 II. THE SECURITIES 
 2.01 FORM AND DATING. 
 The Securities and the Securities Agent’s
certificate of authentication shall be substantially in the form set forth in Exhibit A, which is incorporated in and forms a part of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange
rule or usage, provided such notations, legends or endorsements are in form reasonably acceptable to the Company. Each Security shall be dated the date of its authentication. 
 Securities offered and sold in reliance on Rule 144A shall be issued initially in the form of one or more Global Securities, substantially in the form
set forth in Exhibit A (the “Global Security”), deposited with the Securities Agent, as custodian for the Depositary, registered in the name of the Depositary or a nominee thereof, duly executed by the Company and
authenticated 
  

 -9- 

 by the Securities Agent as hereinafter provided and bearing the legends set forth in Exhibits B-1, B-2 and
B-3. The aggregate principal amount of the Global Security may from time to time be increased or decreased by adjustments made on the records of the Securities Agent, as custodian for the Depositary, as hereinafter provided; provided,
that in no event shall the aggregate principal amount of the Global Security or Securities exceed $550,000,000 (or $632,500,000 if the Initial Purchasers elect to purchase all of the Additional Securities pursuant to the Option). 
 Securities issued in exchange for interests in a Global Security pursuant to Section 2.15 may be issued in the form of permanent certificated
Securities in registered form in substantially the form set forth in Exhibit A (the “Physical Securities”) and, if applicable, bearing any legends required by Section 2.17. 
 2.02 EXECUTION AND AUTHENTICATION. 
 One duly authorized Officer shall sign the Securities for the Company by manual or facsimile signature. 
 A Security’s validity shall not be affected by the failure of an Officer whose signature is on such Security to hold, at the time the Security is
authenticated, the same office at the Company. 
 A Security shall not be valid until authenticated by the manual signature of the Securities
Agent. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture. 
 Upon a written order of
the Company signed by one Officer of the Company, the Securities Agent shall authenticate Securities for original issue in the aggregate principal amount of $550,000,000 and such additional principal amount, if any, as shall be determined pursuant
to the next sentence of this Section 2.02. Upon receipt by the Securities Agent of an Officer’s Certificate stating that the Initial Purchasers have elected to purchase from the Company a specified principal amount of Additional
Securities, not to exceed $82,500,000, pursuant to the Option, the Securities Agent shall authenticate and deliver such specified principal amount of Additional Securities to or upon the written order of the Company signed as provided in the
immediately preceding sentence. Such Officer’s Certificate must be received by the Securities Agent not later than the proposed date for delivering of such Additional Securities. The aggregate principal amount of Securities outstanding at any
time may not exceed $550,000,000 except as provided in this Section 2.02. 
 Upon a written order of the Company signed by two
(2) Officers or by an Officer and an Assistant Treasurer of the Company, the Securities Agent shall authenticate Securities not bearing the Private Placement Legend to be issued to the transferee when sold pursuant to an effective registration
statement under the Securities Act as set forth in Section 2.16(B). 
 The Securities Agent shall act as the initial
authenticating agent. Thereafter, the Securities Agent may appoint an authenticating agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Securities Agent may do so. Each
reference in this Indenture to authentication by the Securities Agent includes authentication by such authenticating agent. An authenticating agent so appointed has the same rights as the Securities Agent to deal with the Company and its Affiliates.

  

 -10- 

 If a written order of the Company pursuant to this Section 2.02 has been, or simultaneously
is, delivered, any instructions by the Company to the Securities Agent with respect to endorsement, delivery or redelivery of a Security issued in global form shall be in writing but need not comply with Section 12.04 hereof and need not
be accompanied by an Opinion of Counsel. 
 The Securities shall be issuable only in registered form without interest coupons and only in
denominations of $1,000 principal amount and any integral multiple thereof. 
 2.03 REGISTRAR, PAYING
AGENT AND CONVERSION AGENT. 
 The Company shall maintain, or shall cause to
be maintained, (i) an office or agency in the Borough of Manhattan, The City of New York, where Securities may be presented for registration of transfer or for exchange (“Registrar”), (ii) an office or agency in the
Borough of Manhattan, The City of New York, where Securities may be presented for payment (“Paying Agent”) and (iii) an office or agency in the Borough of Manhattan, The City of New York, where Securities may be presented for
conversion (“Conversion Agent”). The Registrar shall keep a register of the Securities and of their transfer and exchange. The Company may appoint or change one or more co-Registrars, one or more additional paying agents and one or
more additional conversion agents without notice and may act in any such capacity on its own behalf. The term “Registrar” includes any co-Registrar; the term “Paying Agent” includes any additional paying agent; and
the term “Conversion Agent” includes any additional conversion agent. 
 The Company shall enter into an appropriate agency
agreement with any agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee and the Securities Agent of the name and address of any such agent
not a party to this Indenture. If the Company fails to maintain a Registrar, Paying Agent or Conversion Agent, the Trustee shall act as such. 
 The Company initially appoints the Securities Agent as Paying Agent, Bid Solicitation Agent, Registrar and Conversion Agent. 
 2.04
PAYING AGENT TO HOLD MONEY IN TRUST. 
 Each Paying Agent shall hold in trust for the benefit of the Securityholders or the Trustee all moneys held by the Paying Agent for the payment of the Securities, and shall notify the Trustee of any Default by the Company in making any such
payment. While any such Default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and account for any funds so
paid by it. Upon payment over to the Trustee, the Paying Agent shall have no further liability for such money. If the Company acts as Paying Agent, it shall segregate and hold as a separate trust fund all money held by it as Paying Agent.

  

 -11- 

 2.05 SECURITYHOLDER LISTS. 
 The Securities Agent shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of
Securityholders. If the Securities Agent is not the Registrar, the Company shall furnish, or shall cause to be furnished, to the Trustee and the Securities Agent on or before each interest payment date and at such other times as the Trustee or the
Securities Agent may request in writing a list, in such form and as of such date as the Trustee or the Securities Agent, as the case may be, may reasonably require, of the names and addresses of Securityholders appearing in the security register of
the Registrar. 
 2.06 TRANSFER AND EXCHANGE. 
 Subject to Sections 2.15 and 2.16 hereof, where Securities are presented to the Registrar with a request to register their transfer or to
exchange them for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange if its requirements for such transaction are met. To permit registrations of transfer and
exchanges, the Securities Agent shall authenticate Securities at the Registrar’s request or upon the Securities Agent’s receipt of a Company Order therefor. The Company or the Securities Agent, as the case may be, shall not be required to
register the transfer of or exchange any Security (i) for a period of twenty (20) days before selecting, pursuant to Section 3.03, Securities to be redeemed or (ii) during a period beginning at the opening of business
twenty (20) days before the mailing of a notice of redemption of the Securities selected for Redemption under Section 3.04 and ending at the close of business on the day of such mailing or (iii) that has been selected for
Redemption or for which a Purchase Notice has been delivered, and not withdrawn, in accordance with this Indenture, except the unredeemed or unrepurchased portion of Securities being redeemed or repurchased in part. 
 No service charge shall be made for any transfer, exchange or conversion of Securities, but the Company or the Securities Agent may require payment of a
sum sufficient to cover any 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 Sections 2.10, 9.05 or 10.02, or
Article III, not involving any transfer. 
 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 Securities
Agent shall authenticate a replacement Security upon surrender to the Securities Agent of the mutilated Security, or upon delivery to the Securities Agent of evidence of the loss, destruction or theft of the Security satisfactory to the Securities
Agent and the Company. In the case of a lost, destroyed or wrongfully taken Security, if required by the Securities Agent or the Company, an indemnity bond must be provided by the Holder that is reasonably satisfactory to the Securities Agent, the
Trustee and the Company to indemnify and hold harmless the Company, the Trustee and the Securities Agent from any loss which any of them may suffer if such Security is replaced. The Securities Agent and the Company may charge such Holder for their
expenses in replacing a Security. 
  

 -12- 

 In case any such mutilated, lost, destroyed or wrongfully taken Security has become or is about to become
due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security when due. 
 Every replacement
Security is an additional obligation of the Company only as provided in Section 2.08. 
 2.08 OUTSTANDING
SECURITIES. 
 Securities outstanding at any time are all the Securities authenticated by the Securities Agent 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 Securities Agent receives proof satisfactory to it, or a court holds, that the replaced Security is held by a protected purchaser. 
 If the Paying Agent (other than the Company) holds on an Option Purchase Date, Redemption Date, Fundamental Change Repurchase Date or Maturity Date,
money sufficient to pay the aggregate Option Purchase Price, Redemption Price, Fundamental Change Repurchase Price or principal amount, as the case may be, with respect to all Securities to be redeemed, purchased or paid upon Purchase at
Holder’s Option, Redemption, Repurchase Upon Fundamental Change or maturity, as the case may be, in each case plus, if applicable, accrued and unpaid interest, if any, payable as herein provided upon Purchase at Holder’s Option,
Redemption, Repurchase Upon Fundamental Change or maturity, then (unless there shall be a Default in the payment of such aggregate Option Purchase Price, Redemption Price, Fundamental Change Repurchase Price or principal amount, or of such accrued
and unpaid interest), except as otherwise provided herein, 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 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 Option Purchase Price, Redemption Price, Fundamental
Change Repurchase Price or principal amount, as the case may be, plus, if applicable, such accrued and unpaid interest, in accordance with this Indenture. Notwithstanding the foregoing, a Holder shall be entitled to convert a Security on the
Maturity Date, provided such Security has not been surrendered for payment upon maturity. 
 If a Security is converted in accordance
with Article X, 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 hereunder upon such conversion. 
 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, Securities owned by the Company 
  

 -13- 

 or any of its Subsidiaries or Affiliates shall be considered as though not outstanding, except that, for the purposes of
determining whether a Responsible Officer of the Trustee or the Securities Agent, as applicable, shall be protected in relying on any such direction, waiver or consent, only Securities which the Trustee or the Securities Agent, as applicable, 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 or the
Securities Agent, as applicable, the pledgee’s right so to 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 or an affiliate of any such other obligor. In the event of a dispute as to whether the pledgee has established the foregoing, the Trustee and the Securities Agent may rely on the advice of counsel or on an Officer’s Certificate.

 2.10 TEMPORARY SECURITIES. 
 Until definitive Securities are ready for delivery, the Company may prepare and the Securities Agent shall, upon receipt of a Company Order, 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 Securities Agent, upon receipt of a Company
Order, 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. 
 2.11
CANCELLATION. 
 The Company at any time may deliver Securities to the Securities Agent for cancellation. The Trustee,
Registrar, Paying Agent and Conversion Agent shall forward to the Securities Agent any Securities surrendered to them for transfer, exchange, payment or conversion. The Securities Agent 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 Securities Agent for cancellation or that any
Securityholder has converted pursuant to Article X. All cancelled Securities held by the Securities Agent shall be destroyed, and certification of their destruction shall be delivered by the Securities Agent to the Company unless the Company
shall, by a Company Order, direct that cancelled Securities be returned to it. 
 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 Securityholders on a subsequent special record date. The Company shall fix such record date and payment date. At least fifteen (15) calendar days before the record date, the Company shall mail to
Securityholders a notice that states the record date, payment date and amount of interest to be paid. Upon the due payment in full, interest shall no longer accrue on such defaulted interest pursuant to this Section 2.12. 
  

 -14- 

 2.13 CUSIP NUMBERS. 
 The Company in issuing the Securities may use one or more “CUSIP” numbers, and, if so, the Trustee and the Securities Agent shall use the CUSIP
numbers in notices of redemption or exchange as a convenience to Holders; provided, however, that no representation is hereby deemed to be made by the Trustee or the Securities Agent as to the correctness or accuracy of the CUSIP
numbers printed on the notice or on the Securities; 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 and the Securities Agent of any change in the CUSIP numbers. 
 2.14 DEPOSIT OF MONEYS. 
 Prior to 11:00 A.M., New York City time, on
each interest payment date, Maturity Date, Redemption Date, Option Purchase Date or Fundamental Change Repurchase Date, the Company shall have deposited 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, Maturity Date, Redemption Date, Option Purchase Date or Fundamental
Change Repurchase 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, Maturity Date, Redemption Date, Option Purchase Date or Fundamental Change Repurchase Date,
as the case may be. 
 2.15 BOOK-ENTRY PROVISIONS FOR GLOBAL
SECURITIES. 
 (A) The Global Securities initially shall (i) be registered in the name of the Depositary or the
nominee of the Depositary, (ii) be delivered to the Securities Agent as custodian for the Depositary and (iii) bear legends as set forth in Section 2.17. 
 Members of, or participants in, the Depositary (“Participants”) shall have no rights under this Indenture with respect to any Global
Security held on their behalf by the Depositary, or the Securities Agent as its custodian, or under the Global Security, and the Depositary may be treated by the Company, the Trustee and the Securities Agent and any agent of the Company, the Trustee
and the Securities Agent as the absolute owner of the Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee, the Securities Agent or any agent of the Company, the Trustee or
the Securities Agent from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and Participants, the operation of customary practices governing the exercise of the
rights of a Holder of any Security. 
 (B) Transfers of Global Securities shall be limited to transfers in whole, but not in part, to the
Depositary, its successors or their respective nominees. In addition, Physical Securities shall be transferred to all beneficial owners, as identified by the Depositary, in 
  

 -15- 

 exchange for their beneficial interests in Global Securities only if (i) the Depositary notifies the Company that
the Depositary is unwilling or unable to continue as depositary for any Global Security (or the Depositary ceases to be a “clearing agency” registered under Section 17A of the Exchange Act) and a successor Depositary 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 Depositary to issue Physical Securities. 
 (C) 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 Securities Agent for cancellation, and the Company shall execute, and the Securities Agent shall upon written instructions from the Company authenticate and deliver, to each beneficial owner
identified by the Depositary in exchange for its beneficial interest in such Global Security, an equal aggregate principal amount of Physical Securities of authorized denominations. 
 (D) Any Physical Security constituting a Restricted Security delivered in exchange for an interest in a Global Security pursuant to
Section 2.15(B) shall, except as otherwise provided by Section 2.16, bear the Private Placement Legend. 
 (E) 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. 
 2.16 SPECIAL TRANSFER PROVISIONS. 
 (A) Restrictions on Transfer and Exchange of Global Securities. 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 Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or
any such nominee to a successor Depositary or a nominee of such successor Depositary. 
 (B) Private Placement Legend. Upon the
transfer, exchange or replacement of Securities not bearing the Private Placement Legend, the Registrar or co-Registrar shall deliver Securities that do not bear the Private Placement Legend. Upon the transfer, exchange or replacement of Securities
bearing the Private Placement Legend, the Registrar or co-Registrar shall deliver only Securities that bear the Private Placement Legend unless (i) the requested transfer is after the Resale Restriction Termination Date, (ii) there is
delivered to the Trustee, the Securities Agent and the Company an opinion of counsel reasonably satisfactory to the Company and addressed to the Company to the effect that neither such legend nor the related restrictions on transfer are required in
order to maintain compliance with the provisions of the Securities Act or (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 or co-Registrar a notice in the form of Exhibit C hereto. Upon the effectiveness, under the Securities Act, of the “Shelf Registration Statement” (as defined in the Registration Rights Agreement), the Company shall deliver
to the Trustee and the Securities Agent a notice of effectiveness, a Global Security or Global Securities, which do not bear the Private Placement Legend, an authentication order in accordance with Section 2.02 and an Opinion of Counsel
in the form of Exhibit D 
  

 -16- 

 hereto, and, if required by the Depositary, the Company shall deliver to the Depositary a letter of representations in a
form reasonably acceptable to the Depositary. Upon the effectiveness of any post-effective amendment to the “Shelf Registration Statement” (as defined in the Registration Rights Agreement) and upon the effectiveness, under the Securities
Act, of any “Subsequent Shelf Registration Statement” (as defined in the Registration Rights Agreement), the Company shall deliver to the Trustee and the Securities Agent a notice of effectiveness and an Opinion of Counsel in the form of
Exhibit D hereto. Upon any sale, pursuant to a Shelf Registration Statement, of a beneficial interest in a Global Security that theretofore constituted a Restricted Security and delivery of appropriate evidence thereof to the Trustee and the
Securities Agent, and upon any sale or transfer of a beneficial interest in connection with which the Private Placement Legend will be removed in accordance with this Indenture, the Securities Agent shall increase the principal amount of the Global
Security that does not constitute a Restricted Security by the principal amount of such sale or transfer and likewise reduce the principal amount of the Global Security that does constitute a Restricted Security. 
 (C) General. By its acceptance of any Security bearing the Private Placement Legend, each Holder of such a Security acknowledges the restrictions
on transfer of such Security set forth in this Indenture and in the Private Placement Legend 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. 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. 
 (D) Transfers of Securities Held by Affiliates. Any certificate (i) evidencing a Security that has been transferred to an Affiliate within
two (2) years after the Issue Date, as evidenced by a notation on the assignment form for such transfer or in the representation letter delivered in respect thereof or (ii) evidencing a Security that has been acquired from an Affiliate
(other than by an Affiliate) in a transaction or a chain of transactions not involving any public offering, shall, until two (2) years after the last date on which the Company or any Affiliate was an owner of such Security (or such longer
period of time as may be required under the Securities Act or applicable state securities laws), in each case, bear the Private Placement Legend, unless otherwise agreed by the Company (with written notice thereof to the Trustee and the Securities
Agent). 
 2.17 RESTRICTIVE LEGENDS. 
 Each Global Security and Physical Security that constitutes a Restricted Security shall bear the legend (the “Private Placement Legend”)
as set forth in Exhibit B-1 on the face thereof until after the second anniversary of the later of (i) the Issue Date and (ii) the last date on which the Company or any Affiliate was the owner of such Security (or any predecessor
security) (or such shorter period of time as permitted by Rule 144(k) under the Securities Act or any successor provision thereunder) (or such longer period of time as may be required under the Securities Act or applicable state securities laws, as
set forth in an Opinion of Counsel, unless otherwise agreed between the Company and the Holder thereof) (such date, the “Resale Restriction Termination Date”). 
  

 -17- 

 Each Global Security shall also bear the legend as set forth in Exhibit B-2. 
 Each Global Security and Physical Security shall also bear the legend (the “Tax Legend”) set forth in Exhibit B-3. 
 2.18 RANKING. 
 The indebtedness
of the Company arising under or in connection with this Indenture and every outstanding Security issued under this Indenture from time to time constitutes and will constitute a senior unsecured obligation of the Company, ranking equally with other
existing and future senior unsecured indebtedness of the Company and ranking senior to any existing or future subordinated indebtedness of the Company. 
 III. REDEMPTION AND REPURCHASE 
 3.01 RIGHT OF
REDEMPTION. 
 (A) Redemption of the Securities, as permitted by any provision of this Indenture, shall be made:

 (i) with respect to a repurchase at the Company’s option, in accordance with paragraphs 6 and 7 of the
Securities (a “Redemption”), 
 (ii) with respect to a repurchase at the Holder’s option, in accordance
with paragraph 8 of the Securities (a “Purchase at Holder’s Option”) and 
 (iii) with respect to
any repurchase upon a Fundamental Change, in accordance with paragraph 9 of the Securities (a “Repurchase Upon Fundamental Change”), 
 in each case in accordance with the applicable provisions of this Article III. 
 (B) The Company will

Redemption Date be a Legal Holiday; provided further, that if the Redemption Date with respect to a Security is after a record date for the payment of an installment of interest and on or before the related interest payment date, then accrued
and unpaid interest to, but excluding, 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, and the Holder surrendering such Security for
Redemption shall not be entitled to any such interest unless such Holder was also the Holder of record of such Security at the close of business on such record date.

 (D) Securities in denominations larger than $1,000 principal amount may be redeemed in part but only in
integral multiples of $1,000 principal amount. 
 3.02 NOTICES TO TRUSTEE AND
THE SECURITIES AGENT. 
 If the Company elects to redeem Securities pursuant to paragraph
6 of the Securities, it shall notify the Trustee and the Securities Agent of the Redemption Date, the applicable provision of this Indenture pursuant to which the Redemption is to be made and the aggregate principal amount of Securities to be
redeemed, which notice shall be provided to the Trustee and the Securities Agent by the Company at least fifteen (15) days (or, in the case of a Serologicals Redemption, one (1) Business Day) prior to the mailing, in accordance with
Section 3.04, of the notice of Redemption (unless a shorter notice period shall be satisfactory to the Trustee and the Securities Agent). 
 3.03 SELECTION OF SECURITIES TO BE REDEEMED. 
 If the Company has elected to redeem less than all the Securities pursuant to paragraph 6 of the Securities, the Securities Agent shall, within five (5) Business Days after receiving the notice specified
in Section 3.02, select the Securities to be redeemed by lot, on a pro rata basis or in accordance with any other method the Securities Agent considers fair and appropriate. The Securities Agent shall make such selection from
Securities then outstanding and not already to be redeemed by virtue of having been previously called for Redemption. The Securities Agent may select for Redemption portions of the principal amount of Securities that have denominations larger than
$1,000 principal amount. Securities and portions of them the Securities Agent selects for Redemption shall be in amounts of $1,000 principal amount or integral multiples of $1,000 principal amount. The Securities Agent shall promptly notify the
Company in writing of the Securities selected for Redemption and the principal amount thereof to be redeemed. 
 The Registrar need not
register the transfer of or exchange any Securities that have been selected for Redemption, except the unredeemed portion of the Securities being redeemed in part. The Registrar need not issue, authenticate, register the transfer of or exchange any
Security for a period of twenty (20) days before selecting, pursuant to this Section 3.03, Securities to be redeemed. 
 3.04
NOTICE OF REDEMPTION. 
 At least thirty (30) days but not more than sixty
(60) days before a Redemption Date (or, with respect to a Serologicals Redemption, not less than seven (7) nor more than thirty (30) days before the applicable Redemption Date), the Company shall mail, or cause to be mailed, by
first-class mail a notice of Redemption to each Holder whose Securities are to be redeemed, at the address of such Holder appearing in the security register. 
 The notice shall identify the Securities and the aggregate principal amount thereof to be redeemed pursuant to the Redemption and shall state:

 -19- 

 (ii) the Redemption Price plus accrued and unpaid interest, if any, to, but excluding,
the Redemption Date; 
 (iii) the Conversion Rate and the Conversion Price; 
 (iv) the names and addresses of the Paying Agent and the Conversion Agent; 
 (v) that the right to convert the Securities called for Redemption will terminate at the close of business on the third
(3rd) Business Day immediately preceding the Redemption Date, unless there shall be a Default in the payment of the Redemption Price or accrued and unpaid interest, if any, payable as herein provided upon Redemption; 
 (vi) that Holders who want to convert Securities must satisfy the requirements of Article X; 
 (vii) the paragraph of the Securities pursuant to which the Securities are to be redeemed; 
 (viii) that Securities called for Redemption must be surrendered to the Paying Agent to collect the Redemption Price plus accrued and
unpaid interest, if any, payable as herein provided upon Redemption; 
 (ix) that, unless there shall be a Default in the
payment of the Redemption Price or accrued and unpaid interest, if any, payable as herein provided upon Redemption (including, where the Redemption Date is after a record date for the payment of an installment of interest and on or before the
related interest payment date, the payment, on such interest payment date, of accrued and unpaid interest to, but excluding, such interest payment date to the Holder of record at the close of business on such record date), interest on Securities
called for Redemption ceases to accrue on and after the Redemption Date, except as otherwise provided herein, such Securities will cease to be convertible after the close of business on the third (3rd) Business Day immediately preceding the
Redemption Date, and all rights of the Holders of such Securities shall terminate on and after the Redemption Date, other than the right to receive, upon surrender of such Securities and in accordance with this Indenture, the amounts due hereunder
on such Securities upon Redemption (and the rights of the Holder(s) of record of such Securities to receive, on the applicable interest payment date, accrued and unpaid interest in accordance herewith in the event the Redemption Date is after a
record date for the payment of an installment of interest and on or before the related interest payment date); and 
 (x) the
CUSIP number or numbers, as the case may be, of the Securities. 
 The right, pursuant to Article X, to convert Securities called for
Redemption shall terminate at the close of business on the third (3rd) Business Day immediately preceding the Redemption Date, unless there shall be a Default in the payment of the Redemption Price or accrued and unpaid interest, if any,
payable as herein provided upon Redemption. 
  

 -20- 

 At the Company’s request, upon reasonable prior notice, the Securities Agent shall mail the notice
of Redemption in the Company’s name and at the Company’s expense; provided, however, that the form and content of such notice shall be prepared by the Company. 
 3.05 EFFECT OF NOTICE OF REDEMPTION. 
 Once notice of Redemption is mailed, Securities called for Redemption become due and payable on the Redemption Date at the consideration set forth herein, and, on and after such Redemption Date (unless there shall be
a Default in the payment of such consideration), except as otherwise provided herein, such Securities shall cease to bear interest, and all rights of the Holders of such Securities shall terminate, other than the right to receive such consideration
upon surrender of such Securities to the Paying Agent. 
 If any Security shall not be fully and duly paid in accordance herewith upon
Redemption, the principal of, and accrued and unpaid interest on, such Security shall, until paid, bear interest at the rate borne by such Security on the principal amount of such Security, and such Security shall continue to be convertible pursuant
to Article X. 
 Notwithstanding anything herein to the contrary, there shall be no purchase of any Securities pursuant to a
Redemption if there has occurred (prior to, on or after, as the case may be, the mailing of the notice of Redemption specified in Section 3.04) and is continuing an Event of Default (other than a Default in the payment of the
consideration payable as herein provided upon Redemption). The Paying Agent will promptly return to the respective Holders thereof any Securities held by it during the continuance of such an Event of Default. 
 3.06 DEPOSIT OF REDEMPTION PRICE. 
 Prior to 11:00 A.M., New York City time on the 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 the Redemption Date, sufficient to pay the consideration payable as herein provided upon Redemption on all Securities to
be redeemed on that date. The Paying Agent shall return to the Company, as soon as practicable, any money not required for that purpose. 
 3.07
SECURITIES REDEEMED IN PART. 
 Any Security to be submitted for Redemption
only in part shall be delivered pursuant to Section 3.05 (with, if the Company or the Securities Agent so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Securities Agent duly
executed by, the Holder thereof or its attorney duly authorized in writing, with a medallion guarantee), and the Company shall execute, and the Securities Agent shall authenticate and make available for delivery to the Holder of such Security
without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder, of the same tenor and in aggregate principal amount equal to the portion of such Security not submitted for Redemption. 
  

 -21- 

 If any Security selected for partial Redemption is converted in part, the principal of such Security
subject to Redemption shall be reduced by the principal amount of such Security that is converted. 
 3.08 REDEMPTION
UPON FAILURE TO CONSUMMATE THE SEROLOGICALS MERGER TRANSACTION. 
 If the Serologicals Merger is not consummated, then the Company shall have the right, at the Company’s option, at any time, and from time to time, on
a Redemption Date on or before October 10, 2006, to redeem (a “Serologicals Redemption”) all or any part of the Securities at a price payable in cash equal to one hundred and one percent (101%) of the principal amount of
the Securities to be so redeemed, plus the Conversion Premium, if any, plus any accrued and unpaid interest to, but excluding, such Redemption Date. The requirements applicable to a Redemption pursuant to Sections 3.01(A)(i) and 3.01(C) shall
also apply to each Serologicals Redemption, except that, for purposes solely of a Serologicals Redemption, the term “Redemption Price” shall be deemed to mean an amount equal to one hundred and one percent (101%) of the principal
amount of the Securities to be redeemed, plus the Conversion Premium, if any. 
 “Conversion Premium” means, per $1,000
principal amount of the Securities, an amount equal to eighty percent (80%) of the excess, if any, of the Serologicals Conversion Value over seven hundred fourteen dollars and twenty nine cents ($714.29). The Conversion Premium shall be
calculated by the Company. Neither the Trustee nor the Securities Agent shall have any duty or obligation to verify or recalculate the Conversion Premium so calculated by the Company. 
 “Serologicals Conversion Value” means, with respect to a Serologicals Redemption, the Conversion Rate in effect on the Redemption Date
of such Serologicals Redemption multiplied by the average of the Volume-Weighted Average Price per share Common Stock for the five (5) consecutive Trading Days immediately preceding such Redemption Date, which average shall be appropriately
adjusted by the Board of Directors, in its good faith determination (which determination shall be described in a Board Resolution), 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 Ex Date of such event occurs, at any time during such five (5) consecutive Trading Days. 
 “Volume-Weighted Average Price” per share of Common Stock on a Trading Day means the volume-weighted average price per share of Common Stock on the New York Stock Exchange or, if the Common Stock is
not then listed on the New York Stock Exchange, on the principal exchange or over-the-counter market on which the Common Stock is then listed or traded, from 9:30 a.m. to 4:00 p.m., New York City time, on such Trading Day, as displayed by Bloomberg;
provided, however, that if such volume-weighted average price is not available, then the Board Of Directors shall in good faith determine the amount to be used as the Volume-Weighted Average Price, which determination shall be described in a
Board Resolution.

 -23- 

 Notwithstanding anything herein to the contrary, any Holder that has delivered the Purchase Notice
contemplated by this Section 3.09(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 Option Purchase Notice shall have the right to withdraw such Purchase

such Option Purchase Price or in accrued and unpaid interest, if any, payable as herein provided upon Purchase at Holder’s Option; 
 (iv) that Securities (together with any necessary endorsements) must be surrendered to the Paying Agent to collect payment of the Option Purchase Price plus (if such Holder was the Holder of record of the applicable

as described in clause (iv) above; provided, however, that such accrued and unpaid interest shall be paid, on the applicable interest payment date, to the Holder of record of such Security at the close of business on the
record date immediately preceding such Option Purchase Date; 
  

 -24-

Section 3.09 (including the name and address of the Paying Agent) and a brief description of those rights; 
 (vii) that a Holder will be entitled to withdraw its election in the Purchase Notice if the Company (if acting as its own Paying Agent) or the Paying Agent receives, at any time prior to the close of business on the third
(3rd) Business Day immediately preceding the applicable Option Purchase Date, or such longer period as may be required by law, a letter or telegram, telex or facsimile transmission (receipt of which is confirmed and promptly followed by a
letter) setting forth (I) the name of such Holder, (II) a statement that such Holder is withdrawing its election to have Securities purchased by the Company on such Option Purchase Date pursuant to a Purchase at Holder’s Option, (III) the
certificate number(s) of such Securities to be so withdrawn, if such Securities are in certificated form, (IV) the principal amount of the Securities of such Holder to be so withdrawn, which amount must be $1,000 or an integral multiple thereof and
(V) the principal amount, if any, of the Securities of such Holder that remain subject to the Purchase Notice delivered by such Holder in accordance with this Section 3.09, which amount must be $1,000 or an integral multiple
thereof; 
 (viii) that on and after the applicable Option Purchase Date (unless there shall be a Default in the payment of
the consideration payable as herein provided upon a Purchase at Holder’s Option), interest on Securities subject to Purchase at Holder’s Option will cease to accrue, and all rights of the Holders of such Securities shall terminate, other
than the right to receive, in accordance herewith, the consideration payable as herein provided upon a Purchase at Holder’s Option; and 
 (ix) the CUSIP number or numbers, as the case may be, of the Securities. 
 At the Company’s request,
upon reasonable prior notice, the Securities Agent shall mail such Option Purchase Notice in the Company’s name and at the Company’s expense; provided, however, that the form and content of such Option Purchase Notice shall be
prepared by the Company. 
 No failure of the Company to give an Option Purchase Notice shall limit any Holder’s right pursuant hereto
to exercise its rights to require the Company to purchase such Holder’s Securities pursuant to a Purchase at Holder’s Option. 
 (C) Subject to the provisions of this Section 3.09, the Company shall pay, or cause to be paid, the Option Purchase Price, plus accrued and unpaid interest, if any, to, but excluding, the applicable Option Purchase Date, with

Security (together with all necessary endorsements) is surrendered to the Paying Agent; provided, however, that such accrued and unpaid interest shall be paid, on the applicable interest payment date, to the Holder of record of such
Security at the close of business on the record date immediately preceding such Option Purchase Date. 
  

 -25- 

 (D) Prior to 11:00 A.M., New York City time on the applicable Option Purchase 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 the applicable Option Purchase Date, sufficient to
pay the Option Purchase Price, plus accrued and unpaid interest, if any, to, but excluding, such Option Purchase Date, of all of the Securities that are to be purchased by the Company on such Option Purchase Date pursuant to a Purchase at
Holder’s Option. The Paying Agent shall return to the Company, as soon as practicable, any money not required for that purpose. 
 (E)
Once the Purchase Notice has been duly delivered in accordance with this Section 3.09, the Securities to be purchased pursuant to the Purchase at Holder’s Option shall, on the applicable Option Purchase Date, become due and payable
in accordance herewith, and, on and after such date (unless there shall be a Default in the payment of the consideration payable as herein provided upon a Purchase at Holder’s Option), such Securities shall cease to bear interest, and all
rights of the Holders of such Securities shall terminate, other than the right to receive, in accordance herewith, the such consideration. 
 (F) Securities with respect to which a Purchase Notice has been duly delivered in accordance with this Section 3.09 may be converted pursuant to Article X, if otherwise convertible in accordance with Article X,

 (G) If any Security subject to Purchase at Holder’s Option shall not be paid in accordance herewith, the principal of, and accrued and unpaid
interest on, such Security shall, until paid, bear interest, payable in cash, at the rate borne by such Security on the principal amount of such Security, and such Security shall continue to be convertible pursuant to Article X. 

(H) Any Security which is to be submitted for Purchase at Holder’s Option only in part shall be delivered pursuant to this
Section 3.09 (with, if the Company or the Securities Agent so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Securities Agent duly executed by, the Holder thereof or its
attorney duly authorized in writing, with a medallion guarantee), and the Company shall execute, and the Securities Agent shall authenticate and make available for delivery to the Holder of such Security without service charge, a new Security or
Securities, of any authorized denomination as requested by such Holder, of the same tenor and in aggregate principal amount equal to the portion of such Security not submitted for Purchase at Holder’s Option. 
 (I) Notwithstanding anything herein to the contrary, there shall be no purchase of any Securities pursuant to this Section 3.09 if there has
occurred (prior to, on or after, as the case may be, the giving, by the Holders of such Securities, of the required Purchase Notice) and is continuing an Event of Default (other than a Default in the payment of the consideration payable as herein
provided upon a Purchase at Holder’s Option or a Default arising from the Company’s failure to provide the applicable Option Purchase Notice). The Paying Agent will promptly return to the respective Holders thereof any Securities held by
it during the continuance of an Event of Default (other than a Default in the payment of such consideration or arising from the Company’s failure to provide the applicable Option Purchase Notice). 
  

 -26- 

 (J) Notwithstanding anything herein to the contrary, if the option granted to Holders to require the

and with all other applicable laws, and will file a Schedule TO or any other schedules required under the Exchange Act or any other applicable laws. 
 3.10 REPURCHASE AT OPTION OF HOLDER UPON A FUNDAMENTAL CHANGE. 
 (A) In the event any Fundamental Change (as defined below) shall occur, each Holder of Securities shall have the right (the “Fundamental Change

Securities at the close of business on such record date (without any surrender of such Securities by such Holder), and the Holder surrendering such Securities for repurchase will not be entitled to any such accrued and unpaid interest unless such
Holder was also the Holder of record of such Securities at the close of business on such record date. 
 If such Securities are held in
book-entry form through the Depositary, the Purchase Notice shall comply with applicable procedures of the Depositary. 
 Upon such delivery
of Securities to the Company (if it is acting as its own Paying Agent) or such Paying Agent, such Holder shall be entitled to receive, upon request, from the Company or such Paying Agent, as the case may be, a nontransferable receipt of deposit
evidencing such delivery.

 The Paying Agent shall promptly
notify the Company of the receipt by it of any Purchase Notice or written notice of withdrawal thereof.

Repurchase Date and the time of delivery of the Security (together with all necessary endorsements) as described in clause (viii) above; 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 accrued and unpaid interest, if any, to, but excluding, such interest payment date will be paid on such interest payment date to the
Holder of record of such Security at the close of business on such record date (without any surrender of such Securities by such Holder), and the Holder surrendering such Security for repurchase will not be entitled to any such accrued and unpaid
interest unless such Holder was also the Holder of record of such Security at the close of business on such record date; 
 (x) that, except as otherwise provided herein with respect to a Fundamental Change Repurchase Date that is after a record date for the payment of an installment of interest and on or before the related interest payment date, on and after
such Fundamental Change Repurchase Date (unless there shall be a Default in the payment of the consideration payable as herein provided upon Repurchase Upon Fundamental Change), interest on Securities subject to Repurchase Upon Fundamental Change
will cease to accrue, and all rights of the Holders of such Securities shall terminate, other than the right to receive, in accordance herewith, the consideration payable as herein provided upon Repurchase Upon Fundamental Change; 
 (xi) that a Holder will be entitled to withdraw its election in the Purchase Notice if the Company (if acting as its own Paying Agent), or

 (xiii) that
Securities with respect to which a Purchase Notice is given by a Holder may be converted pursuant to Article X, if otherwise convertible in accordance with Article X, only if such Purchase Notice has been withdrawn in accordance with

(xiv) the CUSIP number or numbers, as the case may be, of the Securities. 
 At the Company’s request, upon reasonable prior notice, the Securities Agent shall mail such Fundamental Change Notice in the Company’s name
and at the Company’s expense; provided, however, that the form and content of such Fundamental Change Notice shall be prepared by the Company. 
 No failure of the Company to give a Fundamental Change Notice shall limit any Holder’s right pursuant hereto to exercise a Fundamental Change Repurchase Right. 
 (C) Subject to the provisions of this Section 3.10, the Company shall pay, or cause to be paid, the Fundamental Change Repurchase Price, plus
accrued and unpaid interest, if any, to, but excluding, the Fundamental Change Repurchase Date, with respect to each Security as to which the Fundamental Change Repurchase Right shall have been exercised to the Holder thereof as promptly as
practicable, but in no event later than the third (3rd) Business Day after the later of the Fundamental Change Repurchase Date and the time such Security is surrendered to the Paying Agent; 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 accrued and unpaid interest, if any, to, but excluding, such interest payment date
will be paid on such interest payment date to the Holder of record of such Security at the close of business on such record date, and the Holder surrendering such Security for repurchase will not be entitled to any such accrued and unpaid interest
unless such Holder was also the Holder of record of such Security at the close of business on such record date. 
 (D) Prior to 11:00 A.M.,
New York City time on a Fundamental Change Repurchase 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

  

 -30- 

 immediately available on the Fundamental Change Repurchase Date, sufficient to pay the consideration payable as herein
provided upon Repurchase Upon Fundamental Change for all of the Securities that are to be repurchased by the Company on such Fundamental Change Repurchase Date pursuant to a Repurchase Upon Fundamental Change. The Paying Agent shall return to the
Company, as soon as practicable, any money not required for that purpose. 
 (E) Once the Fundamental Change Notice and the Purchase Notice
have been duly given in accordance with this Section 3.10, the Securities to be repurchased pursuant to a Repurchase Upon Fundamental Change shall, on the Fundamental Change Repurchase Date, become due and payable in accordance herewith,
and, on and after such date (unless there shall be a Default in the payment of the consideration payable as herein provided upon Repurchase Upon Fundamental Change), except as otherwise provided herein with respect to a Fundamental Change Repurchase
Date that is after a record date for the payment of an installment of interest and on or before the related interest payment date, such Securities shall cease to bear interest, and all rights of the Holders of such Securities shall terminate, other
than the right to receive, in accordance herewith, such consideration. 
 (F) Securities with respect to which a Purchase Notice has been
duly delivered in accordance with this Section 3.10 may be converted pursuant to Article X, if otherwise convertible in accordance with Article X, only if such Purchase Notice has been withdrawn in accordance with this
Section 3.10 or if there shall be a Default in the payment of the consideration payable as herein provided upon Repurchase Upon Fundamental Change. 
 (G) If any Security shall not be paid upon surrender thereof for Repurchase Upon Fundamental Change, the principal of, and accrued and unpaid interest on, such Security shall, until paid, bear interest, payable in
cash, at the rate borne by such Security on the principal amount of such Security, and such Security shall continue to be convertible pursuant to Article X. 
 (H) Any Security which is to be submitted for Repurchase Upon Fundamental Change only in part shall be delivered pursuant to this Section 3.10 (with, if the Company or the Securities Agent so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Securities Agent duly executed by, the Holder thereof or its attorney duly authorized in writing, with a medallion guarantee), and the Company shall
execute, and the Securities Agent shall authenticate and make available for delivery to the Holder of such Security without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder, of the same tenor
and in aggregate principal amount equal to the portion of such Security not duly submitted for Repurchase Upon Fundamental Change. 
 (I)
Notwithstanding anything herein to the contrary, there shall be no purchase of any Securities pursuant to this Section 3.10 if there has occurred (prior to, on or after, as the case may be, the giving, by the Holders of such Securities,
of the required Purchase Notice) and is continuing an Event of Default (other than a Default in the payment of the consideration payable as herein provided upon Repurchase Upon Fundamental Change or a Default arising from the Company’s failure
to provide the applicable Fundamental Change Notice). The Paying Agent will promptly return to the respective Holders thereof any Securities held by it during the continuance of an Event of Default (other than a Default in the payment of such
consideration or arising from the Company’s failure to provide the applicable Fundamental Change Notice). 
  

 -31- 

 (J) Notwithstanding anything herein to the contrary, if the option granted to Holders to require the
repurchase of the Securities upon the occurrence of a Fundamental Change is determined to constitute a tender offer, the Company shall comply with all applicable tender offer rules under the Exchange Act, including Rule 13e-4 and Regulation 14E
thereunder, and with all other applicable laws, and will file a Schedule TO or any other schedules required under the Exchange Act or any other applicable laws. 
 (K) As used herein and in the Securities, a “Fundamental Change” shall be deemed to have occurred upon the occurrence of either a “Change in Control” or a “Termination of Trading.”

 (i) A “Change in Control” shall be deemed to have occurred at such time as: 
 (a) any “person” or “group” (as such terms are used in Sections 13(d) and 14(d) of the Exchange Act) is or becomes the
“beneficial owner” (as such term is used in Rule 13d-3 under the Exchange Act), directly or indirectly, of fifty percent (50%) or more of the total outstanding voting power of all classes of the Company’s Capital Stock entitled
to vote generally in the election of directors (such an event, an “Acquisition of Voting Control”); or 
 (b)
there occurs a sale, transfer, lease, conveyance or other disposition (other than a Permitted Transfer) of all or substantially all of the property or assets of the Company to any “person” or “group” (as such terms are used in
Sections 13(d) and 14(d) of the Exchange Act), including any group acting for the purpose of acquiring, holding, voting or disposing of securities within the meaning of Rule 13d-5(b)(1) under the Exchange Act; or 
 (c) the Company consolidates with, or merges with or into, another person or any person consolidates with, or merges with or into, the
Company, unless either: 
 (1) the persons that “beneficially owned” (as such term is used in Rule 13d-3 under the
Exchange Act), directly or indirectly, the shares of the Company’s Voting Stock immediately prior to such consolidation or merger, “beneficially own,” directly or indirectly, immediately after such consolidation or merger, shares of
the surviving or continuing corporation’s Voting Stock representing at least a majority of the total outstanding voting power of all outstanding classes of the Voting Stock of the surviving or continuing corporation in substantially the same
proportion as such ownership immediately prior to such consolidation or merger; or 
 (2) at least ninety percent (90%) of
the consideration (other than cash payments for fractional shares or pursuant to statutory appraisal 
  

 -32- 

 rights) in such consolidation or merger consists of common stock and any associated rights traded on a
U.S. national securities exchange or quoted on the Nasdaq National Market (or which will be so traded or quoted when issued or exchanged in connection with such consolidation or merger), and, as a result of such consolidation or merger, the
Securities become convertible solely (except as to any cash payments for the Principal Return, and cash in lieu of fractional shares, due upon conversion) into such common stock and associated rights (such a consolidation or merger that satisfies
the conditions set forth in this clause (2), a “Listed Stock Business Combination”); or 
 (d) the
following persons cease for any reason to constitute a majority of the Company’s Board of Directors: 
 (1) individuals
who on the Issue Date constituted the Company’s Board of Directors; and 
 (2) any new directors whose election to the
Company’s Board of Directors or whose nomination for election by the Company’s stockholders was approved by at least a majority of the directors of the Company then still in office either who were directors of the Company on the Issue Date
or whose election or nomination for election was previously so approved; or 
 (e) the Company is liquidated or dissolved or
the holders of the Company’s Capital Stock approve any plan or proposal for the liquidation or dissolution of the Company. 
 (ii) A “Termination of Trading” shall be deemed to occur if the Common Stock of the Company (or other common stock into which the Securities are then convertible) is neither listed for trading on a U.S. national securities
exchange nor approved for trading on an established automated over-the-counter trading market in the United States. 
 3.11
CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION. 
 In connection with a Redemption of Securities, the Company may arrange, in lieu of Redemption, for the purchase and conversion of any Securities called for Redemption by an agreement with one or more investment banks or other purchasers to
purchase all or a portion of such Securities by paying, on or before 11:00 A.M., New York City time on the Redemption Date, to the Paying Agent in trust for the Holders whose Securities are to be so purchased, an amount of money, in funds
immediately available on the Redemption Date, that, together with any amounts deposited with the Paying Agent by the Company for Redemption of such Securities, is not less than the aggregate Redemption Price, together with accrued and unpaid
interest, if any, to, but excluding, the Redemption Date, of such Securities. Notwithstanding anything to the contrary contained in this Article III, the obligation of the Company to pay the Redemption Price of such Securities, including all
accrued interest, if any, shall be deemed to be 
  

 -33- 

 satisfied and discharged to the extent such amount is so paid by such purchasers, but no such agreement shall relieve the
Company of its obligation to pay such Redemption Price or such accrued and unpaid interest, if any. If such an agreement is entered into, any Securities not duly surrendered for conversion by the Holders thereof may, at the option of the Company, be
deemed, to the fullest extent permitted by law, acquired by such purchasers from such Holders and (notwithstanding anything to the contrary contained in Article X) surrendered by such purchasers for conversion, all as of immediately prior to
the close of business on the Redemption Date, subject to payment of the above amount as aforesaid. The Paying Agent shall hold and pay to the Holders whose Securities are selected for Redemption any such amount paid to it for purchase and conversion
in the same manner as it would moneys deposited with it by the Company for the Redemption of Securities. Without the prior written consent of the Trustee, the Securities Agent and the Paying Agent, no arrangement between the Company and such
purchasers for the purchase and conversion of any Securities shall increase or otherwise affect any of the powers, duties, rights, immunities, responsibilities or obligations of the Trustee, the Securities Agent or the Paying Agent as set forth in
this Indenture, and the Company agrees to indemnify the Trustee, the Securities Agent and the Paying Agent from, and hold them harmless against, any and all loss, liability or expense arising out of or in connection with any such arrangement for the
purchase and conversion of any Securities between the Company and such purchasers, including the costs and expenses (including counsel fees and expenses) incurred by the Trustee, the Securities Agent or the Paying Agent in the defense of any claim
or liability arising out of or in connection with the exercise or performance of any of their powers, duties, responsibilities or obligations under this Indenture except to the extent arising from their bad faith, willful misconduct or negligence.

 IV. COVENANTS 
 4.01
PAYMENT OF SECURITIES. 
 The Company shall pay all amounts due with respect to the
Securities on the dates and in the manner provided in the Securities and this Indenture. All such amounts shall be considered paid on the date due if the Paying Agent holds (or, if the Company is acting as Paying Agent, the Company has segregated
and holds in trust in accordance with Section 2.04) on that date money sufficient to pay the amount then due with respect to the Securities (unless there shall be a Default in the payment of such amounts to the respective Holder(s)). 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
Security that is in global form, by wire transfer of immediately available funds to the account designated by the Depositary or its nominee; (B) in the case of a Security that is held, other than global form, by a Holder of more than five
million dollars ($5,000,000) in aggregate principal amount of Securities, by wire transfer of immediately available funds to the account specified 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; and (C) in the case of a Security that is held, other than global form, by a Holder of five million dollars ($5,000,000) or less in aggregate principal amount of Securities, by mailing a
check to the address of such Holder set forth in the register of the Registrar. 
  

 -34- 

 The Company shall pay, in cash, interest on any overdue amount (including, to the extent permitted by
applicable law, overdue interest) at the rate borne by the Securities. 
 4.02 MAINTENANCE OF OFFICE
OR AGENCY. 
 The Company will maintain, or cause to be maintained, in the Borough of Manhattan, the City of
New York, an office or agency (which may be an office of the Securities Agent or an affiliate of the Securities Agent, Registrar or co-Registrar) where Securities may be surrendered for registration of transfer or exchange, payment or conversion.
The Company will give prompt written notice to the Trustee and the Securities Agent of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain, or fail to cause to maintain, any such
required office or agency or shall fail to furnish the Trustee and the Securities Agent with the address thereof, such presentations and surrenders may be made or served at the applicable Corporate Trust Office of the Securities Agent. The Company
will maintain, or cause to be maintained, in the Borough of Manhattan, the City of New York, an office or agency where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served, provided that such
office or agency may instead be at the principal office of the Company located in the United States. 
 The Company may also from time to
time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, the City of New York for such purposes. The Company will give prompt written notice to the Trustee and the Securities
Agent of any such designation or rescission and of any change in the location of any such other office or agency. 
 The Company hereby
designates the applicable Corporate Trust Office of the Securities Agent as an agency of the Company in accordance with Section 2.03. 
 4.03 RULE 144A INFORMATION AND ANNUAL REPORTS. 
 (A) At any time when the Company is not subject to, or is in violation of, Sections 13 or 15(d) of the Exchange Act, the Company shall promptly provide to the Securities Agent and shall, upon request, provide to any Holder, beneficial owner
or prospective purchaser of Securities or shares of Common Stock issued upon conversion of any Securities, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Securities or
shares of Common Stock pursuant to Rule 144A; provided, however, that the Company shall not be obligated to provide such information if none of the outstanding Securities constitute “restricted securities” within the meaning
of Rule 144(a)(3) under the Securities Act. The Company shall take such further action as any Holder or beneficial holder of such Securities or shares of Common Stock may reasonably request in writing to the extent required from time to time to
enable such Holder or beneficial holder to sell its Securities or shares of Common Stock in accordance with Rule 144A, as such rule may be amended from time to time. 
  

 -35- 

 (B) The Company shall deliver to the Trustee and the Securities Agent, no later than the time such report
is required to be filed with the SEC pursuant to the Exchange Act, a copy of each report the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act; provided, however, that the Company shall not be
required to deliver to the Trustee or the Securities Agent any material for which the Company has sought and received confidential treatment by the SEC; provided further, each such report will be deemed to be so delivered to the Trustee and
the Securities Agent if the Company files such report with the SEC through the SEC’s EDGAR database no later than the time such report is required to be filed with the SEC pursuant to the Exchange Act. In the event the Company is at any time no
longer subject to the reporting requirements of Section 13 or Section 15(d) of the Exchange Act, the Company shall continue to provide the Trustee and the Securities Agent and each Holder, within thirty (30) calendar days after the
date the Company would have been required to file such reports with the SEC, annual and quarterly consolidated financial statements substantially equivalent to financial statements that would have been included in reports filed with the SEC if the
Company were subject to the reporting requirements of Section 13 or Section 15(d) of the Exchange Act, including, with respect to annual information only, a report thereon by the Company’s certified independent public accountants as
such would be required in such reports filed with the SEC and, in each case, together with a management’s discussion and analysis of financial condition and results of operations which would be so required. The Company also shall comply with
the other provisions of TIA § 314(a). 
 4.04 COMPLIANCE CERTIFICATE. 
 The Company shall deliver to the Trustee, within ninety (90) calendar days after the end of each fiscal year of the Company, or, if earlier, by the
date the Company is, or would be, required to file with the SEC the Company’s annual report (whether on Form 10-K under the Exchange Act or another appropriate form) for such fiscal year, certificate of two (2) or more Officers, stating
whether or not the signatories to such certificate have actual knowledge of any Default or Event of Default by the Company in performing any of its obligations under this Indenture or the Securities. If such signatories do know of any such Default
or Event of Default, then such certificate shall describe the Default or Event of Default and its status. 
 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; and the Company (in each case, 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. 
 4.06 CORPORATE EXISTENCE. 
 Subject to Article V, the
Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the corporate existence of 
  

 -36- 

 each of its Subsidiaries, in accordance with the respective organizational documents of the Company and of each
Subsidiary, and the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries; provided, however, that the Company shall not be required to preserve any such right, license or franchise, or the
corporate existence of any Subsidiary, if in the good faith judgment of the Board of Directors (i) such preservation or existence is not material to the conduct of business of the Company and (ii) the loss of such right, license or
franchise or the dissolution of such Subsidiary does not have a material adverse impact on the Holders. 
 4.07 NOTICE
OF DEFAULT. 
 Upon the Company becoming aware of the occurrence of any Default or Event of Default, the
Company shall give prompt written notice of such Default or Event of Default, and any remedial action proposed to be taken, to the Trustee and the Securities Agent. 
 4.08 FURTHER INSTRUMENTS AND ACTS. 
 Upon request of the Trustee or the Securities Agent, the Company shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this
Indenture. 
 V. SUCCESSORS 
 5.01 WHEN COMPANY MAY MERGE, ETC. 
 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 property or assets of the Company to, another person, whether in a single transaction or series of
related transactions, unless (i) such other person is a corporation organized and existing under the laws of the United States, any State thereof or the District of Columbia; (ii) such person assumes by supplemental indenture all the
obligations of the Company under the Securities and this Indenture; and (iii) immediately after giving effect to such transaction or series of transactions, no Default or Event of Default shall exist. 
 The Company shall deliver to the Trustee and the Securities Agent prior to the consummation of the proposed transaction an Officer’s Certificate to
the foregoing effect and an Opinion of Counsel (which may rely upon such Officer’s Certificate as to the absence of Defaults and Events of Default) stating that the proposed transaction and such supplemental indenture will, upon consummation of
the proposed transaction, comply with this Indenture. 
 5.02 SUCCESSOR SUBSTITUTED. 
 Upon any consolidation, merger or any sale, transfer, lease, conveyance or other disposition of all or substantially all of the property or assets of the
Company, the successor person formed by such consolidation or into which the Company is merged or to which such sale, transfer, lease, conveyance or other disposition is made shall succeed to, and, except in the case of a lease, be substituted for,
and may exercise every right and power of, and shall assume 
  

 -37- 

 every duty and obligation of, the Company under this Indenture with the same effect as if such successor had been named
as the Company herein. When the successor assumes all obligations of the Company hereunder, except in the case of a lease, all obligations of the predecessor shall terminate. 
 VI. DEFAULTS AND REMEDIES 
 6.01 EVENTS OF
DEFAULT. 
 An “Event of Default” occurs if:

become due and payable and such default is not cured or waived, or such acceleration is not rescinded, within sixty (60) days after notice to the Company by the Trustee or to the Company and the Trustee by Holders of at least twenty five
percent (25%) in the aggregate principal amount of the Securities then outstanding, each in accordance with this Indenture; 
 (vii) the Company or any of its Subsidiaries fails, within sixty (60) days, to pay, bond or otherwise discharge any judgments or orders for the payment of money the total uninsured amount of which for the Company or any of its
Subsidiaries exceeds fifty million dollars ($50,000,000), which are not stayed on appeal; 
  

 -38- 

 (viii) the Company or any of its Significant Subsidiaries or any group of Subsidiaries
that in the aggregate would constitute a Significant Subsidiary of the Company, pursuant to, or within the meaning of, any Bankruptcy Law, insolvency law, or other similar law now or hereafter in effect or otherwise, either: 
 (A) commences a voluntary case, 
 (B) consents to the entry of an order for relief against it in an involuntary case,

similar U.S. Federal or State law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law. 
  

 -39- 

 A Default under clause (v) above is not an Event of Default until (I) the Trustee
notifies the Company, 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 (II) 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. 
 6.02 ACCELERATION. 
 If an Event
of Default (excluding an Event of Default specified in Section 6.01(viii) or (ix) with respect to the Company (but including an Event of Default specified in Section 6.01(viii) or (ix) solely with
respect to a Significant Subsidiary of the Company or any group of Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company)) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at
least twenty five percent (25%) in aggregate principal amount of the Securities then outstanding by notice to the Company and the Trustee, may declare the Securities to be immediately due and payable in full. Upon such declaration, the
principal of, and any accrued and unpaid interest (including any Contingent Interest and additional interest) on, all Securities shall be due and payable immediately. If an Event of Default specified in Section 6.01(viii) or
(ix) with respect to the Company (excluding, for purposes of this sentence, an Event of Default specified in Section 6.01(viii) or (ix) solely with respect to a Significant Subsidiary of the Company or any group
of Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company) occurs, the principal of, and accrued and unpaid interest (including any Contingent Interest and additional interest) on, all the Securities shall
ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. 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 (A) the rescission would not conflict with any order or decree, (B) all existing Events of Default, except the nonpayment of principal or interest (including
Contingent Interest and additional interest) that has become due solely because of the acceleration, have been cured or waived and (C) all amounts due to the Trustee and the Securities Agent under Section 7.07 have been paid.

 6.03 OTHER REMEDIES. 
 Notwithstanding any other provision of this Indenture, if an Event of Default occurs and is continuing, and a Responsible Officer of the Trustee has actual knowledge of such Event of Default, 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.

  

 -40- 

 6.04 WAIVER OF PAST DEFAULTS. 
 Subject to Sections 6.07 and 9.02, the Holders of a majority in aggregate principal amount of the Securities then outstanding may, by notice
to the Trustee, waive any past Default or Event of Default and its consequences, other than (A) a Default or Event of Default in the payment of the principal of, or premium, if any, or interest, Contingent Interest or additional interest on,
any Security, or in the payment of the Redemption Price, the Option Purchase Price or the Fundamental Change Repurchase Price (or accrued and unpaid interest, if any, payable as herein provided, upon Redemption, Purchase at Holder’s Option or
Repurchase Upon Fundamental Change), (B) a Default or Event of Default arising from a failure by the Company to convert any Securities in accordance with this Indenture or (C) any Default or Event of Default in respect of any provision of
this Indenture or the Securities which, under Section 9.02, cannot be modified or amended without the consent of the Holder of each outstanding Security affected. When a Default or an Event of Default is waived, it is cured and ceases to
exist for all purposes under this Indenture. This Section 6.04 shall be in lieu of TIA § 316(a)(1)(B), and, as permitted by the TIA, TIA § 316(a)(1)(B) is hereby expressly excluded from this Indenture. 
 6.05 CONTROL BY MAJORITY. 
 The Holders of a majority in aggregate principal amount of the Securities then outstanding may 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. 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 reasonably satisfactory to it; provided, that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. This Section 6.05 shall be in lieu of TIA
§ 316(a)(1)(A), and, as permitted by the TIA, TIA § 316(a)(1)(A) is hereby expressly excluded from this Indenture. 
 6.06
LIMITATION ON SUITS. 
 Except as provided in Section 6.07, a Securityholder may
not institute any proceeding under this Indenture, or for the appointment of a receiver or a trustee, or for any other remedy under this Indenture unless: 
 (i) the Holder gives to the Trustee written notice of a continuing Event of Default; 
 (ii)
the Holders of at least twenty five percent (25%) in aggregate principal amount of the Securities then outstanding make a written request to the Trustee to pursue the remedy; 
 (iii) such Holder or Holders offer and, if requested, provide to the Trustee indemnity reasonably satisfactory to the Trustee against any
loss, liability or expense to or of the Trustee in connection with pursuing such remedy;

 A Securityholder
may not use this Indenture to prejudice the rights of another Securityholder or to obtain a preference or priority over another Securityholder.

 6.08 COLLECTION SUIT BY TRUSTEE.

 If an Event of Default specified in Section 6.01(i) or (ii) occurs and is continuing, the Trustee may recover

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.

 7.01 DUTIES OF
TRUSTEE AND THE SECURITIES AGENT. 
 (A) If an Event of Default
has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances
in the conduct of his or her own affairs. 
 (B) The Trustee, except during the continuance of an Event of Default, and the Securities Agent:

 (i) need perform only those duties that are specifically set forth in this Indenture and no implied covenants or

 -43- 

 (ii) in the absence of bad faith, willful misconduct or negligence on its part, may
conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee or the Securities Agent, as the case may be, and conforming to the requirements of
this Indenture; but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee or the Securities Agent, the Trustee or the Securities Agent, as the case may be, shall

willful misconduct, except that:

made in good faith by a Responsible Officer thereof, unless it is proved that the Trustee or the Securities Agent, as the case may be, was negligent in ascertaining the pertinent facts; and 
 (ii) the Trustee shall be not liable with respect to any action it takes or omits to take in good faith in accordance with a direction
received by it pursuant to Section 6.05.

liable for interest on any money received by it except as the Trustee or the Securities Agent, as the case may be, may agree in writing with the Company. Money held in trust by the Trustee or the Securities Agent shall be segregated from other funds
as directed in writing by the Company or as required by law and shall be invested by the Trustee or the Securities Agent, as applicable, pursuant to the written instructions of the Company reasonably satisfactory to the Trustee or the Securities
Agent, as applicable. 
 7.02 RIGHTS OF TRUSTEE AND THE
SECURITIES AGENT. 
 (A) Subject to Section 7.01, each of the Trustee and the Securities Agent
may conclusively rely on any document believed by it to be genuine and to have been signed or presented by the proper person. Neither the Trustee nor the Securities Agent need investigate any fact or matter stated in the document; if, however, the

agent or attorney upon reasonable prior notice. 
 (B) Before the Trustee or the Securities Agent acts or refrains from acting, it may
require an Officer’s Certificate and/or an Opinion of Counsel. Neither the Trustee nor the Securities Agent shall be liable for any action it takes or omits to take in good faith in reliance on such Officer’s Certificate or Opinion of

inquire as to the performance of the Company with respect to the covenants contained in Article IV. In addition, neither the Trustee nor the Securities Agent shall be deemed to have knowledge of a Default, Event of Default, Fundamental
Change, Make-Whole Fundamental Change or Public Acquirer Fundamental Change except (i) with respect to the Securities Agent any Default or Event of Default occurring pursuant to Sections 6.01(i) or (ii) (the Securities Agent
agrees to promptly notify the Trustee of such a Default or Event of Default upon a Responsible Officer of the Securities Agent acquiring actual knowledge of such Default or Event of Default) or a Fundamental Change, Make-Whole Fundamental Change or
Public Acquirer Fundamental Change or (ii) any Default, Event of Default, Fundamental Change, Make-Whole Fundamental Change or Public Acquirer Fundamental Change of which a Responsible Officer of the Trustee or the Securities Agent, as the case

conclusively assume that there is no Default, Event of Default, Fundamental Change, Make-Whole Fundamental Change or Public Acquirer Fundamental Change. Delivery of reports, information and documents to the Trustee or the Securities Agent under
Article IV (other than Sections 4.04 and 4.07) is for informational purposes only and the receipt by the Trustee or the Securities Agent of the foregoing shall not constitute constructive notice of any information contained
therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which each of the Trustee and the Securities Agent is entitled to rely on Officer’s Certificates).

 (H) Subject to Section 7.01(A), neither the Trustee nor the Securities Agent shall be under any obligation to exercise any of
the rights or powers vested by this Indenture at the request or direction of any of the Holders pursuant to this Indenture unless such Holders shall have offered to the Trustee or the Securities Agent, as applicable, security or indemnity

  

 -45- 

 reasonably satisfactory to the Trustee or the Securities Agent, as applicable, against the costs, expenses and
liabilities which might be incurred by it in compliance with such request or direction.

request that the Company deliver an Officer’s Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officer’s Certificate may be
signed by any person authorized to sign an Officer’s Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded. 
 (K) Neither the Trustee nor the Securities Agent shall be required to expend or risk its own funds or otherwise incur financial liability for the
performance of any of its duties hereunder or the exercise of any of its rights or powers if there is reasonable ground for believing that the repayment of such funds or reasonably adequate indemnity against such risk or liability is not assured to
it. 
 (L) Neither the Trustee nor the Securities Agent shall have any duty (i) to see to any recording, filing or depositing of this
Indenture or any Indenture referred to herein or any financing statement or continuation statement evidencing a security interest, or to see to the maintenance of any such recording or filing or depositing or to any rerecording, refiling or
redepositing of any thereof or (ii) to see to any insurance. 
 (M) The rights of the Trustee and the Securities Agent to perform any
discretionary act enumerated in this Indenture shall not be construed as a duty, and neither the Trustee nor the Securities Agent shall be answerable other than for its negligence or willful misconduct in the performance of such act.

 7.05 NOTICE OF DEFAULTS. 
 If a Default or Event of Default occurs and is continuing as to which the Trustee has received notice pursuant to the provisions of this Indenture, or as
to which a Responsible Officer of the Trustee shall have actual knowledge, then the Trustee shall mail to each Holder a notice of the Default or Event of Default within thirty (30) days after receipt of such notice or after acquiring such
knowledge, as applicable, unless such Default or Event of Default has been cured or waived; provided, however, that, except in the case of a Default or Event of Default in payment of any amounts due with respect to any Security, the
Trustee may withhold such notice if, and so long as it in good faith determines that, withholding such notice is in the best interests of Holders. 
 7.06 REPORTS BY TRUSTEE TO HOLDERS. 
 Within sixty (60) days after each May 15, beginning with May 15, 2007, the Trustee shall mail to each Securityholder if required by TIA § 313(a) a brief report dated as of such May 15 that complies with TIA §

 A copy of each report at the time of its mailing to
Securityholders shall be mailed by first class mail to the Company and filed by the Trustee with the SEC and each stock exchange, if any, on which the Securities are listed. The Company shall promptly notify the Trustee of the listing or delisting
of the Securities on or from any stock exchange. 
 7.07 COMPENSATION AND INDEMNITY. 

The Company shall pay to the Trustee and the Securities Agent from time to time such compensation for their services as shall be agreed upon in
writing. Neither the Trustee’s nor the Securities Agent’s compensation shall be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee and the Securities Agent upon request for all
reasonable out-of-pocket expenses incurred by them pursuant to, and in accordance with, any provision hereof. Such expenses shall include the reasonable compensation and out-of-pocket expenses of the agents and counsel of the Trustee and the
Securities Agent. 
 The Company shall indemnify each of the Trustee and the Securities Agent against any and all loss, liability, damage,
claim or expense (including the reasonable fees and expenses of counsel and taxes other than those based upon the income of the Trustee or the Securities Agent) incurred by it in connection with the acceptance or administration of this trust and the
performance of its duties hereunder, including the reasonable costs and expenses of defending itself against any claim (whether asserted by the Company, any Holder or any other Person) or liability in connection with the exercise or performance of
any of its powers and duties hereunder. The Company need not pay any settlement made without its consent, which consent shall not be unreasonably withheld or delayed. Each of the Trustee and the Securities Agent shall notify the Company promptly of
any claim for which it may seek indemnification. The Company need not reimburse any expense or indemnify against any loss or liability incurred by the Trustee or the Securities Agent through the negligence, bad faith or willful misconduct of the
Trustee or the Securities Agent, as the case may be. 
  

 -47- 

 Notwithstanding anything herein to the contrary, to the extent permitted by the TIA, in no event shall
the Trustee or the Securities Agent be liable for special, indirect or consequential losses or damages of any kind whatsoever (including, without limitation, lost profits), even if the Trustee or the Securities Agent, as applicable, has been advised
of the likelihood of such losses or damages and regardless of the form of action. 
 To secure the Company’s payment obligations in this
Section 7.07, the Trustee and the Securities Agent shall have a lien prior to the Securities on all money or property held or collected by the Trustee or the Securities Agent, except that held in trust to pay amounts due on particular
Securities. 
 The indemnity obligations of the Company with respect to the Trustee and the Securities Agent provided for in this
Section 7.07 shall survive any resignation or removal of the Trustee or the Securities Agent, as applicable. 
 When the Trustee
or the Securities Agent incurs expenses or renders services after an Event of Default specified in Section 6.01(viii) or (ix) occurs, the expenses and the compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law. 
 7.08 REPLACEMENT OF TRUSTEE OR
THE SECURITIES AGENT. 
 A resignation or removal of the Trustee or the Securities Agent and
appointment of a successor Trustee or successor Securities Agent shall become effective only upon such successor’s acceptance of appointment as provided in this Section 7.08. 
 Each of the Trustee and the Securities Agent may resign by so notifying the Company in writing thirty (30) Business Days prior to such resignation.
The Holders of a majority in aggregate principal amount of the Securities then outstanding may remove the Trustee or the Securities Agent by so notifying the Trustee or the Securities Agent, as applicable, and the Company in writing and may appoint

 If a successor Trustee or successor Securities Agent, as applicable, does not take office within thirty (30) days after the retiring Trustee or retiring Securities Agent, as applicable, resigns or is removed, the retiring Trustee or
retiring Securities Agent, as applicable, may, at the Company’s expense, and the Company or the Holders of at least ten percent (10%) in aggregate principal amount of the outstanding Securities may, petition any court of competent
jurisdiction for the appointment of a successor Trustee or successor Securities Agent, as applicable. 
 If the Trustee or the Securities
Agent fails to comply with Section 7.10, the Company or any Holder may petition any court of competent jurisdiction for the removal of the Trustee or the Securities Agent, as applicable, and the appointment of a successor Trustee or
successor Securities Agent, as applicable. 
 Each successor Trustee or successor Securities Agent shall deliver a written acceptance of its
appointment to the retiring Trustee or retiring Securities Agent, as applicable, and to the Company. Thereupon, the resignation or removal of the retiring Trustee or the retiring Securities Agent, as applicable, shall become effective, and the
successor Trustee or successor Securities Agent, as applicable, shall have all the rights, powers and duties of the Trustee or the Securities Agent, as applicable, under this Indenture. The successor Trustee or successor Securities Agent, as
applicable, shall mail a notice of its succession to Securityholders. The retiring Trustee or retiring Securities Agent, as applicable, shall promptly transfer all property held by it as Trustee or Securities Agent, as applicable, to the successor
Trustee or successor Securities Agent, as applicable, subject to the lien provided for in Section 7.07. 
 7.09
SUCCESSOR TRUSTEE BY MERGER, ETC. 
 If the Trustee or the
Securities Agent consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee or successor

Securities because of the reinstatement of its obligations, then the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or Paying Agent. 
 IX. AMENDMENTS

 -51- 

 (v) to make provisions with respect to adjustments to the Conversion Rate as required by
this Indenture or to increase the Conversion Rate in accordance with this Indenture. 
 In addition, the Company, the Trustee and the
Securities Agent may enter into a supplemental indenture without the consent of Holders of the Securities to cure any ambiguity, defect, omission or inconsistency in this Indenture in a manner that does not, individually or in the aggregate with all
other modifications made or to be made to the Indenture, adversely affect the rights of any Holder in any material respect. 
 9.02
WITH CONSENT OF HOLDERS. 
 The Company, with the consent of the Trustee
and the Securities Agent, may amend or supplement this Indenture or the Securities without notice to any Securityholder but with the written consent of the Holders of at least a majority in aggregate principal amount of the outstanding Securities.
Subject to Sections 6.04 and 6.07, the Holders of a majority in aggregate principal amount of the outstanding Securities may, by notice to the Trustee, waive compliance by the Company with any provision of this Indenture or the Securities
without notice to any other Securityholder. Notwithstanding anything herein to the contrary, without the consent of each 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, Contingent Interest or additional interest on, any Security; 
 (b) reduce the principal amount of,
or any premium, interest, Contingent Interest or additional interest on, any Security; 
 (c) change the place, manner or
currency of payment of principal of, or any premium, interest, Contingent Interest or additional interest on, any Security; 
 (d) impair the right to institute suit for the enforcement of any payment on, or with respect to, or of the conversion of, any Security; 
 (e) modify, in a manner adverse to Holders, the provisions with respect to the right of Holders pursuant to Article III to require the Company to purchase Securities on an Option Purchase Date or to repurchase
Securities upon the occurrence of a Fundamental Change; 
 (f) modify the provisions of Section 2.18 in a manner
adverse to Holders; 
 (g) adversely affect the right of Holders to convert Securities in accordance with Article X;

  

 -52- 

 (h) reduce the percentage of the aggregate principal amount of the outstanding Securities
whose Holders must consent to a modification to or amendment of any provision of this Indenture or the Securities; 
 (i)
reduce the percentage of the aggregate principal amount of the outstanding Securities whose Holders must consent to a waiver of compliance with any provision of this Indenture or the Securities or a waiver of any Default or Event of Default; or

 (j) modify the provisions of this Indenture 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 consent of each affected Holder. 
 Promptly after an amendment, supplement or waiver under Section 9.01 or this Section 9.02 becomes effective, the Company shall mail, or cause to be mailed, to Securityholders a notice briefly describing such
amendment, supplement or waiver. Any failure of the Company to mail 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. 
 9.03 COMPLIANCE
WITH TRUST INDENTURE ACT. 
 Every amendment, waiver or supplement to this
Indenture or the Securities shall comply with the TIA as then in effect. 
 9.04 REVOCATION AND EFFECT
OF CONSENTS. 
 Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a
continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such
Holder or subsequent Holder may revoke the consent as to its Security or portion of a Security if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver
becomes effective in accordance with its terms and thereafter binds every Holder. 
 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, provided that notice of such amendment, supplement or waiver is reflected on a Security that evidences the same debt as the consenting Holder’s Security,
every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security. 
  

 -53- 

 Nothing in this Section 9.04 shall impair the Company’s rights pursuant
Section 9.01 to amend this Indenture or the Securities without the consent of any Securityholder in the manner set forth in, and permitted by, such Section 9.01. 
 9.05 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 Securities Agent shall authenticate a new Security that reflects the changed terms. 
 9.06 TRUSTEE AND
SECURITIES AGENT PROTECTED. 
 The Trustee and the Securities Agent shall sign any amendment,
supplemental indenture or waiver authorized pursuant to this Article IX; provided, however, that neither the Trustee nor the Securities Agent need sign any amendment, supplement or waiver authorized pursuant to this Article
IX that adversely affects the rights, duties, liabilities or immunities of the Trustee or the Securities Agent, as applicable. Each of the Trustee and the Securities Agent shall be entitled to receive and conclusively rely upon an Opinion of
Counsel as to legal matters and an Officer’s Certificate as to factual matters that any supplemental indenture, amendment or waiver is permitted or authorized pursuant to this Indenture. 
 9.07 EFFECT OF SUPPLEMENTAL INDENTURES. 
 Upon the due execution and delivery of any supplemental indenture in accordance with this Article IX, 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 Sections 9.02 and 9.04, every Holder of Securities shall be bound thereby. 
 X. CONVERSION 
 10.01
CONVERSION PRIVILEGE; RESTRICTIVE LEGENDS. 
 (A) Subject to the provisions
of Article III, the Securities shall be convertible into cash and, if applicable, shares of Common Stock in accordance with this Article X and as set forth below if any of the following conditions are satisfied: 
 (i) Conversion Based on Closing Sale Price of Common Stock. The Securities may be surrendered for conversion into cash and, if
applicable, shares of Common Stock on any Business Day of a calendar quarter after the calendar quarter ending September 30, 2006, if the Closing Sale Price for each of twenty (20) or more Trading Days in a period of thirty
(30) consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar quarter exceeds one hundred and twenty percent (120%) of the Conversion Price in effect on the last Trading Day of the immediately preceding
calendar quarter. Solely for purposes of 
  

 -54- 

 determining whether the Securities shall have become convertible pursuant to this
Section 10.01(A)(i), the Board of Directors shall, in its good faith determination, which shall be described in a Board Resolution, make appropriate adjustments to the Closing Sale Prices and/or such Conversion Price used to determine
whether the Securities shall have become convertible pursuant to this Section 10.01(A)(i) to account for any adjustments to the Conversion Rate which shall have become effective, or any event requiring an adjustment to the Conversion
Rate where the Ex Date of such event occurs, during the period of thirty (30) consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar quarter. 
 (ii) Conversion Upon Satisfaction of Trading Price Condition. The Securities may be surrendered for conversion into cash and, if
applicable, shares of Common Stock during the five (5) consecutive Business Days immediately after any five (5) consecutive Trading Day period (such five (5) consecutive Trading Day period, the “Note Measurement
Period”) in which the average Trading Price per $1,000 principal amount of the Securities was equal to or less than ninety seven percent (97%) of the average Conversion Value (as defined below) during the Note Measurement Period (such
condition, the “Trading Price Condition”). The Bid Solicitation Agent shall not have any obligation to determine the Trading Price unless the Company has requested such determination in writing, and the Company shall have no
obligation to make such request unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of the Securities would be equal to or less than ninety seven percent (97%) of the product of the
Closing Sale Price and the Conversion Rate. Upon receipt of such evidence, the Company shall instruct the Bid Solicitation Agent in writing to determine the Trading Price per $1,000 principal amount of the Securities for each of the five
(5) successive Trading Days immediately after the Company receives such evidence and on each Trading Day thereafter until the first Trading Day on which the Trading Price Condition is no longer satisfied. For purposes of this paragraph, the
“Conversion Value” per $1,000 principal amount of Securities, on a given Trading Day, means the product of the Closing Sale Price on such Trading Day and the Conversion Rate in effect on such Trading Day. 
 (iii) Conversion Based on Redemption. A Security, or portion of a Security, which has been called for Redemption pursuant to
paragraph 6 of the Securities may be surrendered for conversion into cash and, if applicable, shares of Common Stock; provided, however, that such Security or portion thereof may be surrendered for conversion pursuant to this
paragraph only until the close of business on the third (3rd) Business Day immediately preceding the Redemption Date. 
 (iv) Conversion Upon Certain Distributions. If the Company takes any action, or becomes aware of any event, that would require an adjustment to the Conversion Rate pursuant to Sections 10.05(b), 10.05(c),
10.05(d) or 10.05(e), the Securities may be surrendered for conversion into cash and, if applicable, shares of Common Stock beginning on the date the Company mails the notice to the Holders as provided in Section 10.10 (or,
if earlier, the date the Company is required to mail such notice) and at any time thereafter until the close of business on the Business Day immediately preceding the Ex Date (as defined in Section 10.05(g)) of the applicable transaction or
until the Company announces that such transaction will not take place. 
  

 -55- 

 (v) Conversion Upon Occurrence of Certain Corporate Transactions. If either:

 (a) a Fundamental Change or a Make-Whole Fundamental Change occurs; or 
 (b) the Company is a party to a consolidation, merger or binding share exchange 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, 
 then, in each case, the Securities
may be surrendered for conversion into cash and, if applicable, shares of Common Stock at any time during the period that begins on, and includes, the date that is thirty (30) calendar days prior to the date originally announced by the Company
as the anticipated effective date of such transaction (which anticipated effective date the Company shall disclose, in good faith, in the written notice, public announcement and publication referred to in Section 10.01(C)) and ends on,
and includes, the date that is thirty (30) calendar days after the actual effective date of such transaction; provided, however, that if such transaction is a Make-Whole Fundamental Change, then the Securities may also be
surrendered for conversion into cash and, if applicable, shares of Common Stock at any time during the Make-Whole Conversion Period applicable to such Make-Whole Fundamental Change; provided, further, that if such transaction is a
Fundamental Change, then the Securities may also be surrendered for conversion into cash and, if applicable, shares of Common Stock at any time until, and including, the Fundamental Change Repurchase Date applicable to such Fundamental Change.

 (vi) Conversion on or after June 1, 2024 and at any time from November 1, 2011 to December 1, 2011.
The Securities may be surrendered for conversion into cash and, if applicable, shares of Common Stock at any time on or after June 1, 2024 and at any time from, and including, November 1, 2011 to, and including, December 1, 2011.

 (B) The initial Conversion Rate shall be 11.0485 shares of Common Stock per $1,000 principal amount of Securities. The Conversion Rate
shall be subject to adjustment in accordance with Sections 10.05 through 10.14. 
 (C) Whenever any event described in
Section 10.01 shall occur which shall cause the Securities to become convertible as provided in this Article X, the Company shall promptly deliver, in accordance with Section 12.02, written notice of the convertibility
of the Securities to the Trustee, the Securities Agent, the Conversion Agent and each Holder and shall, as soon practicable, but in no event later than the open of business on the first Business Day following the date the Securities shall become
convertible as provided in this Article X as a result of such event, publicly announce, through a reputable national newswire service, and publish on the 
 Company’s website, that the Securities have become convertible. Such written notice, public announcement and publication shall include: 
 (i) a description of such event; 
  

 -56- 

 (ii) a description of the periods during which the Securities shall be convertible as
provided in this Article X as a result of such event; 
 (iii) the anticipated effective date of such event, if
applicable; and 
 (iv) the procedures Holders must follow to convert their notes in accordance with this Article X,
including the name and address of the Conversion Agent. 
 (D) 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. Provisions of this Indenture that apply to conversion of all of a Security also apply to conversion of a portion of such Security. 
 (E) Any shares of Common Stock that are issued upon conversion of a Security shall bear the Private Placement Legend until the earlier of the second
anniversary of the later of the Issue Date and the last date on which the Company or any Affiliate was the owner of such shares or the Security (or any predecessor security) from which such shares were converted (or such shorter period of time as
permitted by Rule 144(k) under the Securities Act or any successor provision thereunder) (or such longer period of time as may be required under the Securities Act or applicable state securities laws, as set forth in an Opinion of Counsel, unless
otherwise agreed by the Company and the Holder thereof). 
 10.02 CONVERSION PROCEDURE AND
PAYMENT UPON CONVERSION. 
 (A) To convert a Security, a Holder must satisfy the requirements
of paragraph 10 of the Securities. Upon conversion of a Holder’s Security, the Company shall deliver, through the Conversion Agent, the following to such Holder: 
 (i) an amount (the “Principal Return”) in cash equal to the sum of the Daily Principal Return for each Trading Day in the
Cash Settlement Averaging Period for such conversion; and 
 (ii) if the sum of the Daily Net Shares for each Trading Day in
the Cash Settlement Averaging Period for such conversion is greater than or equal to one (1), a certificate for a number of shares of Common Stock (the “Net Shares”) equal to such sum; provided, however, that the
Company shall not issue fractional shares of Common Stock and shall instead deliver cash (in addition to any other consideration payable upon such conversion) in an amount equal to the value of such fraction computed on the basis of the Closing Sale
Price per share of Common Stock on the Conversion Date of such conversion. 
  

 -57- 

 The Company shall deliver such Principal Return and, if applicable, such Net Shares as soon as
practicable following the date (the “Conversion Date”) on which such Holder satisfies all the requirements for such conversion specified in paragraph 10 of the Securities, but in no event more than three (3) Business
Days after the last Trading Day in the Cash Settlement Averaging Period applicable to such conversion; provided, however, that any Make-Whole Consideration payable pursuant to Section 10.14 shall be delivered by the Company
within the time period specified in Section 10.14. 
 (B) “Cash Settlement Averaging Period” shall mean, with
respect to a Security that is tendered for conversion in accordance with this Article X, the twenty (20) consecutive Trading-Day period that begins on, and includes, the second (2nd) Trading Day after the day such Security is
tendered for such conversion. 
 “Daily Principal Return” shall mean, with respect to a Trading Day, the lesser of fifty
dollars ($50) and the Daily Conversion Value for such Trading Day. 
 “Daily Conversion Value” shall mean, with respect to a
Trading Day, one-twentieth (1/20th) of the product of (i) the Conversion Rate in effect on such Trading Day and (ii) the Closing Sale Price per share of Common Stock on such Trading Day. 
 “Daily Net Shares” shall mean, with respect to a Trading Day, an amount equal to the following: (i) if the Daily Conversion Value
for such Trading Day is equal to or lesser than fifty dollars ($50), then the Daily Net Shares with respect to such Trading Day shall mean an amount equal to zero (0); and (ii) if the Daily Conversion Value for such Trading Day exceeds fifty
dollars ($50), then the Daily Net Shares with respect to such Trading Day shall mean a fraction (a) whose numerator is the excess of such Daily Conversion Value over fifty dollars ($50) and (b) whose denominator is the Closing Sale Price
per share of Common Stock on such Trading Day. 
 (C) On and after the Conversion Date of a Security, the person in whose name any
certificate representing Net Shares, if any, is to be registered shall be treated as a stockholder of record of the Company, and all rights of the Holder of such Security shall terminate, other than the right to receive the consideration deliverable
upon conversion of such Security as provided herein. A Holder of Securities is not entitled, as such, to any rights of a holder of Common Stock until such Holder has converted its Securities into shares of Common Stock (to the extent such Securities
are convertible into Shares of Common Stock) or is deemed to be a stockholder of record of the Company, as provided in this Section 10.02(C). 
 (D) Except as provided in the Securities or in this Article X, no payment or adjustment will be made for accrued interest, Contingent Interest or additional interest on a converted Security or for dividends on
any Common Stock issued on or prior to 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 and prior to the related interest payment date, then,
notwithstanding such conversion, the 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 
  

 -58- 

 Agent on behalf of the Company of an amount equal to the interest payable on such interest payment date on the portion 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 if such Security is called for Redemption
pursuant to Section 3.04 and paragraphs 6 and 7 of the Securities; provided further, that, if the Company shall have, prior to the Conversion Date with respect to a Security, defaulted in a payment of interest on such
Security, then in no event shall the Holder of such Security who surrenders such Security for conversion be required to pay such defaulted interest or the interest that shall have accrued on such defaulted interest pursuant to
Section 2.12 or otherwise (it being understood that nothing in this Section 10.02(D) shall affect the Company’s obligations under Section 2.12). 
 (E) If a Holder converts more than one Security at the same time, the number of full shares of Common Stock issuable upon such conversion, if any, shall
be based on the total principal amount of all Securities converted. 
 (F) Upon surrender of a Security that is converted in part, the
Securities Agent shall authenticate for the Holder a new Security equal in principal amount to the unconverted portion of the Security surrendered. 
 (G) If the last day on which a Security may be converted is a Legal Holiday in a place where a Conversion Agent is located, the Security may be surrendered to that Conversion Agent on the next succeeding day that is not a Legal Holiday.

 10.03 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
shares of Common Stock upon the conversion. However, such Holder shall pay any such tax or duty which is due because such shares are issued in a name other than such Holder’s name. The Conversion Agent may refuse to deliver a certificate
representing the shares of Common Stock to be issued 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 such shares are to be issued in a name other than
such Holder’s name. Nothing herein shall preclude any tax withholding required by law or regulation. 
 10.04 COMPANY
TO PROVIDE STOCK. 
 The Company shall at all times reserve out of its authorized but
unissued Common Stock or Common Stock held in its treasury enough shares of Common Stock to permit the conversion, in accordance herewith, of all of the Securities. The shares of Common Stock, if any, due upon conversion of a Global Security shall
be delivered by the Company in accordance with the Depositary’s customary practices. 
 All shares of Common Stock which may be 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. 
  

 -59- 

 The Company shall comply with all securities laws regulating the offer and delivery of shares of 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. 
 10.05 ADJUSTMENT OF CONVERSION RATE. 
 The Conversion Rate shall be subject to adjustment from time to time as follows: 
 (a) In case the Company shall
(1) pay a dividend in shares of Common Stock to all holders of Common Stock, (2) make a distribution in shares of Common Stock to all holders of Common Stock, (3) subdivide the outstanding shares of Common Stock into a greater number
of shares of Common Stock or (4) combine the outstanding shares of Common Stock into a smaller number of shares of Common Stock, the Conversion Rate shall be adjusted by multiplying the Conversion Rate in effect immediately prior to close of
business on the record date or effective date, as applicable, of such dividend, distribution, subdivision or combination by the number of shares of Common Stock which a person who owns only one share of Common Stock immediately before the record
date or effective date, as applicable, of such dividend, distribution, subdivision or combination and who is entitled to participate in such dividend, distribution, subdivision or combination would own immediately after giving effect to such
dividend, distribution, subdivision or combination (without giving effect to any arrangement pursuant to such dividend, distribution, subdivision or combination not to issue fractional shares of Common Stock). Any adjustment made pursuant to this
Section 10.05(a) shall become effective immediately after the record date in the case of a dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision or combination. 

(b) In case the Company shall issue rights or warrants to all or substantially all holders of Common Stock, entitling them, for a
period expiring not more than sixty (60) days immediately following the record date for the determination of holders of Common Stock entitled to receive such rights or warrants, to subscribe for or purchase shares of Common Stock (or securities
convertible into or exchangeable or exercisable for Common Stock), at a price per share (or having a conversion, exchange or exercise price per share) that is less than the current market price (as determined pursuant to
Section 10.05(g)) per share of Common Stock on the record date for the determination of holders of Common Stock entitled to receive such rights or warrants, the Conversion Rate shall be increased by multiplying the Conversion Rate
in effect immediately prior to such record date by a fraction of which (A) the numerator shall be the sum of (I) the number of shares of Common Stock outstanding at the close of business on such record date and (II) the aggregate number of
shares (the “Underlying Shares”) of Common Stock underlying all such issued rights or warrants (whether by exercise, conversion, exchange or otherwise), and (B) the denominator shall be the sum of (I) number of shares of
Common Stock outstanding at the close of business on such record date and (II) the number of shares of Common Stock which 
  

 -60- 

 the aggregate exercise, conversion, exchange or other price at which the Underlying Shares may be
subscribed for or purchased pursuant to such rights or warrants would purchase at such current market price per share of Common Stock; provided, however, no adjustment shall be made pursuant to this Section 10.05(b) solely
by reason of a distribution of rights pursuant to a stockholders’ rights plan, provided the Company has complied with the provisions of Section 10.13 with respect to such stockholders’ rights plan and distribution. Such
increase shall become effective immediately prior to the opening of business on the day following such record date. In no event shall the Conversion Rate be decreased pursuant to this Section 10.05(b). 
 (c) In case the Company shall dividend or distribute to all or substantially all holders of Common Stock shares of Capital Stock of the
Company or any existing or future Subsidiary (other than Common Stock), evidences of Indebtedness or other assets (other than dividends or distributions requiring an adjustment to the Conversion Rate in accordance with Sections 10.05(d) or
10.05(e)), or shall dividend or distribute to all or substantially all holders of Common Stock rights or warrants to subscribe for or purchase securities (other than dividends or distributions of rights or warrants requiring an adjustment to the
Conversion Rate in accordance with Section 10.05(b)), then in each such case the Conversion Rate shall be increased by multiplying the Conversion Rate in effect immediately prior to the close of business on the record date for the
determination of stockholders entitled to such dividend or distribution by a fraction of which (A) the numerator shall be the current market price per share of Common Stock (as determined pursuant to Section 10.05(g)) on such record
date and (B) the denominator shall be an amount equal to (I) such current market price per share of Common Stock less (II) the fair market value (as determined in good faith by the Board of Directors, whose determination shall be
conclusive and described in a Board Resolution), on such record date, of the portion of the shares of Capital Stock, evidences of Indebtedness, assets, rights and warrants to be dividended or distributed applicable to one share of Common Stock, such
increase to become effective immediately prior to the opening of business on the day following such record date; provided, however, that if such denominator is equal to or less than zero, then, in lieu of the foregoing adjustment to
the Conversion Rate, adequate provision shall be made so that each Holder shall have the right to receive upon conversion of its Securities, in addition to any consideration otherwise payable as herein provided upon such conversion, an amount, per
$1,000 principal amount of such Securities, of shares of Capital Stock, evidences of Indebtedness, assets, rights and/or warrants that a person that owns, on such record date, a number of shares of Common Stock equal to the Conversion Rate in effect
at the close of business on such record date would have received as a result of such dividend or distribution. Notwithstanding the foregoing, in the event that the Company shall distribute rights or warrants (other than distributions of rights or
warrants requiring an adjustment to the Conversion Rate in accordance with Section 10.05(b)) (collectively, “Rights”) pro rata to holders of Common Stock, the Company may, in lieu of making any adjustment pursuant
to this Section 10.05(c), make proper provision so that each Holder of a Security who converts such Security (or any 
  

 -61- 

 portion thereof) on or after the record date for such distribution and prior to the expiration or
redemption of the Rights shall be entitled to receive upon such conversion, in addition to any consideration otherwise payable as herein provided upon such conversion, a number of Rights, per $1,000 principal amount of such Security, to be
determined as follows: (i) if such conversion occurs on or prior to the date for the distribution to the holders of Rights of separate certificates evidencing such Rights (the “Distribution Date”), the same number of Rights to
which a holder of a number of shares of Common Stock equal to the Conversion Rate in effect at the close of business on such record date (or, in the event such distribution is pursuant to a stockholders’ rights plan, equal to the number of Net
Shares that would be issuable in accordance herewith if such Security were surrendered for conversion immediately before the close of business on such record date) would be entitled at the time of such conversion in accordance with the terms and
provisions of and applicable to the Rights; and (ii) if such conversion occurs after the Distribution Date, the same number of Rights to which a holder of a number of shares of Common Stock equal to the Conversion Rate in effect immediately
prior to the Distribution Date (or, in the event such distribution is pursuant to a stockholders’ rights plan, equal to the number of Net Shares that would be issuable in accordance herewith if such Security were surrendered for conversion
immediately before the close of business on the Business Day immediately preceding the Distribution Date) would have been entitled on the Distribution Date in accordance with the terms and provisions of and applicable to the Rights. Any distribution
of rights or warrants pursuant to a stockholders’ rights plan complying with the requirements set forth in the preceding sentence of this paragraph and with Section 10.13 shall not constitute a distribution of rights or warrants
pursuant to this Section 10.05(c). In no event shall the Conversion Rate be decreased pursuant to this Section 10.05(c). 
 (d) In case the Company shall, by dividend or otherwise, at any time make a distribution of cash (excluding any cash that is distributed as part of a distribution requiring a Conversion Rate adjustment pursuant to
Section 10.05(e)) to all or substantially all holders of Common Stock, the Conversion Rate shall be increased by multiplying the Conversion Rate in effect immediately prior to the close of business on the record date for the
determination of holders of Common Stock entitled to such distribution by a fraction (A) whose numerator shall be the current market price per share of Common Stock (as determined pursuant to Section 10.05(g)) on such record date
and (B) whose denominator shall be an amount equal to (I) such current market price per share of Common Stock less (II) the amount of the distribution per share of Common Stock; provided, however, that the Conversion Rate
shall not be adjusted pursuant to this Section 10.05(d) to the extent, and only to the extent, such adjustment would cause the Conversion Price to be less than one cent ($0.01) (which minimum amount shall be subject to appropriate
adjustments, in the good faith determination of the Board of Directors (whose determination shall be described in a Board Resolution), to account for stock splits and combinations, stock dividends, reclassifications and similar events); provided
further that, if the denominator of such fraction shall be equal to or less than zero, the Conversion Rate shall be instead adjusted so that the Conversion 
  

 -62- 

 Price is equal to one cent ($0.01) (as adjusted in accordance with the immediately preceding proviso). An
adjustment to the Conversion Rate pursuant to this Section 10.05(d) shall become effective immediately prior to the opening of business on the day immediately following such record date. In no event shall the Conversion Rate be decreased
pursuant to this Section 10.05(d). 
 (e) In case the Company or any Subsidiary shall distribute cash or other
consideration in respect of a tender offer or exchange offer made by the Company or any Subsidiary for all or any portion of the Common Stock where the sum of the aggregate amount of such cash distributed and the aggregate fair market value (as
determined in good faith by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution), as of the Expiration Date (as defined below), of such other consideration distributed (such sum, the “Aggregate
Amount”) expressed as an amount per share of Common Stock validly tendered or exchanged, and not withdrawn, pursuant to such tender offer or exchange offer as of the Expiration Time (as defined below) (such tendered or exchanged shares of
Common Stock, the “Purchased Shares”) exceeds the current market price per share of Common Stock (as determined pursuant to Section 10.05(g)) on the last date (such last date, the “Expiration Date”) on
which tenders or exchanges could have been made pursuant to such tender offer or exchange offer (as the same may be amended through the Expiration Date), then the Conversion Rate shall be increased by multiplying the Conversion Rate in effect
immediately prior to the close of business on the Expiration Date by a fraction (A) whose numerator is equal to the sum of (I) the Aggregate Amount and (II) the product of (a) the current market price per share of Common Stock (as
determined pursuant to Section 10.05(g)) on the Expiration Date and (b) an amount equal to (i) the number of shares of Common Stock outstanding as of the last time (the “Expiration Time”) at which tenders or
exchanges could have been made pursuant to such tender offer or exchange offer (including all Purchased Shares) less (ii) the Purchased Shares and (B) whose denominator is equal to the product of (I) the number of shares of Common
Stock outstanding as of the Expiration Time (including all Purchased Shares) and (II) the current market price per share of Common Stock on the Expiration Date. 
 An increase, if any, to the Conversion Rate pursuant to this Section 10.05(e) shall become effective immediately prior to the
opening of business on the Business Day following the Expiration Date. In the event that the Company or a Subsidiary is obligated to purchase shares of Common Stock pursuant to any such tender offer or exchange offer, but the Company or such
Subsidiary is permanently prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such tender
offer or exchange offer had not been made. If the application of this Section 10.05(e) to any tender offer or exchange offer would result in a decrease in the Conversion Rate, no adjustment shall be made for such tender offer or exchange
offer under this Section 10.05(e). 
  

 -63- 

 (f) In addition to the foregoing adjustments in subsections (a), (b),
(c), (d) and (e) above, the Company, from time to time and to the extent permitted by law and the continued listing requirements of the New York Stock Exchange, may increase the Conversion Rate by any amount for a
period of at least twenty (20) days or such longer period as may be permitted 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, the Conversion Agent and the Securities Agent and shall mail notice of such increase to each Holder of Securities at such
Holder’s address as the same appears on the registry books of the Registrar, at least fifteen (15) days prior to the date on which such increase commences. 
 (g) For the purpose of any computation under subsections (a), (b), (c) or (d) above of this
Section 10.05, the current market price per share of Common Stock on the date fixed for determination of the stockholders entitled to receive the issuance or distribution requiring such computation (the “Determination
Date”) shall be deemed to be the average of the Closing Sale Prices for the ten (10) consecutive Trading Days ending on, and including, the earlier of the Determination Date and the Ex Date with respect to such issuance or
distribution, and, for the purpose of any computation under Section 10.05(e), the current market price per share of Common Stock on the Expiration Date for the tender offer or exchange offer requiring such computation shall be deemed to
be the average of the Closing Sale Price for the ten (10) consecutive Trading Days immediately preceding the Expiration Date; provided, however, that such current market price per share of Common Stock shall be appropriately
adjusted by the Board of Directors, in its good faith determination (which determination shall be described in a Board Resolution), 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 Ex Date of such event occurs, at any time during the period that begins on, and includes, the first day of such ten (10) consecutive Trading Days and ends on, and
includes, the date when the adjustment to the Conversion Rate on account of the event requiring the computation of such current market price becomes effective. 
 The term “Ex Date,” (i) when used with respect to any issuance or distribution, means the first date on which the
Common Stock trades the regular way on the relevant exchange or in the relevant market from which the Closing Sale Price was obtained without the right to receive such issuance or distribution, (ii) when used with respect to any subdivision or
combination of shares of Common Stock, means the first date on which the Common Stock trades the regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective, and (iii) when used with
respect to any tender offer or exchange offer means the first date on which the Common Stock trades the regular way on such exchange or in such market after the expiration time of such tender offer or exchange offer (as it may be amended or
extended). 
  

 -64- 

 10.06 NO ADJUSTMENT. 
 Notwithstanding anything to the contrary in Section 10.05, no adjustment in the Conversion Rate pursuant to Section 10.05 shall be
required until cumulative adjustments amount to one percent (1%) or more of the Conversion Rate as last adjusted (or, if never adjusted, the initial Conversion Rate); provided, however, that any adjustments to the Conversion Rate which
by reason of this Section 10.06 are not required to be made shall be carried forward and taken into account in any subsequent adjustment to the Conversion Rate; provided further, that if the Company shall mail a notice of
Redemption pursuant to Section 3.04, or if a Fundamental Change or Make-Whole Fundamental Change occurs, or if the Securities shall become convertible pursuant to Section 10.01(A)(iv) or Section 10.01(A)(v), then,
in each case, any adjustments to the Conversion Rate that have been, and at such time remain, deferred pursuant to this Section 10.06 shall be given effect, and such adjustments, if any, shall no longer be carried forward and taken into
account in any subsequent adjustment to the Conversion Rate. All calculations under this Article X shall be made to the nearest cent or to the nearest one-millionth of a share, as the case may be. 
 If any rights, options or warrants issued by the Company and requiring an adjustment to the Conversion Rate in accordance with Section 10.05
are only exercisable upon the occurrence of certain triggering events, then the Conversion Rate will not be adjusted as provided in Section 10.05 until the earliest of such triggering event occurs. Upon the expiration or termination of
any such rights, options or warrants without the exercise of such rights, options or warrants, the Conversion Rate then in effect shall be adjusted immediately to the Conversion Rate which would have been in effect at the time of such expiration or
termination had such rights, options or warrants, to the extent outstanding immediately prior to such expiration or termination, never been issued. 
 If any dividend or distribution is declared and the Conversion Rate is adjusted pursuant to Section 10.05 on account of such dividend or distribution, but such dividend or distribution is thereafter not paid or made, the
Conversion Rate shall again be adjusted to the Conversion Rate which would then be in effect had such dividend or distribution not been declared. 
 No adjustment to the Conversion Rate need be made pursuant to Section 10.05 for a transaction if Holders are to participate in the transaction without conversion on a basis and with notice that the Board of Directors determines
in good faith to be fair and appropriate in light of the basis and notice on which holders of Common Stock participate in the transaction (which determination shall be described in a Board Resolution). 
 Notwithstanding anything herein to the contrary, in no event shall the Conversion Rate be increased pursuant to Section 10.05(b),
Section 10.05(c), Section 10.05(d) or Section 10.05(e) to the extent, but only to the extent, such increase shall cause the Conversion Rate applicable to such Security to exceed 15.4679 shares per $1,000 principal
amount (the “BCF Adjustment Cap”); provided, however, that the BCF Adjustment Cap shall be adjusted in the same manner in which the Conversion Rate is to be adjusted pursuant to this Article X for stock splits
and combinations, stock dividends, reclassifications and similar events.

 10.07 OTHER ADJUSTMENTS. 
 In the event that, as a result of an adjustment made pursuant to Section 10.05 hereof, the Holder of any Security thereafter surrendered for
conversion shall become entitled to receive any shares of Capital Stock other than shares of Common Stock, thereafter the Conversion Rate of such other shares so receivable upon conversion of any Security shall be subject to adjustment from time to
time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to Common Stock contained in this Article X. 
 10.08 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 10.05 hereof, as it determines to be advisable in order that any stock dividend, subdivision of shares,
distribution of rights to purchase stock or securities or distribution of securities convertible into or exchangeable for stock made by the Company or to its stockholders will not be taxable to the recipients thereof or in order to diminish any such
taxation. 
 10.09 NOTICE OF ADJUSTMENT. 
 Whenever the Conversion Rate is adjusted, the Company shall promptly mail to Holders at the addresses appearing on the Registrar’s books a notice of
the adjustment and file with the Trustee, the Conversion Agent and the Securities Agent an Officer’s Certificate briefly stating the facts requiring the adjustment and the manner of computing it. The certificate shall be conclusive evidence of
the correctness of such adjustment. 
 10.10 NOTICE OF CERTAIN TRANSACTIONS.

 In the event that: 
 (1) the Company takes any action, or becomes aware of any event, which would require an adjustment in the Conversion Rate, 
 (2) the Company takes any action that would require a supplemental indenture pursuant to Section 10.11, or 
 (3) there is a dissolution or liquidation of the Company, 
 the Company shall mail to Holders at the addresses appearing on
the Registrar’s books, and the Trustee, the Conversion Agent and the Securities Agent, a written notice stating the proposed record, effective or expiration date, as the case may be, of any transaction referred to in clause (1),
(2) or (3) of this Section 10.10. The Company shall mail such notice at least twenty (20) days before such date; however, failure to mail such notice or any defect therein shall not affect the validity of any
transaction referred to in clause (1), (2) or (3) of this Section 10.10. 
  

 -66- 

 10.11 EFFECT OF RECLASSIFICATIONS, CONSOLIDATIONS,
MERGERS, BINDING SHARE EXCHANGES OR SALES ON CONVERSION PRIVILEGE. 
 Except as provided in Section 10.14(E), if any of the following shall occur, namely: (i) any reclassification or change in the Common
Stock issuable upon conversion of Securities (other than a change only in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination of Common Stock), (ii) any consolidation,
merger or binding share exchange to which the Company is a party other than a merger in which the Company is the continuing Person and which does not result in any reclassification of, or change (other than a change in name, or par value, or from
par value to no par value, or from no par value to par value or as a result of a subdivision or combination) in, the Common Stock or (iii) any sale, transfer, lease, conveyance or other disposition of all or substantially all of the property or
assets of the Company, 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, then the Company or such successor or purchasing
Person, as the case may be, shall execute and deliver to the Trustee and the Securities Agent a supplemental indenture in form reasonably satisfactory to the Trustee and the Securities Agent providing that, at and after the effective time of such
reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition, the Holder of each Security then outstanding shall have the right to convert such Security (if otherwise convertible pursuant
to this Article X) into the kind and amount of cash, securities or other property (collectively, “Reference Property”) receivable upon such reclassification, change, consolidation, merger, binding share exchange, sale,
transfer, lease, conveyance or disposition by a holder of a number of shares of Common Stock equal to a fraction whose denominator is one thousand (1,000) and whose numerator is the product of the principal amount of such Security and the
Conversion Rate in effect immediately prior to such reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition (assuming, if holders of Common Stock shall have the opportunity to elect
the form of consideration to receive pursuant to such reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition, that the Collective Election shall have been made with respect to such
election); provided, however, that at and after the effective time of such reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition, the Principal Return payable
hereunder upon conversion of such Security shall continue to be payable in cash and the Daily Conversion Value and Daily Net Shares shall be calculated based on the fair value of the Reference Property instead of the Closing Sale Price per share of
Common Stock. If holders of Common Stock shall have the opportunity to elect the form of consideration to receive pursuant to such reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or
disposition, then the Company shall make adequate provision to give Holders, treated as a single class, a reasonable opportunity to elect the form of such consideration for purposes of determining the composition of the Reference Property referred
to in the immediately preceding sentence, and once such election is made, such election shall apply to all Holders after the effective time of such reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease,
conveyance or disposition. The supplemental indenture referred to in the first sentence of this paragraph shall provide for adjustments of the Conversion Rate which shall be as nearly equivalent as may be practicable to the adjustments of the
Conversion Rate provided for in this Article X. The foregoing, however, shall not in any way 
  

 -67- 

 affect the right a Holder of a Security may otherwise have, pursuant to Section 10.05(c),
Section 10.05(b) or Section 10.13, to receive rights or warrants upon conversion of a Security. If, in the case of any such consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition, the
stock or other securities and property (including cash) receivable thereupon by a holder of Common Stock includes shares of stock or other securities and property of a Person other than the successor or purchasing Person, as the case may be, in such
consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of
the Holders of the Securities as the Board of Directors in good faith shall reasonably determine necessary by reason of the foregoing (which determination shall be described in a Board Resolution). The provisions of this Section 10.11
shall similarly apply to successive consolidations, mergers, binding share exchanges, sales, transfers, leases, conveyances or dispositions. 
 In the event the Company shall execute a supplemental indenture pursuant to this Section 10.11, the Company shall promptly file with the Trustee, the Conversion Agent and the Securities Agent an Officer’s Certificate
briefly stating the reasons therefor, the kind or amount of shares of stock or securities or property (including cash) receivable by Holders of the Securities upon the conversion of their Securities after any such reclassification, change,
consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition and any adjustment to be made with respect thereto. 
 10.12 DISCLAIMER OF THE TRUSTEE, THE CONVERSION AGENT AND THE SECURITIES
AGENT. 
 None of the Trustee, the Conversion Agent or the Securities Agent shall have any duty to determine when an
adjustment under this Article X should be made, how it should be made or what such adjustment should be, but each may accept as conclusive evidence of the correctness of any such adjustment, and shall be protected in relying upon, the
Officer’s Certificate with respect thereto which the Company is obligated to file with the Trustee, the Conversion Agent and the Securities Agent pursuant to Section 10.09 hereof. None of the Trustee, the Conversion Agent or the
Securities Agent makes any representation as to the validity or value of any securities or assets issued upon conversion of Securities, and none of them shall be responsible for the failure by the Company to comply with any provisions of this
Article X. 
 None of the Trustee, the Conversion Agent or the Securities Agent shall be under any responsibility to determine the
correctness of any provisions contained in any supplemental indenture executed pursuant to Section 10.11, but each of them may accept as conclusive evidence of the correctness thereof, and shall be protected in relying upon, an Opinion
of Counsel and the Officer’s Certificate with respect thereto which the Company is obligated to file with the Trustee and the Securities Agent pursuant to Section 10.11 hereof. 
 10.13 RIGHTS DISTRIBUTIONS PURSUANT TO STOCKHOLDERS’ RIGHTS
PLANS. 
 Upon conversion of any Security or a portion thereof, the Company shall make provision for the Holder thereof to
receive, in addition to, and concurrently with the delivery of, the consideration otherwise payable hereunder upon such conversion, the rights described in the Rights Agreement (whether or not the rights have been separated from the Common Stock
prior 
  

 -68- 

 to the time of conversion), but only to the extent such Holder is to receive shares of Common Stock upon such conversion.
In the event that the Company implements a stockholders’ rights plan after the date hereof or amends, supplements or supercedes the Rights Agreement, the Company shall provide that the Holders will receive, upon conversion of their Securities,
in addition to the consideration otherwise payable hereunder upon such conversion, the rights described therein (whether or not the rights have been separated from the Common Stock prior to the time of conversion), but only to the extent such Holder
will receive shares of Common Stock upon such conversion. 
 10.14 INCREASED CONVERSION RATE
APPLICABLE TO CERTAIN NOTES 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 X, at any time during the period (the “Make-Whole Conversion Period”) that begins on, and includes, the date that is thirty (30) calendar days prior to the date
originally announced by the Company as the anticipated effective date of a Make-Whole Fundamental Change (which anticipated effective date the Company shall disclose, in good faith, in the written notice, public announcement and publication referred
to in Section 10.14(D)) and ends on, and includes, the date that is thirty (30) Business Days after the actual effective date of such Make-Whole Fundamental Change (or, if such Make-Whole Fundamental Change also constitutes a
Fundamental Change, the Fundamental Change Repurchase Date applicable 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 X, plus an amount equal to the Make-Whole Applicable Increase; provided, however, that such increase to the Conversion Rate shall not apply if either: 
 (i) such Make-Whole Fundamental Change constitutes a Public Acquirer Fundamental with respect to which the Company shall have duly made,
and given full effect to, an election, pursuant to and in accordance with Section 10.14(E), to make an Acquirer Stock Conversion Right Adjustment; or 
 (ii) such Make-Whole Fundamental Change is announced by the Company but shall not be consummated. 
 The additional consideration payable hereunder on account of any Make-Whole Conversion Applicable Increase with respect to a Security surrendered for
conversion is herein referred to as the “Make-Whole Consideration.” 
 The Make-Whole Consideration due upon a conversion of
a Security by a Holder shall be paid as soon as practicable after the Conversion Date of such conversion, but in no event later than the later of (1) the date such Holder surrenders such Security for such conversion and (2) the third
(3rd) Business Day after the Effective Date of the applicable Make-Whole Fundamental Change. 
  

 -69- 

 (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 of such Make-Whole Fundamental Change (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) prices listed in the table above under
the column titled “Applicable Price,” or if the actual Effective Date of such Make-Whole Fundamental Change is between two dates listed in the table above in the row immediately below the title “Effective Date,” then the
Applicable Increase for such Make-Whole Fundamental Change shall be determined by linear interpolation between the Applicable Increases set forth for such two prices, or for such two dates based on a three hundred and sixty five (365) day year,
as applicable; 
 (ii) if the actual Applicable Price of such Make-Whole Fundamental Change is greater than $170.00 per share
(subject to adjustment as provided in Section 10.14(B)(iii)), or if the actual Applicable Price of such Make-Whole Fundamental Change is less than $64.65 per share (subject to adjustment as provided in Section 10.14(B)(iii)),
then the Applicable Increase shall be equal to zero (0); 
 (iii) if an event occurs that requires, pursuant to this
Article X (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 price set forth in the table above under the
column titled “Applicable Price” shall be deemed to be adjusted so that such price, at and after such time, shall be equal to the product of (1) such price as in effect immediately before such adjustment to such price and (2) a
fraction whose numerator is the Conversion Rate in effect immediately before such adjustment to the Conversion Rate and whose denominator is the Conversion Rate to be in effect, in accordance with this Article X, immediately after such
adjustment to the Conversion Rate; 
  

 -70- 

 (iv) each Applicable Increase amount set forth in the table above shall be adjusted in
the same manner in which, and for the same events for which, the Conversion Rate is to be adjusted pursuant to Section 10.01 through Section 10.13; and 
 (v) in no event shall the Conversion Rate applicable to any Security be increased pursuant to this Section 10.14 to the
extent, but only to the extent, such increase shall cause the Conversion Rate applicable to such Security to exceed 15.4679 shares per $1,000 principal amount (the “BCF Make-Whole Cap”); provided, however, that the BCF
Make-Whole Cap shall be adjusted in the same manner in which, and for the same events for which, the Conversion Rate is to be adjusted pursuant to this Article X. 
 (C) As used herein, “Applicable Price” shall have the following meaning with respect to a Make-Whole Fundamental Change: (a) if such Make-Whole Fundamental Change constitutes a Common Stock
Change Make-Whole Fundamental Change and the consideration (excluding cash payments for fractional shares or pursuant to statutory appraisal rights) for the 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; (b) if such Make-Whole Fundamental Change constitutes an
Asset Sale Make-Whole Fundamental Change and the consideration paid for the property and assets of the Company consists solely of cash, then the “Applicable Price” with respect to such Make-Whole Fundamental Change shall be equal to the
cash amount paid for the property and assets of the Company, expressed as an amount per share of Common Stock outstanding on the Effective Date of such Make-Whole Fundamental Change; and (c) 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 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 (which determination shall be described in a Board Resolution), 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 Ex Date of such event occurs, at any time during such five (5) consecutive Trading Days. 
 (D) At least thirty (30) calendar days before the first anticipated effective date of each proposed Make-Whole Fundamental Change, the Company shall
mail to each Holder, in accordance with Section 12.02, written notice of, and shall publicly announce, through a reputable national newswire service, and publish on the Company’s website, the anticipated effective date of such
proposed Make-Whole Fundamental Change. Each such notice, announcement and publication shall also state (i) that the Company either (a) has elected, in accordance with Section 10.14(E), to make an Acquirer Stock Conversion
Right Adjustment with respect to such Make-Whole Fundamental Change in lieu of increasing the Conversion Rate pursuant to Section 10.14(A) or (b) has elected not to make an Acquirer Stock Conversion Right 
  

 -71- 

 Adjustment with respect to such Make-Whole Fundamental Change; and (ii) if the Company has elected not to make such
Acquirer Stock Conversion Right Adjustment with respect to such Make-Whole Fundamental Change, 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). No later than the
third Business Day after the Effective Date of each Make-Whole Fundamental Change, the Company shall mail, in accordance with Section 12.02, written notice of, and shall publicly announce, through a reputable national newswire service,
and publish on the Company’s website, such Effective Date and the Applicable Increase applicable to such Make-Whole Fundamental Change. 
 (E) Notwithstanding anything to the contrary in this Section 10.14, if the Company shall make any mailing, announcement or publication referred to in Section 10.14(D) in respect of a Make-Whole Fundamental Change
that shall also constitute a Public Acquirer Fundamental Change, then the Company shall have the right to, in lieu of increasing the Conversion Rate pursuant to Section 10.14(A) in connection with such Make-Whole Fundamental Change,
cause the right to convert the Securities in accordance with this Article X to change such that, from and after the effective time of such Public Acquirer Fundamental Change, the Holder of each Security then outstanding shall have the right
to convert such Security (if otherwise convertible pursuant to this Article X) solely into shares of the Public Acquirer Common Stock applicable to such Public Acquirer Fundamental Change (except that, at and after such effective time, the
Principal Return payable hereunder upon conversion of such Security shall continue to be payable in cash and the Daily Conversion Value and Daily Net Shares shall be calculated by reference to the Closing Sale Price per share of such Public Acquirer
Common Stock as opposed to the Closing Sale Price per share of the Common Stock), at an initial Conversion Rate (which shall take effect at such effective time, but which shall thereafter be subject to adjustment in the same manner in which, and for
the same events for which, the Conversion Rate is to be adjusted pursuant to this Article X) equal to the Conversion Rate in effect immediately before such effective time multiplied by a fraction whose numerator is the fair market value (as
determined in good faith by the Board of Directors, which determination shall be described in a Board Resolution), as of such effective time, of the cash, securities and other property paid or payable pursuant to such Public Acquirer Fundamental
Change per share of Common Stock and whose denominator is the average of the last reported sale prices per share of such Public Acquirer Common Stock for the five (5) consecutive trading days commencing on, and including, the trading day
immediately after the effective date of such Public Acquirer Fundamental Change, which average shall be appropriately adjusted by the Board of Directors, in its good faith determination (which determination shall be described in a Board Resolution),
to account for any event that, assuming such Public Acquirer Common Stock were Common Stock, would require, pursuant hereto, an adjustment to the Conversion Rate to become effective, or any such event whose Ex Date occurs, at any time during such
five (5) consecutive trading days. Any such change in the right to convert the Securities in accordance with this Section 10.14(E) is herein referred to as an “Acquirer Stock Conversion Right Adjustment.”

  

 -72- 

 If the Company shall have elected, in accordance with this Section 10.14(E), to make an
Acquirer Stock Conversion Right Adjustment with respect to a Public Acquirer Fundamental Change, then: 
 (i) the Company
shall cause there to be executed and delivered to the Trustee and the Securities Agent a supplemental indenture in form reasonably satisfactory to the Trustee and the Securities Agent, which supplemental indenture shall (a) give due effect to
such election in accordance with this Section 10.14(E), including, without limitation, evidencing a binding and enforceable obligation of the issuer of the applicable Public Acquirer Common Stock to satisfy the right of Holders to
convert Securities in accordance with this Article X and this Section 10.14(E); (b) be executed by, without limitation, such issuer; (c) contain such additional provisions to protect the interests of the Holders of the
Securities as the Board of Directors in good faith shall reasonably determine (which determination shall be described in a Board Resolution); and (d) be in full force and effect no later than the effective time of such Public Acquirer
Fundamental Change; 
 (ii) the Company shall promptly file with the Trustee and the Securities Agent an Officer’s
Certificate briefly stating the reasons for such supplemental indenture, the nature of the change in the conversion right pursuant to such Acquirer Stock Conversion Right Adjustment and the Conversion Rate as adjusted therefor; 
 (iii) the provisions of Section 10.11 shall not apply to such Public Acquirer Fundamental Change, provided such Public
Acquirer Fundamental Change shall have been duly given effect in accordance with this Section 10.14(E); and 
 (iv) such election shall be irrevocable with respect to such Public Acquirer Fundamental Change and shall be deemed to have been made at the time the Company shall, with respect to such Public Acquirer Fundamental Change, mail the first
notice, or make the first public announcement or publication, whichever shall occur earlier, referred to in Section 10.14(D) (it being understood that the Company shall discharge its obligations hereunder in good faith in determining
whether an announced transaction and a completed transaction are deemed, for purposes of this clause (iv), to be the same Public Acquirer Fundamental Change despite differences in the announced terms and the terms as such transaction was
consummated); provided, however, that the Company shall not be obligated to give effect to such an election with respect to a Public Acquirer Fundamental Change that has been announced by the Company but that shall not be consummated.

 For avoidance of doubt, any change, pursuant to this Section 10.14(E), in the right of Holders to convert Securities shall
apply to all Holders. 
 (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 IV with respect to a Public Acquirer Fundamental Change or Make-Whole Fundamental Change. 
 (G) Nothing in this Section 10.14 shall prevent an adjustment to the Conversion Rate pursuant to Section 10.05 in respect of a Make-Whole Fundamental Change or a Public Acquirer Fundamental
Change. 
  

 -73- 

 XI. TAX TREATMENT 
 11.01 TAX TREATMENT. 
 The Company hereby agrees and by purchasing an interest in
a Security, each Holder and each Person (including an entity) that acquires a direct or indirect beneficial interest in the Security hereby agrees that such Person shall (except to the extent otherwise required by final administrative or judicial
determinations to the contrary): 
 (A) treat the Securities as indebtedness of the Company for all U.S. federal income tax purposes;

 (B) treat the Securities as debt instruments that are subject to Treasury Regulation section 1.1275-4 (the “CPDI
Regulations”); 
 (C) treat the delivery of Common Stock or cash (including cash delivered in lieu of a fractional share) to a
Holder of a Security upon conversion of such Security, as a contingent payment (in an amount equal to the sum of the fair market value of such Common Stock and any cash received) under the CPDI Regulations; and 
 (D) treat accrued interest with respect of the Securities (irrespective of whether or not actually paid) as ordinary income for U.S. federal income tax
purposes to the extent required by the CPDI Regulations, and treat any gains realized on sale, exchange, redemption or conversion of the Securities as ordinary income for U.S. federal income tax purposes to the extent required by the CPDI
Regulations. 
 11.02 COMPARABLE YIELD AND PROJECTED PAYMENT
SCHEDULE. 
 Solely for purposes of applying Treasury Regulation section 1.1275-4 to the Securities:

 (A) for U.S. federal income tax purposes, the Company shall accrue interest with respect to outstanding Securities as original issue

Exhibit E hereto; and 
 (B) the Company acknowledges and agrees, and each Holder and any beneficial holder of a Security by its
purchase of a Security shall be deemed to acknowledge and agree (A) to the Company’s determination of the comparable yield and the projected payment schedule, attached as Exhibit E hereto, (B) that the comparable yield and the
projected payment schedule are not determined for any purpose other than for the purpose of applying the CPDI Regulations to the Security, (C) that the comparable yield and the projected payment schedule do not constitute a projection or
representation regarding the future stock price or the actual amounts payable on the Securities, and (D) that the Company’s application of the CPDI Regulations, including the Company’s determination of the comparable yield and the
projected payment schedule, as attached as Exhibit E hereto, shall be binding on each Holder and any beneficial holder of a Security (except to the extent otherwise required by final administrative or judicial determinations to the contrary).

Security hereby agrees: 
 (A) that the Company may withhold any tax, to the extent it is required to do so under any law or regulation
(whether based on accrued, constructive or cash income), from any payments of cash or shares of Common Stock (including Common Stock to be paid upon conversion) to be made to a Holder or Person holding a direct or indirect beneficial interest in a
Security or in shares of Common Stock received upon conversion of a Security; and 
 (B) that if the Company pays any withholding taxes on
behalf of a Holder or Person holding a direct or indirect beneficial interest in a Security, as a result of an adjustment to the Conversion Rate or a failure to make an adjustment to the Conversion Rate, the Company may, in its discretion, reduce
any payments to such Holder or Person of cash or shares of Common Stock (including any Common Stock to be paid upon conversion) on the Security by the amounts of any such withholding taxes paid.

 [REVERSE OF SECURITY] 
 MILLIPORE CORPORATION 
 3.75% Convertible Senior Note due 2026 
 1. Interest. Millipore Corporation, a Massachusetts corporation (the “Company”), promises to pay interest on the principal amount
of this Security at the rate per annum shown above. The Company will pay interest, payable semi-annually in arrears, on June 1 and December 1 of each year, with the first payment to be made on December 1, 2006. Interest on the
Securities will accrue on the principal amount from, and including, the most recent date to which interest has been paid or provided for or, if no interest has been paid, from, and including, June 13, 2006, in each case to, but excluding, the
next interest payment date or Maturity Date, as the case may be. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 
 In addition, if the average Contingent Interest Trading Price of a Security for the five (5) consecutive trading day period (the “Contingent Interest Measurement Period”) preceding the first day of any six
(6) month period (each a “Contingent Interest Period”) from and including an interest payment date to but excluding the next interest payment date, commencing with the six (6) month period beginning December 1, 2011,
is equal to or greater than one hundred and twenty percent (120%) of the principal amount of such Security, then the Company shall pay contingent interest (“Contingent Interest”) to the Holders. 
 The amount of Contingent Interest payable per $1,000 principal amount of Securities in respect of any Contingent Interest Period, if applicable, shall be
equal to 0.175% of the average Contingent Interest Trading Price per $1,000 principal amount of the Securities during the five (5) consecutive trading day period preceding the first day of such Contingent Interest Period. Contingent Interest
shall accrue from the first day of the applicable Contingent Interest Period through, but excluding, the interest payment date at the end of such Contingent Interest Period, and Contingent Interest shall be payable to Holders in the same manner as
regular cash interest. Regular cash interest shall continue to accrue at the per annum rate of 3.75% on the principal amount of the Securities whether or not Contingent Interest is paid. 
 The Company shall instruct the Bid Solicitation Agent to determine the daily Contingent Interest Trading Prices of the Securities during each Contingent
Interest Measurement Period during which any Securities are outstanding. Upon determining that the Securities shall begin to accrue Contingent Interest during a Contingent Interest Period, the Company shall, on or before the start of such Contingent
Interest Period, publicly announce, through a reputable national newswire service, and publish on the Company’s website, the fact that Contingent Interest has become payable and the amount of such Contingent Interest payable per $1,000
principal amount of Securities. 
 The “Contingent Interest Trading Price” of a Security on any trading day means the
average secondary market bid quotations obtained by the Bid Solicitation Agent for five million dollars ($5,000,000) principal amount of Securities at approximately 4:00 p.m., New York City time, on such trading day from three (3) independent
nationally recognized securities dealers 
  

 E-4 

 selected by the Company; provided, however, that if the Bid Solicitation Agent can reasonably obtain only
two (2) such bids, then the average of such two (2) bids shall instead be used, and if the Bid Solicitation Agent can reasonably obtain only one (1) such bid, then such one (1) bid shall be used; provided further, that if
the Bid Solicitation Agent cannot reasonably obtain at least one (1) such bid, then the Contingent Interest Trading Price per $1,000 principal amount of the notes shall be determined by a nationally recognized securities dealer retained by the
Company for such purpose. 
 2. Maturity. The Securities will mature on June 1, 2026. 
 3. Method of Payment. Except as provided in the Indenture (as defined below), the Company will pay interest on the Securities to the persons who
are Holders of record of Securities at the close of business on the record date set forth on the face of this Security next preceding the applicable interest payment date. Holders must surrender Securities to a Paying Agent to collect the principal
amount, Redemption Price, Option Purchase Price or Fundamental Change Repurchase Price of the Securities, plus, if applicable, accrued and unpaid interest, if any, payable as herein provided upon Redemption, Purchase at Holder’s Option or
Repurchase Upon Fundamental Change, as the case may be. 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 this Security is in global form, by wire transfer of immediately available funds to the account designated by the Depositary or its nominee; (B) in the case this Security is held, other than
global form, by a Holder of more than five million dollars ($5,000,000) in aggregate principal amount of Securities, by wire transfer of immediately available funds to the account specified 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; and (C) in the case this Security is held, other than global form, by a Holder of five million dollars ($5,000,000) or less in aggregate
principal amount of Securities, by mailing a check to the address of such Holder set forth in the register of the Registrar. 
 4. Paying
Agent, Registrar, Conversion Agent. Initially, Citibank, N.A., (the “Securities Agent”) will act as Paying Agent, Registrar, Bid Solicitation Agent and Conversion Agent. The Company may change any Paying Agent, Registrar, Bid
Solicitation Agent or Conversion Agent without notice. 
 5. Indenture. The Company issued the Securities under an Indenture dated as
of June 13, 2006 (the “Indenture”) among the Company, Wilmington Trust Company, as trustee (the “Trustee”), and the Securities Agent. The terms of the Securities include those stated in the Indenture and those
made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb) (the “TIA”) as amended and in effect from time to time. The Securities are subject to all such terms, and Holders
are referred to the Indenture and the TIA for a statement of such terms. The Securities are general unsecured senior obligations of the Company limited to $550,000,000 aggregate principal amount ($632,500,000 if the Initial Purchasers have elected
to exercise in full the Option to purchase up to an additional $82,500,000 aggregate principal amount of the Securities), except as otherwise provided in the Indenture (except for Securities issued in substitution for destroyed, mutilated, lost or
stolen Securities). Terms used herein without definition and which are defined in the Indenture have the meanings assigned to them in the Indenture. 
  

 E-5 

 6. Optional Redemption. 
 The Company shall have the right, at the Company’s option, at any time, and from time to time, on a Redemption Date on or after December 1,
2011, to redeem all or any part of the Securities at a price payable in cash equal to one hundred percent (100%) of the principal amount of the Securities to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the
Redemption Date. The Company will make at least eleven (11) semi-annual interest payments with respect to the Securities prior to redeeming any Securities pursuant to this paragraph. 
 In addition, if the Serologicals Merger is not consummated, then the Company shall have the right, at the Company’s option, at any time, and from
time to time, on a Redemption Date on or before October 10, 2006, to redeem all or any part of the Securities at a price payable in cash equal to one hundred and one percent (101%) of the principal amount of the Securities to be so
redeemed, plus the Conversion Premium, if any, plus any accrued and unpaid interest to, but excluding, such Redemption Date. 
 7. Notice
of Redemption. Notice of Redemption will be mailed at least thirty (30) days but not more than sixty (60) days before the Redemption Date (or, with respect to a Serologicals Redemption, not less than seven (7) nor more than thirty
(30) days before the Redemption Date) to each Holder of Securities to be redeemed at its address appearing in the security register. Securities in denominations larger than $1,000 principal amount may be redeemed in part but only in integral
multiples of $1,000 principal amount. 
 8. Purchase by the Company at the Option of the Holder. Subject to the terms and conditions
of the Indenture, the Company shall become obligated to purchase, at the option of each Holder, the Securities held by such Holder on December 1, 2011, June 1, 2016 and June 1, 2021 (each, an “Option Purchase
Date”) at an Option Purchase Price, payable in cash, equal to one hundred percent (100%) of the principal amount of the Securities to be purchased, plus accrued and unpaid interest, if any, to, but excluding, the applicable Option
Purchase Date, upon delivery of a Purchase Notice containing the information set forth in the Indenture, at any time from the opening of business on the date that is twenty (20) Business Days prior to the applicable Option Purchase Date until
the close of business on the third (3rd) Business Day immediately preceding the applicable Option Purchase Date and upon delivery of the Securities to the Paying Agent by the Holder as set forth in the Indenture; provided,
however, that that such accrued and unpaid interest shall be paid to the Holder of record of such Securities at the close of business on the record date immediately preceding such Option Purchase Date 
 9. Repurchase at Option of Holder Upon a Fundamental Change. Subject to the terms and conditions of the Indenture, in the event of a Fundamental
Change, each Holder of the Securities shall have the right, at the Holder’s option, to require the Company to repurchase such Holder’s Securities including any portion thereof which is $1,000 in principal amount or any integral multiple
thereof on a date selected by the Company (the “Fundamental Change Repurchase Date”), which date is no later than thirty five (35) days, nor earlier than twenty (20)
  

 E-6 

 days, after the date on which notice of such Fundamental Change is mailed in accordance with the Indenture, at a price
payable in cash equal to one hundred percent (100%) of the principal amount of such Security, plus accrued and unpaid interest to, but excluding, the Fundamental Change Repurchase Date; 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 accrued and unpaid interest, if any, to, but excluding, such interest payment date will be paid
on such interest payment date to the Holder of record of such Securities at the close of business on such record date, and the Holder surrendering such Securities for repurchase will not be entitled to any such accrued and unpaid interest unless
such Holder was also the Holder of record of such Securities at the close of business on such record date. 
 10. Conversion.

 Conversion Based on Closing Sale Price of Common Stock. Subject to earlier Redemption, Purchase at Holder’s Option or
Repurchase Upon Fundamental Change, Holders may surrender Securities in integral multiples of $1,000 principal amount for conversion into cash and, if applicable, shares of Common Stock on any Business Day of a calendar quarter after the calendar
quarter ending September 30, 2006, if the Closing Sale Price for each of twenty (20) or more Trading Days in a period of thirty (30) consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar quarter
exceeds one hundred and twenty percent (120%) of the Conversion Price in effect on the last Trading Day of the immediately preceding calendar quarter. Solely for purposes of determining whether the Securities shall have become convertible
pursuant to this paragraph, the Board of Directors shall, in its good faith determination, which shall be described in a Board Resolution, make appropriate adjustments to the Closing Sale Prices and/or such Conversion Price used to determine whether
the Securities shall have become convertible pursuant to this paragraph to account for any adjustments to the Conversion Rate which shall have become effective, or any event requiring an adjustment to the Conversion Rate where the Ex Date of such
event occurs, during the period of thirty (30) consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar quarter. 
 Conversion Upon Satisfaction of Trading Price Condition. Subject to earlier Redemption, Purchase at Holder’s Option or Repurchase Upon Fundamental Change, Holders may surrender Securities in integral
multiples of $1,000 principal amount for conversion into cash and, if applicable, shares of Common Stock during the five (5) consecutive Business Days immediately after any five (5) consecutive Trading Day period (such five
(5) consecutive Trading Day period, the “Note Measurement Period”) in which the average Trading Price per $1,000 principal amount of the Securities was equal to or less than ninety seven percent (97%) of the average
Conversion Value (as defined below) during the Note Measurement Period (such condition, the “Trading Price Condition”). The Bid Solicitation Agent shall not have any obligation to determine the Trading Price unless the Company has
requested such determination in writing, and the Company shall have no obligation to make such request unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of the Securities would be equal
to or less than ninety seven percent (97%) of the product of the Closing Sale Price and the Conversion Rate. Upon receipt of such evidence, the Company shall instruct the Bid Solicitation Agent in writing to determine the Trading Price per

  

 E-7 

 $1,000 principal amount of the Securities for each of the five (5) successive Trading Days immediately after the
Company receives such evidence and on each Trading Day thereafter until the first Trading Day on which the Trading Price Condition is no longer satisfied. For purposes of this paragraph, the “Conversion Value” per $1,000 principal
amount of Securities, on a given Trading Day, means the product of the Closing Sale Price on such Trading Day and the Conversion Rate in effect on such Trading Day. 
 Conversion Based on Redemption. A Security, or portion of a Security, which has been called for Redemption pursuant to paragraph 6 may be surrendered in integral multiples of $1,000 principal amount for
conversion into cash and, if applicable, shares of Common Stock; provided, however, that such Security or portion thereof may be surrendered for conversion pursuant to this paragraph only until the close of business on the third
(3rd) Business Day immediately preceding the Redemption Date. 
 Conversion Upon Certain Distributions. Subject to
earlier Redemption, Purchase at Holder’s Option or Repurchase Upon Fundamental Change, if the Company takes any action, or becomes aware of any event, that would require an adjustment to the Conversion Rate pursuant to Sections 10.05(b),
10.05(c), 10.05(d) or 10.05(e) of the Indenture, the Securities may be surrendered for conversion in integral multiples of $1,000 principal amount into cash and, if applicable, shares of Common Stock beginning on the date the
Company mails the notice to the Holders as provided in Section 10.10 of the Indenture (or, if earlier, the date the Company is required to mail such notice) and at any time thereafter until the close of business on the Business Day
immediately preceding the Ex Date (as defined in Section 10.05(g) of the Indenture) of the applicable transaction or until the Company announces that such transaction will not take place. 
 Conversion Upon Occurrence of Certain Corporate Transactions. Subject to earlier Redemption, Purchase at Holder’s Option or Repurchase Upon
Fundamental Change, if either: 
 (i) a Fundamental Change occurs; or 
 (ii) the Company is a party to a consolidation, merger or binding share exchange 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, 
 then, in each case, the Securities may be surrendered for
conversion into cash and, if applicable, shares of Common Stock at any time during the period that begins on, and includes, the date that is thirty (30) calendar days prior to the date originally announced by the Company as the anticipated
effective date of such Fundamental Change, consolidation, merger or binding share exchange (which anticipated effective date the Company shall disclose, in good faith, in the written notice, public announcement and publication referred to in
Section 10.01(C) of the Indenture) and ends on, and includes, the date that is thirty (30) calendar days after the actual effective date of such Fundamental Change, consolidation, merger or binding share exchange; provided,
however, that if such Fundamental Change, consolidation, merger or binding share exchange shall also constitute a Make-Whole Fundamental Change, then the Securities may also be surrendered for conversion into cash and, if applicable, shares
of Common Stock at any time during the Make-Whole Conversion Period applicable to such Make-Whole Fundamental Change. 
  

 E-8 

 Conversion on or after June 1, 2024 and at any time from November 1, 2011 to
December 1, 2011. Subject to earlier Redemption, Purchase at Holder’s Option or Repurchase Upon Fundamental Change, the Securities may be surrendered for conversion into cash and, if applicable, shares of Common Stock at any time on or
after June 1, 2024 and at any time from, and including, November 1, 2011 to, and including, December 1, 2011. 
 To convert a
Security, a Holder must (1) complete and sign the Conversion Notice, with appropriate signature guarantee, on the back of the Security, (2) surrender the Security to a Conversion Agent, (3) furnish appropriate endorsements and
transfer documents if required by the Registrar or Conversion Agent, (4) pay the amount of interest, if any, the Holder must pay in accordance with the Indenture and (5) pay any tax or duty if required pursuant to the Indenture. A Holder
may convert a portion of a Security if the portion is $1,000 principal amount or an integral multiple of $1,000 principal amount. 
 Upon
conversion of a Security, the Holder thereof shall be entitled to receive the cash and, if applicable, shares of Common Stock payable upon conversion in accordance with Article X of the Indenture. 
 The initial Conversion Rate is 11.0485 shares of Common Stock per $1,000 principal amount of Securities (which results in an effective initial Conversion
Price of approximately $90.51 per share) subject to adjustment in the event of certain circumstances as specified in the Indenture. The Company will deliver cash in lieu of any fractional share. On conversion, no payment or adjustment for any unpaid
and accrued interest, Contingent Interest or additional interest on the Securities will be made. If a Holder surrenders a Security for conversion after the close of business on the record date for the payment of an installment of interest and prior
to the related interest payment date, such Security, when surrendered for conversion, must be accompanied by payment of an amount equal to the interest thereon which the registered Holder at the close of business on such record date is to receive
(other than overdue interest, if any, that has accrued on such Security), unless such Security has been called for Redemption as described in the Indenture. 
 The Conversion Rate applicable to each Security that is surrendered for conversion, in accordance with the Securities and Article X of the Indenture, at any time during the Make-Whole Conversion Period with

any tax or similar governmental charge that may be imposed in connection with certain transfers or exchanges. The Company or the Securities Agent, as the case may be, shall not be required to register the transfer of or exchange any Security
(i) during a period beginning at the opening of business twenty (20) days before the mailing of a notice of redemption of the Securities selected for Redemption under Section 3.04 of the Indenture and ending at the close of

corporation organized and existing under the laws of the United States, any State thereof or the District of Columbia; (ii) such person assumes by supplemental indenture all the obligations of the Company under the Securities and the Indenture;
and (iii) immediately after giving effect to the transaction, no Default or Event of Default shall exist. 
 14. Amendments,
Supplements and Waivers. Subject to certain exceptions, the Indenture or the Securities may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the outstanding Securities, and
certain existing Defaults or Events of Default may be waived with the consent of the Holders of a majority in aggregate principal amount of the Securities then outstanding. In accordance with the terms of the Indenture, the Company, with the consent
of the Trustee and the Securities Agent, may amend or supplement this Indenture or the Securities without notice to or the consent of any Securityholder: (i) to comply with Sections 5.01 and 10.11 of the Indenture and, in
accordance with Section 10.14(E) of the Indenture, to give effect to an election, pursuant to such Section 10.14(E), by the Company to make an Acquirer Stock Conversion Right Adjustment with respect to a Public Acquirer
Fundamental Change; (ii) to make any changes or modifications to the Indenture necessary in connection with the registration of the Securities under the Securities Act pursuant to the Registration Rights Agreement or the qualification of the

power conferred upon the Company; and (v) to make provisions with respect to adjustments to the Conversion Rate as required by the Indenture or to increase the Conversion Rate in accordance with the Indenture. In addition, the Company,

  

 E-10 

 the Trustee and the Securities Agent may enter into a supplemental indenture without the consent of Holders of the
Securities to cure any ambiguity, defect, omission or inconsistency in the Indenture in a manner that does not, individually or in the aggregate with all other modifications made or to be made to the Indenture, adversely affect the rights of any
Holder in any material respect. 
 15. Defaults and Remedies. 
 If an Event of Default (excluding an Event of Default specified in Section 6.01(viii) or (ix) of the Indenture with respect to the
Company (but including an Event of Default specified in Section 6.01(viii) or (ix) of the Indenture solely with respect to a Significant Subsidiary of the Company or any group of Subsidiaries that in the aggregate would
constitute a Significant Subsidiary of the Company)) occurs and is continuing, the Trustee by notice to the Company or the Holders of at least twenty five percent (25%) in principal amount of the Securities then outstanding by notice to the
Company and the Trustee may declare the Securities to be due and payable. Upon such declaration, the principal of, and any premium and accrued and unpaid interest (including any Contingent Interest and additional interest) on, all Securities shall
be due and payable immediately. If an Event of Default specified in Section 6.01(viii) or (ix) of the Indenture with respect to the Company (excluding, for purposes of this sentence, an Event of Default specified in
Section 6.01(viii) or (ix) of the Indenture solely with respect to a Significant Subsidiary of the Company or any group of Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company) occurs,
the principal of, and premium and accrued and unpaid interest (including any Contingent Interest and additional interest) on, all the Securities shall ipso facto become and be immediately due and payable without any declaration or other act
on the part of the Trustee or any Holder. 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 (A) the
rescission would not conflict with any order or decree, (B) all existing Events of Default, except the nonpayment of principal, premium or interest (including Contingent Interest and additional interest) that has become due solely because of
the acceleration, have been cured or waived and (C) all amounts due to the Trustee and the Securities Agent under Section 7.07 of the Indenture have been paid. 
 Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Holders of a majority in aggregate principal amount of
the Securities then outstanding may 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. However, the Trustee may refuse to follow any direction that
conflicts with law or the Indenture, is unduly prejudicial to the rights of other Holders or would involve the Trustee in personal liability unless the Trustee is offered indemnity reasonably satisfactory to it; provided, that the Trustee may
take any other action deemed proper by the Trustee which is not inconsistent with such direction. 
 If a Default or Event of Default occurs
and is continuing as to which the Trustee has received written notice pursuant to the provisions of the Indenture, or as to which a Responsible Officer of the Trustee shall have actual knowledge, the Trustee shall mail to each Holder a notice of the
Default or Event of Default within thirty (30) days after it occurs unless such Default or Event of Default has been cured or waived. Except in the case of a Default or Event of Default in payment of any amounts due with respect to any
Security, the Trustee may 
  

 E-11 

 withhold the notice if, and so long as it in good faith determines that, withholding the notice is in the best interests
of Holders. The Company must deliver to the Trustee and the Securities Agent an annual compliance certificate. 
 16. Registration
Rights. The Holders are entitled to registration rights as set forth in the Registration Rights Agreement. The Holders shall be entitled to receive additional interest in certain circumstances, all as set forth in the Registration Rights
Agreement. 
 17. Trustee’s and Securities Agent’s Dealings with the Company. Each of the Trustee and the Securities Agent,
and each banking institution, if any, serving as successor Trustee or Securities Agent thereunder, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for, the Company or its Affiliates, and may
otherwise deal with the Company or its Affiliates, as if it were not Trustee or Securities Agent, as applicable. 
 18. No Recourse
Against Others. No past, present or future director, officer, employee or stockholder, as such, of the Company shall have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in
respect of, or by reason of, such obligations or their creation. Each Holder, by accepting a Security, waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities. 
 19. Authentication. This Security shall not be valid until authenticated by the manual signature of the Securities Agent or an authenticating
agent in accordance with the Indenture. 
 20. Abbreviations. Customary abbreviations may be used in the name of a Holder or an
assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entirety), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (Uniform Gifts to Minors Act).

Statement to become effective under the Securities Act (including obtaining the prompt withdrawal of any order suspending the effectiveness of such Shelf Registration Statement) or promptly cause such Shelf Registration Statement to be useable for
purposes contemplated hereunder, and in any event shall, within thirty (30) days, (i) amend such Shelf Registration Statement in a

 manner reasonably expected to cause the same to become usable for the purposes contemplated hereunder or
obtain the withdrawal of any order suspending the effectiveness of such Shelf Registration Statement, as applicable, or (ii) file an additional Registration Statement (a “Subsequent Shelf Registration Statement”) for an
offering to be made on a delayed or continuous basis pursuant to Rule 415 registering the resale from time to time by Holders thereof of all securities that are Registrable Securities as of the time of such filing (or, if registration of Registrable
Securities not held by Notice Holders is not permitted by the rules and regulations of the SEC, then registering the resale from time to time by Notice Holders of their securities that are Registrable Securities as of the time of such filing). If a
Subsequent Shelf Registration Statement is filed, the Company shall use its reasonable best efforts to (A) cause such Subsequent Shelf Registration Statement to become effective under the Securities Act as promptly as practicable after such
filing, but in no event later than the Subsequent Shelf Registration Statement Effectiveness Deadline Date and (B) keep such Subsequent Shelf Registration Statement (or another Subsequent Shelf Registration Statement) continuously effective
until the end of the Effectiveness Period (except to the extent permitted under Section 3(j)). Each such Subsequent Shelf Registration Statement, if any, shall provide for the registration of such Registrable Securities for resale by such
Holders in accordance with the reasonable methods of distribution indicated in their Notice and Questionnaires (provided, however, that in no event will such methods of distribution take the form of an underwritten offering of
Registrable Securities without the Company’s prior written consent, which the Company may withhold in its sole discretion). 
 (c) Subject to Section 2(d)(i)(A), the Company shall supplement and amend any Shelf Registration Statement if required by the rules, regulations or instructions applicable to the registration form used by the Company for such Shelf
Registration Statement, if required by the Securities Act or as reasonably requested by the Initial Purchasers or by the Trustee on behalf of the Holders of the Registrable Securities covered by such Shelf Registration Statement. 
 (d) 
 (i) Each
Holder of Registrable Securities agrees that, if such Holder wishes to sell Registrable Securities pursuant to a Shelf Registration Statement and related Prospectus, it will do so only in accordance with this Section 2(d) and Section 3(j).
Each Holder of Registrable Securities wishing to sell Registrable Securities pursuant to a Shelf Registration Statement and related Prospectus agrees to deliver a completed and executed Notice and Questionnaire to the Company prior to any attempted
or actual distribution of Registrable Securities under a Shelf Registration Statement. If a Holder becomes a Notice Holder after the fifth (5th) Business Day before the date the Initial Shelf Registration Statement becomes effective under the
Securities Act, the Company shall, within thirty (30) days after the date such Holder became a Notice Holder (or, if a Suspension Period either is in effect when such Holder became a Notice Holder or is put into effect within five
(5) Business Days after the date such Holder became a Notice Holder, then within thirty (30) days after the expiration of such Suspension Period), 
  

 - 7 - 

 (A) file with the SEC a supplement to the related Prospectus (or, if required by
applicable law, a post-effective amendment to the Shelf Registration Statement or a Subsequent Shelf Registration Statement), and all other document(s), in each case as is required so that such Notice Holder is named as a selling securityholder in a
Shelf Registration Statement and the related Prospectus in such a manner as to permit such Notice Holder to deliver a Prospectus to purchasers of the Registrable Securities in accordance with the Securities Act; provided, however,
that, if a post-effective amendment or a Subsequent Shelf Registration Statement is required by the rules and regulations of the SEC in order to permit resales by such Notice Holder, the Company shall not be required to file more than one
(1) post-effective amendment or Subsequent Shelf Registration Statement for such purpose in any ninety (90) day period; provided further, that in no event shall the Company be obligated to file more than one (1) such
supplement in any thirty (30) day period; 
 (B) if, pursuant to Section 2(d)(i)(A), the Company shall have filed a
post-effective amendment to the Shelf Registration Statement or filed a Subsequent Shelf Registration Statement, the Company shall use its reasonable best efforts to cause such post-effective amendment or Subsequent Shelf Registration Statement, as
the case may be, to become effective under the Securities Act as promptly as practicable, but in any event by the date (the “Amendment Effectiveness Deadline Date,” in the case of a post-effective amendment, and the
“Subsequent Shelf Registration Statement Effectiveness Deadline Date,” in the case of a Subsequent Shelf Registration Statement) that is forty five (45) days after the date such post-effective amendment or Subsequent Shelf
Registration Statement, as the case may be, is required by this Section 2(d) to be filed with the SEC; 
 (C) the
Company shall provide such Notice Holder, upon request, with a reasonable number of copies of any documents filed pursuant to clause (A) above; 
 (D) the Company shall notify such Notice Holder as promptly as practicable after the effectiveness under the Securities Act of any post-effective amendment or Subsequent Shelf Registration Statement filed pursuant to
clause (A) above; 
 (E) if such Holder became a Notice Holder during a Suspension Period, or a Suspension Period is put
into effect within five (5) Business Days after the date such Holder became a Notice Holder, the Company shall so inform such Notice Holder and shall, subject to the limitations of this Section 2(d), take the actions set forth in clauses
(A), (B) and (C) above within thirty (30) days after expiration of such Suspension Period in accordance with Section 3(j); and 
  

 - 8 - 

 (F) if, under the Securities Act, the Company has more than one option as to the type or
manner of making any such filing, the Company shall make the required filing or filings in the manner or of a type that the Company reasonably expects to result in the earliest availability of a Prospectus for effecting resales of Registrable
Securities. 
 (ii) Notwithstanding anything contained herein to the contrary, the Company shall be under no obligation to
name any Holder that is not a Notice Holder as a selling securityholder in any Shelf Registration Statement or related Prospectus; provided, however, that any Holder that becomes a Notice Holder (regardless of when such Holder became a
Notice Holder) shall be named as a selling securityholder in a Shelf Registration Statement or related Prospectus in accordance with the requirements of this Section 2(d) or Section 2(a), as applicable. 
 (e) The parties hereto agree that the Holders of Registrable Securities will suffer damages, and that it would not be feasible to
ascertain the extent of such damages with precision, if: 
 (i) the Initial Shelf Registration Statement has not become
effective under the Securities Act on or prior to the Effectiveness Deadline Date; 
 (ii) either a supplement to a
Prospectus, a post-effective amendment or a Subsequent Shelf Registration Statement is required to be filed with the SEC and fails to be filed with the SEC within the prescribed period and in the manner set forth in Section 2(d) (the date such
filing is required to be made being an “Additional Filing Deadline Date”) or, in the case of a post-effective amendment or a Subsequent Shelf Registration Statement, such post-effective amendment or Subsequent Registration Statement
does not become effective under the Securities Act by the Amendment Effectiveness Deadline Date or the Subsequent Shelf Registration Statement Effectiveness Deadline Date, as the case may be; 
 (iii) the Initial Shelf Registration Statement or any Subsequent Registration Statement is filed with the SEC and becomes effective under
the Securities Act but shall thereafter cease to be effective (without being succeeded immediately by a new Registration Statement that is filed and immediately becomes effective under the Securities Act) or usable under the Securities Act for the
offer and sale of Registrable Securities in the manner contemplated by this Agreement for a period of time (including any Suspension Period) which shall exceed forty five (45) days in the aggregate in any three (3) month period or ninety
(90) days in the aggregate in any twelve (12) month period; or 
 (iv) any Registration Statement or amendment
thereto, at the time it 
  

 - 9 - 

 becomes effective under the Securities Act, or any Prospectus relating thereto, at the time it is filed
with the SEC or, if later, at the time the Registration Statement to which such Prospectus relates becomes effective under the Securities Act, shall fail to name each Notice Holder as a selling securityholder in such a manner as to permit such
Notice Holder to sell its Registrable Securities pursuant to such Registration Statement and Prospectus in accordance with the Securities Act, which Notice Holder was required, pursuant to the terms of this Agreement, to be so named (it being
understood that, without limitation, naming such Notice Holder in a manner that permits such Notice Holder to sell only a portion of such Notice Holder’s Registrable Securities referenced in such Notice Holder’s Notice and Questionnaire
shall be deemed to be an “Event” (as defined below) for purposes of this clause (iv)). 
 Each of the events of a type described in
any of the foregoing clauses (i) through (iv) are individually referred to herein as an “Event,” and 
 (W) the Effectiveness Deadline Date, in the case of clause (i) above, 
 (X) the Additional Filing Deadline
Date, the Amendment Effectiveness Deadline Date or the Subsequent Shelf Registration Statement Effectiveness Deadline Date, as the case may be, in the case of clause (ii) above, 
 (Y) the date on which the duration of the ineffectiveness or unusability of the Shelf Registration Statement exceeds the number of days
permitted by clause (iii) above, in the case of clause (iii) above, and 
 (Z) the date the applicable Registration
Statement or amendment thereto shall become effective under the Securities Act, or the date the applicable Prospectus is filed with the SEC or, if later, the time the Registration Statement to which such Prospectus relates becomes effective under
the Securities Act, as the case may be, in the case of clause (iv) above, 
 are each herein referred to as an “Event
Date.” Events shall be deemed to continue until the following dates with respect to the respective types of Events: 
 (A) the date the Initial Shelf Registration Statement becomes effective under the Securities Act, in the case of an Event of the type described in clause (i) above; 
 (B) the date a supplement to a Prospectus, a post-effective amendment or a Subsequent Shelf Registration Statement, whichever is required,
is filed with the SEC (in the case of a supplement) or becomes effective under the Securities Act (in the case of a post-effective amendment or a Subsequent Shelf Registration Statement), in the case of an Event of the type described in clause
(ii) above; 
 (C) the date the Initial Shelf Registration Statement or the Subsequent 
  

 - 10 - 

 Shelf Registration Statement, as the case may be, becomes effective and usable under the Securities Act
again, or the date another Subsequent Shelf Registration Statement is filed with the SEC pursuant to Section 2(b) and becomes effective, in the case of an Event of the type described in clause (iii) above; or 
 (D) the date a supplement to the Prospectus is filed with the SEC, or the date a post-effective amendment to the Registration Statement
becomes effective under the Securities Act, or the date a Subsequent Shelf Registration Statement becomes effective under the Securities Act, which supplement, post-effective amendment or Subsequent Shelf Registration Statement, as the case may be,
names as selling securityholders, in such a manner as to permit them to deliver the related Prospectus to purchasers of Registrable Securities in the manner contemplated by, and in accordance with, the Securities Act, all Notice Holders required as
herein provided to be so named, in the case of an Event of the type described in clause (iv) above. 
 Notwithstanding anything herein to
the contrary, Events described in clauses (i), (ii) and (iv) above will be deemed to be suspended during any Suspension Period unless the duration of such Suspension Period exceeds forty five (45) days in the aggregate in any three
(3) month period or ninety (90) days in the aggregate in any twelve (12) month period. 
 Accordingly, commencing on (and
including) any Event Date and ending on (but excluding) the next date on which there are no Events that have occurred and are continuing (an “Additional Interest Accrual Period”), the Company agrees to pay, as additional interest
(“additional interest”) and not as a penalty, an amount (the “Additional Interest Amount”) at the rate described below, payable semi-annually on each Additional Interest Payment Date to Record Holders, to the extent
of, for each such Additional Interest Payment Date, the unpaid Additional Interest Amount that has accrued to (but excluding) such Additional Interest Payment Date (or, if the Additional Interest Accrual Period shall have ended prior to such
Additional Interest Payment Date, to, but excluding, the day immediately after the last day of such Additional Interest Accrual Period); provided, however, that any unpaid Additional Interest Amount that has accrued with respect to any
Note, or portion thereof, called for Redemption on a Redemption Date, or purchased by the Company pursuant to a Repurchase at Holder’s Option or Repurchase Upon Repurchase Event on an Option Purchase Date or Repurchase Date, as the case may be,
that is after the close of business on the Record Date relating to such Additional Interest Payment Date and before such Additional Interest Payment Date, shall, in each case, be instead paid, on such Redemption Date, Option Purchase Date or
Repurchase Date, as the case may be, to the Holder who submitted such Note or portion thereof for Redemption, Repurchase at Holder’s Option or Repurchase Upon Repurchase Event, as the case may be. 
 The Additional Interest Amount shall accrue at a rate per annum equal to one quarter of one percent (0.25%) for the ninety (90) day period beginning
on, and including, the Event Date, and thereafter at a rate per annum equal to one half of one percent (0.50%), of the aggregate principal amount of the Notes of which such Record Holders were holders of record at the close of business on the
applicable Record Date; provided, however, that: 
 (I) no Additional Interest Amounts shall accrue as to any
Covered Security from and after the earlier of (x) the date such Covered Security is no longer a Registrable Security, (y) in the case of a Covered Security that is a Note, the date, and to the extent, such Note is converted into cash and,
if applicable, shares of Common Stock in accordance with the Indenture and (z) the expiration of the Effectiveness Period; 
  

 - 11 - 

 (II) only those Holders (or their subsequent transferees) failing to be named as selling
securityholders in the manner prescribed in Section 2(e)(iv) above shall be entitled to receive any Additional Interest Amounts that have accrued solely with respect to an Event of the type described in Section 2(e)(iv) above (it being
understood that this clause (II) shall not impair any right of any Holder to receive Additional Interest Amounts that have accrued with respect to an Event other than an Event of the type described in Section 2(e)(iv) above); 
 (III) only those Holders (or their subsequent transferees) whose delivery of a Notice and Questionnaire gave rise to the obligation of the
Company, pursuant to Section 2(d)(i), to file and, if applicable, make effective under the Securities Act the supplement, post-effective amendment or Subsequent Shelf Registration Statement referred to in Section 2(e)(ii) above shall be
entitled to receive any Additional Interest Amounts that have accrued solely with respect to an Event of the type described in Section 2(e)(ii) above (it being understood that this clause (III) shall not impair any right of any Holder to
receive Additional Interest Amounts that have accrued with respect to an Event other than an Event of the type described in Section 2(e)(ii) above); and 
 (IV) if a Covered Security ceases to be outstanding during an Additional Interest Accrual Period for which an Additional Interest Amount
would be payable with respect to such Covered Security, then the Additional Interest Amount payable hereunder with respect to such Covered Security shall be prorated on the basis of the number of full days such Covered Security is outstanding during
such Additional Interest Accrual Period. 
 Except as provided in the final paragraph of this Section 2(e), (i) the rate of accrual
of the Additional Interest Amount with respect to any period shall not exceed the rate provided for in this Section 2(e) notwithstanding the occurrence of multiple concurrent Events and (ii) following the cure of all Events requiring the
payment by the Company of Additional Interest Amounts to the Holders pursuant to this Section, the accrual of Additional Interest Amounts shall cease (without in any way limiting the effect of any subsequent Event requiring the payment of Additional
Interest Amounts by the Company). All installments of additional interest shall be paid by wire transfer of immediately available funds to the account specified by the Notice Holder or, if no such account is specified, by mailing a check to such
Notice Holder’s address shown in the register of the registrar for 
  

 - 12 - 

 the Notes or for the Underlying Common Stock, as the case may be. Subject to any rights that may arise
under Section 6, the parties hereto agree that the additional interest provided for hereunder shall constitute the sole and exclusive remedy for an Event that occurs with respect to any Note or with respect to any shares of Common Stock that
both underlie such Note and are not outstanding, provided, however, that nothing in this sentence shall affect the rights hereunder of a holder of outstanding Underlying Common Stock. 
 All of the Company’s obligations set forth in this Section 2(e) that are outstanding with respect to any Registrable Security at the time such
Registrable Security ceases to be a Registrable Security shall survive until such time as all such obligations with respect to such security have been satisfied in full (notwithstanding termination of this Agreement pursuant to Section 9(n)).

 The parties hereto agree that the additional interest provided for in this Section 2(e) constitutes a reasonable estimate of the
damages in respect of the Notes that may be incurred by Holders of the Notes by reason of an Event relating to such Notes, including, without limitation, the failure of a Shelf Registration Statement to be filed, become effective under the
Securities Act, amended or replaced to include the names of all Notice Holders or available for effecting resales of Registrable Securities in accordance with the provisions hereof. 
 If any Additional Interest Amounts are not paid when due, then, to the extent permitted by law, such overdue Additional Interest Amounts, if any, shall
bear interest, compounded semi-annually, until paid at the rate of interest payable with respect to overdue amounts on the Notes pursuant to Section 2.12 of the Indenture. 
 (f) The Trustee shall be entitled, on behalf of Holders, to seek any available remedy for the enforcement of this Agreement, including for
the payment of any Additional Interest Amount. 
 3. Registration Procedures. In connection with the registration obligations of the
Company under Section 2 hereof, the Company shall: 
 (a) Prepare and file with the SEC a Shelf Registration Statement or
Shelf Registration Statements in the manner provided in this Agreement and use its reasonable best efforts to cause each such Shelf Registration Statement to become effective under the Securities Act and remain effective under the Securities Act as
provided herein; provided, that, before filing any Shelf Registration Statement or Prospectus or any amendments or supplements thereto with the SEC, the Company shall furnish to the Initial Purchasers, Designated Counsel, if any, and counsel
for the Initial Purchasers copies of all such documents proposed to be filed and give reasonable consideration to any comments as the Initial Purchasers, Designated Counsel, if any, or such counsel shall propose within two (2) Business Days of
the delivery of such copies to the Initial Purchasers, Designated Counsel, if any, and such counsel. Each Registration Statement that is or is required by this Agreement to be filed with the SEC shall be filed on Form S-3 
  

 - 13 - 

 if the Company is then eligible to use Form S-3 for the purposes contemplated by this Agreement, or, if
the Company is not then so eligible to use Form S-3, shall be on Form S-1 or another appropriate form that is then available to the Company for the purposes contemplated by this Agreement. Each such Registration Statement that is filed on Form S-3
shall constitute an Automatic Shelf Registration Statement if the Company is then eligible to file an Automatic Shelf Registration Statement on Form S-3 for the purposes contemplated by this Agreement. If, at the time any Registration Statement is
filed with the SEC, the Company is eligible, pursuant to Rule 430B(b), to omit, from the prospectus that is filed as part of such Registration Statement, the identities of selling securityholders and amounts of securities to be registered on their
behalf, then the Company shall prepare and file such Registration Statement in a manner as to permit such omission and to allow for the subsequent filing of such information in a prospectus pursuant to Rule 424(b) in the manner contemplated by Rule
430B(d). 
 (b) Prepare and file with the SEC such amendments and post-effective amendments to each Shelf Registration
Statement as may be necessary to keep such Shelf Registration Statement or Subsequent Shelf Registration Statement continuously effective until the expiration of the Effectiveness Period (except to the extent permitted under Section 3(j));
cause the related Prospectus to be supplemented by any required Prospectus supplement and, as so supplemented, to be filed with the SEC pursuant to Rule 424; and comply with the provisions of the Securities Act applicable to it with respect to the
disposition of all securities covered by each Shelf Registration Statement during the Effectiveness Period (except to the extent permitted under Section 3(j)) in accordance with the intended methods of disposition by the sellers thereof set
forth in such Shelf Registration Statement as so amended or such Prospectus as so supplemented. 
 (c) If, at any time during
the Effectiveness Period, any Registration Statement shall cease to comply with the requirements of the Securities Act with respect to eligibility for the use of the form on which such Registration Statement was filed with the SEC (or if such
Registration Statement constituted an Automatic Shelf Registration Statement at the time it was filed with the SEC and shall thereafter cease to constitute an Automatic Shelf Registration Statement, or if the Company shall have received, from the
SEC, a notice, pursuant to Rule 401(g)(2) under the Securities Act, of objection to the use of the form on which such Registration Statement was filed with the SEC), (i) promptly give notice to the Notice Holders, Designated Counsel, if any,
and counsel for the Initial Purchasers and to the Initial Purchasers and (ii) promptly file with the SEC a new Registration Statement under the Securities Act, or a post-effective amendment to such Registration Statement, to effect compliance
with the Securities Act. The Company shall use its reasonable best efforts to cause such new Registration Statement or post-effective amendment to become effective under the Securities Act as soon as practicable and shall promptly give notice of
such effectiveness to the Notice Holders, Designated Counsel, if any, and counsel for the Initial Purchasers and to the Initial Purchasers. Each such new Registration Statement, if any, shall be deemed, for purposes of this Agreement, to be a
Subsequent Shelf Registration Statement. 
  

 - 14 - 

 (d) During the Effectiveness Period, as promptly as practicable, give notice to the
Notice Holders, the Initial Purchasers, Designated Counsel, if any, and counsel for the Initial Purchasers: 
 (i) when any
Prospectus, Prospectus supplement, Shelf Registration Statement or post-effective amendment to a Shelf Registration Statement has been filed with the SEC and, with respect to a Shelf Registration Statement or any post-effective amendment, when the
same has become effective under the Securities Act, 
 (ii) of any request, following the effectiveness of a Shelf
Registration Statement under the Securities Act, by the SEC or any other governmental authority for amendments or supplements to such Shelf Registration Statement or the related Prospectus or for additional information, 
 (iii) of the issuance by the SEC or any other governmental authority of any stop order suspending the effectiveness of any Shelf
Registration Statement or the initiation or threatening of any proceedings for that purpose, 
 (iv) of the receipt by the
Company or its legal counsel of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding
for such purpose, 
 (v) after the effective date of any Shelf Registration Statement filed with the SEC pursuant to this
Agreement, of the occurrence of (but not the nature of or details concerning) a Material Event, and 
 (vi) of the
determination by the Company that a post-effective amendment to a Shelf Registration Statement or a Subsequent Shelf Registration Statement will be filed with the SEC, which notice may, at the discretion of the Company (or as required pursuant to
Section 3(j)), state that it constitutes a Suspension Notice, in which event the provisions of Section 3(j) shall apply. 
 (e) Subject to the terms hereof, use its reasonable best efforts to (i) prevent the issuance of, and, if issued, to obtain the withdrawal of, any order suspending the effectiveness of a Shelf Registration Statement and (ii) obtain
the lifting of any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction in which they have been qualified for sale, in either case at the earliest possible moment, and
provide prompt notice to each Notice Holder, the Initial Purchasers, Designated Counsel, if any, and counsel for the Initial Purchasers, of the withdrawal or lifting of any such order or suspension. 
 (f) Give reasonable consideration to any written request by the Initial Purchasers or any Notice Holder, to incorporate in a Prospectus
supplement or a post-effective amendment to a Shelf Registration Statement such information as the Initial Purchasers, such Notice Holder, Designated Counsel, if any, or counsel for the Initial 
  

 - 15 - 

 Purchasers shall have determined to be required to be included therein by applicable U.S. law and, if the
Company determines pursuant hereto to give effect to such request, to make any required filings of such Prospectus supplement or such post-effective amendment as promptly as practicable. 
 (g) As promptly as practicable, furnish, upon request, to each Notice Holder, Designated Counsel, if any, the Initial Purchasers and
counsel for the Initial Purchasers, without charge, at least one (1) conformed copy of each Shelf Registration Statement and each amendment thereto, including financial statements but excluding schedules, all documents incorporated or deemed to
be incorporated therein by reference and all exhibits (unless requested in writing to the Company by such Notice Holder, Designated Counsel, such counsel or the Initial Purchasers). 
 (h) During the Effectiveness Period, deliver to each Notice Holder, Designated Counsel, if any, the Initial Purchasers and counsel for the
Initial Purchasers, in connection with any sale of Registrable Securities pursuant to a Shelf Registration Statement, without charge, as many copies of the Prospectus or Prospectuses relating to such Registrable Securities and any amendment or
supplement thereto as such Notice Holder or the Initial Purchasers may reasonably request; and the Company hereby consents (except during such periods that a Suspension Notice is outstanding and has not been revoked) to the use of such Prospectus
and each amendment or supplement thereto by each Notice Holder, in connection with any offering and sale of the Registrable Securities covered by such Prospectus or any amendment or supplement thereto in the manner set forth therein. 
 (i) Prior to any public offering of the Registrable Securities pursuant to a Shelf Registration Statement, use its reasonable best efforts
to register or qualify or cooperate with the Notice Holders in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities for offer and sale under the securities or Blue
Sky laws of such jurisdictions within the United States as any Notice Holder reasonably requests in writing (which request may be included in the Notice and Questionnaire); use its reasonable best efforts to keep each such registration or
qualification (or exemption therefrom) effective during the Effectiveness Period in connection with such Notice Holder’s offer and sale of Registrable Securities pursuant to such registration or qualification (or exemption therefrom) and do any
and all other acts or things reasonably necessary or advisable to enable the disposition in such jurisdictions of such Registrable Securities in the manner set forth in the relevant Shelf Registration Statement and the related Prospectus;
provided, however, that the Company will not be required to (i) qualify generally to do business in any jurisdiction where it is not then so qualified or (ii) take any action that would subject it to general service of
process in suits, other than those arising out of and limited solely to the offering or sale of Registrable Securities, in any jurisdiction where it is not now so subject. 
 (j) Upon: (A) the occurrence or existence of any pending or prospective corporate development (a “Material Event”)
that, in the reasonable discretion of the 
  

 - 16 - 

 Company, makes it appropriate to suspend the availability of any Shelf Registration Statement and the
related Prospectus; (B) the issuance by the SEC of a stop order suspending the effectiveness of any Shelf Registration Statement or the initiation of proceedings with respect to any Shelf Registration Statement under Section 8(d) or 8(e)
of the Securities Act; or (C) the occurrence of any event or the existence of any fact as a result of which any Shelf Registration Statement shall contain any untrue statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading, or any Prospectus shall contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading, 
 (i) in the case of clause (A) or (C) above, subject
to the next sentence, as promptly as practicable, prepare and file, if necessary pursuant to the Securities Act, a post-effective amendment to such Shelf Registration Statement or a supplement to such Prospectus or any document incorporated therein
by reference or file any other required document that would be incorporated by reference into such Shelf Registration Statement and Prospectus so that such Shelf Registration Statement does not contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and so that such Prospectus does not contain any untrue statement of a material fact or omit to state any material fact necessary in
order to make the statements therein, in the light of the circumstances under which they were made, not misleading, as thereafter delivered to the purchasers of the Registrable Securities being sold thereunder (it being understood that the Company
may rely on information with respect to a Notice Holder provided by such Notice Holder to the Company for use in such Prospectus, including, without limitation, the Holder Information), and, in the case of a post-effective amendment to a Shelf
Registration Statement, subject to the next sentence, use its reasonable best efforts to cause it to become effective under the Securities Act as promptly as practicable, and 
 (ii) give notice to the Notice Holders, the Initial Purchasers, Designated Counsel, if any, and counsel for the Initial Purchasers that
the availability of the Shelf Registration Statement is suspended (a “Suspension Notice”) (and, upon receipt of any Suspension Notice, each Notice Holder agrees not to sell any Registrable Securities pursuant to such Shelf
Registration Statement until such Notice Holder’s receipt of copies of the supplemented or amended Prospectus provided for in clause (i) above or until such Notice Holder is advised in writing by the Company that the Prospectus may be
used). 
 The Company will use its reasonable best efforts to ensure that the use of the Prospectus may be resumed (x) in the case of
clause (A) above, as soon as, in the reasonable discretion of the Company, such suspension is no longer appropriate, (y) in the case of clause (B) above, as promptly as is practicable, and (z) in the case of clause
(C) above, as soon as, in the reasonable judgment of the Company, the Shelf Registration Statement 
  

 - 17 - 

 does not contain any untrue statement of a material fact or omit to state any material fact required to
be stated therein or necessary to make the statements therein not misleading and the Prospectus does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading. The period during which the availability of the Shelf Registration Statement and any Prospectus may be suspended (the “Suspension Period”) without the Company
incurring any obligation to pay additional interest pursuant to Section 2(e) shall not exceed forty five (45) days in the aggregate in any three (3) month period or ninety (90) days in the aggregate in any twelve (12) month
period. 
 (k) Make available for inspection during normal business hours by representatives for the Notice Holders (and any
underwriters participating in any disposition pursuant to any Shelf Registration Statement to the extent permitted hereunder) and any broker-dealers, attorneys and accountants retained by such Notice Holders (or any such underwriters, if
applicable), all relevant financial and other records and pertinent corporate documents and properties of the Company and its subsidiaries, and cause the appropriate officers, directors and employees of the Company and its subsidiaries to make
available for inspection during normal business hours all relevant information reasonably requested by such representatives for the Notice Holders, or any such underwriters, broker-dealers, attorneys or accountants in connection with such
disposition, in each case as is customary for similar “due diligence” examinations; provided, however, that such persons shall first agree in writing with the Company that such person will not engage in any transaction
involving Company securities in violation of applicable law (including without limitation federal securities laws prohibiting trading on the basis of material non-public information) and that any information that is confidential at the time of
delivery of such information shall be kept confidential by such persons and shall be used solely for the purposes of exercising rights under this Agreement, unless (i) disclosure of such information is required by court or administrative order
or is necessary to respond to inquiries of governmental or regulatory authorities, (ii) disclosure of such information is required by law (including any disclosure requirements pursuant to federal securities laws in connection with the filing
of any Shelf Registration Statement or the use of any Prospectus referred to in this Agreement) or necessary to defend or prosecute a claim brought against or by any such persons (e.g., to establish a “due diligence” defense),
(iii) such information becomes generally available to the public other than as a result of a disclosure or failure to safeguard by any such person or (iv) such information becomes available to any such person from a source other than the
Company and such source is not bound by a confidentiality agreement or is not otherwise under a duty of trust to the Company; provided further, that the foregoing inspection and information gathering shall, to the greatest extent
possible, be coordinated on behalf of all the Notice Holders and the other parties entitled thereto by Designated Counsel. 
 (l) Comply with all applicable rules and regulations of the SEC to the extent and so long as they are applicable to any Shelf Registration Statement; and make generally available to its securityholders earnings statements (which need not be
audited) 
  

 - 18 - 

 satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any
similar rule promulgated under the Securities Act), which statements shall cover a period of twelve (12) months commencing on the first day of the first fiscal quarter of the Company commencing after the effective date of each Shelf
Registration Statement (within the meaning of Rule 158(c) under the Securities Act), and which statements shall be so made generally available to the Company’s securityholders as follows: (i) with respect to an earnings statement which
will be contained in one report on Form 10-K (or any other form as may then be available for such purpose), such earnings statement shall be made so generally available no later than the due date by which the Company is required, pursuant to the
Exchange Act, to file such report with the SEC; and (ii) with respect to an earnings statement which will be contained in any combination of reports on Form 10-K or Form 10-Q (or any other form(s) as may then be available for such purpose),
such earnings statement shall be made so generally available no later than the due date by which the Company is required, pursuant to the Exchange Act, to file the last of such reports which together constitute such earnings statement. 

(m) Cooperate with each Notice Holder to facilitate the timely preparation and delivery of certificates representing Registrable
Securities sold pursuant to a Shelf Registration Statement, which certificates shall not bear any restrictive legends, and cause such Registrable Securities to be in such denominations as are permitted by the Indenture and registered in such names
as such Notice Holder may request in writing at least two (2) Business Days prior to any sale of such Registrable Securities. 
 (n) Provide a CUSIP number for all Registrable Securities covered by a Shelf Registration Statement not later than the effective date of the Initial Shelf Registration Statement and provide the Trustee and the transfer agent for the Common
Stock with certificates for the Registrable Securities that are in a form eligible for deposit with The Depository Trust Company. 
 (o) Cooperate and assist in any filings required to be made with the National Association of Securities Dealers, Inc. 
 (p) Upon the filing of the Initial Shelf Registration Statement, and upon the effectiveness under the Securities Act of the Initial Shelf Registration Statement, announce the same, in each case by release through a reputable national
newswire service. 
 (q) Except as otherwise provided herein, take all actions as are necessary, or reasonably requested by
the Holders of a majority of the Registrable Securities being sold, in order to expedite or facilitate disposition of the Registrable Securities. 
 (r) Cause the Indenture to be qualified under the TIA not later than the effective date of the Initial Shelf Registration Statement; and, in connection therewith, cooperate with the Trustee to effect such changes to
the Indenture as may be required for the Indenture to be so qualified in accordance with the terms of the TIA and execute, and use its reasonable best efforts to cause the Trustee to execute, all documents as may be required to effect such changes,
and all other forms and documents required to be filed with the SEC to enable the Indenture to be so qualified in a timely manner.

 (s) Use its reasonable best efforts to cause the Underlying Common Stock to be listed on
The New York Stock Exchange. 
 4. Holder’s Obligations. Each Holder agrees, by acquisition of the Registrable Securities, that
no Holder of Registrable Securities shall be entitled to sell any of such Registrable Securities pursuant to a Shelf Registration Statement or to receive a Prospectus relating thereto, unless such Holder has furnished the Company with a Notice and
Questionnaire as required pursuant to Section 2(d) hereof (including the information required to be included in such Notice and Questionnaire) and the information set forth in the next sentence. Each Notice Holder agrees promptly to furnish to
the Company all information required to be disclosed in order to make the information previously furnished to the Company by such Notice Holder not misleading and any other information regarding such Notice Holder and the distribution of such
Registrable Securities as the Company may from time to time reasonably request. Any sale of any Registrable Securities by any Holder shall constitute a representation and warranty by such Holder that, as of the time of such sale, the Holder
Information of such Holder furnished in writing by or on behalf of such Holder to the Company does not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements in such Holder
Information, in the light of the circumstances under which they were made, not misleading. Each Holder agrees to keep confidential the receipt of any Suspension Notice and the contents thereof, except as required pursuant to applicable law.

 5. Registration Expenses. The Company shall bear all fees and expenses incurred in connection with the performance by the Company
of its obligations under Section 2 and Section 3 of this Agreement whether or not any of the Shelf Registration Statements are filed or declared effective under the Securities Act. Such fees and expenses (“Registration
Expenses”) shall include, without limitation, (i) all registration and filing fees and expenses (including, without limitation, fees and expenses (x) with respect to filings required to be made with the National Association of
Securities Dealers, Inc. and (y) of compliance with federal securities laws and state securities or Blue Sky laws (including, without limitation, reasonable fees and disbursements of Designated Counsel, if any, in connection with Blue Sky
qualifications of the Registrable Securities under the laws of such jurisdictions, (ii) all printing expenses (including, without limitation, expenses of printing certificates for Registrable Securities in a form eligible for deposit with The
Depository Trust Company and printing Prospectuses), (iii) all duplication and mailing expenses relating to copies of any Shelf Registration Statement or Prospectus delivered to any Holders hereunder, (iv) all fees and disbursements of
counsel for the Company, (v) all fees and disbursements of Designated Counsel (provided, however, that in no event shall the Company be obligated to pay hereunder any such fees and disbursements to the extent they exceed fifteen
thousand dollars ($15,000) in the aggregate), (v) all fees and disbursements of the Trustee and its counsel and of the registrar and transfer agent for the Common Stock and (vi) Securities Act liability insurance obtained by the Company in
its sole discretion. In addition, the Company shall pay the internal expenses of the Company (including, without limitation, all salaries and expenses of officers and employees performing legal or accounting duties), the expense of any annual audit
or quarterly review, the fees and expenses incurred in connection 
  

 - 20 - 

 with the listing by the Company of the Registrable Securities on any securities exchange or quotation system on which
similar securities of the Company are then listed and the fees and expenses of any person, including, without limitation, special experts, retained by the Company. If the Company shall, pursuant to Rule 456(b), defer payment of any registration fees
due under the Securities Act with respect to any Registration Statement, the Company agrees that it shall pay the fees applicable to such Registration Statement within the time required by Rule 456(b)(1)(i) (without reliance on the proviso to Rule
456(b)(1)(i)) and in compliance with Rule 456(b) and Rule 457(r). Except as provided above, each Holder shall pay all brokerage fees and commissions incurred by it, all transfer taxes incurred by it, the fees and expenses of any advisors the Holder
engages and all similar fees and costs incurred by such Holder relating to such Holder’s disposition of Registrable Securities. 
 6.
Indemnification, Contribution. 
 (a) The Company agrees to indemnify, defend and hold harmless each Initial Purchaser,
each Holder, each person (a “Controlling Person”), if any, who controls any Initial Purchaser or Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and the respective officers,
directors, partners, employees, representatives and agents of any Initial Purchaser, the Holders or any Controlling Person (each, an “Indemnified Party”), from and against any loss, damage, expense, liability, claim or any actions
in respect thereof (including the reasonable cost of investigation) which such Indemnified Party may incur or become subject to under the Securities Act, the Exchange Act or otherwise, insofar as such loss, damage, expense, liability, claim or
action arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in any Shelf Registration Statement or Prospectus, including any document incorporated by reference therein, or in any amendment or
supplement thereto or in any preliminary prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact required to be stated in any Shelf Registration Statement or in any amendment or supplement thereto or
necessary to make the statements therein not misleading, or arises out of or is based upon any omission or alleged omission to state a material fact necessary in order to make the statements made in any Prospectus or in any amendment or supplement
thereto or in any preliminary prospectus, in the light of the circumstances under which such statements were made, not misleading, and the Company shall reimburse, as incurred, the Indemnified Parties for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss, damage, expense, liability, claim or action in respect thereof; provided, however, that the Company shall not be required to provide any indemnification
pursuant to this Section 6(a) in any such case insofar as any such loss, damage, expense, liability, claim or action arises out of or is based upon any untrue statement or omission or alleged untrue statement or omission of a material fact
contained in, or omitted from, and in conformity with information furnished in writing by or on behalf of an Initial Purchaser or a Holder to the Company expressly for use in, any Shelf Registration Statement or any Prospectus, including, without
limitation, information provided to the Company by such Holder in a Notice and Questionnaire; provided further, however, that this indemnity agreement will be in addition to any liability which the Company may otherwise have to
such Indemnified 
  

 - 21 - 

 Party; provided further, however, that no Initial Purchaser or Holder shall be
entitled to this indemnity to the extent, and only to the extent, such loss, damage, expense, liability, claim or action arises out of a disposition, pursuant to a Shelf Registration Statement, of Registrable Securities by such Initial Purchaser or
Holder, as the case may be, during a Suspension Period, provided such Initial Purchaser or Holder, as the case may be, received, prior to such disposition, a Suspension Notice with respect to such Suspension Period. 
 (b) Each Holder, severally and not jointly, agrees to indemnify, defend and hold harmless the Company, its directors, officers, employees,
representatives and agents and any person who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each, a “Company Indemnified Party”) from and against any loss,
damage, expense, liability, claim or any actions in respect thereof (including the reasonable cost of investigation) which such Company Indemnified Party may incur or become subject to under the Securities Act, the Exchange Act or otherwise, insofar
as such loss, damage, expense, liability, claim or action arises out of or is based upon (A) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information (the “Holder
Information”) furnished in writing by or on behalf of such Holder to the Company expressly for use in, any Shelf Registration Statement or Prospectus, or arises out of or is based upon any omission or alleged omission to state a material
fact in connection with such Holder Information, which material fact was not contained in such Holder Information, and which material fact was either required to be stated in any Shelf Registration Statement or Prospectus, or any amendment or
supplement thereto, or necessary to make such Holder Information not misleading; (B) a sale, by such Holder, pursuant to a Shelf Registration Statement, of Registrable Securities during a Suspension Period, provided that the Company shall have
theretofore provided such Holder with a Suspension Notice with respect to such Suspension Period; or (C) a public sale of Registrable Securities by such Holder without delivery, if required by the Securities Act, of the most recent applicable
Prospectus provided to such Holder by the Company pursuant to Section 3(h) or Section 2(d)(i)(C); and, subject to the limitation set forth in the immediately preceding clause, each Holder shall reimburse, as incurred, the Company for any
legal or other expenses reasonably incurred by the Company or any such controlling person in connection with investigating or defending any loss, damage, expense, liability, claim or action in respect thereof. This indemnity agreement will be in
addition to any liability which such Holder may otherwise have to the Company or any of its controlling persons. In no event shall the liability of any selling Holder of Registrable Securities hereunder be greater in amount than the dollar amount of
the proceeds received by such Holder upon the sale, pursuant to the Shelf Registration Statement, of the Registrable Securities giving rise to such indemnification obligation. 
 (c) If any action, suit or proceeding (each, a “Proceeding”) is brought against any person in respect of which indemnity
may be sought pursuant to either Section 6(a) or Section 6(b), such person (the “Indemnified Party”) shall promptly notify the person against whom such indemnity may be sought (the “Indemnifying Party”) in
writing of the institution of such Proceeding and the Indemnifying Party shall assume the defense of 
  

 - 22 - 

 such Proceeding; provided, however, that the omission to so notify such Indemnifying Party
shall not relieve such Indemnifying Party from any liability which it may have to such Indemnified Party or otherwise, except to the extent such Indemnifying Party is materially prejudiced by such omission. Such Indemnified Party shall have the
right to employ its own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless the employment of such counsel shall have been authorized in writing by such Indemnifying Party in
connection with the defense of such Proceeding or such Indemnifying Party shall not have employed counsel to have charge of the defense of such Proceeding within thirty (30) days of the receipt of notice thereof or such Indemnified Party shall
have reasonably concluded upon the written advice of counsel that there may be one or more defenses available to it that are different from, additional to or in conflict with those available to such Indemnifying Party (in which case such
Indemnifying Party shall not have the right to direct that portion of the defense of such Proceeding on behalf of the Indemnified Party, but such Indemnifying Party may employ counsel and participate in the defense thereof but the fees and expenses
of such counsel shall be at the expense of such Indemnifying Party), in any of which events such reasonable fees and expenses shall be borne by such Indemnifying Party and paid as incurred (it being understood, however, that such Indemnifying Party
shall not be liable for the expenses of more than one separate counsel in any one Proceeding or series of related Proceedings together with reasonably necessary local counsel representing the Indemnified Parties who are parties to such action). An
Indemnifying Party shall not be liable for any settlement of such Proceeding effected without the written consent of such Indemnifying Party, but if settled with the written consent of such Indemnifying Party, such Indemnifying Party agrees to
indemnify and hold harmless an Indemnified Party from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an Indemnified Party shall have requested an Indemnifying Party to reimburse
such Indemnified Party for fees and expenses of counsel as contemplated by the second sentence of this paragraph, then such Indemnifying Party agrees that it shall be liable for any settlement of any Proceeding effected without its written consent
if (i) such settlement is entered into more than sixty (60) Business Days after receipt by such Indemnifying Party of the aforesaid request, (ii) such Indemnifying Party shall not have fully reimbursed such Indemnified Party in
accordance with such request prior to the date of such settlement or shall not have, prior to the date of such settlement, reimbursed such Indemnified Party for the portion of such requested amount as the Indemnifying Party believes in good faith to
be reasonable (provided such Indemnifying Party has theretofore provided written notice to such Indemnified Party that the Indemnifying Party disputes in good faith the reasonableness of the unpaid balance) and (iii) such Indemnified Party
shall have given such Indemnifying Party at least thirty (30) days’ prior notice of its intention to settle. No Indemnifying Party shall, without the prior written consent of any Indemnified Party, effect any settlement of any pending or
threatened Proceeding in respect of which such Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified
Party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault or culpability or a failure to act by or on behalf of such Indemnified Party. 
  

 - 23 - 

 (d) If the indemnification provided for in this Section 6 is unavailable to an
Indemnified Party under Section 6(a) or Section 6(b), or insufficient to hold such Indemnified Party harmless, in respect of any losses, damages, expenses, liabilities, claims or actions referred to therein (other than as a result of the
limitations on indemnification specified therein), then each applicable Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, damages,
expenses, liabilities, claims or actions (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and by the Holders or the Initial Purchasers, on the other hand, from the offering of
the Registrable Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but
also the relative fault of the Company, on the one hand, and of the Holders or the Initial Purchasers, on the other hand, in connection with the statements or omissions which resulted in such losses, damages, expenses, liabilities, claims or
actions, as well as any other relevant equitable considerations. The relative fault of the Company, on the one hand, and of the Holders or the Initial Purchasers, on the other hand, shall be determined by reference to, among other things, whether
the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Company or by the Holders or the Initial Purchasers and the parties’ relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, damages, expenses, liabilities, claims and actions referred to above shall be deemed to include any
reasonable legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any Proceeding. 
 (e) The Company, the Holders and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 6 were determined by pro rata allocation or by any other method of
allocation which does not take account of the equitable considerations referred to in Section 6(d) above. Notwithstanding the provisions of this Section 6, no Holder shall be required to contribute any amount in excess of the amount by
which the total price at which the Registrable Securities giving rise to such contribution obligation and sold by such Holder were offered to the public exceeds the amount of any damages which it has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The Holders’ respective obligations to contribute pursuant to this Section 6 are several in proportion to the respective amount of Registrable Securities they have sold pursuant to a Shelf
Registration Statement, and not joint. The remedies provided for in this Section 6 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity. 
 (f) The indemnity and contribution provisions contained in this Section 6 
  

 - 24 - 

 shall remain operative and in full force and effect regardless of (i) any termination of this
Agreement, (ii) any investigation made by or on behalf of any Holder or the Initial Purchasers or any person controlling any Holder or Initial Purchaser, or the Company, or the Company’s officers or directors or any person controlling the
Company and (iii) the sale of any Registrable Security by any Holder. 
 7. Information Requirements. 
 (a) The Company covenants that, if at any time before the end of the Effectiveness Period it is not subject to the reporting requirements
of the Exchange Act, it will cooperate with any Holder of Registrable Securities and take such further action as any Holder of Registrable Securities may reasonably request in writing (including, without limitation, making such representations as
any such Holder may reasonably request), all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitations of the exemptions provided by Rule 144,
Rule 144A or Regulation S under the Securities Act and customarily taken in connection with sales pursuant to such exemptions. Upon the written request of any Holder, the Company shall deliver to such Holder a written statement as to whether the
Company has duly filed all reports required to be filed by it under Section 13 or 15(d) the Exchange Act during the preceding twelve (12) months, unless such a statement has been included in the Company’s most recent report filed with
the SEC pursuant to Section 13 or Section 15(d) of Exchange Act. 
 (b) During the Effectiveness Period, the Company
shall use its commercially reasonable efforts to comply with all requirements set forth in the instructions to Form S-3 in order to allow the Company to be eligible to file registration statements on Form S-3. The Company shall use its commercially
reasonable efforts to remain eligible, pursuant to Rule 430B(b), to omit, from the prospectus that is filed as part of a Registration Statement, the identities of selling securityholders and amounts of securities to be registered on their behalf.

 8. Underwritten Registrations. 
 Notwithstanding anything herein to the contrary, in no event shall Registrable Securities be offered and sold pursuant hereto through a Shelf Registration Statement pursuant to an underwritten offering without the prior written agreement of
the Company. No person may participate in any underwritten registration hereunder unless such person (i) agrees to sell such person’s Registrable Securities on the basis reasonably provided in any underwriting arrangements approved by the
Company and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements. 
 9. Miscellaneous. 
 (a) Remedies. The Company acknowledges and agrees that any failure by the Company to comply with its obligations under this Agreement may result in material 
  

 - 25 - 

 irreparable injury to the Initial Purchasers and the Holders for which there is no adequate remedy at
law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, any Initial Purchaser or Holder may obtain such relief as may be required to specifically enforce the Company’s
obligations under this Agreement. The Company further agrees to waive the defense in any action for specific performance that a remedy at law would be adequate. Notwithstanding the foregoing two sentences, this Section 9(a) shall not apply to
the subject matter referred to in and contemplated by Section 2(e). 
 (b) No Conflicting Agreements. The Company
is not, as of the date hereof, a party to, nor shall it, on or after the date of this Agreement, enter into, any agreement with respect to the Company’s securities that conflicts with the rights granted to the Holders in this Agreement. The
Company represents and warrants that the rights granted to the Holders hereunder are not in conflict with the rights granted to the holders of the Company’s securities under any other agreements. The Company represents and covenants that it has
not granted, and shall not during the Effectiveness Period grant, to any of its securityholders (other than the Holders in such capacity) the right to include any of the Company’s securities in any Shelf Registration Statement filed pursuant to
this Agreement. 
 (c) Amendments and Waivers. The provisions of this Agreement, including the provisions of this
sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the Company has obtained the written consent of Holders of a majority of outstanding Registrable
Securities; provided, however, that, no consent is necessary from any of the Holders in the event that this Agreement is amended, modified or supplemented for the purpose of curing any ambiguity, defect or inconsistency that does not
adversely affect the rights of any Holders. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders of Registrable Securities whose securities
are being sold pursuant to a Shelf Registration Statement and that does not directly or indirectly affect the rights of other Holders of Registrable Securities may be given by Holders of at least a majority of the Registrable Securities being sold
by such Holders pursuant to such Shelf Registration Statement; provided, however, that the provisions of this sentence may not be amended, modified, or supplemented except in accordance with the provisions of the immediately preceding
sentence. Each Holder of Registrable Securities outstanding at the time of any such amendment, modification, supplement, waiver or consent or thereafter shall be bound by any such amendment, modification, supplement, waiver or consent effected
pursuant to this Section 9(c), whether or not any notice, writing or marking indicating such amendment, modification, supplement, waiver or consent appears on the Registrable Securities or is delivered to such Holder. 
 (d) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand delivery, by
telecopier, by courier guaranteeing overnight delivery or by first-class mail, return receipt requested, and shall be deemed given (A) when made, if made by hand delivery, (B) upon confirmation, if

 (e) Majority of Registrable Securities. For purposes of determining what constitutes holders of a majority of Registrable
Securities, as referred to in this Agreement, a majority shall constitute a majority in aggregate principal amount of Registrable Securities, treating each relevant holder of shares of Underlying Common Stock as a holder of the aggregate principal
amount of Notes in respect of which such Underlying Common Stock was issued. 
  

 - 27 - 

 (f) Approval of Holders. Whenever the consent or approval of Holders of a
specified percentage of Registrable Securities is required hereunder, Registrable Securities held by the Company or its “affiliates” (as such term is defined in Rule 405 under the Securities Act) (other than the Initial Purchasers or
subsequent Holders of Registrable Securities, if the Initial Purchasers or such subsequent Holders are deemed to be such affiliates solely by reason of their holdings of such Registrable Securities) shall not be counted in determining whether such
consent or approval was given by the Holders of such required percentage. 
 (g) Third Party Beneficiaries. Each Holder
shall be third party beneficiary to the agreements made hereunder between the Company, on the one hand, and the Initial Purchasers, on the other hand, and shall have the right to enforce such agreements directly to the extent it may deem such
enforcement necessary or advisable to protect its rights hereunder. The Trustee shall be entitled to the rights granted to it pursuant to this Agreement and shall be bound by the terms hereof. 
 (h) Successors and Assigns. Any person who purchases any Covered Security from any Initial Purchaser or from any Holder shall be
deemed, for purposes of this Agreement, to be an assignee of such Initial Purchaser or such Holder, as the case may be. This Agreement shall inure to the benefit of and be binding upon the respective successors and assigns of each of the parties
hereto and shall inure to the benefit of and be binding upon each Holder of any Covered Security. 
 (i) Counterparts.
This Agreement may be executed in any number of counterparts and by the parties hereto in separate counterparts, each of which when so executed shall be deemed to be original and all of which taken together shall constitute one and the same
agreement. 
 (j) Headings. The headings in this Agreement are for convenience of reference only and shall not
limit or otherwise affect the meaning hereof. 
 (k) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES THEREOF. 
 (l)
Severability. If any term, provision, covenant or restriction of this Agreement is held to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full
force and effect and shall in no way be affected, impaired or invalidated thereby, and the parties hereto shall use their reasonable best efforts to find and employ an alternative means to achieve the same or substantially the same result as that
contemplated by such term, provision, covenant or restriction, it being intended that all of the rights and privileges of the parties shall be enforceable to the fullest extent permitted by law. 
  

 - 28 - 

 (m) Entire Agreement. This Agreement is intended by the parties hereto as a final
expression of their agreement and is intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein and the registration rights granted by the Company with
respect to the Registrable Securities. Except as provided in the Purchase Agreement, there are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein, with respect to the registration rights granted
by the Company with respect to the Registrable Securities. This Agreement supersedes all prior agreements and undertakings among the parties with respect to such registration rights. No party hereto shall have any rights, duties or obligations other
than those specifically set forth in this Agreement. 
 (n) Termination. This Agreement and the obligations of the
parties hereunder shall terminate upon the end of the Effectiveness Period, except for any liabilities or obligations under Section 4, Section 5 or Section 6 hereof and the obligations to make payments of and provide for additional
interest under Section 2(e) hereof to the extent such additional interest accrued prior to the end of the Effectiveness Period and to the extent any overdue additional interest accrues in accordance with the last paragraph of such
Section 2(e), each of which shall remain in effect in accordance with its terms. 
 (o) Submission to
Jurisdiction. Except as set forth below, no proceeding, claim, counterclaim or dispute of any kind or nature whatsoever arising out of or in any way relating to this Agreement (“Claim”) may be commenced, prosecuted or
continued in any court other than the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, which courts shall have jurisdiction over the adjudication
of such matters, and the Company hereby consents to the jurisdiction of such courts and personal service with respect thereto. The Company hereby consents to personal jurisdiction, service and venue in any court in which any Claim arising out of or
in any way relating to this Agreement is brought by any third party against any Initial Purchaser. THE COMPANY, EACH INITIAL PURCHASER AND EACH HOLDER HEREBY WAIVES ALL RIGHTS TO TRIAL BY JURY IN ANY PROCEEDING (WHETHER BASED UPON CONTRACT, TORT OR
OTHERWISE) IN ANY WAY ARISING OUT OF OR RELATING TO THIS AGREEMENT. The Company, each Initial Purchaser and each Holder agree that a final judgment in any such Proceeding brought in any such court shall be conclusive and binding upon such party and
