of the new Notes issued upon such exchange or registration of transfer of Notes being different from the name of the holder of the old Notes presented or surrendered for such exchange or registration of transfer. 
 None of the Company, the Trustee, the Note Registrar or any co-registrar shall be required to exchange or register a transfer of
(i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion or (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not

therefor. 
 (c) Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under
this Indenture with respect to any Global Note held on their behalf by the Depositary or under the Global Note, and the Depositary (including, for this purpose, its nominee) 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 Note for all purposes whatsoever. 
 (d) Notwithstanding any other
provisions of this Indenture, a Global Note may not be transferred as a whole or in part except (i) 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 and (ii) for transfers of portions of a Global Note in certificated form made upon request of a member of, or a participant in, the
Depositary (for itself or on behalf of a beneficial owner) by written notice given to the Trustee by or on behalf of the Depositary in accordance with customary procedures of the Depositary and in compliance with this Section. 
 The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to
act as Depositary with respect to the Global Note. Initially, the Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for
Cede & Co. 
 If (i) the Depositary notifies the Company at any time that the Depositary is unwilling or unable to
continue as depositary for the Global Notes and a successor depositary is not appointed within 90 days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed
within 90 days or (iii) an Event of Default in respect of the Notes has occurred and is continuing, upon the request of the beneficial owner of the Notes, the Company will execute, and the Trustee, upon receipt of an Officers’
Certificate and a Company Order for the authentication and delivery of Physical Notes, will authenticate and deliver Physical Notes in definitive form to each such beneficial owner of the related Notes (or a portion thereof) in an aggregate
principal amount equal to the principal amount of such Global Note, in exchange for such Global Note, and upon delivery of the Global Note to the Trustee such Global Note shall be canceled. 
 Physical Notes issued in exchange for all or a part of the Global Note pursuant to this Section 2.06(d) shall be registered in
such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical
Notes to the Persons in whose names such Physical Notes are so registered. 
  

 18 








 At such time as all interests in a Global Note have been converted, canceled, repurchased or
transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the Custodian. At any time prior to such cancellation, if any interest
in a Global Note is exchanged for Physical Notes, converted, canceled, repurchased or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal
amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such
Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase. 
 None of
the Company, the Trustee nor any agent of the Company or the Trustee will have any responsibility or liability for any actions taken or not taken by the Depositary or any aspect of the records relating to or payments made on account of beneficial
ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 
 SECTION 2.07 Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its written
request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in
substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by
them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if
applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 
 The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon the receipt of such security or indemnity as the Trustee, the Company and, if applicable, such
authenticating agent may require. Upon the issuance of any substitute Note, the Company or the Trustee may require the payment by the holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in
relation thereto and any other expenses connected therewith. In case any Note that has matured or is about to mature or has been tendered for repurchase upon a Fundamental Change or is about to be converted into cash, shares of Common Stock or a
combination of cash and shares of Common Stock, as applicable, shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or
authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such
authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, including without limitation if a Note is replaced and
subsequently presented or claimed for payment and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent evidence of their satisfaction of the
destruction, loss or theft of such Note and of the ownership thereof. 
  

 19 








 Every substitute Note issued pursuant to the provisions of this Section 2.07 by
virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the
benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express
condition that the foregoing provisions are exclusive with respect to the replacement or payment or conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any
law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion of negotiable instruments or other securities without their surrender. 
 SECTION 2.08 Temporary Notes. Pending the preparation of Notes in certificated form, the Company may execute and the Trustee or an
authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the
form of the Notes in certificated form but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and
authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Notes in certificated form. Without unreasonable delay the Company will execute and deliver to
the Trustee or such authenticating agent Notes in certificated form (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained
by the Company pursuant to Section 9.02 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Notes in certificated form. Such exchange
shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Notes in
certificated form authenticated and delivered hereunder. 
 SECTION 2.09 Cancellation of Notes Paid, Etc. All Notes
surrendered for the purpose of payment, repurchase, conversion, exchange or registration of transfer, shall, if surrendered to the Company or any Paying Agent or any Note Registrar or any Conversion Agent, be surrendered to the Trustee and promptly
canceled by it, or, if surrendered to the Trustee, shall be promptly canceled by it, and no Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of canceled Notes
in accordance with its customary procedures. If the Company shall acquire any of the Notes, such acquisition shall not operate as satisfaction of the Indebtedness represented by such Notes unless and until the same are delivered to the Trustee for
cancellation. 
 SECTION 2.10 CUSIP Numbers. In issuing the Notes, the Company may use “CUSIP” numbers
(if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices issued to Holders of the Notes as a convenience to them; provided that any such notice

  

 20 








 
may state that no representation is made as to the correctness of such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification
numbers printed on the Notes. The Company will promptly notify the Trustee in writing of any change in the “CUSIP” numbers. 
 SECTION 2.11 Repurchases. The Company may from time to time repurchase the Notes in open market purchases or otherwise without prior notice to Holders of Notes. Any Notes repurchased by the Company will be immediately retired and not
be outstanding for any purpose under the Indenture. 
 ARTICLE 3 
 FUNDAMENTAL CHANGES AND PURCHASES THEREUPON 
 SECTION
3.01 Purchase at Option of Holders Upon a Fundamental Change. 
 (a) Generally. If a Fundamental Change occurs at
any time prior to October 15, 2014, then each Holder of Notes shall have the right, at such Holder’s option, to require the Company to purchase for cash any or all of such Holder’s Notes, or any portion of the principal amount
thereof, that is equal to $1,000 or a multiple of $1,000, on a date specified by the Company that is no earlier than the 20th calendar day following the date of, and no later than the 35th calendar day following the date of, delivery of the
Fundamental Change Company Notice (as defined below) (the “Fundamental Change Purchase Date”), at a purchase price equal to 100% of the principal amount thereof, together with accrued and unpaid interest thereon to, but excluding,
the Fundamental Change Purchase Date (the “Fundamental Change Purchase Price”); provided, however, that if a Fundamental Change Purchase Date is after a Regular Record Date and on or prior to the Interest Payment Date
to which such Regular Record Date relates, the interest payable in respect of such Interest Payment Date shall be payable to the Holders of record as of the corresponding Regular Record Date and the Fundamental Change Purchase Price shall be equal
to 100% of the principal amount of the Notes to be purchased pursuant to this Article 3. Any Notes purchased by the Company will be paid for in cash. The requirement for the Company to purchase any Notes on the Fundamental Change
Purchase Date will be subject to extension to comply with applicable law. 
 Purchases of Notes under this
Section 3.01 shall be made, at the option of the Holder thereof, upon: 
 (i) delivery to the Paying
Agent by a Holder of a duly completed notice (the “Fundamental Change Purchase Notice”) in the form set forth on the reverse of the Note as Exhibit C thereto, if the Notes are Physical Notes, or in compliance with the
Depositary’s procedures for tendering interests in Global Notes, if the Notes are not Physical Notes, in each case prior to the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date; and 
 (ii) delivery of the Notes, in the case of Physical Notes, to the Paying Agent appointed by the Company (together with all
necessary endorsements for transfer), or book-entry transfer of the Notes, in compliance with the procedures of the Depositary, such delivery or transfer being a condition to receipt by the Holder of the Fundamental Change Purchase Price therefor.

  

 21 








 The Fundamental Change Purchase Notice in respect of any Notes to be purchased shall state:

 (i) if such Notes are Physical Notes, the certificate numbers of such Notes, or if such Notes are in global
form, the Fundamental Change Purchase Notice must also comply with appropriate procedures of the Depositary; 
 (ii) the portion of the principal amount of such Notes, which must be $1,000 or a multiple thereof; and 
 (iii) that such Notes are to be purchased by the Company pursuant to the applicable provisions of the Notes and this Indenture. 
 Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Purchase Notice contemplated by this Section 3.01 shall have the right to
withdraw, in whole or in part, such Fundamental Change Purchase Notice at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date by delivery of a written notice of withdrawal to the
Paying Agent in accordance with Section 3.03 below. 
 The Paying Agent shall promptly notify the Company of the
receipt by it of any Fundamental Change Purchase Notice or written notice of withdrawal thereof. 
 (b) Fundamental Change
Company Notice. On or before the 20th calendar day after the occurrence of a Fundamental Change, the Company shall provide to all Holders of the Notes, the Trustee and the Paying Agent (in the case of any Paying Agent other than the Trustee) a
notice (the “Fundamental Change Company Notice”) of the occurrence of such Fundamental Change and of the purchase right at the option of the Holders arising as a result thereof. Such notice shall be sent by first class mail or, in
the case of any Global Notes, in accordance with the procedures of the Depositary for providing notices. Simultaneously with providing such Fundamental Change Company Notice, the Company shall issue a press release or publish a notice containing the
information included therein or shall publish such information on the Company’s website or through such other public medium as the Company may use at such time. 
 Each Fundamental Change Company Notice shall specify: 
 (i) the
events causing a Fundamental Change; 
 (ii) the date of the Fundamental Change; 
 (iii) the last date on which a Holder of Notes may exercise the repurchase right pursuant to this Article 3;

 (iv) the Fundamental Change Purchase Price; 
 (v) the Fundamental Change Purchase Date; 
  

 22 








 (vi) the name and address of the Paying Agent and the Conversion Agent, if
applicable; 
 (vii) if applicable, the applicable Conversion Rate and any adjustments to the applicable
Conversion Rate; 
 (viii) if applicable, that the Notes with respect to which a Fundamental Change Purchase
Notice has been delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Purchase Notice in accordance with the Indenture; and 
 (ix) the procedures that Holders must follow to require the Company to purchase their Notes. 
 No failure of the Company to give the foregoing notices and no defect therein shall limit the purchase rights of the Holders of Notes or
affect the validity of the proceedings for the purchase of the Notes pursuant to this Section 3.01. 
 (c) No
Payment During Events of Default. There shall be no purchase of any Notes pursuant to this Section 3.01 if there has occurred and is continuing an Event of Default with respect to the Notes (other than an Event of Default that is
cured by the payment of the Fundamental Change Purchase Price of the Notes). The Paying Agent will promptly return to the respective Holders thereof any Physical Notes held by it during the continuance of an Event of Default (other than an Event of
Default that is cured by the payment of the Fundamental Change Purchase Price with respect to the Notes) and shall deem canceled any instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary, in which
case, upon such return and cancellation, the Fundamental Change Purchase Notice with respect thereto shall be deemed to have been withdrawn. 
 SECTION 3.02 Effect of Fundamental Change Purchase Notice. Upon receipt by the Paying Agent of the Fundamental Change Purchase Notice specified in Section 3.01 hereof, the Holder
of the Note in respect of which such Fundamental Change Purchase Notice was given shall (unless such Fundamental Change Purchase Notice is withdrawn in accordance with Section 3.03 hereof) thereafter be entitled to receive solely the
Fundamental Change Purchase Price in cash with respect to such Note. Such Fundamental Change Purchase Price shall be paid to such Holder, subject to receipt of funds by the Paying Agent, on the later of (x) the Fundamental Change Purchase Date
with respect to such Note (provided the conditions in Section 3.01 hereof have been satisfied) and (y) the time of delivery or book-entry transfer of such Note to the Paying Agent by the Holder thereof in the manner required
by Section 3.01 hereof. 
 SECTION 3.03 Withdrawal of Fundamental Change Purchase Notice. A
Fundamental Change Purchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Paying Agent in accordance with the Fundamental Change Company Notice at any time prior to the close of business on
the Business Day immediately preceding the Fundamental Change Purchase Date, specifying: 
 (i) the principal
amount of the Notes with respect to which such notice of withdrawal is being submitted; 
  

 23 








 (ii) if Physical Notes have been issued, the certificate numbers of the
withdrawn Notes, or if Physical Notes have not been issued, the notice must comply with appropriate procedures of the Depositary; and 
 (iii) the principal amount, if any, of such Notes that remains subject to the original Fundamental Change Purchase Notice, which portion must be in principal amounts of $1,000 or a multiple of $1,000.

 The Paying Agent will promptly return to the respective Holders thereof any Physical Notes with respect to which a
Fundamental Change Purchase Notice has been withdrawn in compliance with the provisions of this Section 3.03. 
 SECTION 3.04 Deposit of Fundamental Change Purchase Price. Prior to 11:00 a.m. (local time in The City of New York) on the Fundamental Change Purchase Date, the Company shall deposit with the Paying Agent (or, if the
Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided herein) an amount of money (in immediately available funds if deposited on such Business Day) sufficient to pay
the Fundamental Change Purchase Price of all the Notes or portions thereof that are to be purchased as of the Fundamental Change Purchase Date. If the Paying Agent holds cash sufficient to pay the Fundamental Change Purchase Price of the Notes for
which a Fundamental Change Purchase Notice has been tendered and not withdrawn in accordance with this Indenture on the Fundamental Change Purchase Date, then as of such Fundamental Change Purchase Date, (a) such Notes will cease to be
outstanding and interest will cease to accrue thereon (whether or not book-entry transfer of such Notes is made or such Notes have been delivered to the Paying Agent) and (b) all other rights of the Holders in respect thereof will terminate
(other than the right to receive the Fundamental Change Purchase Price and previously accrued and unpaid interest upon delivery or book-entry transfer of such Notes). 
 SECTION 3.05 Notes Purchased in Whole or in Part. Any Note that is to be purchased, whether in whole or in part, shall be surrendered at the office of the Paying Agent (with, if the Company
or the Trustee so requires in the case of Physical Notes, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized
in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Note, without service charge, a new Note or Notes, of any authorized denomination as requested by such Holder in aggregate principal
amount equal to, and in exchange for, the portion of the principal amount of the Note so surrendered that is not purchased. 
 SECTION 3.06 Covenant to Comply With Applicable Laws Upon Purchase of Notes. In connection with any offer to purchase Notes under Section 3.01 hereof, the Company shall, in each case if required, (i) comply
with Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable, (ii) file a Schedule TO or any other required schedule under the Exchange Act and (iii) otherwise comply with all
federal and state securities laws so as to permit the rights and obligations under Section 3.01 to be exercised in the

  

 24 








 
time and in the manner specified in Section 3.01, and shall not be deemed to have breached its obligations under the Indenture by virtue of its compliance with such securities laws or
regulations. 
 SECTION 3.07 Repayment to the Company. To the extent that the aggregate amount of cash deposited by the
Company pursuant to Section 3.04 exceeds the aggregate Fundamental Change Purchase Price of the Notes or portions thereof that the Company is obligated to purchase as of the Fundamental Change Purchase Date, then, following the
Fundamental Change Purchase Date, the Paying Agent shall promptly return any such excess to the Company. 
 ARTICLE 4 

 CONVERSION 
 SECTION 4.01 Right to Convert. (a) Subject to and upon compliance with the provisions of this Indenture, each Holder of Notes shall have the right, at such Holder’s option, to convert the
principal amount of any such Notes, or any portion of such principal amount equal to $1,000 or a multiple of $1,000 thereof, at the Conversion Rate in effect on the Conversion Date for such Notes, (x) prior to April 15, 2014, only upon
satisfaction of one or more of the conditions described in clauses (i) through (iv) below and (y) on or after April 15, 2014, at any time prior to the close of business on the second Scheduled Trading Day immediately preceding
October 15, 2014 irrespective of the conditions described in clauses (i) through (iv) below: 
 (i) Prior to April 15, 2014, a Holder of Notes may surrender all or a portion of its Notes for conversion during any fiscal quarter (and only during such fiscal quarter) commencing after January 31, 2009 if the Last Reported Sale
Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding fiscal quarter is greater than or equal to 130% of
the applicable Conversion Price in effect on each applicable Trading Day. The Company shall notify the Trustee and the Conversion Agent if the Notes become convertible in accordance with this Section 4.01(a)(i). 
 (ii) Prior to April 15, 2014, a Holder of Notes may surrender its Notes for conversion during the five Business Day
period after any five consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder of Notes in accordance with the
procedures set forth in this Section 4.01(a)(ii), for each Trading Day of such period was less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on such Conversion Date (the
“Trading Price Condition”). The Bid Solicitation Agent shall have no obligation to determine the Trading Price of the Notes in accordance with this Section 4.01(a)(ii) unless requested by the Company, and the Company
shall have no obligation to make such request unless a Holder of Notes provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than 98% of the product of the Last Reported Sale Price of
the Common Stock and the applicable Conversion Rate. The Company shall instruct the Bid Solicitation Agent to determine (or, if the Company is then acting as Bid Solicitation Agent, the Company shall determine) the Trading Price of

  

 25 








 
the Notes beginning on the next Trading Day promptly following the receipt of such evidence and on each successive Trading Day until such Trading Day on which the Trading Price per $1,000
principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate. If the Company does not so instruct the Bid Solicitation Agent to obtain (or, if the
Company is then acting as Bid Solicitation Agent, the Company does not obtain) bids when required, the Trading Price per $1,000 principal amount of the Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the
Common Stock and the applicable Conversion Rate on each day the Company fails to do so. If the Trading Price Condition has been met, the Company shall so notify Holders, the Trustee and the Conversion Agent. If, at any time after the Trading Price
Condition has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate for such date, the Company shall so notify
Holders, the Trustee and the Conversion Agent. 
 (iii) If the Company elects to: 
 (A) issue to all or substantially all holders of Common Stock rights or warrants entitling them for a period of not more than
45 calendar days after the date of such issuance to subscribe for or purchase shares of Common Stock at less than the average of the Last Reported Sale Prices of a share of Common Stock for the 10 consecutive Trading Day period ending on the Trading
Day immediately preceding the date of announcement of such issuance; or 
 (B) distribute to all or substantially
all holders of Common Stock assets, debt securities or rights to purchase securities of the Company, which distribution has a per share value, as reasonably determined by the Board of Directors, exceeding 10% of the Last Reported Sale Price of the
Common Stock on the Trading Day preceding the date of announcement for such distribution, 
 then, in each case, the Company
shall notify the Holders of the Notes at least 45 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice, Holders may surrender Notes for conversion at any time until the
earlier of the close of business on the Business Day immediately prior to such Ex-Dividend Date or the Company’s announcement that such issuance or distribution will not take place, even if the Notes are not otherwise convertible at such time.

 (iv) If a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change
occurs, regardless of whether a Holder has the right to require the Company to purchase the Notes pursuant to Article 3 hereof, or if the Company is a party to a consolidation, merger, binding share exchange, or sale, transfer or lease of all
or substantially all of the Company’s assets, in each case, pursuant to which the Common Stock would be converted into cash, securities or other assets, Holders may surrender Notes for conversion at any time from or after the date which is

  

 26 








 
45 Scheduled Trading Days prior to the anticipated effective date of such transaction until 35 Trading Days after the actual effective date of such transaction (or, if such transaction also
constitutes a Fundamental Change, until the related Fundamental Change Purchase Date). The Company shall notify Holders and the Trustee as promptly as practicable following the date the Company publicly announces such transaction, but in no event
less than 45 Scheduled Trading Days prior to the anticipated effective date of such transaction. 
 Failure by the Company to
give any notice required by Section 4.01, or any defect therein, shall not affect the legality or validity of the relevant transaction or event. 
 (b) Notes may not be converted after the close of business on the second Scheduled Trading Day immediately preceding October 15, 2014. 
 SECTION 4.02 Conversion Procedures. (a) Each Note shall be convertible at the office of the Conversion Agent and, if applicable, in
accordance with the procedures of the Depositary. 
 (b) In order to exercise the conversion privilege with respect to any
interest in a Global Note, the Holder must comply with the Depositary’s procedures for converting an interest in a Global Note and, if required, pay the funds required by Section 4.03(e) and pay any taxes or duties if required
pursuant to Section 4.08, and the Conversion Agent must be informed of the conversion in accordance with the customary practice of the Depositary. In order to exercise the conversion privilege with respect to any Physical Notes, the
Holder of any such Notes to be converted, in whole or in part, shall: 
 (i) complete and manually sign the
conversion notice provided on the back of the Note (the “Conversion Notice”) or a facsimile of the Conversion Notice; 
 (ii) deliver the Conversion Notice, which is irrevocable, and the Note to the Conversion Agent; 
 (iii) if required, furnish appropriate endorsements and transfer documents, 
 (iv) make any payment required under Section 4.03(e); and 
 (v) if required, pay all transfer or similar taxes as set forth in Section 4.08. 
 The date on which the Holder satisfies
all of the applicable requirements set forth above is the “Conversion Date.” The Conversion Agent will, as promptly as possible, and in any event within two Business Days of the receipt thereof, provide the Company with notice of
any conversion by a Holder of the Notes. 
 (c) Each Conversion Notice shall state the name or names (with address or addresses)
in which any certificate or certificates for shares of Common Stock which shall be issuable on such conversion shall be issued. All such Notes surrendered for conversion shall, unless the shares issuable on conversion are to be issued in the same
name as the registration of such Notes, be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or his duly authorized attorney. 
  

 27 








 (d) In case any Notes of a denomination greater than $1,000 shall be surrendered for partial
conversion, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of the Notes so surrendered, without charge, new Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion
of the surrendered Notes. 
 (e) Each conversion shall be deemed to have been effected as to any Notes (or portion thereof)
surrendered for conversion on the relevant Conversion Date, and with respect to any shares of Common Stock that are issuable upon such conversion: (i) if such conversion was subject to a Physical Settlement, the Person in whose name the
certificate or certificates for such shares of Common Stock will be registered, shall become the holder of record of such shares as of the close of business on the Conversion Date; and (ii) if such conversion was subject to a Combination
Settlement, the Person in whose name the certificate or certificates for such shares of Common Stock will be registered, shall become the holder of record of such shares as of the close of business on the last Trading Day of the related Observation
Period. 
 (f) Upon the conversion of an interest in Global Notes, the Trustee (or other Conversion Agent appointed by the
Company) shall make a notation on such Global Notes as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversions of Notes effected through any Conversion Agent other than the
Trustee. 
 (g) Notwithstanding the foregoing, a Note in respect of which a Holder has delivered a Fundamental Change Purchase
Notice exercising such Holder’s option to require the Company to purchase such Note may be converted only if such notice of exercise is withdrawn in accordance with Article 3 hereof prior to the close of business on the Business Day
prior to the relevant Fundamental Change Purchase Date. 
 SECTION 4.03 Settlement Upon Conversion. (a) Except as
provided in Section 4.06(b), upon any conversion of any Note, the Company shall deliver to converting Holders, in respect of each $1,000 principal amount of Notes being converted, at the Company’s election, in full satisfaction of
the Company’s Conversion Obligation, (1) shares of Common Stock, together with cash in lieu of fractional shares, if any (a “Physical Settlement”), (2) a cash payment without any delivery of shares of Common Stock (a
“Cash Settlement”) or (3) a combination of cash and shares of Common Stock, together with cash in lieu of fractional shares, if any (a “Combination Settlement”), in each case, as set forth below (the amounts so
deliverable upon conversion of the Notes, the “Conversion Obligation”): 
 For conversions: 
 (i) that occur prior to April 15, 2014, by the close of business on the Business Day following the Conversion Date, the
Company shall notify converting Holders of the relevant Settlement Method and, if the Company elects a Combination Settlement, the dollar amount of the conversion obligation (the “Cash Amount”) that will be settled in cash;

  

 28 








 (ii) that occur on or after April 15, 2014, the Company shall notify
all Holders of the relevant Settlement Method and, if applicable, the related Cash Amount, by notice on or prior to April 15, 2014 (which shall apply to all conversions on or following April 15, 2014). 
 If the Company does not specify a Settlement Method as set forth above, then Combination Settlement shall apply, and the related Cash Amount
used in the settlement calculation set forth in paragraph (d) below will be $1,000. Any such notice of a Settlement Method may not be revoked. 
 (b) If the Company has elected a Physical Settlement with respect to any Notes tendered for conversion, the Company shall deliver, for each $1,000 principal amount of Notes, a number of shares of Common
Stock equal to the Conversion Rate, together with cash in lieu of fractional shares. Except for conversions upon a Make-Whole Fundamental Change as provided in Section 4.06, the Company shall deliver such shares of Common Stock
(1) on the third Business Day following the Conversion Date, in the case of a Physical Settlement with respect to a Conversion Date on or prior to the Business Day immediately preceding April 15, 2014, or (2) on the third Business Day
following the last day of the applicable Observation Period, in the case of a Physical Settlement with respect to a Conversion Date on or after April 15, 2014. 
 (c) If the Company has elected a Cash Settlement with respect to any Notes tendered for conversion, the Company shall deliver, for each $1,000 principal amount of Notes, a cash payment equal to the sum of
the Daily Conversion Values for each of the forty (40) consecutive Trading Days during the relevant Observation Period. Except for conversions upon a Make-Whole Fundamental Change as provided in Section 4.06, the Company shall make
such payment on the third Business Day following the last day of the applicable Observation Period. 
 (d) If the Company has
elected or is deemed to have elected a Combination Settlement with respect to any Notes tendered for conversion, the Company shall deliver, for each $1,000 principal amount of Notes, the sum of the Daily Settlement Amounts for each of the forty
(40) consecutive Trading Days during the relevant Observation Period. 
 The “Daily Settlement Amount” for
each of the forty (40) consecutive Trading Days during the Observation Period shall consist of: 
 (i) cash
in an amount equal to the lesser of (i) 2.5% of the cash amount specified by the Company in the notice regarding the chosen Settlement Method (the “Daily Cash Amount”) and (ii) the Daily Conversion Value on such Trading
Day; and 
 (ii) if the Daily Conversion Value on such Trading Day exceeds the Daily Cash Amount, a number of
shares of Common Stock (together with cash in lieu of any fractional shares) equal to (i) the difference between such Daily Conversion Value and the Daily Cash Amount, divided by (ii) the Daily VWAP on such Trading Day. 
 Except for conversions upon a Make-Whole Fundamental Change as provided in Section 4.06, the Company shall deliver such cash and
shares of Common Stock on the third Business Day following the last day of the applicable Observation Period. 
  

 29 








 (e) Upon conversion of any Notes, Holders shall not receive any separate cash payment for
accrued and unpaid interest, except to the extent specified below. The Company’s delivery to the Holder of Common Stock, cash or a combination of cash and Common Stock, as applicable, together with any cash payment for any fractional share of
Common Stock, into which a Note is convertible shall be deemed to satisfy in full the Company’s obligation to pay (i) the principal amount of the Notes so converted and (ii) accrued and unpaid interest to, but not including, the
Conversion Date. As a result, accrued and unpaid interest to, but not including, the Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Notes surrendered for conversion during the period from the
close of business on any Regular Record Date to the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted; provided that no such
payment need be made (i) for conversions following the Regular Record Date immediately preceding April 15, 2014, (ii) if the Company has specified a Fundamental Change Purchase Date that is after a Regular Record Date and on or prior
to the corresponding Interest Payment Date, or (iii) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Note. 
 (f) The Company shall not issue fractional shares of Common Stock upon conversion of Notes. If multiple Notes shall be surrendered for
conversion at one time by the same Holder, the number of full shares of Common Stock which shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent
permitted hereby) so surrendered. If any fractional share of Common Stock would be issuable upon the conversion of any Notes, the Company shall make payment therefor in cash in lieu of fractional shares of Common Stock based on: 
 (i) if Physical Settlement applies, on the Last Reported Sale Price of the Common Stock on the relevant Conversion Date, and

 (ii) if Combination Settlement applies, the Daily VWAP of the Common Stock on the final Trading Day of the
applicable Observation Period. 
 (g) Solely for purposes of determining the payments and deliveries due upon conversion under
this Section 4.03, and notwithstanding the definition of “Trading Day” contained in Section 1.02, “Trading Day” means a day on which (i) there is no Market Disruption Event and
(ii) trading in the Common Stock generally occurs on the New York Stock Exchange or, if the Common Stock is not then listed on the New York Stock Exchange, on the principal other United States national or regional securities exchange on which
the Common Stock is then listed or, if the Common Stock is not then listed on a United States national or regional securities exchange, on the principal other market on which the Common Stock is then traded. If the Common Stock (or other security
for which a Daily VWAP must be determined) is not so listed or traded, “Trading Day” means a Business Day. 
 (h) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change, the Company shall deliver shares of Common Stock, cash or a combination of cash and shares of Common Stock, as set forth above, at the increased
Conversion Rate as described in Section 4.06. 
  

 30 








 SECTION 4.04 Adjustment of Conversion Rate. The Conversion Rate shall be adjusted
from time to time by the Company if any of the following events occurs, except that the Company will not make any adjustment to the Conversion Rate if Holders of Notes participate, as a result of holding the Notes, in any of the transactions
described under Section 4.04(a) (but only with respect to stock dividends or distributions), Section 4.04(b), Section 4.04(c), and Section 4.04(d), at the same time as holders of the Common Stock
participate, without having to convert their Notes, as if such Holders held a number of shares of Common Stock equal to the Conversion Rate in effect for each $1,000 principal amount of such Notes immediately prior to the Ex-Dividend Date for such
event. 
 (a) If the Company, at any time or from time to time while any of the Notes are outstanding, exclusively issues shares
of its Common Stock as a dividend or distribution on shares of Common Stock, or if the Company effects a share split or share combination, then the Conversion Rate shall be adjusted based on the following formula: 
  

									
	 CR1
	  	=	  	CR0	 	x  	 	  
 OS1

	  	  	 	 	OS0

 where 
  

					
	 CR0
	  	=	  	The Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the open of business on
the effective date of such share split or share combination, as applicable;
			
	 CR1
	  	=	  	The Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or such effective date;
			
	 OS0
	  	=	  	The number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or such effective date; and
			
	 OS1
	  	=	  	The number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination.

 Such adjustment shall become effective immediately after the open of business on the Ex-Dividend Date
for such dividend or distribution or the effective date for such share split or share combination. If any dividend or distribution of the type described in this Section 4.04(a) is declared but not so paid or made, the Conversion Rate
shall again be adjusted to the Conversion Rate which would then be in effect if such dividend or distribution had not been declared. 
  

 31 








 (b) If the Company, at any time or from time to time while any of the Notes are outstanding,
issues to all or substantially all holders of the Common Stock any rights or warrants entitling them for a period of not more than 45 calendar days after date of such issuance to subscribe for or purchase shares of the Common Stock at a price
per share less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend Date for such issuance, the Conversion Rate shall be
adjusted based on the following formula: 
  

									
	CR1	 	=	  	CR0 x	 	 OS0 + X
	 	
	 	  	 	OS0 + Y	 	

 where 
  

					
	CR0	  	=	  	The Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such issuance;
			
	CR1	  	=	  	The Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	OS0	  	=	  	The number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date;
			
	X	  	=	  	The total number of shares of Common Stock issuable pursuant to such rights or warrants; and
			
	Y	  	=	  	The number of shares of Common Stock equal to the aggregate price payable to exercise such rights or warrants divided by the average of the Last Reported Sale Prices of
the Common Stock over the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement of the issuance of such rights or warrants.

 Such adjustment shall become effective immediately after the open of business on the Ex-Dividend Date
for such issuance. To the extent such rights or warrants are not exercised prior to their expiration or termination, the Conversion Rate shall be readjusted to the Conversion Rate which would be in effect had the adjustments made upon the issuance
of such rights or warrants been made on the basis of the delivery of only the number of shares of Common Stock actually delivered. In the event that such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the
Conversion Rate which would then be in effect if the date fixed for the determination of shareholders entitled to receive such rights or warrants had not been fixed. For the purposes of this Section 4.04(b), in determining whether any
rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than the average of the Last Reported Sale Prices of Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately
preceding the date of announcement of such issuance, and in determining the aggregate exercise price payable for such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights or warrants and
any amount payable on the exercise thereof, with the value of such consideration, if other than cash, as shall be determined by the Board of Directors. 
 (c) If the Company, at any time or from time to time while the Notes are outstanding, distributes shares of any class of capital stock of the Company, evidences of its indebtedness, other assets or
property of the Company or rights or warrants to acquire the Company’s capital stock or other securities to all or substantially all holders of its Common Stock, excluding: 
 (i) dividends or distributions and rights or warrants as to which an adjustment was effected pursuant to
Section 4.04(a) or Section 4.04(b); 
  

 32 








 (ii) dividends or distributions paid exclusively in cash (as set forth below
in Section 4.04(d)); and 
 (iii) Spin-Offs to which the provisions set forth below in this
Section 4.04(c) shall apply; 
 then the Conversion Rate shall be adjusted based on the following formula: 
  

									
	CR1	 	=	  	CR0 x	 	 SP0
	 	
	 	  	 	SP0 - FMV	 	

 where 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	SP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend
Date for such distribution; and
			
	FMV	  	=	  	the fair market value (as determined by the Board of Directors) of the shares of capital stock, evidences of indebtedness, assets, property, rights or warrants distributed with
respect to each outstanding share of the Common Stock on the Ex-Dividend Date for such distribution.

 Such adjustment shall become effective immediately after the open of business on
the Ex-Dividend Date for such distribution. If the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes of this Section 4.04(c) 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 average of the Last Reported Sale Prices of the Common Stock. Notwithstanding the foregoing, if “FMV” (as
defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing adjustment, each Holder of Notes shall receive, at the same time and upon the same terms as holders of the Common Stock, the
amount and kind of securities, assets and property such Holder would have received as if such Holder owned a number of shares of Common Stock equal to, for each $1,000 principal amount of Notes, the Conversion Rate in effect on the record date for
the distribution of the securities, assets or property. 
  

 33 








 With respect to an adjustment pursuant to this Section 4.04(c) where there has been a payment of
a dividend or other distribution on the Common Stock of shares of capital stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit and such dividend or distribution is listed for trading on a
securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula: 
  

									
	CR1	 	=	  	CR0 x	 	 FMV0 + MP0
	 	
	 	  	 	MP0	 	

 where 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the end of the Valuation Period (as defined below);
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the end of the Valuation Period;
			
	FMV0	  	=	  	the average of the Last Reported Sale Prices of the capital stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock
(determined for purposes of the definition of Last Reported Sale Price as if such capital stock or similar equity interest were the Common Stock) over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of the
Spin-Off (the “Valuation Period”); and
			
	MP0	  	=	  	the average of the Last Reported Sale Prices of Common Stock over the Valuation Period.

 The adjustment to the Conversion Rate under the preceding paragraph will occur on the last day of the
Valuation Period; provided that in respect of any conversion during the Valuation Period, references above to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of
such Spin-Off and the Conversion Date in determining the applicable Conversion Rate. 
 For the purposes of this
Section 4.04(c) (and subject in all respects to Section 4.12), rights or warrants distributed by the Company to all holders of its Common Stock entitling them to subscribe for or purchase shares of the Company’s capital
stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (a “Trigger Event”): (1) are deemed to be transferred with such shares of Common Stock;
(2) are not exercisable; and (3) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 4.04(c), (and no adjustment to the Conversion Rate under
this Section 4.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion
Rate shall be made under this Section 4.04(c). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights
or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date of such deemed
distribution (in which case the original rights or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders). In addition, in the event of any distribution or deemed distribution of rights or warrants, or
any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this  

  

 34 








 
Section 4.04(c) was made, (1) in the case of any such rights or warrants which shall all have been redeemed or purchased without exercise by any Holders thereof, upon such final
redemption or repurchase (x) the Conversion Rate shall be readjusted as if such rights or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or
Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by holders of Common Stock with respect to such rights or warrants (assuming each such holder had retained such
rights or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights or warrants which shall have expired or been terminated without exercise by any holders thereof, the
Conversion Rate shall be readjusted as if such rights and warrants had not been issued. 
 For the purposes of this
Section 4.04(c) and subsections (a) and (b) of this Section 4.04, any dividend or distribution to which this Section 4.04(c) applies which also includes one or both of: 
 (A) a dividend or distribution of shares of Common Stock to which Section 4.04(a) applies (the “Clause A
Distribution”); and 
 (B) a dividend or distribution of rights or warrants to which
Section 4.04(b) applies (the “Clause B Distribution”), 
 then (1) such dividend or distribution, other than
the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 4.04(c) applies (the “Clause C Distribution”) and any Conversion Rate adjustment required by
this Section 4.04(c) with respect thereto shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by
Section 4.04(a) and Section 4.04(b) with respect thereto shall then be made, except that, if determined by the Company, (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B
Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately
prior to the open of business on such Ex-Dividend Date or such effective date” within the meaning of Section 4.04(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date” within the meaning of
Section 4.04(b). 
 (d) If the Company makes any cash dividend or distribution to all or substantially all holders
of Common Stock, the Conversion Rate shall be adjusted based on the following formula: 
  

									
	CR1	 	=	  	CR0 x	 	 SP0
	 	
	 	  	 	SP0 - C	 	

 where 
  

					
	CR0	  	=	  	The Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;

  

 35 









					
	CR1	  	=	  	The Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	  	=	  	The Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and
			
	C	  	=	  	The amount in cash per share the Company distributes to holders of the Common Stock.

 In the case of an adjustment pursuant to this Section 4.04(d), such adjustment shall
become effective immediately after the open of business on the Ex-Dividend Date for the relevant dividend or distribution. If the portion of the cash so distributed applicable to one share of the Common Stock is equal to or greater than the Last
Reported Sale Price of a share of Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution, in lieu of the adjustment set forth above, adequate provision shall be made so that each Holder of Notes
shall have the right to receive on the date on which such cash dividend or distribution is distributed to holders of Common Stock, for each $1,000 principal amount of Notes, the amount of cash such Holder would have received had such Holder owned a
number of shares of Common Stock equal to the Conversion Rate in effect immediately prior to the Ex-Dividend Date for such distribution. 
 (e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for Common Stock, to the extent that the cash and value of any other consideration included in
the payment per share of Common Stock exceeds the Last Reported Sale Price per share of Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion
Rate shall be increased based on the following formula: 
  

							
	CR1	 	=	  	CR0 x	 	 AC + (SP1 x OS1)

	 	  	 	OS0 x SP1

 where 

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date
such tender or exchange offer expires;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such
tender or exchange offer expires;
			
	AC	  	=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares purchased in such tender or exchange
offer;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires;

  

 36 









					
	OS1	  	=	  	the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase of all shares accepted for
purchase or exchange in such tender or exchange offer); and
			
	SP1	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on the Trading Day next succeeding the date such
tender or exchange offer expires.

 The adjustment to the Conversion Rate under this Section 4.04(e) shall occur as of the
close of business on the tenth Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that in respect of any conversion within 10 Trading Days immediately
following, and including, the expiration date of any tender or exchange offer, references with respect to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the expiration date of such tender or
exchange offer and the Conversion Date in determining the applicable Conversion Rate. 
 (f) The Company from time to time may
increase the Conversion Rate by any amount for any period of time of at least 20 Business Days, so long as the increase is irrevocable during the period and the Board of Directors shall have made a determination that such increase would be in the
best interests of the Company, which determination shall be conclusive. Whenever the Conversion Rate is increased pursuant to this Section 4.04(f), the Company shall mail to Holders of record of the Notes a notice of the increase at
least one day prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect. 
 (g) The Company may (but shall not be required to) increase the Conversion Rate, in addition to any adjustments pursuant to
Section 4.04(a), 4.04(b), 4.04(c), 4.04(d), 4.04(e) or 4.04(f), if the Board of Directors considers such increase to be advisable to avoid or diminish any income tax to holders of Common Stock or rights
to purchase Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar event. 
 (h) All calculations under this Article 4 shall be made by the Company and shall be made to the nearest cent (including, in the case of any adjustment to the Conversion Rate, the resulting adjustment to the Conversion Price) or
to the nearest one ten-thousandth of a share. No adjustment shall be required to be made for the Company’s issuance of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or rights to purchase shares of
Common Stock or such convertible or exchangeable securities, other than as provided in this Section 4.04 and in Section 4.11 hereof. 
 (i) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any Conversion Agent an Officers’ Certificate setting forth the Conversion Rate
after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have
knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate

  

 37 








 
of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted
Conversion Rate and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Rate to each Holder of the Notes. Failure to deliver such notice shall not affect the legality or validity of any
such adjustment. 
 (j) For purposes of this Section 4.04, the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable in
respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 
 (k) Notwithstanding the foregoing, if
the application of the foregoing formulas set forth in this Section 4.04 would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate shall be made (other than as a result of a reverse share split or share
combination). 
 (l) Notwithstanding anything to the contrary in this Article 4, no adjustment to the Conversion
Rate shall be made: 
 (i) upon the issuance of any shares of Common Stock pursuant to any present or future plan
providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan; 
 (ii) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or
future employee, director or consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries; 
 (iii) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (ii) above and outstanding as
of the date the Notes were first issued; 
 (iv) for a change in the par value of the Common Stock; or

 (v) for accrued and unpaid interest on the Notes. 
 (m) If a Conversion Rate adjustment becomes effective on any Ex-Dividend Date as described above, and a Holder that has converted its Notes
on or after such Ex-Dividend Date and on or prior to the related record date would be treated as the record holder of shares of Common Stock as of the related Conversion Date as set forth in Section 4.02(e) based on an adjusted
Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions above, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder. Instead, such Holder
shall be deemed to be the record owner of shares of Common Stock on an unadjusted basis on such Conversion Date and participate in the related dividend, distribution or other event giving rise to such adjustment. 
  

 38 








 SECTION 4.05 Certain Other Adjustments. Whenever a provision of this Indenture
requires the calculation of Last Reported Sale Prices or Daily VWAP over a span of multiple days, the Board of Directors will make appropriate adjustments to such Last Reported Sale Prices or Daily VWAP, the Conversion Rate, or the amount due upon
conversion to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date of the event occurs, at any time during the period from which such Last
Reported Sale Prices or Daily VWAP are to be calculated. 
 SECTION 4.06 Adjustments Upon Certain Fundamental Changes.
(a) If a Make-Whole Fundamental Change occurs and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under the circumstances described below, increase the Conversion Rate for the Notes so
surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”) as described below. A conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole
Fundamental Change if the notice of conversion of the Notes is received by the Conversion Agent from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, the Business Day immediately prior to the related
Fundamental Change Purchase Date (or, in the case of an event that would have been a Fundamental Change but for the proviso in clause (2) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such
Make-Whole Fundamental Change). 
 (b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental
Change, the Company shall have the right to deliver, in lieu of shares of Common Stock, including the Additional Shares, cash or a combination of cash and shares of Common Stock as provided under Section 4.03(a); provided,
however, that if the consideration for the Common Stock in any Make-Whole Fundamental Change described in clause (2) of the definition of Fundamental Change is comprised entirely of cash, then, for any conversion of Notes following the
Effective Date of such Make-Whole Fundamental Change, the amounts deliverable by the Company shall be calculated based solely on the Stock Price for the Make-Whole Fundamental Change and shall be deemed to be an amount equal to the applicable
Conversion Rate (including any adjustment for Additional Shares described in this Section) multiplied by such Stock Price. In such event, the amounts deliverable by the Company shall be determined and paid to holders in cash on the third Business
Day following the Conversion Date. 
 (c) The number of Additional Shares, if any, by which the Conversion Rate will be
increased will be determined by reference to the table attached as Schedule A hereto, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the “Stock
Price”) paid (or deemed paid) per share of the Common Stock in the Make-Whole Fundamental Change. If the holders of the Common Stock receive only cash in a Make-Whole Fundamental Change described in clause (2) of the definition of
Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading-Day period ending on, and including, the Trading
Day preceding the Effective Date of the Make-Whole Fundamental Change. 
  

 39 








 The exact Stock Prices and Effective Dates may not be set forth in the table in
Schedule A, in which case: 
 (i) If the Stock Price is between two Stock Prices in the table or the
Effective Date is between two Effective Dates in the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the earlier
and later Effective Dates, as applicable, based on a 365-day year. 
 (ii) If the Stock Price is greater than
$[            ] per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table in Schedule A pursuant to subsection (d) below),
no Additional Shares shall be added to the Conversion Rate. 
 (iii) If the Stock Price is less than
$[            ] per share (subject to adjustments in the same manner as the Stock Prices set forth in the column headings of the table in Schedule A pursuant to subsection
(d) below), no Additional Shares shall be added to the Conversion Rate. 
 Notwithstanding the foregoing, in no event shall
the Conversion Rate exceed [            ] shares of Common Stock per $1,000 principal amount of Notes, subject to adjustments in the same manner as the Conversion Rate as set forth in
Section 4.04. 
 (d) The Stock Prices set forth in the column headings of the table in Schedule A hereto shall be
adjusted as of any date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall 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 such 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 such table shall be adjusted in the same
manner as the Conversion Rate as set forth in Section 4.04. 
 (e) The Company shall notify the Holders of Notes of
the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date. 
 SECTION 4.07 Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale. (a) If any of the following events occur:

 (i) any recapitalization or reclassification of, or change in, the Common Stock (other than changes resulting
from a subdivision or combination); 
 (ii) a consolidation, merger or combination involving the Company; or

 (iii) a sale, lease or other transfer to a third party of the consolidated assets of the Company and its
Subsidiaries substantially as an entirety, or 
 (iv) any statutory share exchange; 
  

 40 








 in each case as a result of which the Common Stock would be converted into, or exchanged for, or would be
reclassified or changed into, stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “Merger Event”), then at the effective time of such Merger Event, the Company or the
successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture) providing that at and
after the effective time of such Merger Event, the right to convert a Note will be changed into a right to convert such Note as set forth in this Indenture into the kind and amount of shares of stock, other securities or other property or assets
(including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Conversation Rate prior to such Merger Event would have owned or been entitled to receive (the “Reference Property”, with
each “unit of Reference Property” meaning the type and amount of Reference Property that a holder of one share of Common Stock is entitled to receive) upon such Merger Event; provided, however, that at and after the
effective time of the Merger Event the conversion obligation shall be calculated and settled in accordance with Section 4.03 such that (i) the amount payable in cash upon conversion of the Notes as set forth under
Section 4.03 will continue to be payable in cash, (ii) the number of shares of Common Stock (if the Company elects Physical Settlement or Combination Settlement) deliverable upon conversion of the Notes under
Section 4.03 will be instead deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have been entitled to receive in such Merger Event and (iii) the Daily VWAP will be
calculated based on the value of a unit of Reference Property. 
 If, as a result of the Merger Event, each share of Common
Stock is converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then (x) the Reference Property into which the Notes will be convertible
will be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election, and (y) the unit of Reference Property for purposes of the foregoing sentence
shall refer to the consideration referred to in clause (x) attributable to one share of Common Stock. 
 The Company shall
not become a party to any such Merger Event unless its terms are consistent with this Section 4.07(a). 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 4 in the judgment of the Board of Directors or the board of directors of the successor Person. If, in the case of any such recapitalization, reclassification, change, consolidation, merger,
combination, sale, lease, other transfer or statutory share exchange, the Reference Property receivable thereupon by a holder of Common Stock includes shares of stock, securities or other property or assets (including cash or any combination
thereof) of a Person other than the successor or purchasing Person, as the case may be, in such reorganization, reclassification, change, consolidation, merger, combination, sale, lease, other transfer or statutory share exchange, then such
supplemental indenture shall also be executed by such other Person. 
 (b) The Company shall cause notice of the execution of
such supplemental indenture to be mailed to each Holder, at the address of such Holder as it appears on the register of the Notes maintained by the Note Registrar, within 20 calendar days after execution thereof. Failure to deliver such notice shall
not affect the legality or validity of such supplemental indenture. The

  

 41 








 
above provisions of this Section 4.07 shall similarly apply to successive reclassifications, changes, consolidations, mergers, combinations, sales and conveyances. If this
Section 4.07 applies to any Merger Event, Section 4.04 shall not apply. 
 SECTION 4.08 Taxes on
Shares Issued. The Company will pay any documentary, stamp or similar issue or transfer tax due on the issue or delivery of shares of Common Stock on conversion of Notes pursuant hereto; provided, however, that if such documentary, stamp
or similar issue or transfer tax is due because the Holder of such Notes has requested that shares of Common Stock be issued in a name other than that of the Holder of the Notes converted, then such taxes will be paid by the Holder, and the Company
shall not be required to issue or deliver any stock certificate evidencing such shares unless and until the Holder shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has
been paid. 
 SECTION 4.09 Reservation of Shares; Shares to be Fully Paid; Compliance With Governmental Requirements; Listing
of Common Stock. The Company shall reserve, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to satisfy conversion of the Notes from time to time as such Notes are presented for conversion
(assuming that, at the time of the computation of such number of shares or securities, all such Notes would be converted by a single Holder and that Physical Settlement would apply). 
 The Company covenants that all shares of Common Stock that may be issued upon conversion of Notes shall be newly issued shares or treasury
shares, shall be duly authorized, validly issued, fully paid and non-assessable and shall be free from preemptive rights and free from any tax, lien or charge (other than those created by the Holder). 
 The Company shall list or cause to have quoted any shares of Common Stock to be issued upon conversion of Notes on each national securities
exchange or over-the-counter or other domestic market on which the Common Stock is then listed or quoted. 
 SECTION 4.10
Responsibility of Trustee. The Trustee and any Conversion Agent shall not at any time be under any duty or responsibility to any Holder of Notes to determine or calculate the Conversion Rate, to determine whether any facts exist which may
require any adjustment of the Conversion Rate, or to confirm the accuracy of any such adjustment when made or the appropriateness of the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The
Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock or of any other securities or property that may at any time be issued or delivered upon the
conversion of any Notes; and the Trustee and the Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares
of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Notes for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this
Article 4. The rights, privileges, protections, immunities and benefits given to the Trustee, including without limitation its right to be compensated, reimbursed, and indemnified, are extended to, and shall be enforceable by, the
Trustee in each of its capacities hereunder, including its capacity as Conversion Agent and if it is so appointed by the Company and accepts such appointment, as Bid Solicitation Agent. 
  

 42 








 SECTION 4.11 Notice to Holders Prior to Certain Actions. In case: 
 (a) the Company shall declare a dividend (or any other distribution) on its Common Stock that would require an adjustment in the Conversion
Rate pursuant to Section 4.04; or 
 (b) the Company shall authorize the granting to the holders of all or
substantially all of its Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants that would require an adjustment in the Conversion Rate pursuant to Section 4.04 or
Section 4.12 hereof; or 
 (c) of any reclassification or reorganization of the Common Stock of the Company (other
than a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the
sale, lease or transfer of all or substantially all of the assets of the Company and its consolidated Subsidiaries; or 
 (d) of
the voluntary or involuntary dissolution, liquidation or winding up of the Company or any of its Subsidiaries; 
 then, in each case (unless
notice of such event is otherwise required pursuant to another provision of this Indenture), the Company shall cause to be filed with the Trustee and the Conversion Agent and to be mailed to each Holder of Notes at such Holder’s address
appearing on a list of Holders of Notes, which the Company shall provide to the Trustee, as promptly as practicable but in any event at least 10 calendar days prior to the applicable date hereinafter specified, a notice stating (x) the date on
which a record is to be taken for the purpose of such dividend (or any other distribution) or rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend,
distribution or rights or warrants are to be determined, or (y) the date on which such reclassification, reorganization, consolidation, merger, sale, lease, transfer, dissolution, liquidation or winding up is expected to become effective or
occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, reorganization, consolidation, merger,
sale, transfer, dissolution, liquidation or winding up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such dividend (or any other distribution), reclassification, reorganization, consolidation,
merger, sale, transfer, dissolution, liquidation or winding up. 
 SECTION 4.12 Stockholder Rights Plan. Each share of
Common Stock issued upon conversion of Notes pursuant to this Article 4 shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such
legends, if any, in each case as may be provided by the terms of any stockholder rights plan adopted by the Company, as the same may be amended from time to time. Notwithstanding the foregoing, if prior to any conversion such rights have separated
from the shares of Common Stock in accordance with the provisions of the applicable stockholder 
  

 43 








 
rights agreement, the Conversion Rate shall be adjusted at the time of separation as if the Company had distributed to all holders of the Common Stock, shares of the Company’s capital stock,
evidences of indebtedness, assets, property, rights or warrants as described in Section 4.04(c) above, subject to readjustment in the event of the expiration, termination or redemption of such rights. 
 ARTICLE 5 
 DEFAULTS AND REMEDIES 
 SECTION 5.01 Events of Default. Each of the following shall be an “Event
of Default”: 
 (a) the Company defaults in the payment of interest, including any Additional Interest, on any Note
when the same becomes due and payable and such default continues for a period of 30 days, whether or not such payment is prohibited pursuant to Article 8; 
 (b) the Company defaults in the payment of the principal of any Note when the same becomes due and payable at its Maturity, upon acceleration, upon any required repurchase, or otherwise, whether or not
such payment is prohibited pursuant to Article 8; 
 (c) failure by the Company to comply with its obligation to convert
the Notes in accordance with the Indenture upon exercise of a Holder’s conversion right in accordance with Article 4 hereof, whether or not prohibited pursuant to Article 8; 
 (d) failure by the Company to provide a Fundamental Change Company Notice pursuant to Section 3.01(b) or notice of a specified
corporate transaction required by Section 4.01(a)(iii) or Section 4.01(a)(iv) in accordance with the relevant Section, in each case when due; 
 (e) failure by the Company to comply with its obligations under Section 6.01 hereof; 
 (f) the Company fails to perform or observe with any of the covenants or agreements contained in the Notes or Indenture (other than a default set forth in clauses (a), (b), (c), (d) or
(e) above) for 30 days after written notice to the Company from the Trustee or to the Trustee from the Holders of at least 25% in principal amount of the Notes then outstanding; 
 (g) the entry by a court of competent jurisdiction of one or more judgments, orders or decrees against the Company or any subsidiary of the
Company (other than a Securitization Subsidiary) or any of their respective property or assets in an aggregate amount in excess of $50.0 million, which judgments, orders or decrees have not been vacated, discharged, satisfied or stayed pending
appeal within 30 days from the entry thereof and with respect to which legal enforcement proceedings have been commenced; 
 (h)
default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by the Company or any subsidiary of the Company (other than a Securitization
Subsidiary) (or the payment of which is guaranteed by the Company or any subsidiary of the Company), which default is caused by a failure to pay principal of or premium, if any, on such indebtedness upon

  

 44 








 
its stated maturity or which default results in the acceleration of such indebtedness prior to its express maturity and the principal amount of any such indebtedness, together with the principal
amount of any other such indebtedness the maturity of which has been so accelerated, aggregates $50.0 million or more and such acceleration has not been rescinded or annulled or such indebtedness discharged in full within 30 days;

 (i) the Company or any Significant Subsidiary of the Company pursuant to or within the meaning of any Bankruptcy Law:

 (A) commences a voluntary case, 
 (B) consents to the entry of an order for relief against it in an involuntary case, 
 (C) consents to the appointment of a Bankruptcy Custodian of it or for all or substantially all of its property, or

 (D) makes a general assignment for the benefit of its creditors; and 
 (j) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that remains unstayed and in effect for
90 days and that: 
 (A) is for the relief against the Company or any Significant Subsidiary of the Company
as debtor in an involuntary case, 
 (B) appoints a Bankruptcy Custodian of the Company or any Significant
Subsidiary of the Company or a Bankruptcy Custodian for all or substantially all of the property of any Significant Subsidiary of the Company, or 
 (C) orders the liquidation of the Company or any Significant Subsidiary of the Company. 
 SECTION 5.02 Additional Interest. Notwithstanding any provisions of the Indenture to the contrary, if the Company so elects, the sole remedy for an Event of Default relating to any obligation to
file documents and reports with the Trustee as required by Section 314(a)(1) of the Trust Indenture Act or Section 9.06 of this Indenture shall for the first 180 days following the occurrence of such Event of Default consist
exclusively of the right to receive additional interest on the Notes at a rate equal to 0.25% per annum of the principal amount of the Notes outstanding for each during the 90-day period beginning on, and including, the occurrence of such Event
of Default during which such Event of Default is continuing, and at a rate equal to 0.50% per annum of the principal amount of the Notes outstanding for each day from the 91st day until the 364th day during which such Event of Default is continuing (in each case, “Additional Interest”). In order
to elect to pay Additional Interest as the sole remedy during the first 364 days after the occurrence of an Event of Default described in the preceding sentence, the Company must give notice to Holders of the Notes, the Trustee and the Paying Agent
of such election on or prior to the close of business on the Business Day before the date on which such Event of Default would occur and on or prior to the close of business on the 91st day after the date on which such Event of Default first occurs. If the Company so elects, such Additional

  

 45 








 
Interest shall be payable in the same manner and on the same dates as the stated interest payable on the Notes. Upon the failure to timely give all Holders, the Trustee and the Paying Agent such
notice, the Notes will be subject to immediate acceleration as provided in Section 5.03 of this Indenture. On the 365th day after such Event of Default occurs (if such Event of Default is not cured or waived prior to such 365th day), the
Notes shall be subject to acceleration as provided in Section 5.03 of the Indenture. This Section 5.02 shall not affect the rights of Holders of Notes in the event of the occurrence of any other Event of Default. Whenever in
the Indenture there is mentioned, in any context, the payment of interest on, or in respect of, any Note, such mention shall be deemed to include mention of the payment of Additional Interest provided for in this Section 5.02 to the
extent that, in such context, Additional Interest is, was or would be payable in respect thereof pursuant to the provisions of this Section 5.02, and express mention of the payment of Additional Interest (if applicable) in any provision
shall not be construed as excluding Additional Interest in those provisions where such express mention is not made. 
 SECTION
5.03 Acceleration. Subject to the provisions of Section 5.02, if an Event of Default occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the outstanding
Notes by notice to the Company and the Trustee, may, and the Trustee at the request of such holders shall, declare 100% of the principal of and accrued and unpaid interest on all the Notes to be due and payable. Upon such a declaration of
acceleration, all principal and accrued and unpaid interest (including any Additional Interest) on the Notes will be due and payable immediately. However, upon an Event of Default arising out of Sections 5.01(i) or 5.01(j), the
aggregate principal amount and accrued and unpaid interest (including any Additional Interest) will be due and payable immediately, without any declaration, notice or other act on the part of the Trustee or Holder. The Holders of a majority in
principal amount of the then outstanding Notes affected by such Event of Default, by written notice to the Trustee, may rescind an acceleration and its consequences (other than nonpayment of principal of or premium, if any, or interest on or any
Additional Interest with respect to the Notes) if the rescission would not conflict with any judgment or decree and if all existing Events of Default with respect to the Notes have been cured or waived, except nonpayment of principal, premium, if
any, interest or any Additional Interest that has become due solely because of the acceleration. 
 SECTION 5.04 Payments of
Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of Section 5.01 shall have occurred and be continuing, the Company shall, upon demand of the Trustee, pay to it, for the benefit of
the holders of the Notes, the whole amount then due and payable on the Notes for principal, premium, if any, and interest, with interest on any overdue principal, premium, if any, interest, at the rate borne by the Notes at such time, and, in
addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 11.06. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as
trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the
Notes and collect the monies adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated. 
  

 46 








 In the event there shall be pending proceedings for the bankruptcy or for the reorganization
of the Company or any other obligor on the Notes under any Bankruptcy Law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of
the Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company or
such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the
provisions of this Section 5.04, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal premium, if any, and accrued and unpaid interest in
respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee (including any
claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders of Notes allowed in such judicial proceedings relative to the Company or any other obligor on the Notes, its or
their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due the Trustee under
Section 11.06; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders of Notes to make such payments to the Trustee, as administrative
expenses, and, in the event that the Trustee shall consent to the making of such payments directly to the Holders of Notes, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including
agent’s and counsel fees and expenses, and including any other amounts due to the Trustee under Section 11.06 hereof, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation,
expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and
other property that the holders of the Notes may be 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 accept or adopt on behalf of any Holder of
Notes any plan of reorganization, arrangement, adjustment or composition affecting the Holder of Notes or the rights of any Holder of Notes thereof, or to authorize the Trustee to vote in respect of the claim of any Holder of Notes in any such
proceeding. 
 All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by
the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express
trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the holders of the Notes.

  

 47 








 In any proceedings brought by the Trustee (and in any proceedings involving the
interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the holders of the Notes, and it shall not be necessary to make any holders of the Notes parties to any such
proceedings. 
 In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall
have been discontinued or abandoned because of such waiver or rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Holders of Notes, and the Trustee
shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders of Notes, and the Trustee shall continue as though no
such proceeding had been instituted. 
 SECTION 5.05 Application of Monies Collected by Trustee. Any monies collected by
the Trustee pursuant to this Article 5 with respect to the Notes shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping
thereon the payment, if only partially paid, and upon surrender thereof, if fully paid: 
 First, to the payment
of all amounts due the Trustee under Section 11.06; 
 Second, in case the principal of the
outstanding Notes shall not have become due and be unpaid, to the payment of interest on the Notes, including any Additional Interest, in default in the order of the date due of the installments of such interest, with interest (to the extent that
such interest has been collected by the Trustee) upon the overdue installments of interest at the rate borne by the Notes at such time, such payments to be made ratably to the Persons entitled thereto; 
 Third, in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to
the payment of the whole amount including the payment of the Fundamental Change Purchase Price and the cash component of the Conversion Obligation, if any, then owing and unpaid upon the Notes for principal and premium, if any, and interest,
including any Additional Interest, with interest on the overdue principal and premium, if any, and (to the extent that such interest has been collected by the Trustee) upon overdue installments of interest at the rate borne by the Notes at such
time, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal and premium, if any, and interest without preference or priority of principal and premium,
if any, over interest, or of interest over principal and premium, if any, or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal and premium, if any,
and accrued and unpaid interest; and 
 Fourth, to the payment of the remainder, if any, to the Company.

 SECTION 5.06 Proceedings by Holders of Notes. No holder of any Note shall have any right by virtue of or by availing
of any provision of this Indenture to institute any suit, action

  

 48 








 
or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other
remedy hereunder, unless such holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as hereinbefore provided, and unless also the holders of not less than 25% in aggregate principal
amount of the Notes then outstanding shall have made written request to the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such security or indemnity reasonably
satisfactory to it against any loss, liability or expense to be incurred therein or thereby, and the Trustee for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such
action, suit or proceeding and no direction that, in the opinion of the Trustee, is inconsistent with such written request shall have been given to the Trustee by the holders of a majority in principal amount of the Notes outstanding within such
60-day period pursuant to Section 5.09; it being understood and intended, and being expressly covenanted by the taker and holder of every Note with every other taker and holder and the Trustee that no one or more Noteholders shall have
any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other Noteholder (it being understood that the Trustee does not have an affirmative duty to ascertain
whether or not such actions or forbearances are unduly prejudicial to such Noteholders), or to obtain or seek to obtain priority over or preference to any other such holder, or to enforce any right under this Indenture, except in the manner herein
provided and for the equal, ratable and common benefit of all Noteholders (except as otherwise provided herein). For the protection and enforcement of this Section 5.06, each and every Noteholder and the Trustee shall be entitled to such
relief as can be given either at law or in equity. 
 Notwithstanding any other provision of this Indenture and any provision of
any Note, the right of any Holder of Notes to (i) receive payment of principal of and premium, if any, and interest and any Additional Interest when due, (ii) receive payment or delivery of the consideration due upon conversion,
(iii) receive the Fundamental Change Purchase Price when due, or (iv) bring suit for the enforcement of any of (i), (ii) and (iii) above, is absolute and unconditional and shall not be impaired or affected without the consent of
such Holder. 
 Anything in this Indenture or the Notes to the contrary notwithstanding, the holder of any Note, without the
consent of either the Trustee or the holder of any other Note, on its own behalf and for its own benefit, may enforce, and may institute and maintain any proceeding suitable to enforce, its rights of conversion as provided herein. 
 SECTION 5.07 Proceedings by Trustee. In case of an Event of Default the Trustee may in its discretion proceed to protect and enforce
the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the
specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

 SECTION 5.08 Remedies Cumulative and Continuing. Except as provided in the last paragraph of Section 2.07
and Section 5.02, all powers and remedies given by this Article 5 to

  

 49 








 
the Trustee or to the Noteholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the
holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any holder of any of the Notes to
exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or any acquiescence therein; and, subject to the provisions of
Section 5.06, every power and remedy given by this Article 5 or by law to the Trustee or to the Noteholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Noteholders.

 SECTION 5.09 Direction of Proceedings and Waiver of Defaults by Majority of Holders of Notes. The Holders of a
majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 12.04 shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to
the Trustee or exercising any trust or power conferred on the Trustee with respect to Notes; provided, however, that (a) such direction shall not be in conflict with any rule of law or with this Indenture, and (b) the Trustee
may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other holder or that would involve the
Trustee in personal liability. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 12.04 by notice to the Trustee may waive an existing or past Default or
Event of Default with respect to such Notes and its consequences, except (1) a continuing Default or Event of Default in the payment of premium, accrued and unpaid interest or any accrued and unpaid Additional Interest on, or the principal
(including any Fundamental Change Purchase Price) of, the Notes when due, (2) a continuing Default or Event of Default in the payment or delivery of any consideration due upon conversion of any Note, or (3) a continued Default in respect
of a provision that under Article 7 cannot be amended or supplemented without the consent of each Holder affected. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to
have been cured for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by
this Section 5.09, said Default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event
of Default or impair any right consequent thereon. 
 SECTION 5.10 Notice of Defaults. The Trustee shall, within
90 days after the occurrence and continuance of a Default or Event of Default of which a Responsible Officer has actual knowledge, mail to all Noteholders as the names and addresses of such holders appear upon the Note Register, notice of all
Defaults or Events of Default known to a Responsible Officer, unless such Defaults or Events of Default shall have been cured or waived before the giving of such notice; and provided that, except in the case of a Default or in the payment of
the principal of, or premium, if any, accrued and unpaid interest including any accrued and unpaid Additional Interest on any of the Notes, including without limiting the generality of the foregoing any Default or Event of Default in the payment of
any Fundamental Change Purchase Price, or a Default or Event of Default in the payment or delivery of consideration due upon 
  

 50 








 
conversion of the Notes, then in any such event the Trustee shall be protected in withholding such notice if and so long as a committee of Responsible Officers of the Trustee in good faith
determine that the withholding of such notice is in the interests of the Noteholders. 
 SECTION 5.11 Undertaking to Pay
Costs. All parties to this Indenture agree, and each holder of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable
costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this
Section 5.11 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than 10% in principal amount of the
Notes at the time outstanding determined in accordance with Section 12.04, or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of or premium, if any, accrued and unpaid interest, if any, on any
Note (including, but not limited to, the Fundamental Change Purchase Price with respect to the Notes being repurchased as provided in this Indenture) on or after the due date expressed or provided for in such Note or to any suit for the enforcement

 52 








 Any supplemental indenture authorized by the provisions of this Section 7.01 may
be executed by the Company and the Trustee without the consent of the Holders of any of the Notes at the time outstanding, notwithstanding any of the provisions of Section 7.02. 
 SECTION 7.02 Amendments, Supplements or Waivers With Consent of Holders. With the consent of the Holders of at least a majority in
aggregate principal amount of the Notes at the time outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), the Company, when authorized by the resolutions of the

 (j) make any change in this
Section 7.02 or Section 5.09, except to increase any such percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each Note so affected.

  

 53 








 Upon the written request of the Company, and upon the filing with the Trustee of evidence of
the consent of Noteholders as aforesaid and subject to Section 7.05, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties
or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. 
 It shall not be necessary for the consent of the Noteholders under this Section 7.02 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such
consent shall approve the substance thereof. After an amendment under this Indenture becomes effective, the Company shall mail to the holders a notice briefly describing such amendment. However, the failure to give such notice to all the holders, or
any defect in the notice, will not impair or affect the validity of the amendment. 
 SECTION 7.03 Effect of Supplemental
Indentures. Any supplemental indenture executed pursuant to the provisions of this Article 7 shall comply with the Trust Indenture Act, as then in effect; provided that this Section 7.03 shall not require such
supplemental indenture to be qualified under the Trust Indenture Act prior to the time such qualification is in fact required under the terms of the Trust Indenture Act or this Indenture has been qualified under the Trust Indenture Act, nor shall
any such qualification constitute any admission or acknowledgment by any party to such supplemental indenture that any such qualification is required prior to the time such qualification is in fact required under the terms of the Trust Indenture Act
or this Indenture has been qualified under the Trust Indenture Act. Upon the execution of any supplemental indenture pursuant to the provisions of this Article 7, this Indenture shall be and be deemed to be modified and amended in
accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the Noteholders shall thereafter be determined, exercised and enforced hereunder subject in
all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.

provisions of this Article 7.04 may, at the Company’s expense, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company or the Trustee shall so determine, new Notes
so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture may, at the Company’s expense, be prepared and executed by the Company,
authenticated by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section 14.10) and delivered in exchange for the Notes then outstanding, upon surrender of such Notes then outstanding. 
 SECTION 7.05 Evidence of Compliance of Supplemental Indenture to be Furnished to Trustee. In addition to the documents required by

 ARTICLE 8 
 SUBORDINATION OF NOTES 
 SECTION 8.01 Notes Subordinate to Senior
Indebtedness. The Company covenants and agrees, and each holder of a Note, whether upon original issue or upon registration of transfer, assignment or exchange hereof, by his acceptance thereof, likewise covenants and agrees, that, to the extent
and in the manner hereinafter set forth in this Article 8, the indebtedness represented by the Notes and the payment of the principal amount, premium, if any, any cash portion of the Conversion Obligation in respect of, and interest on
all Notes (including, but not limited to, the Fundamental Change Purchase Price with respect to the Notes subject to repurchase in accordance with Article 3 as provided in this Indenture) (collectively, the “Subordinated
Obligations”) are hereby expressly made subordinate and junior in right of payment to the prior payment in full in cash or other payment satisfactory to the holders of Senior Indebtedness of all Senior Indebtedness and that said
subordination is for the benefit of the holders of Senior Indebtedness and they and/or each of them severally may enforce such subordination. The Notes will be pari passu in right of payment to all Senior Subordinated Indebtedness of the
Company and senior in right of payment to all Subordinated Indebtedness of the Company. 
 SECTION 8.02 Payment Over of
Proceeds Upon Dissolution, Etc. In the event of (a) any dissolution, insolvency or bankruptcy case or proceeding, or any receivership, liquidation, reorganization or other similar case or proceeding in connection therewith, relative to the
Company or to its creditors, as such, or to its assets, or (b) any liquidation, dissolution or other winding up of the Company, in each case whether voluntary or involuntary and whether or not involving insolvency or bankruptcy, or (c) any
assignment for the benefit of creditors or any other marshaling of assets and liabilities of the Company upon any payment or distribution of the Company’s assets or securities, then and in any such event the holders of Senior Indebtedness shall
be entitled to receive payment in full in cash, or other payment satisfactory to the holders of Senior Indebtedness, of all amounts due or to become due on or in respect of all Senior Indebtedness before the holders of the Notes are entitled to
receive any payment or distribution on account of the Subordinated Obligations, and to that end the holders of Senior Indebtedness or their representative or representatives or the trustee or trustees under any indenture under which any instruments
evidencing any of such Senior Indebtedness may have been issued, shall be entitled to receive from the liquidating trustee or agent or other Person making such payment or distribution, whether a trustee in bankruptcy, a receiver or liquidating
trustee or otherwise, ratably according to the aggregate amounts remaining unpaid on account of the Senior Indebtedness held or represented by each, to the extent necessary to make payment in full in cash or other payment satisfactory to the holders
of Senior Indebtedness of all Senior Indebtedness remaining unpaid, for application to the payment thereof, any payment or distribution of any kind or character, whether in cash, property or securities, which may be payable or deliverable in respect
of the Subordinated Obligations in any such case, proceeding, dissolution, liquidation or other winding up or event, assignment or marshalling. 
 The consolidation of the Company with, or the merger of the Company with or into, another Person or the liquidation or dissolution of the Company following the sale, conveyance, transfer or lease of all
or substantially all of its properties and assets to another Person upon the terms and conditions set forth in Article 6 hereof shall not be deemed a dissolution, winding up,

  

 55 








 
liquidation, reorganization, assignment for the benefit of creditors or marshaling of assets and liabilities of the Company for the purposes of this Section 8.02 if the Person formed
by such consolidation or with or into which the Company is merged or which acquires by sale, conveyance, transfer or lease all or substantially all of such properties and assets, as the case may be, shall, as a part of such consolidation, merger,
sale, conveyance, lease or transfer, comply with the conditions set forth in Article 6 hereof. 
 SECTION 8.03 No
Payment When Senior Indebtedness in Default. (a) The Company may not make any payment of or distribution with respect to the Subordinated Obligations nor may the Company acquire, defease or repurchase any Notes if (i) a payment default on
any Senior Indebtedness has occurred and is continuing with respect thereto (unless and until such payment default shall have been cured or waived in writing by the holders of such Senior Indebtedness); or (ii) a default (other than a default
referred to in the preceding clause (i)) on any Designated Senior Indebtedness occurs and is continuing that permits holders of such Senior Indebtedness to accelerate the maturity thereof and either such default is the subject of judicial
proceedings or the Trustee receives a written notice of default thereof that blocks payment under the Notes from any Person who may give such notice pursuant to the instrument evidencing or document governing such Designated Senior Indebtedness (a
“Senior Indebtedness Default Notice”). If the Company receives a Senior Indebtedness Default Notice, then a similar notice received within nine months thereafter relating to the same default on the same issue of Senior Indebtedness
shall not be effective to prevent the payment or acquisition of the Notes for purposes of this Section 8.03. 
 The
Company may resume payment on the Notes and may acquire Notes for cash if and when (x) the default referred to in clause (i) or (ii) of the preceding paragraph above is cured or waived in writing or ceases to exist; or (y) in the
case of a default referred to in clause (ii) of the preceding paragraph, 179 or more days pass after the receipt by the Company of the Senior Indebtedness Default Notice, and this Article 8 otherwise permits the payment or
acquisition at that time. 
 Nothing contained in this Article 8 or elsewhere in this Indenture or in any of the
Notes shall prevent the conversion by a holder of any Notes into shares of Common Stock in accordance with the provisions for conversion of such Notes set forth in this Indenture. 
 (b) In the event of an acceleration of the Notes as a result of an Event of Default, then and in such event the Company shall promptly
notify holders of Senior Indebtedness of such acceleration. The Company may not pay, or make any distribution with respect to, the Notes until the earlier of (i) the passage of 120 or more days have passed after such acceleration occurs or
(ii) the payment in full in cash or other payment satisfactory to the holders of Senior Indebtedness of all Senior Indebtedness, and may thereafter pay, or make any distribution with respect to, the Notes if this Article 8 permits
the payment or distribution at that time. 
 (c) In the event that, notwithstanding the foregoing provisions, any payment or
distribution of any kind or character, whether in cash, property or securities (including, without limitation, by way of setoff or otherwise), prohibited by this Article 8, shall be received by the Trustee or the holders of the Notes
before all Senior Indebtedness is paid in full in cash or other payment satisfactory to the holders of such Senior Indebtedness, such payment or distribution

  

 56 








 
shall be held in trust for the benefit of and shall be paid over or delivered to the holders of Senior Indebtedness or their representative or representatives, or to the trustee or trustees under
any indenture pursuant to which any instruments evidencing any Senior Indebtedness may have been issued, as their respective interests may appear for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to
pay all Senior Indebtedness in full in cash or other payment satisfactory to the holders of such Senior Indebtedness, after giving effect to any concurrent payment or distribution, or provision therefor, to or for the holders of such Senior
Indebtedness. 
 SECTION 8.04 Payment Permitted If No Default. Nothing contained in this Article 8 or any
other provision relating to subordination elsewhere in this Indenture or in any of the Notes shall prevent the Company, at any time except in the circumstances described in Section 8.02 and Section 8.03, from making payments
at any time of the principal amount of the Notes, any cash portion of the Conversion Obligation, interest, the repurchase price with respect to Notes submitted for repurchase in accordance with Article 3, as the case may be, as provided
in this Indenture. 
 SECTION 8.05 Subrogation to Rights of Holders of Senior Indebtedness. Subject to the payment in
full of all Senior Indebtedness in cash, and until the Notes are paid in full, the holders of the Notes shall be subrogated (equally and ratably with the holders of all Senior Subordinated Indebtedness) to the rights of the holders of such Senior
Indebtedness to receive payments and distributions of cash, property and securities applicable to the Senior Indebtedness to the extent that payments and distributions otherwise payable to holders of Notes have been applied to the payment of Senior
Indebtedness as provided by this Article 8. For purposes of such subrogation, no payments or distributions to the holders of the Senior Indebtedness of any cash, property or securities to which the Holders of the Notes or the Trustee
would be entitled, except for the provisions of this Article 8, and no payments over pursuant to the provisions of this Article 8 to the holders of Senior Indebtedness by Holders of the Notes or the Trustee, shall, as among
the Company, its creditors other than holders of Senior Indebtedness and the Holders of the Notes, be deemed to be a payment or distribution by the Company to or on account of the Notes. 
 SECTION 8.06 Provisions Solely To Define Relative Rights. The provisions of this Article 8 are and are intended solely
for the purpose of defining the relative rights of the holders of the Notes on the one hand and the holders of Senior Indebtedness on the other hand. Nothing contained in this Article 8 or elsewhere in this Indenture or in the Notes is
intended to or shall (a) impair, as among the Company, its creditors other than holders of Senior Indebtedness and the holders of the Notes, the obligation of the Company, which is absolute and unconditional (and which, subject to the rights
under this Article 8 of the holders of Senior Indebtedness, is intended to rank equally with all other general obligations of the Company), to pay to the holders of the Notes the principal amount of the Notes, any cash portion of the
Conversion Obligation, interest, the repurchase price with respect to Notes submitted for repurchase in accordance with Article 3, as the case may be, as provided in this Indenture as and when the same shall become due and payable in
accordance with their terms; or (b) affect the relative rights against the Company of the holders of the Notes and creditors of the Company other than the holders of Senior Indebtedness; or (c) prevent the Trustee or the Holder of any Note
from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the 
  

 57 








 
rights, if any, under this Article 8 of the holders of Senior Indebtedness to receive cash, property and securities otherwise payable or deliverable to the Trustee or such holder. If
the Company fails, as a result of this Article 8, to pay to the holders of the Notes the principal amount of the Notes, any cash portion of the Conversion Obligation, interest, the repurchase price with respect to Notes submitted for
repurchase in accordance with Article 3, as the case may be, as provided in this Indenture as and when the same shall become due and payable in accordance with their terms, such failure shall still constitute a Default or an Event of Default.

 SECTION 8.07 Trustee to Effectuate Subordination. Each holder of a Note by his acceptance thereof authorizes and
directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article 8 and appoints the Trustee his attorney-in-fact for any and all such purposes. 

SECTION 8.08 No Waiver of Subordination Provisions. No right of any present or future holder of any Senior Indebtedness to enforce
subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any non-compliance by the
Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with. 
 Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Indebtedness may, at any time and from time to time, without the consent of or notice to the Trustee or the
holders of the Notes, without incurring responsibility to the holders of the Notes and without impairing or releasing the subordination provided in this Article 8 or the obligations hereunder of the holders of the Notes to the holders of
Senior Indebtedness, do any one or more of the following: (i) change the manner, place or terms of payment or extend the time of payment of, or renew, exchange, increase or alter, Senior Indebtedness, or otherwise amend, modify or supplement in
any manner Senior Indebtedness or any instrument evidencing the same or any agreement under which Senior Indebtedness or any security thereof or guarantee thereof is outstanding; (ii) sell, exchange, release, surrender, realize upon, enforce or
otherwise deal with any property pledged, mortgaged or otherwise securing Senior Indebtedness; (iii) release any Person liable in any manner for the collection of Senior Indebtedness; (iv) exercise or refrain from exercising any rights
against the Company and any other Person; (v) apply any and all sums received from time to time to the Senior Indebtedness; provided that if any Senior Indebtedness is amended to provide that it shall be subordinated to any other Senior
Indebtedness, such amended Senior Indebtedness shall no longer be considered Senior Indebtedness for purposes of this Article 8. 
 The provisions of this Article 8 shall continue to be effective or be reinstated as the case may be if at any time any payment of the Senior Indebtedness is rescinded or must otherwise be
returned by the holder thereof upon the insolvency, bankruptcy or reorganization of the Company or otherwise, all as though such payment had not been made. 
 SECTION 8.09 Notice to Trustee. The Company shall give prompt written notice to a Responsible Officer of the Trustee of any fact known to the Company which would prohibit the making of any payment
to or by the Trustee in respect of the Notes. Notwithstanding the provisions of this Article 8 or any other provision of this Indenture, the Trustee shall not be 
  

 58 








 
charged with knowledge of the existence of any facts which would prohibit the making of any payment to or distribution by the Trustee in respect of the Notes, unless and until a Responsible
Officer of the Trustee shall have received written notice thereof from the Company or a holder of Senior Indebtedness or from any trustee therefor; and, prior to the receipt of any such written notice, the Trustee, subject to the provisions of
Section 11.01, shall be entitled in all respects to assume that no such facts exist; provided, however, that if the Trustee shall not have received the notice provided for in this Section 8.09 at least two
Business Days prior to the date upon which by the terms hereof any money may become payable for any purpose, then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such money and
to apply the same to the purpose for which such money was received and shall not be affected by any notice to the contrary which may be received by it within two Business Days prior to such date. 
 Subject to the provisions of the Indenture, the Trustee shall be entitled to rely conclusively on the delivery to it of a written notice by
a Person representing himself to be a holder of Senior Indebtedness (or a trustee therefor) to establish that such notice has been given by a holder of Senior Indebtedness (or a trustee therefor). In the event that the Trustee determines in good
faith that further evidence is required with respect to the right of any Person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article 8 (although the Trustee is not obligated to make
such determination), the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in
such payment or distribution and any other facts pertinent to the rights of such Person under this Article 8, and if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to
the right of such Person to receive such payment. 
 SECTION 8.10 Reliance on Judicial Order or Certificate of Liquidating
Agent. Upon any payment or distribution of assets of the Company referred to in this Article 8, the Trustee, subject to the provisions of the Indenture, and the holders of the Notes shall be entitled to conclusively rely upon any
order or decree entered by any court of competent jurisdiction in which such insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution, winding up or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit of creditors, agent or other Person making such payment or distribution, delivered to the Trustee or to the holders of Notes, for the purpose of ascertaining the Persons
entitled to participate in such payment or distribution, the holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article 8. 
 SECTION 8.11 Trustee Not Fiduciary for Holders of Senior
Indebtedness. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and (subject to Section 8.09 hereof) shall not be liable to any such holders if it shall in good faith mistakenly pay over
or distribute to holders of Notes or to the Company or to any other Person cash, property or securities to which any holders of Senior Indebtedness shall be entitled by virtue of this Article 8 or otherwise. 
  

 59 








 SECTION 8.12 Rights of Trustee as Holder of Senior Indebtedness; Preservation of
Trustee’s Rights. The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article 8 with respect to any Senior Indebtedness which may at any time be held by it, to the same extent as any
other holder of Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. 
 Nothing in this Article 8 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 11.06. 
 SECTION 8.13 Article Applicable to Paying Agents. In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term
“Trustee” as used in this Article 8 shall in such case (unless the context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if
such Paying Agent were named in this Article 8 in addition to or in place of the Trustee; provided, however, that Section 8.12 shall not apply to the Company or any Affiliate of the Company if it or such
Affiliate acts as Paying Agent. 
 SECTION 8.14 No Senior Subordinated Indebtedness. The Company shall not, directly or
indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to any indebtedness that is subordinate or junior in right of payment to any Senior Indebtedness and
senior in right of payment to the Notes. 
 SECTION 8.15 Amendment of Subordination Provisions. Any Senior Indebtedness
will continue to be Senior Indebtedness and will be entitled to the benefits of the subordination provisions of this Article 8 irrespective of any amendment, modification or waiver of any of such subordination provisions. 
 ARTICLE 9 
 COVENANTS OF THE COMPANY 
 SECTION 9.01 Payment of Principal, Premium and Interest. The Company

location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office or the office or agency of the Trustee in the Borough of Manhattan, The City of New York. 
  

 60 








 The Company may also from time to time designate co-registrars, one or more other offices or
agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of
any such other office or agency. The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable. 
 The Company hereby initially designates the Trustee as the Paying Agent, Note Registrar, Custodian and Conversion Agent and the Corporate
Trust Office and the office or agency of the Trustee in the Borough of Manhattan each shall be considered as one such office or agency of the Company for each of the aforesaid purposes. 
 SECTION 9.03 Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever necessary to avoid or fill a vacancy in
the office of Trustee, will appoint, in the manner provided in Section 11.10, a Trustee, so that there shall at all times be a Trustee hereunder. 
 SECTION 9.04 Provisions as to Paying Agent. (a) If the Company shall appoint a Paying Agent other than the Trustee, the Company will cause such Paying Agent to execute and deliver to the Trustee an
instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 9.04:

absence of bad faith and intentional misconduct on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to
the Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or opinions that by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to
examine the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein);

notice to be sent to the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred, unless such Responsible Officer of the Trustee had actual knowledge of such event; 

(g) in the absence of written investment direction from the Company, all cash received by the Trustee shall be placed in a non-interest
bearing trust account, and in no event shall the Trustee be liable for the selection of investments or for investment losses incurred thereon or for losses incurred as a result of the liquidation of any such investment prior to its maturity date or
the failure of the party directing such investments prior to its maturity date or the failure of the party directing such investment to provide timely written investment direction, and the Trustee shall have no obligation to invest or reinvest any
amounts held hereunder in the absence of such written investment direction from the Company;

direction of any of the Noteholders pursuant to the provisions of this Indenture, unless such Noteholders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities that may be incurred
therein or thereby; 
 (e) the Trustee shall not be bound to make any investigation into the facts or matters stated in any
resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such
facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be

entitled to examine the books, records and premises of the Company at reasonable times, in a reasonable manner and upon reasonable advance notice, personally or by agent or attorney at the
expense of the Company and shall incur no liability of any kind by reason of such inquiry or investigation; 
 (f) the Trustee
may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, custodians, nominees or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any
agent, custodian, nominee or attorney appointed by it with due care hereunder; and

profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action other than any such loss or damage caused by the Trustee’s intentional misconduct or negligence. The Trustee shall not
be charged with knowledge of any Default or Event of Default, except (1) any Default or Event of Default of which a Responsible Officer shall have actual knowledge or (2) any Default or Event of Default of which written notice shall have

Event of Default occurring pursuant to Sections 5.01(a), 5.01(b), 5.01(i) or 5.01(j). 
 SECTION 11.03 No Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes
no responsibility for the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes

rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust), and the Company will pay or reimburse
the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably incurred or made and reasonably documented by the Trustee in accordance with any of the provisions of this Indenture in any capacity thereunder
(including the reasonable compensation and the expenses and disbursements of its agents and counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as shall have been caused by its gross negligence
or, intentional misconduct. The Company also covenants to indemnify the Trustee in any capacity under this Indenture and any other document or transaction entered into in connection herewith and to hold it harmless against, any and all loss, claim,

held or collected by the Trustee, except, subject to the effect of Section 5.05, funds held in trust herewith for the benefit of the holders of particular Notes. The Trustee’s right to receive payment of any amounts due under this
Section 11.06 shall not be subordinate to any other liability or Indebtedness of the Company (even though the Notes may be so subordinated). The obligations of the Company under this Section 11.06 shall survive the
satisfaction and discharge of this Indenture and the earlier resignation or removal or the Trustee. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The indemnification provided
in this Section 11.06 shall survive the termination or defeasance of this Indenture and the resignation or removal of the Trustee. The Trustee shall notify the Company promptly of any claim of which a Responsible Officer receives written
notice for which it may seek indemnity. 
 Without prejudice to any other rights available to the Trustee under applicable law,
when the Trustee and its agents and any authenticating agent incur expenses or render services after an Event of Default specified in clauses (i) or (j) of Section 5.01 occurs, the expenses and the compensation for the services
are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws. 
 SECTION 11.07
Officers’ Certificate as Evidence. Except as otherwise provided in Section 11.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or
established prior to taking or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence and intentional misconduct on the part of the Trustee, be deemed
to be conclusively proved and established by an Officers’ Certificate delivered to the Trustee, and such Officers’ Certificate, in the absence of negligence and intentional misconduct on the part of the Trustee, shall be full warrant to
the Trustee for any action taken or omitted by it under the provisions of this Indenture upon the faith thereof.

under the Trust Indenture Act, if the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either (a) eliminate such interest within 90 days or (b) resign, to the extent
and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture.

Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least $50,000,000. If such Person
publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and
with the effect hereinafter specified in this Article. 
 SECTION 11.10 Resignation or Removal of Trustee. (a) The
Trustee may at any time resign by giving written notice of such resignation to the Company and by mailing notice thereof to the Noteholders at their addresses as they shall appear on the Note Register. Upon receiving such notice of resignation, the
Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If
no successor trustee shall have been so appointed and have accepted appointment within 60 days after the mailing of such notice of resignation to the Noteholders, the resigning Trustee may, upon ten Business Days’ notice to the Company and
the Noteholders, petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor trustee, or any Noteholder who has been a bona fide holder of a Note or Notes for at least six months may, subject to
the provisions of Section 5.11, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and
prescribe, appoint a successor trustee. 
 (b) In case at any time any of the following shall occur: 
 (i) the Trustee shall fail to comply with Section 11.08 within a reasonable time after written request therefor
by the Company or by any Noteholder who has been a bona fide holder of a Note or Notes for at least six months, or

Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 
  

 69 








 then, in any such case, the Company may by a Board Resolution remove the Trustee and appoint
a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of
Section 5.11, any Noteholder who has been a bona fide holder of a Note or Notes for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 
 (c) The holders of a majority in aggregate principal amount of the Notes at the time outstanding, as determined in accordance with
Section 12.04, may at any time remove the Trustee and nominate a successor trustee that shall be deemed appointed as successor trustee unless within ten days after notice to the Company of such nomination the Company objects thereto, in
which case the Trustee so removed or any Noteholder, upon the terms and conditions and otherwise as in Section 11.10(a) provided, may petition, at the expense of the Company, any court of competent jurisdiction for an appointment of a
successor trustee. 
 (d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of
the provisions of this Section 11.10 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 11.11. 
 SECTION 11.11 Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 11.10 shall execute, acknowledge and deliver to the Company and to its predecessor
trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein; but, nevertheless, on the written request of the Company or of the successor trustee, the trustee ceasing to act
shall, upon payment of any amounts then due it pursuant to the provisions of Section 11.06, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. 

Upon the reasonable written request of any such successor trustee, the Company shall execute any and all instruments in writing for more
fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a senior claim to which the Notes are hereby made subordinate on all money or property held or
collected by such trustee as such, except for funds held in trust for the benefit of holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 11.06. 
 No successor trustee shall accept appointment as provided in this Section 11.11 unless at the time of such acceptance such
successor trustee shall be qualified under the provisions of Section 11.08 and be eligible under the provisions of Section 11.09. 
 Upon acceptance of appointment by a successor trustee as provided in this Section 11.11, each of the Company and the successor trustee, at the written direction and at the expense of the

  

 70 








 
Company, shall mail or cause to be mailed notice of the succession of such trustee hereunder to the Noteholders at their addresses as they shall appear on the Note Register. If the Company fails
to mail such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company. 
 SECTION 11.12 Succession by Merger, Etc. Any corporation or other entity into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other entity succeeding to all or substantially all of the corporate
trust business of the Trustee (including the administration of this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided
that in the case of any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee, such corporation or other entity shall be qualified under the provisions of Section 11.08 and
eligible under the provisions of Section 11.09. 
 In case at the time such successor to the Trustee shall succeed
to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by
such predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee may
authenticate such Notes either in the name of any predecessor trustee hereunder or in the name of the successor trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture
provided that the certificate of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee
shall apply only to its successor or successors by merger, conversion or consolidation. 
 SECTION 11.13 Limitation on Rights
of Trustee as Creditor. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Notes), after qualification under the Trust Indenture Act, the Trustee shall be subject to the provisions of the Trust
Indenture Act regarding the collection of the claims against the Company (or any such other obligor). 
 SECTION 11.14
Trustee’s Application for Instructions from the Company. Any application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that
affects the rights of the holders of the Notes under this Indenture) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such
action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such
application (which date shall not be less than three Business Days after the date any officer that the Company has indicated to the Trustee should receive such application actually receives such application, unless any such officer shall have
consented in writing to any earlier date), unless, prior to taking any such action (or the effective date in the case of any omission), the Trustee shall have received written instructions in accordance with this Indenture in response to such
application specifying the action to be taken or omitted.

 SECTION 12.01 Action
by Noteholders. Whenever in this Indenture it is provided that the holders of a specified percentage in aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent
or waiver or the taking of any other action), the fact that at the time of taking any such action, the holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor
executed by Noteholders in person or by agent or proxy appointed in writing, or (b) by the record of the Noteholders voting in favor thereof at any meeting of Noteholders, or (c) by a combination of such instrument or instruments and any
such record of such a meeting of Noteholders. Whenever the Company or the Trustee solicits the taking of any action by the holders of the Notes, the Company or the Trustee may, but shall not be required to, fix in advance of such solicitation, a
date as the record date for determining Noteholders entitled to take such action. The record date if one is selected shall be not more than fifteen days prior to the date of commencement of solicitation of such action. 
 SECTION 12.02 Proof of Execution by Noteholders. Subject to the provisions of Section 11.01 and
Section 11.02, proof of the execution of any instrument by a Noteholder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as
shall be satisfactory to the Trustee. The holding of Notes shall be proved by the Note Register or by a certificate of the Note Registrar. 
 SECTION 12.03 Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion Agent and any Note Registrar may deem the Person in whose name a
Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other
than the Company or any Note Registrar) for the purpose of receiving payment of or on account of the principal of, premium, if any, and (subject to Section 2.03) accrued and unpaid interest on such Note, for conversion of such Note and
for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Note Registrar shall be affected by any notice to the contrary. All such payments so made to any holder for the time being, or upon
its order, shall be valid and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for monies payable upon any such Note. Notwithstanding anything to the contrary in this Indenture or the Notes following an
Event of Default, any holder of a beneficial interest in a Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such holder’s
right to exchange such beneficial interest for a Note in certificated form in accordance with the provisions of this Indenture. 
 SECTION 12.04 Company-Owned Notes Disregarded. In determining whether the holders of the requisite aggregate principal amount of Notes have concurred in any direction, 
  

 72 








 
consent, waiver or other action under this Indenture, Notes that are owned by the Company or by any Person directly or indirectly controlling or controlled by or under direct or indirect common
control with the Company shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction,
consent, waiver or other action only Notes that a Responsible Officer actually knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this
Section 12.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company or a Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee,
the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to
Section 11.01, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such
determination. 
 SECTION 12.05 Revocation of Consents; Future Noteholders Bound. At any time prior to (but not after)
the evidencing to the Trustee, as provided in Section 12.01, of the taking of any action by the holders of the percentage in aggregate principal amount of the Notes specified in this Indenture in connection with such action, any holder
of a Note that is shown by the evidence to be included in the Notes the holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in
Section 12.02, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the holder of any Note shall be conclusive and binding upon such holder and upon all future holders and owners of such Note and
of any Notes issued in exchange or substitution therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon
registration of transfer thereof. 
 ARTICLE 13 
 SATISFACTION AND DISCHARGE 
 SECTION 13.01
Satisfaction and Discharge of the Indenture. When (i) the Company shall deliver to the Note Registrar for cancellation all Notes theretofore authenticated (other than any Notes that have been destroyed, lost or stolen and in lieu of or
in substitution for which other Notes shall have been authenticated and delivered) and not theretofore canceled, or (ii) all the Notes not theretofore canceled or delivered to the Trustee for cancellation shall have become due and payable
(whether at Stated Maturity for the payment of the principal amount thereof or on any Fundamental Change Purchase Date or upon conversion or otherwise) and the Company shall deposit with the Trustee, in trust, or deliver to the Holders, as
applicable, cash funds and/or (in the case of conversion) shares of Common Stock (subject to our right to pay cash in lieu thereof), as applicable, sufficient to pay all amounts due or deliverable on all of such Notes (other than any Notes that
shall have been mutilated, destroyed, lost or stolen and in lieu of or in substitution for which other Notes shall have been authenticated and delivered) not theretofore canceled or delivered to the Trustee for cancellation, including principal and
interest due, 
  

 73 








 
accompanied, except in the event the Notes are due and payable solely in cash at the Stated Maturity of the Notes or upon an earlier Fundamental Change Purchase Date, by a verification report as
to the sufficiency of the deposited amount from an independent certified accountant or other financial professional reasonably satisfactory to the Trustee (which may include any of the Underwriters), and if the Company shall also pay or cause to be
paid all other sums payable hereunder by the Company, then this Indenture shall cease to be of further effect (except as to (A) rights hereunder of Holders of the Notes to receive all amounts owing upon the Notes and the other rights, duties
and obligations of Holders of the Notes, as beneficiaries hereof with respect to the amounts, if any, so deposited with the Trustee and (B) the rights, obligations and immunities of the Trustee hereunder), and the Trustee, on written demand of
the Company accompanied by an Officers’ Certificate and an Opinion of Counsel and at the cost and expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture; the Company, however, hereby
agrees to reimburse the Trustee for any costs or expenses thereafter reasonably and properly incurred by the Trustee, including the fees and expenses of its counsel, and to compensate the Trustee for any services thereafter reasonably and properly
rendered by the Trustee in connection with this Indenture or the Notes. 
 SECTION 13.02 Deposit of Monies to be Held in
Trust by Trustee. Subject to Section 13.04, all monies deposited with the Trustee pursuant to Section 13.01 shall be held in trust for the sole benefit of the Holders of the Notes, and such monies shall be applied by the
Trustee to the payment, either directly or through any Paying Agent (including the Company if acting as its own Paying Agent), to the Holders of the particular Notes for the payment or redemption of which such monies have been deposited with the
Trustee, of all sums due and to become due thereon for principal and interest, if any. 
 SECTION 13.03 Paying Agent to Repay
Monies Held. Upon the satisfaction and discharge of this Indenture, all monies then held by any Paying Agent (if other than the Trustee) shall, upon written request of the Company, be repaid to it or paid to the Trustee, and thereupon such
Paying Agent shall be released from all further liability with respect to such monies. 
 SECTION 13.04 Return of Unclaimed
Monies. Subject to the requirements of applicable law, any monies deposited with or paid to the Trustee for payment of the principal of or interest, if any, on the Notes and not applied but remaining unclaimed by the Holders of the Notes for two
years after the date upon which the principal of or interest, if any, on such Notes, as the case may be, shall have become due and payable, shall be repaid to the Company by the Trustee on demand, and all liability of the Trustee shall thereupon
cease with respect to such monies; and the Holder of any of the Notes shall thereafter look only to the Company for any payment that such Holder of the Notes may be entitled to collect unless an applicable abandoned property law designates another
Person. 
 SECTION 13.05 Reinstatement. If the Trustee or the Paying Agent is unable to apply any money in accordance
with Section 13.02 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under the Indenture and the Notes shall be
revived and reinstated as though no deposit had occurred pursuant to Section 13.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money in accordance with Section 13.02; provided,
however, that if the Company makes any payment of interest on or principal of any Note

  

 74 








 
following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying
Agent. 
 ARTICLE 14 
 MISCELLANEOUS 
 SECTION 14.01 Provisions Binding on Company’s
Successors. All the covenants, stipulations, promises and agreements of the Company contained in this Indenture shall bind its successors and assigns whether so expressed or not. 
 SECTION 14.02 Official Acts by Successor Corporation. Any act or proceeding by any provision of this Indenture authorized or required
to be done or performed by any board, committee or officer of the Company shall and may be done and performed with like force and effect by the like board, committee or officer of any corporation or other entity that shall at the time be the lawful
successor of the Company. 
 SECTION 14.03 Addresses for Notices, Etc. Any notice or demand that by any provision of this
Indenture is required or permitted to be given or served by the Trustee or by the Noteholders on the Company shall be deemed to have been sufficiently given or made, for all purposes if given or served by being deposited postage prepaid by

Treasurer with a copy to Kirkland & Ellis LLP, 300 North LaSalle Street, Chicago, IL 60654, Attention: Dennis Myers. Any notice, direction, request or demand hereunder to or upon the Trustee shall be deemed to have been sufficiently given
or made, for all purposes, if given or served by a facsimile transmission or by being deposited postage prepaid by registered or certified mail in a post office letter box addressed to the Corporate Trust Office. 
 The Trustee, by notice to the Company, may designate additional or different addresses for subsequent notices or communications. 

The Trustee agrees to accept and act upon instructions or directions pursuant to this Indenture sent by unsecured e-mail, facsimile

directions to the Trustee in a timely manner, and (b) such originally executed instructions or directions shall be signed by an authorized representative of the party providing such instructions or directions. If the party elects to give the Trustee

shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such instructions notwithstanding such instructions conflict or are inconsistent with a subsequent written
instruction. The party providing electronic instructions agrees to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Trustee, including without limitation the risk of the Trustee acting
on unauthorized instructions, and the risk or interception and misuse by third parties. 
 Any notice or communication mailed to
a Noteholder shall be mailed to it by first class mail, postage prepaid, at its address as it appears on the Note Register and shall be sufficiently given to it if so mailed within the time prescribed. 
 Failure to mail a notice or communication to a Noteholder or any defect in it shall not affect its sufficiency with respect to other
Noteholders. If a notice or communication is mailed in the manner provided above, it is duly given, whether or not the addressee receives it. 
 In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice to holders by mail, then such notification as shall be made with
the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. 
 Notwithstanding any other
provision of this Indenture or any Note, whenever notice is required to be given to a holder of a Global Note, such notice shall be sufficiently given if given to the Depositary for such Note (or its designee), pursuant to customary procedures of
such Depositary.

 (i) an Officers’ Certificate stating that, in the opinion of the signers, all conditions precedent, if any, provided for
in this Indenture relating to the proposed action have been complied with; and 
 (ii) an Opinion of Counsel
stating that, in the opinion of such counsel, all such conditions precedent have been complied with. 
 (b) Each certificate or
opinion with respect to compliance with a condition or covenant provided for in this Indenture shall include: 
 (i) a statement that each person signing such certificate or opinion has read such covenant or condition and the definitions herein relating thereto; 
 (ii) a brief statement as to the nature and scope of the examination or investigation upon which the statement or opinion
contained in such certificate or opinion is based;

the person has made such examination or investigation as is necessary to enable the person to express an informed opinion as to whether or not such covenant or condition has been complied with; and 
 (iv) a statement as to whether or not, in the opinion of each such person, such condition or covenant has been complied with;
provided, however, that, with respect to matters of fact, an Opinion of Counsel may rely on an Officers’ Certificate or certificates of public officials. 
 SECTION 14.06 Payments on Business Days. If any Interest Payment Date or the Stated Maturity of the Notes or any earlier required
repurchase date would fall on a day that is not a Business Day, the required payment shall be made on the next succeeding Business Day and no interest on such payment shall accrue in respect of the delay.

constitute a security interest under the Uniform Commercial Code or similar legislation, as now or hereafter enacted and in effect, in any jurisdiction. 
  

 76 








 SECTION 14.08 Trust Indenture Act. This Indenture is hereby made subject to, and
shall be governed by, the provisions of the Trust Indenture Act required to be part of and to govern indentures qualified under the Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with another provision hereof that is
required to be included in an indenture qualified under the Trust Indenture Act, such required provision shall control. 
 SECTION 14.09 Benefits of Indenture. Nothing in this Indenture or in the Notes, expressed or implied, shall give to any Person, other than the parties hereto, any Paying Agent, any Conversion Agent, any Bid Solicitation Agent, any
authenticating agent, any Note Registrar and their successors hereunder or the Holders of the Notes, any benefit or any legal or equitable right, remedy or claim under this Indenture. 
 SECTION 14.10 Authenticating Agent. The Trustee may appoint an authenticating agent that shall be authorized to act on its behalf and
subject to its direction in the authentication and delivery of Notes in connection with the original issuance thereof and transfers and exchanges of Notes hereunder, including under Section 2.05, Section 2.06,
Section 2.07, Section 2.08, Section 3.04 and Section 7.04 as fully to all intents and purposes as though the authenticating agent had been expressly authorized by this Indenture and those Sections to
authenticate and deliver Notes. For all purposes of this Indenture, the authentication and delivery of Notes by the authenticating agent shall be deemed to be authentication and delivery of such Notes “by the Trustee” and a certificate of
authentication executed on behalf of the Trustee by an authenticating agent shall be deemed to satisfy any requirement hereunder or in the Notes for the Trustee’s certificate of authentication. Such authenticating agent shall at all times be a
Person eligible to serve as trustee hereunder pursuant to Section 11.09. 
 Any corporation or other entity into
which any authenticating agent may be merged or converted or with which it may be consolidated, or any corporation or other entity resulting from any merger, consolidation or conversion to which any authenticating agent shall be a party, or any
corporation or other entity succeeding to all or substantially all the corporate trust business of any authenticating agent, shall be the successor of the authenticating agent hereunder, if such successor corporation or other entity is otherwise
eligible under this Section, without the execution or filing of any paper or any further act on the part of the parties hereto or the authenticating agent or such successor corporation or other entity. 
 Any authenticating agent may at any time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may
at any time terminate the agency of any authenticating agent by giving written notice of termination to such authenticating agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time any
authenticating agent shall cease to be eligible under this Section, the Trustee may appoint a successor authenticating agent (which may be the Trustee), shall give written notice of such appointment to the Company and shall mail notice of such
appointment to all Noteholders as the names and addresses of such holders appear on the Note Register. 
 The Company agrees to
pay to the authenticating agent from time to time reasonable compensation for its services although the Company may terminate the authenticating agent, if it determines such agent’s fees to be unreasonable. 
  

 77 








 The provisions of Section 11.02, Section 11.03,
Section 11.04, Section 12.03 and this Section 14.10 shall be applicable to any authenticating agent.

authentication in the following form:

restrict any of the terms or provisions hereof.

executed in any number of counterparts, each of which shall be an original, but such counterparts shall together constitute but one and the same instrument.

enforceability of the remaining provisions shall not in any way be affected or impaired.

Others. No director, officer, employee, stockholder, incorporator or agent of the Company will have any liability for any obligations of the Company under the Notes, the Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such liability.

IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTION CONTEMPLATED HEREBY. 
 SECTION 14.18 Force Majeure. In no event shall the Trustee be responsible or liable for any failure or delay in the performance of

practices in the banking industry to resume performance as soon as practicable under the circumstances.

Navistar International Corporation, a Delaware corporation (herein called the “Company”, which term includes any
successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay CEDE & CO., or registered assigns, [            ] DOLLARS
($[            ]) (or such greater or lesser principal amount as shall be specified in the “Schedule of Exchanges of Securities” attached hereto) on October 15, 2014 unless
earlier converted or repurchased, and to pay interest thereon as set forth in the manner, at the rates and to the Persons set forth in the Indenture. 
 This Note shall bear interest at a rate of [    ] % per annum from
[                    ], 2009 or from the most recent date to which interest had been paid or provided to, but excluding, the next scheduled Interest
Payment Date, until the principal hereof shall be repaid. Interest on this Note will be computed on the basis of a 360-day year composed of twelve 30-day months. Interest is payable semi-annually in arrears on each April 15 and October 15,
commencing on April 15, 2010, to the Person in whose name this Note (or one or more predecessor securities) is registered at the close of business on the Regular Record Date for such interest. Additional Interest will be payable at the option
of the Company on the terms set forth in Section 5.02 of the within-mentioned Indenture. 
 The Company will pay

Holders on a special record date, which will be the 15th day preceding the date fixed by the Company for the payment of such interest, whether or not such day is a Business Day. At least 15 days before a special record date, the Company will
send to each Holder and to the Trustee a notice that sets forth the special record date, the payment date and the amount of interest to be paid. 
 The Company shall pay principal of and interest on this Note, so long as such Note is a Global Note, in immediately available funds to the Depositary or its nominee, as the case may be, as the registered
Holder of such Note. The Company shall pay principal of any Notes (other than Notes that are Global Notes) at the office or agency designated by the Company for that purpose. The Company has initially designated the Trustee as its Paying Agent and
Note Registrar in respect of the Notes and its agency in New York, New York as a place where Notes may be presented for payment or for registration of transfer. The Company may, however, change the Paying Agent or Note Registrar for the Notes
without prior notice to the Holders thereof, and the Company may act as Paying Agent or Note Registrar. Interest on the Notes (other than Notes that are Global Notes) will be payable (i) to Holders of the Notes having an aggregate principal
amount of Notes of $5,000,000 or less, by check mailed to the Holders of these Notes at their address in the Note Register and (ii) to Holders having an aggregate principal amount of Notes in excess of $5,000,000, either by check mailed to each
Holder at its address in

 Reference is hereby made to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

 In the case of any conflict between this Note and the Indenture, the provisions of the Indenture shall control. This Note,
for all purposes, shall be governed by and construed in accordance with the laws of the State of New York.
