     terms and conditions (including any certification requirements) upon which
     any such interest payment received by a clearing organization will be

                                       15
<PAGE>
 
     and (y) the terms upon which interests in such temporary Debt Security in
     global form may be exchanged for interests in a permanent Global Note or
     for definitive Debt Securities of the series and the terms upon which
     interests in a permanent Global Note, if any, may be exchanged for
     definitive Debt Securities of the series;

          (17) whether the Debt Securities of the series shall be issued in
     whole or in part in the form of one or more Global Notes and, in such case,
     the U.S. Depositary or any Common Depositary for such Global Note or Notes;
     and if the Debt Securities of the series are issuable only as Registered
     Securities, the manner in which and the circumstances under which Global

     Registered Securities in definitive form, if other than, or in addition to,
     the manner and circumstances specified in Section 3.04(c); and

          (18)  the nature and terms of any security applicable to the Offered
     Securities;

          (19)   any other terms of the series (which terms shall not be
     inconsistent with the provisions of this Indenture).

          All Debt Securities of any one series shall be substantially identical
except as to denomination, rate of interest, Stated Maturity and the date from
which interest, if any, shall accrue, which, as set forth above, may be
determined by the Company from time to time as to Debt Securities of a series if
so provided in or established pursuant to the authority granted in a Board
Resolution or in any such indenture supplemental hereto, and except as may
otherwise be provided in or pursuant to such Board Resolution and (subject to
Section 3.03) set forth in such Officers' Certificate, or in any such indenture
supplemental hereto.  All Debt Securities of any one series need not be issued
at the same time, and unless otherwise provided, a series may be reopened for

Certificate setting forth the terms of the series.

          Section 3.02.  Denominations.  In the absence of any specification

                                       16
<PAGE>
 
          Section 3.03.  Execution, Authentication, Delivery and Dating.  The
Debt Securities and the Coupons, if any, of any series shall be executed on
behalf of the Company by its Chairman, a Vice Chairman, its President, one of
its Vice Presidents or its Treasurer, under its corporate seal reproduced
thereon and attested by its Secretary or one of its Assistant Secretaries.  The
signature of any of these officers may be manual or facsimile.

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

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Debt Securities, with appropriate
Coupons, if any, of any series, executed by the Company, to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Debt Securities and Coupons and the Trustee in accordance with
the Company Order shall authenticate and deliver such Debt Securities and
Coupons; provided, however, that, in connection with its sale during the
"restricted period" (as defined in Section 1.163-5(c)(2)(i)(D)(7) of the United
States Treasury Regulations), no Bearer Security shall be mailed or otherwise
delivered to any location in the United States; and provided, further, that a
Bearer Security (other than a temporary Global Note in bearer form) may be
delivered outside the United States in connection with its original issuance
only if the Person entitled to receive such Bearer Security shall have furnished
to the Euro-clear Operator or to CEDEL a certificate substantially in the form
set forth in Exhibit A to this Indenture.  If all the Debt Securities of any one
series are not to be issued at one time and if a Board Resolution or
supplemental indenture relating to such series shall so permit, such Company
Order may set forth procedures acceptable to the Trustee for the issuance of
such Debt Securities, such as interest rate, Stated Maturity, date of issuance
and date from which interest, if any, shall accrue.  If any Debt Security shall
be represented by a permanent Global Note, then, for purposes of this Section
and Section 3.04, the notation of a beneficial owner's interest therein upon
original issuance of such Debt Security or upon exchange of a portion of a
temporary Global Note shall be deemed to be delivery in connection with the
original issuance of such beneficial owner's interest in such permanent Global
Note.  Except as permitted by Section 3.06 or 3.07, the Trustee shall not
authenticate and deliver any Bearer Security unless all Coupons for interest
then matured have been detached and cancelled.

          The Trustee shall be entitled to receive, and (subject to Section
6.01) shall be fully protected in relying upon, prior

                                       17
<PAGE>
 
to the authentication and delivery of the Debt Securities and Coupons of such
series, (i) the supplemental indenture or the Board Resolution by or pursuant to
which the form and terms of such Debt Securities and Coupons have been approved
and (ii) an Opinion of Counsel substantially to the effect that:

          (1) all instruments furnished by the Company to the Trustee in
     connection with the authentication and delivery of such Debt Securities and
     Coupons conform to the requirements of this Indenture and constitute
     sufficient authority hereunder for the Trustee to authenticate and deliver
     such Debt Securities and Coupons;

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

          (3) in the event that the forms or terms of such Debt Securities and
     Coupons have been established in a supple-mental indenture, the execution
     and delivery of such supplemental indenture has been duly authorized by all
     necessary corporate action of the Company, such supplemental indenture has
     been duly executed and delivered by the Company and, assuming due
     authorization, execution and delivery by the Trustee, is a valid and
     binding obligation enforceable against the Company in accordance with its
     terms, except as affected by bankruptcy, insolvency, fraudulent conveyance,
     reorganization, moratorium and other similar laws relating to or affecting
     creditors' rights generally, general equitable principles (whether
     considered in a proceeding in equity or at law) and subject to such other
     exceptions as counsel shall request and as to which the Trustee shall not
     reasonably object;

          (4) the execution and delivery of such Debt Securities and Coupons
     have been duly authorized by all necessary corporate action of the Company
     and such Debt Securities and Coupons have been duly executed by the Company
     and, assuming due authentication by the Trustee and delivery by the
     Company, are valid and binding obligations enforceable against the Company
     in accordance with their terms, entitled to the benefit of the Indenture,
     except as affected by bankruptcy, insolvency, fraudulent conveyance,
     reorganization, moratorium and other similar laws relating to or affecting
     creditors' rights generally, general equitable principles (whether
     considered in a proceeding in equity or at law) and subject to such other
     exceptions as counsel shall request and as to which the Trustee shall not
     reasonably object; and

          (5) the amount of Debt Securities Outstanding of such series, together
     with the amount of such Debt Securities, does not exceed any limit
     established under the terms of

                                       18
<PAGE>
 
     this Indenture on the amount of Debt Securities of such series that may be
     authenticated and delivered.

          The Trustee shall not be required to authenticate such Debt Securities
and Coupons if the issuance of such Debt Securities and Coupons pursuant to this
Indenture will affect the Trustee's own rights, duties or immunities under the
Debt Securities and this Indenture in a manner which is not reasonably
acceptable to the Trustee.

          Each Registered Security shall be dated the date of its
authentication.  Each Bearer Security (including any temporary or permanent or
other definitive Bearer Security in global form) shall be dated as of the date
of original issuance of the first Debt Security of such series to be issued,
except as otherwise provided pursuant to Section 3.01 with respect to the Bearer
Securities of any series.

          No Debt Security shall be entitled to any benefit under this Indenture
or be valid or obligatory for any purpose unless there appears on such Debt
Security a certificate of authentication substantially in one of the forms
provided for herein duly executed by the Trustee or by an Authenticating Agent,
and such certificate upon any Debt Security shall be conclusive evidence, and
the only evidence, that such Debt Security has been duly authenticated and
delivered hereunder and is entitled to the benefits of this Indenture.
Notwithstanding the foregoing, if any Debt Security shall have been duly
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Debt Security to the Trustee for cancellation
as provided in Section 3.08 together with a written statement (which need not
comply with Section 16.05) stating that such Debt Security has never been issued
and sold by the Company, for all purposes of this Indenture such Debt Security
shall be deemed never to have been authenticated and delivered hereunder and
shall never be entitled to the benefits of this Indenture.

          Section 3.04.  Temporary Debt Securities; Exchange of Temporary Global
Notes for Definitive Bearer Securities; Global Notes Representing Registered
Securities.  (a)  Pending the preparation of definitive Registered Securities of
any series, the Company may execute, and upon Company Order the Trustee shall
authenticate and deliver, temporary Registered Securities which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination for Registered Securities of such series, substantially of the
tenor of the definitive Registered Securities in lieu of which they are issued
and with such appropriate insertions, omissions, substitutions and other
variations as the officers executing such Registered Securities may determine,
as conclusively evidenced by their execution of such Registered Securities.
Every such temporary Registered Security shall be executed by the Company and
shall be authenticated and delivered by the Trustee upon the same

                                       19
<PAGE>
 
conditions and in substantially the same manner, and with the same effect, as
the definitive Registered Securities in lieu of which they are issued.  In the
case of any series issuable as Bearer Securities, such temporary Debt Securities
may be in global form, representing such of the Outstanding Debt Securities of
such series as shall be specified therein.

          Except in the case of temporary Debt Securities in global form (which
shall be exchanged in accordance with the provisions of the following
paragraphs), if temporary Debt Securities of any series are issued, the Company
will cause definitive Debt Securities of such series to be prepared without
unreasonable delay.  After the preparation of definitive Debt Securities of such
series, the temporary Debt Securities of such series shall be exchangeable for
definitive Debt Securities of such series, of a like Stated Maturity and with
like terms and provisions, upon surrender of the temporary Debt Securities of
such series at the office or agency of the Company in a Place of Payment for
such series, without charge to the Holder, except as provided in Section 3.05 in
connection with a transfer.  Upon surrender for cancellation of any one or more
temporary Debt Securities of any series (accompanied by any unmatured Coupons),
the Company shall execute and the Trustee shall authenticate and deliver in
exchange therefor a like principal amount of definitive Debt Securities of the
same series of authorized denominations and of a like Stated Maturity and like
terms and provisions; provided, however, that no definitive Bearer Security
shall be delivered in exchange for a temporary Registered Security; and
provided, further, that a definitive Bearer Security (including a permanent
Bearer Security in global form) shall be delivered in exchange for a temporary
Bearer Security only in compliance with the conditions set forth in Section
3.03.  Until so exchanged, the temporary Registered Securities of any series
shall in all respects be entitled to the same benefits under this Indenture as
definitive Registered Securities of such series.

          (b) Unless otherwise specified pursuant to Section 3.01, all Bearer
Securities of a series shall be initially issued in the form of a single
temporary Bearer Security in global form (a "temporary Global Note").  The
Company shall execute, and upon Company Order the Trustee shall authenticate,
any temporary Global Note and any permanent Bearer Security in global form (as
described below, a "permanent Global Note") upon the same conditions and in
substantially the same manner, and with the same effect, as definitive Bearer
Securities, and the temporary or permanent Global Note, as the case may be,
shall, unless otherwise specified therein, be delivered by the Trustee to the
London office of a depositary or common depositary (the "Common Depositary"),
for the benefit of the Euro-clear Operator or CEDEL, as the case may be, for
credit to the account of the Company (in the case of sales of Bearer Securities
by the Company directly to investors) or the managing underwriter (in the case
of sales of Bearer Securities by the Company to underwriters) or

                                       20
<PAGE>
 
such other accounts as the Company or the managing underwriter, respectively,
may direct.

          On or after the date specified in or determined pursuant to the terms
of any temporary Global Note, which (subject to any applicable laws and
regulations) shall be at least 40 days after the issue date of a temporary
Global Note (for purposes of this Section 3.04(b), the "Exchange Date"), the
Debt Securities represented by such temporary Global Note may be exchanged for
definitive Debt Securities (subject to the second succeeding paragraph) or Debt
Securities to be represented thereafter by one or more permanent Global Notes in
definitive form without interest coupons.  On or after the Exchange Date such
temporary Global Note shall be surrendered by the Common Depositary to the
Trustee, as the Company's agent for such purpose, at its principal office in
London (or at such other place specified outside the United States pursuant to
Section 3.01) and following such surrender, the Trustee shall (1) endorse the
temporary Global Note to reflect the reduction of its principal amount by an
equal aggregate principal amount of such Debt Security, (2) endorse the
applicable permanent Global Note, if any, to reflect the amount, or an increase
in the amount, of Debt Securities represented thereby, (3) manually authenticate
such definitive Debt Securities (including any permanent Global Note), (4)
deliver such definitive Debt Securities to the Holder thereof or, if such
definitive Debt Security is a permanent Global Note, deliver such permanent
Global Note to the Common Depositary to be held outside the United States for
the accounts of the Euro-clear Operator or CEDEL, as the case may be, for credit
to the respective accounts at the Euro-clear Operator or CEDEL, as the case may
be, designated by or on behalf of the beneficial owners of such Debt Securities
(or to such other accounts as they may direct) and (5) redeliver such temporary
Global Note to the Common Depositary, unless such temporary Global Note shall
have been cancelled in accordance with Section 3.08 hereof; provided, however,
that, unless otherwise specified in such temporary Global Note, upon such
presentation by the Common Depositary, such temporary Global Note shall be
accompanied by a certificate dated the Exchange Date or a subsequent date and
signed by the Euro-clear Operator, as to the portion of such temporary Global
Note held for its account then to be exchanged for definitive Debt Securities
(including any permanent Global Note), and a certificate dated the Exchange Date
or a subsequent date and signed by CEDEL, as to the portion of such temporary
Global Note held for its account then to be exchanged for definitive Debt
Securities (including any permanent Global Note), each substantially in the form
set forth in Exhibit B to this Indenture.  Each certificate substantially in the
form of Exhibit B hereto of the Euro-clear Operator or CEDEL, as the case may
be, shall be based on certificates of the account holders listed in the records
of the Euro-clear Operator or CEDEL, as the case may be, as being entitled to
all or any portion of the applicable temporary Global Note.  An account holder
of the Euro-clear Operator or CEDEL, as the case may be,

                                       21
<PAGE>
 
desiring to effect the exchange of an interest in a temporary Global Note for an
interest in definitive Debt Securities (including any permanent Global Note)
shall instruct the Euro-clear Operator or CEDEL, as the case may be, to request
such exchange on its behalf and shall deliver to the Euro-clear Operator or
CEDEL, as the case may be, a certificate substantially in the form of Exhibit A
hereto and dated no earlier than 10 days prior to the Exchange Date.  Until so
exchanged, temporary Global Notes shall in all respects be entitled to the same
benefits under this Indenture as definitive Debt Securities (including any
permanent Global Note) of the same series authenticated and delivered hereunder,
except as to payment of interest, if any.

          The delivery to the Trustee by the Euro-clear Operator or CEDEL of any
certificate substantially in the form of Exhibit B hereto may be relied upon by
the Company and the Trustee as conclusive evidence that a corresponding
certificate or certificates has or have been delivered to the Euro-clear
Operator or CEDEL, as the case may be, pursuant to the terms of this Indenture.

          On or prior to the Exchange Date, the Company shall deliver to the
Trustee definitive Debt Securities in an aggregate principal amount equal to the
principal amount of such temporary Global Note, executed by the Company.  At any
time, on or after the Exchange Date, upon 30 days' notice to the Trustee by the
Euro-clear Operator or CEDEL, as the case may be, acting at the request of or on
behalf of the beneficial owner, a Debt Security represented by a temporary
Global Note or a permanent Global Note, as the case may be, may be exchanged, in
whole or from time to time in part, for definitive Debt Securities without
charge and the Trustee shall authenticate and deliver, in exchange for each
portion of such temporary Global Note or such permanent Global Note, an equal
aggregate principal amount of definitive Debt Securities of the same series of
authorized denominations and of a like Stated Maturity and with like terms and
conditions, as the portion of such temporary Global Note or such permanent
Global Note to be exchanged, which, unless the Debt Securities of the series are
not issuable both as Bearer Securities and as Registered Securities, as
contemplated by Section 3.01, shall be in the form of Bearer Securities or
Registered Securities, or any combination thereof, as shall be specified by the
beneficial owner thereof; provided, however, that definitive Bearer Securities
shall be delivered in exchange for a portion of the temporary Global Note or the
permanent Global Note only in compliance with the requirements of the second
preceding paragraph.  On or prior to the forty-fifth day following receipt by
the Trustee of such notice with respect to a Debt Security, or, if such day is
not a Business Day, the next succeeding Business Day, the temporary Global Note
or the permanent Global Note, as the case may be, shall be surrendered by the
Common Depositary to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or from time to time in part,

                                       22
<PAGE>
 
for definitive Debt Securities without charge following such surrender, upon the
request of the Euro-clear Operator or CEDEL, as the case may be, and the Trustee
shall (1) endorse the applicable temporary Global Note or the permanent Global
Note to reflect the reduction of its principal amount by the aggregate principal
amount of such Debt Security, (2) cause the terms of such Debt Security and
Coupons, if any, to be entered on a definitive Debt Security, (3) manually
authenticate such definitive Debt Security, and (4) if a Bearer Security is to
be delivered, deliver such definitive Debt Security outside the United States to
the Euro-clear Operator or CEDEL, as the case may be, for or on behalf of the
beneficial owner thereof, in exchange for a portion of such temporary Global
Note or the permanent Global Note.

          Unless otherwise specified in such temporary Global Note or the
permanent Global Note, any such exchange shall be made free of charge to the
beneficial owners of such temporary Global Note or the permanent Global Note,
except that a Person receiving definitive Debt Securities must bear the cost of
insurance, postage, transportation and the like in the event that such Person
does not take delivery of such definitive Debt Securities in person at the
offices of the Euro-clear Operator or CEDEL.  Definitive Securities in bearer
form to be delivered in exchange for any portion of a temporary Global Note or
the permanent Global Note shall be delivered only outside the United States.
Notwithstanding the foregoing, in the event of redemption or acceleration of all
or any part of a temporary Global Note prior to the Exchange Date, a permanent
Global Note or definitive Bearer Securities, as the case may be, will not be
issuable in respect of such temporary Global Note or such portion thereof, and
payment thereon will instead be made as provided in such temporary Global Note.

          Until exchanged in full as hereinabove provided, any temporary Global
Note or the permanent Global Note shall in all respects be entitled to the same
benefits under this Indenture as definitive Debt Securities of the same series
and tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 3.01, interest payable on such temporary
Global Note on an Interest Payment Date for Debt Securities of such series
occurring prior to the applicable Exchange Date shall be payable to the Euro-
clear Operator or CEDEL on such Interest Payment Date upon delivery by the Euro-
clear Operator or CEDEL to the Trustee of a certificate or certificates
substantially in the form set forth in Exhibit B to this Indenture, for credit
without further interest on or after such Interest Payment Date to the
respective accounts of the Persons who are the beneficial owners of such
temporary Global Note on such Interest Payment Date and who have each delivered
to the Euro-clear Operator or CEDEL, as the case may be, a certificate
substantially in the form set forth in Exhibit A to this Indenture.

                                       23
<PAGE>
 
          Any definitive Bearer Security authenticated and delivered by the
Trustee in exchange for a portion of a temporary Global Note or the permanent
Global Note shall not bear a coupon for any interest which shall theretofore
have been duly paid by the Trustee to the Euro-clear Operator or CEDEL, or by
the Company to the Trustee in accordance with the provisions of this Section
3.04.

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

          (c) If the Company shall establish pursuant to Section 3.01 that the
Registered Securities of a series are to be issued in whole or in part in the
form of one or more Global Notes, then the Company shall execute and the Trustee
shall, in accordance with Section 3.03 and the Company Order with respect to
such series, authenticate and deliver one or more Global Notes in temporary or
permanent form that (i) shall represent and shall be denominated in an amount
equal to the aggregate principal amount of the Outstanding Debt Securities of
such series to be represented by one or more Global Notes, (ii) shall be
registered in the name of the U.S. Depositary for such Global Note or Notes or
the nominee of such depositary, and (iii) shall bear a legend substantially to
the following effect:  "This Debt Security may not be transferred except as a
whole by the Depositary to a nominee of the Depositary or by a nominee of the
Depositary to the Depositary or another nominee of the Depositary or by the
Depositary or any such nominee to a successor Depositary or a nominee of such
successor Depositary, unless and until this Debt Security is exchanged in whole
or in part for Debt Securities in definitive form."

          Notwithstanding any other provision of this Section or Section 3.05,
unless and until it is exchanged in whole or in part for Registered Securities
in definitive form, a Global Note representing all or a portion of the
Registered Securities of a series may not be transferred except as a whole by
the U.S. Depositary for such series to a nominee of such depositary or by a
nominee of such depositary to such depositary or another nominee of such
depositary or by such depositary or any such nominee to a successor U.S.
Depositary for such series or a nominee of such successor depositary.

          If at any time the U.S. Depositary for the Debt Securities of a series
notifies the Company that it is unwilling or unable to continue as U.S.
Depositary for the Debt Securities

                                       24
<PAGE>
 
of such series or if at any time the U.S. Depositary for Debt Securities of a
series shall no longer be a clearing agency registered and in good standing
under the Securities Exchange Act of 1934, as amended, or other applicable
statute or regulation, the Company shall appoint a successor U.S. Depositary
with respect to the Debt Securities of such series.  If a successor U.S.
Depositary for the Debt Securities of such series is not appointed by the
Company within 90 days after the Company receives such notice or becomes aware
of such condition, the Company will execute, and the Trustee, upon receipt of a
Company Order for the authentication and delivery of definitive Debt Securities
of such series, will authenticate and deliver, Registered Securities of such
series in definitive form in an aggregate principal amount equal to the
principal amount of the Global Note or Notes representing such series in
exchange for such Global Note or Notes.

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

          If the Registered Securities of any series shall have been issued in
the form of one or more Global Notes and if an Event of Default with respect to
the Debt Securities of such series shall have occurred and be continuing, the
Company will promptly execute, and the Trustee, upon receipt of a Company Order
for the authentication and delivery of definitive Debt Securities of such
series, will authenticate and deliver, Registered Securities of such series in
definitive form and in an aggregate principal amount equal to the principal
amount of the Global Note or Notes representing such series in exchange for such
Global Note or Notes.

          If specified by the Company pursuant to Section 3.01 with respect to
Registered Securities of a series, the U.S. Depositary for such series of
Registered Securities may surrender a Global Note for such series of Debt
Securities in exchange in whole or in part for Registered Securities of such
series in definitive form on such terms as are acceptable to the Company and
such depositary.  Thereupon, the Company shall execute and the Trustee shall
authenticate and deliver, without charge:

          (i) to each Person specified by the U.S. Depositary a new Registered
     Security or Securities of the same series, of any authorized denomination
     as requested by such Person in

                                       25
<PAGE>
 
     an aggregate principal amount equal to and in exchange for such Person's
     beneficial interest in the Global Note; and

          (ii) to the U.S. Depositary a new Global Note in a denomination equal
     to the difference, if any, between the principal amount of the surrendered
     Global Note and the aggregate principal amount of Registered Securities in
     definitive form delivered to Holders thereof.

          Upon the exchange of a Global Note for Registered Securities in
definitive form, such Global Note shall be cancelled by the Trustee.  Debt
Securities issued in exchange for a Global Note pursuant to this subsection (c)
shall be registered in such names and in such authorized denominations as the
U.S. Depositary for such Global Note, pursuant to instructions from its direct
or indirect participants or otherwise, shall instruct the Trustee.  The Trustee
shall deliver such Debt Securities to the Persons in whose names such Debt
Securities are so registered.

          Section 3.05. Registration, Transfer and Exchange. (a) The Company
shall cause to be kept at the Corporate Trust Office of the Trustee a register
(the registers maintained in such office and in any other office or agency of
the Company in a Place of Payment being herein sometimes collectively referred
to as the "Security Register") in which, subject to such reasonable regulations
as it may prescribe, the Company shall provide for the registration of
Registered Securities and of transfers and exchanges of Registered Securities.
The Trustee is hereby appointed "Security Registrar" for the purpose of
registering Registered Securities and registering transfers and exchanges of
Registered Securities as herein provided; provided, however, that the Company
may appoint co-Security Registrars.

          Upon surrender for registration of transfer of any Registered Security
of any series at the office or agency of the Company maintained for such
purpose, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee, one or more new Registered
Securities of the same series of like aggregate principal amount of such
denominations as are authorized for Registered Securities of such series and of
a like Stated Maturity and with like terms and conditions.

          Except as otherwise provided in Section 3.04 and this Section 3.05, at
the option of the Holder, Registered Securities of any series may be exchanged
for other Registered Securities of the same series of like aggregate principal
amount and of a like Stated Maturity and with like terms and conditions, upon
surrender of the Registered Securities to be exchanged at such office or agency.
Whenever any Registered Securities are surrendered for exchange, the Company
shall execute, and the

                                       26
<PAGE>
 
Trustee shall authenticate and deliver, the Registered Securities which the
Holder making the exchange is entitled to receive.

          (b) If and to the extent specified pursuant to Section 3.01, the
provisions of this Section 3.05(b) shall be applicable to Debt Securities of any
series which are Bearer Securities.  At the option of the Holder thereof, to the
extent permitted by law, any Bearer Security of any series which by its terms is
registrable as to principal and interest may be exchanged for a Registered
Security of such series of like aggregate principal amount and of a like Stated
Maturity and with like terms and conditions upon surrender of such Bearer
Security at the Corporate Trust Office or at any other office or agency of the
Company designated pursuant to Section 3.01 for the purpose of making any such
exchanges.  Any Coupon Security surrendered for exchange shall be surrendered
with all unmatured Coupons and any matured Coupons in default attached thereto.
If the Holder of a Bearer Security is unable to produce any such unmatured
Coupon or Coupons or matured Coupon or Coupons in default, such exchange may be
effected if the Bearer Securities are accompanied by payment in funds acceptable
to the Company in an amount equal to the face amount of such missing Coupon or
Coupons, or the surrender of such missing Coupon or Coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless.  If
thereafter the Holder of such Bearer Security shall surrender to any Paying
Agent any such missing Coupon in respect of which such a payment shall have been
made, such Holder shall be entitled to receive the amount of such payment;
provided, however, that except as otherwise provided in Section 12.03, interest
represented by Coupons shall be payable only upon presentation and surrender of
those Coupons at an office or agency located outside the United States.

          Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such office or agency in exchange for a Registered
Security of the same series and of a like Stated Maturity and with like terms
and conditions after the close of business at such office or agency on (i) any
Regular Record Date and before the opening of business at such office or agency
on the relevant Interest Payment Date, or (ii) any Special Record Date and
before the opening of business at such office or agency on the related proposed
date for payment of Defaulted Interest, such Bearer Security shall be
surrendered without the Coupon relating to such Interest Payment Date or
proposed date for payment, as the case may be (or, if such Coupon is so
surrendered with such Bearer Security, such Coupon shall be returned to the
Person so surrendering the Bearer Security), and interest or Defaulted Interest,
as the case may be, will not be payable on such Interest Payment Date or
proposed date for payment, as the case may be, in respect of the Registered
Security issued in exchange for such Bearer Security, but will be payable only
to the Holder of such Coupon when due in accordance with the provisions of this
Indenture.  The Company shall

                                       27
<PAGE>
 
execute, and the Trustee shall authenticate and deliver, the Registered Security
or Securities which the Holder making the exchange is entitled to receive.

          Notwithstanding the foregoing, the exchange of Bearer Securities for
Registered Securities will be subject to the provisions of United States income
tax laws and regulations applicable to Debt Securities in effect at the time of
such exchange.

          (c)  Except as otherwise specified pursuant to Section 3.01, in no
event may Registered Securities, including Registered Securities received in
exchange for Bearer Securities, be exchanged for Bearer Securities.

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

          Every Registered Security presented or surrendered for transfer or
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 will be made for any transfer or exchange of Debt
Securities except as provided in Section 3.04(b) or 3.06. 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, transfer or
exchange of Debt Securities, other than those expressly provided in this
Indenture to be made at the Company's own expense or without expense or without
charge to the Holders.

          The Company shall not be required (i) to register, transfer or
exchange Debt Securities of any series during a period beginning at the opening
of business 15 days before the day of the transmission of a notice of redemption
of Debt Securities of such series selected for redemption under Section 13.03
and ending at the close of business on the day of such transmission, or (ii) to
register, transfer or exchange any Debt Security so selected for redemption in
whole or in part, except the unredeemed portion of any Debt Security being
redeemed in part.

          Section 3.06.  Mutilated, Destroyed, Lost and Stolen Debt Securities.
If (i) any mutilated Debt Security or any mutilated Coupon with the Coupon
Security to which it appertains (and all unmatured Coupons attached thereto) is
surrendered to the Trustee at its Corporate Trust Office (in the case of
Registered Securities) or at its London office (in the case of

                                       28
<PAGE>
 
Bearer Securities), or (ii) the Company and the Trustee receive evidence to
their satisfaction of the destruction, loss or theft of any Debt Security or any
Coupon, and there is delivered to the Company and the Trustee such security or
indemnity as may be required by them to save each of them and any Paying Agent
harmless, and neither the Company nor the Trustee receives notice that such Debt
Security or Coupon has been acquired by a bona fide purchaser, then the Company
shall execute and upon Company Request the Trustee shall authenticate and
deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
stolen Debt Security or in exchange for the Coupon Security to which such
mutilated, destroyed, lost or stolen Coupon appertained, a new Debt Security of
the same series of like Stated Maturity and with like terms and conditions and
like principal amount, bearing a number not contemporaneously Outstanding, and,
in the case of a Coupon Security, with such Coupons attached thereto that
neither gain nor loss in interest shall result from such exchange or
substitution.

          In case any such mutilated, destroyed, lost or stolen Debt Security or
Coupon has become or is about to become due and payable, the Company in its
discretion may, instead of issuing a new Debt Security, pay the amount due on
such Debt Security or Coupon in accordance with its terms; provided, however,
that principal of (and premium, if any) and any interest on Bearer Securities
shall, except as otherwise provided in Section 12.03, be payable only at an
office or agency located outside the United States and, unless otherwise
specified as contemplated by Section 3.01 or except as otherwise provided in
this Section 3.06, any interest on Bearer Securities shall be payable only upon
presentation and surrender of the Coupons appertaining thereto.

          Upon the issuance of any new Debt 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 respect thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

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

          Section 3.07.  Payment of Interest; Interest Rights Preserved.  (a)
Interest on any Registered Security which is payable and is punctually paid or
duly provided for on any Interest Payment Date shall be paid to the Person in
whose name such Registered Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such
interest, notwithstanding the cancellation of such Registered Security upon any
transfer or exchange subsequent to the Regular Record Date.  Unless otherwise
specified as contemplated by Section 3.01 with respect to the Debt Securities of
any series, payment of interest on Registered Securities shall be made at the
place or places specified pursuant to Section 3.01 or, at the option of the
Company, by check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register or, if provided pursuant to
Section 3.01, by wire transfer to an account designated by the Registered
Holder.

          (b) Interest on any Coupon Security which is payable and is punctually
paid or duly provided for on any Interest Payment Date shall be paid to the
Holder of the Coupon which has matured on such Interest Payment Date upon
surrender of such Coupon on such Interest Payment Date at the principal London
office of the Trustee or at such other Place of Payment outside the United
States specified pursuant to Section 3.01.

          Interest on any Bearer Security (other than a Coupon Security) which
is payable and is punctually paid or duly provided for on any Interest Payment
Date shall be paid to the Holder of the Bearer Security upon presentation of
such Bearer Security and notation thereon on such Interest Payment Date at the
principal London office of the Trustee or at such other Place of Payment outside
the United States specified pursuant to Section 3.01.  If such payment at the
offices of all Paying Agents outside the United States becomes illegal or is
effectively precluded because of the imposition of exchange controls or similar
restrictions on the full payment or receipt of such amounts in Dollars, the
Company will appoint an office or agent in the United States at which such
payment may be made.  Except as provided in this paragraph, no payment on any
Bearer Security or Coupon will be made by mail to an address in the United
States or by wire transfer to an account in the United States.

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

                                       30
<PAGE>
 
               (1) The Company may elect to make payment of any Defaulted
          Interest to the Persons in whose names such Registered Securities (or
          their respective Predecessor Securities) are registered at the close
          of business on a Special Record Date for the payment of such Defaulted
          Interest, which shall be fixed in the following manner.  The Company
          shall notify the Trustee in writing of the amount of Defaulted
          Interest proposed to be paid on each such Registered Security and the
          date of the proposed payment, and at the same time the Company shall
          deposit with the Trustee an amount of money equal to the aggregate
          amount proposed to be paid in respect of such Defaulted Interest or
          shall make arrangements satisfactory to the Trustee for such deposit
          prior to the date of the proposed payment, such money when deposited
          to be held in trust for the benefit of the Persons entitled to such
          Defaulted Interest as in this clause provided.  Thereupon the Trustee
          shall fix a Special Record Date for the payment of such Defaulted
          Interest which date shall be not more than 15 days and not less than
          10 days prior to the date of the proposed payment and not less than 10
          days after the receipt by the Trustee of the notice of the proposed
          payment.  The Trustee shall promptly notify the Company of such
          Special Record Date and, in the name and at the expense of the
          Company, shall cause notice of the proposed payment of such Defaulted
          Interest and the Special Record Date therefor to be mailed, first-
          class postage prepaid, to the Holders of such Registered Securities at
          their addresses as they appear in the Security Register, not less than
          10 days prior to such Special Record Date.  Notice of the proposed
          payment of such Defaulted Interest and the Special Record Date
          therefor having been mailed as aforesaid, such Defaulted Interest
          shall be paid to the Persons in whose names such Registered Securities
          (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 (2).

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

          (d) Any Defaulted Interest payable in respect of Bearer Securities of
any series shall be payable pursuant to such procedures as may be satisfactory
to the Trustee in such manner that there is no discrimination between the
Holders of Registered

                                       31
<PAGE>
 
Securities (if any) and Bearer Securities of such series, and notice of the
payment date therefor shall be given by the Trustee, in the name and at the
expense of the Company, in the manner provided in Section 16.03 not more than 25
days and not less than 20 days prior to the date of the proposed payment.

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

          Section 3.08.  Cancellation.  Unless otherwise specified pursuant to
Section 3.01 for Debt Securities of any series, all Debt Securities surrendered
for payment, redemption, transfer, exchange or credit against any sinking fund
and all Coupons surrendered for payment or exchange shall, if surrendered to any
Person other than the Trustee, be delivered to the Trustee.  All Registered
Securities and matured Coupons so delivered shall be promptly cancelled by the
Trustee.  All Bearer Securities and unmatured Coupons so delivered shall be held
by the Trustee and, upon instruction by the Company Order, shall be cancelled or
held for reissuance.  Bearer Securities and unmatured Coupons held for
reissuance may be reissued only in exchange for Bearer Securities of the same
series and of like Stated Maturity and with like terms and conditions pursuant
to Section 3.05 or in replacement of mutilated, lost, stolen or destroyed Bearer
Securities of the same series and of like Stated Maturity and with like terms
and conditions or the related Coupons pursuant to Section 3.06.  All Bearer
Securities and unmatured Coupons held by the Trustee pending such cancellation
or reissuance shall be deemed to be delivered for cancellation for all purposes
of this Indenture and the Debt Securities.  The Company may at any time deliver
to the Trustee for cancellation any Debt Securities or Coupons previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and may deliver to the Trustee (or to any other Person for
delivery to the Trustee) for cancellation any Debt Securities previously
authenticated hereunder which the Company has not issued, and all Debt
Securities or Coupons so delivered shall be promptly cancelled by the Trustee.
No Debt Securities or Coupons shall be authenticated in lieu of or in exchange
for any Debt Securities or Coupons cancelled as provided in this Section, except
as expressly permitted by this Indenture.  All cancelled Debt Securities and
Coupons held by the Trustee shall be delivered to the Company upon Company
Request.  The acquisition of any Debt Securities or Coupons by the Company shall
not operate as a redemption or satisfaction of the indebtedness represented
thereby unless and until such Debt Securities or Coupons are surrendered to the
Trustee for cancellation.  In the case of any temporary Global Note which shall
be destroyed if the entire aggregate principal amount of the Debt Securities
represented thereby has been exchanged, the certificate of destruction shall
state that all certificates

                                       32
<PAGE>
 
required pursuant to Section 3.04 hereof and substantially in the form of
Exhibit B hereto, to be given by the Euro-clear Operator or CEDEL, have been
duly presented to the Trustee by the Euro-clear Operator or CEDEL, as the case
may be.  Permanent Global Notes shall not be destroyed until exchanged in full
for definitive Debt Securities or until payment thereon is made in full.

          Section 3.09.  Computation of Interest.  Except as otherwise specified
pursuant to Section 3.01 for Debt Securities of any series, interest on the Debt
Securities of each series shall be computed on the basis of a 360-day year of
twelve 30-day months.

          Section 3.10.  Exchange Upon Default.  If a default occurs in the
payments referred to in Section 12.01, the Company hereby undertakes that upon
presentation and surrender of a permanent Global Note to the Trustee (or to any
other Person or at any other address as the Company may designate in writing),
on any Business Day on or after the maturity date thereof the Company will issue
and the Trustee will authenticate and deliver to the bearer of such permanent
Global Note duly executed and authenticated definitive Debt Securities with the
same issue date and maturity date as set out in such permanent Global Note.

                           SATISFACTION AND DISCHARGE

          Section 4.01.  Satisfaction and Discharge of Indenture.  This
Indenture, with respect to the Debt Securities of any series (if all series
issued under this Indenture are not to be affected), shall upon Company Request,
cease to be of further effect (except as to any surviving rights of registration
of transfer or exchange of such Debt Securities herein expressly provided for
and rights to receive payments of principal (and premium, if any) and interest
on such Debt Securities, and any surviving rights of conversion or exchange of
such Debt Securities if such Debt Securities are convertible or exchangeable)
and the Trustee, at the expense of the Company, shall execute proper instruments
acknowledging satisfaction and discharge of this Indenture, when

               (1) either (A) all Debt Securities and the Coupons, if any, of
          such series theretofore authenticated and delivered (other than (i)
          Debt Securities and Coupons of such series which have been destroyed,
          lost or stolen and which have been replaced or paid as provided in
          Section 3.06, (ii) Coupons appertaining to Bearer Securities
          surrendered for exchange for Registered Securities and maturing after
          such exchange, whose surrender is not required or has been waived
          under Section 3.05, (iii) Coupons

                                       33
<PAGE>
 
          appertaining to Bearer Securities called for redemption and maturing
          after the relevant Redemption Date, whose surrender has been waived as
          provided in Section 13.06, and (iv) Debt Securities and Coupons of
          such series for whose payment money has theretofore been deposited in
          trust or segregated and held in trust by the Company and thereafter
          repaid to the Company or discharged from such trust, as provided in
          Section 12.04) have been delivered to the Trustee for cancellation; or
          (B) all Debt Securities and the Coupons, if any, of such series not
          theretofore delivered to the Trustee for cancellation, (i) have become
          due and payable, or (ii) will become due and payable at their Stated
          Maturity within one year, or (iii) are to be called for redemption
          within one year under arrangements satisfactory to the Trustee for the
          giving of notice by the Trustee in the name, and at the expense, of
          the Company, and the Company, in the case of (i), (ii) or (iii) of
          this subclause (B), has irrevocably deposited or caused to be
          deposited with the Trustee as trust funds in trust for such purpose an
          amount sufficient to pay and discharge the entire indebtedness on such
          Debt Securities for principal (and premium, if any) and interest to
          the date of such deposit (in the case of Debt Securities which have
          become due and payable) or to the Stated Maturity or Redemption Date,
          as the case may be; provided, however, in the event a petition for
          relief under the federal bankruptcy laws, as now or hereafter
          constituted, or any other applicable federal bankruptcy, insolvency or
          other similar law, is filed with respect to the Company within 91 days
          after the deposit and the Trustee is required to return the deposited
          money to the Company, the obligations of the Company under this
          Indenture with respect to such Debt Securities shall not be deemed
          terminated or discharged;

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

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

               (4) the Company has delivered to the Trustee an Opinion of
          Counsel or a ruling by the Internal Revenue Service to the effect that
          Holders of the Debt Securities of the series will not recognize
          income, gain or loss for federal income tax purposes as a result of
          such deposit and discharge.

                                       34
<PAGE>
 
Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.07, the obligations of
the Trustee to any Authenticating Agent under Section 6.14, the obligations of
the Company under Section 12.01, and, if money shall have been deposited with
the Trustee pursuant to subclause (B) of clause (1) of this Section, the
obligations of the Trustee under Section 4.02 and the last paragraph of Section
12.04, shall survive.

          Section 4.02.  Application of Trust Money.  Subject to the provisions
of the last paragraph of Section 12.04, all money deposited with the Trustee
pursuant to Section 4.01 shall be held in trust and applied by it, in accordance
with the provisions of the Debt Securities and Coupons, if any, and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium, if
any) and interest for whose payment such money has been deposited with the
Trustee.

                             DEFAULTS AND REMEDIES

          Section 5.01.  Events of Default.  An "Event of Default" with respect
to the Debt Securities of any series occurs if:

          (1) the Company defaults in any payment of interest on any Debt
     Security or any payment with respect to the Coupons, if any, of such series
     when the same becomes due and payable and such default continues for a
     period of 30 days;

          (2) the Company defaults in the payment of the principal of (and
     premium, if any, on) any Debt Security of such series when the same becomes
     due and payable at its Stated Maturity, upon optional or special
     redemption, upon declaration or otherwise;

          (3) the Company defaults in the deposit of any sinking fund payment,
     when and as due by the terms of a Debt Security or such series;

          (4) the Company defaults in the performance of, or breaches, any
     covenant or warranty on the part of the Company contained in this Indenture
     (other than a covenant or warranty on the part of the Company, a default in
     whose performance or whose breach is specifically addressed elsewhere in
     this Section 5.01 or which expressly has been included herein solely for
     the benefit of Debt Securities of a series other than such series), and
     continuance of such default or breach for a period of 60 days after written

                                       35
<PAGE>
 
     notice thereof, which must specify the default or breach, demand it be
     remedied and state that the notice is a "Notice of Default," has been given
     to the Company by the Trustee or to the Company and the Trustee by the
     Holders of at least 25% in aggregate principal amount (at the time of such
     notice) of Outstanding Debt Securities of such series;

          (5) a default under any mortgage, indenture or instrument under which
     there may be issued, secured or evidenced any indebtedness for money
     borrowed by the Company or any Significant Subsidiary in an aggregate
     principal amount exceeding $25,000,000, which default shall have resulted
     in such indebtedness becoming or being declared due and payable prior to
     the date on which it would otherwise have become due and payable, or with
     respect to which the principal amount remains unpaid upon its stated
     maturity, without such indebtedness having been discharged, or such
     acceleration having been rescinded or annulled, or there having been
     deposited in trust a sum of money sufficient to discharge in full such
     indebtedness, within a period of 30 days after there shall have been given
     to the Company by the Trustee, or to the Company and the Trustee by the
     holders of at least 25% of the aggregate principal amount of Outstanding
     Debt Securities of such series then outstanding, a written notice
     specifying such default and requiring the Company to cause such
     indebtedness to be discharged, to cause there to be deposited in trust a
     sum sufficient to discharge in full such indebtedness or to cause such
     acceleration to be rescinded or annulled and stating that such notice is a
     "Notice of Default";

          (6) the Company or any Significant Subsidiary pursuant to or within
     the meaning of any Bankruptcy Law:

               (A)  commences a voluntary case,

               (B) consents to the entry of an order for relief against it in an
          involuntary case,

               (C) consents to the appointment of a Custodian of it or for all
          or substantially all of its property, or

               (D) makes a general assignment for the benefit of its creditors;
          or

          (7) a court of competent jurisdiction enters an order or decree under
     any Bankruptcy Law that:

               (A) is for relief against the Company or any Significant
          Subsidiary in an involuntary case,

               (B) appoints a Custodian of the Company or any Significant
          Subsidiary or for all or substantially all of its property, or

                                       36
<PAGE>
 
               (C) orders the winding up or liquidation of the Company or any
          Significant Subsidiary,

     and in each case the order or decree remains unstayed and in effect for a
     period of 60 consecutive days.

          (8) the entry by a court having jurisdiction in the premises of one or
     more judgments or orders against the Company or any Significant Subsidiary
     for the payment of money in an aggregate amount in excess of $25,000,000
     (to the extent not covered by insurance) which remain undischarged or
     unsatisfied for a period of 60 consecutive days after the judgments or
     orders become final and the right to appeal them has expired.

          The term "Bankruptcy Law" means Title 11 of the United States Code, or
any similar Federal or state law for the relief of debtors.  The term
"Custodian" means any receiver, trustee, assignee, liquidator, custodian or
similar official under any Bankruptcy Law.

          The Company shall deliver to the Trustee, within 30 days after the
occurrence thereof, written notice, in the form of an Officers' Certificate, of
any event which with the giving of notice and the lapse of time would become an
Event of Default under clauses (5) or (8).  Such notice shall specify the status
of such event and what action the Company is taking or proposes to take with
respect thereto.

          Section 5.02.  Acceleration; Rescission.  If an Event of Default with
respect to Debt Securities of any series at the time Outstanding (other than an
Event of Default specified in Section 5.01(6) or (7)) occurs and is continuing,
then in every case either the Trustee or the Holders of not less than 25% in
aggregate principal amount (at the time of such notice) of Outstanding Debt
Securities of such series may declare the then principal amount (or, if any Debt
Securities of such series are Discount Securities, such portion of the principal
amount of such Discount Securities as may be specified in the terms of such
Discount Securities) and accrued interest, if any, on all the Debt Securities of
such series to be due and payable immediately, by a notice in writing to the
Company (and to the Trustee if given by Holders), and upon any such declaration
such principal amount (or specified amount) shall become immediately due and
payable.  Upon payment of such amount, all obligations of the Company in respect
of the payment of principal of the Debt Securities of such series shall
terminate.  If an Event of Default specified in Section 5.01(6) or (7) with
respect to the Company occurs and is continuing, the principal amount of and
interest on all the Debt Securities then outstanding shall ipso facto become and
be immediately due and payable without any declaration or other act on the part
of the Trustee or any Holder of Debt Securities.

                                       37
<PAGE>
 
          At any time after such a declaration of acceleration with respect to
Debt 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 Debt Securities of such series, by written notice to the Company and
the Trustee, may rescind and annul such declaration and its consequences if

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

          (A)  all overdue installments of interest on all Debt Securities or
               all overdue payments with respect to any Coupons of such series,

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

          (C)  to the extent that payment of such interest is lawful, interest
               upon overdue installments of interest on each Debt Security of
               such series or upon overdue payments on any Coupons of such
               series at the rates prescribed therefor in such Debt 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 Debt Securities of such
series, other than the nonpayment of the principal of Debt Securities of such
series which has become due solely by such declaration of acceleration, have
been cured or waived as provided in Section 5.04.

          Section 5.03.  Other Remedies.  If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal amount of (and premium, if any, on) or interest on the Debt
Securities or to enforce the performance of any provision of the Debt Securities
or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any
of the Debt Securities or does not produce any of them in the proceeding.  A
delay or omission by the Trustee or any Holder of Debt Securities in exercising
any right or remedy accruing upon an Event of Default shall not impair the right
or

                                       38
<PAGE>
 
remedy or constitute a waiver of or acquiescence in the Event of Default.  No
remedy is exclusive of any other remedy.  All available remedies are cumulative.

          Section 5.04.  Waiver of Past Defaults.  Subject to Section 5.07, the
Holders of not less than a majority in aggregate principal amount (at the time
of such notice) of Outstanding Debt Securities of any series by notice to the
Trustee, may on behalf of the Holders of all the Debt Securities of any such
series waive any existing or past Default under this Indenture with respect to
such series and its consequences, except a Default or Event of Default (1) in
the payment of the principal amount of (or premium, if any) or interest on a
Debt Security of such series, or in the payment of any sinking fund installment
or analogous obligation with respect to the Debt Securities of such series, as
specified in clauses (1), (2) and (3) of Section 5.01, or (2) in respect of a
covenant or provision hereof which pursuant to Section 11.02 cannot be modified
or amended without the consent of the Holder of each Outstanding Debt Security
of such series affected.  Upon any such waiver, such Default will cease to
exist, and any Event of Default arising therefrom will be deemed to have been
cured, for every purpose of the Debt Securities of such series under this
Indenture, but no such waiver will extend to any subsequent or other Default or
impair any right consequent thereon.

          Section 5.05.  Control by Majority.  The Holders of a majority in
aggregate principal amount (at the time) of Outstanding Debt Securities of any
series may direct the time, method and place of conducting any proceeding for
any remedy available to the Trustee or exercising any trust or power conferred
on the Trustee with respect to the Debt Securities of such series.  However, the
Trustee may refuse to follow any direction that conflicts with any rule of law
or this Indenture or, subject to Section 6.01, that the Trustee in good faith
determines is unduly prejudicial to the rights of other Holders of Debt
Securities of such series not joining in any such direction or would involve the
Trustee in personal liability; provided, however, that the Trustee may take any
other action deemed proper by the Trustee that is not inconsistent with such
direction.  Prior to taking any action hereunder, the Trustee shall be entitled
to indemnification reasonably satisfactory to it against all losses and expenses
caused by taking or not taking such action.

          Section 5.06.  Limitation on Suits.  No Holder of any Debt Security,
or Coupon of any series, shall have any right to institute any proceeding,
judicial or otherwise, with respect to this Indenture, or for the appointment of
a receiver or trustee, or for any other remedy hereunder unless:

          (1) such Holder has previously given to the Trustee written notice
     stating that an Event of Default is continuing with respect to such series;

                                       39
<PAGE>
 
          (2) the Holders of at least 25% in aggregate principal amount of
     Outstanding Debt Securities of such series shall have made a written
     request to the Trustee to pursue the remedy in respect of such Event of
     Default;

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


          (4) the Trustee does not comply with the request within 60 days after
     receipt of the notice, request and offer of indemnity and such Event of
     Default has not been cured or waived; and

          (5) the Holders of a majority in aggregate principal amount of
     Outstanding Debt Securities of such series have not given the Trustee a
     direction inconsistent with such written request during such 60-day period.

          A Holder of Debt Securities may not use this Indenture to prejudice
the rights of another Holder of Outstanding Debt Securities or Coupons, or to
obtain a preference or priority over any other such Holders, except in the
manner herein provided and for the equal and ratable benefit of all of such
Holders.

          Section 5.07.  Rights of Holders to Receive Payment. Notwithstanding
any other provision of this Indenture, the right of any Holder to receive
payment of principal of (and premium, if any) and interest on the Debt
Securities or Coupons held by such Holder, on or after the respective due dates
expressed in the Debt Securities or Coupons, or to bring suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of such Holder.

          Section 5.08.  Collection Suit by Trustee.  If an Event of Default in
payment of interest or principal (and premium, if any) or the making or
satisfaction of any sinking fund payment or analogous obligation specified in
Section 5.01(1), (2) or (3) occurs and is continuing, the Trustee may recover
judgment in its own name and as trustee of an express trust against the Company
for the whole amount of principal (and premium, if any) and interest remaining
unpaid (together with interest on such unpaid principal (and premium, if any)
and interest at the Overdue Rate, to the extent lawful) and the amounts provided
for in Section 6.07.

          Section 5.09.  Trustee May File Proofs of Claim.  The Trustee may file
such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Holders of Debt
Securities and Coupons allowed in any judicial proceedings relative to the
Company, its creditors or its property and, unless prohibited by law or
applicable regulations, may vote on behalf of the Holders

                                       40
<PAGE>
 
in any election of a trustee in bankruptcy or other Person performing similar
functions, and be entitled and empowered to collect and receive any monies or
other property payable or deliverable on any such claims and to distribute the
same, and any custodian in any such judicial proceeding is hereby authorized by
each Holder to make 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 its counsel, and any
other amounts due the Trustee under Section 6.07.  Nothing herein contained
shall be deemed to authorize or consent to or accept or adopt on behalf of any
Holder of Debt Securities or Coupons any plan of reorganization, arrangement,
adjustment or composition affecting the Debt Securities and any Coupons of such
series 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.

          Section 5.10.  Priorities.  If the Trustee collects any money pursuant
to this Article Five or, if notice of an acceleration under Section 5.02 has
been delivered to the Company and is in effect and the Company has deposited
money with the Trustee, it shall pay out the money in the following order, at
the date or dates fixed by the Trustee and, in case of the distribution of such
money on account of principal (and premium, if any) or interest, upon
presentation of the Debt Securities or Coupons of any series in respect of which
money has been collected and the notation thereon of the payment if only
partially paid and upon surrender thereof if fully paid:

          FIRST:  to the Trustee for amounts due under Section 6.07;

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

          THIRD:  to the Company, its successors and assigns.

          The Trustee may fix a record date and payment date for any payment to

15 days before such record date, the Trustee shall mail to each Holder of Debt
Securities or Coupons and the Company a notice that states the record date, the
payment date and the amount to be paid.

enforcement of any right or remedy under this Indenture or in

                                       41
<PAGE>
 
any suit against the Trustee for any action taken or omitted by it as Trustee, a
court in its discretion may require the filing by any party litigant in the suit
of an undertaking to pay the costs of the suit, and the court in its discretion
may assess reasonable costs, including reasonable attorneys' fees, against any
party litigant in the suit, having due regard to the merits and good faith of
the claims or defenses made by the party litigant.  This Section 5.11 does not
apply to a suit by the Trustee, a suit by a Holder pursuant to Section 5.07 or a
suit by Holders of more than 10% in aggregate principal amount of the
Outstanding Debt Securities of any series.

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 shall not hinder, delay or impede the execution
of any power herein granted to the Trustee, but shall suffer and permit the
execution of every such power as though no such law had been enacted.

          Section 5.13.  Restoration of Rights and Remedies.  If the Trustee or
any Holder has instituted any proceeding to enforce any right or remedy under
this Indenture and such proceeding has been discontinued or abandoned for any
reason, or has been determined adversely to the Trustee or to such Holder, then
and in every such case, subject to any determination in such proceeding, the
Company, the Trustee and the Holders shall be restored severally and
respectively to their former positions hereunder and thereafter all rights and
remedies of the Company, the Trustee and the Holders shall continue as though no
such proceeding had been instituted.


                                  ARTICLE SIX

                                  THE TRUSTEE

          Section 6.01.  Certain Duties and Responsibilities.  (a) Except during
the continuance of an Event of Default with respect to the Debt Securities of
any series,

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

               (2) in the absence of bad faith on its part, the Trustee may
          conclusively rely, as to the truth of the

                                       42
<PAGE>
 
          statements and the correctness of the opinions expressed therein, upon
          certificates or opinions furnished to the Trustee and conforming to
          the requirements of this Indenture; but in the case of any such
          certificates or opinions which by any provisions hereof are
          specifically required to be furnished to the Trustee, the Trustee
          shall be under a duty to examine the same to determine whether or not
          they conform to the requirements of this Indenture.


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

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

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

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

               (3) the Trustee shall not be liable with respect to any action
          taken, suffered or omitted to be taken by it in good faith with
          respect to Debt Securities of any series in accordance with the
          direction of the Holders of a majority in principal amount of the
          Outstanding Debt Securities of such series relating to the time,
          method and place of conducting any proceeding for any remedy available
          to the Trustee, or exercising any trust or power conferred upon the
          Trustee, under this Indenture; and

               (4) the Trustee shall not be required to expend or risk its own
          funds or otherwise incur any financial liability in the performance of
          any of its duties hereunder, or in the exercise of any of its rights
          or powers, if it shall have reasonable grounds for believing that
          repayment of such funds or adequate indemnity against such risk or
          liability is not reasonably assured to it.

          (d) Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or

                                       43
<PAGE>
 
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

          Section 6.02.  Notice of Defaults.  Within 90 days after the
occurrence of any Default hereunder with respect to Debt Securities or Coupons,
if any, of any series, the Trustee shall give notice to all Holders of Debt
Securities and Coupons of such series of such Default hereunder known to the
Trustee, unless such Default shall have been cured or waived; provided, however,
that, except in the case of a Default in the payment of the principal of (or
premium, if any) or interest on any Debt Security or Coupon of such series or in
the payment of any sinking fund installment with respect to Debt Securities of
such series, the Trustee shall be protected in withholding such notice if and so
long as the board of directors, the executive committee or a trust committee of
directors and/or Responsible Officers of the Trustee in good faith determine
that the withholding of such notice is in the interest of the Holders of Debt
Securities and of Coupons of such series; and provided, further, that in the
case of any Default of the character specified in Section 5.01(4) with respect
to Debt Securities of such series no such notice to Holders shall be given until
at least 30 days after the occurrence thereof.

          Notice given pursuant to this Section 6.02 shall be transmitted by
mail:

               (1) to all Registered Holders, as the names and addresses of the
          Registered Holders appear in the Security Register;

               (2) to such Holders of Bearer Securities of any series as have,
          within two years preceding such transmission, filed their names and
          addresses with the Trustee for such series for that purpose; and

               (3) to each Holder of a Debt Security of any series whose name
          and address appears in the information preserved at the time by the
          Trustee in accordance with Section 7.02(a) of this Indenture.

          Section 6.03.  Certain Rights of Trustee.  Except as otherwise
provided in Section 6.01:

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

          (b)  any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a Company Request or

                                       44
<PAGE>
 
Company Order and any resolution of the Board of Directors shall be sufficiently
evidenced by a Board Resolution;

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

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

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

          (f)  the Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document, but the
Trustee, in its discretion, may make such further inquiry or investigation into
such facts or matters as it may see fit, and, if the Trustee shall determine to
make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Company, personally or by agent or attorney;

          (g)  the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder; and

          (h)  in accepting the trust and by performing the duties set forth
under this Indenture, the Trustee is acting solely as trustee hereunder, and not
in its individual capacity, and any Holder having any claim against the Trustee
arising by reason hereof, shall look only to the assets deposited with the
Trustee by the Company for the benefit of the Holders for the payment of
principal of, or interest on, the Debt Securities.  No provision of this
Indenture shall require the Trustee to expend or risk its own funds in the
performance of its duties hereunder.  The Trustee shall have no liability or
responsibility hereunder with respect to moneys except to the extent that such
moneys are actually received by it.  The Trustee shall have no liability or

                                       45
<PAGE>
 
duty to disburse any funds under this Indenture unless such funds under this
Indenture unless such funds are immediately available to the Trustee.

          Section 6.04.  Not Responsible for Recitals or Issuance of Debt
Securities.  The recitals contained herein and in the Debt  Securities, except
the Trustee's certificates of authentication, shall be taken as the statements
of the Company, and the Trustee assumes no responsibility for their correctness.
The Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Debt Securities or Coupons, if any, of any series.  The
Trustee shall not be accountable for the use or application by the Company of
any Debt Securities or the proceeds thereof.

          Section 6.05.  May Hold Debt Securities.  The Trustee, any Paying
Agent, the Security Registrar or any other agent of the Company, in its
individual or any other capacity, may become the owner or pledgee of Debt
Securities or Coupons, and, subject to Sections 6.08 and 6.13, may otherwise
deal with the Company with the same rights it would have if it were not Trustee,
Paying Agent, Security Registrar or such other agent.

          Section 6.06.  Money Held in Trust.  Money held by the Trustee or any
Paying Agent in trust hereunder need not be segregated from other funds except
for funds of the Company and to the extent required by law.  Neither the Trustee
nor any Paying Agent shall be under any liability for interest on any money
received by it hereunder except as otherwise agreed with the Company.

          Section 6.07.  Compensation and Reimbursement.  The Company agrees:

          (1) to pay to the Trustee from time to time reasonable compensation in
     Dollars for all services rendered by it hereunder (which compensation shall
     not be limited by any provision of law in regard to the compensation of a
     trustee of an express trust);

          (2) except as otherwise expressly provided herein, to reimburse the
     trustee in Dollars upon its request for all reasonable expenses,
     disbursements and advances incurred or made by the Trustee in accordance
     with any provision of this Indenture (including the reasonable compensation
     and the expenses and disbursements of its agents and counsel), except any
     such expense, disbursement or advance as may be attributable to its
     negligence or bad faith; and

          (3) to indemnify in Dollars the Trustee for, and to hold it harmless
     against, any loss, liability or expense incurred without negligence or bad
     faith on its part, arising out of or in connection with the acceptance or
     administration of this trust or performance of its duties

                                       46
<PAGE>
 
     hereunder, including the costs and expenses of defending itself against any
     claim or liability in connection with the exercise or performance of any of
     its powers or duties hereunder.

          As security for the performance of the obligations of the Company
under this Section, the Trustee shall have a claim prior to the Debt Securities
and Coupons, if any, upon all property and funds held or collected by the
Trustee as such, except funds held in trust for the payment of amounts due on
the Debt Securities and Coupons.

          The obligations of the Company under this Section 6.07 to compensate
and indemnify the Trustee for expenses, disbursements and advances shall
constitute additional indebtedness under this Indenture and shall survive the
satisfaction and discharge of this Indenture.

          Section 6.08.  Disqualification; Conflicting Interests.  The Trustee
shall comply with Section 310(b) of the TIA.

          Section 6.09.  Corporate Trustee Required; Eligibility.  There shall
at all times be a Trustee hereunder which shall 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 exercise corporate
trust powers, having a combined capital and surplus of at least $75,000,000,
subject to supervision or examination by Federal, State or District of Columbia
authority.  If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of the aforesaid supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published.
Neither the Company nor any Person directly or indirectly controlling,
controlled by, or under common control with the Company shall serve as Trustee
upon any Debt Securities.

          Section 6.10.  Resignation and Removal; Appointment of Successor.  (a)
No resignation or removal of the Trustee and no appointment of a successor
Trustee pursuant to this Article shall become effective until the acceptance of
appointment by the successor Trustee under Section 6.11.

          (b)  The Trustee may resign at any time with respect to the Debt
Securities of one or more series by giving written notice thereof to the
Company.  If an instrument of acceptance by a successor Trustee shall not have
been delivered to the Trustee within 60 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the Debt
Securities of such series.

                                       47
<PAGE>
 
          (c)  The Trustee may be removed at any time with respect to the Debt
Securities of any series and a successor Trustee appointed by Act of the Holders
of a majority in principal amount of the Outstanding Debt Securities of such
series, delivered to the Trustee and to the Company.

          (d)  If at any time:

               (1)  the Trustee shall fail to comply with Section 6.08(a) with
          respect to the Debt Securities of any series after written request
          therefor by the Company or by any Holder who has been a bona fide
          Holder of a Debt Security of such series for at least six months, or

               (2)  the Trustee shall cease to be eligible under Section 6.09
          with respect to the Debt Securities of any series and shall fail to
          resign after written request therefor by the Company or by any such
          Holder, or

               (3)  the Trustee shall become incapable of acting or shall be
          adjudged a bankrupt or insolvent or a receiver of the Trustee or of
          its property shall be appointed or any public officer shall take
          charge or control of the Trustee or of its property or affairs for the
          purpose of rehabilitation, conservation or liquidation, then, in any
          such case, (i) the Company by a Board Resolution may remove the
          Trustee with respect to all Debt Securities, or (ii) subject to
          Section 5.11, any Holder who has been a bona fide Holder of a Debt
          Security of any series for at least six months may, on behalf of
          himself and all others similarly situated, petition any court of
          competent jurisdiction for the removal of the Trustee and the
          appointment of a successor Trustee for the Debt Securities of such
          series.

          (e)  If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Debt Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Debt Securities of that or those series (it being understood that any
such successor Trustee may be appointed with respect to the Debt 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 Debt 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 Debt Securities of any series
shall be appointed by Act of the Holders of a majority in principal amount of
the Outstanding Debt 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, become the

                                       48
<PAGE>
 
successor Trustee with respect to the Debt Securities of such series and to that
extent supersede the successor Trustee appointed by the Company.  If no
successor Trustee with respect to the Debt Securities of any series shall have
been so appointed by the Company or the Holders of such series and accepted
appointment in the manner hereinafter provided, any Holder who has been a bona
fide Holder of a Debt Security of such series for at least six months may,
subject to Section 5.11, 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 Debt Securities of such series.

          (f)  The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Debt Securities of any series and
each appointment of a successor Trustee with respect to the Debt Securities of
any series in the manner and to the extent provided in Section 16.03 to the
Holders of Debt Securities of such series.  Each notice shall include the name
of the successor Trustee with respect to the Debt Securities of such series and
the address of its Corporate Trust Office.

          Section 6.11.  Acceptance of Appointment by Successor.  (a) In the
case of an appointment hereunder of a successor Trustee with respect to all Debt
Securities, each such successor Trustee so appointed shall execute, acknowledge
and deliver to the Company and to 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 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, subject nevertheless to its claim, if any,
provided for in Section 6.07.

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

                                       49
<PAGE>
 
retiring Trustee with respect to the Debt 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 any 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 other trust
or trusts hereunder administered by any other such Trustee; and upon the
execution and delivery of any 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 Debt 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
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 with respect to the Debt Securities of that or
those series to which the appointment of such successor Trustee relates, subject
nevertheless to its claim, if any, provided for in Section 6.07.

          (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) or (b) of this Section, as the case may be.

          (d)  No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee 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 of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided that 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 Debt 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 Debt Securities so authenticated
with the same effect as if such successor Trustee had itself authenticated such
Debt

                                       50
<PAGE>
 
Securities. In case any Debt Securities shall not have been authenticated by
such predecessor Trustee, any such successor Trustee may authenticate and
deliver such Debt Securities, in either its own name or that of its predecessor
Trustee, with the full force and effect which this Indenture provides for the
certificate of authentication of the Trustee.

          Section 6.13.  Preferential Collection of Claims Against Company.  The
Trustee shall comply with Section 311(a) of the TIA, excluding any creditor
relationship listed in Section 311(b) of the TIA.  A Trustee who has resigned or
been removed shall be subject to Section 311(a) of the TIA to the extent
indicated therein.

          Section 6.14.  Appointment of Authenticating Agent.  As long as any
Debt Securities of a series remain Outstanding, upon a Company Request, there
shall be an authenticating agent (the "Authenticating Agent") appointed, for
such period as the Company shall elect, by the Trustee for such series of Debt
Securities to act as its agent on its behalf and subject to its direction in
connection with the authentication and delivery of each series of Debt
Securities for which it is serving as Trustee.  Debt Securities of each such
series authenticated by such Authenticating Agent shall be entitled to the
benefits of this Indenture and shall be valid and obligatory for all purposes as
if authenticated by such Trustee.  Wherever reference is made in this Indenture
to the authentication and delivery of Debt Securities of any series by the
Trustee for such series or to the Trustee's Certificate of Authentication, such
reference shall be deemed to include authentication and delivery on behalf of
the Trustee for such series by an Authenticating Agent for such series and a
Certificate of Authentication executed on behalf of such Trustee by such
Authenticating Agent, except that only the Trustee may authenticate Debt
Securities upon original issuance and pursuant to Section 3.06 hereof.  Such
Authenticating Agent shall at all times be a corporation organized and doing
business under the laws of the United States of America or of any State,
authorized under such laws to exercise corporate trust powers, having a combined
capital and surplus of at least $10,000,000 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 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 any Authenticating Agent may be merged or
converted, or with which it may be consolidated, or any corporation resulting
from any merger, conversion or

                                       51

consolidation to which any Authenticating Agent shall be a party, or any
corporation succeeding to the corporate agency business of any Authenticating
Agent, shall continue to be the Authenticating Agent with respect to all series
of Debt Securities for which it served as Authenticating Agent without the
execution or filing of any paper or any further act on the part of the Trustee
for such series or such Authenticating Agent.  Any Authenticating Agent may at
any time, and if it shall cease to be eligible shall, resign by giving written
notice of resignation to the applicable Trustee and to the Company.

          Upon receiving such a notice of resignation or upon such a
termination, or in case at any time any Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section 6.14 with respect to
one or more or all series of Debt Securities, the Trustee for such series shall
upon Company Request appoint a successor Authenticating Agent, and the Company
shall provide notice of such appointment to all Holders of Debt Securities of
such series in the manner and to the extent provided in Section 16.03.  Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all rights, powers, duties and responsibilities of its
predecessor hereunder, with like effect as if originally named as Authenticating
Agent herein.  The Trustee for the Debt Securities of such series agrees to pay
to the Authenticating Agent for such series from time to time reasonable
compensation for its services, and the Trustee shall be entitled to be
reimbursed for such payment, subject to the provisions of Section 6.07.  The
Authenticating Agent for the Debt Securities of any series shall have no
responsibility or liability for any action taken by it as such at the direction
of the Trustee for such series.

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

          This is one of the series of Debt Securities issued under the within
mentioned Indenture.

               HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

          Section 7.01.  Company to Furnish Trustee Names and Addresses of
Holders.  The Company will furnish or cause to be furnished to the Trustee with
respect to Registered Securities of each series for which it acts as Trustee:

          (a) semi-annually on a date not more than 15 days after each Regular
Record Date with respect to an Interest Payment Date, if any, for the Registered
Securities of such series (or on semi-annual dates in each year to be determined
pursuant to Section 3.01 if the Registered Securities of such series do not bear
interest), a list, in such form as the Trustee may reasonably require, of the
names and addresses of the Registered Holders as of the date 15 days next
preceding each such Regular Record Date (or such semi-annual dates, as the case
may be); and

          (b) at such other times as the Trustee may request in writing, within
30 days after the receipt by the Company of any such request, a list of similar
form and content as of a date not more than 15 days prior to the time such list
is furnished; provided, however, that if and so long as the Trustee shall be the
Security Registrar for such series, no such list need be furnished.

          The Company shall also be required to furnish to the Trustee at all
such times set forth above all information in the possession or control of the
Company or any of its Paying Agents other than the Trustee as to the names and
addresses of the Holders of Bearer Securities of all series; provided, however,
that the Company shall have no obligation to investigate any matter relating to
any Holders of Bearer Securities of any series.

          Section 7.02.  Preservation of Information; Communication to Holders.
(a)  The Trustee shall preserve, in as current a form as is reasonably
practicable, all information as to the names and addresses of Holders contained
in the most recent list furnished to the Trustee as provided in Section 7.01 or
received by it in the capacity of Paying Agent (if so acting) hereunder, and
filed with it within the two preceding years pursuant to Section 7.03(c)(2).

          The Trustee may destroy any list furnished to it as provided in
Section 7.01 upon receipt of a new list so furnished, destroy any information
received by it as Paying Agent (if so acting) hereunder upon delivering to
itself as Trustee, not earlier than 45 days after an Interest Payment Date, a
list containing the names and addresses of the Holders obtained from such
information since the delivery of the next previous list, if any, destroy any
list delivered to itself as Trustee which was

                                       53
<PAGE>
 
compiled from information received by it as Paying Agent (if so acting)
hereunder upon the receipt of a new list so delivered, and destroy not earlier
than two years after filing, any information filed with it pursuant to Section
7.03(c)(2).

          (b) If three or more Holders (hereinafter referred to as "applicants")
apply in writing to the Trustee, and furnish to the Trustee reasonable proof
that each such applicant has owned a Debt Security for a period of at least six
months preceding the date of such application, and such application states that
the applicants desire to communicate with other Holders of Debt Securities of a
particular series (in which case the applicants must hold Debt Securities of
such series) or with all Holders of Debt Securities with respect to their rights
under this Indenture or under the Debt Securities and is accompanied by a copy
of the form of proxy or other communication which such applicants propose to
transmit, then the Trustee shall, within five Business Days after the receipt of
such application, at its election, either

               (i) afford such applicants access to the information preserved at
          the time by the Trustee in accordance with Section 7.02(a), or

               (ii) inform such applicants as to the approximate number of
          Holders of Debt Securities of such series or of all Debt Securities,
          as the case may be, whose names and addresses appear in the
          information preserved at the time by the Trustee in accordance with
          Section 7.02(a), and as to the approximate cost of mailing to such
          Holders the form of proxy or other communication specified in such
          application.

          If the Trustee shall elect not to afford such applicants access to
such information, the Trustee shall, upon written request of such applicants,
mail to the Holders of Debt Securities of such series or all Holders, as the
case may be, whose names and addresses appear in the information preserved at
the time by the Trustee in accordance with Section 7.02(a), a copy of the form
of proxy or other communication which is specified in such request, with
reasonable promptness after a tender to the Trustee of the material to be mailed
and of payment, or provision for the payment, of the reasonable expenses of
mailing, unless within five days after such tender, the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interests of the Holders
of Debt Securities of such series or all Holders, as the case may be, or would
be in violation of applicable law.  Such written statement shall specify the
basis of such opinion.  After opportunity for a hearing upon the objections
specified in the written statement so filed, the Commission may, and if demanded
by the Trustee or by such applicants shall, enter an

                                       54
<PAGE>
 
order either sustaining one or more of such objections or refusing to sustain
any of them.  If the Commission shall enter an order refusing to sustain any of
such objections or if after the entry of an order sustaining one or more of such
objections, the Commission shall find, after notice and opportunity for hearing,
that all the objections so sustained have been met and shall enter an order so
declaring, the Trustee shall mail copies of such material to all such Holders
with reasonable promptness after the entry of such order and the renewal of such
tender; otherwise the Trustee shall be relieved of any obligation or duty to
such applicants respecting their application.

          (c) Every Holder of Debt Securities, by receiving and holding the
same, agrees with the Company and the Trustee that neither the Company nor the
Trustee shall be held accountable by reason of the disclosure of any such
information as to the names and addresses of the Holders in accordance with
Section 7.02(b), regardless of the source from which such information was
derived, and that the Trustee shall not be held accountable by reason of mailing
of any material pursuant to a request made under Section 7.02(b).

          Section  7.03.  Reports by Trustee.  (a)  Within 60 days after May 15
of each year, commencing May 15, 1996, the Trustee shall, to the extent required
by the Trust Indenture Act, transmit to all Holders of Debt Securities of any
series with respect to which it acts as Trustee, in the manner hereinafter
provided in this Section 7.03, a brief report dated such date with respect to
any of the following events which may have occurred within the previous 12
months (but if no such event has occurred within such period no report need be
transmitted):

               (1) any change to its eligibility under Section 6.09 and its
          qualifications under Section 6.08;

               (2) the creation of or any material change to a relationship
          specified in paragraphs (1) through (10) of Section 6.08(c) of this
          Indenture;

               (3) the character and amount of any advances (and if the Trustee
          elects so to state, the circumstances surrounding the making thereof)
          made by the Trustee (as such) which remain unpaid on the date of such
          report, and for the reimbursement of which it claims or may claim a
          lien or charge, prior to that of the Debt Securities of such series,
          on any property or funds held or collected by it as Trustee, except
          that the Trustee shall not be required (but may elect) to report such
          advances if such advances so remaining unpaid aggregate not more than
          1/2 of 1% of the principal amount of the Outstanding Debt Securities
          of such series on the date of such report;

                                       55
<PAGE>
 
               (4) any change to the amount, interest rate and maturity date of
          all other indebtedness owing by the Company (or any other obligor on
          the Debt Securities of such series) to the Trustee in its individual
          capacity, on the date of such report, with a brief description of any
          property held as collateral security therefor, except an indebtedness
          based upon a creditor relationship arising in any manner described in
          Section 6.13(b)(2), (3), (4) or (6);


               (5) any change to the property and funds, if any, physically in
          the possession of the Trustee as such on the date of such report;

               (6) any additional issue of Debt Securities which the Trustee has
          not previously reported; and

               (7) any action taken by the Trustee in the performance of its
          duties hereunder which it has not previously reported and which in its
          opinion materially affects the Debt Securities of such series, except
          action in respect of a Default, notice of which has been or is to be
          withheld by the Trustee in accordance with Section 6.02.

          (b) The Trustee shall transmit by mail to all Holders of Debt
Securities of any series (whose names and addresses appear in the information
preserved at the time by the Trustee in accordance with Section 7.02(a)) for
which it acts as the Trustee, as hereinafter provided, a brief report with
respect to the character and amount of any advances (and if the Trustee elects
so to state, the circumstances surrounding the making thereof) made by the
Trustee (as such) since the date of the last report transmitted pursuant to
subsection (a) of this Section (or if no such report has yet been so
transmitted, since the date of execution of this instrument) for the
reimbursement of which it claims or may claim a lien or charge, prior to that of
the Debt Securities of such series, on property or funds held or collected by it
as Trustee, and which it has not previously reported pursuant to this
subsection, except that the Trustee for each series shall not be required (but
may elect) to report such advances if such advances remaining unpaid at any time
aggregate 10% or less of the principal amount of the Debt Securities of such
series Outstanding at such time, such report to be transmitted within 90 days
after such time.

          (c) Reports pursuant to this Section 7.03 shall be transmitted by
mail:

               (1) to all Holders of Registered Securities, as the names and
          addresses of such Holders of Registered Securities appear in the
          Security Register;

                                       56
<PAGE>
 
               (2) to such Holders of Bearer Securities of any series as have,
          within two years preceding such transmission, filed their names and
          addresses with the Trustee for such series for that purpose; and

               (3) except in the cases of reports pursuant to subsection (b) of
          this Section 7.03, to each Holder of a Debt Security of any series
          whose name and address appears in the information preserved at the
          time by the Trustee in accordance with Section 7.02(a).


          (d) A copy of each such report shall, at the time of such transmission
to Holders, be filed by the Trustee with each stock exchange upon which any Debt
Securities of such series are listed, with the Commission and also with the
Company.  The Company will notify the Trustee when any series of Debt Securities
are listed on any stock exchange.

          Section 7.04.  Reports by Company.  The Company will:

          (1) file with the Trustee, within 15 days after the Company is
required to file the same with the Commission, copies of the annual reports and
of the information, documents and other reports (or copies of such portions of
any of the foregoing as the Commission may from time to time by rules and
regulations prescribe) which the Company may be required to file with the
Commission pursuant to Section 13 or Section 15(d) of the Securities Exchange
Act of 1934, as amended; or, if the Company is not required to file information,
documents or reports pursuant to either of said Sections, then it will file with
the Trustee and the Commission, in accordance with rules and regulations
prescribed from time to time by the Commission, such of the supplementary and
periodic information, documents and reports which may be required pursuant to
Section 13 of the Securities Exchange Act of 1934, as amended, in respect of a
security listed and registered on a national securities exchange as may be
required from time to time in such rules and regulations;

          (2) file with the Trustee and the Commission, in accordance with rules
and regulations prescribed from time to time by the Commission, such additional

with the conditions and covenants of this Indenture as may be required from time

          (3) transmit to all Holders of Debt Securities, in the manner and to
the extent provided in Section 7.03(c), within 30 days after the filing thereof
with the Trustee, such summaries of any information, documents and reports
required to be filed by the Company pursuant to paragraphs (1) and (2) of this
Section as may be required by rules and regulations prescribed from time to time

                             CONCERNING THE HOLDERS

          Section 8.01.  Acts of Holders.  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 or proxy 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.  Whenever in this
Indenture it is provided that the Holders of a specified percentage in aggregate
principal amount of Outstanding Debt Securities of any series may take any Act,
the fact that the Holders of such specified percentage have joined therein may
be evidenced (a) by the instrument or instruments executed by Holders in person
or by agent or proxy appointed in writing, or (b) by the record of Holders
voting in favor thereof at any meeting of such Holders duly called and held in
accordance with the provisions of Article Nine, or (c) by a combination of such
instrument or instruments and any such record of such a meeting of Holders.

          Section 8.02.  Proof of Ownership; Proof of Execution of Instruments
by Holder.  The ownership of Registered Securities of any series shall be proved
by the Security Register for such series or by a certificate of the Security
Registrar for such series.

          The ownership of Bearer Securities shall be proved by production of
such Bearer Securities or by a certificate executed by any bank or trust
company, which certificate shall be dated and shall state that on the date
thereof a Bearer Security bearing a specified identifying number or other mark
was deposited with or exhibited to the Person executing such certificate by the
Person named in such certificate, or by any other proof of possession reasonably
satisfactory to the Trustee.  The holding by the Person named in any such
certificate of any Bearer Security specified therein shall be presumed to
continue for a period of one year unless at the time of determination of such
holding (1) another certificate bearing a later date issued in respect of the
same Bearer Security shall be produced, (2) such Bearer Security shall be
produced by some other Person, (3) such Bearer Security shall have been
registered on the Security Register, if, pursuant to Section 3.01, such Bearer
Security can be so registered, or (4) such Bearer Security shall have been
cancelled or paid.

                                       58
<PAGE>
 
          Subject to the provisions of Sections 6.01, 6.03 and 9.05, proof of
the execution of a writing appointing an agent or proxy and of the execution of
any instrument by a Holder or his agent or proxy shall be sufficient and
conclusive in favor of the Trustee and the Company if made in the following
manner:

          The fact and date of the execution by any such Person of any
instrument may be proved by the certificate of any notary public or other
officer authorized to take acknowledgements of deeds, that the Person executing
such instrument acknowledged to him the execution thereof, or by an affidavit of
a witness to such execution sworn to before any such notary or other such
officer.  Where such execution is by an officer of a corporation or association
or a member of a partnership on behalf of such corporation, association or
partnership, as the case may be, or by any other Person acting in a
representative capacity, such certificate or affidavit shall also constitute
sufficient proof of his authority.

          The record of any Holders' meeting shall be proved in the manner
provided in Section 9.06.

          The Trustee may in any instance require further proof with respect to
any of the matters referred to in this Section so long as the request is a
reasonable one.

          Section 8.03.  Persons Deemed Owners.  The Company, the Trustee and
any agent of the Company or the Trustee may treat the Person in whose name any
Registered Security is registered as the owner of such Registered Security for
the purpose of receiving payment of the principal of (and premium, if any) and
(subject to Section 3.07) interest, if any, on such Registered Security and for
all other purposes whatsoever, whether or not such Registered Security is
overdue, and neither the Company, the Trustee nor any agent of the Company or
the Trustee shall be affected by notice to the contrary.  The Company, the
Trustee, and any agent of the Company or the Trustee may treat the Holder of any
Bearer Security or of any Coupon as the absolute owner of such Bearer Security
or Coupon for the purposes of receiving payment thereof or on account thereof
and for all other purposes whatsoever, whether or not such Bearer Security or
Coupon is overdue, and neither the Company, the Trustee nor any agent of the
Company or the Trustee shall be affected by notice to the contrary.  All
payments made to any Holder, or upon his or her order, shall be valid, and, to
the extent of the sum or sums paid, effectual to satisfy and discharge the
liability for moneys payable upon such Debt Security or Coupon.

          Section 8.04.  Revocation of Consents; Future Holders Bound.  At any
time prior to (but not after) the evidencing to the Trustee, as provided in
Section 8.01, of the taking of any Act by the Holders of the percentage in
aggregate principal amount of the Outstanding Debt Securities specified in this
Indenture in connection with such Act, any Holder of a Debt

                                       59
<PAGE>
 
Security, the number, letter or other distinguishing symbol of which is shown by
the evidence to be included in the Debt Securities the Holders of which have
consented to such Act, may, by filing written notice with the Trustee at the
Corporate Trust Office and upon proof of ownership as provided in Section 8.02,
revoke such Act so far as it concerns such Debt Security.  Except as aforesaid,
any such Act taken by the Holder of any Debt Security shall be conclusive and
binding upon such Holder and, subject to the provisions of Section 5.07, upon
all future Holders of such Debt Security and all past, present and future
Holders of Coupons, if any, appertaining thereto and of any Debt Securities and
Coupons issued on transfer or in lieu thereof or in exchange or substitution
therefor, irrespective of whether or not any notation in regard thereto is made
upon such Debt Security or Coupons or such other Debt Securities or Coupons.


                                  ARTICLE NINE

                               HOLDERS' MEETINGS

all series of Debt Securities may be called at any time and from time to time

purposes:

          (1) to give any notice to the Company or to the Trustee for such
     series, or to give any directions to the Trustee for such series, or to
     consent to the waiving of any Default hereunder and its consequences, or to
     take any other action authorized to be taken by Holders pursuant to any of
     the provisions of Article Five;

          (2) to remove the Trustee for such series and appoint a successor
     Trustee pursuant to the provisions of Article Six;

          (3) to consent to the execution of an indenture or indentures
     supplemental hereto pursuant to the provisions of Section 11.02; or

     the Holders of any specified aggregate principal amount of the Outstanding
     Debt Securities of any one or more or all series, as the case may be, under
     any other provision of this Indenture or under applicable law.

          Section 9.02.  Call of Meetings by Trustee.  The Trustee for any
series may at any time call a meeting of Holders of such series to take any
action specified in Section 9.01, to be held at such time or times and at such
place or places as the Trustee for such series shall determine.  Notice of every
meeting of the Holders of any series, setting forth the time and the place of
such meeting and in general terms the action proposed to

                                       60
<PAGE>
 
be taken at such meeting, shall be given to Holders of such series in the manner

of all series, as the case may be, shall have requested the Trustee for such
series to call a meeting of Holders of any or all such series by written request
setting forth in reasonable detail the action proposed to be taken at the
meeting, and the Trustee shall not have given the notice of such meeting within
20 days after the receipt of such request, then the Company or such Holders may
determine the time or times and the place or places for such meetings and may
call such meetings to take any action authorized in Section 9.01, by giving
notice thereof as provided in Section 9.02.

          Section 9.04.  Qualifications for Voting.  To be entitled to vote at
any meeting of Holders, a Person shall be (a) a Holder of a Debt Security of the

its counsel.

this Indenture, the Trustee for any series may make such reasonable regulations
as it may deem advisable for any meeting of Holders of such series, in regard to

proxies, and in regard to the appointment and duties of inspectors of votes, the
submission and examination of proxies, certificates and other evidence of the
right to vote, and such other matters concerning the conduct of the meeting as
it shall deem appropriate.

          The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders of such series as provided in Section 9.03, in which case
the Company or the Holders calling the meeting, as the case may be, shall in
like manner appoint a temporary chairman.  A permanent chairman and a permanent
secretary of the meeting shall be elected by a majority vote of the meeting.

          Subject to the provisos in the definition of "Outstanding," at any
meeting each Holder of a Debt Security of the series with respect to which such
meeting is being held or

proxy therefor shall be entitled to one vote for each $1,000 principal amount
(or such other amount as shall be specified as contemplated by Section 3.01) of
Debt Securities of such series held or represented by him; provided, however,
that no vote shall be cast or counted at any meeting in respect of any Debt
Security challenged as not Outstanding and ruled by the chairman of the meeting
to be not Outstanding.  The chairman of the meeting shall have no right to vote
other than by virtue of Outstanding Debt Securities of such series held by him

meeting of Holders with respect to which such meeting is being held shall be by
written ballots on which shall be subscribed the signatures of such Holders or
of their representatives by proxy and the serial number or numbers of the Debt

shall appoint two inspectors of votes who shall count all votes cast at the
meeting for or against any resolution and who shall make and file with the
secretary of the meeting their verified written reports in duplicate of all
votes cast at the meeting.  A record in duplicate of the proceedings of each
meeting of Holders shall be taken and there shall be attached to said record the
original reports of the inspectors of votes on any vote by ballot taken thereat
and affidavits by one or more persons having knowledge of the facts setting
forth a copy of the notice of the meeting and showing that said notice was
transmitted as provided in Section 9.02.  The record shall show the serial
numbers of the Debt Securities voting in favor of or against any resolution.
The record shall be signed and verified by the affidavits of the permanent
chairman and secretary of the meeting and one of the duplicates shall be
delivered to the Company and the other to the Trustee to be preserved by the
Trustee.

          Any record so signed and verified shall be conclusive evidence of the
matters therein stated.

          Section 9.07.  No Delay of Rights by Meeting.  Nothing contained in
this Article Nine shall be deemed or construed to authorize or permit, by reason
of any call of a meeting of Holders or any rights expressly or impliedly
conferred hereunder to make such call, any hindrance or delay in the exercise of
any right or rights conferred upon or reserved to the Trustee or to any Holder
under any of the provisions of this Indenture or of the Debt Securities of any
series.

          Section  10.01.  When Company May Merge or Transfer Assets.  The
Company shall not consolidate with or merge into any other Person or convey,
transfer or lease all or substantially all its assets to any Person, unless:

               (i) the Person formed by such consolidation or into which the
          Company is merged or the Person which acquires by conveyance or
          transfer, or which leases, all or substantially all the assets of the
          Company (the "successor corporation") shall be a Person organized and
          existing under the laws of the United States or any State or the
          District of Columbia and shall expressly assume, by an indenture
          supplemental hereto, executed and delivered to the Trustee, in form
          satisfactory to the Trustee, all of the obligations of the Company
          under the Debt Securities and this Indenture; and

               (ii) immediately after giving effect to such transaction, no
          Event of Default, and no event which, after notice or lapse of time,
          or both, would become an Event of Default, shall have happened and be
          continuing.

          The Trustee may request, in accordance with Section 6.03 hereof, an
Officers' Certificate and an Opinion of Counsel each stating that such
consolidation, merger, conveyance, transfer or lease and such supplemental
indenture comply with this Article and that all conditions precedent herein
provided for relating to such transaction have been complied with.

          Upon any consolidation with or merger into any other Person, or any
conveyance, transfer or lease of the properties and assets of the Company
substantially as an entirety in accordance with this Section 10.01, the
successor corporation formed by such consolidation or into which the Company is
merged or to which such conveyance, transfer or lease is made shall succeed to,
and be substituted for, and may exercise every right and power of, the Company
under this Indenture with the same effect as if such successor corporation had
been named as the Company herein, and thereafter the predecessor corporation
shall be relieved of all obligations and covenants under this Indenture and the
Debt Securities.

          (2) to add to the covenants of the Company, for the benefit of the
     Holders of all or any series of Debt Securities and the Coupons, if any,
     appertaining thereto (and if such covenants are to be for the benefit of

     included solely for the benefit of such series), or to surrender any right
     or power herein conferred upon the Company; or

          (3) to add any additional Events of Default (and if such Events of

     and with or without Coupons, to permit Bearer Securities to be issued in
     exchange for Registered Securities, to permit Bearer Securities to be
     issued in exchange for Bearer Securities of other authorized denominations
     or to permit the issuance of Debt Securities of any series in
     uncertificated form, provided that any such action shall not materially
     adversely affect the interests of the Holders of Debt Securities of any
     series or any related Coupons in any material respect; or

          (5) to change or eliminate any of the provisions of this Indenture,
     provided that any such change or elimination shall become effective only
     when there is no Outstanding Debt Security or Coupon of any series created

     the benefit of such provision and as to which such supplemental indenture
     would apply; or

          (6) to secure, or in the case of secured Debt Securities to further
     secure, the Debt Securities; or

          (7) to supplement any of the provisions of this Indenture to such
     extent as shall be necessary to permit or facilitate the defeasance and
     discharge of any series of Securities pursuant to Article Four or Fifteen,
     provided that any such action shall not materially adversely affect the
     interests of the Holders of Debt Securities of such series or any other
     series of Debt Securities or any related Coupons in any material respect;
     or

          (8) to establish the form or terms of Debt Securities and Coupons, if

          (9) to evidence and provide for the acceptance of appointment
     hereunder by a successor Trustee with respect to one or more series of Debt
     Securities and to 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, pursuant to the requirements
     of Section 6.11; or

          (10) to cure any ambiguity, to correct or supplement any provision
     herein which may be defective or inconsistent with any other provision
     herein, or to make any other provisions with respect to matters or
     questions arising under this Indenture which shall not be inconsistent with
     any provision of this Indenture, or to make any other change; provided such
     other provisions or changes shall not adversely affect the interests of the
     Holders of Outstanding Debt Securities or Coupons, if any, of any series
     created prior to the execution of such supplemental indenture in any
     material respect.

          Section 11.02.  Supplemental Indentures With Consent of Holders.  With
the consent of the Holders of not less than a majority in principal amount of
the Outstanding Debt Securities of each series affected by such supplemental
indenture voting separately, by Act of said Holders delivered to the Company and

may enter into an indenture or indentures supplemental hereto for the purpose of
adding provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of modifying in any manner the rights of the
Holders under this Indenture of such Debt Securities; provided, however, that no
such supplemental indenture shall, without the consent of the Holder of each
Outstanding Debt Security of each such series affected thereby,

          (1) change the Stated Maturity of the principal of, or installment of
     interest, if any, on, any Debt Security, or reduce the principal amount
     thereof or the interest thereon or any premium payable upon redemption
     thereof, or change the Stated Maturity of or reduce the amount of any
     payment to be made with respect to any Coupon, or reduce the amount

<PAGE>
 
     of the principal of a Discount Security that would be due and payable upon
     a declaration of acceleration of the Maturity thereof pursuant to Section
     5.02, or adversely affect the right of repayment or repurchase, if any, at
     the option of the Holder, or reduce the amount of, or postpone the date
     fixed for, any payment under any sinking fund or analogous provisions for
     any Debt Security, or limit the obligation of the Company to maintain a

     Defaults hereunder and their consequences provided for in this Indenture.

other provision of this Indenture with respect to one or more particular series
of Debt Securities and Coupons, if any, or which modifies the rights of the

covenant or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Debt securities and Coupons, if any, of any other
series.

          Section 11.03.  Execution of Supplemental Indentures.  In executing,
or accepting the additional trusts created by any supplemental indenture
permitted by this Article or the modifications thereby of the trusts created by
this Indenture, the Trustee shall be entitled to receive, and (subject to

stating that the execution of such supplemental indenture is authorized or
permitted by this Indenture.  The Trustee may, but shall not be obligated to,
enter into any such supplemental indenture which adversely affects the Trustee's
own rights, duties or immunities under this Indenture or otherwise in a material
way.

          Section 11.04.  Effect of Supplemental Indentures.  Upon the execution
of any supplemental indenture under this Article, this Indenture shall be

and delivered after the execution of any supplemental indenture pursuant to this
Article may, and shall if required by the Trustee, bear a notation in form

indenture.  If the Company shall so determine, new Debt Securities and Coupons
of any series so modified as to conform, in the opinion of the Trustee and the
Board of Directors, to any such supplemental indenture may be prepared and
executed by the Company and authenticated and delivered by the Trustee in
exchange for Outstanding Debt Securities and Coupons of such series.

          Section 11.07.  Notice of Supplemental Indenture.  Promptly after the
execution by the Company and the appropriate Trustee of any supplemental
indenture pursuant to Section 11.02, the Company shall transmit, in the manner

          Section 12.01.  Payment of Principal, Premium and Interest.  The
Company covenants and agrees for the benefit of each series of Debt Securities
and Coupons, if any, that it will duly and punctually pay the principal of (and
premium, if any) and interest on the Debt Securities in accordance with the
terms of the Debt Securities, the Coupons and this Indenture.  Unless otherwise
specified as contemplated by Section 3.01 with respect to any series of Debt
Securities or except as otherwise provided in Section 3.06, any interest due on
Bearer Securities on or before Maturity shall be payable only upon presentation
and surrender of the several Coupons for such interest installments as are
evidenced thereby as they severally mature.  If so provided in the terms of any
series of Debt Securities established as provided in Section 3.01, the interest,
if any, due in respect of any temporary Global Note or permanent Global Note,
together with any additional amounts payable in respect thereof, as provided in
the terms and conditions of such Debt Security, shall be payable only upon

          Section 12.02.  Officer's Certificate as to Default.  The Company will
deliver to the Trustee, on or before a date not more than four months after the
end of each fiscal year of the Company (which on the date hereof is the calendar
year) ending after the date hereof, a certificate of the principal executive
officer, principal financial officer or principal accounting officer of the
Company stating whether or not to the knowledge of the signer thereof the
Company is in compliance with all covenants and conditions under this Indenture,
and, if the Company shall be in Default, specifying all such Defaults and the
nature thereof of which such signer may have knowledge.  For purposes of this
Section, such compliance shall be determined without regard to any period of
grace or requirement of notice provided under this Indenture.

          Section 12.03.  Maintenance of Office or Agency.  If  Debt Securities
of a series are issuable only as Registered Securities, the Company will
maintain in each Place of Payment for such series an office or agency where Debt
Securities of that series may be presented or surrendered for payment, where
Debt Securities of that series may be surrendered for registration of transfer
or exchange and where notices and demands to or upon the Company in respect of
the Debt Securities of that series and this Indenture may be served.  If Debt
Securities of a series are issuable as Bearer Securities, the Company will
maintain (A) in the Borough of Manhattan, the City and State of New York, an
office or agency where any Registered Securities of that series may be presented
or surrendered for payment, where any Registered Securities of that series may
be surrendered for registration of transfer, where Debt Securities of that
series may be surrendered for exchange, where notices and demands to or upon the
Company in respect of the Debt Securities of that series and this Indenture may
be served, and where Bearer Securities of that series and related Coupons may be
presented or surrendered for payment in the circumstances described in the
following paragraph (and not otherwise), (B) subject to any laws or regulations
applicable thereto, in a Place of Payment for that series which is located
outside the United States, an office or agency where Debt Securities of that
series and related Coupons may be presented and surrendered for payment
(including payment of any additional amounts payable on Securities of that
series, if so provided pursuant to Section 3.01); provided, however, that if the
Debt Securities of that series are listed on The Stock Exchange of the United
Kingdom and the Republic of Ireland, the Luxembourg Stock Exchange or any other
stock exchange located outside the United States and such stock exchange shall
so require, the Company will maintain a Paying Agent for the Debt Securities of
that series in London, Luxembourg or any other required city located outside the
United States, as the case may be, so long as the Debt Securities of that series
are listed on such exchange, and (C) subject to any laws or regulations
applicable thereto, in a Place of Payment for that series located outside the
United States, an office or agency where any Registered Securities of that
series may be surrendered for registration of transfer, where Debt Securities

                                       68
<PAGE>
 
of that series may be surrendered for exchange and where notices and demands to
or upon the Company in respect of the Debt Securities of that series and this
Indenture may be served.    The Company will give prompt written notice to the
Trustee of the location, and any change in the location, of such office or
agency.  If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee (in the case of Registered Securities) and
at the principal London office of the Trustee (in the case of Bearer
Securities), and the Company hereby appoints the Trustee as its agent to receive
all presentations, surrenders, notices and demands.

          No payment of principal, premium or interest on Bearer Securities
shall be made at any office or agency of the Company in the United States or by
check mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; provided, however, that
payment of principal of and any premium and interest on any Bearer Security
(including any additional amounts payable on Securities of such series, if so
provided pursuant to Section 3.01) shall be made at the office of the Company's
Paying Agent in the City of Boston, State of Massachusetts, if (but only if)
payment of the full amount of such principal, premium, interest or additional
amounts, as the case may be, at all offices or agencies outside the United
States maintained for the purpose by the Company in accordance with this
Indenture is illegal or effectively precluded by exchange controls or other
similar restrictions.

          The Company may also from time to time designate different or
additional offices or agencies to be maintained for  such purposes (in or
outside of such Place of Payment), and may from time to time rescind any such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligations described in the  preceding
paragraph.  The Company will give prompt written notice to the Trustee of any
such additional designation or rescission of designation and any change in the
location of any such different or additional office or agency.

          Section 12.04.  Money for Debt 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 Debt Securities and Coupons, if any, it will, on or
before each due date of the principal of (and premium, if any) or interest on
any of the Debt Securities of such 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 action or failure to so act.

                                       69
<PAGE>
 
          Whenever the Company shall have one or more Paying Agents with respect
to any series of Debt Securities and Coupons, it will, by or on each due date of
the principal (and premium, if any) or interest on any Debt Securities of such
series, deposit with any such 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 thereto, and (unless any such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of its action
or failure to so act.

          The Company will cause each Paying Agent other than the Trustee with
respect to any series of Debt Securities 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 Debt Securities of such series in trust for
     the benefit of the Persons entitled thereto until such sums shall be paid
     to such Persons or otherwise disposed of as herein provided;

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

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

          The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same 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 Debt Security of any series and remaining unclaimed for
two years after such principal (and premium, if any) or interest has become due
and payable shall be paid to the Company upon Company Request, or (if then held
by the Company) shall be discharged from such trust; and the Holder of such Debt
Security or Coupon shall thereafter, as an unsecured general creditor, look only
to the Company for payment thereof, and all liability of the Trustee

                                       70
<PAGE>
 
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 transmitted in the manner and to
the extent provided by Section 16.03, 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 notification, any unclaimed balance of such money then
remaining will be repaid to the Company.

          Section 12.05.  Corporate Existence.  Subject to Article Ten, the
Company will do or cause to be done all things necessary to preserve and keep in
full force and effect its corporate existence, rights (charter and statutory)
and franchises; provided, however, that the Company shall not be required to
preserve any such right or franchise if the Company shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company.

          Section 12.06.  Purchase of Debt Securities by Company.  If the Debt
Securities of a series are listed on the Stock Exchange of the United Kingdom
and the Republic of Ireland and such stock exchange shall so require, the
Company will not purchase any Debt Securities of that series by private treaty
at a price (exclusive of expenses and accrued interest) which exceeds 120% of
the mean of the nominal quotations of the Debt Securities of that series as
shown in The Stock Exchange Daily Official List for the last trading day
preceding the date of purchase.

          Section 12.07.  Waiver of Certain Covenants.  The Company may omit in
any particular instance to comply with any term, provision or condition set
forth in Section 12.05 (and, if so specified pursuant to Section 3.01, any other
covenant not set forth herein and specified pursuant to Section 3.01 to be
applicable to the Debt Securities of any series, except as otherwise provided
pursuant to Section 3.01) with respect to the Debt Securities of any series if
before the time for such compliance the Holders of at least a majority in
principal amount of the Outstanding Debt 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, but no such waiver
shall extend to or affect such term, provision or condition except to the extent
expressly so 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 13.01.  Applicability of Article.  Debt  Securities of any
series which are redeemable before their Maturity shall be redeemable in
accordance with their terms and (except as otherwise specified pursuant to
Section 3.01 for Debt Securities of any series) in accordance with this Article.

          Section 13.02.  Election to Redeem; Notice to Trustee.  The election
of the Company to redeem (or, in the case of Discount Securities, to permit the
Holders to elect to surrender for redemption) any Debt Securities shall be
evidenced by a Board Resolution.  In case of any redemption at the election of
the Company of less than all of the Debt Securities of any series pursuant to
Section 13.03, the Company shall, at least 60 days before the Redemption Date
fixed by the Company (unless a shorter notice shall be satisfactory to the
Trustee), notify the Trustee of such Redemption Date and of the principal amount
of Debt Securities of such series to be redeemed.  In the case of any redemption
of Debt Securities prior to the expiration of any restriction on such redemption

compliance with such restrictions.

Securities of any series are to be redeemed at the election of the Company, the
particular Debt Securities to be redeemed shall be selected not more than 60
days prior to the Redemption Date by the Trustee, from the Outstanding Debt
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 Debt Securities of such series or any integral multiple
thereof) of the principal amount of Debt Securities of such series in a
denomination larger than the minimum authorized denomination for Debt Securities
of such series pursuant to Section 3.02.  The portions of the principal amount
of Debt Securities so selected for partial redemption shall be equal to the
minimum authorized denominations for Debt Securities of such series pursuant to
Section 3.02 or any integral multiple thereof, except as otherwise set forth in
the applicable form of Debt Securities.  In any case when more than one
Registered Security of such series is registered in the same name, the Trustee
in its discretion may treat the aggregate principal amount so registered as if
it were represented by one Registered Security of such series.

                                       72

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

          Section 13.04.  Notice of Redemption.  Notice of 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, not less than 15 days (or 30 days if legally
required by DTC) and not more than 60 days prior to the Redemption Date to the
Holders of Debt Securities of any series to be redeemed in whole or in part
pursuant to this Article Thirteen, in the manner provided in Section 16.03.  Any
notice so given shall be conclusively presumed to have been duly given, whether
or not the Holder receives such notice.  Failure to give such notice, or any
defect in such notice to the Holder of any Debt Security of a series designated
for redemption, in whole or in part, shall not affect the sufficiency of any
notice of redemption with respect to the Holder of any other Debt Security of
such series.

          All notices of redemption shall state:

          (1)  the Redemption Date,

          (2)  the Redemption Price,

          (3)  that Debt Securities of such series are being redeemed by the
               Company pursuant to provisions contained in this Indenture or the
               terms of the Debt Securities of such series or a supplemental
               indenture establishing such series, if such be the case, together
               with a brief statement of the facts permitting such redemption,

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

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

                                       73
<PAGE>
 
          (6)  that, unless otherwise specified in such notice, Coupon
               Securities of any series, if any, surrendered for redemption must
               be accompanied by all Coupons maturing subsequent to the date
               fixed for redemption, failing which the amount of any such
               missing Coupon or Coupons will be deducted from the Redemption
               Price,

          (7)  the Place or Places of Payment where such Debt Securities are to
               be surrendered for payment of the Redemption Price,

          (8)  if Bearer Securities of any series are to be redeemed and any
               Registered Securities of such series are not to be redeemed, and
               if such Bearer Securities may be exchanged for Registered
               Securities not subject to redemption on this Redemption Date
               pursuant to Section 3.05(b) or otherwise, the last date on which
               such exchanges may be made, and

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

          Section 13.05.  Deposit of Redemption Price.  On or prior to the
Redemption Date for any Debt Securities, 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 12.04) an amount of
money sufficient to pay the Redemption Price of such Debt Securities or any
portions thereof which are to be redeemed on that date.

          Section 13.06.  Debt Securities Payable on Redemption Date.  Notice of
redemption having been given as aforesaid, any Debt Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
and from and after such date (unless the Company shall default in the payment of
the Redemption Price) such Debt Securities shall cease to bear interest.  Upon
surrender of any such Debt Security for redemption in accordance with said
notice, such Debt Security shall be paid by the Company at the Redemption Price;
provided, however, that installments of interest on Bearer Securities whose
Stated Maturity is on or prior to the Redemption Date shall be payable only at
an office or agency located outside the United States (except as otherwise
provided in Section 12.03) and, unless otherwise specified as contemplated by
Section 3.01, only upon presentation and surrender of Coupons for such interest;
and provided, further, that, unless otherwise specified as contemplated by
Section 3.01, installments of interest on Registered Securities which have a
Stated Maturity on or prior to the Redemption Date for such Debt Securities
shall be payable according to the terms of such Debt Securities and the
provisions of Section 3.07.

                                       74
<PAGE>
 
          If any Debt 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 Debt Security.

          If any Coupon Security surrendered for redemption shall not be
accompanied by all Coupons appertaining thereto maturing on or after the
Redemption Date, the Redemption Price for such Coupon Security may be reduced by
an amount equal to the face amount of all such missing Coupons.  If thereafter
the Holder of such Coupon shall surrender to any Paying Agent outside the United
States any such missing Coupon in respect of which a deduction shall have been
made from the Redemption Price, such Holder shall be entitled to receive the
amount so deducted.  The surrender of such missing Coupon or Coupons may be
waived by the Company and the Trustee, if there be furnished to them such
security or indemnity as they may require to save each of them and any Paying
Agent harmless.

          Section 13.07.  Debt Securities Redeemed in Part.  Any Debt Security
which is to be redeemed only in part shall be surrendered at the Corporate Trust
Office or such other office or agency of the Company as is specified pursuant to
Section 3.01 (in the case of Registered Securities) and at an office of the
Trustee or such other office or agency of the Company outside the United States
as is specified pursuant to Section 3.01 (in the case of Bearer Securities)
with, if the Company, the Security Registrar or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company, the Security Registrar 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
Debt Security without service charge, a new Debt Security or Debt Securities of
the same series of like tenor and form of any authorized denomination as
requested by such Holder in aggregate principal amount equal to and in exchange
for the unredeemed portion of the principal of the Debt Security so surrendered,
and, in the case of a Coupon Security, with appropriate Coupons attached.  In
the case of a Debt Security providing appropriate space for such notation, at
the option of the Holder thereof, the Trustee, in lieu of delivering a new Debt
Security or Debt Securities as aforesaid, may make a notation on such Debt
Security of the payment of the redeemed portion thereof.


                                ARTICLE FOURTEEN

                                 SINKING FUNDS

          Section 14.01.  Applicability of Article.  The provisions of this
Article shall be applicable to any sinking fund for the retirement of Debt
Securities of a series except as

                                       75
<PAGE>
 
otherwise specified pursuant to Section 3.01 for Debt Securities of such series.

          The minimum amount of any sinking fund payment provided for by the
terms of Debt 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 Debt Securities of any series is herein referred to as an
"optional sinking fund payment."  If provided for by the terms of Debt
Securities of any series, the amount of any cash sinking fund payment may be
subject to reduction as provided in Section 14.02.  Each sinking fund payment
shall be applied to the redemption of Debt Securities of any series as provided
for by the terms of Debt Securities of such series.

          Section 14.02.  Satisfaction of Mandatory Sinking Fund Payments with
Debt Securities.  In lieu of making all or any part of a mandatory sinking fund
payment with respect to any Debt Securities of a series in cash, the Company may
at its option, at any time no more than sixteen months and no less than 45 days
prior to the date on which such sinking fund payment is due, deliver to the
Trustee Debt Securities of such series (together with the unmatured Coupons, if
any, appertaining thereto) theretofore purchased or otherwise acquired by the
Company, except Debt Securities of such series which have been redeemed through
the application of mandatory sinking fund payments pursuant to the terms of the
Debt Securities of such series, accompanied by a Company Order instructing the
Trustee to credit such obligations and stating that the Debt Securities of such
series were originally issued by the Company by way of bona fide sale or other
negotiation for value, provided that such Debt Securities shall not have been
previously so credited.  Such Debt Securities shall be received and credited for
such purpose by the Trustee at the Redemption Price specified in such Debt
Securities for redemption through operation of the sinking fund and the amount
of such mandatory sinking fund payment shall be reduced accordingly.

          Section 14.03.  Redemption of Debt Securities for Sinking Fund.  Not
less than 60 days prior to each sinking fund payment date for any series of Debt
Securities (unless a shorter period shall be satisfactory to the Trustee), 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 Debt Securities of such series pursuant to Section
14.02 and whether the Company intends to exercise its rights to make a permitted
optional sinking fund payment with respect to such series.  Such certificate
shall be irrevocable and upon its delivery the Company shall be obligated to
make the cash payment or payments therein referred to, if any, on or before the
next succeeding sinking fund payment date.  In the case of the failure

                                       76
<PAGE>
 
of the Company to deliver such certificate, the sinking fund payment due on the
next succeeding sinking fund payment date for such series shall be paid entirely
in cash and shall be sufficient to redeem the principal amount of the Debt
Securities of such series subject to a mandatory sinking fund payment without
the right to deliver or credit Debt Securities as provided in Section 14.02 and
without the right to make any optional sinking fund payment with respect to such
series at such time.

          Any sinking fund payment or payments (mandatory or optional) made in
cash plus any unused balance of any preceding sinking fund payments made with
respect to the Debt Securities of any particular series shall be applied by the
Trustee (or by the Company if the Company is acting as its own Paying Agent) on
the sinking fund payment date on which such payment is made (or, if such payment
is made before a sinking fund payment date, on the sinking fund payment date
immediately following the date of such payment) to the redemption of Debt
Securities of such series at the Redemption Price specified in such Debt
Securities with respect to the sinking fund.  Any sinking fund moneys not so
applied or allocated by the Trustee (or by the Company if the Company is acting
as its own Paying Agent) to the redemption of Debt Securities shall be added to
the next sinking fund payment received by the Trustee (or if the Company is
acting as its own Paying Agent, segregated and held in trust as provided in
Section 12.04) for such series and, together with such payment (or such amount
so segregated), shall be applied in accordance with the provisions of this
Section.  Any and all sinking fund moneys with respect to the Debt Securities of
any particular series held by the Trustee (or if the Company is acting as its
own Paying Agent, segregated and held in trust as provided in Section 12.04) on
the last sinking fund payment date with respect to Debt Securities of such
series and not held for the payment or redemption of particular Debt Securities
of such series shall be applied by the Trustee (or by the Company if the Company
is acting as its own Paying Agent), together with other moneys, if necessary, to
be deposited (or segregated) sufficient for the purpose, to the payment of the
principal of the Debt Securities of such series at Maturity.

          The Trustee shall select or cause to be selected the Debt Securities
to be redeemed upon such sinking fund payment date in the manner specified in
Section 13.03 and the Company shall cause notice of the redemption thereof to be
given in the manner provided in Section 13.04.  Such notice having been duly
given, the redemption of such Debt Securities shall be made upon the terms and
in the manner stated in Section 13.06.

          On or before each sinking fund payment date, the Company shall pay to
the Trustee (or, if the Company is acting as its own Paying Agent, the Company
shall segregate and hold in trust as provided in Section 12.04) in cash a sum
equal to the principal and any interest accrued to the Redemption Date for

                                       77
<PAGE>
 
Debt Securities or portions thereof to be redeemed on such sinking fund payment
date pursuant to this Section.

          Neither the Trustee nor the Company shall redeem any Debt Securities
of a series with sinking fund moneys or mail any notice of redemption of Debt
Securities of such series by operation of the sinking fund for such series
during the continuance of a Default in payment of interest, if any, on any Debt
Securities of such series or of any Event of Default (other than an Event of
Default occurring as a consequence of this paragraph) with respect to the Debt
Securities of such series, except that if the notice of redemption shall have
been provided in accordance with the provisions hereof, the Trustee (or the
Company, if the Company is then acting as its own Paying Agent) shall redeem
such Debt Securities if cash sufficient for that purpose shall be deposited with
the Trustee (or segregated by the Company) for that purpose in accordance with
the terms of this Article.   Except as aforesaid, any moneys in the sinking fund
for such series at the time when any such Default or Event of Default shall
occur and any moneys thereafter paid into such sinking fund shall, during the
continuance of such Default or Event of Default, be held as security for the
payment of the Debt Securities and Coupons, if any, of such series; provided,
however, that in case such Default or Event of Default shall have been cured or
waived as provided herein, such moneys shall thereafter be applied, on or prior
to the next sinking fund payment date for the Debt Securities of such series on
which such moneys may be applied, pursuant to the provisions of this Section.

                                   DEFEASANCE

          Section 15.01.  Applicability of Article.  If, pursuant to Section
3.01, provision is made for the defeasance of Debt Securities of a series, then
the provisions of this Article shall be applicable except as otherwise specified
pursuant to Section 3.01 for Debt Securities of such series.  Defeasance
provisions, if any, for Bearer Securities may be specified pursuant to Section
3.01.

          Section 15.02.  Defeasance Upon Deposit of Moneys or U.S. Government
Obligations.  At the Company's option, either (a) the Company shall be deemed to
have been Discharged (as defined below) from its obligations with respect to
Debt Securities of any series ("legal defeasance option") or (b) the Company
shall cease to be under any obligation to comply with any term, provision or
condition set forth in Sections 7.04(1) and 10.01 with respect to Debt
Securities of any series (and, if so specified pursuant to Section 3.01, any
other obligation of the Company or restrictive covenant added for the benefit of
such series pursuant to Section 3.01) ("covenant defeasance option")

                                       78
<PAGE>
 
at any time after the applicable conditions set forth below have been satisfied:

          (1) the Company shall have deposited or caused to be deposited
     irrevocably with the Trustee as trust funds in trust for, and dedicated
     solely to, the benefit of the Holders of the Debt Securities of such series
     (i) money in an amount, or (ii) U.S. Government Obligations (as defined
     below) which through the payment of interest and principal in respect
     thereof in accordance with their terms will provide, not later than one day
     before the due date of any payment, money in an amount, or (iii) a
     combination of (i) and (ii), 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 each
     installment of principal (including any mandatory sinking fund payments) of
     and premium, if any, and interest on, the Outstanding Debt Securities of
     such series on the dates such installments of interest or principal and
     premium are due;

          (2) such deposit shall not cause the Trustee with respect to the Debt
     Securities of that series to have a conflicting interest as defined in
     Section 6.08 and for purposes of the Trust Indenture Act with respect to
     the Debt Securities of any series;

          (3) such deposit will 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 (other
     than such a breach, violation or Default (a) with respect to Indebtedness
     of the Company which is defeased, redeemed or otherwise satisfied prior to
     or contemporaneously with such deposit, or (b) which is consented to or
     waived by the other relevant party to such agreement or instrument);

          (4) with respect to the legal defeasance option only, no Event of
     Default under Section 5.01(6) or Section 5.01(7) or event which with the
     giving of notice or lapse of time, or both, would become an Event of
     Default under Section 5.01(6) or Section 5.01(7) shall have occurred and be
     continuing on the 91st day after the date of such deposit; and

          (5) the Company shall have delivered to the Trustee an Opinion of
     Counsel or a ruling from the Internal Revenue Service to the effect that
     the Holders of the Debt Securities of such series will not recognize
     income, gain or loss for federal income tax purposes as a result of such
     deposit, defeasance or Discharge.

          "Discharged" means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by,

                                       79
<PAGE>
 
and obligations under, the Debt Securities of such series and to have satisfied
all the obligations under this Indenture relating to the Debt Securities of such
series (and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), except (A) the rights of Holders of Debt
Securities of such series to receive, from the trust fund described in clause
(1) above, payment of the principal of (and premium, if any) and interest on
such Debt Securities when such payments are due, (B) the Company's obligations
with respect to the Debt Securities of such series under Section 3.04, 3.05,
3.06, 12.03 and 15.03 and (C) the rights, powers, trusts, duties and immunities
of the Trustee hereunder.

          "U.S. Government Obligations" means securities that are (i) direct
obligations of the United States for the payment of which its full faith and
credit is pledged, or (ii) obligations of a Person controlled or supervised by
and acting as an agency or instrumentality of the United States the payment of
which is unconditionally guaranteed as a full faith and credit obligation by the
United States, which, in either case under clauses (i) or (ii), are not callable
or redeemable at the option of the issuer thereof, and shall also include a
depository receipt issued by a bank or trust company as custodian with respect
to any such U.S. Government Obligation or a specific payment of interest on or
principal of any such U.S. Government Obligation held by such custodian for the
account of the holder of a 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 interest on or principal of the U.S. Government Obligation evidenced by such
depository receipt.

          Section 15.03.  Deposited Moneys and U.S. Government Obligations to Be
Held in Trust.  All moneys and U.S. Government Obligations deposited with the
Trustee pursuant to Section 15.02 in respect of Debt Securities of a series
shall be held in trust and applied by it, in accordance with the provisions of
such Debt 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 Debt Securities, of all
sums due and to become due thereon for principal (and premium, if any) and
interest, if any, but such money need not be segregated from other funds except
for funds of the Company and except to the extent required by law.

          Section 15.04.  Repayment to Company.  The provisions of the last
paragraph of Section 12.04 shall apply to any money held by the Trustee or any
Paying Agent under this Article that remains unclaimed for two years after the
Maturity of any series of Debt Securities for which money or U.S. Government
Obligations have been deposited pursuant to Section 15.02.

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

          Notices to the Company or the Trustee shall only be deemed given when
received by the Company or the Trustee, as the case may be.

          Section 16.03.  Notice to Holders; Waiver.  When this Indenture
provides for notice to Holders of any event, (1) such notice shall be
sufficiently given to Registered Holders (unless otherwise herein expressly
provided) if in writing and mailed,

                                       81
<PAGE>
 
first-class postage prepaid, to such Registered Holders as their names and
addresses appear in the Security Register, within the time prescribed, and (2)
such notice shall be sufficiently given to Holders of Bearer Securities or
Coupons (unless otherwise herein expressly provided) if published at least twice
in an Authorized Newspaper or Newspapers in New York City and, if Debt
Securities of such series are then listed on The Stock Exchange of the United
Kingdom and the Republic of Ireland or the Luxembourg Stock Exchange or any
other stock exchange located outside the United States and such stock exchange
shall so require, in a daily newspaper in London or Luxembourg or in such other
city or cities specified pursuant to Section 3.01, the first such publication to
be not earlier than the earliest date and not later than two Business Days prior
to the latest date prescribed for the giving of such notice; provided, however,
that, in any case, any notice to Holders of Floating Rate Securities regarding
the determination of a periodic rate of interest, if such notice is required
pursuant to Section 3.01, shall be sufficiently given if given in the manner
specified pursuant to Section 3.01.

          In the event of suspension of regular mail service or by reason of any
other cause it shall be impracticable to give notice by mail, such notification
as shall be given with the approval of the Trustee shall constitute sufficient
notice for every purpose hereunder.
 
          In the event of suspension of publication of any Authorized Newspapers
or by reason of any other cause it shall be impracticable to give notice by
publication, such notification as shall be given with the approval of the
Trustee shall constitute sufficient notice for every purpose hereunder.

          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 on such waiver.  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, and any notice which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given.  In any case
where notice to Holders is given by publication, any defect in any notice so
published as to any particular Holder shall not affect the sufficiency of such
notice with respect to other Holders, and any notice which is published in the
manner herein provided shall be conclusively presumed to have been duly given.

whether the Holders of the required principal amount of Debt Securities of any
series have concurred in any direction, waiver or consent, Debt Securities owned
by the Company or by any Person directly or indirectly controlling or controlled
by or under direct or indirect common control with the Company shall be
disregarded and deemed not to be outstanding, except that, for the purpose of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Debt Securities which the Trustee knows are
so owned shall be so disregarded.  Also, subject to the foregoing, only Debt
Securities of a series outstanding at the time shall be considered in any such
determination.

that series, then (notwithstanding any other provision of this Indenture or of
the Debt Securities or Coupons) payment of principal (and premium, if any) or
interest 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, Redemption Date or at the
Stated Maturity, and no interest shall accrue on the amount so payable for the
period from and after such Interest Payment Date, Redemption Date or Stated
Maturity, as the case may be, to such Business Day if such payment is made or
duly provided for on such Business Day.

          Section  16.10.  Governing Law.  THE LAWS OF THE STATE OF NEW YORK

any liability for any obligations of the Company or the Trustee under the Debt
Securities, the Coupons or this Indenture or for any claim based on, in respect
of or by reason of such obligations or their creation.  By accepting a Debt
Security, each Holder of Debt Securities shall waive and release all such

issue of the Debt Securities.

          Section  16.12.  Successors and Assigns.  All covenants and agreements

cross-reference sheet and headings of the Articles and Sections of this

          "Pledge Agreement" shall have the meaning specified in Section
17.05(a).

          Section 17.02  Method of Exchange.  (a)  In order to exercise the
right of exchange in respect of any Exchangeable Security, the Holder of such
Exchangeable Security to be exchanged shall surrender such Exchangeable Security
to the Collateral Agent for exchange by delivering such Exchangeable Security
to, or mailing such Exchangeable Security by registered mail, postage prepaid,
addressed to the Collateral Agent at the office or agency of the Collateral
Agent maintained for that purpose, accompanied in each case by written notice to
the Company and the Collateral Agent that the Holder elects to exchange such
Exchangeable Security, or, if less than the entire principal amount of such
Exchangeable Security is to be exchanged, the portion thereof to be exchanged.
Such notice shall also state the name or names (with address) in which the
certificate or certificates for Kaiser Common Shares or, to the extent
applicable, other Exchange Property issuable upon such exchange shall be issued,
subject to compliance with applicable federal and state securities laws.
Exchangeable Securities surrendered for exchange shall be accompanied (if so
required by the Company or the Collateral Agent) by proper assignments thereof
to the Company or in blank for transfer.  If Exchangeable Securities not called
for redemption are surrendered for exchange during the period from the close of
business on a record date for the payment of interest and prior to the next
succeeding interest payment date relating thereto, such Exchangeable Securities
must be accompanied by funds equal to the interest payable on such succeeding
interest payment date on the principal amount so exchanged.  Any exchange of an
Exchangeable Security pursuant to this Article Seventeen shall be deemed to have
been effected immediately prior to the close of business on the date on which
such Exchangeable Security shall have been properly surrendered for exchange
(the "Exchange Date"), which, subject to the provisions of Section 17.09(g),
shall be the date on which such Exchangeable Security and notice and any such
required assignment (and, if required, funds equal to the interest payable on
the next succeeding interest payment date on the principal amount exchanged)
shall be received by the Collateral Agent.  Unless the exchange is registered
under the Securities Act prior to delivery of Exchange Property to the Holder,
such Holder also shall deliver evidence satisfactory to Kaiser and the Company
(which may include an opinion of counsel if requested by Kaiser or the Company),
that such exchange is exempt from registration under the Securities Act.

          (b) Within two Business Days after the Exchange Date, the Company
shall deliver to the Collateral Agent written notice of whether the Company
shall (i) deliver Exchange Property or (ii) pay cash (the "Cash Payment
Election") in lieu of Kaiser Common Shares or other Marketable Securities
included in the Exchange Property, in whole or in part (indicating the
respective

                                       89
<PAGE>
 
portions to be so delivered or paid), pursuant to Section 17.10 and deliver
Exchange Property as to which the Cash Payment Election is not exercised.  If no
such notice is delivered within such two-Business Day period, the Company will
be irrebuttably presumed to have elected to deliver Exchange Property.  To the
extent the Company shall have so notified the Collateral Agent that it will
exercise the Cash Payment Election in respect of such exchange, the exchange
shall be made in accordance with the provisions of Section 17.10.  To the extent
the Company shall not have exercised a Cash Payment Election in respect of such
exchange, the Company shall deliver or cause the Collateral Agent to deliver, no
later than the seventh Business Day following such Exchange Date (subject to
subparagraph (c) of this Section 17.02), at said office or agency to such
Holder, or on such Holder's written order, (i) a certificate or certificates for
the number of full Kaiser Common Shares or securities constituting other
Exchange Property as to which the Cash Payment Election is not exercised
deliverable upon the exchange of such Exchangeable Security (or specified
portion thereof), (ii) other Exchange Property (other than cash), if any,
apportioned thereto and (iii) a check for any cash apportioned thereto.
Provision shall be made for any fractional interests in Kaiser Common Shares or
other Exchange Property as provided in Section 17.03.  Immediately prior to the
close of business on the Exchange Date, the rights of the Holder of such
Exchangeable Security as a Holder shall cease and the Person or Persons in whose
name or names any certificate or certificates for Kaiser Common Shares or other
Exchange Property shall be deliverable upon such exchange shall, as between such
Person or Persons and the Company, be entitled to receive (and shall be deemed
to have become the holder or holders of record of) the Kaiser Common Shares or
other Exchange Property represented thereby, or cash in lieu thereof if and to
the extent a Cash Payment Election has been exercised.  From and after such
time, the interests of the Holder shall be limited to the right to receive such
Kaiser Common Shares and other Exchange Property, or cash in lieu thereof as
aforesaid.

          (c) Delivery of (i) such certificate or certificates, property or
securities, if any, apportioned thereto, and a check for any cash apportioned
thereto and for cash in lieu of fractional interests as aforesaid or (ii) a
check for cash in lieu of Kaiser Common Shares or other Marketable Securities
included in the Exchange Property as provided in Section 17.10, may be delayed,
with respect to any portion of the Exchange Property or cash equivalent thereof
deliverable upon such exchange, for a reasonable period of time at the request
of the Company (which request shall be made by an Officers' Certificate
specifying the reasons for such delay) in order to (A) effectuate the
calculation of any adjustments with respect to such portion of the Exchange
Property or cash equivalent thereof deliverable upon such exchange pursuant to
this Article Seventeen, (B) obtain any certificate representing securities to be
delivered (other than Kaiser Common Shares), (C) complete any reapportionment of
the Kaiser Common Shares or other Exchange Property which is

                                       90
<PAGE>
 
required by this Article Seventeen or (D) comply with any applicable law
(including, to the extent applicable, the Trust Indenture Act, or any
registration under the Securities Act as contemplated by Section 17.15 hereof);
provided, however, that the Company shall be required to deliver within the
applicable time period specified in subparagraph (b) of this Section 17.02 or
subparagraph (a) of Section 17.10, as the case may be, that portion of the
Exchange Property or cash equivalent thereof deliverable upon such exchange for
which such delay is not necessary.  No delay pursuant to this subparagraph shall
affect the requirement that any election by the Company to exercise the Cash
Payment Election must be made within two Business Days after the Exchange Date.
If the Exchange Property includes securities and if, between the date an
exchange under this Section 17.02 is deemed effected and the date of delivery of
such securities, such securities shall cease to have any or certain rights, or a
record date or effective date of a transaction to which Section 17.04, 17.05 or
17.08 applies shall occur, the Person entitled to receive such securities shall
be entitled only to receive such securities as so modified and any dividends or
proceeds received thereon on or after the date such exchange is deemed effected,
and none of the Company, the Trustee and the Collateral Agent shall be otherwise
liable with respect to the modification of such securities from the date such
exchange is deemed effected and the date of such delivery.

          (d) Except as otherwise expressly provided in this Article Seventeen,
no payment or adjustment shall be made upon any exchange on account of any
interest accrued on the Exchangeable Securities surrendered for exchange or on
account of any dividends on the Kaiser Common Shares or other Exchange Property
delivered upon such exchange; provided, however, that interest accrued on any
Exchangeable Securities surrendered for exchange on or after any record date for
payment of interest and before any interest payment date relating thereto shall
be paid to, as applicable, the Holder of record as of such record date.

          (e) In the case of any Exchangeable Security which is exchanged in
part only, upon such exchange the Company shall execute and the Trustee shall
authenticate and deliver to the Holder thereof, at the expense of the Company
except for transfer taxes in the case that the new Exchangeable Security is to
be registered in a name different than that in which the old Exchangeable
Security was issued, a new Exchangeable Security or Exchangeable Securities of
authorized denominations in principal amount equal to the unexchanged portion of
such Exchangeable Security.

          (f) Anything in this Article Seventeen to the contrary
notwithstanding, if there has occurred and is continuing an Event of Default
with respect to the Exchangeable Securities of any series and the maturity of
the Exchangeable Securities of such series has been accelerated pursuant to
Section 5.02, the Trustee shall promptly give notice thereof to all Holders of
Exchangeable

                                       91
<PAGE>
 
Securities of such series in the manner provided in Section 16.03 (which notice
shall be in addition to any notice under Article Five or Section 6.02).  In such
event, (i) during the 45-day period commencing on the date such notice is
mailed, the Collateral Agent shall not sell or otherwise dispose of any
Collateral, (ii) Exchangeable Securities of such series may be exchanged if the
Exchange Date occurs during such 45-day period, in accordance with this Article
Seventeen, and (iii) at the close of business on the last day of such 45-day
period, the exchange rights of the Exchangeable Securities of such series
pursuant to this Article shall terminate and the Collateral Agent may thereafter
sell or otherwise dispose of any Collateral or take any other action permitted
or authorized under the terms of this Indenture and the Pledge Agreement.  Such
notice sent by the Trustee to all Holders of Exchangeable Securities of such
series shall state the information contained in clauses (i) through (iii) of the
preceding sentence.  Notwithstanding the foregoing, if (A) all Events of Default
with respect to the Exchangeable Securities of such series shall no longer be
continuing and (B) any acceleration of the Exchangeable Securities of such
series arising therefrom shall have been rescinded, and if the Trustee or the
Collateral Agent shall hold Exchange Property sufficient to be delivered in
exchange for all Exchangeable Securities of such series then outstanding
(assuming no exercise by the Company of the Cash Payment Election), then the
exchange rights of the Exchangeable Securities of such series pursuant to this
Article shall immediately be reinstated and may thereafter be exercised as
provided in this Article, and the Trustee shall promptly transmit notice of such
reinstatement to all Holders of the Exchangeable Securities of such series.

          Section 17.03  Fractional Interests.  No fractional Kaiser Common
Shares or fractional interest in other securities or property included in the
Exchange Property shall be delivered upon exchange of Exchangeable Securities.
If more than one Exchangeable Security of the same series shall be surrendered
for exchange at one time by the same Holder, the number of full shares or whole
interests in other securities or property which shall be delivered upon exchange
shall be computed on the basis of the aggregate principal amount of the
Exchangeable Securities of the same series (or specified portions thereof to the
extent permitted hereby) so surrendered.  Instead of any fractional Kaiser
Common Shares (or other fractional interest) which otherwise would be
deliverable upon exchange of any Exchangeable Security or Exchangeable
Securities (or specified portions thereof), the Collateral Agent on behalf of
the Company shall pay a cash adjustment in respect of such fractional interest
in an amount equal to the same fraction of the Market Price per share of the
Kaiser Common Shares (or the same fraction of the Market Price of a whole
interest in the other securities or property) on the Business Day next preceding
the Exchange Date.  The Collateral Agent shall obtain the funds for payment of
such fractional interests by, at the direction of the Company, (i) the sale of
Kaiser Common Shares held by it, to the extent that after

                                       92
<PAGE>
 
such sale the number of whole Kaiser Common Shares remaining on deposit with the
Collateral Agent shall be sufficient to allow the exchange of all outstanding
Exchangeable Securities for whole Kaiser Common Shares on the basis of the then
applicable Exchange Rate, (ii) the sale of whole interests in other securities
or property held by it and included in the Exchange Property or (iii) sufficient
cash contributions from the Company.  The Company agrees to furnish any
additional moneys required to permit such payment, and shall have the right to
prompt reimbursement thereof by the Collateral Agent upon request therefor out
of any cash included in the Exchange Property.

          Section 17.04  Adjustment of Exchange Rate.  The Exchange Rate shall
be subject to adjustment as follows:

          (a) In the event (i) Kaiser shall pay a dividend or make a
distribution with respect to Kaiser Common Stock in shares of Kaiser Common
Stock, (ii) Kaiser shall subdivide or split the outstanding shares of Kaiser
Common Stock into a greater number of shares of Kaiser Common Stock or (iii)
Kaiser shall combine the outstanding shares of Kaiser Common Stock into a
smaller number of shares of Kaiser Common Stock, the Exchange Rate in effect
immediately prior thereto shall be proportionately adjusted pursuant to this
Section 17.04 so that the Holder of any Exchangeable Securities thereafter
surrendered for exchange shall be entitled (subject to Section 17.10 hereof) to
receive the number of Kaiser Common Shares which such Holder would have owned or
have been entitled to receive after the happening of any of the events described
above had such Exchangeable Securities been exchanged immediately prior to the
record date (or, if there is no record date, the effective date) of such event.
Such adjustments shall be made whenever any of the events listed above shall
occur and shall become effective as of immediately after the close of business
on the record date (in the case of a stock dividend) or the effective date (in
the case of a subdivision, split or combination).  Any Holder surrendering any
Exchangeable Securities for exchange after such record date or such effective
date, as the case may be, shall be entitled to receive Kaiser Common Shares at
the Exchange Rate as so adjusted pursuant to this Section 17.04, in addition to
any other Exchange Property apportioned thereto.

          (b) In the event that, pursuant to Section 17.09, Kaiser Common Shares
otherwise deliverable upon exchange of the Exchangeable Securities of any series
are tendered or exchanged and not withdrawn as of the last time (the "Expiration
Time") tenders or exchanges may be made pursuant to a tender or exchange offer
(as it shall have been amended) for shares of Kaiser Common Stock, the Exchange
Rate in effect immediately prior to the Expiration Time shall be adjusted by
multiplying such Exchange Rate by a fraction, the numerator of which shall be
the total number of Kaiser Common Shares then deliverable upon exchange of all
outstanding Exchangeable Securities of such series less the number of Kaiser
Common Shares sold or exchanged in such tender

                                       93
<PAGE>
 
or exchange offer, and the denominator of which shall be the total number of
Kaiser Common Shares then deliverable upon exchange of all outstanding
Exchangeable Securities of such series (including any Kaiser Common Shares sold
or exchanged in such tender or exchange offer).  Such adjustments shall be made
whenever the above shall occur and shall become effective as of immediately
prior to the opening of business on the day following the Expiration Time.  Any
Holder surrendering any Exchangeable Securities of such series for exchange
after the opening of business on the day following the Expiration Time shall be
entitled (subject to Section 17.10 hereof) to receive Kaiser Common Shares at
the Exchange Rate as so adjusted pursuant to this Section 17.04, in addition to
any other Exchange Property apportioned thereto.

          (c) Notwithstanding the foregoing provisions, no adjustment in the
Exchange Rate shall be required unless such adjustment would require an increase
or decrease in such Exchange Rate of more than 1%; provided, however, that any
adjustments which by reason of this subparagraph (c) are not made shall be
carried forward and taken into account in any subsequent adjustment.

          (d) All calculations under this Section 17.04 shall be made to the
nearest one-ten-thousandth (.0001) of a share.

          (e) Whenever the Exchange Rate is adjusted as provided herein, the
Company shall determine the adjusted Exchange Rate in accordance with this
Section 17.04 and shall prepare a certificate setting forth such adjusted
Exchange Rate and any other Exchange Property apportioned to the Kaiser Common
Shares and showing in detail the facts upon which such adjustments are based,
and such certificate shall forthwith be filed with the Trustee and the
Collateral Agent.  A notice stating that the Exchange Rate has been adjusted and
setting forth the adjusted Exchange Rate and any other Exchange Property
apportioned to the Kaiser Common Shares shall, as soon as practicable, be mailed
(in the manner provided in Section 16.03) by or on behalf of the Company to the
Holders of Exchangeable Securities at their last addresses as they shall appear
upon the Security Register maintained pursuant to Section 3.05(a) of this
Indenture.

          Section 17.05  Pledge Agreement; Company Instructions Concerning
Exchange Property.  (a)  The Company, simultaneously with or prior to the first
issuance of Exchangeable Securities of any series, shall enter into a pledge
agreement substantially in the form attached as Exhibit C hereto (such pledge
agreement, as it may be amended, amended and restated, supplemented or otherwise
modified from time to time being herein called the "Pledge Agreement") with the
Trustee, as collateral agent (the "Collateral Agent"), pursuant to which the
Company shall deposit with the Collateral Agent a number of shares of Kaiser
Common Stock equal to the aggregate number of shares of Kaiser Common Stock for
which such Exchangeable Securities will be exchangeable

                                       94
<PAGE>
 
at the Exchange Rate in effect on the date of issuance of such Exchangeable
Securities (assuming no exercise by the Company of the Cash Payment Election),
which initially shall constitute the Exchange Property, and granting the
Collateral Agent a first priority security interest therein for the ratable
benefit of the Holders of such Exchangeable Securities.  Subsequent to the first
issuance of Exchangeable Securities of any series, no additional Exchangeable
Securities of such series may be issued unless, simultaneously with or
immediately prior to the issuance of such additional Exchangeable Securities,
there is on deposit with the Collateral Agent pursuant to the Pledge Agreement a
number of Kaiser Common Shares, and an amount of any other Exchange Property,
equal to the aggregate number of Kaiser Common Shares, and the aggregate amount
of any other Exchange Property, for which the outstanding Exchangeable
Securities of such series (after giving effect to the issuance of such
additional Exchangeable Securities) would be exchangeable on the date of
issuance of such additional Exchangeable Securities (assuming no exercise by the
Company of the Cash Payment Election).

          (b) In case there shall be, at any time while any Exchangeable
Securities are outstanding, a dividend or distribution of securities or other
property (other than (i) cash, (ii) dividends, subdivisions and combinations for
which an adjustment in the Exchange Rate is made pursuant to Section 17.04(a),
(iii) securities or other property received in a transaction to which Section
17.08 hereof applies, and (iv) subscription rights, options, warrants or other
similar rights to which subparagraph (c) of this Section 17.05 applies) on
Exchange Property, including the receipt of securities or other non-cash
proceeds of the sale of any Exchange Property pursuant to a tender or exchange
offer as permitted by Section 17.09, the Company, within five Business Days
after the date of such dividend or distribution, may, at its option, instruct
the Collateral Agent to sell any or all securities and other property so
received by way of such dividend or distribution in an arm's length transaction
to a Person that is not an Affiliate of the Company for cash in such manner as
the Company may instruct in writing; provided, however, that if the Company has
at the same time received securities or other property as a dividend or
distribution on similar securities or other property that is not Exchange
Property, such sale shall be in proportion to, and on the same terms as, such
securities or other property received by the Company as a dividend or
distribution on similar securities or other property that is not Exchange
Property are sold for cash by the Company in an arm's length transaction to a
Person that is not an Affiliate of the Company.  Such instructions shall be
accompanied by an Officers' Certificate specifying the amount of securities and
other property to be sold, and the amount and terms of sale by the Company of
such securities and other property that is not Exchange Property.  In the
absence of such instructions, or if the Company has at the same time received
securities or other property as a dividend or distribution on similar securities
or other property that is not Exchange

                                       95
<PAGE>
 
Property and the Company is not selling such securities or property that is not
Exchange Property as aforesaid, the Collateral Agent shall retain and hold such
securities and other property received by it in respect of Exchange Property,
and such securities or other property retained and held, together with the
proceeds of any such sale pursuant to the preceding sentence, shall be
additional Exchange Property for apportionment equally among the Kaiser Common
Shares and other Exchange Property for which Exchangeable Securities are
exchangeable as of immediately after the close of business on the record date
for the dividend or distribution to which this Section 17.05(b) applies, or, if
there is no such record date, the effective date of such dividend or
distribution (or, in the case of the receipt of securities or other property as
proceeds of the sale of any Exchange Property pursuant to a tender or exchange
offer as permitted by Section 17.09, as of immediately prior to the opening of
business on the day following the Expiration Time for such tender or exchange
offer).

          (c) In case there shall be, at any time while any Exchangeable
Securities are outstanding, a dividend or distribution of any subscription
rights, options, warrants or other similar rights with respect to any Exchange
Property, including the receipt of subscription rights, options, warrants or
other similar rights as proceeds of the sale of any Exchange Property pursuant
to a tender or exchange offer as permitted by Section 17.09, the Company shall,
after the date of such dividend or distribution (or, in the case of the receipt
of subscription rights, options, warrants or other similar rights as proceeds of
the sale of any Exchange Property pursuant to a tender or exchange offer as
permitted by Section 17.09, after the Expiration Time for such tender or
exchange offer) either:

               (1) instruct the Collateral Agent to sell any rights so
     distributed in an arm's length transaction to a Person that is not an
     Affiliate of the Company for cash in such manner as the Company may
     instruct in writing;

               (2) instruct the Collateral Agent to retain and hold such rights;
     provided, however, that such rights shall not be allowed to expire
     unexercised so long as they are in the money and if otherwise feasible;

               (3) to the extent there is sufficient cash among the Exchange
     Property or to the extent the Company causes the sale of Exchange Property
     (other than Kaiser Common Shares) to provide sufficient cash among the
     Exchange Property, instruct the Collateral Agent in writing to exercise any
     rights so distributed (with such amount of cash, if any, resulting from
     such sale and not necessary to exercise such rights being held as Exchange
     Property for apportionment equally among the Kaiser Common Shares and other
     Exchange Property) and to thereafter either (i) retain and hold any
     securities and other property received upon

                                       96
<PAGE>
 
     exercise of such rights, (ii) cause the sale of some or all of such
     securities or other property received upon exercise of such rights in an
     arm's length transaction to a Person which is not an Affiliate of the
     Company or (iii) cause the pro rata distribution of such securities or
     other property received upon exercise of such rights to Holders of
     Exchangeable Securities; or

               (4) instruct the Collateral Agent to cause such rights to be
     distributed pro rata to the Holders of record of Exchangeable Securities on
     the Security Register as of immediately after the close of business on the
     record date (and if there is no record date, the close of business on the
     effective date) for such dividend or distribution (or, in the case of the
     receipt of subscription rights, options, warrants or other similar rights
     as proceeds of the sale of any Exchange Property pursuant to a tender or
     exchange offer as permitted by Section 17.09, as of immediately prior to
     the opening of business on the day following the Expiration Time for such
     tender or exchange offer).

In the event option (1), (2) or (3) above is chosen, the proceeds of any such
sale and any such securities or other property retained and held shall be
additional Exchange Property for apportionment equally among other Exchange
Property for which Exchangeable Securities are exchangeable as of immediately
after the close of business on the record date for the dividend or distribution
to which this Section 17.05(c) applies, or, if there is no such record date, the
effective date of such dividend or distribution (or, in the case of the receipt
of subscription rights, options, warrants or other similar rights as proceeds of
the sale of any Exchange Property pursuant to a tender or exchange offer as
permitted by Section 17.09, as of immediately prior to the opening of business
on the day following the Expiration Time for such tender or exchange offer).
Notwithstanding the foregoing, if (after giving effect to any dividend or
distribution referred to in this Section 17.05(c)) the Company owns other such
subscription rights, options, warrants or similar rights which are not Exchange
Property, and if there is sufficient cash among the Exchange Property to
exercise such subscription rights, options, warrants or similar rights included
in the Exchange Property, any sale or exercise of subscription rights, options,
warrants or similar rights (or sale of any securities and other property
received upon exercise of such rights) caused by the Company pursuant to clause
(1) or clause (3) of this Section 17.05(c) may be caused by the Company only pro
rata in the same proportion as the Company so acts (and, in the case of a sale,
on the same terms as the Company sells in an arm's-length transaction to a
Person that is not an Affiliate of the Company) with respect to the subscription
rights, options, warrants or similar rights or securities or other property
received upon exercise of such rights, as the case may be, owned by the Company
which are not Exchange Property.  Any instructions given pursuant to this
Section 17.05(c) shall be accompanied by

                                       97
<PAGE>
 
an Officers' Certificate specifying the amount of securities and other property
to be sold, exercised or distributed, as the case may be, and the amount and
terms of sale or exercise by the Company of such securities and other property
that is not Exchange Property.

          (d) In case there shall be an Extraordinary Cash Distribution (other
than a transaction to which Section 17.08 hereof applies) such dividend or
distribution shall be held as Exchange Property for apportionment equally among
the Kaiser Common Shares and other Exchange Property for which Exchangeable
Securities are exchangeable as of immediately after the close of business on the
record date for such dividend or distribution to which this Section 17.05(d)
applies or, if there is no record date, the effective date of such dividend or
distribution.

          (e) The amount of dividends or other distributions allocable to
Exchange Property (or the amount of proceeds resulting from any sale or exchange
of Exchange Property) pursuant to this Article Seventeen shall be determined
without regard to any tax obligations of the Company or the Collateral Agent.
Upon any dividend or distribution or other transaction with respect to Exchange
Property which is taxable or treated as being taxable to the Company or the
Collateral Agent, the Company shall pay, or shall deposit with the Collateral
Agent sufficient additional cash and shall cause the Collateral Agent to pay,
the taxes of the Company and/or the Collateral Agent arising from such dividend,
distribution or other transaction.  In no event will Exchange Property or a
distribution or dividend allocable thereto or proceeds of any sale thereof be
used to satisfy any tax obligations of the Company or the Collateral Agent
arising from any such dividend, distribution or other transaction.

          Section 17.06 Provisions Relating to Collateral. (a) The Collateral
under the Pledge Agreement shall secure the Obligations and shall consist of the
following, other than such of the following as is released from the Lien of the
Pledge Agreement pursuant to Sections 17.06(b) through 17.06(g):

               (1) the Kaiser Common Shares deposited with the Collateral Agent
          in accordance with the requirements of Section 17.05(a);

               (2) all other Exchange Property for which the Exchangeable
          Securities may at any time or from time to time be exchangeable
          pursuant to the terms of this Indenture; and

               (3) all dividends, cash, instruments and other property and
          proceeds from time to time received, receivable or otherwise
          distributed in respect of or in exchange for any of the foregoing.

                                       98
<PAGE>
 
          (b) Unless an Event of Default has occurred and is continuing, the
Company shall be entitled to receive (or to receive from the Collateral Agent,
if theretofore delivered to the Collateral Agent) and retain, free of the Lien
of the Pledge Agreement, (1) all cash dividends and cash distributions paid on
the Kaiser Common Shares or other securities included in the Collateral, other
than Extraordinary Cash Distributions, (2) all interest payments on any debt
securities or other property included in the Collateral and (3) any net income
or gain on any investment of cash made by the Collateral Agent pursuant to the
Pledge Agreement (such amounts in clauses (1)-(3), collectively, "Excluded
Items").  During the continuance of an Event of Default, all rights of the
Company to receive and retain Excluded Items shall cease, and the Collateral
Agent shall thereupon have the sole right to receive any Excluded Items during
the continuance of such Event of Default; provided, however, that no Excluded
Items shall become part of the Exchange Property.  All Excluded Items retained
by the Collateral Agent shall be deposited in a collateral default account
established by the Collateral Agent for such purpose.  At such time, if any, as
all Events of Default shall have been cured or waived and no Event of Default
shall be continuing, the right of the Company to receive and retain any and all
Excluded Items shall be reinstated, and the Collateral Agent shall deliver to
the Company all Excluded Items held by it, upon delivery by the Company of an
Officers' Certificate stating that no Event of Default has occurred and is
continuing.

          (c) Any Collateral which constitutes Exchange Property that is
delivered by the Collateral Agent in exchange for Exchangeable Securities
surrendered for exchange shall, upon such delivery, be released from the Lien of
the Pledge Agreement.

          (d) The Collateral Agent shall release Collateral to the Company if
the Company has exercised the Cash Payment Election with respect to any
Exchangeable Security surrendered for exchange.  In these circumstances, the
Company shall be entitled to receive, out of the Collateral and free of the Lien
of the Pledge Agreement, such Exchange Property as would have been delivered in
exchange for such Exchangeable Security upon the exchange thereof had the
Company not exercised the Cash Payment Election, less the amount of Exchange
Property actually delivered to such Holder upon such exchange.

          (e) The Collateral Agent shall release Collateral to the Company if
the Company has redeemed any Exchangeable Security or purchased any Exchangeable
Security pursuant to any change of control put applicable to the Exchangeable
Securities.  In these circumstances, the Company shall be entitled to receive,
out of the Collateral and free of the Lien of the Pledge Agreement, such
Exchange Property as would have been deliverable upon the exchange of the
Exchangeable Securities redeemed or purchased by the Company pursuant to any
change of control put applicable to Exchangeable Securities.

                                       99
<PAGE>
 
          (f) In the case of the release of Collateral pursuant to Section
17.06(d) or 17.06(e) of this Indenture, the Collateral Agent shall promptly
deliver the requested Collateral upon receipt of (i) a written request from the
Company therefor, (ii) an Officers' Certificate stating that the release of the
requested Collateral is permitted by the provisions of Section 17.06(d) or
17.06(e), as the case may be, (iii) any instructions reasonably requested by the
Collateral Agent in connection with the delivery of Collateral to the Company
and (iv) any Exchangeable Securities that have been redeemed or purchased by the
Company pursuant to any change in control put and not theretofore delivered to
the Trustee for cancellation. The Collateral Agent shall deliver to the Trustee
for cancellation all Exchangeable Securities received by it pursuant to clause
(iv) of the preceding sentence.

          (g) Unless an Event of Default shall have occurred and is continuing,
the Company shall be entitled at any time and from time to time, out of the
Collateral, to such property as shall be in excess of the Exchange Property
which would be required for the exchange of all Exchangeable Securities then
outstanding for Exchange Property on the basis of the terms and provisions of
this Indenture (assuming no exercise by the Company of the Cash Payment
Election), and such excess shall, upon delivery of the Officers' Certificate
described in the following sentence, be released to the Company, free of the
Lien of the Pledge Agreement, upon demand.  Upon demanding any release of
Collateral pursuant to this Section 17.06(g), the Company shall, (1) deliver to
the Collateral Agent and the Trustee an Officers' Certificate that shall (A)
identify the principal amount of Exchangeable Securities then outstanding and
the Exchange Property required for delivery to the Holders thereof upon
exchange, (B) state that the release of such Collateral as so requested is
permitted by the provisions of this Section 17.06(g), and (C) state that the
Collateral to be released would not be deliverable upon exchange of all
Exchangeable Securities then outstanding (assuming no exercise by the Company of
the Cash Payment Election) and (2) provide any instructions reasonably requested
by the Collateral Agent or the Trustee in connection with the requested release
of Collateral.  Upon receipt of such Officers' Certificate from the Company, the
Collateral Agent shall, as promptly as possible, release to the Company the
Collateral requested to be released as specified in such Officers' Certificate.

          (h) Unless otherwise exempted therefrom by order of the Commission,
the Company shall comply with (i) Section 314(b) of the Trust Indenture Act
relating to Opinions of Counsel regarding the Lien of the Pledge Agreement and
(ii) Section 314(c) and 314(d) of the Trust Indenture Act, relating to the
release of Collateral from the Lien of the Pledge Agreement, Officers'
Certificates or other documents regarding fair value of the Collateral to be
released from the Lien of the Pledge Agreement, and Officers' Certificates and
Opinions of Counsel relating to the satisfaction of conditions precedent to the

                                      100
<PAGE>
 
release of Collateral from the Lien of the Pledge Agreement, to the extent any
of the foregoing provisions are applicable.  Any certificate or opinion required
by Section 314(d) of the Trust Indenture Act may be executed and delivered by an
Officer of the Company to the extent permitted by Section 314(d) of the Trust
Indenture Act.

          Section 17.07  Company To Give Notice of Certain Events.  If at any
time:

          (a) Kaiser or any other issuer of Exchange Property shall declare a
dividend or any other distribution (other than a cash dividend or other cash
distribution that is not an Extraordinary Cash Distribution) on Kaiser Common
Shares or other Exchange Property that constitutes capital stock;

          (b) Kaiser or any other issuer of Exchange Property shall authorize
the granting of subscription rights, options, warrants or other similar rights
to holders of Kaiser Common Shares or other Exchange Property, as the case may
be;

          (c) there shall occur any reclassification of Kaiser Common Stock
(other than a subdivision or combination of outstanding shares of Kaiser Common
Stock), or any recapitalization or restructuring of Kaiser which affects
Exchange Property, or any consolidation or merger to which Kaiser is a party and
for which approval of any stockholders of Kaiser is required, or the sale or
transfer of all or substantially all of the assets of Kaiser; or

          (d) there shall occur the voluntary or involuntary dissolution,
liquidation or winding up of Kaiser;

then the Company shall as promptly as practicable cause to be filed at each
office or agency maintained pursuant to this Indenture, and cause to be mailed
to the Holders of Exchangeable Securities at their last addresses as they shall
appear upon the Security Register, a notice stating (i) the date, if known by
the Company, on which a record is to be taken for the purpose of such dividend,
distribution or grant of rights, or, if a record is not to be taken, the date as
of which the holders of Kaiser Common Stock or other Exchange Property of record
to be entitled to such dividend or distribution or grant of rights are to be
determined, or (ii) the date, if known by the Company, on which such
reclassification, recapitalization, restructuring, merger, consolidation, sale,
transfer, dissolution, liquidation or winding up is expected to become
effective, and the date as of which it is expected that holders of Kaiser Common
Stock of record shall be entitled to exchange their shares of Kaiser Common
Stock for securities or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding up.

          Section 17.08  Merger of Kaiser.  (a)  In case of any consolidation or
merger of Kaiser with or into any other Person, or a binding share exchange,
which results in Kaiser Common Shares, as constituted prior to the consummation
of such transaction, being converted into other securities and/or property
(including cash), or in case of any sale or transfer of all or substantially all
of the assets of Kaiser (if, in connection with such sale or transfer, holders
of Kaiser Common Shares receive other securities and/or property, including
cash, in exchange for their Kaiser Common Shares), the Company shall execute and
deliver to the Trustee a supplemental indenture satisfactory in form to the
Trustee, and to the Collateral Agent a supplement to the Pledge Agreement
satisfactory in form to the Collateral Agent, each providing that the Holder of
each Exchangeable Security then outstanding shall have the right thereafter
(subject to Section 17.10 hereof) to exchange such Exchangeable Security (i) for
the kind and amount of securities and other property receivable upon such
consolidation, merger, binding share exchange, sale or transfer by a holder of
the number of Kaiser Common Shares for which such Exchangeable Security was
exchangeable immediately prior to such consolidation, merger, binding share
exchange, sale or transfer, had such holder of Kaiser Common Shares failed to
exercise any rights of election as to the kind or amount of securities or other
property receivable upon such consolidation, merger, binding share exchange,
sale or transfer, and (ii) such other Exchange Property for which such
Exchangeable Security was exchangeable immediately prior to such consolidation,
merger, binding share exchange, sale or transfer.  Such supplemental indenture
and supplement to the Pledge Agreement shall provide for adjustments, and rights
to receive and retain dividends or their equivalents, which shall be as nearly
equivalent as may be practicable to the adjustments, and rights to receive and
retain dividends or their equivalents, provided for in this Article Seventeen
and in the Pledge Agreement.  The above provisions of this Section 17.08 shall
similarly apply to any successive consolidation, merger, binding share exchange,
sale or transfer.

          (b) Notice of such supplemental indenture shall be filed with the
Collateral Agent and mailed (in the manner provided in Section 16.03) by or on
behalf of the Company as promptly as practicable to the Holders of Exchangeable
Securities at their last addresses as they shall appear on the Security
Register.

          (c) The Trustee shall not be under any responsibility to determine the
correctness of any provisions contained in any such supplemental indenture
relating either to the kind or amount of shares of stock or securities or
property or cash receivable by the Holders of Exchangeable Securities upon the
exchange of their Exchangeable Securities as herein provided after any such
consolidation, merger, binding share exchange, sale or transfer or to any
adjustment to be made with respect thereto.

          Section 17.09  Certain Tender of Exchange Offers for Exchange
Property.  (a)  In the event of a tender offer or exchange offer for any class
of securities included within the Exchange Property (an "Offer"), (i) if the
Company owns securities of such class which are not Exchange Property, the
Company will cause the Collateral Agent to tender such securities of such class
in the same proportion that the Company tenders its securities of such class
which are not Exchange Property, and (ii) if the only securities of such class
which the Company owns are Exchange Property, the Company may, at its option,
elect to cause the Collateral Agent to tender all or any portion or none of such
securities of such class, provided, however, that the Company may not cause the
Collateral Agent to tender any securities of any class into any Offer if (i) to
the knowledge of the Company, during the six months prior to such tender, the
Company and its Affiliates have sold to the offeror (or any Affiliate of the
offeror) in such Offer an aggregate amount of securities of such class, in any
one transaction or series of related transactions, which equals or exceeds, (A)
in the case of Kaiser Common Shares, 5,000,000 Kaiser Common Shares, as adjusted
to reflect stock splits, combinations and recapitalizations, or, (B) in the case
of other securities, 5% of the outstanding amount of securities of such class,
and the consideration offered in such Offer is lower per share or other unit of
securities of such class than the consideration per share or other unit of
securities of such class received by the Company or any of its Affiliates for
any sale (during the six months prior to such tender) of securities of such
class to the offeror (or any of its Affiliates) in such Offer, (ii) the Market
Value of the securities of such class that constitute Exchange Property at the
time of such tender exceeds $10 million and (iii) a majority of the securities
of such class held by Persons other than the Company or any Affiliate of the
Company have not been tendered (and not withdrawn) pursuant to such Offer as of
immediately prior to the Expiration Time.  Notwithstanding any other provision
of this Section 17.09(a), (i) in the case of a tender offer or exchange offer
made by the Company or any Affiliate of the Company, the Company will not cause
the Collateral Agent to tender any such securities included within the Exchange
Property unless a majority of such securities that are held by Persons other
than the Company or any Affiliate of the Company have been tendered and not
withdrawn pursuant to such tender or exchange offer as of immediately prior to
the Expiration Time, and (ii) the Collateral Agent shall not, prior to the close
of business on the date one Business Day preceding the date of any tender by the
Company (such preceding Business Day being hereinafter referred to as the
"Suspension Date"), tender shares or other units, as the case may be, of
Exchange Property required for exchange of Exchangeable Securities duly
surrendered for exchange pursuant to this Article Seventeen.

          (b) Upon receipt by the Company of written notice setting forth that
an Offer has commenced, it shall within three Business Days mail or cause to be
mailed (in the manner provided

                                      103
<PAGE>
 
in Section 16.03) notice to Holders of the Exchangeable Securities of the
existence of such an Offer, the right, if applicable, of the Company to cause
the tender of Exchange Property in response to such Offer in accordance with
this Section 17.09, the limitations contained in this Section 17.09 with respect
to the right of the Holders of the Exchangeable Securities to exchange pursuant
to this Article Seventeen after the Suspension Date, and the kind and amount of
Exchange Property apportioned thereto to be received in exchange for an
Exchangeable Security.  Such notice shall not be required to contain any
description of the applicable Offer other than the name of the tender offeror or
its agent and such offeror's or agent's address where information concerning
such Offer may be obtained.  If the Company shall deliver a Notice of Tender (as
defined in subparagraph (c) below) or a Notice of Withdrawal (as defined in the
subparagraph (d) below), it shall cause notice of the same to be published
promptly, at least once on each of two different Business Days in a newspaper of
national circulation or, in lieu of such publication, shall mail or cause to be
mailed to each Holder of Exchangeable Securities a copy of such Notice of Tender
or Notice of Withdrawal.

          (c) The Company may cause the Collateral Agent to tender Exchange
Property pursuant to subparagraph (a) above by delivering to the Collateral
Agent an Officers' Certificate instructing the Collateral Agent to tender the
applicable Exchange Property and stating that such tender is in accordance with
the terms and conditions of this Indenture (a "Notice of Tender"), together with
such evidence of authority and other documentation as may be required by the
terms of the Offer to enable the Collateral Agent to tender the Exchange
Property as required on behalf of the Company.

          (d) The Company may instruct the Collateral Agent by notice contained
in an Officers' Certificate after the Collateral Agent has tendered Exchange
Property pursuant to subparagraph (a) above to withdraw Exchange Property
tendered (a "Notice of Withdrawal") and upon receipt thereof the Collateral
Agent shall, if permitted by the terms of the Offer or applicable law, withdraw
the Exchange Property so tendered; provided, however, that if the Company owns
securities of the class subject to the Offer that are not Exchange Property,
then tendered Exchange Property may be withdrawn pursuant to the provisions of
this subparagraph (d) only at the same time and in the same proportion as the
Company withdraws such securities owned by the Company that are not Exchange
Property.

          (e) The proceeds of the sale of any Exchange Property pursuant to any
such tender or exchange offer will be held by the Collateral Agent as Exchange
Property for apportionment equally among the other Exchange Property, except
that the Company shall be entitled to any interest earned or dividends paid
thereon as and to the extent provided in the Pledge Agreement.  In the event
that for any reason all or any of the Exchange Property tendered

                                      104
<PAGE>
 
by the Collateral Agent is not purchased or exchanged pursuant to the Offer,
such remaining Exchange Property shall be redeposited with the Collateral Agent
and held pursuant to the Pledge Agreement and this Article Seventeen.

          (f) If, as a result of any Offer, all Kaiser Common Shares then
constituting Exchange Property shall have been sold or exchanged pursuant to
such Offer, the Company shall execute and deliver to the Trustee a supplemental
indenture satisfactory in form to the Trustee, and to the Collateral Agent a
supplement to the Pledge Agreement satisfactory in form to the Collateral Agent,
each providing that the Holder of each Exchangeable Security then outstanding
shall have the right thereafter (subject to Section 17.10 hereof) to exchange
such Exchangeable Security (i) for the kind and amount of securities and other
property receivable upon such tender or exchange by a holder of the number of
Kaiser Common Shares for which such Exchangeable Security was exchangeable
immediately prior to the Expiration Time of such Offer, and (ii) such other
Exchange Property for which such Exchangeable Security was exchangeable
immediately prior to the Expiration Time of such Offer.  Such supplemental
indenture and supplement to the Pledge Agreement shall provide for adjustments,
and rights to receive and retain dividends or their equivalents, which shall be
as nearly equivalent as may be practicable to the adjustments, and rights to
receive and retain dividends or their equivalents, provided for in this Article
Seventeen and in the Pledge Agreement.  Notice of such supplemental indenture
shall as soon as practicable be filed with the Collateral Agent and mailed (in
the manner provided in Section 16.03) by or on behalf of the Company to the
Holders of Exchangeable Securities at their last addresses as they shall appear
on the Security Register.  The Trustee shall not be under any responsibility to
determine the correctness of any provisions contained in any such supplemental
indenture relating either to the kind or amount of shares of stock or securities
or property or cash receivable by the Exchangeable Security Holders upon the
exchange of their Exchangeable Securities as herein provided after any such
tender or exchange or to any adjustment to be made with respect thereto.

          (g) After the close of business on a Suspension Date with respect to
an Offer as to which the Company has not withdrawn its Notice of Tender, the
Collateral Agent shall not accept any Exchangeable Securities for exchange and
the exchange privilege shall be suspended until such time as any proceeds
pursuant to such Offer have been deposited with the Collateral Agent and any
Exchange Property tendered by the Collateral Agent that is not purchased or
exchanged pursuant to such Offer has been redeposited (the "Completion Time").
In the event that any Exchangeable Security is surrendered for exchange during
such time as the exchange privilege is suspended pursuant to this Section 17.09,
the Collateral Agent shall not accept such Exchangeable Security for exchange
and shall not effect the exchange of such Exchangeable Security and shall so
notify the

                                      105
<PAGE>
 
Holder surrendering such Exchangeable Security and shall notify (using a form of
notice supplied by the Company) such Holder of the further provisions of this
subparagraph (g).  The Holder of such Exchangeable Security may direct in
writing, and the Collateral Agent shall comply with such written direction
received by it, that the Collateral Agent either (i) return such Exchangeable
Security and cancel the election to exchange such Exchangeable Security provided
that such direction is received by the Collateral Agent not later than the
Business Day preceding the Reinstatement Date (as defined below), or (ii) retain
the Exchangeable Security for exchange at such time and on such date (the
"Reinstatement Date" and, with respect to such exchange, the Exchange Date) as
of which the Company shall, in an Officers' Certificate (to be furnished as soon
as practicable after the Completion Time), state that such suspension of the
exchange privilege has ceased and the exchange privilege has been reinstated,
provided that the exchange is otherwise permitted at that time.

          (h) The above provisions of this Section 17.09 shall similarly apply
to any successive tender or exchange offer.

          Section 17.10 Cash Payment Election. (a) Notwithstanding any other
provisions in this Indenture or in the Pledge Agreement, in lieu of delivering
certificates representing Kaiser Common Shares or other Marketable Securities
included in the Exchange Property in exchange for Exchangeable Securities
surrendered in accordance with Section 17.02, the Company may elect to exercise
the Cash Payment Election as provided in this Section 17.10; provided, however,
that the Company may not elect to deliver cash pursuant to this Section 17.10 in
lieu of Exchange Property which does not consist of Kaiser Common Shares or
other Marketable Securities. To the extent that the Company shall have notified
the Collateral Agent pursuant to Section 17.02 that it will pay cash in lieu of
Kaiser Common Shares or other Marketable Securities in respect of any exchange,
the Company shall deliver or shall cause the Collateral Agent to deliver, no
later than the seventh Business Day following the Exchange Date (subject to
subparagraph (c) of Section 17.02), to the Holder surrendering such Exchangeable
Securities an amount in cash equal to the Market Value of the Kaiser Common
Shares or other Marketable Securities as to which the Cash Payment Election has
been exercised (determined as of the Exchange Date), plus any other Exchange
Property theretofore apportioned to such Kaiser Common Shares or other
Marketable Securities in accordance with Section 17.05 or Section 17.09. Prior
to so directing the Collateral Agent to make any such cash payment, the Company
shall deposit with the Collateral Agent the cash so payable in clearing house or
immediately available funds. After making such cash payment, the Company shall
be entitled to receive the Exchange Property as to which cash was so paid, as
provided in Section 17.06(d).

                                      106
<PAGE>
 
          (b) As used in this Article Seventeen, "Market Value" of any
Marketable Securities (including Kaiser Common Shares) as of any date means the
product of (i) the Market Price of such Marketable Securities as of such date
and (ii) the number of shares or other units of such Marketable Securities.
"Market Price" as of any date means, (i) in the case of Kaiser Common Shares or
other Marketable Securities, the average closing market price per share or other
unit (or average closing bid and asked prices, if closing prices are not
available) as reported by the primary national securities exchange on which such
security is listed (or, if such security is not listed on a national securities
exchange, as reported by Nasdaq) for the five consecutive trading days
immediately preceding such date (or if such date is not a Business Day, the
Business Day next preceding such date); provided, however, that, if any
adjustment of the Exchange Rate pursuant to Section 17.04(a) hereof is effective
as of any date during the period beginning on the first day of such five
consecutive trading days and ending on such date, the Market Price as determined
pursuant to the foregoing shall be adjusted, to the extent appropriate, to
reflect the event giving rise to such adjustment, or (ii) in the case of
Exchange Property other than Marketable Securities, the market value per unit of
such property on such date as determined by an investment banking firm selected
by the Collateral Agent.  As used in this Article Seventeen, "Marketable
Securities" means any security listed on the New York Stock Exchange or the
American Stock Exchange or for which quotations are reported on Nasdaq.

          Section 17.11  Obligations of Trustee and Collateral Agent.  Subject
to the provisions of Section 6.01, neither the Trustee nor the Collateral Agent
shall at any time be under any duty or responsibility to any Holder of
Exchangeable Securities to determine whether any facts exist which may require
any adjustment of the Exchange Rate, or with respect to the nature or extent of
any such adjustment when made, or with respect to the method employed, or herein
or in any supplemental indenture required to be employed, in making the same.
Neither the Trustee nor the Collateral Agent shall be accountable with respect
to the validity or value (or the kind or amount) of any Exchange Property which
may at any time be issued or delivered upon the exchange of any Exchangeable
Security or the market conditions existing at the time of sale of any Exchange
Property; and neither the Trustee nor the Collateral Agent makes any
representation with respect thereto.  Neither the Trustee nor the Collateral
Agent shall be responsible for any failure of the Company to transfer or deliver
any Exchange Property or certificates or other evidence thereof to the
Collateral Agent as provided herein or in any supplemental indenture or in the
Pledge Agreement or, subject to the provisions of Section 6.01 and the
obligations assumed under the Pledge Agreement, to comply with any of the
covenants of the Company contained in this Article Seventeen.

                                      107
<PAGE>
 
          Section 17.12  Limitation on Liens on Exchange Property.  The Company
covenants with respect to any Kaiser Common Shares and any other Exchange
Property apportioned thereto with respect to which it has granted a Lien
pursuant to the Pledge Agreement, that it will not, and will not permit any
Subsidiary to, directly or indirectly, create, incur, assume or permit to exist,
will defend such Kaiser Common Shares and any cash and other Exchange Property
apportioned thereto against, and will take such action as is necessary to
remove, any Lien or claim on or in respect of such Kaiser Common Shares and any
other Exchange Property apportioned thereto, except (i) the Liens created by the
Pledge Agreement, (ii) Liens for taxes, assessments or other governmental
charges or levies not yet due or payable under law or being contested in good
faith by appropriate proceedings, (iii) Liens arising by operation of law in the
ordinary course of business and with respect to amounts not overdue for a period
of more than 90 days or being contested in good faith by appropriate proceedings
and (iv) judgment Liens and other similar Liens arising in connection with court
proceedings; provided, however, that the execution or other enforcement thereof
is effectively stayed within 90 days following entry of judgment and the claims
secured thereby are being actively contested in good faith and by appropriate
proceedings.

          Section 17.13  Transfer Taxes.  The Company will pay any and all
documentation, stamp, transfer or similar taxes that may be payable in respect
of the transfer and delivery of Kaiser Common Shares (or other securities
included in the Exchange Property) pursuant hereto; provided, however, that the
Company shall not be required to pay any tax which may be payable in respect of
any transfer involved in the delivery, upon an exchange of Exchangeable
Securities, of Kaiser Common Shares (or other securities included in the
Exchange Property) in a name other than that in which the Exchangeable
Securities so exchanged were registered, and no such transfer shall be made
unless and until the Person requesting such transfer has paid to the Company or
the Collateral Agent the amount of any such tax, or has established to the
satisfaction of the Company and the Collateral Agent that such tax has been
paid; and provided, further, that the Company shall not be obligated to pay any
withholding taxes payable by Holders of Exchangeable Securities due to the
exchange of any Exchangeable Securities.

          Section 17.14  Cancellation of Exchangeable Securities.  All
Exchangeable Securities delivered for exchange shall be delivered by the
Collateral Agent to the Trustee and be cancelled by the Trustee.

          Section 17.15  Registration of Kaiser Common Stock and Other
Securities Held as Exchange Property.  (a)  The Company hereby covenants that at
any time that a Holder of Exchangeable Securities exchanges such Exchangeable
Securities for certificates representing Kaiser Common Shares and an effective

                                      108
<PAGE>
 
registration statement of Kaiser filed with the Commission (or related
qualification under applicable state blue sky or securities laws) would be
required in order for the Collateral Agent to deliver such Kaiser Common Shares
in the United States to a U.S. Person, the Company will ensure that an effective
registration statement of Kaiser is on file with the Commission covering the
delivery of such Kaiser Common Shares and any qualification under state blue sky
or securities laws required for such delivery is maintained.

          (b) If, pursuant to the transactions described in Sections 17.05,
17.08 and 17.09 hereof, Exchange Property includes securities which, in the
opinion of counsel for the Company, may not be delivered in exchange for
Exchangeable Securities without registration under the Securities Act, the
Company shall use its best efforts to cause such securities to be so registered
as promptly as practicable, except that, in the absence of such registration,
the Company may, at its option, sell such securities in a transaction on arm's-
length terms to a Person that is not an Affiliate of the Company and deliver
cash in lieu of such securities in the manner provided in Section 17.10 hereof
in lieu of such registration; provided, however, that the Company shall not sell
any securities of Kaiser or any of its subsidiaries pursuant to this sentence
without the consent of the Holders of not less than a majority in principal
amount of the Outstanding Exchangeable Securities.

to be granted hereby or to enable the Collateral Agent to exercise and enforce
its rights and remedies hereunder with respect to any Collateral.

          SECTION 4.  Representations and Warranties.  (a)  The Company hereby
represents and warrants for the benefit of the Collateral Agent on behalf of the

not contravene, or constitute a default under, any provision of the certificate

and its subsidiaries, taken as a whole, of any agreement, judgment, injunction,
order, decree or other instrument binding upon the Company, or result in the
creation or imposition of any Lien on any Collateral, other than the Lien
contemplated hereby.

                                       3

duly authorized and validly issued and are fully paid and non-assessable.

          (iii)  The Company is the record and beneficial owner of the Kaiser
Common Shares that constitute Collateral, free and clear of any Lien or claims
of any Person except for the security interest created by this Agreement.

          (iv)  The Company has full corporate power and authority to enter into
this Agreement and has the right to pledge and grant a security interest in the
Collateral as provided by this Agreement.

          (v)  This Agreement has been duly executed and delivered by the
Company and constitutes a legal, valid and binding obligation of the Company,
enforceable against the Company in accordance with its terms, except as the
enforceability thereof may be subject to (A) bankruptcy, insolvency,

laws now or hereafter in effect affecting creditors' rights generally and (B)
general principles of equity (regardless of whether enforceability is a

          (vi)  Upon delivery to the Collateral Agent of the Kaiser Common Stock
referred to in the first sentence of Section 2 hereof, the pledge of such Kaiser
Common Stock creates a valid and perfected first priority security interest in
such Kaiser Common Stock securing the payment of the Obligations for the benefit
of the Trustee, the Collateral Agent and the Holders, to the extent provided
herein.

          (b)  The Collateral Agent represents and warrants that (i) it has full
corporate power and authority to enter into and perform this Agreement and the
Indenture and (ii) this Agreement and the Indenture have been duly and validly

Street Bank and Trust Company, in its capacity

                                       4
<PAGE>
 
under this Agreement; provided, however, that if any Collateral shall at any
time not be DTC eligible securities or if the Collateral Agent determines in its
sole discretion that such Collateral shall no longer be registered in the name
of DTC or its nominee, the certificate or certificates representing such
Collateral shall be held by the Collateral Agent at a location in Boston,
Massachusetts, selected by the Collateral Agent and shall be registered in the
name of the Collateral Agent or its nominee (other than DTC or its nominee).
From time to time thereafter, the Company shall take such actions and shall
execute and deliver such certificates and other documents as the Collateral
Agent shall reasonably request in order to evidence that record ownership of the
Collateral shall be vested in the Collateral Agent or its nominee, and the
Company shall take such actions and shall execute and deliver such certificates
and other documents as the Collateral Agent shall reasonably request in
connection with the security interest granted pursuant to this Pledge Agreement.

          SECTION 6. Exchange. Subject to the terms and conditions of this
Agreement, the Exchangeable Securities and the Indenture, upon proper surrender
to the Collateral Agent of any Exchangeable Security (or any portion of the
principal amount thereof) for exchange by the Holder thereof in accordance with
the terms thereof and of the Indenture, the Collateral Agent shall (i) promptly
notify the Company of such surrender and (ii) following such surrender and
notification, promptly accept the same for exchange, and upon such acceptance
and within the applicable time periods set forth in Section 17.02(b) and/or
Section 17.10 of the Indenture (A) except to the extent provided in clause (F)
below, either (1) obtain from the transfer agent for the Kaiser Common Shares
and all other securities for which the Exchangeable Securities are then
exchangeable pursuant to the terms of the Indenture ("Exchange Securities") and
deliver or cause to be delivered to or on the order of the Holder of such
Exchangeable Security (or portion thereof), a certificate or certificates
representing such number of whole Exchange Securities, or (2) instruct DTC or,
if applicable, any other nominee in whose name the Exchange Securities are
registered, to transfer to such Holder's account (or the account of such
Holder's nominee) such number of whole Exchange Securities, as such Holder may
be entitled to receive in accordance with the terms of the Exchangeable Security
and of the Indenture; (B) except to the extent provided in clause (F) below,
deliver or cause to be delivered to or on the order of such Holder a check in
payment of any cash adjustment in lieu of fractional shares or other units, as
the case may be, computed in accordance with the Indenture and such additional
cash as may have been apportioned under the Indenture to the Exchange Property
which the Holder of such Exchangeable Security (or portion thereof) shall be
entitled to receive in accordance with the terms thereof and of the Indenture;
(C) except to the extent provided in clause (F) below, deliver or cause to be
delivered to or on the order of such Holder any other certificates or

                                       5
<PAGE>
 
instruments or other property constituting or evidencing ownership of the
Exchange Property as such Holder may be entitled to receive in accordance with
the terms of the Exchangeable Security and of the Indenture; (D) deliver for
cancellation to the Trustee the Exchangeable Security so exchanged; (E) if only
a portion of said Exchangeable Security is exchanged and if the Exchangeable
Securities are represented by certificates, obtain from the Trustee and deliver
to or on the order of the Holder of the Exchangeable Security surrendered for
exchange a new Exchangeable Security or Exchangeable Securities for the
principal amount at maturity thereof not exchanged; (F) to the extent the
Company exercises its Cash Payment Election in lieu, in whole or in part, of
delivery of Kaiser Common Stock or other Marketable Securities included in the
Exchange Property pursuant to Section 17.10 of the Indenture and if sufficient
funds are first deposited with the Collateral Agent by the Company, the
Collateral Agent shall, to such extent, in lieu of the actions set forth in
clauses (A) through (C) above, pay to the Holder of such  Exchangeable Security
so surrendered an amount in cash as provided by Section  17.10 of the Indenture;
and (G) if the Company exercises its Cash Payment Election in lieu, in whole or
in part, of delivery of Kaiser Common Stock or Marketable Securities included in
the Exchange Property pursuant to Section 17.10 of the Indenture but cash is not
delivered in accordance with the Indenture, the Collateral Agent shall take the
actions set forth in clauses (A) through (C) above.

          The Company will, upon request, promptly notify the Collateral Agent
in an Officers' Certificate, setting forth the Company's calculations in
reasonable detail, of the Market Value or Market Price as of the relevant dates
for the purpose of computing cash adjustments to be paid upon exchanges in lieu
of fractional shares or other units, as the case may be, or for any other
purpose the Collateral Agent deems appropriate.

          SECTION 7.  Voting Rights; Dividends; Etc.

          (a) So long as no Event of Default shall have occurred and be
continuing and until written notice from the Collateral Agent to the Company,
given during the continuance of an Event of Default (other than an Event of
Default under Section 5.01(6) or 5.01(7) of the Indenture relating only to the
Company, in which case no notice shall be required), that the Collateral Agent
intends to exercise its rights to vote the Collateral, the Company shall be
entitled to exercise any and all voting and other corporate rights pertaining to
the Kaiser Common Shares or any other voting securities constituting Collateral
for any purpose not inconsistent with the terms of the Indenture, this Agreement
or the Exchangeable Securities; provided, however, that no vote shall be cast or
consent, waiver or ratification given or action taken that would be inconsistent
with or violate any provision of the Indenture, this Agreement or the
Exchangeable Securities.  If an Event of Default has occurred and is continuing,
upon written notice from the Collateral Agent to the

                                       6
<PAGE>
 
Company that it has determined that it will exercise such rights, all rights of
the Company to exercise the voting and other consensual corporate rights which
it would otherwise be entitled to exercise shall cease and all such rights shall
become vested in the Collateral Agent, which shall thereupon have the sole right
to exercise such voting and other consensual corporate rights during the
continuance of such Event of Default.  The Collateral Agent shall have no duty
to the Company to exercise any of the aforesaid voting or other consensual
rights, and shall not be responsible for any failure to do so or delay in so
doing.  When any and all Events of Default have been cured or waived, such
voting and consensual corporate rights shall revert to the Company.

          (b) Unless an Event of Default has occurred and is continuing, the
Company shall be entitled to receive (or to receive from the Collateral Agent if
theretofore delivered to the Collateral Agent) and retain, free of the Lien of
this Pledge Agreement, (1) all cash dividends and cash distributions paid on the
Kaiser Common Shares or other securities included in the Collateral, other than
Extraordinary Cash Distributions, (2) all interest payments on any debt
securities or other property included in the Collateral and (3) any net income
or gain on any investment of cash made by the Collateral Agent pursuant to this
Pledge Agreement (such amounts in clauses (1) through (3), collectively,
"Excluded Items").  During the continuance of an Event of Default, all rights of
the Company to receive and retain Excluded Items shall cease, and the Collateral
Agent shall thereupon have the sole right to receive any Excluded Items during
the continuance of such Event of Default; provided, however, that no Excluded
Items shall become part of the Exchange Property.  All Excluded Items retained
by the Collateral Agent shall be deposited in a collateral default account
established by the Collateral Agent for such purpose.  At such time, if any, as
all Events of Default shall have been cured or waived and no Event of Default
shall be continuing, the right of the Company to receive and retain any and all
Excluded Items shall be reinstated, and the Collateral Agent shall deliver to
the Company all Excluded Items then held by it, upon delivery by the Company of
an Officers' Certificate stating that no Event of Default has occurred and is
continuing.

          (c) In order to permit the Company to exercise the voting and other
consensual rights which it may be entitled to exercise pursuant to Section 7(a),
and to receive all Excluded Items which it may be entitled to receive under
Section 7(b), the Collateral Agent shall, upon written notice from the Company,
from time to time execute and deliver to the Company such instruments as the
Company may reasonably request.

          SECTION 8.  Investments of Cash.  All cash held by the Collateral
Agent pursuant to this Agreement (whether or not such cash constitutes Exchange
Property) shall be invested by the Collateral Agent from time to time in
accordance with the written

                                       7 
<PAGE>
 
instructions of the Company in Cash Equivalents with maturity dates of twelve
months or less.  Any interest or gain on such investments shall be for the sole
account of the Company and shall be paid over to the Company by the Collateral
Agent as provided in Section 7(b).  Any loss on such investments shall be for
the account of the Company and the Company shall, on demand, reimburse the
Collateral Agent for any such loss.  The Company shall have the option either to
furnish to the Collateral Agent all money payable to Holders upon any exchange
of Exchangeable Securities or to require the Collateral Agent to sell Cash
Equivalents in an amount necessary to permit the Collateral Agent to make such
payments.

          SECTION 9.  Release of Collateral.

          (a) The provisions of Sections 17.05(b), 17.05(c), 17.06(b) through
17.06(h) and 17.09 of the Indenture are incorporated herein by reference and
shall be a part hereof as though fully set forth herein.

          (b) Any Collateral which is delivered by the Collateral Agent pursuant
to the provisions referred to in Section 9(a), including, without limitation,
(i) Collateral delivered pursuant to Section 6 or Section 7(b) of this Pledge
Agreement or (ii) as a pro rata distribution to Holders of Exchangeable
Securities pursuant to Section 17.05(c) of the Indenture shall, in each case, be
released from the Lien of this Pledge Agreement upon such delivery.

          SECTION 10.  Merger or Consolidation of the Company. If the
Company is discharged from its obligations under the Indenture by the operation
of Article Ten thereof, the Company shall also be discharged from all its
obligations under this Agreement.  The Company shall not allow any Person to
assume the obligations of the Company under the Indenture unless such person
also expressly assumes, by an agreement supplemental hereto, executed and
delivered to the Collateral Agent, all the obligations of the Company under this
Agreement.

          SECTION 11.  Power of Attorney.  The Company hereby appoints the
Collateral Agent as its attorney-in-fact, with power of substitution and with
full authority in its place and stead and in its name or the Collateral Agent's
own name, from time to time during the continuance of an Event of Default, in
the Collateral Agent's discretion, subject to the provisions of this Agreement,
to take any action and to execute any instrument which the Collateral Agent may
deem necessary or advisable in order to accomplish the purposes of this
Agreement, including to receive, endorse and collect all instruments made
payable to it representing any dividend, interest payment or other distribution
in respect of the Collateral or any part thereof and to give full discharge for
the same.  This power, being coupled with an interest, is irrevocable.

                                       8
<PAGE>
 
          SECTION 12.  Collateral Agent May Perform.  If the Company fails to
perform in any material respect any agreement contained herein, the Collateral
Agent may itself perform, or cause the performance of, such agreement, and the
reasonable expenses of the Collateral Agent incurred in connection therewith
shall be payable by the Company under Section 16 hereof.

          SECTION 13.  No Assumption of Duties; Reasonable Care.  The rights and
powers granted to the Collateral Agent hereunder are being granted in order to
preserve and protect the Collateral Agent's security interest in and to the
Collateral granted hereby and shall not be interpreted to, and shall not, impose
any duties on the Collateral Agent to exercise any such powers or rights.  The
Collateral Agent shall be deemed to have exercised reasonable care in the
custody and preservation of the Collateral in its possession if the Collateral
is accorded treatment substantially equal to that which the Collateral Agent
accords its own property, it being understood that the Collateral Agent shall
not have any responsibility for (i) ascertaining or taking action with respect
to calls, conversions, exchanges, maturities, tenders or other matters relative
to any Collateral, whether or not the Collateral Agent has or is deemed to have
knowledge of such matters, except upon express instructions pursuant to the
Indenture or this Agreement or (ii) taking any necessary steps to preserve
rights against any parties with respect to any Collateral.

          SECTION 14.  Subsequent Changes Affecting Collateral.  The Company
represents to the Collateral Agent that the Company has made its own
arrangements for keeping informed of changes or potential changes affecting the
Collateral (including, but not limited to, rights to convert, rights to
subscribe, payment of dividends, payments of interest and/or principal,
reorganization or other exchanges, tender offers and voting rights), and the
Company agrees that the Collateral Agent shall have no responsibility or
liability for informing the Company of any such changes or potential changes or,
except upon express instructions pursuant to the Indenture or this Agreement,
for taking any action or omitting to take any action with respect thereto.

          SECTION 15.  Remedies Upon Default.
          (a)  If any Notice of Acceleration shall have been delivered to the
Company and shall not have been rescinded, the Collateral Agent shall have, in
addition to all other rights given by law or by this Agreement or the Indenture,
but subject to the provisions of Section 17.02(f) of the Indenture, all of the
rights and remedies with respect to the Collateral of a secured party under the
Uniform Commercial Code as in effect in the State of New York at that time.  In
addition, the Collateral Agent may sell or cause the Collateral to be sold at
any broker's board or at public or private sale, in one or more sales or lots,
at such price or prices as the Collateral Agent may deem best, for cash or on
credit or for future delivery, without assumption

                                       9
<PAGE>
 
of any credit risk.  The purchaser of any or all Collateral so sold shall
thereafter hold the same absolutely, free from any claim, encumbrance or right
of any kind whatsoever.  Unless any of the Collateral threatens to decline
rapidly in value or is or becomes of a type sold on a recognized market, the
Collateral Agent will give the Company reasonable notice of the time and place
of any public sale thereof, or of the time after which any private sale or other
intended disposition is to be made.  Any sale of the Collateral conducted in
conformity with reasonable commercial practices of banks, insurance companies,
commercial finance companies, or other financial institutions disposing of
property similar to the Collateral shall be deemed to be commercially
reasonable.  Any requirements of reasonable notice shall be met if such notice
is mailed to the Company as provided below in Section 18.1, at least ten days
before the time of the sale or disposition.  Any other requirement of notice,
demand or advertisement for sale is, to the extent permitted by law, waived.
The Collateral Agent or any Holder of Exchangeable Securities may, in its own
name or in the name of a designee or nominee, buy any of the Collateral at any
public sale and, if permitted by applicable law, at any private sale.

          The Company recognizes that, by reason of certain prohibitions
contained in the Securities Act and applicable state securities laws, the
Collateral Agent may be compelled, with respect to any sale of all or any part
of the Collateral, to limit purchasers to those who will agree, among other
things, to acquire such securities for their own account, for investment and not
with a view to the distribution or resale thereof.  The Company acknowledges and
agrees that any such sale may result in prices and other terms less favorable to
the seller than if such sale were a public sale without such restrictions and,
notwithstanding such circumstances, agrees that any such sale of any Collateral
shall be deemed to have been made in a commercially reasonable manner.  The
Collateral Agent shall be under no obligation to delay the sale of any
securities included in the Collateral for the period of time necessary to permit
the registration of such securities for public sale under the Securities Act or
under applicable state securities laws.

          If a Notice of Acceleration has been delivered and is at the time in
effect, unless in the written opinion of counsel to the Company (Kramer, Levin,
Naftalis, Nessen, Kamin & Frankel or other counsel reasonably satisfactory to
the Collateral Agent) addressed and delivered to the Collateral Agent,
registration is not required for the unrestricted sale of Kaiser Common Shares
by the Collateral Agent, the Collateral Agent may, upon written notice, require
the Company to use its best efforts to cause to be registered as soon as
possible pursuant to the Securities Act and relevant state securities laws the
Kaiser Common Shares included in the Collateral, and to keep such registration
effective for at least 180 consecutive days, and to enter into customary
arrangements with the Trustee and the Collateral Agent concerning
indemnification and reimbursement of expenses.

                                      10
<PAGE>
 
          SECTION 16.  Fees and Expenses.  The Company will upon demand pay to
the Collateral Agent the amount of any and all reasonable fees and expenses
(including, without limitation, the reasonable fees and disbursements of its
counsel, of any investment banking firm, business broker or other selling agent
and of any other experts and agents not regularly in its employ retained by the
Collateral Agent) that the Collateral Agent may incur (other than any such fees
and expenses as may arise from the gross negligence or willful misconduct of the
Collateral Agent) in connection with (i) the custody or preservation of, or the
sale of, collection from, or other realization upon, any of the Collateral or
(ii) the exercise or enforcement of any of the rights of the Collateral Agent
hereunder.

          SECTION 17.  Application of Proceeds.  The proceeds of any sale of, or
other realization upon, all or any part of the Collateral, and, subject to the
provisions of Section 17.02(f) of the Indenture, any cash held as Collateral
while a Notice of Acceleration is in effect, shall be paid over to the Trustee
