written order of the Issuer, such order signed by one Officer, together with an Officers’ Certificate stating that all conditions precedent to such authentication have been satisfied.

securities, and in circumstances in which this Indenture provides for the Holders of Notes to vote or take any action, the Holders of Initial Notes and the Holders of any such Additional Notes will vote or take that action as a single class. 

Section 2.02. Form of Notes. The Notes and the Trustee’s certificate of authentication to be borne by such Notes shall be

 Any of the Notes may have such letters, numbers or other marks of identification and such notations, legends, endorsements or changes 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 by the Custodian or the Depositary or as may be
required for the Notes to be tradable on any market developed for trading of securities pursuant to Rule 144A or as may be required to comply with any applicable law or with any rule or regulation made pursuant thereto or with any rule or

exchanges, or transfers 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 or the Custodian, at the direction of

Notes) are registered at the Close of Business on a special record date for the payment of such Defaulted Interest, which shall be fixed in the following manner: The Issuer shall notify the Trustee in writing of the amount of Defaulted Interest
proposed to be paid on each Note and the date of the proposed payment (which shall be not less than 20 calendar days after the receipt by the Trustee of such notice), and at the same time the Issuer shall deposit with the Trustee an amount of
money equal to the aggregate amount to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in
trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Issuer shall fix a special record date for the payment of such Defaulted Interest which shall be not more than 15 calendar

obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Issuer shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and
that the Holder is entitled to the benefits of this Indenture. 
 In case any Officer who shall have signed any of the Notes shall cease to
be such Officer before the Notes so signed shall have been authenticated and delivered by the Trustee, or 

  
 14 








 
disposed of by the Issuer, such Notes nevertheless may be authenticated and delivered or disposed of as though the person who signed such Notes had not ceased to be such Officer, and any Note may

Register”) in which, subject to such reasonable regulations as it may prescribe, the Issuer shall provide for the registration of Notes and of transfers of Notes. The Note Register shall be in written form or in any form capable of being
exchanged into written form within a reasonably prompt period of time. The Trustee is hereby appointed “Note Registrar” for the purpose of registering Notes and transfers of Notes as herein provided. The Issuer may appoint one or
more co-registrars in accordance with Section 4.02. 
 Upon surrender for registration of
transfer of any Note to the Note Registrar or any co-registrar, and satisfaction of the requirements for such transfer set forth in this Section 2.05, the Issuer shall execute, and the Trustee shall

surrender of the Notes to be exchanged at any such office or agency maintained by the Issuer pursuant to Section 4.02. Whenever any Notes are so surrendered for exchange, the Issuer shall execute, and the Trustee shall authenticate and deliver,
the Notes which the Noteholder making the exchange is entitled to receive bearing registration numbers not contemporaneously outstanding. 

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

All Notes presented or surrendered for registration of transfer or for exchange or repurchase shall (if so required by the Issuer or the Note
Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Issuer and the Note Registrar, and the Notes shall be duly endorsed by the Noteholder thereof or its attorney duly
authorized in writing. 
 No service charge shall be made to any Holder for any registration of, transfer or exchange of Notes, but the
Issuer may require payment by the Holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes.

Default has occurred and is continuing and an election has been made to exchange such Notes. Any Global Note exchanged pursuant to clause (1) or (2) above shall be so exchanged in whole and not in part. Any Note issued in exchange for
a Global Note or any portion thereof shall be a Global Note; provided that any such Note so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Note. 

(iii) Notes issued in exchange for a Global Note or any portion thereof pursuant to clause (ii) above shall be issued in
definitive, fully registered form, without Interest coupons, shall have an aggregate principal amount equal to that of such Global Note or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations
as the Depositary shall designate and shall bear any legends required hereunder. Any Global Note to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Note Registrar. With regard to any Global Note to be exchanged in
part, either such Global Note shall be so surrendered for exchange or, if the Trustee is acting as Custodian for the Depositary or its nominee with respect to such Global Note, the principal amount thereof shall be reduced, by an amount equal to the
portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and make available for delivery the Note issuable on such exchange to

(v) Neither any members of, or participants in, the Depositary (“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, and the Depositary or such nominee, as the case may be, may be treated by
the Issuer, the Trustee and any agent of the Issuer 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 Issuer, the Trustee or any agent of
the Issuer or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, 

  
 16 








 
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. 
 (vi) At such time as all interests in a Global Note have
been repurchased, exchanged, or canceled for Notes in certificated form, 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
Custodian. At any time prior to such cancellation, if any interest in a Global Note is repurchased, exchanged, or canceled for Notes in certificated form, the principal amount of such Global Note shall, in accordance with the standing procedures and
instructions existing between the Depositary and the Custodian, be appropriately reduced, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction. 

(c) Every Note (and all securities issued in exchange therefor or in substitution thereof) that bears or is required under this
Section 2.05(c) to bear the legend set forth in this Section 2.05(c) (the “Restricted Notes Legend”), and any Common Stock that bears or is required under this Section 2.05(c) to bear the Common Stock legend set forth
in this Section 2.05(c) (the “Common Stock Legend”) (collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.05(c) (including those set forth
in the legends below) unless such restrictions on transfer shall be waived by written consent of the Issuer, and the Holder of each such Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on
transfer. As used in this Section 2.05(c), the term “transfer” means any sale, pledge, loan, transfer or other disposition whatsoever of any Restricted Security or any interest therein. 

Until the Maturity Date for the Notes, every certificate evidencing the Notes shall bear a Restricted Notes Legend in substantially the
following form unless otherwise determined by the Issuer in writing, with written notice thereof to the Trustee: 
 THIS SECURITY HAS NOT
BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER AGREES THAT
IT WILL NOT RESELL OR OTHERWISE TRANSFER THE SECURITY EVIDENCED HEREBY, EXCEPT (A) TO THE ISSUER, EMPIRE STATE REALTY TRUST, INC. OR A SUBSIDIARY OF THE ISSUER; OR (B) TO A PERSON THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL
BUYER (AS DEFINED IN RULE 144A ADOPTED UNDER THE SECURITIES ACT) THAT IS PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF ANOTHER QUALIFIED INSTITUTIONAL BUYER AND TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON
RULE 144A, ALL IN COMPLIANCE WITH RULE 144A (IF AVAILABLE). 

  
 17 








 Until the date that is the later of (1) the date that is one year after the date of issuance
of shares of Common Stock upon exchange of a Note, or such other period of time as permitted by Rule 144 under the Securities Act or any successor provision thereto, and (2) such later date, if any, as may be required by applicable laws,
any stock certificate evidencing shares of Common Stock issued upon exchange of such Note shall bear legends referring to the restrictions on ownership and transfer set forth in the Charter and a Common Stock Legend in substantially the following
form unless such Common Stock has been sold pursuant to a registration statement that has been declared or become effective under the Securities Act (and which continues to be effective at the time of such transfer) or pursuant to Rule 144
under the Securities Act or any similar provision then in force, or unless otherwise determined by the Issuer in writing: 
 THIS SECURITY
HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER
AGREES (1) THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THE SECURITY EVIDENCED HEREBY, EXCEPT (A) TO EMPIRE STATE REALTY TRUST, INC. OR A SUBSIDIARY THEREOF; (B) UNDER A REGISTRATION STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER
THE SECURITIES ACT; (C) TO A PERSON THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A ADOPTED UNDER THE SECURITIES ACT) THAT IS PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF ANOTHER QUALIFIED
INSTITUTIONAL BUYER AND TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, ALL IN COMPLIANCE WITH RULE 144A (IF AVAILABLE); OR (D) UNDER ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS
OF THE SECURITIES ACT; AND (2) THAT IT WILL, PRIOR TO ANY TRANSFER OF THIS SECURITY, FURNISH TO THE TRANSFER AGENT AND EMPIRE STATE REALTY TRUST, INC. SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS MAY BE REQUIRED TO CONFIRM THAT
SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 

Any such shares of Common Stock as to which such restrictions on transfer shall have expired in accordance with their terms or as to which the
conditions for removal of the Common Stock Legend set forth therein have been satisfied may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the
Common Stock, be exchanged for a new certificate or certificates for a like number of shares of Common Stock, which shall not bear the Common Stock Legend required by this Section 2.05(c). 

(d) By its acceptance of any Note bearing the Restricted Notes Legend, each Holder of such Note acknowledges the restrictions on transfer of
such Note set forth in this Indenture and in the Restricted Notes Legend and agrees that it will transfer such Note only as provided in this Indenture and as permitted by applicable law. 

  
 18 








 (e) Any Restricted Securities purchased or owned by the Issuer or any Affiliate thereof may not
be resold by the Issuer or such Affiliate unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction which results in such Notes or Common Stock, as the
case may be, no longer being “restricted securities” (as defined under Rule 144). 
 (f) The Trustee shall have no
responsibility or obligation to any Agent Members or any other Person with respect to the accuracy of the books or records, or the acts or omissions, of the Depositary or its nominee or of any participant or member thereof, with respect to any
ownership interest in the Notes or with respect to the delivery to any Agent Member or other Person (other than the Depositary) of any notice or the payment of any amount, under or with respect to such Notes. All notices and communications to be
given to the Noteholders and all payments to be made to Noteholders under the Notes shall be given or made only to or upon the order of the registered Noteholders (which shall be the Depositary or its nominee in the case of a Global Note). The
rights of beneficial owners in any Global Note shall be exercised only through the Depositary subject to the customary procedures of the Depository. The Trustee may rely and shall be fully protected in relying upon information furnished by the
Depositary with respect to its Agent Members. 
 The Trustee shall have no obligation or duty to monitor, determine or inquire as to
compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Agent Members in any Global Indenture). 

Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen,
the Issuer in its discretion may execute, and upon its written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and make available for delivery, a new Note, bearing a number not contemporaneously
outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case, the applicant for a substituted Note shall furnish to the Issuer, to the Trustee and, if
applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction,
loss or theft, the applicant shall also furnish to the Issuer, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 

Following receipt by the Trustee or such authenticating agent, as the case may be, of satisfactory security or indemnity and evidence, as
described in the preceding paragraph, the Trustee or such authenticating agent may authenticate any such substituted Note and make available for delivery such Note. Upon the issuance of any substituted Note, the Issuer may require the payment by the
Holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Note which has matured or is about to mature or has been properly


  
 19 








 
tendered for repurchase on a Fundamental Change Repurchase Date (and not withdrawn) or is to be exchanged pursuant to this Indenture, shall become mutilated or be destroyed, lost or stolen, the
Issuer may, instead of issuing a substitute Note, pay or authorize the payment of or exchange or authorize the exchange of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such
payment or exchange shall furnish to the Issuer, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by
or in connection with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Issuer, the Trustee and, if applicable, any Paying Agent or Exchange Agent evidence to their satisfaction of the
destruction, loss or theft of such Note and of the ownership thereof. 
 Every substitute Note issued pursuant to the provisions of this
Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Issuer, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be
entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and
owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment or exchange or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies
notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or exchange or repurchase of negotiable instruments or other securities without their surrender. 

Section 2.07. Temporary Notes. Pending the preparation of Notes in certificated form, the Issuer may execute and the Trustee or an
authenticating agent appointed by the Trustee shall, upon the written request of the Issuer, authenticate and deliver temporary Notes. Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Notes in
certificated form, but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Issuer. Every such temporary Note shall be executed by the Issuer and authenticated by the Trustee or
such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Notes in certificated form. Without unreasonable delay, the Issuer will execute and deliver to the Trustee or such
authenticating agent Notes in certificated form and thereupon any or all temporary Notes may be surrendered in exchange therefor, at each office or agency maintained by the Issuer pursuant to Section 4.02 and the Trustee or such authenticating
agent shall authenticate and make available for delivery in exchange for such temporary Notes an equal aggregate principal amount of Notes in certificated form. Such exchange shall be made by the Issuer at its own expense and without any charge
therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Notes in certificated form authenticated and delivered hereunder. 

Section 2.08. Cancellation of Notes. All Notes surrendered for the purpose of payment, repurchase, exchange or registration of
transfer shall, if surrendered to the Issuer or any paying agent to whom Notes may be presented for payment (the “Paying Agent”) or Exchange Agent, which shall initially be the Trustee, or any Note Registrar, be surrendered to the
Trustee and promptly canceled by it or, if surrendered to the Trustee, shall be promptly canceled by it and no 

  
 20 








 
Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of such canceled Notes in accordance with its applicable
procedures. If the Issuer shall acquire any of the Notes, such acquisition shall not operate as a repurchase or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation. 

Section 2.09. CUSIP Numbers. The Issuer in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if
so, the Trustee shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as
printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Issuer shall promptly notify the Trustee in writing of any change in the “CUSIP” numbers. 

ARTICLE 3 
 REPURCHASE OF
NOTES 
 Section 3.01. Redemption of Notes. The Notes shall be redeemable by the Issuer prior to the Maturity Date pursuant to
Article 15. No sinking fund is provided for the Notes. 
 Section 3.02. Repurchase at Option of Holders Upon a Fundamental
Change. (a) If there shall occur a Fundamental Change at any time prior to the Maturity Date, then each Noteholder shall have the right, at such Holder’s option, to require the Issuer to repurchase all of such Holder’s Notes, or any
portion thereof that is a multiple of $1,000 principal amount, in cash, on a date (the “Fundamental Change Repurchase Date”) specified by the Issuer, which shall be no earlier than the 20th Business Day and no later than the
35th Business Day after the date of the Issuer Repurchase Notice related to such Fundamental Change, at a repurchase price equal to 100% of the principal amount of the Notes being repurchased, plus accrued and unpaid Interest, if any, to, but
excluding, the Fundamental Change Repurchase Date; provided, however, that if the Fundamental Change Repurchase Date falls after a Record Date and on or prior to the corresponding Interest Payment Date, the Issuer shall pay the full amount of
accrued and unpaid Interest, if any, on such Interest Payment Date to the Holder of record at the Close of Business on the corresponding Record Date, and the repurchase price will be 100% of the principal amount of the Notes to be repurchased. 

(b) Within 15 Business Days following the occurrence of a Fundamental Change, the Issuer will give or cause to be given to all Holders of
record on the date of the Fundamental Change (and to beneficial owners as required by applicable law) an Issuer Repurchase Notice as set forth in Section 3.03 with respect to such Fundamental Change. The Issuer shall also deliver a copy of the
Issuer Repurchase Notice to the Trustee and the Paying Agent at such time as it is given to Noteholders. 
 No failure of the Issuer to give
the foregoing notices and no defect therein shall limit the Noteholders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 3.02. 

  
 21 








 (c) For a Note to be repurchased at the option of the Holder pursuant to this
Section 3.02(c), the Holder must deliver to the Paying Agent, prior to the Close of Business on the second Business Day immediately preceding the Fundamental Change Repurchase Date, (i) a written notice of repurchase (the
“Fundamental Change Repurchase Notice”) in the form set forth on the reverse of the Note duly completed (if the Note is certificated) or stating the following (if the Note is represented by a Global Note): (a) the certificate
number of the Note that the Holder will deliver to be repurchased (if the Note is certificated) or that the relevant Fundamental Change Repurchase Notice complies with the appropriate Depositary procedures (if the Note is represented by a Global
Note), (b) the portion of the principal amount of the Note which the Holder will deliver to be repurchased, which portion must be in minimum principal amounts of $1,000 or an integral multiple of $1,000 (provided that the remaining
principal amount of Notes not subject to repurchase must be in an authorized denomination) and (c) that such Note shall be repurchased as of the Fundamental Change Repurchase Date pursuant to the terms and conditions specified in the Note and
in this Indenture; together with (ii) such Notes duly endorsed for transfer (if the Note if certificated) or book-entry transfer of such Note (if such Note is represented by a Global Note). The delivery of such Note to the Paying Agent with, or
at any time after delivery of, the Fundamental Change Repurchase Notice (together with all necessary endorsements) at the office of the Paying Agent shall be a condition to the receipt by the Holder of the repurchase price therefore;
provided, however, that such repurchase price shall be so paid pursuant to this Section 3.02 only if the Notes so delivered to the Paying Agent shall conform in all respects to the description thereof in the Fundamental Change
Repurchase Notice. All questions as to the validity, eligibility (including time of receipt) and acceptance of any Note for repurchase shall be determined by the Issuer, whose determination shall be final and binding absent manifest error. 

(d) The Issuer, if so requested, shall repurchase from the Holder thereof, pursuant to this Section 3.02, a portion of a Note, if the
minimum principal amount of such portion is $1,000 or a whole multiple of $1,000. Provisions of this Indenture that apply to the repurchase of all of a Note also apply to the repurchase of such portion of such Note. 

(e) Notwithstanding the foregoing, no Notes may be repurchased by the Issuer pursuant to this Section 3.02 if the principal amount of the
Notes has been accelerated, and such acceleration has not been rescinded or cured, on or prior to the relevant Fundamental Change Repurchase Date (except in the case of an acceleration resulting from a default by the Issuer in the payment of the
repurchase price pursuant to this Section 3.02 with respect to the Notes to be repurchased). 
 (f) The Paying Agent shall promptly
notify the Issuer of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof. 
 Any
repurchase by the Issuer contemplated pursuant to the provisions of this Section 3.02 shall be consummated by the delivery of the consideration to be received by the Holder on the later of (i) a date within two Business Days after the
book-entry transfer or delivery of the Notes to the Paying Agent and (ii) the Fundamental Change Repurchase Date. Payment of the repurchase price for a Note for which a Fundamental Change Repurchase Notice has been delivered and not withdrawn
is conditioned upon book-entry transfer in compliance with applicable Depositary procedures or delivery of the Notes, together with necessary endorsements, to the Paying Agent. 

  
 22 








 Section 3.03. Issuer Repurchase Notice. (a) The Issuer Repurchase Notice, as
provided in Section 3.03(b), shall be given to Holders in the event of a Fundamental Change, on or before the 15th Business Day after the occurrence of such a Fundamental Change as provided in Section 3.02(b) (the “Issuer
Repurchase Notice Date”). 
 (b) In connection with any repurchase of Notes, the Issuer shall, on the applicable Issuer
Repurchase Notice Date, give written notice to Holders (with a copy to the Trustee) setting forth information specified in this Section (in either case, the “Issuer Repurchase Notice”). 

Each Issuer Repurchase Notice shall: 

(i) state the events causing the Fundamental Change and the date thereof; 

(ii) state the procedures Holders must follow to require the Issuer to purchase their Notes and that Holders must exercise
their right to elect to repurchase prior to the Close of Business on the second Business Day immediately preceding the Fundamental Change Repurchase Date; 

(iii) state the repurchase price, and the Fundamental Change Repurchase Date; 

(iv) state the name and address of the Trustee, the Paying Agent and the Exchange Agent; 

(v) state the applicable Exchange Rate and any adjustments thereto; 

(vi) state that Notes must be surrendered to the Paying Agent to collect the repurchase price; 

(vii) state that a Holder may withdraw its Fundamental Change Repurchase Notice at any time prior to the Close of Business on
the second Business Day immediately prior to the Fundamental Change Repurchase Date by delivering a valid written notice of withdrawal in accordance with Section 3.04; 

(viii) state that Notes as to which the Fundamental Change Repurchase Notice has been given may be exchanged only if the
Fundamental Change Repurchase Notice is withdrawn in accordance with the terms of this Indenture; 
 (ix) state the amount of
Interest accrued and unpaid per $1,000 principal amount of Notes to, but excluding, the Fundamental Change Repurchase Date; 

(x) state that, unless the Issuer defaults in making payment of the repurchase price, Interest on Notes covered by any
Fundamental Change Repurchase Notice shall cease to accrue on and after the Fundamental Change Repurchase Date; 

  
 23 








 (xi) state the CUSIP number of the Notes, if CUSIP numbers are then in use; and

 (xii) if the Issuer determines that it will deduct and withhold from such amount otherwise deliverable to the Holder the
amount required to be deducted and withheld under applicable law, the Issuer will include with the Issuer Repurchase Notice a notice of that determination and of its intent to withhold. 

An Issuer Repurchase Notice may be given by the Issuer or, at the Issuer’s request, the Trustee shall give such Issuer Repurchase Notice
in the Issuer’s name and at the Issuer’s expense; provided that the text of the Issuer Repurchase Notice shall be prepared by the Issuer. 

If any of the Notes is represented by a Global Note, then the Issuer will modify such Issuer Repurchase Notice to the extent necessary to
accord with the applicable procedures of the Depositary that apply to the repurchase of Global Notes. 
 (c) The Issuer shall, to the extent
applicable, comply with the provisions of Rule 13e-4 and Rule 14e-1 (or any successor provision) under the Exchange Act that may be applicable at the time of
the repurchase of the Notes, file the related Schedule TO (or any successor schedule, form or report) under the Exchange Act and comply with all other applicable federal and state securities laws in connection with the repurchase of the Notes.
To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture relating to the Issuer’s obligations to purchase the Notes upon a Fundamental Change as a result of changes in such laws or
regulations after the date of this Indenture, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached our obligations under such provisions of this Indenture by virtue of such conflict. 

Section 3.04. Effect of Fundamental Change Repurchase Notice; Withdrawal. Upon receipt by the Paying Agent of the Fundamental
Change Repurchase Notice, the Holder of the Note in respect of which such Fundamental Change Repurchase Notice was given shall (unless such Repurchase Notice is validly withdrawn in accordance with this Section 3.04) thereafter be entitled to
receive solely the repurchase price with respect to such Note. Such repurchase price shall be paid to such Holder on the later of (x) the Fundamental Change Repurchase Date with respect to such Note (provided the Holder has satisfied the
conditions in Section 3.02) and (y) two Business Days after the time of book-entry transfer or delivery of such Note to the Paying Agent by the Holder thereof in the manner required by Section 3.02 on or after the Fundamental Change
Repurchase Date. 
 Notes in respect of which a Fundamental Change Repurchase Notice has been given by the Holder thereof may not be
exchanged pursuant to Article 13 hereof on or after the date of the delivery of such Repurchase Notice unless such Fundamental Change Repurchase Notice has first been validly withdrawn. 

A Fundamental Change Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the office of the Paying Agent
at any time prior to the Close of Business on the second Business Day immediately prior to the Fundamental Change Repurchase Date specifying: 

  
 24 








 (a) the name of the Holder; 

(b) the certificate number(s) of all withdrawn Notes in certificated form or that the notice of withdrawal complies with appropriate
Depositary procedures with respect to all withdrawn Notes represented by a Global Note; 
 (c) the principal amount of Notes with respect to
which such notice of withdrawal is being submitted, which must be an integral multiple of $1,000; and 
 (d) the principal amount of Notes,
if any, that remains subject to the original Fundamental Change Repurchase Notice and that has been or will be delivered for repurchase by the Issuer. 

If a Fundamental Change Repurchase Notice is properly withdrawn, the Issuer shall not be obligated to repurchase the Notes so withdrawn from
such Repurchase Notice. 
 Section 3.05. Deposit of Repurchase Price. (a) Prior to 11:00 a.m., New York City time, on
the Fundamental Change Repurchase Date, the Issuer shall deposit with the Paying Agent or, if the Issuer is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 4.04 an amount of cash (in immediately available
funds if deposited on the Fundamental Change Repurchase Date), sufficient to pay the aggregate repurchase price of all the Notes or portions thereof that are to be repurchased as of the Fundamental Change Repurchase Date. The Paying Agent shall have
no duty to calculate the amount of cash sufficient to pay such aggregate repurchase price. 
 (b) If on the Fundamental Change Repurchase
Date the Paying Agent holds money sufficient to pay the repurchase price of the Notes that Holders have elected to require the Issuer to repurchase in accordance with Section 3.02 and which have not been withdrawn in accordance with
Section 3.04, then, on the Fundamental Change Repurchase Date such Notes will cease to be outstanding, Interest will cease to accrue and all other rights of the Holders of such Notes will terminate, other than the right to receive the
repurchase price upon delivery or book-entry transfer of the Note. This will be the case whether or not book-entry transfer of the Note has been made or the Note has been delivered to the Paying Agent. 

Section 3.06. Notes Repurchased in Part. Upon presentation of any Note repurchased only in part, the Issuer shall execute and the
Trustee shall authenticate and make available for delivery to the Holder thereof, at the expense of the Issuer, a new Note or Notes in aggregate principal amount equal to the unrepurchased portion of the Notes presented (provided that the
unrepurchased portion of the Notes must be in an integral multiple of $1,000). 
 Section 3.07. Repayment to the Issuer. Subject
to Section 11.04, the Paying Agent shall return to the Issuer any cash that remains unclaimed, together with Interest, if any, thereon, held by them for the payment of the repurchase price; provided that to the extent that the aggregate
amount of cash deposited by the Issuer pursuant to Section 3.05 exceeds the aggregate repurchase price of the Notes or portions thereof which the Issuer is obligated to repurchase as of the Fundamental Change Repurchase Date then, unless
otherwise agreed in writing between the Issuer and the Paying Agent, promptly after the second Business Day following the Fundamental Change Repurchase Date, the Paying Agent shall return any such excess to the Issuer, together with Interest, if
any, thereon. 

  
 25 








 Section 3.08. Repurchase by a Third Party. Notwithstanding the foregoing provisions
of this Article 3, the Issuer shall not be required to repurchase, or to make an offer to repurchase, the Notes upon a Fundamental Change if a third party makes such an offer in the same manner, at the same time and otherwise in compliance with the
requirements for an offer made by the Issuer as set forth in this Article 3 and such third party repurchases all Notes properly surrendered and not validly withdrawn under its offer in the same manner, at the same time and otherwise in compliance
with the requirements for an offer made by the Issuer as set forth in this Article 3. 
 ARTICLE 4 

PARTICULAR COVENANTS OF THE ISSUER AND THE COMPANY 

Section 4.01. Payment of Principal and Interest. The Issuer covenants and agrees that it will duly and punctually pay or cause to
be paid when due the principal of (including the repurchase price upon repurchase pursuant to Article 3) and Interest on each of the Notes at the places, at the respective times and in the manner provided herein and in the Notes. 

Section 4.02. Maintenance of Office or Agency. The Issuer will maintain an office or agency where the Notes may be surrendered for
registration of transfer or exchange or for presentation for payment or for exchange or repurchase. As of the date of this Indenture, such office shall be the Corporate Trust Office of the Trustee and, at any other time, at such other address as the
Trustee may designate from time to time by notice to the Issuer. The Issuer will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency not designated or appointed by the Trustee. If at
any time the Issuer shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations and surrenders may be made at the Corporate Trust Office, and the Issuer hereby appoints
the Trustee as its agent to receive all such presentations and surrenders. 
 The Issuer may also from time to time designate co-registrars and one or more 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 Issuer of its obligation to maintain an office or agency for such purposes. The Issuer will give prompt written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency. 
 The Issuer hereby initially designates the Trustee as Paying Agent, Note
Registrar, Custodian and Exchange Agent and the Corporate Trust Office shall be considered as one such office or agency of the Issuer for each of the aforesaid purposes. 

Section 4.03. Appointments to Fill Vacancies in Trustee’s Office. The Issuer, whenever necessary to avoid or fill a vacancy
in the office of Trustee, will appoint, upon the terms and conditions and otherwise as provided in Section 7.08, a Trustee, so that there shall at all times be a Trustee hereunder. 

  
 26 








 Section 4.04. Provisions as to Paying Agent. (a) If the Issuer shall appoint a
Paying Agent other than the Trustee, or if the Trustee shall appoint such a Paying Agent, the Issuer will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the
provisions of this Section 4.04: 
 (i) that it will hold all sums held by it as such agent for the payment of the
principal of or Interest on the Notes (whether such sums have been paid to it by the Issuer or by any other obligor on the Notes) in trust for the benefit of the Holders of the Notes; 

(ii) that it will give the Trustee notice of any failure by the Issuer (or by any other obligor on the Notes) to make any
payment of the principal of or Interest on the Notes when the same shall be due and payable; and 
 (iii) that at any time
during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee all sums so held in trust. 

The Issuer shall, on or before each due date of the principal of or Interest on the Notes, deposit with the Paying Agent a sum (in funds which
are immediately available on the due date for such payment) sufficient to pay such principal or Interest and (unless such Paying Agent is the Trustee) the Issuer will promptly notify the Trustee of any failure to take such action; provided
that if such deposit is made on the due date, such deposit shall be received by the Paying Agent by 11:00 a.m. New York City time, on such date. 

(b) If the Issuer shall act as its own Paying Agent, it will, on or before each due date of the principal of or Interest on the Notes, set
aside, segregate and hold in trust for the benefit of the Holders of the Notes a sum sufficient to pay such principal and Interest so becoming due and will promptly notify the Trustee of any failure to take such action and of any failure by the
Issuer (or any other obligor under the Notes) to make any payment of the principal of or Interest on the Notes when the same shall become due and payable. 

(c) Anything in this Section 4.04 to the contrary notwithstanding, the Issuer may, at any time, for the purpose of obtaining a
satisfaction and discharge of this Indenture, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust by the Issuer or any Paying Agent hereunder as required by this Section 4.04, such sums to be held by the
Trustee upon the trusts herein contained and upon such payment by the Issuer or any Paying Agent to the Trustee, the Issuer or such Paying Agent shall be released from all further liability with respect to such sums. 

(d) Anything in this Section 4.04 to the contrary notwithstanding, the agreement to hold sums in trust as provided in this
Section 4.04 is subject to Section 11.02 and Section 11.03. 
 The Trustee shall not be responsible, legally or otherwise,
for the actions of any other Paying Agents (including the Issuer if acting as its own Paying Agent) and shall have no control of any funds held by such other Paying Agents. 

Section 4.05. Existence. Subject to Article 10, each of the Issuer and the Company will do or cause to be done all things
necessary to preserve and keep in full force and effect its existence all material rights and material franchises; provided, however, that neither the Issuer 

  
 27 








 
nor the Company shall be required to preserve any such right or franchise if the Board of Directors of the Issuer or the Company, as applicable, shall determine that the preservation thereof is
no longer desirable in the conduct of the business of the Issuer or the Company, as applicable. 
 Section 4.06. Rule 144A
Information Requirement. At any time the Issuer and the Company are not subject to Section 13 or 15(d) of the Exchange Act and if so required by Rule 144A the Company and the Issuer will promptly furnish to the Holders, beneficial

Notes and such shares pursuant to Rule 144A. 
 Section 4.07. Stay, Extension and Usury Laws. The Issuer and the Company
each 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 usury, stay or extension law wherever enacted, now or at any
time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Issuer and the Company each (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. 

Section 4.08. Compliance Certificate. The Issuer and the Company will deliver to the Trustee, within 120 days after the end of
each fiscal year, a brief certificate from the principal executive officer, principal financial officer or principal accounting officer of the Company as to his or her knowledge of the Issuer’s and the Company’s compliance with all
conditions and covenants under this Indenture and, in the event of any noncompliance, specifying such noncompliance and the nature and status thereof. For purposes of this Section 4.08, such compliance shall be determined without regard to any
period of grace or requirement of notice under this Indenture. 
 The Issuer and the Company will deliver to the Trustee, within 30 days
upon becoming aware of any default in the performance or observance of any covenant, agreement or condition contained in this Indenture an Officer’s Certificate specifying with particularity such default or Event of Default and further stating

Interest is payable to Holders of Notes, the Issuer will provide written notice (“Supplementary Interest Notice”) to the Trustee of its obligation to pay Supplementary Interest no later than 5 calendar days prior to the proposed
Interest Payment Date for Supplementary Interest, and the Supplementary Interest Notice shall set forth the amount of Supplementary Interest to be paid by the Issuer on such Interest Payment Date. The Trustee shall not at any time be under any duty
or responsibility to any Holder of Notes to determine the Supplementary Interest, or with respect to 
 the nature, extent or calculation of the amount of
Supplementary Interest when made, or with respect to the method employed in such calculation of the Supplementary Interest. 

  
 28 








 Section 4.10. [Reserved] 

Section 4.11. Reservation of Shares, Shares to Be Fully Paid; Compliance with Governmental Requirements; Listing of Common Stock.
The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for the exchange of the Notes as required by this Indenture from time to time
as such Notes are presented for exchange. 
 The Company covenants that all shares of Common Stock which may be issued upon exchange of
Notes will upon issue be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. 

The Company further covenants that, if at any time the Common Stock shall be listed on the New York Stock Exchange or any other national or
regional securities exchange or automated quotation system, the Company will, if permitted by the rules of such exchange or automated quotation system, list and keep listed, so long as the Common Stock shall be so listed on such exchange or
automated quotation system, all the Common Stock issuable upon exchange of the Notes; provided that if the rules of such exchange or automated quotation system permit the Company to defer the listing of such the Common Stock until the first
exchange of the Notes in accordance with the provisions of this Indenture, the Company covenants to list such Common Stock issuable upon exchange of the Notes in accordance with the requirements of such exchange or automated quotation system at such
time. 
 Section 4.12. Covenant as to the Maturity Date During a Registration Default. If the Maturity Date, a Redemption Date
or a Fundamental Change Repurchase Date for the Notes occurs and a Registration Default (as defined in the Registration Rights Agreement) exists on such date, in addition to any Additional Interest or Supplementary Interest otherwise payable, the
Issuer will make a cash payment to each Holder of Notes of an amount equal to 3.0% of the principal amount of the Notes outstanding and held by such Holder as of the Close of Business on the third Scheduled Trading Day immediately prior to the
Maturity Date, Redemption Date or Fundamental Change Repurchase Date, as applicable; provided, however, that no such amount shall be paid if the Issuer amends this Indenture prior to such date to irrevocably elect to settle exchanges of such
Notes solely via Cash Settlement. For the avoidance of doubt, subject to the immediately preceding proviso, should the Maturity Date, the Redemption Date or Fundamental Change Repurchase Date occur during a period in which a Registration
Default (as defined in the Registration Rights Agreement) exists, all record Holders of Notes outstanding on the third Scheduled Trading Day immediately preceding the Maturity Date, the Redemption Date or the Fundamental Change Repurchase Date, as
applicable, will receive the cash payment specified in this paragraph regardless of whether their Notes have been exchanged on or after May 15, 2019 and prior to the Close of Business on such third Scheduled Trading Day preceding the Maturity
Date, the Redemption Date or the Fundamental Change Repurchase Date, as applicable. 
 Section 4.13. Company Guarantee. The
Company agrees to not incur any indebtedness for borrowed money or guarantee any of the Issuer’s indebtedness for borrowed money (in each 

  
 29 








 
case other than Permitted Debt) without fully and unconditionally guaranteeing (subject to reasonable and customary exceptions) the Issuer’s obligations under this Indenture, including the
due and punctual payment of principal of and Interest on the Notes, whether at Stated Maturity, by declaration of acceleration, notice of repurchase or otherwise; provided that the Company will be released from its obligations under such
guarantee, and such guarantee will be terminated, to the extent the Company is subsequently no longer an obligor of indebtedness for borrowed money or a guarantor of any of Issuer’s indebtedness for borrowed money (in each case other than
Permitted Debt). The guarantee will be a senior unsecured obligation of the Company and will rank equally in right of payment with other senior unsecured obligations of the Company.

 Section 5.02. Preservation and Disclosure of Lists. Every
Holder of Notes, by receiving and holding the same, agrees with the Issuer and the Trustee that neither the Issuer nor the Trustee nor any Authenticating Agent nor any Paying Agent nor any Note Registrar shall be held accountable by reason of the

reason of mailing any material pursuant to a request made under TIA Section 312(b).

Section 5.04. Reports by Issuer and Company. Each of the Issuer and the Company will deliver to the Trustee, within 15 days after

 30 








 
the quarterly and annual reports and of the information, documents and other reports, if any, that it is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange

need be furnished to the Trustee at any time the Company is not the Issuer’s general partner. Any such report, information or document that the Issuer or Company files with the Commission through the EDGAR system (or any successor thereto) will
be deemed to be furnished to the Trustee for the purposes of this Section 5.06 at the time of such filing through the EDGAR system (or such successor thereto). 

Delivery of such reports, information and documents to the Trustee pursuant to this Section 5.04 is for informational purposes only, and
the Trustee’s receipt (or deemed receipt) thereof shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuer’s compliance with any of its covenants

 ARTICLE 6 

EVENTS OF DEFAULT; REMEDIES 

Section 6.01. Events of Default. 

(a) In case any one or more of the following (each, an “Event of Default”) (whatever the reason for such Event of Default and

 31 








 (7) default in the performance, or breach, of any other covenant or warranty of
the Issuer in this Indenture with respect to the Notes, and continuance of such default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Issuer by the Trustee or by the Holders of at least
25% in aggregate principal amount of the Notes then outstanding a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; 

(8) default under any bond, debenture, note, mortgage, indenture or instrument under which there may be issued or by which
there may be secured or evidenced any Recourse Indebtedness for money borrowed by the Issuer or the Company or by any Subsidiary of the Issuer, the repayment of which the Issuer or the Company has guaranteed or for which the Issuer or the Company is
directly responsible or liable as obligor or guarantor, having an aggregate principal amount outstanding of at least $50,000,000 (or its foreign currency equivalent), whether such indebtedness now exists or shall hereafter be created, which default
shall have resulted in such indebtedness becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable, without such indebtedness having been discharged, or such acceleration having been
rescinded or annulled, within the period specified in such instrument, continuance of such default or breach for a period of 30 days after there has been given, by registered or certified mail, to the Issuer by the Trustee or by the Holders of
at least 25% in aggregate principal amount of the Notes then outstanding a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; 

(9) the rendering against the Issuer, the Company, or any Significant Subsidiary of a final judgment for the payment of
$50,000,000 (or its foreign currency equivalent) or more (excluding any amounts covered by insurance), which judgment is not discharged or stayed within 60 days after (i) the date on which the right to appeal thereof has expired if no such
appeal has commenced, or (ii) the date on which all rights to appeal have been extinguished; 
 (10) the Company, the
Issuer, or any Significant Subsidiary pursuant to or under or within meaning of any Bankruptcy Law: 
 (i) commences a
voluntary case; or 
 (ii) consents to the entry of an order for relief against it in an involuntary case; or 

(iii) consents to the appointment of any receiver, trustee, assignee, liquidator or other similar official under any Bankruptcy
Law of it or for all or substantially of its property; or 
 (iv) makes a general assignment for the benefit of creditors; or


  
 32 








 (11) a court of competent jurisdiction enters an order or decree under any
Bankruptcy Law that: 
 (i) is for relief against the Company, the Issuer or any of their respective Significant Subsidiaries
in an involuntary case; or 
 (ii) appoints a trustee, receiver, liquidator, custodian or other similar official of the
Company, the Issuer or any of their respective Significant Subsidiaries or for all or substantially all of its property; or 

(iii) orders the liquidation of the Company, the Issuer or any of their respective Significant Subsidiaries; 

and, in each case in this clause (11), the order or decree remains unstayed and in effect for 90 calendar days; 

then, and in each and every such case (other than an Event of Default specified in Section 6.01(a)(10) and Section 6.01(a)(11) with respect to the
Issuer or the Company), unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, by notice in writing to the
Issuer and the Company (and to the Trustee if given by Noteholders), may declare the principal amount of and Interest accrued and unpaid on all the Notes to be immediately due and payable, and upon any such declaration the same shall be immediately
due and payable. 
 If an Event of Default specified in Section 6.01(a)(10) or Section 6.01(a)(11) occurs with respect to the
Issuer or the Company and is continuing, then the principal amount of and Interest accrued and unpaid on all the Notes shall be immediately due and payable without any declaration or other action on the part of the Trustee or any Holder of Notes.

 (b) Notwithstanding any provisions of this Indenture to the contrary, if the Issuer so elects, the sole remedy for an Event of Default
relating to the Company’s failure to comply with Section 5.04 hereof (a “Reporting Event of Default”), will consist exclusively of the right to receive additional interest on the Notes at a rate equal to (i) 0.25% per
annum of the outstanding principal amount of the Notes for the first 180 days of the 270-day period in which such Event of Default is continuing beginning on, and including, the date on which such an
Event of Default first occurs and (ii) 0.50% per annum of the outstanding principal amount of the Notes for the last 90 days of such 270-day period as long as such Event of Default is continuing
(subject to Section 6.01(c), in addition to any Additional Interest that may be payable pursuant to the Registration Rights Agreement). 

If the Issuer so elects, such additional interest will be payable in the same manner and on the same dates as the stated Interest payable on
the Notes. On the 271st day after such Event of Default (if the Reporting Event of Default is not cured or waived prior to such 271st day), the Notes will be subject to acceleration pursuant to Section 6.01(a). The provisions of this
Section 6.01(b) will not affect the rights of Holders of Notes in the event of the occurrence of any Event of Default that is not a Reporting Event of Default. In the event the Issuer does not 

  
 33 








 
elect to pay the additional interest following a Reporting Event of Default in accordance with this Section 6.01(b) or the Issuer elected to make such payment but does not pay the additional
interest when due, the Notes will be subject to acceleration as provided in Section 6.01(a). 
 In order to elect to pay the additional
interest as the sole remedy during the first 270 days after the occurrence of a Reporting Event of Default, the Issuer must notify all Holders of Notes, the Trustee and the Paying Agent (if the Paying Agent is a Person other than the Trustee or the
Issuer) of such election prior to the beginning of such 270-day period. Upon the Issuer’s failure to timely give such notice, the Notes will be subject to acceleration as provided in Section 6.01(a).

 (c) In no event will the additional interest payable pursuant to Section 6.01(b) together with the Additional Interest payable
pursuant to the Registration Rights Agreement (collectively, the “Supplementary Interest”) accrue at a rate in excess of 0.50% per annum pursuant to the Indenture, regardless of the number of events or circumstances giving rise
to the requirement to pay such Supplementary Interest. 
 (d) If, at any time after the principal amount of and Interest on the Notes shall
have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, Holders of a majority in aggregate principal amount of the Notes then outstanding
on behalf of the Holders of all of the Notes then outstanding, by written notice to the Issuer and to the Trustee, may waive all defaults or Events of Default and rescind and annul such declaration and its consequences, subject in all respects to
Section 6.07, if: (a) all Events of Default, other than the nonpayment of the principal amount and any accrued and unpaid Interest that have become due solely because of such acceleration, have been cured or waived; (b) the Issuer or
the Company shall have deposited with the Trustee a sum sufficient to pay all overdue Interest, including Interest on overdue installments of Interest (to the extent that payment of such Interest is lawful), and principal which has become due
otherwise than by such declaration of acceleration; and (c) the Issuer has paid the Trustee its compensation and reimbursed the Trustee for its expenses (including any attorney’s reasonable fees), disbursements and advances pursuant to
Section 7.06. No such rescission and annulment shall extend to or shall affect any subsequent default or Event of Default, or shall impair any right consequent thereon. 

(e) In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or
abandoned because of such waiver or rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Issuer, the Holders of Notes, and the Trustee shall be restored respectively
to their several positions and rights hereunder, and all rights, remedies and powers of the Issuer, the Holders of Notes, and the Trustee shall continue as though no such proceeding had been taken. Notwithstanding the foregoing, the Trustee shall
retain all rights under this Indenture to be indemnified for expenses incurred related to such proceeding. 
 Section 6.02. Payments
of Notes on Default; Suit Therefor. The Issuer covenants that in the case of an Event of Default pursuant to Section 6.01(a)(1) or 6.01(a)(2), upon demand of the Trustee, the Issuer will pay to the Trustee, for the benefit of the Holders of
the Notes, (i) the whole amount that then shall be due and payable on all such Notes for principal or Interest, as 

  
 34 








 
the case may be, with Interest upon the overdue principal and (to the extent that payment of such Interest is enforceable under applicable law) upon the overdue installments of accrued and unpaid
Interest at the rate borne by the Notes from the required payment date and, (ii) in addition thereto, any amounts due the Trustee under this Indenture, including, but not limited to, Section 7.06. Until such demand by the Trustee, the
Issuer may pay the principal of and Interest on the Notes to the registered Holders, whether or not the Notes are overdue. 
 In case the
Issuer shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any actions or proceedings at law or in equity for the collection of the
sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against the Issuer or any other obligor on the Notes and collect in the manner provided by law out
of the property of the Issuer or any other obligor on the Notes wherever situated the monies adjudged or decreed to be payable. 
 In case
of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company, the Issuer or any other obligor upon the Notes or the property of
the Company, the Issuer or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the
Trustee shall have made any demand on the Issuer for the payment of overdue principal (including the repurchase price upon repurchase pursuant to Article 3)) shall be entitled and empowered, by intervention in such proceeding or otherwise:
(i) to file and prove a claim for the whole amount of principal (including the repurchase price upon repurchase pursuant to Article 3) and Interest owing and unpaid in respect of the Notes 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) and of the Holders of Notes allowed in such
judicial proceeding, and (ii) 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 other similar
official) in any such judicial proceeding is hereby authorized by each Holder of Notes 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 of Notes, to pay to
the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee and any predecessor Trustee, their agents and counsel, and any other amounts due the Trustee or any predecessor 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 of a Note 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 of Notes in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders of Notes, vote for the
election of a trustee in bankruptcy or similar official and may be a member of the creditors’ committee. 
 All rights of action and of
asserting claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or


  
 35 








 
proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes. 

In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes parties to any such proceedings. 

Section 6.03. Application of Monies Collected by Trustee. Any monies collected by the Trustee pursuant to this Article 6,
shall be applied, in the following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if
fully paid: 
  

			
	FIRST:	  	To the payment of costs and expenses of collection, including all sums paid or advanced by the Trustee hereunder and the compensation, expenses and disbursements of the Trustee, its agents and counsel all other amounts due the
Trustee and any predecessor Trustee under Section 7.06;
		
	SECOND:	  	To the payment of the amounts then due and unpaid upon the Notes for principal (including the repurchase price upon repurchase pursuant to Article 3) and Interest, in respect of which or for the benefit of which such money has
been collected, ratably, without preference or priority of any kind, according to the aggregate amounts due and payable on the Notes for principal (including the repurchase price upon repurchase pursuant to Article 3) and Interest,
respectively; and
		
	THIRD:	  	To the payment of the remainder, if any, to the Issuer.

 Section 6.04. Proceedings by Noteholders. No Holder of any Note shall have any right by virtue of
or by reference to any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture or the Notes, or for the appointment of a receiver, trustee, liquidator, custodian or
other similar official, or for any other remedy hereunder or the Notes, except in the case of a default in the payment of principal or Interest on the Notes, unless (a) such Holder previously shall have given to the Trustee written notice of an
Event of Default and of the continuance thereof, as hereinbefore provided, (b) the Holders of at least 25% in aggregate principal amount of the Notes then outstanding shall have made written request upon the Trustee to institute such action,
suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee indemnity or security as is satisfactory to the Trustee, (c) the Trustee for 60 calendar days after its receipt of such notice, request and offer of
such indemnity and security, shall have failed to institute any such action, suit or proceeding and (d) no direction inconsistent with such written request shall have been given to the Trustee by Holders of a majority in aggregate principal
amount of Notes then outstanding in accordance with Section 6.07; it being understood and intended, and being expressly covenanted by the taker and Holder of every Note with every other taker and Holder and the Trustee, that no 

  
 36 








 
one or more Holders of Notes shall have any right in any manner whatever by virtue of or by reference to any provision of this Indenture to affect, disturb or prejudice the rights of any other
Holder of Notes, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders of
Notes (except as otherwise provided herein). For the protection and enforcement of this Section 6.04, each and every Noteholder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 

Notwithstanding any other provision of this Indenture and any provision of any Note, the right of any Holder of any Note to receive payment of
the principal of (including the repurchase price upon repurchase pursuant to Article 3) and accrued Interest on such Note, on or after the respective due dates expressed in such Note or in the event of repurchase, or to institute suit for the
enforcement of any such payment on or after such respective dates against the Issuer shall not be impaired or affected without the consent of such Holder. 

Anything contained in this Indenture or the Notes to the contrary notwithstanding, the Holder of any Note, without the consent of either the
Trustee or the Holder of any other Note, in its own behalf and for its own benefit, may enforce, and may institute and maintain any proceeding suitable to enforce, its rights of exchange as provided herein. 

Section 6.05. Proceedings by Trustee. If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed
to protect and enforce its rights and the rights of the Holders of Notes by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant
or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. 

Section 6.06. Remedies Cumulative and Continuing. All powers and remedies given by this Article 6 to the Trustee or to the
Noteholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders of the Notes, by judicial proceedings or otherwise, to enforce the
performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any Holder of any of the Notes to exercise any right or power accruing upon any default or Event of Default
occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such default or any acquiescence therein, and, subject to the provisions of Section 6.04, every power and remedy given by
this Article 6 or by law to the Trustee or to the Noteholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Noteholders. 

Section 6.07. Direction of Proceedings and Waiver of Defaults by Majority of Noteholders. The Holders of not less than a majority
in aggregate principal amount of the Notes at the time outstanding shall have the right to direct, in writing, the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred
on the Trustee; provided that (a) such direction shall not be in conflict with any rule of law or with this Indenture, (b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such
direction, and (c) the Trustee need not take any 

  
 37 








 
action which might involve it in personal liability or be unduly prejudicial to the Holders of Notes not joining therein, it being understood that (subject to Section 7.02) the Trustee shall
have no duty to ascertain whether or not such actions or forbearance are unduly prejudicial to such Holders. 
 The Holders of a majority in
aggregate principal amount of the Notes at the time outstanding may, on behalf of the Holders of all of the Notes, waive any past default or Event of Default hereunder and its consequences except (i) a default in the payment of the
principal of or Interest on the Notes, (ii) a failure by the Issuer to exchange any Notes as required by this Indenture, (iii) a default in the payment of the repurchase price on the Fundamental Change Repurchase Date pursuant to
Article 3 or (iv) a default in respect of a covenant or provisions hereof, which under Article 9 cannot be modified or amended without the consent of the Holders of all Notes then outstanding or each Note affected thereby. 

Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for
every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. 

Section 6.08. Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder of any Note by its acceptance thereof
shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such
suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 6.08 (to the extent permitted by law) shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding determined in accordance with Section 8.04, or to any suit instituted by
any Noteholder for the enforcement of the payment of the principal of (including the repurchase price upon repurchase pursuant to Article 3), or Interest on any Note on or after the due date expressed in such Note or to any suit for the
enforcement of the right to exchange any Note in accordance with the provisions of Article 13. 
 ARTICLE 7 

THE TRUSTEE 
 Section 7.01.

Section 313(c), notice of such default hereunder known to a Responsible Officer of the Trustee, unless such default shall have been cured or waived pursuant to the terms of Section 6.07 hereof; provided, however, that, except in the
case of a default in the payment of the principal of (including the repurchase price upon repurchase pursuant to Article 3) or Interest on any Note, the Trustee shall be protected in withholding such notice if and so long as Responsible
Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Holders of the Notes; and 

  
 38 








 
provided further that in the case of any default or breach of the character specified in Section 6.01(a)(7), no such notice to Holders of Notes shall be given until at least 60 days
after the occurrence thereof. As used herein, the term “actual knowledge” means the actual fact or statement of knowing, without any duty to make any investigation with regard thereto. 

Section 7.02. Certain Rights of Trustee. Subject to the provisions of TIA Section 315(a) through 315(d): 

(a) the Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, Officer’s Certificate,
certificate, statement, instrument, Opinion of Counsel, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon or other paper or document believed by it to be genuine and to have been signed or presented by the
proper party or parties; 
 (b) any request or direction of the Issuer mentioned herein shall be sufficiently evidenced by an Issuer Request
or Issuer Order (other than delivery of any Note to the Trustee for authentication and delivery pursuant to Sections 2.01 and 2.04 which shall be sufficiently evidenced as provided therein) and any resolution of the Board of Directors may be
sufficiently evidenced by a Board Resolution; 
 (c) whenever in the administration of this Indenture the Trustee shall deem it desirable
that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officer’s
Certificate and/or an Opinion of Counsel; 
 (d) before the Trustee acts or refrains from acting, the Trustee may consult with counsel and
the written advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon; 

(e) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or
direction of any of the Holders of Notes pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which might be incurred by it in
compliance with such request or direction; 
 (f) the Trustee shall not be bound to make any investigation into the facts or matters
stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon or other paper or document, unless requested in writing so to do by the Holders of not less than
a majority in aggregate principal amount of the outstanding Notes; 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 indemnity satisfactory to it against such expenses or liabilities as a condition to
proceeding; the reasonable expenses of every such examination shall be paid by the Holders or, if paid by the Trustee, shall be repaid by the Holders upon demand. The Trustee, in its discretion, may, but shall not be 


  
 39 








 
required to, make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall
be entitled to examine the books, records and premises of the Issuer, relevant to the facts or matters that are the subject of its inquiry, personally or by agent or attorney; 

(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 and the Trustee shall not be responsible for any willful misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder; 

(h) the Trustee shall not be liable for any action taken, suffered or omitted by it in good faith and reasonably believed by it to be
authorized or within the discretion or rights or powers conferred upon it by this Indenture; 
 (i) if any party fails to deliver a notice
relating to an event the fact of which, pursuant to this Indenture, requires notice to be sent to the Trustee, the Trustee (to the extent that a Responsible Officer of the Trustee does not have actual knowledge of the existence of such event or fact
) may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred; 
 (j) the Trustee shall not be
required to give any bond or surety in respect of the performance of its powers and duties hereunder; 
 (k) the permissive rights of the
Trustee to do things enumerated in this Indenture shall not be construed as a duty and the Trustee shall not be answerable for other than its negligence or willful misconduct; and 

(l) the Trustee shall not be responsible or liable for punitive, 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 actions; 

(m) the Trustee shall not be responsible or liable for any failure or delay in the performance of its obligations under this Indenture arising
out of or caused, directly or indirectly, by circumstances beyond its reasonable control, including, without limitation, acts of God; earthquakes; fire; flood; terrorism; wars and other military disturbances; sabotage; epidemics; riots;
interruptions; loss or malfunction of utilities, computer (hardware or software) or communication services; accidents; labor disputes; and acts of civil or military authorities and governmental action; and 

(n) except for (i) a default under Sections 6.01(a)(1) or 6.01(a)(2) hereof, or (ii) any other event of which a Responsible
Officer of the Trustee has “actual knowledge” and which event, with the giving of notice or the passage of time or both, would constitute an Event of Default under this Indenture, the Trustee shall not be deemed to have notice of any
default or Event of Default unless specifically notified in writing of such event by the Issuer or the Holders of not less than 25% in aggregate principal amount of the Notes then outstanding. 

  
 40 








 Notwithstanding anything to the contrary herein, the Trustee shall not be required to expend or
risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it. Except during the continuance of an Event of Default, the Trustee undertakes to perform only such duties as are specifically set forth in this Indenture, and no implied
covenants or obligations shall be read into this Indenture against the Trustee. 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 (including as Paying Agent, Note Registrar, Custodian, Exchange Agent and Bid Solicitation Agent), and each agent, custodian and other Person employed to act hereunder. 

Section 7.03. Not Responsible for Recitals or Issuance of Notes. The recitals contained herein and in the Notes, except the
Trustee’s certificate of authentication, shall be taken as the statements of the Issuer, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the
validity or sufficiency of this Indenture or of the Notes except that the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Notes and perform its obligations hereunder. Neither the Trustee nor any
Authenticating Agent shall be accountable for the use or application by the Issuer of Notes or the proceeds thereof. 
 Section 7.04.
May Hold Notes and Common Stock. The Trustee, any Paying Agent, Exchange Agent, Note Registrar, Authenticating Agent or any other agent of the Issuer, in its individual or any other capacity, may become the owner or pledgee of Notes or
Common Stock and, subject to TIA Sections 310(b) and 311, may otherwise deal with the Issuer and the Company with the same rights it would have if it were not Trustee, Paying Agent, Exchange Agent, Note Registrar, Authenticating Agent or such
other agent. 
 Section 7.05. Money Held in Trust. Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed with the Issuer. 

Section 7.06. Compensation and Reimbursement. The Issuer agrees: 

(a) to pay to the Trustee from time to time, and the Trustee shall be entitled to, compensation for all services rendered by it hereunder
(which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); 
 (b)
except as otherwise expressly provided herein, to pay or reimburse each of the Trustee and any predecessor Trustee upon its request for all expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this
Indenture (including the compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its gross negligence or willful misconduct; and 

  
 41 








 (c) to indemnify each of the Trustee and any predecessor Trustee and their respective officers,
directors, employees and agents (each, an “Indemnified Person”) for, and to hold each of them harmless against, any loss, liability or expense incurred without gross negligence or willful misconduct on such Indemnified Person’s
part, arising out of or in connection with the acceptance or administration of this Indenture, including the costs and expenses of defending itself against or investigating any claim or liability in connection with the exercise or performance of any
of its powers or duties hereunder and including claims against or brought by the Issuer or the Company. 
 When the Trustee incurs expenses
or renders services in connection with an Event of Default specified in Sections 6.01(a)(10) or 6.01(a)(11), the expenses (including the 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. 
 As security for the
performance of the obligations of the Issuer under this Section, the Trustee shall have a lien prior to the Notes upon all property and funds held or collected by the Trustee as such, except funds held in trust for the payment of principal of
(including the repurchase price upon repurchase pursuant to Article 3) or Interest on any Notes. The provisions of this Section shall survive the discharge or termination of this Indenture and the earlier resignation or removal of the
Trustee. 
 Section 7.07. Corporate Trustee Required; Eligibility; Conflicting Interests. There shall at all times be a Trustee
hereunder which shall be eligible to act as Trustee under TIA Section 310(a)(1) and shall have a combined capital and surplus of at least $50,000,000. If such corporation publishes reports of condition at least annually, pursuant to law or the
requirements of Federal, state, territorial or District of Columbia supervising or examining authority, then for the purposes of this Section, 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. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article. The Trustee shall comply with the provisions of Section 310(b) of the Trustee Indenture Act. Neither the Issuer nor any Person directly or indirectly controlling, controlled by, or under common control
with the Issuer shall serve as Trustee. 
 If and when the Trustee shall be or become a creditor of the Issuer or the Company or any other
obligor under the Notes, the Trustee shall be subject to the provisions of the TIA regarding the collection of claims against the Issuer or the Company (or any such other obligor). 

Section 7.08. Resignation and Removal; Appointment of Successor. 

(a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective
until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 7.09. 

  
 42 








 (b) The Trustee may resign at any time by giving written notice thereof to the Issuer. If an
instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of
a successor Trustee. 
 (c) The Trustee may be removed at any time by Act of the Holders of a majority in principal amount of the
Outstanding Notes delivered to the Trustee and to the Issuer. 
 (d) If at any time: 

(i) the Trustee shall fail to comply with the provisions of TIA Section 310(b) after written request therefor by the
Issuer or by any Holder of a Note who has been a bona fide Holder of a Note for at least six months, or 
 (ii) the Trustee
shall cease to be eligible under Section 7.07 of this Indenture and shall fail to resign after written request therefor by the Issuer or by any Holder of a Note who has been a bona fide Holder of a Note for at least six months, or 

(iii) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver 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, 

then, in any such case, (a) the Issuer by or pursuant to a Board Resolution may remove the Trustee and appoint a successor Trustee, or (b) subject
to TIA Section 315(e), any Holder of a Note 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 or Trustees. 
 (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, the Issuer, by or pursuant to a Board Resolution, shall promptly appoint a successor Trustee or Trustees. If, within one year after such resignation, removal or
incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in principal amount of the outstanding Notes delivered to the Issuer and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee and to that extent supersede the successor Trustee appointed by the Issuer. If no successor Trustee shall have been so appointed by the Issuer or the
Holders of Notes and accepted appointment in the manner hereinafter provided, any Holder of a Note 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 appointment of a successor Trustee. 
 (f) The Issuer shall give notice of each resignation and each removal
of the Trustee and each appointment of a successor Trustee by mailing or causing to be mailed such notice to the Holders of Notes as they appear on the Note Register. Each notice shall include the name of the successor Trustee and the address of its
Corporate Trust Office. 

  
 43 








 Section 7.09. Acceptance of Appointment By Successor. (a) In case of the
appointment hereunder of a successor Trustee, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Issuer and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or
removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on request of the Issuer
or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee, and shall duly assign, transfer
and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder, subject nevertheless to its claim, if any, provided for in Section 7.06. 

(b) In case of the appointment hereunder of a successor Trustee, the Issuer, the retiring Trustee and each successor Trustee shall execute and
deliver an indenture supplemental hereto, pursuant to Article Nine hereof, wherein each successor Trustee shall accept such appointment and which (i) shall contain such provisions as shall be necessary or desirable to transfer and confirm to,
and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee to which the appointment of such successor Trustee relates, (ii) if the retiring Trustee is not retiring all Notes, shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(iii) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such
supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts
hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor
Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trust sand duties of the retiring Trustee to which the appointment of such successor Trustee relates; but, on request of the Issuer or any
successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder to which the appointment of such successor Trustee relates. 

(c) Upon request of any such successor Trustee, the Issuer shall execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (a) or (b) of this Section 7.09, as the case may be. 

(d) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and
eligible under this Article. 
 Section 7.10. Merger, Conversion, Consolidation or Succession to Business. Any corporation into
which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially
all of the 

  
 44 








 
corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without
the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Notes shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation
to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes. In case any Notes shall not have been authenticated by such
predecessor Trustee, any such successor Trustee may authenticate and deliver such Notes, in either its own name or that of its predecessor Trustee, with the full force and effect which this Indenture provides for the certificate of authentication of
the Trustee. 
 Section 7.11. Appointment of Authenticating Agent. At any time when any of the Notes remain outstanding, the
Trustee may appoint an Authenticating Agent or Agents which shall be authorized to act on behalf of the Trustee to authenticate Notes issued upon exchange, registration of transfer or partial repayment thereof, and Notes so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Any such appointment shall be evidenced by an instrument in writing signed by a Responsible Officer of the
Trustee, a copy of which instrument shall be promptly furnished to the Issuer. Wherever reference is made in this Indenture to the authentication and delivery of Notes by the Trustee or the Trustee’s certificate of authentication, such
reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Issuer and shall at all times be a bank or trust company or corporation organized and doing business and in good standing under the laws of the United States of America or of any state or the District of Columbia, authorized under
such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or state authorities. If such Authenticating Agent publishes reports of condition at
least annually, pursuant to law or the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent 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 an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign
immediately in the manner and with the effect specified in this Section. 
 Any corporation into which an Authenticating Agent may be merged
or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate
trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or further act on the part of the
Trustee or the Authenticating Agent. 
 An Authenticating Agent may at any time resign by giving written notice of resignation to the
Trustee and to the Issuer. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice of termination to such Authenticating Agent and to the Issuer. Upon receiving such a notice of resignation or upon such a
termination, or in case 

  
 45 








 
at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be
acceptable to the Issuer and shall give notice of such appointment to all Holders of Notes by mailing or causing to be mailed such notice to the Holders of Notes as they appear on the Note Register. Any successor Authenticating Agent upon acceptance
of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent herein. No successor Authenticating Agent shall be appointed
unless eligible under the provisions of this Section. 
 The Issuer agrees to pay to each Authenticating Agent from time to time reasonable
compensation including reimbursement of its reasonable expenses for its services under this Section. 
 If an appointment is made pursuant
to this Section, the Notes may have endorsed thereon, in addition to or in lieu of the Trustee’s certificate of authentication, an alternate certificate of authentication substantially in the following form: 

This is one of the Notes designated therein referred to in the within-mentioned Indenture.

 Section 7.12. Certain Duties and Responsibilities of the Trustee. 

(a) With respect to the Notes, except during the continuance of an Event of Default with respect to the Notes: 

(i) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and
imposed by the Trust Indenture Act and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 

(ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions 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, but shall not be under any duty to verify the contents or
accuracy thereof. 

  
 46 








 (b) In case an Event of Default has occurred and is continuing, 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. 

(c) 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: 
 (i) this Subsection shall not be construed to limit the effect
of Subsection (a) of this Section; 
 (ii) the Trustee shall not be liable for any error of judgment made in good faith
by a Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; 

(iii) 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 of a majority in principal amount of the outstanding Notes 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; and 
 (iv) no provision of this Indenture shall require the Trustee to expend or risk its
own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it. 
 (d) Whether or not therein expressly so provided, every
provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 7.12. 

ARTICLE 8 
 THE NOTEHOLDERS

 Section 8.01. Action by Noteholders. Whenever in this Indenture it is provided that the Holders of a specified percentage in
aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the
Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Noteholders in person or by agent or proxy appointed in writing, or (b) by the record
of the Holders of Notes voting in favor thereof at any meeting of Noteholders, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Noteholders. Whenever the Issuer or the Trustee solicits the
taking of any action by the Holders of the Notes, the Issuer or the Trustee may fix in advance of such solicitation a date as the record date for determining Holders entitled to take such action. Notwithstanding Trust Indenture Act
Section 316(c), such record date shall be the record date 

  
 47 








 
specified in or pursuant to such Board Resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation of Noteholders generally in connection therewith and not
later than the date such solicitation is completed. 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 Noteholders of
record at the Close of Business on such record date shall be deemed to be Noteholders for the purposes of determining whether Holders of the requisite proportion of outstanding Notes have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other act, and for that purpose the outstanding Notes shall be computed as of such record date; provided that no such authorization, agreement or consent by the Noteholders on such record
date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than eleven months after the record date. 

Section 8.02. Proof of Execution by Noteholders. Subject to the provisions of Sections 7.02 and 7.12, proof of the execution
of any instrument by a Noteholder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding
of Notes shall be proved by the registry of such Notes or by a certificate of the Note Registrar. 
 Section 8.03. Absolute
Owners. The Issuer, the Trustee, any Paying Agent, any exchange agent and any Note Registrar may deem the Person in whose name such Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of such Note
(whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other than the Issuer or any Note Registrar) for the purpose of receiving payment of or on account of the principal
of (including the repurchase price upon repurchase pursuant to Article 3) and Interest on such Note, for exchange of such Note and for all other purposes; and neither the Issuer nor the Trustee nor any Paying Agent nor any exchange agent nor
any Note Registrar shall be affected by any notice to the contrary. All such payments so made to any Holder for the time being, or upon its order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the
liability for monies payable upon any such Note. 
 Section 8.04. Issuer-Owned Notes Disregarded. In determining whether the
Holders of the requisite aggregate principal amount of Notes have given any request, demand, authorization, direction, notice, consent or waiver under this Indenture or whether a quorum is present at a meeting of Noteholders, Notes which are owned
by the Issuer or any other obligor upon the Notes or any Affiliate of the Issuer or any other obligor on the Notes, as such ownership shall be reflected on the Note Register, shall be disregarded and deemed not to be outstanding for the purpose of
any such determination, except that for purposes of determining whether the Trustee shall be protected in relying upon any such request, demand, authorization, direction, notice, consent or waiver thereunder or whether a quorum is present at a
meeting of holders of Notes, only Notes that the Trustee actually knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith may be regarded as outstanding for the purposes of this Section 8.04 if the
pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to vote such Notes and that the pledgee is not the Issuer, any other obligor on the Notes or any Affiliate of the Issuer or any such other obligor. In the case of a
dispute as to such right, any

Article 9 shall comply with the Trust Indenture Act, as then in effect, provided that this Section 9.03 shall not require such supplemental indenture or the Trustee to be qualified under the Trust Indenture Act prior to the time, if
ever, such qualification is in fact required under the terms of the Trust Indenture Act or the Indenture has been qualified under the Trust Indenture Act, 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, if ever, such qualification is in fact required under the terms of the Trust Indenture Act or the Indenture has been qualified under the Trust Indenture Act. Upon the execution of

amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes. 

Section 9.04. Notation on Notes. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to
the provisions of this Article 9 may bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Issuer or the Trustee shall so determine, new Notes so modified as to conform, in the
opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture may, at the Issuer’s expense, be prepared and executed by the Issuer, authenticated by the Trustee (or an
authenticating agent duly appointed by the Trustee pursuant to Section 7.11) and delivered in exchange for the Notes then outstanding, upon surrender of such Notes then outstanding. 

Section 9.05. Evidence of Compliance of Supplemental Indenture to Be Furnished to Trustee. Prior to entering into any

ARTICLE 11 
 SATISFACTION AND
DISCHARGE OF INDENTURE 
 Section 11.01. Satisfaction and Discharge of Indenture. This Indenture shall cease to be of further
effect (except as to (i) rights hereunder of Holders of the Notes to receive all amounts owing upon the Notes and the other rights, duties and obligations of Holders of the Notes, as beneficiaries hereof with respect to the amounts, if any, so
deposited with the Trustee and (ii) the rights, obligations and immunities of the Trustee hereunder), and the Trustee, upon demand of and at the expense of the Issuer, shall execute instruments in form and substance satisfactory to the Trustee
and the Issuer acknowledging satisfaction and discharge of this Indenture when: 
 (a) either 

(i) all Notes theretofore authenticated and delivered (other than (a) Notes which have been destroyed, lost or stolen and
which have been replaced or paid as provided in Section 11.04, and (b) Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged
from such trust, as provided in Section 11.04) have been delivered to the Trustee for cancellation; or 
 (ii) all such
Notes not theretofore delivered to the Trustee for cancellation have become due and payable, and the Issuer has irrevocably deposited or caused to be deposited with the Trustee, a Paying Agent or the Exchange Agent (other than the Issuer or any of
its Affiliates), as applicable, as trust funds in trust cash and/or shares of Common Stock (as applicable under the terms of this Indenture) in an amount sufficient to pay and discharge (without the necessity of investing such amount of cash
deposited) the entire indebtedness on such Notes not theretofore delivered to the Trustee for cancellation, for principal and Interest to the date of such deposit (in the case of Notes which have become due and payable) or to the Stated Maturity,
Fundamental Change Repurchase Date or Redemption Date, as the case may be; 

  
 54 








 (b) the Issuer has paid or caused to be paid all other sums payable hereunder by the Issuer; and

 (c) the Issuer has delivered to the Trustee an Officer’s’ Certificate and an Opinion of Counsel, each stating that all
conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with. 

Section 11.02. Application of Trust Funds. All money deposited with the Trustee pursuant to Section 11.01 shall be held in
trust, uninvested, and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as its own Paying Agent) as the Trustee may determine,
to the Persons entitled thereto, of the principal and any Interest for whose payment such money has been deposited with or received by the Trustee, but such money need not be segregated from other funds except to the extent required by law. All
moneys deposited with the Trustee (and held by it or any Paying Agent) for the payment of Notes subsequently exchanged shall be returned to the Issuer upon request. 

Section 11.03. Return of Unclaimed Monies. Subject to the restrictions of applicable law, the Trustee and each Paying Agent shall
pay to the Issuer upon request any money held by them for the payment of principal or Interest that remains unclaimed for two years after a right to such money has matured. After payment to the Issuer, Holders entitled to money must look to the
Issuer for payment as general creditors unless an applicable abandoned property law designates another person, and the Trustee and each Paying Agent shall be relieved of all liability with respect to such money. 

Section 11.04. Reinstatement. If the Trustee or the Paying Agent is unable to apply any money in accordance with this
Article 11 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuer’s obligations under this Indenture and the Notes shall be revived and
reinstated as though no deposit had occurred pursuant to this Article 11 until such time as the Trustee or Paying Agent is permitted to apply all money held in trust with respect to the Notes; provided, however, that if the Issuer makes
any payment of principal of or Interest on any Notes following the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of the Notes to receive such payment from the money so held by the Trustee or Paying
Agent in trust.

manager, employee, officer, agent or director, solely in their capacity as such, of the Company or the Issuer, as applicable, or any such predecessor or successor, under any rule of law, statute or constitutional provision or by the enforcement of
any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the Notes by the Holders as part of the consideration for the issue of the Notes.

 ARTICLE 13 

EXCHANGE OF NOTES 

Section 13.01. Right to Exchange. (a) Subject to the restrictions on ownership of shares of Common Stock as set forth in
Section 13.06, and upon compliance with the provisions of this Article 13, a Holder may exchange, at such Holder’s option, all or part of its Notes, in multiples of $1,000, based on the Exchange Rate (the “Exchange
Obligation”), subject to the provisions of Section 13.02. Prior to the Close of Business on the Business Day immediately preceding May 15, 2019, Holders shall have the right to exchange their Notes only under the circumstances
described in Section 13.01(b). On or after May 15, 2019, a Holder may surrender its Notes for exchange at any time on or prior to the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date without
regard to the conditions in Section 13.01(b). In no event may Notes be surrendered for exchange after the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date. 

(b) (i) Prior to the Close of Business on the Business Day immediately preceding May 15, 2019, Notes may be surrendered for exchange on
any date during any calendar quarter beginning after September 30, 2014 (and only during such calendar quarter) if the Closing Sale Price of the Common Stock was more than 130% of the then current Exchange Price for at least 20 Trading
Days (whether or not consecutive) in the period of the 30 consecutive Trading Days ending on the last Trading Day of the previous calendar quarter. The Company shall determine at the beginning of each calendar quarter commencing after
September 30, 2014 whether the Notes may be surrendered for conversion in accordance with this clause (i) and shall notify the Exchange Agent (if other than the Trustee) and the Trustee as to whether or not the Notes become exchangeable in
accordance with this clause (i). 
 (ii) Prior to the Close of Business on the Business Day immediately preceding
May 15, 2019, Notes may be surrendered for exchange at any time during the five Business Day period immediately after any five consecutive Trading Day period in which the Trading Price per $1,000 principal amount of Notes, as determined
following a request by a Holder of Notes in accordance with this subsection (b)(ii), for each Trading Day of such five Trading Day period was less than 98% of the product of the Closing Sale Price of the Common Stock and the Exchange Rate on
each such Trading Day during such five Trading Day period. The Trading Prices shall be determined by the Bid Solicitation Agent pursuant to this subsection (b)(ii) and the definition of Trading Price set forth in this Indenture. The Issuer
shall provide written notice to the Bid Solicitation Agent of the three independent nationally recognized securities dealers selected by the Issuer pursuant to the definition of Trading Price, along with appropriate contact information for each. The
Bid Solicitation Agent shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes unless the Issuer has requested such determination in writing and provided it with the names and contact information of at least
three nationally recognized securities dealers; and the Issuer shall have no obligation to make such request unless a Holder provides the Issuer with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than


  
 56 








 
98% of the product of the Closing Sale Price of the Common Stock and the Exchange Rate, at which time, the Issuer shall instruct the Bid Solicitation Agent in writing to determine the Trading
Price per $1,000 principal amount of Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Closing Sale Price of
the Common Stock and the Exchange Rate. If the Issuer does not instruct the Bid Solicitation Agent to determine the Trading Price per $1,000 principal amount of Notes when obligated as provided in the preceding sentence, or if the Issuer instructs
the Bid Solicitation Agent to obtain bids and the Bid Solicitation Agent fails to make such determination, then, in either case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last
Reported Sale Price of the Common Stock and the Exchange Rate on each Trading Day of such failure. If the Trading Price condition set forth above has been met, the Issuer shall so notify the Holders, the Trustee and the Exchange Agent (if other than
the Trustee) in writing within one Business Day. If, at any time after the Trading Price condition set forth above has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Closing
Reported Sale Price of the Common Stock and the Exchange Rate for such Trading Day, the Issuer shall so notify the Holders of the Notes, the Trustee and the Exchange Agent (if other than the Trustee) in writing. 

(iii) If, prior to the Close of Business on the Business Day immediately preceding May 15, 2019, the Company: 

(A) distributes to all or substantially all holders of its Common Stock rights, options or warrants (other than any issuance of
any rights, options or warrants issued under a stockholder rights plan that are (i) transferable with shares of Common Stock, including upon conversion, and (ii) not exercisable until the occurrence of a triggering event; provided
that such rights, options or warrants will be deemed issued under this subclause (A) upon the separation of such rights, options or warrants from the Common Stock, or upon the occurrence of such triggering event) entitling them to purchase, for
a period of 45 calendar days or less from the declaration date for such distribution, shares of Common Stock at a price per share less than the average Closing Sale Price of Common Stock for the 10 consecutive Trading Days immediately
preceding, but excluding, the declaration date for such distribution; or 
 (B) makes a distribution to all or substantially
all holders of its Common Stock cash, other assets, securities or rights to purchase securities of the Issuer or the Company (other than any distribution issued under a stockholder rights plan that is (i) transferable with shares of Common
Stock, including upon conversion, and (ii) not exercisable until the occurrence of a triggering event; provided that such distribution will be deemed issued under this subclause (B) upon the separation of such distribution from the
Common Stock, or upon the occurrence of such triggering event), which distribution has a per share value, as reasonably determined by the Board of Directors or committee thereof, exceeding 10% of the Closing Sale Price of the Common Stock on the
Trading Day immediately preceding the declaration date for such distribution, 

  
 57 








 
then, in either case, the Issuer shall notify all Holders, the Trustee and the Exchange Agent (if other than the Trustee) at least 45 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution by notice in writing, or if the Issuer does not have knowledge of such distribution at least 45 Scheduled Trading Days prior to the Ex-Dividend Date for such
distribution, within one Business Day of the date upon which the Issuer receives notice, or otherwise becomes aware, of such distribution. Once the Issuer has given such notice, a Holder may surrender all or any portion of its Notes for exchange any
time until the earlier of (1) the Close of Business on the Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution and (2) the Issuer’s announcement that such
issuance or distribution will not take place. 
 (iv) If a transaction or event that constitutes a Fundamental Change or a
Make-Whole Fundamental Change occurs prior to the Close of Business on the Business Day immediately preceding May 15, 2019, regardless of whether a Holder has the right to require the Issuer to repurchase the Notes pursuant to
Section 3.02, or if the Company is a party to a consolidation, merger, binding share exchange, or transfer or lease of all or substantially all of its assets, in each case, pursuant to which the Common Stock would be converted into cash,
securities or other assets (other than any merger or binding share exchange, in each case, solely for the purpose of changing the Company’s jurisdiction of organization that (x) does not constitute a Fundamental Change or a Make-Whole
Fundamental Change and (y) results in a reclassification, conversion or exchange of outstanding shares of Common Stock solely into shares of common stock of the surviving entity), all or any portion of a Holder’s Notes may be surrendered
for exchange at any time from or after the date that is 45 Scheduled Trading Days prior to the anticipated effective date of the transaction (or, if later, the Business Day after the Issuer gives notice of such transaction) until
35 Trading Days after the actual effective date of such transaction or, if such transaction also constitutes a Fundamental Change, until the related Fundamental Change Repurchase Date. The Issuer shall notify Holders, the Trustee and the
Exchange Agent (if other than the Trustee) in writing (i) as promptly as practicable following the date the Issuer publicly announces such transaction but in no event less than 45 Scheduled Trading Days prior to the anticipated effective
date of such transaction or (ii) if the Issuer does not have knowledge of such transaction at least 45 Scheduled Trading Days prior to the anticipated effective date of such transaction, within one Business Day of the date upon which the
Company or the Issuer publicly announces such transaction, but in no event later than the actual effective date of such transaction. 

(v) If the Company calls any or all of the Notes for redemption pursuant to Article 15 prior to the Close of Business on the
Business Day immediately preceding May 15, 2019, then a Holder may surrender all or any portion of its Notes for exchange at any time prior to the Close of Business on the Scheduled Trading Day prior to the Redemption Date, even if the Notes
are not otherwise exchangeable at such time. After that time, the right to convert such Notes as a result of such redemption shall expire, unless the Issuer defaults in the payment of the Redemption Price, in which case a Holder of Notes may convert
its Notes until the Redemption Price has been paid or duly provided for. 

  
 58 








 Section 13.02. Exchange Procedures; Settlement Upon Exchange. (a) In order to
exercise the exchange right with respect to any Notes in certificated form, a Holder must: 
 (i) complete and manually sign
a notice of exchange in the form entitled “Form of Exchange Notice” attached to the reverse of such certificated Note (or a facsimile thereof) (an “Exchange Notice”); 

(ii) deliver such Exchange Notice and the certificated Notes to be exchanged to the Exchange Agent at the office of the
Exchange Agent; 
 (iii) to the extent any shares of Common Stock issuable upon exchange are to be issued in a name other
than the Holder’s, furnish appropriate endorsements and transfer documents as may be required by the Exchange Agent; 

(iv) if required pursuant to this Section 13.02(a), pay funds equal to Interest payable on the next Interest Payment Date
to which such Holder is not entitled; and 
 (v) if required pursuant to Section 13.02(g), pay all transfer or similar
taxes, if any. 
 In order to exercise the exchange right with respect to any interest in a Global Note, a Holder must: 

(i) submit an Exchange Notice through the facilities of the Depositary and the Exchange Notice must comply with all applicable
Depositary procedures; 
 (ii) if required pursuant to this Section 13.02(a), pay funds equal to Interest payable on the
next Interest Payment Date to which such Holder is not entitled; and 
 (iii) if required pursuant to Section 13.02(g),
pay all transfer or similar taxes, if any. 
 The date on which the Holder satisfies the foregoing requirements is the “Exchange
Date.” The Notes shall be deemed to have been exchanged immediately prior to the Close of Business on the Exchange Date; provided, however, that the Person in whose name any shares of the Common Stock shall be issuable upon such
exchange shall become the holder of record of such shares as of the Close of Business on the Exchange Date, in the case of Physical Settlement, or the last Trading Day of the relevant Observation Period, in the case of Combination Settlement. 

Whether the Notes to be exchanged are held in book-entry or certificated form, the Exchange Notice will require the Holder to certify that it
is a qualified institutional buyer within the meaning of Rule 144A under the Securities Act. 
 If a Holder exchanges any Notes after
the Close of Business on the Record Date for an Interest payment but prior to the corresponding Interest Payment Date, the record Holder on such Record Date (if other than such Holder) shall receive on the corresponding Interest Payment Date the
full amount of Interest accrued and unpaid on such Notes, notwithstanding such

Holder’s exchange of those Notes prior to the Interest Payment Date. However, except as provided in the next sentence, at the time such Holder surrenders its Notes for exchange after the
Close of Business on a Record Date but prior to the Open of Business on the corresponding Interest Payment Date, such Holder must pay the Issuer an amount equal to the Interest that has accrued and shall be paid on the Notes being exchanged on the
corresponding Interest Payment Date. However, such Holder is not required to make such payment: 
 (i) if such Holder
exchanges its Notes following the Close of Business on the Record Date immediately preceding the Maturity Date; 
 (ii) if
the Issuer has specified a Redemption Date that is after a Record Date and on or prior to the date the corresponding Interest is paid; 

(iii) if such Holder exchanges its Notes in connection with a Fundamental Change and the Issuer has specified a Fundamental
Change Repurchase Date that is after a Record Date and on or prior to the date the corresponding Interest is paid; or 
 (iv)
to the extent of any overdue Interest, if overdue Interest exists at the time of exchange with respect to such Holder’s Notes. 
 For
the avoidance of doubt, all Record Holders of Notes on the Record Date immediately preceding the Maturity Date, any Redemption Date and any Fundamental Change Repurchase Date described in (i), (ii) and (iii) above will receive the
full Interest payment due on the Maturity Date or other applicable Interest Payment Date regardless of whether their Notes have been exchanged following such Record Date. 

If a Holder has already delivered a Fundamental Change Repurchase Notice pursuant to Section 3.02 with respect to a Note, such Holder may
not surrender that Note for exchange until such Holder has validly withdrawn the Fundamental Change Repurchase Notice in accordance with Section 3.04, except as to a portion of such Note that is not subject to such Fundamental Change Repurchase
Notice. 
 Upon surrender of a Note for exchange by a Holder, such Holder shall deliver to the Issuer cash equal to the amount that the
Issuer is required to deduct and withhold under applicable law in connection with such exchange; provided, however, that if the Holder does not deliver such cash, the Issuer may deduct and withhold from the consideration otherwise deliverable to
such Holder the amount required to be deducted and withheld under applicable law. 
 Upon the exchange of an interest in a Global Note, the
Trustee (or other Exchange Agent appointed by the Issuer), or the Custodian at the direction of the Trustee (or other Exchange Agent appointed by the Issuer), shall make a notation on such Global Note as to the reduction in the principal amount
represented thereby. The Issuer shall notify the Trustee in writing of any exchanges of Notes effected through any Exchange Agent other than the Trustee. 

(b) Subject to this Section 13.02 and Section 13.04, upon exchange of any Note, the Issuer may, at its election, pay or deliver, as
the case may be, to the exchanging Holder, in respect of each $1,000 principal amount of Notes being exchanged solely cash (“Cash 

  
 60 








 
Settlement”), solely shares of Common Stock (other than cash in lieu of any fractional shares) (“Physical Settlement”) or a combination of cash and shares of Common
Stock (“Combination Settlement”), as set forth in this Section 13.02(b). 
 All exchanges occurring on or after
May 15, 2019 and all exchanges for which the relevant Exchange Date occurs after the Issuer’s issuance of a Redemption Notice with respect to the Notes and prior to the related Redemption Date shall be settled using the same Settlement
Method. Prior to May 15, 2019 and with respect to any exchanges for which the relevant Exchange Date occurs after the Issuer’s issuance of a Redemption Notice but prior to the related Redemption Date, the Issuer shall use the same
Settlement Method for all exchanges occurring on the same Exchange Date, but the Issuer shall not have any obligation to use the same Settlement Method with respect to exchanges that occur on different Exchange Dates. If the Issuer elects a
Settlement Method, the Issuer shall notify Holders so exchanging, the Trustee and the Exchange Agent (if other than the Trustee) of such Settlement Method, no later than the Close of Business on the second Scheduled Trading Day immediately following
the related Exchange Date (or, in the case of any exchanges for which the relevant Exchange Date occurs (i) subject to the immediately following clause (ii), on or after the date of issuance of a Redemption Notice, in such Redemption Notice and
(ii) on or after May 15, 2019, no later than the Close of Business on the 45th Scheduled Trading Day immediately prior to the Maturity Date). If the Issuer does not timely elect a Settlement Method, the Issuer shall no longer have the
right to elect Cash Settlement or Physical Settlement, and the Issuer shall be deemed to have elected Combination Settlement in respect of its Exchange Obligation, and the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed
to be $1,000. If the Issuer elects Combination Settlement but does not timely notify exchanging Holders of the Specified Dollar Amount per $1,000 principal amount of Notes, such Specified Dollar Amount will be deemed to be $1,000. 

The cash, shares of Common Stock or combination of cash and shares of Common Stock in respect of any exchange of Notes (the
“Settlement Amount”) shall be computed as follows: 
 (i) if the Issuer elects to satisfy its Exchange
Obligation in respect of such exchange by Physical Settlement, the Issuer shall deliver to exchanging Holders in respect of each $1,000 principal amount of Notes being exchanged a number of shares of Common Stock equal to the Exchange Rate in effect
on the Exchange Date (and cash in lieu of any fractional share as described in Section 13.02(i)); 
 (ii) if the Issuer
elects to satisfy its Exchange Obligation in respect of such exchange by Cash Settlement, the Issuer shall pay to exchanging Holders in respect of each $1,000 principal amount of Notes being exchanged cash in an amount equal to the sum of the Daily
Exchange Values for each of the 40 consecutive Trading Days in the relevant Observation Period; and 
 (iii) if the Issuer
elects (or is deemed to have elected) to satisfy its Exchange Obligation in respect of such exchange by Combination Settlement, the Issuer shall pay or deliver, as the case may be, to exchanging Holders in respect of each $1,000 principal amount of
Notes being exchanged, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 40 consecutive Trading Days in the relevant Observation Period (and cash in lieu of any fractional share as described in
Section 13.02(i)). 

  
 61 








 (c) Except as set forth in Section 13.04, if Cash Settlement or Combination Settlement is
applicable, the Issuer shall pay and/or deliver the consideration due upon exchange on the third Business Day immediately following the final Trading Day of the related Observation Period. If Physical Settlement is applicable, the Issuer shall
deliver the consideration due upon exchange on the third Business Day immediately following the related Exchange Date; provided that, with respect to any Exchange Date with respect to which Physical Settlement applies occurring after
May 15, 2019, settlement will occur on the Maturity Date. 
 (d) If more than one Note shall be surrendered for exchange at one time by
the same Holder, the Exchange Obligation with respect to such Notes, if any, that shall be payable upon exchange shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted
thereby) so surrendered. 
 (e) In case any certificated Note shall be surrendered for partial exchange, the Issuer shall execute and the
Trustee shall authenticate and deliver to or upon the written order of the Holder of the certificated Note so surrendered, without charge to such Holder, a new certificated Note or Notes in authorized denominations in an aggregate principal amount
equal to the unexchanged portion of the surrendered certificated Note. 
 (f) Upon the exchange of an interest in a Global Note, the Trustee
and the Depositary shall reduce the principal amount of such Global Note in their records. 
 (g) The issue of stock certificates on
exchanges of Notes shall be made without charge to the exchanging Holder of Notes for any taxes or duties in respect of the issue thereof. The Issuer shall not, however, be required to pay any such tax or duty which may be payable in respect of any
transfer involved in the issue and delivery of stock in any name other than that of the Holder of any Notes exchanged, and the Issuer shall not be required to issue or deliver any such stock certificate unless and until the Person or Persons
requesting the issue thereof shall have paid to the Issuer the amount of such tax or duty or shall have established to the satisfaction of the Issuer that such tax has been paid. 

(h) Except as provided in Section 13.02(a), upon exchange, Holders shall not receive any separate cash payment of accrued and unpaid
Interest on the Notes. Accrued and unpaid Interest to the Exchange Date shall be deemed to be paid in full with the payment or delivery, as the case may be, of the cash, Common Stock or a combination thereof, upon exchange, rather than cancelled,
extinguished or forfeited. With respect to any exchange with Combination Settlement, accrued and unpaid Interest will be deemed to be paid first out of the cash paid upon such exchange. 

(i) The Issuer shall not deliver fractional shares of Common Stock upon exchange of the Notes. If any fractional shares of Common Stock would
be issuable upon the exchange of any Note or Notes, the Issuer shall instead pay cash in lieu of fractional shares based on the Closing Sale Price of the Common Stock on the relevant Exchange Date, in the case of Physical Settlement, or on the final
Trading Day of the relevant Observation Period, in the case of Combination Settlement. 

  
 62 








 (j) Except as may be set forth in Section 13.03, the Issuer shall not make any payment or
other adjustment for dividends on any Common Stock issued upon exchange of the Notes. 
 (k) The Issuer shall inform the Trustee upon its
request if the Notes have become exchangeable under Section 13.01(b). 
 Section 13.03. Adjustment of Exchange Rate. The
Exchange Rate shall be adjusted from time to time as follows: 
 (a) If the Company issues Common Stock as a dividend or distribution on
Common Stock, or if the Company effects a share split or share combination, the Exchange Rate will be adjusted based on the following formula: 
  





 
 where 
  

			
	ER0 =	  	the Exchange Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such dividend or distribution, or the effective date of such share split or share
combination;
		
	ER1 =	  	the new Exchange Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution, or the effective date of such share split or share
combination;
		
	OS0 =	  	the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date, or effective date of such share split or share combination; and
		
	OS1 =	  	the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date, or effective date of such share split or share combination but after giving
effect to such dividend, distribution, share split or share combination.


 If any dividend or distribution described in this paragraph (a) is declared but not so paid or
made, the new Exchange Rate shall be readjusted to the Exchange Rate that would then be in effect if such dividend or distribution had not been declared or such subdivision or combination had not been announced. 

(b) If the Company distributes to all, or substantially all, holders of Common Stock any rights, warrants or options entitling them for a
period of not more than 45 days after the announcement date of such issuance to subscribe for or purchase Common Stock at an exercise 

  
 63 








 
price per share of Common Stock less than the average of the Closing Sale Prices of Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the
time of announcement of such issuance, the Exchange Rate will be adjusted based on the following formula: 
  
 



 
 where 
  

			
	ER0 =	  	the Exchange Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
		
	ER1 =	  	the new Exchange Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such distribution;
		
	OS0 =	  	the number of shares of Common Stock outstanding immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
		
	X =	  	the total number of shares of Common Stock issuable pursuant to such rights, warrants or options; and
		
	Y =	  	the number of shares of Common Stock equal to the quotient of (a) the aggregate price payable to exercise such rights, warrants or options and (b) the average of the Closing Sale Prices of the Common Stock for the
10 consecutive Trading Days ending on the Trading Day immediately preceding the date of announcement for the issuance of such rights, warrants or options.


 Any increase made under this Section 13.03(b) will be made successively whenever any such rights,
options or warrants are issued and shall become effective immediately after the Open of Business on the Ex-Dvidend Date for such issuance. To the extent that shares of Common Stock are not delivered after the expiration of such rights, options or
warrants, the Exchange Rate shall be readjusted to the Exchange Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of
Common Stock actually delivered. If such rights, options or warrants are not so issued, the Exchange Rate shall be readjusted to the Exchange Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred. 

For purposes of this Section 13.03(b) and for the purpose of Section 13.01(b)(iii)(A), in determining whether any rights, warrants
or options entitle the holders to subscribe for or purchase shares of Common Stock at less than such average of the Closing Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day
immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the the Issuer or the Company for such
rights, options 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 or a committee thereof. 

  
 64 








 (c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness or
other assets or property of the Company to all, or substantially all, holders of Common Stock, excluding: 
 (A) dividends,
distributions, rights, warrants or options referred to in clause (a) or (b) of this Section 13.03; 
 (B)
dividends or distributions paid exclusively in cash; 
 (C) Spin-Offs described below in this clause (c); and 

(D) Any distributions of Reference Property pursuant to a transaction described below under Section 13.05, then the
Exchange Rate will be adjusted based on the following formula: 
  
 



 
 where 
  

			
	ER0 =	  	the Exchange Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
		
	ER1 =	  	the new Exchange Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such distribution;
		
	SP0 =	  	the average of the Closing Sale Prices of Common Stock over the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend Date for such
distribution; and
		
	FMV =	  	the fair market value (as determined in good faith by the Board of Directors, or a committee thereof) of the shares of Capital Stock, evidences of indebtedness, assets or property distributed with respect to each outstanding share
of Common Stock on the Ex-Dividend Date for such distribution.


 Any increase made under the portion of this Section 11.03(c) above will become effective
immediately after the Open of Business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Exchange Rate shall be decreased to be the Exchange Rate that would then be in effect if such distribution had not
been declared. Notwithstanding the foregoing, if “FMV” with respect to any distribution of shares of Capital Stock, evidences of indebtedness or other assets or property of the Company is equal to or greater than “SP0” with respect to such distribution, then in lieu of the foregoing adjustment, adequate provision shall be made so that each holder of Notes shall have the right to receive on the date such
shares of Capital Stock, evidences of indebtedness or other assets or property of the Company are distributed to holders of Common Stock, for each Note, the amount of shares of Capital Stock, evidences of indebtedness or other assets or property of
the Company such holder of Notes would have received had such holder of Notes owned a number of shares of Common Stock 

  
 65 








 
equal to a fraction (x) the numerator of which is the product of the Exchange Rate in effect on the Ex-Dividend Date for such distribution, and the
aggregate principal amount of Notes held by such Holder and (y) the denominator of which is $1,000. 
 With respect to an adjustment to
the Exchange Rate made pursuant to this clause (c), where there has been a payment of a dividend or other distribution of Common Stock or shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary
or other business unit of the Company that are or, when issued, will be, listed or admitted for trading on a U.S. national or regional securities exchange (a “Spin-Off”), the Exchange Rate will be adjusted based on the following
formula: 
  
 



 
 where 
  

			
	ER0 =	  	the Exchange Rate in effect immediately prior to the end of the Valuation Period (as defined below);
		
	ER1 =	  	the Exchange Rate in effect immediately after the end of the Valuation Period;
		
	FMV0 =	  	the average of the Closing Sale Prices of the Capital Stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock (determined by reference to the definition of Closing Sale Price
as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation
Period”); and
		
	MP0 =	  	the average of the Closing Sale Prices of the Common Stock over the Valuation Period.


 An adjustment to the Exchange Rate made pursuant to the immediately preceding paragraph will become
effective immediately after the end of the Valuation Period; provided that in respect of any exchange within the Valuation Period, references within this clause (c) to 10 Trading Days shall be deemed replaced with such lesser number
of Trading Days as have elapsed between the effective date of such Spin-Off and the Exchange Date in determining the applicable Exchange Rate. 

If any dividend or distribution described in this clause (c) is declared but not paid or made, the new Exchange Rate shall be readjusted
to be the Exchange Rate that would then be in effect if such dividend or distribution had not been declared. 
 For purposes of this
Section 13.03(c) (and subject in all respect to Section 13.03(f)), rights, options or warrants distributed by the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital
Stock, including Common Stock (either initially or under certain circumstances), which rights, options or 

  
 66 








 
warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of the Common Stock; (ii) are not
exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 13.03(c) (and no adjustment to the Exchange Rate under this
Section 13.03(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Exchange Rate
shall be made under this Section 13.03(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such
rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any
of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto
that was counted for purposes of calculating a distribution amount for which an adjustment to the Exchange Rate under this Section 13.03(c) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed
or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Exchange Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Exchange Rate shall then again be
readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders of Common Stock with
respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or
warrants that shall have expired or been terminated without exercise by any holders thereof, the Exchange Rate shall be readjusted as if such rights, options and warrants had not been issued. 

For purposes of 13.03(a), Section 13.03(b) and this Section 14.03(c), if any dividend or distribution to which this
Section 13.03(c) is applicable also includes one or both of: 
 (A) a dividend or distribution of shares of Common Stock to
which Section 13.03(a) is applicable (the “Clause A Distribution”); or 
 (B) a dividend or
distribution of rights, options or warrants to which Section 13.03(b) is applicable (the “Clause B Distribution”), 

then (1) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be
deemed to be a dividend or distribution to which this Section 13.03(c) is applicable (the “Clause C Distribution”) and any Exchange Rate adjustment required by this Section 13.03(c) with respect to such Clause C
Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Exchange Rate adjustment required by Section 13.03(a) and
Section 13.03(b) with respect thereto shall then be made, except that, if determined by the Company, (I) the “Ex-Dividend Date” of the Clause A Distribution and the 


  
 67 








 
Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included
in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the Open of Business on such Ex-Dividend Date, or effective date” within
the meaning of Section 13.03(a) or “outstanding immediately prior to the Open of Business on the Ex-Dividend Date” within the meaning of Section 13.03(b). 

(d) If the Company makes any cash dividend or distribution to all, or substantially all, holders of outstanding Common Stock, other
than cash dividends in any fiscal quarter that do not exceed in aggregate $0.085 per share (such threshold, subject to adjustment as provided below, the “Dividend Threshold”) the Exchange Rate will be adjusted based on the following
formula: 
  
 



 
 where 
  

			
	ER0 =	  	the Exchange Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such dividend or distribution;
		
	ER1 =	  	the new Exchange Rate immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution;
		
	SP0 =	  	the Closing Sale Price of Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution;
		
	T =	  	the Dividend Threshold; and
		
	C =	  	the aggregate amount in cash per share that the Company distributes to holders of Common Stock in a fiscal quarter;


 The Dividend Threshold is subject to adjustment in a manner inversely proportional to adjustments to the
Exchange Rate made pursuant to the provisions described in this Section 11.03; provided that no adjustment will be made to the Dividend Threshold for any adjustment to the Exchange Rate under this clause (d). 

If any dividend or distribution described in this clause (d) is declared but not so paid or made, the new Exchange Rate shall be
readjusted to the Exchange Rate that would then be in effect if such dividend or distribution had not been declared, effective as of the date the Board of Directors or committee thereof determines not to make or pay such dividend or distribution.
Notwithstanding the foregoing, if “C” with respect to any such cash dividend or distribution is equal to or greater than “SP0” with respect to any such cash dividend or
distribution, then in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder of Notes shall have the right to receive on the date such cash is distributed to holders of Common Stock, for each Note, the amount of cash
such Holder would have received had such Holder owned a number of shares of Common Stock equal to the Exchange Rate in effect on the Ex-Dividend Date for such dividend or distribution. 

  
 68 








 If any dividend or distribution described in this paragraph (d) is declared but not so paid
or made, the new Exchange Rate shall be readjusted to the Exchange Rate that would then be in effect if such dividend or distribution had not been declared. 

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer that is subject to the
then applicable tender offer rules under the Exchange Act for Common Stock to the extent that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the Closing Sale Price of a share of Common Stock
on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender offer or exchange offer (the “Expiration Time”), the Exchange Rate will be adjusted based on the following
formula: 
  
 



 
 where 
  

			
	ER0 =	  	the Exchange Rate in effect immediately prior to the Close of Business on the date such tender or exchange offer expires;
		
	ER1 =	  	the Exchange Rate in effect immediately following the Close of Business on the date such tender offer or exchange offer expires;
		
	AC =	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors or committee thereof) paid or payable for the Common Stock purchased in such tender or exchange offer;
		
	OS0 =	  	the number of shares of Common Stock outstanding immediately prior to the Expiration Time on the date such tender offer or exchange offer expires (prior to giving effect to the purchase or exchange of all shares accepted for
purchase or exchange in such tender or exchange offer);
		
	OS1 =	  	the number of shares of Common Stock outstanding immediately after the Expiration Time on the date such tender or exchange offer expires (after giving effect to the purchase or exchange of all shares accepted for purchase or
exchange in such tender offer or exchange offer); and
		
	SP1 =	  	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on the Trading Day next succeeding the date such tender offer or exchange offer expires.


 The adjustment to the exchange rate under the preceding paragraph shall occur on the 10th Trading Day
from, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that in respect of any exchange within 10 Trading Days immediately following, and including, the expiration date of any tender or
exchange offer, references with respect to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the expiration date of such tender or exchange offer and the Exchange Date in determining the
applicable Exchange Rate. 

  
 69 








 If the Company or one of its Subsidiaries is obligated to purchase Common Stock pursuant to any
such tender offer or exchange offer but is permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the new Exchange Rate shall be readjusted to be the Exchange Rate that would be in effect if
such tender offer or exchange offer had not been made. 
 (f) If the Company has in effect a rights plan while any Notes remain outstanding,
Holders of Notes will receive, upon an exchange of Notes, in addition to Common Stock, if any, rights under the Company’s stockholder rights agreement unless, prior to exchange, the rights have expired, terminated or been redeemed or unless the
rights have separated from the Common Stock. If the rights provided for in the rights plan adopted by the Company have separated from the Common Stock and have not expired, terminated or been redeemed, in each case, in accordance with the provisions
of the applicable stockholder rights agreement so that Holders of Notes would not be entitled to receive any rights in respect of any shares of Common Stock delivered upon an exchange of Notes, the Exchange Rate will be adjusted at the time of
separation as if the Company had distributed, to all holders of Common Stock, Capital Stock, evidences of indebtedness or other assets or property pursuant to clause (c) above, subject to readjustment upon the subsequent expiration, termination
or redemption of the rights. 
 (g) If, in the case of any exchange of a Note, on any Trading Day during the Observation Period for such
Note, shares of Common Stock are deliverable as part of the Daily Settlement Amount for such Trading Day, and 
 (i) the
Ex-Dividend Date for any issuance, dividend or distribution, the effective date for any share split or combination or the expiration date for any tender or exchange offer by the Company that, in each case, would require an adjustment to the Exchange
Rate under clauses (a) through (e) above occurs prior to the Issuer’s delivery of such shares of Common Stock to the exchanging Holder; 

(ii) the applicable Exchange Rate for such Trading Day will not reflect such adjustment; and 

(iii) the shares of Common Stock that the Issuer will deliver to the exchanging Holder with respect of such Trading Day are not
entitled to participate in the relevant event (because they were not held on the related Ex-Dividend Date, effective date, expiration date or otherwise), 

then the Issuer will adjust the number of shares of Common Stock that it delivers to such Holder as part of the Daily Settlement Amount for such Trading Day
in a manner that appropriately reflects the relevant distribution, transaction or event. 
 Notwithstanding the foregoing, if an Exchange
Rate adjustment becomes effective on any Ex-Dividend Date as described in Section 13.03(a) through 13.03(e) above, and a Holder of Notes that has exchanged its Notes on or after such Ex-Dividend Date and
on or prior to the 

  
 70 








 
related record date would be treated as the record holder of Common Stock as of the related Exchange Date as described under Section 13.02, based on an adjusted Exchange Rate for such Ex-Dividend Date, then, notwithstanding the foregoing Exchange Rate adjustment provisions of Section 13.03(a) through (e), the Exchange Rate adjustment relating to such
Ex-Dividend Date will not be made for such exchanging Holder. Instead, such Holder will be treated as if such Holder were, as of such record date, the record owner of the Common Stock issuable upon such
exchange on an unadjusted basis and will participate in the related dividend, distribution or other event giving rise to such adjustment. 

(h) The Issuer shall not make any adjustment to the Exchange Rate if Holders of the Notes are permitted to participate in the transactions
described in this Section 13.03 on a basis equivalent to that which would apply if the Notes were exchanged entirely for Common Stock at the then-applicable Exchange Rate. If, however, the application of the foregoing formulas would result in a
decrease in the Exchange Rate, no adjustment to the Exchange Rate shall be made (other than as a result of an adjustment pursuant to Section 13.03(a)). 

Notwithstanding anything to the contrary contained herein, the applicable Exchange Rate shall not be adjusted for: 

(i) the issuance of any Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or
interest payable on securities of the Issuer or those of the Company and the investment of additional optional amounts in the Common Stock under any plan; 

(ii) the issuance of any Common Stock or options or rights to purchase those shares pursuant to any present or future employee,
director, trustee or consultant benefit plan, employee agreement or arrangement or program of the Company or any of its subsidiaries; 

(iii) the issuance of any Common Stock pursuant to any option, warrant, right, or exercisable, exchangeable or convertible
security outstanding as of the date the Notes were first issued; 
 (iv) a change in the par value of the Common Stock; 

(v) accumulated and unpaid dividends or distributions; 

(vi) the issuance of Units by the Issuer and the issuance of the Common Stock or the payment of cash upon redemption thereof;
and 
 (vii) the repurchase of any shares of Common Srock pursuant to an open-marked share repurchase program or other
buy-back transaction that is not a tender offer or exchange offer of the kind described under Section 11.03(e). 
 Adjustments to the
applicable Exchange Rate shall be calculated to the nearest 1/10,000th of a share. The Issuer shall not adjust the Exchange Rate pursuant to the provisions of this Section 11.03 unless the adjustment would result in a change of at least 1% of
the then effective Exchange Rate. However, the Issuer shall carry forward any adjustment that it would otherwise

have to make and take that adjustment into account in any subsequent adjustment. Notwithstanding the foregoing, all such carried-forward adjustments shall be made with respect to the Notes
(i) in connection with any subsequent adjustment to the Exchange Rate of at least 1% and (ii) on each Trading Day of any Observation Period related to the exchange of the Notes. 

Notwithstanding anything to the contrary herein, certain listing standards of The New York Stock Exchange may limit the amount by which the
Issuer may increase the Exchange Rate pursuant to the events described in clauses (a) through (e) in this Section 13.03 and as described in Section 13.04. These standards generally require the Company to obtain the approval of
its stockholders before entering into certain transactions that potentially result in the issuance of 20% or more of Common Stock outstanding at the time the Notes are issued unless the Company obtains stockholder approval of issuances in excess of
such limitations. Accordingly, in the event of an increase in the Exchange Rate above that which would result in the Notes, in the aggregate, becoming exchangeable into shares in excess of such limitations, the Company will, at its option, either
obtain stockholder approval of such issuances or pay cash in lieu of delivering any shares otherwise deliverable upon exchange in excess of such limitations based on the volume-weighted average price of Common stock for each Trading Day of the
relevant Observation Period in respect of which, in lieu of delivering common shares, the Issuer delivers cash pursuant to this paragraph, in the case of Combination Settlement, or based on the Closing Sale Price of Common Stock on an Exchange Date
with respect to Physical Settlement. 
 The Issuer from time to time may increase the Exchange Rate by any amount for a period of at least
20 Business Days if the Board of Directors or a committee thereof determines that such increase would be in the Company’s best interest. In addition, the Issuer may also (but is not required to) increase the Exchange Rate to avoid or
diminish income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar event. 

Except as set forth above in this Article 13, the Exchange Rate shall not be adjusted. 

Whenever the Exchange Rate is adjusted as herein provided, the Company or the Issuer shall as promptly as reasonably practicable file with the
Trustee and any Exchange Agent other than the Trustee an Officer’s’ Certificate setting forth the Exchange Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Promptly after delivery of
such certificate, the Company or the Issuer shall prepare a notice of such adjustment of the Exchange Rate setting forth the adjusted Exchange Rate and the date on which each adjustment becomes effective and shall mail such notice of such adjustment
of the Exchange Rate to the Holders of the Notes within 20 Business Days of the Effective Date of such adjustment. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 

For purposes of this Section 13.03, “effective date” means the the first date on which the shares of Common Stock trade on the
applicable exchange or in the applicable market, regular way, reflecting the relevant share split or share combination, as applicable. 

(i) Whenever any provision of this Indenture requires the Issuer to calculate the Closing Sale Prices, the volume-weighted average price, the
Daily Exchange Values or the Daily Settlement Amounts over, or based on, a span of multiple calendar days (including an 

  
 72 








 
Observation Period, Valuation Period or Averaging Period), the Issuer shall make appropriate adjustments to each (to the extent no corresponding adjustment is otherwise made pursuant to the
provisions of this Section 13.03) to account for any adjustment to the Exchange Rate that becomes effective, or any event requiring an adjustment to the Exchange Rate where the Ex-Dividend Date of the
event occurs, at any time during the period when the Closing Sale Prices, the volume-weighted average prices, the Daily Exchange Values or the Daily Settlement Amounts are to be calculated. 

Section 13.04. Exchange Rate Adjustment After Make-Whole Fundamental Change. (a) Subject to the provisions hereof, if a Noteholder
elects to exchange its Notes in connection with a Make-Whole Fundamental Change, the Issuer will increase the applicable Exchange Rate for the Notes so surrendered for exchange by a number of additional shares of Common Stock (the
“Additional Shares”) as specified below; provided that the Additional Shares will only be payable as set forth below. An exchange of Notes will be deemed for these purposes to be “in connection with” such a
Make-Whole Fundamental Change if the Exchange Date occurs during the period from the effective date of such Make-Whole Fundamental Change until the corresponding Fundamental Change Repurchase Date or, if such Make-Whole Fundamental Change is not
also a Fundamental Change, the 35th Business Day immediately following the effective date for such Make-Whole Fundament Change. 
 Upon
surrender of Notes for exchange in connection with a Make-Whole Fundamental Change, the Issuer shall, at its option, satisfy its Exchange Obligation by Physical Settlement, Cash Settlement or Combination Settlement, as described under
Section 13.02(b). However, if the consideration received by holders of the Common Stock in any Make-Whole Fundamental Change described in clause (2) of the definition of Fundamental Change is composed entirely of cash, for any exchange of
Notes following the Effective Date of such Make-Whole Fundamental Change, the Settlement Amount will be calculated based solely on the Stock Price for the transaction and will be deemed to be an amount of cash per $1,000 principal amount of
exchanged Notes equal to the Exchange Rate (including any adjustment as described in this Section 13.04), multiplied by such Stock Price. In such event, the Issuer shall satisfy its Exchange Obligation by paying cash to exchanging Holders on
the third Business Day immediately following the Exchange Date. 
 (b) The number of Additional Shares will be determined by reference to
the table in paragraph (e) below and is based on the date on which the Make-Whole Fundamental Change transaction becomes effective (the “Effective Date”) and the price (the “Stock Price”) paid per share of
Common Stock in such transaction. If the holders of Common Stock receive only cash in the relevant Make-Whole Fundamental Change transaction, the Stock Price will equal the cash amount paid per share of Common Stock. In all other cases, the Stock
Price will equal the average of the Closing Sale Prices of the Common Stock on the 10 consecutive Trading Days up to but excluding the Effective Date. 

(c) The Stock Prices set forth in the first row of the table below shall be adjusted as of any date on which the Exchange Rate of the Notes is
adjusted. The adjusted Stock Prices will equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, (i) the numerator of which is the Exchange Rate immediately prior to the adjustment giving rise to the
Stock Price adjustment and (ii) the denominator of which is the Exchange Rate as so adjusted. 

  
 73 








 (d) The number of Additional Shares will be adjusted in the same manner and for the same events
as the Exchange Rate is adjusted pursuant to Section 13.03. 
 (e) The following table sets forth the number of Additional Shares by
which the Exchange Rate will be increased per $1,000 principal amount of Notes for each Stock Price and Effective Date set forth below:

 (f) If the exact Stock Price and Effective Date are not set forth on the table above, then: 

(i) if the Stock Price is between two Stock Prices in the table or the Effective Date is between two dates in the table, the
Additional Shares will be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the two dates, as applicable, based on a 365-
or 366-day year, as applicable; 
 (ii) if the Stock Price is in excess of $70.00 per share of Common Stock (the
“Adjustment Cap”) (subject to adjustment) no Additional Shares will be added to the applicable Exchange Rate; and 

(iii) if the Stock Price is less than $15.88 per share of Common Stock (the “Adjustment Floor”) (subject to
adjustment) no Additional Shares will be added to the applicable Exchange Rate. 
 The Adjustment Cap and Adjustment Floor shall be adjusted
as of any date on which the Exchange Rate of the Notes is adjusted pursuant to Section 13.03. The adjusted Adjustment Cap or Adjustment Floor, as the case may be, shall equal the Adjustment Cap or Adjustment Floor, as the case may be,
applicable immediately prior to such adjustment, multiplied by a fraction, (i) the numerator of which is the Exchange Rate immediately prior to the adjustment giving rise to the adjustment and (ii) the denominator of which is the Exchange
Rate as so adjusted. 
 (g) Notwithstanding anything in this Section 13.04 to the contrary, in no event will the total number of shares
of Common Stock issuable upon exchange of the Notes exceed 62.9722 per $1,000 principal amount of Notes, subject to adjustment in the same manner as the Exchange Rate pursuant to Section 13.03. 

  
 74 








 Section 13.05. Effect of Recapitalization, Reclassification, Consolidation, Merger or
Sale. (a) If any of the following events occur: 
 (i) any recapitalization, reclassification or change of shares of
Common Stock issuable upon exchange of the Notes (other than a change as a result of a subdivision or combination or change in par value); 

(ii) any consolidation, merger or combination involving the Company with another Person as a result of which holders of Common
Stock shall be entitled to receive cash, securities or other property or assets (including cash or any combination of the foregoing) with respect to or in exchange for such Common Stock; or 

(iii) any sale, lease or other transfer to a third party of all or substantially all of the consolidated assets of the Company
and its Subsidiaries to any other Person as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash or any combination of the foregoing) with respect to or in exchange for
such Common Stock, 
 (any such event, a “Merger Event”) then, at the effective time of the Merger Event, the Company or the
successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture) providing that the
Notes shall be exchangeable for the kind and amount of shares of stock, securities or other property or assets (including cash or any combination of the foregoing) receivable upon such recapitalization, reclassification, change, consolidation,
merger, combination, sale or conveyance (the “Reference Property”) by a holder of a number of shares of Common Stock issuable upon exchange for such Notes (assuming, for such purposes, a sufficient number of authorized shares of
Common Stock available to exchange all such Notes) immediately prior to such Merger Event. However, at and after the effective time of the Merger Event, (a) the Issuer shall continue to have the right to determine the form of consideration to
be paid or delivered, as the case may be, as set forth in Section 13.02 and (B)(1) any amount payable in cash upon exchange of the Notes as set forth in Section 13.02 will continue to be payable in cash, (2) any shares of Common Stock
that the Issuer would have been required to deliver upon exchange of the Notes as set forth in Section 13.02 will instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would
have received in such transaction and (3) VWAP will be calculated based on the value of the amount and kind of Reference Property that a holder of one share of Common Stock would have received in such transaction. If the Merger Event causes
Common Stock to be exchanged for the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), the Reference Property for which the Notes will be exchangeable shall be deemed to be
(x) the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such election or (y) if no holders of Common Stock affirmatively make such an election, the types and
amounts of consideration actually received by the holders of Common Stock.  

  
 75 








 In connection with any transaction described in this Section 13.05 the Issuer shall also
adjust the Dividend Threshold based on the ratio of the value of the shares of common stock, if any, comprising the Reference Property to the value of any non-stock consideration comprising the Reference Property. If the Reference Property is
composed solely of non-stock consideration, the Dividend Threshold will be zero. 
 Such supplemental indenture providing that the Notes
will be exchangeable into Reference Property will also provide for antidilution and other adjustments that are as nearly equivalent as possible to the adjustments described under this Article 13. If the Reference Property in respect of any such
transaction includes shares of stock, securities or other property or assets of a company other than the Company or the successor or purchasing corporation, as the case may be, in such transaction, such other company will also execute such
supplemental indenture, and such supplemental indenture will contain such additional provisions to protect the interests of the Holders, including the right of Holders to requirethe Issuer to repurchase their Notes upon a Fundamental Change as
described under Section 3.02, as the Board of Directors or committee thereof reasonably considers necessary by reason of the foregoing. 

The Issuer 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 maintained by the Note Registrar, 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 13.05 shall similarly apply to successive recapitalizations, reclassifications, changes, consolidations, mergers, combinations, sales and conveyances. 

(b) Neither the Company nor the Issuer shall become a party to any such transaction unless its terms are consistent with this
Section 13.05. 
 Section 13.06. Ownership Limit and Withholding. 

(a) Notwithstanding any other provision of the Notes or this Indenture, no Holder of Notes will be entitled to receive Common Stock following
exchange of such Notes to the extent that receipt of such Common Stock would cause such Holder to exceed the ownership limits contained in the Company’s Charter. If any delivery of shares of Common Stock owed to a Holder upon exchange of Notes
is not made, in whole or in part, as a result of the limitations described in this Section 13.06 (a), the Issuer’s obligation to make such delivery shall not be extinguished and the Issuer shall deliver such shares as promptly as
practicable after any such exchanging Holder gives notice to the Issuer that such delivery would not result in it being the beneficial or constructive owner of more than 9.8% (in value or in number of shares, whichever is more restrictive) of the
shares of Common Stock outstanding at such time. 
 (b) At the Maturity Date, upon earlier repurchase of the Notes or at any time a payment
is made with respect to the Notes, and as otherwise required by law, the Issuer may deduct and withhold from such amount otherwise deliverable to the Holder the amount required to be deducted and withheld under applicable law, and such amount shall
be deemed paid to such Holder for all purposes of this Indenture. 
 Section 13.07. Calculations in Respect of Notes. Except as
otherwise specifically stated herein or in the Notes, all calculations to be made in respect of the Notes shall be the obligation of the Issuer. These calculations include, but are not limited to, determinations of the Closing


  
 76 








 
Sale Price or the volume-weighted average price of the Common Stock, the Daily Settlement Amounts, the Daily Exchange Values, accrued Interest payable on the Notes, the Exchange Rate and the
Exchange Price. All calculations made by the Issuer or its agent as contemplated pursuant to the terms hereof and of the Notes shall be made in good faith and be final and binding on the Notes and the Holders of the Notes absent manifest error. The
Issuer shall provide a schedule of calculations to the Trustee, and the Trustee shall be entitled to rely upon the accuracy of the calculations by the Issuer without independent verification. The Trustee, at the expense of the Issuer, shall forward
calculations made by the Issuer to any Holder of Notes upon written request. None of the Trustee, the Note Registrar, the Paying Agent, the Exchange Agent and the Bid Solicitation Agent (if other than the Issuer) shall have any responsibility to
determine the Trading Price of the Notes or the Closing Sale Price or whether the conditions to exchange specified in Article 13 have been satisfied. 

Section 13.08. Designation to an Institution in Lieu of Exchange. When a Holder surrenders its Notes for exchange, the Issuer may,
at its election (an “Exchange Election”), direct the Exchange Agent to surrender, on or prior to the second Trading Day following the Exchange Date, such Notes to a financial institution designated by the Issuer in lieu of exchange.
In order to accept any Notes surrendered for exchange, the designated financial institution must agree to timely deliver, in exchange for such Notes, the shares of Common Stock, cash or combination thereof due upon exchange as described above under
Section 13.02. If the Issuer makes an Exchange Election, it will, by the Close of Business on the second Trading Day following the relevant Exchange Date, notify the Holder surrendering its Notes for exchange that it has made the Exchange
Election, and it will notify the designated financial institution of the Settlement Method it has elected with respect to such exchange and the relevant deadline for payment and/or delivery of shares of Common Stock, cash or a combination thereof
due upon exchange. 
 Any Notes exchanged by the designated institution will remain outstanding. If the designated institution agrees to
accept any Notes for exchange but does not timely pay or deliver the aggregate cash, shares of Common Stock or a combination of cash and shares Common Stock, as the case may be, due upon exchange or if such designated financial institution does not
accept the Notes for exchange, the Issuer will pay or deliver, as the case may be, cash, shares of Common Stock or a combination of cash and shares of Common Stock, as the case may be, to the exchanging Holder at the time and in the manner required
herein as if it had not made an Exchange Election. 
 The Issuer’s designation of an institution to which the Notes may be designated
does not require the institution to accept any Notes (unless the financial institution has separately made an agreement with the Issuer). The Issuer may, but will not be obligated to, enter into a separate agreement with any designated financial
institution that would compensate it for any such transaction. 
 ARTICLE 14 

MEETINGS OF HOLDERS OF NOTES 

Section 14.01. Purposes for Which Meetings May Be Called. A meeting of Holders of Notes may be called at any time and from
time to time pursuant to this Article 14 to make, give or take any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be made, given or taken by Holders of Notes. 

  
 77 








 Section 14.02. Call, Notice and Place of Meetings. (a) The Trustee may at any
time call a meeting of Holders of Notes for any purpose specified in Section 14.01, to be held at such time and at such place as the Trustee shall determine. Notice of every meeting of Holders of Notes, setting forth the time and the place of
such meeting and in general terms the action proposed to be taken at such meeting, shall be given, in the manner provided in Section 16.03, not less than 20 nor more than 180 days prior to the date fixed for the meeting. 

(b) In case at any time the Issuer, pursuant to a Board Resolution, the Company, or the Holders of at least 25% in principal amount of the
outstanding Notes shall have requested the Trustee to call a meeting of the Holders of Notes for any purpose specified in Section 14.01, by written request setting forth in reasonable detail the action proposed to be taken at the meeting, and
the Trustee shall not have made the first publication of the notice of such meeting within 20 days after receipt of such request or shall not thereafter proceed to cause the meeting to be held as provided herein, then the Issuer, the Company or
the Holders of Notes in the amount above specified, as the case may be, may determine the time and the place for such meeting and may call such meeting for such purposes by giving notice thereof as provided in subsection (a) of this
Section 14.02. 
 Section 14.03. Persons Entitled to Vote at Meetings. To be entitled to vote at any meeting of Holders of
Notes, a Person shall be (a) a Holder of one or more outstanding Notes, or (b) a Person appointed by an instrument in writing as proxy for a Holder or Holders of one or more outstanding Notes by such Holder or Holders. The only Persons who

Company and their respective counsel. 
 Section 14.04. Quorum; Action. The Persons entitled to vote a majority in principal
amount of the outstanding Notes shall constitute a quorum for a meeting of Holders of Notes; provided, however, that if any action is to be taken at such meeting with respect to a consent or waiver which this Indenture expressly provides may
be given by the Holders of not less than a specified percentage in principal amount of the outstanding Notes, the Persons entitled to vote such specified percentage in principal amount of the outstanding Notes shall constitute a quorum. In the
absence of a quorum within 30 minutes after the time appointed for any such meeting, the meeting shall, if convened at the request of Holders of Notes, be dissolved. In any other case the meeting may be adjourned for a period of not less than
10 days as determined by the chairman of the meeting prior to the adjournment of such meeting. In the absence of a quorum at the reconvening of any such adjourned meeting, such adjourned meeting may be further adjourned for a period of not less
than 10 days; at the reconvening of any meeting adjourned or further adjourned for lack of a quorum, the persons entitled to vote 25% in aggregate principal amount of the then outstanding Notes shall constitute a quorum for the taking of any
action set forth in the notice of the original meeting. Notice of the reconvening of any adjourned meeting shall be given as provided in Section 14.02(a), except that such notice need be given only once not less than five days prior to the date
on which the meeting is scheduled to be reconvened. 

  
 78 








 Except as limited by the proviso to Section 9.02, any resolution presented to a
meeting or adjourned meeting duly reconvened at which a quorum is present as aforesaid may be adopted by the affirmative vote of the persons entitled to vote a majority in aggregate principal amount of the outstanding Notes represented at such
meeting; provided, however, that, except as limited by the proviso to Section 9.02, any resolution with respect to any request, demand, authorization, direction, notice, consent, waiver or other action which this Indenture expressly
provides may be made, given or taken by the Holders of a specified percentage, which is less than a majority, in principal amount of the outstanding Notes may be adopted at a meeting or an adjourned meeting duly reconvened and at which a quorum is
present as aforesaid by the affirmative vote of the Holders of such specified percentage in principal amount of the outstanding Notes. 

Any resolution passed or decision taken at any meeting of Holders of Notes duly held in accordance with this Section 14.04 shall be
binding on all the Holders of Notes, whether or not present or represented at the meeting. 
 Notwithstanding the foregoing provisions of
this Section 14.04, if any action is to be taken at a meeting of Holders of Notes with respect to any request, demand, authorization, direction, notice, consent, waiver or other action that this Indenture expressly provides may be made, given
or taken by the Holders of a specified percentage in principal amount of all outstanding Notes affected thereby: 
 (i) there
shall be no minimum quorum requirement for such meeting; and 
 (ii) the principal amount of the outstanding Notes that vote
in favor of such request, demand, authorization, direction, notice, consent, waiver or other action shall be taken into account in determining whether such request, demand, authorization, direction, notice, consent, waiver or other action has been
made, given or taken under this Indenture. 
 Section 14.05. Determination of Voting Rights; Conduct and Adjournment of
Meetings. (a) Notwithstanding any provisions of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any meeting of Holders of Notes in regard to proof of the holding of Notes and of the appointment
of proxies and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall
deem appropriate. Except as otherwise permitted or required by any such regulations, the holding of Notes shall be proved in the manner specified in Section 8.01 and the appointment of any proxy shall be proved in the manner specified in
Section 8.01 or by having the signature of the Person executing the proxy witnessed or guaranteed by any trust company, bank or banker authorized by Section 8.01 to certify to the holding of the Notes. Such regulations may provide that
written instruments appointing proxies, regular on their face, may be presumed valid and genuine without the proof specified in Section 8.01 or other proof. 

(b) The Trustee shall, by an instrument in writing appoint a temporary chairman of the meeting, unless the meeting shall have been called by
the Issuer, the Company or by Holders of Notes as provided in Section 14.02(b), in which case the Issuer, the Company or the Holders of Notes calling the meeting, as the case may be, shall in like manner appoint a temporary


  
 79 








 
chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote a majority in principal amount of the outstanding Notes
represented at the meeting. 
 (c) At any meeting each Holder of such Notes or proxy shall be entitled to one vote for each $1,000 principal
amount of the outstanding Notes held or represented by him; provided, however, that no vote shall be cast or counted at any meeting in respect of any Note challenged as not outstanding and ruled by the chairman of the meeting to be not
outstanding. The chairman of the meeting shall have no right to vote, except as a Holder of Notes or proxy. 
 (d) Any meeting of Holders of
Notes duly called pursuant to Section 14.02 at which a quorum is present may be adjourned from time to time by Persons entitled to vote a majority in principal amount of the outstanding Notes represented at the meeting, and the meeting may be
held as so adjourned without further notice. 
 Section 14.06. Counting Votes and Recording Action of Meetings. The vote upon
any resolution submitted to any meeting of Holders of Notes shall be by written ballots on which shall be subscribed the signatures of the Holders of Notes or of their representatives by proxy and the principal amounts and serial numbers of the
outstanding Notes held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of
the meeting their verified written reports in duplicate of all votes cast at the meeting. A record, at least in duplicate, of the proceedings of each meeting of Holders of Notes shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more persons having knowledge of the fact, setting forth a copy of the notice of the meeting and showing that said
notice was given as provided in Section 14.02 and, if applicable, Section 14.04. Each copy shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one such copy shall be delivered to the
Issuer and the Company and another to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters therein stated.

 ARTICLE 15 
 REDEMPTION TO
PRESERVE REIT STATUS 
 Section 15.01. Redemption to Preserve REIT Qualification. 

No sinking fund shall be required for the Notes. The Notes shall not be redeemable by the Issuer prior to the Maturity Date except to the
extent necessary to preserve the Company’s qualification as a REIT for United States federal incomes tax purposes. If the Issuer determines that it is necessary to redeem the Notes prior to the Maturity Date to preserve the Company’s
qualification as a REIT, the Issuer may redeem (a “Redemption”) for cash all or part of the Notes as necessary to preserve the Company’s REIT qualification, at the Redemption Price. 

  
 80 








 Section 15.02. Notice of Redemption; Selection of Notes. 

(a) In case the Issuer exercises its right to redeem all or, as the case may be, any part of the Notes pursuant to Section 15.01, it
shall fix a date for redemption (each, a “Redemption Date”) and it or, at its written request received by the Trustee not less than 50 Scheduled Trading Days prior to the Redemption Date (or such shorter period of time as may
be acceptable to the Trustee), the Trustee, in the name of and at the expense of the Issuer, shall send a notice of such Redemption (a “Redemption Notice”) not less than 45 Scheduled Trading Days nor more than 75 calendar days
prior to the Redemption Date to each Holder of Notes so to be redeemed; provided, however, that, if the Issuer shall give such notice, it shall also give written notice of the Redemption Date to the Trustee. The Redemption Date must be a
Business Day. 
 (b) The Redemption Notice, if sent in the manner provided in herein, shall be conclusively presumed to have been duly
given, whether or not the Holder receives such notice. In any case, failure to give such Redemption Notice by mail, electronic delivery or otherwise or any defect in the Redemption 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. 
 (c) Each Redemption Notice shall
specify: 
 (i) the Redemption Date; 

(ii) the Redemption Price; 

(iii) that on the Redemption Date, the Redemption Price will become due and payable upon each Note to be redeemed, and that
Interest thereon, if any, shall cease to accrue on and after the Redemption Date (except as provided in the definition of Redemption Price with respect to a Redemption Date that falls after a Record Date but on or prior to the immediately succeeding
Interest Payment Date); 
 (iv) the place or places where such Notes are to be surrendered for payment of the Redemption
Price; 
 (v) that Holders may surrender their Notes for exchange at any time prior to the Close of Business on the Scheduled
Trading Day immediately preceding the Redemption Date; 
 (vi) the procedures a converting Holder must follow to exchange its
Notes and the Settlement Method and Specified Dollar Amount, if applicable; 
 (vii) the Exchange Rate and, if applicable,
the number of Additional Shares added to the Exchange Rate in accordance with Section 13.04; 
 (viii) the CUSIP or
other similar numbers, if any, assigned to such Notes; and 
 (ix) in case any Note is to be redeemed in part only, the
portion of the principal amount thereof to be redeemed and that on and after the Redemption Date, upon surrender of such Note, a new Note in principal amount equal to the unredeemed portion thereof shall be issued. 

  
 81 








 A Redemption Notice shall be irrevocable. 

(d) If fewer than all of the outstanding Notes are to be redeemed, the Trustee shall select the Notes or portions thereof 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 considers to be fair and appropriate and in each case subject to requirements of applicable law and of the applicable
Depositary. If any Note selected for redemption is submitted for exchange after such selection, the portion of the Note submitted for exchange shall be deemed (so far as may be possible) to be the portion selected for redemption. 

Section 15.03. Payment of Notes Called for Redemption. 

(a) If any Redemption Notice has been given in respect of the Notes in accordance with Section 15.02, the Notes shall become due and
payable on the Redemption Date at the place or places stated in the Redemption Notice and at the applicable Redemption Price, except as provided in the definition of Redemption Price with respect to a Redemption Date that falls after a Record Date
but on or prior to the immediately succeeding Interest Payment Date. On presentation and surrender of the Notes at the place or places stated in the Redemption Notice, the Notes shall be paid and redeemed by the Company at the applicable Redemption
Price. 
 (b) At or prior to 11:00 a.m., New York City time, on the Redemption Date, the Company shall deposit with the Paying Agent
or, if the Company or a Subsidiary of the Company is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 4.04 an amount of cash (in immediately available funds if deposited on the Redemption Date),
sufficient to pay the Redemption Price of all of the Notes to be redeemed on such Redemption Date. Subject to receipt of funds by the Paying Agent, payment for the Notes to be redeemed shall be made promptly after the later of: 

(i) the Redemption Date for such Notes; and 

(ii) the time of presentation of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder
thereof in the manner required by this Section 15.03. 
 The Paying Agent shall, promptly after such payment and upon written
demand by the Company, return to the Company any funds in excess of the Redemption Price. 
 Section 15.04. Effect of
Redemption. If by 11:00 a.m. New York City time, on the Redemption Date for a Redemption, the Trustee (or other Paying Agent appointed by the Issuer) holds money sufficient to make payment on all the Notes or portions thereof that are to be
redeemed on such Redemption Date, then, with respect to the Notes that have been called for such Redemption, (i) such Notes will cease to be outstanding, (ii) Interest will cease to accrue on such 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), except to the extent set forth in the definition of Redemption Price with respect to a Redemption Date that falls after a Record Date but on or prior to the
immediately succeeding Interest Payment Date, and (iii) all other rights of the Holders of such Notes will terminate (other than the right to receive the Redemption Price). 

  
 82 








 Section 15.05. Restrictions on Redemption. The Issuer may not redeem any Notes on any
date if the principal amount of the Notes has been accelerated in accordance with the terms of this Indenture, and such acceleration has not been rescinded, on or prior to the Redemption Date (except in the case of an acceleration resulting from a
Default by the Issuer in the payment of the Redemption Price with respect to such Notes).

 [FORM OF REVERSE SIDE OF NOTE] 

EMPIRE STATE REALTY OP, L.P. 

2.625% EXCHANGEABLE SENIOR NOTES DUE 2019 

This Note is one of a duly authorized issue of Notes of the Issuer, designated as its 2.625% Exchangeable Senior Notes due 2019 (herein
called the “Notes”), issued under and pursuant to an Indenture dated as of August 12, 2014 (herein called the “Indenture”), among the Issuer, the Company and Wilmington Trust, National Association, as trustee
(herein called the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee,
the Issuer and the Holders of the Notes. Capitalized terms used but not otherwise defined in this Note shall have the respective meanings ascribed thereto in the Indenture. If there is any conflict between the terms of the Indenture and this Note,
the terms of the Indenture shall govern. 
 If an Event of Default (other than an Event of Default specified in
Section 6.01(a)(10) or 6.01(a)(11) of the Indenture with respect to the Issuer or the Company) occurs and is continuing, unless the principal of all the Notes shall have already become due and payable, either the Trustee or the Holders of at
least twenty-five percent (25%) in aggregate principal amount of the Notes then outstanding, by notice in writing to the Issuer and the Company (and to the Trustee if given by Noteholders), may declare the principal amount of and Interest
accrued and unpaid on all the Notes to be immediately due and payable. If an Event of Default specified in Section 6.01(a)(10) or 6.01(a)(11) of the Indenture with respect to the Issuer or the Company occurs and is continuing, then the
principal amount of and Interest accrued and unpaid on all the Notes shall be immediately due and payable without any declaration or other action on the part of the Trustee or any Holder of Notes. 

The Indenture contains provisions permitting the Issuer and the Trustee, with the consent of the Holders of not less than a majority in
aggregate principal amount of the Notes at the time outstanding, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or
modifying in any manner the rights of the Holders of the Notes, subject to exceptions set forth in Section 9.01 and Section 9.02 of the Indenture. Subject to the provisions of the Indenture, the Holders of not less than a majority in
aggregate principal amount of the Notes at the time outstanding may, on behalf of the Holders of all of the Notes, waive any past default or Event of Default, subject to the exceptions set forth in the Indenture. 

No reference herein to the Indenture and no provision of this Note or of the Indenture shall impair, as among the Issuer and the Holder of the
Notes, the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and Interest on this Note at the place, at the respective times, at the rate and in the coin or currency herein and in the Indenture prescribed. 

Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months and, for partial months, on the basis of the number of days actually elapsed in a 30-day month. 

  
 A-5 








 The Notes are issuable in fully registered form, without coupons, in minimum denominations of
$1,000 principal amount and in integral multiples of $1,000 in excess thereof. At the office or agency of the Issuer referred to in the Indenture, and in the manner and subject to the limitations provided in the Indenture, without payment of any
service charge but with payment of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration or exchange of Notes, Notes may be exchanged for a like aggregate principal amount
of Notes of any other authorized denominations. 
 The Notes are subject to redemption in to preserve the Company’s REIT qualification
as described under Article 15 of the Indenture. No sinking fund is provided for the Notes. 
 Upon the occurrence of a Fundamental Change,
Holders shall have the right to require the Issuer to repurchase all or a portion of their Notes pursuant to Section 3.02 of the Indenture. 

Subject to and in compliance with the provisions of the Indenture, the Holder hereof shall have the right at its option to exchange each
$1,000 principal amount of this Note into cash, shares of Common Stock or a combination of cash and shares of Common Stock, at the election of the Issuer as provided in, and subject to the provisions of, Article 13 of the Indenture. 

In the event the Holder surrenders this Note for exchange in connection with a Make-Whole Fundamental Change as set forth in the Indenture,
the Issuer will, under the circumstances specified in the Indenture, increase the applicable Exchange Rate by the Additional Shares as and when provided in the Indenture. 

No recourse under or upon any obligation, covenant or agreement contained in the Indenture, in this Note or the Registration Rights Agreement,
or because of any indebtedness evidenced by any of the foregoing, shall be had against any past, present or future partner (including the Company), shareholder, member, manager, employee, officer, agent or director, solely in their capacity as such,
of the Company or the Issuer, as applicable, or any such predecessor or successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such
liability being expressly waived and released by the acceptance of the Notes by the Holders as part of the consideration for the issue of the Notes. 

In addition to the rights provided to Holders of Notes under the Indenture, Holders shall have all the rights set forth in the
Registration Rights Agreement dated as of August 12, 2014, among the Issuer, the Company and the Initial Purchaser named therein (the “Registration Rights Agreement”). 

This Note shall be governed by, and construed in accordance with, the laws of the State of New York.
