regional securities exchange on which the Common Stock is traded. If the Common Stock is not listed for trading on a U.S. national or regional securities exchange on such date, the “Last Reported Sale Price” of the Common Stock will be the

 Section 1.03 Rules of Construction. 

(a) a term has the meaning assigned to it; 

(b) an accounting term not otherwise defined has the meaning assigned to it and will be construed in accordance with U.S. generally accepted
accounting principles; 
 (c) “or” is not exclusive; 

(d) “including” means including, without limitation; 

(e) words in the singular include the plural, and words in the plural include the singular, unless the context requires otherwise; 

(f) all references to $, dollars, cash payments or money refer to United States currency; and 

(g) unless the context requires otherwise, all references to interest on the Notes (a) will include any Additional Interest payable
pursuant to Section 4.04 hereof and any Extension Fee payable pursuant to Section 6.04 hereof, (b) but, for the avoidance of doubt, will not include any Default Interest payable on a Defaulted Amount pursuant to the terms of
Section 2.04 hereof. 
 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. 
 (a) 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 together with a medallion guarantee, if applicable. Where such execution is by a signer


  
 11 








 
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 instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner that the Trustee deems sufficient. 

(b) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note will bind every future
Holder of the same Note and the Holder of every Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee, the Company, the Paying
Agent, the Conversion Agent or the Registrar in reliance thereon, whether or not notation of such action is made upon such Note. 
 (c) If
the Company will solicit from the Holders any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to a Board Resolution, fix in advance a record date for the determination
of Holders 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, 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 II 

THE NOTES 

Section 2.01 Designation, Amount and Issuance of Notes. 

The Notes will be designated as “4.125% Convertible Senior Notes due 2020.” The initial aggregate principal amount of Notes to be
issued, authenticated and delivered on the Issue Date under this Indenture is $60,000,000. 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. 
 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
or endorsement, or any such insertion, omission or other variation is applicable to a Note, the Company will provide such notation, legend or endorsement, or such insertion, omission or other variation to the Trustee in writing. 

  
 12 








 Each Note will bear a Trustee’s certificate of authentication substantially in the form set
forth in Exhibit A hereto. 
 Notes that are Global Notes will bear the Global Notes Legend and the “Schedule of Increases and
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 definitive form, registered in the name of City Index Group Limited. Except to the extent provided in Section 2.09(d) hereof, all Notes will be represented by one or more Definitive 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. 

  
 13 








 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, 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 April 1, 2020 (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 4.125% 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 October 1, 2015 (or such other date provided for in Section 2.01(b) with respect to Notes issued in accordance with such Section), 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, 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 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. 

  
 14 








 The Company will 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. The Company will 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 4.125% 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: 
 (1) At least 30 days 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. 

  
 15 








 (2) 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 reasonably
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 the day that is
five Business Days 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). 
 (3) 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 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. 

(4) 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, 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. 

  
 16 








 (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 

  
 17 








 
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 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 Corporate Trust Office. 
 (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. 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 

  
 18 








 
exchange, presented for payment, repurchase or redemption or surrendered for conversion, or place where notices and demands to, or upon, the Company with respect to the Notes and this Indenture
may be served, as the case may be, 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. 

(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, forthwith 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.

 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) 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)), every certificate evidencing a 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: 
 (1) 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 (including, for the avoidance of doubt, any Person or entity that was an affiliate of the Company during the immediately preceding three months)) pursuant to a
registration statement that was effective under the Securities Act at the time of such Transfer; or 
 (2) 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 (including, for the avoidance of doubt, any Person or entity that was an affiliate of the Company during the immediately
preceding three months)) 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), 

  
 24 








 and, with respect to clause (2) of this Section 2.10(a)(ii), 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. Except as otherwise provided in this Indenture 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, the Trustee and the Registrar 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. 

(iv) Reinstatement of Restricted Notes Legend. If the Restricted Notes Legend is removed from the face of a Note and the
Note is subsequently held by the Company, an affiliate (as defined in Rule 144) of the Company or any Person or entity that was an affiliate of the Company during the immediately preceding three months, the Restricted Notes Legend will be
reinstated. 
 (b) Restricted Stock. If any shares of Common Stock are issued upon conversion of any Notes, then any certificate
representing such shares of Common Stock will, upon such issuance, bear the Restricted Stock Legend unless: 
 (i) 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 (including, for the avoidance of doubt, any Person or entity that was an affiliate of the Company
during the immediately preceding three months)) pursuant to a registration statement that is effective under the Securities Act at the time of such issuance; 

(ii) 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 (including, for the avoidance of doubt, any Person or entity that was an affiliate of the Company during the immediately preceding three months)) 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 

  
 25 








 (iii) the Company delivers written notice to the Transfer Agent and the Registrar
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 reasonably 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 new Definitive Notes are ready for delivery, the Company may execute
and the Trustee or an authenticating agent appointed by the Trustee will, upon written request of the Company, 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 

  
 26 








 
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 (other than City Index Group Limited; INCAP Gaming B.V.; Sun
Luxco I, Sarl; Sun Luxco II, Sarl; or Francisco Partners II, L.P.) or an Affiliate of such other obligor (other than City Index Group Limited; INCAP Gaming B.V.; Sun Luxco I, Sarl; Sun Luxco II, Sarl; or Francisco Partners II, L.P.) 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. 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). 

(c) In determining whether the Trustee shall be protected in relying upon any request, demand, authorization, direction, notice, consent or
waiver from the Holders, only Notes which a Trust Officer assigned to the Corporate Trust Department of the Trustee knows to be owned by the Company or any other obligor upon the Notes or any Affiliate of the Company or such other obligor (in each
case, other than City Index Group Limited; INCAP Gaming B.V.; Sun Luxco I, Sarl; Sun Luxco II, Sarl; or Francisco Partners II, L.P.) shall be so disregarded. Notes so owned which have been pledged in good faith may be regarded as outstanding if the
pledgee establishes to the satisfaction of the Trustee the pledgee’s right to act as owner with respect to such Notes and that the pledgee is not the Company or any other obligor upon the Notes or any Affiliate of the Company or such other
obligor. 

  
 27 








 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 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

(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.

(xiv) 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 deliver a
Fundamental Change Notice nor a defect in a Fundamental Change Notice delivered by the Company will limit the repurchase rights of any Holder under this Article 3 or impair or otherwise affect the validity of any proceedings relating to the
repurchase of any Note pursuant to this Article 3.

any Notes under this Article 3 if, as of the Fundamental Change Repurchase Date, the principal amount of the Notes has been accelerated, such acceleration has not been rescinded and such acceleration did not result from a Default that would be cured

 Section 4.02 [Reserved]. 

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 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 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 actual or 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.

Sections 13 or 15(d) of the Exchange Act, as applicable (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 one year anniversary of the Issue Date and (ii) the date such failure to file is corrected. 

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. 

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. 

  
 35 








 (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 December 31, 2016, 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 its 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 any
of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided under this Indenture) or, if one or more Defaults or Events of Default have occurred, what events triggered such
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
existence, a description, in reasonable detail, of such event or events and what actions the Company is taking or proposes to take with respect to such event or events. 

(b) Certificate of Default or Event of Default. Within 30 days after a Default occurs, the Company will deliver to the Trustee an
Officers’ Certificate describing such Default, its status and a description, in reasonable detail, of what action the Company is taking or proposes to take with respect to such Default.

 (a) its corporate existence, and the corporate, partnership or other existence of each of its
Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Subsidiary; provided, however, that the Company will not be required to preserve or keep
in full force and effect the corporate, partnership or other existence of any of its Subsidiaries, if the Board of Directors determines that the preservation thereof is no longer desirable in the conduct of the business of the Company and its
Subsidiaries, taken as a whole; and 
 (b) the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries;
provided, however, that the Company will not be required to preserve or keep in full force and effect any such right, license or franchise, or the corporate, partnership or other existence of any of its Subsidiaries, if the Board of

any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this
Indenture; and the Company, to the extent that it may lawfully do so, hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power
herein granted to the Trustee, but will instead suffer and permit the execution of every such power as though no such law has been enacted.

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. 

  
 40 








 (b) Optional Acceleration. If any Event of Default (other than an Event of Default
specified in Sections 6.01(a)(ix) or 6.01(a)(x) hereof) 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. 

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 (i) for the first 90 days after the occurrence of
such a Reporting Event of Default (beginning on, and including, the date on which such a Reporting Event of Default first occurs), consist exclusively of the right to receive special interest on the notes at a rate equal to 0.25% per annum of
the principal amount of such Notes then outstanding for each day during such 90-day period on which such event of default is continuing and (ii) for the period from, and including, the 91st day after the occurrence of such Reporting Event of
Default to, and including, the 180th day after the occurrence of such Reporting Event of Default, consist exclusively of the right to receive special interest on the notes at a rate equal to 0.50% per


  
 41 








 
annum of the principal amount of notes then outstanding for each day during such additional 90-day period on which such event of default is continuing (such special interest, at either 0.25% or
0.50% per annum, as applicable, the (“Extension Fee”). 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 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. 
 (e) 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 the first paragraph of 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. 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. 

  
 42 








 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; 

(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, 

  
 43 








 
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 Section 6.01(a)(i), 6.01(a)(ii), 6.01(a)(iii) 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 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 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 

  
 44 








 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, or, if the Company fails to do so the Trustee will deliver to each
Holder, 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 VII 

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

(b) Except during the continuance of an Event of Default, the Trustee undertakes to perform such duties, and only such duties, as are
specifically set forth in this Indenture, and no implied covenants or obligations will be read into this Indenture against the Trustee and, in the absence of bad faith on its part, the Trustee may conclusively rely upon certificates or opinions
furnished to the Trustee and conforming to the requirements of this Indenture.

performance of any of its duties hereunder or in the exercise of any of its rights or powers. 
 (h) Every provision of this Indenture
relating to the conduct or affecting the liability of or affording protection to the Trustee will be subject to the provisions of this Article 7, and the provisions of this Article 7 will apply to the Trustee, Registrar, Paying Agent and Conversion
Agent.

received written notice at its Corporate Trust Office thereof from the Company or any Holder. 
 Section 7.02 Rights of Trustee.

 (a) The Trustee may conclusively rely upon any document believed by it to be genuine and to have been signed or presented by the proper
person. The Trustee need not investigate any fact or matter stated in the document. The Trustee may, however, in its discretion make such further inquiry or investigation into such facts or matters as it may see fit and, if the Trustee determines to
make such further inquiry or investigation, it will be entitled to examine the books, records and premises of the Company, personally or by agent or attorney and at the expense of the Company, and will incur no liability of any kind by reason of
such inquiry or investigation.

 46 








 (e) The Trustee may consult with counsel of its own selection, and the advice or Opinion of
Counsel with respect to legal matters relating to this Indenture and the Notes will be full and complete authorization and protection from liability in respect to any action taken, omitted or suffered by it hereunder in good faith and in accordance
with the advice or opinion of such counsel. 
 (f) The permissive rights of the Trustee to do things enumerated in this Indenture will not
be construed as a duty unless so specified herein. 
 (g) The Trustee will be under no obligation to exercise any of the rights, trusts or
powers vested in it by this Indenture, and may refuse to perform any duty or exercise any such rights or powers, including but not limited to acting at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders

(i) The Trustee may request that the Company deliver an Officers’ Certificate setting forth the names of individuals and/or titles of
officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may be signed by any Person authorized to sign an Officers’ Certificate, including any Person specified as so authorized in

 (k) The Trustee shall not be charged with knowledge of any default or Event of Default with respect to the Notes for which it is
acting as Trustee unless a Trust Officer has received written notice of such default or Event of Default from the Company or any other obligor on such Notes or from any Holder of such Notes. 

(l) The Trustee will accept all notices, reports and other information that are required to be provided or delivered to it pursuant to the
Indenture, and, where required hereunder, will determine whether such notices, reports or other information are satisfactory to it in form; provided, however that delivery of such reports, information and documents to the Trustee is
for informational purposes only and, except for any explicit notice of an Event of Default from the Company or a Holder, the Trustee’s receipt of such shall not constitute actual or constructive knowledge or notice of any information contained
therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder. 

  
 47 








 (m) The Trustee may request that the Company deliver an Incumbency Certificate setting forth the
names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Incumbency Certificate may be signed by any Person authorized to sign an Officers’ Certificate or any other
Person specified as so authorized in any Incumbency Certificate previously delivered and not superseded. 
 (n) The Trustee shall be under
no liability for interest on any money received by it hereunder except as otherwise agreed in writing with the Company. 
 Section 7.03
Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.
However, if the Trustee acquires any conflicting interest it must eliminate the conflict within 90 days or resign. Any Paying Agent, Registrar, Conversion Agent or co-registrar may do the same with like rights. However, the Trustee must comply with
Section 7.09 hereof. 
 Section 7.04 Trustee’s Disclaimer. The recitals contained herein and in the Notes, except the
certificates of authentication, shall be taken as the statements of the Company, and the Trustee assumes no responsibility for their correctness. The Trustee will not be responsible for and makes no representation as to the validity, priority or
adequacy of this Indenture or the Notes, it will not be accountable for the Company’s use of the proceeds from the Notes, and it will not be responsible for any statement of the Company in this Indenture or in any document issued in connection
with the sale of the Notes or in the Notes other than the Trustee’s certificate of authentication. The Trustee shall not be responsible or liable for any failure of the Company or any other party to comply with any securities laws, including,
without limitation, the U.S. Securities Act of 1933, as amended and the U.S. Investment Company Act of 1940, as amended. 

Section 7.05 Notice of Defaults. If a Default occurs and is continuing and a responsible officer of the Trustee is notified in
writing of such default, the Trustee will send to each Holder notice of the Default within 90 days after such Default first occurs, or, if it is not known to the Trustee at such time, as soon as practicable after a responsible officer of the Trustee
receives such notice; provided, however, that except in the case of a Default that is, or would lead to, an Event of Default described in Section 6.01(a)(i), 6.01(a)(ii) or 6.01(a)(iv) hereof, the Trustee may withhold the notice
if and so long as a committee 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 reasonable compensation 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, 

  
 48 








 
accountants and experts. The Company will fully indemnify the Trustee against any and all loss, liability, claim, damage or expense (including reasonable attorneys’ fees and expenses)
incurred by it in connection with the acceptance and administration of this trust or 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, 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 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 gross 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. 

(b) If the indemnification provided for in the preceding paragraph is invalid or unenforceable in accordance with its terms, then the Company
shall contribute to the amount paid or payable by the Trustee as a result of such liability in such proportion as is appropriate to reflect the relative benefits received by the Company on one hand and the Trustee on the other from the transactions
relating to the Indenture. 
 (c) The term “liability”, as used herein, shall mean any losses, claims, damages, expenses
(including without limitation the Trustee’s reasonable and documented costs and expenses in defending itself against any losses, claims or investigations of any nature whatsoever or in bringing an action) or other liabilities, joint or several,
arising out of or in connection with any claim, litigation, investigation or proceeding relating to the Indenture and any transactions contemplated thereby (including, without limitation, any claim, litigation, investigation or proceeding asserting
violation of applicable laws). 
 (d) 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. 
 (e) 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. 

  
 49

(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.

 50

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 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. 
 Section 7.11
Withholding. In order to comply with applicable tax laws (inclusive of rules, regulations and interpretations promulgated by competent authorities) related to this Indenture in effect from time to time (“Applicable Tax Law”) that a
foreign financial institution, the Company, Trustee, Paying Agent or other party is (or has agreed to be) subject to, the Company agrees (i) upon the reasonable request of the Trustee or the Paying Agent to provide to the Trustee and the Paying
Agent information about the Notes (including any modification to the terms of such Notes) that the Company has in its possession, sufficient to permit the Trustee and Paying Agent to determine whether it has tax related obligations under Applicable
Law, (ii) that the Trustee and the Paying Agent shall be entitled to make any withholding or deduction from payments to the extent necessary to comply with Applicable Tax Law, and (iii) pursuant to Section 7.06(a) and subject to the

 ARTICLE VIII  

SATISFACTION AND DISCHARGE 

Section 8.01 Discharge of Liability on Notes. When (a)(i) the Company delivers to the Registrar all outstanding Notes (other than
Notes replaced pursuant to Section 2.11 hereof) for cancellation or (ii) all outstanding Notes have become due and payable, and the Company irrevocably deposits with the Trustee or delivers to the Holders, as applicable, cash and/or shares
of Common Stock (or, if applicable, Reference Property) and cash (in lieu of fractional shares of Common Stock or, if applicable, Reference Property Units) (solely to satisfy amounts due and owing as a result of conversions of the Notes), sufficient
to pay all amounts due and owing on all outstanding Notes (other than Notes replaced pursuant to Section 2.11 hereof), (b) the Company pays all other sums payable by it under this Indenture with respect to the then outstanding Notes and
(c) the Company delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such discharge is authorized and permitted under this Indenture and that all of the applicable conditions precedent to the
discharge of this Indenture have been satisfied, then, subject to Section 7.06 hereof, this Indenture will cease to be of further effect with respect to the Notes and the Holders and the Trustee will acknowledge the satisfaction and discharge
of this Indenture with respect to the Notes. 
 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. 
 Section 8.02 Repayment to the
Company. Subject to any applicable unclaimed property law, the Trustee and the Paying Agent, upon receiving a written request from the Company, will promptly turn over to the Company any cash, securities, including shares of Common Stock, or
other property held for payment on the Notes that remains unclaimed two years after the date on which such payment was due. After the Trustee and the Paying Agent return such cash and securities, including shares of the Common Stock, to the Company,
the Trustee and the Paying Agent will have no further liability to any Holder with respect to such cash, securities, including shares of Common Stock, or other property, and any Holder entitled to the payment of such cash, securities, including
shares of Common Stock, or other property under the Notes or this Indenture must look to the Company for payment as a general creditor of the Company.

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.

 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 and during the periods set forth in Section 10.01(b), at
any time prior to the Close of Business on the Business Day immediately preceding October 1, 2019 and 

  
 55 








 
(ii) irrespective of the conditions set forth in Section 10.01(b), on or after October 1, 2019, and prior to the Close of Business on the Business 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 Business Day immediately preceding the Maturity Date. 

(b) Conditions to Conversions Prior to the Close of Business on the Business Day Immediately Preceding October 1, 2019. Prior to
the Close of Business on the Business Day immediately preceding October 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 October 1, 2019, a Holder may present its Notes for conversion during any calendar quarter commencing after the calendar quarter ending on September 30, 2015 (and only during such calendar quarter), if the Last Reported Sale
Price per share of the Common Stock for each of at least twenty (20) Trading Days (whether or not consecutive) during the thirty (30) consecutive Trading days ending on, and including, the last Trading Day of the immediately preceding
calendar quarter is greater than one hundred and thirty percent (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 October 1, 2019, a Holder may convert its Notes during the five (5) consecutive Business Day period immediately after any five (5) consecutive Trading Day period, (the “Measurement Period”), in which
the Trading Price per $1,000 principal amount of the Notes, as determined following a request by a Holder in accordance with the procedures set forth below, for each Trading Day of the Measurement Period was less than ninety eight percent
(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) unless a Holder of at least $1.0 million 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 ninety eight percent (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 ninety eight percent
(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 

  
 56 








 
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 ninety eight percent (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. 

(1) Certain Distributions. If, prior to the Close of Business on the Business Day immediately preceding October 1,
2019, the Company elects to: 
 (A) 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 sixty (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 ten (10) consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance; or 

(B) 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 ten percent (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 at least thirty
(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 5:00 p.m., New York City time, on
the Business Day immediately preceding such Ex-Dividend Date and the Company’s announcement, if any, that such issuance or distribution will not take place. 

(2) Certain Corporate Events. If, prior to the Close of Business on the Business Day immediately preceding
October 1, 2019, either (i) a transaction or event that constitutes a Fundamental Change occurs; (ii) a transaction or event that constitutes a Make-Whole Fundamental Change, pursuant to clause (i) of such definition 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 until the earlier of
(x) thirty five (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 Scheduled Trading Day immediately 

  
 57 








 
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 prior to the Close of Business on the
Business Day immediately preceding October 1, 2019, then the Holder of such Note may surrender the Note for conversion at any time before the Close of Business on the 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 delivers 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.

 The first date 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. 

  
 58 








 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 and the documents required by Sections 12.03 and
12.04 hereof, 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 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 

  
 59 








 
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. Upon the conversion of any Note, the Company shall settle such conversion by paying or
delivering, as applicable and as provided in this Article 10, either (A) solely cash (a “Cash Settlement”); (B) shares of Common Stock, together, if applicable, with cash in lieu of fractional shares as provided in
Section 10.03(a)(ii)(1) (a “Physical Settlement”); or (C) a combination of cash and shares of Common Stock, together, if applicable, with cash in lieu of fractional shares as provided in Section 10.03(a)(ii)(3) (a
“Combination Settlement”). The Company shall have the right to elect the Settlement Method applicable to any conversion of a Note; provided, however, that: 

(1) (x) all conversions of Notes whose Conversion Date occurs on or after October 1, 2019 will be settled using the same
Settlement Method, and the Company shall send written notice of such Settlement Method to Holders, through the Trustee, no later than the Close of Business on the Business Day immediately preceding October 1, 2019 and (y) all conversions
for which the Conversion Date occurs during the Redemption Conversion Period will be settled using a single Settlement Method and the Company shall send written notice of such Settlement Method to Holders, through the Trustee concurrently with
delivery of the Redemption Notice; 
 (2) 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 (a)(i)(1) above); 

  
 60 








 (3) if the Company elects a Settlement Method with respect to the conversion of
any Note whose Conversion Date occurs before October 1, 2019 and not during a Redemption Conversion Period, the Company shall send written notice of such Settlement Method to the Holder of such Note, through the Trustee, no later no later than
the Close of Business on the second Scheduled Trading Day immediately following such Conversion Date; 
 (4) if the Company
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; 

(5) 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; and 

(6) the Settlement Method shall be subject to clause (II) of the first sentence of Section 10.08(a). 

(ii) Conversion Consideration. Subject to Section 10.03(a)(iv), 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: 

(1) 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 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; 

(2) if Cash Settlement applies to such conversion, cash in an amount equal to the sum of the Daily Conversion Values for each
of the twenty five (25) consecutive Trading Days in the Observation Period for such conversion; or 
 (3) if
Combination Settlement applies to such conversion, a settlement amount equal to (I) the sum of the Daily Settlement Amounts for each of the twenty five (25) 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. 

  
 61 








 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. 

(iii) 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
(3rd) 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 (3rd) 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 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. 

Section 10.04 Common Stock Issued Upon Conversion. 

(a) On or prior to the Issue Date, the Company will reserve out of its authorized but unissued shares of Common Stock, for delivery upon
conversion of Notes under this Indenture, a number of shares of Common Stock equal to the maximum number of shares of Common Stock issuable upon conversion of all Notes assuming all such conversions were settled by delivering solely shares of Common
Stock (other than cash in lieu of any fractional shares of Common Stock). 

  
 62 








 (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 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 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: 
  

					
	 CR1 = CR0     x    
		OS1  		
		OS0		

 where 
  

					
	CR0		=		the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the Open of Business on the Effective Date of such share split or share
combination, as applicable;
			
	CR1		=		the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date or the Open of Business on such Effective Date;


  
 63 









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

 If any dividend or distribution 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, to
the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 (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: 
  

					
	 CR1 = CR0    x    
		OS0 + X		
		OS0 + Y		

 where 
  

					
	CR0		=		the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such issuance;
			
	CR1		=		the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;
			
	OS0		=		the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date;
			
	X		=		the total number of shares of Common Stock issuable pursuant to such rights, 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 

  
 64 








 
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. 

(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: 

(1) dividends, distributions and issuances described in Section 10.05(a) hereof or Section 10.05(b) hereof, as
applicable; 
 (2) dividends or distributions paid exclusively in cash described in Section 10.05(d) hereof; and 

(3) 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: 
  

					
	  
 CR1 = CR0     x    
		        SP0          
  		
		SP0 – FMV		

 where 
  

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


  
 65 








 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 to acquire Capital Stock of the Company 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. 

If such distribution 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 U.S. national securities exchange or a reasonably comparable non-U.S. equivalent (as determined by the Board of Directors) (a “Spin-Off”), the
Conversion Rate will be increased based on the following formula: 
  

					
	CR1 = CR0    x    		FMV0 + MP0		
		MP0		

 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.


  
 66 








 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, with retroactive effect. 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. 
 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: 

(1) a dividend or distribution of shares of Common Stock to which Section 10.05(a) hereof applies (a “Clause A
Distribution”); or 
 (2) 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 described in Section 10.05(e), and other than a regular, quarterly cash dividend that does not exceed $0.05 per share (the “Dividend
Threshold,” which Dividend Threshold shall be subject to adjustment as set forth below in this Section 10.05(d))) is made to 

  
 67 








 
all or substantially all holders of the Common Stock, the Conversion Rate will be increased based on the following formula: 

 

					
	  
 CR1 = CR0    x    
		SP0 – T		
		SP0 – C		

 where 
  

					
	CR0		=		the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such dividend or distribution;
			
	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;
			
	T		=		the Dividend Threshold; provided, however, that if the dividend or distribution is not a regular quarterly cash dividend, then the Dividend Threshold will be deemed to be zero (0); and
			
	C		=		the amount in cash per share the Company distributes to holders of Common Stock.

 The Dividend Threshold shall be adjusted in a manner inversely proportional to adjustments to the Conversion
Rate pursuant to this Section 10.05; provided, however, that no adjustment will be made to the Dividend Threshold for any adjustment to the Conversion Rate pursuant to this Section 10.05(d). 

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 such dividend or distribution 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 of its Subsidiaries makes a payment in respect of a tender offer or
exchange offer for the Common Stock (other than an odd lot tender offer), 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: 

 

					
	 CR1 = CR0    x    
		AC + (SP1 x OS1)		
		OS0 x SP1		


  
 68 








 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);
		
	 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, with retroactive effect. 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 (3rd) Business Day after the last
day of the Averaging Period. 
 (f) Successive Adjustments. After an adjustment to the Conversion Rate under this Article 10 having
been made, 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-

  
 69 








 
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. 

(i) Shareholder Rights Plans. If the Company has rights plan in effect when a Holder converts a Note, the Company will deliver to such
Holder, in addition to any shares of Common Stock otherwise issuable to such Holder upon 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. 
 (j) Other Adjustments. Whenever any provision of this Indenture requires the calculation of the Last
Reported Sale Price, a Daily VWAP or a function thereof over a period of multiple days (including any Observation Period), 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. 

(k) Restrictions on Adjustments. Except as a result of a reverse share split or share combination subject to Section 10.05(a), in
no event will the Conversion Rate be adjusted downward pursuant to the formulae set forth in 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; 

  
 70 








 (iv) for a change in the par value of the Common Stock; or 

(v) for accrued and unpaid interest. 

(l) 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(l), 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(l), and such adjustments will no longer be carried forward and taken into account in any future adjustment. 

(m) Miscellaneous. 

(i) Certain Definitions. 

(1) 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. 
 (2) 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. 

(3) 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. 

  
 71 








 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. 
 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 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 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. On the same day the Company mails 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. 

Section 10.07 Conversions in Connection with Certain Make-Whole Fundamental Changes. 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 

  
 72 








 
definition of Fundamental Change in which the holders of the Common Stock receive only cash in consideration for their shares of Common Stock, for any conversion of Notes on or following the
Make-Whole Fundamental Change Effective Date for such Make-Whole Fundamental Change, 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 and (ii) the Stock Price for such Make-Whole Fundamental Change. For purposes
of this Section 10.07, a conversion of Notes will be deemed to be “in connection with” a Make-Whole Fundamental Change described in clause (b)(ii) of the definition of “Fundamental Change” if (A) for Conversion
Dates prior to October 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)(2) and (B) for Conversion Dates
on or after October 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). 
 Section 10.08 Effect of Recapitalization, Reclassification, Consolidation,
Merger or Sale. 
 (a) General. If any of the following events occur: 

(i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or
combination or change only in par value or from par value to no par value or no par value to par value); 
 (ii) any
consolidation, merger or combination involving the Company; 
 (iii) any sale, lease or other transfer to a third party of
the consolidated assets of the Company and its Subsidiaries substantially as an entirety; or 
 (iv) any statutory share
exchange, 
 and, in each case, as a result of which the Common Stock would be converted into, or exchanged for, or represent solely the right to receive,
stock, other securities, other property or assets (including cash or any combination thereof) (such stock, other securities, other property or assets, the “Reference Property,” and the amount and kind of Reference Property that a holder of
one share of Common Stock would be entitled to receive on account of such transaction, a “Reference Property Unit”), then, notwithstanding anything to the contrary herein or in the Notes, (I) at the effective time of such transaction,
the Conversion Consideration due upon conversion of any Notes, and the conditions to any such conversion, will be determined in the same manner as if each reference to any number of shares of Common Stock in this Article 10 were instead a reference
to the same number of Reference Property Units; and (II) if such Reference Property Unit consists entirely of cash, then the Company will be deemed to elect 

  
 73 








 
Cash Settlement in respect of all conversions whose Conversion Date occurs on or after the effective date of the Merger Event and shall pay the cash due upon such conversions no later than the
third (3rd) Business Day after the relevant Conversion Date. For these purposes, the Daily VWAP or Last Reported Sale Price of any Reference Property Unit or portion thereof that does not consist of a class of securities will be the fair value
of such Reference Property Unit or portion thereof, as applicable, determined in good faith by the Company (or, in the case of cash denominated in U.S. dollars, the face amount thereof). An event requiring a change to the Conversion Consideration as
provided in the immediately preceding sentence is herein referred to as a “Merger Event,” and the resulting, surviving or transferee Person (if other than the Company) of such Merger Event is herein referred to as the “Merger
Successor Corporation.” At or before the effective date of such Merger Event, the Company and such Merger Successor Corporation will execute and deliver to the Trustee a supplemental indenture pursuant to Section 9.03 hereof, which
supplemental indenture will (i) comply with the TIA as in force on the date such supplemental indenture is executed if this Indenture is then qualified under the TIA and such supplemental indenture is required by law to so comply;
(ii) provide for subsequent conversions of Notes in the manner set forth in the first sentence of this Section 10.08(a); and (iii) provide for subsequent adjustments to the Conversion Rate pursuant to Section 10.05 in a manner
that would have, as determined by the Board of Directors in good faith, an economic effect on the Holders as nearly equivalent as practicable to the economic effect the adjustments provided by Section 10.05 hereof would have had on the Holders
but for such Merger Event. Following such transaction or event, the Company will continue to have the right to settle conversions of the Notes by paying cash, delivering Reference Property or paying and delivering, as the case may be, a combination
of cash and Reference Property, at the Company’s election, subject to certain limitations, as provided in Section 10.03 above. 

If the Reference Property consists of more than a single type of consideration (determined based in part upon any form of shareholder
election), then the composition of the Reference Property Unit will be deemed to be the weighted average, per share of Common Stock, of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an
election (or, if no holders of Common Stock affirmatively make such an election, the types and amounts of consideration actually received by the holders of Common Stock). The Company shall notify Holders of the weighted average as soon as
practicable after such determination is made. 
 If the Reference Property Unit for a Merger Event includes shares of stock or other
securities or assets of a Person other than the Merger Successor Corporation for such Merger Event, then such other company will also execute such supplemental indenture and such supplemental indenture will contain whatever additional provisions the
Board of Directors considers to be reasonably necessary to protect the Holders and to calculate the value of a Reference Property Unit. 

(b) In connection with any adjustment to the Conversion Rate described above, the Company will also adjust the Dividend Threshold based on the
number of shares of Common Stock comprising the Reference Property Units and (if applicable) the value of any non-stock consideration comprising the Reference Property Units. If the Reference Property Units are composed solely of non-stock
consideration, the Dividend Threshold will be zero. 

  
 74 








 (c) Notices. 

(i) As soon as practicable upon learning the anticipated or actual effective date of any Merger Event, the Company will deliver
written notice of such Merger Event to each Holder and the Trustee. Such Notice will include: 
 (1) a brief description of
such Merger Event; 
 (2) the Conversion Rate in effect on the date the Company delivers such notice; 

(3) the anticipated effective date for the Merger Event; 

(4) that, on and after the effective date for the Merger Event, the Notes will be convertible into Reference Property Units
and cash in lieu of fractional Reference Property Units; and 
 (5) the composition of the Reference Property Unit for such
Merger Event. 
 (ii) As promptly as practicable after executing a supplemental indenture in accordance with
Section 10.08(a) hereof, the Company will: 
 (1) file with the Trustee an Officers’ Certificate briefly
describing the reasons therefor, the composition of the Reference Property Unit for such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent under this Indenture to such Merger Event have been complied
with; and 
 (2) 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 Merger Event; provided, that the failure to deliver such notice to any Holder will not affect the validity or legality of such supplemental indenture. 

(d) Successive Merger Events. If more than one Merger Event occurs, this Section 10.08 will apply successively to each Merger
Event. 
 (e) Compliance Covenant. The Company will not become a party to any Merger 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 

  
 75 








 
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 Merger 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. 
 Section 10.10 [Reserved]. 

Section 10.11 Exchange in Lieu of Conversion. Notwithstanding anything herein to the contrary, when a Holder surrenders Notes for
conversion, the Company may, at its election, direct the Conversion Agent to surrender, on or prior to the scheduled Trading Day immediately preceding the first Trading Day of the applicable Observation Period (or, if the Company has elected
Physical Settlement, on or prior to the second Business Day immediately following the relevant Conversion Date), such notes to a financial institution designated by the Company for exchange in lieu of conversion (the “Financial
Institution”). In order to accept any Notes surrendered for conversion, the Financial Institution must agree to pay and/or deliver, as the case may be, in exchange for such Notes, all of the cash, shares of Common Stock or a combination thereof
due upon conversion, all in accordance with Section 10.03 above. By the close of business on the Scheduled Trading Day immediately preceding the first trading day of the applicable Observation Period (or, if the Company has elected Physical
Settlement, by the close of business on the second Business Day immediately following the relevant Conversion Date), the Company will notify the Holder surrendering notes for conversion that the Company has directed the Financial Institution to make
an exchange in lieu of conversion. If the Financial Institution accepts any such Notes, it will pay and/or deliver, as the case may be, the cash, shares or Common Stock or a combination thereof due upon conversion to the Conversion Agent, and the
Conversion Agent will pay and/or deliver such cash and/or shares of Common Stock to the Holder on the third Business Day immediately following the last Trading Day of the applicable Observation Period (or, if the Company has elected Physical
Settlement, on the third Business Day immediately following the relevant Conversion Date). Any Notes exchanged by the Financial Institution will remain outstanding. If the Financial Institution agrees to accept any Notes for exchange but does
not timely pay and/or deliver the related cash, shares of Common Stock or a combination thereof, as the case may be, or if the Financial Institution does not accept the Notes for exchange, the Company shall, as promptly as practical thereafter,
convert the Notes and pay and/or deliver, as the case may be, the cash, shares or Common Stock or a combination thereof due upon conversion on the third Business Day immediately following the last Trading Day of the applicable Observation Period
(or, if the Company has elected Physical Settlement, on the third Business Day immediately following the relevant Conversion Date) as provided in Section 10.03 above. The Company’s designation of the Financial Institution to which the
Notes may be submitted for exchange does not require the Financial Institution to accept any Notes (unless the Financial Institution has separately made an agreement with the Company). The Company may, but will not be obligated to, enter into a
separate agreement with any Financial Institution that would compensate it for any such transaction.

 ARTICLE XI  

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 April 1, 2018, the Company may not redeem the Notes. On or after April 1, 2018, 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, whether or not consecutive, 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 any accrued and unpaid interest 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 20 Business Days, nor more than 45 Business Days, immediately following the date on which the Company delivers such Redemption Notice. 

Section 11.03 Redemption Notice. At least 20 Business Days but not more than 45 Business Days prior to any Redemption Date, the
Company will send to each Holder (and to any beneficial owner of a Global Note, as required by applicable law) 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 or announce such redemption on its website or through such other public medium as the Company may use at such time. 

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; 

  
 77 








 (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; 

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

(h) 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 
 (i) 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 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. 
 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


  
 78 








 
accordance with Section 11.04 hereof (and not converted before such Redemption Date), then, at the Close of Business on such Redemption Date: 

(a) every Note outstanding immediately prior to the Close of Business 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 During a Continuing Acceleration With Respect to the Notes 

(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 be cancelled 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.

The waiver and release will be part of the consideration for the issuance of the Notes.

GAIN CAPITAL HOLDINGS, INC. 

4.125% Convertible Senior Notes due 2020 

This Note is one of a duly authorized issue of notes of GAIN Capital Holdings, Inc. (the “Company”), designated as its 4.125%
Convertible Senior Notes due 2020 (the “Notes”), all issued or to be issued under and pursuant to an indenture dated as of the Issue Date (the “Indenture”), between the Company and The Bank of New York Mellon (the
“Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the
Holders. Capitalized terms used herein and not defined herein have the meanings ascribed to them in the Indenture, and the terms of the Notes include those stated in the Indenture and those incorporated into the Indenture. Notwithstanding anything

Interest on this Note will accrue from the most recent date to which interest has been paid or provided for, or, if no interest has been paid or provided for, the Issue Date. Interest will be payable semiannually in arrears on April 1 and

	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 April 1, 2018, the Company may
not redeem the Notes. Subject to the terms of the Indenture, on or after April 1, 2018, 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, whether or not consecutive, 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 20 Business Days, but not more than 45 Business 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-2 









	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 and
during the periods 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 October 1, 2019 and (ii) irrespective of the conditions set forth in
Section 10.01(b) of the Indenture, on or after October 1, 2019, and prior to the Close of Business on the Business 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 Business 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. 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-3 








 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, beginning on, and including, the date of which such an Event of Default first
occurs, 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-4 









	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. 
  

	16.	Abbreviations. 

 Customary abbreviations may be used in the name of a Holder or an
assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with right of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act). 

 

	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. 

 Pursuant to a recommendation promulgated by the Committee on Uniform
Note Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers in any notices as a convenience to Holders. No representation is made as to the accuracy of such numbers either as
printed on the Notes or as contained in any notice, and reliance may be placed only on the other identification numbers placed thereon. 

The Company will furnish to any Holder, upon written request and without charge, a copy of the Indenture which has in it the text of this
Note. Requests may be made to:
