substantially similar tenor signed by such Holders in person, or by an agent
duly appointed in writing; and, except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments are
delivered to the Trustee and, where it is hereby expressly required, to the
Company. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the Holders
signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Indenture and (subject to Section 601) conclusive 


   15

Section.

          (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such

law to take acknowledgements of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such

Company in reliance thereon, whether or not notation of such action is made upon
such Security.

          (e) The Company may, in the circumstance permitted by the Trust
Indenture Act, set any day as the record date for the purpose of determining the
Holders of Outstanding Securities of any series entitled to give or take any
request, demand, authorization, direction, notice, consent, waiver, or other
action provided or permitted by this Indenture to be given or taken by Holders
of Securities of such series. With regard to any record date set pursuant to
this paragraph, the Holders of Outstanding Securities of the relevant series on
such record date (or their duly appointed agents), and only such persons, shall
be entitled to give or take the relevant action, whether or not such Holders
remain Holders after such record date. With regard to any action that may be
given or taken hereunder only by Holders of a requisite principal amount of
Outstanding Securities of any series (or their duly appointed agents) and for
which a record date is set pursuant to this paragraph, the Company may, at its
option, set an expiration date after which no such action purported to be given
or taken by any Holder shall be effective hereunder unless given or taken on or
prior to such expiration date by Holders of the requisite principal amount of
Outstanding Securities of such series on such record date (or their duly
appointed agents). On or prior to any expiration date set pursuant to this
paragraph, the Company may, on one or more occasions at its option, extend such
date to any later date. Nothing in this paragraph shall prevent any Holder (or
any duly appointed agent thereof) from giving or taking, after any such
expiration date, any action identical to, or, at any time, contrary to or
different from, the action or purported action to which such expiration date
relates, in which event the Company may set a record date in respect thereof
pursuant to this paragraph. Nothing in this paragraph shall be construed to
render ineffective any action taken at any time by the Holders (or their duly
appointed agents) of the requisite principal amount of Outstanding Securities of
the relevant series on the date such action is so taken. Notwithstanding the
foregoing or the Trust Indenture Act, the Company shall not set a record date
for, and provisions of this 


   16


paragraph shall not apply with respect to, any notice, declaration or direction
referred to in the next paragraph.

      Upon receipt by the Trustee from any Holder of Securities of a particular
series of (i) any notice of default or breach referred to in Section 501(4) with
respect to Securities of such series, if such default or breach has occurred and
is continuing and the Trustee shall not have given such notice to the Company,
(ii) any declaration of acceleration referred to in Section 502, if an Event of
Default with respect to Securities of such series has occurred and is continuing
and the Trustee shall not have given such a declaration to the Company, or (iii)
any direction referred to in Section 512 with respect to Securities of such
series, if the Trustee shall not have taken the action specified in such
direction, then a record date shall automatically and without any action by the
Company or the Trustee be set for determining the Holders of Outstanding
Securities of such series entitled to join in such notice, declaration or
direction, which record date shall be the close of business on the tenth day
following the day on which the Trustee receives such notice, declaration or
direction. Promptly after such receipt by the Trustee, and in any case not later
than the fifth day thereafter, the Trustee shall notify the Company and the
Holders of Outstanding Series of such series of any such record date so fixed.
The holders of Outstanding Securities of such series on such record date (or
their duly appointed agents), and only such Persons, shall be entitled to join
in such notice, declaration or direction, whether or not such Holders remain
Holders after such record date; provided that unless such notice, declaration or
direction shall have become effective by virtue of Holders of the requisite
principal amount of Outstanding Securities of such series on such record date
(or their duly appointed agents) having joined therein on or prior to the 90th
day after such record date, such notice, declaration or direction shall
automatically and without any action by any Person be cancelled and of no
further effect. Nothing in this paragraph shall be construed to prevent a Holder
(or a duly appointed agent thereof) from giving, before or after the expiration
of such 90-day period, a notice, declaration or direction contrary to or
different from, or, after the expiration of such period, identical to, the
notice, declaration or direction to which such record date relates, in which
event a new record date in respect thereof shall be set pursuant to this
paragraph. Nothing in this paragraph shall be construed to render ineffective
any notice, declaration or direction of the type referred to in this paragraph
given at any time to the Trustee and the Company by Holders (or their duly
appointed agents) of the requisite principal amount of Outstanding Securities of
the relevant series on the date such notice, declaration or direction is so
given.

      Without limiting the foregoing, a Holder entitled hereunder to give or
take any action hereunder with regard to any particular Security may do so with
regard to all or any part of the principal amount of such Security or by one or
more duly appointed agents each of which may do so pursuant to such appointment
with regard to all or any different part of such principal amount.

SECTION 105.   Notices to Trustee and Company.

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


   17



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

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

SECTION 106.   Notice to Holders; Waiver.

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

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

SECTION 107.   Conflict with Trust Indenture Act.

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

   22



the maturity thereof ("Original Issue Discount Securities") Special United
States federal income tax, accounting and other considerations applicable to

Prospectus Supplement.

      All Securities of any one series shall be substantially identical except
as to denomination and except as may otherwise be provided in or pursuant to the
Board Resolution referred to above and (subject to Section 303) set forth, or
determined in the manner provided, in the Officers' Certificate referred to
above or in any such indenture supplemental hereto.

      If any of the terms of the series are established by action taken pursuant
to a Board Resolution, a copy of an appropriate record of such action shall be
certified by the Secretary or an Assistance Secretary of the Company and
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series.

      The Securities shall be redeemable as provided in Article Eleven.

      The Securities shall be convertible as provided in Article Twelve.

      The Securities shall be issuable only in registered form without coupons

Securities of any series, the Securities of such series shall be issuable in
denominations of $1,000 and any integral multiple thereof.

SECTION 303.   Execution, Authentication, Delivery and Dating.

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

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

      At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities executed by the Company to the
Trustee for authentication, together with a Company Order for the authentication
and delivery of such Securities.

      If the form or terms of the Securities of the series have been established
in or pursuant to one or more Board Resolutions as permitted by Sections 201 and
301, in authenticating such Securities, and accepting the additional
responsibilities under 


   23



this Indenture in relation to such Securities, the Trustee shall be entitled to
receive, and (subject to Section 601) shall be fully protected in relying upon,
an Opinion of Counsel stating,

          (1) if the form of such Securities has been established by or pursuant
to Board Resolution as permitted by Section 201, that such form has been
established in conformity with the provisions of this Indenture;

          (2) if the terms of such Securities have been established by or
pursuant to Board Resolution as permitted by Section 301, that such terms have
been established in conformity with the provisions of this Indenture; and

          (3) that such Securities, when authenticated and delivered by the
Trustee and issued by the Company in the manner and subject to any conditions
specified in such Opinion of Counsel, will constitute valid and legally binding
obligations of the Company enforceable in accordance with their terms, subject
to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
similar laws of general applicability relating to or affecting creditors' rights
and to general equity principles.

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonable acceptable to the Trustee.

      Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the time
of authentication of each Security of such series if such documents are
delivered at or prior to the authentication upon original issuance of the first
Security of such series to be issued.

      Each Security shall be dated the date of its authentication.

      No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder and is entitled to the
benefits of this Indenture.

SECTION 304.   Temporary Securities.

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


   24



      If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay. After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at any office
or agency of the Company designated pursuant to Section 1002, without charge to
the Holder. Upon surrender for cancellation of any one or more temporary
Securities the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of definitive Securities of
authorized denominations. Until so exchanged the temporary Securities shall in
all respects be entitled to the same benefits under this Indenture as definitive
Securities of such series and tenor.

SECTION 305.   Registration, Registration of Transfer and Exchange.

      The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency designated pursuant to Section 1002 being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is hereby
appointed "Security Registrar" for the purpose of registering Securities and
transfers of Securities as herein provided. Upon surrender for registration of
transfer of any Security at an office or agency of the Company designated
pursuant to Section 1002 for such purpose, the Company shall execute, and the
Trustee shall authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Securities of any authorized denominations and
of a like aggregate principal amount. At the option of the Holder, Securities
may be exchanged for other Securities of any authorized denominations and of a
like aggregate principal amount, upon surrender of the Securities to be
exchanged at such office or agency. Whenever any Securities are so surrendered
for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive. All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange. Every Security
presented or surrendered for registration of transfer or for exchange shall (if
so required by the Company or the Trustee) be duly endorsed, or be accompanied
by a written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed, by the Holder thereof or his attorney duly
authorized in writing. No service charge shall be made for any registration of
transfer or exchange of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Sections 304, 305(b), 906, 1108, or 1202 not
involving any transfer. The Company shall not be required (i) to issue, register
the transfer of, or exchange any Security during a period beginning at the
opening of business 15 days before the day of the mailing of a notice of
redemption of Securities selected for redemption under Section 1104 and ending
at the close of business on the day of such mailing, or (ii) to register the
transfer of or exchange any Security so selected for redemption in whole or in
part, except the unredeemed portion of 


   25


any Security being redeemed in part.

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

      Notwithstanding any other provisions in this Indenture, no Global Security
may be transferred to, or registered or exchanged for Securities registered in
the name of, any Person other than the Depositary for such Global Security or
any nominee thereof, and no such transfer may be registered, unless (1) such
Depositary (A) notifies the Company that it is unwilling or unable to continue
as Depositary for such Global Security or (B) ceases to be a clearing agency
registered under the Exchange Act, (2) the Company executes and delivers to the
Trustee a Company Order that such Global Security, shall be so transferable,
registrable and exchangeable, and such transfers shall be registrable, (3) there
shall have occurred and be continuing an Event of Default with respect to the
Securities evidenced by such Global Security or (4) there shall exist such other
circumstances, if any, as have been specified for this purpose as contemplated
by Section 301. Notwithstanding any other provision in this Indenture, a Global
Security to which the restriction set forth in the preceding sentence shall have
ceased to apply may be transferred only to, and may be registered and exchanged
for Securities registered only in the name or names of, such Person or Persons
as the Depositary for such Global Security shall have directed and no transfer
thereof other than such a transfer may be registered.

      Every Security authenticated and delivered upon registration of transfer
of, or in exchange for, or in lieu of, a Global Security to which the
restriction set forth in the first sentence of the preceding paragraph shall
apply, whether pursuant to this Section, Sections 304, 306, 906 or 1007 or
otherwise, shall be authenticated and delivered in the form of, and shall be, a
Global Security.

SECTION 306.   Mutilated, Destroyed, Lost and Stolen Securities.

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

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

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


   26


pay such Security.

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

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

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

SECTION 307.   Payment of Interest; Interest Rights Preserved.

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

      Any interest on any Security which is payable, but is not punctually paid
or duly provided for, within the applicable grace period following any Interest
Payment Date (herein called "Defaulted Interest") shall forthwith cease to be
payable to the Holder on the relevant Regular Record Date notwithstanding the
fact that such Holder was a Holder on such Regular Record Date, and such
Defaulted Interest may be paid by the Company at its election, as provided in
Clause (a) or (b) below:

          (a) The Company may elect to make payment of any Defaulted Interest to
the Persons in whose names the 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 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
shall be not more than 15 days and no less than 10 days prior to the date of the
proposed payment and not less than 10 days after the receipt by the Trustee of
the notice of the proposed payment. The Trustee shall promptly notify the
Company of such Special Record Date and, in the name and at the expense of the
Company, shall cause notice of the proposed payment of such Defaulted Interest
and the Special Record Date therefor to be mailed, first-class postage prepaid,
to each Holder at his address as it appears in the Security Register, not less
than 10 days prior to such Special Record Date. Notice of the 


   27



proposed payment of such Defaulted Interest and the Special Record Date
therefor having been so mailed, such Defaulted Interest shall be paid to the
Persons in whose names the Securities (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 (b).

          (b) The Company may make payment of any Defaulted Interest in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the 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.

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

      In the case of any Security which is converted after any Regular Record
Date and on or prior to the next succeeding Interest Payment Date (other than
any Security whose Maturity is prior to such Interest Payment Date), subject to
the obligation to deliver funds pursuant to Section 1202, interest whose Stated
Maturity is on such Interest Payment Date shall be payable on such Interest
Payment Date notwithstanding such conversion, and such interest (whether or not
punctually paid or duly provided for) shall be paid to the Person in whose name
that Security (or one or more Predecessor Securities) is registered at the close
of business on such Regular Record Date. Except as otherwise expressly provided
in the immediately preceding sentence, in the case of any Security which is
converted, interest whose Stated Maturity is after the date of conversion of
such Security shall not be payable.

SECTION 308.   Persons Deemed Owners.

      Prior to due presentment of a Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name such Security is registered as the owner of such Security
for the purpose of receiving payment of principal of (and premium, if any) and
(subject to Section 307) interest on such Security and for all other purposes
whatsoever, whether or not such Security be overdue, and neither the Company,
the Trustee nor any agent of the Company or the Trustee shall be affected by
notice to the contrary.

SECTION 309.   Cancellation.

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


   28



destruction delivered to the Company.

SECTION 310.   Computation of Interest.

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

                                  ARTICLE FOUR

                           SATISFACTION AND DISCHARGE

SECTION 401.   Satisfaction and Discharge of Indenture.

      This Indenture shall upon Company Request cease to be of further effect
(except as to any surviving rights of conversion, registration of transfer or
exchange of Securities and rights of the Trustee herein expressly provided for),

SECTION 402.   Application of Trust Money.

      Subject to the provisions of the last paragraph of Section 1003, all money
deposited with the Trustee pursuant to Section 401 shall be held in trust and
applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium or
Make-Whole Amount, if any) and interest for whose payment such money has been
deposited with the Trustee. All moneys deposited with the Trustee pursuant to
Section 401 (and held by it or any Paying Agent) for the payment of Securities
subsequently converted shall be returned to the Company upon Company Request.

                                  ARTICLE FIVE

                                    REMEDIES

SECTION 501.   Events of Default.

      "Event of Default," wherever used herein, means any one of the following
events (whatever the reason for such Event of Default and whether it shall be
occasioned by the provisions of Article Thirteen or be voluntary or involuntary
or be effected by operation of law or pursuant to any judgment, decree or order
of any court or any order, rule or regulation of any administrative or
governmental body):

          (1) default for 30 days in the payment of any installment of interest
or Additional Amounts payable upon any Security of such series;

          (2) default in making any sinking fund payment as required for any
Security of such series;

          (3) default in the payment of the Redemption Price in respect of any
Security on the Redemption Date therefor in accordance with the provisions of
Article Eleven;

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

          (5) a default under any bond, debenture, note or other evidence of
indebtedness for money borrowed by the Company (including a default with respect
to Securities of any series other than that series) having an aggregate
principal amount outstanding of at least $10,000,000, or under any mortgage,
indenture or instrument (including this Indenture) under which there may be
issued or by which there may be secured or evidenced any indebtedness for money
borrowed by the Company having an aggregate principal amount outstanding of at
least $10,000,000, whether such 


   30


indebtedness now exists or shall hereafter be created, 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, without
such acceleration having been rescinded or annulled, in each such case within a
period of 10 days after there shall have been given, by registered or certified
mail, to the Company by the Trustee or to the Company and the Trustee by the
Holders of at least 10% in principal amount of the Outstanding Securities of
that series a written notice specifying such default and requiring the Company
to cause such indebtedness to be discharged or cause such acceleration to be
rescinded or annulled, as the case may be, and setting that such notice is a
"Notice of Default" hereunder; provided, however, that, subject to the
provisions of Sections 601 and 602, the Trustee shall not be deemed to have
knowledge of such default unless either (A) a Responsible Officer of the Trustee
shall have actual knowledge of such default or (B) the Trustee shall have
received written notice thereof from the Company, from any Holder, from the
holder of any such indebtedness or from the trustee under such mortgage,
indenture or other instrument;

          (6) certain events of bankruptcy, insolvency or reorganization, or
court appointment of a receiver, liquidator or trustee of the Company or any
Significant Subsidiary or for all or substantially all of either of its
property; and

          (7) any other Event of Default provided with respect to Securities of
that Series.

      The term "Significant Subsidiary" means each significant subsidiary as
defined in Regulation S-X promulgated under the Securities Act of the Company.

SECTION 502.  Acceleration of Maturity, Rescission and Annulment.

      If an Event of Default (other than an Event of Default specified in clause
(6) of Section 501) occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of such series may declare the principal amount (or, if
any of the Securities of that Series are Original Issue Discount Securities or
Indexed Securities, such portion of the principal amount of such Securities as
may be specified in the terms thereof) of, and premium or Make-Whole amount, if
any, on, all the Securities of that series to be due and payable, by a notice in
writing to the Company (and to the Trustee if given by Holders), and such
principal shall become immediately due and payable. If an Event of Default
specified in clause (6) of Section 501 with respect to Securities of any series
at the time Outstanding occurs, the principal amount of all the Securities of
that series (or, if any Securities of that Series are Original Issue Discount
Securities, such portion of the principal amount of such securities as may be
specified in the terms thereof) shall automatically, and without any declaration
or other action on the part of the Trustee or any Holder, shall become
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holder.

      However, at any time after a declaration of acceleration with respect to
Securities of such Series (or of all Securities then Outstanding under the
applicable Indenture, as the case may be) has been made, but before a judgment
or decree for payment of the money due has been obtained by the Trustee, the
Holders of not less than a majority in principal amount of the Outstanding
Securities of 


   31



that series (or of all Securities then Outstanding under the applicable
Indenture, as the case may be), by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if:

          (1) the Company shall have deposited with the Trustee all required
payments of the principal of (and premium or Make-Whole Amount, if any) and
interest, and any Additional Amounts, on the Debt Securities of such series (or
of all Debt Securities then Outstanding under the applicable Indenture, as the
case may be), plus certain fees, expenses, disbursements and advances of the
Trustee; and

          (2) all Events of Default, other than the non-payment of the principal
(or specified portion thereof and the premium or Make-Whole Amount, if any) or
interest, with respect to the Debt Securities of such series (or of all Debt
Securities then Outstanding under the applicable Indenture, as the case may be)
have been cured or waived as provided in the Indenture.

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

SECTION 503.   Collection of Indebtedness and Suits for Enforcement by Trustee.

      The Company covenants that if

          (1) default is made in the payment of any interest on any Security
when such interest becomes due and payable and such default continues for a
period of 30 days, or

          (2) default is made in the payment of the principal of (or premium or
Make-Whole Amount, if any) any Security at the Maturity thereof, including
payment of the Redemption Price on any Redemption Date.

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

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

      If an Event of Default occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem
appropriate to protect and enforce any 


   32



such rights, whether for the specific enforcement of any covenant or agreement
in this Indenture or in aid of the exercise of any power granted herein, or to
enforce any other proper remedy.

SECTION 504.   Trustee May File Proofs of Claim.

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

          (i) to file and prove a claim for the whole amount of principal (and
premium or Make-Whole Amount, if any) and interest and Additional Amounts owing
and unpaid in respect of the Securities and to file such other papers or
documents as may be necessary or advisable and to take any and all actions
authorized under the Trust Indenture Act or any other applicable law as may be
appropriate in order to have the claims of the Trustee (including any claim for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel) and of the Holders allowed in such judicial
proceeding, and

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

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

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

SECTION 505.   Trustee May Enforce Claims Without Possession of Securities.

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


   33



SECTION 506.   Application of Money Collected.

      Subject to Article Thirteen, any money collected by the Trustee pursuant
to this Article shall be applied in the following order, at the date or dates
fixed by the Trustee and, in case of the distribution of such money on account
of principal (or premium or Make-Whole Amount, if any) or interest, upon
presentation of the Securities and the notation thereon of the payment if only
partially paid and upon surrender thereof if fully paid:

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

          SECOND: Subject to Article Thirteen, to the payment of the amounts
then due and unpaid for principal of (and premium or Make-Whole Amount, if any)
and interest on the Securities in respect of which or for the benefit of which
such money has been collected, ratably, without preference or priority of any
kind, according to the amounts due and payable on such Securities for principal
(and premium, if any) and interest, respectively; and

          THIRD: To the payment of the remainder, if any, to whomsoever may be
lawfully entitled thereto, or as a court of competent jurisdiction may direct.

SECTION 507.   Limitation on Suits.

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

          (1) such Holder has previously given written notice to the Trustee of
a continuing Event of Default;

          (2) the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default in its own
name as Trustee hereunder;

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

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

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

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

SECTION 508.   Unconditional Right of Holders to Receive

   34



               Principal, Premium and Interest and to Convert.

      Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of (and premium or Make-Whole Amount, if any) and
(subject to Section 307) interest on such Security on the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on the
Redemption Date) and to convert such Security in accordance with Article Twelve
and to institute suit for the enforcement of any such payment and right to
convert, and such rights shall not be impaired without the consent of such
Holder.

SECTION 509.   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 Trustee and the Holders shall continue as though
no such proceeding had been instituted.

SECTION 510.   Rights and Remedies Cumulative.

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

SECTION 511.   Delay or Omission Not Waiver.

      No delay or omission of the Trustee or of any Holder of any Security to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article or by law to
the Trustee or to the Holders may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee or by the Holders, as the case may
be.

SECTION 512.   Control by Holders.

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

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

          (2) the Trustee may take any other action deemed proper 


   35



by the Trustee which is not inconsistent with such direction.

SECTION 513.   Waiver of Past Defaults.

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

          (1) in the payment of the principal of (or premium, if any) or
interest on any Security,

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

          (3) in respect of the conversion rights under Article Twelve.

      Upon any such waiver, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.

SECTION 514.   Undertaking for Costs.

      In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs against
any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided that neither this Section nor the Trust Indenture Act
shall be deemed to authorize any court to require such an undertaking or to make
such an assessment in any suit instituted by the Company or in any suit for
enforcement of the right to convert any Security in accordance with Article
Twelve.

SECTION 515.   Waiver of Stay or Extension Laws.

      The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                   ARTICLE SIX

                                   THE TRUSTEE

SECTION 601.   Certain Duties and Responsibilities.

      The duties and responsibilities of the Trustee shall be as provided by the
Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee 


   36



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 reasonable assured to it. Whether or not therein expressly so provided,
every provision of this Indenture relating to the conduct or affecting the
liability of or affording protection to the Trustee shall be subject to the
provisions of this Section.

SECTION 602.   Notice of Defaults.

      A Trustee is required to give notice to the Holders of Securities of any
series within 90 days of a default under the applicable Indenture; provided,
however, that a Trustee may withhold notice to the Holders of any series of
Securities of any default with respect to such series (except a default in the
payment of the principal of (or premium or Make-Whole Amount, if any) or
interest or Additional Amounts payable on any Security of such series or in the
payment of any sinking fund installment in respect of any Security of such
series) if the Responsible Officers of such Trustee consider such withholding to
be in the interest of such Holders.

SECTION 603.   Certain Rights of Trustee.

      Subject to the provisions of Section 601:

          (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 Company Order and any resolution
of the Board of Directors may 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 written advice of
such counsel or any Opinion of Counsel shall be full and complete authorization
and protection in respect of any action taken, suffered or omitted by it
hereunder in good faith and in reliance thereon;

          (e) 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 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 


   37



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; and

          (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.

SECTION 604.   Not Responsible for Recitals or Issuance of Securities.

      The recitals contained in the 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 Securities. The Trustee shall not be accountable for the use or
application by the Company of Securities or the proceeds thereof.

SECTION 605.   May Hold Securities.

      The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
608 and 613, may otherwise deal with the Company with the same rights it would
have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

SECTION 606.   Money Held in Trust.

      Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed with the Company.

SECTION 607.   Compensation and Reimbursement.

      The Company agrees:

          (1) to pay to the Trustee from time to time reasonable compensation
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 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 any action or failure to act by 


   38



the Trustee that breaches the applicable standard of care relating thereto; and

          (3) to indemnify the Trustee for, and to hold it harmless against, any
loss, liability or expense incurred unless incurred in connection with any
action or failure to act by the Trustee that breaches the applicable standard of
care relating thereto, arising out of or in connection with the acceptance or
administration of the trust 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.

      When the Trustee incurs expenses or renders services in connection with an
Event of Default specified in clause (6) of Section 501, the expenses (including
the reasonable charges and expenses of its counsel) and the compensation for the
services are intended to constitute expenses of administration under any
applicable federal or state bankruptcy, insolvency or other similar law.

      The provisions of this Section shall survive the termination of this
Indenture.

SECTION 608.   Disqualification; Conflicting Interest.

      The Trustee shall be subject to the provisions of Section 310(b) of the
Trust Indenture Act. Nothing herein shall prevent the Trustee from filing with
the SEC the application referred to in the penultimate paragraph of Section
310(b) of the Trust Indenture Act and this Indenture.

SECTION 609.   Corporate Trustee Required; Eligibility.

      There shall at all times be one or more Trustees hereunder with respect to
the Securities of each series, at least one of which is a Person that is
eligible pursuant to the Trust Indenture Act to act as such and has a combined
capital and surplus of at least $50,000,000 and subject to supervision or
examination by federal or state authority. If such Person publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article.

SECTION 610.   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 in accordance with the
applicable requirements of Section 611.

          (b) The Trustee may resign at any time by giving written notice
thereof to the Company. If the instrument of acceptance by a successor Trustee
required by Section 611 shall not have been delivered to the Trustee within 30
days after the giving of such notice of resignation, the resigning Trustee may
petition any court 


   39



of competent jurisdiction for the appointment of a successor Trustee.

          (c) The Trustee may be removed at any time by Act of the Holders of a
majority in principal amount of the Outstanding Securities, delivered to the
Trustee and to the Company.

          (d)  If at any time:

               (1) the Trustee shall fail to comply with Section 608 after
written request therefor by the Company or by any Holder who has been a bona
fide Holder of a Security for at least six months, or

               (2) the Trustee shall cease to be eligible under Section 609 and
shall fail to resign after written request therefor by the Company or by any

          (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

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee, or (ii) subject to Section 514, any Holder who has been a bona fide
Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee or Trustees.

          (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, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee. If,
within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment, become the
successor Trustee and supersede the successor Trustee appointed by the Company.
If no successor Trustee shall have been so appointed by the Company or the
Holders and accepted appointment in the manner required by Section 611, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the appointment of a successor Trustee.

          (f) The Company shall give notice of each resignation and each removal

Office.

SECTION 611.   Acceptance of Appointment by Successor.

          (a) Every successor Trustee appointed hereunder shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting such appointment, and thereupon the 


   40



resignation or removal of the retiring Trustee shall become effective, the
retiring Trustee shall be released from all obligations for future actions under
this Indenture 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. 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.

          (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (i) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (ii)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(iii) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates.

      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
paragraphs (a) and (b) of this Section, as the case may be.

      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 612.   Merger, Conversion, Consolidation or Succession to Business.

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

SECTION 613.   Preferential Collection of Claims Against Company.

      If and when the Trustee shall be or become a creditor of the Company (or
any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act, regarding the collection of claims
against the Company (or any such other obligor).

SECTION 614.   Appointment of Authenticating Agent.

      The Trustee may appoint an Authenticating Agent or Agents which shall be
authorized to act on behalf of the Trustee to authenticate Securities issued
upon original issue and upon exchange, registration of transfer, partial
conversion or partial redemption thereof or pursuant to Section 306, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business
under the laws of the United States of America, any state thereof or the
District of Columbia, authorized under such laws to act as Authenticating Agent,
having a combined capital and surplus of not less than $50,000,000 and subject
to supervision or examination by federal or state authority. If such
Authenticating Agent publishes reports of condition at least annually pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

      Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any 


   42



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

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

      The Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section, and the Trustee
shall be entitled to be reimbursed for such payments, subject to the provisions
of Section 607.

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

      This is one of the Securities described in the within mentioned Indenture.

                                [insert name of trustee]

Subsidiary at the time of such transaction, no Event of Default, and no event

on overdue amounts at the rate set forth in paragraph 1 of the Securities, and

purchase pursuant to Article Fourteen and where notices and demands to or upon
the Company in respect of the Securities 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

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, and the Company hereby appoints the Trustee as its agent to receive all
such presentations, surrenders, notices and demands.

      The Company may also from time to time designate one or more other offices
or agencies where the Securities of one or more series may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency

notice to the Trustee of any such designation or rescission and of any change in
the location of any such other office or agency.

   49



Amount, if any) or interest on any of the Securities of that series, segregate
and hold in trust for the benefit of the Persons entitled thereto a sum
sufficient to pay the principal (and premium or Make-Whole Amount, 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 so to act.

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

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

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

          (2) give the Trustee notice of any default by the Company (or any
other obligor upon the Securities) in the making of any payment of principal
(and premium or Make-Whole Amount, if any) or interest; 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 or
Make-Whole Amount, if any) or interest on any Security of any series and
remaining unclaimed for two years after such principal (and premium or
Make-Whole Amount, if any) or interest has become due and payable shall be paid
to the Company on Company Request or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Security shall thereafter, as
an unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of 


   50


the Company cause to be published once, in a newspaper published in the English
language, customarily published on each Business Day and of general circulation
in New York, New York, notice that such money remains unclaimed and that, after
a date specified therein, which shall not be less than 30 days from the date of
such publication, any unclaimed balance of such money then remaining, will be
repaid to the Company.

SECTION 1004.   Statements of Officers of Company as to Default.

          (a) The Company will deliver to the Trustee, within 120 days after the
end of each fiscal year of the Company ending after the date hereof (but no
later than the time of filing of the annual report of the Company with the
Trustee pursuant to Section 704), an Officers' Certificate, stating whether or
not to the best knowledge of the signers thereof the Company is in compliance
with all conditions and covenants hereunder, without regard to any period of
grace or requirement of notice provided hereunder. If the Company shall be in
default, specifying all such defaults and the nature and status thereof of which
they may have knowledge. The Officers' Certificate need not comply with Section
102 hereof.

          (b) The Company shall file with the Trustee written notice of the
occurrence of any default or Event of Default within five (5) Business Days of
its becoming aware of any such default or Event of Default.

SECTION 1005.   Existence.

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

SECTION 1006.   Maintenance of Properties.

      The Company will cause all properties material to the conduct of its
business or the business of any Subsidiary to be maintained and kept in good
condition, repair and working order and supplied with all necessary equipment
and will cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in the judgment of the Company, may
be necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times; provided, however, that
nothing in this Section shall prevent the Company from discontinuing the
operation or maintenance of any of such properties if such discontinuance is, in
the judgment of the Company, desirable in the conduct of its business or the
business of any Subsidiary and not disadvantageous in any material respect to
the Holders.

SECTION 1007.   Payment of Taxes and Other Claims.

      The Company shall pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all taxes, assessments and
governmental charges (including withholding taxes and any penalties, interest
and additions to taxes) levied or imposed upon the Company or any Subsidiary or
upon the income, profits or property of the Company or any Subsidiary, and (2)
all 


   51



material lawful claims for labor, materials and supplies which, if unpaid, might
by law become a lien upon the property of the Company or any Subsidiary, in each
case material to the Company and its Subsidiaries taken as a whole; provided,
however, that the Company shall not be required to pay or discharge or cause to
be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings and for which disputed amounts adequate reserves have been made.

SECTION 1008.   Waiver of Certain Covenants.

      The Company may omit in any particular instance to comply with any term,
provision or condition set forth in Article 10, inclusive, with respect to the
Securities of any series, if before the time for such compliance the Holders of
at least a majority (or such greater amount as may be specified in any such
term, provision or condition) in principal amount of the Outstanding Securities
of such series shall, by Act of such Holders, either waive such compliance in
such instance or generally waive compliance with such term, provision or
condition, but no such waiver shall extend to or affect such term, provision or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee
in respect of any such term, provision or condition shall remain in full force
and effect.

SECTION 1009.   Further Instruments and Acts.

      Upon reasonable request of the Trustee, the Company will execute and
deliver such further instruments and perform such further acts as may be
reasonably necessary or proper to carry out more effectively the purposes of
this Indenture, including, but not limited to, any reporting requirements
relating to original issue discount for purposes of federal income taxation.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

SECTION 1101.   Applicability of Article.

      The Securities of any series that are convertible into Shares of Common
Stock will be subject to redemption in whole or from time to time in part, at
any time for certain reasons intended to protect the Company's status as a REIT.

      Securities of any series which are redeemable before their Stated Maturity
shall be redeemable in accordance with their terms and (except as otherwise
specified as contemplated by Section 301 for Securities of any series) in
accordance with this Article.

SECTION 1102.   Election to Redeem; Notice to Trustee.

      The election of the Company to redeem any Securities shall be evidenced by
a Board Resolution. In case of any redemption at the election of the Company,
the Company shall, at least 30 days prior to the Redemption Date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee of such Redemption Date and of the principal amount of Securities to
be redeemed and, if applicable, of the tenor of the Securities to be redeemed.
In the case of any redemption of Securities prior to 


   52


the expiration of any restriction on such redemption provided in the terms of
such Securities or elsewhere in this Indenture, the Company shall furnish the
Trustee with an Officers' Certificate evidencing compliance with such
restriction.

SECTION 1103.  Selection by Trustee of Securities to Be Redeemed.

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

      If less than all of the Securities of such series and of a specified tenor
are to be redeemed, the particular Securities to be redeemed shall be selected
not more than 60 days prior to the Redemption Date by the Trustee, from the
Outstanding Securities of such series and specified tenor not previously called
for redemption in accordance with the preceding sentence.

      If any Security selected for partial redemption is converted in part
before termination of the conversion right with respect to the portion of the
Security so selected, the converted portion of such Security shall be deemed (so
far as may be) to be the portion selected for redemption. Securities which have
been converted during a selection of Securities to be redeemed shall be treated
by the Trustee as Outstanding for the purpose of such selection.

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

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

SECTION 1104.   Notice of Redemption.

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

      All notices of redemption shall state:

          (1)  the Redemption Date,

          (2)  the Redemption Price,

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

   53



Securities to be redeemed,

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

          (5) the conversion price, the date on which the right to convert the
principal of the Securities to be redeemed will terminate and the place or
places where such Securities may be surrendered for conversion, and

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

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

      Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company and shall be irrevocable.

SECTION 1105.   Deposit of Redemption Price.

      Prior to any Redemption Date, the Company shall deposit with the Trustee
or with a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 1003) an amount of money
sufficient to pay the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date) accrued interest on, all the Securities which
are to be redeemed on that date other than any Securities called for redemption
on that date which have been converted prior to the date of such deposit.

      If any Security called for redemption is converted, any money deposited
with the Trustee or with any Paying Agent or so segregated and held in trust for
the redemption of such Security shall (subject to any right of the Holder of
such Security or any Predecessor Security to receive interest as provided in the
last paragraph of Section 307) be paid to the Company upon Company Request or,
if then held by the Company, shall be discharged from such trust.

SECTION 1106.   Securities Payable on Redemption Date.

      Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that unless otherwise specified as
contemplated by Section 301, installments of interest whose Stated Maturity is
on or prior to the Redemption Date shall be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

      If any Security called for redemption shall not be so paid 

   54



upon surrender thereof for redemption the principal (and premium or Make-Whole
Amount, if any) shall, until paid, bear interest from the Redemption Date at the
rate borne by the Security.

SECTION 1107.   Securities Redeemed in Part.

      Any Security which is to be redeemed only in part shall be surrendered at
an office or agency of the Company designated for that purpose pursuant to
Section 1002 (with, if the Company or the Trustee so requires, due endorsement
by, or a written instrument of transfer in form satisfactory to the Company and
the Trustee duly executed by, the Holder thereof or his attorney duly authorized
in writing), and the Company shall execute, and the Trustee shall authenticate
and deliver to the Holder of such Security without service charge, a new
Security or Securities of any authorized denomination as requested by such
Holder, in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered.

SECTION 1108.   Conversion Arrangements on Call for Redemption.

      Notwithstanding anything to the contrary contained in this Indenture, in
connection with any redemption of Securities, the Company, by an agreement with
one or more investment bankers or other purchasers, may arrange for such
purchasers to purchase all Securities called for redemption (the "Called
Securities") which are either (i) surrendered for redemption or (ii) not duly
surrendered for redemption or conversion prior to the close of business on the
Redemption Date, and to convert the same into shares of Common Stock, by the
purchasers' depositing with the Trustee (acting as Paying Agent with respect to
the deposit of such amount and as conversion agent with respect to the
conversion of such Called Securities), in trust for the Holders of the Called
Securities, on or prior to the Redemption Date in the manner agreed to by the
Company and such purchasers, an amount sufficient to pay the Redemption Price,
payable by the Company on redemption of such Called Securities. In connection
with any such arrangement for purchase and conversion, the Trustee as Paying
Agent shall pay on or after the Redemption Date such amounts so deposited by the
purchasers in exchange for Called Securities surrendered for redemption prior to
the close of business on the Redemption Date and for all Called Securities
surrendered after such Redemption Date. Notwithstanding anything to the contrary
contained in this Article Eleven, the obligation of the Company to pay the
Redemption Price of such Called Securities shall be satisfied and discharged to
the extent such amount is so paid by such purchasers, provided, however, that
nothing in this Section 1109 shall in any way relieve the Company of the
obligation to pay such Redemption Price on all Called Securities to the extent
such amount is not so paid by said purchasers. For all purposes of this
Indenture, any Called Securities surrendered by the Holders for redemption, and
any Called Securities not duly surrendered for redemption or conversion prior to
the close of business on the Redemption Date, shall be deemed acquired by such
purchasers from such Holders and surrendered by such purchasers for conversion
and shall in all respects be deemed to have been converted, all as of
immediately prior to the close of business on the Redemption Date, subject to
the deposit by the purchasers of the above amount as aforesaid. Nothing in this
Section 1109 shall in any way limit the right of any Holder of a Security to
convert his Security pursuant to the terms of this Indenture any time prior to
the close of business on the fifth Business Day preceding the Redemption Date.


   55



                                 ARTICLE TWELVE

                            CONVERSION OF SECURITIES

SECTION 1201.   Conversion Privilege and Conversion Price.

      Securities of any series which are convertible into Common Stock of the
Company shall be convertible in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for Securities of any series)
in accordance with this Article.

      Subject to and upon compliance with the provisions of this Article, at the
option of the Holder thereof, any Security or any portion of the principal
amount thereof which is $1,000 or an integral multiple of $1,000 may be
converted at the principal amount thereof, or of such portion thereof, into
fully paid and nonassessable shares (calculated as to each conversion to the
nearest 1/100 of a share) of Common Stock of the Company, at the conversion
price, determined as hereinafter provided, in effect at the time of conversion.
Such conversion right shall expire at the close of business on the date
specified in the description relating to the specific series of the Securities.
In case a Security or portion thereof is called for redemption, such conversion
right in respect of the Security or portion so called shall expire at the close
of business on the fifth Business Day preceding the Redemption Date, unless the
Company defaults in making the payment due upon redemption.

      The price at which shares of Common Stock shall be delivered upon
conversion (herein called the "conversion price") shall be the price specified
in relation to Securities of such series pursuant to Section 301. The conversion
price shall be adjusted in certain instances as provided in this Article.

      In case the Company shall, by dividend or otherwise, declare or make a
distribution on its Common Stock referred to in paragraph (4) or (5) of Section
1204, the Holder of each Security, upon the conversion thereof pursuant to this
Article subsequent to the close of business on the date fixed for the
determination of stockholders entitled to receive such distribution and prior to
the effectiveness of the conversion price adjustment in respect of such
distribution pursuant to paragraph (4) or (5) of Section 1204, shall also be
entitled to receive for each share of Common Stock into which such Security is
converted, the portion of the evidences of indebtedness, shares of capital
stock, cash and assets so distributed applicable to one share of Common Stock,
provided that at the election of the Company (whose election shall be evidenced
by a Board Resolution) with respect to all Holders so converting, the Company
may, in lieu of distributing to such Holder any portion of such distribution not
consisting of cash or securities of the Company, pay such Holder an amount in
cash equal to the fair market value thereof (as determined by the Board of
Directors, whose determination shall be conclusive and described in a Board
Resolution). If any conversion of a Security described in the immediately
preceding sentence occurs prior to the payment date for a distribution to
holders of Common Stock which the Holder of the Security so converted is
entitled to receive in accordance with the immediately preceding sentence, the
Company may elect (such election to be evidenced by a Board Resolution) to
distribute to such Holder a due bill for the evidences of indebtedness, shares
of capital stock, cash or assets to which such Holder is so entitled, provided
that such due bill (i) meets any applicable requirements 


   56



of the principal national securities exchange or other market on which the
Common Stock is then traded and (ii) requires payment or delivery of such
evidences of indebtedness, shares of capital stock, cash or assets no later than
the date of payment or delivery thereof to holders of Common Stock receiving
such distribution.

SECTION 1202.   Exercise of Conversion Privilege.

      In order to exercise the conversion privilege, the Holder of any Security
to be converted shall surrender such Security, duly endorsed or assigned to the
Company or in blank, at any office or agency maintained by the Company pursuant
to Section 1002, accompanied by written notice to the Company (which shall be
substantially in for the form set forth in Section 203) at such office or agency
that the Holder elects to convert such Security or, if less than the entire
principal amount thereof is to be converted, the portion thereof to be
converted. Securities surrendered for conversion during the period from the
close of business on any Regular Record Date next preceding any Interest Payment
Date to the opening of business on such Interest Payment Date shall (except for
Securities whose Maturity is prior to such Interest Payment Date and Securities
called for redemption on a Redemption Date within such period) be accompanied by
payment in New York Clearing House funds or other funds acceptable to the
Company of an amount equal to the interest payable on such Interest Payment Date
on the principal amount of Securities being surrendered for conversion. Subject
to the provisions of Section 307 relating to the payment of Defaulted Interest
by the Company, the interest payment with respect to a Security called for
redemption on a Redemption Date during the period from the close of business on
any Regular Record Date next preceding any Interest Payment Date to the opening
of business on such Interest Payment Date shall be payable on such Interest
Payment Date to the Holder of such Security at the close of business on such
Regular Record Date notwithstanding the conversion of such Security after such
Regular Record Date and prior to such Interest Payment Date, and the Holder
converting such Security need not include a payment of such interest payment
amount upon surrender of such Security for conversion. Except as provided in the
preceding sentence and subject to the last paragraph of Section 307, no payment
or adjustment shall be made upon any conversion on account of any interest
accrued on the Securities surrendered for conversion or on account of any
dividends on the Common Stock issued upon conversion.

      Securities shall be deemed to have been converted immediately prior to the
close of business on the day of surrender of such Securities for conversion in
accordance with the foregoing provisions, and at such time the rights of the
Holders of such Securities as Holders shall cease, and the Person or Persons
entitled to receive the Common Stock issuable upon conversion shall be treated
for all purposes as the record holder or holders of such Common Stock at such
time. As promptly as practicable on or after the conversion date, the Company
shall issue and shall deliver at such office or agency a certificate or
certificates for the number of full shares of Common Stock issuable upon
conversion, together with payment in lieu of any fraction of a share, as
provided in Section 1203.

      In the case of any Security which is converted in part only, upon such
conversion the Company shall execute and the Trustee shall authenticate and
deliver to the Holder thereof, at the expense of the Company, a new Security or
Securities, of authorized 


   57



denominations in aggregate principal amount equal to the unconverted portion of
the principal amount of such Security.

      The Company's delivery to the Holder of the fixed number of shares of the
Common Stock of the Company (and any cash in lieu of any fractional share of
Common Stock) into which the Security is convertible shall be deemed to satisfy
the Company's obligation to pay the principal amount of the Security and all
accrued interest and original issue discount that has not previously been paid.
The Common Stock of the Company so delivered shall be treated as issued first in
payment of accrued interest and original issue discount and then in payment of
principal. Thus, accrued interest and original issue discount shall be treated
as paid rather than canceled, extinguished or forfeited.

      The Holders of Securities of any series may not convert any Security, and
such Security shall not be convertible by any Holder, if as a result of such
conversion any person would then be deemed to beneficially own, directly or
indirectly, 9.8% or more of the then outstanding shares of Common Stock.

SECTION 1203.   Fractions of Shares.

     No fractional shares of Common Stock shall be issued upon conversion of
Securities. If more than one Security shall be surrendered for conversion at one
time by the same Holder, the number of full shares which shall be issuable upon
conversion thereof shall be computed on the basis of the aggregate principal
amount of the Securities (or specified portions thereof) so surrendered. Instead
of any fractional share of Common Stock which would otherwise be issuable upon
conversion of any Security or Securities (or specified portions thereof), the
Company shall pay a cash adjustment (rounded to the nearest cent) in respect of
such fraction in an amount equal to the same fraction of the Closing Price per
share of the Common Stock (consistent with Section 1204(2) below) at the close
of business on the day of conversion (or, if such day is not a Trading Day, on
the Trading Day immediately preceding such day).

SECTION 1204.   Adjustment of Conversion Price.

          (1) In case the Company shall pay or make a dividend or other
distribution on its Common Stock exclusively in Common Stock or shall pay or
make a dividend or other distribution on any other class of capital stock of the
Company which dividend or distribution includes Common Stock, the conversion
price in effect at the opening of business on the day following the date fixed
for the determination of stockholders entitled to receive such dividend or other
distribution shall be reduced by multiplying such conversion price by a fraction
of which the numerator shall be the number of shares of Common Stock outstanding
at the close of business on the date fixed for such determination and the
denominator shall be the sum of such number of shares and the total number of
shares constituting such dividend or other distribution, such reduction to
become effective immediately after the opening of business on the day following
the date fixed for such determination. For the purposes of this paragraph (1),
the number of shares of Common Stock at any time outstanding shall not include
shares held in the treasury of the Company but shall include shares issuable in
respect of scrip certificates issued in lieu of fractions of shares of Common
Stock. The Company shall not pay any dividend or make any distribution on shares
of Common Stock held in the treasury of the Company.


   58



          (2) In case the Company shall pay or make a dividend or other
distribution on its Common Stock consisting exclusively of, or shall otherwise
issue to all holders of its Common Stock, rights or warrants entitling the
holders thereof to subscribe for or purchase shares of Common Stock at a price
per share less than the current market price per share (determined as provided
in paragraph (6) of this Section) of the Common Stock on the date fixed for the
determination of stockholders entitled to receive such rights or warrants, the
conversion price in effect at the opening of business on the day following the
date fixed for such determination shall be reduced by multiplying such
conversion price by a fraction of which the numerator shall be the number of
shares of Common Stock outstanding at the close of business on the date fixed
for such determination plus the number of shares of Common Stock which the
aggregate of the offering price of the total number of shares of Common Stock so
offered for subscription or purchase would purchase at such current market price
and the denominator shall be the number of shares of Common Stock outstanding at
the close of business on the date fixed for such determination plus the number
of shares of Common Stock so offered for subscription or purchase, such
reduction to become effective immediately after the opening of business on the
day following the date fixed for such determination. For the purposes of this
paragraph (2), the number of shares of Common Stock at any time outstanding
shall not include shares held in the treasury of the Company but shall include
shares issuable in respect of scrip certificates issued in lieu of fractions of
shares of Common Stock. The Company shall not issue any rights or warrants in
respect of shares of Common Stock held in the treasury of the Company. If at the
end of the period during which such rights or warrants are convertible into
Common Stock, not all such rights or warrants have been converted into Common
Stock, the adjustment shall be immediately readjusted (on a prospective basis
for any Securities not theretofore converted) to what it would have been based
on the number of additional shares of Common Stock actually issued.

          (3) In case outstanding shares of Common Stock shall be subdivided
into a greater number of shares of Common Stock, the conversion price in effect
at the opening of business on the day following the day upon which such
subdivision becomes effective shall be proportionately reduced, and, conversely,
in case outstanding shares of Common Stock shall each be combined into a smaller
number of shares of Common Stock, the conversion price in effect at the opening
of business on the day following the day upon which such combination becomes
effective shall be proportionately increased, such reduction or increase, as the
case may be, to become effective immediately after the opening of business on
the day following the day upon which such subdivision or combination becomes
effective.

          (4) In case the Company shall, by dividend or otherwise, distribute to
all holders of its Common Stock evidences of its indebtedness, shares of any
class of capital stock, cash or assets (including securities, but excluding (x)
any rights or warrants referred to in paragraph (2) of this Section, (y) any
dividend or distribution paid exclusively in cash out of the retained earnings
of the Company and (z) any dividend or distribution referred to in paragraph (1)
of this Section), the conversion price shall be adjusted so that the same shall
equal the price determined by multiplying the conversion price in effect
immediately prior to the close of business on the date fixed for the
determination of stockholders entitled to receive such distribution by a
fraction of which the numerator shall be the current market price per share

   59



(determined as provided in paragraph (6) of this Section) of the Common Stock on
the date fixed for such determination less the then fair market value (as
determined by the Board of Directors, whose determination shall be conclusive
and described in a Board Resolution filed with the Trustee) of the portion of
the assets or evidences of indebtedness so distributed applicable to one share
of Common Stock and the denominator shall all be such current market price per
share of the Common Stock, such adjustment to become effective immediately prior
to the opening of business on the day following the date fixed for the
determination of stockholders entitled to receive such distribution.

          (5) The reclassification of Common Stock into securities other than
Common Stock (other than any reclassification upon a consolidation or merger to
which Section 1211 applies) shall be deemed to involve (a) a distribution of
such securities other than Common Stock to all holders of Common Stock (and the
effective date of such reclassification shall be deemed to be "the date fixed
for the determination of stockholders entitled to receive such distribution" and
the "date fixed for such determination" within the meaning of paragraph (4) of
this Section), and (b) a subdivision or combination, as the case may be, of the
number of shares of Common Stock outstanding immediately prior to such
reclassification into the number of shares of Common Stock outstanding
immediately thereafter (and the effective date of such reclassification shall be
deemed to be "the day upon which such subdivision becomes effective" or "the day
upon which such combination becomes effective," as the case may be, such "the
day upon which such subdivision or combination becomes effective" within the
meaning of paragraph (3) of this Section).

          (6) For the purpose of any computation under paragraphs (2) and (4) of
this Section, the current market price per share of Common Stock on any day
shall be deemed to be the average of the daily closing prices for the five
consecutive trading days (i.e., Business Days on which the Common Stock is
traded) selected by the Board of Directors commencing not more than 20 trading
days before, and ending not later than, the earlier of the day in question and
the day before the "ex" date with respect to the issuance or distribution
requiring such computation. For this purpose, the term "'ex' date," when used
with respect to any issuance or distribution, shall mean the first date on which
the Common Stock trades regular way on the applicable exchange or in the
applicable market without the right to receive such issuance or distribution.
The closing price for each day shall be the reported last sale price regular way
or, in case no such reported sale takes place on such day, the average of the
reported closing bid and asked prices regular way, in either case on the New
York Stock Exchange or, if the Common Stock is not listed or admitted to trading
on such Exchange, on the principal national securities exchange on which the
Common Stock is listed or admitted to trading or, if not listed or admitted to
trading on any national securities exchange, on the National Association of
Securities Dealers Automated Quotations National market or, if the Common Stock
is not listed or admitted to trading on any national securities exchange or
quoted on such National Market, the average of the closing bid and asked prices
in the over-the-counter market as furnished by any New York Stock Exchange
member firm selected from time to time by the Board of Directors for that
purpose.

          (7) The Company may make such reductions in the conversion price, in
addition to those required by paragraphs (1), (2), (3) and (4) of this Section,
as it considers to be advisable 


   60



in order to avoid or diminish any income tax to any holders of shares of Common
Stock resulting from any dividend or distribution of stock or issuance of rights
or warrants to purchase or subscribe for stock or from any event treated as such
for income tax purposes or for any other reasons. The Company shall have the
power to resolve any ambiguity or correct any error in this paragraph (7) and
its actions in so doing shall be final and conclusive.

          (8) No adjustment in the conversion price shall be required unless
such adjustment would require an increase or decrease of at least 1% in the
conversion price; provided, however, that any adjustments which by reason of
this paragraph (11) are not required to be made shall be carried forward and
taken into account in any subsequent adjustment. All calculations under this
Article shall be made to the nearest cent or to the nearest 1/100 of a share, as
the case may be.

SECTION 1205.   Notice of Adjustments of Conversion Price.

      Whenever the conversion price is adjusted as herein provided:

          (a) the Company shall compute the adjusted conversion price in
accordance with Section 1204 and shall prepare a certificate signed by the
Treasurer of the Company setting forth the adjusted conversion price and showing
in reasonable detail the facts upon which such adjustment is based, and such
certificate shall forthwith be filed (with a copy to the Trustee) at each office
or agency maintained for the purpose of conversion of Securities pursuant to
Section 1002; and

          (b) a notice stating that the conversion price has been adjusted and
setting forth the adjusted conversion price shall forthwith be required, and as
soon as practicable after it is required, such notice shall be mailed by the
Company to all Holders at their last addresses as they shall appear in the
Security Register.

SECTION 1206.   Notice of Certain Corporate Activities.

      In case:

          (a) the Company shall declare a dividend (or any other distribution)
on its Common Stock payable otherwise than in cash out of its earned surplus; or

          (b) the Company shall authorize the granting to the holders of its
Common Stock of rights or warrants to subscribe for or purchase any shares of
capital stock of any class or of any other rights; or

          (c) of any reclassification of the Common Stock of the Company (other
than a subdivision or combination of its outstanding shares of Common Stock), or
of any consolidation, merger or share exchange to which the Company is a party
and for which approval of any stockholders of the Company is required, or of the
sale or transfer of all or substantially all of the assets of the Company; or

          (d)  of the voluntary or involuntary dissolution,
liquidation or winding up of the Company;

then the Company shall cause to be filed at each office or agency maintained for
the purpose of conversion of Securities pursuant to 

   61



Section 1002, and shall cause to be mailed to all Holders at their last
addresses as they shall appear in the Security Register, at least 20 days (or 10
days in any case specified in clause (a) and (b) above) prior to the applicable
record, effective or expiration date hereinafter specified, a notice stating (x)
the date on which a record is to be taken for the purpose of such dividend,
distribution or granting of rights, warrants or options, or, if a record is not
to be taken, the date as of which the holders of Common Stock of record to be
entitled to such dividend, distribution, rights, warrants or options are to be
determined, or (y) the date on which such reclassification, consolidation,
merger, sale, transfer, dissolution, liquidation or winding up is expected to
become effective, and the date as of which it is expected that holders of Common
Stock of record shall be entitled to exchange their shares of Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding up.
Neither the failure to give such notice nor any defect therein shall affect the
legality or validity of the proceedings described in clauses (a) through (d) of
this Section 1406. If at the time the Trustee shall not be the conversion agent,
a copy of such notice shall also forthwith be filed by the Company with the
Trustee.

SECTION 1207.   Company to Reserve Common Stock.

      The Company shall at all times reserve and keep available, free from
preemptive rights, out of its authorized but unissued Common Stock, for the
purpose of effecting the conversion of Securities, the full number of shares of
Common Stock then issuable upon the conversion of all outstanding Securities.

SECTION 1208.   Taxes on Conversions.

      The Company will pay any and all taxes that may be payable in respect of
the issue or delivery of shares of Common Stock on conversion of Securities
pursuant hereto. The Company shall not, however, be required to pay any tax
which may be payable in respect of any transfer involved in the issue and
delivery of shares of Common Stock in a name other than that of the Holder of
the Security or Securities to be converted, and no such issue or delivery shall
be made unless and until the Person requesting such issue has paid to the
Company or Securities Registrar the amount of any such tax, or has established
to the satisfaction of the Company or Securities Registrar that such tax has
been paid.

SECTION 1209.   Covenant as to Common Stock.

      The Company covenants that all shares of Common Stock which may be issued
upon conversion of Securities will upon issue be fully paid and nonassessable
and, except as provided in Section 1208, the Company will pay all taxes, liens
and charges with respect to the issue thereof.

      The Company will endeavor promptly to comply with all federal and state
securities laws regulating the offer and delivery of shares of Common Stock upon
conversion of Securities, if any, and will list or cause to have quoted such
shares of Common Stock on each national securities exchange or in the
over-the-counter market or such other market on which the Common Stock is then
listed or quoted.

SECTION 1210.   Cancellation of Converted Securities.

      All Securities delivered for conversion shall be delivered to 

   62



the Trustee to be canceled by or at the direction of the Trustee, which shall
dispose of the same as provided in Section 309.

SECTION 1211.   Provisions in Case of Consolidation, Merger or Sale of Assets.

      In case of any consolidation of the Company with, or merger of the Company
into, any other Person, any merger of another Person into the Company (other
than a merger which does not result in any reclassification, conversion,
exchange or cancellation of outstanding shares of Common Stock of the Company)
or any sale, transfer or lease of the Company's properties or assets
substantially as an entirety, the Person formed by such consolidation or
resulting from such merger or which acquires such assets, as the case may be,
shall execute and deliver to the Trustee a supplemental indenture providing that
the Holder of each Security then outstanding and such Person shall have the
right thereafter, during the period such Security shall be convertible as
specified in Section 1201, to convert such Security only into the kind and
amount of securities, cash and other property receivable, if any, upon such
consolidation, merger, sale, transfer or lease by a holder of the number of
shares of Common Stock of the Company into which such Security might have been
converted immediately prior to such consolidation, merger, sale, transfer or
lease, assuming such holder of Common Stock of the Company (i) is not a Person
with which the Company consolidated or into which the Company merged or which
merged into the Company or to which such sale, transfer or lease was made, as
the case may be ("Constituent Person"), or an Affiliate of a Constituent Person
and (ii) failed to exercise his rights of election, if any, as to the kind or
amount of securities, cash and other property receivable upon such
consolidation, merger, sale, transfer or lease (provided that if the kind or
amount of securities, cash and other property receivable upon such
consolidation, merger, sale, transfer or lease is not the same for each share of
Common Stock of the Company held immediately prior to such consolidation,
merger, sale, transfer or lease by other than a Constituent Person or an
Affiliate thereof and in respect of which such rights of election shall not have
been exercised ("non-electing share"), then for the purpose of this Section the
kind and amount of securities, cash and other property receivable upon such
consolidation, merger, sale, transfer or lease by each non-electing share shall
be deemed to be the kind and amount so receivable per share by a plurality of
the non-electing shares). Such supplemental indenture shall provide for
adjustments which, for events subsequent to the effective date of such
supplemental indenture, shall be as nearly equivalent as may be practicable to
the adjustments provided for in this Article. The above provisions of this
Section shall similarly apply to successive consolidations, mergers, sales,
transfers and leases.

SECTION 1212.   Trustee Adjustment Disclaimer.

      Neither the Trustee nor any conversion agent shall at any time be under
any duty or responsibility to any Holder of Securities to determine whether any
fact exists which may require any adjustment of the conversion price, 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
provided to be employed, in making the same. Neither the Trustee nor any
conversion agent shall be accountable with respect to the registration, validity
or value (or the kind or amount) of any shares of Common Stock, or of any
securities or property, which may at any time be issued or delivered upon the
conversion of any 


   63



Security; and neither the Trustee nor any conversion agent makes any
representation with respect thereto. Neither the Trustee nor any conversion
agent shall be responsible for any failure of the Company to issue or transfer
or deliver any Common Stock or stock certificates or other securities or
property or to make any cash payment upon the surrender of any Security for the
purpose of conversion or to comply with any of the covenants of the Company
contained in this Article Twelve.

                                ARTICLE THIRTEEN

                           SUBORDINATION OF SECURITIES

SECTION 1301.   Agreement to Subordinate by Company.

      Notwithstanding anything in this Indenture to the contrary (other than the
last paragraph of Section 1405), the Company, for itself, its successors and
assigns, covenants and agrees, and each Holder of Securities, by his acceptance
thereof, likewise covenants and agrees, that payment by the Company of the
principal of (and premium or Make-Whole Amount, if any) and interest on each and
all of the Securities is hereby expressly subordinated, to the extent and in the
manner hereinafter set forth, in right of payment to the prior payment in full
of all Senior Indebtedness.

SECTION 1302.   Distribution on Dissolution, Liquidation and Reorganization.

      Upon any distribution of assets of the Company upon any dissolution,
winding up, liquidation or reorganization of the Company, whether in bankruptcy,
insolvency, reorganization or receivership proceedings or upon an assignment for
the benefit of creditors or any other marshalling of the assets and liabilities
of the Company or otherwise (subject to the power of a court of competent
jurisdiction to make other equitable provision reflecting the rights conferred
in this Indenture upon the Senior Indebtedness and the holders thereof, with
respect to the Securities and the holders thereof, by a lawful plan of
reorganization under applicable bankruptcy law),

          (a) the holders of all Senior Indebtedness shall be entitled to
receive payment in full of the principal thereof, premium, if any, and the
interest due thereon before the Holders of the Securities are entitled to
receive any payment upon the principal of or premium, if any, or interest on
indebtedness evidenced by the Securities; and

          (b) any payment or distribution of assets of the Company of any kind
or character, whether in cash, property or securities, to which the Holders of
the Securities or the Trustee would be entitled except for the provisions of
this Article Thirteen shall be paid by the liquidating trustee or agent or other
person making such payment or distribution, whether a trustee in bankruptcy, a
receiver or liquidating trustee or otherwise, directly to the holders of Senior
Indebtedness or their representative or representatives or to the trustee or
trustees under any indenture under which any instruments evidencing any of such
Senior Indebtedness may have been issued, ratably according to the aggregate
amounts remaining unpaid on account of the principal of, premium, if any, and
interest on the Senior Indebtedness held or represented by each, to the extent
necessary to make payment in full of all Senior Indebtedness remaining unpaid,
after giving 

   64



effect to any concurrent payment or distribution to the holders of such Senior
Indebtedness; and

          (c) in the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, shall be received by the Holders of the Securities or by
the Trustee before all Senior Indebtedness is paid in full, such payment or
distribution shall be paid over to the holders of such Senior Indebtedness, or
their representative or representatives or to the trustee or trustees under any
indenture under which any instruments evidencing any of such Senior Indebtedness
may have been issued, ratably as aforesaid, for application to the payment of
all Senior Indebtedness remaining unpaid until all such Senior Indebtedness
shall have been paid in full, after giving effect to any concurrent payment or
distribution to the holders of such Senior Indebtedness.

      For purposes of this Article only, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment which are subordinated
in right of payment to all Senior Indebtedness which may at the time be
outstanding to substantially the same extent as, or to a greater extent then,
the Securities are so subordinated as provided in this Article. The
consolidation of the Company with, or the merger of the Company into, another
Person or the liquidation or dissolution of the Company following the conveyance
or transfer of its properties and assets substantially as an entirety to another
Person upon the terms and conditions set forth in Article Eight shall not be
deemed a dissolution, winding up, liquidation, reorganization, assignment for
the benefit of creditors or marshalling of assets and liabilities of the Company
for the purposes of this Section if the Person formed by such consolidation or
into which the Company is merged or which acquires by conveyance or transfer
such properties and assets substantially as an entirety, as the case may be,
shall, as a part of such consolidation, merger, conveyance or transfer, comply
with the conditions set forth in Article Eight.

SECTION 1303.   Subrogation to Rights of Holders of Senior Indebtedness.

      Subject to the payment in full of all Senior Indebtedness, the Holders of
the Securities shall be subrogated to the rights of the holders of Senior
Indebtedness to receive payments or distributions of cash, property or
securities of the Company, applicable to Senior Indebtedness until the principal
of, premium, if any, and interest on the Securities shall be paid in full and no
such payments or distributions to the Holders of the Securities of cash,
property or securities otherwise distributable to the holders of Senior
Indebtedness shall, as between the Company, its creditors other than the holders
of Senior Indebtedness and the Holders of the Securities be deemed to be a
payment by the Company to or on account of the Securities. It is understood that
the provisions of this Article Thirteen are and are intended solely for the
purpose of defining the relative rights of the Holders of the Securities on the
one hand, and the holders of Senior Indebtedness on the other hand. Nothing
contained in this Article Thirteen or elsewhere in this Indenture or in the
Securities is intended to or shall impair, as between the Company, its creditors
other than the holders of Senior Indebtedness and the Holders of the Securities,
as the case may be, the obligations of the Company, which are unconditional and


   65



absolute, to pay to the Holders of the Securities the principal of, premium, if
any, and interest on the Securities as and when the same shall become due and
payable in accordance with their terms, or to affect the relative rights of the
Holders of the Securities and creditors of the Company other than the holders of
Senior Indebtedness, nor shall anything herein or in the Securities prevent the
Trustee or the Holder of any Security from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture, subject to the
rights, if any, under this Article Thirteen of the holders of Senior
Indebtedness in respect of cash, property or securities of the Company received
upon the exercise of any such remedy. Upon any payment or distribution of assets
of the Company referred to in this Article Thirteen, the Trustee, subject to the
provisions of Section 601, shall be entitled to rely upon a certificate of the
liquidating trustee or agent or other person making any distribution to the
Trustee for the purpose of ascertaining the persons entitled to participate in
such distribution, the holders of Senior Indebtedness and other indebtedness of
the Company, the amount thereof or payable thereon, the amount or amounts paid
or distributed thereon and all other facts pertinent thereto or to this Article
Thirteen.

SECTION 1304.   Trustee Not Fiduciary for Holders of Senior Indebtedness.

      The Trustee, however, shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness. The Trustee shall not be liable to any such
holder if it shall pay over or distribute to or on behalf of Holders of
Securities or the Company moneys or assets to which any holder of Senior
Indebtedness shall be entitled by virtue of this Article Thirteen.

      If the Trustee or any Holder of Securities does not file a proper claim or
proof of debt in the form required in any proceeding referred to above prior to
30 days before the expiration of the time to file such claim in such proceeding,
then the holder of any Senior Indebtedness is hereby authorized, and has the
right, to file an appropriate claim or claims for or on behalf of such Holder of
Securities.

SECTION 1305.   Prior Payment to Senior Indebtedness Upon Acceleration of 
                Securities.

      In the event that any Securities are declared due and payable before their
Stated Maturity, then and in such event the holders of Senior Indebtedness
outstanding at the time such Securities so become due and payable shall be
entitled to receive payment in full of all amounts due or to become due on or in
respect of such Senior Indebtedness, or provision shall be made for such payment
in money or money's worth, before the Holders of the Securities are entitled to
receive any payment by the Company on account of the principal of (or premium or
Make-Whole Amount, if any) or interest on the Securities or on account of the
purchase or other acquisition of Securities; provided, however, that nothing in
this Section shall prevent the satisfaction of any sinking fund payment in
accordance with Article Fifteen by delivering and crediting pursuant to Section
1502 Securities which have been acquired (upon redemption or otherwise) prior to
such default or which have been converted pursuant to Article Twelve.

      In the event that, notwithstanding the foregoing, the Company shall make
any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, and if such 


   66


fact shall, at or prior to the time of such payment, have been made known to the
Trustee or, as the case may be, such Holder, then and in such event such payment
shall be paid over and delivered forthwith to the Company.

      The provisions of this Section shall not apply to any payment with respect
to which Section 1302 would be applicable.

SECTION 1306.   No Payment in Event of Default on Senior Indebtedness.

          (a) In the event and during the continuation of any default in the
payment of principal of (or premium or Make-Whole Amount, if any) or interest on
any Senior Indebtedness beyond any applicable grace period with respect thereto,
or in the event that any event of default with respect to any Senior
Indebtedness shall have occurred and be continuing and shall have resulted in
such Senior Indebtedness becoming or being declared due and payable prior to the
date on which it would otherwise have become due and payable, unless and until
such event of default shall have been cured or waived or shall have ceased to
exist and such acceleration shall have been rescinded or annulled, or (b) in the
event any judicial proceeding shall be pending with respect to any such default
in payment or event of default, then no payment shall be made by the Company on
account of principal of (or premium or Make-Whole Amount, if any) or interest
on the Securities or on account of the purchase or other acquisition of
Securities; provided, however, that nothing in this Section shall prevent the
satisfaction of any sinking fund payment in accordance with Article Fifteen by
delivering and crediting pursuant to Section 1502 Securities which have been
acquired (upon redemption or otherwise) prior to such default or which have been
converted pursuant to Article Twelve.

      In the event that, notwithstanding the foregoing, the Company shall make
any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, and if such fact shall, at or prior to the
time of such payment, have been made known to the Trustee or, as the case may
be, such Holder, then and in such event such payment shall be paid over and
delivered forthwith to the Company.

      The provisions of this Section shall not apply to any payment with respect
to which Section 1302 would be applied.

SECTION 1307.   Payments Permitted If No Default.

      Nothing contained in this Article or elsewhere in this Indenture or in any
of the Securities shall prevent the Company, at any time except during the
pendency of any case, proceeding, dissolution, liquidation or other winding up,
assignment for the benefit of creditors or other marshalling of assets and
liabilities of the Company referred to in Section 1302 or under the conditions
described in Section 1305 or 1306, from making payments at any time of principal
of (and premium, or Make-Whole Amount, if any) or interest on securities.

SECTION 1308.   Provisions Solely to Define Relative Rights.

      The provisions of this Article are and are intended solely for the purpose
of defining the relative rights of the Holders of the Securities on the one hand
and the holders of Senior Indebtedness on the other hand. Nothing contained in
this Article or elsewhere in this Indenture or in the Securities is intended to


   67



or shall (a) impair, as among the Company, its creditors other than holders of
Senior Indebtedness and the Holders of the Securities, the obligation of the
Company, which is absolute and unconditional (and which, subject to the rights
under this Article of the holders of Senior Indebtedness, is intended to rank
equally with all other general obligations of the Company), to pay to the
Holders of the Securities the principal of (and premium or Make-Whole Amount, if
any) and interest on the Securities as and when the same shall become due and
payable in accordance with their terms; or (b) affect the relative rights
against the Company of the Holders of the Securities and creditors of the
Company other than the holders of Senior Indebtedness; or (c) prevent the
Trustee or the Holder of any Security from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture, subject to the
rights, if any, under this Article of the holders of Senior Indebtedness to
receive cash, property and securities otherwise payable or deliverable to the
Trustee or such Holder.

SECTION 1309.   Authorization to Trustee to Effect Subordination.

      Each Holder of Securities by his acceptance thereof authorizes and directs
the Trustee in his behalf to take such action as may be necessary or appropriate
to effectuate the subordination as provided in this Article Thirteen and
appoints the Trustee his attorney-in-fact for any and all such purposes.

SECTION 1310.   No Waiver of Subordination Provisions.

      No right of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided such at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith, by any such holder, or by any
non-compliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof any such holder may have or be
otherwise charged with.

      Without in any way limiting the generality of the foregoing paragraph, the
holders of Senior Indebtedness may, at any time and from time to time, without
the consent of or notice to the Trustee or the Holders of the Securities,
without incurring responsibility to the Holders of the Securities and without
impairing or releasing the subordination provided in this Article of the
obligations hereunder of the Holders of the Securities to the holders of Senior
Indebtedness, do any one or more of the following: (i) change the manner, place
or terms of payment or extend the time of payment of, or renew or alter, Senior
Indebtedness, or otherwise amend or supplement in any manner Senior Indebtedness
or any instrument evidencing the same or any agreement under which Senior
Indebtedness is outstanding; (ii) sell, exchange, release or otherwise deal with
any property pledged, mortgaged or otherwise securing Senior Indebtedness; (iii)
release any Person liable in any manner for the collection of Senior
Indebtedness, and (iv) exercise or refrain from exercising any rights against
the Company and any other Person.

SECTION 1311.   Notices to Trustee.

      Notwithstanding the provisions of this Article or any other provisions of
this Indenture, neither the Trustee nor any Paying Agent (other than the
Company) shall be charged with knowledge of the existence of any Senior
Indebtedness or of any event which would prohibit the making of any payment of
moneys to or by the 


   68



Trustee or such Paying Agent, unless and until the Trustee or such Paying Agent
shall have received (in the case of the Trustee, at its Corporate Trust Office)
written notice thereof from the Company or from the holder of any Senior
Indebtedness or from the trustee for any such holder, together with proof
satisfactory to the Trustee of such holding of Senior Indebtedness or of the
authority of such trustee; provided, however, that if at least two Business Days
prior to the date upon which by the terms hereof any such moneys may become
payable for any purpose (including, without limitation, the payment of either
the principal of, premium or Make-Whole Amount, if any, or interest on any
Security) the Trustee shall not have received with respect to any such moneys
the notice provided for in this Section 1311, then, anything herein contained to
the contrary notwithstanding, the Trustee, subject to the provisions of 601,
shall have the full power and authority to receive such moneys and to apply the
same to the purpose for which they were received, and shall not be affected by
any notice to the contrary, which may be received by it on or after such two
Business Days prior to such date. Subject to the provisions of Section 601, the
Trustee shall be entitled to rely on the delivery to it of a written notice by a
person representing himself to be a holder of Senior Indebtedness (or a trustee
on behalf of such holder) to establish that such a notice has been given by a
holder of Senior Indebtedness or a trustee on behalf of any such holder. In the
event that the Trustee determines in good faith that further evidence is
required with respect to the right of any person as a holder of Senior
Indebtedness to participate in any payment or distribution pursuant to this
Article Thirteen, the Trustee may request such person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such person, the extent to which such person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
such person under this Article Thirteen and, if such evidence is not furnished,
the Trustee may defer any payment to such person pending judicial determination
as to the right of such person to receive such payment.

SECTION 1312.   Trustee as Holder of Senior Indebtedness.

     The Trustee shall be entitled to all the rights set forth in this Article
Thirteen in respect of any Senior Indebtedness at any time held by it to the
same extent as any other holder of Senior Indebtedness and nothing in Section
613 or elsewhere in this Indenture shall be construed to deprive the Trustee of
any of its rights as such holder.

SECTION 1313.   Reliance on Judicial Order or Certificate of Liquidating Agent.

      Upon any payment or distribution of assets of the Company referred to in
this Article, the Trustee, subject to the provisions of Section 601, and the
Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit
of creditors, agent or other Person making such payment or distribution,
delivered to the Trustee or to the Holders of Securities, for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, the holders of the Senior Indebtedness and other indebtedness of
the Company, the amount thereof or payable thereon, the amount or amounts paid
or 


   69



distributed thereon and all other facts pertinent thereto or to this Article.

SECTION 1314.   Rights of Trustee as Holder of Senior Indebtedness; Preservation
                of Trustee's Rights.

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

      Nothing in this Article shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 607.

SECTION 1315.   Article Applicable to Paying Agents.

      In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article shall in such case (unless the context otherwise
requires) be construed as extending to and including such Paying Agent within
its meaning as fully for all intents and purposes as if such Paying Agent were
named in this Article in addition to or in place of the Trustee; provided,
however, that Section 1315 shall not apply to the Company or any Affiliate of
the Company if it or such Affiliate acts as Paying Agent.

SECTION 1316.   Certain Conversions Deemed Payment.

      For the purposes of this Article only, (1) the issuance and delivery of
junior securities upon conversion of Securities in accordance with Article
Twelve shall not be deemed to constitute a payment or distribution on account of
the principal of or premium or interest on Securities or on account of the
purchase or other acquisition of Securities, and (2) the payment, issuance or
delivery of cash, property or securities (other than junior securities) upon
conversion of a Security shall be deemed to constitute payment on account of the
principal of such Security. For the purposes of this Section, the term "junior
securities" means (a) shares of any stock of any class of the Company and (b)
securities of the Company which are subordinated in right of payment to all
Senior Indebtedness which may be outstanding at the time of issuance or delivery
of such securities to substantially the same extent as, or to a greater extent
than, the Securities are so subordinated as provided in this Article. Nothing
contained in this Article or elsewhere in this Indenture or in the Securities is
intended to or shall impair, as among the Company, its creditors other than
holders of Senior Indebtedness and the Holders of the Securities, the right,
which is absolute and unconditional, of the Holder of any Security to convert
such Security in accordance with Article Fourteen.

SECTION 1317.   Trust Moneys Not Subordinated.

      Notwithstanding anything contained herein to the contrary, payments from
moneys or the proceeds of U.S. Government Obligations held in trust under
Article Thirteen by the Trustee for the payment of principal of, premium, if
any, and interest on the Securities from the date of deposit (if made in
compliance with this Indenture) shall not be subordinated to the prior payment
of any Senior Indebtedness or subject to the restraints set forth in this



   70


Article, and none of the Security holders shall be obligated to pay over any
such amount to the Company or any holder of Senior Indebtedness of the Company
or any other creditor of the Company.

SECTION 1318.   Modification of Terms of Senior Indebtedness.

      Any renewal or extension of the time of payment of any Senior Indebtedness
or the exercise by the holders of Senior Indebtedness of any of their rights
under any instrument creating or evidencing Senior Indebtedness, including
without limitation the waiver of defaults thereunder, may be made or done all
without notice to or assent from the Holders of the Securities or the Trustee.

      No compromise, alteration, amendment, modification, extension, renewal or
other change of, or waiver, consent or other action in respect of, any liability
or obligation under or in respect of, or of any of the terms, covenants or
conditions of any indenture or other instrument under which any Senior
Indebtedness or of such Senior Indebtedness, whether or not such release is in
accordance with the provisions of any applicable document, shall in any way
alter or affect any of the provisions of this Article Thirteen or of the
Securities relating to the subordination thereof.

                                ARTICLE FOURTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

SECTION 1401.   Company's Option to Effect Defeasance or Covenant Defeasance.

      The Company may at its option by Board Resolution, at any time, elect to
have either Section 1402 or Section 1403 applied to the Outstanding Securities
of any series designated pursuant to Section 301 as being defeasible pursuant to
this Article Fourteen (hereinafter called a "Defeasible Series"), upon
compliance with the conditions set forth below in this Article Fourteen;
provided that Section 1502 shall not apply to any series of Securities that is
convertible into Common Stock as provided in Article Twelve or convertible into
or exchangeable for any other securities pursuant to Section 301(18).

SECTION 1402.   Defeasance and Discharge.

      Upon the Company's exercise of the option provided in Section 1401 to have
this Section 1402 applied to the Outstanding Securities of any Defeasible Series
and subject to the proviso of Section 1401, the Company shall be deemed to have
been discharged from its obligations with respect to the Outstanding Securities
of such series (including the provisions of Article Fourteen hereof) on the date
the conditions set forth in Section 1404 are satisfied (hereinafter,
"Defeasance"). For this purpose, such Defeasance means that the Company shall be
deemed to have paid and discharged the entire indebtedness represented by the
Outstanding Securities of such series and to have satisfied all its other
obligations under such Securities of such series and this Indenture insofar as
such Securities are concerned (and the Trustee, at the expense of the Company,
shall execute proper instruments acknowledging the same), except for the
following which shall survive until otherwise terminated or discharged
hereunder: (A) the rights of Holders of Outstanding Securities of such series to
receive, solely from the trust fund described in Section 1404 and as more fully
set forth in 


   71



such Section, payments in respect of the principal of and premium or Make-Whole
Amount, if any) and interest on such Securities when such payments are due, (B)
the Company's obligations with respect to such Securities under Sections 304,
305, 306, 1002 and 1003, (C) the rights, powers, trusts, duties and immunities
of the Trustee hereunder, (D) the Company's obligations under Article Twelve and
(E) this Article Fourteen.

      Subject to compliance with this Article Fourteen, the Company may exercise
its option under this Section 1402 applied to the Outstanding Securities of any
Defeasible Series notwithstanding the prior exercise of the option provided in
Section 1401 to have Section 1403 applied to the outstanding Securities of such
series.

SECTION 1403.   Covenant Defeasance.

       Upon the Company's exercise of the option provided in Section 1403 to
have this Section 1303 applied to the Outstanding Securities of any Defeasible
Series, (1) the Company shall be released from its obligations under Sections
1006 through 1009, inclusive, and Section 801(3), and any covenants provided
pursuant to Section 301(20), 901(2) or 901(7) for the benefit of the Holders of
such Securities and (2) the occurrence of any event specified in Sections
501(3), 501(4) (with respect to any of Sections 1006 through 1009, inclusive,
and any such covenant provided pursuant to Section 301(20), 901(2) or 901(7) and
Section 801(3), 501(5) and 501(8) shall be deemed not to be or result in an
Event of Default and (3) the provisions of Article Fifteen shall cause to be
effective, in each case with respect to the Outstanding Securities of such
series as provided in this Section on and after the date the conditions set
forth in Section 1404 are satisfied (hereinafter called "Covenant Defeasance").
For this purpose, such Covenant Defeasance means that the Company may omit to
comply with and shall have no liability in respect of any term, condition or
limitation set forth in any such Sections or Article whether directly or
indirectly by reason of any reference elsewhere herein to any such Sections or
Article or by reason of any reference in any such Sections or Article to any
other provision herein or in any other document, but the remainder of this
Indenture and such Securities shall be unaffected thereby.

SECTION 1404.   Conditions to Defeasance or Covenant Defeasance.

      The following shall be the conditions to application of either Section
1402 or Section 1403 to the Outstanding Securities:

          (1) The Company shall irrevocably have deposited or caused to be
deposited with the Trustee (or another trustee satisfying the requirements of
Section 609 who shall agree to comply with the provisions of this Article
Fifteen applicable to it) as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to, the benefit of the Holders of outstanding Securities of such series, (A)
money in an amount, or (B) U.S. Government Obligations which through the
scheduled payment of principal and interest in respect thereof in accordance
with their terms and without further reinvestment thereof will provide, not
later than one day before the due date of any payment, money in an amount, or
(C) a combination thereof in an aggregate amount, sufficient, in the opinion of
a nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay and discharge,
and which shall be applied by the Trustee or other qualifying trustee to pay and
discharge, the 


   72



principal of and premium, if any, on and each installment of interest on the
Securities on the Stated Maturity of such principal or installment of interest
on the day on which such payments are due and payable in accordance with the
terms of this Indenture and of such Securities. For this purpose, "U.S.
Government Obligations" means securities that are (x) direct obligations of the
United States of America for the payment of which its full faith and credit is
pledged or (y) obligations of a Person controlled or supervised by and acting as
an agency or instrumentality of the United States of America the payment of
which is unconditionally guaranteed as a full faith and credit obligation by the
United States of America, which, in either case, are not callable or redeemable
at the option of the issuer thereof, and shall also include a depository receipt
issued by a bank (as defined in Section 3(a)(2) of the Securities Act of 1933,
as amended) as custodian with respect to any such U.S. Government Obligation or
a specific payment of principal of or interest on any such U.S. Government
Obligation held by such custodian for the account of the holder of such
depository receipt; provided that (except as required by law) such custodian is
not authorized to make any deduction from the amount payable to the holder of
such depository receipt from any amount received by the custodian in respect of
the U.S. Government Obligation or the specific payment of principal of or
interest on the U.S. Government Obligation evidenced by such depository receipt.

          (2) In the case of an election under Section 1402, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (x) the Company
has received from, or there has been published by, the Internal Revenue Service
a ruling or (y) since the date of this Indenture there has been a change in the
applicable federal income tax law, in either case to the effect that, and based
thereon such opinion shall confirm that, the Holders of the Outstanding
Securities of such series will not recognize income, gain or loss for federal
income tax purposes as a result of such deposit, Defeasance and discharge and
will be subject to federal income tax on the same amounts, in the same manner
and at the same times as would have been the case if such Defeasance had not
occurred.

          (3) In the case of an election under Section 1403, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of the Outstanding Securities of such series will not recognize gain or
loss for federal income tax purposes as a result of such Covenant Defeasance and
will be subject to federal income tax on the same amounts, in the same manner
and at the same times as would have been the case if such deposit and Covenant
Defeasance had not occurred.

          (4) The Company shall have delivered to the Trustee an Officers'
Certificate to the effect that the Securities, if then listed on any securities
exchange, will not be delisted as a result of such deposit, in the case of an
election under Section 1402 or 1403.

          (5) No Event of Default or event which with notice or lapse of time or
both would become an Event of Default shall have occurred and be continuing on
the date of such deposit or, insofar as subsection (6) are concerned, at any
time during the period ending on the 90th day after the date of such deposit (it
being understood that this condition shall not be deemed satisfied until the
expiration of such period).

   73



          (6) Such Defeasance or Covenant Defeasance shall not cause the Trustee
to have a conflicting interest as defined in Section 608 and for purposes of the
Trust Indenture Act with respect to any securities of the Company (assuming all
Securities are in default within the meaning of such Act).

          (7) Such Defeasance or Covenant Defeasance shall not result in a
breach or violation of, or constitute a default under, any other agreement or
instrument to which the Company is a party or by which it is bound.

          (8) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for relating to either the Defeasance under Section 1402 or
the Covenant Defeasance under Section 1403 (as the case may be) have been
complied with.

          (9) Such Defeasance or Covenant Defeasance shall not result in the
trust arising from such deposit to constitute, unless it is qualified as or
exempt from, a regulated investment company under the Investment Company Act of
1940, as amended.

SECTION 1405.  Deposited Money and U.S. Government Obligations to be Held in 
               Trust; Other Miscellaneous Provisions.

      Subject to the provisions of the last paragraph of Section 1003, all money
and U.S. Government Obligations (including the proceeds thereof) deposited with
the Trustee (or other qualifying trustee -- collectively, for purposes of this
Section 1405, the "Trustee") pursuant to Section 1404 in respect of the
Securities of any Defeasible Series shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities, of all sums due and to become due
thereon, in respect of principal (and premium, if any) and interest, but such
money need not be segregated from other funds except to the extent required by
law. Money so held in trust, to the extent allocated for the payment of
Securities, shall not be subject to the provisions of Article Fourteen.

      The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1404 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of the Outstanding Securities.

      Anything in this Article Fourteen to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 1404 with respect to Securities of any Defeasible Series that, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount hereof which would then be required to be deposited to
effect an equivalent Defeasance or Covenant Defeasance with respect to the
Securities of such series.

SECTION 1406.   Reinstatement.

      If the Trustee or Paying Agent is unable to apply any money 


   74


in accordance with Section 1402 or 1403 by reason of any order or judgment of
any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, the Company's obligations under this Indenture and
the Securities shall be revived and reinstated as though no deposit had occurred
pursuant to this Article Fourteen until such time as the Trustee or Paying Agent
is permitted to apply all such money in accordance with Section 1402 or 1403;
provided, however, that if the Company makes any payment of principal of (or
premium or Make-Whole Amount, if any) or interest on any Security following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the money held by
the Trustee or Paying Agent.

      This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

SECTION 1407.   Securities Redeemed in Part.

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

                                 ARTICLE FIFTEEN

                                  SINKING FUNDS

SECTION 1501.   Applicability of Article.

      The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.

      The minimum amount of any sinking fund payment provided for by the terms
of Securities of any series is herein referred to as a "mandatory sinking fund
payment", and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment". If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided
in Section 1502. Each sinking fund payment shall be applied to the redemption of
Securities of any series as provided for by the terms of Securities of such
series.

SECTION 1502.   Satisfaction of Sinking Fund Payments with Securities.

      The Company (1) may deliver Outstanding Securities of a series (other than
any previously called for redemption) and (2) may apply as a credit Securities
of a series which have been converted pursuant to Article Fourteen or which have
been redeemed 


   75



either at the election of the Company pursuant to the terms of such Securities
or through the application of permitted optional sinking fund payments pursuant
to the terms of such Securities, in each case in satisfaction of all or any part
of any sinking fund payment with respect to the Securities of such series
required to be made pursuant to the terms of such Securities as provided for by
the terms of such series; provided that such Securities have not been previously
so credited. Such Securities shall be received and credited for such purpose by
the Trustee at the Redemption Price specified in such Securities for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly. 

SECTION 1503. Redemption of Securities for Sinking Fund.

      Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 1202 and will also deliver to the Trustee any Securities to
be so delivered. Not less than 30 days before each such sinking fund payment
date the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 1103 and cause notice of
the redemption thereof to be given in the name of and at the expense of the
Company in the manner provided in Section 1104. Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Sections 1106 and 1107.

      This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

      IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be
duly executed, and their respective corporate seals to be hereunto affixed and
attested, all as of the day and year first above written.
