reliance on an effective registration statement under the Securities Act and shall be issued initially in the form of a Global Security, which shall be deposited with the Trustee, at its Corporate Trust Office, as custodian for the depositary, The
Depository Trust Company (“DTC”, and such depositary, or any successor thereto, being hereinafter referred to as the “Depositary”), and registered in the name of its nominee, Cede & Co. (or any successor thereto), for

amount of outstanding Securities from time to time endorsed thereon and that the aggregate amount of outstanding Securities represented thereby may from time to time be reduced or increased, as appropriate, to reflect issuances, replacements,

SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE 

  
 -9-









 
DEPOSITORY TRUST COMPANY (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY), ANY
TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE
HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF THE DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY IS EXCHANGEABLE FOR SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES
DESCRIBED IN THE INDENTURE AND, UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR SECURITIES IN DEFINITIVE FORM, THIS SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE
DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY.” 

Section 2.02 Execution And Authentication. 
 (a) The aggregate principal amount of Securities which may be authenticated and delivered under this Indenture is unlimited. 
 (b) An Officer shall sign the Securities for the Company by manual or facsimile signature. Typographic and other minor errors or defects in any such facsimile signature shall not affect the validity or
enforceability of any Security that has been authenticated and delivered by the Trustee.

on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless. 
 (d) A Security shall not be valid until an authorized signatory of the Trustee by manual signature signs the certificate of authentication on the Security. The signature shall be conclusive evidence that
the Security has been authenticated under this Indenture. 
 (e) The Trustee shall authenticate and make available for delivery
Securities for original issue upon receipt of a written order or orders of the Company signed by an Officer of the Company (a “Company Order”). The Company Order shall specify the amount of Securities to be authenticated, whether such
securities will be represented by a Global Security or Certificated Securities and the date on which each original issue of Securities is to be authenticated. 

  
 -10-









 (f) The Trustee shall act as the initial authenticating agent. Thereafter, the Trustee may
appoint an authenticating agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes
authentication by such agent. An authenticating agent shall have the same rights as an Agent to deal with the Company or an Affiliate of the Company. 
 (g) The Securities shall be issuable only in registered form without coupons and only in denominations of $1,000 principal amount and any integral multiple thereof. 

Section 2.03 Registrar, Paying Agent and Conversion Agent.

exchange (each, a “Registrar”), one or more offices or agencies where Securities may be presented for payment (each, a “Paying Agent”), one or more offices or agencies where Securities may be presented for conversion (each, a
“Conversion Agent”) and one or more offices or agencies where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. One of the Registrars (the “Primary Registrar”) shall keep a
register of the Securities and of their transfer and exchange. 
 (b) The Company shall enter into an appropriate agency
agreement with any Agent not a party to this Indenture, provided that the Agent may be an Affiliate of the Trustee. The agreement shall implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee in
writing of the name and address of any Agent not a party to this Indenture. If the Company fails to maintain a Registrar, Paying Agent, Conversion Agent, or agent for service of notices and demands, or fails to give the foregoing notice, the Trustee
shall act as such. The Company or any Affiliate of the Company may act as Paying Agent (except for the purposes of Section 5.01 and Article IX). 
 (c) The Company hereby initially designates the Trustee as Paying Agent, Registrar, Securities Custodian and Conversion Agent, and designates the Corporate Trust Office of the Trustee as the office where
notices and demands to or upon the Company in respect of the Securities and this Indenture shall be served.

benefit of Holders of Securities or the Trustee all money held by the Paying Agent for the payment of principal of, or interest on, the Securities, and shall notify the Trustee in writing of any failure by the Company (or any other obligor on the
Securities) to make any such payment. If the Company or an Affiliate of the Company acts as Paying Agent, it shall, before 12:00 p.m.(noon), New York City time, on each due date of the principal of, or interest on, any Securities, segregate the
money and hold it as a separate trust 

  
 -11-

a Paying Agent, require such Paying Agent to pay forthwith to the Trustee all sums so held in trust by such Paying Agent. Upon doing so, the Paying Agent (other than the Company) shall have no further liability for the money. 

Section 2.05 Lists of Holders of Securities. 
 The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders of Securities. If the Trustee is not the Primary
Registrar, the Company shall furnish to the Trustee at least five (5) Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may
reasonably require of the names and addresses of Holders of Securities. 
 Section 2.06 Transfer And Exchange.

 (a) Subject to compliance with any applicable additional requirements contained in Section 2.12, when a Security is
presented to a Registrar with a request to register a transfer thereof or to exchange such Security for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as
requested; provided, however, that every Security presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by an assignment form and, if applicable, a transfer certificate each in the form
included in Exhibit A, and completed in a manner satisfactory to the Registrar and duly executed by the Holder thereof or its attorney duly authorized in writing. To permit registration of transfers and exchanges, upon surrender of any Security
for registration of transfer or exchange at an office or agency maintained pursuant to Section 2.03, the Company shall execute and upon receipt of a Company Order the Trustee shall authenticate Securities of a like aggregate principal amount at
the Registrar’s request. Any exchange or transfer shall be without charge, except that the Company or the Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto;
provided that this sentence shall not apply to any exchange pursuant to Section 2.10, 3.06, 3.13, 4.02(e) or 10.05.

portions thereof selected or called for redemption (except, in the case of redemption of a Security in part, the portion thereof not to be redeemed), (3) any Securities or portions thereof in respect of which a Fundamental Change Repurchase
Notice has been delivered and not withdrawn by the Holder thereof (except, in the case of the purchase of a Security in part, the portion thereof not to be purchased) or (4) any Securities or portions thereof in respect of which a Put Right
Purchase Notice has been delivered and not withdrawn by the Holder thereof (except, in the case of the purchase of a Security in part, the portion thereof not to be purchased). 

  
 -12-









 (c) All Securities issued upon any transfer or exchange of Securities shall be valid
obligations of the Company, evidencing the same debt and entitled to the same benefits under this Indenture, as the Securities surrendered upon such transfer or exchange. 
 (d) Any Registrar appointed pursuant to Section 2.03 shall provide to the Trustee such information as the Trustee may reasonably require in connection with the delivery by such Registrar of
Securities upon transfer or exchange of Securities. 
 Section 2.07 Replacement Securities. 

(a) If any mutilated Security is surrendered to the Company, a Registrar or the Trustee, or the Company, a Registrar and the Trustee
receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company, the applicable Registrar and the Trustee such security or indemnity as will be required by them to save each of them
harmless, then, in the absence of notice to the Company, such Registrar or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute, and upon delivery of a Company Order the Trustee shall authenticate and
deliver, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount, bearing a number not contemporaneously outstanding. 

(b) If any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, or is about to be
purchased or redeemed by the Company pursuant to Article III, or converted pursuant to Article IV, the Company in its discretion may, instead of issuing a new Security, pay, redeem, purchase or convert such Security, as the case may be.

 (c) Upon the issuance of any new Securities under this Section 2.07, the Company may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the reasonable fees and expenses of the Trustee or the Registrar) in connection therewith. 

(d) Every new Security issued pursuant to this Section 2.07 in lieu of any mutilated, destroyed, lost or stolen Security shall
constitute an original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and
proportionately with any and all other Securities duly issued hereunder. 
 (e) The provisions of this Section 2.07 are (to
the extent lawful) exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 

Section 2.08 Outstanding Securities. 
 (a) Securities outstanding at any time are all Securities authenticated by the Trustee, except for those canceled by it, those redeemed or purchased pursuant to Article III, those converted pursuant
to Article IV, those delivered to the Trustee for cancellation or surrendered for transfer or exchange and those described in this Section 2.08 as not outstanding. 

  
 -13-









 (b) If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding
unless the Company receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser. 
 (c) If a
Paying Agent (other than the Company or an Affiliate of the Company) holds in respect of the outstanding securities on a Redemption Date, a Fundamental Change Repurchase Date, a Put Right Purchase Date, or the Final Maturity Date money sufficient to
pay the principal of (including premium, if any) and accrued interest on Securities (or portions thereof) payable on that date, then on and after such Redemption Date, Fundamental Change Repurchase Date, Put Right Purchase Date, or Final Maturity
Date, as the case may be, such Securities (or portions thereof, as the case may be) shall cease to be outstanding and cash interest on them shall cease to accrue; provided that if such Securities are to be redeemed, notice of such redemption has
been duly given pursuant to this Indenture or provision thereof satisfactory to the Trustee has been made. 
 (d) Subject to the
restrictions contained in Section 2.09, a Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security. 
 Section 2.09 Treasury Securities. 
 In determining whether the Holders
of the required principal amount of Securities have concurred in any notice, direction, waiver or consent, securities owned by the Company or any other obligor on the Securities or by any Affiliate of the Company or of such other obligor shall be
disregarded, except that, for purposes of determining whether the Trustee shall be protected in relying on any such notice, direction, waiver or consent, only Securities which a Trust Officer of the Trustee with responsibility for this Indenture
actually knows are so owned shall be so disregarded. Securities so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to
the Securities and that the pledgee is not the Company or any other obligor on the Securities or any Affiliate of the Company or of such other obligor. 
 Section 2.10 Temporary Securities. 
 Until definitive Securities are
ready for delivery, the Company may prepare and execute, and, upon receipt of a Company Order, the Trustee shall authenticate and deliver, temporary Securities. Temporary Securities shall be substantially in the form of definitive securities but may
have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate and deliver definitive Securities in exchange for temporary Securities.

 Section 2.11 Cancellation. 
 The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar, the Paying Agent and the Conversion Agent shall forward to the Trustee or its agent any Securities

payment, 

  
 -14-









 
conversion or cancellation and shall dispose of the cancelled Securities in accordance with its customary procedures or deliver the canceled Securities to the Company. All Securities which are
redeemed, purchased or otherwise acquired by the Company or any of its Subsidiaries prior to the Final Maturity Date pursuant to Article III shall be delivered to the Trustee for cancellation, and the Company may not hold or resell such
Securities. 
 Section 2.12 Additional Transfer And Exchange Requirements. 

(a) A Global Security may not be transferred, in whole or in part, to any Person other than the Depositary or a nominee or any successor
thereof, and no such transfer to any such other Person may be registered; provided that the foregoing shall not prohibit any transfer of a Security that is issued in exchange for a Global Security but is not itself a Global Security. No transfer of
a Security to any Person shall be effective under this Indenture or the Securities unless and until such Security has been registered in the name of such Person. Notwithstanding any other provisions of this Indenture or the Securities, transfers of
a Global Security, in whole or in part, shall be made only in accordance with this Section 2.12. 
 (b) Whenever any
Security other than a Global Security is presented or surrendered for registration of transfer or in exchange for a Security registered in a name other than that of the Holder, such Security must be accompanied by a certificate in substantially the
form set forth in Exhibit A, dated the date of such surrender and signed by the Holder of such Security. The Registrar shall not be required to accept for such registration of transfer or exchange any Security not so accompanied by a properly
completed certificate. 
 As used in this Section 2.12(b), the term “transfer” encompasses any sale, pledge, transfer,
hypothecation or other disposition of any Security. 
 (c) The provisions below shall apply to Global Securities: 

(1) Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary or a nominee
thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for purposes of this Indenture. 

(2) Notwithstanding any other provisions of this Indenture or the Securities, a Global Security shall not be exchanged in
whole or in part for a Security registered, and no transfer of a Global Security in whole or in part shall be registered in the name of any Person other than the Depositary or one or more nominees thereof; provided that a Global Security may be
exchanged for securities registered in the names of any person designated by the Depositary in the event that (A) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or such
Depositary has ceased to be a “clearing agency” registered under the Exchange Act, and a successor Depositary is not appointed by the Company within 90 days after receiving such notice or becoming aware that the Depositary has ceased to be
a “clearing agency,” or (B) an Event of Default has occurred and is continuing with 

  
 -15-









 
respect to the Securities and the Depositary requests the issuance of Certificated Securities. Any Global Security exchanged pursuant to subclause (A) above shall be so exchanged in whole
and not in part, and any Global Security exchanged pursuant to subclause (B) above may be exchanged in whole or from time to time in part as directed by the Depositary. Any Security issued in exchange for a Global Security or any portion
thereof shall be a Global Security; provided further that any such Security so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Security. 

(3) Securities issued in exchange for a Global Security or any portion thereof shall be issued in definitive, fully
registered form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Security or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the
Depositary shall designate and shall bear the applicable legend provided for herein. Any Global Security to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Registrar. With regard to any Global Security to be exchanged
in part, either such Global Security shall be so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with respect to such Global Security, the principal amount thereof shall be reduced, by an amount
equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Security issuable on such exchange to or
upon the order of the Depositary or an authorized representative thereof. 
 (4) Subject to clause (6) of
this Section 2.12(c), the registered Holder 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. 
 (5) In the event of the occurrence of any of the events specified in
clause (2) of this Section 2.12(c), the Company will promptly make available to the Trustee a reasonable supply of Certificated Securities in definitive, fully registered form, without interest coupons. 

(6) Neither Agent Members nor any other Persons on whose behalf Agent Members may act shall have any rights under this
Indenture with respect to any Global Security registered in the name of the Depositary or any nominee thereof, or under any such Global Security, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and
any agent of the Company or the Trustee as the absolute owner and holder of such Global Security for all purposes whatsoever. 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 such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an
Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a holder of any Security.

 (7) At such time as all interests in a Global Security have been redeemed,
converted, cancelled or exchanged for Securities in certificated form, such Global Security shall, upon receipt thereof, be cancelled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the
Securities Custodian, subject to Section 2.11 of this Indenture. At any time prior to such cancellation, if any interest in a Global Security is redeemed, converted, canceled or exchanged for Securities in certificated form, the principal
amount of such Global Security shall, in accordance with the standing procedures and instructions existing between the Depositary and the Securities Custodian, be appropriately reduced, and an endorsement shall be made on such Global Security, by
the Trustee or the Securities Custodian, at the direction of the Trustee, to reflect such reduction. 
 Section 2.13
CUSIP Numbers. 
 The Company in issuing the Securities may use a “CUSIP” number (if then generally in use),
and, if so, the Trustee shall use the “CUSIP” number in notices of redemption or purchase as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such number either as
printed on the Securities or as contained in any notice of a redemption or purchase and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption or purchase shall not be affected by any
defect in or omission of such number. The Company will promptly notify the Trustee in writing of any change in the “CUSIP” number. 
 ARTICLE III 
 REDEMPTION AND PURCHASE 

Section 3.01 Optional Redemption. 
 (a) Prior to January 15, 2013, the Securities shall not be redeemable. The Company may, at its option, redeem the Securities for cash at the Redemption Price, in whole or in part, on any Redemption
Date (or in the case of multiple redemptions, Redemption Dates) fixed by the Company (i) from time to time on or after January 15, 2013 to, but excluding, January 15, 2015, if the Closing Price of the Common Stock equals or exceeds
150% of the Conversion Price in effect for at least 20 Trading Days during the 30 consecutive Trading Day period ending on the Trading Day immediately prior to the date the Company delivers the redemption notice specified in Section 3.03, and
(ii) on and after January 15, 2015, at any time and from time to time. The Redemption Price shall equal 100% of the principal amount of the Securities to be redeemed, plus any accrued and unpaid interest to, but excluding, the Redemption
Date; provided, however, that if the Redemption Date falls after a Regular Record Date but on or prior to the corresponding Interest Payment Date, the interest on the Securities payable on such Redemption Date will be payable to the
Holders in whose names the Securities are registered at the close of business on the applicable Regular Record Date. 

  
 -17-









 (b) If the Company elects to redeem Securities pursuant to this Section 3.01, it shall
notify the Trustee at least fifteen days prior to the date it sends the redemption notice specified in Section 3.03 to the Holders (unless a shorter notice shall be satisfactory to the Trustee), of the Redemption Date and the principal amount
of Securities to be redeemed. 
 Section 3.02 Selection Of Securities To Be Redeemed. 

(a) If less than all of the Securities are to be redeemed, unless the Applicable Procedures specify otherwise, the Trustee shall select
the Securities to be redeemed within five Business Days after it receives the notice described in Section 3.01(b). The Trustee shall make the selection from the Securities outstanding and not previously called for redemption by lot, or in its
discretion, on a pro rata basis or by another method that the Trustee considers fair and appropriate (so long as such method is not prohibited by the rules of any stock exchange or market on which the Securities are listed and the Trustee has
knowledge of such listing). Securities in denominations of $1,000 principal amount may only be redeemed in whole. The Trustee may select for redemption portions (equal to $1,000 principal amount or any integral multiple thereof) of the principal
amount of Securities that have denominations larger than $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. 
 (b) 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 (up to the amount of the redemption) to be the portion selected for redemption.
Securities which have been converted subsequent to the Trustee commencing selection of Securities to be redeemed but prior to redemption of such Securities shall be treated by the Trustee as outstanding for the purpose of such selection. 

(c) In the event of any redemption in part, the Company shall not be required to (i) issue, register the transfer of or exchange any
Security during a period beginning at the opening of business 15 days before any selection of Securities for redemption and ending at the close of business on the earliest date on which the relevant notice of redemption is deemed to have been given
to all Holders of Securities to be redeemed, or (ii) register the transfer or exchange of any Security so selected for redemption, in whole or in part, except the unredeemed portion of any security being redeemed in part. 

Section 3.03 Notice Of Redemption. 
 (a) At least 30 days but not more than 60 days before a Redemption Date, the Company shall mail or cause to be mailed a notice of redemption to each Holder of Securities to be redeemed at such
Holder’s address as it appears on the Registrar’s books. 
 (b) The notice shall identify the Securities (including
CUSIP number) to be redeemed and shall state: 
 (1) the Redemption Date; 

  
 -18-









 (2) the Redemption Price; 

(3) the then effective Conversion Rate; 

(4) the name and address of each Paying Agent and Conversion Agent; 

(5) that Securities called for redemption must be presented and surrendered to a Paying Agent to collect the Redemption
Price; 
 (6) that Holders who wish to convert Securities must surrender such Securities for conversion no later
than the close of business on the second Business Day immediately preceding the Redemption Date and must satisfy the other requirements set forth in Article IV; 

(7) that, unless the Company has failed to make the payment of such Redemption Price which is due and payable, interest
will cease to accrue on and after the Redemption Date; 
 (8) if any Security is being redeemed in part, the
portion of the principal amount of such Security to be redeemed and that, after the Redemption Date, upon presentation and surrender of such Security, a new Security or Securities in aggregate principal amount equal to the unredeemed portion thereof
will be issued; 
 (9) if Certificated Securities have been issued and fewer than all the outstanding Securities
are to be redeemed, the certificate number and the principal amounts of the particular Securities to be redeemed; and 
 (10) if such notice is provided by the Trustee, that no representation is made as to the correctness or accuracy of the CUSIP number listed in such notice. 

(c) If any of the Securities to be redeemed are in the form of a Global Security, then the Company shall modify such notice to the extent
necessary to accord with the procedures of the Depositary applicable to redemptions. At the Company’s written request, which request shall (1) be irrevocable once given and (2) set forth all relevant information required by
clauses (1) through (9) of Section 3.03(b), the Trustee shall give the notice of redemption to each Holder in the Company’s name and at the Company’s expense; provided, however, that in all cases, the text of
such notice of redemption shall be prepared by the Company; and provided further that the Company submit to the Trustee such written request, along with an Officers’ Certificate, at least five Business Days prior to the date by which such
notice of redemption must be given to the Holders in accordance with this Section 3.03 (unless a shorter period should be satisfactory to the Trustee).

 Section 3.04 Effect Of Notice Of Redemption. 

Once notice of redemption is mailed, Securities called for redemption become due and payable on the Redemption Date and at the Redemption
Price stated in the notice, except for Securities that are converted on a Conversion Date prior to the Redemption Date in accordance with the provisions of Article IV. On or after the Redemption Date and upon presentation and surrender to a
Paying Agent, Securities called for redemption shall be paid at the Redemption Price. 
 Section 3.05 Deposit Of
Redemption Price. 
 (a) Prior to 12:00 p.m. (noon), New York City time, on the Redemption Date, the Company shall
deposit with a Paying Agent (or, if the Company acts as Paying Agent, shall segregate and hold in trust) an amount of money (in immediately available funds if deposited on such Redemption Date) sufficient to pay the Redemption Price payable upon
redemption on all Securities to be redeemed on that date, other than Securities or portions thereof called for redemption on that date which 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 the cancellation of Securities or the conversion of Securities pursuant to Article IV or, if such money is then held by the Company in
trust and is not required for such purpose, it shall be discharged from the trust. 
 (b) If a Paying Agent holds, in accordance
with the terms hereof, money sufficient to pay the Redemption Price of any Security for which a notice of redemption has been tendered and not withdrawn in accordance with this Indenture then, on the Redemption Date, such Security will cease to be
outstanding, whether or not the Security is delivered to the Paying Agent, and the rights of the Holder in respect thereof shall terminate (other than the right to receive the Redemption Price as aforesaid). 

Section 3.06 Securities Redeemed In Part. 
 Upon presentation and 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 equal in principal amount to
the unredeemed portion of the Security surrendered. 
 Section 3.07 Conversion Arrangement On Call For Redemption.

 In connection with any redemption of Securities, the Company may arrange for the purchase and conversion into Common Stock of
any Securities called for redemption by an agreement with one or more investment banks or other purchasers to purchase such Securities by paying to a Paying Agent (other than the Company or any of its Affiliates) in trust for the Holders, on or
before 12:00 p.m. (noon), New York City time, on the Redemption Date, an amount that, together with any amounts deposited with such Paying Agent by the Company for the redemption of such securities, is not less than the Redemption Price.
Notwithstanding anything to the contrary contained in this Article III, 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; provided, however, that nothing in this Section 3.07 

  
 -20-









 
shall relieve the Company of its obligation to pay the Redemption Price on Securities called for redemption. If such an agreement with one or more investment banks or other purchasers is entered
into, any Securities called for redemption and not surrendered for conversion by the Holders thereof prior to the relevant Redemption Date may, at the option of the Company upon written notice to the Trustee, 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 IV) surrendered by such purchasers for conversion, all as of 12:00 p.m. (noon), New York City time, on the
Redemption Date, subject to payment of the above amount as aforesaid. The Paying Agent shall hold and pay to the Holders whose Securities are selected for redemption any such amount paid to it for purchase in the same manner as it would money
deposited with it by the Company for the redemption of Securities. Without the Paying Agent’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 Paying Agent as set forth in this Indenture, and the Company agrees to indemnify the Paying Agent 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 Paying Agent 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. 
 Section 3.08 Repurchase Of Securities At Option Of The Holder Upon a Fundamental Change. 
 (a) If a Fundamental Change occurs prior to the Final Maturity Date, each Holder of a Security shall have the right, at the option of the Holder, provided that no Default or Event of Default has occurred
and is continuing (other than a Default in the payment of the Fundamental Change Repurchase Price), to require the Company to repurchase for cash all or any portion of the Securities of such Holder equal to $1,000 principal amount (or an integral
multiple thereof) at the Fundamental Change Repurchase Price, on the date that is not less than 30 days nor more than 45 days after the date of the Fundamental Change Company Notice pursuant to subsection 3.08(b) (the “Fundamental Change
Repurchase Date”). 
 (b) On or before the 30th day after the occurrence of a Fundamental Change, the Company shall mail a
written notice of the Fundamental Change and of the resulting repurchase right to the Trustee, Paying Agent and to each Holder (and to beneficial owners to the extent and in the manner required by applicable law) (the “Fundamental Change
Company Notice”). The Fundamental Change Company Notice shall include the form of a Fundamental Change Repurchase Notice to be completed by the Holder and shall state: 

(1) the events causing such Fundamental Change; 

(2) the date of such Fundamental Change; 

(3) the last date by which the Fundamental Change Repurchase Notice must be delivered to elect the repurchase option
pursuant to this Section 3.08;

the terms of this Indenture; 
 (10) the procedures that the Holder must follow to exercise rights under this
Section 3.08; 
 (11) the procedures for withdrawing a Fundamental Change Repurchase Notice; 

(12) that, unless the Company fails to pay such Fundamental Change Repurchase Price, Securities covered by any Fundamental
Change Repurchase Notice will cease to be outstanding and interest will cease to accrue on and after the Fundamental Change Repurchase Date; and 
 (13) the CUSIP number of the Securities, provided that if such notice is provided by the Trustee, no representation is made as to the correctness or accuracy of such CUSIP number. 

At the Company’s written request, the Trustee shall give such Fundamental Change Company Notice in the Company’s name and at
the Company’s expense; provided, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company and submitted to the Trustee along with an Officers’ Certificate and written request within 20 days
after the occurrence of a Fundamental Change. If any of the Securities is in the form of a Global Security, then the Company shall modify such notice to the extent necessary to accord with the Applicable Procedures relating to the purchase of Global
Securities. 
 (c) A Holder may exercise its rights specified in Section 3.08(a) upon delivery of a written notice (which
shall be in substantially the form attached as Exhibit A under the heading “Fundamental Change Repurchase Notice” and which may be delivered by letter, overnight courier, hand delivery, facsimile transmission or in any other written

 (2) The delivery of a Security for which a Fundamental Change Repurchase Notice has been timely delivered to any Paying Agent and not validly withdrawn prior to, on or after the Fundamental Change
Repurchase Date (together with all necessary endorsements) at the office of such Paying Agent shall be a condition to the receipt by the Holder of the Fundamental Change Repurchase Price therefor. 

(3) The Company shall only be obliged to purchase, pursuant to this Section 3.08, a portion of a Security if the
principal amount of such portion is $1,000 or an integral multiple of $1,000 (provisions of this Indenture that apply to the purchase of all of a Security also apply to the purchase of such portion of such Security).

Repurchase Date (provided that the conditions in Section 3.08 have been satisfied) and (2) the time of delivery of such Security to a Paying Agent by the Holder thereof in the manner required by Section 3.08(c). Securities in respect

the manner required by Section 3.12(f). Securities in respect of which a Put Right Purchase Notice has been given by the Holder thereof may not be converted on or after the date of the delivery of such Put Right Purchase Notice, unless such Put
Right Purchase Notice has first been validly withdrawn as specified in Section 3.12(g). 
 (3) To the extent
that the aggregate amount of cash deposited by the Company pursuant to this Section 3.12(i) exceeds the aggregate Put Right Purchase Price of the Securities or portions thereof that the Company is obligated to purchase, then promptly after the
Put Right Purchase Date the Trustee or a Paying Agent, as the case may be, shall return any such excess cash to the Company, or if such money is then held by the Company in trust, it shall be discharged from the trust. 

(j) The Company shall only be obligated to purchase, pursuant to this Section 3.12, a portion of a Security if the principal amount
of such portion is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to the purchase of all of a Security also apply to the purchase of such portion of such Security.

 Section 3.13 Securities Purchased In Part 

Any Security that is to be purchased only in part shall be surrendered at the office of a Paying Agent, and promptly after the
Fundamental Change Repurchase Date or the Put Right Purchase Date, as the case may be, 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
such authorized denomination or denominations as may be requested by such Holder (which must be equal to $1,000 principal amount or any integral thereof), in aggregate principal amount equal to, and in exchange for, the portion of the principal
amount of the Security so surrendered that is not purchased. 
 Section 3.14 Compliance With Securities Laws Upon
Purchase of Securities. 
 In connection with any offer to purchase of Securities under Section 3.08 or
Section 3.12, the Company shall (a) comply with Rule 13e-4 and Rule 14e-1 (or any successor to either such Rule) and any other tender offer rules, if applicable, under the Exchange Act, (b) file the related Schedule TO
(or any successor or similar schedule, form or report) if required under the Exchange Act, and (c) otherwise comply with all federal and state securities laws in connection with such offer to purchase or purchase of Securities, all so as to
permit the rights of the Holders and obligations of the Company under Sections 3.08 through 3.12 to be exercised in the time and in the manner specified therein. To the extent that compliance with any such laws, rules and regulations would
result in a conflict with any of the terms hereof, this Indenture is hereby modified to the extent required for the Company to comply with such laws, rules and regulations, and the Company shall give prompt written notice to the Trustee of such
modifications. 
 Section 3.15 Purchase Of Securities In Open Market. 

The Company (a) shall, in accordance with Section 2.11, surrender any Security purchased by the Company pursuant to this
Article III to the Trustee for cancellation. Any securities surrendered to the Trustee for cancellation may not be reissued or resold by the Company and will be canceled promptly in accordance with Section 2.11. The Company may repurchase
Securities in open market and negotiated transactions. 
 ARTICLE IV 

CONVERSION 

Section 4.01 Conversion Privilege And Conversion Rate. 

(a) Upon compliance with the provisions of this Article IV, at the option of the Holder thereof, any Security or portion thereof
that is an integral multiple of $1,000 principal amount may be converted into fully paid and nonassessable shares (calculated as to each conversion to the nearest 1/100th of a share) of Common Stock at any time prior to the close of business on the
Business Day immediately preceding the Final Maturity Date, unless previously 

  
 -29-









 
redeemed by the Company or purchased by the Company at the Holder’s option, at the Conversion Rate in effect at such time, determined as hereinafter provided and subject to the adjustments
described below. Upon conversion of a Security, the Holder of such Security shall receive a number of shares of Common Stock equal to the product of (i) the number obtained by dividing the principal amount of the Security converted by $1,000
and (ii) the Conversion Rate in effect on the applicable Conversion Date; provided, however, that in lieu of any fractional share of Common Stock, the Company shall deliver an amount of cash equal to the product of (i) such
fraction of a share and (ii) the Closing Price of the Common Stock on the applicable Conversion Date (or, if the applicable Conversion Date is not a Trading Day, the Trading Day immediately preceding such Conversion Date). The Company shall
deliver the consideration due with respect to the conversion of any Security as soon as practicable after the applicable Conversion Date, but in no event later than five Business Days after the applicable Conversion Date. 

(b) The conversion rights pursuant to this Article IV shall commence on the initial issuance date of the Securities and expire at
the close of business on the Business Day immediately preceding the Final Maturity Date and shall be exercisable at any time, subject, in the case of conversion of any Global Security, to any Applicable Procedures. If a Security is called for
redemption or submitted or presented for purchase pursuant to Article III, such conversion right shall terminate at the close of business on the second Business Day immediately preceding the Redemption Date and on the Business Day immediately
preceding the Put Right Purchase Date or Fundamental Change Repurchase Date for such Security (unless the Company shall fail to make the Redemption Price, Put Right Purchase Price, or Fundamental Change Repurchase Price payment when due in
accordance with Article III, in which case the conversion right shall terminate at the close of business on the date such failure is cured and such Security is redeemed or purchased, as the case may be). Securities in respect of which a
Fundamental Change Repurchase Notice or a Put Right Purchase Notice, as the case may be, has been delivered may not be surrendered for conversion pursuant to this Article IV prior to a valid withdrawal of such Fundamental Change Repurchase
Notice or Put Right Purchase Notice, as the case may be, in accordance with the provisions of Article III. 
 (c)
Provisions of this Indenture that apply to conversion of all of a Security also apply to conversion of a portion of a Security. 

(d) A Holder of Securities is not entitled to any rights of a holder of Common Stock until such Holder has converted its Securities into
Common Stock. 
 (e) The Conversion Rate shall be adjusted in certain instances as provided in Section 4.01(f) and
Section 4.06. 
 (f) If prior to January 15, 2015, there shall have occurred a Fundamental Change (or an event that
would have been a Change of Control but for the existence of the 105% Trading Price Exception) (a “Make-Whole Fundamental Change”), the Company shall pay a “Make Whole Premium” to the Holders of the Securities who convert
their Securities during the period beginning on the Fundamental Change Effective Date and ending at the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date by


  
 -30-









 
increasing the Conversion Rate for such Securities. The number of additional shares of Common Stock per $1,000 principal amount of Securities constituting the Make Whole Premium shall be
determined by the Company by reference to the table below, based on the Fundamental Change Effective Date and the Stock Price of such Fundamental Change; provided that if the Stock Price or Fundamental Change Effective Date are not set forth on the
table: (i) if the actual Stock Price on the Fundamental Change Effective Date is between two Stock Prices on the table or the actual Fundamental Change Effective Date is between two Fundamental Change Effective Dates on the table, the Make
Whole Premium will be determined by a straight-line interpolation between the Make Whole Premiums set forth for the two Stock Prices and the two Fundamental Change Effective Dates on the table based on a 365-day year, as applicable, (ii) if the
Stock Price on the Fundamental Change Effective Date exceeds $15.00 per share, subject to adjustment as set forth herein, no Make Whole Premium will be paid, and (iii) if the Stock Price on the Fundamental Change Effective Date is less than
$5.00 per share, subject to adjustment as set forth herein, no Make Whole Premium will be paid. If Holders of the Common Stock receive only cash in the Fundamental Change, the Stock Price shall be the cash amount paid per share of the Common Stock
in connection with the Fundamental Change. Otherwise, the Stock Price shall be equal to the average Closing Prices of the Common Stock for each of the 10 Trading Days immediately preceding, but not including, the applicable Fundamental Change
Effective Date.

 The Stock Prices set
forth in the first column of the table above will be adjusted as of any date on which the Conversion Rate of the Securities is adjusted. The adjusted Stock Prices will equal the Stock Prices applicable immediately prior to such adjustment multiplied
by a fraction, the numerator of which is the Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of additional shares set forth
in the table above will be adjusted in the same manner as the Conversion Rate as set forth in Section 4.06 hereof, other than as a result of an adjustment of the Conversion Rate by adding the Make Whole Premium as described above. 

  
 -31-









 Notwithstanding the foregoing paragraph, in no event will the total number of shares of
Common Stock issuable upon conversion of a Security exceed 116.2790 per $1,000 principal amount, other than on account of proportional adjustments to the Conversion Rate in the manner set forth in clauses (1) and (2) of
Section 4.06(a) hereof, unless the Company obtains shareholder approval of the increase in the Conversion Rate; provided, however, that the Company shall not undertake a Make-Whole Fundamental Change without first obtaining
shareholder approval for the increase in the applicable Conversion Rate provided for in the table above. 
 The additional
shares of Common Stock delivered to satisfy the Company’s obligations to Holders that convert their Securities in connection with a Make-Whole Fundamental Change and cash in lieu of fractional shares will be delivered by the Company upon the
later of the settlement date for the conversion and promptly following the Fundamental Change Effective Date or the effective date of such other event. 
 Promptly upon the occurrence of any Make-Whole Fundamental Change, the Company shall deliver notice to each Holder and the Trustee, which notice will state that a Make-Whole Fundamental Change has
occurred and include the Make-Whole Premium, if any. Simultaneously with delivering such notice, the Company shall publish the information contained in such notice on its website. 

(g) By delivering the number of shares of Common Stock issuable on conversion and cash in lieu of fractional shares to the Trustee, the
Company will be deemed to have satisfied its obligation to pay the principal amount of the Securities so converted and, except as otherwise provided in Section 4.02(c), its obligation to pay accrued and unpaid interest attributable to the
period from the most recent Interest Payment Date through the Conversion Date (which amount will be deemed paid in full rather than cancelled, extinguished or forfeited). 
 Section 4.02 Conversion Procedure. 
 (a) To convert a Security, a
Holder must (1) complete and manually sign the conversion notice on the back of the Security and deliver such notice to a Conversion Agent, (2) surrender the Security to a Conversion Agent, (3) furnish appropriate endorsements and
transfer documents if required by a Registrar or a Conversion Agent, (4) pay all transfer or similar taxes, if required pursuant to Section 4.04, and (5) pay funds equal to the interest payable on the Interest Payment Date immediately
following the Conversion Date, if required pursuant to Section 4.02(c). The date on which the Holder satisfies all of those requirements is the “Conversion Date.” Upon the conversion of a Security, the Company will deliver the shares
of Common Stock and cash in lieu of fractional shares as promptly as practicable after the Conversion Date, but in no event later than five Business Days after the Conversion Date. Anything herein to the contrary notwithstanding, in the case of
Global Securities, conversion notices may be delivered and such Securities may be surrendered for conversion in accordance with the Applicable Procedures as in effect from time to time. 

(b) The person in whose name the shares of Common Stock are issuable upon conversion shall be deemed to be a holder of record of such
Common Stock on the close of business on the Conversion Date; provided, however, that no surrender of a Security on any 

  
 -32-









 
Conversion Date when the stock transfer books of the Company shall be closed shall be effective to constitute the person or persons entitled to receive the shares of Common Stock upon conversion
as the record holder or holders of such shares of Common Stock on such date, but such surrender shall be effective to constitute the person or persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all
purposes at the close of business on the next succeeding day on which such stock transfer books are open; provided further that such conversion shall be at the applicable Conversion Rate as if the stock transfer books of the Company had not been
closed. Upon conversion of a Security, such person shall no longer be a Holder of such Security. Except as set forth in this Indenture, no payment or adjustment will be made for dividends or distributions declared or made on shares of Common Stock
issued upon conversion of a Security prior to the issuance of such shares. 
 (c) Holders of Securities surrendered for
conversion (in whole or in part) during the period from the close of business on any Regular Record Date to the opening of business on the next succeeding Interest Payment Date will receive the semi-annual interest payable on such Securities on the
corresponding Interest Payment Date notwithstanding the conversion. Upon surrender of any such Securities for conversion, such Securities shall also be accompanied by payment in funds acceptable to the Company of an amount equal to the interest
payable on such corresponding Interest Payment Date, except to the extent of any overdue interest that is due at the time of conversion, unless (i) such Securities are converted after the close of business on the Regular Record Date immediately
preceding the Stated Maturity Date, (ii) the Company has specified a Redemption Date that is after such Regular Record Date and on or prior to such Interest Payment Date and the Holder surrenders the Securities for conversion after the close of
business on such Regular Record Date and on or prior to the close of business on the second Business Day prior to such Redemption Date or (iii) if the Company has specified a Fundamental Change Repurchase Date that is after such Regular Record
Date and on or prior to such Interest Payment Date and the Holder surrenders the Securities for conversion after the close of business on such Regular Record Date and prior to the open of business on such Fundamental Change Repurchase Date, in which
cases no such payment will be required. Except as otherwise provided in this Section 4.02(c), no payment or adjustment will be made for accrued interest on a converted Security. 

(d) Subject to Section 4.02(c), nothing in this Section shall affect the right of a Holder in whose name any Security is
registered at the close of business on a Regular Record Date to receive the interest payable on such Security on the related Interest Payment Date in accordance with the terms of this Indenture and the Securities. If a Holder converts more than one
Security at the same time, the number of shares of Common Stock issuable upon the conversion (and the amount of any cash in lieu of fractional shares pursuant to Section 4.03) shall be based on the aggregate principal amount of all Securities
so converted. 
 (e) In the case of any Security which is converted in part only, upon such conversion the Company shall execute
and the Trustee shall authenticate and deliver to the Holder thereof, without service charge, a new Security or Securities of authorized denominations in an aggregate principal amount equal to, and in exchange for, the unconverted portion of the
principal amount of such Security. A Security may be converted in part, but only if the principal amount of such part is an integral multiple of $1,000 and the principal amount of such Security to remain outstanding after such conversion is equal to
$1,000 or any integral multiple of $1,000 in excess thereof. 

  
 -33-









 Section 4.03 Fractional Shares. 

The Company will not issue fractional shares of Common Stock upon conversion of Securities. If more than one Security shall be
surrendered for conversion at one time by the same Holder, the number of full shares that 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. In lieu of any fractional shares, the Company will pay an amount in cash equal to the product of (i) such fraction of a share and (ii) the Closing Price of the Common Stock on the applicable
Conversion Date (or, if the applicable Conversion Date is not a Trading Day, the Trading Day immediately preceding such Conversion Date). 
 Section 4.04 Taxes On Conversion. 
 If a Holder converts a Security,
the Holder shall pay any transfer, stamp or similar taxes or duties related to the issue or delivery of shares of Common Stock upon such conversion. The Holder shall also pay any such tax with respect to cash received in lieu of fractional shares.
In addition, the Holder shall pay any such tax which is due because the Holder requests the shares to be issued in a name other than the Holder’s name. The Conversion Agent may refuse to deliver the certificate representing the Common Stock
being issued in a name other than the Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax which will be due because the shares are to be issued in a name other than the Holder’s name. Nothing herein shall
preclude any tax withholding required by law or regulation. 
 Section 4.05 Company To Provide Stock. 

(a) The Company shall, prior to issuance of any Securities hereunder, and from time to time as may be necessary, reserve, out of its
authorized but unissued Common Stock, a sufficient number of shares of Common Stock to permit the conversion of all outstanding Securities into shares of Common Stock. 
 (b) All shares of Common Stock delivered upon conversion of the Securities shall be newly issued shares, shall be duly authorized, validly issued, fully paid and nonassessable and shall be free from
preemptive or similar rights and free of any lien or adverse claim as the result of any action by the Company. 
 (c) The
Company will endeavor promptly to comply with all federal and state securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Securities. 

  
 -34-









 Section 4.06 Adjustment Of Conversion Rate. 

(a) The Conversion Rate shall be adjusted from time to time by the Company as follows: 

(1) If the Company shall pay a dividend or make a distribution to all holders of outstanding Common Stock in shares of
Common Stock, the Conversion Rate in effect immediately prior to the record date for the determination of shareholders entitled to receive such dividend or other distribution shall be increased so that the same shall equal the rate determined by
multiplying the Conversion Rate in effect immediately prior to such record date by a fraction of which the numerator of shall be the sum of the number of shares of Common Stock outstanding at the close of business on such record date plus the total
number of shares of Common Stock constituting such dividend or other distribution and of which the denominator shall be the number of shares of Common Stock outstanding at the close of business on such record date. Such adjustment shall be made
successively whenever any such dividend or distribution is made and shall become effective immediately after such record date. For the purpose of this clause (1), the number of shares of Common Stock at any time outstanding shall not include
shares held in the treasury of the Company. The Company will not pay any dividend or make any distribution on Common Stock held in the treasury of the Company. If any dividend or distribution of the type described in this clause is declared but not
so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 

(2) If the Company shall subdivide its outstanding Common Stock into a greater number of shares, or combine its
outstanding Common Stock into a smaller number of shares, the Conversion Rate in effect immediately prior to the day upon which such subdivision or combination becomes effective shall be, in the case of a subdivision of Common Stock, proportionately
increased and, in the case of a combination of Common Stock, proportionately reduced. Such adjustment shall be made successively whenever any such subdivision or combination of the Common Stock occurs and shall become effective immediately after the
date upon which such subdivision or combination becomes effective. 
 (3) If the Company shall issue rights or
warrants to all holders of its outstanding Common Stock entitling them (for a period expiring within 45 days after such issuance) 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 per share of Common Stock (as determined in accordance with clause (9) of this Section 4.06(a)) on the record date for the determination of shareholders entitled
to receive such rights or warrants, the Conversion Rate in effect immediately prior thereto shall be adjusted so that the same shall equal the rate determined by 

  
 -35-









 
multiplying the Conversion Rate in effect immediately prior to such record date by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of
business on such record date plus the number of additional shares of Common Stock that such rights or warrants entitle holders thereof to subscribe for or purchase (or into which such convertible securities are convertible) and of which the
denominator shall be the number of shares of Common Stock outstanding at the close of business on such record date plus the number of shares which the aggregate offering price of the total number of shares of Common Stock so offered for subscription
or purchase (or the aggregate conversion price of the convertible securities so offered for subscription or purchase, 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 the Current Market Price per share of Common Stock on such record date. Such adjustment shall be made successively
whenever any such rights or warrants (or convertible securities) are issued, and shall become effective immediately after such record date. 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 Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of
only the number of shares of Common Stock (or securities convertible into Common Stock) actually delivered. If such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in
effect if the record date for the determination of shareholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the shareholders to subscribe for or purchase shares of Common
Stock at a price less than the Current Market Price per share of Common Stock and in determining the aggregate offering price of the total number of shares of Common Stock so offered, there shall be taken into account any consideration received by
the Company for such rights or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. 

(4) If the Company shall make a dividend or other distribution to all holders of its Common Stock of Capital Stock, other
than Common Stock, or evidences of indebtedness or other assets of the Company (excluding (x) any issuance of rights or warrants for which an adjustment was made pursuant to Section 4.06(a)(3), (y) dividends or distributions in
connection with a reclassification, change, consolidation, merger, combination, liquidation, dissolution, winding up, sale or conveyance resulting in a change in the conversion consideration, or pursuant to any shareholder rights plan or
(z) any dividend or distribution paid exclusively in cash for which an adjustment was made pursuant to Section 4.06(a)(6)) (the “Distributed Securities”), then in each such case (unless the Company distributes such Distributed
Securities for distribution to the Holders of Securities on such dividend or distribution date as if 

  
 -36-









 
each Holder had converted such Security into Common Stock immediately prior to the record date with respect to such distribution) the Conversion Rate in effect immediately prior to the record
date fixed for the determination of shareholders entitled to receive such dividend or distribution shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to such record date
by a fraction of which the numerator shall be the Current Market Price per share of the Common Stock on such record date and of which the denominator shall be Current Market Price per share on such record date less the fair market value (as
determined in good faith by the Board of Directors, whose determination shall be conclusive evidence of such fair market value and which shall be evidenced by an Officers’ Certificate delivered to the Trustee) on such record date of the portion
of the Distributed Securities so distributed applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding at the close of business on such record date). Such adjustment shall be made
successively whenever any such distribution is made and shall become effective immediately after the record date for the determination of shareholders entitled to receive such distribution. In the event that such dividend or distribution is not so
paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 

If the fair market value (as so determined) of the portion of the Distributed Securities so distributed applicable to one
share of Common Stock is equal to or greater than the Current Market Price per share of the Common Stock on such record date, in lieu of the foregoing adjustment, adequate provision shall be made so that each holder of a Security shall have the
right to receive upon conversion the amount of Distributed Securities so distributed that such Holder would have received had such Holder converted each Security on such record date. If the Board of Directors determines the fair market value of any
distribution for purposes of this Section 4.06(a)(4) 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. 
 Notwithstanding the foregoing, if the securities distributed by the Company to all
holders of its Common Stock consist of Capital Stock of, or similar equity interests in, a Subsidiary or other business unit of the Company (the “Spinoff Securities”), the Conversion Rate shall be adjusted, unless the Company makes an
equivalent distribution to the Holders of the Securities, so that the same shall be equal to the rate determined by multiplying the applicable Conversion Rate in effect on and after the record date fixed for the determination of shareholders
entitled to receive such distribution by a fraction, the numerator of which shall be the sum of (A) the average Closing Price of one share of Common Stock over the ten consecutive Trading Day period (the “Spinoff Valuation Period”)
commencing on and including the fifth Trading Day after the date on which ex-dividend trading commences for such distribution on the NASDAQ 

  
 -37-









 
Global Select Market or such other U.S. national or regional exchange or market on which the Common Stock is then listed or quoted and (B) the average of the Closing Prices over the Spinoff
Valuation Period of the Spinoff Securities multiplied by the number of Spinoff Securities distributed in respect of one share of Common Stock and the denominator of which shall be the average Closing Price of one share of Common Stock over the
Spinoff Valuation Period, such adjustment to become effective immediately prior to the opening of business on the fifteenth Trading Day after the date on which ex-dividend trading commences; provided, however, that the Company may in
lieu of the foregoing adjustment elect to make adequate provision so that each Holder of Securities shall have the right to receive upon conversion thereof the amount of such Spinoff Securities that such Holder of Securities would have received if
such Securities had been converted on the record date with respect to such distribution. 
 (5) With respect to
any rights, rights certificates or warrants (the “Rights”) that may be issued or distributed pursuant to any rights plan (including any rights plan that the Company implements after the date of this Indenture, a “Rights Plan”),
in lieu of any adjustment required by any other provision of this Section 4.06, upon conversion of the Securities into Common Stock, to the extent that such Rights Plan is in effect upon such conversion, the Holders of Securities will receive,
with respect to the shares of Common Stock issued upon conversion, the Rights described therein (whether or not the Rights have separated from the Common Stock at the time of conversion), subject to the limitations set forth in and in accordance
with any such Rights Plan; provided that if, at the time of conversion, however, the Rights have separated from the shares of Common Stock in accordance with the provisions of the Rights Plan so that Holders would not be entitled to receive any
rights in respect of the shares of Common Stock issuable upon conversion of the Securities as a result of the timing of the Conversion Date, the Conversion Rate will be adjusted as if the Company distributed to all holders of Common Stock
Distributed Securities as provided in the first paragraph of clause (4) of this Section 4.06(a), subject to appropriate readjustment in the event of the expiration, termination, repurchase or redemption of the Rights. Any distribution of
rights, rights certificates or warrants pursuant to a Rights Plan complying with the requirements set forth in the immediately preceding sentence of this paragraph shall not constitute a distribution of rights, rights certificates or warrants
pursuant to this Section 4.06(a). Other than as specified in this clause (5) of this Section 4.06(a), there will not be any adjustment to the Conversion Rate as the result of the issuance of any Rights, the distribution of separate
certificates representing such Rights, the exercise or redemption of such Rights in accordance with any Rights Plan or the termination or invalidation of any Rights. 

(6) If the Company shall, by dividend or otherwise, at any time distribute (a “Triggering Distribution”) to all
holders of its Common Stock a payment consisting exclusively of cash (excluding any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company,

whether voluntary or involuntary) the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying such Conversion Rate in effect immediately prior to the
close of business on the record date for such Triggering Distribution (a “Determination Date”) by a fraction of which the numerator shall be such Current Market Price per share of the Common Stock on the Determination Date and the
denominator of which shall be the Current Market Price per share of the Common Stock on the Determination Date less the amount of such cash dividend or distribution applicable to one share of Common Stock (determined on the basis of the number of
shares of Common Stock outstanding at the close of business on the Determination Date), such increase to become effective immediately prior to the opening of business on the day following the date on which the Triggering Distribution is paid. If the
amount of cash dividend or distribution applicable to one share of Common Stock is equal to or greater than the Current Market Price per share of the Common Stock on the Determination Date, in lieu of the foregoing adjustment, adequate provision
shall be made so that each Holder of a Security shall have the right to receive upon conversion the amount of cash so distributed that such Holder would have received had such Holder converted each Security on such Determination Date. In the event
that such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such divided or distribution had not been declared. 

(7) If any tender offer made by the Company or any of its Subsidiaries for all or any portion of Common Stock shall
expire, then, if the tender offer shall require the payment to shareholders of consideration per share of Common Stock having a fair market value (determined as provided below) that exceeds the average of the Closing Price per share of Common Stock
on the Trading Day next succeeding the last date (the “Expiration Date”) tenders could have been made pursuant to such tender offer (as it may be amended) (the last time at which such tenders could have been made on the Expiration Date is
hereinafter sometimes called the “Expiration Time”), the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the close of business on the
Expiration Date by a fraction of which the numerator shall be the sum of (A) the fair market value of the aggregate consideration (the fair market value as determined in good faith by the Board of Directors, whose determination shall be
conclusive evidence of such fair market value and which shall be evidenced by an Officers’ Certificate delivered to the Trustee) payable to shareholders 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 (B) the product of the number of shares of Common Stock
outstanding (less any Purchased Shares and excluding any shares held in the treasury of the Company) at the Expiration Time and the Closing Price per share of Common Stock on the Trading Day next succeeding the Expiration Date and the denominator of
which shall be the product of the number of shares of Common Stock outstanding (including Purchased 

  
 -39-









 
Shares but excluding any shares held in the treasury of the Company) at the Expiration Time multiplied by the Closing Price per share of the Common Stock on the Trading Day next succeeding the
Expiration Date, such increase to become effective immediately prior to the opening of business on the day following the Expiration Date. 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 or all such purchases or any or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate which would have been in effect based upon
the number of shares actually purchased, if any. If the application of this clause (7) of Section 4.06(a) to any tender offer would result in a decrease in the Conversion Rate, no adjustment shall be made for such tender offer under this
clause (7). 
 (8) For purposes of this Section 4.06, the term “tender offer” shall mean and
include both tender offers and exchange offers, all references to “purchases” of shares in tender offers (and all similar references) shall mean and include both the purchase of shares in tender offers and the acquisition of shares
pursuant to exchange offers, and all references to “tendered shares” (and all similar references) shall mean and include shares tendered in both tender offers and exchange offers. 

(9) For purposes of any computation under this Section 4.06, “Current Market Price” shall mean the average
of the daily Closing Prices per share of Common Stock for each of the ten consecutive Trading Days immediately prior to the date in question; provided, however, that if 

(A) the “ex” date (as hereinafter defined) for any event (other than the issuance or distribution requiring
such computation) that requires an adjustment to the Conversion Rate pursuant to Section 4.06(a) (1), (2), (3), (4), (5), (6) or (7) occurs during such ten consecutive Trading Days, the Closing Price for each Trading Day prior to the
“ex” date for such other event shall be adjusted by dividing such Closing Price by the same fraction by which the Conversion Rate is so required to be adjusted as a result of such other event; 

(B) the “ex” date for any event (other than the issuance or distribution requiring such computation) that
requires an adjustment to the Conversion Rate pursuant to Section 4.06(a) (1), (2), (3), (4), (5), (6) or (7) occurs on or after the “ex” date for the issuance or distribution requiring such computation and prior to the day
in question, the Closing Price for each Trading Day on and after the “ex” date for such other event shall be adjusted by dividing such Closing Price by the reciprocal of the fraction by which the Conversion Rate is so required to be
adjusted as a result of such other event; and 

  
 -40-









 (C) the “ex” date for the issuance or distribution requiring such
computation is prior to the day in question, after taking into account any adjustment required pursuant to the immediately preceding clause (A) or (B) of this Section 4.06(a)(9), the Closing Price for each Trading Day on or after such
“ex” date shall be adjusted by adding thereto the amount of any cash and the fair market value (as determined in good faith by the Board of Directors in a manner consistent with any determination of such value for purposes of
Section 4.06(a)(4) or (7), whose determination shall be conclusive and set forth in a Board Resolution) of the evidences of indebtedness, shares of capital stock or assets being distributed applicable to one share of Common Stock as of the
close of business on the day before such “ex” date. 
 For purposes of any computation under Section 4.06(a)(7),
if the “ex” date for any event (other than the tender offer that is the subject of the adjustment pursuant to Section 4.06(a)(7)) that requires an adjustment to the Conversion Rate pursuant to Section 4.06(a)(1), (2), (3), (4),
(5) or (6) occurs on the date of the Expiration Time for the tender or exchange offer requiring such computation or on the Trading Day next following the Expiration Time, the Closing Price for each Trading Day on and after the
“ex” date for such other event shall be adjusted by dividing such Closing Price by the reciprocal of the fraction by which the Conversion Rate is so required to be adjusted as a result of such other event. For purposes of this
Section 4.09(a) the term “ex” date, when used: 
 (A) with respect to any issuance or
distribution, means the first date on which the Common Stock trades regular way on the relevant exchange or in the relevant market from which the Closing Price was obtained without the right to receive such issuance or distribution; 

(B) with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common
Stock trades regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective, and 
 (C) with respect to any tender or exchange offer, means the first date on which the Common Stock trades regular way on such exchange or in such market after the Expiration Time of such offer. 

Notwithstanding the foregoing, whenever successive adjustments to the Conversion Rate are called for pursuant to this Section 4.06,
such adjustments shall be made to the Current Market Price as may be necessary or appropriate to effectuate the intent of this Section 4.06 and to avoid unjust or inequitable results as determined in good faith by the Board of Directors.

 (b) In any case in which this Section 4.06 shall require that an adjustment be made following a record date, a
Determination Date or Expiration Date, as the case may be, 

  
 -41-









 
established for the purposes specified in this Section 4.06, the Company may elect to defer (but only until five Business Days following the filing by the Company with the Trustee of the
certificate described in Section 4.08) issuing to the Holder of any Security converted after such record date, Determination Date or Expiration Date the shares of Common Stock and other Capital Stock of the Company issuable upon such conversion
over and above the shares of Common Stock and other Capital Stock of the Company (or other cash, property or securities, as applicable) issuable upon such conversion only on the basis of the Conversion Rate prior to adjustment; and, in lieu of any
cash, property or securities the issuance of which is so deferred, the Company shall issue or cause its transfer agents to issue due bills or other appropriate evidence prepared by the Company of the right to receive such cash, property or
securities. If any distribution in respect of which an adjustment to the Conversion Rate is required to be made as of the record date, Determination Date or Expiration Date therefore is not thereafter made or paid by the Company for any reason, the
Conversion Rate shall be readjusted to the Conversion Rate which would then be in effect if such record date had not been fixed or such record date, Determination Date or Expiration Date had not occurred. 

(c) For purposes of this Section 4.06, “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 or converted into any combination of cash, securities
or other property, the date fixed for determination of shareholders entitled to receive such cash, security or other property (whether or not such date is fixed by the Board of Directors or by statute, contract or otherwise). 

(d) If one or more event occurs requiring an adjustment be made to the Conversion Rate for a particular period, adjustments to the
Conversion Rate shall be determined by the Company’s Board of Directors to reflect the combined impact of such Conversion Rate adjustment events, as set out in this Section 4.06, during such period. 

Section 4.07 No Adjustment 
 (a) No adjustment in the Conversion Rate shall be required if Holders may participate in the transactions set forth in Section 4.06 above (to the same extent as if the Securities had been converted
into Common Stock immediately prior to such transactions) without converting the Securities held by such Holders. 
 (b) No
adjustment in the Conversion Rate shall be required unless such adjustment would require an increase or decrease of at least 1% in the Conversion Rate as last adjusted; provided, however, that any adjustments which would be required to
be made but for this Section 4.07(b) shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article IV shall be made to the nearest cent or to the nearest one-ten thousandth of a share, as
the case may be, with one half cent and 0.00005 of a share, respectively, being rounded upward. 

  
 -42-









 (c) No adjustment in the Conversion Rate shall be required for issuances of Common Stock
pursuant to a Company plan for reinvestment of dividends or interest or for a change in the par value or a change to no par value of the Common Stock. 
 (d) To the extent that the Securities become convertible into the right to receive cash, no adjustment need be made thereafter as to the cash. 

(e) Notwithstanding anything to the contrary provided in Section 4.06, in no event shall the Conversion Rate as adjusted in
accordance with Section 4.06 exceed 116.2790 per $1,000 principal amount, other than on account of proportional adjustments to the Conversion Rate in the manner set forth in clauses (1) and (2) of Section 4.06(a), unless the
Company obtains shareholder approval of the increase in the Conversion Rate; provided, however, that the Company shall not undertake any action described in clauses (3), (4), (5), (6) or (7) of Section 4.06(a) above
without first obtaining shareholder approval for the increase in the applicable Conversion Rate that would otherwise be required as a result of such action. 
 Section 4.08 Notice of Adjustment. 
 Whenever the Conversion Rate is
required to be adjusted pursuant to this Indenture, the Company shall promptly mail to Holders a notice of the adjustment and file with the Trustee an Officers’ Certificate briefly stating the facts requiring the adjustment and the manner of
computing it. Failure to mail such notice or any defect therein shall not affect the validity of any such adjustment. Unless and until the Trustee shall receive an Officers’ Certificate setting forth an adjustment of the Conversion Rate, the
Trustee may assume without inquiry that the Conversion Rate has not been adjusted and that the last Conversion Rate of which it has knowledge remains in effect. 
 Section 4.09 Notice of Certain Transactions. 
 In the event that there
is a dissolution or liquidation of the Company, the Company shall mail to Holders and file with the Trustee a notice stating the proposed effective date. The Company shall mail such notice at least 10 days before such proposed effective date.
Failure to mail such notice or any defect therein shall not affect the validity of any transaction referred to in this Section 4.09. 
 Section 4.10 Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale. 
 If any of following events occur (each, a “Business Combination”): 
 (1) any recapitalization, reclassification or change of the Common Stock, other than changes resulting from a subdivision or a combination, 

(2) a consolidation, merger or combination involving the Company, 

  
 -43-









 (3) a sale, conveyance or lease to another corporation of all or
substantially all of the property and assets of the Company, other than one or more of the Company’s subsidiaries, or 
 (4) any statutory share exchange, 
 in each case as a result of which holders of Common Stock are
entitled to receive stock, other securities, other property or assets (including cash or any combination thereof) with respect to or in exchange for Common Stock, the Company or the successor or purchasing corporation, as the case may be, shall
execute with the Trustee a supplemental indenture (which shall comply with the TIA as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) providing that the Holders of the
Securities then outstanding will be entitled thereafter to convert such Securities into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) which they would have owned or
been entitled to receive upon such Business Combination had such Securities been converted into Common Stock immediately prior to such Business Combination, except that such Holders will not receive the Make Whole Premium if such Holder does not
convert its Securities “in connection with” the relevant Make-Whole Fundamental Change. A conversion of the Securities by a Holder will be deemed for these purposes to be “in connection with” a Make-Whole Fundamental Change if
the notice of such conversion is provided in compliance with Section 4.02(a) to the Conversion Agent on or subsequent to the Fundamental Change Effective Date but before the close of business on the Business Day immediately preceding the
related Fundamental Change Repurchase Date. In the event holders of Common Stock have the opportunity to elect the form of consideration to be received in such Business Combination, the Company shall make adequate provision whereby the Holders of
the Securities shall have a reasonable opportunity to determine the form of consideration into which all of the Securities, treated as a single class, shall be convertible from and after the effective date of such Business Combination. Such
determination shall be (i) based on the weighted average of elections made by Holders of the Securities who participate in such determination, (ii) subject to any limitations to which all of the holders of the Common Stock are subject,
such as pro-rata reductions applicable to any portion of the consideration payable in such Business Combination and (iii) conducted in such a manner as to be completed by the date which is the earliest of (a) the deadline for elections to
be made by shareholders of the Company, and (b) two Trading Days prior to the anticipated effective date of the Business Combination. The Company shall provide notice of the opportunity to determine the form of such consideration, as well as
notice of the determination made by Holders of the Securities (and the weighted average of elections), by posting such notice with DTC and providing a copy of such notice to the Trustee. In the event the effective date of the Business Combination is
delayed beyond the initially anticipated effective date, Holders of the Securities shall be given the opportunity to make subsequent similar determinations in regard to such delayed effective date. The Company may not become a party to any such
transaction unless its terms are consistent with this Section 4.10. 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 IV. If,
in the case of any such Business Combination, the stock or other securities and assets receivable thereupon by a holder of shares of Common Stock includes shares of stock or other securities and assets of a corporation other than the successor or
purchasing corporation, as the case may be, in such 

  
 -44-









 
Business Combination, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the
Securities as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent practicable the provisions providing for the repurchase rights set forth in Article III hereof. Notwithstanding
anything contained in this Section, and for the avoidance of doubt, this Section shall not affect the right of a Holder to convert its Securities into shares of Common Stock prior to the effective date of the Business Combination. 

Section 4.11 Trustee’s Disclaimer. 
 (a) The Trustee shall have no duty to determine when an adjustment under this Article IV should be made, how it should be made or what such adjustment should be, but may accept as conclusive evidence
of that fact or the correctness of any such adjustment, and shall be protected in relying upon, an Officers’ Certificate and Opinion of Counsel, including the Officers’ Certificate with respect thereto which the Company is obligated to
file with the Trustee pursuant to Section 4.08. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities, and the Trustee shall not be responsible for the Company’s
failure to comply with any provisions of this Article IV. 
 (b) The Trustee shall not be under any responsibility to
determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 4.10, but may accept as conclusive evidence of the correctness thereof, and shall be fully protected in relying upon, the
Officers’ Certificate and Opinion of Counsel, with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 11.04. 
 Section 4.12 Voluntary Increase. 
 The Company from time to time may
increase the Conversion Rate, to the extent permitted by law, by any amount for any period of time if the period is at least 20 Business Days, and the Company provides 15 days’ prior written notice to any increase in the Conversion Rate to the
Trustee and Holders. The Company may also make such an increase to the Conversion Rate as the Board of Directors determines would avoid or diminish income tax to holders of shares of Common Stock in connection with a dividend or distribution of
stock (or rights to acquire stock) or from any event treated as such for income tax purposes. 
 Notwithstanding the foregoing
paragraph, in no event will the total number of shares of Common Stock issuable upon conversion of a Security exceed 116.2790 per $1,000 principal amount, subject to proportional adjustment in the same manner as the Conversion Rate as set forth
in clauses (1) and (2) of Section 4.06(a) hereof.

 ARTICLE V 
 COVENANTS 
 Section 5.01 Payment Of Securities. 

(a) The Company shall promptly make all payments in respect of the Securities on the dates and in the manner provided in the Securities
and this Indenture. A payment of principal or interest shall be considered paid on the date it is due if the Paying Agent (other than the Company) holds by 12:00 p.m. (noon), New York City time, on that date money, deposited by or on behalf of
the Company sufficient to make the payment. Subject to Section 4.02, accrued and unpaid 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. Principal, Redemption Price, Put Right Purchase Price, Fundamental Change
Repurchase Price, and interest, in each case if payable, shall be considered paid on the applicable date due if on such date (or, in the case of Put Right Purchase Price or Fundamental Change Repurchase Price, on the Business Day following the
applicable Put Right Purchase Date or Fundamental Change Repurchase Date, as the case may be) the Trustee or the Paying Agent holds, in accordance with this Indenture, money sufficient to pay all such amounts then due. 

(b) Payment of the principal of and interest, if any, on the Securities shall be made at the office or agency of the Company maintained
for that purpose at the Corporate Trust Office of the Trustee 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; provided, however, that at the
option of the Company payment of interest may be made through the Paying Agent by check mailed to the address of the Person entitled thereto as such address appears in the Register; provided further that a Holder with an aggregate principal amount
in excess of $2,000,000 will be paid by wire transfer in immediately available funds at the election of such Holder if such Holder has provided wire transfer instructions to the Trustee at least 10 Business Days prior to the payment date. Any wire
transfer instructions received by the Trustee will remain in effect until revoked by the Holder. 
 Section 5.02 SEC and
Other Reports. 
 (a) The Company shall file all reports and other information and documents which it is required to file
with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, and within 15 days after it files them with the SEC, the Company shall file copies of all such reports, information and other documents with the Trustee; provided that any such
reports, information and documents filed with the SEC pursuant to its Electronic Data Gathering, Analysis and Retrieval (or EDGAR) system shall be deemed to be filed with the Trustee. The Company also shall comply with the provisions of TIA
Section 314(a). 
 (b) 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 

  
 -46-









 
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). 
 Section 5.03 Compliance Certificates.

 The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company (beginning with
the fiscal year ending September 25, 2011), an Officers’ Certificate as to the signer’s knowledge of the Company’s compliance with all conditions and covenants on its part contained in this Indenture and stating whether or not
the signer knows of any Default or Event of Default. If such signer knows of such a Default or Event of Default, the Officers’ Certificate shall describe the Default or Event of Default and the efforts to remedy the same. For the purposes of
this Section 5.03, compliance shall be determined without regard to any grace period or requirement of notice provided pursuant to the terms of this Indenture. 
 Section 5.04 Further Instruments And Acts. 
 Upon request of the
Trustee, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture. 

Section 5.05 Maintenance Of Corporate Existence. 
 Subject to Article VI, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence. 

Section 5.06 Stay, Extension And Usury Laws. 
 The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay,
extension or usury law or other law which would prohibit or forgive the Company from paying all or any portion of the principal of or accrued but unpaid interest, if any, on the Securities as contemplated herein, wherever enacted, now or at any time
hereafter in force, or which may affect the covenants or the performance of this Indenture, and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not, by
resort to any such law, 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. 

Section 5.07 Maintenance of Office or Agency. 
 The Company will maintain an office or agency of the Trustee, Registrar and Paying Agent where securities may be presented or surrendered for payment, where Securities may be surrendered for registration
of transfer, purchase or redemption and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Corporate Trust Office shall initially be one such office or agency for all of the aforesaid
purposes. The Company shall give prompt written notice to the Trustee of the location, and of 

  
 -47-









 
any change in the location, of any such office or agency (other than a change in the location of the office of the Trustee). If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 11.02. 

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

 Section 6.01
Company May Consolidate, Etc., Only On Certain Terms. 
 The Company may not consolidate with or merge into any
Person or convey, transfer or lease the property and assets, substantially as an entirety, of the Company to another Person, other than to one or more of the Company’s wholly-owned subsidiaries, unless: 

(1) the Person (if other than the Company) formed by such consolidation or into which the Company is merged, or the Person
which acquires by conveyance, transfer or lease all or substantially all of the properties and assets of the Company, shall (i) be a corporation organized and existing under the laws of the United States of America or any State thereof or the

performance or observance of every covenant and provision of this Indenture and the Securities required on the part of the Company to be performed or observed and the conversion rights shall be provided for in accordance with Article IV, by
supplemental indenture executed and delivered to the Trustee, by the Person (if other than the Company) formed by such consolidation or into which the Company shall have been merged or by the Person which shall have acquired the Company’s
assets; 
 (2) after giving effect to such transaction, no Event of Default, and no event which, after notice or
lapse of time or both, would become an Event of Default, shall have occurred and be continuing; and 
 (3) if the
Company will not be the resulting or surviving corporation, the Company shall have, at or prior to the effective date of such consolidation, merger or transfer, delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each
stating that such consolidation, merger or transfer complies with this Article VI and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture complies with this Article VI, and that all

Upon any consolidation of the Company with, or merger of the Company into, any other Person or any conveyance, transfer or lease
substantially as an entirety, of the properties and assets of the Company and its Subsidiaries, taken as a whole, in accordance with Section 6.01, the successor Person formed by such consolidation or into which the Company is merged or to which
such conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein,
and thereafter, except in the case of a lease, and except for obligations the predecessor Person may have under a supplemental indenture, the predecessor Person shall be relieved of all obligations and covenants under this Indenture and the
Securities. 
 ARTICLE VII 
 DEFAULT AND REMEDIES 
 Section 7.01 Events Of Default. 

(a) An “Event of Default” shall occur if: 

(1) the Company shall fail to pay when due the Principal or any Redemption Price, Put Right Purchase Price or Fundamental
Change Repurchase Price of any Security, when the same becomes due and payable whether at the Final Maturity Date, upon redemption, repurchase, acceleration or otherwise; or 

(2) the Company shall fail to pay an installment of cash interest on any of the Securities, which failure continues for 30
days after the date when due; or 
 (3) the Company shall fail to deliver when due any consideration payable upon
conversion of the Securities, which failure continues for 15 days; or 
 (4) the Company shall fail to perform or
observe (or obtain a waiver with respect to) any other term, covenant or agreement contained in the Securities or this Indenture for a period of 60 days after receipt by the Company of a Notice of Default specifying such failure; or 

(5) default in the payment of principal by the end of any applicable grace period or resulting in acceleration of other
indebtedness of the Company for borrowed money where the aggregate principal amount with respect to which the default or acceleration has occurred exceeds $25 million and such acceleration has not been rescinded or annulled or such indebtedness
repaid within a period of 30 days after receipt of a Notice of Default, provided that if any such default is cured, waived, rescinded or annulled, then the Event of Default by reason thereof would be deemed not to have occurred; or 

  
 -49-









 (6) the Company pursuant to or within the meaning of any Bankruptcy Law:

 (A) commences as a debtor a voluntary case or proceeding; or 

(B) consents to the entry of an order for relief against it in an involuntary case or proceeding or the commencement of
any case against it; 
 (C) consents to the appointment of a Receiver of it or for all or substantially all of
its property; or 
 (D) makes a general assignment for the benefit of its creditors; 

(E) files a petition in bankruptcy or answer or consent seeking reorganization or relief; or 

(F) consents to the filing of such a petition or the appointment of or taking possession by a Receiver; or 

(7) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

(A) grants relief against the Company in an involuntary case or proceeding or adjudicates the Company insolvent or
bankrupt; 
 (B) appoints a Receiver of the Company or for all or substantially all of the property of the
Company; or 
 (C) orders the winding up or liquidation of the Company; 

and in each case the order or decree remains unstayed and in effect for 60 consecutive days. 

The term “Bankruptcy Law” means Title 11 of the United States Code (or any successor thereto) or any similar federal or
state law for the relief of debtors. The term “Receiver” means any receiver, trustee, assignee, liquidator, sequestrator or similar official under any Bankruptcy Law. 

(b) Notwithstanding Section 7.01(a), no Event of Default under clauses (4) or (5) of Section 7.01(a) shall occur
until the Trustee notifies the Company in writing, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding notify the Company and the Trustee in writing, of the Default (a “Notice of Default”), and
the Company does not cure the Default within the time specified in clause (4) or (5) of Section 7.01(a), as applicable, after receipt of such notice. A notice given pursuant to this


  
 -50-









 
Section 7.01 shall be given by registered or certified mail, must specify the Default, demand that it be remedied and state that the notice is a Notice of Default. When any Default under
this Section 7.01 is cured, it ceases. 
 (c) The Company will deliver to the Trustee, within five Business Days after
becoming aware of the occurrence of a Default or Event of Default, written notice thereof. 
 The Trustee shall not be charged
with knowledge of any Event of Default unless written notice thereof shall have been given to a Trust Officer with responsibility for this Indenture at the Corporate Trust Office of the Trustee by the Company, a Paying Agent, any Holder or any agent
of any Holder or unless a Trust Officer with responsibility for this Indenture acquires actual knowledge of such Event of Default in the course of performing other duties pursuant to this Indenture. 

Section 7.02 Acceleration. 
 If an Event of Default (other than an Event of Default specified in clauses (6) or (7) of Section 7.01(a)) occurs and is continuing with respect to the Company, the Trustee may, by notice
to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding may, by notice to the Company and the Trustee, declare the principal amount and accrued and unpaid interest, if any, through the date of
declaration on all the Securities to be immediately due and payable. Upon such a declaration, such principal amount and such accrued and unpaid interest, if any, shall be due and payable immediately. If an Event of Default specified in
Section 7.01(a)(6) or (7) occurs in respect of the Company and is continuing, the principal amount and accrued but unpaid interest, if any, on all the Securities shall become and be immediately due and payable without any declaration or
other act on the part of the Trustee or any Holders of Securities. The Holders of a majority in aggregate principal amount of the Securities then outstanding by notice to the Trustee may rescind an acceleration and its consequences if (a) all
existing Events of Default, other than the nonpayment of the principal of the Securities which have become due solely by such declaration of acceleration, have been cured or waived; (b) the rescission would not conflict with any judgment or
decree of a court of competent jurisdiction; and (c) all payments due to the Trustee and any predecessor Trustee under Section 8.07 have been made. No such rescission shall affect any subsequent Default or impair any right consequent
thereto. 
 Section 7.03 Other Remedies.
 (a) If an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated to, pursue any available remedy by proceeding at law or in equity to collect payment of the principal
amount and accrued and unpaid interest, if any, on the Securities or to enforce the performance of any provision of the Securities or this Indenture. 
 (b) The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in 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 to the extent permitted by applicable law.

Subject to Sections 7.07 and 10.02, the Holders of a majority in aggregate principal amount of the Securities then outstanding by

inconsistent with such direction.

indemnity; and

entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to, or, on behalf of any

(i) waive compliance by the Company with the restrictive provisions of this Indenture, and (ii) waive any past Default or Event of Default under this Indenture and its consequences, except an uncured failure to pay when due the principal
amount, accrued and unpaid interest, Redemption Price, Put Right Purchase Price or Fundamental Change Repurchase Price, or in the obligation to deliver any consideration due upon conversion, or in respect of any provision which under this Indenture
cannot be modified or amended without the consent of the Holder of each outstanding Security affected. 
 (c) It is not
necessary for the consent of the Holders of Securities under this Section 10.02 to approve the particular form of any proposed amendment, supplement or waiver, but is sufficient if such consent approves the substance thereof. 

(d) After an amendment, supplement or waiver under this Section 10.02 becomes effective, the Company shall promptly mail to the
Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment,
supplement or waiver.

indenture, the Trustee shall be entitled to receive and, subject to Section 8.01, shall be fully protected in relying upon, an Officers’ Certificate and Opinion of Counsel stating that such amendment or supplemental indenture is authorized

 Upon the execution
of any supplemental indenture under this Article X, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or

 [FORM OF REVERSE SIDE OF SECURITY] 

HUTCHINSON TECHNOLOGY INCORPORATED. 
 CONVERTIBLE SENIOR NOTES DUE 2026 
 1. INTEREST 

Hutchinson Technology Incorporated, a Minnesota corporation (the “Company”, which term shall include any successor corporation
under the Indenture hereinafter referred to), promises to pay interest on the principal amount of this Security at the rate of 8.50% per annum. The Company shall pay interest semiannually on January 15 and July 15 of each year (each
an “Interest Payment Date”), commencing July 15, 2011. Each payment of interest will include interest accrued through the day before the relevant Interest Payment Date (or purchase or redemption date, as the case may be). Cash
interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. 
 No sinking fund is provided for
the Securities. 
 2. METHOD OF PAYMENT 
 The Company shall pay interest on this Security (except defaulted interest) to the person who is the Holder of this Security at the close of business on January 1 or July 1, as the case may be
(each, a “Regular Record Date”), next preceding the related Interest Payment Date. The Holder must surrender this Security to a Paying Agent to collect payment of principal. The Company will pay principal and interest in money of the
United States that at the time of payment is legal tender for payment of public and private debts. The Company may pay principal and interest in respect of any Certificated Security through the Paying Agent by check or wire payable in such money;
provided, however, that a Holder with an aggregate principal amount in excess of $2,000,000 will be paid by wire transfer in immediately available funds at the election of such Holder if such Holder has provided wire transfer
instructions to the Trustee at least 10 Business Days prior to the Interest Payment Date. The Company may mail an interest check to the Holder’s registered address. Notwithstanding the foregoing, so long as this Security is registered in the
name of a Depositary or its nominee, all payments hereon shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. 
 Any wire transfer instructions received by the Trustee will remain in effect until revoked by the Holder. 
 3. PAYING AGENT, REGISTRAR AND CONVERSION AGENT 
 Initially, Wells Fargo Bank,
National Association (the “Trustee”, which term shall include any successor trustee under the Indenture hereinafter referred to) will act as Paying Agent, Registrar and Conversion Agent. The Company may change any Paying Agent, Registrar
or Conversion Agent without notice to the Holder. The Company or any of its Subsidiaries may, subject to certain limitations set forth in the Indenture, act as Paying Agent or Registrar.

 4. INDENTURE, LIMITATIONS 
 This Security is one of a duly authorized issue of Securities of the Company designated as its 8.50% Convertible Senior Notes Due 2026 (the “Securities”), issued under an Indenture dated as of
February [    ], 2011 (together with any supplemental indentures thereto, the “Indenture”), between the Company and the Trustee. The terms of this Security include those stated in the Indenture and those
required by or made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, as in effect on the date of the Indenture. This Security is subject to all such terms, and the Holder of this Security is referred to the
Indenture and said Act for a statement of them. 
 The Securities are senior unsecured obligations of the Company. The Indenture
does not limit debt of the Company, secured or unsecured. 
 5. REDEMPTION AT THE OPTION OF THE COMPANY 

Prior to January 15, 2013, the Securities shall not be redeemable. The Company may, at its option, redeem the Securities for cash at
the Redemption Price, in whole or in part, on any Redemption Date (or in the case of multiple redemptions, Redemption Dates) fixed by the Company (i) from time to time on or after January 15, 2013 to, but excluding, January 15, 2015,
if the Closing Price of the Common Stock equals or exceeds 150% of the Conversion Price in effect for at least 20 Trading Days during the 30 consecutive Trading Day period ending on the Trading Day immediately prior to the date the Company delivers
the redemption notice specified in Section 3.03 of the Indenture, and (ii) on and after January 15, 2015, at any time and from time to time. The Redemption Price shall equal 100% of the principal amount of the Securities to be
redeemed, plus any accrued and unpaid interest to, but excluding, the Redemption Date; provided, however, that if the Redemption Date falls after a Regular Record Date but on or prior to the corresponding Interest Payment Date, the
interest on the Securities payable on such Redemption Date will be payable to the Holders in whose names the Securities are registered at the close of business on the applicable Regular Record Date. Securities or portions of Securities called for
redemption shall be convertible by the Holder until the close of business on the second Business Day prior to the relevant Redemption Date. 

6. NOTICE OF REDEMPTION 

Notice of redemption, as set forth in Section 3.03 of the Indenture, will be mailed by first-class mail at least 30 days but not
more than 60 days before a Redemption Date to each Holder of Securities to be redeemed at its registered address. Securities in denominations larger than $1,000 may be redeemed in part, but only in whole multiples of $1,000. On and after the
Redemption Date, subject to the deposit with the Paying Agent of funds sufficient to pay the Redemption Price, such Securities or portions of them called for redemption will cease to be outstanding, whether or not the Security is delivered to the
Paying Agent, and the rights of the Holder in respect thereof shall cease (other than the right to receive the Redemption Price).

 7. PURCHASE OF SECURITIES AT OPTION OF HOLDER UPON A FUNDAMENTAL CHANGE 

At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase for
cash, subject to certain exceptions described in the Indenture, all or any part specified by the Holder (so long as the principal amount of such part is $1,000 or an integral multiple of $1,000) of the Securities held by such Holder on a date
specified by the Company that is not less than 30 nor more than 45 days after the date of the Fundamental Change Company Notice, at a purchase price equal to 100% of the principal amount thereof together with accrued and unpaid interest, if any, to,
but excluding, the Fundamental Change Repurchase Date. The Holder shall have the right to withdraw any Fundamental Change Repurchase Notice (in whole or in a portion thereof that is $1,000 or an integral multiple of $1,000) at any time prior to the
close of business on the Business Day next preceding the Fundamental Change Repurchase Date by delivering a written notice of withdrawal to the Paying Agent in accordance with the terms of the Indenture. 

8. PURCHASE OF SECURITIES AT OPTION OF HOLDER ON SPECIFIED DATES 
 At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase for cash all or any part specified by the Holder (so long as the
principal amount of such part is $1,000 or an integral multiple of $1,000) of the Securities held by such Holder on the applicable Put Right Purchase Date at the applicable Put Right Purchase Price. The Holder shall have the right to withdraw any
Put Right Purchase Notice (in whole or in a portion thereof that is $1,000 or an integral multiple of $1,000) at any time prior to the close of business on the Business Day next preceding the Put Right Purchase Date by delivering a written notice of
withdrawal to the Paying Agent in accordance with the terms of the Indenture. 
 9. CONVERSION 

Subject to and upon compliance with the provisions of the Indenture, a Holder may surrender for conversion any Security that is $1,000
principal amount or integral multiples thereof. Upon conversion of a Security, the Holder of such Security shall receive a number of shares of Common Stock equal to the product of (i) the number obtained by dividing the principal amount of the
Security converted by $1,000 and (ii) the Conversion Rate in effect on the applicable Conversion Date; provided, however, that in lieu of any fractional share of Common Stock, the Company shall deliver an amount of cash equal to the product of
(i) such fraction of a share and (ii) the Closing Price of the Common Stock on the applicable Conversion Date (or, if the applicable Conversion Date is not a Trading Day, the Trading Day immediately preceding such Conversion Date).

 10. DENOMINATIONS, TRANSFER, EXCHANGE 
 The Securities are in registered form, without coupons, in denominations of $1,000 principal amount and integral multiples of $1,000 principal amount. A Holder may register the transfer of or exchange
Securities in accordance with the Indenture. The Registrar may require a 

  
 A-6









 
Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes or other governmental charges that may be imposed in relation thereto by law or
permitted by the Indenture. 
 11. PERSONS DEEMED OWNERS 
 The Holder of a Security may be treated as the owner of it for all purposes. 
 12. UNCLAIMED MONEY

 If money for the payment of principal or interest remains unclaimed for two years, the Trustee and any Paying Agent will pay
the money back to the Company at its written request, subject to applicable unclaimed property law and the provisions of the Indenture. After that, Holders entitled to money must look to the Company for payment as general creditors unless an
applicable abandoned property law designates another person. 
 13. AMENDMENT, SUPPLEMENT AND WAIVER 

Subject to certain exceptions, the Indenture or the Securities may be amended or supplemented with the consent of the Holders of at least
a majority in aggregate principal amount of the Securities then outstanding, and an existing Default or Event of Default and its consequence or compliance with any provision of the Indenture or the Securities may be waived in a particular instance
with the consent of the Holders of a majority in aggregate principal amount of the Securities then outstanding. Without the consent of or notice to any Holder, the Company and the Trustee may amend or supplement the Indenture or the Securities to,
among other things, cure any ambiguity, defect or inconsistency or make any other change that does not adversely affect the rights of the Holders in any material respect. 
 14. SUCCESSOR ENTITY 
 When a successor corporation assumes all the obligations of
its predecessor under the Securities and the Indenture in accordance with the terms and conditions of the Indenture, the predecessor corporation (except in certain circumstances specified in the Indenture) shall be released from those obligations.

 15. DEFAULTS AND REMEDIES 
 Under the Indenture, an Event of Default shall occur if: 
 (1) the Company shall
fail to pay when due the Principal or any Redemption Price, Put Right Purchase Price or Fundamental Change Repurchase Price of any Security, when the same becomes due and payable whether at the Final Maturity Date, upon redemption, repurchase,
acceleration or otherwise; or 
 (2) the Company shall fail to pay an installment of cash interest on any of the Securities,
which failure continues for 30 days after the date when due; or 

  
 A-7









 (3) the Company shall fail to deliver when due any consideration payable upon conversion of
the Securities, which failure continues for 15 days; or 
 (4) the Company shall fail to perform or observe (or obtain a waiver
with respect to) any other term, covenant or agreement contained in the Securities or the Indenture for a period of 60 days after receipt by the Company of a Notice of Default specifying such failure; or 

(5) default in the payment of principal by the end of any applicable grace period or resulting in acceleration of other indebtedness of
the Company for borrowed money where the aggregate principal amount with respect to which the default or acceleration has occurred exceeds $25 million and such acceleration has not been rescinded or annulled or such indebtedness repaid within a
period of 30 days after receipt of a Notice of Default, provided that if any such default is cured, waived, rescinded or annulled, then the Event of Default by reason thereof would be deemed not to have occurred; or 

(6) the Company pursuant to or within the meaning of any Bankruptcy Law: 

(A) commences as a debtor a voluntary case or proceeding; or 
 (B) consents to the entry of an order for relief against it in an involuntary case or proceeding or the commencement of any case against it; or 

(C) consents to the appointment of a Receiver of it or for all or substantially all of its property; or 

(D) makes a general assignment for the benefit of its creditors; or 

(E) files a petition in bankruptcy or answer or consent seeking reorganization or relief; or 

(F) consents to the filing of such a petition or the appointment of or taking possession by a Receiver; or 

(7) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

(A) grants relief against the Company in an involuntary case or proceeding or adjudicates the Company insolvent or bankrupt; 

(B) appoints a Receiver of the Company or for all or substantially all of the property of the Company; or 

(C) orders the winding up or liquidation of the Company; 
 and in each case the order or decree remains unstayed and in effect for 60 consecutive days. 

  
 A-8









 The term “Bankruptcy Law” means Title 11 of the United States Code (or any
successor thereto) or any similar federal or state law for the relief of debtors. The term “Receiver” means any receiver, trustee, assignee, liquidator, sequestrator or similar official under any Bankruptcy Law. 

Notwithstanding the above, no Event of Default under clauses (4) or (5) above shall occur until the Trustee notifies the
Company in writing, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding notify the Company and the Trustee in writing, of the Default (a “Notice of Default”), and the Company does not cure the
Default within the time specified in clause (4) or (5), as applicable, after receipt of such notice. 
 If an Event of
Default (other than an Event of Default specified in clauses (6) or (7) above) occurs and is continuing with respect to the Company, the Trustee may, by notice to the Company, or the Holders of at least 25% in aggregate principal amount of
the Securities then outstanding may, by notice to the Company and the Trustee, declare the principal amount and accrued and unpaid interest, if any, through the date of declaration on all the Securities to be immediately due and payable. Upon such a
declaration, such principal amount and such accrued and unpaid interest, if any, shall be due and payable immediately. If an Event of Default specified in clauses (6) or (7) occurs in respect of the Company and is continuing, the principal
amount and accrued but unpaid interest, if any, on all the Securities shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders of Securities. The Holders of a majority in
aggregate principal amount of the Securities then outstanding by notice to the Trustee may rescind an acceleration and its consequences if (a) all existing Events of Default, other than the nonpayment of the principal of the Securities which
have become due solely by such declaration of acceleration, have been cured or waived; (b) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (c) all payments due to the Trustee and any
predecessor Trustee under the Indenture have been made. No such rescission shall affect any subsequent Default or impair any right consequent thereto. Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The
Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default (except a Default in payment of principal or interest) if and so long as it determines that withholding notice is in their interests. The Company
is required to file periodic certificates with the Trustee as to the Company’s compliance with the Indenture and knowledge or status of any Default. 
 16. TRUSTEE DEALINGS WITH THE COMPANY 
 Wells Fargo Bank, National Association,
the initial Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from and perform services for the Company or an Affiliate of the Company, and may otherwise deal with the Company or an Affiliate of
the Company, as if it were not the Trustee. 

  
 A-9









 17. NO RECOURSE AGAINST OTHERS 
 A director, officer, employee or shareholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities or the Indenture nor for any claim based on, in
respect of or by reason of such obligations or their creation. The Holder of this Security by accepting this Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of this Security.

accordance with, the laws of the State of New York.
