shall register the transfer or make the exchange if its requirements under this Indenture for such transaction are met. To permit registrations of transfer and exchanges, the Trustee shall authenticate Securities at the Registrar’s request or upon the Trustee’s receipt of a Company Order therefor. The Company, the Registrar or the Trustee, as the case may be, shall not be required to register the transfer of or exchange any Security for which a Repurchase Notice or notice of redemption pursuant to Article 11 has been delivered, and not withdrawn, in accordance with this Indenture, except if the Company has defaulted in the payment of the Fundamental Change Repurchase Price or the Redemption Price with respect to such Security or to the extent that a portion of such Security is not subject to such Repurchase Notice or notice of redemption.

No service charge shall be made for any transfer, exchange or conversion of Securities, but the Company and the Trustee may require payment of a sum sufficient to cover any documentary, stamp, issue or transfer tax or similar governmental charge that may be imposed in connection with any transfer, exchange or conversion of Securities, other than exchanges pursuant to Section 2.07, Section 2.10, Section 3.01, Section 9.04 or Section 10.02, in each case, not involving any transfer.

Section 2.07. Replacement Securities. If the Holder of a Security claims that the Security has been mutilated, lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate, at the Holder’s expense, a replacement Security upon surrender to the Trustee of the mutilated Security, or upon delivery to the Trustee of evidence of the loss, destruction or theft of the Security satisfactory to the Trustee and the Company. In the case of a lost, destroyed or wrongfully taken Security, if required by the Trustee or the Company, indemnity (including in the form of a bond) must be provided by the Holder that is reasonably satisfactory to the Trustee and the Company to indemnify and hold harmless the Company, the Trustee or any Securities Agent from any loss that any of them may suffer if such Security is replaced.

In case any such mutilated, lost, destroyed or wrongfully taken Security has become due and payable, the Company in its discretion may, instead of issuing a new Security, pay the amounts due in respect of such Security as provided hereunder.

Every replacement Security is an additional obligation of the Company only as provided in Section 2.08.

Section 2.08. Outstanding Securities. Securities outstanding at any time are all the Securities authenticated by the Trustee except for those converted, those cancelled by it, those delivered to it for cancellation and those described in this Section 2.08 as not outstanding. Except to the extent provided in Section 2.09, a Security does not cease to be outstanding because the Company or one of its Subsidiaries or Affiliates holds the Security.

If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it, or a court holds, that the replaced Security is held by a protected purchaser.

15

If the Paying Agent (in the case of a Paying Agent other than the Company) holds, as of 10:00 a.m. New York City time on a Fundamental Change Repurchase Date or a Redemption Date or the Maturity Date, money sufficient to pay the aggregate Fundamental Change Repurchase Price, Redemption Price or principal amount (plus accrued and unpaid interest, if any), as the case may be, with respect to all Securities to be repurchased or paid on such Fundamental Change Repurchase Date or Redemption Date or the Maturity Date, as the case may be, in each case, payable as herein provided on such Fundamental Change Repurchase Date or Redemption Date or the Maturity Date, then (unless there shall be a Default in the payment of such aggregate Fundamental Change Repurchase Price, Redemption Price or principal amount, or of such accrued and unpaid interest), except as otherwise provided herein, then on and after such date such Securities shall be deemed to be no longer outstanding, interest on such Securities shall cease to accrue, and such Securities shall be deemed to be paid whether or not such Securities are delivered to the Paying Agent. Thereafter, all rights of the Holders of such Securities shall terminate with respect to such Securities, other than the right to receive the Fundamental Change Repurchase Price, Redemption Price or principal amount, as the case may be, plus, if applicable, such accrued and unpaid interest in accordance with this Indenture.

If a Security is converted in accordance with Article 10 then, from and after the time of such conversion on the Conversion Date, such Security shall cease to be outstanding, and interest, if any, shall cease to accrue on such Security unless there shall be a Default in the payment or delivery of the consideration payable and/or deliverable hereunder upon such conversion (except that any such Security will remain outstanding solely for the purpose of receiving any interest or other amounts due following such conversion as set forth in this Indenture).

Section 2.09. Securities Held by the Company or an Affiliate . In determining whether the Holders of the required aggregate principal amount of Securities have concurred in any direction, waiver or consent with respect to this Indenture or the Securities, Securities owned by the Company or any of its Subsidiaries or Affiliates (other than Atairos Management, L.P. or any of its Affiliates) shall be considered as though not outstanding, except that, for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities that a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. Securities so owned which have been pledged in good faith may be considered to be outstanding for purposes of this Section 2.09 if the pledgee establishes, to the satisfaction of the Trustee, the pledgee’s right to so concur with respect to such Securities and that the pledgee is not, and is not acting at the direction or on behalf of, the Company, any other obligor on the Securities, an Affiliate of the Company (other than Atairos Management, L.P. or any of its Affiliates) or an Affiliate of any such other obligor (other than Atairos Management, L.P. or any of its Affiliates). In case of a dispute as to whether the pledgee has established the foregoing, any decision by the Trustee taken upon the advice of counsel shall provide full protection to the Trustee. The Company shall furnish to the Trustee an Officers’ Certificate listing and identifying all Securities, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Securities not listed therein are outstanding for the purpose of any such determination. For the avoidance of doubt and notwithstanding Section 316(a)(1) of the TIA or anything herein to

16

the contrary, no Atairos Securities shall be deemed to be owned by the Company or any of its Subsidiaries or Affiliates for purposes of this Indenture, the Securities and any direction, waiver or consent with respect thereto.

Section 2.10. Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and the Trustee, upon receipt of a Company Order therefor, shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee, upon receipt of a Company Order therefor, shall authenticate definitive Securities in exchange for temporary Securities. Until so exchanged, each temporary Security shall in all respects be entitled to the same benefits under this Indenture as definitive Securities, and such temporary Security shall be exchangeable for definitive Securities in accordance with the terms of this Indenture.

Section 2.11. Cancellation . The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar, Paying Agent and Conversion Agent shall forward to the Trustee any Securities surrendered to them for transfer, exchange, payment or conversion. The Trustee shall promptly cancel all Securities surrendered for transfer, exchange, payment, conversion or cancellation in accordance with its customary procedures. The Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation or that any Holder has converted pursuant to Article 10. All cancelled Securities held by the Trustee shall be disposed of in accordance with its customary procedure for the disposal of cancelled securities.

Section 2.12. Defaulted Interest. If, and to the extent, the Company defaults in a payment of interest on the Securities, the Company shall pay in cash the defaulted interest in any lawful manner plus, to the extent not prohibited by applicable statute or case law, interest on such defaulted interest at the rate provided in the Securities. The Company may pay the defaulted interest (plus interest on such defaulted interest) to the Persons who are Holders on a subsequent special record date. The Company shall fix such special record date and payment date. At least fifteen (15) calendar days before the special record date, the Company shall send to Holders and the Trustee a notice that states the special record date, payment date and amount of interest to be paid. Upon the due payment in full of such defaulted interest plus any interest thereon, interest shall no longer accrue on such defaulted interest pursuant to this Section 2.12.

Section 2.13. CUSIP Numbers . The Company in issuing the Securities may use one or more “CUSIP” numbers, and, if so, the Trustee shall use the CUSIP numbers in notices as a convenience to Holders; provided , however , that no representation is hereby deemed to be made by the Trustee as to the correctness or accuracy of the CUSIP numbers printed on the notice or on the Securities; and provided further that reliance may be placed only on the other identification numbers printed on the Securities, and the effectiveness of any such notice shall not be affected by any defect in, or omission of, such CUSIP numbers. The Company shall promptly notify the Trustee in writing of any change in the CUSIP numbers.

17

On the Issue Date, the Securities shall initially bear the CUSIP and ISIN numbers set forth in the following sentence. The CUSIP and ISIN numbers for the Atairos Global Securities that are Restricted Global Securities shall be 399473 AC1 and US399473AC18, respectively; the CUSIP and ISIN numbers for the Atairos Global Securities that are Unrestricted Global Securities shall be 399473 AD9 and US399473AD90, respectively; the CUSIP and ISIN numbers for Restricted Global Securities other than Atairos Global Securities shall be 399473 AA5 and US399473AA51, respectively; and the CUSIP and ISIN numbers for Unrestricted Global Securities other than Atairos Global Securities shall be 399473 AB3 and US399473AB35, respectively.

Section 2.14. Deposit of Moneys. Prior to 10:00 a.m., New York City time, on each Interest Payment Date, the Maturity Date or any Fundamental Change Repurchase Date or Redemption Date, the Company shall deposit with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust in accordance with Section 2.04) money, in funds immediately available on such date, sufficient to make cash payments, if any, due on such Interest Payment Date, the Maturity Date or such Fundamental Change Repurchase Date or Redemption Date, as the case may be, in a timely manner which permits the Paying Agent to remit payment to the Holders on such Interest Payment Date, the Maturity Date or such Fundamental Change Repurchase Date or Redemption Date, as the case may be.

If any Interest Payment Date, the Maturity Date or any Fundamental Change Repurchase Date or Redemption Date falls on a date that is not a Business Day, the payment due on such Interest Payment Date, the Maturity Date or such Fundamental Change Repurchase Date or Redemption Date, as the case may be, shall be postponed until the next succeeding Business Day, and no interest or other amount shall accrue as a result of such postponement.

Section 2.15. Book-Entry Provisions for Global Securities. (a) Global Securities initially shall (i) be registered in the name of the Depository, its successors or their respective nominees, (ii) be delivered to the Trustee as custodian for the Depository, its successors or their respective nominees, as the case may be, and (iii) bear the legends that such Global Securities are required to bear under Section 2.17.

Members of, or participants in, the Depository (“ Participants ”) shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depository, or the Trustee as its custodian, or under the Global Security, and the Depository (or its nominee) may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of the Global Security for all purposes whatsoever; provided , however , that each Atairos Global Security shall be subject to the rights under Section 9.02, Section 10.02(c) and Section 13.01 of the beneficial owners of such Atairos Global Security. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee, any Securities Agent or any of their respective agents from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and Participants, the operation of customary practices governing the exercise of the rights of a Holder of any Security.

18

(b) Except as otherwise set forth in this Section 2.15 or Section 2.16, transfers of Global Securities shall be limited to transfers in whole, but not in part, to the Depository, its successors or their respective nominees. In addition, one or more Physical Securities shall be transferred to each owner of a beneficial interest in a Global Security, as identified by the Depository, in exchange for its beneficial interest in the Global Securities if (i) the Depository notifies the Company that the Depository is unwilling or unable to continue as depository for any Global Security, or the Depository ceases to be a “clearing agency” registered under Section 17A of the Exchange Act, and, in either case, a successor Depository is not appointed by the Company within ninety (90) days of such notice or cessation or (ii) an Event of Default has occurred and is continuing and the Registrar has received a written request from the beneficial owner (via the Depository) of the relevant Securities to issue Physical Securities. For the avoidance of doubt, if any event described in clause (i) of the immediately preceding sentence occurs, any owner of a beneficial interest in any Global Security will be entitled to receive one or more Physical Securities in exchange for its beneficial interest or interests in the Global Securities, and if any event described in clause (ii) of the immediately preceding sentence occurs, only the beneficial owner that has made a written request to the Registrar (via the Depository) will be entitled to receive one or more Physical Securities in exchange for its beneficial interest or interests in the Global Securities. The Company may also exchange beneficial interests in a Global Security for one or more Physical Securities registered in the name of the owner of beneficial interests if the Company and the owner of such beneficial interests agree to so exchange.

(c) The transfer and exchange of beneficial interests in the Global Securities shall be effected through the Depository, in accordance with the provisions of this Indenture and the Applicable Procedures. Transfers of beneficial interests in the Global Securities also shall require compliance with either subparagraph (i) or (ii) below, as applicable, as well as, to the extent applicable, the other provisions of this Section 2.15(c) that follow:

(i) Transfer of Beneficial Interests in the Same Global Security . Beneficial interests in any Restricted Global Security may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Restricted Global Security (or a Restricted Global Security with the same CUSIP number) in accordance with the transfer restrictions set forth in the Security Private Placement Legend. Beneficial interests in any Unrestricted Global Security may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Unrestricted Global Security (or an Unrestricted Global Security with the same CUSIP number). No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this clause (i).

(ii) All Other Transfers and Exchanges of Beneficial Interests in Global Securities . In connection with all transfers and exchanges of a beneficial interest in a Global Security that are not addressed by Section 2.15(c)(i), there must be delivered (A) such instruction or order from a Participant or an Indirect Participant to the Depository, as may be required by the Applicable Procedures, directing the Depository to credit or cause to be credited a beneficial interest in another Global Security in an amount equal to the beneficial interest to be transferred or exchanged and (B) instructions given in

19

accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase. Upon satisfaction of all of the requirements for transfer or exchange of beneficial interests in a Global Security contained in this Indenture, the Trustee shall adjust the principal amount of the Global Securities pursuant to Section 2.15(d).

(iii) Transfer and Exchange of Beneficial Interests in a Restricted Global Security for Beneficial Interests in an Unrestricted Global Security . A beneficial interest in any Restricted Global Security may be exchanged by any holder thereof for a beneficial interest in an Unrestricted Global Security or transferred to a Person who takes delivery thereof in the form of a beneficial interest in an Unrestricted Global Security if the exchange or transfer complies with the requirements of this Section 2.15(c) and the Registrar receives the following:

(A) if the holder of such beneficial interest in a Restricted Global Security proposes to exchange such beneficial interest for a beneficial interest in an Unrestricted Global Security, a certificate from such Holder substantially in the form of Exhibit E ; or

(B) if the holder of such beneficial interest in a Restricted Global Security proposes to transfer such beneficial interest to a Person who shall take delivery thereof in the form of a beneficial interest in an Unrestricted Global Security, a certificate from such holder in the form of Exhibit D ;

and, in each such case set forth in this clause (iii) (other than an exchange or transfer pursuant to an effective registration statement of the Company or Rule 144 under the Securities Act), if the Registrar so requests or if the Applicable Procedures so require, an Opinion of Counsel in form reasonably acceptable to the Company to the effect that no registration under the Securities Act is required in connection with such exchange or transfer of beneficial interests to the relevant Person or in connection with any re-sales of the beneficial interests in the Unrestricted Global Security that are beneficially owned by such Person on the date of such opinion.

Beneficial interests in an Unrestricted Global Security cannot be exchanged for, or transferred to Persons who take delivery thereof in the form of, a beneficial interest in a Restricted Global Security.

(iv) Transfer and Exchange of Beneficial Interests in one Restricted Global Security for Beneficial Interests in another Restricted Global Security . A beneficial interest in any Restricted Global Security may be exchanged by any holder thereof for a beneficial interest in a Restricted Global Security with a different CUSIP number or different legends or transferred to a Person who takes delivery thereof in the form of a beneficial interest in a Restricted Global Security with a different CUSIP number or different legends if the exchange or transfer complies with the requirements of this Section 2.15(c) and the Registrar receives the following:

(A) if the holder of such beneficial interest in a Restricted Global Security proposes to exchange such beneficial interest for a beneficial interest in a Restricted Global Security with a different CUSIP number or different legends, a certificate from such Holder substantially in the form of Exhibit E ; or

20

(B) if the holder of such beneficial interest in a Restricted Global Security proposes to transfer such beneficial interest to a Person who shall take delivery thereof in the form of a beneficial interest in a Restricted Global Security with a different CUSIP number or different legends, a certificate from such holder in the form of Exhibit D .

Notwithstanding the foregoing or anything to the contrary provided herein, a holder of a beneficial interest in a Security that is not an Atairos Security may not exchange or transfer such beneficial interest for a beneficial interest in an Atairos Security.

(d) At such time as all beneficial interests in a particular Global Security have been exchanged for Physical Securities or a particular Global Security has been repurchased or canceled in whole and not in part, each such Global Security shall be returned to or retained and canceled by the Trustee in accordance with Section 2.11. At any time prior to such cancellation, if any beneficial interest in a Global Security is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Security or for Physical Securities, the principal amount of Securities represented by such Global Security shall be reduced accordingly and an endorsement shall be made on such Global Security by the Trustee or by the Depository at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Security, such other Global Security shall be increased accordingly and an endorsement shall be made on such Global Security by the Trustee or by the Depository at the direction of the Trustee to reflect such increase.

(e) In connection with the transfer of a Global Security in its entirety to beneficial owners pursuant to Section 2.15(b), such Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall upon written instructions from the Company authenticate and deliver, to each beneficial owner identified by the Depository in exchange for its beneficial interest in such Global Security, an equal aggregate principal amount of Physical Securities of authorized denominations.

(f) Any Physical Security delivered in exchange for an interest in a Global Security pursuant to Section 2.15(b), shall bear the same legend(s), if any, from Exhibit B-1A that are borne by the relevant Global Security, except to the extent the requirements of Section 2.15(c)(iii) or Section 2.15(c)(iv) are satisfied with respect to the removal or addition of any legend, mutatis mutandis for the fact that a Physical Security is being issued rather than a beneficial interest in a Global Security.

21

(g) The Holder of any Global Security may grant proxies and otherwise authorize any Person, including Participants and Persons that may hold interests through Participants, to take any action which a Holder is entitled to take under this Indenture or the Securities.

(h) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on the transfer of any interest in any Securities imposed under this Indenture or under applicable law (including any transfers between or among Participants or beneficial owners of interests in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

(i) Neither the Trustee nor any Securities Agent shall have any responsibility for any actions taken or not taken by the Depository.

(j) No service charge shall be made to or by a holder of a beneficial interest in a Global Security or to or by a Holder of a Physical Security for any registration of transfer or exchange.

(k) All Global Securities and Physical Securities issued upon any registration of transfer or exchange of Global Securities or Physical Securities shall evidence the same debt of the Company and shall be entitled to the same benefits under this Indenture as the Global Securities or Physical Securities surrendered upon such registration of transfer or exchange.

(l) Prior to due presentment for the registration of a transfer of any Security, the Trustee and the Company may deem and treat the Person in whose name any Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of and interest on such Securities and, subject to Section 2.09, for all other purposes, and neither of the Trustee or the Company shall be affected by notice to the contrary.

(m) Upon surrender for registration of transfer of any Security at the office or agency of the Company designated pursuant to Section 4.02, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more replacement Securities of any authorized denomination or denominations of a like aggregate principal amount.

(n) 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 at such office or agency. Whenever any Global Securities or Physical Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and send, the replacement Global Securities and Physical Securities which the Holder making the exchange is entitled to in accordance with the provisions of Section 2.02.

(o) Neither the Trustee nor any Securities Agent shall have any responsibility or obligation to any beneficial owner of an interest in the Global Securities, an agent member of,

22

or a participant in, the Depository or other person with respect to the accuracy of the records of the Depository or its nominees or of any Participant or member thereof, with respect to any ownership interest in the Global Securities or with respect to the delivery to any Participant, agent member, beneficial owner or other Person (other than the Depository) of any notice (including any notice of redemption) or the payment of any amount or delivery of any Securities (or other security or property) under or with respect to such Securities. The rights of beneficial owners in any Global Securities shall be exercised only through the Depository, subject to its applicable rules and procedures. The Trustee and each agent may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its agent members and Participants and any beneficial owners of Global Securities.

Section 2.16. Special Transfer Provisions . (a) Notwithstanding any other provisions of this Indenture, but except as provided in Section 2.15(b), a Global Security may not be transferred except as a whole by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository.

(b) Upon the transfer, exchange or replacement of Securities not bearing the Security Private Placement Legend, unless the Company notifies the Trustee in writing otherwise, the Trustee shall deliver Securities that do not bear the Security Private Placement Legend. Upon the transfer, exchange or replacement of Securities bearing the Security Private Placement Legend, the Trustee shall deliver only Securities that bear the Security Private Placement Legend unless (i) the requested transfer, exchange or replacement is after the Resale Restriction Termination Date, (ii) there is delivered to the Trustee and the Company an Opinion of Counsel reasonably satisfactory to the Company and addressed to the Company to the effect that no registration under the Securities Act is required in connection with such transfer, exchange or replacement of such Securities in connection with any re-sales of such Securities on the date of such opinion, (iii) such Security has been sold pursuant to an effective registration statement under the Securities Act and the Holder selling such Securities has delivered to the Registrar a notice in the form of Exhibit C hereto or (iv) such Security has been sold pursuant to Rule 144 under the Securities Act and the Holder selling such Securities has delivered to the Registrar a notice in the form of Exhibit D  hereto.

(c) By its acceptance of any Security or any Common Stock bearing the Security Private Placement Legend or the Common Stock Private Placement Legend, each holder thereof acknowledges the restrictions on transfer of such security set forth in this Indenture and in the Security Private Placement Legend or Common Stock Private Placement Legend, as applicable, and agrees that it will transfer such security only as provided in this Indenture and as permitted by applicable law.

The Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 2.15 or this Section 2.16 in accordance with its customary document retention policies. The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Registrar.

23

(d) The Company may, to the extent permitted by law, purchase the Securities in the open market or by tender offer at any price or by private agreement without giving prior notice to Holders. The Company may, at its option, surrender to the Trustee for cancellation any Securities the Company purchases in this manner. Securities surrendered to the Trustee for cancellation may not be reissued or resold and shall be promptly cancelled pursuant to Section 2.11.

Section 2.17. Restrictive Legends .

(a) Each Global Security and Physical Security that constitutes a Restricted Security shall bear the legend (the “ Security Private Placement Legend ”) as set forth in Exhibit B-1A on the face thereof until the date such Securities no longer constitute Restricted Securities as reasonably determined by the Company in good faith (but, in any event, no later than the first anniversary of the Issue Date) and evidenced by an Officers’ Certificate (such date, the “ Resale Restriction Termination Date ”).

No transfer of any Restricted Security prior to the Resale Restriction Termination Date will be registered by the Registrar unless the applicable box on the Form of Assignment has been checked.

Any Security (or security issued in exchange or substitution therefor) (i) as to which such restrictions on transfer shall have expired in accordance with their terms, (ii) that has been transferred pursuant to a registration statement that has become effective or been declared effective under the Securities Act and that continues to be effective at the time of such transfer or (iii) that has been sold pursuant to Rule 144 under the Securities Act or any similar provision then in force, may, upon surrender of such Security for exchange to the Trustee in accordance with the provisions of this Article 2, be exchanged for a new Security or Securities, of like tenor and aggregate principal amount, which shall not bear the Security Private Placement Legend required by this Section 2.17(a) and shall not be assigned a restricted CUSIP number. In addition, on or after the Resale Restriction Termination Date, upon the request of any Holder and upon surrender of its Security for exchange, the Company shall exchange a Physical Security with the Security Private Placement Legend for a Physical Security without the Security Private Placement Legend so long as the Holder covenants to the Company that it will offer, sell, pledge or otherwise transfer such Security in compliance with the Securities Act. The Company shall be entitled to instruct the Trustee in writing to cancel any Global Security as to which such restrictions on transfer shall have expired in accordance with their terms for exchange, and, upon such instruction, the Trustee shall provide evidence of cancellation of such Global Security; and any new Global Security exchanged therefor shall not bear the Security Private Placement Legend specified in this Section 2.17(a) and shall not be assigned a restricted CUSIP number. The Company shall promptly notify the Trustee in writing upon the occurrence of the Resale Restriction Termination Date and promptly after a registration statement, if any, with respect to the Securities or any Common Stock issued upon conversion of the Securities has been declared effective under the Securities Act.

(b) Until the Resale Restriction Termination Date, any stock certificate representing Common Stock issued upon conversion of a Security, if any, shall, if such shares constitute

24

Restricted Securities at their time of issuance, bear the legend (the “ Common Stock Private Placement Legend ”) as set forth in Exhibit B-1B unless (i) such Common Stock has been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, (ii) such Common Stock has been sold pursuant to Rule 144 under the Securities Act or any similar provision then in force, (iii) such Common Stock has been issued upon conversion of a Security that has been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, or pursuant to Rule 144 under the Securities Act or any similar provision then in force or (iv) otherwise agreed by the Company in writing.

(c) Each Global Security shall also bear the legend as set forth in Exhibit B-2 .

provided , however , that if such Fundamental Change Repurchase Date is after a Record Date for the payment of an installment of interest and on or before the related Interest Payment Date, then the full amount of accrued and unpaid interest, if any, to, but excluding, such Interest Payment Date shall be paid on such Interest Payment Date to the Holder of record of such Securities at the Close of Business on such Record Date (without any surrender of such Securities by such Holder), and the Fundamental Change Repurchase Price shall not include any accrued but unpaid interest.

If such Securities are held in book-entry form through the Depository, the delivery of any Securities, Repurchase Notice, Fundamental Change Notice or notice of withdrawal pursuant to the immediately succeeding paragraph shall comply with the Applicable Procedures.

Notwithstanding anything herein to the contrary, any Holder that has delivered the Repurchase Notice contemplated by this Section 3.01(a) to the Company (if it is acting as its own Paying Agent) or to a Paying Agent designated by the Company for such purpose in the Fundamental Change Notice shall have the right to withdraw such Repurchase Notice by delivery, at any time prior to the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date (or, if there shall be a Default in the payment of the Fundamental Change Repurchase Price, at any time during which such Default is continuing), of a written notice of withdrawal to the Company (if acting as its own Paying Agent) or the Paying Agent, which notice shall be delivered in accordance with, and contain the information specified in, Section 3.01(b)(x).

The Company will pay, in money of the United States that at the time of payment is legal tender for payment of public and private debts, all amounts due in cash with respect to the Securities, which amounts shall be paid: (a) in the case of a Global Security, by wire transfer of immediately available funds to the account designated by the Depository or its nominee; and (b) in the case of a Physical Security, by wire transfer of immediately available funds to the account within the United States as specified in writing to the Paying Agent by such Holder or, if such Holder does not specify an account, by mailing a check to the address of such Holder set forth in the register of the Registrar.

The Company will maintain, or cause to be maintained, an office or agency where notices and demands to or upon the Company in respect of the Securities and this Indenture (other than the type contemplated by Section 14.09(c)) may be served, provided that such office or agency may instead be at the principal office of the Company located in the United States (and, notwithstanding the final sentence of this Section 4.02, shall initially be at such office until the Company notifies the Trustee otherwise).

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.

Rule 144A(d)(4) under the Securities Act.

(b) Delivery of such reports, information and documents to the Trustee pursuant to this Section 4.03 is for informational purposes only, and the Trustee’s receipt of such shall not constitute actual or constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on an Officers’ Certificate).

(c) The Trustee shall have no obligation or duty to determine or monitor whether the Company has delivered reports in accordance with this Section 4.03.

Such Additional Interest shall accrue on the Securities at the rate of 0.50% per annum of the principal amount of the Securities outstanding for each day during the period for which the Company’s failure to file has occurred and is continuing or the Securities are not otherwise freely tradable by Holders other than the Company’s Affiliates (or Holders that have been the Company’s Affiliates at any time during the three months immediately preceding) without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Securities. As used in this Section 4.03(d), documents or reports that the Company is required to “file” with the SEC pursuant to Section 13 or 15(d) of the Exchange Act do not include documents or reports that the Company furnishes to the SEC pursuant to Section 13 or 15(d) of the Exchange Act.

(e) If, and for so long as, the Security Private Placement Legend has not been removed, the Securities are assigned a restricted CUSIP number or the Securities are not otherwise freely tradable by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months immediately preceding (without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Securities) as of the 365th day after the Issue Date, the Company shall pay Additional Interest on the Securities at a rate equal to 0.50% per annum of the principal amount of Securities outstanding

31

until the Security Private Placement Legend has been removed, the Securities are assigned an unrestricted CUSIP number and the Securities are freely tradable by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months immediately preceding) without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Securities.

(f) Additional Interest will be payable in arrears on each Interest Payment Date following accrual thereof in the same manner as regular interest on the Securities.

(g) The Additional Interest that is payable in accordance with Section 4.03(d) or Section 4.03(e) shall, subject to the immediately succeeding sentence, be in addition to, and not in lieu of, any Additional Interest that may be payable as a result of the Company’s election pursuant to 6.02(b). However, in no event shall any Additional Interest that may accrue as a result of the Company’s failure to timely file any document or report that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than reports on Form 8-K), as described in Section 4.03(d), together with any interest that may accrue in the event the Company elects to pay Additional Interest in respect of an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.03(a) pursuant to Section 6.02(b), accrue at a rate in excess of 0.50% per annum pursuant to this Indenture, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest.

(h) If the Company is required to pay Additional Interest to Holders, the Company shall provide a direction or order in the form of a written notice to the Trustee (and if the Trustee is not the Paying Agent, to the Paying Agent) of the Company’s obligation to pay such Additional Interest no later than three Business Days prior to the date on which any such Additional Interest is scheduled to be paid. Such notice shall set forth the amount of Additional Interest to be paid by the Company on such payment date and direct the Trustee (or, if the Trustee is not the Paying Agent, to the Paying Agent) to make payment to the extent it receives funds from the Company to do so. The Trustee shall not at any time be under any duty or responsibility to any Holder to determine whether the Additional Interest is payable, or with respect to the nature, extent or calculation of the amount of the Additional Interest owed, or with respect to the method employed in such calculation of the Additional Interest.

Section 4.04. Compliance Certificate. The Company shall deliver to the Trustee, within one hundred and twenty (120) calendar days after the end of each fiscal year of the Company, commencing with the fiscal year ending December 31, 2016, a certificate from the principal executive, financial or accounting officer of the Company stating that such officer has conducted or supervised a review of the activities of the Company and its performance of obligations under this Indenture and the Securities and that, based upon such review, no Default or Event of Default exists hereunder or thereunder or, if a Default or Event of Default then exists, specifying such event, status and the remedial action proposed to be taken by the Company with respect to such Default or Event of Default.

32

Section 4.05. Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture or the Securities; 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, by resort to any such law, 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 has been enacted.

Section 4.06. Notice of Default. Within 30 days of the Company’s becoming aware of the occurrence of any Default or Event of Default, the Company shall give written notice to the Trustee of such Default or Event of Default, and any remedial action proposed to be taken.

ARTICLE 5

SUCCESSORS

Section 5.01. When Company May Merge, Etc. Subject to Section 5.02, the Company shall not consolidate with, or merge with or into, or sell, transfer, lease, convey or otherwise dispose of all or substantially all of the consolidated property or assets of the Company and its Subsidiaries, taken as a whole, to another Person (other than one or more Wholly Owned Subsidiaries of the Company (it being understood that this Article 5 shall not apply to a sale, transfer, lease, conveyance or other disposition of property or assets between or among the Company and its Wholly Owned Subsidiaries)), whether in a single transaction or series of related transactions, unless (i)(x) the Company is the continuing Person or (y) such other Person is a corporation organized and existing under the laws of the United States of America, any state of the United States of America or the District of Columbia, such other Person assumes by supplemental indenture all of the obligations of the Company under the Securities and this Indenture and following such transaction or series of related transactions the Reference Property does not include interests in an entity that is a partnership for U.S. federal income tax purposes and (ii) immediately after giving effect to such transaction or series of transactions, no Default or Event of Default shall have occurred and be continuing under this Indenture.

For purposes of this Section 5.01, the sale, transfer, lease, conveyance or other disposition of all or substantially all of the properties or assets of one or more Subsidiaries of the Company to another Person other than the Company or one or more other Wholly Owned Subsidiaries of the Company, which properties or assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the consolidated properties or assets of the Company and its Subsidiaries, taken as a whole, shall be deemed to be the sale, transfer, lease, conveyance or other disposition of all or substantially all of the consolidated properties or assets of the Company and its Subsidiaries, taken as a whole, to another Person.

The Company shall deliver to the Trustee substantially concurrently with or prior to the consummation of the proposed transaction an Officers’ Certificate and an Opinion of Counsel (which may rely upon such Officers’ Certificate as to the absence of Defaults and Events of Default and other statements of fact) stating that the proposed transaction and, if required, such supplemental indenture (if any) will, upon consummation of the proposed transaction, comply with the applicable provisions of this Indenture.

33

Section 5.02. Successor Substituted. In case of any such consolidation, merger or any sale, transfer, lease, conveyance or other disposition of all or substantially all of the consolidated property or assets of the Company and its Subsidiaries, taken as a whole, and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of and accrued and unpaid interest on all of the Securities, the due and punctual payment of the Fundamental Change Repurchase Price with respect to all Securities repurchased on each Fundamental Change Repurchase Date, the due and punctual payment of the Redemption Price due on a Redemption Date, the due and punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Securities and the due and punctual performance of all of the covenants and conditions of this Indenture and the Securities to be performed by the Company, such successor Person shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such successor Person thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Securities issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such successor Person instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Securities that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication, and any Securities that such successor Person thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Securities so issued shall in all respects have the same legal rank and benefit under this Indenture as the Securities theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Securities had been issued at the date of the execution hereof. In the event of any such consolidation, merger or any sale, transfer, conveyance or other disposition (but not in the case of a lease), upon compliance with this Article 5, the Person named as the “Company” in the first paragraph of this Indenture or any successor that shall thereafter have become such in the manner prescribed in this Article 5, except in the case of a lease, shall be released from its liabilities as obligor and maker of the Securities and its obligations under this Indenture shall terminate.

(g) a final judgment or judgments for the payment of $40,000,000 (or its foreign currency equivalent) or more (excluding any amounts covered by insurance) in the aggregate is rendered against the Company or any Subsidiary of the Company, which judgment is not discharged, paid, bonded, waived or stayed within 30 days after (i) the date on which the right to appeal thereof has expired if no such appeal has commenced, or (ii) the date on which all rights to appeal have been extinguished;

(h) the Company or any Significant Subsidiary, pursuant to, or within the meaning of, any Bankruptcy Law, insolvency law, or other similar law now or hereafter in effect or otherwise, either:

(i) commences a voluntary case,

(ii) consents to the entry of an order for relief against it in an involuntary case,

(iii) consents to the appointment of a Bankruptcy Custodian of it or for all or substantially all of its property, or

(iii) orders the winding up or liquidation of the Company or any Significant Subsidiary,

and, in the case of each of the foregoing clauses (i), (ii) and (iii) of this Section 6.01(i), the order or decree remains unstayed and in effect for at least sixty (60) consecutive days.

A Default under clause (e) above shall not be an Event of Default until (A) the Trustee notifies the Company in writing, or the Holders of at least twenty five percent (25%) in aggregate principal amount of the Securities then outstanding notify the Company and the Trustee in writing, of the Default and (B) the Default is not cured within sixty (60) days after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that the notice is a “Notice of Default.” If the Holders of at least twenty five percent (25%) in aggregate principal amount of the outstanding Securities request the Trustee to give such notice on their behalf, the Trustee shall do so. When a Default is cured, it ceases to exist for all purposes under this Indenture.

Section 6.02. Acceleration . (a) Subject to Section 6.02(b), if applicable, if an Event of Default (excluding an Event of Default specified in Section 6.01(h) or Section 6.01(i)) has occurred and is continuing, either the Trustee, by written notice to the Company, or the Holders of at least twenty five percent (25%) in aggregate principal amount of the Securities then outstanding, by written notice to the Company and the Trustee, may declare 100% of the principal of, and accrued and unpaid interest on, all the Securities to be immediately due and payable in full. Upon such declaration, the principal of, and any accrued and unpaid interest on, all Securities shall be due and payable immediately. If an Event of Default specified in Section 6.01(h) or Section 6.01(i) occurs, 100% of the principal of, and accrued and unpaid interest on, all the Securities shall automatically become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders of a majority in aggregate principal amount of the Securities then outstanding by written notice to the Trustee may rescind or annul an acceleration and its consequences if (i) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction, (ii) all existing Events of Default, except the nonpayment of principal or interest that has become due solely because of the acceleration, have been cured or waived (or are waived concurrently with such rescission or annulment) and (iii) all amounts due to the Trustee under Section 7.06 have been paid. Upon any such rescission or annulment, the Events of Default that were the subject of such acceleration

36

shall cease to exist and deemed to have been cured for every purpose. Notwithstanding anything to the contrary herein, no such rescission and/or annulment shall extend to or shall affect any Default or Event of Default resulting from (i) the nonpayment of the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, any Securities, (ii) a failure to repurchase any Securities when required or (iii) a failure to pay or deliver, as the case may be, the consideration due upon conversion of the Securities.

(b) Notwithstanding the foregoing, for the first 180 days immediately following an Event of Default relating to failure to comply with Section 4.03(a) or for any failure to comply with the requirements of Section 314(a)(1) of the TIA (at any time such section is applicable to the Indenture) (which will be the 61st day after written notice is provided to the Company of the Default pursuant to the last paragraph of Section 6.01, unless such failure is cured or waived prior to such 61st day), the sole remedy for any such Event of Default shall, at the Company’s election, be the accrual of Additional Interest on the Securities at a rate per year equal to (i) 0.25% of the outstanding principal amount of Securities for the first 90 days following the occurrence of such Event of Default and (ii) 0.50% of the outstanding principal amount of Securities for the next 90 days after the first 90 days following the occurrence of such Event of Default, in each case, payable in the same manner and at the same time as the stated interest payable on the Securities. Such Additional Interest shall accrue on all outstanding Securities from, and including, the date on which such Event of Default first occurs to, and including, the 180th day thereafter (or such earlier date on which such Event of Default shall have been cured or waived). On and after the 181st day immediately following an Event of Default relating to a failure to comply with Section 4.03(a), if the Company elected to pay Additional Interest pursuant to this Section 6.02(b) such Additional Interest will cease to accrue and, if such Event of Default has not been cured or waived prior to such 181st day, the payment of the principal of the Securities may be accelerated by the Holders or the Trustee as provided above.

In order to elect to pay Additional Interest as the sole remedy during the first 180 days after the occurrence of any Event of Default relating to the failure to comply with the obligations under Section 4.03(a) or for any failure to comply with the requirements of Section 314(a)(1) of the TIA (at any time such section is applicable to this Indenture, if any), the Company shall notify all Holders and the Trustee and the Paying Agent of such election in writing prior to the Close of Business on the date that is one Business Day following the date on which such Event of Default occurs (which will be the 61st day after written notice is provided to the Company of the Default pursuant to the last paragraph of Section 6.01, unless such failure is cured or waived prior to such 61st day). If the Company fails to give timely notice of such election, the Securities will be immediately subject to acceleration as provided in Section 6.02(a).

In the event the Company does not elect to pay Additional Interest upon such Event of Default in accordance with this Section 6.02(b), the Securities will be subject to acceleration as provided in Section 6.02(a). This Section 6.02(b) does not affect the rights of Holders if any other Event of Default occurs under this Indenture.

37

Additional Interest shall be payable at the same time, in the same manner and to the same Persons as ordinary interest. Any Additional Interest that is payable in accordance with this Section 6.02(b) shall, subject to the immediately succeeding sentence, be in addition to, and not in lieu of, any Additional Interest that is payable pursuant to Section 4.03(d) and Section 4.03(e). However, in no event will the rate of any such Additional Interest payable pursuant to this Section 6.02(b), when taken together with any Additional Interest that may accrue as a result of the Company’s failure to timely file any document or report that it is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than reports on Form 8-K), as described under Section 4.03(d), accrue at a rate in excess of 0.50% per annum, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest.

(c) If the Company is required to pay Additional Interest to Holders, the Company shall provide a direction or order in the form of a written notice to the Trustee (and if the Trustee is not the Paying Agent, to the Paying Agent) of the Company’s obligation to pay such Additional Interest no later than three Business Days prior to the date on which any such Additional Interest is scheduled to be paid. Such notice shall set forth the amount of Additional Interest to be paid by the Company on such payment date and direct the Trustee (or, if the Trustee is not the Paying Agent, to the Paying Agent) to make payment to the extent it receives funds from the Company to do so. The Trustee shall not at any time be under any duty or responsibility to any Holder to determine whether the Additional Interest is payable, or with respect to the nature, extent or calculation of the amount of the Additional Interest owed, or with respect to the method employed in such calculation of the Additional Interest.

Section 6.03. Other Remedies. Notwithstanding any other provision of this Indenture, if an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of amounts due with respect to the Securities or to enforce the performance of any provision of the Securities or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder 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. All remedies are cumulative.

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

In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of any waiver pursuant hereto or any rescission and annulment pursuant hereto or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Holders and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders and the Trustee shall continue as though no such proceeding had been instituted.

(i) all existing Defaults or Events of Default, other than the nonpayment of the principal of and interest on the Securities that have become due solely by the declaration of acceleration, have been cured or waived; and

(ii) the waiver would not conflict with any judgment or decree of a court of competent jurisdiction.

Section 6.05. Control by Majority. The Holders of a majority in aggregate principal amount of the Securities then outstanding shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it with respect to the Securities. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, is unduly prejudicial to the rights of other Holders or would involve the Trustee in personal liability unless the Trustee is offered indemnity satisfactory to it; provided that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction.

Section 6.06. Limitation on Suits. Except with respect to any proceeding instituted in accordance with Section 6.07, a Holder shall not have any right to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver or a trustee, or for any other remedy under this Indenture unless:

(a) such Holder previously shall have given the Trustee written notice of a continuing Event of Default;

(b) the Holders of at least twenty five percent (25%) in aggregate principal amount of the Securities then outstanding shall have made a written request to the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder;

39

(c) such Holder or Holders shall have offered and if requested, provided to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense to or of the Trustee in connection with pursuing such remedy; and

(d) the Trustee shall have failed to comply with the request for sixty (60) days after receipt of such notice, request and offer of indemnity, and during such sixty (60) day period, the Holders of a majority in aggregate principal amount of the Securities then outstanding have not given the Trustee a direction that is inconsistent with the request.

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders). A Holder shall have the right to not enforce any right under this Indenture except in the manner herein.

Section 6.07. Rights of Holders to Receive Payment and to Convert Securities. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of all amounts (including any principal, interest or the Fundamental Change Repurchase Price or the Redemption Price) due with respect to the Securities, on or after the respective due dates as provided herein, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of the Holder.

In addition, notwithstanding any other provision of this Indenture, the right of any Holder to convert a Security in accordance with this Indenture, or to bring suit for the enforcement of such right, shall not be impaired or affected without the consent of the Holder.

Section 6.08. Collection Suit by Trustee. If an Event of Default specified in Section 6.01(a) or Section 6.01(b) has occurred 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 due with respect to the Securities, including any unpaid and accrued interest.

Section 6.09. Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee, any predecessor Trustee and the Holders allowed in any judicial proceedings relative to the Company or its creditors or properties.

The Trustee may 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 judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the 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.

40

Section 6.12. Notice of Defaults . The Trustee shall, within 90 days after the occurrence and continuance of a Default of which a Responsible Officer has received written notice of, mail or transmit to all Holders, as the names and addresses of such Holders appear upon the security register of the Registrar, notice of all Defaults known to a Responsible Officer, unless such Defaults shall have been cured or waived before the giving of such notice; provided that, except in the case of a Default in the payment of the principal of (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable), or accrued and unpaid interest on, any of the Securities or a Default in the payment or delivery of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if and so long as a committee of Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders.

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 7.06.

46

Section 7.08. Successor Trustee by Merger, Etc.

Notwithstanding the foregoing or anything herein to the contrary, without the consent of the Holder of each outstanding Security affected, an amendment, supplement or waiver, including a waiver pursuant to Section 6.04, may not:

(a) change the stated maturity of the principal of, or the payment date of any installment of interest on, any Security;

(b) reduce the principal amount of any Security, or any interest on, any Security or alter or waive the provisions with respect to the redemption of such Security;

(c) change the place or currency of payment of principal of, or any interest on, any Security;

(d) impair the right of any Holder to receive any payment on, or with respect to, or any delivery or payment due upon the conversion of, any Security or impair the right to institute suit for the enforcement of any delivery or payment on, or with respect to, or due upon the conversion of, any Security;

(e) modify, in a manner adverse to Holders, the obligation of the Company pursuant to Section 3.01 to repurchase Securities upon the occurrence of a Fundamental Change;

(f) adversely affect the right of Holders to convert Securities in accordance with Article 10;

(g) reduce the percentage in aggregate principal amount of outstanding Securities whose Holders must consent to a modification to or amendment of any provision of this Indenture or the Securities; or

(h) modify the provisions of Article 9 that require each Holder’s consent or the waiver provisions of Section 6.04 with respect to modification and waiver (including waiver of a Default or an Event of Default), except to increase the percentage required for modification or waiver or to provide for the consent of each affected Holder.

Notwithstanding the foregoing or anything to the contrary, so long as any Atairos Securities are outstanding, without the consent of the Holders of 100% of the aggregate principal amount of the Atairos Securities, an amendment, supplement or waiver, including a waiver pursuant to Section 6.04, may not modify any provision contained in this Indenture specifically and uniquely applicable to the Atairos Securities in a manner adverse to the Holders of, or the holders of a beneficial interest in, the Atairos Securities.

50

Promptly after an amendment, supplement or waiver under Section 9.01 or this Section 9.02 becomes effective, the Company shall send, or cause to be sent, to Holders a notice briefly describing such amendment, supplement or waiver. Any failure of the Company to send such notice shall not in any way impair or affect the validity of such amendment, supplement or waiver.

It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof.

Section 9.03. Revocation and Effect of Consents . Until an amendment, supplement or waiver becomes effective (or until such earlier date as specified by the Company in connection with the solicitation of such consent), a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to its Security or portion of a Security if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective (or such earlier date specified by the Company in connection with the solicitation of such consent).

After an amendment, supplement or waiver becomes effective with respect to the Securities, it shall bind every Holder unless such amendment, supplement or waiver makes a change that requires, pursuant to Section 9.02, the consent of each Holder affected. In that case, the amendment, supplement or waiver shall bind each Holder of a Security who has consented to it and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security. Any amendment to this Indenture or the Securities shall be set forth in a supplemental indenture to this Indenture that complies with the TIA as then in effect, if the TIA is applicable to this Indenture.

Nothing in this Section 9.03 shall impair the Company’s rights pursuant to Section 9.01 to amend this Indenture or the Securities without the consent of any Holder in the manner set forth in, and permitted by, such Section 9.01.

Section 9.04. Notation on or Exchange of Securities . If an amendment, supplement or waiver changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security as directed and prepared by the Company about the changed terms and return it to the Holder. Alternatively, if the Company so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms.

Section 9.05. Trustee Protected. The Trustee shall sign any amendment, supplemental indenture or waiver authorized pursuant to this Article 9; provided , however , that the Trustee need not sign any amendment, supplement or waiver authorized pursuant to this Article 9 that

51

adversely affects the Trustee’s rights, duties, liabilities or immunities. The Trustee shall be entitled to receive and conclusively rely upon, in addition to the documents set forth in Section 14.03, an Opinion of Counsel as to legal matters and an Officers’ Certificate as to factual matters each stating that any supplemental indenture, amendment or waiver is permitted or authorized pursuant to this Indenture and constitutes the legal, valid and binding obligation of the Company enforceable in accordance with its terms (subject to customary exceptions).

Section 9.06. Effect of Supplemental Indentures. Upon the due execution and delivery of any supplemental indenture in accordance with this Article 9, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes, and, except as set forth in Section 9.02 and Section 9.03, every Holder of Securities shall be bound thereby.

ARTICLE 10

CONVERSION

Section 10.01. Conversion Privilege. (a) Subject to the limitations of Section 10.02, Section 10.11 and the settlement provisions of Section 10.14(c), and upon compliance with the provisions of this Article 10, each Holder of a Security shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or a multiple thereof) of such Security at any time prior to the Close of Business on the Scheduled Trading Day immediately preceding the Maturity Date, in each case, at the then applicable Conversion Rate per $1,000 principal amount of Securities (subject to the settlement provisions of Section 10.02, the “ Conversion Obligation ”).

(b) To convert its Security, a Holder of a Physical Security must (i) complete and manually sign the Conversion Notice, with appropriate notarization or signature guarantee, or facsimile of the Conversion Notice and deliver the completed Conversion Notice or facsimile thereof to the Conversion Agent, (ii) surrender the Security to the Conversion Agent, (iii) furnish appropriate endorsements and transfer documents if required by the Registrar or Conversion Agent, (iv) pay all transfer or similar taxes if required pursuant to Section 10.04 and (v) pay funds equal to interest payable on the next Interest Payment Date if so required by Section 10.02(d). If a Holder holds a beneficial interest in a Global Security, to convert such Security, the Holder must comply with clauses (iv) and (v) above and the Depository’s procedures for converting a beneficial interest in a Global Security.

(c) A Holder may convert a portion of the principal amount of a Security if such portion is $1,000 principal amount or an integral multiple of $1,000 principal amount in excess thereof. Provisions of this Indenture that apply to conversion of all of a Security also apply to conversion of a portion of such Security.

Section 10.02. Conversion Procedure and Payment Upon Conversion.

(a) Subject to this Section 10.02 and Section 10.11 and the settlement provisions of Section 10.14(c), upon conversion of any Security, the Company shall pay or deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal amount of Securities

52

being converted, cash (“ Cash Settlement ”), Common Stock, together with cash, if applicable, in lieu of delivering any fractional shares of Common Stock in accordance with Section 10.03 (“ Physical Settlement ”) or a combination of cash and Common Stock, together with cash, if applicable, in lieu of delivering any fractional shares of Common Stock in accordance with Section 10.03 (“ Combination Settlemen t”), at its election, as set forth in this Section 10.02.

(i) All conversions for which the relevant Conversion Date occurs on or after the 22nd Scheduled Trading Day immediately preceding the Maturity Date, and all conversions for which the relevant Conversion Date occurs after the Company’s issuance of a notice of redemption with respect to the Securities and prior to the related Redemption Date, shall be settled using the same Settlement Method.

(ii) The Company shall use the same Settlement Method for all conversions of Securities occurring on the same Conversion Date (except for any conversions described in the immediately preceding clause (i)), but the Company shall not have any obligation to use the same Settlement Method with respect to conversions that occur on different Conversion Dates.

(iii) If, in respect of any Conversion Date (or for all conversions in any period), the Company elects to deliver a notice (the “ Settlement Notice ”) of the relevant Settlement Method in respect of such Conversion Date (or such period, as the case may be), the Company, through the Trustee, shall deliver such Settlement Notice to converting Holders no later than the Close of Business on the Trading Day immediately following the relevant Conversion Date to which such Settlement Notice applies (or, in the case of any conversions for which the relevant Conversion Date occurs (x) after the date of issuance of a notice of redemption and prior to the related Redemption Date, in such notice of redemption or (y) on or after the 22nd Scheduled Trading Day immediately preceding the Maturity Date, no later than the 22nd Scheduled Trading Day immediately preceding the Maturity Date). If the Company does not elect a Settlement Method prior to the deadline set forth in the immediately preceding sentence for a Conversion Date, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement with respect to conversions on such Conversion Date and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation on such Conversion Date, and the Specified Dollar Amount per $1,000 principal amount of Securities shall be equal to $1,000. Such Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount per $1,000 principal amount of Securities. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount per $1,000 principal amount of Securities in such Settlement Notice, the Specified Dollar Amount per $1,000 principal amount of Securities shall be deemed to be $1,000. Notwithstanding the foregoing, any conversion of Atairos Securities shall be subject to Section 10.02(a)(v).

53

(iv) The cash, Common Stock or combination of cash and Common Stock in respect of any conversion of Securities (the “ Settlement Amount ”) shall be computed as follows:

(A) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall deliver to the converting Holder in respect of each $1,000 principal amount of Securities being converted a number of shares of Common Stock equal to the Conversion Rate in effect on the Conversion Date ( provided that the Company shall deliver cash in lieu of any fractional shares as described in Section 10.03);

(B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company shall pay to the converting Holder in respect of each $1,000 principal amount of Securities being converted cash in an amount equal to the sum of the Daily Conversion Values for each Trading Day during the related Observation Period; and

(C) if the Company elects (or is deemed to have elected pursuant to Section 10.02(a)(iii)) to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver to the converting Holder, as the case may be, in respect of each $1,000 principal amount of Securities being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each Trading Day during the related Observation Period.

(v) Notwithstanding anything herein to the contrary, the Company hereby initially elects to satisfy its Conversion Obligation with respect to any conversion of Atairos Securities by Combination Settlement with a Specified Dollar Amount of $1,000 per $1,000 principal amount of Securities. The Company may change its Settlement Method election (and, in the case of Combination Settlement, the Specified Dollar Amount) with respect to any conversion of Atairos Securities by delivering a notice that specifies the newly elected Settlement Method and, in the case of Combination Settlement, the applicable Specified Dollar Amount (the “ Atairos Settlement Notice ”) to the Holders of the Atairos Securities, and such newly elected Settlement Method (and, in the case of Combination Settlement, the Specified Dollar Amount) shall be effective no earlier than ten (10) Trading Days after the date on which such Atairos Settlement Notice was received by the Holder. In the event any Holder(s) of Atairos Securities exercises its right to convert all or any portion of such Atairos Securities, (A) the relevant Observation Period for purposes of determining the Daily Settlement Amount, in the case of Combination Settlement, and Daily Conversion Values, in the case of Cash Settlement, with respect to such Atairos Securities shall be the 20 consecutive Trading Day period beginning on, and including, the 20th Trading Day immediately preceding the applicable Conversion Date and ending on the Trading Day immediately preceding such Conversion Date and (B) the Company shall promptly (x) determine the Daily Settlement Amount or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering any fractional shares of Common Stock and (y) notify the Trustee, the Conversion Agent (if other than the Trustee) and such Holder

54

of Atairos Securities being so converted of the Daily Settlement Amount or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering any fractional shares of Common Stock.

(vi) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering any fractional shares of Common Stock, and in any event within one (1) Business Day following the last day of the Observation Period, the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination.

(b) Each conversion shall be deemed to have been effected as to any Securities surrendered for conversion at the Close of Business on the applicable Conversion Date; provided , however , that the Person in whose name any shares of the Common Stock shall be issuable upon such conversion shall become the holder of record of such shares as of the Close of Business on such Conversion Date (in the case of Physical Settlement or any conversion of Atairos Securities) or the last Trading Day of the relevant Observation Period (in the case of Combination Settlement of Securities other than Atairos Securities). Prior to such time, a Holder receiving Common Stock upon conversion shall not be entitled to any rights relating to such Common Stock, including, among other things, the right to vote and receive dividends and notices of shareholder meetings. The Company will determine the Conversion Date and the last Trading Day of the relevant Observation Period, as applicable, in accordance with the requirements set forth herein and notify the Trustee of the same.

(c) In the case of any conversion of Securities other than the Atairos Securities, the Company shall pay or deliver, as the case may be, the consideration due in respect of the Conversion Obligation on the later of (i) the third Business Day immediately following the relevant Conversion Date (in the case of Physical Settlement) and (ii) the third Business Day immediately following the last Trading Day of the relevant Observation Period (in the case of Combination Settlement or Cash Settlement). In the case of any conversion of Atairos Securities, (i) to the extent all or a portion of the Conversion Obligation is paid in cash, such cash shall not be due until the earlier of (A) the 30th Business Day immediately following the relevant Conversion Date and (B) the Maturity Date, and (ii) to the extent all or a portion of the Conversion Obligation is to be paid in shares of Common Stock, such shares shall be delivered on the day specified in a written notice from the beneficial owner(s) of the Atairos Securities being converted that is delivered to the Company on or prior to the second Business Day immediately following the relevant Conversion Date, which delivery date (in respect of such shares of Common Stock) shall be no earlier than the third Business Day immediately following the relevant Conversion Date and be no later than the seventh Business Day immediately following the relevant Conversion Date (it being understood that if no such notice is delivered to the Company, then the Company shall deliver such shares on the third Business

55

Day immediately following the relevant Conversion Date). Such written notice shall include a certification therein that the beneficial owners delivering such written notice are holders that hold beneficial interests in the Atairos Securities subject to conversion. If any shares of Common Stock are due to converting Holders, the Company shall issue or cause to be issued, and deliver or cause to be delivered to such Holder, or such Holder’s nominee(s) or transferee(s), certificates or a book-entry transfer through the Depository for the full number of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation.

(d) Except to the extent otherwise provided in this Section 10.02(d), no payment or adjustment will be made for accrued interest on a converted Security, and accrued interest, if any, will be deemed to be paid by the consideration paid to the Holder upon conversion. Such accrued interest, if any, shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. The Company’s settlement of the full Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Security and accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date. Upon a conversion of Securities into a combination of cash and Common Stock, accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such conversion. If any Holder surrenders a Security for conversion after the Close of Business on the Record Date for the payment of an installment of interest but prior to the Open of Business on the next Interest Payment Date, then, notwithstanding such conversion, the full amount of interest payable with respect to such Security on such Interest Payment Date shall be paid on such Interest Payment Date to the Holder of record of such Security at the Close of Business on such Record Date; provided , however , that such Security, when surrendered for conversion, must be accompanied by payment in cash to the Conversion Agent on behalf of the Company of an amount equal to the full amount of interest payable on such Interest Payment Date on the Security so converted; provided further , however , that such payment to the Conversion Agent described in the immediately preceding proviso in respect of a Security surrendered for conversion shall not be required with respect to a Security that (i) is surrendered for conversion after the Close of Business on the Record Date immediately preceding the Maturity Date, (ii) is surrendered for conversion after the Close of Business on a Record Date for the payment of an installment of interest and on or prior to the Open of Business on the related Interest Payment Date, where, pursuant to Section 3.01, the Company has specified, with respect to a Fundamental Change, a Fundamental Change Repurchase Date that is after such Record Date but on or prior to such Interest Payment Date or (iii) is surrendered for conversion after the Close of Business on a Record Date for the payment of an installment of interest and on or prior to the Open of Business on the related Interest Payment Date, where, pursuant to Section 13.01, the Company has specified a Redemption Date that is after such Record Date but on or prior to such Interest Payment Date.

(e) If a Holder converts more than one Security at the same time, the Conversion Obligation with respect to such Securities shall be based on the total principal amount of all Securities so converted.

56

(f) Upon surrender of a Security that is converted in part, the Trustee shall authenticate for the Holder a new Security equal in principal amount to the unconverted portion of the Security surrendered.

Section 10.03. Cash in Lieu of Fractional Shares . The Company shall not issue fractional shares of Common Stock upon the conversion of a Security. Instead, the Company shall pay to converting Holders cash in lieu of fractional shares based on the Daily VWAP on the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP on the last Trading Day of the relevant Observation Period (in the case of Combination Settlement). If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares that shall be issuable upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the relevant Observation Period (in the case of Combination Settlement) or the aggregate principal amount of the Securities, or specified portions thereof to the extent permitted hereby (in the case of Physical Settlement) so surrendered, and any fractional shares remaining after such computation shall be paid in cash.

Section 10.04. Taxes on Conversion . If a Holder converts its Security, the Company shall pay any documentary, stamp or similar issue or transfer tax or duty due on the issue, if any, of Common Stock upon the conversion. However, the Holder shall pay such tax which is due because the Holder requests the shares of Common Stock to be issued in a name other than the Holder’s name. The Company may refuse to deliver the certificate(s) representing the Common Stock being issued or delivered to the Holder or in a name other than such Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax or duty which will be due because shares of Common Stock are to be issued or delivered in a name other than such Holder’s name.

Section 10.05. Company to Provide Common Stock . The Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued 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 for the conversion of all outstanding Securities into shares of Common Stock at any time (assuming, for such purposes, that (i) Physical Settlement will apply to all conversions of Securities, (ii) at the time of computation of such number of shares, all such Securities would be converted by a single Holder and (iii) the maximum Conversion Rate permitted by Section 10.14 is applicable to such conversion). The Company shall, from time to time and in accordance with Delaware law, cause the authorized number of shares of Common Stock to be increased if the aggregate of the number of authorized shares of Common Stock remaining unissued shall not be sufficient for the conversion of all outstanding (and issuable as set forth above) Securities into shares of Common Stock at any time.

All Common Stock issued upon conversion of the Securities shall be validly issued, fully paid and non-assessable and shall be free of preemptive or similar rights and free of any lien or adverse claim that arises from the action or inaction of the Company.

The Company shall comply with all securities laws regulating the offer and delivery of any Common Stock upon conversion of Securities and shall list such shares on each national securities exchange or automated quotation system on which the Common Stock is listed on the applicable Conversion Date.

57

Section 10.06. Adjustment of Conversion Rate . The Conversion Rate shall be subject to adjustment from time to time, without duplication, upon the occurrence of any of the following events on or after the date of this Indenture:

(a) In case the Company shall pay or make a dividend or other distribution on its Common Stock consisting exclusively of Common Stock, the Conversion Rate shall be increased by multiplying such Conversion Rate by a fraction of which the denominator shall be the number of shares of Common Stock outstanding immediately prior to the Open of Business on the Ex Date for such dividend or distribution, and the numerator shall be the number of shares of Common Stock outstanding immediately after giving effect to such dividend or distribution, based on the following formula:

In case the Company shall effect a share split or share combination of the Common Stock, the Conversion Rate shall be proportionally increased, in the case of a share split, and proportionally reduced, in the case of a share combination, as expressed in the following formula:

58

Any adjustment made under this Section 10.06(a) shall become effective immediately after the Open of Business on the Ex Date for such dividend or distribution, or immediately after the Open of Business on the effective date for such share split or share combination, as the case may be. If any dividend or distribution of the type described in this Section 10.06(a) is declared but not so paid or made, then the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(b) If the Company distributes to all or substantially all holders of the Common Stock any rights, options or warrants entitling them, for a period expiring not more than forty-five (45) days immediately following the date of such distribution, to purchase or subscribe for Common Stock at a price per share less than the average of the Closing Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement for such distribution, the Conversion Rate shall be increased based on the following formula:

59

Any increase made under this Section 10.06(b) shall be made successively whenever any such rights, options or warrants are distributed and shall become effective immediately after the Open of Business on the Ex Date for such distribution. To the extent that Common Stock is not delivered after expiration of such rights, options or warrants, the Conversion Rate shall be readjusted, effective as of the date of such expiration, to the Conversion Rate that would then be in effect had the increase with respect to the distribution of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so distributed, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make such distribution, to the Conversion Rate that would then be in effect if such Ex Date for such distribution had not occurred.

In determining whether any rights, options or warrants entitle the holders to subscribe for or purchase Common Stock at less than such average of the Closing Sale Prices for the ten (10) consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement for such distribution, and in determining the aggregate offering price of such Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. Except in the case of a readjustment of the Conversion Rate pursuant to the immediately preceding paragraph, the Conversion Rate shall not be decreased pursuant to this Section 10.06(b).

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness or other of its assets, securities or property or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of Common Stock, but excluding (i) dividends or distributions as to which an adjustment was effected pursuant to Section 10.06(a) or Section 10.06(b), (ii) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section 10.06(d), (iii) distributions of Reference Property in a transaction described in Section 10.11, (iv) rights issued pursuant to a rights plan of the Company (i.e., a poison pill), except to the extent provided by Section 10.13, and (v) Spin-Offs to which the provisions set forth in the latter portion of this Section 10.06(c) shall apply (any of such shares of Capital Stock, indebtedness or other assets, securities or property or rights, options or warrants to acquire its Capital Stock or other securities, the “ Distributed Property ”), then, in each such case the Conversion Rate shall be increased based on the following formula:

where,

60

If the Board of Directors determines “FMV” for purposes of this Section 10.06(c) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the Closing Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period ending on the Trading Day immediately preceding the Ex Date for such distribution.

Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than the “SP ₀ ” (as defined above), in lieu of the foregoing increase, provision shall be made for each Holder of a Security to receive, for each $1,000 principal amount of Securities it holds, at the same time and upon the same terms as the holders of the Common Stock, the amount and kind of Distributed Property that such Holder would have received if such Holder had owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex Date for such distribution.

Any increase made under the portion of this Section 10.06(c) above shall become effective immediately after the Open of Business on the Ex Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make such distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

With respect to an adjustment pursuant to this Section 10.06(c) where there has been a payment of a dividend or other distribution on the Common Stock of Capital Stock of any class or series, or similar equity interests, of or relating to a Subsidiary or other business unit of the Company, where such Capital Stock or similar equity interest is listed or quoted (or will be listed or quoted upon consummation of the transaction) on a U.S. national securities exchange (a “ Spin-Off ”), the Conversion Rate shall be increased based on the following formula:

where,

61

The increase to the Conversion Rate under the preceding paragraph shall be determined on the last Trading Day of the Valuation Period, but will be given effect immediately after the Open of Business on the Ex Date for such Spin-Off. Notwithstanding the foregoing, (x) in respect of any conversion during the Valuation Period for which Physical Settlement is applicable, references in the portion of this Section 10.06(c) related to Spin-Offs with respect to 10 Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between the Ex Date of such Spin-Off and the Conversion Date in determining the Conversion Rate and (y) in respect of any conversion during the Valuation Period for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the Valuation Period, references in the portion of this Section 10.06(c) related to Spin-Offs with respect to 10 Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between the Ex Date of such Spin-Off and such Trading Day in determining the Conversion Rate as of such Trading Day. If the period from and including the Ex Date for the Spin-Off to and including the last Trading Day of the Observation Period in respect of any conversion of Securities is less than 10 Trading Days, references in the portion of this Section 10.06(c) related to Spin-Offs with respect to 10 Trading Days shall be deemed to be replaced, solely in respect of that conversion of Securities, with such lesser number of Trading Days as have elapsed from, and including, the Ex Date for the Spin-Off to, and including, the last Trading Day of such Observation Period.

Subject in all respects to Section 10.13, rights, options or warrants distributed by the Company to all holders of its Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“ Trigger Event ”): (i) are deemed to be transferred with such Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 10.06(c) (and no adjustment to the Conversion Rate under this Section 10.06(c), will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 10.06(c), as the case may be. If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the

62

date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex Date with respect to new rights, options or warrants with such rights (and a termination or expiration of the existing rights, options or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 10.06(c), as the case may be, was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued.

For purposes of Section 10.06(a), Section 10.06(b) and this Section 10.06(c), if any dividend or distribution to which this Section 10.06(c) is applicable also includes one or both of:

(A) a dividend or distribution of Common Stock to which Section 10.06(a) is applicable (the “ Clause A Distribution ”); or

(B) a dividend or distribution of rights, options or warrants to which Section 10.06(b) is applicable (the “ Clause B Distribution ”),

then (1) such dividend or distribution, other than the Clause A Distribution and Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 10.06(c) is applicable (the “ Clause C Distribution ”) and any Conversion Rate adjustment required by this Section 10.06(c) with respect to such Clause C Distribution shall then be made and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 10.06(a) and Section 10.06(b) with respect thereto shall then be made, except that, if determined by the Board of Directors, the Ex Date of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex Date of the Clause C Distribution and any Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the Open of Business on the Ex Date for such dividend or distribution” or “outstanding immediately after the Open of Business on the effective date of such share split or share combination,” as the case may be within the meaning of Section 10.06(a) or “outstanding immediately prior to the Open of Business on the Ex Date for such distribution” within the meaning of Section 10.06(b).

63

Except in the case of a readjustment of the Conversion Rate pursuant to the last sentence of either the fourth or seventh paragraph of this Section 10.06(c), the Conversion Rate shall not be decreased pursuant to this Section 10.06(c).

(d) If any cash dividend or distribution is made to all or substantially all holders of the Common Stock, the Conversion Rate shall be increased based on the following formula:

Any adjustment made under this Section 10.06(d) shall become effective immediately after the Open of Business on the Ex Date for such dividend or distribution.

Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP ₀ ” (as defined above), in lieu of the foregoing increase, provision shall be made for each Holder of a Security to receive, for each $1,000 principal amount of Securities it holds, at the same time and upon the same terms as holders of the Common Stock, the amount of cash such Holder would have received as if such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the Ex Date for such cash dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

Except in the case of a readjustment of the Conversion Rate pursuant to the last sentence of the immediately preceding paragraph, the Conversion Rate shall not be decreased pursuant to this Section 10.06(d).

64

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for the Common Stock, if the cash and value of any other consideration included in the payment per share of Common Stock exceeds the average of the Closing Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall be increased based on the following formula:

The increase to the Conversion Rate under this Section 10.06(e) shall occur at the Close of Business on the tenth (10th) Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that, for purposes of determining the Conversion Rate, (x) in respect of any conversion for which Physical Settlement is applicable during the ten (10) Trading Days immediately following, but excluding, the date that any such tender or exchange offer expires, references in this Section 10.06(e) to ten (10) consecutive Trading Days shall be deemed to be replaced with such lesser number of consecutive Trading Days as have elapsed between the date such tender or exchange offer

65

expires and the relevant Conversion Date and (y) in respect of any conversion for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the ten (10) Trading Days immediately following, but excluding, the date that any such tender or exchange offer expires, references in this Section 10.06(e) to ten (10) consecutive Trading Days shall be deemed to be replaced with such lesser number of consecutive Trading Days as have elapsed between the date of such tender or exchange offer and such Trading Day in determining the Conversion Rate as of such Trading Day. If the Company or one of its Subsidiaries is obligated to purchase the Common Stock pursuant to any such tender or exchange offer but the Company or such Subsidiary is permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the Conversion Rate shall be immediately decreased to the Conversion Rate that would be in effect if such tender or exchange offer had not been made.

Except in the case of a readjustment of the Conversion Rate pursuant to the last sentence of the immediately preceding paragraph, the Conversion Rate shall not be decreased pursuant to this Section 10.06(e).

(f) In addition to the foregoing adjustments in subsections (a), (b), (c), (d) and (e) above, and to the extent permitted by applicable law and the rules of the Relevant Stock Exchange, the Company may, from time to time and to the extent permitted by law, increase the Conversion Rate by any amount for a period of at least twenty (20) Trading Days or any longer period as may be permitted or required by law, if the Board of Directors has made a determination, which determination shall be conclusive, that such increase would be in the best interests of the Company. Such Conversion Rate increase shall be irrevocable during such period. The Company shall give notice to the Trustee and cause notice of such increase, which notice will include the amount of the increase and the period during which the increase shall be in effect, to be sent to each Holder of Securities in accordance with Section 14.01, at least fifteen (15) days prior to the date on which such increase commences.

(g) All calculations under this Article 10 shall be made to the nearest cent or to the nearest 1/10,000th of a share, as the case may be. Adjustments to the Conversion Rate will be calculated to the nearest 1/10,000 ^th of a share.

(h) Notwithstanding this Section 10.06 or any other provision of this Indenture or the Securities, if a Conversion Rate adjustment becomes effective on any Ex Date, and a Holder that has converted its Securities on or after such Ex Date and on or prior to the related record date would be treated as the record holder of the Common Stock as of the related Conversion Date as described under Section 10.02(b) based on an adjusted Conversion Rate for such Ex Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 10.06, the Conversion Rate adjustment relating to such Ex Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment.

(i) Notwithstanding this Section 10.06 or any other provision of this Indenture or the Securities, if a Holder converts a Security, Combination Settlement is applicable to such

66

Security and the Daily Settlement Amount for any Trading Day during the Observation Period applicable to such Security (x) is calculated based on a Conversion Rate adjusted on account of any event described in clauses (a), (b), (c), (d) and (e) of this Section 10.06 and (y) includes any shares of Common Stock that entitle their holder to participate in such event, then, notwithstanding the Conversion Rate adjustment provisions in this Section 10.06, the Conversion Rate adjustment relating to such event will not be made for such converting Holder for such Trading Day. Instead, such Holder will be treated as if such Holder were the record owner of the Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment.

(j) For purposes of this Section 10.06, “ effective date ” means the first date on which the Common Stock trade on the Relevant Stock Exchange, regular way, reflecting the relevant share split or share combination, as applicable.

(k) For purposes of this Section 10.06, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company shall not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company.

Section 10.07. No Adjustment . The Conversion Rate shall not be adjusted for any transaction or event other than for any transaction or event described in this Article 10. Without limiting the foregoing, the Conversion Rate shall not be adjusted:

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

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

(iii) upon the issuance of any Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (ii) above and outstanding as of the date the Securities were first issued;

(iv) for accrued and unpaid interest, if any;

(v) repurchases of Common Stock that are not tender offers or exchange offers pursuant to Section 10.06(e), including structured or derivative transactions such as accelerated share repurchase transactions or similar forward derivatives;

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

67

(vii) for the issuance of Common Stock or any securities convertible into or exchangeable for Common Stock or the right to purchase Common Stock or such convertible or exchangeable securities, except as described in Section 10.06.

No adjustment in the Conversion Rate of less than one percent (1%) of the Conversion Rate as last adjusted (or, if never adjusted, the initial Conversion Rate) shall be made pursuant to Section 10.06(a) through Section 10.06(e); provided , however , that (i) the Company shall carry forward any adjustments that are not made as a result of the foregoing and make such carried forward adjustments with respect to the Conversion Rate when the cumulative effect of all adjustments not yet made will result in a change of one percent (1%) or more of the Conversion Rate as last adjusted (or, if never adjusted, the initial Conversion Rate) and (ii) notwithstanding the foregoing, all such deferred adjustments that have not yet been made shall be made (including any adjustments that are less than one percent (1%) of the Conversion Rate as last adjusted (or, if never adjusted, the initial Conversion Rate)) (1) on the effective date of any Fundamental Change or Make-Whole Fundamental Change and (2) on (A) the Conversion Date (in the case of Physical Settlement) and (B) on each Trading Day of any Observation Period (in the case of Cash Settlement or Combination Settlement).

No adjustment to the Conversion Rate need be made pursuant to Section 10.06 for a transaction (other than for share splits or share combinations pursuant to Section 10.06(a) or tender offers or exchange offers pursuant to Section 10.06(e)) if the Company makes provision for each Holder to participate in the transaction, at the same time and upon the same terms as holders of Common Stock participate in such transaction, without conversion, as if such Holder held a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex Date or effective date, as applicable, of the transaction (without giving effect to any adjustment pursuant to Section 10.06 on account of such transaction), multiplied by the principal amount (expressed in thousands) of Securities held by such Holder.

Section 10.08. Other Adjustments . Whenever any provision of this Indenture requires the computation of an average of the Closing Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a period of multiple Trading Days (including an Observation Period and the period for determining the Applicable Price for purposes of a Make-Whole Fundamental Change), the Board of Directors, in its good faith determination, shall appropriately adjust such average to account for any event requiring, pursuant hereto, an adjustment to the Conversion Rate where the effective date, Ex Date or expiration date of such event occurs at any time on or after the first Trading Day of such period and on or prior to the last Trading Day of such period.

Section 10.09. Adjustments for Tax Purposes . Except as prohibited by law, the Company may (but is not obligated to) make such increases in the Conversion Rate, in addition to those required by Section 10.06 hereof, as it considers to be advisable to avoid or diminish any income tax to any holders of Common Stock (or rights to purchase Common Stock) resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes or for any other reason.

68

Section 10.10. Notice of Adjustment and Certain Events . (a) Whenever the Conversion Rate is adjusted, the Company shall promptly file with the Trustee an Officers’ Certificate describing in reasonable detail the adjustment and the method of calculation used and the Company shall promptly send to the Holders in accordance with Section 14.01 a notice of the adjustment setting forth the adjusted Conversion Rate and the calculation thereof. The certificate and notice shall be conclusive evidence of the correctness of such adjustment. In the absence of an Officers’ Certificate being filed with the Trustee (and the Conversion Agent if not the Trustee), the Trustee may assume without inquiry that the Conversion Rate has not been adjusted and that the last Conversion Rate of which it has knowledge remains in effect.

(b) In case of any:

(i) action by the Company or one of its Subsidiaries that would require an adjustment to the Conversion Rate in accordance with Section 10.06 or Section 10.13;

(ii) Merger Event; or

(iii) voluntary or involuntary dissolution, liquidation or winding-up of the Company;

then the Company shall at least ten days prior to the anticipated effective date of such transaction or event cause written notice thereof to be sent to the Trustee and the Holders in accordance with Section 14.01 Such notice shall also specify, as applicable, the date or expected date on which the holders of Common Stock shall be entitled to a distribution and the date or expected date on which the holders of Common Stock shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up, as the case may be. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such action by the Company or one of its Subsidiaries, Merger Event, dissolution, liquidation or winding-up.

Section 10.11. Effect of Reclassifications, Consolidations, Mergers, Binding Share Exchanges or Sales on Conversion Privilege . If on or after the date of this Indenture the Company:

(a) reclassifies the Common Stock (other than a change as a result of a subdivision or combination of Common Stock to which Section 10.06(a) applies);

(b) is party to a consolidation, merger or binding share exchange; or

(c) sells, transfers, leases, conveys or otherwise disposes of all or substantially all of the consolidated property or assets of the Company and its Subsidiaries, taken as a whole,

in each case, pursuant to which the Common Stock would be converted into or exchanged for, or would constitute solely the right to receive, cash, securities or other property or assets (any such event, a “ Merger Event ”), each $1,000 principal amount of converted Securities will, from and after the effective time of such Merger Event, be convertible into the same kind, type and proportions of consideration that a holder of a number of shares of Common Stock equal to the

69

Conversion Rate in effect immediately prior to such Merger Event would have received in such Merger Event (“ Reference Property ” with each “ unit of Reference Property ” meaning the kind and amount of Reference Property that a holder of one share of Common Stock is entitled to receive) and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture permitted under Section 9.01(a) providing for such change in the right to convert the Securities; provided , however , that at and after the effective time of the Merger Event (A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Securities in accordance with Section 10.02 and (B) (I) any amount payable in cash upon conversion of the Securities in accordance with Section 10.02 shall continue to be payable in cash, (II) any Common Stock that the Company would have been required to deliver upon conversion of the Securities in accordance with Section 10.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have received in such Merger Event and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property.

If the Merger Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration determined based in whole or in part upon any form of stockholder election, then (i) the Reference Property into which the Securities will be convertible shall be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election (or, if no holders of Common Stock affirmatively make such an election, the types and amounts of consideration actually received by the holders of Common Stock) and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. The Company shall notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as reasonably practicable after such determination is made. If the holders of Common Stock receive only cash in such Merger Event, then for all conversions that occur after the effective date of such Merger Event (A) the consideration due upon conversion of each $1,000 principal amount of Securities shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased pursuant to Section 10.14), multiplied by the price paid per share of Common Stock in such Merger Event and (B) the Company shall satisfy its Conversion Obligation by paying cash to converting Holders on the third Business Day immediately following the relevant Conversion Date.

The supplemental indenture referred to in the first sentence of this Section 10.11 shall provide for adjustments to the Conversion Rate that shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Rate provided for in this Article 10 and for the delivery of cash by the Company in lieu of fractional securities or property that would otherwise be deliverable to holders upon Conversion as part of the Reference Property, with such amount of cash determined by the Board of Directors in a manner as nearly equivalent as may be practicable to that used by the Company to determine the Closing Sale Price of the Common Stock. The provisions of this Section 10.11 shall similarly apply to successive consolidations, mergers, binding share exchanges, sales, transfers, leases, conveyances or dispositions.

70

The Company shall not consummate any Merger Event unless its terms are consistent with this Section 10.11.

None of the foregoing provisions shall affect the right of a Holder to convert its Securities into Common Stock (and cash in lieu of any fractional share) as set forth in Section 10.01 and Section 10.02 prior to the effective date of such Merger Event.

In the event the Company shall execute a supplemental indenture in accordance with this Section 10.11, the Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of Reference Property receivable by Holders of the Securities upon the conversion of their Securities after any such Merger Event and any adjustment to be made with respect thereto.

Section 10.12. Trustee’s Disclaimer . The Trustee and the Conversion Agent shall have no duty to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require that any adjustment under this Article 10 should be made, how it should be made or what such adjustment should be, but may accept as conclusive evidence of the correctness of any such adjustment, and shall be protected in relying upon, the Officers’ Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 10.10 hereof. Neither the Trustee nor the Conversion Agent makes any representation as to the validity or value of any securities or assets issued upon conversion of Securities, and neither the Trustee nor the Conversion Agent shall be responsible for the failure by the Company to comply with any provisions of this Article 10 or to monitor any Person’s compliance with this Article 10.

The Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 10.11, but may accept as conclusive evidence of the correctness thereof, and shall be protected in relying upon, the Officers’ Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 10.11 hereof.

Section 10.13. Rights Distributions Pursuant to Shareholders’ Rights Plans. To the extent that on or after the date of this Indenture the Company adopts a rights plan (i.e., a poison pill) and such plan is in effect upon conversion of any Security or a portion thereof, the Company shall make provision such that each Holder thereof shall receive, in addition to, and concurrently with the delivery of, the Common Stock due upon conversion (if any), the rights described in such plan, unless the rights have separated from the Common Stock before the time of conversion, in which case the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all holders of Common Stock, Distributed Property as described in Section 10.06(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

Section 10.14. Increased Conversion Rate Applicable to Certain Securities Surrendered in Connection with Make-Whole Fundamental Changes . (a) Notwithstanding anything herein to the contrary, the Conversion Rate applicable to each Security that is surrendered for conversion, in accordance with this Article 10, at any time during the period (the “ Make-Whole Conversion

71

Period ”) from, and including, the effective date (the “ Effective Date ”) of a Make-Whole Fundamental Change (which Effective Date the Company shall disclose in the written notice referred to in Section 10.14(e)) (A) if such Make-Whole Fundamental Change does not also constitute a Fundamental Change, to, and including, the Close of Business on the date that is thirty (30) Business Days after the later of (i) such Effective Date and (ii) the date the Company sends to Holders the relevant notice of the Effective Date or (B) if such Make-Whole Fundamental Change also constitutes a Fundamental Change, to, and including, the Close of Business on the Fundamental Change Repurchase Date corresponding to such Fundamental Change, shall be increased to an amount equal to the Conversion Rate that would, but for this Section 10.14, otherwise apply to such Security pursuant to this Article 10, plus an amount equal to the Make-Whole Applicable Increase.

(b) As used herein, “ Make-Whole Applicable Increase ” shall mean, with respect to a Make-Whole Fundamental Change, the amount, set forth in the following table, which corresponds to the Effective Date and the Applicable Price of such Make-Whole Fundamental Change:

provided , however , that:

(i) if the actual Applicable Price of such Make-Whole Fundamental Change is between two (2) Applicable Prices listed in the table above under the row titled “Applicable Price,” or if the actual Effective Date of such Make-Whole Fundamental Change is between two Effective Dates listed in the table above in the column immediately below the title “Effective Date,” then the Make-Whole Applicable Increase for such Make-Whole Fundamental Change shall be determined by linear interpolation between the Make-Whole Applicable Increases set forth for such higher and lower Applicable Prices, or for such earlier and later Effective Dates based on a three hundred and sixty-five (365) or three hundred and sixty-six (366) day year, as applicable;

(ii) if the actual Applicable Price of such Make-Whole Fundamental Change is greater than $17.50 per share (subject to adjustment in the same manner as the Applicable Prices pursuant to Section 10.14(b)(iii)), or if the actual Applicable Price of such Make-Whole Fundamental Change is less than $3.92 per share (subject to adjustment in the same manner as the Applicable Prices pursuant to Section 10.14(b)(iii)), then the Make-Whole Applicable Increase shall be equal to zero (0);

72

(iii) if an event occurs that requires, pursuant to this Article 10 (other than solely pursuant to this Section 10.14), an adjustment to the Conversion Rate, then, on the date and at the time such adjustment is so required to be made, each Applicable Price set forth in the table above under the column titled “Applicable Price” shall be deemed to be adjusted so that such Applicable Price, at and after such time, shall be equal to the product of (A) such Applicable Price as in effect immediately before such adjustment to such Applicable Price and (B) a fraction the numerator of which is the Conversion Rate in effect immediately before such adjustment to the Conversion Rate and the denominator of which is the Conversion Rate to be in effect, in accordance with this Article 10, immediately after such adjustment to the Conversion Rate; and

(iv) each Make-Whole Applicable Increase amount set forth in the table above shall be adjusted in the same manner, for the same events and at the same time as the Conversion Rate is required to be adjusted pursuant to Section 10.06 through Section 10.13.

(c) Subject to Section 10.11, upon surrender of Securities for conversion in connection with a Make-Whole Fundamental Change, the Company shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 10.02; provided , however , that if at the effective time of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change the consideration for the Common Stock is composed entirely of cash, for any conversion of Securities following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Applicable Price for the transaction and shall be deemed to be an amount equal to, per $1,000 principal amount of converted Securities, the Conversion Rate (including any Make-Whole Applicable Increase), multiplied by such Applicable Price. In such event, the Conversion Obligation will be determined and shall be paid to Holders in cash on the third Business Day following the Conversion Date.

(d) As used herein, “ Applicable Price ” shall have the following meaning with respect to a Make-Whole Fundamental Change: (i) if such Make-Whole Fundamental Change is a transaction or series of transactions described in clause (b) of the definition of Fundamental Change and the consideration (excluding cash payments for fractional shares or pursuant to statutory appraisal rights) for Common Stock in such Make-Whole Fundamental Change consists solely of cash, then the “Applicable Price” with respect to such Make-Whole Fundamental Change shall be equal to the cash amount paid per share of Common Stock in such Make-Whole Fundamental Change and (ii) in all other circumstances, the “Applicable Price” with respect to such Make-Whole Fundamental Change shall be equal to the average of the Closing Sale Prices per share of Common Stock for the five (5) consecutive Trading Days immediately preceding, but excluding, the Effective Date of such Make-Whole Fundamental Change, which average shall be appropriately adjusted by the Board of Directors, in its good faith determination, to account for any adjustment, pursuant hereto, to the Conversion Rate that shall become effective, or any event requiring, pursuant hereto, an adjustment to the Conversion Rate where the effective date, Ex Date or expiration date of such event occurs, at any time during such five (5) consecutive Trading Days.

73

(e) The Company shall send to each Holder, in accordance with Section 14.01, written notice of the Effective Date of the Make-Whole Fundamental Change within ten (10) days after such Effective Date. Each such notice shall also state that, in connection with such Make-Whole Fundamental Change, the Company shall increase, in accordance herewith, the Conversion Rate applicable to Securities entitled as provided herein to such increase (along with a description of how such increase shall be calculated and the time periods during which Securities must be surrendered in order to be entitled to such increase, including, without limitation, the last day of the Make-Whole Conversion Period).

(f) For avoidance of doubt, the provisions of this Section 10.14 shall not affect or diminish the Company’s obligations, if any, pursuant to Article 3 with respect to a Make-Whole Fundamental Change that also constitutes a Fundamental Change.

(g) Nothing in this Section 10.14 shall prevent an adjustment to the Conversion Rate pursuant to Section 10.06 in respect of a Make-Whole Fundamental Change.

ARTICLE 11

CONCERNING THE HOLDERS

Section 11.01. Action by Holders .

The chairman of the meeting shall have no right to vote other than by virtue of Securities held by it or instruments in writing as aforesaid duly designating it as the proxy to vote on behalf of other Holders. Any meeting of Holders duly called pursuant to the provisions of Section 12.02 or Section 12.03 may be adjourned from time to time by the Holders of a majority of the aggregate principal amount of outstanding Securities represented at the meeting, whether or not constituting a quorum, and the meeting may be held as so adjourned without further notice.

Section 13.01. Optional Redemption; Election to Redeem; Notice to Trustee . Prior to April 1, 2020, the Company may not redeem the Securities. On and after April 1, 2020, the Company may, at its option, redeem the Securities for cash, in whole but not in part, upon notice pursuant to Section 13.03, at a price (the “ Redemption Price ”) equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to the Redemption Date (unless the Redemption Date falls after a Record Date but on or prior to the immediately succeeding Interest Payment Date, in which case interest accrued to the Interest Payment Date will be paid to Holders of record of such Securities on such Record Date, and the Redemption Price will be equal to 100% of the principal amount of such Securities), provided that the Closing Sale Price of the Common Stock for 20 or more Trading Days (whether or not consecutive and including the Trading Day immediately prior to the date the redemption notice is delivered to Holders) during the period of 30 consecutive Trading Days ending on, and including, the Trading Day immediately prior to the date the redemption notice is delivered to Holders is equal to or exceeds 150% of the applicable Conversion Price on each applicable Trading Day; provided further that, in the case of a redemption of any Atairos Securities in whole or in part, the Company shall have

77

on file with the SEC an effective shelf registration statement of the Company on Form S-3 (or any successor form) for an offering to be made on a delayed or continuous basis pursuant to Rule 415 under the Securities Act (or any similar rule that may be adopted by the SEC) covering the Common Stock. In addition, to the extent such Atairos Securities constitute “Registrable Securities” under the Investment Agreement, if there is a “Blackout Period” (as defined in the Investment Agreement) covering any time during the period from and including the tenth (10th) Trading Day prior to the Redemption Date to and including the Trading Day immediately prior to the Redemption Date (the “ Open Period ”) then the Company shall, as promptly as practicable, notify the Trustee and the Holders of the Atairos Securities (and, in accordance with the Investment Agreement, the beneficial owners parties thereto of the Atairos Securities) that there is such a Blackout Period, and notwithstanding anything herein to the contrary, the notice of redemption shall automatically be deemed withdrawn with respect to the Atairos Securities, and the Holders of the Atairos Securities shall have the right, upon notice to the Trustee and the Company delivered within 3 Business Days after the Withdrawal Time to rescind any Conversion Notice that is pending as of the Withdrawal Time and/or to rescind any conversion of Atairos Securities pursuant to Article 10 with respect to which the Settlement Amount has, as of the Withdrawal Time, not yet been delivered to such Holder or its designee.

Any redemption pursuant to this Section 13.01 shall be made pursuant to the provisions of this Article 13. The election of the Company to redeem the Securities pursuant to this Article 13 shall be evidenced by a Board Resolution. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction. As used herein, the “ Redemption Date ” means the date specified for redemption of the Securities in accordance with the terms of this Article 13.

No Securities may be redeemed by the Company pursuant to this Article 13 if the payment of the principal amount of the Securities has been accelerated, and such acceleration has not been rescinded by the Holders, on or prior to the Redemption Date.

Section 13.02. [Reserved] .

Section 13.03. Notice of Redemption . Notice of redemption shall be given by first-class mail, postage prepaid (or in accordance with the Applicable Procedures in the case of Global Securities), delivered not less than, as the case may be, 50 days (with respect to any redemption of Atairos Securities) or less than 30 days (with respect to any redemption of Securities other than Atairos Securities), and not more than 60 days prior to the Redemption Date, unless a shorter period is specified in the Securities to be redeemed, to each Holder of Securities to be redeemed, at its address appearing in the security register; provided, however, that the Company shall not deliver any notice of redemption to any Holder at any time when there exists any Default or Event of Default.

All notices of redemption shall identify the Securities (including CUSIP number(s)) to be redeemed and shall state:

(i) the Redemption Date;

78

(ii) the Redemption Price;

(iii) that Holders have a right to convert the Securities called for redemption upon satisfaction of the requirements set forth in Section 10.02;

(iv) the time at which the Holders’ right to convert the Securities called for redemption will expire, which will be the close of business on the Business Day immediately preceding the Redemption Date;

(v) the Conversion Rate, any adjustments thereto, and the Settlement Method that shall apply during the redemption period;

(vi) the procedures a Holder must follow to convert its Securities;

(vii) that on the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date; and

(viii) the place or places where each such Security is to be surrendered for payment of the Redemption Price.

Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s written request with 10 Business Days’ advance notice (unless a shorter period is agreed to by the Trustee), by the Trustee in the name and at the expense of the Company. Until and including the date that is 30 days prior to the Redemption Date, the Company may revoke, in whole, but not in part, any notice of redemption of Atairos Securities delivered under this Article 13.

Section 13.04. Deposit of Redemption Price . Prior to 10:00 a.m., New York City time, on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 2.04) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Securities which are to be redeemed on that date.

If any Security called for redemption is converted, any money deposited with the Trustee or with a Paying Agent or so segregated and held in trust for the redemption of such Security shall be paid to the Company on at the Company’s request, or if then held by the Company, shall be discharged from such trust.

Section 13.05. Securities Payable on Redemption Date . Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price.

79

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security.

the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Company; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustee immediately upon learning of any compromise or unauthorized use of the security procedures.
