except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company, as described in Section 14.2. Such

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

  

 9 

 
purpose the Outstanding Securities shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such
record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date. 
  
 ARTICLE II 
  
 THE SECURITIES 
  
 Section 2.1. Form and Dating. 
  
 The Securities and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A attached hereto, which is a part of
this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule or usage (provided that any such notation, legend or endorsement required by usage is in a form acceptable to the Company). The Company
shall provide any such notations, legends or endorsements to the Trustee in writing. Each Security shall be dated the date of its authentication. 
  
 (a) Restricted Global Securities. All of the Securities are being offered and sold to QIBs in reliance on Rule 144A and shall be issued initially
in the form of one or more Restricted Global Securities, which shall be deposited with the Trustee at its Corporate Trust Office, as custodian for the Depositary and registered in the name of DTC or the nominee thereof, duly executed by the Company
and authenticated by the Trustee as hereinafter provided. The aggregate principal amount of the Restricted Global Securities may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary as
hereinafter provided. 
  
 (b) Global Securities in General.
Each Global Security shall represent such of the outstanding Securities as shall be specified therein and each shall provide that it shall initially represent the aggregate amount of outstanding Securities stated thereon, but that the aggregate
amount of outstanding Securities represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, redemptions, repurchases and conversions of such Securities. 
  
 Any adjustment of the aggregate principal amount of a Global Security to
reflect the amount of any increase or decrease in the amount of outstanding Securities represented thereby shall be made by the Trustee in accordance with instructions given by the Holder thereof as required by Section 2.12 and shall be made on the
records of the Trustee and the Depositary. 
  
 Neither any members
of, or participants in, the Depositary (collectively, the “Agent Members”) nor any other persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Security registered in the
name of the Depositary or any nominee thereof, or under any such Global Security, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner
and Holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing contained herein shall (A) prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any 

  

 10 

 
written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or (B) 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. 
  
 (c) Certificated Securities. Certificated Securities will be issued
only under the limited circumstances provided in Section 2.12(a)(i). 
  
 Section 2.2. Execution and Authentication. 
  
 The Securities shall be executed on behalf of the Company by any Officer. The signature of the Officer on the Securities may be manual or facsimile. 
  
 A Security bearing the manual or facsimile signature of an individual who was at the time of the execution of the Security an Officer shall bind the
Company, notwithstanding that such individual has ceased to hold such office(s) prior to the authentication and delivery of such Securities or did not hold such office(s) at the date of authentication of such Securities. 
  
 No Security shall be entitled to any benefit under this Indenture or be valid
or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein duly executed by the Trustee by manual signature of an authorized signatory, and such certificate upon
any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. 
  
 The Trustee shall authenticate and deliver the Securities for original issue in an aggregate principal amount of up to $600,000,000 (which amount includes
Securities issued upon exercise of the Initial Purchaser’s option provided for in the Purchase Agreement) upon one or more Company Orders without any further action by the Company (other than as contemplated in Section 14.4 and Section 14.5).
Subject to the preceding sentence, at any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities executed by the Company to the Trustee for authentication. Except as otherwise provided in
this Article Two, the Trustee shall thereupon authenticate and make available for delivery said Securities to or upon Company Order. The aggregate principal amount of the Securities due at the Stated Maturity thereof outstanding at any time may not
exceed the amount set forth in this paragraph except as provided in Section 2.7. In authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall receive and
shall be fully protected in relying upon: 
  
 (a) a copy of the
Board Resolution in or pursuant to which the terms and form of the Securities were established, the issuance and sale of the Securities was authorized, this Indenture was authorized and specified Officers were authorized to establish the form and
determine the terms of the Securities and the form of this Indenture, to execute the Securities and this Indenture on behalf of the Company and to take any other necessary actions relating thereto and evidence of any actions taken by authorized
Officers pursuant to that Board Resolution, each certified by the Secretary or an Assistant Secretary of the Company to have been duly adopted by 

  

 11 

 
the Board of Directors or taken by any authorized Officer and to be in full force and effect as of the date of such certificate; 
  
 (b) an Officers’ Certificate delivered in accordance with Sections 14.4
and 14.5; and 
  
 (c) an Opinion of Counsel reasonably
satisfactory to the Trustee. 
  
 The Trustee shall act as the
initial authenticating agent. Thereafter, the Trustee may appoint an authenticating agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in
this Indenture to authentication by the Trustee includes authentication by such agent. 
  
 The Securities shall be issued only in registered form without coupons and only in denominations of $1,000 of principal amount and any multiple of $1,000. 
  
 Section 2.3. Registrar, Paying Agent, Conversion Agent and Bid Solicitation Agent. 
  
 The Company shall maintain an office or agency where Securities may be
presented for registration of transfer or for exchange (“Registrar”), an office or agency where Securities may be presented for redemption, repurchase or payment (“Paying Agent”), an office or agency
where Securities may be presented for conversion (“Conversion Agent”) and an office or agency where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Company shall also
appoint a bid solicitation agent (“Bid Solicitation Agent”) to act as set forth in Section 3 of the Securities. Pursuant to Section 6.5, the Company will at all times maintain a Registrar, Paying Agent, Conversion Agent, and Bid
Solicitation Agent and an office or agency where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served in the Borough of Manhattan, New York City. The Registrar shall keep a register of the
Securities and of their transfer and exchange. 
  
 The Company may
have one or more co-registrars, one or more additional paying agents, one or more additional conversion agents and one or more additional Bid Solicitation Agents. The term Paying Agent includes any additional paying agent, including any named
pursuant to Section 6.5. The term Conversion Agent includes any additional conversion agent, including any named pursuant to Section 6.5. 
  
 The Company shall enter into an appropriate limited agency agreement with any Registrar, Paying Agent, Conversion Agent, Bid Solicitation Agent or
co-registrar (in each case, if such Person is a Person other than the Trustee). The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent.
If the Company fails to maintain a Registrar, Paying Agent, Conversion Agent or Bid Solicitation Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 9.7. The Company or any Subsidiary
or an Affiliate of either of them may act as Paying Agent, Registrar, Conversion Agent or 

  

 12 

 
co-registrar. None of the Company or any Subsidiary or any Affiliate of any of them may act as Bid Solicitation Agent. 
  
 The Company hereby initially appoints the Trustee as Registrar, Paying Agent,
Conversion Agent and Bid Solicitation Agent in connection with the Securities. 
  
 Section 2.4. Paying Agent to Hold Cash and Securities in Trust. 
  
 Except as otherwise provided herein, prior to 10:00 a.m., New York City time, on each due date of payments in respect of, or delivery of Common Stock or
Applicable Stock upon conversion of, any Security, the Company shall deposit with the Paying Agent Cash (in immediately available funds if deposited on the due date) or with the Conversion Agent such number of shares of Common Stock and/or
Applicable Stock sufficient to make such payments or deliveries when so becoming due. The Company shall require each Paying Agent or Conversion Agent, as applicable (other than the Trustee), to agree in writing that such Agent shall hold in trust
for the benefit of Securityholders or the Trustee all Cash, Common Stock and Applicable Stock, as applicable, held by such Agent for the making of payments or deliveries in respect of the Securities and shall notify the Trustee of any default by the
Company in making any such payment or delivery. If the Company, a Subsidiary or an Affiliate of any of them acts as Paying Agent or Conversion Agent, as applicable, it shall segregate the money, Common Stock and Applicable Stock, as applicable, held
by it as Paying Agent or Conversion Agent, as applicable and hold it as a separate trust fund. 
  
 The Company at any time may require a Paying Agent or Conversion Agent, as applicable to pay all Cash, Common Stock and Applicable Stock, as applicable, held by it to the Trustee, and to account for any funds and
Common Stock or Applicable Stock, as applicable, disbursed by it, and the Trustee may at any time during the continuance of any default, upon the written request to the Paying Agent or Conversion Agent, as applicable, require such Paying Agent or
Conversion Agent, as applicable to forthwith pay to the Trustee all Cash, Common Stock and Applicable Stock, as applicable, so held in trust. Upon doing so, the Paying Agent or Conversion Agent, as applicable shall have no further liability for such
Cash, Common Stock or Applicable Stock, as applicable. 
  
 Section
2.5. Securityholder Lists. 
  
 The Trustee shall preserve
in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Securityholders. If the Trustee is not the Registrar, the Company shall cause to be furnished to the Trustee on or before each
semiannual interest payment date and at such other times as the Trustee may request in writing a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Securityholders. 
  
 Section 2.6. Transfer and Exchange. 
  
 (a) Subject to compliance with any applicable additional requirements
contained in Section 2.12, when a Security is presented to the Registrar with a request to register a transfer thereof or to exchange such Security for an equal principal amount of Securities of 

  

 13 

 
other authorized denominations, the Registrar shall register the transfer or make the exchange as requested; provided, however, that every Security
presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by an assignment form and, if applicable, a transfer certificate, each in the form included in Exhibit A attached hereto and in form satisfactory
to the Registrar and each duly executed by the Holder thereof or its attorney duly authorized in writing. To permit registration of transfers and exchanges, upon surrender of any Security for registration of transfer or exchange at an office or
agency maintained for such purpose pursuant to Section 2.3, the Company shall execute, and the Trustee shall authenticate Securities of a like aggregate principal amount at the Registrar’s request. Any transfer or exchange shall be without
charge, except that the Company or the Registrar may require payment of a sum sufficient to pay all taxes, assessments or other governmental charges that may be imposed in connection with the transfer or exchange of the Securities from the
Securityholder requesting such transfer or exchange. 
  
 Neither
the Company, the Registrar nor the Trustee shall be required to exchange or register a transfer of (i) any Securities selected for redemption (except, in the case of Securities to be redeemed in part, the portion thereof not to be redeemed), (ii)
any Securities in respect of which a Repurchase Notice or a Repurchase Event 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 repurchased
in part, the portion thereof not to be repurchased) or (iii) any Securities for a period of 15 days before the mailing of a notice of redemption of Securities to be redeemed. 
  
 All Securities issued upon any transfer or exchange of Securities shall be valid obligations of the Company, evidencing the
same debt and entitled to the same benefits under this Indenture, as the Securities surrendered upon such transfer or exchange. 
  
 (b) Any Registrar appointed pursuant to Section 2.3 shall provide to the Trustee such information as the Trustee may reasonably require in connection with
the delivery by such Registrar of Securities upon transfer or exchange of Securities. 
  
 (c) Each Holder of a Security agrees to indemnify the Company, the Registrar and the Trustee against any liability that may result from the transfer, exchange or assignment of such Holder’s Security in violation
of any provision of this Indenture and/or applicable United States federal or state securities law. 
  
 The Trustee 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 other 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. 
  

 14 

 Section 2.7. Replacement Securities. 
  
 If (a) any mutilated Security is surrendered to the Company, the Registrar
or the Trustee, or (b) the Company, the Registrar and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company, the Registrar 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, the Registrar or the Trustee that such Security has been acquired by a bona fide or protected 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 by the Company pursuant to Article III or repurchased by the Company pursuant to Article IV or V, the Company in its
discretion may, instead of issuing a new Security, pay, redeem or repurchase such Security, as the case may be to the Holder of record. 
  
 Upon the issuance of any new Securities under this Section 2.7, the Company may require the payment of a sum sufficient to cover any tax, assessment or
other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee or the Registrar) connected therewith. 
  
 Every new Security issued pursuant to this Section 2.7 in lieu of any mutilated, destroyed, lost or stolen Security shall
constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and
proportionately with any and all other Securities duly issued hereunder. 
  
 The provisions of this Section 2.7 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

  
 Section 2.8. Outstanding Securities; Determinations of
Holders’ Action. 
  
 Securities outstanding at any time
are all the Securities authenticated by the Trustee, except for those cancelled by it, those paid, redeemed or repurchased pursuant to Section 2.7, those delivered to it for cancellation and those described in this Section 2.8 as not outstanding.

  
 A Security does not cease to be outstanding because the
Company or an Affiliate thereof holds the Security; provided, however, that in determining whether the Holders of the requisite principal amount of Securities have given or concurred in any request, demand, authorization, direction, notice,
consent, waiver, or other Act hereunder, Securities owned by the Company or any other obligor upon the Securities or any Affiliate of the Company or such other obligor shall be disregarded and deemed not to be outstanding, except that, in
determining 

  

 15 

 
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.

  
 If a Security is replaced pursuant to Section 2.7, the
replaced Security ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide or protected purchaser unaware that such Security has been replaced. 
  
 If the Paying Agent holds, in accordance with the terms of this Indenture,
prior to 10:00 a.m., New York City time, on the Stated Maturity or a Redemption Date or on the Business Day immediately following a Repurchase Date or a Repurchase Event Repurchase Date, as the case may be, Cash or securities, if permitted
hereunder, sufficient to pay Securities payable, then immediately after such Stated Maturity, Redemption Date, Repurchase Date or Repurchase Event Repurchase Date, as the case may be, such Securities shall cease to be outstanding and interest and
Liquidated Damages Amount, if any, on such Securities shall cease to accrue. 
  
 If a Security is converted in accordance with Article XII, then from and after the time of conversion on the date of conversion, such Security shall cease to be outstanding and interest and Liquidated Damages Amount,
if any, on such Security shall cease to accrue. 
  
 Section 2.9.
Temporary Securities. 
  
 Pending the preparation of
definitive Securities, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as conclusively
evidenced by their execution of such Securities. 
  
 If temporary
Securities are issued, the Company will cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary Securities shall be exchangeable for definitive Securities upon surrender of
the temporary Securities at the office or agency of the Company designated for such purpose pursuant to Section 2.3, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of authorized denominations. Until so exchanged the temporary Securities shall in all respects be entitled to the same benefits under
this Indenture as definitive Securities. 
  
 Section 2.10.
Cancellation. 
  
 All Securities surrendered for payment,
repurchase by the Company pursuant to Articles IV or V, conversion, redemption or registration of transfer or exchange shall, if 

  

 16 

 
surrendered to any person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to
the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. The Company may
not issue new Securities to replace Securities it has paid or delivered to the Trustee for cancellation or that any Holder has converted pursuant to Article XII. 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 (whether in Cash, Common Stock or Applicable Stock) of
principal of, Redemption Price, Repurchase Price or Repurchase Event Repurchase Price, and interest and Liquidated Damages Amount, if any, on, the Security, for the purpose of receiving Cash, Common Stock or Applicable Stock upon conversion and for
all other purposes whatsoever, whether or not such Security is 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. Additional Transfer and Exchange Requirements.

  
 (a) Transfer and Exchange of Global Securities.

  
 (i) Certificated Securities shall be issued
in exchange for interests in the Global Securities only if (x) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for the Global Securities or if it at any time ceases to be a “clearing agency”

and deliver Certificated Securities in an aggregate principal amount equal to the principal amount of such Global Securities in exchange therefor. Only Restricted Certificated Securities shall be issued in exchange for beneficial interests in
Restricted Global Securities, and only Unrestricted Certificated Securities shall be issued in exchange for beneficial interests in Unrestricted Global Securities. Certificated Securities issued in exchange for beneficial interests in Global
Securities shall be registered in such names and shall be in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver or
cause to be delivered such Certificated Securities to the Persons in whose name such Securities are so registered. Such exchange shall be effected in accordance with the Applicable Procedures. 
  

 17 

 (ii) Notwithstanding any other provisions of this Indenture other than the provisions set
forth in Section 2.12(a)(i), a Global Security may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or
any such nominee to a successor Depositary or a nominee of such successor Depositary. 
  
 (b) Transfer and Exchange of Certificated Securities. In the event that Certificated Securities are issued in exchange for beneficial interests in Global Securities in accordance with Section 2.12(a)(i), and,
on or after such event, Certificated Securities are presented by a Holder to the Registrar with a request: 
  
 (x) to register the transfer of the Certificated Securities to a person who will take delivery thereof in the form of Certificated
Securities only; or 
  
 (y) to exchange such
Certificated Securities for an equal principal amount of Certificated Securities of other authorized denominations, 
  
 such Registrar shall register the transfer or make the exchange as requested; provided, however, that the Certificated Securities presented or surrendered for
register of transfer or exchange: 
  
 (i) shall
be duly endorsed or accompanied by a written instrument of transfer in accordance with the proviso to the first paragraph of Section 2.6; and 
  
 (ii) in the case of a Restricted Certificated Security, such request shall be accompanied by the following additional information and
documents, as applicable:

Restricted Certificated Security is being delivered to the Registrar by a Holder for registration in the name of such Holder, without transfer, or such Restricted Certificated Security is being transferred to the Company or a Subsidiary of the
Company, a certification to that effect from such Holder (in substantially the form set forth in the Transfer Certificate); 
  
 (B) if such Restricted Certificated Security is being transferred to a person the Holder reasonably believes is a QIB in accordance with
Rule 144A, or pursuant to an effective registration statement under the Securities Act or in compliance with Rule 904 under the Securities Act, a certification to that effect from such Holder (in substantially the form set forth in the Transfer
Certificate); 
  
 (C) if such Restricted
Certificated Security is being issued to an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act), a certificate to that effect from the Holder (in substantially the form set forth in
the Transfer Certificate) and a signed letter containing certain representations and agreements relating to the restrictions on transfer of the Securities in the form obtained from the Trustee; 
  

 18 

 (D) if such Restricted Certificated Security is being transferred pursuant to an
exemption from the registration requirements of the Securities Act in accordance with Rule 144 pursuant to and in compliance with an exemption from the registration requirements under the Securities Act, a certification to that effect from the
Holder (in substantially the form set forth in the Transfer Certificate) and if the Company or the Registrar so requests, a customary Opinion of Counsel, certificates and other information reasonably acceptable to the Company and the Registrar to
the effect that such transfer does not require registration under the Securities Act. 
  
 (c) Transfer of a Beneficial Interest in a Restricted Global Security for a Beneficial Interest in an Unrestricted Global Security. Any person having a beneficial interest in a Restricted Global Security may
upon request, subject to the Applicable Procedures, transfer such beneficial interest to a person who is required or permitted to take delivery thereof in the form of an Unrestricted Global Security. Upon receipt by the Trustee of written
instructions, or such other form of instructions as is customary for the Depositary, from the Depositary or its nominee on behalf of any person having a beneficial interest in a Restricted Global Security and the following additional information and

pursuant to an exemption from the registration requirements of the Securities Act in accordance with Rule 144, a certification to that effect from the Holder (in substantially the form set forth in the Transfer Certificate) and, if the Company or
the Trustee so requests, a customary Opinion of Counsel, certificates and other information reasonably acceptable to the Company and the Register to the effect that such transfer does not require registration under the Securities Act, 
  
 the Registrar shall reduce or cause to be reduced the aggregate principal amount of the
Restricted Global Security by the appropriate principal amount and shall increase or cause to be increased the aggregate principal amount of the Unrestricted Global Security by a like principal amount. Such transfer shall otherwise be effected in
accordance with the Applicable Procedures. If no Unrestricted Global Security is then outstanding, the Company shall execute and the Trustee shall, upon receipt of a Company Order (which the Company agrees to deliver promptly), authenticate and
deliver an Unrestricted Global Security. 
  
 (d) Transfer of a
Beneficial Interest in an Unrestricted Global Security for a Beneficial Interest in a Restricted Global Security. Any person having a beneficial interest in an Unrestricted Global Security may upon request, subject to the Applicable Procedures,
transfer such beneficial interest to a person who is required or permitted to take delivery thereof in the form of a Restricted Global Security. Upon receipt by the Trustee of written instructions, or such 

  

 19 

 
other form of instructions as is customary for the Depositary, from the Depository or its nominee on behalf of any person having a beneficial interest in an
Unrestricted Global Security and the following additional information and documents in such form as is customary for the Depositary, from the Depositary or its nominee on behalf of the person having such beneficial interest in the Unrestricted
Global Security (all of which may be submitted by facsimile or electronically): 
  
 (i) a certification from the Holder (in substantially the form set forth in the Transfer Certificate) to the effect that such beneficial
interest is being transferred to a person that the transferor reasonably believes is a QIB in accordance with Rule 144A; or 
  
 (ii) a certification from the Holder (in substantially the form set forth in the Transfer Certificate) to the effect that such beneficial
interest is being transferred in compliance with Rule 904 under the Act; or 
  
 (iii) a certification from the Holder (in substantially the form set forth in the Transfer Certificate) to the effect that such beneficial interest is being transferred to an institutional “accredited
investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act) and a signed letter containing certain representations and agreements relating to the restrictions on transfer of the Securities in the form obtained from the
Trustee. 
  
 The Registrar shall reduce or cause to be reduced the aggregate
principal amount of the Unrestricted Global Security by the appropriate principal amount and shall increase or cause to be increased the aggregate principal amount of the Restricted Global Security by a like principal amount. Such transfer shall
otherwise be effected in accordance with the Applicable Procedures. If no Restricted Global Security is then outstanding, the Company shall execute and the Trustee shall, upon receipt of a Company Order (which the Company agrees to deliver
promptly), authenticate and deliver a Restricted Global Security. 
  
 (e) Transfers of Certificated Securities for Beneficial Interest in Global Securities. In the event that Certificated Securities are issued in exchange for beneficial interests in Global Securities and, thereafter, the events or
conditions specified in Section 2.12(a)(i) which required such exchange shall cease to exist, the Company shall mail notice to the Trustee and to the Holders stating that Holders may exchange Certificated Securities or interests in Global Securities
by complying with the procedures set forth in this Indenture and briefly describing such procedures and the events or circumstances requiring that such notice be given. Thereafter, if Certificated Securities are presented by a Holder to a Registrar

of such Certificated Securities to a person who will take delivery thereof in the form of a beneficial interest in a Global Security, which request shall specify whether such Global Security will be a Restricted Global Security or an Unrestricted
Global Security, or 
  
 (y) to exchange such
Certificated Securities for an equal principal amount of beneficial interests in a Global Security, which beneficial interests will be owned by the Holder transferring such Certificated Securities (provided that in the case of such an 

  

 20 

 
exchange, Restricted Certificated Securities may be exchanged only for Restricted Global Securities and Unrestricted Certificated Securities may be exchanged
only for Unrestricted Global Securities), the Registrar shall register the transfer or make the exchange as requested by canceling such Certificated Security and causing the aggregate principal amount of the applicable Global Security to be
increased accordingly and, if no such Global Security is then outstanding, the Company shall issue and the Trustee shall, upon receipt of a Company Order (which the Company agrees to deliver promptly) authenticate and deliver a new Global Security;

  
 provided, however, that the Certificated Securities presented or
surrendered for registration of transfer or exchange: 
  
 (i) shall be duly endorsed or accompanied by a written instrument of transfer in accordance with the proviso to Section 2.6(a);

 (B) if such Restricted Certificated Security is being transferred in compliance with Rule 904 under the
Act, certification to that effect from such Holder (in substantially the form set forth in the Transfer Certificate); or

 (C) if such Restricted Certificated Security is being transferred to an institutional
“accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act), certification to that effect from such Holder (in substantially the form set forth in the Transfer Certificate) and a signed letter containing
certain representations and agreements relating to the restrictions on transfer of the Securities in the form obtained from the Trustee; 
  
 (iv) in the case of an Unrestricted Certificated Security to be transferred or exchanged for a beneficial interest in an Unrestricted

 (B) if such Unrestricted Certificated Security is being
transferred in compliance with Rule 904 under the Act, certification to that effect from such Holder (in substantially the form set forth in the Transfer Certificate); or

Securities issued in exchange therefor or upon registration of transfer or replacement thereof) shall bear a legend in substantially the form called for by footnote 2 to Exhibit A attached hereto (each a “Transfer Restricted
Security”), for so long as it is required by this Indenture to bear such legend. Each Transfer Restricted Security shall have attached thereto a certificate (a “Transfer Certificate”) in substantially the form
called for by footnote 5 to Exhibit A attached hereto. 
  
 (ii) Upon any sale or transfer of a Transfer Restricted Security (x) after the expiration of the holding period applicable to sales of the Securities under Rule 

  

 22 

 
144(k) of the Securities Act, (y) pursuant to Rule 144 or (z) pursuant to an effective registration statement under the Securities Act: 
  
 (A) in the case of any Restricted Certificated Security,
any Registrar shall permit the Holder thereof to exchange such Restricted Certificated Security for an Unrestricted Certificated Security, or (under the circumstances described in Section 2.12(e)) to transfer such Restricted Certificated Security to
a transferee who shall take such Security in the form of a beneficial interest in an Unrestricted Global Security, and in each case shall rescind any restriction on the transfer of such Security; provided, however, that the Holder of such
Restricted Certificated Security shall, in connection with such exchange or transfer, comply with the other applicable provisions of this Section 2.12; and 
  
 (B) in the case of any beneficial interest in a Restricted Global Security, the Trustee shall permit the beneficial owner thereof to
transfer such beneficial interest to a transferee who shall take such interest in the form of a beneficial interest in an Unrestricted Global Security and shall rescind any restriction on transfer of such beneficial interest; provided,
however, that such Unrestricted Global Security shall continue to be subject to the provisions of Section 2.12(a)(ii); and provided, further, that the owner of such beneficial interest shall, in connection with such transfer,
comply with the other applicable provisions of this Section 2.12. 
  
 (iii) Upon the exchange, registration of transfer or replacement of Securities not bearing the legend described in paragraph (1) above, the Company shall execute, and the Trustee shall authenticate and deliver,
Securities that do not bear such legend and that do not have a Transfer Certificate attached thereto. 
  
 (iv) After the expiration of the holding period pursuant to Rule 144(k) of the Securities Act, the Company may with the consent of the
Holder of a Restricted Global Security or a Restricted Certificated Security, remove any restriction of transfer on such Security, and the Company shall execute, and the Trustee shall authenticate and deliver, Securities that do not bear such legend
and that do not have a Transfer Certificate attached thereto. 
  
 (v) Until the expiration of the holding period applicable to sales of the Securities under Rule 144(k) of the Securities Act or a transfer pursuant to Rule 144 or pursuant to an effective registration statement under

 (g) Transfers to the Company. Nothing contained in this Indenture or in the Securities shall prohibit the sale or
other transfer of any Securities (including beneficial interests in Global Securities) to the Company or any of its Subsidiaries, which Securities shall thereupon be cancelled in accordance with Section 2.10. 
  

 23 

 Section 2.13. CUSIP Numbers. 
  
 The Company may issue the Securities with one or more “CUSIP” numbers (if then generally in use), and, if so, the
Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such
numbers. The Company will promptly notify the Trustee of any change in the CUSIP numbers. 
  
 Section 2.14. Ranking. 
  
 The indebtedness of the Company arising under or in connection with this Indenture and every outstanding Security issued under this Indenture from time to time constitutes and will constitute a senior unsecured general obligation of the
Company,| and ranking equally with| existing and future senior unsecured Indebtedness of the Company and ranking senior in right of payment to any future Indebtedness of the Company that is expressly made subordinate to the Securities by the terms
of such Indebtedness. 
  
 For purposes of this Section 2.14 only,
“Indebtedness” means, without duplication, the principal or face amount of: 
  
 (a) all obligations for borrowed money; 
  
 (b) all obligations evidenced by bonds, debentures, notes or other similar instruments; 
  
 (c) all obligations in respect of letters of credit or bankers acceptances or similar instruments (or reimbursement obligations with respect thereto);

  
 (d) all obligations to pay the deferred purchase price of
property or services, except trade accounts payable arising in the ordinary course of business; 
  
 (e) all obligations as lessee which are capitalized in accordance with generally accepted accounting principles; and 
  
 (f) all Indebtedness of others guaranteed by the Company or any of its
Subsidiaries or for which the Company or any of its Subsidiaries is legally responsible or liable (whether by agreement to purchase indebtedness of, or to supply funds or to invest in, others). 
  
 ARTICLE III 
 REDEMPTION 
  
 Section 3.1. The Company’s Right to Redeem; Notice to Trustee. 
  
 Prior to January 15, 2009, the Securities will not be redeemable at the Company’s option. Beginning on January 15, 2009, the Company, at its option, may redeem the Securities 

  

 24 

 
in accordance with this Article III for Cash at any time as a whole, or from time to time in part, at a redemption price equal to 100% of the principal
amount of Securities to be redeemed plus any accrued and unpaid interest and Liquidated Damages Amount, if any, on those Securities to, but not including, the Redemption Date (the “Redemption Price”). 
  
 In the event that the Company elects to redeem the Securities on a date that
is on or after any Regular Record Date but on or before the corresponding Interest Payment Date, the Company shall be required to pay any accrued and unpaid interest and Liquidated Damages Amount, if any, to the same Holder to whom the Company pays
the principal of such Security regardless of whether such Holder was the registered Holder on the Regular Record Date immediately preceding such Redemption Date and, if the Holder to whom the Company pays the principal, interest and Liquidation
Damages Amount, if any, was not the registered Holder on the Regular Record Date, such payment shall be in lieu of payment to the registered Holder on such Regular Record Date. 
  
 If the Company elects to redeem Securities, it shall notify the Trustee in writing of the Redemption Date, the principal
amount of Securities to be redeemed and the Redemption Price. The Company shall give this notice to the Trustee by a Company Order at least 35 days before the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee).

  
 Section 3.2. Selection of Securities to Be Redeemed.

  
 If fewer than all of the outstanding 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 any other method the Trustee considers fair and appropriate. The Trustee shall make the
selection within five Business Days after it receives the notice provided for in Section 3.1 from outstanding Securities not previously called for redemption. 
  

Securities and portions of Securities that the Trustee selects shall be in principal amounts of $1,000 or a multiple of $1,000. Provisions of this
Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company promptly of the Securities or portions of the Securities to be redeemed. 
  
 Securities and portions of Securities that are to be redeemed are convertible
by the Holder until 5:00 p.m., New York City time, on the Business Day immediately preceding the Redemption Date. If any Security selected for partial redemption is converted in part before termination of the conversion right with respect to the
portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities which have been converted during a selection of Securities to be redeemed may be
treated by the Trustee as outstanding for the purpose of such selection. 
  
 Section 3.3. Notice of Redemption. 
  
 At least 30 days but not more than 60 days before a Redemption Date, the Company shall mail a notice of redemption by first-class mail, postage prepaid, to each Holder of Securities to be redeemed. 
  

 25 

 The notice of redemption shall identify the Securities to be redeemed and shall state: 
  
 (a) the Redemption Date; 
  
 (b) the Redemption Price; 
  
 (c) the Conversion Rate; 
  
 (d) the name and address of the Paying Agent and Conversion Agent;

  
 (e) that Securities called for redemption may be converted at
any time prior to 5:00 p.m., New York City time, on the Business Day preceding the Redemption Date; 
  
 (f) that Holders who want to convert their Securities must satisfy the requirements set forth in Article XII; 
  
 (g) that Securities called for redemption must be surrendered to the Paying
Agent to collect the Redemption Price; 
  
 (h) in the case of any
Security redeemed in part, that the Holder of such Security will receive a new Security or Securities, of authorized denominations for the principal amount thereof remaining unredeemed; 
  
 (i) 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; 
  
 (j) that,
unless the Company defaults in making payment of such Redemption Price, interest and Liquidated Damages Amount, if any, on Securities called for redemption will cease to accrue on and after the Redemption Date; 
  
 (k) the CUSIP number(s) of the Securities to be redeemed; and 
  
 (l) any other information the Company at the discretion of the Company.

  
 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, however, that the Company makes such request at least five Business Days (unless a shorter period shall 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 3.3; provided, further, that the text of the notice of redemption shall be prepared by the Company. 
  
 Section 3.4. Effect of Notice of Redemption. 
  
 Once notice of redemption is given, Securities called for redemption become
due and payable on the Redemption Date and at the Redemption Price, except for Securities which are converted in accordance with the terms of this Indenture. Upon surrender to the Paying Agent, such Securities shall be paid at the Redemption Price.

  

 26 

 Section 3.5. Deposit of Redemption Price. 
  
 Prior to 10:00 a.m., New York City time, on the applicable Redemption Date,
the Company shall deposit with the Paying Agent (or if the Company or a Subsidiary or an Affiliate of any of them is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 2.4) an amount of Cash (in immediately
available funds if deposited on the Redemption Date) sufficient to pay the aggregate Redemption Price of all Securities or portions thereof which are to be redeemed as of such Redemption 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. 
  
 If the Paying Agent holds, in accordance with the terms hereof, at 10:00 a.m., New York City time, on the applicable Redemption Date, Cash sufficient to
pay the Redemption Price of any Securities for which notice of redemption is given, then, on such Redemption Date, such Securities will cease to be outstanding and interest and Liquidated Damages Amount, if any, on such Securities will cease to
accrue, whether or not such Securities are delivered to the Paying Agent, and the rights of the Holders in respect thereof shall terminate (other than the right to receive the Redemption Price upon delivery of such Securities). 
  
 Section 3.6. Securities Redeemed in Part. 
  
 Any Certificated Security which is to be redeemed only in part shall be
surrendered at the office of the Paying Agent and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without charge, a new Security or Securities, of any authorized denomination as requested by
such Holder in aggregate principal amount equal to the unredeemed portion of the Security surrendered. 
  
 Section 3.7. Repayment to the Company. 
  
 To the extent that the aggregate amount of Cash deposited by the Company pursuant to Section 3.5 exceeds the aggregate Redemption Price of the Securities
or portions thereof which the Company is redeeming as of the Redemption Date, then, promptly after the Redemption Date, the Paying Agent shall return any such excess to the Company.

satisfactory to 

  

 28 

 
the Trustee) prior to the date by which such notice of repurchase right must be given to the Holder in accordance with this Section 4.1(b); provided,
further, that the text of the notice of repurchase right shall be prepared by the Company. 
  
 (c) A Holder may exercise its right specified in Section 4.1(a) upon delivery of a written notice of repurchase (a “Repurchase Notice”), substantially in the form of Exhibit C hereto, to the Paying

 The Company shall repurchase from the Holder thereof, pursuant to this

 Upon receipt by the Paying Agent of the Repurchase Notice specified in
Section 4.1(c), the Holder of the Security in respect of which such Repurchase Notice was given shall (unless such Repurchase Notice is withdrawn as specified in the following paragraph) thereafter be entitled to receive solely the Repurchase Price
with respect to such Security. Securities in respect of which a Repurchase Notice has been given by the Holder thereof may not be converted pursuant to Article XII on or after the date of the delivery of such Repurchase Notice unless such Repurchase
Notice has first been validly withdrawn as specified in the following paragraph. 
  
 A 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 at any time prior to 5:00 p.m., New York City time,

aggregate Repurchase Price of all the Securities or portions thereof which are to be repurchased on such Repurchase Date. 
  
 If the Paying Agent holds, in accordance with the terms hereof, at 10:00 a.m., New York City time, on the applicable Repurchase Date, Cash sufficient to

Liquidated Damages Amount, if any, on such Securities will cease to accrue, whether or not such Securities are delivered to the Paying Agent, and the rights of the Holders in respect thereof shall terminate (other than the right to receive the
Repurchase Price upon delivery of such Securities). 
  

 30 

 Section 4.5. Securities Repurchased in Part. 
  
 Any Certificated Security which is to be repurchased only in part shall be
surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such
Holder’s attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without charge, a new Security or Securities, of any authorized denomination as requested

 (b) file the related Schedule TO (or any successor schedule, form or report) under the Exchange Act; and 
  
 (c) otherwise comply with all federal and state securities laws so as to
permit the rights and obligations under this Article IV to be exercised in the time and in the manner specified therein. 
  
 To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Article IV, the Company’s compliance
with such laws and regulations shall not in and of itself cause a breach of its obligations under this Article IV. 
  
 Section 4.7. Repayment to the Company. 
  
 To the extent that the aggregate amount of Cash deposited by the Company pursuant to Section 4.4 exceeds the aggregate Repurchase Price of the Securities

Securities to be repurchased, plus accrued and unpaid interest and Liquidated Damages Amount, if any, on those notes to, but not including, the Repurchase Event Repurchase Date (the “Repurchase Event Repurchase Price”),
subject to satisfaction by or on behalf of any Holder of the requirements set forth in Section 5.1(c). The repurchase event repurchase date must be within 30 days after the date of the mailing of the Repurchase Event Company Notice under Section 5.1
(b) (the “Repurchase Event Repurchase Date”).  
  
 A “Repurchase Event” shall be deemed to have occurred upon the occurrence of either a “change in control” or a “termination of trading” where: 
  
 (i) a “change in control” will be deemed to have
occurred at such time as: 
  
 (A) any person or
group is or becomes the beneficial owner, directly or indirectly, of 50% or more of the Company’s voting stock; 
  
 (B) the Company consolidates with, or merges with or into, another person or any person consolidates with, or merges with or into, the
Company, in any such event other than pursuant to a transaction in which the persons that beneficially owned, directly or indirectly, the shares of voting stock immediately prior to such transaction beneficially own immediately after such
transaction, directly or indirectly, shares of voting stock representing not less than a majority of the total voting power of all outstanding classes of voting stock of the continuing or surviving corporation in substantially the same proportion as
such ownership prior to the transaction; 
  
 (C)
a majority of the members of the Company’s board of directors are not continuing directors (as defined below); 
  
 (D) the sale, lease, transfer or other conveyance or disposition of all or substantially all of the Company’s assets or property to
any person or group; or 
  
 (E) the Company is
liquidated or dissolved, or its stockholders approve any plan or proposal for the liquidation or dissolution of the Company; 
  

 32 

 Provided, however, 
  
 (1) a “change in control” will not be deemed to have occurred if the last sale price of the Common Stock for any five Trading
Days during the ten Trading Days immediately preceding the change in control is at least equal to or exceeds 120% of the conversion price in effect on such Trading Day; or 
  
 (2) a “change in control” will not be deemed to have occurred under Section 5.1.(a)(i)(A) or
Section 5.1.(a)(i)(B), if in the case of a merger or consolidation, all of the consideration (excluding cash payments for fractional shares and cash payments pursuant to dissenters’ appraisal rights) in the merger or consolidation constituting
the change in control consists of common stock traded on a United States national securities exchange or quoted on the Nasdaq National Market (or which will be so traded or quoted when issued or exchanged in connection with such change in control)
and as a result of such transaction or transactions the debentures become convertible solely into such common stock; and 
  
 (3) a “change of control” under Section 5.1.(a)(i)(C) above shall not be deemed to have occurred if it is concurrent and in
connection with a change of control transaction covered by items (1) or (2) immediately above, and from and after any such transactions, the term “date of this Indenture” as used in the definition of continuing director (as defined below)
shall refer instead to the effective date of such transaction. 
  
 (ii) a “termination of trading” shall occur if the Company’s Applicable Stock is neither listed for trading on a United States national or regional securities exchange nor approved for trading on the
NASDAQ National Market, NASDAQ SmallCap Market or any other established United States system of automated dissemination of quotations of securities prices. 
  
 For purposes of this section, a “continuing director” means, as of any date of determination, any member of the Company’s board of directors who:

  
 (1) was a member of such board of directors
on the date of this Indenture; or 
  
 (2) was
nominated for election or elected to such board of directors with the approval of: (a) a majority of the continuing directors who were members of such board at the time of such nomination or election, or (b) a nominating committee, a majority of
which committee shall be continuing directors as the time of such nomination or election. 
  
 For purposes of this section, the terms “person” or “group” shall have the meanings used for purposes of Sections 13(d) and 14(d) of the Exchange Act. 
  
 For purposes of this section, the terms “beneficial owner,” “beneficially
owned” and similar terms shall have the meanings set forth in Rule 13d-3 under the Exchange Act. 
  
 For purposes of this section, the term “voting stock” shall mean the Company’s Capital Stock entitled to vote generally in the election of directors. 
  

 33 

 (b) Notice of Repurchase Event. No later than 20 days after the occurrence of a Repurchase Event,
the Company shall mail a written notice of Repurchase Event (the “Repurchase Event Company Notice”) by first class mail to the Trustee and to each Holder (and to beneficial owners as required by applicable law). The notice shall

convertible pursuant to Article XII only if the Repurchase Event Repurchase Notice has been withdrawn in accordance with the terms of this Indenture; 
  
 (ix) that the Securities must be surrendered to the Paying Agent to collect payment; 
  
 (x) that the Repurchase Event Repurchase Price for any
Security as to which a Repurchase Event Repurchase Notice has been duly given and not withdrawn will be paid promptly following the later of the Fundamental Repurchase Date and the time of surrender of such Security; 
  
 (xi) the procedures the Holder must follow to exercise its
Repurchase Event repurchase right under this Section 5.1; 
  
 (xii) the conversion rights, if any, of the Securities; 
  
 (xiii) the procedures for withdrawing a Repurchase Event Repurchase Notice; 
  

 34 

 (xiv) that, unless the Company defaults in making payment of such Repurchase Event
Repurchase Price, interest and Liquidated Damages Amount, if any, on Securities surrendered for repurchase by the Company will cease to accrue on and after the Repurchase Event Repurchase Price; and 
  
 (xv) the CUSIP number(s) of the Securities. 
  
 At the Company’s request, the Trustee shall give the Repurchase Event
Company Notice in the Company’s name and at the Company’s expense; provided, however, the Company makes such request at least three Business Days (unless a shorter period shall be satisfactory to the Trustee) prior to the date by
which such Repurchase Event Company Notice must be given to the Holders in accordance with this Section 5.1(b); provided, further, that the text of the Repurchase Event Company Notice shall be prepared by the Company. 
  
 (c) Repurchase Event Repurchase Notice. A Holder may exercise its
right specified in Section 5.1(a) upon delivery of a written notice of repurchase (a “Repurchase Event Repurchase Notice”), substantially in the form of Exhibit D hereto, to the Paying Agent at any time prior to 5:00 p.m., New York
City time, on the Business Day immediately preceding the Repurchase Event Repurchase Date, stating: 
  
 (i) the certificate number of the Security which the Holder will deliver to be repurchased if Certificated Securities have been issued;

  
 (ii) the portion of the principal amount of
the Security which the Holder will deliver to be repurchased, which portion must be $1,000 or a multiple of $1,000; 
  
 (iii) that such Security shall be repurchased on the Repurchase Event Repurchase Date pursuant to the terms and conditions specified in
the Securities and in this Indenture; and 
  
 The delivery of such
Security to the Paying Agent with, or at any time after delivery of, the Repurchase Event Repurchase Notice (together with all necessary endorsements) at the offices of the Paying Agent shall be a condition to the receipt by the Holder of the
Repurchase Event Repurchase Price therefor; provided, however, that such Repurchase Event Repurchase Price shall be so paid pursuant to this Section 5.1 only if the Security so delivered to the Paying Agent shall conform in all respects to
the description thereof set forth in the related Repurchase Event Repurchase Notice. 
  
 The Company shall repurchase from the Holder thereof, pursuant to this Section 5.1, a portion of a Security, so long as the principal amount of such portion is $1,000 or a 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 of such Security. 
  
 Any repurchase by the Company contemplated pursuant to the provisions of this Section 5.1 shall be consummated by the delivery of the consideration to be
received by the 

  

 35 

 
Holder promptly following the later of the Repurchase Event Repurchase Date and the time of delivery of the Security. 
  
 Notwithstanding anything contained herein to the contrary, any Holder
delivering to the Paying Agent the Repurchase Event Repurchase Notice contemplated by this Section 5.1(c) shall have the right to withdraw such Repurchase Event Repurchase Notice at any time prior to 5:00 p.m., New York City time, on the Business
Day immediately preceding the Repurchase Event Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 5.3. 
  

The Paying Agent shall promptly notify the Company of the receipt by it of any Repurchase Event Repurchase Notice or written notice of withdrawal
thereof. 
  
 Section 5.2. Manner of Payment of Repurchase Event
Repurchase Price. 
  
 The Securities to be repurchased with
respect to any Repurchase Event Repurchase Date pursuant to 5.1(a) will be paid in cash. 
  
 Section 5.3. Effect of Repurchase Event Repurchase Notice. 
  
 Upon receipt by the Paying Agent of the Repurchase Event Repurchase Notice specified in Section 5.1(c), the Holder of the Security in respect of which
such Repurchase Event Repurchase Notice was given shall (unless such Repurchase Event Repurchase Notice is withdrawn as specified in the following paragraph) thereafter be entitled to receive solely the Repurchase Event Repurchase Price with respect
to such Security. Securities in respect of which a Repurchase Event Repurchase Notice has been given by the Holder thereof may not be converted pursuant to Article XII on or after the date of the delivery of such Repurchase Event Repurchase Notice
unless such Repurchase Event Repurchase Notice has first been validly withdrawn as specified in the following paragraph. 
  
 A Repurchase Event 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 Event Repurchase Notice at any time prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Repurchase Event Repurchase Date, specifying:

 Section 5.4. Deposit of Repurchase Event Repurchase Price. 
  
 Prior to 10:00 a.m., New York City time, on the applicable Repurchase Event
Repurchase Date, the Company shall deposit with the Paying Agent (or if the Company or a Subsidiary or an Affiliate of any of them is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 2.4) an amount of Cash (in
immediately available funds if deposited on such Business Day), sufficient to pay the aggregate Repurchase Event Repurchase Price of all the Securities or portions thereof which are to be repurchased on such Repurchase Event Repurchase Date.

  
 If the Paying Agent holds, in accordance with the terms
hereof, at 10:00 a.m., New York City time, on the applicable Repurchase Event Repurchase Date, Cash sufficient to pay the Repurchase Event Repurchase Price of any Securities for which a Repurchase Event Repurchase Notice has been tendered and not
withdrawn pursuant to Section 5.3, then, immediately after such Repurchase Event Repurchase Date, such Securities will cease to be outstanding and interest and Liquidated Damages Amount, if any, on such Securities will cease to accrue, whether or
not such Securities are delivered to the Paying Agent, and the rights of the Holders in respect thereof shall terminate (other than the right to receive the Repurchase Event Repurchase Price upon delivery of such Securities). 
  
 Section 5.5. Securities Repurchased in Part. 
  
 Any Certificated Security which is to be repurchased only in part shall be
surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such
Holder’s attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without charge, a new Security or Securities, of any authorized denomination as requested
by such Holder in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Security so surrendered which is not repurchased. 
  
 Section 5.6. Covenant to Comply With Securities Laws Upon Repurchase of Securities. 
  
 When complying with the provisions of Section 5.1 hereof (provided that such
offer or purchase constitutes an “issuer tender offer” for purposes of Rule 13e-4 (which term, as used herein, includes any successor provision thereto) under the Exchange Act at the time of such offer or purchase), and subject to any
exemptions available under applicable law, the Company shall: 
  
 (a) comply with Rule 13e- 4 and Rule 14e-1 (or any successor provision) under the Exchange Act; 
  
 (b) file the related Schedule TO (or any successor schedule, form or report) under the Exchange Act; and 
  

 37 

 (c) otherwise comply with all federal and state securities laws so as to permit the rights and
obligations under this Article V to be exercised in the time and in the manner specified therein. 
  
 To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Article V, the Company’s compliance with
such laws and regulations shall not in and of itself cause a breach of its obligations under this Article V. 
  
 Section 5.7. Repayment to the Company. 
  
 To the extent that the aggregate amount of Cash deposited by the Company pursuant to Section 5.4 exceeds the aggregate Repurchase Event Repurchase Price
of the Securities or portions thereof which the Company is obligated to repurchase as of the Repurchase Event Repurchase Date then, promptly after the Repurchase Event Repurchase Date, the Paying Agent shall return any such excess to the Company.

  
 ARTICLE VI 
  
 COVENANTS 
  
 Section 6.1. Payment of Securities. 
  
 The Company shall promptly make all payments in respect of the Securities on the dates and in the manner provided in the
Securities or pursuant to this Indenture. Principal amount, Redemption Price, Repurchase Price and Repurchase Event Repurchase Price and accrued and unpaid interest and Liquidated Damages Amount, if any, shall be considered paid on the applicable
date due if by 10:00 a.m., New York City time, on such date the Paying Agent holds, in accordance with this Indenture, Cash or securities, if permitted hereunder, sufficient to pay all such amounts then due. The Company shall, to the fullest extent
permitted by law, pay interest on overdue principal and overdue installments of interest and Liquidated Damages Amount, if any, at the rate borne by the Securities per annum. Except as otherwise specified, all references in this Indenture or the
Securities to interest shall be deemed to include, without duplication, Liquidated Damages Amount, if any, payable pursuant to the Registration Rights Agreement. 
  
 Payment of the principal of and interest and Liquidated Damages Amount, if any, on the Securities shall be in Cash.

  
 Except as provided in the immediately succeeding paragraph,
the Company shall pay interest and Liquidated Damages Amount, if any, on the Securities to the Person in whose name the Securities are registered at the close of business on the Regular Record Date next preceding the corresponding Interest Payment
Date. Any such interest and Liquidated Damages Amount, if any, not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may be paid (a) to the Person in whose name the Securities
are registered at the close of business on a Special Record Date for the payment of such defaulted interest and Liquidated Damages Amount, if any, to be fixed by the Trustee, notice whereof will be given to the Holders not less than 10 days prior to
such Special Record 

  

 38 

 
Date or (b) at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be listed,
and upon such notice as may be required by such exchange. 
  
 If a
Security is redeemed pursuant to Article III hereof or the Holder elects to require the Company to repurchase such Security pursuant to either Article IV or Article V hereof on a date that is after the Regular Record Date and prior to the
corresponding Interest Payment Date, interest and Liquidated Damages Amount, if any, accrued and unpaid on such Security to, but not including, the applicable Redemption Date, Repurchase Date or Repurchase Event Repurchase Date will be paid to the
same Holder to whom the Company pays the principal of such Security regardless of whether such Holder was the registered Holder on the Regular Record Date immediately preceding the applicable Redemption Date, Repurchase Date or Repurchase Event
Repurchase Date. 
  
 Holders must surrender the Securities to the
Paying Agent to collect payment of principal. Payment of interest and Liquidated Damages Amount, if any, on Certificated Securities will be made by (i) check mailed to the address of the Person entitled thereto as such address appears in the
Register if such Securities have an aggregate principal amount of $5 million or less or (ii) wire transfer of immediately available funds to an account designated by such Person if such Securities have an aggregate principal amount in excess of $5
million. Notwithstanding the foregoing, so long as the Securities are registered in the name of a Depositary or its nominee, all payments with respect to the Securities shall be made by wire transfer of immediately available funds to the account of
the Depositary or its nominee. 
  
 Section 6.2. SEC and Other
Reports to the Trustee. 
  
 The Company shall ensure delivery
to the Trustee within 15 days after it files such annual and quarterly reports, information, documents and other reports with the SEC, copies of its annual report and of the information, documents and other reports (or copies of such portions of any
of the foregoing as the SEC may by rules and regulations prescribe) which the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act in accordance with TIA Section 314(a); provided, however, that the
Company shall not be required to deliver to the Trustee any material for which the Company has sought and received confidential treatment by the SEC. In the event the Company is at any time no longer subject to the reporting requirements of Section
13 or 15(d) of the Exchange Act, it shall continue to provide the Trustee with annual and quarterly reports containing substantially the same information as would have been required to be filed with the SEC had the Company continued to have been
subject to such reporting requirements. In such event, such reports shall be provided at the times the Company would have been required to provide reports had it continued to have been subject to such reporting requirements. The Company also shall
comply with the other provisions of TIA Section 314(a). Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any
information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

  

 39 

 Section 6.3. Compliance Certificate. 
  
 The Company shall deliver to the Trustee within 120 days after the end of
each fiscal year of the Company (beginning with the fiscal year ending February 29, 2004) an Officers’ Certificate, stating whether or not to the knowledge of the signers thereof, the Company is in Default in the performance and observance of
any of the terms, provisions and conditions of this Indenture and if the Company shall be in Default, specifying all such Defaults and the nature and status thereof of which they may have knowledge. 
  
 Section 6.4. Further Instruments and Acts. 
  
 Upon reasonable request of the Trustee, or as otherwise necessary, the
Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture. 
  
 Section 6.5. Maintenance of Office or Agency of the Trustee, Registrar, Paying Agent and Conversion Agent.

  
 The Company will maintain in the Borough of Manhattan, The
City of New York, an office or agency of the Trustee, Registrar, Paying Agent and Conversion Agent where Securities may be presented or surrendered for payment, where Securities may be surrendered for registration of transfer, exchange, redemption,
repurchase or conversion and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. An office of the Trustee shall initially be such office or agency for all of the aforesaid purposes. The
Company shall give prompt written notice to the Trustee of the location, and of any change in the location, of any such office or agency (other than a change in the location of the office of the Trustee). If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 14.2. 

 
 The Company may also from time to time designate one or more other offices
or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, for such purposes. 
  
 Section 6.6. Delivery of Information Required Under Rule 144A. 
  
 At any time when the Company is not subject to Section 13 or 15(d) of the Exchange Act, upon the request of a Holder or any
beneficial owner of Securities or holder or beneficial owner of shares of Common Stock issued upon conversion thereof, the Company will make available the information required pursuant to Rule 144A(d)(4) under the Securities Act to such Holder or
any beneficial owner of Securities or holder or beneficial owner of shares of Common Stock issued upon conversion thereof, or to a prospective purchaser of any such security designated by any such holder, as the case may be, to the extent required
to permit compliance by such Holder or holder with Rule 144A under the Securities Act in connection 

  

 40 

 
with the resale of any such security; provided, however, that the Company shall not be required to furnish such information in connection with any
request made on or after the date which is two years from the later of the date such security was last acquired from the Company or an “affiliate” (as defined under Rule 144 under the Securities Act) of the Company. Whether a person is a
beneficial owner shall be determined by the Company to the Company’s reasonable satisfaction. 
  
 Section 6.7. Waiver of Stay, Extension or Usury Laws. 
  
 The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law or any usury or other law wherever enacted, now or at any time hereafter in force, which would prohibit or forgive the Company from paying all or any portion of the principal amount,
Redemption Price, Repurchase Price or Repurchase Event Repurchase Price in respect of Securities, or any interest and Liquidated Damages Amount, if any, on such amounts, as contemplated herein, or which may affect the covenants or the performance of
this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the
Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 
  
 Section 6.8. Statement by Officers as to Default. 
  
 The Company shall deliver to the Trustee, as soon as practicable and in any event within five Business Days after the Company becomes aware of the
occurrence of any Default or Event of Default or, an Officers’ Certificate setting forth the details of such Default or Event of Default and the action which the Company proposes to take with respect thereto.

 Section 7.1. When Company May Merge or Transfer Assets. 
  
 The Company shall not consolidate with, merge with or into, or sell, assign,
convey, transfer or lease its properties and assets substantially in their entirety (computed on a consolidated basis) to any Person, unless: 
  
 (a) either (i) the Company is the surviving entity or (ii) the successor or transferee (the “successor corporation”) is a corporation organized

Securities and the Indenture; 
  
 (b) immediately after giving
effect to such transaction, no Event of Default, and no event which, after notice or the passage of time, or both, would become an Event of Default under this Indenture shall exist; and 
  

 41 

 (c) the Company shall have delivered to the Trustee an Officers’ Certificate and, if requested by
the Trustee, an Opinion of Counsel, each stating that such consolidation, merger, conveyance, transfer, sale, lease or other disposition and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture,
comply with this Article VII and that all conditions precedent herein provided for relating to such transaction have been satisfied. 
  
 Section 7.2. Successor Corporation Substituted 
  
 Upon any consolidation with or merger into any corporation, or any conveyance, transfer or lease of the properties and assets of the Company substantially
in their entirety in accordance with Section 7.1, the successor corporation formed by such consolidation or into which the Company is merged or to which such conveyance, transfer or lease is made shall succeed to, and be substituted for, and may
exercise every right and power of, the Company under this Indenture with the same effect as if such successor corporation had been named as the Company herein, and in the case of a conveyance, transfer, or lease of the properties and assets of the
Company substantially in their entirety, the Company shall be irrevocably released from its liabilities as obligor and maker of the Securities and from its obligations under this Indenture.

specified in Section 8.1(h) or (i) occurs and is continuing, the principal amount plus accrued and unpaid interest and Liquidated Damages Amount, 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 not less than 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 if
the rescission would not conflict with any judgment or decree for payment of money under this Indenture or the Debentures and if all existing Events of Default have been cured or waived except nonpayment of the principal amount plus accrued and
unpaid interest and Liquidated Damages Amount, if any, that have become due solely as a result of acceleration and if all amounts due to the Trustee under Section 9.7 have been paid. No such rescission shall affect any subsequent Default or impair
any right consequent thereto. 
  
 Section 8.3. Other
Remedies. 
  
 If an Event of Default occurs and is
continuing, the Trustee may, but shall not be obligated to, pursue any available remedy to collect the payment of the principal amount plus accrued and unpaid interest and Liquidated Damages Amount, 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 8.4. Waiver of Past Defaults. 
  
 Subject to Sections 8.7 and 11.2, the Holders of not less than a majority in
aggregate principal amount of the Securities at the time outstanding, by notice to the Trustee 

  

 44 

 
(and without notice to any other Securityholder), may waive an existing Default (or Event of Default) and its consequences except: 
  
 (a) an Event of Default in the payment of the principal of, or any interest
or Liquidated Damages Amount, if any, with respect to, any Security or the payment of any applicable Repurchase Price, Repurchase Event Repurchase Price or Redemption Price; or 
  
 (b) a Default in respect of any provision of this Indenture or the Securities, which, under Section 11.2, cannot be amended
or modified without the consent of each Securityholder affected thereby. 
  
 When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right. This Section 8.4 shall be in lieu of Section 316(a)1(B) of the TIA and
such Section 316(a)1(B) is hereby expressly excluded from this Indenture, as permitted by the TIA. 
  
 Section 8.5. Control by Majority. 
  
 The Holders of a majority in aggregate principal amount of the Securities at the time outstanding may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines in good
faith is prejudicial to the rights of other Securityholders or would involve the Trustee in personal liability unless the Trustee is offered indemnity or security satisfactory to it. This Section 8.5 shall be in lieu of Section 316(a)1(A) of the TIA
and such Section 316(a)1(A) is hereby expressly excluded from this Indenture, as permitted by the TIA. 
  
 Section 8.6. Limitation on Suits. 
  
 A Securityholder may not pursue any remedy with respect to this Indenture or the Securities unless: 
  
 (a) the Holder gives to the Trustee written notice stating that an Event of
Default is continuing; 
  
 (b) 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; 
  
 (c) such Holder or Holders offer to the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense; 
  
 (d) the Trustee does not comply with the request within 60 days after receipt
of such notice, request and offer of security or indemnity; and 
  
 (e) 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. 
  

 45 

 A Securityholder may not use this Indenture to prejudice the rights of any other Securityholder or to
obtain a preference or priority over any other Securityholder. 
  
 Section 8.7. Rights of Holders to Receive Payment or to Convert. 
  
 Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of the principal amount, Redemption Price, Repurchase Price, Repurchase Event Repurchase Price or interest and
Liquidated Damages Amount, if any, in respect of the Securities held by such Holder, on or after the respective due dates expressed in the Securities and in this Indenture, and to convert such Securities in accordance with Article XII, or to bring
suit for the enforcement of any such payment on or after such respective dates or the right to convert, is absolute and unconditional and shall not be impaired or affected adversely without the consent of such Holder. 
  
 Section 8.8. Collection Suit by Trustee. 
  
 If an Event of Default described in Section 8.1(a) or (b), occurs and is
continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or another obligor on the Securities for the whole amount owing with respect to the Securities and the amounts provided for in
Section 9.7. 
  
 Section 8.9. Trustee May File Proofs of
Claim. 
  
 In case of the pendency of any receivership,
insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal amount, Redemption Price, Repurchase Price, Repurchase Event Repurchase Price or interest and Liquidated Damages Amount, 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 amount
of the principal amount, Redemption Price, Repurchase Price, Repurchase Event Repurchase Price, or interest and Liquidated Damages Amount, 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 9.7) and of the Holders allowed in such
judicial proceeding, and 
  
 (b) to collect and receive any moneys
or other property payable or deliverable on any such claims and to distribute the same; 
  
 and any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall
consent to the making of such payments directly 

  

 46 

 
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 9.7. 
  
 Nothing contained herein shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the
rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
  
 Section 8.10. Priorities. 
  
 (a) If the Trustee collects any money pursuant to this Article VIII, it shall pay out the money in the following order: 
  
 FIRST: to the Trustee for amounts due under Section 9.7;

  
 SECOND: to Securityholders for amounts due
and unpaid on the Securities for the principal amount, Redemption Price, Repurchase Price, Repurchase Event Repurchase Price or interest and Liquidated Damages Amount, 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 8.10. 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 8.11. 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 8.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 8.7 or a suit by Holders of more than
10% in aggregate principal amount of the Securities at the time outstanding. This Section 8.11 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 8.12. Restoration of Rights and Remedies.

  
 If the Trustee or any Holder has instituted any proceedings
to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every 

  

 47 

 
case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former
positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 
  
 ARTICLE IX 
  
 TRUSTEE 
  
 Section 9.1. Duties of Trustee. 
  
 (a) If an
Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise of those rights and powers 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: 
  
 (i) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied
covenants or obligations shall be read into this Indenture against the Trustee; and 
  
 (ii) 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 examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture, but need not confirm or investigate the accuracy of mathematical calculations or
other facts stated therein. 
  
 This Section 9.1(b) shall be in lieu of Section
315(a) of the TIA and such Section 315(a) is hereby expressly excluded from this Indenture, as permitted by the TIA. 
  
 (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: 
  
 (i) this Section (c) does not limit the
effect of Section (b) of this Section 9.1; 
  
 (ii) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and

respectively, and such Sections 315(d)(1), 315(d)(2) and 315(d)(3) are hereby expressly excluded from this Indenture, as permitted by the TIA. 
  
 (d) Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b), (c) and (e) of this Section 9.1.

 (f) Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the 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. 
  
 Section 9.2. Rights of Trustee. 
  
 Subject to its duties and responsibilities under Section 9.1 and under the
TIA, 
  
 (a) the Trustee may conclusively rely and shall be
protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document
believed by it to be genuine and to have been signed or presented by the proper party or parties; 
  
 (b) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering
or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, conclusively rely upon an Officers’ Certificate;

 (f) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of

security or indemnity satisfactory to it against the costs, expenses and liabilities which may be incurred therein or thereby; 
  
 (g) any request or direction of the Company mentioned herein shall be

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

  
 (k) the Trustee may request that the Company deliver an
Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may be signed by any person authorized to sign
an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded. 
  
 Section 9.3. Individual Rights of Trustee. 
  
 The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its
Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, Conversion Agent or co-registrar may do the same with like rights. However, the Trustee must comply with Sections 9.10 and 9.11. 
  
 Section 9.4. Trustee’s Disclaimer. 
  
 The Trustee makes no representation as to the validity or adequacy of this
Indenture or the Securities, it shall not be accountable for the Company’s use or application of the proceeds from the Securities, it shall not be responsible for any statement in any registration 

  

 50 

 
statement for the Securities under the Securities Act or in any offering document for the Securities, this Indenture or the Securities (other than its
certificate of authentication), or the determination as to which beneficial owners are entitled to receive any notices hereunder. 
  
 Section 9.5. Notice of Defaults. 
  
 If a Default occurs and if it is known to the Trustee, the Trustee shall give to each Securityholder notice of the Default within 90 days after it occurs
or, if later, within 15 days after it is known to the Trustee, unless such Default shall have been cured or waived before the giving of such notice. Notwithstanding the preceding sentence, except in the case of a Default described in Section 8.1(a)
or (b), the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interest of the Securityholders. The preceding sentence shall be in lieu of the
proviso to Section 315(b) of the TIA and such proviso is hereby expressly excluded from this Indenture, as permitted by the TIA. 
  
 Section 9.6. Reports by Trustee to Holders. 
  
 Within 60 days after each May 15 beginning with the May 15 following the date of this Indenture, the Trustee shall mail to each Securityholder a brief
report dated as of such May 15 that complies with TIA Section 313(a), if required by such Section 313(a). The Trustee also shall comply with TIA Section 313(b). The Trustee will also transmit by mail all reports as required by TIA Section 313(c).

  
 The Company agrees to notify the Trustee promptly whenever the
Securities become listed on any securities exchange and of any delisting thereof. 
  
 Section 9.7. Compensation and Indemnity. 
  
 The Company agrees to: 
  
 (a) 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) reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable
compensation and the expenses, advances and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its own negligence or willful misconduct or bad faith; and 
  
 (c) fully indemnify the Trustee, any predecessor Trustee and each of their
directors and officers for, and to hold each of them harmless against, any and all 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 or willful misconduct or bad faith on the part of the Person so indemnified, 

  

 51 

 
arising out of or in connection with the acceptance or administration of this trust, including the reasonable costs and expenses of defending 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 powers or duties hereunder, or in connection with enforcing the provisions of this Section 9.7. 

 
 The Trustee shall notify the Company promptly of any claim for which it
may seek indemnity hereunder; provided, that a failure to notify shall not relieve the Company of its obligations hereunder except to the extent the Company is materially prejudiced by such failure. The Trustee shall have the right to employ
one separate counsel in any such action or proceeding and participate in the investigation and defense thereof, and the Company shall pay the reasonable fees and expenses of such separate counsel; provided, however, that the Trustee may only
employ such separate counsel at the expense of the Company if in the reasonable judgment of the outside counsel to the Trustee (i) a conflict of interest exists by reason of common representation or (ii) there are legal defenses available to the
Trustee that are different from or are in addition to those available to the Company or if all parties commonly represented do not agree as to the action (or inaction) of counsel. 
  
 To secure the Company’s payment obligations in this Section 9.7, the Trustee shall have a lien prior to the Securities
on all money or property held or collected by the Trustee, except that held in trust to pay the principal amount, Redemption Price, Repurchase Price, Repurchase Event Repurchase Price or interest and Liquidated Damages Amount, if any, as the case
may be, on particular Securities. 
  
 The Company’s payment
obligations pursuant to this Section 9.7 shall survive the discharge of this Indenture and the resignation or removal of the Trustee. When the Trustee incurs expenses after the occurrence of a Default specified in Section 8.1(h) or (i), the expenses
including the reasonable charges and expenses of its counsel, are intended to constitute expenses of administration under any Bankruptcy Law. 
  
 Section 9.8. Replacement of Trustee. 
  
 The Trustee may resign by so notifying the Company; provided, however, that no such resignation shall be effective until a successor Trustee has
accepted its appointment pursuant to this Section 9.8. The Holders of a majority in aggregate principal amount of the Securities at the time outstanding may remove the Trustee by so notifying the Trustee and the Company. The Company as soon as
practicable shall remove the Trustee if: 
  
 (a) the Company
becomes aware that the Trustee fails to comply with Section 9.10; 
  
 (b) the Trustee is adjudged bankrupt or insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; 
  
 (c) a receiver or public officer takes charge of the Trustee or its property; or 
  
 (d) the Trustee otherwise becomes incapable of acting. 
  

 52 

 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 9.7. 
  
 If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring
Trustee, the Company or the Holders of a majority in aggregate principal amount of the Securities at the time outstanding may petition at the expense of the Company 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 9.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
  
 Section 9.9. Successor Trustee by Merger. 
  
 If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust
business or assets to, another corporation or company, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee. 
  
 Section 9.10. Eligibility; Disqualification. 
  
 The Trustee shall at all times satisfy the requirements of TIA Sections 310(a)(1) and 310(b). The Trustee (or its parent
holding company) shall have a combined capital and surplus of at least $100,000,000 as set forth in its most recent published annual report of condition. Nothing contained herein shall prevent the Trustee from filing with the Commission the
application referred to in the penultimate paragraph of TIA Section 310(b). 
  
 Section 9.11. 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.

DISCHARGE OF INDENTURE 
  
 Section 10.1. Discharge of Liability on Securities.

cancellation or (b) all outstanding Securities have become due and payable (whether at the Stated Maturity or upon acceleration, or on any Redemption Date, or with respect to any Repurchase Date or Repurchase Event Repurchase Date, or upon
conversion) and the Company deposits with the Paying Agent or Conversion Agent Cash, Common Stock or Applicable Stock, as applicable, sufficient to pay all amounts due and owing on all outstanding Securities (other than Securities replaced pursuant
to Section 2.7), and if in either case the Company pays all other sums payable hereunder by the Company, then this Indenture shall, subject to Section 9.7, cease to be of further effect. The Trustee shall join in the execution of a document prepared

 The Trustee and the Paying Agent shall return to the Company upon written

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 Cash or securities for that period commencing after the return thereof.

 Except as provided below in this Section 11.2, this Indenture or the

 (l) modify any of (a)-(k) above. 
  
 It shall not be necessary for the consent of the Holders under this Section 11.2 to approve the particular form of any proposed amendment, but it shall be
sufficient if such consent approves the substance thereof. 
  
 After an amendment under this Section 11.2 becomes effective, the Company shall mail to each Holder a notice briefly describing the amendment. 
  
 Nothing contained in this Section 11.2 shall impair the ability of the Company and the Trustee to amend this Indenture or the Securities without the

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 11.5. Notation on or Exchange of Securities.

Securities. 
  

 57 

 Section 11.6. Trustee to Sign Supplemental Indentures.

Trustee shall receive, and (subject to the provisions of Section 9.1) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture.

  
 Section 11.7. Effect of Supplemental Indentures.

  
 Upon the execution of any supplemental indenture under this

 ARTICLE XII 
  
 CONVERSION 
  
 Section 12.1. Conversion Privilege. 
  
 (a) Subject to and upon compliance with the provisions of this Article XII,
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 or a multiple of $1,000) of such Security into shares of Common Stock at the Conversion Rate in effect
on the Conversion Date only as follows: 
  
 (i)
during any fiscal quarter (beginning with the quarter ending May 31, 2004) if the Sale Price of the Common Stock for at least 20 consecutive Trading Days in the Measurement Period during the immediately preceding fiscal quarter exceeds 120% of the
Conversion Price in effect on the last Trading Day of such Measurement Period (in the event that the Conversion Price on such last Trading Day of such Measurement Period is not the same as the Conversion Price in effect for each of the Trading Days
in such Measurement Period, the Company shall make such adjustments as it, in its discretion, deems appropriate in determining whether the foregoing condition has been met); 
  
 (ii) during any five consecutive Trading Day period immediately following any five consecutive Trading Day
period (the “Debenture Measurement Period”) in which the average Market Price per $1,000 principal amount of Securities during such Debenture Measurement Period was less than 97% of the average Conversion Value during such Debenture
Measurement Period; provided, however, that a Holder shall not have the right to convert any Security pursuant to this Section 12.1(a)(ii) after January 15, 2019 if on any Trading Day during such Debenture Measurement Period the Sale Price
was greater than the then-current Conversion Price but less than 120% of the then-current Conversion Price; 
  

 58 

 (iii) at any time prior to 5:00 p.m., New York City time, on the Business Day immediately
preceding the Redemption Date, if such Security has been called for redemption pursuant to Article III hereof; or 
  
 (iv) as provided in Section 12.1(b). 
  
 The Company shall, determine at the end of each applicable period whether the Securities shall be convertible as a result of the occurrence of an event
specified in clause (a) or (b) above and, if the Securities shall be so convertible, the Company shall promptly deliver to the Trustee written notice thereof. Whenever the Securities shall become convertible pursuant to this Section 12.1, the
Company or, at the Company’s request, the Trustee in the name and at the expense of the Company, shall notify the Holders in writing of the event triggering such convertibility in the manner provided in Section 14.2, and the Company shall also
publicly announce such information and publish it on the Company’s website. Any notice so given shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. 
  
 (b) In addition, in the event that: 
  
 (i) 
  
 (A) the Company distributes to all holders of Common Stock
rights or warrants (other than pursuant to a stockholder rights plan) entitling them to purchase Common Stock at less than the Sale Price of the Common Stock at the time of the distribution of the rights or warrants; or 
  
 (B) the Company distributes to all holders of Common Stock
cash or other assets, debt securities or certain rights to purchase the Company’s securities, which distribution has a per share value as determined by the Board of Directors of the Company exceeding 15% of the Sale Price of the Common Stock on
the Business Day immediately preceding the declaration for such distribution; 
  
 then, in each case, the Company must notify, in writing, Holders of Securities of the occurrence of such an event at least 20 days prior to the Ex-Dividend Date for any such distribution. Once the Company has given
such notice, Holders may surrender their Securities for conversion at any time until the earlier of the close of business on the Business Day immediately preceding the Ex-Dividend Date or the date of announcement by the Company that the distribution
will not take place. No Holder may convert its Securities pursuant to this Section 12.1(b) if such Holder may participate in the distribution without conversion. 
  
 (ii) the Company becomes party to a consolidation, merger or binding share exchange pursuant to which the
Common Stock of the Company would be converted into cash, securities or other property, a Holder may surrender the Securities for conversion at any time from and after the date which is 15 days prior to the anticipated effective date of the
transaction until 15 days after the actual date of the transaction. If the Company becomes party to a consolidation, merger or binding share 

  

 59 

 
exchange pursuant to which the Common Stock of the Company would be converted into cash, securities or other property, then at the effective time of the
transaction, the right to convert the Securities into Common Stock shall be changed into a right to convert such Securities into the kind and amount of cash, securities or other property which the Holder would have received if the Holder had
converted such Securities immediately prior to the transaction. If the transaction constitutes a Repurchase Event, the Holder shall have the rights set forth in Article V above. 
  
 (iii) any “person” or “group” (as such terms are used for purposes of Sections 13(d) and
14(d) of the Exchange Act) becomes the “beneficial owner” (as such term is used in Rule 13-d-3 under the Exchange Act), directly or indirectly, of 50% or more of the total voting power of all classes of the Company’s capital stock
entitled to vote generally in the election of directors, a holder may surrender the Securities for conversion at any time from and after the date that is 15 days prior to the anticipated effective date of the transaction or event until 15 days after
the actual date of such transaction or event. If the transaction constitutes a Repurchase Event, the Holder shall have the rights set forth in Article V above. 
  

Section 12.2. Conversion Procedure; Conversion Rate; Fractional Shares. 
  
 (a) Each Security shall be convertible at the office of the Conversion Agent into fully paid and nonassessable shares
(calculated to the nearest 1/100th of a share) of Common Stock. The Security will be converted into shares of Common Stock at the Conversion Rate therefore. 
  
 No payment or adjustment shall be made in respect of dividends on the Common Stock or accrued interest (but not accrued and unpaid Liquidated Damages
Amount, if any) on a converted Security, except as described in Section 12.9 hereof. In accordance with Section 2(e) of the Registration Rights Agreement, any accrued but unpaid Liquidated Damages Amount with respect to a Security delivered for
conversion to but not including the Conversion Date shall be paid to the Notice Holder (as defined in the Registration Rights Agreement) who delivered such Security for conversion on or promptly following 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 12.3(g) hereof, make a Cash payment (calculated to the nearest cent) equal to such fraction multiplied by the Sale Price of the Common Stock on the last Trading Day
prior to the date of conversion. 
  
 Notwithstanding the
foregoing, a Security in respect of which a Holder has delivered a Repurchase Notice or Repurchase Event Repurchase Notice exercising such Holder’s option to require the Company to repurchase such Security may be converted only if such notice
of exercise is withdrawn in accordance with Sections 4.3 or 5.3 hereof, as the case may be, prior to the close of business on the Business Day immediately preceding the applicable Repurchase Date or Repurchase Event Repurchase Date, as the case may
be. 
  

 60 

 (b) Before any Holder of a Security shall be entitled to convert the same into Common Stock, such Holder
shall, in the case of Securities issued in global form, comply with the procedures of the Depositary in effect at that time, and in the case of certificated Securities, surrender such Securities, duly endorsed to the Company or in blank, at the
office of the Conversion Agent, and shall give written notice to the Company at said office or place in the form of the Conversion Notice attached to the Security (the “Conversion Notice”) that such Holder elects to convert the same
and shall state in writing therein the principal amount of Security to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for Common Stock to be issued. 
  
 Before any such conversion, a Holder also shall pay all funds required, if
any, relating to interest on the Securities, as provided in Section 12.9, and all taxes or duties, if any, as provided in Section 12.8. 
  
 If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares of Common Stock which shall be
deliverable upon conversion shall be computed on the basis of the aggregate principal amount of the Security (or specified portions thereof to the extent permitted thereby) so surrendered. 
  
 If shares of Common Stock to be issued upon conversion of a Restricted
Security are to be issued in the name of a Person other than the Holder of such Restricted Security, such Holder must deliver to the Conversion Agent a certification in substantially the form set forth in a Transfer Certificate dated the date of
surrender of such Restricted Security and signed by such Holder, as to compliance with the restrictions on transfer applicable to such Restricted Security. The Company shall not be required to issue Common Stock upon conversion of any such
Restricted Security to a Person other than the Holder if such Restricted Security is not so accompanied by a properly completed certification, and the Registrar shall not be required to register Common Stock upon conversion of any such Restricted
Security in the name of a Person other than the Holder if such Restricted Security is not so accompanied by a properly completed certification. 
  
 (c) A Security shall be deemed to have been converted as of the close of business on the date of the surrender of such Security for conversion as provided
above (such date, the “Conversion Date” for such Security), and the person or persons entitled to receive any Common Stock issuable upon such conversion shall be treated for all purposes as the record Holder or Holders of such
Common Stock as of the close of business on such date. Upon conversion, all obligations under the Securities so converted will be deemed satisfied, including with respect to any accrued and unpaid interest, but not with respect to accrued and unpaid
Liquidated Damages Amount, if any, which shall be paid upon conversion in accordance with this Section 12.2. 
  
 (d) Delivery of Common Stock and Cash in respect of accrued and unpaid Liquidated Damages Amount, if any, to a Holder of a Security upon conversion of
such Security shall be accomplished by delivery to the Conversion Agent of certificates for the relevant number of shares, other than in the case of Holders of Common Stock in book-entry form with the Depository, which shares will be delivered in
accordance with the Depository’s customary 

  

 61 

 
practices and delivery of Cash in respect of Liquidated Damages Amount, if any, to the Conversion Agent or the Depository, as applicable, for payment to the
Holder. 
  
 (e) In case any Certificated 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 12.8 hereof), a new Security or Securities in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Certificated Securities. 
  
 (f) If a holder exercises its right to require the Company to repurchase the
Securities as described in Article IV or Article V, such Holder may convert its Securities as provided above only if it withdraws its applicable Repurchase Notice or Repurchase Event Repurchase Notice and converts its Securities prior to the close
of business on the business day immediately preceding the applicable Repurchase Date. 
  
 Section 12.3. Adjustment of Conversion Rate. 
  
 The Conversion Rate shall be adjusted from time to time as follows: 
  
 (a) In case the Company shall, at any time or from time to time while any of the Securities are outstanding, pay a dividend or make a distribution in
shares of Common Stock to all holders of its outstanding shares of Common Stock, then the Conversion Rate in effect at the opening of business on the date next following the Record Date fixed for the determination of stockholders entitled to receive
such dividend or other distribution shall be increased by multiplying such Conversion Rate by a fraction: 
  
 (i) the numerator of which shall be the sum of the number of shares of Common Stock outstanding at the close of business on such Record
Date fixed for such determination and the total number of shares constituting such dividend or other distribution; and 
  
 (ii) the denominator of which shall be the number of shares of Common Stock outstanding at the close of business on such Record Date fixed
for such determination. 
  
 Such increase shall become effective
immediately after the opening of business on the day following the Record Date fixed for such determination. 
  
 If any dividend or distribution of the type described in this Section 12.3(a) is declared but not so paid or made, the Conversion Rate shall again be
adjusted to the Conversion Rate which would then be in effect if such dividend or distribution had not been declared. 
  
 (b) In case the Company shall, at any time or from time to time while any of the Securities are outstanding, subdivide its outstanding shares of Common
Stock into a greater number of shares of Common Stock, then the Conversion Rate in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be 

  

 62 

 
proportionately increased, and conversely, in case the Company shall, at any time or from time to time while any of the Securities are outstanding, combine
its outstanding shares of Common Stock into a smaller number of shares of Common Stock, then the Conversion Rate in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately
decreased. In each such case, the Conversion Rate shall be adjusted by multiplying such Conversion Rate by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately after giving effect to such
subdivision or combination and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such subdivision or combination. Such increase or reduction, as the case may be, shall become effective
immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective. 
  
 (c) In case the Company shall, at any time or from time to time while any of the Securities are outstanding, issue rights or warrants (other than pursuant
to a shareholders rights plan) exercisable for a period less than or equal to 60 days (other than any rights or warrants referred to in Section 12.3(d)), to all holders of its shares of Common Stock entitling them to subscribe for or purchase shares
of Common Stock (or securities convertible into or exchangeable or exercisable for shares of Common Stock), at a price per share (or having a conversion, exchange or exercise price per share) less than the Sale Price of the Common Stock on the
Trading Day immediately preceding the date of the announcement of such issuance (treating the conversion, exchange or exercise price per share of the securities convertible into or exchangeable or exercisable for Common Stock as equal to the
quotient of (x) the sum of (i) the price for a unit of the security convertible into or exchangeable or exercisable for Common Stock and (ii) any additional consideration initially payable upon the conversion, exchange or exercise of such security
into Common Stock divided by (y) the number of shares of Common Stock initially underlying such convertible, exchangeable or exercisable security), then the Conversion Rate shall be adjusted so that the same shall equal the rate determined by
multiplying the Conversion Rate in effect at the opening of business on the date after such date of announcement by a fraction: 
  
 (i) the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the date of announcement,
plus the total number of additional shares of Common Stock so offered for subscription or purchase (or into which the convertible, exchangeable or exercisable securities so offered are convertible, exchangeable or exercisable); and 
  
 (ii) the denominator of which shall be the number of shares
of Common Stock outstanding on the close of business on the date of announcement, plus the number of shares (or convertible, exchangeable or exercisable securities) which the aggregate offering price of the total number of shares (or convertible,
exchangeable or exercisable securities) so offered for subscription or purchase (or the aggregate conversion, exchange or exercise price of the convertible securities so offered) would purchase at the Sale Price of the Common Stock on the Business
Day immediately preceding the date of the announcement of such issuance (determined by multiplying 

  

 63 

 
such total number of shares so offered by the exercise price of such rights or warrants and dividing the product so obtained by such Sale Price). 

 
 Such adjustment shall become effective immediately after
the opening of business on the day following the date of announcement of such issuance. 
  
 To the extent that shares of Common Stock (or securities convertible into or exchangeable or exercisable for shares of Common Stock) are
not delivered pursuant to such rights or warrants, upon the expiration or termination of such rights or warrants, the Conversion Rate shall be readjusted to the Conversion Rate which would then be in effect had the adjustments made upon the issuance
of such rights or warrants been made on the basis of the delivery of only the number of shares of Common Stock (or securities convertible into or exchangeable or exercisable for shares of Common Stock) actually delivered. In the event that such
rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if the date fixed for the determination of stockholders entitled to receive such rights or warrants had not
been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Sale Price, and in determining the aggregate offering price of such shares of Common Stock, there
shall be taken into account any consideration received for such rights or warrants and the value of such consideration if other than Cash, to be determined in good faith by the Board of Directors of the Company. 
  
 (d) (i) In case the Company shall, at any time or from time to time while any
of the Securities are outstanding, by dividend or otherwise, distribute to all holders of its shares of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing
corporation and the Common Stock is not changed or exchanged), shares of its Capital Stock (other than any dividends or distributions to which Section 12.3(a) applies), evidences of its Indebtedness or other non-Cash assets, including securities,
but excluding (x) any rights or warrants referred to in Section 12.3(c), (y) dividends or distributions of stock referred to in Section 12.3(a) and (z) dividends and distributions paid exclusively in Cash (such capital stock, evidence of its
indebtedness, other non-Cash assets or securities being distributed hereinafter in this Section 12.3(d) called the “distributed assets”), then, in each such case, subject to the other provisions of this Section 12.3(d), the
Conversion Rate shall be increased so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect immediately prior to the close of business on the Record Date with respect to such distribution by a fraction:

  
 (A) the numerator of which shall be the
Current Market Price; and 
  
 (B) the denominator
of which shall be such Current Market Price, less the Fair Market Value on such date of the portion of the distributed assets so distributed applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock
outstanding on the Record Date) (determined as provided in Section 12.3(f)). 
  

 64 

 Such increase shall become effective immediately prior to the opening of business on the day following
the Record Date for such distribution. In the event that such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such dividend or distribution had
not been declared. 
  
 (ii) If the Board of
Directors determines the Fair Market Value of any distribution for purposes of this Section 12.3(d) by reference to the actual or when issued trading market for any distributed assets comprising all or part of such distribution, it must in doing so
consider the prices in such market over the same period (the “Reference Period”) used in computing the Current Market Price pursuant to Section 12.3(f) to the extent possible, unless the Board of Directors determines in good faith
that determining the Fair Market Value during the Reference Period would not be in the best interest of the Holders. 
  
 (iii) In the event any such distribution consists of shares of capital stock of, or similar equity interests in, one or more of the
Company’s Subsidiaries (a “Spin-Off”), the Fair Market Value of the securities to be distributed shall equal the average of the closing sale prices of such securities on the principal securities market on which such securities
are traded for the ten consecutive Trading Days commencing on and including the sixth Trading Day of those securities after the effectiveness of the Spin-Off, and the Current Market Price shall be measured for the same period. In the event, however,
that an underwritten initial public offering of the securities in the Spin-Off occurs simultaneously with the Spin-Off, Fair Market Value of the securities distributed in the Spin-Off shall mean the initial public offering price of such securities
and the Current Market Price shall mean the Sale Price for the Common Stock on the same Trading Day. 
  
 (iv) Rights or warrants distributed by the Company to all holders of its shares of Common Stock entitling them to subscribe for or
purchase shares of the Company’s Capital Stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”), (x) are deemed to be transferred
with such shares of Common Stock, (y) are not exercisable and (z) are also issued in respect of future issuances of shares of Common Stock shall be deemed not to have been distributed for purposes of this Section 12.3(d) (and no adjustment to the
Conversion Rate under this Section 12.3(d) will be required) until the occurrence of the earliest Trigger Event. If such right or warrant is subject to subsequent events, upon the occurrence of which such right or warrant shall become exercisable to
purchase different distributed assets, evidences of indebtedness or other assets, or entitle the holder to purchase a different number or amount of the foregoing or to purchase any of the foregoing at a different purchase price, then the occurrence
of each such event shall be deemed to be the date of issuance and record date with respect to a new right or warrant (and a termination or expiration of the existing right or warrant without exercise by the holder thereof). Pursuant to rights issued
under any Company shareholder’s rights plan, if holders of the Securities exercising the right of conversion after the date the rights separate from the underlying Common Stock are not entitled to receive the rights that would otherwise be
attributable to the shares of Common Stock received upon 

  

 65 

 
conversion, the Conversion Rate will be adjusted as though the rights were being distributed to holders of Common Stock on the date of such separation. If
such an adjustment is made and the rights are later redeemed, invalidated or terminated, then a corresponding reversing adjustment will be made to the conversion rate on an equitable basis. 
  
 In addition, in the event of any distribution (or deemed
distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding paragraph) with respect thereto, that resulted in an adjustment to the Conversion Rate under this Section 12.3(d): 
  
 (A) in the case of any such rights or warrants which shall
all have been redeemed or repurchased without exercise by any holders thereof, the Conversion 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 of shares of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders
of shares of Common Stock as of the date of such redemption or repurchase; and 
  
 (B) in the case of such rights or warrants which shall have expired or been terminated without exercise, the Conversion Rate shall be
readjusted as if such rights and warrants had never been issued. 
  
 (v) For purposes of this Section 12.3(d) and Sections 12.3(a), 12.3(b) and 12.3(c), any dividend or distribution to which this Section 12.3(d) is applicable that also includes (x) shares of Common Stock, (y) a
subdivision or combination of shares of Common Stock to which Section 12.3(b) applies or (z) rights or warrants to subscribe for or purchase shares of Common Stock or securities convertible into or exercisable or exchangeable for Common Stock to
which Section 12.3(c) applies (or any combination thereof), shall be deemed instead to be: 
  
 (A) a dividend or distribution of the evidences of indebtedness, assets, shares of capital stock, rights or warrants, other than such
shares of Common Stock, such subdivision or combination or such rights or warrants or securities convertible into or exercisable or exchangeable for Common Stock to which Sections 12.3(a), 12.3(b) and 12.3(c) apply, respectively (and any Conversion
Rate increase required by this Section 12.3(d) with respect to such dividend or distribution shall then be made), immediately followed by 
  

 66 

 (B) a dividend or distribution of such shares of Common Stock, such subdivision or
combination or such rights or warrants or securities convertible into or exercisable or exchangeable for Common Stock (and any further Conversion Rate increase required by Sections 12.3(a), 12.3(b) and 12.3(c) with respect to such dividend or
distribution shall then be made), except: 
  
 (1) the Record Date of such dividend or distribution shall be substituted as (x) “the date fixed for the determination of stockholders entitled to receive such dividend or other distribution,” “Record Date fixed for such
determinations” and “Record Date” within the meaning of Section 12.3(a), (y) “the day upon which such subdivision becomes effective” and “the day upon which such combination becomes effective” within the meaning of
Section 12.3(b), and (z) as “the date fixed for the determination of stockholders entitled to receive such rights or warrants,” “the Record Date fixed for the determination of the stockholders entitled to receive such rights or
warrants” and such “Record Date” within the meaning of Section 12.3(c); and 
  
 (2) 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 12.3(a) and any reduction or increase in the number of shares of Common Stock resulting from such subdivision or combination shall be disregarded in connection with such
dividend or distribution. 
  
 (e) (i) In case the Company shall,
by dividend or otherwise, at any time any Securities are outstanding distribute (a “Triggering Distribution”) to all or substantially all holders of its Common Stock Cash, the Conversion Rate shall be increased so that the same
shall equal the rate determined by multiplying such Conversion Rate in effect on the Record Date for such Triggering Distribution by a fraction of which the numerator shall be the Current Market Price per share of the Common Stock on the Record
Date, and the denominator shall be the Current Market Price per share of the Common Stock on the Record Date less the aggregate amount of cash so distributed applicable to one share of Common Stock (determined on the basis of the number of shares of
Common Stock outstanding on the Record Date), such increase to become effective immediately prior to the opening of business on the day following the date on which the Triggering Distribution is paid. It is expressly understood that a stock buyback,
repurchase or similar transaction or program shall in no event be considered a Triggering Distribution for purposes of this Section 12.3(e)(i). 
  
 (ii) In case the Company or any of its Subsidiaries shall, at any time or from time to time while any of the Securities are outstanding,
make any tender offer or exchange offer for all or any portion of the shares of Common Stock for Cash or other consideration, to the extent that the aggregate amount of Cash and the Fair Market Value, as of the last date on which tenders or
exchanges may be made pursuant to such tender offer or exchange offer, of any other consideration paid in respect of such tender offer or exchange offer (determined on a per share basis) exceeds the Closing Sale Price per share of Common Stock on
the trading day next succeeding the last date on which tenders or exchange may be made pursuant to such tender or exchange offer then the Conversion Rate shall be adjusted such that immediately after the close of business on the date an Excess
Amount Per Share is paid or distributed, 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
payment by a fraction: 
  
 (A) the numerator of
which shall be equal to the Current Market Price on the Record Date; and 
  

 67 

 (B) the denominator of which shall be equal to the Current Market Price on such date
minus such Excess Amount Per Share. 
  
 (iii) In case someone other than the Company or one of its Subsidiaries makes a payment of Cash or other consideration in respect of a tender offer or exchange offer in which: 
  
 (A) as of the closing date of the offer, the Company’s Board of Directors is not recommending rejection
of the offer; 
  
 (B) the tender offer or
exchange offer is for an amount that increases the offeror’s ownership of the Company’s Common Stock to more than 10% of the total shares of Common Stock outstanding; and 
  
 (C) the aggregate amount of such Cash and the Fair Market Value, as of the expiration of such tender offer
or exchange offer, of any such other consideration paid in respect of such tender offer or exchange offer (determined on a per share basis) exceeds the closing Sale Price per share of the Common Stock on the trading day next succeeding the last date
on which tenders or exchanges may be made pursuant to such tender or exchange offer; 
  
 the Conversion Rate shall be adjusted such that immediately after the close of business on the date an Excess Amount Per Share is paid or distributed, 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 payment by a fraction: 
  
 (1) the numerator of which shall be equal to the Current Market Price on the Record Date; and 
  
 (2) the denominator of which shall be equal to the Current
Market Price on such date minus such Excess Amount Per Share. 
  
 Provided, however, no adjustment will be made if as of the closing date of such offer, the offering documents disclose a plan or an intention to cause the Company to engage in a consolidation or merger or sale of substantially all of the
Company’s assets, the offeror accepts the tender of at lease 50% of the outstanding Common Stock at the expiration of the offer, and such merger, consolidation or asset sale is completed within 120 days of the expiration of such tender offer or
exchange offer, and provided that if the merger, consolidation or asset sale is not completed by such time, the conversion rate will be adjusted, retroactive to the date the tender offer or exchange offer expired. 
  

 68 

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

 
 (i) “Current Market Price” on any date
means the average of the daily Sale Prices per share of Common Stock for the ten consecutive Trading Days immediately prior to such date; provided, however, that if the “ex” date (as hereinafter defined) for any event (other than
the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Rate pursuant to Section 12.3(a), (b), (c), (d) or (e) occurs during such ten consecutive Trading Days, “Current Market Price”
shall be calculated for such period in a manner determined conclusively in good faith by the Board of Directors to reflect the impact of such event on the Closing Price of the Common Stock during such period. 
  
 For purposes of this paragraph, the term “ex” date, when used:

  
 (x) with respect to any issuance or
distribution, means the first date on which the shares of Common Stock trade regular way on the relevant exchange or in the relevant market from which the Sale Price was obtained without the right to receive such issuance or distribution;

  
 (y) with respect to any subdivision or
combination of shares of Common Stock, means the first date on which the shares of Common Stock trade regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective; and 
  
 (z) with respect to any tender or exchange offer, means the
first date on which the shares of Common Stock trade regular way on such exchange or in such market after the expiration of such offer. 
  
 Notwithstanding the foregoing, whenever successive adjustments to the Conversion Rate are called for pursuant to this Section 12.3, such adjustments shall
be made to the Current Market Price as may be necessary or appropriate to effectuate the intent of this Section 12.3 and to avoid unjust or inequitable results as determined in good faith by the Board of Directors. 
  
 (ii) “Excess Amount Per Share” shall mean,
with respect to Section 12.3(e)(ii) or (iii), the extent that the aggregate amount of Cash and the Fair Market Value, as of the expiration of any tender offer or exchange offer, of any other consideration paid in respect of such tender offer or
exchange offer (determined on a per share basis) exceeds the Closing Sale Price per share of Common Stock on the trading day next succeeding the last date on which tenders or exchange may be made pursuant to such tender or exchange offer.

  
 (iii) “Fair Market Value”
shall mean the amount which a willing buyer would pay a willing seller in an arm’s length transaction (as determined in good faith by the Board of Directors, whose good faith determination shall be conclusive). 
  

 69 

 (iv) “Record Date” shall mean (except as expressly provided elsewhere in
this Section 12.3): 
  
 (w) with respect to
Section 12.3(a), the date fixed for determination of stockholders entitled to receive the Common Stock issued in such dividend or distribution; 
  
 (x) with respect to Section 12.3(d), the date fixed for determination of stockholders entitled to receive the distributed assets;

  
 (y) with respect to Section 12.3(e)(i), the
date fixed for determination of stockholders entitled to receive the Cash paid in such dividend or distribution; and 
  
 (z) with respect to Sections 12.3(e)(ii) and (iii), the last date on which tenders or exchanges may be made pursuant to such tender offer
or exchange offer; 
  
 in each case, whether such date is fixed
by the Board of Directors or by statute, contract or otherwise. 
  
 (g) The Company shall be entitled at its election to make such additional increases in the Conversion Rate, in addition to those required by Sections 12.3(a), (b), (c), (d) and (e), as shall be necessary in order that any dividend or
distribution of Common Stock, any subdivision, reclassification or combination of shares of Common Stock or any issuance of rights or warrants referred to above shall not be taxable to the holders of Common Stock for United States federal income tax
purposes. 
  
 (h) To the extent permitted by applicable law, the
Company may, from time to time, increase the Conversion Rate by any amount for any period of time, if such period is at least 20 days, the Board of Directors determines that the increase in the Conversion Rate is in the best interest of the Company,
and the increase is irrevocable during the period. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall mail to the Trustee and each Holder at the address of such Holder as it appears in the register of the
Securities maintained by the Registrar, at least 15 days prior to the date the increased Conversion Rate takes effect, a notice of the increase stating the increased Conversion Rate and the period during which it will be in effect. 
  
 (i) In any case in which this Section 12.3 shall require that any adjustment
be made effective as of or retroactively immediately following a Record Date, the Company may elect to defer (but only for five Trading Days following the filing of the statement referred to in Section 12.5) issuing to the Holder of any Securities
converted after such Record Date the shares of Common Stock issuable upon such conversion over and above the shares of Common Stock issuable upon such conversion on the basis of the Conversion Rate prior to adjustment; provided, however, that
the Company shall deliver to such Holder a due bill or other appropriate instrument evidencing such Holder’s right to receive such additional shares upon the occurrence of the event requiring such adjustment. 
  
 (j) All calculations under this Section 12.3 shall be made to the nearest
cent or one-hundredth of a share, with one-half cent and 0.005 of a share, respectively, being rounded 

  

 70 

 
upward. Notwithstanding any other provision of this Section 12.3, the Company shall not be required to make any adjustment of the Conversion Rate unless such
adjustment would require an increase or decrease of at least 1% of such rate. Any lesser adjustment shall be carried forward and shall be made at the time of and together with the next subsequent adjustment which, together with any adjustment or
adjustments so carried forward, shall amount to an increase or decrease of at least 1% in such rate. Any adjustments under this Section 12.3 shall be made successively whenever an event requiring such an adjustment occurs. 
  
 (k) In the event that at any time, as a result of an adjustment made pursuant
to this Section 12.3, the Holder of any Securities thereafter surrendered for conversion shall become entitled to receive any shares of stock of the Company other than shares of Common Stock into which the Securities originally were convertible, the
Conversion Rate of such other shares so receivable upon conversion of any such Security shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to Common Stock
contained in subparagraphs (a) through (j) of this Section 12.3, and the provision of Sections 12.1, 12.2 and 12.4 through 12.9 with respect to the Common Stock shall apply on like or similar terms to any such other shares and the good faith
determination of the Board of Directors as to any such adjustment shall be conclusive. 
  
 (l) No adjustment shall be made pursuant to this Section 12.3 if the Holders of the Securities may participate in the transaction that would otherwise give rise to an adjustment pursuant to this Section 12.3.

  
 Section 12.4. Consolidation or Merger of the Company.

  
 If any of the following events occurs, namely: 
  
 (a) any reclassification or change of the outstanding Common Stock (other
than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination) as a result of which all of the holders of Common Stock shall be entitled to receive stock, securities
or other property or assets (including Cash or any combination thereof) with respect to or in exchange for all of their Common Stock; 
  
 (b) any merger, consolidation, statutory share exchange or combination of the Company with another corporation as a result of which all of the holders of
Common Stock shall be entitled to receive stock, securities or other property or assets (including Cash or any combination thereof) with respect to or in exchange for all of their Common Stock; or 
  
 (c) any sale or conveyance of the properties and assets of the Company as, or
substantially as, an entirety to any other person as a result of which all of the holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including Cash or any combination thereof) with respect to or in
exchange for all of their Common Stock; 
  
 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, if such supplemental indenture is
then required to so comply) providing that the Holder’s right to convert a Security into Common 

  

 71 

 
Stock shall be changed to a right to convert a Security into the kind and amount of shares of stock and other securities or property or assets (including
Cash) which such Holder would have been entitled to receive upon such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance had such Securities been converted into Common Stock immediately prior
to such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance assuming such holder of Common Stock did not exercise its rights of election, if any, as to the kind or amount of securities, Cash or
other property receivable upon such merger, consolidation, statutory share exchange, sale or conveyance (provided, that if the kind or amount of securities, Cash or other property receivable upon such merger, consolidation, statutory share
exchange, sale or conveyance is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised (“Non-Electing Share”), then for the purposes of this Section 12.4, the kind and
amount of securities, Cash or other property receivable upon such merger, consolidation, statutory share exchange, sale or conveyance for each Non-Electing Share shall be deemed to be the kind and amount so receivable per share by a plurality of the
Non-Electing Shares). Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article XII. If, in the case of any such reclassification, change,
merger, consolidation, statutory share exchange, combination, sale or conveyance, the stock or other securities and assets receivable thereupon by a holder of Common Stock includes shares of stock or other securities and assets of a corporation
other than the successor or purchasing corporation, as the case may be, in such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, then such supplemental indenture shall also be executed by
such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors shall reasonably consider necessary by reason of the foregoing. 
  
 The Company shall cause notice of the execution of such supplemental
indenture to be mailed to each Holder, at the address of such Holder as it appears on the register of the Securities maintained by the Registrar, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or
validity of such supplemental indenture. 
  
 The above provisions
of this Section 12.4 shall similarly apply to successive reclassifications, changes, mergers, consolidations, statutory share exchanges, combinations, sales and conveyances. 
  
 If this Section 12.4 applies to any event or occurrence, Section 12.3 shall not apply. 
  
 Section 12.5. Notice of Adjustment. 
  
 Whenever an adjustment in the Conversion Rate with respect to the Securities
is required: 
  
 (a) the Company shall forthwith place on file
with the Trustee and any Conversion Agent for such securities a certificate of the Treasurer of the Company, stating the adjusted Conversion Rate determined as provided herein and setting forth in reasonable detail 

  

 72 

 
such facts as shall be necessary to show the reason for and the manner of computing such adjustment; and 
  
 (b) a notice stating that the Conversion Rate has been adjusted and setting
forth the adjusted Conversion Rate shall forthwith be given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company, to each Holder in the manner provided in Section 14.2 hereof. Any notice so
given shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. 
  
 Section 12.6. Notice in Certain Events. 
  
 In case: 
  
 (a) of a consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale or
conveyance to another Person or entity or group of Persons or entities acting in concert as a partnership, limited partnership, syndicate or other group (within the meaning of Rule 13d-3 under the Exchange Act) of all or substantially all of the
property and assets of the Company; or 
  
 (b) of the voluntary or
involuntary dissolution, liquidation or winding up of the Company; or 
  
 (c) of any action triggering an adjustment of the Conversion Rate referred to in clauses (y) or (z) below; 
  
 then, in each case, the Company shall cause to be filed with the Trustee and the Conversion Agent, and shall cause to be given, to the Holders of the Securities in the
manner provided in Section 14.2 hereof, at least 15 days prior to the applicable date hereinafter specified, a notice stating: 
  
 (y) the date on which a record is to be taken for the purpose of any distribution or grant of rights or warrants or other securities triggering an
adjustment to the Conversion Rate pursuant to this Article XII, or, if a record is not to be taken, the date as of which the holders of record of Common Stock entitled to such distribution, rights or warrants or other securities are to be
determined, or 
  
 (z) the date on which any reclassification,
consolidation, merger, sale, conveyance, dissolution, liquidation or winding up described under clauses (a), (b) and (c) of Section 12.4 that changes a Holder’s right to convert its Common Stock to a right to convert into another kind and
amount of securities or other property or assets is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property
deliverable upon such reclassification, consolidation, merger sale, conveyance, dissolution, liquidation or winding up. 
  
 Failure to give such notice or any defect therein shall not affect the legality or validity of the proceedings described in clause (a), (b) or (c) of this
Section 12.6. 
  

 73 

 Section 12.7. Company To Reserve Stock: Registration; Listing. 
  
 (a) The Company shall at all times reserve and keep available, free from
preemptive rights, out of its authorized but unissued shares of Common Stock for the purpose of effecting the conversion of the Securities, such number of its duly authorized shares of Common Stock as shall from time to time be sufficient to effect
the conversion of all Securities then outstanding into such Common Stock at any time (assuming that, at the time of the computation of such number of shares or securities, all such Securities would be held by a single Holder). The Company covenants
that all shares of Common Stock which may be issued upon conversion of Securities will upon issue be fully paid and nonassessable and free from all liens and charges and, except as provided in Section 12.8, taxes with respect to the issue thereof.

  
 (b) If any shares of Common Stock which would be issuable upon
conversion of Securities hereunder require registration with or approval of any governmental authority before such shares or securities may be issued upon such conversion, the Company will use its commercially reasonable efforts to cause such shares
or securities to be duly registered or approved, as the case may be. The Company further covenants that so long as the Common Stock shall be quoted on the Nasdaq National Market, the Company will use its commercially reasonable efforts, if permitted
by the rules of the Nasdaq National Market, to quote and keep quoted all Common Stock issuable upon conversion of the Securities, and the Company will use its commercially reasonable efforts to list the shares of Common Stock required to be
delivered upon conversion of the Securities prior to such delivery upon any other national securities exchange upon which the outstanding Common Stock is listed at the time of such delivery. 
  
 Section 12.8. Taxes on Conversion. 
  
 The issue of stock certificates on conversion of Securities shall be made
without charge to the converting Holder for any documentary, stamp or similar issue or transfer taxes in respect of the issue thereof, and the Company shall pay any and all documentary, stamp or similar issue or transfer taxes that may be payable in
respect of the issue or delivery of shares of Common Stock on conversion of Securities pursuant hereto. The Company shall not, however, be required to pay any such tax which may be payable in respect of any transfer involved in the issue or delivery
of shares of Common Stock or the portion, if any, of the Securities which are not so converted in a name other than that in which the Securities so converted were registered, and no such issue or delivery shall be made unless and until the Person
requesting such issue has paid to the Company the amount of such tax or has established to the satisfaction of the Company that such tax has been paid. 
  
 Section 12.9. Conversion After Record Date. 
  
 Except as provided in this Section 12.9, a converting Holder of Securities shall not be entitled to receive any accrued and unpaid interest (exclusive of
accrued and unpaid Liquidated Damages Amount, if any, which in any event shall be paid upon conversion in accordance with Section 12.2) on any such Securities being converted. By delivery to the Holder of the number of shares of Common Stock or
other consideration issuable or payable upon conversion in accordance with this Article XII, any accrued and unpaid interest on such Securities will be deemed to have been paid in full. If any Securities are surrendered for 

  

 74 

 
conversion subsequent to the record date preceding an Interest Payment Date but prior to such Interest Payment Date, the Holder of such Securities at the
close of business on such record date shall receive the interest payable (but not accrued and unpaid Liquidated Damages Amount, if any, with respect to such converted Security) on such Security on such Interest Payment Date notwithstanding the
conversion thereof. Securities surrendered for conversion during the period from the close of business on any record date preceding any Interest Payment Date to the opening of business on such Interest Payment Date shall be accompanied by payment
from converting Holders, for the account of the Company, in New York Clearing House funds, or other funds of an amount equal to the interest payable (but not accrued and unpaid Liquidated Damages Amount, if any, with respect to such converted
Security) on such Interest Payment Date on the Securities being surrendered for conversion; provided that no such payment is required if (a) the Company has specified a Redemption Date during the period from the close of business on any
record date preceding any Interest Payment Date through and including such Interest Payment Date or (b) any overdue interest exists at the time of the conversion with respect to the Securities converted, but only to the extent of the amount of such
overdue interest. 
  
 Except as provided in this Section 12.9, no
adjustments in respect of payments of interest on Securities surrendered for conversion or any dividends or distributions or interest on the Common Stock issued upon conversion shall be made upon the conversion of any Securities. 
  
 Section 12.10. Company Determination Final. 
  
 Any determination that the Company or the Board of Directors must make
pursuant to this Article XII shall be conclusive if made in good faith and in accordance with the provisions of this Article, absent manifest error, and set forth in a Board Resolution. 
  
 Section 12.11. Responsibility of Trustee for Conversion Provisions. 
  
 The Trustee has no duty to determine when an adjustment under this Article
XII should be made, how it should be made or what it should be. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities. The Trustee shall not be responsible for any failure of
the Company to comply with this Article XII. Each Conversion Agent other than the Company shall have the same protection under this Section 12.11 as the Trustee. 
  
 The rights, privileges, protections, immunities and benefits given to the Trustee under this Indenture including, without
limitation, its rights to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each Paying Agent or Conversion Agent acting hereunder. 
  
 Section 12.12. 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 XII 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.

 [FORM OF REVERSE OF SECURITY] 
  
 0.50% Convertible Senior Debentures due 2024 
  
 This Security is one of a duly authorized issue of 0.50% Convertible Senior Debentures due 2024 (the
“Securities”) of RED HAT, INC., a Delaware corporation (including any successor corporation under the Indenture hereinafter referred to, the “Company”), issued under an Indenture, dated as of January 12, 2004 (the
“Indenture”), between the Company and U.S. Bank Trust National Association, as trustee (the “Trustee”). The terms of the Security include those stated in the Indenture, those made part of the Indenture by reference
to the Trust Indenture Act of 1939, as amended (“TIA”), and those set forth in this Security. This Security is subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of all such terms. To
the extent permitted by applicable law, in the event of any inconsistency between the terms of this Security and the terms of the Indenture, the terms of the Indenture shall control. Capitalized terms used but not defined herein have the meanings
assigned to them in the Indenture referred to below unless otherwise indicated. 
  

	1.	Interest. 

  
 Interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months. 
  
 If this Security is redeemed pursuant to Section 5 of this Security or the
Holder elects to require the Company to repurchase this Security pursuant to Section 6 of this Security, on a date that is after the Regular Record Date and prior to the corresponding Interest Payment Date, interest and Liquidated Damages Amount, if
any, accrued and unpaid hereon to, but not including, the applicable Redemption Date, Repurchase Date or Repurchase Event Repurchase Date will be paid to the same Holder to whom the Company pays the principal of such Security regardless of whether
such Holder was the registered Holder on the Regular Record Date immediately preceding the applicable Redemption Date, Repurchase Date or Repurchase Event Repurchase Date. 
  
 Interest on Securities converted after the close of business on a Regular Record Date but prior to the opening of business
on the corresponding Interest Payment Date will be paid to the Holder of the Securities on the Regular Record Date but, upon conversion, the Holder must pay the Company the interest which have accrued and will be paid on such Interest Payment Date.
No such payment need be made with respect to Securities which will be converted after a Regular Record Date and prior to the corresponding Interest Payment Date if (i) the Company has specified a Redemption Date during the period from the close of
business on any record date preceding any Interest Payment Date through and including such Interest Payment Date or (ii) any overdue interest exists at the time of conversion with respect to the Securities converted, but only to the extent of the
amount of such overdue interest. 
  
 Upon conversion of this
Security, the Company will pay accrued and unpaid Liquidated Damages Amount, if any, to but not including the date of conversion to the Holder delivering the Security for conversion. 
  

 A-6 

 Except as otherwise stated herein, any reference herein to interest accrued or payable as of any date
shall include any Liquidated Damages Amount accrued or payable on such date as provided in the Registration Rights Agreement. 
  

	2.	Method of Payment. 

  
 Payment of the principal of and interest and Liquidated Damages Amount, if any, on the Securities shall be in such coin or currency of the United States
of America as at the time of payment is legal tender for payment of public and private debts or in Applicable Stock, as the case may be, as permitted in the Indenture. The Holder must surrender the Securities to the Paying Agent to collect payment
of principal. Payment of interest and Liquidated Damages Amount, if any, on Certificated Securities will be made by check mailed to the address of the Person entitled thereto as such address appears in the Register. Notwithstanding the foregoing, so
long as the Securities are registered in the name of a Depositary or its nominee, all payments with respect to the Securities shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. 

 

	3.	Paying Agent, Registrar, Conversion Agent and Bid Solicitation Agent. 

  

Initially, U.S. Bank Trust National Association will act as Paying Agent, Conversion Agent and Bid Solicitation Agent. The Company may appoint and
change any Paying Agent, Registrar, Conversion Agent or Bid Solicitation Agent without notice, other than notice to the Trustee; provided that the Company will maintain at least one Paying Agent in the State of New York, The City of New York,
Borough of Manhattan, which shall initially be an office or agency of the Trustee. The Company or any of its Subsidiaries or any of their Affiliates may act as Paying Agent, Registrar or Conversion Agent. None of the Company or any Subsidiary or any
Affiliate of any of them may act as Bid Solicitation Agent. 
  

	4.	Indenture. 

  
 The Securities are general unsecured obligations of the Company limited to up to $600,000,000 aggregate principal amount. The Indenture does not limit
other indebtedness of the Company, secured or unsecured. 
  

	5.	Redemption at the Option of the Company. 

  
 The Company may, at its option, redeem the Securities for Cash at any time as a whole, or from time to time in part, on or after January 15, 2009, at a
redemption price equal to 100% of the principal amount of Securities to be redeemed plus any accrued and unpaid interest and Liquidated Damages Amount, if any, on those Securities to, but not including, the Redemption Date. 
  
 Notice of redemption pursuant to this Section of this Security will 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 Cash 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 10:00 a.m., New York City time, on the Redemption Date, then on 

  

 A-7 

 
such Redemption Date interest and Liquidated Damages Amount, if any, cease to accrue on such Securities or portions thereof. Securities in denominations
larger than $1,000 of principal amount may be redeemed in part but only in multiples of $1,000 of principal amount. 
  

	6.	Repurchase By the Company at the Option of the Holder or Upon a Repurchase Event. 

  
 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 January 15, 2009, January 15, 2014 and January 15, 2019 in multiples of $1,000 at a repurchase price equal to 100% of the principal amount of those Securities plus accrued and
unpaid interest and Liquidated Damages Amount, if any, to, but not including, such 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 9:00 a.m., New York City time, on the date that is 20 Business Days immediately preceding such Repurchase Date until 5:00 p.m., New York City time, on the Business Day immediately preceding such Repurchase Date, and shall deliver the
Securities to the Paying Agent as set forth in the Indenture. 
  
 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 upon a Repurchase Event in multiples of $1,000 at
the Repurchase Event Repurchase Price. To exercise such right, a Holder shall deliver to the Paying Agent a Repurchase Event Repurchase Notice containing the information set forth in the Indenture, at any time prior to 5:00 p.m., New York City time,
on the Business Day immediately preceding the Repurchase Event Repurchase Date, and shall deliver the Securities to the Paying Agent as set forth in the Indenture. 
  
 Holders have the right to withdraw any Repurchase Notice or Repurchase Event Repurchase Notice 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 Repurchase Event Repurchase Price, as the case may be, of all Securities or portions thereof to be repurchased with respect to a Repurchase Date or Repurchase Event
Repurchase Date, as the case may be, has been deposited with the Paying Agent, at 10:00 a.m., New York City time, on the Repurchase Date or Repurchase Event Repurchase Date, as the case may be, then, immediately after the Repurchase Date or
Repurchase Event Repurchase Date, as applicable, such Securities will cease to be outstanding and interest and Liquidated Damages Amount, if any, on such Securities will cease to accrue and the Holder thereof shall have no other rights as such other
than the right to receive the Repurchase Price or Repurchase Event Repurchase Price upon surrender of such Security. 
  

	7.	Conversion. 

  
 Subject to and in compliance with the provisions of the Indenture (including, without limitation, the conditions to conversion of this Security set forth
in Section 12.1 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 a multiple of $1,000), into fully paid and 

  

 A-8 

 
nonassessable shares of Common Stock at the Conversion Rate in effect on the date of conversion. 
  
 The Company will notify Holders of any event triggering the right to convert
the Securities as specified above in accordance with the Indenture. 
  
 A Security in respect of which a Holder has delivered a Repurchase Notice or Repurchase Event Repurchase Notice, as the case may be, exercising the right of such Holder to require the Company to repurchase such Security may be converted
only if such Repurchase Notice or Repurchase Event Repurchase Notice is withdrawn in accordance with the terms of the Indenture. 
  
 The initial Conversion Rate is 39.0753 shares per $1,000 principal amount of Securities, subject to adjustment in certain events described in the
Indenture. 
  
 To surrender a Security for conversion, a Holder
must, in the case of Global Securities, comply with the Applicable Procedures of the Depositary in effect at that time, and in the case of Certificated Securities, (1) surrender the Security to the Conversion Agent, (2) complete and manually sign
the conversion notice below (or complete and manually sign a facsimile of such notice) and deliver such notice to the Conversion Agent, (3) furnish appropriate endorsements and transfer documents and (4) pay all funds required, if any, relating to
interest or Liquidated Damages Amount, if any, and any transfer or similar tax, if required. 
  
 No fractional share of Common Stock shall be issued upon conversion of any Security. Instead, the Company shall pay a Cash adjustment as provided in the Indenture. 
  
 No payment or adjustment will be made for accrued and unpaid interest or
dividends on the shares of Common Stock, except as provided in the Indenture. Accrued and unpaid Liquidated Damages Amount, if any, to but not including the date of conversion shall be paid to the Holder that delivers the Security for conversion.

  
 If the Company (i) is a party to a consolidation, merger,
statutory share exchange or combination of the Company with another corporation as a result of which all the holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including Cash or a combination thereof)
with respect to or in exchange for all of their Common Stock, (ii) reclassifies or changes the shares of Common Stock or (iii) conveys, transfers or leases its properties and assets as, or substantially as, an entirety to any person, the right to
convert a Security into shares of Common Stock may be changed to a right to convert a Security into the kind and amount of shares of stock and other securities or property or assets (including Cash) which such Holder would have been entitled to
receive upon such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance had such Holder converted its Security into Common Stock immediately prior to such transaction, in each case, in accordance
with the Indenture. 
  

 A-9 

	8.	Denominations; Transfer; Exchange. 

  
 The Securities are in fully registered form, without coupons, in denominations of $1,000 of principal amount and 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) or any Securities in respect of which a
Repurchase Notice or Repurchase Event Repurchase Notice has been given and not withdrawn (except, in the case of a Security to be repurchased in part, the portion of the Security not to be repurchased) or any Securities for a period of 15 days
before the mailing of a notice of redemption of Securities to be redeemed. 
  

	9.	Persons Deemed Owners. 

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

	10.	Unclaimed Money or Securities. 

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

	11.	Amendment; Waiver. 

  
 Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended with the written consent or affirmative vote
of the Holders of not less than a majority in aggregate principal amount of the outstanding Securities and (ii) certain Defaults may be waived with the written consent or affirmative vote of the Holders of not less than a majority in aggregate
principal amount of the outstanding Securities. 
  
 Without the
consent of any Securityholder, the Company and the Trustee may amend the Indenture or the Securities to (i) add to the covenants of the Company for the benefit of the Holders of Securities, (ii) surrender any right or power conferred upon the
Company in the Indenture, (iii) provide for the assumption 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 VII of the
Indenture, (iv) increase the Conversion Rate or reduce the Conversion Price; provided, however, that such increase in the Conversion Rate or reduction in the Conversion Price is in accordance with the terms of the Indenture or shall not

provision in the Indenture which may be inconsistent with any other provision therein or which is otherwise defective, or to make any other provisions with respect to matters or questions arising under the Indenture which the Company may deem
necessary or desirable and which shall not be inconsistent with the provisions of the Indenture; provided, however, that such action pursuant to this clause does not adversely affect the interests of the Holders of Securities, (xi) add or
modify any other provisions in the Indenture with respect to matters or questions arising thereunder which the Company and the Trustee may deem necessary or desirable and which would not adversely affect the interests of the Holders of Securities,
(xii) comply with the requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA, (xiii) provide for issuance of the Securities in coupon form; and (xiv) make provision with respect to the conversion

	12.	Defaults and Remedies. 

  
 If any Event of Default other than as a result of certain events of bankruptcy, insolvency or reorganization of the Company or its Significant
Subsidiaries occurs and is continuing, the principal of all the Securities may be declared due and payable in the manner and with the effect provided in the Indenture. If an Event of Default occurs as a result of certain events of bankruptcy,
insolvency or reorganization of the Company or its Significant Subsidiaries, the principal of all the Securities shall become due and payable immediately without any declaration or other act on the part of the Trustee or any Holder, all as and to
the extent provided in the Indenture. 
  

	13.	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. 
  

	14.	Calculations in Respect of Securities. 

  
 The Company or its agents will be responsible for making all calculations called for under the Securities including, but not limited to, determination of
the Market Price, Current Market Value and Sale Price of the Common Stock and the Applicable Stock, the number of shares of Common Stock or Applicable Stock issuable upon conversion and the amounts of interest and Liquidated Damages Amount, if any,
on the Securities. Any calculations made in good faith and without manifest error will be final and binding on Holders of the Securities. The Company or its agents will be required to deliver to the Trustee a schedule of its calculations and 

  

 A-11 

 
the Trustee will be entitled to conclusively rely upon the accuracy of such calculations without independent verification. 
  

	15.	No Recourse Against Others. 

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

 Exhibit 10.12 
  
 RED HAT, INC. 
 RESTRICTED STOCK AWARD AGREEMENT 
  
 THIS
RESTRICTED STOCK AWARD AGREEMENT is made and entered into on the 17th day of December, 2003, by and between RED HAT,
INC., a Delaware corporation (the “Company”), and Matthew J. Szulik (the “Employee”). 
  
 1. Discounted Sale. Subject to the restrictions and conditions set forth in this Agreement, the Company hereby agrees to sell to the Employee, not
in lieu of salary or other compensation, five hundred thousand (5000,000) shares of the Company’s Common Stock at the price of $0.50 per share (the “Restricted Shares”), upon Employee’s delivery to the Company of a check
in the amount of the total purchase price for the Restricted Shares. Employee hereby agrees with the restrictions and conditions set forth in this Agreement. 
  
 2. Forfeiture Restrictions. The Restricted Shares may not be sold, assigned, pledged, exchanged, hypothecated or otherwise transferred, encumbered
or disposed of voluntarily, by operation of law, pursuant to a court decree or legal process (including without limitation any interspousal transfer by court decree or order in connection with an equitable distribution of marital assets) or
otherwise to the extent the Restricted Shares are then subject to forfeiture and the Company’s right to repurchase the Restricted Shares to the Company upon the occurrence of certain events pursuant to paragraph 3 below (the “Forfeiture
Restrictions”). 
  
 3. Lapse of Forfeiture
Restrictions. The Forfeiture Restrictions shall lapse with respect to the Restricted Shares in accordance with the following schedule provided that the Employee has been continuously employed by the Company from the date of this Agreement
through the lapse date and no other event of forfeiture has occurred: 
  

			
	 Lapse Date

	  	 Number of Restricted Shares as to which
 Forfeiture Restrictions Lapse

	 March 17, 2004
	  	62,500
	 June 17, 2004
	  	62,500
	 September 17, 2004
	  	62,500
	 December 17, 2004
	  	62,500
	 March 17, 2005
	  	62,500
	 June 17, 2005
	  	62,500
	 September 17, 2005
	  	62,500
	 December 17, 2005
	  	62,500

  
 In the event the Employee voluntarily
elects to terminate employment with the Company, the Company shall have the right to repurchase from the Employee all such Restricted Shares at their sale price of $0.50 per share to the extent such shares are then subject to the Forfeiture
Restrictions; provided, however, any such repurchase shall not take place sooner than thirty (30) days following Employee’s last day of employment with the Company, during which thirty-day period Employee’s exercise rights shall continue.
The rights set forth in Section 1, and as limited by Sections 2 and 3, are cumulative and may be exercised only before the earlier of (a) the date which is ten (10) years from the date of this Agreement or (b) the date which is 120 days following
Employee’s last date of employment with the Company. 
  
 4.
Certificates. Upon payment of the purchase price, a certificate evidencing the Restricted Shares shall be issued by the Company in the Employee’s name, and the Employee shall have voting rights and shall be entitled to receive all
dividends paid with respect to the Restricted Shares unless and until the Restricted Shares are repurchased pursuant to the provisions of this Agreement. The certificate shall bear a legend evidencing the Forfeiture Restrictions, if any, remaining
in effect. The Company shall cause the certificate to be delivered upon issuance to the Secretary of the Company as a depository for safekeeping until a forfeiture occurs or the 

 
Forfeiture Restrictions lapse pursuant to the terms of this Agreement, and the Employee shall deliver to the Company a stock power relating to the Restricted
Shares in the form attached hereto as Exhibit A. Upon the lapse of the Forfeiture Restrictions without forfeiture, the Company shall cause a new certificate or certificates to be issued without legend in the name of the Employee for the
shares as to which the Forfeiture Restrictions have lapsed. Notwithstanding any other provisions of this Agreement, the issuance or delivery of any shares (whether subject to restrictions or unrestricted) may be postponed for such period as may be
required to comply with applicable requirements of any national securities exchange or any requirements under any law or regulation applicable to the issuance or delivery of such shares. 
  
 5. Withholding of Tax. To the extent that the sale of the Restricted Shares or the lapse of the Forfeiture
Restrictions results in income to the Employee for federal, state or local income or employment tax purposes, the Employee shall deliver to the Company at the time of such receipt or lapse, as the case may be, such amount of money as the Company may
require to meet its withholding obligation under applicable tax laws or regulations, and, if the Employee fails to do so, the Company is authorized to withhold from any cash remuneration then or thereafter payable to the Employee any tax required to
be withheld by reason of such income. 
  
 6. Status of
Restricted Shares. The Employee agrees that the Restricted Shares will not be sold or otherwise disposed of in any manner which would constitute a violation of any applicable federal or state securities laws. 
  
 7. No Right to Employment. This Agreement shall not confer upon
the Employee any right to continued employment with the Company, nor shall it interfere in any way with the right of the Company to terminate the employment of the Employee. 
  
 8. Binding Effect. This Agreement shall be binding upon and inure to the benefit of any successors to the Company and
all persons lawfully claiming under the Employee. 
  
 9.
Multiple Originals. This Agreement is executed in multiple originals, one of which is being retained by each of the parties hereto and each of which shall be deemed an original hereof. 
  
 10. Governing Law. The Agreement and all actions taken
thereunder shall be governed by and construed in accordance with the laws of the State of North Carolina. 
  
 IN WITNESS WHEREOF, the Company has caused this Agreement to be executed by its duly authorized officer, and the Participant has hereunto set the
Participant’s hand and seal, all as of the day and year first above written.
