(a) The Notes shall be signed in the name and on behalf of the Company by the manual or facsimile signature of its Chief
Executive Officer, President, Chief Financial Officer, Treasurer, Secretary or any of its Executive or Senior Vice Presidents. 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; and any Note may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Note, shall be the Officers of the Company, although at the date of the execution of this Indenture any such
person was not such an Officer.

relating to the Notes issued under this Indenture are set forth in Appendix A, which is hereby incorporated in and expressly made a part of this Indenture. 

Section 2.04. Exchange and Registration of Transfer of Notes; Restrictions on Transfer; Depositary.

(c) At the option of the Holder, Notes may be exchanged for other Notes of any authorized denomination or denominations of a
like aggregate principal amount upon surrender of the Notes to be exchanged to the Note Registrar. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the replacement Notes

exchange, repurchase or conversion shall (if so required by the Company, the Trustee, the Note Registrar or any co-Note Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of
transfer in form reasonably satisfactory to the Company and the Trustee as Note Registrar and duly executed, by the Holder thereof or its attorney-in-fact duly
authorized in writing. 
 (e) No service charge shall be imposed by the Company, the Trustee, the Note Registrar, any co-Note Registrar or the Paying Agent for any exchange or registration of transfer of Notes, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer
tax required in connection therewith as a result of the name of the Holder of new Notes issued upon such exchange or registration of transfer being different from the name of the Holder of the old Notes surrendered for exchange or registration of
transfer. 
 (f) None of the Company, the Trustee, the Note Registrar or any co-Note
Registrar shall be required to exchange or register a transfer of (i) any Notes, or a portion of any Note, surrendered for conversion in accordance with Article 17, (ii) any Notes, or a portion of any Note, surrendered for repurchase
(and not withdrawn) in accordance with Article 18 or (iii) any Notes, or a portion of any Note, selected for redemption in accordance with Article 19. 

(g) All Notes issued upon any registration of transfer or exchange of Notes in accordance with this Indenture shall be the
valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or exchange. 

The Trustee will have no obligation or duty to monitor, determine or inquire as to compliance with any transfer restrictions
imposed under this Indenture or applicable law with respect to any Note (including any transfers between or among Depositary participants, members or beneficial owners in any Global Note), other than to require the delivery of such certificates or
other documentation or evidence as expressly required by this Indenture and to examine the same to determine substantial compliance as to form with the express requirements of this Indenture. 

  
 48 

 (i) The Trustee shall have no responsibility or obligation to any beneficial
owner of a Global Note, 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 participant or member thereof, with respect to any ownership interest
in the Notes or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depositary) of any notice or the payment of any amount, under or with respect to such Notes. All notices and communications to
be given to the Holders and all payments to be made to the Holders under the Notes shall be given or made only to the registered Holders (which shall be the Depositary or its nominee in the case of a Global Note). The rights of beneficial owners in
any Global Note shall be exercised only through the Depositary subject to the applicable rules and procedures of the Depositary. The Trustee 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. 
 Section 2.05. Mutilated, Destroyed, Lost or Stolen Notes. 

(a) In case any Note shall become mutilated or be destroyed, lost or stolen, and the Trustee and the Registrar receive evidence
to its satisfaction of the ownership and loss, destruction or theft of such Note, the Company shall issue and the Trustee, upon receipt of a Company Order, shall authenticate a replacement Note if the Trustee’s requirements are otherwise met.
An indemnity bond must be provided by the Holder that is sufficient in the judgment of the Trustee to protect the Trustee and in the judgment of the Company to protect the Company, the Trustee, and any Agent from any loss that any of them may suffer
if a Note is replaced. The Holder shall also furnish to the Company, the Trustee and any Agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereto. No service charge shall be imposed on the
Holder by the Company, the Trustee, the Note Registrar, or any Agent upon the issuance of any substitute Note, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in
connection therewith as a result of the name of the Holder of the new substitute Note being different from the name of the Holder of the old Note that became mutilated or was destroyed, lost or stolen. Every replacement Note is a contractual
obligation of the Company and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder. 

(b) In case any Note that has matured or is about to mature or has been surrendered for required repurchase or is about to be
converted shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender
thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and any Agent from any loss that any of them may suffer if a Note is paid or converted
together with evidence satisfactory to the Company, the Trustee and any Agent of the destruction, loss or theft of such Note and of the ownership thereof. 

  
 49 

 (c) Every substitute Note issued pursuant to the provisions of this
Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any
time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder.

as not outstanding as follows: 
 (i) Notes theretofore canceled or accepted by the Trustee for cancellation pursuant to
Section 2.08; 
 (ii) Notes, or portions thereof that have become due and payable and in respect of

Paying Agent); 
 (iii) Notes that have been paid pursuant to Section 4.01; 

(iv) Notes in lieu of which, or in substitution for which, other Notes shall have been authenticated and delivered pursuant to
the terms of Section 2.05 unless proof satisfactory to the Trustee is presented that any such Notes are held by protected purchasers in due course; 

(v) Notes converted pursuant to Article 17 and required to be cancelled pursuant to
Section 2.08;

 Section 2.07. Temporary Notes. Until definitive Notes are ready for
delivery, the Company may prepare and the Trustee, upon receipt of a Company Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Company considers
appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes. Holders and beneficial
holders, as the case may be, of temporary Notes shall be entitled to all of the benefits accorded to Holders, or beneficial holders, respectively, of Notes under this Indenture.

redemption, registration of transfer or exchange or conversion, if surrendered to any Person other than the Trustee (including any of the Company’s agents, Subsidiaries or Affiliates), to be surrendered to the Trustee for cancellation. All
Notes delivered to the Trustee shall be accepted by and canceled promptly by it, and no Notes shall be authenticated in exchange thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of canceled
Notes in accordance with its customary procedures.

Payments. 
 (a) Each Note shall bear interest from the date specified on the face of such Note. 

(b) Accrued interest on the Notes shall be computed on the basis of a 360-day year
composed of twelve 30-day months and, for partial months, on the basis of the number of days actually elapsed in a 30-day month. The Person in whose name any Note (or
its Predecessor Note) is registered on the Note Register at the close of business on any Regular Record Date with respect to any Interest Payment Date shall be entitled to receive the interest payable on such Interest Payment Date. The principal
amount of any Note (x) in the case of any Physical Note, shall be payable through the Paying Agent at the office or agency of the Company maintained by the Company for such purposes in the contiguous United States of America, which shall
initially be the Corporate Trust Office and (y) in the case of any Global Note, shall be payable through the Paying Agent by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Company shall pay

relevant Regular Record Date, by wire transfer in immediately available funds to that Holder’s U.S. dollar account within the United States, which application shall remain in effect until the Holder notifies, in writing, the Paying Agent to the
contrary or (ii) on any Global Note by wire transfer of immediately available funds to the account of the Depositary or its nominee. 

  
 51 

 (c) Any Defaulted Amounts shall accrue interest per annum at the rate borne
by the Notes plus one percent, subject to the enforceability thereof under applicable law, from, and including, such relevant payment date, and such Defaulted Amounts together with such interest thereon shall be paid by the Company, at its election
in each case, as provided in clause (i) or (ii) below: 
 (i) The Company may elect to make payment of any Defaulted
Amounts to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on a special record date for the payment of such Defaulted Amounts, which shall be fixed in the following manner. The
Company shall notify the Trustee in writing of the amount of the Defaulted Amounts proposed to be paid on each Note and the date of the proposed payment (which shall be not less than 20 days after the receipt by the Trustee of such notice, unless
the Trustee shall consent to an earlier date), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts on or prior to the date of the proposed
payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Amounts as in this clause provided. Thereupon the Company shall fix a special record date for the payment of such Defaulted Amounts
which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment, and not less than five days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the
Trustee of such special record date and the Trustee, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Amounts and the special record date therefor to be delivered to each Holder at its
address as it appears in the Note Register, not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Amounts and the special record date therefor having been so delivered, such Defaulted Amounts shall
be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such special record date and shall no longer be payable pursuant to the following clause (ii) of this
Section 2.09(c). 
 (ii) The Company may make payment of any Defaulted Amounts in any other lawful
manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated quotation
system, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be practicable and in accordance with terms hereof. 

(iii) The Trustee will have no duty whatsoever to determine whether any Defaulted Amounts are payable or the amount thereof.

 Section 2.10. CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if then generally in
use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either
as printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company and each Guarantor (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law,
and covenant 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.

constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, if at any time the Company and the Guarantors are not required to file the reports required by the preceding paragraphs with the SEC, they
will furnish to the Trustee and the Collateral Trustee, the Holders and to securities analysts and prospective investors in the Notes, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act
to facilitate the resale of such Notes or shares of Common Stock pursuant to Rule 144A. The Company shall take such further action as any Holder or beneficial owner of such Notes or such Common Stock may reasonably request to the extent from time to
time required to enable such Holder or beneficial owner to sell such Notes or shares of Common Stock in accordance with Rule 144A, as such rule may be amended from time to time. The Company will be deemed to have provided such information to the
Holders of the Notes, the beneficial owners of the Notes, securities analysts and prospective holders of the Notes if it has filed reports containing such information with the SEC via the EDGAR filing system and such reports are publicly available.

 (c) Delivery of the reports and documents described in subsections (a)-(b) above to the Trustee and/or the Collateral
Trustee is for informational purposes only, and the Trustee’s and/or Collateral Trustee’s receipt of such shall not constitute actual or constructive notice of any information contained therein or determinable from information contained
therein, including the Company’s or any other Person’s compliance with any of its covenants hereunder (as to which the Trustee and/or Collateral Trustee is entitled to conclusively rely on an Officers’ Certificate). The Trustee and
the Collateral Trustee shall have no liability or responsibility for the filing, timeliness or content of any report delivered hereunder. It is further understood that neither the Trustee nor the Collateral Trustee shall have any obligation
whatsoever to monitor or confirm, on a continuing basis or otherwise, the Company’s or any other Person’s compliance with this Section 4.05 or to determine whether or not such reports or documents or reports have
been filed with the SEC or otherwise.

Indenture during such fiscal year and, if so, specifying each such failure, the nature thereof and advise as to steps to cure such condition; and 

  
 57 

 (ii) within five (5) Business Days of an Officer obtaining knowledge
thereof or the occurrence thereof, of any event or condition which constitutes an Event of Default or Default, an Officers’ Certificate setting forth the details of such Event of Default or Default, its status and the action that the Company is
taking or proposing to take in respect thereof. 
 (b) In addition, the Company agrees that no Company Indenture Party or
Domestic Subsidiary of the Company will have a fiscal year different from that of the Company. The Company agrees to maintain a system of accounting that enables the Company to produce financial statements in accordance with GAAP. Each Company
Indenture Party shall also (a) keep a reporting system that shows all additions, sales, claims, returns, and allowances with respect to the sales of such Company Indenture Party and its Subsidiaries, and (b) maintain its billing
systems/practices substantially as in effect as of the date hereof and shall only make material modifications following at least 30 days’ prior notice to the Collateral Trustee (and Collateral Trustee shall promptly deliver the same to each

Section 4.08. Existence. Except as otherwise permitted under Section 5.03 or
Section 5.04, each Company Indenture Party and each Domestic Subsidiary shall at all times maintain and preserve in full force and effect (a) its existence (including being in good standing in its jurisdiction of
organization) and (b) all rights and franchises, contracts, licenses and permits material to its business; provided, however, that no Company Indenture Party nor any of its Subsidiaries shall be required to preserve any such right or franchise,
licenses, contracts, or permits if such Person’s Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of such Person, and that the loss thereof is not disadvantageous in any
material respect to such Person or to the Collateral Trustee or the Holders; provided, that the Company delivers at least ten (10) days prior written notice to the Trustee and/or Collateral Trustee of the election of such Company Indenture
Party or such Subsidiary not to preserve any such right or franchise, contract, license or permit. 
 Section 4.09. Maintenance of
Properties. (a) Maintain and preserve all of its assets that are necessary or useful in the proper conduct of its business in good working order and condition, (ordinary wear, tear and casualty excepted) other than (x) Permitted
Dispositions and (y) where the failure to so maintain and preserve such assets could not reasonably be expected to result in a Material Adverse Change, and (b) comply with the material provisions of all material leases and licenses to
which it is a party as lessee or licensee, so as to prevent the loss or forfeiture thereof, unless such provisions are the subject of a Permitted Protest. 

  
 58

(a) Timely file all federal and state income tax returns and other material tax returns required to be filed or otherwise
supplied to a Governmental Authority with respect to taxes, and pay and discharge (y) all material Taxes imposed, levied, or assessed against any Company Indenture Party or its Subsidiaries, or any of their respective assets or in respect of
any of its income, businesses, or franchises to be paid in full, before delinquency or the expiration of any extension period, and (z) all material claims (including claims for labor, services, materials and supplies) for sums that have become
due and payable and that by law have or may become a Lien upon any of their properties or assets which, in each case, could be a liability of or be imposed on Company or any of its Subsidiaries); provided no such Tax, claim or obligation need to be
paid if it could not reasonably be expected to result in a Material Adverse Change or the validity of such Tax, claim or obligation is the subject of a Permitted Protest and so long as, in the case of such Tax, claim or obligation that has or may
become a Lien against any of the Collateral, such Permitted Protest conclusively operates to stay the sale of any portion of the Collateral to satisfy such assessment or Tax; and 

(b) Make timely payment or deposit of all tax payments and withholding taxes required of it and them by applicable laws,
including those laws concerning F.I.C.A., F.U.T.A., state disability, and local, state, and federal income taxes, and will, upon request of Collateral Trustee (at the direction of Required Holders), furnish Collateral Trustee with proof reasonably
satisfactory to the Required Holders indicating that such Company Indenture Party and its Subsidiaries have made such payments or deposits. 

Section 4.11. Insurance. At the Company Indenture Parties’ expense, each Company Indenture Party and each Domestic
Subsidiary shall maintain insurance with respect to the assets of each Company Indenture Party and each of its Subsidiaries (other than Excluded Subsidiaries) wherever located, covering liabilities, losses or damages as are customarily insured
against by other Persons engaged in the same or similar businesses. All such policies of insurance shall be with financially sound and reputable insurance companies and in such amounts and scope as is carried generally in accordance with
sound business practice by companies in similar businesses similarly situated and located. All property insurance policies covering the Collateral are to be made payable to the Collateral Trustee for the benefit of the Secured Parties (subject to
the Intercreditor Agreement), as its interests may appear, in case of loss, pursuant to a lender loss payable endorsement and are to contain such other provisions as the Required Holders may reasonably require to fully protect the Secured
Parties’ interest in the Collateral and to any payments to be made under such policies. Such evidence of property and general liability insurance shall be delivered to the Collateral Trustee as provided by
Section 4.17(a), with the lender loss payable endorsements (but only in respect of Collateral) and additional insured endorsements (with respect to general liability coverage) in favor of the Collateral Trustee (subject to
the Intercreditor Agreement) and shall provide for not less than 30 days’ (10 days in the case of non-payment) prior written notice to the Collateral Trustee of the exercise of any right of cancellation.
If the Company fails to maintain such insurance, the Collateral Trustee may, but shall not be obligated to, arrange for such insurance, but at the Company Indenture Parties’ expense and without any responsibility on the Collateral
Trustee’s part for obtaining the insurance, the solvency of the insurance companies, the adequacy of the coverage, or the collection of claims. Except as otherwise provided in the Security Documents, the Company shall give the Collateral
Trustee prompt notice of any loss exceeding $500,000 covered by its casualty or business interruption insurance. Upon the occurrence and during the continuance of an Event of Default, 

  
 59 

 
(subject to the Intercreditor Agreement) the Collateral Trustee (at the direction of Required Holders) shall have the sole right to file claims under any property and general liability insurance
policies in respect of the Collateral, to receive and give acquittance for any payments that may be payable thereunder, and to execute any and all endorsements, receipts, releases, assignments, reassignments or other documents that may be necessary
to effect the collection, compromise or settlement of any claims under any such insurance policies.

any Governmental Authority, other than laws, rules, regulations, and orders the non-compliance with which, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse
Change, subject to Company Indenture Parties’ right to engage in a Permitted Protest; provided, however, that this Section 4.14 shall not apply to laws related to Taxes, which are the subject of
Section 4.10. 
 Section 4.15. Environmental. 

(a) Keep any property either owned or operated by the Company or any other Company Indenture Party free of any Environmental
Liens or post bonds or other financial assurances in an amount sufficient to satisfy the obligations or liability evidenced by such Environmental Liens, subject to Company Indenture Parties’ right to engage in a Permitted Protest so long as, in
the case of an Environmental Lien that has become a Lien against any of the Collateral, (i) such contest proceedings conclusively operate to stay the sale of any portion of the Collateral to satisfy such Environmental Lien(s), and (ii) any
such other Lien is at all times subordinate to the Collateral Trustee’s Liens; 
 (b) Comply, in all material respects,
with Environmental Laws and provide to the Collateral Trustee documentation of such compliance which the Collateral Trustee reasonably requests, subject to Company Indenture Parties’ right to engage in a Permitted Protest;

requests such notices) of any material release of which the Company or any other Company Indenture Party has knowledge of a Hazardous Material from or onto property owned or operated by Company or any other Company Indenture Party and take any
Remedial Actions required to abate said release or otherwise to come into compliance, in all material respects, with applicable Environmental Law; and 

(d) Promptly, but in any event within 5 Business Days of its receipt thereof, provide the Collateral Trustee with written

the foregoing provision will not cure or remedy the effect of the prior untrue statement of a material fact or omission of any material fact nor shall any such notification have the effect of amending or modifying this Indenture or any of the
Schedules hereto;

 (b) Delivery of the
information described in subsection (a) above, and in Section 4.19 below, to the Trustee and/or the Collateral Trustee is for informational purposes only, and the Trustee’s and/or Collateral Trustee’s receipt of such shall not

 ARTICLE 5 

Negative Covenants 
 So long as
any of the Notes remain outstanding, the Company and each Company Indenture Party covenants and agrees that, neither the Company nor any other Company Indenture Party will do, nor will the Company or any other Company Indenture Party permit any of
their Subsidiaries (other than the Excluded Subsidiaries unless expressly specified otherwise below) to do any of the following: 

Section 5.01. Indebtedness. 

(a) create, incur, assume, suffer to exist, guarantee, or otherwise become or remain, directly or indirectly, liable with
respect to any Indebtedness, except for Permitted Indebtedness. 
 (b) incur any Permitted Indebtedness that is contractually
subordinated in right of payment to any other Indebtedness of a Company Indenture Party (other than the ABL Loan Obligations and Term Loan Obligations) unless such Indebtedness is also contractually subordinated in right of payment to the
Obligations on substantially identical terms; provided, however, that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Company solely by virtue of being unsecured or by virtue of
being secured on a junior Lien basis. 
 For purposes of determining compliance with Section 5.01, in the event
that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Indebtedness, or is entitled to be incurred pursuant to Section 5.01(a), the Company will be permitted to classify and
divide such item of Indebtedness on the date of its incurrence, and later reclassify and redivide all or a portion of such item of Indebtedness among any one or more of such clauses and/or Section 5.01(a), in any manner
that complies with Section 5.01. Indebtedness under this Indenture will initially be deemed to have been incurred on such date in reliance on the exception provided by clause (a) of the definition of Permitted
Indebtedness. For purposes of determining compliance with any U.S. dollar denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be utilized,
calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred. Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that any Company Indenture Party may incur
pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values. In determining the amount of Indebtedness outstanding, the outstanding amount of any particular Indebtedness of any
Person shall be counted only once. 
 Section 5.02. Liens. Create, incur, assume, or suffer to exist, directly or
indirectly, any (a) Lien on or with respect to any of its assets, of any kind, whether now owned or hereafter acquired, or any income or profits therefrom, except for Permitted Liens; (b) Lien of any subcontractor of any Company Indenture
Party on the assets of any customer of any Company Indenture Party, unless, and to the extent, such subcontractor Lien is discharged, satisfied, vacated, bonded, or stayed within five (5) Business Days thereof; (c) Lien on or with respect
to any assets of any Company Indenture Party or any of its Subsidiaries (other than Excluded Subsidiaries), of any kind, whether now owned or hereafter acquired, or any income or profits therefrom, in each case, for the benefit of any Excluded
Subsidiary or (d) Lien on or with respect to any Excluded Subsidiary’s assets, of any kind, whether now owned or hereafter acquired, or any income or profits therefrom, to secure Indebtedness for borrowed money other than the Closing Date
Acquisition Obligations and the Liens described in the clause (f) of “Permitted Liens” as defined in the Closing Date Loan Agreement as in effect on the date hereof. 

  
 63 

 Section 5.03. Restrictions on Fundamental Changes.

merger between Company Indenture Parties; provided, that the Company must be the surviving entity of any such merger to which it is a party, (ii) any merger between any Company Indenture Party’s Subsidiaries that are not Company
Indenture Parties; (iii) any merger contemplated in accordance with Section 4.19 hereof and (iv) any reorganization, recapitalization or reclassification constituting a Merger Event to which
Section 17.07 applies; 
 (b) liquidate, wind up, or dissolve itself (or suffer any liquidation or
dissolution), except for (i) the liquidation or dissolution of non-operating Subsidiaries of the Company with nominal assets and nominal liabilities, (ii) the liquidation or dissolution of a Company
Indenture Party (other than the Company) or any of its wholly-owned Subsidiaries so long as all of the assets (including any interest in any Stock) of such liquidating or dissolving Company Indenture Party or Subsidiary are transferred to a Company
Indenture Party that is not liquidating or dissolving, or (iii) the liquidation or dissolution of a Subsidiary of the Company that is not a Company Indenture Party (other than any such Subsidiary the Stock of which (or any portion thereof) is
subject to a Lien in favor of the Collateral Trustee) so long as all of the assets of such liquidating or dissolving Subsidiary are transferred to a Subsidiary of the Company that is not liquidating or dissolving; 

(c) suspend or cease operation of a substantial portion of its or their business, except as permitted pursuant to Sections
5.03(a) or (b) above or in connection with the transactions permitted pursuant to Section 5.04. 

(d) form or acquire any (i) direct Subsidiary, (ii) indirect Subsidiary in the United States, or (iii) indirect
Subsidiary in a Foreign Jurisdiction unless (A) the applicable Company Indenture Party provides the Collateral Trustee and Trustee (and Trustee shall promptly deliver to each Holder who so requests to receive the following) with written notice
of the formation of such Subsidiary within ten (10) days after such formation, (B) the applicable Company Indenture Party provides the Collateral Trustee with copies of all organizational and formation documents related thereto as the
Collateral Trustee or the Required Holders may request in their Permitted Discretion, (C) the applicable Company Indenture Party complies with Section 7.07 in connection with the formation and/or acquisition of such
Subsidiary and (D) any such acquisition (if applicable) is otherwise permitted hereunder, including without limitation, Section 5.09. 

Section 5.04. Disposal of Assets. Other than Permitted Dispositions or transactions expressly permitted by
Section 5.03 or Article 14, sell, assign (by operation of law or otherwise) or otherwise dispose of, or grant any option with respect to, any of the Collateral or any other asset. The Collateral Trustee and the
Required Holders shall not be deemed to have consented to any sale or other disposition of any of the Collateral or any other asset except as expressly permitted in this Indenture or the Security Documents. 

  
 64 

 Section 5.05. Change of Name. No Company Indenture Party shall change the
name, organizational identification number, state of organization, organizational identity or “location” for purposes of Section 9-307 of the Code of any Company Indenture Party, in each case,
other than as permitted under Section 4.3 of the Security Agreement. 
 Section 5.06. Nature of Business.
Make any change in the nature of its or their business as conducted on the date of this Indenture or acquire any properties or assets that are not reasonably related to the conduct of such business activities; provided, however,
that the foregoing shall not prevent the Company or any other Company Indenture Party or any of its Subsidiaries from engaging in any business that is reasonably related or ancillary to its business. 

Section 5.07. Prepayments. Except in connection with Refinancing Indebtedness (or other refinancing) permitted under the
definition of Permitted Indebtedness,

payments of regularly scheduled interest or any “Additional Interest” due thereunder to the extent permitted (or not otherwise prohibited) by the Existing Intercreditor Agreement, (y) the discharge of the Existing Senior Notes
Indenture at any time after the date hereof in accordance with Article 10 of the Existing Senior Notes Indenture or redemption of the notes issued pursuant to the Existing Senior Notes Indenture on the stated maturity date of the Existing Senior

together with accrued and unpaid interest thereon outstanding plus an amount equal to the interest payable to the stated maturity date. 

  
 65 

 Section 5.08. Amendments. Directly or indirectly, amend, modify, or
change any of the terms or provisions of the Governing Documents of any Company Indenture Party or any of its Subsidiaries if the effect thereof, either individually or in the aggregate, could reasonably be expected to be materially adverse to the

by the Company, upon fair and reasonable terms, and no less favorable than would be obtained in a comparable arm’s length transaction with a non-Affiliate (or, if no such comparable transaction is
available, that is otherwise fair to the Company or the applicable Company Indenture Party), (iii) transactions among the Company and the Company Indenture Parties and (iv) any transaction which does not exceed $2,000,000 in amount (including

bank, appraiser or auditor, stating that such transaction or series of related transactions is (A) fair to the Company and its Subsidiaries from a financial point of view taking into account all relevant circumstances or (B) on terms,
taken as a whole, not materially less favorable than might have been obtained in a comparable transaction at such time on an arm’s length basis from a Person who is not an Affiliate.

related transactions) with an Affiliate is valued at or in excess of $5 million, a majority of the independent members of the Board of Directors of the applicable Company Indenture Party, must conclude in good faith (and, cause an
Officers’ Certificate to that effect to be delivered Trustee) that such transaction was undertaken upon fair and reasonable terms, no less favorable (to Company or such Subsidiary, as applicable) than would have been obtained in a comparable

Section 5.16, the Company, in its sole discretion, may divide or classify and from time to time divide, re-divide, classify and reclassify such Permitted Distributions among such
clauses and/or paragraphs above in any manner in compliance with this Section 5.16. 
 Section 5.17.
[Intentionally Omitted]. 
 ARTICLE 6 

Collateral and Security 

Section 6.01. Security Interest. The Obligations will be secured by a perfected Lien on the Collateral, subject to the
Permitted Liens and the Intercreditor Agreement, as provided in the Security Documents. The Collateral will also secure certain of the Company’s and the Guarantors’ existing obligations under the Term Documents and the ABL Documents,
subject to the Intercreditor Agreement. Under the terms of the Intercreditor Agreement, the proceeds of any collection, sale, disposition or other realization of Collateral received in connection with the exercise of remedies (including
distributions of cash, securities or other property on account of the value of the Collateral in a bankruptcy, insolvency, reorganization or similar proceedings) will be applied in the order of priority set forth in the Intercreditor Agreement. 

Section 6.02. Security Documents. In order to secure the Obligations, the Company Indenture Parties have entered into and
delivered to the Collateral Trustee the Security Agreement and the other Security Documents, in each case, to which it is a party, to create the Liens on the Collateral securing their respective Obligations. In the event of a conflict between the
terms of this Indenture and the Security Documents in regards to the Collateral, the Security Documents shall control. The Company will take, and will cause its Subsidiaries to take any and all actions (including those that may be requested by the
Trustee or the Collateral Trustee) reasonably required to cause the Security Documents to create and maintain, as security for the obligations of the Company hereunder, a valid and enforceable perfected Lien in and on all the Collateral, in favor of
the Collateral Trustee for the benefit of the Holders, the Trustee and the Collateral Trustee, subject to Permitted Liens and the Intercreditor Agreement. 

  
 68 

 Section 6.03. Authorization of Actions to Be Taken. 

(a) Each Holder of Notes, by its acceptance thereof, hereby designates and appoints the Collateral Trustee as its agent under
this Indenture and the Security Documents and each Holder by acceptance of the Notes consents and agrees to the terms of each Security Document, as originally in effect and as amended, supplemented or replaced from time to time in accordance with
its terms or the terms of this Indenture, authorizes and directs the Collateral Trustee to enter into the Security Documents, and irrevocably authorizes and empowers the Collateral Trustee to perform its obligations and duties, exercise its rights
and powers and take any action permitted or required thereunder that are expressly delegated to the Collateral Trustee by the terms of this Indenture and the Security Documents. The Collateral Trustee shall hold (directly or through any agent) and
is directed by each Holder to so hold, and shall be entitled to enforce on behalf of the Holders all Liens on the Collateral created by the Security Documents for their benefit. 

(b) Subject to the provisions of the applicable Security Documents and the Intercreditor Agreement, the Trustee and each
Holder, by acceptance of any Notes, agrees that (x) the Collateral Trustee may, in its sole discretion and without the consent of the Trustee or the Holders, take all actions it deems necessary or appropriate in order to (i) preserve the
Collateral or rights under the Security Documents and (ii) collect and receive any and all amounts payable in respect of the Obligations of the Company and the Guarantors hereunder and under the Indenture Documents and (y) the Collateral
Trustee shall have power to institute and to maintain such suits and proceedings as it may deem expedient to protect or enforce the Liens securing the Obligations and/or to prevent any impairment of the Collateral by any act that may be unlawful or
in violation of the Indenture Documents, and such suits and proceedings as the Collateral Trustee may deem expedient to preserve or protect its interests and the interests of the Holders in the Collateral (including the power to institute and
maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such
enactment, rule or order would impair the security interest thereunder or be prejudicial to the interests of the Collateral Trustee, the Holders or the Trustee). Notwithstanding the foregoing, the Collateral Trustee may, at the expense of the
Company, request the direction of the Holders with respect to any such actions and upon receipt of the written consent of the Required Holders, shall take such actions; provided that all actions so taken shall, at all times, be in conformity
with the requirements of the Intercreditor Agreement, if applicable. Until the Notes and the other Obligations are discharged in full or are otherwise no longer outstanding, all remedies and Enforcement Actions in respect of the Collateral and any
foreclosure actions in respect of any Liens on the Collateral, and all actions, undertakings or consents by the Collateral Trustee in respect of the Collateral, in each case, shall be undertaken solely at the instruction of the Required Holders and
subject to the Intercreditor Agreement. 

  
 69 

 Section 6.04. Release of Collateral. 

(a) The Liens securing the Obligations on the applicable Collateral shall be automatically terminated and released without
further action by any party (other than satisfaction of any requirements in the Security Documents, if any), in whole or in part: (i) upon any Disposition of any portion of Collateral in accordance with a Disposition permitted under the terms
of any Indenture Document (other than a Disposition to a Company Indenture Party); (ii) upon discharge of this Indenture and the other Indenture Documents in accordance with Article 3; (iii) at the direction of the Supermajority Holders; or
(iv) if the Collateral is owned by a Guarantor, upon release of such Guarantor from the Guaranteed Obligations in accordance with the provisions hereof. 

(b) Without the necessity of any consent of or notice to the Trustee or any Holder of the Notes, any Company Indenture Party
may request and instruct the Collateral Trustee to, on behalf of each Holder of Notes, (i) execute and deliver to any Company Indenture Party, as the case may be, for the benefit of any Person, such release documents as may be reasonably
requested, of all Liens held by the Collateral Trustee in any Collateral securing the Obligations, and (ii) deliver any such assets in the possession of the Collateral Trustee to any Company Indenture Party, as the case may be; and Collateral
Trustee shall promptly take such actions provided that any such release complies with and is expressly permitted in accordance with the terms of this Indenture, the Intercreditor Agreement and the Security Documents and is accompanied by an
Officers’ Certificate and Opinion of Counsel. 
 (c) The release of any Collateral from the Liens securing the
Obligations or the release of, in whole or in part, the Liens securing the Obligations created by any of the Security Document will not be deemed to impair the Liens securing the Obligations in contravention of the provisions hereof if and to the
extent the Collateral or the Liens securing the Obligations are released pursuant to the terms of this Indenture and the applicable Security Documents. Each of the Holders of the Notes acknowledges that a release of Collateral or Liens securing the
Obligations strictly in accordance with the terms of this Indenture, the Intercreditor Agreement and the Security Documents will not be deemed for any purpose to be an impairment of the Security Documents or otherwise contrary to the terms of this
Indenture. 
 Section 6.05. Application of Proceeds of Collateral. 

(a) Upon any realization upon the Collateral from the exercise of any rights or remedies under any Security Document or any
other agreement with any Company Indenture Party which secures any of the Obligations, the proceeds thereof shall be applied in accordance with Section 9.05 of this Indenture. 

(b) Each of the Collateral Trustee and the Trustee is authorized and empowered to receive any funds collected or distributed
under the Intercreditor Agreement and the Security Documents and to apply according to the provisions of this Indenture, subject to the Intercreditor Agreement. 

  
 70 

 Section 6.06. Collateral Trustee. 

(a) Subject to the provisions of Section 10.01, neither the Trustee, nor the Collateral Trustee nor
any of their respective officers, directors, employees, attorneys or agents shall be responsible or liable (i) for the legality, enforceability, effectiveness or sufficiency of the Security Documents, for the creation, perfection, priority,
sufficiency, maintenance, renewal or protection of any Lien, or for any defect or deficiency as to any such matters, or (ii) for any failure to demand, collect, foreclose or realize upon or otherwise enforce any of the Liens or Security
Documents or any delay in doing so; except, in the case of the Collateral Trustee, to the extent such action or omission constitutes gross negligence, bad faith or willful misconduct (as determined by a final order of a court of competent
jurisdiction that is not subject to appeal) on the part of the Collateral Trustee, (iii) for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the title, for insuring the
Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral or (iv) for the legality, enforceability, effectiveness or sufficiency of the Intercreditor
Agreement, Intercompany Subordination Agreement, or any subordination agreement or other similar agreement entered into in connection with this Indenture. 

(b) The rights, privileges, protections, immunities and benefits given to the Trustee under this Indenture, including, without
limitation, its right to be indemnified and compensated and all other rights, privileges, protections, immunities and benefits set forth in Article 10, are extended to the Collateral Trustee, and its agents, receivers and attorneys, and shall
be enforceable by, the Collateral Trustee, as if fully set forth in this Section 6.06 with respect to the Collateral Trustee, except that the Collateral Trustee shall only be liable for (and shall be indemnified and held
harmless to the extent such Losses do not constitute) its gross negligence, bad faith or willful misconduct (as determined by a final order of a court of competent jurisdiction that is not subject to appeal). In acting under any Security Document or
the Intercreditor Agreement, the Collateral Trustee shall enjoy the rights, privileges, protections, immunities and benefits that are extended to the Collateral Trustee hereunder. 

(c) Beyond the exercise of reasonable care in the custody of Collateral in its possession, the Collateral Trustee will have no
duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto. In addition, the
Collateral Trustee will not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any Liens on
the Collateral, unless specifically requested by the Required Holders. If, at the direction of the Required Holders, the Trustee or Collateral Trustee files or records any Security Documents or any related UCC financing statement or other similar
documents, such filing or recording by the Trustee or Collateral Trustee at the direction of the Required Holders shall be deemed done by Trustee or Collateral Trustee without representation or warranty by the Trustee or the Collateral Trustee (and
the Trustee and the Collateral Trustee disclaim any representation or warranty as to the validity, effectiveness, priority, perfection or otherwise). The Collateral Trustee will be deemed to have exercised reasonable care in the custody of the
Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords property held by it as a collateral agent or any similar arrangement, and the Collateral Trustee will not be liable or responsible for
any loss or diminution in the value of any of the Collateral by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Collateral Trustee in good faith. 

  
 71 

 (d) The Collateral Trustee shall not have any duty to ascertain or inquire
as to the performance or observance of any of the terms of this Indenture or any Indenture Document by the Company or any Company Indenture Party or any other Person that is a party thereto or bound thereby. 

(e) The Collateral Trustee shall not be required to acquire title to an asset for any reason and shall not be required to carry
out any fiduciary or trust obligation for the benefit of another. The Collateral Trustee is not a fiduciary and shall not be deemed to have assumed any fiduciary obligation. If the Collateral Trustee in its sole discretion believes that any
obligation to take or omit to take any action may cause the Collateral Trustee to be considered an “owner or operator” under any environmental laws or otherwise cause the Collateral Trustee to incur, or be exposed to, any environmental
liability or any liability under any other federal, state or local law, the Collateral Trustee reserves the right, instead of taking such action, either to resign as Collateral Trustee or to arrange for the transfer of the title or control of the
asset to a court appointed receiver. The Collateral Trustee will not be liable to any Person for any environmental liability or any environmental claims or contribution actions under any federal, state or local law, rule or regulation by reason of
the Collateral Trustee’s actions and conduct as authorized, empowered and directed hereunder or relating to any kind of discharge or release or threatened discharge or release of any hazardous materials into the environment. 

(f) The Collateral Trustee may resign or be replaced in accordance with the procedures set forth in
Section 10.09 hereof, except that references to the Trustee in such section shall be deemed to be references to the Collateral Trustee for this purpose. If the Collateral Trustee consolidates, merges or converts into, or
transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act will be the successor Collateral Trustee. 

(g) At all times when the Trustee is not itself the Collateral Trustee, the Company shall deliver to the Trustee copies of all
Security Documents delivered to the Collateral Trustee and copies of all documents delivered to the Collateral Trustee pursuant to the Security Documents. 

Section 6.07. Trust Indenture Act Requirements; Opinion of Counsel; Certificates of the Company. The Company Indenture Parties
shall furnish to the Collateral Trustee and the Trustee at least thirty (30) days prior to each anniversary of the Issue Date, an Opinion of Counsel, dated as of such date, stating that, in the opinion of such counsel, (A) action has been
taken with respect to the filing of record by each applicable Company Indenture Party all UCC financing statements, continuation statements or amendments as is necessary to maintain the Liens on the portion of the Collateral securing the Obligations
for which perfection of such Lien may be accomplished under the Code by filing a UCC financing statement, continuation statement or financing statement amendment in the office of the Secretary of State of the State of Delaware (or such other
applicable filing office) and the payment of all applicable filing fees and (B) based on relevant laws as in 

  
 72 

 
effect on the date of such Opinion of Counsel, continuation statements and financing statement amendments have been filed of record that are necessary as of such date and during the succeeding 18
months fully to preserve and perfect the Liens on the portion of the Collateral securing the Obligations for which perfection of such Lien may be accomplished under the Code by filing a UCC financing statement, continuation statement or financing
statement amendment in the office of the Secretary of State of the State of Delaware (or such other applicable filing office) and the payment of all applicable filing fees and such Opinion of Counsel may contain customary qualifications and
exceptions and may rely on an Officers’ Certificate (as to factual matters only); provided that if there is a required filing of a continuation statement or other instrument within such 18 month period and such continuation statement or
amendment is not effective if filed at the time of the Opinion of Counsel, such Opinion of Counsel may so state that and in that case the Company Indenture Parties shall cause a continuation statement or amendment to be timely filed so as to
maintain such Liens and security interests securing the Obligations. 
 ARTICLE 7 

Guarantees 
 Section 7.01.
Subsidiary Guarantees. 
 (a) Subject to this Article 7, each of the Guarantors hereby, jointly and severally,
unconditionally guarantees, on a senior secured basis, as primary obligors and not as a surety, to each Holder (and its successors and assigns) of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns,
irrespective of the validity and enforceability of this Indenture, the Notes, the Indenture Documents and/or the Obligations of the Company, that: 

(i) the principal of and interest on the Notes shall be promptly paid in full or performed when due, whether at maturity, by
acceleration, redemption or otherwise, and interest on the overdue principal of and interest (including but not limited to any interest, fees, costs or charges that would accrue but for the provisions of Bankruptcy Code after any Insolvency
Proceeding), on the Notes, if any, if lawful, and all other Obligations of the Company and the Company Indenture Parties to the Holders, the Trustee or to the Collateral Trustee under this Indenture, the other Indenture Documents and the Note
Purchase Agreement shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; 
 (ii)
in case of any extension of time of payment or renewal of any Notes or the payment or performance any of other Obligations, the same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal,
subject to any applicable grace period, whether at stated maturity, by acceleration, upon repurchase or otherwise (such obligations in clauses (i) and (ii) being herein collectively called the “Guaranteed Obligations”). 

(b) Failing payment when so due of any amount so guaranteed for whatever reason, the Guarantors will be jointly and severally
obligated to pay the same immediately. An Event of Default under this Indenture or the Notes shall constitute an event of default under the Subsidiary Guarantees, and shall entitle the Holders to accelerate the obligations of the Guarantors
hereunder in the same manner and to the same extent as the obligations of the Company. 

  
 73 

 (c) The Guarantors hereby agree that their obligations hereunder shall be
absolute, irrevocable and unconditional, irrespective of the value, genuineness, validity, regularity or enforceability of the Notes, this Indenture, the Indenture Documents or any other agreement or instrument referred to herein or therein, 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 Company, any action to enforce the same or any other circumstance (other than
complete performance) which might otherwise constitute a legal or equitable discharge or defense of a surety or Guarantor, all to the fullest extent permitted by law. Without limiting the generality of the foregoing, it is agreed that the occurrence
of any one or more of the following shall not alter or impair the liability of the Guarantors hereunder which remain absolute, irrevocable and unconditional under any and all circumstances as described above, to the fullest extent permitted by law:

 (i) at any time or from time to time, without notice to the Guarantors, the time for any performance of or compliance with
any of the Guaranteed Obligations shall be extended, or such performance or compliance shall be waived; 
 (ii) any of the
acts mentioned in any of the provisions of this Indenture or the Notes, if any, or any other agreement or instrument referred to herein or therein shall be done or omitted; 

(iii) the maturity of any of the Guaranteed Obligations shall be accelerated, or any of the Guaranteed Obligations shall be
amended in any respect, or any right under the Indenture, Notes, or any other agreement or instrument referred to herein or therein shall be amended or waived in any respect or any other guarantee of any of the Guaranteed Obligations or any security
therefor shall be released or exchanged in whole or in part or otherwise dealt with; 
 (iv) any Lien or security interest
granted to, or in favor of any Holder, the Collateral Trustee or the Trustee as security for any of the Guaranteed Obligations shall fail to be perfected; or 

(v) the release of any other Guarantor. 

(d) Each Guarantor further, to the fullest extent permitted by law, hereby waives diligence, presentment, demand of payment,
filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that its Subsidiary Guarantee will not be
discharged except by complete performance of the obligations contained in the Notes and this Indenture. 

  
 74 

 (e) Until terminated in accordance with
Section 7.03, each Subsidiary Guarantee shall, to the fullest extent permitted by law, remain in full force and effect and continue to be effective should any petition be filed by or against the Company for liquidation,
reorganization, should the Company become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Company’s assets, and shall, to the fullest extent
permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the
Notes or Subsidiary Guarantees, whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment had not been made. In the event that any payment or any part thereof, is rescinded, reduced,
restored or returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned. 

(f) Each Guarantor further agrees that, as between the Guarantors, 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 Section 9.02 hereof (and shall be deemed to have become automatically due and payable in the circumstances in said
Section 9.02) for the purposes of its Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed thereby, and (b) in the event
of any declaration of acceleration of such obligations as provided in Section 9.02 hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purpose of its
Subsidiary Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Subsidiary
Guarantees. 
 (g) Each Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’
fees) incurred by the Trustee, the Collateral Trustee or any Holder in enforcing any rights under the Indenture Documents and the Note Purchase Agreement. 

(h) Each Guarantor shall be subrogated to all rights of Holders against the Company in respect of any amounts paid by any
Guarantor pursuant to the provisions of this Section 7.01; provided that, no Guarantor shall be entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then due
and payable by the Company under this Indenture, the Notes or the Indenture Documents shall have been paid in full in cash. 

(i) Each payment to be made by a Guarantor in respect of its Subsidiary Guarantee shall be made without set-off, counterclaim, reduction or diminution of any kind or nature. 
 (j)
Notwithstanding any other provisions set forth herein, SAE Acquisition (U.S.), LLC shall not constitute a Guarantor or Company Indenture Party hereunder (or otherwise be subject to the any of the provisions hereof) unless and until the Closing Date
Acquisition Obligations (other than contingent indemnification obligations for which no claim has been asserted) have been paid in full in cash. 

  
 75 

 Section 7.02. Execution and Delivery. 

(a) To evidence its Subsidiary Guarantee set forth in Section 7.01 hereof, each Guarantor hereby
agrees that this Indenture (or a supplemental indenture in the form of Exhibit B hereto) shall be executed on behalf of such Guarantor by one of its authorized officers. 

(b) Each Guarantor hereby agrees that its Subsidiary Guarantee set forth in Section 7.01 hereof shall
remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Subsidiary Guarantee on the Notes. If an officer whose signature is on this Indenture (or a supplemental indenture) no longer holds that office at
the time the Trustee authenticates a Note, the Subsidiary Guarantee of such Guarantor shall be valid nevertheless. 
 (c) The
delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Subsidiary Guarantee set forth in this Indenture on behalf of the Guarantors. 

Section 7.03. Releases of Subsidiary Guarantees. 

(a) The Subsidiary Guarantee of a Guarantor shall be automatically and unconditionally released: (1) in connection with
(x) any Disposition (including by way of merger or consolidation) of the Capital Stock of such Guarantor (or the Capital Stock of the direct parent of such Guarantor) to a Person that is not (either before or after giving effect to such
transaction) a Company Indenture Party, to the extent such sale is permitted hereunder or to the extent such Capital Stock constitutes Excluded Property or (y) any sale or other Disposition of all or substantially all of the properties or
assets of that Guarantor, by way of merger, consolidation or otherwise solely to the extent that such sale or other Disposition is permitted pursuant to Section 14.02; (2) the liquidation or dissolution of such Guarantor;
provided that no Event of Default occurs as a result thereof or has occurred or is continuing; (3) upon satisfaction and discharge of this Indenture in accordance with Article 3 or (4) upon payment of the Obligations in full in
immediately available funds, provided, in each case that the transaction is permitted under this Indenture and is otherwise carried out pursuant to, and in accordance with, all other applicable provisions of this Indenture. 

(b) Upon delivery by the Company to the Trustee of an Officers’ Certificate and Opinion of Counsel to the effect that any
of the conditions described in the foregoing clauses (1), (2), or (3) of Section 7.03(a) has occurred and the conditions precedent to such transactions provided for in this Indenture have been complied with, the
Trustee shall execute any documents reasonably requested by the Company in order to evidence the release of any Guarantor from its obligations under its Subsidiary Guarantee. Any Guarantor not released from its obligations under its Subsidiary
Guarantee shall remain liable for the full amount of principal of and interest, premium, and Additional Interest, if any, on, the Notes and for the other obligations of such Guarantor under this Indenture as provided in this Article 7. 

  
 76 

 (c) Further, the Subsidiary Guarantees are not convertible and will
automatically terminate when the Notes are all converted in full in accordance with Article 17. 
 Section 7.04. Instrument
for the Payment of Money. Each Guarantor hereby acknowledges that the guarantee in this Article 7 constitutes an instrument for the payment of money, and consents and agrees that any Holder (to the extent that the Holder is
otherwise entitled to exercise rights and remedies hereunder) or the Trustee, at its sole option, in the event of a dispute by such Guarantor in the payment of any moneys due hereunder, shall have the right to bring a motion-action under New York
CPLR Section 3213 to the extent permitted thereunder. 
 Section 7.05. Limitation on Guarantor Liability.
Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of any
bankruptcy law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Subsidiary Guarantee. The obligations of each Guarantor under its Subsidiary Guarantee
will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of
the obligations of such other Guarantor under its Subsidiary Guarantee or pursuant to its contribution obligations under this Indenture, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent
conveyance or fraudulent transfer under federal or state law and not otherwise being void or voidable under any similar laws affecting the rights of creditors generally. 

Section 7.06. “Trustee” to Include Paying Agent. In case at any time any Paying Agent other than
the Trustee shall have been appointed and be then acting hereunder, the term “Trustee” as used in this Article 7 shall in each case (unless the context shall otherwise require) be construed as extending to and including such Paying
Agent within its meaning as fully and for all intents and purposes as if such Paying Agent were named in this Article 7 in place of the Trustee. 

Section 7.07. Guaranty and Collateral Supplements. If any Company Indenture Party creates or acquires a wholly-owned
Domestic Subsidiary (other than (x) an Excluded Subsidiary or (y) a Foreign Subsidiary Holding Company) on or after the date hereof, such Company Indenture Party shall cause such Domestic Subsidiary to be a Guarantor hereunder and to join
the Security Agreement (and all other applicable Security Documents) as a grantor thereunder for all purposes to secure its Guaranteed Obligations with Liens on substantially all of its assets for the benefit of the Secured Parties. In furtherance
of the foregoing, such wholly-owned Domestic Subsidiary shall: 
 (a) execute and deliver to the Trustee and the Collateral
Trustee a supplemental indenture in the form attached hereto as Exhibit B pursuant to which such Subsidiary shall unconditionally guarantee the Obligations on the terms set forth in this Article 7; 

  
 77 

 (b) execute and deliver an assumption agreement in the form attached as
Annex 1 to the Security Agreement and all other supplements or joinders, as applicable, to the other applicable Security Documents in order to grant a Lien in the Collateral owned by such Subsidiary to the same extent as that set forth in this
Indenture and the Security Documents and take all actions required by the Security Documents to perfect such Lien; and 
 (c)
deliver to the Trustee and Collateral Trustee an Officers’ Certificate and an Opinion of Counsel that such supplemental indenture and the other documents described in clause (1) and (2) above comply with the requirements of this
Indenture, the Intercreditor Agreement, and the Security Documents, are permitted or authorized by this Indenture and have been duly authorized, executed and delivered by such Subsidiary and constitute a valid and legally binding and enforceable
obligations of such Subsidiary, subject to customary exceptions. 
     Thereafter, such Subsidiary shall be a Guarantor
for all purposes of this Indenture. 
 ARTICLE 8 

Lists of Holders and Reports by the Company and the Trustee 

Section 8.01. Lists of Holders. 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. If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least seven 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 of Notes, including names and addresses of Holders in the possession of any Paying Agent other than the
Trustee. 
 ARTICLE 9 

Defaults and Remedies 

Section 9.01. Events of Default. Each of the following events shall be an “Event of Default” with respect to the
Notes: 
 (a) Default (i) in the payment when due (at maturity, upon redemption or otherwise) of the principal of, or
premium, if any, on, the Notes or (ii) for 30 days in the payment when due of interest or any other Obligations (other than principal or premium, if any), if any, with respect to the Notes;

 78 

 (d) If the Company fails to issue a Fundamental Change Company Notice in
accordance with Section 18.01(b) or notice of a specified corporate event in accordance with Section 16.01 or Section 16.02, in each case, when due, if such failure
continues for three Business Days; 
 (e) If any Company Indenture Party or any of its Subsidiaries (other than its Foreign
Subsidiaries): 
 (i) fails to perform or observe any covenant or other agreement contained in any of
(i) Section 4.08 (solely if any Company Indenture Party or any of its Subsidiaries is not in good standing in its jurisdiction of organization), 4.10(a) (solely with respect to F.I.C.A., F.U.T.A., federal income
Taxes and any other Taxes or assessments the non-payment of which may result in a Lien having priority over Liens securing the Obligations), 4.10(b), 4.11, 4.16 or 4.19, (ii)
Article 5, or (iii) the Intercreditor Agreement; 
 (ii) fails to perform or observe any covenant or other

and any other Taxes or assessments the non-payment of which may result in a Lien having priority over Liens securing the Obligations), 4.14 or 4.15 and such failure continues for a period of 30
days after the earlier of (i) the date on which such failure shall first become known to or should have been known by any Officer of any Company Indenture Party or (ii) the date on which written notice thereof is given to any Company
Indenture Party by the Trustee or the Collateral Trustee; or 
 (iii) fails to comply with its obligations under Article
14; 
 (iv) fails to perform or observe any covenant or other agreement contained in this Indenture, or in any of the

 Section 9.02. Acceleration; Rescission and Annulment. 

(a) If one or more Events of Default shall have occurred and be continuing (whatever the reason for such Event of Default and
whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body), then, and in each and every such
case (other than an Event of Default specified in Section 9.01(e)(vi) or (vii) with respect to any Company Indenture Party or any of its Domestic Subsidiaries, unless the principal of all of the Notes shall have
already become due and payable), either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, by notice in writing to the Company (and to the Trustee if given by Holders), may declare 100% of the
principal of, and accrued and unpaid interest on, all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable, anything contained in this Indenture or in
the Notes to the contrary notwithstanding. If an Event of Default specified in Section 9.01(e)(vi) or Section 9.01(e)(vii) with respect to any Company Indenture Party or any of its Subsidiaries
occurs and is continuing, 100% of the principal of, and accrued and unpaid interest, if any, on, all Notes shall become and shall automatically be immediately due and payable. 

(b) Section 9.02(a), however, is subject to the conditions that if, at any time after the principal
of, and any accrued and unpaid interest on, all of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Company
shall pay or shall deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid interest upon all Notes and the principal of any and all Notes that shall have become due otherwise than by acceleration (with interest on overdue
installments of accrued and unpaid interest to the extent that payment of such interest is enforceable under applicable law, and on such principal, at the rate borne by the Notes plus one percent at such time) and amounts due to the Trustee and the
Collateral Trustee 

  
 81 

 
pursuant to Section 6.06 and Section 10.06, and if (1) rescission would not conflict with any judgment or decree of a court of competent
jurisdiction and (2) any and all existing Events of Default under this Indenture, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes that shall have become due solely by such acceleration, shall have
been cured or waived pursuant to Section 9.09, then and in every such case (except as provided in the immediately succeeding sentence) the Holders of a majority in aggregate principal amount of the Notes then outstanding,
by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and annul such declaration and its consequences and such Default shall cease to exist, and any Event of Default
arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent
thereon. Notwithstanding anything to the contrary herein, no such waiver or rescission and annulment shall extend to or shall affect any Default or Event of Default resulting from (i) the nonpayment of the principal (including the Fundamental
Change Repurchase Price, if applicable) of, the Redemption Price of (if applicable), or accrued and unpaid interest (including any Additional Interest) on any Notes, (ii) a failure to repurchase any Notes when required or (iii) a failure
to pay or deliver, as the case may be, the consideration due upon conversion of the Notes. 
 Section 9.03. Additional Interest.

 (a) Notwithstanding anything in this Indenture or in the Notes to the contrary, to the extent the Company elects, the sole
remedy for an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.05 or 4.06(b) shall (x) for the first 90 days after the occurrence of such an Event
of Default, consist exclusively of the right to receive Additional Interest on the Notes at a rate equal to 0.25% per annum of the principal amount of the Notes outstanding for each day during such 90-day
period on which such Event of Default is continuing beginning on, and including, the date on which such an Event of Default first occurs and (ii) for the period from, and including, the 91st day after the occurrence of such an Event of Default
to, and including, the 180th day after the occurrence of such an Event of Default, consist exclusively of the right to receive Additional Interest on the Notes at a rate equal to 0.50% per annum of the principal amount of the Notes outstanding for
each day during such additional 90-day period on which such Event of Default is continuing. Additional Interest payable pursuant to this Section 9.03 shall be in addition to, not in
lieu of, any liquidated damages payable pursuant to the Registration Rights Agreement. If the Company so elects, it shall advise Trustee in writing and such Additional Interest shall be payable in the same manner and on the same dates as the stated
interest payable on the Notes. On the 181st day after such Event of Default (if the Event of Default relating to the Company’s failure to file is not cured or waived prior to such 181st day), the Notes shall be immediately subject to
acceleration as provided in Section 9.02. The provisions of this paragraph will not affect the rights of Holders of Notes in the event of the occurrence of any Event of Default other than the Company’s failure to
comply with its obligations as set forth in Section 4.05 or 4.06(b). In the event the Company does not elect to pay Additional Interest following an Event of Default in accordance with this
Section 9.03 or the Company elected to make such payment but fails to pay the Additional Interest when due and such failure becomes an Event of Default, the Notes shall be subject to acceleration as provided in
Section 9.02. 

  
 82 

 (b) In order to elect to pay Additional Interest as the sole remedy during
the first 180 days after the occurrence of any Event of Default described in the immediately preceding paragraph, the Company must notify all Holders of the Notes, the Trustee and the Paying Agent of such election prior to the beginning of such 180-day period. Upon the failure to timely give such notice, the Notes shall be subject to acceleration as provided in Section 9.02. 

Section 9.04. Payments of Notes on Default; Suit Therefor. 

(a) If an Event of Default described in Section 9.01(a), (b) or (c) shall have
occurred and be continuing, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes for principal (including the Fundamental Change Repurchase
Price, if applicable), the Redemption Price (if applicable) and interest, if any, with interest on overdue installments of accrued and unpaid interest to the extent that payment of such interest is enforceable under applicable law, and on any
overdue principal (including the Fundamental Change Repurchase Price or the Redemption Price, if applicable), at the rate borne by the Notes plus one percent at such time, and, in addition thereto, such further amount as shall be sufficient to cover
any amounts due to the Trustee and the Collateral Trustee under Section 6.06 and Section 10.06. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own
name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company, any other Company
Indenture Party or any other obligor upon the Notes and collect the moneys or property adjudged or decreed to be payable in the manner provided by law out of the property of the Company, any other Company Indenture Party or any other obligor upon
the Notes, wherever situated. 
 (b) In the event there shall be pending proceedings for the bankruptcy or for the
reorganization of the Company, any other Company Indenture Party or any other obligor on the Notes under Title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company, any other Company Indenture Party or such other obligor, the property of the Company, any other Company Indenture Party or such other
obligor, or in the event of any other judicial proceedings relative to the Company, any other Company Indenture Party or such other obligor upon the Notes, or to the creditors or property of the Company, any other Company Indenture Party or such
other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the
provisions of this Section 9.04, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal (including the Fundamental Change

  
 83 

 
Repurchase Price, if applicable), the Redemption Price (if applicable) and accrued and unpaid interest (including Additional Interest), if any, in respect of the Notes, and, in case of any
judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem 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 of the Holders allowed in such judicial proceedings relative to the Company, any other Company Indenture Party or any other obligor on the Notes, its or their
creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due to the Trustee hereunder; and any receiver,
assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as administrative expenses, 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 it for reasonable compensation, expenses, advances and disbursements, including agents and counsel fees, and including any other amounts due to the
Trustee hereunder, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment
of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the Holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or
under any plan of reorganization or arrangement or otherwise. 
 (c) Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting such Holder or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding. 
 (d) All rights of action and of asserting claims under this
Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee (in any capacity), its agents
and counsel, be for the ratable benefit of the Holders of the Notes. 
 (e) In any proceedings brought by the Trustee (and in
any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the
Notes parties to any such proceedings. 

  
 84 

 (f) In case the Trustee shall have proceeded to enforce any right under this
Indenture and such proceedings shall have been discontinued or abandoned because of any waiver pursuant to Section 9.09 or any rescission and annulment pursuant to Section 9.02 or for any other
reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Holders and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and
rights hereunder, and all rights, remedies and powers of the Company, the Holders and the Trustee shall continue as though no such proceeding had been instituted. 

Section 9.05. Application of Monies Collected by Trustee. Subject to the Intercreditor Agreement, any monies or property
collected by the Trustee pursuant to this Article 9 with respect to the Notes shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies or property, upon presentation of the several
Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid: 
 (a) First, to
the payment of all amounts due the Collateral Trustee and Trustee (acting in any capacity) hereunder, including under Section 6.06 and Section 10.06; 

(b) Second, to the payment of fees and expenses under the Note Purchase Agreement; 

(c) Third, in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest
on, and any cash due upon conversion of, the Notes in default in the order of the date due of the payments of such interest and cash due upon conversion, as the case may be, with interest (to the extent that such interest has been collected by the
Trustee) upon such overdue payments at the rate borne by the Notes at such time, plus one percent, such payments to be made ratably to the Persons entitled thereto; 

(d) Fourth, in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to
the payment of the whole amount (including, if applicable, the payment of the Redemption Price, the Fundamental Change Repurchase Price, and any cash due upon conversion) then owing and unpaid upon the Notes for principal, the Redemption Price and
interest, if any, and any cash due upon conversion and other amounts then payable on the Notes, with interest on the overdue principal and, to the extent that such interest has been collected by the Trustee, upon overdue installments of interest and
any such cash due upon conversion or other amounts at the rate borne by the Notes at such time plus one percent, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of
such principal (including, if applicable, the Fundamental Change Repurchase Price and the cash due upon conversion), such Redemption Price and such interest without preference or priority of principal over interest, or of interest over principal or
of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal (including, if applicable, the Fundamental Change Repurchase Price and any cash due upon
conversion), such Redemption Price and such accrued and unpaid interest; and 
 (e) Fifth, the remainder, if any, to the
Company. 

  
 85 

 Section 9.06. Proceedings by Holders. 

(a) Except to enforce the right to receive payment of principal (including, if applicable, the Fundamental Change Repurchase
Price), the Redemption Price (if applicable), interest when due, or the right to receive payment or delivery of the consideration due upon conversion, no Holder of any Note shall have any right by virtue of or by availing of any provision of this
Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy
hereunder, unless: 
 (i) such Holder previously shall have given to the Trustee written notice that an Event of Default is
continuing; 
 (ii) Holders of at least 25% in aggregate principal amount of the Notes then outstanding shall have made
written request upon the Trustee to institute such action, suit or proceeding in respect of such Event of Default in its own name as Trustee hereunder; 

(iii) such Holders shall have offered to the Trustee such security or indemnity satisfactory to it against any loss, liability
or expense to be incurred therein or thereby; 
 (iv) the Trustee, for 60 days after its receipt of such notice, request and
offer of such security or indemnity, shall have neglected or refused to institute any such action, suit or proceeding; and 

(v) no written direction that, in the opinion of the Trustee, is inconsistent with such written request shall have been given
to the Trustee by the Required Holders within such 60-day period pursuant to Section 9.09. 

(b) No one or more Holders shall have any right in any manner whatever by virtue of or by availing of any provision of this
Indenture to affect, disturb or prejudice the rights of any other Holder, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and for
the equal, ratable and common benefit of all Holders (except as otherwise provided herein). For the protection and enforcement of this Section 9.06, each and every Holder and the Trustee shall be entitled to such relief as
can be given either at law or in equity. 
 (c) Notwithstanding any other provision of this Indenture and any provision of
any Note, the right of any Holder to receive payment or delivery, as the case may be, of (w) the principal (including Fundamental Change Repurchase Price, if applicable) of, (x) accrued and unpaid interest, if any, on, (y) if
applicable, the Redemption Price of, and (z) the consideration due upon conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in this Indenture, or to institute suit for the enforcement of any
such payment or delivery, as the case may be, on or after such respective dates against the Company shall not be impaired or affected without the consent of such Holder. 

  
 86 

 Section 9.07. Proceedings by Trustee. In case of, and during the
continuation of, an Event of Default, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights,
either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture,
or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law. 
 Section 9.08. Remedies
Cumulative and Continuing. All powers and remedies given by this Article 9 to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and
remedies available to the Trustee or the Holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of
any Holder of any of the Notes to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence
therein; and, subject to the provisions of Section 9.06, every power and remedy given by this Article 9 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed
expedient, by the Trustee or by the Holders. 
 Section 9.09. Direction of Proceedings and Waiver of Defaults by Majority of
Holders. 
 (a) The Required Holders may direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law, this Indenture, the Notes, the Security Documents, the Intercreditor Agreement or
any Subsidiary Guarantee, or that the Trustee determines in good faith is unduly prejudicial to the rights of any other Holder (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 any other Holder) or that would involve the Trustee in personal liability and the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with the Required Holders’ direction.
Prior to taking any action under the Indenture Documents, the Trustee shall be entitled to indemnification satisfactory to it against all losses and expenses caused by taking or not taking such action. 

(b) The Required Holders by written notice to the Trustee may on behalf of all Holders waive any existing Default or Event of
Default and its consequences hereunder, except: 
 (i) a continuing Default or Event of Default in the payment of the
principal, premium, if any, or interest on any Note held by a non-consenting Holder; and 

  
 87 

 (ii) a Default or Event of Default with respect to a provision that under
this Article 9 cannot be amended without the consent of each Holder affected. 
 Section 9.10. Notice of Defaults.
The Trustee shall, within 90 days after the occurrence and continuance of a Default of which the Trustee has knowledge (determined as set forth in Section 10.02), send to all Holders as the names and addresses of such
Holders appear upon the Note Register, notice of such Defaults, unless such Defaults shall have been cured or waived before the giving of such notice; provided that, except in the case of a Default in the payment of the principal of (including the
Fundamental Change Repurchase Price, if applicable), the Redemption Price of (if applicable), or accrued and unpaid interest on, any of the Notes or a Default in the payment or delivery of the consideration due upon conversion, the Trustee shall be
protected in withholding such notice if and so long as it in good faith determines that the withholding of such notice is in the interests of the Holders. 

Section 9.11. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such
proceedings, the Company, the Guarantors, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no
such proceeding has been instituted. 
 Section 9.12. Undertaking to Pay Costs. All parties to this Indenture agree, and
each Holder of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any
action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and
expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 9.12 (to the extent
permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding, or to any suit
instituted by any Holder for the enforcement of the payment of the principal (including, but not limited to, the Fundamental Change Repurchase Price, if applicable) of, the Redemption Price of (if applicable), with respect to, or accrued and unpaid
interest, if any, on any Note on or after the respective due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert any Note, or receive the consideration due upon conversion, in accordance with the
provisions of Article 17.

(a) The Trustee, prior to the occurrence of an Event of Default and after the curing or waiver of all Events of Default that
may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. 

  
 88 

 (b) In the event an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s
own affairs; provided that if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the Holders unless such Holders
have offered to the Trustee indemnity or security satisfactory to it against any loss, liability or expense that might be incurred by it in compliance with such request or direction. 

(c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own grossly negligent
action, its own grossly negligent failure to act or its own willful misconduct, except that: 
 (i) Prior to the occurrence
of an Event of Default and after the curing or waiving of all Events of Default that may have occurred: 
 (A) the duties and
obligations of the Trustee shall be determined solely by the express provisions of this Indenture and applicable law, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this
Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 
 (B) in the
absence of bad faith or willful misconduct on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the
Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or opinions that by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine
the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein); 

(ii) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer(s) of the Trustee,
unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; 
 (iii) the Trustee shall not
be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Required Holders relating to the time, method and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture;

provided, every provision of this Indenture relating to the conduct or affecting the liability of, or affording protection to, the Trustee shall be subject to the provisions of this Section;

of any payment (as to the correctness of amount, entitlement to receive or any other matters relating to payment) or notice effected by the Company or any Paying Agent or any records maintained by any co-Note
Registrar with respect to the Notes; 
 (vi) if any party fails to deliver a notice relating to an event the fact of which,
pursuant to this Indenture, requires notice to be sent to the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred, unless a Responsible Officer of the Trustee had actual
knowledge of such event or unless written notice of any event which is in fact such a Default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the existence of a Default or Event of Default, the
Notes and this Indenture; 
 (vii) in the absence of written investment direction from the Company, all cash received by the
Trustee shall be placed in a non-interest bearing trust account, and in no event shall the Trustee be liable for the selection of investments or for investment losses incurred thereon or for losses incurred as
a result of the liquidation of any such investment prior to its maturity date or the failure of the party directing such investments prior to its maturity date or the failure of the party directing such investment to provide timely written
investment direction, and the Trustee shall have no obligation to invest or reinvest any amounts held hereunder in the absence of such written investment direction from the Company; 

(viii) in the event that the Trustee is also acting as Note Registrar, Paying Agent, Conversion Agent or Transfer Agent
hereunder, the rights and protections afforded to the Trustee pursuant to this Article 10 shall also be afforded to such Note Registrar, Paying Agent, Conversion Agent or Transfer Agent; 

(ix) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or
through agents (including an authenticating agent) or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder; and

 In no event shall the Trustee be liable for any special, indirect, punitive or consequential
loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. The Trustee shall not be charged with knowledge of
any Default or Event of Default with respect to the Notes, unless either (1) a Responsible Officer shall have actual knowledge of such Default or Event of Default or (2) written notice of such Default or Event of Default shall have been

Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this

Section 10.04. Trustee, Paying Agents, Conversion Agents or Note Registrar May Own Notes. The Trustee, any Paying Agent,

 Section 10.06. Compensation and Expenses of Trustee.
The Company and the Guarantors jointly and severally covenant and agree to pay to the Trustee (acting in any capacity) from time to time, and the Trustee shall be entitled to, reasonable compensation for all services rendered by it hereunder in
any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as mutually agreed to in writing between the Trustee and the Company, and the Company will pay or reimburse the Trustee
(acting in any capacity) upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any of the provisions of this Indenture in any capacity thereunder (including the reasonable
compensation and the expenses and disbursements of its agents and counsel and of all Persons not regularly in its employ, for which the Company has received an invoice with reasonably detailed documentation of any such expenses, and court costs)
except any such expense, disbursement or advance as may arise from its gross negligence, willful misconduct or bad faith (as determined by a court of competent jurisdiction in a non-appealable final decision).
The Company and the Guarantors also jointly and severally covenant to indemnify the Trustee in any capacity under this Indenture and any other document or transaction entered into in connection herewith and its agents and any authenticating agent
for, and to hold them harmless against, any loss, claim, damage, liability or expense incurred without gross negligence, or willful misconduct on the part of the Trustee (as determined by a court of competent jurisdiction in a non-appealable 

  
 92 

 
final decision), its officers, directors, agents or employees, or such agent or authenticating agent, as the case may be, and arising out of or in connection with the acceptance or administration
of this Indenture and the performance of their duties hereunder or in any other capacity hereunder, including the costs and expenses of enforcing this Indenture against the Company and the Guarantors (including this
Section 10.06), defending themselves against any claim whether asserted by any Holder, the Company or any Guarantor, or defending themselves against any claim of liability in the premises, including reasonable fees and
expenses of legal counsel limited to one firm and, to the extent so required, one local counsel in each applicable jurisdiction, and court costs. The obligations of the Company and the Guarantors hereunder to compensate or indemnify the Trustee and
to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by the Trustee, except, subject to the effect of
Section 9.05 funds held in trust herewith for the benefit of the Holders of particular Notes. The Trustee’s right to receive payment of any amounts due hereunder shall not be subordinate to any other liability or
indebtedness of the Company. The obligations of the Company and the Guarantors under this Article 10 shall survive the satisfaction and discharge of this Indenture and the earlier resignation or removal or the Trustee. The Company need not
pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The indemnification provided in this Section 10.06 shall extend to the officers, directors, agents and employees of the
Trustee. 
 Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee and its agents and any
authenticating agent incur expenses or render services after an Event of Default specified in Section 9.01(e)(vi) or Section 9.01(e)(vii) occurs, the expenses and the compensation for the services
are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws. 
 The Trustee shall comply with the
provisions of Trust Indenture Act § 313(b)(2) (as if the Trust Indenture Act were applicable hereto). 
 Section 10.07.
Officers’ Certificate as Evidence. Except as otherwise provided in Section 10.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or
desirable that a matter be proved or established prior to taking or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by an
Officers’ Certificate delivered to the Trustee, and such Officers’ Certificate shall be full warrant to the Trustee for any action taken or omitted by it under the provisions of this Indenture upon the faith thereof. 

Section 10.08. Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a Person that is
eligible pursuant to the Trust Indenture Act (as if the Trust Indenture Act were applicable hereto) to act as such and has a combined capital and surplus of at least $50,000,000. If such Person publishes reports of condition at least annually,
pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. 

  
 93 

 Section 10.09. Resignation or Removal of Trustee. 

(a) The Trustee may at any time resign by giving written notice of such resignation to the Company. Upon receiving such notice
of resignation, the Company shall promptly (x) deliver notice of such resignation to all Holders and (y) appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which
instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment within 30 days after the delivery of such notice of resignation to the
Holders, the resigning Trustee may, upon ten Business Days’ notice to the Company and the Holders, petition any court of competent jurisdiction for the appointment of a successor trustee (at the expense of the Company), or any Holder who has
been a bona fide holder of a Note or Notes for at least six months (or since the date of this Indenture) may, subject to the provisions of Section 9.12, on behalf of himself or herself and all others similarly situated,
petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee. If the Trustee has or shall acquire a conflicting interest
within the meaning of the Trust Indenture Act (as if the Trust Indenture Act were applicable hereto), the Trustee shall either eliminate such interest within ninety (90) days or resign, to the extent and in the manner provided by, and subject
to the provisions of, this Indenture. 
 (b) In case at any time any of the following shall occur: 

(i) the Trustee shall cease to be eligible in accordance with the provisions of Section 10.08 and
shall fail to resign after written request therefor by the Company or by any such Holder, 
 (ii) the Trustee shall become
incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of
rehabilitation, conservation or liquidation, or 
 (iii) the Trustee shall fail to comply with the last sentence of
Section 10.09(a) after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Note or Notes for at least six (6) months; 

then, in either case, the Company may by a Board Resolution remove the Trustee and appoint a successor trustee by written instrument, in duplicate, one copy
of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 9.12, any Holder who has been a bona fide holder of a Note or Notes for at
least six months (or since the date of this Indenture) may, on behalf of himself or herself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee.
Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 

(c) The Required Holders may at any time remove the Trustee and nominate a successor trustee that shall be deemed appointed as
successor trustee. 

  
 94 

 (d) Any resignation or removal of the Trustee and appointment of a successor
trustee pursuant to any of the provisions of this Section 10.09 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 10.10. 

Section 10.10. Acceptance by Successor Trustee. Any successor trustee appointed as provided in
Section 10.09 shall execute, acknowledge and deliver to the Company and to the predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee
shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Trustee
herein; but, nevertheless, on the written request of the Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it hereunder, execute and deliver an instrument transferring to such successor
trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor
trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by such trustee as such, except for funds held in
trust for the benefit of Holders of particular Notes, to secure any amounts then due it hereunder. 
 No successor trustee shall
accept appointment as provided in this Section 10.10 unless at the time of such acceptance such successor trustee shall be eligible under the provisions of Section 10.08. 

Upon acceptance of appointment by a successor trustee as provided in this Section 10.10, each of the Company and the
successor trustee, at the written direction and at the expense of the Company shall deliver or cause to be delivered notice of the succession of such trustee hereunder to the Holders at their addresses as they shall appear on the Note Register. If
the Company fails to deliver such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be delivered at the expense of the Company. 

Section 10.11. Succession by Merger, Etc. Any corporation or other entity into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other entity succeeding to all or substantially all of the
corporate trust business of the Trustee (including the administration of this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto;
provided that in the case of any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee such corporation or other entity shall be eligible under the provisions of
Section 10.08. 
 In case at the time such successor to the Trustee shall succeed to the trusts created by this
Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and
deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an 

  
 95 

 
authenticating agent appointed by such successor trustee may authenticate such Notes either in the name of any predecessor trustee hereunder or in the name of the successor trustee; and in all
such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have; provided, however, that the right to adopt the certificate of
authentication of any predecessor trustee or to authenticate Notes in the name of any predecessor trustee shall apply only to its successor or successors by merger, conversion or consolidation. No resigning or removed Trustee shall have any
liability or responsibility for the action or inaction of any successor Trustee. 
 Section 10.12. Trustee’s
Application for Instructions from the Company. Any application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the
rights of the Holders of the Notes under this Indenture) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be
taken or such omission shall be effective. The Trustee shall not be liable to the Company for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such
application (which date shall not be less than three Business Days after the date any officer that the Company has indicated to the Trustee should receive such application actually receives such application, unless any such officer shall have
consented in writing to any earlier date), unless, prior to taking any such action (or the effective date in the case of any omission), the Trustee shall have received written instructions in accordance with this Indenture in response to such
application specifying the action to be taken or omitted. 
 ARTICLE 11 

Concerning the Holders 

Section 11.01. Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage of
the aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the
Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing, or (b) by the record of
the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Article 12, or (c) by a combination of such instrument or instruments and any such record of such a meeting of
Holders. Whenever the Company or the Trustee solicits the taking of any action by the Holders of the Notes, the Company or the Trustee may, but shall not be required to, fix in advance of such solicitation, a date as the record date for determining
Holders entitled to take such action. The record date if one is selected shall be not more than fifteen days prior to the date of commencement of solicitation of such action. Except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company and the Guarantors. A Holder entitled to take any action hereunder with regard to any particular
Note may do so with regard to all or any part of the principal amount of such Note or by one or more duly appointed agents, each of which may do so pursuant to such appointment with regard to all or any part of such principal amount. Any notice

  
 96 

 
given or action taken by a Holder or its agents with regard to different parts of such principal amount pursuant to this paragraph shall have the same effect as if given or taken by separate
Holders of each such different part. A Holder, including a Depositary that is the Holder of a Global Note, may make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent,
waiver or other action provided in this Indenture to be made, given or taken by Holders, and a Depositary that is the Holder of a Global Note may provide its proxy or proxies to the beneficial owners of interests in any such Global Note through such
Depositary’s standing instructions and customary practices. 
 Section 11.02. Proof of Execution by Holders.
Subject to the provisions of Section 11.01, Section 11.02 and Section 12.05, proof of the execution of any instrument by a Holder or its agent or proxy, the fact and
date of the execution by any Person of any such instrument or writing may be proved (1) by the affidavit of a witness of such execution or by the certificate of any notary public or other officer authorized by law to take acknowledgments of
deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof or (2) in any other manner deemed reasonably sufficient by the Trustee. Where such execution is by or on behalf of any legal
entity other than an individual, such certificate or affidavit shall also constitute proof of the authority of the Person executing the same. 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 that the Trustee deems sufficient. 
 Section 11.03. Who Are Deemed
Absolute Owners. The ownership of Notes shall be proved by the Note Register. The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion Agent and any Note Registrar may deem the Person in whose name a Note shall
be registered upon the Note Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other than the
Company or any Note Registrar) for the purpose of receiving payment of or on account of the principal (including any Fundamental Change Repurchase Price) of, the Redemption Price of (if applicable), and (subject to
Section 2.09) accrued and unpaid interest on such Note, for conversion of such Note, for consenting to any matter, and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion
Agent nor any Note Registrar shall be affected by any notice to the contrary. All such payments or deliveries so made to any Holder for the time being, or upon its order, shall be valid, and, to the extent of the sums or shares of Common Stock so
paid or delivered, effectual to satisfy and discharge the liability for monies payable or shares deliverable upon any such Note. Notwithstanding anything to the contrary in this Indenture or the Notes, following an Event of Default, any holder of a
beneficial interest in a Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such holder’s right to exchange such beneficial
interest for a Note in certificated form in accordance with the provisions of this Indenture. 
 Section 11.04. Record Dates.

 (a) The Company may set a record date for purposes of determining the identity of Holders entitled to make, give or take
any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Indenture to be made, or to vote on or consent to any action authorized or permitted to be taken by Holders;

  
 97 

 
provided that the Company may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or
direction referred to in clause (b) below. Unless otherwise specified, if not set by the Company prior to the first solicitation of a Holder made by any Person in respect of any such action, or in the case of any such vote, prior to such vote,
any such record date shall be the later of 30 days prior to the first solicitation of such consent or vote or the date of the most recent list of Holders furnished to the Trustee prior to such solicitation or vote. If any record date is set pursuant
to this clause (a), the Holders on such record date, and only such Holders, shall be entitled to make, give or take such request, demand, authorization, direction, notice, consent, waiver or other action (including revocation of any action), whether
or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless made, given or taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Notes, or
each affected Holder, as applicable, on such record date. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Trustee in writing and to each Holder in the manner set forth in Section 21.03. 

(b) The Trustee may set any day as a record date for the purpose of determining the Holders entitled to join in the giving or
making of (1) any notice of default under Section 9.10 (2) any declaration of acceleration referred to in Section 9.02, (3) any direction referred to in Section 9.09
or (4) any request to pursue a remedy as permitted in Section 9.09. If any record date is set pursuant to this paragraph, the Holders on such record date, and no other Holders, shall be entitled to join in such notice,
declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless made, given or taken on or prior to the applicable Expiration Date by Holders of
the requisite principal amount of Notes or each affected Holder, as applicable, on such record date. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record
date, the proposed action by Holders and the applicable Expiration Date to be given to the Company and to each Holder in the manner set forth in Section 21.03. 

(c) The Company may fix a record date for the purpose of determining the Persons who are beneficial owners of interests in any
Global Note held by a Depositary entitled under the procedures of such Depositary, if any, to make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action
provided in this Indenture to be made, given or taken by Holders; provided that if such a record date is fixed, only the beneficial owners of interests in such Global Note on such record date or their duly appointed proxy or proxies shall be
entitled to make, give or take such request, demand, authorization, direction, notice, consent, waiver or other action, whether or not such beneficial owners remain beneficial owners of interests in such Global Note after such record date. No such
request, demand, authorization, direction, notice, consent, waiver or other action shall be effective hereunder unless made, given or taken on or prior to the applicable Expiration Date. 

  
 98 

 (d) With respect to any record date set pursuant to this
Section 11.04, the party hereto that sets such record date may designate any day as the “Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such
change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Notes in the manner set forth in Section 21.03, on or prior to both the
existing and the new Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section 11.04, the party hereto which set such record date shall be deemed to have initially
designated the 90th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this clause (d). 

(e) [Intentionally Omitted.] 

Section 11.05. Revocation of Consents; Future Holders Bound. At any time prior to (but not after) the evidencing to the
Trustee, as provided in Section 11.01, of the taking of any action by the Holders of the percentage of the aggregate principal amount of the Notes specified in this Indenture in connection with such action, any Holder of a
Note that is shown by the evidence to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in
Section 21.03, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners of
such Note and of any Notes issued in exchange or substitution therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or
upon registration of transfer thereof. 
 Section 11.06. Outstanding Notes. In determining whether the Holders of the
requisite principal amount of Notes have concurred in any direction, waiver or consent, Notes beneficially owned by the Company, or by any Subsidiary of the Company, 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 that a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. Notes so owned which have been pledged
in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right to deliver any such direction, waiver or consent with respect to the Notes and that the pledgee is not the Company or a
Subsidiary of the Company.

(c) Without the consent of each Holder of an outstanding Note affected, no such supplemental indenture, amendment or waiver
shall: 
 (i) reduce the principal of any Note or extend the fixed maturity of any Note; 

(ii) postpone or delay any date fixed for, or reduce or waive, any scheduled installment of principal or any payment of
interest, fees or other amounts due to the Holders (or any of them) hereunder or under any other Indenture Document; 
 (iii)
change or have the effect of changing the pro rata treatment of any payments with respect to the Notes provided that, for the avoidance of doubt, the definition of “ABL Obligations Cap” set forth in the Intercreditor Agreement, may be
amended at any time with the consent of the Required Holders; 

  
 101 

 (iv) change the percentage of the outstanding principal amount of the Notes
which will be required for the Holders or any of them to take any action hereunder;

 (viii)

the covenants, definitions or otherwise;

that stated in the Note; 
 (x) [Intentionally Omitted]; 

(xi) impair the right of any Holder to receive payment of the principal and interest on such Holder’s Notes on or after
the due dates therefor or to institute suit for enforcement of any payment on or with respect to the Holder’s Notes. 

(d) Upon the written request of the Company, and upon the filing with the Trustee of evidence of the consent of Holders as
aforesaid and subject to Section 13.05, the Trustee shall join with the Company in the execution of such supplemental indenture, amendment or waiver unless such supplemental indenture, amendment or waiver adversely affects
the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture, amendment or waiver. 

(e) Notwithstanding any other provisions set forth herein, the consent of the Supermajority Holders is required to release all
or substantially all of the Collateral except as otherwise may be provided or permitted under this Indenture or the other Indenture Documents. 

(f) Holders do not need, under this Section 13.02, to approve the particular form of any proposed
supplemental indenture, amendment or waiver. It shall be sufficient if such Holders approve the substance thereof. After any such supplemental indenture, amendment or waiver becomes effective, the Company shall send to the Holders a notice briefly
describing such supplemental indenture, amendment or waiver. However, the failure to give such notice to all the Holders, or any defect in the notice, will not impair or affect the validity of the supplemental indenture, amendment or waiver. 

  
 102 

 Section 13.03. Effect of Supplemental Indentures. Upon the execution of
any supplemental indenture, amendment or waiver pursuant to the provisions of this Article 13, this Indenture and any other Indenture Documents shall be and be deemed to be modified and amended in accordance therewith and the respective
rights, limitation of rights, obligations, duties and immunities under this Indenture and the other Indenture Documents of the Trustee, the Company and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all
respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture, amendment or waiver shall be and be deemed to be part of the terms and conditions of this Indenture and the other Indenture Documents

any supplemental indenture, amendment or waiver pursuant to the provisions of this Article 13 may, at the Company’s expense, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture,
amendment or waiver. If the Company or the Trustee shall so determine, new Notes so modified as to conform, in the opinion of the Trustee, to any modification of this Indenture and the other Indenture Documents contained in any such supplemental
indenture, amendment or waiver may, at the Company’s expense, be prepared and executed by the Company, authenticated by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section 21.09)
upon receipt of an Officers’ Certificate, an Opinion of Counsel, and a Company Order and delivered in exchange for the Notes then outstanding, upon surrender of such Notes then outstanding.

required by Section 21.05, the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture, amendment or waiver executed pursuant hereto complies with
the requirements of this Article 13 and is permitted or authorized by this Indenture and any Opinion of Counsel shall state that the supplemental indenture, amendment or waiver is the legal, valid and binding obligation of the Company,
enforceable against it in accordance with its terms.

 ARTICLE 16 

Notice of Specified Corporate Events 

Section 16.01. Certain Distributions. If, prior to the close of business on the Business Day immediately preceding the
Maturity Date, the Company elects to: 
 (a) issue to all or substantially all holders of the Common Stock any rights,
options or warrants entitling them, for a period of not more than 60 calendar days after the announcement date of such issuance, 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 issuance; or 

(b) distribute to all or substantially all holders of the Common Stock the Company’s assets, securities or rights to
purchase securities of the Company, which distribution has a per share value, as reasonably determined by the Board of Directors, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day preceding the date of announcement
for such distribution,

Conversion Agent (if other than the Trustee) (x) as promptly as practicable following the date the Company publicly announces such transaction but in no event less than 40 Scheduled Trading Days prior to the anticipated effective date of such
transaction or (y) if the Company does not have knowledge of such transaction at least 40 Scheduled Trading Days prior to the anticipated effective date of such transaction, within one Business Day of the date upon which the Company receives
notice, or otherwise becomes aware, of such transaction, but in no event later than the actual effective date of such transaction.

 ARTICLE 17 

Conversion of Notes 

Section 17.01. Conversion Privilege. Subject to and upon compliance with the provisions of this Article 17, each
Holder of a Note shall have the right, at such Holder’s option, at any time prior to the close of business on the second Business Day immediately preceding the Maturity Date, to convert all or a portion of such Note, at an initial conversion
rate of 173.91304 shares of Common Stock (subject to adjustment as provided in this Article 17 and in the Registration Rights Agreement, the “Conversion Rate”) per $1,000 principal amount of Notes (subject to, and in
accordance with, the settlement provisions of Section 17.02, the “Conversion Obligation”) into shares of Common Stock or, to the extent set forth in the Note Purchase Agreement, warrants to purchase shares
of Common Stock (“Warrants”). The Conversion Rate shall be increased by 3.00% for each $1,000 principal amount of Notes converted or redeemed (as applicable) at a time when a Registration Default (as defined under the Registration
Rights Agreement) has occurred and is continuing; provided, however, that (i) the foregoing adjustment shall not be applied more than once to the same $1,000 principal amount of Notes and (ii) if a Registration Default (as defined under
the Registration Rights Agreement) occurs after a Holder has converted its Notes into shares of Common Stock, such Holder shall not be entitled to any such additional compensation with respect to such Common Stock. 

Section 17.02. Conversion Procedure; Settlement Method. 

(a) Each Note shall be convertible at the office of the Conversion Agent. 

(b) Before any Holder of a Note shall be entitled to convert a Note as set forth in this Article 17, such Holder shall:

 (i) in the case of a Global Note, (1) comply with the procedures of the Depositary in effect at that time and, if
required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 17.02(h) and (2) if required, pay all transfer or similar Taxes, if any, as
set forth in Section 17.02(f); and 
 (ii) in the case of a Physical Note (1) complete,
manually sign and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and state in writing
therein the principal amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to
be registered, (2) with respect to any Permitted Holder, complete, manually sign and deliver the warrant election form attached as Exhibit A to the Note Purchase Agreement (failure to deliver such election shall be deemed to constitute an
election to receive shares of Common Stock), (3) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (4) if required,
pay all transfer or similar Taxes, if any, as set forth in Section 17.02(f) and (5) if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth
in Section 17.02(h). 

  
 107 

 The Trustee (and if different, the Conversion Agent) shall notify the Company of any
conversion pursuant to this Article 17 on the Conversion Date for such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase
Notice to the Company in respect of such Notes and has not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 18.03. If a Holder submits its Notes for required repurchase upon a
Fundamental Change, the Holder’s right to withdraw the Fundamental Change Repurchase Notice and convert the Notes that are subject to repurchase will terminate at the close of business on the Business Day immediately preceding the relevant
Fundamental Change Repurchase Date. 
 If more than one Note shall be surrendered for conversion at one time by the same Holder, the
Conversion Obligation with respect to such Notes shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted hereby) so surrendered. 

(c) A Note shall be deemed to have been converted immediately prior to the close of business on the date (the
“Conversion Date”) that the Holder has complied with the requirements set forth in Section 17.02(b) above. Except as set forth in Section 17.03(b) and
Section 17.07(a), the Company shall pay or deliver, as the case may be, the consideration due in respect of the Conversion Obligation (A) in the case of Physical Settlement, on the second Business Day immediately
following the relevant Conversion Date, unless such Conversion Date occurs on or after the Regular Record Date immediately preceding the Maturity Date, in which case the Company shall make such delivery (and payment, if applicable) on the Maturity
Date or (B) in the case of any other Settlement Method, on the second Business Day immediately following the last Trading Day of the Observation Period. If any shares of Common Stock or, in the case of Permitted Holders, Warrants are due to
converting Holders, the Company shall issue or cause to be issued, and deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the full number of,
as applicable, shares of Common Stock or Warrants to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation, and cash in lieu of any fractional shares of Common Stock or Warrants. 

(d) A Holder may convert fewer than all of such Holder’s Notes so long as the Notes converted are a multiple of $1,000 in
principal amount. In case any Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so surrendered 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 Section 17.02(f), 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. 
 (e)
Upon the conversion of an interest in a Global Note, the Trustee, or the 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. The Company shall notify
the Trustee in writing of any conversion of Notes effected through any Conversion Agent other than the Trustee. 

  
 108 

 (f) If a Holder submits a Note for conversion, the Company shall pay any
documentary, stamp or similar issue or transfer Tax due on the issue of, as applicable, any shares of Common Stock or Warrants upon conversion, unless the Tax is due because the Holder requests such shares or any portion of Notes not converted to be
issued in a name other than the Holder’s name, in which case the Holder shall pay that Tax. The Conversion Agent shall not deliver the certificates representing or effect a book-entry transfer through the Depositary for the shares of Common
Stock or Warrants being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay, or the Holder has established to the Company’s satisfaction the prior payment of, any Tax that is due by such Holder
in accordance with the immediately preceding sentence. 
 (g) Except as provided in Section 17.04,
no adjustment shall be made for dividends on any shares of Common Stock or Warrants issued upon the conversion of any Note as provided in this Article 17. 

(h) Upon conversion, a Holder shall not receive any separate cash payment for accrued and unpaid interest, if any, except as
set forth below in this clause (h), and the Company shall not adjust the Conversion Rate to account for accrued and unpaid interest on the Notes. The Company’s settlement of the full Conversion Obligation shall be deemed to satisfy in full its
obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date
shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular Record Date, Holders of such Notes as of the close of business on
such Regular Record Date will receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any
Regular Record Date to the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted; provided that no such payment shall be required
(1) for conversions following the Regular Record Date immediately preceding the Maturity Date and before the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date; (2) if the Company has specified a
Redemption Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date; (3) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the
corresponding Interest Payment Date; or (4) to the extent of any Defaulted Amounts, if any Defaulted Amounts exists at the time of conversion with respect to such Note. Therefore, for the avoidance of doubt, all Holders of record on the Regular
Record Date immediately preceding the Maturity Date or any Redemption Date shall receive the full interest payment due on the Maturity Date or such Redemption Date, as applicable, regardless of whether their Notes have been converted following such
Regular Record Date. 

  
 109 

 (i) Each conversion shall be deemed to have been effected immediately prior
to the close of business on the relevant Conversion Date; provided, however, that the Person in whose name, as applicable, the shares of Common Stock or Warrants shall be issuable upon conversion shall be treated as a stockholder of
record as of the close of business on the relevant Conversion Date (in the case of Physical Settlement) or as of the close of business on the last Trading Day of the relevant Observation Period (in the case of Combination Settlement). Upon a
conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion as of immediately prior to the close of business on the related Conversion Date. 

(j) The Company shall not issue fractional shares or Warrants upon conversion of Notes. If multiple Notes shall be surrendered
for conversion at one time by the same Holder, the number of full shares or Warrants which shall be issuable upon conversion (and the number of fractional shares or Warrants, if any, for which cash shall be delivered) shall be computed on the basis
of the aggregate Principal Amount of the Notes (or specified portions thereof to the extent permitted hereby) so surrendered. If any fractional share or Warrants would be issuable upon the conversion of any Notes, the Company shall make payment of
an amount in cash in lieu of any fractional share of Common Stock or Warrants otherwise issuable upon conversion based on the Daily VWAP of the Common Stock on the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily
VWAP on the last Trading Day of the relevant Observation Period (in the case of Combination Settlement). For each Note surrendered for conversion, if the Company has elected to satisfy its conversion obligation through Combination Settlement, the
full number of shares that shall be issued upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the applicable Observation Period and any fractional share remaining after such computation shall be paid
in cash. The current market value of a fractional share shall be determined (calculated to the nearest 1/1000th of a share) by multiplying the Last Reported Sale Price of the Common Stock on the relevant Conversion Date by such fractional share and
rounding the product to the nearest whole cent. 
 (k) Subject to this Section 17.02,
Section 17.03(b), Section 17.07(a) and Section 17.12, the Company may settle the Conversion Obligation in cash (“Cash Settlement”), shares of Common Stock
(or, if applicable, Warrants), together with cash, if applicable, in lieu of delivering any fractional share of Common Stock (or, if applicable, Warrants) in accordance therewith (“Physical Settlement”) or a combination of cash and
shares of Common Stock (or, if applicable, Warrants), together with cash, if applicable, in lieu of delivering any fractional share of Common Stock “Combination Settlement”), at its election, as set forth in this
Section 17.02(k). 
 (i) All conversions for which the relevant Conversion Date occurs on or after
the 25th Scheduled Trading Day prior to the Maturity Date, and all conversions for which the relevant Conversion Date occurs after the Company’s issuance of a Redemption Notice with respect to the Notes and prior to the related Redemption Date,
shall be settled using the same Settlement Method. Except for any conversions for which the relevant Conversion Date occurs after the Company’s issuance of a Redemption Notice with respect to the Notes but prior to

  
 110 

 
the related Redemption Date or any conversions for which the relevant Conversion Date occurs on or after the 25th Scheduled Trading Day prior to the Maturity Date, the Company shall use the same
Settlement Method for the Conversion Obligations for all conversions with the same Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to the Conversion Obligations for Conversions with
different Conversion Dates. 
 (ii) If, in respect of any Conversion Date, the Company elects a Settlement Method in respect
of such Conversion Date, the Company shall deliver or cause delivery of a notice (the “Settlement Notice”) of the relevant Settlement Method to converting Holders and the Conversion Agent (and the Trustee if not the Conversion
Agent) no later than the close of business on the Trading Day immediately following the relevant Conversion Date (or, if such Conversion Date occurs (x) after the date of issuance of a Redemption Notice with respect to the Notes and prior to
the related Redemption Date, no later than the date of issuance of such Redemption Notice or (y) on or after June 15, 2023, no later than June 15, 2023). Such Settlement Notice shall specify the relevant Settlement Method and in the
case of an election of Combination Settlement, the Specified Dollar Amount to be settled in cash and in shares of Common Stock (or, if applicable, Warrants), respectively. If the Company does not elect a Settlement Method for any Conversion Date
prior to the deadline set forth in the second preceding sentence, the Company shall no longer have the right to elect a Settlement Method for such Conversion Date and the Company shall be deemed to have elected Combination Settlement for such
Conversion Date. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount per $1,000 principal amount of Notes in such Settlement Notice, the
Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be $1,000. The Company shall have the right to irrevocably elect a Settlement Method and Specified Dollar Amount for all subsequent Conversion Dates by delivering the
Settlement Notice to all Holders of the Notes, the Trustee and the Conversion Agent and issuing a press release containing information regarding its election of Settlement Method and Specified Dollar Amount and expressly stating such election is
irrevocable and making such information available on its website. Following such an irrevocable Settlement Notice, the Company will not have the right to change the Selection Method or Specified Dollar Amount. 

(iii) The cash, shares of Common Stock or combination of cash and shares of Common Stock in respect of any conversion of Notes
(the “Settlement Amount”) shall be computed by the Company as follows: 
 (A) if the Company elects (or is
deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall deliver to the converting Holder in respect of each $1,000 principal amount of Notes being converted a number of
shares of Common Stock (or, if applicable, Warrants) equal to the Conversion Rate in effect on the Conversion Date; 

  
 111 

 (B) if the Company elects (or is deemed to have elected) to satisfy its
Conversion Obligation in respect of such conversion by Cash Settlement, the Company shall pay to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion
Values for each of the 20 consecutive Trading Days during the related Observation Period; and 
 (C) if the Company elects
(or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, to the converting Holder in respect of each $1,000 principal amount of
Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 20 consecutive Trading Days during the related Observation Period. 

(iv) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the
Company promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering any
fractional share of Common Stock, the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) in writing of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable
in lieu of delivering fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination. 

(v) Notwithstanding anything to the contrary in this Indenture, if at any time prior to the Share Increase Approval (as defined
in the Note Purchase Agreement and referred to in Section 17.08(a)), Additional Shares are issuable on the conversion of the then outstanding Notes in connection with a Make-Whole Fundamental Change, the Company shall
settle its Conversion Obligation with respect to such Additional Shares by Cash Settlement, to the extent that the Company does not then have a sufficient number of shares authorized and reserved for issuance upon conversion of Notes under the
Company’s Governing Documents to issue all shares of Common Stock (including any Additional Shares) that may be issuable upon conversion of all Notes then outstanding. 

Section 17.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental
Changes. 
 (a) If the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date and a Holder
elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under the circumstances described below, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares
of Common Stock (the “Additional Shares”), as described below. A conversion of Notes shall be deemed for these purposes 

  
 112 

 
to be “in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent during the period from, and including, the
Effective Date of the Make-Whole Fundamental Change up to, and including, the Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental
Change but for the proviso in clause (b) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change) (such period, the “Make-Whole Fundamental Change
Period”). 
 (b) If, at the effective time of a Make-Whole Fundamental Change described in clause (b) of the
definition of Fundamental Change, the Reference Property following such Make-Whole Fundamental Change is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion
Obligation shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the Conversion Rate (including any adjustment for Additional
Shares), multiplied by such Stock Price. In such event, the Conversion Obligation shall be paid to Holders in cash on the third Business Day following the Conversion Date. The Company shall notify the Holders of Notes, the Trustee and the
Conversion Agent (if other than the Trustee) of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date. 

(c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference
to the table set forth in Section 17.03(e) below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the “Stock
Price”) paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change. If the holders of the Common Stock receive in exchange for their Common Stock only cash in a Make-Whole Fundamental Change described in
clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period
ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change. 

(d) The Stock Prices set forth in the column headings of the table set forth in Section 17.03(e)
below shall be adjusted as of any date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the
numerator of which is the Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table set
forth in Section 17.03(e) below shall be adjusted in the same manner and at the same time as the Conversion Rate is adjusted as set forth in Section 17.04. 

  
 113 

 (e) The following table sets forth the number of Additional Shares of Common
Stock by which the Conversion Rate shall be increased per $1,000 principal amount of Notes pursuant to this Section 17.03 for each Stock Price and Effective Date set forth below:

 The exact Stock Prices and Effective Dates may not be set forth in the table above, in which case: 

(i) if the Stock Price is between two Stock Prices in the table above or the Effective Date is between two Effective Dates in
such table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the earlier and later Effective Dates, as applicable, based
on a 365-day year; 
 (ii) if the Stock Price is greater than $25.00 per share
(subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate; and 

(iii) if the Stock Price is less than $4.00 per share (subject to adjustment in the same manner as the Stock Prices set forth
in the column headings of the table above pursuant to subsection (d) above), no further Additional Shares shall be added to the Conversion Rate. 

(f) Nothing in this Section 17.03 shall prevent an adjustment to the Conversion Rate pursuant to
Section 17.04 in respect of a Make-Whole Fundamental Change. 
 Section 17.04. Adjustment of Conversion
Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes 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 the Common Stock and solely as a result of holding the Notes, in any of the transactions
described in this Section 17.04, 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 Company issues shares of Common Stock as a dividend or distribution on shares of
the Common Stock, or if the Company effects a share split or share combination of the Common Stock, the Conversion Rate shall be adjusted based on the following formula: 

  
 115 

 

 
 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; 
 CR’ = the Conversion Rate in effect immediately
after the open of business on such Ex-Dividend Date or Effective Date; 
 OS0 = the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date; and 

OS’ = the number of shares of Common Stock outstanding immediately after, and solely as a result of, giving effect to such dividend, distribution, share
split or share combination. 
 Any adjustment made under this Section 17.04(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 17.04(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 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. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the
Conversion Rate, no adjustment to the Applicable Rate will be made (other than (i) as a result of a reverse share split or share combination or (ii) with respect to the Company’s right to readjust the Conversion Rate as described in
the immediately preceding sentence). 
 (b) If the Company issues to all or substantially all holders of the Common Stock any
rights, options or warrants entitling them, for a period of not more than 60 calendar days after the announcement date of such issuance, 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 issuance, the Conversion Rate shall be increased based on
the following formula: 
  
 

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

  
 116 

 CR’ = 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; 
 X = the total number of shares of
Common Stock issuable 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 issuance of such rights, options or warrants. 
 Any increase in the Conversion Rate made under this
Section 17.04(b) shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the open of business on the
Ex-Dividend Date for such issuance. To the extent that shares of the Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be decreased, effective
as of such date of expiration, to the Conversion Rate that would then be in effect had the increase with respect to the issuance 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 issued, the Conversion Rate shall be decreased, effective as of the date of the Board of Directors determines not to issue such rights, options or warrants, to the Conversion Rate
that would then be in effect if such Ex-Dividend Date for such issuance had not occurred. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the Conversion
Rate, no adjustment to the Conversion Rate will be made (other than with respect to the Company’s right to readjust the Conversion Rate as described in the two immediately preceding sentences). 

In determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at a price less than such
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 for such issuance, and in determining the aggregate
offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, with the value of such
consideration, if other than cash, to be determined by the Board of Directors. 
 (c) If the Company distributes shares of
its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire the Company’s Capital Stock or other securities, to all or substantially all holders of the Common Stock,
excluding (i) dividends, distributions or issuances as to which an adjustment was effected pursuant to Section 17.04(a) or Section 17.04(b), (ii) dividends or distributions paid exclusively in
cash as to which the provisions set forth in Section 17.04(d) shall apply, and (iii) Spin-Offs as to which the provisions set forth below in this Section 17.04(c) shall apply (any of such
shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities, the “Distributed Property”), then the Conversion Rate shall be increased based
on the following formula: 

  
 117 

 

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

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

SP0 = 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 Ex-Dividend Date for such distribution; and 

FMV = the fair market value (as determined by the Board of Directors) of the Distributed Property 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 17.04(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, effective as of the date the Board of Directors announces its decision not to make or pay such distribution, to 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 of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock receive the Distributed Property, the amount and kind of Distributed Property 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. If the Board of Directors determines the
“FMV” (as defined above) of any distribution for purposes of this Section 17.04(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in
such market over the same period used in computing the average of 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 Ex-Dividend Date for such distribution. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate will be made
(other than with respect to the Company’s right to readjust the Applicable Conversion Rate as described in the second sentence of this paragraph). 

With respect to an adjustment pursuant to this Section 17.04(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 interest, of or relating to a Subsidiary or other business unit of the Company, 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: 

  
 118 

 

 
 where, 
 CR0 = the Conversion Rate in effect immediately prior to the end of the Valuation Period; 
 CR’ = the
Conversion Rate in effect immediately after the end of the Valuation Period; 
 FMV0 = the average of
the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock (determined by reference to the definition of Last Reported Sale Price as set forth
in Section 1.01 as if references therein to Common Stock were to such Capital Stock or similar equity interest) 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 Last Reported Sale Prices of the Common Stock over the Valuation Period. 

The increase to the Conversion Rate under the preceding paragraph shall become effective immediately after the open of business on the last
Trading Day of the Valuation Period; provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during the Valuation Period, references in the preceding
paragraph to a “10 consecutive Trading Day period” shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date of such Spin-Off to, but excluding, the Conversion Date in determining the Conversion Rate and the effective time of any adjustment thereto and (y) in respect of any conversion of Notes for which Cash Settlement or
Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the Valuation Period, references in the preceding paragraph with respect to 10 consecutive Trading Days shall
be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date of such Spin-Off to, but excluding, such
Trading Day in determining the conversion rate as of such Trading Day. 
 For purposes of this Section 17.04(c)
(and subject in all respect to Section 17.11), rights, options or warrants distributed by the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital
Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such
shares of the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this
Section 17.04(c) (and no adjustment to the Conversion Rate under this Section 17.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options

  
 119 

 
or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 17.04(c).
If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to
purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with
respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event of
any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other such event (of the type described in the immediately preceding sentence) with respect thereto that was deemed to effect a distribution of rights,
options or warrants, in each case for which an adjustment to the Conversion Rate under this Section 17.04(c) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or
purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again
be readjusted, effective as of the date of such final redemption or purchase, to give effect to such distribution, deemed distribution or Trigger Event or other such event, as the case may be, as though it were a cash distribution, equal to the per
share redemption or purchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the
date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted, effective as of such
expiration or termination date, as if such rights, options and warrants had not been issued. 
 For purposes of
Section 17.04(a), Section 17.04(b) and this Section 17.04(c), if any dividend or distribution to which this Section 17.04(c) is applicable (other
than a Spin-Off) has the same Record Date as one or both of: 
 (A) a dividend or
distribution of shares of Common Stock to which Section 17.04(a) is applicable (the “Clause A Distribution”); or 

(B) a dividend or distribution of rights, options or warrants to which Section 17.04(b) is
applicable (the “Clause B Distribution”), 
 then, in either case, (1) such dividend or distribution, other than the Clause A
Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 17.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment
required by this Section 17.04(c) with respect to such Clause C Distribution shall first be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C
Distribution and any Conversion Rate adjustment required by Section 17.04(a) and Section 17.04(b) with respect thereto shall then be made (as if the Conversion Rate adjustment required by this
Section 17.04(c) with respect to such Clause C Distribution had been made immediately prior to the open of business on the Ex-Dividend Date for the Clause A Distribution and the
Clause B Distribution), except that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the
Ex-

  
 120 

 
Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding
immediately prior to the open of business on such Ex-Dividend Date or Effective Date” within the meaning of Section 17.04(a) or “outstanding immediately prior to the open of
business on such Ex-Dividend Date” within the meaning of Section 17.04(b). 

(d) If any cash dividend or distribution is made to all or substantially all holders of the Common Stock, the Conversion Rate
shall be increased based on the following formula: 
  
 

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

CR’ = the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such
dividend or distribution; 
 SP0 = the Last Reported Sale Price 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 the Company distributes to all or substantially all holders of the Common Stock. 
 Any increase in the Conversion Rate pursuant to this
Section 17.04(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 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 of a Note shall receive, for each $1,000 principal amount of Notes, 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 Common Stock equal to the Conversion Rate on the Ex-Dividend Date for such cash dividend or distribution. For the avoidance of doubt, if the application of the foregoing formula would
result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate will be made (other than with respect to the Company’s right to readjust the Conversion Rate as described in the second sentence of this paragraph). 

(e) If the Company or any of its Subsidiaries make a payment in respect of a tender or exchange offer for the Common Stock
(other than an odd-lot tender offer), to the extent that the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the average of the Last Reported Sale Prices
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: 

  
 121 

 

 
 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; 
 CR’ = 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 Board of Directors) 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); 
 OS’ = 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 

SP’ = the average of the Last Reported Sale Prices 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 this
Section 17.04(e) shall become effective at the open 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 (x) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the 10 Trading Days
immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references in this Section 17.04(e) with respect to “10” or “10th” shall be
deemed replaced with such lesser number of Trading Days as have elapsed during the period from, and including, the Trading Day after the expiration date of such tender or exchange offer to, but excluding, such Trading Day in determining the
Conversion Rate as of such Trading Day and (y) in respect of any conversion of Notes for which Physical Settlement is applicable, 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 in this Section 17.04(e) with respect to “10” or “10th” 

  
 122 

 
shall be deemed replaced with such lesser number of Trading Days as have elapsed during the period from, and including, the Trading Day after the date that such tender or exchange offer expires
and to, but excluding, the Conversion Date in determining the Conversion Rate and the effective time of any adjustment thereto. 
 If the
Company or any Subsidiary is obligated to purchase shares of Common Stock pursuant to any such tender offer or exchange offer, but the Company or such Subsidiary is ultimately prevented by Applicable Law from effecting all or any portion of such
purchases or all such purchases are rescinded, the Conversion Rate shall immediately be readjusted, effective as of the date of the Board of Directors determines not to issue such rights, options or warrants, to the Conversion Rate that would then
be in effect if such tender offer or exchange offer had not been made or had been made only in respect of the purchases that had been effected. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the
Conversion Rate, no adjustment to the Conversion Rate will be made (other than with respect to the Company’s right to readjust the Conversion Rate as described in the immediately preceding sentence). 

(f) Notwithstanding this Section 17.04 or any other provision of this Indenture or the Notes, if a
Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and either (i) a Holder has converted its Notes for Physical Settlement on a Conversion Date that is on or after such Ex-Dividend Date and on or prior to the related Record Date and such Holder would be treated as the record holder of the shares of Common Stock as of the related Conversion Date as described under
Section 17.02(i) based on an adjusted Conversion Rate otherwise becoming effective on such Ex-Dividend Date or (ii) a Holder has converted its notes for Combination Settlement
with the last Trading Day of the related Observation Period ending on or after such Ex-Dividend Date and on or prior to the related Record Date and such Holder would be treated as the record holder of the
shares of Common Stock as of the last trading day of such Observation Period as described in Section 17.02(i) based on an adjusted Conversion Rate for such Ex-Dividend Date, then, in
the case of (i) or (ii), notwithstanding the Conversion Rate adjustment provisions in this Section 17.04, the Conversion Rate adjustment otherwise becoming effective on such
Ex-Dividend Date shall 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
Company shall not adjust the Conversion Rate for the issuance or acquisition of shares of the Common Stock or any securities convertible into or exchangeable for shares of the Common Stock or the right to purchase shares of the 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 17.04, and to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, the Company from time to time
may increase the Conversion Rate by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, to the extent permitted

  
 123 

 
by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, the Company may (but is not required to) increase the
Conversion Rate to avoid or diminish any income Tax to holders of Common Stock or rights to purchase Common Stock in connection with a dividend or distribution of shares of Common Stock (or rights to acquire shares of Common Stock) or similar event.
Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall deliver to the Holder of each Note at its last address appearing on the Note Register a notice of the increase at least 15 days prior to
the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect. 

(i) Notwithstanding anything to the contrary in this Article 17, the Conversion Rate shall not be adjusted: 

(i) 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 Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan; 

(ii) 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 plan or program of or assumed by the Company or any of the Company’s Subsidiaries; 

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

(iv) upon the repurchase of any shares of Common Stock pursuant to an odd lot tender offer or an open-market share repurchase
program or other buy-back transaction that is not a tender offer or exchange offer of the nature described in Section 17.04(e); 

(v) solely for a change in the par value of the Common Stock; and 

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

(j) All calculations and other determinations under this Article 17 shall be made by the Company and shall be made to
the nearest one-ten thousandth (1/10,000th) of a share. 
 (k) Whenever the
Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent if not the Trustee) an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a
brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion

  
 124 

 
Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of
such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall deliver such notice of such adjustment of the Conversion Rate to each Holder at its last address
appearing on the Note Register. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 

(l) For purposes of this Section 17.04, the number of shares of Common Stock at any time outstanding
shall not include shares of Common Stock held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares of Common
Stock issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 
 (m) For purposes
solely of this Section 17.04, the number of shares of Common Stock which the Holder of any Note would have been entitled to receive had such Note been converted in full at any time or into which any Note was converted at
any time shall be determined assuming such Note was convertible in full at such time, although such Note may not be convertible in full at such time pursuant to Section 17.12. 

(n) Irrespective of any adjustment in the Conversion Rate applicable or the amount or kind of shares into which the Notes are
convertible, Notes theretofore or thereafter issued may continue to express the same Conversion Rate initially applicable or amount or kind of shares initially issuable upon conversion of the Notes pursuant to this Indenture. 

Section 17.05. Adjustments of Prices. Whenever any provision of this Indenture requires the Company to calculate the Last
Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including an Observation Period, a Valuation Period and the period for determining the Stock Price for purposes of a
Make-Whole Fundamental Change), the Board of Directors shall make appropriate adjustments to each that it determines to be appropriate to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment
to the Conversion Rate (or changes to the market price per share of Common Stock resulting from any such event) where the Ex-Dividend Date, Effective Date or expiration date, as the case may be, of the event
occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated, without duplication of any adjustment made pursuant to
Section 17.04. The Company will likewise make appropriate adjustments where a Conversion Rate adjustment otherwise required to be made pursuant to the provisions of Sections 17.04(a) through 17.04(e) is not
made in accordance with the provisions described under Section 17.04 that permit or require participation by Holders in a transaction in lieu of such Conversion Rate adjustment. 

Section 17.06. Shares to Be Fully Paid. The Company shall provide, free from preemptive rights, out of its authorized but
unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are surrendered for conversion (assuming delivery of the maximum number of Additional Shares
pursuant to Section 17.03 and that at the time of computation of such number of shares, all such Notes would be converted by a single Holder and that Physical Settlement were applicable). 

  
 125 

 Section 17.07. Effect of Recapitalizations, Reclassifications and Changes of the
Common Stock. 
 (a) In the case of: 

(i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a share split or
share combination), 
 (ii) any consolidation, merger, combination or similar transaction involving the Company, 

(iii) any sale, lease or other transfer to a third party of the consolidated assets of the Company and the Company’s
Subsidiaries substantially as an entirety or 
 (iv) any statutory share exchange, 

in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including
cash or any combination thereof) (any such event, a “Merger Event”), then, at the effective time of such Merger Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to convert such
principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate
immediately prior to such Merger Event would have owned or been entitled to receive (the “Reference Property,” with each “unit of Reference Property” meaning the kind and amount of Reference Property that a holder
of one share of Common Stock would have owned or been entitled to receive) upon such Merger Event and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with
the Trustee a supplemental indenture permitted under Section 13.01(g) providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however, that at and after the effective
time of the Merger Event (A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with Section 17.02
and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 17.02 shall continue to be payable in cash, (II) any shares of Common Stock that the Company would have been required
to deliver upon conversion of the Notes in accordance with Section 17.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have owned or
been entitled to receive upon such Merger Event and (III) the Daily VWAP will be calculated based on the value of the amount and kind of Reference Property that a holder of one share of Common Stock would have owned or been entitled to receive
upon such Merger Event. 

  
 126 

 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 (i) the Reference Property into which the Notes will be convertible shall be deemed to be (x) the weighted
average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election or (y) if no holders of Common Stock affirmatively make such an election, the types and amounts of consideration
actually received by the holders of Common Stock, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common
Stock. The Company 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. If the holders of the Common Stock receive only cash in such
Merger Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of such Merger Event (A) the consideration due upon conversion of each $1,000 principal amount of Notes shall be solely cash in an
amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 17.03), multiplied by the price paid per share of Common Stock in such Merger
Event and (B) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the third Business Day immediately following the relevant Conversion Date. 

Such supplemental indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that
shall be as nearly equivalent as is possible to the adjustments provided for in this Article 17. If, in the case of any Merger Event, the Reference Property includes shares of stock, securities or other property or assets (including cash or
any combination thereof) of a Person other than the successor or purchasing corporation, 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 of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including the provisions providing for the purchase rights set forth in Article 18. 

(b) When the Company executes a supplemental indenture pursuant to subsection (a) of this
Section 17.07, the Company shall promptly file with the Trustee, and the Conversion Agent (if other than the Trustee) an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of cash,
securities or property or asset that will comprise a unit of Reference Property after any such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly deliver notice
thereof to all Holders. The Company shall cause notice of the execution of such supplemental indenture to be delivered to each Holder, at its address appearing on the Note Register provided for in this Indenture, within 20 days after execution
thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. 
 (c) The
Company shall not become a party to any Merger Event unless its terms are consistent with this Section 17.07. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into cash,
shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, as set forth in Section 17.01 and Section 17.02 prior to the effective time of such Merger Event. 

  
 127 

 (d) The above provisions of this Section shall similarly apply to successive
Merger Events. 
 (e) Notwithstanding the Conversion Rate adjustment provisions described in
Section 17.04(a) through 17.04(e), no adjustment to the Conversion Rate shall be made pursuant to such provisions in the event of any dividend, distribution, share split, share combination or issuance upon a Merger
Event to which the provisions under this Section 17.07 apply. 
 Section 17.08. Certain Covenants.

 (a) The Company covenants that it shall (i) at all times reserve and keep available, free from preemptive rights, out
of its authorized but unissued shares of Common Stock or shares held in treasury, for the purpose of effecting the conversion of Notes, the full number of shares of Common Stock then issuable upon the conversion of all Notes then outstanding (other
than Additional Shares that may be issuable on the conversion of the then outstanding Notes in connection with a Make-Whole Fundamental Change), and (ii) at all times after the Share Increase Approval (as defined in the Note Purchase
Agreement), if obtained, reserve and keep available, free from preemptive rights, out of its authorized but unissued shares of Common Stock or shares held in treasury, for the purpose of effecting the conversion of Notes, the full number of shares
of Common Stock then issuable upon the conversion of all Notes then outstanding (including Additional Shares that may be issuable on the conversion of the then outstanding Notes in connection with a Make-Whole Fundamental Change). 

(b) The Company covenants that all shares of Common Stock issued upon conversion of Notes will be duly authorized, fully paid
and non-assessable by the Company and free from all Taxes, liens and charges with respect to the issue thereof. 

(c) The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder
require registration with or approval of any governmental authority under any federal or state law before such shares of Common Stock may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and
interpretations of the SEC, secure such registration or approval, as the case may be. 
 (d) The Company further covenants
that if at any time the Common Stock shall be listed on any national securities exchange or automated quotation system the Company will 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 Notes. 
 Section 17.09. Responsibility of Trustee. The Trustee
and any 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 

  
 128 

 
supplemental indenture provided to be employed, in making the same. The Trustee and any Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of
any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion 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 Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the
purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 17. 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 17.07 relating either to the kind or amount of shares of stock or securities
or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 17.07 or to any adjustment to be made with respect thereto, may accept (without any
independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in conclusively relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee and the
Conversion Agent (if other than the Trustee) prior to the execution of any such supplemental indenture in addition to any other deliverables required hereunder in connection with the execution of such supplemental indenture) with respect
thereto. 
 Section 17.10. Notice to Holders Prior to Certain Actions. In case of any: 

(a) action by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant to
Section 17.04; 
 (b) Merger Event; or 

(c) voluntary or involuntary dissolution, liquidation or winding-up of the Company or
any of its Subsidiaries; 
 then, in each case (unless notice of such event is otherwise required pursuant to another provision of this Indenture), the
Company shall cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be delivered to each Holder at its address appearing on the Note Register, as promptly as possible but in any event at least 20 days prior
to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which the
holders of Common Stock of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Merger Event, dissolution, liquidation or
winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other
property deliverable upon such Merger Event, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such action by the Company
or one of its Subsidiaries, Merger Event, dissolution, liquidation or winding-up. 

  
 129 

 Section 17.11. Stockholder Rights Plans. If the Company has a stockholder
rights plan in effect upon conversion of the Notes, each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon
such conversion shall bear such legends, if any, in each case as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time. However, if, prior to any conversion of Notes, the rights have separated
from the shares of Common Stock in accordance with the provisions of the applicable stockholder rights plan, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of the
Common Stock Distributed Property, subject to readjustment in the event of the expiration, termination or redemption of such rights, all as provided in the penultimate paragraph of Section 17.04(c). 

Section 17.12. Ownership Limitations. 

(a) Notwithstanding any other provision of this Indenture, except in the context of a Fundamental Change, during any period of
time in which a Person’s Beneficial Ownership of shares of Common Stock is less than 10%, and such Person is not otherwise an Affiliate of the Company, and for so long as the Common Stock is registered under the Exchange Act, such Person shall
not have the right to convert all or any portion of any of its Notes into shares of Common Stock to the extent that, upon and after giving effect to such conversion, such Person (together with such Person’s Affiliates and any other Persons or
entities whose Beneficial Ownership of shares of Common Stock would be aggregated with such Person’s for purposes of Section 13(d) of the Exchange Act (the “Affiliated Parties”) (including shares of Common Stock held by
any “group” of which such Person or any of its Affiliated Parties is a member)) would have Beneficial Ownership of more than 9.99% of the total number of shares of Common Stock then issued and outstanding. The Company shall not adopt any
shareholder rights plan or take any other action that would have the effect of restricting or adversely affecting a Person’s election to change such foregoing percentage limitation. If at any time the Company shall be required under the Note
Purchase Agreement or pursuant to the Indenture to issue shares of Common Stock to the Permitted Holders, but the issuance of such shares of Common Stock would to the knowledge of the Company exceed the ownership limitations set forth in this
Section 17.12(a), in lieu of issuing such number of shares of Common Stock to the Permitted Holders in excess of the ownership limitations set forth in this Section 17.12(a), the Company shall
issue to the Permitted Holders a Warrant to acquire such shares of Common Stock pursuant to the Purchase Agreement. 
 (b)
For purposes of this Section 17.12, “Beneficial Ownership” means the number of shares of Common Stock beneficially owned by a Person and its Affiliated Parties (and any other Persons or entities acting as a
“group” together with a Person or any of such Holder’s Affiliated Parties) and shall include the number of shares of Common Stock issuable upon conversion of the Notes with respect to which such determination is being made, but shall
exclude the number of shares of Common Stock that would be issuable upon (i) conversion of the remaining, unconverted portion of the Notes beneficially owned by such Person or any of its Affiliated Parties (and any other Persons or entities
acting as a “group” together with such Person or any of such Person’s 

  
 130 

 
Affiliated Parties) and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company exercisable for or convertible into Common Stock that
are subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by such Person or any of its Affiliated Parties (and any other Persons or entities acting as a “group” together with such
Person or any of such Person’s Affiliated Parties). Except as set forth in the preceding sentence, for purposes of Section 17.12(a), Beneficial Ownership shall be calculated (and, for such purpose, whether any Person
or entity forms a “group” with any Person or such Person’s Affiliated Parties will be determined) in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder (or, to the extent that,
as a result of a change in law, regulation or interpretation after the date hereof, the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher Beneficial Ownership for any such
party, then such Beneficial Ownership will be calculated in accordance with Section 16 of the Exchange Act and the rules and regulations thereunder), it being acknowledged by each Person that the Company is not representing to any Person that
such calculation is in compliance with Section 13(d) of the Exchange Act and each Person is solely responsible for any schedules required to be filed in accordance therewith. To the extent that an ownership limitation contained in
Section 17.12(a) applies, the determination of whether the Notes owned by a Person are convertible (in relation to other securities owned by such Person together with its Affiliated Parties (and any other Persons or
entities acting as a “group” together with such Person or any of such Person’s Affiliated Parties)) and of which portion of the Notes owned by such Person is convertible shall be in the sole discretion of such Person, and the
submission of a conversion notice to the Conversion Agent (pursuant to Section 17.02) shall be deemed to be such Person’s determination of whether the Notes owned by such Person are convertible (in relation to other
securities owned by such Person together with any of its Affiliated Parties (and any other Persons or entities acting as a “group” together with such Person or any of such Person’s Affiliated Parties)) and of which portion of such
Notes are convertible, in each case subject to the then applicable ownership limitation (as determined in accordance with Section 17.12(a)), and neither the Company nor the Conversion Agent shall have any obligation to
verify or confirm the accuracy of such determination. In addition, a determination as to any “group” status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations
promulgated thereunder. To ensure compliance with this restriction, the Person will be deemed to represent to the Company each time it delivers a conversion notice (pursuant to Section 17.02) that such conversion notice has
not violated the restrictions set forth in Section 17.12(a). 
 (c) For the avoidance of doubt, if
a Person purports to convert any of its Notes into shares of Common Stock hereunder and any delivery otherwise owed to such Person hereunder is not made, in whole or in part, as a result of the then applicable ownership limitation (as determined in
accordance with Section 17.12), then the Person’s rights under the Notes and this Indenture pursuant to which such delivery was not made will not be extinguished and instead such Notes will be deemed to have never been
converted by such Person and will remain outstanding under this Indenture. 

  
 131 

 Section 17.13. No Voting or Dividend Rights. Except as may be
specifically provided for herein, until the conversion record date in respect of the conversion of such Note: 
 (a) no
Holder of such Note shall have or exercise any rights by virtue hereof as a holder of shares of Common Stock, including, without limitation, the right to vote, to receive dividends and other· distributions as a holder of shares of Common
Stock or to receive notice of, or attend, meetings or any other proceedings of the holders of shares of Common Stock; 
 (b)
the consent of any such Holder as a holder of shares of Common Stock shall not be required with respect to any action or proceeding of the Company; 

(c) no such Holder, by reason of the ownership or possession of such Note, shall have any right to receive any cash dividends,
stock dividends, allotments or rights or other distributions paid, allotted or distributed or distributable to the holders of shares of Common Stock prior to, or for which the relevant record date preceded, the conversion record date in respect of
the conversion of such Note; and 
 (d) no such Holder shall have any right not expressly conferred hereunder or by
applicable law with respect to such Note held by such Holder. 
 For purposes of this Section 17.13,
“conversion record date” means, in respect of the conversion of any Note, the date specified in Section 17.02(i) upon which the Person in whose name shares of Common Stock are issuable upon conversion of such Note
shall be treated as the holder of record of such shares of Common Stock upon the conversion of such Note. 
 ARTICLE 18 

Repurchase of Notes at Option of Holders 

Section 18.01. Repurchase at Option of Holders Upon a Fundamental Change. If a Fundamental Change occurs at any
time, each Holder of Notes outstanding on the Fundamental Change Repurchase Date shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion thereof that is equal
to $1,000 or an integral multiple of $1,000, on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than 20 calendar days or more than 35 calendar days following the date of the Fundamental
Change Company Notice at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase
Price”), unless the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of
accrued and unpaid interest to Holders of record as of such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 18. 

(a) Repurchases of Notes under this Section 18.01 shall be made, at the option of the Holder thereof,
upon: 

  
 132 

 (i) delivery to the Trustee by a Holder of a duly completed notice (the
“Fundamental Change Repurchase Notice”) in the form attached to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in compliance with the Depositary’s procedures for surrendering interests
in Global Notes, if the Notes are Global Notes, in each case on or before the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date; and 

(ii) delivery of the Notes, if the Notes are Physical Notes, to the Trustee at any time after delivery of the Fundamental
Change Repurchase Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Trustee, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of the Depositary,
in each case such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor. 
 The
Fundamental Change Repurchase Notice in respect of any Notes to be repurchased shall state: 
 (A) in the case of Physical
Notes, the certificate numbers of the Notes to be delivered for repurchase; 
 (B) in the case of Global Notes, the CUSIP
identifying the Notes to be delivered for repurchase; 
 (C) the portion of the principal amount of Notes to be repurchased,
which must be $1,000 or an integral multiple thereof; and 
 (D) that the Notes are to be repurchased by the Company pursuant
to the applicable provisions of the Notes and this Indenture; 
 provided, however, that if the Notes are Global Notes, the Fundamental Change
Repurchase Notice must comply with appropriate Depositary procedures. 
 Notwithstanding anything herein to the contrary, any Holder
delivering to the Trustee the Fundamental Change Repurchase Notice contemplated by this Section 18.01 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the
close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Trustee in accordance with Section 18.02. 

The Trustee shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal
thereof. 
 (b) On or before the 20th calendar day after the occurrence of the effective date of a Fundamental Change, the
Company shall provide to all Holders of Notes and the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee) a notice (the “Fundamental Change Company Notice”) of the occurrence of the

  
 133 

 
effective date of the Fundamental Change and of the repurchase right at the option of the Holders arising as a result thereof. In the case of Physical Notes, such notice shall be by first class
mail or, in the case of Global Notes, such notice shall be delivered in accordance with the applicable procedures of the Depositary. Simultaneously with providing such notice, the Company shall publish a notice containing the information set forth
in the Fundamental Change Company Notice in a newspaper of general circulation in The City of New York or publish such information on the Company’s website or through such other public medium as the Company may use at that time. Each
Fundamental Change Company Notice shall specify: 
 (i) the events causing the Fundamental Change; 

(ii) the date of the Fundamental Change; 

(iii) the last date on which a Holder may exercise the repurchase right pursuant to this Article 18; 

(iv) the Fundamental Change Repurchase Price; 

(v) the Fundamental Change Repurchase Date; 

(vi) the name and address of the Paying Agent and the Conversion Agent, if applicable; 

(vii) if applicable, the Conversion Rate then in effect; 

(viii) that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder may be
converted only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of this Indenture; and 

(ix) the procedures that Holders must follow to require the Company to repurchase their Notes. 

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the
validity of the proceedings for the repurchase of the Notes pursuant to this Section 18.01. 
 At the
Company’s request, the Trustee shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the
Company and delivered to the Trustee at least three (3) Business Days before such Fundamental Change Company Notice is required to be sent to the Holders pursuant to this Section 18.01 (unless a shorter notice period
is agreed to by the Trustee), together with an Officers’ Certificate requesting that the Trustee give such Fundamental Change Company Notice and the Trustee shall not be obligated to publish any notice in any newspaper or similar media. 

  
 134 

 (c) Notwithstanding the foregoing, no Notes may be repurchased by the
Company on any date at the option of the Holders upon a Fundamental Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration
resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes). The Trustee will promptly return to the respective Holders thereof any Physical Notes held by it during the acceleration
of the Notes (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for book-entry transfer of the Notes in compliance
with the procedures of the Depositary shall be deemed to have been cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 

Section 18.02. Withdrawal of Fundamental Change Repurchase Notice. 

(a) A Fundamental Change Repurchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal
delivered to the Corporate Trust Office of the Trustee in accordance with this Section 18.02 at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date,
specifying: 
 (i) the principal amount of the Notes with respect to which such notice of withdrawal is being submitted, 

(ii) if Physical Notes have been issued, the certificate number of the Note in respect of which such notice of withdrawal is
being submitted, 
 (iii) the CUSIP for Global Notes in respect of which such notice of withdrawal is being submitted, and

 (iv) the principal amount, if any, of such Note that remains subject to the original Fundamental Change Repurchase Notice,
which portion must be in principal amounts of $1,000 or an integral multiple of $1,000; 
 provided, however, that if the Notes are Global
Notes, the notice must comply with appropriate procedures of the Depositary. 
 Section 18.03. Deposit of Fundamental Change
Repurchase Price. 
 (a) The Company will deposit with the Trustee (or other Paying Agent appointed by the Company, or if
the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.03) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date an amount of money
sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes
surrendered for repurchase (and not withdrawn prior to the close of business on the Business Day 

  
 135 

 
immediately preceding the Fundamental Change Repurchase Date) will be made on the later of (i) the Fundamental Change Repurchase Date (provided the Holder has satisfied the conditions
in Section 18.01) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by
Section 18.01 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Note Register; provided, however, that payments to the Depositary shall be made
by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental
Change Repurchase Price. 
 (b) If by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date, the Trustee
(or other Paying Agent appointed by the Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Fundamental Change Repurchase Date, then, with respect to the Notes that have been
properly surrendered for repurchase and have not been validly withdrawn, (i) such Notes will cease to be outstanding, (ii) interest will cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the
Notes have been delivered to the Trustee or Paying Agent) and (iii) all other rights of the Holders of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase Price and, if applicable, accrued and unpaid
interest). 
 (c) Upon surrender of a Note that is to be repurchased in part pursuant to
Section 18.01, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered.

 (d) Covenant to Comply with Applicable Laws Upon Repurchase of Notes. In connection with any repurchase offer, the
Company will, if required: 
 (e) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act; 
 (f) file a Schedule TO or
any other required schedule under the Exchange Act; and 
 (g) otherwise comply with all federal and state securities laws in
connection with any offer by the Company to repurchase the Notes; 
 in each case, so as to permit the rights and obligations under this Article 18
to be exercised in the time and in the manner specified in this Article 18.

 ARTICLE 19 

Repurchase And Redemption 

Section 19.01. Optional Redemption. 

(a) On or after October 1, 2021 Company may redeem (a “Conversion Price Trigger Redemption”) all or any
portion of the Notes, if the Conversion Price Trigger Daily VWAP of the Common Stock has been at least 150% of the Conversion Price then in effect (x) on the Trading Day immediately preceding the date on which the Company provides the
Redemption Notice and (y) for at least 20 Trading Days (whether or not consecutive) during any 30 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date on which the Company provides the
Redemption Notice in accordance with Section 19.02, at a redemption price for each $1,000 principal amount of Notes to be redeemed (the “Conversion Price Trigger Redemption Price”) equal to the sum of (i)
100% of the principal of Notes to be redeemed, payable in cash, plus (ii) accrued and unpaid interest, if any, to, but excluding, the Redemption Date, payable in
cash; provided, however, that if the Redemption Date falls after a Regular Record Date but on or prior to the immediately succeeding Interest Payment Date, the Company shall not pay accrued and unpaid
interest to any Holder surrendering its Notes for such Conversion Price Trigger Redemption, and shall instead pay the full amount of accrued and unpaid interest on such Interest Payment Date to the Holder of record as of the close of business on
such Regular Record Date. 
 (b) Notwithstanding anything to the contrary under this Article 19 or this Indenture,
unless the Company has elected Cash Settlement in respect of all conversions of Notes for which the relevant Conversion Date occurs after the date on which the Company delivers a Redemption Notice in respect of the relevant redemption pursuant to
Section 19.02 and prior to the close of business on the Scheduled Trading Day immediately preceding the related Redemption Date, in no event shall the Company have the right to effect an Optional Redemption of the Notes at
any time at which a shelf registration statement covering resales of the shares of Common Stock, if any, issuable upon conversion of the Notes, of the type provided in the Registration Rights Agreement, is not effective or the use of such shelf
registration statement is then suspended. 
 (c) No sinking fund is provided for the Notes. 

Section 19.02. Notice of Optional Redemption; Selection of Notes. 

(a) In case the Company exercises its Optional Redemption right to redeem all or, as the case may be, any part of the Notes
pursuant to Section 19.01, it shall fix a date for redemption (each, a “Redemption Date”) and the Company or, at its written request received by the Trustee not less than three Scheduled Trading Days prior
to date of the giving of the Redemption Notice (or such shorter period of time as may be acceptable to the Trustee), the Trustee, in the name of and at the expense of the Company, shall deliver or cause to be delivered a notice of such Optional
Redemption (a “Redemption Notice”) not less than 40 nor more than 60 Scheduled Trading Days prior to the Redemption Date to each Holder of Notes so to be redeemed as a whole or in part at its last address as the same appears on the
Note Register and shall give written notice of the Redemption Date to the Paying Agent (if other than the Trustee); provided, however, that, if the Company shall give such notice, it shall also give written notice of the Redemption
Date to the Trustee. The Redemption Date must be a Business Day. 

  
 137 

 (b) The Redemption Notice, if delivered in the manner herein provided, shall
be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such Redemption Notice or any defect in the Redemption Notice to the Holder of any Note designated for redemption as a
whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. 
 (c) Each
Redemption Notice shall specify: 
 (i) the Redemption Date; 

(ii) the Redemption Price; 

(iii) that on the Redemption Date, the Redemption Price will become due and payable upon each Note to be redeemed, and that
interest thereon, if any, shall cease to accrue on and after the Redemption Date; 
 (iv) the place or places where such
Notes are to be surrendered for payment of the Redemption Price; 
 (v) that Holders may surrender their Notes for conversion
at any time prior to the close of business on the Scheduled Trading Day immediately preceding the Redemption Date;

(vii) the Conversion Rate and, if applicable, the number of Additional Shares added to the Conversion Rate in accordance with
Section 19.03; 
 (viii) the CUSIP or other similar numbers, if any, assigned to such Notes; and

 (ix) in case any Note is to be redeemed in part only, the portion of the principal amount thereof to be redeemed and on
and after the Redemption Date, upon surrender of such Note, a new Note in principal amount equal to the unredeemed portion thereof shall be issued. 

A Redemption Notice shall be irrevocable. 

(d) If fewer than all of the outstanding Notes are to be redeemed, the Trustee shall select the Notes or portions thereof of a
Global Note or the Notes in certificated form to be redeemed (in principal amounts of $1,000 or multiples thereof) by lot, on a pro rata basis or by another method the Trustee considers to be fair and appropriate in accordance with
the customary procedures of the Depositary. If any Note selected for partial redemption is submitted for conversion in part after such selection, the portion of the Note submitted for conversion shall be deemed (so far as may be possible) to be
the portion selected for redemption. 

  
 138 

 Section 19.03. Payment of Notes Called for Redemption. 

(a) If any Redemption Notice has been given in respect of the Notes in accordance with Section 19.02,
the Notes shall become due and payable on the Redemption Date at the place or places stated in the Redemption Notice and at the applicable Redemption Price. On presentation and surrender of the Notes at the place or places stated in the
Redemption Notice, the Notes shall be paid and redeemed by the Company at the applicable Redemption Price. 
 (b) Prior to
the open of business on the Redemption Date, the Company shall deposit with the Paying Agent or, if the Company or a Subsidiary of the Company is acting as the Paying Agent, shall segregate and hold in trust as provided in
Section 4.03 an amount of cash (in immediately available funds if deposited on the Redemption Date), sufficient to pay the applicable Redemption Price of, and, if applicable, an amount of cash (in immediately available
funds if deposited on the Redemption Date), with respect to, all of the Notes to be redeemed on such Redemption Date. Subject to receipt of funds and, if applicable, shares of Common Stock by the Paying Agent, payment for the Notes to be redeemed
shall be made promptly after the later of: 
 (i) the Redemption Date for such Notes; and 

(ii) the time of presentation of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder
thereof in the manner required by this Section 19.03. 
 (iii) The Paying Agent shall, promptly
after such payment and upon written demand by the Company, return to the Company any funds in excess of the applicable Redemption Price. 

Section 19.04. Restrictions on Redemption. The Company may not redeem any Notes on any date if the principal amount of
the Notes has been accelerated in accordance with the terms of this Indenture, and such acceleration has not been rescinded, on or prior to the Redemption Date (except in the case of an acceleration resulting from a Default by the Company in the
payment of the Redemption Price with respect to such Notes). 
 Section 19.05. Mandatory Repurchase Offer. 

(a) Alaska Tax Credits; Asset Dispositions; Events of Loss. Subject to the Intercreditor Agreement and this
Section 19.05(a), if a Company Indenture Party or any Subsidiary of a Company Indenture Party (other than any Excluded Subsidiary) shall at any time or from time to time: 

(i) receive any Alaska Tax Credits or any proceeds thereof; 

(ii) make a Disposition; or 

(iii) suffer an Event of Loss; 

  
 139 

 causing a Company Indenture Party to receive Excess Proceeds, and some or all of such Excess Proceeds remain
after mandatory prepayments are offered and paid on account of the ABL Loan Obligations and Term Loan Obligations (in accordance with the ABL Credit Agreement and Term Credit Agreement, respectively), the Company shall, within ten (10) Business
Days following the Term Lenders and the ABL Lenders declining to use some or all of the Excess Proceeds to mandatorily prepay the Term Loan Obligations and the ABL Loan Obligations, offer to apply 100% of such remaining Excess Proceeds to repurchase
the Notes, in accordance with this Section 19.05. Notwithstanding the foregoing, and provided that no Event of Default has occurred and is continuing, such offer to repurchase (and any obligation to repurchase) the Notes
shall not be required to the extent a Company Indenture Party or such Subsidiary reinvests or commits to reinvest such Excess Proceeds of such Disposition or Event of Loss in capital assets then used or usable in the business of the Company or such
Subsidiary or to repair or replace the property subject to such Event of Loss, in each case, within one year after the date of such Disposition or Event of Loss; provided that (i) if any amount is so committed to be reinvested within such one
year, but is not reinvested within the later to occur of (x) six months of the date of such commitment and (y) the end of such one year period, the Company shall offer to apply 100% of such remaining Excess Proceeds to repurchase the Notes
in accordance with this Section 19.05 without giving further effect to such reinvestment right and (ii) if the subject of such Disposition or Event of Loss is Collateral and the Company chooses to reinvest the
applicable Excess Proceeds, then the Company shall use such Excess Proceeds to acquire assets that constitute Collateral. 

(b) [Intentionally Omitted]. 

(c) Mandatory Redemption Notice. The Company shall, within ten (10) Business Days following the Term Lenders and
the ABL Lenders declining to use some or all of the Excess Proceeds (in the case of the receipt of the Alaska Tax Credits (or the proceeds thereof), an Event of Loss or Disposition subject to Section 19.05(a)) to
mandatorily prepay the Term Loan Obligations and the ABL Loan Obligations (and solely to the extent that the Company has decided not to reinvest all of the remaining Excess Proceeds), make a written offer to each Holder (an “Excess Proceeds
Offer”) (with a copy to the Trustee and the Collateral Trustee) to apply an amount equal to 100% of such remaining Excess Proceeds (the “Excess Proceeds Offer Amount”), to repurchase the Notes, if any are then outstanding,
in accordance with Section 19.05(e) below which offer shall state, among other things, (i) the amount of the Excess Proceeds Offer Amount, (ii) that each Holder shall have twenty (20) Business Days from the
date of commencement of such offer or, in the case of an Excess Proceeds Offer delivered to the Holders by the Trustee, twenty-two (22) Business Days from the Company’s written request to the Trustee
to determine whether to accept such offer and that failure to respond within such twenty (20) Business Day period shall be construed as a rejection of such offer by such Holder, (iii) the repurchase date (which shall be no earlier than
twenty-five (25) Business Days after such offer is commenced and no later than forty (40) Business Days after such offer is commenced, pursuant to the procedures required by the Indenture and described in such offer) (the “Excess
Proceeds Payment Date”) and (iv) the procedures determined by the Company, consistent with the Indenture, that a Holder must follow in order to have its Notes repurchased. Failure to respond within such twenty (20) Business Day
(or, if applicable, twenty-two (22) Business Day) period shall be construed as rejection of such repurchase offer by such Holder. At the 

  
 140 

 
Company’s written request received by the Trustee not less than three Scheduled Trading Days prior to date of the giving of the Excess Proceeds Offer (or such shorter period of time as may
be acceptable to the Trustee), the Trustee, in the name of and at the expense of the Company, shall deliver the Excess Proceeds Offer to the Holders within two (2) Business Days. On the Excess Proceeds Payment Date, the Company will, to the
extent lawful: (i) accept for payment all Notes or portions thereof properly tendered pursuant to the Excess Proceeds Offer (subject to proration); and (ii) deposit with the Paying Agent an amount equal to the payment in respect of all
Notes or portions of Notes so accepted for payment; and (iii) deliver to the Trustee an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being repurchased by the Company. 

(d) If any of the Notes subject to the Excess Proceeds Offer is in the form of a Global Note, then the Company shall modify
such notice to the extent necessary to accord with the procedures of the Depositary applicable to purchases. 
 (e) Amounts
to be applied pursuant to this Section 19.05 to the repurchase of the Notes shall be applied to the outstanding Notes, (A) first, towards payment of accrued and unpaid interest, if any, to the date of purchase (subject
to the right of Holders of record on a Record Date to receive interest on the relevant Interest Payment Date), and (B) second, towards payment of principal amount of the applicable Notes then outstanding under this Indenture (held by Holders
electing to receive their ratable portion of the Excess Payment Offer Amount), at a purchase price in cash equal to 100% of the principal amount of such Notes with all such amounts distributed ratably among the parties entitled thereto in accordance
with the amounts of principal then due to such parties and subject to and in accordance with the terms of the Indenture Documents at a purchase price in cash equal to 100% of the principal amount of such Note(s). If the aggregate purchase price of
the Notes tendered in connection with any Excess Proceeds Offer exceeds the Excess Proceeds Offer Amount (less the fees described in clause (A) above), the Notes will be purchased on a pro rata basis except any Notes represented by a Global
Note will be selected for purchase by such method as The Depository Trust Company or its nominee or successor may require or, where such nominee or successor is the Trustee, a method that most nearly approximates pro rata selection unless otherwise
required by law, but in minimum denominations of $1,000 principal amount and integral multiples thereof. If the aggregate purchase price of the Notes tendered in connection with any Excess Proceeds Offer is less than the Excess Proceeds Offer Amount
(less the fees described in clause (A) above), the Company shall be permitted to use the portion of the Excess Proceeds Offer Amount that is not required to be applied to the purchase of Notes in connection with such Excess Proceeds Offer for
any purpose not prohibited hereunder. 
 (f) In connection with any repurchase of the Notes pursuant to this
Section 19.05, the Company shall: (i) comply with the provisions of Rule 13e-4, Rule 14e-1 (or any successor provision) and any other
tender offer rules under the Exchange Act that may then be applicable and (ii) otherwise comply with all federal and state securities laws. To the extent that the provisions of any securities laws or regulations conflict with the provisions of
this Section 19.05, the Company’s compliance with such laws and regulations shall not in and of itself cause a breach of its obligations under this Section 19.05. 

  
 141 

 (g) For the avoidance of doubt, any written offer to repurchase the Notes
delivered to Holders in accordance with this Section 19.05 shall not impair the right of such Holders to convert the Notes pursuant to the terms of this Indenture prior to the repurchase thereof. 

ARTICLE 20 
 Payments of Fees and
Taxes 
 Section 20.01. Withholding. Any and all payments by or on account of any obligation of the Company or any other
Company Indenture Party under this Indenture shall to the extent permitted by applicable Legal Requirements be made free and clear of and without reduction or withholding for any Taxes. If, however, applicable Legal Requirements (as determined in
the good faith discretion of the applicable Company Indenture Party) require any Tax to be withheld or deducted on any payments by or on account of any obligation of the Company and/or the other Company Indenture Parties under this Indenture,
(i) the applicable Company Indenture Party shall withhold or deduct such Tax in accordance with such Legal Requirements and timely pay the full amount withheld or deducted to the relevant Governmental Authority in accordance with such Legal
Requirements, and (ii) to the extent that the withholding or deduction is made on account of Indemnified Taxes or Other Taxes, the sum payable by the applicable Company Indenture Party shall be increased as necessary so that after any required
withholding or the making of all required deductions (including such deductions and withholdings applicable to additional sums payable under this Section 20.01) the Holder receives an amount equal to the sum it would have
received had no such withholding or deduction been made. 
 Section 20.02. Other Taxes. Without limiting or duplicating
the provisions of Section 20.01, the Company Indenture Parties shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with Legal Requirements. 

Section 20.03. Indemnification. The Company Indenture Parties shall indemnify each Holder, within ten (10) days after
written demand therefor delivered to the Trustee, for the full amount of any Indemnified Taxes or Other Taxes paid by such Holder or required to be withheld and deducted from a payment to such Holder, on or with respect to any payment by or on
account of any obligation of the Company Indenture Parties hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Article 20) and any reasonable expenses arising therefrom or
with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Company by
a Holder shall be conclusive absent manifest error. 
 Section 20.04. Evidence of Payment. As soon as practicable after
any payment of Taxes by any Company Indenture Party to a Governmental Authority as provided in this Article 20, such Company Indenture Party shall deliver to the Holders upon request the original or a certified copy of a receipt issued by
such Governmental Authority evidencing such payment, a copy of any return required by Legal Requirements to report such payment or other evidence of such payment reasonably satisfactory to the Holders. 

  
 142 

 Section 20.05. Forms. A Holder shall, as reasonably requested by the
Company, deliver such documentation prescribed by applicable law or reasonably requested by the Company as will enable to the Company to determine whether or not such Holder is subject to withholding, backup withholding and information reporting.
Notwithstanding anything to the contrary in the immediately preceding sentence, the completion, execution, and submission of such documentation (other than such documentation set forth in the last two sentences of this
Section 20.05 (excluding clause (e) of the penultimate sentence of this Section 20.05) and Section 20.07) shall not be required if in the Holder’s reasonable
judgment such completion, execution or submission would subject such Holder to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Holder. Without limiting the generality of the first
sentence of this Section 20.05, a Holder that is a Foreign Holder shall, to the extent legally entitled to do so, at the time it acquires the Notes and thereafter as reasonably requested by the Company or upon the
expiration, invalidity or obsolescence of any previously delivered form, furnish to the Company: (a) in the case of a Foreign Holder claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to
payments of interest under any Indenture Document, executed copies of U.S. Internal Revenue Service Form W-8BEN or Form W-8BEN-E
establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Indenture Document, U.S. Internal
Revenue Service Form W-8BEN or Form W-8BEN-E establishing an exemption from, or reduction of, U.S. federal withholding Tax
pursuant to the “business profits” or “other income” article of such tax treaty; (b) in the case of a Foreign Holder claiming the benefits of the exemption for portfolio interest under Section 881(c)(3)(A) of the IRC
two (2) accurate and complete originals of the applicable U.S. Internal Revenue Service Form W-8BEN or W-8BEN-E and a
certificate (substantially in the form of Exhibit C(1) or Exhibit C(2), as applicable) to the effect that the Holder (or its direct or indirect partners, as applicable) is not a “bank” within the meaning of
Section 881(c)(3)(A) of the IRC, is not a “10-percent shareholder” within the meaning of Section 881(c)(3)(B) of the IRC and is not a controlled foreign corporation described in
Section 881(c)(3)(C) of the IRC; (c) two (2) executed copies of U.S. Internal Revenue Service Form W-8ECI, (d) to the extent a Foreign Holder is not the beneficial owner, executed copies of U.S.
Internal Revenue Service Form W-8IMY, accompanied by U.S. Internal Revenue Service Form W-8ECI, IRS Form W-8BEN or Form W-8BEN-E, a certificate substantially in the form of Exhibit C(1) or Exhibit C(2), U.S. Internal Revenue Service Form
W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Holder is a partnership and one or more direct or indirect partners of such Foreign Holder are
claiming the portfolio interest exemption, such Foreign Holder may provide a certificate substantially in the form of Exhibit C(2) on behalf of each such direct and indirect partner; or (e) any other form prescribed by applicable law as
a basis for claiming exemption from or reduction in U.S. federal withholding Tax together with such supplementary documentation as may be prescribed by applicable law to permit the Company to determine the withholding or deduction to be made. In
addition, each Holder that is a U.S. Person shall, at the time or times prescribed by applicable law or as reasonably requested by the Company or upon the expiration, invalidity or obsolescence of any previously delivered form, furnish to the
Company (a) two (2) complete and accurate originals of IRS Form W-9, or (b) any other form prescribed by applicable law as a basis for claiming exemption from backup withholding. Each Holder agrees
that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Company in writing of its legal inability to do so. 

  
 143 

 Section 20.06. Refunds. If any Holder determines, in its sole discretion
exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Article 20 (including by the payment of additional amounts pursuant to Section 20.01), it shall
pay to the Company an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all
out-of-pocket expenses (including Taxes) of such Holder and without interest (other than any interest paid by the relevant Governmental Authority with respect to such
refund). The Company, upon the request of such Holder, shall repay to such Holder the amount paid over pursuant to this Section 20.06 (plus any penalties, interest or other charges imposed by the relevant Governmental
Authority) in the event that such Holder is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this Section 20.06, in no event will the Holder be required to pay any
amount to the Company pursuant to this Section 20.06 the payment of which would place the Holder in a less favorable net after-Tax position than the Holder would have been in if the
Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This
Section 20.06 shall not be construed to require any Holder to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the Company or any other Person. 

Section 20.07. FATCA. If a payment made to a Holder under any Note would be subject to U.S. federal withholding Tax imposed
by FATCA if such Holder were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the IRC, as applicable), such Holder shall deliver to the Company at the time or
times prescribed by law and at such time or times reasonably requested by the Company such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the IRC) and such additional documentation reasonably
requested by the Company as may be necessary for the Company to comply with their obligations under FATCA and to determine that such Holder has complied with such Holder’s obligations under FATCA or to determine the amount to deduct and
withhold from such payment. Solely for purposes of this Section 20.07, “FATCA” shall include any amendments made to FATCA after the date of this Indenture. 

Section 20.08. Survival. Without prejudice to the survival of any other agreement of the Company hereunder, the agreements and
obligations of the Company contained in this Article 20 shall survive the payment in full of all amounts due hereunder.

of Counsel to Trustee. Upon any application or demand by the Company to the Trustee or the Collateral Trustee to take any action under any of the provisions of any Indenture Document or the Intercreditor Agreement, the Company shall, if
requested by the Trustee or the Collateral Trustee, furnish to the Trustee or the Collateral Trustee, as the case may be, an Officers’ Certificate and an Opinion of Counsel stating that such action is permitted by the terms of this Indenture
and the Intercreditor Agreement. 
 Each Officers’ Certificate and Opinion of Counsel provided for, by or on behalf of the Company in
this Indenture and delivered to the Trustee and the Collateral Trustee with respect to compliance with this Indenture shall include (i) a statement that the person making such certificate or opinion has read such condition or covenant;
(ii) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based; (iii) a statement that, in the opinion of such person, he or
she has made such examination or investigation as is necessary to enable him or her to express an informed opinion as to whether or not such condition or covenant has been satisfied; and (iv) a statement as to whether or not, in the opinion of
such person, such condition or covenant has been satisfied. 
 In any case where several matters are required to be certified by, or covered
by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or
give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents. 

  
 146 

 Any certificate or opinion of an officer of the Company may be based, insofar as it relates
to legal matters; upon a certificate or opinion of, or representations by, counsel, unless such officer knows that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or opinion of, or representation by, counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the Company unless such counsel knows that the certificate or opinion or representations with respect to such matters are erroneous. 

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or
other instruments under this Indenture, they may, but need not, be consolidated and form one instrument. 
 Section 21.07. Legal
Holidays. In any case where any Interest Payment Date, any Fundamental Change Repurchase Date, any Redemption Date or the Maturity Date is not a Business Day, then any action to be taken on such date need not be taken on such date, but
may be taken on the next succeeding Business Day with the same force and effect as if taken on such date, and no interest shall accrue in respect of the delay. 

Section 21.08. Benefits of Indenture. Nothing in this Indenture or in the Notes, expressed or implied, shall give to any
Person, other than the parties hereto, any Paying Agent, any Conversion Agent, any authenticating agent, any Note Registrar and their respective successors hereunder and the Holders, any benefit or any legal or equitable right, remedy or claim under
this Indenture. 
 Section 21.09. Table of Contents, Headings, Etc. The table of contents and the titles 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 hereof, and shall in no way modify or restrict any of the terms or provisions hereof. 

Section 21.10. Authenticating Agent. The Trustee may appoint an authenticating agent that shall be authorized to act on its
behalf and subject to its direction in the authentication and delivery of Notes in connection with the original issuance thereof and transfers and exchanges of Notes hereunder as fully to all intents and purposes as though the authenticating agent
had been expressly authorized by this Indenture and those Sections to authenticate and deliver Notes. For all purposes of this Indenture, the authentication and delivery of Notes by the authenticating agent shall be deemed to be authentication and
delivery of such Notes “by the Trustee” and a certificate of authentication executed on behalf of the Trustee by an authenticating agent shall be deemed to satisfy any requirement hereunder or in the Notes for the Trustee’s
certificate of authentication. Such authenticating agent shall at all times be a Person eligible to serve as trustee hereunder pursuant to Section 10.08. 

  
 147 

 Any corporation or other entity into which any authenticating agent may be merged or
converted or with which it may be consolidated, or any corporation or other entity resulting from any merger, consolidation or conversion to which any authenticating agent shall be a party, or any corporation or other entity succeeding to the
corporate trust business of any authenticating agent, shall be the successor of the authenticating agent hereunder, if such successor corporation or other entity is otherwise eligible under this Section 21.09, without the
execution or filing of any paper or any further act on the part of the parties hereto or the authenticating agent or such successor corporation or other entity. 

Any authenticating agent may at any time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at
any time terminate the agency of any authenticating agent by giving written notice of termination to such authenticating agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time any
authenticating agent shall cease to be eligible under this Section, the Trustee may appoint a successor authenticating agent (which may be the Trustee), shall give written notice of such appointment to the Company and shall deliver notice of such
appointment to all Holders as the names and addresses of such Holders appear on the Note Register. 
 The Company agrees to pay to the
authenticating agent from time to time reasonable compensation for its services although the Company may terminate the authenticating agent, if it determines such agent’s fees to be unreasonable. 

The provisions of Section 10.02, Section 10.03, Section 10.04,
Section 10.05 and this Section 21.10 shall be applicable to any authenticating agent. 

If an authenticating agent is appointed pursuant to this Section 21.10, the Notes may have endorsed thereon, in
addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form: 
  

	
	                                      
              , as Authenticating Agent, certifies that this is one of the Notes described in the within-named Indenture.
	
	By:                                     
                            
	Authorized Officer

 Section 21.11. Execution in Counterparts. This Indenture may be executed in any number of
counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument. The exchange of copies of this Indenture and of signature pages by facsimile or PDF
transmission shall constitute effective execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be
deemed to be their original signatures for all purposes. 
 Section 21.12. Severability. In the event any
provision of this Indenture or in the Notes shall be invalid, illegal or unenforceable, then (to the extent permitted by law) the validity, legality or enforceability of the remaining provisions shall not in any way be affected or impaired and such
provision shall be ineffective only to the extent of such invalidity, illegality or unenforceability. 

  
 148 

 Section 21.13. Waiver of Jury Trial. EACH OF THE COMPANY, EACH GUARANTOR
AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED
HEREBY. 
 Section 21.14. Force Majeure. In no event shall the Trustee 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, strikes, work stoppages, 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 that
are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances. 

Section 21.15. Calculations. Except as otherwise provided herein, the Company shall be responsible for making all
calculations called for under the Notes. These calculations include, but are not limited to, determinations of the Stock Price, the Last Reported Sale Prices of the Common Stock, the Daily VWAPs, the Daily Conversion Values, the Daily Settlement
Amounts, the Conversion Price Trigger Daily VWAPs, accrued interest payable on the Notes, and the Conversion Rate of the Notes. The Company shall make all these calculations in good faith and, absent manifest error, the Company’s calculations
shall be final and binding on Holders of Notes. The Company shall provide a schedule of its calculations, and any other relevant information, 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 Company’s calculations without independent verification. The Trustee and the Conversion Agent shall not have any liability or responsibility in connection with any calculation or
information relating to any calculation. 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. The Trustee will forward the Company’s
calculations to any Holder of Notes upon the written request of that Holder at the sole cost and expense of the Company. 

Section 21.16. USA PATRIOT Act. The parties hereto acknowledge that in accordance with Section 326 of the USA PATRIOT
Act, the Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies each person or legal entity that establishes a
relationship or opens an account with the Trustee. The parties to this Indenture agree that they will provide the Trustee with such information as it may request in order for the Trustee to satisfy the requirements of the USA PATRIOT Act. 

Section 21.17. Intercreditor Agreement. Each Holder of a Note, by accepting such Note, agrees that, for purposes of the
Intercreditor Agreement, (i) the Collateral Trustee shall be the “Convertible Noteholder Trustee” thereunder, (ii) this Indenture shall constitute the “Convertible Note Indenture” thereunder and all
references to the “Convertible Note Indenture” contained therein shall be deemed to refer to this Indenture, and (iii) all of the Obligations shall constitute “Convertible Note Indenture Obligations”
thereunder. The Trustee and the Collateral Trustee shall be bound by the terms of the Intercreditor Agreement and each 

  
 149 

 
Holder of a Note, by accepting such Note or beneficial interest therein, agrees to all the terms and provisions of the Intercreditor Agreement and the other Security Documents. Notwithstanding
anything to the contrary herein or in the other Indenture Documents, (i) this Indenture, the Liens and security interests granted to the Collateral Trustee pursuant to the Security Documents and all rights and obligations of the Trustee and
Collateral Trustee under the Indenture Documents are expressly subject to the Intercreditor Agreement and (ii) the exercise of any right or remedy by the Trustee or the Collateral Trustee under the Indenture Documents is subject to the
limitations and provisions of the Intercreditor Agreement. The Holders authorize the Collateral Trustee to communicate with the Term Agent and Term Lenders under the Term Credit Agreement, the ABL Loan Agent and ABL Lenders under the ABL
Credit Agreement, and any other Person who is, or becomes a party to the Intercreditor Agreement, with respect to any matter, including, without limitation, the Obligations, the Term Loan Obligations, the ABL Loan Obligations, the Intercreditor
Agreement, the Term Documents and ABL Documents, the Indenture Documents, and any other matter relating to, or arising out of such matters. Each Holder of a Note, by accepting such Note, agrees and hereby authorizes and directs the Collateral
Trustee and Trustee to execute the Intercreditor Agreement. Each Holder, by accepting a Note, hereby agrees that such Holder shall comply with the provisions of the Intercreditor Agreement applicable to it in its capacities as such to the same
extent as if such Holder were party thereto. Without limiting any of the rights and protections (including indemnities) of the Trustee or Collateral Trustee hereunder and notwithstanding any provisions in this Indenture or the other Indenture
Documents to the contrary, in the event of any conflict or inconsistency between the terms of the Intercreditor Agreement and the terms of this Indenture or the other Indenture Documents, the terms of the Intercreditor Agreement shall govern.

indenture, loan or other agreement of the Company or its Subsidiaries or of any other Person, in each case, which does not constitute an Indenture Document. Any such indenture, loan or other agreement may not be used to interpret this Indenture.

 Appendix A 

Provisions Relating to the Notes 
 1.1
Capitalized Terms. Capitalized terms used but not defined in Appendix A shall have the meanings given to them in the Indenture. 
 1.2 Global
Notes. 
 (a) If Notes are eligible for book-entry settlement with the Depositary, such Notes may be represented by one or more Notes in
global form (each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note
shall be effected through the Depositary in accordance with this Indenture (including the restrictions on transfer set forth herein) and the procedures of the Depositary therefor. 

(b) A Global Note may not be transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee
of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary and (ii) for exchange of a Global Note or a portion thereof
for one or more Physical Notes in accordance with this Appendix A. 
 (c) The Depositary shall be a clearing agency registered under the
Exchange Act. The Company initially appoints The Depository Trust Company to act as Depositary with respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede & Co.,
as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co. 
 (d) If (i) the Depositary
notifies the Company at any time that the Depositary is unwilling or unable to continue as depositary for the Global Notes and a successor depositary is not appointed within 90 days, (ii) the Depositary ceases to be registered as a clearing
agency under the Exchange Act and a successor depositary is not appointed within 90 days or (iii) an Event of Default with respect to the Notes has occurred and is continuing and a beneficial owner of any Note requests that its beneficial
interest therein be issued as a Physical Note, the Company shall execute, and the Trustee, upon receipt of an Officers’ Certificate, an Opinion of Counsel, and a Company Order for the authentication and delivery of Notes, shall authenticate and
deliver (x) in the case of clause (iii), a Physical Note to such beneficial owner in a principal amount equal to the principal amount of such Note corresponding to such beneficial owner’s beneficial interest and (y) in the case of
clause (i) or (ii), Physical Notes to each beneficial owner of the related Global Notes (or a portion thereof) in an aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such Global Notes, and
upon delivery of the Global Notes to the Trustee such Global Notes shall be canceled. 
 (e) Physical Notes issued in exchange for all or a
part of the Global Note pursuant to this Section 1.2 of Appendix A shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants
or otherwise, or, in the case of clause (iii) of the immediately preceding paragraph, the relevant beneficial owner, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical Notes to the
Persons in whose names such Physical Notes are so registered. 

  
 154 

 (f) At such time as all interests in a Global Note have been converted, canceled,
repurchased, redeemed or transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with standing procedures and existing instructions between the Depositary and the Custodian. At any time prior to such
cancellation, if any interest in a Global Note is exchanged for Physical Notes, converted, canceled, repurchased, redeemed or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part
of such Global Note, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an
endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase. 

(g) None of the Company, the Trustee (acting in any capacity) or any agent of the Company or the Trustee shall have any responsibility or
liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership interests, or for any
action or inaction of the Depositary. 
 Each Note that is a Global Note shall be subject to the restrictions on transfer set forth in this
Section 1.2 of Appendix A (including the legend set forth below): 
 THIS NOTE IS A GLOBAL NOTE WITHIN THE MEANING
OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITORY OR A NOMINEE THEREOF. THIS NOTE MAY NOT BE EXCHANGED IN WHOLE OR IN PART FOR A NOTE REGISTERED, AND NO TRANSFER OF THIS NOTE IN WHOLE OR IN PART MAY BE
REGISTERED, IN THE NAME OF ANY PERSON OTHER THAN SUCH DEPOSITORY OR A NOMINEE THEREOF, EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE. 

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (“DTC”), A NEW YORK
CORPORATION, TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND
ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL IN AS MUCH AS THE REGISTERED
OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

shall be subject to the restrictions on transfer set forth in this Section 1.2(h) of Appendix A (including the legend set forth below):

 [FORM OF REVERSE OF NOTE] 

SAExploration Holdings, Inc. 

6.00% Senior Secured Convertible Note due 2023 

This Note is one of a duly authorized issue of Notes of the Company, designated as its 6.00% Senior Secured Convertible Notes due 2023 (the
“Notes”), limited to the aggregate principal amount of $60,000,000, all issued or to be issued under and pursuant to a Senior Secured Convertible Notes Indenture dated as of September 26, 2018 (the
“Indenture”), among the Company, the Guarantors named therein and Wilmington Savings Fund Society, FSB (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a
description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Capitalized terms used in this Note and not defined in this Note shall have the respective
meanings set forth in the Indenture. 
 In case certain Events of Default shall have occurred and be continuing, the principal of, and
interest on, all Notes may be declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to
the conditions and certain exceptions set forth in the Indenture. 
 The Notes are secured, equally and ratably, by a senior security in the
Collateral pursuant to the Security Agreement and the Security Documents referred to in the Indenture. The Notes are secured by a pledge of Collateral pursuant to the Security Documents. The Notes are subject to the terms of the Intercreditor
Agreement. 
 The payment by the Company of the principal of, interest and Additional Interest, if any, on the Notes is fully and
unconditionally guaranteed on a joint and several senior secured basis by each of the Guarantors to the extent set forth in the Indenture. 

Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change
Repurchase Price on the Fundamental Change Repurchase Date and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent to collect such payments in respect of the Note. The Company
will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the
Notes, and in certain other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures
modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time outstanding may
on behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences. 

  
 164 

 No reference herein to the Indenture and no provision of this Note or of the Indenture shall
alter or impair the obligation of the Company, which is absolute and unconditional, to pay or deliver, as the case may be, the principal (including the Fundamental Change Repurchase Price, if applicable) of, the Redemption Price of (if applicable),
accrued and unpaid interest on, and the consideration due upon conversion of, this Note at the place, at the respective times, at the rate and in the lawful money and/or shares of Common Stock, as the case may be, herein prescribed. 

The Notes are issuable in registered form without coupons in minimum denominations of $1,000 principal amount and integral multiples
thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of other
authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith as a result of the name of
the Holder of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange. 

Subject to certain limitations, the Notes shall be redeemable at the Company’s option in accordance with the terms and conditions
specified in the Indenture. 
 Upon the occurrence of a Fundamental Change, the Holder has the right, at such Holder’s option, to
require the Company to repurchase for cash all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change
Repurchase Price. 
 Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, at any time prior to the
close of business on the Business Day immediately preceding the Maturity Date, to convert any Notes or any portion thereof that is $1,000 or an integral multiple thereof, into cash, shares of Common Stock or a combination of cash and shares of
Common Stock, as applicable, at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture. 

In addition to the rights provided to Holders of Notes under the Indenture, Holders shall have all the rights set forth in the Registration
Rights Agreement dated as of September 26, 2018, among the Company and the Holders.
