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 1.4  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 an agent duly appointed in writing;
and, except as herein  otherwise  expressly  provided,  such action shall become
effective when such  instrument or instruments are delivered to the Trustee and,
where it is hereby  expressly  required,  to the  Company.  Such  instrument  or
instruments (and the action embodied  therein and evidenced  thereby) are herein
sometimes  referred to as the "Act" of the Holders  signing such  instrument  or
instruments.  Proof  of  execution  of  any  such  instrument  or  of a  writing
appointing  any such agent shall be sufficient for any purpose of this Indenture
and (subject to Section 6.1) conclusive in favor of the Trustee and the Company,
if made in the manner provided in this Section.

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

     (c) The Company may, in the circumstances  permitted by the Trust Indenture
Act, fix any day as the record date for the purpose of  determining  the Holders
entitled to give or take any request, demand, authorization,  direction, notice,
consent,  waiver  or  other  action,  or to vote on any  action,  authorized  or
permitted  to be given or taken by Holders.  If not set by the Company  prior to
the first  solicitation  of a Holder  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 the 30th day (or, if later, the date of the
most recent list of Holders  required  to be provided  pursuant to Section  7.1)
prior to such first solicitation or vote, as the case may be. With regard to any
record date,  only the Holders on such date (or their duly  designated  proxies)
shall be entitled to give or take, or vote on, the relevant action.

      (d)     The ownership of Securities shall be proved by the Security 
Register.

      (e) Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Holder of any Security shall bind every future Holder of the
same Security and the Holder of every Security  issued upon the  registration of
transfer  thereof  or in  exchange  therefor  or in lieu  thereof  in respect of
anything  done,  omitted or suffered to be done by the Trustee or the Company in
reliance  thereon,  whether  or not  notation  of such  action is made upon such
Security.

Section 1.5   Notices, Etc., to Trustee or Company.
              ------------------------------------

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

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

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

Section 1.6  Notice to Holders; Waiver.
             -------------------------

     Where this  Indenture  provides  for  notice to Holders of any event,  such
notice shall be sufficiently given (unless otherwise herein expressly  provided)
if in writing and mailed,  first-class  postage prepaid, to each Holder affected
by such event, at 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.  In any case  where  notice to Holders is given by mail,
neither the failure to mail such notice, nor any defect in any notice so mailed,
to any  particular  Holder  shall  affect the  sufficiency  of such  notice with
respect  to other  Holders.  Where  this  Indenture  provides  for notice in any
manner,  such notice may be waived in writing by the Person  entitled to receive
such  notice,  either  before or after the event,  and such waiver  shall be the
equivalent of such notice.  Waivers of notice by Holders shall be filed with the
Trustee,  but such filing shall not be a condition  precedent to the validity of
any action taken in reliance upon such waiver.

     In case by reason of the suspension of regular mail service or by reason of
any other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall  constitute
a sufficient notification for every purpose hereunder.

Section 1.7  Conflict with Trust Indenture Act.
             ---------------------------------

     If any provision hereof limits,  qualifies or conflicts with a provision of
the Trust  Indenture  Act that is  required  under  such Act to be a part of and
govern this Indenture,  the latter provision shall control.  If any provision of
this  Indenture  modifies or excludes any  provision of the Trust  Indenture Act
that may be so modified or  excluded,  the latter  provision  shall be deemed to
apply to this Indenture as so modified or to be excluded, as the case may be.

Section 1.8   Effect of Headings and Table of Contents.
              ----------------------------------------

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

Section 1.9   Successors and Assigns.
              ----------------------

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

Section 1.10   Separability Clause.
               -------------------

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

Section 2.1  Benefits of Indenture.
             ---------------------

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

Section 1.12  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 1.13  Legal Holidays.
              --------------

In any case where any Interest Payment Date,  Redemption Date or Stated Maturity
of any  Security  or the last date on which a Holder has the right to convert or
exchange  his  Securities  shall not be a Business  Day at any Place of Payment,
then   (notwithstanding  any  other  provision  of  this  Indenture  or  of  the
Securities) payment of interest or principal (and premium, if any) or conversion
or exchange of the Securities  need not be made at such Place of Payment on such
date,  but may be made on the  next  succeeding  Business  Day at such  Place of
Payment with the same force and effect as if made on the  Interest  Payment Date
or  Redemption  Date,  or at the  Stated  Maturity,  or on  such  last  day  for
conversion or exchange,  provided  that no interest  shall accrue for the period
from and after such Interest  Payment Date,  Redemption Date or Stated Maturity,
as the case may be,  except that if such  succeeding  Business  Day falls in the
next calendar year, payment shall be made on the immediately  preceding Business
Day.

if any) and/or interest on the Securities of such series shall be payable;

          (16) if the principal of (and premium,  if any) and/or interest on the

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

Section 3.2  Denominations.
             -------------

     The Securities of each series shall be issuable in registered  form without
coupons in such  denominations  as shall be specified as contemplated by Section
3.1. In the absence of any such provisions with respect to the Securities of any
series,  the  Securities  of such series shall be issuable in  denominations  of
$1,000 and any integral multiple thereof.

Section 3.3  Execution, Authentication, Delivery and Dating.
             ----------------------------------------------

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

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

     At any time and from time to time after the  execution and delivery of this
Indenture,  the  Company may deliver  Securities  of any series  executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication  and delivery of such  Securities;  and the Trustee in accordance
with such Company Order shall  authenticate and deliver such Securities.  If the
form or terms of the  Securities  of the  series  have  been  established  in or
pursuant to one or more Board Resolutions or Officers' Certificates as permitted
by Sections 2.1 and 3.1, in  authenticating  such Securities,  and accepting the
additional responsibilities under this Indenture in relation to such Securities,
the Trustee shall be entitled to receive,  and (subject to Section 6.1) shall be
fully protected in relying upon, an Opinion of Counsel stating,

          (a) if the form of any of such  Securities has been  established by or
pursuant to Board  Resolution or Officers'  Certificate  as permitted by Section
2.1, that such form has been  established  in conformity  with the provisions of
this Indenture;

          (b) if the terms of any of such Securities have been established by or
pursuant to Board  Resolution or Officers'  Certificate  as permitted by Section
3.1, that such terms have been  established in conformity with the provisions of
this Indenture; and

          (c) that such  Securities,  when  authenticated  and  delivered by the
Trustee and issued by the  Company in the manner and  subject to any  conditions
specified in such Opinion of Counsel,  will constitute valid and legally binding
obligations of the Company enforceable in accordance with its terms,  subject to
bankruptcy,  insolvency, reorga nization and other laws of general applicability
relating to or affecting the  enforcement  of  creditors'  rights and to general
equity principles.

     If the Company shall establish  pursuant to Section 3.1 that the Securities
of a  series  are to be  issued  in the  form of one or more  registered  global
securities,  then the Company shall execute and the Trustee shall, in accordance
with  this  Section  and  the  Company   Order  with  respect  to  such  series,
authenticate  and deliver one or more registered  global  securities that (a)(i)
shall  represent  and shall be  denominated  in an amount equal to the aggregate
principal  amount of all of the  Securities  of such  series  issued and not yet
canceled, (ii) shall be registered in the name of DTC or a nominee of DTC, (iii)
shall be delivered by the Trustee to DTC or pursuant to DTC's instructions,  and
(iv) shall bear a legend  substantially  to the  following  effect:  "Unless and
until  it is  exchanged  in  whole  or in  part  for  Securities  in  definitive
registered  form, this Security may not be transferred  except as a whole by DTC
to a nominee of DTC or by a nominee  of DTC to DTC or another  nominee of DTC or
by DTC or any such nominee to a successor to DTC or a nominee of such successor"
or such other  legend as shall be  acceptable  to DTC; or (b) shall  comply with
such  other  terms or  procedures  as may be set forth in a Company  Order  with
respect  to such  series.  Notwithstanding  that such form or terms have been so
established,  the Trustee shall not be required to authenticate  such Securities
if the issue of such  Securities  pursuant  to this  Indenture  would  adversely
affect the Trustee's own rights,  duties or immunities  under the Securities and
this  Indenture or otherwise in a manner which is not  reasonably  acceptable to
the Trustee.

     Notwithstanding  the  provisions  of  Section  3.1  and  of  the  preceding
paragraph,  if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers'  Certificate  otherwise
required  pursuant to Section  3.1 or the  Company  Order and Opinion of Counsel
otherwise required pursuant to such preceding  paragraph at or prior to the time
of  authentication  of each  Security  of such  series  if  such  documents  are
delivered at or prior to the time of  authentication  upon original  issuance of
the first Security of such series to be issued.

     Each Security shall be dated the date of its authentication.

     No Security  shall be entitled to any benefit  under this  Indenture  or be
valid or  obligatory  for any purpose  unless there  appears on such  Security a
certificate  of  authentication  substantially  in the form  provided for herein
executed  by the  Trustee by manual  signature,  and such  certificate  upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly  authenticated  and  delivered  hereunder  and is  entitled to the
benefits of this Indenture. Notwithstanding the foregoing, if any Security shall
have been authenticated and delivered hereunder but never issued and sold by the
Company,  and the  Company  shall  deliver  such  Security  to the  Trustee  for
cancellation as provided in Section 3.9, together with an Officers'  Certificate
(which  need not  comply  with  Section  1.2 and need not be  accompanied  by an
Opinion of Counsel) stating that such Security has never been issued and sold by
the Company,  for all purposes of this  Indenture  such Security shall be deemed
never to have been  authenticated  and  delivered  hereunder  and shall never be
entitled to the benefits of this Indenture.

Section 3.4 Temporary Securities.
            --------------------

     Pending the preparation of definitive Securities of any series, the Company
may execute, and upon Company Order, the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed,  typewritten, mimeographed
or otherwise  produced,  in any authorized  denomination,  substantially  of the
tenor of the definitive  securities in lieu of which they are issued,  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.

     If temporary  Securities  of any series are issued,  the Company will cause
definitive  Securities of that series to be prepared without unreasonable delay.
After the  preparation  of definitive  Securities of such series,  the temporary
Securities of such series shall be  exchangeable  for  definitive  securities of
such series upon  surrender of the  temporary  Securities  of such series at the
office or agency of the Company in a Place of Payment for that  series,  without
charge  to the  Holder.  Upon  surrender  for  cancellation  of any  one or more
temporary  Securities  of any series,  the Company shall execute and the Trustee
shall  authenticate and deliver in exchange  therefor a like principal amount of
definitive  Securities  of the same  series  and of like  tenor,  of  authorized
denominations.  Until so exchanged, the temporary Securities of any series shall
in all  respects  be  entitled  to the same  benefits  under this  Indenture  as
definitive Securities of such series.

Section 3.5 Registration, Registration of Transfer and Exchange.
            ---------------------------------------------------

     The Company  shall cause to be kept at the  Corporate  Trust  Office of the
Trustee  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 Securities and of transfers of Securities. The Trustee is hereby
appointed  "Security  Registrar" for the purpose of  registering  Securities and
transfers of Securities as herein provided.

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

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

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

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

     No  service  charge  shall  be made for any  registration  of  transfer  or
exchange of Securities,  but the Company may require payment of a sum sufficient
to cover any tax or other governmental  charge that may be imposed in connection
with any  registration  of  transfer  or  exchange  of  Securities,  other  than
exchanges pursuant to Section 3.4, 9.6 or 11.7 not involving any transfer.

     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 11.3 and ending
at the close of business  on the day of such  mailing,  or (ii) to register  the
transfer of or exchange any Security so selected for  redemption  in whole or in
part, except the unredeemed portion of any Security being redeemed in part.

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

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

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

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

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

     Every new Security of any series,  issued  pursuant to this Section in lieu
of  any  destroyed,  lost  or  stolen  Security  shall  constitute  an  original
additional contractual obligation of the Company,  whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately  with
any and all other Securities of that series duly issued hereunder.

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

Section 3.7 Payment of Interest; Interest Rights Preserved.
            ----------------------------------------------

     Unless  otherwise  provided as  contemplated by Section 3.1 with respect to
any series of  Securities,  interest on any  Security  which is payable  (unless
payment has been deferred  pursuant to the exercise of a right of the Company so
to defer),  and is punctually paid or duly provided for, on any Interest Payment
Date  shall be paid to the Person in whose  name that  Security  (or one or more
Predecessor  Securities)  is  registered at the close of business on the Regular
Record Date for such interest.

     Any  interest on any  Security of any series  which is payable,  but is not
punctually paid or duly provided for for any reason, including the exercise of a
right of the Company to defer such  interest  payment,  on any Interest  Payment
Date (herein called "Delayed  Interest")  shall forthwith cease to be payable to
the Person  entitled to such interest by virtue of having been such Holder,  and
such Delayed Interest may be paid by the Company,  at its election in each case,
as provided in Clauses (1), (2) or (3) below:

          (1)   With respect to any Delayed Interest resulting from the exercise
of a right of the Company to defer such Delayed Interest, the Company may elect
to make payment, in whole or in part,as hereinafter provided in this 
subparagraph (1).  The Company may elect -
     
    to make payment to the Persons in whose names the Securities of such series
are registered at the close of business on a Special Record Date for the payment
of such Delayed  Interest,  which shall be fixed by the Company in the following
manner: The Company shall notify the Trustee in writing of the amount of Delayed
Interest  proposed to be paid on each  Security of such series,  the date of the
proposed  payment if payment  is to be in shares of Common  Stock (the  "Special
Stock  Transfer and Valuation  Date"),  and the date of the proposed  payment if
payment is to be in cash (the "Special Cash Interest Payment Date"), which shall
also be the "Special  Distribution Payment Date" for purposes of the Partnership
Preferred  Securities and the Convertible  Preferred  Securities and the related
distribution.  Thereupon  the  Company  shall  fix a  special  record  date (the
"Special  Record Date") for the payment of such Delayed  Interest which shall be
not  more  than 35 days  and not  less  than 15 days  prior  to the  date of the
proposed  payment.  The Company  shall  promptly  cause  notice of the  proposed
payment of such Delayed  Interest and the Special  Record  Date,  Special  Stock
Transfer and  Valuation  Date,  Special Cash  Interest  Payment Date and Special
Distribution Payment Date therefor to be mailed, first-class postage prepaid, or
delivered by courier  service or by hand  delivery or by any other manner deemed
practicable  by the Trustee,  to each Holder of Securities of such series at his
address as it appears in the Security  Register,  not less than 10 days prior to
such  Special  Record  Date.  Notice of the  proposed  payment  of such  Delayed
Interest  and such  dates  therefor  having  been so mailed or  delivered,  such
Delayed  Interest  shall be paid to the Persons in whose names the Securities of
such series are  registered at the close of business on such Special Record Date
and shall no longer be payable pursuant to the following Clauses (2) or (3).

          (2)  With  respect  to any  Delayed  Interest  which  has not been the
subject of the exercise of the Company's  right to defer,  the Company may elect
to make  payment of any  Delayed  Interest  to the  Persons  in whose  names the
Securities  of such  series (or their  respective  Predecessor  Securities)  are
registered at the close of business on a Special  Record Date for the payment of
such Delayed Interest, which shall be fixed in the following manner. The Company
shall notify the Trustee in writing of the amount of Delayed  Interest  proposed
to be paid on each Security of such series and the date of the proposed payment,
which shall be  established  so as to permit  adequate time for the time periods
noted below,  and at the same time the Company shall deposit with the Trustee an
amount of money equal to the aggregate  amount proposed to be paid in respect of
such Delayed Interest or shall make arrangements satisfactory to the Trustee for
such  deposit  prior  to the  date of the  proposed  payment,  such  money  when
deposited  to be held in trust for the benefit of the  Persons  entitled to such
Delayed Interest as in this Clause  provided.  Thereupon the Trustee shall fix a
special record date (the "Special  Record Date") for the payment of such Delayed
Interest which shall be not more than 30 days and not less than 15 days prior to
the date of the proposed  payment and not less than 10 days after the receipt by
the Trustee of the notice of the proposed  payment.  The Trustee shall  promptly
notify  the  Company of such  Special  Record  Date and,  in the name and at the
expense of the  Company,  shall  cause  notice of the  proposed  payment of such
Delayed Interest and the Special Record Date therefor to be mailed,  first-class
postage prepaid, or delivered by courier service or by hand delivery,  or by any
other manner deemed practicable by the Trustee,  to each Holder of Securities of
such series at his address as it appears in the Security Register, not less than
10 days prior to such  Special  Record Date.  Notice of the proposed  payment of
such Delayed Interest and the Special Record Date therefor having been so mailed
or delivered,  such Delayed Interest shall be paid to the Persons in whose names
the Securities of such series (or their respective  Predecessor  Securities) are
registered  at the close of  business on such  Special  Record Date and shall no
longer be payable pursuant to the following Clause (3).
          (3) The  Company  may make  payment  of any  Delayed  Interest  on the
Securities  of any series in any other lawful manner not  inconsistent  with the
requirements  of any securities  exchange on which such Securities may be listed
or any book-entry security system which may be applicable to the Debentures, and
upon such notice as may be required by such exchange or system, if, after notice
given by the Company to the  Trustee of the  proposed  payment  pursuant to this
Clause, such manner of payment shall be deemed practicable by the Trustee.

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

     In the case of any Security  which is  converted  or exchanged  (other than
exchanges  pursuant  to Section  3.5) after any  Regular  Record Date or Special
Record Date and on or prior to the next succeeding  Interest Payment Date (other
than any  Security  whose  Maturity  is prior to such  Interest  Payment  Date),
interest whose Stated Maturity is on such Interest Payment Date shall be payable
on such Interest Payment Date notwithstanding  such conversion or exchange,  and
such  interest  (whether or not  punctually  paid or duly provided for) shall be
paid to the  Person in whose  name  that  Security  (or one or more  Predecessor
Securities)  is registered at the close of business on such Regular  Record Date
or  Special  Record  Date.  Except  as  otherwise   expressly  provided  in  the
immediately  preceding sentence,  in the case of any Security which is converted
or exchanged,  interest whose Stated Maturity is after the date of conversion or
exchange of such Security  shall not be payable,  and the Company shall not make
nor be required to make any other payment,  adjustment or allowance with respect
to accrued but unpaid interest on the Securities being converted or exchanged.

Section 3.8  Persons Deemed Owners.
             ---------------------

     Prior to due presentment of a Security for  registration  of transfer,  the
Company,  the  Trustee and any agent of the Company or the Trustee may treat the
Person in whose name such  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 3.7)  interest on such  Security and for all other  purposes
whatsoever,  whether or not such  Security be overdue,  and neither the Company,
the Trustee  nor any agent of the  Company or the  Trustee  shall be affected by
notice to the contrary.

Section 3.9 Cancellation.
            ------------

     All  Securities  surrendered  for  payment,  redemption,   registration  of
transfer or exchange or conversion or exchange or for credit against any sinking
fund payment  shall,  if  surrendered  to any Person other than the Trustee,  be
delivered  to the Trustee and shall be promptly  canceled by it. The Company may
at any time deliver to the Trustee for  cancellation  any Securities  previously
authenticated and delivered hereunder which the Company may have acquired in any
manner  whatsoever,  and  may  deliver  to  the  Trustee  for  cancellation  any
Securities previously  authenticated  hereunder which the Company has not issued
and sold and all  Securities  so  delivered  shall be  promptly  canceled by the
Trustee.  No Securities shall be authenticated in lieu of or in exchange for any
Securities  canceled as provided in this Section,  except as expressly permitted
by this Indenture. All canceled Securities held by the Trustee shall be disposed
of as  directed  by a Company  Order from the  Company or in the absence of such
Company Order, in accordance with the Trustee's standard procedures.

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

     Except as otherwise specified as contemplated by Section 3.1 for Securities
of any 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 3.11 Book-Entry Securities.
     (a)  Except  as  provided  in  subsection  (c) of this  Section  3.11,  the
registered  owner  of all  Securities  of any  series  of  Securities  which  is
designated as a Book Entry Security  series in the Board  Resolution,  Officers'
Certificate,  indenture  supplemental  hereto establishing such series, or other
instrument  supplemental hereto, shall be CEDE & Co., as nominee of DTC. Payment
of interest for any Securities  registered as of each Record Date in the name of
CEDE & Co.  shall be made by wire  transfer  to the account of CEDE & Co. on the
Interest Payment Date for such Securities at the address indicated on the Record
Date for CEDE & Co. in the registration books of the Company kept by Trustee, as
Security Registrar.

     (b) With respect to any  Book-Entry  Securities,  the  Securities  shall be
issued in the form of one or more  fully  registered  global  securities  in the
principal amount of each separate series of the Securities.  Upon issuance,  the
ownership of such Securities  shall be registered in the  registration  books of
the  Company  kept by the  Trustee in the name of CEDE & Co., as nominee of DTC.
The  Trustee  and the  Company  may treat DTC (or its  nominee)  as the sole and
exclusive  owner of the  Securities  registered  in its name for the purposes of
payment of the principal of,  premium,  if any, or interest on such  Securities,
giving any  notice  permitted  or  required  to be given to  Holders  under this
Indenture, registering the transfer of such Securities, obtaining any consent or
other action to be taken by Holders and for all other purposes  whatsoever;  and
neither  the  Trustee  nor the  Company  shall be  affected by any notice to the
contrary.  Neither the Trustee nor the Company shall have any  responsibility or
obligation to any DTC  participant,  any Person claiming a beneficial  ownership
interest in Securities registered in the name of CEDE & Co. under or through DTC
or  any  DTC  participant,  or any  other  Person  which  is  not  shown  on the
registration  books of the  Company  kept by the  Trustee as being a Holder with
respect to the accuracy of any records  maintained by DTC, CEDE & Co. or any DTC
participant;  the payment by DTC or any DTC participant to any beneficial  owner
of any amount in respect of the  principal of,  premium,  if any, or interest on
the  Securities  registered  in the name of CEDE & Co.;  the delivery to any DTC
participant or any beneficial owner of any notice which is permitted or required
to be given to Holders  under this  Indenture;  the  selection by DTC or any DTC
participant of any Person to receive  payment in the event of a partial  payment
of any Securities  registered in the name of CEDE & Co.; or any consent given or
other  action taken by DTC as Holder.  The Paying Agent shall pay all  principal
of,  premium,  if any, and interest on any Securities  registered in the name of
CEDE & Co.,  only to or upon the order of CEDE & Co., as nominee of DTC, and all
such  payments  shall be valid and  effective to fully satisfy and discharge the
Company's  obligations  with respect to the principal of,  premium,  if any, and
interest  on such  Securities  to the  extent  of the sum or sums so paid.  Upon
delivery  by DTC to the  Trustee  of written  notice to the effect  that DTC had
determined  to  substitute  a new nominee in place of CEDE & Co., and subject to
the  provisions  herein with respect to record dates,  the words "CEDE & Co." in
this Indenture shall refer to such new nominee of DTC.

     (c) With respect to any series of  Securities  registered or proposed to be
registered  in the name of CEDE & Co.,  in the  event  that (i) DTC gives or has
given notice that it will discontinue its services as securities  depository for
such  series of  Securities;  or (ii) DTC  ceases or has ceased to be a clearing
house registered under the Securities Exchange Act of 1934; or (iii) the Company
in its sole discretion  determines or has determined that the beneficial  owners
of such Securities will be entitled to obtain definitive  certificates;  or (iv)
an Event of Default with respect to such series has occurred and is  continuing,
the  Company  shall,  if the event is  triggered  by either  (i) or (ii)  above,
attempt to locate another qualified securities depository.  If the Company fails
to locate such a  replacement  or if the event is  triggered  by either (iii) or
(iv) above,  then it shall notify DTC and the Trustee,  requesting DTC to notify
its participants, of the availability through DTC of definitive certificates. In
any such event,  the Trustee shall issue,  register the transfer of and exchange
definitive certificates as requested by DTC and any other Holders in appropriate
amounts.  The Company and the Trustee  shall be obligated to deliver  definitive
certificates   as  described  in  this  Indenture.   In  the  event   definitive
certificates  are  issued to  Holders  other than DTC,  the  provisions  of this
Indenture shall apply to, among other things, the registration,  transfer of and
exchange  of such  certificates  and the  method of  payment  of  principal  of,
premium,  if any, and interest on such  certificates.  Whenever DTC requests the
Company and the Trustee to do so, the  Trustee  and the Company  will  cooperate
with DTC in  taking  appropriate  action  after  reasonable  notice  (i) to make
available one or more separate certificates evidencing the Securities registered
in the name of CEDE & Co., to any DTC participant having Securities  credited to
its DTC account or (ii) to arrange for another securities depository to maintain
custody of  certificates  evidencing  such  Securities.  If the  Company  uses a
securities depository other than DTC, the provisions of this Section shall apply
with the appropriate modifications.

     (d)  Notwithstanding any other provision of this Indenture to the contrary,
so long as any  Securities  are registered in the name of CEDE & Co., as nominee
of DTC, all payments  with respect to the  principal  of,  premium,  if any, and
interest on such  Securities  and all notices,  with respect to such  Securities
shall  be  made  and  given  to DTC as  provided  in the  applicable  Letter  of
Representation.

     (e) In connection with any notice or other  communication to be provided to
Holders pursuant to this Indenture by the Company or the Trustee with respect to
any consent or other action to be taken by Holders so long as any  Securities of
a series  are  registered  in the name of CEDE & Co.,  as  nominee  of DTC,  the
Company or the Trustee,  as the case may be,  shall  establish a record date for
such  consent or other  action and give DTC notice of such  record date not less
than 15 calendar days in advance of such record date to the extent possible.

     (f) The  notice  requirements  set forth in the  Letter  of  Representation
relating  to  the  Securities  of  any  series  with  respect  to   redemptions,
conversions  and mandatory  tenders shall be effective  whenever such Securities
are  Book  Entry  Securities,  notwithstanding  any  other  provisions  of  this
Indenture,  to the extent such other provisions are incompatible with the notice
requirements set forth in the Letter of Representation.

caused to be deposited  with the Trustee as trust funds in trust for the purpose

Company has made any  payment of  principal  of or  interest  on any  Securities

Section 5.2 Acceleration of Maturity; Rescission and Annulment.

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

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

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

          (A)   all overdue interest on all Securities of that series, other 
than interest deferred in accordance with the provisions of any supplemental 
indenture,

          (B) the principal of (and premium,  if any, on) any Securities of that
series which have become due otherwise than by such  declaration of acceleration
and  interest  thereon  at  the  rate  or  rates  prescribed  therefor  in  such
Securities,

          (C) to the extent that  payment of such  interest is lawful,  interest
upon  overdue  interest  at the  rate  or  rates  prescribed  therefor  in  such
Securities, and

          (D)   all sums paid or advanced by the Trustee hereunder and the 
reasonable compensation, expenses, disbursements and advances of the Trustee, 
its agents and counsel;

     and

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

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

Section 5.3  Collection of Indebtedness and Suits for Enforcement by Trustee.
- --------------------------------------------------------
- -------


          The Company covenants that if

          (1)   default occurs in the payment of any interest on any Security 
when such interest becomes due and payable and such default continues for a 
period of 60 days;

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

          (3)   default occurs in the deposit of any sinking fund payment, when
and as due by the terms of a Security of that series;

     the Company will, upon demand of the Trustee, pay to it, for the benefit of
the Holders of such  Securities,  the whole  amount then due and payable on such
Securities for principal  (and premium,  if any) and interest and, to the extent
that  payment of such  interest  shall be legally  enforceable,  interest on any
overdue principal (and premium, if any) and on any overdue interest, at the rate
or rates prescribed  therefor in such Securities,  and, addition  thereto,  such
further  amount  as shall be  sufficient  to cover the  costs  and  expenses  of
collection,  including the reasonable compensation,  expenses, disbursements and
advances of the Trustee, its agents and counsel.

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

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

Section 5.4 Trustee May File Proofs of Claim.

judicial  proceeding  relative  to the  Company  or any other  obligor  upon the
Securities  or the  property  of the  Company or of such other  obligor or their
creditors,  the Trustee (irrespective of whether the principal of the Securities
shall  then be due  and  payable  as  therein  expressed  or by  declaration  or
otherwise and  irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue  principal or interest) shall be entitled
and empowered,  by intervention in such proceeding or otherwise, to take any and
all actions authorized by the Trust Indenture Act in order to have claims of the
Holders  of  Securities  of any  series  and the  Trustee  allowed  in any  such
proceeding. In particular the Trustee shall be authorized,

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

          (ii) to collect and receive  any moneys or other  property  payable or
deliverable  on any such claims and to distribute  the same;  and any custodian,
receiver, assignee, trustee, liquidator,  sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee  shall consent to the
making of such  payments  directly  to the  Holders,  to pay to the  Trustee any
amount  due it for the  reasonable  compensation,  expenses,  disbursements  and
advances of the Trustee,  its agents and counsel,  and any other amounts due the
Trustee under Section 6.7.

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

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 the Trustee,  its agents and counsel,  be for the ratable benefit of
the  Holders  of the  Securities  in respect  of which  such  judgment  has been
recovered.

have any right in any  manner  whatever  by virtue  of,  or by  availing  of any
provision of this  Indenture to affect,  disturb or prejudice  the rights of any
other of such Holders,  or to obtain or to seek to obtain priority or preference
over any other of such  Holders or to enforce  any right  under this  Indenture,

            Interest and to Convert or Exchange.

enforcement  of any such  payment  and right to  convert or  exchange,  and such
rights shall not be impaired without the consent of such Holder.

Section 5.9 Restoration of Rights and Remedies
            ----------------------------------
     If the Trustee or any Holder has  instituted  any proceeding to enforce any
right or remedy under this Indenture and such  proceeding has been  discontinued

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.

             ----------------------------
     No delay or omission of the Trustee or of any Holder of any  Securities  to

which is not inconsistent with such direction.

series and its consequences, except a default

          (2) in respect of 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 such series affected.

     Upon any such waiver,  such default shall cease to exist,  and any Event of

suffered 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

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

respect  to the  Securities  of one or  more  series,  the  Company,  by a Board
Resolution,  shall promptly appoint a successor Trustee or Trustees with respect
to the  Securities  of that or those series (it being  understood  that any such
successor Trustee may be appointed with respect to the Securities of one or more
or all of such series and that at any time there shall be only one Trustee  with
respect to the  Securities of any  particular  series) and shall comply with the
applicable  requirements  of  Section  6.11.  If,  within  one year  after  such
resignation,  removal or  incapability,  or the  occurrence of such  vacancy,  a
successor  Trustee  with  respect  to the  Securities  of any  series  shall  be
appointed  by Act of the  Holders  of a  majority  in  principal  amount  of the
Outstanding  Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such  appointment in accordance  with the applicable  requirements of Section
6.11, become the successor Trustee with respect to the Securities of such series
and to that extent supersede the successor Trustee appointed by the Company.  If
no successor  Trustee with  respect to the  Securities  of any series shall have
been so appointed by the Company or the Holders and accepted  appointment in the
manner required by Section 6.11, any Holder who has been a bona fide Holder of a
Security  of such  series for at least six months  may, on behalf of himself and
all others similarly situated,  petition any court of competent jurisdiction for
the  appointment  of a successor  Trustee with respect to the Securities of such
series.

          (f) The Company shall give notice of each resignation and each removal
of the Trustee with respect to the securities of any series and each appointment
of a successor  Trustee with respect to the  Securities of any series by mailing
written  notice of such  event by  first-class  mail,  postage  prepaid,  to all
Holders of Securities of such series as their names and addresses  appear in the
Security  Register.  Each notice shall include the name of the successor Trustee
with respect to the  Securities  of such series and the address of its Corporate
Trust Office.

Section 6.11  Acceptance of Appointment by Successor.
              --------------------------------------
          (a) In case of the appointment  hereunder of a successor  Trustee with
respect to all  Securities,  every such  successor  Trustee so  appointed  shall
execute,  acknowledge  and deliver to the Company  and the  retiring  Trustee an
instrument accepting such appointment,  and thereupon the resignation or removal
of the retiring  Trustee  shall become  effective  and such  successor  Trustee,
without any further act,  deed or  conveyance,  shall become vested with all the
rights,  powers,  trusts and duties 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
that all the rights,  powers,  trusts and duties of the  retiring  Trustee  with
respect  to the  Securities  of that or those  series as to which  the  retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the  provisions of this  Indenture as shall be
necessary  to  provide  for or  facilitate  the  administration  of  the  trusts
hereunder by more than one Trustee,  it being  understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same  trust and that each such  Trustee  shall be  trustee  of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder  administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture  the  resignation  or removal of the  retiring  Trustee  shall  become
effective  to the  extent  provided  therein  and each such  successor  Trustee,
without any further act,  deed or  conveyance,  shall become vested with all the
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 paragraph (a) and (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 shall be qualified and eligible
under this Article.

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

     Any  corporation  into which the Trustee may be merged or converted or with
which it may be  consolidated,  or any  corporation  resulting  from any merger,
conversion  or  consolidation  to which  the  Trustee  shall be a party,  or any
corporation  succeeding to all or substantially all the corporate trust business
of the Trustee,  shall be the successor of the Trustee hereunder,  provided such
corporation  shall be  otherwise  qualified  and  eligible  under this  Article,
without the  execution  or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not  delivered,  by the Trustee  then in office,  any  successor  by merger,
conversion  or  consolidation  to such  authenticating  Trustee  may adopt  such
authentication  and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

Section 6.13 Preferential Collection of Claim Against Company.
             ------------------------------------------------
          If and  when the  Trustee  shall  be,  or shall  become,  a  creditor,
directly  or  indirectly,  secured or  unsecured,  of the  Company (or any other
obligor upon the Securities),  the Trustee shall be subject to the provisions of
Section 3.11 of the Trust Indenture Act.

Section 6.14 Appointment of Authenticating Agent.
             -----------------------------------

     At any time when any of the Securities remain Outstanding,  the Trustee may
appoint an Authenticating  Agent or Agents with respect to one or more series of
Securities  which  shall  be  authorized  to act on  behalf  of the  Trustee  to
authenticate  Securities of such series issued upon  exchange,  registration  of
transfer  or  partial  redemption  thereof  or  pursuant  to  Section  3.6,  and
Securities so authenticated  shall be entitled to the benefits of this Indenture
and shall be valid and  obligatory for all purposes as if  authenticated  by the
Trustee  hereunder.  Wherever  reference  is  made  in  this  Indenture  to  the
authentication  and  delivery  of  Securities  by the  Trustee or the  Trustee's
certificate  of  authentication,  such  reference  shall be  deemed  to  include
authentication and delivery on behalf of the Trustee by an Authenticating  Agent
and a  certificate  of  authentication  executed  on behalf of the Trustee by an
Authenticating  Agent.  Each  Authenticating  Agent shall be  acceptable  to the
Company and shall at all times be a  corporation  organized  and doing  business
under  the laws of the  United  States of  America,  any  State  thereof  or the
District of Columbia, authorized under such laws to act as Authenticating Agent,
having a combined  capital and surplus of not less than  $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 to the requirements of said supervising or examining  authority,  then
for the  purposes  of this  Section,  the  combined  capital and surplus of such
Authenticating  Agent shall be deemed to be its combined  capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating  Agent  shall  cease  to  be  eligible  in  accordance  with  the
provisions of this Section,  such Authenticating  Agent shall resign immediately
in the manner and with the effect specified in this Section.

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

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

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

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

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

or served at the Corporate  Trust Office of the Trustee,  and the Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands.

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

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

     If the Company  shall at any time act as its own Paying  Agent with respect
to any  series  of  Securities,  it  will,  on or  before  each  due date of the
principal of (and premium,  if any) or interest on any of the Securities of that
series,  segregate  and hold in trust for the  benefit of the  Persons  entitled
thereto a sum sufficient to pay the principal (and premium,  if any) or interest
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 of its
failure so to act.

     Whenever the Company shall have one or more Paying Agents for any series of
Securities,  it  will,  on or  before  each due  date of the  principal  of (and
premium,  if any) or interest on any  Securities of that series,  deposit with a
Paying Agent a sum  sufficient  to pay the principal  (and  premium,  if any) or
interest  so becoming  due,  such sum to be held in trust for the benefit of the
Persons entitled to such principal, premium or interest, and (unless such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of its action
or failure so to act.

     The Company will cause each Paying Agent for any series of Securities other
than the Trustee to execute and  deliver to the Trustee an  instrument  in which
such Paying Agent shall agree with the  Trustee,  subject to the  provisions  of
this Section, 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  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 the Trustee notice of any default by the Company in the 
making of any payment of principal (and premium, if any) or interest on the 
Securities of that series; and

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

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

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company in trust for the payment of the principal of (and  premium,  if any)
or interest on any Security of any series and  remaining  unclaimed for one year
after  such  principal  (and  premium,  if any) or  interest  has become due and
payable shall be paid to the Company,  on Company  Request,  or (if then held by
the  Company)  shall be  discharged  from  such  trust;  and the  Holder of such
Security shall thereafter,  as an unsecured  general creditor,  look only to the
Company for payment  thereof,  and all  liability  of the Trustee or such Paying
Agent with  respect to such trust  money,  and all  liability  of the Company as
trustee thereof, shall thereupon cease;  provided,  however, that the Trustee or
such Paying Agent, 
- -------- -------
before  being  required  to make any such  repayment,  may at the expense of the
Company  cause to be  published  once,  in a newspaper  published in the English
language,  customarily published on each Business Day and of general circulation
in the  Borough  of  Manhattan,  The City of New York,  notice  that such  money
remains unclaimed and that, after a date specified  therein,  which shall not be
less than 30 days from the date of such  publication,  any unclaimed  balance of
such money then remaining will be repaid to the Company.

Section 10.4 Corporate Existence.
             -------------------

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

Section 10.5  Waiver of Certain Covenants.
              ---------------------------

     A Board  Resolution  or Officers'  Certificate  or  indenture  supplemental
hereto which  establishes  the terms of a series of Securities  may provide that
specified terms,  provisions and conditions are subject to this Section. In such
event the  Company may omit in any  particular  instance to comply with any such
term,  provision or condition  with respect to the  Securities of such series if
before the time for such compliance the Holders of at least 66 2/3% in principal
amount  of the  Outstanding  Securities  of such  series  shall,  by Act of such
Holders,  either  waive such  compliance  in such  instance or  generally  waive
compliance with such term,  provision or condition.  No such waiver shall extend
to or affect such term, provision or condition except to the extent so expressly
waived,  and until such waiver shall become  effective,  the  obligations of the
Company and the duties of the Trustee in respect of any such term,  provision or
condition shall remain in full force and effect.

Section 10.6 Certificate to Trustee.
             ----------------------

     So long as the same  shall be  required  by the Trust  Indenture  Act,  the
Company will  deliver to the Trustee,  within 120 days of the end of each fiscal
year (or such other time or times as may be required by the Trust  Indenture Act
as then in effect) a  certificate  signed by its  principal  executive  officer,
principal  financial  officer or principal  accounting  officer as to his or her
knowledge of the Company's  compliance  with all conditions and covenants  under
this Indenture (such compliance to be determined without regard to any period of
grace or requirement of notice provided in this Indenture) or in such other form
and with such other signatories as may be required by the Trust Indenture Act as
then in effect.


                                    ARTICLE 11

                            Redemption of Securities

Section 11.1 Applicability of Article.
             ------------------------

     Securities of any series which are redeemable  before their Stated Maturity
shall be  redeemable  in  accordance  with their terms and (except as  otherwise
specified  as  contemplated  by Section  3.1 for  Securities  of any  series) in
accordance with this Article.

Section 11.2 Election to Redeem; Notice to Trustee.
             -------------------------------------

     The election of the Company to redeem any Securities  shall be evidenced by
a Board Resolution. In the case of any redemption at the election of the Company
of all the Securities of any series,  the Company shall,  at least 35 days prior
to the  Redemption  Date fixed by the Company  (unless a shorter period shall be
satisfactory  to the Trustee),  notify the Trustee of such  Redemption  Date. In
case of any  redemption  at the  election  of the  Company  of less than all the
Securities  of any  series,  the  Company  shall,  at least 40 days prior to the
Redemption  Date  fixed  by the  Company  (unless  a  shorter  period  shall  be
satisfactory to the Trustee),  notify the Trustee of such Redemption Date and of
the principal amount of Securities of such series to be redeemed. In the case of
any redemption of securities  prior to the expiration of any restriction on such
redemption  provided  in the  terms  of such  Securities  or  elsewhere  in this
Indenture,  the Company shall furnish the Trustee with an Officers'  Certificate
evidencing  compliance  with such  restriction.  The  Company  may  rescind  its
election to redeem  Securities by notice to the Trustee at any time on or before
20 days  prior  to the  Redemption  Date  (unless  a  shorter  period  shall  be
satisfactory to the Trustee).  To the extent the foregoing rescission provisions
and the rescission  provisions of Section 11.4 are inconsistent  with applicable
book-entry  procedures  of DTC, or any other record owner of  registered  global
securities, such rescission provisions shall be modified to the extent necessary
to permit coordination or conformity with such procedures,  but the minimum time
limitations of the rescission provisions shall not be reduced.

Section 11.3  Selection by Trustee of Securities to Be Redeemed.
              -------------------------------------------------

     If less  than all the  Securities  of like  tenor of any  series  are to be
redeemed,  the  particular  Securities to be redeemed shall be selected not more
than 35 days prior to the  Redemption  Date  (unless a shorter  period  shall be
satisfactory  to  the  Trustee  and  the  Company)  by  the  Trustee,  from  the
Outstanding  Securities of such series not previously called for redemption,  by
such method as the Trustee shall deem fair and appropriate and which may provide
for the selection for  redemption of portions  (equal to the minimum  authorized
denomination for Securities of that series or any integral  multiple thereof) of
the  principal  amount of such  Securities  of a  denomination  larger  than the
minimum authorized denomination for such Securities.

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

     For all purposes of this Indenture,  unless the context otherwise requires,
all  provisions  relating to the redemption of Securities  shall relate,  in the
case of any  Securities  redeemed or to be redeemed only in part, to the portion
of the principal amount of such Securities which has been or is to be redeemed.

Section 11.4 Notice of Redemption.
             --------------------

     Notice of redemption shall be given by first-class  mail,  postage prepaid,
mailed not less than 30 nor more than 60 days prior to the  Redemption  Date, to
each  Holder of  Securities  to be  redeemed,  at his address  appearing  in the
Security Register.

     All notices of redemption shall state:

          (1)   the Redemption Date,

          (2)   the Redemption Price,

          (3)   if less than all the Outstanding Securities of any series are to
be redeemed,  the identification  (and, in the case of partial  redemption,  the
principal amounts) of the particular Securities to be redeemed,
          
          (4) that on the Redemption  Date the Redemption  Price will become due
and payable  upon each such  Security to be redeemed  and, if  applicable,  that
interest thereon will cease to accrue on and after said date,

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

          (6)   if such Securities are convertible or exchangeable other than 
pursuant to Section 3.5, the conversion price and the last date on which such 
Securities may be converted or exchanged,

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

          (8)   if the Company intends to retain its right to rescind the 
redemption, the last date by which notice of rescission of a redemption of 
Securities may be given.

     Notice of  redemption  of  Securities to be redeemed at the election of the
Company, and any notice of the rescission of any such redemption, shall be given
by the Company or, at the Company's  request,  by the Trustee in the name and at
the expense of the Company.  Any notice of rescission of any redemption shall be
given on or before 15 days prior to the applicable Redemption Date.

Section 11.4 Deposit of Redemption Price.
             ---------------------------

     On or before any  Redemption  Date,  the  Company  shall  deposit  with the
Trustee or with a Paying  Agent (or,  if the Company is acting as its own Paying
Agent,  segregate  and hold in trust as provided  in section  10.3) an amount of
money  sufficient to pay on the  Redemption  Date the  Redemption  Price of, and
(except  if the  Redemption  Date shall be an  Interest  Payment  Date)  accrued
interest on, all the Securities which are to be redeemed on that date.

Section 11.6 Securities Payable on Redemption Date.
             -------------------------------------

     Notice of  redemption  having been given as  aforesaid  (and not  rescinded
within the time limitations referred to above), the Securities so to be redeemed
shall, on the Redemption  Date,  become due and payable at the Redemption  Price
therein  specified,  and from and after  such date  (unless  the  Company  shall
default in the  payment  of the  Redemption  Price and  accrued  interest)  such
Securities shall cease to bear interest. Upon surrender of any such Security for
redemption in accordance  with said notice,  such Security  shall be paid by the
Company  at  the  Redemption  Price,  together  with  accrued  interest  to  the
Redemption Date; provided,
                                                              --------
however, that installments of interest whose Stated Maturity is on or
- -------
prior to the Redemption Date shall be payable to the Holders of such Securities,
or one or more  Predecessor  Securities,  registered  as such  at the  close  of
business  on the  relevant  Record  Dates  according  to  their  terms  and  the
provisions of Section 3.7.

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

Section 11.7 Securities Redeemed in Part.
             ---------------------------

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


                                    ARTICLE 12

                                  Sinking Funds

Section 12.1 Applicability of Article.
             -------------------------

     The  provisions of this Article shall be applicable to any sinking fund for
the  retirement  of  Securities  of a series  except as  otherwise  specified as
contemplated by Section 3.1 for Securities of such series.

     The minimum amount of any sinking fund payment provided for by the terms of
Securities  of any series is herein  referred to as a  "mandatory  sinking  fund
payment",  and any payment in excess of such minimum amount  provided for by the
terms of Securities of any series is herein referred to as an "optional  sinking
fund  payment".  If provided for by the terms of Securities  of any series,  the
cash amount of any sinking  fund payment may be subject to reduction as provided
in Section 12.2. Each sinking fund payment shall be applied to the redemption of
securities  of any series as  provided  for by the terms of  Securities  of such
series.

Section 12.2 Satisfaction of Sinking Fund Payments with Securities.
             -----------------------------------------------------

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

Section 12.3 Redemption of Securities for Sinking Fund.
             -----------------------------------------

     Not less  than 60 days  prior to each  sinking  fund  payment  date for any
series of  Securities,  the Company  will  deliver to the  Trustee an  Officers'
Certificate  specifying the amount of the next ensuing  sinking fund payment for
that series pursuant to the terms of that series,  the portion thereof,  if any,
which is to be  satisfied  by payment of cash and the portion  thereof,  if any,
which is to be satisfied by delivering  and crediting  Securities of that series
pursuant to Section 12.2 and will also deliver to the Trustee any  Securities to
be so  delivered.  Not less than 30 days before each such  sinking  fund payment
date the Trustee  shall select the  Securities  to be redeemed upon such sinking
fund  payment  date in the manner  specified in Section 11.3 and cause notice of
the  redemption  thereof  to be given in the name of and at the  expense  of the
Company in the manner  provided in Section  11.4.  Such notice  having been duly
given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Sections 11.6 and 11.7.


                                    ARTICLE 13

defeasance  of the  Securities  of a series  under  Section 13.2 or (b) covenant
defeasance of the Securities of a series under Section 13.3, then the provisions
of such  Section  or  Sections,  as the case  may be,  together  with the  other
provisions of this Article  Thirteen,  shall be applicable to the  Securities of
such  series,  and the  Company  may at its  option  by or  pursuant  to a Board
Resolution, at any time, with respect to the Securities of such series, elect to
have either  Section 13.2 (if  applicable)  or Section 13.3 (if  applicable)  be
applied to the  Outstanding  Securities of such series upon  compliance with the
conditions set forth below in this Article Thirteen.

Section 13.2 Defeasance and Discharge.
             ------------------------

     Upon the Company's exercise of the above option applicable to this Section,
the Company shall be deemed to have been discharged  from its  obligations  with
respect to the Outstanding  Securities of such series on the date the conditions
set forth below are  satisfied  (hereinafter,  "defeasance").  For this purpose,
such  defeasance  means  that the  Company  shall  be  deemed  to have  paid and
discharged the entire indebtedness  represented by the Outstanding Securities of
such  series  and to  have  satisfied  all  its  other  obligations  under  such
Securities and this Indenture  insofar as such Securities are concerned (and the
Trustee,  at the  expense  of the  Company,  shall  execute  proper  instruments
acknowledging  the same),  except for the  following  which shall  survive until
otherwise  terminated  or  discharged  hereunder:  (A) the  rights of Holders of
Outstanding  Securities  of such series to  receive,  solely from the trust fund
described in Section 13.4 and as more fully set forth in such Section,  payments
in  respect of the  principal  of (and  premium,  if any) and  interest  on such

respect to such Securities  under Sections 3.4, 3.5, 3.6, 10.2 and 10.3, (C) the
rights,  powers,  trusts,  duties,  and immunities of the Trustee under Sections
3.5,  3.6,  3.7,  3.9,  4.2,  6.7 and the last  paragraph of Section  10.3,  and
otherwise  the duty of the  Trustee to  authenticate  Securities  of such series
issued on  registration of transfer or exchange,  (D) this Article  Thirteen and
(E) any other Section of this Indenture  contemplated by Section 3.1 to survive.
Subject to compliance with this Article  Thirteen,  the Company may exercise its
option under this Section 13.2  notwithstanding the prior exercise of its option
under Section 13.3 with respect to the Securities of such series.

Section 13.3 Covenant Defeasance.
             -------------------

     Upon the Company's  exercise of the above option applicable to this Section
with respect to the Securities of any series, the Company shall be released from
its obligations under any covenant specified in the Board Resolution,  Officers'
Certificate or supplemental  indenture  establishing  the terms,  conditions and
limitations  with respect to the Outstanding  Securities of such series as being
subject to release pursuant to this Section on and after the date the conditions
set forth below are satisfied  (hereinafter,  "covenant  defeasance").  For this
purpose,  such covenant  defeasance  means that, with respect to the Outstanding
Securities of such series, the Company may omit to comply with and shall have no
liability in respect of any term,  condition or limitation set forth in any such
covenant,  and such  covenant  shall no longer  be  applicable  to the  Company,
whether  directly or indirectly by reason of any reference  elsewhere  herein to
any such Section or by reason of any reference in any such document to any other
provision  herein or in any other document,  but the remainder of this Indenture
and the Securities of any other series shall be unaffected thereby.

Section 13.4 Conditions to Defeasance or Covenant Defeasance.
             -----------------------------------------------

     The following shall be the conditions to application of either Section 13.2
or Section 13.3 to the Outstanding Securities of such series:

following payments,  specifically  pledged as security for, and dedicated solely
to, the benefit of the holders of such  Securities,  (A) money in an amount,  or
(B) U.S. Government Obligations which through the scheduled payment of principal
and interest in respect thereof in accordance with their terms will provide, not
later than one day before the due date of any  payment,  money in an amount,  or
(C) a combination thereof, sufficient, in the opinion of a nationally recognized
firm of  independent  public  accountants  expressed in a written  certification
thereof  delivered  to the  Trustee,  to pay and  discharge,  and which shall be
applied by the Trustee to pay and discharge,  (i) the principal of (and premium,
if any,  on) and each  installment  of principal  of (and  premium,  if any) and
interest on the Outstanding  Securities of such series on the Stated Maturity of
such  principal or  installment  of principal or interest and (ii) any mandatory
sinking  fund  payments or  analogous  payments  applicable  to the  Outstanding
Securities  of such series on the day on which such payments are due and payable
in accordance with the terms of this Indenture and of such Securities.  For this
purpose,  "U.S.  Government  Obligations"  means  securities that are (x) direct
obligations  of the United  States of America  for the payment of which its full
faith  and  credit is  pledged  or (y)  obligations  of a Person  controlled  or
supervised by and acting as an agency or instrumentality of the United States of
America the payment of which is  unconditionally  guaranteed as a full faith and
credit  obligation by the United States of America,  which,  in either case, are
not callable or redeemable at the option of the issuer  thereof,  and shall also
include a depository  receipt issued by a bank (as defined in Section 3(a)(2) of
the  Securities  Act of 1933, as amended) as custodian  with respect to any such
U.S. Government  Obligation or a specific payment of principal of or interest on
any such U.S.  Government  Obligation  held by such custodian for the account of
the holder of such depository receipt, provided that (except as required by law)
such  custodian is not  authorized to make any deduction from the amount payable
to the  holder  of such  depository  receipt  from any  amount  received  by the
custodian in respect of the U.S.  Government  Obligation or the specific payment
of principal of or interest on the U.S. Government  Obligation evidenced by such
depository receipt.

          (b)   (i)  No Event of Default or event which with notice or lapse of
time or both would become an Event of Default with respect to the  Securities of
such series shall have  occurred and be  continuing on the date of such deposit,
and (ii) with respect to a defeasance and discharge  under Section 13.2, no such
Event of Default or event shall have occurred and be continuing under subsection
501(5) or (6) hereof at any time during the period  ending on the 91st day after
the  date of such  deposit  or,  if  longer,  ending  on the day  following  the
expiration of the longest preference period applicable to the Company in respect
of such deposit (it being  understood  that this  condition  shall not be deemed
satisfied until the expiration of such period); provided that in connection with
a defeasance under 
- --------
     Section 13.2 the Company will be released from any  covenants  specified as
being subject to this Article 13 in a Board Resolution or Officers'  Certificate
or  indenture  supplemental  hereto  which  establishes  the term of a series of
Securities,  immediately  upon the making of the deposit  under  subsection  (a)
without  reference  to  the  additional  period  of  time  referred  to in  this
subsection  (ii);  and provided,  further,  however,  that if (x) a bank with an
investment rating
- --------  -------
     of at  least  A by  each of  Standard  &  Poor's  Corporation  and  Moody's
Investors Service,  Inc. shall issue in favor of the Trustee, for the benefit of
the Holders of the Outstanding Securities to be defeased hereunder, an unsecured
letter of credit to guarantee the deposit  referred to in subparagraph (a) above
and (y) the Company  shall  provide to the Trustee an Opinion of Counsel  (which
shall be  nationally  recognized  counsel  experienced  in  bankruptcy  matters)
satisfactory  to the  Trustee to the effect  that no  payments  pursuant  to the
letter of credit to be made for the  benefit of the  Holders of the  Outstanding
Securities  to be  defeased  hereunder  would  be  subject  to  recapture,  as a
preference or otherwise,  by any trustee in bankruptcy of the Company, then this
condition shall be satisfied without regard to the period of time referred to in
subsection (ii) above.

          (c) Such  defeasance  or covenant  defeasance  shall not (i) cause the
Trustee  for the  Securities  of such series to have a  conflicting  interest as
defined in Section 6.8 and for purposes of the Trust  Indenture Act with respect
to any  securities  of the Company or (ii) result in a trust  arising  from such
deposit which constitutes an investment company under the Investment Company Act
of 1940,  as amended (the "40 Act"),  unless it is  registered as such or exempt
from registration under the 40 Act.

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

          (e) Such  defeasance  or  covenant  defeasance  shall  not  cause  any
Securities  of such  series then listed on any  registered  national  securities
exchange under the Securities Exchange Act of 1934, as amended, to be delisted.

          (f) In the case of an election  under Section 13.2,  the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (x) the Company
has received from, or there has been published by, the Internal  Revenue Service
a ruling, or (y) since the date of this Indenture there has been a change in the
applicable  Federal income tax law, in either case to the effect that, and based
thereon  such  opinion  shall  confirm  that,  the  Holders  of the  Outstanding
Securities  of such series will not recognize  income,  gain or loss for Federal
income  tax  purposes  as a result of such  defeasance  and will be  subject  to
Federal income tax on the same amounts, in the same manner and at the same times
as would have been the case if such defeasance had not occurred.

          (g) In the case of an election  under Section 13.3,  the Company shall
have  delivered  to the  Trustee an  opinion  of Counsel to the effect  that the
Holders of the Outstanding  Securities of such series will not recognize income,
gain or loss for  Federal  income  tax  purposes  as a result  of such  covenant
defeasance and will be subject to Federal income tax on the same amounts, in the
same  manner and at the same times as would have been the case if such  covenant
defeasance had not occurred.

          (h) Such  defeasance  or  covenant  defeasance  shall be  effected  in
compliance  with any additional  terms,  conditions or limitations  which may be
imposed on the Company in connection therewith pursuant to Section 3.1.

          (i) The  Company  shall have  delivered  to the  Trustee an  Officers'
Certificate and an Opinion of Counsel each stating that all conditions precedent
provided  for  relating  to either  the  defeasance  under  Section  13.2 or the
covenant  defeasance  under Section 13.3 (as the case may be) have been complied
with.

Section 13.5 Deposited Money and U.S. Government Obligations to
             be Held in Trust; Other Miscellaneous Provisions.
             -------------------------------------------------

     Subject to the  provisions of the last paragraph of Section 10.3, all money
and U.S. Government  Obligations (including the proceeds thereof) deposited with
the Trustee pursuant to Section 13.4 in respect of the Outstanding Securities of
such series  shall be held in trust and applied by the  Trustee,  in  accordance
with the  provisions  of such  Securities  and this  Indenture,  to the payment,
either directly or through any Paying Agent (including the Company acting as its
own  paying  agent)  as the  Trustee  may  determine,  to the  Holders  of  such
Securities,  of all sums due and to become due  thereon in respect of  principal
(and premium,  if any) and interest,  but such money need not be segregated from
other funds except to the extent required by law.

     The Company  shall pay and  indemnify  the Trustee  against any tax, fee or
other  charge  imposed on or assessed  against the U.S.  Government  Obligations
deposited  pursuant to Section 13.4 or the  principal  and interest  received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of the Outstanding Securities of such series.

     Anything in this  Article  Thirteen to the  contrary  notwithstanding,  the
Trustee  shall  deliver  or pay to the  Company  from time to time upon  Company
Request  any money or U.S.  Government  Obligations  held by it as  provided  in
Section  13.4  which,  in  the  opinion  of  a  nationally  recognized  firm  of
independent  public  accountants  expressed in a written  certification  thereof
delivered to the Trustee,  are in excess of the amount  thereof which would then
be required  to be  deposited  to effect an  equivalent  defeasance  or covenant
defeasance.

Section Reinstatement.

     If the Trustee or Paying  Agent is unable to apply any money or  securities
in  accordance  with  Section  13.5 of this  Indenture,  by  reason of any legal
proceeding  or by reason of any order or judgment  of any court or  governmental
authority enjoining,  restraining or otherwise prohibiting such application, the
Company's  obligations under this Indenture and the Securities of the applicable
series  shall be  revived  and  reinstated  as though no  deposit  had  occurred
pursuant  to Section  13.4 of this  Indenture  until such time as the Trustee or
Paying Agent is permitted to apply all such money or  securities  in  accordance
with Section 13.5 of this Indenture;  provided that, if the Company has made any
payment of  principal  ------- of or interest on any  Securities  because of the
reinstatement of its obligations,  the Company shall be subrogated to the rights
of the Holders of such  Securities  to receive  such  payment  from the money or
securities held by the Trustee or Paying Agent.

                                    ARTICLE 14

     No recourse  under or upon any  obligation,  covenant or  agreement of this

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