 provided, that ABL Priority Collateral shall not include any identifiable proceeds of any Notes Priority Collateral.

Article II 
 THE NOTES

 Section 2.1 Form and Dating. The Notes shall be substantially in the form of Exhibit A
attached hereto. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note shall be dated the date of its authentication. The Notes will be issued in registered form, without coupons, and in
minimum denominations of $1.00 and integral multiples of $1.00 in excess thereof. The registered Holder will be treated as the owner of such Note for all purposes. 

The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Indenture, and the Issuer 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 Note conflicts with the express provisions of this Indenture, the
provisions of this Indenture shall govern and be controlling. 
 The Notes shall be issued initially in the form of one or more Global
Notes, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Note Custodian, and registered in the name of the Depositary or a nominee of the Depositary, duly executed by the Issuer and authenticated by the
Trustee as hereinafter provided. 
 Each Global Note shall represent such of the outstanding Notes as shall be specified therein, and each
shall provide that it shall represent the aggregate amount of outstanding Notes from time to time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate,
to reflect exchanges, redemptions, transfers of interests and the payment of PIK Interest. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the
Trustee or the Note Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.6 or by the Issuers in connection with a PIK Payment. 

The Issuer shall execute and the Trustee shall, in accordance with this Section 2.1 and Section 2.2, authenticate and deliver the
Global Notes that (a) shall be registered in the name of the Depositary or the nominee of the Depositary and (b) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary’s instructions or held by the Note
Custodian for the Depositary. 

  
 38 

 Section 2.2 Execution and Authentication. An Officer
shall sign the Notes for the Issuer by manual or facsimile signature. 
 If an Officer whose signature is on a Note no longer holds that
office at the time a Note is authenticated, the Note shall nevertheless be valid. 
 A Note shall not be valid until authenticated by the
manual signature of a Responsible Officer of the Trustee. The signature of a Responsible Officer of the Trustee shall be conclusive evidence that the Note has been authenticated under this Indenture. 

The Trustee shall, upon receipt of a written order of the Issuer signed by one Officer directing the Trustee to authenticate the Notes and
certifying that all conditions precedent to the issuance of the Notes contained herein have been complied with and receipt of an Opinion of Counsel, authenticate Notes for original issue in the aggregate principal amount stated in such written
order. 
 The Trustee may appoint an authenticating agent reasonably acceptable to the Issuer to authenticate Notes. Unless limited by the
terms of such appointment, an authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent or agents. An authenticating agent has
the same rights as an Agent to deal with Holders or the Issuer or an Affiliate of the Issuer. 
 Notwithstanding anything to the contrary
herein, no Officers’ Certificate or Opinion of Counsel shall be required to be delivered in connection with a payment of PIK Interest (whether by an issuance of PIK Interest Notes or by an increase in Global Notes reflecting a PIK Payment).

 Section 2.3 Registrar; Paying Agent. The Issuer shall maintain (a) an office or agency where
Notes may be presented for registration of transfer or for exchange (“Registrar”) and (b) an office or agency where Notes may be presented for payment to a Paying Agent. The Registrar shall keep a register of the Notes and of
their transfer and exchange. The Issuer may appoint one or more co-registrars and one or more additional Paying Agents. The term “Registrar” includes any
co-registrar, and the term “Paying Agent” includes any additional Paying Agent. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer and/or any Subsidiary may
act as Paying Agent or Registrar. 
 The Issuer shall notify the Trustee in writing, and the Trustee shall notify the Holders, of the name
and address of any Agent not a party to this Indenture. The Issuer shall enter into an appropriate agency agreement with any Agent not a party to this Indenture, which shall incorporate the relevant provisions of the TIA that relate to such Agent.
If the Issuer fails to appoint or maintain a Registrar or Paying Agent, or fails to give the foregoing notice, the Trustee shall act as such, and shall be entitled to appropriate compensation in accordance with Section 7.7. 

  
 39 

 The Issuer initially appoints the Trustee to act as the Registrar, Paying Agent and
Conversion Agent, at its Corporate Trust Office. 
 The Issuer initially appoints DTC to act as the Depositary with respect to the Global
Notes. 
 Section 2.4 Paying Agent to Hold Money in Trust. The Issuer shall require each Paying
Agent other than the Trustee to agree in writing that the Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium (including the Applicable Premium and
Redemption Premium) or interest on the Notes, and shall notify the Trustee of any Default by the Issuer in making any such payment. While any such Default continues, the Trustee may require a Paying Agent to pay to the Trustee all money held by it
in trust for the benefit of the Holders or the Trustee. The Issuer at any time may require a Paying Agent to pay all money held by it in trust for the benefit of the Holders or the Trustee to the Trustee. Upon payment over to the Trustee, the Paying
Agent (if other than the Issuer or any of its Subsidiaries) shall have no further liability for such money. If the Issuer or any of its Subsidiaries acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the
Holders all money held by it as Paying Agent. Upon the occurrence of any of the events specified in Section 6.1, the Trustee shall serve as Paying Agent for the Notes. 

Section 2.5 Holder 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 all Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Issuer shall furnish to the Trustee at least seven (7) Business Days
before each 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 the Holders, including the aggregate
principal amount of the Notes held by each Holder thereof, and the Issuer shall otherwise comply with TIA § 312(a). 

Section 2.6 Book-Entry Provisions for Global Notes. (a) Each Global Note shall (a) be
registered in the name of the Depositary for such Global Notes or the nominee of such Depositary, (b) be delivered by the Trustee to the Depositary or pursuant to the Depositary’s instructions or held by the Note Custodian for the
Depositary and (c) bear the Global Note legends as required by Section 2.6(e). 
 Members of, or Participants in, the Depositary
shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary, or the Note Custodian, or under such Global Note, and the Depositary may be treated by the Issuer, and the Trustee or any Agent and any
of their respective agents, as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Trustee or any Agent or their respective agents from giving effect to any
written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Participants, the operation of customary practices governing the exercise of the rights of an owner of a beneficial interest
in any Global Note. 

  
 40 

 Neither the Trustee nor any Agent shall have any responsibility or obligation to any Holder
that is a member of (or a Participant in) the Depositary or any other Person with respect to the accuracy of the records of the Depositary (or its nominee) or of any member or Participant thereof, with respect to any ownership interest in the Notes
or with respect to the delivery of any notice (including any notice of redemption) or the payment of any amount or delivery of any Notes (or other security or property) under or with respect to the Notes. The Trustee and any Agent may rely (and
shall be fully protected in relying) upon information furnished by the Depositary with respect to its members, Participants and any beneficial owners in the Notes. 

Neither the Trustee nor any Agent shall have any responsibility for any actions taken or not taken by the Depositary. 

(a) Transfers of a Global Note shall be limited to transfers of such Global Note in whole, but not in part, to the Depositary,
its successors or their respective nominees. Interests of beneficial owners in a Global Note may be transferred in accordance with the rules and procedures of the Depositary. In addition, certificated Notes shall be transferred to beneficial owners
in exchange for their beneficial interests only if (1) the Depositary notifies the Issuer that it is unwilling or unable to continue as Depositary for the Global Notes or the Depositary ceases to be a “clearing agency” registered
under the Exchange Act and, in each case, a successor depositary is not appointed by the Issuer within 90 days of such notice or (2) an Event of Default of which a Responsible Officer of the Trustee has notice or knowledge as provided in
Section 7.2(j) has occurred and is continuing and the Registrar has received a request from any Holder of a Global Note to issue such certificated Notes. 

(b) In connection with the transfer of an entire Global Note to beneficial owners pursuant to Section 2.6(a), such Global
Note shall be deemed to be surrendered to the Trustee for cancellation, and the Issuer shall execute, and the Trustee shall authenticate and deliver to each beneficial owner identified by the Depositary in exchange for its beneficial interest in
such Global Note an equal aggregate principal amount of certificated Notes of authorized denominations. 
 (c) The registered
Holder of a Global Note may grant proxies and otherwise authorize any Person, including Participants and Persons that may hold interests through Participants, to take any action which a Holder is entitled to take under this Indenture or the Notes.

 (d) Each Global Note shall bear the Global Note Legend on the face thereof. 

(e) At such time as all beneficial interests in Global Notes have been exchanged for certificated Notes, redeemed, repurchased
or cancelled, all Global Notes shall be returned to or retained and cancelled by the Trustee in accordance with Section 2.11. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for certificated
Notes, redeemed, repurchased or cancelled, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note, by the Trustee or the Note Custodian, at the direction of the
Trustee, to reflect such reduction. 

  
 41 

 (f) General Provisions Relating to Transfers and Exchanges. 

(1) To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Global
Notes and certificated Notes at the Registrar’s request. 
 (2) No service charge shall be made to a Holder for any
registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any stamp or transfer tax or similar governmental charge payable in connection therewith (other than any such stamp or transfer taxes or similar
governmental charge payable upon exchange or transfer pursuant to Section 2.6(h), Section 2.10, Section 3.6, Section 4.10, Section 4.13, Section 9.5, Section 12.1 and Section 12.2). 

(3) All Global Notes and certificated Notes issued upon any registration of transfer or exchange of Global Notes or
certificated Notes shall be the valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes (or interests therein) or certificated Notes surrendered upon such registration of
transfer or exchange. 
 (4) The Registrar is not required (A) to issue, to register the transfer of or to exchange
Notes during a period beginning at the opening of 15 days before the day of any selection of Notes for redemption and ending at the close of business on the day of such selection, (B) to register the transfer of or to exchange any Note so
selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part, or (C) to register the transfer of or to exchange a Note between a record date and the next succeeding Interest Payment Date. 

(5) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Issuer may deem and
treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent, or the Issuer
shall be affected by notice to the contrary. 
 (6) The Trustee shall authenticate Global Notes and certificated Notes in
accordance with the provisions of Section 2.2. Except as provided in Section 2.6(b), neither the Trustee nor the Registrar shall authenticate or deliver any certificated Note in exchange for a Global Note. 

(7) Each Holder agrees to indemnify the Issuer and the Trustee against any liability that may result from the transfer,
exchange or assignment of such Holder’s Note in violation of any provision of this Indenture and/or applicable United States federal or state securities law. 

  
 42 

 (8) Neither the Trustee nor any Agent shall have any 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 Note (including any transfers between or among Participants or
beneficial owners of interests in any Global Note) 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. 
 (g) Each Note
shall bear the OID Legend on the face thereof. 
 Section 2.7 Replacement Notes. If any mutilated
Note is surrendered to the Trustee, or the Issuer and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Note, the Issuer shall issue and the Trustee, upon the written order of the Issuer signed by an Officer
of the Issuer, shall authenticate a replacement Note if the Trustee’s requirements are met. An indemnity bond must be supplied by the Holder that is sufficient in the judgment of each of the Trustee and the Issuer to protect each of the Issuer,
the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuer, the Trustee and the Agents may charge for their expenses in replacing a Note. 

Every replacement Note is an additional obligation of the Issuer and shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Notes duly issued hereunder. 
 Section 2.8 Outstanding Notes. The
Notes outstanding at any time are all the Notes authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the
provisions hereof, and those described in this Section 2.8 as not outstanding. Except as set forth in Section 2.9, a Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note. 

For the avoidance of doubt, the aggregate principal amount outstanding under any Note shall include any increase in the outstanding principal
amount in Global Notes as the result of the payment of PIK Interest. 
 If a Note is replaced pursuant to Section 2.7, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser. 
 If the Paying
Agent (other than the Issuer, a Subsidiary or an Affiliate of any thereof) holds, on any payment date, money sufficient to pay the amounts under the Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer
outstanding and shall cease to accrue interest. 

  
 43 

 Section 2.9 Treasury Notes. In determining whether
the Holders of the required aggregate principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer or by any Affiliate of the Issuer shall be considered as though not outstanding, except that for the
purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes of which a Responsible Officer of the Trustee has written notice as being so owned shall be so disregarded.
Notwithstanding the foregoing, Notes that are to be acquired by the Issuer or an Affiliate of the Issuer pursuant to an exchange offer, tender offer or other agreement shall not be deemed to be owned by such entity until legal title to such Notes
passes to such entity. 
 Section 2.10 Temporary Notes. Until certificated Notes are ready for
delivery, the Issuer may prepare and the Trustee shall authenticate temporary Notes upon a written order of the Issuer signed by one Officer of the Issuer. Temporary Notes shall be substantially in the form of certificated Notes but may have
variations that the Issuer considers appropriate for temporary Notes. Without unreasonable delay, the Issuer shall prepare and the Trustee shall upon receipt of a written order of the Issuer signed by one Officer, authenticate certificated Notes in
certificate form in exchange for temporary Notes. 
 Holders of temporary Notes shall be entitled to all of the benefits of this Indenture.

 Section 2.11 Cancellation. The Issuer at any time may deliver to the Trustee for cancellation any
Notes previously authenticated and delivered hereunder or which the Issuer may have acquired in any manner whatsoever, and all Notes so delivered shall be promptly cancelled by the Trustee. All Notes surrendered for registration of transfer,
exchange or payment, if surrendered to any Person other than the Trustee, shall be delivered to the Trustee. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation.
Subject to Section 2.7, the Issuer may not issue new Notes to replace Notes that it has redeemed or paid or that have been delivered to the Trustee for cancellation. All cancelled Notes held by the Trustee shall be disposed of in accordance
with its customary practice, and certification of their disposal delivered to the Issuer upon its written request therefor. 

Section 2.12 Defaulted Interest. If the Issuer defaults in a payment of interest on the Notes, it
shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, which date shall be the earliest practicable date but
in all events at least five (5) Business Days prior to the payment date, in each case at the rate provided in the Notes and in Section 4.1. The Issuer shall fix or cause to be fixed each such special record date and payment date and shall
promptly thereafter notify the Trustee of any such date. At least 15 days before the special record date, the Issuer (or the Trustee, in the name and at the expense of the Issuer) shall mail or cause to be mailed to Holders a notice that states the
special record date, the related payment date and the amount of such interest to be paid. 
 Section 2.13
Computation of Interest. Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months. 

Section 2.14 CUSIP Number. The Issuer in issuing the Notes may use a “CUSIP” number, and if
it does so, the Trustee shall use the CUSIP number in notices of redemption or exchange as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number
printed in the notice or on the Notes and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption or exchange shall not be affected by any defect in or omission of such numbers. The Issuer
shall promptly notify the Trustee in writing of any change in any CUSIP number. 

  
 44 

 Section 2.15 Issuance of Additional Notes. The
Issuer shall be entitled to issue Additional Notes in an unlimited aggregate principal amount under this Indenture that shall have identical terms as the Initial Notes, other than with respect to the date of issuance, issue price, amount of interest
payable on the first Interest Payment Date applicable thereto, transfer restrictions, any registration rights agreement and additional interest with respect thereto; provided that such issuance is not prohibited by the terms of this
Indenture, including Section 4.9. The Initial Notes and any Additional Notes or PIK Interest Notes (including any increases in Global Notes reflecting a PIK Payment) shall be treated as a single class for all purposes under this Indenture. 

With respect to any Additional Notes, the Issuer shall set forth in an Officers’ Certificate, a copy of which shall be delivered to the
Trustee, the following information: 
 (1) the aggregate principal amount of such Additional Notes to be authenticated and
delivered pursuant to this Indenture; 
 (2) the issue price, the issue date, the CUSIP number of such Additional Notes, the
first Interest Payment Date and the amount of interest payable on such first Interest Payment Date applicable thereto and the date from which interest shall accrue; and 

(3) that such issuance is not prohibited by this Indenture. 

The Trustee shall, upon receipt of the Officers’ Certificate, authenticate the Additional Notes in accordance with the provisions of
Section 2.2 of this Indenture. 
 Section 2.16 Payment of PIK Interest. On any Interest Payment
Date on which the Issuer pays PIK Interest (a “PIK Payment”), with respect to a Global Note, the Trustee, or the Note Custodian at the direction of the Trustee, will increase the principal amount of such Global Note by an amount
equal to the PIK Interest payable, rounded down to the nearest whole dollar, for the relevant interest period on the principal amount of such Global Note, to the credit of the Holders on the relevant record date and an adjustment will be made on the
books and records of the Trustee with respect to such Global Note to reflect such increase. On any Interest Payment Date on which the Issuer makes a PIK Payment by issuing Definitive Notes (a “PIK Interest Note”) under this
Indenture having the same terms as the Notes, the principal amount of any such PIK Interest Note issued to any Holder, for the relevant interest period as of the relevant record date for such Interest Payment Date, will be rounded down to the
nearest whole dollar. 
 Article III 

REDEMPTION AND PREPAYMENT 

Section 3.1 Notices to Trustee. If the Issuer elects to redeem Notes pursuant to the optional
redemption provisions of Section 3.7, it shall furnish to the Trustee, at least five Business Days (or such shorter period as is acceptable to the Trustee) before sending a notice of such redemption, an Officers’ Certificate setting forth
the (a) section of this Indenture pursuant to which the redemption shall occur, (b) redemption date and (c) principal amount of Notes to be redeemed. 

  
 45 

 Section 3.2 Selection of Notes to Be Redeemed. In
the event that less than all of the Notes are to be redeemed at any time, the Trustee shall select the Notes to be redeemed among the Holders in compliance with the requirements of the principal national securities exchange, if any, on which the
Notes are listed or, if the Notes are not then listed on a national security exchange, on a pro rata basis or by lot (except that any Notes represented by a Global Note will be redeemed by such method the Depositary may require);
provided, however that no Notes of $1.00 in original principal amount or less shall be redeemed in part. 
 On and after the
redemption date, interest will cease to accrue on Notes or portions of them called for redemption so long as the Issuer has deposited with the Paying Agent funds in satisfaction of the applicable redemption price pursuant to this Indenture
(including accrued and unpaid interest on the Notes to be redeemed). The Trustee shall promptly notify the Issuer in writing of the Notes selected for redemption. The Trustee may select for redemption portions (equal to a minimum of $1.00 or any
integral multiples of $1.00 thereof) of the principal of the Notes that have denominations larger than $1.00. 

Section 3.3 Notice of Redemption. The Issuer shall deliver or cause to be delivered in accordance with
Section 11.2, a notice of redemption to each Holder whose Notes are to be redeemed (with a copy to the Trustee), at least 30 days but not more than 60 days before a redemption date (except that notices may be delivered more than 60 days before
a redemption date if the notice is issued in accordance with Article VIII). 
 The notice shall identify the Notes to be redeemed (including
“CUSIP” numbers and corresponding “ISINs”, if applicable) and shall state: 
 (1) the redemption date;

 (2) the redemption price (or the method by which it is to be determined); 

(3) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the
redemption date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note (or appropriate adjustments to the amount and beneficial interests in a
Global Note will be made, as appropriate); 
 (4) the name and address of the Paying Agent; 

(5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; 

  
 46 

 (6) that, unless the Issuer defaults in making such redemption payment,
interest, if any, on Notes called for redemption ceases to accrue on and after the redemption date; 
 (7) the paragraph of
the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; 
 (8) that
no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes; 

(9) if applicable, that the Issuer will commence an Optional Conversion Offer in accordance with Section 12.1(b) to allow
Holders to exercise their rights to an Optional Conversion; and 
 (10) if applicable, that such notice of redemption is
subject to the sole condition that less than 100% in aggregate principal of all outstanding Notes are tendered in the related Optional Conversion Offer. 

At the Issuer’s written request, the Trustee shall give the notice of redemption in the Issuer’s name and at the Issuer’s
expense; provided, however, that the Issuer shall have delivered to the Trustee, at least 15 days prior to the date of the giving of the notice of redemption (or such shorter period as is acceptable to the Trustee), an Officers’
Certificate requesting that the Trustee give such notice and setting forth the information to be stated in the notice as provided in the preceding paragraph. The notice sent in the manner herein provided shall be deemed to have been duly given
whether or not the Holder receives such notice. In any case, failure to give such notice or any defect in the notice to the Holder of any Note shall not affect the validity of the proceeding for the redemption of any other Note. 

Notices of redemption shall be irrevocable and may not be conditional; provided, however, that notices of redemption may be subject to the
sole condition that less than 100% in aggregate principal amount of all outstanding Notes are tendered in the related Optional Conversion Offer and, upon the settlement of any Optional Conversion Offer related to such notice of redemption, the
Issuer shall be entitled to amend such notice of redemption to reduce the aggregate principal amount of Notes to be redeemed in proportion to the amount of Notes tendered in such Optional Conversion Offer. 

Section 3.4 Effect of Notice of Redemption. Once notice of redemption is delivered in accordance with
Section 3.3, Notes called for redemption become due and payable on the redemption date at the applicable redemption price, subject to satisfaction of any conditions (as permitted by Section 3.3) specified in the notice of redemption and,
in the case of an Optional Conversion Offer, the rights of Holders described in Section 12.1. 
 Section 3.5
Deposit of Redemption Price. On or before 11:00 a.m. (New York City time) on the redemption date, the Issuer shall deposit with the Trustee or with the Paying Agent (other than the Issuer or an Affiliate of the Issuer) money
sufficient to pay the redemption price on all Notes to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Issuer any money deposited with the Trustee or the Paying Agent by the Issuer in excess of the amounts
necessary to pay the redemption price of all Notes to be redeemed. 

  
 47 

 If Notes called for redemption or tendered in a Net Proceeds Offer or Change of Control
Offer are paid or if the Issuer has deposited with the Trustee or Paying Agent money sufficient to pay the redemption or purchase price of, and unpaid and accrued interest on, all Notes to be redeemed or purchased, on and after the redemption or
purchase date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption or tendered and not withdrawn in a Net Proceeds Offer or Change of Control Offer (regardless of whether certificates for such securities are
actually surrendered). If a Note is redeemed or purchased on or after an interest record date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was
registered at the close of business on such record date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Issuer to comply with the preceding paragraph, interest shall be paid on the
unpaid principal from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case, at the rate provided in the Notes and in Section 4.1. 

Section 3.6 Notes Redeemed in Part. Upon surrender and cancellation of a Note that is redeemed in
part, the Issuer shall issue and, upon the written request of an Officer of the Issuer, the Trustee shall authenticate for the Holder at the expense of the Issuer a new Note equal in principal amount to the unredeemed portion of the Note surrendered
and canceled; provided that each such new Note will be in a minimum principal amount of $1.00 or integral multiples of $1.00 in excess thereof. 

Section 3.7 Optional Redemption. 

(a) Subject to the rights of Holders described in Section 12.1, the Notes may be redeemed, in whole or in part, at any
time or from time to time prior to August 4, 2022 at the option of the Issuer, at a redemption price equal to 100.0% of the principal amount of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest to, the
applicable redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date). The Issuer will calculate the Treasury Rate and Applicable Premium and, prior to the
redemption date, file an Officers’ Certificate with the Trustee setting forth the Treasury Rate and Applicable Premium and showing the calculation of each in reasonable detail. 

(b) At any time or from time to time on or after August 4, 2022, the Issuer, at its option, may redeem the Notes, in whole
or in part, at the redemption prices (expressed as percentages of principal amount of the Notes to be redeemed) set forth below, together with accrued and unpaid interest to, but not including, the applicable redemption date (subject to the right of
the Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date), if redeemed during the 12-month period beginning August 4 of the years indicated below:

  

					
	 Year
	  	Redemption Price	 
	 2022
	  	 	104.500	% 
	 2023
	  	 	102.500	% 
	 2024 and thereafter
	  	 	100.000	% 

  
 48 

 (c) Notwithstanding anything to the contrary herein, the Notes may not be
redeemed or called for redemption, in whole or in part, at any time prior to the time that the Required Stockholder Approval shall have been obtained. 

Article IV 
 COVENANTS

 Section 4.1 Payment of Notes. 

(a) The Issuer shall pay or cause to be paid the principal of, premium (including the Applicable Premium and Redemption
Premium), if any, and interest on the Notes on the dates and in the manner provided in the Notes and this Indenture; provided that if more than $16.5 million in aggregate principal amount of Old Notes remain outstanding as of
June 30, 2021, the Notes will mature on June 30, 2021. Principal, premium (including the Applicable Premium and the Redemption Premium), if any, and Cash Interest shall be considered paid for all purposes hereunder on the date the Trustee
or the Paying Agent (if other than the Issuer or a Subsidiary thereof) holds, as of 11:00 a.m. (New York City time) on the relevant payment date, U.S. dollars deposited by the Issuer in immediately available funds and designated for and sufficient
to pay all such principal, premium (including the Applicable Premium and Redemption Premium), if any, and interest then due. In the event that Issuer determines to pay PIK Interest for any interest period, then Issuer will deliver a notice (a
“PIK Notice”) to the Trustee prior to the record date for the next Interest Payment Date, which notice will state the total amount of interest to be paid on the Interest Payment Date in respect of such interest period and the amount of
such interest to be paid as PIK Interest. The Trustee, on behalf of and at the expense of the Issuer, will promptly deliver a corresponding notice provided by the Issuer to the Holders. For the avoidance of doubt, interest on the Notes in respect of
any interest period for which a PIK Notice is not delivered must be paid entirely in cash. PIK Interest will be considered paid on the date due if on such date the Trustee has received (i) a written order, pursuant to Section 2.2, from the
Issuer signed by an Officer of the Issuer to increase the balance of any Global Note to reflect such PIK Interest or (ii) PIK Interest Notes duly executed by the Issuer together with a written order, pursuant to Section 2.2, of the Issuer
signed by an Officer of the Issuer requesting the authentication of such PIK Interest Notes by the Trustee. In connection with the payment of PIK Interest in respect of the Notes, the Issuer will, without the consent of Holders (and without regard
to any restrictions or limitations set forth under Section 4.9), either increase the outstanding principal amount of the Notes or issue PIK Interest Notes under this Indenture. 

(b) Interest will be payable, at the election of the Issuer (made by delivering a notice to the Trustee prior to the record
date for the next Interest Payment Date), (1) entirely in cash (“Cash Interest”) or (2) by paying 6.250% per annum as Cash Interest and 2.750% per annum by increasing the principal amount of the outstanding Notes or

  
 49 

 
by issuing PIK Interest Notes having a principal amount equal to the amount of interest so paid (“PIK Interest”). Interest on the Notes will accrue from the date of original
issuance or, if interest has already been paid, from and including the most recent date to which interest has been paid. Interest on the Notes will be computed on the basis of a 360-day year of twelve 30-day months. 
 Notwithstanding anything to the contrary, the payment of accrued interest
at maturity or in connection with any redemption or purchase of Notes, as described under Sections 3.7, 4.10 and 4.13 will be made solely in cash. 

(c) The Issuer shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue
principal at the rate equal to the then applicable interest rate on the Notes to the extent lawful; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without
regard to any applicable grace period) at the same rate to the extent lawful. 
 Section 4.2 Maintenance of
Office or Agency. The Issuer shall maintain an office or agency where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Issuer and Guarantors in respect of the Notes and this
Indenture may be served. The Issuer shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Issuer shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. 

The Issuer may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations. The Issuer shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 

The Issuer hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Issuer in accordance with
Section 2.3. 
 Section 4.3 Provision of Financial Information(a) . (a) Whether or not required
by the SEC, so long as any Notes are outstanding, the Issuer will furnish to the Trustee and the Holders of Notes, or, to the extent permitted by the SEC, file electronically with the SEC through the SEC’s Electronic Data Gathering, Analysis
and Retrieval System (or any successor system) within the time periods specified in the SEC’s rules and regulations: 

(1) all quarterly and annual reports that would be required to be filed with the SEC on Forms
10-Q and 10-K if the Issuer were required to file such reports; and 

(2) all current reports that would be required to be filed with the SEC on Form 8-K if
the Issuer were required to file such reports. 

  
 50 

 For so long as any Notes remain outstanding, the Issuer will furnish to the
Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. 

Delivery of such reports to the Trustee is for informational purposes only, and the Trustee’s receipt thereof shall not
constitute actual or constructive knowledge or notice of any information contained therein or determinable from information contained therein, including the Issuer’s, any Guarantor’s or any other person’s compliance with any of the
covenants under this Indenture or the Notes (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). The Trustee will not be obligated to monitor or confirm, on a continuing basis or otherwise, the Issuer’s, any
Guarantor’s or any other person’s compliance with this covenant or to determine whether such reports have been posted on any website or filed with the SEC through EDGAR (or any successor system). 

(b) The Issuer, or one of its representatives, agents or employees, shall calculate and deliver to the Trustee in writing all
OID information to be reported to the Trustee to Holders as required by applicable law. 
 Section 4.4
Compliance Certificate. The Issuer shall deliver to the Trustee and Notes Collateral Agent, within 90 days after the end of each fiscal year beginning with the fiscal year ending December 31, 2020, an Officers’
Certificate stating that a review of the activities of the Issuer and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether each has kept, observed, performed
and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that, to his or her knowledge, each entity has kept, observed, performed and fulfilled each and every covenant contained in
this Indenture and is not in default 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 Issuer is taking or proposes to take with respect thereto) and that, to his or her knowledge, no event has occurred and remains in existence by reason of which payments on account of the
principal of, premium (including the Applicable Premium and Redemption Premium), if any, or interest on the Notes is prohibited or if such event has occurred, a description of the event and what action the Issuer is taking or proposes to take with
respect thereto. 
 The Issuer shall, so long as any of the Notes are outstanding, deliver to the Trustee, within 30 days after any Officer
becomes aware of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Issuer is taking or proposes to take with respect thereto. 

Section 4.5 Taxes. The Issuer shall pay, and shall cause each of its Subsidiaries to pay, prior to
delinquency all material taxes, assessments and governmental levies, except such as are contested in good faith and by appropriate proceedings and with respect to which appropriate reserves have been taken in accordance with GAAP or where the
failure to effect such payment is not adverse in any material respect to the Holders of the Notes. 

  
 51 

 Section 4.6 Stay, Extension and Usury Laws. The
Issuer and each of the Guarantors 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 wherever
enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture, and the Issuer and each of the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage
of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has
been enacted. 
 Section 4.7 Limitation on Restricted Payments. 

(a) The Issuer shall not, and shall not permit any Subsidiary to, directly or indirectly, make any Restricted Payment, except:

 (1) the payment of any dividend or redemption payment or the making of any distribution within 60 days after the date of
declaration thereof if, on the date of declaration, the dividend, redemption or distribution payment, as the case may be, would have complied with the provisions of this Indenture; 

(2) any Restricted Payment made in exchange for, or out of the proceeds of, the substantially concurrent issuance and sale of
Qualified Equity Interests; 
 (3) the purchase, repurchase, redemption, defeasance or other acquisition or retirement for
value of Subordinated Indebtedness of the Issuer or any Subsidiary in exchange for, or out of the proceeds of, the substantially concurrent incurrence of, Refinancing Indebtedness permitted to be incurred under Section 4.9 and the other terms

Section 4.13 or (B) at a purchase price not greater than 100.0% of the principal amount thereof in accordance with provisions similar to Section 4.10; provided that, prior to or simultaneously with such purchase, repurchase,

been applied to the payment of Restricted Payments pursuant to this clause (5), plus (iii) the net cash proceeds of any “key-man” life insurance policies that have not been applied to the
payment of Restricted Payments pursuant to this clause (5); and provided further that cancellation of Indebtedness owing to the Issuer from members of management of the Issuer or any Subsidiary in connection with a repurchase of Equity
Interests of the Issuer will not be deemed to constitute a Restricted Payment for purposes of this Section 4.7 or any other provision of this Indenture;

Issuer and its Subsidiaries immediately following such Restricted Payment is no greater than 3.00 to 1.00; or 
 (13)
Restricted Payments made pursuant to the immediately succeeding paragraph. 
 (b) The Issuer will not, and will not permit
any Subsidiary to, directly or indirectly, after the Issue Date, make any principal payment on, purchase, redemption, defeasance, prepayment or other acquisition or retirement for value, or any other payment in respect of the then-outstanding
principal amount (or any default judgement in respect of such principal amount) of the Old Notes (including, without limitation, any payment of principal at maturity, or upon any mandatory prepayment, of the Old Notes but excluding any regularly
scheduled interest payments), except for any such payments made:

(3); 
 provided, that in the event of any payment made pursuant to clauses (1) through (4) above, such payment shall be made for a
purchase price not to exceed par plus accrued and unpaid interest. 
 For the purposes of determining compliance with any U.S.
dollar-denominated restriction on Restricted Payments denominated in a foreign currency, the U.S. dollar-equivalent amount of such Restricted Payment shall be calculated based on the relevant currency exchange rate in effect on the date that such
Restricted Payment was made. The amount of any Restricted Payment (other than cash) will be the Fair Market Value on the date of the Restricted Payment (or, in the case of a dividend, on the date of declaration) of the assets or securities proposed
to be transferred or issued by the Issuer or such Subsidiary, as the case may be, pursuant to the Restricted Payment.

 Section 4.8 Limitation on Dividend and Other Restrictions
Affecting Subsidiaries. The Issuer shall not, and shall not permit any Subsidiary to, directly or indirectly, create or otherwise cause or permit to exist or become effective any consensual encumbrance or consensual restriction
on the ability of any Subsidiary to: 
 (a) pay dividends or make any other distributions on or in respect of its Equity
Interests to the Issuer or any of its Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits (it being understood that the priority of any Preferred Stock in receiving dividends or liquidating
distributions prior to dividends or liquidating distributions being paid on Capital Stock shall not be deemed a restriction on the ability to make distributions on Equity Interests); 

(b) make loans or advances, or pay any Indebtedness or other obligation owed, to the Issuer or any other Subsidiary (it being
understood that the subordination of loans or advances made to the Issuer or any Subsidiary to other Indebtedness or obligations incurred by the Issuer or any Subsidiary shall not be deemed a restriction on the ability to make loans or advances); or

 (c) transfer any of its property or assets to the Issuer or any other Subsidiary (it being understood that such transfers
shall not include any type of transfer described in clause (a) or (b) above); except for, in each case:

(4) any agreement or other instrument of a Person acquired by the Issuer or any of its Subsidiaries in existence at the time of
such acquisition (but not created in contemplation thereof), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person and its Subsidiaries, or the property or assets of the
Person and its Subsidiaries, so acquired (including after acquired property); 
 (5) any amendment, restatement,
modification, renewal, increases, supplement, refunding, replacement or refinancing of an agreement referred to in clauses (1), (2), (3), (4), (10) or this clause (5); provided, however, that such amendments, restatements, modifications,
renewals, increases, supplements, refunding, replacements or refinancing are, in the good faith judgment of the Issuer, not materially more restrictive, taken as a whole, than the encumbrances and restrictions contained in the agreements referred to
in such clauses on the Issue Date or the date such Subsidiary became a Subsidiary or was merged into a Subsidiary, whichever is applicable; 

  
 55 

 (6) encumbrances or restrictions existing under or by reason of applicable
law, regulation or order;

(9) restrictions imposed under any agreement to sell Equity Interests or assets, as permitted under this Indenture, to any
Person pending the closing of such sale; 
 (10) any other agreement governing Indebtedness or other obligations entered into
after the Issue Date that either (A) contains encumbrances and restrictions that in the good faith judgment of the Issuer are not materially more restrictive, taken as a whole, with respect to any Subsidiary than those in effect on the Issue
Date with respect to that Subsidiary pursuant to agreements in effect on the Issue Date or those contained in this Indenture, the Notes, the Security Documents and the Note Guarantees or (B) any such encumbrance or restriction contained in
agreements or instruments governing such Indebtedness that is customary and does not prohibit (except upon a default or an event of default thereunder) the payment of dividends in an amount sufficient, as determined by the Issuer in good faith, to
make scheduled payments of cash interest and principal on the Notes when due; 
 (11) customary provisions in partnership
agreements, limited liability company organizational governance documents, joint venture agreements, shareholder agreements and other similar agreements entered into in the ordinary course of business that restrict the disposition or distribution of
ownership interests in or assets of such partnership, limited liability company, joint venture, corporation or similar Person;

(14) [reserved]; 

  
 56 

 (15) with respect to any Foreign Subsidiary, any encumbrance or restriction
contained in the terms of any Indebtedness or any agreement pursuant to which such Indebtedness was incurred if either (A) the encumbrance or restriction applies only in the event of a payment default or a default with respect to a financial
covenant in such Indebtedness or agreement or (B) the Issuer determines that any such encumbrance or restriction will not materially affect the Issuer’s ability to make principal or interest payments on the Notes, as determined in good
faith by the Board of Directors of the Issuer, whose determination shall be conclusive; and 
 (16) supermajority voting
requirements existing under corporate charters, by-laws, stockholders agreements and similar documents and agreements. 

Section 4.9 Limitation on Additional Indebtedness. 

(a) The Issuer shall not, and shall not permit any Subsidiary to, directly or indirectly, incur any Indebtedness (including
Acquired Indebtedness); provided that the Issuer or any Guarantor may incur additional Indebtedness (including Acquired Indebtedness), in each case, if, after giving effect thereto on a pro forma basis (including giving pro forma effect to
the application of the proceeds thereof), the Issuer’s Fixed Charge Coverage Ratio would be at least 2.00 to 1.00 (the “Coverage Ratio Exception”). 

(b) Notwithstanding the above, each of the following incurrences of Indebtedness shall be permitted (the “Permitted
Indebtedness”): 
 (1) Indebtedness of the Issuer or any Subsidiary under one or more Credit Facilities in an
aggregate principal amount at any time outstanding, including the issuance and creation of letters of credit and bankers’ acceptances thereunder (with letters of credit and bankers’ acceptances being deemed to have a principal amount equal
to the face amount thereof), not to exceed (A) in the case of the Issuer, any Guarantor or any non-Guarantor Canadian Subsidiary, $300.0 million (no more than $30.0 million of which may be
incurred by non-Guarantor Canadian Subsidiaries); and (B) in the case of any other non-Guarantor Subsidiary, $20.0 million; 

(2) (A) the Notes issued on the Issue Date, (B) Additional Notes issued after the Issue Date in an aggregate principal

are issued solely to refinance such Old Notes after the Issue Date in accordance with Section 4.7(b), (C) any PIK Interest Notes issued from time to time to pay PIK Interest in accordance with the terms of this Indenture and any increase in the
principal amount of Notes from time to time to pay PIK Interest in accordance with the terms of this Indenture, and (D) the Note Guarantees with respect to the foregoing; 

  
 57 

 (3) Indebtedness of the Issuer and its Subsidiaries to the extent
outstanding on the Issue Date after giving effect to the Exchange Offer and the cancellation of the Old Notes purchased thereunder (other than Indebtedness referred to in clauses (1), (2), (6) and (16) of this Section 4.9(b)); 

(4) (A) the guarantee by the Issuer or any Guarantor of Indebtedness of the Issuer or any Guarantor that was permitted to be
incurred by another provision of this Section 4.9, (B) the guarantee by any non-Guarantor Subsidiary of Indebtedness of the Issuer or any Subsidiary that was permitted to be incurred by another provision
of this Section 4.9, or (C) any guarantee by the Issuer or any Guarantor of Indebtedness of any non-Guarantor Subsidiary incurred pursuant to Section 4.9(b)(1)(B); 

(5) Indebtedness under Hedging Obligations entered into for bona fide hedging purposes of the Issuer or any Subsidiary in the
ordinary course of business and not for the purpose of speculation; provided that in the case of Hedging Obligations relating to interest rates, (A) such Hedging Obligations relate to payment obligations on Indebtedness otherwise
permitted to be incurred by this Section 4.9, and (B) the notional principal amount of such Hedging Obligations at the time incurred does not exceed the principal amount of the Indebtedness to which such Hedging Obligations relate; 

(6) Indebtedness of the Issuer owed to and held by a Subsidiary and Indebtedness of any Subsidiary owed to and held by the
Issuer or any other Subsidiary; provided, however, that 
 (A) if the Issuer is the obligor on Indebtedness and a
Subsidiary that is not a Guarantor is the obligee, such Indebtedness is expressly subordinated to the prior payment in full in cash of all obligations with respect to the Notes; 

(B) if a Guarantor is the obligor on such Indebtedness and a Subsidiary that is not a Guarantor is the obligee, such
Indebtedness is subordinated in right of payment to the Note Guarantee of such Guarantor; and 
 (C) 

(i) any subsequent issuance or transfer of Equity Interests or any other event which results in any such Indebtedness being
held by a Person other than the Issuer or any other Subsidiary; and 
 (ii) any sale or other transfer of any such
Indebtedness to a Person other than the Issuer or any other Subsidiary shall be deemed, in each case of this clause (C), to constitute an incurrence of such Indebtedness not permitted by this clause (6); 

  
 58 

 (7) Indebtedness in respect of workers’ compensation claims, bank
guarantees, warehouse receipt or similar facilities, property, casualty or liability insurance, take-or-pay obligations in supply arrangements, self-insurance

greater than 3.00 to 1.00, $25.0 million; 
 (9) Indebtedness arising from the honoring by a bank or other financial
institution of a check, draft or similar instrument inadvertently (except in the case of daylight overdrafts) drawn against insufficient funds in the ordinary course of business;

unsecured indemnification, adjustment of purchase price, earn-out or similar obligations, in each case, incurred or assumed in connection with the acquisition or disposition of any business or assets of the
Issuer or any Subsidiary or Equity Interests of a Subsidiary, other than guarantees of Indebtedness incurred by any Person acquiring all or any portion of such business, assets or Equity Interests for the purpose of financing or in contemplation of
any such acquisition; provided that (A) any amount of such obligations included on the face of the balance sheet of the Issuer or any Subsidiary shall not be permitted under this clause (12) (contingent obligations referred to on the
face of a balance sheet or in a footnote thereto and not otherwise quantified and reflected on the balance sheet will not be deemed “included on the face of the balance sheet” for purposes of the foregoing) and (B) in the case of a
disposition, the maximum aggregate liability in respect of all such obligations outstanding under this clause (12) shall at no time exceed the gross proceeds actually received by the Issuer and the Subsidiaries in connection with such
disposition; 

  
 59 

 (13) additional Indebtedness of the Issuer or any Subsidiary that is a
Guarantor in an aggregate principal amount which, when taken together with the principal amount of all other Indebtedness incurred pursuant to this clause (13) and then outstanding, will not exceed $25.0 million; 

(14) Indebtedness in respect of Specified Cash Management Agreements entered into in the ordinary course of business; 

(15) Indebtedness of Persons incurred and outstanding on the date on which such Person was acquired by the Issuer or any
Subsidiary, or merged or consolidated with or into the Issuer or any Subsidiary (other than Indebtedness incurred in connection with, or in contemplation of, such acquisition, merger or consolidation); provided, that at the time such Person
or assets is/are acquired by the Issuer or a Subsidiary, or merged or consolidated with the Issuer or any Subsidiary and after giving pro forma effect to the incurrence of such Indebtedness pursuant to this clause (15) and any other related
Indebtedness, either (A) the Issuer would have been able to incur $1.00 of additional Indebtedness pursuant to the Coverage Ratio Exception; or (B) the Fixed Charge Coverage Ratio of the Issuer and its Subsidiaries would be greater than or
equal to such Fixed Charge Coverage Ratio immediately prior to such acquisition, merger or consolidation; and 
 (16) (A) Old
Notes in an aggregate principal amount not to exceed the aggregate principal amount of Old Notes outstanding on the Issue Date after giving effect to the Exchange Offer and the cancellation of the Old Notes purchased thereunder; provided, that no
additional Old Notes shall be issued or incurred following the Issue Date; (B) Permitted Old Notes Refinancing Indebtedness and (C) any Indebtedness incurred to redeem, refinance, replace, defease, discharge, refund or otherwise retire for
value Permitted Old Notes Refinancing Indebtedness, provided that any Indebtedness incurred pursuant to this clause (C) must conform to the definition of Permitted Old Notes Refinancing Indebtedness, with each reference to Old Notes contained
therein deemed to be a reference to any then outstanding Permitted Old Notes Refinancing Indebtedness. 
 The Issuer will not incur, and
will not permit any Guarantor to incur, any Indebtedness (including Permitted Indebtedness) (x) that is contractually subordinated in right of payment to any other Indebtedness of the Issuer or such Guarantor unless such Indebtedness is also
contractually subordinated in right of payment to the Notes and the applicable Note Guarantee on substantially identical terms; or (y) that is secured by a Lien on the Collateral on a subordinated or junior basis to any other Indebtedness and
on a senior basis to the Notes or the Note Guarantee of such Guarantor (including, without limitation, any Indebtedness subject to a so called “one and a half lien” or similar lien structure). 

  
 60 

 For purposes of determining compliance with this Section 4.9, in the event that an item
of Indebtedness meets the criteria of more than one of the categories of Permitted Indebtedness described in clauses (1) through (16) above or is entitled to be incurred pursuant to the Coverage Ratio Exception, the Issuer shall, in its sole
discretion, classify such item of Indebtedness and may divide and classify such Indebtedness in more than one of the types of Indebtedness described (except that all Indebtedness outstanding under the Credit Agreement at any and all times shall be
deemed to have been incurred under clause (1) above and may not be reclassified) and may later reclassify any item of Indebtedness described in clauses (1) through (16) above (provided that at the time of reclassification it meets
the criteria in such category or categories). In addition, for purposes of determining any particular amount of Indebtedness under this Section 4.9, (i) guarantees, Liens or letter of credit obligations supporting Indebtedness otherwise
included in the determination of such particular amount shall not be included so long as incurred by a Person that could have incurred such Indebtedness; and (ii) the amount of Indebtedness issued at a price that is less than the principal
amount thereof will be equal to the amount of the liability in respect thereof determined in accordance with GAAP. 
 The accrual of
interest, the accretion or amortization of original issue discount and the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms will not be deemed to be an incurrence of Indebtedness of this covenant;
provided, in each such case, that the amount thereof is included in Consolidated Interest Expense of the Issuer as accrued. 
 For the
purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness denominated in a foreign currency, the U.S. dollar-equivalent principal amount of such Indebtedness incurred pursuant thereto shall be
calculated based on the relevant currency exchange rate in effect on the earlier of the date that such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided
that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency
exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such Refinancing Indebtedness does not exceed the principal amount of such
Indebtedness being refinanced. The principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate
applicable to the currencies in which such Refinancing Indebtedness is denominated that is in effect on the date of such refinancing. 

Section 4.10 Limitation on Asset Sales. 

(a) The Issuer shall not, and shall not permit any Subsidiary to, directly or indirectly, consummate any Asset Sale unless:

 (1) the Issuer or such Subsidiary, as the case may be, receives consideration at least equal to the Fair Market Value
(such Fair Market Value to be determined on the date of contractually agreeing to such Asset Sale) of the Equity Interests or assets subject to such Asset Sale; and 

  
 61 

 (2) (A) at least 75.0% of the total consideration from such Asset Sale is in
the form of cash or Cash Equivalents or (B) the Fair Market Value of all forms of consideration other than cash or Cash Equivalents received for all Asset Sales since the Issue Date does not exceed in the aggregate $5.0 million. 

For purposes of clause (2) above and for no other purpose, the following shall be deemed to be cash: 

(A) the amount (without duplication) of any liabilities (as shown on the Issuer’s or such Subsidiary’s most recent
balance sheet) (other than Subordinated Indebtedness (excluding any Indebtedness that is deemed Subordinated Indebtedness pursuant to clauses (2) or (3) of the definition thereof to the extent that such Indebtedness may be repaid pursuant to
clause (3) of Section 4.10(b) from the Net Available Proceeds of such Asset Sale) or intercompany Indebtedness) of the Issuer or such Subsidiary that is expressly assumed by the transferee of any such assets pursuant to a written agreement
that releases the Issuer or such Subsidiary from further liability therefor; 
 (B) the amount of any securities, notes or
other obligations received from such transferee that are within 180 days after such Asset Sale converted by the Issuer or such Subsidiary into cash (to the extent of the cash actually so received); 

(C) any assets or Equity Interests of the kind referred to in clause (4) of Section 4.10(b); and 

(D) accounts receivable of a business retained by the Issuer or any Subsidiary, as the case may be, following the sale of such
business, provided that such accounts receivable (i) are not past due more than 60 days and (ii) do not have a payment date greater than 90 days from the date of the invoices creating such accounts receivable. 

In the case of any Asset Sale pursuant to a condemnation, seizure, appropriation or similar taking, including by deed in lieu of condemnation,
or any actual or constructive total loss or an agreed or compromised total loss, such Asset Sale shall not be required to satisfy the requirements of clauses (1) and (2) of this Section 4.10(a). 

If at any time any non-cash consideration received by the Issuer or any Subsidiary, as the case may
be, in connection with any Asset Sale is repaid or converted into or sold or otherwise disposed of for cash (other than interest received with respect to any such non-cash consideration), then the date of such
repayment, conversion or disposition shall be deemed to constitute the date of an Asset Sale hereunder and the Net Available Proceeds thereof shall be applied in accordance with this Section 4.10. 

  
 62 

 (b) If the Issuer or any Subsidiary engages in an Asset Sale, the Issuer or
such Subsidiary may, no later than 365 days following the consummation thereof, apply all or any of the Net Available Proceeds therefrom to: 

(1) to the extent such Net Available Proceeds constitute proceeds from the sale of ABL Priority Collateral, to repay
Indebtedness under the Credit Agreement secured by such ABL Priority Collateral or the Notes; 
 (2) to the extent such Net
Available Proceeds constitute proceeds from the sale of Collateral, to repay the Notes; 
 (3) to the extent such Net
Available Proceeds do not constitute proceeds from the sale of Collateral, (A) to repay, repurchase, redeem, defease or otherwise retire any Indebtedness secured by a Lien on the assets or Equity Interests subject to such Asset Sale, or
(B) to repay the Notes; or 
 (4) (A) make any capital expenditure or otherwise invest all or any part of the Net
Available Proceeds thereof in the purchase of assets (other than securities and excluding working capital or current assets for the avoidance of doubt) to be used by the Issuer or any Subsidiary in a Permitted Business, (B) acquire Qualified
Equity Interests held by a Person other than the Issuer or any of its Subsidiaries in a Person that is a Subsidiary or in a Person engaged in a Permitted Business that shall become a Subsidiary immediately upon the consummation of such acquisition,
so long as, immediately after giving effect to the application of such Net Available Proceeds pursuant to this clause (4)(B) on a pro forma basis, either (i) the Issuer would have been able to incur $1.00 of additional Indebtedness pursuant to
the Coverage Ratio Exception; or (ii) the Fixed Charge Coverage Ratio of the Issuer and its Subsidiaries would be greater than or equal to such Fixed Charge Coverage Ratio immediately prior to such acquisition; or (C) a combination of
(A) and (B) (subject to the limitation set forth in such clause (B)); provided that the requirements of this clause (4) will be deemed to be satisfied with respect to any Asset Sale if the Issuer or any Subsidiary enters into an agreement
committing to make the acquisition, investment or expenditure referred to above within 365 days after the receipt of such Net Available Proceeds with the good faith expectation that such Net Available Proceeds will be applied to satisfy such
commitment in accordance with such agreement within 180 days after such 365-day period, and if such Net Available Proceeds are not so applied within such 180-day period,
then such Net Available Proceeds will constitute Excess Proceeds (as defined below). 
 The amount of Net Available Proceeds not applied or
invested as provided in clauses (1) through (4) of this Section 4.10(b) shall constitute “Excess Proceeds.” 

(c) On the 366th day after an Asset Sale (or, at the Issuer’s option, an earlier date), if the aggregate amount of Excess
Proceeds equals or exceeds $25.0 million, the Issuer shall be required to make an offer to purchase or redeem (a “Net Proceeds Offer”) from all Holders the maximum principal amount of Notes to which the Net Proceeds Offer
applies that may be purchased or redeemed out of the Excess Proceeds, at an offer price in cash in an amount equal to 100.0% of the principal amount of the Notes plus accrued and unpaid interest thereon, if any, to the date of purchase, in
accordance with the procedures set forth in this Indenture in minimum denominations of $1.00 or integral multiples of $1.00 in excess thereof. 

  
 63 

 To the extent that the aggregate principal amount of Notes so validly tendered pursuant to a
Net Proceeds Offer is less than the Excess Proceeds, the Issuer may use any remaining Excess Proceeds, or a portion thereof, for any purposes not otherwise prohibited by the provisions of this Indenture. If the aggregate principal amount of Notes so
validly tendered pursuant to a Net Proceeds Offer exceeds the amount of Excess Proceeds, the Issuer shall select the Notes to be purchased on a pro rata basis on the basis of the aggregate outstanding principal amount of Notes. Upon
completion of such Net Proceeds Offer in accordance with the foregoing provisions, the amount of Excess Proceeds with respect to which such Net Proceeds Offer was made shall be deemed to be zero. 

(d) The Net Proceeds Offer will remain open for a period of 20 Business Days following its commencement, except to the extent
that a longer period is required by applicable law (the “Net Proceeds Offer Period”). No later than five (5) Business Days after the termination of the Net Proceeds Offer Period (the “Net Proceeds Purchase
Date”), the Issuer will purchase the principal amount of Notes required to be purchased pursuant to this Section 4.10 (the “Net Proceeds Offer Amount”) or, if less than the Net Proceeds Offer Amount has been so validly
tendered, all Notes validly tendered in response to the Net Proceeds Offer. 
 If the Net Proceeds Purchase Date is on or after an interest
record date and on or before the related Interest Payment Date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to
Holders who tender Notes pursuant to the Net Proceeds Offer. 
 Pending the final application of any Net Available Proceeds pursuant to this
Section 4.10, the holder of such Net Available Proceeds may apply such Net Available Proceeds temporarily to reduce Indebtedness outstanding under a revolving Credit Facility or otherwise invest such Net Available Proceeds in any manner not
prohibited by this Indenture. 
 On or before the Net Proceeds Purchase Date, the Issuer will, to the extent lawful, accept for payment, on
a pro rata basis to the extent necessary, the Net Proceeds Offer Amount of Notes or portions of Notes so validly tendered and not properly withdrawn pursuant to the Net Proceeds Offer, or if less than the Net Proceeds Offer Amount has been
validly tendered and not properly withdrawn, all Notes so validly tendered and not properly withdrawn, in each case in minimum denominations of $1.00 and integral multiples of $1.00 in excess thereof. The Issuer or the Paying Agent, as the case may
be, will promptly (but in any case not later than five (5) Business Days after termination of the Net Proceeds Offer Period) mail or deliver to each tendering Holder and the Issuer will mail or deliver to each tendering Holder an amount equal
to the purchase price of the Notes so validly tendered and not properly withdrawn by such Holder and accepted by the Issuer for purchase, and the Issuer will promptly issue a new Note, and the Trustee, upon delivery of an Officers’ Certificate
from the Issuer, will authenticate and mail or deliver such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered; provided that each such new Note will be in a minimum principal amount of
$1.00 or an integral multiple of $1.00 in excess thereof. Any Note not so accepted will be promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer will publicly announce the results of the Net Proceeds Offer as soon as
practicable after the Net Proceeds Purchase Date. 

  
 64 

 Notwithstanding the foregoing, the sale, conveyance or other disposition of all or
substantially all of the assets of the Issuer and its Subsidiaries, taken as a whole, will be governed by Section 4.13 and/or Section 5.1 and not by this Section 4.10. 

In connection with the purchase of Notes pursuant to a Net Proceeds Offer, the Issuer shall (i) comply with all applicable securities
legislation in the United States, including, without limitation, the tender offer rules under the Exchange Act that may then be applicable and (ii) file a Schedule TO or any other required schedules under the Exchange Act; in each case, so as
to permit the rights and obligations under this section to be exercised in the time and in the manner specified in this section. To the extent that the provisions of any applicable securities laws or regulations conflict with this Section 4.10,
the Issuer shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.10 by virtue of such compliance. 

Section 4.11 Limitation on Transactions with Affiliates. 

(a) The Issuer shall not, and shall not permit any of its Subsidiaries to, directly or indirectly, in one transaction or a
series of related transactions, sell, lease, transfer or otherwise dispose of any of its assets to, or purchase any assets from, or enter into any contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any
Affiliate (an “Affiliate Transaction”), unless: 
 (1) the terms of such Affiliate Transaction are not
materially less favorable to the Issuer or such Subsidiary, as the case may be, than those that could reasonably be expected to have been obtained in a comparable transaction at the time of such transaction in arm’s length dealings with a
Person who is not such an Affiliate, or if in the good faith judgment of the Issuer’s Board of Directors no comparable transaction is available with which to compare such Affiliate Transaction or are otherwise fair to the Issuer or such
Subsidiary from a financial point of view; 
 (2) the Issuer delivers to the Trustee, with respect to any Affiliate
Transaction involving aggregate value in excess of $10.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (1) above and which sets forth and authenticates a resolution that has been
adopted by the Independent Directors approving such Affiliate Transaction; and 
 (3) the Issuer delivers to the Trustee, in
addition to the requirements of clause (2) above, with respect to any Affiliate Transaction involving aggregate value in excess of $30.0 million, an opinion as to the fairness to the Issuer or such Subsidiary of such Affiliate Transaction;

  
 65 

 (b) The foregoing restrictions shall not apply to: 

(1) transactions to the extent between or among (A) the Issuer and one or more Subsidiaries or (B) Subsidiaries; 

(2) reasonable director, trustee, officer and employee compensation (including bonuses) and other benefits (including pursuant
to any employment agreement or any retirement, health, stock option or other benefit plan), payments or loans (or cancellation of loans) to employees of the Issuer and indemnification arrangements, in each case, as determined in good faith by the
Issuer’s Board of Directors or senior management; 
 (3) Permitted Investments (other than those made under clause
(1) of such definition) or Restricted Payments which are made in accordance with Section 4.7; 
 (4) any agreement
in effect on the Issue Date or as thereafter amended or replaced in any manner that, taken as a whole, is not materially less advantageous to the Issuer than such agreement as it was in effect on the Issue Date; 

(5) any transaction with a Person which would constitute an Affiliate of the Issuer solely because the Issuer or a Subsidiary
owns an Equity Interest in or otherwise controls such Person; 
 (6) transactions with customers, clients, suppliers, or
purchasers or sellers of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture; provided that in the reasonable determination of the Board of Directors of the Issuer or
the senior management of the Issuer, such transactions are on terms not materially less favorable to the Issuer or the relevant Subsidiary than those that could reasonably be expected to be obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate of the Issuer; 
 (7) the
issuance or sale of any Qualified Equity Interests of the Issuer and the granting of registration and other customary rights in connection therewith to, or the receipt of capital contributions from, Affiliates of the Issuer; 

(8) any transaction where the only consideration paid by the Issuer or the relevant Subsidiary is Qualified Equity Interests of
the Issuer; 
 (9) transactions between the Issuer or any Subsidiary and any Person, a director of which is also a director
of the Issuer or any direct or indirect parent company of the Issuer, and such director is the sole cause for such Person to be deemed an Affiliate of the Issuer or any Subsidiary; provided, however, that such director shall abstain
from voting as a director of the Issuer or such direct or indirect parent company, as the case may be, on any matter involving such other Person; and 

  
 66 

 (10) the entering into of a tax sharing agreement, or payments pursuant
thereto, between the Issuer and/or one or more Subsidiaries, on the one hand, and any other Person with which the Issuer or such Subsidiaries are required or permitted to file a consolidated tax return or with which the Issuer or such Subsidiaries
are part of a consolidated group for tax purposes to be used by such Person to pay taxes, and which payments by the Issuer and the Subsidiaries are not in excess of the tax liabilities that would have been payable by them on a stand-alone basis.

 Section 4.12 Limitation on Liens. The Issuer shall not, and shall not permit any Subsidiary to,
directly or indirectly, create, incur, assume or permit or suffer to exist any Lien (other than Permitted Liens) upon any of their property or assets (including Equity Interests of any Subsidiary), whether owned at the Issue Date or thereafter
acquired, which Lien secures Indebtedness. In addition, if the Issuer or any Guarantor, directly or indirectly, shall create, incur or suffer to exist any Lien securing obligations under the Credit Agreement or any other first-priority Lien on ABL
Priority Collateral (other than any cash collateral pledged to secure any letter of credit obligations thereunder), the Issuer or such Guarantor, as the case may be, must concurrently grant at least a second-priority Lien, subject to Permitted
Liens, upon such property as security for the Notes and the Note Guarantees. 
 Section 4.13 Offer to
Purchase upon Change of Control. Upon the occurrence of any Change of Control, unless the Issuer has previously or concurrently exercised its right to redeem all of the Notes as described under Section 3.7, each Holder will have the
right, except as provided below, to require that the Issuer purchase all or any portion (equal to a minimum of $1.00 or an integral multiple of $1.00 in excess thereof) of that Holder’s Notes for a cash price (the “Change of Control
Purchase Price”) equal to 101.0% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest thereon to the date of purchase. 

Not later than 30 days following any Change of Control, the Issuer will deliver, or cause to be delivered, to the Holders, with a copy to the
Trustee, a notice: 
 (1) describing the transaction or transactions that constitute the Change of Control; 

(2) offering to purchase, pursuant to the procedures required by this Indenture and described in the notice (a “Change
of Control Offer”), on a date specified in the notice, which shall be a Business Day not earlier than 30 days, nor later than 60 days, from the date the notice is delivered (the “Change of Control Payment Date”), and for
the Change of Control Purchase Price, all Notes properly tendered by such Holder pursuant to such Change of Control Offer prior to 5:00 p.m. New York time on the second Business Day preceding the Change of Control Payment Date; and 

(3) describing the procedures, as determined by the Issuer, consistent with this Indenture, that Holders must follow to accept
the Change of Control Offer. 

  
 67 

 On or before the Change of Control Payment Date, the Issuer will, to the extent lawful,
deposit with the Paying Agent an amount equal to the Change of Control Purchase Price in respect of the Notes or portions of Notes properly tendered. 

On the Change of Control Payment Date, the Issuer will, to the extent lawful: 

(1) accept for payment all Notes or portions of Notes (of a minimum of $1.00 or integral multiples of $1.00 in excess thereof)
properly tendered pursuant to the Change of Control Offer; and 
 (2) deliver or cause to be delivered to the Trustee the
Notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Issuer. 

The Paying Agent will promptly deliver to each Holder who has so tendered Notes the Change of Control Purchase Price for such Notes, and the
Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes so tendered, if any; provided that each such new Note will be in a
minimum principal amount of $1.00 or integral multiples of $1.00 in excess thereof. 
 If the Change of Control Payment Date is on or after
an interest record date and on or before the related Interest Payment Date, any accrued and unpaid interest, if any, will be paid on the relevant Interest Payment Date to the Person in whose name a Note is registered at the close of business on such
record date. 
 A Change of Control Offer shall remain open for at least 20 Business Days or for such longer period as is required by law.
The Issuer shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. 

The Issuer will not be required to make a Change of Control Offer upon a Change of Control if (i) a third party makes the Change of
Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Issuer and purchases all Notes properly tendered and not withdrawn under such
Change of Control Offer or (ii) in connection with or in contemplation of any publicly announced Change of Control, the Issuer has made an offer to purchase (an “Alternate Offer”) any and all Notes validly tendered at a cash
price equal to or higher than the Change of Control Purchase Price and has purchased all Notes properly tendered in accordance with the terms of the Alternate Offer. 

If Holders of not less than 90.0% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a
Change of Control Offer or Alternate Offer and the Issuer, or any third party making a Change of Control Offer in lieu of the Issuer as described above, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Issuer will
have the right, upon not less than 30 days’ nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer or Alternate Offer, as applicable, to redeem all Notes that remain
outstanding following such purchase at a redemption price in cash equal to the applicable Change of Control Purchase Price or Alternate Offer price, as applicable, plus, to the extent not included in the Change of Control Purchase Price or Alternate
Offer price, as applicable, accrued and unpaid interest, if any, to the date of redemption. 

  
 68 

 In connection with the purchase of Notes pursuant to a Change of Control Offer, the Issuer
shall (i) comply with all applicable securities legislation in the United States, including, without limitation, the tender offer rules under the Exchange Act that may then be applicable and (ii) file a Schedule TO or any other required
schedules under the Exchange Act; in each case, so as to permit the rights and obligations under this section to be exercised in the time and in the manner specified in this section. To the extent that the provisions of any applicable securities
laws or regulations conflict with this Section 4.13, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.13 by virtue of such compliance.

 The provisions under this Indenture relating to the Issuer’s obligation to make a Change of Control Offer may be waived, modified or
terminated with the written consent of the Holders of a majority in principal amount of the Notes then outstanding. 
 Notwithstanding
anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making of the
Change of Control Offer. 
 Section 4.14 Corporate Existence. Subject to Article V, the Issuer shall
do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the corporate, partnership, limited liability company or other existence of each of its Subsidiaries in accordance with the
respective organizational documents (as the same may be amended from time to time) of the Issuer or any such Subsidiary and the rights (charter and statutory), licenses and franchises of the Issuer and its Subsidiaries; provided that the
Issuer shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Subsidiaries, if the Issuer shall determine that the preservation thereof is no longer desirable in the
conduct of the business of the Issuer and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders. 

Section 4.15 Additional Guarantees. The Issuer shall cause any direct or indirect Domestic Subsidiary,
other than an Excluded Subsidiary, formed or acquired by the Issuer, within 30 days of such formation or acquisition, to execute and deliver to the Trustee a supplemental indenture in substantially the form attached hereto as Exhibit B,
pursuant to which such Domestic Subsidiary shall become a Guarantor with respect to the Notes, upon the terms and subject to the release provisions and other limitations set forth in Article X; provided that, in each case, recovery from any
Guarantor that is a FSHCO will be limited to 65% of the voting Equity Interests in any CFCs and FSCHOs owned by such Guarantor (and 100% of any other Equity Interest in any such entities along with all other assets of such Guarantor that is a FSHCO)
to the extent that such voting Equity Interests of such CFC or FSHCO would otherwise constitute Excluded Property. 

  
 69 

 Section 4.16 [Reserved].  

Section 4.17 Covenant Termination. 

(a) Following the first date that the Notes have a Moody’s rating of Baa3 or higher or an S&P rating of BBB- or higher and no Default or Event of Default has occurred and is then continuing, then upon delivery by the Issuer to the Trustee of an Officers’ Certificate to the foregoing effect, the Issuer and the
Subsidiaries will no longer be subject to the following covenants: 
 (1) Section 4.7; 

(2) Section 4.8; 

(3) Section 4.9; 

(4) Section 4.10; 

(5) Section 4.11; and

(b) Neither the Trustee nor any Agent shall have any obligation to monitor the ratings of the Notes or the occurrence or date
of the termination of the foregoing covenants and may rely conclusively on the Officers’ Certificates referred to above. Neither the Trustee nor any Agent shall have any obligation to notify the Holders of the occurrence or date of the
termination of the foregoing covenants, but the Trustee may provide a copy of such Officers’ Certificates to any Holder upon request.

 70 

 (B) the Person (if other than the Issuer) formed by or surviving or
continuing from such consolidation or merger or to which such sale, lease, transfer, conveyance or other disposition or assignment shall be made (collectively, the “Successor”) is a corporation, limited liability company or limited

co-obligor all of the obligations of the Issuer under this Indenture, the Security Documents and the Notes pursuant to a supplemental indenture to this Indenture executed and delivered to the Trustee; 

(2) immediately after giving effect to such transaction and the assumption of the obligations as set forth in clause (1)(B)
above and the incurrence of any Indebtedness to be incurred in connection therewith, and the use of any net proceeds therefrom on a pro forma basis, no Default shall have occurred and be continuing;

additional Indebtedness pursuant to the Coverage Ratio Exception or (ii) the Fixed Charge Coverage Ratio of the Issuer or its Successor, as the case may be, and its Subsidiaries would be greater than or equal to such Fixed Charge Coverage Ratio
immediately prior to such merger or consolidation;

instruments to be executed, delivered, filed and recorded, as applicable, in such jurisdictions as may be required by applicable law to preserve and protect the Lien of the Security Documents on the Collateral owned by or transferred to the
Successor; 
 (5) the Collateral owned by or transferred to the Successor shall (A) continue to constitute Collateral
under this Indenture and the Security Documents, (B) be subject to the Lien in favor of the Notes Collateral Agent for the benefit of the Trustee and the Holders of the Notes, and (C) not be subject to any Lien other than Permitted Liens;

 (6) the property and assets of the Person which is merged or consolidated with or into the Successor, to the extent that

assets to be made subject to the Lien of the Security Documents in the manner and to the extent required in this Indenture; and 

  
 71 

 (7) the Issuer shall have delivered to the Trustee and Notes Collateral
Agent an Officers’ Certificate and an Opinion of Counsel to the effect that such merger, consolidation or transfer and such agreement and/or supplemental indenture (if any) comply with this Indenture and the Security Documents and that this

Certificate and an Opinion of Counsel, each stating that such merger or consolidation and such agreements and/or supplemental indenture (if any) comply with this Indenture and the Security Documents and that this Indenture, the Notes, the Notes
Guarantee and the Security Documents, as applicable, constitute legal, valid and binding obligations of any Successor, as applicable, subject to customary exceptions; or 

  
 72 

 (2) the transaction is made in compliance with Section 4.10. 

For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise, in a single transaction or series of transactions) of all
or substantially all of the properties or assets of one or more Subsidiaries of the Issuer, the Equity Interests of which constitute all or substantially all of the properties and assets of the Issuer, will be deemed to be the transfer of all or

 (c) Upon any consolidation or merger of the Issuer or a
Guarantor, or any transfer of all or substantially all of the assets of the Issuer in accordance with the foregoing, in which the Issuer or such Guarantor is not the continuing obligor under the Notes or its Guarantee, as applicable, the surviving
entity formed by such consolidation or merger or into which the Issuer or such Guarantor is merged or the Person to which the sale, conveyance, lease, transfer, disposition or assignment is made will succeed to, and be substituted for, and may
exercise every right and power of, the Issuer or such Guarantor under this Indenture, the Notes, the Security Documents and the Note Guarantees with the same effect as if such surviving entity had been named therein as the Issuer or such Guarantor
and, except in the case of a lease, the Issuer or such Guarantor, as the case may be, will be released from the obligation to pay the principal of and interest on the Notes or in respect of its Note Guarantee, as the case may be, and all of the
Issuer’s or such Guarantor’s other obligations and covenants under the Notes, this Indenture, the Security Documents and its Note Guarantee, if applicable.

 Section 6.2 Acceleration. If
an Event of Default (other than an Event of Default specified in clause (8) or (13) of Section 6.1 with respect to the Issuer) shall have occurred and be continuing under this Indenture, the Trustee, by written notice to the Issuer, or the
Holders of at least 25.0% in aggregate principal amount of the Notes then outstanding by written notice to the Issuer and the Trustee, may declare (an “acceleration declaration”) all amounts owing under the Notes (including the
Redemption Premium)to be due and payable. Upon such acceleration declaration, the aggregate principal of, the Redemption Premium with respect to and accrued and unpaid interest on the outstanding Notes shall become due and payable immediately. 

  
 76 

 If an Event of Default specified in clause (8) or (13) of Section 6.1 occurs with
respect to the Issuer, then all unpaid principal of, the Redemption Premium, any other premiums (if any), and accrued and unpaid interest on all of the outstanding Notes shall ipso facto become and be immediately due and payable without any
declaration or other action or notice on the part of the Trustee or any Holder of the Notes to the extent permitted by applicable law. 

After such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of the
Notes then outstanding may rescind and annul such acceleration if: 
 (a) the rescission would not conflict with any judgment
or decree; 
 (b) all existing Events of Default have been cured or waived other than nonpayment of accelerated principal and
interest; 
 (c) to the extent the payment of such interest is lawful, interest on overdue installments of interest and
overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid; and 
 (d) the
Issuer has paid the Trustee its reasonable compensation and reimbursed the Trustee for its reasonable expenses, disbursements and advances. 

No such rescission shall affect any subsequent Default or impair any right consequent thereto. 

If the Notes are accelerated or otherwise become due prior to their maturity date as a result of an Event of Default or by operation of law or
a Premium Event occurs, the principal of, accrued and unpaid interest and premium on the Notes subject to such Premium Event shall be due and payable. If the Notes are accelerated or otherwise become due prior to their maturity date, in each case,
as a result of an Event of Default or by operation of law or any Premium Event occurs prior to August 4, 2024, the amount of principal of, accrued and unpaid interest and premium on the Notes that becomes due and payable shall equal the
redemption price applicable with respect to an optional redemption of the Notes, in effect on the date of such acceleration, Premium Event or the date on which the Notes otherwise become due as if such acceleration or other circumstance causing the
Notes to become due were an optional redemption of the Notes accelerated or becoming due (the “Redemption Premium”). In any such case, the Redemption Premium shall constitute part of the Note Obligations, and constitutes liquidated
damages, not unmatured interest or a penalty, as the actual amount of damages to the Holders as a result of the relevant Premium Event would be impracticable and extremely difficult to ascertain. 

  
 77 

 Accordingly, the Redemption Premium is provided by mutual agreement of the Issuer and the
Guarantors and the Holders as a reasonable estimation and calculation of such actual lost profits and other actual damages of such Holders. Without limiting the generality of the foregoing, it is understood and agreed that upon the occurrence of any
Premium Event, the Redemption Premium shall be automatically and immediately due and payable as though any Notes subject to a Premium Event were voluntarily prepaid as of such date and shall constitute part of the Note Obligations secured by the
Collateral. The Redemption Premium shall also be automatically and immediately due and payable if the Notes are satisfied or released by foreclosure (whether by power of judicial proceeding or otherwise), deed in lieu of foreclosure or by any other
means. THE ISSUER AND THE GUARANTORS HEREBY EXPRESSLY WAIVE (TO THE FULLEST EXTENT THEY MAY LAWFULLY DO SO) THE PROVISIONS OF ANY PRESENT OR FUTURE STATUTE OR OTHER LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF THE FOREGOING REDEMPTION
PREMIUM IN CONNECTION WITH ANY SUCH EVENTS, ANY RESCISSION OF SUCH ACCELERATION OR THE COMMENCEMENT OF ANY BANKRUPTCY OR INSOLVENCY EVENT. The Issuer and the Guarantors expressly agree (to the fullest extent it and they may lawfully do so) that with
respect to the Redemption Premium payable under the terms of this Indenture: (1) the Redemption Premium is reasonable and is the product of an arm’s length transaction between sophisticated business parties, ably represented by counsel;
(2) the Redemption Premium shall be payable notwithstanding the then-prevailing market rates at the time payment is made; (3) there has been a course of conduct between the Holders and the Issuer and the Guarantors giving specific
consideration in this transaction for such agreement to pay the Redemption Premium; and (4) the Issuer and the Guarantors shall be estopped hereafter from claiming differently than as agreed to in this paragraph. The Issuer and the Guarantors
expressly acknowledge that their agreement to pay the Redemption Premium as herein described is a material inducement to the Holders to purchase the Notes. 

Section 6.3 Other Remedies. The Trustee may pursue any available remedy to collect the payment of
principal, premium (including the Applicable Premium and Redemption Premium), if any, interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay
or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the
extent permitted by law. 
 Section 6.4 Waiver of Past Defaults. Subject to Section 9.2, the
Holders of a majority in aggregate principal amount of the Notes then outstanding by written notice to the Trustee and Notes Collateral Agent may, on behalf of the Holders of all of the Notes, waive any existing Default or Event of Default and its
consequences under this Indenture except a continuing Default or Event of Default in the payment of interest or premium (including the Applicable Premium and Redemption Premium) or the principal of, the Notes. 

Section 6.5 Control by Majority. The Holders of a majority in aggregate principal amount of the then
outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust power conferred on it. However, (a) the Trustee may refuse to follow any direction
that conflicts with law or this Indenture, that may involve the Trustee in personal liability, or that the Trustee 

  
 78 

 
determines in good faith may be unduly prejudicial to the rights of Holders not joining in the giving of such direction (it being understood that the Trustee does not have an affirmative duty to
ascertain whether or not any such direction is unduly prejudicial to the rights of such other Holders) and (b) the Trustee may take any other action it deems proper that is not inconsistent with any such direction received from the Holders.

 Section 6.6 Limitation on Suits. A Holder may pursue a remedy with respect to this Indenture or
the Notes only if: 
 (a) the Holder gives to the Trustee written notice of a continuing Event of Default; 

(b) the Holder or Holders of at least 25.0% in aggregate principal amount of outstanding Notes make a written request to the
Trustee to pursue the remedy; 
 (c) such Holder or Holders offer the Trustee indemnity satisfactory to the Trustee against
any costs, 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) during such 60-day period, the Holders
of a majority in aggregate principal amount of the outstanding Notes do not give the Trustee a direction that is inconsistent with the request. 

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder (it
being understood that the Trustee does not have an affirmative duty to ascertain whether or not any such use by a Holder prejudices the rights of any other Holders or obtains priority or preference over such other Holders). 

Section 6.7 Rights of Holders of Notes to Receive Payment. Notwithstanding any other provision of this
Indenture, the right of any Holder to receive payment of principal of, premium (including the Applicable Premium and Redemption Premium) or interest on, such Note or to bring suit for the enforcement of any such payment, on or after the due date
expressed in the Notes, shall not be impaired or affected without the consent of the Holder. 
 Section 6.8
Collection Suit by Trustee. If an Event of Default specified in clauses (1) or (2) of Section 6.1 occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust
against the Issuer for the whole amount of principal of, premium (including the Applicable Premium and Redemption Premium) and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, 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. 

  
 79 

 Section 6.9 Trustee May File Proofs of Claim. The
Trustee is authorized to 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 reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Issuer (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and
distribute any money or other securities or property payable or deliverable upon the conversion or exchange of the Notes or on any such claims, 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 7.7. To the extent that the payment of any such compensation, expenses, disbursements and advances to the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.7 out of the estate in any such proceeding, 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 properties that the Holders may be entitled to receive in such proceeding, whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing in this Section 6.9 shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the
claim of any Holder in any such proceeding. 
 Section 6.10 Priorities. If the Trustee collects any
money or property pursuant to this Article VI, it shall pay out the money and property in the following order: 
 First: to the
Trustee (acting in any capacity), the Notes Collateral Agent and their respective agents and attorneys for amounts due under Section 7.7, including payment of all reasonable compensation, expenses and liabilities incurred, and all advances
made, by it and the costs and expenses of collection; 
 Second: to Holders for amounts due and unpaid on the Notes for principal,
premium (including the Applicable Premium and Redemption Premium), if any, and interest ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium(including the Applicable
Premium and Redemption Premium), if any, and interest, respectively; 
 Third: without duplication, to the Holders for any other
Obligations owing to the Holders under this Indenture and the Notes; and 
 Fourth: to the Issuer or to 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 6.10. 
 Section 6.11 Undertaking for Costs. In any suit for the enforcement of any
right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as the 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, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by
the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.7, or a suit by Holders of more than 10.0% in principal amount of the then outstanding Notes.

 Article VII 

TRUSTEE 

Section 7.1 Duties of Trustee. 

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

subject to this Section 7.1. 
 Section 7.2 Rights of Trustee. 

(a) The Trustee may conclusively rely and shall be fully protected in acting or refraining from acting on any resolution,
certificate, statement, instrument, opinion, notice, report, request, direction, consent, order, bond, debenture or other document (whether in original or facsimile form) believed by it to be genuine and to have been signed or presented by the
proper Person. The Trustee need not investigate any fact or matter stated therein.

request or direction. 

  
 82 

 (g) The Trustee shall not be bound to make any investigation into the facts
or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or documents, but the Trustee, in its
discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine during normal business hours
the books, records and premises of the Issuer, personally or by agent or attorney at the sole cost of the Issuer, and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation. 

(h) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right
to be compensated and indemnified under this Article VII, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, to the Agents and to each other agent, custodian and Person employed to act hereunder. 

(i) The Trustee may request that the Issuer and each of the Guarantors shall deliver to the Trustee an Officers’
Certificate setting forth the names of individuals and/or titles of Officers of the Issuer and each Guarantor, as applicable, authorized at such time to take specified actions pursuant to this Indenture of the Issuer, the Notes and the Guarantees,
which Officers’ Certificate may be signed by any Person authorized to sign an Officers’ Certificate, including any Person specified as so authorized in any such certificate previously delivered and not superseded. 

(j) The Trustee shall not be deemed to have notice or be charged with knowledge of any Default or Event of Default unless a
Responsible Officer of the Trustee has actual knowledge thereof or the Trustee shall have received from the Issuer or any other obligor upon the Notes or from any Holder written notice thereof at its address set forth in Section 11.2 and such
notice references the Notes and this Indenture. In the absence of such actual knowledge or such notice, the Trustee may conclusively assume that no such Default or Event of Default exists. 

(k) In no event shall the Trustee be responsible or liable for special, indirect, punitive, or consequential loss or damage of
any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 

(l) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties
hereunder. 
 Section 7.3 Individual Rights of the Trustee. The Trustee in its individual or any
other capacity (including in its capacity as the Agent) may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any Affiliate of the Issuer with the same rights it would have if it were not Trustee. However, in the event
that the Trustee acquires any conflicting interest (as defined in the TIA), it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as Trustee or resign. Any Agent may do the same with like rights and duties. The
Trustee is also subject to Section 7.10 and Section 7.11. 

  
 83 

 Section 7.4 Trustee’s
Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Notes or any Guarantee, it shall not be accountable for the use of the proceeds from the Notes or any
money paid to the Issuer or upon the Issuer’s 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 Notes, any Officers’ Certificate delivered to the Trustee hereunder, or any other document in connection with the sale of the Notes or pursuant to this Indenture other than
the Trustee’s certificate of authentication hereunder. 
 Section 7.5 Notice of Defaults. If a
Default or Event of Default occurs and is continuing and if a Responsible Officer of the Trustee has notice or knowledge as provided in Section 7.2(j), the Trustee shall deliver to Holders a notice of the Default or Event of Default within 90
days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium (including the Applicable Premium and Redemption Premium), if any, or interest on any Note, the Trustee may withhold the notice if and so
long as the Board of Directors, the executive committee or a trust committee of directors or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interest of the Holders. 

Section 7.6 Reports by Trustee to Holders of the Notes. Within 60 days after each January 15
beginning with January 15, 2021, and for so long as Notes remain outstanding, the Trustee shall transmit to the Holders a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA §
313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA § 313(b). The Trustee shall also transmit by mail all reports as required by TIA § 313(c).

 A copy of each report at the time of its mailing to the Holders shall be mailed to the Issuer and filed with the SEC and each stock
exchange, if any, on which the Issuer has informed the Trustee in writing the Notes are listed in accordance with TIA § 313(d). The Issuer shall promptly notify the Trustee in writing when the Notes are listed on any stock exchange and of any
delisting thereof. 
 Section 7.7 Compensation and Indemnity. The Issuer shall pay to the Trustee
from time to time compensation for its acceptance of this Indenture and for all services rendered by it hereunder as agreed upon in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express
trust. The Issuer shall reimburse the Trustee, as applicable, promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the
reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel. 
 Each of the Issuer and the Guarantors,
jointly and severally, shall indemnify the Trustee (which for purposes of this Section 7.7 shall include its officers, directors, employees and agents) against any and all claims, damages, losses, liabilities, costs or expenses incurred by it
(including, without limitation, the fees and expenses of its agents and counsel) arising out of or in connection with the acceptance or administration of its duties under this Indenture, the performance of its obligations and/or exercise of its
rights hereunder, including the costs and expenses of enforcing this Indenture against the Issuer or any Guarantor (including this Section 

  
 84 

 
7.7) and defending itself against any claim (whether asserted by the Issuer or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or
duties hereunder, except to the extent any such loss, claim, damage, liability or expense shall be caused by its own gross negligence or willful misconduct as determined by a final, non-appealable judgment of
a court of competent jurisdiction. The Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Trustee may
have one separate counsel, and the Issuer shall pay the reasonable fees and expenses of such counsel for the Trustee. The Issuer need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. 

The obligations of the Issuer and the Guarantors under this Section 7.7 shall survive the satisfaction and discharge of this Indenture,
the payment of the Notes or the resignation or removal of the Trustee. 
 To secure the Issuer’s payment obligations in this
Section 7.7, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal or interest, if any, on particular Notes. Such Lien shall survive the
satisfaction and discharge of this Indenture, the payment of the Notes and the resignation or removal of the Trustee. 
 When the Trustee
incurs expenses or renders services after an Event of Default specified in Section 6.1(8) occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses
of administration under any Bankruptcy Law. 
 The Trustee shall comply with the provisions of TIA § 313(b)(2) to the extent
applicable. 
 Section 7.8 Replacement of Trustee. A resignation or removal of the Trustee and
appointment of a successor Trustee shall become effective only upon the successor trustee’s acceptance of appointment as provided in this Section 7.8. 

The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Issuer. The Holders of a
majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuer in writing not less than 30 days prior to the effective date of such removal. The Issuer may remove the Trustee if: 

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

(b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any
Bankruptcy Law; 
 (c) a custodian or public officer takes charge of the Trustee or its property; or 

(d) the Trustee becomes incapable of acting. 

  
 85 

 If the Trustee resigns or is removed or if a vacancy exists in the office of the Trustee for
any reason, the Issuer shall promptly appoint a successor trustee. Within one year after the successor trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor trustee to replace the
successor trustee appointed by the Issuer. 
 If a successor trustee does not take office within 30 days after the retiring Trustee resigns
or is removed, such retiring Trustee (at the expense of the Issuer), the Issuer or the Holders of at least 10.0% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor
trustee. 
 If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with
Section 7.10, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee. 

A successor trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the successor trustee shall have all the rights, powers and the duties of the Trustee under this Indenture. The successor trustee shall mail a notice of its succession to the
Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee; provided that all sums owing to such Trustee hereunder have been paid and subject to the Lien provided for in Section 7.7.
Notwithstanding replacement of the Trustee pursuant to this Section 7.8, the Issuer’s and the Guarantors’ obligations under Section 7.7 shall continue for the benefit of the retiring Trustee. 

Section 7.9 Successor Trustee by Merger, Etc. If the Trustee or any Agent consolidates, merges or
converts into, or transfers all or substantially all of its corporate trust business (including this transaction) to, another corporation, the successor corporation without any further act shall be the successor Trustee or any Agent, as applicable.

 Section 7.10 Eligibility; Disqualification. There shall at all times be a Trustee hereunder that
is a corporation organized and doing business under the laws of the United States or of any state thereof that is authorized under such laws to exercise corporate trustee power and that is subject to supervision or examination by federal or state
authorities. Such Trustee together with its affiliates shall at all times have a combined capital surplus of at least $50.0 million as set forth in its most recent annual report of condition. 

This Indenture shall always have a Trustee who satisfies the requirements of TIA §§ 310(a)(l), (2) and (5). Such Trustee is subject
to TIA § 310(b) including the provision in § 310(b)(1) and (3); provided that there shall be excluded from the operation of TIA § 310(b)(1) any indenture or indentures under which other securities, or conflicts of interest or
participation in other securities, of the Issuer or the Guarantors are outstanding if the requirements for exclusion set forth in TIA § 310(b)(1) are met. 

Section 7.11 Preferential Collection of Claims Against the Issuer. The Trustee is subject to TIA
§ 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein. 

  
 86 

 Article VIII 

DEFEASANCE; DISCHARGE OF THIS INDENTURE 

Section 8.1 Option to Effect Legal Defeasance or Covenant Defeasance. The Issuer may, by delivery of
an Officers’ Certificate, at any time, elect to have either Section 8.2 or Section 8.3 applied to all outstanding Notes upon compliance with the conditions set forth below in this Article VIII. 

Section 8.2 Legal Defeasance. Upon the Issuer’s exercise under Section 8.1 of the option
applicable to this Section 8.2, the Issuer shall, subject to the satisfaction of the conditions set forth in Section 8.4, be deemed to have been discharged from its obligations with respect to all outstanding Notes on the date the
conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuer and the Guarantors shall be deemed to have paid and discharged the entire Obligations represented
by the Notes, the Security Documents and the Note Guarantees, which shall thereafter be deemed to be outstanding only for the purposes of Section 8.5 and the other Sections of this Indenture referred to in (a) and (b) below, and to have
satisfied all of its other Obligations under such Notes, Note Guarantees and this Indenture (and the Trustee, on written demand of and at the expense of the Issuer, shall execute instruments acknowledging the same), and this Indenture shall cease to
be of further effect as to all such Notes and Note Guarantees, except for the following provisions which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Notes to receive payments in
respect of the principal of, and interest and premium (including the Applicable Premium and Redemption Premium) on such Notes when such payments are due from the trust funds referred to in Section 8.4(1); (b) the Issuer’s obligations with
respect to such Notes under Section 2.2, Section 2.3, Section 2.4, Section 2.6, Section 2.7, Section 2.10, and Section 4.2; (c) the rights, powers, trusts, duties and immunities of the Trustee or the Notes
Collateral Agent, including without limitation thereunder, under Section 7.7, Section 8.5 and Section 8.7 and the obligations of the Issuer and the Guarantors in connection therewith; and (d) the provisions of this Article VIII.
Subject to compliance with this Article VIII, the Issuer may exercise its option under this Section 8.2 notwithstanding the prior exercise of its option under Section 8.3. 

Section 8.3 Covenant Defeasance. Upon the Issuer’s exercise under Section 8.1 above of the
option applicable to this Section 8.3, the Issuer shall, subject to the satisfaction of the conditions set forth in Section 8.4 below, be released from its obligations under Section 4.3, Section 4.7, Section 4.8,
Section 4.9, Section 4.10, Section 4.11, Section 4.12, Section 4.13, Section 4.15, Section 4.16 and Section 5.1(a)(3) and the Security Documents on and after the date the conditions set forth below are
satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not outstanding for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed outstanding for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means
that, with respect to the outstanding Notes, the Issuer or any of its Subsidiaries may omit to comply with and shall have no liability 

  
 87 

 
in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of
any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.1, but, except as specified above, the remainder of this
Indenture and such Notes shall be unaffected thereby. 
 Section 8.4 Conditions to Legal or Covenant
Defeasance. The following shall be the conditions to the application of either Section 8.2 or Section 8.3 to the outstanding Notes: 

(1) the Issuer must irrevocably deposit with the Trustee, as trust funds, in trust solely for the benefit of the Holders, U.S.
dollars, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without consideration of any reinvestment of interest) in the opinion of a nationally recognized investment bank, appraisal firm or firm of
independent public accountants selected by the Issuer and delivered to the Trustee, to pay the principal of and interest on the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, 

(2) in the case of Legal Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that: 
 (A) the Issuer has received from, or there has been published by the
United States Internal Revenue Service, a ruling, or 
 (B) since the date of this Indenture, there has been a change in the
applicable U.S. federal income tax law, 
 in either case to the effect that, and based thereon, such Opinion of Counsel shall confirm that,
the Holders of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the
same times as would have been the case if such Legal Defeasance had not occurred, 
 (3) in the case of Covenant Defeasance,
the Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax
purposes as a result of the Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the Covenant Defeasance had not occurred, 

(4) no Default shall have occurred and be continuing on the date of such deposit (other than a Default resulting from the
borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowings), 

  
 88 

 (5) the Legal Defeasance or Covenant Defeasance shall not result in a breach
or violation of, or constitute a default under any other material agreement or instrument (other than this Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Issuer or any of its
Subsidiaries is a party or by which the Issuer or any of its Subsidiaries is bound, 
 (6) the Issuer shall have delivered to
the Trustee an Officers’ Certificate stating that the deposit was not made by it with the intent of preferring the Holders over any other of its creditors or with the intent of defeating, hindering, delaying or defrauding any other of its
creditors or others, and 
 (7) the Issuer shall have delivered to the Trustee an Officers’ Certificate and an Opinion
of Counsel to the effect that the conditions precedent provided for in clauses (1) through (6) of this Section 8.4 have been complied with. 

Section 8.5 Deposited Money and U.S. Government Obligations to Be Held in Trust; Other Miscellaneous
Provisions. Subject to Section 8.6, all U.S. dollar and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.5, the
“Deposit Trustee”) pursuant to Section 8.4 or Section 8.8 in respect of the outstanding Notes shall be held in trust, shall not be invested, and shall be applied by the Deposit Trustee in accordance with the provisions of
such Notes and this Indenture to the payment, either directly or through any Paying Agent (including the Issuer or any Subsidiary acting as Paying Agent) as the Deposit Trustee may determine, to the Holders of such Notes of all sums due and to
become due thereon in respect of principal, premium (including the Applicable Premium and Redemption Premium), if any, and interest but such money need not be segregated from other funds except to the extent required by law. 

The Issuer shall pay and indemnify the Deposit Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable U.S. Government Obligations deposited pursuant to Section 8.4 or Section 8.8 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law
is for the account of the Holders of the outstanding Notes. 
 Anything in this Article VIII to the contrary notwithstanding, the Deposit
Trustee shall deliver or pay to the Issuer from time to time upon the written request of the Issuer and be relieved of all liability with respect to any U.S. dollars or non-callable U.S. Government Obligations
held by it as provided in Section 8.4 or Section 8.8 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Deposit Trustee (which may be the
opinion delivered under Section 8.4(1)), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance or satisfaction and discharge, as the case may be. 

  
 89 

 Section 8.6 Repayment to Issuer. Subject to any
applicable abandoned property law, any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, premium (including the Applicable Premium and Redemption Premium), if any, or
interest on any Note and remaining unclaimed for two years after such principal and premium (including the Applicable Premium and Redemption Premium), if any, or interest has become due and payable shall be paid to the Issuer on its written request
or (if then held by the Issuer) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof; and all liability of the Trustee or such Paying Agent
with respect to such trust money, and all liability of the Issuer as trustee thereof, shall thereupon cease. 

Section 8.7 Reinstatement. If the Trustee or Paying Agent is unable to apply any U.S. dollars or U.S.
Government Obligations in accordance with Section 8.2, Section 8.3 or Section 8.8, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such
application, then the obligations of the Issuer and the Guarantors under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.2, Section 8.3 or Section 8.8 until such
time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.2, Section 8.3 or Section 8.8, as the case may be; provided, however, that, if the Issuer makes any payment of principal of,
premium (including the Applicable Premium and Redemption Premium), if any, or interest on any Note following the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from
the money held by the Trustee or Paying Agent. 
 Section 8.8 Discharge. This Indenture will be
discharged and will cease to be of further effect (except as to rights of registration of transfer or exchange of Notes which shall survive until all Notes have been canceled and the rights, protections and immunities of the Trustee) as to all
outstanding Notes when either: 
 (a) all the Notes that have been authenticated and delivered (except lost, stolen or
destroyed Notes which have been replaced or paid and Notes for whose payment money has been deposited in trust or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from this trust), have been delivered to
the Trustee for cancellation; or 
 (b) 

(1) all Notes not delivered to the Trustee for cancellation otherwise (A) have become due and payable, (B) will
become due and payable, or may be called for redemption, within one year or (C) have been called for redemption pursuant to Section 3.7 and, in any case, the Issuer has irrevocably deposited or caused to be deposited with the Trustee as
trust funds in trust solely for the benefit of the Holders, U.S. dollars, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without consideration of any reinvestment of interest) in the opinion of a
nationally recognized investment bank, appraisal firm or firm of independent public accountants selected by the Issuer and delivered to the Trustee to pay and discharge the entire Indebtedness (including all principal and accrued interest) on the
Notes not theretofore delivered to the Trustee for cancellation (provided that if such redemption is made as provided under Section 3.7(a), (x) the amount 

  
 90 

 
of cash in U.S. dollars, non-callable government securities, or a combination thereof, that must be irrevocably deposited will be determined using an
assumed Applicable Premium calculated as of the date of such deposit and (y) the depositor must irrevocably deposit or cause to be deposited additional money (any such additional money, the “Applicable Premium Deficit”) in trust on
the redemption date as necessary to pay the Applicable Premium as determined by such date) (it being understood that any discharge shall be subject to the condition subsequent that such Applicable Premium Deficit is in fact paid); provided, however,
that the Trustee shall have no liability whatsoever in the event that such Applicable Premium Deficit is not made after the Trustee has discharged this Indenture. Any Applicable Premium Deficit will be set forth in an Officers’ Certificate
delivered to the Trustee simultaneously with the deposit of such Applicable Premium Deficit that confirms that such Applicable Premium Deficit will be applied toward such redemption); 

(2) the Issuer has paid or caused to be paid all other sums payable by it under this Indenture; and 

(3) the Issuer has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward
the payment of the Notes at maturity or on the date of redemption, as the case may be. 
 In addition, the Issuer must deliver to the
Trustee an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent to satisfaction and discharge have been complied with. 

After the Notes are no longer outstanding, the Issuer’s and the Guarantors’ obligations in Section 7.7, Section 8.5 and
Section 8.7 shall survive any discharge pursuant to this Section 8.8. 
 After such delivery or irrevocable deposit and receipt of
the Officers’ Certificate and Opinion of Counsel, the Trustee, upon written request, shall acknowledge in writing the discharge of the Issuer’s obligations under the Notes and this Indenture except for those surviving obligations specified
above. 
 Article IX

adversely affect the rights of any Holder;

Guarantees, the Security Documents or the Notes, as evidenced by an Officers’ Certificate of the Issuer; or (2) to conform the text of this Indenture, the Security Documents or the Notes or any other such documents (in recordable form) as

(j) to provide for the issuance of Additional Notes or PIK Interest Notes in accordance with this Indenture;

(p) to provide for the succession of any parties to the Security Documents (and other amendments that are administrative or
ministerial in nature) in connection with an amendment, renewal, extension, substitution, refinancing, restructuring, replacement, supplement or other modification from time to time in accordance with the terms of this Indenture and the applicable
Security Documents. 
 The Holders of the Notes also will be deemed to have consented for purposes of this Indenture, the Security Documents
and the Intercreditor Agreement to the execution and delivery by the Trustee and Notes Collateral Agent of an Acceptable Junior Lien Intercreditor Agreement to the extent the Liens securing obligations held by such parties, and the incurrence of
Indebtedness with respect thereto, are permitted by this Indenture. 
 After an amendment under this Indenture becomes effective, the Issuer
shall deliver to Holders a notice briefly describing such amendment. However, the failure to give such notice to all Holders, or any defect therein, will not impair or affect the validity of the amendment. 

Section 9.2 With Consent of Holders of Notes. With the consent of the Holders of not less than a
majority in aggregate principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes), the Issuer, the Guarantors, the Trustee and
the Notes Collateral Agent, if applicable, may amend or supplement this Indenture, the Notes, any Note Guarantees or any Security Document, subject to Section 6.7, waive any existing Default or Event of Default or compliance with any provision
of this Indenture, the Notes or the Note Guarantees; provided, however, that no such amendment, supplement or waiver shall, without the consent of the Holder of each outstanding Note affected thereby (including, without limitation, consents

maturity of, the principal of any Note; 
 (b) reduce the rate of or extend the time for payment of interest on any Note;

 (c) reduce any premium (including the Applicable Premium) payable upon redemption of the Notes or change the date on which

purchase, exchange or repurchase of Notes (including pursuant to Section 4.10, Section 4.13 and Section 12.1) shall not be deemed a redemption of the Notes; 

(d) make any Note payable in money or currency other than that stated in the Notes; 

  
 93 

 (e) make any change in the Notes, the Indenture, the Note Guarantees, the
Intercreditor Agreement, or the other Security Documents (1) modifying the application of proceeds of the Collateral in a manner that would adversely affect the rights of Holders hereunder or thereunder, (2) that would adversely alter the
priority and/or the security interest of the Notes Collateral Agent on behalf of any Holders in the Collateral (including with respect to any other Notes) or (3) that would subordinate, in right of payment, any Notes or the Note Guarantees of
the Guarantors to any other Indebtedness of the Issuer or such Guarantors, including any other Notes; 
 (f) reduce the
percentage of Holders necessary to consent to an amendment or waiver to this Indenture or the Notes;

(k) modify obligations of the Issuer to make an offer to purchase upon a Change of Control or from the Excess Proceeds of any
Asset Sale if such modification was made after the occurrence of the applicable Change of Control or Asset Sale and prior to the closing of the related offer to purchase, if any, being made. 

In addition, any amendment to, or waiver of, the provisions of this Indenture or any Security Document that has the effect of releasing all or
substantially all of the Collateral from the Liens securing the Notes will require the consent of the Holders of at least 66 2/3% in aggregate principal amount of the Notes. 

It shall not be necessary for the consent of the Holders under this Section 9.2 to approve the particular form of any proposed amendment
or waiver, but it shall be sufficient if such consent approves the substance thereof. 
 Section 9.3
Compliance with Trust Indenture Act. Every amendment or supplement to this Indenture or the Notes or the Guarantees shall be set forth in an amended or supplemental indenture that complies with the TIA as then in effect. 

Section 9.4 Revocation and Effect of Consents. Until an amendment, supplement or waiver becomes
effective, a consent to it by a Holder of a Note is a continuing consent by the Holder and every subsequent Holder of that Note or portion of the Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent
is not made on the Note. However, any such Holder or subsequent Holder may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. When an
amendment, supplement or waiver becomes effective in accordance with its terms, it thereafter binds every Holder. 

  
 94 

 The Issuer may, but shall not be obligated to, fix a record date for determining which
Holders consent to such amendment, supplement or waiver. 
 Section 9.5 Notation on or Exchange of
Notes. The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuer in exchange for all Notes may issue and the Trustee shall authenticate new Notes that reflect the
amendment, supplement or waiver. 
 Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of
such amendment, supplement or waiver. 
 Section 9.6 Trustee and Notes Collateral Agent to Sign Amendments,
Etc. The Trustee and Notes Collateral Agent, if applicable, shall sign any amended or supplemental indenture authorized pursuant to this Article IX if the amendment or supplement does not adversely affect the rights, duties, liabilities or
immunities of the Trustee or the Notes Collateral Agent, if applicable. In signing or refusing to sign any amendment or supplemental indenture, the Trustee and the Notes Collateral Agent shall be provided with and (subject to Section 7.1) shall
be fully protected in relying upon an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amendment or supplemental indenture is authorized or permitted by this Indenture and that all conditions precedent thereto
have been met or waived. 
 Article X 

GUARANTEES 

Section 10.1 Guarantees. 

(a) Each Guarantor hereby jointly and severally, fully and unconditionally guarantees the Notes and obligations of the Issuer
hereunder and thereunder, and guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee, that: (1) the principal of and premium (including the Applicable Premium and Redemption Premium), if any, and
interest on the Notes shall be paid in full when due, whether at Stated Maturity, by acceleration, call for redemption or otherwise, together with interest on the overdue principal, if any, and interest on any overdue interest to the extent lawful,
and all other Obligations of the Issuer to the Holders or the Trustee under this Indenture or the Notes shall be paid in full or performed, all in accordance with the terms hereof and thereof; and (2) in case of any extension of time of payment
or renewal of any Notes or of any such other obligations, the same shall be paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise. Each of the Guarantees
shall be a guarantee of payment and not of collection. 
 (b) Each Guarantor hereby agrees that its obligations hereunder
shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof,
the recovery of any judgment against the Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. 

  
 95 

 (c) Each Guarantor hereby waives the benefits of diligence, presentment,
demand for payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer or any other Person, protest, notice and all demands whatsoever and covenants that
the Guarantee of such Guarantor shall not be discharged as to any Note or this Indenture except by complete performance of the obligations contained in such Note and this Indenture and such Guarantee. Each of the Guarantors hereby agrees that, in
the event of a Default in payment of principal or premium (including the Applicable Premium and Redemption Premium), if any, or interest on any Note, whether at its Stated Maturity, by acceleration, call for redemption, purchase or otherwise, legal
proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Note, subject to the terms and conditions set forth in this Indenture, directly against each of the Guarantors to enforce each such Guarantor’s Guarantee
without first proceeding against the Issuer or any other Guarantor. Each Guarantor agrees that if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from
exercising their respective rights to accelerate the maturity of the Notes, to collect interest on the Notes, or to enforce or exercise any other right or remedy with respect to the Notes, such Guarantor shall pay to the Trustee for the account of
the Holders, upon demand therefor, the amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders and any other amounts due and owing to the Trustee under
this Indenture. 
 (d) If any Holder or the Trustee is required by any court or otherwise to return to the Issuer or any
Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Issuer or any Guarantor, any amount paid by any of them to the Trustee or such Holder, the Guarantee of each of the Guarantors, to the extent
theretofore discharged, shall be reinstated in full force and effect. This paragraph (d) shall remain effective notwithstanding any contrary action which may be taken by the Trustee or any Holder in reliance upon such amount required to be
returned. This paragraph (d) shall survive the termination of this Indenture. 
 (e) Each Guarantor further agrees that,
as between each Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (A) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI for the purposes of the Guarantee of such
Guarantor, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (B) in the event of any acceleration of such obligations as provided in Article VI, such
obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the purpose of the Guarantee of such Guarantor. 

(f) Each Guarantor that makes a payment for distribution under its Guarantee is entitled upon payment in full of all guaranteed
obligations under this Indenture to seek contribution from each other Guarantor in a pro rata amount of such payment based on the respective net assets of all the Guarantors at the time of such payment in accordance with GAAP. 

  
 96 

 Section 10.2 Execution and Delivery of Guarantee. To
evidence its Guarantee set forth in Section 10.1, each Guarantor agrees that this Indenture or a supplemental indenture in substantially the form attached hereto as Exhibit B shall be executed on behalf of such Guarantor by an Officer of
such Guarantor (or, if an officer is not available, by a board member or director) on behalf of such Guarantor by manual or facsimile signature. Each Guarantor hereby agrees that its Guarantee set forth in Section 10.1 hereof shall remain in
full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes. In case the Officer, board member or director of such Guarantor whose signature is on this Indenture or supplemental indenture, as
applicable, no longer holds office at the time the Trustee authenticates any Note, the Guarantee shall be valid nevertheless. 
 The
delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee set forth in this Indenture on behalf of the Guarantors. 

Section 10.3 Severability. In case any provision of any Guarantee shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 

Section 10.4 Limitation of Guarantors’ Liability. Each Guarantor and
by its acceptance hereof each Holder confirms that it is the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the Uniform Fraudulent Conveyance
Act, the Uniform Fraudulent Transfer Act or any similar federal or state law or the provisions of its local law relating to fraudulent transfer or conveyance. To effectuate the foregoing intention, the Trustee, the Holders and Guarantors hereby
irrevocably agree that the obligations of such Guarantor under its Guarantee (other than a company that is a direct or indirect parent of the Issuer) shall be limited to the maximum amount that will not, after giving effect to all other contingent
and fixed liabilities of such Guarantor (including, without limitation, any guarantees under the Credit Agreement) and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other
Guarantor in respect of the obligations of such other Guarantor under its Guarantee, result in the obligations of such Guarantor under its Guarantee constituting a fraudulent conveyance, fraudulent preference or fraudulent transfer or otherwise
reviewable under applicable law. 
 Section 10.5 Releases. A Guarantor shall be released of any
Obligations under its Note Guarantee and this Indenture upon: 
 (a) any sale or other disposition of all or substantially
all of the assets of such Guarantor (by merger, consolidation or otherwise) to a Person that is not (either before or after giving effect to such transaction) the Issuer or a Subsidiary, if the sale or other disposition does not violate the
applicable provisions of this Indenture; 

  
 97 

 (b) any sale, exchange or transfer (by merger, consolidation or otherwise)
of the Equity Interests of such Guarantor after which the applicable Guarantor is no longer a Subsidiary, which sale, exchange or transfer does not violate the applicable provisions of this Indenture; 

(c) [reserved]; 

(d) [reserved]; 

(e) if the Issuer exercises its Legal Defeasance option or its Covenant Defeasance option pursuant to Section 8.2 or
Section 8.3 or if its Obligations under this Indenture are discharged in accordance with Section 8.8; or 
 (f)
dissolution of such Guarantor provided no Default or Event of Default has occurred that is continuing. 
 Upon delivery to the Trustee and
the Notes Collateral Agent of an Officers’ Certificate and an Opinion of Counsel to the effect that all conditions precedent to the release of a Guarantor’s Guarantee set forth in this Indenture have been satisfied, the Trustee and the
Notes Collateral Agent shall execute any documents reasonably requested by the Issuer in writing in order to evidence the release of any Guarantor from its obligations under its Note Guarantee and the Security Agreement. 

Any Guarantor not released from its obligations under its Note Guarantee shall remain liable for the full amount of principal of and interest
on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article X. 

Section 10.6 Benefits Acknowledged. Each Guarantor acknowledges that it will receive direct and
indirect benefits from the financing arrangements contemplated by this Indenture and that its guarantee and waivers pursuant to its Guarantee are knowingly made in contemplation of such benefits.

 Section 11.13 Table of Contents, Headings, Etc. The
Table of Contents, Cross-Reference Table and Headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part of this Indenture and shall in no way modify or restrict any
of the terms or provisions hereof. 
 Section 11.14 Acts of Holders. 

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be
given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing (or, with respect to Global Notes, otherwise in accordance
with the rules and procedures of the Depositary); and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to
the Issuer. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of Holders signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Issuer, if made in the manner provided in this Section 11.14. 

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a
witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to such officer the execution
thereof. Where such execution is by a signer acting in a capacity other than such signer’s individual capacity, such certificate or affidavit shall also constitute sufficient proof of such signer’s authority. The fact and date of the
execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient. 

(c) The ownership of Notes shall be proved by the register maintained by the Registrar hereunder. 

(d) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note shall bind
every future Holder of the same Note and the Holder of every Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Issuer in
reliance thereon, whether or not notation of such action is made upon such Note. 
 (e) If the Issuer shall solicit from the
Holders any request, demand, authorization, direction, notice, consent, waiver or other Act, the Issuer may, at its option, by or pursuant to a board resolution of the Issuer’s Board of Directors, fix in advance a record date for the
determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Issuer shall have no obligation to do so. If such a record date is fixed, such request, demand,

  
 102 

 
authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be
deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of outstanding Notes have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and
for that purpose the outstanding Notes shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant
to the provisions of this Indenture not later than six months after the record date. 
 Section 11.15 Force
Majeure. In no event shall the Trustee or Agent be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including,
without limitation, fire, riots, strikes, or stoppages for any reason, embargoes, governmental actions, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or
malfunctions of utilities, communications or computer (software and hardware) services, it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the U.S. banking industry to resume performance
as soon as practicable under the circumstances. 
 Section 11.16 Legal Holidays. If any scheduled
payment date with respect to the Notes falls on a day that is not a Business Day, the payment to be made on such payment date will be made on the next succeeding Business Day with the same force and effect as if made on such payment date, and no
additional interest will accrue solely as a result of such delayed payment. 
 Section 11.17 Calculations in
Respect of the Notes. Except as otherwise provided above, the Issuer will be responsible for making all calculations called for under the Notes and this Indenture. These calculations include, but are not limited to, determinations of the
sales prices of the Common Stock, the Daily VWAPs, accrued interest payable on the Notes and the Conversion Rate of the Notes. The Issuer will make all these calculations in good faith and, absent manifest error, its calculations will be final and
binding on Holders of Notes. The Issuer will provide a schedule of its calculations to each of the Trustee and the Conversion Agent, and each of the Trustee and the Conversion Agent is entitled to rely conclusively upon the accuracy of the
Issuer’s calculations without independent verification. The Trustee will forward the Issuer’s calculations to any Holder of Notes upon the request of that Holder. In no event shall the Trustee, Registrar or Conversion Agent have any
responsibility for any calculations called for under the Notes or this Indenture. Neither the Trustee nor the Conversion Agent shall have any responsibility or obligation to determine when and if any Notes may be converted at any time or to notify
the Issuer, DTC or any Holder of Notes if the Notes have become convertible. 
 Section 11.18 USA Patriot
Act. The parties hereto acknowledge that in order to help the government fight the funding of terrorism and money laundering activities, pursuant to federal regulations that became effective on October 1, 2003, Section 326 of the
USA PATRIOT Act requires all financial institutions to obtain, verify, and record information that identifies each person establishing a relationship or opening an account with the Trustee. The parties hereto agree that they will provide the Trustee
with name, address, tax identification number, if applicable, and other information that will allow the Trustee to identify the individual or entity who is establishing the relationship, and will further provide the Trustee with formation documents
such as articles of incorporation or other identifying documents.

CONVERSION 

Section 12.1 Optional Conversion. 

(a) (1) On the second scheduled Trading Day prior to the date of any redemption pursuant to Section 3.7 each Holder
shall have the right, at such Holder’s option, to convert the Applicable Percentage of such Holder’s Notes that have been called for redemption (or a portion thereof if the portion to be converted is a minimum of $1.00 in principal amount
or an integral multiple thereof) into Common Stock and (2) on the second scheduled Trading Day prior to the maturity date of the Notes, each Holder shall have the right, at such Holder’s option, to convert the Applicable Percentage of such
Holder’s outstanding Notes (or a portion thereof if the portion to be converted is a minimum of $1.00 in principal amount or an integral multiple thereof) into Common Stock (any conversion pursuant to clause (1) or clause (2) of this
paragraph, an “Optional Conversion” and the date of any such conversion, an “Optional Conversion Date”); in each case, at a conversion rate (subject to adjustment as described below, the “Conversion
Rate”) of 740.7407 shares of Common Stock per $1,000 principal amount of Notes (equal to an initial Conversion Price of $1.35 per share of Common Stock). 

(b) At least 30 days prior to any Optional Conversion Date, the Issuer shall deliver, or cause to be delivered, to the Holders,
with a copy to the Trustee and the Conversion Agent (if other than the Trustee), a notice (an “Optional Conversion Notice”): 

(1) offering to exchange, pursuant to the procedures required by this Indenture and described in the Optional Conversion Notice
(an “Optional Conversion Offer”), on the Optional Conversion Date, all Notes properly tendered by any Holder pursuant to such Optional Conversion Offer prior to 5:00 p.m. New York time on the second scheduled Trading Day immediately
preceding the Optional Conversion Date for: 
 (A) in the case of an Optional Conversion in connection with a redemption,
(i) in respect of the Applicable Percentage of the principal amount of any such tendered Notes that were called for redemption, a number of shares of Common Stock per $1,000 principal amount of such Notes equal to the Conversion Rate then in
effect (plus cash in lieu of fractional shares); (ii) an amount of cash equal to the redemption price of (x) the principal amount of any such tendered Notes that were called for redemption, minus (y) the principal amount of Notes for which
Common Stock shall be issued pursuant to clause (A)(i) above; (iii) new Notes equal in principal amount to any such tendered Notes that were not called for redemption; and (iv) an amount of cash equal to accrued and unpaid

  
 104 

 
interest on such tendered Notes that were called for redemption to, but not including, the date of redemption; provided, that if the redemption date occurs on or after an interest record date but
on or prior to the related Interest Payment Date, then accrued and unpaid interest, if any, shall not be paid in connection with the Optional Conversion but shall be paid to the Person in whose name such Note was registered at the close of business
on such record date; and 
 (B) in the case of an Optional Conversion at the maturity of the Notes, (i) in respect of
the Applicable Percentage of the principal amount of such tendered Notes, a number of shares of Common Stock per $1,000 principal amount of such Notes equal to the Conversion Rate then in effect (plus cash in lieu of fractional shares); (ii) an
amount of cash equal to (x) the principal amount of such tendered Notes, minus (y) the principal amount of Notes for which Common Stock shall be issued pursuant to clause (B)(i) above; and (iii) to the extent no interest payment will
be made on such tendered Notes on the maturity date of the Notes, an amount of cash equal to accrued and unpaid interest to, but not including, the maturity date of the Notes; 

(2) describing the procedures, as determined by the Issuer, consistent with this Indenture and the applicable procedures of
DTC, that Holders must follow to accept the Optional Conversion Offer; and 
 (3) stating that interest shall cease to accrue
on any Notes that are called for redemption on the applicable Optional Conversion Date. 
 (c) For purposes of this section,
in determining (1) whether the Issuer is required to make an Optional Conversion Offer or (2) the portion of any tendered Notes that have been called for redemption, a pro rata portion of all outstanding Notes (based on the aggregate
principal amount of Notes for which the Issuer has delivered a notice of redemption) shall be deemed to have been called for redemption. 

(d) On or before the Optional Conversion Date, the Issuer shall deposit with the Paying Agent an amount equal to the cash
consideration to be paid in respect of the Notes or portions of Notes properly tendered. 
 (e) On the Optional Conversion
Date, the Issuer shall: 
 (1) accept for exchange all Notes or portions of Notes (of a minimum of $1.00 or integral
multiples of $1.00 in excess thereof) properly tendered pursuant to the Optional Conversion Offer; 
 (2) deliver or cause to
be delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being exchanged by the Issuer; and 

  
 105 

 (3) deliver to each Holder who has so tendered Notes, through the
Issuer’s transfer agent, a number of shares of Common Stock calculated as set forth in the Optional Conversion Notice. 

(f) The Paying Agent shall promptly deliver to each Holder who has so tendered Notes an amount of cash calculated as set forth
in the Optional Conversion Notice and the Trustee shall promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note in a principal amount calculated as set forth in the Optional Conversion Notice; provided
that each such new Note shall be in a minimum principal amount of $1.00 or integral multiples of $1.00 in excess thereof. 

(g) An Optional Conversion Offer will be required to remain open for at least 20 Business Days or for such longer period as is
required by law. 
 (h) In connection with the exchange of Notes pursuant to an Optional Conversion Offer, the Issuer shall
(1) comply with all applicable securities legislation in the United States, including, without limitation, the tender offer rules under the Exchange Act that may then be applicable and (2) file a Schedule TO or any other required schedules
under the Exchange Act; in each case, so as to permit the rights and obligations under this section to be exercised in the time and in the manner specified in this section. To the extent that the provisions of any applicable securities laws or
regulations conflict with this Section 12.1, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 12.1 by virtue of such compliance. 

(i) The Issuer shall not issue fractional shares of Common Stock upon an Optional Conversion. Instead, the Issuer shall pay the
cash value of such fractional shares based upon the closing sale price of the Common Stock on the Trading Day immediately preceding the Optional Conversion Date as set forth in clauses (1)(A)(i) and (1)(B)(i) of Section 12.1(b). 

Section 12.2 Mandatory Conversion. 

(a) Subject to the satisfaction of the Equity Conditions, the Issuer shall convert (a “Mandatory Conversion”)
a principal amount of Notes equal to the Applicable Percentage of the aggregate principal amount of Notes then outstanding, on a pro rata basis among all outstanding Notes, into a number of shares of Common Stock per $1,000 principal amount of Notes
to be converted equal to the Conversion Rate then in effect (plus cash in lieu of fractional shares) if the average of the Daily VWAPs of the Common Stock for any 20 consecutive Trading Day period exceeds or is equal to the Threshold Price then in
effect (a “Mandatory Conversion Event”). Upon the occurrence of a Mandatory Conversion Event, the Issuer shall deliver a notice (a “Mandatory Conversion Notice”) to the Holders, the Trustee and the Conversion Agent
(if other than the Trustee) not later than the open of business on the second Business Day following such Mandatory Conversion Event, which notice shall specify the date on which the Mandatory Conversion shall occur, which date shall not be later
than the second Business Day following delivery of such Mandatory Conversion Notice (the “Mandatory Conversion Date”). 

  
 106 

 (b) Notwithstanding the foregoing, a Mandatory Conversion shall not occur
if, as evidenced by an Officers’ Certificate delivered to the Trustee and the Conversion Agent (if other than the Trustee) on the Mandatory Conversion Date, all of the conditions listed below (the “Equity Conditions”) are not
satisfied on each day during the period (1) commencing on, and including, the date of the Mandatory Conversion Notice and (2) ending on, and including, the Mandatory Conversion Date. The Equity Conditions are as follows: 

(1) either (A) all shares of Common Stock issuable upon conversion of the Notes and held by a non-Affiliate of the Issuer shall be eligible for resale without the need for registration under any applicable federal or state securities laws or (B) a shelf registration statement registering the resale of
the shares of Common Stock issuable upon conversion of the Notes has been filed by the Issuer and been declared effective by the SEC or is automatically effective and is available for use, and the Issuer expects such shelf registration statement to
remain effective and available for use from the Mandatory Conversion Date until thirty days following the Mandatory Conversion Date; 

(2) the Common Stock to be delivered on such conversion is listed or traded on The New York Stock Exchange, The NASDAQ Global
Select Market, The NASDAQ Global Market, or any of their respective successors (each, an “Eligible Market”) and shall not then be suspended from trading on such Eligible Market; 

(3) at or prior to the Mandatory Conversion Date, for any Notes validly surrendered for Optional Conversion on or prior to the
date of the Mandatory Conversion Notice, the Issuer shall have delivered the number of shares of Common Stock and paid the amount of cash, if any, due upon conversion of such Notes to the applicable Holders; and 

(4) no Event of Default shall have occurred and be continuing. 

(c) The Issuer shall not issue fractional shares of Common Stock upon a Mandatory Conversion. Instead, the Issuer shall pay the
cash value of such fractional shares based upon the closing sale price of the Common Stock on the Trading Day immediately preceding the Mandatory Conversion Date. 

(d) Interest shall cease to accrue on any Notes that are converted on the Mandatory Conversion Date. 

(e) In connection with a Mandatory Conversion, the Issuer shall deliver to the Holder of the Notes, through the Issuer’s
transfer agent, a number of shares of Common Stock per $1,000 of principal amount of Notes being converted equal to the Conversion Rate in effect on the applicable Mandatory Conversion Date (plus cash in lieu of fractional shares). Accrued and
unpaid interest to, but not including, the 

  
 107 

 
Mandatory Conversion Date with respect to Notes that are converted will be payable in cash on the settlement date of the conversion; provided that if a Mandatory Conversion Date for any Notes
that are converted occurs during the period from the close of business on the record date for any interest payment to the open of business on the immediately following Interest Payment Date, then (1) accrued and unpaid interest, if any, on such
Notes will not be payable in cash on the settlement date of such conversion, (2) the Issuer shall reduce the number of shares of Common Stock otherwise deliverable to the Holder of such Notes as a result of such conversion by a number of shares
of Common Stock equal in value to the amount of interest that would have accrued on such Notes for the period commencing on such Mandatory Conversion Date to (but not including) the immediately following Interest Payment Date if such Notes had not
been converted and remained outstanding during such period (the value of a share of Common Stock for purposes of determining such number of shares of Common Stock to be equal to the average of the Daily VWAPs of the Common Stock for the 20
consecutive Trading Day period ending on the date on which the applicable Mandatory Conversion Event occurs), and (3) the full amount of interest payable with respect to such Notes (assuming that such Notes remained outstanding to such Interest
Payment Date) will be payable in full in cash on such Interest Payment Date to the Holder in whose name such Notes are registered at the close of business on such record date. Settlement shall occur on the second Business Day immediately following
the applicable Mandatory Conversion Date. 
 Section 12.3 Conversion Generally. 

(a) The Trustee shall initially act as conversion agent with respect to the Notes (the “Conversion Agent”).
Neither the Trustee nor the Conversion Agent (if other than the Trustee) shall have any duty to determine or verify the Issuer’s determination of whether any of the conditions to conversion have been satisfied or to notify the Holders of such.

 (b) The Issuer shall pay any documentary, stamp or similar issue or transfer tax or duty due on the issue, if any, of the
Common Stock upon the conversion of a Note. However, such Holder shall pay any such tax or duty that is due because such shares are issued in a name other than such Holder’s name. The Conversion Agent may refuse to deliver a certificate
representing the Common Stock to be issued in a name other than such Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax or duty which will be due because such shares are to be issued in a name other than such
Holder’s name. 
 (c) The converting Holder shall also provide or cause to be provided to the Trustee and the Conversion
Agent (if other than the Trustee) all information necessary to allow the Trustee and the Conversion Agent (if other than the Trustee) to comply with any applicable tax reporting obligations, including without limitation any cost basis reporting
obligations under IRC Section 6045. The Trustee and the Conversion Agent (if other than the Trustee) may rely on information provided to it and shall have no responsibility whatsoever to verify or ensure the accuracy of such information. 

  
 108 

 (d) A Note shall be deemed to have been converted on the relevant Conversion
Date. 
 (e) In case any Note shall be partially converted, the Issuer shall execute and the Trustee shall authenticate and
deliver to or upon the written order of the Holder of such Note a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note, without payment of any service charge by the
converting Holder but, if required by the Issuer or Trustee, with payment of a sum sufficient to cover any documentary, stamp or similar issue or transfer tax or similar governmental charge required by law or that may be imposed in connection
therewith as a result of the name of the Holder of the new Notes issued upon such conversion being different from the name of the Holder of the old Notes surrendered for such conversion. 

(f) Except as provided in Section 12.4, no adjustment shall be made for dividends on any shares of Common Stock issued
upon the conversion of any Note as provided in this Article XII. 
 (g) Upon the conversion of an interest in a Global Note,
the Trustee, or the Note Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. 

(h) The Person in whose name the shares of Common Stock shall be issuable upon conversion shall be treated as a stockholder of
record as of the close of business on the relevant Conversion Date. Upon a conversion of Notes, such Person shall no longer be a Holder of such converted Notes. 

Section 12.4 Adjustments to Conversion Rate. The Conversion Rate shall be adjusted as described below,
except that the Issuer shall not make any adjustments to the Conversion Rate if Holders participate (other than in the case of (x) a share split or share combination or (y) a tender or exchange offer), at the same time and upon the same
terms as holders of Common Stock and solely as a result of holding the Notes, in any of the transactions described below without having to convert their Notes as if they held a number of shares of Common Stock equal to the Conversion Rate,
multiplied by the principal amount (expressed in thousands) of Notes held by such Holder. 
 (a) If the Issuer exclusively
issues shares of Common Stock as a dividend or distribution on shares of the Common Stock, or if the Issuer effects a share split or share combination, the Conversion Rate shall be adjusted based on the following formula: 

CR1 = CR0 x OS1 

                      OS0 
 where, 
  

	 	CR0  =	 the Conversion Rate in effect immediately prior to the open of business on the
Ex-Dividend Date of such dividend or distribution, or immediately prior to the open of business on the effective date of such share split or share combination, as applicable; 

  
 109 

	 	CR1  =	 the Conversion Rate in effect immediately after the open of business on such
Ex-Dividend Date or effective date, as applicable; 

  

	 	OS0  =	 the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or effective date (before giving effect to any such dividend, distribution, share split or share combination), as applicable; and 

 

	 	OS1  =	 the number of shares of Common Stock outstanding immediately after giving effect to such dividend,
distribution, share split or share combination, as applicable. 

 Any adjustment made under this
Section 12.4(a) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the effective date for
such share split or share combination, as applicable. If any dividend or distribution of the type described in this Section 12.4(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the
date the Board of Directors of the Issuer or a committee thereof determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 

(b) If the Issuer distributes to all or substantially all holders of Common Stock any rights, options or warrants (other than
pursuant to a stockholder rights plan) entitling them, for a period of not more than 60 calendar days after the announcement date of such distribution, to subscribe for or purchase shares of the Common Stock at a price per share that is less than
the average of the last reported sale prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such distribution, the Conversion Rate shall be
increased based on the following formula: 
 CR1 = CR0 x OS0 + X 

                      OS0 + Y 
 where, 
  

	 	CR0  =	 the Conversion Rate in effect immediately prior to the open of business on the
Ex-Dividend Date for such distribution; 

  

	 	CR1  =	 the Conversion Rate in effect immediately after the open of business on such
Ex-Dividend Date; 

  

	 	OS0  =	 the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date; 

  
 110 

	 	X  =	 the total number of shares of Common Stock distributable pursuant to such rights, options or warrants; and

  

	 	Y  =	 the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or
warrants, divided by the average of the last reported sale prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the distribution of such
rights, options or warrants. 

 Any increase made under this Section 12.4(b) shall be made
successively whenever any such rights, options or warrants are distributed and shall become effective immediately after the open of business on the Ex-Dividend Date for such distribution. To the extent that
shares of Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the distribution of such
rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so distributed, the Conversion Rate shall be decreased to the Conversion Rate
that would then be in effect if such Ex-Dividend Date for such distribution had not occurred. 

For the purpose of this Section 12.4(b), in determining whether any rights, options or warrants entitle holders of Common
Stock to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the last reported sales prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day
immediately preceding the announcement of the distribution of such rights, options or warrants, and in determining the aggregate price payable to exercise such rights, options or warrants, there shall be taken into account any consideration received
by the Issuer for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Issuer in good faith. 

(c) If the Issuer distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the
Issuer or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of Common Stock, excluding: 

(1) dividends, distributions or issuances as to which an adjustment was effected pursuant to Section 12.4(a) or
Section 12.4(b) above; 
 (2) except as otherwise described below, rights issued pursuant to any stockholder rights plan
of the Issuer then in effect; 
 (3) distributions of Reference Property issued in exchange for, or upon conversion of, the
Common Stock as described in Section 12.7; 

  
 111 

 (4) dividends or distributions paid exclusively in cash as to which the
provisions set forth in Section 12.4(d) below shall apply; and 
 (5) Spin-Offs as to which the provisions set forth
below in this Section 12.4(c) shall apply; 
 then the Conversion Rate shall be increased based on the following
formula: 
 CR1 =
CR0    x     SP0 

                        
        SP0 – FMV 

where, 
  

	 	CR0  =	 the Conversion Rate in effect immediately prior to the open of business on the
Ex-Dividend Date for such distribution; 

  

	 	CR1  =	 the Conversion Rate in effect immediately after the open of business on such
Ex-Dividend Date; 

  

	 	SP0  =	 the average of the Daily VWAPs of the Common Stock over the 10 consecutive Trading Day period ending on, and
including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and 

  

	 	FMV  =	 the fair market value (as determined by the Issuer in good faith) of the shares of Capital Stock, evidences of
indebtedness, assets, property, rights, options or warrants distributed with respect to each outstanding share of the Common Stock on the Ex-Dividend Date for such distribution. 

Any increase made under the portion of this Section 12.4(c) above shall become effective immediately after the open of
business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such
distribution had not been declared. 
 Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or
greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder shall receive, in respect of the Applicable Percentage of each $1,000 principal amount of Notes held by such Holder, at the same time and upon the same
terms as holders of Common Stock, the amount and kind of the Issuer’s Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire the Issuer’s Capital Stock or other securities that such
Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution. 

  
 112 

 With respect to an adjustment pursuant to this Section 12.4(c) where
there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar Equity Interests, of or relating to a Subsidiary or other business unit of the Issuer, that are, or, when
issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula: 

CR1 = CR0 x     FMV0 + MP0 

                        
        MP0 
 where, 

 

	 	CR0  =	 the Conversion Rate in effect immediately prior to the end of the Valuation Period (as defined below);

  

	 	CR1  =	 the Conversion Rate in effect immediately after the end of the Valuation Period; 

 

	 	FMV0  =	 the average of the Daily VWAPs of the Capital Stock or similar Equity Interests distributed to holders of the
Common Stock applicable to one share of the Common Stock (determined by reference to the definition of Daily VWAP as if references therein to the Common Stock were to such Capital Stock or similar Equity Interests) over the first 10 consecutive
Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and 

 

	 	MP0  =	 the average of the Daily VWAPs of the Common Stock over the Valuation Period. 

The increase to the Conversion Rate under the preceding paragraph shall occur at the close of business on the last Trading Day
of the Valuation Period; provided that if the relevant Conversion Date occurs during the Valuation Period, the reference to “10” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed
from, and including, the Ex-Dividend Date for such Spin-Off to, but excluding, such Conversion Date in determining the Conversion Rate. If any dividend or distribution
that constitutes a Spin-Off is declared but not so paid or made, the Conversion Rate shall be immediately decreased, effective as of the date the Board of Directors of the Issuer or a committee thereof
determines not to pay or make such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared or announced. 

(d) If the Issuer makes any cash dividend or distribution to all or substantially all holders of Common Stock, the Conversion
Rate shall be increased based on the following formula: 
 CR1 = CR0 x     SP0     

                    SP0 – C 
 where, 

  
 113 

	 	CR0  =	 the Conversion Rate in effect immediately prior to the open of business on the
Ex-Dividend Date for such dividend or distribution; 

  

	 	CR1  =	 the Conversion Rate in effect immediately after the open of business on the
Ex-Dividend Date for such dividend or distribution; 

  

	 	SP0  =	 the Daily VWAP of the Common Stock on the Trading Day immediately preceding the
Ex-Dividend Date for such    dividend or distribution; and 

  

	 	C  =	 the amount in cash per share of Common Stock the Issuer distributes to all or substantially all holders of the
Common Stock. 

 Any increase made under this Section 12.4(d) shall become effective immediately after
the open of business on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of
Directors of the Issuer or a committee thereof determines not to make or pay such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing,
if “C” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder shall receive, for the Applicable Percentage of each $1,000 principal amount of Notes it holds, at the
same time and upon the same terms as holders of shares of the Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of the Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for such cash dividend or distribution. 
 (e) If the Issuer or any of its
Subsidiaries make a payment in respect of a tender or exchange offer for the Common Stock that is subject to the then applicable tender offer rules under the Exchange Act (other than any odd lot tender offer pursuant to Rule 13e-4(h)(5) under the Exchange Act), and the cash and value of any other consideration included in the payment per share of Common Stock exceeds the average of the Daily VWAPs of the Common Stock over the 10
consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall be increased based on the
following formula: 
 CR1 = CR0    x    AC + (SP1 x OS1) 

                        
    OS0 x SP1 

where, 
  

	 	CR0  =	 the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately
following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; 

  
 114 

	 	CR1  =	 the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately
following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; 

  

	 	AC  =	 the aggregate value of all cash and any other consideration (as determined by the Issuer in good faith) paid or
payable for shares of Common Stock purchased in such tender or exchange offer; 

  

	 	OS0  =	 the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer
expires (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer); 

  

	 	OS1  =	 the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer
expires (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer); and 

  

	 	SP1  =	 the average of the Daily VWAPs of the Common Stock over the 10 consecutive Trading Day period commencing on,
and including, the Trading Day next succeeding the date such tender or exchange offer expires. 

 The
increase to the Conversion Rate under the preceding paragraph shall occur at the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided
that if the relevant Conversion Date occurs during the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references to “10” or “10th” in the
preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding such expiration date of such tender or exchange offer to, but excluding, such Conversion Date
in determining the Conversion Rate. 
 If the Issuer is obligated to purchase shares of Common Stock pursuant to any such
tender or exchange offer described in this Section 12.4(e) but is permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the Conversion Rate shall be readjusted to be the Conversion Rate
that would then be in effect if such tender or exchange offer had not been made or had been made only in respect of the purchases that have been made. 

(f) Notwithstanding the foregoing, if a Conversion Rate adjustment becomes effective on any
Ex-Dividend Date as described above, and a Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related Record Date would be
treated as the record holder of shares of Common Stock as of the related Conversion Date based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the foregoing Conversion Rate
adjustment provisions, the 

  
 115 

 
Conversion Rate adjustment relating to such Ex-Dividend Date will not be made for such converting Holder. Instead, such Holder shall be treated as if such
Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment. 

(g) Except as stated herein, the Issuer shall not adjust the Conversion Rate for the issuance of shares of Common Stock or any
securities convertible into or exchangeable for shares of Common Stock or the right to purchase shares of Common Stock or such convertible or exchangeable securities. 

(h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 12.4, and subject
to applicable exchange listing rules, the Issuer is permitted to increase the Conversion Rate of the Notes by any amount for a period of at least 20 Business Days if the Issuer determines that such increase would be in its best interest. Subject to
applicable exchange listing rules, the Issuer may also (but is not required to) increase the Conversion Rate to avoid or diminish income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a dividend or
distribution of shares (or rights to acquire shares) or similar event. 
 (i) If the Issuer has a rights plan in effect upon
conversion of the Notes into Common Stock, Holders will receive, in addition to any shares of Common Stock received in connection with such conversion, the rights under the rights plan. However, if, prior to any conversion, the rights have separated
from the shares of Common Stock or the rights have become exercisable in accordance with the provisions of the applicable rights plan, the Conversion Rate shall be adjusted at the time of separation or upon the occurrence of such triggering event as
if the Issuer distributed to all or substantially all holders of Common Stock, shares of the Issuer’s Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants as described in Section 12.4(c), subject to
readjustment in the event of the expiration, termination or redemption of such rights. 
 (j) Notwithstanding any of the
foregoing, the Conversion Rate shall not be adjusted: 
 (1) upon the issuance of shares of Common Stock at a price below the
Conversion Price or otherwise, other than any such issuance described in clauses (a), (b) or (c) of this Section 12.4; 

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

(3) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or
future employee, director or consultant benefit or incentive plan or program of or assumed by the Issuer or any of its Subsidiaries; 

  
 116 

 (4) upon the issuance of any shares of Common Stock pursuant to any option,
warrant, right or exercisable, exchangeable or convertible security not described in the preceding bullet and outstanding as of the date the Notes were first issued; 

(5) for a third-party tender offer by any party other than a tender offer by one or more of the Issuer’s subsidiaries as
described in Section 12.4(e); 
 (6) upon the repurchase of any shares of Common Stock pursuant to an open market share
purchase program or other buy-back transaction, including structured or derivative transactions such as accelerated share repurchase transactions or similar forward derivatives, or other buy-back transaction, that is not a tender offer or exchange offer of the kind described under Section 12.4(e) above; 

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

(8) for accrued and unpaid interest, if any. 

(k) Adjustments to the Conversion Rate shall be calculated to the nearest 1/10,000th of a share. 

(l) If an adjustment to the Conversion Rate otherwise required by the provisions described above would result in a change of
less than 1% to the Conversion Rate, then, notwithstanding the foregoing, the Issuer may, at its election, defer and carry forward such adjustment, except that all such deferred adjustments must be given effect immediately upon the earlier to occur
of the following: (1) when all such deferred adjustments would result in an aggregate change of at least 1% to the Conversion Rate and (2) on the Conversion Date for any Notes. 

Section 12.5 No Adjustments. The Conversion Rate shall not be adjusted for any transaction or event
other than as specified in this Article XII. 
 Section 12.6 Notice of Adjustments. Whenever the
Conversion Rate is adjusted, the Issuer shall promptly mail to Holders at the addresses appearing on the Registrar’s books a notice of the adjustment and file with the Trustee (and the Conversion Agent if not the Trustee) an Officers’
Certificate briefly stating the facts requiring the adjustment and the manner of computing it. The certificate shall be conclusive evidence of the correctness of such adjustment. Unless and until a Responsible Officer of the Trustee shall have
received such Conversion Rate, the Trustee(and the Conversion Agent if not the Trustee) shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has
knowledge is still in effect. 
 Section 12.7 Effect of Reclassifications, Consolidations, Mergers, Binding
Share Exchanges or Sales of Assets. 
 (a) In the event of: 

(1) any reclassification, recapitalization or change of the Common Stock (other than a change to par value, or from par value
to no par value, or changes resulting from a subdivision or combination); 

  
 117 

 (2) a consolidation, merger, binding share exchange or combination involving
the Issuer; or 
 (3) a sale or conveyance to another person or entity of all or substantially all of the Issuer’s
property or assets; 
 in which holders of Common Stock would be entitled to receive stock, other securities, other property, assets or cash
for their Common Stock (any such event, a “Merger Event”), the Applicable Percentage of each $1,000 in principal amount of the Notes will, from and after the effective time of such Merger Event, in lieu of being convertible into
Common Stock, be convertible into the same kind, type and proportions of consideration that a holder of a number of shares of Common Stock equal to the Conversion Rate in effect immediately prior to such Merger Event would have received in such
Merger Event (“Reference Property”) and, prior to or at the effective time of such Merger Event, the Issuer or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture providing
for such change in the right to convert the Notes. 
 (b) If the Merger Event causes the Common Stock to be converted into,
or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then (1) the Reference Property into which the Notes will be convertible shall be deemed to be the
weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election; and (2) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer
to the consideration referred to in clause (1) above attributable to one share of Common Stock. The Issuer shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable
after such determination is made. 
 (c) If, in the case of any Merger Event, the Reference Property includes shares of
stock, securities or other property or assets (other than cash and/or Cash Equivalents) of a Person other than the Issuer or the successor or purchasing entity, as the case may be, in such Merger Event, then such supplemental indenture shall also be
executed by such other Person and shall contain such additional provisions to protect the interests of the Holders as the Issuer shall reasonably consider necessary by reason of the foregoing. 

(d) The supplemental indenture referred to in this Section 12.7 shall, in the good faith judgment of the Issuer as
evidenced by an Officers’ Certificate, (1) provide for adjustments to the Conversion Rate and the Threshold Price that shall be as nearly equivalent as may be practicable to the adjustments to the Conversion Rate and the Threshold Price
provided for in this Indenture and for the delivery of cash by the Issuer in lieu of fractional securities or property that would otherwise be deliverable to Holders 

  
 118 

 
upon conversion as part of the Reference Property, with such amount of cash determined by the Issuer in a manner as nearly equivalent as may be practicable to that used by the Issuer to determine
the Daily VWAP of the Common Stock and (2) provide that after the Merger Event, the Mandatory Conversion Event (and related calculations) shall be determined with reference to the trading value of the Reference Property as determined in good
faith by the Issuer in a manner as nearly equivalent as may be practicable to that used by the Issuer to determine the Daily VWAP of the Common Stock. 

(e) The Issuer shall not become a party to any Merger Event unless its terms are consistent with this Section 12.7. 

Section 12.8 Notice of Certain Transactions. 

(a) In the event that: 

(1) the Issuer or any of its Subsidiaries takes any action that would require an adjustment in the Conversion Rate; 

(2) the Issuer takes any action that would require a supplemental indenture pursuant to Section 12.7; or 

(3) there is a dissolution or liquidation of the Issuer, 

the Issuer shall promptly mail to the Holders at the addresses appearing on the Registrar’s books and the Trustee a written notice stating
the proposed record date and effective date of the transaction referred to in clause (1), (2) or (3) above. 

Section 12.9 Issuer to Reserve, Provide and List Common Stock. 

(a) The Issuer shall at all times reserve out of its authorized but unissued and unreserved shares of Common Stock or shares of
Common Stock held in its treasury a sufficient number of shares of Common Stock to permit the conversion, in accordance with the terms of this Indenture, of the Applicable Percentage of all of the Notes outstanding (assuming that such Notes are
converted after the last Interest Payment Date prior to the scheduled maturity date of the Notes). 
 (b) All shares of
Common Stock issued upon conversion of the Notes shall be duly and validly issued, fully paid and non-assessable and shall be free of preemptive or similar rights and free of any tax, lien or adverse claim
(except to the extent of any lien or adverse claim created by the action or inaction of the Holder of such Notes or the Person to whom such shares of Common Stock will be delivered). 

(c) The Issuer shall comply with all securities laws regulating the offer and delivery of shares of Common Stock upon
conversion of Notes and, if at any time the Common Stock shall be listed on any national securities exchange or automated quotation system, the Issuer shall list and keep listed, so long as the Common Stock shall be so listed on such exchange or
automated quotation system, any Common Stock issuable upon conversion of the Applicable Percentage of the Notes. 

  
 119 

 Section 12.10 Responsibility of the Trustee. 

(a) The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder to
determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) 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 Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the exchange of any Note; 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 Issuer to issue, transfer or deliver any Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the
purpose of exchange or to comply with any of the duties, responsibilities or covenants of the Issuer contained in this Article. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any
responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 12.7 relating either to the kind or amount of Common Stock or securities or property (including cash)
receivable by Holders upon the exchange of their Notes after any event referred to in such Section 12.7 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.1, may accept (without any
independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Issuer shall be obligated to file with the Trustee prior to the execution
of any such supplemental indenture) with respect thereto. Neither the Trustee, nor the Conversion Agent shall have any obligation to independently determine or verify if any Mandatory Conversion Event or any other event has occurred or notify the
Holders of any such event. The Parties hereto agree that all notices to the Trustee or the Conversion Agent under the Article XII shall be in writing. 

Article XIII 
 COLLATERAL
AND SECURITY 
 Section 13.1 Security Interest 

(a) The due and punctual payment of the Note Obligations and the Obligations of the Guarantors under the Note Guarantees, when
and as the same shall be due and payable, whether on an interest payment date, at maturity, by acceleration, repurchase, redemption or otherwise, and interest on the overdue principal of, premium (including the Applicable Premium and Redemption
Premium), if any, and interest (including interest and other Obligations accruing during the pendency of a bankruptcy, insolvency, receivership or other similar proceeding regardless of whether allowed or allowable in such proceeding), on the Notes,
the Note Guarantees and the performance and payment of all other obligations of the Issuer and the Guarantors to the Holders or 

  
 120 

 
the Trustee and/or the Notes Collateral Agent under the Note Documents, according to the terms hereunder or thereunder (collectively, the “Secured Obligations”), are secured as
provided in the Security Documents. The Issuer and each Guarantor consents and agrees to be bound by the terms of the Security Documents to which it is a party, as the same may be in effect from time to time, and agrees to perform its obligations
thereunder in accordance therewith. The Issuer and each Guarantor hereby agrees that, subject to the Intercreditor Agreement, the Notes Collateral Agent shall hold the Collateral on behalf of and for the benefit of all of the Holders. 

(b) Each Holder, by its acceptance of the Notes and of the Note Guarantees, consents and agrees to the terms of the
Intercreditor Agreement and the Security Documents (including, without limitation, the provisions providing for foreclosure and release of Collateral and amendments to the Security Documents) as the same may be in effect or may be amended from time
to time in accordance with their terms, and authorizes and appoints U.S. Bank National Association as the Trustee and as the Notes Collateral Agent. The Trustee hereby authorizes and appoints U.S. Bank National Association as Notes Collateral Agent,
and each Holder and the Trustee direct the Notes Collateral Agent to enter into the Security Documents and to perform its obligations and exercise its rights thereunder in accordance therewith, subject to the terms and conditions thereof. The
Trustee, the Notes Collateral Agent and each Holder, by accepting the Notes and the Note Guarantees of the Guarantors, acknowledges that, as more fully set forth in the Security Documents, the Collateral as now or hereafter constituted shall be
held, subject to the Intercreditor Agreement, for the benefit of all the Holders, the Notes Collateral Agent and the Trustee, and the Lien of this Indenture and the Security Documents is subject to and qualified and limited in all respects by the
Intercreditor Agreement, the Security Documents and actions that may be taken thereunder. 
 Section 13.2 Post-Issue Date
Collateral Requirements. 
 (a) Within 90 days of the Issue Date, the Issuer shall, or shall cause the applicable
Guarantor to, execute and deliver to the Notes Collateral Agent, (1) deeds of trust, trust deeds, deeds to secure debt, or mortgages, as applicable, solely with respect to Material Real Property owned by such entity sufficient, upon recordation
in the proper recorder’s office or appropriate public records (and payment of any taxes or fees in connection therewith) to grant a first priority Lien to the Notes Collateral Agent, for the benefit of the Holders, on such Material Real
Property, and upon such filing or recordation shall also deliver one or more Opinions of Counsel with respect to the execution, delivery and enforceability of the applicable documentation referred to in this clause (1) and (2) with respect to
any Material Real Property described in clause (1), (A) deliver to the Notes Collateral Agent a completed “Life-of-Loan” Federal Emergency Management Agency
Standard Flood Hazard Determination, together with a notice executed by the Issuer or such Guarantor, as applicable, about special flood hazard area status, if applicable, in respect of such Material Real Property and (B) if such Material Real
Property is located in a special flood hazard area, evidence of flood insurance, and any title reports, surveys, and environmental assessment reports regarding such Material Real Property as may be in the possession of such entity. 

  
 121 

 (b) Within 60 days of the Issue Date, the Issuer shall, or shall cause the
applicable Guarantor to, pledge pursuant to the terms of the Security Agreement (and execute an addendum thereto as required thereunder), the Equity Interests of each CFC or FSHCO directly owned by the Issuer or such Guarantor that has not already
been pledged to the Notes Collateral Agent (or its agent or bailee) (other than to the extent such Equity Interests constitute Excluded Property (as defined in the Security Agreement)), together with certificates or instruments, if any, representing
or evidencing Equity Interests of each such Subsidiary, in each case accompanied by undated stock powers (or other instruments of transfer) endorsed in blank to be delivered to the Notes Collateral Agent. 

(c) Any Security Documents entered into after the Issue Date shall be substantially in the form of the corresponding Security
Document entered on the Issue Date, and no such Security Document shall be materially more burdensome upon the Issuer or its Subsidiaries than the Security Documents executed and delivered by the Issuer and the Guarantors in connection with the
Issue Date, unless such Guarantor is willing to agree or has agreed to such similar terms in the corresponding security document for the Credit Agreement Within 45 days of the Issue Date, the Issuer shall provide the Notes Collateral Agent with
evidence that the Trustee and Notes Collateral Agent are named (through an endorsement or amendment to the applicable policy) as an additional insured on all liability insurance policies of the Issuer and the Guarantors for which the ABL Facility
Collateral Agent is named as an additional insured. If at any time there is no Credit Agreement, the Issuer and the Guarantors shall continue to cause the Trustee and Notes Collateral Agent to be so named as contemplated in the preceding sentence.

 Section 13.3 Further Assurances; Liens on Additional Property. 

(a) Each of the Issuer and the Guarantors shall do or cause to be done all acts and things that may be required, or that the
Notes Collateral Agent from time to time may reasonably request, to assure and confirm that the Notes Collateral Agent holds, for the benefit of the Holders, duly created, enforceable and perfected Liens upon the Collateral (including any property
or assets constituting Collateral that are acquired or otherwise become, or are required by this Section 13.3 or any Security Document to become, Collateral after the Issue Date), in each case, as contemplated by, and, to the extent required to
be perfected, perfected and enforceable Liens, with the Lien priority required under, the Indenture and the Security Documents, and in connection with any merger, consolidation or sale of assets of any Guarantor, the property and assets of the
Person which is consolidated or merged with or into such Guarantor, to the extent that they are property or assets of the types which would constitute Collateral under the Security Documents, shall be treated as after-acquired property and such
Guarantor shall take such action as may be reasonably necessary to cause such property and assets to be made subject to the Note Liens, in the manner and to the extent required by this Section 13.3 or any Security Document. 

  
 122 

 (b) The Issuer and each Guarantor shall promptly execute, acknowledge,
deliver and file such financing statements, continuation statements, fixture filings, Security Documents, Opinions of Counsel, instruments, certificates, notices and other documents, and take such other actions as shall be required or reasonably
necessary, or that the Notes Collateral Agent may reasonably request or at any time and from time to time, to create, perfect, continue perfecting, further perfect, protect, assure or enforce the Liens and benefits intended to be conferred, in each
case as contemplated by the Note Documents for the benefit of the holders of Note Obligations; provided, that no such Security Document, instrument or other document shall contain provisions that are materially more burdensome upon the Issuer or its
Subsidiaries than the Security Documents, instruments and documents executed and delivered (or required to be executed and delivered after the Issue Date pursuant to Section 13.2) by the Issuer and the Guarantors in connection with the issuance
of the Notes on the Issue Date, so long as the corresponding Security Document for the Credit Agreement is similarly not materially more burdensome upon the Issuer or its Subsidiaries. Further, to the extent that any Lien on any Collateral is
perfected by the possession or control of such Collateral or of any account in which such Collateral is held, and if such Collateral or any such account is in fact in the possession or under the control of the ABL Facility Collateral Agent, or of
agents or bailees of the ABL Facility Collateral Agent, any requirement for perfection or control of such Collateral under this Indenture or the Security Documents shall be deemed to have been satisfied. 

(c) In addition, from and after the Issue Date, if the Issuer forms or acquires any new direct or indirect Domestic Subsidiary
that becomes, or is required to become, a Guarantor as set forth under Section 4.15, the Issuer shall, at the Issuer’s expense (1) within 45 days of such acquisition or formation, (A) cause such new Domestic Subsidiary to provide
to the Notes Collateral Agent a joinder to the Security Agreement, in each case, together with such other Security Documents or supplements to the Security Documents, as well as appropriate financing statements, sufficient to grant the Notes
Collateral Agent, for the benefit of the Holders, a first priority Lien on Notes Priority Collateral (other than Material Real Property) and a second priority Lien on ABL Priority Collateral, in each case, subject to Permitted Liens, in and to the
assets of such newly formed or acquired Domestic Subsidiary and (B) provide to the Notes Collateral Agent an Opinion of Counsel with respect to the execution and delivery of the applicable documentation referred to above and (2) within 90
days after such formation or acquisition, (A) cause such Domestic Subsidiary to duly execute and deliver to the Notes Collateral Agent deeds of trust, trust deeds, deeds to secure debt, or mortgages, as applicable, solely with respect to
Material Real Property owned by such new Domestic Subsidiary sufficient, upon recordation in the proper recorders’ offices or appropriate public records (and payment of any taxes or fees in connection therewith), to grant a first priority Lien
to the Notes Collateral Agent, for the benefit of the Holders, on such Material Real Property, and upon such filing or recordation shall also deliver one or more Opinions of Counsel with respect to the execution, delivery and enforceability of the
applicable documentation referred to in this clause (A) and (B) with respect to any Material Real Property described in clause (A), (i) deliver to the Notes Collateral Agent a completed “Life-of-Loan” Federal Emergency Management Agency Standard Flood Hazard determination, together with a notice executed by such Guarantor about special flood hazard area status, if applicable, in
respect of such Material Real Property and (ii) if such Material Real Property is located in a special flood hazard area, evidence of flood insurance, and any title reports, surveys, and environmental assessment reports regarding such Material
Real Property as may be in the possession of such entity. 

  
 123 

 (d) In addition, from and after the Issue Date, upon the acquisition of any

 (Back of 9.000% Convertible Senior Secured Note) 

9.000% Senior Secured Notes due 2025 

Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 

(1) Interest. Forum Energy Technologies, Inc., a Delaware corporation, and any successor thereto (the “Issuer”)
promises to pay interest on the unpaid principal amount of this 9.000% Senior Secured Note due 2025 (a “Note”) at a fixed rate of 9.000% per annum. The Issuer will pay interest in semiannually in arrears on April 1 and
October 1, commencing on October 1, 2020 (each an “Interest Payment Date”) or if any such day is not a Business Day, on the next succeeding Business Day with the same force and effect as if made on such Interest Payment
Date, and no additional interest shall accrue solely as a result of such delayed payment. Interest on the Notes shall accrue from the most recent date to which interest has been paid, or, if no interest has been paid, from and including the date of
issuance. The Issuer shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium (including the Applicable Premium and Redemption Premium), if any, at the rate equal to the then
applicable interest rate on the Notes to the extent lawful; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period), at
the same rate to the extent lawful. Interest shall be computed on the basis of a 360-day year comprised of twelve 30-day months. 

Interest will be payable, at the election of the Issuer, (1) entirely in cash consisting of U.S. Dollars (“Cash
Interest”) or (2) by paying 6.250% per annum as Cash Interest and 2.750% per annum by increasing the principal amount of the outstanding Notes or by issuing PIK Interest Notes (having a principal amount equal to the amount of interest
so paid). 
 (2) Method of Payment. The Issuer will pay interest on the Notes (except defaulted interest) on the applicable Interest
Payment Date to the Persons who are registered Holders at the close of business on the March 15 and September 15 preceding the Interest Payment Date (whether or not a Business Day), even if such Notes are cancelled after such record date
and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Issuer will make payments in respect of Global Notes by wire transfer of immediately available funds to the
accounts specified by DTC or its Nominee. If a Holder of at least $1.0 million principal amount of certificated Notes has given written wire transfer instructions to the Issuer at least 10 Business Days prior to the applicable Interest Payment
Date, the Issuer will make all payments of principal, premium (including the Applicable Premium and Redemption Premium) and interest on such Holder’s Notes by wire transfer of immediately available funds to the account in New York specified in
those instructions. Otherwise, payments on the Notes will be made at the office or agency of the Trustee or Paying Agent in the City and State of New York unless the Issuer elects to make interest payments by check mailed to the Holders at their
addresses set forth in the register of Holders. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 

  
 A-3 

 Any payments of principal of this Note prior to Stated Maturity shall be binding upon all
future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not noted hereon. The final principal amount due and payable at the maturity of this Note shall be
payable only upon presentation and surrender of this Note at an office of the Trustee or the Trustee’s agent appointed for such purposes. Payments in respect of Global Notes will be made by wire transfer of immediately available funds to the
Depositary. 
 PIK Interest will be considered paid on the date due if on such date the Trustee has received (a) a written order,
pursuant to Section 2.2 of the Indenture, from the Issuer signed by an Officer of the Issuer to increase the balance of any Global Note to reflect such PIK Interest or (b) PIK Interest Notes duly executed by the Issuer together with a
written order, pursuant to Section 2.2 of the Indenture, of the Issuer signed by an Officer of the Issuer requesting the authentication of such PIK Interest Notes by the Trustee. In connection with the payment of PIK Interest in respect of the
Notes, the Issuer will, without the consent of Holders (and without regard to any restrictions or limitations set forth under Section 4.9 of the Indenture), either increase the outstanding principal amount of the Global Notes or issue PIK
Interest Notes under the Indenture. 
 (3) Paying Agent and Registrar. Initially, U.S. Bank National Association shall act as Paying
Agent and Registrar. The Issuer may change any Paying Agent or Registrar without notice to any Holder, and the Issuer and/or any Subsidiaries may act as Paying Agent or Registrar. 

(4) Indenture. The Issuer issued the Notes under an Indenture, dated as of August 4, 2020 (the “Indenture”), among the
Issuer, the Guarantors thereto and the Trustee. The terms of the Notes include those stated in the Indenture and those made a part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb)
(the “TIA”). To the extent the provisions of this Note are inconsistent with the provisions of the Indenture, the Indenture shall govern. The Notes are subject to all such terms, and Holders are referred to the Indenture and the TIA for a
statement of such terms. The Initial Notes issued on the Issue Date were initially issued in an aggregate principal amount of $315,489,000. The Indenture permits the issuance of Additional Notes subject to compliance with certain conditions. 

The payment of principal, premium (including the Applicable Premium and Redemption Premium) and interest on the Notes and all other amounts
under the Indenture is unconditionally guaranteed, jointly and severally, on a senior unsecured basis by the Guarantors and secured by Collateral. 

(5) Optional Redemption.

part, at any time or from time to time prior to August 4, 2022 at the option of the Issuer, at a redemption price equal to 100.0% of the principal amount of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest

 (8) Notice of Redemption.

the Indenture) to each Holder whose Notes are to be redeemed in accordance with Section 11.2 of the Indenture. Notes in denominations larger than $1.00 may be redeemed in part so long as no partial redemption results in a Note having a
principal amount of less than $1.00. 
 (9) Conversion. The Applicable Percentage of the Notes shall be convertible into shares of
Common Stock in accordance with, and upon the conditions set forth in, Article XII of the Indenture. To convert a Note at its option in connection with any redemption pursuant to Section 3.7 of the Indenture, a Holder must follow the procedures
that will be set forth in the Optional Conversion Notice delivered by the Issuer pursuant to Section 12.1 of the Indenture. Upon conversion of any Notes pursuant to an Optional Conversion or Mandatory Conversion, the Holder thereof shall be

Issuer, or the Holders of at least 25.0% in aggregate principal amount of the Notes then outstanding by written notice to the Issuer and the Trustee, may declare all amounts owing under the Notes to be due and payable (including the Applicable
