                                       10

<PAGE>



           In any case where several matters are required to be certified by, or
covered by an opinion of, any specified  Person,  it is not  necessary  that all
such  matters  be  certified  by, or covered by the  opinion  of,  only one such
Person,  or that they be so certified or covered by only one  document,  but one
such Person may certify or give an opinion  with respect to some matters and one
or more other such Persons as to other matters,  and any such Person may certify
or give an opinion as to such matters in one or several documents.

           Any certificate or opinion of an officer of the Company may be based,
insofar as it relates to legal  matters,  upon a  certificate  or opinion of, or
representations  by,  counsel,  unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or  representations
with  respect to  matters  upon  which his  certificate  or opinion is based are
erroneous.

           Any such  certificate or Opinion of Counsel may be based,  insofar as
it  relates  to  factual   matters,   upon  a  certificate  or  opinion  of,  or
representations  by, an officer or  officers  of the  Company  stating  that the
information  with respect to such factual  matters is in the  possession  of the
Company unless such counsel knows,  or in the exercise of reasonable care should
know,  that the certificate or opinion or  representations  with respect to such
matters are erroneous.

           Where any Person is  required  to make,  give or execute  two or more
applications,  requests, consents,  certificates,  statements, opinions or other
instruments  under this Indenture,  they may, but need not, be consolidated  and
form one instrument.

Section 104.         ACTS OF HOLDERS.

           (a) Any request, demand,  authorization,  direction, notice, consent,
waiver  or  other  action  provided  by this  Indenture  to be given or taken by
Holders  may  be  embodied  in and  evidenced  by one  or  more  instruments  of
substantially  similar  tenor  signed by such Holders in person or by agent duly
appointed  in  writing.  If  Securities  of a  series  are  issuable  as  Bearer
Securities,  any request,  demand,  authorization,  direction,  notice, consent,
waiver or other action provided by this Indenture to be given by Holders of such
series may, alternatively, be embodied in and evidenced by the record of Holders
of  Securities of such series  voting in favor  thereof,  either in person or by
proxies duly  appointed in writing,  at any meeting of Holders of  Securities of
such series duly called and held in  accordance  with the  provisions of Article
Thirteen,  or a combination of such  instruments and any such record.  Except as
herein  otherwise  expressly  provided,  such action shall become effective when
such  instrument or  instruments  or record or both are delivered to the Trustee
for the  appropriate  series of  Securities  and,  where it is hereby  expressly
required,  to the Company.  Such  instrument or instruments  and any such record
(and the action  embodied  therein and evidenced  thereby) are herein  sometimes
referred to as the "Act" of the Holders  signing such  instrument or instruments
or so voting at any such meeting.  Proof of execution of any such  instrument or
of a writing  appointing  any such  agent,  or of the holding by any Person of a
Security,  shall be sufficient for any purpose of this Indenture and (subject to
Section 601)  conclusive in favor of the Trustee for the  appropriate  series of
Securities and the Company and any agent of such Trustee or the Company, if made
in the manner provided in this Section.  The record of any meeting of Holders of
Securities shall be proved in the manner provided in Section 1306.

           The Company may at its  discretion  set a record date for purposes of
determining the identity of Holders of Registered Securities entitled to vote or
consent to any  action by vote or consent  authorized  or  permitted  under this
Indenture,  but the Company shall have no obligation to do so. If not set by the
Company prior to the first solicitation of Holders of Registered Securities of a
particular  series made by any Person in respect of any such action,  or, in the
case of any such vote,  prior to such vote,  the record date for any such action
or vote  shall  be 30 days  prior  to the  first  solicitation  of such  vote or
consent.  Upon the fixing of such a record date,  those persons who were Holders
of Registered Securities at such record date (or their duly designated

                                       11

<PAGE>



proxies),  and only  those  persons,  shall be  entitled  with  respect  to such
Registered  Securities  to take such  action by vote or consent or to revoke any
vote or consent  previously  given,  whether or not such persons  continue to be
Holders after such record date.

           (b) The fact  and date of the  execution  by any  Person  of any such
instrument  or  writing  may be proved  by the  affidavit  of a witness  of such
execution or by the certificate of any notary public or other officer authorized
by law to take acknowledgments of deeds,  certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution  is by an officer of a  corporation  or  association  or a member of a
partnership,  or an official of a public or governmental body, on behalf of such
corporation,  association,  partnership or public or  governmental  body or by a
fiduciary,  such certificate or affidavit shall also constitute sufficient proof
of his authority.

           (c) The fact  and date of the  execution  by any  Person  of any such
instrument or writing,  or the authority of the Person  executing the same,  may
also be proved in any other manner which the Trustee for the appropriate  series
of Securities deems sufficient.

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

           (e) The principal amount and serial numbers of Bearer Securities held
by any Person, and the date of holding the same, may be proved by the production
of such Bearer Securities or by a certificate  executed,  as depositary,  by any
trust company,  bank, banker or other  depositary,  wherever  situated,  if such
certificate   shall  be  deemed  by  the  Trustee  for  such  Securities  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 such Trustee to be  satisfactory.  The Trustee for such Securities and
the Company  may assume that such  ownership  of any Bearer  Security  continues
until (1)  another  certificate  or  affidavit  bearing a later  date  issued in
respect of the same Bearer  Security is  produced,  (2) such Bearer  Security is
produced  to such  Trustee by some other  Person,  (3) such  Bearer  Security is
surrendered in exchange for a Registered  Security,  or (4) such Bearer Security
is no longer  Outstanding.  The  principal  amount and serial  numbers of Bearer
Securities  held by any Person,  and the date of holding  the same,  may also be
proved in any other manner which the Company and the Trustee for such Securities
deem sufficient.

           (f) Subject to Section 115, in determining whether the Holders of the
requisite  principal  amount of Outstanding  Securities  have given any request,
demand,   authorization,   direction,  notice,  consent  or  waiver  under  this
Indenture, the principal amount of an OID Security that may be counted in making
such  determination and that shall be deemed to be Outstanding for such purposes
shall be equal to the  amount of the  principal  thereof  that  would be due and
payable upon a declaration of acceleration of the Maturity  thereof  pursuant to
Section  502 at the  time the  taking  of such  action  by the  Holders  of such
requisite principal amount is evidenced to the Trustee for such Securities.

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

waiver or Act of  Holders  or other  documents  provided  or  permitted  by this
Indenture to be made upon, given or furnished to, or filed with,

                     (1) the Trustee for a series of Securities by any Holder or
           by the Company  shall be sufficient  for every  purpose  hereunder if
           made, given, furnished or filed in writing to or with such Trustee at
           its   Corporate   Trust   Office,   Attention:    Corporate   Trustee
           Administration Department, or if sent by facsimile transmission, to a
           facsimile number provided by the Trustee,  with a copy mailed,  first
           class  postage  prepaid to the  Trustee  addressed  to it as provided
           above, or
                     (2) the Company by such  Trustee or by any Holder  shall be
           sufficient  for  every  purpose  hereunder  (except  as  provided  in
           paragraphs  (3),  (4) and (5) of Section 501) if furnished in writing
           and mailed, first class postage prepaid, addressed in the case of the
           Company to it 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 such  Trustee by the  Company,  or if sent by
           facsimile transmission, to a facsimile number provided to the Trustee
           by the Company,  with a copy mailed,  first class postage prepaid, to
           the Company addressed to it as provided above.

Section 106.         NOTICE TO HOLDERS; WAIVER.

           Where this Indenture provides for notice to Holders of any event, (1)
such notice shall be  sufficiently  given  (unless  otherwise  herein  expressly
provided) to Holders of Registered  Securities  if in writing and mailed,  first
class postage prepaid,  to each Holder 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 (unless  otherwise herein expressly
provided)  to  Holders  of Bearer  Securities  who have  filed  their  names and
addresses  with the Trustee for such purpose within the previous two years if in
writing and  mailed,  first class  postage  prepaid,  to each such Holder at his
address  as so filed not later  than the latest  date and not  earlier  than the
earliest date prescribed for the giving of such notice,  or to all other Holders
of Bearer  Securities if published in an Authorized  Newspaper on a Business Day
at least twice,  the first such  publication to be not earlier than the earliest
date,  and the second  such  publication  to be not later than the latest  date,
prescribed herein 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  mailed in the manner  prescribed by this
Indenture  shall be deemed to have been  given  whether or not  received  by any
particular  Holder.  In case by reason of the suspension of regular mail service
or by reason of any other cause it shall be impracticable to give such notice to
Holders of Registered  Securities by mail,  then such  notification  as shall be
made with the  approval of the Trustee for such  Securities  shall  constitute a
sufficient notification for every purpose hereunder.

           In case by reason of the  suspension 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 Bearer  Securities as provided  above,  then
such  notification  to  Holders of Bearer  Securities  as shall be made with the
approval of the Trustee for such Securities shall constitute  sufficient  notice
to such Holders for every purpose hereunder.  Neither the failure to give notice
by publication to Holders of Bearer Securities as provided above, nor any defect
in any  notice so  published,  shall  affect  the  sufficiency  of any notice to
Holders of Registered Securities given as provided herein.

<PAGE>



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

Section 107.         CONFLICT WITH TRUST INDENTURE ACT.

           If any  provision  hereof  limits,  qualifies or  conflicts  with the
duties  imposed by any of Sections  310  through  317,  inclusive,  of the Trust
Indenture  Act through the  operation of Section  318(c)  thereof,  such imposed
duties shall control.

coupons 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 111.         BENEFITS OF INDENTURE.

           Nothing in this  Indenture  or in the  Securities  or in any  coupons
appertaining thereto, expressed or implied, shall give to any Person, other than
the  parties  hereto,  any  Paying  Agent,  any  Security  Registrar  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 112.         GOVERNING LAW.

           This Indenture and the Securities  shall be governed by and construed
in accordance with the laws of the State of New York.

Section 113.         NON-BUSINESS DAY.

           Unless otherwise stated with respect to Securities of any series,  in
any case where any Interest Payment Date,  Redemption Date or Stated Maturity of
a Security of any particular  series shall not be a Business Day at any Place of
Payment with respect to Securities  of that series,  then  (notwithstanding  any
other  provision of this Indenture or of the  Securities or coupons)  payment of
principal of (and premium,  if any) and  interest,  if any, with respect to such
Security need not be made at such Place of Payment on such date, but may be made

           No  recourse  shall be had for the payment of the  principal  of (and
premium,  if any),  or the  interest,  if any, on any  Security or coupon of any
series,  or for any claim based  thereon,  or upon any  obligation,  covenant or
agreement of this Indenture, against any incorporator,  stockholder,  officer or
director,  as such, past,  present or future, of the Company or of any successor
corporation,  either directly or indirectly through the Company or any successor
corporation, whether by virtue of any constitution, statute or rule of law or by
the  enforcement of any assessment of penalty or otherwise;  it being  expressly
agreed and understood  that this Indenture and all the Securities and coupons of
each series are solely  corporate  obligations,  and that no personal  liability
whatever  shall  attach to, or is incurred  by, any  incorporator,  stockholder,
officer or director, past, present or future, of the Company or of any successor
corporation,  either directly or indirectly through the Company or any successor
corporation,  because of the incurring of the indebtedness  hereby authorized or
under or by reason of any of the obligations,  covenants or agreements contained
in this Indenture or in any of the Securities or coupons of any series, or to be
implied  herefrom or therefrom;  and that all such personal  liability is hereby
expressly   released  and  waived  as  a  condition  of,  and  as  part  of  the
consideration  for,  the  execution  of this  Indenture  and the issuance of the
Securities and coupons of each series.

           Subject to Section  311,  each  reference to any currency or currency
unit in any  Security,  or in the Board  Resolution  or  supplemental  indenture
relating thereto,  shall mean only the referenced  currency or currency unit and
no other currency or currency unit.

           The Trustee shall  segregate  moneys,  funds and accounts held by the
Trustee in one currency or currency unit from any moneys, funds or accounts held
in any other currencies or currency units,  notwithstanding any provision herein
which would otherwise permit the Trustee to commingle such amounts.

           Whenever any action or Act is to be taken hereunder by the Holders of
Securities denominated in a Foreign Currency or currency unit, then for purposes
of  determining  the principal  amount of Securities  held by such Holders,  the
aggregate  principal amount of the Securities  denominated in a Foreign Currency

Section 203.         SECURITIES IN GLOBAL FORM.

           If any Security of a series is issuable in global form, such Security
may  provide  that it  shall  represent  the  aggregate  amount  of  Outstanding
Securities  from time to time  endorsed  thereon and may also  provide  that the
aggregate amount of Outstanding  Securities represented thereby may from time to

shall be in writing but need not comply with Section 102.

           Global  Securities may be issued in either  registered or bearer form
and in either temporary or permanent form.

     All Securities of any particular series and the coupons appertaining to any
Bearer  Securities of such series shall be substantially  identical except as to
denomination,  rate of  interest,  Stated  Maturity  and  the  date  from  which
interest,  if any,  shall accrue,  and except as may otherwise be provided in or
pursuant to such Board  Resolutions and set forth in such Officer's  Certificate

                                       19

<PAGE>



     Indenture relating to the authentication and delivery of Securities in such
     forms have been complied with; and

          (3) An Opinion of  Counsel  stating  that  Securities  in such  forms,
     together  with any coupons  appertaining  thereto,  when (a)  completed  by
     appropriate  insertions  and executed and  delivered by the Company to such
     Trustee  for   authentication  in  accordance  with  this  Indenture,   (b)
     authenticated  and  delivered  by such  Trustee  in  accordance  with  this
     Indenture  within  the  authorization  as  to  aggregate  principal  amount
     established from time to time by the Board of Directors of the Company, and
     (c) sold in the manner  specified in such  Opinion of Counsel,  will be the
     legal, valid and binding obligations of the Company, subject to the effects
     of   applicable   bankruptcy,   reorganization,    fraudulent   conveyance,
     moratorium,   insolvency  and  other  similar  laws   generally   affecting
     creditors' rights, to general equitable principles,  to an implied covenant
     of good faith and fair  dealing  and to such other  qualifications  as such
     counsel shall  conclude do not  materially  affect the rights of Holders of
     such Securities.

Section 302.         DENOMINATIONS AND CURRENCIES.

           Unless otherwise provided with respect to any series of Securities as
contemplated  by Section 301,  any  Registered  Securities  of a series shall be
issuable in denominations of $1,000 and any integral multiple  thereof,  and any
Bearer  Securities of a series shall be issuable in the  denomination of $5,000,
or the  equivalent  amounts  thereof in the case of  Registered  Securities  and
Bearer  Securities  denominated in a Foreign Currency or currency unit.

Section 303. EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

           The Securities and any related coupons shall be executed on behalf of
the Company by its Chairman of the Board,  a Vice Chairman of the Board,  or its
President or one of its Vice  Presidents.  The  Securities  shall be so executed
under the corporate  seal of the Company  reproduced  thereon and attested to by
its Secretary or any one of its Assistant  Secretaries.  The signature of any of
these officers on the Securities may be manual or facsimile.

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

           At any time and from time to time after the execution and delivery of
this Indenture,  the Company may deliver  Securities of any series together with
any coupons appertaining thereto, executed by the Company to the Trustee for the
Securities of such series for authentication,  together with a Company Order for
the  authentication  and  delivery  of such  Securities,  and such  Trustee,  in
accordance  with  the  Company  Order,   shall  authenticate  and  deliver  such
Securities;  PROVIDED, HOWEVER, that, during the "restricted period" (as defined
in Section 1.163-5(c)(2)(i)(D)(7) of the United States Treasury Regulations), no
Bearer  Security  shall be mailed or otherwise  delivered to any location in the
United States;  and PROVIDED,  FURTHER,  that a Bearer Security may be delivered
outside the United States in connection  with its original  issuance only if the
Person  entitled to receive  such Bearer  Security  shall have  furnished to the
Trustee for the  Securities  of such series a certificate  substantially  in the
form  set  forth  in  Exhibit  A to this  Indenture.  If any  Security  shall be
represented by a permanent Global  Security,  then, for purposes of this Section
and Section  304, the notation of a  beneficial  owner's  interest  therein upon
original  issuance of such Security or upon exchange of a portion of a temporary
Global  Security shall be deemed to be delivery in connection  with the original
issuance of such beneficial  owner's interest in such permanent Global Security.
Except as permitted by Section 306 or 307, the Trustee for the  Securities  of a
series  shall not  authenticate  and  deliver  any  Bearer  Security  unless all
appurtenant coupons for interest then matured other than matured coupons in

                                       20

<PAGE>



default  have been  detached and  cancelled.  If all the  Securities  of any one
series are not to be issued at one time and if a Board  Resolution  relating  to
such  Securities  shall so permit,  such Company Order may set forth  procedures
acceptable  to the  Trustee  for the  issuance  of such  Securities,  including,
without  limitation,  procedures with respect to interest rate, Stated Maturity,
date of issuance and date from which interest, if any, shall accrue.

           Notwithstanding any contrary provision herein, if all Securities of a
series are not to be originally issued at one time, it shall not be necessary to
deliver  the Board  Resolution,  Officers'  Certificate  and  Opinion of Counsel
otherwise  required  pursuant to Sections 102 and 301 at or prior to the time of
authentication  of each Security of such series if such  documents are delivered
at or prior to the  authentication  upon original issuance of the first Security
of such series to be issued.

           Each   Registered   Security   shall  be   dated   the  date  of  its
authentication,  and, unless otherwise specified as contemplated by Section 301,
each Bearer  Security shall be dated as of the date of original  issuance of the
first Security of such series to be issued.

           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 herein manually  executed by the Trustee for such Security
or on its behalf pursuant to Section 614, and such certificate upon any Security
shall be conclusive evidence, and the only evidence, that such Security has been
duly authenticated and delivered hereunder.

           In  case  any  Securities  shall  have  been  authenticated,  but not
delivered,  by the Trustee or the  Authenticating  Agent for such series then in
office, any successor by merger, conversion or consolidation to such Trustee, or
any  successor  Authenticating  Agent,  as the  case  may  be,  may  adopt  such
authentication  and deliver the Securities so authenticated with the same effect
as if such  successor  Trustee  or  successor  Authenticating  Agent had  itself
authenticated such Securities.

           Each  Depositary  designated  pursuant  to  Section  301 for a Global
Security in  registered  form must,  at the time of its  designation  and at all
times while it serves as Depositary,  be a clearing agency  registered under the
Exchange  Act and any other  applicable  statute  or  regulation.

Section  304. TEMPORARY SECURITIES AND EXCHANGE OF SECURITIES.

           Pending the  preparation  of definitive  Securities of any particular
series,  the Company may  execute,  and upon  Company  Order the Trustee for the
Securities  of  such  series  shall  authenticate  and  deliver,  in the  manner
specified in Section 303, temporary Securities which are printed,  lithographed,
typewritten,  photocopied or otherwise produced, in any denomination,  with like
terms and  conditions  as the  definitive  Securities  of like series in lieu of
which they are issued in registered form or, if authorized,  in bearer form with
one or more coupons or without coupons,  and with such  appropriate  insertions,
omissions,  substitutions  and other  variations as the officers  executing such
Securities may determine,  as evidenced by their  execution of such  Securities.
Any such temporary  Securities may be in global form,  representing  such of the
Outstanding Securities of such series as shall be specified therein.

           Except in the case of  temporary  Securities  in global  form  (which
shall be exchanged  only in  accordance  with the  provisions  of the  following
paragraphs),  if temporary  Securities of any particular series are issued,  the
Company will cause  definitive  Securities of that series to be prepared without
unreasonable  delay.  After the preparation of such definitive  Securities,  the
temporary  Securities of such series shall be  exchangeable  for such definitive
Securities and of a like Stated Maturity and with like terms and provisions upon
surrender  of the  temporary  Securities  of  such  series,  together  with  all
unmatured and matured coupons in default, if any, at

                                       21

<PAGE>



the  office or agency of the  Company  in a Place of  Payment  for that  series,
without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities of any particular series, the Company shall execute and (in
accordance with a Company Order delivered at or prior to the  authentication  of
the first definitive  Security of such series) the Trustee for the Securities of
such  series or the Global  Exchange  Agent  shall  authenticate  and deliver in
exchange therefor a like principal amount of definitive Securities of authorized
denominations  of the same  series and of a like Stated  Maturity  and with like
terms and provisions;  PROVIDED, HOWEVER, unless otherwise specified pursuant to
Section 301, no definitive  Bearer Security 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 Section 303.  Until  exchanged as
hereinabove  provided,  the  temporary  Securities  of any  series  shall in all
respects be entitled to the same  benefits  under this  Indenture as  definitive
Securities of the same series and with like terms and  conditions,  except as to
payment of interest, if any, authenticated and delivered hereunder.

           Any  temporary  Global  Security and any  permanent  Global  Security
shall,   unless  otherwise  provided  therein,  be  delivered  to  a  Depositary
designated pursuant to Section 301.

           Without  unnecessary  delay but in any event not later  than the date
specified in or determined  pursuant to the terms of any such  temporary  Global
Security (the  "Exchange  Date"),  the  Securities  represented by any temporary
Global  Security  of a series  of  Securities  issuable  in  bearer  form may be
exchanged for definitive Securities (subject to the second succeeding paragraph)
or  Securities to be  represented  thereafter  by one or more  permanent  Global
Securities,  without  interest  coupons.  On or after  the  Exchange  Date  such
temporary  Global Security shall be surrendered by the Depositary to the Trustee
for such  Security,  as the  Company's  agent  for such  purpose,  or the  agent
appointed  by the Company  pursuant to Section 301 to effect the exchange of the
temporary  Global  Security for  definitive  Securities  (the  "Global  Exchange
Agent"), and following such surrender, such Trustee or the Global Exchange Agent
(as  authorized by the Trustee as an  Authenticating  Agent  pursuant to Section
614) shall (1) endorse the temporary Global Security to reflect the reduction of
its principal  amount by an equal aggregate  principal  amount of such Security,
(2) endorse the applicable  permanent  Global  Security,  if any, to reflect the
initial amount, or an increase in the amount of Securities  represented thereby,
(3) manually  authenticate  such definitive  Securities or such permanent Global
Security,  as the  case  may be,  (4)  subject  to  Section  303,  deliver  such
definitive Securities to the Holder thereof or, as the case may be, deliver such
permanent Global Security to the Depositary to be held outside the United States
for the accounts of Euro-clear  and  Clearstream,  for credit to the  respective
accounts  at  Euro-clear  and  Clearstream,  designated  by or on  behalf of the
beneficial  owners of such  Securities  (or to such other  accounts  as they may
direct) and (5) redeliver  such  temporary  Global  Security to the  Depositary,
unless such  temporary  Global  Security shall have been cancelled in accordance
with Section 309 hereof; PROVIDED,  HOWEVER, that, unless otherwise specified in
such temporary Global Security,  upon such presentation by the Depositary,  such
temporary  Global  Security  shall be  accompanied  by a  certificate  dated the
Exchange Date or a subsequent date and signed by Euro-clear as to the portion of
such  temporary  Global  Security  held for its account then to be exchanged for
definitive  Securities or one or more permanent Global  Securities,  as the case
may be, and a  certificate  dated the  Exchange  Date or a  subsequent  date and
signed by Clearstream,  as to the portion of such temporary Global Security held
for its account then to be exchanged  for  definitive  Securities or one or more
permanent Global Securities,  as the case may be, each substantially in the form
set forth in Exhibit B to this Indenture.  Each certificate substantially in the
form of Exhibit B hereto of Euro-clear or Clearstream, as the case may be, shall
be based on  certificates  of the  account  holders  listed  in the  records  of
Euro-clear or  Clearstream,  as the case may be, as being entitled to all or any
portion of the  applicable  temporary  Global  Security.  An  account  holder of
Euro-clear or  Clearstream,  as the case may be, desiring to effect the exchange
of interest  in a  temporary  Global  Security  for an  interest  in  definitive
Securities or one or more permanent Global Securities shall instruct  Euro-clear
or  Clearstream,  as the case may be, to request such exchange on its behalf and
shall deliver to Euro-clear or Clearstream, as the case

                                                             22

may be, a certificate substantially in the form of Exhibit A hereto and dated no
earlier than 15 days prior to the Exchange Date.  Until so exchanged,  temporary
Global  Securities  shall in all respects be entitled to the same benefits under
this Indenture as definitive  Securities and permanent Global  Securities of the
same series  authenticated  and delivered  hereunder,  except as provided in the
fourth succeeding paragraph.

           The  delivery to the Trustee for the  Securities  of the  appropriate
series  or the  Global  Exchange  Agent  by  Euro-clear  or  Clearstream  of any
certificate  substantially in the form of Exhibit B hereto may be relied upon by
the Company and such Trustee or the Global Exchange Agent as conclusive evidence
that a corresponding  certificate or certificates  has or have been delivered to
Euro-clear or to Clearstream,  as the case may be, pursuant to the terms of this
Indenture.

           On or prior to the Exchange  Date,  the Company  shall deliver to the
Trustee for the  Securities  of the  appropriate  series or the Global  Exchange
Agent definitive Securities in aggregate principal amount equal to the principal
amount of such temporary Global Security, executed by the Company in the case of
the Securities. At any time, on or after the Exchange Date, upon 30 days' notice
to the  Trustee  for the  Securities  of the  appropriate  series or the  Global
Exchange Agent by Euro-clear or  Clearstream,  as the case may be, acting at the
request of or on behalf of the  beneficial  owner,  a Security  represented by a
temporary Global Security or a permanent  Global  Security,  as the case may be,
may be  exchanged,  in  whole  or from  time to time  in  part,  for  definitive
Securities  without  charge and such Trustee or the Global  Exchange Agent shall
authenticate and deliver,  in exchange for each portion of such temporary Global
Security or such permanent Global Security,  an equal aggregate principal amount
of definitive Securities of the same series of authorized denominations and with
like terms and  provisions as the portion of such temporary  Global  Security or
such permanent Global Security to be exchanged,  which, unless the Securities of
the  series  are  not  issuable  both as  Bearer  Securities  and as  Registered
Securities,  as  contemplated  by  Section  301,  shall be in the form of Bearer
Securities or Registered  Securities,  or any combination  thereof,  as shall be
specified by the beneficial owner thereof;  PROVIDED,  HOWEVER,  that definitive
Bearer  Securities shall be delivered in exchange for a portion of the temporary
Global  Security or the permanent  Global  Security only in compliance  with the
requirements of the second preceding paragraph. On or prior to the thirtieth day
following receipt by the Trustee for the Securities of the appropriate series or
the Global Exchange Agent of such notice with respect to a Security, or, if such
day is not a Business  Day, the next  succeeding  Business  Day,  the  temporary
Global Security or the permanent Global  Security,  as the case may be, shall be
surrendered by the Depositary to such Trustee,  as the Company's  agent for such
purpose,  or the Global Exchange Agent to be exchanged in whole, or from time to
time in part, for definitive Securities without charge following such surrender,
upon the  request of  Euro-clear  or  Clearstream,  as the case may be, and such
Trustee or the Global Exchange Agent shall (1) endorse the applicable  temporary
Global Security or the permanent Global Security to reflect the reduction of its
principal  amount by the aggregate  principal  amount of such  Security,  (2) in
accordance  with  procedures  acceptable  to the Trustee cause the terms of such
Security  and  coupons,  if any,  to be entered on a  definitive  Security,  (3)
manually  authenticate such definitive  Security and (4) if a Bearer Security is
to be delivered,  deliver such definitive  Security outside the United States to
Euro-clear  or  Clearstream,  as  the  case  may  be,  for or on  behalf  of the
beneficial  owner thereof,  in exchange for a portion of such  permanent  Global
Security.

           Unless  otherwise  specified  in such  temporary  Global  Security or
permanent Global Security, any such exchange shall be made free of charge to the
beneficial  owners  of  such  temporary  Global  Security  or  permanent  Global
Security,  except that a Person  receiving  definitive  Securities must bear the
cost of insurance,  postage,  transportation and the like in the event that such
Person does not take  delivery of such  definitive  Securities  in person at the
offices of Euro-clear or Clearstream. Definitive Securities in bearer form to be
delivered in exchange for

any portion of a temporary  Global Security or a permanent Global Security shall
be delivered only outside the United States.

           Until exchanged in full as hereinabove provided, any temporary Global
Security or permanent  Global  Security shall in all respects be entitled to the
same benefits under this  Indenture as definitive  Securities of the same series
and with like terms and  conditions,  except as to payment of interest,  if any,
authenticated   and  delivered   hereunder.   Unless   otherwise   specified  as
contemplated by Section 301,  interest payable on such temporary Global Security
on an Interest  Payment Date for  Securities  of such series shall be payable to
Euro-clear  and  Clearstream  on such  Interest  Payment  Date upon  delivery by
Euro-clear and  Clearstream to the Trustee for the Securities of the appropriate
series or the Global  Exchange  Agent in the case of payment  of  interest  on a
temporary  Global  Security with respect to an Interest  Payment Date  occurring
prior  to  the  applicable  Exchange  Date  of  a  certificate  or  certificates
substantially  in the form set forth in Exhibit C to this Indenture,  for credit
without  further  interest  on or  after  such  Interest  Payment  Date  to  the
respective  accounts of the Persons who are the beneficial owners of such Global
Security on such  Interest  Payment Date and who have, in the case of payment of
interest on a temporary Global Security with respect to an Interest Payment Date
occurring prior to the applicable Exchange Date, each delivered to Euro-clear or
Clearstream,  as the case may be, a  certificate  substantially  in the form set
forth in Exhibit D to this Indenture.

           Any definitive  Bearer  Security  authenticated  and delivered by the
Trustee for the  Securities  of the  appropriate  series or the Global  Exchange
Agent in exchange  for a portion of a temporary  Global  Security or a permanent
Global Security shall not bear a coupon for any interest which shall theretofore
have been duly paid by such  Trustee  to  Euro-clear  or  Clearstream  or by the
Company to such Trustee in accordance with the provisions of this Section 304.

           With respect to Exhibits A, B, C and D to this Indenture, the Company
may, in its  discretion  and if  required or  desirable  under  applicable  law,
substitute one or more other forms of such exhibits for such exhibits, eliminate
the requirement  that any or all  certificates  be provided,  or change the time
that any  certificate  may be required,  PROVIDED that such  substitute  form or
forms or notice of elimination or change of such certification  requirement have
theretofore  been delivered to the Trustee with a Company  Request and such form
or forms, elimination or change is reasonably acceptable to the Trustee.

Section 305.         REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

           The Company shall cause to be kept at the  Corporate  Trust Office of
the  Trustee  for the  Securities  of  each  series  a  register  (the  register
maintained  in such office being herein  sometimes  referred to as the "Security
Register") in which, subject to such reasonable regulations as it may prescribe,
the Company shall provide for the  registration of Registered  Securities and of
transfers  of  Registered  Securities.  The Trustee for the  Securities  of each
series is hereby  initially  appointed  "Security  Registrar" for the purpose of
registering Registered Securities and transfers of Registered Securities of such
series as herein provided.

           Upon  surrender  for  registration  of  transfer  of  any  Registered
Security  of any  particular  series at the office or agency of the Company in a
Place of Payment for that series, the Company shall execute, and the Trustee for
the Securities of each series shall authenticate and deliver, in the name of the
designated  transferee or transferees,  one or more new Registered Securities of
any authorized denominations, and of a like Stated Maturity and of a like series
and aggregate principal amount and with like terms and conditions.

           Except as set forth  below,  at the option of the Holder,  Registered
Securities  of any  particular  series  may be  exchanged  for other  Registered
Securities of any authorized denominations, and of a like Stated Maturity and of
a like series and aggregate  principal amount and with like terms and conditions
upon surrender of the Registered Securities to be exchanged

                                                             24

<PAGE>



at such  office or  agency.  Whenever  any  Securities  are so  surrendered  for
exchange,  the Company shall execute,  and the Trustee for such Securities shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.  Except as  otherwise  specified  pursuant to Section  301,
Registered Securities may not be exchanged for Bearer Securities.

           Notwithstanding  any other  provision of this Section or Section 304,
unless and until it is exchanged in whole or in part for  Registered  Securities
in  definitive  form,  a Global  Security  representing  all or a portion of the
Registered  Securities of a series may not be  transferred  except as a whole by
the Depositary  for such series to a nominee of such  Depositary or by a nominee
of such  Depositary to such  Depositary or another nominee of such Depositary or
by such Depositary or any such nominee to a successor Depositary for such series
or a nominee of such successor Depositary.

           At the option of the Holder,  Bearer  Securities of any series may be
exchanged  for  Registered  Securities  of the  same  series  of any  authorized
denominations  and of a like aggregate  principal amount and with like terms and
provisions upon surrender of the Bearer Securities to be exchanged at any office
or  agency  of the  Company  in a Place of  Payment  for that  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 (or to the Trustee for the Security in case of matured coupons in
default)  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 such  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  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 1002,
interest  represented  by coupons  shall be payable only upon  presentation  and
surrender  of those  coupons at an office or agency of the Company in a Place of
Payment for that 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 in exchange  for a  Registered  Security of the same series and
with like terms and  conditions  after the close of  business  at such office or
agency on or after  (i) any  Regular  Record  Date and  before  the  opening  of
business at such office or agency on the relevant Interest Payment Date, or (ii)
any  Special  Record  Date and before the  opening of business at such office or
agency on the related  proposed  date for payment of  Defaulted  Interest,  such
Bearer  Security  shall be  surrendered  without  the  coupon  relating  to such
Interest  Payment Date or proposed date for 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,  will 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 will be
payable  only to the  Holder  of such  coupon  when due in  accordance  with the
provisions of this Indenture.

           Whenever any Securities are so surrendered for exchange,  the Company
shall  execute,  and the  Trustee for such  Securities  shall  authenticate  and
deliver,  the  Securities  which the Holder  making the  exchange is entitled to
receive.

           If  at  any  time  the  Depositary  for  Securities  of a  series  in
registered  form notifies the Company that it is unwilling or unable to continue
as Depositary for the Securities of such series or if at any time the Depositary
for the Securities of such series shall no longer be eligible under Section 303,
the Company shall appoint a successor  Depositary with respect to the Securities
for such series. If (i) a successor Depositary for the Securities of such series
is not appointed by the Company  within 90 days after the Company  receives such
notice or becomes aware of such

                                                             25

<PAGE>



ineligibility,  (ii) the Company  delivers to the Trustee for Securities of such
series in registered  form a Company  Order stating that the  Securities of such
series shall be  exchangeable,  or (iii) an Event of Default  under  Section 501
hereof has occurred and is  continuing  with respect to the  Securities  of such
series,  the  Company's  election  pursuant  to  Section  301 shall no longer be
effective  with respect to the  Securities  for such series and the Company will
execute, and the Trustee, upon receipt of a Company Order for the authentication
and delivery of definitive  Securities  of such series,  will  authenticate  and
deliver  Securities of such series in definitive form in an aggregate  principal
amount  equal to the  principal  amount of the  Global  Security  or  Securities
representing such series in exchange for such Global Security or Securities.

           The Company may at any time and in its sole discretion determine that
the Registered Securities of any series issued in the form of one or more Global
Securities shall no longer be represented by such Global Security or Securities.
In such event the Company  will  execute,  and the  Trustee,  upon  receipt of a
Company  Order for the  authentication  and  delivery of  definitive  Registered
Securities of such series, will authenticate and deliver,  Registered Securities
of such series in definitive form and in an aggregate  principal amount equal to
the  principal  amount of the Global  Security or Securities  representing  such
series in exchange for such Global Security or Securities.

           If specified by the Company pursuant to Section 301 with respect to a
series of Securities  in  registered  form,  the  Depositary  for such series of
Securities  may  surrender a Global  Security for such series of  Securities  in
exchange  in whole or in part for  Securities  of such  series of like tenor and
terms and in definitive  form on such terms as are acceptable to the Company and
such  Depositary.  Thereupon  the Company shall  execute,  and the Trustee shall
authenticate and deliver,  without service charge,  (i) to each Person specified
by such  Depositary a new  Security or  Securities  of the same series,  of like
tenor and terms and of any authorized  denomination  as requested by such Person
in  aggregate  principal  amount  equal to and in  exchange  for  such  Person's
beneficial  interest in the Global  Security;  and (ii) to such Depositary a new
Global  Security  of like  tenor and terms  and in a  denomination  equal to the
difference,  if any,  between the  principal  amount of the  surrendered  Global
Security and the aggregate  principal amount of Securities  delivered to Holders
thereof.

           Upon the exchange of a Global  Security for  Securities in definitive
form,  such  Global  Security  shall be  cancelled  by the  Trustee.  Registered
Securities  issued in exchange  for a Global  Security  pursuant to this Section
shall be registered in such names and in such  authorized  denominations  as the
Depositary for such Global Security, pursuant to instructions from its direct or
indirect  participants or otherwise,  shall instruct the Trustee in writing. The
Trustee  shall  deliver such  Registered  Security to the persons in whose names
such Securities are so registered.

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

           Every Security  presented or surrendered for registration of transfer
or  exchange  shall (if so  required  by the  Company  or the  Trustee  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
series duly executed,  by the Holder thereof or his attorney duly  authorized in
writing.

           No service charge shall be made for any  registration  of transfer or
exchange of Securities,  but the Company may require payment of a sum sufficient
to cover any tax or other governmental  charge that may be imposed in connection
with any  registration  of  transfer  or  exchange  of  Securities,  other  than
exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

                                       26

<PAGE>



           The Company shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of  redemption  of
Securities of that series selected for redemption  under Section 1104 and ending
at the close of business on (A) if Securities of the series are issuable only as
Registered  Securities,  the  day  of the  mailing  of the  relevant  notice  of
redemption  and  (B)  if  Securities  of  the  series  are  issuable  as  Bearer
Securities,  the  day  of  the  first  publication  of the  relevant  notice  of
redemption  or, if  Securities  of the series are also  issuable  as  Registered
Securities and there is no  publication,  the mailing of the relevant  notice of
redemption,  or (ii) to register  the  transfer of or  exchange  any  Registered
Security so selected for redemption as a whole or in part, except the unredeemed
portion of any Security  being redeemed in part, or (iii) to exchange any Bearer
Security so selected for  redemption  except that such a Bearer  Security may be
exchanged  for a  Registered  Security of that series and like tenor;  PROVIDED,
HOWEVER,  that such Registered Security shall be simultaneously  surrendered for
redemption.

           Furthermore, notwithstanding any other provision of this Section 305,
the Company will not be required to exchange any  Securities  if, as a result of
the exchange,  the Company would suffer  adverse  consequences  under any United
States law or regulation.

Section 306.  MUTILATED,  DESTROYED,  LOST AND STOLEN SECURITIES AND COUPONS.

           If (i) any mutilated  Security or a Security with a mutilated  coupon
appertaining  thereto is  surrendered  to the Trustee  for such  Security or the
Company and the Trustee for a Security receive evidence to their satisfaction of
the  destruction,  loss or theft of any  Security  or coupon  and (ii)  there is
delivered to the Company and such  Trustee 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 such Trustee that such Security
or coupon has been acquired by a bona fide purchaser,  the Company shall execute
and upon its request such Trustee shall authenticate and deliver, in lieu of any
such  destroyed,  lost or stolen  Security  or in  exchange  for such  mutilated
Security, or in exchange for the Security to which a mutilated,  destroyed, lost
or  stolen  coupon  appertains  (with all  appurtenant  coupons  not  mutilated,
destroyed,  lost or  stolen) a new  Security  of the same  series  and in a like
principal  amount  and of a  like  Stated  Maturity  and  with  like  terms  and
conditions, and bearing a number not contemporaneously  outstanding with coupons
corresponding to the coupons, if any, appertaining to such mutilated, destroyed,
lost or stolen Security or to the Security to which such  mutilated,  destroyed,
lost or stolen coupon appertains.

           In case any such  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
(without surrender thereof except in the case of a mutilated Security or coupon)
if the  applicant  for such payment shall furnish to the Company and the Trustee
for such  Security such security or indemnity as may be required by them to save
each of them  harmless,  and in case of  destruction,  loss or  theft,  evidence
satisfactory to the Company and such Trustee and any agent of any of them of the
destruction, loss or theft of such Security and the ownership thereof; PROVIDED,
HOWEVER,  that the principal of (and premium,  if any) and interest,  if any, on
Bearer  Securities  shall,  except as  otherwise  provided in Section  1002,  be
payable  only at an office or agency  located  outside  the United  States  and,
unless  otherwise  specified  as  contemplated  by Section  301, any interest on
Bearer  Securities shall be payable only upon  presentation and surrender of the
coupons appertaining thereto.

           Upon the issuance of any new Security under this Section, 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  all fees and  expenses of the  Trustee for such  Security)
connected therewith.

                                                             27

<PAGE>



           Every new Security of any series,  with its coupons,  if any,  issued
pursuant to this Section in lieu of any destroyed, lost or stolen Security or in
exchange for any  mutilated  Security,  or in exchange for a Security to which a
mutilated,  destroyed,  lost or stolen  coupon  appertains  shall  constitute an
original  additional  contractual  obligation of the Company  whether or not the
destroyed,  lost or stolen  Security and its coupons,  if any, or the destroyed,
lost or stolen coupon shall be at any time enforceable by anyone,  and each such
new  Security  shall be at any time  enforceable  by  anyone,  and each such new
Security  shall be entitled to all the  benefits of this  Indenture  equally and
proportionately  with any and all other  Securities of the same series and their
coupons, if any, duly issued hereunder.

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

Section 307.         PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

           Interest  on  any  Registered  Security  which  is  payable,  and  is
punctually paid or duly provided for, on any Interest  Payment Date shall, if so
provided in such Security, be paid to the Person in whose name that Security (or
one or more  Predecessor  Securities)  is registered at the close of business on
the Regular Record Date for such interest payment.

           Unless  otherwise  provided  with  respect to the  Securities  of any
series, payment of interest may be made at the Corporate Trust Office or, at the
option of the Company (i) in the case of Registered  Securities,  may be made by
check mailed to the address of the Person entitled thereto as such address shall
appear in the Security Register, or (ii) in the case of Bearer Securities,  upon
presentation and surrender of the appropriate coupon appertaining  thereto or by
transfer to an account  maintained by the payee with a bank located  outside the
United States.  Notwithstanding the foregoing, a Holder of $1,000,000 or more in
aggregate  principal  amount of  Securities  of any series in  definitive  form,
whether  having  identical or different  terms and  provisions,  having the same
Interest  Payment  Dates  will,  at the option of the  Company,  be  entitled to
receive  interest  payments,  other  than  at  Maturity,  by  wire  transfer  of
immediately  available funds if appropriate wire transfer instructions have been
received in writing by the Trustee for the Securities of such series at least 15
days  prior to the  applicable  Interest  Payment  Date.  Any wire  instructions
received by the Trustee for the Securities of such series shall remain in effect
until revoked by the Holder.

           Unless  otherwise  provided or  contemplated  by Section  301,  every
permanent  Global  Security will provide that interest,  if any,  payable on any
Interest  Payment Date will be paid to each of Euro-clear and  Clearstream  with
respect to that portion of such permanent  Global  Security held for its account
by the Depositary. Each of Euro-clear and Clearstream will in such circumstances
credit the interest  received by it in respect of such permanent Global Security
to the accounts of the beneficial owners thereof.

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

                     (1) The Company may elect to make payment of any  Defaulted
           Interest to the Persons in whose names the  Registered  Securities of
           that  series  (or  their  respective   Predecessor   Securities)  are
           registered at the close of business on a Special  Record Date for the
           payment  of such  Defaulted  Interest,  which  shall  be fixed in the
           following  manner.  The  Company  shall  notify the  Trustee  for the
           Registered  Securities  of such  series in  writing  of the amount of
           Defaulted Interest proposed to be paid on each Registered

                                       28

<PAGE>



           Security of that series and the date of the proposed payment,  and at
           the same time the Company  shall  deposit with such Trustee an amount
           of money in the currency or currency unit in which the  Securities of
           such series are payable  (except as otherwise  specified  pursuant to
           Section 301 for the  Securities of such series and except as provided
           in  Sections  311(b)  and  311(d)),  equal  to the  aggregate  amount
           proposed  to be paid in respect of such  Defaulted  Interest or shall
           make arrangements satisfactory to such Trustee for such deposit prior
           to the date of the proposed payment,  such money when deposited to be
           held in  trust  for  the  benefit  of the  Persons  entitled  to such
           Defaulted Interest as in this clause provided. Thereupon such Trustee
           shall fix a Special  Record  Date for the  payment of such  Defaulted
           Interest  which  shall  not be more than 15 days and not less than 10
           days prior to the date of the  proposed  payment and not less than 10
           days after the receipt by such  Trustee of the notice of the proposed
           payment.  Such  Trustee  shall  promptly  notify the  Company of such
           Special  Record  Date  and,  in the  name and at the  expense  of the
           Company, shall cause notice of the proposed payment of such Defaulted
           Interest  and  the  Special   Record  Date  therefor  to  be  mailed,
           first-class postage prepaid, to each Holder of Registered  Securities
           of that series at his address as it appears in the Security  Register
           not less than 10 days prior to such Special Record Date. Such 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 a
           newspaper  published  in the English  language,  customarily  on each
           Business Day and of general  circulation  in New York,  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 Persons in whose names the Registered Securities
           of that  series  (or their  respective  Predecessor  Securities)  are
           registered on such Special Record Date and shall no longer be payable
           pursuant to the following clause (2).

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

           Subject to the foregoing  provisions of this Section and Section 305,
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.

           Prior to due presentment of a Registered Security for registration of
transfer,  the  Company,  the  Trustee  for such  Security  and any agent of the
Company or such Trustee may treat the Person in whose name any such  Security is
registered as the owner of such Security for the purpose of receiving payment of
principal of (and  premium,  if any) and (subject to Section 307)  interest,  if
any, on such Security and for all other purposes whatsoever, whether or not such
Security be overdue,  and none of the Company,  such Trustee or any agent of the
Company or such Trustee shall be affected by notice to the contrary.

           Title to any Bearer  Security  and any coupons  appertaining  thereto
shall pass by delivery. The Company, the Trustee for such Security and any agent
of the Company or such  Trustee may treat the bearer of any Bearer  Security and
the bearer of any coupon as the absolute owner of such Bearer Security or coupon
for the purpose of receiving  payment  thereof or on account thereof and for all

overdue,  and none of the  Company,  such Trustee or any agent of the Company or
such Trustee shall be affected by notice to the contrary.

           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 309.         CANCELLATION.

           All  Securities  and coupons  surrendered  for  payment,  redemption,
registration  of transfer or  exchange,  or  delivered  in  satisfaction  of any
sinking fund payment, shall, if surrendered to any Person other than the Trustee
for such Securities, be delivered to such Trustee and, in the case of Registered
Securities and matured  coupons,  shall be promptly  cancelled by it. All Bearer
Securities and unmatured coupons so delivered to the Trustee for such Securities
shall be cancelled by such  Trustee.  The Company may at any time deliver to the
Trustee for Securities of a series for  cancellation  any Securities  previously
authenticated and delivered hereunder which the Company may have acquired in any
manner  whatsoever,  and all Securities so delivered shall be promptly cancelled
by such Trustee.  Notwithstanding  any other  provision of this Indenture to the
contrary,  in the case of a series,  all the  Securities  of which are not to be
originally  issued at one time, a Security of such series shall not be deemed to
have  been  Outstanding  at any  time  hereunder  if and  to  the  extent  that,
subsequent  to  the  authentication  and  delivery  thereof,  such  Security  is
delivered to the Trustee for such  Security for  cancellation  by the Company or
any agent  thereof  upon the failure of the original  purchaser  thereof to make
payment therefor against delivery thereof, and any Security so delivered to such
Trustee shall be promptly  cancelled by it. 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  this  Indenture.  All  cancelled
Securities and coupons held by the Trustee for such Securities shall be disposed
of by such Trustee in accordance with its standard  procedures and a certificate
of disposition  evidencing  such  disposition of Securities and coupons shall be
provided to the Company by such  Trustee.  In the case of any  temporary  Global
Security, which shall be disposed of if the entire aggregate principal amount of
the  Securities  represented  thereby has been  exchanged,  the  certificate  of
disposition  shall state that all certificates  required pursuant to Section 304
hereof,  substantially  in the form of  Exhibit B hereto  (or in the form of any
substitute  exhibit as provided in the last  paragraph  of Section  304),  to be
given by Euro-clear or Clearstream,  have been duly presented to the Trustee for
such  Securities  by Euro-clear or  Clearstream,  as the case may be.  Permanent
Global  Securities  shall  not be  disposed  of  until  exchanged  in  full  for
definitive Securities or until payment thereon is made in full.

Section 310.         COMPUTATION OF INTEREST.

           Except as  otherwise  specified  as  contemplated  by Section 301 for
Securities of any particular  series,  interest on the Securities of each series
shall be computed on the basis of a 360-day year of twelve 30-day months.

Section 311.         CURRENCY AND MANNER OF PAYMENTS IN RESPECT OF SECURITIES.

          Unless otherwise specified in accordance with Section 301 with respect
     to any series of Securities, the following provisions shall apply:

           (a) Except as provided in paragraphs (b) and (d) below, the principal
of, premium,  if any, and interest on Securities of any series  denominated in a
Foreign  Currency  or  currency  unit will be payable by the  Company in Dollars
based on the equivalent of that Foreign Currency or currency unit converted into
Dollars in the manner described in paragraph (c) below.

                                       30

<PAGE>



           (b) It may be  provided  pursuant  to  Section  301 with  respect  to
Registered  Securities  of any  series  denominated  in a  Foreign  Currency  or
currency  unit that  Holders  shall have the option,  subject to  paragraph  (d)
below,  to receive  payments of principal of,  premium,  if any, and interest on
such  Registered  Securities  in  such  Foreign  Currency  or  currency  unit by
delivering  to the  Trustee  (or to any duly  appointed  Paying  Agent)  for the
Registered  Securities  of that  series a  written  election,  to be in form and
substance  satisfactory to such Trustee (or to any such Paying Agent), not later
than the close of  business  on the  Election  Date  immediately  preceding  the
applicable  payment date. If a Holder so elects to receive such payments in such
Foreign  Currency or currency unit, such election will remain in effect for such
Holder until changed by such Holder by written  notice to the Trustee (or to any
such Paying  Agent) for the  Registered  Securities  of that  series;  PROVIDED,
HOWEVER,  that any such change must be made not later than the close of business
on the Election Date immediately preceding the next payment date to be effective
for the payment to be made on such payment date; and provided,  further, that no
such change or election  may be made with  respect to payments to be made on any
Registered Security of such series with respect to which an Event of Default has
occurred,  the Company has exercised any  defeasance,  satisfaction or discharge
options  pursuant to Article Four or notice of redemption  has been given by the
Company pursuant to Article Eleven. If any Holder makes any such election,  such
election  will not be  effective  as to any  transferee  of such Holder and such
transferee  shall be paid in Dollars unless such transferee makes an election as
specified above; PROVIDED, HOWEVER, that such election, if in effect while funds
are on deposit  with  respect to the  Registered  Securities  of such  series as
described in Section 404 or Section 405, will be effective on any  transferee of
such  Holder  unless  otherwise  specified  pursuant  to  Section  301 for  such
Registered Securities.  Any Holder of any such Registered Security who shall not
have delivered any such election to the Trustee (or to any duly appointed Paying
Agent) for the Registered  Securities of such series not later than the close of
business  on the  applicable  Election  Date will be paid the  amount due on the
applicable payment date in Dollars.

           (c)  With  respect  to  any  Registered   Securities  of  any  series
denominated in a Foreign  Currency or currency unit and payable in Dollars,  the
amount of Dollars so payable will be  determined  by the Currency  Determination
Agent based on the highest indicative quotation in The City of New York selected
by the Currency  Determination  Agent at approximately 11:00 A.M., New York City
time, on the second  Business Day preceding the  applicable  payment date.  Such
selection  shall  be made  from  among  the  quotations  appearing  on the  bank
composite or  multi-contributor  pages of the Reuters Monitor  Foreign  Exchange
Service or, if not available, the Telerate Monitor Foreign Exchange Service, for
three (or two if three are not  available)  major  banks in New York  City.  The
first three (or two) such banks  selected by the  Currency  Determination  Agent
which are offering quotes on the Reuters Foreign Exchange  Service,  as the case
may be,  shall be used.  If such  quotations  are  unavailable  from either such
foreign  exchange  service,  such  selection  shall be made from the  quotations
received by the  Currency  Determination  Agent from no more than three nor less
than two recognized foreign exchange dealers in The City of New York selected by
the Currency  Determination  Agent and approved by the Company (one of which may
be the Currency Determination Agent) for the purchase by the quoting dealer, for
settlement on such payment date, of the aggregate amount of the Foreign Currency
or  currency  unit  payable on such  payment  date in respect of all  Registered
Securities  denominated in such Foreign  Currency or currency unit and for which
the applicable dealer commits to execute a contract.  If fewer than two such bid
quotations  are  available  at 11:00  a.m.,  New York City  time,  on the second
Business Day preceding the applicable  payment date,  such payment will be based
on the  Market  Exchange  Rate  as of the  second  Business  Day  preceding  the
applicable  payment date. If the Market  Exchange Rate for such date is not then
available,  payments shall be made in the Foreign Currency or currency unit. All
currency  exchange  costs  associated  with any  payment  in Dollars on any such
Registered  Securities  will be borne by the Holder  thereof by deductions  from
such payment.

           (d) If a Conversion  Event occurs with respect to a Foreign  Currency
or currency unit in which Registered  Securities of any series are payable, then
with respect to each date for the

                                                             31

<PAGE>



payment of  principal  of,  premium,  if any,  and  interest  on the  Registered
Securities  of that series  occurring  after the last date on which such Foreign
Currency  or  currency  unit was used,  the  Company  may make such  payment  in
Dollars.  The Dollar  amount to be paid by the  Company to the  Trustee  for the
Registered Securities of such series and by such Trustee or any Paying Agent for
the  Registered  Securities  of such  series to the  Holders of such  Registered
Securities with respect to such payment date shall be determined by the Currency
Determination  Agent on the basis of the Market  Exchange  Rate as of the second
Business Day preceding the applicable  payment date or, if such Market  Exchange
Rate is not then available,  on the basis of the most recently  available Market
Exchange Rate, or as otherwise  established pursuant to Section 301 with respect
to such Notes.  Any payment in respect of such  Registered  Security  made under
such circumstances in Dollars will not constitute an Event of Default hereunder.

          (e) For purposes of this Indenture the following  terms shall have the
     following meanings:

          A "Component  Currency"  shall mean any currency  which is a component
     currency of any currency unit.

          "Election  Date"  shall mean,  for the  Registered  Securities  of any
     series, the date specified pursuant to Section 301(14).

     (f) Notwithstanding any other provisions of this Section 311, the following
shall apply:  (i) if the official unit of any  Component  Currency is altered by
way of  combination  or  subdivision,  the number of units of that currency as a
component shall be divided or multiplied in the same proportion,  (ii) if two or
more Component  Currencies are consolidated into a single currency,  the amounts
of those  currencies as components shall be replaced by an amount in such single
currency  equal  to the  sum  of  the  amounts  of  the  consolidated  Component
Currencies expressed in such a single currency,  (iii) if any Component Currency
is divided into two or more  currencies,  the amount of that original  Component
Currency  as a  component  shall be  replaced by the amounts of such two or more
currencies having an aggregate value on the date of division equal to the amount
of the former Component  Currency  immediately  before such division and (iv) in
the event of an official  redenomination  of any  currency  (including,  without
limitation, a currency unit), the obligations of the Company to make payments in
or with  reference to such currency on the  Registered  Securities of any series
shall, in all cases, be deemed immediately  following such  redenomination to be
obligations   to  make  payments  in  or  with   reference  to  that  amount  of
redenominated  currency  representing  the amount of such  currency  immediately
before such redenomination.

           (g) All  determinations  referred to in this  Section 311 made by the
Currency  Determination  Agent shall be in its sole discretion and shall, in the
absence of manifest  error,  be  conclusive  for all  purposes  and  irrevocably
binding   upon  the  Holders  of  the   applicable   Securities.   The  Currency
Determination  Agent shall  promptly give written  notice to the Trustee for the
Securities  of such series of any such decision or  determination.  The Currency
Determination  Agent shall  promptly  give written  notice to the Trustee of any
such decision or determination.  The Currency  Determination Agent shall have no
liability for any determinations referred to in this Section 311 made by it.

           (h) The Trustee for the  Securities  of a particular  series shall be
fully justified and protected in relying and acting upon information received by
it from the Company and the Currency  Determination Agent with respect to any of
the  matters  addressed  in or  contemplated  by this  Section 311 and shall not
otherwise   have  any  duty  or   obligation  to  determine   such   information
independently.

Section 312.        APPOINTMENT AND RESIGNATION OF CURRENCY DETERMINATION AGENT.

                                                             32

<PAGE>



           (a)  If  and so  long  as  the  Securities  of  any  series  (i)  are
denominated  in a currency unit or a currency  other than Dollars or (ii) may be
payable in a currency unit or a currency other than Dollars, or so long as it is
required  under any other  provision of this  Indenture,  then the Company shall
maintain with respect to each such series of  Securities,  or as so required,  a
Currency Determination Agent. The Company shall cause the Currency Determination
Agent to make the necessary  foreign exchange  determinations at the time and in
the manner specified  pursuant to Section 301 for the purpose of determining the
applicable  rate of  exchange  and for the  purpose  of  converting  the  issued
currency or currency unit into the applicable  payment currency or currency unit
for the  payment  of  principal  (and  premium,  if any) and  interest,  if any,
pursuant to Section 311.

           (b)  No  resignation  of  the  Currency  Determination  Agent  and no
appointment of a successor Currency Determination Agent pursuant to this Section
shall become  effective  until the  acceptance of  appointment  by the successor
Currency  Determination Agent as evidenced by a written instrument  delivered to
the Company and the Trustee of the  appropriate  series of Securities  accepting
such appointment executed by the successor Currency Determination Agent.

           (c) If the Currency  Determination  Agent shall resign, be removed or
become  incapable  of acting,  or if a vacancy  shall occur in the office of the
Currency  Determination  Agent for any cause,  with respect to the Securities of
one or more series, the Company, by a Board Resolution, shall promptly appoint a
successor Currency  Determination  Agent or Currency  Determination  Agents with
respect to the Securities of that or those series (it being  understood that any
such successor Currency Determination Agent may be appointed with respect to the
Securities of one or more or all of such series and that at any time there shall
only be one Currency  Determination  Agent with respect to the Securities of any
particular series).

                           SATISFACTION AND DISCHARGE
                           --------------------------

Section 401.         OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE.

     The Company  may, at the option of its Board of  Directors  evidenced  by a
Board  Resolution  set forth in an  Officers'  Certificate,  at any  time,  with
respect to the Securities of any series, elect to have either Section 402 or 403
be applied to all of the  Outstanding  Securities of that series upon compliance
with the conditions set forth below in this Article Four.

Section 402.         LEGAL DEFEASANCE AND DISCHARGE.

           Upon  the  Company's   exercise  under  Section  401  of  the  option
applicable  to this  Section  402,  the  Company  shall be  deemed  to have been
discharged  from its obligations  with respect to all Outstanding  Securities of
the  particular  series on the date the conditions set forth below are satisfied
(hereinafter, "Legal Defeasance"). For this purpose, such Legal Defeasance means
that the Company shall be deemed to have paid and discharged all the obligations
relating to the Outstanding Securities of that series and the Securities of that
series shall thereafter be deemed to be  "outstanding"  only for the purposes of
Section 406,  Section 408 and the other Sections of this  Indenture  referred to
below in this Section 402, and to have  satisfied  all of its other  obligations
under such  Securities and this Indenture and cured all then existing  Events of
Default (and the Trustee, on demand of and at the expense of the Company,  shall
execute proper  instruments  acknowledging  the same),  except for the following
which shall survive until otherwise terminated or discharged hereunder:  (a) the
rights of  Holders  of  outstanding  Securities  of the  particular  series  and
coupons,  if any, of such series to receive payments in respect of the principal
of, premium, if any, and interest, if any, on such Securities when such payments
are due

or on the  Redemption  Date  solely out of the trust  created  pursuant  to this
Indenture;  (b) the  Company's  obligations  with  respect  to  such  Securities
concerning  issuing  temporary  Securities of that series,  or, where  relevant,
registration of such Securities, mutilated, destroyed, lost or stolen Securities
of that series and the  maintenance of an office or agency for payment and money
for Security payments held in trust; (c) the rights,  powers, trusts, duties and
immunities of the Trustee for the  Securities of that series,  and the Company's
obligations  in  connection  therewith;  and  (d)  this  Article  Four  and  the
obligations set forth in Section 406 hereof.

           Subject  to  compliance  with this  Article  Four,  the  Company  may
exercise its option under Section 402  notwithstanding the prior exercise of its
option under Section 403 with respect to the Securities of a particular series.

Section 403.         COVENANT DEFEASANCE.

           Upon  the  Company's   exercise  under  Section  401  of  the  option
applicable  to this  Section  403,  the  Company  shall  be  released  from  any
obligations  under the covenants  contained in Sections 704, 801 and 1007 hereof
with respect to the Outstanding Securities of the particular series on and after
the date the  conditions set forth below are satisfied  (hereinafter,  "Covenant
Defeasance"),  and the Securities of that series shall  thereafter be deemed 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 such
covenants,  but shall continue to be deemed "Outstanding" for all other purposes
hereunder  (it  being  understood  that  such  Securities  shall  not be  deemed
outstanding for accounting purposes). For this purpose, such Covenant Defeasance
means that,  with respect to the  Outstanding  Securities  of that  series,  the
Company  may omit to comply with and shall have no  liability  in respect of any
term,  condition or limitation set forth in any such covenant,  whether directly
or indirectly,  by reason of any reference elsewhere herein to any such covenant
or by reason of any reference in any such covenant to any other provision herein
or in any other  document  and such  omission to comply  shall not  constitute a
default or Event of Default  under  subsection  501(3) but,  except as specified
above,  the remainder of this  Indenture and the Securities of that series shall
be unaffected thereby.

Section 404.         CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

           The following  shall be the  conditions to the  application of either
Section 402 or Section 403 to the outstanding Securities of a particular series:

          that  series,  cash in the  currency  or  currency  unit in which  the
          Securities of that series are payable  (except as otherwise  specified
          pursuant to Section 301 for the  Securities  of that series and except
          as provided in Sections  311(b) and 311(d),  in which case the deposit
          to be made  with  respect  to  Securities  for which an  election  has
          occurred  pursuant  to  Section  311(b),  or a  Conversion  Event  has
          occurred as provided in Section 311(d),  shall be made in the currency
          or currency unit in which the Securities of that series are payable as
          a result of such election or Conversion Event), Government Obligations
          or a combination thereof in such amounts as will be sufficient, in the
          opinion of an  internationally  recognized firm of independent  public
          accountants,  to pay the principal of, premium,  if any, and interest,
          if any,  due on the  outstanding  Securities  of that  series  and any
          related  coupons  at  the  Stated  Maturity,   or  on  the  applicable
          Redemption  Date, as the case may be, with respect to the  outstanding
          Securities of that series and any related coupons;

               (b) in the case of  Legal  Defeasance,  the  Company  shall  have

          of Counsel in the United States reasonably  acceptable to such Trustee
          confirming that, subject to customary assumptions and exclusions,  (1)
          the Company has received  from,  or there has been  published  by, the
          U.S. Internal Revenue Service a

               ruling or (2) since  the Issue  Date,  there has been a change in
          the  applicable  U.S.  federal  income tax law,  in either case to the
          effect that,  and based  thereon such Opinion of Counsel in the United
          States  shall  confirm  that,  subject to  customary  assumptions  and
          exclusions,  the Holders of the Outstanding  Securities of that series
          will not recognize  income,  gain or loss for U.S.  federal income tax
          purposes as a result of such Legal  Defeasance  and will be subject to
          U.S. federal income tax on the same amounts, in the same manner and at
          the same times as would  have been the case if such  Legal  Defeasance
          had not occurred;

                (c) in the case of Covenant  Defeasance,  the Company shall have
delivered to the Trustee for the Securities of that series an Opinion of Counsel
in the United  States  reasonably  acceptable to such Trustee  confirming  that,
subject to customary assumptions and exclusions,  the Holders of the Outstanding
Securities  of that  series  will not  recognize  income,  gain or loss for U.S.
federal income tax purposes as a result of such Covenant  Defeasance and will be
subject  to such 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;

                (d) no Event of Default or event which with the giving of notice
or the lapse of time, or both,  would become an Event of Default with respect to
the  Securities of that series shall have occurred and be continuing on the date
of such deposit and no Event of Default under Section  501(5) or Section  501(6)
shall have occurred and be continuing on the 123rd day after such date;

                (e) such  Legal  Defeasance  or  Covenant  Defeasance  shall not
result in a breach or violation  of, or  constitute a default under any material
agreement or  instrument to which the Company is a party or by which the Company
is bound;
                (f) the  Company  shall have  delivered  to the  Trustee for the
Securities of that series an Officers'  Certificate and an Opinion of Counsel in
the  United  States  (which  opinion of  counsel  may be  subject  to  customary
assumptions and exclusions) each stating that all conditions  precedent provided
for or relating to the Legal Defeasance or the Covenant Defeasance,  as the case
may be, have been complied with.

Section 405.         SATISFACTION AND DISCHARGE OF INDENTURE.

           This  Indenture  will be  discharged  and will cease to be of further
effect as to all  Securities  of any  particular  series issued  hereunder  when
either (i) all Securities of that series theretofore authenticated and delivered

as provided in Section 305, (B) lost, stolen or destroyed  Securities or coupons
of such series which have been  replaced or paid as provided in Section 306, (C)

relevant Redemption Date, whose surrender is not required as provided in Section
1106 and (D)  Securities  and coupons of such series for whose payment money has
theretofore  been  deposited  in trust and  thereafter  repaid to the Company or
discharged  from such trust,  as provided in the last paragraph of Section 1003)
have been  delivered  to the  Trustee  for the  Securities  of that  series  for
cancellation  or  (ii)  (A)  all  Securities  of that  series  and  any  coupons
appertaining  thereto not theretofore  delivered to Trustee for cancellation are
due and payable by their terms within one year or have become due and payable by
reason of the making of a notice of redemption  and the Company has  irrevocably
deposited or caused to be deposited with such Trustee as trust funds in trust an
amount of cash in any  combination  of currency  or  currency  unit in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series and except as provided in Sections
311(b)  and  311(d),  in which  case the  deposit  to be made  with  respect  to
Securities  for which an election has occurred  pursuant to Section  311(b) or a
Conversion  Event has occurred as provided in Section  311(d),  shall be made in

series with respect to that series under  Sections  407, 408, 409, and 410 shall
survive.  Nothing  contained  in this  Article  Four shall  abrogate  any of the

represented  by such Security  shall be fully  discharged to the extent that the
deposit made with respect to such Security  shall be converted into the currency
or currency unit in which such Security is payable.  The Trustee shall return to
the Company any  non-converted  funds or securities in its possession after such
payments have been made.

Section 407.         ACKNOWLEDGMENT OF DISCHARGE BY TRUSTEE.

written notice to the Holder of such Security in the manner set forth in Section
106, 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,  any

under this  Indenture  and the  Securities  of that series  shall be revived and
reinstated  as though no deposit had occurred  pursuant to Section 402, 403, 404

permitted to apply all such cash or Government  Obligations  in accordance  with
Section 402, 403, 404 or 405;  PROVIDED,  HOWEVER,  that if the Company has made
any  payment  of  principal,  premium,  if any,  and  interest,  if any,  on any
Securities  and  any  related  coupons  because  of  the  reinstatement  of  its
obligations,  the Company  shall be  subrogated  to the rights of the Holders of
such  Securities  and such  coupons to  receive  such  payment  from the cash or
Government Obligations, as applicable, held by such Trustee or Paying Agent.

           If an Event of  Default  with  respect  to any  particular  series of
Securities and any related coupons occurs and is continuing (other than an Event
of Default  described in Section 501(5) or 501(6)),  then and in every such case
either the Trustee for the  Securities of such series or the Holders of not less
than 25% in principal  amount of the  Outstanding  Securities of that series may
declare the entire principal amount (or, in the case of (i) OID Securities, such
lesser amount as may be provided for in the terms of that series or (ii) Indexed
Securities,  the amount  determined  in accordance  with the specified  terms of
those  Securities) of all the  Securities of that series,  to be due and payable
immediately, by a notice in writing to the Company (and to such Trustee if given
by Holders),  and upon any such  declaration of  acceleration  such principal or
such lesser amount,  as the case may be, together with accrued  interest and all
other amounts owing hereunder, shall become immediately due and payable, without
presentment,  demand,  protest  or notice of any kind,  all of which are  hereby
expressly waived.

           If any Event of Default  specified in Section 501(5) or 501(6) occurs
with  respect to the  Company,  all of the unpaid  principal  amount (or, if the
Securities of any series then  outstanding are (i) OID  Securities,  such lesser
amount  as may be  provided  for in the  terms of that  series  or (ii)  Indexed
Securities,  the amount  determined  in accordance  with the specified  terms of
those  Securities)  and accrued  interest on all  Securities of each series then
outstanding  shall IPSO FACTO become and be immediately  due and payable without
any declaration or other act by the Trustee or any Holder.

           At any time after such a declaration  of  acceleration  has been made
and before a judgment or decree for  payment of the money due has been  obtained
by the Trustee for the  Securities of any series as  hereinafter in this Article
provided,  the  Holders of a majority  in  principal  amount of the  Outstanding
Securities  of that series,  by written  notice to the Company and such Trustee,
may rescind and annul such declaration and its consequences if:

                     (1) the Company has paid or  deposited  with such Trustee a
           sum  sufficient  to pay in the currency or currency unit in which the
           Securities of such series are payable (except as otherwise  specified
           pursuant to Section 301 for the  Securities of such series and except
           as provided in Sections 311(b) and 311(d).

                    Securities  of that series  which have become due  otherwise
                    than  by  such  declaration  of  acceleration  and  interest
                    thereon  from the date such  principal  became due at a rate
                    per annum equal to the rate borne by the  Securities of such
                    series  (or,  in  the  case  of  (i)  OID  Securities,   the
                    Securities'  Yield to Maturity or (ii)  Indexed  Securities,

                    interest shall be legally enforceable;

                    (C) to the extent that  payment of such  interest is lawful,
                    interest upon overdue  interest at a rate per annum equal to
                    the rate borne by the  Securities of such series (or, in the
                    case  of  (i)  OID  Securities,  the  Securities'  Yield  to
                    Maturity or (ii) Indexed Securities,  the rate determined in
                    accordance  with the specified  terms of those  Securities);
                    and

                    (D) all sums paid or advanced by such Trustee  hereunder and
                    the reasonable  compensation,  expenses,  disbursements  and
                    advances  of such  Trustee,  its agents and  counsel and all
                    other amounts due to such Trustee under Section 607;

           and
                     (2) all Events of Default with respect to the Securities of
           such series, other than the nonpayment of the principal of Securities
           of that series which has become due solely by such acceleration, have
           been cured or waived as provided in Section  513. No such  rescission
           shall affect any  subsequent  default or impair any right  consequent
           thereon.

Section 503.    COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

           The Company covenants that if:

                     (1) default is made in the payment of any interest upon any
           Security of any series and any  related  coupons  when such  interest
           becomes due and payable and such default continues for a period of 30
           days; or

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

the Company will,  upon demand of the Trustee for the Securities of such series,
pay to it, for the benefit of the Holders of such  Securities  and coupons,  the
whole amount then due and payable on such  Securities  and coupons for principal
(and  premium if any) and  interest,  if any,  with  interest  upon the  overdue
principal (and premium, if any) and, to the extent that payment of such interest
shall be legally  enforceable,  upon any overdue  installments  of interest at a
rate per annum  equal to the rate borne by such  Securities  (or, in the case of
(i)  OID  Securities,   the  Securities'  Yield  to  Maturity  or  (ii)  Indexed
Securities,  the rate determined in accordance with the specified terms of those
Securities);  and,  in  addition  thereto,  such  further  amount  as  shall  be
sufficient  to cover  the  costs  and  expenses  of  collection,  including  the
reasonable compensation,  expenses,  disbursements and advances of such Trustee,
its agents and counsel and all other  amounts due to such Trustee  under Section
607.

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

           If an Event of Default with respect to Securities  of any  particular
series occurs and is  continuing,  the Trustee for the Securities of such series
may in its discretion proceed to protect

                                                             40

and  enforce  its  rights and the rights of the  Holders of  Securities  of that
series by such appropriate  judicial proceedings as such Trustee shall deem most
effectual  to protect  and  enforce any such  rights,  whether for the  specific
enforcement  of any  covenant or  agreement  in this  Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

Section 504.         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  relating  to the  Company  or any other  obligor  upon the
Securities of any series or the property of the Company or of such other obligor
or their creditors,  the Trustee for the Securities of such series (irrespective
of whether  the  principal  (or,  if the  Securities  of such series are (i) OID
Securities  or (ii)  Indexed  Securities,  such amount as may be due and payable
with respect to such  Securities  pursuant to a declaration  in accordance  with
Section  502) of any  Security of such  series  shall then be due and payable as
therein  expressed or by  declaration or otherwise and  irrespective  of whether
such  Trustee  shall  have made any  demand on the  Company  for the  payment of
overdue principal or interest) shall be entitled and empowered,  by intervention
in such proceeding or otherwise

                               (i) to  file  and  prove a  claim  for the  whole
                     amount of principal  (or, if the  Securities of such series
                     are (i) OID  Securities  or (ii) Indexed  Securities,  such
                     amount  as may be due  and  payable  with  respect  to such
                     Securities  pursuant to a declaration  in  accordance  with
                     Section 502) (and premium,  if any) and  interest,  if any,
                     owing  and  unpaid in  respect  of the  Securities  of such
                     series  and any  related  coupons  and to file  such  other
                     papers or  documents  as may be  necessary  or advisable in
                     order to have the  claims of such  Trustee  (including  any
                     claim   for   the   reasonable   compensation,    expenses,
                     disbursements and advances of such Trustee,  its agents and
                     counsel  and all other  amounts due to such  Trustee  under
                     Section 607) and of the Holders of the  Securities  of such
                     series and any  related  coupons  allowed in such  judicial
                     proceeding;

                         (ii)  to  collect  and  receive  any  moneys  or  other
                    property  payable or  deliverable  on any such claims and to
                    distribute the same; and

                         (iii)   unless   prohibited   by  law   or   applicable
                    regulations,  to  vote  on  behalf  of  the  Holders  of the
                    Securities  of such  series in any  election of a trustee in
                    bankruptcy or other person performing similar functions;

and any receiver, assignee, trustee, liquidator,  sequestrator (or other similar
official) in any such judicial proceeding is hereby authorized by each Holder of
Securities  and coupons to make such payments to such Trustee,  and in the event
that such Trustee shall  consent to the making of such payments  directly to the
Holders of Securities  and coupons,  to pay to such Trustee any amount due to it
for the reasonable  compensation,  expenses,  disbursements and advances of such
Trustee,  its agents and counsel,  and any other  amounts due such Trustee under
Section 607.

           Nothing herein contained shall be deemed to authorize the Trustee for
the  Securities  of any series to  authorize or consent to or accept or adopt on
behalf  of any  Holder  of a  Security  or  coupon  any plan of  reorganization,
arrangement,  adjustment or composition  affecting the Securities of such series
or the  rights of any  Holder  thereof,  or to  authorize  the  Trustee  for the
Securities  or  coupons  of any  series to vote in  respect  of the claim of any
Holder  in any such  proceeding,  except as  aforesaid,  for the  election  of a
trustee in bankruptcy or other person performing similar functions.

Section 505. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES OR
             COUPONS.

Securities  or  coupons  of any series may be  prosecuted  and  enforced  by the
Trustee for the  Securities of any series  without the  possession of any of the
Securities or coupons of such series or the production thereof in any proceeding
relating  thereto,  and any such proceeding  instituted by such Trustee shall be
brought  in its own name as trustee of an express  trust,  and any  recovery  of
judgment shall, after provision for the payment of the reasonable  compensation,
expenses, disbursements and advances of such Trustee, its agents and counsel and
all other  amounts due to such  Trustee  under  Section  607, be for the ratable
benefit of the Holders of the  Securities  and coupons of such series in respect
of which such judgment has been recovered.

pursuant  to this  Article  with  respect to the  Securities  or coupons of such

thereof if fully paid:

               FIRST:  To the  payment of all  amounts  due such  Trustee  under
          Section 607;

               SECOND:  To the payment of the  amounts  then due and unpaid upon

          of which or for the  benefit of which  such money has been  collected,

          amounts due and payable on such  Securities  and coupons for principal
          (and premium, if any) and interest, if any, respectively; and

               Third:  The  balance,  if any, to the Person or Persons  entitled

Section 507.         LIMITATION ON SUITS.

           No Holder of any  Security  of any  particular  series or any related
coupons shall have any right to institute any proceeding, judicial or otherwise,
with respect to this Indenture, or for the appointment of a receiver or trustee,
or for any other remedy hereunder, unless:

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

                     (2) the Holders of not less than 25% in principal amount of
           the  Outstanding  Securities  of that series  shall have made written
           request to the Trustee for the Securities of such series 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 such  Trustee
           reasonable  indemnity against the costs,  expenses and liabilities to
           be incurred in compliance with such request;

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

                                                             42

<PAGE>



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

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

Section 508.  UNCONDITIONAL  RIGHT OF HOLDERS TO RECEIVE PRINCIPAL (AND PREMIUM,
IF ANY) AND INTEREST, IF ANY.

           Notwithstanding any other provision in this Indenture,  the Holder of
any Security or coupon shall have the right which is absolute and  unconditional
to receive  payment of the  principal of (and  premium,  if any) and (subject to
Section  307)  interest,  if any,  on such  Security  on the  respective  Stated
Maturities  expressed in such Security or coupon (or, in the case of redemption,
on the Redemption  Date) 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 509.         RESTORATION OF RIGHTS AND REMEDIES.

           If the  Trustee for the  Securities  of any series or any Holder of a
Security or 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 such Trustee or to such Holder,
then and in every  such  case the  Company,  such  Trustee  and the  Holders  of
Securities or coupons 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 such  Trustee  and such  Holders  shall
continue as though no such proceeding had been instituted.

Section 510.         RIGHTS AND REMEDIES CUMULATIVE.

           Except as  otherwise  provided  with  respect to the  replacement  or
payment of  mutilated,  destroyed,  lost or stolen  Securities or coupons in the
last  paragraph  of Section  306, no right or remedy  herein  conferred  upon or
reserved to the Trustee  for the  Securities  of any series or to the Holders of
Securities  or coupons is intended to be exclusive of any other right or remedy,
and every right and remedy shall, to the extent  permitted by law, be cumulative
and in  addition  to every  other  right and remedy  given  hereunder  or now or
hereafter existing at law or in equity or otherwise. The assertion or employment
of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

Section 511.         DELAY OR OMISSION NOT WAIVER.

           No delay or omission of the Trustee for the  Securities of any series
or of any Holder of any  Security of such series to exercise any right or remedy
accruing upon any Event of Default with respect to the Securities of such series
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 such Trustee for the Securities or coupons of any series or
to the Holders may be exercised from time to time, and as often as may be deemed
expedient, by such Trustee or by the Holders, as the case may be.

                                                             43

<PAGE>



Section 512.         CONTROL BY HOLDERS.

           The  Holders of a majority  in  principal  amount of the  Outstanding
Securities  of any  particular  series  shall have the right to direct the time,
method and place of conducting any  proceeding  for any remedy  available to the
Trustee for the Securities of such series with respect to the Securities of that
series or exercising  any trust or power  conferred on such Trustee with respect
to such Securities, provided that:

                    (1) such direction shall not be in conflict with any rule of
               law or with this  Indenture  and could not involve the Trustee in
               personal liability; and

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

Section 513.         WAIVER OF PAST DEFAULTS.

           The  Holders of not less than a majority in  principal  amount of the
Outstanding  Securities of any particular  series and any related coupons may on
behalf  of the  Holders  of all the  Securities  of that  series  waive any past
default hereunder with respect to that series and its consequences, except:

                    (1) a  default  in  the  payment  of  the  principal  of (or
               premium,  if any) or  interest,  if any, on any  Security of that
               series; or

                    (2) a default with respect to a covenant or provision hereof
               which under  Article  Nine cannot be modified or amended  without
               the  consent of the Holder of each  Outstanding  Security of that
               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 514.         UNDERTAKING FOR COSTS.

           All parties to this Indenture  agree, and each Holder of any Security
or coupon 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 the
Securities  or coupons  of any  series for any action  taken or omitted by it as
Trustee,  the filing by any party litigant in such suit of an undertaking to pay
the  costs of such  suit,  and that  such  court  may in its  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 shall not apply to any suit instituted by the Trustee for the Securities
of any  series,  to any suit  instituted  by any  Holder,  or group of  Holders,
holding in the aggregate  more than 10% in principal  amount of the  Outstanding
Securities of any particular  series or to any suit  instituted by any Holder of
any Security or coupon for the  enforcement  of the payment of the  principal of
(or premium, if any) or interest,  if any, on any Security of such series or the
payment of any coupon on or after the respective Stated Maturities  expressed in
such  Security  or  coupon  (or,  in the case of  redemption,  on or  after  the
Redemption Date).

Section 515.         WAIVER OF STAY OR EXTENSION LAWS.

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

                                                             45

<PAGE>



covenants  that it will not hinder,  delay or impede the  execution of any power
herein granted to the Trustee for any series of Securities,  but will suffer and
permit the execution of every such power as though no such law had been enacted.

Section 516.         JUDGMENT CURRENCY.

           If, for the purpose of obtaining a judgment in any court with respect
to any obligation of the Company  hereunder or under any Security or any related
coupon, it shall become necessary to convert into any other currency or currency
unit any amount in the  currency or currency  unit due  hereunder  or under such
Security  or  coupon,  then  such  conversion  shall  be  made  by the  Currency
Determination  Agent at the  Market  Exchange  Rate as in  effect on the date of
entry of the judgment (the "Judgment  Date").  If pursuant to any such judgment,
conversion  shall  be made on a date  (the  "Substitute  Date")  other  than the
Judgment Date and there shall occur a change between the Market Exchange Rate as
in effect on the Judgment Date and the Market  Exchange Rate as in effect on the
Substitute Date, the Company agrees to pay such additional  amounts,  if any, as
may be  necessary  to ensure that the amount paid is equal to the amount in such
other  currency or currency unit which,  when  converted at the Market  Exchange
Rate as in effect on the  Judgment  Date,  is the amount due  hereunder or under
such Security or coupon.  Any amount due from the Company under this Section 516
shall be due as a separate  debt and is not to be affected by or merged into any
judgment  being  obtained for any other sums due  hereunder or in respect of any
Security or coupon. In no event,  however,  shall the Company be required to pay
more in the currency or currency  unit due  hereunder or under such  Security or
coupon at the Market  Exchange  Rate as in effect on the Judgment  Date than the
amount of  currency or currency  unit stated to be due  hereunder  or under such
Security or coupon so that in any event the Company's  obligations  hereunder or
under such Security or coupon will be  effectively  maintained as obligations in
such  currency or currency  unit,  and the Company shall be entitled to withhold
(or be  reimbursed  for,  as the case may be) any excess of the amount  actually
realized upon any such conversion on the Substitute Date over the amount due and
payable on the Judgment Date.

                                    ARTICLE 6

                                   THE TRUSTEE
                                   -----------

Section 601.         CERTAIN DUTIES AND RESPONSIBILITIES.

               (a) Except  during the  continuance  of an Event of Default  with
          respect  to the  Securities  of any  series  for which the  Trustee is
          serving as such,

                     (1) such 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 such Trustee; and

                     (2) in the absence of bad faith on its part,  such  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 such Trustee and conforming to the requirements
           of this  Indenture;  but in the  case  of any  such  certificates  or
           opinions which by any provisions hereof are specifically  required to
           be furnished to such  Trustee,  such Trustee shall be under a duty to
           examine  the same to  determine  whether  or not they  conform to the
           requirements of this Indenture.

           (b) In  case  an  Event  of  Default  with  respect  to a  series  of
Securities  has occurred and is  continuing,  the Trustee for the  Securities of
such series shall exercise such of the rights and

                                       46

<PAGE>



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  for  Securities  of any  series  from  liability  for its  own  grossly
negligent  action,  its own grossly negligent failure to act, or its own willful
misconduct, except that:

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

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

                    (3) such  Trustee  shall not be liable  with  respect to any
               action taken, suffered 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 of any particular
               series,  determined  as provided in Section 512,  relating to the
               time,  method  and place of  conducting  any  proceeding  for any
               remedy  available to such  Trustee,  or  exercising  any trust or
               power  conferred  upon such Trustee,  under this  Indenture  with
               respect to the Securities of that series; and

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

          (d) Whether or not therein  expressly so provided,  every provision of
     this  Indenture  relating to the conduct or affecting  the  liability of or
     affording  protection to the Trustee for any series of Securities  shall be
     subject to the provisions of this Section.

Section 602.         NOTICE OF DEFAULTS.

           Within 90 days after the  occurrence  of any default  hereunder  with
respect to Securities of any particular  series,  the Trustee for the Securities
of such series shall give to Holders of Securities of that series, in the manner
set forth in Section 106,  notice of such default known to such Trustee,  unless
such default shall have been cured or waived; PROVIDED, HOWEVER, that, except in
the case of a default in the payment of the principal of (or premium, if any) or
interest,  if any,  on any  Security  of that  series,  or in the deposit of any
sinking fund payment with  respect to  Securities  of that series,  such Trustee
shall be  protected  in  withholding  such notice if and so long as the board of
directors,  the  executive  committee or a trust  committee of directors  and/or
Responsible  Officers  of  such  Trustee  in  good  faith  determines  that  the
withholding  of such notice is in the interest of the Holders of  Securities  of
that series and related coupons; and PROVIDED,  FURTHER, that in the case of any
default of the character  specified in Section 501(3) with respect to Securities
of that series no such  notice to Holders  shall be given until at least 60 days
after  the  occurrence  thereof.  For the  purpose  of this  Section,  the  term
"default"  means  any event  which is, or after  notice or lapse of time or both
would become, an Event of Default with respect to Securities of that series.

Section 603.         CERTAIN RIGHTS OF TRUSTEE.

           Except as otherwise provided in Section 601:

           (a) the  Trustee  for any  series of  Security  may rely and shall be
protected in acting or refraining from acting upon any resolution,  certificate,

Board Resolution;

           (c) whenever in the  administration  of this  Indenture  such Trustee
shall deem it desirable that a matter be proved or established  prior to taking,
suffering or omitting any action hereunder,  such Trustee (unless other evidence
be herein specifically prescribed) may, in the absence of bad faith on its part,
rely upon an Officers' Certificate;

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

           (e) such Trustee  shall be under no obligation to exercise any of the
rights or powers  vested in it by this  Indenture at the request or direction of
any of the Holders of  Securities of any series  pursuant to this  Indenture for

liabilities  which might be incurred by it in  compliance  with such  request or
direction;
           (f) such Trustee  shall not be bound to make any  investigation  into
the  facts  or  matters  stated  in  any  resolution,   certificate,  statement,

debenture or other paper or document,  but such Trustee, in its discretion,  may
make such further inquiry or investigation  into such facts or matters at it may
see fit,  and, if such Trustee shall  determine to make such further  inquiry or
investigation,  it shall be entitled to examine the books,  records and premises
of the Company, personally or by agent or attorney; and

     of  competent  jurisdiction  for  the  removal  of  such  Trustee  and  the

               (e) If the Trustee for the Securities of any series shall resign,
          be removed or become incapable of acting,  or if a vacancy shall occur
          in the  office of  Trustee  for the  Securities  of any series for any

          the Securities of such series shall be appointed by Act of the Holders

          Section 611,  become the successor  Trustee for the Securities of such

          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

the  Securities  of any series  shall  execute,  acknowledge  and deliver to the
Company and to the retiring  Trustee an instrument  accepting such  appointment,

effective  and  such  successor   Trustee  without  any  further  act,  deed  or
conveyance,  shall become vested with all the rights,  powers, trusts and duties
of the  retiring  Trustee;  but, on the request of the Company or the  successor
Trustee,  such retiring Trustee shall, upon payment of its charges,  execute and
deliver an instrument  transferring  to such  successor  Trustee all the rights,
powers and trusts of the retiring  Trustee and shall duly  assign,  transfer and
deliver to such  successor  Trustee all property and money held by such retiring
Trustee hereunder.

           (b) In case of the appointment  hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company,  the
retiring  Trustee and each  successor  Trustee with respect to the Securities of
one or more series 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,  each  successor  Trustee  all the  rights,  powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates,  (2)
if the retiring  Trustee is not retiring with respect to all  Securities,  shall
contain  such  provisions  as shall be deemed  necessary or desirable to confirm

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 and each such Trustee shall be trustee of a trust or trusts hereunder
separate and apart from any trust or trusts hereunder administered by any

                                                             51

other such Trustee;  and upon the  execution  and delivery of such  supplemental
indenture  the  resignation  or removal of the  retiring  Trustee  shall  become
effective  to the  extent  provided  therein  and each such  successor  Trustee,
without any further act,  deed or  conveyance,  shall become vested with all the
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;  but, on request of the Company or any successor Trustee,  such
retiring  Trustee  shall duly  assign,  transfer  and deliver to such  successor
Trustee all  property and money held by such  retiring  Trustee  hereunder  with
respect to the  Securities of that or those series to which the  appointment  of
such successor Trustee relates.

           (c) Upon request of any such  successor  Trustee,  the Company  shall
execute  any and all  instruments  for more fully and  certainly  vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in Subsections (a) or (b) of this Section, as the case may be.

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

Section 612.        MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

     Any corporation into which the Trustee for the Securities of any series 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 Trustee
shall be a party, or any corporation  succeeding to all or substantially  all of
the corporate  trust  business of such  Trustee,  shall be the successor of such
Trustee  hereunder,  provided such corporation shall be otherwise  qualified and
eligible under this Article, 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  or the
Authenticating  Agent for such series then in office,  any  successor by merger,
conversion or consolidation  to such  authenticating  Trustee or  Authenticating
Agent,  as the case may be,  may  adopt  such  authentication  and  deliver  the
Securities so authenticated with the same effect as if such successor Trustee or
successor Authenticating Agent had itself authenticated such Securities.

Section 613.         PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

           The Trustee is subject to Section 311(a) of the Trust  Indenture Act,
excluding  any  creditor  relationship  listed  in  Section  311(b) of the Trust
Indenture  Act. A Trustee who has resigned or been  removed  shall be subject to
Section 311(a) of the Trust Indenture Act to the extent indicated.

Section 614.         AUTHENTICATING AGENTS.

           From time to time the Trustee for the  Securities  of any series may,
subject to its sole discretion,  appoint one or more Authenticating  Agents with
respect to the  Securities of such series,  which may include the Company or any
Affiliate of the Company,  with power to act on the Trustee's behalf and subject
to its  discretion  in the  authentication  and delivery of  Securities  of such
series in connection  with  transfers and exchanges  under Sections 304, 305 and
1107 as fully to all intents and  purposes as though such  Authenticating  Agent
had  been   expressly   authorized  by  those  Sections  of  this  Indenture  to
authenticate  and deliver  Securities  of such series.  For all purposes of this
Indenture,  the  authentication  and delivery of Securities of such series by an
Authenticating  Agent for such  Securities  pursuant  to this  Section  shall be
deemed to be authentication and delivery of such Securities "by the Trustee" for
the Securities of such series. Any such Authenticating  Agent shall at all times
be a  corporation  organized  and doing  business  under the laws of the  United
States or of any State, authorized under such laws to

                                                             52

<PAGE>



exercise  corporate  trust powers,  having a combined  capital and surplus of at
least  $50,000,000 and subject to supervision or examination by Federal or State
authority.  If such Authenticating Agent publishes reports of condition at least
annually  pursuant to law or the  requirements of such  supervising or examining
authority,  then for the  purposes  of this  Section  the  combined  capital and
surplus  of such  corporation  shall be deemed to be its  combined  capital  and
surplus as set forth in its most recent report of condition so published.  If at
any time an Authenticating  Agent for any series of Securities shall cease to be
eligible in accordance with the provisions of this Section,  such Authenticating
Agent shall resign  immediately  in the manner and with the effect  specified in
this Section.

           Any corporation into which any Authenticating  Agent may be merged or
converted or with which it may be  consolidated,  or any  corporation  resulting
from any merger,  consolidation or conversion to which any Authenticating  Agent
shall be a party, or any corporation  succeeding to the corporate trust business
of any Authenticating Agent, shall be the successor of such Authenticating Agent
hereunder,  if such  successor  corporation  is  otherwise  eligible  under this
Section,  without the execution or filing of any paper or any further act on the
part of the  parties  hereto  or the  Authenticating  Agent  or  such  successor
corporation.

           Any  Authenticating  Agent for any series of Securities may resign at
any time by giving  written notice of resignation to the Trustee for such series
and to the  Company.  The Trustee for any series of  Securities  may at any time
terminate the agency of any  Authenticating  Agent by giving  written  notice of
termination  to such  Authenticating  Agent and to the Company in the manner set
forth in Section 105. Upon receiving such a notice of resignation or upon such a
termination,  or in case at any time any Authenticating  Agent for any series of
Securities  shall cease to be eligible under this Section,  the Trustee for such
series may appoint a successor  Authenticating  Agent, shall give written notice
of such  appointment  to the  Company  and  shall  give  written  notice of such
appointment  to all Holders of Securities of such series in the manner set forth
in Section 106. 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 Trustee for the  Securities  of each series  agrees to pay to any
Authenticating  Agent for such series from time to time reasonable  compensation
for its services,  and such Trustee shall be entitled to be reimbursed  for such
payments, subject to Section 607.

           If an appointment with respect to one or more series of Securities is
made pursuant to this Section,  the  Securities of such series may have endorsed
thereon,  in addition  to the  Trustee's  certification  of  authentication,  an
alternate certificate of authentication in the following form:

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

the Securities of any such series,  and furnish to such Trustee reasonable proof
that each such  applicant has owned a Security of that series for a period of at

Securities  of that series with respect to their rights under this  Indenture or

           If any such Trustee shall elect not to afford such applicants  access
to that  information,  such  Trustee  shall,  upon the  written  request of such
applicants,  mail to each Holder of  Securities  of that  series  whose name and
address  appears in the  information  preserved  at the time by such  Trustee in
accordance  with  Section  702(a),  a  copy  of  the  form  of  proxy  or  other
communication  which is specified in such request,  with  reasonable  promptness

agent of either of them shall be held accountable by reason of the disclosure of
any such  information  as to the  names  and  addresses  of the  Holders  of the
Securities of such series in accordance with Section  702(b),  regardless of the
source from which such  information was derived,  and that the Trustee shall not
be held accountable by reason of mailing any material pursuant to a request made
under Section 702(b).

           (a) Within 60 days after  March 15 of each year,  the Trustee for the

Sections 313(b), 313(c) and 313(d) of the Trust Indenture Act.

           (b) At the time that the  Trustee for the  Securities  of each series
mails  such a report to the  Holders of  Securities  of such  series,  each such
Trustee shall file a copy of that report with the Commission and with each stock

terms of the  Securities of such series,  any coupons  appertaining  thereto and
this Indenture.  Unless otherwise  specified as contemplated by Section 301 with
respect to any series of Securities, any interest due on Bearer Securities on or
before  Maturity  shall be payable only upon  presentation  and surrender of the
several coupons for such interest  installments as are evidenced thereby as they
severally  mature.  The  interest,  if any,  due in respect of any  temporary or
permanent  Global  Security,  together with any  additional  amounts  payable in
respect thereof, as provided in the terms and conditions of such Security, shall
be  payable,  subject to the  conditions  set forth in Section  1012,  only upon
presentation of such Security to the Trustee thereof for notation thereon of the
payment of such interest.

Section 1002.                  MAINTENANCE OF OFFICE OR AGENCY.

           If Securities of a series are issuable only as Registered  Securities
the Company will  maintain in each Place of Payment for that series an office or
agency  where  Securities  of that series may be presented  or  surrendered  for
payment,  an office or agency where Securities of that series may be surrendered
for  registration  of transfer or exchange  and where  notices and demands to or
upon  the  Company  with  respect  to the  Securities  of that  series  and this
Indenture  may be  served.  If  Securities  of a series are  issuable  as Bearer
Securities,  the Company will maintain (A) an office or agency (which may be the
same  office or  agency)  in a Place of  Payment  for that  series in the United
States  where any  Registered  Securities  of that  series may be  presented  or
surrendered for payment,  where any Registered  Securities of that series may be
surrendered for registration of transfer, where Securities of that series may be
surrendered  for  exchange,  where notices and demands to or upon the Company in
respect of the  Securities  of that series and this  Indenture may be served and
where Bearer  Securities of that series and related  coupons may be presented or
surrendered  for  payment  in  the  circumstances  described  in  the  following
paragraph (and not otherwise), (B) subject to any laws or regulations applicable
thereto,  in a Place of Payment  for that  series  which is located  outside the
United States, an office or agency where

                                                             60

<PAGE>



Securities of that series and related  coupons may be presented and  surrendered
for payment; PROVIDED, HOWEVER, that if the Securities of that series are listed
on the Stock  Exchange or any other stock  exchange  located  outside the United
States and such stock  exchange  shall so require,  the Company will  maintain a
Paying  Agent  for the  Securities  of that  series in  Luxembourg  or any other
required city located outside the United States,  as the case may be, so long as
the  Securities of that series are listed on such  exchange,  and (C) subject to
any laws or  regulations  applicable  thereto,  in a Place of  Payment  for that
series  located  outside  the  United  States  an  office  or  agency  where any
Registered  Securities of that series may be  surrendered  for  registration  of
transfer,  where  Securities of that series may be surrendered  for exchange and
where notices and demands to or upon the Company in respect of the Securities of
that  series and this  Indenture  may be served.  The  Company  will give prompt
written notice to the Trustee for the Securities of that series of the location,
and any change in the location, of any such office or agency. If at any time the
Company shall fail to maintain any such required  office or agency in respect of
any series of Securities or shall fail to furnish the Trustee for the Securities
of that series  with the  address  thereof,  such  presentations  (to the extent
permitted by law),  and  surrenders of Securities of that series may be made and
notices and demands may be made or served at the Corporate  Trust Office of such
Trustee,  except that Bearer  Securities of that series and the related  coupons
may be presented  and  surrendered  for payment at the offices  specified in the
Security,  and the Company hereby appoints the same as its agent to receive such
presentations, surrenders, notices and demands.

           No payment of principal (and premium, if any) or interest, if any, on
Bearer  Securities  shall be made at any office or agency of the  Company 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.
Payments  will  not  be  made  in  respect  of  Bearer   Securities  or  coupons
appertaining  thereto pursuant to presentation to the Company, or its designated
Paying Agents within the United States.  Notwithstanding the foregoing,  payment
of  principal  of (and  premium,  if any) and  interest,  if any,  on any Bearer
Security  denominated  and payable in Dollars  will be made at the office of the
Company's Paying Agent in the United States, if, and only if, payment in Dollars
of the full amount of such principal,  premium or interest,  as the case may be,
at all offices or agencies outside the United States maintained for that purpose
by the  Company in  accordance  with this  Indenture  is illegal or  effectively
precluded by exchange controls or other similar restrictions and the Company has
delivered to the Trustee an Opinion of Counsel to that effect.

           The  Company may also from time to time  designate  one or more other
offices or agencies (in or outside the Place of Payment) where the Securities of
one or  more  series  may be  presented  or  surrendered  for  any or all of the
purposes  specified above in this Section 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 such purpose.  The Company will give prompt written
notice to the Trustee for the  Securities of each series so affected of any such
designation  or rescission  and of any change in the location of any such office
or agency.

           If and so long as the Securities of any series (i) are denominated in
a currency  other than  Dollars or (ii) may be payable in a currency  other than
Dollars,  or so  long  as it is  required  under  any  other  provision  of  the
Indenture,  then the Company will  maintain  with respect to each such series of
Securities,  or as so required,  a Currency  Determination  Agent. Section 1003.

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 particular series of Securities and any related coupons, it will,
on or  before  each  due  date  of the  principal  of (and  premium,  if any) or
interest, if any, on any of the Securities of that series, segregate and hold in
trust for the benefit of the Persons entitled thereto a sum in the currency or

                                                             61

currency  unit in which the  Securities  of such series are  payable  (except as
otherwise  specified  pursuant to Section 301 for the  Securities of such series
and except as  provided in Sections  311(b) and  311(d))  sufficient  to pay the
principal (and premium, if any) and interest, if any, so becoming due until such
sums shall be paid to such Persons or otherwise  disposed of as herein provided,
and will  promptly  notify the Trustee for the  Securities of such series of its
action or failure so to act.

           Whenever  the Company  shall have one or more  Paying  Agents for any
particular series of Securities and any related coupons,  it will, prior to each
due date of the principal of (and premium,  if any) or interest,  if any, on any
such Securities, deposit with a Paying Agent for the Securities of such series a
sum (in the  currency or currency  unit  described in the  preceding  paragraph)
sufficient to pay the principal (and premium,  if any) and interest,  if any, 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  for  the
Securities of such series) the Company will promptly  notify such Trustee of its
action or failure so to act.

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

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

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

                     (3)  at any  time  during  the  continuation  of  any  such
           default,  upon the written request of such Trustee,  forthwith pay to
           such 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  for the
Securities  of any series all sums held in trust by the  Company or such  Paying
Agent,  such sums to be held by such  Trustee upon the same trusts as those upon
which such sums were held by the Company or such Paying  Agent;  and,  upon such
payment by any Paying Agent to such Trustee, such Paying Agent shall be released
from all further liability with respect to such money.

Section 1004.                  PAYMENT OF TAXES AND OTHER CLAIMS.

           The Company will pay or discharge or cause to be paid or  discharged,
before  the  same  shall  become  delinquent,  (1) all  taxes,  assessments  and
governmental  charges  levied or imposed upon it or upon its income,  profits or
property,  and (2) all lawful claims for labor, materials and supplies which, if
unpaid, might by law become a lien upon its property;  PROVIDED,  HOWEVER,  that
the Company  shall not be required  to pay or  discharge  or cause to be paid or
discharged any such tax, assessment, charge or claim whose amount, applicability
or validity is being contested in good faith by appropriate proceedings.

Section 1005.                  STATEMENTS AS TO COMPLIANCE.

                                                             62

<PAGE>



           The  Company   will  deliver  to  the  Trustee  for  each  series  of
Securities,  within  120 days  after  the end of each  fiscal  year,  a  written
statement signed by the principal executive officer, principal financial officer
or principal accounting officer of the Company stating that:

               (1) a review of the  activities  of the Company  during such year
          and of  performance  under  this  Indenture  has been  made  under his
          supervision; and

               (2) to the  best of his  knowledge,  based  on such  review,  the
          Company is in compliance  with all conditions and covenants under this
          Indenture.  For purposes of this  Section,  such  compliance  shall be
          determined  without  regard to any period of grace or  requirement  of
          notice provided under this Indenture.

Section 1006.                  CORPORATE EXISTENCE.

     Subject to Article Eight,  the Company will each do or cause to be done all
things  necessary  to preserve  and keep in full force and effect its  corporate
existence,  rights  (charter and statutory) and franchises;  PROVIDED,  HOWEVER,
that the Company shall not be required to preserve any right or franchise if the
Board of Directors of the Company shall determine that the preservation  thereof
is no longer  desirable  in the conduct of the  business of the Company and that
the loss thereof is not disadvantageous in any material respect to the Holders.

Section 1007.                  LIEN ON ASSETS

           If at any time the  Company  or any of its Gas  Utility  Subsidiaries
mortgages,  pledges or  otherwise  subjects to any lien the whole or any part of
any  Property  now owned or  hereafter  acquired  by it  except  as  hereinafter
provided  in this  Section  1007,  the  Company  shall,  or shall cause such Gas
Utility  Subsidiary to, secure the  then-Outstanding  Securities,  and any other
obligations  of the Company  which may then be  outstanding  and entitled to the
benefit of a covenant  similar in effect to this  covenant,  equally and ratably
with the indebtedness or obligations  secured by such mortgage,  pledge or lien,
for as long as any such indebtedness or obligation is so secured.  The foregoing
covenant shall not apply to: (1) the creation,  extension,  renewal or refunding
of  purchase-money  mortgages  or liens or other liens to which any  property or
asset acquired by the Company or any of its Gas Utility  Subsidiaries is subject
as of the date of its acquisition by the Company or such Gas Utility  Subsidiary
or at the time any  Subsidiary of the Company  becomes a Gas Utility  Subsidiary
under the  Indenture;  or (2) to the  making of any  deposit or pledge to secure
public or statutory obligations or contractual  obligations with the Long Island
Power Authority or with any  governmental  agency at any time required by law in
order to qualify the Company or any of its Gas Utility  Subsidiaries  to conduct
its  business  or any  part  thereof  or in  order  to  entitle  it to  maintain
self-insurance  or to obtain  the  benefits  of any law  relating  to  workmen's
compensation, unemployment insurance, old age pensions or other social security;
or with any court, board, commission or governmental agency as security incident
to the proper conduct of any proceeding  before it; or (3) any lien granted over
receivables or other monetary or regulatory  assets granted in connection with a
securitization  arrangement  for those assets to secure the  Company's or one of
its Gas Utility Subsidiaries'  monetary obligations incurred in relation to such
securitization arrangement, so long as the principal amount of those obligations
does not exceed the  aggregate  face amount of such  receivables  or monetary or
regulatory assets; or (4) liens for taxes,  assessments or governmental  charges
or levies not yet  delinquent  or being  contested in good faith by  appropriate
proceedings   diligently  conducted,   if  such  reserve  or  other  appropriate
provision,  if any,  as shall  be  required  by  generally  accepted  accounting
principles shall have been made therefor; or (5) liens of landlords and liens of
mechanics and  materialmen  incurred in the ordinary course of business for sums
not  yet due or  being  contested  in  good  faith  by  appropriate  proceedings
diligently conducted, if such reserve or other appropriate provision, if any, as
shall be required by generally accepted accounting  principles,  shall have been
made therefor; or (6) leases or subleases granted to others in the

ordinary course of business; or (7) easements,  rights-of-way,  restrictions and
other similar  encumbrances  incurred in the ordinary course of business and not
interfering  with the ordinary  conduct of the  business of the Company;  or (8)
liens  incurred  in  connection  with  the  issuance  by a  state  or  political
subdivision  thereof of any  securities  the  interest  on which is exempt  from
federal  income  taxes by virtue of Section 103 of the Code or any other laws or
regulations  in effect at the time of such  issuance;  or (9) liens for the sole
purpose of extending, renewing or replacing in whole or in part the indebtedness
secured by any lien  referred  to in the  foregoing  clauses or in this  clause,
PROVIDED,  HOWEVER,  that the principal  amount of indebtedness  secured thereby
shall not exceed the  principal  amount of  indebtedness  secured at the time of
such  extension,  renewal or  replacement  and that such  extension,  renewal or
replacement  shall be limited to all or a part of the property which secured the
lien so extended,  renewed or replaced  (plus  improvements  on such  property).
Nothing  contained in this Indenture  prevents any entity other than the Company
or its Gas Utility  Subsidiaries from mortgaging,  pledging or subjecting to any
lien any  property  or assets,  whether or not  acquired by such person from the
Company.

           Notwithstanding  the  foregoing,  the  Company  and any  Gas  Utility
Subsidiary may create,  incur or permit to exist any lien to secure Indebtedness
in addition to those permitted by the preceding paragraph,  and renew, extend or
replace  such liens,  PROVIDED  that at the time of such  creation,  incurrence,
renewal,  extension or replacement,  after giving effect thereto,  the aggregate
amount of all such Indebtedness of the Company and the Gas Utility  Subsidiaries
and the aggregate  Attributable Value of all Sale and Leaseback  Transactions of
the  Company  and the Gas  Utility  Subsidiaries  at any  one  time  outstanding
together shall not exceed 10% of Consolidated Tangible Assets.

Section 1008.                  SALE AND LEASEBACK TRANSACTIONS

           Neither the Company nor any Gas Utility Subsidiary may enter into any
Sale  and  Leaseback   Transaction   unless  either  (1)  the  Company  and  its
Subsidiaries  would be entitled pursuant to Section 1007 to create  Indebtedness
secured by a lien on the Principal Property to be leased back in an amount equal
to the  Attributable  Value of such Sale and Leaseback  Transaction  without the
debt  securities  being  equally and ratably  secured with (or, at the Company's
option,  prior to) that  Indebtedness;  or (2) the Company or the  relevant  Gas
Utility  Subsidiary,  within 270 days after the sale or transfer of the relevant
assets  shall have been made,  applies,  in the case of a sale or  transfer  for
cash,  an amount  equal to the net  proceeds  from the sale or, in the case of a
sale or transfer  otherwise  than for cash,  an amount  equal to the fair market
value of the Principal Property so leased (as determined by any two directors of
our company or the relevant Gas Utility  Subsidiary)  to (A) the  retirement  of
Indebtedness  of the  Company  ranking  prior  to or on a  parity  with the debt
securities,  incurred or assumed by us or that Gas Utility Subsidiary,  which by
its terms matures at, or is extendible or renewable at the option of the obligor
to, a date more than  twelve  months  after the date of  incurring,  assuming or
guaranteeing such  Indebtedness or (B) the investment in any Principal  Property
used in the ordinary course of business.

Section 1009.                  WAIVER OF CERTAIN COVENANTS.

           The  Company may omit in any  particular  instance to comply with any
covenant or condition set forth in Sections 1004 to 1009,  inclusive,  if before
or after the time for such  compliance the Holders of more than 50% in principal
amount of the  Outstanding  Securities of each series of Securities  affected by
the  omission  shall,  in each case by Act of such  Holders,  either  waive such
compliance in such instance or generally waive  compliance with such covenant or
condition,  but no such  waiver  shall  extend to or  affect  such  covenant  or
condition except to the extent so expressly waived, and, until such waiver shall
become  effective,  the obligations of the Company and the duties of the Trustee
for the Securities of each series with respect to any such covenant or condition
shall remain in full force and effect.

Section 1010.                  PAYMENT OF ADDITIONAL AMOUNTS.

                                                             64

<PAGE>



           If specified  pursuant to Section 301, the provisions of this Section
1010 shall be applicable to Securities of any series.

           The Company will, subject to the exceptions and limitations set forth
below,  pay to the Holder of any Security or coupon who is a United States Alien
such  additional  amounts as may be  necessary so that every net payment on such
Security or coupon,  after deduction or withholding by the Company or any of its
Paying  Agents for or on account of any  present or future  tax,  assessment  or
other  governmental  charge  imposed  upon or as a result of such payment by the
United  States (or any  political  subdivision  or taxing  authority  thereof or
therein),  will not be less than the amount provided in such Security or in such
coupon to be then due and payable.  However, the Company will not be required to
make any payment of additional amounts for or on account of:

           (a) any tax,  assessment or other governmental  charge that would not
have  been so  imposed  but  for (i) the  existence  of any  present  or  former
connection  between such Holder (or between a fiduciary,  settler or beneficiary
of, or a person holding a power over,  such Holder,  if such Holder is an estate
or  trust,  or a member  or  shareholder  of such  Holder,  if such  Holder is a
partnership  or  corporation)   and  the  United  States,   including,   without
limitation, such Holder (or such fiduciary, settler, beneficiary, person holding
a power,  member or  shareholder)  being or having  been a citizen,  resident or
treated  as a  resident  thereof  or being or having  been  engaged  in trade or
business or present  therein or having or having had a  permanent  establishment
therein,  or (ii) such Holder's  present or former status as a personal  holding
company,  foreign personal holding company,  controlled  foreign  corporation or
passive  foreign  investment  company with respect to the United  States or as a
corporation that accumulates earnings to avoid United States federal income tax;

           (b) any tax,  assessment or other governmental charge which would not
have been so imposed but for the  presentation by the Holder of such Security or
coupon  for  payment  on a date more than 10 days  after the date on which  such
payment  became  due and  payable or the date on which  payment  thereof is duly
provided for, whichever occurs later;

          (c) any estate, inheritance,  gift, sales, transfer, personal property
     tax or any similar tax, assessment or other governmental charge;

           (d) any tax,  assessment or other governmental  charge required to be
withheld  by any Paying  Agent from any  payment in respect of any  Security  or
coupon,  if such payment can be made without  such  withholding  by at least one
other Paying Agent;

          (e) any tax,  assessment or other governmental charge which is payable
     otherwise than by withholding  from payments in respect of such Security or
     coupon;

           (f) any tax,  assessment or other  governmental  charge  imposed on a
Holder of a Security or coupon that actually or  constructively  owns 10 percent
or more of the  total  combined  voting  power  of all  classes  of stock of the
Company entitled to vote within the meaning of Section  871(h)(3) of the Code or
that is a controlled  foreign  corporation  related to the Company through stock
ownership;

           (g) any tax,  assessment or other  governmental  charge  imposed as a
result of the  failure to comply  with  applicable  certification,  information,
documentation  or  other  reporting  requirements  concerning  the  nationality,
residence,  identity  or  connection  with the  United  States of the  Holder or
beneficial  owner of a Security  or coupon,  if such  compliance  is required by
statute or by regulation of the United States,  as a  precondition  to relief or
exemption from such tax, assessment or other governmental charge;

                                                             65

<PAGE>



           (h) any tax,  assessment or other  governmental  charge  imposed with
respect to payments on any  Registered  Security by reason of the failure of the
Holder to fulfill the statement  requirement of Sections 871(h) or 881(c) of the
Code; or

           (i) any  combination  of items (a),  (b), (c), (d), (e), (f), (g) and
(h); nor will additional amounts be paid with respect to any payment on any such
Security or coupon to a Holder who is a fiduciary or  partnership  or other than
the sole  beneficial  owner of such payment to the extent such payment  would be
required by the laws of the United States (or any political subdivision thereof)
to be included in the income for federal income tax purposes of a beneficiary or
settler with  respect to such  fiduciary  or a member of such  partnership  or a
beneficial  owner who would not have been entitled to payment of the  additional
amounts had beneficiary,  settler, member or beneficial owner been the Holder of
such Security or coupon.

           The term "United  States Alien" means any  corporation,  partnership,
individual or fiduciary that is, as to the United States, a foreign corporation,
a nonresident alien individual,  a nonresident  fiduciary of a foreign estate or
trust,  or a foreign  partnership  one or more of the members of which is, as to
the United States, a foreign  corporation,  a nonresident  alien individual or a
nonresident fiduciary of a foreign estate or trust.

           Whenever in this Indenture  there is mentioned,  in any context,  the
payment of the principal of (and premium,  if any) and interest,  if any, on any
Security or payment with respect to any coupon of any series, such mention shall
be deemed to include mention of the payment of additional  amounts  provided for
in the terms of such  Securities  and this Section to the extent  that,  in such
context,  additional  amounts are,  were or would be payable in respect  thereof
pursuant to the provisions of this Section and express mention of the payment of
additional  amounts  (if  applicable)  in any  provisions  hereof  shall  not be
construed as excluding  additional amounts in those provisions hereof where such
express mention is not made.

           If the  Securities of a series  provide for the payment of additional
amounts as contemplated by Section 301(20),  at least 10 days prior to the first
Interest  Payment  Date with  respect to that  series of  Securities  (or if the
Securities  of that series will not bear interest  prior to maturity,  the first
day on which a payment of  principal  and any premium is made),  and at least 10
days  prior to each date of  payment  of  principal  (and  premium,  if any) and
interest,  if any, if there has been any change with  respect to the matters set
forth in the below mentioned Officers' Certificate, the Company will furnish the
Trustee for that series of Securities and the Company's  principal  Paying Agent
or Paying  Agents,  if other than such  Trustee,  with an Officers'  Certificate
instructing  such  Trustee and such Paying Agent or Paying  Agents  whether such
payment of  principal  of (and  premium,  if any) and  interest,  if any, on the
Securities  of that series shall be made to Holders of Securities of that series
or any related  coupons who are United States Aliens without  withholding for or
on account of any tax, assessment or other governmental charge referred to above
or described in the Securities of that series.  If any such withholding shall be
required,  then such Officers'  Certificate shall specify by country the amount,
if any,  required to be withheld on such  payments to such Holders of Securities
or coupons and the Company will pay to the Trustee for such series of Securities
or such Paying Agent such additional  amounts as may be required pursuant to the
terms applicable to such series.  The Company covenants to indemnify the Trustee
for such  series  of  Securities  and any  Paying  Agent  for,  and to hold them
harmless against,  any loss,  liability or expense  reasonably  incurred without
gross negligence or bad faith on their part arising out of or in connection with

                            REDEMPTION OF SECURITIES
                            ------------------------

Section 1101.                  APPLICABILITY OF THIS ARTICLE.

           Redemption  of  Securities  of any series  (whether by operation of a
sinking  fund or  otherwise)  as  permitted  or required by any form of Security
issued  pursuant to this Indenture shall be made in accordance with such form of
Security and this Article; PROVIDED,  HOWEVER, that if any provision of any such
form of  Security  shall  conflict  with  any  provision  of this  Article,  the
provision of such form of Security shall govern.

Section 1102.                  ELECTION TO REDEEM; NOTICE TO TRUSTEE.

           The  election of the Company to redeem any  Securities  of any series
shall  be  evidenced  by or  pursuant  to a  Board  Resolution.  In  case of any
redemption at the election of the Company of less than all of the  Securities of
any  particular  series,  the  Company  shall,  at  least  60 days  prior to the
Redemption  Date  fixed  by the  Company  (unless  a  shorter  notice  shall  be
satisfactory  to the  Trustee for the  Securities  of such  series)  notify such
Trustee by Company Request of such  Redemption Date and of the principal  amount
of  Securities  of that series to be redeemed and shall  deliver to such Trustee
such  documentation  and  records  as shall  enable  such  Trustee to select the
Securities  to be  redeemed  pursuant  to  Section  1103.  In  the  case  of any
redemption  of  Securities  of  any  series  prior  to  the  expiration  of  any
restriction  on such  redemption  provided  in the terms of such  Securities  or
elsewhere  in  this  Indenture,  the  Company  shall  furnish  the  Trustee  for
Securities of such series with an Officers'  Certificate  evidencing  compliance
with such restriction.

Section 1103.                 SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

           If less than all the Securities  are to be redeemed,  the Company may
select the series to be  redeemed,  and if less than all the  Securities  of any
series  are to be  redeemed,  the  particular  Securities  of that  series to be
redeemed shall be selected not more than 60 days prior to the Redemption Date by
the Trustee for the Securities of such series,  from the Outstanding  Securities
of that  series not  previously  called for  redemption,  by such method as such
Trustee shall deem fair and  appropriate and which may provide for the selection
for redemption of portions  (equal to the minimum  authorized  denomination  for
Securities of that series,  or any integral  multiple  thereof) of the principal
amount of  Securities of that series of a  denomination  larger than the minimum
authorized denomination for Securities of that series pursuant to Section 302 in
the  currency  or  currency  unit in which the  Securities  of such  series  are
denominated.

           The Trustee  for the  Securities  of any series to be redeemed  shall
promptly notify the Company in writing of the Securities of such series 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  Security  redeemed  or to be redeemed  only in part,  to the
portion of the principal  amount of such  Securities  which has been or is to be
redeemed.

Section 1104.                  NOTICE OF REDEMPTION.

           Notice of redemption shall be given in the manner provided in Section
106 not later than the thirtieth day and not earlier than the sixtieth day prior
to the Redemption Date, to each Holder of Securities to be redeemed.

                                                             67

           All notices of redemption shall state:

                     (1)       the Redemption Date,

                     (2)       the Redemption Price,

                     (3) if less than all Outstanding Securities of a particular
           series are to be redeemed,  the  identification  (and, in the case of
           partial  redemption,   the  respective   principal  amounts)  of  the
           particular  Securities to be redeemed,  including the CUSIP number of
           such Securities,

                     (4) that on the Redemption  Date the Redemption  Price will
           become due and payable  upon each such  Security or portion  thereof,
           and that interest thereon,  if any (or in the case of OID Securities,
           original  issue  discount),  shall  cease to accrue on and after said
           date,

                     (5) 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,

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

                    (7) 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 or security or
               indemnity  satisfactory  to the  Company,  the  Trustee  for such
               series and any Paying Agent is furnished, and

                     (8) if Bearer  Securities  of any series are to be redeemed
           and any Registered  Securities of such series are not to be redeemed,
           and if  such  Bearer  Securities  may  be  exchanged  for  Registered
           Securities not subject to redemption on this Redemption Date pursuant
           to Section 305 or  otherwise,  the last date,  as  determined  by the
           Company, on which such exchanges may be made.

           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 for such Securities in the name and at the expense of the Company.

Section 1105.                  DEPOSIT OF REDEMPTION PRICE.

           Prior to the opening of business on any Redemption  Date, the Company
shall  deposit  with the  Trustee  for the  Securities  to be redeemed or with a
Paying Agent for such Securities (or, if the Company is acting as its own Paying
Agent for such  Securities,  segregate  and hold in trust as provided in Section
1003)  an  amount  of money  in the  currency  or  currency  unit in  which  the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such Series and except as provided in Sections
311(b) and 311(d))  sufficient to pay the principal  amount of (and premium,  if
any,  thereon),  and (except if the Redemption Date shall be an Interest Payment
Date) any accrued  interest on, all the  Securities  which are to be redeemed on
that date.

Section 1106.                  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

                                                             68

specified  in the  currency or  currency  unit in which the  Securities  of such
series are payable (except as otherwise provided pursuant to Section 301 for the
Securities of such series and except as provided in Sections  311(b) and 311(d))
and from and after such date (unless the Company shall default in the payment of
the  Redemption  Price) 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
such Security for  redemption in accordance  with said notice  together with all
coupons, if any,  appertaining  thereto maturing after the Redemption Date, such
Security  or  specified  portions  thereof  shall be paid by the  Company at the
Redemption  Price;  PROVIDED,  HOWEVER,  that installments of interest on Bearer
Securities  whose Stated Maturity is on or prior to the Redemption Date shall be
payable only at an office or agency located outside the United States (except as
otherwise  provided  in  Section  1002)  and,  unless  otherwise   specified  as
contemplated by Section 301, only upon presentation and surrender of coupons for
such  interest,  and  PROVIDED,  FURTHER,  that unless  otherwise  specified  as
contemplated by Section 301,  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  relevant  Record  Dates
according to their terms and the provisions of Section 307.

           If any  Bearer  Security  surrendered  for  redemption  shall  not be
accompanied by all coupons  appertaining  thereto  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  if there is
furnished  to the  Company,  the Trustee for such  Security and any Paying Agent
such security or indemnity as they may require to save the Company, such Trustee
and any Paying Agent  harmless.  If thereafter the Holder of such Security shall
surrender to such 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
interest  represented  by coupons  shall be payable  only at an office or agency
located outside the United States (except as otherwise provided in Section 1002)
and,  unless  otherwise  specified as  contemplated  by Section  301,  only upon
presentation and surrender of those coupons.

           If any  Security  called  for  redemption  shall  not be so paid upon
surrender thereof for redemption,  the principal  thereof (and premium,  if any,
thereon) shall, until paid, bear interest from the Redemption Date at a rate per
annum  equal  to the  rate  borne by the  Security  (or,  in the case of (i) OID
Securities,  the Security's  Yield to Maturity or (ii) Indexed  Securities,  the
rate determined in accordance with the specified terms of those Securities).

Section 1107.                  SECURITIES REDEEMED IN PART.

           Any Registered Security which is to be redeemed only in part shall be
surrendered  at the Place of Payment  (with,  if the  Company or the Trustee for
such  Security so  requires,  due  endorsement  by, or 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),  and the Company  shall  execute and such Trustee shall
authenticate  and deliver to the Holder of such Security without service charge,
a new Registered  Security or  Securities,  of any  authorized  denomination  as
requested  by such  Holder,  of the same  series  and  having the same terms and
provisions and in an aggregate principal amount equal to and in exchange for the
unredeemed  portion of the principal of the Registered  Security so surrendered.

Section 1108. TAX REDEMPTION; SPECIAL TAX REDEMPTION.

           (a) Unless otherwise specified pursuant to Section 301, Securities of
any series may be  redeemed  at the option of the  Company in whole,  but not in
part,  on not more  than 60  days'  and not less  than 30 days'  notice,  on any
Redemption Date at the Redemption Price specified

                                                             69

pursuant to Section 301, if the Company  determines  that (A) as a result of any
change in or amendment to the laws (or any  regulations  or rulings  promulgated
thereunder)  of the  United  States or of any  political  subdivision  or taxing
authority  thereof  or therein  affecting  taxation,  or any change in  official
position  regarding  application or interpretation of such laws,  regulations or
rulings (including a holding by a court of competent  jurisdiction in the United
States), which change or amendment is announced or becomes effective on or after
a date specified in Section 301 with respect to any Security of such series, the
Company has or will  become  obligated  to pay  additional  amounts  pursuant to
Section  1011 with  respect to any  Security of such series or (B) on or after a
date  specified in Section 301 with respect to any Security of such series,  any
action has been  taken by any  taxing  authority  of, or any  decision  has been
rendered  by a court of  competent  jurisdiction  in, the  United  States or any
political  subdivision or taxing authority thereof or therein,  including any of
those  actions  specified in (A) above,  whether or not such action was taken or
decision was rendered  with  respect to the Company,  or any change,  amendment,
application or interpretation shall be officially  proposed,  which, in any such
case,  in the  Opinion  of  Counsel  to the  Company  will  result in a material
probability  that the Company will become  obligated to pay  additional  amounts
with respect to any Security of such series,  and (C) in any such case specified
in (A) or (B) above the Company, in its business judgment,  determines that such
obligation cannot be avoided by the use of reasonable  measures available to the
Company.

           (b)  Unless  otherwise  specified  pursuant  to Section  301,  if the
Company shall  determine  that any payment made outside the United States by the
Company or any of their Paying Agents of principal or interest due in respect of
any  Bearer  Security  (an  "Affected  Security")  of such  series or any coupon
appertaining  thereto would,  under any present or future laws or regulations of
the  United  States,  be  subject  to any  certification,  information  or other
reporting  requirement  of any  kind,  the  effect of which  requirement  is the
disclosure to the Company, any Paying Agent or any governmental authority of the
nationality,  residence or identity (as distinguished from, for example,  status
as a United  States Alien) of a beneficial  owner of such  Affected  Security of
such  series  or  coupon  that is a  United  States  Alien  (other  than  such a
requirement  that (i) would not be  applicable to a payment made by the Company,
or any one of their Paying Agents (A) directly to the beneficial owner or (B) to
a  custodian,  nominee  or other  agent  of the  beneficial  owner,  (ii) can be
satisfied by such  custodian,  nominee or other agent  certifying  to the effect
that such beneficial owner is a United States Alien; provided that, in each case
referred to in clauses  (i)(B) or (ii),  payment by such  custodian,  nominee or
other  agent to such  beneficial  owner  is not  otherwise  subject  to any such
requirement  (other than a requirement which is imposed on a custodian,  nominee
or other  agent  described  in item (iv) of this  sentence),  (iii) would not be
applicable  to a payment  made by at least one other Paying Agent of the Company
or (iv) is applicable to a payment to a custodian, nominee or other agent of the
beneficial  owner of such Security who is a United States person (as hereinafter
defined),  a controlled  foreign  corporation for United States tax purposes,  a
foreign  person  50  percent  or more  of the  gross  income  of  which  for the
three-year  period ending with the close of its taxable year  preceding the year
of payment is effectively  connected with a United States trade or business,  or
is otherwise related to the United States), the Company shall elect by notice to
the  Trustee  for such series of  Securities  either (x) to redeem the  Affected
Securities  of such  series,  as a whole,  at a  redemption  price  equal to the
principal  amount thereof,  together with interest accrued to the date fixed for
redemption,  or (y) if the  conditions  of the  next  succeeding  paragraph  are
satisfied,  to pay the  additional  amounts  specified  in such  paragraph.  The
Company shall make such  determination  and election as soon as practicable  and
give prompt notice thereof (the "Determination  Notice") in the manner described
in Section 106 stating the effective date of such certification,  information or
reporting  requirement,  whether the Company has elected to redeem the  Affected
Securities of such series or to pay the additional amounts specified in the next
succeeding paragraph,  and (if applicable) the last date by which the redemption
of the Affected  Securities  of such series must take place,  as provided in the
next  succeeding  sentence.  If  the  Company  elects  to  redeem  the  Affected
Securities of such series,  such  redemption  shall take place on such date, not
later than one year after the giving of the Determination Notice, as the Company
shall  specify by notice to such Trustee given not less than 45 nor more than 75
days

                                                             70

before the Redemption Date. Notice of such redemption of the Affected Securities
of such series  shall be given to the Holders  thereof not less than 30 days nor
more than 60 days prior to the Redemption Date.  Notwithstanding  the foregoing,
the Company  shall not so redeem the Affected  Securities  of such series if the
Company shall subsequently  determine by notice to the Trustee, not less than 30
days prior to the  Redemption  Date,  that  subsequent  payments on the Affected
Securities  of such  series  would  not be  subject  to any such  certification,
information or other reporting requirement, in which case the Company shall give
prompt  notice of such  subsequent  determination  in the  manner  specified  in
Section  106 and any  earlier  redemption  notice  shall be revoked and be of no
further  effect.  The right of the  Holders of  Affected  Securities  called for
redemption to exchange such Affected Securities for Registered Securities (which
Registered  Securities will remain  Outstanding  following such redemption) will
terminate on the  fifteenth  day prior to the  Redemption  Date,  and no further
exchanges of Affected  Securities for Registered  Securities  shall be permitted
unless the Company shall have made the  subsequent  determination  and given the
notice  referred to in the  preceding  sentence.  As used  hereinabove,  "United
States  person"  means  any  citizen  or  resident  of the  United  States,  any
corporation,  partnership  or other entity  created or organized in or under the
laws of the United States and any estate or trust the income of which is subject
to United States federal income taxation regardless of its source.

           If and so long as the  certification,  information or other reporting
requirement  referred to in the preceding  paragraph would be fully satisfied by
payment of a withholding  tax, backup  withholding  tax or similar  charge,  the
Company may elect by notice to the Trustee to pay such additional amounts as may
be necessary so that every net payment made outside the United States  following
the  effective  date of such  requirement  by the Company or any of their Paying
Agents of principal (or premium, if any) or interest,  if any, due in respect of
any  Affected  Security of such series or any coupon  appertaining  thereto to a
Holder who  certifies  that the  beneficial  owner is a United States Alien (but
without any  requirement  that the  nationality,  residence  or identity of such
beneficial  owner  be  disclosed  to  the  Company,  any  Paying  Agent  or  any
governmental  authority),  after  deduction or withholding  for or on account of
such  withholding  tax,  backup  withholding tax or similar charge (other than a
withholding tax, backup withholding tax or similar charge that (i) is the result
of a certification,  information or other reporting requirement described in the
third  parenthetical  clause of the first sentence of the preceding paragraph or
(ii) is imposed as a result of  presentation  of any such  Affected  Security or
such coupon for payment  more than 10 days after the date on which such  payment
becomes  due and payable or on which  payment  thereof  was duly  provided  for,
whichever  occurs  later),  will not be less than the  amount  provided  in such
Affected  Security or such coupon to be then due and  payable.  In the event the
Company  elects to pay such  additional  amounts,  (the  Company's  election  to
exercise  such right to be  evidenced  by prompt  notice to the  Trustee for the
Securities of the appropriate  series),  the Company will have the right, at its
sole option, at any time, to redeem the Affected  Securities of such series as a
whole,  but not in part, at the Redemption  Price,  subject to the provisions of
the last four sentences of the immediately  preceding paragraph.  If the Company
has made the determination  described in the preceding paragraph with respect to
certification,  information or other reporting  requirements  applicable only to
interest and subsequently  makes a determination in the manner and of the nature
referred  to in such  preceding  paragraph  with  respect  to such  requirements
applicable to principal, the Company will redeem the Affected Securities of such
series in the  manner  and on the terms  described  in the  preceding  paragraph
unless the Company elects to have the provisions of this paragraph  apply rather
than  the  provisions  of  the  immediately  preceding  paragraph.  If  in  such
circumstances  the Affected  Securities  of such series are to be redeemed,  the
Company  shall have no  obligation to pay  additional  amounts  pursuant to this
paragraph with respect to principal (or premium, if any) or interest accrued and
unpaid  after  the date of the  notice  of such  determination  indicating  such
redemption, but will be obligated to pay such additional amounts with respect to
interest  accrued and unpaid to the date of such  determination.  If the Company
elects to pay  additional  amounts  pursuant to this paragraph and the condition
specified in the first sentence of this paragraph should no longer be satisfied,
then the Company shall promptly redeem the Affected Securities

                                                             71

<PAGE>



of such series in whole, but not in part, at the Redemption Price subject to the
provisions of the last four sentences of the immediately preceding paragraph. If
the Company elects to, or is required to, redeem the Affected Securities of such
series  pursuant to this  paragraph,  it shall  publish in the manner and to the
extent provided in Section 106 prompt notice thereof. If the Affected Securities
of such series are to be redeemed  pursuant to this  paragraph,  the  redemption
shall take place on such date, not later than one year after  publication of the
notice of redemption,  as the Company shall specify by notice to the Trustee for
such series of Securities  at least 60 days prior to the  Redemption  Date.  Any
redemption  payments  made by the Company  pursuant to this  paragraph  shall be
subject to the continuing  obligation of the Company to pay  additional  amounts
pursuant to this paragraph.

                                  SINKING FUNDS
                                  -------------

Section 1201.                  APPLICABILITY OF THIS ARTICLE.

           Redemption  of  Securities  through  operation  of a sinking  fund as
permitted or required by any form of Security  issued pursuant to this Indenture
shall be made in  accordance  with  such  form of  Security  and  this  Article;
PROVIDED,  HOWEVER,  that if any  provision  of any such form of Security  shall
conflict  with any  provision  of this  Article,  the  provision of such form of
Security shall govern.

           The minimum  amount of any sinking fund  payment  provided for by the
terms  of  Securities  of any  particular  series  is  herein  referred  to as a
"mandatory  sinking  fund  payment",  and any payment in excess of such  minimum
amount  provided  for by the terms of  Securities  of any  particular  series is
herein referred to as an "optional sinking fund payment". If provided for by the
terms of Securities  of any  particular  series,  the cash amount of any sinking
fund  payment may be subject to  reduction  as provided  in Section  1202.  Each
sinking fund payment  shall be applied to the  redemption  of  Securities of any
particular series as provided for by the terms of Securities of that series.

Section 1202.            SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

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

Section 1203.                  REDEMPTION OF SECURITIES FOR SINKING FUND.

           Not less than 60 days prior to each sinking fund payment date for any
particular series of Securities, the Company will deliver to the Trustee for the
Securities of such series an Officers' 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 in the currency or currency unit in which the Securities of that
series are payable

                                                             72

(except as otherwise  specified  pursuant to Section 301 for the  Securities  of
that  series and except as  provided  in  Sections  311(b) and  311(d))  and the
portion  thereof,  if any,  which is to be satisfied by delivering and crediting
Securities of that series pursuant to Section 1202 and shall state the basis for
such credit and that such  Securities  have not previously  been so credited and
will also  deliver to such  Trustee  any  Securities  to be so  delivered.  Such
Trustee  shall  select the  Securities  to be redeemed  upon such  sinking  fund
payment  date in the manner  specified  in Section  1103 and cause notice of the

whether  or  not  present  or   represented   at  the  meeting.

Section  1305.  DETERMINATION OF VOTING RIGHTS; CONDUCT AND ADJOURNMENT OF

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  104 and the
appointment of any proxy shall be proved in the manner  specified in Section 104
or by having  the  signature  of the person  executing  the proxy  witnessed  or
guaranteed  by any trust  company,  bank or banker  authorized by Section 104 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 104 or other proof.

           (b) The Trustee for any series of  Securities  that  includes  Bearer
Securities 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 1302(b),  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

entitled to vote a majority in principal amount of the Outstanding Securities of
such series represented at the meeting.

           (c) 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 as determined in accordance  with Section
115; 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.

           (d) Any  meeting of holders of  Securities  of any series duly called
pursuant to Section 1302 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  1306.      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
duplicate,  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  1302  and,  if
applicable,  Section  1304.  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 for such
series  of  Securities  to be  preserved  by such  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.

               (whether or not also  described  in clause (i) or (ii)),  further
               certify that they have not acquired  the  beneficial  interest in
               the temporary  Global Security for the purpose of resale directly
               or indirectly to a United States person or to a person within the

CERTIFICATE OF AUTHENTICATION

This is one of the Securities of the series designated  therein described in the
within-mentioned Indenture.

THE CHASE MANHATTAN BANK,
    as Trustee


By:______________________________
     Authorized Officer

                                (Reverse of Note)

                               KEYSPAN CORPORATION

     This Note is one of a duly  authorized  issue of  Securities of the Company
designated  as its 7.25% Notes Due 2005 (the  "Notes").  The Notes are one of an
indefinite   number  of  series  of  debt   securities   of  the  Company   (the
"Securities"),  issued or  issuable  under and  pursuant  to an  indenture  (the
"Indenture")  dated as of  November  1, 2000,  between the Company and The Chase
Manhattan Bank (herein  called the "Trustee,"  which term includes any successor
Trustee under the Indenture), to which Indenture and all indentures supplemental

                                                             3

<PAGE>



thereto  reference  is hereby  made for a  statement  of the  respective  rights
thereunder  of the  Company,  the  Trustee  and the Holders of the Notes and the
terms upon which the Notes are to be authenticated  and delivered.  This Note is
one of a series  designated on the face hereof as limited (except as provided in
the Indenture) in aggregate principal amount to $700,000,000. The terms of other
series of  Securities  issued  under the  Indenture  may vary  with  respect  to
interest rates or interest rate  formulas,  issue dates,  maturity,  redemption,
repayment,  currency of payment and otherwise as provided in the Indenture.  The
Indenture  further  provides that Securities of a single series may be issued at
various times, with different  maturity dates and may bear interest at different
rates.
                     This Note is not subject to any sinking fund.

     If an Event of Default (other than an Event of Default described in Section
501 (5) or 501(6) of the Indenture) with respect to the Notes shall occur and be
continuing,  then  either  the  Trustee  or the  Holders of not less than 25% in
aggregate  principal  amount of the Notes of this  series then  Outstanding  may
declare  the  aggregate  principal  amount of the Notes of this  series  due and
payable in the manner and with the effect provided in the Indenture. If an Event
of Default  specified  in Section  501(5) or 501(6)  occurs with  respect to the
Company,  all of the unpaid  principal amount and accrued interest thereon shall
ipso facto become and be immediately  due and payable in the manner and with the
effect  provided in the Indenture  without any  declaration  or other act by the
Trustee or any Holder.

     This Note may be redeemed in whole at any time at the option of the Company
(such  date of  redemption,  the  "Optional  Redemption  Date") at the  Optional
Redemption  Price (as defined below)  together with interest  accrued thereon to
the Optional  Redemption Date, on notice given not more than 60 nor less than 30
days prior to the Optional Redemption Date.

     The "Optional Redemption Price" shall equal the sum of the principal amount
of the Note and the Make Whole Amount (as defined  below).  "Make-Whole  Amount"
means,  the excess,  if any, of the  aggregate  present value as of the Optional
Redemption  Date  of  principal  being  redeemed  and  the  amount  of  interest
(exclusive of interest accrued to the Optional  Redemption Date) that would have
been payable if redemption had not been made,  determined by  discounting,  on a
semiannual basis, the remaining  principal and interest at the Reinvestment Rate
(as defined  below)  (determined  on the third  Business Day  preceding the date
notice of  redemption  is  given)  from the  dates on which  the  principal  and
interest  would have been payable if the  redemption  had not been made,  to the
Optional Redemption Date, over the aggregate principal amount of the Notes being
redeemed.

     "Reinvestment  Rate" shall mean 25 basis points plus the arithmetic mean of
the  yield  under  the  heading  "Week  Ending"  published  in the  most  recent
Statistical  Release under the caption  "Treasury  Constant  Maturities" for the
maturity  (rounded to the nearest month)  corresponding to the remaining life to
maturity,  as of the payment date of the principal being redeemed or paid. If no
maturity  exactly  corresponds  to the  maturity,  yields for the two  published
maturities most closely corresponding to the maturity shall be so calculated and
the  Reinvestment  Rate shall be interpolated or extrapolated on a straight-line
basis,  rounding  to the nearest  month.  The most  recent  Statistical  Release
published prior to the date of determination  of the Make-Whole  Amount shall be
used for purposes of calculating the Reinvestment Rate.

     The  Make-Whole  Amount shall be  calculated by an  independent  investment
banking  institution  of national  standing  appointed  by the  Company.  If the
Company  fails to make the  appointment  at least 45 business  days prior to the
Optional  Redemption  Date, or if the institution is unwilling or unable to make
the  calculation,  the  calculation  shall be made by an independent  investment
banking  institution  of national  standing  appointed  by the  Trustee.  If the
Reinvestment  Rate is not available as described above,  the  Reinvestment  Rate
shall be calculated

                                                             4

by   interpolation   or  extrapolation  of  comparable  rates  selected  by  the
independent investment
banking institution.

     The Indenture  permits,  with certain  exceptions as therein provided,  the
Company  and the  Trustee  with the  consent of the  Holders of more than 50% in
principal amount of the Securities at the time Outstanding of each series issued
under the Indenture to be affected thereby, to execute  supplemental  indentures
for the  purpose  of adding  any  provisions  to or  changing  in any  manner or
eliminating any of the provisions of the Indenture or of modifying in any manner
the rights of the Holders of the Securities of such series;  PROVIDED,  HOWEVER,
that no such supplemental  indenture shall,  among other things,  (i) change the
Stated  Maturity of the  principal  of, or any  installment  of  principal of or
interest on, any Security,  or reduce the principal  amount  thereof or interest
thereon,  if any, or any premium payable upon redemption thereof, or (ii) change
the Place of Payment on any Security or the  currency or currency  unit in which
any Security or the principal or interest  thereon is payable;  impair the right
to institute suit for the enforcement of any such payment on or after the Stated
Maturity  thereof;  or reduce or alter the method of  computation  of any amount
payable upon redemption,  repayment or purchase of any Securities by the Company
(or the time when such redemption, repayment or purchase may be made); or reduce
the percentage in principal  amount of the Securities,  the Holders of which are
required to consent to any  supplemental  indenture,  without the consent of the
Holder of each Security affected thereby. The Indenture also contains provisions
permitting the Holders of more than 50% in principal amount of the Securities of
each  series  at the time  outstanding,  on  behalf  of the  Holders  of all the
Securities  of that  series,  to waive  compliance  by the Company  with certain
provisions of the  Indenture  and certain past defaults  under the Indenture and
their consequences with respect to such series,  except a default in the payment
of principal of or interest, if any, on any Security of that series or a default
with respect to a covenant or provision of the Indenture which cannot be amended
without the consent of such Holder.

     The  Notes  are  issuable  only  in  registered  form  without  coupons  in
denominations  of $1,000 and  integral  multiples  thereof.  As  provided in the
Indenture and subject to certain  limitations  therein set forth,  the Notes are
exchangeable for a like aggregate  principal amount of Notes as requested by the
Holder  surrendering the same. If (x) the Depositary is at any time unwilling or
unable to continue as depository and a successor  depository is not appointed by
the  Company  within 90 days after the Company  receives  such notice or becomes
aware of such  ineligibility,  (y) the Company delivers to the Trustee a Company
Order to the  effect  that this Note  shall be  exchangeable  or (z) an Event of
Default has occurred  and is  continuing  with  respect to the Notes,  this Note
shall be  exchangeable  for Notes in definitive  form and in an equal  aggregate
principal  amount.  Such  definitive  Notes shall be  registered in such name or
names as the Depositary shall instruct the Trustee.

     As provided in the Indenture and subject to certain  limitations  set forth
therein and above,  the transfer of this Note may be  registered on the Security
Register  of the  Company,  upon  surrender  of this  Note for  registration  of
transfer at the office or agency of the Company in the Borough of Manhattan, The
City of New York,  duly endorsed by, or accompanied  by a written  instrument of
transfer in form satisfactory to the Company duly executed by, the Holder hereof
or by his attorney  duly  authorized  in writing,  and thereupon one or more new
Notes of authorized  denominations  and for the same aggregate  principal amount
will be issued to the designated transferee or transferees.

     No reference  herein to the  Indenture  and no provision of this Note or of
the  Indenture  shall alter or impair the  obligation  of the Company,  which is
absolute and  unconditional,  to pay the principal of (and premium,  if any) and
interest on this Note at the time,  place and rate, and in the coin or currency,
herein and in the Indenture prescribed.

<PAGE>



     No service  charge shall be made for any such  registration  of transfer or
exchange,  but the Company may require  payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

     Prior to due  presentment of this Note for  registration  of transfer,  the
Company,  the  Trustee and any agent of the Company or the Trustee may treat the
Person in whose  name  this  Note is  registered  as the  owner  hereof  for all
purposes,  whether or not this Note be overdue,  and neither  the  Company,  the
Trustee nor any such agent shall be affected by notice to the contrary.

     Certain of the Company's  obligations  under the Indenture  with respect to
Notes,  may be terminated if the Company  irrevocably  deposits with the Trustee
money or  Government  Obligations  sufficient  to pay and  discharge  the entire
indebtedness on all Notes, as provided in the Indenture.

     No recourse  shall be had for the payment of the principal of (and premium,
if any), or the interest,  if any, on this Note, or for any claim based thereon,
or upon any  obligation,  covenant or agreement of the Company in the Indenture,
against the any incorporator,  stockholder,  officer or director, as such, past,
present of future,  of the Company or of any successor  corporation,  whether by
virtue of any constitution,  statute or rule of law or by the enforcement of any
assessment of penalty or otherwise; and all such personal liability is expressly
released and waived as a condition of, and as part of the consideration for, the
issuance of this Note.

     The  Indenture  and  the  Notes  shall  be  governed  by and  construed  in
accordance with the laws of the State of New York.

     All terms used in this Note which are defined in the  Indenture  shall have
the meanings assigned to them in the Indenture.

By:______________________________
     Authorized Officer

                                (Reverse of Note)

                               KEYSPAN CORPORATION

     This Note is one of a duly  authorized  issue of  Securities of the Company
designated as its 7.625% Notes Due 2010 (the  "Notes").  The Notes are one of an
indefinite   number  of  series  of  debt   securities   of  the  Company   (the
"Securities"), issued or issuable under

                                                             3

and pursuant to an  indenture  (the  "Indenture")  dated as of November 1, 2000,
between the Company and The Chase  Manhattan  Bank (herein called the "Trustee,"
which  term  includes  any  successor  Trustee  under the  Indenture),  to which
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective  rights  thereunder of the Company,  the Trustee and
the  Holders  of the  Notes  and  the  terms  upon  which  the  Notes  are to be
authenticated and delivered. This Note is one of a series designated on the face
hereof as limited  (except as provided in the Indenture) in aggregate  principal
amount to $700,000,000. The terms of other series of Securities issued under the
Indenture  may vary with respect to interest  rates or interest  rate  formulas,
issue dates, maturity, redemption,  repayment, currency of payment and otherwise
as provided in the Indenture.  The Indenture further provides that Securities of
a single series may be issued at various times,  with  different  maturity dates
and may bear interest at different rates.

                     This Note is not subject to any sinking fund.

     If an Event of Default (other than an Event of Default described in Section
501 (5) or 501(6) of the Indenture) with respect to the Notes shall occur and be
continuing,  then  either  the  Trustee  or the  Holders of not less than 25% in
aggregate  principal  amount of the Notes of this  series then  Outstanding  may
declare  the  aggregate  principal  amount of the Notes of this  series  due and
payable in the manner and with the effect provided in the Indenture. If an Event
of Default  specified  in Section  501(5) or 501(6)  occurs with  respect to the
Company,  all of the unpaid  principal amount and accrued interest thereon shall
ipso facto become and be immediately  due and payable in the manner and with the
effect  provided in the Indenture  without any  declaration  or other act by the
Trustee or any Holder.

     This Note may be redeemed in whole at any time at the option of the Company
(such  date of  redemption,  the  "Optional  Redemption  Date") at the  Optional
Redemption  Price (as defined below)  together with interest  accrued thereon to
the Optional  Redemption Date, on notice given not more than 60 nor less than 30
days prior to the Optional Redemption Date.

     The "Optional Redemption Price" shall equal the sum of the principal amount
of the Note and the Make Whole Amount (as defined  below).  "Make-Whole  Amount"
means,  the excess,  if any, of the  aggregate  present value as of the Optional
Redemption  Date  of  principal  being  redeemed  and  the  amount  of  interest
(exclusive of interest accrued to the Optional  Redemption Date) that would have
been payable if redemption had not been made,  determined by  discounting,  on a
semiannual basis, the remaining  principal and interest at the Reinvestment Rate
(as defined  below)  (determined  on the third  Business Day  preceding the date
notice of  redemption  is  given)  from the  dates on which  the  principal  and
interest  would have been payable if the  redemption  had not been made,  to the
Optional Redemption Date, over the aggregate principal amount of the Notes being
redeemed.

     "Reinvestment  Rate" shall mean 30 basis points plus the arithmetic mean of
the  yield  under  the  heading  "Week  Ending"  published  in the  most  recent
Statistical  Release under the caption  "Treasury  Constant  Maturities" for the
maturity  (rounded to the nearest month)  corresponding to the remaining life to
maturity,  as of the payment date of the principal being redeemed or paid. If no
maturity  exactly  corresponds  to the  maturity,  yields for the two  published
maturities most closely corresponding to the maturity shall be so calculated and
the  Reinvestment  Rate shall be interpolated or extrapolated on a straight-line
basis,  rounding  to the nearest  month.  The most  recent  Statistical  Release
published prior to the date of determination  of the Make-Whole  Amount shall be
used for purposes of calculating the Reinvestment Rate.

     The  Make-Whole  Amount shall be  calculated by an  independent  investment
banking  institution  of national  standing  appointed  by the  Company.  If the
Company fails to

make the appointment at least 45 business days prior to the Optional  Redemption
Date, or if the institution is unwilling or unable to make the calculation,  the
calculation shall be made by an independent  investment  banking  institution of
national  standing  appointed by the Trustee.  If the  Reinvestment  Rate is not
available as described  above,  the  Reinvestment  Rate shall be  calculated  by
interpolation  or  extrapolation of comparable rates selected by the independent
investment banking institution.

     The Indenture  permits,  with certain  exceptions as therein provided,  the
Company  and the  Trustee  with the  consent of the  Holders of more than 50% in
principal amount of the Securities at the time Outstanding of each series issued
under the Indenture to be affected thereby, to execute  supplemental  indentures
for the  purpose  of adding  any  provisions  to or  changing  in any  manner or
eliminating any of the provisions of the Indenture or of modifying in any manner
the rights of the Holders of the Securities of such series;  PROVIDED,  HOWEVER,
that no such supplemental  indenture shall,  among other things,  (i) change the
Stated  Maturity of the  principal  of, or any  installment  of  principal of or
interest on, any Security,  or reduce the principal  amount  thereof or interest
thereon,  if any, or any premium payable upon redemption thereof, or (ii) change
the Place of Payment on any Security or the  currency or currency  unit in which
any Security or the principal or interest  thereon is payable;  impair the right
to institute suit for the enforcement of any such payment on or after the Stated
Maturity  thereof;  or reduce or alter the method of  computation  of any amount
payable upon redemption,  repayment or purchase of any Securities by the Company
(or the time when such redemption, repayment or purchase may be made); or reduce
the percentage in principal  amount of the Securities,  the Holders of which are
required to consent to any  supplemental  indenture,  without the consent of the
Holder of each Security affected thereby. The Indenture also contains provisions
permitting the Holders of more than 50% in principal amount of the Securities of
each  series  at the time  outstanding,  on  behalf  of the  Holders  of all the
Securities  of that  series,  to waive  compliance  by the Company  with certain
provisions of the  Indenture  and certain past defaults  under the Indenture and
their consequences with respect to such series,  except a default in the payment
of principal of or interest, if any, on any Security of that series or a default
with respect to a covenant or provision of the Indenture which cannot be amended
without the consent of such Holder.

     The  Notes  are  issuable  only  in  registered  form  without  coupons  in
denominations  of $1,000 and  integral  multiples  thereof.  As  provided in the
Indenture and subject to certain  limitations  therein set forth,  the Notes are
exchangeable for a like aggregate  principal amount of Notes as requested by the
Holder  surrendering the same. If (x) the Depositary is at any time unwilling or
unable to continue as depository and a successor  depository is not appointed by
the  Company  within 90 days after the Company  receives  such notice or becomes
aware of such  ineligibility,  (y) the Company delivers to the Trustee a Company
Order to the  effect  that this Note  shall be  exchangeable  or (z) an Event of
Default has occurred  and is  continuing  with  respect to the Notes,  this Note
shall be  exchangeable  for Notes in definitive  form and in an equal  aggregate
principal  amount.  Such  definitive  Notes shall be  registered in such name or
names as the Depositary shall instruct the Trustee.

     As provided in the Indenture and subject to certain  limitations  set forth
therein and above,  the transfer of this Note may be  registered on the Security
Register  of the  Company,  upon  surrender  of this  Note for  registration  of
transfer at the office or agency of the Company in the Borough of Manhattan, The
City of New York,  duly endorsed by, or accompanied  by a written  instrument of
transfer in form satisfactory to the Company duly executed by, the Holder hereof
or by his attorney  duly  authorized  in writing,  and thereupon one or more new
Notes of authorized  denominations  and for the same aggregate  principal amount
will be issued to the designated transferee or transferees.

     No reference  herein to the  Indenture  and no provision of this Note or of
the  Indenture  shall alter or impair the  obligation  of the Company,  which is
absolute and  unconditional,  to pay the principal of (and premium,  if any) and
interest on this Note at the time,  place and rate, and in the coin or currency,
herein and in the Indenture prescribed.

     No service  charge shall be made for any such  registration  of transfer or
exchange,  but the Company may require  payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

     Prior to due  presentment of this Note for  registration  of transfer,  the
Company,  the  Trustee and any agent of the Company or the Trustee may treat the
Person in whose  name  this  Note is  registered  as the  owner  hereof  for all
purposes,  whether or not this Note be overdue,  and neither  the  Company,  the
Trustee nor any such agent shall be affected by notice to the contrary.

     Certain of the Company's  obligations  under the Indenture  with respect to
Notes,  may be terminated if the Company  irrevocably  deposits with the Trustee
money or  Government  Obligations  sufficient  to pay and  discharge  the entire
indebtedness on all Notes, as provided in the Indenture.

     No recourse  shall be had for the payment of the principal of (and premium,
if any), or the interest,  if any, on this Note, or for any claim based thereon,
or upon any  obligation,  covenant or agreement of the Company in the Indenture,
against the any incorporator,  stockholder,  officer or director, as such, past,
present of future,  of the Company or of any successor  corporation,  whether by
virtue of any constitution,  statute or rule of law or by the enforcement of any
assessment of penalty or otherwise; and all such personal liability is expressly
released and waived as a condition of, and as part of the consideration for, the
issuance of this Note.

     The  Indenture  and  the  Notes  shall  be  governed  by and  construed  in
accordance with the laws of the State of New York.

     All terms used in this Note which are defined in the  Indenture  shall have
the meanings assigned to them in the Indenture.

and pursuant to an  indenture  (the  "Indenture")  dated as of November 1, 2000,
between the Company and The Chase  Manhattan  Bank (herein called the "Trustee,"
which  term  includes  any  successor  Trustee  under the  Indenture),  to which
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective  rights  thereunder of the Company,  the Trustee and
the  Holders  of the  Notes  and  the  terms  upon  which  the  Notes  are to be
authenticated and delivered. This Note is one of a series designated on the face
hereof as limited  (except as provided in the Indenture) in aggregate  principal
amount to $250,000,000. The terms of other series of Securities issued under the
Indenture  may vary with respect to interest  rates or interest  rate  formulas,
issue dates, maturity, redemption,  repayment, currency of payment and otherwise
as provided in the Indenture.  The Indenture further provides that Securities of
a single series may be issued at various times,  with  different  maturity dates
and may bear interest at different rates.

                     This Note is not subject to any sinking fund.

     If an Event of Default (other than an Event of Default described in Section
501 (5) or 501(6) of the Indenture) with respect to the Notes shall occur and be
continuing,  then  either  the  Trustee  or the  Holders of not less than 25% in
aggregate  principal  amount of the Notes of this  series then  Outstanding  may
declare  the  aggregate  principal  amount of the Notes of this  series  due and
payable in the manner and with the effect provided in the Indenture. If an Event
of Default  specified  in Section  501(5) or 501(6)  occurs with  respect to the
Company,  all of the unpaid  principal amount and accrued interest thereon shall
ipso facto become and be immediately  due and payable in the manner and with the
effect  provided in the Indenture  without any  declaration  or other act by the
Trustee or any Holder.

     This Note may be redeemed in whole at any time at the option of the Company
(such  date of  redemption,  the  "Optional  Redemption  Date") at the  Optional
Redemption  Price (as defined below)  together with interest  accrued thereon to
the Optional  Redemption Date, on notice given not more than 60 nor less than 30
days prior to the Optional Redemption Date.

     The "Optional Redemption Price" shall equal the sum of the principal amount
of the Note and the Make Whole Amount (as defined  below).  "Make-Whole  Amount"
means,  the excess,  if any, of the  aggregate  present value as of the Optional
Redemption  Date  of  principal  being  redeemed  and  the  amount  of  interest
(exclusive of interest accrued to the Optional  Redemption Date) that would have
been payable if redemption had not been made,  determined by  discounting,  on a
semiannual basis, the remaining  principal and interest at the Reinvestment Rate
(as defined  below)  (determined  on the third  Business Day  preceding the date
notice of  redemption  is  given)  from the  dates on which  the  principal  and
interest  would have been payable if the  redemption  had not been made,  to the
Optional Redemption Date, over the aggregate principal amount of the Notes being
redeemed.

     "Reinvestment  Rate" shall mean 35 basis points plus the arithmetic mean of
the  yield  under  the  heading  "Week  Ending"  published  in the  most  recent
Statistical  Release under the caption  "Treasury  Constant  Maturities" for the
maturity  (rounded to the nearest month)  corresponding to the remaining life to
maturity,  as of the payment date of the principal being redeemed or paid. If no
maturity  exactly  corresponds  to the  maturity,  yields for the two  published
maturities most closely corresponding to the maturity shall be so calculated and
the  Reinvestment  Rate shall be interpolated or extrapolated on a straight-line
basis,  rounding  to the nearest  month.  The most  recent  Statistical  Release
published prior to the date of determination  of the Make-Whole  Amount shall be
used for purposes of calculating the Reinvestment Rate.

     The  Make-Whole  Amount shall be  calculated by an  independent  investment
banking  institution  of national  standing  appointed  by the  Company.  If the
Company fails to

make the appointment at least 45 business days prior to the Optional  Redemption
Date, or if the institution is unwilling or unable to make the calculation,  the
calculation shall be made by an independent  investment  banking  institution of
national  standing  appointed by the Trustee.  If the  Reinvestment  Rate is not
available as described  above,  the  Reinvestment  Rate shall be  calculated  by
interpolation  or  extrapolation of comparable rates selected by the independent
investment banking institution.

     The Indenture  permits,  with certain  exceptions as therein provided,  the
Company  and the  Trustee  with the  consent of the  Holders of more than 50% in
principal amount of the Securities at the time Outstanding of each series issued
under the Indenture to be affected thereby, to execute  supplemental  indentures
for the  purpose  of adding  any  provisions  to or  changing  in any  manner or
eliminating any of the provisions of the Indenture or of modifying in any manner
the rights of the Holders of the Securities of such series;  PROVIDED,  HOWEVER,
that no such supplemental  indenture shall,  among other things,  (i) change the
Stated  Maturity of the  principal  of, or any  installment  of  principal of or
interest on, any Security,  or reduce the principal  amount  thereof or interest
thereon,  if any, or any premium payable upon redemption thereof, or (ii) change
the Place of Payment on any Security or the  currency or currency  unit in which
any Security or the principal or interest  thereon is payable;  impair the right
to institute suit for the enforcement of any such payment on or after the Stated
Maturity  thereof;  or reduce or alter the method of  computation  of any amount
payable upon redemption,  repayment or purchase of any Securities by the Company
(or the time when such redemption, repayment or purchase may be made); or reduce
the percentage in principal  amount of the Securities,  the Holders of which are
required to consent to any  supplemental  indenture,  without the consent of the
Holder of each Security affected thereby. The Indenture also contains provisions
permitting the Holders of more than 50% in principal amount of the Securities of
each  series  at the time  outstanding,  on  behalf  of the  Holders  of all the
Securities  of that  series,  to waive  compliance  by the Company  with certain
provisions of the  Indenture  and certain past defaults  under the Indenture and
their consequences with respect to such series,  except a default in the payment
of principal of or interest, if any, on any Security of that series or a default
with respect to a covenant or provision of the Indenture which cannot be amended
without the consent of such Holder.

     The  Notes  are  issuable  only  in  registered  form  without  coupons  in
denominations  of $1,000 and  integral  multiples  thereof.  As  provided in the
Indenture and subject to certain  limitations  therein set forth,  the Notes are
exchangeable for a like aggregate  principal amount of Notes as requested by the
Holder  surrendering the same. If (x) the Depositary is at any time unwilling or
unable to continue as depository and a successor  depository is not appointed by
the  Company  within 90 days after the Company  receives  such notice or becomes
aware of such  ineligibility,  (y) the Company delivers to the Trustee a Company
Order to the  effect  that this Note  shall be  exchangeable  or (z) an Event of
Default has occurred  and is  continuing  with  respect to the Notes,  this Note
shall be  exchangeable  for Notes in definitive  form and in an equal  aggregate
principal  amount.  Such  definitive  Notes shall be  registered in such name or
names as the Depositary shall instruct the Trustee.

     As provided in the Indenture and subject to certain  limitations  set forth
therein and above,  the transfer of this Note may be  registered on the Security
Register  of the  Company,  upon  surrender  of this  Note for  registration  of
transfer at the office or agency of the Company in the Borough of Manhattan, The
City of New York,  duly endorsed by, or accompanied  by a written  instrument of
transfer in form satisfactory to the Company duly executed by, the Holder hereof
or by his attorney  duly  authorized  in writing,  and thereupon one or more new
Notes of authorized  denominations  and for the same aggregate  principal amount
will be issued to the designated transferee or transferees.

     No reference  herein to the  Indenture  and no provision of this Note or of
the  Indenture  shall alter or impair the  obligation  of the Company,  which is

purposes,  whether or not this Note be overdue,  and neither  the  Company,  the
Trustee nor any such agent shall be affected by notice to the contrary.

     Certain of the Company's  obligations  under the Indenture  with respect to
Notes,  may be terminated if the Company  irrevocably  deposits with the Trustee
money or  Government  Obligations  sufficient  to pay and  discharge  the entire
indebtedness on all Notes, as provided in the Indenture.

     No recourse  shall be had for the payment of the principal of (and premium,
if any), or the interest,  if any, on this Note, or for any claim based thereon,

against the any incorporator,  stockholder,  officer or director, as such, past,

assessment of penalty or otherwise; and all such personal liability is expressly
released and waived as a condition of, and as part of the consideration for, the
issuance of this Note.
