or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the outstanding Securities shall be computed as of such record date; provided that no such authorization,
agreement or consent by the Holders of the Securities on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date.

the date of authentication of such Securities. 
  
 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 duly 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. 
  
 The Trustee shall authenticate and deliver the Securities for original issue
in an aggregate principal amount of up to $200,000,000 Debentures upon one or more Company Orders without any further action by the Company (other than as contemplated in Section 13.04 and Section 13.05 hereof). 
  
 Notwithstanding anything herein to the contrary, the Company may without the
consent of the Holders, issue additional Securities under the Indenture of the same tenor and with the same CUSIP numbers as other Securities in an unlimited aggregate principal amount; provided that no such additional Securities may be

of $1,000.

 The Company shall enter into an appropriate agency agreement with any

Company shall notify the Trustee of the name and address of any such agent. If the Company fails to maintain a Registrar, Paying Agent or Conversion Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor
pursuant to Section 8.07. The Company or any Subsidiary or an Affiliate of either of them may act as Paying Agent, Registrar, Conversion Agent or co-registrar. 
  
 The Company initially appoints the Trustee as Registrar, Conversion Agent and Paying Agent in connection with the
Securities. 
  
 Section 2.04. Paying Agent to Hold Money
and Securities in Trust. Except as otherwise provided herein, on or prior to each due date of payments in respect of any Security, the Company shall deposit with the Paying Agent a sum of money (in immediately available funds if deposited on the

Securityholders or the Trustee all money and shares of Common Stock held by the Paying Agent for the making of payments in respect of the Securities and shall notify the Trustee of any default by the Company in making any such payment. At any time
during the continuance of any such default, the Paying Agent shall, upon the written request of the Trustee, forthwith pay to the Trustee all money and shares of Common Stock so held in trust. If the Company, a Subsidiary or an Affiliate of either
of them acts as Paying Agent, it shall segregate the money and shares of Common Stock held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money and shares of Common Stock
held by it to the Trustee and to account for any funds and Common Stock disbursed by it. Upon doing so, the Paying Agent shall have no further liability for the money or shares of Common Stock. 
  
 Section 2.05. Securityholder Lists. The Trustee shall preserve

Securityholders dated within 15 days of the date on which the list is furnished and at such other times as the Trustee may request in writing a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of
Securityholders.

 Section 2.06. Transfer and Exchange.  
  
 (a) Subject to Section 2.12 hereof, upon surrender for registration of
transfer of any Security, together with a written instrument of transfer satisfactory to the Registrar duly executed by the Securityholder or such Securityholder’s attorney duly authorized in writing, at the office or agency of the Company
designated as Registrar or co-registrar pursuant to Section 2.03, 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
denomination or denominations, of a like aggregate principal amount. The Company shall not charge a service charge for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to pay all taxes, assessments or
other governmental charges that may be imposed in connection with the transfer or exchange of the Securities from the Securityholder requesting such transfer or exchange. 
  
 At the option of the Holder, Securities may be exchanged for other Securities of any authorized denomination or
denominations, of a like aggregate principal amount upon surrender of the Securities to be exchanged, together with a written instrument of transfer satisfactory to the Registrar duly executed by the Securityholder or such Securityholder’s
attorney duly authorized in writing, at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive. 
  
 The Company shall not be required to
make, and the Registrar need not register, transfers or exchanges of Securities selected for redemption (except, in the case of Securities to be redeemed in part, the portion thereof not to be redeemed) or any Securities in respect of which a
Repurchase Notice or Designated Event Repurchase Notice has been given and not withdrawn by the Holder thereof in accordance with the terms of this Indenture (except, in the case of Securities to be purchased in part, the portion thereof not to be
purchased) or any Securities for a period of 15 days before the mailing of a notice of redemption of Securities to be redeemed. 
  
 (b) Notwithstanding any provision to the contrary herein, so long as a Global Security remains outstanding and is held by or on behalf of the Depositary,
transfers of a Global Security, in whole or in part, shall be made only in accordance with Section 2.12 and this Section 2.06(b). Transfers of a Global Security shall be limited to transfers of such Global Security in whole or in part, to
the Depositary, to nominees of the Depositary or to a successor of the Depositary or such successor’s nominee. 
  
 (c) Successive registrations and registrations of transfers and exchanges as aforesaid may be made from time to time as desired, and each such
registration shall be noted on the register for the Securities. 
  

 17 








 (d) Any Registrar appointed pursuant to Section 2.03 hereof shall provide to the Trustee such
information as the Trustee may reasonably require in connection with the delivery by such Registrar of Securities upon transfer or exchange of Securities. 
  
 (e) No Registrar shall be required to make registrations of transfer or exchange of Securities during any periods designated in the text of the Securities
or in this Indenture as periods during which such registration of transfers and exchanges need not be made. 
  
 (f) If Securities are issued upon the transfer, exchange or replacement of Securities subject to restrictions on transfer and bearing the legends set
forth on the forms of Security attached hereto as Exhibits A and B setting forth such restrictions (collectively, the “Legend”), or if a request is made to remove the Legend on a Security, the Securities so issued shall bear the
Legend, or the Legend shall not be removed, as the case may be, unless there is delivered to each of the Company and the Trustee, and the Registrar (if not the same Person as the Trustee) such satisfactory evidence, which shall include an opinion of
counsel, as may be reasonably required by the Company and the Trustee (if not the same Person as the Trustee), that neither the Legend nor the restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the
provisions of Rule 144A or Rule 144 under the Securities Act or that such Securities are not “restricted” within the meaning of Rule 144 under the Securities Act. Upon (i) provision of such satisfactory evidence, or
(ii) notification by the Company to the Trustee and Registrar of the sale of such Security pursuant to a registration statement that is effective at the time of such sale, the Trustee, at the written direction of the Company, shall authenticate
and deliver a Security that does not bear the Legend. If the Legend is removed from the face of a Security and the Security is subsequently held by the Company or an Affiliate of the Company, the Legend shall be reinstated. 
  
 Section 2.07. Replacement Securities. If (a) any mutilated
Security is surrendered to the Trustee, or (b) the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company and the Trustee such security or
indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and upon its written request
the Trustee shall authenticate and deliver, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount, bearing a certificate number not contemporaneously
outstanding. 
  
 In case any such mutilated, destroyed, lost or
stolen Security has become or is about to become due and payable, or is about to be purchased by the Company pursuant to Article 3 hereof, the Company in its discretion may, instead of issuing a new Security, pay or purchase such Security, as the
case may be. 
  

 18 








 Upon the issuance of any new Securities under this Section 2.07, the Company may require the payment
of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 
  
 Every new Security issued pursuant to this Section 2.07 in lieu of any
mutilated, destroyed, lost or stolen Security shall constitute an original contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits
of this Indenture equally and proportionately with any and all other Securities duly issued hereunder. 
  
 The provisions of this Section 2.07 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities. 
  
 Section 2.08. Outstanding Securities; Determinations of Holders’ Action. Securities outstanding at any time are all the Securities authenticated by the Trustee except for those cancelled by it, those
paid pursuant to Section 2.07, those delivered to it for cancellation and those described in this Section 2.08 as not outstanding. A Security does not cease to be outstanding because the Company or an Affiliate thereof holds the Security;
provided, however, that in determining whether the Holders of the requisite principal amount of Securities have given or concurred in any request, demand, authorization, direction, notice, consent, waiver, or other Act hereunder, Securities
owned by the Company or any other obligor upon the Securities or any Affiliate of the Company or such other obligor shall be disregarded and deemed not to be outstanding, except that, in determining whether the Trustee shall be protected in relying
upon any such request, demand, authorization, direction, notice, consent, waiver or other act, only Securities which a Responsible Officer of the Trustee actually knows to be so owned shall be so disregarded. Subject to the foregoing, only
Securities outstanding at the time of such determination shall be considered in any such determination (including, without limitation, determinations pursuant to Articles 7 and 10). 
  
 If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof
satisfactory to it that the replaced Security is held by a bona fide purchaser. 
  
 If the Paying Agent holds, in accordance with this Indenture, on a Redemption Date, or on the Business Day immediately following a Repurchase Date or a Designated Event Repurchase Date, or on Stated Maturity, money or
securities, if permitted hereunder, sufficient to pay Securities payable on that date, then immediately after such Redemption Date, Repurchase Date, Designated Event Repurchase Date or Stated Maturity, as the case may be, such Securities shall cease
to be outstanding and Interest and Additional Interest, if any, on such Securities shall cease to accrue; provided, that if such Securities are to be redeemed, notice of such redemption has been duly given pursuant to this Indenture or
provision therefor satisfactory to the Trustee has been made. 
  

 19 








 If a Security is converted in accordance with Article 11, then from and after the time of conversion on
the date of conversion, such Security shall cease to be outstanding and Interest and Additional Interest, if any, shall cease to accrue on such Security. 
  
 Section 2.09. Temporary Securities. Pending the preparation of definitive Securities, the Company may execute, and upon Company Order the
Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which
they are issued and with such appropriate insertions, omissions, substitutions and other variations as the Officers executing such Securities may determine, as conclusively evidenced by their execution of such Securities. 
  
 If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary Securities shall be exchangeable for definitive Securities upon surrender of the temporary Securities at the office or agency of the
Company designated for such purpose pursuant to Section 2.03, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities the Company shall execute and the Trustee shall authenticate and deliver in
exchange therefor a like principal amount of definitive Securities of authorized denominations. Until so exchanged the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities.

  
 Section 2.10. Cancellation. All Securities
surrendered for payment, purchase by the Company pursuant to Article 3, conversion, redemption or registration of transfer or exchange shall, if surrendered to any person other than the Trustee, the Registrar or the Paying Agent, as the case may be,
be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner
whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. The Company may not issue new Securities to replace Securities it has paid or delivered to the Trustee for cancellation (other than in connection with
registrations of transfer or exchange) or that any Holder has converted pursuant to Article 11. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by
this Indenture. All cancelled Securities held by the Trustee shall be disposed of by the Trustee in accordance with the Trustee’s customary procedure. 
  
 Section 2.11. Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any
agent of 
  

 20 








 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 the principal amount of the Security or any portion thereof, or the payment of any Redemption Price, Repurchase Price or Designated Event Repurchase Price in respect thereof, and Interest or Additional
Interest thereon, for the purpose of conversion 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 2.12. Global Securities. 

  
 (a) Notwithstanding any other provisions of this Indenture or
the Securities, (A) transfers of a Global Security, in whole or in part, shall be made only in accordance with Section 2.06 and Section 2.12(a)(i), (B) transfers of a beneficial interest in a Global Security for a Certificated
Security shall comply with Section 2.06, Section 2.12(a)(ii) and Section 2.12(e)(i), and (C) transfers of a Certificated Security shall comply with Section 2.06, Section 2.12(a)(iii) and Section 2.12(a)(iv).

  
 (i) Transfer of Global Security. A
Global Security may not be transferred, in whole or in part, to any Person other than the Depositary or a nominee or any successor thereof, and no such transfer to any such other Person may be registered; provided that this clause shall not
prohibit any transfer of a Security that is issued in exchange for a Global Security but is not itself a Global Security. No transfer of a Security to any Person shall be effective under this Indenture or the Securities unless and until such
Security has been registered in the name of such Person. Nothing in this Section 2.12(a)(i) shall prohibit or render ineffective any transfer of a beneficial interest in a Global Security effected in accordance with the other provisions of this
Section 2.12(a). 
  
 (ii) Restrictions on
Transfer of a Beneficial Interest in a Global Security for a Certificated Security. A beneficial interest in a Global Security may not be exchanged for a Certificated Security except upon satisfaction of the requirements set forth below and in
Section 2.12(e)(i) below. Upon receipt by the Trustee of a transfer of a beneficial interest in a Global Security in accordance with Applicable Procedures for a Certificated Security in the form satisfactory to the Trustee, together with:

  
 (A) so long as the Securities are Restricted
Securities, certification in the form set forth in Exhibit C; 
  
 (B) written instructions to the Trustee to make, or direct the Registrar to make, an adjustment on its books and records with respect to such Global Security to reflect a decrease in the aggregate principal amount of
the Securities represented by the Global Security, such instructions to contain information regarding the Depositary account to be credited with such decrease; and 
  

 21 








 (C) if the Company or the Trustee so requests, an opinion of counsel or other evidence
reasonably satisfactory to it as to the compliance with the restrictions set forth in the Legend, 
  
 then the Trustee shall cause, or direct the Registrar to cause, in accordance with the standing instructions and procedures existing between the
Depositary and the Registrar, the aggregate principal amount of the Securities represented by the Global Security to be decreased by the aggregate principal amount of the Certificated Security to be issued, shall issue such Certificated Security and
shall debit or cause to be debited to the account of the person specified in such instructions a beneficial interest in the Global Security equal to the principal amount of the Certificated Security so issued. 
  
 (iii) Transfer and Exchange of Certificated
Securities. When Certificated Securities are presented to the Registrar with a request: 
  
 (y) to register the transfer of such Certificated Securities; or 
  
 (z) to exchange such Certificated Securities for an equal principal amount of Certificated Securities of
other authorized denominations, 
  
 the Registrar shall register
the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided, however, that the Certificated Securities surrendered for transfer or exchange: 
  
 (A) shall be duly endorsed or accompanied by a written
instrument of transfer in form reasonably satisfactory to the Company and the Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing; and 
  
 (B) so long as such Securities are Restricted Securities, such Securities are being transferred or exchanged
pursuant to an effective registration statement under the Securities Act or pursuant to clause (1), (2) or (3) below, and are accompanied by the following additional information and documents, as applicable: 
  
 (1) if such Certificated Securities are being delivered to
the Registrar by a Holder for registration in the name of such Holder, without transfer, a certification from such Holder to that effect; or 
  

 22 








 (2) if such Certificated Securities are being transferred to the Company, a
certification to that effect; or 
  
 (3) if such
Certificated Securities are being transferred pursuant to an exemption from registration, (i) a certification to that effect (in the form set forth in Exhibit C, if applicable) and (ii) if the Company or the Trustee so requests, an opinion
of counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the Legend. 
  
 (iv) Restrictions on Transfer of a Certificated Security for a Beneficial Interest in a Global Security. A Certificated Security
may not be exchanged for a beneficial interest in a Global Security except upon satisfaction of the requirements set forth below. 
  
 Upon receipt by the Trustee of a Certificated Security, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the
Trustee, together with: 
  
 (A) so long as the
Securities are Restricted Securities, certification, in the form set forth in Exhibit C, that such Certificated Security (1) is being transferred to a QIB in accordance with Rule 144A under the Securities Act or (2) is being transferred
pursuant to and in compliance with Rule 144 under the Securities Act; and 
  
 (B) written instructions directing the Trustee to make, or to direct the Registrar to make, an adjustment on its books and records with respect to such Global Security to reflect an increase in the aggregate principal
amount of the Securities represented by the Global Security, such instructions to contain information regarding the Depositary account to be credited with such increase, then the Trustee shall cancel such Certificated Security and cause, or direct
the Registrar to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Registrar, the aggregate principal amount of Securities represented by the Global Security to be increased by the aggregate
principal amount of the Certificated Security to be exchanged, and shall credit or cause to be credited to the account of the person specified in such instructions a beneficial interest in the Global Security equal to the principal amount of the
Certificated Security so cancelled. If no Global Securities are then outstanding, the Company shall issue and the Trustee shall authenticate, upon written order of the Company in the form of an Officers’ Certificate, a new Global Security in
the appropriate principal amount. 
  

 23 








 (b) Subject to Section 2.12(c), every Security shall be subject to the restrictions on transfer
provided in the Legend including the delivery of an opinion of counsel, if so provided. Whenever any Restricted Security is presented or surrendered for registration of transfer or for exchange for a Security registered in a name other than that of
the Holder, such Security must be accompanied by a certificate in substantially the form set forth in Exhibit C, dated the date of such surrender and signed by the Holder of such Security, as to compliance with such restrictions on transfer. The
Registrar shall not be required to accept for such registration of transfer or exchange any Security not so accompanied by a properly completed certificate. 
  
 (c) The restrictions imposed by the Legend upon the transferability of any Security shall cease and terminate when such Security has been sold pursuant to
an effective registration statement under the Securities Act or transferred in compliance with Rule 144 under the Securities Act (or any successor provision thereto) or, if earlier, upon the expiration of the holding period applicable to sales
thereof under Rule 144(k) under the Securities Act (or any successor provision). Any Security as to which such restrictions on transfer shall have expired in accordance with their terms or shall have terminated may, upon a surrender of such Security
for exchange to the Registrar in accordance with the provisions of this Section 2.12 (accompanied, in the event that such restrictions on transfer have terminated by reason of a transfer in compliance with Rule 144 or any successor provision,
by an opinion of counsel having substantial experience in practice under the Securities Act and otherwise reasonably acceptable to the Company and the Trustee, addressed to the Company and the Trustee and in form acceptable to the Company and the
Trustee, to the effect that the transfer of such Security has been made in compliance with Rule 144 or such successor provision), be exchanged for a new Security, of like tenor and aggregate principal amount, which shall not bear the restrictive
Legend. The Company shall inform the Trustee of the effective date of any registration statement registering the Securities under the Securities Act. The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith in
accordance with the aforementioned opinion of counsel or registration statement. 
  
 (d) As used in the preceding two paragraphs of this Section 2.12, the term “transfer” encompasses any sale, pledge, transfer, loan, hypothecation, or other disposition of any Security.

  
 (e) The provisions of clauses (i), (ii), (iii), (iv) and
(v) of this Section 2.12(e) shall apply only to Global Securities: 
  
 (i) Notwithstanding any other provisions of this Indenture or the Securities, a Global Security shall not be exchanged in whole or in part for a Security registered in the name of any Person other than the 

 

 24 








 Depositary or one or more nominees thereof, provided that a Global Security may be exchanged for
Securities registered in the names of any person designated by the Depositary in the event that (A) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security, and a successor
Depositary is not appointed by the Company within 90 days, (B) at any time, the Company, in its sole discretion, but to the extent permitted by the Depositary, determines not to have Securities represented by Global Securities, or (C) upon
a request by or on behalf of the Depositary following the request of any beneficial owner seeking to exercise or enforce its rights under the Securities, a beneficial interest in a Global Security may be exchanged for a security in registered form
in accordance with the Depositary’s procedures. Any Global Security exchanged pursuant to clause (A) above shall be so exchanged in whole and not in part, and any Global Security exchanged pursuant to clause (B) above may be exchanged
in whole or from time to time in part as directed by the Depositary. Any Security issued in exchange for a Global Security or any portion thereof shall be a Global Security; provided that any such Security so issued that is registered in the
name of a person other than the Depositary or a nominee thereof shall not be a Global Security. 
  
 (ii) Securities issued in exchange for a Global Security or any portion thereof shall be issued in definitive, fully registered form,
shall have an aggregate principal amount equal to that of such Global Security or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear the
applicable legends provided for herein. Any Global Security to be exchanged in whole shall be surrendered by the Depositary to the Registrar. With regard to any Global Security to be exchanged in part, either such Global Security shall be so
surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with respect to such Global Security, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged,
by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Security issuable on such exchange to or upon the order of the Depositary or an
authorized representative thereof. 
  
 (iii)
Subject to the provisions of clause (v) of this Section 2.12(e), the registered Holder may grant proxies and otherwise authorize any person, including Agent Members (as defined below) and persons that may hold interests through Agent
Members, to take any action which a holder is entitled to take under this Indenture or the Securities. 
  
 (iv) In the event of the occurrence of any of the events specified in clause (i) of this Section 2.12(e), the Company will
promptly notify the Trustee and make available to the Trustee a reasonable supply of Certificated Securities in definitive, fully registered form. 
  

 25 








 (v) Neither any members of, or participants in, the Depositary (collectively, the
“Agent Members”) nor any other persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Security registered in the name of the Depositary or any nominee thereof, or under
any such Global Security, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and holder of such Global Security for all purposes
whatsoever; provided that an owner of a beneficial interest in a Global Security may directly enforce against the Company, without any proxy, comment, solicitation, waiver or any participation of the Depositary, its right to exchange such
beneficial interest for a Security in registered form pursuant to Section 2.12(e)(i) above. Notwithstanding the foregoing, nothing herein shall (A) prevent the Company, the Trustee or any agent of the Company or the Trustee from giving
effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or (B) impair, as between the Depositary, its Agent Members and any other person on whose behalf an Agent Member
may act, the operation of customary practices of such Persons governing the exercise of the rights of a holder of any Security. 
  
 Subject to the right of a beneficial owner to receive certificated Securities pursuant to Section 2.12(e)(i)(C), none of the Trustee,
any Paying Agent, Conversion Agent or the Registrar shall have any responsibility or obligation to any beneficial owner of a Global Security, a member of, or a participant in the Depository or other Person with respect to the accuracy of the records
of the Depository or its nominee or of any participant or member thereof, with respect to any ownership interest in the Securities or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the
Depository) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Securities. All notices and communications to be given to the Holders and all payments to be made to Holders under the
Securities shall be given or made only to or upon the order of the registered Holders (which shall be the Depository or its nominee in the case of the Global Securities). The rights of beneficial owners of any Global Security shall be exercised only
through the Depository subject to the applicable rules and procedures of the Depository. The Trustee, any Paying Agent, the Conversion Agent and the Registrar may rely and shall be fully protected in relying upon information furnished by the
Depository with respect to its members, participants and any beneficial owners. The Trustee, each Paying Agent, the Conversion Agent and the Registrar shall be entitled to deal with any depositary (including the Depository), and any 
  

 26 








 nominee thereof, that is the Holder of any Global Security for all purposes of this Indenture relating to
such Global Security (including the payment of principal, premium, if any, and interest and additional amounts, if any, and the giving of instructions or directions by or to the owner or holder of a beneficial ownership interest in such Global
Security) as the sole Holder of such Global Security and shall have no obligations to the beneficial owners thereof. None of the Trustee, any Paying Agent, the Conversion Agent or the Registrar shall have any responsibility or liability for any acts
or omissions of any such depositary with respect to any Global Security, for the records of any such depositary, including records in respect of beneficial ownership interests in respect of any such Global Security, for any transactions between such
depositary and any participant in such depositary or between or among any such depositary, any such participant and/or any holder or owner of a beneficial interest in such Global Security or for any transfers of beneficial interests in any such
Global Security. 
  
 (f) The Trustee shall have no obligation or
duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among
Depository participants, members or beneficial owners of any Global Security) other than to make any required delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required
by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. 
  
 Section 2.13. CUSIP, ISIN or Other Similar Numbers. The Company may issue the Securities with one or more “CUSIP,” ISIN or other
similar numbers (if then generally in use), and, if so, the Trustee shall use such “CUSIP,” ISIN or other similar numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no
representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and
any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the CUSIP, ISIN or other similar numbers.

 ARTICLE 3 
 REDEMPTION AND REPURCHASES 
  
 Section 3.01. Company’s Right to Redeem; Notices to Trustee. Prior to April 15, 2009, the Debentures will not be redeemable at the
Company’s option. Beginning on April 15, 2009, the Company, at its option, may redeem the Debentures, for cash at any time as a whole, or from time to time in part, at a redemption price (the “Redemption Price”) equal to
100% of the principal amount of the Securities redeemed plus accrued and unpaid Interest and accrued and unpaid Additional Interest, if any, on the Securities redeemed to (but excluding) the Redemption Date; provided that if the Redemption
Date falls after an Interest Record Date and on or prior to the related Interest Payment Date, the Redemption Price shall only be 100% of the principal amount of Securities to be redeemed and the Company shall pay such accrued and unpaid Interest on
such Interest Payment Date to the Holder of the Securities on such Interest Record Date. If the Company elects to redeem Securities, it shall notify the Trustee in writing of the Securities being redeemed, the Redemption Date, the applicable
Conversion Rate, the principal amount of Securities to be redeemed and the Redemption Price. 
  
 The Company shall give the notice to the Trustee provided for in this Section 3.01 by a Company Order, at least 30 days but not more than 60 days before the Redemption Date (unless a shorter notice shall be
satisfactory to the Trustee). 
  
 Securities called for redemption
may be converted at any time prior to the close of business on the Business Day immediately preceding the Redemption Date. 
  
 Section 3.02. Selection of Securities to be Redeemed. If less than all of the Securities are to be redeemed, unless the procedures of the
Depositary provide otherwise, the Trustee shall select the Securities to be redeemed by lot, on a pro rata basis or by another method the Trustee considers fair and appropriate (so long as such method is not prohibited by the rules of any stock
exchange on which the Securities are then listed). Subject to the previous sentence, the Trustee shall make the selection within five Business Days after it receives the notice provided for in Section 3.01 from outstanding Securities not
previously called for redemption. The Trustee may select for redemption portions of the principal amount of Securities that have denominations larger than $1,000. 
  
 Securities and portions of Securities that the Trustee selects shall be in principal amounts of $1,000 or an integral
multiple of $1,000. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company promptly of the Securities or portions of the Securities
to be redeemed. 
  

 28 








 If any Security selected for partial redemption is converted in part, 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. 
  
 Section 3.03. Notice of Redemption. At
least 30 days but not more than 60 days before a Redemption Date, the Company shall mail a notice of redemption by first-class mail, postage prepaid, to each Holder of Securities to be redeemed. 
  
 The notice shall identify the Securities to be redeemed and shall state:

  
 (a) the Securities being redeemed;

  
 (b) the Redemption Date; 
  
 (c) the Redemption Price; 
  
 (d) the Conversion Rate; 
  
 (e) the name and address of the Paying Agent and the
Conversion Agent; 
  
 (f) that Securities called
for redemption may be converted at any time before the close of business on the Business Day prior to the Redemption Date; 
  
 (g) that Securities called for redemption and not converted will be redeemed on the Redemption Date; 
  
 (h) that Holders who want to convert their Securities must
satisfy the requirements set forth in the Securities; 
  
 (i) that Securities called for redemption must be surrendered to the Paying Agent to collect the Redemption Price; 
  
 (j) if fewer than all of the outstanding Securities are to be redeemed, the certificate numbers, if any, and principal amounts of the
particular Securities to be redeemed; 
  
 (k)
that, unless the Company defaults in making payment of such Redemption Price, Interest and Additional Interest, if any, on Securities called for redemption will cease to accrue on and after the Redemption Date; and 
  
 (l) the CUSIP, ISIN or other similar number(s), as the case
may be, of the Securities being redeemed. 
  

 29 








 At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name
and at the Company’s expense, provided that the Company makes such request at least seven Business Days prior to the date by which such notice of redemption must be given to Holders in accordance with this Section 3.03 and the text
of such notice is completed by the Company. 
  
 Section 3.04. Effect of Notice of Redemption. Once notice of redemption is given, Securities called for redemption become due and payable on the Redemption Date and at the Redemption Price stated in the notice (except for
Securities which are converted in accordance with the terms of this Indenture) and from and after such date (unless the Company shall default in the payment of the Redemption Price) Interest and Additional Interest, if any, on such Securities shall
cease to accrue. Upon surrender to the Paying Agent, such Securities shall be paid at the Redemption Price. 
  
 Section 3.05. Deposit of Redemption Price. Prior to 10:00 a.m. (New York City time), on the Redemption Date, the Company shall deposit with
the Paying Agent (or if the Company or a Subsidiary or an Affiliate of either of them is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the Redemption Price of all Securities to be redeemed on that date other than
Securities or portions of Securities called for redemption which on or prior thereto have been delivered by the Company to the Trustee for cancellation or have been converted. The Paying Agent shall as promptly as practicable return to the Company
any money not required for that purpose because of conversion of Securities pursuant to Article 11. If such money is then held by the Company in trust and is not required for such purpose it shall be discharged from such trust. 
  
 Section 3.06. Securities Redeemed in Part. Upon surrender of a
Security that is redeemed in part, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Security in an authorized denomination equal in principal amount to the unredeemed portion of the Security surrendered.

  
 Section 3.07. Repurchase of Securities by the Company
at Option of the Holder. Debentures shall be purchased by the Company at the option of the Holder on April 15, 2009, April 15, 2013, April 15, 2015 and April 15, 2020 (each, a “Repurchase Date”), in
each case at a purchase price in cash equal to 100% of the principal amount of those Securities, plus any accrued and unpaid Interest and accrued and unpaid Additional Interest, if any, on those Securities, to (but excluding) such Repurchase Date
(the “Repurchase Price”); provided that if any such Repurchase Date falls after an Interest Record Payment Date and on or prior to the related Interest Payment Date, the Repurchase Price shall only be 100% of the principal
amount of those Securities and the Company shall pay such accrued and unpaid Interest, including accrued and unpaid Additional Interest, if any, on such Interest Payment Date to the Holder of the Securities on such Interest Record Date. Not later
than 20 Business Days prior to any Repurchase Date, the Company shall mail a Company Notice by first class mail to the Trustee 
  

 30 








 and to each Holder (and to beneficial owners as required by applicable law). The Company Notice shall include a form of
Repurchase Notice to be completed by a Holder and shall state: 
  
 (a) the Repurchase Price, the Repurchase Date and the Conversion Rate; 
  
 (b) the name and address of the Paying Agent and the Conversion Agent; 
  
 (c) that Securities as to which a Repurchase Notice has been given may be converted if they are otherwise
convertible only in accordance with Article 11 hereof and the terms of the Securities if the applicable Repurchase Notice has been withdrawn in accordance with the terms of this Indenture; 
  
 (d) that Securities must be surrendered to the Paying Agent
to collect payment; 
  
 (e) that the Repurchase
Price for any Security as to which a Repurchase Notice has been given and not withdrawn will be paid promptly following the later of the Business Day immediately following the Repurchase Date and the time of surrender of such Security as described
in (d); 
  
 (f) the procedures the Holder must
follow to exercise its repurchase rights under this Section 3.07 and a brief description of those rights; 
  
 (g) briefly, the conversion rights, if any, with respect to the Securities; 
  
 (h) the procedures for withdrawing a Repurchase Notice; 
  
 (i) that, unless the Company defaults in making payment on
Securities for which a Repurchase Notice has been submitted, Interest or Additional Interest, if any, on such Securities will cease to accrue immediately after the Repurchase Date; and 
  
 (j) the CUSIP, ISIN or other similar number(s), as the case may be, of the Securities. 
  
 At the Company’s request, the Trustee shall give such Company Notice in
the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Company Notice shall be prepared by the Company. 
  

 31 








 Purchases of Securities hereunder shall be made, at the option of the Holder thereof, upon: 

 
 (i) delivery to the Paying Agent by the Holder of a
written notice of repurchase (a “Repurchase Notice”) during the period beginning at any time from the opening of business on the date that is 20 Business Days prior to the relevant Repurchase Date until the close of business on the
Repurchase Date stating: 
  
 (A) the certificate
number of the Security which the Holder will deliver to be purchased or the appropriate Depositary procedures if Certificated Securities have not been issued for such Security, 
  
 (B) the portion of the principal amount of the Security which the Holder will deliver to be purchased, which
portion must be in principal amounts of $1,000 or an integral multiple of $1,000, and 
  
 (C) that such Security shall be purchased by the Company as of the Repurchase Date pursuant to the terms and conditions specified in this
Indenture; and 
  
 (ii) delivery of such Security
to the Paying Agent at any time after delivery of the Repurchase Notice (together with all necessary endorsements) at the offices of the Paying Agent, such delivery being a condition to receipt by the Holder of the Repurchase Price therefor;
provided, however, that such Repurchase Price shall be so paid pursuant to this Section 3.07 only if the Security so delivered to the Paying Agent shall conform in all respects to the description thereof in the related Repurchase Notice.

  
 The Company shall purchase from the Holder thereof, pursuant
to this Section 3.07, a portion of a Security, if the principal amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to the purchase of all of a Security also apply to the purchase of such
portion of such Security. 
  
 Notwithstanding anything herein to
the contrary, any Holder delivering to the Paying Agent the Repurchase Notice contemplated by this Section 3.07 shall have the right to withdraw such Repurchase Notice at any time prior to the close of business on the Repurchase Date by
delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.09. 
  
 The Paying Agent shall promptly notify the Company of the receipt by it of any Repurchase Notice or written notice of withdrawal thereof. 
  

 32 








 Section 3.08. Repurchase of Securities at Option of the Holder upon a Designated Event.

  
 (a) If a Change of Control (subject to certain exceptions set
forth below) or a Termination of Trading occurs (each such event, a “Designated Event”), Securities not previously converted, purchased or redeemed by the Company shall be purchased by the Company, at the option of the Holder
thereof, at a purchase price equal to 100% of the principal amount of those Securities, plus any accrued and unpaid Interest and accrued and unpaid Additional Interest, if any, on those Securities (the “Designated Event Repurchase
Price”) to, but not including, a date selected by the Company that is no less than 20 nor more than 35 days following the date of the notice of a Designated Event delivered by the Company pursuant to Section 3.08(d) (the
“Designated Event Repurchase Date”), subject to satisfaction by or on behalf of the Holder of the requirements set forth in Section 3.08(e). If the Designated Event Repurchase Date falls after an Interest Record Date and on or
prior to the related Interest Payment Date, the Designated Event Repurchase Price shall be only 100% of the principal amount of those Securities and the Company shall pay such accrued and unpaid Interest on such Interest Payment Date to the Holder
of the Securities on such Interest Record Date. 
  
 (b) A
“Change of Control” will be deemed to have occurred at such time after the original issuance of the Securities when any of the following has occurred: 
  
 (i) the acquisition by any Person, including any syndicate or group deemed to be a “person”
under Section 13(d)(3) of the Exchange Act of beneficial ownership, directly or indirectly, through a purchase, merger or other acquisition transaction or series of purchase, merger or other acquisition transactions, of shares of the Capital
Stock of the Company entitling that Person to exercise 50% or more of the total voting power of all shares of the Capital Stock of the Company entitled to vote generally in elections of directors, other than any acquisition by the Company, any
Subsidiary of the Company, or any of the employee benefit plans of the Company (except that any of those Persons shall be deemed to have beneficial ownership of all securities it has the right to acquire, whether the right is currently exercisable
or is exercisable only upon the occurrence of a subsequent condition); 
  
 (ii) the first day on which individuals who prior to such date constituted the Board of Directors (together with any new directors whose election by the Board of Directors or whose nomination for election by
stockholders of the Company was approved by a vote of a majority of the Board of Directors then still in office who were either directors prior to such date or whose election or nomination for election was previously so approved) cease for any
reason to constitute a majority of the Board of Directors then in office; or

all of the assets of the Company) in connection with which all or substantially all of the Common Stock or assets of the Company are exchanged for, converted into, acquired for or constitute solely the right to receive cash, securities or other
property. 
  
 For the purposes of this Section 3.08(b),
(x) whether a person is a “beneficial owner” shall be determined in accordance with Rule 13d-3 under the Exchange Act and (y) the term “person” includes any syndicate or group that would be deemed to be a
“person” under Section 13(d)(3) of the Exchange Act. 
  
 Notwithstanding the foregoing, it shall not be a Change of Control pursuant to Section 3.08(b)(iii) if 90% or more of the consideration received by stockholders of the Company in the transaction or transactions
(other than cash payments for fractional shares and cash payments made in respect of dissenters’ appraisal rights) constituting a Change of Control consists of shares of Capital Stock that have no preference in respect of dividends or of
amounts payable in the event of any voluntary or involuntary liquidation, dissolution or winding up of the issuer thereof and that are traded or scheduled to be traded immediately following such transaction or event on a national securities exchange
or the Nasdaq National Market. 
  
 (c) A “Termination of
Trading” will be deemed to have occurred if the Common Stock (or other common stock into which the Securities are then convertible) is neither listed for trading on a United States national securities exchange nor approved for trading on
the NASDAQ National Market. 
  
 (d) Within 30 days after the
occurrence of a Designated Event, the Company shall mail a Company Notice of the Designated Event by first class mail to the Trustee and to each Holder (and to beneficial owners as required by applicable law). The Company Notice shall include a form
of Designated Event Repurchase Notice to be completed by the Holder and shall state:

 34 








 (vi) the Conversion Rate; 
  
 (vii) that the Securities as to which a Designated Event Repurchase Notice has been given may be converted
if they are otherwise convertible pursuant to Article 11 hereof only if the Designated Event Repurchase Notice has been withdrawn in accordance with the terms of this Indenture; 
  
 (viii) that the Securities must be surrendered to the Paying Agent to collect payment; 
  
 (ix) that the Designated Event Repurchase Price for any
Security as to which a Designated Event Repurchase Notice has been duly given and not withdrawn will be paid promptly following the later of the Business Day immediately following the Designated Event Repurchase Date and the time of surrender of
such Security as described in clause (viii); 
  
 (x) briefly, the procedures the Holder must follow to exercise rights under this Section 3.08; 
  
 (xi) briefly, the conversion rights, if any, on the Securities; 
  
 (xii) the procedures for withdrawing a Designated Event Repurchase Notice; 
  
 (xiii) that, unless the Company defaults in making payment
of such Designated Event Repurchase Price, Interest and Additional Interest, if any, on Securities surrendered for purchase by the Company will cease to accrue immediately after the Designated Event Repurchase Date; and 
  
 (xiv) the CUSIP, ISIN or other similar number(s), as the
case may be, of the Securities. 
  
 At the Company’s request,
the Trustee shall give such Company Notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Company Notice shall be prepared by the Company. 
  
 (e) A Holder may exercise its rights specified in this Section 3.08 upon
delivery of a written notice of purchase (a “Designated Event Repurchase Notice”) to the Paying Agent at any time on or prior to the close of business on the Designated Event Repurchase Date stating: 
  
 (i) the certificate number of the Security which the Holder
will deliver to be purchased or the appropriate Depositary procedures if Certificated Securities have not been issued; 
  

 35 








 (ii) the portion of the principal amount of the Security which the Holder will deliver to
be purchased, which portion must be $1,000 or an integral multiple of $1,000; and 
  
 (iii) that such Security shall be purchased pursuant to the terms and conditions specified in this Indenture. 
  
 The Company shall purchase from the Holder thereof, pursuant to this
Section 3.08, a portion of a Security if the principal amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to the purchase of all of a Security also apply to the purchase of such portion
of such Security. 
  
 Notwithstanding anything herein to the
contrary, any Holder delivering to the Paying Agent the Designated Event Repurchase Notice contemplated by this Section 3.08(e) shall have the right to withdraw such Designated Event Repurchase Notice at any time prior to the close of business
on the Designated Event Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.09. 
  
 The Paying Agent shall promptly notify the Company of the receipt by it of any Designated Event Repurchase Notice or written withdrawal thereof.

  
 Section 3.09. Effect of Repurchase Notice or
Designated Event Repurchase Notice. 
  
 (a) Payment of the
Repurchase Price or the Designated Event Repurchase Price for a Security for which a Repurchase Notice or a Designated Event Repurchase Notice, as the case may be, has been delivered and not withdrawn in accordance with Section 3.09(b) or
Section 3.09(c), as the case may be, is conditioned upon book-entry transfer or delivery of the Security, together with necessary endorsements, to the Paying Agent, or any other office of the Paying Agent, at any time after delivery of the
Repurchase Notice or the Designated Event Repurchase Notice, as the case may be. The Company shall pay the Repurchase Price or the Designated Event Repurchase Price to the Paying Agent as promptly as reasonably practicable following the later of the
Repurchase Date or the Designated Event Repurchase Date or the time of book-entry transfer or delivery of the purchased Securities. If the Paying Agent holds money or securities sufficient to pay the Repurchase Price or the Designated Event
Repurchase Price on the Business Day immediately following the Repurchase Date or the Designated Event Repurchase Date, then: 
  
 (i) the purchased Securities will cease to be outstanding and interest and Additional Interest, if any, will cease to accrue, and

  
 (ii) all other rights of the Holders of such
purchased Securities will terminate (other than the right to receive the Repurchase Price or the Designated Event Repurchase Price upon delivery or transfer of such purchased Securities), 
  

 36 








 in each case, whether or not book-entry transfer of the purchased Securities is made or whether or not the purchased
Securities are delivered to the Paying Agent. 
  
 Securities in
respect of which a Repurchase Notice or Designated Event Repurchase Notice has been given by the Holder thereof may not be converted pursuant to Article 11 hereof on or after the date of the delivery of such Repurchase Notice or Designated Event
Repurchase Notice unless such Repurchase Notice or Designated Event Repurchase Notice has first been validly withdrawn in accordance with Section 3.09(b) or Section 3.09(c). 
  
 (b) A Repurchase Notice or Designated Event Repurchase Notice may be withdrawn by means of a written notice of withdrawal
delivered to the office of the Paying Agent in accordance with the Repurchase Notice or Designated Event Repurchase Notice, as the case may be, at any time prior to the close of business on the Repurchase Date or the Designated Event Repurchase
Date, as the case may be, specifying: 
  
 (i) the
certificate number of the Security in respect of which such notice of withdrawal is being submitted or the appropriate Depositary procedures if Certificated Securities have not been issued for such Security, 
  
 (ii) the principal amount of the Security with respect to
which such notice of withdrawal is being submitted, and 
  
 (iii) the principal amount, if any, of such Security which remains subject to the original Repurchase Notice or Designated Event Repurchase Notice, as the case may be, and which has been or will be delivered for
purchase by the Company. 
  
 (c) There shall be no purchase of any
Securities pursuant to Section 3.07 or 3.08 if (prior to, on or after, as the case may be, the giving, by the Holders of such Securities, of the required Repurchase Notice or Designated Event Repurchase Notice, as the case may be) the principal
amount of the Securities has been accelerated and such acceleration has not been rescinded. The Paying Agent will promptly return to the respective Holders thereof any Securities (x) with respect to which a Repurchase Notice or Designated Event
Repurchase Notice, as the case may be, has been withdrawn in compliance with this Indenture, or (y) held by it during the continuance of any acceleration of the principal amount of the Securities in which case, upon such return, the Repurchase
Notice or Designated Event Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 
  

 37 








 Section 3.10. Deposit of Repurchase Price or Designated Event Repurchase Price. Prior to
10:00 a.m. (local time in The City of New York) on the Business Day immediately following the Repurchase Date or the Designated Event Repurchase Date, as the case may be, the Company shall deposit with the Paying Agent (or, if the Company or a
Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 2.04) an amount of cash in immediately available funds sufficient to pay the aggregate Repurchase Price or
Designated Event Repurchase Price, as the case may be, of all the Securities or portions thereof which are to be purchased as of the Repurchase Date or Designated Event Repurchase Date, as the case may be. 
  
 Section 3.11. Securities Purchased in Part. Any Certificated
Security which is to be purchased only in part shall be surrendered at the office of the Paying Agent (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 such Holder’s attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge, a new
Security or Securities, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Security so surrendered that is not purchased. 
  
 Section 3.12. Covenant to Comply with Securities Laws upon Purchase
of Securities. When complying with the provisions of Section 3.07, Section 3.08 or Section 3.09 hereof the Company shall (i) comply with Rule 13e-4 and Rule 14e-1 (or any other tender offer rules or successor provisions)
under the Exchange Act, (ii) file Schedule TO (or any other required schedule or successor schedule, form or report) under the Exchange Act, and (iii) otherwise comply with all Federal and state securities laws so as to permit the rights
and obligations under Section 3.07, Section 3.08 and Section 3.09 to be exercised in the time and in the manner specified Section 3.07, Section 3.08 and Section 3.09. 
  
 Section 3.13. Repayment to the Company. The Trustee and the
Paying Agent shall return to the Company any cash that remains unclaimed as provided in Section 9.02 hereof and Section 11 of the Securities, together with interest, if any, thereon (subject to the provisions of Section 8.01(f)), held
by them for the payment of the Repurchase Price or Designated Event Repurchase Price, as the case may be; provided, however, that to the extent that the aggregate amount of cash deposited by the Company pursuant to Section 3.10 exceeds
the aggregate Repurchase Price or Designated Event Repurchase Price, as the case may be, of the Securities or portions thereof that the Company is obligated to purchase as of the Repurchase Date or Designated Event Repurchase Date, as the case may
be, then, unless otherwise agreed in writing with the Company, promptly after the Business Day following the Repurchase Date or Designated Event Repurchase Date, as the case may be, the Trustee shall return any such excess to the Company together
with interest thereon (subject to the provisions of Section 8.01(f)). 
  

 38 








 ARTICLE 4 
 SUBORDINATION 
  
 Section 4.01. Agreement of Subordination. The Company covenants and agrees, and each Holder of Securities issued hereunder by its acceptance thereof likewise covenants and agrees, that all Securities shall be issued subject to
the provisions of this Article 4; and each Person holding any Security, whether upon original issue or upon transfer, assignment or exchange thereof, accepts and agrees to be bound by such provisions. 
  
 The payment of the principal, interest and Additional Interest, if any, on
all Securities (including, but not limited to, the Redemption Price and the Designated Event Repurchase Price with respect to the Securities subject to redemption or repurchase in accordance with Article 3 and the payment of any cash upon conversion
in accordance with Article 11) issued hereunder shall, to the extent and in the manner hereinafter set forth, be (i) subordinated and subject in right of payment to the prior payment in full in cash or other payment satisfactory to the holders
of Senior Debt of all Senior Debt, whether outstanding at the date of this Indenture or thereafter incurred; (ii) pari passu in right of payment to all Senior Subordinated Debt and (iii) senior in right of payment to all Subordinated Debt.

  
 No provision of this Article 4 shall prevent the occurrence of
any default or Event of Default hereunder. 
  
 Section 4.02. Payments to Holders. No payment shall be made with respect to the principal of, or interest or Additional Interest, if any, on the Securities (including, but not limited to, the Redemption Price, the Repurchase
Price and the Designated Event Repurchase Price with respect to the Securities subject to redemption or purchase in accordance with Article 3 and any payment of cash upon conversion in accordance with Article 11), except payments and distributions
made by the Trustee as permitted by the first or second paragraph of Section 4.05, if: 
  
 (a) a default in the payment of principal, premium, interest, rent or other obligations due on any Senior Debt 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) (a “Payment
Default”); or 
  
 (b) a default, other
than a payment default, on any Designated Senior Debt occurs and is continuing that then permits holders of such Designated Senior Debt (or any Representative) to accelerate its maturity (a “Non-Payment Default”) and a Responsible
Officer of the Trustee receives at the Corporate Trust Office a written notice of the default (a “Payment Blockage Notice”) from a Representative of Designated Senior Debt. 
  

 39 








 Notwithstanding the foregoing, not more than one Payment Blockage Notice may be given in any consecutive
360-day period, irrespective of the number of defaults with respect to Designated Senior Debt during such period. No default that existed or was continuing on the date of delivery of any Payment Blockage Notice with respect to the Designated Senior
Debt whose holders delivered the Payment Blockage Notice may be made the basis of a subsequent Payment Blockage Notice by the holders of such Designated Senior Debt, whether or not within a period of 360 consecutive days, unless the default has been
cured or waived for a period of not less than 90 consecutive days. 
  
 The Company may and shall resume payments on and distributions in respect of the Securities upon the earlier of: 
  
 (a) in the case of a Payment Default, the date upon which the default is cured or waived or ceases to exist, or 
  
 (b) in the case of a Non-Payment Default, the earlier of the
date on which such default is cured or waived or ceases to exist, in each case as and to the extent permitted under the documentation for the Designated Senior Debt, or 179 days pass after the date on which the applicable Payment Blockage Notice is
received, in each case, unless the maturity of the Designated Senior Debt has been accelerated or this Article 4 otherwise prohibits the payment or distribution at the time of such payment or distribution. 
  
 Upon any payment by the Company, or distribution of assets of the Company of
any kind or character, whether in cash, property or securities, to creditors upon any dissolution or winding-up or liquidation or reorganization of the Company (whether voluntary or involuntary) or in bankruptcy, insolvency, receivership or similar
proceedings, all amounts due or to become due upon all Senior Debt shall first be paid in full in cash, or other payments satisfactory to the holders of Senior Debt before any payment of cash, property or securities is made on account of the
principal of, interest or Additional Interest, if any, on, or with respect to the conversion of, the Securities (except payments made pursuant to Article 9 from monies deposited with the Trustee pursuant thereto prior to commencement of proceedings
for such dissolution, winding-up, liquidation or reorganization); and upon any such dissolution or winding-up or liquidation or reorganization of the Company or bankruptcy, insolvency, receivership or other proceeding, any payment by the Company, or
distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the Holders of the Securities or the Trustee would be entitled, except for the provision of this Article 4, shall (except as aforesaid)
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 
  

 40 








 Trustee under this Indenture if received by them or it, directly to the holders of Senior Debt (pro rata to such holders
on the basis of the respective amounts of Senior Debt held by such holders, or as otherwise required by law or a court order) or their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any
instruments evidencing any Senior Debt may have been issued, as their respective interests may appear, to the extent necessary to pay all Senior Debt in full in cash, or other payment satisfactory to the holders of Senior Debt, 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. 
  
 For purposes of this Article 4, the words, “cash, property or securities” shall not be deemed to include shares of
Capital Stock of the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment, the payment of which is subordinated at least to the extent provided in this
Article 4 with respect to the Securities to the payment of all Senior Debt which may at the time be outstanding; provided that (i) the Senior Debt is assumed by the new corporation, if any, resulting from any reorganization or readjustment, and
(ii) the rights of the holders of Senior Debt (other than leases which are not assumed by the Company or the new corporation, as the case may be) are not, without the consent of such holders, altered by such reorganization or readjustment. The
consolidation of the Company with, or the merger of the Company into, another corporation or the liquidation or dissolution of the Company following the conveyance, transfer or lease of all or substantially all its property to another corporation
upon the terms and conditions provided for in Article 6 shall not be deemed a dissolution, winding-up, liquidation or reorganization for the purposes of this Section 4.02 if such other corporation shall, as a part of such consolidation, merger,
conveyance, transfer or lease, comply with the conditions stated in Article 6. 
  
 If payment of the Securities is accelerated because of an Event of Default, the Company shall promptly notify holders of Senior Debt or their Representatives of such acceleration. The Company shall not pay the
Securities until five days after the holders or Representatives for the holders of Senior Debt receive notice of the acceleration and after which the Company shall pay the Securities only if this Article 4 otherwise permits payment at that time.

  
 In the event that, notwithstanding the foregoing provisions,
any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities (including, without limitation, by way of setoff or otherwise), prohibited by the foregoing, shall be received by the Trustee or
the Holders of the Securities before all Senior Debt is paid in full, in cash or other payment satisfactory to the holders of Senior Debt, or provision is made for such payment thereof in accordance with its terms in cash or other payment
satisfactory to the holders of Senior Debt, such payment or distribution shall be held in trust for the benefit of and shall be paid over or delivered to the holders of Senior Debt or their Representative or Representatives, as their respective
interests may appear, 
  

 41 








 as calculated by the Company, for application to the payment of all Senior Debt remaining unpaid to the extent necessary
to pay all Senior Debt in full, in cash or other payment satisfactory to the holders of Senior Debt or their Representative, after giving effect to any concurrent payment or distribution to or for the holders of such Senior Debt. 
  
 Nothing in this Section 4.02 shall apply to claims of, or payments to,
the Trustee under or pursuant to Section 7.10 and Section 8.07. This Section 4.02 shall be subject to the further provisions of Section 4.05. 
  
 Section 4.03. Subrogation of Securities. Subject to the payment in full, in cash or other payment satisfactory
to the holders of Senior Debt, of all Senior Debt, the rights of the Holders of the Securities shall be subrogated to the extent of the payments or distributions made to the holders of such Senior Debt pursuant to the provisions of this Article 4
(equally and ratably with the holders of all Senior Subordinated Debt) to the rights of the holders of Senior Debt to receive payments or distributions of cash, property or securities of the Company applicable to the Senior Debt until the principal,
interest or Additional Interest, if any, on the Securities shall be paid in full in cash or other payment satisfactory to the holders of Securities; and, for the purposes of such subrogation, no payments or distributions to the holders of the 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 4, and no payment over pursuant to the provisions of this Article 4, to or for the benefit of
the holders of Senior Debt by Holders of the Securities or the Trustee, shall, as between the Company, its creditors other than holders of Senior Debt, and the Holders of the Securities, be deemed to be a payment by the Company to or on account of
the Senior Debt; and no payments or distributions of cash, property or securities to or for the benefit of the Holders of the Securities pursuant to the subrogation provisions of this Article 4, which would otherwise have been paid to the holders of
Senior Debt shall be deemed to be a payment by the Company to or for the account of the Securities. It is understood that the provisions of this Article 4 are and are intended solely for the purposes of defining the relative rights of the Holders of
the Securities, on the one hand, and the holders of the Senior Debt, on the other hand. 
  
 Nothing contained in this Article 4 or elsewhere in this Indenture or in the Securities is intended to or shall impair, as among the Company, its creditors other than the holders of Senior Debt, and the Holders of the
Securities, the obligation of the Company, which is absolute and unconditional, to pay to the Holders of the Securities the principal of, interest or Additional Interest, if any, on the Securities as and when the same shall become due and payable in
accordance with their terms, or is intended to or shall affect the relative rights of the Holders of the Securities and creditors of the Company other than the holders of the Senior Debt, nor shall anything herein or therein prevent the Trustee or
the Holder of any Security from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article 4 of the holders of Senior Debt in respect of cash, property or
securities of the Company received upon the exercise of any such remedy. 
  

 42 








 Upon any payment or distribution of assets of the Company referred to in this Article 4, the Trustee,
subject to the provisions of Section 8.01, and the Holders of the Securities shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which such bankruptcy, dissolution, winding-up, liquidation or
reorganization proceedings are pending, or a certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent or other person making such payment or distribution, delivered to the Trustee or to the Holders of the Securities, for the
purpose of ascertaining the persons entitled to participate in such distribution, the holders of the Senior Debt and other indebtedness of the Company, the amount thereof or payable thereon and all other facts pertinent thereto or to this Article 4.

  
 Section 4.04. Authorization to Effect Subordination.
Each Holder of a Security by the Holder’s acceptance thereof authorizes and directs the Trustee on the Holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article 4
and appoints the Trustee to act as the Holder’s attorney-in-fact for any and all such purposes. If the Trustee does not file a proper proof of claim or proof of debt in the form required in any proceeding referred to in Section 4.03 hereof
at least 30 days before the expiration of the time to file such claim, the holders of any Senior Debt or their representatives are hereby authorized to file an appropriate claim for and on behalf of the Holders of the Securities. 
  
 Section 4.05. Notice to Trustee. The Company shall give prompt
written notice in the form of an Officers’ Certificate to a Responsible Officer of the Trustee and to any Paying Agent of any fact known to the Company which would prohibit the making of any payment of monies to or by the Trustee or any Paying
Agent in respect of the Securities pursuant to the provisions of this Article 4. Notwithstanding the provisions of this Article 4 or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts
which would prohibit the making of any payment of monies to or by the Trustee in respect of the Securities pursuant to the provisions of this Article 4, unless and until a Responsible Officer of the Trustee shall have received written notice thereof
at the Corporate Trust Office from the Company (in the form of an Officers’ Certificate) or a Representative or a Holder or Holders of Senior Debt or from any trustee thereof; and before the receipt of any such written notice, the Trustee,
subject to the provisions of Section 8.01, shall be entitled in all respects to assume that no such facts exist; provided that, if on a date not less than two Business Days prior to the date upon which by the terms hereof any such monies
may become payable for any purpose (including, without limitation, the payment of the principal of, interest or Additional Interest, if any, on any Security) the Trustee shall not have received, with respect to such monies, the notice provided for
in this Section 4.05, then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such 
  

 43 








 monies and to apply the same to the purpose for which they were received, and shall not be affected by any notice to the
contrary which may be received by it on or after such prior date. Notwithstanding anything in this Article 4 to the contrary, nothing shall prevent any payment by the Trustee to the Holders of monies deposited with it pursuant to Article 9, and any
such payment shall not be subject to the provisions of this Article 4. 
  
 The Trustee, subject to the provisions of Section 8.01, shall be entitled to rely on the delivery to it of a written notice by a Representative or a person representing himself to be a holder of Senior Debt (or a trustee on behalf of
such holder) to establish that such notice has been given by a Representative or a holder of Senior Debt. 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 4, 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 4, 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 4.06. Trustee’s Relation to Senior Debt. The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article 4 in respect of any Senior Debt at any time held
by it, to the same extent as any other holder of Senior Debt, and nothing in Section 8.11 or elsewhere in this Indenture shall deprive the Trustee of any of its rights as such holder. 
  
 With respect to the holders of Senior Debt, the Trustee undertakes to perform
or to observe only such of its covenants and obligations as are specifically set forth in this Article 4, and no implied covenants or obligations with respect to the holders of Senior Debt shall be read into this Indenture against the Trustee. The
Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt and, subject to the provisions of Section 8.01, the Trustee shall not be liable to any holder of Senior Debt if it shall pay over or deliver to Holders of
Securities, the Company or any other Person money or assets to which any holder of Senior Debt shall be entitled by virtue of this Article 4 or otherwise. 
  
 Section 4.07. No Impairment of Subordination. 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, or by any noncompliance by the Company with the terms,
provisions and covenants of this Indenture, regardless of any knowledge thereof which any such holder may have or otherwise be charged with. 
  

 44 








 Section 4.08. Certain Conversions Not Deemed Payment. For the purposes of this Article 4
only, the issuance and delivery of junior securities upon conversion of Securities in accordance with Article 11 shall not be deemed to constitute a payment or distribution on account of the principal of such Security or interest. For the purposes
of this Section 4.08, the term “junior securities” means (a) shares of any Capital Stock of any class of the Company, or (b) securities of the Company which 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. Nothing contained in this Article 4 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, the right, which is absolute and unconditional, of the Holder of any Security to convert such
Security in accordance with Article 11. 
  
 Section 4.09.
Article Applicable to Paying Agents. If 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 (unless the context
otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article in addition to or in place of the Trustee; provided,
however, that the first paragraph of Section 4.05 shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as Paying Agent. 
  
 Section 4.10. Senior Debt Entitled to Rely. The holders of Senior Debt (including, without limitation,
Designated Senior Debt) shall have the right to rely upon this Article 4, and no amendment or modification of the provisions contained herein shall diminish the rights of such holders unless such holders shall have agreed in writing thereto.

  
 ARTICLE 5 
 COVENANTS 
  
 Section 5.01. Payment of Securities. The Company shall promptly make all payments in respect of the Securities on the dates and in the manner
provided in the Securities or pursuant to this Indenture. Any amounts of cash in immediately available funds to be given to the Trustee or Paying Agent, shall be deposited with the Trustee or Paying Agent by 10:00 a.m., New York City time, by the
Company. The principal amount of, and Interest and Additional Interest, if any, on the Securities, and the Redemption Price, Repurchase Price and the Designated Event Repurchase Price shall be considered paid on the applicable date due if on such
date (or, in the case of a Repurchase Price or a Designated Event Repurchase Price, on the Business Day immediately following the applicable Repurchase Date or Designated Event Repurchase Date, as the case may be) the Trustee or the Paying Agent
holds, in accordance with this Indenture, cash sufficient to pay all such amounts then due.

 Section 5.02. SEC and Other Reports. The Company shall file with the Trustee, within 15 days
after it files such annual and quarterly reports, information, documents and other reports with the SEC, copies of its annual report and of the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC
may by rules and regulations prescribe) which the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. The Company shall comply with the other provisions of TIA Section 314(a). Delivery of such
reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such 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 conclusively on Officers’ Certificates). 
  
 Section 5.03. Compliance Certificate. The Company shall deliver to the Trustee within 120 days after the end of
each fiscal year of the Company (beginning with the fiscal year ending December 31, 2005) an Officers’ Certificate, stating whether or not to the knowledge of the signers thereof, the Company is in default in the performance and observance
of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and if the Company shall be in default, specifying all such defaults and the nature and status
thereof of which they may have knowledge and otherwise comply with Section 314(a)(4) of the TIA. 
  
 The Company shall, so long as any of the Securities are outstanding, deliver to the Trustee, forthwith upon any executive officer of the Company becoming
aware of any default or Event of Default in respect of the performance or observance of any covenant, agreement or condition contained in this Indenture or the Securities, but in any event not later than twenty Business Days after the occurrence
thereof, an Officers’ Certificate specifying such default or Event of Default and what action the Company is taking or proposes to take with respect thereto. 
  
 Section 5.04. Further Instruments and Acts. The Company will execute and deliver such further instruments and do
such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture. 
  
 Section 5.05. Maintenance of Office or Agency. The Company will maintain in New York, New York, an office or agency of the Trustee, Registrar,
Paying Agent and Conversion Agent where Securities may be presented or surrendered for payment, where Securities may be surrendered for registration of transfer, exchange, purchase, redemption or conversion and where notices and 
  

 46 








 demands to or upon the Company in respect of the Securities and this Indenture may be served. The Corporate Trust Office
shall initially be such office or agency for all of the aforesaid purposes. The Company shall give prompt written notice to the Trustee of the location, and of any change in the location, of any such office or agency (other than a change in the
location of the office of the Trustee). If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be
made or served at the address of the Trustee set forth in Section 13.02. 
  
 The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in New York, New York, for such purposes. 
  
 Section 5.06. Delivery of Certain Information. At any time when
the Company is not subject to Section 13 or 15(d) of the Exchange Act, upon the request of a Holder or any beneficial owner of Securities or holder or beneficial owner 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 or any beneficial owner of Securities or holder or beneficial owner of shares of Common Stock, or to a prospective purchaser of any such security
designated by any such 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 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. Whether a person is a beneficial owner shall be determined by the Company to the Company’s reasonable satisfaction.

  
 Section 5.07. Additional Interest Notice. In the
event that the Company is required to pay Additional Interest to holders of Securities pursuant to the Registration Rights Agreement, the Company will provide written notice (the “Additional Interest Notice”) to the Trustee of its
obligation to pay Additional Interest prior to the Interest Record Date for the Interest Payment Date on which Additional Interest will be paid, and the Additional Interest Notice shall set forth the amount of Additional Interest to be paid by the
Company on such Interest Payment Date. The Trustee shall not at any time be under any duty to any holder of Securities to determine the Additional Interest, or with respect to the nature, extent or calculation of the amount of Additional Interest
when made, or with respect to the method employed in such calculation of the Additional Interest.

into common stock or other securities issued by any other Person, such Person fully and unconditionally guarantees all of the obligations of the Company or such successor under the Securities and the Indenture; 
  
 (c) immediately after giving effect to such transaction, no Event of Default,
and no event that, after notice or lapse of time or both, would become an Event of Default, shall have occurred and be continuing; and 
  
 (d) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger,
conveyance, transfer or lease and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, comply with this Article 6 and that all conditions precedent herein provided for relating to such
transaction have been satisfied. 
  
 The successor Person formed
by such consolidation or into which the Company is merged or the successor Person to which such conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this
Indenture with the same effect as if such successor had been named as the Company herein; and thereafter, except in the case of a lease and obligations the Company may have under a supplemental indenture, the Company shall be discharged from all
obligations and covenants under this Indenture and the Securities. Subject to Section 10.06, the Company, the Trustee and the successor Person shall enter into a supplemental indenture to evidence the succession and substitution of such

 (h) a failure to pay when due at maturity or a default, event of default or other similar condition or event (however described) that
results in the acceleration of maturity of any indebtedness of the Company or any Designated Subsidiary in an aggregate amount of $25 million or more, unless the acceleration is rescinded, stayed or annulled within 30 days after receipt by the
Company of a Notice of Default; 
  

 49 








 (i) the entry by a court having jurisdiction in the premise of (A) a decree or order
for relief in respect of the Company, any Designated Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Designated Subsidiary in an involuntary case or proceeding under any applicable bankruptcy,
insolvency, reorganization or other similar law or (B) a decree or order adjudging the Company or any Designated Subsidiary, a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or
composition of or in respect of the Company or any Designated Subsidiary under any applicable law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part
of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order described in Clause (A) or (B) above unstayed and in effect for a
period of 90 consecutive days; and 
  
 (j) the
commencement by the Company, any Designated Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Designated Subsidiary of a voluntary case or proceeding under any applicable bankruptcy, insolvency,
reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by the Company or any Designated Subsidiary to the entry of a decree or order for relief in respect of the Company or
any Designated Subsidiary in an involuntary case or proceeding under any applicable bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against the Company, or the

benefit of creditors, or the admission by the Company or any Designated Subsidiary in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company or any Designated Subsidiary expressly in
furtherance of any such action. 
  
 For the avoidance of doubt,
clause (g) or (h) above shall not constitute an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% in aggregate principal amount of the Securities at the time outstanding notify the Company and the
Trustee, of such default and the Company does not cure such default (and such default is not waived) within the time specified in clause (g) or (h) above, as applicable, after actual receipt of such notice. Any such notice must specify the
default, demand that it be remedied and state that such notice is a “Notice of Default.” 
  

 50 








 The Trustee shall, within 90 days of the occurrence of an Event of Default known to it, give to the
Holders of the Securities notice of all uncured Events of Defaults known to it and written notice of any event which, with the giving of notice or the lapse of time, or both, would become an Event of Default, its status and what action the Company
is taking or proposes to take with respect thereto; provided, however, that the Trustee shall be protected in withholding such notice if it, in good faith, determines that the withholding of such notice is in the best interest of such
Holders, except in the case of an Event of Default specified in clauses (a) through (e) of this Section 7.01. 
  
 Section 7.02. Acceleration. If an Event of Default (other than an Event of Default specified in Section 7.01(i) or 7.01(j)) occurs and is
continuing (the default not having been cured or waived), the Trustee by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities at the time outstanding by notice to the Company and the Trustee, may
declare the principal amount of the Securities and any accrued and unpaid Interest and accrued and unpaid Additional Interest, if any, on all the Securities through the date of acceleration to be immediately due and payable. Upon such a declaration,
such accelerated amount shall be due and payable immediately. If an Event of Default specified in Section 7.01(i) or 7.01(j) occurs and is continuing, the principal amount of the Securities and any accrued and unpaid Interest and accrued and
unpaid Additional Interest, if any, on all the Securities through the date of acceleration shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Securityholders. The Holders of a
majority in aggregate principal amount of the Securities at the time outstanding, by notice to the Trustee (and without notice to any other Securityholder) may rescind an acceleration and its consequences if the rescission would not conflict with
any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of the principal amount of the Securities and any accrued and unpaid Interest and accrued and unpaid Additional Interest, if any, that have
become due solely as a result of acceleration. No such rescission shall affect any subsequent Event of Default or impair any right consequent thereto. 
  
 Section 7.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the
payment of the principal amount of the Securities and any accrued and unpaid Interest and accrued and unpaid Additional Interest, if any, on the Securities and any and all amounts due and owing to the Trustee under Section 8.07 or to enforce
the performance of any provision of the Securities or this Indenture. 
  
 The Trustee may maintain a proceeding even if the Trustee does not possess any of the Securities or does not produce any of the Securities in the proceeding. A delay or omission by the Trustee or any Securityholder in 
  

 51 








 exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a
waiver of, or acquiescence in, the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative. 
  
 Section 7.04. Waiver of Past Defaults. The Holders of a majority in aggregate principal amount of the Securities at the time outstanding, by
notice to the Trustee (and without notice to any other Securityholder), may waive an existing or past Event of Default and its consequences except (a) an Event of Default described in Section 7.01 clauses (a) through (e) or
(b) an Event of Default in respect of a provision that under Section 10.02 cannot be amended without the consent of the holder of each outstanding Security. When an Event of Default is waived, it is deemed cured, but no such waiver shall
extend to any subsequent or other Event of Default or impair any consequent right. This Section 7.04 shall be in lieu of Section 316(a)1(B) of the TIA and such Section 316(a)1(B) is hereby expressly excluded from this Indenture, as
permitted by the TIA. 
  
 Section 7.05. Control by
Majority. The Holders of a majority in aggregate principal amount of Securities at the time outstanding may direct, through the written consent of such Holders, the time, method and place of conducting any proceeding for any remedy available to
the Trustee or of exercising any trust or power conferred on the Trustee with respect to the Securities. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines in good faith
is unduly prejudicial to the rights of other Securityholders or would involve the Trustee in personal liability; provided that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.
This Section 7.05 shall be in lieu of Section 316(a)1(A) of the TIA and such Section 316(a)1(A) is hereby expressly excluded from this Indenture, as permitted by the TIA. 
  
 Section 7.06. Limitation on Suits. A holder of Securities may not pursue any remedy with respect to this
Indenture or the Securities, except in the case of an Event of Default specified in Section 7.01 clauses (a) through (e), unless: 
  
 (a) the Holder gives to the Trustee written notice stating that an Event of Default is continuing; 
  
 (b) the Holders of at least 25% in aggregate principal
amount of the Securities at the time outstanding make a written request to the Trustee to pursue the remedy; 
  
 (c) such Holder or Holders offer to the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense;

  
 (d) the Trustee does not comply with the
request within 60 days after receipt of such request and offer of security or indemnity; and 
  

 52 








 (e) the Holders of a majority in aggregate principal amount of the Securities at the time
outstanding do not give the Trustee a direction inconsistent with the request during such 60-day period. 
  
 A Securityholder may not use this Indenture to prejudice the rights of any other Securityholder or to obtain a preference or priority over any other
Securityholder. 
  
 Section 7.07. Rights of Holders to
Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of the principal amount of the Securities and any accrued and unpaid Interest and accrued and unpaid Additional Interest, if any,
in respect of the Securities held by such Holder, on or after the respective due dates expressed in the Securities or any Redemption Date, Repurchase Date or Designated Event Repurchase Date, and to convert the Securities in accordance with Article
11, or to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, shall not be impaired or affected adversely without the consent of such Holder. 
  
 Section 7.08. Collection Suit by Trustee. If an Event of Default
described in Section 7.01 clauses (a) through (e) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount owing with respect to the
Securities and the amounts provided for in Section 8.07. 
  
 Section 7.09. Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the
Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal amount of the Securities and any accrued and unpaid Interest and accrued
and unpaid Additional Interest, if any, in respect of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment
of any such amount) shall be entitled and empowered, by intervention in such proceeding or otherwise: 
  
 (a) to file and prove a claim for the whole principal amount of the Securities and any accrued and unpaid Interest and accrued and unpaid Additional
Interest, if any, and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel or any other amounts due the Trustee under Section 8.07) and of the Holders allowed in such judicial proceeding, and 
  
 (b) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian,

  

 53 








 receiver, assignee, trustee, liquidator, sequestrator or similar official in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 8.07. 
  
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
  
 Section 7.10. Priorities. Any money collected by the Trustee
pursuant to this Article 7, and, after an Event of Default, any money or other property distributable in respect of the Company’s obligations under this Indenture, shall be paid out in the following order: 
  
 FIRST: to the Trustee (including any predecessor Trustee) for amounts due
under Section 8.07; 
  
 SECOND: to the holders of Senior Debt
to the extent required by Article 4; 
  
 THIRD: to Securityholders
for amounts due and unpaid on the Securities for the principal amount of the Securities and any accrued and unpaid Interest and accrued and unpaid Additional Interest, if any, as the case may be, ratably, without preference or priority of any kind,
according to such amounts due and payable on the Securities; and 
  
 FOURTH: the balance, if any, to the Company. 
  
 The
Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this Section 7.10. At least 15 days before such record date, the Trustee shall mail to each Securityholder and the Company a notice that states the
record date, the payment date and the amount to be paid. 
  
 Section 7.11. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant (other than the Trustee) in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses,
against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 7.11 does not apply to a suit by the Trustee. 
  

 54 








 Section 7.12. Waiver of Stay, Extension or Usury Laws. The Company covenants (to the extent
that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury or other law wherever enacted, now or at any time hereafter
in force, which would prohibit or forgive the Company from paying all or any portion of the principal amount of the Securities and any accrued and unpaid Interest and accrued and unpaid Additional Interest, if any, on Securities, as contemplated
herein, or which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay
or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 
  
 ARTICLE 8 
 TRUSTEE 
  
 Section 8.01. Duties
of Trustee.  
  
 (a) If an Event of Default has occurred and

provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine such certificates and opinions to determine whether or not they conform to the requirements of this Indenture, but need not

 Section 8.04. Trustee’s Disclaimer. The Trustee makes no
representation as to and shall have no responsibility for the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use or application by the Company of the Securities or of the proceeds from
the Securities, it shall not be responsible for the correctness of any recital contained herein or for any statement in the registration statement for the Securities under the Securities Act or in any offering document for the Securities, the
Indenture or the Securities (other than its certificate of authentication), or the determination as to which beneficial owners are entitled to receive any notices hereunder. 
  
 Section 8.05. Notice of Defaults. If a default or Event of Default occurs and if it is known to the Trustee, the
Trustee shall give to each Securityholder notice of the default or Event of Default within 90 days after it occurs or, if later, within 15 days after it is known to the Trustee, unless such default or Event of Default shall have been cured or waived
before the giving of such notice. Notwithstanding the preceding sentence, except in the case of a default or Event of Default described in Section 7.01 clauses (a) through (e), the Trustee may withhold the notice if and so long as a
committee of its Responsible Officers in 
  

 58 








 good faith determines that withholding the notice is in the interest of the Securityholders. The preceding sentence shall
be in lieu of the proviso to Section 315(b) of the TIA and such proviso is hereby expressly excluded from this Indenture, as permitted by the TIA. 
  
 Section 8.06. Reports by Trustee to Holders. Within 75 days after each December 31 beginning with December 31, 2005, the Trustee
shall mail to each Securityholder a brief report dated as of such December 31 that complies with TIA Section 313(a), if required by such Section 313(a). The Trustee also shall comply with TIA Section 313(b). Any reports required
by this Section 8.06 shall be transmitted by mail to Securityholders pursuant to TIA Section 313(c). 
  
 A copy of each report at the time of its mailing to Securityholders shall be filed with the SEC and each securities exchange, if any, on which the
Securities are listed. The Company agrees to notify the Trustee promptly whenever the Securities become listed on any securities exchange and of any delisting thereof. 
  
 Section 8.07. Compensation and Indemnity. The Company agrees: 
  
 (a) to pay to the Trustee from time to time such 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 (to the extent permitted by law) 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, advances and disbursements of its agents and
counsel), except any such expense, disbursement or advance as shall be determined to have been caused by its own negligence or willful misconduct; and 
  
 (c) to indemnify the Trustee or any predecessor Trustee and their agents for, and to hold them harmless against, any loss, damage, claim, liability, cost
or expense (including reasonable attorney’s fees and expenses, and taxes (other than taxes based upon, measured by or determined by the income of the Trustee)) incurred without negligence or willful misconduct on its part, arising out of or in
connection with the acceptance or administration of this trust, including the costs and expenses of defending itself against any claim (whether asserted by the Company or any Holder or any other person) or liability in connection with the exercise
or performance of any of its powers or duties hereunder. 
  
 To
secure the Company’s payment obligations in this Section 8.07, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay the principal amount of, or
the Redemption Price, Repurchase Price, Designated Event Repurchase Price, Interest or Additional Interest, if any, as the case may be, on particular Securities. 
  

 59 








 The Company’s payment, reimbursement and indemnity obligations and the lien pursuant to this
Section 8.07 shall survive the satisfaction and discharge of this Indenture, the resignation or removal of the Trustee, and the termination of this Indenture for any reason. In addition to and without prejudice to its rights hereunder, when the
Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 7.01(i) or 7.01(j), the expenses (including the reasonable charges and expenses of its counsel) and the compensation for services are
intended to constitute expenses of administration under any applicable Federal or state bankruptcy, insolvency or similar law. 
  
 For the purposes of this Section 8.07, the “Trustee” shall include any predecessor Trustee; provided, however, that the gross negligence,
negligence, willful misconduct or bad faith of any Trustee hereunder shall not affect the rights of any other Trustee hereunder. 
  
 Section 8.08. Replacement of Trustee. The Trustee may resign at any time by so notifying the Company; provided, however, no such
resignation shall be effective until a successor Trustee has accepted its appointment pursuant to this Section 8.08. The Holders of a majority in aggregate principal amount of the Securities at the time outstanding may remove the Trustee by so
notifying the Trustee and the Company in writing. The Company shall remove the Trustee if: 
  
 (a) the Trustee fails to comply with Section 8.10; 
  
 (b) the Trustee is adjudged bankrupt or insolvent; 
  
 (c) a receiver or public officer takes charge of the Trustee or its property; or 
  
 (d) the Trustee otherwise becomes incapable of acting. 
  
 If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason with respect to the Securities, the Company shall
promptly appoint, by resolution of its Board of Directors, a successor Trustee. 
  
 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company satisfactory in form and substance to the retiring Trustee and the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to
Securityholders. The retiring Trustee shall promptly transfer all property held by it as Trustee for the benefit of the Securities to the successor Trustee, subject to the lien provided for in Section 8.07. 
  
 If a successor Trustee does not take office within 30 days after the retiring
Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of 
  

 60 








 a majority in aggregate principal amount of the Securities at the time outstanding may petition any court of competent
jurisdiction at the expense of the Company for the appointment of a successor Trustee. 
  
 If the Trustee fails to comply with Section 8.10, any Holder of Securities may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

 
 If there are two or more Trustees at any time under this Indenture, each
will be the Trustee of a separate trust held under this Indenture for the benefit of the Securities for which it is acting as Trustee and the rights and obligations of each Trustee will be determined as if it were acting under a separate indenture.

  
 So long as no event which is, or after notice or lapse of
time, or both, would become, an Event of Default shall have occurred and be continuing, if the Company shall have delivered to the Trustee (i) a Board Resolution appointing a successor Trustee, effective as of a date specified therein, and
(ii) an instrument of acceptance of such appointment, effective as of such date, by such successor Trustee in accordance with this Indenture, the Trustee shall be deemed to have resigned as contemplated in this Section 8.08, the successor
Trustee shall be deemed to have been accepted as contemplated in this Indenture, all of such date, and all other provisions of this Indenture shall be applicable to such resignation, appointment and acceptance. 
  
 Section 8.09. Successor Trustee by Merger. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another Person, the resulting, surviving or transferee Person without any further act shall be the successor Trustee, if
such other Person is otherwise eligible hereunder. 
  
 Section 8.10. Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of TIA Sections 310(a)(1) and 310(b). The Trustee (or its parent holding company) shall have a combined capital and surplus of
at least $50,000,000 as set forth in its most recent published annual report of condition. Nothing herein contained shall prevent the Trustee from filing with the SEC the application referred to in the penultimate paragraph of TIA
Section 310(b). 
  
 Section 8.11. Preferential
Collection of Claims Against Company. The Trustee shall comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA
Section 311(a) to the extent indicated therein. 
  

 61 








 ARTICLE 9 
 DISCHARGE OF INDENTURE 
  
 Section 9.01. Discharge of Liability on Securities. When (i) the Company delivers to the Trustee all outstanding Securities (other than
Securities replaced or repaid pursuant to Section 2.07) for cancellation or (ii) all outstanding Securities have become due and payable and the Company deposits with the Trustee cash sufficient to pay all amounts due and owing on all
outstanding Securities (other than Securities replaced pursuant to Section 2.07), and if in either case the Company pays all other sums payable hereunder by the Company, then this Indenture shall, subject to Section 8.07, cease to be of
further effect. The Trustee shall join in the execution of a document prepared by the Company acknowledging satisfaction and discharge of this Indenture on demand of the Company accompanied by an Officers’ Certificate and Opinion of Counsel and
at the cost and expense of the Company. 
  
 Section 9.02.
Repayment to the Company. The Trustee and the Paying Agent shall return to the Company upon written request any money or securities held by them for the payment of any amount with respect to the Securities that remains unclaimed for two years,
subject to applicable abandoned property law. After return to the Company, Holders entitled to the money or securities must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person

 Section 9.03. Application of Trust Money. The Trustee shall hold in trust all money and other consideration
deposited with it pursuant to Section 9.01 and shall apply such deposited money and other consideration through the Paying Agent and in accordance with this Indenture to the payment of amounts due on the Securities. Money and other
consideration so held in trust is subject to the Trustee’s rights under Section 8.07. 
  
 ARTICLE 10

of the Securities. 
  

 63 








 Section 10.02. With Consent of Holders. Except as provided below in this Section 10.02,
this Indenture (including the terms and conditions of the Securities) or the Securities may be amended, modified or supplemented, and noncompliance in any particular instance with any provision of this Indenture or the Securities may be waived, in
each case with the written consent of the Holders of at least a majority of the principal amount of the Securities at the time outstanding. 
  
 Without the written consent or the affirmative vote of each Holder of Securities affected thereby, an amendment, supplement or waiver under this
Section 10.02 may not: 
  
 (a) change the
maturity of any Security, or the payment date of any installment of Interest or Additional Interest payable on any Security;

 (h) modify the provisions of Sections 3.01, 3.02, 3.03,

 (i) reduce the percentage in the aggregate principal amount of the Securities then outstanding required to amend, modify or supplement this Indenture or the Security or waive a prior Event of Default; or 

 

 64 








 (j) reduce the percentage in the aggregate principal amount of the Securities then
outstanding the consent of whose Holders is required for any other waiver provided for in this Indenture. 
  
 It shall not be necessary for the consent of the Holders under this Section 10.02 to approve the particular form of any proposed amendment, but it
shall be sufficient if such consent approves the substance thereof. 
  
 After an amendment under this Section 10.02 becomes effective, the Company shall mail to each Holder a notice briefly describing the amendment. The failure to give such notice to each Holder, or any defect therein, shall not impair or
affect the validity of an amendment under this Section 10.02. 
  
 Nothing in this Section 10.02 shall impair the ability of the Company and the Trustee to amend this Indenture or the Securities without the consent of any Securityholder to provide for the assumption of the Company’s obligations
to the Holders of Securities in the case of a merger, consolidation, conveyance, transfer or lease pursuant to Article 6 hereof; provided that the ability of the Company and the Trustee to amend this Indenture or the Securities is subject to the
requirements set forth in Section 4.10 that no amendment or modification of the provisions of Article 4 shall diminish the rights of the holders of Senior Debt unless such holders shall have agreed in writing thereto. 
  
 Section 10.03. Compliance with Trust Indenture Act. Every
supplemental indenture executed pursuant to this Article shall comply with the TIA as then in effect. 
  
 Section 10.04. Revocation and Effect of Consents; Waivers and Actions. Until an amendment, waiver or other action by Holders becomes
effective, a consent thereto by a Holder of a Security hereunder is a continuing consent by the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same obligation as the consenting Holder’s
Security, even if notation of the consent, waiver or action is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent, waiver or action as to such Holder’s Security or portion of the Security if the
Trustee receives the notice of revocation before the date the amendment, waiver or action becomes effective. After an amendment, waiver or action becomes effective, it shall bind every Holder of such Security. 
  
 Section 10.05. Notice of Amendments; Notation on or Exchange of
Securities. Securities authenticated and delivered after the execution of any supplemental indenture pursuant to this Article may, and shall if required by the Company, bear a notation in form approved by the Company as to any matter provided
for in such supplemental indenture. If the Company shall so determine, new Securities so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any such supplemental indenture may be prepared and executed by the Company
and authenticated and delivered by the Trustee in exchange for outstanding Securities. 
  

 65 








 After any amendment under this Article becomes effective, the Company shall mail to Securityholders a
notice briefly describing such amendment. The failure to give such notice to all Securityholders, or any defect therein, shall not impair or affect the validity of an amendment under this Article. 
  
 Section 10.06. Trustee to Sign Supplemental Indentures. The
Trustee shall sign any supplemental indenture authorized pursuant to this Article 10 if the amendment contained therein does not affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign
such supplemental indenture. In signing such supplemental indenture the Trustee shall receive, and (subject to the provisions of Section 8.01) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel
stating that such supplemental indenture is authorized or permitted by this Indenture. 
  
 Section 10.07. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby. 
  
 ARTICLE 11 
 CONVERSIONS 
  
 Section 11.01.
Conversion Privilege. 
  
 (a) Subject to and upon
compliance with the provisions of this Article 11 (including without limitation the Company’s right, in its sole and absolute discretion, to satisfy its Conversion Obligation in any manner permitted pursuant to Section 11.03), a Holder of
a Security shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Security at any time prior to the close of business on
the Business Day immediately preceding the Stated Maturity at the Conversion Rate (the “Conversion Obligation”) in effect on the date of conversion. 
  
 (b) If the Effective Date or anticipated effective date of a transaction described in clause (3) of the definition of
Change of Control occurs on or prior to April 15, 2009, Holders that surrender their Debentures for conversion at any time from and after the date that is 15 days prior to the date announced by the Company as the anticipated effective date of
such transaction until 15 days after the Effective Date of the transaction or, if such transaction also results in a Designated Event, until the Designated Event Repurchase Date, shall be entitled to receive, in addition to a number of shares of
Common Stock equal to the 
  

 66 








 Conversion Rate per $1,000 principal amount of Securities, subject to the Company’s payment elections as described
in Section 11.03, an additional number of shares of Common Stock (the “Additional Shares”) as described below; provided that if the Stock Price is greater than $70.00 or less than $5.28 (subject in each case to
adjustment as described below), the number of Additional Shares shall be zero. The Company shall notify Holders and a Responsible Officer of the Trustee at the same time the Company publicly announces such transaction (but in no event less than 20
days prior to the anticipated effective date of such transaction) and shall notify the Holders and a Responsible Officer of the Trustee of the actual Effective Date of such transaction within ten days thereof. 
  
 The number of Additional Shares will be determined by reference to the tables
attached as Schedule A hereto, based on the Effective Date of such Change of Control transaction and the Stock Price; provided that if the Stock Price is between two Stock Price amounts in the table or such Effective Date is between two
Effective Dates in such table, the number of Additional Shares will be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Price amounts and the two effective dates, as
applicable, based on a 365-day year. 
  
 The Stock Prices set
forth in the first row of the table in Schedule A hereto will be adjusted as of any date on which the Conversion Rate of the Debentures is adjusted. The adjusted Stock Prices will equal the Stock Prices applicable immediately prior to such
adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of
Additional Shares will be adjusted in the same manner as the Conversion Rate as set forth Section 11.04. 
  
 Notwithstanding the foregoing, in no event will the total number of shares of Common Stock issuable upon conversion exceed 189.3939 per $1,000
principal amount of Securities, subject to adjustments in the same manner as the Conversion Rate as set forth in Section 11.04. 
  
 The Company shall deliver the required Additional Shares to the Holders who elect to convert their Securities on the later of (i) five Business Days
following the Effective Date and (ii) the Conversion Settlement Date for those Securities. 
  
 (c) Notwithstanding the provisions of Section 11.01(b), in the case of a Public Acquirer Change of Control, the Company may, in lieu of increasing
the Conversion Rate by Additional Shares as described in Section 11.01(b), elect to adjust the Conversion Rate as follows. The Conversion Rate on and following the Effective Date of such Public Acquirer Change of Control shall be a number of
shares of Acquirer Common Stock equal to the product of: 
  
 (i) the Conversion Rate in effect immediately prior to the Effective Date of such Public Acquirer Change of Control, times 
  

 67 








 (ii) the average of the quotients obtained, for each Trading Day in the five consecutive
Trading Day period ending on the Trading Day immediately preceding the Effective Date of such Public Acquirer Change of Control (the “Valuation Period”), of: 
  
 (A) the Acquisition Value of the Common Stock on each such Trading Day in the Valuation Period, divided by

  
 (B) the Last Reported Sale Price of the
Acquirer Common Stock on each such Trading Day in the Valuation Period. 
  
 If the Company elects to adjust the Conversion Rate as described in this Section 11.01(c), from and after the Effective Date of such Public Acquirer Change of Control, Holders of the Securities will be entitled to convert their
Securities into a number of shares of Public Acquirer Common Stock based on the Conversion Rate as so adjusted, and Holders will not be entitled to the Additional Shares pursuant to Section 11.03(c) as a result of such Public Acquirer Change of
Control. 
  
 The “Acquisition Value” with respect
to the Common Stock means, for each Trading Day in the Valuation Period with respect to a Public Acquirer Change of Control, the value of the consideration paid per share of Common Stock in connection with such Public Acquirer Change of Control, as
follows: (i) for any cash, 100% of the face amount of such cash; (ii) for any Acquirer Common Stock, 100% of the Last Reported Sale Price of such Acquirer Common Stock on each such Trading Day; and (iii) for any other securities,
assets or property, 100% of the fair market value of such security, asset or property on each such Trading Day, as determined by the Board of Directors. 
  
 A “Public Acquirer Change of Control” means any transaction described under clause (3) of the definition of Change of Control and
the acquirer (or any entity that is a directly or indirectly wholly-owned Subsidiary of the acquirer or of which the acquirer is a directly or indirectly wholly-owned Subsidiary) has a class of common stock traded on a national securities exchange
or quoted on the Nasdaq National Market or which will be so traded or quoted when issued or exchanged in connection with such Change of Control (the “Public Acquirer Common Stock”). 
  
 If the Company elects to adjust the Conversion Rate and the related
Conversion Obligation as described in this Section 11.01(c), the Company, or the acquiring or surviving Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in
force at the date of execution of such supplemental indenture) providing for such adjustment to the Conversion Rate and the Conversion Obligation. Such 
  

 68 








 supplemental indenture shall provide for adjustments that shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article 11. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder of Debentures, at its address appearing on the Security register provided for in
Section 2.03 of this Indenture, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. The Company shall also notify Holders of its election in its notice
to holders pursuant to Section 11.01(b) above. 
  
 Section 11.02. Conversion Procedure; Conversion Rate; Fractional Shares. 
  
 (a) Subject to Section 11.01 and the Company’s rights under Section 11.03, each Security shall be convertible at the office of the Conversion Agent into fully paid and nonassessable shares (calculated
to the nearest 1/100th of a share) of Common Stock. The rate at which Securities shall be convertible (the “Conversion Rate”) shall be initially 151.5151 shares of Common Stock for each $1,000 principal amount of Securities. The
Conversion Rate shall be adjusted in certain instances as provided in Section 11.04 hereof, but shall not be adjusted for any accrued and unpaid Interest or Additional Interest, if any. Upon conversion, no payment shall be made by the Company
with respect to any accrued and unpaid Interest. Instead, such amount shall be deemed paid by the applicable Conversion Settlement Distribution delivered upon conversion of any Security. In addition, no payment or adjustment shall be made in respect
of dividends on the Common Stock with a record date prior to the Conversion Date. Notwithstanding the foregoing, upon conversion a Holder shall receive any accrued and unpaid Additional Interest to the Conversion Date. The Company shall not issue
any fraction of a share of Common Stock in connection with any conversion of Securities, but instead shall, subject to Section 11.04 hereof, make a cash payment (calculated to the nearest cent) equal to such fraction multiplied by the Last
Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Conversion Date. 
  
 (b) Before any Holder of a Security shall be entitled to convert the same into Common Stock, such Holder shall (1) in the case of Global Securities,
comply with the procedures of the Depositary in effect at that time and furnish appropriate endorsement and transfer documents, and (2) in the case of Certificated Securities, surrender such Securities, duly endorsed to the Company or in blank
(and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, and give written notice to the Conversion Agent in the form on the reverse of such Certificated Security (or a facsimile thereof) (a
“Notice of Conversion”) at said office or place that such Holder elects to convert the same and shall state in writing therein the principal amount of Securities to be converted and the name or names (with addresses) in which such
Holder wishes the certificate or certificates for Common Stock included in the Conversion Settlement Distribution, if any, to be registered. 
  

 69 








 Before any such conversion, a Holder also shall pay all taxes or duties, if any, as provided in
Section 11.06 and any amount payable pursuant to Section 11.02(g). 
  
 If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares of Common Stock, if any, that shall be deliverable upon conversion as part of the Conversion
Settlement Distribution shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted thereby) so surrendered. 
  
 (c) A Security shall be deemed to have been converted immediately prior to the close of business on the date (the
“Conversion Date”) that is the date the Holder has complied with Section 11.02(b). A converting Holder shall be deemed to be the holder of record of any Common Stock that is a component of the Conversion Settlement Distribution
as of the later of (i) the Conversion Date, (ii) the expiration of the Cash Settlement Notice Period or (iii) if the Company has elected to deliver cash pursuant to Section 11.03, the final day of the Cash Settlement Averaging
Period. 
  
 (d) Subject to the next succeeding sentence, the
Company will, on the Conversion Settlement Date, (i) pay the cash component (including cash in lieu of any fraction of a share to which such Holder would otherwise be entitled), if any, of the Conversion Settlement Distribution determined
pursuant to Section 11.03 to the Holder of a Security surrendered for conversion, or such Holder’s nominee or nominees, and (ii) issue, or cause to be issued, and deliver to the Conversion Agent or to such Holder, or such
Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the number of full shares of Common Stock, if any, to which such Holder shall be entitled as part of such Conversion Settlement Distribution.

  
 (e) In case any Security shall be surrendered for partial
conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Security so surrendered, without charge to such Holder (subject to the provisions of Section 11.06 hereof), a
new Security or Securities in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Securities. 
  
 (f) By delivering the applicable Conversion Settlement Distribution upon conversion of any Security to the Conversion Agent or to the Holder or such
Holder’s nominee or nominees, the Company will have satisfied in full its Conversion Obligation with respect to such Security, and upon such delivery accrued and unpaid Interest with respect to such Security will be deemed to be paid in full
rather than canceled, extinguished or forfeited. 
  
 (g) If a
Securityholder delivers a Notice of Conversion after the Interest Record Date for a payment of Interest but prior to the corresponding Interest Payment Date, such Securityholder must pay to the Company, at the time such 
  

 70 








 Securityholder surrenders Securities for conversion, an amount equal to the Interest excluding, for the avoidance of
doubt, Additional Interest, if any, that has accrued and will be paid on the related Interest Payment Date. This Section 11.02(g) shall not apply to a Securityholder that converts Securities after an Interest Record Date for a payment of
Interest but on or prior to the corresponding Interest Payment Date if (1) the Company has specified a Redemption Date during such period, (2) the Company has specified a Designated Event Repurchase Date during such period or (3) to
the extent of any overdue Interest, if any overdue Interest exists at the time of conversion with respect to the Securities converted. Notwithstanding the foregoing, the Company shall refund any amount paid by a Securityholder pursuant to this
Section 11.02(g) if the Cash Settlement Notice Period or, if the Company elects to pay cash in lieu of Common Stock pursuant to Section 11.03, the Cash Settlement Averaging Period, ends on or subsequent to the Interest Payment Date
immediately following the date such Securityholder delivered a Notice of Conversion. Such refunded amount shall be paid on the Conversion Settlement Date. 
  
 Section 11.03. Payment of Cash in Lieu of Common Stock. 
  
 (a) If a Holder elects to convert all or any portion of a Security into shares of Common Stock as set forth in
Section 11.01 and the Company receives such Holder’s Notice of Conversion on or prior to the day that is 20 calendar days prior to the Stated Maturity, or with respect to Securities converted in connection with a redemption pursuant to
Section 3.01, the applicable Redemption Date (the “Final Notice Date”), the Company may choose to satisfy all or any portion of its Conversion Obligation in cash. Upon such election, the Company will notify such Holder through
the Trustee of the dollar amount to be satisfied in cash (expressed either as 100% of the Conversion Obligation or as a fixed dollar amount) at any time on or before the date that is three Business Days following the Company’s receipt of the
Notice of Conversion as specified in Section 11.02 (such period, the “Cash Settlement Notice Period”). If the Company elects to pay cash for any portion of the shares otherwise issuable to the Holder, the Holder may retract the
Notice of Conversion at any time during the two Business Day period beginning on the day after the final day of the Cash Settlement Notice Period (the “Conversion Retraction Period”); no such retraction can be made (and a Notice of
Conversion shall be irrevocable) if the Company does not elect to deliver cash in lieu of shares of Common Stock (other than cash in lieu of fractional shares). With respect to any Notice of Conversion received by the Company prior to the Final
Notice Date, the “Conversion Settlement Distribution” for any Security subject to such Notice of Conversion shall consist of cash, Common Stock or a combination thereof, as selected by the Company as set forth below (and any
Additional Shares required to be delivered pursuant to Section 11.01(b) and any accrued and unpaid Additional Interest): 
  
 (i) if the Company elects to satisfy the entire Conversion Obligation in shares of Common Stock, the Conversion Settlement Distribution
shall be a number of shares equal to (1) the aggregate principal amount of the Securities to be converted divided by 1,000, multiplied by (2) the Conversion Rate; 
  

 71 








 (ii) if the Company elects to satisfy the entire Conversion Obligation in cash, the
Conversion Settlement Distribution shall be cash in an amount equal to the product of: 
  
 (A) a number equal to the product of (x) the aggregate principal amount of Securities to be converted divided by 1,000 multiplied by
(y) the Conversion Rate, and 
  
 (B) the
average of the Last Reported Sale Price of the Common Stock for each Trading Day in the Cash Settlement Averaging Period; and 
  
 (iii) if the Company elects to satisfy a fixed portion (other than 100%) of the Conversion Obligation in cash, the Conversion Settlement
Distribution shall consist of such cash amount (“Cash Amount”) and a number of shares equal to the greater of (1) zero and (2) the excess, if any, of the number of shares calculated as set forth in clause (i) above
over the number of shares equal to the sum, for each day of the Cash Settlement Averaging Period, of (x) 10% of the Cash Amount, divided by (y) the Last Reported Sale Price of the Common Stock on such day. 
  
 (b) Prior to any Final Notice Date, the Company will notify the Trustee if it
intends to satisfy all or any portion of the Conversion Obligation with respect to conversions of Securities for which the Company receives a Notice of Conversion after such Final Notice Date in cash and the dollar amount to be satisfied in cash
(expressed either as 100% or a Cash Amount). In such case, such Notice of Conversion will not be retractable and the applicable Conversion Settlement Distribution will be computed in the same manner as set forth in clause (a) above except that
the Cash Settlement Averaging Period shall be the 10 Trading Day period beginning on the Trading Day following the Company’s receipt of the Notice of Conversion. If the Company elects not to satisfy all or any portion of the Conversion
Obligation in cash, then the Conversion Settlement Date will be the first Business Day following the Conversion Date. 
  
 (c) Notwithstanding anything to the contrary in this Indenture, at any time prior to Stated Maturity, the Company may irrevocably elect (the
“Irrevocable Cash Election”), in its sole discretion without the consent of the Holders, by notice to the Trustee and the Holders, to satisfy the Conversion Obligation in cash up to 100% of the principal amount of the Securities
converted after the date of such election, with the remainder of the Conversion Obligation to be satisfied in Common Stock. Settlement amounts shall be computed and settlement dates shall be determined in the same manner as set forth above under
clause (a); provided that (i) the Company will not be required to make any further election or deliver any further notice; (ii) the Notice of Conversion will not be 
  

 72 








 retractable; (iii) the Cash Settlement Averaging Period shall be the 10 Trading Days beginning on the first day
following the Company’s receipt of the Notice of Conversion; and (iv) the Cash Amount shall be the lesser of (A) (x) the then current Conversion Rate multiplied by (y) the average of the Last Reported Sale Prices of the
Common Stock during the Cash Settlement Averaging Period and (B) 100% of the principal amount of a Converted Security. For the avoidance of doubt, following any Irrevocable Cash Election by the Company, there will no longer be a Cash Settlement
Notice Period or a Conversion Retraction Period. 
  
 Section 11.04. Adjustment of Each Conversion Rate. The Conversion Rate shall be adjusted (without duplication) from time to time by the Company as follows: 
  
 (a) In case the Company shall hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock
in shares of Common Stock, each Conversion Rate shall be increased so that the same shall equal the rate determined by dividing such Conversion Rate in effect at the opening of business on the date following the date fixed for the determination of
stockholders entitled to receive such dividend or other distribution by a fraction, 
  
 (i) the numerator of which shall be the number of shares of the Common Stock outstanding at the close of business on the date fixed for
such determination; and 
  
 (ii) the denominator
of which 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 immediately after the opening of business on the day following the date fixed for such determination. If any dividend or distribution of
the type described in this Section 11.04(a) is declared but not so paid or made, each Conversion Rate shall again be adjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

  
 (b) In case the Company shall issue rights or warrants (other
than pursuant to any dividend reinvestment or share purchase plan) to all holders of its outstanding shares of Common Stock entitling them (for a period expiring within 60 days after the date of such issuance) to subscribe for or purchase shares of
Common Stock at a price per share less than the Last Reported Sale Price of the Common Stock on the date fixed for determination of stockholders entitled to receive such rights or warrants, each Conversion Rate shall be adjusted so that the same
shall equal the rate determined by multiplying such Conversion Rate in effect immediately prior to the date fixed for determination of stockholders entitled to receive such rights or warrants by a fraction, 
  

 73 








 (i) the numerator of which shall be the number of shares of Common Stock outstanding on
the date of issuance of such rights or warrants plus the total number of additional shares of Common Stock offered for subscription or purchase, and 
  
 (ii) the denominator of which shall be the number of shares of Common Stock outstanding at the close of business on the date of issuance
of such rights or warrants plus the number of shares that the aggregate offering price of the total number of shares so offered would purchase at such Last Reported Sale Price of the Common Stock. 
  
 Such adjustment shall be successively made whenever any such rights or
warrants are issued, and shall become effective immediately after the opening of business on the day following the date of issuance of such rights or warrants. To the extent that shares of Common Stock are not delivered after the expiration of such
rights or warrants, each Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of
Common Stock actually delivered. In the event that such rights or warrants are not so issued, each Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such date fixed for the determination of
stockholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Last Reported Sale Price of the
Common Stock, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights or warrants and any amount payable on exercise or conversion
thereof, the value of such consideration, if other than cash, to be determined in good faith by the Board of Directors. 
  
 (c) In case outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, each 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 be combined into a smaller number of shares of Common
Stock, each 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 shares of any class of Capital Stock of the
Company, debt securities, assets or rights or warrants to purchase securities of the Company (excluding (x) any dividend or distribution paid exclusively in cash or (y) any dividend, distribution or issuance referred to in
Section 11.04(a) or (b)) (any of 
  

 74 








 the foregoing hereinafter in this Section 10.04(d) called the “Distributed Assets”), then, in each
such case, each Conversion Rate shall be adjusted so that the same shall be equal to the rate determined by multiplying such Conversion Rate in effect on the Record Date with respect to such distribution by a fraction, 
  
 (i) the numerator of which shall be the Current Market Price
per share of the Common Stock on such Record Date; and 
  
 (ii) the denominator of which shall be the Current Market Price per share of the Common Stock on the Record Date minus the Fair Market Value, as determined in good faith by the Board of Directors, of the Distributed Assets applicable to one
share of Common Stock, 
  
 such adjustment to become effective immediately prior
to the opening of business on the day following such Record Date; provided, however, that in the event (1) the then Fair Market Value (as so determined) of the portion of the Distributed Assets so distributed applicable to one share of
Common Stock is equal to or greater than the Current Market Price of the Common Stock on the Record Date or (2) the Current Market Price of the Common Stock on the Record Date exceeds the then Fair Market Value (as so determined) of the portion
of the Distributed Assets so distributed applicable to one share of Common Stock by less than $1.00, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive upon conversion the amount
of Distributed Assets such holder would have received had such holder converted each Security on the Record Date assuming the Company did not elect to deliver cash upon conversion pursuant to Section 11.03. In the event that such dividend or
distribution is not so paid or made, each Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
  
 Rights or warrants distributed by the Company to all holders of Common Stock
entitling the holders thereof to subscribe for or purchase shares of the Company’s Capital Stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger
Event”): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for
purposes of this Section 11.04 (and no adjustment to each Conversion Rate under this Section 11.04 will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been
distributed and an appropriate adjustment (if any is required) to each Conversion Rate shall be made under this Section 11.04(d). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this
Indenture, are subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall
be deemed to be the date of distribution and record date with respect to new rights or 
  

 75 








 warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of
the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for
purposes of calculating a distribution amount for which an adjustment to each Conversion Rate under this Section 11.04 was made, (1) in the case of any such rights or warrants that shall all have been redeemed or repurchased without
exercise by any holders thereof, each Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per
share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such
redemption or repurchase, and (2) in the case of such rights or warrants that shall have expired or been terminated without exercise by any holders thereof, each Conversion Rate shall be readjusted as if such rights and warrants had not been
issued. 
  
 For purposes of this Section 11.04(d) and
Sections 11.04(a) and (b), any dividend or distribution to which this Section 11.04(d) is applicable that also includes shares of Common Stock, or rights or warrants to subscribe for or purchase shares of Common Stock (or both), shall be deemed
instead to be (1) a dividend or distribution of debt securities, assets or shares of capital stock other than such shares of Common Stock or rights or warrants (and any Conversion Rate adjustment required by this Section 11.04(d) with
respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights or warrants (and any further Conversion Rate adjustment required by Sections
11.04(a) and (b) with respect to such dividend or distribution shall then be made), except (A) the Record Date of such dividend or distribution shall be substituted as “the date fixed for the determination of stockholders entitled to
receive such dividend or other distribution”, “the date fixed for the determination of stockholders entitled to receive such rights or warrants” and “the date fixed for such determination” within the meaning of Sections
11.04(a) and (b), and (B) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding at the close of business on the date fixed for such determination” within the meaning of
Section 11.04(a). 
  
 If any Distributed Assets requiring any
adjustment pursuant to this Section 11.04(d) consists of the Capital Stock of, or similar equity interests in, a Subsidiary or other business unit of the Company, each Conversion Rate in effect immediately before the close of business on the
Record Date fixed for determination of shareholders entitled to receive the distribution shall instead be increased by multiplying such Conversion Rate then in effect by a fraction, (A) the numerator of which is the sum of (1) the average
of the Last Reported Sale Prices of such distributed security for the 10 Trading Days commencing on and 
  

 76 








 including the fifth Trading Day after the Ex-Dividend Date on the NYSE or such other national or regional exchange or
market on which the securities are then listed or quoted, plus (2) the average of the Last Reported Sale Prices of the Common Stock over the same Trading Day period and (B) the denominator of which is such average of the Last Reported Sale
Prices of the Common Stock. 
  
 (e) In case the Company shall, by
dividend or otherwise, distribute to all holders of its Common Stock cash (an “Extraordinary Cash Dividend”) (excluding any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company,
whether voluntary or involuntary), then, in such case, each Conversion Rate shall be adjusted so that the same shall equal the rate determined by multiplying such Conversion Rate in effect immediately prior to the close of business on the Record
Date for such Extraordinary Cash Dividend by a fraction, 
  
 (i) the numerator of which shall be the Current Market Price of the Common Stock on such Record Date, and 
  
 (ii) the denominator of which shall be such Current Market Price of the Common Stock minus the amount of cash so distributed applicable to
one share of Common Stock, 
  
 such adjustment to be effective immediately prior
to the opening of business on the day following the Record Date; provided, however, that in the event the portion of cash so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price of the
Common Stock on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive upon conversion the amount of cash such holder would have received had such holder converted
each Security on the Record Date assuming the Company did not elect to deliver cash upon conversion pursuant to Section 11.03. In the event that such dividend or distribution is not so paid or made, each Conversion Rate shall again be adjusted
to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
  
 (f) In case a tender or exchange offer made by the Company or any Subsidiary for all or any portion of the Common Stock shall expire and such tender or
exchange offer (as amended upon the expiration thereof) shall require the payment to stockholders of consideration per share of Common Stock having a Fair Market Value (as determined in good faith by the Board of Directors) that as of the last time
(the “Expiration Time”) tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended) exceeds the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the Expiration
Time, each Conversion Rate shall be adjusted so that the same shall equal the rate determined by multiplying such Conversion Rate in effect immediately prior to the Expiration Time by a fraction 
  

 77 








 (i) the numerator of which shall be the sum of (x) the Fair Market Value (determined
in good faith by the Board of Directors) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not
withdrawn as of the Expiration Time (the shares deemed so accepted up to any such maximum, being referred to as the “Purchased Shares”) and (y) the product of the number of shares of Common Stock outstanding (less any Purchased
Shares) at the Expiration Time and the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the Expiration Time, and 
  
 (ii) the denominator of which shall be the number of shares of Common Stock outstanding (including any Purchased Shares) at the Expiration
Time multiplied by Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the Expiration Time, 
  
 such adjustment to become effective immediately prior to the opening of business on the day following the Expiration Time. In the event that the Company is obligated to
purchase shares pursuant to any such tender or exchange offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, each Conversion Rate shall again be adjusted to be the
Conversion Rate that would then be in effect if such tender or exchange offer had not been made. 
  
 (g) In the event that a Person other than the Company or a Subsidiary of the Company makes a payment in respect of a tender offer or exchange offer with
respect to which, as of the last time (the “Offer Expiration Time”), tenders or exchanges may be made pursuant to such offer, the Board of Directors is not recommending rejection of the offer, each Conversion Rate will be increased
by multiplying such Conversion Rate in effect immediately prior to the Offer Expiration Time by a fraction: 
  
 (i) the numerator of which shall be the sum of (x) the Fair Market Value, as determined in good faith by the Board of Directors, of
the aggregate consideration payable to the Company’s stockholders based on the acceptance of (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the
Offer Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the “Accepted Purchased Shares”) and (y) the product of the number of shares of the Company’s Common Stock outstanding less
any such Purchased Shares and the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the Expiration Time, and 
  
 (ii) the denominator of which will be the product of the number of shares of Common Stock outstanding, including any such Purchased
Shares, and the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the Offer Expiration Time. 
  

 78 








 The adjustment referred to in this Section 11.04(g) will be made only if (x) the tender offer
or exchange offer is for an amount that increases the offeror’s ownership of Common Stock to more than 25% of the total shares of Common Stock outstanding; and (y) the cash and value of any other consideration included in the payment per
share of Common Stock exceeds the Last Reported Sale Price per share of Common Stock on the Trading Day next succeeding the Offer Expiration Time; provided that, the adjustment referred to in this Section 11.04(g) will not be made if, as
of the Offer Expiration Time, the offering documents for such tender or exchange offer disclose a plan or an intention to cause the Company to engage in a consolidation or merger or a sale of all or substantially all of the Company’s assets.

  
 (h) The Company, from time to time, may, to the extent
permitted by applicable law and the listing requirements of the NYSE (and any other exchange on which shares of the Common Stock are then listed), make such increases in the Conversion Rate, in addition to those required by this Section 11.04
as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase shares of Common Stock resulting from any dividend or distribution of Capital Stock (or rights to acquire stock)
or from any event treated as such for income tax purposes. 
  
 To
the extent permitted by applicable law and the listing requirements of the NYSE (and any other exchange on which shares of Common Stock are then listed), 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) Business 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. Whenever the
Conversion Rate is increased pursuant to the preceding sentence, the Company shall mail to holders of record of the Securities a notice of the increase 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. 
  
 (i) All calculations under this Article 11 shall be made by the Company and shall be made to the nearest cent or to the nearest one-ten thousandth of a
share, as the case may be, with one half-cent and 0.00005 of a share, respectively, being rounded upward. No adjustment need be made for: 
  
 (i) the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or
interest payable on securities of the Company and the investment of additional optional amounts in shares of Common Stock under any plan, 
  

 79 








 (ii) the issuance of any shares of Common Stock or options or rights to purchase those
shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries, 
  
 (iii) the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible
security not described in clause (ii) above and outstanding as of the date the Securities were first issued, 
  
 (iv) a change in the par value of the Common Stock, 
  
 (v) the issuance of any shares of Common Stock pursuant to conversion of the Securities, or 
  
 (vi) accrued and unpaid Interest, including Additional
Interest, if any. 
  
 To the extent the Securities become
convertible into cash, assets, property or securities (other than Capital Stock of the Company), no adjustment need be made thereafter as to such cash, assets, property or securities. 
  
 (j) Whenever each Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any
Conversion Agent other than the Trustee an Officers’ Certificate setting forth each Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the
Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of each Conversion Rate and may assume that the last Conversion Rates of which it has knowledge are still in effect.
Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of each Conversion Rate setting forth each adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail such notice
of such adjustment of each Conversion Rate to the holder of each Security at his last address appearing on the Security register provided for in Section 2.03 of this Indenture, within twenty (20) days after execution thereof. Failure to
deliver such notice shall not affect the legality or validity of any such adjustment. 
  
 (k) In any case in which this Section 11.04 provides that an adjustment shall become effective immediately after (1) a record date or Record Date for an event, (2) the date fixed for the determination
of stockholders entitled to receive a dividend or distribution pursuant to Section 11.04(a), (3) a date fixed for the determination of stockholders entitled to receive rights or warrants pursuant to Section 11.04(b), (4) the
Expiration Time for any tender or exchange offer pursuant to Section 11.04(f) or (5) the Offer Expiration Time for any tender or exchange offer pursuant to Section 11.04(g) (each a “Determination Date”), the Company
may elect to defer until the occurrence of the relevant Adjustment 
  

 80 








 Event (as hereinafter defined) (x) issuing to the holder of any Security converted after such Determination Date and
before the occurrence of such Adjustment Event, the additional shares of Common Stock or other securities issuable upon such conversion by reason of the adjustment required by such Adjustment Event over and above the Common Stock issuable upon such
conversion before giving effect to such adjustment and (y) paying to such holder any amount in cash in lieu of any fraction pursuant to Section 11.02(a). For purposes of this Section 11.04(k), the term “Adjustment
Event” shall mean: 
  
 (i) in any case
referred to in clause (1) hereof, the occurrence of such event, 
  
 (ii) in any case referred to in clause (2) hereof, the date any such dividend or distribution is paid or made, 
  
 (iii) in any case referred to in clause (3) hereof, the date of expiration of such rights or warrants, and 
  
 (iv) in any case referred to in clause (4) or
(5) hereof, the date a sale or exchange of Common Stock pursuant to such tender or exchange offer is consummated and becomes irrevocable. 
  
 (l) For purposes of this Section 11.04, 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. 
  
 (m) If rights or warrants for which an adjustment
has been made pursuant to the provisions of this Section 11.04 expire unexercised, the Conversion Rate shall be readjusted as if such unexercised rights or warrants had not been issued. 
  
 Section 11.05. Effect of Reclassification; Consolidation; Merger or
Sale. If any of the following events occur, namely (a) any reclassification or change of the outstanding shares of Common Stock (other than a subdivision or combination to which Section 11.04(c) applies), (b) any consolidation,
merger, binding share exchange or combination of the Company with another Person as a result of which holders of Common Stock shall be entitled to receive stock, other securities or other property or assets (including cash) with respect to or in
exchange for such Common Stock, or (c) any sale or conveyance of all or substantially all the properties and assets of the Company to any other Person as a result of which holders of Common Stock shall be entitled to receive stock, other
securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, then the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which
shall 
  

 81 








 comply with the TIA as in force at the date of execution of such supplemental indenture) providing that each $1,000
principal amount of Securities shall be convertible, subject to the provisions of Section 11.03, based on the applicable Conversion Rate and the kind and amount of shares of stock, other securities or other property or assets (including cash)
receivable upon such reclassification, change, consolidation, merger, binding share exchange, combination, sale or conveyance by a holder of one share of Common Stock in such transaction (the “Exchange Property”) assuming such
holder of Common Stock did not exercise his rights of election, if any, as to the kind or amount of stock, other securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger,
combination, sale or conveyance (provided that, if the kind or amount of stock, other securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, statutory share exchange,
combination, sale or conveyance is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised (“nonelecting share”), then for the purposes of this Section 11.05 the
kind and amount of stock, other securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, statutory share exchange, combination, sale or conveyance for each nonelecting share shall
be deemed to be the kind and amount so receivable per share by a plurality of the nonelecting shares). After the effective date of any such reclassification, change, consolidation, merger, statutory share exchange, combination, sale or conveyance,
the Conversion Obligation in respect of any Securities surrendered for conversion shall be satisfied in Exchange Property. Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article 11. 
  
 The Company shall
cause notice of the execution of such supplemental indenture to be mailed to each holder of Securities, at its address appearing on the Security register provided for in Section 2.03 of this Indenture, within twenty (20) days after
execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. 
  
 The above provisions of this Section shall similarly apply to successive reclassifications, changes, consolidations, mergers, statutory share exchanges,
combinations, sales and conveyances. 
  
 If this
Section 11.05 applies to any event or occurrence, Section 11.04 shall not apply. 
  
 Section 11.06. Taxes on Shares Issued. The issue of stock certificates on conversions of Securities shall be made without charge to the converting Holder for any tax in respect of the issue thereof. The
Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the holder of any Securities converted, and the Company shall not be
required to issue or deliver 
  

 82 








 any such stock certificate unless and until the Person or Persons requesting the issue thereof shall have paid to the
Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. 
  
 Section 11.07. Reservation of Shares, Shares to be Fully Paid; Compliance with Governmental Requirements; Listing of Common Stock. 

  
 (a) The Company shall provide, free from preemptive rights,
out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for the conversion of the Securities from time to time as such Securities are presented for conversion, assuming the Company does not
elect to deliver cash upon conversion pursuant to Section 11.03. 
  
 (b) Before taking any action which would cause an adjustment increasing any Conversion Rate to an amount that would cause either Conversion Price to be reduced below the then par value, if any, of the shares of Common Stock issuable upon
conversion of the Securities, the Company will take all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue shares of such Common Stock at such adjusted Conversion Rate.

  
 (c) (i) The Company covenants that all shares of Common
Stock which may be issued upon conversion of Securities will upon issue be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. 
  
 (ii) The Company covenants that, if any shares of Common
Stock to be provided for the purpose of conversion of Securities hereunder require registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company will
in good faith and as expeditiously as possible, to the extent then permitted by the rules and interpretations of the Securities and Exchange Commission (or any successor thereto), endeavor to secure such registration or approval, as the case may be.

  
 (iii) The Company further covenants that, if
at any time the Common Stock shall be listed on the NYSE or any other national securities exchange or automated quotation system, the Company will, if permitted by the rules of such exchange or automated quotation system, list and keep listed, so
long as the Common Stock shall be so listed on such exchange or automated quotation system, all Common Stock issuable upon conversion of the Securities; provided, however, that, if the rules of such exchange or automated quotation system
permit the Company to defer the listing of such Common Stock until the first conversion of the Securities into Common Stock in accordance with the provisions of this Indenture, the Company covenants to list such Common Stock issuable upon conversion
of the Securities in accordance with the requirements of such exchange or automated quotation system at such time.

 Section 11.08. Responsibility of Trustee. The Trustee and any other Conversion Agent shall
not at any time be under any duty or responsibility to any holder of Securities to determine any Conversion Rate or whether any facts exist which may require any adjustment of each Conversion Rate, or with respect to the nature or extent or
calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with
respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or property, which may at any time be issued or delivered upon the conversion of any Security; and the Trustee and any other Conversion
Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities
or property or cash upon the surrender of any Security for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 11. Without limiting the generality of the foregoing,
neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 11.05 relating either to the kind or amount
of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Securities after any event referred to in such Section 11.05 or to any adjustment to be made with respect thereto, but, subject to
the provisions of Section 8.01, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee
prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by Section 11.01 has occurred that makes the
Securities eligible for conversion until the Company has delivered to the Trustee and the Conversion Agent an Officer’s Certificate stating that such event has occurred, on which Certificate the Trustee may conclusively rely, and the Company
agrees to deliver such Officer’s Certificate to the Trustee and the Conversion Agent as promptly as practicable after the occurrence of any such event. 
  
 Section 11.09. Notice to Holders Prior to Certain Actions. In case: 
  
 (a) the Company shall declare a dividend (or any other distribution) on its Common Stock that would require
an adjustment in each Conversion Rate pursuant to Section 11.04; or 
  
 (b) the Company shall authorize the granting to the holders of all or substantially all of its Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants; or

  

 84 








 (c) of any reclassification or reorganization of the Common Stock of the Company (other
than a subdivision or combination of its outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation, merger or statutory share exchange to which the Company is a
party and for which approval of any stockholders of the Company is required, or of the sale or transfer of all or substantially all of the assets of the Company; or 
  
 (d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; 
  
 the Company shall cause to be filed with the Trustee and to be mailed to each Holder of
Securities at his address appearing on the register provided for in Section 2.03 of this Indenture, as promptly as possible but in any event at least ten (10) days prior to the applicable date hereinafter specified, a notice stating
(x) the date on which a record is to be taken for the purpose of such dividend, distribution of rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend,
distribution or rights are to be determined, or (y) the date on which such reclassification, consolidation, merger, or statutory share exchange, sale, transfer, dissolution, liquidation or winding up is expected to become effective or occur,
and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, or statutory share
exchange, sale, transfer, dissolution, liquidation or winding up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such dividend, distribution, reclassification, consolidation, merger, or statutory
share exchange, sale, transfer, dissolution, liquidation or winding up. 
  
 Section 11.10. Rights Issued in Respect of Common Stock Issued upon Conversion. To the extent the Company has a rights plan that is in effect upon a Conversion Date, Holders of Securities shall receive, upon conversion of
Securities, in addition to shares of Common Stock, cash, or combination of cash and shares of Common Stock, the rights under the applicable rights plan unless, prior to the Conversion Date, the rights have separated from the Common Stock, in which
case the Conversion Rate in effect shall be adjusted at the time of separation as if the Company had distributed to all holders of Common Stock the assets, debt securities, shares of Capital Stock or rights or warrants to purchase securities of the
Company as described in Section 11.04(d). 
  
 Section 11.11. Unconditional Rights of Holders to Convert. Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to convert its Security in

  

 85 








 accordance with this Article 11 and to bring an action for the enforcement of any such right to convert, and such rights
shall not be impaired or affected without the consent of such Holder.

 [FORM OF REVERSE OF CONVERTIBLE SENIOR SUBORDINATED DEBENTURES IN GLOBAL FORM] 
  
 5.00% Convertible Senior Subordinated Debentures Due 2025 
  
 This Security is one of a duly authorized issue of 5.00% Convertible Senior
Subordinated Debentures Due 2025 (the “Securities”) of BearingPoint, Inc., a Delaware corporation (including any successor corporation under the Indenture hereinafter referred to, the “Company”), issued under an
Indenture, dated as of April 27, 2005 (the “Indenture”), between the Company and The Bank of New York, as trustee (the “Trustee”). The terms of the Security include those stated in the Indenture, those made
part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (“TIA”), and those set forth in this Security. This Security is subject to all such terms, and Holders are referred to the Indenture and the TIA for a
statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Security and the terms of the Indenture, the terms of the Indenture shall control. Capitalized terms used but not
defined herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 
  
 1. Interest. 
  
 The Debentures shall bear interest on the principal amount thereof at a rate of 5.00% per year. The Company shall pay Additional Interest as set
forth in Section 5.07 of the Indenture and the Registration Rights Agreement. 
  
 Interest will be payable semi-annually on each Interest Payment Date to Holders at the close of business on the preceding Interest Record Date. Interest will be computed on the basis of a 360-day year comprised of
twelve 30 day months. 
  
 If any Interest Payment Date, Stated
Maturity date, Redemption Date, Repurchase Date or Designated Event Repurchase Date of a Security falls on a day that is not a Business Day, the required payment of Interest, if any, and principal will be made on the next succeeding Business Day and
no Interest on such payment will accrue for the period from and after the Interest Payment Date, the Stated Maturity date, Redemption Date, Repurchase Date or Designated Event Repurchase Date to such next succeeding Business Day. 
  
 If the principal amount of any Security, or any accrued and unpaid Interest
or Additional Interest, if any, are not paid when due (whether upon acceleration pursuant to Section 7.02 of the Indenture, upon the date set for payment of the Redemption Price, upon the date set for payment of the Repurchase Price or
Designated Event Repurchase Price, upon the Stated Maturity of the Securities, upon the Interest Payment Dates or upon the Additional Interest Payment Dates as defined in the Registration Rights Agreement), then in each such case the overdue amount
shall, to the extent permitted by law, bear cash interest at a rate per annum that is 1% higher than the interest rate set forth on the face of this Security, compounded semiannually, which interest shall accrue 
  

 A-5 








 from the date such overdue amount was originally due to the date payment of such amount, including interest thereon, has
been made or duly provided for. All such interest shall be payable in cash on demand but if not so demanded shall be paid quarterly to the Holders on the last day of each quarter. 
  
 2. Method of Payment. 
  
 Except as provided below, the Company shall pay Interest on (i) Global Securities, to DTC in immediately available funds, (ii) any Certificated
Security having an aggregate principal amount of $5,000,000 or less, by check mailed to the Holder of such Security and (iii) any Certificated Security having an aggregate principal amount of more than $5,000,000, by wire transfer in
immediately available funds or by mail at the election of the Holder of any such Security. 
  
 At Stated Maturity, the Company will pay Interest and principal on Certificated Securities at the Company’s office or agency in The City of New York and will pay principal on Global Securities to DTC in
immediately available funds. 
  
 Subject to the terms and
conditions of the Indenture, the Company will make payments in cash in respect of Redemption Prices, Repurchase Prices, Designated Event Repurchase Prices and at Stated Maturity to Holders who surrender Securities to a Paying Agent to collect such
payments in respect of the Securities. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. However, the Company may make such cash payments by check
payable in such money. 
  
 3. Indenture. 
  
 The Securities are subordinated unsecured obligations of the Company. The
Indenture does not limit other indebtedness of the Company, secured or unsecured. 
  
 4. Redemption at the Option of the Company. 
  
 No sinking fund is provided for the Securities. The Debentures are redeemable for cash at the option of the Company, in whole or in part, at any time or from time to time on or after April 15, 2009 upon not less than 30 nor more than
60 days’ notice by mail for a redemption price equal to 100% of the principal amount of the Debentures redeemed plus accrued and unpaid Interest and Additional Interest, if any, on those Securities to (but excluding) the Redemption Date (the
“Redemption Price”). 
  
 In no event will any
Debenture be redeemable before April 15, 2009. 
  
 5. Purchase By the
Company at the Option of the Holder. 
  
 Subject to the terms
and conditions of the Indenture, the Company shall become obligated to purchase, at the option of the Holder, all or any portion of the Debentures held by such Holder on April 15, 2009, April 15, 2013, April 15, 2015 and
April 15, 2020, in integral multiples of $1,000 at a Repurchase Price equal to the principal 
  

 A-6 








 amount of those Securities plus accrued and unpaid Interest, and Additional Interest, if any, on those Securities up to
(but excluding) the Repurchase Date. To exercise such right, a Holder shall deliver to the Paying Agent a Purchase Notice containing the information set forth in the Indenture, at any time from the opening of business on the date that is 20 Business
Days prior to such Repurchase Date until the close of business on such Repurchase Date, and shall deliver the Securities to the Paying Agent as set forth in the Indenture. 
  
 At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to
purchase the Securities held by such Holder after the occurrence of a Designated Event for a Designated Event Repurchase Price equal to the principal amount of those Securities plus accrued and unpaid Interest and Additional Interest, if any, on
those Securities up to (but excluding) the Designated Event Repurchase Date. 
  
 Holders have the right to withdraw any Repurchase Notice or Designated Event Repurchase Notice, as the case may be, by delivering to the Paying Agent a written notice of withdrawal in accordance with the provisions of
the Indenture. 
  
 If cash sufficient to pay the Repurchase Price
or Designated Event Repurchase Price, as the case may be, of all Securities or portions thereof to be purchased as of the Repurchase Date or the Designated Event Repurchase Date, as the case may be, is deposited with the Paying Agent, on the
Business Day immediately following the Repurchase Date or the Designated Event Repurchase Date, Interest and Additional Interest, if any, will cease to accrue on such Securities (or portions thereof) on and following such Repurchase Date or
Designated Event Repurchase Date, and the Holder thereof shall have no other rights as such other than the right to receive the Repurchase Price or Designated Event Repurchase Price upon surrender of such Security. 
  
 6. Reserved. 
  
 7. Conversion. 
  
 Subject to and in compliance with the provisions of the Indenture, a Holder is entitled, at such Holder’s option, to convert the Holder’s
Security (or any portion of the principal amount thereof that is $1,000 or an integral multiple $1,000), into fully paid and nonassessable shares of Common Stock at the Conversion Rate in effect at the time of conversion; provided, however,
the Company may satisfy its obligation with respect to any demand for conversion by delivering Common Stock, cash or a combination of cash and Common Stock as set forth in the Indenture. 
  
 A Security in respect of which a Holder has delivered a Purchase Notice or Designated Event Repurchase Notice, as the case
may be, exercising the option of such Holder to require the Company to purchase such Security may be converted only if such Repurchase Notice or Designated Event Repurchase Notice, as the case may be, is withdrawn in accordance with the terms of the
Indenture. 
  

 A-7 








 The initial Conversion Rate for the Debentures is 151.5151 shares of Common Stock per $1,000 principal
amount, subject to adjustment in certain events described in the Indenture. The Conversion Rate shall not be adjusted for any accrued and unpaid Interest or accrued and unpaid Additional Interest. Upon conversion, no payment shall be made by the
Company with respect to accrued and unpaid Interest. Instead, such amount shall be deemed paid by the shares of Common Stock delivered upon conversion of any Security. A Holder shall receive, however, accrued and unpaid Additional Interest, if any.

  
 In certain circumstances as set forth in the Indenture, a
Holder shall receive Additional Shares as set forth in Section 11.01 of the Indenture. 
  
 8. Paying Agent, Conversion Agent and Registrar. 
  
 Initially, the Trustee will act as Paying Agent, Conversion Agent and Registrar. The Company may appoint and change any Paying Agent, Conversion Agent or Registrar without notice, other than notice to the Trustee;
provided that the Company will maintain at least one Paying Agent in the City of New York, which shall initially be an office or agency of the Trustee. The Company or any of its Subsidiaries or any of their Affiliates may act as Paying Agent,
Conversion Agent or Registrar. 
  
 9. Denominations; Transfer; Exchange.

  
 The Securities are in fully registered form, without
coupons, in denominations of $1,000 of principal amount and integral multiples of $1,000. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not transfer or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in
part, the portion of the Security not to be redeemed) or any Securities in respect of which a Purchase Notice or Designated Event Repurchase Notice has been given and not withdrawn (except, in the case of a Security to be purchased in part, the
portion of the Security not to be purchased) or any Securities for a period of 15 days before the mailing of a notice of redemption of Securities to be redeemed. 
  
 10. Persons Deemed Owners. 
  
 The registered Holder of this Security may be treated as the owner of this Security for all purposes. 
  
 11. Unclaimed Money or Securities. 
  
 As set forth in the Indenture and subject to applicable abandoned property
laws, the Trustee and the Paying Agent shall return to the Company upon written request any money or securities held by them for the payment of any amount with respect to the Securities that remains unclaimed for two years, subject to applicable
unclaimed 
  

 A-8 








 property law. After return to the Company, Holders entitled to the money or securities must look to the Company for
payment as general creditors unless an applicable abandoned property law designates another person. 
  
 12. Amendment; Waiver. 
  
 Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended with the written consent of the Holders of at least a majority in aggregate principal amount of the outstanding Securities and
(ii) certain Events of Defaults may be waived with the written consent of the Holders of a majority in aggregate principal amount of the outstanding Securities. Subject to terms set forth in the Indenture, without the consent of any
