 Section 1.04 Acts of Holders. Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in
writing; and, except as herein otherwise expressly provided, such action will become effective when such instrument or instruments are delivered to the Trustee and to the Company. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the “Act” of Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent will be sufficient for any
purpose of this Indenture and conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section 1.04. 

The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to such officer the execution thereof. Where such
execution is by a signer acting in a capacity other than such signer’s individual capacity, such certificate or affidavit will also constitute sufficient proof of such signer’s authority. The fact and date of the execution of any such

entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company will have no obligation to do so. If such a record date is fixed, such request, demand,


  
 - 14 - 








 
authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the Close of Business on such record date will be
deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of outstanding Notes have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act,
and, for that purpose, the outstanding Notes will be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date will be deemed effective unless it will become effective
pursuant to the provisions of this Indenture not later than six months after the record date. 
 ARTICLE 2 

THE NOTES

issued, authenticated and delivered on the Issue Date under this Indenture is $105,000,000. From time to time, the Company may issue and execute, and the Trustee may authenticate, Notes delivered upon registration of transfer of, or in exchange for,
or in lieu of, other Notes pursuant to Sections 2.09, 2.11, 2.12, 3.06 and 10.02 hereof. In addition, the Company may issue an unlimited aggregate principal amount of additional Notes in accordance with clause (b) of this Section 2.01.

 (b) Without the consent of any Holder, and notwithstanding anything to the contrary in Sections 2.01(a) or 2.05 hereof, the
Company may increase the aggregate principal amount of the Notes issued under this Indenture by reopening this Indenture and issuing additional Notes with the same terms as the initial Notes (except, to the extent applicable, with respect to the
issue price, the date as of which interest shall begin to accrue on such additional Notes and as to the Last Original Issue Date with respect to such additional Notes as provided in the proviso to the definition thereof), which Notes will, subject
to the foregoing, be considered to be part of the same series of Notes as those initially issued hereunder; provided, however, that if any such additional Notes are not fungible with other Notes issued hereunder for federal income tax
purposes, then such additional Notes shall have a separate CUSIP number. Prior to issuing any such additional Notes, the Company will deliver to the Trustee a Company Order, an Officers’ Certificate and an Opinion of Counsel, which
Officers’ Certificate and Opinion of Counsel will address any matters required to be addressed under Section 12.04 hereof. 

Section 2.02 Form of Notes. 

(a) General. The Notes will be substantially in the form of Exhibit A hereto, but may include any notations, legends or
endorsements required by any applicable law (or regulation promulgated thereunder), stock exchange rule or usage, or any insertions, omissions or other variations otherwise permitted or required by this Indenture. Whenever any such notation, legend

 - 15 -

Decreases of Global Note” attached thereto. 
 Notes that are Restricted Notes will bear the Restricted Notes Legend. 

The terms and provisions contained in the Notes will constitute, and are hereby expressly made, a part of this Indenture and, to the extent
applicable, the Company and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent that any provision of any Note conflicts with the express
provisions of this Indenture, the provisions of this Indenture will govern and control. 
 (b) Initial and Subsequent Notes.
The Notes initially will be issued in global form, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee, as custodian for the Depositary. Except to the extent provided in
Section 2.09(c) hereof, all Notes will be represented by one or more Global Notes. 
 (c) Global Notes. Each
Global Note will represent the aggregate principal amount of then outstanding Notes endorsed thereon and provide that it represents such aggregate principal amount of then outstanding Notes, which aggregate principal amount may, from time to time,
be reduced or increased to reflect transfers, exchanges, conversions, redemptions or repurchases by the Company. 
 Only the Trustee,
or the custodian holding such Global Note for the Depositary, at the direction of the Trustee, may endorse a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of then outstanding Notes represented
thereby, and whenever the Holder of a Global Note delivers instructions to the Trustee to increase or decrease the aggregate principal amount of then outstanding Notes represented by a Global Note in accordance with Section 2.09 hereof, the
Trustee, or the custodian holding such Global Note for the Depositary, at the direction of the Trustee, will endorse such Global Note to reflect such increase or decrease in the aggregate principal amount of then outstanding Notes represented
thereby. None of the Trustee, the Company or any agent of the Trustee or the Company will have any responsibility or bear any liability for any aspect of the records relating to, or payments made on account of, the ownership of any beneficial
interest in a Global Note or with respect to maintaining, supervising or reviewing any records relating to such beneficial interest. 

Neither any member of, or participant in, the Depositary (collectively, the “Agent Members”) nor any other Person on
whose behalf an Agent Member may act will have any rights under this Indenture with respect to any Global Note or under such Global Note, and the Company, the Trustee and any agent of the Company or the Trustee, may, for all purposes, treat the
Depositary, or its nominee, if any, as the absolute owner and Holder of such Global Note. 
 The Holder of a Global Note may grant
proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action that such Holder is entitled to take under this Indenture or the Notes with respect to such Global
Note, and, notwithstanding the foregoing, nothing herein will prevent the Company, 

  
 - 16 - 








 
the Trustee, the Paying Agent or any agent of the Company, the Trustee or the Paying Agent from giving effect to any written certification, proxy or other authorization furnished by such Holder
or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act, the operation of their respective customary practices governing the exercise of the rights of a Holder of any interest in any
Global Note. 
 Section 2.03 Denomination of Notes. The Notes will be issuable in registered form without coupons in minimum
denominations of $1,000 principal amount and in integral multiples of $1,000 in excess thereof. 
 Section 2.04 Payments. 

(a) General. 
 (i)
Payment at Maturity. Unless earlier paid or deemed paid pursuant to any of Sections 3.05, 10.03 or 11.06 hereof, the Notes will mature on October 1, 2019 (the “Maturity Date”) and, on the Maturity Date, the
Company will pay each Holder of Notes $1,000 in cash for each $1,000 principal amount of Notes held, together with accrued and unpaid interest to, but not including, the Maturity Date on such Notes. 

(ii) Payment of Interest. Each Note will accrue interest at a rate equal to 4.25% per annum from the most recent date to
which interest has been paid or duly provided for, or, if no interest has been paid or duly provided for, the Issue Date (or such other date provided for in Section 2.01(b) with respect to Notes issued in accordance with such Section) until,
subject to the provisions of clause (d) of this Section 2.04, the date the principal amount of such Note is paid or deemed paid, as the case may be, pursuant to clause (i) of this Section 2.04(a) or any of Sections 3.05, 10.03 or
11.06 hereof. 
 Interest will be payable semi-annually in arrears on April 1 and October 1 of each year (each, an
“Interest Payment Date”), beginning April 1, 2015, to the Holder of each such Note as of the Close of Business on the March 15 and September 15, as the case may be, and whether or not on a Business Day, immediately
preceding the applicable Interest Payment Date (each such date, a “Regular Record Date”), regardless of whether such Note is converted, repurchased or redeemed after such Regular Record Date. Interest will be computed on the basis
of a 360-day year comprised of twelve 30-day months and, for partial months, on the basis of the number of days actually elapsed in a 30-day month. 

(iii) Method of Payment. The Company will pay, or cause the Paying Agent to pay, the principal of, the Fundamental Change
Repurchase Price or the Redemption Price for, and the interest on, any Global Note to the Depositary by wire transfer of immediately available funds on the relevant payment date. 

The Company will pay, or cause the Paying Agent to pay, the principal of, the Fundamental Change Repurchase Price or Redemption Price for, and
any interest due on the Maturity Date on, any Definitive Note in cash to the applicable Holder of such Note at the office of the Paying Agent on the relevant payment date. 

  
 - 17 - 








 The Company will pay, or cause the Paying Agent to pay, interest due, on an Interest Payment
Date, on any Definitive Note (except interest due on the Maturity Date) to the applicable Holder of such Note (i) if such Holder holds $5,000,000 or less aggregate principal amount of Notes, by check mailed to such Holder’s registered
address, and (ii) if such Holder holds more than $5,000,000 aggregate principal amount of Notes, (A) by check mailed to such Holder’s registered address or (B) if such Holder delivers, not later than the Regular Record Date
relating to such Interest Payment Date, a written request to the Registrar that the Company make such payments by wire transfer to an account of such Holder within the United States, by wire transfer of immediately available funds to such account,
which request shall remain in effect until such Holder notifies, in writing, the Registrar to the contrary. 
 (b) Interest Rights
Preserved. Subject to the provisions of Section 2.04(d) hereof, and, to the extent applicable, Sections 2.09 and 2.11 hereof, each Note delivered under this Indenture upon registration of transfer of, or in exchange for, or in lieu of, any
other Note will carry any rights to the payment and accrual of interest that were carried by the relevant surrendered Note, Notes, or portion(s) thereof. 

(c) Additional Interest; Extension Fee. Pursuant to Section 4.04 hereof, in certain circumstances, Additional Interest will
accrue on the Notes. Pursuant to Section 6.04 hereof, in certain circumstances, the Company may, at its election, be obligated to pay Holders the Extension Fee. Unless the context requires otherwise, all references in this Indenture to interest
on the Notes will include such Additional Interest and Extension Fee, but will not include any Default Interest payable pursuant to Section 2.04(d) hereof. 

(d) Defaulted Amounts. Whenever any amount payable on a Note (including, the principal of, the Fundamental Change Repurchase
Price or Redemption Price for, and interest on, such Note) has become due and payable, but the Company fails to punctually pay or duly provide for such amount (any such amount, a “Defaulted Amount”), such Defaulted
Amount will forthwith cease to be payable to the Holder of such Note on the relevant payment date by virtue of its having been due such payment on such payment date, but will instead, to the extent permitted under applicable law, accrue interest
(“Default Interest”) at a rate equal to 4.25% per annum from, and including, such payment date and to, but excluding, the date on which such Defaulted Amount is paid by the Company in accordance with either clause
(i) or (ii) below. 
 (i) The Company may elect to pay any Defaulted Amount and Default Interest on such Defaulted Amount
to the Persons in whose names the Notes (or their respective predecessor Notes) are registered at the Close of Business on a special record date for the payment of such Defaulted Amount and Default Interest (a “Special Regular Record
Date”) fixed in accordance with the following procedures: 
 (A) At least 25 days (or such lesser period as
to which the Trustee may agree) before the date on which the Company proposes to pay such Defaulted Amounts and Default Interest thereon, the Company will deliver to the Trustee written notice of (I) the proposed payment date for such Defaulted
Amounts and Default Interest thereon and (II) the aggregate amount of such Defaulted Amounts and Default Interest thereon. 

  
 - 18 - 








 (B) Simultaneously with delivering such notice to the Trustee, the Company will
either (I) deposit with the Trustee an amount of money, in immediately available funds, equal to the aggregate amount of such Defaulted Amounts and Default Interest thereon, or (II) take other actions that the Trustee deems satisfactory to
ensure that an amount of money, in immediately available funds, equal to the aggregate of such Defaulted Amounts and Default Interest thereon will be deposited with the Trustee by 11:00 a.m., New York City time, on or prior to the proposed payment
date, and in either case, upon receipt of such money, the Trustee will hold such money in trust for the benefit of the Persons entitled to such Defaulted Amounts and Default Interest pursuant to this Section 2.04(d)(i). 

(C) Upon (i) receipt of such notice and (ii) the Company’s depositing such money or taking such other actions
reasonably satisfactory to the Trustee, the Company will promptly fix a Special Regular Record Date for the payment of such Defaulted Amounts and Default Interest thereon, which Special Regular Record Date will be not more than 15 calendar days and
not less than 10 calendar days prior to the proposed payment date, and notify the Trustee of the Special Regular Record Date. The Trustee will then, in the name and at the expense of the Company, deliver notice to each Holder specifying such Special
Regular Record Date and the date on which such Defaulted Amounts and Default Interest thereon will be paid by the Company. 

(D) After such notice has been delivered by the Trustee, such Defaulted Amounts and Default Interest thereon will be paid to
the Persons in whose names the Notes (or their respective predecessor Notes) are registered at the Close of Business on the Special Regular Record Date specified in such notice and such Defaulted Amounts and Default Interest thereon will no longer
be payable pursuant to the following clause (ii) of this Section 2.04(d)(i). 
 (ii) The Company may pay any Defaulted Amounts and
Default Interest on such Defaulted Amounts in any other lawful manner that is not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes are then listed (or, if applicable, have been approved
for listing) or designated for issuance, and upon such notice as may be required by such exchange or automated quotation system, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of
payment will be deemed practicable by the Trustee. 
 Section 2.05 Execution and Authentication. 

(a) In General. A Note will be valid only if executed by the Company and authenticated by the Trustee. 

(b) Execution. A Note will be deemed to have been executed by the Company when an Officer signs such Note on behalf of the
Company. The Officer’s signature may be manual or facsimile (including .pdf), and the validity of such Officer’s signature will not turn on whether such signatory remains an Officer at the time the Trustee authenticates such Note.


  
 - 19 - 








 (c) Authentication. A Note will be deemed authenticated when an authorized
signatory of the Trustee manually signs the certificate of authentication on such Note. An authorized signatory of the Trustee will manually sign the certificate of authentication on a Note only if (i) the Company delivers such Note to the
Trustee, (ii) such Note is validly executed by the Company in accordance with Section 2.05(b) hereof, and (iii) the Company delivers, before or with such Note, a Company Order setting forth (A) a request that the Trustee
authenticate such Note; (B) the principal amount of such Note; (C) the name of the Holder of such Note, (D) the date on which such Note is to be authenticated; and (E) any insertions, omissions or other variations, notations,
legends or endorsements permitted under Section 2.02 hereof and applicable to such Note. If the Company Order also specifies that the Trustee must deliver such Note to the Holder or the Depositary, the Trustee will promptly deliver such Note in
accordance with such Company Order. 
 The Trustee may appoint an authenticating agent. If the Trustee appoints an authenticating
agent and such authenticating agent is reasonably acceptable to the Company, such authenticating agent may authenticate a Note whenever the Trustee may authenticate such Note. For purposes of this provision, each reference in this Indenture to
authentication by the Trustee will be deemed to include authentication by an authenticating agent, and an authenticating agent will have the same rights to deal with the Company as the Trustee would have if it were performing the duties that the
authentication agent was validly appointed to undertake. 
 Section 2.06 Registrar, Paying Agent and Conversion Agent. 

(a) General. The Company will maintain an office or agency in the continental United States where Notes may be
presented for registration of transfer or for exchange (the “Registrar”), an office or agency where the Notes may be presented for payment, repurchase or redemption (the “Paying Agent”), an office or agency where
the Notes may be presented for conversion (the “Conversion Agent”) and an office or agency where notices and demands to, or upon, the Company with respect to the Notes and this Indenture may be served. 

The Registrar will keep a register for the recordation of, and will record, the names and addresses of Holders, the Notes held by each
Holder and the transfer, exchange, repurchase, redemption and conversion of Notes (the “Register”). Absent manifest error, the entries in the Register will be conclusive and the parties may treat each Person whose name is recorded
in the Register pursuant to the terms hereof as a Holder hereunder for all purposes of this Indenture. The Register will be in written form or in any form capable of being converted into written form within a reasonably prompt period of time.

 The Company may have one or more registrars, one or more paying agents, one or more conversion agents and one or more places where
notices and demands to, or upon, the Company with respect to the Notes and this Indenture may be served. Before appointing any Registrar, Paying Agent or Conversion Agent that is not otherwise a party to this agreement, the Company will enter into
an appropriate agency agreement with such Registrar, Paying Agent or Conversion Agent, as the case may be, which agency agreement will implement the provisions of this Indenture that relate to such replacement or additional registrar, paying agent
or conversion agent, as the case may be. The term Registrar includes any additional registrars named pursuant 

  
 - 20 - 








 
to this Indenture. The term Paying Agent includes any additional paying agent named pursuant to this Indenture. The term Conversion Agent includes any additional conversion agent named pursuant
to this Indenture. Upon the occurrence of any Event of Default under Section 6.01(a)(ix) or 6.01(a)(x) with respect to the Company, the Trustee shall be the Paying Agent. 

(b) Initial Designations. The Company initially appoints the Trustee as each of the Registrar, the Paying Agent, Conversion
Agent, and the Notes initially may be presented for registration of transfer or for exchange, payment, repurchase, redemption and conversion to the Trustee, in its capacity as the Registrar, Paying Agent or Conversion Agent, as the case may be, at
the Corporate Trust Office. Notices and demands to, or upon, the Company with respect to the Notes and this Indenture may be served at the office of the Company identified in Section 12.02.  

(c) Removal, Resignation and Replacement. The Company may remove any Registrar, Paying Agent or Conversion Agent by delivering
written notice to the Trustee and to such Registrar, Paying Agent or Conversion Agent; provided, however, that no such removal will become effective unless (i) after such removal, at least one Registrar, Paying Agent and
Conversion Agent will remain; (ii) a successor has accepted appointment as Registrar, Paying Agent or Conversion Agent, as the case may be, the Company and such successor have entered into an agency agreement in accordance with
Section 2.06(a) hereof, and the Company has delivered written notice of such appointment and a copy of such agency agreement to the Trustee, or (iii) the Company has delivered written notice to the Trustee that the Trustee will serve as
the successor Registrar, Paying Agent or Conversion Agent, as the case may be, in accordance with Section 2.06(d) hereof; and provided, further, that the right to effect any such change or removal in no way relieves the Company of
its obligation to maintain a Registrar, Paying Agent and Conversion Agent in the continental United States. The Company may also change the place where notices and demands to, or upon, the Company with respect to the Notes and this Indenture may be
served, or reduce the number of such places; provided, however, that the right to effect any such change or reduction in no way relieves the Company of its obligation to maintain a place in the continental United States where notices
and demands to, or upon, the Company with respect to the Notes and this Indenture may be served. 
 In addition, the
Registrar, Paying Agent or Conversion Agent may resign at any time by delivering written notice of such resignation to each of the Company and the Trustee; provided, however, that if the Trustee is serving as Registrar, Paying Agent or
Conversion Agent, the Trustee may resign from such capacity only if it also resigns as Trustee in accordance with Section 7.07 hereof. If, after any such resignation, at least one Registrar, Paying Agent and Conversion Agent does not remain,
the Trustee will immediately be deemed to serve such empty office or agency in accordance with Section 2.06(d) hereof. 

(d) Failure to Maintain an Office or Agency. If the Company fails to maintain in the continental United States, a Registrar,
Paying Agent, Conversion Agent or place where notices and demands to, or upon, the Company with respect to the Notes and this Indenture may be served, the Trustee will act as the Registrar, Paying Agent, Conversion Agent, or place, as the case may
be, and the office where the Notes may be presented for registration of transfer or for exchange, presented for payment, repurchase or redemption or surrendered for conversion will be the Corporate Trust Office. In each such case, the Trustee will
be entitled to compensation for such action pursuant to Section 7.06 hereof. 

  
 - 21 - 








 (e) Notices. Promptly upon the effectiveness of any removal or appointment of a
Registrar, Paying Agent or Conversion Agent, or upon any change in the location of the office of any Registrar, Paying Agent or Conversion Agent, or of the place where notices and demands to, or upon, the Company with respect to the Notes and this
Indenture may be served, the Company will deliver to each Holder notice of such removal, appointment or change in location, as the case may be, which notice will include a brief description of the removal, appointment or change in location, as the
case may be, and list the name and address of each continuing (and newly appointed, if applicable) Registrar, Paying Agent and Conversion Agent and place where notices and demands to, or upon, the Company with respect to the Notes and this Indenture
may be served. 
 Section 2.07 Money and Securities Held in Trust. 

Except as otherwise provided herein, by no later than 11:00 a.m., New York City time, on each due date for a payment on any Note, the Company
will deposit with the Paying Agent an amount of money in immediately available funds, if deposited on the due date sufficient to make such payment when due. 

The Company will require that each Paying Agent (other than the Trustee, if the Trustee is a Paying Agent) agree in writing that it will
(i) segregate all money and securities it holds for making payments with respect to the Notes; (ii) hold such money and securities in trust for the benefit of Holders; and (iii) notify the Trustee, in writing, as promptly as
practicable, if the Company defaults in making any payment on the Notes. 
 If any such default has occurred and is continuing, the Paying
Agent will, upon receiving a written request from the Trustee, promptly pay to the Trustee all of the money and securities it holds in trust. In addition, at any time, the Company may require a Paying Agent to pay all money and securities that it
holds for making payments with respect to the Notes to the Trustee and to account for any money and securities it has disbursed. After delivering all of such money and securities to the Trustee pursuant to this Section 2.07, the Paying Agent
(in its capacity as such) will have no further liability for such money and securities. 
 Section 2.08 Holder Lists. 

The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of
Holders. If the Trustee is not the Registrar, the Company will furnish to the Trustee, (i) within five Business Days after each Regular Record Date, a list of the names and addresses of Holders as of such Regular Record Date, and (ii) at
such other times as the Trustee may request in writing, within 30 days after receipt by the Company of such request, a list of the names and addresses of Holders as of no more than 15 days immediately prior to the date such list is furnished, in
each case, in such form as the Trustee may reasonably require.

beneficial interests in Global Notes may be transferred or exchanged from time to time as desired, and each such transfer or exchange will be noted by the Registrar in the Register. 

(ii) All Notes issued upon any registration of transfer or exchange in accordance with this Indenture will be the valid obligations of the
Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or exchange.

in connection with such registration of transfer or exchange. 
 (iv) Unless the Company specifies otherwise, none of the Company, the

(ii) subject to a Fundamental Change Repurchase Notice validly delivered pursuant to Section 3.03 hereof, except to the extent any portion of such Note is not subject to a Fundamental Change Repurchase Notice or the Company fails to pay
the applicable Fundamental Change Repurchase Price when due, or (iii) after the Company has delivered a Redemption Notice pursuant to Section 11.03 hereof, except to the extent the Company fails to pay the applicable Redemption Price when
due. 
 (v) Nothwithstanding anything to the contrary herein, the Trustee will have no obligation or duty to monitor, determine or inquire
as to compliance with any restrictions on Transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depositary participants or beneficial owners
of interests in any Global Note) other than to require delivery of such transfer certificates (in the form attached hereto as Exhibit B) as are expressly required by, and to do so if and when expressly required by the terms of this Indenture, and to

(i) Notwithstanding any other provision of this Indenture, each Global Note will be exchanged for Definitive Notes if the Depositary delivers
written notice to the Company that: 
 (I) the Depositary is unwilling or unable to continue to act as Depositary; or 

(II) the Depositary is no longer registered as a clearing agency under the Exchange Act, 

and, in each case, the Company promptly delivers a copy of such notice to the Trustee and the Company fails to appoint a successor Depositary within 90 days

Event of Default has occurred and is continuing, any owner of a beneficial interest in a Global Note may exchange such beneficial interest for Definitive Notes by delivering a written request to the Company, the Registrar and the Trustee; or 

(II) at any time, the Company may, in its sole discretion, at the request of the owner of a beneficial interest in a Global Note, permit the
exchange of such owner’s beneficial interest, by delivering a written request to the Registrar, the Trustee and the owner of such beneficial interest. 

In each case, (1) upon receipt of such request, the Registrar will promptly deliver written notice of such request to the Company and the

 (d) Transfer and Exchange of Definitive Notes. If Definitive Notes are issued, a Holder may: 

(i) transfer a Definitive Note by: (A) surrendering such Definitive Note for registration of transfer to the Registrar, together with any

Note to be increased by the aggregate principal amount of such Definitive Note, and credit, or cause to be credited, the account of the Person specified in the instructions provided by the exchanging Holder in an amount equal to the aggregate
principal amount of such Definitive Note, in each case, in accordance with the Applicable Procedures. If at the time of such exchange, no Global Notes are then outstanding, the Company, (x) in accordance with Section 2.05 hereof, will
promptly execute and deliver to the Trustee, a new Global Note registered in the name of the Depositary or a nominee of the Depositary, as the case may be, having the appropriate aggregate principal amount, and bearing such legends as such Global

 Section 2.10 Transfer
Restrictions. 
 (a) Restricted Notes. 

(i) General. Each Note (and every security issued in exchange therefor or substitution thereof, except any shares
of Common Stock issued upon conversion thereof, which may bear the Restricted Stock Legend) that bears, or that is required under this Section 2.10 to bear, the Restricted Notes Legend will be deemed a “Restricted Note,” and
will be subject to the restrictions on Transfer set forth in this Indenture (including in the Restricted Notes Legend)  

  
 - 26 - 








 
unless such restrictions on Transfer are eliminated or otherwise waived by written consent of the Company, and each Holder of a Restricted Note, by such Holder’s acceptance of such
Restricted Note, will be deemed to be bound by the restrictions on Transfer applicable to such Note. 
 (ii) When
Restrictions Apply. Except as provided elsewhere in this Indenture (including clause (iii) of this Section 2.10(a)), until the Free Trade Date of a Note, every certificate evidencing such Note (and every security issued in exchange
therefor or substitution thereof, except any shares of Common Stock issued upon the conversion thereof, which may be required to bear the Restricted Stock Legend) will bear the Restricted Notes Legend unless: 

(A) such Note is being Transferred to a person (other than (x) the Company or (y) an affiliate (as defined in Rule
144) of the Company) pursuant to a registration statement that was effective under the Securities Act at the time of such Transfer; or 

(B) such Note is being Transferred to a person (other than (x) the Company or (y) an affiliate (as defined in Rule
144) of the Company) pursuant to an available exemption from the registration requirements of the Securities Act (including Rule 144) and, after such Transfer, such Note will no longer constitute “a restricted security” (within the meaning
of Rule 144), 
 and, in case (B), the Holder effecting such Transfer delivers to the Trustee, the Company and the Registrar any documents or evidence
required pursuant to the Restricted Notes Legend or this Indenture (including, in the case of Definitive Notes, clause (iii) of this Section 2.10(a)). 

(iii) Termination of Transfer Restrictions. 

(I) Except as otherwise provided in this Indenture (including clause (II) of this Section 2.10(a)(iii)) or as permitted under the terms
of the Restricted Notes Legend, if a Holder requests that the Company remove the Restricted Notes Legend from a Definitive Note that is a Restricted Note, the Restricted Notes Legend will not be removed from such Restricted Note unless such Holder
delivers, (1) to each of the Company and the Registrar a transfer certificate in the form attached as Exhibit B hereto and, (2) to each of the Company, the Registrar and the Trustee, any evidence that each of the Company, the
Registrar and the Trustee, as the case may be, reasonably require, that (x) neither the Restricted Notes Legend nor the Transfer restrictions set forth therein are required to ensure that Transfers of such Restricted Note will comply with
applicable law and (y) after such Transfer, such Restricted Note will not be a “restricted security” (within the meaning of Rule 144); provided, however, that, upon provision of such required transfer certificate and
evidence, the Company will permit such Restricted Note to be exchanged in accordance with Section 2.09(d)(ii) hereof for one or more new Definitive Notes that do not bear the Restricted Notes Legend. In addition, upon receipt by the Trustee and
the Registrar of a Company Order specifying that a Note need not bear the Restricted Notes Legend to comply with applicable law, each of the Trustee and the Registrar will permit such Note to be exchanged in accordance with Section 2.09(d)(ii)
hereof for one or more new Definitive Notes that do not bear the Restricted Notes Legend. 

  
 - 27 - 








 (II) At any time on or after the Free Trade Date with respect to a Note, if such Note is
represented by one or more Global Notes that are Restricted Notes, the Company shall remove the Restricted Notes Legend on such Note by: 

(1) providing written notice to the Trustee and the Registrar that the Free Trade Date has occurred and instructing the Trustee to remove the
Restricted Notes Legend from such Global Notes or to deem the Restricted Notes Legend removed; 
 (2) providing written notice to each
owner of a beneficial interest in any of such Global Notes, which notice will state that the Restricted Notes Legend has been removed or has been deemed removed from the applicable Global Note and include the unrestricted CUSIP that will thereafter
apply to such applicable Global Note; 
 (3) providing written notice to the Trustee and the Depositary that the CUSIP number for each such
Global Note will be changed to an unrestricted CUSIP number, which unrestricted CUSIP number will be listed in such notice; 
 (4)
complying with any Applicable Procedures for legend removal; and 
 (5) providing written notice to the Transfer Agent that the Free Trade
Date has occurred, 
 whereupon the Restricted Notes Legend will be deemed removed from such Global Notes.

subsequently held by the Company or an affiliate (as defined in Rule 144) of the Company, the Restricted Notes Legend will be reinstated. 

(b) Restricted Stock. If any shares of Common Stock are issued upon conversion of any Notes, and such shares of Common Stock are
issued prior to the relevant Free Trade Date, then any certificate representing such shares of Common Stock will, upon such issuance, bear the Restricted Stock Legend unless: 

(A) such shares of Common Stock are being issued to a person (other than (x) the Company or (y) an affiliate (as
defined in Rule 144) of the Company) pursuant to a registration statement that is effective under the Securities Act at the time of such issuance; 

(B) such shares of Common Stock are being issued to a person (other than (x) the Company or (y) an affiliate (as
defined in Rule 144) of the Company) pursuant to an available exemption from the registration requirements of the Securities Act such that, upon issuance, such shares of Common Stock will not constitute “restricted securities” (within the
meaning of Rule 144); or 
 (C) the Company delivers written notice to the Transfer Agent stating that the certificate
representing such shares of Common Stock need not bear the Restricted Stock Legend to comply with applicable law.

 Section 2.11 Replacement Notes. 

If (a)(i) a mutilated Note is surrendered to the Registrar or (ii) the Holder of a Note claims that such Note has been lost, destroyed or
stolen and provides the Company and the Trustee with (A) evidence of such loss, theft or destruction that is reasonably satisfactory to the Company and the Trustee and (B) any amount or kind of security or indemnity that either of the
Company or the Trustee request to protect itself from any loss that it may suffer upon replacement of such Note, and, in either case, (b) such Holder satisfies any other reasonable requirements of the Trustee, including the payment of any tax
or other governmental charge that may be imposed in connection with the replacement of such Note, then, unless the Company or the Trustee receives notice that such Note has been acquired by a bona fide purchaser, the Company will, in accordance with
Section 2.05 hereof, promptly execute and deliver to the Trustee, and the Trustee, upon receipt of a Company Order, in accordance with Section 2.05 hereof, and the documents required by Sections 12.03 and 12.04 hereof, will promptly
authenticate and deliver, in the name of such Holder, a replacement Note having the same aggregate principal amount as the Note that was mutilated or claimed to be lost, destroyed or stolen, bearing any restrictive legends required by
Section 2.02 or 2.10 hereof and with a certificate number not contemporaneously outstanding. 
 Every new Note issued pursuant to this
Section 2.11 in exchange for any mutilated Note, or in lieu of any destroyed, lost or stolen Note, will constitute an original contractual obligation of the Company and any other obligor upon the Notes, regardless of whether the mutilated,
destroyed, lost or stolen Note will be at any time enforceable by anyone, and will be entitled to all benefits of (and will be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly
issued hereunder. 
 Section 2.12 Temporary Notes. Until Definitive Notes are ready for delivery, the Company may
execute and the Trustee or an authenticating agent appointed by the Trustee will, upon receipt of a Company Order, authenticate and deliver temporary Notes (printed or lithographed) (“Temporary Notes”). Temporary Notes will be
issuable in any authorized denomination, and substantially in the form of Definitive Notes, 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 will 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 Definitive Notes. Without unreasonable delay the
Company will prepare, execute and deliver to the Trustee or such authenticating agent Definitive Notes (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 2.06 hereof and the Trustee or such authenticating agent will authenticate and deliver in exchange for such Temporary Notes Definitive Notes having an aggregate principal
amount equal to such Temporary Notes. Such exchange will be made by the Company at its own expense and without any charge therefor. Until so exchanged, the Temporary Notes will, in all respects, be entitled to the same benefits and subject to the
same limitations under this Indenture as Definitive Notes authenticated and delivered hereunder.

 Section 2.13 Cancellation. At any time, the Company may deliver Notes to the Trustee
for cancellation. Whenever any Note is surrendered to the Registrar, Conversion Agent or Paying Agent for registration of transfer, exchange, conversion, repurchase, redemption or payment, the Registrar, Conversion Agent or Paying Agent, as the case
may be, will promptly forward such Note to the Trustee. Upon receipt of any such Note, the Trustee, in its customary manner, will promptly cancel and dispose of such Note. The Company may not issue new Notes to replace Notes that it has repurchased,
redeemed, paid or delivered to the Trustee for cancellation or that a Holder has converted pursuant to Article 10 hereof. 

Section 2.14 Outstanding Notes. At any time, Notes outstanding are limited to all Notes authenticated by the Trustee except
(i) those cancelled by it, (ii) those delivered to it for cancellation and (iii) those deemed not outstanding under Sections 3.05, 10.02 and 11.06 hereof and clauses (a) and (b) of this Section 2.14. 

(a) If a Note is replaced pursuant to Section 2.11 hereof, such Note will cease to be outstanding at the time of its replacement unless
the Trustee and the Company receive proof satisfactory to them that such Note is held by a bona fide purchaser. 
 (b) In addition, if the
Company, any other obligor or an Affiliate of the Company or an Affiliate of such other obligor holds a Note, such Note will be disregarded and deemed not to be outstanding for purposes of determining whether the Holders of the requisite aggregate
principal amount of Notes have given or concurred in any request, demand, authorization, direction, notice, consent, waiver or other action hereunder, except that, in determining whether the Trustee shall be protected in relying upon any such
request, demand, authorization, direction, notice, consent or waiver, only Notes that a Trust Officer of the Trustee actually knows to be so owned shall be so disregarded. Subject to the foregoing, only Notes outstanding at the time of any such
determination will be considered in such determination (including determinations pursuant to Article 6 and Article 9 hereof). 

Section 2.15 Persons Deemed Owners. Prior to due presentment of a Note for registration of transfer, the Company, the Trustee and
any agent of the Company or the Trustee may treat the Person in whose name such Note is registered in the Register as the owner of such Note for the purpose of receiving the payment of the principal, Fundamental Change Repurchase Price or Redemption
Price of, and interest, if any, on, such Note, for the purpose of conversion of such Note and for all other purposes whatsoever with respect to such Note, and none of the Company, the Trustee or any agent of the Company or the Trustee will be
affected by any notice to the contrary. 
 Section 2.16 Repurchases. The Company may, from time to time, repurchase Notes in
open market purchases or in negotiated transactions without delivering prior notice to Holders. 
 Section 2.17 CUSIPs. 

(a) Whenever “CUSIP” and “ISIN” numbers are generally in use, the Company will use CUSIP and ISIN numbers with
respect to the Notes, which CUSIP and ISIN numbers (i) for Restricted Notes, will be restricted numbers, and (ii) for Notes that are not Restricted Notes, will be unrestricted numbers. Whenever the Company uses CUSIP and ISIN numbers, the
Trustee will also use CUSIP and ISIN numbers in each notice it delivers to the Holders; provided, that  

  
 - 30 - 








 
neither the Company nor the Trustee will be responsible for any defect in any CUSIP or ISIN number that appears on any Note, check, advice of payment or notice, including any notice delivered
pursuant to Section 11.03. The Company will promptly notify the Trustee in writing in the event of any change in the CUSIP or ISIN numbers. 

(b) In addition, if, when any shares of Common Stock are issued upon conversion of a Note, CUSIP and ISIN numbers are generally in use, the
Company will use CUSIP and ISIN numbers with respect to such shares of Common Stock, which CUSIP and ISIN numbers (i) for shares of Common Stock to which the restrictions on Transfer set forth in the Restricted Stock Legend apply, will be
restricted numbers, and (ii) for shares of Common Stock to which the restrictions on Transfer set forth in the Restricted Stock Legend do not apply, will be unrestricted numbers. 

(c) Whenever any of the CUSIP or ISIN numbers with respect to the Notes or the shares of Common Stock issuable upon conversion of the Notes
change, cease to be used, or begin to be used, the Company will deliver prompt written notice of such change, cessation, or beginning to each of the Trustee and the Holders.

Change Repurchase Notice; 
 (L) the procedures for withdrawing a Fundamental Change Repurchase Notice; 

(M) that if a Note or portion of a Note is subject to a validly delivered Fundamental Change Repurchase Notice, unless the

(N) the CUSIP and ISIN number(s) of the Notes. 

(b) Failure or Defect. Notwithstanding anything provided elsewhere in this Indenture, neither the failure of the Company to

the repurchase of any Note pursuant to this Article 3. 
 (c) Third Party Offer. Notwithstanding the other provisions
of this Article 3, the Company will not be required to make an offer to purchase the Notes upon a Fundamental Change if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements in this Indenture

(b) Timing of Payment. Upon the Paying Agent’s receipt of (i) a valid Fundamental Change Repurchase Notice (together
with all necessary endorsements) and (ii) the Notes to which such Fundamental Change Repurchase Notice pertains, the Holder of the Notes to which such Fundamental Change Repurchase Notice pertains will be entitled, except to the extent such

 Section 3.06 Notes Repurchased in Part. If any Definitive Note is to be repurchased
only in part, the Holder must surrender such Note at the office of the Paying Agent, whereupon the Company, in accordance with Section 2.05 hereof, will promptly execute, and the Trustee, in accordance with Section 2.05 hereof, will
promptly authenticate and deliver, to the surrendering Holder, a new Note or Notes of any authorized denomination or denominations equal to the portion of the principal amount of the Note so surrendered which is not repurchased. If any Global Note

Change Repurchase Date. 
 Section 3.09 Covenant Not to Repurchase Notes Upon Certain Events of Default.

Company’s payment of the Fundamental Change Repurchase Price. 
 (b) Deemed Withdrawals. If, on any Fundamental

 COVENANTS

 Section 4.01 Payment of Notes. The Company will pay or cause to be paid the principal of, Fundamental Change Repurchase
Price or Redemption Price for, and any accrued and unpaid interest on, the Notes on the dates and in the manner required under this Indenture. Any principal of, Fundamental Change Repurchase Price or Redemption Price for, or interest on, a Note will
be considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary thereof, holds, as of 11:00 a.m. New York City time on the due date, money deposited by the Company in immediately available funds and designated for,
and sufficient to pay, such principal, Fundamental Change Repurchase Price, Redemption Price or interest then due. To the extent lawful, the Company will also pay Default Interest on any Defaulted Amounts in accordance with Section 2.04 hereof.

 Section 4.02 144A Information. Whenever the Company is not subject to Section 13 or Section 15(d) of the Exchange
Act, if any Notes or shares of Common Stock, if any, issuable upon the conversion of the Notes constitute “restricted securities” within the meaning of Rule 144, the Company will, upon the request of a Holder or beneficial owner of the
Notes, or a holder or beneficial owner of the Common Stock, if any, issuable upon the conversion of the Notes, promptly furnish or cause to be furnished to the applicable Holder, beneficial owner, or any prospective purchaser designated by the
applicable Holder or beneficial owner, of the Notes, or any holder, beneficial owner, or any prospective purchaser designated by the applicable holder or beneficial owner, of the Common Stock, as the case may be, all of the information that a
prospective purchaser of the Notes or the Common Stock, as the case may be, is required to receive under Rule 144A(d)(4) of the Securities Act for the Notes or shares of Common Stock, as the case may be, to be resold to such prospective purchaser
pursuant the exemption from registration provided by Rule 144A. 
 Section 4.03 Reports. The Company will deliver to Holders,
with a copy to the Trustee, copies of all quarterly and annual reports that the Company is required to deliver to the SEC on Forms 10-Q and 10-K, and any other documents, information or other reports that the Company is required to file with the SEC
under Sections 13 or 15(d) of the Exchange Act no later than 15 days after the time that the Company is required to file such quarterly and annual reports, other documents, information or other reports with the SEC (after giving effect to any grace
period provided by Rule 12b-25 under the Exchange Act). Any document filed by the Company with the SEC via the EDGAR system (or any successor thereto) will be deemed to be delivered to Holders and the Trustee at the time such document is filed via
the EDGAR system (or such 

  
 - 37 - 








 
successor); provided, however, that the Trustee will have no responsibility whatsoever to determine whether the Company has made any filing via the EDGAR system (or any successor thereto).
Notwithstanding anything to the contrary in the foregoing, nothing in this paragraph shall require the Company to deliver to any Holder or the Trustee any material for which the Company has sought and received, or is seeking and has not been denied,
confidential treatment by the SEC. 
 Delivery of such quarterly and annual reports, and such other documents, information and other reports
to the Trustee will be for informational purposes only, and the Trustee’s receipt of such will not constitute constructive notice of any information contained therein or determinable from information contained therein, including the
Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely conclusively on Officers’ Certificates). 

Section 4.04 Additional Interest. 

(a) General. If, at any time during the period beginning on, and including, the date that is six months after the
Last Original Issue Date and ending on, but not including, the Free Trade Date, the Company fails to timely file (after giving effect to any grace period provided by Rule 12b-25) any document or report that it is required to file with the SEC
pursuant to Sections 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than current reports on Form 8-K), the Company will pay additional interest (the “Additional
Interest”) on the principal amount of then outstanding Notes. The Additional Interest will accrue from the due date of each such missed filing until the earlier of (i) the Free Trade Date and (ii) the date such failure to file is
corrected. 
 In addition, if either the Notes or the Common Stock, if any, issued upon the conversion of the Notes are not Freely
Tradable at all times as of the 10th day after the Free Trade Date (or the next succeeding Business Day if the Free Trade Date is not a Business Day), the Company will pay Additional Interest on the Notes. Such Additional Interest will accrue on
each day during such period on which the Notes or the Common Stock issued upon conversion of the Notes are not Freely Tradable. The accrual of Additional Interest will be the exclusive remedy available to Holders for the failure of the Notes or the
Common Stock, if any, issued upon the conversion of the Notes to become Freely Tradable. 
 In each case, the Additional Interest will be
payable on the same dates and in the same manner as the stated interest on the Notes and will initially accrue at the rate of 0.25% per annum on the principal amount of then outstanding Notes. If the Additional Interest accrues for more than 90
consecutive days, the rate at which the Additional Interest accrues will increase to 0.50% per annum on the principal amount of then outstanding Notes beginning on the 91st consecutive day on
which it accrues and ending on the last consecutive day on which it continues to accrue. The Company shall provide written notice to the Holders and the Trustee of the commencement of any period which Additional Interest shall accrue. 

Notwithstanding the foregoing, in no event will any Additional Interest that may accrue pursuant to the immediately preceding paragraph,
together with any Extension Fee, accrue, in the aggregate, at a rate in excess of 0.50% per annum, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest and/or Extension Fee. 

  
 - 38 - 








 (b) Notice to Trustee. If the Company is required to pay Additional Interest on any
Note, no later than five Business Days prior to the date on which such Additional Interest is scheduled to be paid, the Company will provide to the Trustee (and if the Trustee is not the Paying Agent, to the Paying Agent) an Officers’
Certificate, which Officers’ Certificate will state (i) that the Company is obligated to pay Additional Interest pursuant to this Section 4.04, (ii) the amount of such Additional Interest that the Company is required to pay under
this Section 4.04, (iii) the amount of such Additional Interest that the Company will pay, (iv) the scheduled date on which such Additional Interest will be paid to Holders and (v) a direction that the Trustee (or, if the Trustee
is not the Paying Agent, the Paying Agent) pay such Additional Interest to the extent it receives funds from the Company to do so, on the scheduled payment date for such Additional Interest. The Trustee will not have any duty or responsibility to
any Holder to determine whether any Additional Interest is payable, or, if any Additional Interest is payable, the amount of such Additional Interest that is payable. 

Section 4.05 Compliance Certificate. 

(a) Annual Compliance Certificate. Within 90 days after the end of each fiscal year of the Company, beginning with the fiscal
year ending on January 31, 2015, the Company will deliver to the Trustee an Officers’ Certificate, which Officers’ Certificate will state (i) that the Officers signing such Officers’ Certificate have supervised a review of
the activities of the Company and the Subsidiaries with a view to determining whether the Company has kept, observed, performed and fulfilled its obligations under this Indenture during the preceding fiscal year, and (ii) to the best knowledge
of each of the Officers signing such Officers’ Certificate, (A) whether the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of

Defaults or Events of Default and what actions the Company is taking or proposes to take with respect to such Defaults or Events of Default, and (B) whether any event has occurred and remains in existence by reason of which any payment of the
principal of, the Fundamental Change Repurchase Price or the Redemption Price for, or interest on, or any delivery of any of the consideration due upon conversion of, a Note is prohibited, and, if any such event has occurred and remains in

 (vii) the
default by the Company or any Subsidiary with respect to any mortgage, agreement or other instrument under which there may be outstanding, or by which 

  
 - 42 - 








 
there may be secured or evidenced, any indebtedness for money borrowed by the Company and/or any Subsidiary in excess of $10,000,000 in the aggregate, whether such indebtedness exists as of the
Issue Date or is later created, if that default: 
 (A) results in such indebtedness becoming or being declared due and
payable (prior to its express maturity); or 
 (B) constitutes a failure to pay the principal of, or interest on, such
indebtedness when due and payable at its stated maturity, upon required repurchase, upon declaration or otherwise; 
 (viii) a final

to appeal such judgment have expired if no appeal has commenced, or (ii) the date on which all rights to appeal have been extinguished; 

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

 - 43 - 








 (D) grants any similar relief under any foreign laws; 

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

(b) Cause Irrelevant. Each of the events enumerated in Section 6.01(a) hereof will constitute an Event of Default whatever
the cause and regardless of whether voluntary or involuntary or effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body. 

Section 6.02 Acceleration. 

(a) Automatic Acceleration in Certain Circumstances. If an Event of Default specified in Sections 6.01(a)(ix) or 6.01(a)(x)
hereof occurs with respect to the Company, the principal amount of, and all accrued and unpaid interest, if any, on, all of the then outstanding Notes will immediately become due and payable without any further action or notice by any party.

 (b) Optional Acceleration. If any other Event of Default occurs and is continuing, the Trustee, by delivering a written
notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, by delivering a written notice to the Company and the Trustee, may declare the principal amount of, and all accrued and unpaid
interest, if any, on all then outstanding Notes immediately due and payable, and upon such declaration, the principal amount of, and all accrued and unpaid interest, if any, on all then outstanding Notes will immediately become due and payable.

 (c) Rescission of Acceleration. Notwithstanding anything to the contrary in this Indenture, the Holders of a majority
of the aggregate principal amount of the then outstanding Notes may, on behalf of the Holders of all of the then outstanding Notes, rescind any acceleration of the Notes and its consequences hereunder by delivering notice to the Trustee if
(i) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (ii) all existing Events of Default (other than the nonpayment of the principal of, interest, if any, on, or the Fundamental Change
Repurchase Price or the Redemption Price for, the Notes that has become due solely as a result of acceleration) have been cured or waived. No such rescission will affect any subsequent Default or impair any right consequent thereto. 

Section 6.03 Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to
collect the payment of principal, accrued and unpaid interest, if any, or payment of the Fundamental Change Repurchase Price or Redemption Price for, the Notes or to enforce the performance of any provision of the Notes or this Indenture regarding
any other matter. 
 The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of the Notes
in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default will not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy
is exclusive of any other remedy. All available remedies are cumulative. 

  
 - 44 - 








 Section 6.04 Sole Remedy for Failure to Report. 

(a) General. Notwithstanding anything to the contrary in the Notes or in this Indenture, the Company may elect
that the sole remedy for any Event of Default specified in Section 6.01(a)(vi) hereof relating to the Company’s failure to comply with Section 4.03 hereof (a “Reporting Event of Default”) will, for the period
beginning on the date on which such Reporting Event of Default first occurred and ending on the earlier of (A) the date on which such Reporting Event of Default is cured or validly waived in accordance with Section 6.05 hereof and
(B) the 180th calendar day immediately following the date on which such Reporting Event of Default first occurred, consist exclusively of the right to receive additional interest (the “Extension Fee”) on the Notes at a rate
equal to 0.25% per annum of the principal amount of the Notes outstanding for each day during the first 90 days after the occurrence of such Reporting Event of Default and 0.50% per annum on the principal amount of the then-outstanding
Notes for each day during the period from the 91st day through, and including, the 180th day following the occurrence of such Reporting Event Default during which such Reporting Event Default is continuing. Any Extension Fee will be payable in the
same manner and on the same dates as the stated interest payable on the Notes and will accrue in addition to any Additional Interest that the Company is obligated to pay under Section 4.04 hereof. 

(b) Limitation on Remedy. If (i) a Reporting Event of Default occurs and the Company elects that the sole remedy with
respect to such Reporting Event of Default will be the Extension Fee and (ii) on the 181st day immediately following, and including, the date on which such Reporting Event of Default first occurred, such Reporting Event of Default has not been
cured or validly waived in accordance with Section 6.05 hereof, then the Notes will become subject to acceleration under Section 6.02(a) hereof on account of such Reporting Event of Default. 

(c) Company Election Notice. To elect to pay the Extension Fee as the sole remedy for a Reporting Event of Default, the Company
must deliver written notice of such election to the Holders, the Paying Agent and the Trustee prior to the date on which such Reporting Event of Default first occurs. Any such notice must include a brief description of the report that the Company
failed, or will fail, to file, a statement that the Company is electing to pay the Extension Fee and the date on which such Reporting Event of Default will occur. 

If a Reporting Event of Default occurs and the Company fails to timely deliver such notice for such Reporting Event of Default, the Notes will
be subject to acceleration under Section 6.02(a) hereof on account of such Reporting Event of Default. 
 (d) Other Events of
Default. Notwithstanding anything to the contrary herein, if the Company elects to pay the Extension Fee with respect to any Reporting Event of Default, the Company’s election will not affect the rights of any Holder with respect to any
other Event of Default, including with respect to any other Reporting Event of Default; provided, that, for the avoidance of doubt, in no event will the Company be obligated to pay the Extension Fee at a rate greater than 0.50% per annum
on the principal amount of then outstanding Notes. 
 Notwithstanding the foregoing, in no event will any Extension Fee that may
accrue pursuant to this Section 6.04, together with any Additional Interest that may accrue pursuant to 

  
 - 45 - 








 
Section 4.04(a), accrue, in the aggregate, at a rate in excess of 0.50% per annum, regardless of the number of events or circumstances giving rise to the requirement to pay such
Extension Fee and/or Additional Interest. 
 Section 6.05 Waiver of Past Defaults. If an Event of Default described in Sections
6.01(a)(i), 6.01(a)(ii), 6.01(a)(iv) or 6.01(a)(vi) (which, in the case of Section 6.01(a)(vi) only, relates to a covenant that cannot be amended without the consent of each affected Holder) or a Default that would lead to such an Event of
Default occurs and is continuing, such Event of Default or Default may be waived only with the consent of each affected Holder. Every other Event of Default or Default may be waived by the Holders of a majority of the aggregate principal amount of
then outstanding Notes (including consents obtained in connection with a repurchase of, or tender offer or exchange offer for, Notes). Whenever any Event of Default is so waived, it will cease to exist, and whenever any Default is so waived, it will
be deemed cured and any Event of Default arising therefrom will be deemed not to occur. However, no such waiver will extend to any subsequent or other Default or Event of Default or impair any consequent right. 

Section 6.06 Control by Majority. At any time, the Holders of a majority of the aggregate principal amount of then outstanding
Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or for exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts
with law or this Indenture or, subject to Section 7.01 hereof, that the Trustee determines to be unduly prejudicial to the rights of a Holder or to the Trustee, or that would potentially involve the Trustee in personal liability unless the
Trustee is offered indemnity or security satisfactory to it against any loss, liability or expense to the Trustee that may result from the Trustee’s instituting such proceeding as the Trustee. Prior to taking any action hereunder, the Trustee
will be entitled to indemnification satisfactory to it against all losses, liabilities and expenses caused by taking or not taking such action. 

Section 6.07 Limitation on Suits. Except to enforce (i) its rights to receive the principal of, the Fundamental Change
Repurchase Price or the Redemption Price for, interest, if any, on, a Note, or (ii) the failure of the Company to comply with its obligations under Article 10 to convert any Note, no Holder may pursue a remedy with respect to this Indenture or
the Notes unless: 
 (a) such Holder has previously delivered to the Trustee written notice that an Event of Default has occurred and is
continuing; 
 (b) the Holders of at least 25% of the aggregate principal amount of then-outstanding Notes deliver to the Trustee a written
request that the Trustee pursue a remedy with respect to such Event of Default; 
 (c) such Holder or Holders have offered and, if
requested, provided, to the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or other expense of compliance with such written request; 

  
 - 46 - 








 (d) the Trustee has not complied with such written request within 60 days after receipt of such
written request and offer of security or indemnity; and 
 (e) during such 60-day period, the Holders of a majority of the aggregate
principal amount of then outstanding Notes did not deliver to the Trustee a direction inconsistent with such written request. 
 A Holder
may not use this Indenture to prejudice the rights of any other Holder or to obtain a preference or priority over any other Holder, it being understood that the Trustee does not have any affirmative duty to ascertain whether any usage of this
Indenture by a Holder is unduly prejudicial to such other Holders. 
 Section 6.08 Rights of Holders To Receive Payment.
Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of the principal of, the Fundamental Change Repurchase Price or the Redemption Price for, accrued and unpaid interest, if any, on, and any
consideration due under Article 10 upon conversion of, its Note, on or after the respective due date, or to bring suit for the enforcement of any such payment and/or delivery on or after the respective due date, will not be impaired or affected
without the consent of such Holder and will not be subject to the requirements of Section 6.07 hereof. 
 Section 6.09
Collection Suit by Trustee. If an Event of Default specified in Sections 6.01(a)(i), 6.01(a)(ii), or 6.01(a)(iv) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust
against the Company for the whole amount of principal of, the Fundamental Change Repurchase Price or the Redemption Price for, interest, if any, on, and the Conversion Consideration, if any, due upon conversion of, the Notes, and, to the extent
lawful, any Default Interest on any Defaulted Amounts, and such further amount as is sufficient to cover the costs and expenses of collection provided for under Section 7.06 hereof. 

Section 6.10 Trustee May File Proofs of Claim. The Trustee is authorized to file such proofs of claim and other papers or
documents as may be necessary or advisable to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company, its creditors or its property and, unless prohibited by law or applicable regulations, will be
entitled to collect, receive and distribute any money or other property payable or deliverable on any such claims, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the
event that the Trustee consents to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any
other amounts due the Trustee under Section 7.06 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.06 hereof out of the estate in any such proceeding, will be denied for any reason, payment of the same will be secured by a lien on, and will be paid out of, any and all distributions, dividends, money, securities and other properties
that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained will be deemed to authorize the Trustee to authorize or consent to, or to
accept or to adopt on behalf of any Holder, any plan of 

  
 - 47 - 








 
reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding. 
 Section 6.11 Priorities. If the Trustee collects any money or property pursuant to this Article 6, it will pay
out the money or property in the following order: 
 FIRST: to the Trustee, its agents and attorneys for amounts due under Section 7.06
hereof, including payment of all fees, compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

SECOND: to the Holders, for any amounts due and unpaid on the principal of, the Fundamental Change Repurchase Price or the Redemption Price
for, accrued and unpaid interest on, and any Conversion Consideration due upon the conversion of, any Note, without preference or priority of any kind, according to such amounts due and payable on all of the Notes; and 

THIRD: the balance, if any, to the Company or to such other party as a court of competent jurisdiction directs. 

The Trustee may fix a record date and payment date for any payment to the Holders pursuant to this Section 6.11. If the Trustee so fixes
a record date and a payment date, at least 15 days prior to such record date, the Company will deliver to each Holder and the Trustee a written notice, which notice will state such record date, such payment date and the amount of such payment. 

Section 6.12 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit
against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess
reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.12 does not
apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.08 hereof or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes. 

ARTICLE 7 
 TRUSTEE

 Section 7.01 Duties of Trustee. 

(a) If an Event of Default has occurred and is continuing, the Trustee will exercise the rights and powers vested in it by this Indenture, and

of its Trust Officers in good faith determines that withholding the notice is in the interests of Holders. 
 Section 7.06
Compensation and Indemnity. 
 (a) The Company will pay to the Trustee, from time to time, such compensation as will be agreed upon,
from time to time, in writing for its services. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Company will reimburse the Trustee upon request for all reasonable out-of-pocket
fees and expenses incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses will include the reasonable compensation, fees and expenses, disbursements and advances of the Trustee’s
agents, counsel, accountants and experts. The Company will fully indemnify the Trustee and hold it harmless against any and all loss, liability, claims (including those between the parties to this Indenture), damages or expenses (including
reasonable attorneys’ fees and expenses) incurred by it in connection with the acceptance and administration of this trust and the performance of its duties hereunder, including the costs and expenses of defending itself against any claim
(whether asserted by the Company, any Holder or any other Person). The Trustee will notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company of any claim for which it may seek
indemnity of which a Trust Officer has actually received written notice will not relieve the Company of its obligations hereunder except to the extent such failure is adjudicated by a court of competent jurisdiction to have materially prejudiced the
Company. The Company will defend the claim and the Trustee will cooperate in the defense. If the Trustee is advised by counsel that it may have available to it defenses that are in conflict with the defenses available to the Company or that there is
an actual or potential conflict of interest, then the Trustee may have separate counsel, and the Company will pay the reasonable fees and expenses of such counsel. The Company will pay the reasonable fees and expenses of counsel to the Trustee
incurred in 

  
 - 51 - 








 
evaluating whether such defense and/or conflict exists. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the
Trustee’s own willful misconduct or negligence. The Company need not pay for any settlement made by the Trustee without the Company’s consent, such consent not to be unreasonably withheld. All indemnifications and releases from liability
granted hereunder to the Trustee will extend to its officers, directors, employees, agents, attorneys, custodians, successors and assigns. In no event shall the Company have the right, without the related Trustee’s written consent, to settle
any such claim if such settlement (i) arises from or is part of any criminal action, suit or proceeding, (ii) contains a stipulation to, confession of judgment with respect to, or admission or acknowledgement of, any liability or
wrongdoing on the part of such the Trustee, (iii) provides for injunctive relief or specific performance on the part of the Trustee or any other relief other than monetary damages payable in full by the Company or (iv) does not contain an
unconditional release of the Trustee from all liability on all claims that are the subject matter of the related dispute or proceeding. 

(b) To secure the Company’s payment obligations under this Section 7.06, the Trustee will have a lien prior to the Notes on all
money or property held or collected by the Trustee, other than money or property held in trust to pay the principal, accrued and unpaid interest, if any, or payment of the Fundamental Change Repurchase Price or Redemption Price on particular Notes.

 (c) The Company’s payment obligations pursuant to this Section 7.06 will survive the resignation or removal of the Trustee and
the discharge of this Indenture. If the Trustee incurs expenses after the occurrence of a Default specified in Sections 6.01(a)(ix) or 6.01(a)(x) hereof with respect to the Company, the expenses are intended to constitute expenses of administration
under the Bankruptcy Law. 
 Section 7.07 Replacement of Trustee. 

(a) The Trustee may resign at any time by notifying the Company, in writing, at least 30 days prior to the proposed resignation. The Holders
of a majority in aggregate principal amount of then outstanding Notes may remove the Trustee by notifying the Trustee, in writing. The Company may remove the Trustee if: 

(i) the Trustee fails to comply with Section 7.09 hereof; 

(ii) the Trustee is adjudged bankrupt or insolvent; 

(iii) a receiver or other public officer takes charge of the Trustee or its property; or 

(iv) the Trustee otherwise becomes incapable of acting. 

(b) If the Trustee resigns, is removed by the Company or by the Holders of a majority in aggregate principal amount of the Notes then
outstanding, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company will promptly appoint a successor Trustee. 

  
 - 52 - 








 (c) A successor Trustee will deliver a written acceptance of its appointment to the retiring
Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will
send a notice of its succession to Holders. The retiring Trustee will, upon payment of all of its costs and the costs of its agents and counsel, promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 7.06 hereof. 
 (d) If a successor Trustee does not take office within 60 days after the retiring Trustee
resigns or is removed, the retiring Trustee, the Company or the Holders of at least 10% of the aggregate principal amount of the Notes then outstanding may petition, at the expense of the Company, any court of competent jurisdiction for the
appointment of a successor Trustee. 
 (e) If the Trustee, after written request by any Holder, fails to comply with Section 7.09
hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

(f) Notwithstanding the replacement of the Trustee pursuant to this Section 7.07, the Company’s obligations under Section 7.06
hereof will continue for the benefit of the retiring Trustee. 
 Section 7.08 Successor Trustee by Merger. 

(a) If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets
to, another corporation or banking association, the resulting, surviving or transferee corporation or banking association without any further act will be the successor Trustee. 

(b) In case at the time such successor or successors by merger, conversion or consolidation to the Trustee succeeds to the trusts created by
this Indenture, any of the Notes have been authenticated, but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee, and deliver such Notes so authenticated; and, in case at that time
any of the Notes have not been authenticated, any such successor to the Trustee may authenticate such Notes, either in the name of any predecessor Trustee hereunder or in the name of the successor to the Trustee. 

Section 7.09 Eligibility; Disqualification. The Trustee will have (or, in the case of a corporation included in a bank holding
company system, the related bank holding company will have) a combined capital and surplus of at least $100,000,000, as set forth in its (or its related bank holding company’s) most recent published annual report of condition. 

Section 7.10 Trustee’s Application for Instructions from the Company. Any application by the Trustee for written instructions
from the Company 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 will be taken or such omission will be effective.
The Trustee will not be liable to the Company 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 will not be less than three
Business Days after the date any 

  
 - 53 - 








 
Officer actually receives such application, unless any such Officer has 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 has received written instructions in response to such application specifying the action to be taken or omitted. 

ARTICLE 8

Notwithstanding the satisfaction and discharge of this Indenture, (i) any obligation of the Company to any Holder under Article 10 hereof
with respect to the conversion of any Note or to the Trustee under Article 7 hereof with respect to compensation or indemnity, and (ii) any obligation of the Trustee with respect to money deposited with the Trustee under this Article 8 and
Section 12.02 hereof will survive.

rights, duties, liabilities or immunities under this Indenture, then the Trustee may, but need not, sign such supplemental indenture. In executing any such supplemental indenture, the Trustee will be provided with, and, subject to the provisions of
Section 7.01 hereof, will be fully protected in conclusively relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such supplemental indenture is authorized and permitted under this Indenture and that all conditions

 - 56 - 








 
amendment or supplement to this Indenture in reasonable detail and state the effective date of such amendment or supplement. The failure to deliver such notice to each Holder, or any defect in

Section 9.06 Revocation and Effect of Consents, Waivers and Actions. 

(a) Revocation. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent
by the Holder, and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder, or subsequent Holder, may
revoke the consent as to its Note or portion of a Note if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective. 

(b) Special Record Dates. The Company may, but is not obligated to, fix a record date for the purpose of determining the Holders
entitled to give their consent or take any other action described above or required, or permitted, to be taken pursuant to this Indenture. If a record date is fixed, then those Persons who were Holders at such record date (or their duly designated
proxies), and only those Persons, will be entitled to give such consent, to revoke any consent previously given or to take any such action, regardless of whether such Persons continue to be Holders after such record date. No such consent will be

 ARTICLE 10 

CONVERSIONS 

Section 10.01 Right To Convert. 

(a) In General. Subject to, and upon compliance with, the provisions of this Article 10, a Holder may, at its option, convert
all of its Notes, or any portion of its Notes having a principal amount equal to $1,000 or an integral multiple of $1,000 in excess thereof, (i) subject to satisfaction of the conditions set forth in Section 10.01(b), at any time prior to
the Close of Business on the Business Day immediately preceding April 1, 2019, under the circumstances and during the periods set forth in Section 10.01(b), and (ii) irrespective of the conditions set forth in Section 10.01(b),
on or after April 1, 2019, and prior to the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date, in each case, into Conversion Consideration, as provided in this Article 10, based on the Conversion
Rate. Notes may not be converted after the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date. 

(b) Conditions to Conversions Prior to the Close of Business on the Business Day Immediately Preceding April 1, 2019. Prior
to the Close of Business on the Business Day immediately preceding April 1, 2019, no Notes may be converted except under the circumstances and during the periods set forth below in this Section 10.01(b). 

(i) Conversion Upon Satisfaction of Sale Price Condition. Prior to the Close of Business on the Business Day immediately
preceding April 1, 2019, a Holder may present its Notes for conversion during any fiscal quarter commencing after the fiscal quarter ending on January 31, 2015 (and only during such fiscal quarter), if the Last Reported Sale Price per
share of the Common Stock for each of at least 20 Trading Days (whether or not consecutive) during the 30 consecutive Trading days ending on, and including, the last Trading Day of the immediately preceding fiscal quarter is greater than 130% of the
Conversion Price on such Trading Day. 
 (ii) Conversion Upon Satisfaction of Trading Price Condition. Prior to the
Close of Business on the Business Day immediately preceding April 1, 2019, a Holder may convert its Notes during the five consecutive Business Day period immediately after any five consecutive Trading Day period (such five consecutive Trading
Day period, the “Measurement Period”) in which the Trading Price per $1,000 principal amount of the Notes, as determined following a written request by a Holder in accordance with the procedures set forth below, for
each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on such Trading Day. The condition set forth in the preceding sentence is herein referred to as
the “Trading Price Condition.” 
 The Trading Price shall be determined by the Bid Solicitation Agent
pursuant to this Section 10.01(b)(ii) and the definition of Trading Price set forth herein. The Bid Solicitation Agent (if other than the Company) shall have no obligation to determine the Trading Price per $1,000 principal amount of the Notes
unless the Company has requested such determination in writing, and the Company will have no obligation to make such request (or seek bids itself) 

  
 - 58 - 








 
unless a Holder of at least $2,000,000 aggregate principal amount of Notes provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of the Notes would be
less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate. At such time, the Company shall, or shall instruct the Bid Solicitation Agent to, determine the Trading Price per $1,000 principal amount of
the Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of the 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. If the Trading Price condition has been met, the Company will so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing. If, on any Trading Day 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 Trading Day, the Company will so notify the Holders, the
Trustee and the Conversion Agent (if other than the Trustee) in writing. 
 (iii) Conversion Upon Specified Corporate
Events. 
 (A) Certain Distributions. If the Company elects to: 

(I) issue, to all or substantially all holders of the Common Stock, any rights, options or warrants entitling them, for a period of not more
than 60 calendar days after the record 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, and including, the Trading Day immediately preceding the date of announcement of such issuance; or 
 (II) distribute, to
all or substantially all holders of the Common Stock, the Company’s assets, debt securities or rights to purchase the Company’s securities, 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 immediately preceding the date of announcement for such distribution, 

then, in either case, (x) the Company must notify Holders (with a copy to the Trustee and the Paying Agent) at least 30 Scheduled Trading Days prior to
the Ex-Dividend Date for such issuance or distribution; and (y) once the Company has given such notice, Holders may convert their Notes at any time until the earlier of the Close of Business on the Business Day immediately preceding such
Ex-Dividend Date and the Company’s announcement that such issuance or distribution will not take place. 
 (B)
Certain Corporate Events. If, either (i) a transaction or event that constitutes a Fundamental Change occurs; (ii) a transaction or event that constitutes a Make-Whole Fundamental Change occurs; or (iii) the Company is a party
to a consolidation, merger, binding share exchange, or a transfer or lease of all or substantially all of the Company’s assets, or any other transaction, in each case pursuant to which the Common Stock would be converted into or exchanged for,
or would constitute solely the right to receive, cash, securities or other property, then the Notes may be converted at any time from and after the effective date of the transaction or event 

  
 - 59 - 








 
until the earlier of (x) 35 Trading Days after the actual effective date of such transaction or event (or, if later, the date on which the Company provides notice of such transaction or
event) or, if such transaction or event also constitutes a Fundamental Change, the related Fundamental Change Repurchase Date; and (y) the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date. No later
than the Business Day after the date the Company publicly announces such transaction or event, the Company shall notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing of such transaction, its effective date
and the related right to convert Notes. 
 (iv) Conversion Based on Redemption. If the Company calls a Note for
Redemption, then the Holder of such Note may surrender the Note for conversion at any time before the Close of Business on the second Business Day immediately preceding the Redemption Date. 

(c) Closed Periods. Notwithstanding anything to the contrary in this Indenture, (i) if the Company calls the Notes for
redemption in accordance with Article 11 hereof, a Holder may not convert its Notes after the Close of Business on the Business Day immediately preceding the applicable Redemption Date except to the extent the Company fails to pay the Redemption
Price for such Notes in accordance with Section 11.05 hereof, and (ii) if a Holder tenders a Repurchase Notice with respect to its Notes in accordance with Article 3 hereof, such Notes may not be converted except to the extent
(A) such Notes are not subject to such Repurchase Notice; (B) such Repurchase Notice is withdrawn in accordance with Article 3 hereof; or (C) the Company fails to pay the Fundamental Change Repurchase Price for such Notes in
accordance with Section 3.08 hereof. 
 Section 10.02 Conversion Procedures. 

(a) General. To exercise its conversion right with respect to a beneficial interest in a Global Note, the owner of such
beneficial interest must (i) comply with the Applicable Procedures for converting such beneficial interest; (ii) pay any funds equal to interest payable on the next Interest Payment Date that such Holder is required to pay under clause
(d) of this Section 10.02; and (iii) pay any taxes or duties that such Holder is required to pay under the proviso to clause (e) of this Section 10.02. 

To exercise its conversion right with respect to a Definitive Note, the Holder of such Note must (i) complete and manually sign
the conversion notice on the back of the Note, or a facsimile of such conversion notice (such notice, or such facsimile, the “Conversion Notice”); (ii) deliver such signed and completed Conversion Notice, which shall be
irrevocable, and such Note to the Conversion Agent at its office; (iii) furnish any endorsements and transfer documents that the Company, Conversion Agent, Trustee or Transfer Agent may require; (iv) pay any funds equal to interest payable
on the next Interest Payment Date that such Holder is required to pay under clause (d) of this Section 10.02; and (v) pay any taxes or duties that such Holder is required to pay under the proviso to clause (e) of this Section
10.02. 

  
 - 60 - 








 The first Business Day on which a Holder satisfies the foregoing requirements with respect
to a Note and on which conversion of such Note is not otherwise prohibited under this Indenture will be the “Conversion Date” for such Note. 

The conversion of any Note will be deemed to occur at the Close of Business on the Conversion Date for such Note, and any converted Note or
portion thereof will cease to be outstanding upon conversion. 
 (b) Holder of Record. If a Holder surrenders the entire
principal amount of a Note for conversion, such Person will no longer be the Holder of such Note as of the Close of Business on the Conversion Date for such Note. 

The Person in whose name any shares of Common Stock shall be issuable upon conversion of any Note will become the holder of record of such
shares as of the Close of Business on the Conversion Date for such conversion, in the case of Physical Settlement, or the last Trading Day of the relevant Observation Period, in the case of Combination Settlement. 

(c) Conversions in Part. If a Holder surrenders only a portion of the principal amount of a Definitive Note for conversion,
promptly after the Conversion Date for such portion, the Company will, in accordance with Section 2.05 hereof, execute and deliver to the Trustee, and the Trustee will, upon receipt of a Company Order, in accordance with Section 2.05
hereof, authenticate and deliver to such Holder a new Definitive Note in an authorized denomination, having a principal amount equal to the aggregate principal amount of the unconverted portion of the Definitive Note surrendered for conversion and
bearing registration numbers not contemporaneously outstanding and any restrictive legends that such Definitive Note must bear under Section 2.10 hereof. 

Upon the conversion of any beneficial interest in a Global Note, the Conversion Agent will promptly request that the Trustee make a notation
on the “Schedule of Increases and Decreases of Global Note” of such Global Note to reduce the principal amount represented by such Global Note by the principal amount of the converted beneficial interest. If all of the beneficial interests
in a Global Note are so converted, such Global Note will be deemed surrendered to the Trustee for cancellation, and the Trustee will cause such Global Note to be cancelled in accordance with the Applicable Procedures. 

(d) Reimbursement of Interest upon Conversion. If a Holder converts a Note after the Close of Business on a Regular Record Date,
but prior to the Open of Business on the Interest Payment Date corresponding to such Regular Record Date, then (x) the Holder of such Note at the Close of Business on such Regular Record Date shall be entitled, notwithstanding such conversion,
to receive, on such Interest Payment Date, the unpaid interest that has accrued on such Note to, but excluding, such Interest Payment Date; and (y) the Holder of such Note must, upon surrender of such Note for conversion, accompany such Note
with an amount of cash equal to the amount of interest that will be payable on such Note on such Interest Payment Date; provided, however, that a Holder need not make such payment (A) for conversions following the Regular Record
Date immediately preceding the Maturity Date; (B) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment
Date and  

  
 - 61 - 








 
the Holder converts its Note after the Close of Business on such Regular Record Date and on or prior to the Open of Business on such Interest Payment Date; (C) if the Company has
specified a Redemption Date that is after a Regular Record Date and on or prior to the Business Day immediately following the Interest Payment Date corresponding to such Regular Record Date and such Holder surrenders such Note for conversion after
such Regular Record Date and prior to the Open of Business on such Interest Payment Date; or (D) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Note. 

(e) Taxes and Duties. If a Holder converts a Note, the Company will pay any documentary, stamp or similar issue or transfer tax
due on the issue of any shares of the Common Stock upon the conversion; provided, however, that if any tax is due because the converting Holder requested that shares of Common Stock be issued in a name other than its own, such Holder
will pay such tax and the Conversion Agent, until having received a sum sufficient to pay such tax, may refuse to deliver any certificates representing the shares of Common Stock being issued in a name other than that of such Holder. 

(f) Notices. Whenever a Conversion Date occurs with respect to a Note, the Conversion Agent will, as promptly as possible, and
in no event later than the Business Day immediately following such Conversion Date, deliver to the Company and the Trustee notice that a Conversion Date has occurred, which notice will state such Conversion Date, the principal amount of Notes
converted on such Conversion Date and the names of the Holders that converted Notes on such Conversion Date. 
 Section 10.03
Settlement Upon Conversion. 
 (a) Conversion Obligation. 

(i) Settlement Method. Except as provided in Section 10.07, upon conversion of any Note, if the Company has
not received the requisite approval from its stockholders in accordance with Rule 312.03 of the New York Stock Exchange Listed Company Manual (the “Stockholder Approval”) to issue 20% or more of its Common Stock upon conversion of
the Notes prior to the relevant Conversion Date (or, if earlier, the 45th Scheduled Trading Day immediately preceding the Maturity Date), the Company shall deliver to the converting Holder, in respect of each $1,000 principal amount of Notes being
converted, a number of shares of its Common Stock equal to the Conversion Rate in effect on the Conversion Date, together with a cash payment in lieu of any fractional share of Common Stock issuable upon conversion based on the Daily VWAP on the
relevant Conversion Date. For the avoidance of doubt, any settlement of conversions pursuant to this Section 10.03(a)(i) shall be considered “Physical Settlement” for all purposes hereunder, unless the context otherwise requires

 (ii) The provisions of this Section 10.03(a)(ii), whether or not expressly stated therein, will only apply if the Company has
received Stockholder Approval prior to the relevant Conversion Date (or, if earlier, the 45th Scheduled Trading Day immediately preceding the Maturity Date). 

(A) Except as provided in Section 10.07, upon conversion of any Note, if the Company has received Stockholder
Approval prior to the relevant Conversion Date (or, if 

  
 - 62 - 








 
earlier, the 45th Scheduled Trading Day immediately preceding the Maturity Date), the Company may choose to pay or deliver, as the case may be, to the converting Holder cash in accordance
with Section 10.03(a)(iii)(B) (“Cash Settlement”), shares of Common Stock, together with cash, if applicable, in lieu of any fractional share of Common Stock in accordance with Section 10.03(a)(iii)(A) (“Physical
Settlement”) or a combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of any fractional share of Common Stock in accordance with Section 10.03(a)(iii)(C) (“Combination
Settlement”), at the Company’s election (each of these settlement methods a “Settlement Method”); 

(B) all conversions of Notes whose Conversion Date occurs on or after April 1, 2019 will be settled using the same
Settlement Method, and the Company shall send written notice of such Settlement Method to Holders and the Trustee and Conversion Agent, no later than the Close of Business on the Scheduled Trading Day immediately preceding April 1, 2019; 

(C) the Company shall use the same Settlement Method for all conversions of Notes whose Conversion Dates occur on the same day
(and, for the avoidance of doubt, the Company shall not be obligated to use the same Settlement Method with respect to conversions of Notes whose Conversion Dates occur on different days, except as provided in Clause (B) above); 

(D) if the Company elects a Settlement Method with respect to the conversion of any Note whose Conversion Date occurs before
April 1, 2019, the Company shall send written notice of such Settlement Method to the Holder of such Note,, and the Trustee and Conversion Agent, no later no later than the Close of Business on the Trading Day immediately following such
Conversion Date; 
 (E) if the Company has received Stockholder Approval and does not timely elect a Settlement Method with
respect to the conversion of a Note, then the Company will be deemed to have elected Combination Settlement with a Specified Dollar Amount per $1,000 principal amount of such Note equal to $1,000; and 

(F) if the Company timely elects Combination Settlement with respect to the conversion of a Note but does not timely notify the
Holder of such Note of the Specified Dollar Amount, then the Specified Dollar Amount for such conversion will be deemed to be $1,000 per $1,000 principal amount of such Note. 

(iii) Conversion Consideration. With respect to any conversions after obtaining Stockholder Approval, the type and amount of
consideration (the “Conversion Consideration”) due in respect of each $1,000 principal amount of a Note to be converted shall be as follows: 

(A) if Physical Settlement applies to such conversion, (I) a whole number of shares of Common Stock equal to the
Conversion Rate in effect on the Conversion Date for such conversion (which, if not a whole number, shall be rounded down to the nearest whole number); and (II) if such Conversion Rate is not a whole number, cash in lieu of


  
 - 63 - 








 
the related fractional share in an amount equal to the product of (x) the Daily VWAP on such Conversion Date (or if such Conversion Date is not a Trading Day, the immediately preceding
Trading Day) and (y) the fractional portion of such Conversion Rate; 
 (B) if Cash Settlement applies to such
conversion, cash in an amount equal to the sum of the Daily Conversion Values for each of the 40 consecutive Trading Days in the Observation Period for such conversion; or 

(C) if Combination Settlement applies to such conversion, a settlement amount equal to (I) the sum of the Daily Settlement
Amounts for each of the 40 consecutive Trading Days in the Observation Period for such conversion (which, for the avoidance of doubt, shall consist of a number of whole shares of Common Stock equal to the sum of the Daily Share Amounts for each of
the Trading Days in such Observation Period (which, if such sum is not a whole number, shall be rounded down to the nearest whole number) and cash in an amount equal to the sum of the Daily Cash Amounts for each of the Trading Days in such
Observation Period); and (II) if the sum of the Daily Share Amounts for each of the Trading Days in such Observation Period is not a whole number, cash in lieu of the related fractional share in an amount equal to the product of (x) the Daily
VWAP on the last Trading Day of such Observation Period and (y) the fractional portion of such sum. 
 With respect to any conversion
of Notes to which Cash Settlement or Combination Settlement applies, the Company shall determine the Conversion Consideration due thereupon promptly following the last day of the applicable Observation Period and shall promptly thereafter notify the
Trustee and the Conversion Agent (if other than the Trustee) in writing of the same and the calculation thereof in reasonable detail. Neither the Trustee nor the Conversion Agent (if other than the Trustee) shall have any responsibility for any such
determination. 
 (iv) Delivery of Conversion Consideration. Except as set forth in Sections 10.05, 10.07 and 10.08 hereof,
the Company shall pay or deliver, as the case may be, the Conversion Consideration due upon the conversion of any Note to the Holder thereof as follows: (i) if Cash Settlement or Combination Settlement applies to such conversion, on the third
Business Day immediately following the last Trading Day of the Observation Period for such conversion; and (ii) if Physical Settlement applies to such conversion, on the third Business Day immediately following the Conversion Date for such
conversion. 
 (b) Conversion of Multiple Notes by a Single Holder. If a Holder converts more than one Note on a single
Conversion Date, the Conversion Consideration due in respect of such conversion will be computed based on the total principal amount of Notes converted on such Conversion Date by such Holder. 

(c) Settlement of Accrued Interest and Deemed Payment of Principal. If a Holder converts a Note, the Company will not adjust the
Conversion Rate to account for any accrued and unpaid interest on the Note, and the Company’s delivery of the Conversion Consideration due upon such conversion will be deemed to satisfy and discharge in full the Company’s obligation to pay
the principal of such Note and accrued and unpaid interest, if any, on, such  

  
 - 64 - 








 
Note to, but excluding the Conversion Date; provided, however, that if a Holder converts a Note after a Regular Record Date and prior to the Open of Business on the
corresponding Interest Payment Date, the Company will still be obligated to pay the interest due on such Interest Payment Date to the Holder of such Note as of the Close of Business on such Regular Record Date. As a result, except as otherwise
provided in the proviso to the immediately preceding sentence, any accrued and unpaid interest with respect to a converted Note will be deemed to be paid in full rather than cancelled, extinguished or forfeited. In addition, if both cash and shares
of the Common Stock are delivered upon the conversion of a Note, accrued and unpaid interest will be deemed to be paid first out of the amount of cash so delivered. 

(d) If the Company receives Stockholder Approval on any day, the Company shall so notify Holders, the Trustee and the Conversion Agent
prior to the Close of Business on the fourth Business Day following such day; provided that such notice requirement shall be satisfied if the Company discloses such Stockholder Approval in a Current Report on Form 8-K filed by the Company on
or prior to the fourth Business Day following the day of such Stockholder Approval. 
 Section 10.04 Common Stock Issued Upon
Conversion. 
 (a) Prior to issuing of any shares of Common Stock under this Article 10, and from time to time thereafter as may be
necessary, the Company will reserve out of its authorized but unissued shares of Common Stock a number of shares of Common Stock sufficient to permit the conversion of all then-outstanding Notes under Physical Settlement. 

(b) Any shares of Common Stock delivered upon the conversion of the Notes will be newly issued shares or treasury shares, duly and
validly issued, fully paid, nonassessable, free from preemptive rights and free of any lien or adverse claim (except to the extent of any lien or adverse claim created by the action or inaction of the Holder or other Person to whom such shares of
Common Stock will be delivered). In addition, the Company will endeavor to comply promptly with all federal and state securities laws regulating the offer and delivery of any shares of Common Stock issuable upon conversion of the Notes;
provided that the Company will not be obligated to register the offer and sale of such Common Stock under the Securities Act or any other applicable securities laws. The Company will also use commercially reasonable efforts to cause any
shares of Common Stock issuable upon conversion of a Note to be listed on whatever stock exchange(s) the Common Stock is listed on the date the converting Holder becomes a record holder of such Common Stock. 

(c) If any shares of the Common Stock issued upon conversion will, upon delivery as part of the conversion obligation, be “restricted
securities” (within the meaning of Rule 144 or any successor provision in effect at such time), such shares of Common Stock (i) will be issued in physical, certificated form; (ii) will not be held in book-entry form through the
facilities of the Depositary; and (iii) will bear any restrictive legends the Company or the Transfer Agent deem necessary to comply with applicable law. 

Section 10.05 Adjustment of Conversion Rate. The Company will adjust the Conversion Rate from time to time as described in this
Section 10.05, except that the Company will not make an adjustment to the Conversion Rate if each Holder participates (other than in a share split or 

  
 - 65 - 








 
share combination), at the same time and upon the same terms as holders of the Common Stock, and solely as a result of holding the Notes, in the relevant transaction described in this
Section 10.05 without having to convert its Notes and as if it held number of shares of the Common Stock equal to the product of (i) the Conversion Rate in effect on the applicable record date, Effective Date or expiration date, and
(ii) the aggregate principal amount of Notes held by such Holder (express in thousands) on such date, rounded up to the nearest whole number. 

(a) Stock Dividends and Share Splits. If the Company exclusively issues to all or substantially all holders of the Common Stock
shares of Common Stock as a dividend or distribution on shares of the outstanding Common Stock, or if the Company effects a share split of the Common Stock or a share combination of the Common Stock, the Conversion Rate will be adjusted based on the
following formula: 
  
 



 
 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 the Open of Business on such Effective Date, as the case may be;
			
	OS0	  	=	 	the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date or Effective Date, as the case may be; and
			
	OS1	  	=	 	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination.

 If any dividend, distribution, share split or share combination of the type described in this Section 10.05(a) is
declared, but not so paid or made, the Conversion Rate will be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution or to effect such share split or share combination, to the
Conversion Rate that would then be in effect if such dividend, distribution, share split or share combination had not been declared or announced. 

  
 - 66 - 








 (b) Rights, Options and Warrants. If the Company issues, to all or substantially
all holders of its outstanding Common Stock, rights, options or warrants entitling such holders, for a period of not more than 60 calendar days after the record date of such issuance, to subscribe for, or purchase, shares of 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, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion
Rate will be increased based on the following formula: 
  
 



 
 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, options or warrants; and
			
	Y	  	=	  	the number of shares of Common Stock equal to the quotient of (i) the aggregate price payable to exercise such rights, options or warrants, over (ii) the average of the Last Reported Sale Prices of the Common Stock over the 10
consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

 To the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants,
including because the issued rights, options or warrants were not exercised, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants
been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect if
the Ex-Dividend Date for such issuance had not occurred. 
 For purposes of this Section 10.05(b), in determining whether any rights,
options or warrants entitle holders of the Common Stock to subscribe for, or purchase, shares of Common Stock at a price per share less than the average of the Last Reported Sale Prices of Common Stock for the 10 consecutive Trading Day period
ending on, and including, the Trading Day immediately preceding the date of announcement for an issuance, and in determining the aggregate price payable to exercise such rights, options or warrants, there will be taken into account any consideration
received by the Company for such rights, options or warrants and any amount payable on exercise thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. 

(c) Spin-Offs and Other Distributed Property. 

  
 - 67 - 








 (i) If the Company distributes shares of its Capital Stock, evidences of its indebtedness or
other assets or property of the Company, or rights, options or warrants to acquire Capital Stock of the Company or other securities, to all or substantially all holders of the Common Stock, excluding: 

(A) dividends, distributions, rights, options or warrants for which an adjustment was effected pursuant to
Section 10.05(a) hereof or Section 10.05(b) hereof, as applicable; 
 (B) dividends or distributions paid
exclusively in cash for which an adjustment was effected pursuant to Section 10.05(d) hereof; and 
 (C) Spin-Offs for
which the provisions set forth in Section 10.05(c)(ii) hereof will apply, 
 then the Conversion Rate will be increased based on the following formula:

  
 



 
 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, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and
			
	FMV	  	=	  	the fair market value (as determined by the Company’s Board of Directors) of the shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants distributed with respect to each outstanding
share of Common Stock on the Ex-Dividend Date for such distribution.

 Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than the “SP0” (as defined above), in lieu of the foregoing increase, each Holder will receive, for each $1,000 principal amount of Notes held on the record date for the distribution, at the same time and
upon the same terms as holders of the Common Stock, the amount and kind of shares of Capital Stock, evidences of indebtedness, assets or property, rights, options or warrants or other securities that such Holder would have received if such Holder
had owned a number of shares of Common Stock equal to the Conversion Rate in effect on the record date for such distribution. 

  
 - 68 - 








 If any distribution of the type described in this Section 10.05(c)(i) is not so paid or
made, or if any rights, options or warrants are not exercised before their expiration date, the Conversion Rate will be readjusted to be the Conversion Rate that would then be in effect if such distribution had not been declared. 

(ii) With respect to an adjustment pursuant to this Section 10.05(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 an Affiliate, a Subsidiary or other business unit of the Company, and such Capital Stock or similar equity interest is
listed or quoted (or will be listed or quoted upon the consummation of the transaction) on a national securities exchange or a reasonably comparable non-U.S. equivalent (a “Spin-Off”), the Conversion Rate will be increased based on
the following formula: 
  
 



 
 where 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such Spin-Off;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;
			
	FMV0	  	=	  	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the 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 the Common Stock over the Valuation Period.

 The adjustment to the Conversion Rate under this Section 10.05(c)(ii) will be calculated as of the Close
of Business on the last Trading Day of the Valuation Period but will be given effect as of immediately after the Open of Business on the Ex-Dividend Date of the Spin-Off, provided, that (i) if the Company has not obtained Stockholder Approval,
the Company shall delay the settlement of any conversion of Notes where the Conversion Date occurs during the Valuation Period until the third Business Day after the last day of the Valuation Period or (ii) if the Company has obtained
Stockholder Approval, the Company shall delay the settlement of any conversion of Notes where the Conversion Date (in the case of Physical Settlement) or any Trading Day of the applicable Observation Period (in the case of Cash Settlement or
Combination Settlement) occurs during the Valuation Period until the third Business Day after the last day of the Valuation Period. If any distribution of the type described in this Section 10.05(c)(ii) is declared but not so made, the
Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to make such distribution, to the Conversion Rate that would then be in effect if such distribution had not been declared. 

  
 - 69 - 








 For the purposes of this Section 10.05(c) and subsections (a) and (b) of this
Section 10.05, any dividend or distribution to which this Section 10.05(c) applies and which dividend or distribution also includes one or both of: 

(A) a dividend or distribution of shares of Common Stock to which Section 10.05(a) hereof applies (a
“Clause A Distribution”); or 
 (B) a dividend or distribution of rights, options or warrants
to which Section 10.05(b) hereof applies (a “Clause B Distribution”) 
 (any such distribution, a “Multi-Clause
Distribution”), then (i) the portion of such Multi-Clause Distribution that is not a Clause A Distribution or a Clause B Distribution will be deemed to be a dividend or distribution to which this Section 10.05(c) applies (a
“Clause C Distribution”), and any Conversion Rate adjustment required by this Section 10.05(c) with respect to such Clause C Distribution will be made without considering any shares of Common Stock, if any, issuable as part of
the portion of such Multi-Clause Distribution that is a Clause A Distribution or a Clause B Distribution, as applicable, (ii) the portion of such Multi-Clause Distribution that is a Clause B Distribution, if any, will be deemed to be
distributed immediately following the Clause C Distribution, and any Conversion Rate adjustment required by Section 10.05(b) hereof with respect to such Clause B Distribution will be made, with any shares of Common Stock issuable as part of the
portion of such Multi-Clause Distribution that is a Clause C Distribution deemed to be “outstanding immediately prior to the Open of Business on such Ex-Dividend Date” for the purposes of making such adjustment and (iii) the portion
of such Multi-Clause Distribution that is a Clause A Distribution, if any, will be deemed to be distributed immediately following the Clause B Distribution or Clause C Distribution, as the case may be, and any Conversion Rate adjustment required by
Section 10.05(a) hereof with respect to such Clause A Distribution will be made, with any shares of Common Stock issuable as part of the portion of such Multi-Clause Distribution that is either a Clause C Distribution or a Clause B Distribution
deemed to be “outstanding immediately prior to the Open of Business on such Ex-Dividend Date or Effective Date” for the purposes of making such adjustment. 

(d) Cash Dividends or Distributions. If any cash dividend or distribution (other than a distribution as to which an adjustment
to the Conversion Rate was effected pursuant to Section 10.05(e)) is made to all or substantially all holders of the Common Stock, the Conversion Rate will be increased based on the following formula: 

 
 



 
 where 
  

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


  
 - 70 - 









					
			
	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 Common Stock.

 Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder will receive, for each $1,000 principal amount of Notes held on the record date for such cash dividend or distribution, at
the same time and upon the same terms as holders of the Common Stock, the amount of cash that such Holder would have received if such Holder had owned a number of shares of Common Stock equal to the Conversion Rate in effect on such record date. If
any dividend or distribution of the type described in this Section 10.05(d) is declared but not so paid or made, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not
been declared. 
 (e) Tender Offers or Exchange Offers. If the Company or any Subsidiary makes a payment in respect of a
tender offer or exchange offer for the 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 of the Common Stock on the Trading Day next
succeeding the last date on which tenders or exchanges may be made pursuant to such tender offer or exchange offer (as it may be amended), the Conversion Rate will be increased based on the following formula: 

 
 



 
 where 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Expiration Time;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Expiration Time;
			
	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 time (the “Expiration Time”) on the date such tender or exchange offer expires (prior to giving effect to the purchase of all shares accepted
for purchase or exchange in such tender or exchange offer);


  
 - 71 - 









					
			
	OS1	  	=	  	the number of shares of Common Stock outstanding immediately after the Expiration Time (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 (the “Averaging Period”) commencing on the Trading Day next succeeding the date such tender or exchange
offer expires.

 The adjustment to the Conversion Rate pursuant to this Section 10.05(e) will be calculated as of the
Close of Business on the last Trading Day of the Averaging Period but will be given effect as of immediately after the Expiration Time, provided that (i) if the Company has not obtained Stockholder Approval, the Company will delay the
settlement of any conversion of Notes where the Conversion Date occurs during the Averaging Period until the third Business Day after the last day of the Averaging Period or (ii) if the Company has obtained Stockholder Approval, the Company
shall delay the settlement of any conversion of Notes where the Conversion Date (in the case of Physical Settlement) or any Trading Day of the applicable Observation Period (in the case of Cash Settlement or Combination Settlement) occurs during the
Averaging Period until the third Business Day after the last day of the Averaging Period. 
 (f) Successive Adjustments. After
an adjustment to the Conversion Rate under this Article 10, any subsequent event requiring an adjustment under this Article 10 will cause an adjustment to the Conversion Rate as so adjusted, without duplication. 

(g) Adjustments Not Yet Effective. If a Holder converts a Note and, as of the Conversion Date for such Note, any distribution or
transaction that requires an adjustment to the Conversion Rate pursuant to Sections 10.05(a) through (e) hereof has occurred but has not yet resulted in an adjustment to the Conversion Rate and the shares of Common Stock, if any, that such
Holder will receive upon settlement of its converted Note are not entitled to participate in the relevant distribution or transaction (because they were not held on a related record date or otherwise), then the Company will adjust the number of
shares of Common Stock that it delivers to such Holder to reflect the relevant distribution or transaction. 
 (h)
Conversion Rate Adjustments where Converting Holders Participate in the Relevant Dividend, Distribution or other Transaction. Notwithstanding anything to the contrary herein or in the Notes, if a Conversion Rate adjustment becomes effective
on any Ex-Dividend Date pursuant to Section 10.05, 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, on such record date, as the record holder of the shares
of Common Stock, if any, issuable upon such conversion based on an adjusted Conversion Rate for such Ex-Dividend Date, then the Conversion Rate adjustment relating to such Ex-Dividend Date will not be made for such converting holder. Instead, such
Holder will be treated as if such Holder were, as of such record date, the record owner of such shares of Common Stock on an unadjusted basis and will participate in the related dividend, distribution or other event giving rise to such adjustment.
 

  
 - 72 - 








 (i) Special Settlement Provisions. Notwithstanding anything to the contrary herein,
if the Company obtains Stockholder Approval and if a Holder converts a Note and: 
 (i) Combination Settlement is applicable to such
Note; 
 (ii) the Record Date, Effective Date or Expiration Date for any event that requires adjustment to the Conversion Rate pursuant to
Sections 10.05(a) through (e) occurs: 
 (A) on or after the first Trading Day of the applicable Observation Period; and

 (B) on or prior to the last Trading Day of such Observation Period; and 

(iii) the Daily Settlement Amount for any Trading Day in such Observation Period that occurs on or prior to such Record Date, Effective Date
or Expiration Date: 
 (A) includes shares of Common Stock that do not entitle their Holder to participate in such event; and

 (B) is calculated based on a Conversion Rate that is not adjusted on account of such event; 

then, on account of such conversion, the Company will, on such Record Date, Effective Date or Expiration Date, treat such Holder, as having converted such
Notes, as though it were the Record Holder of a number of shares of Common Stock equal to the total number of shares of Common Stock that: 

(i) are deliverable as part of the Daily Settlement Amount; 

(A) for a Trading Day in such Observation Period that occurs on or prior to such Record Date, Effective Date or Expiration
Date; and 
 (B) is calculated based on a Conversion Rate that is not adjusted for such event; and 

(ii) if not for this Section 10.05(i), would not entitle such Holder to participate in such event. 

(j) Shareholder Rights Plans. If the Company has a rights plan in effect when a Holder converts a Note, the Company will deliver
to such Holder, to the extent, if at all, such Holder receives any shares of Common Stock upon such conversion of such Note, any rights that, under the rights plan, would be applicable to a share of Common Stock, unless prior to the Conversion Date
for such Note, the rights have separated from the Common Stock, in which case, and only in such case, the Conversion Rate will be adjusted pursuant to Section 10.05(c)(i) as if, at the time of such separation, the Company had distributed to all
holders of the Common Stock shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire its Capital Stock, subject to readjustment in the event of the expiration,
termination or redemption of such rights. 
 (k) Other Adjustments. Whenever any provision of this Indenture requires
the calculation of the Last Reported Sale Price or a function thereof over a period of multiple days (including any Observation Period and the Stock Price for purposes of a Make-Whole  

  
 - 73 - 








 
Fundamental Change), the Company will make appropriate adjustments to the Last Reported Sale Price or such function thereof 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, Effective Date or expiration date of the event occurs, at any time during such period. 

(l) Restrictions on Adjustments. Except as a result of a reverse share split or share combination subject to
Section 10.05(a), and except for readjustments pursuant to the last paragraph of Section 10.05(a), readjustments pursuant to the penultimate paragraph of Section 10.05(b), readjustments pursuant to the last paragraph of
Section 10.05(c)(i), readjustments pursuant to the penultimate paragraph of Section 10.05(c)(ii) and readjustments pursuant to the last paragraph of Section 10.05(d), in no event will the Conversion Rate be adjusted downward pursuant
to Sections 10.05(a), (b), (c), (d) or (e) hereof. 
 In addition, notwithstanding anything to the contrary elsewhere in this
Indenture, the Conversion Rate will not be adjusted: 
 (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 the preceding clause and outstanding as of the date of the Issue Date; 

(iv) upon the repurchase of any shares of Common Stock pursuant to an open-market share repurchase program or other buy-back transaction that
is not a tender offer or exchange offer subject to Section 10.05(e). 
 (v) for a change in the par value of the Common Stock; or 

(vi) for accrued and unpaid interest. 

(m) Deferral of Adjustments. The Company may defer any adjustment to the Conversion Rate unless such adjustment would increase
or decrease the Conversion Rate by at least 1% of the Conversion Rate in effect at the time the Company would otherwise be required to make such adjustment; provided, however, that if the Company defers an adjustment pursuant to this
Section 10.05(m), then the Company must carry forward such adjustment and take it into account in any future adjustment. Notwithstanding the foregoing, (i) on each Conversion Date (in the case of Physical Settlement) or on each Trading Day
of any Observation Period (in the case of Cash Settlement or Combination Settlement), (ii) on the occurrence of any Fundamental Change or Make-Whole Fundamental Change and (iii) on every one-year anniversary of the Issue Date, the Company
will give effect to all Conversion Rate adjustments that have otherwise been deferred pursuant to this Section 10.05(m), and such adjustments will no longer be carried forward and taken into account in any future adjustment.

 (n) Miscellaneous. 

(i) Certain Definitions. 

(I) For purposes of this Section 10.05, (1) the number of shares outstanding at any time will include shares issuable in respect of
scrip certificates issued in lieu of fractions of shares of Common Stock, but, (2) 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, will not include shares
of Common Stock held in the treasury of the Company. 
 (II) For purposes of this Section 10.05, the term “Effective
Date” will mean the first date on which the Common Stock trades on the applicable exchange or in the applicable market, regular way, reflecting the relevant share split or share combination, as applicable. 

(III) For purposes of this Article 10, the term “Ex-Dividend Date” will mean the first date on which the shares of
the Common Stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive the issuance, dividend or distribution in question. 

(ii) Notices. Upon the public announcement of any event that will require the Company to make an adjustment to the Conversion Rate
pursuant to this Section 10.05, the Company will deliver to each Holder a written notice, which notice will include (i) a brief description of such event, (ii) the date on which the Company anticipates that such event will occur,
(iii) the date on which the Company anticipates that the adjustment to the Conversion Rate will become effective, and (iv) if any record date, expiration date, Ex-Dividend Date or Effective Date is applicable to such event, such record
date, expiration date, Ex-Dividend Date or Effective Date. Neither the failure to give such notice, nor any defect therein, will affect the legality or validity of such action by the Company. 

Whenever the Company adjusts the Conversion Rate pursuant to this Section 10.05, the Company will promptly deliver to each Holder a
written notice, which notice will include (i) a brief description of the event requiring adjustment to the Conversion Rate pursuant to this Section 10.05, (ii) the effective time of such adjustment, (iii) the Conversion Rate in
effect immediately after such adjustment is made and (iv) a schedule explaining, in reasonable detail, how the Company calculated such adjustment. On the same day the Company delivers such notice to each Holder, the Company will deliver to the
Trustee, the Paying Agent and the Conversion Agent an Officers’ Certificate that includes all of the information contained in such notice, which Officers’ Certificate each of the Trustee, the Paying Agent and the Conversion Agent may treat
as conclusive evidence that the adjustment specified in such Officers’ Certificate is correct and will be in effect as of the effective time specified in such Officers’ Certificate. The failure to deliver such notice will not affect the
legality or validity of any such adjustment. 

  
 - 75 - 








 (iii) All calculations and other determinations in respect of the Conversion Rate shall be made
by the Company to the nearest 1/10000th of a share, with five-one-hundred-thousandths rounded upward. 
 Section 10.06 Voluntary
Adjustments. 
 (a) Best Interest Increases. The Company may, from time to time, to the extent permitted by law and the
rules of the New York Stock Exchange or any other securities exchange on which the Common Stock is then listed, increase the Conversion Rate by any amount if (i) the Board of Directors determines that such increase is in the best interest of
the Company, (ii) such increase is in effect for a period of at least 20 Business Days, and (iii) during such period, such increase is irrevocable. 

(b) Tax-Related Increases. The Company may (but is not required to) increase the Conversion Rate if the Board of Directors
determines that such increase is advisable to avoid, or diminish, any income tax imposed on holders of the Common Stock or rights to purchase the Common Stock as a result of any dividend or distribution of shares (or rights to acquire shares) or
similar event treated as such for U.S. federal income tax purposes. 
 (c) Notices. Whenever the Board of Directors determines
that the Company will increase the Conversion Rate pursuant to this Section 10.06, the Company will mail to the Trustee, Conversion Agent and to each Holder notice of such increase at least 15 Business Days before such increase will take
effect, which notice will state the increase to be made and the period during which such increase will be in effect. 
 Section 10.07
Adjustments Upon Certain Fundamental Changes. 
 (a) General. If (i) a Fundamental Change
(determined after giving effect to the paragraph immediately following clause (d) of the definition thereof, but without regard to the exclusion in clause (b)(ii) of the definition thereof) occurs or (ii) the Company calls the Notes for
redemption pursuant to Article 11 (either such event, a “Make-Whole Fundamental Change”), and a Holder converts its Notes in connection with such Make-Whole Fundamental Change, the Company will, in the circumstances described in
this Section 10.07, increase the Conversion Rate for such Notes by the number of additional shares of Common Stock (the “Additional Shares”) set forth in this Section 10.07. For purposes of this Section 10.07, a
conversion of Notes will be deemed to be “in connection with”: 
 (i) a Make-Whole Fundamental Change described in clause
(i) of the definition of “Make-Whole Fundamental Change” if (A) for Conversion Dates prior to April 1, 2019, the applicable Conversion Date occurs during the period when the Notes are convertible on account of such
Make-Whole Fundamental Change pursuant to Section 10.01(b)(iii)(B) and (B) for Conversion Dates on or after April 1, 2019 if the applicable Conversion Date occurs during the period 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 Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the
exclusion in clause (b)(ii) of the definition thereof, the 35th Trading Day immediately following the effective date of such Make-Whole Fundamental Change). 

  
 - 76 - 








 (ii) a Make-Whole Fundamental Change described in clause (ii) of the definition of
“Make-Whole Fundamental Change” if the Conversion Notice for such Notes is received by the Conversion Agent during the period beginning on, and including, the Redemption Notice Date and ending on the Close of Business on the Business Day
immediately preceding the Redemption Date. 
 No later than one Business Day immediately after the effective date of a Make-Whole
Fundamental Change described in clause (i) of the definition of Make-Whole Fundamental Change contained in this Section 10.07, the Company will notify the Holders (with a copy to the Trustee and the Conversion Agent) of such effective date
and issue a press release announcing such effective date. 
 (b) Determination of Additional Shares. The number
of Additional Shares by which the Conversion Rate will be increased if a Holder converts a Note in connection with a Make-Whole Fundamental Change will be determined by reference to the table below, and will be based on the Make-Whole Fundamental
Change Effective Date and the Stock Price for such Make-Whole Fundamental Change. For any Make-Whole Fundamental Change, the “Make-Whole Fundamental Change Effective Date” will mean, (i) if such Make-Whole Fundamental Change is
of the type described in clause (i) of the definition of Make-Whole Fundamental Change contained in Section 10.07(a) hereof, the date on which such Make-Whole Fundamental Change occurs or becomes effective, and (ii) if such Make-Whole
Fundamental Change is of the type described in clause (ii) of the definition of Make-Whole Fundamental Change contained in Section 10.07(a) hereof, the applicable Redemption Notice Date. 

(c) Adjustment of Stock Prices and Additional Shares. The Stock Prices set forth in the first row (i.e., the column
headers) of the table below will be adjusted on each date on which the Conversion Rate must be adjusted pursuant to Section 10.05. The adjusted Stock Prices will equal the Stock Prices in effect immediately prior to such adjustment, multiplied
by a fraction, (i) the numerator of which is the Conversion Rate in effect immediately prior to the adjustment giving rise to the share price adjustment, and (ii) the denominator of which is the Conversion Rate in effect immediately after
the adjustment. The numbers of Additional Shares set forth in the table below will be adjusted in the same manner, at the same time and for the same events for which the Conversion Rate is adjusted pursuant to Section 10.05 hereof. 

(d) Additional Shares Table. The following table sets forth hypothetical Make-Whole Fundamental Change Effective Dates, Stock
Prices and the number of Additional Shares by which the Conversion Rate will be increased per $1,000 principal amount of Notes for a Holder that converts a Note in connection with a Make-Whole Fundamental Change having such Make-Whole Fundamental
Change Effective Date and Stock Price.

 (e) Use of Additional Shares Table. If the Stock Price and/or Make-Whole
Fundamental Change Effective Date for a Make-Whole Fundamental Change are not set forth in the table above, then: 

(A) if the Stock Price is between two Stock Prices in the table or the Make-Whole Fundamental Change Effective Date is between
two Make-Whole Fundamental Change Effective Dates in the table, the number of Additional Shares by which the Conversion Rate will be increased for a Holder that converts a Note in connection with such Make-Whole Fundamental Change will be determined
by a straight-line interpolation between the numbers of Additional Shares set forth for the higher and lower Stock Prices listed in the table and the earlier and later Make-Whole Fundamental Change Effective Dates listed in the table, as applicable,
based on a 365- or 366-day year, as applicable; 
 (B) if the Stock Price is greater than $20.00, subject to adjustment in
the same manner as the Stock Prices set forth in the column headings of the table, no Additional Shares will be added to the Conversion Rate; and 

(C) if the Stock Price is less than $4.41 per share, subject to adjustment in the same manner as the Stock Prices set forth in
the column headings of the table, no Additional Shares will be added to the Conversion Rate. 
 Notwithstanding the foregoing, in no event will the
Conversion Rate be increased as a result of this Section 10.07 to exceed 226.7573 shares of Common Stock per $1,000 principal amount of Notes, subject to adjustment in the same manner, at the same time and for the same events for which the
Conversion Rate must be adjusted as set forth in Section 10.05 hereof. 
 (f) Settlement or Conversion. If a Holder
converts a Note in connection with a Make-Whole Fundamental Change, the Company will settle such conversion by delivering Conversion Consideration in accordance with Section 10.03 hereof; provided, however, that notwithstanding
anything to the contrary in Section 10.03 hereof, if a Holder converts a Note in connection with a Make-Whole Fundamental Change described in clause (b)(ii) of the definition of Fundamental Change in which the holders of the Common Stock
receive only cash in consideration for their shares of Common Stock, the Company will settle such conversion by delivering to such Holder, on the third Business Day immediately following the Conversion Date for such Note, an amount of cash, for each
$1,000 principal amount of such Note converted, equal to the product of (i) the Conversion Rate on the Conversion Date applicable to such Note (including any Additional Shares added to such Conversion Rate pursuant to this Section 10.07)
and (ii) the Stock Price for such Make-Whole Fundamental Change. 
 Section 10.08 Effect of Recapitalization,
Reclassification, Consolidation, Merger or Sale. 

  
 - 78 - 








 (a) General. If any of the following events occur: 

 

	 	(1)	any recapitalization, reclassification or change of Common Stock (other than changes in par value or to no par value or resulting from a subdivision or combination); 


 

	 	(2)	any consolidation, merger, combination or similar transaction involving the Company; 

  

	 	(3)	any sale, lease or other transfer to a third party of substantially all of the consolidated assets of the Company and its Subsidiaries substantially as an entirety; or 


 

	 	(4)	any statutory share exchange, 

 and, in each case, as a result of which the Common Stock would be
converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “Share Exchange Event” and any such stock, other securities or other property or
assets, “Reference Property,” and the amount of Reference Property that a holder of one share of Common Stock immediately prior to such Share Exchange Event would have been entitled to receive upon the occurrence of such Share
Exchange Event, “Unit of Reference Property”), then the Company or the successor or purchasing company, as the case may be, shall execute with the Trustee a supplemental indenture providing that, at and after the effective time of
such transaction, the Notes will become convertible into Reference Property. However, at and after the effective time of such Share Exchange Event, (i) if the Company has not obtained Stockholder Approval prior to the relevant Conversion Date
(or, if earlier, the 45th Scheduled Trading Day immediately preceding the Maturity Date), for each share of Common Stock that the Company would otherwise be obligated to deliver with respect to such conversion, the Company will instead deliver a
Unit of Reference Property and (ii) if the Company has obtained Stockholder Approval prior to the relevant Conversion Date (or, if earlier, the 45th Scheduled Trading Day immediately preceding the Maturity Date), the amount of cash (if any) and
the number of Units of Reference Property (if any) that the Company will deliver will be determined in accordance with Section 10.03(a)(iii) (and the definitions contained therein), except that for any Trading Day during the relevant
Observation Period in the case of Cash Settlement or Combination Settlement, (a) the Daily VWAP for such Trading Day shall be calculated based on the value of a Unit of Reference Property on such Trading Day; and (b) for each share of
Common Stock that the Company would otherwise be obligated to deliver on such Trading Day, will instead deliver a Unit of Reference Property. 

If a Share Exchange Event causes the Common Stock to be 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 (i) the Reference Property shall be deemed to be (a) the weighted average of the types and amounts of consideration received by the holders of Common
Stock that affirmatively make such an election or (b) if no holders of the Common Stock affirmatively make such an election, the types and amounts of consideration actually received by the holders of the Common Stock, and (ii) the Unit of
Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. The Company shall notify Holders, the Trustee and the Conversion Agent
(if other than the Trustee) of such weighted average (if applicable) as soon as practicable after such determination is made. 

  
 - 79 - 








 Such supplemental indenture described in the second immediately preceding paragraph shall provide
(i) to the extent the Reference Property is comprised, in whole or in part, of Common Equity securities, for anti-dilution and other adjustments that are as nearly equivalent as possible to the adjustments provided for in this Article 10 and
(ii) with respect to any Reference Property other than Common Equity securities and cash, such anti-dilution adjustments (if any) that the Company reasonably considers appropriate in its good faith determination. If the Reference Property in
respect of any Share Exchange Event includes shares of stock, securities or other property or assets of a Person other than the Company or the successor or purchasing company, as the case may be, in such Share Exchange Event, then such supplemental
indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes, including the right of Holders to require the Company to purchase their Notes upon a Fundamental
Change pursuant to Article 3, as the Company shall reasonably consider necessary by reason of the foregoing. 
 If the Company executes a
supplemental indenture pursuant to this Section 10.08, as promptly as practicable, the Company shall file with the Trustee an Officer’s Certificate briefly describing such Share Exchange Event, the composition of a Unit of Reference
Property for such Share Exchange Event, any adjustment to be made with respect thereto and that all conditions precedent to such Share Exchange Event under this Indenture have been complied with. Any failure to deliver such Officer’s
Certificate shall not affect the legality or validity of such supplemental indenture. 
 None of the foregoing provisions shall affect the
right of a Holder to convert its Notes as set forth in Section 10.01 and Section 10.02 prior to the effective date of such Share Exchange Event. 

(b) Notices. 
 (i) As
soon as practicable upon learning the anticipated or actual effective date of any Share Exchange Event, the Company will deliver written notice of such Share Exchange Event to each Holder and the Trustee and Conversion Agent, if not the Trustee.
Such Notice will include: 
 (A) a brief description of such Share Exchange Event; 

(B) the Conversion Rate in effect on the date the Company delivers such notice; 

(C) the anticipated effective date for the Share Exchange Event; 

(D) that, on and after the effective date for the Share Exchange Event, the Notes will be convertible into Reference Property
Units and cash in lieu of fractional Reference Property Units; and 

  
 - 80 - 








 (E) the composition of the Reference Property Unit for such Share Exchange Event.

 (ii) As promptly as practicable after executing a supplemental indenture in accordance with Section 10.08(a) hereof, the Company
will: 
 (A) file with the Trustee an Officers’ Certificate briefly describing the reasons therefor, the composition of
the Reference Property Unit for such Share Exchange Event, any adjustment to be made with respect thereto and that all conditions precedent under this Indenture to such Share Exchange Event have been complied with; and 

(B) cause to be sent to each Holder a notice of the execution of such supplemental indenture and the composition of the
Reference Property Unit for such Share Exchange Event; provided, that the failure to deliver such notice to any Holder will not affect the validity or legality of such supplemental indenture. 

(c) Successive Share Exchange Events. If more than one Share Exchange Event occurs, this Section 10.08 will apply
successively to each Share Exchange Event. 
 (d) Compliance Covenant. The Company will not become a party to any Share
Exchange Event unless its terms are consistent with this Section 10.08. 
 Section 10.09 No Responsibility of Trustee or
Conversion Agent. The Trustee and the Conversion Agent will not have any duty or responsibility to any Holder to determine whether any facts exist that require an adjustment of the Conversion Rate, or with respect to the nature or extent or
calculation of any such adjustment when made, or with respect to the method employed in making the same. Neither the Trustee nor the Conversion Agent will be responsible for any failure of the Company to deliver the Conversion Consideration due 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 10. Without limiting the generality of the foregoing, neither the Trustee nor the
Conversion Agent will be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 10.08 hereof, including with respect to the calculation of the amount of
Conversion Consideration receivable by Holders upon the conversion of their Notes after any Share Exchange Event, and each, subject to the provisions of Article 7, may accept as conclusive evidence of the correctness of any such provisions, and will
be protected in relying upon, the Officers’ Certificate (which the Company will be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. The Conversion Agent (if other than the
Company or an Affiliate of the Company) shall have the same protection under this Section 10.09 as the Trustee. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by
Section 10.01(b) has occurred that makes the Notes eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent written notice thereof with respect to the commencement or
termination of such conversion rights, on which notices the Trustee and the Conversion Agent may conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent as soon as reasonably practicable after the
occurrence of any such event or at such other times as shall be provided for in Section 10.01(b), or in the case of Section 10.01(b)(i), after the Company has actual knowledge thereof.

 ARTICLE 11 

REDEMPTION AT THE OPTION OF THE COMPANY 

Section 11.01 No Sinking Fund. No sinking fund is provided for the Notes. 

Section 11.02 Right To Redeem the Notes. 

(a) General. Prior to October 1, 2017, the Company may not redeem the Notes. On or after October 1,
2017, and prior to the Maturity Date, the Company may redeem (a “Redemption”) all, but not less than all, of the Notes on the Redemption Date for an amount of cash equal to the Redemption Price for such Redemption Date if the Last
Reported Sale Price of the Common Stock equals or exceeds 130% of the Conversion Price in effect on each of at least 20 Trading Days during the 30 consecutive Trading Day period ending on the Trading Day immediately preceding the date on which the
Company delivers the Redemption Notice for such redemption pursuant to Section 11.03 hereof. 
 (b) The
“Redemption Price” means, for any Notes to be redeemed on a Redemption Date, a price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, on such Notes to, but excluding, such
Redemption Date; provided, however, that if a Redemption Date occurs after a Regular Record Date, but on or prior to the Interest Payment Date corresponding to such Regular Record Date, the Redemption Price
for any Notes to be redeemed will equal 100% of the principal amount of such Notes, and accrued and unpaid interest, if any, on such Notes to, but excluding, such Interest Payment Date will be payable, on such Interest Payment Date, to the Holder of
such Notes at the Close of Business on such Regular Record Date. 
 (c) The “Redemption Date” means, for any
redemption, the date specified as such on the Redemption Notice for such redemption, which date must be a Business Day and must be not less than 45 Scheduled Trading Days, nor more than 60 Scheduled Trading Days, immediately following the date on
which the Company delivers such Redemption Notice. 
 Section 11.03 Redemption Notice. At least 45
Scheduled Trading Days but not more than 60 Scheduled Trading Days prior to any Redemption Date, the Company will send to each Holder (with a copy to the Trustee) a written notice of redemption (the “Redemption Notice,” and the date
of such sending, the “Redemption Notice Date”) and, substantially contemporaneously therewith, the Company will issue a press release announcing such redemption. 

For any redemption, the Redemption Notice corresponding to such redemption will specify: 

(A) briefly, a description of the Company’s redemption right under this Indenture; 

  
 - 82 - 








 (B) the Redemption Price for such Redemption Date (for each $1,000 principal
amount of Notes); 
 (C) the Redemption Date for such redemption; 

(D) the name and address of the Paying Agent and of the Conversion Agent; 

(E) that Notes called for redemption may be converted at any time before the Close of Business on the Business Day immediately
preceding the Redemption Date; 
 (F) the Conversion Rate in effect on the Redemption Notice Date for such redemption and the
Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Redemption Notice Date; 
 (G) any
Additional Shares by which the Conversion Rate will be increased pursuant to Section 10.07 hereof for a Holder that converts a Note “in connection with” the Company’s election to redeem the Notes; 

(H) that Notes must be surrendered to the Paying Agent on or before the Redemption Date to collect the Redemption Price; 

(I) that, unless the Company defaults in paying the Redemption Price on the Redemption Date, interest, if any, on a Note will
cease to accrue on and after the Redemption Date; and 
 (J) the CUSIP and ISIN number(s) of the Notes. 

On any Redemption Notice Date, the Company will also furnish to the Trustee an Officers’ Certificate, which Officers’ Certificate
will set forth the aggregate principal amount of Notes then outstanding and include a copy of the Redemption Notice delivered by the Company on such Redemption Notice Date. 

Section 11.04 Effect of Redemption Notice. After the Company has delivered a Redemption Notice, each Holder will have the
right to receive payment of the Redemption Price for its Notes on the later of (i) the Redemption Date and (ii)(a) if the Notes are Definitive Notes, delivery of its Notes to the Paying Agent or (b) if the Notes are Global Notes,
compliance with the Applicable Procedures relating to the redemption and delivery of the beneficial interests to be redeemed to the Paying Agent; provided, however, that, until the Close of Business on the second Business Day
immediately preceding such Redemption Date, Holders may convert their Notes, regardless of whether they have been delivered to the Paying Agent for redemption, by complying with the requirements for conversion set forth in Article 10. 

Section 11.05 Deposit of Redemption Price. Prior to 11:00 a.m., New York City time, on the Redemption Date, the Company will
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, will segregate and hold in trust as provided in Section 2.07 hereof) an amount of immediately available funds
sufficient to pay the Redemption Price of all of the then outstanding Notes. 

  
 - 83 - 








 Section 11.06 Effect of Deposit. If, as of 11:00 a.m., New York City time, on any
Redemption Date, the Company, in accordance with Section 11.05 hereof, has deposited with the Paying Agent money sufficient to pay the Redemption Price for every Note validly delivered in accordance with Section 11.04 hereof (and not
converted before such Redemption Date), then, on such Redemption Date: 
 (A) every Note outstanding on such Redemption Date
will cease to be outstanding and interest, if any, on such Notes will cease to accrue (regardless of whether such Notes were delivered to the Paying Agent or book-entry transfer has been made, as applicable), except to the extent provided in the
proviso to Section 11.02(b); and 
 (B) all other rights of the Holders of such Notes with respect to such Notes (other
than the right to receive payment of the Redemption Price or, in the case of Notes surrendered for conversion in accordance with Article 10 hereof, the right to receive the Conversion Consideration due upon conversion of such Notes, and other than
as provided in the proviso to Section 11.02(b)) will terminate. 
 Section 11.07 Covenant Not to Redeem Notes Upon Certain
Events of Default. 
 (a) General. Notwithstanding anything to the contrary in this Article 11, the Company will not
redeem any Notes under this Article 11 if the principal amount of the Notes has been accelerated and such acceleration has not been rescinded on, or prior to, the Redemption Date (except in the case of an acceleration resulting from a default by the
Company that would be cured by the Company’s payment of the Redemption Price for such Notes). 
 (b) Return of
Notes. If a Holder delivers a Note for redemption pursuant to Section 11.04 and, on the Redemption Date, pursuant to this Section 11.07, the Company is not permitted to redeem such Note, the Paying Agent will (i) if such Note is a
Definitive Note, return such Note to such Holder, and (ii) if such Note is held in book-entry form, in compliance with the Applicable Procedures, deem to cancel any instructions for book-entry transfer of such Note. 

Section 11.08 Repayment to the Company. Subject to any applicable property laws, if, six months after the Redemption Date, any
cash held by the Paying Agent remains unclaimed, the Paying Agent will promptly return such cash to the Company; provided, however, that, to the extent that the aggregate amount of cash deposited by the Company pursuant to
Section 11.05 exceeds the aggregate Redemption Price of every Note outstanding, then as soon as practicable following the Redemption Date, the Trustee will return such excess to the Company.

stockholder, as such, of the Company will not have any liability for any obligations of the Company under the Notes or this Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Note,

Date or Conversion Date is not a Business Day (which, solely for the purposes of any payment required to be made on any such date shall also not include days in which the office where the place of payment is authorized or required by law to close),
then any action to be taken on such date need not be taken on such date, but may be taken on the immediately following Business Day with the same force and effect as if taken on such date, and no interest will accrue for the period from and after
such date. 
 Section 12.16 No Security Interest Created. Except as provided in Section 7.06 or 9.01(b) hereof, nothing in
this Indenture or in the Notes, expressed or implied, will be construed to constitute a security interest under the Uniform Commercial Code or similar legislation, as now or hereafter enacted and in effect, in any jurisdiction. 

Section 12.17 Benefits of Indenture. Nothing in this Indenture or in the Notes, expressed or implied, will give to any Person,
other than the parties hereto, any Paying Agent, Conversion Agent, Registrar, and their successors hereunder, and the Holders any benefit or any legal or equitable right, remedy or claim under this Indenture.

Act, the Trustee, like all financial institutions, in order to help fight the funding of terrorism and money laundering, is required to obtain, verify and record information that identifies each person or legal entity that establishes a relationship

control. 
  

	1.	Interest.

	4.	Repurchase By the Company at the Option of the Holder upon a Fundamental Change. 

 At the
option of the Holder, and subject to the terms and conditions of the Indenture, upon the occurrence of a Fundamental Change, each Holder will have the right, at its option, to require the Company to repurchase for cash all of its Notes, or any
portion of its Notes having a principal amount equal to $1,000 or an integral multiple of $1,000 in excess thereof, at a Fundamental Change Repurchase Price equal to 100% of the principal amount of Notes to be purchased plus accrued and unpaid
interest, if any, to but excluding, the Fundamental Change Repurchase Date, unless the Fundamental Change Repurchase Date occurs after a Regular Record Date and on or prior to the Interest Payment Date corresponding to such Regular Record Date, in
which case the Company will pay the accrued and unpaid interest on such Notes, on such Interest Payment Date, to the Holder of such Notes as of the Close of Business on such Regular Record Date, and the Fundamental Change Repurchase Price shall not
include such accrued and unpaid interest. To exercise its purchase right, a Holder must comply with the procedures set forth in Article 3 of the Indenture. 
  

	5.	Redemption at the Option of the Company. 

 Prior to October 1, 2017, the Company may
not redeem the Notes. Subject to the terms of the Indenture, on or after October 1, 2017, and prior to the Maturity Date, the Company may redeem all, but not less than all, of the Notes if the Last Reported Sale Price of the Common Stock equals
or exceeds 130% of the Conversion Price in effect on each of at least 20 Trading Days during the 30 consecutive Trading Day period ending on the Trading Day immediately prior to the date the Company delivers the Redemption Notice for such
redemption. Any Redemption Date must be at least 45 Scheduled Trading Days, but not more than 60 Scheduled Trading Days, after the date on which the Company delivers the applicable Redemption Notice. The Redemption Price that the Company will pay
for any Notes that it redeems will equal to 100% of the principal amount of Notes to be purchased plus accrued and unpaid interest, if any, to but excluding, the Redemption Date, unless the Redemption Date occurs after a Regular Record Date and on
or before the Interest Payment Date corresponding to such Regular Record Date, in which case the Redemption Price for any Notes to be redeemed will equal 100% of the principal amount of such Notes, and accrued and unpaid interest, if any, on such
Notes to, but excluding, such Interest Payment Date will be payable, on such Interest Payment Date, to the Holder of such Notes at the Close of Business on such Regular Record Date. 

  
 A-7 









	6.	Conversion. 

 Subject to, and upon compliance with, the provisions of Article 10 of the
Indenture, a Holder may, at its option, convert all of its Notes, or any portion of its Notes having a principal amount equal to $1,000 or an integral multiple of $1,000 in excess thereof, (i) subject to satisfaction of the conditions set forth
in Section 10.01(b) of the Indenture, at any time prior to the Close of Business on the Business Day immediately preceding April 1, 2019, under the circumstances and during the periods set forth in Section 10.01(b) of the Indenture,
and (ii) irrespective of the conditions set forth in Section 10.01(b) of the Indenture, on or after April 1, 2019, and prior to the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date, in each
case, into Conversion Consideration, as provided in Article 10 of the Indenture, based on the Conversion Rate. Notes may not be converted after the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date. 

 

	7.	Denominations; Transfer; Exchange. 

 The Notes are in fully registered form, without
coupons, in minimum denominations of $1,000 of principal amount and in integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things,
to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not transfer or exchange any Notes in respect of which a Fundamental Change Repurchase Notice
has been given and not withdrawn (except, in the case of a Note to be repurchased in part, the portion of the Note not to be repurchased), after the Company has delivered a Redemption Notice (except to the extent that Notes are converted or the
Company fails to pay the Redemption Price in accordance with Article 11 of the Indenture) or in respect of which a Conversion Notice has been given (except, in the case of a Note to be converted in part, the portion of the Note not to be converted).

  

	8.	Amendment, Supplement and Waiver. 

 Subject to certain exceptions, the Indenture permits
the Indenture and the Notes to be amended or supplemented with the written consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes. In certain circumstances, the Company and the Trustee may also
amend or supplement the Indenture or the Notes without the consent of any Holder. Subject to certain exceptions, the Indenture permits the waiver of certain Events of Default or the noncompliance with certain provisions of the Indenture and of the
Notes with the written consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes. 
  

	9.	Defaults and Remedies. 

 Subject to the immediately following paragraph, if an Event of
Default specified in the Indenture occurs and is continuing, the Trustee, by delivering a written notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, by delivering a written notice to
the Company and the Trustee, may declare all the Notes to be due and payable immediately by delivering notice to the Company. In addition, certain specified Events of Default will cause the Notes to become immediately due and payable without the
Trustee or Holders taking any action. 

  
 A-8 








 If the Company so elects, the sole remedy for an Event of Default relating to the Company’s
failure to comply with the reporting obligations under Section 4.03 of the Indenture will, for the first 180 days after the occurrence of such Event of Default, consist exclusively of the right to receive an Extension Fee on the principal
amount of the Notes then outstanding. 
 Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee
may refuse to enforce the Indenture or the Notes unless it receives indemnity or security satisfactory to it. Holders of a majority of the principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power,
subject to certain limitations set forth in the Indenture. Subject to certain exceptions, the Trustee may withhold from Holders notice of any continuing Event of Default or Default if it determines that withholding notice is in their interest. 

 

	10.	Persons Deemed Owners. 

 The Holder of this Note will be treated as the owner of this
Note for all purposes. 
  

	11.	Unclaimed Money or Notes. 

 The Trustee and the Paying Agent will return to the Company
upon written request any money or securities held by them for the payment of any amount with respect to the Notes that remain unclaimed for two years, subject to applicable unclaimed property law. After return to the Company, Holders entitled to the
money or securities must look to the Company for payment as general creditors, unless an applicable abandoned property law designates another Person. 
  

	12.	Trustee Dealings with the Company. 

 The Trustee, in its individual or any other
capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it
were not the Trustee. 
  

	13.	Calculations in Respect of Notes. 

 Except as otherwise provided in the Indenture, the
Company will be responsible for making all calculations called for under the Notes and the Indenture. These calculations include, but are not limited to, determinations of the Last Reported Sale Price of the Common Stock or any other security, the
Daily Settlement Amounts, the Daily Conversion Values, accrued interest payable on the Notes and the Conversion Rate in effect on any Conversion Date. 

The Company will make all these calculations in good faith and, absent manifest error, its calculations will be final and binding on all Holders. 

  
 A-9 









	14.	No Recourse Against Others. 

 A director, officer, employee or stockholder, as such, of
the Company will not have any liability for any obligations of the Company under the Notes or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Note, each Holder waives and
releases all such liability. The waiver and release are part of the consideration for the issue of the Notes. 
  

	15.	Authentication. 

 This Note will not be valid until an authorized signatory of the
Trustee manually signs the Trustee’s certificate of authentication on the other side of this Note.

	17.	GOVERNING LAW. 

 THE INDENTURE AND THE NOTES WILL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
  

	18.	CUSIP Numbers.

printed on the Notes or as contained in any notice, and reliance may be placed only on the other identification numbers placed thereon.
