominations  as  are
established with respect to such Securities in or pursuant to this Indenture.

         Section 3.3.  Execution, Authentication, Delivery and Dating.

         Securities  shall be executed on behalf of the Company by its  Chairman
of the Board, its President,  its Chief Financial  Officer,  its Controller or a
Vice President under its corporate seal, if any, reproduced thereon and attested
by its Secretary or one of its Assistant Secretaries.  Coupons shall be executed
on behalf of the Company by the President,  Chief Financial Officer,  Controller
or  Treasurer  of the Company.  The  signature  of any of these  officers on the
Securities or any Coupons appertaining thereto may be manual or facsimile.

         Securities and any Coupons  appertaining  thereto 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 and Coupons or did not hold such offices at the date
of original issuance of such Securities or Coupons.

         At any time and from time to time after the  execution  and delivery of
this Indenture,  the Company may deliver  Securities,  together with any Coupons
appertaining thereto, executed by the Company, to the Trustee for authentication
and,   provided  that  the  Board   Resolution  and  Officer's   Certificate  or
supplemental indenture or indentures with respect to such Securities referred to
in Section 3.1 and a Company Order for the  authentication  and delivery of such
Securities  have been delivered to the Trustee,  the Trustee in accordance  with
the Company Order and subject to the  provisions  hereof and of such  Securities
shall  authenticate  and  deliver  such  Securities.   In  authenticating   such
Securities,  and accepting the additional  responsibilities under this Indenture
in relation to such Securities and any Coupons appertaining thereto, the Trustee
shall be entitled to receive,  and (subject to Sections 315(a) through 315(d) of
the Trust Indenture Act) shall be fully protected in relying upon,

                  (1)      an Opinion of Counsel to the effect that:

                           (a) the form or forms  and  terms of such  Securities
                  and Coupons,  if any, have been established in conformity with
                  the provisions of this Indenture;

                           (b) all  conditions  precedent to the  authentication
                  and  delivery  of  such   Securities  and  Coupons,   if  any,
                  appertaining  thereto,  have been  complied with and that such
                  Securities   and  Coupons,   when   completed  by  appropriate
                  insertions,  executed under the Company's  corporate  seal, if
                  any, and attested by duly authorized  officers of the Company,
                  delivered  by duly  authorized  officers of the Company to the
                  Trustee for  authentication  pursuant to this  Indenture,  and
                  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 legally valid and
                  binding  obligations of the Company,  enforceable  against the
                  Company in accordance with their terms,  except as enforcement
                  thereof   may  be  subject   to  or  limited  by   bankruptcy,
                  insolvency,    reorganization,     moratorium,    arrangement,
                  fraudulent  conveyance,  fraudulent  transfer or other similar
                  laws relating to or affecting creditors' rights generally, and
                  subject to general principles of equity (regardless of whether
                  enforcement is sought in a proceeding in equity or at law) and
                  will  entitle  the  Holders  thereof to the  benefits  of this
                  Indenture;  such Opinion of Counsel need express no opinion as
                  to the availability of equitable  remedies and may assume that
                  the  laws  of the  State  of New  York  are  identical  in all
                  relevant  aspects  to the  substantive  laws of the  State  of
                  Wisconsin;

                           (c) all  laws  and  requirements  in  respect  of the
                  execution and delivery by the Company of such  Securities  and
                  Coupons,  if any,  have  been  complied  with in all  material
                  respects; and

                           (d) this Indenture has been qualified under the Trust
                  Indenture Act; and

                  (2)  an  Officer's  Certificate  stating  that,  to  the  best
         knowledge of the Persons  executing  such  certificate,  all conditions
         precedent  to  the  execution,  authentication  and  delivery  of  such
         Securities  and  Coupons,  if  any,  appertaining  thereto,  have  been
         complied  with, and no event which is, or after notice or lapse of time
         would become, an Event of Default with respect to any of the Securities
         shall have occurred and be continuing.

         If all the  Securities  of any series are not to be issued at one time,
it shall not be  necessary  to deliver an  Opinion of Counsel  and an  Officer's
Certificate  at the time of  issuance  of each  Security,  but such  opinion and
certificate, with appropriate modifications, shall be delivered at or before the
time of issuance  of the first  Security  of such  series.  After any such first
delivery,  any separate written request by an Authorized  Officer of the Company
or any person  designated in writing by an  Authorized  Officer that the Trustee
authenticate  and deliver  Securities of such series for original  issue will be
deemed  to be a  certification  by the  Company  that all  conditions


                                       25
<PAGE>

precedent provided for in this Indenture relating to authentication and delivery
of such  Securities  continue  to have been  complied  with and that no Event of
Default with respect to any of the Securities has occurred or is continuing.

         The  Trustee  shall  not be  required  to  authenticate  or to cause an
Authenticating  Agent  to  authenticate  any  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  which is not  reasonably  acceptable  to the Trustee or if the  Trustee,
being advised by counsel, determines that such action may not lawfully be taken.

         Each Registered Security shall be dated the date of its authentication.
Each Bearer Security and any Bearer Security in global form shall be dated as of
the date specified in or pursuant to this Indenture.

         No Security  or Coupon  appertaining  thereto  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 in Section  2.2 or 6.12  executed by or on behalf of the
Trustee or by the  Authenticating  Agent by the manual  signature  of one of its
authorized  officers.  Such  certificate  upon any Security  shall be conclusive
evidence, and the only evidence,  that such Security has been duly authenticated
and delivered hereunder.  Except as permitted by Section 3.6 or 3.7, the Trustee
shall not  authenticate  and  deliver  any Bearer  Security  unless all  Coupons
appertaining thereto then matured have been detached and cancelled.

         Section 3.4.  Temporary Securities.

         Pending  the  preparation  of  definitive  Securities,  the Company may
execute and deliver to the Trustee and,  upon Company  Order,  the Trustee shall
authenticate  and  deliver,  in the manner  provided in Section  3.3,  temporary
Securities  in  lieu  thereof  which  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 or,  if  authorized  in or  pursuant  to this
Indenture,  in bearer form with one or more Coupons or without  Coupons and with
such appropriate  insertions,  omissions,  substitutions and other variations as
the  officers  of the  Company  executing  such  Securities  may  determine,  as
conclusively  evidenced by their  execution of such  Securities.  Such temporary
Securities may be in global form.

         Except in the case of temporary  Securities in global form, which shall
be exchanged in accordance with the provisions thereof, if temporary  Securities
are issued, the Company shall cause definitive Securities to be prepared without
unreasonable  delay. After the preparation of definitive  Securities of the same
series and containing  terms and  provisions  that are identical to those of any
temporary  Securities,  such temporary Securities shall be exchangeable for such
definitive  Securities upon surrender of such temporary  Securities at an Office
or Agency  for such  Securities,  without  charge to any  Holder  thereof.  Upon
surrender for cancellation of any one or more temporary Securities  (accompanied
by any unmatured Coupons  appertaining  thereto),  the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive  Securities of authorized  denominations of the same series
and


                                       26
<PAGE>

containing identical terms and provisions; provided, however, that no definitive
Bearer Security,  except as provided in or pursuant to this Indenture,  shall be
delivered  in  exchange  for a  temporary  Registered  Security;  and  provided,
further,  that a definitive Bearer Security shall be delivered in exchange for a
temporary Bearer Security only in compliance with the conditions set forth in or
pursuant to this  Indenture.  Unless  otherwise  provided in or pursuant to this
Indenture with respect to a temporary  global  Security,  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.

         Section 3.5.  Registration, Transfer and Exchange.

         With respect to the Registered  Securities of each series,  if any, the
Company  shall  cause to be kept a register  (each such  register  being  herein
sometimes  referred to as the  "Security  Register")  at an Office or Agency for
such  series  in  which,  subject  to  such  reasonable  regulations  as it  may
prescribe,  the Company shall  provide for the  registration  of the  Registered
Securities of such series and of transfers of the Registered  Securities of such
series. Such Office or Agency shall be the "Security  Registrar" for that series
of Securities.  Unless  otherwise  specified in or pursuant to this Indenture or
the  Securities,  the Trustee shall be the initial  Security  Registrar for each
series of  Securities.  The  Company  shall have the right to remove and replace
from time to time the Security Registrar for any series of Securities;  provided
that no such  removal  or  replacement  shall  be  effective  until a  successor
Security  Registrar  with respect to such series of  Securities  shall have been
appointed  by the  Company  and shall  have  accepted  such  appointment  by the
Company.  In the  event  that the  Trustee  shall  not be or  shall  cease to be
Security  Registrar  with respect to a series of  Securities,  it shall have the
right to examine the Security  Register for such series at all reasonable times.
There shall be only one Security Register for each series of Securities.

         Upon surrender for registration of transfer of any Registered  Security
of any  series at any  Office or  Agency  for such  series,  the  Company  shall
execute,  and the Trustee  shall  authenticate  and deliver,  in the name of the
designated  transferee or transferees,  one or more new Registered Securities of
the same series denominated as authorized in or pursuant to this Indenture, of a
like  aggregate   principal  amount  bearing  a  number  not   contemporaneously
outstanding and containing identical terms and provisions.

         At the option of the Holder, Registered Securities of any series may be
exchanged  for  other  Registered  Securities  of  the  same  series  containing
identical terms and provisions, in any authorized  denominations,  and of a like
aggregate  principal amount, upon surrender of the Securities to be exchanged at
any Office or Agency for such series.  Whenever any Registered Securities are so
surrendered  for  exchange,  the Company  shall  execute,  and the Trustee shall
authenticate and deliver, the Registered  Securities which the Holder making the
exchange is entitled to receive.

         If  provided  in  or  pursuant  to  this  Indenture,  with  respect  to
Securities of any series, at the option of the Holder, Bearer Securities of such
series may be exchanged  for  Registered  Securities  of such series  containing
identical terms,  denominated as authorized in or pursuant to


                                       27
<PAGE>

this Indenture and in the same aggregate principal amount, upon surrender of the
Bearer Securities to be exchanged at any Office or Agency for such series,  with
all unmatured  Coupons and all matured Coupons in default thereto  appertaining.
If the  Holder of a Bearer  Security  is unable to  produce  any such  unmatured
Coupon or Coupons or matured Coupon or Coupons in default,  such exchange may be
effected if the Bearer Securities are accompanied by payment in funds acceptable
to the  Company  and the  Trustee in an amount  equal to the face amount of such
missing  Coupon or Coupons,  or the surrender of such missing  Coupon or Coupons
may be waived by the Company and the Trustee if there is  furnished to them such
security  or  indemnity  as they may require to save each of them and any Paying
Agent harmless. If thereafter the Holder of such Bearer Security shall surrender
to any Paying Agent any such  missing  Coupon in respect of which such a payment
shall have been made,  such  Holder  shall be  entitled to receive the amount of
such payment;  provided,  however, that, except as otherwise provided in Section
10.2,  interest  represented by Coupons shall be payable only upon  presentation
and  surrender of those  Coupons at an Office or Agency for such series  located
outside  the United  States.  Notwithstanding  the  foregoing,  in case a Bearer
Security  of any  series is  surrendered  at any such  Office or Agency for such
series in exchange for a Registered Security of such series and like tenor after
the close of business  at such  Office or Agency on (i) any Regular  Record Date
and  before  the  opening  of  business  at such  Office  or  Agency on the next
succeeding Interest Payment Date, or (ii) any Special Record Date and before the
opening of business at such Office or Agency on the related  date for payment of
Defaulted Interest, such Bearer Security shall be surrendered without the Coupon
relating to such Interest Payment Date or proposed date of payment,  as the case
may be (or, if such Coupon is so  surrendered  with such Bearer  Security,  such
Coupon shall be returned to the Person so surrendering the Bearer Security), and
interest or Defaulted Interest, as the case may be, shall not be payable on such
Interest  Payment  Date or  proposed  date for  payment,  as the case may be, in
respect of the Registered  Security issued in exchange for such Bearer Security,
but shall be payable  only to the Holder of such Coupon  when due in  accordance
with the provisions of this Indenture.

         If provided in or pursuant to this Indenture with respect to Securities
of any series, at the option of the Holder, Registered Securities of such series
may be exchanged for Bearer  Securities upon such terms and conditions as may be
provided in or pursuant to this Indenture with respect to such series.

         Whenever any Securities are surrendered for exchange as contemplated by
the  immediately  preceding two paragraphs,  the Company shall execute,  and the
Trustee shall  authenticate and deliver,  the Securities which the Holder making
the exchange is entitled to receive.

         Notwithstanding  the  foregoing,  except as  otherwise  provided  in or
pursuant  to this  Indenture,  any global  Security  shall be  exchangeable  for
definitive  Securities  only if (i) the  Depository  is at any  time  unwilling,
unable or ineligible to continue as depository and a successor depository is not
appointed  by the Company  within 90 days of the date the Company is so informed
in writing,  (ii) the  Company  executes  and  delivers to the Trustee a Company
Order to the effect that such global Security shall be so exchangeable, or (iii)
an Event of Default has


                                       28
<PAGE>

occurred and is continuing  with respect to the  Securities.  If the  beneficial
owners of interests in a global Security are entitled to exchange such interests
for  definitive  Securities  as the result of an event  described in clause (i),
(ii) or (iii) of the preceding  sentence,  then without unnecessary delay but in
any event not later than the  earliest  date on which such  interests  may be so
exchanged,  the Company  shall deliver to the Trustee  definitive  Securities in
such form and  denominations  as are required by or pursuant to this  Indenture,
and of the same series,  containing  identical terms and in aggregate  principal
amount equal to the principal  amount of such global  Security,  executed by the
Company.  On or after  the  earliest  date on  which  such  interests  may be so
exchanged,  such global  Security shall be surrendered  from time to time by the
U.S.  Depository  or such other  Depository as shall be specified in the Company
Order with respect  thereto,  and in accordance with  instructions  given to the
Trustee and the U.S.  Depository  or such other  Depository,  as the case may be
(which  instructions  shall  be in  writing  but  need  not be  contained  in or
accompanied  by an  Officer's  Certificate  or be  accompanied  by an Opinion of
Counsel), as shall be specified in the Company Order with respect thereto to the
Trustee, as the Company's agent for such purpose,  to be exchanged,  in whole or
in part,  for  definitive  Securities  as described  above without  charge.  The
Trustee shall authenticate and make available for delivery, in exchange for each
portion of such surrendered global Security,  a like aggregate  principal amount
of definitive  Securities of the same series of authorized  denominations and of
like tenor as the portion of such global Security to be exchanged, which (unless
such  Securities  are not issuable both as Bearer  Securities  and as Registered
Securities,  in which case the  definitive  Securities  exchanged for the global
Security  shall  be  issuable  only in the  form in  which  the  Securities  are
issuable,  as provided in or pursuant to this Indenture) shall be in the form of
Bearer Securities or Registered Securities, or any combination thereof, as shall
be specified by the beneficial owner thereof, but subject to the satisfaction of
any  certification or other  requirements to the issuance of Bearer  Securities;
provided, however, that no such exchanges may occur during a period beginning at
the opening of business 15 days before any  selection of  Securities of the same
series to be redeemed and ending on the relevant  Redemption Date; and provided,
further,  that (unless  otherwise  provided in or pursuant to this Indenture) no
Bearer  Security  delivered in exchange for a portion of a global Security shall
be mailed or otherwise delivered to any location in the United States.  Promptly
following any such exchange in part,  such global  Security shall be returned by
the Trustee to such  Depository or the U.S.  Depository,  as the case may be, or
such other  Depository or U.S.  Depository  referred to above in accordance with
the instructions of the Company  referred to above. If a Registered  Security is
issued in  exchange  for any  portion  of a global  Security  after the close of
business at the Office or Agency for such Security where such exchange occurs on
or after (i) any Regular Record Date for such Security and before the opening of
business at such Office or Agency on the next succeeding  Interest Payment Date,
or (ii) any  Special  Record  Date for such  Security  and before the opening of
business at such Office or Agency on the  related  proposed  date for payment of
interest  or  Defaulted  Interest,  as the case may be,  interest  shall  not be
payable on such Interest Payment Date or proposed date for payment,  as the case
may be, in respect  of such  Registered  Security,  but shall be payable on such
Interest Payment Date or proposed date for payment,  as the case may be, only to
the Person to whom  interest in respect of such portion of such global  Security
shall be payable in accordance with the provisions of this Indenture.


                                       29
<PAGE>

         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 entitling the Holders thereof to the same benefits under this Indenture
as the Securities surrendered upon such registration of transfer or exchange.

         Every Registered  Security presented or surrendered for registration of
transfer or for exchange or  redemption  shall (if so required by the Company or
the Security Registrar for such Security) be duly endorsed, or be accompanied by
a written  instrument  of transfer in form  satisfactory  to the Company and the
Security  Registrar for such Security 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, or redemption of Securities,  but the Company may require payment of a
sum  sufficient  to cover  any tax or other  governmental  charge  and any other
expenses  (including  fees and expenses of the  Trustee)  that may be imposed in
connection with any  registration  of transfer or exchange of Securities,  other
than exchanges pursuant to Section 3.4, 9.5 or 11.7 not involving any transfer.

         Except as  otherwise  provided in or pursuant  to this  Indenture,  the
Company shall not be required (i) to issue, register the transfer of or exchange
any  Securities  during a period  beginning  at the  opening of business 15 days
before the day of mailing of a notice of  redemption of Securities of like tenor
and the same series  under  Section  11.3 and ending at the close of business on
the day of such  mailing,  or (ii) to register  the  transfer of or exchange any
Registered  Security  selected for redemption in whole or in part, except in the
case of any  Security  to be redeemed  in part,  the  portion  thereof not to be
redeemed,  or (iii) to exchange  any Bearer  Security  selected  for  redemption
except,  to the extent provided with respect to such Bearer Security,  that such
Bearer Security may be exchanged for a Registered Security of like tenor and the
same  series,  provided  that  such  Registered  Security  shall be  immediately
surrendered for redemption with written  instruction for payment consistent with
the provisions of this  Indenture or (iv) to issue,  register the transfer of or
exchange any Security which, in accordance with its terms,  has been surrendered
for repayment at the option of the Holder,  except the portion,  if any, of such
Security not to be so repaid.

         Section 3.6.  Mutilated, Destroyed, Lost and Stolen Securities.

         If  any  mutilated  Security  or a  Security  with a  mutilated  Coupon
appertaining  to it is surrendered to the Trustee,  subject to the provisions of
this Section 3.6, the Company shall  execute and the Trustee shall  authenticate
and deliver in exchange  therefor a new  Security of the same series  containing
identical  terms  and  of  like  principal  amount  and  bearing  a  number  not
contemporaneously  outstanding,  with Coupons appertaining thereto corresponding
to the Coupons, if any, appertaining to the surrendered Security.

         If there be  delivered  to the Company and the Trustee (i)  evidence to
their satisfaction of the destruction,  loss or theft of any Security or Coupon,
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 or Coupon has been


                                       30
<PAGE>

acquired by a bona fide  purchaser,  the Company  shall  execute  and,  upon the
Company's request the Trustee shall authenticate and deliver, in exchange for or
in lieu of any such mutilated, destroyed, lost or stolen Security or in exchange
for the Security to which a destroyed, lost or stolen Coupon appertains with all
appurtenant  Coupons not destroyed,  lost or stolen,  a new Security of the same
series  containing  identical  terms and of like principal  amount and bearing a
number not  contemporaneously  outstanding,  with Coupons  appertaining  thereto
corresponding to the Coupons,  if any,  appertaining to such destroyed,  lost or
stolen  Security  or to the  Security  to which such  destroyed,  lost or stolen
Coupon appertains.

         Notwithstanding  the foregoing  provisions of this Section 3.6, in case
any  mutilated,  destroyed,  lost or stolen  Security or Coupon 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 or Coupon;  provided,  however,  that
payment of principal  of, any premium or interest on or any  Additional  Amounts
with respect to any Bearer  Securities  shall,  except as otherwise  provided in
Section 10.2, be payable only at an Office or Agency for such Securities located
outside the United States and, unless otherwise  provided in or pursuant to this
Indenture,  any interest on Bearer  Securities and any  Additional  Amounts with
respect to such interest shall be payable only upon  presentation  and surrender
of the Coupons appertaining thereto.

         Upon the  issuance of any new  Security  under this  Section  3.6,  the
Company may require  the payment of a sum  sufficient  to cover any tax or other
governmental  charge  that may be  imposed  in  relation  thereto  and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

         Every  new  Security,  with any  Coupons  appertaining  thereto  issued
pursuant to this Section 3.6 in lieu of any destroyed,  lost or stolen Security,
or in  exchange  for a  Security  to which a  destroyed,  lost or stolen  Coupon
appertains shall constitute a separate obligation of the Company, whether or not
the destroyed,  lost or stolen Security and Coupons  appertaining thereto or the
destroyed, lost or stolen Coupon shall be at any time enforceable by anyone, and
shall  be  entitled  to  all  the  benefits  of  this   Indenture   equally  and
proportionately  with  any and all  other  Securities  of  such  series  and any
Coupons, if any, duly issued hereunder.

         The provisions of this Section 3.6, as amended or supplemented pursuant
to this Indenture with respect to particular  Securities or generally,  shall be
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 or Coupons.

         Section 3.7. Payment of Interest and Certain Additional Amounts; Rights
to Interest and Certain Additional Amounts Preserved.

         Unless  otherwise  provided  in or  pursuant  to  this  Indenture,  any
interest on and any Additional  Amounts with respect to any Registered  Security
which shall be payable,  and are  punctually  paid or duly  provided for, on any
Interest  Payment  Date shall be paid to the Person in whose name such  Security
(or one or  more  Predecessor  Securities)  is  registered  as of the  close  of
business on the Regular Record Date for such interest.


                                       31
<PAGE>

         Unless  otherwise  provided  in or  pursuant  to  this  Indenture,  any
interest on and any Additional  Amounts with respect to any Registered  Security
which shall be payable,  but shall not be punctually  paid or duly provided for,
on any  Interest  Payment  Date  for such  Registered  Security  (herein  called
"Defaulted  Interest") shall forthwith cease to be payable to the Holder thereof
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, as provided
in Clause (1) or (2) below:

                  (1) The  Company  may elect to make  payment of any  Defaulted
         Interest  to the Person in whose name such  Registered  Security  (or a
         Predecessor  Security  thereof)  shall be  registered  at the  close of
         business on a Special  Record  Date for the  payment of such  Defaulted
         Interest,  which shall be fixed by the Company in the following manner.
         The  Company  shall  notify  the  Trustee  in  writing of the amount of
         Defaulted Interest proposed to be paid on such Registered Security, the
         Special Record Date therefor 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 on or prior to the date of the  proposed
         payment,  such  money  when so  deposited  to be held in trust  for the
         benefit of the Person  entitled to such Defaulted  Interest as provided
         in this  clause (1).  The  Special  Record Date for the payment of such
         Defaulted  Interest 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  notification  to the Trustee of the proposed  payment.  The
         Trustee  shall,  in the name and at the expense of the  Company,  cause
         notice of the  proposed  payment  of such  Defaulted  Interest  and the
         Special Record Date therefor to be mailed, first-class postage prepaid,
         to the Holder of such  Registered  Security (or a Predecessor  Security
         thereof) at his address as it appears in the Security Register not less
         than 10 days prior to such Special Record Date. The Trustee may, in its
         discretion,  in the name and at the  expense  of the  Company,  cause a
         similar notice to be published at least once in an Authorized Newspaper
         of general  circulation  in the Borough of  Manhattan,  The City of New
         York, but such  publication  shall not be a condition  precedent to the
         establishment  of such  Special  Record  Date.  Notice of the  proposed
         payment of such Defaulted Interest and the Special Record Date therefor
         having been mailed as aforesaid,  such Defaulted Interest shall be paid
         to the Person in whose name such Registered  Security (or a Predecessor
         Security  thereof) shall be 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 in
         any other lawful manner not  inconsistent  with the requirements of any
         securities exchange on which such Security 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 payment shall be deemed practicable by the Trustee.

         Unless  otherwise  provided  in or pursuant  to this  Indenture  or the
Securities  of  any  particular  series  pursuant  to  the  provisions  of  this
Indenture, at the option of the Company,  interest on Registered Securities that
bear  interest  may be paid by  mailing  a check to the  address  of the  Person
entitled  thereto as such address  shall  appear in the Security  Register or by
transfer to an account maintained by the payee with a bank located in the United
States.

         Subject to the  foregoing  provisions  of this Section and Section 3.5,
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.

         In  the  case  of  any  Registered  Security  of  any  series  that  is
convertible  into other securities of the Company or exchangeable for securities
of another issuer, which Registered Security is converted or exchanged after any
Regular Record Date and on or prior to the next succeeding Interest Payment Date
(other than any Registered Security with respect to which the Stated Maturity is
prior to such Interest Payment Date),  interest with respect to which the Stated
Maturity  is on such  Interest  Payment  Date shall be payable on such  Interest
Payment Date  notwithstanding  such  conversion  or exchange,  and such interest
(whether  or not  punctually  paid or duly  provided  for)  shall be paid to the
Person  in whose  name  that  Registered  Security  (or one or more  predecessor
Registered  Securities)  is  registered at the close of business on such Regular
Record Date. Except as otherwise expressly provided in the immediately preceding
sentence,  in  the  case  of any  Registered  Security  which  is  converted  or
exchanged,  interest with respect to which the Stated Maturity is after the date
of conversion or exchange of such Registered Security shall not be payable.

         Section 3.8.  Persons Deemed Owners.

         Prior to due presentment of a Registered  Security for  registration of
transfer,  the Company,  the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Registered Security is registered in the
Security  Register as the owner of such  Registered  Security for the purpose of
receiving  payment of principal of, any premium and (subject to Sections 3.5 and
3.7)  interest on and any  Additional  Amounts with  respect to such  Registered
Security and for all other purposes whatsoever,  whether or not any payment with
respect to such Registered  Security shall be overdue,  and none of the Company,
the  Trustee or any agent of the  Company or the  Trustee  shall be  affected by
notice to the contrary.

         The  Company,  the  Trustee and any agent of the Company or the Trustee
may treat the bearer of any Bearer  Security  or the bearer of any Coupon as the
absolute  owner of such Security or Coupon for the purpose of receiving  payment
thereof or on account thereof and for all other purposes whatsoever,  whether or
not any payment  with respect to such  Security or Coupon shall be overdue,  and
none of the  Company,  the  Trustee or any agent of the  Company or the  Trustee
shall be affected by notice to the contrary.

         No Holder of any beneficial interest in any global Security held on its
behalf by a Depository  shall have any rights under this  Indenture with respect
to such global Security, and


                                       33
<PAGE>

such Depository may be treated by the Company,  the Trustee and any agent of the
Company or the Trustee as the owner of such  global  Security  for all  purposes
whatsoever.  None of the Company,  the Trustee, any Paying Agent or the Security
Registrar  will  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 or for maintaining,  supervising or reviewing any
records relating to such beneficial ownership interests.

         Section 3.9.  Cancellation.

         All  Securities  and  Coupons  surrendered  for  payment,   redemption,
registration  of  transfer,  exchange or  conversion  or for credit  against any
sinking fund payment shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee,  and any such  Securities  and Coupons,  as well as
Securities and Coupons surrendered directly to the Trustee for any such purpose,
shall be cancelled promptly 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 cancelled  promptly by the
Trustee.  No Securities shall be authenticated in lieu of or in exchange for any
Securities cancelled as provided in this section,  except as expressly permitted
by or pursuant to this Indenture.  All cancelled  Securities and Coupons held by
the Trustee  shall be destroyed by the  Trustee,  unless by a Company  Order the
Company directs their return to it.

         Section 3.10.  Computation of Interest.

         Except as otherwise provided in or pursuant to this Indenture or in any
Security, interest on the Securities shall be computed on the basis of a 360-day
year of twelve 30-day months.

         Section 4.1.  Satisfaction and Discharge.

         Upon the direction of the Company by a Company  Order,  this  Indenture
shall  cease to be of further  effect with  respect to any series of  Securities
specified in such Company Order and any Coupons  appertaining  thereto,  and the
Trustee,  on receipt of a Company  Order,  at the expense of the Company,  shall
execute  proper  instruments  acknowledging  satisfaction  and discharge of this
Indenture as to such series, when

                  (1)      either

                           (a)  all   Securities  of  such  series   theretofore
                  authenticated  and  delivered  and  all  Coupons  appertaining
                  thereto  (other  than  (i)  Coupons   appertaining  to  Bearer
                  Securities  of  such  series   surrendered   in  exchange  for
                  Registered  Securities of such series and maturing  after such
                  exchange whose surrender is not required

                  for whose  payment  money has  theretofore  been  deposited in
                  trust or  segregated  and held in  trust  by the  Company  and

                  (i) or  (ii)  below,  any  Coupons  appertaining  thereto  not
                  theretofore  delivered  to the Trustee for  cancellation,  (i)
                  have  become  due and  payable,  or (ii) will  become  due and
                  payable at their Stated  Maturity within one year, or (iii) if
                  redeemable at the option of the Company,  are to be called for
                  redemption within one year under arrangements  satisfactory to
                  the  Trustee  for the  giving of notice of  redemption  by the
                  Trustee in the name, and at the expense,  of the Company,  and
                  the  Company,  in the case of (i),  (ii) or (iii)  above,  has
                  deposited or caused to be deposited  with the Trustee as trust
                  funds in trust  for such  purpose,  money in the  Currency  in
                  which such  Securities are payable in an amount  sufficient to
                  pay and discharge the entire  indebtedness  on such Securities
                  and any Coupons appertaining thereto not theretofore delivered
                  to the Trustee for  cancellation,  including the principal of,
                  any premium and interest on, and any  Additional  Amounts with
                  respect  to  such  Securities  and  any  Coupons  appertaining
                  thereto,  to  the  date  of  such  deposit  (in  the  case  of
                  Securities  which  have  become  due  and  payable)  or to the
                  Maturity thereof, as the case may be;

         payable  hereunder  by the  Company  with  respect  to the  Outstanding
         Securities of such series and any Coupons appertaining thereto; and

                  (3) the Company  has  delivered  to the  Trustee an  Officer's
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent   herein  provided  for  relating  to  the  satisfaction  and
         discharge of this Indenture as to such series have been complied with.

         In the event there are Securities of two or more series hereunder,  the
Trustee  shall be required to execute an instrument  acknowledging  satisfaction
and  discharge  of this  Indenture  only if  requested  to do so with respect to
Securities of such series as to which it is Trustee and if the other  conditions
thereto are met.

         Notwithstanding  the  satisfaction and discharge of this Indenture with
respect to any  series of  Securities,  the  obligations  of the  Company to the
Trustee  under  Section  6.7 and, if money  shall have been  deposited  with the
Trustee pursuant to subclause (b) of clause (1) of this section, the obligations
of the Company and the Trustee  with  respect to the  Securities  of such series

under  Sections 3.5,  3.6,  4.3,  10.2 and 10.3,  with respect to the payment of
Additional  Amounts,  if any, with respect to such Securities as contemplated by
Section 10.4 (but only to the extent that the  Additional  Amounts  payable with
respect  to such  Securities  exceed  the  amount  deposited  in respect of such
Additional  Amounts  pursuant  to Section  4.1(1)(b)),  and with  respect to any
rights to convert or exchange such  Securities into securities of the Company or
another issuer shall survive.

         Section 4.2.  Defeasance and Covenant Defeasance.

                  (1)  Unless  pursuant  to Section  3.1,  either or both of (i)
         defeasance of the  Securities of or within a series under clause (2) of
         this Section 4.2 shall not be applicable with respect to the Securities
         of such series or (ii)  covenant  defeasance  of the  Securities  of or
         within a series  under  Section  4.2(3)  shall not be  applicable  with
         respect  to the  Securities  of  such  series,  then  such  provisions,
         together  with the other  provisions  of this  Section  4.2 (with  such
         modifications  thereto as may be specified pursuant to Section 3.1 with
         respect to any Securities),  shall be applicable to such Securities and
         any Coupons appertaining  thereto, and the Company may at its option by
         Board Resolution,  at any time, with respect to such Securities and any
         Coupons appertaining  thereto,  elect to have Section 4.2(2) or Section
         4.2(3)  be  applied  to such  Outstanding  Securities  and any  Coupons
         appertaining  thereto upon  compliance  with the  conditions  set forth
         below in this Section 4.2.

                  (2) Upon the Company's exercise of the above option applicable
         to this Section  4.2(2) with respect to any  Securities  of or within a
         series,  the Company shall be deemed to have been  discharged  from its
         obligations with respect to such Outstanding Securities and any Coupons
         appertaining thereto on the date the conditions set forth in clause (4)
         of this Section 4.2 are satisfied (hereinafter, "defeasance"). For this
         purpose, such defeasance means that the Company shall be deemed to have
         paid  and  discharged  the  entire  Indebtedness  represented  by  such
         Outstanding  Securities  and any Coupons  appertaining  thereto,  which
         shall thereafter be deemed to be "Outstanding" only for the purposes of
         clause (5) of this Section 4.2 and the other Sections of this Indenture
         referred to in clauses (i) and (ii) below, and to have satisfied all of
         its  other   obligations   under  such   Securities   and  any  Coupons
         appertaining thereto, and this Indenture insofar as such Securities and
         any Coupons appertaining thereto 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:  (i) the rights of Holders of such
         Outstanding Securities and any Coupons appertaining thereto to receive,
         solely from the trust fund  described in clause (4) of this Section 4.2
         and as more fully set forth in such clause,  payments in respect of the
         principal  of (and  premium,  if any) and  interest,  if any,  on,  and
         Additional  Amounts,  if any, with respect to, such  Securities and any
         Coupons appertaining thereto when such payments are due, and any rights
         of such Holder to convert such Securities into other  securities of the
         Company or exchange such  Securities for securities of another  issuer,
         (ii) the  obligations  of the Company and the Trustee  with  respect to
         such Securities under Sections 3.5, 3.6,

         10.2 and 10.3 and with respect to the payment of Additional Amounts, if
         any, on such  Securities as  contemplated  by Section 10.4 (but only to
         the extent that the  Additional  Amounts  payable  with respect to such
         Securities  exceed the amount  deposited in respect of such  Additional
         Amounts pursuant to Section 4.2(4)(a)  below),  and with respect to any
         rights to convert such Securities into other  securities of the Company
         or exchange such Securities for securities of another issuer, (iii) the
         rights,  powers, trusts, duties and immunities of the Trustee hereunder
         and (iv) this  Section  4.2.  The Company may exercise its option under
         this Section  4.2(2)  notwithstanding  the prior exercise of its option
         under clause (3) of this  Section 4.2 with  respect to such  Securities
         and any Coupons appertaining thereto.

                  (3) Upon the  Company's  exercise  of the  option to have this
         Section  4.2(3)  apply with  respect to any  Securities  of or within a
         series,  the  Company  shall be  released  from its  obligations  under
         Sections  10.5 and 10.6,  and,  to the  extent  specified  pursuant  to
         Section 3.1(19), any other covenant applicable to such Securities, with
         respect to such  Outstanding  Securities  and any Coupons  appertaining
         thereto,  on and after the date the  conditions set forth in clause (4)
         of this Section 4.2 are satisfied (hereinafter, "covenant defeasance"),
         and  such  Securities  and  any  Coupons   appertaining  thereto  shall
         thereafter  be deemed to be not  "Outstanding"  for the purposes of any
         direction,  waiver,  consent or  declaration or Act of Holders (and the
         consequences of any thereof) in connection with any such covenant,  but
         shall  continue  to be  deemed  "Outstanding"  for all  other  purposes
         hereunder.  For this purpose, such covenant defeasance means that, with
         respect to such  Outstanding  Securities  and any Coupons  appertaining
         thereto,  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  such  other  covenant,   whether   directly  or
         indirectly,  by reason of any  reference  elsewhere  herein to any such
         section or such other  covenant or by reason of  reference  in any such
         section or such other covenant to any other provision  herein or in any
         other  document  and such  omission to comply  shall not  constitute  a
         default  or an Event of  Default  under  Section  5.1(4)  or  5.1(8) or
         otherwise,  as the case may be, but,  except as  specified  above,  the
         remainder  of  this   Indenture   and  such   Securities   and  Coupons
         appertaining thereto shall be unaffected thereby.

                  (4) The following  shall be the  conditions to  application of
         clause (2) or (3) of this Section 4.2 to any Outstanding  Securities of
         or within a series and any Coupons appertaining thereto:

                           (a) The Company shall  irrevocably  have deposited or
                  caused to be  deposited  with the Trustee (or another  trustee
                  satisfying the  requirements of Section 6.8 who shall agree to
                  comply with the  provisions of this Section 4.2  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 such
                  Securities and any Coupons appertaining thereto, (1) an amount
                  in  Dollars  or  in  such  Foreign   Currency  in  which  such
                  Securities  and any  Coupons  appertaining  thereto  are  then
                  specified  as payable at Stated  Maturity,  or


                                       37

                  (2) Government  Obligations  applicable to such Securities and
                  Coupons  appertaining  thereto (determined on the basis of the
                  Currency in which such  Securities  and  Coupons  appertaining
                  thereto  are then  specified  as payable  at Stated  Maturity)
                  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 of principal of (and premium, if any) and interest, if
                  any, on such Securities and any Coupons appertaining  thereto,
                  money in an amount, or (3) a combination thereof, in any case,
                  in  an  amount,  sufficient,   without  consideration  of  any
                  reinvestment of such principal and interest, in the opinion of
                  a nationally recognized firm of independent public accountants
                  expressed in a written  certification thereof delivered to the
                  Trustee,  to pay and discharge,  and which shall be applied by
                  the  Trustee  (or  other   qualifying   trustee)  to  pay  and
                  discharge,  (y) the  principal  of (and  premium,  if any) and
                  interest,  if any,  on  such  Outstanding  Securities  and any
                  Coupons  appertaining  thereto at the Stated  Maturity of such
                  principal or  installment  of principal or premium or interest
                  and (z) any  mandatory  sinking  fund  payments  or  analogous
                  payments  applicable to such  Outstanding  Securities  and any
                  Coupons  appertaining  thereto  on  the  days  on  which  such
                  payments are due and payable in  accordance  with the terms of
                  this  Indenture  and  of  such   Securities  and  any  Coupons
                  appertaining thereto.

                           (b) Such defeasance or covenant  defeasance shall not
                  result in a breach or  violation  of, or  constitute a default
                  under,  this  Indenture  or any other  material  agreement  or
                  instrument  to which the  Company is a party or by which it is
                  bound.

                           (c) No Event of Default or event which with notice or
                  lapse of time or both would  become an Event of  Default  with
                  respect  to  such  Securities  and  any  Coupons  appertaining
                  thereto  shall have  occurred and be continuing on the date of
                  such deposit and, with respect to defeasance only, at any time
                  during  the  period  ending on the 123rd day after the date of
                  such deposit (it being  understood  that this condition  shall
                  not be deemed satisfied until the expiration of such period).

                           (d) In the case of an  election  under  clause (2) of
                  this  Section  4.2,  the Company  shall have  delivered to the
                  Trustee an Opinion of Counsel stating that (i) the Company has
                  received from the Internal Revenue Service a letter ruling, or
                  there has been  published  by the Internal  Revenue  Service a
                  Revenue  Ruling,  or (ii) since the date of  execution 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 such
                  Outstanding  Securities and any Coupons  appertaining  thereto
                  will not recognize income, gain or loss for Federal income tax
                  purposes as a result of such defeasance and will be subject to
                  Federal income tax on the same amounts, in the same manner and
                  at the  same  times  as  would  have  been  the  case  if such
                  defeasance had not occurred.

                           (e) In the case of an  election  under  clause (3) of
                  this  Section  4.2,  the Company  shall have  delivered to the
                  Trustee an Opinion of Counsel to the effect  that the  Holders
                  of such  Outstanding  Securities and any Coupons  appertaining
                  thereto will not  recognize  income,  gain or loss for Federal
                  income tax  purposes as a result of such  covenant  defeasance
                  and will be subject to Federal income tax on the same amounts,
                  in the same  manner  and at the same  times as would have been
                  the case if such covenant defeasance had not occurred.

                           (f) The Company  shall have  delivered to the Trustee
                  an Opinion of Counsel to the effect that,  after the 123rd day
                  after  the  date  of   deposit,   all  money  and   Government
                  Obligations (or other property as may be provided  pursuant to
                  Section 3.1)  (including  the proceeds  thereof)  deposited or
                  caused to be deposited  with the Trustee (or other  qualifying
                  trustee)  pursuant to this clause (4) to be held in trust will
                  not be subject to any case or proceeding (whether voluntary or
                  involuntary)  in respect of the  Company  under any Federal or
                  State bankruptcy, insolvency,  reorganization or other similar
                  law,  or any  decree or order for  relief  in  respect  of the
                  Company issued in connection therewith.

                           (g) The Company  shall have  delivered to the Trustee
                  an Officer's  Certificate and the Company shall have delivered
                  to the Trustee an Opinion of Counsel,  each  stating  that all
                  conditions  precedent to the defeasance or covenant defeasance
                  under  clause (2) or (3) of this  Section 4.2 (as the case may
                  be) have been complied with.

                           Notwithstanding  any other provisions of this Section
                  4.2(4),  such  defeasance  or  covenant  defeasance  shall  be
                  effected  in  compliance  with any  additional  or  substitute
                  terms,  conditions or limitations  which may be imposed on the
                  Company in connection therewith pursuant to Section 3.1.

                  (5)  Unless  otherwise   specified  in  or  pursuant  to  this
         Indenture or any Security,  if, after a deposit  referred to in Section
         4.2(4)(a)  has been made,  (a) the  Holder of a Security  in respect of
         which such deposit was made is entitled to, and does, elect pursuant to
         Section  3.1 or the terms of such  Security  to  receive  payment  in a
         Currency  other  than that in which the  deposit  pursuant  to  Section
         4.2(4)(a)  has  been  made  in  respect  of  such  Security,  or  (b) a
         Conversion Event occurs in respect of the Foreign Currency in which the
         deposit  pursuant to Section  4.2(4)(a) has been made, the indebtedness
         represented by such Security and any Coupons appertaining thereto shall
         be deemed to have been,  and will be, fully  discharged  and  satisfied
         through the payment of the  principal  of (and  premium,  if any),  and
         interest,  if any, on, and Additional Amounts, if any, with respect to,
         such  Security as the same becomes due out of the  proceeds  yielded by
         converting  (from  time to time as  specified  below in the case of any
         such  election)  the amount or other  property  deposited in respect of
         such Security into the Currency in which such Security  becomes payable
         as a result of such  election or  Conversion  Event based on (x) in the
         case of  payments  made  pursuant to clause (a) above,  the  applicable
         market


                                       39
<PAGE>

         exchange  rate for such  Currency in effect on the second  Business Day
         prior to each payment date, or (y) with respect to a Conversion  Event,
         the applicable market exchange rate for such Foreign Currency in effect
         (as nearly as feasible) at the time of the Conversion Event.

         The Company shall pay and  indemnify  the Trustee (or other  qualifying
trustee,  collectively  for purposes of this Section 4.2(5) and Section 4.3, the
"Trustee") against any tax, fee or other charge,  imposed on or assessed against
the  Government  Obligations  deposited  pursuant  to  this  Section  4.2 or the
principal or 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  such
Outstanding Securities and any Coupons appertaining thereto.

         Anything  in this  Section  4.2 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 (or other property and any proceeds
therefrom)  held by it as provided in clause (4) of this  Section 4.2 which,  in
the opinion of a nationally  recognized firm of independent  public  accountants
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 a defeasance or covenant  defeasance,  as applicable,  in accordance with
this Section 4.2.

         Section 4.3.  Application of Trust Money.

         Subject to the  provisions of the last  paragraph of Section 10.3,  all
money and Government  Obligations (or other property as may be provided pursuant
to Section 3.1)  (including  the proceeds  thereof)  deposited  with the Trustee
pursuant to Section 4.1 or 4.2 in respect of any  Outstanding  Securities of any
series and any Coupons  appertaining  thereto shall be held in trust and applied
by the Trustee,  in accordance  with the  provisions of such  Securities and any
Coupons appertaining thereto 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 and any
Coupons  appertaining  thereto  of all sums due and to  become  due  thereon  in
respect of principal (and premium,  if any) and interest and Additional Amounts,
if any; but such money and Government  Obligations  need not be segregated  from
other funds except to the extent required by law.

         any Designated Subsidiary (including, in each case, an Event of Default
         under any other series of Securities),  whether such  Indebtedness  now
         exists or shall  hereafter  be created or  incurred,  shall  happen and
         shall  consist,  in the  aggregate,  of the  default in the  payment of

         discharge such  Indebtedness  having been set aside by the Company,  in
         each case within a period of 30 days after there shall have been given,

         Company or any  substantial  part of the property of the Company or the
         making by the Company of an assignment for the benefit of creditors, or
         the taking of  corporate  action by the Company in  furtherance  of any
         such action; or

                  (8) any other Event of Default provided in or pursuant to this
         Indenture with respect to Securities of such series.

         Section 5.2.  Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default with respect to  Securities of any series at the
time Outstanding  (other than an Event of Default specified in clause (6) or (7)
of Section 5.1) occurs and is continuing, then the Trustee or the Holders of not
less than 25% in principal  amount of the Outstanding  Securities of such series
may declare the principal of all the  Securities of such series,  or such lesser
amount as may be provided for in the  Securities  of such series,  to be due and
payable  immediately,  by a notice in writing to the Company (and to the Trustee
if given by


                                       42
<PAGE>

the Holders), and upon any such declaration such principal or such lesser amount
shall become immediately due and payable.

         If an Event of Default  specified  in clause (6) or (7) of Section  5.1
occurs,  all  unpaid  principal  of and  accrued  interest  on  the  Outstanding
Securities  of that series (or such lesser  amount as may be provided for in the
Securities  of such series) shall ipso facto become and be  immediately  due and
payable  without any  declaration or other act on the part of the Trustee or any
Holder of any Security of that series.

         At any time after a  declaration  of  acceleration  with respect to the
Securities  of any  series  has been made and  before a  judgment  or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of not less than a majority in principal amount of
the Outstanding  Securities of such series, 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
         of money sufficient to pay

                           (a) all overdue  installments  of any interest on and
                  Additional  Amounts  with  respect to all  Securities  of such
                  series and any Coupon appertaining thereto,

                           (b)  the   principal   of  and  any  premium  on  any
                  Securities of such series which have become due otherwise than
                  by such  declaration of acceleration  and interest thereon and
                  any  Additional  Amounts with  respect  thereto at the rate or
                  rates borne by or provided for in such Securities,

                           (c) to the extent  that  payment of such  interest or
                  Additional   Amounts  is   lawful,   interest   upon   overdue
                  installments  of any  interest and  Additional  Amounts at the
                  rate or rates borne by or provided for in such Securities, and

                           (d)  all  sums  paid  or   advanced  by  the  Trustee
                  hereunder   and   the   reasonable   compensation,   expenses,
                  disbursements  and  advances  of the  Trustee,  its agents and
                  counsel and all other  amounts due the Trustee  under  Section
                  6.7; and

                  (2) all Events of Default with respect to  Securities  of such
         series, other than the non-payment of the principal of, any premium and
         interest on, and any  Additional  Amounts with respect to Securities of
         such series which shall have become due solely by such  declaration  of
         acceleration,  shall have been cured or waived as  provided  in Section
         5.13.

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

         Section 5.3.  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 or
         any  Coupon  appertaining  thereto  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 any
         premium on any Security or any Additional  Amounts with respect thereto
         at their Maturity,

the Company  shall,  upon demand of the  Trustee,  pay to the  Trustee,  for the
benefit of the Holders of such Securities and any Coupons appertaining  thereto,
the whole amount of money then due and payable  with respect to such  Securities
and any Coupons appertaining  thereto, with interest upon the overdue principal,
any premium  and, to the extent that payment of such  interest  shall be legally
enforceable, upon any overdue installments of interest and Additional Amounts at
the rate or rates borne by or provided for in such Securities,  and, in addition
thereto,  such further amount of money 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 to the Trustee under Section 6.7.

         If the Company fails to pay the money it is required to pay the Trustee
pursuant to the preceding  paragraph  forthwith  upon the demand of the Trustee,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial  proceeding for the collection of the money so due and unpaid,  and 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 any Coupons
appertaining thereto and collect the monies adjudged or decreed to be payable in
the  manner  provided  by law out of the  property  of the  Company or any other
obligor upon such  Securities  and any Coupons  appertaining  thereto,  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
and any Coupons appertaining thereto 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 such  Securities  or in aid of the  exercise of any power  granted
herein or therein, or to enforce any other proper remedy.

         Section 5.4.  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 of any series or the property of the Company or such other obligor or
their  creditors,  the Trustee  (irrespective  of whether the  principal  of the


                                       44
<PAGE>

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 any overdue  principal,  premium,  interest or
Additional  Amounts) shall be entitled and empowered,  by  intervention  in such
proceeding or otherwise,

                  (1) to file and prove a claim for the  whole  amount,  or such
         lesser  amount  as  may  be  provided  for  in  the  Securities  of any
         applicable  series,  of the  principal  and any  premium,  interest and
         Additional  Amounts owing and unpaid in respect of the  Securities  and
         any  Coupons  appertaining  thereto  and to file such  other  papers or
         documents  as may be necessary or advisable in order to have the claims
         of the Trustee  (including any claim for the  reasonable  compensation,
         expenses,  disbursements  and  advances of the  Trustee,  its agents or
         counsel) and of the Holders of Securities  or any Coupons  appertaining
         thereto 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 of  Securities  or any Coupons 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 of Securities or any Coupons,  to pay to the Trustee any
amount due to 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 6.7.

         Nothing  herein  contained  shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a Security
or any Coupon any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or Coupons or the rights of any Holder  thereof,  or to
authorize  the  Trustee  to vote in  respect  of the  claim of any  Holder  of a
Security or any Coupon in any such proceeding.

         Section  5.5.   Trustee  May  Enforce  Claims  without   Possession  of
Securities or Coupons.

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

premium,  interest or Additional Amounts, upon presentation of the Securities or
Coupons, or both, as the case may be, and the notation thereon of the payment if

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

                  (2) the  Holders of not less than 25% in  principal  amount of
         the  Outstanding  Securities  of such  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  such
         indemnity  as is  reasonably  satisfactory  to it  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 such
         series;


                                       46
<PAGE>

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 or any Security to affect,  disturb or prejudice the rights of
any other  such  Holders or Holders of  Securities  of any other  series,  or to
obtain or to seek to obtain  priority or preference over any other Holders or to
enforce any right under this Indenture, except in the manner herein provided and
for the equal and ratable benefit of all such Holders.

any Premium, Interest and Additional Amounts.

         Notwithstanding  any other provision in this  Indenture,  the Holder of

unconditional,  to receive payment of the principal of, any premium and (subject
to Sections 3.5 and 3.7)  interest on, and any  Additional  Amounts with respect
to,  such  Security  or  payment  of such  Coupon,  as the case  may be,  on the
respective Stated Maturity or Maturities  therefor specified in such Security or
Coupon (or, in the case of redemption, on the Redemption Date or, in the case of
repayment  at the  option of such  Holder if  provided  in or  pursuant  to this
Indenture,  on the date such  repayment  is due) and to  institute  suit for the
enforcement  of any such payment,  and such right shall not be impaired  without
the consent of such Holder.

         Section 5.9.  Restoration of Rights and Remedies.

         If the Trustee or any Holder of a Security  or a Coupon 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 each such  Holder  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 each such Holder  shall  continue as though no such  proceeding  had
been instituted.

         Section 5.10.  Rights and Remedies Cumulative.

to be exclusive of any other right or remedy, and every right and remedy, to the
extent  permitted  by law,  shall 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, to the extent permitted by law, 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 Security or
Coupon 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
or by law to the  Trustee  or to any  Holder of a  Security  or a Coupon  may be
exercised  from time to time,  and as often as may be deemed  expedient,  by the
Trustee or by such Holder, as the case may be.

         Section 5.12.  Control by Holders of Securities.

         The  Holders  of a  majority  in  principal  amount of the  Outstanding
Securities  of any 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  with  respect to the
Securities of such series and any Coupons appertaining thereto, provided that

                  (1) such  direction  shall not be in conflict with any rule of
         law or with this Indenture or with the Securities of such series,

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

                  (3) such direction is not unduly  prejudicial to the rights of
         the other  Holders of  Securities  of such  series not  joining in such
         action.

         Section 5.13.  Waiver of Past Defaults.

         The  Holders of not less than a  majority  in  principal  amount of the
Outstanding  Securities  of any  series  on  behalf  of the  Holders  of all the
Securities  of such  series and any Coupons  appertaining  thereto may waive any
past default hereunder with respect to such series and its consequences,  except
a default

                  (1) in the  payment  of  the  principal  of,  any  premium  or
         interest on, or any Additional Amounts with respect to, any Security of
         such series or any Coupons appertaining thereto, or

                  (2) in respect of a covenant or  provision  hereof which under
         Article 9 cannot be  modified  or amended  without  the  consent of the
         Holder of each Outstanding Security of such series 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.

         Section 5.14.  Waiver of Usury, Stay or Extension Laws.

         The Company  covenants  that (to the extent that it may lawfully do so)
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage  of, any usury,  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  expressly waives (to the
extent that it may  lawfully do so) all benefit or advantage of any such law and
covenants  that it will not hinder,  delay or impede the  execution of any 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.

         Section 5.15.  Undertaking for Costs.

         All parties to this Indenture agree, and each Holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this  Indenture,  or in any suit  against the  Trustee  for any action  taken or
omitted by it as Trustee,  the filing by any party  litigant in such suit of any
undertaking  to pay the  costs of such  suit,  and that  such  court  may in its
discretion  assess  reasonable  costs,  including  reasonable  attorneys'  fees,
against any party litigant in such suit having due regard to the merits and good
faith of the claims or defenses made by such party litigant;  but the provisions
of this Section 5.15 shall not apply to any suit  instituted by the Trustee,  to
any suit instituted by any Holder, or group of Holders, holding in the aggregate
more than 10% in principal amount of Outstanding Securities of any series, or to
any suit  instituted  by any Holder for the  enforcement  of the  payment of the
principal of (or premium, if any) or interest, if any, on or Additional Amounts,
if  any,  with  respect  to any  Security  on or  after  the  respective  Stated
Maturities  expressed in such  Security  (or, in the case of  redemption,  on or
after the Redemption  Date, and, in the case of repayment,  on or after the date
for  repayment)  or for the  enforcement  of the  right,  if any,  to convert or
exchange any Security into other securities in accordance with its terms.

         Section 6.1.  Certain Duties and Responsibilities

         (a) Except during the continuance of an Event of Default,

                  (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,  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


                                       49

         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 not to verify or confirm the contents thereof.

         (b) In case an Event of Default actually known to a Responsible  Office
of the Trustee has occurred and is  continuing,  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  man would  exercise  or use
under the circumstances in the conduct of his 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

                  (1) this  paragraph  (c) shall not be  construed  to limit the
         effect of paragraph (a) of this Section 6.1;

                  (2) the  Trustee  shall not be liable for any action  taken or
         error of judgment made in good faith by a Responsible  Officer,  unless

         pertinent facts;

                  (3) the Trustee shall not be liable with respect to any action
         taken or omitted to be taken by it in good faith in accordance with the
         direction  of the  Holders of a  majority  in  principal  amount of the
         Outstanding  Securities  relating  to the  time,  method  and  place of
         conducting any proceeding for any remedy  available to the Trustee,  or

         Indenture.

         Section 6.2.  Certain Rights of Trustee.

                  (1) the  Trustee  may  conclusively  rely  and  shall be fully
         protected  in acting or  refraining  from acting  upon any  resolution,
         certificate,  statement,  instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture, note, coupon or other paper
         or  document  reasonably  believed by it to be genuine and to have been
         signed or presented by the proper party or parties;

                  (2) any request or direction of the Company  mentioned  herein

         with such request or direction;

         disbursements  of its agents  and  counsel),  except any such  expense,
         disbursement  or  advance  as may  be  attributable  to  the  Trustee's
         negligence or bad faith; and

predecessor  Trustee but the  negligence  or bad faith of any Trustee  shall not
affect the rights of any other Trustee under this Section 6.7.

                  Section  6.8 and shall fail to resign  after  written  request
                  therefor by the Company or any such Holder, or

                           (c) the Trustee  shall become  incapable of acting or

                  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 or pursuant to a
                  Board  Resolution,  may remove the Trustee with respect to all
                  Securities or the  Securities of such series,  or (ii) subject
                  to Section 315(e) of the Trust  Indenture Act, any Holder of a

                  series 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
                  all  Securities  of  such  series  and  the  appointment  of a
                  successor Trustee or Trustees.

         incapable  of  acting,  or if a vacancy  shall  occur in the  office of
         Trustee for any cause,  with respect to the  Securities  of one or more
         series,  the  Company,  by or  pursuant  to a Board  Resolution,  shall
         promptly  appoint a successor  Trustee or Trustees  with respect to the
         Securities of such series (it being  understood that any such successor
         Trustee may be appointed  with respect to the Securities of one or more
         or all of such  series  and  that at any time  there  shall be only one
         Trustee with respect to the  Securities of any  particular  series) and
         shall comply with the  applicable  requirements  of Section  6.10.  If,
         within one year after such resignation,  removal or incapacity,  or the
         occurrence  of such  vacancy,  a successor  Trustee with respect to the
         Securities  of any series shall be appointed by Act of the Holders of a
         majority in  principal  amount of the  Outstanding  Securities  of such
         series delivered to the Company and the retiring Trustee, the successor
         Trustee so  appointed  shall,  forthwith  upon its  acceptance  of such
         appointment in accordance  with the applicable  requirements of Section
         6.10,  become the successor  Trustee with respect to the  Securities of
         such  series  and  to  that  extent  supersede  the  successor  Trustee
         appointed by the Company.  If no successor  Trustee with respect to the
         Securities of any series shall have been so appointed by the Company or
         the  Holders  of  Securities  and  accepted  appointment  in the manner
         required by Section 6.10,  any Holder of a Security who has been a bona
         fide  Holder of a Security  of such series for at least six months may,
         on behalf of himself and all others  similarly  situated,  petition any
         court of  competent  jurisdiction  for the  appointment  of a successor
         Trustee with respect to the Securities of such series.

         removal of the Trustee with respect to the Securities of any series and
         each appointment of a successor  Trustee with respect to the Securities
         of any series by mailing  written  notice of such event by  first-class
         mail, postage prepaid, to the Holders of Registered Securities, if


                                       55

         Register  and,  if  Securities  of such  series  are  issued  as Bearer
         Securities,  by  publishing  notice of such event once in an Authorized
         Newspaper in each Place of Payment  located  outside the United States.
         Each  notice  shall  include  the name of the  successor  Trustee  with
         respect  to the  Securities  of  such  series  and the  address  of its
         Corporate Trust Office.

                  (7) In no event shall any  retiring  Trustee be liable for the
         acts or omissions of any successor Trustee hereunder.

         Section 6.10.  Acceptance of Appointment by Successor.

                  (1) Upon the  appointment  hereunder of any successor  Trustee
         with respect to all  Securities,  such  successor  Trustee so appointed
         shall execute,  acknowledge and deliver to the Company and the retiring
         Trustee an instrument  accepting  such  appointment,  and thereupon the
         resignation or removal of the retiring  Trustee shall become  effective
         and  such  successor   Trustee,   without  any  further  act,  deed  or
         conveyance, shall become vested with all the rights, powers, trusts and
         duties  hereunder of the retiring  Trustee;  but, on the request of the
         Company or such successor Trustee,  such retiring Trustee, upon payment
         of its charges, shall execute and deliver an instrument transferring to
         such  successor  Trustee  all the  rights,  powers  and  trusts  of the
         retiring  Trustee  and,  subject to Section  10.3,  shall duly  assign,
         transfer and deliver to such  successor  Trustee all property and money
         held by such retiring Trustee  hereunder,  subject  nevertheless to its
         claim, if any, provided for in Section 6.7.

                  (2) Upon the  appointment  hereunder of any successor  Trustee
         with respect to the Securities of one or more (but not all) series, the
         Company,  the retiring Trustee and such successor Trustee shall execute
         and deliver an indenture  supplemental  hereto  wherein each  successor
         Trustee shall accept such  appointment and which (1) shall contain such
         provisions  as shall be  necessary or desirable to transfer and confirm
         to, and to vest in, such  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 hereunder by more than one Trustee, it being understood that
         nothing herein or in such supplemental  indenture shall constitute such
         Trustees co-trustees of the same trust, that each such Trustee shall be
         trustee  of a trust or trusts  hereunder  separate  and apart  from any
         trust or trusts  hereunder  administered  by any other such Trustee and
         that no  Trustee  shall be  responsible  for any  notice  given  to, or
         received  by,  or any act or  failure  to act on the part of any  other
         Trustee  hereunder,  and,  upon  the  execution  and  delivery  of such
         supplemental indenture, the resignation or removal of the


                                       56

         retiring Trustee shall become effective to the extent provided therein,
         such  retiring  Trustee  shall have no further  responsibility  for the
         exercise of rights and powers or for the  performance of the duties and
         obligations  vested in the Trustee under this Indenture with respect to
         the Securities of that or those series to which the appointment of such
         successor  Trustee  relates  other than as  hereinafter  expressly  set
         forth,  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 with respect to the  Securities of that

         contemplated  by such  supplemental  indenture,  the 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,  subject to its claim, if any, provided for in Section
         6.7.

                  (3)  Upon  request  of any  Person  appointed  hereunder  as a
         successor  Trustee,  the Company shall execute any and all  instruments
         for  more  fully  and  certainly  vesting  in and  confirming  to  such
         successor  Trustee all such  rights,  powers and trusts  referred to in
         paragraph (1) or (2) of this Section, as the case may be.

                  (4) No Person  shall  accept its  appointment  hereunder  as a
         successor  Trustee unless at the time of such acceptance such successor
         Person shall be qualified and eligible under this Article.

         Section  6.11.  Merger,  Conversion,  Consolidation  or  Succession  to
Business.

         Any  Corporation  into which the Trustee may be merged or  converted or
with which it may be consolidated, or any Corporation resulting from any merger,
conversion  or  consolidation  to which  the  Trustee  shall be a party,  or any
Corporation  succeeding by sale or otherwise to all or substantially  all of the
corporate  trust  business of the Trustee  shall be the successor of the Trustee
hereunder,  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.

         Section 6.12.  Appointment of Authenticating Agent.

         The Trustee may appoint one or more Authenticating Agents acceptable to
the  Company  with  respect to one or more series of  Securities  which shall be
authorized to act on behalf of the Trustee to authenticate Securities of that or
those series issued upon original  issue,  exchange,  registration  of transfer,
partial  redemption  or  partial  repayment  or  pursuant  to Section  3.6,  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


                                       57
<PAGE>

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 must be acceptable to the Company and, except
as  provided  in or  pursuant  to  this  Indenture,  shall  at  all  times  be a
Corporation that would be permitted by the Trust Indenture Act to act as trustee
under an indenture  qualified under the Trust Indenture Act, is authorized under
applicable  law and by its charter to act as an  Authenticating  Agent and has a
combined capital and surplus  (computed in accordance with Section  310(a)(2) of
the  Trust  Indenture  Act)  of  at  least  $50,000,000.   If  at  any  time  an
Authenticating  Agent  shall  cease  to  be  eligible  in  accordance  with  the
provisions of this Section,  it shall resign  immediately in the manner and with
the effect specified in this Section.

         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 by sale or otherwise to all or
substantially  all of the  corporate  agency or corporate  trust  business of an
Authenticating  Agent,  shall  be the  successor  of such  Authenticating  Agent
hereunder,  provided such  Corporation  shall be otherwise  eligible  under this
Section,  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 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  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,  the Trustee may appoint a successor  Authenticating
Agent which shall be acceptable to the Company and shall (i) mail written notice
of such  appointment by first-class  mail,  postage  prepaid,  to all Holders of
Registered  Securities,  if any,  of the  series  with  respect  to  which  such
Authenticating  Agent shall serve,  as their names and  addresses  appear in the
Security  Register,  and (ii) if  Securities  of the series are issued as Bearer
Securities,  publish  notice of such  appointment at least once in an Authorized
Newspaper  in the  place  where  such  successor  Authenticating  Agent  has its
principal  office if such  office is  located  outside  the United  States.  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.

         The Company agrees to pay each  Authenticating  Agent from time to time
reasonable  compensation  for its services  under this  section.  If the Trustee
makes such  payments,  it shall be entitled to be reimbursed  for such payments,
subject to the provisions of Section 6.7.

         The provisions of Sections 3.8, 6.4 and 6.5 shall be applicable to each
Authenticating Agent.

         If an  Authenticating  Agent is  appointed  with respect to one or more
series of Securities pursuant to this section, the Securities of such series may
have endorsed thereon, in addition to or in lieu of the Trustee's certificate of
authentication,  an alternate certificate of authentication in substantially the
following form:

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

         If all of the Securities of any series may not be originally  issued at
one time, and if the Trustee does not have an office  capable of  authenticating
Securities  upon  original  issuance  located  in a Place of  Payment  where the
Company  wishes to have  Securities of such series  authenticated  upon original
issuance,  the Trustee,  if so requested in writing  (which  writing need not be
accompanied by or contained in an Officer's  Certificate by the Company),  shall
appoint in accordance with this section an Authenticating Agent having an office
in a Place of Payment  designated  by the Company with respect to such series of
Securities.

         payable,  or impair the right to institute suit for the  enforcement of
         any such  payment on or after the Stated  Maturity  thereof (or, in the
         case of redemption,  on or after the Redemption Date or, in the case of
         repayment  at the  option  of the  Holder,  on or  after  the  date for
         repayment), or

                  (2)  reduce  the   percentage  in  principal   amount  of  the
         Outstanding  Securities of any series,  the consent of whose Holders is
         required for any such supplemental  indenture,  or the consent of whose
         Holders  is  required  for  any  waiver  (of  compliance  with  certain
         provisions of this  Indenture or certain  defaults  hereunder and their
         consequences)   provided   for  in  this   Indenture,   or  reduce  the
         requirements of Section 15.4 for quorum or voting, or


                                       64
<PAGE>

                  (3) modify any of the provisions of this section, Section 5.13
         or Section 10.8,  except to increase any such  percentage or to provide
         that certain other  provisions of this Indenture  cannot be modified or
         waived without the consent of the Holder of each  Outstanding  Security
         affected thereby, or

                  (4)  make any  change  that  adversely  affects  the  right to
         convert or exchange any Security into or for  securities of the Company
         or other  securities,  (whether or not issued by the  Company)  cash or
         property in accordance with its terms.

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

         It shall not be necessary  for any Act of Holders of  Securities  under
this  section  to  approve  the  particular  form of any  proposed  supplemental
indenture,  but it shall be  sufficient  if such Act shall approve the substance
thereof.

         Section 9.3.  Execution of Supplemental Indentures.

         As a condition to executing, or accepting the additional trusts created
by, any supplemental  indenture  permitted by this Article or the  modifications
thereby of the trust created by this Indenture, the Trustee shall be entitled to
receive,  and (subject to Section 315 of the Trust Indenture Act) shall be fully
protected in relying upon,  an Opinion of Counsel  stating that the execution of
such supplemental  indenture is authorized or permitted by this Indenture and an
Officer's  Certificate stating that all conditions precedent to the execution of
such supplemental indenture have been fulfilled.  The Trustee may, but shall not
be obligated to, enter into any such  supplemental  indenture  which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

         Section 9.4.  Effect of Supplemental Indentures.

         Upon the execution of any  supplemental  indenture  under this Article,
this Indenture shall be modified in accordance therewith,  and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of a Security  theretofore or thereafter  authenticated and delivered  hereunder
and of any Coupon appertaining thereto shall be bound thereby.

         Section 9.5.  Reference in Securities to Supplemental Indentures.

         Securities  of  any  series   authenticated  and  delivered  after  the
execution of any supplemental  indenture pursuant to this Article may, and shall
if required by the Trustee,  bear a notation in form  approved by the Trustee as
to any matter provided for in such supplemental  indenture. If the Company shall
so determine,  new  Securities  of any series so modified as to conform,  in the
opinion of the Trustee and the Company, to any such supplemental indenture


                                       65
<PAGE>

may be prepared and executed by the Company and  authenticated  and delivered by
the Trustee in exchange for Outstanding Securities of such series.

         Section 9.6.  Conformity with Trust Indenture Act.

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

         Section 9.7.  Notice of Supplemental Indenture.

         Promptly  after the  execution  by the  Company  and the Trustee of any
supplemental  indenture  pursuant to Section 9.2, the Company shall  transmit to
the Holders of Outstanding  Securities of any series  affected  thereby a notice
setting forth the substance of such supplemental indenture.

                                   ARTICLE 10

                                    COVENANTS

         Section  10.1.  Payment  of  Principal,   any  Premium,   Interest  and
Additional Amounts.

         The Company  covenants and agrees for the benefit of the Holders of the
Securities of each series that it will duly and punctually pay the principal of,
any  premium and  interest on and any  Additional  Amounts  with  respect to the
Securities  of such series in  accordance  with the terms  thereof,  any Coupons
appertaining thereto and this Indenture. Any interest due on any Bearer Security
on or before the  Maturity  thereof,  and any  Additional  Amounts  payable with
respect to such interest,  shall be payable only upon presentation and surrender
of the Coupons appertaining thereto for such interest as they severally mature.

         Section 10.2.  Maintenance of Office or Agency.

         The Company  shall  maintain in each Place of Payment for any series of
Securities  an Office or Agency where  Securities of such series (but not Bearer
Securities,  except as otherwise provided below, unless such Place of Payment is
located  outside the United States) may be presented or surrendered for payment,
where  Securities of such series may be surrendered for registration of transfer
or  exchange,   where   Securities  of  such  series  that  are  convertible  or
exchangeable  may be surrendered  for conversion or exchange,  and where notices
and demands to or upon the Company in respect of the  Securities  of such series
relating thereto and this Indenture may be served. If Securities of a series are
issuable as Bearer Securities,  the Company shall maintain,  subject to any laws
or regulations applicable thereto, an Office or Agency in a Place of Payment for
such series which is located outside the United States where  Securities of such
series and any Coupons appertaining thereto may be presented and surrendered for
payment; provided,  however, that if the Securities of such series are listed on
The Stock  Exchange  of the United  Kingdom  and the  Republic of Ireland or the
Luxembourg Stock Exchange or any other stock exchange located outside the United
States and such stock  exchange


                                       66
<PAGE>

shall  so  require,  the  Company  shall  maintain  a Paying  Agent  in  London,
Luxembourg or any other required city located outside the United States,  as the
case  may be,  so long as the  Securities  of such  series  are  listed  on such
exchange.  The  Company  will give prompt  written  notice to the Trustee of the
location,  and any change in the location,  of such Office or Agency.  If at any
time the Company  shall fail to maintain any such  required  Office or Agency or
shall fail to furnish the Trustee with the address thereof,  such presentations,
surrenders,  notices and demands  may be made or served at the  Corporate  Trust
Office of the  Trustee,  except  that Bearer  Securities  of such series and any
Coupons appertaining thereto may be presented and surrendered for payment at the
place  specified for the purpose with respect to such  Securities as provided in
or pursuant to this  Indenture,  and the Company hereby  appoints the Trustee as
its agent to receive all such presentations, surrenders, notices and demands.

         Except as  otherwise  provided  in or pursuant  to this  Indenture,  no
payment of principal,  premium,  interest or Additional  Amounts with respect to
Bearer  Securities shall be made at any Office or Agency in the United States or
by check mailed to any address in the United States or by transfer to an account
maintained  with a bank  located in the United  States;  provided,  however,  if
amounts owing with respect to any Bearer Securities shall be payable in Dollars,
payment of principal of, any premium or interest on and any  Additional  Amounts
with respect to any such Security may be made at the  Corporate  Trust Office of
the Trustee or any Office or Agency  designated by the Company in the Borough of
Manhattan,  The City of New York, if (but only if) payment of the full amount of
such principal,  premium,  interest or Additional Amounts at all offices outside
the United States  maintained for such purpose by the Company in accordance with
this Indenture is illegal or effectively precluded by exchange controls or other
similar restrictions.

         The  Company  may also from time to time  designate  one or more  other
Offices or Agencies  where the Securities of one or more series may be presented
or  surrendered  for any or all such  purposes and may from time to time rescind
such  designations;  provided,  however,  that no such designation or rescission
shall in any manner  relieve the Company of its obligation to maintain an Office
or Agency  in each  Place of  Payment  for  Securities  of any  series  for such
purposes.  The Company  shall give prompt  written  notice to the Trustee of any
such  designation  or  rescission  and of any change in the location of any such
other  Office or  Agency.  Unless  otherwise  provided  in or  pursuant  to this
Indenture, the Company hereby designates as the Place of Payment for each series
of  Securities  the Borough of  Manhattan,  The City of New York,  and initially
appoints  the  Corporate  Trust Office of the Trustee as the Office or Agency of
the Company in the Borough of Manhattan,  The City of New York for such purpose.
The Company may subsequently appoint a different Office or Agency in the Borough
of Manhattan, The City of New York or Milwaukee, Wisconsin for the Securities of
any series.

         Unless otherwise  specified with respect to any Securities  pursuant to
Section 3.1, if and so long as the Securities of any series (i) are  denominated
in a Foreign Currency or (ii) may be payable in a Foreign  Currency,  or so long
as it is required under any other provision of this Indenture,  then the Company
will maintain with respect to each such series of Securities, or as so required,
at least one exchange rate agent.

         Section 10.3.  Money for Securities Payments to Be Held in Trust.

         If the  Company  shall  at any time act as its own  Paying  Agent  with
respect to any series of Securities, it shall, on or before each due date of the
principal of, any premium or interest on or  Additional  Amounts with respect to
any of the  Securities  of such  series,  segregate  and hold in  trust  for the
benefit of the Persons  entitled  thereto a sum in the  currency or  currencies,
currency  unit or  units or  composite  currency  or  currencies  in  which  the
Securities of such series are payable (except as otherwise specified pursuant to
Section 3.1 for the  Securities of such series)  sufficient to pay the principal
or any premium,  interest or Additional  Amounts so becoming due until such sums
shall be paid to such Persons or otherwise  disposed of as herein provided,  and
shall promptly notify the Trustee of its action or failure so to act.

         Whenever  the  Company  shall  have one or more  Paying  Agents for any
series of  Securities,  it shall,  on or prior to each due date of the principal
of, any premium or interest on or any  Additional  Amounts  with  respect to any
Securities of such series,  deposit with any Paying Agent a sum (in the currency
or  currencies,  currency  unit or units or  composite  currency  or  currencies
described in the  preceding  paragraph)  sufficient  to pay the principal or any
premium,  interest or Additional Amounts so becoming due, such sum to be held in
trust for the benefit of the Persons entitled  thereto,  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  shall 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, that such Paying Agent shall:

                  (1) hold all sums held by it for the payment of the  principal
         of, any premium or interest on or any  Additional  Amounts with respect
         to  Securities  of such  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 provided in or pursuant to this Indenture;

                  (2) give the Trustee  notice of any default by the Company (or
         any other obligor upon the  Securities of such series) in the making of
         any payment of principal,  any premium or interest on or any Additional
         Amounts with respect to the Securities of such 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 terms as those  upon  which such sums were held by the  Company or
such Paying  Agent;  and,  upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further  liability  with respect to
such sums.


                                       68
<PAGE>

         Except as  otherwise  provided  herein or  pursuant  hereto,  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, any  premium or interest on or any
Additional  Amounts  with  respect to any  Security  of any series or any Coupon
appertaining  thereto and remaining unclaimed for two years after such principal
or any such premium or interest or any such Additional Amounts shall have become
due and  payable  shall 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 or any Coupon  appertaining  thereto 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 each Place of Payment for such
series or to be mailed to Holders of Registered  Securities  of such series,  or
both,  notice that such money remains unclaimed and that, after a date specified
therein,  which shall not be less than 30 days from the date of such publication
or mailing  nor shall it be later than two years  after such  principal  and any
premium or interest or Additional Amounts shall have become due and payable, any
unclaimed balance of such money then remaining will be repaid to the Company.

         Section 10.4.  Additional Amounts.

         If any  Securities  of a series  provide for the payment of  Additional
Amounts,  the  Company  agrees to pay to the Holder of any such  Security or any
Coupon  appertaining  thereto  Additional  Amounts as provided in or pursuant to
this  Indenture  or  such  Securities.  Whenever  in  this  Indenture  there  is
mentioned,  in any  context,  the payment of the  principal of or any premium or
interest  on, or in respect of, any  Security of any series or any Coupon or the
net  proceeds  received on 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  by the terms of such  series  established  hereby or pursuant
hereto to the extent that,  in such  context,  Additional  Amounts are,  were or
would be payable in respect thereof  pursuant to such terms, and express mention
of the payment of Additional  Amounts (if  applicable)  in any provision  hereof
shall not be  construed  as  excluding  Additional  Amounts in those  provisions
hereof where such express mention is not made.

         Except as  otherwise  provided in or pursuant to this  Indenture or the
Securities of the applicable  series,  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 such series of Securities  (or if the Securities of
such series shall not bear interest prior to Maturity,  the first day on which a
payment  of  principal  is  made),  and at least 10 days  prior to each  date of
payment of  principal  or interest if there has been any change with  respect to
the matters set forth in the below-mentioned Officer's Certificate,  the Company
shall furnish to the Trustee and the principal Paying Agent or Paying Agents, if
other than the Trustee,  an Officer's  Certificate  instructing  the Trustee and
such Paying  Agent or Paying  Agents  whether  such  payment of principal of and
premium,  if any, or interest on the  Securities of such series shall be made to
Holders of Securities of such series or


                                       69
<PAGE>

the  Coupons   appertaining   thereto  who  are  United  States  Aliens  without
withholding  for or on  account  of any tax,  assessment  or other  governmental
charge described in the Securities of such series. If any such withholding shall
be  required,  then such  Officer's  Certificate  shall  specify by country  the
amount,  if any,  required to be withheld  on such  payments to such  Holders of
Securities  or  Coupons,  and the  Company  agrees to pay to the Trustee or such
Paying Agent the Additional  Amounts  required by the terms of such  Securities.
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  Officer's
Certificate furnished pursuant to this Section 10.4.

         Section 10.5.  Limitation on Liens on Stock of Designated Subsidiaries.

         The  Company  will not,  and it will not permit any  Subsidiary  of the
Company to, at any time, directly or indirectly, create, assume, incur or permit
to exist any Indebtedness  secured by a pledge,  lien or other  encumbrance (any
pledge,  lien or other encumbrance being hereinafter in this Section referred to
as a "lien") on the capital stock of any  Designated  Subsidiary  without making
effective provision whereby the Securities then Outstanding (and, if the Company
so elects,  any other Indebtedness of the Company that is not subordinate to the
Securities  and with  respect to which the  governing  instruments  require,  or
pursuant to which the Company is otherwise  obligated  or  required,  to provide
such  security)   shall  be  equally  and  ratably  secured  with  such  secured
Indebtedness so long as such other Indebtedness  shall be secured.  For purposes
of this Section 10.5 only,  "Indebtedness," in addition to those items specified
in Section 1.1 hereof,  shall include any obligation of, or any such  obligation
guaranteed  by, any Person for the payment of amounts due under a swap agreement
or other similar instrument or agreement,  or foreign currency hedge exchange or
similar instrument or agreement.

         If the Company  shall  hereafter  be required to secure the  Securities
equally and ratably with any other  Indebtedness  pursuant to this section,  (i)
the  Company  will  promptly  deliver to the  Trustee an  Officers'  Certificate
stating that the foregoing  covenant has been complied  with,  and an Opinion of
Counsel stating that in the opinion of such counsel,  the foregoing covenant has
been  complied  with and that any  instruments  executed  by the  Company or any
Subsidiary of the Company in the  performance of the foregoing  covenant  comply
with the  requirements of the foregoing  covenant and (ii) the Trustee is hereby
authorized  to enter into an indenture or agreement  supplemental  hereto and to
take such action,  if any, as it may deem  advisable to enable it to enforce the
rights of the holder of the Securities so secured.

         Section  10.6.  Limitation  Upon Sales of Capital  Stock of  Designated
Subsidiaries.

         The Company will not sell,  transfer or otherwise dispose of (except to
a Subsidiary, which agrees in writing to hold such transferred shares subject to
the  terms  of  this  Section  10.6),  and it will  not  permit  any  Designated
Subsidiary to sell,  transfer or otherwise  dispose of (except to the Company or
to a Subsidiary, which agrees in writing to hold such transferred shares subject
to the terms of this Section 10.6),  any shares of Capital Stock of a Designated
Subsidiary,


                                       70
<PAGE>

unless the entire Capital Stock of such Designated  Subsidiary at the time owned
by the Company and its Designated  Subsidiaries shall be disposed of at the same
time for a  consideration  consisting of cash or other  property,  which, in the
opinion of the Board of Directors, is at least equal to the fair value thereof.

         Section 10.7.  Corporate Existence.

         Subject  to  Article  8, the  Company  shall do or cause to be done all
things  necessary  to preserve  and keep in full force and effect its  corporate
existence and that of each of its Designated  Subsidiaries  and their respective
rights  (charter and  statutory) and  franchises;  provided,  however,  that the
foregoing  shall not obligate the Company or any of its Designated  Subsidiaries
to preserve any such right or  franchise  if the Company or any such  Designated
Subsidiary shall determine that the preservation  thereof is no longer desirable
in the conduct of its business or the business of such Designated Subsidiary and
that the loss  thereof is not  disadvantageous  in any  material  respect to any
Holder.

         Section 10.8.  Waiver of Certain Covenants.

         The  Company  may omit in any  particular  instance  to comply with any
term,  provision  or  condition  set forth in  Section  10.5,  10.6 or 10.7 with
respect to the  Securities of any series if before the time for such  compliance
the  Holders  of at least a  majority  in  principal  amount of the  Outstanding
Securities  of such  series,  by Act of such  Holders,  either  shall waive such
compliance in such instance or generally shall have waived  compliance with such
term, provision or condition,  but no such waiver shall extend to or affect such
term,  provision 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 term,  provision or condition shall
remain in full force and effect.

         Section 10.9.  Company  Statement as to  Compliance;  Notice of Certain
Defaults.

                  (1) The Company shall deliver to the Trustee,  within 120 days
         after the end of each fiscal year, a written  statement (which need not
         be contained in or accompanied by an Officer's  Certificate)  signed by
         the principal executive officer, the principal financial officer or the
         principal accounting officer of the Company, stating that

                           (a) a review of the  activities of the Company during
                  such year and of its performance under this Indenture has been
                  made under his or her supervision, and

                           (b) to the  best of his or her  knowledge,  based  on
                  such  review,  (a)  the  Company  has  complied  with  all the
                  conditions  and covenants  imposed on it under this  Indenture
                  throughout  such year,  or, if there has been a default in the
                  fulfillment of any such condition or covenant, specifying each
                  such  default  known to him or her and the  nature  and status
                  thereof, and (b) no event has occurred and is continuing which
                  is, or after notice or lapse of time or both would become,  an


                                       71
<PAGE>

                  Event of  Default,  or, if such an event has  occurred  and is
                  continuing,  specifying  each such event  known to him and the
                  nature and status thereof.

                  (2) The Company shall deliver to the Trustee, within five days
         after the occurrence thereof, written notice of any Event of Default or
         any event which after  notice or lapse of time or both would  become an
         Event of Default pursuant to clause (4) of Section 5.1.

                  (3) The Trustee  shall have no duty to monitor  the  Company's
         compliance  with the covenants  contained in this Article 10 other than
         as specifically set forth in this Section 10.9.

                                   ARTICLE 11

                            REDEMPTION OF SECURITIES

         Section 11.1.  Applicability of Article.

         Redemption  of Securities of any series at the option of the Company as

herein or pursuant hereto) this Article.

         Section 11.2.  Election to Redeem; Notice to Trustee.

         Section 11.3.  Selection by Trustee of Securities to be Redeemed.

         If less than all of the  Securities  of any series  with the same issue
date,  interest  rate or  formula,  Stated  Maturity  and other  terms are to be
redeemed,  the  particular  Securities to be redeemed shall be selected not 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 which may provide for the
selection  for  redemption  of portions of the  principal  amount of  Registered
Securities of such series;  provided,  however,  that no such partial redemption
shall reduce the portion of the  principal  amount of a  Registered  Security of
such series not redeemed to less than the minimum denomination for a Security of
such series established herein or pursuant hereto.


                                       72
<PAGE>

         The  Trustee  shall  promptly  notify  the  Company  and  the  Security
Registrar  (if other than  itself) 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 of such Securities which has been or is to be redeemed.

         Unless  otherwise  specified  in or pursuant to this  Indenture  or the
Securities  of any series,  if any Security  selected for partial  redemption is
converted  into other  securities of the Company or exchanged for  securities of
another  issuer in part before  termination  of the conversion or exchange right
with respect to the portion of the Security so selected,  the converted  portion
of such Security  shall be deemed (so far as may be) to be the portion  selected
for  redemption.  Securities  which have been  converted or  exchanged  during a
selection  of  Securities  to be  redeemed  shall be treated  by the  Trustee as
Outstanding for the purpose of such selection.

         Section 11.4.  Notice of Redemption.

         Notice of redemption  shall be given in the manner  provided in Section
1.6, not less than 30 nor more than 60 days prior to the Redemption Date, unless
a shorter period is specified in the  Securities to be redeemed,  to the Holders
of  Securities  to be redeemed.  Failure to give notice by mailing in the manner
herein  provided  to the  Holder of any  Registered  Securities  designated  for
redemption  as a whole or in  part,  or any  defect  in the  notice  to any such
Holder,  shall not affect the validity of the  proceedings for the redemption of
any other Securities or portion thereof.

         Any notice that is mailed to the Holder of any Registered Securities in
the manner  herein  provided  shall be  conclusively  presumed to have been duly
given, whether or not such Holder receives the notice.

         All notices of redemption shall state:

                  (1)      the Redemption Date,

                  (2)      the Redemption Price,

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

                  (4) in case any  Security is to be redeemed in part only,  the
         notice which relates to such Security shall state that on and after the
         Redemption  Date,  upon surrender of such Security,  the Holder of such
         Security will receive,  without charge, a new Security or Securities of
         authorized  denominations  for the principal  amount thereof  remaining
         unredeemed,


                                       73
<PAGE>

                  (5) that, on the Redemption  Date, the Redemption  Price shall
         become due and payable upon each such Security or portion thereof to be
         redeemed,  and, if  applicable,  that  interest  thereon shall cease to
         accrue on and after said date,

                  (6) the place or places  where such  Securities,  together (in
         the case of Bearer Securities) with all Coupons  appertaining  thereto,
         if any,  maturing after the Redemption  Date, are to be surrendered for
         payment of the Redemption Price and any accrued interest and Additional
         Amounts pertaining thereto,

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

                  (8) that,  unless otherwise  specified in such notice,  Bearer
         Securities of any series,  if any,  surrendered  for redemption must be
         accompanied  by all Coupons  maturing  subsequent to the date fixed for
         redemption or the amount of any such missing  Coupon or Coupons will be
         deducted  from the  Redemption  Price,  unless  security  or  indemnity
         satisfactory  to the  Company,  the  Trustee  and any  Paying  Agent is
         furnished,

                  (9) if Bearer  Securities of any series are to be redeemed and
         no Registered Securities of such series are to be redeemed, and if such
         Bearer  Securities  may be  exchanged  for  Registered  Securities  not
         subject to redemption on the Redemption Date pursuant to Section 3.5 or
         otherwise,  the last date, as determined by the Company,  on which such
         exchanges may be made,

                  (10)  in the  case  of  Securities  of  any  series  that  are
         convertible  into Common Stock of the Company or exchangeable for other
         securities, the conversion or exchange price or rate, the date or dates
         on  which  the  right to  convert  or  exchange  the  principal  of the
         Securities of such series to be redeemed will commence or terminate and
         the  place or places  where  such  Securities  may be  surrendered  for
         conversion or exchange, and

                  (11) the CUSIP number or the Euroclear or the Cedel  reference
         numbers  of such  Securities,  if any (or any other  numbers  used by a
         Depository to identify such Securities).

         A notice of redemption  published as  contemplated  by Section 1.6 need
not identify particular Registered 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 Company's  request,  by the
Trustee in the name and at the expense of the Company.

         Section 11.5.  Deposit of Redemption Price.

         On or prior to any Redemption  Date,  the Company shall  deposit,  with
respect to the  Securities  of any  series  called for  redemption  pursuant  to
Section  11.4,  with the  Trustee or with a Paying  Agent (or, if the Company is
acting as its own  Paying  Agent,  segregate  and hold in trust


                                       74
<PAGE>

as  provided  in  Section  10.3) an amount of money in the  applicable  Currency
sufficient to pay the Redemption  Price of, and (except if the  Redemption  Date
shall be an  Interest  Payment  Date,  unless  otherwise  specified  pursuant to
Section 3.1 or in the  Securities  of such  series) any accrued  interest on and
Additional Amounts with respect thereto, all such Securities or portions thereof
which are to be redeemed on that date.

         Section 11.6.  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 and the Coupons for such
interest appertaining to any Bearer Securities so to be redeemed,  except to the
extent  provided  below,  shall be void. Upon surrender of any such Security for
redemption in accordance  with said notice,  together with all Coupons,  if any,
appertaining  thereto maturing after the Redemption Date, such Security shall be
paid by the Company at the Redemption Price,  together with any accrued interest
and Additional Amounts to the Redemption Date; provided,  however,  that, except
as otherwise  provided in or pursuant to this Indenture or the Bearer Securities
of such  series,  installments  of interest on Bearer  Securities  whose  Stated
Maturity  is on or prior to the  Redemption  Date  shall be  payable  only  upon
presentation  and surrender of Coupons for such interest (at an Office or Agency
located outside the United States except as otherwise provided in Section 10.2),
and provided,  further,  that,  except as otherwise  specified in or pursuant to
this  Indenture or the  Registered  Securities of such series,  installments  of
interest on Registered  Securities  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
Regular  Record Dates  therefor  according to their terms and the  provisions of
Section 3.7.

         If  any  Bearer  Security  surrendered  for  redemption  shall  not  be
accompanied by all appurtenant  Coupons maturing after the Redemption Date, such
Security may be paid after  deducting from the Redemption  Price an amount equal
to the face amount of all such missing Coupons, or the surrender of such missing
Coupon or  Coupons  may be waived by the  Company  and the  Trustee  if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent  harmless.  If thereafter  the Holder of such Security
shall  surrender to the Trustee or any Paying  Agent any such missing  Coupon in
respect of which a  deduction  shall have been made from the  Redemption  Price,
such  Holder  shall be entitled  to receive  the amount so  deducted;  provided,
however, that any interest or Additional Amounts represented by Coupons shall be
payable only upon  presentation  and  surrender of those Coupons at an Office or
Agency  for such  Security  located  outside  of the  United  States  except  as
otherwise provided in Section 10.2.

         If any  Security  called  for  redemption  shall  not be so  paid  upon
surrender  thereof for  redemption,  the principal and any premium,  until paid,
shall bear interest from the Redemption Date at the rate prescribed  therefor in
the Security.

         Section 11.7.  Securities Redeemed in Part.

         Any  Registered  Security which is to be redeemed only in part shall be
surrendered at any Office or Agency for such Security  (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 Registered  Security or Securities of the
same  series,  containing  identical  terms and  provisions,  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.  If a Security in global form is so surrendered,  the Company shall
execute,  and the Trustee shall authenticate and deliver to the U.S.  Depository
or other  Depository  for such  Security in global form as shall be specified in
the Company Order with respect thereto to the Trustee, without service charge, a
new Security in global form in a  denomination  equal to and in exchange for the
unredeemed  portion  of  the  principal  of  the  Security  in  global  form  so
surrendered.

                                  SINKING FUNDS

         Section 12.1.  Applicability of Article.

         The  provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series,  except as otherwise  permitted or
required in or pursuant to this  Indenture or any Security of such series issued
pursuant to this Indenture.

         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 such series is herein  referred to as an  "optional
sinking fund payment". If provided for 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  12.2.  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 and this Indenture.

         Section 12.2.  Satisfaction of Sinking Fund Payments with Securities.

         The Company may, in satisfaction of all or any part of any sinking fund
payment with respect to the  Securities of any series to be made pursuant to the
terms of such  Securities  (1)  deliver  Outstanding  Securities  of such series
(other than any of such  Securities  previously  called for redemption or any of
such  Securities  in  respect of which  cash  shall  have been  released  to the
Company),  together in the case of any Bearer Securities of such series with all
unmatured Coupons appertaining  thereto, and (2) apply as a credit Securities of
such  series  which have been  redeemed  either at the  election  of the Company
pursuant to the terms of such series of Securities


                                       76
<PAGE>

or through the application of permitted  optional sinking fund payments pursuant
to the terms of such  Securities,  provided that such series of 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 fund payment  shall be reduced  accordingly.  If, as a result of
the  delivery  or credit of  Securities  of any series in lieu of cash  payments
pursuant to this Section 12.2, the principal amount of Securities of such series
to be redeemed in order to satisfy the  remaining  sinking fund payment shall be
less than  $100,000,  the Trustee  need not call  Securities  of such series for
redemption,  except upon Company Request, and such cash payment shall be held by
the Trustee or a Paying  Agent and applied to the next  succeeding  sinking fund
payment,  provided,  however, that the Trustee or such Paying Agent shall at the
request of the Company from time to time pay over and deliver to the Company any
cash payment so being held by the Trustee or such Paying Agent upon  delivery by
the Company to the Trustee of Securities of that series purchased by the Company
having an unpaid  principal  amount  equal to the cash  payment  requested to be
released to the Company.

         Section 12.3.  Redemption of Securities for Sinking Fund.

         Not less than 75 days prior to each  sinking  fund payment date for any
series of  Securities,  the Company  shall  deliver to the Trustee an  Officer's
Certificate  specifying  the amount of the next ensuing  mandatory  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  delivering  and  crediting  of
Securities of that series pursuant to Section 12.2, and the optional amount,  if
any, to be added in cash to the next ensuing mandatory sinking fund payment, and
will also  deliver to the  Trustee  any  Securities  to be so  credited  and not
theretofore  delivered.  If such Officer's Certificate shall specify an optional
amount to be added in cash to the next ensuing  mandatory  sinking fund payment,
the Company shall  thereupon be obligated to pay the amount  therein  specified.
Not less than 60 days before each such  sinking  fund  payment  date the Trustee
shall select the  Securities  to be redeemed upon such sinking fund payment date
in the manner  specified  in  Section  11.3 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  11.4.  Such notice  having  been duly  given,  the
redemption  of such  Securities  shall be made upon the terms and in the  manner
stated in Sections 11.6 and 11.7.

                                   ARTICLE 13

                       REPAYMENT AT THE OPTION OF HOLDERS

         Section 13.1.  Applicability of Article.

         Securities  of any  series  which are  repayable  at the  option of the
Holders  thereof before their Stated Maturity shall be repaid in accordance with
the terms of the  Securities  of such series.  The  repayment  of any  principal
amount of Securities  pursuant to such option of the Holder to require repayment
of Securities  before their Stated Maturity,  for purposes of Section 3.9, shall
not  operate  as a  payment,  redemption  or  satisfaction  of the  Indebtedness
represented  by such


                                       77
<PAGE>

Securities  unless  and until the  Company,  at its  option,  shall  deliver  or
surrender  the same to the Trustee  with a  directive  that such  Securities  be
cancelled.  Notwithstanding  anything to the contrary  contained in this Section
13.1, in connection  with any repayment of  Securities,  the Company may arrange
for the purchase of any Securities by an agreement  with one or more  investment
bankers or other purchasers to purchase such Securities by paying to the Holders
of such  Securities on or before the close of business on the repayment  date an
amount not less than the repayment  price payable by the Company on repayment of
such Securities, and the obligation of the Company to pay the repayment price of
such Securities  shall be satisfied and discharged to the extent such payment is
so paid by such purchasers.

                                   ARTICLE 14

                        SECURITIES IN FOREIGN CURRENCIES

         Section 14.1.  Applicability of Article.

         Whenever  this  Indenture  provides  for  (i)  any  action  by,  or the
determination  of any of the rights of,  Holders of  Securities of any series in
which not all of such Securities are  denominated in the same Currency,  or (ii)
any  distribution  to Holders of Securities,  in the absence of any provision to
the  contrary in the form of Security  of any  particular  series or pursuant to
this  Indenture  or the  Securities,  any  amount  in  respect  of any  Security
denominated  in a Currency  other  than  Dollars  shall be treated  for any such
action or distribution as that amount of Dollars that could be obtained for such
amount on such  reasonable  basis of  exchange  and as of the  record  date with
respect  to  Registered  Securities  of such  series  (if any) for such  action,
determination  of rights or  distribution  (or, if there shall be no  applicable
record date,  such other date  reasonably  proximate to the date of such action,
determination of rights or distribution) as the Company may specify in a written
notice to the Trustee.

         Section 15.1.  Purposes for Which Meetings May Be Called.

         A meeting of Holders of  Securities  of any series may be called at any

         Section 15.2.  Call, Notice and Place of Meetings.

                  (1) The  Trustee  may at any time call a meeting of Holders of

         outside


                                       78
<PAGE>

         the  United  States as the  Trustee  shall  determine.  Notice of every
         meeting of Holders of Securities of any series,  setting forth the time
         and the place of such meeting and in general terms the action  proposed
         to be taken at such meeting,  shall be given, in the manner provided in
         Section  1.6, not less than 21 nor more than 180 days prior to the date
         fixed for the meeting.

                  (2) In case at any time the Company (by or pursuant to a Board
         Resolution)  or the Holders of at least 10% in principal  amount of the
         Outstanding  Securities of any series shall have  requested the Trustee
         to call a meeting of the Holders of  Securities  of such series for any
         purpose  specified in Section 15.1, by written request setting forth in
         reasonable  detail the action proposed to be taken at the meeting,  and
         the  Trustee  shall  not  have  mailed  notice  of or  made  the  first
         publication  of the notice of such meeting within 21 days after receipt
         of such request  (whichever shall be required  pursuant to Section 1.6)
         or shall not  thereafter  proceed  to cause the  meeting  to be held as
         provided herein,  then the Company or the Holders of Securities of such
         series in the amount above specified, as the case may be, may determine
         the time and the place in the  Borough  of  Manhattan,  The City of New
         York,  or,  if  Securities  of such  series  are to be issued as Bearer

         Section 15.4.  Quorum; Action.

         The  Persons  entitled to vote a majority  in  principal  amount of the
Outstanding  Securities of a series shall constitute a quorum for any meeting of
Holders of  Securities  of such  series.  In the  absence of a quorum  within 30
minutes after the time  appointed for any such meeting,  the meeting  shall,  if
convened at the request of Holders of Securities  of such series,  be dissolved.
In any other case the meeting may be adjourned  for a period of not less than 10
days as determined by the chairman of the meeting  prior to the  adjournment  of
such  meeting.  In the  absence  of a quorum  at any  reconvened  meeting,  such
reconvened  meeting  may be further  adjourned  for a period of not less than 10
days as determined by the chairman of the meeting  prior to the  adjournment  of
such  reconvened  meeting.  Notice of the  reconvening of any adjourned  meeting
shall be given as provided in Section  15.2(1),  except that such notice need be
given only once not less than five days  prior to the date on which the  meeting
is scheduled to be reconvened. Notice of the reconvening of an adjourned meeting
shall state expressly the percentage, as


                                       79
<PAGE>

provided  above, of the principal  amount of the Outstanding  Securities of such
series which shall constitute a quorum.

         Except as  limited  by the  proviso  to  Section  9.2,  any  resolution
presented to a meeting or adjourned meeting duly reconvened at which a quorum is
present as aforesaid may be adopted only by the affirmative  vote of the Holders
of a majority in principal amount of the Outstanding  Securities of that series;
provided,  however,  that,  except as limited by the proviso to Section 9.2, any
resolution  with  respect  to any  request,  demand,  authorization,  direction,
notice, consent, waiver or other Act which this Indenture expressly provides may
be made, given or taken by the Holders of a specified percentage,  which is less
than a majority,  in principal amount of the Outstanding  Securities of a series
may be adopted at a meeting or an adjourned meeting duly reconvened and at which
a quorum is present as aforesaid by the affirmative  vote of the Holders of such
specified  percentage in principal amount of the Outstanding  Securities of such
series.

         Any  resolution  passed or decision  taken at any meeting of Holders of
Securities  of any series duly held in  accordance  with this  section  shall be
binding  on all the  Holders  of  Securities  of  such  series  and the  Coupons
appertaining thereto, whether or not such Holders were present or represented at
the meeting.

         Section 15.5.  Determination of Voting Rights;  Conduct and Adjournment
of Meetings.

                  (1)  Notwithstanding  any other  provisions of this Indenture,
         the  Trustee  may  make  such  reasonable  regulations  as it may  deem
         advisable  for any meeting of Holders of  Securities  of such series in
         regard to proof of the holding of  Securities of such series and of the
         appointment of proxies and in regard to the  appointment  and duties of
         inspectors  of  votes,  the  submission  and  examination  of  proxies,
         certificates  and other  evidence of the right to vote,  and such other
         matters  concerning  the  conduct  of  the  meeting  as it  shall  deem
         appropriate.  Except as  otherwise  permitted  or  required by any such
         regulations,  the holding of  Securities  shall be proved in the manner
         specified  in Section  1.4 and the  appointment  of any proxy  shall be
         proved  in  the  manner  specified  in  Section  1.4 or by  having  the
         signature of the person  executing the proxy witnessed or guaranteed by
         any trust company,  bank or banker authorized by Section 1.4 to certify
         to the holding of Bearer Securities.  Such regulations may provide that
         written instruments  appointing proxies,  regular on their face, may be
         presumed valid and genuine  without the proof  specified in Section 1.4
         or other proof.

                  (2) The Trustee shall, by an instrument in writing,  appoint a
         temporary  chairman of the meeting,  unless the meeting shall have been
         called by the  Company or by  Holders  of  Securities  as  provided  in
         Section 15.2(2), in which case the Company or the Holders of Securities
         of the series  calling the  meeting,  as the case may be, shall in like
         manner  appoint  a  temporary  chairman.  A  permanent  chairman  and a
         permanent  secretary  of the  meeting  shall be  elected by vote of the
         Persons  entitled  to  vote  a  majority  in  principal  amount  of the
         Outstanding Securities of such series represented at the meeting.

                  (3) At any  meeting,  each Holder of a Security of such series
         or proxy shall be entitled to one vote for each $1,000 principal amount
         of  Securities  of such series held or  represented  by him;  provided,
         however,  that no vote  shall  be cast or  counted  at any  meeting  in
         respect of any Security  challenged as not Outstanding and ruled by the
         chairman  of the  meeting to be not  Outstanding.  The  chairman of the
         meeting  shall have no right to vote,  except as a Holder of a Security
         of such series or proxy.

                  (4) Any  meeting of Holders of  Securities  of any series duly
         called  pursuant  to Section  15.2 at which a quorum is present  may be
         adjourned  from time to time by Persons  entitled to vote a majority in
         principal   amount  of  the  Outstanding   Securities  of  such  series
         represented at the meeting; and the meeting may be held as so adjourned
         without further notice.

         Section 15.6.  Counting Votes and Recording Action of Meetings.

         The vote upon any  resolution  submitted  to any  meeting of Holders of
Securities  of any  series  shall  be by  written  ballots  on  which  shall  be
subscribed  the  signatures  of the Holders of  Securities  of such series or of
their  representatives  by proxy and the principal amounts and serial numbers of
the  Outstanding  Securities  of such series held or  represented  by them.  The
permanent  chairman of the meeting  shall  appoint two  inspectors  of votes who
shall count all votes cast at the meeting for or against any  resolution and who
shall make and file with the  secretary of the meeting  their  verified  written
reports in  triplicate of all votes cast at the meeting.  A record,  at least in
triplicate,  of the  proceedings of each meeting of Holders of Securities of any
series  shall be  prepared  by the  secretary  of the meeting and there shall be
attached to said record the original  reports of the  inspectors of votes on any
vote by ballot  taken  thereat  and  affidavits  by one or more  persons  having
knowledge  of the facts  setting  forth a copy of the notice of the  meeting and
showing  that said  notice  was  given as  provided  in  Section  15.2  and,  if
applicable,  Section  15.4.  Each  copy  shall be  signed  and  verified  by the
affidavits of the  permanent  chairman and secretary of the meeting and one such
copy  shall be  delivered  to the  Company  and  another  to the  Trustee  to be
preserved by the Trustee,  the latter to have attached thereto the ballots voted
at the meeting.  Any record so signed and verified shall be conclusive  evidence
of the matters therein stated.
