DEFAULTS AND REMEDIES 

Section 5.01 Events of Default. Solely for purposes of the Notes, Section 8.01 of the Base Indenture shall be replaced
in its entirety with the following:

(vii) default by the Company or any Subsidiary of the Company with respect to any mortgage, agreement or other instrument
under which there may be outstanding, or by which there may be secured or evidenced, any indebtedness for money borrowed in excess of $50 million in the aggregate of the Company and/or of any such Subsidiary, whether such indebtedness now
exists or shall hereafter be created (i) resulting in such indebtedness becoming or being declared due and payable (unless such declaration has been rescinded) or (ii) constituting a failure to pay the principal of or interest on any such
indebtedness when due and payable at its stated maturity, upon required repurchase, upon declaration of acceleration or otherwise; 
 (viii) a final judgment for the payment of $10 million or more (excluding any amounts covered by insurance) rendered against the Company or any Significant Subsidiary of the Company, 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; 

(ix) the Company or any Significant Subsidiary of the Company or any group of Subsidiaries of the Company that in the
aggregate would constitute a Significant Subsidiary shall commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to the Company or such Significant Subsidiary or such group of Subsidiaries or
its or their debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or any such Significant Subsidiary
or any such group of Subsidiaries or any substantial part of its or their property, or shall consent to any such relief or to the appointment of or taking possession by any such official in an involuntary case or other proceeding commenced against
it or them, or shall make a general assignment for the benefit of creditors, or shall fail generally to pay its or their debts as they become due; 
 (x) an involuntary case or other proceeding shall be commenced against the Company or any Significant Subsidiary of the Company or any group of Subsidiaries of the Company that in the aggregate would

(xi) except as permitted by this Indenture, any Subsidiary Guarantee shall be held in any judicial proceeding to be
unenforceable or invalid for any reason or shall cease for any reason to be in full force and effect, or any Subsidiary Guarantor, or any Person acting on its behalf, shall deny or disaffirm such Subsidiary Guarantor’s obligation under its
Subsidiary Guarantee. 
 (b) In case one or more Events of Default shall have occurred and be continuing
(whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or
governmental body), then, and in each and every such case (other than an Event of Default specified in Section 8.01(ix) or Section 8.01(x) with respect to the Company or any of its Significant Subsidiaries or any group of its Subsidiaries
that in the aggregate would constitute a Significant Subsidiary), 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 Company (and to the Trustee if given by Holders), may, and the Trustee at the request of Holders of at least 25% in aggregate principal amount of the Notes then Outstanding shall, declare 100% of the
principal of, and accrued and unpaid interest, if any, on, all the Notes to be due and payable, and upon any such declaration the same shall become and shall automatically be immediately due and payable, anything in this Indenture or in the Notes
contained to the contrary notwithstanding. If an Event of Default specified in Section 8.01(ix) or Section 8.01(x) with respect to the Company or any of its Significant Subsidiaries or any group of its Subsidiaries that in the aggregate
would constitute a Significant Subsidiary occurs and is continuing, 100% of the principal of, and accrued and unpaid interest, if any, on, all Notes shall become and shall automatically be immediately due and payable. 

(c) Section 8.01(b), however, is subject to the conditions that if, at any time after the principal of 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, the Company shall pay or shall deposit with the Trustee a sum sufficient to
pay installments of accrued and unpaid interest upon all Notes and the principal of any and all Notes that shall have become due otherwise than by acceleration (with interest on overdue installments of accrued and unpaid interest to the extent that
payment of such interest is enforceable under applicable law, and on such principal at the rate borne by the Notes plus one percent at such time) and amounts due to the Trustee pursuant to Section 9.06, and if (1) rescission would
not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of Default under this Indenture, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes
that shall have become due solely by such acceleration, shall have been cured or waived, then and in every such case the Holders of a majority of the aggregate principal amount of the Notes then Outstanding, by written notice to the Company and to
the Trustee, may rescind and annul any consequence of any such Default or Events of Default, including such declaration and its consequences, and any 

  
 14 

 
Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but 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. 
 (d) 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, by written notice to the Company and the Trustee, waive any past Default or Event of Default hereunder except (i) a default in the
payment of accrued and unpaid interest, if any, on, or the principal (including any Fundamental Change Purchase Price) of, the Notes when due that has not been cured pursuant to the provisions of Section 6.01, (ii) a failure by the Company
to pay or deliver, as the case may be, the consideration due upon conversion of the Notes or (iii) a default in respect of a covenant or provision hereof which under Section 10.2 cannot be modified or amended without the consent of each
Holder of an outstanding Note affected. Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default
or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 8.01, said Default or Event of Default shall for all purposes of the Notes and
this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. 

Section 5.02 Additional Interest. Solely with respect to the Notes, the Base Indenture shall be amended by adding the
following Section immediately after Section 8.11 of the Base Indenture: 
 SECTION 8.12. Additional
Interest. Notwithstanding anything in this Indenture or in the Notes to the contrary, if the Company so elects, the sole remedy during the 90-day period specified below for an Event of Default relating to the Company’s failure to comply
with its obligations as set forth in Section 4.01(a) or Section 4.01(b) of the Supplemental Indenture for the Notes shall, after the occurrence of such Event of Default, consist exclusively of the right to receive Additional Interest on
the Notes at a rate equal to 0.25% per annum of the principal amount of the Notes outstanding for each day (x) during the 90-day period beginning on, and including, the occurrence of such Event of Default and (y) on which such Event
of Default is continuing. If the Company so elects, such Additional Interest shall be payable in the same manner and on the same dates as regular interest on the Notes. On the 91st day after such Event of Default (if such Event of Default is not
cured or waived prior to such 91st day), the Notes shall be subject to acceleration as provided in Section 8.01. For the avoidance of doubt, this Section 8.12 shall not affect the rights of Holders in the event of the occurrence of any
Event of Default other than an Event of Default described in the first sentence of this Section 8.12. In the event the Company does not elect to pay Additional Interest following an Event of Default in accordance with this Section 8.12,
the Notes shall be immediately subject to acceleration as provided in Section 8.01. 
 In order to elect to
pay Additional Interest as the sole remedy during the first 90 days after the occurrence of any Event of Default described in the immediately 

  
 15 

 
preceding paragraph, the Company must notify in writing all Holders of the Notes, the Trustee and the Paying Agent of such election prior to the beginning of such 90-day period. Upon the
Company’s failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 8.01. 
 ARTICLE 6

 Upon the written request of the Company, the Trustee is hereby authorized to join with the Company and the Subsidiary Guarantors in the execution of any such supplemental indenture, to make any further
appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to, but may in its discretion, enter into any supplemental indenture that affects the Trustee’s own rights, duties or immunities under
this Indenture or otherwise. 
 Any supplemental indenture authorized by the provisions of this
Section 10.01 may be executed by the Company, any Subsidiary Guarantor and the Trustee without the consent of the Holders of any of the Notes at the time outstanding, notwithstanding any of the provisions of Section 10.02. 

Section 6.02 Modification of Indenture with Consent of Holders of at Least a Majority in Principal Amount of Outstanding
Securities. Solely for purposes of the Notes, Section 10.02 of the Base Indenture shall be replaced in its entirety with the following: 
 SECTION 10.02. Modification of Indenture with Consent of Holders of at Least a Majority in Principal Amount of Outstanding Securities. With the consent of the Holders of at least a majority of the
aggregate principal amount of the Notes then Outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), the Company and any Subsidiary Guarantor, when authorized by
a Board Resolution, and the Trustee, at the Company’s expense, may from time to time and at any time enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Indenture or any supplemental indenture or of modifying in any manner the rights of the Holders; provided, however, that, without the consent of each Holder of an outstanding Note affected, no such

 Upon the written request of the Company, and upon the filing with the Trustee of evidence of the consent of Holders as aforesaid and subject to Section 10.03, the Trustee shall join with the Company
and the Subsidiary Guarantors in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its
discretion, but shall not be obligated to, enter into such supplemental indenture. 
 The consent of the Holders
is not necessary under this Section 10.02 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if the required number of Holders approve the substance thereof. After any such supplemental indenture
becomes effective, the Company shall mail to the Holders a notice briefly describing such supplemental indenture; provided that the failure to give such notice to all the Holders, or any defect in such notice, shall not impair or affect the
validity of the supplemental indenture. 
 ARTICLE 7 
 CONSOLIDATION, MERGER, SALE, OR TRANSFER 
 Section 7.01 Consolidations and Mergers of Company and Sales Permitted Only on Certain Terms. Solely for purposes of the Notes, Section 11.01(a) of the Base Indenture is hereby replaced
in its entirety with the following: 
 SECTION 11.01. Consolidations and Mergers of Company and Sales
Permitted Only on Certain Terms. (a) The Company shall not consolidate with or merge with or into any other Person, or transfer (by lease, assignment, sale, or otherwise) all or substantially all of its properties and assets to another
Person unless (i) either (A) the Company shall be the continuing or surviving Person in such a consolidation or merger or 

  
 18 

 
(B) the Person (if other than the Company) formed by such consolidation or into which the Company is merged or to which all or substantially all of the properties and assets of the Company
are transferred (the Company or such other Person being referred to as the “Surviving Person”) shall be a corporation organized and validly existing under the laws of the United States, any state thereof, or the District of
Columbia, and shall expressly assume, by an indenture supplement, all the obligations of the Company under the Securities and the Indenture, (ii) immediately after the transaction and the incurrence or anticipated incurrence of any Indebtedness
to be incurred in connection therewith, no Event of Default will exist, (iii) if as a result of such transaction the Notes become convertible into, or the Daily VWAP is calculated by reference to, common stock or other securities issued by a
third party (subject to the provisions of Section 8.02 of the Supplemental Indenture for the Notes), such third party fully and unconditionally guarantees all obligations of the Company or such Surviving Person under the Notes and such
supplemental indenture, unless such guarantee is not required for any shares of the Common Stock issuable upon conversion of the Notes to be freely tradable under U.S. securities law and (iv) an Officer’s Certificate has been delivered to
the Trustee to the effect that the conditions set forth in the preceding clauses (i) and (ii) have been satisfied and an Opinion of Counsel (from a counsel who shall not be an employee of the Company) has been delivered to the Trustee to
the effect that the conditions set forth in the preceding clause (i) have been satisfied. 
 ARTICLE 8 

CONVERSION OF NOTES 
 Section 8.01 Conversion Privilege. (a) Subject to and upon compliance with the provisions of this Article 8, each Holder of a Note shall have the right, at such Holder’s option, to
convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Note (i) subject to satisfaction of one or more of the conditions described in Section 8.01(b), at any time
prior to the close of business on the Business Day immediately preceding April 15, 2019, under the circumstances and during the periods set forth in Section 8.01(b), and (ii) regardless of whether any of the conditions set forth in
Section 8.01(b) has been met, on or after April 15, 2019, and prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, in each case, at the applicable Conversion Rate (subject to the
settlement provisions of Section 8.02, the “Conversion Obligation”). 
 (b)(i) Prior to the close of
business on the Business Day immediately preceding April 15, 2019, the Notes shall be convertible during the five Business Day period immediately after any five consecutive Trading Day period (the “Measurement Period”) in which
the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder of Notes in accordance with this subsection (b)(i) and the definition of Trading Price, for each Trading Day of such Measurement Period was less
than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on such Trading Day (the “Trading Price Condition”). The Trading Prices shall be determined by the Bid Solicitation Agent pursuant
to this subsection (b)(i) and the definition of Trading Price. The Company shall provide written notice to the Bid Solicitation Agent of the three independent nationally 

  
 19 

 
recognized securities dealers selected by the Company 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 of the Notes unless the Company has requested such determination, and the Company shall have no obligation to make such request unless a Holder provides the Company with reasonable evidence that the Trading
Price per $1,000 principal amount of the Notes would be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate, at which time the Company shall instruct the Bid Solicitation Agent to
determine the Trading Price of the Notes in the manner described in this subsection (b)(i) and the definition of Trading Price beginning on the next Trading Day following the receipt of such evidence and on each successive Trading Day until the
Trading Price per $1,000 principal amount of the Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on such Trading Day. If the Company does not instruct the Bid
Solicitation Agent to determine the Trading Price of the Notes, or if the Company gives such instruction to the Bid Solicitation Agent, and the Bid Solicitation Agent fails to make such determination, in each case when the Company or the Bid
Solicitation Agent, as the case may be, is obligated to do so pursuant to the preceding sentence, 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 applicable Conversion Rate on each Trading Day of such failure. If the Trading Price Condition has been met, the Company shall so notify the Holders, the Trustee and the Conversion Agent (if other than the
Trustee) within one Business Day. If, at any time after the Trading Price Condition has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common
Stock and the applicable Conversion Rate, the Company shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) within one Business Day. 
 (ii) If, prior to the close of business on the Business Day immediately preceding April 15, 2019, the Company elects to: 

(A) issue to all or substantially all holders of the Common Stock any rights, options or warrants entitling them, for a
period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock, at a price per share that is less than the average of the Last Reported Sale Prices of the Common Stock
for the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance; or 
 (B) distribute to all or substantially all holders of the Common Stock the Company’s assets, debt securities or certain rights to purchase securities of the Company, which distribution has a value
per share of the Common Stock, as reasonably determined by the Board of Directors, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day preceding the date of announcement for such distribution, 

then, in either case, the Company shall notify in writing all Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) at
least 35 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice,

the Notes shall be convertible at any time until the earlier of (1) the close of business on the Business Day immediately preceding such Ex-Dividend Date and (2) the Company’s
announcement that such issuance or distribution will not take place, even if the Notes are not otherwise convertible at such time. Holders of the Notes shall not have the right to convert their Notes solely due to this Section 8.01(b)(ii) if
each Holder will have the right to participate (as a result of holding the Notes, and at the same time and on the same terms as holders of Common Stock participate) in any of the transactions described in this Section 8.01(b)(ii) as if such
Holder of the Notes held a number of shares of the Common Stock equal to (i) the applicable Conversion Rate, multiplied by (ii) (x) the principal amount of Notes held by such Holder divided by (y) $1,000, without
having to convert its Notes. 
 (iii) 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 April 15, 2019, regardless of whether a Holder has the right to require the Company to purchase such Holder’s Notes pursuant to
Section 9.01, or if the Company is a party to a consolidation, merger, binding share exchange, sale, conveyance, transfer or lease of all or substantially all of the Company’s assets, pursuant to which the Common Stock would be converted
into cash, securities or other assets, the Notes may be surrendered for conversion at any time from or after the Business Day following the effective date of the transaction until 35 Trading Days after the effective date of such transaction or, if
such transaction also constitutes a Fundamental Change, until the related Fundamental Change Purchase Date. The Company shall notify in writing all Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such transaction no
later than the effective date of such transaction. 
 (iv) Prior to the close of business on the Business Day immediately
preceding April 15, 2019, the Notes shall be convertible during any calendar quarter commencing after June 30, 2013, (and only during such calendar quarter), if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days
(whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar quarter is greater than or equal to 130% of the applicable Conversion Price on each applicable Trading
Day. The Company shall determine at the beginning of each calendar quarter commencing after May 31, 2013 whether the Notes may be surrendered for conversion in accordance with this clause (iv) and shall notify in writing the Company and
the Trustee on or prior to the fifth Business Day of the Notes becoming convertible in accordance with this clause (iv). 

Section 8.02 Conversion Procedure; Settlement Upon Conversion. (a) Except as provided in Section 8.03(b), upon any
conversion of any Note, the Company shall pay or deliver, as the case may be, to converting Holders, in respect of its Conversion Obligation, (i) shares of Common Stock, together with cash, if applicable, in lieu of any fractional share of
Common Stock in accordance with subsection (i) of this Section 8.02 (“Physical Settlement”), (ii) a cash payment without any delivery of shares of Common Stock (“Cash Settlement”), or (iii) a
combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of any fractional share of Common Stock in accordance with subsection (i) of this Section 8.02 (“Combination Settlement”), at its
election, as set forth in this Section 8.02. 

  
 21 

 (i) Prior to the close of business on the Business Day immediately preceding
April 15, 2019, the Company shall use the same Settlement Method for all conversions occurring on the same Conversion Date, provided that, prior to April 15, 2019, the Company shall not have any obligation to use the same Settlement
Method with respect to conversions that occur on different Conversion Dates. 
 (ii) For conversions: 

(A) that occur prior to the close of business on the Business Day immediately preceding April 15, 2019, by the close
of business on the Business Day following the Conversion Date, the Company shall deliver a notice to converting Holders of the relevant Settlement Method in respect of such Conversion Date and, if the Company elects Combination Settlement, the
related Cash Amount; and 
 (B) that occur on or after April 15, 2019, the Company shall deliver a notice to
all Holders of the relevant Settlement Method and, if the Company elects Combination Settlement, the related Cash Amount, prior to the close of business on the Business Day immediately preceding April 15, 2019 (which Settlement Method and Cash
Amount, if applicable, will apply to all conversions on or after April 15, 2019). 
 Any Settlement Notice delivered pursuant to clause
(A) or (B) of this Section 8.02(a)(ii) may not be revoked. 
 (iii) If the Company does not
deliver a Settlement Notice with respect to any conversion of a Note in accordance with Section 8.02(a)(ii), then the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation and the related Cash
Amount shall be deemed to be $1,000. If the Company delivers a Settlement Notice with respect to the conversion of a Note in accordance with Section 8.02(a)(ii) electing Combination Settlement as the Settlement Method and does not indicate the
Cash Amount, such Cash Amount shall be deemed to be $1,000. 
 (iv) With respect to any shares of Common Stock
that are issuable upon conversion: 
 (A) if Physical Settlement applies, the Person in whose name the
certificate or certificates for such shares of Common Stock shall be registered shall become the holder of record of such shares of Common Stock as of the close of business on the relevant Conversion Date; and 

(B) if Combination Settlement applies, the Person in whose name the certificate or certificates for such shares of Common
Stock shall be registered shall become the holder of record of such shares of Common Stock as of the close of business on the last Trading Day of the related Observation Period. 

  
 22 

 Upon a conversion of Notes, the Holder who surrendered such Notes for conversion shall no
longer be a Holder of such Notes. 
 (v) If Physical Settlement applies to any Notes surrendered for conversion,
the Company shall deliver to the converting Holder (subject to Section 8.02(c)), for each $1,000 principal amount of Notes being converted, a number of shares of Common Stock equal to the applicable Conversion Rate as of the relevant Conversion
Date, together with cash in lieu of fractional shares of Common Stock pursuant to Section 8.02(i). Subject to Section 8.03(b), the Company shall deliver such shares of Common Stock on the third Business Day following the Conversion Date.

 (vi) If Cash Settlement applies to any Notes surrendered for conversion, the Company shall pay to the
converting Holder, for each $1,000 principal amount of Notes being converted, an amount of cash equal to the sum of the Daily Conversion Values for each Trading Day during the relevant Observation Period. Subject to Section 8.03(b), the Company
shall make such payment on the third Business Day following the last Trading Day of the applicable Observation Period. 
 (vii) If Combination Settlement applies to any Notes surrendered for conversion, the Company shall pay or deliver, as the case may be, to the converting Holder (subject to Section 8.02(c)) for each
$1,000 principal amount of Notes being converted, the sum of the Daily Settlement Amounts for each Trading Day during the relevant Observation Period. Subject to Section 8.03(b), the Company shall deliver the cash and shares of Common Stock
comprising its Conversion Obligation pursuant to the preceding sentence on the third Business Day following the last Trading Day of the applicable Observation Period. 

(viii) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by
the Company promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash deliverable in lieu of any fractional
share pursuant to Section 8.02(i), the Company shall notify in writing the Trustee and the Conversion Agent (if other than the Trustee) of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash
deliverable in lieu of fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination. 

(b) Before any holder of a beneficial interest in a Global Note shall be entitled to convert such beneficial interest as set forth above,
such holder shall comply with the procedures of the Depositary for converting a beneficial interest in a global note in effect at that time and, if required, pay funds equal to any interest payable on the next Interest Payment Date to which such
holder is not entitled as set forth in Section 8.02(h) and, if required, all documentary, stamp or similar issue or transfer taxes, if any, as required by Section 8.02(d) or Section 8.02(e). In the case of a Physical Note, before the
Holder thereof shall be entitled to convert such Note as set forth above, such Holder shall (1) complete, manually sign and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile
thereof) 

  
 23 

 
(a “Notice of Conversion”) at the office of the Conversion Agent and state in writing therein the principal amount of such Note to be converted and the name or names (with
addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Note, duly endorsed to the Company or in
blank at the office of the Conversion Agent, (3) if required, pay funds equal to any interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 8.02(h), (4) if required, furnish
appropriate endorsements and transfer documents and (5) if required, pay all documentary, stamp or similar issue or transfer taxes, if any, as required by Section 8.02(d) or Section 8.02(e). The Conversion Agent shall notify the
Company of any conversion pursuant to this Article 8 on the Conversion Date for such conversion. No Notice of Conversion with respect to any Note may be delivered by the Holder thereof if such Holder has also delivered a Fundamental Change
Purchase Notice to the Company in respect of such Note and not validly withdrawn such Fundamental Change Purchase Notice in accordance with Section 9.03. 
 If more than one Note shall be surrendered for conversion at one time by the same Holder, the Conversion Obligation with respect to such Notes 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. 
 (c) A Note shall be
deemed to have been converted immediately prior to the close of business on the date (the “Conversion Date”) that the Holder has complied with the requirements set forth in subsection (b) above. If any shares of Common Stock
are due to converting Holders, the Company shall issue or cause to be issued, and deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the full
number of shares of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation. 
 (d) In case any Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so
surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note, without payment of any service charge by the converting Holder but, if required by the Company or
Trustee, with payment of a sum sufficient to cover any transfer tax or similar governmental charge required by law or that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion
being different from the name of the Holder of the old Notes surrendered for such conversion. 
 (e) If a Holder submits a Note
for conversion in accordance with Section 8.02, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of any shares of Common Stock upon such conversion, unless such tax is due because such Holder
requests such shares to be issued in a name other than such Holder’s name, in which case such Holder shall pay such tax. The Conversion Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name
other than the Holder’s name until the Trustee receives a sum sufficient to pay any such tax that is due by such Holder in accordance with the immediately preceding sentence. 

  
 24 

 (f) Except as provided in Section 8.04, no adjustment shall be made for dividends on
any shares issued upon the conversion of any Note as provided in this Article 8. 
 (g) Upon the conversion of an interest
in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any
conversion of Notes effected through any Conversion Agent other than the Trustee. 
 (h) Upon conversion, a Holder shall not
receive any separate cash payment or additional shares of Common Stock representing accrued and unpaid interest, if any, except as set forth below. Upon conversion of any Note, the Company’s settlement of the Conversion Obligation with respect
to such Note shall be deemed to satisfy in full its obligation to pay the principal amount of such Note and accrued and unpaid interest, if any, on such Note to, but not including, the Conversion Date. As a result, accrued and unpaid interest, if
any, on such Note to, but not including, the Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of Notes into a combination of cash and shares of Common Stock, accrued and unpaid
interest, if any, shall be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular Record Date and prior to the open of business on the
corresponding Interest Payment Date, Holders of such Notes as of the close of business on such Regular Record Date shall receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding such
conversion. Notes surrendered for conversion during the period from the close of business on any Regular Record Date to the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of
interest payable on the Notes so converted; provided that no such payment shall be required (1) if such Notes are surrendered for conversion after the close of business on the Regular Record Date immediately preceding the Maturity Date;
(2) if the Company has specified a Fundamental Change Purchase Date that is after a Regular Record Date and on or prior to the second Scheduled Trading Day immediately following the corresponding Interest Payment Date; or (3) to the extent
of any Defaulted Amounts, if any Defaulted Amounts exist at the time of conversion with respect to such Note. 
 (i) The Company
shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash in lieu of any fractional share of Common Stock issuable upon conversion. If Physical Settlement applies, the amount of such cash shall be
based on the Daily VWAP of the Common Stock on the relevant Conversion Date. If Combination Settlement applies, the amount of such cash shall be based on the Daily VWAP of the Common Stock on the last Trading Day of the applicable Observation
Period. If Combination Settlement applies, for each Note surrendered for conversion the full number of shares of Common Stock that shall be issued upon conversion thereof shall be calculated on the basis of the aggregate Daily Settlement Amounts for
the applicable Observation Period and any fractional shares of Common Stock remaining after such calculation shall be paid in cash. In addition, if more than one Note shall be surrendered for conversion at one time by the same Holder, the number of
full shares of Common Stock, if any, that shall be issued upon conversion thereof shall be calculated on the basis of the aggregate principal amount of the Notes (or specified portions thereof) so surrendered. 

  
 25 

 Section 8.03 Increased Conversion Rate Applicable to Certain Notes Surrendered in
Connection with Make-Whole Fundamental Changes. (a) If a Make-Whole Fundamental Change occurs prior to the Maturity Date and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall,
under the circumstances described below, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described below. A conversion of Notes
shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the Effective Date of the Make-Whole Fundamental
Change up to, and including, the Business Day immediately prior to the related Fundamental Change Purchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause
(2) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change). 
 (b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change pursuant to Section 8.01(b)(iii), the Company shall pay or deliver, as the case may be, shares of Common
Stock, cash or a combination of cash and shares of Common Stock in accordance with Section 8.02; provided, however, that if, at the effective time of a Make-Whole Fundamental Change described in clause (2) of the definition
of Fundamental Change, the Reference Property is comprised entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the consideration due upon conversion shall be an amount of cash per $1,000
principal amount of converted Notes equal to the applicable Conversion Rate (including any adjustment for Additional Shares), multiplied by the Stock Price for such Make-Whole Fundamental Change. In such event, the Conversion Obligation shall
be determined as of the relevant Conversion Date and paid to Holders in cash on the third Business Day following such Conversion Date. The Company shall notify the Holders of Notes of the Effective Date of any Make-Whole Fundamental Change and issue
a press release announcing such Effective Date no later than five Business Days after such Effective Date. 
 (c) The number of
Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table in subsection (e) below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the
“Effective Date”) and the price (the “Stock Price”) paid (or deemed paid) per share of the Common Stock in the Make-Whole Fundamental Change. If the holders of the Common Stock receive only cash in a Make-Whole
Fundamental Change described in clause (2) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock
over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change. 
 (d) The Stock Prices set forth in the column headings of the table in subsection (e) below shall be adjusted as of any date on which the Conversion Rate is otherwise adjusted. The adjusted Stock
Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the
denominator of which is 

  
 26 

 
the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table below shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth in
Section 8.04. 
 (e) The following table sets forth the number of Additional Shares to be added to the Conversion Rate
pursuant to this Section 8.03 for each Stock Price and Effective Date set forth below:

 The exact Stock Prices and Effective Dates may not be set forth in the table above, in which case:

 (i) if the Stock Price is between two Stock Prices in the table above or the Effective Date is between two
Effective Dates in the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices or the earlier and later Effective Dates based
on a 365-day year, as applicable; 
 (ii) if the Stock Price is greater than $100.00 per share (subject to
adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to clause (d) above), no Additional Shares shall be added to the Conversion Rate; and 

(iii) if the Stock Price is less than $30.16 per share (subject to adjustment in the same manner as the Stock Prices set
forth in the column headings of the table above pursuant to clause (d) above), no Additional Shares shall be added to the Conversion Rate. 

Notwithstanding the foregoing, in no event shall the total number of shares of Common Stock issuable upon conversion exceed 33.1564 per $1,000
principal amount of Notes, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 8.04 and subject to Section 8.12. 

  
 27 

 (f) Nothing in this Section 8.03 shall prevent an adjustment to the Conversion Rate
pursuant to Section 8.04 in respect of a Make-Whole Fundamental Change. 
 Section 8.04 Adjustment of Conversion
Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustment to the Conversion Rate if Holders of the Notes participate (other than in
the case of a share split or share combination), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section 8.04, without having to
convert their Notes, as if they held a number of shares of Common Stock equal to (i) the Conversion Rate in effect immediately prior to the effective time for such adjustment, multiplied by (ii) (x) the principal amount of
Notes held by such Holder divided by (y) $1,000. 
 (a) If the Company exclusively issues shares of Common Stock as
a dividend or distribution on shares of the Common Stock, or if the Company effects a share split or share combination, the Conversion Rate shall be adjusted based on the following formula: 

 
 

 
 where, 
  

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

 Any adjustment made under this Section 8.04(a) shall become effective immediately after the open of business on the
Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the Distribution Effective Date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this
Section 8.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would
then be in effect if such dividend or distribution had not been declared. 

  
 28 

 (b) If the Company issues to all or substantially all holders of the Common Stock any
rights, options or warrants entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less than the average of
the Last Reported Sale Prices of the Common Stock for the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be increased based on
the following formula: 
  
 

 
 where, 
  

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

 Any increase made under this Section 8.04(b) shall 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-Dividend Date for such issuance. To the extent that shares of the Common Stock are not delivered after the expiration of such rights, options or
warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of
Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred.

 For purposes of Section 8.01(b)(ii)(A) and this Section 8.04(b), in determining whether any rights, options or
warrants entitle the holders thereof to subscribe for or purchase shares of Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for the ten 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 

  
 29 

 
into account any consideration received by 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. 
 (c) If the Company distributes shares of its Capital Stock, evidences
of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire Capital Stock or other securities of the Company, to all or substantially all holders of the Common Stock, excluding (i) dividends,
distributions or issuances as to which an adjustment was effected pursuant to Section 8.04(a) or Section 8.04(b), (ii) dividends or distributions paid exclusively in cash (as set forth in Section 8.04(d)), and
(iii) Spin-Offs to which the provisions set forth below in this Section 8.04(c) shall apply (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock
or other securities of the Company, the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula: 
  

 
 where, 
  

							
	
CR0
	  	 	=	  	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;
			
	
CR1
	  	 	=	  	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	
SP0
	  	 	=	  	  	the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the
Ex-Dividend Date for such distribution; and
			
	 FMV
	  	 	=	  	  	the fair market value (as determined by the Board of Directors) of the Distributed Property with respect to each outstanding share of Common Stock on the Ex-Dividend Date for
such distribution.

 If the Board of Directors determines the “FMV” (as defined above) of any distribution for
purposes of this Section 8.04(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the same period used in computing the Last Reported Sale Prices of the
Common Stock over the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or
greater than “SP0” (as defined above), in lieu of
the foregoing increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock receive the Distributed Property, the amount and kind of
Distributed Property such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for such distribution. 

  
 30 

 Any increase made under the portion of this Section 8.04(c) above shall 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 Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such
distribution had not been declared. If such a distribution of rights, options or warrants to acquire shares of Capital Stock or other securities of the Company is made, to the extent that shares of Capital Stock or other securities of the Company
are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants
been made on the basis of delivery of only the number of shares of Capital Stock or other securities of the Company actually delivered. 
 With respect to an adjustment pursuant to this Section 8.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or
series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, in each case listed on a national or regional securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based
on the following formula: 
  
 

 
 where, 
  

							
	
CR0
	  	 	=	  	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such Spin-Off;
			
	
CR1
	  	 	=	  	  	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such Spin-Off;
			
	 FM V0
	  	 	=	  	  	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common
Stock (determined for purposes of the definition of Last Reported Sale Price as if such Capital Stock or similar equity interest were Common Stock) over the first ten consecutive Trading Day period beginning on, and including, the Ex-Dividend Date
of the Spin-Off (the “Valuation Period”); and
			
	
MP0
	  	 	=	  	  	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

 The increase to the Conversion Rate under the preceding paragraph shall be determined on the last Trading Day of the
Valuation Period but shall be given effect immediately after the open of business on the Ex-Dividend Date for such Spin-Off; provided that in respect of any conversion during the Valuation Period, references in the portion of this
Section 8.04(c) related to Spin-Offs to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date of such Spin-Off to, and including, the Conversion Date in
determining the applicable Conversion Rate. If the Ex-Dividend Date for 

  
 31 

 
such Spin-Off is less than 10 Trading Days prior to, and including, the end of the Observation Period in respect of any conversion, references in the portion of this Section 8.04(c) related
to Spin-Offs to 10 Trading Days shall be deemed replaced, for purposes of calculating the affected daily Conversion Rates in respect of such conversion, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend
Date for such Spin-Off to, and including, the last Trading Day of such Observation Period. If such Spin-Off is not made or completed, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such Spin-Off had not
been declared. 
 (d) If any cash dividend or distribution is made to all or substantially all holders of the Common Stock, the
Conversion Rate shall be increased based on the following formula: 
  
 

 
 where, 
  

							
	
CR0
	  	 	=	  	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	
CR1
	  	 	=	  	  	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	
SP0
	  	 	=	  	  	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution;
			
	 C
	  	 	=	  	  	the amount in cash per share that the Company distributes to holders of the Common Stock.

 Any such increase pursuant to this Section 8.04(d) shall become effective
immediately after the open of business on the Ex-Dividend Date for such dividend or distribution. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder
of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares of the Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of
Common Stock equal to the Conversion Rate on the Ex-Dividend Date for such cash dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors
determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 

  
 32 

 (e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer
or exchange offer for the Common Stock, and the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the last date
on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall be increased based on the following formula: 
  

 
 where, 
  

							
	
CR0
	  	 	=	  	  	the Conversion Rate in effect immediately prior to the open of business on the Trading Day next succeeding the date such tender or exchange offer expires;
			
	
CR1
	  	 	=	  	  	the Conversion Rate in effect immediately after the open of business on the Trading Day next succeeding the date such tender or exchange offer expires;
			
	 AC
	  	 	=	  	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender or
exchange offer;
			
	
OS0
	  	 	=	  	  	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to the purchase of all shares of
Common Stock accepted for purchase or exchange in such tender offer or exchange offer);
			
	
OS1
	  	 	=	  	  	the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase of all shares of Common
Stock accepted for purchase or exchange in such tender or exchange offer); and
			
	
SP1
	  	 	=	  	  	the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the
date such tender or exchange offer expires.

 The adjustment to the Conversion Rate under this Section 8.04(e) shall be determined at the close of
business on the tenth Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires but shall be given effect immediately after the open of business on the Trading Day next
succeeding the date such tender or exchange offer expires; provided that in respect of any conversion within the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or
exchange offer, references in this Section 8.04(e) to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the date that such tender or exchange
offer expires to, and including, the Conversion Date for such conversion. If the Trading Day immediately following the date the tender or exchange offer expires is less than 10 Trading Days 

  
 33 

 
prior to, and including, the end of the Observation Period in respect of any conversion, references in this Section 8.04(e) to 10 Trading Days shall be deemed replaced, for purposes of
calculating the affected daily Conversion Rates in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day immediately following the date such tender or exchange offer expires to, and
including, the last Trading Day of such Observation Period. In the event that the Company is, or one of the Company’s Subsidiaries is, obligated to purchase shares of the Common Stock pursuant to any such tender offer or exchange offer, but the
Company is, or such Subsidiary is, permanently prevented by applicable law from effecting any such purchases, or any such purchases are rescinded, then the Conversion Rate shall be decreased to be the Conversion Rate which would then be in effect
had the increase with respect to such tender or exchange offer been made on the basis of the number of shares of the Common Stock actually purchased or exchanged pursuant to such tender offer or exchange offer. Except as set forth in the preceding
sentence, if the application of this Section 8.04(e) to any tender offer or exchange offer would result in a decrease in the Conversion Rate, no adjustment shall be made for such tender offer or exchange offer under this Section 8.04(e).

 (f) Notwithstanding this Section 8.04 or any other provision of this Supplemental Indenture or the Notes, if a
Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and a Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related Record Date would be treated as the record holder of the Common Stock as
of the related Conversion Date as described under Section 8.02(a)(iv) based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 8.04, the Conversion Rate
adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of a number of shares of Common Stock equal to the Conversion Rate on an
unadjusted basis, for each $1,000 principal amount of Notes, and participate in the related dividend, distribution or other event giving rise to such adjustment. 
 (g) Except as stated herein, the Company shall not adjust the Conversion Rate for the issuance of shares of the Common Stock or any securities convertible into or exchangeable for shares of the Common
Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable securities. 
 (h) In addition to
those adjustments required by Section 8.03 and clauses (a), (b), (c), (d) and (e) of this Section 8.04, and to the extent permitted by applicable law and the rules of the New York Stock Exchange and any other securities exchange
on which any of the Company’s securities are then listed, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase would be in
the Company’s best interest. In addition, the Company may (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in connection with a dividend or
distribution of shares (or rights to acquire shares) or similar event. Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall mail to the Holder of each Note at its last address appearing on
the Note Register a notice of such increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect. 

  
 34 

 (i) Notwithstanding anything to the contrary in this Article 8, the Conversion Rate
shall not be adjusted: 
 (i) upon the issuance of any shares of Common Stock pursuant to any present or future
plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan; 

(ii) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present
or future employee, director or consultant benefit plan or program or employee agreement or arrangement of or assumed by the Company or any of the Company’s Subsidiaries; 

(iii) upon the issuance of any shares of the Common Stock pursuant to any option, warrant, right or exercisable,
exchangeable or convertible security not described in clause (ii) of this subsection and outstanding as of the date the Notes were first issued, including the Company’s 3.00% Convertible Senior Notes due 2015; 

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

(v) for accrued and unpaid interest, if any. 
 (j) All calculations and other determinations under this Article 8 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000) of a share. No adjustment to the
Conversion Rate shall be required under this Section 8.04 unless such adjustment would require an increase or decrease of at least 1% of the Conversion Rate; provided that the Company shall carry forward any adjustments that are less
than 1% of the Conversion Rate that the Company elects not to make and make such carried-forward adjustments upon (1) each of the 40 days of any Observation Period with respect any conversion of the Notes (or, in the case of Physical
Settlement, any Conversion Date), (2) the occurrence of a Fundamental Change, (3) the Maturity Date and (4) such time as all adjustments that have not been made prior thereto would have the effect of adjusting the Conversion Rate by
at least 1%. 
 (k) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the
Trustee (and the Conversion Agent if not the Trustee) an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible
Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has
knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes
effective and shall mail such notice of such adjustment of the Conversion Rate to each Holder at its last address appearing on the Note Register provided for in this Indenture. Failure to deliver such notice shall not affect the legality or validity
of any such adjustment. 
 (l) For purposes of this Section 8.04, the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Company so long as the 

  
 35 

 
Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued
in lieu of fractions of shares of Common Stock. 
 Section 8.05 Adjustments of Prices. Whenever any provision of
this Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including an Observation Period and the period for determining
the Stock Price for purposes of a Make-Whole Fundamental Change), the Board of Directors shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to
the Conversion Rate where the Ex-Dividend Date of the event occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated. 

Section 8.06 Shares to Be Fully Paid. The Company shall provide at all times, free from preemptive rights, out of its
authorized but unissued shares or shares held in treasury, a number of shares of Common Stock equal to (a) 33.1564 subject to adjustment in the same manner as the Conversion Rate pursuant to Section 8.04 and subject to Section 8.12,
multiplied by (b)(i) the aggregate principal amount of Notes then outstanding, divided by (ii) $1,000, for the purpose of providing for conversion of the Notes from time to time as such Notes are presented for conversion.

 Section 8.07 Effect of Recapitalizations, Reclassifications and Changes of Common Stock. (a) In the case of:

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

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

in each case as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities or other property or assets
(including cash or any combination thereof) (any such event, a “Merger Event”), then, at and after the effective time of such Merger Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to
convert such principal amount of Notes into the kind and amount of shares of stock or other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the
Conversion Rate immediately prior to such Merger Event would have owned or been entitled to receive (the “Reference Property”, with each “unit of Reference Property” meaning the kind and amount of Reference Property
that a holder of one share of Common Stock is entitled to receive) upon such Merger Event and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the
Trustee a supplemental indenture providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however, 

  
 36 

 
that at and after the effective time of such Merger Event (A) the Company shall continue to have the right to determine the Settlement Method upon conversion of Notes in accordance with
Section 8.02 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 8.02 shall continue to be payable in cash, (II) any shares of Common Stock that the Company would have been required
to deliver upon conversion of the Notes in accordance with Section 8.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have been entitled to receive in such
Merger Event and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property. 
 If such
Merger Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then (i) the Reference Property into
which the Notes will be convertible or that will be used to calculate the Daily VWAP, as the case may be, shall be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively
make such an election, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. If the holders receive
only cash in such Merger Event, then for all conversions that occur after the effective date of such Merger Event (x) the consideration due upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount equal to the
Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 8.03), multiplied by the price per share of Common Stock in such Merger Event and (y) the Company shall satisfy the
Conversion Obligation by paying cash to converting Holders on the third Scheduled Trading Day immediately following the Conversion Date. The Company shall notify in writing all Holders, the Trustee and the Conversion Agent (if other than the
Trustee) of such weighted average as soon as practicable after such determination is made. 
 Such supplemental indenture
described in the second immediately preceding paragraph shall provide for adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in this Article 8. If, in the case of any Merger Event, the Reference
Property includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person other than the successor or purchasing corporation, as the case may be, in such Merger Event, then such supplemental
indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing,
including to the extent required by the Board of Directors and practicable the provisions providing for the purchase rights set forth in Article 9. 
 (b) In the event the Company shall execute a supplemental indenture pursuant to Section 8.07(a), the Company shall promptly file with the Trustee an Officer’s Certificate briefly stating the
reasons therefore, the kind or amount of cash, securities or property or asset that will comprise the Reference Property after any such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied
with, and shall promptly mail notice thereof to all Holders. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at its address appearing on the Note

  
 37 

 
Register provided for in this Indenture, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

 (c) The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 8.07.
None of the foregoing provisions shall affect any right that a holder of Notes may have to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, as set forth in Section 8.01 and
Section 8.02 prior to the effective date of such Merger Event. 
 (d) The above provisions of this Section shall similarly
apply to successive Merger Events. 
 Section 8.08 Certain Covenants. (a) The Company covenants that all shares
of Common Stock issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes (except as otherwise provided in Section 8.02(e)), liens and charges with respect to the issue thereof. 

(b) The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require
registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and interpretations of the Commission,
secure such registration or approval, as the case may be. 
 (c) The Company further covenants that if at any time the Common
Stock shall be listed on any national or regional securities exchange or automated quotation system the Company will list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, any Common
Stock issuable upon conversion of the Notes. 
 Section 8.09 Responsibility of Trustee. The Trustee and any other
Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the
Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and
any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion
of any Note; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of
Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this
Article 8. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into
pursuant to Section 8.07 relating either to the kind or amount of shares of stock or securities or property (including cash) 

  
 38 

 
receivable by Holders upon the conversion of their Notes after any event referred to in such Section 8.07 or to any adjustment to be made with respect thereto, but, subject to the provisions
of Section 9.01 of the Indenture may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in conclusively relying upon, the Officers’ Certificate (which the
Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by
Section 8.01(b) has occurred that makes the Notes eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent the notices referred to in Section 8.01(b) with respect to the
commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent may conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent immediately after the
occurrence of any such event or at such other times as shall be provided for in Section 8.01(b). 
 Section 8.10
Notice to Holders Prior to Certain Actions. In case of any: 
 (a) action by the Company or one of its
Subsidiaries that would require an adjustment in the Conversion Rate pursuant to Section 8.04 or Section 8.11; or 
 (b) Merger Event; or 
 (c) voluntary or involuntary dissolution,
liquidation or winding-up of the Company or any of its Subsidiaries; 
 then, in each case (unless notice of such event is otherwise required
pursuant to another provision of this Indenture), the Company shall cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be mailed to each Holder at its address appearing on the Security Register, as
promptly as possible but in any event at least 20 days prior to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its
Subsidiaries or, if a record is not to be taken, the date as of which the holders of Common Stock of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Merger
Event, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property
deliverable upon such Merger Event, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such action by the Company or one of its Subsidiaries, Merger Event,
dissolution, liquidation or winding-up. 
 Section 8.11 Stockholder Rights Plans. To the extent that the Company has
a rights plan in effect upon conversion of the Notes, each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued
upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time. If at the time of conversion, however, the rights have separated
from the shares of Common Stock in accordance with the provisions of the 

  
 39 

 
applicable stockholder rights plan so that the Holders would not be entitled to receive any rights in respect of Common Stock, if any, issuable upon conversion of the Notes, the Conversion Rate
shall be adjusted at the time of separation as if the Company distributed to all holders of Common Stock, shares of Capital Stock of the Company, evidences of indebtedness, assets, property, rights, options or warrants as provided in
Section 8.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights. 

Section 8.12 Limit on Issuance of Shares of Common Stock Upon Conversion. Notwithstanding anything to the contrary in this
Supplemental Indenture, if an event (other than a share split) occurs that results in an increase in the Conversion Rate that would potentially result in the issuance by the Company, upon conversion of the Notes, of 20% or more of the outstanding
Common Stock immediately prior to the issuance of Notes, the Company shall, at its option, either obtain stockholder approval of any issuance of Common Stock upon conversion of the Notes in excess such limitation or deliver cash in lieu of any
shares of Common Stock otherwise deliverable upon conversions in excess of such limitation based on the Daily VWAP of the Common Stock on each Trading Day of the relevant Observation Period in respect of which, in lieu of delivering shares of Common
Stock, the Company delivers cash pursuant to this Section 8.12. 
 ARTICLE 9 

PURCHASE OF NOTES AT OPTION OF
HOLDERS 
 Section 9.01 Purchase at Option of Holders Upon a Fundamental Change. (a) If a
Fundamental Change occurs at any time, then each Holder shall have the right, at such Holder’s option, to require the Company to purchase for cash all of such Holder’s Notes, or any portion of the principal amount thereof that is equal to
$1,000 or an integral multiple of $1,000, on the date (the “Fundamental Change Purchase Date”) specified by the Company, which shall not be less than 15 calendar days or more than 35 calendar days following the date of the
Fundamental Change Company Notice at a purchase price equal to 100% of the principal amount of such Notes or such portion of the principal amount of Notes, as applicable, plus accrued and unpaid interest, if any, thereon up to but excluding
the Fundamental Change Purchase Date (the “Fundamental Change Purchase Price”), unless the Fundamental Change Purchase Date occurs after a Regular Record Date and on or prior to the Interest Payment Date to which such Regular Record
Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid interest, if any, to Holders of record as of such Regular Record Date and the Fundamental Change Purchase Price shall be equal to 100% of the principal
amount of Notes or portions thereof, as applicable, to be purchased pursuant to this Article 9. 
 (b) Purchases of Notes
under this Section 9.01 shall be made, at the option of the Holder thereof, upon: 
 (i) delivery to the
Paying Agent by such Holder of a duly completed notice (the “Fundamental Change Purchase Notice”) in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in
compliance with the Depositary’s procedures for surrendering interests in Global Notes, 

  
 40 

 
if the Notes are Global Notes, in each case on or before the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date; and 

(ii) delivery of the Notes, if the Notes are Physical Notes, to the Paying Agent at any time after delivery of the
Fundamental Change Purchase Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Paying Agent, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of
the Depositary, in each case such delivery being a condition to receipt by the Holder of the Fundamental Change Purchase Price therefor. 
 The Fundamental Change Purchase Notice in respect of any Notes to be purchased shall state: 
 (i) in the case of Physical Notes, the certificate numbers of the Notes to be delivered for purchase; 
 (ii) the portion of the principal amount of Notes to be purchased, which must be $1,000 or an integral multiple thereof; and 

(iii) that the Notes are to be purchased by the Company pursuant to this Section 9.01; 

provided, however, that if the Notes are Global Notes, the Fundamental Change Purchase Notice must comply with appropriate Depositary
procedures. 
 Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change
Purchase Notice contemplated by this Section 9.01 shall have the right to withdraw, in whole or in part, such Fundamental Change Purchase Notice at any time prior to the close of business on the Business Day immediately preceding the
Fundamental Change Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 9.02. 
 The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Purchase Notice or written notice of withdrawal thereof. 

(c) On or before the 10th calendar day after the occurrence of the effective date of a Fundamental Change, the Company shall provide to
all Holders of Notes and the Trustee and the Paying Agent (if other than the Trustee) a notice (the “Fundamental Change Company Notice”) of the occurrence of the effective date of such Fundamental Change and of the purchase right at
the option of the Holders arising as a result thereof. Such notice shall be by first class mail or, in the case of Global Notes, in accordance with the applicable procedures of the Depositary. Simultaneously with providing such notice, the Company
shall issue a press release containing the information set forth in such Fundamental Change Company Notice or publish such information on the Company’s website or through such other public medium as the Company may use at that time. Each
Fundamental Change Company Notice shall specify: 
 (i) the events causing the Fundamental Change; 

  
 41 

 (ii) the effective date of the Fundamental Change; 

(iii) the last date on which a Holder may exercise the purchase right pursuant to this Article 9; 

(iv) the Fundamental Change Purchase Price; 

(v) the Fundamental Change Purchase Date; 

(vi) the name and address of the Paying Agent and the Conversion Agent, if applicable; 

(vii) the Conversion Rate and, if applicable, any adjustments to the Conversion Rate; 

(viii) if applicable, that the Notes with respect to which a Fundamental Change Purchase Notice has been delivered by a
Holder may be converted only if the Holder withdraws the Fundamental Change Purchase Notice in accordance with the terms of this Indenture; and 
 (ix) the procedures that Holders must follow to require the Company to purchase their Notes. 
 No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ purchase rights or affect the validity of the proceedings for the purchase of the Notes pursuant
to this Section 9.01. 
 At the Company’s written request, the Trustee shall give such notice in the Company’s
name and at the Company’s expense; provided, however, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company. 

(d) Notwithstanding the foregoing, no Notes may be purchased by the Company on any date at the option of the Holders upon a Fundamental
Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental
Change Purchase Price with respect to such Notes). The Paying Agent shall promptly return to the respective Holders thereof any Physical Notes held by it during the acceleration of the Notes and shall deem to be cancelled any instructions for
book-entry transfer of the Notes to the Paying Agent in compliance with the procedures of the Depositary (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Purchase Price with
respect to such Notes), in which case, upon such return or cancellation, as the case may be, the Fundamental Change Purchase Notice with respect thereto shall be deemed to have been withdrawn. 

Section 9.02 Withdrawal of Fundamental Change Purchase Notice. (a) A Fundamental Change Purchase Notice may be withdrawn
(in whole or in part) by means of a written notice of withdrawal delivered to the Paying Agent in accordance with this Section 9.02 

  
 42 

 
at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date, specifying: 

(i) the principal amount of the Notes with respect to which such notice of withdrawal is being submitted, 

(ii) if such Notes are Physical Notes, the certificate numbers of such Notes, and 

(iii) the principal amount, if any, of such Notes that remains subject to the original Fundamental Change Purchase Notice,
which portion must be in principal amounts of $1,000 or an integral multiple of $1,000; 
 provided, however, that if the Notes
are Global Notes, the notice must comply with appropriate procedures of the Depositary. 
 Section 9.03 Deposit of
Fundamental Change Purchase Price. (a) The Company shall deposit with the Trustee (or other Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in
Section 6.03 of the Indenture) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Purchase Date an amount of money sufficient to purchase all of the Notes to be purchased at the appropriate Fundamental Change Purchase
Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for purchase (and not withdrawn prior to the close of business on the Business Day immediately preceding
the Fundamental Change Purchase Date) will be made on the later of (i) the Fundamental Change Purchase Date with respect to such Note (provided the Holder has satisfied the conditions in Section 9.01) and (ii) the time of
book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by Section 9.01 by mailing checks for the amount payable to the Holders of such Notes
entitled thereto as they shall appear in the Note Register, provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee
shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change Purchase Price. 
 (b) If by 11:00 a.m. New York City time, on the Fundamental Change Purchase Date, the Trustee (or other Paying Agent appointed by the Company) holds money sufficient to make payment on all the Notes
or portions thereof that are to be purchased on such Fundamental Change Purchase Date, then (i) such Notes shall cease to be outstanding, (ii) interest shall 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) and (iii) all other rights of the Holders of such Notes will terminate (other than the right to receive the Fundamental Change Purchase Price upon delivery of the
Notes). 
 (c) Upon surrender of a Note that is to be purchased in part pursuant to Section 9.01, the Company shall execute
and the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the non-purchased portion of the Note surrendered. 

  
 43 

 Section 9.04 Covenant to Comply with Applicable Laws Upon Purchase of Notes. In
connection with any purchase offer pursuant to Section 9.01, the Company shall, if required thereby: 
 (a)
comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable; 
 (b) file a Schedule TO or any successor or similar schedule; and 
 (c) otherwise comply with all federal and state securities laws in connection with any offer by the Company to purchase the Notes; 
 in each case, so as to permit the rights and obligations under this Article 9 to be exercised in the time and in the manner specified in this Article 9. 

ARTICLE 10 

SUBSIDIARY GUARANTEES 
 Section 10.01 Subsidiary Guarantees. Each Subsidiary listed on the signature page hereto shall constitute a Subsidiary Guarantor of the Notes, and the Subsidiary Guarantee of such Subsidiary
Guarantor shall have the terms set forth in Article XIII of the Base Indenture as modified solely for purposes of the Notes as set forth in this Article 10. 
 Section 10.02 Future Subsidiary Guarantors. If after the Issue Date, any Subsidiary of the Company incurs or guarantees any Obligations under the Credit Facility prior to the conversion,
repurchase or maturity of the Notes, the Company shall concurrently cause such Subsidiary to (A) execute and deliver to the Trustee a supplemental indenture in a form reasonably satisfactory to the Trustee pursuant to which such Subsidiary
shall fully and unconditionally guarantee all the Company’s Obligations under the Notes and the Indenture in accordance with Article XIII of the Base Indenture as modified solely for purposes of the Notes as set forth in this Article 10 and
(B) deliver to the Trustee an Opinion of Counsel to the effect that (i) such supplemental indenture and Subsidiary Guarantee has been duly executed and authorized and (ii) such supplemental indenture and Subsidiary Guarantee
constitutes a valid, binding and enforceable obligation of such Subsidiary Guarantor, except insofar as enforcement thereof may be limited by bankruptcy, insolvency or similar laws (including, without limitation, all laws relating to fraudulent
transfers) and except insofar as enforcement thereof is subject to general principles of equity. Any such Subsidiary Guarantee shall be pari passu in right of payment with the obligations of such Subsidiary under the Credit Facility. 

Section 10.03 Release of Subsidiary Guarantors. Each Subsidiary Guarantee shall be automatically and unconditionally released
and discharged and the Holders of the Notes will be deemed to have consented to such release without any action on the part of the Trustee or any holder of the Notes (a) upon such Subsidiary Guarantor ceasing to be an obligor under the Credit
Facility; or (b) upon the sale or other disposition (including by way of consolidation or merger), in one transaction or a series of related transactions, of a majority of the total voting stock of such Subsidiary Guarantor, provided
that in the case of this clause (b), after giving effect to such transaction, such entity is (1) no longer a Subsidiary of the Company and (2) no longer 

  
 44 

 
an obligor under the Credit Facility. Upon the satisfaction of any such condition to the release of such Subsidiary Guarantee, upon Company Request, the Trustee shall execute and deliver any
documents, instructions or instruments necessary to evidence such release. 
 ARTICLE 11

CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. EACH OF THE COMPANY, THE SUBSIDIARY GUARANTORS AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY
LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTION CONTEMPLATED HEREBY.

Rate of the Notes. The Company shall make all of these calculations in good faith and, absent manifest error, the Company’s calculations shall be final and binding on Holders of Notes. The Company shall provide a schedule of its calculations to
each of the Trustee and the Conversion Agent, and each of the Trustee and Conversion Agent is entitled to rely conclusively upon the accuracy of the Company’s calculations without independent verification. The Trustee will forward the
Company’s calculations to any Holder of Notes upon the written request of that Holder at the sole cost and expense of the Company.

 FORM OF REVERSE OF NOTE 

RTI INTERNATIONAL METALS, INC. 
 1.625% Convertible Senior Notes due 2019 
 This Note is one of a duly authorized
issue of Notes of the Company, designated as its 1.625% Convertible Senior Notes due 2019 (the “Notes”), limited to the aggregate principal amount of $402,500,000 all issued or to be issued under and pursuant to an Indenture dated as of
December 14, 2010 (the “Base Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A. (the “Trustee”) as supplemented by a Supplemental Indenture dated as of April 17, 2013 (the
“Supplemental Indenture” and together with the Base Indenture, the “Indenture”) among the Company, the Subsidiary Guarantors named therein and the Trustee, to which Indenture and all indentures supplemental thereto reference is
hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company, the Subsidiary Guarantors and the Holders of the Notes. Additional Notes may be issued in an unlimited
aggregate principal amount, subject to certain conditions specified in the Indenture. 
 In case an Event of Default, as defined
in the Indenture, shall have occurred and be continuing, the principal of, and interest on, all Notes may be declared, by either the Trustee or Holders of at least 25% of the aggregate principal amount of Notes then outstanding, and upon said
declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture. 
 Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Purchase Price on the Fundamental Change Purchase Date and in
respect of the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent to collect such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at
the time of payment is legal tender for payment of public and private debts. 
 The Indenture contains provisions permitting the
Company, any Subsidiary Guarantor and the Trustee in certain circumstances, without the consent of the Holders of the Notes, and in certain other circumstances, with the consent of the Holders of not less than a majority of the aggregate principal
amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to
certain exceptions, the Holders of a majority of the 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 under the Indenture and its
consequences. 
 No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair
the obligation of the Company, which is absolute and unconditional, to pay the principal (including the Fundamental Change Purchase Price, if applicable) of and accrued and unpaid interest on this Note at the place, at the respective times, at the
rate and in the lawful money herein prescribed. 

  
 A-5

 The Notes are issuable in registered form without coupons in denominations of $1,000
principal amount and integral multiples thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal
amount of Notes of other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith as
a result of the name of the Holder of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange. 

The Notes are not subject to redemption through the operation of any sinking fund or otherwise. 

Upon the occurrence of a Fundamental Change, the Holder has the right, at such Holder’s option, to require the Company to purchase
for cash all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Purchase Date at a price equal to the Fundamental Change Purchase Price. 

Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, during certain periods and upon the
occurrence of certain conditions specified in the Indenture, prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple
thereof, into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture. 

Terms used in this Note and defined in the Indenture are used herein as therein defined.

 Exhibit 4.1 
 FIFTH SUPPLEMENTAL INDENTURE 
 FIFTH SUPPLEMENTAL
INDENTURE (this “Supplemental Indenture”), dated as of March 20, 2013, between Galileo International Technology, LLC (the “Guaranteeing Subsidiary”) and Computershare Trust Company, N.A. (as
successor of The Bank of Nova Scotia Trust Company of New York), as trustee under the Indenture referred to below (the “Trustee”). 
 W I T N E S S E T H 
 WHEREAS, Travelport LLC, (f/k/a TDS
Investor Corporation), a Delaware limited liability company (the “Issuer”), has heretofore executed and delivered to the Trustee an indenture, dated as of August 23, 2006, as supplemented by Supplemental Indenture No. 1
thereto on January 11, 2007 and as further supplemented by Supplemental Indenture No. 2 thereto on March 13, 2007, Supplemental Indenture No. 3 thereto on September 19, 2007 and Supplemental Indenture No. 4 thereto on
December 11, 2012 (as so supplemented, the “Indenture”), providing for the issuance of $150,000,000 aggregate principal amount of Senior Dollar Floating Rate Notes due 2014, €235,000,000 aggregate principal amount of
Senior Euro Floating Rate Notes due 2014 and $450,000,000 aggregate principal amount of 9 7/8% Senior Dollar Fixed Rate Notes due 2014 (together, the “Notes”); 

WHEREAS, pursuant to Section 9.01 of the Indenture, which does not require the consent of the Holders, the Guaranteeing Subsidiary
desires to enter into this Supplemental Indenture pursuant to which the Guaranteeing Subsidiary, jointly and severally with all Guarantors named in the Indenture (which for the avoidance of doubt shall include the guaranteeing subsidiaries party to
the supplemental indentures thereto), agrees to pay and shall fully and unconditionally guarantee all of the Issuer’s obligations under the Indenture and all of the Notes pursuant to the Indenture on the terms and conditions set forth herein
(the “Guarantee”); and 
 WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to
execute and deliver this Supplemental Indenture. 
 NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt of which is hereby acknowledged, the parties mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows: 

(1) Capitalized Terms. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture.

 (2) Agreement to Guarantee. The Guaranteeing Subsidiary hereby agrees as follows: 

(a) Along with all Guarantors named in the Indenture, to jointly and unconditionally unconditionally guarantee to each
Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, the Notes or the obligations of the Issuer hereunder or thereunder,
that: 
 (i) the principal of and interest, premium and Additional Interest, if any, on the Notes will be
promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Issuer to the Holders or the
Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 
 (ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that the same will be promptly paid in full when due or performed in accordance with the terms of
the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors and the Guaranteeing Subsidiary shall be
jointly and severally obligated to pay the same immediately. This is a guarantee of payment and not a guarantee of collection. 

 (b) The obligations hereunder shall be unconditional, irrespective of the
validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment
against the Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. 

(c) The following are hereby waived: diligence, presentment, demand of payment, filing of claims with a court in the event
of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands whatsoever. 
 (d) This Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes, the Indenture and this Supplemental Indenture, and the Guaranteeing Subsidiary accepts
all obligations of a Guarantor under the Indenture. 
 (e) If any Holder or the Trustee is required by any court
or otherwise to return to the Issuer, the Guarantors (including the Guaranteeing Subsidiary), or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuer or the Guarantors, any amount paid either to the
Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. 
 (f) The Guaranteeing Subsidiary shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations
guaranteed hereby. 
 (g) As between the Guaranteeing Subsidiary, on the one hand, and the Holders and the
Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 of the Indenture for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any 

  
 2 

 
declaration of acceleration of such obligations as provided in Article 6 of the Indenture, such obligations (whether or not due and payable) shall forthwith become due and payable by the
Guaranteeing Subsidiary for the purpose of this Guarantee. 
 (h) The Guaranteeing Subsidiary shall have the
right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under this Guarantee. 
 (i) Pursuant to Section 10.02 of the Indenture, after giving effect to all other contingent and fixed liabilities that are relevant under any applicable Bankruptcy or fraudulent conveyance laws, and
after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under Article 10 of the Indenture, this new Guarantee
shall be limited to the maximum amount permissible such that the obligations of the Guaranteeing Subsidiary under this Guarantee will not constitute a fraudulent transfer or conveyance. 

(j) This Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or
against the Issuer for liquidation, reorganization, should the Issuer become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Issuer’s assets, and
shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be
restored or returned by any obligee on the Notes and Guarantee, whether as a “voidable preference”, “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment or
any part thereof, is rescinded, reduced, restored or returned, the Note shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned. 

(k) In case any provision of this Guarantee shall be invalid, illegal or un-enforceable, the validity, legality, and
enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
 (l) This
Guarantee shall be a general unsecured senior obligation of the Guaranteeing Subsidiary, ranking pari passu with any other future Senior Indebtedness of the Guaranteeing Subsidiary, if any. 

(m) Each payment to be made by the Guaranteeing Subsidiary in respect of this Guarantee shall be made without set-off,
counterclaim, reduction or diminution of any kind or nature. 
 (3) Execution and Delivery. The Guaranteeing Subsidiary agrees
that the Guarantee shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes.

one or more related transactions, to any Person unless:

Subsidiary or such Person, as the case may be, being herein called the “Successor Person”); 
 (B) the
Successor Person, if other than the Guaranteeing Subsidiary, expressly assumes all the obligations of the Guaranteeing Subsidiary under the Indenture and the Guaranteeing Subsidiary’s related Guarantee pursuant to supplemental indentures or
other documents or instruments in form reasonably satisfactory to the Trustee; 
 (C) immediately after such
transaction, no Default exists; and 
 (D) the Issuer shall have delivered to the Trustee an Officer’s

(b) Subject to certain limitations described in the Indenture, the Successor Person will succeed to, and be substituted
for, the Guaranteeing Subsidiary under the Indenture and the Guaranteeing Subsidiary’s Guarantee. Notwithstanding the foregoing, the Guaranteeing Subsidiary may merge into or transfer all or part of its properties and assets to another
Guarantor or the Issuer. 
 (5) Releases. 
 The Guarantee of the Guaranteeing Subsidiary shall be automatically and unconditionally released and discharged, and no further action by the Guaranteeing Subsidiary, the Issuer or the Trustee is required
for the release of the Guaranteeing Subsidiary’s Guarantee, upon: 
 (1) (A) any sale, exchange or transfer
(by merger or otherwise) of the Capital Stock of the Guaranteeing Subsidiary (including any sale, exchange or transfer), after which the Guaranteeing Subsidiary is no longer a Restricted Subsidiary or all or substantially all the assets of the
Guaranteeing Subsidiary which sale, exchange or transfer is made in compliance with the applicable provisions of the Indenture;

(D) the Issuer exercising its Legal Defeasance option or Covenant Defeasance option in accordance with Article 8 of the
Indenture or the Issuer’s obligations under the Indenture being discharged in accordance with the terms of the Indenture; and 
 (2) the Guaranteeing Subsidiary delivering to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for in the Indenture relating to such
transaction have been complied with. 
 (6) No Recourse Against Others. No director, officer, employee, incorporator or
stockholder of the Guaranteeing Subsidiary shall have any liability for any obligations of the Issuer or the Guarantors (including the Guaranteeing Subsidiary) under the Notes, any Guarantees, the Indenture or this Supplemental Indenture or for any
claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting Notes waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then due and payable by the Issuer under the Indenture or the Notes shall have been paid in full.
