 ARTICLE 2 
 THE SECURITIES 
 Section 2.01. Form and Dating. 
 (a) General. The Securities and the Trustee’s certificate of authentication shall be substantially in the respective forms set forth in
Exhibit A, which Exhibit is incorporated in and made part of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange Rule or usage. 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. The terms and provisions contained in the Securities shall constitute, and are hereby expressly made, a part of this Indenture, and the Company and
the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Security conflicts with the express provisions of this Indenture, the
provisions of this Indenture shall govern and be controlling. 
 (b) Global Securities. All of the Securities shall be issued
initially in the form of one or more Global Securities, which shall be deposited on behalf of the purchasers of the Securities represented thereby with the Trustee, at its Corporate Trust Office, as custodian for the depositary, The Depository Trust
Company (“DTC”) (such depositary, or any successor thereto, being hereinafter referred to as the “Depositary”), and registered in the name of its nominee, Cede & Co., duly executed by the Company and
authenticated by the Trustee as hereinafter provided. 
 Each Global Security shall represent such of the outstanding Securities as shall be
specified therein and each shall provide that it shall represent the aggregate amount of outstanding Securities from time to time endorsed thereon and that the aggregate amount of outstanding Securities represented thereby may from time to time be
reduced or increased, as appropriate, to reflect exchanges, purchases or 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 hereof and shall be made on the records of the Trustee and the Depositary.

 Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture with respect
to any Global Security held on their behalf by the Depositary or under the Global Security, and the Depositary (including, for this purpose, its nominee) 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 

  

 12 

 
foregoing, nothing herein shall (i) prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written
certification, proxy or other authorization furnished by the Depositary or (ii) impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Security.

 (c) Book Entry Provisions. The Company shall execute and the Trustee shall, in accordance with this Section 2.01(c),
authenticate and deliver initially one or more Global Securities that (i) shall be registered in the name of the Depositary, (ii) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary’s instructions and
(iii) shall bear a legend substantially to the following effect: 
 “UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED
REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE, CONVERSION OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS
REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY), ANY TRANSFER.
PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. THIS NOTE IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED
TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE THEREOF. THIS NOTE IS EXCHANGEABLE FOR SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE
AND UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR SECURITIES IN DEFINITIVE FORM, THIS NOTE 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”. 
  

 13 

 Section 2.02. Execution and Authentication. An Officer shall sign the Securities for the
Company by manual or facsimile signature attested by the manual or facsimile signature of the Secretary or an Assistant Secretary of the Company. Typographic and other minor errors or defects in any such facsimile signature shall not affect the
validity or enforceability of any Security which has been authenticated and delivered by the Trustee. 
 If an Officer whose signature is on
a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless. 
 A
Security shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture.

 Subject to the third sentence of this paragraph, the Trustee shall authenticate and make available for delivery Securities for original
issue in the aggregate principal amount of up to $[            ] (or such greater amount necessary to reflect the exercise by the Underwriters of their option to purchase additional
Securities in compliance with the Underwriting Agreement, dated September [    ], 2007, between the Company and the Underwriters (the “Underwriting Agreement”) but not to exceed
$[            ] in aggregate principal amount) upon receipt of a written order or orders of the Company signed by two Officers, at least one of whom shall be the principal executive
officer, principal financial officer or principal accounting officer of the Company (a “Company Order”). The Company Order shall specify the amount of Securities to be authenticated, shall provide that all such Securities will be
represented by a Global Security and the date on which each original issue of Securities is to be authenticated. The Company at any time or from time to time may, without the consent of any Holder, issue additional Securities in an unlimited
principal amount having the same terms (including ranking, interest rate and maturity) and having the same CUSIP number as the Securities initially issued hereunder, and entitled to all of the benefits of this Indenture, provided that no such
additional Securities may be issued unless for U.S. federal income tax purposes they are fungible with the Securities initially issued hereunder. Such additional Securities will be deemed Securities for all purposes hereunder, including without
limitation in determining the necessary Holders who may take the actions or consent to the taking of actions as specified in this Indenture. Such additional Securities, together with the Securities originally issued hereunder, constitute a single
series of Securities under this Indenture. 
  

 14 

 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. An authenticating agent shall have the same rights as an Agent to deal with the Company or an Affiliate of the Company. 
 The
Securities shall be issuable only in registered form without coupons and only in denominations of $1,000 principal amount and any integral multiple thereof. 
 Section 2.03. Registrar, Paying Agent and Conversion Agent. The Company shall maintain one or more offices or agencies where Securities may be presented for registration of transfer or for exchange (each,
a “Registrar”), one or more offices or agencies where Securities may be presented for payment (each, a “Paying Agent”), one or more offices or agencies where Securities may be presented for conversion (each, a
“Conversion Agent”) and one or more offices or agencies where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Company will at all times maintain a Paying Agent,
Conversion Agent, Registrar 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, The City of New York. One of the Registrars (the
“Primary Registrar”) shall keep a register of the Securities and of their registration of transfer and exchange. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such
office or agency. 
 The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture. The agreement
shall implement the provisions of this Indenture that relate to such Agent. The Company shall give prompt written notice to the Trustee of the name and address of any Agent not a party to this Indenture. If the Company fails to maintain a Registrar,
Paying Agent, Conversion Agent or agent for service of notices and demands in any place required by this Indenture, or fails to give the foregoing notice, the Trustee shall act as such. The Company or any Affiliate of the Company may act as Paying
Agent (except for the purposes of Section 6.01 and Article 10). 
 The Company hereby initially designates the Trustee as Paying Agent,
Registrar, Custodian and Conversion Agent and each of the Corporate Trust Office of the Trustee and the office or agency of the Trustee in the Borough of Manhattan, The City of New York, as an office or agency of the Company for each of the
aforesaid purposes. 
  

 15 

 Section 2.04. Paying Agent to Hold Money in Trust. Prior to 11:00 a.m., New York
City time, on each due date of the principal of, premium, if any, any Extension Fee or interest on any Securities, the Company shall deposit with a Paying Agent a sum sufficient to pay such principal, premium, Extension Fee or interest so becoming
due. A Paying Agent shall hold in trust for the benefit of Securityholders or the Trustee all money held by the Paying Agent for the payment of principal of, premium or interest on the Securities, and shall notify the Trustee of any default by the
Company (or any other obligor on the Securities) in making any such payment. If the Company or an Affiliate of the Company acts as Paying Agent, it shall, before 11:00 a.m., New York City time, on each due date of the principal of,
premium, if any, Extension Fee or interest on any Securities, segregate the money and hold it as a separate trust fund for the benefit of the Securityholders. The Company at any time may require a Paying Agent to pay all money held by it to the
Trustee, and the Trustee may at any time during the continuance of any default, upon written request to a Paying Agent, require such Paying Agent to pay forthwith to the Trustee all sums so held in trust by such Paying Agent. Upon doing so, the
Paying Agent (other than the Company) shall have no further liability for the money. 
 Section 2.05. 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, and the Trustee shall otherwise comply with TIA Section 312(a). If the Trustee is not
the Primary Registrar, the Company shall furnish to the Trustee at least seven Business Days 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, and the Company shall otherwise comply with TIA Section 312(a). 
 Section 2.06. Transfer and Exchange.  
 (a) Subject to compliance with any applicable additional requirements contained
in Section 2.12, when a Security is presented to a Registrar with a request to register a transfer thereof or to exchange such Security for an equal principal amount of Securities of 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, and in form satisfactory to the Registrar 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 pursuant to Section 2.03, the Company shall execute and the Trustee shall authenticate Securities of a like aggregate principal amount at the
Registrar’s request. Any exchange or registration of transfer shall 

  

 16 

 
be without charge, except that the Company or the Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto, and provided, that this sentence shall not apply to any exchange pursuant to Sections 2.07, 2.10, 4.03 (last paragraph) or 11.06. 
 Neither the Company, any Registrar nor the Trustee shall be required to exchange or register a transfer of any Securities or portions thereof in respect of which a Repurchase Exercise Notice pursuant to
Section 3.08(c) hereof has been delivered and not withdrawn by the Holder thereof (except, in the case of the repurchase of a Security in part, the portion thereof not to be repurchased). 
 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 2.03 hereof shall provide to the Trustee such information as the Trustee may reasonably require in connection with the delivery by such Registrar of Securities upon transfer or exchange of Securities. 
 (c) Each Holder agrees to indemnify the Company, each Registrar and the Trustee against any liability that may result from the registration of 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. 
 Section 2.07. Replacement Securities. If any mutilated Security is surrendered to the Company, a Registrar or the Trustee, or the Trustee
receives evidence to its satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company, the applicable Registrar and the Trustee such security or indemnity as will be required by them to save each of them
harmless, then, in the absence of notice to the Company, such Registrar or the Trustee that such Security has been acquired by a 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 number not contemporaneously outstanding. 
  

 17 

 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 repurchased by the Company pursuant to Article 3, the Company in its discretion may, instead of issuing a new Security, pay or repurchase such Security, as the case may be. 
 Upon the issuance of any new Securities under this Section 2.07, the Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the reasonable fees and expenses of the Trustee or the Registrar) in connection therewith. 
 Every new Security issued pursuant to this Section 2.07 in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with
any and all other Securities duly issued hereunder. 
 The provisions of this Section 2.07 are (to the extent lawful) exclusive and
shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 
 Section 2.08. Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee, except for those canceled by it, those converted pursuant to Article 4, those
delivered to it for cancellation or surrendered for transfer or exchange and those described in this Section 2.08 as not outstanding. 
 If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a protected purchaser. 
 If a Paying Agent (other than the Company or an Affiliate of the Company) holds on a Fundamental Change Repurchase Date or the Final Maturity Date money
sufficient to pay the principal of, premium, if any, any Extension Fees and accrued interest on Securities (or portions thereof) payable on that date, then on and after such Fundamental Change Repurchase Date or the Final Maturity Date, as the case
may be, such Securities (or portions thereof, as the case may be) shall cease to be outstanding and interest on them shall cease to accrue. 
  

 18 

 Subject to the restrictions contained in Section 2.09, a Security does not cease to be outstanding
because the Company or an Affiliate of the Company holds the Security. 
 Section 2.09. Treasury Securities. In determining
whether the Holders of the required principal amount of Securities have concurred in any notice, direction, waiver or consent, Securities owned by the Company or any other obligor on the Securities or by any Affiliate of the Company or of such other
obligor shall be disregarded, except that, for purposes of determining whether the Trustee shall be protected in relying on any such notice, direction, waiver or consent, only Securities that a Responsible Officer of the Trustee actually knows are
so owned shall be so disregarded. Securities so owned that have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to the Securities and
that the pledgee is not the Company or any other obligor on the Securities or any Affiliate of the Company or of such other obligor. 
 Section 2.10. Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and execute, and, upon receipt of a Company Order, the Trustee shall authenticate and deliver, temporary Securities.
Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities and as shall be reasonably acceptable to the Trustee. Without unreasonable
delay, the Company shall prepare and the Trustee, upon receipt of a Company Order, shall authenticate and deliver definitive Securities in exchange for temporary Securities. 
 Holders of temporary Securities shall be entitled to all the benefits of this Indenture. 
 Section 2.11. Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar, the Paying Agent
and the Conversion Agent shall forward to the Trustee or its agent any Securities surrendered to them for registration of transfer, exchange, payment or conversion. The Trustee (and no one else) shall promptly cancel, in accordance with its standard
procedures, all Securities surrendered for registration of transfer, exchange, payment, conversion or cancellation and shall dispose of canceled Securities (subject to the record retention requirements of the Exchange Act), in accordance with its
standard procedures. All Securities that are repurchased by the Company in connection with a Fundamental Change prior to the Final Maturity Date shall be delivered to the Trustee for cancellation. The Company may not hold or resell such Securities
or issue new Securities to replace Securities that it has repurchased in connection with a Fundamental Change or that have been delivered to the Trustee for cancellation. 
  

 19 

 Section 2.12. Additional Transfer and Exchange Requirements. 
 (a) A Global Security may not be transferred, in whole or in part, to any Person other than the Depositary or a nominee or any successor thereof, and no
such transfer to any such other Person may be registered; provided that the foregoing shall not prohibit any transfer of a Security that is issued in exchange for a Global Security but is not itself a Global Security. No transfer of a
Security to any Person shall be effective under this Indenture or the Securities unless and until such Security has been registered in the name of such Person. Notwithstanding any other provisions of this Indenture or the Securities, transfers of a
Global Security, in whole or in part, shall be made only in accordance with this Section 2.12. 
 (b) The provisions of
clauses (i), (ii), (iii) and (iv) below shall apply only to Global Securities: 
 (i) Notwithstanding any other
provisions of this Indenture or the Securities, a Global Security shall not be exchanged in whole or in part for a Security registered in the name of any Person other than the Depositary or one or more nominees thereof; provided that a Global
Security may be exchanged for Securities registered in the names of any person designated by the Depositary in the event that (A) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such Global
Security or such Depositary has ceased to be a “clearing agency” registered under the Exchange Act, and a successor Depositary is not appointed by the Company within 90 days, (B) the Company has provided the Depositary with
written notice that it has decided to discontinue use of the system of book-entry transfer through the Depositary or any successor Depositary or (C) an Event of Default has occurred and is continuing. Any Global Security exchanged pursuant to
clauses (A) or (B) above shall be so exchanged in whole and not in part, and any Global Security exchanged pursuant to clause (C) above may be exchanged in whole or from time to time in part as directed by the Depositary. Any Security
issued in exchange for a Global Security or any portion thereof shall be a Global Security; provided that any such Security so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a
Global Security. 
 (ii) Securities issued in exchange for a Global Security or any portion thereof shall be issued in
definitive, fully-registered book entry form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Security or portion thereof to be so exchanged, shall be registered in such names and be in such authorized
denominations as the Depositary shall designate and shall bear any applicable legend provided for herein. Any Global Security to be exchanged in whole shall 

  

 20 

 
be surrendered by the Depositary to the Trustee, as Registrar. With regard to any Global Security to be exchanged in part, either such Global Security shall
be so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with respect to such Global Security, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so
exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Security issuable on such exchange to or upon the order of the Depositary or
an authorized representative thereof; provided, however, that any Global Security surrendered for exchange shall be duly endorsed or accompanied by a written instrument of transfer in accordance with the proviso to the first paragraph
of Section 2.06(a). 
 (iii) Subject to the provisions of clause (v) below, the registered Holder may grant proxies
and otherwise authorize any Person, including Agent Members and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Securities. 
 (iv) In the event of the occurrence of any of the events specified in clause (i) above, the Company will promptly make available to
the Trustee a reasonable supply of Certificated Securities in definitive, fully registered form, without interest coupons. 
 (v) Neither Agent Members nor any other Persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Security registered in the name of the Depositary or any nominee thereof, or under
any such Global Security, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and holder of such Global Security for all purposes
whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or
such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a
holder of any Security. 
 (c) 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(b)(i) which required such exchange shall cease to exist, the Company shall deliver notice to the Trustee and to the Holders stating that 

  

 21 

 
Holders may exchange Certificated Securities for 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 with a request: 
 (i) to register the transfer of such Certificated Securities to a person who will take delivery thereof in the form of a beneficial
interest in a Global Security; or 
 (ii) 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, 
 the Registrar
shall register the transfer or make the exchange as requested by canceling such Certificated Securities and causing, or directing the Custodian to cause, 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, upon receipt of a Company Order, shall authenticate and deliver a new Global Security; provided, however, that the Certificated Securities
presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in accordance with the proviso to the first paragraph of Section 2.06(a). 
 Section 2.13. CUSIP Numbers. The Company in issuing the Securities may use one or more “CUSIP” numbers (if then generally in
use), and, if so, the Trustee shall use “CUSIP” numbers in notices of repurchase as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either
as printed on the Securities or as contained in any notice of a repurchase and that reliance may be placed only on the other identification numbers printed on the Securities, and any such repurchase 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.
Repurchases. The Company may from time to time repurchase the Securities in tender offers, open market purchases or negotiated transactions at any price without prior notice to Securityholders.

 Section 3.08. Repurchase at Option of the Holder upon a Fundamental Change.

 (a) Subject to the satisfaction of the requirements of this Section 3.08, if a Fundamental Change occurs, each Holder will, upon
receipt of the notice of the occurrence of a Fundamental Change described in Section 3.08(b), have the right to require the Company to repurchase for cash any or all of such Holder’s Securities, or any portion of those Securities that is
equal to $1,000 or an integral multiple of $1,000, on the date (the “Fundamental Change Repurchase Date”) that is 45 days after the date the Company gives the Fundamental Change Repurchase Notice at a price equal to 100% of the
principal amount of the Securities to be repurchased plus accrued and unpaid interest, if any, to (but excluding) the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”). 
 (b) Within 30 days after the occurrence of a Fundamental Change, the Company shall provide to all Holders of the Securities, the Trustee and the Paying
Agent a notice of the occurrence of the Fundamental Change and of the resulting repurchase right (the “Fundamental Change Repurchase Notice”). 
 (c) To exercise the repurchase right in connection with a Fundamental Change, a Holder must, prior
to 5:00 p.m., New York City time, on the 30th day after the date of the Fundamental Change Repurchase Notice, deliver the Securities to be
repurchased to the Paying Agent, duly endorsed for transfer, or effect book-entry transfer of the Securities to the Paying Agent, and must deliver a written notice of repurchase (a “Repurchase Exercise Notice”), substantially in the
form included in Exhibit A hereto, duly completed to the Paying Agent. The Repurchase Exercise Notice must state: 
 (i) if the Securities are certificated, the certificate numbers of the Securities to be delivered for repurchase; 
  

 23 

 (ii) the portion of the principal amount of the Securities to be repurchased, which must
be equal to $1,000 or an integral multiple thereof; and 
 (iii) that the Securities are to be repurchased by the Company
as of the Fundamental Change Repurchase Date pursuant to the applicable provisions of the Securities and this Indenture. 
 If the Securities
are not in certificated form, the Repurchase Exercise Notice must comply with the Applicable Procedures. 
 A Holder may withdraw any
Repurchase Exercise Notice (in whole or in part) by a written notice of withdrawal delivered to the Paying Agent prior to 5:00 p.m., New York City time, on the Fundamental Change Repurchase Date. The notice of withdrawal must state:

 (i) the principal amount of the Securities for which the Repurchase Exercise Notice has been withdrawn; 
 (ii) if certificated Securities have been issued, the certificate numbers of the withdrawn Securities; and 
 (iii) the principal amount, if any, that remains subject to the Repurchase Notice. 
 If the Securities are not in certificated form, the withdrawal notice must comply with the Applicable Procedures. 
 (d) The Company shall promptly pay the Fundamental Change Repurchase Price for Securities surrendered for repurchase following the Fundamental Change
Repurchase Date. 
 Section 3.09. Compliance with Securities Laws upon Repurchase of Securities. In connection with any offer to
purchase or purchase of Securities under Section 3.08, the Company shall comply with all tender offer rules applicable to the Company under the Exchange Act. The Company shall (a) comply with Rule 13e-4 and Rule 14e-l (or any
successor to either such Rule), if applicable, under the Exchange Act, (b) file the related Schedule TO (or any successor or similar schedule, form or report) if required under the Exchange Act, and (c) otherwise comply with all
federal and state securities laws in connection with such offer to purchase or purchase of Securities, all so as to permit the rights of the Holders and obligations of the Company under Sections 3.08 and 4.08 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 Section 3.09, the Company will comply with the applicable securities laws and regulations and will not be
deemed to have breached its obligations under this Section 3.09 by virtue of such conflict. 
  

 24 

 Section 3.10. Repayment to the Company. To the extent that the aggregate amount of cash
deposited by the Company pursuant to Section 3.08 exceeds the aggregate Fundamental Change Repurchase Price together with interest, if any, thereon of the Securities or portions thereof that the Company is obligated to purchase, then promptly
after the Fundamental Change Repurchase Date, the Trustee or a Paying Agent, as the case may be, shall return any such excess cash to the Company. 
 ARTICLE 4 
 CONVERSION 
 Section 4.01. Right to Convert. (a) Subject to and upon compliance with the provisions of this Indenture, at any time prior to the Close of Business on the Business Day immediately preceding the Final
Maturity Date, a Holder of any Security shall have the right, at such Holder’s option, to convert the Security, unless such Security has been previously repurchased, at the Conversion Rate. 
 Upon receipt by the Conversion Agent of a Conversion Notice from a Holder of Securities pursuant to this clause (a), the Conversion Agent shall
inform the Company of such request (and, if the Conversion Agent is other than the Trustee, inform the Trustee). 
 (a) A Security in respect
of which a Holder is electing to exercise its option to require repurchase upon a Fundamental Change pursuant to Section 3.08 may be converted only if such holder withdraws its election in accordance with Section 3.08(c). A Holder of
Securities is not entitled to any rights of a holder of Common Stock until such Holder has converted such Securities for Common Stock, and only to the extent such Securities are deemed to have been converted for Common Stock under this Article 4.

 Section 4.02. Conversion Rate. The conversion rate per $1,000 principal amount of Securities to be converted (the
“Conversion Rate”) will be determined as follows: 
  

	 	•	 	 If the Applicable Stock Price is less than or equal to the Base Conversion Price, the Conversion Rate will be the Base Conversion Rate.

  

	 	•	 	 If the Applicable Stock Price is greater than the Base Conversion Price, the Conversion Rate will be determined in accordance with the following formula:

  

									
	Base Conversion Rate +	 	[	 	(the Applicable Stock Price –the Base Conversion Price)	 	x the Incremental Share Factor	 	 ]

	 	 	the Applicable Stock Price	 		 

  

 25 

 The Conversion Rate, including any Additional Shares added to the Conversion Rate pursuant to Section
4.08(a), will not exceed [    ]; however, such maximum Conversion Rate shall be appropriately adjusted for all adjustments to the Base Conversion Rate (and adjustments to the Incremental Share Factor) pursuant to Section
4.07. 
 The “Base Conversion Rate” per $1,000 principal amount of Securities is [    ], subject
to adjustment pursuant to Section 4.07. 
 The “Base Conversion Price” is a dollar amount (initially
$[            ]) derived by dividing $1,000 by the Base Conversion Rate. 
 The “Incremental Share Factor” is [    ], subject to the same proportional adjustments as the Base Conversion Rate. 
 The “Applicable Stock Price” is equal to the average of the Sale Prices of the
Common Stock over the 10-Trading Day period starting the third Trading Day following the Conversion Date of the Securities; provided that with respect to Securities surrendered for conversion on or after the 13th Scheduled Trading Day immediately preceding the Final Maturity Date, the “Applicable Stock Price” shall be equal to the average of the Sale Prices of the Common
Stock over the 10-Trading Day period immediately preceding the Final Maturity Date. The 10-Trading Day period used to determine the Applicable Stock Price is the “Averaging Period”. 
 Section 4.03. Conversion Procedures. To convert a Security, a Holder must (a) complete and manually sign the conversion notice on the
back of the Security (“Conversion Notice”) or a facsimile of the Conversion Notice and deliver such notice to a Conversion Agent, (b) surrender the Security to a Conversion Agent, (c) furnish appropriate endorsements and
transfer documents if required by a Registrar or a Conversion Agent, (d) pay any transfer or similar tax, if required and (e) pay funds equal to interest payable on the next interest payment date, if required. The date on which the Holder
satisfies all of those requirements is the “Conversion Date”. Anything herein to the contrary notwithstanding, in the case of Global Securities, Conversion Notices may be delivered and such Securities may be surrendered for
conversion in accordance with the Applicable Procedures as in effect from time to time. 
 The Person in whose name the Common Stock
certificate is registered shall be deemed to be a stockholder of record at 5:00 p.m., New York City time on the applicable Conversion Date; provided, however, that if the Conversion Date is a date when the stock transfer books of
the Company are closed, such Person shall be deemed a stockholder of record on the next date on which the 

  

 26 

 
stock transfer books of the Company are open; provided further that such conversion shall be at the Conversion Rate as if the stock transfer books of
the Company had not been closed on the Conversion Date. 
 Upon conversion of a Security, a Holder will not receive any cash payment of
interest (unless such conversion occurs between a Record Date and the related Interest Payment Date), and the Company will not adjust the Conversion Rate to account for accrued and unpaid interest on the Security being converted. Delivery to the
Holder of the full number of shares of Common Stock into which the Security is convertible, together with any cash payment for fractional shares pursuant to Section 4.06, will be deemed to satisfy the Company’s obligation with respect to
such Security. Any accrued but unpaid interest will be deemed to be paid in full upon conversion rather than canceled, extinguished or forfeited. 
 Holders of Securities at the close of business on a Record Date will receive payment of interest payable on the related Interest Payment Date notwithstanding the conversion of such Securities at any time after 5:00 p.m., New York
City time on the Record Date and prior to the related Interest Payment Date. Securities or portions thereof surrendered for conversion during the period from 5:00 p.m., New York City time on a Record Date to 5:00 p.m., New York
City time on the Business Day immediately preceding the related Interest Payment Date shall be accompanied by payment to the Company or its order, in immediately available funds or other funds acceptable to the Company, of an amount equal to the
interest payable on such Interest Payment Date with respect to the principal amount of Securities or portions thereof being surrendered for conversion; provided that no such payment need be made (1) following 5:00 p.m.,
New York City time on the regular Record Date immediately preceding the final Interest Payment Date, (2) if the Company has specified a Fundamental Change Repurchase Date that occurs during the period from 5:00 p.m., New York
City time on a Record Date to 5:00 p.m., New York City time on the related Interest Payment Date, or (3) to the extent any overdue interest exists on the Conversion Date with respect to the Securities converted, but only to the extent
of such overdue interest. 
 If a Holder converts more than one Security at the same time, the number of shares of Common Stock issuable upon
the conversion shall be based on the aggregate principal amount of Securities converted. 
 Upon surrender of a Security that is converted in
part, the Company shall execute, and the Trustee shall authenticate and deliver to the holder, a new Security equal in principal amount to the principal amount of the unconverted portion of the Security surrendered. 
  

 27 

 Section 4.04. Payment upon Conversion. Upon the conversion of a Security, subject to
Section 4.03, the Company shall deliver shares of Common Stock, together with cash in lieu of any fractional shares, to the Holder through the Conversion Agent. No payment or adjustment shall be made for dividends on, or other distributions
with respect to, any Common Stock except as provided in this Article 4. 
 The Company will not issue fractional shares of Common Stock upon
conversion of Securities. Instead, the Company will pay cash for all fractional shares of Common Stock in an amount based on the Sale Price of the Common Stock on the Trading Day immediately preceding the Conversion Date. 
 The Conversion Agent shall, on behalf of the Holders, convert the Securities into shares of Common Stock, together with any cash in lieu of fractional
shares as provided in Section 4.06 below. 
 Settlement of the Company’s obligation to deliver shares of Common Stock and cash in
lieu of fractional shares will occur no later than the third Business Day immediately following the Averaging Period, except as set forth in Section 4.08 below. Delivery of shares of Common Stock shall be accomplished by delivery to the
Conversion Agent of certificates for the relevant number of shares of Common Stock, other than in the case of Holders of Securities in book-entry form with DTC, in which case, shares of Common Stock shall be delivered in accordance with DTC’s
customary practices. 
 Section 4.05. Exchange in Lieu of Conversion. (a) In lieu of its obligations pursuant to
Section 4.04, the Company may, at its option, direct the Conversion Agent to surrender, on or prior to the commencement of the Averaging Period, Securities tendered for conversion to a financial institution (the “Financial
Institution”) designated by the Company for exchange in lieu of conversion. In order to accept any Securities surrendered for conversion, the Financial Institution must agree to deliver, in exchange for the Securities, shares of Common
Stock equal to the Conversion Rate, together with cash in lieu of any fractional shares. By 5:00 p.m., New York City time on the Trading Day immediately preceding the start of the Averaging Period, the Company will notify the Holder
surrendering Securities for conversion that it has designated a Financial Institution to make an exchange in lieu of conversion. 
 If the
Financial Institution accepts any such Securities, it shall deliver shares of Common Stock, together with cash in lieu of any fractional shares, to the Conversion Agent and the Conversion Agent shall deliver such shares of Common Stock, together
with cash in lieu of any fractional shares, to the Holder who has tendered such Securities for conversion. If the Financial Institution agrees to accept any Securities for exchange but does not timely deliver the related consideration, or if the
Financial Institution does not accept the Securities 

  

 28 

 
for exchange, the Company shall, as promptly as practical thereafter, but not later than the third Trading Day immediately following the last day of the
Averaging Period, convert such Securities into shares of Common Stock as provided in Section 4.04 above. 
 The Company’s
designation of a financial institution to which the Securities may be submitted for exchange does not require the institution to accept any Securities. The Company will not pay consideration to, or otherwise enter into any agreement with, the
Financial Institution for or with respect to such designation. 
 Section 4.06. Cash Payments in Lieu of Fractional Shares. No
fractional shares of Common Stock or scrip certificates representing fractional shares shall be issued upon conversion of Securities. If more than one Security shall be surrendered for convert at one time by the same Holder, the number of full
shares of Common Stock that shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted hereby) so surrendered. 
 Section 4.07. Adjustment of Conversion Rate. (a) The Base Conversion Rate shall be adjusted (and the Incremental Share Factor shall be
proportionally adjusted in the same manner) from time to time by the Company as follows: 
 (i) In case the Company shall
issue shares of Common Stock as a dividend or distribution on its Common Stock or subdivide or combine its outstanding Common Stock, the Base Conversion Rate shall be adjusted based on the following formula: 
 

 
 where, 
  

							
		 	CR0	 	=	  	the Base Conversion Rate in effect immediately prior to the Ex Date for such dividend or distribution or the effective date of such subdivision or combination, as the case may
be;
				
		 	CR1	 	=	  	the Base Conversion Rate in effect immediately on and after the Ex Date for such dividend or distribution or the effective date of such subdivision or combination, as the case may
be;
				
		 	OS0	 	=	  	the number of shares of Common Stock outstanding immediately prior to the Ex Date for such dividend or distribution or the effective date of such subdivision or combination, as the case may
be; and

  

 29 

							
		 	OS1	 	=	  	the number of shares of Common Stock outstanding immediately on and after the Ex Date for such dividend or distribution or the effective date of such subdivision or combination, as the case
may be.

 Such adjustment shall become effective immediately after 9:00 a.m., New York City time,
on the Business Day following the Ex Date for such dividend, distribution, subdivision or combination. The Company will not pay any dividend or make any distribution on shares of Common Stock held in treasury by the Company. If any dividend or
distribution of the type described in this Section 4.07(a)(i) is declared but not so paid or made, or the outstanding shares of Common Stock are not subdivided or combined, as the case may be, the Base Conversion Rate shall again be adjusted to
the Base Conversion Rate which would then be in effect if such dividend, distribution, subdivision or combination had not been declared. 
 (ii) In case the Company shall issue rights or warrants to all holders of Common Stock entitling them (for a period expiring within 60 days from the date of issuance of such rights or warrants) to subscribe for or
purchase shares of Common Stock at a price per share that is less than the average Sale Prices of a share of Common Stock over the ten consecutive Trading Day period ending on and including the Trading Day immediately preceding the date of
announcement of such issuance, the Base Conversion Rate will be adjusted based on the following formula: 
 

 
 where, 
  

							
		 	CR0	 	=	  	the Base Conversion Rate in effect immediately prior to the Ex Date for such event;
				
		 	CR1	 	=	  	the Base Conversion Rate in effect immediately on and after the Ex Date for such event;
				
		 	OS0	 	=	  	the number of shares of Common Stock outstanding immediately prior to the Ex Date for such event;
				
		 	X	 	=	  	the total number of shares of Common Stock issuable pursuant to such rights or warrants; and
				
		 	Y	 	=	  	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights or warrants divided by the average sale prices of the Common Stock over the 10 consecutive
Trading Day period ending on and including the Trading Day immediately preceding the announcement of such issuance.

  

 30 

 Such adjustment shall be successively made whenever any such rights or warrants are issued and shall
become effective immediately after 9:00 a.m., New York City time, on the Business Day following the Ex Date of such issuance. To the extent that shares of Common Stock are not delivered pursuant to such rights or warrants upon the
expiration or termination of such rights or warrants, the Base Conversion Rate shall be readjusted to the Base 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 actually delivered. In the event that such rights or warrants are not so issued, the Base Conversion Rate shall again be adjusted to be the Base Conversion Rate which would then be in
effect if the announcement with respect to such rights, warrants or convertible securities had not been made. 
 In determining whether any
rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than the average Sale Prices per share of Common Stock over the ten consecutive Trading Day period ending on and including the Trading Day immediately
preceding the date of announcement of such issuance, and in determining the aggregate price payable to exercise such rights or warrants of such shares of Common Stock, there shall be taken into account any consideration received by the Company for
such rights or warrants and any amount payable on exercise thereof, the value of such consideration, if other than cash, to be determined in good faith by the Board of Directors. 
 (iii) In case the Company shall dividend or distribute to all holders of its Common Stock any securities (other than Common Stock),
evidences of indebtedness, assets or properties (excluding (x) any dividend, distribution or issuance covered by clause (i) or (ii) of this Section 4.07(a) and (y) any dividend or distribution paid exclusively in cash) (any
of such shares of capital stock, evidence of indebtedness or assets hereinafter called the “Distributed Property”), then in each such case the Base Conversion Rate shall be adjusted based on the following formula: 
 

 
 where, 
  

							
		 	CR0	  	=	  	the Base Conversion Rate in effect immediately prior to the Ex Date for such distribution;
				
		 	CR1	  	=	  	the Base Conversion Rate in effect immediately on and after the Ex Date for such distribution;

  

 31 

							
		 	  SP0	 	=	  	the Current Market Price of the Common Stock; and
				
		 	FMV	 	=	  	the fair market value (as determined in good faith by the Board of Directors of the Company) of the securities, evidences of indebtedness, assets or property dividended or distributed with
respect to each outstanding share of Common Stock on the Ex Date for such dividend or distribution.

 Such adjustment shall become effective
immediately prior to 9:00 a.m., New York City time, on the Business Day following the Ex Date; provided that if the then fair market value (as so determined) of the portion of the Distributed Property so distributed applicable
to one share of Common Stock is equal to or greater than SP0 as set forth above, in lieu of the foregoing adjustment, adequate provision shall be made so
that each Holder shall have the right to receive, for each $1,000 principal amount of Securities upon conversion, the amount of Distributed Property such Holder would have received had such Holder owned a number of shares of Common Stock equal to
the Conversion Rate on the record date. If such dividend or distribution is not so paid or made, the Base Conversion Rate shall again be adjusted to be the Base Conversion Rate that would then be in effect if such record date had not been fixed. If
the Board of Directors determines the fair market value of any distribution for purposes of this Section 4.07(a)(iii) by reference to the actual or when issued trading market for any securities, it shall in doing so consider the prices in such
market over the same period used in computing the Current Market Price. 
 With respect to an adjustment pursuant to this
clause (iii) where there has been a payment of a dividend or other distribution on the Common Stock or shares of capital stock of, or similar equity interests of, a Subsidiary or other business unit of the Company (a
“Spin-Off”, and any such dividend or distribution of Common Stock, shares of capital stock or equity interests being “Spin-Off Securities”), in which event the Base Conversion Rate will be adjusted based on the
following formula: 
 

 
 where, 
  

							
		 	CR0	 	=	  	the Base Conversion Rate in effect immediately prior to 5:00 p.m. on the 15th Trading Day immediately following, and including, the effective date of the Spin-Off;
				
		 	CR1	 	=	  	the Base Conversion Rate in effect immediately from and after 5:00 p.m. on the 15th Trading Day immediately following, and including, the effective date of the Spin-Off;

  

 32 

							
		 	FMV0	  	=	  	the average of the sale prices of the capital stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock over the 10 consecutive Trading Days
commencing on and including the fifth Trading Day after the effective date of the Spin-Off; and
				
		 	  MP0	  	=	  	the average of the sale prices of the Common Stock over the 10 consecutive Trading Days commencing on and including the fifth Trading Day after the effective date of the
Spin-Off.

 Such adjustment shall occur at the Close of Business on the 10th Trading Day from, and including,
the effective date of the Spin-Off; provided, however, that the Company may in lieu of the foregoing adjustment elect to make adequate provision so that each Holder of Securities shall have the right to receive upon conversion thereof the
amount of such Spin-Off Securities that such Holder of Securities would have received if such Securities had been converted on the record date with respect to such distribution. 
 In the event that the Company has in effect a preferred shares rights plan (“Rights Plan”), upon conversion of the Securities for Common
Stock, to the extent that the Rights Plan is still in effect upon such conversion, the Holders of Securities will receive, in addition to the Common Stock, the rights described therein (whether or not the rights have separated from the Common Stock
at the time of conversion), subject to the limitations set forth in the Rights Plan. If the Rights Plan provides that upon separation of rights under such plan from the Common Stock that the Holders would not be entitled to receive any such rights
in respect of the Common Stock issuable upon conversion for the Securities, the Base Conversion Rate will be adjusted at the time of separation as provided in this Section 4.07(a)(iii) (with such separation deemed to be the distribution of such
rights), subject to readjustment in the event of the expiration, termination or redemption of the rights. Any distribution of rights or warrants pursuant to a Rights Plan that would allow a Holder to receive upon conversion, in addition to the
Common Stock, the rights described therein (whether or not the rights have separated from the Common Stock at the time of conversion), shall not constitute a distribution of rights or warrants pursuant to this Section 4.07. 
 Rights or warrants distributed by the Company to all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of capital
stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”), (i) are deemed to be transferred with such shares of Common Stock,
(ii) are not exercisable and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 4.07 (and no adjustment to the Base Conversion Rate 

  

 33 

 
under this Section 4.07 will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have
been distributed and an appropriate adjustment (if any is required) to the Base Conversion Rate shall be made under this clause (iii) of Section 4.07. If any such right or warrant, including any such existing rights or warrants distributed
prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any
and each such event shall be deemed to be the date of distribution and record date with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders
thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of
calculating a distribution amount for which an adjustment to the Base Conversion Rate under this Section 4.07 was made, (1) in the case of any such rights or warrants which shall all have been repurchased without exercise by any holders
thereof, the Base Conversion Rate shall be readjusted upon such 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 repurchase price received by a holder
or holders of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such repurchase, and (2) in the case of such rights or
warrants which shall have expired or been terminated without exercise by any holders thereof, the Base Conversion Rate shall be readjusted as if such rights and warrants had not been issued. 
 (iv) In case the Company shall, by dividend or otherwise, at any time distribute cash (a “Triggering Distribution”) to
all holders of its Common Stock, the Base Conversion Rate shall be adjusted based on the following formula: 
 

 
 where, 
  

							
		 	CR0	 	=	  	the Base Conversion Rate in effect immediately prior to the Ex Date for such distribution;
				
		 	CR1	 	=	  	the Base Conversion Rate in effect immediately on and after the Ex Date for such distribution;
				
		 	SP0	 	=	  	the Current Market Price of the Common Stock; and
				
		 	 C	 	=	  	the amount in cash per share distributed by the Company to holders of the Common Stock.

  

 34 

 Such adjustment shall become effective immediately
after 5:00 p.m., New York City time, on the Ex Date for such Triggering Distribution; provided that if the portion of the cash so distributed applicable to one share of Common Stock is equal to or greater than SP0 as set forth above, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive, for each $1,000
principal amount upon conversion, the amount of cash such Holder would have received had such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the record date. If such Triggering Distribution is not so paid or made,
the Base Conversion Rate shall again be adjusted to be the Base Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 For the avoidance of doubt, for purposes of this Section 4.07(a)(iv), in the event of any reclassification of the Common Stock, as a result of which
the Securities become convertible into more than one class of Common Stock, if an adjustment to the Base Conversion Rate is required pursuant to this Section 4.07(a)(iv), references in this Section to one share of Common Stock or Current
Market Price of one share of Common Stock shall be deemed to refer to a unit or to the price of a unit consisting of the number of shares of each class of Common Stock into which the Securities are then convertible equal to the numbers of shares of
such class issued in respect of one share of Common Stock in such reclassification. The above provisions of this paragraph shall similarly apply to successive reclassifications. 
 It is expressly understood that a stock buyback, repurchase or similar transaction or program shall in no event be considered a distribution for purposes
of clauses (iii) and (iv) of Section 4.07. 
 (v) In case the Company or one or more of its Subsidiaries shall
purchase any shares of Common Stock by means of a tender offer or exchange offer by the Company or one of its Subsidiaries for the Common Stock (other than Exchange Offers not subject to Rule 13e-4 of the Exchange Act), to the extent that the
cash and value of any other consideration included in the payment per share of Common Stock exceeds the average Sale Prices of a share of Common Stock over the 10 consecutive Trading Days commencing on and including the Trading Day immediately
succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “Expiration Date”), the Base Conversion Rate shall be adjusted based on the following formula: 
  

 35 

 

 
 where, 
  

							
		 	CR0	 	=	  	the Base Conversion Rate in effect at the close of business on the Expiration Date;
				
		 	CR1	 	=	  	the Base Conversion Rate in effect immediately after the Expiration Date;
				
		 	FMV	 	=	  	the fair market value (as determined in good faith by the Board of Directors of the Company) of the aggregate value of all cash and any other consideration paid or payable for shares validly
tendered or exchanged and not withdrawn as of the Expiration Date;
				
		 	OS1	 	=	  	the number of shares of the Common Stock outstanding immediately after the Expiration Date (after giving effect to the purchase or exchange of shares pursuant to such tender or exchange offer);

				
		 	OS0	 	=	  	the number of shares of Common Stock outstanding immediately after the Expiration Date (without giving effect to the purchase or exchange of shares pursuant to such tender or exchange
offer); and
				
		 	SP1	 	=	  	the average of the sale prices a share of Common Stock for the 10 consecutive Trading Days commencing on and including the Trading Day immediately succeeding the Expiration
Date.

 The adjustment to the Base Conversion Rate under this Section 4.07(a)(v) shall occur on the
tenth Trading Day from, and including, the Trading Day next succeeding the date such tender or exchange offer expires. 
 In the event that
the Company is obligated to purchase shares pursuant to any such tender offer, but the Company is permanently prevented by applicable law from effecting any or all such purchases or any or all such purchases are rescinded, the Base Conversion Rate
shall again be adjusted to be the Base Conversion Rate which would have been in effect based upon the number of shares actually purchased. If the application of this clause (v) of Section 4.07(a) to any tender or exchange offer would
result in a decrease in the Base Conversion Rate, no adjustment shall be made for such tender or exchange offer under this Section 4.07(a)(v). 
  

 36 

 (b) No adjustment in the Base Conversion Rate or the Incremental Share Factor shall be made: 

(i) unless such adjustment would require a change of at least 1% in the Base Conversion Rate, provided, however, the Company
shall carry forward any adjustments that are less than 1% of the Base Conversion Rate and take them into account in any subsequent adjustment of the Base Conversion Rate or the Incremental Share Factor or in connection with any conversion of the
Securities; 
 (ii) for any issuance of Common Stock or convertible or exchangeable securities or rights to purchase Common
Stock or convertible of exchangeable securities, except in accordance with Section 4.07(a) above; or 
 (iii) if the
Holders are permitted to participate, without converting their Securities, in the transactions described in clauses (i) through (v) of Section 4.07(a) above that would otherwise require adjustment of the Base Conversion Rate and the
Incremental Share Factor. 
 (c) The Company may, from time to time, and to the extent permitted by law and subject to applicable rules of
the NASDAQ Global Select Market, increase the Conversion Rate by any amount for any period of at least 20 days. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall give notice of the increase to the
Holders in the manner provided in Section 4.09, with a copy to the Trustee and Conversion Agent, at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the
period during which it will be in effect. The Company may also, in its discretion, increase the Conversion Rate, to avoid or diminish any income tax to any holders of shares of Common Stock resulting from any dividend or distribution of stock (or
rights to acquire stock) or from any event treated as such for income tax purposes. 
 Section 4.08. Make-Whole Adjustment.
(a) If a transaction described in clause (a) or (b) of the definition of Change of Control, excluding a Change of Control in clause (b) where the exception relating to a transaction involving consideration of at least 95%
publicly traded securities (a “Make-Whole Fundamental Change”), occurs, and a Holder elects to convert its Securities in connection with such transaction, the Company shall increase the Conversion Rate for the Securities surrendered
for conversion by a number of additional shares of Common Stock (the “Additional Shares”) in accordance with this Section 4.08(a). 
 Any conversion of a Security by a Holder occurring from and after the date that is 15 days prior to the anticipated effective date of the Make-Whole 

  

 37 

 
Fundamental Change through and including the date that is 15 days after the effective date of such Make-Whole Fundamental Change shall be deemed to be in
connection with such Make-Whole Fundamental Change. 
 The Company shall give notice of a Make-Whole Fundamental Change to all record Holders
of the Securities as promptly as practicable following the date the Company makes a public announcement of such Make-Whole Fundamental Change (but in no event less than 15 days prior to the anticipated effective date of such Make-Whole Fundamental
Change). 
 The number of Additional Shares shall be determined by reference to the table below, based on the date the Make-Whole Fundamental
Change occurs or becomes effective (the “Effective Date”) and the price (the “Stock Price”) paid per share of Common Stock in such transaction. If the holders of Common Stock receive only cash in the Make-Whole
Fundamental Change, the Stock Price shall be the cash amount paid per share of Common Stock. Otherwise, the Stock Price shall be the average of the Sale Prices of a share of Common Stock over the 10 consecutive Trading Day period ending on and
including the Trading Day immediately preceding the Effective Date. 
 The following table sets forth the Stock Price and number of
Additional Shares to be received per $1,000 principal amount of Securities:

 The exact Stock Price and effective dates may not be set forth on the table, in which case: 

(i) if the Stock Price is between two Stock Price amounts on the table or the effective date is between two dates on the table, the
number of Additional Shares will be determined by straight-line interpolation between the number of Additional Shares set forth for the higher and lower stock prices and the earlier and later effective dates, as applicable, based on a 365-day year;

 (ii) if the Stock Price is greater than $[            ]
per share (subject to adjustment pursuant to the following paragraph), no increase will be made to the Conversion Rate; and 
 (iii) if the Stock Price is less than $[            ] per share (subject to adjustment pursuant to the following paragraph), no increase will be made to the Conversion Rate.

 The Stock Prices shall be adjusted as of any date on which the Base Conversion Rate of the Securities is adjusted in accordance with
Section 4.07 hereof. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Base Conversion Rate immediately prior to the adjustment giving
rise to the Stock Price adjustment and the denominator of which is the Base Conversion Rate as so adjusted. The number of Additional Shares shall be adjusted in the same manner and for the same events as the Base Conversion Rate as set forth in
Section 4.07 hereof. 
 Notwithstanding the foregoing, in no event shall the total number of Additional Shares of Common Stock added to
the Conversion Rate exceed [            ] per $1,000 principal amount of Securities, subject to adjustments in the same manner as the Base Conversion Rate as set forth in
Section 4.07. 
 (b) If, pursuant to Section 4.08(a), the Company is required to increase the Conversion Rate by the Additional
Shares, Securities surrendered for conversion shall be settled as follows: 
 (i) If the date on which the Securities are surrendered for conversion is prior to the 10th Trading Day preceding the effective date of the
Make-Whole Fundamental Change (the “Cut-off Date”), the Company shall settle such conversion by delivering the number of shares of Common Stock (based on the Conversion Rate without regard to the number of Additional Shares to be
added to the Conversion Rate pursuant to Section 4.08(a)) no later than the third Business Day immediately following the Averaging Period. In addition, as soon as practicable 

  

 39 

 
following the effective date of the Make-Whole Fundamental Change (but in any event within three Trading Days of such effective date), the Company shall
deliver the number of Additional Shares to be added to the Conversion Rate pursuant to Section 4.08(a), if any, or the equivalent of such shares in Reference Property, as applicable. 
 (ii) If the date on which the Securities are surrendered for conversion is on or following the Cut-off Date, the Company shall settle such
conversion (based on the Conversion Rate as increased by the Additional Shares to be added to the Conversion Rate pursuant to Section 4.08(a)) no later than the third Business Day immediately following the Averaging Period, by delivering the
number of shares of Common Stock (based on the Conversion Rate without regard to the number of Additional Shares to be added to the Conversion Rate pursuant to Section 4.08(a)) plus the number of Additional Shares to be added to the Conversion
Rate as set forth in Section 4.08(a), if any, or the equivalent of such shares in Reference Property, as applicable. 
 For the
avoidance of doubt, if Securities are surrendered for conversion in connection with an anticipated Make-Whole Fundamental Change and such Make-Whole Fundamental Change does not in fact occur, no Additional Shares will be added to the Conversion Rate
and no additional cash or Reference Property will be paid as a result of the related anticipated Make-Whole Fundamental Change. 
 Section 4.09. Notice of Adjustment in Base Conversion Rate. Whenever the Base Conversion Rate and Incremental Share Factor are adjusted pursuant to Section 4.07: 
 (a) the Company shall compute the adjusted Base Conversion Rate and Incremental Share Factor in accordance with Section 4.07 and shall prepare an
Officers’ Certificate setting forth (i) the adjusted Base Conversion Rate and Incremental Share Factor, (ii) the clause of Section 4.07 pursuant to which such adjustment has been made, showing in reasonable detail the facts
upon which such adjustment is based, (iii) the calculation of such adjustment and (iv) the date as of which such adjustment is effective, and such certificate shall promptly be filed with the Trustee and with each Conversion
Agent; and 
 (b) upon each such adjustment, a notice stating that the Base Conversion Rate and Incremental Share Factor has been
adjusted and setting forth the adjusted Base 

  

 40 

 
Conversion Rate and Incremental Share Factor shall be required, and as soon as practicable after it is required, such notice shall be provided by the Company
to all Holders of record of the Securities in accordance with Section 12.02. 
 Unless and until a Responsible Officer of the Trustee
shall have received an Officers’ Certificate in accordance with this Section 4.09, the Trustee shall not be deemed to have knowledge of any adjustment of the Base Conversion Rate and Incremental Share Factor and may assume that the last
Base Conversion Rate and Incremental Share Factor of which it has knowledge is still in effect. 
 Neither the Trustee nor any Conversion
Agent shall be under any duty or responsibility with respect to any such certificate or the information and calculations contained therein, except to exhibit the same to any Holder of Securities desiring inspection thereof at its office during
normal business hours. 
 Section 4.10. Effect of Reclassification, Consolidation, Merger or Sale. If any of the following events
occur, namely (i) any recapitalization, reclassification or other similar change in the outstanding shares of Common Stock (other than changes resulting from a subdivision or combination), (ii) any consolidation, merger or combination of
the Company with another Person, (iii) the Company is a party to a statutory share exchange, or (iv) any sale, lease or other conveyance of all or substantially all of the assets of the Company to any other Person, in each case, as a
result of which holders of Common Stock shall be entitled to receive stock, other securities, other property or assets (including cash or any combination thereof) with respect to or in exchange for such Common Stock, the Holders of the Securities
then outstanding will be entitled thereafter to convert such Securities into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that they would have owned or been entitled
to receive (the “Reference Property”) upon such recapitalization, reclassification, change, consolidation, merger, combination, sale, lease, transfer or statutory share exchange had such Securities not been converted into Common
Stock immediately prior to such transaction. 
 In the event the holders of Common Stock have the opportunity to elect the form of
consideration to be received in such transaction, the Company shall make adequate provision whereby the Securities shall be convertible from and after the effective date of such transaction into the form of consideration elected by a majority of the
Company’s stockholders in such transaction. The Company hereby agrees not to become a party to any such transaction unless its terms are consistent with the foregoing. 
  

 41 

 The above provisions of this Section shall similarly apply to successive recapitalizations,
reclassifications, changes, consolidations, mergers, combinations, sales and conveyances. 
 Section 4.11. Taxes on Shares Issued.
The issue of stock certificates on convert for Securities shall be made without charge to the Holder thereof for any documentary, stamp or similar issue or transfer tax in respect of the issue thereof. 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 and delivery of stock in any name other than that of the Holder of any Security converted, and the Company shall not be required to issue or deliver any such
stock certificate unless and until the Person or Persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. 
 Section 4.12. Reservation of Shares, Shares; Listing and Compliance. The Company shall reserve and keep available, free from preemptive
rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for the conversion of Securities from time to time as such Securities are presented for conversion. 
 Before taking any action which would cause an adjustment increasing the Base Conversion Rate to an amount that would cause the Base Conversion Price to
be reduced below the then par value, if any, of the shares of Common Stock issuable upon conversion of the Securities, the Company shall take all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may
validly and legally issue shares of such Common Stock at the Conversion Rate. 
 The Company covenants that all shares of Common Stock which
may be issued upon conversion of Securities will upon issue be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue by the Company thereof, except as set forth in Section 4.11.

 The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Securities hereunder require
registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company will in good faith and as expeditiously as possible, to the extent then permitted by the
rules and interpretations of the SEC (or any successor thereto), endeavor to secure such registration or approval, as the case may be. 
 The
Company further covenants that, if at any time the Common Stock shall be listed on the NASDAQ Global Select Market or any other national securities exchange or automated quotation system, the Company shall, if 

  

 42 

 
permitted by the rules of such exchange or automated quotation system, list and keep listed, so long as the Common Stock shall be so listed on such exchange
or automated quotation system, all Common Stock issuable upon conversion of the Securities. 
 Section 4.13. Responsibility of
Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder of Securities to determine the Conversion Rate or whether any facts exist which may require any adjustment of the
Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and
any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or property, which may at any time be issued or delivered upon the conversion of
any Security; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares
of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Security for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this
Article 4. 
 ARTICLE 5 
 SUBORDINATION 
 Section 5.01. Securities Subordinated to Senior Indebtedness. The Company agrees, and
each Holder by accepting a Security agrees, that the Indebtedness evidenced by the Securities (including the principal of, premium, if any, interest and any Extension Fee on all the Securities and the Fundamental Change Repurchase Price with respect
to all Securities subject to repurchase pursuant to Section 3.08 hereof) is subordinated in right of payment, to the extent and in the manner provided in this Article 5, to the prior payment in full of all Senior Indebtedness (whether
outstanding on the date hereof or hereafter created, incurred, assumed or guaranteed). 
 Section 5.02. Liquidation; Dissolution;
Bankruptcy. In the event of any payment or distribution of assets of the Company upon any dissolution winding up, liquidation or reorganization of the Company, whether in bankruptcy, insolvency, reorganization or receivership proceedings or upon
an assignment for the benefit of creditors or any other marshalling of the assets and liabilities of the Company: 
  

 43 

 (a) holders of Senior Indebtedness shall first be entitled to receive payment in full of all Obligations
due in respect of such Senior Indebtedness (including interest after the commencement of any such proceeding at the rate specified in the applicable Senior Indebtedness) or provision shall be made for such amount in cash, or other payments
satisfactory to the holders of Senior Indebtedness, before Holders of the Securities shall be entitled to receive any payment with respect to the Securities; and 
 (b) until all Obligations with respect to Senior Indebtedness (as provided in paragraph (a) above) are paid in full, any distribution to which Holders would be entitled but for this Article 5 shall be made to
holders of Senior Indebtedness (except that Holders of Securities may receive Permitted Junior Securities), as their interests may appear. 
 Section 5.03. Default on Senior Indebtedness and Designated Senior Indebtedness. 
 (a) The Company may not make any
payment of principal or interest on the Securities to the Trustee or any Holder in respect of Obligations with respect to the Securities if a default in the payment of any principal or other Obligations with respect to Senior Indebtedness occurs, by
reason of acceleration or otherwise, and is continuing beyond any applicable grace period in the agreement, indenture or other document governing such Senior Indebtedness until such default in the payment of all principal and other Obligations with
respect to the Senior Indebtedness has been cured or waived or ceased to exist. 
 (b) During the continuance of any event of default with
respect to any Designated Senior Indebtedness (other than a default in payment of the principal of, premium, if any, or interest on, rent or other payment obligations in respect of any Designated Senior Indebtedness) permitting the holders thereof
to accelerate the maturity thereof (or, in the case of any lease, permitting the landlord either to terminate the lease or to require the Company to make an irrevocable offer to terminate the lease following an event of default under such lease), no
payment may be made by the Company, directly or indirectly, with respect to principal of or interest on the Securities for a period (a “Payment Blockage Period”) commencing upon the receipt by the Trustee of written notice (a
“Payment Blockage Notice”) of such default from persons entitled to give such notice under any agreement pursuant to which that Designated Senior Indebtedness may have been issued, that such an event of default has occurred and is
continuing and ending on the earlier of: (i) 179 days from the date the Trustee shall have received the Payment Blockage Notice, (ii) the date such event of default has been cured or waived or ceases to exist, or (iii) the date such
Payment Blockage Period shall have been terminated by written notice to the Company or the Trustee from the person initiating such Payment Blockage Period. 
  

 44 

 The Company may resume payments on the Securities after the end of the Payment Blockage Period unless the
holders of such Designated Senior Indebtedness or the representative of such holders shall have accelerated the maturity of such Designated Senior Indebtedness. 
 (c) Not more than one Payment Blockage Notice may be given in any consecutive 365-day period, irrespective of the number of defaults with respect to one or more issues of Designated Senior Indebtedness during such
period. No nonpayment default that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Trustee will be, or can be made, the basis for the commencement of a subsequent Payment Blockage Period whether or not within
a period of 365 consecutive days. In no event may the total number of days during which any Payment Blockage Period is in effect exceed 179 days in the aggregate in any consecutive 365-day period. 
 Section 5.04. Acceleration of Securities. If payment of the Securities is accelerated because of an Event of Default, unless the full amount
in respect of all Senior Indebtedness is paid in cash or other payment satisfactory to the holders of Senior Indebtedness, no payment shall be made by the Company with respect to the principal of, or interest on, on the Securities or upon conversion
or repurchase of any of the Securities, and the Company shall promptly notify holders of Senior Indebtedness of the acceleration. 
 Section 5.05. When Distribution Must Be Paid Over. In the event that the Trustee or any Holder receives any payment of any Obligations or distribution of assets of the Company of any kind or character (other than Permitted
Junior Securities pursuant to Article 5 hereof), whether in cash, property or securities (including, without limitation, by way of setoff or otherwise) with respect to the Securities at a time when the Trustee or such Holder, as applicable, has
actual knowledge that such payment is prohibited by Section 5.03 hereof, such payment shall be held by the Trustee or such Holder, in trust for the benefit of, and shall be paid forthwith over and delivered, upon written request, to the holders
of Senior Indebtedness as their interests may appear or their Representative under the indenture or other agreement (if any) pursuant to which Senior Indebtedness may have been issued, as their respective interests may appear, for application to the
payment of all Obligations with respect to Senior Indebtedness remaining unpaid to the extent necessary to pay such Obligations in full in accordance with their terms, after giving effect to any concurrent payment or distribution to or for the
holders of Senior Indebtedness. 
 With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform only such
obligations on the part of the Trustee as are specifically set forth in this Article 5, and no implied covenants or obligations with respect to the holders of Senior Indebtedness shall be read into this Indenture against the Trustee. The Trustee
shall not be deemed to owe any fiduciary duty to the holders 

  

 45 

 
of Senior Indebtedness, and shall not be liable to any such holders if the Trustee shall pay over or distribute to or on behalf of Holders or the Company or
any other Person money or assets to which any holders of Senior Indebtedness shall be entitled by virtue of this Article 5. 
 Section 5.06. Notice by Company. The Company shall promptly notify the Trustee and the Paying Agent of any facts known to the Company that would cause a payment of any Obligations with respect to the Securities to violate this
Article 5, but failure to give such notice shall not affect the subordination of the Securities to the Senior Indebtedness as provided in this Article 5. 
 Section 5.07. Subrogation. After all Senior Indebtedness is paid in full in cash or other payment satisfactory to the holders of the Senior Indebtedness and until the Securities are paid in full,
Securityholders shall be subrogated (equally and ratably with all other Indebtedness pari passu with the Securities and entitled to similar rights of subrogation) to the rights of holders of Senior Indebtedness to receive payments or
distributions applicable to Senior Indebtedness to the extent that payments or distributions otherwise payable to the Securityholders have been applied to the payment of Senior Indebtedness. A distribution made under this Article 5 to holders of
Senior Indebtedness that otherwise would have been made to Securityholders (whether by the Company, any Holder, the Trustee or otherwise) is not, as between the Company and Holders, a payment by the Company on the Securities. 
 Section 5.08. Relative Rights. This Article 5 defines the relative rights of Holders of Securities and holders of Senior Indebtedness.
Nothing in this Indenture shall: 
 (a) impair, as between the Company and Securityholders, the obligation of the Company, which is absolute
and unconditional, to pay principal of, premium, if any, and interest on the Securities in accordance with their terms; 
 (b) affect the
relative rights of Securityholders and creditors of the Company other than their rights in relation to holders of Senior Indebtedness; or 
 (c) prevent the Trustee or any Securityholder from exercising its available remedies upon a Default or Event of Default, subject to the rights of holders and owners of Senior Indebtedness to receive distributions and payments otherwise
payable to Holders of Securities. 
 If the Company fails because of this Article 5 to pay principal of, premium, if any, interest or any
Extension Fee on a Security on the due date, the failure is still a Default or Event of Default. 
  

 46 

 Section 5.09. Subordination May Not Be Impaired by Company. No right of any holder of Senior
Indebtedness to enforce the subordination of the Indebtedness evidenced by the Securities shall be impaired by any act or failure to act by the Company or any Holder or by the failure of the Company or any Holder to comply with this Indenture.

 Section 5.10. Distribution or Notice to Representative. Whenever a distribution is to be made or a notice given to holders of
Senior Indebtedness, the distribution may be made and the notice given to their Representative. Upon any payment or distribution of assets of the Company referred to in this Article 5, the Trustee and the Holders of Securities shall be entitled to
rely upon any order or decree made by any court of competent jurisdiction or upon any certificate of such Representative or of the liquidating trustee or agent or other Person making any distribution to the Trustee or to the Holders of Securities
for the purpose of ascertaining the Persons entitled to participate in such distribution, the holders of the Senior Indebtedness, Designated Senior Indebtedness and other Indebtedness of the Company, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 5. 
 Section 5.11. Rights of Trustee
and Paying Agent. Notwithstanding the provisions of this Article 5 or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts that would prohibit the making of any payment or
distribution by the Trustee, and the Trustee and the Paying Agent may continue to make payments on the Securities, unless the Trustee shall have received at its Corporate Trust Office at least two Business Days prior to the date of such payment
written notice of facts that would cause the payment of any Obligations with respect to the Securities to violate this Article 5. Only the Company, a Representative or a holder of Designated Senior Indebtedness may give the notice. Nothing in this
Article 5 shall impair the claims of, or payments to, the Trustee under or pursuant to Section 9.07 hereof. 
 The Trustee in its
individual or any other capacity may hold Senior Indebtedness with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. 
 Section 5.12. Authorization to Effect Subordination. Each Securityholder, by the Holder’s acceptance thereof, authorizes and directs the Trustee on such Holder’s behalf to take such action as may
be necessary or appropriate to effectuate the subordination as provided in this Article 5, and appoints the Trustee to act as such Holder’s attorney-in-fact for any and all such purposes. If the Trustee does not file a proper proof of claim or
proof of debt in the form required in any proceeding referred to in Section 8.09 hereof at least 30 days before the expiration of the time to file such claim, the holders of any Designated Senior Indebtedness are hereby authorized to file an
appropriate claim for and on behalf of the Securityholders. 
  

 47 

 Section 5.13. Amendments. The provisions of this Article 5 shall not be amended or modified
in any manner adverse to the holders of Senior Indebtedness without the written consent of the holders of all Senior Indebtedness. 
 Section 5.14. Agreement to Subordinate Unaffected. The provisions of this Article 5 shall remain in full force and effect irrespective of (a) any amendment, modification, or supplement of, or any waiver or consent to, any
of the terms of the Senior Indebtedness or the agreement or instrument governing the Senior Indebtedness, (b) the release or non-perfection of any collateral securing the Senior Indebtedness or (c) the manner of sale or other disposition
of the collateral securing the Senior Indebtedness or the application of the proceeds upon such sale. 
 Section 5.15. Certain
Conversions Deemed Payment. For the purposes of this Article 5 only, (a) the issuance and delivery of Permitted Junior Securities upon conversion of Securities in accordance with Article 4 shall not be deemed to constitute a payment or
distribution on account of the principal of, or premium, if any, or interest on the Securities or on account of the purchase or other acquisition of Securities, and (b) the payment, issuance or delivery of cash (except in satisfaction of
fractional shares pursuant to Section 4.06), property or securities (other than Permitted Junior Securities) upon conversion of a Security shall be deemed to constitute payment on account of the principal of such Security. Nothing contained in
this Article 5 or elsewhere in this Indenture or in the Securities is intended to or shall impair, as among the Company, its creditors other than holders of Senior Indebtedness and the Holders, the right, which is absolute and unconditional, of the
Holder of any Security to convert such Security in accordance with Article 4. 
 ARTICLE 6 
 COVENANTS 
 Section 6.01. 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 and this Indenture. Principal, premium, if any, interest,
and any Extension Fee, shall be considered paid on the date it is due if the Paying Agent (if other than the Company or an Affiliate thereof) holds as of 11:00 a.m., New York City time, on the due date money, deposited by the Company or an
Affiliate thereof in immediately available funds, designated for and sufficient to pay all principal, premium, if any, interest and any Extension Fee then due. The Company shall, to the fullest extent permitted by law, pay interest on overdue
principal (including premium, if any), overdue installments of interest and overdue Extension Fees at the rate of 1% above the then-applicable interest rate from the required payment date. 
  

 48 

 Payment of the principal of, premium, if any, interest and any Extension Fee on the Securities shall be
made at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, The City of New York (which shall initially be the office or agency of the Trustee in the Borough of Manhattan, The City of New York);
provided, however, that at the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address appears in the Register; provided further that a beneficial owner
of interests in any Global Security will be paid by wire transfer in immediately available funds in accordance with the Applicable Procedures and a Holder with an aggregate principal amount in excess of $2,000,000 will be paid by wire transfer in
immediately available funds at the election of such Holder if such Holder has provided wire transfer instructions to the Company and the Trustee at least 10 Business Days prior to the payment date. 
 Section 6.02. Reports. The Company shall file all reports and other information and documents that it is required to file with the SEC
pursuant to Section 13 or 15(d) of the Exchange Act, and within 15 days after it files them with the SEC, the Company shall file copies of all such reports, information and other documents with the Trustee; 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 from the SEC. It is agreed that the filing of such reports via the SEC’s EDGAR system shall constitute
“filing” of such reports with the Trustee for purposes of this Section 6.02. The Company shall at all times comply with TIA Section 314(a) and also file with the Trustee and transmit to the Holders such information,
documents and other reports, and such summaries thereof, as may be required pursuant to the TIA at the time and in the manner required by the TIA. 
 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). 
 Section 6.03. Compliance Certificates.  
 (a) The Company shall deliver to the Trustee, within 90 days after the end of each fiscal year, an Officers’ Certificate stating that a review of the activities of the Company and its Subsidiaries during the preceding fiscal year has
been made under the supervision of the signing Officers with a view to determining whether the Company has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such
certificate, that to the best of his or her knowledge, in such Officer’s capacity as an officer of the Company: 
  

 49 

 (i) the Company has kept, observed, performed and fulfilled each and every covenant
contained in this Indenture and is not in default (without regard to grace periods or notice requirements) in the performance or observance of any of the terms, provisions and conditions of this Indenture, or, if a Default or Event of Default shall
have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or proposes to take with respect thereto; and 
 (ii) no event has occurred and remains in existence by reason of which payments on account of the principal of, premium, if any, or
interest on the Securities is prohibited or if such event has occurred, a description of the event and what action the Company is taking or proposes to take with respect thereto. 
 (b) The Company shall, so long as any of the Securities are outstanding, deliver to the Trustee, within five Business Days of any Officer becoming aware
of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto. 
 Section 6.04. Further Instruments and Acts. Upon request of the Trustee, 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 6.05. Maintenance of Corporate Existence. Subject to Article 7, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence. 
 Section 6.06. Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time
insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would prohibit or forgive the Company from paying all or any portion of the principal of, premium, if any,
interest or any Extension Fee on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture, and the Company (to the extent it may lawfully
do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the
execution of every such power as though no such law had been enacted.

 ARTICLE 7 
 CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER OR LEASE 
 Section 7.01. Company May Consolidate, etc., on Certain Terms. The Company shall not directly or indirectly consolidate with or merge into
any other Person or convey, transfer or lease all or substantially all its assets, in a single transaction or a series of transactions, to any Person, unless: 
 (a) the resulting surviving or transferee Person (the “Successor Company”), if not the Company, shall be a corporation organized and existing under the laws of the United States of America, any State
thereof or the District of Columbia and the Successor Company (if not the Company) shall expressly assume, by supplemental indenture, executed and delivered to the Trustee, in form satisfactory to the Trustee, all the obligations of the Company
under the Securities and this Indenture; 
 (b) at the time of and immediately after such transaction, no Event of Default, and no event
which, after notice or lapse of time, would become an Event of Default, shall have happened and be continuing; and 
 (c) an
Officers’ Certificate and an Opinion of Counsel, each stating that the consolidation, merger or conveyance, transfer or lease complies with this Indenture, have been delivered to the Trustee. 
 Notwithstanding the above, certain of the foregoing transactions could constitute a Fundamental Change permitting each Holder to require the Company to
repurchase the Securities of such Holder as set forth in Section 3.08. 
 Section 7.02. Successor Substituted. Upon any
consolidation of the Company with, or merger of the Company into, any other Person or any conveyance, transfer or lease of all or substantially all of the properties and assets of the Company in accordance with Section 7.01, the Successor
Person 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 Person had been named as the Company herein, and thereafter, except in the case of a lease, the predecessor Person shall be relieved of all obligations and covenants under this Indenture and the Securities.

 ARTICLE 8 
 DEFAULT AND REMEDIES 
 Section 8.01. Events of Default.

Security for 30 days after the date when the same becomes due and payable, whether or not such payment is prohibited pursuant to Article 5; 
 (b) the Company defaults in the payment of the principal on any Security when the same becomes due and payable (whether at maturity, on a Fundamental Change Repurchase Date or otherwise), whether or not such payment is prohibited pursuant

to the Trustee and to each Holder as required by Section 3.08; 
 (f) the Company fails to perform or observe any other term, covenant

by the Holders of at least 25% in aggregate principal amount of the Securities then outstanding; 
 (g) a default by the Company or any of
its Subsidiaries in the payment of the principal or interest on any mortgage, agreement or other instrument under which there may be outstanding, or by which there may be secured or evidenced, any debt for money borrowed in excess of
$25.0 million in the aggregate of the Company and/or any of its Subsidiaries, whether such debt now exists or shall hereafter be created, which default results in such debt becoming or being declared due and payable, and such acceleration shall
not have been rescinded or annulled within 30 days after written notice of such acceleration has been received by the Company or any of its Subsidiaries; 
 (h) any judgment or judgments for the payment of $25.0 million or more rendered against the Company or any of its Subsidiaries, which judgment is not waived, discharged or stayed within 60 days after (i) the
date on which the right to appeal thereof has expired if no such appeal has commenced, or (ii) the date on which all rights to appeal have been extinguished; 
  

 52 

 (i) the Company or any Subsidiary of the Company, pursuant to or within the meaning of any Bankruptcy
Law: 
 (i) commences a voluntary case or proceeding; 
 (ii) consents to the entry of an order for relief against it in an involuntary case or proceeding; 
 (iii) consents to the appointment of a Custodian of it or for all or a material portion of its property; or

 (j) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 
 (i) is for relief against the Company or any Subsidiary of the Company in an involuntary case or proceeding; 
 (ii) appoints a Custodian of the Company or any Subsidiary of the Company or for all or a material portion of the property of the Company
or any Subsidiary of the Company; or 
 (iii) orders the liquidation of the Company or any Subsidiary of the Company;

 and in each case the order or decree remains unstayed and in effect for 60 consecutive days. 
 The term “Bankruptcy Law” means Title 11 of the United States Code (or any successor thereto) or any similar federal or state law for
the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator, sequestrator or similar official under any Bankruptcy Law. 
 The Company shall notify the Responsible Officer of the Trustee in writing, promptly upon becoming aware thereof, of any Event of Default by delivering to the Trustee a statement specifying such Event of Default and
any action the Company has taken, is taking or proposes to take with respect thereto. 
 The Trustee shall not be charged with knowledge of
any Event of Default unless written notice thereof shall have been given to a Responsible Officer at the Corporate Trust Office of the Trustee by the Company, a Paying Agent, any Holder or any agent of any Holder. 
  

 53 

 Section 8.02. Acceleration. If an Event of Default (other than an Event of Default specified
in clause (i) or (j) of Section 8.01) occurs with respect to the Company and is continuing, the Trustee may, by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding
may, by notice to the Company and the Trustee, declare the Securities due and payable at their principal amount together with accrued and unpaid interest and any Extension Fees unpaid pursuant to Section 8.03, and the same shall become and be
immediately due and payable. If an Event of Default specified in clause (i) or (j) of Section 8.01 occurs with respect to the Company, all the principal of the Securities and the interest thereon and any Extension Fees unpaid pursuant
to Section 8.03 shall automatically become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders of a majority in aggregate principal amount of the Securities then
outstanding, by written notice to the Company and to the Trustee, may rescind and annul any declaration pursuant to the first sentence of this Section 8.02 and its consequences and such Default shall cease to exist, and any Event of Default
arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon.

 Section 8.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated to,
pursue any available remedy by proceeding at law or in equity to collect the payment of the principal of, or interest 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 it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any 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 to the extent permitted by law. 
 Notwithstanding anything to the contrary in this Indenture, at the election of the Company, the sole remedy for an Event of Default relating to the
failure to file any documents or reports that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act and for any failure to comply with the requirements of Section 314(a)(1) of the TIA or of a
failure to comply with Section 6.02 above (the “Reporting Obligations”), shall for the first 270 days after the occurrence of such an Event of Default consist exclusively of the right to receive an extension fee on the
Securities in an amount equal to 1.00% of the principal amount of the Securities (the “Extension Fee”). If the Company so 

  

 54 

 
elects, the Extension Fee will be payable on all outstanding Securities on the date on which an Event of Default relating to a failure to comply with the
Reporting Obligations first occurs, which will be the 60th day after notice to the Company of its failure to so comply. On the 270th day after such Event of Default (if the Event of Default relating to the Reporting Obligations is not cured or
waived prior to such 270th day), the Securities will be subject to acceleration in accordance with Section 8.02 above. The foregoing shall not affect the rights of Holders in the event of the occurrence of any other Event of Default. In the
event the Company elects not to pay the Extension Fee upon an Event of Default in accordance with this paragraph, the Securities will be subject to acceleration in accordance with Section 8.02 above. 
 Payments of the Fundamental Change Repurchase Price, any Extension Fee, principal of, or premium, if any, and interest on, the Securities that are not
made when due shall accrue interest at the annual rate of 1% above the then-applicable interest rate from the required payment date. 
 Section 8.04. Waiver of Defaults and Events of Default. Subject to Sections 8.07 and 11.02, the Holders of a majority in aggregate principal amount of the Securities then outstanding by notice to the Trustee may waive an
existing default or Event of Default and its consequence, except a default or Event of Default in the payment of the principal of, or premium, if any, interest or any Extension Fee on, any Security, a failure by the Company to convert any Securities
into Common Stock in accordance with the provisions of the Securities and this Indenture or any default or Event of Default in respect of any covenants or provisions of this Indenture or the Securities which, under Section 11.02 cannot be
modified or amended without the consent of the Holder of each Security affected. When a default or Event of Default is waived, it is cured and ceases. 
 Section 8.05. Control by Majority. The Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that the Trustee, in its sole discretion, determines may be unduly
prejudicial to the rights of another Holder or the Trustee, or that may involve the Trustee in personal liability unless the Trustee is offered indemnity satisfactory to it; provided, however, that the Trustee may take any other action
deemed proper by the Trustee which is not inconsistent with such direction. 
 Section 8.06. Limitations on Suits. A Holder may
not pursue any remedy with respect to this Indenture or the Securities (except actions for payment of overdue principal or interest or for the conversion of the Securities pursuant to Article 4) unless: 
 (a) the Holder gives to the Trustee written notice of a continuing Event of Default; 
  

 55 

 (b) the Holders of at least 25% in aggregate principal amount of the then outstanding Securities make a
written request to the Trustee to pursue the remedy; 
 (c) such Holder or Holders offer to the Trustee reasonable 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 the
request and the offer of indemnity; and 
 (e) no direction inconsistent with such written request has been given to the Trustee during
such 60-day period by the Holders of a majority in aggregate principal amount of the Securities then outstanding. 
 A Securityholder may not
use this Indenture to prejudice the rights of another Securityholder or to obtain a preference or priority over such other Securityholder. 
 Section 8.07. Rights of Holders to Receive Payment and to Convert. Notwithstanding any other provision of this Indenture, the right of any Holder of a Security to receive payment of the principal of and interest on the Security,
on or after the respective due dates expressed in the Security and this Indenture, to convert such Security in accordance with Article 4 and 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 without the consent of the Holder. 
 Section 8.08.
Collection Suit by Trustee. If an Event of Default in the payment of principal or interest specified in clause (a) or (b) of Section 8.01 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 of principal and accrued interest remaining unpaid, together with, to the extent that payment of such interest is lawful, interest on overdue principal
and on overdue installments of interest, in each case at the rate per annum borne by the Securities and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel. 
 Section 8.09. Trustee May File Proofs of Claim. The Trustee
may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the 

  

 56 

 
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings
relative to the Company (or any other obligor on the Securities), its creditors or its property and shall be entitled and empowered to collect and receive any money or other property payable or deliverable on any such claims and to distribute the
same, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the
Trustee any amount due to 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 9.07, and to the extent that such payment of the
reasonable compensation, expenses, disbursements and advances in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, money,
securities and other property which the Holders may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee
to authorize or consent to, or, on behalf of any Holder, to authorize, accept or adopt 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. If the Trustee collects any money
pursuant to this Article 8, it shall pay out the money in the following order, subject to the provisions of Article 5: 
 First, to the Trustee for amounts due under Section 9.07; 
 Second, to Holders for amounts due
and unpaid on the Securities for principal, premium, if any, interest, and any Extension Fee, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal, premium, if any, interest,
and any Extension Fee, respectively; and 
 Third, to the Company or such party as a court of competent
jurisdiction shall direct. 
 The Trustee may fix a record date and payment date for any payment to Holders pursuant to this
Section 8.10. 
 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 in the suit of an undertaking to pay the costs of the suit, 

  

 57 

 
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 made by the Trustee, a suit by a Holder pursuant to Section 8.07, or a suit by Holders of more
than 10% in aggregate principal amount of the Securities then outstanding. 
 ARTICLE 9

Duties of Trustee.  
 (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers

 Section 9.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or an Affiliate of the
Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or

direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent (other than the Trustee) and it shall not be responsible for any statement or recital herein or any
statement in the Securities or any other document in connection with the sale of the Securities or pursuant to this Indenture other than its certificate of authentication. 
 Section 9.05. Notice of Default or Events of Default. If a Default or an Event of Default occurs and is continuing and if it is known to the
Trustee, the Trustee shall mail to each Securityholder notice of the Default or Event of Default within 90 days after it occurs. However, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith
determines that withholding notice is in the best interest of Securityholders, except in the case of a Default or an Event of Default in payment of the principal of, premium, if any, or interest on any Security or in the payment of any conversion or
repurchase obligation. 
 Section 9.06. Reports by Trustee to Holders. If such report is required by TIA Section 313, within
60 days after each May 15, beginning with the May 15 following the date of this Indenture, and for so long as Securities remain outstanding, the Trustee shall mail to each Securityholder a brief report dated as of such May 15 that
complies with TIA Section 313(a) (but if no event described in TIA Section 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA
Section 313(b)(2) and (c). 
 A copy of each report at the time of its mailing to Securityholders shall be mailed to the Company and
filed with the SEC and each stock exchange, if any, on which the Securities are listed. The Company shall promptly notify the Trustee whenever the Securities become listed on any stock exchange or listed or admitted to trading on any quotation
system and any changes in the stock exchanges or quotation systems on which the Securities are listed or admitted to trading and of any delisting thereof. 
 Section 9.07. Compensation and Indemnity. The Company shall pay to the Trustee from time to time compensation (as agreed to from time to time by the Company and the Trustee in writing) for its services
(which compensation shall not be limited by any provision of law in regard to the compensation of a trustee 

  

 61 

 
of an express trust). The Company shall reimburse the Trustee promptly upon request for all reasonable disbursements, expenses and advances incurred or made
by it in addition to the compensation for its services. Such expenses may include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel. 
 The Company shall indemnify each of the Trustee and any predecessor Trustee against any and all losses, liabilities, damages, claims or expenses incurred
by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses (including taxes, other than taxes based upon, measured by or determined by the income of the Trustee)
of enforcing this Indenture against the Company (including this Section 9.07) and defending itself against any claim (whether asserted by the Company or any Holder or any other person) or liability in connection with the exercise or performance
of any of its powers or duties hereunder. The Trustee, upon receiving written notice thereof, shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the
Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company
need not pay for any settlement made without its written consent, which consent shall not be unreasonably withheld. 
 The Company need not
reimburse the Trustee for any expense or indemnify it against any loss or liability incurred by it resulting from its negligence or bad faith. 
 To secure the Company’s payment obligations in this Section 9.07, the Trustee shall have a senior claim to which the Securities are hereby made subordinate on all money or property held or collected by the Trustee, except such
money or property held in trust to pay the principal of and interest on the Securities. 
 When the Trustee incurs expenses or renders
services after an Event of Default specified in clause (i) or (j) of Section 8.01 occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute

reason.

 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Immediately after that, the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee
(provided that all sums owing to the Trustee hereunder have been paid) and be released from its obligations (exclusive of any liabilities that the retiring Trustee may have incurred while acting as Trustee) hereunder, 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. A successor Trustee shall mail notice of its succession to each Holder. 

A retiring Trustee shall not be liable for the acts or omissions of any successor Trustee after its succession.

the benefit of the retiring Trustee.

converts into, or transfers all or substantially all of its corporate trust assets (including the administration of this Indenture) to, another corporation, by sale or otherwise, the resulting, surviving or transferee corporation, without any

 (a) either 
 (i) all Securities theretofore authenticated and delivered (other than Securities that have been destroyed, lost or stolen and that have been replaced or paid as provided in Section 2.07) have been delivered to the Trustee for

 64 

 (ii) all such Securities not theretofore delivered to the Trustee for cancellation:

 (A) have become due and payable (whether on the Final Maturity Date, or on any earlier Fundamental Change Repurchase Date,
conversion or otherwise); or 
 (B) will become due and payable at the Final Maturity Date within one year;
 and the Company, in the case of clause (A) or (B) above, has irrevocably deposited or caused to be irrevocably deposited with the Trustee or a Paying Agent
(other than the Company or any of its Affiliates) as trust funds in trust solely for the purpose cash in an amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation,
for principal, premium, if any, and interest to the date of such deposit (in the case of Securities which have become due and payable) or to the Final Maturity Date; 
 (b) the Company has paid or caused to be paid all other sums payable hereunder by the Company, including any unpaid Extension Fees; and

rights, duties and obligations of Securityholders, as beneficiaries hereof with respect to the amounts, if any, so deposited with the Trustee shall survive and (2) the obligations of the Company to the Trustee under Section 9.07 shall
survive and, if money shall have been deposited with the Trustee pursuant to paragraph (b) of this Section 10.01, the provisions of Sections 10.02 and 10.04 shall survive until the Securities have been paid in full. 
 Section 10.02. Application of Trust Money. Subject to the provisions of Section 10.03, the Trustee or a Paying Agent shall hold in
trust, for the benefit of the Holders, all money deposited with it pursuant to Section 10.01 and shall apply the deposited money in accordance with this Indenture and the Securities to the payment of the principal of, premium, if any, and
interest on the Securities and any unpaid Extension Fees; provided that such money need not be segregated from other funds except to the extent required by law. 
  

 65 

 Section 10.03. Repayment to Company. The Trustee and each Paying Agent shall promptly pay to
the Company upon request any excess money (a) deposited with them pursuant to Section 10.01 and (b) held by them at any time. 
 The Trustee and each Paying Agent shall pay to the Company upon request any money held by them for the payment of principal, premium, if any, interest and any Extension Fee that remains unclaimed for two years after a right to such money
has matured; provided, however, that the Trustee or such Paying Agent, before being required to make any such payment, may at the expense of the Company cause to be mailed to each Holder entitled to such money notice that such money
remains unclaimed and that after a date specified therein, which shall be at least 30 days from the date of such mailing, any unclaimed balance of such money then remaining will be repaid to the Company. After payment to the Company, Holders
entitled to money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person. In the absence of a written request from the Company to return unclaimed funds to the Company, the
Trustee shall from time to time deliver all unclaimed funds to or as directed by applicable escheat authorities, as determined by the Trustee in its sole discretion, in accordance with the customary practices and procedures of the Trustee. Any
unclaimed funds held by the Trustee pursuant to this Section 10.03 shall be held uninvested and without any liability for interest. 
 Section 10.04. Reinstatement. If the Trustee or any Paying Agent is unable to apply any money in accordance with Section 10.02 by reason of any legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to
Section 10.01 until such time as the Trustee or such Paying Agent is permitted to apply all such money in accordance with Section 10.02; provided, however, that if the Company has made any payment of the principal of or
interest on any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive any such payment from the money held by the Trustee or such Paying Agent.

 ARTICLE 11 
 AMENDMENTS, SUPPLEMENTS AND WAIVERS 
 Section 11.01. Without

 (a) to cure any ambiguity, defect or inconsistency; 
  

 66 

 (b) to make any other change that does not adversely affect the rights of any Securityholder: 

(c) to provide for uncertificated Securities in addition to or in place of Certificated Securities;

(h) to appoint a successor Trustee; 
 (i)
to provide for the issuance of additional Securities having the same terms as the Securities initially issued hereunder; or

recitation of the text of this Indenture or the Securities as represented by the Company to the Trustee in an Officers’ Certificate. 
 Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 9.02
hereof, the Trustee shall join with the Company in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein
contained, but the Trustee shall not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise. 
 Section 11.02. With Consent of Holders. The Company and the Trustee may amend or supplement this Indenture or the Securities with the written
consent of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding. The Holders of at least a majority in aggregate principal amount of the Securities then outstanding may waive compliance in a particular
instance by the Company with any provision of this Indenture or the 

  

 67 

 
Securities without notice to any Securityholder. However, notwithstanding the foregoing but subject to Section 11.04, without the written consent of
each Securityholder affected, an amendment, supplement or waiver, including a waiver pursuant to Section 8.04, may not: 
 (a) change the
stated maturity of the principal of, or interest on, any Security; 
 (b) reduce the principal amount of, or any premium or interest on, any
Security; 
 (c) reduce the amount of principal payable upon acceleration of the maturity of any Security; 
 (d) change the currency of payment of principal of, or any premium or interest on, any Security; 
 (e) impair the right to institute suit for the enforcement of any payment on, or with respect to, any Security;

 (h) adversely affect the right of Holders to convert Securities other than as provided in or under Article 4 of this Indenture: 
 (i) reduce the percentage of the aggregate principal amount of the outstanding Securities whose Holders must consent to a modification or
amendment; and 
 (j) reduce the percentage of the aggregate principal amount of the outstanding Securities, the consent of whose
holders is necessary to take actions under Sections 8.02, 8.04, 8.05, 8.06 and 9.08 of this Indenture. 
 It shall not be necessary for the
consent of the Holders under this Section 11.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 
 Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental
indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the documents described in Section 12.04 hereof, the 

  

 68 

 
Trustee shall join with the Company in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects
the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture. 
 After an amendment, supplement or waiver under this Section 11.02 becomes effective, the Company shall mail to the Holders affected thereby a notice
briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver. 
 To the extent that the Company or any of the Subsidiaries hold any Securities, such Securities shall be disregarded for purposes of voting in connection
with any notice, waiver, consent or direction requiring the vote or concurrence of Securityholders. 
 Section 11.03. Compliance with
Trust Indenture Act. Every amendment to or supplement of this Indenture or the Securities shall comply with the TIA as in effect at the date of such amendment or supplement. 
 Section 11.04. Revocation and Effect of Consents. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is
a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any
such Holder or subsequent Holder may revoke the consent as to its Security or portion of a Security if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective. 
 After an amendment, supplement or waiver becomes effective, it shall bind every applicable Securityholder. 
 Section 11.05. Notation on or Exchange of Securities. The Trustee may place an appropriate notation about an amendment, supplement or waiver
on any Security thereafter authenticated. The Company in exchange for all Securities may issue and the Trustee shall, upon receipt of a Company Order, authenticate new Securities that reflect the amendment, supplement or waiver. 
 Failure to make the appropriate notation or issue a new Security shall not affect the validity and effect of such amendment, supplement or waiver.

 Section 11.06. Trustee to Sign Amendments, etc. The Trustee shall sign any amendment or supplemental indenture authorized
pursuant to this Article 11 if the amendment or supplemental indenture does not adversely affect the rights, 

  

 69 

 
duties, liabilities or immunities of the Trustee. If it does, the Trustee may, in its sole discretion, but need not sign it. In signing or refusing to sign
such amendment or supplemental indenture, the Trustee shall be provided with and, subject to Section 9.01, shall be fully protected in relying upon in addition to the documents required by Section 12.04, an Officers’ Certificate and
an Opinion of Counsel stating that such amendment or supplemental indenture is authorized or permitted by this Indenture. The Company may not sign an amendment or supplemental indenture until the Board of Directors approves it. 
 Section 11.07. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article, this Indenture shall
be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

immediately available funds in accordance with the rules and procedures of the Depository Trust Company (“DTC”) and a Holder with an aggregate principal amount in excess of $2,000,000 will be paid by wire transfer in immediately

October 15, 2014 (the “Notes”), issued under an Indenture, dated as of September [·], 2007 (together with any amendments
or supplemental indentures thereto, the “Indenture”), between the Company and the Trustee. The terms of this Note include those stated in the Indenture and those required by or made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended, as in effect on the date of the Indenture. This Note is subject to all such terms, and the Holder of this Note is referred to the Indenture and said Act for a statement of them. The Notes are unsecured obligations
of the Company limited to $[·] aggregate principal amount (or $[·] if the Underwriters exercise their option to purchase additional Notes in compliance with the Underwriting Agreement), except that the Company at any time or from time to time may, without the consent of any Holder,
issue additional Notes having the same terms as the Notes initially issued under the Indenture, and entitled to all of the benefits of the Indenture. The Indenture does not limit other debt of the Company, secured or unsecured. 
 5. OPTIONAL REDEMPTION 
 The Company does not have the right
to redeem the Notes. 
 6. REPURCHASE OF NOTES AT OPTION OF HOLDER UPON A FUNDAMENTAL CHANGE 
 Subject to the terms and conditions of the Indenture, if a Fundamental Change occurs, each Holder will, upon receipt of the notice of the occurrence of a
Fundamental Change, have the right to require the Company to repurchase for cash any or all of such Holder’s Notes, or any portion of those Securities that is equal to $1,000 or an integral multiple of $1,000, on the date that is 45 days after
the Fundamental Change Repurchase Notice at a price equal to 100% of the principal amount of the Notes to be repurchased plus accrued and unpaid interest, if any, to (but excluding) the Fundamental Change Repurchase Date. 
 Holders have the right to withdraw any Fundamental Change repurchase notice, in whole or in part, by delivering to the Paying Agent a written notice of
withdrawal in accordance with the provisions of the Indenture. 
 If cash sufficient to pay the Fundamental Change Repurchase Price of all
Notes or portions thereof to be purchased as of the Fundamental Change 

  

 A-5 

 
Repurchase Date, has been deposited with the Paying Agent on or prior to the Business Day following the Fundamental Change Repurchase Date, all interest
shall cease to accrue on such Notes (or portions thereof) immediately after such Fundamental Change Repurchase Date and the Holder thereof shall have no other rights as such other than the right to receive the Fundamental Change Repurchase Price,
upon surrender of such Notes. 
 7. CONVERSION 
 A Holder of a Note may convert the principal amount of such Note (or any portion thereof equal to $ 1,000 or any integral multiple of $1,000 in excess thereof) into Common Stock at any time prior to the Close of Business on the Business Day
immediately preceding the Final Maturity Date, at the Conversion Rate in effect on the Conversion Date; provided, however, that, if such Note is submitted or presented for repurchase pursuant to Article 3 of the Indenture, such
conversion right shall terminate at the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date for such Note or such earlier date as the Holder presents such Note for repurchase (unless the Company shall
default in making the Fundamental Change Repurchase Price payment when due, in which case the conversion right shall terminate at the close of business on the date such default is cured and such Note is repurchased). 
 The Conversion Rate will be determined in accordance with Section 4.02 of the Indenture. 
 Upon surrender of Notes for conversion, the Company shall deliver shares of Common Stock in the amounts provided in Section 4.04 of the Indenture.

 No fractional shares will be issued upon conversion; in lieu thereof, an amount will be paid in cash based upon the Sale Price of the
Common Stock on the Trading Day immediately prior to the Conversion Date. 
 To convert a Note, a Holder must follow the procedures set forth
in the Indenture. 
 A Note in respect of which a Holder had delivered a Fundamental Change Repurchase Notice exercising the option of such
Holder to require the Company to purchase such Note may be converted only if the Fundamental Change Repurchase Notice is withdrawn in accordance with the terms of the Indenture. 
 8. DENOMINATIONS, TRANSFER, EXCHANGE 
 The Notes are in registered form, without coupons, in denominations of
$1,000 and integral multiples of $1,000. A Holder may register the transfer of or exchange Notes in accordance with the Indenture. The Registrar may require a 

  

 A-6 

 
Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes or other governmental charges that may be imposed
in relation thereto by law or permitted by the Indenture. 
 9. PERSONS DEEMED OWNERS 
 The Holder of a Note may be treated as the owner of it for all purposes. 
 10. UNCLAIMED MONEY 
 The Trustee and each Paying Agent shall pay to the Company upon request any money held
by them for the payment of principal or interest that remains unclaimed for two years after a right to such money has matured. After payment to the Company, Holders entitled to money must look to the Company for payment as general creditors unless
an applicable abandoned property law designates another person. 
 11. AMENDMENT, SUPPLEMENT AND WAIVER 
 Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in
aggregate principal amount of the Notes then outstanding, and an existing default or Event of Default and its consequence or compliance with any provision of the Indenture or the Notes may be waived in a particular instance with the consent of the
Holders of a majority in aggregate principal amount of the Notes then outstanding. Without the consent of or notice to any Holder, the Company and the Trustee may amend or supplement the Indenture or the Notes to, among other things, cure any
ambiguity, defect or inconsistency or make any other change that does not adversely affect the rights of any Holder. 
 12. SUCCESSOR ENTITY 
 When a successor corporation assumes all the obligations of its predecessor under the Notes and the Indenture in accordance with the terms and conditions
of the Indenture, the predecessor corporation (except in certain circumstances specified in the Indenture) shall be released from those obligations. 
 13.
DEFAULTS AND REMEDIES 
 The definition of Event of Default is in the Indenture. If an Event of Default (other than as a result of certain
events of bankruptcy, insolvency or reorganization of the Company) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding may declare the Notes due and immediately payable at
their principal amount together with accrued and unpaid interest, all as and to the extent provided in the Indenture. If an Event of Default occurs as a result of certain 

  

 A-7 

 
events of bankruptcy, insolvency or reorganization of the Company, all the principal of the Notes and the interest thereon shall become immediately due and
payable 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. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may
require indemnity satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Notes then outstanding may direct the Trustee in its exercise of any trust
or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal or interest) if it determines that withholding notice is in their interests. The Company is required to file periodic reports
with the Trustee as to the absence of default. 
 14. TRUSTEE DEALINGS WITH THE COMPANY 
 U.S. Bank National Association, a national banking association, the Trustee under the Indenture, in its individual or any other capacity, may make loans
to, accept deposits from and perform services for the Company or an Affiliate of the Company, and may otherwise deal with the Company or an Affiliate of the Company, as if it were not the Trustee. 
 15. NO RECOURSE AGAINST OTHERS 
 No past, present or future
director, officer, employee, incorporator or stockholder of the Company, as such, shall have any liability for any obligations of the Company under the Notes, the Indenture or for any claim based on, in respect of, or by reason of, such obligations
or their creation. The Holder of this Note by accepting this Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of this Note. 
 16. AUTHENTICATION 
 This Note shall not be valid until the
Trustee or an authenticating agent manually signs the certificate of authentication on the other side of this Note. 
 17. ABBREVIATIONS AND DEFINITIONS

 Customary abbreviations may be used in the name of the Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by
the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian) and UGMA (= Uniform Gifts to Minors Act).

 18. RANK

Company. Each Holder of this Note, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on such Holder’s behalf to take such action as may be necessary or appropriate to
effectuate the subordination so provided and (c) appoints the Trustee such Holder’s attorney-in-fact for any and all such purposes.

below), the Required Lenders signatory hereto, UBS AG, STAMFORD BRANCH, as administrative collateral agent and as administrative agent (in its capacity as administrative agent, the “Administrative Agent”) for the Lenders, and GMAC

 WHEREAS, Borrower, Guarantors, the Administrative Agent, the Collateral Agent, the other Agents and the
Lenders entered into that certain Credit Agreement dated as of March 20, 2006 (as amended, supplemented, restated or otherwise modified from time to time, the “Credit Agreement”); and 
 WHEREAS, Borrower has requested that Agents and the Required Lenders amend certain provisions of the Credit Agreement, all upon the terms and subject to
the conditions as herein set forth; 
 NOW THEREFORE, in consideration of the foregoing recitals and mutual agreements contained herein and
for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Agents, Required Lenders, Borrower and the other Loan Parties agree as follows: 
 SECTION 1. Amendments. The Credit Agreement is hereby amended as follows: 
 (a) Clause (g) of the definition of the term “Borrowing Base” is hereby amended and restated in its entirety to read as follows:

 “(g) $9,000,000 (except that such amount shall be $6,000,000 in fiscal months October and November);” 

(b) Section 1.01 is hereby amended by adding the following defined term in alphabetical order therein: 
 “First Amendment Effective Date” means the date on which the conditions to effectiveness of the First Amendment to Credit Agreement, by
and among, Borrower, Guarantors, Agents and Required Lenders have been met by the Borrower and Guarantors. 
 (c) Section 5.01(h)
is hereby amended and restated in its entirety to read as follows: 
 “(h) Budgets. Within forty-five
(45) days after the first day of each fiscal year of Holdings, a budget in form reasonably satisfactory to the Administrative Agent (including budgeted statements of income by each of Holdings’ business units and 

 
sources and uses of cash and balance sheets and Borrowing Base levels and credit utilization) prepared by Holdings for (i) each fiscal month of the
current or subsequent, as applicable, fiscal year prepared in detail and (ii) each of the three years immediately following such current or subsequent, as applicable, fiscal year prepared in summary form, in each case, of Holdings and its
Subsidiaries, with appropriate presentation and discussion of the principal assumptions upon which such budgets are based, accompanied by the statement of a Financial Officer of Holdings to the effect that the budget of Holdings is a reasonable
estimate for the period covered thereby;” 
 (d) Section 6.08(b) is hereby amended and restated in its entirety to read as
follows: 
 “(b) Limitation on Capital Expenditures. Permit the aggregate amount of Capital Expenditures made in any fiscal year
set forth in the table below to exceed the amount set forth opposite such fiscal year: 
  

				
	 Fiscal Year
	  	Amount
	 Fiscal year 2006
	  	$	21.0 million
	 Fiscal year 2007
	  	$	23.0 million
	 Fiscal year 2008

permitted in clause (b) above for such fiscal year (before giving effect to any carryover), then 50% of the shortfall may be added to the amount of Capital Expenditures permitted in clause (b) above for the immediately
succeeding (but not any other) fiscal year if the amount expended in such fiscal year would not exceed 150% of the amount permitted for such fiscal year (before any carryover and excluding any Hebron Capital Expenditures) and (y) in determining
whether any amount is available for carryover, the amount expended in any fiscal year shall first be deemed to be from the amount allocated to such year before any carryover; provided, further, notwithstanding the limitations set forth
above, the Loan Parties are permitted to incur up to $14,500,000 in the aggregate of additional Capital Expenditures on and after the First Amendment Effective Date to increase their manufacturing capacity and infrastructure at their facility
located in Hebron, Ohio (the “Hebron Facility Project”). Capital Expenditures made with the proceeds of casualty insurance or condemnation awards to repair or replace the property with respect to which such proceeds were paid shall
not reduce the amount of capital expenditures otherwise permitted pursuant to this Section 6.08(b).”

satisfaction of the following conditions precedent:

of Default or Default shall exist on the date hereof. 
 SECTION 3. Representations and Warranties of Loan Parties.

 (a) The execution, delivery and performance by each Loan Party of this Amendment has been duly authorized by all necessary corporate action
and this Amendment is a legal, valid and binding obligation of such Loan Party enforceable against such Loan Party in accordance with its terms, except as the enforcement thereof may be subject to (i) the effect of any applicable bankruptcy,
insolvency, reorganization, moratorium or similar law affecting creditors’ rights generally and (ii) general principles of equity (regardless of whether such enforcement is sought in a proceeding in equity or at law); 
 (b) Each of the representations and warranties of the Loan Parties contained in the Credit Agreement is true and correct in all material respects on and
as of the date hereof as if made on the date hereof, except to the extent that such representations and warranties expressly relate to an earlier date; and 
 (c) Neither the execution, delivery and performance of this Amendment by each Loan Party nor the consummation of the transactions contemplated hereby does or will contravene, result in a breach of, or violate
(i) any provision of such Loan Party’s certificate or articles of incorporation or bylaws, (ii) any law or regulation, or any order or decree of any court or government instrumentality, in each case, applicable to any Loan Party or
its assets, or (iii) any indenture, mortgage, deed of trust, lease, agreement or other instrument to which such Loan Party or any of its Subsidiaries is a party or by which such Loan Party or any of its Subsidiaries or any of their property is

 3

“herein” or words of similar import shall mean and be a reference to the Credit Agreement as amended hereby. 
 (c) Each Loan Party
acknowledges and agrees that the execution and delivery by Agents party hereto and Required Lenders of this Amendment shall not be deemed (i) to create a course of dealing or otherwise obligate any Agent or any Lender to forbear, waive, consent
or execute similar amendments under the same or similar circumstances in the future, or (ii) to amend, relinquish or impair any right of any Agent or any Lender to receive any indemnity or similar payment from any Person or entity as a result
of any matter arising from or relating to this Amendment. 
 (d) Each Loan Party affirms and acknowledges that this Amendment constitutes a
Loan Document under the Credit Agreement and any reference to the Loan Documents under the Credit Agreement contained in any notice, request, certificate or other document executed concurrently with or after the execution and delivery of this
Amendment shall be deemed to include this Amendment unless the context shall otherwise specify.

Expenses. As provided in Section 11.03 of the Credit Agreement, Borrower agrees to reimburse Agents for all reasonable out-of-pocket fees, costs and expenses, including the fees, costs and expenses of counsel or other advisors
for advice, assistance, or other representation in connection with this Amendment.

of counterparts, each of which when so executed shall be deemed an original, but all such counterparts shall constitute one and the same instrument. In the event that any signature is delivered by facsimile transmission, such signature shall create
a valid and binding obligation of the party executing (or on whose behalf the signatory is executing) the same with the same force and effect as if such facsimile signature page were an original thereof, and such party shall promptly follow its
facsimile signature page by delivery of a hard copy original.
