if made in the manner provided in this Section 1.4.

such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such

not later than ten days after setting a record date, the Company shall notify the Trustee and the Holders of such record date. If not set by the Company prior to the first solicitation of a Holder made by any Person in respect of any such action,
or, in the case of any such vote, prior to such vote, the record date for any such action or vote shall be the thirtieth day (or, if later, the date of the most recent list of Holders required to be provided pursuant to Section 13.1) prior to such
first solicitation or vote, as the case may be. With regard to any record date, the Holders on such date (or their duly appointed agents or proxies), and only such Persons, shall be entitled to give or take, or vote on, the relevant action, whether
or not such Holders remain Holders after such record date. Notwithstanding the foregoing, the Company shall not set a record date for, and the provisions of this paragraph shall not apply with respect to, any notice, declaration or direction

has occurred and is continuing and the Trustee shall not have given such a declaration to the Company, or (3) any direction referred to in Section 4.12, if the Trustee shall not have taken the action specified in such direction, then, with respect
to clauses (2) and (3), a record date shall automatically and without any action by the Company or the Trustee be 

 
 18 

 set for determining the Holders entitled to join in such declaration or direction, which record date shall be the close of business on the tenth
day (or, if such day is not a Business Day, the next succeeding Business Day) following the day on which the Trustee receives such declaration or direction, and, with respect to clause (1), the Trustee may set any day as a record date for the
purpose of determining the Holders entitled to join in such notice of default. Promptly after such receipt by the Trustee of any such declaration or direction referred to in clause (2) or (3), and promptly after setting any record date with respect
to clause (1), and as soon as practicable thereafter, the Trustee shall notify the Company and the Holders of any such record date so fixed. The Holders on such record date (or their duly appointed agents or proxies), and only such Persons, shall be
entitled to join in such notice, declaration or direction, whether or not such Holders remain Holders after such record date; provided, however, that, unless such notice, declaration or direction shall have become effective by virtue of Holders of
the requisite principal amount of Securities on such record date (or their duly appointed agents or proxies) having joined therein on or prior to the ninetieth day after such record date, such notice, declaration or direction shall automatically and
without any action by any Person be cancelled and of no further effect. Nothing in this paragraph shall be construed to prevent a Holder (or a duly appointed agent or proxy thereof) from giving, before or after the expiration of such 90-day period,
a notice, declaration or direction contrary to or different from, or, after the expiration of such period, identical to, the notice, declaration or direction to which such record date relates, in which event a new record date in respect thereof
shall be set pursuant to this paragraph. In addition, nothing in this paragraph shall be construed to render ineffective any notice, declaration or direction of the type referred to in this paragraph given at any time to the Trustee and the Company
by Holders (or their duly appointed agents or proxies) of the requisite principal amount of Securities on the date such notice, declaration or direction is so given. 
  
 (f) Except as provided in Sections 4.2 and 4.13, any request, demand, authorization, direction, notice, consent, election, waiver or other Act of the Holder of any Security
shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the
Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security.

to each Holder of a Security affected by such event, at the address of such Holder as it appears in the Security Register, not earlier than the earliest date and not later than the latest date prescribed for the giving of such notice. 

 
 Neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Registered
Security shall affect the sufficiency of such notice with respect to other Holders of Registered Securities. In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by
mail, then such notification to Holders of Registered Securities as shall be made with the approval of the Trustee, which approval shall not be unreasonably withheld or delayed, shall constitute a sufficient notification to such Holders for every
purpose hereunder. 
  
 Such notice shall be deemed to have been given when such notice is mailed. 

 
 Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive
such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders of Securities 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.

the construction hereof.

 Except as provided in the next sentence, nothing in this Indenture or in the Securities, express or implied, shall give to any Person,
other than the parties hereto and their successors and assigns hereunder and the Holders of Securities, any benefit or legal or equitable right, remedy or claim under this Indenture. The provisions of Article Eleven are intended to be for the
benefit of, and shall be enforceable directly by, the holders of Senior Debt. 
  
 SECTION 1.11 Governing Law.

  
 THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
NEW YORK, THE UNITED STATES OF AMERICA, INCLUDING, WITHOUT LIMITATION, THE NEW YORK GENERAL OBLIGATIONS LAW ss.5-1401. 
  
 SECTION 1.12 Legal Holidays. 
  
 In any case where any Interest Payment Date, Redemption Date,
Repurchase Date or Stated Maturity of any Security or the last day on which a Holder of a Security has a right to convert his Security shall not be a Business Day at a Place of Payment or Place of Conversion, as the case may be, then
(notwithstanding any other provision of this Indenture or of the Securities) payment of principal of, premium, if any, or interest on, or the payment of the Repurchase Price (whether the same is payable in cash or in shares of Common Stock) with
respect to, or delivery for conversion of, such Security need not be made at such Place of Payment or Place of Conversion, as the case may be, on or by such day, but may be made on or by the next succeeding Business Day at such Place of Payment or
Place of Conversion, as the case may be, with the same force and effect as if made on the Interest Payment Date, Redemption Date or Repurchase Date, or at the Stated Maturity or by such last day for conversion; provided, however, that in the case
that payment is made on such succeeding Business Day, no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date, Redemption Date, Repurchase Date, Stated Maturity or last day for conversion, as the
case may be. 
  
 SECTION 1.13 Conflict with Trust Indenture Act. 
  
 If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under such act to be a
part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified or to be excluded, as the case may be. Until such time as this Indenture 

 
 21 

 shall be qualified under the Trust Indenture Act, this Indenture, the Company and the Trustee shall be deemed for all purposes hereof to be
subject to and governed by the Trust Indenture Act to the same extent as would be the case if this Indenture were so qualified on the date hereof. 
  
 SECTION 1.14 Counterparts. 
  
 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.

 THE SECURITIES 
  
 SECTION 2.1 Form Generally. 
  
 The Securities and the Trustee’s Certificate of Authentication shall be in substantially the form set forth in Exhibit A hereto,
which Exhibit is a part of this Indenture, with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by this Indenture, and may have such letters, numbers or other marks of identification and such
legends or endorsements placed thereon as may be required to comply with the rules of any securities exchange or the Internal Revenue Code of l986, as amended, and regulations thereunder (the “Code”), or as may, consistently herewith, be
determined by the officers executing such Securities, as evidenced by their execution thereof. All Securities shall be issued in registered form, as opposed to bearer form, and shall sometimes be referred to as the “Registered Securities.”

  
 The Securities shall be printed, lithographed, typewritten or engraved or produced by any combination of these
methods on steel engraved borders, if so required by any securities exchange upon which the Securities may be listed, or may be produced in any other manner permitted by the rules of any such securities exchange, or, if the Securities are not listed
on a securities exchange, in any other manner approved by the Company, all as determined by the officers executing such Securities, as evidenced by their execution thereof. 
  
 Upon their original issuance, Securities shall be issued in the form of one or more Global Securities without interest coupons and shall be registered in the name of DTC,
as Depositary, or its nominee and deposited with the Trustee, as custodian for DTC, for credit by DTC to the respective accounts of beneficial owners of the Securities represented thereby (or such other accounts as they may direct). Such Global
Security, together with its Successor Securities that are Global Securities, are collectively herein called the “Global Security.” 
  
 SECTION 2.2 Title and Terms. 
  
 The aggregate principal amount of
Securities that may be authenticated and delivered under this Indenture is limited to U.S.$102,800,000, except for Securities authenticated and delivered in exchange for, or in lieu of, other Securities pursuant to Section 2.5, 2.6, 2.7, 7.5, 9.8,
10.2 or 12.3(e). 

 
 22 

  
 The Securities shall be known and designated as the “5.75% Convertible
Senior Subordinated Notes due June 15, 2008” of the Company. Their Stated Maturity shall be June 15, 2008 and they shall bear interest on their principal amount from             ,
2002, payable semiannually in arrears on June 15 and December 15 in each year, commencing June 15, 2003, at the rate of 5.75% per annum until the principal thereof is due and at the rate then in effect on any overdue principal and, to the extent
permitted by law, on any overdue interest; provided, however, that payments shall only be made on Business Days as provided in Section 1.12. 
  
 The principal of, premium, if any, and interest on the Securities shall be payable as provided in the form of Securities attached hereto as Exhibit A, and the Repurchase Price, whether payable in cash
or in shares of Common Stock, shall be payable at such places as are identified in the Company Notice given pursuant to Section 12.3 (any city in which any Paying Agent is located being herein called a “Place of Payment”). 

 
 The Securities shall be redeemable at the option of the Company, as provided in Article Nine and in the form of Securities
attached hereto as Exhibit A. 
  
 The Securities shall be convertible as provided in Article Ten (any city in which
any Conversion Agent is located being herein called a “Place of Conversion”). 
  
 The Securities shall be
subordinated in right of payment to Senior Debt of the Company as provided in Article Eleven. 
  
 The Securities
shall be subject to repurchase by the Company at the option of the Holders as provided in Article Twelve. 
  
 SECTION
2.3 Denominations. 
  
 The Securities shall be issuable only in registered form, without coupons, in denominations of
U.S.$1,000 and integral multiples thereof. 
  
 SECTION 2.4 Execution, Authentication, Delivery and Dating.

  
 The Securities shall be executed on behalf of the Company by its Chairman of the Board, its Vice Chairman of the
Board, its Chief Executive Officer, its President, one of its Vice Presidents, its Chief Financial Officer, its Treasurer or its Controller and attested by its Secretary or one of its Assistant Secretaries. Any such signature may be manual or
facsimile. 
  
 Securities bearing the manual or facsimile signature of individuals who were at any time the proper
officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such
Securities. 
  
 At any time and from time to time after the execution and delivery of this Indenture, the Company may
deliver Securities executed by the Company to the Trustee or to its order for 

 
 23 

 authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with such
Company Order shall authenticate and make available for delivery such Securities as provided in this Indenture and not otherwise. 
  
 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 of an authorized
signatory, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. 
  
 SECTION 2.5 Global Securities; Temporary Securities. 
  
 (a) Global Securities. 
  
 (1) Each Global Security authenticated under this
Indenture shall be registered in the name of the Depositary designated by the Company 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, 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 (i) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or (ii) has ceased to be a clearing agency registered as such under the
Exchange Act or announces an intention permanently to cease business or does in fact do so or (B) there shall have occurred and be continuing an Event of Default with respect to such Global Security. 
  
 (3) If any Global Security is to be exchanged for other Securities or cancelled in whole, it shall be surrendered by or on
behalf of the Depositary or its nominee to the Trustee, as Security Registrar, for exchange or cancellation, as provided in this Article Two. If any Global Security is to be exchanged for other Securities or cancelled in part, or if another Security
is to be exchanged in whole or in part for a beneficial interest in any Global Security, in each case, as provided in Section 2.6, then either (A) such Global Security shall be so surrendered for exchange or cancellation, as provided in this Article
Two, or (B) the principal amount thereof shall be reduced or increased by an amount equal to the portion thereof to be so exchanged or cancelled or equal to the principal amount of such other Security to be so exchanged for a beneficial interest
therein, as the case may be, by means of an appropriate adjustment made on the records of the Trustee, as Security Registrar, whereupon the Trustee, in accordance with the Applicable Procedures, shall instruct the Depositary or its authorized
representative to make a corresponding adjustment to its records. Upon any such surrender or adjustment of a Global Security, the Trustee shall, subject to Section 2.6(c) and as otherwise provided in this Article Two, authenticate and make available
for delivery any Securities issuable in exchange for such Global Security (or any portion thereof) to or upon the order 

 
 24 

 of, and registered in such names as may be directed by, the Depositary or its authorized representative. Upon the request
of the Trustee in connection with the occurrence of any of the events specified in the preceding paragraph, the Company shall promptly make available to the Trustee a reasonable supply of Securities that are not in the form of Global Securities. The
Trustee shall be entitled to rely upon any order, direction or request of the Depositary or its authorized representative which is given or made pursuant to this Article Two. 
  
 (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 Article Two or otherwise, shall be authenticated and delivered in the form of, and shall be, a registered 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, in which case such Registered Security shall be authenticated and delivered in definitive, fully registered form, without interest coupons. 
  
 (5) The Depositary or its nominee, as registered owner of a Global Security, shall be the Holder of such Global Security for all purposes under the
Indenture and the Registered Securities, and owners of beneficial interests in a Global Security shall hold such interests pursuant to the Applicable Procedures. Accordingly, any such owner’s beneficial interest in a Global Security shall be
shown only on, and the transfer of such interest shall be effected only through, records maintained by the Depositary or its nominee or its Agent Members, and such owners of beneficial interests in a Global Security shall not be considered the
owners or holders thereof. 
  
 (b) Temporary Securities. 
  
 Pending the preparation of definitive Securities, the Company may execute, and upon Company Order the Trustee shall authenticate and make available for delivery, temporary
Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Registered Securities in lieu of which they are issued and with such
appropriate insertions, omissions, substitutions and other variations as the officers executing such Registered Securities may determine, as evidenced by their execution of such Securities. 
  
 If temporary Securities are issued, the Company shall cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities,
the temporary Securities shall be exchangeable for definitive Securities upon surrender of the temporary Securities at any office or agency of the Company designated pursuant to Section 8.2, without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Securities, the Company shall execute and the Trustee shall authenticate and make available for delivery in exchange therefor a like principal amount of definitive Securities of authorized denominations.

  
 Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities. 

 
 25 

  
 SECTION 2.6 Registration, Registration of Transfer and Exchange; Restrictions on
Transfer. 
  
 (a) The Company shall cause to be kept at the Corporate Trust Office a register (the register
maintained in such office and in any other office or agency of the Company designated pursuant to Section 8.2 being herein sometimes collectively referred to as the “Security Register”) in which, subject to such reasonable regulations as
it may prescribe, the Company shall provide for the registration of Registered Securities and of transfers of Registered Securities. The Trustee is hereby appointed “Security Registrar” for the purpose of registering Registered Securities
and transfers and exchanges of Registered Securities as herein provided. 
  
 Upon surrender for registration of
transfer of any Security at an office or agency of the Company designated pursuant to Section 8.2 for such purpose, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees,
one or more new Securities of any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by this Indenture. 
  
 At the option of the Holder, and subject to the other provisions of this Section 2.6, Securities may be exchanged for other Securities of any authorized denomination and of
a like aggregate principal amount, upon surrender of the Securities to be exchanged at any such office or agency. Whenever any Securities are so surrendered for exchange, and subject to the other provisions of this Section 2.6, the Company shall
execute, and the Trustee shall authenticate and make available for delivery, the Securities the Holder making the exchange is entitled to receive. Every Security presented or surrendered for registration of transfer or for exchange shall (if so
required by the Company or the Security Registrar) 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. 
  
 All Securities issued upon any registration of transfer or exchange of Securities shall be
the valid obligations of the Company, evidencing the same debt, subject to the other provisions of this Section 2.6, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or
exchange. 
  
 No service charge shall be made for any registration of transfer or exchange of Securities except as
provided in Section 2.7, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges
pursuant to Section 2.5, 7.5, 9.8, 10.2 or 12.3(e) (other than where the shares of Common Stock are to be issued or delivered in a name other than that of the Holder of the Security) not involving any transfer and other than any stamp and other
duties, if any, that may be imposed in connection with any such transfer or exchange by the United States or any political subdivision thereof or therein, which shall be paid by the Company. 
  
 In the event of a redemption of the Securities, the Company shall not be required (1) to register the transfer of or exchange Securities for a period of 15 days immediately
preceding the date 

 
 26 

 notice is given identifying the serial numbers of the Securities called for such redemption or (2) to register the transfer of or exchange any
Security, or portion thereof, called for redemption. 
  
 (b) Neither the Trustee, the Paying Agent nor any of their
agents shall (1) have any duty to monitor compliance with or with respect to any federal or state or other securities or tax laws or (2) have any duty to obtain documentation on any transfers or exchanges other than as specifically required
hereunder. 
  
 SECTION 2.7 Mutilated, Destroyed, Lost or Stolen Securities. 
  
 If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and make available
for delivery in exchange therefor a new Security of like tenor and principal amount and bearing a number not contemporaneously outstanding. 
  
 If there be delivered to the Company and to the Trustee: 
  
 (a) evidence to their satisfaction of the destruction, loss or theft of any Security, and 
  
 (b) such security or indemnity as may be satisfactory to the Company and the Trustee to save each of them and any agent of either of them harmless, then, in the absence of actual 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 make available for delivery, in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal
amount and bearing a number not contemporaneously outstanding. 
  
 In case any such mutilated, destroyed, lost or
stolen Security has become or is about to become due and payable, the Company in its discretion, but subject to any conversion rights, may, instead of issuing a new Security, pay such Security, upon satisfaction of the conditions set forth in the
preceding paragraph. 
  
 Upon the issuance of any new Security under this Section 2.7, 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 (other than any stamp and other duties, if any, that may be imposed in connection therewith by the United States or any political
subdivision thereof or therein, which shall be paid by the Company) and any other expenses (including the fees and expenses of the Trustee) connected therewith. 
  
 Every new Security issued pursuant to this Section 2.7 in lieu of any mutilated, 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 such new Security shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities
duly issued hereunder. 

 
 27 

 The provisions of this Section 2.7 are exclusive and shall preclude (to the extent lawful) all other rights and remedies
of any Holder with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 
  
 SECTION 2.8 Payment of Interest; Interest Rights Preserved. 
  
 Interest on any Security that is
payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for
such interest. 
  
 Any interest on any Security that is payable, but is not punctually paid or duly provided for, on
any Interest Payment Date (“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 (a) or (b) below: 
  
 (a) The Company may elect to make
payment of any Defaulted Interest to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be
fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security, the date of the proposed payment and the Special Record Date, 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 provided in this clause. The Special Record Date for the payment of such Defaulted Interest 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 15 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee, in the name and at the expense of the Company, shall cause notice of
the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder at such Holder’s 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 mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities (or their respective
Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (b). 
  
 (b) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on
which the Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by
the Trustee. 

 
 28 

 Subject to the foregoing provisions of this Section 2.8 and Section 2.6, 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, that were carried by such other Security. 
  
 Interest on any Security that is converted in accordance with Section 10.2 during a Record Date Period shall be payable in accordance with
the provisions of Section 10.2. 
  
 SECTION 2.9 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, premium, if any, and (subject to Section 2.8) 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 2.10 Cancellation. 
  
 All
Securities surrendered for payment, redemption, repurchase, registration of transfer or exchange or conversion shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee. All Securities so delivered to the Trustee shall
be cancelled promptly by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section 2.10. The Trustee shall dispose of all cancelled Securities in accordance with applicable
law and its customary practices in effect from time to time. 
  
 SECTION 2.11 Computation of Interest. 

 
 Interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months. 
  
 SECTION 2.12 CUSIP Numbers. 
  
 The Company in issuing Securities may use “CUSIP” numbers (if then generally in use) in addition to serial numbers; the Trustee shall use such CUSIP numbers in addition to serial numbers in notices of redemption
and repurchase as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such CUSIP numbers either as printed on the Securities or as contained in any notice of a
redemption or repurchase and that reliance may be placed only on the serial or other identification numbers printed on the Securities, and any such redemption or repurchase shall not be affected by any defect in or omission of such CUSIP numbers.
The Company shall promptly notify the Trustee in writing of any change in any such CUSIP number.

 If an Event of Default (other than an Event of Default specified in Section 4.1(f) or 4.1(g)) 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 may declare the principal of all the Securities to be due and payable immediately, by a notice in writing to the Company (and to the
Trustee if given by the Holders), and upon any such declaration, such principal and all accrued interest thereon shall become immediately due and payable. If an Event of Default specified in Section 4.1(f) or 4.1(g) occurs, the principal of, and
accrued interest on, all the Securities shall ipso facto become immediately due and payable without any declaration or other Act of the Holder or any act on the part of the Trustee. 
  
 At any time after such declaration of acceleration 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 Four provided, the Holders of a majority in principal amount of the Outstanding Securities, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if: 

 
 (a) the Company has paid or deposited with the Trustee a sum sufficient to pay (1) all overdue interest on all
Securities, (2) the principal of and premium, if any, on any Securities that have become due otherwise than by such declaration of acceleration and any interest thereon at the rate borne by the Securities, (3) to the extent permitted by applicable
law, interest upon overdue interest at the rate then in effect, and (4) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel; and

  
 (b) all Events of Default, other than the non-payment of the principal of, and any premium and
interest on, Securities that have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 4.13. 
  
 No rescission or annulment referred to above shall affect any subsequent default or impair any right consequent thereon. 
  
 SECTION 4.3 Collection of Indebtedness and Suits for Enforcement by Trustee. 
  
 The Company covenants that if: 
  
 (a) default is
made in the payment of any interest on any Security when it becomes due and payable and such default continues for a period of 30 days, or 
  
 (b) default is made in the payment of the principal of or premium, if any, on any Security at the Maturity thereof, the Company will upon demand of the Trustee pay to it, for the 

 
 33 

 benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal,
premium, if any, and interest on any overdue principal, premium, if any, and, to the extent permitted by applicable law, on any overdue interest at the rate then in effect, and in addition thereto, such further amount as shall be sufficient to cover
the reasonable costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel. 
  
 If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding
for the collection of the sums so due and unpaid, ma prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Securities and collect the moneys adjudged or decreed to be payable
in the manner provided by law out of the property of the Company or any other obligor upon the Securities, wherever situated. 
  
 If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities by such appropriate judicial proceedings as the Trustee shall
deem most effective 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 4.4 Trustee May File Proofs of Claim. 
  
 In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relating
to the Company or any other obligor upon th Securities or the property of the Company or of such other obligor or the creditors of either, the Trustee (whether or not the principal of, and any interest on, the Securities shall then be due and
payable as therein expressed or by declaration or otherwise and whether or not the Trustee shall have made any demand on the Company for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such
proceeding or otherwise, 
  
 (a) to file and prove a claim for the whole amount of principal,
premium, if any, and interest owing and unpaid in respect of the Securities and take such other actions, including participating as a member, voting or otherwise, of any official committee of creditors appointed in such matter, and to file such
other papers or documents, in each of the foregoing cases, as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents and its counsel) and of the Holders of Securities allowed in such judicial proceeding, and 
  
 (b) to collect and receive any moneys or other property payable or deliverable on any such claim 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 of Securities 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 of Securities, to pay to the
Trustee 

 
 34 

 any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
its counsel and any other amounts due the Trustee under Section 5.7. 
  
 Nothing herein contained shall be deemed to
authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Security 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 of a Security in any such proceeding; provided, however, that the Trustee may, on behalf of such Holders, vote for the election of a trustee in bankruptcy or similar official. 

 
 SECTION 4.5 Trustee May Enforce Claims without Possession of Securities. 
  

All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or
the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, be for the ratable benefit of the Holders of the Securities in respect of which judgment has been recovered. 
  
 SECTION 4.6 Application of Money Collected. 
  
 Subject to Article Eleven, any money collected by the Trustee pursuant to this Article Four 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, premium, if any, or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 
  
 FIRST: To the payment of all amounts due the Trustee under Section 5.7; 
  
 SECOND: To the payment of the amounts then due and unpaid for principal of, premium, if any, or 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, premium, if any, and interest,
respectively; and 
  
 THIRD: Any remaining amounts shall be repaid to the Company. 

 
 SECTION 4.7 Limitation on Suits. 
  
 No Holder of any Security shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment o a receiver or trustee, or for any other
remedy hereunder, unless: 
  
 (a) such Holder has previously given written notice to the Trustee of a
continuing Event of Default; 

 
 35 

 (b) the Holders of not less than 25% in principal amount of the Outstanding Securities 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; 
  
 (c) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request; 
  
 (d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any
such proceeding; and 
  
 (e) the Trustee has not received any direction inconsistent with such
written request from the Holders of a majority of the aggregate principal amount of the Outstanding Securities during the 60 day period referred to in (d) above; 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 seek to obtain priority or 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 such Holders. 
  
 SECTION 4.8 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, premium, if any, and
(subject to Section 2.8) interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption or repurchase, on the Redemption Date or Repurchase Date, as the case may be), and to convert such
Security in accordance with Article Ten, 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 4.9 Restoration of Rights and Remedies. 
  
 If the Trustee or any Holder of a Security 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 of Securities shall be restored severally and respectively to
their former positions hereunder and thereafter all rights and remedies of the Trustee and such Holders shall continue as though no such proceeding had been instituted. 
  
 SECTION 4.10 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 2.7, no right or remedy herein conferred upon or reserved to the Trustee or
to the Holders of Securities is intended to be exclusive 

 
 36 

 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 4.11 Delay or Omission Not Waiver. 
  
 No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event of Default
shall impair any such right or remedy or constitute a waiver of any such Event of Default or any acquiescence therein. Every right and remedy given by this Article Four or by law to the Trustee or to the Holders of Securities may be exercised from
time to time, and as often as may be deemed expedient, by the Trustee or (subject to the limitations contained in this Indenture) by the Holders of Securities, as the case may be. 
  
 SECTION 4.12 Control by Holders of Securities. 
  
 The Holders of a majority in principal amount of the Outstanding Securities shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or

 (a) such direction shall not be in conflict with
any rule of law or with this Indenture, and 
  
 (b) the Trustee may take any other action deemed
proper by the Trustee that is not inconsistent with such direction. 
  
 SECTION 4.13 Waiver of Past Defaults.

  
 The Holders, either (a) through the written consent of not less than a majority in principal amount of the
Outstanding Securities or (b) by the adoption of a resolution, at a meeting of Holders of the Outstanding Securities at which a quorum is present, by the Holders of at least a majority in principal amount of the Outstanding Securities represented at
such meeting, may on behalf of the Holders of all the Securities waive any past default hereunder and its consequences, except a default (1) in the payment of the principal of, premium, if any, interest, or the Repurchase Price on any Security or
(2) in respect of a covenant or provision hereof that under Article Seven cannot be modified or amended without the consent of the Holder of each Outstanding Security 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 4.14 Undertaking for Costs. 

 
 37 

 All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have
agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due
regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 4.14 shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted
by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Outstanding Securities, or to any suit instituted by any Holder of any Security for the enforcement of the payment of the principal of, premium, if
any, or interest on any Security on or after the respective Stated Maturity or Maturities expressed in such Security (or, in the case of redemption or repurchase, on or after the Redemption Date or Repurchase Date, as the case may be) or for the
enforcement of the right to convert any Security in accordance with Article Ten. 
  
 SECTION 4.15 Waiver of Stay,
Usury or Extension Laws. 
  
 The Company covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, usury or extension law wherever enacted, now or at any time hereafter in force, that 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 by reason of such law 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 FIVE 
  
 THE TRUSTEE 
  
 SECTION 5.1 Certain Duties and Responsibilities. 
  
 (a) Except during the continuance of an Event of Default, 
  
 (1) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 

 
 (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the
statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions that by any provision
hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the 

 
 38 

 same to determine whether or not they conform to the requirements of this Indenture but not to verify the contents
thereof. 
  
 (b) In case 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 man would exercise or use under the circumstances in the conduct of his own affairs. 
  
 (c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that 
  
 (1) this paragraph (c) shall
not be construed to limit the effect of paragraph (a) of this Section 5.1; 
  
 (2) the Trustee shall
not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; 
  
 (3) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the
Holders of a majority in principal amount of the Outstanding Securities relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under
this Indenture; and 
  
 (4) no provision of this Indenture shall require the Trustee to expend or
risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to it. 
  
 (d) Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 5.1. 
  
 SECTION 5.2 Notice of Defaults. 
  
 Within 90 days after the occurrence of any default hereunder as to which a Responsible Officer of the Trustee has actually received written notice, the Trustee shall give to all Holders of Securities,
in the manner provided in Section 1.6, notice of such default, unless such default shall have been cured or waived; provided, however, that, except in the case of a default in the payment of the principal of, premium, if any, or interest on any
Security, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors or Responsible Officers of the Trustee in good faith determine that the
withholding of such notice is in the interest of the Holders. For the purpose of this Section 5.2, the 

 
 39 

 term “default” means any event that is, or after notice or lapse of time or both would become, an Event of Default. 

 
 SECTION 5.3 Certain Rights of Trustee. 
  
 Subject to the provisions of Section 5.1:

note, coupon, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties; 
  
 (b) any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order and any resolution of the
Board of Directors shall be sufficiently evidenced by a Board Resolution; 
  
 (c) whenever in the
administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in
the absence of bad faith on its part, rely upon an Officers’ Certificate; 
  
 (d) the Trustee
may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in
reliance thereon; 
  
 (e) the Trustee shall be under no obligation to exercise any of the rights or
powers vested in it by this Indenture at the request or direction of any of the Holders of Securities pursuant to this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and
liabilities that might be incurred by it in compliance with such request or direction; 
  
 (f) the
Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon, other evidence
of indebtedness or other paper or document, but the Trustee may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be
entitled to examine the books, records and premises of the Company, personally or by agent or attorney; and 
  
 (g) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys, and the Trustee shall not be responsible for any misconduct or negligence on the

 SECTION 5.4 Not Responsible for Recitals or Issuance of Securities. 

 
 The recitals contained herein and in the Securities (except the Trustee’s certificates of authentication) shall be taken
as the statements of the Company, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture, of the Securities or of the Common Stock issuable upon the
conversion of the Securities. The Trustee shall not be accountable for the use or application by the Company of Securities or the proceeds thereof. 
  
 SECTION 5.5 May Hold Securities, Act as Trustee under Other Indentures. 
  
 The Trustee, any Authenticating Agent, any Paying Agent, any Conversion Agent or any other agent of the Company or the Trustee, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise
deal with the Company with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Conversion Agent or such other agent. 
  
 The Trustee may become and act as trustee under other indentures under which other securities, or certificates of interest or participation in other securities, of the Company are outstanding in the
same manner as if it were not Trustee hereunder. 
  
 SECTION 5.6 Money Held in Trust. 
  
 Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee
shall be under no liability for interest on any money received by it hereunder, except as otherwise agreed in writing with the Company. 
  
 SECTION 5.7 Compensation and Reimbursement. 
  
 The Company agrees 
  
 (a) to pay to the Trustee from time to time such reasonable compensation as the Company and the Trustee shall from time to
time agree in writing for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); 
  

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

  
 (c) to indemnify the Trustee (and its directors, officers, employees and agents) for, and to hold
it harmless against, any and all loss, damage, claim, liability or expense, including taxes (other than taxes based on the income of the Trustee), incurred without negligence, bad faith or 

 
 41 

 willful misconduct on its part, arising out of or in connection with the acceptance or administration of this trust,
including the reasonable costs, expenses and reasonable attorneys’ fees of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. 
  
 When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 4.1(f) or Section 4.1(g)
with respect to the Company, the expenses (including the reasonable charges of its counsel) and the compensation for the services are intended to constitute expenses of the administration under any applicable federal or state bankruptcy, insolvency
or other similar law. 
  
 The Trustee shall have a lien prior to the Securities as to all property and funds held by
it hereunder for any amount owing it or any predecessor Trustee pursuant to this Section 5.7, except with respect to funds held in trust for the benefit of the Holders of particular Securities. 
  

The provisions of this Section 5.7 shall survive the termination of this Indenture or the earlier resignation or removal of the Trustee. 
  
 SECTION 5.8 Corporate Trustee Required; Eligibility. 
  
 There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such, having a combined capital and

business or agency in the Borough of Manhattan, The City of New York. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of
this Section 5.8, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 5.8, it shall resign immediately in the manner and with the effect hereinafter specified in this Article and a successor shall be appointed pursuant to Section 5.9. 
  
 SECTION 5.9 Resignation and Removal; Appointment of Successor.

by the successor Trustee in accordance with the applicable requirements of Section 5.10. 
  
 (b) The Trustee may
resign at any time by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 5.10 shall not have been delivered to the Trustee within 30 days after the giving of such notice of
resignation, the resigning Trustee or the Company may petition any court of competent jurisdiction for the appointment of a successor Trustee. 

 
 42 

 (c) The Trustee may be removed at any time by Act of the Holders of a majority in principal amount of the Outstanding
Securities, delivered to the Trustee and the Company. If the instrument of acceptance by a successor Trustee required by Section 5.10 shall not have been delivered to the Trustee within 30 days after the giving of such notice of removal, the removed
Trustee or the Company may petition any court of competent jurisdiction for the appointment of a successor Trustee. 
  
 (d) If at any time: 
  
 (1) the Trustee shall cease to be eligible under Section 5.8
and shall fail to resign after written request therefor by the Company or by any Holder of a Security who has been a bona fide Holder of a Security for at least six months, or 
  
 (2) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be
appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 
  
 then, (i) in any such case the Company may remove the Trustee, or (ii) in the case of clause (d)(1) above only and subject to Section 4.14, any Holder of a Security who has been a bona fide Holder of a
Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
  
 (e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any
cause, the Company shall promptly appoint a successor Trustee and shall comply with the applicable requirements of this Section 5.9 and Section 5.10. If, within one year after such resignation, removal or incapability, or occurrence of suc vacancy,
a successor Trustee shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with the applicable requirements of Section 5.10, become the successor Trustee and supersede the successor Trustee appointed by the Company. If no successor Trustee shall have been so appointed by the Company or the
Holders of Securities and accepted appointment in the manner required by this Section 5.9 and Section 5.10, any Holder of a Security who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee. 
  
 (f)
The successor Trustee shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee to all Holders of Securities in the manner provided in Section 1.6. Each notice shall include the name of the
successor Trustee and the address of its Corporate Trust Office. 
  
 SECTION 5.10 Acceptance of Appointment by
Successor. 

 
 43 

  
 Every successor Trustee appointed hereunder shall execute, acknowledge and
deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee. Such retiring Trustee shall, upon payment of its charges, promptly execute and deliver an instrument transferring to such successor Trustee all
the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts. 
  
 No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be eligible under this Article. 
  
 SECTION 5.11 Merger, Conversion, Consolidation or Succession to Business. 
  
 Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder (provided such corporation shall be
otherwise eligible under this Article), without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office,
any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

  
 SECTION 5.12 Authenticating Agents. 
  
 The Trustee may, with the consent of the Company, appoint an Authenticating Agent or Agents acceptable to the Company with respect to the Securities, which shall be
authorized to act on behalf of the Trustee to authenticate Securities issued upon exchange or substitution pursuant to this Indenture. 
  
 Securities authenticated by an Authenticating Agent shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder, and every reference in
this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a
certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be subject to acceptance by the Company and shall at all times be a corporation organized and doing business under the laws
of the United States of America, any state thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent and subject to supervision or examination by government or other fiscal authority. If at any time an
Authenticating Agent shall 

 
 44 

 cease to be eligible in accordance with the provisions of this Section 5.12, such Authenticating Agent shall resign immediately in the manner
and with the effect specified in this Section 5.12. 
  
 Any corporation into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or

aggregate principal amount of Securities at the time Outstanding.

 SECTION 8.3 Money for Security Payments to Be Held in Trust. 

 
 If the Company will act as its own Paying Agent, it shall, on or before each due date of the principal of, premium, if any, or
interest on any of the Securities, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal, premium, if any, or interest so becoming due until such sums shall be paid to such Persons or

 The Company will cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section 8.3, that such Paying Agent will:

accordance with such provision and this Article Nine. 
  
 SECTION 9.3 Election to Redeem; Notice to Trustee.

  
 In case of any redemption at the election of the Company of any of the Securities, the Company shall, at least 35
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. 
  
 SECTION 9.4 Selection by Trustee of Securities to Be Redeemed. 
  
 If less than all the Securities are to be redeemed, the particular Securities to be redeemed shall be selected by the Trustee at least three Business Days prior to the date that the notice described in

 If any Registered 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 that have been converted during a selection of Securities to be redeemed may be treated by the Trustee as Outstanding for the purpose of such
selection. 
  
 The Trustee shall promptly notify the Company and each Security Registrar in writing of the Securities
selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount and certificate numbers 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

 
 53 

  
 redeemed only in part, to the portion of the principal amount of such Securities that has been or is to
be redeemed. 
  
 SECTION 9.5 Notice of Redemption. 
  
 Notice of redemption shall be given in the manner provided in Section 1.6 to the Holders of Securities to be redeemed not less than 30 nor more than 60 days prior to the

 (b) the Redemption Price, and accrued interest, if any, 
  

(c) if less than all Outstanding Securities are to be redeemed, the aggregate principal amount of Securities to be redeemed, 
  
 (d) that on the Redemption Date the Redemption Price, and accrued interest, if any, will become due and payable upon each
such Security to be redeemed, and that interest thereon shall cease to accrue on and after said date, 
  
 (e) the Conversion Rate, the date on which the right to convert the Securities to be redeemed will terminate and the places where such Securities may be surrendered for conversion, and 
  
 (f) the place or places where such Securities are to be surrendered for payment of the Redemption Price and accrued
interest, if any. 
  
 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 written request, by the Trustee in the name of and at the expense of the Company. 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. 
  
 SECTION 9.6 Deposit of Redemption
Price. 
  
 Not less than one Business Day prior to any Redemption Date, the Company shall deposit with the Trustee
(or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 8.3) an amount of money (which shall be in immediately available funds on such Redemption Date) 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 that are to be redeemed on that date other than any Securities called for redemption on that date that have been converted prior to the date of
such deposit. 

 
 54 

  
 If any Security called for redemption is converted, any money deposited with the
Trustee or so segregated and held in trust for the redemption of such Security shall (subject to any right of the Holder or such Security or any Predecessor Security to receive interest as provided in the last paragraph of Section 2.8) be paid to
the Company on Company Request or, if then held by the Company, shall be discharged from such trust. 
  
 SECTION 9.7
Securities Payable on Redemption Date. 
  
 Notice of redemption having been given as aforesaid, the Securities to be
so 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, including accrued interest) such
Securities shall cease to bear interest. Upon surrender of any Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price together with accrued and unpaid interest to the Redemption
Date; provided, however, that installments of interest on Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such on the
relevant Record Date according to their terms and the provisions of Section 2.8. 
  
 If any Security called for
redemption shall not be so paid upon surrender thereof for redemption, the principal amount of, premium, if any, and, to the extent permitted by applicable law, accrued interest on such Security shall, until paid, bear interest from the Redemption
Date at the rate then in effect, and such Security shall remain convertible until the principal of such Security (or portion thereof, as the case may be) shall have been paid or duly provided for. 
  
 SECTION 9.8 Securities Redeemed in Part. 
  
 Any Security that is to be redeemed only in part shall be surrendered at an office or agency of the Company designated for that purpose pursuant to Section 8.2 (with, if the Company or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and make available for delivery to the Holder of such Security without service charge, a new Registered Security or Securities, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and
in exchange for the unredeemed portion of the principal of the Security so surrendered. 
  
 SECTION 9.9 Conversion
Arrangement on Call for Redemption. 
  
 In connection with any redemption of the Securities, the Company may arrange
for the purchase and conversion of any Securities by an agreement with one or more investment bankers or other purchasers (the “Purchasers”) to purchase such Securities by paying to the Trustee in trust for the Holders, on or before the
Redemption Date, an amount not less than the applicable Redemption Price, together with interest accrued and unpaid to the Redemption Date, of such Securities. Notwithstanding anything to the contrary contained in this Article Nine, the obligation
of the 

 
 55 

  
 Company to pay the Redemption Price, together with interest accrued and unpaid to the Redemption Date,
shall be deemed to be satisfied and discharged to the extent such amount is so paid by such Purchasers. If such an agreement is entered into (a copy of which shall be filed with the Trustee prior to the close of business on the second Business Day
immediately prior to the Redemption Date), any Securities called for redemption that are not duly surrendered for conversion by the Holders thereof may, at the option of the Company, be deemed, to the fullest extent permitted by law, and consistent
with any agreement or agreements with such Purchasers, to be acquired by such Purchasers from such Holders and (notwithstanding anything to the contrary contained in this Article Nine) surrendered by such Purchasers for conversion, all as of
immediately prior to the close of business on the Redemption Date (and the right to convert any such Securities shall be extended through such time), subject to payment of the above amount as aforesaid. At the direction of the Company, the Trustee
shall hold and dispose of any such amount paid to it by the Purchasers to the Holders in the same manner as it would monies deposited with it by the Company for the redemption of Securities. Without the Trustee’s prior written consent, no
arrangement between the Company and such Purchasers for the purchase and conversion of any Securities shall increase or otherwise affect any of the powers, duties, responsibilities or obligations of the Trustee as set forth in this Indenture, and
the Company agrees to indemnify the Trustee from, and hold it harmless against, any loss, liability or expense arising out of or in connection with any such arrangement for the purchase and conversion of any Securities between the Company and such
Purchasers, including the costs and expenses, including reasonable legal fees, incurred by the Trustee in the defense of any claim or liability arising out of or in connection with the exercise or performance of any of its powers, duties,
responsibilities or obligations under this Indenture.

 CONVERSION OF SECURITIES 
  
 SECTION 10.1 Conversion Privilege and Conversion Rate. 
  
 Subject to and upon compliance with the provisions of this Article, at the option of the Holder thereof, any Security or any portion of the principal amount thereof that is U.S.$l,000 or an integral multiple of U.S.$1,000
may be converted into fully paid and nonassessable shares (calculated as to each conversion to the nearest 1/100th of a share) of Common Stock of the Company at the Conversion Rate, determined as hereinafter provided, in effect at the time of
conversion. Such conversion right shall commence upon the original issuance of the Securities and expire at the close of business on June 15, 2008, unless the Security has been previously redeemed or repurchased, subject, in the case of conversion
of any Global Security, to any Applicable Procedures. In case a Security or portion thereof is called for redemption at the election of the Company or the Holder thereof exercises his right to require the Company to repurchase the Security, such
conversion right in respect of the Security, or portion thereof so called, shall expire at the close of business on the Business Day immediately preceding the Redemption Date or the Repurchase Date, as the case may be, unless the Company defaults in
making the payment due upon redemption or repurchase, as the case may be (in each case subject, as aforesaid, to any Applicable Procedures with respect to any Global Security). 
  

 
 56 

  
 The rate at which shares of Common Stock shall be delivered upon conversion
(herein called the “Conversion Rate”) shall be initially 100.0 shares of Common Stock for each U.S.$l,000 principal amount of Securities. The Conversion Rate shall be adjusted in certain instances as provided in this Article Ten.

  
 SECTION 10.2 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 8.2, accompanied by a duly signed and completed conversion notice substantially in the form attached hereto as Exhibit C stating 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. Each Security surrendered for conversion (in whole or in part) during the period from the close of business on any
Regular Record Date next preceding any Interest Payment Date to the opening of business on such Interest Payment Date shall (except in the case of any Security or portion thereof that has been called for redemption on a Redemption Date, or is to be
repurchased on a Repurchase Date, with the consequence that the conversion right of such Security would terminate between such Regular Record Date and the close of business on such Interest Payment Date) be accompanied by payment in New York
Clearing House funds or other funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount of such Security (or part thereof, as the case may be) being surrendered for conversion.
The interest so payable on such Interest Payment Date, with respect to any Security (or portion thereof, if applicable) that is surrendered for conversion during the period from the close of business on any Record Date next preceding any Interest
Payment Date to the opening of business on such Interest Payment Date, shall be paid to the Holder of such Security as of such Regular Record Date. Interest payable in respect of any Security surrendered for conversion on or after an Interest
Payment Date shall be paid to the Holder of such Security as of the next preceding Regular Record Date, notwithstanding the exercise of the right of conversion. Except as provided in this paragraph and subject to the last paragraph of Section 2.8,
no cash payment or adjustment shall be made upon any conversion on account of any interest accrued from the Interest Payment Date next preceding the conversion date, in respect of any Security (or part thereof, as the case may be) surrendered for
conversion, or on account of any dividends on the Common Stock issued upon conversion. The Company’s delivery to the Holder of the number of shares of Common Stock (and cash in lieu of fractions thereof, as provided in this Indenture) into
which a Security is convertible and any rights and warrants pursuant to Section 10.4(m) will be deemed to satisfy the Company’s obligation to pay the principal amount of the Security. 
  
 Securities shall be deemed to have been converted 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 deliver to the Trustee, for delivery to the Holder, a certificate or 
  

 
 57 

  
 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 10.3. 
  
 In the case of any Security that is
converted in part only, upon such conversion the Company shall execute and the Trustee shall authenticate and make available for delivery to the Holder thereof, at the expense of the Company, a new Registered Security or Securities of authorized
denominations in an aggregate principal amount equal to the unconverted portion of the principal amount of such Security. A Security may be converted in part, but only if the principal amount of such Security to be converted is any integral multiple
of U.S.$1,000 and the principal amount of such security to remain Outstanding after such conversion is equal to U.S.$l,000 or any integral multiple of U.S.$l,000 in excess thereof. 
  
 SECTION 10.3 Fractions of Shares. 
  
 No
fractional shares of Common Stock shall be issued upon conversion of any Security or Securities. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares that 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 that would otherwise be issuable upon conversion of
any Security or Securities (or specified portions thereof), the Company shall calculate and pay a cash adjustment in respect of such fraction (calculated to the nearest 1/100th of a share) in an amount equal to the same fraction of the Average Sales
Price Per Share at the close of business on the day of conversion. 
  
 SECTION 10.4 Adjustment of Conversion Rate.

  
 The Conversion Rate shall be subject to adjustments from time to time as follows: 
  
 (a) In case the Company shall pay or make a dividend or other distribution on any class of capital stock of the Company
payable in shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be increased by
dividing such Conversion Rate 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 increase to become effective (subject to paragraph (l) of this Section 10.4) immediately after the opening of business on the day following the date fixed
for such determination. For the purposes of this paragraph (a), 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. 
  

(b) 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 
  

 
 58 

  
 share less than the current market price per share (determined as provided in
paragraph (h) of this Section 10.4) of the Common Stock on the date fixed for the determination of stockholders entitled to receive such rights, options or warrants (other than any rights, options or warrants (1) that by their terms will also be
issued to any Holder upon conversion of a Security into shares of Common Stock without any action required by the Company or any other Person or (2) that are only exercisable upon the occurrence of specified triggering event and such triggering
event has not occurred), the Conversion Rate in effect at the opening of business on the day following the date fixed for such determination shall be increased by dividing such Conversion Rate by a fraction of which the numerator shall be the number
of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock which the aggregate of the offering price of the total number of shares of Common Stock so offered for
subscription or purchase would purchase at such current market price and the denominator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common
Stock so offered for subscription or purchase, such increase to become effective (subject to paragraph (l) of this Section 10.4) immediately after the opening of business on the day following the date fixed for such determination. For the purposes
of this paragraph (b), 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. 
  
 (c) In case outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Rate in effect at the
opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately increased, and, conversely, in case outstanding shares of Common Stock shall each be combined into a smaller number of shares of
Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately reduced, such increase or reduction, 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. 
  
 (d) 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 other property (including
cash or assets or securities, but excluding (1) any rights, options or warrants referred to in paragraph (b) of this Section 10.4 and the distribution of rights to all holders of Common Stock pursuant to the adoption of a stockholders’ rights
plan or the detachment of such rights under the terms of such stockholders’ rights plan, (2) any dividend or distribution paid in cash, except as set forth in paragraphs (e) and (f) of this Section 10.4, (3) any dividend or distribution
referred to in paragraph (a) of this Section 10.4 and (4) any merger or consolidation to which Section 10.11 applies), the Conversion Rate shall be adjusted so that the same shall equal the rate determined by dividing the Conversion Rate in effect
immediately prior to the close of business on the date fixed for the determination of stockholders entitled to receive such distribution by a fraction of which the numerator shall be the current market price per share (determined as provided in

 
 59 

  
 paragraph (h) of this Section 10.4) 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) 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 (subject to paragraph (l) of this Section 10.4) immediately prior to the
opening of business on the day following the date fixed for the determination of stockholders entitled to receive such distribution. 
  
 Under the provisions of the Company’s Rights Agreement dated as of November 11, 1996 and amended November 20, 2002 (the “Rights Plan”), between the Company and Computershare Investor
Services LLC, upon conversion of the Securities into Common Stock, to the extent that the Rights Plan is still in effect upon such conversion, the Holders of Securities will receive, in addition to the Common Stock, the rights described therein
(whether or not the rights have separated from the Common Stock at the tine of conversion), subject to the limitations set forth in the Rights Plan. In addition, if the Company implements a new rights plan (“New Rights Plan”), the Company
will provide under such New Rights Plan that the Holders of the Securities will receive, in addition to the Common Stock, the rights under the New Rights Plan (whether or not the rights under the New Rights Plan have separated from the Common Stock
at the time of conversion), subject to any limitations set forth in the New Rights Plan. 
  
 (e) In
case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock cash (excluding cash portions of distribution referred to in Section 10.4(d) and any cash that is distributed upon a merger or consolidation to which
Section 10.11 applies) in an aggregate amount that, combined together with (1) the aggregate amount of any other cash distributions to all holders of its Common Stock made exclusively in cash within the 365-day period preceding the date of payment
of such distribution and in respect of which no adjustment pursuant to this paragraph (e) has been made and (2) the aggregate of any cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive
and described in a Board Resolution) of consideration payable in respect of any tender offer by the Company or any Subsidiary for all or any portion of the Common Stock concluded within the 365-day period preceding the date of payment of such
distribution and in respect of which no adjustment pursuant to paragraph (f) of this Section 10.4 has been made (the “combined cash and tender amount”) exceeds 10% of the product of the current market price per share (determined as
provided in paragraph (h) of this Section 10.4) of the Common Stock on the date for the determination of holders of shares of Common Stock entitled to receive such distribution times the number of shares of Common Stock outstanding on such date (the
“aggregate current market price”), then, and in each such case, immediately after the close of business on such date for determination, subject to paragraph (l) of Section 10.4, the Conversion Rate shall be adjusted so that the same shall
equal the rate determined by dividing the Conversion Rate in effect immediately prior to the close of business on the date fixed for determination of the stockholders entitled to receive such distribution by a fraction (A) the numerator of which
shall be equal to the current market price per share (determined as provided in paragraph (h) of this Section 10.4) of the Common Stock on the date fixed for such determination less an amount equal to the quotient of (i) the excess of such combined
cash and tender amount over 
  

 
 60 

  
 10% of such aggregate current market price divided by (ii) the number of shares
of Common Stock outstanding on such date fixed for determination and (B) the denominator of which shall be equal to the current market price per share (determined as provided in paragraph (h) of this Section 10.4) of the Common Stock on such date
fixed for determination. 
  
 (f) In case a tender offer made by the Company or any Subsidiary for all
or any portion of the Common Stock shall be completed for an aggregate consideration consisting of cash and/or property having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a
Board Resolution) that combined together with (1) the aggregate of the cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution), of consideration payable
in respect of any other tender offer by the Company or any Subsidiary for all or any portion of the Common Stock concluded within the 365-day period preceding the completion of such tender offer and in respect of which no adjustment pursuant to this
paragraph (f) has been made and (2) the aggregate amount of any distributions to all holders of the Company’s Common Stock made exclusively in cash within the 365-day period preceding the completion of such tender offer and in respect of which
no adjustment pursuant to paragraph (e) of this Section 10.4 has been made (the “combined tender and cash amount”) exceeds 10% of the product of the current market price per share of the Common Stock (determined as provided in paragraph
(h) of this Section 10.4) as of the completion of such tender offer (the “Completion Date”) times the number of shares of Common Stock outstanding (including any tendered shares) as of the Completion Date, then, and in each such case,
immediately prior to the opening of business on the day after the date of the Completion Date, the Conversion Rate shall be adjusted so that the same shall equal the rate determined by dividing the Conversion Rate immediately prior to close of
business on the Completion Date by a fraction (A) the numerator of which shall be equal to (i) the product of (x) the current market price per share of the Common Stock (determined as provided in paragraph (h) of this Section 10.4) on the Completion
Date multiplied by (y) the number of shares of Common Stock outstanding (including any tendered shares) on the Completion Date less (ii) the combined tender and cash amount, and (B) the denominator of which shall be equal to the product of (x) the
current market price per share of the Common Stock (determined as provided in paragraph (h) of this Section 10.4) as of the Completion Date multiplied by (y) the number of shares of Common Stock outstanding (including any tendered shares) as of the
Completion Date less the number of all shares validly tendered and not withdrawn as of the Completion Date (the shares deemed so accepted up to any such maximum, being referred to as the “Purchased Shares”). 
  
 (g) The reclassification of Common Stock into securities including other than Common Stock (other than any
reclassification upon a consolidation or merger to which Section 10.11 applies) shall be deemed to involve (1) a distribution of such securities other than Common Stock to all holders of Common Stock (and the effective date of such reclassification
shall be deemed to be “the date fixed for the determination of stockholders entitled to receive such distribution” and “the date fixed for such determination” within the meaning of paragraph (d) of this Section 10.4), and (2) 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 

 
 61 

  
 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 (c) of this Section 10.4).

  
 (h) For the purpose of any computation under paragraphs (b), (d), (e) or (f) of this Section
10.4, the current market price per share of Common Stock on any date shall be calculated by the Company and be deemed to be the average of the daily Average Sales Prices Per Share for the five consecutive Trading Days selected by the Company
commencing not more than 10 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 purposes of this
paragraph, the term “ex date,” when used with respect to any issuance or distribution, means the first date on which the Common Stock trades regular way in the applicable securities market or on the applicable securities exchange without
the right to receive such issuance or distribution. 
  
 (i) No adjustment in the Conversion Rate
shall be required unless such adjustment (plus any adjustments not previously made by reason of this paragraph (i)) would require an increase or decrease of at least one percent in such rate; provided, however, that any adjustments which by reason
of this paragraph (i) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article shall be made to the nearest cent or to the nearest one-hundredth of a share, as the
case may be. 
  
 (j) The Company may make such increases in the Conversion Rate, for the remaining
term of the Securities or any shorter term, in addition to those required by paragraphs (a), (b), (c), (d), (e) and (f) of this Section 10.4, as it considers to be advisable in order to avoid or diminish any income tax liability to any holders of
shares of Common Stock resulting from any dividend or distribution of Common Stock or issuance of rights or warrants to purchase or subscribe for Common Stock or from any event treated as such for income tax purposes. 
  
 To the extent permitted by applicable law, the Company from time to time may increase the Conversion Rate by any amount
for any period of time if the period is at least twenty (20) days and the Board of Directors shall have made a determination that such increase would be in the best interests of the Company, which determination shall be conclusive; provided,
however, that such increase shall not be taken into account for purposes of determining whether the Average Sales Price Per Share of the Common Stock exceeds the Conversion Price by 105% in connection with an event which would otherwise be a Change
in Control. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall give notice of the increase to the Holders of Securities in the manner provided in Section 1.6 at least fifteen (15) days prior to the date
the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect. 
  
 (k) Notwithstanding the foregoing provisions of this Section 10.4, no adjustment of the Conversion Rate shall be required to be made (1) upon the issuance
of shares of Common Stock pursuant to any present or future plan for the reinvestment of dividends, (2) because of a tender or exchange offer of the character described in Rule 13e-4(h)(5) under the Exchange Act or 
  

 
 62 

 any successor rule thereto or (3) as a result of a rights plan or poison pill implemented by the Company. 

 
 (l) In any case in which this Section 10.4 shall require that an adjustment be made immediately following a
record date, the Company may elect to defer the effectiveness of such adjustment (but in no event until a date later than the effective time of the event giving rise to such adjustment), in which case the Company shall, with respect to any Security
converted after such record date and on and before such adjustment shall have become effective (1) defer paying any cash payment pursuant to Section 10.3 hereof or issuing to the Holder of such Security the number of shares of Common Stock issuable
upon such conversion in excess of the number of shares of Common Stock issuable thereupon only on the basis of the Conversion Rate prior to adjustment, and (2) not later than five Business Days after such adjustment shall have become effective, pay
to such Holder the appropriate cash payment pursuant to Section 10.3 hereof and issue to such Holder the additional shares of Common Stock issuable on such conversion. Notwithstanding the foregoing, no adjustment of the Conversion Rate shall be made
if the event giving rise to such adjustment does not occur. 
  
 (m) In the event that the Company
distributes rights or warrants (other than those referred to in paragraph (b) above) pro rata to holders of Common Stock, so long as any such rights or warrants have not expired or been redeemed by the Company, the Company shall make proper
provision so that the Holder of any Security surrendered for conversion will be entitled to receive upon such conversion, in addition to the Common Stock issuable upon conversion of the Securities (the “Conversion Shares”), a number of
rights and warrants to be determined as follows: (i) if such conversion occurs on or prior to the date for the distribution to the holders of rights or warrants of separate certificates evidencing such rights or warrants (the “Distribution
Date”), the same number of rights or warrants to which a holder of a number of shares of Common Stock equal to the number of Conversion Shares is entitled at the time of such conversion in accordance with the terms and provisions of and
applicable to the rights or warrants, and (ii) if such conversion occurs after such Distribution Date, the same number of rights or warrants to which a holder of the number of shares of Common Stock into which the principal amount of such Security
so converted was convertible immediately prior to such Distribution Date would have been entitled on such Distribution Date in accordance with the terms and provisions of and applicable to the rights or warrants. 
  
 SECTION 10.5 Notice of Adjustments of Conversion Rate. 
  
 Whenever the Conversion Rate is adjusted as herein provided: 
  
 (a) the Company shall compute the adjusted Conversion Rate in accordance with Section 10.4 and shall prepare a certificate signed by the Chief Financial Officer of the Company setting forth the
adjusted Conversion Rate and showing in reasonable detail the facts upon which such adjustment is based, and such certificate shall promptly be filed with the Trustee and with the Conversion Agent; and 
  
 (b) upon each such adjustment, a notice stating that the Conversion Rate has been adjusted and setting forth the adjusted
Conversion Rate shall be required, and as soon as practicable 
  

 
 63 

 after it is required, such notice shall be provided by the Company to all Holders in accordance with Section 1.6.

  
 Neither the Trustee nor the Conversion Agent shall be under any duty or responsibility with respect to any such
certificate or the information and calculations contained therein, except to exhibit the same to any Holder of Securities desiring inspection thereof at its office during normal business hours. Unless and until a Responsible Officer of the Trustee
and Conversion Agent receive notice of an adjusted Conversion Rate, the Trustee and the Conversion Agent may rely without inquiry on the Conversion Rate most recently in effect. 
  
 SECTION 10.6 Notice of Certain Corporate Action. 
  
 In case: 
  
 (a) the Company shall declare a dividend (or any other distribution) on
its Common Stock payable (i) otherwise than exclusively in cash or (ii) exclusively in cash in an amount that would require any adjustment pursuant to Section 10.4; or 
  
 (b) the Company shall authorize the granting to the holders of its Common Stock of rights, options or warrants to subscribe for or purchase any shares of
capital stock of any class or of any other rights; or 
  
 (c) of any reclassification of the Common
Stock of the Company, or of any consolidation, merger or share exchange to which the Company is a party and for which approval of any stockholders of the Company is required, or of the conveyance, sale, transfer or lease of all or substantially all
of the assets of the Company; or 
  
 (d) of the voluntary or involuntary dissolution, liquidation or
winding up of the Company; 
  
 then the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of
Securities pursuant to Section 8.2, and shall cause to be provided to all Holders in accordance with Section 1.6, at least 20 days (or 10 days in any case specified in clause (a) or (b) above) prior to the applicable record or effective date
hereinafter specified, a notice stating (1) the date on which a record is to be taken for the purpose of such dividend, distribution, rights, options 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, options or warrants are to be determined or (2) the date on which such reclassification, consolidation, merger, conveyance, transfer, sale, lease, 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, conveyance, transfer, sale, lease, dissolution, liquidation or winding up. Neither the failure to give such notice or the notice referred to in the following paragraph nor any defect therein shall affect the
legality or validity of the proceedings described in clauses (a) through 

 
 64 

 (d) of this Section 10.6. If at the time the Trustee shall not be the Conversion Agent, a copy of such notice shall also forthwith be filed by
the Company with the Trustee. 
  
 The Company shall cause to be filed at each office or agency maintained for the
purpose of conversion of Securities pursuant to Section 8.2, and shall cause to be provided to all Holders in accordance with Section 1.6, notice of any tender offer by the Company or any Subsidiary for all or any portion of the Common Stock at or
about the time that such notice of tender offer is provided to the public generally. 
  
 SECTION 10.7 Company to
Reserve Common Stock. 
  
 The Company shall at all times reserve and keep available, free from preemptive rights, out
of its authorized but unissued Common Stock, for the purpose of effecting the conversion of Securities, the full number of shares of Common Stock then issuable upon the conversion of all Outstanding Securities. 
  
 SECTION 10.8 Taxes on Conversions. 
  
 Except as provided in the next sentence, the Company will pay any and all taxes and duties 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 or duty 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 duty or has established to the satisfaction of the Company that such
tax or duty has been paid. 
  
 SECTION 10.9 Covenant as to Common Stock. 
  
 The Company agrees that all shares of Common Stock that may be delivered upon conversion of Securities, upon such delivery, will be newly
issued shares and will have been duly authorized and validly issued and will be fully paid and nonassessable and, except as provided in Section 10.8, the Company will pay all taxes, liens and charges with respect to the issue thereof. 

 
 SECTION 10.10 Cancellation of Converted Securities. 
  
 All Securities delivered for conversion shall be delivered to the Trustee or its agent to be cancelled by or at the direction of the Trustee, which shall dispose of the
same as provided in Section 2.10. 
  
 SECTION 10.11 Provision in Case of Consolidation, Merger or Sale of Assets.

  
 In case of any consolidation or merger of the Company with or into any other Person, any merger of another Person
with or into the Company (other than a merger that does not result in any reclassification, conversion, exchange or cancellation of outstanding shares of Common Stock of the 
  

 
 65 

 Company) or any conveyance, sale, transfer or lease of all or substantially all of the assets of the Company, the Person formed by such
consolidation or resulting from such merger or that acquires such assets, as the case may be, shall execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Security then Outstanding shall have the right
thereafter, during the period such Security shall be convertible as specified in Section 11.1, to convert such Security only into the kind and amount of securities, cash and other property receivable upon such consolidation, merger, conveyance,
sale, transfer or lease by a holder of the number of shares of Common Stock of the Company into which such Security might have been converted immediately prior to such consolidation, merger, conveyance, sale, transfer or lease, assuming such holder
of Common Stock of the Company (a) is not a Person with which the Company consolidated or merged with or into or that 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 an Affiliate of a Constituent Person and (b) failed to exercise his rights of election, if any, as to the kind or amount of securities, cash and other property receivable upon such consolidation, merger,
conveyance, sale, transfer or lease (provided that if the kind or amount of securities, cash and other property receivable upon such consolidation, merger, conveyance, sale, transfer, or lease is not the same for each share of Common Stock of the
Company held immediately prior to such consolidation, merger, conveyance, sale, transfer or lease by others than a Constituent Person or an Affiliate thereof and in respect of which such rights of election shall not have been exercised
(“Non-electing Share”), then for the purpose of this Section 10.11 the kind and amount of securities, cash and other property receivable upon such consolidation, merger, conveyance, sale, transfer or lease by the holders of 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 that, 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 10.11 shall similarly apply to successive consolidations, mergers, conveyances, sales,
transfers or leases. Notice of the execution of such a supplemental indenture shall be given by the Company to the Holder of each Security as provided in Section 1.6 promptly upon such execution. 
  

Neither the Trustee nor the Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any such supplemental
indenture relating either to the kind or amount of shares of stock or other securities or property or cash receivable by Holders of Securities upon the conversion of their Securities after any such consolidation, merger, conveyance, transfer, sale
or lease or to any such adjustment but may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, an Officers Certificate or an Opinion of Counsel with respect thereto, which the Company
shall cause to be furnished to the Trustee upon request. 
  
 SECTION 10.12 Responsibility of Trustee for Conversion
Provisions. 
  
 The Trustee, subject to the provisions of Section 5.1, and any Conversion Agent shall not at any time
be under any duty or responsibility to any Holder of Securities to determine whether any facts exist that may require any adjustment of the Conversion Rate, or with respect to the nature or extent of any such adjustment when made, or with respect to
the method employed, or herein or in 

 
 66 

 any supplemental indenture provided to be employed, in making the same, or whether a supplemental indenture need be entered into. Neither the
Trustee, subject to the provisions of Section 5.1, nor any Conversion Agent shall be accountable with respect to the validity or value (or the kind or amount) of any Common Stock, or of any other securities or property or cash, that may at any time
be issued or delivered upon the conversion of any Security; and it or they do not make any representation with respect thereto. Neither the Trustee, subject to the provisions of Section 5.1, nor any Conversion Agent shall be responsible for any
failure of the Company to make or calculate any cash payment or to issue, transfer or deliver any shares of Common Stock or share certificates or other securities or property or cash upon the surrender of any Security for the purpose of conversion;
and the Trustee, subject to the provisions of Section 5.1, and any Conversion Agent shall not be responsible for any failure of the Company to comply with any of the covenants of the Company contained in this Article. 
  
  
 ARTICLE ELEVEN 
  
 SUBORDINATION OF SECURITIES 
  
 SECTION 11.1 Securities
Subordinate to Senior Debt. 
  
 The Company covenants and agrees, and each Holder of a Security by his acceptance
thereof likewise covenants and agrees, that to the extent and in the manner hereinafter set forth in this Article (subject to the provisions of Article Three) the indebtedness represented by the Securities and the payment of the principal of (and
premium, if any) and interest on, and any payment of the Repurchase Price with respect to, each and all of the Securities are hereby expressly made subordinate and subject in right of payment to the prior payment in full in cash or Cash Equivalents
of all Senior Debt. 
  
 SECTION 11.2 No Payments in Certain Circumstances; Payment Over of Proceeds Upon Dissolution,
Etc. 
  
 No payment on account of principal of, premium, if any, or interest on, or redemption or repurchase of, the
Securities shall be made if, at the time of such payment: (a) a default in the payment of principal, premium, if any, or interest or other amounts due on or in connection with any Senior Debt, including any default under any redemption or repurchase
obligation, occurs and is continuing (or, in the case of Senior Debt for which there is a period of grace, in the event of such a default that continues beyond the period of grace, if any, specified in the instrument or lease evidencing such Senior
Debt), unless and until such default shall have been cured or waived or shall have ceased to exist; or (b) a default, other than a payment default, on Designated Senior Debt occurs and is continuing that then permits holders of such Designated
Senior Debt to accelerate its maturity and the Trustee receives a notice of the default (a “Payment Blockage Notice”) from the Company, a holder of Designated Senior Debt or a Representative. Notwithstanding the foregoing, the Company may
make, and the Trustee may receive and shall apply, any payment in respect of the Securities (for principal, premium, if any, or interest or repurchase) if such payment was made prior to the occurrence of any of the contingencies specified in clauses
(a) and (b) above. 

 
 67 

  
 If the Trustee receives any Payment Blockage Notice pursuant to clause (b) above,
no subsequent Payment Blockage Notice shall be effective for purposes of this Section 11.2 unless and until (1) at least 365 days shall have elapsed since the effectiveness of the immediately prior Payment Blockage Notice and (2) all scheduled
payments of principal, premium, if any, and interest on the Securities that have come due have been paid in full in cash. No nonpayment default that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Trustee
shall be, or be made, the basis for a subsequent Payment Blockage Notice unless such existing nonpayment default has been cured for a period of at least 90 days. 
  
 The Company may and shall resume payments on and distributions in respect of the Securities (including missed payments, if any) upon the earlier of: (A) the date upon which the default is cured or
waived, or (B) in the case of a default referred to in clause (b) of the second preceding paragraph, 179 days after notice is received if the maturity of such Designated Senior Debt has not been accelerated such that such debt is then presently
payable, unless this Indenture otherwise prohibits the payment or distribution at the time of such payment or distribution. 
  
 Upon (i) any acceleration of the principal amount due on the Securities or (ii) any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to creditors upon any
dissolution, winding up or total or partial liquidation or reorganization of the Company, whether voluntary or involuntary, or in bankruptcy, insolvency, receivership or other proceedings, all principal of, premium, if any, sinking fund and interest
or other amounts due, or to become due, upon or in connection with all Senior Debt shall first be paid in full in cash or Cash Equivalents, or payment thereof provided for in cash or Cash Equivalents in accordance with its terms, before any payment
is made on account of the principal of, premium, if any, or interest on, or repurchase of, the indebtedness evidenced by the Securities, and upon any such dissolution or winding up or liquidation or reorganization any payment or distribution of
assets of the Company of any kind or character, whether in cash, property or securities, to which the Holders of the Securities or the Trustee under this Indenture would be entitled, except for the provisions hereof, shall be paid by the Company or
by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, or by the Holders of the Securities or by the Trustee under this Indenture if received by them or it, as the case may be,
directly to the holders of Senior Debt (pro rata to each such holder on the basis of the respective amounts of Senior Debt held by such holder) or their representatives, to the extent necessary to pay all Senior Debt in full, in cash or Cash
Equivalents, after giving effect to any concurrent payment or distribution to or for the holders of Senior Debt, before any payment or distribution is made to the Holders of the Securities or to the Trustee under this Indenture. 

 
 In the event that, contrary to the foregoing, any payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities (other than junior securities, as defined in Section 11.11), shall be received by the Trustee or the Holders of the Securities before all Senior Debt is paid in full in cash or Cash Equivalents or provision
made for such payment in accordance with its terms, such payment or distribution shall be paid over or delivered to the holders of such Senior Debt or their representative or representatives, or to the trustee or trustees under any indenture
pursuant to which any instruments evidencing any of such 

 
 68 

 Senior Debt have been issued, as their respective interests may appear, for application to the payment of all Senior Debt remaining unpaid to
the extent necessary to pay all such Senior Debt in full in cash or Cash Equivalents in accordance with its terms, after giving effect to any concurrent payment or distribution to or for the holders of such Senior Debt. 
  
 Subject to the payment in full in cash or Cash Equivalents of all Senior Debt, the Holders of the Securities (together with the holders of
any other indebtedness of the Company that is subordinated in right of payment to the payment in full of all Senior Debt that is not subordinated in right of payment to the Securities and that by its terms grants such right of subrogation to the
holders thereof) shall be subrogated to the rights of the holders of Senior Debt to receive payments or distribution of assets of the Company made on the Senior Debt until the principal of, premium, if any, and interest on, or amounts payable upon
repurchase of, the Securities shall be paid in full; and, for the purposes of such subrogation, no payments or distributions to the holders of Senior Debt of any cash, property or securities to which the Holders of the Securities or the Trustee
would be entitled except for the provisions of this Article, and no payment over pursuant to the provisions of this Article to the holders of Senior Debt by the Holders of the Securities or the Trustee, shall, as between the Company, its creditors
other than the holders of Senior Debt, and the Holders of Securities, be deemed to be a payment by the Company to the holders of or on account of Senior Debt, it being understood that the provisions of this Article are and are intended solely for
the purpose of defining the relative rights of the Holders of the Securities, on the one hand, and the holders of Senior Debt, on the other hand. 
  
 SECTION 11.3 Trustee to Effectuate Subordination. 
  
 Each Holder of
a Security by his acceptance thereof authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article and appoints the Trustee his attorney-in-fact for
any and all such purposes. 
  
 SECTION 11.4 No Waiver of Subordination Provisions. 
  
 No right of any present or future holder of any Senior Debt to enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder of any Senior Debt or by any non-compliance by the Company with the terms, provisions and covenants of
this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with. 
  
 Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Debt may, at any time and from time to time, without the consent of or notice to the Trustee or the Holders of the Securities, without
incurring responsibility to the Holders of the Securities and without impairing or releasing the subordination provided in this Article or the obligations hereunder of the Holders of the Securities to the holders of Senior Debt, do any one or more
of the following: (a) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, Senior Debt or otherwise amend or supplement in any manner Senior Debt or any instrument evidencing the same or any agreement
under which Senior Debt is outstanding; (b) sell, exchange, 

 
 69 

 release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Debt; (c) release any Person liable in any manner
for the collection of Senior Debt; and (d) exercise or refrain from exercising any rights against the Company and any other Person. 
  
 SECTION 11.5 Notice to Trustee. 
  
 The Company shall give prompt written notice to the
Trustee of any fact known to the Company that would prohibit the making of any payment to or by the Trustee in respect of the Securities. Notwithstanding the provisions of this Article or any other provision of this Indenture, the Trustee shall not
be charged with knowledge of the existence of any facts that would prohibit the making of any payment to or by the Trustee in respect of the Securities, unless and until a Responsible Officer of the Trustee shall have received written notice thereof
from the Company or a holder of Senior Debt or from any trustee, agent or representative therefor; and, prior to the receipt of any such written notice, the Trustee, subject to the provisions of Section 5.1, shall be entitled in all respects to
assume that no such facts exist; provided, however, that if the Trustee shall not have received the notice provided for in this Section 11.5 prior to the date upon which by the terms hereof any money may become payable for any purpose (including
without limitation the payment of the principal of (and premium, if any) or interest on any Security), then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such money and to
apply the same to the purpose for which such money was received and shall not be affected by any notice to the contrary that may be received by it within two Business Days prior to such date. 
  

Subject to the provisions of Section 5.1, the Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing himself to be a
holder of Senior Debt (or a trustee, agent or representative therefor) to establish that such notice has been given by a holder of Senior Debt (or a trustee, agent or representative therefor). In the event that the Trustee determines in good faith
that further evidence is required with respect to the right of any Person as a holder of Senior Debt to participate in any payment or distribution pursuant to this Article Eleven, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Debt held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under
this Article Eleven, and if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. 
  

SECTION 11.6 Reliance on Judicial Order or Certificate of Liquidating Agent. 
  
 Upon any payment or distribution of assets of the Company referred to in this Article, the Trustee, subject to the provisions of Section 5.1, and the Holders of the Securities shall be entitled to rely
upon any order or decree entered by any court of competent jurisdiction in which such insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution, winding up or similar case or proceeding is pending, or a certificate of the
trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit of creditors, agent or other Person making such payment or distribution, delivered to the Trustee or to the Holders of Securities, for the purpose of
ascertaining the Persons entitled to participate in such payment or distribution, the holders of the 

 
 70 

 Senior Debt and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and
all other facts pertinent thereto or to this Article. 
  
 SECTION 11.7 Trustee Not Fiduciary for Holders of Senior
Debt. 
  
 The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt and shall not be
liable to any such holders if it shall in good faith mistakenly pay over or distribute to Holders of Securities or to the Company or to any other Person cash, property or securities to which any holders of Senior Debt shall be entitled by virtue of
this Article or otherwise. With respect to the holders of Senior Debt, the Trustee undertakes to perform or to observe only such of its covenants or obligations as are specifically set forth in this Article Eleven, and no implied covenants or
obligations with respect to holders of Senior Debt shall be read into this Indenture against the Trustee. 
  
 SECTION
11.8 Reliance by Holders of Senior Debt on Subordination Provisions. 
  
 Each Holder by accepting a Security
acknowledges and agrees that the foregoing subordination provisions are, and are intended to be, an inducement and a consideration to each holder of any Senior Debt, whether such Senior Debt was created or acquired before or after the issuance of
the Securities, to acquire and continue to hold, or to continue to hold, such Senior Debt, and such holder of Senior Debt shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold, or in
continuing to hold, such Senior Debt. Such holders of the Company’s Senior Debt are intended by the parties to the Indenture to be third party creditor beneficiaries under this Indenture for the purposes of enforcing the provisions of this
Article Eleven. 
  
 SECTION 11.9 Rights of Trustee as Holder of Senior Debt; Preservation of Trustee’s Rights.

  
 The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article Eleven with
respect to any Senior Debt that may at any time be held by it, to the same extent as any other holder of Senior Debt, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. 
  
 Nothing in this Article Eleven shall apply to claims of, or payments to, the Trustee under or pursuant to Section 5.7. 

 
 SECTION 11.10 Article Applicable to Paying Agents. 
  
 In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term “Trustee” as used in
this Article shall in such case (unless the context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article Eleven
in addition to or in place of the Trustee; provided, however, that Section 11.9 

 
 71 

 shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as Paying Agent. 
  
 SECTION 11.11 Certain Conversions and Repurchases Deemed Payment. 
  
 For the purposes of this Article Eleven only, (a) the issuance and delivery of junior securities upon conversion of Securities in accordance with Article Ten or upon the
repurchase of Securities in accordance with Article Twelve shall not be deemed to constitute a payment or distribution on account of the principal of or premium or interest on Securities or on account of the purchase or other acquisition of
Securities, and (b) the payment, issuance or delivery of cash, property or securities (other than junior securities) upon conversion of a Security shall be deemed to constitute payment on account of the principal of such Security. For the purposes
of this Section 11.11, the term “junior securities” means (1) shares of any stock of any class of the Company and any cash, property or securities into which the Securities are convertible pursuant to Article Ten and (2) securities of the
Company that are subordinated in right of payment to all Senior Debt that may be outstanding at the time of issuance or delivery of such securities to substantially the same extent as, or to a greater extent than, the Securities are so subordinated
as provided in this Article Eleven. Nothing contained in this Article Eleven or elsewhere in this Indenture or in the Securities is intended to or shall impair, as among the Company, its creditors other than holders of Senior Debt and the Holders of
the Securities, the right, which is absolute and unconditional, of the Holder of any Security to convert such Security in accordance with Article Ten or to exchange such Security for Common Stock in accordance with Article Twelve if the Company
elects to satisfy the obligations under Article Twelve by the delivery of Common Stock. 
  
  
 ARTICLE TWELVE 
  
 REPURCHASE OF SECURITIES AT THE OPTION OF 
 THE HOLDER UPON A CHANGE IN CONTROL 
  
 SECTION 12.1 Right to Require Repurchase. 
  
 In the event that a Change in Control shall occur, then
each Holder shall have the right, at the Holder’s option, but subject to the provisions of Section 12.2, to require the Company to repurchase, and upon the exercise of such right the Company shall repurchase, all of such Holder’s
Securities not theretofore called for redemption, or any portion of the principal amount thereof that is equal to U.S.$1,000 or any greater integral multiple of U.S.$1,000, on the date (the “Repurchase Date”) that is fixed by the Company
at a cash purchase price equal to 100% of the principal amount of the Securities to be repurchased plus interest accrued to the Repurchase Date (the “Repurchase Price”); provided, however, that installments of interest on Securities whose
Stated Maturity is on or prior to the Repurchase Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such on the relevant Record Date according to their terms and the provisions of Section
2.8. The Repurchase Date will be determined by the Company in the following manner: (i) the Company will give notice of the Change in Control as contemplated in Section 12.3(a); (ii) each Holder electing to exercise the repurchase right must
deliver, on or before the thirtieth (30th) day (or such greater period as may be required by applicable law) after the date of the 

 
 72 

 Company’s notice provided in provision (i) above: (A) irrevocable written notice to the trustee of such Holder’s exercise of its
repurchase right, and (B) the Securities with respect to which such repurchase right is being exercised; and (iii) the Company will make the repurchase on a date that is no later than 45 days after the Holder has delivered the notice provided in
proviso (ii) above. Such right to require the repurchase of the Securities shall not continue after a discharge of the Company from its obligations with respect to the Securities in accordance with Article Three unless a Change in Control shall have
occurred prior to such discharge. At the option of the Company, the Repurchase Price may be paid in cash or, subject to the fulfillment by the Company of the conditions set forth Section 12.2, by delivery of shares of Common Stock or in a
combination of cash and Common Stock having a fair market value equal to the Repurchase Price. Whenever in this Indenture (including Sections 2.2, 4.1(a) and 4.8) there is a reference, in any context, to the principal of any Security as of any time,
such reference shall be deemed to include reference to the Repurchase Price that has become and remains payable in respect of such Security to the extent that such Repurchase Price is, was or would be so payable at such time, and express mention of
the Repurchase Price in any provision of this Indenture shall not be construed as excluding the Repurchase Price in those provisions of this Indenture when such express mention is not made; provided, however, that for the purposes of Article Eleven
such reference shall be deemed to include reference to the Repurchase Price only to the extent the Repurchase Price is payable in cash. 
  
 For purposes of this Section 12.1, the fair market value of shares of Common Stock shall be determined by the Company and shall be equal to 95% of the average of the closing price per share of the Common Stock or the
principal exchange on which the Common Stock is traded in on The Nasdaq National Market for each of the five consecutive Trading Days immediately preceding and including the third Trading Day prior to the Repurchase Date. 
  
 SECTION 12.2 Conditions to the Company’s Election to Pay the Repurchase Price in Common Stock. 
  
 The Company may elect to pay the Repurchase Price by delivery of shares of Common Stock pursuant to Section 12.1 if and only if the
following conditions shall have been satisfied: 
  
 (a) As to each Holder, the Repurchase Price shall
be paid only in cash in the event any shares of Common Stock to be issued to such Holder upon repurchase of Securities hereunder (1) require registration under any federal securities law before such shares may be freely transferable without being
subject to any transfer restrictions under the Securities Act upon repurchase and if such registration is not completed or does not become effective prior to the Repurchase Date or (2) require registration with or approval of any governmental
authority under any state law or any other federal law before such shares may be validly issued or delivered upon repurchase and if such registration is not completed or does not become effective or such approval is not obtained prior to the
Repurchase Date; 
  
 (b) Payment of the Repurchase Price may not be made in Common Stock unless such
stock is, or shall have been, approved for quotation on The Nasdaq National Market or listed or quoted on a national securities exchange or other quotation system, in either case, prior to the Repurchase Date; and 

 
 73 

  
 (c) All shares of Common Stock that may be issued upon repurchase
of Securities will be issued out of the Company’s authorized but unissued Common Stock will and, upon issue, be duly and validly issued and fully paid and non-assessable and free of any preemptive rights. 
  
 If all of the conditions set forth in this Section 12.2 are not satisfied in accordance with the terms thereof, the Repurchase Price shall
be paid by the Company only in cash. 
  
 SECTION 12.3 Notices; Method of Exercising Repurchase Right, Etc.

  
 (a) Unless the Company shall have theretofore called for redemption all of the Outstanding Securities, on or
before the thirtieth day after the occurrence of a Change in Control, the Company or, at the request and expense of the Company on or before the thirtieth day after such occurrence, the Trustee, shall give to all Holders of Securities, in the manner
provided in Section 1.6, notice (the “Company Notice”) of the occurrence of the Change in Control and of the repurchase right set forth herein arising as a result thereof. The Company shall also deliver a copy of such notice of a
repurchase right to the Trustee. 
  
 Each notice of a repurchase right shall state: 
  
 (1) the Repurchase Date, 
  
 (2) the date by which the repurchase right must be exercised, 
  
 (3) the Repurchase Price, and whether the Repurchase Price shall be paid by the Company in cash or by delivery of shares of Common Stock, 

 
 (4) a description of the procedure that a Holder must follow to exercise a repurchase right, and the place or
places where such Securities are to be surrendered for payment of the Repurchase Price and accrued interest, if any, 
  
 (5) that on the Repurchase Date, the Repurchase Price, and accrued interest, if any, will become due and payable upon each such Security designated by the Holder to be repurchased and that interest thereon shall cease to
accrue on and after said date, 
  
 (6) the Conversion Rate then in effect, the date on which the
right to convert the principal amount of the Securities to be repurchased will terminate and the place or places where such Securities may be surrendered for conversion, 
  
 (7) the place or places that the Notice of Election of Holder to Require Repurchase attached hereto as Exhibit B, shall be delivered, and the form of such
notice, and 
  
 (8) the CUSIP number or numbers of such Securities. 
  
 No failure of the Company to give the foregoing notices or defect therein shall limit any Holder’s right to exercise a repurchase
right or affect the validity of the proceedings for the repurchase of Securities. 

 
 74 

  
 If any of the foregoing provisions or other provisions of this Article Twelve are
inconsistent with applicable law, such law shall govern. 
  
 (b) To exercise a repurchase right, a Holder shall
deliver to the Trustee on or before the thirtieth day (or such greater period as may be required by applicable law) after the date of the Company Notice (1) written notice of the Holder’s exercise of such right, which notice shall set forth the
name of the Holder, the principal amount of the Securities to be repurchased (and, if any Security is to repurchased in part, the serial number thereof, the portion of the principal amount thereof to be repurchased and the name of the Person in
which the portion thereof to remain Outstanding after such repurchase is to be registered) and a statement that an election to exercise the repurchase right is being made thereby, and, in the event that the Repurchase Price shall be paid in shares
of Common Stock, the name or names (with addresses) in which the certificate or certificates for shares of Common Stock shall be issued, and (2) the Securities with respect to which the repurchase right is being exercised. Such written notice shall
be irrevocable, except that the right of the Holder to convert the Securities with respect to which the repurchase right is being exercised shall continue until the close of business on the Business Day immediately preceding the Repurchase Date.

  
 (c) In the event a repurchase right shall be exercised in accordance with the terms hereof, the Company shall pay
or cause to be paid to the Trustee the Repurchase Price in cash or shares of Common Stock, as provided above, for payment to the Holder on the Repurchase Date or, if shares of Common Stock are to be paid, as promptly after the Repurchase Date as
practicable, together with accrued and unpaid interest to the Repurchase Date payable with respect to the Securities as to which the purchase right has been exercised; provided, however, that installments of interest that mature on or prior to the
Repurchase Date shall be payable in cash to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Regular Record Date. 
  

(d) If any Security (or portion thereof) surrendered for repurchase shall not be so paid on the Repurchase Date, the principal amount of such Security (or portion
thereof, as the case may be) shall, until paid, bear interest to the extent permitted by applicable law from the Repurchase Date at the rate then in effect per annum, and each Security shall remain convertible into Common Stock until the principal
of such Security (or portion thereof, as the case may be) shall have been paid or duly provided for. 
  
 (e) Any
Security that is to be repurchased only in part shall be surrendered to the Trustee (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly
executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Security without service charge, a new Security or
Securities, containing identical terms and conditions, each in an authorized denomination in aggregate principal amount equal to and in exchange for the unrepurchased portion of the principal of the Security so surrendered. 

 
 75 

  
 (f) Any issuance of shares of Common Stock in respect of the Repurchase Price
shall be deemed to have been effected immediately prior to the close of business on the Repurchase Date and the Person or Persons in whose name or names any certificate or certificates for shares of Common Stock shall be issuable upon such
repurchase shall be deemed to have become on the Repurchase Date the holder or holders of record of the shares represented thereby; provided, however, that any surrender for repurchase on a date when the stock transfer books of the Company shall be
closed shall constitute the Person or Persons in whose name or names the certificate or certificates for such shares are to be issued as the record holder or holders thereof for all purposes at the opening of business on the next succeeding day on
which such stock transfer books are open. No payment or adjustment shall be made for dividends or distributions on any Common Stock issued upon repurchase of any Security declared prior to the Repurchase Date. 
  
 (g) No fractions of shares shall be issued upon repurchase of Securities. If more than one Security shall be repurchased from the same
Holder and the Repurchase Price shall be payable in shares of Common Stock, the number of full shares that shall be issuable upon such repurchase shall be computed on the basis of the aggregate principal amount of the Securities so repurchased.
Instead of any fractional share of Common Stock that would otherwise be issuable on the repurchase of any Security or Securities, the Company will deliver to the applicable Holder its check for the current market value of such fractional share. The
current market value of a fraction of a share is determined by multiplying the current market price of a full share by the fraction and rounding the result to the nearest cent. For purposes of this Section 12.3, the current market price of a share
of Common Stock is the average of the high and low sales price per Share of the Common Stock on the Trading Day immediately preceding the Repurchase Date. 
  
 (h) Any issuance and delivery of certificates for shares of Common Stock on repurchase of Securities shall be made without charge to the Holder of Securities being repurchased for such certificates or
for any tax or duty in respect of the issuance or delivery of such certificates or the securities represented thereby; provided, however, that the Company shall not be required to pay any tax or duty that may be payable in respect of (1) income of
the Holder or (2) any transfer involved in the issuance or delivery of certificates for shares of Common Stock in a name other than that of the Holder of the Securities being repurchased, and no such issuance or delivery shall be made unless and
until the Person requesting such issuance or delivery has paid to the Company the amount of any such tax or duty or has established, to the satisfaction of the Company, that such tax or duty has been paid. 
  
 (i) All Securities delivered for repurchase shall be delivered to the Trustee to be canceled at the direction of the Trustee, which shall
dispose of the same as provided in Section 2.10.

reasonably require, of the names and addresses of the Holders of Securities as of such Regular Record Date, and 
  
 (b) at such other times as the Trustee may reasonably request in writing, within 30 days after the receipt by the Company of any such request, a list of similar form and content as of a date not more than 15 days prior to the time
such list is furnished; 
  
 provided, however, that no such list need be furnished so long as the Trustee is acting as Security Registrar.

 (a) The Trustee shall preserve, in as current a form as is reasonably practicable, the names and addresses of Holders contained in the most recent list furnished to the
Trustee as provided in Section 13.1 and the names and addresses of Holders received by the Trustee in its capacity as Security Registrar. The Trustee may destroy any list furnished to it as provided in Section 13.1 upon receipt of a new list so

 (b) After this Indenture has been qualified under the Trust Indenture Act, the rights of Holders to
communicate with other Holders with respect to their rights under this Indenture or under the Securities, and the corresponding rights and duties of the Trustee, shall be as provided by the Trust Indenture Act. 
  
 (c) Every Holder of Securities, by receiving and holding the same, agrees with the Company and the Trustee that neither the Company nor
the Trustee nor any agent of either of them shall be held accountable by reason of any disclosure of information as to names and addresses of Holders made pursuant to the Trust Indenture Act. 
  

SECTION 13.3 No Recourse Against Others. 
  
 An incorporator or any past, present or future director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities or this Indenture or for any
claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Holder shall waive and release all such liability. Such waiver and release shall be part of the consideration for the issue of the
Securities. 
  
 SECTION 13.4 Reports by Trustee. 
  
 (a) After this Indenture has been qualified under the Trust Indenture Act, the Trustee shall transmit to Holders such reports concerning the Trustee and its actions under
this Indenture as may be required pursuant to the Trust Indenture Act at the times and in the manner provided therein. If required by Section 313(a) of the Trust Indenture Act, the Trustee shall, within

provided, however, that any such information, documents or reports required to be filed with the Commission pursuant to Section 13 or 15(d) of the Exchange Act shall be filed with the Trustee within 15 days after the same is so required to be filed
with the Commission. 
  
 Delivery of such reports, information and documents to the Trustee is for informational
purposes only and the Trustee’s receipt thereof shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants
hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

 Cell Therapeutics, Inc., a corporation duly organized and existing under the laws of the State of Washington (herein called the “Company,” which term includes any
successor Person under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of

amount may from time to time be increased or decreased to such other principal amounts (which, taken together with the principal amounts of all other Outstanding Securities, shall not exceed $102,900,000 in the aggregate at any time) by adjustments
made on the records of the Trustee hereinafter referred to in accordance with the Indenture)] on June 15, 2008, unless redeemed or repurchased on an earlier date, and to pay interest thereon, from
            , or from the most recent Interest Payment Date (as defined below) to which interest has been paid or duly provided for, semiannually in arrears on June 15 and December 15 in
each year (each, an “Interest Payment Date”), commencing June 15, 2003, at the rate of 5.75% per annum, until the principal hereof is due, and at the rate then in effect on any overdue principal and premium, if any, and, to the extent
permitted by law, on any overdue interest. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the June 1 and December 1 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date.
Except as otherwise provided in the Indenture, any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this
Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Company, notice whereof shall be given to Holders of Registered Securities
not less than ten days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in the Indenture. Payments of principal shall be made upon the surrender of this Security at the option of the Holder at the Corporate Trust Office or at such other office or agency of the
Company as may be designated by it for such purpose in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private
debts, or at such other offices or agencies as the Company may designate, by United States Dollar check drawn on, or wire transfer to, a United States Dollar account (such a wire transfer to be made only to a Holder of an aggregate principal amount
of Registered Securities in excess of U.S.$2,000,000 and only if such Holder shall have furnished wire instructions in writing to the Trustee no later than 15 days prior to the relevant payment date) maintained by the payee. Payment of interest on
this

 Security may be made by United States Dollar check mailed to the address of the Person entitled thereto as such address shall appear in the
Security Register or, upon written application by the Holder to the Security Registrar setting forth wire instructions not later than the relevant Record Date, by wire transfer to a United States dollar account (such a wire transfer to be made only
to a Holder of an aggregate principal amount of Registered Securities in excess of U.S.$2,000,000 and only if such Holder shall have furnished wire instructions in writing to the Trustee no later than 15 days prior to the relevant payment date)

 [FORM OF REVERSE] 
  
 This Security is one of a duly authorized issue of securities of the Company designated as its “5.75% Convertible Senior Subordinated Notes due June 15, 2008”
(herein called the “Securities”), limited in aggregate principal amount to U.S.$102,900,000, issued and to be issued under an Indenture, dated as of [            ], 2002 (herein
called the “Indenture”), between the Company and State Street Bank and Trust Company of California, N.A., a national banking association, as Trustee (herein called the “Trustee,” which term includes any successor trustee under
the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, the holders of Senior
Debt and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. As provided in the Indenture and subject to certain limitations set forth therein, Registered Securities are
exchangeable for a like aggregate principal amount of Registered Securities of any authorized denominations as requested by the Holder surrendering the same upon surrender of the Registered Security or Registered Securities to be exchanged at the
Corporate Trust Office. The Trustee upon such surrender by the Holder will issue the new Registered Securities in the requested denominations. 
  
 No sinking fund is provided for the Securities. 
  
 The Securities
are subject to redemption at the option of the Company at any time on or after June 21, 2004, in whole or in part, upon not less than 30 nor more than 60 days’ notice to the Holders prior to the Redemption Date at the following Redemption
Prices (expressed as percentages of the principal amount) for the twelve-month period beginning on June 15 of the following years (June 21 through June 14 in the case of the first of such periods): 
  
 
	 Year
 
	  	 Redemption Price

	 2006
 	  	 101.643
 	 %
 
	 2007
 	  	 100.821
 	 %
 

 
  
 and thereafter at a Redemption Price equal to 100% of the principal amount, together, in
each case, with accrued interest to, but excluding the Redemption Date; provided, however, that interest installments on Securities whose Stated Maturity is on or prior to such Redemption Date will be payable to the Holders of such Securities, or
one or more Predecessor Securities, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Indenture. 
  
 The Securities are subject to redemption at the option of the Company at any time before June 21, 2004 (“Provisional Redemption”), in whole or in part, upon not
less than 30 nor more than 60 days’ notice to the Holders prior to the Redemption Date at a Redemption Price equal to 100% of the principal amount, together, in each case, with accrued interest to, but excluding, the Redemption
 

 
 A-5 

 
Date, if the closing price of the Company’s Common Stock has exceeded 150% of the Conversion Price then in effect for at least 20 trading days within a period of 30 consecutive trading days
ending on the trading day before the date of mailing of the notice of the Provisional Redemption. Upon any Provisional Redemption, the Company will pay to the Holders cash or Common Stock, or in a combination of cash and Common Stock, with respect
to the Securities called for Provisional Redemption, and previously converted after the notice of Provisional Redemption and before to the date of the Provisional Redemption, in an amount equal to $86.25 per $1,000 principal amount of the
Securities, less the amount of any interest paid on the Securities before the date of the Provisional Redemption. For purposes of any such payment in Common Stock, the value of such Common Stock will be based upon the highest closing price of shares
of the Common Stock for the 20 trading days referred to above. 
  
 In the event of a redemption of the Securities,
the Company will not be required (a) to register the transfer or exchange of Registered Securities for a period of 15 days immediately preceding the date notice is given identifying the serial numbers of the Securities called for such redemption (it
being understood that the Company will not be required to identify the serial numbers of Outstanding Securities if all such Securities are called for redemption) or (b) to register the transfer or exchange of any Registered Security, or portion
thereof, called for redemption. 
  
 Notice to the Holders will be given not less than 30 nor more than 60 days prior
to the Redemption Date as provided in the Indenture. 
  
 In any case where the due date for the payment of the
principal of, premium, if any, or interest on any Security or the last day on which a Holder of a Security has a right to convert his Security shall be, at any Place of Payment or Place of Conversion, as the case may be, a day on which banking
institutions at such Place of Payment or Place of Conversion are authorized or obligated by law or executive order to close, then payment of principal, premium, if any, or interest or delivery for conversion of such Security need not be made on or
by such date at such place but may be made on or by the next succeeding day at such place which is not a day on which banking institutions are authorized or obligated by law or executive order to close, with the same force and effect as if made on
the date for such payment or the date fixed for redemption or repurchase, or by such last day for conversion, and no interest shall accrue on the amount so payable for the period from and after such due date. 
  
 Subject to and upon compliance with the provisions of the Indenture, the Holder of this Security is entitled, at his option, at any time
following the original issue date of the Securities and on or before the close of business on June 15, 2008, or in case this Security or a portion hereof is called for redemption or the Holder hereof has exercised his right to require the Company to
repurchase this Security or such portion hereof, then in respect of this Security until and including, but (unless the Company defaults in making the payment due upon redemption or repurchase, as the case may be) not after, the close of business on
the Business Day immediately preceding the Redemption Date or the Repurchase Date, as the case may be, to convert this Security or any portion of the principal amount hereof that is an integral multiple of U.S.$1,000 (provided that the unconverted
portion of such principal amount is U.S.$1,000 or any integral multiple of U.S.$1,000
 

 
 A-6 

 
in excess thereof) into fully paid and nonassessable shares of Common Stock of the Company at an initial Conversion Rate of 100.0 (or at the current adjusted Conversion Rate if an adjustment has
been made as provided in the Indenture) by surrender of this Security, duly endorsed or assigned to the Company or in blank and, in case such surrender shall be made 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 (except if this Security has been called for redemption on a Redemption Date or is repurchasable on a Repurchase Date, with the consequence that the
conversion right of such Security would terminate between such Regular Record Date and the close of business on such Interest Payment Date), also accompanied by payment in New York Clearing House or other funds acceptable to the Company of an amount
equal to the interest payable on such Interest Payment Date on the principal amount of this Security then being converted, and also the conversion notice hereon duly executed, to the Company at the Corporate Trust Office, or at such other office or
agency of the Company, subject to any laws or regulations applicable thereto and subject to the right of the Company to terminate the appointment of any Conversion Agent (as defined below) as may be designated by it for such purpose in the Borough
of Manhattan, The City of New York, or at such other offices or agencies as the Company may designate (each a “Conversion Agent”), provided, further, that in case surrender of this Security for conversion shall be made 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 and if this Security or portion hereof has been called for redemption on a Redemption Date or is
repurchasable on a Repurchase Date, with the consequence that the conversion right of such Security would terminate between such Regular Record Date and the close of business on such Interest Payment Date, then the Holder of this Security will be
entitled to receive the interest accruing hereon from the Interest Payment Date next preceding the date of such conversion to such succeeding Interest Payment Date and shall not be required to pay such interest upon surrender of this Security for
conversion. Subject to the provisions of the preceding sentence and, in the case of a conversion after the close of business on the Regular Record Date next preceding any Interest Payment Date and on or before the close of business on such Interest
Payment Date, to the right of the Holder of this Security (or any Predecessor Security of record as of such Regular Record Date) to receive the related installment of interest to the extent and under the circumstances provided in the Indenture, no
cash payment or adjustment is to be made on conversion for interest accrued hereon from the Interest Payment Date next preceding the day of conversion, or for dividends on the Common Stock issued on conversion hereof. The Company shall thereafter
deliver to the Holder the fixed number of shares of Common Stock (together with any cash adjustment or rights or warrants, as provided in the Indenture) into which this Security is convertible and such delivery will be deemed to satisfy the
Company’s obligation to pay the principal amount of this Security. No fractions of shares or scrip representing fractions of shares will be issued on conversion, but instead of any fractional interest (calculated to the nearest 1/100th of a
share) the Company shall pay a cash adjustment as provided in the Indenture. The Conversion Rate 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 conveyance, transfer, sale or lease of all or substantially all of the property and 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, 
  

 
 A-7 

 
cash and other property receivable upon such consolidation, merger, conveyance, transfer, sale or lease by a holder of the number of shares of Common Stock of the Company into which this Security
could have been converted immediately prior to such consolidation, merger, conveyance, transfer, sale or lease (assuming such holder of Common Stock is not a Constituent Person, 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). No adjustment in the Conversion Rate will be made until such adjustment would require an increase or decrease of at least one percent of such rate, provided that any
adjustment that would otherwise be made will be carried forward and taken into account in the computation of any subsequent adjustment. 
  
 Subject to certain limitations in the Indenture, at any time when the Company is not subject to Section 13 or 15(d) of the United States Securities Exchange Act of 1934, as amended, upon the request of a Holder of a Security
or the holder of shares of Common Stock issued upon conversion thereof, the Company will promptly furnish or cause to be furnished Rule 144A Information (as defined below) to such Holder of Securities or such holder of shares of Common Stock issued
upon conversion of Securities, or to a prospective purchaser of any such security designated by any such Holder or holder, as the case may be, to the extent required to permit compliance by such Holder or holder with Rule 144A under the Securities
Act of 1933, as amended (the “Securities Act”), in connection with the resale of any such security. “Rule 144A Information” shall be such information as is specified pursuant to Rule 144A(d)(4) under the Securities Act (or any
successor provision thereto). 
  
 If a Change in Control occurs, the Holder of this Security, at the Holder’s
option, shall have the right, in accordance with the provisions of the Indenture, to require the Company to repurchase this Security (or any portion of the principal amount hereof that is equal to U.S.$1,000 or any greater integral multiple of
U.S.$1,000) for cash at a Repurchase Price equal to 100% of the principal amount thereof plus interest accrued to, but excluding, the Repurchase Date. At the option of the Company, the Repurchase Price may be paid in cash or, subject to the
conditions provided in the Indenture, by delivery of shares of Common Stock or in a combination of cash and Common Stock, having a fair market value equal to the Repurchase Price. For purposes of this paragraph, the fair market value of shares of
Common Stock shall be determined by the Company and shall be equal to 95% of the average of the closing price per share for the five consecutive Trading Days immediately preceding and including the third Trading Day prior to the Repurchase Date.
Whenever in this Security there is a reference, in any context, to the principal of any Security as of any time, such reference shall be deemed to include reference to the Repurchase Price payable in respect of such Security to the extent that such
Repurchase Price is, was or would be so payable at such time, and express mention of the Repurchase Price in any provision of this Security shall not be construed as excluding the Repurchase Price so payable in those provisions of this Security when
such express mention is not made; provided, however, that, for the purposes of the paragraph below concerning the consequences of an Event of Default, such reference shall be deemed to include reference to the Repurchase Price only to the extent the
Repurchase Price is payable in cash. 
  
 [The following paragraph shall appear in each Registered Security that is
not a Global Security: 
  

 
 A-8 

  
 In the event of redemption, repurchase or conversion of this Security in part
only, a new Registered Security or Registered Securities for the unredeemed, unrepurchased or unconverted portion hereof will be issued in the name of the Holder hereof.] 
  
 [The following paragraph shall appear in each Global Security: 
  
 In
the event of a deposit or withdrawal of an interest in this Security, including an exchange, transfer, redemption, repurchase or conversion of this Security in part only, the Trustee, as custodian of the Depositary, shall make an adjustment on its
records to reflect such deposit or withdrawal in accordance with the Applicable Procedures.] 
  
 The indebtedness
evidenced by this Security is, to the extent and in the manner provided in the Indenture, subordinate and subject in right of payment to the prior payment in full in cash or Cash Equivalents of all Senior Debt of the Company, and this Security is
issued subject to such provisions of the Indenture with respect thereto. Each Holder of this Security, by accepting the same, 
  
 (a) agrees to and shall be bound by such provisions, 
  
 (b) authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination so provided and 
  
 (c) appoints the Trustee his attorney-in-fact for any and all such purposes. 
  
 If an Event of Default shall occur and be continuing, the principal of all the Securities, together with accrued interest to the date of declaration, may be declared due
and payable in the manner and with the effect provided in the Indenture. Upon payment (i) of the amount of principal so declared due and payable, together with accrued interest to the date of declaration, and (ii) of interest on any overdue
principal and, to the extent permitted by applicable law, overdue interest, all of the Company’s obligations in respect of the payment of the principal of and interest on the Securities shall terminate. 
  
 The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders of the Securities under the Indenture at any time by the Company and the Trustee with the written consent of the Holders of a majority in principal amount of the Securities at the time
Outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of
this Security and of any Security issued in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security or such other Security. 
  
 As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the
Indenture or for the
 

 
 A-9 

 
appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default, the Holders of
not less than 25% in principal amount of the Outstanding Securities shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, the Trustee
shall have failed to institute any such proceeding for 60 days after receipt of such notice, request and offer of indemnity, and the Trustee has not received any direction inconsistent with such written request from the Holders of a majority of the
aggregate principal amount of the Outstanding Securities during such 60 day period. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof, premium, if any, or
interest hereon on or after the respective due dates expressed herein or for the enforcement of the right to convert this Security as provided in the Indenture. 
  
 No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal
of, premium, if any, and interest on this Security at the times, places and rate, and in the coin or currency, herein prescribed or to convert this Security as provided in the Indenture. 
  
 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of Registered Securities is registrable on the Security Register upon
surrender of a Registered Security for registration of transfer at the Corporate Trust Office of the Trustee or at such other office or agency of the Company as may be designated by it for such purpose in the Borough of Manhattan, The City of New
York, or at such other offices or agencies as the Company may designate, duly endorsed by, or 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, and thereupon one or more new Registered Securities, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees by the Registrar. No
service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to recover any tax or other governmental charge payable in connection therewith. 
  
 Prior to due presentation of a Registered 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 Registered Security is registered as the owner thereof for all purposes, whether or not such Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice
to the contrary. 
  
 Interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day
months. The Indenture and this Security shall be governed by and construed in accordance with the laws of the State of New York, United States of America, including, without limitation, Section 5-1401 of the New York General Obligations Law.

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