other action provided or permitted by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; 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

9

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

 

affidavit shall also constitute sufficient proof of his authority. The fact and

Person executing the same, may also be proved in any other manner which the
Trustee deems sufficient.

     Any request, demand, authorization, direction, notice, consent, waiver or
other Act of the Holder of any Security shall bind every future Holder of the

anything done, omitted or suffered to be done by the Trustee or the Company in

Security.
     The Company may, in the circumstances 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 new 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 the provisions
of this paragraph shall not apply with respect to, any notice, declaration,
request or direction referred to in the next paragraph.
     The Trustee may set any day as a record date for the purpose of determining
the Holders of Outstanding Securities of any series entitled to join in the
giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 5.02, 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, (iii) any request to institute
proceedings referred to in Section 5.07(2) or (iv) any direction referred to in
Section 5.12, in each case with respect to Securities of such series. Promptly
after any record date is set pursuant to this paragraph, the Trustee shall
notify the Company and the Holders of Outstanding Series of such series of any

10

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

 

such record date so fixed and the proposed action. 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,
request or direction, whether or not such Holders remain Holders after such
record date; provided that, unless such notice, declaration, request 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, request 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, request or direction contrary to
or different from, or, after the expiration of such period, identical to, the
notice, declaration, request or direction to which such record date relates, in
which event the Trustee may set a new record date in respect thereof pursuant to
this paragraph. Nothing in this paragraph shall be construed to render
ineffective any notice, declaration, request 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, request 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 1.06 Notices, Etc., to Trustee, Company.
     Any request, demand, authorization, direction, notice, consent, waiver or
Act of Holders or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with,
          (1) the Trustee by any Holder or by the Company shall be sufficient
for every purpose hereunder if made, given, furnished or filed in writing (via
facsimile or first class mail, postage prepaid) to or with the Trustee at its
Corporate Trust Office, or
          (2) the Company by the Trustee or by any Holder shall be sufficient
for every purpose hereunder (unless otherwise herein expressly provided) if in

instrument or at any other address previously furnished in writing to the
Trustee by the Company.

notice to Holders of any event, such notice shall be sufficiently given (unless

or 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 (if any), and not earlier than the earliest date (if any), prescribed for
the giving of such notice. In any case where notice to Holders is given by mail,
neither the failure to mail

11

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

 

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 the acknowledgement of
receipt 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.
     Section 1.08 Conflict with Trust Indenture Act. If any provision hereof
limits, qualifies or conflicts with a provision of the Trust Indenture Act that
is required under such Act to be a part of and govern this Indenture, the latter
provision shall control. If any provision of this Indenture modifies or excludes
any provision of the Trust Indenture Act that may be so modified or excluded,
the latter provision shall be deemed to apply to this Indenture as so modified

Indenture by the Company shall bind its successors and assigns, whether so
expressed or not.

Section)) payment of interest or principal (and premium, if any) or conversion
of the Securities need not be made at such Place of Payment on such date, but

thereto reference is hereby made for a statement of the respective rights,
limitations of rights, duties and immunities thereunder of the Company, the
Trustee and the Holders of the Securities and of the terms upon which the
Securities are, and are to be, authenticated and delivered. This Security is one
of the series designated on the face hereof [if applicable, insert —, limited in
aggregate principal amount to $                     ].
     [If applicable, insert — Subject to and upon compliance with the provisions
of the Indenture, the Holder of this Security is entitled, at his option, at any
time on or before the close of business on                     , or in case this
Security or a portion hereof is called for redemption, then in respect of this
Security or such portion hereof until and including, but (unless the Company
defaults in making the payment due upon redemption) not after, the close of

Security (or any portion of the principal amount hereof which is $1,000 or an
integral multiple thereof), at the principal amount hereof, or of such portion,
into fully paid and non-assessable shares (calculated as to each conversion to
the nearest 1/100 of a share) of Common Stock of the Company at a conversion
price per share of Common Stock equal to $                     per each share of
Common Stock (or at the current adjusted conversion price if an adjustment has

Date to the opening of business on such Interest Payment Date (unless this
Security or the portion thereof being converted has been called for redemption
on a Redemption Date within such period), also accompanied by payment in funds
acceptable to the Company of an amount equal to the interest payable on such
Interest Payment Date on the principal amount of this Security then being
converted. Subject to the aforesaid requirement for payment and, in the case of
a conversion after the Regular Record Date next preceding any Interest Payment
Date and on or before such Interest Payment Date, to the right of the Holder of
this Security (or any Predecessor Security) of record at such Regular Record
Date to receive an installment of interest (with certain exceptions provided in
the Indenture), no payment or adjustment is to be made on conversion for
interest accrued hereon or for dividends on the Common Stock issued on
conversion. No fractions of shares or scrip representing fractions of shares
will be issued on conversion, but instead of any fractional interest the Company
shall pay a cash adjustment as provided in the Indenture. The conversion price
is subject to adjustment as provided in the Indenture. In addition, the
Indenture provides that in case of certain consolidations or mergers to which
the Company is a party or the transfer of substantially all of the assets of the
Company, the Indenture shall be amended, without the consent of any Holders of
Securities, so that this Security, if then outstanding, will be convertible
thereafter, during the period this Security shall be convertible as specified
above, only into the kind and amount of securities, cash and other property
receivable upon the consolidation, merger or transfer by a holder of the number
of shares of Common Stock into which this Security might have been converted
immediately prior to such consolidation, merger or transfer (assuming such
holder of Common Stock failed to exercise any rights of election and received
per share the kind and amount received per share by a plurality of non-electing
shares).]

without the consent of the Holders, create and issue pursuant to this Indenture
additional securities of any series of Securities (“Add On Securities”) having
terms and conditions identical to those of such series of Outstanding
Securities, except that such Add On Securities:
               (A) may have a different issue date from such series of

Vice Chairmen or one of its Vice Presidents. 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

24

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

 

individuals or any of them have ceased to hold such offices prior to the
authentication and delivery of such Securities or did not hold such offices at
the date of such Securities.
     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any Series executed by the
Company, together with a Company Order for the authentication and delivery of
such Securities, and the Trustee in accordance with the Company Order shall
authenticate and deliver such Securities. If the form or terms of the Securities
of the series have been established in or pursuant to one or more Board
Resolutions as permitted by Sections 2.01 and 3.01, in authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities, the Trustee shall be entitled to receive, and
(subject to Section 6.01) 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 2.01, 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 3.01, 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 reasonably acceptable to the Trustee.
     Notwithstanding the provisions of Section 3.01 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 Officer’s Certificate otherwise
required pursuant to Section 3.01 or the 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. Notwithstanding the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the

25

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

 

Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 3.09, for all purposes of this Indenture
such Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.
     Section 3.04 Temporary Securities. Pending the preparation of definitive
Securities of any series, the Company may execute, and upon Company Order the
Trustee shall authenticate and deliver, temporary Securities which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities in lieu of
which they are issued 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.
     If temporary Securities of any series are issued, the Company will cause
definitive Securities of that series to be prepared without unreasonable delay.
After the preparation of definitive Securities of such series, the temporary
Securities of such series shall be exchangeable for definitive Securities of
such series upon surrender of the temporary Securities of such series at the
office or agency of the Company in a Place of Payment for that series, without
charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities of any series the Company shall execute and the Trustee
shall authenticate and deliver in exchange therefor one or more definitive
Securities of the same series, of any authorized denominations and of a like
aggregate principal amount. Until so exchanged, the temporary Securities of any
series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of such series and tenor.
     Section 3.05 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 of the Company in a Place of Payment being herein sometimes collectively
referred to as the “Security Register”) in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration
of Securities and of transfers of Securities. The Trustee is hereby appointed
“Security Registrar” for the purpose of registering Securities and transfers of
Securities as herein provided.
     Upon surrender for registration of transfer of any Security of any series
at the office or agency in a Place of Payment for that series, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities of the same
series, of any authorized denominations and of a like tenor and aggregate
principal amount.
     At the option of the Holder, Securities of any series may be exchanged for
other Securities of the same series, of any authorized denominations and of a
like tenor and 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.

26

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

 

     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 or Security Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any registration of transfer or exchange of
Securities, other than exchanges pursuant to Section 3.04 or 9.06 not involving
any transfer.
     The Company shall not be required (1) to issue, register the transfer of or
exchange Securities of any series during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section 11.03 and ending
at the close of business on the day of such mailing, or (2) to register the
transfer of or exchange any Security so selected for redemption in whole or in
part, except the unredeemed portion of any Security being redeemed in part.
     The provisions of Clauses (1), (2), (3) and (4) below shall apply only to
Global Securities:
          (1) Each Global Security authenticated under this Indenture shall be
registered in the name of the Depositary designated for such Global Security or
a nominee thereof and delivered to such Depositary or a nominee thereof or
custodian therefor, and each such Global Security shall constitute a single
Security for all purposes of this Indenture.
          (2) Notwithstanding any other provision in this Indenture, and subject
to such applicable provisions, if any, as may be specified as contemplated by
Section 3.01, no Global Security may be exchanged in whole or in part for
Securities registered, and no transfer of a Global Security in whole or in part
may be registered, in the name of any Person other than the Depositary for such
Global Security or a nominee thereof unless (A) such Depositary has notified the
Company that it is unwilling or unable or no longer permitted under applicable
law to continue as Depositary for such Global Security and the Company has not
appointed a successor within 90 days of receipt of such notice or (B) there
shall have occurred and be continuing an Event of Default with respect to such
Global Security or (C) the Company so directs the Trustee by Company Order or
(D) there shall exist such circumstances, if any, in addition to or in lieu of
the foregoing as have been specified for this purpose as contemplated by
Section 3.01.
          (3) Subject to Clause (2) above and to such applicable provisions, if
any, as may be specified as contemplated by Section 3.01, any exchange of a
Global Security for other Securities may be made in whole or in part, and all
Securities issued in exchange for a Global

27

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

 

Security or any portion thereof shall be registered in such names as the
Depositary for such Global Security shall direct.
          (4) Every Security authenticated and delivered upon registration of
transfer of, or in exchange for or in lieu of, a Global Security or any portion
thereof, whether pursuant to this Section, Section 3.04, 3.06 or 9.06 or
otherwise, shall be authenticated and delivered in the form of, and shall be, a
Global Security, unless such Security is registered in the name of a Person
other than the Depositary for such Global Security or a nominee thereof.
     Section 3.06 Mutilated, Destroyed, Lost and Stolen Securities. If any
mutilated Security is surrendered to the Trustee, the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a new Security
of the same series and of like tenor and principal amount and bearing a number
not contemporaneously outstanding.
     If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security and
(ii) such security or indemnity as may be required by them to save each of them
and any agent of 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 the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security, a new Security
of the same series and of like tenor and principal amount and bearing a number
not contemporaneously outstanding.
     In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.
     Upon the issuance of any new Security under this Section, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee and counsel to the Trustee) in connection
therewith.
     Every new Security of any series issued pursuant to this Section in
exchange for any mutilated Security or in lieu of any destroyed, lost or stolen
Security shall constitute an original additional contractual obligation of the
Company, whether or not the mutilated, destroyed, lost or stolen Security shall
be at any time enforceable by anyone, and shall be entitled to all the benefits
of this Indenture equally and proportionately with any and all other Securities
of that series duly issued hereunder.
     The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.
     Section 3.07 Payment of Interest; Interest Rights Preserved. Except as
otherwise provided as contemplated by Section 3.01 with respect to any series of
Securities, 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.

28

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

 

     Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called “Defaulted Interest”) shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:
          (1) The Company may elect to make payment of any Defaulted Interest to
the Persons in whose names the Securities of such series (or their respective
Predecessor Securities) are registered at the close of business on a Special
Record Date for the payment of such 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 of such series
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 not less
than 10 days prior to the date of the proposed payment and not less than 10 days
after the receipt by the Trustee of the notice of the proposed payment. The
Trustee shall promptly notify the Company of such Special Record Date and, in
the name and at the expense of the Company, shall cause notice of the proposed
payment of such Defaulted Interest and the Special Record Date therefor to be
delivered electronically or mailed, first-class postage prepaid, to each Holder
of Securities of such series at his address as it appears in the Security
Register, not less than 10 days prior to such Special Record Date. Notice of the
proposed payment of such Defaulted Interest and the Special Record Date therefor
having been so delivered or mailed, such Defaulted Interest shall be paid to the
Persons in whose names the Securities of such series (or their respective
Predecessor Securities) are registered at the close of business on such Special
Record Date and shall no longer be payable pursuant to the following Clause (2).
          (2) The Company may make payment of any Defaulted Interest on the
Securities of any series in any other lawful manner not inconsistent with the
requirements of any securities exchange on which such Securities may be listed,
and upon such notice as may be required by such exchange, if, after written
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.
     Subject to the provisions of Section 14.02, 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, 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

29

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

 

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 3.08 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 any premium and (subject to Section 3.07) any interest on such
Security and for all other purposes whatsoever, whether or not such Security be
overdue, and neither the Company, the Trustee nor any agent of the Company or
the Trustee shall be affected by notice to the contrary.
     Section 3.09 Cancellation. All Securities surrendered for payment,
redemption, registration of transfer or exchange or conversion or for credit
against any sinking fund payment shall, if surrendered to any Person other than
the Trustee, be delivered to the Trustee and shall be promptly cancelled by it.
The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and may deliver to the Trustee (or
to any other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold,
and all Securities so delivered shall, at the written direction of the Company,
be promptly cancelled by the Trustee. No Securities shall be authenticated in
lieu of or in exchange for any Securities cancelled as provided in this Section,
except as expressly permitted by this Indenture. All cancelled Securities held
by the Trustee shall be disposed of by the Trustee in its customary manner.
     Section 3.10 Computation of Interest. Except as otherwise specified as
contemplated by Section 3.01 for Securities of any series, interest on the
Securities of each series shall be computed on the basis of a 360-day year of
twelve 30-day months.
     Section 3.11 CUSIP Numbers. The Company in issuing the Securities may use
“CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use
“CUSIP” numbers in notices of redemption as a convenience to Holders; provided
that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Securities or as contained
in any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Securities, and any such redemption shall
not be affected by any defect in or omission of such numbers. The Company will
promptly notify the Trustee in writing of any changes in the “CUSIP” numbers.
ARTICLE IV
SATISFACTION AND DISCHARGE
     Section 4.01 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 herein
expressly provided for), and the Trustee, at the expense of the Company, shall
execute proper instruments acknowledging satisfaction and

30

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

to the Trustee), when
          (1) either

than (i) Securities which have been destroyed, lost or stolen and which have
been replaced or paid as provided in Section 3.06 and (ii) Securities for whose
payment money has theretofore been deposited in trust or segregated and held in
trust by the Company and thereafter repaid to the Company or discharged from
such trust) have been delivered to the Trustee for cancellation; or
             (B) all such Securities not theretofore delivered to the Trustee
for cancellation;

  (i)   have become due and payable, or     (ii)   will become due and payable
at their Stated Maturity within one year, or     (iii)   are to be called for
redemption within one year under arrangements satisfactory to the Trustee for
the giving of notice of redemption by the Trustee in the name, and at the
expense, of the Company,

and the Company, in the case of (i), (ii) or (iii) above, has deposited or
caused to be deposited with the Trustee as trust funds in trust for the purpose
an amount sufficient to pay and discharge the entire indebtedness on such
Securities not theretofore delivered to the Trustee for cancellation, for
principal and any premium and interest to the date of such deposit (in the case
of Securities which have become due and payable) or to the Stated Maturity or
Redemption Date, as the case may be;
          (2) the Company has paid or caused to be paid all other sums payable
hereunder by the Company; and
          (3) the Company has delivered to the Trustee an Officer’s Certificate
and an Opinion of Counsel, each stating that all conditions precedent herein
provided for relating to the satisfaction and discharge of this Indenture have
been complied with.
     Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.06, and, if money
shall have been deposited with the Trustee pursuant to subclause (B) of Clause
(1) of this Section, the obligations of the Trustee under Section 4.02, shall
survive such satisfaction and discharge.
     Section 4.02 Application of Trust Money. All money deposited with the
Trustee pursuant to Section 4.01 shall be held in trust and applied by it, in
accordance with the provisions of the 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 any premium and interest for whose
payment such money has been deposited with the Trustee. All money deposited with
the Trustee pursuant to

31

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

 

Section 4.01 (and held by it or any Paying Agent) for payment of Securities of a
series that is convertible in accordance with Article XIV and that are
subsequently converted, shall be returned to the Company.
ARTICLE V

     Section 5.01 Events of Default. “Event of Default”, wherever used herein
with respect to Securities of any series, means any one of the following events
(whatever the reason for such Event of Default and whether it shall 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) a default in any payment of interest on any Security of that
series when due and payable and such default continues for 30 days;
          (2) a default in the payment of principal of any Security in that
series when due and payable at its Stated Maturity, upon optional redemption,

otherwise;
          (3) a default in the deposit of any sinking fund payment, when and as
due by the terms of a Security of that series;
          (4) (i) a default in the observance or performance of Article VIII or

(2) or (3) above or (b) any covenant or warranty a default in whose performance
or whose breach has expressly been included in this Indenture solely for the
benefit of series of Securities other than that series) which default under this
clause (ii) continues for a period of 60 days after the Company receives written
notice specifying the default (and demanding that such default be remedied) from
the Trustee or the Holders of at least 25% in principal amount of the
Outstanding Securities of that series;
          (5) the failure to pay at final stated maturity (giving effect to any
applicable grace periods and any extensions thereof) the principal amount of any
Indebtedness of the Company, or the acceleration of the final stated maturity of
any such Indebtedness (which acceleration is not rescinded, annulled or
otherwise cured within 30 days of receipt by the Company of notice of any such
acceleration) if the aggregate principal amount of such Indebtedness, together
with the principal amount of any other such Indebtedness in default for failure
to pay principal at final maturity or which has been accelerated (in each case
with respect to which the 30-day period described above has elapsed), aggregates
$50 million or more at any time;
          (6) the Company or any Significant Subsidiary pursuant to or within
the meaning of any Bankruptcy Law:
               (A) commences a voluntary case;

32

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

 

               (B) consents to the entry of an order for relief against it in an
involuntary case;
               (C) consents to the appointment of a Custodian of it or for any
substantial part of its property;
               (D) makes a general assignment for the benefit of its creditors;
or takes any comparable action under any foreign laws relating to insolvency; or
               (E) takes any corporate action to authorize or effect any of the
foregoing;
          (7) a court of competent jurisdiction enters an order or decree under
any Bankruptcy Law:
               (A) that is for relief against the Company or any Significant
Subsidiary in an involuntary case;
               (B) appoints a Custodian of the Company or any Significant
Subsidiary or for any substantial part of its property; or
               (C) orders the winding up or liquidation of the Company or any
Significant Subsidiary;
and such order or decree remains unstayed and in effect for 60 days; or
          (8) the rendering of any judgment or decree for the payment of money
in excess of $50 million or its foreign currency equivalent against the Company
or a Significant Subsidiary if:
               (A) an enforcement proceeding thereon is commenced by any
creditor, or
               (B) such judgment or decree remains outstanding for a period of
60 days after such judgment becomes final and not appealable and is not
discharged, paid, waived or stayed (the “judgment default provision”).
     The Company shall deliver to the Trustee, within 30 days after the
occurrence thereof, written notice in the form of an Officers’ Certificate of
any event which is, or with the giving of notice or the lapse of time or both
would become, an Event of Default, its status and what action the Company is
taking or proposes to take with respect thereto.
     Section 5.02 Acceleration of Maturity; Rescission and Annulment. If an
Event of Default (other than an Event of Default specified in Section 5.01(6) or
5.01(7) with respect to the Company) and with respect to Securities of any
series at the time Outstanding occurs and is continuing, then in every such case
the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series may declare the principal amount (or, if
any of the Securities of that series are Original Issue Discount Securities,
such portion of the

33

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

 

principal amount of such Securities as may be specified in the terms thereof)
and unpaid interest of all of the Securities of that series to be due and
payable immediately, by a notice in writing to the Company (and to the Trustee
if given by Holders), and upon any such declaration such principal amount (or
specified amount) shall become immediately due and payable. If an Event of
Default specified in Section 5.01(6) or 5.01(7) with respect to the Company 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 of the
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) and unpaid interest shall automatically, and without any declaration or
other action on the part of the Trustee or any Holder, become immediately due
and payable.
     At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if:
          (1) the Company has paid or deposited with the Trustee a sum
sufficient to pay:
               (A) all overdue interest on all Securities of that series,
               (B) the principal of (and premium, if any, on) any Securities of
that series which have become due otherwise than by such declaration of
acceleration and any interest thereon at the rate or rates prescribed therefor
in such Securities,
               (C) to the extent that payment of such interest is lawful,
interest upon overdue interest at the rate or rates prescribed therefor in such
Securities, and
               (D) all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel; and
          (2) all Events of Default with respect to Securities of that series,
other than the non-payment of the principal of Securities of that series which
have become due solely by such declaration of acceleration, have been cured or
waived as provided in Section 5.13.
No such rescission or annulment shall affect any subsequent default or impair
any right consequent thereon.
     Section 5.03 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, if
any, on) any Security at the Maturity thereof,

34

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

 

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 any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium 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 for an express trust, may institute a
judicial proceeding for the collection of the sum so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or other obligor upon the Securities of that series and
collect the monies adjudged or decreed to be payable in the manner provided by
law out of the property of the Company or any other obligor upon the Securities
of that series, wherever situated.
     If an Event of Default with respect to Securities of any series occurs and
is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series by such
appropriate judicial proceedings as the Trustee shall deem necessary to protect
and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in this Indenture or in aid of the exercise of any power
granted herein, or to enforce any other proper remedy.
     Section 5.04 Trustee May File Proofs of Claim. In case of any judicial
proceeding relative to the Company (or any other obligor upon the Securities),
or any of the property or creditors of the Company (or any other obligor upon
the Securities), the Trustee shall be entitled and empowered, by intervention in
such proceeding or otherwise, to take any and all actions authorized under the
Trust Indenture Act in order to have claims of the Holders and the Trustee
allowed in any such proceeding. In particular, the Trustee shall be authorized
to collect and receive any moneys or other property payable or deliverable on
any such claims and to distribute the same; and any custodian, receiver,
assignee, trustee, liquidator, sequestrator or other similar official in any
such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 6.06.
     No provision of this Indenture 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; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors’ or
other similar committee.
     Section 5.05 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

35

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

 

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.
     Section 5.06 Application of Money Collected. 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 any premium 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 6.06;
     SECOND: To the payment of the amounts then due and unpaid for principal of
and any premium 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 any premium and interest, respectively; and
     THIRD: To the Company.
     Section 5.07 Limitation on Suits. No Holder of any Security of any series
shall have any right to institute any proceeding, judicial or otherwise, with
respect to this Indenture, or for the appointment of a receiver or trustee, or
for any other remedy hereunder, unless:
          (1) such Holder has previously given written notice to the Trustee of
a continuing Event of Default with respect to the Securities of that series;
          (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 satisfactory to it against the costs, expenses and liabilities to be
incurred in compliance with such request;
          (4) the Trustee for 60 days after its receipt of such notice, request
and offer of indemnity has failed to institute any such proceeding; and
          (5) no direction inconsistent with such written request has been given
to the Trustee during such 60-day period by the Holders of a majority in
principal amount of the Outstanding Securities of that series;
it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or

36

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

 

preference over any other of such Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal and ratable
benefit of all of such Holders.
     Section 5.08 Unconditional Right of Holders to Receive 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 any premium and
(subject to Section 3.07) 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 XIV 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 5.09 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 5.10 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 3.06, 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 5.11 Delay or Omission Not Waiver. No delay or omission of the
Trustee or of any Holder of any Securities 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 5.12 Control by Holders. The Holders of a majority in principal
amount of the Outstanding Securities of any series shall have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee, or exercising any trust or power conferred on the
Trustee, with respect to the Securities of such series, provided that:
          (1) such direction shall not be in conflict with any rule of law or
with this Indenture,
          (2) the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction, and

37

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

 

          (3) subject to the provisions of Section 6.01, the Trustee shall have
the right to decline to follow any such direction if the Trustee in good faith
shall, by a Responsible Officer or Officers of the Trustee, determine that the
proceedings so directed would involve the Trustee in personal liability.
     Section 5.13 Waiver of Past Defaults. The Holders of not less than a
majority in principal amount of the Outstanding Securities of any series may on
behalf of the Holders of all the Securities of such series waive any past
default hereunder with respect to such series and its consequences, except a
default:
          (1) in the payment of the principal of or any premium or interest on
any Security of such series, or
          (2) in respect of a covenant or provision hereof which under
Article IX cannot be modified or amended without the consent of the Holder of
each Outstanding Security of such series affected.
     Upon any such waiver, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.
     Section 5.14 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 apply to any suit instituted by the
Trustee, to any suit instituted by any Holders of the Securities, or group of
Holders of the Securities, holding in the aggregate more than 10% of principal
amount of the Outstanding Securities of any series, or to any suit instituted by
any Holder of the Outstanding Securities for the enforcement of the payment of
principal of or any premium or interest on any Outstanding Securities held by
such Holder, on or after the respective Stated Maturities expressed in such
Outstanding Securities, and provided, further, 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 the Trustee or, if applicable, in any suit for the enforcement of the right
to convert any Security in accordance with Article XIV.
     Section 5.15 Waiver of Usury, 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 usury, stay or extension law wherever enacted, now or at any
time hereafter in force, which may affect the covenants or the performance of
this Indenture; and the Company (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 VI
THE TRUSTEE
     The Trustee hereby accepts the trust imposed upon it by this Indenture and
covenants and agrees to perform the same, as herein expressed.
     Section 6.01 Duties of Trustee.
     (a) If an Event of Default has occurred and is continuing, the Trustee
shall exercise such of the rights and powers vested in it by this Indenture and
use the same degree of care and skill in their exercise as a prudent person
would exercise or use under the circumstances in the conduct of his own affairs.
     (b) Except during the continuance of an Event of Default:
          (1) The Trustee need perform only those duties as are specifically set
forth in this Indenture and no others, and no covenants or obligations shall be
implied in or read into this Indenture.
          (2) In the absence of bad faith on its part, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon certificates or opinions furnished to the
Trustee and conforming to the requirements of this Indenture. However, the
Trustee shall examine the certificates and opinions to determine whether or not

funds or indemnity satisfactory to it against such risk or liability is not
reasonably assured to it.

     (j) In no event shall the Trustee be responsible or liable for special,

action.
     (k) The Trustee may request that the Company deliver a certificate setting
forth the names of individuals and/or titles of officers authorized at such time
to take specified actions pursuant to this Indenture.
     Section 6.03 Individual Rights of Trustee. The Trustee in its individual or
any other capacity may become the owner or pledgee of Securities and may
otherwise deal with the Company or its Affiliates with the same rights it would
have if it were not Trustee. Any Paying Agent or Security Registrar may do the
same with like rights. However, the Trustee must comply with Sections 6.09 and
6.10.
     Section 6.04 Trustee’s Disclaimer. The Trustee shall not be responsible for
and makes no representation as to the validity or adequacy of this Indenture or
the Securities, it shall not be accountable for the Company’s use of the
proceeds from the Securities, and it shall not be responsible for any statement

     Section 6.05 Notice of Default. If an Event of Default with respect to
Securities of any series occurs and is continuing and if it is known to the
Trustee, the Trustee shall deliver to each Holder of Securities of such series
notice of the uncured Event of Default (hereinafter called a “Notice of

of an Event of Default in payment of principal (or premium, if any) of, or
interest on, any Security (including payments pursuant to the mandatory

Securities of such series.
     Section 6.06 Compensation and Indemnity. The Company shall pay to the

the Trustee shall from time to time agree in writing. The Trustee’s compensation

trust. The Company shall reimburse the Trustee upon

41

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

agents, accountants, experts and counsel.
     The Company shall indemnify the Trustee against any and all loss,
liability, claim, damage or expense (including reasonable attorneys’ fees and
expenses), including taxes (other than taxes based on the income of the
Trustee), incurred by or in connection with the acceptance or administration of
this trust and the performance of its duties hereunder, including the costs and
expense of enforcing this Indenture against the Company (including this
Section 6.06) and defending itself against any claim (whether asserted by the
Company, any Holder or any other person) or liability in connection with the
exercise or performance of any of its rights, powers or duties hereunder. The
Trustee shall notify the Company of any claim for which it may seek indemnity
promptly upon obtaining actual knowledge thereof; provided, however, that any
failure so to notify the Company shall not relieve the Company of its indemnity
obligations hereunder. The Company need not reimburse any expense or indemnify
against any loss, liability or expense incurred by the Trustee through the
Trustee’s own willful misconduct, negligence or bad faith.
     To secure the Company’s payment obligations in this Section 6.06, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee other than money or property held in trust to pay
principal of and interest on particular Securities.
     The Company’s payment obligations pursuant to this Section 6.06 shall
survive the satisfaction or discharge of this Indenture, any rejection or
termination of this Indenture under any bankruptcy law or the resignation or
removal of the Trustee. Without prejudice to any other rights available to the
Trustee under applicable law, when the Trustee incurs expenses after the
occurrence of an Event of Default specified in Section 5.01(6) or (7) with
respect to the Company, the expenses are intended to constitute expenses of
administration under the Bankruptcy Law.
     Section 6.07 Replacement of Trustee. The Trustee may resign at any time
with respect to the Securities of one or more series by so notifying the Company
in writing. The Holder or Holders of a majority in principal amount of the
Outstanding Securities of a series may remove the Trustee with respect to
Securities of such series by so notifying the Company and the Trustee in writing
and may appoint a successor trustee with respect to Securities of such series
with the Company’s consent. The Company may remove the Trustee if:
          (1) the Trustee fails to comply with Section 6.09;
          (2) the Trustee is adjudged bankrupt or insolvent;
          (3) a receiver, custodian, or other public officer takes charge of the
Trustee or its property; or
          (4) the Trustee becomes incapable of acting.

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

 

     With respect to the Securities of one or more series, if the Trustee
resigns, is removed by the Company or by the Holders of a majority in principal
amount of the Outstanding Securities of that series and such Holders do not
reasonably promptly appoint a successor Trustee, or if a vacancy exists in the
office of Trustee for any reason (the Trustee in such event being referred to
herein as the retiring Trustee), the Company shall promptly appoint a successor
Trustee, with respect to Securities of that or those series.
     A successor Trustee shall deliver a written acceptance of its appointment
to the retiring Trustee and to the Company. Thereupon the resignation or removal
of the retiring Trustee shall become effective, and the successor Trustee shall
have all the rights, powers and duties of the Trustee under this Indenture with
respect to such series of Securities. The successor Trustee shall mail a notice
of its succession to each Holder of Securities of that or those series. The
retiring Trustee shall promptly transfer all property held by it as Trustee with
respect to such series of Securities to the successor Trustee, subject to the
lien provided for in Section 6.06.
     If a successor Trustee with respect to a series of Securities does not take
office within 60 days after the retiring Trustee resigns or is removed, the
retiring Trustee (at the Company’s expense), the Company or the Holder or
Holders of at least 10% in principal amount of the Outstanding Securities of
that series may petition at the expense of the Company any court of competent
jurisdiction for the appointment of a successor Trustee with respect to such
series.
     If the Trustee fails to comply with Section 6.09, unless the Trustee’s duty
to resign is stayed as provided in Trust Indenture Act Section 310(b), any
Holder who has been a bona fide holder of Securities of a series for at least
six months may petition any court of competent jurisdiction for the removal of
the Trustee with respect to such series and the appointment of a successor
Trustee with respect to such series.
     Notwithstanding replacement of the Trustee pursuant to this Section 6.07,
the Company’s obligations under Section 6.06 shall continue for the benefit of
the retiring Trustee.
     Section 6.08 Successor Trustee by Merger, Etc. If the Trustee consolidates
with, merges or converts into, or transfers all or substantially all of its
corporate trust business to, another corporation or banking association, the
resulting, surviving or transferee corporation without any further act shall, if
such resulting, surviving or transferee corporation is otherwise eligible
hereunder, be the successor Trustee.
     In case at the time such successor or successors by merger, conversion or
consolidation to the Trustee shall succeed to the trusts created by this
Indenture any of the Securities shall have been authenticated but not delivered,
any such successor to the Trustee may adopt the certificate of authentication of
any predecessor trustee, and deliver such Securities so authenticated; and in
case at that time any of the Securities shall not have been authenticated, any
successor to the Trustee may authenticate such Securities either in the name of
any predecessor hereunder or in the name of the successor to the Trustee; and in
all such cases such certificates shall have the full force which it is anywhere
in the Securities or in this Indenture provided that the certificate of the
Trustee shall have.

Section 310(b)(1) any indenture or indentures under which other securities or
certificates of interest or participation in other securities of the Company are
outstanding if the requirements for such exclusion set forth in Trust Indenture
Act Section 310(b)(1) are met.
     Section 6.10 Preferential Collection of Claims against Company. The Trustee
shall comply with Trust Indenture Act Section 311(a), excluding any creditor
relationship listed in Trust Indenture Act Section 311(b). A Trustee who has
resigned or been removed shall be subject to Trust Indenture Act Section 311(a)
to the extent indicated.

designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency
in each Place of Payment for Securities of any series for such purposes. The
Company shall give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency. The Company hereby initially designates the Corporate Trust Office as
such office of the Company.
     Section 10.03 Money for Securities Payments to Be Held in Trust. If the
Company shall at any time act as its own Paying Agent with respect to any series
of Securities, it will, on or before each due date of the principal of or any
premium 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 any premium and 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 in writing 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 or any premium
or interest on any Securities of that series, deposit with a Paying Agent a sum
sufficient to pay such amount, such sum to be held as provided by the Trust
Indenture Act, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee in writing of its action or failure so to act.
     The Company will cause each Paying Agent for any series of Securities other
than the Trustee to execute and deliver to the Trustee an instrument in which
such Paying Agent shall agree with the Trustee, subject to the provisions of
this Section, that such Paying Agent will:
          (1) Hold all sums held by it for the payment of the principal of,
premium, if any, or interest on Securities of such series for the benefit of the
Persons entitled thereto until such sum shall be paid to such Persons or
otherwise disposed of as herein provided;

50

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

 

          (2) Give the Trustee written notice of any default by the Company (or
any other obligor upon the Securities of that series) and the making of any
payment of principal, premium, if any, or interest; and
          (3) Any time during the continuance of such default, upon the written
request of the Trustee, forthwith pay to the Trustee all sums so held 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 or any premium or
interest on any Security of any series and remaining unclaimed for two years
after such principal, premium or interest has become due and payable shall be
paid to the Company on Company Request, or (if then held by the Company) shall
be discharged from such trust; and the Holder of such Security shall thereafter,
as an unsecured general creditor, look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in New York City,
notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication,
any unclaimed balance of such money then remaining will be repaid to the
Company.
     Section 10.04 Corporate Existence. Subject to Article VIII, the Company
shall do or cause to be done all things necessary to preserve and keep in full
force and effect its corporate existence in accordance with its organizational
documents and its rights (charter and statutory) and corporate franchises;
provided, however , that the Company shall not be required to preserve any right
or franchise, if (a) the Board of Directors of the Company shall determine that
the preservation thereof is no longer desirable in the conduct of the business
of the Company and (b) the loss thereof is not disadvantageous in any material
respect to the Holders.
     Section 10.05 Compliance Certificate; Notice of Default.
          (1) The Company shall deliver to the Trustee annually an officer’s
certificate complying with Section 314(a)(4) of the Trust Indenture Act and
stating that, as to each such officer signing such certificate, whether or not
the signer knows of any failure by the Company or any Subsidiary of the Company
to comply with any conditions or covenants in this Indenture and, if such signer
does know of such a failure to comply, the certificate shall describe such
failure with particularity. The officer’s certificate shall also notify the
Trustee should the relevant fiscal year end on any date other than the current
fiscal year end date.

51

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

 

          (2) The Company shall, so long as any of the Securities of any series
are outstanding, deliver to the Trustee, within 30 days after becoming aware of
any Event of Default with respect to such series under this Indenture, an
Officer’s Certificate specifying such Event of Default and what action the
Company is taking or propose to take with respect thereto. The Trustee shall not
be deemed to have knowledge of an Event of Default unless one of its Responsible
Officers receives notice of the Event of Default from the Company or any of the
Holders.
ARTICLE XI
REDEMPTION OF SECURITIES
     Section 11.01 Applicability of Article. Securities of any series which are

their terms and (except as otherwise specified as contemplated by Section 3.01
for Securities of any series) in accordance with this Article.
     Section 11.02 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 of less than all the
Securities of any series, the Company shall, at least 45 days prior to the
Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee in writing of such Redemption
Date, of the principal amount of Securities of such series 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 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 Officer’s Certificate
evidencing compliance with such restriction.
     Section 11.03 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. 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.

52

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

 

     The Trustee shall promptly notify the Company in writing of the Securities
selected for redemption and, in the case of any Securities selected for partial
redemption, the principal amount thereof to be redeemed.
     For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be redeemed only in part, to the portion
of the principal amount of such Securities which has been or is to be redeemed.
     Section 11.04 Notice of Redemption. Notice of redemption shall be delivered
electronically or 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

be redeemed, the identification (and, in the case of partial redemption of any
Securities, the principal amount) of the particular Securities to be redeemed,
          (4) that on the Redemption Date the Redemption Price will become due
and payable upon each such Security to be redeemed and, if applicable, that
interest thereon will cease to accrue on and after said date,
          (5) in the case of any Securities that are convertible pursuant to
Article XIV, the conversion price or rate, 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,
          (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,
and
          (8) applicable CUSIP Numbers.
     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 (such notice to be prepared by the Company) in the name and at the
expense of the Company and shall be irrevocable. Notice of redemption of
Securities to be redeemed at the election of the Company received by the Trustee
shall be given by the Trustee to each Paying Agent in the name of and at the
expense of the Company.

53

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

 

     Section 11.05 Deposit of Redemption Price. On or prior to 10:00 a.m. New
York City time on the Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 10.03) 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 3.07) be paid to the Company upon Company Request or,
if then held by the Company, shall be discharged from such trust.
     Section 11.06 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 3.01, installments of interest whose Stated Maturity is on or prior to
the Redemption Date shall be payable to the Holders of such Securities, or one
or more Predecessor Securities, registered as such at the close of business on
the relevant Record Dates according to their terms and the provisions of
Section 3.07.
     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal and any premium shall, until paid, bear
interest from the Redemption Date at the rate prescribed therefor in the
Security.

series except as otherwise specified as contemplated by Section 3.01 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

     Section 12.02 Satisfaction of Sinking Fund Payments with Securities. The
Company (1) may deliver Outstanding Securities of a series (other than any
Securities previously called for redemption) and (2) may apply as a credit
Securities of a series which have been converted pursuant to Article XIV or
which have been redeemed either at the election of the Company pursuant to the
terms of such Securities or through the application of permitted optional
sinking fund payments pursuant to the terms of such Securities, in each case in
satisfaction of all or any part of any sinking fund payment with respect to the
Securities of such series required to be made pursuant to the terms of such
Securities as provided for by the terms of such series; provided that such
Securities have not been previously so credited. Such Securities shall be
received and credited for such purpose by the Trustee at the Redemption Price
specified in such Securities for redemption through operation of the sinking
fund and the amount of such sinking fund payment shall be reduced accordingly.
     Section 12.03 Redemption of Securities for Sinking Fund. Not less than
45 days prior to each sinking fund payment date for any series of Securities,

payment of cash and the portion thereof, if any, which is to be satisfied by
delivering and crediting Securities of that series pursuant to Section 12.02,
and will also deliver to the Trustee any Securities to be so delivered. Not less
than 30 days before each such sinking fund payment date the Trustee shall select
the Securities to be redeemed upon such sinking fund payment date in the manner
specified in Section 11.03 and cause notice of the redemption thereof to be
given in the name of and at the expense of the Company in the manner provided in
Section 11.04. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in
Section 11.06.
ARTICLE XIII

     Section 13.01 Company’s Option to Effect Defeasance or Covenant Defeasance.
The Company may elect, at its option by Board Resolution at any time, to have
either Section 13.02 or Section 13.03 applied to the Outstanding Securities of
any series designated pursuant to Section 3.01 as being defeasible pursuant to
this Article XIII (hereinafter called a “Defeasible Series”), upon compliance
with the conditions set forth below in this Article XIII; provided that Section
13.02 shall not apply to any series of Securities that is convertible into
Common Stock as provided in Article XIV or convertible into or exchangeable for
any other securities pursuant to Section 3.01(20).
     Section 13.02 Defeasance and Discharge. Upon the Company’s exercise of the
option provided in Section 13.01 to have this Section 13.02 applied to the
Outstanding Securities of any Defeasible Series, the Company shall be deemed to
have been discharged from its obligations, 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 13.04 are satisfied (hereinafter called
“Defeasance”), and the Trustee shall deliver to the Company appropriate
instruments of satisfaction, discharge and release (such instruments to be in
form and substance reasonably satisfactory to the Trustee). For this purpose,
such Defeasance means that the Company shall be deemed to have paid and

55

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

 

discharged the entire indebtedness represented by the Outstanding Securities of
such series and to have satisfied all its other obligations under the Securities
of such series and this Indenture (and the Trustee, at the expense of the
Company, shall execute proper instruments (such instruments to be in form and
substance reasonably satisfactory to the Trustee) acknowledging the same),
subject to the following which shall survive until otherwise terminated or
discharged hereunder: (1) the rights of Holders of Securities of such series to
receive, solely from the trust fund described in Section 13.04 and as more fully
set forth in such Section, payments in respect of the principal of and any
premium and interest on such Securities of such series when payments are due,

Article XIII. Subject to compliance with this Article XIII, the Company may
exercise its option provided in Section 13.01 to have this Section 13.02 applied
to the Outstanding Securities of any Defeasible Series notwithstanding the prior
exercise of its option provided in Section 13.01 to have Section 13.03 applied
to the Outstanding Securities of such series.
     Section 13.03 Covenant Defeasance. Upon the Company’s exercise of the
option provided in Section 13.01 to have this Section 13.03 applied to the
Outstanding Securities of any Defeasible Series, (1) the Company shall be
released from its obligations under Section 7.04 and Section 8.01 and
Section 10.04, and (2) the occurrence of any event specified in
Sections 5.01(3), 5.01(4) (with respect to any of Sections 8.01 and 10.04) and
5.01(5) shall be deemed not to be or result in an Event of Default (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 specified Section (to
the extent so specified in the case of Section 5.01(4)), whether directly or
indirectly by reason of any reference elsewhere herein to any such Section or by
reason of any reference in any such Section to any other provision herein or in
any other document, but the remainder of this Indenture and the Securities of
such series shall be unaffected thereby.
     Section 13.04 Conditions to Defeasance or Covenant Defeasance. The
following shall be the conditions to application of either Section 13.02 or
Section 13.03 to the Outstanding Securities of any Defeasible Series:

Article XIII 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 that through the
scheduled payment of principal and interest in respect thereof in accordance
with their terms will provide, not later than one day before the due date of any
payment, money in an amount, or (C) a combination thereof, in each case
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 any
such other qualifying trustee) to pay and discharge, the principal of and any
premium and interest on the Securities of such series on the respective Stated
Maturities, in accordance with the terms of this Indenture and the Securities of
such series. As used herein, “U.S. Government Obligation” means (x) any security

direct obligation of the United States of America for the payment of which full
faith and credit of the United States of America is pledged or (ii) an

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 (i) or (ii), is not callable or
redeemable at the option of the issuer thereof, and (y) any depositary receipt
issued by a bank (as defined in Section 3(a)(2) of the Securities Act) as

to the holder of such depositary receipt from any amount received by the
custodian in respect of the U.S. Government Obligation or the specific payment
of principal or interest evidenced by such depositary receipt.
          (2) In the case of an election under Section 13.02, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (A) the Company
has received from, or there has been published by, the Internal Revenue Service
a ruling or (B) since the date first set forth hereinabove, there has been a
change in the applicable Federal income tax law, in either case (A) or (B) to
the effect that, and based thereon such opinion shall confirm 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 the deposit, Defeasance and discharge
to be effected with respect to the Securities of such series and will be subject
to Federal income tax on the same amount, in the same manner and at the same
times as would be the case if such deposit, Defeasance and discharge were not to
occur.
          (3) In the case of an election under Section 13.03, 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 the deposit and Covenant
Defeasance to be effected with respect to the Securities of such series and will
be subject to Federal income tax on the same amount, in the same manner and at
the same times as would be the case if such deposit and Covenant Defeasance were
not to occur.
          (4) After giving pro forma effect to such Defeasance or Covenant
Defeasance, no Event of Default or event that (after notice or lapse of time or
both) would become an Event of Default shall have occurred and be continuing at
the time of such deposit or, with regard to any Event of Default or any such
event specified in Sections 5.01(6) and (7), at any time on or prior to the 90th
day after the date of such deposit (it being understood that this condition
shall not be deemed satisfied until after such 90th day).
          (5) Such Defeasance or Covenant Defeasance shall not cause the Trustee
to have a conflicting interest within the meaning of the Trust Indenture Act,
assuming all Securities of a series were in default within the meaning of the
Trust Indenture Act.
          (6) 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.

57

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

 

          (7) The Company shall have delivered to the Trustee an Opinion of
Counsel to the effect that any trust resulting from the deposit does not require
registration under the U.S. Investment Company Act of 1940, as amended.
          (8) No event or condition shall exist that, pursuant to the provisions
of Article XIII, would prevent the Company from making payments of the principal
of (and any premium) or interest on the Securities of such series on the date of
such deposit or at any time on or prior to the 90th day after the date of such
deposit (it being understood that this condition shall not be deemed satisfied
until such 90th day shall have ended).
          (9) The Company shall have delivered to the Trustee an Officer’s
Certificate and an Opinion of Counsel, each stating that all conditions
precedent with respect to such Defeasance or Covenant Defeasance have been
complied with.
     Section 13.05 Deposited Money and U.S. Government Obligations to be Held in
Trust; Other Miscellaneous Provisions.
     All money and U.S. Government Obligations (including the proceeds thereof)
deposited with the Trustee or other qualifying trustee (solely for purposes of
this Section and Section 13.06, the Trustee and any such other trustee are
referred to collectively as the “Trustee”) pursuant to Section 13.04 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 the Securities of such series
and this Indenture, to the payment, either directly or through any such Paying
Agent (including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of Securities of such series, of all sums due and to
become due thereon in respect of principal and any premium and interest, but
money so held in trust need not be segregated from other funds except to the
extent required by law.
     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 13.04 or the principal and interest received in
respect thereof other than any such tax, fee or other charge that by law is for
the account of the Holders of Outstanding Securities.
     Anything in this Article XIII to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or U.S. Government Obligations held by it as provided in Section 13.04
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 thereof that would then be required to be deposited to effect an
equivalent Defeasance or Covenant Defeasance with respect to the Securities of
such series.
     Section 13.06 Reinstatement. If the Trustee or the Paying Agent is unable
to apply any money in accordance with this Article XIII with respect to the
Securities of any series by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company’s obligations under this Indenture and the
Securities of such series shall be revived and reinstated as though no deposit
had occurred pursuant to this Article XIII with respect to Securities of such
series until such time as the

58

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

 

Trustee or Paying Agent is permitted to apply all money held in trust pursuant
to Section 13.05 with respect to Securities of such series in accordance with
this Article XIII; provided, however, that if the Company makes any payment of
principal of or any premium or interest on any Security of such series following
the reinstatement of its obligations, the Company, as the case may be, shall be
subrogated to the rights of the Holders of Securities of such series to receive
such payment from the money so held in trust.
ARTICLE XIV
CONVERSION OF SECURITIES
     Section 14.01 Applicability; 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 3.01 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 outstanding
principal amount thereof which is $1,000 or an integral multiple of $1,000 may,
at the times specified for conversion as hereinafter provided, 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 1/10,000
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 for Securities
of such series. In case a Security or portion thereof is called for redemption
at the election of the Company, such conversion right in respect of the Security
or portion so called shall expire at the close of business on the 10th calendar
day before 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 3.01, as it shall
be adjusted in certain instances as provided in this Article. The time or times
at which Securities of a series shall be convertible shall be as specified for
such series pursuant to Section 3.01.
     Section 14.02 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 of the Company maintained for that purpose pursuant to
Section 10.02, accompanied by written notice to the Company (which shall be
substantially in the form set forth in Section 2.03) 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 close of business on such Interest Payment Date shall (except in the
case of Securities or portions thereof which have been called for redemption on
a Redemption Date within such period) be accompanied by payment in 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

59

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

 

Section 3.07 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 final paragraph of Section 3.07, 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 14.03.
     Section 14.03 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 in respect
of such fraction in an amount equal to the same fraction of the daily closing
price per share of Common Stock (consistent with Section 14.04(6) below) at the
close of business on the day of conversion.
     Section 14.04 Adjustment of Conversion Price.
          (1) In case the Company shall pay or make a dividend or other
distribution on any class of capital stock of the Company in Common Stock, the
conversion price in effect at the opening of business on the day following the
date fixed for determination of shareholders 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. If, after any such date
fixed for determination, any dividend or distribution is not in fact paid, the
conversion price shall be immediately readjusted, effective as of the date the
Board of Directors

60

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

 

determines not to pay such dividend or distribution, to the conversion price
that would have been in effect if such determination date had not been fixed.
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 will not pay
any dividend or make any distribution on shares of Common Stock held in the
treasury of the Company.
          (2) In case the Company shall issue rights, options or warrants to all
holders of its Common Stock entitling them 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 shareholders entitled to
receive such rights, options or warrants (other than pursuant to a dividend
reinvestment plan), 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 that
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. If, after
any such date fixed for such determination, any such rights, options or warrants
are not in fact issued, or are not exercised prior to the expiration thereof,
the conversion price shall be immediately readjusted, effective as of the date
such rights, options or warrants expire, or the date the Board of Directors
determines not to issue any such rights, options or warrants, to the conversion
price that would have been in effect if the unexercised rights, options or
warrants had never been granted or such determination date had not been fixed,
as the case may be. 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
will not issue any rights, options or warrants in respect of shares of Common
Stock held in the treasury of the Company.
          (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 or rights, options or warrants to subscribe for or
purchase shares of any class of capital stock

61

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

 

(other than any rights, options or warrants that by their terms will also be
issued to any Holder upon conversion of a Security of such series into shares of
Common Stock without any action required by the Company or any other Person) or
other property (including cash or assets or securities, but excluding (i) any
rights, options or warrants referred to in paragraph (2) of this Section,
(ii) any dividend or distribution paid exclusively in cash, (iii) any dividend
or distribution referred to in paragraph (1) of this Section and (iv) any
consideration distributed in any merger or consolidation to which Section 14.11
applies, 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 shareholders
entitled to receive such distribution by a fraction of which the numerator shall
be the current market price per share (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 delivered to the Trustee) of the portion of the assets, shares or
evidences of indebtedness so distributed applicable to one share of Common Stock
and the denominator shall 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
shareholders entitled to receive such distribution. If, after any such date
fixed for determination, any such distribution is not in fact made, the
conversion price shall be immediately readjusted effective as of the date that
the Board of Directors determines not to make such distribution, to the
conversion price that would have been in effect if such determination date had
not been fixed. In the event the then fair market value (as so determined) of
the portion of the evidences of indebtedness, shares of any class of capital
stock or other property so distributed is equal to or greater than the current
market price per share of the Common Stock on such date, in lieu of the
foregoing adjustment, adequate provision shall be made so that each Holder of a
Security shall have the right to receive upon conversion the amount of such
evidences of indebtedness, shares of any class of capital stock or other
property such Holder would have received had such Holder converted each Security
on such date.
          (5) The reclassification of Common Stock into securities other than
Common Stock (other than any reclassification upon a consolidation or merger to
which Section 14.11 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 shareholders 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, and “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

62

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

 

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 (or, in case no such reported sale takes place on such day, the average of
the reported closing bid and asked prices) on such date as reported in composite
transactions for the principal national securities on which the Common Stock is
then listed or admitted to trading or, if the Common Stock is not listed or
admitted to trading on any national securities exchange, 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 or in the absence of any such quotations, as
determined by the Board of Directors in good faith.
          (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 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 pursuant to this section and its actions in so doing shall be
final and conclusive.
          (8) The Company may make such decreases to the conversion price, for
the remaining term of the securities of a series that is convertible or any
shorter term, in addition to those required by paragraphs (1), (2), (3), and
(4) of this section as it considers to be advisable 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.
          (9) No adjustment in the conversion price shall be required unless
such adjustment would require an increase or decrease of at least one percent in
such conversion price; provided, however, that any adjustment which by reason of
this paragraph (9) is 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 1/10,000 of a share, as the
case may be.
          (10) To the extent permitted by applicable law, the Company from time
to time may decrease the conversion price by any amount for any period of time
of at least twenty (20) days, the decrease being irrevocable during such period,
provided the Board of Directors shall have made a determination that such
decrease would be in the best interests of the Company, which determination
shall be conclusive. Whenever the conversion price is decreased pursuant to the
preceding sentence, the Company shall prepare a certificate signed by the
Treasurer or other appropriate officer of the Company stating the decreased
conversion price and the period during which it will be in effect, and such
certificate shall be delivered to the Trustee and the Conversion Agent at such
office or agency maintained for the purpose of conversion of securities pursuant
to Section 10.02 at least fifteen (15) days prior to the date the decreased
conversion price takes effect.

63

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

 

          (11) There shall be no adjustment to the conversion price upon the
issuance of rights under a rights agreement hereafter adopted prior to such
rights being separated from the Common Stock. If Holders of the Securities of a
series that is convertible exercise the right of conversion prior to the rights
trading separately from the Common Stock, such Holders shall receive rights in
addition to the Common Stock upon conversion of such Securities. If Holders of
the Securities of a series that is convertible exercise the right of conversion
after the date the rights issued under the Company’s rights agreement separate
from the underlying Common Stock, such Holders shall be entitled to receive the
rights that would otherwise be attributable to the shares of Common Stock
received upon conversion and the conversion rate, in such case, will be adjusted
as though such rights were being distributed to holders of Common Stock on the
date of such separation. If such an adjustment is made and such rights are later
redeemed, invalidated or terminated, then a corresponding reversing adjustment
will be made to the Conversion Rate on an equitable basis.
     Section 14.05 Notice of Adjustments of Conversion Price.
     Whenever the conversion price is adjusted as herein provided:
          (1) the Company shall compute the adjusted conversion price in
accordance with Section 14.04 and shall prepare a certificate signed by the
Treasurer or other appropriate officer 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 promptly be delivered to the
Trustee and the Conversion Agent at each office or agency maintained for the
purpose of conversion of Securities pursuant to Section 10.02; and
          (2) a notice stating that the conversion price has been adjusted and
setting forth the adjusted conversion price shall be required, and as soon as
practicable after it is required, such notice shall be delivered electronically
or mailed by the Company to all Holders at their last addresses as they shall
appear in the Security Register.
     Section 14.06 Notice of Certain Corporate Action.
     In case:
          (1) the Company shall declare a dividend (or any other distribution)
on its Common Stock payable otherwise than in cash; or
          (2) the Company shall authorize the granting to all 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 (other than pursuant to a
rights agreement referenced in Section 14.04(11)); or
          (3) 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 shareholders of the Company is required, or of the
sale or transfer of all or substantially all of the assets of the Company; or

64

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

 

          (4) 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 Section 10.02, 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 (1) or (2) above) prior to the applicable record or effective date
hereinafter specified, a notice stating (x) the date on which a record is to be
taken for the purpose of such dividend, distribution, rights or warrants, 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 or warrants are to
be determined, or (y) the date on which such reclassification, consolidation,
merger, share exchange, 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, share exchange, 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 (1) through (4) of this Section 14.06. If at the time the
Trustee shall not be the Conversion Agent, a copy of such notice shall also
forthwith be delivered by the Company to the Trustee.
     Section 14.07 Company to Reserve Common Stock. The Company shall at all
times reserve and keep available 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 14.08 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 the amount of any such tax, or has
established to the satisfaction of the Company that such tax has been paid.
     Section 14.09 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 14.08, the Company will pay all taxes, liens and charges with respect to
the issue thereof.
     Section 14.10 Cancellation of Converted Securities. All Securities
delivered for conversion shall be delivered to the Trustee to be cancelled by or
at the direction of the Trustee, which shall dispose of the same as provided in
Section 3.09.
     Section 14.11 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

65

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

 

the Company) or any sale or transfer of all or substantially all of the assets
of the Company, 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 convertible Security then outstanding shall have the right thereafter,
during the period such Security shall be convertible as specified in
Section 14.01, to convert such Security only into the kind and amount of
securities, cash and other property receivable upon such consolidation, merger,
sale or transfer 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 or transfer, assuming such holder of Common
Stock of the Company (i) is not (A) a Person with which the Company consolidated
or merged with or into or which merged into or with the Company or to which such
conveyance, sale, transfer or lease was made, as the case may be (a “Constituent
Person”), or (B) an Affiliate of a Constituent Person and (ii) failed to
exercise his, her or its rights of election, if any, as to the kind or amount of
securities, cash and other property receivable upon such consolidation, merger,
sale or transfer (provided that if the kind or amount of securities, cash and
other property receivable upon such consolidation, merger, sale or transfer is
not the same for each share of Common Stock of the Company 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 or transfer 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 or transfers.
     Section 14.12 Responsibility of Trustee. 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 Security, or for monitoring the price of
the Common Stock or effecting any calculations hereunder; 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 XIV.
     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.
