hereby and thereby have been duly and validly authorized by all necessary corporate action on the part of Realogy. This Agreement and the ABG Agreement have been duly and validly executed and delivered by Realogy and such agreements, together with
the TRA and the Separation Agreement, constitute valid and binding obligations of Realogy, enforceable against Realogy in accordance with their terms, except as such enforcement may be limited by general equitable principles or by applicable
bankruptcy, insolvency, fraudulent transfer, moratorium, or similar laws, legal requirements and judicial decisions from time to time in effect which affect creditors’ rights generally.

transactions contemplated hereby or thereby, will (a) conflict with or violate any provision of the Certificate of Incorporation or by-laws of Realogy, (b) require on the part of Realogy any notice to or filing with, or any permit,
authorization, consent or approval of, any Governmental Entity, (c) conflict with, result in a breach of, constitute (with or without due notice or lapse of time or both) a default under, result in the acceleration of obligations under, create

been released on or before Closing. 
 2.5 Contracts. Realogy has delivered to WEX a complete and accurate copy of the Separation
Agreement and any other agreements to which Realogy is a party or of which it has knowledge (including written summaries of any oral agreements) adversely affecting the rights of WEX under this Agreement. The provisions of the Separation Agreement
that relate to the matters contained in the ABG Agreement are legal, valid, binding on and enforceable against Realogy and in full force and effect to the extent not modified by the ABG Agreement and Realogy is not in material breach or in material
violation of, or material default under, any such provision, and no event has occurred, is pending or is threatened, which, after the giving of notice, with lapse of time, or otherwise, would constitute a breach or default by Realogy or any other
party under any such provision of the Separation Agreement in a manner adverse to WEX.

 7.3 Indemnification Claims. 
 (a) An Indemnified Party shall give written notification to the Indemnifying Party of the commencement of any Third Party Action. Such notification shall
be given within 20 days after receipt by the Indemnified Party of notice of such Third Party Action, and shall describe in reasonable detail (to the extent known by the Indemnified Party) the facts constituting the basis for such Third Party Action
and the amount of the claimed damages; provided, however, that no delay or failure on the part of the Indemnified Party in so notifying the Indemnifying Party shall relieve the Indemnifying Party of any liability or obligation
hereunder except to the extent of any damage or liability caused by or arising out of such failure. Within 20 days after delivery of such notification, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control
of the defense of such Third Party Action with its own counsel reasonably satisfactory to the Indemnified Party; provided that the Indemnifying Party may not assume control of the defense of any Third Party Action (x) involving action by
the Internal Revenue Service or any other taxing authority, but only if the Indemnified Party can reasonably demonstrate that the action involves a likelihood of loss to it that is equal to or greater than the indemnifiable claim, (y) involving
criminal liability or (z) if the Indemnifying Party is in bankruptcy. If the Indemnifying Party does not, or is not permitted under the terms hereof to, so assume control of the defense of a Third Party Action, the Indemnified Party shall
control such defense, provided, however, that if the Controlling Party is not the Indemnifying Party in the case of an action by the Internal Revenue Service or any other taxing authority, the Controlling Party shall: 
 (i) promptly deliver to the Indemnifying Party complete copies of all written notices, requests, or other information received from any taxing authority
or judicial or similar body that could result in a redetermination or other adjustment to any Tax item which could increase the liability of the Indemnified Party for any Tax for which the Indemnifying Party is or may be liable under this Agreement
(hereinafter a “Tax Indemnity Issue”); 
 (ii) not provide any documents or other information to any taxing authority or judicial
or similar body that relate to the Tax Indemnity Issue without the Indemnifying Party’s prior review: 
 (iii) not submit any written
response or other written work in respect of any Tax Indemnity Issue to any taxing authority or judicial or similar body without allowing the Indemnifying Party to review and revise such written response or other written work to the extent it
relates to any Tax Indemnity issue (with any disagreement as to the ultimate language used in any such written response or other written work to be resolved by the Controlling Party); 
 (iv) permit the Indemnifying Party and its representatives, at the Indemnifying Party’s sole expense, to participate fully in all conferences,
meetings, proceedings or judicial appearances with or before any taxing authority or judicial or similar body (whether in person or by telephone) the subject matter of which is or includes the Tax Indemnity Issue; 
 (v) consult in good faith with the Indemnifying Party with respect to all aspects of any action or position to be taken by the Controlling Party that
relates to any Tax Indemnity Issue and take the Indemnifying Party’s interests into account; 
  

 - 9 - 

 (vi) not adopt any position in any proceeding that compromises a Tax Indemnity Issue so as to gain any
advantage with respect to any other issue, including those which are the subject of the same or any related proceeding; and 
 (vii) not
make any settlement offer to any taxing authority or accept any settlement offer made by any taxing authority, in each case with respect to any proceeding that is related, in whole or in part, to any Tax Indemnity Issue without the prior written
consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed. 
 The Non-controlling Party may participate in
such defense at its own expense and the Controlling Party shall keep the Non-controlling Party advised of the status of such Third Party Action and the defense thereof and shall consider in good faith recommendations made by the Non-controlling
Party with respect thereto. The Non-controlling Party shall furnish the Controlling Party with such information as it may have with respect to such Third Party Action (including copies of any summons, complaint or other pleading which may have been
served on such party and any written claim, demand, invoice, billing or other document evidencing or asserting the same) and shall otherwise cooperate with and assist the Controlling Party in the defense of such Third Party Action. The fees and
expenses of counsel to the Indemnified Party with respect to a Third Party Action shall be considered Damages for purposes of this Agreement if (i) the Indemnified Party controls the defense of such Third Party Action pursuant to the terms of
this Section 7.3(a) (other than pursuant to clause (x) above, in which case the parties shall determine an equitable sharing of counsel costs to reflect the pro rata likelihood of loss referenced in clause (x) above) or (ii) the
Indemnifying Party assumes control of such defense, but the Indemnified Party is named in the Third Party Action and its counsel reasonably concludes that the Indemnifying Party and the Indemnified Party have actual conflicts of interest with
respect to such Third Party Action. The Indemnifying Party shall not agree to any settlement of, or the entry of any judgment arising from, any Third Party Action without the prior written consent of the Indemnified Party, which shall not be
unreasonably withheld, conditioned or delayed. The Indemnified Party shall not agree to any settlement of, or the entry of any judgment arising from, any such Third Party Action without the prior written consent of the Indemnifying Party, which
shall not be unreasonably withheld, conditioned or delayed. 
 (b) In order to seek indemnification under this Article VII, an Indemnified
Party shall deliver a Claim Notice to the Indemnifying Party. 
 (c) Within 20 days after delivery of a Claim Notice, the Indemnifying Party
shall deliver to the Indemnified Party a Response, in which the Indemnifying Party shall: (i) agree that the Indemnified Party is entitled to receive all of the Claimed Amount (in which case the Response shall be accompanied by a payment by the
Indemnifying Party to the Indemnified Party of the Claimed Amount, by check or by wire transfer), (ii) agree that the Indemnified Party is entitled to receive the Agreed Amount (in which case the Response shall be accompanied by a payment by

 (d) Notwithstanding the other provisions of this Section 7.3, if a third party asserts (other than
by means of a lawsuit) that an Indemnified Party is liable to such third party for a monetary or other obligation which may constitute or result in Damages for which such Indemnified Party may be entitled to indemnification pursuant to this
Article VII, and such Indemnified Party reasonably determines that it has a valid business reason to fulfill such obligation, then (i) such Indemnified Party shall be entitled to satisfy such obligation, without prior notice to or consent
from the Indemnifying Party, (ii) such Indemnified Party may subsequently make a claim for indemnification in accordance with the provisions of this Article VII, and (iii) such Indemnified Party shall be reimbursed, in accordance with
the provisions of this Article VII, for any such Damages for which it is entitled to indemnification pursuant to this Article VII (subject to the right of the Indemnifying Party to dispute the Indemnified Party’s entitlement to
indemnification, or the amount for which it is entitled to indemnification, under the terms of this Article VII). 
 7.4 Survival of
Representations and Warranties. All representations and warranties that are covered by the indemnification agreements in Section 7.1(a) and Section 7.2(a) shall survive the Closing for two years from the date of Closing. The rights to
indemnification set forth in this Article VII shall not be affected by (i) any investigation conducted by or on behalf of an Indemnified Party or any knowledge acquired (or capable of being acquired) by an Indemnified Party, whether before or
after the date of this Agreement or the Closing Date, with respect to the inaccuracy or noncompliance with any representation, warranty, covenant or obligation which is the subject of indemnification hereunder or (ii) any waiver by an
Indemnified Party of any closing condition. For the avoidance of doubt, the indemnification obligations set forth in Sections 7.1(b) through and including 7.1(f) and 7.2(b) through and including 7.2(c) shall survive until the expiration of all
applicable statutes of limitation, provided that the indemnification obligation set forth in Section 7.1(b) shall also expire earlier upon the receipt by WEX of the Private Letter Ruling.

 (a) Realogy’s
maximum obligation for Damages under Sections 7.1(a), (b), (c) and (d) shall equal $75,000,000.

signed by such Holders in person or by an agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is

 (e) If the Company shall solicit from the Holders
any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request,
demand, authorization, direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be
given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of outstanding Securities
have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the 

  

 7 

 
outstanding Securities shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date
shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date. 
 ARTICLE II. 
 THE SECURITIES 
 Section 2.1 Form and Dating. The Securities and the Trustee’s certificate of authentication shall be substantially in the form of
Exhibits A and B, which are a part of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule or usage (provided that any such notation, legend or endorsement required by usage is in a form
acceptable to the Company). 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. 
 (a) 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, redemptions, repurchases and conversions. 
 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 2.12 hereof
and shall be made on the records of the Trustee and the Depositary. 
 (b) Book-Entry Provisions. This Section 2.1(b) shall apply
only to Global Securities deposited with or on behalf of the Depositary. 
 The Company shall execute and the Trustee shall, in accordance
with this Section 2.1(b), authenticate and deliver initially one or more Global Securities that (i) shall be registered in the name of the Depositary, (ii) shall be delivered by the Trustee to the Depositary or pursuant to the
Depositary’s instructions and (iii) shall be substantially in the form of Exhibit A attached hereto. 
  

 8 

 (c) Certificated Securities. Securities not issued as interests in the Global Securities will be
issued in certificated form substantially in the form of Exhibit B attached hereto. 
 Section 2.2 Execution and Authentication.
The Securities shall be executed on behalf of the Company by any Officer. The signature of the Officer on the Securities may be manual or facsimile. 
 Securities bearing the manual or facsimile signatures of individuals who were, at the time of the execution of the Securities, Officers shall bind the Company, notwithstanding that such individuals or any of them have
ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of authentication of such Securities. 
 No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for
herein duly executed by the Trustee by manual signature of an authorized signatory, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder.

 The Trustee shall authenticate and deliver the Securities for original issue in an aggregate principal amount of $20,783,000 upon one or
more Company Orders without any further action by the Company (other than as contemplated in Section 10.4 and Section 10.5 hereof). The aggregate principal amount of the Securities due at the Stated Maturity thereof outstanding at any time
may not exceed the amount set forth in the foregoing sentence. 
 The Securities shall initially be issued only in the form of one or more
Global Securities in definitive, fully-registered form without coupons and only in denominations of $1,000 of principal amount and any integral multiple of $1,000. 
 Section 2.3 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 where Securities may be presented for purchase or payment (“Paying Agent”) and an office or agency where Securities may be presented for conversion (“Conversion
Agent”). The Registrar shall keep a register of the Securities 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
Paying Agent includes any additional paying agent, including any named pursuant to Section 4.5. The term Conversion Agent includes any additional conversion agent, including any named pursuant to Section 4.5. 
 The Company shall enter into an appropriate agency agreement with any Registrar, Paying Agent, Conversion Agent or co-registrar (in each case, if such
Registrar, agent or co-registrar is a Person other than the Trustee). The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent. If the
Company fails to maintain a Registrar, Paying Agent or Conversion Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.7. The Company or any Subsidiary or an Affiliate of either
of them may act as Paying Agent, Registrar, Conversion Agent or co-registrar. 
  

 9 

 The Company initially appoints the Trustee as Registrar, Paying Agent and Conversion Agent in connection
with the Securities. 
 Section 2.4 Paying Agent to Hold Money and Securities in Trust. Except as otherwise provided herein, on
or prior to 10:00 a.m., New York City time, on each due date of payments in respect of any Security, the Company shall deposit with the Paying Agent a sum of money (in immediately available funds if deposited on the due date) sufficient to make such
payments when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Securityholders or the Trustee all money held by the Paying Agent
for the making of payments in respect of the Securities and shall notify the Trustee of any default by the Company in making any such payment. At any time during the continuance of any such default, the Paying Agent shall, upon the written request
of the Trustee, forthwith pay to the Trustee all money so held in trust. If the Company, a Subsidiary or an Affiliate of either of them acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust
fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds and Common Stock disbursed by it. Upon doing so, the Paying Agent shall have no further liability for the money.

 Section 2.5 Securityholder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent
list available to it of the names and addresses of Securityholders. If the Trustee is not the Registrar, the Company shall cause to be furnished to the Trustee at least semiannually on April 1 and October 1 a listing of Securityholders
dated within 15 days of the date on which the list is furnished and at such other times as the Trustee may request in writing a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of
Securityholders. 
 Section 2.6 Transfer and Exchange. 
 (a) Subject to Section 2.12, upon surrender for registration of transfer of any Security, together with a written instrument of transfer satisfactory
to the Registrar duly executed by the Securityholder or such Securityholder’s attorney duly authorized in writing, at the office or agency of the Company designated as Registrar or co-registrar pursuant to Section 2.3, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of any authorized denomination or denominations, of a like aggregate principal amount. The Company shall not
charge a service charge for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to pay all taxes, assessments or other governmental charges that may be imposed in connection with the transfer or exchange
of the Securities from the Securityholder requesting such transfer or exchange. 
 At the option of the Holder, Securities may be exchanged
for other Securities of any authorized denomination or denominations, of a like aggregate principal amount upon surrender of the Securities to be exchanged, together with a written instrument of transfer satisfactory to the Registrar duly executed
by the Securityholder or such Securityholder’s attorney duly authorized in writing, at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver,
the Securities which the Holder making the exchange is entitled to receive. 
  

 10 

 The Company shall not be required to make, and the Registrar need not register, transfers or exchanges of
Securities selected for redemption in whole or in part (except, in the case of Securities to be redeemed in part, the portion thereof not to be redeemed) or any Securities in respect of which a Fundamental Change Purchase Notice has been given and
not withdrawn by the Holder thereof in accordance with the terms of this Indenture (except, in the case of Securities to be purchased in part, the portion thereof not to be purchased) or to issue any Securities, register the transfer of, or exchange
any Securities for a period of 15 days before the Redemption Date. 
 (b) Notwithstanding any provision to the contrary herein, so long as a
Global Security remains outstanding and is held by or on behalf of the Depositary, (i) transfers of beneficial interests in a Global Security, in whole or in part, may be effected only through a book entry system maintained by the Holder of
such Global Security (or its agent) in accordance with Applicable Procedures, (ii) ownership of a beneficial interest in the Security shall be required to be reflected in book entry and (iii) transfers of Global Securities or beneficial
interests in Global Securities shall be made only in accordance with Section 2.12 and this Section 2.6(b). Transfers of a Global Security shall be limited to transfers of such Global Security in whole or in part, to the Depositary, to
nominees of the Depositary or to a successor of the Depositary or such successor’s nominee. 
 (c) Successive registrations and
registrations of transfers and exchanges as aforesaid may be made from time to time as desired, and each such registration shall be noted on the register for the Securities. 
 (d) Any Registrar appointed pursuant to Section 2.3 shall provide to the Trustee such information as the Trustee may reasonably require in
connection with the delivery by such Registrar of Securities upon transfer or exchange of Securities. 
 (e) No Registrar shall be required
to make registrations of transfer or exchange of Securities during any periods designated in the text of the Securities or in this Indenture as periods during which such registration of transfers and exchanges need not be made.

 Section 2.7 Replacement Securities. If (a) any mutilated Security is surrendered to the
Trustee, or (b) the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company and the Trustee such security or indemnity as may be required by them to
save each of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and upon its written request the Trustee shall 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 certificate 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 is about to be purchased by the
Company pursuant to Article III hereof, the Company in its discretion may, instead of issuing a new Security, pay or purchase such Security, as the case may be. 
 Upon the issuance of any new Securities under this Section 2.7, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and
any other expenses (including the fees and expenses of the Trustee) connected therewith. 
 Every new Security issued pursuant to this
Section 2.7 in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by
anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder. 
 The provisions of this Section 2.7 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen
Securities. 
  

 12 

 Section 2.8 Outstanding Securities; Determinations of Holders’ Action. Securities
outstanding at any time are all the Securities authenticated by the Trustee except for those cancelled by it, those paid pursuant to Section 2.7, those delivered to it for cancellation or surrendered for transfer or exchange and those described
in this Section 2.8 as not outstanding. A Security does not cease to be outstanding because the Company or an Affiliate thereof holds the Security; provided, however, that in determining whether the Holders of the requisite principal amount of
Securities have given or concurred in any request, demand, authorization, direction, notice, consent, waiver, or other Act hereunder, Securities owned by the Company or any other obligor upon the Securities or any Affiliate of the Company or such
other obligor shall be disregarded and deemed not to be outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such request, demand, authorization, direction, notice, consent, waiver or other Act, only
Securities which a Responsible Officer of the Trustee actually knows to be so owned shall be so disregarded. Subject to the foregoing, only Securities outstanding at the time of such determination shall be considered in any such determination
(including, without limitation, determinations pursuant to Articles VI and VIII hereof). 
 If a Security is replaced pursuant to
Section 2.7, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser. 
 If the Paying Agent holds, in accordance with this Indenture, on a Redemption Date, or on the Business Day following a Fundamental Change Purchase Date, or on Stated Maturity, money sufficient to pay Securities
payable on that date, then immediately after such Redemption Date, Fundamental Change Purchase Date or Stated Maturity, as the case may be, such Securities shall cease to be outstanding and interest on such Securities shall cease to accrue;
provided, that if such Securities are to be redeemed, notice of such redemption has been duly given pursuant to this Indenture or provision therefor satisfactory to the Trustee has been made. 
 If a Security is converted in accordance with Article IX, then from and after the time of conversion on the date of conversion, such Security shall cease
to be outstanding and interest shall cease to accrue on such Security. 
 Section 2.9 Temporary Securities. Pending the
preparation of definitive Securities, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any
authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may
determine, as conclusively evidenced by their execution of such Securities. 
 If temporary Securities are issued, the Company will cause
definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary Securities shall be exchangeable for definitive Securities upon surrender of the temporary Securities at the office or
agency of the Company designated for such purpose pursuant to Section 2.3, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities, the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of definitive Securities of authorized denominations. Until so exchanged the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive
Securities. 
  

 13 

 Section 2.10 Cancellation. If the Company shall acquire any of the Securities, such
acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless the same are delivered to the Trustee for cancellation. All Securities surrendered for payment, purchase by the Company pursuant
to Article III, conversion, redemption or registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the
Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. The Company may not
issue new Securities to replace Securities it has paid or delivered to the Trustee for cancellation or that any Holder has converted pursuant to Article IX. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled
as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of by the Trustee in accordance with the Trustee’s customary procedure. 
 Section 2.11 Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any
agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of the Security or the payment of any Make-Whole Interest Payment,
Redemption Price or Fundamental Change Purchase Price in respect thereof, and interest thereon, for the purpose of conversion and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor
any agent of the Company or the Trustee shall be affected by notice to the contrary. 
 Section 2.12 Global Securities.
(a) Notwithstanding any other provisions of this Indenture or the Securities, (A) transfers of a Global Security, in whole or in part, shall be made only in accordance with Section 2.6 and Section 2.12(a)(i), (B) transfers
or exchanges of a beneficial interest in a Global Security for an interest in the same or another Global Security shall comply with Section 2.6 and Section 2.12(a)(ii) below, (C) transfers or exchanges of a beneficial interest in a
Global Security for a Certificated Security shall comply with Section 2.6, Section 2.12(a)(iii) below and Section 2.12(e)(i) below, and (D) transfers or exchanges of a Certificated Security shall comply with Section 2.6 and
Sections 2.12(a)(iv) and (a)(v) below. 
 (i) Transfer of Global Security. A Global Security may not be transferred, in whole or in part, to
any Person other than the Depositary or a nominee or any successor thereof, and no such transfer to any such other Person may be registered; provided that this clause (i) shall not prohibit any transfer of a Certificated Security that is issued
in exchange for a Global Security. No transfer of a Global Security to any Person shall be effective under this Indenture or the Securities unless and until such Security has been registered in the name of such Person. Nothing in this
Section 2.12(a)(i) shall prohibit or render ineffective any transfer of a beneficial interest in a Global Security effected in accordance with the other provisions of this Section 2.12. 
 (ii) Transfer or Exchange of a Beneficial Interest in a Global Security for a Beneficial Interest in the Same or Another Global Security. 
 (y) A beneficial interest in a Global Security may not be transferred or exchanged for a beneficial interest in another Global Security except upon
satisfaction of the 

  

 14 

 
following requirements set forth in this clause (y). Upon receipt by the Trustee of a request to transfer or exchange of a beneficial interest in a Global
Security in accordance with Applicable Procedures for a beneficial interest in another Global Security, together with written instructions to the Trustee to make, or direct the Registrar to make, in the case of a transfer or exchange of a beneficial
interest in a Global Security for a beneficial interest in another Global Security, an adjustment on its books and records with respect to such Global Securities to reflect a decrease and increase in the aggregate principal amount of the Securities
represented by such Global Securities, such instructions to contain information regarding the Depositary accounts to be credited with such decrease and increase, then the Trustee, (1) shall cause, or direct the Registrar to cause, in accordance
with the standing instructions and procedures existing between the Depositary and the Registrar, the aggregate principal amount of the Securities represented by the appropriate Global Security to be decreased by the aggregate principal amount that
the other Global Security is increased and (2) in accordance with the standing instructions and procedures existing between the Depositary and the Registrar and Applicable Procedures, shall debit and credit or cause to be debited or credited,
as appropriate, to the accounts of the persons specified in such instructions a beneficial interest in the Global Security or Global Securities, as appropriate, equal to the amount of the beneficial interests so transferred or exchanged. 

(z) Beneficial interests in a Global Security may be transferred to Persons who take delivery in the same Global Security in accordance with the
Applicable Procedures. No written orders or instructions shall be required to be delivered to the Registrar or the Trustee to effect the transactions described in this Section 2.12(a)(ii)(z). 
  

 15 

 (iii) Transfer or Exchange of a Beneficial Interest in a Global Security for a Certificated Security. A
beneficial interest in a Global Security may not be exchanged for a Certificated Security except upon satisfaction of the requirements set forth below and in Section 2.12(b)(1) below. Upon receipt by the Trustee of a transfer of a beneficial
interest in a Global Security in accordance with Applicable Procedures for a Certificated Security in the form satisfactory to the Trustee, together with written instructions to the Trustee to make, or direct the Registrar to make, an adjustment on
its books and records with respect to such Global Security to reflect a decrease in the aggregate principal amount of the Securities represented by the Global Security, such instructions to contain information regarding the Depositary account to be
credited with such decrease, then the Trustee shall cause, or direct the Registrar to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Registrar, the aggregate principal amount of the
Securities represented by the Global Security to be decreased by the aggregate principal amount of the Certificated Security to be issued, shall issue such Certificated Security and shall debit or cause to be debited to the account of the person
specified in such instructions a beneficial interest in the Global Security equal to the principal amount of the Certificated Security so issued. 
 (iv) Transfer and Exchange of Certificated Securities. When Certificated Securities are presented to the Registrar with a request: 
 (y) to register the transfer of such Certificated Securities; or 
 (z) to exchange such Certificated Securities for an equal
principal amount of Certificated Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided, however, that the
Certificated Securities surrendered for transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Registrar, duly executed by the Holder thereof or his
attorney duly authorized in writing 
  

 16 

 (v) Transfer of a Certificated Security for a Beneficial Interest in a Global Security. A Certificated
Security may not be exchanged for a beneficial interest in a Global Security except upon satisfaction of the requirements set forth below. 
 Upon receipt by the Trustee of a Certificated Security, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with written instructions directing the Trustee to make, or to direct
the Registrar to make, an adjustment on its books and records with respect to such Global Security to reflect an increase in the aggregate principal amount of the Securities represented by the Global Security, such instructions to contain
information regarding the Depositary account to be credited with such increase, then the Trustee shall cancel such Certificated Security and cause, or direct the Registrar to cause, in accordance with the standing instructions and procedures
existing between the Depositary and the Registrar, the aggregate principal amount of Securities represented by the Global Security to be increased by the aggregate principal amount of the Certificated Security to be exchanged, and shall credit or
cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Global Security equal to the principal amount of the Certificated Security so cancelled. If no Global Securities are then outstanding, the
Company shall issue and the Trustee shall authenticate, upon written order of the Company in the form of an Officers’ Certificate, a new Global Security in the appropriate principal amount. 
  

 17 

 (b) The provisions of clauses (1), (2), (3) and (4) below shall apply only to Global
Securities: 
 (1) Notwithstanding any other provisions of this Indenture or the Securities, a Global Security shall not be exchanged in
whole or in part for a Security registered in the name of any Person other than the Depositary or one or more nominees thereof, provided that a Global Security may be exchanged for Securities registered in the names of any Person designated by the
Depositary in the event that (i) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or such Depositary has ceased to be a “clearing agency” registered under the
Exchange Act and a successor Depositary is not appointed by the Company within 90 days or (ii) an Event of Default has occurred and is continuing with respect to the Securities. Any Global Security exchanged pursuant to clause (i) above
shall be so exchanged in whole and not in part, and any Global Security exchanged pursuant to clause (ii) above may be exchanged in whole or from time to time in part as directed by the Depositary. Any Security issued in exchange for a Global
Security or any portion thereof shall be a Global Security; provided that any such Security so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Security. 
 (2) Securities issued in exchange for a Global Security or any portion thereof shall be issued in definitive, fully registered form, without interest
coupons, shall have an aggregate principal amount equal to that of such Global Security or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear
the applicable legends provided for herein. Any Global Security to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Registrar. With regard to any Global Security to be exchanged in part, either such Global Security
shall be so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with respect to such Global Security, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so
exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Security issuable on such exchange to or upon the order of the Depositary or
an authorized representative thereof. 
  

 18 

 (3) Subject to the provisions of clause (5) below, the registered Holder may grant proxies and
otherwise authorize any Person, including Agent Members (as defined below) and Persons that may hold interests through Agent Members, to take any action which a holder is entitled to take under this Indenture or the Securities. 
 (4) In the event of the occurrence of any of the events specified in clause (1) above, the Company will promptly make available to the Trustee a
reasonable supply of Certificated Securities in definitive, fully registered form, without interest coupons. 
 (5) Neither any members of,
or participants in, the Depositary (collectively, the “Agent Members”) nor any other Persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Security registered in the name
of the Depositary or any nominee thereof, or under any such Global Security, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and
holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or
other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act, the operation of customary practices of such
Persons governing the exercise of the rights of a holder of any Security. 
 Section 2.13 CUSIP Numbers. The Company may issue
the Securities with one or more “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice may
state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the CUSIP numbers. 
 ARTICLE III. 
 REDEMPTION AND PURCHASES 
 Section 3.1 Company’s Right to Redeem; Notices to Trustee. Prior to May 1, 2011, the Securities will not be redeemable at the
Company’s option. Beginning on May 1, 2011, the Company, at its option, may redeem the Securities, subject to and in accordance with the terms and conditions of Section 5 of the Securities, for cash, as a whole or in part, at a redemption
price equal to the principal amount of those Securities, if the Sale Price of the Common Stock has exceeded 150% of the Conversion Price then in effect for at least 20 Trading Days in any period of 30 consecutive Trading Days ending on the Trading
Day prior to the mailing of the Redemption Notice. In addition, the Company will pay any accrued and unpaid interest on those Securities (including Securities which are converted into Common Stock under the circumstances specified in
Section 9.9) to the Redemption Date. If the Company elects to redeem Securities pursuant to Section 5 of the Securities, it shall notify the Trustee in writing of the Redemption Date, the principal amount of Securities to be redeemed and
the Redemption Price. 
  

 19 

 The Company shall give the notice to the Trustee of its intention to exercise its right to redeem the
Securities as provided for in this Section 3.1 by a Company Order at least ten (10) Business Days prior to the day the Redemption Notice is to be mailed. 
 Section 3.2 Selection of Securities to Be Redeemed. If less than all the Securities are to be redeemed, unless the procedures of the Depositary provide otherwise, the Trustee shall select the Securities to
be redeemed by lot, on a pro rata basis or by another method the Trustee considers fair and appropriate (so long as such method is not prohibited by the rules of any stock exchange on which the Securities are then listed). The Trustee shall make the
selection within five Business Days after it receives the notice provided for in Section 3.1 from outstanding Securities not previously called for redemption. The Trustee may select for redemption portions of the principal amount of Securities
that have denominations larger than $1,000. 
 Securities and portions of Securities that the Trustee selects shall be in principal amounts
of $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company promptly of the Securities or
portions of the Securities to be redeemed. 
 Securities and portions of Securities that are to be redeemed are convertible by the Holder
until the close of business on the second Business Day prior to the Redemption Date unless the Company fails to pay the Redemption Price on the Redemption Date. If any Security selected for partial redemption is converted in part before termination
of the conversion right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities which have been converted during a
selection of Securities to be redeemed may be treated by the Trustee as outstanding for the purpose of such selection. 
 Section 3.3
Notice of Redemption. At least 20 days but not more than 60 days before a Redemption Date, the Company shall mail a notice of redemption (the “Redemption Notice”) by first-class mail, postage prepaid, to each Holder of
Securities to be redeemed. 
 The notice shall identify the Securities to be redeemed and shall state: 
 (1) the Redemption Date; 
 (2) the
Redemption Price; 
 (3) the Conversion Price; 
 (4) the name and address of the Paying Agent and Conversion Agent; 
 (5) that Securities called for
redemption may be converted at any time before the close of business on the second Business Day prior to the Redemption Date; 
  

 20 

 (6) that Holders who wish to convert their Securities must satisfy the requirements set forth in
Section 8 of the Securities; 
 (7) that Securities called for redemption must be surrendered to the Paying Agent to collect the
Redemption Price; 
 (8) if fewer than all of the outstanding Securities are to be redeemed, the certificate numbers, if any, and principal
amounts of the particular Securities to be redeemed; 
 (9) that, unless the Company defaults in making payment of such Redemption Price,
interest on Securities called for redemption will cease to accrue interest on and after the Redemption Date; and 
 (10) the CUSIP number(s)
of the Securities. 
 At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at the
Company’s expense, provided that the Company makes such request at least ten Business Days prior to the date by which such notice of redemption is to be given to Holders in accordance with this Section 3.3, unless the Trustee agrees to a
shorter period. 
 Section 3.4 Effect of Notice of Redemption. Once notice of redemption is given, Securities called for
redemption become due and payable on the Redemption Date and at the Redemption Price stated in the notice except for Securities which are converted in accordance with the terms of this Indenture. Upon surrender to the Paying Agent, such Securities
shall be paid at the Redemption Price stated in the notice. 
 Section 3.5 Deposit of Redemption Price. Prior to 10:00 a.m., New
York City time, on the Redemption Date, the Company shall deposit with the Paying Agent (or if the Company or a Subsidiary or an Affiliate of either of them is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the
applicable Redemption Price of all Securities to be redeemed on that date other than Securities or portions of Securities called for redemption which on or prior thereto have been delivered by the Company to the Trustee for cancellation or have been
converted. The Paying Agent shall as promptly as practicable return to the Company any money not required for that purpose because of conversion of Securities pursuant to Article IX. If such money is then held by the Company in trust and is not
required for such purpose, it shall be discharged from such trust. 
 Section 3.6 Securities Redeemed in Part. Upon surrender of
a Certificated Security that is redeemed in part, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Certificated Security in an authorized denomination equal in principal amount to the unredeemed portion of
the Certificated Security surrendered. 
 Section 3.7 Purchase of Securities at Option of the Holder upon Fundamental Change.

 (a)(1) If a Fundamental Change occurs at any time prior to the Stated Maturity (subject to certain exceptions set forth below), the
Securities not previously purchased or redeemed by the Company shall be purchased by the Company for cash, at the option of the Holder thereof, at a purchase price specified in Section 6 of the Securities (the “Fundamental Change

  

 21 

 
Purchase Price”), as of the date that is between 30 and 60 days after the date of a notice of Fundamental Change delivered by the Company
pursuant to Section 3.7(b) (the “Fundamental Change Purchase Date”), subject to satisfaction by or on behalf of the Holder of the requirements set forth in Section 3.7(c). 
 A “Fundamental Change” will be deemed to have occurred at such time after the Securities are originally issued when any of the following
events shall occur: 
 (i) the acquisition by any Person, directly or indirectly, through a purchase, merger or other acquisition
transaction or series of purchases, mergers or other acquisition transactions of shares of the Capital Stock of the Company entitling that Person to exercise 50% or more of the total voting power of all shares of the Capital Stock of the Company
entitled to vote generally in elections of directors, other than any acquisition by the Company, any of its subsidiaries or any of its employee benefit plans; or 
 (ii) the first day on which a majority of the members of the board of directors of the Company does not consist of Continuing Directors; or 
 (iii) the Company consolidates or merges with or into any other Person, any merger of another Person into the Company, or any conveyance, transfer,
sale, lease or other disposition of all or substantially all of the Company’s properties and assets to another Person, 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 the holders of 50% or more of the total voting power of the Company’s Capital Stock entitled to vote generally in elections of directors
immediately prior to the transaction have the entitlement to exercise, directly or 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
Person immediately after giving effect to such transaction; and (B) any merger primarily 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 
 (iv) the termination of trading of the
Common Stock, which shall be deemed to have occurred if the Common Stock or other common stock into which the notes are convertible is neither listed for trading on a United States national securities exchange nor any United States system of
automated dissemination of quotations of securities prices or traded in over-the-counter securities markets, and no American Depositary Shares or similar instruments for such common stock are so listed or approved for listing in the United States.

 A “Continuing Director” shall mean, as of any date of determination, any member of the Board of Directors who:

 (i) was a member of the Board of Directors of the Company on the date hereof; or 
  

 22 

 (ii) was nominated for election, appointed or elected to the Board of Directors with the approval of a
majority of the Continuing Directors who were members of the Board of Directors at the time of the new director’s nomination, appointment or election, either by a specific vote or by approval of the proxy statement issued by the Company on
behalf of the Company’s entire board of directors in which such individual is named as a nominee for director. 
 (2) Notwithstanding
the provisions of Section 3.7(a)(1), the Company shall not be required to purchase the Securities of the Holders upon a Fundamental Change pursuant to this Section 3.7 (and a Fundamental Change shall be deemed not to have occurred) if:

 (i) the Sale Price per share of Common Stock for any five Trading Days within (1) the period of 10 consecutive Trading Days ending
immediately after the later of the Fundamental Change or the public announcement of the Fundamental Change, in the case of a Fundamental Change under clause (i) or (ii) of the definition of “Fundamental Change” above, or
(2) the period of 10 consecutive Trading Days ending immediately before the Fundamental Change, in the case of a Fundamental Change under clause (iii) or (iv) of the definition of “Fundamental Change” above, equals or
exceeds 110% of the Conversion Price of the Securities in effect on each of those five Trading Days (the “110% Trading Price Exception”); or 
 (ii) 90% or more 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 (i) or (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 national securities exchange, and, as a result of the transaction or transactions, the Securities become convertible solely into such Common Stock, depositary receipts or other certificates representing common equity interests (and
any rights attached thereto). 
 For the purposes of this Section 3.7, (x) whether a Person is a “beneficial owner” shall be
determined in accordance with Rule 13d-3 and Rule 13d-5 under the Exchange Act (except that any of those Persons shall be deemed to have beneficial ownership of all securities it has the right to acquire, whether the right is currently exercisable
or is exercisable only upon the occurrence of a subsequent condition) and (y) the term “Person” includes any syndicate or group that would be deemed to be a “person” under Section 13(d)(3) of the Exchange Act.

 (b) No later than 30 days after the occurrence of a Fundamental Change, the Company shall mail a written notice of the Fundamental Change
by first class mail to the Trustee and to each Holder (and to beneficial owners as required by applicable law). The notice shall include a form of Fundamental Change Purchase Notice to be completed by the Holder and shall state: 
 (1) briefly, the events causing a Fundamental Change and the date of such Fundamental Change; 
 (2) the date by which the Fundamental Change Purchase Notice pursuant to this Section 3.7 must be delivered to the Paying Agent in order for a
Holder to exercise the repurchase rights; 
  

 23 

 (3) the Fundamental Change Purchase Date; 
 (4) the Fundamental Change Purchase Price; 
 (5) the name and address of the Paying Agent and the Conversion Agent; 
 (6) the Conversion Price and any adjustments thereto;

 (7) that the Securities as to which a Fundamental Change Purchase Notice has been given may be converted if they are otherwise convertible
pursuant to Article IX hereof only if the Fundamental Change Purchase Notice has been withdrawn in accordance with the terms of this Indenture; 
 (8) that the Securities must be surrendered to the Paying Agent to collect payment; 
 (9) that the Fundamental Change Purchase
Price for any Security as to which a Fundamental Change Purchase Notice has been duly given and not withdrawn will be paid promptly following the later of the Fundamental Change Purchase Date and the time of surrender of such Security as described
in clause (8) above; 
 (10) briefly, the procedures the Holder must follow to exercise rights under this Section 3.7; 

(11) briefly, the conversion rights of the Securities; 
 (12) the procedures for withdrawing a Fundamental Change Purchase Notice; 
 (13) that, unless the Company
defaults in making payment of such Fundamental Change Purchase Price, interest, if any, on Securities surrendered for purchase by the Company will cease to accrue on and after the Fundamental Change Purchase Date; and 
 (14) the CUSIP number(s) of the Securities. 
 Without otherwise limiting the Company’s obligations pursuant to this Section 3.7 in any way, the Company shall also issue a press release through Dow Jones & Company, Inc. containing the relevant information and
otherwise make this information available on the Company’s web site or through another public medium as the Company may use at that time. 
 (c) A Holder may exercise its rights specified in Section 3.7(a) upon delivery of a written notice of purchase (a “Fundamental Change Purchase Notice”) to the Paying Agent at any time on or prior to the close of
business on the second Business Day preceding the Fundamental Change Purchase Date (unless the Company shall specify a later date), specifying: 
 (1) the certificate number of the Security, if certificated, which the Holder will deliver to be purchased or, if not certificated, the notice must comply with the appropriate depositary procedures; 
  

 24 

 (2) the portion of the principal amount of the Security which the Holder will deliver to be purchased,
which portion must be $1,000 or an integral multiple of $1,000; and 
 (3) that such Security shall be purchased pursuant to the terms and
conditions specified in Section 6 of the Securities and in this Indenture. 
 The delivery of such Security to the Paying Agent with the
Fundamental Change Purchase Notice (together with all necessary endorsements) at the offices of the Paying Agent shall be a condition to the receipt by the Holder of the Fundamental Change Purchase Price therefor; provided, however, that such
Fundamental Change Purchase Price shall be so paid pursuant to this Section 3.7 and Section 3.8 only if the Security so delivered to the Paying Agent shall conform in all respects to the description thereof set forth in the related
Fundamental Change Purchase Notice. 
 The Company shall purchase from the Holder thereof, pursuant to this Section 3.7 and
Section 3.8, 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 Indenture that apply to the purchase of all of a Security also apply to the purchase of such portion of
such Security. 
 Any purchase by the Company contemplated pursuant to the provisions of this Section 3.7 and Section 3.8 shall be
consummated by the delivery of the consideration to be received by the Holder. 
 Notwithstanding anything herein to the contrary, any Holder
delivering to the Paying Agent the Fundamental Change Purchase Notice contemplated by this Section 3.7(c) shall have the right to withdraw such Fundamental Change Purchase Notice, in whole or in part, at any time prior to the close of business
on the Fundamental Change Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.8. 
 The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Purchase Notice or written withdrawal thereof. 
 Section 3.8 Effect of Fundamental Change Purchase Notice; Withdrawal. Upon receipt by the Paying Agent of the Fundamental Change Purchase Notice specified in Section 3.7(c), the Holder of the Security
in respect of which such Fundamental Change Purchase Notice was given shall (unless such Fundamental Change Purchase Notice is withdrawn as specified in the following two paragraphs) thereafter be entitled to receive solely the Fundamental Change
Purchase Price with respect to such Security. Such Fundamental Change Purchase Price shall be paid to such Holder, subject to the receipt of funds by the Paying Agent, promptly following the later of (x) the Fundamental Change Purchase Date
with respect to such Security (provided the conditions in Section 3.7(c) have been satisfied) and (y) the time of delivery of such Security to the Paying Agent by the Holder thereof in the manner required by Section 3.7(c). Securities
in respect of which a Fundamental Change Purchase Notice has been given by the Holder thereof may not be converted pursuant to Article IX hereof on or after the date of the delivery of such Fundamental Change Purchase Notice unless such Fundamental
Change Purchase Notice has first been validly withdrawn as specified in the following two paragraphs. 
 A Fundamental Change Purchase Notice
may be withdrawn by means of a written notice of withdrawal delivered to the office of the Paying Agent in accordance with the Fundamental Change Purchase Notice, at any time prior to the close of business on the Fundamental Change Purchase Date,
specifying: 
 (1) the certificate number, if any, of the Security in respect of which such notice of withdrawal is being submitted, or, if
not certificated, the notice must comply with the appropriate depositary procedures, 
  

 25 

 (2) the principal amount of the Security with respect to which such notice of withdrawal is being
submitted, and 
 (3) the principal amount, if any, of such Security which remains subject to the original Fundamental Change Purchase
Notice, and which has been or will be delivered for purchase by the Company. 
 There shall be no purchase of any Securities pursuant to
Section 3.7 if there has occurred (prior to, on or after, as the case may be, the giving, by the Holders of such Securities, of the required Fundamental Change Purchase Notice) and is continuing an Event of Default (other than a default in the
payment of the Fundamental Change Purchase Price with respect to such Securities). The Paying Agent will promptly return to the respective Holders thereof any Securities (x) with respect to which a Fundamental Change Purchase Notice has been
withdrawn in compliance with this Indenture, or (y) held by it during the continuance of an Event of Default (other than a default in the payment of the Fundamental Change Purchase Price with respect to such Securities) in which case, upon such
return, the Fundamental Change Purchase Notice with respect thereto shall be deemed to have been withdrawn. 
 Section 3.9 Deposit of
Fundamental Change Purchase Price. Prior to 10:00 a.m., New York City time, on the Business Day following the Fundamental Change Purchase Date, the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company or a
Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 2.4) an amount of cash (in immediately available funds if deposited on such Business Day) sufficient to pay the
aggregate Fundamental Change Purchase Price of all the Securities or portions thereof which are to be purchased as of the Fundamental Change Purchase Date. 
 Section 3.10 Securities Purchased in Part. Any Certificated Security which is to be purchased only in part shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing) and the Company shall execute and
the Trustee shall authenticate and deliver to the Holder of such Security, without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for,
the portion of the principal amount of the Security so surrendered which is not purchased. 
 Section 3.11 Covenant to Comply With
Securities Laws Upon Purchase of Securities. When complying with the provisions of Section 3.7 (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 

  

 26 

 
or purchase), and subject to any exemptions available under applicable law, the Company shall (i) comply with Rule 13e-4 and Rule 14e-1 (or any
successor provision) under the Exchange Act, (ii) file the related Schedule TO (or any successor schedule, form or report) under the Exchange Act, and (iii) otherwise comply with all Federal and state securities laws so as to permit the
rights and obligations under Section 3.7 to be exercised in the time and in the manner specified in Section 3.7. 
 Section 3.12 Repayment to the Company. The Trustee and the Paying Agent shall return to the Company any cash that remains unclaimed as provided in Section 11 of the Securities, together with interest or dividends, if any,
thereon (subject to the provisions of Section 7.1(f)), held by them for the payment of the Fundamental Change Purchase Price; provided, however, that to the extent that the aggregate amount of cash deposited by the Company pursuant to
Section 3.9 exceeds the aggregate Fundamental Change Purchase Price of the Securities or portions thereof which the Company is obligated to purchase as of the Fundamental Change Purchase Date, then, unless otherwise agreed in writing with the
Company, promptly after the Business Day following the Fundamental Change Purchase Date, the Trustee shall return any such excess to the Company together with interest thereon (subject to the provisions of Section 7.1(f)). 
 ARTICLE IV.

and in the manner provided in the Securities or pursuant to this Indenture. Any amounts of cash to be given to the Trustee or Paying Agent, shall be deposited with the Trustee or Paying Agent by 10:00 a.m., New York City time, by the Company.
Principal amount plus accrued interest, if any, the Redemption Price, the Fundamental Change Purchase Price, the Make-Whole Interest Payment, if any, and cash interest, if any, shall be considered paid on the applicable date due if on such date the

extensions thereof) specified in the SEC’s rules and regulations, copies of its annual report and of 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. The Company also shall comply with the other provisions of TIA Section 314(a). Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not
constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely
conclusively on Officers’ Certificates). 
 Section 4.3 Compliance Certificate. The Company shall deliver to the Trustee
within 120 days after the end of each fiscal year of the Company (beginning with the fiscal year ending on December 31, 2009) an Officers’ Certificate, stating whether or not to the knowledge of the signers thereof, the Company is in
default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and if the Company shall be in default, specifying all
such defaults and the nature and status thereof of which they may have knowledge.

York 10005 (Attention: Corporate Trust Services), shall initially be such office or agency for all of the aforesaid purposes. The Company shall give prompt written notice to the Trustee of the location, and of any change in the location, of any such
office or agency (other than a change in the location of the office of the Trustee). If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 11.2. The Company may also from time to time designate one or more other offices or agencies where the Securities may be
presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or
agency in the Borough of Manhattan, The City of New York, for such purposes. 
 Section 4.6 Delivery of Certain Information. At
any time when the Company is not subject to Section 13 or 15(d) of the Exchange Act, upon the request of a Holder or any beneficial owner of Securities or holder or beneficial owner of shares of Common Stock issued upon conversion thereof, the

 Section 4.7 Treatment of Securities. Each Holder, by acceptance of a Security, and beneficial owner, by acceptance of a beneficial ownership
interest in a Security, agrees to treat the Securities as indebtedness of the Company for U.S. federal income tax purposes and not to take any action inconsistent with such treatment. 
 ARTICLE V. 
 SUCCESSOR CORPORATION 
 Section 5.1 When Company May Merge or Transfer Assets. The Company shall not consolidate with or merge with or into any other Person or
convey, transfer, sell, lease or otherwise dispose of all or substantially all of its properties and assets to any Person, unless: 
 (a)
either (1) the Company shall be the continuing corporation or (2) the Person (if other than the Company) formed by such consolidation or into which the Company is merged or the Person which acquires by conveyance, transfer or lease all or
substantially all of the properties and assets of the Company substantially as an entirety (i) shall be organized and validly existing under the laws of the United States or any State thereof or the District of Columbia and (ii) 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 this Indenture; 
  

 28 

 (b) immediately after giving effect to such transaction, no Default or Event of Default shall have
occurred and be continuing; and 
 (c) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that such consolidation, merger, conveyance, transfer or lease and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, comply with this Article V and that all conditions
precedent herein provided for relating to such transaction have been satisfied. 
 For purposes of the foregoing, the transfer (by lease,
assignment (excluding the grant of a security interest but including any foreclosure thereon), sale or otherwise) of the properties and assets of one or more Subsidiaries (other than to the Company or another Subsidiary), which, if such assets were
owned by the Company, would constitute all or substantially all of the properties and assets of the Company, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company. 
 The successor Person formed by such consolidation or into which the Company is merged or the successor Person 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 this Indenture with the same effect as if such successor had been named as the Company herein; and thereafter, except in the case of a
lease and obligations the Company may have under a supplemental indenture, the Company shall be discharged from all obligations and covenants under this Indenture and the Securities. Subject to Section 8.6, the Company, the Trustee and the
successor Person shall enter into a supplemental indenture to evidence the succession and substitution of such successor Person and such discharge and release of the Company. 
 ARTICLE VI. 
 DEFAULTS AND REMEDIES 
 Section 6.1 Events of Default. So long as any Securities are outstanding, each of the following shall be an “Event of
Default”: 
 (1) the Company defaults in the payment of the principal amount on any Security when the same becomes due and payable
at its Stated Maturity; 
 (2) the Company defaults in its obligation to repurchase any Security, or any portion thereof, upon the exercise
by the Holder of such Holder’s right to require the Company to repurchase such Securities pursuant to and in accordance with Section 3.7 hereof; 
  

 29 

 (3) the Company defaults in its obligation to redeem any Security, or any portion thereof, called for
redemption by the Company pursuant to and in accordance with Section 3.1 hereof; 
 (4) the Company defaults in the payment of any
accrued and unpaid interest or Make-Whole Interest Payment, if any, on any Security, in each case when due and payable, and such default continues for a period of 30 days; 
 (5) the Company fails to comply with any of its covenants or agreements in the Securities or this Indenture (other than those referred to in clauses
(1) through (4) above) and such failure continues for 60 days after receipt by the Company of a Notice of Default; 
 (6) a
default under any indebtedness for money borrowed by the Company or any of its Subsidiaries that is a Significant Subsidiary in an aggregate outstanding principal amount in excess of $10.0 million, for a period of 30 days after written notice of
default is given to the Company by the Trustee or to the Company and the Trustee by Holders of not less than 25% in aggregate principal amount of the Securities then outstanding, which default (A) is caused by the failure to pay principal or
interest when due on such indebtedness by the end of the applicable grace period, if any, unless such indebtedness is discharged, or (B) results in the acceleration of such indebtedness, unless such acceleration is waived, cured, rescinded or
annulled or unless such indebtedness is discharged; 
 (7) the entry by a court having jurisdiction in the premises of (i) a decree or
order for relief in respect of the Company or any of its Subsidiaries that is a Significant Subsidiary, in an involuntary case or proceeding under any applicable bankruptcy, insolvency, reorganization or other similar law or (ii) a decree or
order adjudging the Company or any of its Subsidiaries that is a Significant Subsidiary, as bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the
Company or any of its Subsidiaries that is a Significant Subsidiary, under any applicable law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of
its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 60 consecutive days; or 
 (8) the commencement by the Company or any of its Subsidiaries that is a Significant Subsidiary, of a voluntary case or proceeding under any applicable
bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by the Company or any of its Subsidiaries that is a Significant Subsidiary, to the entry of a
decree or order for relief in respect of the Company or any of its Subsidiaries that is a Significant Subsidiary, in an involuntary case or proceeding under any applicable bankruptcy, insolvency, reorganization or other similar law or to the
commencement of any bankruptcy or insolvency case or proceeding against the Company, or the filing by the Company or any of its Subsidiaries that is a Significant Subsidiary, of a petition or answer or consent seeking reorganization or relief under
any applicable law, or the consent by the Company to the filing of such petition or to the appointment of or the taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of
any substantial part of its property, or the making by the Company or any of its Subsidiaries that is 

  

 30 

 
a Significant Subsidiary, of an assignment for the benefit of creditors, or the admission by the Company or any of its Subsidiaries that is a Significant
Subsidiary, in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company or any of its Subsidiaries that is a Significant Subsidiary, expressly in furtherance of any such action.

 A Default under clause (5) 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 at the time outstanding notify the Company and the Trustee, of the Default and the Company does not cure such Default (and such Default is not waived) within the time specified in clause (5) above
after actual receipt of such notice. Any such notice must specify the Default, require that it be remedied and state that such notice is a “Notice of Default.” 
 The Trustee shall, within 90 days of the occurrence of a Default or Event of Default, give to the Holders of the Securities notice of all uncured
Defaults or Events of Default known to it, its status and what action the Company is taking or proposes to take with respect thereto; provided, however, the Trustee shall be protected in withholding such notice if it, in good faith, determines that
the withholding of such notice is in the best interest of such Holders, except in the case of a Default or Event of Default under clause (1), (2), (3) or (4) above. 
 Section 6.2 Acceleration. If an Event of Default (other than an Event of Default specified in Section 6.1(7) or (8) with respect to
the Company) occurs and is continuing (the Event of Default not having been cured or waived as provided in this Article VI), the Trustee by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities at the
time outstanding by notice to the Company and the Trustee, may declare the principal amount plus accrued and unpaid interest plus Make-Whole Interest Payment, if any, on all the Securities to be immediately due and payable. Upon such a declaration,
such accelerated amount shall be due and payable immediately. If an Event of Default specified in Section 6.1(7) or (8) occurs (with respect to the Company) and is continuing, the principal amount plus accrued and unpaid interest plus
Make-Whole Interest Payment, if any, on all the Securities shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Securityholders. The Holders of a majority in aggregate principal
amount of the Securities at the time outstanding, by notice to the Trustee (and without notice to any other Securityholder) may rescind or annul an acceleration and its consequences if the rescission or annulment would not conflict with any judgment
or decree and if all existing Events of Default have been cured or waived except nonpayment of the principal amount plus accrued and unpaid interest plus Make-Whole Interest Payment, if any, that have become due solely as a result of acceleration
and if all amounts due to the Trustee under Section 7.7 have been paid. No such rescission or annulment shall affect any subsequent Default or impair any right consequent thereto. 
 Section 6.3 Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the
payment of the principal amount plus accrued and unpaid interest plus Make-Whole Interest Payment, if any, on the Securities or to enforce the performance of any provision of the Securities or this Indenture. 
 The Trustee may maintain a proceeding even if the Trustee does not possess any of the Securities or does not produce any of the Securities 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. 
  

 31 

 Section 6.4 Waiver of Past Defaults. The Holders of a majority in aggregate principal amount
of the Securities at the time outstanding, by notice to the Trustee (and without notice to any other Securityholder), may waive an existing Default or Event of Default and its consequences except (i) an Event of Default described in
Section 6.1(1), 6.1(2), 6.1(3) or 6.1(4), (ii) a Default or Event of Default in respect of a provision that under Section 8.2 cannot be amended without the consent of each Securityholder affected or (iii) a Default or Event of
Default which constitutes a failure to convert any Security in accordance with the terms of Article IX. 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 Event of
Default or impair any consequent right. This Section 6.4 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 this Indenture, as permitted by the TIA. 
 Section 6.5 Control by Majority. The Holders of a majority in aggregate principal amount of the Securities at the time outstanding may direct
the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this
Indenture or that the Trustee determines in good faith is unduly prejudicial to the rights of other Securityholders or would involve the Trustee in personal liability unless the Trustee is offered indemnity satisfactory to it. This Section 6.5
shall be in lieu of Section 316(a)(1)(A) of the TIA and such Section 316(a)(1)(A) is hereby expressly excluded from this Indenture, as permitted by the TIA. 
 Section 6.6 Limitation on Suits. A Securityholder may not pursue any remedy with respect to this Indenture or the Securities unless: 
 (1) the Holder gives to the Trustee written notice stating that an Event of Default is continuing; 
 (2) the Holders of at least 25% in aggregate principal amount of the Securities at the time outstanding make a written request to the Trustee to pursue
the remedy; 
 (3) such Holder or Holders offer to the Trustee security or indemnity satisfactory to the Trustee against any loss, liability
or expense; 
 (4) the Trustee does not comply with the request within 60 days after receipt of such notice, request and offer of security
or indemnity; and 
 (5) the Holders of a majority in aggregate principal amount of the Securities at the time outstanding do not give the
Trustee a direction inconsistent with the request during such 60-day period. 
 A Securityholder may not use this Indenture to prejudice the
rights of any other Securityholder or to obtain a preference or priority over any other Securityholder. 
 Section 6.7 Rights of
Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of the principal amount, Redemption Price, Fundamental Change Purchase Price or interest in respect of the Securities
held by such Holder, on or after the respective due dates expressed in the Securities or any Redemption 

  

 32 

 
Date, and to convert the Securities in accordance with Article IX, or to bring suit for the enforcement of any such payment on or after such respective dates
or the right to convert, shall not be impaired or affected adversely without the consent of such Holder. 
 Section 6.8 Collection
Suit by Trustee. If an Event of Default described in Section 6.1(1), (2), (3) or (4) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole
amount owing with respect to the Securities and the amounts provided for in Section 7.7. 
 Section 6.9 Trustee May File Proofs
of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the
property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal amount, Redemption Price, Fundamental Change Purchase Price, Make-Whole Interest Payment, if any, or interest in respect of the
Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of any such amount) shall be entitled and empowered, by
intervention in such proceeding or otherwise, 
 (a) to file and prove a claim for the whole amount of the principal amount, Redemption
Price, Fundamental Change Purchase Price, Make-Whole Interest Payment, if any, or interest and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel or any other amounts due the Trustee under Section 7.7) and of the Holders allowed in such judicial proceeding, and 
 (b) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.7.

 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 Section 6.10 Priorities. If the Trustee collects any money pursuant to this Article VI, it shall pay out the money in the following order:

 FIRST: to the Trustee for amounts due under Section 7.7; 
 SECOND: to Securityholders for amounts due and unpaid on the Securities for the principal amount, Redemption Price, Fundamental Change Purchase Price,
Make-Whole Interest Payment, if any, or interest as the case may be, ratably, without preference or priority of any kind, according to such amounts due and payable on the Securities; and 
  

 33 

 THIRD: the balance, if any, to the Company. 
 The Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this Section 6.10. At least 15 days before such
record date, the Trustee shall mail to each Securityholder and the Company a notice that states the record date, the payment date and the amount to be paid. 
 Section 6.11 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in
its discretion may require the filing by any party litigant (other than the Trustee) in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees
and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to
Section 6.7 or a suit by Holders of more than 10% in aggregate principal amount of the Securities at the time outstanding. This Section 6.11 shall be in lieu of Section 315(e) of the TIA and such Section 315(e) is hereby
expressly excluded from this Indenture, as permitted by the TIA. 
 Section 6.12 Waiver of Stay, Extension or Usury Laws. The Company
covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury or other law wherever enacted, now
or at any time hereafter in force, which would prohibit or forgive the Company from paying all or any portion of the principal amount, Redemption Price, Make-Whole Interest Payment, if any, or Fundamental Change Purchase Price in respect of
Securities, or any interest on such amounts, as contemplated herein, or which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage
of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 
 ARTICLE VII. 
 TRUSTEE

 Section 7.1 Duties of Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a prudent person

 (b) Except during the continuance of an
Event of Default: 
 (1) the Trustee need perform only those duties that are specifically set forth in this Indenture and no others; and

Indenture, but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the
Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture, but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein. This

that: 
 (1) this Section (c) does not limit the effect of Section (b) of this Section 7.1;

negligent in ascertaining the pertinent facts; and 
 (3) the Trustee shall not be liable with respect to any action it takes or omits to
take in good faith in accordance with a direction received by it pursuant to Section 6.5. Subparagraphs(c)(1), (2) and (3) shall be in lieu of Sections 315(d)(1), 315(d)(2) and 315(d)(3) of the TIA and such Sections 315(d)(1),

 (a) the
Trustee may conclusively rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of
indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties; 
 (b) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein
specifically prescribed) may, in the absence of bad faith on its part, conclusively rely upon an Officers Certificate; 
  

 35 

 (c) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either
directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder; 
 (d) the Trustee shall not be liable for any action taken, suffered, or omitted to be taken by it in good faith which it believes to be authorized or
within its rights or powers conferred under this Indenture;

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

 (g) any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order and any
resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution; 
 (h) the Trustee shall not be bound to make any
investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but
the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Company, personally or by agent or attorney at the sole cost of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation; 
 (i) the Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge
thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities and this Indenture; 
 (j) the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are
extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent, custodian and other Person employed to act hereunder; 
 (k) in no event shall the Trustee be responsible or liable for special, indirect or consequential loss of damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the

 36 

 (l) the Trustee may request that the Company deliver an Officers’ Certificate setting forth the
names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may be signed by any Person authorized to sign an Officers’ Certificate, including any
Person specified as so authorized in any such certificate previously delivered and not superseded. 
 Section 7.3 Individual Rights of
Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent,
Registrar, Conversion Agent or co-registrar may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11. 
 Section 7.4 Trustee’s Disclaimer. The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use or application of the proceeds from
the Securities, it shall not be responsible for any statement in the registration statement for the Securities under the Securities Act or in any offering document for the Securities, the Indenture or the Securities (other than its certificate of
authentication), or the determination as to which beneficial owners are entitled to receive any notices hereunder. 
 Section 7.5 Notice
of Defaults. If a Default occurs and if it is known to the Trustee, the Trustee shall give to each Securityholder notice of the Default within 90 days after it occurs or, if later, within 15 days after it is known to the Trustee, unless such
Default shall have been cured or waived before the giving of such notice. Notwithstanding the preceding sentence, except in the case of a Default described in Section 6.1(1), (2), (3) or (4), the Trustee may withhold the notice if and so
long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interest of the Securityholders. The preceding sentence shall be in lieu of the proviso to Section 315(b) of the TIA and such proviso
is hereby expressly excluded from this Indenture, as permitted by the TIA. The Trustee shall not be deemed to have knowledge of a Default unless a Responsible Officer of the Trustee has received written notice of such Default, which notice
specifically references this Indenture and the Securities. 
 Section 7.6 Reports by Trustee to Holders. Within 60 days after each
May 15 beginning with the May 15 following the date of this Indenture, the Trustee shall mail to each Securityholder a brief report dated as of such May 15 that complies with TIA Section 313(a), if required by such
Section 313(a). The Trustee also shall comply with TIA Section 313(b). 
 A copy of each report at the time of its mailing to
Securityholders shall be filed with the SEC and each securities exchange, if any, on which the Securities are listed. The Company agrees to notify the Trustee promptly whenever the Securities become listed on any securities exchange and of any
delisting thereof. 
 Section 7.7 Compensation and Indemnity. The Company agrees: 
 (a) to pay to the Trustee from time to time such compensation as the Company and the Trustee shall from time to time agree in writing for all services
rendered by it hereunder (which compensation shall not be limited (to the extent permitted by law) by any provision of law in regard to the compensation of a trustee of an express trust); 
  

 37 

 (b) to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances
incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses, advances and disbursements of its agents and counsel), except any such expense, disbursement or advance as
may be attributable to its negligence or bad faith; and 
 (c) to indemnify the Trustee or any predecessor Trustee and their agents for, and
to hold them harmless against, any loss, damage, claim, liability, cost or expense (including attorney’s fees and expenses, and taxes (other than taxes based upon, measured by or determined by the income of the Trustee and any and all franchise
taxes of the Trustee)) incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of this trust, including the costs and expenses of defending itself against any claim (whether
asserted by the Company or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder. 
 To secure the Company’s payment obligations in this Section 7.7, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to
pay the principal amount, Redemption Price, Fundamental Change Purchase Price, Make-Whole Interest Payment, if any, or interest as the case may be, on particular Securities. 
 The Company’s payment obligations pursuant to this Section 7.7 shall survive the discharge of this Indenture and the resignation or removal of
the Trustee. When the Trustee incurs expenses or renders services after the occurrence of a Default specified in Section 6.1(6) or (7), 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 bankruptcy law. 
 Section 7.8 Replacement of Trustee. The
Trustee may resign by so notifying the Company; provided, however, no such resignation shall be effective until a successor Trustee has accepted its appointment pursuant to this Section 7.8. The Holders of a majority in aggregate principal
amount of the Securities at the time outstanding may remove the Trustee by so notifying the Trustee and the Company. The Company shall remove the Trustee if: 
 (1) the Trustee fails to comply with Section 7.10; 
 (2) the Trustee is adjudged bankrupt or
insolvent; 
 (3) a receiver or public officer takes charge of the Trustee or its property; or 
 (4) the Trustee otherwise becomes incapable of acting. 
 If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint, by resolution of its Board of Directors, a successor Trustee. 
 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company satisfactory in form and substance
to the retiring Trustee and the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, 

  

 38 

 
and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its
succession to Securityholders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.7. 
 If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holders of a majority in aggregate principal amount of the Securities at the time outstanding may petition any court of competent jurisdiction at the expense of the Company for the appointment of a successor Trustee. 
 If the Trustee fails to comply with Section 7.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee. 
 Section 7.9 Successor Trustee by Merger. If the Trustee consolidates with, merges or
converts into, or transfers all or substantially all its corporate trust business or assets (including the administration of the trust created by this Indenture) to, another corporation, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee. 
 Section 7.10 Eligibility; Disqualification. The Trustee shall at all times satisfy the
requirements of TIA Sections 310(a)(1) and 310(b). The Trustee (or its parent holding company) shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. Nothing herein
contained shall prevent the Trustee from filing with the SEC the application referred to in the penultimate paragraph of TIA Section 310(b). 
 Section 7.11 Preferential Collection of Claims Against Company. The Trustee shall comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed
shall be subject to TIA Section 311(a) to the extent indicated therein. 
 Section 7.12 Force Majeure. In no event shall the
Trustee be responsible or liable for any failure or delay in the performance of its obligations under this Indenture arising out of or caused by, directly or indirectly, forces beyond its reasonable control, including without limitation strikes,
work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of god, and interruptions, loss or malfunctions or utilities, communications or computer (software or hardware) services.

Securities in any material respect; and 
 (h) add or modify any other provisions herein with respect to matters or questions arising
hereunder which the Company and the Trustee may deem necessary or desirable and that will not, in the good faith opinion of the Board of Directors of the Company (as evidenced by a Board Resolution), adversely affect the interests of the Holders of
Securities. 
 Section 8.2 With Consent of Holders. Except as provided below in this Section 8.2 and in Section 8.1, this
Indenture or the Securities may be amended, modified or supplemented, and noncompliance in any particular instance with any provision of this Indenture or the Securities may be waived, in each case with the written consent of the Holders of at least
a majority of the principal amount of the Securities at the time outstanding. 
 Without the written consent or the affirmative vote of each

 (a) change the maturity of the principal
or the date any installment of interest or Make-Whole Interest Payment, if any, is due on, any Security;

 (i) increase the Conversion Price (except as otherwise expressly permitted by the terms of this
Indenture). 
 It shall not be necessary for the consent of the Holders under this Section 8.2 to approve the particular form of any
proposed amendment, but it shall be sufficient if such consent approves the substance thereof. 
 After an amendment under this
Section 8.2 becomes effective, the Company shall mail to each Holder a notice briefly describing the amendment. 
 Nothing in this
Section 8.2 shall impair the ability of the Company and the Trustee to amend this Indenture or the Securities without the consent of any Securityholder to provide for the assumption of the Company’s obligations to the Holders of Securities
in the case of a merger, consolidation, conveyance, transfer or lease pursuant to Article V hereof. 
 Section 8.3 Compliance with Trust
Indenture Act. Every supplemental indenture executed pursuant to this Article shall comply with the TIA. 
 Section 8.4 Revocation and
Effect of Consents, Waivers and Actions. Until an amendment, waiver or other action by Holders becomes effective, a consent thereto by a Holder of a Security hereunder is a continuing consent by the Holder and every subsequent Holder of that
Security or portion of the Security that evidences the same obligation as the consenting Holder’s Security, even if notation of the consent, waiver or action is not made on the Security. However, any such Holder or subsequent Holder may revoke
the consent, waiver or action as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date the amendment, waiver or action becomes effective. After an amendment, waiver or action
becomes effective, it shall bind every Securityholder. 
 Section 8.5 Notation on or Exchange of Securities. Securities authenticated
and delivered after the execution of any supplemental indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the

Trustee in exchange for outstanding Securities. 
  

 41 

 Section 8.6 Trustee to Sign Supplemental Indentures. The Trustee shall sign any supplemental
indenture authorized pursuant to this Article VIII if the amendment contained therein does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign such supplemental
indenture. In signing such supplemental indenture the Trustee shall receive, and (subject to the provisions of Section 7.1) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such
amendment is authorized or permitted by this Indenture. 
 Section 8.7 Effect of Supplemental Indentures. Upon the execution of any
supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter
authenticated and delivered hereunder shall be bound thereby. 
 ARTICLE IX. 
 CONVERSIONS 
 Section 9.1 Conversion Privilege. 
 (a) Subject to and upon compliance with the provisions of this Article IX, a Holder of a Security shall have the right, at such Holder’s option, to
convert all or any portion of the principal amount of such Security (if the portion of such principal amount to be converted is $1,000 or an integral multiple of $1,000) of such Security into the number of shares of Common Stock obtained by dividing
the principal amount so converted by the Conversion Price in effect on the date of conversion, at any time prior to the close of business on the Business Day prior to the Stated Maturity of the Securities. Notwithstanding the foregoing, (i) in no
event will any Holder be entitled to receive Common Stock upon conversion to the extent (but only to the extent) that such receipt would cause such converting Holder to become, directly or indirectly, a Beneficial Owner of more than 19.9% of the
shares of Common Stock outstanding at such time; (ii) any purported delivery of shares of Common Stock upon conversion of the Securities shall be void and have no effect to the extent (but only to the extent) that such delivery would result in the
converting Holder becoming the Beneficial Owner of more than 19.9% of the shares of Common Stock outstanding at such time; and (iii) if any delivery of shares of Common Stock owed to a Holder upon conversion of the Securities is not made, in whole
or in part, as a result of this limitation, the Company’s obligation to make such delivery shall not be extinguished and the Company shall deliver such shares as promptly as practicable after any such converting Holder gives notice to the
Company that such delivery would not result in such Holder being the Beneficial Owner of more than 19.9% of the shares of Common Stock outstanding at such time; provided, however, the limitations set forth in the foregoing clauses (i) through (iii)
shall not apply if such conversion would not result in a change of control requiring the consent of holders of the Common Stock pursuant to the rules of The Nasdaq Stock Market or any national or regional securities exchange or other market on which
the Common Stock is then traded or quoted and such consent has not been obtained. 
 (b) Subject to Section 9.4 and Section 9.12,
if a Holder elects to convert a Security in connection with clauses (i) or (iii) under a Fundamental Change referred to in Section 3.7 (or in connection with a transaction that would have been a Fundamental Change under such clause
(i) or (iii) but for the existence of the 110% Trading Price Exception (as defined in Section 3.7)) pursuant to which 10% or more of the consideration for the Common Stock (other than cash payments for fractional shares and cash
payments made in respect of dissenters’ appraisal rights) in such transaction consists of cash or securities (or other property) that are not traded or scheduled to be traded immediately following such transaction on a U.S. national securities
exchange (a “Non-Stock Change of Control”), the Company will increase the number of shares of Common Stock issuable upon conversion of the Security by a number of additional shares of Common Stock (the “Additional Common
Stock”) as set forth below. The number of shares of Additional Common Stock will be determined by reference to the table below, based on the date on which the Non-Stock Change of Control becomes effective (the “Effective
Date”) and the price (the “Stock Price”) paid per share for the Common Stock in the Non-Stock Change of Control. If Holders of Common Stock receive only cash in the Non-Stock Change of Control, the Stock Price shall be the
cash amount paid per share. Otherwise, the Stock Price shall be the average of the Sale Prices of the Common Stock on the five Trading Days prior to but not including the Effective Date of such Non-Stock Change of Control. 
 The Stock Prices and number of shares of Additional Common Stock set forth in the table below will be adjusted as of any date on which the Conversion
Price is adjusted. On such date, the Stock Prices shall be adjusted by multiplying: 
 (1) the Stock Prices applicable immediately prior to
such adjustment, by 
  

 42 

 (2) a fraction, of which 
 (A) the numerator shall be the Conversion Price as so adjusted, and 
 (B) the denominator shall be the Conversion Price immediately prior to the adjustment giving rise to the Stock Price adjustment.

 The number of shares of Additional Common Stock shall be correspondingly adjusted in the same manner as the adjustments described in
Section 9.3. The following table sets forth the Stock Price and number of shares of Additional Common Stock issuable per $1,000 aggregate principal amount of Securities: 
  

																									
	 STOCK PRICE

 If the Stock Price and Effective Date are not set forth on the table above and the Stock Price is: 
 (A) between two Stock Prices on the table or the Effective Date is between two dates on the table, the number of shares of Additional
Common Stock will be determined by straight-line interpolation between the number of shares of Additional Common Stock set forth for the higher and lower Stock Price and the two Effective Dates, as applicable, based on a 360-day year; 
 (B) in excess of $1.76 per share (subject to adjustment), no shares of Additional Common Stock will be issued upon conversion; or

 (C) less than $0.59 per share (subject to adjustment), no shares of Additional Common Stock will be issued upon
conversion. 
 Notwithstanding the foregoing, in no event shall the total number of shares of Common Stock issuable upon conversion exceed
1,707.78 per $1,000 of aggregate principal amount of Securities, subject to adjustments in the same manner as the Conversion Price in Section 9.3. 
 (c) The Company shall provide notice to all Holders and to the Trustee at least 15 Trading Days prior to the anticipated Effective Date of a Non-Stock Change of Control. The Company must also provide notice to all
Holders and to the Trustee upon the effectiveness of such Non-Stock Change of Control. 
  

 43 

 (d) Subject to Sections 9.4 and 9.12, if a Holder elects to convert a Security in connection with a
Non-Stock Change of Control, the Company will pay to the Holders of the Securities so converted cash with respect to the Security so converted in an amount determined in accordance with the following table per $1,000 principal amount of the
Securities so converted (the “Make-Whole Interest Payment”): 
  

				
	 Effective Date

	  	$	13.83
	 May 1, 2012
	  	$	5.24
	 May 1, 2013
	  	 	0

 If the date of conversion in connection with a Non-Stock Change of Control does not occur on one
of the Effective Dates set forth on the table above, the amount of the Make-Whole Interest Payment shall be determined by straight line interpolation between the two Effective Dates on which such conversion occurs. No Make-Whole Interest Payment
shall be payable for such a conversion in connection with a Non-Stock Change of Control with an Effective Date that is after May 1, 2012. 
 (e) Subject to Section 9.12, Holders may surrender Securities for conversion and receive the Additional Common Stock pursuant to Section 9.1(b) and Make-Whole Interest Payment pursuant to Section 9.1(d) at any time from and after the date
which is 15 days prior to the anticipated Effective Date of such Fundamental Change until and including the date which is 15 days after the actual Effective Date (or, if such transaction also results in Holders having a right to require the Company
to repurchase their Securities, until the Fundamental Change Purchase Date with respect to such Fundamental Change). 
 Section 9.2
Conversion Procedure; Conversion Price; Fractional Shares. 
 (a) Each Security shall be convertible at the office of the Conversion Agent
into fully paid and nonassessable shares (calculated to the nearest 1/100th of a share) of Common Stock. The Security will be converted into shares of Common Stock at the Conversion Price therefor. No payment or adjustment shall be made in respect
of dividends on the Common Stock or accrued interest on a converted Security, except as described in Section 9.9 hereof. The Company shall not issue any fraction of a share of Common Stock in connection with any conversion of Securities, but
instead shall, subject to Section 9.3(k) hereof, make a cash payment (calculated to the nearest cent) equal to such fraction multiplied by the Sale Price of the Common Stock on the last Trading Day prior to the date of conversion.
Notwithstanding the foregoing, a Security in respect of which a Holder has delivered a Fundamental Change Purchase Notice exercising such Holder’s option to require the Company to repurchase such Security may be converted only if such notice of
exercise is withdrawn in accordance with Section 3.8 hereof. 
 (b) Before any Holder of a Security shall be entitled to convert the
same into Common Stock, such Holder shall, in the case of Global Securities, comply with the procedures of the Depositary in effect at that time, and in the case of Certificated Securities, surrender such Securities, duly endorsed to the Company or
in blank, at the office of the Conversion Agent, and shall give written notice to the Company at said office or place that such Holder elects to convert the same and shall state in writing therein the principal amount of Securities to be converted
and the name or names (with addresses) in which such Holder wishes the certificate or certificates for Common Stock to be issued. 
 Before
any such conversion, a Holder also shall pay all funds required, if any, relating to interest on the Securities, as provided in Section 9.9, and all taxes or duties, if any, as provided in Section 9.8. 
 If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares of Common Stock which shall be
deliverable upon conversion shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted thereby) so surrendered. Subject to the next succeeding sentence, the Company will,
as soon as practicable thereafter, issue and deliver at said office or place to such Holder of a Security, or to such Holder’s nominee or nominees, certificates for the number of full shares of Common Stock to which such Holder shall be
entitled as aforesaid, together with cash in lieu of any fraction of a share to which such Holder would otherwise be entitled. The Company shall not be required to deliver certificates for shares of Common Stock while the stock transfer books for
such stock or the security register are duly closed for any purpose, but certificates for shares of Common Stock shall be issued and delivered as soon as practicable after the opening of such books or security register. 
  

 44 

 (c) A Security shall be deemed to have been converted as of the close of business on the date of the
surrender of such Securities for conversion and compliance with the other requirements of this Section 9.2 as provided above, and the Person or Persons entitled to receive the Common Stock issuable upon such conversion shall be treated for all
purposes as the record Holder or Holders of such Common Stock as of the close of business on such date. 
 (d) In case any Security shall be
surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Security so surrendered, without charge to such Holder (subject to the provisions of
Section 9.8 hereof), a new Security or Securities in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Securities. 
 Section 9.3 Adjustment of Conversion Price. The Conversion Price shall be adjusted from time to time as follows: 
 (a) In case the Company shall, at any time or from time to time while any of the Securities are outstanding, pay a dividend or make a distribution in
shares of Common Stock to all holders of its outstanding shares of Common Stock, then the Conversion Price in effect at the opening of business on the date following the record date fixed for the determination of stockholders entitled to receive
such dividend or other distribution shall be reduced by multiplying such Conversion Price by a fraction: 
 (1) the numerator of which shall
be the number of shares of Common Stock outstanding at the close of business on the Record Date fixed for such determination; and 
 (2) the
denominator of which shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution. 
 Such reduction shall become effective immediately after the opening of business on the day following the Record Date fixed for such determination. If any dividend or distribution of the type described in this Section 9.3(a) is declared
but not so paid or made, the Conversion Price shall again be adjusted to the Conversion Price which would then be in effect if such dividend or distribution had not been declared. 
 (b) In case the Company shall, at any time or from time to time while any of the Securities are outstanding, subdivide its outstanding shares of Common
Stock into a greater number of shares of Common Stock, then the Conversion Price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately reduced, and conversely, in
case the Company shall, at any time or from time to time while any of the Securities are outstanding, combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock, then the Conversion Price in effect at the opening
of business on the day following the day upon which such combination becomes effective shall be proportionately increased. 
 Such reduction
or increase, as the case may be, shall become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective. 
  

 45 

 (c) In case the Company shall, at any time or from time to time while any of the Securities are
outstanding, issue rights or warrants (other than any rights or warrants referred to in Section 9.3(d)) to all or substantially all holders of its shares of Common Stock entitling them to subscribe for or purchase, for a period of up to 45
days, shares of Common Stock (or securities convertible into shares of Common Stock) at a price per share (or having a conversion price per share) less than the Sale Price on the Business Day immediately preceding the date of the announcement of
such issuance (treating the conversion price per share of the securities convertible into Common Stock as equal to (x) the sum of (i) the price for a unit of the security convertible into Common Stock and (ii) any additional
consideration initially payable upon the conversion of such security into Common Stock divided by (y) the number of shares of Common Stock initially underlying such convertible security), then the Conversion Price shall be adjusted so that the
same shall equal the price determined by multiplying the Conversion Price in effect at the opening of business on the date after such date of announcement by a fraction: 
 (1) the numerator of which shall be the number of shares of Common Stock outstanding on the close of business on the date of announcement, plus the number of shares or securities which the aggregate offering price of
the total number of shares or securities so offered for subscription or purchase (or the aggregate conversion price of the convertible securities so offered) would purchase at such Sale Price of the Common Stock; and 
 (2) the denominator of which shall be the number of shares of Common Stock outstanding at the close of business on the date of announcement, plus the
total number of additional shares of Common Stock so offered for subscription or purchase (or into which the convertible securities so offered are convertible). 
 Such adjustment shall become effective immediately after the opening of business on the day following the date of announcement of such issuance. To the extent that shares of Common Stock (or securities convertible
into 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 Price shall be readjusted to the Conversion Price which would then be in effect had the
adjustments made upon the issuance of such rights or warrants been made on the basis of the delivery of only the number of shares of Common Stock (or securities convertible into shares of Common Stock) actually delivered. In the event that such
rights or warrants are not so issued, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if the date fixed for the determination of stockholders entitled to receive such rights or warrants had not
been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Sale Price, and in determining the aggregate offering price of such shares of Common Stock, there
shall be taken into account any consideration received for such rights or warrants, the value of such consideration if other than cash, to be determined by the Board of Directors. 
 (d) In case the Company shall, at any time or from time to time while any of the Securities are outstanding, by dividend or otherwise, distribute to all
or substantially all holders of its shares of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation and the Common Stock is not changed or exchanged),
shares of Capital Stock (other than any dividends or distributions to which Section 9.3(a) applies and distributions of Common Stock to which Section 9.3(a) 

  

 46 

 
applies), evidences of its indebtedness or other assets, including securities, but excluding (i) any rights or warrants referred to in
Section 9.3(c) and (ii) dividends or distributions of stock, securities or other property or assets (including cash) in connection with a reclassification, consolidation, merger, statutory share exchange, combination, sale or conveyance to
which Section 9.4 applies (such capital stock, evidence of its indebtedness, and other assets or securities being distributed hereinafter in this Section 9.3(d) called the “distributed assets”), then, in each such case,
subject to the second and third succeeding paragraphs and the last paragraph of this Section 9.3(d), the Conversion Price shall be reduced so that the same shall be equal to the price determined by multiplying the Conversion Price in effect
immediately prior to the close of business on the Record Date with respect to such distribution by a fraction: 
 (1) the numerator of which
shall be the Current Market Price of the Common Stock, less the Fair Market Value on such date of the portion of the distributed assets so distributed applicable to one share of Common Stock (determined on the basis of the number of shares of Common
Stock outstanding on the record date)(determined as provided in Section 9.3(g)); and 
 (2) the denominator of which shall be such
Current Market Price. 
 Such reduction shall become effective immediately prior to the opening of business on the day following the Record
Date for such distribution. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been
declared. 
 If the Board of Directors determines the Fair Market Value of any distribution for purposes of this Section 9.3(d) by
reference to the actual or when issued trading market for any distributed assets comprising all or part of such distribution, it must in doing so consider the prices in such market over the same period (the “Reference Period”) used
in computing the Current Market Price pursuant to Section 9.3(g) to the extent possible, unless the Board of Directors determines in good faith that determining the Fair Market Value during the Reference Period would not be in the best interest
of the Holders. Notwithstanding the foregoing, in the event any such distribution consists of shares of capital stock of, or similar equity interests in, one or more of the Company’s Subsidiaries (a “Spin-Off”), the Conversion
Price shall be reduced so that the same shall be equal to the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on the Record Date with respect to such distribution by a fraction: 

(1) the numerator of which shall be the Current Market Price on such date; and 
 (2) the denominator of which shall be the Current Market Price of the Common Stock, plus the Fair Market Value on such date of the portion of the
distributed assets so distributed applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding on the record date) (determined as set forth in the third and fourth succeeding sentences).

 Such reduction shall become effective immediately prior to the opening of business on the day following the last Trading Day of the
Spin-Off Valuation Period (as defined below). In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be 

  

 47 

 
adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared. In the case of a Spin-Off, the Fair
Market Value of the securities to be distributed shall equal the average of the closing sale prices of such securities on the principal securities market on which such securities are traded for the five consecutive Trading Days commencing on and
including the sixth day of trading of those securities after the effectiveness of the Spin-Off (the “Spin-Off Valuation Period”), and the Current Market Price shall be measured for the same period. In the event, however, that an
underwritten initial public offering of the securities in the Spin-Off occurs simultaneously with the Spin-Off, Fair Market Value of the securities distributed in the Spin-Off shall mean the initial public offering price of such securities and the
Current Market Price shall mean the Sale Price for the Common Stock on the same Trading Day. 
 Rights or warrants distributed by the Company
to all holders of its shares of Common Stock entitling them to subscribe for or purchase shares of the Company’s capital stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified
event or events (“Trigger Event”), (i) are deemed to be transferred with such shares of Common Stock, (ii) are not exercisable and (iii) are also issued in respect of future issuances of shares of Common Stock shall
be deemed not to have been distributed for purposes of this Section 9.3(d) (and no adjustment to the Conversion Price under this Section 9.3(d) will be required) until the occurrence of the earliest Trigger Event. If such right or warrant
is subject to subsequent events, upon the occurrence of which such right or warrant shall become exercisable to purchase different distributed assets, evidences of indebtedness or other assets, or entitle the holder to purchase a different number or
amount of the foregoing or to purchase any of the foregoing at a different purchase price, then the occurrence of each such event shall be deemed to be the date of issuance and record date with respect to a new right or warrant (and a termination or
expiration of the existing right or warrant without exercise by the holder thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the
preceding sentence) with respect thereto, that resulted in an adjustment to the Conversion Price under this Section 9.3(d)): 
 (1) in
the case of any such rights or warrants which shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Price shall be readjusted upon such final redemption or repurchase to give effect to such distribution
or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder of shares of Common Stock with respect to such rights or warrants (assuming such holder had
retained such rights or warrants), made to all holders of shares of Common Stock as of the date of such redemption or repurchase; and 
 (2)
in the case of such rights or warrants which shall have expired or been terminated without exercise, the Conversion Price shall be readjusted as if such rights and warrants had never been issued. 
 For purposes of this Section 9.3(d) and Section 9.3(a), 9.3(b) and 9.3(c), any dividend or distribution to which this Section 9.3(d) is
applicable that also includes (i) shares of Common Stock, (ii) a subdivision or combination of shares of Common Stock to which Section 9.3(b) applies or (iii) rights or warrants to subscribe for or purchase shares of Common Stock
to which Section 9.3(c) applies (or any combination thereof), shall be deemed instead to be: 
 (1) a dividend or distribution of the
evidences of indebtedness, assets, shares of capital stock, rights or warrants, other than such shares of Common Stock, such subdivision or combination or such rights or warrants to which Section 9.3(a), 9.3(b) and 9.3(c) apply, respectively
(and any Conversion Price reduction required by this Section 9.3(d) with respect to such dividend or distribution shall then be made), immediately followed by 
  

 48 

 (2) a dividend or distribution of such shares of Common Stock, such subdivision or combination or such
rights or warrants (and any further Conversion Price reduction required by Sections 9.3(a), 9.3(b), and 9.3(d) with respect to such dividend or distribution shall then be made), except: 
 (A) the Record Date of such dividend or distribution shall be substituted as (i)”the date fixed for the determination of stockholders entitled to
receive such dividend or other distribution,” “Record Date fixed for such determinations” and “Record Date” within the meaning of Section 9.3(a) and 9.3(b), (ii) “the day upon which such subdivision becomes
effective” and “the day upon which such combination becomes effective” within the meaning of Section 9.3(b), and (iii) as “the date fixed for the determination of stockholders entitled to receive such rights or
warrants,” “the Record Date fixed for the determination of the stockholders entitled to receive such rights or warrants” and such “Record Date” within the meaning of Section 9.3(c); and 
 (B) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding at the close of business on the date
fixed for such determination” within the meaning of Section 9.3(a) and any reduction or increase in the number of shares of Common Stock resulting from such subdivision or combination shall be disregarded in connection with such dividend
or distribution. 
 In the event of any distribution referred to in this Section 9.3(d) in which (i) the value of such distribution
per share of Common Stock equals or exceeds the average of the Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on the Record Date for such distribution, or (ii) such average of the Sale Prices of the Common
Stock exceeds the Fair Market Value of such distribution applicable to one share of Common Stock (as determined by the Board of Directors) by less than $1.00, then, in each such case, in lieu of an adjustment to the Conversion Price, adequate
provision shall be made so that each Holder shall have the right to receive upon conversion of a Security, in addition to shares of Common Stock, the kind and amount of such distribution such Holder would have received had such Holder converted such
Security immediately prior to the Record Date for determining the shareholders entitled to receive the distribution. 
 No adjustment to the
Conversion Price or the ability of a Holder of a Security to convert will be made if the Holder may otherwise participate in such distribution without conversion. 
 (e) In case the Company shall, by dividend or otherwise, distribute to all or substantially all holders of its Common Stock cash (excluding any dividend or distribution in connection with the liquidation, dissolution
or winding up of the Company, whether voluntary or involuntary), then, in such case, the Conversion Price shall be reduced so that the same shall equal the rate determined by dividing the Conversion Price in effect on the applicable record date by a
fraction, 
  

 49 

 (1) the numerator of which shall be the Current Market Price on such record date; and 
 (2) the denominator of which shall be the Current Market Price minus the amount distributed per ordinary share of Common Stock. 
 Such adjustment shall become effective immediately after the opening of business on the day following the Record Date fixed for the determination of the
stockholders entitled to receive such cash dividend or other distribution consisting exclusively of cash. If any dividend or distribution of the type described in this Section 9.3(e) is declared but not so paid or made, the Conversion Price
shall again be adjusted to the Conversion Price which would then be in effect if such dividend or distribution had not been declared. 
 (f)
In case a tender or exchange offer made by the Company or any Subsidiary for all or any portion of the Common Stock shall expire and such tender or exchange offer (as amended upon the expiration thereof) shall require the payment to stockholders of
consideration per share of Common Stock having a Fair Market Value (as determined by the Board of Directors, whose determination shall be conclusive and described in a resolution of the Board of Directors) that as of the last time (the
“Expiration Time”) tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended) exceeds the Sale Price of a share of Common Stock on the Trading Day next succeeding the Expiration Time, the
Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the Expiration Time by a fraction, 
 (1) the numerator of which shall be the number of shares of Common Stock outstanding (including any tendered or exchanged shares) at the Expiration Time
multiplied by the Sale Price of a share of Common Stock on the Trading Day next succeeding the Expiration Time such adjustment to become effective immediately prior to the opening of business on the day following the Expiration Time; and 

(2) the denominator of which shall be the sum of (x) the Fair Market Value (determined as aforesaid) of the aggregate consideration payable to
stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed so accepted up to any such
maximum, being referred to as the “Purchased Shares”) and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares) at the Expiration Time and the Sale Price of a share of Common Stock on
the Trading Day next succeeding the Expiration Time. 
 If the Company is obligated to purchase shares pursuant to any such tender or
exchange offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price that would then be in effect if
such tender or exchange offer had not been made. 
  

 50 

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

“Current Market Price” on any date means the average of the daily Sale Prices per share of Common Stock for the ten consecutive
Trading Days immediately prior to such date; provided, however, that if: 
 (1) the “ex” date (as hereinafter defined) for any
event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 9.3(a), (b), (c), (d), (e) or (f) occurs during such ten consecutive Trading Days, the
Sale Price for each Trading Day prior to the “ex” date for such other event shall be adjusted by dividing such Sale Price by the same fraction by which the Conversion Price is so required to be adjusted as a result of such other event;

 (2) the “ex” date for any event (other than the issuance or distribution requiring such computation) that requires an
adjustment to the Conversion Price pursuant to Section 9.3(a), (b), (c), (d), (e) or (f) occurs on or after the “ex” date for the issuance or distribution requiring such computation and prior to the day in question, the Sale
Price for each Trading Day on and after the “ex” date for such other event shall be adjusted by dividing such Sale Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such
other event; and 
 (3) the “ex” date for the issuance or distribution requiring such computation is prior to the day in question,
after taking into account any adjustment required pursuant to clause (1) or (2) of this proviso, the Sale Price for each Trading Day on or after such “ex” date shall be adjusted by adding thereto the amount of any cash and the
Fair Market Value (as determined by the Board of Directors in a manner consistent with any determination of such value for purposes of Section 9.3(d), (e) or (f)) of the evidences of indebtedness, shares of capital stock or assets being
distributed applicable to one share of Common Stock as of the close of business on the day before such “ex” date. 
 For purposes
of any computation under Section 9.3(f), if the “ex” date for any event (other than the tender offer requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 9.3(a), (b), (c), (d),
(e) or (f) occurs on or after the Expiration Time for the tender or exchange offer requiring such computation and prior to the day in question, the Sale Price for each Trading Day on and after the “ex” date for such other event
shall be adjusted by dividing such Sale Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such other event. For purposes of this paragraph, the term “ex” date, when used:

 (1) with respect to any issuance or distribution, means the first date on which the shares of Common Stock trade regular way on the
relevant exchange or in the relevant market from which the Sale Price was obtained without the right to receive such issuance or distribution; 
 (2) with respect to any subdivision or combination of shares of Common Stock, means the first date on which the shares of Common Stock trade regular way on such exchange or in such market after the time at which such subdivision or
combination becomes effective; and 
  

 51 

 (3) with respect to any tender or exchange offer, means the first date on which the shares of Common
Stock trade regular way on such exchange or in such market after the Expiration Time of such offer. 
 Notwithstanding the foregoing,
whenever successive adjustments to the Conversion Price are called for pursuant to this Section 9.3, such adjustments shall be made to the Current Market Price as may be necessary or appropriate to effectuate the intent of this Section 9.3
and to avoid unjust or inequitable results as determined in good faith by the Board of Directors. 
 “Fair Market Value”
shall mean the amount that a willing buyer would pay a willing seller in an arm’s-length transaction (as determined by the Board of Directors, whose determination shall be conclusive). 
 “Record Date” shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of shares of
Common Stock have the right to receive any cash, securities or other property or in which the shares of Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date
fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise). 
 (h) The Company shall be entitled to make such additional reductions in the Conversion Price, in addition to those required by Section 9.3(a), (b),
(c), (d), (e) or (f), as shall be necessary in order that any dividend or distribution of Common Stock, any subdivision, reclassification or combination of shares of Common Stock or any issuance of rights or warrants referred to above shall not
be taxable to the holders of Common Stock for United States Federal income tax purposes. 
 (i) To the extent permitted by applicable law and
Section 8.1(e), the Company may, from time to time, reduce the Conversion Price by any amount for any period of time, if such period is at least 20 days and the reduction is irrevocable during the period. Whenever the Conversion Price is
reduced pursuant to the preceding sentence, the Company shall mail to the Trustee and each Holder at the address of such Holder as it appears in the register of the Securities maintained by the Registrar, at least 15 days prior to the date the
reduced Conversion Price takes effect, a notice of the reduction stating the reduced Conversion Price and the period during which it will be in effect. 
 (j) In any case in which this Section 9.3 shall require that any adjustment be made effective as of or retroactively immediately following a Record Date, the Company may elect to defer (but only for five Trading
Days following the filing of the statement referred to in Section 9.5) issuing to the Holder of any Securities converted after such Record Date the shares of Common Stock issuable upon such conversion over and above the shares of Common Stock
issuable upon such conversion on the basis of the Conversion Price prior to adjustment; provided, however, that the Company shall deliver to such Holder a due bill or other appropriate instrument evidencing such Holder’s right to receive such
additional shares upon the occurrence of the event requiring such adjustment. 
  

 52 

 (k) All calculations under this Section 9.3 shall be made to the nearest cent or one-ten-thousandth
of a share, with one-half cent and 0.00005 of a share, respectively, being rounded upward. 
 (l) In the event that at any time, as a result
of an adjustment made pursuant to this Section 9.3, the Holder of any Securities thereafter surrendered for conversion shall become entitled to receive any shares of stock of the Company other than shares of Common Stock into which the
Securities originally were convertible, the Conversion Price of such other shares so receivable upon conversion of any such Security shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the
provisions with respect to Common Stock contained in subparagraphs (a) through (k) of this Section 9.3, and the provision of Sections 9.1, 9.2 and 9.4 through 9.9 with respect to the Common Stock shall apply on like or similar terms
to any such other shares and the determination of the Board of Directors as to any such adjustment shall be conclusive. 
 (m) No adjustment
or payment shall be made (i) pursuant to Section 9.3(i) if the effect thereof would be to reduce the Conversion Price below $0.59, or (ii) pursuant to any provision of (a) this Section 9.3 if the Holders of the Securities may participate in the
transaction that otherwise would give rise to an adjustment pursuant to this Section 9.3 or (b) this Section 9.3 if the consent of the holders of the Common Stock would be required for the issuance of, or the Company’s agreement to issue,
the Common Stock at the adjusted Conversion Price pursuant to the rules of The Nasdaq Stock Market or any national or regional securities exchange or other market on which the Common Stock is then traded or quoted and the Company has not obtained
such consent in compliance with the applicable rules. If the consent of the holders of the Common Stock would be required for any increase in the number of shares issuable upon conversion of the Securities under Section 9.1(b) or the payment of any
portion of the Make-Whole Interest Payment under Section 9.1(d) pursuant to the rules of The Nasdaq Stock Market or any national or regional securities exchange or other market on which the Common Stock is then traded or quoted, then the Company
shall not be required to effect such increase or make such payment only to the extent that it would require approval of the holders of Common Stock, and the Company shall instead be required to either (i) obtain such consent of the holders of
the Common Stock or (ii) make alternative arrangements that do not require the consent of the holders of the Common Stock and that, but for this Section 9.3(m), would have an equivalent economic value as the number of shares that would have
been issuable upon conversion of the Securities under Section 9.1(b) or portion of the payment that would have been made pursuant to Section 9.1(d) under the circumstances set forth in Section 9.1(b) and 9.1(d), subject to such arrangements being
reasonably satisfactory to Holders of a majority in aggregate principal amount of the Securities at the time outstanding. 
 Section 9.4
Consolidation or Merger of the Company. If any of the following events occurs, namely: 
 (1) any reclassification or change of the
outstanding Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination) as a result of which holders of Common Stock shall be entitled to
receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock; 
 (2) any
merger, consolidation, statutory share exchange or combination of the Company with another corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with
respect to or in exchange for such Common Stock; or 
 (3) any sale or conveyance of the properties and assets of the Company as, or
substantially as, an entirety to any other corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock;

 the Company or the successor or purchasing corporation, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply
with the Trust Indenture Act as in force at the date of execution of such supplemental indenture, if such supplemental indenture is then required to so comply) providing that such Securities shall be convertible into the kind and amount of shares of
stock and other securities or property or assets (including cash) which such Holder 

  

 53 

 
would have been entitled to receive upon such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance had
such Securities been converted into Common Stock immediately prior to such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance assuming such holder of Common Stock did not exercise its rights of
election, if any, as to the kind or amount of securities, cash or other property receivable upon such merger, consolidation, statutory share exchange, sale or conveyance (provided, that if the kind or amount of securities, cash or other property
receivable upon such merger, consolidation, statutory share exchange, sale or conveyance is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised (the “Non-Electing
Share”), then for the purposes of this Section 9.4, the kind and amount of securities, cash or other property receivable upon such merger, consolidation, statutory share exchange, sale or conveyance for each Non-Electing Share shall be
deemed to be the kind and amount so receivable per share by a plurality of the Non-Electing Shares). Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for
in this Article IX. If, in the case of any such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, the stock or other securities and assets receivable thereupon by a holder of Common Stock
includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or
conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors shall reasonably consider
necessary by reason of the foregoing, including to the extent practicable the provisions providing for the conversion rights set forth in this Article IX. 
 The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at the address of such Holder as it appears on the register of the Securities maintained by the Registrar,
within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. 
 The above provisions of this Section 9.4 shall similarly apply to successive reclassifications, mergers, consolidations, statutory share exchanges, combinations, sales and conveyances. 
 If this Section 9.4 applies to any event or occurrence, Section 9.3 shall not apply. Notwithstanding this Section 9.4, if a Public
Acquirer Change of Control occurs and the Company elects to adjust the Conversion Price and its conversion obligation pursuant to Section 9.12, the provisions of Section 9.12 shall apply to the conversion instead of this Section 9.4.

 Any Additional Common Stock which a Holder is entitled to receive upon conversion pursuant to Section 9.1(b), if applicable, shall
not be payable in shares of Common Stock, but will represent a right to receive the aggregate amount of cash, securities or other property into which the Additional Common Stock would convert as a result of such recapitalization, consolidation,
merger, share transfer, acquisition or share exchange. 
 Section 9.5 Notice of Adjustment. Whenever an adjustment in the Conversion
Price with respect to the Securities is required: 
 (1) the Company shall forthwith place on file with the Trustee and any Conversion Agent
for such securities a certificate of the Treasurer of the Company, stating the adjusted Conversion Price determined as provided herein and setting forth in reasonable detail such facts as shall be necessary to show the reason for and the manner of
computing such adjustment; and 
  

 54 

 (2) a notice stating that the Conversion Price has been adjusted and setting forth the adjusted
Conversion Price shall forthwith be given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company, to each Holder in the manner provided in Section 11.2. Any notice so given shall be
conclusively presumed to have been duly given, whether or not the Holder receives such notice. 
 In addition, whenever an adjustment in the Conversion Price
with respect to the Securities is required, the Company will issue a press release through Dow Jones & Company, Inc. containing the relevant information and make this information available on the Company’s web site or through another
public medium as it may use at that time. 
 Section 9.6 Notice in Certain Events. In case: 
 (1) of a consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale or
conveyance to another Person or entity or group of Persons or entities acting in concert as a partnership, limited partnership, syndicate or other group (within the meaning of Rule 13d-3 under the Exchange Act) of all or substantially all of the
property and assets of the Company; or 
 (2) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; or

 (3) of any action triggering an adjustment of the Conversion Price referred to in clauses (x) or (y) below; 
 then, in each case, the Company shall cause to be filed with the Trustee and the Conversion Agent, and shall cause to be given, to the Holders of the Securities in the
manner provided in Section 11.2, at least 15 days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of any distribution or grant of rights or warrants
triggering an adjustment to the Conversion Price pursuant to this Article IX, or, if a record is not to be taken, the date as of which the holders of record of Common Stock entitled to such distribution, rights or warrants are to be determined, or
(y) the date on which any reclassification, consolidation, merger, sale, conveyance, dissolution, liquidation or winding up triggering an adjustment to the Conversion Price pursuant to this Article IX is expected to become effective, and the
date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger sale, conveyance, dissolution,
liquidation or winding up. 
 Failure to give such notice or any defect therein shall not affect the legality or validity of the proceedings
described in clause (1), (2) or (3) of this Section 9.6.

 Section 9.7 Company To Reserve Stock: Registration; Listing. 
 (a) The Company shall, in accordance with the laws of the State of Delaware, at all times reserve and keep available, free from preemptive rights, out of
its authorized but unissued shares of Common Stock, for the purpose of effecting the conversion of the Securities, such number of its duly authorized shares of Common Stock as shall from time to time be sufficient to effect the conversion of all
Securities then outstanding into such Common Stock at any time (assuming that, at the time of the computation of such number of shares or securities, all such Securities would be held by a single Holder); provided, however, that nothing contained
herein shall preclude the Company from satisfying its obligations in respect of the conversion of the Securities by delivery of purchased shares of Common Stock which are then held in the treasury of the Company. The Company covenants that all
shares of Common Stock which may be issued upon conversion of Securities will upon issue be fully paid and nonassessable and free from all liens and charges and, except as provided in Section 9.8, taxes with respect to the issue thereof.

 (b) If any shares of Common Stock which would be issuable upon conversion of Securities hereunder require registration with or approval of
any governmental authority before such shares or securities may be issued upon such conversion, the Company will in good faith and as expeditiously as possible endeavor to cause such shares or securities to be duly registered or approved, as the
case may be. The Company further covenants that so long as the Common Stock shall be listed on The Nasdaq Stock Market, Inc., the Company will, if permitted by the rules of such exchange, list and keep listed all Common Stock issuable upon
conversion of the Securities, and the Company will endeavor to list the shares of Common Stock required to be delivered upon conversion of the Securities prior to such delivery upon any other national securities exchange upon which the outstanding
Common Stock is listed at the time of such delivery. 
 Section 9.8 Taxes on Conversion. The issue of stock certificates on conversion
of Securities shall be made without charge to the converting Holder for any documentary, stamp or similar issue or transfer taxes in respect of the issue thereof, and the Company shall pay any and all documentary, stamp or similar issue or transfer
taxes that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Securities pursuant hereto. The Company shall not, however, be required to pay any such tax which may be payable in respect of any transfer
involved in the issue or delivery of shares of Common Stock or the portion, if any, of the Securities which are not so converted in a name other than that in which the Securities so converted were registered, and no such issue or delivery shall be
made unless and until the Person requesting such issue has paid to the Company the amount of such tax or has established to the satisfaction of the Company that such tax has been paid. 
 Section 9.9 Conversion After Interest Record Date. Except as provided below, if any Securities are surrendered for conversion on any day other
than an Interest Payment Date, the Holder of such Securities shall not be entitled to receive any interest that has accrued on such Securities since the prior Interest Payment Date. By delivery to the Holder of the number of shares of Common Stock
or other consideration issuable upon conversion in accordance with this Article IX, any accrued and unpaid interest on such Securities will be deemed to have been paid in full. 
 If any Securities are surrendered for conversion subsequent to the Interest Record Date preceding an Interest Payment Date but on or prior to such
Interest Payment Date, the Holder of such Securities at the close of business on such Interest Record Date shall receive the interest payable on such Securities on such Interest Payment Date notwithstanding the conversion thereof. Securities 

  

 56 

 
surrendered for conversion during the period from the close of business on any Interest Record Date preceding any Interest Payment Date to the opening of
business on such Interest Payment Date shall (except in the case of Securities which have been called for redemption on a Redemption Date which is after such Interest Record Date and on or prior to the third Business Day after such Interest Payment
Date) be accompanied by payment by Holders, for the account of the Company, in New York Clearing House funds or other funds of an amount equal to the interest payable on such Interest Payment Date on the Securities being surrendered for conversion.
Except as provided in Section 3.1 or this Section 9.9, no adjustments in respect of payments of interest on Securities surrendered for conversion or any dividends or distributions or interest on the Common Stock issued upon conversion
shall be made upon the conversion of any Securities. 
 Section 9.10 Company Determination Final. Any determination that the Company
or the Board of Directors must make pursuant to this Article IX shall be conclusive if made in good faith and in accordance with the provisions of this Article, absent manifest error, and set forth in a Board Resolution. 
 Section 9.11 Responsibility of Trustee for Conversion Provisions. The Trustee has no duty to determine when an adjustment under this Article IX
should be made, how it should be made or what it should be. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities. The Trustee shall not be responsible for any failure of the
Company to comply with this Article IX. Each Conversion Agent other than the Company shall have the same protection under this Section 9.11 as the Trustee. 
 The rights, privileges, protections, immunities and benefits given to the Trustee under the Indenture including, without limitation, its rights to be indemnified, are extended to, and shall be enforceable by, the
Trustee in each of its capacities hereunder, and each Paying Agent or Conversion Agent acting hereunder. 
 Section 9.12 Conversion After
a Public Acquirer Change of Control. 
 (a) In the event of a Public Acquirer Change of Control, the Company may, in lieu of issuing the
Additional Common Stock pursuant to Section 9.1(b), elect to adjust the Conversion Price and the related conversion obligation such that from and after the Effective Date of such Public Acquirer Change of Control, Holders of the Security will
be entitled to convert their Security, in accordance with Section 9.2 hereof, into a number of shares of Public Acquirer Common Stock by adjusting the Conversion Price in effect immediately before the Public Acquirer Change of Control by
multiplying it by a fraction: 
 (1) the numerator of which will be the average of the Sale Prices of the Public Acquirer Common Stock for
the five consecutive Trading Days commencing on the Trading Day next succeeding the effective date of such Public Acquirer Change of Control, and 
 (2) the denominator of which will be (A) in the case of a share exchange, consolidation, merger or binding share exchange, pursuant to which the Common Stock is converted into cash, securities or other property, the average value of
all cash and any other consideration (as determined by the Board of Directors) paid or payable per share of Common Stock or (B) in the case of any other Public Acquirer Change of Control, the average of the Sale Price of the Common Stock for
the five consecutive Trading Days prior to but excluding the Effective Date of such Public Acquirer Change of Control. 
  

 57 

 (b) The Company will notify Holders of its election by providing notice as set forth in
Section 9.1(c). 
 ARTICLE X. 
 SATISFACTION AND DISCHARGE OF INDENTURE 
 Section 10.1 Satisfaction and Discharge of Indenture. This Indenture shall

of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when 
 (1) either 

(A) all Securities theretofore authenticated and delivered (other than (i) Securities which have been destroyed, lost or stolen and which have
been replaced or paid as provided in Section 2.7 and (ii) Securities for whose payment money has theretofore been deposited in trust and thereafter repaid to the Company as provided in Section 10.3) have been delivered to the Trustee
for cancellation; or 
 (B) all such Securities not theretofore delivered to the Trustee for cancellation have become due and payable and
the Company has irrevocably deposited or caused to be irrevocably deposited cash with the Trustee or a Paying Agent (other than the Company or any of its Affiliates) as trust funds in trust for the purpose of and in an amount sufficient to pay and
discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal, interest and Make-Whole Interest Payment, if any, to the date of such deposit (in the case of Securities which have become
due and payable); 
 (2) no Default or Event of Default has occurred and is continuing on the date of such deposit and the deposit will not
result in a breach or violation of, or constitute a default under, any other instrument to which the Company is a party or by which the Company is bound; 
 (3) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and 
 (4)
the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein relating to the satisfaction and discharge of this Indenture have been complied with. 
 Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 7.7 shall survive and,
if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (1) of this Section, the provisions of Sections 2.3 through 2.7, Article III, Article IX, the last sentence of Section 4.2 and this Article X,
shall survive until the Securities have been paid in full.

Trustee or a Paying Agent shall hold in trust, for the benefit of the Holders, all money deposited with it pursuant to Section 10.1 and shall apply the deposited money in accordance with this Indenture and the Securities to the payment of the
principal of, interest on and Make-Whole Interest Payment, if any, on the Securities.

Trustee and each Paying Agent shall promptly pay to the Company upon request any excess money (i) deposited with them pursuant to Section 10.1 and (ii) held by them at any time.

Interest Payment, if any, that remains unclaimed for two years after a right to such money has matured; provided, however, that the Trustee or such Paying Agent, before being required to make any such payment, may at the expense of the Company cause
to be mailed to each Holder entitled to such money notice that such money remains unclaimed and that after a date specified therein, which shall be at least 30 days from the date of such mailing, any unclaimed balance of such money then remaining
will be repaid to the Company. After payment to the Company, Holders entitled to money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person. 
 Section 10.4 Reinstatement. If the Trustee or any Paying Agent is unable to apply any money in accordance with Section 10.2 by reason of
any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture and the Securities shall be
revived and reinstated as though no deposit had occurred pursuant to Section 10.1 until such time as the Trustee or such Paying Agent is permitted to apply all such money in accordance with Section 10.2; provided, however, that if the
Company has made any payment of the principal of, interest on or Make-Whole Interest Payment, if any, on any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities
to receive any such payment from the money held by the Trustee or such Paying Agent.

 [FORM OF REVERSE OF GLOBAL SECURITY] 
 3.125% CONVERTIBLE SENIOR NOTES DUE MAY 1, 2013 
 This Security is one of a duly
authorized issue of the 3.125% Convertible Senior Notes due May 1, 2013 (the “Securities”) of Cell Genesys, Inc., a Delaware corporation (including any successor corporation under the Indenture hereinafter referred to, the
“Company”), issued under an Indenture, dated as of June 24, 2009 (the “Indenture”), 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 (“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, in the event of any inconsistency between the terms of this Security and the terms of the Indenture, the terms of the
Indenture shall control. Capitalized terms used but not otherwise defined herein have the meanings assigned to them in the Indenture unless otherwise indicated. 
  

	1.	Interest. 

 The Company promises to pay interest on the
principal amount of the Securities at the interest rate of 3.125% (the “Interest Rate”) from the date of issuance until repayment in full at May 1, 2013, or until an earlier conversion, redemption or repurchase. The Company
will pay interest on this Security semi-annually in arrears on May 1 and November 1 of each year (each, an “interest payment date”), commencing November 1, 2009. 
 The Securities shall bear interest from June 24, 2009 until the principal amount thereof is paid or made available for payment, or until such date on
which the Securities are converted, redeemed or purchased as provided herein at a rate of 3.125% per annum. 
 Interest on the
Securities shall be computed (i) for any full semi-annual period for which a particular Interest Rate is applicable, on the basis of a 360-day year of twelve 30-day months and (ii) for any period for which a particular Interest Rate is
applicable for less than a full semiannual period for which interest is calculated, on the basis of a 30-day month and, for such periods of less than a month, the actual number of days elapsed over a 30-day month. 
 If this Security is redeemed or repurchased by the Company on a date that is after the record date and on or prior to the corresponding interest payment
date, interest accrued and unpaid hereon to but not including the applicable Redemption Date or Fundamental Change Purchase Date, as the case may be, will be paid to the same Holder to whom the Company pays the principal of this Security.

 Interest on Securities converted after a record date but prior to the corresponding interest payment date will be paid to the Holder of
the Securities on the record date but, upon conversion, the Holder must pay the Company the interest which have accrued and will be paid on such interest payment date; provided, that no such payment need be made with respect to Securities which will
be redeemed by the Company after a record date and on or prior to the third Business Day after the corresponding interest payment date. 
  

 A-3 

 If the principal amount hereof or any portion of such principal amount or any interest on any Security is
not paid when due (whether upon acceleration pursuant to Section 6.2 of the Indenture, upon the date set for payment of the Redemption Price pursuant to Section 5 hereof or the Fundamental Change Purchase Price pursuant to Section 6
hereof or upon the Stated Maturity of this Security), then in each such case the overdue amount shall, to the extent permitted by law, bear interest at the Interest Rate, compounded semi-annually, which interest shall accrue from the date on which
such overdue amount was originally due until the date on which payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be payable on demand. 
  

	2.	Method of Payment. 

 Except as provided below, interest
will be paid (i) on the Global Securities to The Depository Trust Company (“DTC”) or its nominee in immediately available funds, (ii) on any definitive Securities having an aggregate principal amount of $2,000,000 or less,
by check mailed to the Holders of such Securities, and (iii) on any definitive Securities having an aggregate principal amount of more than $2,000,000, by wire transfer in immediately available funds at the election of the Holders of such
Securities. 
 At Stated Maturity, the Company will pay interest on definitive Securities at the Company’s office or agency in New York
City, which initially will be the corporate trust office of U.S. Bank Trust National Association, an Affiliate of the Trustee in New York City. 
 Principal on Global Securities will be paid to DTC or its nominee in immediately available funds. Principal on definitive Securities will be payable, upon Stated Maturity or when due, at the office or agency of the Company in New York City,
maintained for such purpose, initially the corporate trust office of U.S. Bank Trust National Association, an Affiliate of the Trustee in New York City. 
 Subject to the terms and conditions of the Indenture, the Company will make payments in cash in respect of Redemption Prices, Fundamental Change Purchase Prices, and Make-Whole Interest Payment, if any, and at Stated
Maturity to Holders who surrender Securities to a Paying Agent to collect such payments in respect of the Securities. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public
and private debts. However, the Company may make such cash payments by check payable in such money. 
  

	3.	Paying Agent, Conversion Agent and Registrar. 

 Initially,
U.S. Bank National Association will act as Paying Agent, Conversion Agent and Registrar. The Company may appoint and change any Paying Agent, Conversion Agent or Registrar without notice, other than notice to the Trustee; provided that the Company
will maintain at least one Paying Agent in the State of New York, City of New York, Borough of Manhattan, which shall initially be an office or agency of the Trustee. The Company or any of its Subsidiaries or any of their Affiliates may act as
Paying Agent, Conversion Agent or Registrar. 
  

 A-4 

	4.	Indenture. 

 The Securities are senior unsecured
obligations of the Company limited to $20,783,000 aggregate principal amount. The Indenture does not limit other indebtedness of the Company, secured or unsecured. 
  

	5.	Redemption at the Option of the Company. 

 No sinking fund
is provided for the Securities. The Securities are not redeemable by the Company prior to May 1, 2011. If the Sale Price of the Common Stock has exceeded 150% of the Conversion Price then in effect for at least 20 Trading Days in any period of
30 consecutive Trading Days ending on the Trading Day prior to the mailing of the Redemption Notice, the Securities will be redeemable for cash at the option of the Company, in whole or in part, at any time or from time to time, on or after
May 1, 2011 upon not less than 20 nor more than 60 days’ notice by mail for a redemption price equal to the principal amount of those Securities plus accrued and unpaid interest on those Securities (including Securities which are converted
into Common Stock under certain circumstances specified in the Indenture) up to the Redemption Date (the “Redemption Price”). 
  

	6.	Purchase By the Company at the Option of the Holder. 

 At
the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to offer to purchase the Securities held by such Holder within 30 days after the occurrence of a Fundamental Change for a
Fundamental Change Purchase Price equal to the principal amount plus accrued and unpaid interest of such Security on the Fundamental Change Purchase Date. The Fundamental Change Purchase Date shall be between 30 and 60 days of the Company’s
delivery of the notice described in the preceding sentence. The Fundamental Change Purchase Price shall be paid in cash. 
 Holders have the
right to withdraw any Fundamental Change Purchase Notice, as the case may be, by delivering to the Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture. 
 If cash sufficient to pay the Fundamental Change Purchase Price of all Securities, or portions thereof to be purchased as of the Fundamental Change
Purchase Date, is deposited with the Paying Agent on the Business Day following the Fundamental Change Purchase Date, interest will cease to accrue on such Securities (or portions thereof) immediately after such Fundamental Change Purchase Date, and
the Holder thereof shall have no other rights as such other than the right to receive the Fundamental Change Purchase Price upon surrender of such Security. 
  

	7.	Notice of Redemption. 

 Notice of redemption pursuant to
Section 5 of this Security will be mailed at least 20 days but not more than 60 days before the Redemption Date to each Holder of Securities to be redeemed at the Holder’s registered address. If money sufficient to pay the Redemption Price
of all Securities (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent prior to or on the Redemption Date, immediately after such Redemption Date interest ceases to accrue on such Securities or portions
thereof. Securities in denominations larger than $1,000 of principal amount may be redeemed in part but only in integral multiples of $1,000 of principal amount. 
  

 A-5 

	8.	Conversion. 

 Subject to and in compliance with the
provisions of the Indenture, a Holder is entitled, at such Holder’s option, to convert the Holder’s Security (or any portion of the principal amount thereof that is $1,000 or an integral multiple of $1,000), into fully paid and
nonassessable shares of Common Stock at the Conversion Price in effect at the time of conversion. 
 A Security in respect of which a Holder
has delivered a Fundamental Change Purchase Notice, exercising the option of such Holder to require the Company to purchase such Security, may be converted only if such Change of Control Purchase Notice is withdrawn in accordance with the terms of
the Indenture. 
 The initial Conversion Price is $0.68, subject to adjustment in certain events described in the Indenture. Upon conversion
of this Security under certain circumstances as described in the Indenture, the Company will make certain Make-Whole Interest Payment on this Security as described in the Indenture. No fractional shares of Common Stock shall be issued upon
conversion of any Security. A Holder that surrenders Securities for conversion will receive cash or a check in lieu of any fractional share of Common Stock. 
 To surrender a Security for conversion, a Holder must (i) complete and manually sign the conversion notice below (or complete and manually sign a facsimile of such notice) and deliver such notice to the
Conversion Agent, (ii) surrender the Security to the Conversion Agent, (iii) furnish appropriate endorsements and transfer documents and (iv) pay any transfer or similar tax, if required by the Indenture. 
 If the Company (i) is a party to a consolidation, merger or binding share exchange, (ii) reclassifies the Common Stock or (iii) conveys,
transfers or leases its properties and assets substantially as an entirety to any Person, the right to convert a Security into shares of Common Stock may be changed into a right to convert it into securities, cash or other assets of the Company or
such other Person, in each case in accordance with the Indenture. 
  

	9.	Denominations; Transfer; Exchange.
