held by such custodian for the account of the holder of a depository receipt; provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depository receipt from any
amount received by the custodian in respect of the U.S. Government Obligation or the specific payment of interest on or principal of the U.S. Government Obligation evidenced by such depository receipt.

“obligor” on the indenture Notes means the Company. 

All other TIA terms used in this Indenture that are defined by the TIA, defined by TIA reference to another statute or defined by SEC
rule have the meanings assigned to them by such definitions. 
 Section 1.04. Rules of Construction. Unless the context
otherwise requires: 
 (a) a term has the meaning assigned to it; 

(b) an accounting term not otherwise defined has the meaning assigned to it in accordance with generally accepted accounting principles
as in effect from time to time; 
 (c) “or” is not exclusive; 

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

  
 8 

 (e) words in the singular include the plural, and words in the plural include the singular.

 Section 1.05. Acts of Holders. (a) 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 their agent duly appointed in writing; and,
except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, 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
shall 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. 
 (b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer
authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to such officer the execution thereof. Where such execution is by a signer acting in a capacity other than such
signer’s individual capacity, such certificate or affidavit shall 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 which the Trustee deems sufficient. 
 The ownership of Notes shall be proved
by the Note Register or by a certificate of the Note Registrar. 
 Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Note shall 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 or the Company in reliance thereon, whether or not notation of such action is made upon such Note. 
 If the Company shall 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 resolution of the
Board of Directors, 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 shall 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 shall be deemed to
be Holders for purposes of determining whether Holders of the requisite proportion of 

  
 9 

 
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 shall
be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than
six months after the record date. 
 ARTICLE 2 
 THE NOTES 
 Section 2.01.
Designation Amount and Issue of Notes. The Notes shall be designated as “51/4% Convertible Senior Notes due 2013”. Except pursuant to Sections 2.07, 2.08, 3.08 and 10.02 hereof, Notes not to exceed the aggregate
principal amount of $67,832,000 upon the execution of this Indenture, or from time to time thereafter, may be executed by the Company and delivered to the Trustee for authentication, and the Trustee shall thereupon authenticate and deliver said
Notes upon a Company Order, without any further action by the Company hereunder. 
 Section 2.02. Form of Notes.
The Notes and the Trustee’s certificate of authentication to be borne by such Notes shall be substantially in the form set forth in Exhibit A, which is incorporated in and made a part of this Indenture. 

Any of the Notes may have such letters, numbers or other marks of identification and such notations, legends and endorsements as the
officers executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Indenture, or as may be required to comply with any law or with any rule or regulation
made pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Notes may be listed, or to conform to usage. 
 Any Global Note shall represent such of the outstanding Notes as shall be specified therein and shall provide that it shall represent the aggregate amount of outstanding Notes from time to time endorsed
thereon and that the aggregate amount of outstanding Notes represented thereby may from time to time be increased or reduced to reflect transfers or exchanges permitted hereby. Any endorsement of a Global Note to reflect the amount of any increase
or decrease in the amount of outstanding Notes represented thereby shall be made by the Trustee, in such manner and upon instructions given by the holder of such Notes in accordance with this Indenture. Payment of principal of, and interest on, any
Global Note shall be made to the holder of such Note. 
 The terms and provisions contained in the form of Note attached as
Exhibit A hereto shall 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. 

  
 10 

 Section 2.03. Execution and Authentication. The Notes shall be executed on behalf of
the Company by an Officer of the Company, under its corporate seal reproduced thereon, which may be manual or facsimile. The signatures of such Officer on the Notes may be manual or facsimile. 

Notes bearing the manual or facsimile signatures of individuals who were at the time of the execution of the Notes the proper Officers of
the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Notes or did not hold such offices at the date of authentication of such
Notes. Notes shall be dated the date of their authentication. 
 No Note shall be entitled to any benefit under this Indenture
or be valid or obligatory for any purpose unless there appears on such Note a certificate of authentication substantially in the form provided for herein duly executed by the Trustee or an Authenticating Agent by manual signature of an authorized
officer, and such certificate upon any Note shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered hereunder. 
 The Notes shall be issued only in registered form without coupons and only in denominations of $1,000 in principal amount and any integral multiple thereof. 

Section 2.04. Note Registrar, Paying Agent and Conversion Agent. The Company shall maintain an office or agency where Notes may be
presented for registration of transfer or for exchange (“Note Registrar”), an office or agency where Notes may be presented for purchase or payment (“Paying Agent”) and an office or agency where Notes may be
presented for conversion (“Conversion Agent”). The Note Registrar shall keep a register (the “Note Register”) in which, subject to such reasonable regulations as it may prescribe it shall provide for the
registration and transfer of the Notes. The Company may have one or more co-registrars, one or more additional paying agents and one or more additional conversion agents. The term Paying Agent includes any additional paying agent, including any
named pursuant to Section 4.05. The term Conversion Agent includes any additional conversion agent, including any named pursuant to Section 4.05. 
 The Company shall notify the Trustee of the name and address of any such agent. If the Company fails to maintain a Note Registrar, Paying Agent or Conversion Agent, the Trustee shall act as such and shall
be entitled to appropriate compensation therefor pursuant to Section 7.06. The Company or any Subsidiary or an Affiliate of either of them may act as Paying Agent, Note Registrar, Conversion Agent or co-registrar. 

The Company initially appoints the Trustee as Note Registrar, Conversion Agent and Paying Agent in connection with the Notes. 

  
 11 

 Section 2.05. Paying Agent to Hold Money and Notes in Trust. Except as otherwise
provided herein, on or prior to each due date of payments in respect of any Note, the Company shall deposit with the Paying Agent a sum of money (in immediately available funds if deposited on the due date) or Common Stock sufficient to make such
payments when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Noteholders or the Trustee all money and Common Stock held by the
Paying Agent for the making of payments in respect of the Notes and shall notify the Trustee of any default by the Company in making any such payment. At any time during the continuance of any such default, the Paying Agent shall, upon the written
request of the Trustee, forthwith pay to the Trustee all money and Common Stock so held in trust. If the Company, a Subsidiary or an Affiliate of the Company acts as Paying Agent, it shall segregate the money and Common Stock held by it as Paying
Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money and Common Stock held by it to the Trustee and to account for any funds and Common Stock disbursed by it. Upon doing so, the Paying Agent
shall have no further liability for the money or Common Stock. 
 Section 2.06. Noteholder Lists. The Trustee shall
preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Noteholders. If the Trustee is not the Note Registrar, the Company shall cause to be furnished to the Trustee at least
semiannually on January 1 and July 1 a listing of Noteholders dated within 15 days of the date on which the list is furnished and at such other times as the Trustee may request in writing a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of Noteholders. 
 Section 2.07. Transfer and Exchange;
Restrictions; Global Note; Depositary. (a) Upon surrender for registration of transfer of any Note, together with a written instrument of transfer satisfactory to the Note Registrar duly executed by the Noteholder or such Noteholder’s
attorney duly authorized in writing, at the office or agency of the company designated as Note Registrar or co-registrar pursuant to Section 2.04, and satisfaction of the requirements of such transfer set forth in this Section, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denomination or denominations, of a like aggregate principal amount and bearing such
restrictive legends as may be required by this Indenture. The Company shall not charge a service charge for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to pay all taxes, assessments or other
governmental charges that may be imposed in connection with the transfer or exchange of the Notes from the Noteholder requesting such transfer or exchange. At the option of the Holder, Notes may be exchanged for other Notes of any authorized
denomination or denominations, of a like aggregate principal amount, upon surrender of the Notes to be exchanged, together with a written instrument of transfer satisfactory to the Note Registrar duly executed by the Noteholder or such
Noteholder’s attorney duly authorized in writing, at such office or agency. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes which the Holder making the
exchange is entitled to receive. 

  
 12 

 All Notes issued upon any registration of transfer or exchange of Notes shall be the valid
obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange. 

The Company shall not be required to make, and the Note Registrar need not register, transfers or exchanges of any Notes in respect of
which a Change of Control Purchase Notice (as defined in Section 3.05(d)) has been given and not withdrawn by the Holder thereof in accordance with the terms of this Indenture (except, in the case of Notes to be purchased in part, the portion
thereof not to be purchased). 
 (b) So long as the Notes are eligible for book-entry settlement with the Depositary, or unless
otherwise required by law, all Notes that, upon initial issuance are beneficially owned by QIBs or as a result of a sale or transfer after initial issuance are beneficially owned by QIBs, will be represented by one or more Notes in global form
registered in the name of the Depositary or the nominee of the Depositary (the “Global Note”), except as otherwise specified below. The transfer and exchange of beneficial interests in any such Global Note shall be effected through
the Depositary in accordance with this Indenture and the procedures of the Depositary therefor. The Trustee shall make appropriate endorsements to reflect increases or decreases in the principal amounts of any such Global Note as set forth on the
face of the Note (“Principal Amount”) to reflect any such transfers. Except as provided below, beneficial owners of a Global Note shall not be entitled to have certificates registered in their names, will not receive or be entitled
to receive physical delivery of certificates in definitive form (“Certificated Notes”) and will not be considered holders of such Global Note. 
 (c) So long as the Notes are eligible for book-entry settlement with the Depositary, or unless otherwise required by law, upon any transfer of a Certificated Note to a QIB that requests delivery of such
Note in the form of an interest in the Global Note, and upon receipt of the Certificated Note or Notes being so transferred, the Trustee shall make an endorsement on the Global Note to reflect an increase in the aggregate Principal Amount of the
Notes represented by such Global Note, and the Trustee shall cancel such Certificated Note or Notes in accordance with the standing instructions and procedures of the Depositary. 

Any Global Note may be endorsed with or have incorporated in the text thereof such legends or recitals or changes not inconsistent with
the provisions of this Indenture as may be required by the Trustee, the Depositary or by the National Association of Securities Dealers, Inc. in order for the Notes to be tradeable on The Portal Market or as may be required for the Notes to be
tradeable on any other market developed for trading of securities or required to comply with any applicable law or any regulation thereunder or with the rules and regulations of any securities exchange or automated quotation system upon which the
Notes may be listed or traded or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to which any particular Notes are subject. 

  
 13 

 (d) Neither any members of, or participants in, the Depositary (collectively, the
“Agent Members”) nor any other Persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Note registered in the name of the Depositary or any nominee thereof, or under any
such Global Note, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and holder of such Global Note for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such
nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a holder
of any Note. 
 The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The
Depository Trust Company to act as Depositary with respect to the Notes in global form. Initially, the Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with
the Trustee, as custodian for Cede & Co. 
 If at any time the Depositary for a Global Note notifies the Company that
it is unwilling or unable to continue as Depositary for such Note, the Company may appoint a successor Depositary with respect to such Note. If a successor Depositary is not appointed by the Company within ninety (90) days after the Company
receives such notice, the Company will execute, and the Trustee, upon receipt of an Officers’ Certificate for the authentication and delivery of Notes, will authenticate and deliver, Certificated Notes, in aggregate principal amount equal to
the principal amount of such Global Note, in exchange for such Global Note. 
 If a Certificated Note is issued in exchange for
any portion of a Global Note after the close of business at the office or agency where such exchange occurs on any Regular Record Date and before the opening of business at such office or agency on the next succeeding Interest Payment Date, interest
will not be payable on such Interest Payment Date in respect of such Certificated Note, but will be payable on such Interest Payment Date only to the Person to whom interest in respect of such portion of such Global Note is payable in accordance
with the provisions of this Indenture. 
 Certificated Notes issued in exchange for all or a part of a Global Note pursuant to
this Section 2.07 shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. Upon execution and
authentication, the Trustee shall deliver such Certificated Notes to the Persons in whose names such Certificated Notes are so registered. 

  
 14 

 At such time as all interests in a Global Note have been converted, canceled, exchanged for
Certificated Notes, or transferred to a transferee who receives Certificated Notes thereof, such Global Note shall, upon receipt thereof, be canceled by the Trustee in accordance with standing procedures and instructions existing between the
Depositary and the Trustee. At any time prior to such cancellation, if any interest in a Global Note is exchanged for Certificated Notes, converted, repurchased or canceled, or transferred to a transferee who receives Certificated Notes therefor or
any Certificated Note is exchanged or transferred for part of a Global Note, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Trustee, be
appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee to reflect such reduction or increase. 
 Section 2.08. Replacement Notes. If (a) any mutilated Note is surrendered to the Trustee, or (b) the Company, the Trustee and, if applicable, the Authenticating Agent receive evidence to
their satisfaction of the destruction, loss or theft of any Note, and there is delivered to the Company, the Trustee and, if applicable, the Authenticating Agent such Note or indemnity as may be required by them to save each of them harmless, then,
in the absence of notice to the Company, the Trustee or, if applicable, the Authenticating Agent that such Note has been acquired by a bona fide purchaser, the Company shall execute and upon its written request the Trustee or the Authenticating
Agent shall authenticate and deliver, in exchange for any such mutilated Note or in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount, bearing a number not contemporaneously outstanding. 

In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, or is about to be purchased
by the Company pursuant to Article 3 hereof, the Company in its discretion may, instead of issuing a new Note, pay or purchase such Note, as the case may be. 
 Upon the issuance of any new Notes under this Section 2.08, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Trustee and any Authenticating Agent) connected therewith. 
 Every new Note issued pursuant to this Section 2.08 in lieu of any mutilated, destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Company, whether or
not the destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder. 

The provisions of this Section 2.08 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with
respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes. 

  
 15 

 Section 2.09. Outstanding Notes; Determination of Holders’ Action. Notes
outstanding at any time are all the Notes authenticated by the Trustee except for those cancelled by it or delivered to it for cancellation, those paid pursuant to Section 2.08 and those described in this Section 2.09 as not outstanding. A
Note does not cease to be outstanding because the Company or an Affiliate thereof holds the Note; provided, however, that in determining whether the Holders of the requisite principal amount of the outstanding Notes have given or concurred in any
request, demand, authorization, direction, notice, consent or waiver hereunder, Notes owned by the Company or any other obligor upon the Notes or any Affiliate of the Company or such other obligor shall be disregarded and deemed not to be
outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such request, demand, authorization, direction, notice, consent or waiver, only Notes which a Responsible Officer of the Trustee actually knows to be
so owned shall be so disregarded. Subject to the foregoing, only Notes outstanding at the time of such determination shall be considered in any such determination (including, without limitation, determinations pursuant to Articles 6 and 9).

 If a Note is replaced pursuant to Section 2.08, it ceases to be outstanding unless the Trustee receives proof
satisfactory to it that the replaced Note is held by a bona fide purchaser. 
 If the Paying Agent holds, in accordance with
this Indenture, on the Business Day following the Change of Control Purchase Date, or on Stated Maturity, money or securities, if permitted hereunder, sufficient to pay Notes payable on that date, then immediately after such Change of Control
Purchase Date or Stated Maturity, as the case may be, such Notes shall cease to be outstanding and interest on such Notes shall cease to accrue. 
 If a Note is converted in accordance with Article 10, then from and after the time of conversion on the conversion date, such Note shall cease to be outstanding and interest shall cease to accrue on such
Note. 
 Section 2.10. Temporary Notes. Pending the preparation of definitive Notes, the Company may execute, and upon a
Company Order the Trustee shall authenticate and deliver, temporary Notes which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Notes in lieu of
which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Notes may determine, as conclusively evidenced by their execution of such Notes. 

If temporary Notes are issued, the Company will cause definitive Notes to be prepared without unreasonable delay. After the preparation
of definitive Notes, the temporary Notes shall be exchangeable for definitive Notes upon surrender of the temporary Notes at the office or agency of the Company designated for such purpose pursuant to Section 2.04, without charge to the Holder.
Upon surrender for cancellation of any one or more temporary Notes the Company shall execute and the Trustee or an 

  
 16 

 
Authenticating Agent shall authenticate and deliver in exchange therefor a like principal amount of definitive Notes of authorized denominations. Until so exchanged the temporary Notes shall in
all respects be entitled to the same benefits under this Indenture as definitive Notes. 
 Section 2.11. Cancellation.
All Notes surrendered for payment, purchase by the Company pursuant to Article 3, conversion or registration of transfer or exchange shall, if surrendered to any person other than the Trustee, be delivered to the Trustee and shall be promptly
cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Notes so delivered shall be
promptly cancelled by the Trustee. The Company may not issue new Notes to replace Notes it has paid or delivered to the Trustee for cancellation or that any Holder has converted pursuant to Article 10. No Notes shall be authenticated in lieu of or
in exchange for any Notes cancelled as provided in this Section 2.11, except as expressly permitted by this Indenture. All cancelled Notes held by the Trustee shall be disposed of by the Trustee in its customary manner. 

Section 2.12. 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 as the owner of such Note for the purpose of receiving payment of principal of the Note or the payment of any Change of Control Purchase Price in
respect thereof, and interest thereon, for the purpose of conversion and for all other purposes whatsoever, whether or not such Note be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by
notice to the contrary. 
 Section 2.13. CUSIP Numbers. The Company in issuing the Notes may use “CUSIP”
numbers (if then generally in use). No representation is made as to the correctness of such CUSIP numbers and reliance may be placed only on the other identification numbers printed on the Notes. The Company will promptly notify the Trustee of any
change in the CUSIP numbers. 
 Section 2.14. Default Interest. If the Company defaults in a payment of interest on the
Notes, it shall pay, or shall deposit with the Paying Agent money in immediately available funds sufficient to pay, the defaulted interest, plus (to the extent lawful) any interest payable on the defaulted interest, to the Persons who are Holders on
a subsequent special record date. A special record date, as used in this Section 2.14 with respect to the payment of any defaulted interest, shall mean the 15th day next preceding the date fixed by the Company for the payment of defaulted
interest, whether or not such day is a Business Day. At least 15 days before the subsequent special record date, the Company shall mail to each Holder and to the Trustee a notice that states the subsequent special record date, the payment date and
the amount of defaulted interest to be paid. 

  
 17 

 ARTICLE 3 
 REDEMPTION AND REPURCHASE UPON A CHANGE OF CONTROL 

Section 3.01. Company’s Right to Redeem. Prior to Stated Maturity, the Company, at its option, may redeem the Notes, in whole
or in part, in accordance with the provisions of Section 3.02, Section 3.03 and Section 3.04 on the Redemption Date for a redemption price (the “Redemption Price”) in cash equal to 100% of the principal amount of the
Notes plus any accrued and unpaid interest, on the Notes redeemed to but excluding the Redemption Date if the Closing Price of the Common Stock has exceeded 130% of the Conversion Price for at least 20 Trading Days in any consecutive 30 Trading Day
period. In addition, if on any Interest Payment Date, the aggregate principal amount of the Notes outstanding is less than 15% of the aggregate principal amount of Notes outstanding after the Issue Date, the Company, at its option, may redeem the
Notes, in whole but not in part, in accordance with the provisions of Section 3.02, Section 3.03 and Section 3.04 on the Redemption Date for a Redemption Price in cash equal to 100% of the principal amount of the Notes plus any
accrued and unpaid Interest, on the Notes to but not including the Redemption Date. The Company will make an additional payment equal to the total value of the aggregate amount of the interest otherwise payable on the Notes from the last day through
which interest was paid on the Notes through the Redemption Date. 
 Section 3.02. Notice of Optional Redemption;
Selection of Notes.  
 (a) In case the Company shall desire to exercise the right to redeem all or, as the case may be, any
part of the Notes pursuant to Section 3.01, it shall fix a date for redemption (the “Redemption Date”) and it or, at its written request (which request must include the information listed in Section 3.02(b) and be received
by the Trustee not fewer than thirty-five (35) days prior (or such shorter period of time as may be acceptable to the Trustee) to the Redemption Date), the Trustee in the name of and at the expense of the Company, shall mail or cause to be
mailed a notice of such redemption (a “Redemption Notice”) not fewer than twenty (20) nor more than sixty (60) days prior to the Redemption Date to each holder of Notes so to be redeemed as a whole or in part at its last
address as the same appears on the Note Register; provided that if the Company shall give such notice, it shall also give written notice of the Redemption Date to the Trustee. Such mailing shall be by first class mail. The notice, if mailed
in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not the holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to the holder of any Note designated
for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. Concurrently with the mailing of any such Redemption Notice, the Company shall issue a press release announcing such
redemption, the form and content of which press release shall be determined by the Company in its sole discretion. The failure to issue any such press release or any defect therein shall not affect the validity of the Redemption Notice or any of the
proceedings for the redemption of any Note called for redemption.

 (b) Each such Redemption Notice shall specify the aggregate principal amount of Notes to be
redeemed, the CUSIP, ISIN or similar number or numbers of the Notes being redeemed, the Redemption Date (which shall be a Business Day), the Redemption Price at which Notes are to be redeemed, the place or places of payment, that payment will be
made upon presentation and surrender of such Notes, that Interest accrued and unpaid up to but not including the Redemption Date will be paid as specified in said notice, and that on and after said date Interest thereon or on the portion thereof to
be redeemed will cease to accrue. Such notice shall also state the current Conversion Rate and the date on which the right to convert such Notes or portions thereof into Common Shares will expire. If fewer than all the Notes are to be redeemed, the
Redemption Notice shall identify the Notes to be redeemed (including CUSIP, ISIN or similar number or numbers, if any). In case any Note is to be redeemed in part only, the Redemption Notice shall state the portion of the principal amount thereof to
be redeemed and shall state that, on and after the Redemption Date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion thereof will be issued. 

(c) On or prior to the Redemption Date specified in the Redemption Notice given as provided in this Section 3.02, the Company will
deposit with the Trustee or with one or more Paying Agents an amount of money in immediately available funds sufficient to redeem on the Redemption Date all the Notes (or portions thereof) so called for redemption (other than those theretofore
surrendered for conversion into Common Shares) at the appropriate Redemption Price; provided that if such payment is made on the Redemption Date it must be received by the Trustee or Paying Agent, as the case may be, by 10:00 a.m., New York
City time, on such date. The Company shall be entitled to retain any interest, yield or gain on amounts deposited with the Trustee or any Paying Agent pursuant to this Section 3.02(c) in excess of amounts required hereunder to pay the
Redemption Price. Subject to the last sentence of Section 7.05, if any Note called for redemption is converted pursuant hereto prior to such Redemption Date, any money deposited with the Trustee or any Paying Agent or so segregated and held in
trust for the redemption of such Note shall be paid to the Company upon its written request, or, if then held by the Company, shall be discharged from such trust. Whenever any Notes are to be redeemed, the Company will give the Trustee written
notice in the form of an Officers’ Certificate not fewer than thirty-five (35) days (or such shorter period of time as may be acceptable to the Trustee) prior to the Redemption Date as to the aggregate principal amount of Notes to be
redeemed. 
 (d) If the Company opts to redeem less than all of the Outstanding Notes, the Trustee shall select or cause to be
selected the Notes or portions thereof of the Global Note or the Notes in certificated form to be redeemed (in principal amounts of $1,000 or integral multiples thereof) by lot, on a pro rata basis or by another method the Trustee deems fair and
appropriate. If any Note selected for partial redemption is submitted for conversion in part after such selection, the portion of such Note submitted for conversion shall be deemed (so far as may be possible) to be from the portion selected for
redemption. The Notes (or portions thereof) so selected shall be deemed duly selected for redemption for all purposes hereof, notwithstanding that any such Note is submitted for conversion in part before the mailing of the Redemption Notice.

  
 19 

 Upon any redemption of less than all of the Outstanding Notes, the Company and the Trustee
may (but need not), solely for purposes of determining the pro rata allocation among such Notes as are unconverted and Outstanding at the time of redemption, treat as Outstanding any Notes surrendered for conversion during the period of fifteen
(15) days next preceding the mailing of a Redemption Notice and may (but need not) treat as Outstanding any Note authenticated and delivered during such period in exchange for the unconverted portion of any Note converted in part during such
period. 
 Section 3.03. Payment of Notes Called for Redemption by the Company. If notice of redemption has been given as
provided in Section 3.02(a), the Notes or portion of Notes with respect to which such notice has been given shall, unless converted into Common Shares pursuant to the terms hereof, become due and payable on the Redemption Date and at the place
or places stated in such notice at the applicable Redemption Price, unless the Company shall default in the payment of the Redemption Price. Interest on the Notes or portion of Notes so called for redemption shall cease to accrue and after the close
of business on the second Business Day immediately preceding the Redemption Date (unless the Company shall default in the payment of the Redemption Price), such Notes shall cease to be convertible into Common Shares and, except as provided in
Section 7.05, to be entitled to any benefit or security under this Indenture, and the holders thereof shall have no right in respect of such Notes except the right to receive the Redemption Price thereof. On presentation and surrender of such
Notes at a place of payment in said notice specified, the said Notes or the specified portions thereof shall be paid and redeemed by the Company at the applicable Redemption Price; provided that if the applicable Redemption Date is an
Interest Payment Date, the Interest payable on such Interest Payment Date shall be paid on such Interest Payment Date to the holders of record of such Notes on the applicable record date instead of the holders surrendering such Notes for redemption
on such date. 
 Upon presentation of any Note redeemed in part only, the Company shall execute and the Trustee shall
authenticate and make available for delivery to the holder thereof, at the expense of the Company, a new Note or Notes, of authorized denominations, in principal amount equal to the unredeemed portion of the Note or Notes so presented. 

Notwithstanding the foregoing, the Trustee shall not redeem any Notes or mail any Redemption Notices during the continuance of a default
in payment of Interest on the Notes. If any Note called for redemption shall not be so paid upon surrender thereof for redemption, the principal shall, until paid or duly provided for, continue to bear interest at the rate borne by the Note,
compounded semi-annually, and such Note shall remain convertible into Common Shares, cash or a combination of cash and Common Shares until the principal and Interest shall have been paid or duly provided for. The Company will notify all of the
holders if the Company redeems any of the Notes. 

  
 20 

 Section 3.04. Conversion Arrangement on Call for Redemption. In connection with any
redemption of Notes, the Company may arrange for the purchase and conversion of any Notes by an agreement with one or more investment banks or other purchasers to purchase such Notes by paying to the Trustee in trust for the Noteholders, on or
before the date fixed for redemption, an amount not less than the applicable redemption price, together with Interest accrued and unpaid to, but excluding, the date fixed for redemption, of such Notes. Notwithstanding anything to the contrary
contained in this Article 3, the obligation of the Company to pay the redemption price of such Notes, together with Interest accrued and unpaid to, but excluding, the date fixed for redemption, shall be deemed to be satisfied and discharged to the
extent such amount is so paid by such purchasers. If such an agreement is entered into, a copy of which will be filed with the Trustee prior to the date fixed for redemption, any Notes not duly surrendered for conversion by the holders thereof may,
at the option of the Company, be deemed, to the fullest extent permitted by law, acquired by such purchasers from such holders and surrendered by such purchasers for conversion, all as of immediately prior to the close of business on the date fixed
for redemption (and the right to convert any such Notes shall be extended through such time), subject to payment of the above amount as aforesaid. At the direction of the Company, the Trustee shall hold and dispose of any such amount paid to it in
the same manner as it would monies deposited with it by the Company for the redemption of Notes. Without the Trustee’s prior written consent, no arrangement between the Company and such purchasers for the purchase and conversion of any Notes
shall increase or otherwise affect any of the powers, duties, responsibilities or obligations of the Trustee as set forth in this Indenture. 
 Section 3.05. Purchase of Notes at Option of the Holder Upon Change of Control. (a) If there shall have occurred a Change of Control, all or any portion of the Notes of any Holder equal to
$1,000 or a whole multiple of $1,000, shall be repurchased by the Company, at the option of such Holder, at a repurchase price equal to 100% of the aggregate principal amount of the Notes to be repurchased, together with accrued and unpaid interest,
if any, to, but excluding, the purchase date (the “Change of Control Purchase Price”), on the date (the “Change of Control Purchase Date”) that is 45 days after the date the Company delivered the notice required
under Section 3.05(c) (or if such 45th day is not a Business Day, the next succeeding Business Day); provided, however, that if the Change of Control Purchase Date is after a Regular Record Date but on or prior to the corresponding Interest
Payment Date, the accrued and unpaid interest becoming due on such Interest Payment Date shall be payable to the Holders of such Notes, or one or more predecessor Notes, registered as such on the relevant Regular Record Date according to their
terms. 
 The Company shall pay, at its option, the Change of Control Purchase Price in cash or shares of its Common Stock. If
the Company pays the Change of Control Purchase Price in shares of its Common Stock, the value of its Common Stock to be delivered in respect of the Change of Control Purchase Price shall be deemed to be equal to the average Closing Price per share
over the ten Trading Day period ending on the Trading Day immediately preceding the Change of Control Purchase Date. The 

  
 21 

 
Company may pay the Change of Control Purchase Price in shares of its Common Stock only if the information necessary to calculate the Closing Price per share is published in a daily newspaper of
general circulation or by other appropriate means. 
 Whenever in this Indenture (including Sections 2.01, 6.01(a) and 6.07
hereof) or Exhibit A annexed hereto there is a reference, in any context, to the principal of any Note as of any time, such reference shall be deemed to include reference to the Change of Control Purchase Price in respect to such Note to the extent
that such Change of Control Purchase Price is, was or would be so payable at such time, and express mention of the Change of Control Purchase Price in any provision of this Indenture shall not be construed as excluding the Change of Control Purchase
Price in those provisions of this Indenture when such express mention is not made. 
 A “Change of Control” of
the Company shall be deemed to have occurred at such time after the original issuance of the Notes as any of the following events shall occur: 
 (i) any “person” or “group” (as such terms are used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), acquires the
beneficial ownership (as defined in Rules 13d-3 and 13d-5 under the Exchange Act, except that such Person shall be deemed to have “beneficial ownership” of all securities that such Person has the right to acquire, whether such right
is exercisable immediately or only after the passage of time), directly or indirectly, through a purchase, merger or other acquisition transaction, of 50% or more of the total voting power of the total outstanding Voting Stock of the Company other
than an acquisition by the Company, any of its Subsidiaries or any employee benefit plans of the Company; or 

(ii) the Company consolidates with, or merges with or into, another Person or conveys, transfers, leases or otherwise
disposes of all or substantially all of its assets to any Person, or any Person consolidates with or merges with or into the Company other than: 
 (A) any transaction (1) that does not result in any reclassification, conversion, exchange or cancellation of outstanding shares of the Capital Stock of the Company and (2) pursuant to which
holders of the Capital Stock of the Company immediately prior to the transaction are entitled to exercise, directly or indirectly, 50% or more of the total voting power of all shares of the Capital Stock of the Company entitled to vote generally in
the election of directors of the continuing or surviving person immediately after the transaction; 
 (B) any
merger for the purpose of changing the Company’s jurisdiction of incorporation and resulting in a reclassification, conversion or exchange of outstanding shares of common stock solely into shares of common stock of the surviving entity; or

  
 22 

 (C) all of the consideration for the Common Stock (excluding cash payments
for fractional shares and cash payments made in respect of dissenters’ appraisal rights) in the transaction or transactions constituting the Change of Control consists of common stock traded on a United States national securities exchange or
quoted on the Nasdaq National Market, or which will be so traded or quoted when issued or exchanged in connection with the Change of Control, and as a result of such transaction or transactions the Notes become convertible solely into such common
stock, or 
 (iii) during any consecutive two-year period, individuals who at the beginning of that two-year
period constituted the Board of Directors (together with any new directors whose election to the Board of Directors, or whose nomination for election by the stockholders of the Company, was approved by a vote of a majority of the directors then
still in office who were either directors at the beginning of such period or whose election or nomination for election were previously so approved) cease for any reason to constitute a majority of the Board of Directors then in office; or

 (iv) the stockholders of the Company pass a special resolution approving a plan of liquidation or dissolution
and no additional approvals of the Company’s stockholders are required under applicable law to cause a liquidation or dissolution. 
 Beneficial ownership will be determined in accordance with Rule 13d-3 promulgated by the SEC under the Exchange Act. The term “person” includes any syndicate or group that would be deemed a
“person” under Section 13(d)(3) of the Exchange Act. 
 (b) The following are conditions to the Company’s
election to pay for the Change of Control Purchase Price in Common Stock: 
 (i) The shares of Common Stock to be
issued upon repurchase of Notes hereunder: 
 (A) shall not require registration under any federal securities law
before such shares may be freely transferable without being subject to any transfer restrictions under the Securities Act upon repurchase or, if such registration is required, such registration shall be completed and shall become effective prior to
the Change of Control Purchase Date; and 

  
 23 

 (B) shall not require registration with, or approval of, any governmental
authority under any state law or any other federal law before shares may be validly issued or delivered upon repurchase or if such registration is required or such approval must be obtained, such registration shall be completed or such approval
shall be obtained prior to the Change of Control Purchase Date. 
 (ii) The shares of Common Stock to be listed
upon repurchase of Notes hereunder are, or shall have been, approved for listing on the Nasdaq National Market or the New York Stock Exchange or listed on another national securities exchange, in any case, prior to the Change of Control Purchase
Date. 
 (iii) All shares of Common Stock which may be issued upon repurchase of Notes will be issued out of the
Company’s authorized but unissued Common Stock and will, upon issue, be duly and validly issued and fully paid and nonassessable and free of any preemptive or similar rights. 

(iv) If any of the conditions set forth in clauses (i) through (iii) of this Section 3.05(b) are not
satisfied in accordance with the terms thereof, the Change of Control Purchase Price shall be paid by the Company only in cash. The Company may not change the form of consideration to be paid with respect to the Change of Control Purchase Price once
it has given notice set forth in Section 3.05(c) to Holders, except as described in the immediately preceding sentence. 

(c) Prior to or on the 30th day after the occurrence of a Change of Control, the Company, or, at the written request and expense of the
Company prior to or on the 30th day after such occurrence, the Trustee, shall give to all Holders, in the manner provided in Section 11.02 hereof, notice of the occurrence of the Change of Control and of the purchase right set forth herein
arising as a result thereof. The Company shall also deliver a copy of such notice of a purchase right to the Trustee. The notice shall include a form of Change of Control Purchase Notice (as defined in Section 3.05(d)) to be completed by the
Holder and shall state: 
 (1) briefly, the events causing a Change of Control and the date of such Change of
Control; 
 (2) the date by which the Change of Control Purchase Notice pursuant to this Section 3.05 must
be given; 
 (3) the Change of Control Purchase Date; 

(4) the Change of Control Purchase Price and whether the Change of Control Purchase Price will be payable in cash or
Common Stock; 
 (5) the name and address of the Paying Agent and the Conversion Agent; 

  
 24 

 (6) that Notes as to which a Change of Control Purchase Notice has been
given may be converted pursuant to Article 10 hereof only if the Change of Control Purchase Notice has been withdrawn in accordance with the terms of this Indenture; 

(7) that Notes must be surrendered to the Paying Agent to collect payment; 

(8) that the Change of Control Purchase Price for any Note as to which a Change of Control Purchase Notice has been duly
given and not withdrawn will be paid promptly following the later of the Change of Control Purchase Date and the time of surrender of such Note as described in (7) above; 

(9) briefly, the procedures the Holder must follow to exercise rights under this Section 3.05; 

(10) briefly, the conversion rights of the Notes, including the Conversion Rate and any adjustments thereto; 

(11) the procedures for withdrawing a Change of Control Purchase Notice; and 

(12) the CUSIP number of the Notes. 
 (d) A Holder may exercise its rights specified in this Section 3.05 upon delivery of a written notice of purchase (“Change of Control Purchase Notice”) to the Paying Agent prior to
the Change of Control Purchase Date, stating: 
 (1) the certificate number of the Note, if any, which the
Holder will deliver to be purchased or the appropriate Depositary procedures if the Notes are not in certificated form; 
 (2) the portion of the principal amount of the Note which the Holder will deliver to be purchased, which portion must be $1,000 or any whole multiple thereof; and 

(3) that such Note shall be purchased pursuant to the terms and conditions specified in paragraph 5 on the reverse side
of the Notes and in this Indenture. 
 If the Notes are not in certificated form, a Holder’s Change of Control Purchase
must comply with the appropriate DTC procedures. 

  
 25 

 The delivery of such Note to the Paying Agent prior to the Change of Control Purchase Date
(together with all necessary endorsements) at the offices of the Paying Agent shall be a condition to the receipt by the Holder of the Change of Control Purchase Price therefor; provided, however, that such Change of Control Purchase Price shall be
so paid pursuant to this Section 3.05 only if the Note so delivered to the Paying Agent shall conform in all respects to the description thereof set forth in the related Change of Control Purchase Notice. 

The Company shall purchase from the Holder thereof, pursuant to this Section 3.05, a portion of a Note so delivered for purchase if
the principal amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to the purchase of all of a Note also apply to the purchase of such portion of such Note. 

Any purchase by the Company contemplated pursuant to the provisions of this Section 3.05 shall be consummated by the delivery of the
consideration to be received by the Holder promptly following the later of the Change of Control Purchase Date and the time of delivery of the Note to the Paying Agent in accordance with this Section 3.05. 

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Change of Control Purchase Notice
contemplated by this Section 3.05 shall have the right to withdraw such Change of Control Purchase Notice at any time prior to the close of business on the Business Day prior to the Change of Control Purchase Date by delivery of a written
notice of withdrawal to the Paying Agent in accordance with Section 3.06. 
 The Paying Agent shall promptly notify the
Company of the receipt by it of any Change of Control Purchase Notice or written withdrawal thereof. 
 Section 3.06. Effect
of Change of Control Purchase Notice. Upon receipt by the Paying Agent of the Change of Control Purchase Notice specified in Section 3.05(d), the Holder of the Note in respect of which such Change of Control Purchase Notice was given shall
(unless such Change of Control Purchase Notice is withdrawn as specified in the following two paragraphs) thereafter be entitled to receive solely the Change of Control Purchase Price with respect to such Note. Such Purchase Price shall be paid to
such Holder, subject to receipt of consideration for the Notes by the Paying Agent, promptly following the later of (x) the Change of Control Purchase Date with respect to such Note (provided the conditions in Section 3.05(d), as the case
may be, have been satisfied) or (y) the time of delivery of such Note to the Paying Agent by the Holder thereof in the manner required by Section 3.05(d), as the case may be. Notes in respect of which a Change of Control Purchase Notice
has been given by the Holder thereof may not be converted pursuant to Article 10 hereof on or after the date of the delivery of such Change of Control Purchase Notice unless such Change of Control Purchase Notice has first been validly withdrawn as
specified in the following two paragraphs. 

  
 26 

 A Change of Control Purchase Notice may be withdrawn by means of a written notice of
withdrawal delivered to the office of the Paying Agent in accordance with the Change of Control Purchase Notice at any time prior to the close of business on the Business Day immediately preceding the Change of Control Purchase Date specifying:

 (1) the certificate number of the Note in respect of which such notice of withdrawal is being submitted or,
if not in certificated form, the applicable Depositary procedures, 
 (2) the principal amount of the Note with
respect to which such notice of withdrawal is being submitted, and 
 (3) the principal amount, if any, of such
Note which remains subject to the original Change of Control Purchase Notice and which has been or will be delivered for purchase by the Company. 
 There shall be no purchase of any Notes pursuant to Section 3.05 if there has occurred (prior to, on or after, as the case may be, the giving, by the Holders of such Notes, of the required Change of
Control Purchase Notice) and is continuing an Event of Default (other than a default in the payment of the Change of Control Purchase Price with respect to such Notes). The Paying Agent will promptly return to the respective Holders thereof any
Notes (x) with respect to which a Change of Control Purchase Notice has been withdrawn in compliance with this Indenture, or (y) held by it during the continuance of an Event of Default (other than a default in the payment of the Change of
Control Purchase Price with respect to such Notes) in which case, upon such return, the Change of Control Purchase Notice with respect thereto shall be deemed to have been withdrawn. 

Section 3.07. Deposit of Change of Control Purchase Price. Prior to 10:00 a.m. (New York City time) on the Change of Control
Purchase Date, the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided in
Section 2.05) an amount of cash (in immediately available funds if deposited on such Business Day) or Common Stock sufficient to pay the aggregate Change of Control Purchase Price of all the Notes or portions thereof which are to be purchased
as of the Change of Control Purchase Date. 
 If the Trustee or other Paying Agent appointed by the Company, or the Company or
an Affiliate of the Company, if it or such Affiliate is acting as the Paying Agent, holds cash or shares of Common Stock sufficient to pay the Change of Control Purchase Price of all the Notes or portions thereof that are to be purchased as of the
Change of Control Purchase Date, then immediately after the Change of Control Purchase Date (i) such Notes will cease to be outstanding, (ii) interest on such Notes will cease to accrue and (iii) all other rights of the holders of
such Notes will terminate other than the right to 

  
 27 

 
receive the Change of Control Purchase Price upon delivery of the Notes, whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying
Agent. 
 Section 3.08. Notes Purchased in Part. Any Note which is to be purchased only in part shall be surrendered at
the office of the Paying Agent (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s
attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Note, without service charge, a new Note or Notes, of any authorized denomination as requested by such Holder in
aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Note so surrendered which is not purchased. 
 Section 3.09. Covenant to Comply with Securities Laws upon Purchase of Notes. In connection with any offer to purchase or purchase of Notes under Section 3.05 hereof (provided that such offer
or purchase constitutes an “issuer tender offer” for purposes of Rule 13e-4 (which term, as used herein, includes any successor provision thereto) under the Exchange Act at the time of such offer or purchase), the Company shall
(i) comply with Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act which may then be applicable, (ii) file the related Schedule TO (or any successor schedule, form or report) or any other schedule required under
the Exchange Act, and (iii) otherwise comply with all federal and state securities laws so as to permit the rights and obligations under Section 3.05 to be exercised in the time and in the manner specified in Section 3.05. 

Section 3.10. Repayment to the Company. The Trustee and the Paying Agent shall return to the Company any cash or shares of Common
Stock that remains unclaimed as provided in paragraph 9 of the Notes, together with interest or dividends, if any, thereon, held by them for the payment of the Change of Control Purchase Price; provided, however, that to the extent that the
aggregate amount of cash or shares of Common Stock deposited by the Company pursuant to Section 3.07 exceeds the aggregate Change of Control Purchase Price of the Notes, or portions thereof which the Company is obligated to purchase as of the
Change of Control Purchase Date then promptly after the Business Day following the Change of Control Purchase Date the Trustee shall return any such excess to the Company together with interest or dividends, if any, thereon. 

ARTICLE 4 

COVENANTS 
 Section 4.01. Payment of Principal, Interest on the Notes. The Company will duly and punctually pay the principal of, and interest in respect of, the Notes in accordance with the terms of the Notes
and this Indenture. The Company will deposit or 

  
 28 

 
cause to be deposited with the Trustee, no later than the day of the Stated Maturity of any Note or installment of interest, all payments so due. Principal amount, Change of Control Purchase
Price and cash interest shall be considered paid on the applicable date due if on such date (or, in the case of a Change of Control Purchase Price on the Business Day following the applicable Change of Control Purchase Date) the Trustee or the
Paying Agent holds, in accordance with this Indenture, money or Notes, if permitted hereunder, sufficient to pay all such amounts then due. 
 The Company shall, to the extent permitted by law, pay cash interest on overdue amounts at the rate per annum set forth in paragraph 1 of the Notes, compounded semiannually, which interest shall accrue
from the date such overdue amount was originally due to the date payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be payable on demand. 

Section 4.02. Reports by the Company. The Company shall file with the Trustee (and the SEC after the Indenture becomes qualified
under the TIA), and transmit to holders of Notes, such information, documents and other reports and such summaries thereof, as may be required pursuant to the TIA at the times and in the manner provided pursuant to the TIA, whether or not the Notes
are governed by the TIA; provided, however, that any such information, documents or reports required to be filed with the SEC pursuant to Section 13 or 15(d) of the Exchange Act shall be filed with the Trustee within fifteen (15) days
after the same is so required to be filed with the SEC. Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any
information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

 Section 4.03. Compliance Certificate. The Company shall deliver to the Trustee within 120 days after the end of each
fiscal year of the Company (beginning with the fiscal year ending on December 31, 2012) an Officers’ Certificate, stating whether or not to the best knowledge of the signers thereof the Company is in default in the performance and
observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and if the Company shall be in default, specifying all such defaults and the nature and
status thereof of which they may have knowledge. 
 Section 4.04. Further Instruments and Acts. Upon request of the
Trustee, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture. 

Section 4.05. Maintenance of Office or Agency. The Company will maintain in the Borough of Manhattan, the City of New York, an
office or agency of the Trustee, Note Registrar, Paying Agent and Conversion Agent where Notes may be presented or 

  
 29 

 
surrendered for payment, where Notes may be surrendered for registration of transfer, exchange, purchase or conversion and where notices and demands to or upon the Company in respect of the Notes
and this Indenture may be served. The Corporate Trust Office and each office or agency of the Trustee in the Borough of Manhattan, the City of New York, shall initially be one such office or agency for all of the aforesaid purposes. The Company
shall give prompt written notice to the Trustee of the location, and of any change in the location, of any such office or agency (other than a change in the location of the office of the Trustee). If at any time the Company shall fail to maintain
any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 11.02. 

The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered
for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of
Manhattan, the City of New York, for such purposes. 
 Section 4.06. Delivery of Certain Information. At any time when
the Company is not subject to Section 13 or 15(d) of the Exchange Act, upon the request of a holder or any beneficial holder of Notes or shares of Common Stock issued upon conversion thereof, the Company will promptly furnish or cause to be
furnished Rule 144A Information (as defined below) to such Holder or any beneficial holder of Notes or holder of shares of Common Stock issued upon conversion of Notes, or to a prospective purchaser of any such security designated by any such
holder, as the case may be, to the extent required to permit compliance by such Holder or holder with Rule 144A under the Securities Act in connection with the resale of any such security. “Rule 144A Information” shall be such
information as is specified pursuant to Rule 144A(d)(4) under the Securities Act. 
 Section 4.07. Existence. Subject to
Article 5, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its existence and rights (charter and statutory); provided, however, that the Company shall not be required to preserve any such
right if the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Noteholders. 

Section 4.08. Maintenance of Properties. The Company will cause all properties used or useful in the conduct of its business or
the business of any Significant Subsidiary to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and
improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing

  
 30 

 
in this Section shall prevent the Company from discontinuing the operation or maintenance of any of such properties if such discontinuance is, in the judgment of the Company, desirable in the
conduct of its business or the business of any Significant Subsidiary and not disadvantageous in any material respect to the Noteholders. 
 Section 4.09. Payment of Taxes and Other Claims. The Company will pay or discharge, or cause to be paid or discharged, before the same may become delinquent, (i) all taxes, assessments and
governmental charges levied or imposed upon the Company or any Significant Subsidiary or upon the income, profits or property of the Company or any Significant Subsidiary, (ii) all claims for labor, materials and supplies which, if unpaid,
might by law become a Lien or charge upon the property of the Company or any Significant Subsidiary and (iii) all stamps and other duties, if any, which may be imposed by the United States or any political subdivision thereof or therein in
connection with the issuance, transfer, exchange or conversion of any Notes or with respect to this Indenture; provided, however, that, in the case of clauses (i) and (ii), the Company shall not be required to pay or discharge or cause to be
paid or discharged any such tax, assessment, charge or claim (A) if the failure to do so will not, in the aggregate, have a material adverse impact on the Company, or (B) if the amount, applicability or validity is being contested in good
faith by appropriate proceedings.

the applicable grace period, if any, after the final scheduled payment date for such payment with respect to any indebtedness for borrowed money in an aggregate amount in excess of $10 million or (ii) indebtedness for borrowed money of the
Company or any Significant Subsidiary in an aggregate amount in excess of $10 million shall have been accelerated or otherwise declared due and payable, or required to be prepaid or repurchased (other than by regularly scheduled required prepayment)
prior to the scheduled maturity thereof as a result of a default with respect to such indebtedness, in either case without such indebtedness referred to in subclause (i) or (ii) of this clause (f) having been discharged, cured,

(i) is for relief against the Company or any Significant Subsidiary or any Subsidiaries of the Company which in the

Subsidiary or any Subsidiaries of the Company which in the aggregate would constitute a Significant Subsidiary; 
 and the order or decree
remains unstayed and in effect for 60 days. 
 For purposes of Sections 6.01(g) and 6.01(h) above: 

“Bankruptcy Law” means Title 11, United States Code, or any similar federal or state law for the relief
of debtors. 
 “Custodian” means any receiver, trustee, assignee, liquidator, custodian or
similar official under any Bankruptcy Law. 
 A Default under clause (e) or (f) above is not an Event of Default until
the Trustee notifies the Company, or the Holders of at least 25% in aggregate principal amount of the Notes at the time outstanding notify the Company and the Trustee, of the Default and the Company does not cure such Default (and such Default is
not waived) within the time specified in clause (e) or (f) above after actual receipt of such notice. Any such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of
Default.” 
 The Company shall deliver to the Trustee, within five Business Days of becoming aware of the occurrence of
an Event of Default, written notice thereof. In addition, the Company shall deliver to the Trustee, within 30 days after they become aware of the occurrence thereof, written notice of any event which with the lapse of time would become an Event of
Default under clause (e) above, its status and what action the Company is taking or proposes to take with respect thereto. 

Section 6.02. Acceleration. If an Event of Default (other than an Event of Default specified in Section 6.01(g) or 6.01(h))
occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Notes at the time outstanding by notice to the Company and the Trustee, may declare the Notes due and payable at
their principal amount together with accrued interest. Upon a declaration of acceleration, such principal and accrued and unpaid interest to the date of payment shall be immediately due and payable. If an Event of Default is cured prior to any such
declaration by the Trustee or the Holders, the Trustee and the Holders shall not be entitled to declare the Notes due and payable as provided herein as a result of such cured Event of Default and any such cured Event of Default shall be deemed
waived by the Holders and the Trustee. 
 If an Event of Default specified in Sections 6.01(g) or 6.01(h) above occurs and is
continuing, then the principal and the accrued interest on all the Notes shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Noteholders. 

  
 34 

 The Holders of a majority in aggregate principal amount of the Notes at the time
outstanding, by notice to the Trustee (and without notice to any other Noteholder) may rescind or annul an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have
been cured or waived except nonpayment of the principal and any accrued cash interest that have become due solely as a result of acceleration and if all amounts due to the Trustee under Section 7.06 have been paid. No such rescission shall
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 the principal of, and any accrued cash interest on, the Notes or to enforce the performance of any provision of the Notes or this Indenture.

 The Trustee may maintain a proceeding even if the Trustee does not possess any of the Notes or produce any of the Notes in
the proceeding. A delay or omission by the Trustee or any Noteholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of, or acquiescence in, the Event of Default. No
remedy is exclusive of any other remedy. All available remedies are cumulative. 
 Section 6.04. Waiver of Past Defaults.
The Holders of a majority in aggregate principal amount of the Notes at the time outstanding, by notice to the Trustee (and without notice to any other Noteholder), may waive an existing Event of Default and its consequences except (1) an
Event of Default described in Section 6.01(a) or 6.01(b) and (2) an Event of Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Noteholder affected. When an Event of Default is
waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Event of Default or impair any consequent right. 
 Section 6.05. Control By Majority. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding may direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or of 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 that the Trustee determines in good faith is
prejudicial to the rights of other Noteholders or would involve the Trustee in personal liability unless the Trustee is offered indemnity satisfactory to it against loss, liability or expense. 

Section 6.06. Limitation On Suits. A Noteholder may not pursue any remedy with respect to this Indenture or the Notes unless:

 (1) the Holder gives to the Trustee written notice stating that an Event of Default is continuing; 

  
 35 

 (2) the Holders of at least 25% in aggregate principal amount of the Notes
at the time outstanding make a written request to the Trustee to pursue the remedy; 
 (3) such Holder or Holders
offer to the Trustee reasonable security or indemnity satisfactory to the Trustee against any loss, liability or expense; 
 (4) the Trustee does not comply with the request within 60 days after receipt of such notice, request and offer of security or indemnity; and 

(5) the Holders of a majority in aggregate principal amount of the Notes at the time outstanding do not give the Trustee a
direction inconsistent with the request during such 60-day period. 
 A Noteholder may not use this Indenture to prejudice the
rights of any other Noteholder or to obtain a preference or priority over any other Noteholder. 
 Section 6.07. Rights of
Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of the principal amount, Change of Control Purchase Price or any accrued cash interest in respect of the Notes held by
such Holder, on or after the respective due dates expressed in the Notes or any Change of Control Purchase Date, and to convert the Notes in accordance with Article 10, or to bring suit for the enforcement of any such payment on or after such
respective dates or the right to convert, shall not be impaired or affected adversely without the consent of such Holder. 

Section 6.08. Collection Suit by Trustee. If an Event of Default described in Section 6.01(a) or 6.01(b) occurs and is
continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount owing with respect to the Notes and the amounts provided for in Section 7.06. 

Section 6.09. Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Notes or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of
whether the principal amount, Change of Control Purchase Price or any accrued cash interest in respect of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have
made any demand on the Company for the payment of any such amount) shall be entitled and empowered, by intervention in such proceeding or otherwise, 
 (a) to file and prove a claim for the whole amount of the principal amount, Change of Control Purchase Price or any accrued cash interest and to file such other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel or any other amounts due the Trustee under Section 7.06) and
of the Holders allowed in such judicial proceeding, and 

  
 36 

 (b) to collect and receive any moneys or other property payable or deliverable on any such
claims and to distribute the same; 
 and any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any such
judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 Section 6.10. Priorities. If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order: 

(1) to the Trustee for amounts due under Section 7.06; 

(2) to Noteholders for amounts due and unpaid on the Notes for the principal amount, Change of Control Purchase Price or
any accrued cash interest as the case may be, ratably, without preference or priority of any kind, according to such amounts due and payable on the Notes; and 
 (3) the balance, if any, to the Company. 
 The Trustee may fix a record date and
payment date for any payment to Noteholders pursuant to this Section 6.10. At least 15 days before such record date, the Trustee shall mail to each Noteholder and the Company a notice that states the record date, the payment date and the amount
to be paid. 
 Section 6.11. 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 (other than the Trustee) in the suit of an undertaking to pay the costs of the suit
in the manner and to the extent provided in the TIA, 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 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in aggregate principal amount of
the Notes at the time outstanding. 

  
 37 

 Section 6.12. Waiver Of Stay, Extension Or Usury Laws. The Company covenants (to the
extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury or other law wherever enacted, now or at any time
hereafter in force, which would prohibit or forgive the Company from paying all or any portion of the principal amount, Change of Control Purchase Price or any accrued cash interest in respect of Notes, or any interest on such amounts, as
contemplated herein, or which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not
hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 

ARTICLE 7 

TRUSTEE 
 Section 7.01. Duties And Responsibilities Of The Trustee; During Default; Prior To Default. The Trustee, prior to the occurrence of an Event of Default hereunder and after the curing or waiving of
all such Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default hereunder has occurred (which has not been cured or waived), the
Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

 No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own
negligent failure to act or its own willful misconduct, except that 
 (a) prior to the occurrence of an Event of Default
hereunder and after the curing or waiving of all such Events of Default which may have occurred: 
 (i) the
duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this
Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 

(ii) in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the
statements and the correctness of the opinions expressed therein, upon any statements, certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such statements, certificates or
opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture; 

  
 38 

 (b) the Trustee shall not be liable for any error of judgment made in good faith by a
Responsible Officer or Responsible Officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; and 
 (c) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders pursuant to Section 6.05 relating to
the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture. 

None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal
financial liability in the performance of any of its duties or in the exercise of any of its rights or powers. 
 Section 7.02.
Certain Rights of the Trustee. Subject to Section 7.01: 
 (a) the Trustee may conclusively rely and shall be fully
protected in acting or refraining from acting upon any resolution, Officers’ Certificate or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, note, coupon, Note or other paper or
document (whether in its original or facsimile form) believed by it to be genuine and to have been signed or presented by the proper party or parties; 
 (b) any request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by an Officers’ Certificate (unless other evidence in respect thereof be herein
specifically prescribed); and any resolution of the Board of Directors may be evidenced to the Trustee by a copy thereof certified by the secretary or an assistant secretary of the Company; 

(c) the Trustee may consult with counsel of its selection and any advice or Opinion of Counsel shall be full and complete authorization
and protection in respect of any action taken, suffered or omitted to be taken by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; 
 (d) the Trustee shall be under no obligation to exercise any of the trusts or powers vested in it by this Indenture with the request, order or direction of any of the Noteholders pursuant to the
provisions of this Indenture, unless such Noteholders shall have offered to the Trustee reasonable security or indemnity satisfactory to it against the costs, expenses and liabilities which might be incurred therein or thereby; 

(e) the Trustee shall not be liable for any action taken or omitted by it in good faith and believed by it to be authorized or within the
discretion, rights or powers conferred upon it by this Indenture; 

  
 39 

 (f) prior to the occurrence of an Event of Default hereunder and after the curing or waiving
of all such Events of Default, the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, appraisal,
bond, debenture, note, coupon, security, or other paper or document unless requested in writing to do so by the Holders of not less than a majority in aggregate principal amount of the Notes then outstanding; provided that, if the payment within a
reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms
of this Indenture, the Trustee may require reasonable indemnity against such expenses or liabilities as a condition to proceeding; the reasonable expenses of every such investigation shall be paid by the Company or, if paid by the Trustee or any
predecessor trustee, shall be repaid by the Company upon demand; 
 (g) the Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through agents or attorneys not regularly in its employ and the Trustee shall not be responsible for any misconduct or negligence on the part of any such agent or attorney appointed
with due care by it hereunder; 
 (h) the Trustee shall not be deemed to have notice of any Default or Event of Default unless a
Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities
and this Indenture; 
 (i) the rights, privileges, protections, immunities and benefits given to the Trustee, including, without
limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder; and 

(j) in no event shall the Trustee be responsible or liable for special, indirect, or consequential loss or damage of any kind whatsoever
(including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 

Section 7.03. Trustee not Responsible for Recitals, Dispositions of Notes or Application of Proceeds Thereof. The recitals
contained herein and in the Notes, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no
representation as to the validity or sufficiency of this Indenture or of the Notes. The Trustee shall not be accountable for the use or application by the Company of any of the Notes or of the proceeds thereof. 

Section 7.04. Trustee and Agents May Hold Notes; Collections, Etc.. The Trustee or any agent of the Company or the Trustee, in its
individual or any other 

  
 40 

 
capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not the Trustee or such agent and, subject to Sections 7.08 and 7.13, if operative, may otherwise
deal with the Company and receive, collect, hold and retain collections from the Company with the same rights it would have if it were not the Trustee or such agent. 
 Section 7.05. Moneys Held by Trustee. Subject to the provisions of Section 8.04 hereof, all moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for
the purposes for which they were received, but need not be segregated from other funds except to the extent required by mandatory provisions of law. Neither the Trustee nor any agent of the Company or the Trustee shall be under any liability for
interest on any moneys received by it hereunder. 
 Section 7.06. Compensation and Indemnification of Trustee and Its Prior
Claim. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, such compensation (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express
trust) to be agreed to in writing by the Trustee and the Company, and the Company covenants and agrees to pay or reimburse the Trustee and each predecessor Trustee upon its request for all expenses, disbursements and advances incurred or made by or
on behalf of it in accordance with any of the provisions of this Indenture (including (i) the reasonable compensation and the expenses and disbursements of its counsel and of all agents and other persons not regularly in its employ and
(ii) interest at the prime rate on any disbursements and advances made by the Trustee and not paid by the Company within 5 days after receipt of an invoice for such disbursement or advance) except any such expense, disbursement or advance as
shall be determined by a court of competent jurisdiction to have been caused by its own negligence or bad faith. The Company also covenants to fully indemnify each of the Trustee, each predecessor Trustee, any Authenticating Agent and any officer,
director, employee or agent of the Trustee, each such predecessor Trustee or any such Authenticating Agent for, and to hold it harmless against, any and all loss, liability, claim, damage or expense (including legal fees and expenses) incurred
without negligence or willful misconduct on its part, arising out of or in connection with the acceptance or administration of this Indenture or the trusts hereunder and its duties hereunder, including the costs and expenses of defending itself
against or investigating any claim of liability in the premises. The obligations of the Company under this Section 7.06 to compensate and indemnify the Trustee, each predecessor Trustee, any Authenticating Agent and any officer, director,
employee or agent of the Trustee, each such predecessor Trustee or any such Authenticating Agent and to pay or reimburse the Trustee and each predecessor Trustee for expenses, disbursements and advances shall constitute additional indebtedness
hereunder and shall survive the satisfaction and discharge of this Indenture. Such additional indebtedness shall be a senior claim to that of the Notes upon all property and funds held or collected by the Trustee as such, except funds held in trust
for the benefit of the Holders of particular Notes, and the Notes are hereby effectively subordinated to such senior claim to such extent. The provisions of this Section 7.06 shall survive the termination of this Indenture and the resignation
or removal of the Trustee. 

  
 41 

 When the Trustee incurs expenses or renders services in connection with an Event of Default, the expenses
(including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any applicable Federal or state bankruptcy, insolvency or other similar law. 

Section 7.07. Right of Trustee to Rely on Officers’ Certificate, Etc.. Subject to Sections 7.01 and 7.02, whenever in the
administration of the trusts of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or suffering or omitting any action hereunder, such matter (unless other evidence in respect
thereof be herein specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate delivered to the Trustee, and such
certificate, in the absence of negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it under the provisions of this Indenture upon the faith thereof. 

Section 7.08. Conflicting Interests. If the Trustee has or shall acquire a conflicting interest within the meaning of the TIA, the
Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the TIA. 
 Section 7.09. Persons Eligible for Appointment as Trustee. The Trustee shall at all times be a corporation or banking association having a combined capital and surplus of at least $50,000,000. If
such corporation or banking association publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then, for the purposes of this Section 7.09, the combined
capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 7.09, the Trustee shall resign immediately in the manner and with the effect specified in Section 7.10. 
 Section 7.10. Resignation and Removal; Appointment of Successor Trustee. (a) The Trustee, or any trustee or trustees hereafter appointed, may at any time resign with respect to one or more or
all series of Notes by giving written notice of resignation to the Company and by mailing notice thereof by first class mail to the Holders of Notes at their last addresses as they shall appear on the Note Register. Upon receiving such notice of
resignation, the Company shall promptly appoint a successor trustee or trustees by written instrument in duplicate, executed by authority of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one
copy to the successor trustee or trustees. If no successor trustee shall have been so appointed and have accepted appointment within 30 days after the mailing of such notice of resignation, 

  
 42 

 
the resigning trustee may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor trustee, or any Noteholder who has been a bona fide
Holder of a Note for at least six months may, subject to the provisions of Section 7.11, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after
such notice, if any, as it may deem proper and prescribe, appoint a successor trustee. 
 (b) In case at any time any of the
following shall occur: 
 (i) the Trustee shall fail to comply with the provisions of Section 7.08 with
respect to any Notes after written request therefor by the Company or by any Noteholder who has been a bona fide Holder of a Note for at least six months; or 
 (ii) the Trustee shall cease to be eligible in accordance with the provisions of Section 7.09 and shall fail to resign after written request therefor by the Company or by any Noteholder; or

 (iii) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent, or a receiver
or liquidator of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation; or 

(iv) the Company shall determine that the Trustee has failed to perform its obligations under this Indenture in any
material respect; 
 then, in any such case, the Company may remove the Trustee and appoint a successor trustee by written instrument, in
duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 7.11, any Noteholder who has been
a bona fide Holder of a Note for at least six months may on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee. Such court may
thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. If no successor trustee shall have been appointed and have accepted appointment within 30 days after a notice of removal
has been given, the removed trustee may petition a court of competent jurisdiction for the appointment of a successor trustee. 

(c) The Holders of a majority in aggregate principal amount of the Notes at the time outstanding may at any time remove the Trustee and
appoint a successor trustee by delivering to the Trustee so removed, to the successor trustee so appointed and to the Company the evidence provided for in Section 1.05 of the action in that regard taken by the Noteholders. 

  
 43 

 (d) Any resignation or removal of the Trustee and any appointment of a successor trustee
pursuant to any of the provisions of this Section 7.10 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.11. 
 Section 7.11. Acceptance of Appointment by Successor Trustee. Any successor trustee appointed as provided in Section 7.10 shall execute and deliver to the Company and to the predecessor
trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with
all rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee hereunder; but, nevertheless, on the written request of the Company or of the successor trustee, upon payment of its charges
then unpaid, the trustee ceasing to act shall pay over to the successor trustee all moneys at the time held by it hereunder and shall execute and deliver an instrument transferring to such successor trustee all such rights, powers, duties and
obligations. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to
act shall, nevertheless, retain a prior claim upon all property or funds held or collected by such trustee to secure any amounts then due it pursuant to the provisions of Section 7.06. 

No successor trustee shall accept appointment as provided in this Section 7.11 unless at the time of such acceptance such successor
trustee shall be qualified under the provisions of Section 7.08 and eligible under the provisions of Section 7.09. 

Upon acceptance of appointment by any successor trustee as provided in this Section 7.11, the Company shall mail notice thereof by
first class mail to the Holders of Notes at their last addresses as they shall appear in the Note Register. If the acceptance of appointment is substantially contemporaneous with the resignation, then the notice called for by the preceding sentence
may be combined with the notice called for by Section 7.10. If the Company fails to mail such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the
expense of the Company. 
 Section 7.12. Merger, Conversion, Consolidation or Succession to Business of Trustee. Any
corporation or banking association into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation or banking association resulting from any merger, conversion or consolidation to which the Trustee shall be
a party, or any corporation or banking association succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder; provided that such corporation or banking association shall be
qualified under the provisions of Section 7.08 and eligible under the provisions of Section 7.09, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary
notwithstanding. In case at the time 

  
 44 

 
such successor to the Trustee shall succeed to the trusts created by this Indenture any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt
the certificate of authentication of any predecessor Trustee or Authenticating Agent and deliver such Notes so authenticated; and, in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or any
Authenticating Agent appointed by such successor Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor Trustee; and in all such cases such certificate shall have the full force and effect
that this Indenture provides for the certificate of authentication of the Trustee; provided that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall
apply only to its successor or successors by merger, conversion or consolidation. 
 Section 7.13. Preferential Collection of
Claims Against the Company. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Notes), the Trustee shall be subject to the provisions of the TIA regarding the collection of the claims against the
Company (or any such other obligor). 
 Section 7.14. Reports By The Trustee. (a) Within sixty (60) days after
May 15 of each year commencing with the year 2013, the Trustee shall transmit to Holders and other persons such reports dated as of May 15 of the year in which such reports are made concerning the Trustee and its actions under this
Indenture as may be required pursuant to the TIA. 
 (b) A copy of each such report shall, at the time of such transmission to
Noteholders, be furnished to the Company and be filed by the Trustee with each stock exchange upon which the Notes are listed and also with the SEC. The Company agrees to notify the Trustee when and as the Notes become admitted to trading on any
national securities exchange or become delisted therefrom. 
 Section 7.15. Trustee to Give Notice of Default, But May
Withhold in Certain Circumstances. The Trustee shall transmit to the Noteholders, as the names and addresses of such Holders appear on the Note Register, notice by mail of all Defaults which have occurred, such notice to be transmitted within 90
days after the occurrence thereof, unless such defaults shall have been cured before the giving of such notice; provided that, except in the case of Default in the payment of the principal of, or interest on any of, the Notes when due or in the
payment of any repurchase obligation, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee, or a trust committee of directors or trustees and/or Responsible Officers of the
Trustee in good faith determines that the withholding of such notice is in the best interests of the Noteholders.

 ARTICLE 8 
 DISCHARGE OF INDENTURE 
 Section
8.01. Discharge Of Indenture. When all outstanding Notes will become due and payable within one year of their Stated Maturity and the Company has deposited with the Trustee cash sufficient to pay and discharge all outstanding Notes on the
date of their Stated Maturity, then the Company may discharge its obligations under this Indenture while Notes remain outstanding; provided that provisions of Section 2.04, Section 2.05, Section 2.06, Section 2.07,
Section 2.08, Section 4.01, Section 4.05, Section 7.06, Article 10 and this Article 8 shall survive such discharge. The Trustee shall join in the execution of a document prepared by the Company acknowledging satisfaction and
discharge of this Indenture on demand of the Company accompanied by an Officers’ Certificate and Opinion of Counsel as required by Section 11.04 and at the cost and expense of the Company; the Company, however, hereby agrees to reimburse
the Trustee for any costs or expenses thereafter reasonably and properly incurred by the Trustee and to compensate the Trustee for any services thereafter reasonably and properly rendered by the Trustee in connection with this Indenture or the
Notes. The Company will remain obligated to issue shares of its common stock upon conversion of the Notes until such maturity as described under Article 10. 
 Section 8.02. [Intentionally Omitted]. 
 Section 8.03. Paying Agent to
Repay Monies Held. Upon the discharge of this Indenture, all monies then held by any Paying Agent of the Notes (other than the Trustee) shall, upon written request of the Company, be repaid to it or paid to the Trustee, and thereupon such Paying
Agent shall be released from all further liability with respect to such monies. 
 Section 8.04. Return Of Unclaimed Monies.
Subject to the requirements of applicable law, any monies deposited with or paid to the Trustee or the Paying Agent for payment of the principal of, or interest on Notes and not applied but remaining unclaimed by the holders of Notes for two
years after the date upon which the principal of, or interest on, such Notes, as the case may be, shall have become due and payable, shall be repaid to the Company by the Trustee or the Paying Agent on written demand and all liability of the Trustee
or the Paying Agent shall thereupon cease with respect to such monies; and the holder of any of the Notes shall thereafter look only to the Company for any payment that such holder may be entitled to collect unless an applicable abandoned property
law designates another Person.

 ARTICLE 9 
 SUPPLEMENTAL INDENTURES 
 Section 9.01. Without
Consent Of Holders. The Company and the Trustee may, from time to time and at any time, enter into an indenture or indentures supplemental hereto without the consent of any Noteholder for one or more of the following purposes: 

(a) adding to the Company’s covenants for the benefit of the Holders; 

(b) surrendering any right or power conferred upon the Company, including, without limitation, the right to pay the Purchase Price upon
Change of Control in shares of the Company’s Common Stock; 
 (c) providing for the assumption of the Company’s
obligations to the Holders in the case of a merger, consolidation, conveyance, transfer or lease in accordance with Article 5; 

(d) reducing the Conversion Price; provided that the reduction will not adversely affect the interests of Holders in any material
respect; 
 (e) complying with the requirements of the SEC in order to effect or maintain the qualification of this Indenture
under the TIA; 
 (f) curing any ambiguity or correcting or supplementing any defective provision contained in this Indenture;
provided that such modification or amendment does not adversely affect the interests of the Holders in any material respect; 

(g) adding or modifying any other provisions which the Company and the Trustee may deem necessary or desirable and which will not
adversely affect the interests of the Holders in any material respect; 
 (h) complying with the requirements regarding merger
or transfer of assets; or 
 (i) providing for uncertificated Notes in addition to the certificated Notes so long as such
uncertificated Notes are in registered form for purpose of the Internal Revenue Code of 1986. 
 Section 9.02. With Consent
Of Holders. With the written consent of the Holders of at least a majority in aggregate principal amount of the Notes at the time outstanding, the Company and the Trustee may, from time to time and at any time, enter into an indenture or
indentures supplemental hereto for the purpose of adding any provisions to or change in any manner or eliminating any of the provisions of this Indenture or any supplemental indenture or of modifying in any manner the rights of the Holders of the
Notes. However, without the consent of each Noteholder so affected, a supplemental indenture may not: 

  
 47 

 (a) change the maturity of the principal of or any installment of interest on any Note;

 (b) reduce the principal amount of, or interest on, any Note; 

(c) change the currency of payment of such Note or interest thereon; 

(d) impair the right to institute suit for the enforcement of any payment on or with respect to any Note; 

(e) modify the Company’s obligations to maintain an office or agency in New York City; 

(f) except as otherwise permitted or contemplated by provisions concerning corporate reorganizations, adversely affect the repurchase
option of Holders upon a Change of Control or the conversion rights of Holders; or 
 (g) reduce the percentage in aggregate
principal amount of Notes outstanding necessary to modify or amend this Indenture or to waive any past default. 
 It shall not
be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such consent approves the substance thereof. 

After a supplemental indenture under this Section 9.02 becomes effective, the Company shall mail to each Holder a notice briefly
describing the supplemental indenture. 
 Section 9.03. Compliance with Trust Indenture Act. Every supplemental indenture
executed pursuant to this Article shall comply with the TIA; provided that this Section 9.03 shall not require such supplemental indenture or the Trustee to be qualified under the TIA prior to the time such qualification is in fact
required under the terms of the TIA or the Indenture has been qualified under the TIA, nor shall it constitute any admission or acknowledgment by any party to such supplemental indenture that any such qualification is required prior to the time such
qualification is in fact required under the terms of the TIA or the Indenture has been qualified under the TIA. 
 Section
9.04. Revocation and Effect of Consents, Waivers and Actions. Until a supplemental indenture, waiver or other action by Holders becomes effective, a consent thereto by a Holder of a Note hereunder is a continuing consent by the Holder and
every subsequent Holder of that Note or portion of the Note that evidences the same obligation as the consenting Holder’s Note, even if notation of the consent, waiver or action is not made on the Note. However, any such Holder or subsequent
Holder may revoke the consent, waiver or action as to such Holder’s Note or portion of the Note if the Trustee receives the notice of revocation before the date the supplemental indenture, waiver or action becomes effective. After a
supplemental indenture, waiver or action becomes effective, it shall bind every Noteholder. 

  
 48 

 Section 9.05. Notation on or Exchange of Notes. Notes authenticated and delivered
after the execution of any supplemental indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall
so determine, new Notes so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee or an
Authenticating Agent in exchange for outstanding Notes. 
 Section 9.06. Trustee to Sign Supplemental Indentures. The
Trustee shall sign any supplemental indenture authorized pursuant to this Article 9 if the amendment contained therein does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not,
sign such supplemental indenture. In signing such supplemental indenture the Trustee shall be provided with, and (subject to the provisions of Section 7.01) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion
of Counsel stating that such amendment is authorized or permitted by this Indenture. 
 Section 9.07. Effect of Supplemental
Indentures. Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of
Notes theretofore or thereafter authenticated and delivered hereunder shall be bound thereby. 
 ARTICLE 10 

CONVERSION 
 Section 10.01. Conversion Right and Conversion Price. Subject to and upon compliance with the provisions of this Article, at the option of the Holder thereof, any Note or any portion of the
principal amount thereof which is $1,000 or an integral multiple of $1,000 may be converted at the principal amount thereof, or of such portion thereof, into duly authorized, fully paid and nonassessable shares of Common Stock, at the Conversion
Price, determined as hereinafter provided, in effect at the time of conversion. Such conversion right shall expire at the close of business on the final maturity date of the Notes. 

In the case of a Change of Control for which the Holder exercises its repurchase right with respect to a Note or portion thereof, such
conversion right in respect of the Note or portion thereof shall expire at the close of business on the Business Day immediately preceding the Change of Control Purchase Date. 

  
 49 

 The price at which shares of Common Stock shall be delivered upon conversion (the
“Conversion Price”) shall be initially equal to $16.575 per share of Common Stock. The Conversion Price shall be adjusted in certain instances as provided in paragraphs (a), (b), (c), (d), (e), (f), (h) and (i) of
Section 10.04 hereof. 
 Section 10.02. Exercise of Conversion Right. To exercise the conversion right, the Holder
of any Note to be converted shall surrender such Note duly endorsed or assigned to the Company or in blank, at the office of any Conversion Agent, accompanied by a duly signed conversion notice substantially in the form attached to the Note to the
Company stating that the Holder elects to convert such Note or, if less than the entire principal amount thereof is to be converted, the portion thereof to be converted. 
 Notes surrendered for conversion during the period from the close of business on any Regular Record Date to the opening of business on the next succeeding Interest Payment Date shall be accompanied by
payment in New York Clearing House funds or other funds acceptable to the Company of an amount equal to the interest to be received on such Interest Payment Date on the principal amount of Notes being surrendered for conversion. 

Notes shall be deemed to have been converted immediately prior to the close of business on the day of surrender of such Notes for
conversion in accordance with the foregoing provisions, and at such time the rights of the Holders of such Notes as Holders shall cease, and the Person or Persons entitled to receive the Common Stock issuable upon conversion shall be treated for all
purposes as the record holder or holders of such Common Stock at such time. As promptly as practicable on or after the conversion date, the Company shall cause to be issued and delivered to such Conversion Agent a certificate or certificates for the
number of full shares of Common Stock issuable upon conversion, together with payment in lieu of any fraction of a share as provided in Section 10.03 hereof. 
 In the case of any Note which is converted in part only, upon such conversion the Company shall execute and the Trustee or an Authenticating Agent shall authenticate and deliver to the Holder thereof, at
the expense of the Company, a new Note or Notes of authorized denominations in aggregate principal amount equal to the unconverted portion of the principal amount of such Notes. 

Section 10.03. Fractions of Shares. No fractional shares of Common Stock shall be issued upon conversion of any Note or Notes. If
more than one Note shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issued upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Notes (or
specified portions thereof) so surrendered. Instead of any fractional share of Common Stock which would otherwise be issued upon conversion of any Note or Notes (or specified portions thereof), the Company shall pay a cash adjustment in respect of
such fraction (calculated to the nearest one-100th of a share) in an amount equal to the same fraction of the quoted price of the Common Stock as of the Trading Day preceding the date of conversion. 

  
 50 

 Section 10.04. Adjustment of Conversion Price. The Conversion Price shall be subject
to adjustments, calculated by the Company, from time to time as follows: 
 (a) In case the Company shall hereafter pay a
dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Price in effect at the opening of business on the date following the date fixed for the determination of stockholders entitled
to receive such dividend or other distribution shall be reduced by multiplying such Conversion Price by a fraction: 
 (1) the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the Record Date (as defined in Section 10.04(g)) fixed for such determination, and

 (2) the denominator of which shall be the sum of such number of shares and the total number of shares
constituting such dividend or other distribution. 
 Such reduction shall become effective immediately after the opening of business on the day
following the Record Date. For the purpose of this paragraph (a), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company. The Company will not pay any dividend or make any
distribution on shares of Common Stock held in the treasury of the Company. If any dividend or distribution of the type described in this Section 10.04(a) is declared but not so paid or made, the Conversion Price shall again be adjusted to the
Conversion Price which would then be in effect if such dividend or distribution had not been declared. 
 (b) In case the
outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be
proportionately reduced, and conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Conversion Price in effect at the opening of business on the day following the day upon which
such combination becomes effective shall be proportionately increased, such reduction or increase, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or
combination becomes effective. 
 (c) In case the Company shall issue rights or warrants to all holders of its outstanding
shares of Common Stock entitling them (for a period expiring within forty-five (45) days after the date fixed for determination of stockholders entitled to receive such rights or warrants) to subscribe for or purchase shares of Common Stock (or
securities convertible into Common Stock) at a price per share (or having a conversion price per share) less than the Current Market Price (as defined in Section 10.04(g)) on the 

  
 51 

 
Record Date fixed for the determination of stockholders entitled to receive such rights or warrants, the Conversion Price shall be adjusted so that the same shall equal the price determined by
multiplying the Conversion Price in effect immediately prior to such Record Date by a fraction: 
 (1) the
numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the Record Date plus the number of shares which the aggregate offering price of the total number of shares so offered for subscription or
purchase (or the aggregate conversion price of the convertible securities so offered) would purchase at such Current Market Price, and 
 (2) the denominator of which shall be the number of shares of Common Stock outstanding on the close of business on the Record Date plus the total number of additional shares of Common Stock so offered for
subscription or purchase (or into which the convertible securities so offered are convertible). 
 Such adjustment shall become effective
immediately after the opening of business on the day following the Record Date fixed for determination of stockholders entitled to receive such rights or warrants. To the extent that shares of Common Stock (or securities convertible into Common
Stock) are not delivered pursuant to such rights or warrants, upon the expiration or termination of such rights or warrants the Conversion Price shall be readjusted to the Conversion Price which would then be in effect had the adjustments made upon
the issuance of such rights or warrants been made on the basis of the delivery of only the number of shares of Common Stock (or securities convertible into Common Stock) actually delivered. In the event that such rights or warrants are not so
issued, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such Record Date had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase
shares of Common Stock at less than such Current Market Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received for such rights or warrants and any amount
payable on exercise or conversion thereof, the value of such consideration if other than cash, to be determined by the Board of Directors. 
 (d) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of Capital Stock of the Company (other than any dividends or distributions to
which Section 10.04(a) applies) or evidences of its indebtedness, cash or other assets, including securities, but excluding (1) any rights or warrants referred to in Section 10.04(c), (2) any stock, securities or other property
or assets (including cash) distributed in connection with a reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance to which Section 10.11 hereof applies and (3) dividends and
distributions paid exclusively in cash (the securities described in foregoing clauses (1), (2) and (3) hereinafter in this Section 10.04(d) called the “excluded securities”), then, in each such case (unless the
Company elects to reserve such securities for distribution to the Noteholders upon the conversion of 

  
 52 

 
the Notes so that any such Holder converting Notes will receive upon such conversion, in addition to the shares of Common Stock to which such Holder is entitled, the amount and kind of such
securities which such Holder would have received if such Holder had converted its Notes into Common Stock immediately prior to the Record Date), subject to the second succeeding paragraph of this Section 10.04(d), the Conversion Price shall be
adjusted so that the same shall be equal to the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on the Record Date (as defined in Section 10.04(g)) with respect to such distribution by a
fraction: 
 (1) the numerator of which shall be the Current Market Price (determined as provided in
Section 10.04(g)) on such Record Date less the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution) on such Record Date of the portion of the securities so
distributed (other than excluded securities) applicable to one share of Common Stock (determined on the basis of the number of shares of the Common Stock outstanding on the Record Date), and 

(2) the denominator of which shall be such Current Market Price. 
 Such reduction shall become effective immediately prior to the opening of business on the day following the Record Date. However, in the event that the then fair market value (as so determined) of the
portion of the securities so distributed (other than excluded securities) applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall
be made so that each Holder shall have the right to receive upon conversion of a Note (or any portion thereof) the amount of securities so distributed (other than excluded securities) such Holder would have received had such Holder converted such
Note (or portion thereof) immediately prior to such Record Date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such
dividend or distribution had not been declared. 
 If the Board of Directors determines the fair market value of any
distribution for purposes of this Section 10.04(d) by reference to the actual or when issued trading market for any securities comprising all or part of such distribution (other than excluded securities), it must in doing so consider the prices
in such market over the same period (the “Reference Period”) used in computing the Current Market Price pursuant to Section 10.04(g) to the extent possible, unless the Board of Directors in a Board Resolution determines in good
faith that determining the fair market value during the Reference Period would not be in the best interest of the Holder. 

Rights or warrants distributed by the Company to all holders of Common Stock entitling the holders thereof to subscribe for or purchase
shares of the Company’s Capital Stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”): 

  
 53 

	 	(i)	are deemed to be transferred with such shares of Common Stock; 

  

	 	(ii)	are not exercisable; and 

  

	 	(iii)	are also issued in respect of future issuances of Common Stock, 

 shall be deemed not to have been distributed for purposes of this Section 10.04(d) (and no adjustment to the Conversion Price under this Section 10.04(d) will be required) until the occurrence
of the earliest Trigger Event. If such right or warrant is subject to subsequent events, upon the occurrence of which such right or warrant shall become exercisable to purchase different securities, evidences of indebtedness or other assets or
entitle the holder to purchase a different number or amount of the foregoing or to purchase any of the foregoing at a different purchase price, then the occurrence of each such event shall be deemed to be the date of issuance and Record Date with
respect to a new right or warrant (and a termination or expiration of the existing right or warrant without exercise by the holder thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger
Event or other event (of the type described in the preceding sentence) with respect thereto, that resulted in an adjustment to the Conversion Price under this Section 10.04(d): 

(1) in the case of any such rights or warrants which shall all have been redeemed or repurchased without exercise by any
holders thereof, the Conversion Price shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or
repurchase price received by a holder of Common Stock with respect to such rights or warrant (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and

 (2) in the case of such rights or warrants all of which shall have expired or been terminated without
exercise, the Conversion Price shall be readjusted as if such rights and warrants had never been issued. 
 No adjustment of the Conversion
Price shall be made pursuant to this Section 10.04(d) in respect of rights or warrants distributed or deemed distributed on any Trigger Event to the extent that such rights or warrants are actually distributed, or reserved by the Company for
distribution to holders of Notes upon conversion by such holders of Notes to Common Stock. 
 For purposes of this
Section 10.04(d) and Sections 10.04(a), 10.04(b) and 10.04(c), any dividend or distribution to which this Section 10.04(d) is applicable that also includes shares of Common Stock, a subdivision or combination of Common Stock to which
Section 10.04(b) applies, or rights or warrants to subscribe for or purchase shares of Common Stock to which Section 10.04(c) applies (or any combination thereof), shall be deemed instead to be: 

  
 54 

 (1) a dividend or distribution of the evidences of indebtedness, assets,
shares of Capital Stock, rights or warrants other than such shares of Common Stock, such subdivision or combination or such rights or warrants to which Sections 10.04(a), 10.04(b) and 10.04(c) apply, respectively (and any Conversion Price reduction
required by this Section 10.04(d) with respect to such dividend or distribution shall then be made), immediately followed by 
 (2) a dividend or distribution of such shares of Common Stock, such subdivision or combination or such rights or warrants (and any further Conversion Price reduction required by Sections 10.04(a),
10.04(b) and 10.04(c) with respect to such dividend or distribution shall then be made), except: 
 (A) the
Record Date of such dividend or distribution shall be substituted as (x) “the date fixed for the determination of stockholders entitled to receive such dividend or other distribution”, “Record Date fixed for such
determinations” and “Record Date” within the meaning of Section 10.04(a), (y) “the day upon which such subdivision becomes effective” and “the day upon which such combination becomes
effective” within the meaning of Section 10.04(b), and (z) as “the date fixed for the determination of stockholders entitled to receive such rights or warrants”, “the Record Date fixed for the
determination of the stockholders entitled to receive such rights or warrants” and such “Record Date” within the meaning of Section 10.04(c), and 

(B) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding at the
close of business on the date fixed for such determination” within the meaning of Section 10.04(a) and any reduction or increase in the number of shares of Common Stock resulting from such subdivision or combination shall be
disregarded in connection with such dividend or distribution. 
 (e) In case the Company shall, by dividend or otherwise,
distribute to all holders of its Common Stock cash (excluding any cash that is distributed upon a reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance to which Section 10.11 hereof applies
or as part of a distribution referred to in Section 10.04(d) hereof), then and in each such case, immediately after the close of business on such date, the Conversion Price shall be reduced so that the same shall equal the price determined by
multiplying the Conversion Price in effect immediately prior to the close of business on such Record Date by a fraction: 
 (i) the numerator of which shall be equal to the Current Market Price on the Record Date less an amount equal to the quotient of (x) such amount distributed to all holders of its Common Stock and
(y) the number of shares of Common Stock outstanding on the Record Date, and 

  
 55 

 (ii) the denominator of which shall be equal to the Current Market Price on
such date. 
 However, in the event that the then fair market value (as so determined) of the portion of the securities so distributed (other
than excluded securities) applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right
to receive upon conversion of a Note (or any portion thereof) the amount of cash such Holder would have received had such Holder converted such Note (or portion thereof) immediately prior to such Record Date. In the event that such dividend or
distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared. 

(f) In case a tender offer made by the Company or any of its Subsidiaries for all or any portion of the Common Stock shall expire and
such tender offer (as amended upon the expiration thereof) shall require the payment to stockholders (based on the acceptance (up to any maximum specified in the terms of the tender offer) of Purchased Shares (as defined below)) of an aggregate
consideration having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution) that combined together with: 

(1) the aggregate of the cash plus the fair market value (as determined by the Board of Directors, whose determination
shall be conclusive and set forth in a Board Resolution), as of the expiration of such tender offer, of other consideration payable in respect of any other tender offers, by the Company or any of its Subsidiaries for all or any portion of the Common
Stock expiring within the 12 months preceding the expiration of such tender offer and in respect of which no adjustment pursuant to this Section 10.04(f) has been made, and 

(2) the aggregate amount of any distributions to all holders of the Company’s Common Stock made exclusively in cash
within 12 months preceding the expiration of such tender offer and in respect of which no adjustment pursuant to Section 10.04(e) has been made, exceeds 5% of the product of the Current Market Price (determined as provided in
Section 10.04(g)) as of the last time (the “Expiration Time”) tenders could have been made pursuant to such tender offer (as it may be amended) times the number of shares of Common Stock outstanding (including any tendered
shares) on the Expiration Time, then, and in each such case, immediately prior to the opening of business on the day after the date of the Expiration Time, the Conversion Price shall be adjusted so that the same shall equal the price determined by
multiplying the Conversion Price in effect immediately prior to close of business on the date of the Expiration Time by a fraction: 

  
 56 

 (i) the numerator of which shall be the number of shares of Common Stock
outstanding (including any tendered shares) at the Expiration Time multiplied by the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time, and 

(ii) the denominator of which shall be the sum of (x) the fair market value (determined as aforesaid) of the
aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender offer) of all shares validly tendered and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to
any such maximum, being referred to as the “Purchased Shares”) and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares) on the Expiration Time and the Current Market Price of the
Common Stock on the Trading Day next succeeding the Expiration Time. 
 Such reduction (if any) shall become effective immediately prior to the
opening of business on the day following the Expiration Time. In the event that the Company or any such Subsidiary, as the case may be, is obligated to purchase shares pursuant to any such tender offer, but the Company or any such Subsidiary, as the
case may be, is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such tender offer
had not been made. If the application of this Section 10.04(f) to any tender offer would result in an increase in the Conversion Price, no adjustment shall be made for such tender offer under this Section 10.04(f). 

(g) For purposes of this Section 10.04, the following terms shall have the meanings indicated: 

(1) “Current Market Price” shall mean the average of the daily Closing Prices per share of Common Stock
for the ten consecutive Trading Days immediately prior to the date in question; provided, however, that if: 

(i) the “ex” date (as hereinafter defined) for any event (other than the issuance or distribution
requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 10.04(a), (b), (c), (d), (e) or (f) occurs during such ten consecutive Trading Days, the Closing Price for each Trading Day prior to
(ii) the “ex” date for such other event shall be adjusted by multiplying such Closing Price by the same fraction by which the Conversion Price is so required to be adjusted as a result of such other event; 

(ii) the “ex” date for any event (other than the issuance or distribution requiring such computation)
that requires an adjustment to the Conversion Price pursuant to Section 10.04(a), (b), (c), (d), (e) or (f) occurs on or after the “ex” date for the issuance or distribution requiring such computation and prior to the
day in question, the Closing Price for each Trading Day on and after the “ex” date for 

  
 57 

 
such other event shall be adjusted by multiplying such Closing Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such other event;
and 
 (iii) the “ex” date for the issuance or distribution requiring such computation is prior
to the day in question, after taking into account any adjustment required pursuant to clause (i) or (ii) of this proviso, the Closing Price for each Trading Day on or after such “ex” date shall be adjusted by adding
thereto the amount of any cash and the fair market value (as determined by the Board of Directors in a manner consistent with any determination of such value for purposes of Section 10.04(d) or (f), whose determination shall be conclusive and
set forth in a Board Resolution) of the evidences of indebtedness, shares of Capital Stock or assets being distributed applicable to one share of Common Stock as of the close of business on the day before such “ex” date. 

For purposes of any computation under Section 10.04(f), the Current Market Price of the Common Stock on any date shall be deemed to
be the average of the daily Closing Prices per share of Common Stock for such day and the next two succeeding Trading Days; provided, however, that if the “ex” date for any event (other than the tender offer requiring such
computation) that requires an adjustment to the Conversion Price pursuant to Section 10.04(a), (b), (c), (d), (e) or (f) occurs on or after the Expiration Time for the tender offer requiring such computation and prior to the day in
question, the Closing Price for each Trading Day on and after the “ex” date for such other event shall be adjusted by multiplying such Closing Price by the reciprocal of the fraction by which the Conversion Price is so required to
be adjusted as a result of such other event. For purposes of this paragraph, the term “ex” date, when used: 
 (A) with respect to any issuance or distribution, means the first date on which the Common Stock trades regular way on the relevant exchange or in the relevant market from which the Closing Price was
obtained without the right to receive such issuance or distribution; 
 (B) with respect to any subdivision or
combination of shares of Common Stock, means the first date on which the Common Stock trades regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective, and 

(C) with respect to any tender offer, means the first date on which the Common Stock trades regular way on such exchange
or in such market after the Expiration Time of such offer. 
 Notwithstanding the foregoing, whenever successive adjustments to the Conversion
Price are called for pursuant to this Section 10.04, such adjustments shall be made to the Current Market Price as may be necessary or appropriate to effectuate the intent of this 

  
 58 

 
Section 10.04 and to avoid unjust or inequitable results as determined in good faith by the Board of Directors. 

(2) “fair market value” shall mean the amount which a willing buyer would pay a willing seller in an
arm’s length transaction. 
 (3) “Record Date” shall mean, with respect to any dividend,
distribution or other transaction or event in which the holders of Common Stock have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or converted into any
combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or
otherwise). 
 (h) The Company may make such reductions in the Conversion Price, in addition to those required by
Section 10.04(a), (b), (c), (d), (e) or (f), as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution
of stock (or rights to acquire stock) or from any event treated as such for income tax purposes. 
 To the extent permitted by
applicable law, the Company from time to time may reduce the Conversion Price by any amount for any period of time if the period is at least 20 days and the reduction is irrevocable during the period and the Board of Directors determines in good
faith that such reduction would be in the best interests of the Company, which determination shall be conclusive and set forth in a Board Resolution. Whenever the Conversion Price is reduced pursuant to the preceding sentence, the Company shall mail
to the Trustee and each Holder at the address of such Holder as it appears in the Note Register a notice of the reduction at least 15 days prior to the date the reduced Conversion Price takes effect, and such notice shall state the reduced
Conversion Price and the period during which it will be in effect. 
 (i) No adjustment in the Conversion Price shall be
required unless such adjustment would require an increase or decrease of at least 1% in such price; provided, however, that any adjustments which by reason of this Section 10.04(i) are not required to be made shall be carried forward and
taken into account in any subsequent adjustment. All calculations under this Article 10 shall be made by the Company and shall be made to the nearest one hundredth of a cent or to the nearest one hundredth of a share, as the case may be. No
adjustment need be made for a change in the par value or no par value of the Common Stock. 
 (j) In any case in which this
Section 10.04 provides that an adjustment shall become effective immediately after a Record Date for an event, the Company may defer until the occurrence of such event (i) issuing to the Holder of any Note converted after

  
 59 

 
such Record Date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the adjustment required by such event over and above the
Common Stock issuable upon such conversion before giving effect to such adjustment and (ii) paying to such holder any amount in cash in lieu of any fraction pursuant to Section 10.03 hereof. 

(k) For purposes of this Section 10.04, the number of shares of Common Stock at any time outstanding shall not include shares held
in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not pay any dividend or make any distribution on shares of Common Stock held in
the treasury of the Company. 
 Section 10.05. Notice of Adjustments of Conversion Price. Whenever the Conversion Price
is adjusted as herein provided (other than in the case of an adjustment pursuant to the second paragraph of Section 10.04(h) for which the notice required by such paragraph has been provided), the Company shall promptly file with the Trustee
and any Conversion Agent other than the Trustee an Officers’ Certificate setting forth the adjusted Conversion Price and showing in reasonable detail the facts upon which such adjustment is based. Promptly after delivery of such Officers’
Certificate, the Company shall prepare a notice stating that the Conversion Price has been adjusted and setting forth the adjusted Conversion Price and the date on which each adjustment becomes effective, and shall mail such notice to each Holder at
the address of such Holder as it appears in the Note Register within 20 days of the effective date of such adjustment. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 

Section 10.06. Notice Prior to Certain Actions. In case at any time after the date hereof: 

(1) the Company shall declare a dividend (or any other distribution) on its Common Stock payable otherwise than in cash
out of its capital surplus or its consolidated retained earnings; 
 (2) the Company shall authorize the granting
to the holders of its Common Stock of rights or warrants to subscribe for or purchase any shares of Capital Stock of any class (or of securities convertible into shares of Capital Stock of any class) or of any other rights; 

(3) there shall occur any reclassification of the Common Stock of the Company (other than a subdivision or combination of
its outstanding Common Stock, a change in par value, a change from par value to no par value or a change from no par value to par value), or any merger, consolidation, statutory share exchange or combination to which the Company is a party and for
which approval of any shareholders of the Company is required, or the sale, transfer or conveyance of all or substantially all of the assets of the Company; or 

  
 60 

 (4) there shall occur the voluntary or involuntary dissolution, liquidation
or winding up of the Company; 
 the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of Notes
pursuant to Section 4.03 hereof, and shall cause to be provided to the Trustee and all Holders in accordance with Section 11.02 hereof, at least 20 days (or 10 days in any case specified in clause (1) or (2) above) prior to the
applicable record or effective date hereinafter specified, a notice stating: 
 (A) the date on which a record is
to be taken for the purpose of such dividend, distribution, rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution, rights or warrants are to
be determined, or 
 (B) the date on which such reclassification, merger, consolidation, statutory share
exchange, combination, sale, transfer, conveyance, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of
Common Stock for securities, cash or other property deliverable upon such reclassification, merger, consolidation, statutory share exchange, sale, transfer, dissolution, liquidation or winding up. 

Neither the failure to give such notice nor any defect therein shall affect the legality or validity of the proceedings or actions
described in clauses (1) through (4) of this Section 10.06. 
 Section 10.07. Company to Reserve Common Stock.
The Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, for the purpose of effecting the conversion of Notes, the full number of shares of fully paid and
nonassessable Common Stock then issuable upon the conversion of all Notes outstanding. 
 Section 10.08. Taxes on
Conversions. Except as provided in the next sentence, the Company will pay any and all taxes (other than taxes on income) and duties that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Notes
pursuant hereto. A Holder delivering a Note for conversion shall be liable for and will be required to pay any tax or duty which may be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock in a name other
than that of the Holder of the Note or Notes to be converted, and no such issue or delivery shall be made unless the Person requesting such issue has paid to the Company the amount of any such tax or duty, or has established to the satisfaction of
the Company that such tax or duty has been paid. 

  
 61 

 Section 10.09. Covenant as to Common Stock. The Company covenants that all shares of
Common Stock which may be issued upon conversion of Notes will upon issue be fully paid and nonassessable and, except as provided in Section 10.08, the Company will pay all taxes, Liens and charges with respect to the issue thereof. 

Section 10.10. Cancellation of Converted Notes. All Notes delivered for conversion shall be delivered to the Trustee to be
canceled by or at the direction of the Trustee, which shall dispose of the same as provided in Section 2.11. 
 Section
10.11. Effect of Reclassification, Consolidation, Merger or Sale. If any of following events occur, namely: 
 (1) any reclassification or change of the outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a
subdivision or combination), 
 (2) any merger, consolidation, statutory share exchange or combination of the
Company with another corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock or 

(3) any sale or conveyance of all or substantially all the properties and assets of the Company to any other corporation
as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, 
 the Company or the successor or purchasing corporation, as the case may be, shall execute with the Trustee and the Company a supplemental indenture (which shall comply with the TIA as in force at the date
of execution of such supplemental indenture if such supplemental indenture is then required to so comply) providing that such Note shall be convertible into the kind and amount of shares of stock and other securities or property or assets (including
cash) which such Holder would have been entitled to receive upon such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance had such Notes been converted into Common Stock immediately prior to
such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance assuming such holder of Common Stock did not exercise its rights of election, if any, as to the kind or amount of securities, cash or
other property receivable upon such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance (provided that, if the kind or amount of securities, cash or other property receivable upon such
reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised
(“Non-Electing Share”), then for the purposes of this Section 10.11 the 

  
 62 

 
kind and amount of securities, cash or other property receivable upon such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance for each
Non-Electing Share shall be deemed to be the kind and amount so receivable per share by a plurality of the Non-Electing Shares). Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to
the adjustments provided for in this Article 10. If, in the case of any such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, the stock or other securities and assets receivable thereupon by
a holder of shares of Common Stock includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change, merger, consolidation, statutory
share exchange, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of
Directors shall reasonably consider necessary by reason of the foregoing, including to the extent practicable the provisions providing for the repurchase rights set forth in Section 3.05 hereof. 

The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at the address of such Holder
as it appears on the Note Register, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. 

The above provisions of this Section 10.11 shall similarly apply to successive reclassifications, mergers, consolidations, statutory
share exchanges, combinations, sales and conveyances. 
 If this Section 10.11 applies to any event or occurrence,
Section 10.04 hereof shall not apply. 
 Section 10.12. Responsibility of Trustee for Conversion Provisions. The
Trustee, subject to the provisions of Section 7.01 hereof, and any Conversion Agent shall not at any time be under any duty or responsibility to any Holder of Notes to determine whether any facts exist which may require any adjustment of the
Conversion Price, or with respect to the nature or intent of any such adjustments when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. Neither the Trustee, subject
to the provisions of Section 7.01 hereof, nor any Conversion Agent shall be accountable with respect to the validity or value (of the kind or amount) of any Common Stock, or of any other securities or property, which may at any time be issued
or delivered upon the conversion of any Note; and it or they do not make any representation with respect thereto. Neither the Trustee, subject to the provisions of Section 7.01 hereof, nor any Conversion Agent shall be responsible for any
failure of the Company to make any cash payment or to issue, transfer or deliver any shares of stock or share certificates or other securities or property upon the surrender of any Note for the purpose of conversion; and the Trustee, subject to the
provisions of Section 7.01 hereof, and any Conversion Agent shall not be responsible or liable for any failure of the Company to comply with any of the covenants of the Company contained in this Article.

shall be taken on the next succeeding day that is not a Legal Holiday, and, if the action to be taken on such date is a payment in respect of the Notes, no interest, if any, shall accrue for the intervening period. 

Section 11.09. Governing Law. THIS INDENTURE AND THE NOTES WILL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE

stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the Notes or this Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Note,
each Noteholder shall waive and release all such liability. The waiver and release shall be part of the consideration for the issue of the Notes. 
 Section 11.11. Successors. All agreements of the Company in this Indenture and the Notes shall bind its successor. All agreements of the Trustee in this Indenture shall bind its successor.

Person, other than the parties hereto, any Paying Agent, any authenticating agent, any Note Registrar and their successors hereunder and the holders of Notes, any benefit or any legal or equitable right, remedy or claim under this Indenture.

 Section 11.13. Table of Contents, Heading, Etc. The table of contents and the titles and headings of the Articles and
Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part hereof, and shall in no way modify or restrict any of the terms or provisions hereof.

that shall be authorized to act on its behalf, and subject to its direction, in the authentication and delivery of Notes in connection with the original issuance thereof and transfers and exchanges of Notes hereunder, including under Sections 2.03,
2.07, 2.08, 3.08 and 10.02, as fully to all intents and purposes as though the authenticating agent had been expressly authorized by this Indenture and those Sections to authenticate and deliver Notes. For all purposes of this Indenture, the
authentication and delivery of Notes by the Authenticating Agent shall be deemed to be authentication and delivery of such Notes “by the Trustee” and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent shall be deemed to satisfy any requirement hereunder or in the Notes for the Trustee’s certificate of authentication. Such Authenticating Agent shall at all times be a Person eligible to serve as trustee hereunder pursuant
to Section 7.09. 
 Any corporation into which any Authenticating Agent may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, consolidation or conversion to which any Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of any Authenticating
Agent, shall be the successor of the Authenticating Agent hereunder, if such successor corporation is otherwise eligible under this Section 11.14, without the execution or filing of any paper or any further act on the part of the parties hereto
or the Authenticating Agent or such successor corporation. 

  
 67 

 Any Authenticating Agent may at any time resign by giving written notice of resignation to
the Trustee and to the Company. The Trustee may at any time terminate the agency of any Authenticating Agent by giving written notice of termination to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon
such a termination, or in case at any time any Authenticating Agent shall cease to be eligible under this Section, the Trustee shall either promptly appoint a successor Authenticating Agent or itself assume the duties and obligations of the former
Authenticating Agent under this Indenture and, upon such appointment of a successor Authenticating Agent, if made, shall give written notice of such appointment of a successor Authenticating Agent to the Company and shall mail notice of such
appointment of a successor Authenticating Agent to all holders of Notes as the names and addresses of such holders appear on the Note Register. 
 The Company agrees to pay to the Authenticating Agent from time to time such reasonable compensation for its services as shall be agreed upon in writing between the Company and the Authenticating Agent.

 The provisions of Sections 2.12, 7.03, 7.04, 7.07 and this Section 11.14 shall be applicable to any Authenticating
Agent. 
 Section 11.15. Execution In Counterparts. This Indenture may be executed in any number of counterparts, each of
which shall be an original, but such counterparts shall together constitute but one and the same instrument. 

Section 11.16. Waiver of Jury Trial. EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTION CONTEMPLATED HEREBY. 

Section 11.17. Force Majeure. In no event shall the Trustee be responsible or liable for any failure or delay in the
performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances,
nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent
with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

 [FORM OF REVERSE SIDE OF NOTE] 

5 
1/4% Convertible Senior Note due 2013 

1. Cash Interest. 
 The Company promises to pay interest in cash on the principal amount of this Note at the rate per annum of
5 1/4%. The Company will pay cash interest on October 6, 2012 to Holders of record on the Issue Date and thereafter semi-annually in arrears on April 6 and October 6 of each year (each an
“Interest Payment Date”), beginning on April 6, 2013, to Holders of record at the close of business on March 15 and September 15 (whether or not a business day) (each a “Regular Record Date”), as the
case may be, immediately preceding such Interest Payment Date. The Company will pay interest in arrears on the Maturity Date to the Holder to whom it pays the principal of this Note. Cash interest on the Notes will accrue from the most recent date
to which interest has been paid or duly provided or, if no interest has been paid, from the Issue Date. Cash interest will be computed on the basis of a 360-day year of twelve 30-day months. The Company shall pay cash interest on overdue principal
at the rate borne by the Notes plus 2% per annum, and it shall pay interest in cash on overdue installments of cash interest at the same rate to the extent lawful. All such overdue cash interest shall be payable on demand. 

2. Method of Payment. 
 Subject
to the terms and conditions of the Indenture, the Company will make payments in respect of the principal of, and cash interest on, this Note and in respect of Change of Control Purchase Price to Holders who surrender Notes to a Paying Agent to
collect such payments in respect of the Notes. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. However, the Company may make such cash payments by
check payable in such money. A holder of Notes with an aggregate principal amount in excess of $5,000,000 will be paid by wire transfer in immediately available funds at the election of such holder. Any payment required to be made on any day that is
not a Business Day will be made on the next succeeding Business Day. 
 3. Paying Agent, Conversion Agent and Note Registrar. 

Initially, The Bank of New York Mellon Trust Company, N.A. (the “Trustee”), will act as Paying Agent, Conversion Agent
and Note Registrar. The Company may appoint and change any Paying Agent, Conversion Agent, Note Registrar or co-registrar without notice, other than notice to the Trustee except that the Company will maintain at least one Paying Agent in the State
of New York, City of New York, Borough of Manhattan, which shall initially be an office or agency of the Trustee. The Company or any of its Subsidiaries or any of their Affiliates may act as Paying Agent, Conversion Agent, Note Registrar or
co-registrar.

 4. Indenture. 
 The Company issued the Notes under an Indenture dated as of September 13, 2012 (the “Indenture”), between the Company and the Trustee. The terms of the Notes include those stated in
the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as in effect from time to time (the “TIA”). Capitalized terms used herein and not defined herein have the meanings ascribed thereto
in the Indenture. The Notes are subject to all such terms, and Noteholders are referred to the Indenture and the TIA for a statement of those terms. 
 The Notes are general unsecured obligations of the Company limited to $67,832,000 aggregate principal amount (subject to Section 2.08 of the Indenture). The Indenture does not limit other
indebtedness of the Company, secured or unsecured. 
 5. Redemption and Repurchase by the Company at the Option of the Holder. 

Prior to Stated Maturity, the Company, at its option, may redeem the Notes, in whole or in part, in accordance with the Indenture on the
Redemption Date for a Redemption Price in cash equal to 100% of the principal amount of the Notes plus any accrued and unpaid interest on the Notes redeemed to but not including the Redemption Date if the Closing Price of the Company’s Common
Stock has exceeded 130% of the Conversion Price for at least 20 Trading Days in any consecutive 30 Trading Day period. In addition, if on any Interest Payment Date, the aggregate principal amount of the Notes outstanding is less than 15% of the
aggregate principal amount of Notes outstanding after the Issue Date, the Company, at its option, may redeem the Notes, in whole but not in part, in accordance with the Indenture on the Redemption Date for a Redemption Price in cash equal to 100% of
the principal amount of the Notes plus any accrued and unpaid Interest on the Notes to but not including the Redemption Date. The Company will make an additional payment equal to the total value of the aggregate amount of the interest otherwise
payable on the Notes from the last day through which Interest was paid on the Notes through the Redemption Date. 
 If there
shall have occurred a Change of Control (subject to certain conditions provided for in the Indenture), each Holder, at such Holder’s option, shall have the right, in accordance with the provisions of the Indenture, to require the Company to
purchase its Notes (or any portion of the principal amount hereof that is at least $1,000 or any whole multiple thereof, provided that the portion of the principal amount of this Note to be outstanding after such purchase is at least equal to
$1,000) at the Change of Control Purchase Price in cash or Common Stock, at the Company’s option, plus any accrued and unpaid interest to but not including the Change of Control Purchase Date. 

A written notice of the Change of Control will be given to the Holders as provided in the Indenture. To exercise a purchase right, a
Holder must deliver to the Trustee a Change of Control Purchase Notice as provided in the Indenture. 
 Holders have the right
to withdraw any Change of Control Purchase Notice by delivering to the Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture.

 6. Conversion. 
 Subject to the next two succeeding sentences, a Holder of a Note may convert it into Common Stock of the Company at any time before the close of business on the final maturity date of the Note. A Note in
respect of which a Holder has delivered a Change of Control Purchase Notice exercising the option of such Holder to require the Company to purchase such Note may be converted only if such notice of exercise is withdrawn in accordance with the terms
of the Indenture. 
 The initial Conversion Price shall be initially equal to $16.575 per share of Common Stock, subject to
adjustment in certain events described in the Indenture. The Company shall pay a cash adjustment as provided in the Indenture in lieu of any fractional share of Common Stock. 
 To convert a Note, a Holder must (1) complete and manually sign the conversion notice below (or complete and manually sign a facsimile of such notice) and deliver such notice to the Conversion Agent,
(2) surrender the Note to the Conversion Agent, (3) furnish appropriate endorsements and transfer documents if required by the Conversion Agent, the Company or the Trustee and (4) pay any transfer or similar tax, if required.

 7. Denominations; Transfer; Exchange. 
 The Notes are in fully registered form, without coupons, in denominations of $1,000 of principal amount and integral multiples of $1,000. A Holder may transfer or exchange Notes in accordance with the
Indenture. The Note Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Note Registrar need not transfer or
exchange any Notes in respect of which a Change of Control Purchase Notice has been given and not withdrawn (except, in the case of a Note to be purchased in part, the portion of the Note not to be purchased). 

8. Persons Deemed Owners. 
 The
registered Holder of this Note may be treated as the owner of this Note for all purposes.

the consent of any Noteholder, the Company and the Trustee may amend the Indenture or the Notes, among other things, to cure any ambiguity, omission, defect or inconsistency, or to comply with Article 5 of the Indenture, or to make any change that
does not adversely affect the rights of any Noteholder, or to comply with any requirement of the SEC in connection with the qualification of the Indenture under the TIA. 
 11. Defaults and Remedies. 
 Under the Indenture, Events of Default include
(1) the Company fails to pay when due the principal of any of the Notes at maturity, upon exercise of a repurchase right or otherwise; (2) the Company fails to pay an installment of interest on any of the Notes that continues for 30 days

(7) certain events of bankruptcy, insolvency or reorganization with respect to the Company or any Significant Subsidiary or any Subsidiaries of the Company which in the aggregate would constitute a Significant Subsidiary. If an Event of Default
(other than an Event of Default specified in clause (7) above) occurs and is continuing, the Trustee, or the Holders of at least 25% in aggregate principal amount of the Notes at the time outstanding, may declare all the Notes to be due and
payable immediately. Certain events of bankruptcy or insolvency are Events of Default which will result in the Notes becoming due and payable immediately upon the occurrence of such Events of Default. 

  
 A-7

 Noteholders 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 reasonable indemnity or security. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Notes at the time outstanding may direct the
Trustee in its exercise of any trust or power. The Trustee may withhold from Noteholders notice of any continuing Default (except a Default in payment of amounts specified in clause (1) or (2) above) if it determines that withholding
notice is in their interests. 
 12. Trustee Dealings with the Company. 

Subject to certain limitations imposed by the TIA, the Trustee under the Indenture, 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 Trustee.

 13. No Recourse Against Others. 
 A director, officer, employee or stockholder, as such, of the Company shall 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 Noteholder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Notes.

 WHEREAS, the
Company desires assurance of the continued association and services of the Employee in order to continue to retain the Employee’s experience, skills, abilities, background and knowledge, and is willing to continue to engage the Employee’s

 WHEREAS, Employee desires to be in the continued
employ of the Company, and is willing to accept such continued employment on the terms and conditions set forth in this Agreement. 
 NOW,
THEREFORE, the parties hereto agree to the terms and conditions of this Agreement as follows: 
 1. Employment for Term. The Company
hereby agrees to employ Employee and Employee hereby accepts such employment with the Company for the period of 36 months beginning on the Effective Date. The term of this Agreement (the “Term”) shall continue until the termination of
Employee’s employment in accordance with the provisions of this Agreement. The termination of Employee’s employment under this Agreement shall end the Term but shall not terminate Employee’s or the Company’s other obligations
that are intended to survive the termination of this Agreement (including without limitation, the payments under Section 7 and Employee’s obligations under Section 8). 
 2. Position and Duties. During the Term, Employee shall serve as Chief Executive Officer and a Director of the Company, perform such duties as are consistent with his position and report to the
Board of Directors of the Company. During the Term, Employee shall also hold such additional positions and titles as the Board of Directors of the Company (the “Board”) may determine from time to time. During the Term, Employee shall
devote as much time as is necessary to satisfactorily perform his duties as the Chief Executive Officer of the Company. Without limitation of the foregoing, the Company hereby acknowledges that it consents to Employee’s participation in those
outside activities described on Exhibit A hereto. Employee may engage in any civic and not-for-profit activities so long as such activities do not materially interfere with the performance of his duties hereunder or present a conflict of interest
with the Company. During the Term of this Agreement, Employee agrees not to acquire, assume or participate in, directly or indirectly, any position, investment or interest known by the Employee to be adverse or antagonistic to the Company, its
business or prospects, its financial position, or otherwise or in any company, person or entity that is, directly or indirectly, in competition with the business of the Company or any of its affiliates. 

The Company shall nominate Employee, and use its best efforts to have Employee elected to the Board of Directors of the Company (the “Board”)
and be appointed as Chairman of the Board throughout the Term of this Agreement and, subject to the fiduciary duties of the Board to act in the best interests of the stockholders, shall include him in the management slate for election as a director

 (b) Annual Review. The Base Salary shall be reviewed at the end of each calendar
year (the first such review to occur at the end of calendar year 2012). 
 (d) Other and Additional Compensation.
Subsection (a) above establishes Employee’s compensation during the Term which shall not preclude the Board from awarding Employee a higher salary or any bonuses or stock options, restricted stock or other forms of additional equity awards
in the discretion of the Board during the Term at any time. The Employee shall be eligible for an annual discretionary bonus (hereinafter referred to as the “Bonus”) with a target amount of fifty percent (50%) of the Base Salary,
subject to standard deductions and withholdings, based on the Compensation Committee’s determination, in good faith, and based upon the Employee’s individual achievement and company performance objectives as set by the Board or the
Compensation Committee, of whether the Employee has met such performance milestones as are established for the Employee by the Board or the Compensation Committee, in good faith, in consultation with the Employee (hereinafter referred to as the
“Performance Milestones”). The Performance Milestones will be based on certain factors including, but not limited to, the Employee’s performance and the Company’s financial performance. The Employee’s Bonus target will be
reviewed annually and may be adjusted by the Board or the Compensation Committee in its discretion, provided however, that the Bonus target may only be reduced upon Employee’s written consent. The Employee must be employed on the date the Bonus
is awarded to be eligible for the Bonus, subject to the termination provisions hereof. Bonuses shall be paid during the calendar quarter following the calendar quarter for which such Bonus was earned when Performance Milestones are met during a
calendar quarter. Fourth quarter Bonuses and Bonuses calculated on the basis of partial Performance Milestone satisfaction shall be paid within 120 days of fiscal year-end.

Agreement, Employee shall be entitled to paid vacation at the rate of (4) weeks per annum. In accordance with Company policy, unused vacation may not be carried over from year to year. 
 5. Expenses. The Company shall reimburse Employee for actual, reasonable out-of-pocket expenses incurred by him in the performance of his services for the Company upon the receipt of appropriate
documentation of such expenses which shall be submitted in such form, and with such supporting documentation, as called for or required by Company policy. 
 6. Termination. 
 (a) General. The Term shall end immediately upon
Employee’s death. Subject to the notice provisions described below in Section 6(b), Employee’s employment shall be terminable at will at any time, with or without good cause or for any or no cause, at the Employee’s option or at
the option of the Company. In the event of termination, there will be no further obligations or liabilities of either the Employee or the Company. 
 (b) Notice of Termination. Either party shall give a 90 day written notice of termination to the other party for termination to be triggered. 

(c) Notification of New Employer. In the event that Employee leaves the employ of the Company, Employee grants consent to

of this Agreement shall be validated and shall be enforced to the fullest extent permitted by law. If for any reason any provision of this Agreement containing restrictions is held to cover an area or to be for a length of time that is unreasonable
or in any other way is construed to be too broad or to any extent invalid, such provision shall not be determined to be entirely null, void and of no effect; instead, it is the intention and desire of both the Company and Employee that, to the
extent that the provision is or would be valid or enforceable under applicable law, any court of competent jurisdiction or arbitrator acting pursuant to Section 18 below shall construe and interpret or reform this Agreement to provide for a
restriction having the maximum enforceable area, time period and such other constraints or conditions (although not greater than those contained currently contained in this Agreement) as shall be valid and enforceable under the applicable law.

of arbitration procedure then in effect. The parties consent to the jurisdiction to the federal courts of the District of Colorado or, if there shall be no jurisdiction, to the state courts
located in Arapahoe County, Colorado, to enforce any arbitration award rendered with respect thereto. Each party shall choose one arbitrator and the two arbitrators shall choose a third arbitrator. All costs and fees related to such arbitration (and
judicial enforcement proceedings, if any) shall be borne by the Company unless Employee’s claim is deemed to be frivolous by the arbitrator(s) or judge. 
 19. Legal Fees. The Company shall pay the reasonable expenses of Employee’s counsel in negotiating this Agreement. 
 20. Section 409A. Notwithstanding anything to the contrary in this Agreement, if Employee is a “specified employee” within the meaning of Section 409A of the Internal Revenue
Code of 1986, as amended (the “Code”) and the final regulations and any guidance promulgated thereunder (“Section 409A”) at the time of Employee’s termination (other than due to death), and the severance payable to Employee,
if any, pursuant to this Agreement, when considered together with any other severance payments or separation benefits which may be considered deferred compensation under Section 409A (together, the “Deferred Compensation Separation
Benefits”) will not and could not under any circumstances, regardless of when such termination occurs, be paid in full by March 15 of the year following Employee’s termination, then only that portion of the Deferred Compensation
Separation Benefits which do not exceed the Section 409A Limit (as defined below) may be made within the first six (6) months following Employee’s termination of employment in accordance with the payment schedule applicable to each
payment or benefit. For these purposes, each severance payment is hereby designated as a separate payment and will not collectively be treated as a single payment. Any portion of the Deferred Compensation Separation Benefits in excess of the
Section 409A Limit shall accrue and, to the extent such portion of the Deferred Compensation Separation Benefits would otherwise have been payable within the first six (6) months following Employee’s termination of employment, will
become payable on the first payroll date that occurs on or after the date six (6) months and one (1) day following the date of Employee’s termination. All subsequent Deferred Compensation Separation Benefits, if any, will be payable
in accordance with the payment schedule applicable to each payment or benefit. Notwithstanding anything herein to the contrary, if Employee dies following his termination but prior to the six (6) month anniversary of his termination, then any
payments delayed in accordance with this paragraph will be payable in a lump sum as soon as administratively practicable after the date of Employee’s death and all other Deferred Compensation Separation Benefits will be payable in accordance
with the payment schedule applicable to each payment or benefit. The foregoing provision is intended to comply with the requirements of Section 409A so that none of the severance payments and benefits to be provided hereunder will be subject to
the additional tax imposed under Section 409A, and any ambiguities herein will be interpreted to so comply. The Company and Employee agree to work together in good faith to consider amendments to this Agreement and to take such reasonable
actions which are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition prior to actual payment to Employee under Section 409A. For purposes of this Agreement, “Section 409A Limit” will
mean the lesser of two (2) times: (A) Employee’s annualized compensation based upon the annual rate of pay paid to Employee during the Company’s taxable year preceding the Company’s taxable year of Employee’s
termination of employment as determined under Treasury Regulation 1.409A-1(b)(9)(iii)(A)(1) and any Internal Revenue Service guidance issued with respect thereto; or (B) the maximum amount that may be taken into account under a qualified plan
pursuant to Section 401(a)(17) of the Code for the year in which Employee’s employment is terminated. 
 21. Application of
Internal Revenue Code Section 280G. If any payment or benefit Employee would receive pursuant to a Change in Control from the Company or otherwise (“Payment”) would (i) constitute a “parachute payment” within
the meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall be equal to the Reduced Amount. The
“Reduced Amount” shall be either (x) the largest portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax or (y) the largest portion, up to and including the total, of the Payment,
whichever amount, after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in Employee’s receipt, on an after-tax basis,
of the greater economic benefit notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in payments or benefits constituting “parachute payments” is necessary so that the Payment equals the
Reduced Amount, reduction shall occur in the manner that results in the greatest economic benefit for Employee. If more than one method of reduction will result in the same economic benefit, the items so reduced will be reduced pro rata. 

  
 5 

 In the event it is subsequently determined by the Internal Revenue Service that some portion of the Reduced
Amount as determined pursuant to clause (x) in the preceding paragraph is subject to the Excise Tax, Employee agrees to promptly return to the Company a sufficient amount of the Payment so that no portion of the Reduced Amount is subject to the
Excise Tax. For the avoidance of doubt, if the Reduced Amount is determined pursuant to clause (y) in the preceding paragraph, Employee will have no obligation to return any portion of the Payment pursuant to the preceding sentence. 

Unless Employee and the Company agree on an alternative accounting firm, the accounting firm engaged by the Company for general tax compliance purposes
as of the day prior to the effective date of the Change in Control shall perform the foregoing calculations. If the accounting firm so engaged by the Company is serving as accountant or auditor for the individual, entity or group effecting the
Change in Control, the Company shall appoint a nationally recognized accounting firm to make the determinations required hereunder. The Company shall bear all expenses with respect to the determinations by such accounting firm required to be made
hereunder. 
 The Company shall use commercially reasonable efforts to cause the accounting firm engaged to make the determinations hereunder to
provide its calculations, together with detailed supporting documentation, to the Employee and the Company within fifteen (15) calendar days after the date on which Employee’s right to a Payment is triggered (if requested at that time by
the Employee or the Company) or such other time as requested by Employee or the Company. 
 22. Indemnification. As a condition to the
effectiveness of this Agreement, the Company and Employee shall enter into a mutually acceptable indemnification agreement. 
 IN WITNESS
WHEREOF, the parties hereto have executed this Agreement as of the date first written above.
