have notations, legends or endorsements required by law, exchange rule, Applicable Procedures or usage. The Company shall provide any such notations, legends or endorsements to the Trustee in writing. Each Security shall be dated the date of its
authentication. 
  

 5 

 The terms and provisions contained in the Securities shall constitute, and are hereby expressly made, a
part of the Indenture and the Company and the Trustee, by their execution and delivery of this First Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby; provided, however, to the extent
permitted by applicable law, if any provision of any Security conflicts with the express provisions of this First Supplemental Indenture, the provisions of this First Supplemental Indenture shall govern and be controlling. 
 (b) Global Securities. All of the Securities shall be issued initially in the form of one or more Global Securities, which shall be deposited on
behalf of the purchasers of the Securities represented thereby with the Securities Custodian, as custodian for the depositary, The Depository Trust Company (such depositary, or any successor thereto, being hereinafter referred to as the
“Depositary”), and registered in the name of its nominee, Cede & Co., or as otherwise instructed by the Depositary, duly executed by the Company and authenticated by the Trustee as hereinafter provided. The aggregate
principal amount of the Global Securities may from time to time be increased or decreased by adjustments made on the records of the Securities Custodian and the Depositary as hereinafter provided, subject in each case to compliance with the
Applicable Procedures and the provisions of this First Supplemental Indenture. 
 (c) Global Securities In General. Each Global
Security shall represent such of the outstanding Securities as shall be specified therein and each shall provide that it shall represent the aggregate amount of outstanding Securities from time to time endorsed thereon and that the aggregate amount
of outstanding Securities represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, purchases or conversions of such Securities, in each case in accordance with this First Supplemental Indenture. Any
adjustment of the aggregate principal amount of a Global Security to reflect the amount of any increase or decrease in the amount of outstanding Securities represented thereby shall be made by the Trustee in accordance with instructions given by the
Holder thereof as required by Section 2.09 hereof, or otherwise in accordance with the Indenture, and shall be made on the records of the Trustee and the Depositary. 
 The Company shall issue and the Trustee shall, upon receipt of an Order from the Company, authenticate and deliver in accordance with Section 2.02 hereof, initially one or more Global Securities that
(i) shall be registered in the name of Cede & Co. or as otherwise instructed by the Depositary, (ii) shall be delivered by the Trustee to the Depositary or to the Securities Custodian pursuant to the Depositary’s instructions
and (iii) shall bear legends required for Global Securities as set forth in Exhibit A hereto. 
 (d) Certificated
Securities. Certificated Securities shall be issued only under the circumstances provided in Section 2.09(a)(i) hereof. 
 Section 2.02. Execution and Authentication. (a) A duly authorized Officer of the Company shall sign the Securities for the Company by manual or facsimile signature. 
 (b) If an Officer of the Company whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the
Security shall be valid nevertheless. 
 (c) A Security shall not be valid until an authorized signatory of the Trustee manually signs the
certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under the Indenture. 
 (d) The Trustee shall initially authenticate and make available for delivery Securities for original issue in the aggregate principal amount of $74,750,000 upon receipt of an Order of the Company in accordance with
Section 3.3 of the Original Indenture. The Company may, without the consent of the Holders, re-open the Securities and issue additional Securities (the “Additional Securities”) with the same terms (including placing a portion
of the proceeds thereof in the Escrow Account to secure any interest payments due on or before April 

  

 6 

 
15, 2011) and with the same CUSIP number as the Securities in an unlimited aggregate principal amount; provided, however that no such Additional
Securities may be issued unless fungible with the Securities offered hereby for U.S. federal income tax purposes. The Trustee shall authenticate Additional Securities thereafter in unlimited aggregate principal amount (so long as permitted by the
terms of the Indenture) for original issue upon an Order of the Company in aggregate principal amount as specified in such order (except as provided in Section 2.06 hereof). Each such Order of the Company shall specify the amount of Securities
to be authenticated and the date on which the Securities are to be authenticated. Such Additional Securities shall have identical terms to the Initial Securities except for issuance dates and prices and with respect to interest accruing prior to
their date of issuance, and will constitute the same series as the Initial Securities for all purposes hereunder, including, without limitation, waivers, amendments and offers to purchase. 
 (e) The Trustee shall act as the initial authenticating agent. Thereafter, the Trustee may appoint an authenticating agent acceptable to the Company to
authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this First Supplemental Indenture to authentication by the Trustee includes authentication by such agent. An
authenticating agent shall have the same rights as an Agent to deal with the Company or an Affiliate of the Company. 
 The Securities shall
be issuable only in registered form without coupons and only in denominations of $1,000 principal amount and any integral multiple thereof. 
 Section 2.03. Registrar, Paying Agent and Conversion Agent. The Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (“Registrar”), an office
or agency in the United States where Securities may be presented for purchase or payment (“Paying Agent”), an office or agency where Securities may be presented for conversion (“Conversion Agent”), and an office or
agency where notices and demands to or upon the Company in respect of the Securities and the Indenture may be served. The Registrar shall keep a register of the Securities (“Register”) and of their transfer and exchange. 

The Company may have one or more co-registrars, one or more additional paying agents, and one or more additional conversion agents. The term
“Registrar” includes any co-registrar, including any named pursuant to Section 10.02 of the Original Indenture. The term “Paying Agent” includes any additional paying agent, including any named pursuant to Section 10.02
of the Original Indenture. The term “Conversion Agent” includes any additional conversion agent, including any named pursuant to Section 10.02 of the Original Indenture. 
 The Company shall enter into an appropriate agency agreement with any Agent not a party to this First Supplemental Indenture. The agreement shall
implement the provisions of the Indenture that relate to such Agent. The Company shall notify the Trustee of the name and address of any Agent not a party to this First Supplemental Indenture. If the Company fails to maintain a Registrar, Paying
Agent or Conversion Agent or agent for service of notices and demands in any place required by the Indenture, or fails to give the foregoing notice, the Trustee shall act as such. The Company or any Affiliate of the Company may act as Paying Agent.

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

 Section 2.04. Paying Agent to Hold Money and Securities in Trust. On or prior to 11:00 a.m., New York City time, on
each due date of payments of Cash or shares of Common Stock in respect of the Securities, as applicable and as provided herein, the Company shall deposit with the Paying Agent Cash (in immediately available funds if deposited on the due date) or
with the Conversion Agent such number of shares of Common Stock, Cash or other consideration sufficient to make such payments or deliveries when so becoming due. The Company shall require each Paying Agent or Conversion Agent, as applicable (other
than 

  

 7 

 
the Trustee), to agree in writing that such Agent shall hold in trust for the benefit of Securityholders or the Trustee all Cash, Common Stock or other
consideration, as applicable, held by such Agent for the making of payments or deliveries in respect of the Securities and shall notify the Trustee in writing of any default by the Company in making any such payment or delivery. If the Company or an
Affiliate of the Company acts as Paying Agent or Conversion Agent, as applicable, it shall segregate the Cash, Common Stock and other consideration, as applicable, held by it as Paying Agent or Conversion Agent, as applicable, and hold it as a
separate trust fund. 
 The Company at any time may require a Paying Agent or Conversion Agent, as applicable, to pay all Cash, Common Stock
or other consideration, as applicable, held by it to the Trustee, and the Trustee may at any time during the continuance of any Default, upon written request to the Paying Agent or the Conversion Agent, as applicable, require such Paying Agent or
Conversion Agent, as applicable, to pay forthwith to the Trustee all Cash, Common Stock or other consideration, as applicable, so held in trust by such Paying Agent or Conversion Agent. Upon doing so, the Paying Agent or the Conversion Agent, as
applicable, shall have no further liability for such Cash, Common Stock or other consideration, as applicable. 
 Section 2.05.
Transfer and Exchange. (a) Subject to compliance with any applicable additional requirements contained in Section 2.09 hereof, when a Security is presented to a Registrar with a request to register a transfer thereof or to exchange
such Security for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested; provided, however, that every Security presented or surrendered
for registration of transfer or exchange shall, if such Security is a Certificated Security, be duly endorsed or accompanied by an assignment form, in the form included in Exhibit A attached hereto and, if applicable, a transfer certificate, in
the form included in Exhibit A attached hereto, and in form reasonably satisfactory to the Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. To permit registration of transfers and exchanges, upon
surrender of any Security for registration of transfer or exchange at an office or agency maintained pursuant to Section 2.03 hereof, the Company shall execute and the Trustee shall, upon receipt of an Order of the Company, authenticate
Securities of a like aggregate principal amount at the Registrar’s request. Any exchange or transfer shall be without charge, except that the Company or the Registrar may require payment of a sum sufficient to cover any tax, assessment or other
governmental charge that may be imposed in relation thereto, other than exchanges pursuant to Section 3.4 of the Original Indenture or Section 8.04, Article 3 or Article 4 of this First Supplemental Indenture, in each case, not involving
any transfer. 
 Neither the Company, any Registrar nor the Trustee shall be required to exchange or register a transfer of any Securities or
portions thereof in respect of which a Fundamental Change Repurchase Notice has been delivered and not validly withdrawn by the Holder thereof (except, in the case of the purchase of a Security in part, the portion thereof not to be purchased).

 All Securities issued upon any transfer or exchange of Securities shall be valid obligations of the Company, evidencing the same debt and
entitled to the same benefits under this Indenture as the Securities surrendered upon such transfer or exchange. 
 (b) Any Registrar
appointed pursuant to Section 2.03 hereof or Section 10.2 of the Original Indenture shall provide to the Trustee such information as the Trustee may reasonably request in connection with the delivery by such Registrar of Securities upon
transfer or exchange of Securities. 
 The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with
any restrictions on transfer imposed under the Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Agent Members or other beneficial owners of interests in any
Global Security) other than to require delivery of such opinions of counsel, certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by 

  

 8 

 
the terms of, the Indenture (including if so requested by the Company exercising a right to require the delivery of such items), and to examine the same to
determine substantial compliance as to form with the express requirements hereof. 
 Any Holder of a Global Security shall, by acceptance of
such Global Security, agree that transfers of beneficial interests in such Global Security may be effected only through a book-entry system maintained by the Depositary (or its agent), and that ownership of a beneficial interest in a Global Security
shall be required to be reflected in a book-entry system. 
 Section 2.06. Replacement Securities. If (a) any mutilated
Security is surrendered to the Company, a Registrar or the Trustee, or (b) the Company, the Registrar and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and, in either case, there is
delivered to the Company, the Registrar and the Trustee such security or indemnity as shall be reasonably required by them to save each of them harmless, then, in the absence of notice to the Company, such Registrar or the Trustee that such Security
has been acquired by a bona fide or protected purchaser, the Company shall issue, and the Trustee shall, upon receipt of an Order of the Company (which the Company agrees to deliver promptly), authenticate and deliver, in exchange for any such
mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount, bearing a number not contemporaneously outstanding. 
 In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, or purchased by the Company pursuant to
Article 3 hereof, the Company in its discretion may, instead of issuing a new Security, pay or purchase such Security, as the case may be, in accordance herewith. 
 Upon the issuance of any new Securities under this Section 2.06, the Company may require the payment of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in relation
thereto and any other reasonable expenses (including the reasonable fees and expenses of the Trustee or the Registrar) in connection therewith. 
 Every new Security issued pursuant to this Section 2.06 in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of the Indenture equally and proportionately with any and all other Securities duly issued and outstanding hereunder. 
 The provisions of this Section 2.06 are (to the extent lawful) exclusive and shall preclude (to the extent lawful) all other rights and remedies
with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 
 Section 2.07. Outstanding
Securities. Securities outstanding at any time are all Securities authenticated by the Trustee, except for those canceled by it, those paid or repurchased pursuant to Section 2.06 hereof, those delivered to it for cancellation and those
described in this Section 2.07 as not outstanding. 
 If a Security is replaced pursuant to Section 2.06 hereof (other than a
mutilated Security surrendered for replacement), it ceases to be outstanding unless the Trustee receives, subsequent to the new Security’s authentication, proof satisfactory to the Company that the replaced Security is held by a bona fide or
protected purchaser. A mutilated Security ceases to be outstanding upon surrender and replacement thereof pursuant to Section 2.06 hereof. 
 If the Paying Agent holds, in accordance with the terms of the Indenture, at 11:00 a.m., New York City time, on the Maturity Date or on a Fundamental Change Repurchase Date, as the case may be, Cash sufficient to pay all Initial
Securities and all Additional Securities then payable, then on and after such Maturity Date or 

  

 9 

 
Fundamental Change Repurchase Date, as the case may be, such Securities shall cease to be outstanding and interest on such Securities shall cease to accrue.

 If a Security is converted in accordance with Article 4 hereof, then on the Conversion Date, such Security shall cease to be outstanding
and interest on such Security shall cease to accrue, unless there shall be a default in the delivery of the consideration payable hereunder upon such conversion. 
 Subject to the restrictions contained in Section 2.08 hereof, a Security does not cease to be outstanding solely because the Company or an Affiliate of the Company holds the Security. 
 Section 2.08. Treasury Securities. In determining whether the Holders of the required principal amount of Securities have given or concurred
in any notice, request, demand, authorization, direction, waiver or consent, Securities owned by the Company or any other obligor on the Securities or by any Affiliate of the Company or of such other obligor shall be disregarded and deemed not to be
outstanding for such purposes, except that, for purposes of determining whether the Trustee shall be protected in relying on any such notice, request, demand, authorization, direction, waiver or consent, only Securities which a Trust Officer
actually knows are so owned shall be so disregarded. Securities so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to
the Securities and that the pledgee is not, and is not acting on the behalf of, the Company or any other obligor on the Securities or any Affiliate of the Company or of such other obligor. If requested by the Trustee, the Company agrees to notify
the Trustee in writing of the existence of any such Treasury Securities or Securities owned by the Company, any other obligor on the Securities, or, to the knowledge of the Company, any Affiliate of the Company. 
 Section 2.09. Legend; Additional Transfer and Exchange Requirements. (a) Transfer and Exchange of Global Securities. 
 (i) Certificated Securities shall be issued in exchange for interests in the Global Securities only (x) if the Depositary notifies the Company that
it is unwilling or unable to continue as Depositary for the Global Securities or if it at any time ceases to be a “clearing agency” registered under the Exchange Act, if so required by applicable law or regulation, and a successor
Depositary is not appointed by the Company within 90 days of such notice, (y) the Company delivers to the Trustee and the Registrar an Officers’ Certificate stating that such Global Security shall be so exchangeable or (z) if an Event
of Default has occurred and is continuing, in each case in accordance with the Applicable Procedures. In any such case, the Company shall execute, and the Trustee shall, upon receipt of an Order of the Company (which the Company agrees to deliver
promptly), authenticate and deliver Certificated Securities in an aggregate principal amount equal to the principal amount of such Global Securities in exchange therefor. Certificated Securities issued in exchange for beneficial interests in Global
Securities shall be registered in such names and shall be in such authorized denominations as the Depositary, pursuant to instructions from its Agent Members or otherwise in accordance with the Applicable Procedures, shall instruct the Trustee. The
Trustee shall deliver or cause to be delivered such Certificated Securities to the Persons in whose name such Securities are so registered. Such exchange shall be effected in accordance with the Applicable Procedures. In the event that the
Certificated Securities are not issued to each such beneficial owner promptly after the Registrar has received a request from the Depositary to issue such Certificated Securities, the Company expressly acknowledges, with respect to the right of any
Holder to pursue a remedy pursuant to Section 7.05 or 7.06 hereof, the right of any beneficial holder of Securities to pursue such remedy pursuant to the terms of such sections with respect to the portion of the Global Security that represents
such beneficial owner’s Securities as if such Certificated Securities had been issued. 
 (ii) Notwithstanding any other provisions of
the Indenture other than the provisions set forth in Section 2.09(a)(i) hereof, a Global Security may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or
another nominee of the 

  

 10 

 
Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. 
 (b) Transfer and Exchange of Certificated Securities. In the event that Certificated Securities are issued in exchange for beneficial interests in
Global Securities in accordance with Section 2.09(a)(i) hereof, and, on or after such event, Certificated Securities are presented by a Holder to the Registrar with a request: 
 (x) to register the transfer of the Certificated Securities to a person who shall take delivery thereof in the form of Certificated
Securities only; or 
 (y) to exchange such Certificated Securities for an equal principal amount of Certificated Securities
of other authorized denominations, 
 such Registrar shall register the transfer or make the exchange as requested; provided, however, that the
Certificated Securities presented or surrendered for register of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in accordance with the proviso to the first sentence of Section 2.05(a) hereof.

 (c) Transfers of Certificated Securities for Beneficial Interests in Global Securities. In the event that Certificated Securities
are issued in exchange for beneficial interests in Global Securities and, thereafter, the events or conditions specified in Section 2.09(a)(i) hereof which required such exchange shall cease to exist, the Company shall mail notice to the
Trustee and to the Holders (i) stating that Holders may exchange Certificated Securities for interests in Global Securities by complying with the procedures set forth in the Indenture and (ii) briefly describing such procedures and the
events or circumstances requiring that such notice be given. Thereafter, if Certificated Securities are presented by a Holder to a Registrar with a request: 
 (x) to register the transfer of such Certificated Securities to a Person who will take delivery thereof in the form of a beneficial
interest in a Global Security; or 
 (y) to exchange such Certificated Securities for an equal principal amount of beneficial
interests in a Global Security, which beneficial interests will be owned by the Holder transferring such Certificated Securities, 
 the Registrar shall
register the transfer or make the exchange as requested by canceling such Certificated Security and causing the aggregate principal amount of the applicable Global Security to be increased accordingly and, if no such Global Security is then
outstanding, the Company shall issue and the Trustee shall, upon receipt of an Order of the Company (which the Company agrees to deliver promptly), authenticate and deliver a new Global Security; provided, however, that the
Certificated Securities presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in accordance with the proviso to the first sentence of Section 2.05(a) hereof.

 (d) Transfers to the Company. Nothing contained in the Indenture or in the Securities shall prohibit the sale or other transfer of
any Securities (including beneficial interests in Global Securities) to the Company, or any of its Subsidiaries or any of its Affiliates. 
 Section 2.10. CUSIP Numbers. The Company in issuing the Securities may use one or more “CUSIP,” “ISIN” or other similar numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP,”
“ISIN” or other similar numbers in notices of purchase as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on
the Securities or as contained in any notice of a purchase and that reliance may be placed only on the other identification numbers printed on the Securities, and any such purchase shall not be affected by any defect in or 

  

 11 

 
omission of such numbers. The Company shall promptly notify the Trustee of any change in the “CUSIP,” “ISIN” or other similar numbers.

 ARTICLE 3 
 REPURCHASE OF SECURITIES AT OPTION OF HOLDERS 
 Section 3.01. Purchase of Securities at Option of the Holder upon a Fundamental Change. (a) In the event a Fundamental Change shall occur at any time when any Securities remain outstanding, each
Holder shall have the right, at such Holder’s option, to require the Company to purchase all of such Holders’ Securities or any portion of the principal amount thereof that is equal to $1,000 or an integral multiple thereof on a date
specified by the Company (the “Fundamental Change Repurchase Date”) that is not less than 20 nor more than 30 Business Days after the date the Company mails the Fundamental Change Company Notice pursuant to
Section 3.01(b) below, at a purchase price in Cash equal to 100% of the principal amount of the Securities tendered for purchase, plus accrued and unpaid interest (including any Additional Interest) (the “Fundamental Change Repurchase
Price”) to, but not including, the Fundamental Change Repurchase Date, subject to satisfaction by or on behalf of any Holder of the requirements set forth in Section 3.01(d) below. If the Fundamental Change Repurchase Date is after a
Record Date and on or prior to the related Interest Payment Date, the interest payable on such Interest Payment Date will be paid to the Holder of record of the Securities on the relevant Record Date (which may or may not be the same Person to whom
the Company shall pay the Fundamental Change Repurchase Price) and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of the Securities tendered for purchase. No Securities may be purchased at the option of the
Holders upon a Fundamental Change if there has occurred and is continuing an Event of Default other than an Event of Default that is cured by the payment of the Fundamental Change Repurchase Price of the Securities. 
 A “Fundamental Change” shall be deemed to have occurred upon the occurrence of any of the following: 
 (i) a “person” or “group” within the meaning of Section 13(d)(3) of the Exchange Act becomes the direct or
indirect “beneficial owner,” as defined in Rule 13d-3 under the Exchange Act, of shares of the Common Stock representing more than 50% of the voting power of the Common Stock entitled to vote generally in the election of directors and
(A) files a Schedule 13D or Schedule TO or any other schedule, form or report under the Exchange Act disclosing such beneficial ownership or (B) the Company otherwise becomes aware of any such person or group; or 
 (ii) the Common Stock into which the Securities are then convertible ceases to be listed for trading on the NYSE, the NASDAQ Global Select
Market or NASDAQ Global Market or another national securities exchange and is not then quoted on an established automated over-the-counter trading market in the United States; or 
 (iii) a consolidation, merger or binding share exchange, or any conveyance, transfer, sale, lease or other disposition in a single
transaction or a series of transactions of all or substantially all of the Company’s properties and assets other than: 
 (A) any transaction: 
 (1) that does not result in any reclassification, conversion, exchange or cancellation of
outstanding shares of the Company’s Capital Stock; and 
 (2) pursuant to which holders of the Company’s Capital
Stock immediately prior to the transaction have the entitlement to exercise, directly or 

  

 12 

 
indirectly, 50% or more of the total voting power of all shares of Capital Stock entitled to vote generally in elections of directors of the continuing or
surviving or successor Person immediately after giving effect to such transaction in substantially the same proportion as their entitlement to exercise, directly or indirectly, voting power of shares of the Company’s Capital Stock entitled to
vote generally in elections of the Company’s directors immediately prior to such transaction; or 
 (B) any transaction
that is effected solely for the purpose of changing the Company’s jurisdiction of incorporation and resulting in a reclassification, conversion or exchange of outstanding shares of Common Stock, if at all, solely into shares of common stock of
the surviving entity or a direct or indirect parent of the surviving corporation; or 
 (C) any transaction with any of the
Company’s wholly-owned subsidiaries, so long as such transaction is not part of a plan or a series of transactions designed with the intention of, or having the effect of merging or consolidating with, or conveying, transferring, selling,
leasing or disposing of all or substantially all of the Company’s properties and assets to any other Person or Persons. 
 (iv) the Company’s shareholders approve any plan or proposal for the Company’s liquidation or dissolution. 
 However, a fundamental
change will be deemed not to have occurred if more than 90% of the consideration in the transaction or transactions (other than Cash payments for fractional shares and Cash payments made in respect of dissenters’ appraisal rights) which
otherwise would constitute a Fundamental Change under clause (iii) above consists of shares of common stock, depositary receipts or other certificates representing common equity interests traded or to be traded immediately following such
transaction on a U.S. national securities exchange and, as a result of the transaction or transactions, the Securities become convertible into such common stock, depositary receipts or other certificates representing common equity interests (and any
rights attached thereto) and other applicable consideration. 
 A “Make-Whole Fundamental Change” shall be deemed to have
occurred upon the occurrence of a Fundamental Change described in clause (i) or clause (iii) of the definition of Fundamental Change above (including the preceding paragraph). 
 For purposes of this Section 3.01, “person” includes any syndicate or group that would be deemed to be a “person” under
Section 13(d)(3) of the Exchange Act. 
 (b) Notice of Make-Whole Fundamental
Change. The Company will give notice of an anticipated Make-Whole Fundamental Change to each Holder (and to beneficial owners as required by applicable law) (to the extent the date of such Make-Whole Fundamental Change may reasonably be
anticipated) no later than the 15th Scheduled Trading Day prior to the date on which a Make-Whole Fundamental Change is anticipated to become
effective. 
 (c) Notice of Fundamental Change. Within 15 Business Days after the effective date of each Fundamental
Change, the Company shall notify the Trustee of the Fundamental Change Repurchase Date and shall mail or cause to be mailed a written notice of the Fundamental Change (each such notice, a “Fundamental Change Company Notice”) to each
Holder (and to beneficial owners as required by applicable law) in accordance with Section 1.8 of the Original Indenture. The notice shall include the form of a Fundamental Change Repurchase Notice to be completed by the Holder and shall state,
as applicable: 
  

 13 

 (i) the events causing such Fundamental Change, the Adjustment Date of the Fundamental
Change (in the case of a Make-Whole Fundamental Change) and the date of effectiveness of such Fundamental Change; 
 (ii) that
the Holder has a right to require the Company to purchase the Holder’s Securities; 
 (iii) the date by which the
Fundamental Change Repurchase Notice must be delivered to the Paying Agent in order for a Holder to exercise the Fundamental Change purchase right; 
 (iv) the Fundamental Change Repurchase Date; 
 (v) the Fundamental Change Repurchase Price;

 (vi) the procedures that the Holder must follow to exercise its Fundamental Change purchase right under this
Section 3.01; 
 (vii) the names and addresses of the Paying Agent and the Conversion Agent; 
 (viii) that the Securities must be surrendered to the Paying Agent to collect payment of the Fundamental Change Repurchase Price;

 (ix) that the Fundamental Change Repurchase Price for any Security as to which a Fundamental Change Repurchase Notice has
been duly given and not withdrawn shall be paid promptly following the later of the Fundamental Change Repurchase Date and the time of surrender of such Security; 
 (x) the Conversion Rate (after giving effect to any change in the Conversion Rate that resulted from the Fundamental Change); 

(xi) that the Securities with respect to which a Fundamental Change Repurchase Notice has been given may be converted pursuant to
Article 4 of this First Supplemental Indenture only if either (i) the Fundamental Change Repurchase Notice has been withdrawn in accordance with the terms of this First Supplemental Indenture or (ii) there shall be a default in the payment
of the Fundamental Change Repurchase Price; 
 (xii) the procedures for withdrawing a Fundamental Change Repurchase Notice;

 (xiii) that, unless the Company defaults in making payment of such Fundamental Change Repurchase Price, interest on
Securities surrendered for purchase by the Company shall cease to accrue on and after the Fundamental Change Repurchase Date; and 
 (xiv) subject to Section 2.10 hereof, the CUSIP number(s) of the Securities. 
 If any of the Securities are in the form of a
Global Security, then the Company shall modify such notice to the extent necessary to accord with the Applicable Procedures for repurchases. 
 At the Company’s request, the Trustee shall give the Fundamental Change Company Notice on behalf of the Company and at the Company’s expense; provided, however, that the Company makes such request at least three
Business Days (unless a shorter period shall be consented to by the Trustee) prior to the date by 

  

 14 

 
which such Fundamental Change Company Notice must be given to the Holders in accordance with this Section 3.01(c); provided further,
however, that the text of such notice shall be prepared by the Company. 
 (d) Fundamental Change Repurchase Notice. A
Holder may exercise its right specified in Section 3.01(a) above upon delivery of a written notice (which shall be in substantially the form included in Exhibit A hereto and which may be delivered by letter, overnight courier, hand
delivery, facsimile transmission or in any other written form and, in the case of Global Securities, may be delivered electronically or by other means in accordance with the Applicable Procedures) of the exercise of such rights (a
“Fundamental Change Repurchase Notice”) to, and such Fundamental Change Repurchase Notice must be received by, the Paying Agent no later than the Close of Business on the Business Day immediately preceding the Fundamental Change
Repurchase Date. The Fundamental Change Repurchase Notice must state: 
 (i) if Certificated Securities are to be delivered,
the certificate numbers of the Securities that the Holder shall deliver to be purchased; 
 (ii) the portion of the principal
amount of the Securities that the Holder shall deliver to be purchased, which portion must be in principal amounts of $1,000 or an integral multiple thereof; and 
 (iii) that such Securities are being tendered for and shall be purchased by the Company on the Fundamental Change Repurchase Date pursuant
to the terms and conditions specified in this First Supplemental Indenture. 
 The book-entry transfer or delivery of such Security to the
Paying Agent (together with all necessary endorsements) at the office of the Paying Agent shall be a condition to the receipt by the Holder of the Fundamental Change Repurchase Price; provided, however, that such Fundamental Change
Repurchase Price shall be paid pursuant to this Section 3.01 only if the Security so transferred by book-entry or delivered to the Paying Agent shall conform in all material respects to the description thereof in the related Fundamental Change
Repurchase Notice. 
 The Company shall purchase from the Holder thereof, pursuant to this Section 3.01, a portion of a Security if the
principal amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of this Section 3.01 that apply to the purchase of all of a Security also apply to the purchase of such a portion of such Security. 
 Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this
Section 3.01(d) shall have the right to withdraw such Fundamental Change Repurchase Notice at any time prior to the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written
notice of withdrawal to the Paying Agent in accordance with Section 3.02(b) below. 
 The Paying Agent shall promptly notify the Company
of the receipt by it of any Fundamental Change Repurchase Notices or written notices of withdrawal thereof. 
 (e) Notwithstanding anything
herein to the contrary, in the case of Global Securities, any Fundamental Change Repurchase Notice may be delivered or withdrawn, and such Securities may be surrendered or transferred by book-entry or delivered for purchase, in accordance with the
Applicable Procedures. 
 Section 3.02. Effect of Fundamental Change Repurchase Notice. (a) Upon receipt by the Paying Agent
of a Fundamental Change Repurchase Notice, the Holder of the Security in respect of which such Fundamental Change Repurchase Notice was given shall (unless such Fundamental Change Repurchase Notice 

  

 15 

 
is withdrawn as specified below) thereafter be entitled to receive the Fundamental Change Repurchase Price with respect to such Security. Such Fundamental
Change Repurchase Price shall be paid to such Holder on the later of (i) the Fundamental Change Repurchase Date (provided such Holder has satisfied the conditions in Section 3.01(d) above with respect to such Security) and
(ii) the time of book-entry transfer or delivery of such Security to the Paying Agent by the Holder thereof in the manner required by Section 3.01(d) above. A Security in respect of which a Fundamental Change Repurchase Notice has been
given by the Holder thereof may not be converted pursuant to Article 4 hereof on or after the date of the delivery of such Fundamental Change Repurchase Notice, unless either (i) such Fundamental Change Repurchase Notice has first been validly
withdrawn in accordance with Section 3.02(b) below; or (ii) there shall be a default in the payment of the Fundamental Change Repurchase Price, provided, that the conversion right with respect to such Security shall terminate at the
Close of Business on the date such default is cured and such Security is purchased in accordance herewith. 
 (b) A Fundamental Change
Repurchase Notice may be withdrawn by any Holder delivering such Fundamental Change Repurchase Notice upon delivery of a written notice of withdrawal (which may be delivered by mail, overnight courier, hand delivery, facsimile transmission or in any
other written form and, in the case of Global Securities, may be delivered electronically or by other means in accordance with the Applicable Procedures) to and such notice of withdrawal must be received by the Paying Agent at any time prior to the
Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date, specifying: 
 (i) if
Certificated Securities are to be withdrawn, the certificate numbers of the Securities in respect of which such notice of withdrawal is being submitted; 
 (ii) the principal amount of the Securities in respect of which such notice of withdrawal is being submitted, which principal amount must be $1,000 or an integral multiple thereof; and 
 (iii) the principal amount, if any, of the Securities that remains subject to the original Fundamental Change Repurchase Notice and that
has been or shall be delivered for purchase by the Company. 
 Section 3.03. Deposit of Fundamental Change Repurchase Price. On
or prior to 11:00 a.m., New York City time, on a Fundamental Change Repurchase Date, the Company shall deposit with the Paying Agent (or if the Company or an Affiliate of the Company is acting as the Paying Agent, shall segregate and hold
in trust as provided in Section 2.04 hereof) an amount in Cash (in immediately available funds if deposited on such Fundamental Change Repurchase Date) sufficient to pay the aggregate Fundamental Change Repurchase Price of all the Securities or
portions thereof that are to be purchased on that Fundamental Change Repurchase Date. 
 If the Paying Agent holds, in accordance with the
terms hereof, at 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date, Cash sufficient to pay the aggregate Fundamental Change Repurchase Price of all Securities for which a Fundamental Change Repurchase Notice has
been delivered and not validly withdrawn in accordance with this First Supplemental Indenture, then, on and after such Fundamental Change Repurchase Date, such Securities shall cease to be outstanding and interest (including any Additional Interest)
on such Securities shall cease to accrue, whether or not such Securities are transferred by book-entry or delivered to the Paying Agent, and the rights of the Holders in respect thereof shall terminate (other than the right to receive the
Fundamental Change Repurchase Price upon delivery of such Securities by their Holders to the Paying Agent). 
 Section 3.04.
Securities Purchased in Part. Any Certificated Security that is to be purchased only in part shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires, due 

  

 16 

 
endorsement by, or a written instrument of transfer in form reasonably satisfactory to the Company and the Trustee duly executed by, the Holder thereof or
such Holder’s attorney duly authorized in writing), and promptly after a Fundamental Change Repurchase Date, the Company shall issue and the Trustee shall, upon receipt of an Order from the Company (which the Company agrees to deliver
promptly), authenticate and deliver to the Holder of such Security, without service charge, a new Security or Securities, of such authorized denomination or denominations as may be requested by such Holder, in aggregate principal amount equal to,
and in exchange for, the portion of the principal amount of the Security so surrendered that is not purchased. 
 Section 3.05.
Repayment to the Company. To the extent that the aggregate amount of Cash deposited by the Company pursuant to Section 3.03 above exceeds the aggregate Fundamental Change Repurchase Price of the Securities or portions thereof that the
Company is obligated to purchase on the Fundamental Change Repurchase Date, then, within one Business Day after the Fundamental Change Repurchase Date, the Paying Agent shall return any such excess Cash to the Company. 
 Section 3.06. Compliance with Securities Laws upon Purchase of Securities. When complying with the provisions of Article 3 hereof
(provided that such offer or purchase constitutes an “issuer tender offer” for purposes of Rule 13e-4 (which term, as used herein, includes any successor provision thereto) under the Exchange Act at the time of such offer or
purchase), and subject to any exemptions available under applicable law, the Company shall: 
 (a) comply with Rule 13e-4,
Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable; and 
 (b) otherwise comply with all
federal and state securities laws so as to permit the rights and obligations in connection with any purchase pursuant to this Article 3 to be exercised in the time and in the manner specified herein. 
 ARTICLE 4 
 CONVERSION

 Section 4.01. Conversion Privilege. The Securities shall be convertible in accordance with their terms and in accordance
with and subject to this Article 4 into a number of shares of Common Stock equal to the Conversion Rate, subject to the provisions of Section 4.02 below regarding fractional shares, at any time prior to the Close of Business on the Business Day
immediately preceding the Maturity Date. Securities may be converted only in denominations of $1,000 principal amount and integral multiples thereof. 
 Section 4.02. Conversion Rate. (a) The Securities shall be convertible into a number of shares of Common Stock at an initial conversion rate (the “Initial Conversion Rate”) of
260.4167 shares of Common Stock (subject to adjustments as provided in Section 4.02(c), Section 4.06 and Section 4.11 of this First Supplemental Indenture, as so adjusted from time to time, the “Conversion Rate”) per
$1,000 principal amount of Securities. 
 A Holder of a Security otherwise entitled to a fractional share will receive Cash in an amount
equal to the value of such fractional share based on the Closing Price of the Common Stock on the related Conversion Date. 
 A Security for
which a Holder has delivered a Fundamental Change Repurchase Notice requiring the Company to purchase the Securities may be surrendered for conversion only if such notice is withdrawn in accordance with this First Supplemental Indenture. 

 

 17 

 (b) If a Holder elects to convert Securities in connection with a Make-Whole Fundamental Change, then the
Conversion Rate of the Securities being converted by such Holder shall be increased by an additional number of shares of Common Stock (the “Additional Shares”) set forth in Exhibit B. For the avoidance of doubt, the increases
provided for in this Section 4.02(b) shall only be made with respect to the Securities being converted in connection with such Make-Whole Fundamental Change and shall not be effective as to any Securities not so converted. For purposes of this
Section 4.02(b), a conversion shall be deemed to be “in connection” with a Make-Whole Fundamental Change if it occurs during the period that begins on (and includes) the 15th Scheduled Trading Day prior to the anticipated effective
date of such Make-Whole Fundamental Change, as specified pursuant to the notice provided pursuant to Section 3.01(b) hereof, and ends on (and includes) the Fundamental Change Repurchase Date relating to such Make-Whole Fundamental Change as set
forth in Article 3 hereof. 
 (c) The increase in the Conversion Rate, expressed as a number of Additional Shares to be received per $1,000
principal amount of Securities, will be determined by the Company by reference to the table attached as Exhibit B hereto, based on the earliest of the date on which the Make-Whole Fundamental Change is publicly announced, occurs or becomes
effective (the “Adjustment Date”) and the price paid or deemed to be paid per share of Common Stock in the transaction constituting the Make-Whole Fundamental Change (the “Stock Price”) subject to adjustment as set
forth in the next paragraph; provided that if a Holder of the Common Stock receives only Cash in connection with such transaction, the Stock Price shall be the Cash amount paid per share. In all other cases, the Stock Price will be the
average of the Closing Prices of the Common Stock over the thirty consecutive Trading Days prior to, but not including, the date of effectiveness of the Make-Whole Fundamental Change. If the Stock Price is between two Stock Price amounts on the
table or the Adjustment Date is between two Adjustment Dates on the table, the number of Additional Shares will be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Price
amounts and the earlier and later adjustment dates based on a 365-day year, as applicable. If the Stock Price is in excess of $30.00 per share (subject to adjustment in the same manner as the Stock Price), no increase in the Conversion Rate will be
made and if the Stock Price is less than $3.20 per share (subject to adjustment in the same manner as the Stock Price), no increase in the Conversion Rate will be made. Notwithstanding anything to the contrary, in no event will the number of
Additional Shares to be added to the Conversion Rate pursuant to Section 4.02(b) above and this Section 4.02(c) exceed 52.0833 shares (subject to adjustment in the same manner in which the Conversion Rate is adjusted, as set forth in
Section 4.06 hereof) per $1,000 principal amount of Securities. 
 The Stock Prices set forth in the first column of the table attached
as Exhibit B hereto will be adjusted as of any date on which the Conversion Rate is adjusted, as set forth in Section 4.06 hereof. The adjusted Stock Prices will 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 the Conversion Rate as so adjusted. The number of Additional Shares will be
adjusted in the same manner as the Conversion Rate as set forth in Section 4.06 hereof. 
 Securities surrendered for conversion in
connection with a Make-Whole Fundamental Change will be settled as follows: 
  

	 	•	 	 If the Conversion Date occurs prior to the date of effectiveness of such Make-Whole Fundamental Change, settlement shall occur on the third Trading Day immediately
following such date of effectiveness; and 

  

	 	•	 	 If the Conversion Date occurs on or following the date of effectiveness of such Make-Whole Fundamental Change, settlement shall occur on the third Trading Day
immediately following such Conversion Date. 

  

 18 

 The Company will settle such conversions by delivering Reference Property equivalent to shares of the Common Stock based
on the increased Conversion Rate resulting from such Make-Whole Fundamental Change. 
 Notwithstanding the foregoing, if the Reference
Property with respect to a Make-Whole Fundamental Change consists entirely of Cash, (i) the applicable Stock Price used to determine the amount of Cash payable upon conversion of the Securities in connection with a Make-Whole Fundamental Change
will be the actual amount of Cash paid per share of Common Stock in such Make-Whole Fundamental Change and (ii) Securities surrendered for conversion in connection with such Make-Whole Fundamental Change will be settled as follows: 

 

	 	•	 	 If the Conversion Date occurs prior to the date of effectiveness of such Make-Whole Fundamental Change, settlement shall occur on the third Business Day immediately
following such date of effectiveness; and 

  

	 	•	 	 If the Conversion Date occurs on or following the date of effectiveness of such Make-Whole Fundamental Change, settlement shall occur on the third Business Day
following such Conversion Date. 

 For the avoidance of doubt, in the event Securities are surrendered for conversion in
connection with an anticipated Make-Whole Fundamental Change and such Make-Whole Fundamental Change does not in fact occur, no Additional Shares will be added to the Conversion Rate and no additional Cash or Reference Property will be paid as a
result of the related anticipated Make-Whole Fundamental Change, and settlement shall occur on the third Business Day following the date on which the transaction giving rise to the anticipated Make-Whole Fundamental Change is terminated or
abandoned. 
 Section 4.03. Conversion Procedure. (a) The right of conversion attaching to any Security may be exercised at
any time during which conversion is permitted in accordance with Section 4.01 hereof (i) if such Security is represented by a Global Security, by book-entry transfer to the Conversion Agent through the facilities of the Depositary in
accordance with the Applicable Procedures, or (ii) if such Security is represented by a Certificated Security, by delivery of such Security at the specified office of the Conversion Agent, accompanied, in either case, by: (1) a duly signed
and completed conversion notice, in the form as set forth on the reverse of Security attached hereto as Exhibit A (a “Conversion Notice”); (2) if such Certificated Security has been lost, stolen, destroyed or mutilated, a
notice to the Conversion Agent in accordance with Section 2.06 hereof regarding the loss, theft, destruction or mutilation of the Security and such security or indemnity as required pursuant to Section 2.06 hereof; (3) appropriate
endorsements and transfer documents if required by the Conversion Agent; and (4) payment of any tax or duty, in accordance with Section 4.04 hereof, which may be payable in respect of any transfer involving the issue or delivery of the
Common Stock in the name of a Person other than the Holder of the Security. The date on which the Holder satisfies all of those requirements is the “Conversion Date.” The Securities will be deemed to be converted immediately prior
to the Close of Business on the Conversion Date. The Company shall deliver the shares to the Holder through a Conversion Agent in the form of a certificate for the number of whole shares of Common Stock issuable upon the conversion or, in the case
of holders of Securities in book-entry form with DTC, in accordance with DTC customary practices. In each case, the Company shall also deliver to such holder Cash in lieu of any fractional shares pursuant to Section 4.02(a) of this First
Supplemental Indenture and Cash with respect to any Early Conversion Make-Whole Amount pursuant to Section 4.10 hereof. The Company shall deliver such shares and Cash, except as set forth in Section 4.02(c) and subject to Section 4.04
of this First Supplemental Indenture, in any event no later than the third Trading Day immediately following the Conversion Date. 
  

 19 

 (b) The Person in whose name the Security is registered shall be deemed to be a shareholder of record
immediately prior to the Close of Business on the Conversion Date; provided, however, that no surrender of a Security or satisfaction of the other conditions in Section 4.03(a) above on any date when the stock transfer books of
the Company shall be closed shall be effective to constitute the Person or Persons entitled to receive the shares of Common Stock upon such conversion as the record holder or holders of such shares of Common Stock on such date, but such surrender
shall, provided that all such conditions have been satisfied, be effective to constitute the Person or Persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at the Close of Business
on the next succeeding day on which such stock transfer books are open. Upon conversion of a Security, such person shall no longer be a Holder of such Security. 
 (c) Subject to the Company’s obligations under Section 4.10 hereof the Company’s delivery to the Holder of the full number of shares of Common Stock into which the Security is convertible, together with
any Cash payment for such holder’s fractional shares, will be deemed to satisfy the Company’s obligation to pay the principal amount of the Security and to satisfy the Company’s obligation to pay accrued and unpaid interest (including
Additional Interest, if any) to, but not including, the Conversion Date. As a result, accrued interest is deemed paid in full rather than cancelled, extinguished or forfeited. 
 (d) Upon surrender of a Security that is converted in part, the Company shall execute, and the Trustee shall, upon receipt of an Order of the Company,
authenticate and deliver to the Holder, a new Security equal in principal amount of the unconverted portion of the Security surrendered. 
 Section 4.04. Taxes on Conversion. If a Holder converts a Security, the Company shall pay any documentary, stamp or similar issue or transfer taxes or duties relating to the issuance or delivery of shares of Common Stock upon
exercise of such conversion rights. However, the Holder shall pay any tax or duty which may be payable relating to any transfer involving the issuance or delivery of shares of Common Stock or Cash in a name other than the Holder’s name. The
Conversion Agent may refuse to deliver the certificate representing shares of Common Stock being issued in a name other than the Holder’s name or Cash payable to a name other than the Holder’s name until the Conversion Agent receives a sum
sufficient to pay any tax or duties which will be due because the shares are to be issued or the Cash is to be paid in a name other than the Holder’s name. Nothing herein shall preclude any tax withholding required by law or regulation.

 Section 4.05. Company to Provide Stock. (a) The Company shall, prior to the issuance of any Securities hereunder, and
from time to time as may be necessary, reserve at all times and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, a sufficient number of shares of Common Stock deliverable upon conversion of all of the
Securities. 
 (b) All shares of Common Stock that may be issued upon conversion of the Securities shall be newly issued shares or shares
held in the treasury of the Company, shall be duly authorized, validly issued, fully paid and nonassessable and shall be free of any preemptive rights and free of any lien or adverse claim other than a lien or claim created by or with respect to the
Holder of the Securities being converted. 
 (c) The Company shall comply with all applicable securities laws regulating the offer and
delivery of any Common Stock upon conversion of Securities and, if the Common Stock is then listed or quoted on the NYSE, the NASDAQ Global Select Market, NASDAQ Global Market or any other United States national or regional securities exchange or
other market, shall list or cause to have quoted and keep listed and quoted the shares of Common Stock issuable upon conversion of the Securities to the extent permitted or required by the rules of such exchange or market; provided,
however, that, if the rules of such automated quotation system or exchange permit the Company to defer the listing of such Common Stock until the first conversion of the Securities into Common Stock in accordance with the provisions of this
First Supplemental Indenture, the 

  

 20 

 
Company covenants to list such Common Stock issuable upon conversion of the Securities in accordance with the requirements of such automated quotation system
or exchange at such time. 
 Section 4.06. Adjustment of Conversion Rate. This Section 4.06 describes adjustments to the
Conversion Rate to be made in connection with the events described below, as well as events that will not result in adjustment of the Conversion Rate, treatment of rights and treatment of Reference Property. 
 (a) If the Company, at any time or from time to time while any of the Securities are outstanding, issues shares of Common Stock as a dividend or
distribution on shares of Common Stock, or if the Company effects a share split or share combination in respect of the Common Stock, then 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 Record Date for such dividend or distribution, or the Open of Business on the effective date of such share split or
combination, as applicable;
			
	CR'	 	=	  	the new Conversion Rate in effect immediately after the Open of Business on the Record Date for such dividend or distribution, or the Open of Business on the effective date of such share split
or share combination, as applicable;
			
	OS0	 	=	  	the number of shares of Common Stock outstanding immediately prior to the Open of Business on the Record Date for such dividend or distribution, or the Open of Business on the effective date of
such share split or share combination, as applicable; and
			
	OS'	 	=	  	the number of shares of Common Stock outstanding immediately after such dividend or distribution, or the Open of Business on the effective date of such share split or share combination, as
applicable.

 The Company will not pay any dividend or make any distribution on shares of Common Stock held in
treasury by the Company. If any dividend or distribution of the type described in this Section 4.06(a) is declared but not so paid or made, or the outstanding shares of Common Stock are not split or combined, as the case may be, the Conversion Rate
shall again be adjusted to the Conversion Rate which would then be in effect if such dividend, distribution, share split or share combination had not been declared. 
 (b) Except as otherwise provided for by Section 4.06(d) below, if the Company, at any time or from time to time while any of the Securities are outstanding, distributes to all or substantially all holders of its
outstanding shares of Common Stock any rights or warrants entitling them for a period of not more than 45 calendar days from the Record Date of such distribution to subscribe for or purchase shares of Common Stock at a price per share less than the
Closing Price of the Common Stock on the Trading Day immediately preceding the Record Date of such distribution, the Conversion Rate shall be adjusted based on the following formula: 
 

 
  

 21 

					
	where	  	
			
	CR0	 	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Record Date for such distribution;
			
	CR'	 	=	  	the new Conversion Rate in effect immediately after the Open of Business on the Record Date for such distribution;
			
	OS0	 	=	  	the number of shares of Common Stock outstanding immediately prior to the Open of Business on the Record Date for such distribution;
			
	X	 	=	  	the total number of shares of Common Stock issuable pursuant to such rights or warrants; and
			
	Y	 	=	  	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights or warrants divided by the average of the Closing Prices of the Common Stock over the ten
consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend Date for such distribution.

 To the extent that shares of Common Stock are not delivered pursuant to such rights or warrants
upon the expiration or termination of such rights or warrants, the Conversion Rate shall be readjusted to the Conversion Rate which would then be in effect had the adjustments made upon the distribution of such rights or warrants been made on the
basis of the delivery of only the number of shares of Common Stock actually delivered. In the event that such rights or warrants are not so distributed, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in
effect if the announcement with respect to such rights, warrants or convertible securities had not been made. 
 In determining the aggregate
price payable to exercise such rights or warrants, there shall be taken into account any amount payable on exercise thereof, with the value of such consideration, if other than Cash, to be determined in good faith by the Company’s Board of
Directors. 
 (c) If the Company, at any time or from time to time while any of the Securities are outstanding, shall, by dividend or
otherwise, distribute to all or substantially all holders of its Common Stock shares of any class of Capital Stock of the Company (other than Common Stock as covered by Section 4.06(a) above), evidences of its indebtedness, assets, property or
rights or warrants to acquire the Company’s Capital Stock or other securities, but excluding (i) dividends or distributions as to which an adjustment under Section 4.06(a), Section 4.06(b) or Section 4.06(d) hereof shall
apply, (ii) dividends or distributions paid exclusively in Cash and (iii) Spin-Offs to which the provision set forth below in this Section 4.06(c) shall apply (any of such shares of Capital Stock, indebtedness, assets, property or
rights or warrants to acquire the Company’s Common Stock or other securities, hereinafter in this Section 4.06(c) called the “Distributed Property”), then, in each such case 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 Record Date for such distribution;

  

 22 

					
			
	CR'	 	=	  	the new Conversion Rate in effect immediately after the Open of Business on the Record Date for such distribution;
			
	SP0	 	=	  	the average of the Closing Prices of the Common Stock over the ten consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and

			
	FMV	 	=	  	the fair market value (as determined in good faith by the Company’s Board of Directors) of the portion of Distributed Property with respect to each outstanding share of Common Stock on the
Record Date for such distribution.

 Notwithstanding the foregoing, if the then
fair market value (as so determined) of the portion of the Distributed Property so distributed applicable to one share of Common Stock is equal to or greater than SP0 as set forth above, in lieu of the foregoing adjustment, the Company shall distribute to each Holder on the date the Distributed Property is distributed to holders of Common Stock, but without requiring such Holder
to convert its Securities, the amount of Distributed Property such Holder would have received had such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the record date fixed for determination for stockholders entitled
to receive such distribution. If such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such Record Date had not been fixed. If the Board of
Directors determines the fair market value of any distribution for purposes of this Section 4.06(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 average of the Closing Prices of the Common Stock for purposes of calculating SP0 in the formula in this
Section 4.06(c). 
 With respect to an adjustment pursuant to this Section 4.06(c) where there has been a payment of a dividend or
other distribution on the Common Stock consisting 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 (a “Spin-Off”), the Conversion
Rate in effect immediately before the Close of Business on the tenth Trading Day immediately following, and including, the effective date of the Spin-Off shall be increased based on the following formula: 
 

 
  

					
	where	  	
			
	CR0	 	=	  	the Conversion Rate in effect immediately prior to the Close of Business on the 10th Trading
Day immediately following, and including, the effective date of the Spin-Off;
			
	CR'	 	=	  	the new Conversion Rate in effect from and after the Close of Business on the 10th Trading
Day immediately following, and including, the effective date of the Spin-Off;
			
	FMV	 	=	  	the average of the Closing Prices of the Capital Stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock over the 10 consecutive Trading
Day period immediately following, and including, the effective date of the Spin-Off; and
			
	MP0	 	=	  	the average of the Closing Prices of Common Stock over the 10 consecutive Trading Day period immediately following, and including, the effective date of the Spin-Off.

  

 23 

 Such adjustment shall occur on the 10th Trading Day immediately following, and including, the effective date of the Spin-Off; provided that, for purposes of determining the Conversion Rate,
in respect of any conversion during the 10 Trading Days following the effective date of any Spin-Off, references to 10 Trading Days within the portion of this Section 4.06(c) related to “Spin-Offs” shall be deemed replaced with such
lesser number of Trading Days as have elapsed between the effective date of such Spin-Off and the relevant Conversion Date. 
 For purposes
of this Section 4.06(c), Section 4.06(a) and Section 4.06(b) hereof, any dividend or distribution to which this Section 4.06(c) is applicable that also includes shares of Common Stock, or rights or warrants to subscribe for or
purchase shares of Common Stock to which Section 4.06(a) or 4.06(b) hereof applies (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences of indebtedness, assets or shares of Capital Stock other than such
shares of Common Stock or rights or warrants to which Section 4.06(a) or 4.06(b) hereof applies (and any Conversion Rate adjustment required by this Section 4.06(c) with respect to such dividend or distribution shall then be made)
immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights or warrants to which Section 4.06(a) or 4.06(b) hereof applies (and any further Conversion Rate adjustment required by
Section 4.06(a) and 4.06(b) hereof with respect to such dividend or distribution shall then be made), except (A) the Open of Business on the Record Date of such dividend or distribution shall be substituted for “the Open of Business
on the Record Date,” “the Open of Business on the Record Date or the Open of Business on the effective date,” “after the Open of Business on the Record Date for such dividend or distribution or the Open of Business on the
effective date of such share split or share combination” and “the Open of Business on the Record Date for such distribution” within the meaning of Section 4.06(a) and Section 4.06(b) hereof and (B) any shares of Common
Stock included in such dividend or distribution shall not be deemed “outstanding immediately prior to the Open of Business on the Record Date or the Open of Business on the effective date” within the meaning of Section 4.06(a) hereof.

 (d) If the Company, at any time or from time to time while any of the Securities are outstanding, distributes rights or warrants to all
holders of Common Stock entitling the holders thereof to subscribe for, purchase or convert into shares of the Company’s Capital Stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a
specified event or events (“Trigger Event”): (x) are deemed to be transferred with such shares of Common Stock; (y) are not exercisable; and (z) are also issued in respect of future issuances of Common Stock, shall be
deemed not to have been distributed for purposes of Section 4.06(c) above, (and no adjustment to the Conversion Rate under Section 4.06(c) above will be required) until the occurrence of the earliest Trigger Event and a distribution or deemed
distribution under the terms of such rights or warrants and an appropriate adjustment (if any is required) to the Conversion Rate shall be made in the same manner as provided for under Section 4.06(c) above. If any such right or warrant are subject
to events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date
of distribution and Record Date with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof). In addition, in the event of any
distribution (or deemed distribution) of rights or warrants (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate
under this Section 4.06(d) was made, (1) in the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final
redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a Cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with
respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants that shall have
expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights or warrants had not been issued. 
  

 24 

 (e) If the Company, at any time or from time to time while any of the Securities are outstanding, makes a
Cash dividend or distribution to all or substantially all holders of Common Stock, 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 Business Day immediately prior to the Record Date for such dividend or distribution;
			
	CR'	 	=	  	the new Conversion Rate in effect immediately after the Open of Business on the Record Date for such dividend or distribution;
			
	SP0	 	=	  	the average Closing Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and
			
	C	 	=	  	the amount in Cash per share the Company distributes or dividends to holders of Common Stock.

 Notwithstanding the foregoing, if the
portion of the Cash so distributed applicable to one share of Common Stock is equal to or greater than SP0 as set forth above, in lieu of the
foregoing adjustment, the Company shall distribute to each Holder on the date the Cash dividend or distribution is paid to holders of Common Stock, but without requiring such Holder to convert its Securities, for each $1,000 principal amount of
Securities, the amount of Cash such Holder would have received had such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the Record Date for such dividend or distribution. If such dividend or distribution is not so
paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 For the avoidance of doubt, for purposes of this Section 4.06(e), in the event of any reclassification of the Common Stock, as a result of which the Securities become convertible into more than one class of Common
Stock, if an adjustment to the Conversion Rate is required pursuant to this Section 4.06(e), references in this Section to one share of Common Stock or Closing Price of one share of Common Stock shall be deemed to refer to a unit or to the price of
a unit consisting of the number of shares of each class of Common Stock into which the Securities are then convertible equal to the numbers of shares of such class issued in respect of one share of Common Stock in such reclassification. The above
provisions of this paragraph shall similarly apply to successive reclassifications. 
 (f) If the Company or any of its Subsidiaries makes a
payment of Cash or other consideration in respect of a tender offer or exchange offer for all or any portion of the Common Stock, where such Cash and the value of any such other consideration included in the payment per share of Common Stock validly
tendered or exchanged exceeds the Closing Price of the Common Stock on the Trading Day next succeeding the last date (the “expiration date”) on which tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be
amended), the Conversion Rate shall be increased based on the following formula: 
 

 
  

 25 

					
	where	  	
			
	CR0	 	=	  	the Conversion Rate in effect immediately prior to the Close of Business on the Trading Day next succeeding the expiration date;
			
	CR'	 	=	  	the new Conversion Rate in effect immediately after the Close of Business on the Trading Day next succeeding the expiration date;
			
	AC	 	=	  	the aggregate value of all Cash and any other consideration (as determined in good faith by the Company’s Board of Directors) paid or payable for shares purchased in such tender or exchange
offer;
			
	OS0	 	=	  	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires;
			
	OS'	 	=	  	the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to such tender offer or exchange offer);
and
			
	SP'	 	=	  	the Closing Price of Common Stock on the Trading Day next succeeding the expiration date.

 If the Company or a Subsidiary is obligated to purchase shares of Common Stock pursuant to any
such tender or exchange offer, but the Company or such Subsidiary is permanently prevented by applicable law from effecting any such purchases or all or any portion of such purchases are rescinded, then the Conversion Rate shall again be adjusted to
be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made or had only been made in respect of the purchases that had been effected. Except as set forth in the preceding sentence, if an adjustment to the
Conversion Rate pursuant to this Section 4.06(f) with respect 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 4.06(f). 
 (g) For purposes of this Section 4.06 the term “Record Date” shall mean, with respect to any
dividend, distribution or other transaction or event in which the holders of Common Stock have the right to receive any Cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or converted into
any combination of Cash, securities or other property, the date fixed for determination of shareholders entitled to receive such Cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or
otherwise). 
 (h) If application of the formulas provided in Sections 4.06(a), 4.06(b), 4.06(c), 4.06(d), 4.06(e) or 4.06(f) above would
result in a decrease in the Conversion Rate, no adjustment (other than a readjustment as described in such sections) to the Conversion Rate shall be made except in the case of a share split or combination of the Common Stock. 
 (i) If one or more events occur requiring an adjustment be made to the Conversion Rate for a particular period, adjustments to the Conversion Rate shall
be determined by the Company’s Board of Directors to reflect the combined impact of such Conversion Rate adjustments, as set out in this Section 4.06, during such period. 
 Section 4.07. No Adjustment. No adjustment in the Conversion Rate shall be required unless the adjustment would result in a change in the
Conversion Rate of at least 1.00%; provided, however, that any adjustment which by reason of this Section 4.07 is not required to be made shall be carried forward and the 

  

 26 

 
Company shall make such adjustment, regardless of whether the aggregate adjustment is less than 1.00%, within one year of the first such adjustment carried
forward or in connection with any conversion of Securities. All calculations under this Article 4 shall be made to the nearest one-ten thousandth (1/10,000) of a cent or to the nearest one-ten thousandth (1/10,000) of a share, as
the case may be. 
 No adjustment in the Conversion Rate need be made for (i) issuances of Common Stock pursuant to any present or
future Company plan for reinvestment of dividends or interest payable on the Company’s securities or the investment of additional optional amounts thereunder in shares of Common Stock, (ii) upon the issuance of any shares of Common Stock
or options or rights to purchase shares of Common Stock pursuant to any present or future employee, director or consultant benefit plan or program of, or assumed by, the Company or any of its Subsidiaries, (iii) upon the issuance of any shares
of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described under (ii) above and outstanding as of the date the Securities were first issued, (iii) a change in the par value of
the Common Stock, (iv) upon the issuance of any shares of Common Stock pursuant to the Common Stock offering made concurrently with the offering of the Securities (including upon the initial issuance and subsequent issuance of shares of Common
Stock if the over-allotment option is exercised by one or more of the underwriters thereunder) or (v) accrued and unpaid interest, including Additional Interest, if any. 
 No adjustment to the Conversion Rate need be made pursuant to Section 4.06 above for a transaction if Holders are permitted to participate in the
transaction without conversion, concurrently with the holders of Common Stock, on a basis and with notice that the Board of Directors of the Company determines in good faith to be fair and appropriate in light of the basis and notice to holders of
Common Stock participating in the transaction. 
 Whenever a provision of this First Supplemental Indenture requires the calculation of an
average of the Closing Price over a span of multiple days, the Company will make appropriate adjustments to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an 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 from which the average is to be calculated. 
 Section 4.08. Shareholder Rights Agreements. Upon conversion of the Securities, the Holders shall receive, in addition to any shares of
Common Stock issuable upon such conversion, any associated rights issued under any shareholder rights agreement the Company adopts or implements that provides that each share of Common Stock issued upon conversion of the Securities at any time prior
to the distribution of separate certificates representing such rights will be entitled to receive such rights unless, prior to conversion, the rights have separated from the Common Stock, expired, terminated or been redeemed or exchanged in
accordance with such rights plan, and no adjustment shall be made to the Conversion Rate pursuant to Section 4.06(d) hereof. If, prior to any conversion, the rights have separated from the Common Stock, 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, evidences of indebtedness, assets, property or rights or warrants as described in Section 4.06(d) hereof, subject to readjustment in
the event of the expiration, termination or redemption of such rights. 
 Section 4.09. Effect of Reclassification, Consolidation,
Merger or Sale on Conversion Privilege. If (1) there shall occur (a) any reclassification of the Common Stock (other than a change only in par value, or from par value to no par value, or from no par value to par value, or a change as
a result of a subdivision or combination of Common Stock); (b) a statutory share exchange, consolidation, merger or combination involving the Company other than a merger in which the Company is the continuing corporation and which does not
result in any reclassification of, or change (other than in par value, or from par value to no par value, or from no par value to par value, or a change as a result of a subdivision or combination of Common Stock) in, outstanding shares of Common
Stock; or (c) a sale or conveyance as an entirety or substantially as an entirety of the property and assets of the Company, directly or indirectly, to another Person; and (2) pursuant to such 

  

 27 

 
reclassification, statutory share exchange, consolidation, merger, combination, sale or conveyance, holders of outstanding shares of Common Stock would be
entitled to receive stock (other than Common Stock), other securities, other property, assets or Cash (or any combination thereof) for such shares of Common Stock (any such event a “Reorganization Event”), then the Company, or such
successor or surviving, purchasing or transferee Person, as the case may be, shall, as a condition precedent to such Reorganization Event, execute and deliver to the Trustee a supplemental indenture signed by the principal executive officer,
principal financial officer or principal accounting officer of the Company and at least one other Officer of the Company and providing that, at the effective time of the Reorganization Event, the settlement of the Securities tendered for conversion
will be based on, and the property deliverable in respect of any such settlement will consist of, the kind and amount of shares of stock, other securities or other property or assets (including Cash or any combination thereof) that holders of shares
of Common Stock are entitled to receive in respect of each share of Common Stock upon such Reorganization Event (the “Reference Property”). If the Reorganization Event causes the Common Stock to be converted into the right to
receive more than a single type of consideration (determined based in part upon any form of shareholder election), the Reference Property into which the Securities will be convertible will 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. None of the foregoing provisions shall affect the right of a holder of Securities to convert its Securities in accordance with the provisions
of this Article 4 prior to the effective date of such Reorganization Event. Such supplemental indenture shall provide for adjustments of the Conversion Rate which shall be as nearly equivalent as may be practicable to the adjustments of the
Conversion Rate provided for in this Article 4. The provisions of this Section 4.09 shall similarly apply to successive Reorganization Events. 
 Section 4.10. Early Conversion Make-Whole Amount. Holders who convert Securities prior to April 15, 2011 shall receive for each $1,000 principal amount of Securities converted, in addition to a number of shares of Common
Stock determined pursuant to Section 4.02(b) hereof, the Cash proceeds, subject to the limitation described below, from the liquidation by the Escrow Agent pursuant to Section 4(c) of the Pledge and Escrow Agreement of the Allocable
Collateral for each $1,000 principal amount of Securities being converted (such Cash proceeds, the “Early Conversion Make-Whole Amount”); provided that, as set forth in the Pledge and Escrow Agreement, if a Holder converts
Securities after the Close of Business on any Record Date but prior to the next Interest Payment Date, the Government Securities with respect to the Securities being converted relating to the interest payable on such Securities on such Interest
Payment Date shall be excluded from such sale and from the Early Conversion Make-Whole Amount and proceeds from such portion of the Government Securities shall be paid to the Holder of such Securities on the Record Date corresponding to such
Interest Payment Date.  
 Section 4.11. Other Adjustments. Subject to applicable stock exchange rules and listing
standards, the Company shall be entitled to 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 best interests in the Company; provided
the Company has given to Holders and the Trustee at least 15 days’ prior notice, in accordance with Sections 1.7 and 1.8 of the Original Indenture, of any such increase in the Conversion Rate and the period during which it will be in effect.
Subject to applicable stock exchange rules and listing standards, the Company shall be entitled to increase the Conversion Rate, in addition to the events requiring an increase in the Conversion Rate pursuant to Section 4.06 hereof, as it in
its discretion shall determine to be advisable in order to avoid or diminish any tax to shareholders in connection with any stock dividends, subdivisions of shares, distributions of rights to purchase stock or securities or distributions of
securities convertible into or exchangeable for stock hereafter made by the Company to its shareholders. 
 Section 4.12. Notice of
Adjustment. Whenever the Conversion Rate or conversion privilege is adjusted, the Company shall promptly mail to Securityholders a notice of the adjustment in accordance with Section 1.8 of the Original Indenture, and file with the Trustee
an Officers’ Certificate briefly stating the Conversion Rate, the facts giving rise to the adjustment and the manner of computing it. Unless and until the 

  

 28 

 
Trustee shall receive an Officers’ Certificate setting forth an adjustment of the Conversion Rate, the Trustee may assume without inquiry that the
Conversion Rate has not been adjusted and that the last Conversion Rate of which it has knowledge remains in effect. 
 Section 4.13.
Trustee’s Disclaimer. The Trustee shall have no duty to determine when an adjustment under this Article 4 should be made, how it should be made or what such adjustment should be, but may accept as conclusive evidence of that fact or the
correctness of any such adjustment set forth in, and shall be protected in relying upon, an Officers’ Certificate, including the Officers’ Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to
Section 4.12 hereof. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities, and the Trustee shall not be responsible for the Company’s failure to comply with any
provisions of this Article 4. 
 The Trustee shall not be under any responsibility to determine the correctness of any provisions contained
in any supplemental indenture executed pursuant to Section 4.09, but may accept as conclusive evidence of the correctness thereof, and shall be fully protected in relying upon, the Officers’ Certificate and Opinion of Counsel with respect
thereto which the Company is obligated to file with the Trustee pursuant to Section 4.09. 
 Section 4.14. Settlement Upon
Conversion. Except as described in this Section 4.14 and in Section 4.10 hereof, the Company will not make any payment in Cash or Common Stock or other adjustment for accrued and unpaid interest (including Additional Interest, if any)
on any Securities when they are converted. If Securities are surrendered for conversion after the Close of Business on a Record Date for the payment of interest but prior to the Open of Business on the corresponding Interest Payment Date, a Holder
of such Securities at the Close of Business, on such Record Date will receive the interest payable on such Securities on the corresponding Interest Payment Date notwithstanding the conversion of those Securities prior to that Interest Payment Date;
provided, however, that each Holder agrees, by accepting a Security, that if the Holder surrenders any Securities for conversion during such period, such Holder must pay the Company at the time such Holder surrenders its Securities for
conversion interest (including Additional Interest) in accordance with the next sentence if such conversion occurs after April 15, 2011. Securities surrendered for conversion during the period from the Close of Business on any 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 (including Additional Interest, if any) payable on such Interest Payment Date on the Securities so converted;
provided that no such payment need be made (a) if the Company has specified a Fundamental Change Repurchase Date in respect of the Securities that is after the Close of Business on a Record Date and on or prior to the Open of Business on
the next Interest Payment Date; (b) in respect of any conversion that occurs after the Close of Business on April 1, 2015 and prior to the Maturity Date or (c) to the extent of any overdue interest, if any such amount exists at the
time of conversion with respect to such Security. 
 ARTICLE 5 
 COVENANTS 
 Section 5.01. Payment of Securities. The
Company shall promptly make all payments in respect of the Securities on the dates and in the manner provided in the Securities and this First Supplemental Indenture, including payments of Cash and shares of Common Stock due upon conversion. The

 Each installment of accrued and unpaid interest and Additional Interest, if any, on the Securities due on any Interest Payment Date may be paid by
mailing checks for the amount payable to or upon the written order of the Securityholders entitled thereto as they shall appear on the registry books of the Company, provided that, with respect to any Securityholder with an aggregate
principal amount in excess of $2,000,000, at the application of such Holder in writing to the Registrar not later than the relevant Record Date accrued and unpaid interest and Additional Interest, if any, on such Holder’s Securities shall be
paid by wire transfer in immediately available funds to such Holder’s account in the United States supplied by such Holder from time to time to the Trustee and Paying Agent (if different from Trustee); provided further that payment of
accrued and unpaid interest and Additional Interest, if any, shall be made to the Depositary by wire transfer in immediately available funds in accordance with such wire transfer instructions and other procedures provided by the Depositary from time
to time. 
 Section 5.02. Reports and Certain Information. The Company shall file with the Trustee, within 15 days after it is
required to file them with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, copies of its annual report and the information, documents and other reports which the Company is required to file with the SEC pursuant to Section 13
or 15(d) of the Exchange Act; provided that any such reports, information or documents filed with the SEC pursuant to its Electronic Date Gathering, Analysis and Retrieval (or EDGAR) system shall be deemed filed with the Trustee and
provided further that the Company shall not be required to deliver to the Trustee any material for which the Company has sought and received confidential treatment from the SEC. The Company shall comply with the provisions of TIA
Section 314(a), whether or not the Company is required to file reports with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. Notwithstanding anything to the contrary herein, the Trustee shall have no duty to review such
documents for purposes of determining compliance with any provisions of this First Supplemental Indenture or any applicable law. 
 Section 5.03. Compliance Certificates. The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, an Officers’ Certificate signed by the
principal executive officer, principal financial officer or principal accounting officer of the Company and at least one other Officer of the Company, as to his or her knowledge of the Company’s compliance with all terms, conditions and
covenants under this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Company shall be in default, specifying all such defaults and the nature and status thereof of which he or she may have
knowledge. 
 Section 5.04. Stay, Extension and Usury Laws. The Company covenants, to the extent it may lawfully do so, that it
shall not at any time insist upon, plead or in any manner whatsoever claim or take the benefit or advantage of any stay, extension or usury law or other law which would prohibit or forgive the Company from paying all or any portion of the principal
amount or Fundamental Change Repurchase Price in respect of Securities, or any interest (including any Additional Interest) or Early Conversion Make-Whole Amount on the Securities as contemplated herein, wherever enacted, now or at any time
hereafter in force, or which may affect the covenants or the performance of the Indenture, and the Company, to the extent it may lawfully do so, hereby expressly waives all benefit or advantage of any such law and covenants, to the extent it may
lawfully do so, that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to 

  

 30 

 
the Trustee or any Agent, but shall suffer and permit the execution of every such power as though no such law had been enacted. 
 Section 5.05. Notice of Default. In the event that any Default or Event of Default shall occur, the Company shall give prompt (and in any
event within thirty (30) days after the Company becomes aware of such Default or Event of Default) written notice by an Officers’ Certificate of such Default or Event of Default, and any remedial action proposed to be taken, to the
Trustee.

Underwriting Agreement, the Company shall deposit a portion of the net proceeds from the sale of Securities in the Escrow Account pursuant to the Pledge and Escrow Agreement.  
 ARTICLE 6 
 CONSOLIDATION, MERGER,
CONVEYANCE, TRANSFER OR LEASE 
 Section 6.01. Company May
Consolidate, etc., Only on Certain Terms. Article 8 of the Original Indenture shall not apply to the Securities. The Company shall not consolidate with, or merge into, any other Person or convey, transfer or lease all or substantially all of the
Company’s properties and assets to any other Person in a single transaction or series of transactions, unless: 
  

	 	(a)	either: 

  

	 	•	 	 the resulting, continuing, surviving or transferee Person is the Company; or 

  

	 	•	 	 the resulting, continuing, surviving or transferee Person is a corporation or limited liability company (provided, that the successor may be a limited
liability company only if the Securities remain convertible into common stock of a corporation) organized and validly existing under the laws of the United States of America, any State thereof or the District of Columbia and shall expressly assume,
by an indenture supplemental hereto, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, all of the obligations of the Company under the Securities and the Indenture; 

 (b) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing; 
 (c) if, as a result of such transaction, the Securities become convertible into Common Stock or other securities issued by a third party, such third
party fully and unconditionally guarantees all obligations of the Company, or such other Person under the Securities and the Indenture; and 
 (d) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel (upon which the Trustee may conclusively rely), each stating that such consolidation, merger, conveyance, transfer or lease and, if a

 Section 6.02. Successor Substituted. Upon any consolidation of the Company with, or merger of
the Company into, any other Person or any conveyance, transfer or lease of all or substantially all of the properties and assets of the Company in accordance with Section 6.01 hereof, the successor Person formed by such consolidation or into
which the Company is merged or to which such conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under the Indenture with the same effect as if such successor Person
had been named as the Company herein, and thereafter, except in the case of a lease, the predecessor Person shall be relieved of all obligations and covenants under the Indenture and the Securities. 
 ARTICLE 7 
 DEFAULT
AND REMEDIES 
 Section 7.01. Events of Default. An “Event of Default” shall
occur if: 
 (a) the Company defaults in the payment of any principal of the Securities when the same becomes due and payable (whether at
maturity, on a Fundamental Change Repurchase Date or otherwise); 
 (b) the Company defaults in the payment of any accrued and unpaid
interest (including Additional Interest, if any) on any of the Securities within ten Business Days of an Interest Payment Date through, and including, April 15, 2011; 
 (c) the Company defaults in the payment of any accrued and unpaid interest (including Additional Interest, if any) on the Securities, to the extent such
accrued and unpaid interest (including Additional Interest, if any) is not covered under clause (b) above, when the same becomes due and payable, and such default continues for a period of 30 days; 
 (d) the Company fails to deliver all shares of Common Stock when such Common Stock is required to be delivered upon conversion of any Securities, and
such default continues for ten Business Days; 
 (e) the Company fails to provide the Fundamental Change Company Notice when required by
this First Supplemental Indenture and such default continues for ten Business Days; 
 (f) the Company fails to deliver any Early Conversion
Make-Whole Amount and such default continues for ten Business Days; 
 (g) the Company fails to comply with any of its other agreements
contained in the Securities or in the Indenture (other than a covenant or warranty or default whose performance or breach is elsewhere in this Section 7.01 specifically provided for) and such failure continues for 60 days after receipt by the
Company of a Notice of Default; 
 (h) the Company, or any Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law,
commences a voluntary case or proceeding; consents to the entry of an order for relief against it in an involuntary case or proceeding or the commencement of any case against it; consents to the appointment of a Custodian of it or for any
substantial part of its property; or makes a general assignment for the benefit of its creditors; 
 (i) a court of competent jurisdiction
enters an order or decree under any Bankruptcy Law that is for relief against the Company or a Significant Subsidiary in an involuntary case or proceeding; appoints a Custodian of the Company or a Significant Subsidiary for any substantial part of
the property of the Company or such Significant Subsidiary; or orders the winding up or liquidation of the Company or a Significant 

  

 32 

 
Subsidiary; and in each case of this clause (i) the order or decree remains unstayed and in effect for 60 consecutive days; or 
 (j) the Pledge and Escrow Agreement ceases to be in full force and effect, or enforceable, prior to its expiration in accordance with its terms.

 The term “Bankruptcy Law” means Title 11 of the United States Code (or any successor thereto) or any similar federal
or state law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator, sequestrator or similar official under any Bankruptcy Law. 
 A default under clause (g) above is not an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% in aggregate
principal amount of the Securities then outstanding notify the Company and the Trustee, in writing of the Default, and the Company does not cure the Default (or such Default is not waived) within the time period specified in clause (g) above,
as applicable, after actual receipt of such notice. The notice given pursuant to this Section 7.01 must be in writing, specify the Default, demand that it be remedied and state that the notice is a “Notice of Default.” When any
Default under this Section 7.01 is cured in accordance herewith, it shall cease to be a Default. 
 The Trustee shall not be charged
with knowledge of any Event of Default unless written notice thereof shall have been given to a Trust Officer at the Corporate Trust Office of the Trustee by the Company (including, without limitation, pursuant to Section 5.03), a Paying Agent,
any Holder or any agent of any Holder, which notice references the Securities and the Indenture. 
 Section 7.02. Acceleration.
If an Event of Default (other than an Event of Default with respect to the Company specified in clauses (h) or (i) of Section 7.01 hereof) occurs and is continuing, the Trustee may, by notice to the Company, or the Holders of at
least 25% in aggregate principal amount of the Securities then outstanding may, by notice to the Company and the Trustee, declare all unpaid principal of, plus interest (including Additional Interest, if any) accrued and unpaid through the date of
such declaration on, all the Securities then outstanding to be due and payable upon any such declaration, and the same shall thereupon become and be immediately due and payable. 
 If an Event of Default with respect to the Company specified in clauses (h) or (i) of Section 7.01 hereof occurs, all unpaid principal of,
plus interest (including Additional Interest, if any) accrued and unpaid through the date of such default on, all the Securities then outstanding shall ipso facto become and be immediately due and payable without any declaration or other act on the
part of the Trustee or any Holder. 
 The Holders of a majority in aggregate principal amount of the Securities then outstanding or the
Holders originally causing the acceleration by notice to the Trustee may rescind an acceleration of Securities and its consequences before a judgment or decree for the payment of money has been obtained by the Trustee if (a) the rescission
would not conflict with any existing order or decree, (b) all existing Events of Default, other than the nonpayment of the principal of, plus accrued and unpaid interest (including Additional Interest, if any) on, the Securities that has become
due solely by such declaration of acceleration, have been cured or waived and (c) all payments due to the Trustee and any predecessor Trustee under Section 6.7 of the Original Indenture have been made. No such rescission shall affect any
subsequent Default or impair any right consequent thereto. 
 The provisions of Sections 7.01 and 7.02 of this First Supplemental Indenture
shall supersede and replace the provisions, respectively, of Sections 5.1 and 5.2 of the Original Indenture for purposes of the Securities. 
 Section 7.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated to, pursue any available remedy by proceeding at law or in equity to collect the payment 

  

 33 

 
of the principal of or accrued and unpaid interest on the Securities, the payment of Cash and, if applicable, shares of Common Stock upon conversion or to
enforce the performance of any provision of the Securities or the Indenture. 
 The Trustee may maintain a proceeding even if it does not
possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law. 
 Notwithstanding anything to the contrary in the Indenture, to the extent elected by the Company, the sole remedy for an Event of Default relating to the
Company’s failure to comply with the covenant set forth in Section 5.02 hereof, for the failure to file any documents or reports that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act or
for any failure to comply with the requirements of Section 314(a)(1) of the TIA (any such obligation, the “Reporting Obligations”), shall for the first 90 days after the occurrence of such an Event of Default consist
exclusively of the right to receive additional interest on the Securities at an annual rate of 0.25% of the principal amount of the Securities (the “Additional Interest”). If the Company so elects, such Additional Interest will
accrue on all outstanding Securities from, and including, the date on which an Event of Default relating to a failure to comply with the Reporting Obligations hereof first occurs to, but not including, the 91st day thereafter (or such earlier date
on which the Event of Default relating to the Reporting Obligations shall have been cured or waived). On such 91st day (or earlier, if such Event of Default is cured or waived prior to such 91st day), such Additional Interest will cease to accrue
and, if such Event of Default has not been cured or waived prior to such 91st day, the Securities will be subject to acceleration as provided above. The provisions set forth in this paragraph will not affect the rights of Holders of Securities in
the event of the occurrence of any other Event of Default. For the avoidance of doubt, the Additional Interest shall not begin accruing until the Company fails to comply with the Reporting Obligations for a period of 60 calendar days after written
notice of such failure is given to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the Securities then outstanding. In the event Company does not elect to pay the
Additional Interest in accordance with this paragraph, the Securities will be subject to acceleration as provided above. In order to elect to pay the Additional Interest as the sole remedy during the first 90 days after the occurrence of an Event of
Default relating to failure to comply with the Reporting Obligations, the Company must notify the Trustee and the Paying Agent of such election on or before the Close of Business on the date on which such Event of Default occurs. Upon the
Company’s failure to timely give such notice or pay the Additional Interest, the Securities will be subject to acceleration as provided above. 
 Section 7.04. Waiver of Defaults and Events of Default. Subject to Section 7.06 and Section 8.02 hereof, the Holders of a majority in aggregate principal amount of the Securities then outstanding by notice to the
Trustee may waive an existing or future Default or Event of Default and its consequences, except a Default or Event of Default in the payment of the principal of, or any interest (including Additional Interest, if any) on any Security, or the
payment of any applicable Fundamental Change Repurchase Price, or a failure by the Company to deliver shares of Common Stock (and Cash in lieu of any fractional shares) or any Early Conversion Make-Whole Amount upon conversion in accordance with
Article 4 or any Default or Event of Default in respect of any provision of the Indenture or the Securities that, under Section 8.02 hereof, cannot be modified or amended without the consent of the Holders of each outstanding Security. When a
Default or Event of Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right. This Section 7.04 shall be in lieu of Section 316(a)(1)(B) of the TIA and such
Section 316(a)(1)(B) is hereby expressly excluded from the Indenture, as permitted by the TIA. 
  

 34 

 Section 7.05. Limitations on Suits. The provisions of this Section 7.05 shall supersede
and replace the provision of Section 5.7 of the Original Indenture for purposes of the Securities. Subject to Section 7.06 hereof, a Holder of a Security may not pursue any remedy with respect to the Indenture or the Securities unless:

 (a) the Holder gives to the Trustee written notice of a continuing Event of Default; 
 (b) the Holders of at least 25% in aggregate principal amount of the then outstanding Securities make a written request to the Trustee to pursue the
remedy; 
 (c) such Holder or Holders offer to the Trustee security or indemnity reasonably satisfactory to the Trustee against any loss,
liability or expense; 
 (d) the Trustee does not comply with the request to pursue the remedy within 60 days after receipt of the notice,
request and the offer of security or indemnity; and 
 (e) no direction inconsistent with such written request has been given to the Trustee
during such 60-day period by the Holders of a majority in aggregate principal amount of the Securities then outstanding. 
 A Securityholder
may not use the Indenture to prejudice the rights of another Securityholder or to obtain a preference or priority over such other Securityholder. 
 Section 7.06. Rights of Holders to Receive Payment and to Convert. The provisions of this Section 7.06 shall supersede and replace the provision of Section 5.8 of the Original Indenture for purposes of the Securities.
Notwithstanding any other provision of the Indenture, the right of any Holder of a Security to receive payment in Cash of the principal amount, Fundamental Change Repurchase Price or interest (including Additional Interest, if any) on any Security,
on or after the respective due dates expressed in the Security and this First Supplemental Indenture, receive shares of Common Stock (and Cash in lieu of fractional shares) or the Early Conversion Make-Whole Amount upon conversion in accordance with
Article 4 and to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, is absolute and unconditional and shall not be impaired or affected without the consent of the Holder. 
 Section 7.07. Collection Suit by Trustee. The provisions of this Section 7.07 shall supersede and replace the provision of
Section 5.3 of the Original Indenture for purposes of the Securities. If an Event of Default in the payment of principal or interest (including Additional Interest, if any), Fundamental Change Repurchase Price or any Early Conversion Make-Whole
Amount specified in clauses (a), (b), (c) or (f) of Section 7.01 hereof occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or another obligor on the
Securities for the whole amount owing with respect to the Securities and the amounts provided for in Section 6.7 of the Original Indenture. 
 Section 7.08. Priorities. The provisions of this Section 7.08 shall supersede and replace the provision of Section 5.6 of the Original Indenture for purposes of the Securities. Any money or property collected by the
Trustee pursuant to this Article 7, and after an Event of Default, any money or other property distributable in respect of the Company’s obligations under the Indenture shall be paid out in the following order: 
 First, to the Trustee (including any predecessor Trustee) for amounts due under Section 6.7 of the Original Indenture; 
 Second, to Securityholders for amounts due and unpaid on the Securities for the principal amount, interest (including Additional Interest, if any), the
Fundamental Change Repurchase Price, amounts due upon conversion (including amounts resulting from a Make-Whole Fundamental Change or the Early Conversion 

  

 35 

 
Make-Whole Amount), as the case may be, ratably, without preference or priority of any kind, according to such amounts due and payable on the Securities; and

 Third, the balance, if any, to the Company. 
 The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 7.08. At least 15 days before such record date, the Trustee shall mail to each Holder and the Company a
notice that states the record date, the payment date and the amount to be paid. 
 Section 7.09. Expenses and Compensation of the
Trustee. Without limiting any rights available to the Trustee under applicable law, when the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 7.01(h) or Section 7.01(i) above, the
expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any applicable federal or state bankruptcy, insolvency or other similar law.

 ARTICLE 8 
 AMENDMENTS, SUPPLEMENTS AND WAIVERS 
 Section 8.01.
Without Consent of Holders. The Company and the Trustee may amend or supplement the Indenture or the Securities without notice to, or consent of, any Securityholder: 
 (a) to cure any ambiguity, omission, defect or inconsistency, to correct or supplement any provision herein which may be inconsistent with any other provision herein, or to make any other provisions with respect to
matters or questions arising under the Indenture which shall not be inconsistent with the provisions of the Indenture, provided that such action pursuant to this clause (a) shall not adversely affect the interests of the Holders in any
material respect; 
 (b) to provide for uncertificated Securities in addition to or in place of Certificated Securities;

 (l) to add to the covenants listed in Article 5 of this First Supplemental Indenture and Article 10 of the Original Indenture or Events of Default listed

 Section 8.02. With Consent of Holders. The Company and the Trustee may amend or supplement the Securities or the Indenture with the consent
of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding. Subject to Section 7.04 and Section 7.06 hereof, the Holders of at least a majority in aggregate principal amount of the Securities
then outstanding may, without notice to the Holders of Securities, waive compliance in any instance by the Company with any provision of the Securities or the Indenture or waive any past default under the Indenture and its consequences, except a
default in the payment of any amount due, or in the obligation to deliver Common Stock, with respect to any Security or in respect of any provision which under the Indenture cannot be modified or amended without the consent of the Holder of each
Security affected. However, notwithstanding the foregoing but subject to Section 8.03 hereof, without the consent of the Holders of each Security then outstanding, an amendment, supplement or waiver may not: 
 (a) change the stated maturity of the principal of or the payment date of any installment of interest (including Additional Interest, if any) on or with
respect to the Securities; 
 (b) reduce the principal amount of, the Fundamental Change Repurchase Price of, or the Conversion Rate (except

 (i) alter the manner of calculation or rate of accrual of interest or Additional Interest or Fundamental Change Repurchase Price or the Conversion Rate (except as permitted under Section 8.01(g) hereof) on any Security or extend the
time for payment of any such amount; or 
 (j) reduce the Early Conversion Make-Whole Amount or otherwise modify the provisions of
Section 4.10 hereof in a manner adverse to a Holder. 
 It shall not be necessary for the consent of the Holders under this
Section 8.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 
 After an amendment, supplement or waiver under Section 8.01 above or this Section 8.02 becomes effective, the Company shall mail to the Holders
affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement
or waiver. 
 The provisions of Sections Section 8.01 and Section 8.02 of this First Supplemental Indenture shall supersede and
replace the provisions, respectively, of Sections 9.01 and 9.02 of the Original Indenture for purposes of the Securities. 
 Section 8.03. Revocation and Effect of Consents. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion
of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to its Security or portion of a
Security if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective. 
 After any
amendment, supplement or waiver becomes effective, it shall bind every applicable Securityholder. 
 Section 8.04. Notation on or
Exchange of Securities. If an amendment, supplement or waiver changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security about
the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms.

 ARTICLE 9 
 SATISFACTION AND DISCHARGE 
 Section 9.01. Satisfaction and Discharge
of the Indenture. Article 4 of the Original Indenture shall not apply to the Securities. The Indenture shall cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of Securities herein expressly
provided for), and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of the Indenture, when:

Date, upon acceleration, with respect to any Fundamental Change Repurchase Date, upon conversion or otherwise and the Company deposits with the Paying Agent or Conversion Agent, as the case may be, Cash, Common Stock or other consideration, or a
combination thereof, as applicable hereunder, sufficient to pay on such date all amounts due and owing on all outstanding Securities on such date; 
 (b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and 
 (c) the Company has delivered
to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of the Indenture have been complied with. 
 Notwithstanding the satisfaction and discharge of the Indenture, the obligations of the Company to the Trustee under Section 6.7 of the Original
Indenture and, if money shall have been deposited with the Trustee pursuant to Section 9.01(a)(ii) above, the obligations of the Trustee under Section 9.02 below shall survive such satisfaction and discharge. 
 Notwithstanding anything herein to the contrary, Article 4, Article 9, Section 2.04, Section 2.05, Section 2.06, Section 2.07,
Section 5.01, Section 5.04 and Section 5.05 of this First Supplemental Indenture and Section 6.7 and Section 10.2 of the Original Indenture shall survive any discharge of the Indenture until such time as there are no
Securities outstanding. 
 Section 9.02. Repayment to the Company. This Section 9.02 shall supersede and replace the
provisions of the last paragraph of Section 10.3 of the Original Indenture for purposes of the Securities. The Trustee, the Paying Agent and the Conversion Agent shall return to the Company upon written request any Cash or securities held by
them for the payment of any amount with respect to the Securities that remains unclaimed for two years, subject to applicable unclaimed property law. After return to the Company, Holders entitled to the Cash or securities must look to the Company
for payment as general creditors unless an applicable abandoned property law designates another person and the Trustee, the Paying Agent and the Conversion Agent shall have no further liability to the Securityholders with respect to such Cash or
securities for that period commencing after the return thereof.

used to interpret this First Supplemental Indenture. 
 Section 10.04. Multiple Counterparts. The parties may sign multiple

respect of such calculations. In the absence of manifest error, such calculations shall be final and binding on all Holders. The Company or its agents shall provide a copy of such calculations to the Trustee as required hereunder, and the Trustee
shall be entitled to rely on the accuracy of any such calculation without independent verification.

 AIRTRAN HOLDINGS, INC. 
 5.50% CONVERTIBLE SENIOR NOTES DUE APRIL 15, 2015 
 This Security is one of a duly authorized issue of 5.50%
Convertible Senior Notes due April 15, 2015 (the “Securities”) of the Company issued under an Indenture, dated as of April 30, 2008 (the “Original Indenture”) as supplemented by the First Supplemental
Indenture dated as of April 30, 2008 (the “First Supplemental Indenture” and, the Original Indenture as supplemented by the First Supplemental Indenture, the “Indenture”), each between the Company and U.S. Bank
National Association, as trustee (the “Trustee”). The terms of the Security include those stated in the Indenture, those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the
“TIA”), and those set forth in this Security. This Security is subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of all such terms. To the extent permitted by applicable law, if any
provision of this Security conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. Capitalized terms used but not defined herein have the meanings assigned to them in the Indenture
unless otherwise indicated. 
  

	1.	Interest. 

 AirTran Holdings, Inc., a Nevada
corporation (the “Company”), promises to pay interest (including any Additional Interest) on the principal amount of this Security at the rate per annum shown above. The Company will pay interest (including any Additional Interest),
payable semi-annually in arrears, on April 15 and October 15 of each year, with the first payment to be made on October 15, 2008, subject to limited exceptions if the Securities are converted after April 15, 2011 and prior to the
relevant Interest Payment Date. Interest will be paid to the Holders of record on the Interest Payment Record Date. Interest on the Securities will accrue on the principal amount from, and including, the most recent date to which interest has been
paid or provided for or, if no interest has been paid, from, and including, April 30, 2008, in each case to, but excluding, the next Interest Payment Date or Maturity Date, as the case may be. Interest will be computed on the basis of a 360-day
year of twelve 30-day months. 
  

	2.	Method of Payment. 

 Payment of the principal of,
and interest (including any Additional Interest), the Fundamental Change Repurchase Price and any Early Conversion Make-Whole Amount on, the Securities shall be made at the office of the Paying Agent in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and private debts. The Holder must surrender this Security to a Paying Agent to collect payment of principal. Payment of interest on Certificated Securities shall be made by
check mailed to the address of the Person entitled thereto as such address appears in the Register; provided, however, that Holders with Securities in an aggregate principal amount in excess of $2.0 million shall be paid, in accordance
with Section 5.01 of the First Supplemental Indenture, by wire transfer of immediately available funds. Notwithstanding the foregoing, so long as the Securities are registered in the name of a Depositary or its nominee, all payments with
respect to the Securities shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. 
  

	3.	Paying Agent, Registrar, Conversion Agent. 

 Initially, the Trustee shall act as Paying Agent, Registrar and Conversion Agent. The Company or any Affiliate of the Company may act as Paying Agent, Registrar or Conversion Agent, subject to the terms of the Indenture. 
  

 5 

	4.	Indenture. 

 The Securities are general unsecured
obligations of the Company initially limited to $74,750,000. The Company may, without consent of the Securityholders, issue Additional Securities under the Indenture with the same terms (including placing a portion of the proceeds thereof in the
Escrow Account to secure any interest payments due on or before April 15, 2011) as the Securities in an unlimited aggregate principal amount. The Indenture does not limit other debt of the Company, secured or unsecured. 
  

	5.	Purchase by the Company Upon a Fundamental Change. 

 Subject to the terms and conditions set forth in Article 3 of the First Supplemental Indenture, each Holder shall have the option to require the Company to repurchase its Securities upon the occurrence of a Fundamental Change. 

 

	6.	Conversion. 

 Subject to the terms and conditions
set forth in Article 4 of the First Supplemental Indenture, a Holder of a Security may convert the principal amount of such Security into shares of Common Stock at any time prior to the Close of Business on the Business Day immediately preceding the
Maturity Date, at the Conversion Rate in effect on the Conversion Date; provided, however, that, if such Security is submitted or presented for repurchase pursuant to Article 3 of the First Supplemental Indenture, such conversion right
shall terminate at the Close of Business on the Fundamental Change Repurchase Date for such Security (unless the Company shall default in making the Fundamental Change Repurchase Price payment when due, in which case the conversion right shall
terminate at the Close of Business on the date such default is cured and such Security is repurchased). 
  

	7.	Denominations; Transfer; Exchange. 

 The Securities
are in registered form, without coupons, in denominations of $1,000 and integral multiples of $1,000. A Holder may register the transfer of or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and to pay certain taxes, assessments or other governmental charges that may be imposed in relation thereto by law or permitted by the Indenture. 
  

	8.	Persons Deemed Owners. 

 The registered Holder of a
Security may be treated as the owner of such Security for all purposes. 
  

	9.	Unclaimed Money or Securities. 

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

	10.	Amendment, Supplement and Waiver. 

 Subject to
certain exceptions, the Securities or the Indenture may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the Securities then 

  

 6 

 
outstanding, and, subject to certain exceptions, an existing or future Default or Event of Default with respect to the Securities and its consequences or
compliance with any provision of the Securities or the Indenture may be waived with the consent of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding. Subject to the terms of the Indenture, without
the consent of or notice to any Holder, the Company and the Trustee may amend or supplement the Indenture or the Securities to, among other things, cure any ambiguity, defect or inconsistency or make any change that does not adversely affect in any
material respect the interests under the Indenture of any Holder. 
  

	11.	Defaults and Remedies. 

 Subject to certain
exceptions set forth in the First Supplemental Indenture, if an Event of Default (excluding an Event of Default specified in Sections 7.01(h) or 7.01(i) of the First Supplemental Indenture with respect to the Company) occurs and is continuing, the
Trustee by notice to the Company or the Holders of at least twenty five percent (25%) in principal amount of the Securities then outstanding by notice to the Company and the Trustee may declare the Securities to be due and payable. Upon such
declaration, the principal of, and accrued and unpaid interest (including any Additional Interest) on, all Securities shall be due and payable immediately. If an Event of Default specified in Sections 7.01(h) or 7.01(i) of the First Supplemental
Indenture with respect to the Company occurs, the principal of, and accrued and unpaid interest on, all the Securities shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee
or any Holder. 
  

	12.	Trustee Dealings with the Company. 

 Subject to
certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its
Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not the Trustee. 
  

	13.	No Recourse Against Others. 

 No recourse under or
upon any obligation, covenant or agreement of the Company contained in the Indenture, or in this Security, or because of any indebtedness evidenced thereby or hereby, shall be had against any incorporator, as such, or against any past, present or
future employee, stockholder, officer or director, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any
assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the Securities by the Holders and as part of the consideration for the issuance of the Securities.

  

	14.	Authentication. 

 This Security shall not be valid
until the Trustee or an authenticating agent manually signs the certificate of authentication on the other side of this Security. 
  

	15.	Abbreviations. 

 Customary abbreviations may be

EXTENT PERMITTED BY APPLICABLE LAW, IF ANY PROVISION OF THIS SECURITY CONFLICTS WITH THE EXPRESS PROVISIONS OF THE INDENTURE, THE PROVISIONS OF THE INDENTURE SHALL GOVERN AND BE CONTROLLING. THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN

as escrow agent (the “Escrow Agent”). 
 RECITALS 
 The Company and the Trustee have entered into an Indenture, dated as of April 30, 2008 (the “Original Indenture”) between the
Company and the Trustee, as supplemented by the First Supplemental Indenture dated as of April 30, 2008 (the “First Supplemental Indenture”) between the Company and the Trustee (the Original Indenture, as supplemented by the
First Supplemental Indenture, the “Indenture”) pursuant to which the Company will issue up to $74,750,000 in aggregate principal amount of its 5.50% Convertible Senior Notes due 2015 (the “Notes”). 
 The Company desires to establish an escrow account with the Escrow Agent into which certain sums as fully described in Section 2(a) below will be,
simultaneously with the initial issuance of the Notes, deposited by the Company to be held by the Escrow Agent on behalf of the Trustee for the benefit of holders of the Notes and distributed in accordance with the terms and conditions set forth
herein, and the Escrow Agent is willing to establish such an account and to accept such funds in accordance with the terms hereinafter set forth. 
 Capitalized terms used but not defined herein shall have the meanings assigned to such terms in the Indenture. 
 AGREEMENT 

 NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows: 
 SECTION 1. Establishment of Escrow Account. The Escrow Agent shall establish on the date hereof and maintain
in the Trustee’s name a “securities account” (within the meaning of Article 8 of the Uniform Commercial Code of the State of New York as in effect from time to time (the “New York UCC”)) (the “Escrow
Account”) to which there shall be immediately credited and held amounts received by the Escrow Agent from the Company in accordance with Section 2 hereof. The funds credited to the Escrow Account shall be applied and disbursed only as
provided herein. The Escrow Agent shall segregate the funds credited to the Escrow Account from its other funds held as an agent or in trust. 

 
The Escrow Agent shall treat all property held by it in the Escrow Account (including any cash) as “financial assets” (as defined in
Section 8-l02(a)(9) of the New York UCC) in accordance with Section 8-501 (or successor section) of the New York UCC. 
 SECTION 2. Deposit To The Escrow Account; Investments. 
 (a) Deposit To The Escrow Account.  
 (i) Simultaneously with the original issuance of the Notes, the Company shall deliver to the Escrow Agent for deposit in the Escrow
Account an amount equal to $12,333,750 (the “Escrow Funds”). 
 (ii) All amounts to be deposited with the
Escrow Agent shall be transferred by wire transfer of immediately available funds to the following account:

 ABA No.:

 Account Name: # AIRTRAN PLEDGE AND ESCROW AGREEMENT 
 Attention: Boston Admin 
 (b) Promptly
following the deposit of any funds into the Escrow Account, the Escrow Agent shall invest such funds in the name of the Trustee in Government Securities, as instructed by the Company. For purposes of this Agreement, “Government
Securities” shall mean (i) noncallable direct obligations of, or noncallable obligations, the payment of principal of and interest on which are unconditionally guaranteed by the United States of America, in each case with a maturity of
three years or less; and (ii) holdings in any mutual fund or similar investment vehicle that holds only cash and securities of the types set forth in (i) above. Promptly following the deposit of any funds into the Escrow Account, the
Company shall provide written instructions to the Escrow Agent as to the specific Government Securities in which funds are to be invested and until such instructions are given by the Company, the Escrow Agent shall not invest such funds. All such
amounts shall remain so invested until the close of business on the Business Day prior to any withdrawal by the Escrow Agent pursuant to Section 4 hereof. The Escrow Agent shall not be liable for any losses resulting from any depreciation in
the market value of such investments. All Government Securities from time to time credited to the Escrow Account constituting a “security entitlement” as defined in Section 8-102(a)(17) of the New York UCC shall be held in the name of
the Trustee and in no event shall the Company be or be deemed to be the “entitlement holder” (as such term is defined in Section 8-102(a)(7) of the New York UCC) with respect thereto. 

 (c) In investing funds pursuant to the terms of this Agreement and liquidating any investments held in
escrow hereunder, the Escrow Agent may, at the Company’s election and to the extent permitted by law, purchase Government Securities (including for the purposes of this paragraph Government Securities as to which the Escrow Agent or an Escrow
Agent Affiliate (as defined below) is the issuer or guarantor) from, and sell Government Securities to, itself or any Escrow Agent Affiliate and purchase Government Securities underwritten by, or in which a market is made by, the Escrow Agent or an
Escrow Agent Affiliate. For the purposes hereof, an “Escrow Agent Affiliate” shall mean an entity that directly, or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, the
Escrow Agent. The Escrow Agent shall bear no expense in connection with any investment made or sold pursuant to this Agreement. Any such investment may be sold prior to maturity by the Escrow Agent in accordance with Section 4 of this Agreement
whenever necessary to make any distribution required by this Agreement. 
 SECTION 3. Security Interest. 
 (a) Pledge and Assignment. As security for the Secured Obligations (as defined below), the Company hereby irrevocably pledges, assigns and grants
to the Trustee, for the equal and ratable benefit of the Holders of the Notes, a first priority continuing security interest in, and control of, all of the Company’s right, title and interest in and to all of the following whether now owned or
existing or hereafter acquired or created (collectively, the “Collateral”): 
 (i) the Escrow Account, all
security entitlements from time to time carried in the Escrow Account, all assets from time to time held in the Escrow Account, including, without limitation, the Escrow Funds and all certificates and instruments, if any, from time to time,
representing or evidencing the Escrow Account or the Escrow Funds; 
 (ii) all investments of funds in the Escrow Account,
all of which shall constitute Government Securities, and whether held by or registered in the name of the Escrow Agent, all certificates and instruments, if any, from time to time representing or evidencing any such Government Securities and all
security entitlements to such Government Securities; 
 (iii) all promissory notes, certificates of deposit, deposit
accounts, checks and other instruments evidencing Government Securities from time to time hereafter delivered to or otherwise possessed by the Escrow Agent, for or on behalf of the Company, in substitution for or in addition to any or all of the
then existing Collateral; 

 (iv) all interest, dividends, cash, instruments, securities and other properties from
time to time received, receivable or otherwise distributed in respect of or in exchange for any or all of the then existing Collateral; and 
 (v) all proceeds of the foregoing. 
 The Trustee hereby appoints the Escrow Agent to act as
the Trustee’s agent, on behalf of the Holders of the Notes, for purposes of perfecting the foregoing pledge, assignment and security interest in the Collateral, and the Escrow Agent hereby accepts such appointment. Except as otherwise provided
herein, for so long as the foregoing pledge, assignment and security interest remains in effect, the Escrow Agent hereby waives any right of set off or banker’s lien that it, in its individual capacity or in its capacity as an agent for Persons
other than the Trustee and the Holders of the Notes, may have with respect to any or all of the Collateral. 
 (b) Secured
Obligations. This Agreement secures, to the extent set forth herein, the due and punctual payment and performance of all obligations of the Company, whether now or hereafter existing, under the Notes, the Indenture and this Agreement, including,
without limitation, interest and premium, if any, accrued on the Notes after the commencement of a bankruptcy, reorganization or similar proceeding involving the Company to the extent permitted by applicable law (collectively, the “Secured
Obligations”). 
 (c) Delivery of Collateral. All certificates or instruments, if any, representing or evidencing all or any
portion of the Collateral shall be held by the Escrow Agent on behalf of the Trustee pursuant hereto and shall be in suitable form for transfer by delivery, or shall be accompanied by duly executed instruments of transfer or assignments in blank,
all in form and substance reasonably satisfactory to the Trustee, and all in form and substance sufficient to convey a valid security interest in such Collateral to the Trustee. All securities in uncertificated or book-entry form and all security
entitlements, if any, in each case representing or evidencing the Collateral shall be registered in the name of the Trustee (or any of its nominees) as the registered owner thereof, by book-entry or as otherwise appropriate so as to properly
identify the interest of the Trustee therein. In addition, the Trustee shall have the right, at any time following the occurrence of an Event of Default, to transfer to or to register in the name of the Trustee or any of its nominees any or all
other Collateral. Except as otherwise provided herein, all Collateral shall be deposited and held in the Escrow Account. The Escrow Agent shall have the right at any time to exchange certificates or instruments representing or evidencing all or any
portion of the Collateral for certificates or instruments of smaller or larger denominations in the same aggregate amount. 

 (d) Maintaining the Escrow Account. So long as this Agreement is in full force and effect:

 (i) subject to the other terms and conditions of this Agreement, all Collateral held by the Escrow Agent pursuant to this
Agreement shall be held in the Escrow Account, which shall be subject to the exclusive dominion and control of the Trustee for the benefit of the Trustee and the equal and ratable benefit of the Holders of the Notes; 
 (ii) the Escrow Account and all Collateral from time to time therein shall remain segregated from all other funds or other property
otherwise held by the Trustee or the Escrow Agent, as applicable; 
 (iii) all amounts (including, without limitation, any
Escrow Funds or interest on or other proceeds of the Escrow Funds or any Government Securities held in the Escrow Account) shall remain on deposit in the Escrow Account until withdrawn in accordance with this Agreement; and 
 (iv) the Escrow Agent shall take all steps necessary to ensure that the Trustee is the holder or entitlement holder (as the case may be)
of all of the Collateral and that either the Trustee for the equal and ratable benefit of the Holders of the Notes or, to the extent required by applicable law, the Escrow Agent, for the benefit of the Trustee and the equal and ratable benefit of
the Holders of the Notes, is the holder or entitlement holder of all Government Securities and other uncertificated securities on the books of the applicable Federal Reserve Bank or other applicable securities intermediary. 
 (e) Further Assurances. Prior to, contemporaneously herewith, and at any time and from time to time hereafter, the Company shall, at the
Company’s expense, execute and deliver to the Trustee or its designee such other instruments and documents, and take all further action as the Trustee deems reasonably necessary or advisable or may reasonably request to confirm or perfect the
security interest of the Trustee granted or purported to be granted hereby or to enable the Trustee to exercise and enforce its rights and remedies hereunder with respect to any Collateral, and the Company shall take all necessary action to preserve
and protect the security interest created hereby as a first priority, perfected lien and encumbrance upon the Collateral. 
 SECTION 4. Distributions from Escrow Account. Funds (or Government Securities that are scheduled to mature or that can be liquidated on or before the date of the applicable Scheduled Interest Payment (as defined
below)) on deposit in the Escrow Account shall be withdrawn by the Escrow Agent and transferred only in accordance with this Section 4: 

 (a) Event of Default. 
 (i) For so long as an Event of Default has occurred and is continuing under the Indenture, no amounts shall be disbursed from the Escrow
Account, except as provided in Section 4(a)(ii) below. 
 (ii) If (A) any Event of Default has occurred and is
continuing under Section 5.1 of the Original Indenture or Section 7.01 of the First Supplemental Indenture, (B) any other Event of Default has occurred and is continuing that results in the acceleration of the payment of principal,
interest, premium, if any, pursuant to the terms of the Indenture, or (C) any material breach or violation of any representation, warranty or agreement contained in this Agreement has occurred: 
 (1) The Trustee may, without notice to the Company except as required by applicable law and at any time or from time to time, direct the
Escrow Agent to liquidate all Collateral and transfer all proceeds thereof to the Paying Agent to apply such funds in accordance with Sections 5.2 and 5.6 of the Original Indenture. 
 (2) The Trustee (and/or the Escrow Agent at its direction and on its behalf) may also, in addition to the other rights and remedies
provided for herein, exercise in respect of the Collateral all the rights and remedies of a secured party upon default under the New York UCC, and may also, without notice except as specified below, sell the Collateral or any part thereof in one or
more parcels at public or private sales, at any of the Trustee’s or the Escrow Agent’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Trustee may deem commercially reasonable. The Company
agrees that, to the extent notice of sale shall be required by law, at least ten (10) days’ notice to the Company of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable
notification. The Trustee and the Escrow Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Trustee (or the Escrow Agent on its behalf) may adjourn any public or private sale from time to
time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. 

 (3) Any cash held by the Escrow Agent as Collateral and all net cash proceeds received
by the Trustee or the Escrow Agent in respect of any sale or liquidation of, collection from, or other realization upon all or any part of the Collateral may, in the discretion of the Trustee, be held by the Trustee or the Escrow Agent as collateral
for, and then or at any time thereafter be applied (after payment of any costs and expenses incurred in connection with any sale, liquidation or disposition of or realization upon the Collateral and the payment of any amounts payable to the Trustee
or the Escrow Agent) in whole or in part by the Trustee for the equal and ratable benefit of the Holders of the Notes against all or any part of the Secured Obligations in such order as described in Section 5.6 of the Original Indenture.

 (b) Scheduled Interest Payments. 
 (i) Pursuant to the Notes and Section 5.01 of the First Supplemental Indenture, the Company is obligated to make payments of interest (each, a “Scheduled Interest Payment”) on the Notes on each
of October 15, 2008, April 15, 2009, October 15, 2009, April 15, 2010, October 15, 2010 and April 15, 2011 (each, a “Scheduled Interest Payment Date”). The Scheduled Interest
Payments due on the Notes shall be made from amounts held in the Escrow Account in accordance with the procedures set forth in Section 4(b)(ii) below; provided, however, that nothing herein shall be construed as limiting the
Company’s obligation to make all interest payments due on the Notes at the times and in the amounts required by the Notes, which obligation shall be absolute and unconditional. 
 (ii) If the Company determines that Government Securities held in the Escrow Account will have to be liquidated in order for a Scheduled
Interest Payment to be made, the Company shall, not later than five (5) Business Days prior to the applicable Scheduled Interest Payment Date, so notify the Escrow Agent and identify, in a written direction to the Escrow Agent, the particular
Government Securities to be liquidated. The Escrow Agent shall liquidate the Government Securities so identified such that the proceeds of such sale shall be received by the Escrow Agent not later than the Business Day immediately preceding the
applicable Scheduled Interest Payment Date. Unless otherwise instructed by the Trustee one (1) Business Day prior to the applicable Scheduled Interest Payment Date, not later than 10:00 a.m., New York time, on the applicable Scheduled Interest
Payment Date, the Escrow Agent shall debit the Escrow Account and credit to the account of the Trustee as set forth in 

 
Section 4(e)(ii) hereof funds necessary to provide for payment in full of the next Scheduled Interest Payment on the Notes. 
 (c) Early Conversion Make-Whole Amount. 
 (i) Upon notice from the Trustee that the Conversion Date for any Notes has occurred prior to April 15, 2011, the Escrow Agent shall liquidate a portion of the Collateral equal to the Allocable Collateral as of
such Conversion Date multiplied by the number of Notes in principal amount of $1,000 submitted for conversion, all as calculated by the Company and certified by the Company to the Trustee and Escrow Agent; provided that if any Notes
are converted after the close of business on a Record Date but prior to the next Interest Payment Date, any portion of the applicable Allocable Collateral relating to the pro rata amount of interest payable on such Notes on such Interest Payment
Date and maturing immediately prior to such Interest Payment Date shall not be liquidated and instead shall be released in accordance with Section 4(b) above. For purposes hereof, “Allocable Collateral” means the percentage of
the Collateral applicable to one Note, which shall be determined by the Company, as of any Conversion Date, by dividing $1,000 by the aggregate principal amount of Notes outstanding as of such Conversion Date (including any Notes converted as of
such Conversion Date) and multiplying such fraction by 100. 
 (ii) The Escrow Agent shall release the proceeds of the
liquidation of the Collateral described in Section 4(c)(i) above to the Trustee to the extent necessary to pay to the converting Holders as the Early Conversion Make-Whole Amount. 
 (d) Excess Escrow Funds. Subject to Section 9(b), if (x) in the course of funding the Escrow Account pursuant to Section 2(a)
hereof or otherwise, the Company either elects or is required to deposit in the Escrow Account funds in an amount greater than that which is required to fund the payment of the Scheduled Interest Payments (in order to permit the Escrow Agent to
purchase an amount of Government Securities equal to or greater than that which is required to fund the payment of all remaining Scheduled Interest Payments on the principal amount of Notes then outstanding, the amount of accrued but unpaid fees and
expenses under Section 9(b) or otherwise) or (y) the balance of the Escrow Account exceeds the sum of (1) the amount of all remaining Scheduled Interest Payments plus (2) the amount of accrued but unpaid fees and expenses
under Section 9(b) (any such excess amounts under clauses (x) and (y) being hereinafter referred to as “Excess Escrow Assets”), the Company may, upon at least five (5) Business Days’ prior written notice
(accompanied by a calculation of such excess amounts), direct the Escrow Agent, so long as no Event of Default has occurred and is continuing, to release to the Company (or at the direction of the Company, to 

 
release to a designated third party) from the Escrow Account an amount of funds or Government Securities (rounded downward, as necessary, to the nearest
minimum denomination of the relevant Government Securities) the sum of which (including the aggregate principal amount of such Government Securities) is less than or equal to the amount of the Excess Escrow Assets. Upon receipt of such notice, the
Escrow Agent shall pay over or transfer to the Company (or its designated third party, as the case may be) the requested amount or Government Securities. 
 (e) Funds Transfer. 
 (i) All funds distributed from the Escrow Account to the
Company shall be transferred by wire transfer of immediately available funds to the account set forth in Schedule I hereof, or such other account as the Company shall from time to time designate by written notice to the Escrow Agent and the Trustee
in accordance with Section 11(g) of this Agreement. 
 (ii) All funds distributed from the Escrow Account to the Trustee
for payment on the Notes shall be credited to the account set forth in Schedule II hereof , or such other account as the Trustee shall from time to time designate by written notice to the Escrow Agent and the Company in accordance with
Section 11(g) of this Agreement. 
 (f) Written Instructions; Certificates. The Company shall, upon request by the Escrow Agent,
execute and deliver to the Escrow Agent such additional written instructions and certificates hereunder as may be reasonably required by the Escrow Agent to give effect to this Section 4. 
 SECTION 5. Termination of Security Interest. Subject to Section 4(a) hereof, upon payment in full of the Scheduled Interest
Payments, the security interest evidenced by this Agreement in any Collateral remaining in the Escrow Account shall automatically terminate and be of no further force and effect and the Escrow Agent shall automatically and without further
instruction distribute the remaining Collateral, if any, to the Company. Furthermore, upon the release of any Collateral from the Escrow Account in accordance with the terms of this Agreement, whether upon release of such Collateral to Holders of
Notes as payment of interest on the Notes or pursuant to Sections 4(a) or 4(c) or to the Company pursuant to Section 4(d) or otherwise, the security interest evidenced by this Agreement in such Collateral so released shall automatically
terminate and be of no further force and effect. The Trustee and the Escrow Agent shall, upon request by the Company, execute and deliver to the Company such additional written instructions and certificates hereunder as may be reasonably required by
the Company to give effect to this Section 5. 

 SECTION 6. Attorneys-in-Fact. The Company hereby irrevocably appoints each of the
Trustee and the Escrow Agent as the Company’s attorney-in-fact, coupled with an interest, with full authority in the place and stead of the Company and in the name of the Company or otherwise, from time to time in the Trustee’s or the
Escrow Agent’s discretion to take any action and to execute any instrument that the Trustee or the Escrow Agent reasonably may deem necessary or advisable to accomplish the purposes of this Agreement, including, without limitation, to receive,
endorse and collect all instruments made payable to the Company representing any interest payment, dividend or other distribution in respect of the Collateral or any part thereof and to give full discharge for the same, and the expenses of the
Trustee and the Escrow Agent incurred in connection therewith shall be payable by the Company. 
 SECTION 7. Trustee or Escrow
Agent May Perform. Without limiting the authority granted under Section 6 hereof, if the Company fails to perform any agreement contained herein, the Trustee or the Escrow Agent may, but shall not be obligated to, itself perform, or cause

such costs, expenses and fees have been paid; provided, however, unless an Event of Default shall have occurred and be continuing, such lien shall attach only to the extent of accrued but unpaid costs, expenses and fees and shall be without
prejudice to the Company’s rights under Section 4(d) of this Agreement. 

 SECTION 10. Rights, Duties and Immunities of Escrow Agent. Acceptance by the Escrow
Agent of its duties under this Agreement is subject to the following terms and conditions, which all parties to this Agreement hereby agree shall govern and control the rights, duties and immunities of the Escrow Agent: 
 (a) The duties and obligations of the Escrow Agent shall be determined solely by the express provisions of this Agreement and the Escrow Agent shall not
be liable except for the performance of such duties and obligations as are specifically set out in this Agreement. The Escrow Agent shall not be required to inquire as to the performance or observation of any obligation, term or condition under any
agreement or arrangement between the Company and the Trustee, and, unless it has been notified in writing, shall not be charged with knowledge of any agreement or arrangement between the Company and the Trustee (other than the Indenture and the
transactions contemplated under the Indenture). The Escrow Agent is not a party to, and is not bound by, any agreement or other document out of which this Agreement may arise. The Escrow Agent shall be under no liability to any party hereto by
reason of any failure on the part of any party hereto (other than the Escrow Agent) or any maker, guarantor, endorser or other signatory of any document or any other person to perform such person’s obligations under any such document. The
Escrow Agent shall not be bound by any waiver, modification, termination or rescission of this Agreement or any of the terms hereof, unless evidenced by a writing delivered to the Escrow Agent signed by the proper party or parties and, if the duties
or rights of the Escrow Agent are affected, unless it shall give its prior written consent thereto. This Agreement shall not be deemed to create a fiduciary relationship between the parties hereto under state or federal law. 
 (b) The Escrow Agent shall not be responsible in any manner for the validity or sufficiency of this Agreement or of any property delivered hereunder or
whether, except for its bad faith, gross negligence or willful misconduct, the Collateral is, at any time, sufficient to make any Scheduled Interest Payment or otherwise satisfy the Secured Obligations, or for the value or collectibility of any
note, check or other instrument, if any, so delivered, or for any representations made or obligations assumed by any party other than the Escrow Agent. Nothing herein contained shall be deemed to obligate the Escrow Agent to deliver any cash,
instruments, documents or any other property referred to herein, unless the same shall have first been received by the Escrow Agent pursuant to this Agreement. 
 (c) The Company shall reimburse and indemnify the Escrow Agent for, and hold it harmless against, any loss, liability or expense, including but not limited to reasonable legal counsel fees, incurred without bad faith,
gross negligence or willful misconduct on the part of the Escrow Agent, arising out of or in conjunction with its acceptance of, or the performance of its duties and 

 
obligations under, this Agreement, as well as the costs and expenses of defending against any claim or liability arising out of or relating to this
Agreement. 
 (d) The Escrow Agent shall be fully protected in acting on and relying upon any written notice, direction, request, waiver,
consent, receipt or other paper or document which the Escrow Agent in good faith believes to have been signed and presented by the Company or the Trustee, as applicable. 
 (e) The Escrow Agent shall not be liable for any error of judgment, or for any act done or step taken or omitted by it in good faith or for any mistake in fact or law, or for anything which it may do or refrain from
doing in connection herewith, except its own bad faith, gross negligence or willful misconduct. 
 (f) The Escrow Agent may, but shall be
under no obligation to, (i) seek the advice of legal counsel or (ii) petition a court for a declaratory ruling or other form of instruction in the event of any dispute regarding this Agreement or the subject matter hereof or question as to
the construction of any of the provisions of this Agreement or its duties hereunder, and except for its own bad faith, gross negligence or willful misconduct it shall incur no liability and shall be fully protected in respect of any action taken,
omitted or suffered by it in good faith in accordance with the advice or opinion of such counsel or such declaratory ruling or court instruction. 
 (g) The parties hereto agree that if the Escrow Agent is notified by the Trustee, the Company or the Holders of the Notes of any dispute with respect to the payment, ownership or right of possession of the Escrow Account, the Escrow Agent
is authorized and directed to retain in its possession, without liability to anyone, except for its bad faith, willful misconduct or gross negligence, all or any part of the Escrow Account until such dispute shall have been settled either by mutual
agreement by the parties concerned or by the final order, decree or judgment of a court or other tribunal of competent jurisdiction in the United States of America. In the case of a mutual agreement, a notice executed by the parties to the dispute
or their authorized representatives shall have been delivered to the Escrow Agent setting forth the resolution of the dispute; and in the case of any judicial or similar order, decree or judgment, a copy of such order, decree or judgment, together
with an opinion of counsel as to the finality of such order, decree or judgment, shall have been delivered to the Escrow Agent. The Escrow Agent shall be under no duty whatsoever to institute, defend or partake in such proceedings. 
 (h) The agreements set forth in this Section 10 shall survive the resignation or removal of the Escrow Agent, the termination of this Agreement and
the payment of all amounts hereunder. 
 SECTION 11. Miscellaneous.  

 (a) Waiver. No waiver of any provision of this Agreement nor consent to any departure by any party
therefrom shall in any event be effective unless the same shall be in writing and signed by each of the non-breaching parties and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which
given. 
 (b) Severability. If, for any reason whatsoever, any one or more of the provisions of this Agreement shall be held or deemed
to be inoperative, unenforceable or invalid in a particular case or in all cases, such circumstances shall not have the effect of rendering any of the other provisions of this Agreement inoperative, unenforceable or invalid, and the inoperative,
unenforceable or invalid provision shall be construed as if it were written so as to effectuate, to the maximum extent possible, the parties’ intent. 
 (c) Binding Effect. This Agreement shall inure to and be binding upon the parties and their respective successors and permitted assigns; provided, however, that the Company may not assign its rights or
obligations hereunder without the express prior written consent of the Trustee. 
 (d) Choice of Law. The existence, validity,
construction, operation and effect of any and all terms and provisions of this Agreement shall be determined in accordance with and governed by the internal laws of the State of New York, including without limitation the New York UCC, without giving
effect to the conflicts of law principles of such State. The securities intermediary’s jurisdiction for purposes of Section 8-110 of the New York UCC shall be the State of New York. 
 (e) Entire Agreement. This Agreement, the Underwriting Agreement, the Notes and the Indenture contain the entire agreement among the parties with
respect to the subject matter hereof and supersede any and all prior agreements, understandings and commitments with respect thereto, whether oral or written; provided, however, that this Agreement is executed and accepted by the
Trustee and the Escrow Agent subject to all terms and conditions of its acceptance of the trust under the Indenture, as fully as if said terms and conditions were set forth at length herein. 
 (f) Amendments. This Agreement may be amended only by a writing signed by duly authorized representatives of all parties. The Trustee and the
Escrow Agent may execute an amendment to this Agreement only if the requisite consent of each of the Holders of the Notes required by Article 8 of the First Supplemental Indenture has been obtained, unless no such consent is required by such
Section 8.01 of the First Supplemental Indenture. 
 (g) Notices. All notices, requests, instructions, orders and other
communications required or permitted to be given or made under this Agreement 

 
to any party hereto shall be delivered in writing by hand delivery or overnight delivery, or shall be delivered by facsimile with machine confirmation of
