Holder affected by such event, at such Holder’s address as it appears in the Security Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. In any case
where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be
filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. 
  
 In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then
such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. 
  
 Whenever under this Indenture the Trustee is required to provide any notice by mail, in all cases the Trustee may alternatively provide notice by
overnight courier or by telefacsimile, with confirmation of transmission. 
  
 Section 1.07. Conflict with Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under such Act to be a part of and govern
this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the 
  

 13 








 
latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be. 
  
 Section 1.08. Effect of Headings and Table of Contents. The Article
and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. 
  
 Section 1.09. Successors and Assigns. All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether
so expressed or not. 
  
 Section 1.10. Separability Clause.
In case any provision in this Indenture or in the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
  
 Section 1.11. Benefits of Indenture. Nothing in this Indenture or in
the Securities, express or implied, shall give to any Person, other than the parties hereto and their respective successors hereunder and the Holders of Securities, any benefit or any legal or equitable right, remedy or claim under this Indenture.

  
 Section 1.12. Governing Law. This Indenture and the
Securities shall be governed by and construed in accordance with the laws of the State of New York. 
  
 Section 1.13. Legal Holiday. In any case where any Interest Payment Date or Stated Maturity of any Security shall not be a Business Day, then
(notwithstanding any other provision of this Indenture or of the Securities) payment of interest or principal need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the
Interest Payment Date or at the Stated Maturity, provided that no interest shall accrue with respect to such payment for the period from and after such Interest Payment Date or Stated Maturity, as the case may be.

 Section 2.03 Form of Reverse of Security. This Security is one of a duly authorized issue of
Securities of the Company, designated as its 3.0% Senior Convertible Notes Due 2023 (the “Securities”), all issued or to be issued under and pursuant to an Indenture dated as of June 11, 2003 (the “Indenture”),
between the Company and the J.P. Morgan Trust Company, National Association (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights,
obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities. 
  
 The indebtedness evidenced by the Securities is unsecured and unsubordinated indebtedness of the Company and ranks equally with the Company’s other
unsecured and unsubordinated indebtedness. 
  
 Redemption at
the Option of the Company. No sinking fund is provided for the Securities. The Securities are redeemable as a whole, or from time to time in part, at any time commencing on June 8, 2010 at the option of the Company at the redemption price (the
“Redemption Price”) equal to 100%, expressed as a percentage of Principal Amount for Securities redeemed, together with accrued and unpaid interest and Additional Amounts, if any, to, but excluding, the Redemption Date. 

 
 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, the Securities held by such Holder on each of the Purchase Dates of June 1, 2010 and June 1, 2018, at 100% of the Principal Amount,
plus accrued and unpaid interest and Additional Amounts, if any, to, but excluding, the Purchase Date (the “Purchase Price”), upon delivery of a Purchase Notice containing the information set forth in the Indenture, at any time from
the opening of business on the date that is 25 days prior to such Purchase Date until the close of business on the date that is 1 Business Day prior to such Purchase Date and upon delivery of the Securities to the Paying Agent by the Holder as set
forth in the Indenture. The Purchase Price will be paid in cash. 
  
 At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to repurchase the Securities if a Fundamental Change occurs at any time prior to the Stated Maturity at 100% of the
Principal Amount plus accrued and unpaid interest and Additional Amounts, if any, to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), which Fundamental Change Repurchase Price shall
be paid in cash. However, notwithstanding the foregoing, a Holder will not have the right to require the Company to repurchase the Securities if the Sale Price per share of the Company’s Common Stock for any 
  

 19 








 
five Trading Days within the period of 10 consecutive Trading Days ending immediately after the later of the Fundamental Change or the public announcement of
the Fundamental Change equals or exceeds 105% of the Conversion Price of the Securities in effect on each of those five Trading Days. 
  
 Holders have the right to withdraw any Purchase Notice or Fundamental Change 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 Purchase Price or Fundamental Change Repurchase Price, as the case may be, of all Securities or portions thereof to be purchased on a Purchase Date or on a Fundamental Change Repurchase
Date, as the case may be, is deposited with the Paying Agent on the Business Day following the Purchase Date or the Fundamental Change Repurchase Date, as the case may be, such Securities will cease to be outstanding and interest, including
Additional Amounts, if any, will cease to accrue on such Securities (or portions thereof) immediately after such Purchase Date or Fundamental Change Repurchase Date, as the case may be, and the Holder thereof shall have no other rights as such
(other than the right to receive the Purchase Price or Fundamental Change Repurchase Price, as the case may be, upon surrender of such Security). 
  
 Conversion. Subject to the provisions of the Indenture (including without limitation the conditions to conversion described more fully below set
forth in Section 13.01 of the Indenture), a Holder may convert each of its Securities into shares of the Company’s common stock at an initial conversion price of approximately $44.38 per share of common stock (the “Conversion
Price”), at any time prior to the close of business on June 1, 2023. The Conversion Price in effect at any given time is subject to adjustment. A Holder may convert fewer than all of such Holder’s Securities so long as the Securities
converted are an integral multiple of $1,000 principal amount. Subject to the Company’s right to deliver cash or a combination of cash and shares of its Common Stock upon conversion of the Securities, Holders will not receive any cash payment
representing accrued and unpaid interest upon conversion of a Security. Accrued and unpaid interest and any Additional Amounts will be deemed paid in full rather than canceled, extinguished or forfeited. 
  
 Holders may surrender their Securities for conversion, in whole or in part,
into shares of the Company’s Common Stock prior to maturity, redemption or repurchases under the following circumstances (in each case, as more fully described in the Indenture): (A) if during any fiscal quarter (beginning with the fourth
fiscal quarter of 2003) the closing Sale Price of the Company’s Common Stock for at least 20 Trading days in the 30 Trading Day period ending on the last Trading Day of the immediately preceding fiscal quarter exceeds 130% of the Conversion
Price of the Securities as in effect on that 30th Trading Day; (B) if a Security is called for redemption, at any time prior to the close of business on the 
  

 20 








 
Business Day prior to the Redemption Date, even if the Securities are not otherwise convertible at such time; (C) if the Company elects to (i) distribute to
all holders of the Company’s Common Stock certain rights entitling them to purchase shares of the Company’s Common Stock at less than the last reported Sale Price of a share of the Company’s Common Stock on the trading day preceding
the declaration date for such distribution or (ii) distribute to all holders of the Company’s common stock its assets, debt securities or certain rights to purchase its securities, which distribution has a per share value as determined by the
Company’s Board of Directors exceeding 15% of the last reported Sale Price of its Common Stock on the Trading Day preceding the declaration date for such distribution; or (D) if, at any time during any period that the Securities are rated by
either Moody’s Investors Service, Inc. or Standard & Poor’s Rating Group, the credit rating initially assigned to the Securities by either such rating agency is reduced by two or more ratings levels. 
  
 Upon conversion, the Company may choose to deliver, in lieu of shares of its
Common Stock, cash or a combination of cash and shares of its Common Stock, as described in the Indenture. 
  
 [INCLUDE IF SECURITY IS A GLOBAL SECURITY — In the event of a deposit or withdrawal of an interest in this Security, including an exchange,
transfer, repurchase or conversion of this Security in part only, the Trustee, as custodian of the Depositary, shall make an adjustment on its records to reflect such deposit or withdrawal in accordance with the rules and procedures of the
Depositary.] 
  
 [INCLUDE IF SECURITY IS A RESTRICTED
SECURITY — Subject to certain limitations in the Indenture, at any time when the Company is not subject to Section 13 or 15(d) of the United States Securities Exchange Act of 1934, as amended, upon the request of a Holder of a Restricted
Security, the Company will promptly furnish or cause to be furnished Rule 144A Information (as defined below) to such Holder of Restricted Securities, or to a prospective purchaser of any such security designated by any such Holder, to the extent
required to permit compliance by any such Holder with Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). “Rule 144A Information” shall be such information as is specified pursuant to Rule
144A(d)(4) under the Securities Act (or any successor provision thereto).] 
  
 If an Event of Default shall occur and be continuing, the Principal Amount plus interest accrued and Additional Amounts, if any, through such date on all the Securities may be declared due and payable in the manner
and with the effect provided in the Indenture. 
  
 The Indenture
permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the 
  

 21 








 
Company and the rights of the Holders of the Securities under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not
less than a majority in aggregate Principal Amount of the Outstanding Securities. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate Principal Amount of the Outstanding Securities, on behalf of the
Holders of all the Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be
conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Security. 
  
 As provided in and subject to the
provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall
have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities, the Holders of not less than 25% in aggregate Principal Amount of the Outstanding Securities shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity satisfactory to it, the Trustee shall not have received from the Holders of a majority in Principal Amount of Outstanding
Securities a direction inconsistent with such request, and the Trustee shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted
by the Holder of this Security for the enforcement of any payment of said principal hereof or interest hereon on or after the respective due dates expressed herein or for the enforcement of any conversion right. 
  
 No reference herein to the Indenture and no provision of this Security or of
the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the Principal Amount, Purchase Price or Fundamental Change Repurchase Price of, and interest and Additional Amounts, if any, on, this
Security at the times, place and rate, and in the coin or currency, herein prescribed. 
  
 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at
the office or agency of the Company in The City of New York, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities, of authorized 
  

 22 








 
denominations and for the same aggregate Principal Amount, will be issued to the designated transferee or transferees. 
  
 The Securities are issuable only in registered form in denominations of
$1,000 and any integral multiple of $1,000 above that amount, as provided in the Indenture and subject to certain limitations therein set forth. Securities are exchangeable for a like aggregate Principal Amount of Securities of a different
authorized denomination, as requested by the Holder surrendering the same. 
  
 No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

  
 Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

 Section 2.05.
Legend on Restricted Securities. During the period beginning on the Issue Date and ending on the date two years from such date, any Security including any Security issued in exchange therefor or in lieu thereof, shall be deemed a
“Restricted Security” and shall be subject to the restrictions on transfer provided in the legends set forth on the face of the form of Security in Section 2.02; provided, however, that the term “Restricted
Security” shall not include any Securities as to which restrictions have been terminated in accordance with Section 3.05. All Securities shall bear the applicable legends set forth on the face of the form of Security in Section 2.02. Except
as provided in Section 3.05 and Section 3.10, the Trustee shall not issue any unlegended Security until it has received an Officers’ Certificate from the Company directing it to do so. 
  
 ARTICLE 3 
 THE SECURITIES 
  
 Section 3.01. Title and Terms. The aggregate Principal Amount of Securities which may be authenticated and delivered under this Indenture is
limited to $175,000,000 (subject to increase by up to $35,000,000 in the event the Initial Purchasers exercise the option granted to them in the Purchase Agreement), except for Securities authenticated and delivered upon registration or transfer of,
or in exchange for, or in lieu of, other Securities pursuant to Section 3.04, 3.05, 3.06, 9.06, 11.06, 11.12 or 13.02. 
  
 The Securities shall be known and designated as the “3.0% Senior Convertible Notes Due 2023” of the Company. The Principal Amount shall be
payable on the Stated Maturity. 
  
 The Principal Amount and
accrued interest and Additional Amounts, if any, on the Securities shall be payable at the office or agency of the Company in The City of New York maintained for such purpose and at any other office or agency maintained by the Company for such
purpose; provided, however, that at the option of the Company payments may be made by wire transfer or by check 
  

 29 








 
mailed to the address of the Person entitled thereto as such address shall appear in the Security Register. 
  
 The Securities shall not have the benefit of a sinking fund. 
  
 The Securities shall not be superior in right of payment to, and shall rank
pari passu with, all other unsecured and unsubordinated indebtedness of the Company. 
  
 Section 3.02. Denominations. The Securities shall be issuable only in registered form without coupons and in denominations of $1,000 and any integral multiple of $1,000 above that amount. 
  
 Section 3.03. Execution, Authentication, Delivery and Dating. The
Securities shall be executed on behalf of the Company by its Chairman of the Board, its President or one of its Vice Presidents, attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Securities
may be manual or facsimile. 
  
 Securities bearing the manual or
facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of
such Securities or did not hold such offices at the date of such Securities. 
  
 At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities executed by the Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities. The Company Order shall specify the amount of Securities to be authenticated, and shall further specify the amount of such Securities to be issued as a Global Security or as Physical Securities. The
Trustee in accordance with such Company Order shall authenticate and deliver such Securities as in this Indenture provided and not otherwise. 
  
 Each Security shall be dated the date of its authentication. 
  
 No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly
authenticated and delivered hereunder. 
  
 Section 3.04.
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, 
  

 30 








 
typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which
they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities. 
  
 If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary Securities shall be exchangeable for definitive Securities upon surrender of the temporary Securities at any office or agency of the
Company designated pursuant to Section 10.02, 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 3.05. Registration; Registration of Transfer and Exchange;
Restrictions on Transfer. (a) The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency designated pursuant to Section 10.02 being herein
sometimes collectively referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The
Trustee is hereby appointed “Security Registrar” (the “Security Registrar”) for the purpose of registering Securities and transfers of Securities as herein provided. 
  
 Upon surrender for registration of transfer of any Security at an office or
agency of the Company designated pursuant to Section 10.02 for such purpose, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of any
authorized denominations and of a like aggregate Principal Amount and tenor, each such Security bearing such restrictive legends as may be required by this Indenture (including Section 2.02, 2.05 and 3.10). 
  
 At the option of the Holder and subject to the other provisions of this
Section 3.05 and to Section 3.10, Securities may be exchanged for other Securities of any authorized denominations and of a like aggregate Principal Amount and tenor, upon surrender of the Securities to be exchanged at such office or agency.
Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. 
  
 All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same 
  

 31 








 
debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. 
  
 Every Security presented or surrendered for registration of transfer or for
exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his attorney
duly authorized in writing. As a condition to the registration of transfer of any Restricted Securities, the Company or the Trustee may require evidence satisfactory to them as to the compliance with the restrictions set forth in the legend on such
securities. 
  
 Except as provided in the following sentence and
in Section 3.10, all Securities originally issued hereunder and all Securities issued upon registration of transfer or exchange or replacement thereof shall be Restricted Securities and shall bear the legend required by Sections 2.02 and 2.05,
unless the Company shall have delivered to the Trustee (and the Security Registrar, if other than the Trustee) a Company Order stating that the Security is not a Restricted Security and may be issued without such legend thereon. Securities which are
issued upon registration of transfer of, or in exchange for, Securities which are not Restricted Securities shall not be Restricted Securities and shall not bear such legend. 
  
 No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require
payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.04 or 9.06 not involving any
transfer. 
  
 The Company shall not be required to exchange or
register a transfer of any Security (i) during the 15-day period immediately preceding the mailing of any notice of redemption of any Security, (ii) after any notice of redemption has been given to Holders of Securities, except, where such notice
provides that such Security is to be redeemed only in part, the Company shall be required to exchange or register a transfer of the portion thereof not to be redeemed, (iii) that has been surrendered for conversion or (iv) as to which a Purchase
Notice or Fundamental Change Repurchase Notice has been delivered and not withdrawn, except, where such Purchase Notice or Fundamental Change Repurchase Notice provides that such Security is to be purchased only in part, the Company shall be
required to exchange or register a transfer of the portion thereof not to be purchased. 
  
 (b) Beneficial ownership of every Restricted Security shall be subject to the restrictions on transfer provided in the legends required to be set forth on the face of each Restricted Security pursuant to Sections 2.02
and 2.05, unless such restrictions on transfer shall be terminated in accordance with this Section 3.05(b) 
  

 32 








 
or Section 3.10. The Holder of each Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by such restrictions on transfer.

  
 The restrictions imposed by this Section 3.05 and 2.02, 2.05
and 3.10 upon the transferability of any particular Restricted Security shall cease and terminate upon delivery by the Company to the Trustee of an Officers’ Certificate stating that such Restricted Security has been sold pursuant to an
effective Resale Registration Statement under the Securities Act or transferred in compliance with Rule 144 under the Securities Act (or any successor provision thereto). Any Restricted Security as to which the Company has delivered to the Trustee
an Officers’ Certificate that such restrictions on transfer shall have expired in accordance with their terms or shall have terminated may, upon surrender of such Restricted Security for exchange to the Security Registrar in accordance with the
provisions of this Section 3.05, be exchanged for a new Security, of like tenor and aggregate Principal Amount, which shall not bear the restrictive legends required by Sections 2.02 and 2.05. The Company shall inform the Trustee in writing of the
effective date of any Resale 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 Resale
Registration Statement. 
  
 As used in the preceding two
paragraphs of this Section 3.05, the term “transfer” encompasses any sale, pledge, transfer or other disposition of any Restricted Security. 
  
 (c) Neither the Trustee nor any of its agents shall (i) have any duty to monitor compliance with or with respect to any federal or state or other
securities or tax laws or (ii) have any duty to obtain documentation on any transfers or exchanges other than as specifically required hereunder. 
  
 Section 3.06. Mutilated, Destroyed, Lost and Stolen Securities. If any mutilated Security is surrendered to the Trustee, the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor a new Security of like tenor and Principal Amount and bearing a number not contemporaneously outstanding. 
  
 If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or
theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by
a bona fide purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and Principal Amount and bearing a number not contemporaneously
outstanding. 
  

 33 








 In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and
payable or has been called for redemption in full, the Company in its discretion may, instead of issuing a new Security, pay such Security. 
  
 Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 
  
 Every new Security issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities
duly issued hereunder. 
  
 The provisions of this Section are
exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 
  
 Section 3.07. Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal and interest on such Security and for all
other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. 
  
 Section 3.08. Book-entry Provisions for Global Securities. (a) The
Global Securities initially shall (i) be registered in the name of the Depositary or the nominee of such Depositary, (ii) be delivered to the Trustee as custodian for the Depositary and (iii) bear legends as set forth on the face of the form of
Security in Section 2.02. 
  
 Members of, or participants in, the
Depositary (“Agent Members”) shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Security, and the Depositary may
be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of the Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall 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 impair, as between the Depositary and its Agent 
  

 34 








 
Members, the operation of customary practices governing the exercise of the rights of any Holder. 
  
 (b) Transfers of the Global Securities shall be limited to transfers in
whole, but not in part, to the Depositary, its successors or their respective nominees. Interests of beneficial owners in a Global Security may be transferred or exchanged, in whole or in part, for Physical Securities in accordance with the rules
and procedures of the Depositary and the provisions of Section 3.10. In addition, Physical Securities shall be transferred to all beneficial owners in exchange for their beneficial interests in the Global Securities if (A) such Depositary has
notified the Company (or the Company becomes aware) that the Depositary (i) is unwilling or unable to continue as Depositary for such Global Security or (ii) has ceased to be a clearing agency registered under the Exchange Act when the Depositary is
required to be so registered to act as such Depositary and, in both such cases, no successor Depositary shall have been appointed within 90 days of such notification or of the Company becoming aware of such event or (B) there shall have occurred and
be continuing an Event of Default with respect to such Global Security and the Outstanding Securities shall have become due and payable pursuant to Section 5.02 and the Trustee requests that Physical Securities be issued; provided that Holders of
Physical Securities offered and sold in reliance on Rule 144A shall have the right, subject to applicable law, to request that such Securities be exchanged for interests in the applicable Global Security. 
  
 (c) In connection with any transfer or exchange of a portion of the
beneficial interest in the Global Security to beneficial owners pursuant to paragraph (b), the Security Registrar shall (if one or more Physical Securities are to be issued) reflect on its books and records the date and a decrease in the Principal
Amount of the Global Security in an amount equal to the Principal Amount of the beneficial interest in the Global Security to be transferred, and the Company shall execute, and the Trustee shall authenticate and deliver, one or more Physical
Securities of like tenor and amount. 
  
 (d) In connection with
the transfer of the entire Global Security to beneficial owners pursuant to paragraph (b), the Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and
deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in the Global Security, an equal aggregate Principal Amount of Physical Securities of authorized denominations and the same tenor. 
  
 (e) Any Physical Security constituting a Restricted Security delivered in
exchange for an interest in the Global Security pursuant to paragraph (c) or (d) shall, except as otherwise provided by paragraphs (a)(i)(x) and (c) of Section 3.10, bear the legend regarding transfer restrictions applicable to the Physical
Securities set forth on the face of the form of Security in Section 2.02. 
  

 35 








 (f) The Holder of the Global Securities may grant proxies and otherwise authorize any Person, including
Agent Members 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. 
  
 Section 3.09. Cancellation. The Company at any time may deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee for cancellation any Securities previously authenticated hereunder which the Company has not issued and
sold. The Trustee shall cancel and dispose of all Securities surrendered for registration of transfer, exchange, payment, purchase, repurchase, redemption, conversion (pursuant to Article 13 hereof) or cancellation in accordance with its customary
practices. If the Company shall acquire any of the Securities, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless and until the same are delivered to the Trustee for
cancellation. The Company may not issue new Securities to replace Securities it has paid in full or delivered to the Trustee for cancellation. 
  
 Section 3.10. Special Transfer Provisions. (a) Transfers to Non-U.S. Persons. The following provisions shall apply with respect to the
registration of any proposed transfer of a Security constituting a Restricted Security to any Non-U.S. Person to which Securities in the form of Global Securities cannot be issued: 
  
 (i) the Security Registrar shall register the transfer of any Security constituting a Restricted Security,
whether or not such Security bears the legend required by Sections 2.02 and 2.05, if (x) the requested transfer is after the second anniversary of the Issue Date of such Security or (y) the proposed transferor has delivered to the Security Registrar
a certificate substantially in the form of Exhibit A hereto, together with such other certifications, legal opinions or other information as the Company may reasonably require to confirm that such transfer is being made pursuant to an
exemption from, or in a transaction not subject to, the registration requirements of the Securities Act; and 
  
 (ii) if the proposed transferor is an Agent Member holding a beneficial interest in the Global Security, upon receipt by the Security
Registrar of (x) the certificate, if any, required by paragraph (i) above and instructions given in accordance with the Depositary’s and the Security Registrar’s procedures, 
  
 whereupon (1) the Security Registrar shall reflect on its books and records the date and (if the transfer does not involve a transfer of
outstanding Physical Securities) a decrease in the Principal Amount of the Global Security in an amount equal to the Principal Amount of the beneficial interest in the Global 
  

 36 








 
Security to be transferred, and (b) the Company shall execute and the Trustee shall authenticate and deliver one or more Physical Securities of like tenor
and amount. 
  
 (b) Transfers to QIBs. The following
provisions shall apply with respect to the registration of any proposed transfer of a Security constituting a Restricted Security to a QIB (excluding transfers to Non-U.S. Persons): 
  
 (i) the Security Registrar shall register the transfer if such transfer is being made by a proposed
transferor who has checked the box provided for on the form of Security stating, or has otherwise advised the Company and the Security Registrar in writing, that the sale has been made in compliance with the provisions of Rule 144A to a transferee
who has signed the certification provided for on the form of Security stating, or has otherwise advised the Company and the Security Registrar in writing, that it is purchasing the Security for its own account or an account with respect to which it
exercises sole investment discretion and that it and any such account is a QIB within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding
the Company as it has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided
by Rule 144A; and 
  
 (ii) if the proposed
transferee is an Agent Member, and the Securities to be transferred consist of Physical Securities which after transfer are to be evidenced by an interest in the Global Security, upon receipt by the Security Registrar of instructions given in
accordance with the Depositary’s and the Security Registrar’s procedures, the Security Registrar shall reflect on its books and records the date and an increase in the Principal Amount of the Global Security in an amount equal to the
Principal Amount of the Physical Securities to be transferred, and the Trustee shall cancel the Physical Securities so transferred. 
  
 (c) Private Placement Legend. Upon the registration of transfer, exchange or replacement of Securities not bearing the legends required by Sections
2.02 and 2.05, the Security Registrar shall deliver Securities that do not bear such legends. Upon the registration of transfer, exchange or replacement of Securities bearing the legends required by Sections 2.02 and 2.05, the Security Registrar
shall deliver only Securities that bear such legends unless (i) the circumstance contemplated by paragraph (a)(i)(x) of this Section 3.10 exists or (ii) there is delivered to the Security Registrar an Opinion of Counsel reasonably satisfactory to
the Company and the Trustee to the effect that neither such legend 
  

 37 








 
nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act. 
  
 (d) General. By its acceptance of any Security bearing the legends
required by Sections 2.02 and 2.05, each Holder of such a Security acknowledges the restrictions on transfer of such Security set forth in this Indenture and in such legends and agrees that it will transfer such Security only as provided in this
Indenture. 
  
 The Security Registrar shall retain, in accordance
with its customary procedures, copies of all letters, notices and other written communications received pursuant to this Section 3.10. The Company shall have the right to inspect and make copies of all such letters, notices or other written
communications at any reasonable time upon the giving of reasonable written notice to the Security Registrar. 
  
 Section 3.11. CUSIP Numbers. The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and, if so, the
Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as
contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will
promptly notify the Trustee of any change in the “CUSIP” numbers.

shall cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of Securities herein expressly provided for), and the Trustee, on demand of and at the expense of the Company, shall execute proper
instruments acknowledging satisfaction and discharge of this Indenture, when

 Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under
Section 6.07 and, if money shall have been deposited with the Trustee pursuant to subclause (ii) of Clause (a) of this Section, the obligations of the Trustee under Section 4.02 and the last paragraph of Section 10.03 shall survive. 
  
 Section 4.02. Application of Trust Money. Subject to the provisions of
the last paragraph of Section 10.03, all money deposited with the Trustee pursuant to Section 4.01 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal and interest and Additional Amounts, if any, for whose payment such money has been
deposited with the Trustee.

creditors, or the admission by it in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company in furtherance of any such action. 
  
 Section 5.02. Acceleration of Maturity; Rescission and Annulment. (a)
If an Event of Default (other than those specified in 5.01(g) and 5.01(h)) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in aggregate Principal Amount of the Outstanding Securities may declare
the Principal Amount plus accrued and unpaid interest and Additional Amounts, if any, on all the Outstanding Securities to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any
such declaration such Principal Amount plus accrued and unpaid interest and Additional Amounts, if any, shall become immediately due and payable. 
  
 Notwithstanding the foregoing, in the case of an Event of Default specified in Section 5.01(g) and 5.01(h), the Principal Amount plus accrued and unpaid
interest and Additional Amounts, if any, on all Outstanding Securities will ipso facto become due and payable without any declaration or other Act on the part of the Trustee or any Holder. 
  
 (b) At any time after such a declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in aggregate Principal Amount of the Outstanding Securities, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its consequences if 
  
 (i) the Company has paid or deposited with the Trustee a sum sufficient to pay 
  
 (A) all overdue interest on all Securities, 
  

 41 








 (B) the Principal Amount plus accrued and unpaid interest and Additional Amounts, if any,
Redemption Price, Purchase Price or Fundamental Change Repurchase Price, as applicable, on any Securities which have become due otherwise than by such declaration of acceleration, and 
  
 (C) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.07; and 
  
 (ii) all Events of Default, other than the non-payment of the Principal Amount plus accrued and unpaid interest and Additional Amounts, if
any, on Securities which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.12. 
  
 No such rescission shall affect any subsequent default or impair any right consequent thereon. 
  
 Section 5.03. Collection of Indebtedness and Suits for Enforcement by
Trustee. The Company covenants that if: 
  
 (i) default is made in the payment of any interest on any Security when such interest becomes due and payable, and such default continues for a period of 30 days, or 
  
 (ii) default is made in the payment of the Principal Amount plus accrued and unpaid interest and Additional
Amounts, if any, at the Maturity thereof or in the payment of the Redemption Price, the Purchase Price or the Fundamental Change Repurchase Price in respect of any Security, 
  
 the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and
payable on such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel. 
  
 If an Event of Default occurs and is continuing,
the Trustee may, but shall not be obligated to, pursue any available remedy to collect the payment of the principal amount plus accrued but unpaid interest and Additional Amounts, if any, on the Securities 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 
  

 42 








 
the proceeding. A delay or omission by the Trustee or any Holder in 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 5.04. Trustee May File Proofs of Claim. In case of any judicial proceeding relative to the Company (or any
other obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have
claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any
custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to
the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee under
Section 6.07. 
  
 No provision of this Indenture shall be deemed
to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding. 
  
 Section 5.05. Application of Money Collected. Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the
distribution of such money to Holders, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 
  
 FIRST: To the payment of all amounts due the Trustee under Section 6.07; and 
  
 SECOND: To the payment of the amounts then due and unpaid on
the Securities for the Principal Amount, Redemption Price, Purchase Price, Fundamental Change Repurchase Price or interest and Additional Amounts, if any, as the case may be, in respect of which or for the benefit of which such money has been
collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities. 
  

 43 








 Section 5.06. Limitation on Suits. No Holder of any Security shall have any right to institute any
proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder (other than in the case of an Event of Default specified in Section 5.01(a) or 5.01(b)), unless:

  
 (i) such Holder has previously given written
notice to the Trustee of a continuing Event of Default; 
  
 (ii) the Holders of not less than 25% in aggregate Principal Amount of the Outstanding Securities shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own
name as Trustee hereunder; 
  
 (iii) such Holder
or Holders have offered to the Trustee indemnity reasonably satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with such request; 
  
 (iv) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to
institute any such proceeding; and 
  
 (v) no
direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate Principal Amount of the Outstanding Securities; 
  
 it being understood and intended that no one or more Holders shall have any right in any
manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right
under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all the Holders. 
  
 Section 5.07. Unconditional Right of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to
receive payment of the Principal Amount, Redemption Price, Purchase Price, Fundamental Change Repurchase Price or interest and Additional Amounts, 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, Purchase Date or Fundamental Change Purchase Date, as applicable, and to convert the Securities in accordance with Article 13, 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 5.08. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under
this 
  

 44 








 Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the
Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all
rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 
  
 Section 5.09. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost
or stolen Securities in the last paragraph of Section 3.06, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall
not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
  
 Section 5.10. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event of Default shall impair any such right or
remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by the Holders, as the case may be. 
  
 Section 5.11. Control by Holders. The Holders of a majority in Principal Amount of the Outstanding Securities shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the
Trustee or exercising any trust or power conferred on the Trustee, provided that: 
  
 (i) such direction shall not be in conflict with any rule of law or with this Indenture; and 
  
 (ii) the Trustee may take any other action deemed proper by
the Trustee which is not inconsistent with such direction. 
  
 Section 5.12. Waiver of Past Defaults. The Holders of not less than a majority in Principal Amount of the Outstanding Securities may on behalf of the Holders of all the Securities waive any past Default hereunder and its
consequences, except a Default: 
  
 (i) Described
in Section 5.01(a) or (b); or 
  

 45 








 (ii) in respect of a covenant or provision hereof which under Article 9 cannot be
modified or amended without the consent of the Holder of each Outstanding Security affected. 
  
 Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other Default or impair any right consequent thereon. 
  
 Section 5.13. 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, in either case in respect of the
Securities, a court may require any party litigant in such suit to file an undertaking to pay the costs of the suit, and the court may assess reasonable costs, including reasonable attorney’s fees, against any party litigant in the suit having
due regard to the merits and good faith of the claims or defenses made by the party litigant; but the provisions of this Section shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by
any Holder, or group of Holders, holding in the aggregate more than 10% in Principal Amount of the Outstanding Securities, or to any suit instituted by any Holder for the enforcement of the payment of the Principal Amount or interest on any Security
on or after Maturity of such Security, the Redemption Price, the Purchase Price or the Fundamental Change Repurchase Price. 
  
 Section 5.14. Waiver of Stay or Extension Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time
insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture;
and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay, or impede the execution of any power herein granted to the Trustee, but will
suffer and permit the execution of every such power as though no such law had been enacted. 
  
 ARTICLE 6 
 THE TRUSTEE 
  
 Section 6.01. Certain Duties and Responsibilities. The duties and
responsibilities of the Trustee shall be as provided by the Trust Indenture Act. Except during the continuance of an Event of Default, the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this
Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee. In case an Event of Default with respect to the 
  

 46 








 
Securities has occurred (which has not been cured or waived), the Trustee shall exercise the rights and powers vested in it by this Indenture, and use the
same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. Notwithstanding the foregoing, no provision of this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers. Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. 
  

Section 6.02. Notice of Defaults. The Trustee shall give the Holders notice of any Default hereunder within 60 days after the occurrence
thereof; provided, that (except in the case of any Default in the payment of Principal Amount, interest or Additional Amounts, if any, on any of the Securities, Redemption Price, Purchase Price or Fundamental Change Repurchase Price), the Trustee
shall be protected in withholding such notice if and so long as a trust committee of directors or trustees and/or a Responsible Officer of the Trustee in good faith determines that the withholding of such notice is in the interest of the holders of
Securities. 
  
 Section 6.03. Certain Rights Of Trustee.
Subject to the provisions of Section 6.01: 
  
 (a) the
Trustee may conclusively rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of
indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties; 
  
 (b) any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order and any resolution of
the Board of Directors of the Company may be sufficiently evidenced by a Board Resolution; 
  
 (c) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other
evidence be herein specifically prescribed) may, in the absence of bad faith on its part, request and rely upon an Officers’ Certificate; 
  
 (d) the Trustee may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon; 
  

 47 








 (e) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this
Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities which might
be incurred by it in compliance with such request or direction; 
  
 (f) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other
evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit; and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the sole cost of the Company and shall incur no liability or additional liability of any kind by reason of such
inquiry or investigation. 
  
 (g) the Trustee may execute any of
the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due
care by it hereunder; 
  
 (h) the Trustee shall not be charged
with knowledge of any Default or Event of Default with respect to the Securities unless either (i) a Responsible Officer shall have actual knowledge of such Default or Event of Default or (ii) written notice of such Default or Event of Default shall
have been given to the Trustee by the Company or any other obligor on such Securities or by any Holder of such Securities; 
  
 (i) the Trustee shall not be liable for any action taken, suffered or omitted by it in good faith and reasonably believed by it to be authorized or within
the discretion or rights or powers conferred upon it by this Indenture; 
  
 (j) the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities
hereunder, and each agent, custodian, director, officer, employee and other Person employed to act hereunder; and 
  
 (k) the Trustee may request that the Company deliver an Officers’ Certificate setting forth the names of individuals and/or titles of officers
authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may be signed by any person authorized to sign an Officers’ 
  

 48 








 
Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded. 
  
 (l) The permissive rights of the Trustee to take certain actions under this
Indenture shall not be construed as a duty unless so specified herein. 
  
 Section 6.04. Not Responsible for Recitals. The recitals contained herein and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company, and the Trustee assumes no
responsibility for their correctness. The Trustee makes no representations as to the validity, sufficiency or priority of this Indenture or of the Securities. The Trustee shall not be accountable for the use or application by the Company of
Securities or the proceeds thereof. 
  
 Section 6.05. May Hold
Securities. The Trustee, any Paying Agent, any Security Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Section 6.08 and 6.13, may otherwise deal
with the Company with the same rights it would have if it were not Trustee, Paying Agent, Security Registrar or such other agent. 
  
 Section 6.06. Money Held in Trust. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent
required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed in writing with the Company. 
  
 Section 6.07. Compensation and Reimbursement. The Company agrees: 
  
 (i) to pay to the Trustee from time to time such
compensation for all services rendered by it hereunder as the Company and the Trustee shall from time to time agree in writing (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express
trust); 
  
 (ii) except as otherwise expressly
provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the
expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or willful misconduct; and 
  
 (iii) to indemnify the Trustee and any predecessor Trustee for, and to hold it harmless against, any loss,
liability or expense including taxes (other than taxes based upon, measured by or determined by the income of the Trustee) incurred without negligence or willful misconduct 
  

 49 








 
on its part, arising out of or in connection with the acceptance or administration of this trust, including the reasonable costs and expenses of defending
itself against any claim (whether assessed by the Company, by any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder. 
  
 The obligations of the Company under this Section 6.07 shall survive the
resignation or removal of the Trustee and the satisfaction and discharge of this Indenture. To secure the Company’s payment obligations in this Section 6.07, 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 principal and interest on the Securities. Such lien shall survive the resignation or removal of the Trustee and the satisfaction and discharge of this Indenture. When the Trustee incurs
expenses or renders services after a Default or an Event of Default specified in 5.01(g) or 5.01(h) hereof occurs, the expenses and the compensation for the services (including, the fees and expenses of its agents and counsel) are intended to
constitute expenses of administration under U.S. Code, Title 11 or any other similar foreign, federal or state law for the relief of debtors. 
  
 Section 6.08. Disqualification; Conflicting Interests. If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust
Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. 
  
 Section 6.09. Corporate Trustee Required; Eligibility. There shall at
all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has, or whose parent banking company has, a combined capital and surplus of at least $50,000,000. If such Person
publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and
with the effect hereinafter specified in this Article.

 (b) The Trustee may
resign at any time by giving written notice thereof to the Company. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice 
  

 50 








 
of resignation, the resigning Trustee may petition any court of competent jurisdiction at the expense of the Trustee for the appointment of a successor
Trustee. 
  
 (c) The Trustee may be removed at any time by Act of
the Holders of majority in Principal Amount of the Outstanding Securities, delivered to the Trustee and to the Company. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the
notice of removal, the Trustee being removed may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities. 
  
 (d) If at any time: 
  
 (i) the Trustee shall fail to comply with Section 6.08 after
written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months, or 
  
 (ii) the Trustee shall cease to be eligible under Section 6.09 and shall fail to resign after written request therefor by the Company or
by any such Holder, or 
  
 (iii) the Trustee

 (iv) a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or
of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 
  
 then, in any such case, (A) the Company by a Company Order may remove the Trustee, or (B) subject to Section 5.13, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of
such Holder and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
  
 (e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of
Trustee for any cause, the Company, by a Company Order, shall promptly appoint a successor Trustee. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act
of the Holders of a majority in Principal Amount of the Outstanding Securities delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor
Trustee and supersede the successor Trustee appointed by the Company. If no successor Trustee shall have been so appointed by the Company or the Holders and 
  

 51 








 
accepted appointment in the manner hereinafter provided, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of
himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee. 
  
 (f) The Company shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee to all Holders in the

 Section 6.11. Acceptance of Appointment by Successor. Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the
Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring
to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. Upon request of any such
successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts. 
  
 No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be
qualified and eligible under this Article. 
  
 Section 6.12.
Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to
which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee by sale or otherwise, shall be the successor of the Trustee hereunder, provided such corporation shall be
otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee
then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated
such Securities. 
  
 Section 6.13. Preferential Collection of
Claims Against. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon 
  

 52 








 
the Securities), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any
such other obligor).

 ARTICLE 10 
 COVENANTS 
  
 Section 10.01. Payments. The Company shall duly and punctually make all payments in respect of the Securities in accordance with the terms of the Securities and this Indenture. 
  
 Any payments made or due pursuant to this Indenture shall be considered paid
on the applicable date due if by 10:00 a.m., New York City time, on such date the Paying Agent holds, in accordance with this Indenture, cash sufficient to pay all such amounts then due. Payment of the principal of and interest and Additional
Amounts, if any, on the Securities shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

Securities and this Indenture may be served, which shall initially be the Corporate Trust Office of the Trustee. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency.
If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. 
  
 The Company may also from time to time designate one or more other offices or agencies (in or outside the Borough of Manhattan, The City of New York)
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 the Borough of Manhattan, The City of New York, for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of
any such other office or agency. 
  
 Section 10.03. Money for
Security Payments to be Held in Trust. If the Company shall at any time act as its own Paying Agent, it shall, on or before each 
  

 59 








 
due date of any payment in respect of any of the Securities, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to
make the payment so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and shall promptly notify the Trustee of its action or failure so to act. 
  
 Whenever the Company shall have one or more Paying Agents, it will, prior to
each due date of any payment in respect of any Securities, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of its action or failure so to act. 
  
 The Company shall cause each Paying Agent other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent
will (i) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and (ii) during the continuance of any default by the Company (or any other obligor upon the Securities) in the making of any payment in respect of the
Securities, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent as such. 
  
 The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent;
and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money. 
  
 Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the making of payments in respect of any Security and
remaining unclaimed for two years after such payment has become due shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in The City of New York or San Francisco, California, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less 
  

 60 








 
than 30 days from the date of such publication, any unclaimed balance of such money then remaining shall be repaid to the Company. In the absence of a
written request from the Company to return funds remaining unclaimed for two years after such payment has become due to the Company, the Trustee shall from time to time deliver all unclaimed payments to or as directed by applicable escheat
authorities, as determined by the Trustee in its sole discretion, in accordance with the customary practices and procedures of the Trustee. Any such unclaimed funds held by the Trustee pursuant to this Section 10.03 shall be held uninvested and
without any liability for interest. 
  
 Section 10.04.
Statement by Officers as to Default. The Company will deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, an Officers’ Certificate, stating whether or not to the knowledge

Company shall be in Default, specifying all such Defaults and the nature and status thereof of which they may have knowledge. 
  
 The Company shall deliver to the Trustee, as soon as possible and in any event within 30 days after the Company becomes aware of the occurrence of any
Event of Default or an event which, with notice or the lapse of time or both, would constitute an Event of Default, an Officers’ Certificate setting forth the details of such Event of Default or default and the action which the Company proposes
to take with respect thereto. 
  
 Section 10.05. Existence.
Subject to Article 8, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights (charter and statutory) and franchises; provided, however, that the Company
shall not be required to preserve any such right or franchise if the Board of Directors of the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is
not disadvantageous in any material respect to the Holders. 
  
 Section 10.06. Reports and Delivery of Certain Information. Whether or not required by the rules and regulations of the Commission, so long as any Securities are outstanding, the Company shall promptly furnish to the Trustee (i) all
quarterly and annual financial information that is substantially equivalent to that which would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if the Company were required to file such Forms, including a
“Management’s Discussion and Analysis of Financial Condition and Results of Operations” section and, with respect to the annual information only, a report thereon by the Company’s certified independent accountants and (ii) all
reports that are substantially equivalent to that which would be required to be filed with the Commission on Form 8-K if the Company were required to file such reports; 
  

 61 








 
provided that in each case the delivery of materials to the Trustee by electronic means shall be deemed to be “furnished” to the Trustee for
purposes of this Section 10.06. 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 exclusively on Officers’ Certificates). In addition, whether or
not required by the rules and regulations of the Commission, the Company shall file a copy of all such information with the Commission for public availability (unless the Commission will not accept such a filing) and make such information available
to investors who request it in writing. So long as any of the Securities remain Outstanding, the Company shall make available to any prospective purchaser of Securities or beneficial owner of Securities in connection with any sale thereof the
information required by Rule 144A(d)(4) under the Securities Act, until the earlier of (a) such time as the Holders thereof have disposed of such Securities pursuant to an effective Resale Registration Statement or Rule 144 under the Securities Act
and (b) the date that is two years from the Issue Date. 
  
 Section 10.07. Resale of Certain Securities. During the period beginning on the Issue Date and ending on the date that is two years from the Issue Date, the Company shall not, and shall not permit any of its
“affiliates” (as defined under Rule 144 under the Securities Act or any successor provision thereto) to, resell any Securities which constitute “restricted securities” under Rule 144 that have been reacquired by any
of them. The Trustee shall have no responsibility in respect of the Company’s performance of its agreement in the preceding sentence. 
  
 Section 10.08. Book-entry System. If the Securities cease to trade in the Depositary’s book-entry settlement system, the Company covenants and
agrees that it shall use reasonable efforts to make such other book entry arrangements that it determines are reasonable for the Securities. 
  
 Section 10.09. Additional Amounts under the Registration Rights Agreement. If at any time Additional Amounts become payable by the Company pursuant
to the Registration Rights Agreement, the Company shall promptly deliver to the Trustee a certificate to that effect and stating (i) the amount of such Additional Amounts that are payable and (ii) the date on which such Additional Amounts are
payable pursuant to the terms of the Registration Rights Agreement. Unless and until a Responsible Officer of the Trustee receives such a certificate, the Trustee may assume without inquiry that no Additional Amounts are payable. If the Company has
paid Additional Amounts directly to the Persons entitled to such Additional Amounts, the Company shall deliver to the Trustee a certificate setting forth the particulars of such payment. 
  

 62 








 Section 10.10. Information for IRS Filings. The Company shall provide to the Trustee on a timely
basis such information as the Trustee requires to enable the Trustee to prepare and file any form required to be submitted by the Company with the Internal Revenue Service and the Holders of the Notes.

 Section 11.01. Right to Redeem; Notices to Trustee. The Securities are redeemable as a whole, or from time to time in part, at any time commencing
on June 8, 2010 at the option of the Company at the Redemption Price, together with accrued and unpaid interest and Additional Amounts, if any, to, but excluding, the Redemption Date. 
  
 The Company shall give the notice to the Trustee provided for in this Section 11.01 by a Company Order, at least 45, but not
more than 60, days before the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee). 
  
 Section 11.02. Selection of Securities to be Redeemed. If less than all the Securities are to be redeemed, the Trustee shall select the Securities
to be redeemed pro rata or by lot or by any other 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). The Trustee shall make the
selection within 7 days from its receipt of the notice from the Company delivered pursuant to the second paragraph of Section 11.01 from Outstanding Securities not previously called for redemption. 
  
 Securities and portions of them the Trustee selects shall be in Principal
Amounts of $1,000 or integral multiples 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 Securities to be redeemed. 
  
 If any
Security selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the
portion selected for redemption. Securities which have been converted during a selection of Securities to be redeemed may be treated by the Trustee as outstanding for the purpose of such selection. 
  
 Section 11.03. 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.

 (ii) the Redemption Price; 
  
 (iii) the Conversion Price; 
  
 (iv) the name and address of the Paying Agent and Conversion
Agent; 
  
 (v) that Securities called for
redemption may be converted at any time before the close of business on the Business Day immediately preceding the Redemption Date; 
  
 (vi) that Holders who want to convert Securities must satisfy the requirements set forth therein and in this Indenture; 
  
 (vii) that Securities called for redemption must be
surrendered to the Paying Agent for cancellation to collect the Redemption Price; 
  
 (viii) if fewer than all the outstanding Securities are to be redeemed, the certificate number and Principal Amounts of the particular
Securities to be redeemed; 
  
 (ix) that, unless
the Company defaults in making payment of such Redemption Price, interest on Securities called for redemption will cease to be outstanding and interest and Additional Amounts, if any, cease to accrue on and after the Redemption Date; and 

 
 (x) the CUSIP number of the Securities. 
  
 At the Company’s written request delivered at least 30 days prior to the
date such notice is to be given (unless a shorter time period shall be acceptable to the Trustee), the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense. 
  
 Section 11.04. 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. Upon
surrender to the Paying Agent, such Securities shall be paid at the Redemption Price stated in the notice. 
  
 Section 11.05. Deposit of Redemption Price. Prior to 10:00 a.m. (New York City Time) on a Redemption Date, the Company shall deposit with the

  

 64 








 
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 13. 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 11.06. 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. The Company shall not be required to (i) issue, register the transfer of, or exchange any Securities during a period of 15 days before the Redemption Date or (ii)
register the transfer of, or exchange any, Securities so selected for redemption, in whole or in part, except the unredeemed portion of any Security being redeemed in part. 
  
 Section 11.07. Conversion Arrangement on Call for Redemption. In connection with any redemption of Securities, the
Company may arrange for the purchase and conversion of any Securities called for redemption by an agreement with one or more investment bankers or other purchasers to purchase such Securities by paying to the Trustee in trust for the
Securityholders, on or prior to 10:00 a.m. New York City time on the Redemption Date, an amount that, together with any amounts deposited with the Trustee by the Company for the redemption of such Securities, is not less than the Redemption Price of
such Securities. Notwithstanding anything to the contrary contained in this Article 11, the obligation of the Company to pay the Redemption Price of such Securities shall be deemed to be satisfied and discharged to the extent such amount is so paid
by such purchasers. If such an agreement is entered into, any Securities not duly surrendered for conversion by the Holders thereof may, at the option of the Company, be deemed, to the fullest extent permitted by law, acquired by such purchasers
from such Holders and (notwithstanding anything to the contrary contained in Article 13) surrendered by such purchasers for conversion, all as of immediately prior to the close of business on the Business Day prior to the Redemption Date, subject to
payment of the above amount as aforesaid. The Trustee shall hold and pay to the Holders whose Securities are selected for redemption any such amount paid to it for purchase and conversion in the same manner as it would moneys deposited with it by
the Company for the redemption of Securities. Without the Trustee’s prior written consent, no arrangement between the Company and such purchasers for the purchase and conversion of any Securities shall increase or otherwise affect any of the
powers, duties, responsibilities or obligations of the Trustee as set forth in this Indenture, and the 
  

 65 








 
Company agrees to indemnify the Trustee from, and hold it harmless against, any loss, liability or expense arising out of or in connection with any such
arrangement for the purchase and conversion of any Securities between the Company and such purchasers, including the costs and expenses incurred by the Trustee in the defense of any claim or liability arising out of or in connection with the
exercise or performance of any of its powers, duties, responsibilities or obligations under this Indenture, except in the case of the Trustee’s negligence or willful misconduct. 
  
 Section 11.08. Purchase of Securities at Option of the Holder.

the terms thereof as of June 1, 2010 and June 1, 2018 (each, a “Purchase Date”), at the applicable Purchase Price, at the option of the Holder thereof, upon:

 (2) delivery of such Security to the Paying Agent for cancellation prior to, on or after the Purchase Date (together with all necessary
endorsements) at the offices of the Paying Agent, such delivery being a condition to receipt by the Holder of the Purchase Price therefor; provided, however, that such Purchase Price shall be so paid pursuant to this Section 11.08 only

 The Company shall purchase from the Holder thereof, pursuant to this Section 11.08, a portion of a Security if the Principal Amount of such portion is
$1,000 or an integral multiple of $1,000 if so requested by the Holder. Provisions

Section 11.08 shall be consummated by the delivery of the consideration to be received by the Holder promptly following the later of the Purchase Date and the time of delivery of the Security.

cease to accrue on and after the Purchase Date; and 
  
 (x) the CUSIP number of the Securities. 
  
 At least
three Business Days before the Company Notice Date, the Company shall deliver an Officers’ Certificate to the Trustee specifying whether the Company desires the Trustee to give the Company Notice. 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. On or before the Company Notice Date,
the Company shall publish a notice containing substantially the same information that is required in the Company Notice in a newspaper published in the English language, customarily published each Business Day and of general circulation in The City
of New York, or publish such information on the Company’s website or through such other public medium as the Company may use at such time. 
  
 (d) Procedure upon Purchase. The Company shall deposit cash at the time and in the manner as provided in Section 11.11, sufficient to pay the
aggregate Purchase Price of all Securities to be purchased pursuant to this Section 11.08. 
  
 Section 11.09. Repurchase of Securities at Option of the Holder Upon Fundamental Change. 
  
 (a) General. If prior to the Stated Maturity there shall have occurred a Fundamental Change, Securities shall be purchased by the Company, at the
Fundamental Change Repurchase Price on a date that is 20 days after the occurrence of a Fundamental Change (the “Fundamental Change Repurchase Date”), at the option of the Holder thereof, upon: 
  
 (1) delivery to the Paying Agent by the Holder of a written
notice of purchase (a “Fundamental Change Repurchase Notice”), substantially in the form of Exhibit C hereto, at any time from the opening of business on the date of the Fundamental Change Company Notice (as

 (A) the certificate number of the Security which the Holder will deliver to be purchased; 
  
 (B) the portion of the Principal Amount of the Security
which the Holder will deliver to be purchased, which portion must be in a Principal Amount of $1,000 or integral multiples thereof; 
  
 (C) that such Security shall be purchased as of the Fundamental Change Repurchase Date pursuant to the terms and conditions specified in
the Securities and in this Indenture; and 
  
 (2)
delivery of such Security to the Paying Agent for cancellation prior to, on or after the Fundamental Change Repurchase Date (together with all necessary endorsements) at the offices of the Paying Agent, such delivery being a condition to receipt by
the Holder of the Fundamental Change Repurchase Price therefor; provided, however, that such Fundamental Change Repurchase Price shall be so paid pursuant to this Section 11.09 only if the Security so delivered to the Paying Agent
shall conform in all respects to the description thereof in the related Fundamental Change Repurchase Notice. 
  
 Notwithstanding the foregoing provisions, the Company shall not be required to repurchase the Securities of the Holders pursuant to this Section 11.09 if
the Sale Price per share of Common Stock for any five Trading Days within the period of 10 consecutive Trading Days ending immediately after the later of the Fundamental Change or the public announcement of the Fundamental Change equals or exceeds
105% of the Conversion Price of the Securities in effect on each of those five Trading Days.

received by the Holder promptly following the later of the Fundamental Change Repurchase Date and the time of delivery of the Security. 
  
 Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by

  

 69 








 
this Section 11.09(a) shall have the right to withdraw such Fundamental Change Repurchase Notice at any time prior to the close of business on the Business
Day prior to the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 11.10. 
  
 The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal

Agent for cancellation to collect payment;

 Section 11.10. Effect of Purchase Notice or Fundamental Change Repurchase
Notice. Upon receipt by the Paying Agent of the Purchase Notice or Fundamental Change Repurchase Notice specified in Section 11.08(a) or Section 
  

 71 








 
11.09(a), as applicable, the Holder of the Security in respect of which such Purchase Notice or Fundamental Change Repurchase Notice, as the case may be, was
given shall (unless such Purchase Notice or Fundamental Change Repurchase Notice is withdrawn as specified in the following two paragraphs) thereafter be entitled to receive solely the Purchase Price or Fundamental Change Repurchase Price, as the
case may be, with respect to such Security. Such Purchase Price or Fundamental Change Repurchase Price shall be paid to such Holder, subject to receipt of funds by the Paying Agent, promptly following the later of (x) the Purchase Date or the

Agent by the Holder thereof in the manner required by Section 11.08(a) or Section 11.09(a), as applicable. Securities in respect of which a Purchase Notice or Fundamental Change Repurchase Notice, as the case may be, has been given by the Holder
thereof may not be converted pursuant to Article 13 hereof on or after the date of the delivery of such Purchase Notice or Fundamental Change Repurchase Notice, as the case may be, unless such Purchase Notice or Fundamental Change Repurchase Notice,
as the case may be, has first been validly withdrawn as specified in the following two paragraphs. 
  
 A Purchase Notice or Fundamental Change Repurchase Notice, as the case may be, may be withdrawn by means of a written notice of withdrawal delivered to
the office of the Paying Agent in accordance with the procedures set forth in the Company Notice or Fundamental Change Company Notice, as the case may be, at any time prior to the close of business on the Business Day prior to the Purchase Date or
the Fundamental Change Repurchase Date, as the case may be, specifying: 
  
 (i) the Principal Amount of the Security with respect to which such notice of withdrawal is being submitted; and 
  
 (ii) the certificate number of the Security in respect of which such notice of withdrawal is being submitted; and 
  
 (iii) the Principal Amount, if any, of such Security which
remains subject to the original Purchase Notice or Fundamental Change Repurchase Notice, as the case may be, and which has been or will be delivered for purchase or repurchase by the Company. 
  
 There shall be no purchase of any Securities pursuant to Section 11.08(a) or
11.09 if there has occurred (prior to, on or after, as the case may be, the giving, by the Holders of such Securities, of the required Purchase Notice or Fundamental Change Repurchase Notice, as the case may be) and is continuing an Event of Default
(other than a default in the payment of the Purchase Price or Fundamental Change Repurchase Price, as the case may be, with respect to such Securities). 
  

 72 








 
The Paying Agent will promptly return to the respective Holders thereof any Securities (x) with respect to which a Purchase Notice or Fundamental Change
Repurchase Notice, as the case may be, has been withdrawn in compliance with this Indenture, or (y) held by it during the continuance of an Event of Default (other than a default in the payment of the Purchase Price or Fundamental Change Repurchase
Price, as the case may be, with respect to such Securities) in which case, upon such return, the Purchase Notice or Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 
  
 Section 11.11. Deposit of Purchase Price or Fundamental Change Repurchase
Price. Prior to 10:00 a.m. (local time in The City of New York) on the Business Day following the Purchase Date or the Fundamental Change Repurchase Date, as the case may be, the Company shall deposit with the Trustee or 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 herein) an amount of money (in immediately available funds if deposited on such Business Day)
sufficient to pay the Purchase Price or the Fundamental Change Repurchase Price, as the case may be, of all the Securities or portions thereof which are to be purchased as of the Purchase Date or the Fundamental Change Repurchase Date, as
applicable. The Company shall promptly notify the Trustee in writing of the amount of any deposits of cash made pursuant to this Section. 
  
 Section 11.12. Securities Purchased or Repurchased in Part. Any Security which is to be purchased or repurchased 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 which is not purchased. 
  
 Section 11.13. Covenant to Comply With Securities Laws Upon Purchase or Repurchase of Securities. In connection with
any offer to purchase or repurchase or purchase or repurchase of Securities under Section 11.08(a) or 11.09 hereof (provided that such offer or purchase or repurchase constitutes an “issuer tender offer” for purposes of Rule 13e-4 (which
term, as used herein, includes any successor provision thereto) under the Exchange Act at the time of such offer or purchase), the Company shall (i) comply with Rule 13e-4 and Rule 14e-1 under the Exchange Act, (ii) file the related Schedule TO (or
any 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

Agent shall return to the Company any cash that remains unclaimed, together with interest or dividends, if any, thereon, held by them for the payment of the Purchase Price or Fundamental Change 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 11.11 exceeds the aggregate Purchase Price or Fundamental Change Repurchase Price, as the case may be, of the Securities or portions
thereof which the Company is obligated to purchase as of the Purchase Date or Fundamental Change Repurchase Date, as the case may be, then on the Business Day following the Purchase Date or Fundamental Change Repurchase Date, as the case may be, the
Trustee or the Paying Agent, as the case may be, shall return any such excess to the Company. 
  
 ARTICLE 12 
 INTEREST PAYMENTS ON THE
SECURITIES 
  
 Section 12.01. Interest Rate.
Interest on the Securities shall accrue at an initial rate of 3.0% per annum and shall be payable on each Interest Payment Date to holders of record on the Regular Record Date immediately preceding such Interest Payment Date. Interest will be
computed on the basis of a 360-day year comprised of twelve 30-day months. Interest on the Securities shall accrue from the most recent date to which interest has been paid, or if no interest has been paid, from June 11, 2003, until the Principal
Amount is paid or duly made available for payment. 
  
 Section
12.02. Payment of Interest; Interest Rights Preserved. 
  
 (a) Interest on any Security that is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security is registered at the close of business on the Regular Record
Date for such interest at the office or agency of the Company maintained for such purpose. Each installment of interest on any Security shall be made by check mailed to the address of the Holder specified in the register of Securities, or, at the
option of the Holder, at the Corporate Trust Office, in such lawful money of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts. In the case of a permanent Global Security,
interest payable on any Interest Payment Date will be paid to the Depositary, with respect to that portion of such permanent Global Security held for its account by Cede & Co. for the purpose of permitting such party to credit the interest
received by it in respect of such permanent Global Security to the accounts of the beneficial owners thereof. 
  

 74 








 (b) Except as otherwise specified with respect to the Securities, any interest on any Security that is
payable, but is not punctually paid or duly provided for, within 30 days following any Interest Payment Date (herein called “Defaulted Interest”, which term shall include any accrued and unpaid interest that has accrued on such
defaulted amount), shall forthwith cease to be payable to the registered Holder thereof on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, as its election in each case,
as provided in clause (1) or (2) below: 
  
 (1)
The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities are registered at the close of business on a date (the “Special Record Date”) for the payment of such Defaulted Interest,
which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and the date of the proposed payment (which shall not be less than 20 days after
such notice is received by the Trustee), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements
satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as provided in this clause. Thereupon the
Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of
the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special
Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Securities at his address as it appears on the list of Securityholders maintained pursuant to this Indenture not less than 10 days prior to such Special Record Date.
Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Persons in whose names the Securities are registered at the close of
business on such Special Record Date and shall no longer be payable pursuant to the following clause (2). 
  
 (2) The Company may make payment of any Defaulted Interest on the Securities in any other lawful manner not inconsistent with the
requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment 
  

 75 








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

ARTICLE 13 
 CONVERSION

  
 Section 13.01. Right to Convert. 
  
 (a) Subject to and upon compliance with the provisions of this Indenture,
each Holder shall have the right, at its option, at any time following the Issue Date of the Securities hereunder through the close of business on the Business Day immediately prior to the date of the Stated Maturity of the Securities (except that,
with respect to any Securities or portion thereof which shall be called for redemption, such right shall terminate, except as provided in Section 13.02 or Section 11.07, at the close of business on the Business Day next preceding the date fixed for
redemption of such Securities or portion thereof unless the Company shall default in payment due upon redemption thereof) to convert the Principal Amount of any such Securities, or any portion of such Principal Amount which is $1,000 or an integral
multiple thereof at the Conversion Price then in effect, if: 
  
 (i) during any fiscal quarter (beginning with the fourth fiscal quarter of 2003) the closing Sale Price of the Company’s Common Stock for at least 20 Trading Days in the 30 Trading-Day period ending on the last
Trading Day of the immediately preceding fiscal quarter exceeds 130% of the Conversion Price of the Securities as in effect on that 30th Trading Day of that period; or 
  
 (ii) any Holder’s Security is called for redemption and such Holder surrenders such Security for
conversion at any time prior to the close of business on the Business Day prior to the Redemption Date; or 
  
 (iii) If, during any period, the Securities are rated by either Moody’s Investors Service, Inc. or Standard & Poor’s Rating
Group and the credit rating initially assigned to the Securities by either such rating agency is reduced by two or more ratings levels; or 
  
 (iv) as provided in Section 13.01(b). 
  

 76 








 (b) In addition, in the event that: 
  
 (i) (A) the Company distributes to all holders of Common Stock, rights entitling such holders to purchase
Common Stock at less than the average Sale Price of the Common Stock on the Trading Day preceding the declaration date for such distribution; or (B) the Company distributes to all holders of Common Stock the Company’s assets, debt securities or
certain rights to purchase the Company’s securities, which distribution has a per share value, as determined by the Company’s Board of Directors, exceeding 15% of the last reported Sale Price of the Common Stock on the Trading Day
preceding the declaration date for such distribution. 
  
 then, in
each case, the Company must notify, in writing, Holders of Securities of the occurrence of such an event at least 20 days prior to the Ex-Dividend Date for any such distribution. Once the Company has given such notice, Holders may surrender their
Securities for conversion at any time until the earlier of the close of business on the Business Day immediately preceding the Ex-Dividend Date or the date of announcement by the Company that the distribution will not take place; or 
  
 (ii) the Company becomes party to a consolidation, merger or
binding share exchange pursuant to which the Common Stock of the Company would be converted into cash, securities or other property, a Holder may surrender the Securities for conversion at any time from and after the date which is 15 days prior to
the anticipated effective date of the transaction until 15 days after the actual date of the transaction. If the Company becomes party to a consolidation, merger or binding share exchange pursuant to which the Common Stock of the Company would be
converted into cash, securities or other property, then at the effective time of the transaction, the right to convert the Securities into Common Stock shall be changed into a right to convert such Securities into the kind and amount of cash,
securities or other property which the Holder would have received if the Holder had converted such Securities immediately prior to the transaction. If the transaction also constitutes a Fundamental Change, the Holder shall have the rights set forth
in Section 11.09. 
  
 Section 13.02. Conversion Procedures.

  
 (a) 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 Security will be converted into shares of Common Stock at the Conversion Price therefor.

 (b) In order to exercise the conversion privilege with respect to any Securities in certificated form,
the Holder of any such Securities to be converted, in whole or in part, shall: 
  
 (i) complete and manually sign the conversion notice (the “Conversion Notice”) provided on the back of the Security and
deliver such notice to a Conversion Agent; 
  
 (ii) surrender the Security to a Conversion Agent; 
  
 (iii) furnish appropriate endorsements and transfer documents, if required; and 
  
 (iv) pay any transfer or similar tax, if required. 
  
 The date on which the Holder satisfies all of the requirements set forth in (i) through (iv) above is the “Conversion
Date.” Such notice shall also state the name or names (with address or addresses) in which the certificate or certificates for shares of Common Stock which shall be issuable on such conversion shall be issued. All such Securities
surrendered for conversion shall, unless the shares issuable on conversion are to be issued in the same name as the registration of such Securities, be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory to the
Company duly executed by, the Holder or his duly authorized attorney. 
  
 In order to exercise the conversion privilege with respect to any interest in Securities in global form, the Holder must complete the appropriate instruction form for conversion pursuant to the Depositary’s book-entry conversion
program, furnish appropriate endorsements and transfer documents if required by the Company or the Trustee or Conversion Agent, and pay the funds, if any, required by this Section 13.03 and any transfer taxes if required pursuant to Section 13.08.

  
 (c) As promptly as practicable after satisfaction of the
requirements for conversion set forth above (but in no event later than 3 Business Days after the Conversion Date), subject to compliance with any restrictions on transfer of shares issuable on conversion are to be issued in a name other than that
of the Holder (as if such transfer were a transfer of the Securities (or portion thereof) so converted), the Company shall issue and shall deliver to such Holder at the office of the Conversion Agent, a certificate or certificates for the number of
full shares of Common Stock issuable upon the conversion of such Securities or portion thereof in accordance with the provisions of this Article and a check or cash in respect of any fractional interest in respect of a share of Common Stock arising
upon such conversion, as provided in Section 13.04. In case any Securities of a denomination greater than $1,000 shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of
the Securities so surrendered, without charge to him, new Securities in 
  

 78 








 
authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Securities. 
  
 (d) Each conversion shall be deemed to have been effected as to any such
Securities (or portion thereof) on the date on which the requirements set forth above in this Section 13.02 have been satisfied as to such Securities (or portion thereof), and the person in whose name any certificate or certificates for shares of
Common Stock shall be issuable upon such conversion shall be deemed to have become on said date the Holder of record of the shares represented thereby; provided, however, that in case of any such surrender on any date when the stock
transfer books of the Company shall be closed, the person or persons in whose name the certificate or certificates for such shares are to be issued shall be deemed to have become the record Holder thereof for all purposes on the next day on which
such stock transfer books are open, but such conversion shall be at the Conversion Price in effect on the date upon which such Securities shall be surrendered. 
  

All Securities or portions thereof surrendered for conversion during the period from the close of business on the Regular Record Date for any Interest
Payment Date to the close of business on the Business Day next preceding the following Interest Payment Date shall (unless such Securities or portion thereof being converted shall have been called for redemption on a Redemption Date which occurs
during the period from the close of business on such Regular Record Date to the close of business on the Business Day next preceding the following Interest Payment Date) be accompanied by payment, in funds acceptable to the Company, of an amount
equal to the interest otherwise payable on such Interest Payment Date on the Principal Amount being converted; provided, however, that no such payment need be made if there shall exist at the time of conversion a default in the payment
of interest on the Securities. Except as provided above in this Section 13.02, no payment or other adjustment shall be made for interest accrued on any Securities converted or for dividends on any shares issued upon the conversion of such Securities
as provided in this Article. Accrued and unpaid interest and Additional Amounts, if any, will be deemed paid in full rather than canceled, extinguished or forfeited. 
  
 (e) Upon the conversion of an interest in Global Securities, the Trustee (or other Conversion Agent appointed by the
Company) shall make a notation on such Global Securities as to the reduction in the Principal Amount represented thereby. The Company shall notify the Trustee in writing of any conversions of Securities effected through any Conversion Agent other
than the Trustee. 
  
 Section 13.03. Payment upon Conversion.
Upon conversion, the Company, at its option, may choose to deliver, in lieu of its shares of Common Stock, cash or a combination of cash and shares of its Common Stock: 
  

 79 








 (a) Conversion Prior to Final Notice. In the event that the Company receives a Holder’s
Conversion Notice on or prior to the day that is 10 days prior to Stated Maturity (the “Final Notice Date”), the following procedures shall apply: 
  
 (i) if the Company chooses to satisfy all or any portion of its obligation (the “Conversion
Obligation”) in cash, it will notify the Holders through the Trustee of the dollar amount to be satisfied in cash (which must be expressed either as 100% of the Conversion Obligation or as a fixed dollar amount) at any time on or before the
date that is two Business Days following receipt of such Holder’s Conversion Notice (the “Cash Settlement Notice Period”). 
  
 (ii) If the Company timely elects to pay cash for any portion of the shares otherwise issuable to such Holder, such Holder may retract the
Conversion Notice 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 shall be made (and a Conversion
Notice shall be irrevocable) if the Company does not elect to deliver cash in lieu of shares (other than cash in lieu of fractional shares). 
  
 (iii) If the Conversion Notice has not been retracted, then settlement (in cash and/or shares) will occur on the Business Day following
the final day of the 10 Trading Day period beginning on the day after the final day of the Conversion Retraction Period (the “Cash Settlement Averaging Period”). 
  
 (iv) Settlement amounts shall be computed as follows: 
  
 (A) If the Company elects to satisfy the entire Conversion
Obligation in shares of Common Stock, it shall deliver to such Holder a number of shares equal to (i) the aggregate principal amount of the Securities to be converted divided by the Conversion Price. 
  
 (B) If the Company elects to satisfy the entire Conversion
Obligation in cash, it shall deliver to such Holder cash in an amount equal to the product of (i) the aggregate principal amount of Securities to be converted divided by the Conversion Price, multiplied by (ii) the average Sale Price of the
Company’s Common Stock during the Cash Settlement Averaging Period. 
  
 (C) If the Company elects to satisfy a fixed portion (other than 100%) of the Conversion Obligation in cash, it will deliver to such Holder such cash amount (the “Cash Amount”) 

  

 80 








 
and a number of shares of Common Stock equal to the greater of (i) zero and (ii) the excess, if any, of the number of shares of Common Stock calculated as
set forth in (A), above, over the number of shares of Common Stock equal to the sum, for each day of the Cash Settlement Averaging Period, of (x) 10% of the Cash Amount, divided by (y) the Sale Price of the Common Stock. 
  
 (b) Conversion After Final Notice. In the event that the Company shall
receive a Holder’s Conversion Notice after the Final Notice Date, the following procedures shall apply: 
  
 (i) if the Company chooses to satisfy all or any portion of the Conversion Obligation in cash, it will notify the Holders through the
Trustee of the dollar amount to be satisfied in cash (which must be expressed either as 100% of the Conversion Obligation or as a fixed dollar amount) at any time on or before the Final Notice Date. Settlement amounts will be computed and settlement
dates will be determined in the same manner as set forth in paragraph (a) above, except that the Cash Settlement Averaging Period shall be the 10 Trading Day period beginning on the day after receipt of such Holder’s Conversion Notice (or in
the event the Company receives a Holder’s Conversion Notice on the Business Day prior to the Stated Maturity, the 10 Trading Day period beginning on the day after the Stated Maturity). Settlement (in cash and/or shares) will occur on the
Business Day following the final day of such Cash Settlement Averaging Period. 
  
 Section 13.04. Cash Payments in Lieu of Fractional Shares. The Company will not issue fractional shares of Common Stock upon conversion of Securities. If multiple Securities shall be surrendered for conversion
at one time by the same Holder, the number of full shares which shall be issuable upon conversion shall be computed on the basis of the aggregate Principal Amount of the Securities (or specified portions thereof to the extent permitted hereby) so
surrendered. If any fractional share of stock would be issuable upon the conversion of any Securities, the Company shall make an adjustment and payment therefor in cash at the current market value thereof to the Holder of Securities. The current
market value of a fraction of a share of Common Stock shall be determined by multiplying the Sale Price of such Common Stock on the Trading Day before the Conversion Date by such fraction and rounding the product to the nearest whole cent.

  
 Section 13.05. Conversion Price. The Conversion Price
shall be as specified in the Security, subject to adjustment as provided in this Article 13. 
  

 81 








 Section 13.06. Adjustment of Conversion Price. The Conversion Price shall be adjusted 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, the Conversion Price 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 shall be reduced by multiplying such Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on
the date fixed for such determination and the denominator of which shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution, such reduction to become effective immediately after the
opening of business on the day following the date fixed for such determination. If any dividend or distribution of the type described in this Section 13.06(a) is declared but not so paid or made, the Conversion Price shall again be adjusted to the
Conversion Price which would then be in effect if such dividend or distribution had not been declared. 
  
 (b) In case outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Price in effect at the
opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately reduced, and conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common
Stock, the Conversion Price in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately increased, such reduction or increase, as the case may be, to become effective
immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective. 
  
 (c) In case the Company shall issue rights or warrants to all Holders of its outstanding shares of Common Stock entitling them (for a period expiring
within 60 days after the date fixed for determination of stockholders entitled to receive such rights or warrants) to subscribe for or purchase shares of Common Stock (or securities convertible into Common Stock) at a price per share (or having a
conversion price per share) less than the Current Market Price on the date fixed for determination of stockholders entitled to receive such rights or warrants, the Conversion Price shall be adjusted so that the same shall equal the price determined
by multiplying the Conversion Price in effect immediately prior to the date fixed for determination of stockholders entitled to receive such rights or warrants by a fraction, the numerator of which shall be the number of shares of Common Stock
outstanding at the close of business on the date fixed for determination of stockholders entitled to receive such rights or warrants plus the number of shares which the aggregate offering price of the total number of shares 
  

 82 








 
so offered (or the aggregate conversion price of the convertible securities so offered, which shall be determined by multiplying the number of shares of
Common Stock issuable upon conversion of such convertible securities by the conversion price per share of Common Stock pursuant to the terms of such convertible securities) would purchase at such Current Market Price, and the denominator of which
shall be the number of shares of Common Stock outstanding on the date fixed for determination of stockholders entitled to receive such rights or warrants plus the total number of additional shares of Common Stock offered for subscription or purchase
or into which convertible securities so offered are convertible. 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 fixed for determination of stockholders entitled to receive such rights or warrants. To the extent that shares of Common Stock (or securities convertible into Common Stock) are not delivered, after the expiration of such rights or warrants
the Conversion Price shall be readjusted to the Conversion Price which 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 (or the number of shares of Common Stock issuable upon conversion of convertible securities actually issued). In the event that such rights or warrants are not so issued, the Conversion Price shall again be adjusted to be the
Conversion Price which 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 Current Market Price, 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 or to be received upon exercise of such rights or warrants, the value of such consideration, if other than cash, to be determined by the Board of Directors. 
  
 (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 (other than any dividends or distributions to which Section 13.06(a) applies) or evidences of its indebtedness or assets (including securities, but excluding any rights or warrants referred to in Section 13.06(b), and
excluding any dividend or distribution (x) paid exclusively in cash or (y) referred to in Section 13.06(a)) (any of the foregoing hereinafter in this Section 13.06(d) called the “Distributed Securities”), then, in each such case,
the Conversion Price shall be reduced so that the same shall be equal to the price determined by multiplying the Conversion Price in effect on the Record Date with respect to such distribution by a fraction, the numerator of which shall be the
Current Market Price per share of the Common Stock on such Record Date less the fair market value (as determined by the Board of Directors, whose good faith determination shall be conclusive, and described in a resolution of the Board if Directors)
on the Record Date of the 
  

 83 








 
portion of the Distributed Securities so distributed applicable to one share of Common Stock and the denominator of which shall be the Current Market Price
per share of the Common Stock, such reduction to become effective immediately prior to the opening of business on the day following such Record Date. If the Board of Directors determines the fair market value of any distribution for purposes of this
Section 13.06(d) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the Current Market Price of the Common Stock. 
  
 Each share of Common Stock issued upon conversion of Securities pursuant to
this Article 13 shall be entitled to receive the appropriate number of Common Stock or preferred stock purchase rights, if any, as may be provided by the terms of any stockholder rights plan adopted by the Company (notwithstanding the occurrence of
an event causing such rights to separate from the Common Stock at or prior to the time of conversion). Any distribution of rights or warrants pursuant to a stockholder rights plan complying with the requirements set forth in the immediately
preceding sentence of this paragraph shall not constitute a distribution of rights or warrants for the purposes of Section 13.06(b) or this Section 13.06(d). 
  
 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 (a “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 13.06 (and no adjustment to the Conversion Price under this
Section 13.06 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 the Conversion Price shall be made
under this Section 13.06(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 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 the Conversion Price under this Section 13.06 was made, (1) in the case of any
such rights or warrants which shall all have been redeemed 
  

 84 








 
or repurchased without exercise by any Holders thereof, the Conversion Price 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 applicable Holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants which shall have expired or been terminated without
exercise by any Holders thereof, the Conversion Price shall be readjusted as if such rights and warrants had not been issued. 
  
 For purposes of this Section 13.06(d) and Section 13.06(a) and (b), any dividend or distribution to which this Section 13.06(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 the evidences of indebtedness, assets or shares of capital stock
other than such shares of Common Stock or rights or warrants (and any Conversion Price reduction required by this Section 13.06(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 Price reduction required by Section 13.06(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” and “the date fixed for such determination” within the meaning
of Section 13.06(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
13.06(a). 
  
 (e) In case the Company shall, by dividend or
otherwise, distribute to all Holders of its Common Stock cash (excluding any cash that is distributed upon a merger or consolidation to which Section 13.07 applies or as part of a distribution referred to in Section 13.06(d)), in an aggregate amount
that, combined together with (1) the aggregate amount of any other such distributions to all Holders of its Common Stock made exclusively in cash within the 12 months preceding the date of payment of such distribution, and in respect of which no
adjustment pursuant to this Section 13.06(e) has been made, and (2) the aggregate of any cash plus the fair market value (as determined by the Board of Directors, whose good faith determination shall be conclusive and described in a resolution of
the Board of Directors) of consideration payable in respect of any tender offer by the Company or any of its subsidiaries for all or any portion of the Common Stock concluded within the 12 months preceding the date of payment of such distribution,
and in respect of which no adjustment pursuant to Section 13.06(f) has been made, exceeds 10% of the product of the Current Market Price on the Record Date with 
  


 85 








 
respect to such distribution times the number of shares of Common Stock outstanding on such date, then, and in each such case, immediately after the close of
business on such date, the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on such Record Date by a fraction (i) the
numerator of which shall be equal to the Current Market Price on the Record Date less an amount equal to the quotient of (x) the excess of such combined amount over such 10% and (y) the number of shares of Common Stock outstanding on the Record Date
and (ii) the denominator of which shall be equal to the Current Market Price on such date; provided, however, that in the event the portion of the 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 Security holder shall have the right to receive upon conversion of a Security (or any portion thereof)
the amount of cash such Holder would have received had such Holder converted such Security (or portion thereof) immediately prior to such Record Date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall
again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared. 
  
 (f) In case a tender offer made by the Company or any of its subsidiaries for all or any portion of the Common Stock shall expire and such tender offer
(as amended upon the expiration thereof) shall require the payment to stockholders (based on the acceptance (up to any maximum specified in the terms of the tender offer) of Purchased Shares (as defined below)) of an aggregate consideration having a
fair market value (as determined by the Board of Directors, whose good faith determination shall be conclusive and described in a resolution of the Board of Directors) that combined together with (1) the aggregate of the cash plus the fair market
value (as determined by the Board of Directors, whose good faith determination shall be conclusive and described in a resolution of the Board of Directors), as of the expiration of such tender offer, of consideration payable in respect of any other
tender offers, by the Company or any of its subsidiaries for all or any portion of the Common Stock expiring within the 12 months preceding the expiration of such tender offer and in respect of which no adjustment pursuant to this Section 13.06(f)
has been made and (2) the aggregate amount of any distributions to all Holders of the Common Stock made exclusively in cash within 12 months preceding the expiration of such tender offer and in respect of which no adjustment pursuant to Section
13.06(e) has been made, exceeds 10% of the product of the Current Market Price as of the last time (the “Expiration Time”) tenders could have been made pursuant to such tender offer (as it may be amended) times the number of shares
of Common Stock outstanding (including any tendered shares) at the Expiration Time, then, and in each such case, immediately prior to the opening of business on the day after the date of the Expiration Time, the Conversion Price shall be reduced so
that the 
  

 86 








 
same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to close of business on the date of the Expiration Time
by a fraction of which the numerator shall be the number of shares of Common Stock outstanding (including any tendered shares) at the Expiration Time multiplied by the Current Market Price of the Common Stock on the Trading Day next succeeding the
Expiration Time and the denominator shall be the sum of (x) the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender offer)
of all shares validly tendered 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 Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time, such reduction (if any) 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 offer, but the Company is permanently prevented by applicable law from effecting any such
purchases or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such tender offer had not been made. If the application of this Section 13.06(f) to any tender
offer would result in an increase in the Conversion Price, no adjustment shall be made for such tender offer under this Section 13.06(f). 
  
 (g) For purposes of this Section 13.06, the following terms shall have the meaning indicated: 
  
 (i) “Current Market Price” shall, for the
purposes of any computation under Section 13.06(b), (d), (e) and (f) above relating to the current market price per share of Common Stock at a specified date, mean the average of the Sale Prices for the 10 consecutive Trading Days (as defined below)
preceding the day before the record date (or, if earlier, the Ex-Dividend Date) with respect to any distribution, issuance or other event requiring such computation. 
  
 (ii) “fair market value” shall mean the amount which a willing buyer would pay a willing
seller in an arm’s length transaction. 
  
 (iii) “Record Date” shall mean, with respect to any dividend, distribution or other transaction or event in which the Holders of Common Stock have the right to receive any cash, securities or other property or in which the
Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, 
  

 87 








 
securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise). 
  
 (h) The Company may make such reductions in the Conversion Price, in addition
to those required by Section 13.06(a), (b), (c), (d), (e) and (f) 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 Common Stock resulting from any dividend or
distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes. 
  
 To the extent permitted by applicable law, the Company from time to time may reduce the Conversion Price by any amount for any period of time if the
period is at least 20 days, the reduction is irrevocable during the period and the Board of Directors shall have made a determination that such reduction would be in the best interests of the Company, which determination shall be conclusive.
Whenever the Conversion Price is reduced pursuant to the preceding sentence, the Company shall mail to Holders of record of the Securities a notice of the reduction at least 15 days prior to the date the reduced Conversion Price takes effect, and
such notice shall state the reduced Conversion Price and the period during which it will be in effect. 
  
 (i) No adjustment in the Conversion Price shall be required unless such adjustment would require an increase or decrease of at least 1% in such price;
provided, however, that any adjustments which by reason of this Section 13.06(i) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article 13 shall be
made by the Company and shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be. No adjustment need be made for rights to purchase Common Stock pursuant to a Company plan for reinvestment of dividends or
interest. 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 the cash, assets, property or such securities. Interest will
not accrue on the cash. 
  
 (j) Whenever the Conversion Price is
adjusted as herein provided, the Company shall promptly file with the Conversion Agent an Officers’ Certificate setting forth the Conversion Price 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 the Conversion Price and may assume without inquiry that the last
Conversion Price of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Price setting forth the adjusted Conversion Price and the date on
which each adjustment becomes effective and shall mail such notice of such adjustment of the 
  

 88 








 
Conversion Price to each Holder of Securities at such Holder’s last address appearing on the list of Security holders provided for in Section 13.06 of
this Indenture, within 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 13.06 provides that an adjustment shall become effective immediately after a Record Date for an event, the Company
may defer until the occurrence of such event (i) issuing to the Holder of any Securities converted after such Record Date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the
adjustment required by such event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment and (ii) paying to such Holder any amount in cash in lieu of any fraction pursuant to Section 13.03. 

 
 (l) For purposes of this Section 13.06, 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. 
  
 Section 13.07. Effect of Reclassification, Consolidation, Merger or Sale. If any of the following events occur, namely (i) any reclassification or
change of shares of Common Stock issuable upon conversion of the Securities (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination, or any other change
for which an adjustment is provided in Section 13.06(c)), (ii) any consolidation or merger or combination to which the Company is a party other than a merger in which the Company is the continuing corporation and which does not result in any
reclassification of, or change (other than in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination) in outstanding shares of Common Stock, or (iii) any sale or conveyance of
all or substantially all of 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, 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 comply with the Trust Indenture Act of 1939 as in force at the date of
execution of such supplemental indenture) providing that such Securities shall be convertible into the kind and amount of shares of stock, securities or other property or assets (including cash) receivable upon such reclassification, change,
consolidation, merger, combination, sale or conveyance by a holder of a number of shares of Common Stock issuable upon conversion of such Securities (assuming, for such purposes, a sufficient number 
  

 89 








 
of authorized shares of Common Stock available to convert all such Securities) immediately prior to such reclassification, change, consolidation, merger,
combination, sale or conveyance, assuming such holder of Common Stock did not exercise his rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon such reclassification, change, consolidation,
merger, combination, sale or conveyance (provided that, if the kind or amount of stock, securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, 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 13.07, the kind and amount of securities, cash or other
property receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance for each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares).
Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 13. The above provisions of this Section shall similarly apply to successive
reclassifications, changes, consolidations, mergers, combinations, sales and conveyances. If this Section 13.07 applies to any event or occurrence, Section 13.07 shall not apply. 
  
 Section 13.08. Taxes on Shares Issued. The issue of stock certificates on conversions of Securities shall be made
without charge to the converting Holder for any documentary, transfer, stamp or any similar tax in respect of the issue thereof. The Company shall not, however, be required to pay any such 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 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 13.09. Reservation of Shares; Shares to be Fully Paid; Compliance with Governmental Requirements; Listing of Common Stock. 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. 
  
 Before taking any action which would cause an
adjustment reducing the Conversion Price 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 Price. 
  

 90 








 The Company covenants that all shares of Common Stock which may be issued upon conversion of Securities
shall be newly issued shares or Treasury shares, shall be duly authorized, validly issued, fully paid and non-assessable and shall be free from preemptive rights and free from any lien or adverse claim. 
  
 The Company shall use its reasonable efforts to list or cause to have quoted
any shares of Common Stock to be issued upon conversion of Securities on each national securities exchange or over-the-counter or other domestic market on which the Common Stock is then listed or quoted. 
  
 Section 13.10. 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 the Conversion Price or whether any facts exist which may require any adjustment of the Conversion Price, 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 Securities; 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 Securities for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. 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 13.06 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 13.06 or to any adjustment to be made with respect thereto, but,
subject to the provisions of Section 6.01, 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. 
  
 Section 13.11. 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 the Conversion Price pursuant
to Section 13.06; or 
  

 91 








 (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 
  
 (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 or merger 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 any of its significant subsidiaries; or 
  
 (d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company or any of its significant subsidiaries; 
  
 the Company shall cause to be filed with the Trustee and to be mailed to each Holder of
Securities at such Holder’s address appearing on the list of Securityholders provided for in Section 13.06 of this Indenture, as promptly as practicable but in any event at least 15 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 or 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, 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, 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, sale, transfer, dissolution, liquidation or winding up. 
  
 This instrument may be executed in any number of counterparts, each of which
so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument.
