attorney duly authorized in writing, at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive. 
  
 The Company shall not be required to
make, and the Registrar need not register, transfers or exchanges of Securities selected for redemption (except, in the case of Securities to be redeemed in part, the portion thereof not to be redeemed) or any Securities in respect of which a
Repurchase Notice or Fundamental Change Repurchase Notice has been given and not withdrawn by the Holder thereof in accordance with the terms of this Indenture (except, in the case of Securities to be purchased in part, the portion thereof not to be
purchased) or any Securities for a period of 15 days before the mailing of a notice of redemption of Securities to be redeemed. 
  
 (b) Notwithstanding any provision to the contrary herein, so long as a Global Security remains outstanding and is held by or on behalf of the Depositary,
transfers of a Global Security, in whole or in part, shall be made only in accordance with Section 2.12 and this Section 2.06(b). Transfers of a Global Security shall be limited to transfers of such Global Security in whole or in part, to the
Depositary, to nominees of the Depositary or to a successor of the Depositary or such successor’s nominee. 
  
 (c) Successive registrations and registrations of transfers and exchanges as aforesaid may be made from time to time as desired, and each such
registration shall be noted on the register for the Securities. 
  
 (d) Except as otherwise set forth in this Indenture, any such action taken by a Holder shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Security and of any Securities issued in exchange or
substitution therefor, irrespective of whether any notation in regard thereto is made upon such Security or any Security issued in exchange or substitution therefor. 
  

 16 

 (e) Any Registrar appointed pursuant to Section 2.03 hereof shall provide to the Trustee such information
as the Trustee may reasonably require in connection with the delivery by such Registrar of Securities upon transfer or exchange of Securities. 
  
 (f) No Registrar shall be required to make registrations of transfer or exchange of Securities during any periods designated in the text of the Securities
or in this Indenture as periods during which such registration of transfers and exchanges need not be made. 
  
 (g) If Securities are issued upon the transfer, exchange or replacement of Securities subject to restrictions on transfer and bearing the legends set
forth on the forms of Security attached hereto as Exhibits A and B setting forth such restrictions (collectively, the “Legend”), or if a request is made to remove the Legend on a Security, the Securities so issued
shall bear the Legend, or the Legend shall not be removed, as the case may be, unless there is delivered to the Company and the Registrar such satisfactory evidence, which shall include an opinion of counsel, as may be reasonably required by the
Company and the Registrar and the Trustee (if not the same Person as the Registrar), that neither the Legend nor the restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A or
Rule 144 under the Securities Act or that such Securities are not “restricted” within the meaning of Rule 144 under the Securities Act. Upon (i) provision of such satisfactory evidence, or (ii) notification by the Company to the Trustee
and Registrar of the sale of such Security pursuant to a registration statement that is effective at the time of such sale, the Trustee, at the written direction of the Company, shall authenticate and deliver a Security that does not bear the
Legend. If the Legend is removed from the face of a Security and the Security is subsequently held by the Company or an Affiliate of the Company, the Legend shall be reinstated. 
  
 Section 2.07. Replacement Securities. If (a) any mutilated Security is surrendered to the Trustee, or (b) the Company
and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company and the Trustee such security or indemnity as may be required by them to save each of them harmless,
then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and upon its written request the Trustee shall authenticate and deliver, in exchange for any such
mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount, bearing a certificate number not contemporaneously outstanding. 
  
 In case any such mutilated, destroyed, lost or stolen Security has become or
is about to become due and payable, or is about to be redeemed or purchased by the Company pursuant to Article 3 hereof, the Company in its discretion may, instead of issuing a new Security, pay or purchase such Security, as the case may be.

  
 Upon the issuance of any new Securities under this Section
2.07, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

  
 Every new Security issued pursuant to this Section 2.07 in
lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original contractual obligation of the 
  

 17 

 Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder. 
  
 The provisions of this Section 2.07 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities. 
  
 Section 2.08. Outstanding Securities; Determinations of Holders’ Action. Securities outstanding at any time are all the Securities authenticated by the Trustee except for those cancelled by it, those redeemed, purchased or paid
pursuant to Section 2.07, those delivered to it for cancellation and those described in this Section 2.08 as not outstanding. A Security does not cease to be outstanding because the Company or an Affiliate thereof holds the Security; provided,
however, that in determining whether the Holders of the requisite principal amount of Securities have given or concurred in any request, demand, authorization, direction, notice, consent, waiver, or other Act hereunder, Securities owned by the
Company or any other obligor upon the Securities or any Affiliate of the Company or such other obligor shall be disregarded and deemed not to be outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such
request, demand, authorization, direction, notice, consent, waiver or other act, only Securities which a Responsible Officer of the Trustee actually knows to be so owned shall be so disregarded. Subject to the foregoing, only Securities outstanding
at the time of such determination shall be considered in any such determination (including, without limitation, determinations pursuant to Article 6 and Article 9). 
  
 If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof
satisfactory to it that the replaced Security is held by a bona fide purchaser. 
  
 If the Paying Agent holds, in accordance with this Indenture, on a Redemption Date, or on the Business Day immediately following a Repurchase Date or a Fundamental Change Repurchase Date, or on Stated Maturity, money
or securities, if permitted hereunder, sufficient to pay Securities payable on that date, then from and after such Redemption Date, Repurchase Date, Fundamental Change Repurchase Date or Stated Maturity, as the case may be, such Securities shall
cease to be outstanding and Interest, Contingent Interest and Additional Amounts, if any, on such Securities shall cease to accrue; provided, that if such Securities are to be redeemed, notice of such redemption has been duly given pursuant
to this Indenture or provision therefor satisfactory to the Trustee has been made. 
  
 If a Security is converted in accordance with Article 10, then from and after the time of conversion on the date of conversion, such Security shall cease to be outstanding and Interest, Contingent Interest, Additional
Amounts, if any, and the rights of the Holders therein shall terminate (other than the right to receive the Conversion Settlement Distribution). 
  
 Section 2.09. Temporary Securities. Pending the preparation of Certificated Securities, the Company may execute, and upon Company Order the Trustee
shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the Certificated 
  

 18 

 Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other
variations as the Officers executing such Securities may determine, as conclusively evidenced by their execution of such Securities. 
  
 If temporary Securities are issued, the Company shall cause Certificated Securities to be prepared without unreasonable delay. After the preparation of
Certificated Securities, the temporary Securities shall be exchangeable for Certificated Securities upon surrender of the temporary Securities at the office or agency of the Company designated for such purpose pursuant to Section 2.03, without
charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of Certificated Securities of
authorized denominations. Until so exchanged the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as Certificated Securities. 
  
 Section 2.10. Cancellation. All Securities surrendered for payment, purchase by the Company pursuant to Article 3,
conversion, redemption or registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. The Company may not issue new
Securities to replace Securities it has paid or delivered to the Trustee for cancellation, other than in connection with registrations of transfer or exchange, or that any Holder has converted pursuant to Article 10. No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of by the Trustee in accordance with
the Trustee’s customary procedure. 
  
 Section 2.11.
Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of
such Security for the purpose of receiving payment of the principal amount of the Security or any portion thereof, or the payment of any Redemption Price, Repurchase Price or Fundamental Change Repurchase Price in respect thereof, and Interest,
Contingent Interest or Additional Amounts thereon, for the purpose of conversion and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall
be affected by notice to the contrary. 
  
 Section 2.12. Global
Securities. (a) Notwithstanding any other provisions of this Indenture or the Securities, (A) transfers of a Global Security, in whole or in part, shall be made only in accordance with Section 2.06 and Section 2.12(a)(i) below, (B) transfers of
a beneficial interest in a Global Security for a Certificated Security shall comply with Section 2.06 and Section 2.12(a)(ii) below and Section 2.12(e) below, and (C) transfers of a Certificated Security shall comply with Section 2.06, Section
2.12(a)(iii) and Section 2.12(a)(iv) below. 
  
 (i) Transfer of Global Security. A Global Security may not be transferred, in whole or in part, to any Person other than the Depositary or a nominee or any successor 
  

 19 

 thereof, and no such transfer to any such other Person may be registered; provided that this Section
2.12(a)(i) shall not prohibit any transfer of a Security that is issued in exchange for a Global Security but is not itself a Global Security. No transfer of a Security to any Person shall be effective under this Indenture or the Securities unless
and until such Security has been registered in the name of such Person. Nothing in this Section 2.12(a)(i) shall prohibit or render ineffective any transfer of a beneficial interest in a Global Security effected in accordance with the other
provisions of this Section 2.12. 
  
 (ii)
Restrictions on Transfer of a Beneficial Interest in a Global Security for a Certificated Security. A beneficial interest in a Global Security may not be exchanged for a Certificated Security except upon satisfaction of the requirements set
forth in this paragraph below and in Section 2.12(e) below. Upon receipt by the Trustee of a request to transfer a beneficial interest in a Global Security in accordance with Applicable Procedures for a Certificated Security in the form satisfactory
to the Trustee, together with: 
  
 (A) so long
as the Securities are Restricted Securities, certification in the form set forth in Exhibit C; 
  
 (B) written instructions to the Trustee to make, or direct the Registrar to make, an adjustment on its books and records with respect to
such Global Security to reflect a decrease in the aggregate principal amount of the Securities represented by the Global Security, such instructions to contain information regarding the Depositary account to be decreased; and 
  
 (C) if the Company or the Trustee so requests, an opinion
of counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the Legend, 
  
 then the Trustee shall cause, or direct the Registrar to cause, in accordance with the standing instructions and procedures existing between the Depositary and the
Registrar, the aggregate principal amount of the Securities represented by the Global Security to be decreased by the aggregate principal amount of the Certificated Security to be issued, shall issue such Certificated Security and shall debit or
cause to be debited to the account of the person specified in such instructions a beneficial interest in the Global Security equal to the principal amount of the Certificated Security so issued. 
  
 (iii) Transfer and Exchange of Certificated
Securities. When Certificated Securities are presented to the Registrar with a request: 
  
 (A) to register the transfer of such Certificated Securities; or 
  
 (B) to exchange such Certificated Securities for an equal principal amount of Certificated Securities of
other authorized denominations, 
  

 20 

 the Registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such
transaction are met; provided, however, that the Certificated Securities surrendered for transfer or exchange: 
  
 (1) shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the
Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing; and 
  
 (2) so long as such Securities are Restricted Securities, such Securities are being transferred or exchanged pursuant to an effective
registration statement under the Securities Act or pursuant to clause (x), (y) or (z) below, and are accompanied by the following additional information and documents, as applicable: 
  
 (x) if such Certificated Securities are being delivered to the Registrar by a Holder for registration in
the name of such Holder, without transfer, a certification from such Holder to that effect; or 
  
 (y) if such Certificated Securities are being transferred to the Company, a certification to that effect; or 
  
 (z) if such Certificated Securities are being transferred
pursuant to an exemption from registration, (i) a certification to that effect (in the form set forth in Exhibit C, if applicable) and (ii) if the Company or the Trustee so requests, an opinion of counsel or other evidence reasonably satisfactory to
it as to the compliance with the restrictions set forth in the Legend. 
  
 (iv) Restrictions on Transfer or Exchange of a Certificated Security for a Beneficial Interest in a Global Security. A Certificated Security may not be transferred or exchanged for a beneficial interest in a
Global Security except upon satisfaction of the requirements set forth below. 
  
 Upon receipt by the Trustee of a Certificated Security, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with: 
  
 (A) so long as the Securities are Restricted Securities,
certification, in the form set forth in Exhibit C, that such Certificated Security (A) is being transferred to a QIB in accordance with Rule 144A under the Securities Act or (B) is being transferred pursuant to and in compliance with Rule 144 under
the Securities Act; and 
  
 (B) written
instructions directing the Trustee to make, or to direct the Registrar to make, an adjustment on its books and records with respect to such Global Security to reflect an increase in the aggregate principal amount of the Securities represented by the
Global Security, such instructions to contain information regarding the Depositary account to be credited with such increase, then the Trustee shall cancel such Certificated 
  

 21 

 Security and cause, or direct the Registrar to cause, in accordance with the standing instructions and
procedures existing between the Depositary and the Registrar, the aggregate principal amount of Securities represented by the Global Security to be increased by the aggregate principal amount of the Certificated Security to be exchanged, and shall
credit or cause to be credited to the account of the person specified in such instructions a beneficial interest in the Global Security equal to the principal amount of the Certificated Security so cancelled. If no Global Securities are then
outstanding, the Company shall issue and the Trustee shall authenticate, upon written order of the Company in the form of an Officer’s Certificate, a new Global Security in the appropriate principal amount. 
  
 (b) Subject to the succeeding Section 2.12(c), every Security shall be
subject to the restrictions on transfer provided in the Legend including the delivery of an opinion of counsel, if so provided. Whenever any Restricted Security is presented or surrendered for registration of transfer or for exchange for a Security
registered in a name other than that of the Holder, such Security must be accompanied by a certificate in substantially the form set forth in Exhibit C, dated the date of such surrender and signed by the Holder of such Security, as to compliance
with such restrictions on transfer. The Registrar shall not be required to accept for such registration of transfer or exchange any Security not so accompanied by a properly completed certificate. 
  
 (c) The restrictions imposed by the Legend upon the transferability of any
Security shall cease and terminate when such Security has been sold pursuant to an effective registration statement under the Securities Act or transferred in compliance with Rule 144 under the Securities Act (or any successor provision thereto) or,
if earlier, upon the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision). Any Security as to which such restrictions on transfer shall have expired in accordance with
their terms or shall have terminated may, upon a surrender of such Security for exchange to the Registrar in accordance with the provisions of this Section 2.12 (accompanied, in the event that such restrictions on transfer have terminated by reason
of a transfer in compliance with Rule 144 under the Securities Act or any successor provision, by an opinion of counsel having substantial experience in practice under the Securities Act and otherwise reasonably acceptable to the Company and the
Trustee, addressed to the Company and the Trustee and in form acceptable to the Company and the Trustee, to the effect that the transfer of such Security has been made in compliance with Rule 144 under the Securities Act or such successor
provision), be exchanged for a new Security, of like tenor and aggregate principal amount, which shall not bear the restrictive Legend. The Company shall inform the Trustee of the effective date of any registration statement registering the
Securities under the Securities Act. The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the aforementioned opinion of counsel or registration statement. 
  
 (d) As used in the preceding two paragraphs of this Section 2.12, the term
“transfer” encompasses any sale, pledge, transfer, loan, hypothecation, or other disposition of any Security. 
  

 22 

 (e) The provisions of clauses (i), (ii), (iii), (iv) and (v) below shall apply only to Global Securities:

  
 (i) Notwithstanding any other provisions of
this Indenture or the Securities, a Global Security shall not be exchanged in whole or in part for a Security registered in the name of any Person other than the Depositary or one or more nominees thereof, provided that a Global Security may be
exchanged for Securities registered in the names of any Person designated by the Depositary in the event that (i) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or such
Depositary has ceased to be a “clearing agency” registered under Exchange Act, and a successor Depositary is not appointed by the Company within 90 days (ii) the Company determines at any time that the Securities shall no longer be
represented by Global Securities and shall inform such Depositary of such determination in writing and participants in such Depositary elect to withdraw their beneficial interests in the Global Securities from such Depositary, following notification
by the Depositary of their right to do so or (iii) an Event of Default has occurred and is continuing. Any Global Security exchanged pursuant to clause (i) above shall be so exchanged in whole and not in part, and any Global Security exchanged
pursuant to clauses (ii) or (iii) above may be exchanged in whole or from time to time in part as directed by the Depositary. Any Security issued in exchange for a Global Security or any portion thereof shall be a Global Security; provided that any
such Security so issued that is registered in the name of a person other than the Depositary or a nominee thereof or any successor of either of the foregoing pursuant to this paragraph shall not be a Global Security. 
  
 (ii) Securities issued in exchange for a Global Security or
any portion thereof shall be issued in definitive, fully registered form, shall have an aggregate principal amount equal to that of such Global Security or portion thereof to be so exchanged, shall be registered in such names and be in such
authorized denominations as the Depositary shall designate and shall bear the applicable legends provided for herein. Any Global Security to be exchanged in whole shall be surrendered by the Depositary to the Registrar. With regard to any Global
Security to be exchanged in part, either such Global Security shall be so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with respect to such Global Security, the principal amount thereof shall
be reduced by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Security
issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof. 
  
 (iii) Subject to the provisions of clause (v) below, the registered Holder may grant proxies and otherwise authorize any person, including
Agent Members (as defined below) and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Securities. 
  
 (iv) In the event of the occurrence of any of the events specified in clause (i) above, the Company shall
promptly make available to the Trustee a reasonable supply of Certificated Securities in definitive, fully registered form. 
  
 (v) Neither any members of, or participants in, the Depositary (collectively, the “Agent Members”) nor any
other persons on whose behalf Agent Members may act 
  

 23 

 shall have any rights under this Indenture with respect to any Global Security registered in the name of
the Depositary or any nominee thereof, or under any such Global Security, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder
of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other
authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other person on whose behalf an Agent Member may act, the operation of customary practices of such Persons
governing the exercise of the rights of a Holder of any Security. 
  
 (vi) Except as expressly set forth in this Indenture, including Sections 2.12(a)(ii) and 2.12(e), none of the Trustee, any Paying Agent, Conversion Agent, the Company or the Registrar shall have any responsibility or
obligation to any beneficial owner in the Global Securities, a member of, or a participant in the Depositary or other Person with respect to the accuracy of the records of the Depositary or its nominee or of any participant or member thereof, with
respect to any ownership interest in the Global Securities or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depositary) of any notice (including any notice of redemption) or the payment of
any amount, under or with respect to such Global Securities. All notices and communications to be given to the Holders and all payments to be made to Holders under the Securities shall be given or made only to or upon the order of the registered
Holders (which shall be, in the case of a Global Security, the Depositary or its nominee). The rights of beneficial owners in the Global Securities shall be exercised only through the Depositary subject to the applicable rules and procedures of the
Depositary. Other than as set forth in this Indenture, the Trustee, any Paying Agent, the Conversion Agent, the Company and the Registrar may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to
its members, participants and any beneficial owners. Except as expressly set forth in this Indenture, including Sections 2.12(a)(ii) and 2.12(e), the Trustee, each Paying Agent, the Conversion Agent, the Company and the Registrar shall be entitled
to deal with any depositary (including the Depositary), and any nominee thereof, that is the Holder of any Global Securities as a Holder for all purposes of this Indenture relating to such Global Securities (including the payment of principal,
Interest, Contingent Interest, if any, and Additional Amounts, if any, and the giving of instructions or directions by or to the owner or Holder of a beneficial ownership interest in such Global Securities) as the sole Holder of such Global
Securities and shall have no obligations to the beneficial owners thereof. None of the Trustee, any Paying Agent, the Conversion Agent, the Company or the Registrar shall have any responsibility or liability for any acts or omissions of any such
depositary with respect to such Global Securities, for the records of any such depositary, including records in respect of beneficial ownership interests in respect of any such Global Securities, for any transactions between such depositary and any
participant in such depositary or between or among any such depositary, any such participant and/or any holder or owner of a beneficial interest in such Global Securities or for any transfers of beneficial interests in any such Global Securities.

  

 24 

 (f) The Trustee and the Registrar shall have no obligation or duty to monitor, determine or inquire as to
compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Agent Members or beneficial owners of interests
in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to
determine substantial compliance as to form with the express requirements hereof. 
  
 The Trustee shall have no responsibility for the actions or omissions of the Depositary, or the accuracy of the books and records of the Depositary. 
  
 Section 2.13. CUSIP Numbers. The Company may issue the Securities with one or more “CUSIP”,
“ISIN” or other similar numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP”, “ISIN” or other similar numbers in notices of redemption as a convenience to Holders; provided that any such notice
may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption or purchase and that reliance may be placed only on the other identification numbers
printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee in writing of any change in the CUSIP, ISIN or other similar numbers. 
  
 Section 2.14. Tax Treatment of Securities. The Company agrees, and by
acceptance of a Security, each Holder hereof is deemed to have agreed, with respect to each of the matters set forth below, as follows: 
  
 (a) Tax Treatment: 
  
 (i) to treat the Securities as indebtedness of the Company for all tax purposes; 
  
 (ii) to treat the Securities as indebtedness that are
subject to the special regulations governing contingent payment debt instruments that are contained in U.S. Treasury Regulation section 1.1275-4; and 
  
 (iii) to treat any payment to and receipt by a Holder of Common Stock upon conversion of a Security as a contingent payment under U.S.
Treasury Regulation section 1.1275-4(b) that will result in an adjustment under U.S. Treasury Regulation section 1.1275-4(b)(3)(iv) and U.S. Treasury Regulation section 1.1275-4(b)(6). 
  
 (b) Comparable Yield and Projected Payment Schedule. Solely for purposes of applying U.S. Treasury Regulation section
1.1275-4 to the Securities: 
  
 (i) for United
States federal income tax purposes, to accrue interest with respect to outstanding Securities as original issue discount according to the “noncontingent bond method,” as set forth in U.S. Treasury Regulation section 1.275-4(b); 

 

 25 

 (ii) the comparable yield, as defined in U.S. Treasury Regulation section
1.1275-4(b)(4)(i), for the Securities is 8.50%, compounded semi-annually; 
  
 (iii) the projected payment schedule, as defined in U.S. Treasury Regulation section 1.1275-4(b)(4)(ii) is the schedule found at Annex A of this Indenture; and 
  
 (iv) the Company acknowledges and agrees, and each Holder
and any beneficial owner of a Security, by its purchase of a Security shall be deemed to acknowledge and agree, that (A) the projected payment schedule is determined on the basis of an assumption of the linear growth of the stock price and a
constant dividend yield, (B) the comparable yield and the projected payment schedule are not determined for any other purpose other than for the purposes of applying U.S. Treasury Regulation section 1.1275-4(b) to the Securities and (C) the
comparable yield and the projected payment schedule do not constitute a projection or representation regarding the actual amounts payable on the Securities. 
  
 Section 2.15. Contingent Debt Tax Treatment. Each Security shall bear a legend relating to United States federal income tax matters in the form set
forth below. 
  
 “THIS SECURITY WILL BE ISSUED WITH ORIGINAL
ISSUE DISCOUNT FOR UNITED STATES FEDERAL INCOME TAX PURPOSES. THE ISSUE PRICE FOR THIS SECURITY IS $1,000 PER $1,000 PRINCIPAL AMOUNT AND THE ISSUE DATE FOR THIS SECURITY IS AUGUST 1, 2005. THIS SECURITY IS SUBJECT TO UNITED STATES FEDERAL INCOME
TAX REGULATIONS GOVERNING CONTINGENT PAYMENT DEBT INSTRUMENTS. THE COMPARABLE YIELD FOR THIS SECURITY IS 8.50% PER ANNUM, COMPOUNDED SEMI-ANNUALLY (WHICH WILL BE TREATED AS THE YIELD TO MATURITY FOR UNITED STATES FEDERAL INCOME TAX PURPOSES). FOR
INFORMATION REGARDING THE YIELD TO MATURITY ON THIS SECURITY, AND THE PROJECTED PAYMENT SCHEDULE FOR THIS SECURITY, HOLDERS SHOULD CONTACT THE GENERAL COUNSEL OF BARNES GROUP INC., AT 123 MAIN STREET, BRISTOL CONNECTICUT, 06010-0484.”

  
 Section 2.16. Calculation of Certain Amounts. The
Company shall file with the Trustee promptly at the end of each calendar year (i) a written notice specifying the amount of original issue discount (including daily rates and accrual periods) accrued on outstanding Securities as of the end of such
year and (ii) such other specific information relating to such original issue discount as may then be relevant under the Code. 
  
 ARTICLE 3 
 REDEMPTION
AND REPURCHASES 
  
 Section 3.01.
Company’s Right to Redeem; Notices to Trustee. Prior to February 7, 2011, the Securities shall not be redeemable at the Company’s option. On or after February 7, 2011, the Company, at its option, may redeem the Securities for U.S.
legal tender (“cash”) at any time, in whole or in part, at a redemption price (the “Redemption Price”) equal to 100% of the principal amount of the Securities redeemed, plus any accrued
and unpaid Interest, accrued and 
  

 26 

 unpaid Contingent Interest, if any, and accrued and unpaid Additional Amounts, if any, on the Securities redeemed up to,
but not including, the Redemption Date, provided, that if the Redemption Date is on a date that is after an Interest Record Date and on or prior to the corresponding Interest Payment Date, the Redemption Price shall be 100% of the principal amount
of the Securities redeemed but shall not include accrued and unpaid Interest, accrued and unpaid Contingent Interest, if any, and Additional Amounts, if any. Instead, the Company shall pay such Interest, Contingent Interest, if any, and Additional
Amounts, if any, on the Interest Payment Date to the Holder of record on the corresponding Interest Record Date. If the Company elects to redeem Securities pursuant to this Section 3.01, it shall notify the Trustee in writing of such election
together with the Redemption Date, the Conversion Rate, the principal amount of Securities to be redeemed and the Redemption Price. Notwithstanding the foregoing, the Company may not redeem the Securities if it has failed to pay any Interest,
including Contingent Interest, if any, and Additional Amounts, if any, on the Securities when due and such failure is continuing. 
  
 The Company shall give the notice to the Trustee provided for in this Section 3.01 by a Company Order, at least 45 days but not more than 60 days before
the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee). 
  
 Section 3.02. Selection of Securities to Be Redeemed. If less than all of the Securities are to be redeemed, unless the procedures of the Depositary provide otherwise, the Trustee shall select the Securities to
be redeemed by lot, on a pro rata basis or by another method the Trustee considers fair and appropriate (so long as such method is not prohibited by the rules of any stock exchange or quotation association on which the Securities are then traded or
quoted). The Trustee may select for redemption portions of the principal amount of Securities that have denominations larger than $1,000. 
  
 Securities and portions of Securities that the Trustee selects shall be in principal amounts of $1,000 or an integral multiple of $1,000. Provisions of
this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company promptly (but in any case within 7 days of the Company Order referred to in Section 3.01)
of the Securities or portions of the Securities selected to be redeemed and, in the case of any Securities selected for partial redemption, the method it has chosen for the selection of the Security. 
  
 Following a notice of redemption, Securities and portions of Securities are
convertible, pursuant to Section 10.01(a)(2), by the Holder until the close of business on the Business Day prior to the Redemption Date. If any Security selected for partial redemption is converted in part before termination of the conversion right
with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be from the portion selected for redemption. Securities that have been converted during a selection of Securities
to be redeemed may be treated by the Trustee as outstanding for the purpose of such selection. 
  
 Section 3.03. Notice of Redemption. At least 30 days but not more than 60 days before a Redemption Date, the Company shall mail a notice of redemption (substantially in the form of Exhibit D) by first-class
mail, postage prepaid, to each Holder of Securities to be redeemed. 
  

 27 

 The notice shall identify the Securities to be redeemed and shall state (along with any other information
the Company wishes to include): 
  

	 	(1)	the Redemption Date; 

  

	 	(2)	the Redemption Price; 

  

	 	(3)	the Conversion Rate; 

  

	 	(4)	the name and address of the Paying Agent and Conversion Agent; 

  

	 	(5)	that Securities may be converted at any time before the close of business on the Business Day prior to the Redemption Date; 

  

	 	(6)	that Securities called for redemption and not converted shall be redeemed on the Redemption Date; 

  

	 	(7)	that Holders who want to convert their Securities must satisfy the requirements set forth in the Securities; 

  

	 	(8)	that Securities called for redemption must be surrendered to the Paying Agent (by effecting book-entry transfer of the Securities or delivering Certificated Securities, together
with necessary endorsements, as the case may be) to collect the Redemption Price; 

  

	 	(9)	if fewer than all of the outstanding Securities are to be redeemed, the certificate numbers, if any, and principal amounts of the particular Securities to be redeemed;

  

	 	(10)	that, unless the Company defaults in making payment of such Redemption Price, Interest, Contingent Interest, if any, and Additional Amounts, if any, the Securities called for
redemption shall cease to accrue from and after the Redemption Date; and 

  

	 	(11)	the CUSIP, “ISIN” or other similar number(s), as the case may be, of the Securities being redeemed. 

  
 At the Company’s request, the Trustee shall give the notice of
redemption in the Company’s name and at the Company’s expense, provided that the Company makes such request at least seven Business Days (or such shorter period as may be satisfactory to the Trustee) prior to the date by which such
notice of redemption must be given to Holders in accordance with this Section 3.03. 
  
 Section 3.04. Effect of Notice of Redemption. Once notice of redemption is given, Securities called for redemption become due and payable on the Redemption Date and at the Redemption Price stated in the notice
except for Securities that are converted in accordance with the terms of this Indenture. Upon surrender to the Paying Agent, such Securities shall be paid at the Redemption Price stated in the notice and from and after the Redemption Date (unless

  

 28 

 the Company shall default in the payment of the Redemption Price) such Securities shall cease to bear Interest,
Contingent Interest, if any, and Additional Amounts, if any, and the rights of the Holders therein shall terminate (other than the right to receive the Redemption Price). 
  
 Section 3.05. Deposit of Redemption Price. Prior to 10:00 a.m. (New York City time), on the Redemption Date, the
Company shall deposit with the Paying Agent (or if the Company or a Subsidiary or an Affiliate of either of them is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the Redemption Price of all Securities to be redeemed on
that date other than Securities or portions of Securities called for redemption which on or prior thereto have been delivered by the Company to the Trustee for cancellation or have been converted. The Paying Agent shall as promptly as practicable
return to the Company any money not required for that purpose because of conversion of Securities pursuant to Article 10. If such money is then held by the Company or a Subsidiary or an Affiliate of either in trust and is not required for such
purpose it shall be discharged from such trust. 
  
 Section 3.06.
Securities Redeemed in Part. Upon surrender of a Security that is redeemed in part, the Company shall execute and the Trustee shall, without charge, authenticate and deliver to the Holder a new Security in an authorized denomination equal in
principal amount to the unredeemed portion of the Security surrendered. 
  
 Section 3.07. Repurchase of Securities by the Company at Option of the Holder. (a) On each of February 1, 2011, February 1, 2016 and February 1, 2021 (each, a “Repurchase Date”), each Holder shall have
the option to require the Company to repurchase Securities for which that Holder has properly delivered and not withdrawn a written Repurchase Notice (as described below) at a repurchase price in cash equal to 100% of the principal amount of those
Securities, plus accrued and unpaid Interest, accrued and unpaid Contingent Interest, if any, and accrued and unpaid Additional Amounts, if any, on those Securities, to, but not including, such Repurchase Date (the “Repurchase
Price”); provided, that if the Repurchase Date is on a date that is after an Interest Record Date and on or prior to the corresponding Interest Payment Date, the Repurchase Price shall be 100% of the principal amount of the
Securities repurchased but shall not include accrued and unpaid Interest, accrued and unpaid Contingent Interest, if any, and Additional Amounts, if any. Instead, the Company shall pay such accrued and unpaid Interest, Contingent Interest, if any,
and Additional Amounts, if any, on the Interest Payment Date, to the Holder of Record on the corresponding Interest Record Date. Not later than 20 Business Days prior to any Repurchase Date, the Company shall mail a Company Notice (substantially in
the form of Exhibit E) by first class mail to the Trustee and to each Holder (and to beneficial owners if required by applicable law). The Company Notice shall include a form of Repurchase Notice to be completed by a Holder and shall state:

  
 (i) the Repurchase Price and the Conversion
Rate; 
  
 (ii) the name and address of the Paying
Agent and the Conversion Agent;

 29 

 (iv) that Securities must be surrendered to the Paying Agent (by effecting book-entry
transfer of the Securities or delivering Certificated Securities, together with necessary endorsements, as the case may be) to collect payment; 
  
 (v) that the Repurchase Price for any security as to which a Repurchase Notice has been given and not withdrawn shall be paid promptly
following the later of the Business Day immediately following the Repurchase Date and the time of surrender of such Security as described in clause (iv) above; 
  

(vi) the procedures the Holder must follow to exercise its right to require the Company to repurchase such Holder’s Securities

 (viii) the procedures for withdrawing a Repurchase Notice;

  
 (ix) that, unless the Company defaults in
making payment on Securities for which a Repurchase Notice has been submitted, Interest, Contingent Interest, if any, or Additional Amounts, if any, on such Securities shall cease to accrue from and after the Repurchase Date; and 
  
 (x) the CUSIP, “ISIN” or other similar number(s),
as the case may be, of the Securities. 
  
 At the Company’s
request, the Trustee shall give such Company Notice to each Holder in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Company Notice shall be prepared by the Company.

  
 (b) A Holder may exercise its rights specified in Section
3.07(a) upon delivery to the Paying Agent of a written notice of repurchase (a “Repurchase Notice”) during the period beginning at any time from the opening of business on the date that is 20 Business Days prior to the
relevant Repurchase Date until the close of business on such Repurchase Date, stating: 
  
 (i) if Certificated Securities have been issued, the certificate number(s) of the Securities which the Holder shall deliver to be

 (ii) the portion of the principal amount of the Security which the Holder shall deliver to be repurchased,
which portion must be in principal amounts of $1,000 or an integral multiple of $1,000, and 
  
 (iii) that such Security shall be repurchased by the Company as of the Repurchase Date pursuant to the terms and conditions specified in
Section 6 of the Securities and in this Indenture. 
  

 30 

 The delivery of such Security (together with all necessary endorsements) to the Paying Agent at any time
after delivery of the Repurchase Notice at the offices of the Paying Agent shall be a condition to receipt by the Holder of the Repurchase Price therefor; provided, however, that such Repurchase Price shall be so paid pursuant to this

 The Company shall repurchase from the Holder thereof, pursuant to this
Section 3.07, a portion of a Security, if the principal amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to the repurchase of all of a Security also apply to the repurchase of such portion

 The Paying Agent shall promptly notify the Company of the receipt by it of
any Repurchase Notice or written notice of withdrawal thereof. 
  
 Section 3.08. Repurchase of Securities at Option of the Holder Upon a Fundamental Change. (a) If a Fundamental Change occurs, each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for
cash all of such Holder’s Securities not previously called for redemption by the Company, or any portion thereof that is equal to or an integral multiple of $1,000 principal amount, at a repurchase price equal to 100% of the principal amount of
those Securities, plus accrued and unpaid Interest, accrued and unpaid Contingent Interest, if any, and accrued and unpaid Additional Amounts, if any, on those Securities (the “Fundamental Change Repurchase Price”) to,

 (viii) that the Securities must be surrendered to the Paying Agent (by effecting book-entry transfer of the
Securities or delivering Certificated Securities, together with necessary endorsements, as the case may be) to collect payment; 
  
 (ix) that the Fundamental Change Repurchase Price for any Security as to which a Fundamental Change Repurchase Notice has been duly given

Indenture. 
  
 The delivery of such Security (together with all
necessary endorsements) to the Paying Agent with the Fundamental Change Repurchase Notice at the offices of the Paying Agent shall be a condition to the receipt by the Holder of the Fundamental Change Repurchase Price therefor; provided,
however, that such Fundamental Change Repurchase Price shall be so paid pursuant to this Section 3.08 only if the Security (together with all necessary endorsements) so delivered to the Paying Agent shall conform in all respects to the
description thereof set forth in the related Fundamental Change Repurchase Notice. 
  
 The Company shall repurchase from the Holder thereof, pursuant to this Section 3.08, a portion of a Security if the principal amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of this

of common stock traded or to be traded immediately following such Change of Control on a U.S. national securities exchange or the Nasdaq National Market, and, as a result of such transaction or transactions, the Securities become convertible into
such common stock (and any rights attached thereto). 
  

 33 

 Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the
Fundamental Change Repurchase Notice contemplated by this Section 3.08(c) shall have the right to withdraw such Fundamental Change Repurchase Notice by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.09 at
any time prior to the close of business on the Fundamental Change Repurchase Date. 
  
 The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written withdrawal thereof.

or Fundamental Change Repurchase Notice unless such Repurchase Notice or Fundamental Change Repurchase Notice has first been validly withdrawn as specified in Section 3.09(b). If the Paying Agent holds money sufficient to pay the Fundamental Change
Repurchase Price of the Securities which Holders have elected to require the Company to repurchase on the Business Day following the Fundamental Change Repurchase Date, in accordance with the terms of this Indenture, then, immediately after the
Fundamental Change Repurchase Date, such Securities will cease to be outstanding and Interest and Additional Amounts, if any, on the Securities will cease to accrue, whether or not the Securities are transferred by book-entry or delivered to the
Paying Agent. Thereafter, all other rights of the Holders shall terminate, other than the right to receive the Fundamental Change Repurchase Price upon book-entry transfer of the Securities or delivery of the Securities. 
  
 (b) A Repurchase Notice or Fundamental Change Repurchase Notice may be
withdrawn by means of a written notice of withdrawal delivered to the office of the Paying Agent in accordance with the Repurchase Notice or Fundamental Change Repurchase Notice, as the case may be, at any time (i) in the case of the Repurchase

“successor Person”) and, if any resulting Conversion Obligation relates to Public Acquirer Common Stock that is not issued by such successor Person, such public acquirer, will be a corporation organized and existing under the laws
of the United States of America, any State thereof or the District of Columbia and the successor Person (if not the Company) and the public acquirer, as applicable, will expressly assume, by indenture supplemental hereto, executed and delivered to
the Trustee, in form reasonably satisfactory to the Trustee, all of obligations of the Company or such successor Person and fully and unconditionally assume all of the obligations of the Company under the Securities and this Indenture; 

 
 (b) immediately after giving effect to such transaction,
no Default shall have occurred and be continuing; and 
  
 (c) the Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, merger, conveyance, transfer, sale or lease and, if a supplemental indenture is required in
connection with such transaction, such supplemental indenture, comply with this Article 5 and that all conditions precedent herein provided relating to such transaction have been satisfied. 
  
 For purposes of the foregoing, the transfer (by lease, assignment, sale or
otherwise) of the properties and assets of one or more Subsidiaries (other than to the Company or another Subsidiary), which, if such assets and the assets of each other Subsidiary of the Company were owned by the Company, would constitute all or
substantially all of the properties and assets of the Company, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company. 
  
 The successor Person formed by such consolidation or into which the Company is merged or the successor Person to which such
conveyance, transfer, sale, lease or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor had been 
  

 38 

 named as the Company herein; and thereafter, except in the case of a conveyance, transfer, sale, lease or other
disposition of all or substantially all of the properties and assets of the Company and with respect to obligations the Company may have under a supplemental indenture, the Company shall be discharged from all obligations and covenants under this
Indenture and the Securities. Subject to Section 9.06, the Company, the Trustee and the successor Person shall enter into a supplemental indenture to evidence the succession and substitution of such successor Person and such discharge and release of
the Company; provided, however, that in the case of a conveyance, transfer, sale, lease or other disposition of all or substantially all of the properties and assets of the Company, the Company shall not be released from the
obligations to pay the principal amount of, and Interest, Contingent Interest or Additional Amounts, if any, on the Securities.

 39 

 (g) a failure to pay when due at maturity or a default, event of default or other similar condition or

amount of $15 million or more, unless the acceleration is rescinded, stayed or annulled within 30 days after receipt by the Company of a Notice of Default; 
  
 (h) final unsatisfied judgments (not subject to further appeal) not covered by insurance aggregating in excess of $15,000,000 rendered against the Company
or any of its Subsidiaries are not paid, discharged, stayed or otherwise secured or provided for within 60 days; 
  
 (i) the entry by a court having jurisdiction in the premise of (i) a decree or order for relief in respect of the Company or any of Significant

its property, or (v) the making by the Company or any Significant Subsidiary, of a general assignment for the benefit of creditors, or the admission by the Company or any Significant Subsidiary, in writing of its inability to pay its debts generally
as they become due. 
  
 The foregoing shall constitute Events of
Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative
or governmental body. 
  
 For the avoidance of doubt, clauses (f)
and (g) above shall not constitute an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% in aggregate 
  

 40 

 principal amount of the Securities at the time outstanding notify the Company and the Trustee, of such default and the
Company does not cure such default (and such default is not waived) within the time specified in clauses (f) and (g) above after actual receipt of such notice. Any such notice must specify the default, demand that it be remedied and state that such
notice is a “Notice of Default.” 
  
 Section
6.02. Acceleration. If an Event of Default (other than an Event of Default specified in Section 6.01(i) or Section 6.01(j)) occurs and is continuing (the Event of Default not having been cured or waived), the Trustee by notice to the Company,
or the Holders of at least 25% in aggregate principal amount of the Securities at the time outstanding by notice to the Company and the Trustee, may declare the principal amount of the Securities and any accrued and unpaid Interest, any accrued and
unpaid Contingent Interest, if any, and accrued and unpaid Additional Amounts, if any, on all the Securities to be immediately due and payable. Upon such a declaration, such accelerated amount shall be due and payable immediately. If an Event of
Default specified in Section 6.01(i) or Section 6.01(j) occurs and is continuing, the principal amount of the Securities and any accrued and unpaid Interest, any accrued and unpaid Contingent Interest, if any, and accrued and unpaid Additional
Amounts, if any, on all the Securities shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Securityholders. The Holders of a majority in aggregate principal amount of the Securities
at the time outstanding, by notice to the Trustee (and without notice to any other Securityholder) may rescind an acceleration and its consequences, and thereby waive the Events of Default giving rise to such acceleration, if the rescission would
not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of the principal amount of the Securities and any accrued and unpaid Interest, any accrued and unpaid Contingent Interest, if
any, and accrued and unpaid Additional Amounts, if any, that have become due solely as a result of acceleration. No such rescission shall affect any subsequent Event of Default or impair any right consequent thereto. 
  
 Section 6.03. Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment of the principal amount of the Securities and any accrued and unpaid Interest, any accrued and unpaid Contingent Interest, if any, and accrued and unpaid Additional
Amounts, if any, on the Securities or to enforce the performance of any provision of the Securities or this Indenture. 
  
 The Trustee may maintain a proceeding even if the Trustee does not possess any of the Securities or does not produce any of the Securities in the
proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of, or acquiescence in, the Event of Default. No
remedy is exclusive of any other remedy. All available remedies are cumulative. 
  
 Section 6.04. Waiver of Past Defaults. Subject to Sections 6.07 and 9.02 hereof, the Holders of a majority in aggregate principal amount of the Securities at the time outstanding, by notice to the Trustee (and
without notice to any other Securityholder), may waive any existing or past Default and its consequences except (1) an Event of Default described in clauses (a), (c), (d), and (e) of Section 6.01 or (2) an Event of Default in respect of a provision
that under Section 9.02 cannot be amended without the consent of each Securityholder affected. When a Default is 
  

 41 

 waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent
right. This Section 6.04 shall be in lieu of Section 316(a)1(B) of the TIA and such Section 316(a)1(B) is hereby expressly excluded from this Indenture, as permitted by the TIA. 
  
 Section 6.05. Control by Majority. The Holders of a majority in aggregate principal amount of the Securities at the
time outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture or that the Trustee determines is unduly prejudicial to the rights of other Securityholders or would involve the Trustee in personal liability; provided, that the Trustee may take any other action deemed proper
by the Trustee which is not inconsistent with such direction or this Agreement. Prior to taking any action under this Indenture, the Trustee may require indemnity satisfactory to it in its sole discretion against all losses and expenses caused by
taking or not taking such action. This Section 6.05 shall be in lieu of Section 316(a)1(A) of the TIA and such Section 316(a)1(A) is hereby expressly excluded from this Indenture, as permitted by the TIA. 
  
 Section 6.06. Limitation on Suits. A Securityholder may not pursue any
remedy with respect to this Indenture or the Securities, except in case of a Default described under clause (a) of Section 6.01 or a Default due to the non-payment of the principal amount of the Securities, any accrued and unpaid Interest, any
accrued and unpaid Contingent Interest, if any, or any accrued and unpaid Additional Amounts, if any, unless: 
  

	 	(1)	the Holder gives to the Trustee written notice stating that a Default is continuing; 

  

	 	(2)	the Holders of at least 25% in aggregate principal amount of the Securities at the time outstanding make a written request to the Trustee to pursue the remedy; and

  

	 	(3)	the Trustee does not comply with the request within 60 days after receipt of such notice and offer of security or indemnity; 

  

	 	(4)	the Holders of a majority in aggregate principal amount of the Securities at the time outstanding do not give the Trustee a direction inconsistent with the request during such
60-day period. 

  
 A Securityholder may not use this
Indenture to prejudice the rights of any other Securityholder or to obtain a preference or priority over any other Securityholder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or
forbearances are unduly prejudicial to such Securityholders). 
  
 Section 6.07. Rights of Holders to Receive Payment and Convert. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of the principal amount of the Securities and any accrued and unpaid
Interest, any accrued and unpaid Contingent Interest, if any, and accrued and unpaid Additional Amounts, if any, in respect of the Securities held by such Holder, on or after the respective due dates 
  

 42 

 expressed in the Securities or any Redemption Date, Repurchase Date or Fundamental Change Repurchase Date, and to convert
the Securities in accordance with Article 10, or to bring suit for the enforcement of any such payment or the right to convert on or after such respective dates, shall not be impaired or affected adversely without the consent of such Holder.

  
 Section 6.08. Collection Suit by Trustee. If an Event
of Default described in Section 6.01 clauses (a) through (e) (other than (b)) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount owing with respect
to the Securities and the amounts provided for in Section 7.07. 
  
 Section 6.09. Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the
Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal amount of the Securities and any accrued and unpaid Interest, accrued and
unpaid Contingent Interest, if any, and accrued and unpaid Additional Amounts, if any, in respect of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have
made any demand on the Company for the payment of any such amount) shall be entitled and empowered, by intervention in such proceeding or otherwise: 
  
 (a) to file and prove a claim for the whole principal amount of the Securities and any accrued and unpaid Interest, any accrued and unpaid
Contingent Interest, if any, and accrued and unpaid Additional Amounts, if any, and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel or any other amounts due the Trustee under Section 7.07) and of the Holders allowed in such judicial proceeding, and 
  
 (b) to collect and receive any moneys or other property
payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07. 
  
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
  
 The Company agrees not to object to the Trustee participating as a member of any official committee of creditors of the Company as it deems necessary or
advisable. 
  

 43 

 Section 6.10. Priorities. Any money collected by the Trustee pursuant to this Article 6, and,
after an Event of Default, any money or other property distributable in respect of the Company’s obligations under this Indenture, shall be paid out in the following order: 
  
 FIRST: to the Trustee (including any predecessor Trustee) for amounts due under Section 7.07; 
  
 SECOND: to Securityholders for amounts due and unpaid on the
Securities for the principal amount of the Securities and any accrued and unpaid Interest, any accrued and unpaid Contingent Interest, if any, and accrued and unpaid Additional Amounts, if any, as the case may be, ratably, without preference or
priority of any kind, according to such amounts due and payable on the Securities; and 
  
 THIRD: the balance, if any, to the Company. 
  
 The Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this Section 6.10. At least 15 days before such record
date, the Trustee shall mail to each Securityholder and the Company a notice that states the record date, the payment date and the amount to be paid. 
  
 Section 6.11. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee
for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant (other than the Trustee) in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess
reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply
to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in aggregate principal amount of the Securities at the time outstanding. This Section 6.11 shall be in lieu of Section 315(e) of the TIA and
such Section 315(e) is hereby expressly excluded from this Indenture, as permitted by the TIA. 
  
 Section 6.12. Waiver of Stay, Extension or Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law or any usury or other law wherever enacted, now or at any time hereafter in force, which would prohibit or forgive the Company from paying all or any portion of the principal amount of the
Securities and any accrued and unpaid Interest, any accrued and unpaid Contingent Interest, if any, and accrued and unpaid Additional Amounts, if any, on Securities, as contemplated herein, or which may affect the covenants or the performance of
this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not hinder, delay or impede the execution of any power herein granted to the
Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

 ARTICLE 7 
 TRUSTEE 
  
 Section
7.01. Duties of Trustee. 
  
 (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 such person’s own affairs. 
  
 (b) Except
during the continuance of an Event of Default: 
  

	 	(1)	the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied duties shall be read into this Indenture against the
Trustee; and 

  

	 	(2)	in the absence of bad faith on its part, the Trustee 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 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, the
Trustee shall be under a duty to examine such certificates and opinions to determine whether or not they conform to the requirements of this Indenture, but need not confirm or investigate the accuracy of mathematical calculations or other facts
stated therein. . 

  
 (c) The Trustee may not be
relieved from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that:

extent required by law. The Trustee (acting in any capacity hereunder) shall be under no liability for interest on any money received by it hereunder unless otherwise agreed in writing with the Company (provided that any interest earned on money
held by the Trustee in trust hereunder shall be the property of the Company). 
  
 (g) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of
its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. 
  
 Section 7.02. Rights of Trustee. Subject to the provisions of Section 7.01: 
  
 (a) the Trustee may conclusively rely and shall be protected
in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document (whether in

 (b) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to

liabilities which may be incurred therein or thereby; 
  

 46 

 (g) any request or direction of the Company mentioned herein shall be sufficiently
evidenced by a Company Request or Company Order and any resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution;

facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to, during regular business hours, examine the books, records and premises of the Company, personally or by
agent or attorney at the sole cost of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation; 
  

(i) the Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has
actual knowledge thereof or unless written notice of any event which is in fact such a Default is received by the Trustee at the offices of the Trustee specified in Section 13.02 hereof, and such notice references the Securities and this Indenture;

  
 (j) the rights, privileges, protections,
immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent, custodian for the Depositary
and other Person employed to act hereunder; 
  
 (k) the Trustee may 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

 (l) the permissive rights of the Trustee to take certain
actions under this Indenture shall not be construed as a duty unless so specified herein. 
  
 Section 7.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates with the
same rights it would have if it were not Trustee. Any Paying Agent, Registrar, Conversion Agent or co-registrar may do the same with like rights. However, the Trustee must comply with Section 7.10 and Section 7.11.

representation as to, and shall have no responsibility for, the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use or application by the Company of the Securities or of the proceeds from
the Securities, it shall not be responsible for the correctness of any statement in the registration statement for the Securities under the Securities Act or in any offering document for the Securities, the Indenture or the Securities (other than
its certificate of authentication), or the determination as to which beneficial owners are entitled to receive any notices hereunder. 
  

 47 

 Section 7.05. Notice of Defaults. If a Default or Event of Default occurs and if it is known to
the Trustee, the Trustee shall give to each Securityholder notice of the Default or Event of Default within 90 days after it occurs, or, if later, within 15 days after it is known to the Trustee, unless such Default or Event of Default shall have
been cured or waived before the giving of such notice. Notwithstanding the preceding sentence, except in the case of a Default or Event of Default described in clauses (d) and (e) of Section 6.01, the Trustee may withhold the notice if and so long
as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interest of the Securityholders. The Trustee shall not be deemed to have knowledge of a Default or Event of Default unless a Responsible
Officer of the Trustee has received written notice of such Default or Event of Default, which notice specifically references this Indenture and the Securities. 
  

Section 7.06. Reports by Trustee to Holders. Within 60 days after each May 15 beginning with May 15, 2006, the Trustee shall mail to each
Securityholder a brief report dated as of such May 15 that complies with TIA Section 313(a), if required by such Section 313(a). The Trustee also shall comply with TIA Section 313(b). Any reports required by this Section 7.06 shall be transmitted by
mail to Securityholders pursuant to TIA Section 313(c). A copy of each report at the time of its mailing to Securityholders shall be filed with the SEC and each securities exchange, if any, on which the Securities are listed. The Company agrees to
notify the Trustee promptly in writing whenever the Securities become listed on any securities exchange and of any delisting thereof. 
  
 Section 7.07. Compensation and Indemnity. The Company agrees: 
  
 (a) to pay to the Trustee from time to time such compensation as the Company and the Trustee shall from time to time agree in writing for
all services rendered by it hereunder (which compensation shall not be limited (to the extent permitted by law) by any provision of law in regard to the compensation of a trustee of an express trust); 
  
 (b) to reimburse the Trustee upon its request for all
reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the reasonable expenses, advances and disbursements of its agents and
counsel), except any such expense, disbursement or advance as may be attributable to its own negligence, willful misconduct or bad faith; and 
  
 (c) to indemnify the Trustee or any predecessor Trustee and their agents for, and to hold them harmless against, any loss, damage, claim,
liability, cost or expense (including reasonable attorney’s fees and expenses, and taxes (other than taxes based upon, measured by or determined by the income of the Trustee)) incurred without negligence, willful misconduct or bad faith on its
part, arising out of or in connection with the acceptance or administration of this trust, including the reasonable costs and expenses of defending itself against any claim (whether asserted by the Company or any Holder or any other person) or
liability in connection with the exercise or performance of any of its powers or duties hereunder. 
  

 48 

 To secure the Company’s payment obligations in this Section 7.07, the Trustee shall have a lien
prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay the principal amount of, or the Redemption Price, Repurchase Price, Fundamental Change Repurchase Price, Interest, Contingent
Interest or Additional Amounts, if any, as the case may be, on particular Securities. 
  
 The Company’s payment, reimbursement and indemnity obligations pursuant to this Section 7.07 shall survive the satisfaction and discharge of this Indenture, the resignation or removal of the Trustee and the
termination of this Indenture for any reason. In addition to and without prejudice to its rights hereunder, when the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 6.01(i) or Section 6.01(j),
the expenses, including the reasonable charges and expenses of its counsel and the compensation for services payable pursuant to Section 7.07(a), are intended to constitute expenses of administration under any applicable federal or state bankruptcy,
insolvency or similar laws. 
  
 For the purposes of this Section
7.07, the “Trustee” shall include any predecessor Trustee; provided, however, that except as may be otherwise agreed among the parties, the negligence, willful misconduct or bad faith of any Trustee hereunder shall not affect the rights of
any other Trustee hereunder. 
  
 Section 7.08. Replacement of
Trustee. The Trustee may resign at any time by so notifying the Company; provided, however, no such resignation shall be effective until a successor Trustee has accepted its appointment pursuant to this Section 7.08. The Holders of a majority in
aggregate principal amount of the Securities at the time outstanding may remove the Trustee by so notifying the Trustee and the Company in writing. The Company shall remove the Trustee if: 
  

	 	(1)	the Trustee fails to comply with Section 7.10; 

  

	 	(2)	the Trustee is adjudged bankrupt or insolvent; 

  

	 	(3)	a receiver or public officer takes charge of the Trustee or its property; or 

  

	 	(4)	the Trustee otherwise becomes incapable of acting. 

  
 If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint, by resolution of
its Board of Directors, a successor Trustee. 
  
 A successor
Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company satisfactory in form and substance to the retiring Trustee and the Company. Thereupon the resignation or removal of the retiring Trustee shall
become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Securityholders. The retiring Trustee shall promptly
transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07. 
  

 49 

 If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is
removed, the retiring Trustee, the Company or the Holders of a majority in aggregate principal amount of the Securities at the time outstanding may petition any court of competent jurisdiction at the expense of the Company for the appointment of a
successor Trustee. 
  
 If the Trustee fails to comply with Section
7.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
  
 So long as no Default or Event of Default shall have occurred and be continuing, if the Company shall have delivered to the Trustee (i) a Board Resolution
appointing a successor Trustee, effective as of a date at least 30 days after delivery of such Resolution to the Trustee, and (ii) an instrument of acceptance of such appointment, effective as of such date, by such successor Trustee in accordance
with this Indenture, the Trustee shall be deemed to have resigned as contemplated in this Section 7.08, the successor Trustee shall be deemed to have been accepted as contemplated in this Indenture, all as of such date, and all other provisions of
this Indenture shall be applicable to such resignation, appointment and acceptance. 
  
 Section 7.09. Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another Person, the
resulting, surviving or transferee Person without any further act shall be the successor Trustee, subject to Sections 7.10 and 7.11. 
  
 Section 7.10. Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of TIA Sections 310(a)(1) and 310(b). The
Trustee (or any parent holding company) shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. Nothing herein contained shall prevent the Trustee from filing with the
Commission the application referred to in the penultimate paragraph of TIA Section 310(b). 
  
 Section 7.11. Preferential Collection of Claims Against Company. The Trustee shall comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or
been removed shall be subject to TIA Section 311(a) to the extent indicated therein. 
  
 ARTICLE 8 
 DISCHARGE OF INDENTURE 
  
 Section 8.01. Discharge of Liability on Securities. When (i) the
Company causes to be delivered to the Trustee all outstanding Securities (other than Securities replaced or repaid pursuant to Section 2.07) for cancellation or (ii) all outstanding Securities have become due and payable and the Company deposits
with the Trustee cash sufficient to pay all amounts due and owing on all outstanding Securities (other than Securities replaced pursuant to Section 2.07), and if in either case the Company pays all other sums payable hereunder by the Company, then
this 
  

 50 

 Indenture shall, subject to Section 7.07, cease to be of further effect. The Trustee shall join in the execution of a
document prepared by the Company acknowledging satisfaction and discharge of this Indenture on demand of the Company accompanied by an Officer’s Certificate and Opinion of Counsel and at the cost and expense of the Company. 
  
 Section 8.02. Repayment to the Company. The Trustee and the Paying
Agent shall return to the Company upon written request any money or securities held by them for the payment of any amount with respect to the Securities that remains unclaimed for two years, subject to applicable abandoned property law. After return
to the Company, Holders entitled to the money or securities must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person and the Trustee and the Paying Agent shall have no further
liability to the Securityholders with respect to such money or securities for that period commencing after the return thereof. 
  
 Section 8.03. Application of Trust Money. The Trustee shall hold in trust all money and other consideration deposited with it pursuant to Section
8.01 and shall apply such deposited money and other consideration through the Paying Agent and in accordance with this Indenture to the payment of amounts due on the Securities. Money and other consideration so held in trust is subject to the
Trustee’s rights under Section 7.07. 
  
 ARTICLE 9

 (n) make any changes or modifications necessary in
connection with the registration of the Securities under the Securities Act as contemplated in the Registration Rights Agreement; provided, however, that any such change or modification does not, in the good faith opinion of the Board
of Directors of the Company (as evidenced by a Board Resolution) and the Trustee, adversely affect the interests of the Holders of Securities in any material respect; or 
  
 (o) add or modify any other provisions herein with respect to matters or questions arising hereunder which
the Company and the Trustee may deem necessary or desirable and which, in the good faith opinion of the Board of Directors of the Company (as evidenced by a Board Resolution) and the Trustee, which change individually or in the aggregate with all
other such changes, shall not adversely affect the interests of the Holders of Securities in any material respect. 
  
 Section 9.02. With Consent of Holders. Except as provided below in this Section 9.02 and in Section 9.01, this Indenture or the Securities may be
amended, modified or supplemented, and noncompliance in any particular instance with any provision of this Indenture or the Securities may be waived, in each case with the written consent of the Holders of at least a majority of the principal amount
of the Securities at the time outstanding. 
  

 52 

 Without the written consent or the affirmative vote of each Holder of Securities affected thereby, an
amendment, supplement or waiver under this Section 9.02 may not: 
  
 (a) reduce the principal amount of or change the Stated Maturity of any Security, or the payment date of any installment of Interest, Contingent Interest or Additional Amounts payable on any Security;

 (e) change the currency of payment of such Securities or Interest, Contingent Interest, Additional Amounts,
Redemption Price, Fundamental Change Repurchase Price or Repurchase Price thereon;

hereof; 
  
 (g) modify the redemption provisions

 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, but it shall be
sufficient if such consent approves the substance thereof. 
  
 After an amendment under this Section 9.02 becomes effective, the Company shall mail to each Holder a notice briefly describing the amendment. 
  

 53 

 Section 9.03. Compliance With Trust Indenture Act. Every supplemental indenture executed pursuant
to this Article shall comply with the TIA as then in effect. 
  
 Section 9.04. Revocation and Effect of Consents, Waivers and Actions. Until an amendment, waiver or other action by Holders becomes effective, a consent thereto by a Holder of a Security hereunder is a continuing consent by the
Holder and every subsequent Holder of that Security or portion of the Security that evidences the same obligation as the consenting Holder’s Security, even if notation of the consent, waiver or action is not made on the Security. However, any
such Holder or subsequent Holder may revoke the consent, waiver or action as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date the amendment, waiver or action becomes
effective. After an amendment, waiver or action becomes effective, it shall bind every Securityholder. 
  
 Section 9.05. Notice of Amendments, Notation on or Exchange of Securities. Securities authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article 9 may, and shall if required by the Company, bear a notation in form approved by the Company as to any matter provided for in such supplemental indenture. If the Company shall so determine, new
Securities so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for outstanding
Securities. 
  
 Section 9.06. Trustee to Sign Supplemental
Indentures. The Trustee shall sign any supplemental indenture authorized pursuant to this Article 9 if the amendment contained therein does not affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but
need not, sign such supplemental indenture. In signing such supplemental indenture the Trustee shall receive, and (subject to the provisions of Section 7.01) shall be fully protected in conclusively relying upon, an Officer’s Certificate and an
Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture. 
  
 Section 9.07. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture
shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby. 
  
 ARTICLE 10 
 CONVERSIONS 
  
 Section 10.01.
Conversion Privilege. (a) Subject to and upon compliance with the provisions of this Article 10, a Holder of a Security shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is
$1,000 principal amount or an integral multiple thereof) of such Security prior to the close of business on the Business Day immediately preceding Stated Maturity into cash and shares of Common Stock, if any, at the Conversion Rate (the
“Conversion Obligation”) in effect on the date of conversion only as follows: 
  

 54 

 (1) during any fiscal quarter of the Company (a “Fiscal
Quarter”) commencing after September 30, 2005 (and only during such Fiscal Quarter), if the Closing Price of the Common Stock for at least 20 Trading Days during the period of 30 consecutive Trading Days ending on the last Trading
Day of the immediately preceding Fiscal Quarter is greater than or equal to 130% of the Conversion Price in effect on such last Trading Day; 
  
 (2) prior to August 1, 2024, during the five Business Days immediately following any five consecutive Trading Day period in which the
Trading Price per $1,000 original principal amount of the Securities (as determined following a request by a Securityholder in accordance with the procedures described below) for each day of that period was less than 98% of the product of the
Closing Price of the Company’s Common Stock and the current Conversion Rate of the Securities on each such day; 
  
 (3) at any time prior to the close of business on the Business Day immediately preceding the Redemption Date, if the Company has called
the Securities for redemption pursuant to Article 3 hereof, even if the Securities are not otherwise convertible at that time; 
  
 (4) as provided in clause (b) of this Section 10.01. 
  
 The Company or, at its option, the Conversion Agent on behalf of the Company, shall determine on a daily basis during the
time periods specified in Section 10.01(a)(1) or, following a request by a Securityholder in accordance with the procedures described below, Section 10.01(a)(2), whether the Securities shall be convertible as a result of the occurrence of an event
specified in such Sections and, if the Securities shall be so convertible, the Company or the Conversion Agent, as applicable, shall promptly deliver to the Trustee and Conversion Agent or the Company, as applicable, written notice thereof. Whenever
the Securities shall become convertible pursuant to this Section 10.01 (as determined in accordance with this Section 10.01), the Company or, at the Company’s request, the Trustee in the name and at the expense of the Company, shall promptly
notify the Holders of the event triggering such convertibility in the manner provided in Section 12.02, and the Company shall also promptly disseminate a press release through Dow Jones & Company, Inc. or Bloomberg Business News and publish such
information on the Company’s Website or through another public medium the Company may use at that time. Any notice so given shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. 
  
 The Trustee shall have no obligation to determine the Trading Price of the
Securities unless the Company has requested such determination; and the Company shall have no obligation to make such request unless a Securityholder delivers written notice to the Company at the address or telecopier number set forth in Section
13.02 stating that such Securityholder is requesting that the Trustee make such determination set forth in Section 10.01(a)(2), with such notice being accompanied with reasonable evidence that (x) the Person is a Securityholder as of the date the
notice is delivered and (y) the Trading Price per $1,000 original principal amount of Securities would be less than 98% of the product of the Closing Price of the Company’s Common Stock and the current Conversion Rate of the Securities. At such
time, the Company 
  

 55 

 will be required to instruct the Trustee to determine the Trading Price of the Securities beginning on the next Trading
Day and on each successive Trading Day until the Trading Price per $1,000 original principal amount of Securities is greater than or equal to 98% of the product of the Closing Price of the Company’s Common Stock and the current Conversion Rate
of the Securities. 
  
 The Trustee shall be entitled at its sole
discretion to consult with the Company and to request the assistance of the Company in connection with the Trustee’s duties and obligations pursuant to Section 10.01(a) hereof, and the Company agrees, if requested by the Trustee, to cooperate
with, and provide assistance to, the Trustee in carrying out its duties under this Section 10.01; provided, however, that nothing herein shall be construed to relieve the Trustee of its duties pursuant to Section 10.01(a) hereof.

  
 (b) In the event that: 
  
 (1) (A) the Company distributes to all holders of Common
Stock rights or warrants entitling them to purchase, for a period expiring within 60 days after the date of such distribution, Common Stock at less than the Closing Price of the Common Stock on the Trading Day immediately preceding the announcement
date for such distribution; or (B) the Company distributes to all holders of Common Stock assets (including cash), debt securities or rights, warrants or options to purchase the Company’s securities, which distribution has a per share value as
determined by the Board of Directors exceeding 10% of the Closing Price of the Common Stock on the Trading Day immediately preceding the announcement date of such distribution, then, in either case, the Securities may be surrendered for conversion
at any time on and after the date that the Company gives notice to the Holders of such distribution, which shall be not less than 20 Business Days prior to the Ex-Dividend Date for such distribution (provided, however, that such notice shall not be
given in respect of the issuance or distribution of rights under the Company’s Rights Agreement or any extension, renewal, amendment, supplement or replacement thereof), until the earlier of the close of business on the Business Day immediately
preceding the Ex-Dividend Date or the date the Company announces that such distribution shall not take place, even if the Securities are not otherwise convertible at such time; provided that no Holder of a Security shall have the right to
convert if the Holder may otherwise participate in such distribution without conversion in respect of Securities held by such Holder; or 
  
 (2) a Change of Control occurs pursuant to clause (1) of the definition thereof or clause (3) of the definition thereof pursuant to which
the Common Stock is to be converted into cash, securities or other property, then the Securities may be surrendered for conversion at any time from and after the date which is 15 days prior to the anticipated effective date of such transaction until
and including the date which is 15 days after the actual effective date of such transaction (or, if such transaction also constitutes a Change of Control pursuant to which Holders have a right to require the Company to repurchase the Securities
pursuant to Section 3.08, until the applicable Fundamental Change Repurchase Date). The 
  

 56 

 Company shall notify Holders at the time the Company publicly announces the Change of Control transaction
giving rise to the above conversion right (but in no event less than 15 days prior to the anticipated effective date of such transaction). If the Company engages in any reclassification of the Common Stock (other than a subdivision or combination of
its outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value) or is party to a consolidation, merger, binding share exchange or transfer of all or substantially all of its assets
pursuant to which Holders of Common Stock would be entitled to receive cash, securities or other property, then at the effective time of such transaction, to the extent that it constitutes a Change of Control as described in this paragraph above as
giving rise to a conversion right, the Conversion Obligation and the Conversion Settlement Distribution shall be based on the applicable Conversion Rate and the kind and amount of cash, securities or other property that a holder of one share of the
Common Stock would have received in such transaction (such property, collectively, the “Exchange Property”). In addition, if a Holder converts Securities following the effective time of any such transaction, any
amounts of the Conversion Settlement Distribution to be settled in shares of Common Stock shall be paid in such Exchange Property rather than shares of Common Stock. If the transaction also constitutes a Change of Control, (A) a Holder can require
the Company to repurchase all or a portion of its Securities pursuant to Section 3.08 or, (B) if such Holder elects, instead, to convert all or a portion of its Securities, such Holder shall receive Additional Shares upon conversion pursuant to
Section 10.01(c), in each case, subject to the terms and conditions set forth in each such Section. 
  
 (c) If and only to the extent a Holder timely elects to convert Securities during the period specified in Section 10.01(b)(2) above on or prior to
February 7, 2011, and 10% or more of the consideration for the Common Stock in such Change of Control transaction consists of consideration other than common stock traded or scheduled to be traded immediately following such transaction on a U.S.
national securities exchange or the Nasdaq National Market, the Conversion Rate shall be increased by an additional number of shares of Common Stock (the “Additional Shares”) as described below; provided that if
the Stock Price paid in connection with such transaction is greater than $125.00 or less than $34.30 (subject in each case to adjustment as described below), no Additional Shares shall be added to the Conversion Rate. Notwithstanding this Section
10.01(c), if the Company elects to adjust the Conversion Rate pursuant to Section 10.01(d), the provisions of Section 10.01(d) shall apply in lieu of the provisions of this Section 10.01(c). The Company shall notify Holders, at least 20 days prior
to the anticipated effective date of such transaction causing any increase of the Conversion Rate pursuant to this Section 10.01(c), whether the Company elects to increase the Conversion Rate as described above or to adjust the Conversion Rate
pursuant to Section 10.01(d). 
  
 The number of Additional Shares
to be added to the Conversion Rate as described in the immediately preceding paragraph shall be determined by reference to the table attached as Schedule I hereto, based on the effective date of such Change of Control transaction and the Stock Price
paid in connection with such transaction; provided that if the Stock Price is between two Stock Price amounts in the table or such effective date is between two effective dates in the table, the number of Additional Shares shall be determined
by a straight-line interpolation 
  

 57 

 between the number of Additional Shares set forth for the higher and lower Stock Price amounts and the two dates, as
applicable, based on a 365/366-day year. The “effective date” with respect to a Change of Control transaction means the date that a Change of Control becomes effective. 
  
 With respect to any Securities tendered for conversion to which Additional
Shares apply, any shares of Common Stock to be delivered upon conversion of such Securities pursuant to Section 10.02 shall be delivered to Holders who elect to convert their Securities on the later of (i) the fifth Business Day following the
effective date and (2) the third Business Day following the final day of the Conversion Reference Period. 
  
 The Stock Prices set forth in the first row of the table in Schedule I hereto shall be adjusted as of any date on which the Conversion Rate of the
Securities is adjusted pursuant to Section 10.04. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to
the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares shall be adjusted in the same manner as the Conversion Rate as set forth in Section 10.04.
Notwithstanding anything to the contrary herein, the maximum amount of Additional Shares is 5.4516 per $1,000 principal amount of Securities, subject to adjustments in the same manner as the conversion rate as set forth in Section 10.04. 

 
 Notwithstanding the foregoing, in no event shall the total number of
shares of Common Stock issuable upon conversion of the Securities exceed 29.1545 per $1,000 principal amount of Securities, subject to adjustments in the same manner as the Conversion Rate as set forth in Section 10.04. 
  
 (d) Notwithstanding the provisions of Section 10.01(c), in the case of a
Change of Control that would lead to the issuance of Additional Shares as set forth in clause (c) above that is also a Public Acquirer Change of Control, the Company may, in lieu of increasing the Conversion Rate by Additional Shares as described in
Section 10.01(c), elect to adjust the Conversion Rate and the related Conversion Obligation such that from and after the effective date of such Public Acquirer Change of Control, Holders of Securities shall be entitled to convert their Securities
(subject to the satisfaction of the conditions to conversion set forth in Section 10.01(a)) into Public Acquirer Common Stock. The Conversion Rate following the effective date of such transaction will be a number of shares of Public Acquirer Common
Stock equal to the product of the Conversion Rate in effect immediately before the Public Acquirer Change of Control times the average of the quotients obtained, for each Trading Day in the 20 consecutive Trading Day period ending on the Trading Day
immediately preceding the effective date of such Public Acquirer Change of Control (the “Valuation Period”), of: 
  
 (i) the Acquisition Value of the Company’s Common Stock on each such Trading Day in the Valuation Period, divided by 
  
 (ii) the Closing Price of the Public Acquirer Common Stock on each such
Trading Day in the Valuation Period. 
  

 58 

 The “Acquisition Value” of the Common Stock means, for each Trading Day in
the Valuation Period, the value of the consideration paid per share of Common Stock in connection with such Public Acquirer Change of Control, as follows: 
  
 (i) for any cash, 100% of the face amount of such cash; 
  
 (ii) for any Public Acquirer Common Stock, 100% of the Closing Price of such Public Acquirer Common Stock on such Trading Day; and 
  
 (iii) for any other securities, assets or property, 102% of the fair market
value of such security, asset or property on such Trading Day, as determined by two independent nationally recognized investment banks selected by the Company for this purpose. 
  
 “Public Acquirer Change of Control” means a Change of Control pursuant to clause (1) or (3)
of the definition thereof set forth above and the acquirer, the Person formed by or surviving the merger or consolidation or any entity that is direct or indirect “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act) of more
than 50% of such Person’s or Acquirer’s Voting Stock has a class of common stock traded on a U.S. national securities exchange or quoted on the Nasdaq National Market or which shall be so traded or quoted when issued or exchanged in
connection with such Change of Control (the “Public Acquirer Common Stock”); provided, that if there is more than one of such entity, the relevant entity shall be such entity with the most direct beneficial
ownership to such acquirer’s or Person’s capital stock. 
  
 Upon a Public Acquirer Change of Control, if the Company so elects, Holders may convert their Securities (subject to the satisfaction of the conditions to conversion set forth in Section 10.01(a)) at the adjusted Conversion Rate described
above but shall not be entitled to the increased Conversion Rate described in Section 10.01(c). The Company shall notify Holders of its election in its notice to Holders pursuant to Section 10.01(b)(2) above. Holders may convert their Securities
upon a Public Acquirer Change of Control during the period specified in Section 10.01(b)(2). In addition, Holders can also, subject to certain conditions, require the Company to repurchase all or a portion of their Securities as described in Section
3.08. 
  
 After any adjustment of the Conversion Rate in
connection with a Public Acquirer Change of Control, the Conversion Rate shall be subject to further similar adjustments in the event that any of the events described in Section 10.04 occur thereafter. 
  
 Section 10.02. Conversion Procedure; Conversion Rate; Fractional
Shares. (a) Subject to Section 10.01 and the Company’s rights under Section 10.03, each Security shall be convertible at the office of the Conversion Agent into a combination of cash and fully paid and nonassessable shares (calculated to
the nearest 1/100th of a share) of Common Stock, if any at a rate (the “Conversion Rate”) equal to, initially, 23.7029 shares of Common Stock for each $1,000 principal amount of Securities. The Conversion Rate shall be
adjusted in certain instances as provided in Section 10.04 hereof, but shall not be adjusted for any accrued and unpaid Interest, Contingent Interest, or Additional Amounts, if any. Upon conversion, no payment shall be made by the Company with
respect to any accrued and unpaid Interest, 
  

 59 

 including Contingent Interest, if any; provided that if a Conversion Date with respect to any Security occurs
between an Interest Record Date for the payment of Interest (including Contingent Interest, if any) but prior to the corresponding Interest Payment Date, Interest, Contingent Interest, if any, and Additional Amounts, if any, will be paid to the
Holder of record of such Security on such Interest Record Date. Instead, such amount shall be deemed paid by the applicable Conversion Settlement Distribution delivered upon conversion of any Security. In addition, no payment or adjustment shall be
made in respect of dividends on the Common Stock with a record date prior to the Conversion Date. Notwithstanding the foregoing, upon conversion, a Holder shall receive any accrued and unpaid Additional Amounts to the Conversion Date. The Company
shall not issue any fraction of a share of Common Stock in connection with any conversion of Securities, but instead shall, subject to Section 10.03 hereof, make a cash payment (calculated to the nearest cent) equal to such fraction multiplied by
the Closing Price of the Common Stock on the Trading Day prior to the Conversion Date. 
  
 (b) Before any Holder of a Security shall be entitled to convert the same into a combination of cash and Common Stock, if any, such Holder shall (1) in the case of Global Securities, comply with the procedures of the
Depositary in effect at that time for converting a beneficial interest in a Global Security, and in the case of Certificated Securities, surrender such Securities, duly endorsed to the Company or in blank, at the office of the Conversion Agent, and
(2) give written notice to the Company in the form on the reverse of such Certificated Security (the “Conversion Notice”) at said office or place that such Holder elects to convert the same and shall state in writing
therein the principal amount of Securities to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for Common Stock included in the Conversion Settlement Distribution, if any, to be
registered. 
  
 Before any such conversion, a Holder also shall
pay all taxes or duties, if any, as provided in Section 10.06 and any amount payable pursuant to Section 10.02(g). 
  
 If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares of Common Stock, if any, that
shall be deliverable upon conversion as part of the Conversion Settlement Distribution shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted thereby) so surrendered.

  
 (c) A Security shall be deemed to have been converted as of
the close of business on the date (the “Conversion Date”) that the Holder has complied with Section 10.02(b). 
  
 (d) The Company shall, on the Conversion Settlement Date, (i) pay the cash component (including cash in lieu of any fraction of a share to which such
Holder would otherwise be entitled) of the Conversion Obligation determined pursuant to Section 10.03 to the Holder of a Security surrendered for conversion, or such Holder’s nominee or nominees, and (ii) issue, or cause to be issued, and
deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates for the number of full shares of Common Stock, if any, to which such Holder shall be entitled as part of such Conversion Obligation. The
Company shall not be required to deliver certificates for shares of Common Stock while the stock transfer books for such stock or the security register are duly closed for any purpose, but certificates for shares of Common Stock shall be issued and
delivered as soon as practicable after the opening of 
  

 60 

 such books or security register, and the Person or Persons entitled to receive the Common Stock as part of the applicable
Conversion Settlement Distribution upon such conversion shall be treated for all purposes as the record holder or holders of such Common Stock, as of the close of business on the applicable Conversion Settlement Date. 
  
 (e) In case any Security shall be surrendered for partial conversion, the
Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Security so surrendered, without charge to such Holder (subject to the provisions of Section 10.06 hereof), a new Security or
Securities in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Securities. 
  
 (f) By delivering the combination of cash and shares of Common Stock, if any, together with a cash payment in lieu of any fractional shares to the
Conversion Agent or to the Holder or such Holder’s nominee or nominees, the Company shall have satisfied in full its Conversion Obligation with respect to such Security, and upon such delivery, accrued and unpaid Interest, if any, and
Contingent Interest, if any, with respect to such Security shall be deemed to be paid in full rather than canceled, extinguished or forfeited, and such amounts shall no longer accrue. 
  
 (g) If a Securityholder delivers a Conversion Notice after the Interest Record Date for a payment of Interest (including
Contingent Interest, if any) but prior to the corresponding Interest Payment Date, such Securityholder must pay to the Company, at the time such Securityholder surrenders Securities for conversion, an amount equal to the Interest (including
Contingent Interest, if any, and excluding, for the avoidance of doubt, Additional Amounts, if any), that has accrued and shall be paid on the related Interest Payment Date. The preceding sentence shall not apply if (1) the Company has specified a
Redemption Date that is after an Interest Record Date but on or prior to the corresponding Interest Payment Date, (2) the Company has specified a Fundamental Change Repurchase Date during such period referred to in clause (1) of this paragraph or
(3) to the extent of any overdue Interest if any overdue Interest exists at the time of conversion with respect to the Securities converted. 
  
 Section 10.03. Payment Upon Conversion. (a) Upon conversion of Securities, the Company shall deliver to Holders surrendering Securities for
conversion, for each $1,000 principal amount of Securities, a settlement amount (the “Conversion Settlement Distribution”) on the Conversion Settlement Date consisting of: 
  
 (i) cash amount (the “Cash
Amount”) equal to the lesser of $1,000 and the Conversion Value; and 
  
 (ii) to the extent the Conversion Value exceeds $1,000, a number of shares of Common Stock (the “Residual Value
Shares”) equal to the sum of the Daily Share Amounts for each Trading Day of the Conversion Reference Period, subject to the Company’s right to deliver cash in lieu of all or a portion of such Residual Value Shares as described
below. 
  
 The “Daily Share Amount” means for each
Trading Day of the Conversion Reference Period described below, the number of shares equal to the greater of: 
  
 (A) zero and 
  

 61 

 (B) the quotient of 
  
 (1) 5% of the difference between (x) the product of the Conversion Rate (plus any Additional Shares as
described under Section 10.01(c)) and the Closing Price of the Common Stock on such date, and (y) $1,000, divided by 
  
 (2) the Closing Price of the Common Stock for such day. 
  
 Notwithstanding the foregoing, the Company may elect to pay cash to the Holders of the Securities surrendered for conversion
in lieu of all or a portion of the Residual Value Shares issuable upon conversion of such Securities. If the Company elects to pay cash for all or a portion of the Residual Value Shares in lieu of delivery of the Common Stock, it shall inform the
Holders who have surrendered their Securities for conversion through the Trustee of the dollar amount to be satisfied in cash (expressed as a percentage of each Residual Value Share that will be paid in cash in lieu of shares of the Common Stock) at
any time on or before the date that is three (3) Business Days following the Conversion Date (“Cash Settlement Notice Period”), unless the Company has already informed the Holders of its election in connection with an
optional redemption of the Securities under Section 3.01. If the Company timely elects to pay cash for any portion of the shares of Common Stock otherwise issuable to the Holders of the Securities, each Holder may retract its respective Conversion
Notice at any time during the two Business Day period immediately following the Cash Settlement Notice Period (the “Conversion Retraction Period”). If the Company does not make such an election, no such retraction can
be made (and a Conversion Notice shall be irrevocable). The amount of cash payable to the Holders in respect of each Residual Value Share otherwise issuable upon conversion shall equal the sum of the Residual Cash Value (as defined below) for such
share of Common Stock calculated for each day of the Conversion Reference Period. The “Residual Cash Value” for each date shall be the product of (1) the percentage of each Residual Value Share otherwise issuable upon
conversion that the Company elects to pay in cash, multiplied by (2) the cash value of the Daily Share Amount for such date. The cash value of the Daily Share Amount shall be an amount equal to the product of (A) the Daily Share Amount for such
date, multiplied by (B) the Closing Price of the Common Stock for such date. 
  
 The Company shall not issue fractional shares of Common Stock upon conversion of the Securities. Instead, the Company shall pay the cash value of such fractional shares based upon the Closing Price of the Common Stock
on the Trading Day immediately preceding the Conversion Date. In addition, if the Company chooses to settle all or a portion of the Residual Value Shares in cash in connection with conversions within 20 days prior to Stated Maturity or a specified
Redemption Date, the Company shall send, on or prior to Stated Maturity or the specified Redemption Date, as the case may be, a single notice to the Trustee of the Residual Value Shares to be satisfied in cash. 
  

 62 

 The “Conversion Value” means the product of (1) the Conversion Rate in
effect (plus any Additional Shares as described under Section 10.01(c)) and (2) the average of the Closing Prices of the Common Stock for the Trading Days during the Conversion Reference Period. 
  
 The “Conversion Reference Period” with respect
to any Securities means the 20 consecutive Trading Days beginning on the second Trading Day after the Conversion Date, or if the Company elects to pay cash to Holders in lieu of all or a portion of the Residual Value Shares, the second Trading Day
after the Conversion Retraction Period ends, except in circumstances where conversions occur within 20 days prior to the Stated Maturity or a specified Redemption Date, in which case the Conversion Reference Period will be the 20 consecutive Trading
Days beginning on the fifth Trading Day following the Stated Maturity or the Redemption Date, as the case may be. 
  
 (b) If a Holder tenders Securities for conversion and the Conversion Value is being determined at a time when the Securities are convertible into Exchange
Property, the Conversion Value of each Security shall be determined based on the kind and amount of such Exchange Property and the value thereof during the Conversion Reference Period. Settlement of Securities tendered for conversion after the
effective date of any transaction giving rise to Exchange Property shall be as set forth above. 
  
 For the purposes of this Section, the Closing Price of the Common Stock shall be deemed to equal the sum of (A) 100% of the value of any Exchange Property
consisting of cash received per share of Common Stock, (B) the Closing Price of any Exchange Property received per share of Common Stock consisting of securities that are traded on a U.S. national securities exchange or approved for quotation on the
Nasdaq National Market and (3) the Fair Market Value of any other Exchange Property received per share, as determined by three independent nationally recognized investment banks selected by the Company for this purpose. Settlement (in cash and/or
shares) will occur on the third Business Day following the final day of any Conversion Reference Period. 
  
 Section 10.04. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time, without duplication, by the Company in
accordance with this Section 10.04: 
  
 (a) In case the Company
shall hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion
Rate in effect at the opening of business on the date following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution by a fraction, 
  
 (i) the numerator of which shall be the sum of (A) the
number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus (B) the total number of shares of Common Stock constituting the dividend or distribution; and 
  
 (ii) the denominator of which shall be the number of shares
of Common Stock outstanding at the close of business on the date fixed for such determination, 
  

 63 

 such increase to become effective immediately after the opening of business on the day following the date fixed for such
determination. If any dividend or distribution of the type described in this Section 10.04 is declared but not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate that would then be in effect if such dividend or
distribution had not been declared. 
  
 (b) In case the Company
shall issue rights, warrants or options (other than pursuant to any dividend reinvestment or share repurchase plans) to all holders of its outstanding shares of Common Stock entitling them (for a period expiring within 60 days after the date of such
distribution) to subscribe for or purchase shares of Common Stock at a price per share less than (or having a conversion price per share less than) the Current Market Price on the Trading Day prior to the date upon which such distribution was
publicly announced, the Conversion Rate shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the date fixed for determination of stockholders entitled to receive such
rights, warrants or options by a fraction, 
  
 (i) the numerator of which shall be the sum of (A) the number of shares of Common Stock outstanding on the date fixed for determination of stockholders entitled to receive such rights, warrants or options plus (B) the total number of
additional shares of Common Stock offered for subscription or purchase, and 
  
 (ii) the denominator of which is the sum of (A) the number of shares of Common Stock outstanding on the date fixed for determination of stockholders entitled to receive such rights, warrants or options plus (B) the
total number of additional shares of Common Stock that the aggregate offering price of the total number of shares of Common Stock offered for subscription or purchase would purchase at the Current Market Price of the Common Stock on such date.

  
 Such adjustment shall be successively made whenever any such
rights, warrants or options are issued, and shall become effective immediately after the opening of business on the day following the date fixed for determination of stockholders entitled to receive such rights, warrants or options. To the extent
that shares of Common Stock are not delivered after the expiration of such rights, warrants or options, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustments made upon the issuance of such
rights, warrants or options been made on the basis of delivery of only the number of shares of Common Stock actually delivered. In the event that such rights, warrants or options are not so issued, the Conversion Rate shall again be adjusted to be
the Conversion Rate that would then be in effect if such date fixed for the determination of stockholders entitled to receive such rights, warrants or options had not been fixed. In determining whether any rights, options or warrants entitle the
holders to subscribe for or purchase shares of Common Stock at less than such Current Market Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the
Company for such rights, warrants or options and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. 
  
 (c) In case outstanding shares of Common Stock shall be subdivided into a
greater number of shares of Common Stock, the Conversion Rate in effect at the opening of business on 
  

 64 

 the day following the day upon which such subdivision becomes effective shall be proportionately increased, and
conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such combination becomes
effective shall be proportionately reduced, such increase or reduction, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective.

  
 (d) In case the Company shall, by dividend or otherwise,
distribute to all holders of its Common Stock shares of any class of Capital Stock of the Company or evidences of its indebtedness or assets (including securities, but excluding any rights, options or warrants referred to in Section 10.04(b) and
excluding any dividend or distribution (x) paid exclusively in cash or (y) referred to in Section 10.04(a)) (any of the foregoing hereinafter in this Section 10.04(d) called the “Distributed Assets”), then, in each such case, the
Conversion Rate shall be increased so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect on the Record Date with respect to such distribution by a fraction, 
  
 (i) the numerator of which shall be the Current Market Price
per share of the Common Stock on such Record Date; and 
  
 (ii) the denominator of which shall be the Current Market Price per share of the Common Stock less the Fair Market Value (as determined by the Board of Directors and described in a resolution of the Board of Directors) on the Record Date of
the portion of the Distributed Assets so distributed applicable to one share of Common Stock, 
  
 such adjustment to become effective immediately prior to the opening of business on the day following such Record Date; provided, however, that in the event (1) the then Fair Market Value (as so
determined) of the portion of the Distributed Assets so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price of the Common Stock on such Record Date or (2) the Current Market Price of Common Stock
on the Record Date exceeds the then Fair Market Value (as so determined) of the portion of the Distributed Assets so distributed applicable to one share of Common Stock by less than $1.00, in lieu of the foregoing adjustment, adequate provision
shall be made so that each Holder shall have the right to receive upon conversion the amount of Distributed Assets such Holder would have received had such Holder converted each Security on the Record Date for such distribution. In the event that
such dividend or distribution is not so paid or made, the Conversion Rate shall be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. If the Board of Directors determines the Fair
Market Value of any distribution for purposes of this Section 10.04(d) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the
Current Market Price of the Common Stock. 
  
 Rights, warrants or
options distributed by the Company to all holders of Common Stock entitling the Holders thereof to subscribe for or purchase shares of the Company’s Capital Stock (either initially or under certain circumstances), which rights, warrants or
options, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of 
  

 65 

 future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 10.04 (and no
adjustment to the Conversion Rate under this Section 10.04 shall be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is
required) to the Conversion Rate shall be made under this Section 10.04. If any such right or warrant, including any such existing rights, warrants or options distributed prior to the date of this Indenture, are subject to events, upon the
occurrence of which such rights, warrants or options become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of
distribution and record date with respect to new rights, warrants or options with such rights (and a termination or expiration of the existing rights, warrants or options without exercise by any of the holders thereof). In addition, in the event of
any distribution (or deemed distribution) of rights, warrants or options, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount
for which an adjustment to the Conversion Rate under this Section 10.04 was made, (1) in the case of any such rights, warrants or options that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate
shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder
or holders of Common Stock with respect to such rights, warrants or options (assuming such holder had retained such rights, warrants or options), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the
case of such rights, warrants or options that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued. 
  
 No adjustment of the Conversion Rate shall be made pursuant to this Section
10.04(d) in respect of rights, warrants or options distributed or deemed distributed on any Trigger Event to the extent that such rights, warrants or options are actually distributed, or reserved by the Company for distribution to Holders of
Securities upon conversion by such Holders of Securities to Common Stock. 
  
 For purposes of this Section 10.04(d) and Section 10.04(a) and (b), any dividend or distribution to which this Section 10.04(d) is applicable that also includes shares of Common Stock, or rights, warrants or options
to subscribe for or purchase shares of Common Stock (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences of indebtedness, assets or shares of capital stock other than such shares of Common Stock or rights,
warrants or options (and any Conversion Rate adjustment required by this Section 10.04(d) with respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock or such
rights, warrants or options (and any further Conversion Rate adjustment required by Section 10.04(a) and (b) with respect to such dividend or distribution shall then be made), except: 
  
 (A) the Record Date of such dividend or distribution shall be substituted as “the date fixed for the
determination of stockholders entitled to receive such dividend or other distribution”, “the date fixed for the determination of stockholders entitled to receive such rights, warrants or options” and “the date fixed for such
determination” within the meaning of Section 10.04(a) and (b), and 
  

 66 

 (B) any shares of Common Stock included in such dividend or distribution shall not be
deemed “outstanding at the close of business on the date fixed for such determination” within the meaning of Section 10.04(a). 
  
 If any Distributed Assets requiring any adjustment pursuant to this Section 10.04(d) consists of the Capital Stock, or similar equity interests in, a
Subsidiary or other business unit of the Company which are or in connection with such distribution will be listed or quoted for trading on a U.S. national securities exchange or the Nasdaq National Market, the Conversion Rate in effect immediately
before the close of business on the Record Date fixed for determination of shareholders entitled to receive the distribution shall instead be increased by multiplying the Conversion Rate then in effect by a fraction, (A) the numerator of which is
the sum of (1) the average of the Closing Prices of such distributed security for the 10 Trading Days commencing on and including the fifth Trading Day after the Ex-Dividend Date on the New York Stock Exchange or such other national or regional
exchange or market on which such securities are then listed or quoted plus (2) the average of the Closing Prices of the Common Stock over the same Trading Day period and (B) the denominator of which is such average of the Closing Prices of the
Common Stock for the 10 Trading Days commencing on and including the fifth Trading Day after the Ex-Dividend Date on the New York Stock Exchange or such other national or regional exchange or market on which the securities are then listed or quoted.

  
 (e) In case the Company shall, by dividend or otherwise,
distribute to a all holders of its Common Stock cash (an “Extraordinary Cash Dividend”) (excluding (i) any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company, whether voluntary or
involuntary or (ii) any quarterly cash dividend on the Common Stock to the extent that the aggregate cash dividend per share of the Common Stock in any fiscal quarter does not exceed $0.22 (such amount being the “Dividend Threshold
Amount”); the Dividend Threshold Amount is subject to adjustment in a manner inversely proportionate to adjustments to the Conversion Rate (other than for adjustments due to cash dividends)), then, in such case, the Conversion Rate shall be
increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the close of business on the Record Date for such Extraordinary Cash Dividend by a fraction, 
  
 (i) the numerator of which shall be the Current Market Price
of the Common Stock on such Record Date, and 
  
 (ii) the denominator of which shall be (A) such Current Market Price of the Common Stock minus (B) the amount per share of such dividend or the amount of cash so distributed applicable to one share of Common Stock minus the Dividend
Threshold Amount; if an adjustment is required to be made as a result of a cash distribution that is not a regular quarterly dividend, the Dividend Threshold Amount will be deemed to be zero, 
  
 such adjustment to be effective immediately prior to the opening of business on the day
following such Record Date; provided, however, that in the event the portion of the cash so 
  

 67 

 distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price of the Common
Stock on such Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive upon conversion the amount of cash such Holder would have received had such Holder converted each
Security on such Record Date. In the event that such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been
declared. 
  
 (f) In case a tender or exchange offer, other than
an odd-lot offer, made by the Company or any Subsidiary for all or any portion of the Common Stock shall expire and such tender or exchange offer (as amended upon the expiration thereof) shall require the payment to stockholders of consideration per
share of Common Stock having a Fair Market Value (as determined by the Board of Directors, whose determination shall be conclusive and described in a resolution of the Board of Directors) that as of the last time (the “Expiration
Time”) tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended) exceeds the Closing Price of the Common Stock on the Trading Day next succeeding the Expiration Time, the Conversion Rate shall be
increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the Expiration Time by a fraction, 
  

(i) the numerator of which shall be the sum of (x) the Fair Market Value (determined as aforesaid) of the aggregate consideration
payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed so accepted up to
any such maximum, being referred to as the “Purchased Shares”) and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares) at the Expiration Time and the Closing Price of the Common Stock on
the first Trading Day after the Expiration Time, and 
  
 (ii) the denominator of which shall be the product of the number of shares of Common Stock outstanding (including any Purchased Shares) at the Expiration Time multiplied by the Closing Price of the Common Stock on the first Trading Day
after the Expiration Time, 
  
 such adjustment to become effective immediately
prior to the opening of business on the day following the Expiration Time. In the event that the Company is obligated to purchase shares pursuant to any such tender or exchange offer, but the Company is permanently prevented by applicable law from
effecting any such purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made. 
  
 (g) In case of a tender or exchange offer made by a Person other than the
Company or any Subsidiary for an amount that increases the offeror’s ownership of Common Stock to more than twenty-five percent (25%) of the Common Stock outstanding and shall involve the payment by such Person of consideration per share of
Common Stock having a Fair Market Value (as determined by the Board of Directors, whose determination shall be conclusive, and described in a resolution of the Board of Directors) that as of the last time (the “Offer Expiration
Time”) 
  

 68 

 tenders or exchanges may be made pursuant to such tender or exchange offer (as it shall have been amended) exceeds the
Closing Price of the Common Stock on the first Trading Day after the Offer Expiration Time, and in which, as of the Offer Expiration Time the Board of Directors is not recommending rejection of the offer, the Conversion Rate shall be increased so
that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the Offer Expiration Time by a fraction, 
  
 (i) the numerator of which shall be the sum of (x) the Fair Market Value (determined as aforesaid) of the aggregate consideration payable
to stockholders of the Company based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares of Common Stock validly tendered or exchanged and not withdrawn as of the Offer Expiration Time (the
shares deemed so accepted, up to any such maximum, being referred to as the “Accepted Purchased Shares”) and (y) the product of the number of shares of Common Stock outstanding (less any Accepted Purchased Shares) at the Offer
Expiration Time and the Closing Price of the Common Stock on the first Trading Day after the Offer Expiration Time, and 
  
 (ii) the denominator of which shall be the product of the number of shares of Common Stock outstanding (including any Accepted Purchase
Shares) at the Offer Expiration Time multiplied by the Closing Price of the Common Stock on the first Trading Day after the Offer Expiration Time, 
  
 such adjustment to become effective immediately prior to the opening of business on the day following the Offer Expiration Time. In the event that such Person is
obligated to purchase shares pursuant to any such tender or exchange offer, but such Person is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted
to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made. Notwithstanding the foregoing, the adjustment described in this Section 10.04(g) shall not be made if, as of the Offer Expiration Time, the
offering documents with respect to such offer disclose a plan or intention to cause the Company to engage in any transaction described in Section 10.05. 
  
 (h) The Company may make such increases in the Conversion Rate, in addition to those required by this Section 10.04, as the Board of Directors considers
to be advisable to avoid or diminish any U.S. federal income tax to holders of Common Stock resulting from any dividend or distribution of Capital Stock (or rights to acquire Capital Stock) or any event treated as such for income tax purposes;
provided, however, that such increase in the Conversion Rate shall not adversely affect the interests of the Holders of Securities (after taking into account U.S. federal income tax and other consequences of such increase). 
  
 To the extent permitted by applicable law and the listing requirements of the
New York Stock Exchange or any national securities exchange on which the Common Stock is then listed, the Company from time to time may increase the Conversion Rate by any amount for any period of time if the period is at least twenty (20) days, the
increase is irrevocable during the period and the Board of Directors shall have made a determination that such increase would be in the best interests of the Company, which determination shall be conclusive. Whenever the Conversion Rate is increased
pursuant to the preceding sentence, the Company shall mail to Holders of 
  

 69 

 record of the Securities a notice of the increase at least fifteen (15) days prior to the date the increased Conversion
Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it shall be in effect. 
  
 (i) All calculations under this Article 10 shall be made by the Company and shall be made to the nearest cent or to the nearest one-ten thousandth of a
share, as the case may be, with one half-cent and 0.005 of a share, respectively, being rounded upward. No adjustment to the Conversion Rate shall be required unless the adjustment requires an increase or decrease of at least 1.0% of the Conversion
Rate. However, any adjustments which are not required to be made because they would have required an increase or decrease of less than 1.0% shall be carried forward and be made on the first to occur of (i) any subsequent adjustment, (ii) the first
day of the next calendar year and (iii) upon any conversion of the Securities. Notwithstanding the foregoing, no adjustment need be made for: 
  
 (i) the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or
interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan, 
  
 (ii) the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee,
director or consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries, 
  
 (iii) the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible
security outstanding as of the date the Securities were first issued, 
  
 (iv) a change in the par value of the Common Stock, or 
  
 (v) accrued and unpaid Interest, including Contingent Interest or Additional Amounts, if any. 
  
 To the extent the Securities become convertible into cash,
assets, property or securities (other than Capital Stock of the Company), no adjustment need be made thereafter as to the cash, assets, property or such securities. 
  
 (j) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any
Conversion Agent (if other than the Trustee) an Officer’s Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of
the Trustee shall have received such Officer’s Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume that the last Conversion Rate of which it has knowledge is still in effect.
Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail such notice
of such adjustment of the Conversion Rate to the Holder of each Security at his last address appearing on the Security register provided for in Section 2.03 of this Indenture, within twenty (20) days after execution thereof. Failure to deliver such
notice shall not affect the legality or validity of any such adjustment.

 (k) In any case in which this Section 10.04 provides that an adjustment shall become effective
immediately after (1) a record date or Record Date for an event, (2) the date fixed for the determination of stockholders entitled to receive a dividend or distribution pursuant to Section 10.04(a), (3) a date fixed for the determination of
stockholders entitled to receive rights, warrants or options pursuant to Section 10.04(b), (4) the effective date of any subdivision or combination of Common Stock, (5) the Expiration Time for any tender or exchange offer pursuant to Section
10.04(f), or (6) the Offer Expiration Time for a tender offer or exchange offer pursuant to Section 10.04(g) (each a “Determination Date”), the Company may elect to defer until the occurrence of the relevant Adjustment Event (as
hereinafter defined) (x) issuing to the Holder of any Security converted after such Determination Date and before the occurrence of such Adjustment Event, the additional shares of Common Stock or other securities issuable upon such conversion by
reason of the adjustment required by such Adjustment Event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment and (y) paying to such Holder any amount in cash in lieu of any fraction pursuant to
Section 10.04(a). For purposes of this Section 10.04(k), the term “Adjustment Event” shall mean: 
  
 (i) in any case referred to in clause (1) hereof, the occurrence of such event, 
  
 (ii) in any case referred to in clause (2) hereof, the date
any such dividend or distribution is paid or made, 
  
 (iii) in any case referred to in clause (3) hereof, the date of expiration of such rights, warrants or options, 
  
 (iv) in any case referred to in clause (4) hereof, the date of such subdivision or combination, and 
  
 (v) in any case referred to in clause (5) or clause (6)
hereof, the date a sale or exchange of Common Stock pursuant to such tender or exchange offer is consummated and becomes irrevocable. 
  
 (l) For purposes of this Section 10.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the
Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company shall not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the
Company. 
  
 Section 10.05. Effect of Reclassification,
Consolidation, Merger or Sale. (a) If any of the following events occur, namely (i) any reclassification or change of the outstanding shares of Common Stock (other than a subdivision or combination to which Section 10.04(c) applies or a change
in par value), (ii) any consolidation, merger, binding share exchange or combination of the Company with another Person as a result of which holders of Common Stock shall be entitled to receive Exchange Property with respect to or in exchange for
such Common Stock, or (iii) any sale or conveyance of all or substantially all the properties and assets of the Company to any other Person, in each case, as a result of which holders of Common Stock shall 
  

 71 

 be entitled to receive Exchange Property with respect to or in exchange for such Common Stock, then the Company or the
successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture) providing for the
conversion and settlement of the Securities as set forth in this Indenture. Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 10. If,
in the case of any such reclassification, change, merger, consolidation, binding share exchange, combination, sale or conveyance, the Exchange Property receivable thereupon by a holder of Common Stock includes shares of stock or other securities and
assets of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change, merger, consolidation, binding share exchange, combination, sale or conveyance, then such supplemental indenture shall
also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors shall reasonably consider necessary by reason of the foregoing. 

 
 (b) The Conversion Obligation with respect to each $1,000 principal amount
of Securities converted following the effective date of any such transaction, shall be calculated (as provided in clause (c) below) based on the Exchange Property assuming such holder of Common Stock did not exercise his rights of election, if any,
as to the kind or amount of Exchange Property receivable upon such consolidation, merger, binding share exchange, sale or conveyance (provided that, if the Exchange Property receivable upon such consolidation, merger, binding share exchange,
sale or conveyance is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised (“Non-Electing Share”), then for the purposes of this Section 10.05 the Exchange Property
receivable upon such consolidation, merger, binding share exchange, sale or conveyance for each Non- Electing Share shall be deemed to be the kind and amount so receivable per share by a plurality of the Non-Electing Shares). 
  
 (c) The Conversion Obligation in respect of any Securities converted
following the effective date of any such transaction shall be computed in the same manner as set forth in Section 10.03(a) and, if the Securities become convertible into Exchange Property, Section 10.03(b), provided, that any amount of the
Conversion Settlement Distribution to be delivered in shares of Common Stock shall be paid in Exchange Property rather than shares of Common Stock. If the Exchange Property includes more than one kind of property, the amount of Exchange Property of
each kind to be delivered shall be in the proportion that the value of the Exchange Property (as calculated pursuant to Section 10.03) of such kind bears to the value of all such Exchange Property. If the foregoing calculations would require the
Company to deliver a fractional share or unit of Exchange Property to a Holder of Securities being converted, the Company shall deliver cash in lieu of such fractional share or unit based on the value of the Exchange Property. 
  
 (d) The Company shall cause notice of the execution of such supplemental
indenture to be mailed to each Holder of Securities, at its address appearing on the Security register provided for in Section 2.03 of this Indenture, within twenty (20) days after execution thereof. Failure to deliver such notice shall not affect
the legality or validity of such supplemental indenture. 
  

 72 

 (e) The above provisions of this Section shall similarly apply to successive reclassifications, changes,
consolidations, mergers, binding share exchanges, combinations, sales and conveyances. If this Section 10.05 applies to any event or occurrence, Section 10.04 shall not apply. 
  
 Section 10.06. Taxes on Shares Issued. The issue of stock certificates on conversions of Securities shall be made
without charge to the converting Holder for any documentary, stamp or similar issue or transfer tax in respect of the issue thereof, except for applicable withholding, if any. The Company shall not, however, be required to pay any tax or duty which
may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the Holder of any Securities converted, and the Company shall not be required to issue or deliver any such stock certificate unless
and until the Person or Persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. 
  
 Section 10.07. Reservation of Shares, Shares to Be Fully Paid;
Compliance with Governmental Requirements; Listing of Common Stock. (a) The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock for the
conversion of the Securities from time to time as such Securities are presented for conversion. 
  
 (b) Before taking any action which would cause an adjustment increasing the Conversion Rate to an amount that would cause the Conversion Price to be
reduced below the then par value, if any, of the shares of Common Stock issuable upon conversion of the Securities, the Company shall take all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may
validly and legally issue shares of such Common Stock at such adjusted Conversion Rate. 
  
 (c) (i) The Company covenants that all shares of Common Stock which may be issued upon conversion of Securities shall upon issue be fully paid and nonassessable by the Company and free from all taxes, liens and
charges with respect to the issue thereof. 
  
 (ii) The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Securities hereunder require registration with or approval of any governmental authority under any federal or state law before
such shares may be validly issued upon conversion, the Company shall in good faith and as expeditiously as possible, to the extent then permitted by the rules and interpretations of the Securities and Exchange Commission (or any successor thereto),
endeavor to secure such registration or approval, as the case may be. 
  
 Section 10.08. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty responsibility to any Holder of Securities to determine the Conversion Rate or whether any facts exist which
may require any adjustment of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed,
in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of 
  

 73 

 Common Stock, or of any securities or property, which may at any time be issued or delivered upon the conversion of any
Security; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of
Common Stock or stock certificates or other securities or property or cash upon the surrender of any Security for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article
10. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to
Section 10.05 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Securities after any event referred to in such Section 10.05 or to any adjustment to
be made with respect thereto, but, subject to the provisions of Section 7.01, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in conclusively relying upon the Officer’s Certificate (which the
Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. 
  
 Section 10.09. Notice to Holders Prior to Certain Actions. In case: 
  
 (a) the Company shall declare a dividend (or any other distribution) on its Common Stock that would require
an adjustment in the Conversion Rate pursuant to Section 10.04; or 
  
 (b) the Company shall authorize the granting to the holders of all of its Common Stock of rights, warrants or options to subscribe for or purchase any share of any class or any other rights, warrants or options that
would require an adjustment in the Conversion Rate pursuant to Section 10.04(b); or 
  
 (c) of any reclassification or reorganization of the Common Stock of the Company (other than a subdivision or combination of its
outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation, merger or binding share exchange to which the Company is a party and for which approval of any
stockholders of the Company is required, or of the sale or transfer of all or substantially all of the assets of the Company; or 
  
 (d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; 
  
 the Company shall cause to be filed with the Trustee and to be mailed to each Holder of
Securities at his address appearing on the register provided for in Section 2.03 of this Indenture, as promptly as possible but in any event at least ten (10) days prior to the applicable date hereinafter specified, a notice stating (x) the date on
which a record is to be taken for the purpose of such dividend, distribution of rights, warrants or options, or, if a record is not to be taken, the date as of which the Holders of Common Stock of record to be entitled to such dividend, distribution
or rights are to be determined, or (y) the date on which such reclassification, consolidation, merger, or binding share exchange, sale, transfer, dissolution, liquidation or winding up is expected to become effective or occur, and the date as of
which it is expected that 
  

 74 

 holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property
deliverable upon such reclassification, consolidation, merger, or binding share exchange, sale, transfer, dissolution, liquidation or winding up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such
dividend, distribution, reclassification, consolidation, merger, or binding share exchange, sale, transfer, dissolution, liquidation or winding up. 
  
 Section 10.10. Shareholder Rights Plan. To the extent that the Company has a rights plan in effect upon conversion of the Securities into Common
Stock, a Holder who converts securities shall receive, in addition to the Common Stock, the rights under the rights plan, unless prior to any conversion, the rights have separated from the Common Stock, in which case the Conversion Rate shall be
adjusted at the time of separation as if the Company distributed to all Holders of Common Stock, shares of the Company’s Capital Stock, evidences of indebtedness or assets as described in Section 10.04(d) above, subject to readjustment in the
event of the expiration, termination or redemption of such rights. In lieu of any such adjustment, the Company may amend such applicable shareholder rights agreement to provide that upon conversion of the Securities the Holders shall receive, in
addition to the Common Stock issuable upon such conversion, the rights which would have attached to such Common Stock if the rights had not become separated from the Common Stock under such applicable shareholder rights agreement. 
  
 Section 10.11. Unconditional Right of Holders to Convert.
Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to convert its Security in accordance with this Article 10 and to bring an action for the enforcement of any
such right to convert, and such rights shall not be impaired or affected without the consent of such Holder; provided, however, that the right of any Holder to receive cash upon conversion of any Security shall be subject to the subordination
provisions of Article 11. 
  
 ARTICLE 11 
 SUBORDINATION 
  
 Section 11.01. Agreement to Subordinate. The Company covenants and agrees, and each Securityholder by accepting a Security likewise covenants and
agrees, that all Securities shall be issued subject to the provisions of this Article 11; and each Person holding any Security, whether upon original issue or upon transfer, assignment or exchange thereof, accepts and agrees to be bound by such
provisions. 
  
 The payment of the principal of, premium, if any,
Interest, Contingent Interest and Additional Amounts, if any, on all Securities (including, but not limited to, the Redemption Price with respect to the Securities called for redemption or the Fundamental Change Repurchase Price or the Repurchase
Price with respect to the Securities subject to repurchase in accordance with Article 3 as provided in this Indenture) issued hereunder shall, to the extent and in the manner hereinafter set forth, be subordinated and subject in right of payment to
the prior payment of all Senior Indebtedness, whether outstanding at the date of this Indenture or thereafter incurred, in full in cash or payment satisfactory to the holders of Senior Indebtedness. 
  

 75 

 No provision of this Article 11 shall prevent the occurrence of any Default or Event of Default
hereunder. 
  
 Section 11.02. Payment to Securityholders.
No payment shall be made with respect to the principal of, or premium, if any, Interest, Contingent Interest and Additional Amounts, if any, on the Securities (including, but not limited to, the Redemption Price with respect to the Securities called
for redemption or the Fundamental Change Repurchase Price or the Repurchase Price with respect to the Securities subject to repurchase in accordance with Article 3 as provided in this Indenture), and no redemption, repurchase or retirement of the
Securities shall occur and no deposit shall be made pursuant to Article 8 at a time when such deposited amounts would otherwise be permitted under this Article 11, other than through the delivery of Common Stock (but not the cash portion of the
Company’s conversion obligation) in respect of the conversion of Securities if: 
  
 (a) a default in the payment of principal, premium, interest, rent or other obligations due on any Senior Indebtedness occurs and is
continuing (or, in the case of Senior Indebtedness for which there is a period of grace, in the event of such a default that continues beyond the period of grace, if any, specified in the instrument or lease evidencing such Senior Indebtedness),
unless and until such default shall have been cured or waived by the appropriate holders of the Senior Indebtedness or shall have ceased to exist; or 
  
 (b) a default, other than a payment default, on any Designated Senior Indebtedness occurs and is continuing that then permits holders of
such Designated Senior Indebtedness to accelerate the maturity of all or any portion of such Designated Senior Indebtedness (or would permit such holders to so accelerate with the giving of notice or the passage of time or both) and the Trustee
receives a notice of the default (a “Payment Blockage Notice”) from a Representative or holder of such Designated Senior Indebtedness or the Company. 
  
 Subject to the provisions of Section 11.05, if the Trustee receives any Payment Blockage Notice pursuant to clause (b)
above, no subsequent Payment Blockage Notice shall be effective for purposes of this Section unless and until at least 360 days shall have elapsed since the initial effectiveness of the immediately prior Payment Blockage Notice. No nonpayment
default that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Trustee (unless such default was waived, cured or otherwise ceased to exist and thereafter subsequently reoccurred) shall be, or be made, the basis
for a subsequent Payment Blockage Notice, whether or not within a period of 360 consecutive days. 
  
 Unless this Article 11 otherwise prohibits payments on or distributions in respect of the Securities at the time of such payments or distributions, the
Company may and shall resume such payments on and distributions: 
  
 (A) in the case of a default referred to in clause (a) above, the date upon which the default is cured or waived by the requisite holders of Senior Indebtedness or otherwise ceases to exist, or 
  

 76 

 (B) in the case of a default referred to in clause (b) above, the earliest to occur of
(i) the date on which such default is cured or waived or otherwise ceases to exist or such Designated Senior Indebtedness is discharged or paid in full, (ii)179 days pass after the date on which the applicable Payment Blockage Notice is received,
and (iii) such payment blockage period shall have been terminated by written notice to the Company or the Trustee from the Person initiating such payment blockage period, if the maturity of such Designated Senior Indebtedness has not been
accelerated. 
  
 Upon any payment by the Company, or distribution
of assets of the Company of any kind or character, whether in cash, property or securities, to creditors upon any dissolution or winding-up or liquidation or reorganization of the Company (whether voluntary or involuntary) or in bankruptcy,
insolvency, receivership or similar proceedings, all amounts due or to become due upon all Senior Indebtedness shall first be paid in full in cash, or other payment satisfactory to the holders of Senior Indebtedness before any payment is made on
account of the principal of, premium, if any, Interest, Contingent Interest or Additional Amounts, if any, on the Securities (including, but not limited to, the Redemption Price with respect to the Securities called for redemption or the Fundamental
Change Repurchase Price or the Repurchase Price with respect to the Securities subject to repurchase in accordance with Article 3 as provided in this Indenture); and upon any such dissolution or winding-up or liquidation or reorganization of the
Company or bankruptcy, insolvency, receivership or other proceeding, any payment by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the Securityholders or the Trustee
would be entitled, except for the provision of this Article 11, shall (except as aforesaid) be paid by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, or by the
Securityholders or by the Trustee under this Indenture if received by them or it, directly to the holders of Senior Indebtedness (pro rata to such holders on the basis of the respective amounts of Senior Indebtedness held by such holders, or as
otherwise required by law or a court order) or their Representative or Representatives, as their respective interests may appear, to the extent necessary to pay all Senior Indebtedness in full in cash, or other payment satisfactory to the holders of
Senior Indebtedness, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness, before any payment or distribution is made to the Securityholders or to the Trustee. 
  
 For purposes of this Article 11, the words, “cash, property or
securities” shall not be deemed to include shares of stock of the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment, the payment of which is
subordinated at least to the extent provided in this Article 11 with respect to the Securities to the payment of all Senior Indebtedness which may at the time be outstanding; provided that (i) the Senior Indebtedness is assumed by the new
corporation, if any, resulting from any reorganization or readjustment, and (ii) the rights of the holders of Senior Indebtedness (other than leases which are not assumed by the Company or the new corporation, as the case may be) are not, without
the consent of such holders, altered by such reorganization or readjustment. The consolidation of the Company with, or the merger of the Company into, another corporation or the liquidation or dissolution of the Company following the conveyance,
transfer, sale, lease or other disposition of its property as an entirety, or substantially as an 
  

 77 

 entirety, to another corporation upon the terms and conditions provided for in Article 5 shall not be deemed a
dissolution, winding-up, liquidation or reorganization for the purposes of this Section 11.02 if such other corporation shall, as a part of such consolidation, merger, conveyance, transfer, sale, lease or other disposition, comply with the
conditions stated in Article 5. 
  
 In the event of the
acceleration of the Securities because of an Event of Default, no payment or distribution shall be made to the Trustee or any Securityholders in respect of the principal of, premium, if any, Interest, Contingent Interest or Additional Amounts, if
any, on the Securities by the Company (including, but not limited to, the Redemption Price with respect to the Securities called for redemption or the Fundamental Change Repurchase Price or the Repurchase Price with respect to the Securities subject
to repurchase in accordance with Article 3 as provided in this Indenture), except payments and distributions made by the Trustee as permitted by Section 11.05, until all Senior Indebtedness has been paid in full in cash or other payment satisfactory
to the holders of Senior Indebtedness or such acceleration is rescinded in accordance with the terms of this Indenture. If payment of the Securities is accelerated because of an Event of Default, the Company shall promptly notify holders of Senior
Indebtedness of such acceleration. 
  
 In the event that,
notwithstanding the foregoing provisions, any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities (including, without limitation, by way of setoff or otherwise), prohibited by the
provisions of this Article 11, shall be received by the Trustee or any of the Securityholders before all Senior Indebtedness is paid in full, in cash or other payment satisfactory to the holders of Senior Indebtedness, or provision is made for such
payment thereof in accordance with its terms in cash or other payment satisfactory to the holders of Senior Indebtedness, such payment or distribution shall be held in trust for the benefit of and shall be paid over or delivered to the holders of
Senior Indebtedness or their Representative or Representatives, as their respective interests may appear, as calculated by the Company. 
  
 Nothing in this Section 11.02 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 7.07. This Section 11.02 shall be subject
to the further provisions of Section 11.05. 
  
 Section 11.03.
Subrogation of Securities. After the payment in full, in cash or other payment satisfactory to the holders of Senior Indebtedness of all Senior Indebtedness (and all commitments with respect to such Senior Indebtedness have terminated or
expired), the rights of the Securityholders shall be subrogated to the extent of the payments or distributions made to the holders of such Senior Indebtedness pursuant to the provisions of this Article 11 (equally and ratably with the holders of all
indebtedness of the Company which by its express terms is subordinated to other indebtedness of the Company to substantially the same extent as the Securities are subordinated and is entitled to like rights of subrogation) to the rights of the
holders of Senior Indebtedness to receive payments or distributions of cash, property or securities of the Company applicable to the Senior Indebtedness until the principal, premium, if any, Interest, Contingent Interest or Additional Amounts, if
any, on the Securities shall be paid in full in cash or other payment satisfactory to the holders of Senior Indebtedness; and, for the purposes of such subrogation, no payments or distributions to the holders of the Senior 
  

 78 

 Indebtedness of any cash, property or securities to which the Securityholders or the Trustee would be entitled except for
the provisions of this Article 11, and no payment over pursuant to the provisions of this Article 11, to or for the benefit of the holders of Senior Indebtedness by Securityholders or the Trustee, shall, as between the Company, its creditors other
than holders of Senior Indebtedness, and the Securityholders, be deemed to be a payment by the Company to or on account of the Senior Indebtedness; and no payments or distributions of cash, property or securities to or for the benefit of the
Securityholders pursuant to the subrogation provisions of this Article 11, which would otherwise have been paid to the holders of Senior Indebtedness shall be deemed to be a payment by the Company to or for the account of the Securities. It is
understood that the provisions of this Article 11 are and are intended solely for the purposes of defining the relative rights of the Securityholders, on the one hand, and the holders of the Senior Indebtedness, on the other hand. 
  
 Nothing contained in this Article 11 or elsewhere in this Indenture or in the
Securities is intended to or shall impair, as among the Company, its creditors other than the holders of Senior Indebtedness, and the Securityholders, the obligation of the Company, which is absolute and unconditional, to pay to the Securityholders
the principal of (and premium, if any), Interest, Contingent Interest or Additional Amounts, if any, on the Securities as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative
rights of the Securityholders and creditors of the Company other than the holders of the Senior Indebtedness, nor shall anything herein or therein prevent the Trustee or the Securityholders from exercising all remedies otherwise permitted by
applicable law upon Default under this Indenture, subject to the rights, if any, under this Article 11 of the holders of Senior Indebtedness in respect of cash, property or securities of the Company received upon the exercise of any such remedy.

  
 Upon any payment or distribution of assets of the Company
referred to in this Article 11, the Trustee, subject to the provisions of Section 7.01, and the Securityholders shall be entitled to conclusively rely upon any order or decree made by any court of competent jurisdiction in which such bankruptcy,
dissolution, winding-up, liquidation or reorganization proceedings are pending, or a certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, delivered to the Trustee or to
the Securityholders, for the purpose of ascertaining the Persons entitled to participate in such distribution, the holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon and all other facts
pertinent thereto or to this Article 11. 
  
 Section 11.04.
Authorization to Effect Subordination. Each Securityholder by accepting a Security authorizes and directs the Trustee on such holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination as
provided in this Article 11 and appoints the Trustee to act as such holder’s attorney-in-fact for any and all such purposes. If the Trustee does not file a proper proof of claim or proof of debt in the form required in any proceeding referred
to in Section 11.03 hereof at least 30 days before the expiration of the time to file such claim, the holders of any Senior Indebtedness or their Representatives are hereby authorized to file an appropriate claim for and on behalf of the
Securityholders and each Securityholder hereby appoints the holders of Senior Indebtedness or their respective Representatives to act as its attorney-in-fact for any and all such purposes. 
  

 79 

 Section 11.05. Notice to Trustee. The Company shall give prompt written notice in the form of an
Officer’s Certificate to a Responsible Officer of the Trustee and to any Paying Agent of any fact known to the Company which would prohibit the making of any payment of monies to or by the Trustee or any Paying Agent in respect of the
Securities pursuant to the provisions of this Article 11. Notwithstanding the provisions of this Article 11 or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which would prohibit
the making of any payment of monies to or by the Trustee in respect of the Securities pursuant to the provisions of this Article 11, unless and until a Responsible Officer of the Trustee shall have received written notice thereof at the office of
the Trustee specified in Section 13.02 hereof from the Company (in the form of an Officer’s Certificate) or a Representative or a holder or holders of Senior Indebtedness; and before the receipt of any such written notice, the Trustee, subject
to the provisions of Section 7.01, shall be entitled in all respects to assume that no such facts exist; provided that with respect to any such monies that may become payable for any purpose (including, without limitation, the payment of the
principal of, or premium, if any, or Interest on any Security) unless the Trustee shall have received, on a date not less than one Business Day immediately prior to the date upon which by the terms hereof such monies shall become payable, the notice
provided for in this Section 11.05, then, anything in the first two paragraphs of Section 11.02 contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such monies and to apply the same to the purpose
for which they were received, and shall not be affected by any notice to the contrary which may be received by it on or after such prior date; provided further that if the Trustee shall receive any such notice on the date upon which by the
terms hereof such monies shall become payable, the Trustee may, in its reasonable discretion, waive the time for notice provided in the foregoing proviso. Nothing shall prevent any payment by the Trustee to the holders of monies deposited with it
pursuant to Article 8, and any such payment shall not be subject to the provisions of Article 11; provided that, at the time of any such deposit, such deposit and payment were permitted under this Article 11 without giving effect to the first clause
of this sentence. 
  
 The Trustee, subject to the provisions of
Section 7.01, shall be entitled to conclusively rely on the delivery to it of a written notice by a Representative or a Person representing himself to be a holder of Senior Indebtedness to establish that such notice has been given by a
Representative or a holder of Senior Indebtedness. In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of Senior Indebtedness to participate in any payment or
distribution pursuant to this Article 11, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such Person, the extent to which such Person is entitled
to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article 11, and if such evidence is not furnished the Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment. 
  
 Section
11.06. Trustee’s Relation to Senior Indebtedness. The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article 11 in respect of any Senior Indebtedness at any time held by it, to the same extent as
any other holder of Senior Indebtedness, and nothing in Section 7.11 or elsewhere in this Indenture shall deprive the Trustee of any of its rights as such holder. Nothing in this Article 11 shall apply to the claims of, or payment to, the Trustee
under or pursuant to Section 7.07. 
  

 80 

 With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only
such of its covenants and obligations as are specifically set forth in this Article 11, and no implied covenants or obligations with respect to the holders of Senior Indebtedness shall be read into this Indenture against the Trustee. The Trustee
shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and, subject to the provisions of Section 7.01, the Trustee shall not be liable to any holder of Senior Indebtedness if it shall pay over or deliver to
Securityholders, the Company or any other Person money or assets to which any holder of Senior Indebtedness shall be entitled by virtue of this Article 11 or otherwise. 
  
 Section 11.07. No Impairment of Subordination. No right of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by
the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof which any such holder may have or otherwise be charged with. 
  
 Section 11.08. Certain Conversions Deemed Payment. For the purposes of this Article 11 only, (a) the issuance and
delivery of Junior Securities upon conversion of Securities in accordance with Article 10 shall not be deemed to constitute a payment or distribution on account of the principal of (or premium, if any), Interest, Contingent Interest or Additional
Amounts, if any, on the Securities or on account of the purchase or other acquisition of Securities, and (b) the payment, issuance or delivery of cash (except in satisfaction of fractional shares), securities (other than Junior Securities) or other
property upon conversion of a Security shall be deemed to constitute payment on account of the principal of such Security, the payment, issuance and delivery of such cash being made subject to the subordination provisions of this Article 11. For the
purposes of this Section 11.08, the term “Junior Securities” means (1) shares of any stock of any class of the Company or (2) securities of the Company which are subordinated in right of payment to all Senior
Indebtedness which may be outstanding at the time of issuance or delivery of such securities to substantially the same extent as, or to a greater extent than, the Securities are so subordinated as provided in this Article 11. Nothing contained in
this Article 11 or elsewhere in this Indenture or in the Securities is intended to or shall impair, as among the Company, its creditors other than holders of Senior Indebtedness and the Securityholders, the right, which is absolute and
unconditional, of the Securityholders to convert such Securities in accordance with Article 10. 
  
 Section 11.09. Article Applicable to Paying Agents. If at any time any Paying Agent other than the Trustee shall have been appointed by the Company
and be then acting hereunder, the term “Trustee” as used in this Article shall (unless the context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as
if such Paying Agent were named in this Article in addition to or in place of the Trustee; provided, however, that the first paragraph of Section 11.05 shall not apply to the Company or any Affiliate of the Company if it or such
Affiliate acts as Paying Agent. 
  

 81 

 Section 11.10. Senior Indebtedness Entitled to Rely. The holders of Senior Indebtedness shall have
the right to rely upon this Article 11, and no amendment or modification of the provisions of this Article 11 that adversely affect the rights and interests of such holders shall be effective as to such holders unless such holders shall have agreed
in writing thereto. Each Securityholder by accepting a Security acknowledges and agrees that the provisions of Article 11 are, and are intended to be, an inducement and consideration to each holder of Senior Indebtedness (whether such Senior
Indebtedness was acquired or created before or after the issuance of the Securities) to acquire and hold, or to continue to hold, such Senior Indebtedness, and such holder of Senior Indebtedness shall be deemed conclusively to have relied on the
provisions of this Article 11 in acquiring and continuing to hold such Senior Indebtedness. 
  
 Section 11.11. Reinstatement. To the extent the payment of or distribution in respect of any Senior Indebtedness (whether by or on behalf of the Company as proceeds of security or enforcement of any right of
setoff or otherwise) is declared to be fraudulent or preferential, set aside or required to be paid to any receiver, trustee in bankruptcy, liquidating trustee, agent or similar Person under any bankruptcy, insolvency, receivership, fraudulent
conveyance or similar law, then if such payment or distribution is recovered by, or paid over to, such receiver, trustee in bankruptcy, liquidating trustee, agent or similar Person, the Senior Indebtedness or part thereof originally intended to be
satisfied shall be deemed to be reinstated and outstanding as if such payment had not occurred. 
  
 Section 11.12. Actions by Holders of Senior Indebtedness. The holders of the Senior Indebtedness may, at any time and from time to time, without
the consent of or notice to the Trustee or the Securityholders, without incurring responsibility to the Securityholders and without impairing or releasing the subordination provided in this Indenture or the obligations of the Securityholders
hereunder to the holders of the Senior Indebtedness, do any one or more of the following: 
  
 (a) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, the Senior Indebtedness or any
instrument evidencing the same or any agreement under which any Senior Indebtedness is outstanding or secured; 
  
 (b) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise secured; 
  
 (c) release any Person liable in any manner for the
collection of Senior Indebtedness; 
  
 (d)
exercise or refrain from exercising any rights against the Company or any other Person; and 
  
 (e) take any other action in the reasonable business judgment of the holders of Senior Indebtedness.

 [FORM OF REVERSE OF GLOBAL SECURITY] 
  
 3.75% Convertible Senior Subordinated Notes Due 2025 
  
 This Security is one of a duly authorized issue of 3.75% Convertible Senior Subordinated Notes Due 2025 (the
“Securities”) of Barnes Group Inc., a Delaware corporation (including any successor corporation under the Indenture hereinafter referred to, the “Company”), issued under an Indenture,
dated as of August 1, 2005 (the “Indenture”), between the Company and The Bank of New York Trust Company, N.A., as trustee (the “Trustee”). The terms of the Security include those stated
in the Indenture, those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (“TIA”), and those set forth in this Security. This Security is subject to all such terms, and Holders are
referred to the Indenture and the TIA for a statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Security and the terms of the Indenture, the terms of the Indenture shall
control. Capitalized terms used but not defined herein have the meanings assigned to them in the Indenture unless otherwise indicated. 
  
 1. Interest. 
  
 The Securities shall bear interest on the principal amount thereof at a rate of 3.75% per year. The Company shall pay Contingent Interest, if any, as set
forth in the Indenture and in Section 3 hereof. The Company shall also pay Additional Amounts, if any, as set forth in Section 4.07 of the Indenture and the Registration Rights Agreement. 
  
 Interest shall be payable semi-annually in arrears on each Interest Payment Date to Holders at the close of business on the
preceding Interest Record Date. Interest shall be computed on the basis of a 360-day year comprised of twelve 30-day months. 
  
 The Company shall pay Interest to the Securityholder of record on the Interest Record Date even if the Company elects to redeem or Securityholders elect
to require the Company to repurchase, the Securities on a date that is after an Interest Record Date but on or prior to the corresponding Interest Payment Date. In that instance, the Company shall pay accrued and unpaid Interest on the Securities
being redeemed to, but not including, the Redemption Date, the Repurchase Date or the Fundamental Change Repurchase Date, as the case may be, to the Securityholder of record on the Interest Record Date. 
  
 If the principal amount of any Security, or any accrued and unpaid Interest,
Contingent Interest, if any, or Additional Amounts, if any, are not paid when due (whether upon acceleration pursuant to Section 6.02 of the Indenture, upon the date set for payment of the Redemption Price pursuant to Section 5 hereof, upon the date
set for payment of the Repurchase Price or Fundamental Change Repurchase Price pursuant to Section 6 hereof, upon the Stated Maturity of the Securities, upon the Interest Payment Dates or upon the Additional Amounts Payment Dates (as defined in the
Registration Rights Agreement), then in each such case the overdue amount shall, to the extent permitted by law, bear cash interest at the rate of 3.75% per annum, compounded semiannually, which interest shall accrue from the date such overdue
amount was originally due to the date payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be payable in cash on demand but if not so demanded shall be paid quarterly to the Holders on the
last day of each quarter. 
  

 A-5 

 2. Method of Payment. 
  
 Except as provided below, the Company shall pay Interest, including Contingent Interest, if any, and Additional Amounts, if any, on (i) Global Securities,
to DTC, or its nominee, as the case may be, as the registered owner thereof, in immediately available funds, (ii) any Certificated Security having an aggregate principal amount of $2,000,000 or less, by check mailed to the Holder of such Security
and (iii) any Certificated Security having an aggregate principal amount of more than $2,000,000, by wire transfer in immediately available funds if requested by the Holder of any such Security as least five business days prior to the relevant
Interest Payment Date. 
  
 At Stated Maturity, the Company shall
pay Interest on Certificated Securities at the Company’s office or agency maintained for that purpose, which initially shall be the office or agency of the Trustee located in the Borough of Manhattan, The City of New York. 
  
 Subject to the terms and conditions of the Indenture, the Company shall make
payments in cash in respect of Redemption Prices, Repurchase Prices, Fundamental Change Repurchase Prices and at Stated Maturity to Holders who surrender Securities to a Paying Agent to collect such payments in respect of the Securities. The Company
shall pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. However, the Company may make such cash payments by check payable in such money. 
  
 3. Contingent Interest 
  
 The Company shall pay Contingent Interest under the circumstances and in the amounts described in Article 12 of the
Indenture. Such Contingent Interest, if any, shall be payable in the same manner, at the same time, and subject to the same restrictions, including those restrictions in respect of accrued and unpaid interest on any Securities that are submitted for
conversion, as payments of Interest. 
  
 4. Indenture. 
  
 The Securities are general unsecured obligations of the Company limited to
$100,000,000 aggregate principal amount. The Indenture does not limit other indebtedness of the Company, secured or unsecured. 
  
 5. Redemption at the Option of the Company. 
  
 No sinking fund is provided for the Securities. The Securities are redeemable for cash at the option of the Company, in whole or in part, at any time or
from time to time on or after February 7, 2011 upon not less than 30 nor more than 60 days’ notice by mail for a redemption price (the “Redemption Price”) equal to the principal amount of those Securities plus accrued and
unpaid Interest, accrued and unpaid Contingent Interest, if any, and Additional Amounts, if any, on those Securities up to, but not including, the Redemption Date. 
  

 A-6 

 In no event shall any Security be redeemable before February 7, 2011. 
  
 6. 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 repurchase, at the option of the Holder, all or any portion of the Securities held by such Holder on February 1, 2011, February 1, 2016 and February 1, 2021 in integral multiples of $1,000 at a Repurchase Price equal to 100% of
the principal amount of those Securities plus accrued and unpaid Interest, accrued and unpaid Contingent Interest, if any, and Additional Amounts, if any, on those Securities up to, but not including, the Repurchase Date. To exercise such right, a
Holder shall deliver to the Paying Agent a Repurchase Notice containing the information set forth in the Indenture, at any time from the opening of business on the date that is 20 Business Days prior to such Repurchase Date until the close of
business on the Repurchase Date, and shall deliver the Securities to the Paying Agent as set forth in the Indenture. 
  
 At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to repurchase the Securities held
by such Holder after the occurrence of a Fundamental Change for a Fundamental Change Repurchase Price equal to the principal amount of those Securities plus accrued and unpaid Interest, accrued and unpaid Contingent Interest, if any, and Additional
Amounts, if any, on those Securities up to, but not including, the Fundamental Change Repurchase Date. 
  
 Holders have the right to withdraw any Repurchase Notice or Fundamental Change Repurchase Notice, as the case may be, by delivering to the Paying Agent a
written notice of withdrawal in accordance with the provisions of the Indenture. 
  
 If cash sufficient to pay the Repurchase Price or Fundamental Change Repurchase Price, as the case may be, of all Securities or portions thereof to be purchased as of the Repurchase Date or the Fundamental Change
Repurchase Date, as the case may be, is deposited with the Paying Agent, Interest, Contingent Interest, if any, and Additional Amounts, if any, shall cease to accrue on such Securities (or portions thereof) on and following such Repurchase Date or
Fundamental Change Repurchase Date, and the Holder thereof shall have no other rights as such other than the right to receive the Repurchase Price or Fundamental Change Repurchase Price upon surrender of such Security. 
  
 7. Notice of Redemption. 
  
 Notice of redemption pursuant to Section 5 of this Security shall be mailed
at least 30 days but not more than 60 days before the Redemption Date to each Holder of Securities to be redeemed at the Holder’s registered address. If money sufficient to pay the Redemption Price of all Securities (or portions thereof) to be
redeemed on the Redemption Date is deposited with the Paying Agent prior to or on the Redemption Date, immediately on and after such Redemption Date Interest, Contingent Interest, if any, and Additional Amounts, if any, shall cease to accrue on such
Securities or portions thereof. Securities in denominations larger than $1,000 principal amount may be redeemed in part but only in integral multiples of $1,000 of principal amount.

 8. Conversion. 
  
 Subject to the occurrence of certain events and in compliance with the provisions of the Indenture (including, without limitation, the conditions to
conversion of this Security set forth in Section 10.01 thereof), a Holder is entitled, at such Holder’s option, to convert the Holder’s Security (or any portion of the principal amount thereof that is $1,000 or an integral multiple of
$1,000), into cash or a combination of cash and fully paid and nonassessable shares of Common Stock at the Conversion Rate in effect at the time of conversion. 
  

The Company shall notify Holders of any event triggering the right to convert the Securities as specified in the Indenture. 
  
 A Security in respect of which a Holder has delivered a Repurchase Notice or
Fundamental Change Repurchase Notice, as the case may be, exercising the option of such Holder to require the Company to purchase such Security, may be converted only if such Repurchase Notice or Fundamental Change Repurchase Notice, as the case may
be, is withdrawn in accordance with the terms of the Indenture. 
  
 The initial Conversion Rate is 23.7029 shares of Common Stock per $1,000 principal amount, subject to adjustment in certain events described in the Indenture. The Conversion Rate shall not be adjusted for any accrued and unpaid Interest,
accrued and unpaid Contingent Interest, if any or accrued and unpaid Additional Amounts, if any. Upon conversion, no payment shall be made by the Company with respect to accrued and unpaid Interest and accrued and unpaid Contingent Interest, if any;
provided that if a Conversion Date with respect to any Security occurs between an Interest Record Date for the payment of Interest (including Contingent Interest, if any) but prior to the corresponding Interest Payment Date, Interest,
Contingent Interest, if any, and Additional Amounts, if any, will be paid to the Holder of record of such Security on such Interest Record Date. Instead, such amount shall be deemed paid by the cash and shares of Common Stock, if any, delivered upon
conversion of any Security. A Holder shall receive, however, accrued and unpaid Additional Amounts, if any. In addition, no payment or adjustment shall be made in respect of dividends on the Common Stock, except as set forth in the Indenture.

  
 In addition, following certain corporate transactions as set
forth in Section 10.01(b) of the Indenture that occur prior to February 7, 2011 and that also constitute a Change of Control, a Holder who elects to convert its Securities in connection with such corporate transaction shall be entitled to receive
Additional Shares of Common Stock upon conversion. Notwithstanding the previous sentence, in the case of a Public Acquirer Change of Control, the Company may, in lieu of increasing the Conversion Rate by Additional Shares, elect to adjust the
Conversion Rate and Conversion Obligation such that from and after the effective date of such Public Acquirer Change of Control, Holders of the Securities shall be entitled to convert their Securities into a number of shares of Public Acquirer
Common Stock, as determined pursuant to Section 10.01(d) of the Indenture. 
  
 To surrender a Security for conversion, a Holder must (1) complete and manually sign the Conversion Notice attached hereto (or complete and manually sign a facsimile of such notice) and deliver such notice to the
Conversion Agent, (2) surrender the Security to the 
  

 A-8 

 Conversion Agent, (3) furnish appropriate endorsements and transfer documents, (4) if required by Section 10.02(g) of the
Indenture, pay Interest and Contingent Interest and (5) pay any transfer or similar tax, if required. 
  
 No fractional shares of Common Stock shall be issued upon conversion of any Security. Instead of any fractional share of Common Stock that would otherwise
be issued upon conversion of such Security, the Company shall pay a cash adjustment as provided in the Indenture. 
  
 In the event that the Company (i) is a party to a consolidation, merger, binding share exchange or combination, (ii) reclassifies the Common Stock, (iii)
sells or conveys all or substantially all of its property or assets to any Person, and as a result of any such event the Holders of Common Stock would be entitled to receive Exchange Property for their Common Stock, upon conversion of the Securities
after the effective date of such event, the Conversion Obligation and the Conversion Settlement Distribution shall be based on the applicable Conversion Rate and the Exchange Property, in each case in accordance with the Indenture. 
  
 9. Subordination 
  
 To the extent provided in the Indenture, the Securities are subordinated to Senior Indebtedness, as defined in the
Indenture, of the Company. To the extent provided in the Indenture, Senior Indebtedness must be paid before the Securities may be paid. The Company agrees, and each Securityholder by accepting a Security agrees, to the subordination provisions
contained in the Indenture and authorizes the Trustee to give it effect and appoints the Trustee as attorney-in-fact for such purpose. 
  
 10. Paying Agent, Conversion Agent and Registrar. 
  
 Initially, the Trustee shall act as Paying Agent, Conversion Agent and Registrar. The Company may appoint and change any Paying Agent, Conversion Agent or
Registrar without notice, other than notice to the Trustee. The Company or any of its Subsidiaries or any of their Affiliates may act as Paying Agent, Conversion Agent or Registrar. 
  
 11. Denominations; Transfer; Exchange. 
  
 The Securities are in fully registered form, without coupons, in denominations of $1,000 of principal amount and integral multiples of $1,000. A Holder
may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture. The Registrar need not transfer or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) for a period of 15 days before the mailing
of a notice of redemption of Securities to be redeemed or any Securities in respect of which a Repurchase Notice or Fundamental Change Repurchase Notice has been given and not withdrawn (except, in the case of a Security to be purchased in part, the
portion of the Security not to be purchased). 
  

 A-9 

 12. Persons Deemed Owners. 
  
 The registered Holder of this Security may be treated as the owner of this Security for all purposes. 
  
 13. Unclaimed Money or Securities. 
  
 The Trustee and the Paying Agent shall return to the Company upon written
request any money or securities held by them for the payment of any amount with respect to the Securities that remains unclaimed for two years, subject to applicable abandoned property law. After return to the Company, Holders entitled to the money
or securities must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person. 
  
 14. Amendment; Waiver. 
  
 Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended with the written consent of the Holders of at
least a majority in aggregate principal amount of the outstanding Securities and (ii) certain Events of Defaults may be waived with the written consent of the Holders of a majority in aggregate principal amount of the outstanding Securities. Subject
to certain exceptions set forth in the Indenture, without the consent of any Securityholder, the Company and the Trustee may amend the Indenture or the Securities (i) to add guarantees with respect to the Securities or secure the Securities, (ii) to
remove any guarantee added to the Securities pursuant to clause (i), unless such guarantee is required pursuant to Section 5.01(a) of the Indenture, (iii) to provide for the assumption by a successor Person of the Company’s obligations to the
Holders of Securities in the case of a merger, consolidation, conveyance, transfer, sale, lease or other disposition pursuant to Article 5 of the Indenture, (iv) to surrender any right or power conferred upon the Company in the Indenture, (v) to add
to the covenants or Events of Default of the Company for the benefit of the Holders of Securities, (vi) to cure any ambiguity or to correct or supplement any provision in the Indenture which may be inconsistent with any other provision in the
Indenture or which is otherwise defective; provided, however, that any such change or modification does not, in the good faith opinion of the Board of Directors of the Company (as evidenced by a Board Resolution) and the Trustee,
adversely affect the interests of the Holders of Securities in any material respect, (vii) to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the TIA, (viii) to establish the form of
Securities if issued in definitive form, (ix) to evidence and provide for the acceptance of the appointment under the Indenture of a successor Trustee, (x) to provide for uncertificated Securities in addition to or in place of Certificated
Securities; provided, however, that uncertificated Securities are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that uncertificated Securities are described in Section 163(f)(2)(B) of the
Code, (xi) to conform as necessary, the Indenture and this Security to the “Description of Notes” as set forth in the Offering Memorandum, (xii) to provide for conversion rights of Holders of Securities if any reclassification or change of
the Company’s Common Stock or any consolidation, merger, sale, lease or other disposition of all or substantially all of the Company’s assets occurs, (xiii) to change the Conversion Rate in accordance with the Indenture; provided,
however, that any increase in the Conversion Rate other than pursuant to Article 10 shall not adversely affect the 
  

 A-10 

 interests of the Holders of Securities (after taking into account U.S. federal income tax and other consequences of such
increase), (xiv) to make any changes or modifications necessary in connection with the registration of the Securities under the Securities Act as contemplated by the Registration Rights Agreement; provided, however, that any such change or
modification does not, in the good faith opinion of the Board of Directors of the Company (as evidenced by a Board Resolution) and the Trustee, adversely affect the interests of the Holders of Securities in any material respect and (xv) to add or
modify any other provisions of the Indenture with respect to matters or questions arising under the Indenture which the Company and the Trustee may deem necessary or desirable and which, in the good faith opinion of the Board of Directors of the
Company (as evidenced by a Board Resolution) and the Trustee, which change individually or in the aggregate with all other such changes, shall not adversely affect the interests of the Holders of Securities in any material respect. 
  
 15. Defaults and Remedies. 
  
 If any Event of Default with respect to Securities shall occur and be
continuing, the principal amount of the Securities and any accrued and unpaid Interest, accrued and unpaid Contingent Interest, if any, and accrued and unpaid Additional Amounts, if any, on all the Securities may be declared due and payable in the
manner and with the effect provided in the Indenture. 
  
 16. Trustee Dealings
with the Company. 
  
 Subject to certain limitations imposed
by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise
deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 
  
 17. Calculations in Respect of Securities. 
  
 The Company or its agents shall be responsible for making all calculations called for under the Securities including, but not limited to, determination of the market prices for the Securities and of the Common Stock
and the amounts of Interest, Contingent Interest and Additional Amounts, if any, accrued on the Securities. The Company shall make all calculations in good faith. Any calculations made in good faith and without manifest error shall be final and
binding on Holders of the Securities. The Company or its agents shall be required to deliver to the Trustee and the Conversion Agent a schedule of its calculations and each of the Trustee and the Conversion Agent shall be entitled to conclusively
rely upon the accuracy of such calculations without independent verification. The Trustee will forward such calculations to any Holder upon the request of such Holder.

 (i) as promptly as practicable (but in no event more than 90 days after the Closing Date) (the “Shelf Filing Deadline”), cause to be filed a registration statement pursuant to Rule 415 under the Securities Act or any
similar rule that may be adopted by the Commission (the “Shelf Registration Statement”), which Shelf Registration Statement shall provide for the registration and resales, on a continuous or delayed basis, of all Transfer Restricted
Securities held by Holders that have provided the information required pursuant to the terms of Section 2(b) hereof; 
  
 (ii) use its reasonable best efforts to cause the Shelf Registration Statement to be declared effective under the Securities Act by the
Commission not later than 180 days after the date hereof (the “Effectiveness Target Date”); and 
  

 4 

 (iii) use its reasonable best efforts to keep the Shelf Registration Statement
continuously effective, supplemented and amended as required by the Securities Act and by the provisions of Section 4(b) hereof to the extent necessary to ensure that (A) it is available for resales by the Holders of Transfer Restricted Securities
entitled, subject to Section 2(b), to the benefit of this Agreement and (B) conforms with the requirements of this Agreement and the Securities Act and the rules and regulations of the Commission promulgated thereunder as announced from time to
time, for a period (the “Effectiveness Period”) from the date the Shelf Registration Statement is declared effective by the Commission until the earliest of: 
  
 (1) the expiration of the holding period applicable to the Transfer Restricted Securities held by
non-affiliates of the Company under Rule 144(k) under the Securities Act; or 
  
 (2) the date when all of the Transfer Restricted Securities have been sold either pursuant to the Shelf Registration Statement or pursuant to Rule 144 under the Securities Act or any similar provision then in force,
or otherwise cease to be outstanding (whether as a result of redemption, repurchase, cancellation, conversion (in the case of a Note only) or otherwise). 
  
 The Company shall be deemed not have used its reasonable best efforts to keep the Shelf Registration Statement effective during the Effectiveness Period
if it voluntarily takes any action that would result in Holders of Transfer Restricted Securities not being able to offer and sell such Securities at any time during the Effectiveness Period, unless such action is (x) required by applicable law or
otherwise undertaken by the Company in good faith and for valid business reasons (not including avoidance of the Company’s obligations hereunder), including the acquisition or divestiture of assets, and (y) permitted by Section 4(b)(ii) hereof.

  
 (b) At the time the Shelf Registration
Statement is declared effective, each Holder that became a Notice Holder on or prior to the date fifteen (15) Business Days prior to such time of effectiveness shall be named as a selling securityholder in the Shelf Registration Statement and the
related Prospectus in such a manner as to permit such Holder to deliver such Prospectus to purchasers of Transfer Restricted Securities in accordance with applicable law, and each such Holder shall be required to 
  

 5 

 deliver a Prospectus to purchasers in accordance with the Securities Act. None of the Company’s
securityholders (other than the Holders of Transfer Restricted Securities) shall have the right to include any of the Company’s securities in the Shelf Registration Statement. 
  
 (c) If the Shelf Registration Statement or any Subsequent Shelf Registration Statement (as defined below)
ceases to be effective for any reason at any time during the Effectiveness Period (other than because all Transfer Restricted Securities registered thereunder shall have been resold pursuant thereto or shall have otherwise ceased to be Transfer
Restricted Securities), the Company shall use its reasonable best efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof or file an additional Shelf Registration Statement covering all of the securities that as of
the date of such filing are Transfer Restricted Securities ( a “Subsequent Shelf Registration Statement”). If a Subsequent Shelf Registration Statement is filed, the Company shall use its reasonable best efforts to cause the
Subsequent Shelf Registration Statement to become effective as promptly as is practicable after such filing and to keep such Registration Statement (or Subsequent Shelf Registration Statement) continuously effective until the end of the
Effectiveness Period. 
  
 (d) The Company shall
supplement and amend the 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. 

 
 (e) The Company shall cause the Shelf Registration
Statement and the related Prospectus and any amendment or supplement thereto, as of the effective date of the Shelf Registration Statement or such amendment or supplement, (i) to comply in all material respects with the applicable requirements of
the Securities Act, and (ii) not to contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein (in the case of the Prospectus, in light of the
circumstances under which they were made) not misleading. 
  
 (f) Each Holder agrees that if such Holder wishes to sell Transfer Restricted Securities pursuant to a Shelf Registration Statement and related Prospectus, it will do so only in accordance with this Section 2(f) and
Section 4(b). Each Holder wishing to sell Transfer Restricted Securities pursuant to a Shelf Registration Statement and related Prospectus agrees to deliver a Notice and Questionnaire to the Company at least fifteen (15) Business Days prior to any
intended distribution of Transfer Restricted Securities under the Shelf Registration Statement. From and after the date the Shelf Registration Statement is declared 
  

 6 

 effective the Company shall, as promptly as practicable after the date a Notice and Questionnaire is
delivered, and in any event upon the later of (x) fifteen (15) Business Days after such date (but no earlier than fifteen (15) Business Days after effectiveness) or (y) fifteen (15) Business Days after the expiration of any Suspension Period in
effect when the Notice and Questionnaire is delivered or put into effect within fifteen (15) Business Days of such delivery date: 
  
 (i) if required by applicable law, file with the SEC a post-effective amendment to the Shelf Registration Statement or prepare and, if
required by applicable law, file a supplement to the related Prospectus or a supplement or amendment to any document incorporated therein by reference or file any other required document so that the Holder delivering such Notice and Questionnaire is
named as a selling securityholder in the Shelf Registration Statement and the related Prospectus in such a manner as to permit such Holder to deliver such Prospectus to purchasers of the Transfer Restricted Securities in accordance with applicable
law and, if the Company shall file a post-effective amendment to the Shelf Registration Statement, use its reasonable best effort to cause such post-effective amendment to be declared effective under the Securities Act as promptly as is practicable,
but in any event by the date (the “Amendment Effectiveness Deadline Date”) that is sixty (60) days after the date such post effective amendment is required by this clause to be filed; 
  
 (ii) provide such Holder copies of the any documents filed
pursuant to Section 2(f)(i); and 
  
 (iii) notify
such Holder as promptly as practicable after the effectiveness under the Securities Act of any post-effective amendment filed pursuant to Section 2(f)(i); 
  
 provided that if such Notice and Questionnaire is delivered during a Suspension Period, the Company shall so inform the Holder delivering such Notice and
Questionnaire and shall take the actions set forth in clauses (i), (ii) and (iii) above upon expiration of the Suspension Period in accordance with Section 4(b). Notwithstanding anything contained herein to the contrary, (i) the Company shall be
under no obligation to name any Holder that is not a Notice Holder as a selling securityholder in any Registration Statement or related Prospectus; (ii) the Amendment Effectiveness Deadline Date shall be extended by up to fifteen (15) Business Days
from the Expiration of a Suspension Period (and the Company shall incur no obligation to pay Additional Amounts during such extension) if such Suspension Period shall be in effect on the Amendment Effectiveness Deadline Date; and (iii) the Company
shall not be obligated to file more than one post-effective amendment to the Shelf Registration Statement for all Holders during one three-month period. 
  

 7 

 3. Additional Amounts. 
  
 (a) If: 
  
 (i) the Shelf Registration Statement is not filed with the Commission prior to or on the Shelf Filing Deadline; 
  
 (ii) the Shelf Registration Statement has not been declared
effective by the Commission prior to or on the Effectiveness Target Date; 
  
 (iii) the Company has failed, through its omission, to perform its obligations set forth in Section 2(f) within the time period required therein; 
  
 (iv) any post-effective amendment to a Shelf Registration filed pursuant to Section 2(f)(i) has not become
effective under the Securities Act on or prior to the Amendment Effectiveness Deadline Date; 
  
 (v) except as provided in Section 4(b)(ii) hereof, the Shelf Registration Statement is filed and declared effective but, during the
Effectiveness Period, shall thereafter cease to be effective or fail to be usable for its intended purpose without being succeeded within ten (10) Business Days by a post-effective amendment to the Shelf Registration Statement, a supplement to the
Prospectus or a report filed with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act that cures such failure and, in the case of a post-effective amendment, is itself immediately declared effective; or 
  
 (vi) Suspension Periods exceed an aggregate of 60 days
within any 90-day period or an aggregate of 90 days in any 360 day period; 
  
 (each such event referred to in foregoing clauses (i) through (iv), a “Registration Default”), the Company hereby agrees to pay interest (“Additional Amounts”) with respect to
the Transfer Restricted Securities from and including the day following the Registration Default to but excluding the earlier of (1) the day on which the Registration Default has been cured and (2) the date the Shelf Registration Statement is no
longer required to be kept effective, accruing at a rate: 
  

 8 

 (A) in respect of the Notes, to each holder of Notes, (x) with respect to the first
90-day period during which a Registration Default shall have occurred and be continuing, equal to 0.25% per annum of the aggregate principal amount of the Notes, and (y) with respect to the period commencing on the 91st day following the day the Registration Default shall have occurred and be continuing, equal to 0.50% per annum of the
aggregate principal amount of the Notes; provided that in no event shall Additional Amounts accrue at a rate per year exceeding 0.50% of the aggregate principal amount of the Notes; and 
  
 (B) in respect of the Notes that are Transfer Restricted
Securities submitted for conversion into Common Stock during the existence of a Registration Default with respect to the Common Stock, the holder will not be entitled to receive any Additional Amounts with respect to such Common Stock; and

  
 (C) in respect of the Notes that are
Transfer Restricted Securities submitted for conversion into Common Stock during the existence of a Registration Default with respect to the Notes, the holder will receive from the Company on the settlement date with respect to such conversion,
accrued and unpaid Additional Amounts to the holders of such Notes calculated in accordance with paragraph (A) to the Conversion Date (as defined in the Indenture) relating to such settlement date; and 
  
 (D) in respect of the Notes or the Common Stock issued upon
conversion of the Notes, the holder will not be entitled to receive any Additional Amounts with respect to such Notes or Common Stock, as applicable, if a Registration Default with respect to the Common Stock issuable upon conversion of the Notes
occurs. 
  
 (b) All Additional Amounts accrued in
accordance with paragraph (A) above shall be paid in arrears to Record Holders by the Company on each Additional Amounts Payment Date. All Additional Amounts payable in accordance with paragraph (C) above shall be paid and delivered on the
settlement date with respect to such conversion. Upon the cure of all Registration Defaults relating to any particular Note or share of Common Stock, the accrual of Additional Amounts with respect to such Note or share of Common Stock will cease.

  

 9 

 All obligations of the Company set forth in this Section 3 that are outstanding with respect to any
Transfer Restricted Security at the time such security ceases to be a Transfer Restricted Security shall survive until such time as all such obligations with respect to such Transfer Restricted Security shall have been satisfied in full. 

 
 The Additional Amounts set forth above shall be the exclusive monetary
remedy available to the Holders of Transfer Restricted Securities for each Registration Default. 
  
 4. Registration Procedures. 
  
 (a) In connection with the Shelf Registration Statement, the Company shall comply with all the provisions of Section 4(b) hereof and shall
use its reasonable best efforts to effect such registration to permit the sale of the Transfer Restricted Securities, and pursuant thereto, shall as expeditiously as possible prepare and file with the Commission a Shelf Registration Statement
relating to the registration on any appropriate form under the Securities Act. 
  
 (b) In connection with the Shelf Registration Statement and any Prospectus required by this Agreement to permit the sale or resale of
Transfer Restricted Securities, the Company shall: 
  
 (i) Subject to any notice by the Company in accordance with this Section 4(b) of the existence of any fact or event of the kind described in Section 4(b)(iv)(D), use its reasonable best efforts to keep the Shelf Registration Statement
continuously effective during the Effectiveness Period; upon the occurrence of any event that would cause the Shelf Registration Statement or the Prospectus contained therein (A) to contain a material misstatement or omission or (B) not to be
effective and usable for resale of Transfer Restricted Securities during the Effectiveness Period, the Company shall file promptly an appropriate amendment to the Shelf Registration Statement, a supplement to the Prospectus or a report filed with
the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act, in the case of clause (A), correcting any such misstatement or omission, and, in the case of either clause (A) or (B), use its reasonable best efforts to cause such
amendment to be declared effective and the Shelf Registration Statement and the related Prospectus to become usable for their intended purposes as soon as practicable thereafter. 
  
 (ii) Notwithstanding Section 4(b)(i) hereof, the Company may suspend the effectiveness of the Shelf
Registration Statement (each such period, a “Suspension Period”): 
  

 10 

 (x) if an event occurs and is continuing as a result of which the Shelf Registration
Statement, the Prospectus, any amendment or supplement thereto, or any document incorporated by reference therein would, in the Company’s judgment, contain an untrue statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading; and 
  
 (y) if the Company determines in good faith that the disclosure of a material event at such time would be seriously detrimental to the
Company and its subsidiaries. 
  
 Upon the occurrence of any
event described in clauses (x) and (y) of this Section 4(b)(ii), the Company shall give notice to the Holders that the availability of the Shelf Registration is suspended and, upon actual receipt of any such notice, each Holder agrees not to sell
any Transfer Restricted Securities pursuant to the Shelf Registration until such Holder’s receipt of copies of the supplemented or amended Prospectus provided for in Section 4(b) hereof, and agrees to keep notice of such Suspension Period in
confidence. The Suspension Period shall not exceed 60 days in any ninety-day period, provided, that Suspension Periods shall not exceed an aggregate of 90 days in any 360-day period. The Company shall not be required to specify in the written
notice to the Holders the nature of the event giving rise to the Suspension Period. 
  
 (iii) Prepare and file with the Commission such amendments and post-effective amendments to the Shelf Registration Statement as may be
necessary to keep the Shelf Registration Statement effective during the Effectiveness Period; cause the Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities
Act, and to comply fully with the applicable provisions of Rules 424 under the Securities Act in a timely manner; and comply with the provisions of the Securities Act with respect to the disposition of all Notes or shares of Common Stock covered by
the Shelf Registration Statement during the applicable period in accordance with the intended method or methods of distribution by the sellers thereof set forth in the Shelf Registration Statement or supplement to the Prospectus. 
  
 (iv) Advise the selling Holders and any Initial Purchaser
that has provided in writing to the Company a telephone or facsimile number and address for notices, promptly and, if requested by such selling Holders, to confirm such advice in writing (which notice pursuant to clauses (B) through (D) below shall
be accompanied by an instruction to suspend the use of the Prospectus until the Company shall have remedied the basis for such suspension): 
  
 (A) when the Prospectus or any Prospectus supplement or post-effective amendment has been filed, and, with respect to the Shelf
Registration Statement or any post-effective amendment thereto, when the same has become effective, 
  

 11 

 (B) of any request by the Commission for amendments to the Shelf Registration Statement
or amendments or supplements to the Prospectus or for additional information relating thereto, 
  
 (C) of the issuance by the Commission of any stop order suspending the effectiveness of the Shelf Registration Statement under the
Securities Act or of the suspension by any state securities commission of the qualification of the Transfer Restricted Securities for offering or sale in any jurisdiction, or the threatening or initiation of any proceeding for any of the preceding
purposes, or 
  
 (D) of the existence of any
fact or the happening of any event, during the Effectiveness Period, that makes any statement of a material fact made in the Shelf Registration Statement, the Prospectus, any amendment or supplement thereto, or any document incorporated by reference
therein untrue, or that requires the making of any additions to or changes in the Shelf Registration Statement or the Prospectus in order to make the statements therein (in the case of the Prospectus, in the light of the circumstances under which
they were made) not misleading. 
  
 If at any time the Commission
shall issue any stop order suspending the effectiveness of the Shelf Registration Statement, or any state securities commission or other regulatory authority shall issue an order suspending the qualification or exemption from qualification of the
Transfer Restricted Securities under state securities or Blue Sky laws, the Company shall use its reasonable best efforts to obtain the withdrawal or lifting of such order at the earliest possible time and will provide to each Holder who is named in
the Shelf Registration Statement prompt notice of the withdrawal of any such order. 
  
 (v) Make available at reasonable times for inspection by one or more representatives of the selling Holders, designated in writing by a
Majority of Holders whose Transfer Restricted 
  

 12 

 Securities are included in the Shelf Registration Statement, and any attorney or accountant retained by
such selling Holders and any Initial Purchaser participating in any disposition pursuant to the Shelf Registration Statement, all financial and other records, pertinent corporate documents and properties of the Company as shall be reasonably
necessary to enable them to conduct a reasonable investigation within the meaning of Section 11 of the Securities Act, and cause the Company’s officers, directors, managers and employees to supply all information reasonably requested by any
such representative or representatives of the selling Holders, attorney or accountant in connection therewith, provided that (x) appropriate safeguards are in place to protect the confidentiality of such information and (y) in no event shall
the Company be required to disclose any proprietary information to any competitor or agent thereof. 
  
 (vi) If requested by any selling Holders or the Representative, promptly incorporate in the Shelf Registration Statement or Prospectus,
pursuant to a supplement or post-effective amendment if necessary, such information as such selling Holders may reasonably request to have included therein, including, without limitation, information relating to the “Plan of
Distribution” of the Transfer Restricted Securities. 
  
 (vii) Deliver to each selling Holder, without charge, as many copies of the Prospectus (including each preliminary Prospectus) and any amendment or supplement thereto as such Persons reasonably may request; subject to
any notice by the Company in accordance with this Section 4(b) of the existence of any fact or event of the kind described in Section 4(b)(iv)(D), the Company hereby consents to the use of the Prospectus and any amendment or supplement thereto by
each of the selling Holders in connection with the offering and the sale of the Transfer Restricted Securities covered by the Prospectus or any amendment or supplement thereto. 
  
 (viii) Before any public offering of Transfer Restricted Securities, cooperate with the selling Holders and
their counsel in connection with the registration and qualification of the Transfer Restricted Securities under the securities or Blue Sky laws of such jurisdictions in the United States as the selling Holders may reasonably request and do any and
all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Transfer Restricted Securities covered by the Shelf Registration Statement; provided, however, that the Company shall not be required (A)
to register or qualify as a 
  

 13 

 foreign corporation or a dealer of securities where it is not now so qualified or to take any action that
would subject it to the service of process in any jurisdiction where it is not now so subject, other than service of process for suits arising out of the Initial Placement or any offering pursuant to the Shelf Registration Statement, or (B) to
subject itself to general or unlimited service of process or to taxation in any such jurisdiction if they are not now so subject. 
  
 (ix) Unless any Transfer Restricted Securities shall be in book-entry form only, cooperate with the selling Holders to facilitate the
timely preparation and delivery of certificates representing Transfer Restricted Securities to be sold and not bearing any restrictive legends (unless required by applicable securities laws); and enable such Transfer Restricted Securities to be in
such denominations and registered in such names as the Holders may request at least two Business Days before any sale of Transfer Restricted Securities. 
  
 (x) Use its reasonable best efforts to cause the Transfer Restricted Securities covered by the Shelf Registration Statement to be
registered with or approved by such other U.S. governmental agencies or authorities as may be necessary to enable the seller or sellers thereof to consummate the disposition of such Transfer Restricted Securities. 
  
 (xi) Subject to Section 4(b)(ii) hereof, if any fact or
event contemplated by Section 4(b)(iv)(B) through (D) hereof shall exist or have occurred, use its reasonable best efforts to prepare a supplement or post-effective amendment to the Shelf Registration Statement or related Prospectus or any document
incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of Transfer Restricted Securities, the Prospectus will not contain an 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, in light of the circumstances in which they are made, not misleading. 
  

(xii) Provide CUSIP numbers for all Transfer Restricted Securities not later than the effective date of the Shelf Registration
Statement and provide the Trustee under the Indenture with certificates for the Notes that are in a form eligible for deposit with The Depository Trust Company. 
  
 (xiii) Cooperate and assist in any filings required to be made with the NASD and, subject to the proviso in
Section 4(b)(v), in the performance of any due diligence investigation by any underwriter that is required to be undertaken in accordance with the rules and regulations of the NASD. 
  

 14 

 (xiv) Otherwise use its reasonable best efforts to comply with all applicable rules and
regulations of the Commission and all reporting requirements under the rules and regulations of the Exchange Act. 
  
 (xv) Make generally available to its security holders an earnings statement satisfying the provisions of Section 11(a) of the Securities
Act as soon as practicable after the effective date of the Shelf Registration Statement and in any event no later than 45 days after the end of a 12-month period (or 90 days, if such period is a fiscal year) beginning with the first month of the
Company’s first fiscal quarter commencing after the effective date of the Shelf Registration Statement. 
  
 (xvi) Cause the Indenture to be qualified under the TIA not later than the effective date of the Shelf Registration Statement required by
this Agreement, and, in connection therewith, cooperate with the Trustee and the holders of Notes to effect such changes to the Indenture as may be required for such 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 thereunder to execute all documents that may be required to effect such changes and all other forms and documents required to be filed with the Commission to enable such Indenture to be so
qualified in a timely manner. In the event that any such amendment or modification referred to in this Section 4(b)(xvi) involves the appointment of a new trustee under the Indenture, the Company shall appoint a new trustee thereunder pursuant to
the applicable provisions of the Indenture. 
  
 (xvii) Cause all Common Stock covered by the Shelf Registration Statement to be listed or quoted, as the case may be, on each securities exchange or automated quotation system on which Common Stock is then listed or quoted. 
  
 (xviii) Provide to each Holder upon written request each
document filed with the Commission pursuant to the requirements of Section 13 and Section 15 of the Exchange Act after the effective date of the Shelf Registration Statement, unless such document is available through the Commission’s EDGAR
system. 
  
 (xix) In connection with any
underwritten offering conducted pursuant to Section 8 hereof, make such representations and 
  

 15 

 warranties to the underwriters, in form, substance and scope as are customarily made by issuers to
underwriters in primary underwritten offerings and covering matters including, but not limited to, those set forth in the Purchase Agreement. 
  
 (xx) In connection with any underwritten offering conducted pursuant to Section 8 hereof, obtain opinions of counsel to the Company and
updates thereof (which counsel and opinions (in form, scope and substance) shall be reasonably satisfactory to the Managing Underwriters) addressed to each selling Holder and the underwriters, if any, covering such matters as are customarily covered
in opinions requested in underwritten offerings and such other matters as may be reasonably requested by such Holders and underwriters. 
  
 (xxi) In connection with any underwritten offering conducted pursuant to Section 8, hereof, obtain “comfort” letters and updates
thereof from the independent certified public accountants of the Company (and, if necessary, any other independent certified public accountants of any subsidiary of the Company or of any business acquired by the Company for which financial
statements and financial data are, or are required to be, included in the Shelf Registration Statement), addressed to each selling Holder of Securities registered thereunder and the underwriters, in customary form and covering matters of the type
customarily covered in “comfort” letters in connection with primary underwritten offerings. 
  
 (xxii) In connection with any underwritten offering conducted pursuant to Section 8 hereof, deliver such documents and certificates as may
be reasonably requested by the Majority of Holders and the Managing Underwriters, including those to evidence compliance with any customary conditions contained in the Purchase Agreement or other agreement entered into by the Company. 
  
 (xxiii) In connection with underwritten offering conducted
pursuant to Section 8 hereof, the Company shall, if requested, promptly include or incorporate in a Prospectus supplement or post-effective amendment to the Shelf Registration Statement such information as the Managing Underwriters reasonably agree
should be included therein and to which the Company does not reasonably object and shall make all required filings of such Prospectus supplement or post-effective amendment as soon as practicable after it is notified of the matters to be included or
incorporated in such Prospectus supplement or post-effective amendment. 
  

 16 

 (xxiv) Use its best efforts to take all other steps necessary to effect the registration
of the Notes covered by the Shelf Registration Statement. 
  
 (xxv) Enter into customary agreements (including, if requested, an underwriting agreement in customary form) and take all other appropriate actions in order to expedite or facilitate the registration or the
disposition of the Notes, and in connection therewith, if an underwriting agreement is entered into, cause the same to contain indemnification provisions and procedures no less favorable than those set forth in Section 6 hereof. 
  
 The actions set forth in clauses (xx), (xxi), (xxii) and (xxiii) of this
Section 4(b) shall be performed at (A) the effectiveness of the Shelf Registration Statement and each post-effective amendment thereto; and (b) each closing under any underwriting or similar agreement as and to the extent required thereunder.

  
 (c) Each Holder agrees by acquisition of a
Transfer Restricted Security that, upon receipt of any notice (a “Suspension Notice”) from the Company of the existence of any fact of the kind described in Section 4(b)(iv)(D) hereof, such Holder will forthwith
discontinue disposition of Transfer Restricted Securities pursuant to the Shelf Registration Statement until: 
  
 (i) such Holder has received copies of the supplemented or amended Prospectus contemplated by Section 4(b)(xi) hereof; or 
  
 (ii) such Holder is advised in writing by the Company that
the use of the Prospectus may be resumed, and has received copies of any additional or supplemental filings that are incorporated by reference in the Prospectus. 
  
 If so directed by the Company, each Holder will deliver to the Company (at the Company’s expense) all copies, other than permanent file
copies then in such Holder’s possession, of the Prospectus covering such Transfer Restricted Securities that was current at the time of receipt of such notice of suspension. 
  
 (d) Each Holder agrees by acquisition of a Transfer Restricted Security, that no Holder shall be entitled to
sell any of such Transfer Restricted Securities pursuant to a 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(f)
hereof (including the information required to be included in such Notice and Questionnaire) and the information set forth in the next sentence. The 
  

 17 

 Company may require each Notice Holder of Notes to be sold pursuant to the Shelf Registration Statement
to furnish to the Company such information regarding the Holder and the distribution of such Notes as the Company may from time to time reasonably require for inclusion in such Registration Statement. 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
Transfer Restricted Securities as the Company may from time to time reasonably request in writing. Any sale of any Transfer Restricted Securities by any Holder shall constitute a representation and warranty by such Holder that the information
relating to such Holder and its plan of distribution is as set forth in the Prospectus delivered by such Holder in connection with such disposition, that such Prospectus does not as of the time of such sale contain any untrue statement of a material
fact relating to or provided by such Holder or its plan of distribution and that such Prospectus does not as of the time of such sale omit to state any material fact relating to or provided by such Holder or its plan of distribution necessary to
make the statements in such Prospectus, in the light of the circumstances under which they were made not misleading. The Company may exclude from such Shelf Registration Statement the Notes of any Holder that unreasonably fails to furnish such
information within a reasonable time after receiving such request. 
  
 5. Registration Expenses. 
  
 All expenses
incident to the Company’s performance of or compliance with this Agreement shall be borne by the Company regardless of whether a Shelf Registration Statement becomes effective, including, without limitation: 
  
 (a) all registration and filing fees and expenses (including
filings made with the NASD); 
  
 (b) all fees and
expenses of compliance with federal securities and state Blue Sky or securities laws; 
  
 (c) all expenses of printing (including printing of Prospectuses and certificates for the Common Stock to be issued upon conversion of the
Notes) and the Company’s expenses for messenger and delivery services and telephone; 
  
 (d) all fees and disbursements of counsel to the Company; 
  
 (e) all application and filing fees in connection with listing (or authorizing for quotation) the Common
Stock on a national securities exchange or automated quotation system pursuant to the requirements hereof; and 
  

 18 

 (f) all fees and disbursements of independent certified public accountants of the
Company. 
  
 The Company shall bear its internal expenses
(including, without limitation, all salaries and expenses of their officers and employees performing legal, accounting or other duties), the expenses of any annual audit and the fees and expenses of any Person, including special experts, retained by
the Company. The Company shall pay all expenses customarily borne by issuers in an underwritten offering as set forth in Section 8(c) hereof. 
  
 6. Indemnification And Contribution.  
  
 (a) The Company agrees to indemnify and hold harmless each Holder of Transfer Restricted Securities (including each Initial Purchaser),
its directors, officers, and employees, Affiliates and agents and each person, if any, who controls any such Holder within the meaning of the Securities Act or the Exchange Act (each, an “Indemnified Holder”), against
any loss, claim, damage, liability or expense, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to resales of the Transfer Restricted Securities), to which such
Indemnified Holder may become subject, insofar as any such loss, claim, damage, liability or action arises out of, or is based upon: 
  
 (i) any untrue statement or alleged untrue statement of a material fact contained in (A) the Shelf Registration Statement as originally
filed or in any amendment thereof, in any Prospectus, or in any amendment or supplement thereto, or (B) any blue sky application or other document or any amendment or supplement thereto prepared or executed by the Company (or based upon written
information furnished by or on behalf of the Company expressly for use in such blue sky application or other document or amendment or supplement) filed in any jurisdiction specifically for the purpose of qualifying any or all of the Transfer
Restricted Securities under the securities law of any state or other jurisdiction (such application or document being hereinafter called a “Blue Sky Application”); or 
  
 (ii) the omission or alleged omission to state therein any
material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, 
  

 19 

 and agrees to reimburse each Indemnified Holder promptly upon demand for any legal or other expenses reasonably incurred
by such Indemnified Holder in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that: (i) the Company shall not be liable in any such case
to the extent that any such loss, claim, damage, liability or expense arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information
furnished to the Company by or on behalf of such Holder (or its related Indemnified Holder) specifically for use therein, and (ii) the indemnification contained in this Section 6(a) shall not inure to the benefit of any Holder (or to the benefit of
any person controlling such Holder) on account of any such losses, claims, damages or liabilities caused by any untrue statement or alleged untrue statement or omission or alleged omission made in any preliminary prospectus if either (A)(x) such
Holder failed to send or deliver a copy of the Prospectus with or prior to the delivery of written confirmation of the sale by such Holder to the person asserting the claim from which such losses, claims damages or liabilities arise and (y) the
Prospectus would have corrected such untrue statement or alleged untrue statement or such omission or alleged omission and would be a complete defense to such claim, or (B)(x) such untrue statement or alleged untrue statement, omission or alleged
omission is corrected in an amendment or supplement to the Prospectus and (y) having previously been furnished by or on behalf of the Company with copies of the Prospectus as so amended or supplemented, such Holder thereafter fails to deliver such
Prospectus as so amended or supplemented, with or prior to the delivery of written confirmation of the sale of a Transfer Restricted Security to the person asserting the claim from which such losses, claims, damages or liabilities arise and such
Prospectus, as so amended or supplemented would be a complete defense to such claim. The foregoing indemnity agreement is in addition to any liability which the Company may otherwise have. 
  
 The Company also agrees to indemnify as provided in this Section 6(a) or
contribute as provided in Section 6(e) hereof to Losses (as defined below) of each underwriter, if any, of Notes registered under a Shelf Registration Statement, their directors, officers, employees, Affiliates or agents and each person who controls
such underwriter on substantially the same basis as that of the indemnification of the Initial Purchasers and the selling Holders provided in this Section 6(a) and shall, if requested by any Holder, enter into an underwriting agreement reflecting
such agreement, as provided in Section 4(b)(xxv) hereof. 
  
 (b) Each Holder, severally and not jointly, agrees to indemnify and hold harmless the Company, its directors, officers and employees and each person, if any, who controls the Company within the meaning of the
Securities Act or the Exchange Act to the same extent as the foregoing indemnity from the Company to each such Holder, but only with reference to written information relating to such Holder furnished to the Company 
  

 20 

 by or on behalf of such Holder specifically for inclusion in the documents referred to in the foregoing
indemnity. This indemnity agreement set forth in this Section shall be in addition to any liabilities which any such Holder may otherwise have. In no event shall any Holder, its directors, officers or any person who controls such Holder be liable or
responsible for any amount in excess of the amount by which the total amount received by such Holder with respect to its sale of Transfer Restricted Securities pursuant to a Shelf Registration Statement exceeds (i) the amount paid by such Holder for
such Transfer Restricted Securities and (ii) the amount of any damages that such Holder, its directors, officers or any person who controls such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. 
  
 (c) Promptly
after receipt by an indemnified party under this Section 6 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 6, notify
the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party (i) shall not relieve it from any liability which it may have under paragraphs (a) or (b)
of this Section unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses, and (ii) shall not, in any event, relieve it from any
liability which it may have to an indemnified party otherwise than under paragraphs (a) or (b) of this Section 6. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the
indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel satisfactory to the indemnified party. After
notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 6 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the Holders shall have the right to employ a single counsel to represent jointly the
Holders and their officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Holders against the Company under this Section 6 if the Holders seeking
indemnification shall have been advised by legal counsel that there may be one or more legal defenses available to such Holders and their respective officers, employees and controlling persons that are different from or additional to those available
to the Company, and in that event, the fees and expenses of such separate counsel shall be paid by the Company. 
  

 21 

 (d) The indemnifying party under this Section shall not be liable for any settlement of
any proceeding effected without its written consent, which shall not be withheld unreasonably, but if settled with such consent or if there is a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party
against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party
for fees and expenses of counsel as contemplated by Section 6(c) hereof, the 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
30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party
shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could
have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (x) includes an unconditional release of such indemnified party from all liability on claims that are
the subject matter of such action, suit or proceeding and (y) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. 
  
 (e) If the indemnification provided for in this Section 6
shall for any reason be unavailable or insufficient to hold harmless an indemnified party under Section 6(a) or 6(b) in respect of any loss, claim, damage or liability (or action in respect thereof) referred to therein, each indemnifying party
shall, in lieu of indemnifying such indemnified party, contribute to the aggregate amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability (including legal or other expenses reasonably incurred in
connection with investigating or defending any loss, claim, liability, damage or action) (collectively “Losses”) (or action in respect thereof): 
  
 (i) in such proportion as is appropriate to reflect the relative benefits received by the Company from the
offering and sale of the Transfer Restricted Securities on the one hand and a Holder with respect to the sale by such Holder of the Transfer Restricted Securities on the other, or 
  
 (ii) if the allocation provided by Section (6)(d)(i) is not permitted by applicable law, in such proportion
as is appropriate to reflect not only the relative benefits referred to in Section 6(d)(i) 
  

 22 

 but also the relative fault of the Company on the one hand and the Holders on the other in connection
with the statements or omissions or alleged statements or alleged omissions that resulted in such loss, claim, damage or liability (or action in respect thereof), as well as any other relevant equitable considerations. 
  
 The relative benefits received by the Company on the one hand and a Holder on the other with
respect to such offering and such sale shall be deemed to be in the same proportion as the total net proceeds from the offering of the Notes purchased under the Purchase Agreement (before deducting expenses) received by the Company, on the one hand,
bear to the total proceeds received by such Holder with respect to its sale of Transfer Restricted Securities on the other. The relative fault of the parties shall be determined by reference to whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Holders on the other, the intent of the parties and their relative knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and each Holder agree that it would not be just and equitable if the amount of contribution pursuant to this Section 6(e) were determined by pro rata allocation or by
any other method of allocation that does not take into account the equitable considerations referred to in the first sentence of this paragraph (e). 
  
 The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in
this Section 6 shall be deemed to include, for purposes of this Section 6, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending or preparing to defend any such action or claim.

  
 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’ obligations to contribute as provided in this Section 6(e) are several and
not joint. 
  
 (f) The provisions of this Section
6 shall remain in full force and effect, regardless of any investigation made by or on behalf of any Holder or the Company or any of the officers, directors or controlling persons referred to in Section 6 hereof, and will survive the sale by a
Holder of Transfer Restricted Securities. 
  
 7. Rule 144A and
Rule 144. The Company agrees with each Holder, for so long as any Transfer Restricted Securities remain outstanding and during any period in which the Company (i) is not subject to Section 13 or 15(d) of the Exchange Act, to make available, upon
request of any Holder, to such Holder or beneficial owner of Transfer Restricted Securities in connection with any sale thereof and any prospective purchaser of such Transfer Restricted Securities 
  

 23 

 designated by such Holder or beneficial owner, the information required by Rule 144A(d)(4) under the Securities Act in
order to permit resales of such Transfer Restricted Securities pursuant to Rule 144A, and (ii) is subject to Section 13 or 15 (d) of the Exchange Act, to use its reasonable best efforts to make all filings required thereby in a timely manner in
order to permit resales of such Transfer Restricted Securities pursuant to Rule 144. 
  
 8. Underwritten Registrations.  
  
 (a) Any Holder of Transfer Restricted Securities who desires to do so may sell Transfer Restricted Securities (in whole or in part) in an underwritten offering; provided that (i) the electing Holders of at least
33 1/3% in aggregate principal amount of the Transfer Restricted Securities then covered by the Shelf
Registration Statement shall request such an offering, (ii) at least such aggregate principal amount of such Transfer Restricted Securities shall be included in such offering; and provided further that the Company shall not be obligated to
participate in more than one underwritten offering during the Effectiveness Period and (iii) such Holder does not object to any other Holder including its Transfer Restricted Securities (in whole or in part) in such offering. Upon receipt of such a
request, the Company shall provide all Holders of Transfer Restricted Securities written notice of the request, which notice shall inform such Holders that they have the opportunity to participate in the offering. If any of the Transfer Restricted
Securities covered by the Shelf Registration Statement are to be sold in an underwritten offering, the Managing Underwriters shall be selected by the Majority of Holders. 
  
 (b) No person may participate in any underwritten offering pursuant to the Shelf Registration Statement
unless such person (i) agrees to sell such person’s Notes on the basis reasonably provided in any underwriting arrangements approved by the persons entitled hereunder to approve such arrangements; (ii) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements; and (iii) if such Holder is not then a Notice Holder, such Holder returns a completed and signed
Notice and Questionnaire to the Company in accordance with Section 2(f) hereof within a reasonable amount of time before such underwritten offering. 
  
 (c) The Holders participating in any underwritten offering shall be responsible for any underwriting discounts and commissions and fees
and, subject to Section 5 hereof, expenses of their own counsel. The Company shall pay all expenses customarily borne by issuers in an underwritten offering, including but not limited to filing fees, the fees and disbursements of its counsel and
independent public accountants and any printing expenses incurred in connection with such underwritten offering. 
  

 24 

 Notwithstanding the foregoing or the provisions of Section 4(b)(xxiii) hereof, upon receipt of a request
from the Managing Underwriter or a representative of holders of a majority of the Transfer Restricted Securities to be included in an underwritten offering to prepare and file an amendment or supplement to the Shelf Registration Statement and
Prospectus in connection with an underwritten offering, the Company may delay the filing of any such amendment or supplement for up to 90 days if the Board of Directors of the Company shall have determined in good faith that the Company has a bona
fide business reason for such delay. 
  
 9. Miscellaneous.

  
 (a) Remedies. The Company acknowledges
and agrees that any failure by the Company to comply with its obligations under Section 2 hereof may result in material irreparable injury to the Initial Purchasers or 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, in addition to being entitled to exercise all rights provided to it herein, in the Indenture or in the Purchase Agreement or granted by law,
including recovery of liquidated or other damages, the Initial Purchasers or any Holder may obtain such relief as may be required to specifically enforce the Company’s obligations under Section 2 hereof. The Company further agrees to waive the
defense in any action for specific performance that a remedy at law would be adequate. 
  
 (b) Actions Affecting Transfer Restricted Securities. The Company shall not, directly or indirectly, take any action with respect
to the Transfer Restricted Securities as a class that would adversely affect the ability of the Holders of Transfer Restricted Securities to include such Transfer Restricted Securities in a registration undertaken pursuant to this Agreement.

  
 (c) No Inconsistent Agreements. The
Company has not, as of the date hereof, entered into, nor shall it, on or after the date hereof, enter into, any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise
conflicts with the provisions hereof. In addition, the Company shall not grant to any of its securityholders (other than the Holders of Transfer Restricted Securities in such capacity) the right to include any of its securities in the Shelf
Registration Statement provided for in this Agreement other than the Transfer Restricted Securities. 
  
 (d) Amendments and Waivers. This Agreement may not be amended, modified or supplemented, and waivers or consents to or departures
from the provisions hereof may not be given, unless the Company has obtained the written consent of a Majority of Holders; 
  

 25 

 provided, however, that with respect to any matter that directly or indirectly adversely
affects the rights of any Initial Purchaser hereunder, the Company shall obtain the written consent of each such Initial Purchaser against which such amendment, qualification, supplement, waiver or consent is to be effective. Notwithstanding the
foregoing (except the foregoing proviso), a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders whose securities are being sold pursuant to a Shelf Registration Statement
and does not directly or indirectly adversely affect the rights of other Holders, may be given by the Majority of Holders, determined on the basis of Notes being sold rather than registered under such Shelf Registration Statement. 
  
 (e) Notices. All notices and other communications
provided for or permitted hereunder shall be made in writing by hand delivery, first class mail (registered or certified, return receipt requested), facsimile transmission, or air courier guaranteeing overnight delivery: 
  
 (i) if to a Holder, at the address set forth on the records
of the registrar under the Indenture or the transfer agent of the Common Stock, as the case may be; and 
  
 (ii) if to the Company, initially at its address set forth in the Purchase Agreement. 
  
 All such notices and communications shall be deemed to have been duly given:
at the time delivered by hand, if personally delivered; five Business Days after being deposited in the mail, postage prepaid, if mailed; when receipt acknowledged, if transmitted by facsimile; and on the next Business Day, if timely delivered to an
air courier guaranteeing overnight delivery. 
  
 Any party hereto
may change the address for receipt of communications by giving written notice to the others. 
  
 By its acceptance of the Notes, each Holder agrees to hold any communication by the Company in response to a notice of a proposed sale in confidence, including any notice of a Suspension Period or any delay effected
pursuant to Section 4(c). 
  
 (f) Successors
and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and assigns of each of the parties, including without limitation and without the need for an express assignment, subsequent Holders of Transfer
Restricted Securities. The Company hereby agrees to extend the benefit of this Agreement to any Holder and any such Holder may specifically enforce the provisions of this Agreement as if an original party hereto. 
  

 26 

 (g) 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 an original and all of which taken together shall constitute one and the same agreement. 
  
 (h) Notes Held by the Company or Its Affiliates.
Whenever the consent or approval of Holders of a specified percentage of Transfer Restricted Securities is required hereunder, Transfer Restricted Securities held by the Company or its Affiliates (other than subsequent Holders if such subsequent
Holders are deemed to be Affiliates solely by reason of their holding of such Notes) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage. 
  
 (i) Headings. The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the meaning hereof. 
  
 (j) Governing Law. This Agreement shall be governed by and construed in accordance with the law of the State of New York.

  
 (k) Severability. If any one or more
of the provisions contained herein, or the application thereof in any circumstance, is held invalid, illegal or unenforceable, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions
contained herein shall not be affected or impaired thereby, it being intended that all of the rights and privileges of the parties shall be enforceable to the fullest extent permitted by law. 
  
 (l) Entire Agreement. This Agreement is intended by
the parties as a final expression of their agreement and 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. 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 Transfer Restricted Securities. This Agreement supersedes all prior agreements
and understandings between the parties with respect to such subject matter.
