At the option of the Holder and subject to the other provisions of Section 3.07 and to Section 3.11, Notes may be exchanged for
other Notes of any authorized denominations and of a like aggregate Principal Amount and tenor, upon surrender of the Notes to be exchanged at such office or agency. Whenever any Notes are so surrendered for exchange, the Company shall execute, and

exchange of Notes, other than exchanges pursuant to Section 3.05 not involving any transfer. 
 (b) Neither the Company nor the
Registrar shall be required to exchange or register a transfer of any Note in the circumstances set forth in Section 3.11(a)(iv). Neither any members of, or participants in, the Depository (collectively, the “Agent Members”)
nor any other Persons on whose behalf any Agent Member may act shall have any rights under this Indenture with respect to any Global Note registered in the name of the Depository or any nominee thereof, or under any such Global Note, and the
Depository or such nominee, as the case may be, may be treated by the Company, the Guarantors, the Trustee and any agent of the Company, the Guarantors or the Trustee as the absolute owner and Holder of such Global Note for all purposes whatsoever.
The Trustee shall have no responsibility or obligation to any Agent Members or any other Person on whose behalf Agent Members may act with respect to (i) any ownership interests in the Global Note, (ii) the accuracy of the records of the
Depository or its nominee, (iii) any notice required hereunder or (iv) any payments under or with respect to the Global Note. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Guarantors, the Trustee or any agent
of the Company, the Guarantors or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or such nominee, as the case may be, or impair, as between the Depository, its Agent Members and
any other Person on whose behalf an Agent Member may act, the operation of customary practices of such  

  
 39 








 
Persons governing the exercise of the rights of a Holder of any Note. The registered Holder of a Global Note may grant proxies and otherwise authorize any Person, including Agent Members and

Note must surrender such Note in accordance with the provisions of Section 3.11 and deliver any additional documentation reasonably required by the Company, the Trustee or the Registrar in connection with such exchange. 

(b) Significant Event of Default. Upon the occurrence and during the continuation of any Significant Event of Default or the
acceleration of the Obligations after the occurrence of any Event of Default (which acceleration has not been rescinded), such restrictions regarding the transfer of the Notes set forth in the Purchase Agreement shall not apply to restrict the

 Section 3.09 Mutilated, Destroyed, Lost and Stolen Notes 

(a) If any mutilated Note is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Note of like tenor and Principal Amount and bearing a number not contemporaneously outstanding.

delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Note and (ii) such security or indemnity as may be required by them sufficient in the judgment of the Trustee and the
Company to protect the Company, the Trustee or any agent from any loss which any of them may suffer if a Note is replaced, then, in the absence of notice to the Company or the Trustee that such Note has been acquired by a protected purchaser, the
Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and Principal Amount and bearing a number not contemporaneously outstanding. 

In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Note, pay such Note.

by the Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 

Every new Note issued pursuant to this Section 3.09 in lieu of any destroyed, lost or stolen Note shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Notes
duly issued hereunder. 
 The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and
remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes. 
 (b) Notes outstanding at any time are
all Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section as not outstanding. A Note does not cease to be outstanding because the Company, or an Affiliate of
the Company, holds the Note. 
 If a Note is replaced pursuant to clause (a) of this Section 3.09, it ceases to be outstanding
unless the Trustee and the Company receive proof satisfactory to them that the replaced security is held by a protected purchaser.

Make-Whole Payment) on all the outstanding Notes (or portions thereof) to be redeemed or maturing, as the case may be, and the Paying Agent is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture,
then on and after that date the Principal Amount of such Notes (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

operate as a redemption or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation. The Notes so acquired, while held by or on behalf of the Company or any of its
Subsidiaries, shall not entitle the Holder thereof to convert the Notes. The Company may not issue new Notes to replace Notes it has paid in full or delivered to the Trustee for cancellation.

Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action; provided, however, that if such deposit is made on the due date, such deposit shall be
received by the Paying Agent by 11:00 a.m. New York City time, on such date.

by the Trustee upon the trusts herein contained and upon such payment by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability with respect to such sums.

 (b) The Credit Parties shall use commercially reasonable efforts to arrange for all of such
insurance (and the corresponding insurance certificates) to provide that no cancellation, material reduction in amount or material change in coverage thereof shall be effective until at least thirty (30) days after receipt by the Collateral
Trustee of written notice thereof (except with respect to cancellation as a result of a payment default, such cancellation shall not be effective until at least ten (10) days after receipt by the Collateral Trustee of written notice thereof)
and if an endorsement providing such notice is commercially impracticable by any Credit Party’s carrier (or such carrier(s) otherwise refuse to deliver such notice), such Credit Party will use its commercially reasonable efforts to provide
thirty (30) days or ten (10) days, as applicable, notice to the Collateral Trustee prior to the cancellation, material reduction in amount or material change in coverage. All such insurance (and the corresponding insurance certificates)
shall (i) name the Collateral Trustee as mortgagee (in the case of property insurance) or additional insured on behalf of the Secured Parties (in the case of liability insurance) or loss payee (in the case of property insurance), as applicable
and (ii) be reasonably satisfactory in all other respects to the Requisite Holders (it being agreed that the amount, adequacy and scope of the policies of insurance of the Credit Parties in effect as of the Term Loan Closing Date are acceptable
to the Requisite Holders as of the Closing Date). 
 (c) If such Credit Party fails to obtain any insurance as required by this Section, the
Collateral Trustee may obtain such insurance, acting at the direction of the Requisite Holders, at such Credit Party’s expense. By purchasing such insurance, neither the Collateral Trustee nor the Requisite Holders shall be deemed to have
waived any Default or Event of Default arising from the Credit Party’s failure to maintain such insurance or pay any premiums therefor. 

(d) With respect to Property subject to a Mortgage, each Credit Party shall obtain flood insurance in such total amount as the Requisite
Holders or the Collateral Trustee (at the direction of the Requisite Holders) may from time to time reasonably require, if at any time the area in which any improvements located on any Property subject to a Mortgage is designated a “flood

1973, as amended from time to time. 
 (e) Promptly following the reasonable request of the Requisite Holders or the Collateral Trustee
acting at the direction of the Requisite Holders, each Credit Party shall deliver to the Collateral Trustee and the Holders a report of a reputable insurance broker with respect to such Credit Party’s insurance and such supplemental reports
with respect thereto as the Requisite Holders or the Collateral Trustee acting at the direction of the Requisite Holders, may from time to time reasonably request. 

(f) No Credit Party shall knowingly take any action that is reasonably likely to be the basis for termination, revocation or denial of
any insurance coverage required to be maintained under any Mortgage of any Credit Party or that could be the basis for a defense to any claim under any Insurance Policy maintained in respect of the Property subject to a Mortgage, and each Credit
Party shall otherwise comply in all material respects with all Insurance Requirements in respect of the premises; provided, however, that the foregoing to the contrary notwithstanding, such Credit Party may, at its own expense and so long as
it provides prompt written notice  

  
 59 








 
thereof to the Collateral Trustee, (i) contest the applicability or enforceability of any such Insurance Requirements by appropriate legal proceedings, the prosecution of which does not
constitute a basis for cancellation or revocation of any insurance coverage required under this Section 4.05 or (ii) cause the Insurance Policy or any other insurance policy containing any such Insurance Requirement to be replaced by a new
policy complying with the provisions of this Section 4.05 (and terminate the policy that is so replaced).

zoning, building, Environmental Law, ordinance, code or approval or any building permits or any restrictions of record or agreements affecting the Real Property) and decrees and orders of any Governmental Authority, whether now in effect or
hereafter enacted, except in each cases where the failure to comply, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Change; provided that nothing in this Section 4.06(b) shall prevent
(A) Dispositions of Property in accordance with Section 4.32; or (B) the withdrawal by any Credit Party of its qualification as a foreign corporation in any jurisdiction where such withdrawal, individually or in the aggregate, could
not reasonably be expected to result in a Material Adverse Change. 
 (c) Except as expressly permitted herein or in any other Equity
Document or Indenture Document, each Credit Party shall (a) perform and observe all material terms and provisions of each contract, instrument, agreement or other document (after giving effect to all cure periods set forth therein), in each

contract, instrument, agreement or other document in full force and effect, and (c) enforce each such contract, instrument, agreement or other document in accordance with its terms provided, however, without limiting the other provisions set

faith, with respect to which reserves in conformity with GAAP have been provided and (y)

result in a Material Adverse Change.

(a) Each Credit Party shall pay and discharge before the same shall become delinquent, (i) all taxes, assessments, and governmental
charges or levies imposed upon it or upon its income or profits or Property that are material in amount, prior to the date on which penalties attach thereto and (ii) all lawful claims that are material in amount which, if unpaid, might by law
become a Lien (other than Permitted Liens) upon its Property; provided, however, that no Credit Party shall be required to pay or discharge any such tax, assessment, charge, levy, or claim which is being contested in good faith and by appropriate
proceedings, and with respect to which reserves in conformity with GAAP have been provided. 
 (b) Each Credit Party shall timely and
correctly file all Tax returns required to be filed by it, except where the failure to do so would not reasonably be expected to result in a Material Adverse Change.

perform their Obligations.

details are given, if applicable, and (ii) based on relevant laws as in effect on the date of such Opinion of Counsel, all financing statements, financing statement amendments and continuation statements have been executed and filed that are
necessary as of such date and during the succeeding 12 months fully to preserve and perfect the Liens securing the Obligations, to the extent the Liens securing the Obligations can be perfected by the filing of a financing statement, 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 12 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 and in that case the Credit Parties shall cause a continuation statement
or amendment to be timely filed so as to maintain such Liens and security interests securing the Obligations; or (2) stating that, in the opinion of such counsel, no such action is necessary to maintain such Liens securing the Obligations as

in cases where Trust Indenture Act § 314(d) requires that such certificate or opinion be made by an independent Person, which Person will be an independent engineer, appraiser or other expert reasonably satisfactory to the Trustee. The
determination as to whether an independent Person needs to sign such certificate or opinion shall be made by the Company and neither the Trustee nor the Collateral Trustee shall have any responsibility related thereto. Notwithstanding anything to
the contrary in this Article 5, the Company shall not be required to comply with all or any portion of Trust Indenture Act § 314(d) if it determines, in good faith based on advice of counsel, that under the terms of Trust Indenture Act §
314(d) and/or any interpretation or guidance as to the meaning thereof of the Commission or its staff, including “no action” letters or exemptive orders, all or any portion of Trust Indenture Act § 314(d) is inapplicable to one or a
series of released Collateral. 
 Section 5.06 Further Assurances. 

(a) Reserved. 
 (b) Subject to
the applicable limitations set forth in the Security Documents and this Indenture (including with respect to Excluded Property), to the extent that any Liens securing the Obligations are not perfected as of the First Issue Date (other than as
permitted in this Indenture, the Intercreditor Agreement, the Subordination Agreement or any Security Document) the Company will take such action as to have such Liens perfected prior to the date that is forty-five (45) days from the First
Issue Date unless otherwise set forth in Schedule 4.28. 

  
 98 








 (c) Notwithstanding anything to the contrary in this Indenture, the Notes, the Intercreditor
Agreement, the Subordination Agreement or in any Security Document (without limiting the provisions of the sentence immediately following this sentence), in no event shall the Collateral Trustee or the Trustee make any representation as to or be
responsible for, or have any duty or obligation with respect to, the recording, filing, registering, perfection, protection or maintenance of the security interests or Liens intended to be created by this Indenture or the Security Documents
(including without limitation the filing or continuation of any UCC financing statements, mortgages, security agreements or similar documents or instruments in any U.S. or foreign jurisdiction), nor shall the Collateral Trustee or the Trustee be
responsible for, and neither the Collateral Trustee nor the Trustee makes any representation regarding, the validity, effectiveness or priority of any of the Security Documents or the security interests or Liens intended to be created thereby. If,
at the direction of the Requisite 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 Requisite 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). Neither the Trustee nor the Collateral Trustee shall have any duty to ascertain or inquire as to the performance or observance of any of the terms of this Indenture or
any Security Document by the Company or any Credit Party or any other Person that is a party thereto or bound thereby. 
 Section 5.07
Release of Collateral. 
 (a) The Liens securing the Obligations on the Collateral shall be automatically terminated and released
without further action by any party (other than satisfaction of any requirements in the Security Documents, the Subordination Agreement and the Intercreditor Agreement, 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; (ii) upon payment in full of principal, interest and all other Obligations of the Company under the Notes issued under this Indenture;
(iii) at the direction of the Requisite Holders or as otherwise may be required by the Security Documents; 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 Credit Party
may request and instruct the Collateral Trustee to, on behalf of each Holder of Notes, (i) execute and deliver to any Credit 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 Credit Party, as the case may be; and Collateral Agent shall promptly take such
actions provided that any such release complies with the terms of this Indenture, the Intercreditor Agreement, the Subordination Agreement and the Security Documents and is accompanied by an Officers’ Certificate and Opinion of Counsel. 

  
 99 








 (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, the Intercreditor Agreement, the Subordination Agreement 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, the Subordination 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.

payable under this Article 6) 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 Government 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 6.04 Evidence of Payment 

Upon request by the Holders after any payment of Taxes by the Company to a Governmental Authority as provided in this Article 6, the Company
shall deliver to the Holders the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of any return required by Applicable Laws to report such payment or other evidence of such payment
reasonably satisfactory to the Holders. 
 Section 6.05 Forms 

A Holder shall, at the time or times prescribed by Applicable Law or as reasonably requested by the Company, deliver such other 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. Without limiting the generality of the
foregoing, a Holder that is not a “United States person” within the meaning of Section 7701(a)(30) of the Code (a “Non-U.S. Holder”) shall, 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) two (2) accurate and complete originals of the applicable U.S. Internal Revenue Service Form W-8 and a certificate
(substantially in the form of Exhibit D(1) or Exhibit D(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 Code, is not a “10-percent shareholder” within the meaning of Section 881(c)(3)(B) of the Code and is not a controlled foreign corporation described in Section 881(c)(3)(C) of the Code, or (b) 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 “United States person” within the meaning of Section 7701(a)(30) of the Code 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. 
 Section 6.06 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 Article 6 (including by the payment of additional amounts pursuant to Section 6.01), 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 6.06 (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 6.06, in no event will the Holder be 

  
 101 








 
required to pay any amount to the Company pursuant to this Section 6.06 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 6.06
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 6.07 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 Code, 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 Code) 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. 

Section 6.08 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 6 shall survive the payment in full of all amounts due hereunder. 
 ARTICLE 7 

CONVERSION 

Section 7.01 Right to Convert 

(a) Subject to and upon compliance with the provisions of this Indenture (and in the case of a Permitted Holder, subject to such further
restrictions, to the extent applicable, set forth in the Purchase Agreement regarding the Permitted Holders’ obligation to maintain an aggregate minimum percentage ownership of the aggregate Principal Amount outstanding under the Notes
provided that upon the occurrence and during the continuation of any Significant Event of Default or the acceleration of the Obligations after the occurrence of any Event of Default (which acceleration has not been rescinded), such
restrictions regarding the Permitted Holders’ obligation to maintain an aggregate minimum percentage ownership of the aggregate Principal Amount outstanding under the Notes set forth in the Purchase Agreement shall not apply to restrict the
Permitted Holders in any manner), each Holder shall have the right, at such Holder’s option, at any time commencing on June 15, 2014 until the Close of Business on the Business Day immediately preceding the Maturity Date, to convert the
Principal Amount of any such Notes, or any portion of such Principal Amount, into shares of Common Stock. 

  
 102 








 (b) Notwithstanding the foregoing, if a Holder has already delivered a Fundamental Change
Purchase Notice with respect to a Note under Section 8.01, such Holder may convert such Note only if such Holder first withdraws the related Fundamental Change Purchase Notice pursuant to Section 8.03. If a Holder has surrendered such
Holder’s Note for required purchase in connection with a Fundamental Change, such Holder’s right to withdraw the related Fundamental Change Purchase Note and convert each Note that is subject thereto will terminate at the Close of Business
on (i) the Business Day immediately preceding the relevant Fundamental Change Purchase Date or (ii) in the case of a Default by the Company in the payment of the Fundamental Change Purchase Price with respect to such Note, the Business Day
immediately preceding the day on which such Default is no longer continuing. 
 (c) Provisions of this Indenture that apply to conversion of
all of a Note also apply to conversion of a portion of a Note. 
 (d) A Holder of Notes is not entitled to any rights of a holder of shares
of Common Stock until such Holder has converted its Notes, and only to extent such Notes are deemed to have been converted into shares of Common Stock pursuant to this Article 7. 

(e) Notwithstanding any other provision of this Indenture to the contrary, (i) prior to obtaining Stockholder Approval with respect to
the 19.99% Proposal (A) no Holder shall be entitled to receive, and the Company shall not be obligated to pay (whether in cash or in shares of Common Stock), the Voluntary Conversion Make-Whole Payment in connection with a voluntary conversion
by a Holder of all or any portion of the Principal Amount of any Notes into shares of Common Stock pursuant to this Section 7.01 and (B) the Company shall not be permitted to exercise its conversion option with respect to all or any
portion of the Principal Amount of any Notes into shares of Common Stock pursuant to Section 7.07; and (ii) no Holder may voluntarily convert, and the Company may not require a Holder to convert pursuant to Section 7.07, any portion
of the Principal Amount of any Notes into shares of Common Stock, to the extent that (A) such conversion is limited pursuant to the provisions of Section 7.09(a), or (B) upon and after giving effect to such conversion (including the
issuance of any shares of Common Stock in satisfaction of any Make-Whole Payment, as applicable), such Holder (together with such Holder’s Affiliates and any other persons or entities whose Beneficial Ownership (as defined below) of Common
Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act (the “Affiliated Parties”) (including shares held by any “group” of which the Holder or any of its Affiliated Parties
is a member)), would have Beneficial Ownership of more than the applicable ownership limitation under Section 7.01(f) below. 
 (f)
Notwithstanding the provisions of Section 7.01(e) above, during any period of time in which a Holder’s Beneficial Ownership of Common Stock is less than 5%, a Holder shall not have the right to convert all or any portion of the Principal
Amount of any Notes into shares of Common Stock to the extent that upon and after giving effect to such conversion (and issuance of any shares of Common Stock in satisfaction of any Make-Whole Payment, as the case may be), such Holder (together with
such Holder’s Affiliated Parties (including shares held by any “group” of which the Holder or any of its Affiliated Parties is a member)) would have Beneficial Ownership of more than 4.99% of the total number of shares of Common Stock
then issued and outstanding (the “4.99% Ownership Limitation”); provided, that, such Holder may, at its option and upon not less than sixty-one (61) days’ prior notice to the Company, elect to increase the 4.99%
Ownership Limitation to any other percentage not in excess of 9.99% of the number of outstanding shares of Common Stock then outstanding (the “9.99% Ownership 

  
 103 








 
Limitation”). Any such increase will not be effective until the 61st day after such notice is delivered to the Company. The Company hereby covenants and agrees not to adopt any
shareholder rights plan or take any other action which would have the effect of restricting or adversely affecting the Holder’s election to change such threshold percentage.  

(g) For purposes of Sections 7.01(e) and (f) above, “Beneficial Ownership” shall mean the number of shares of
Common Stock beneficially owned by a Holder and its Affiliated Parties (and any other persons or entities acting as a “group” together with a Holder 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 which would be issuable upon (i) conversion of the remaining, unconverted portion
of the Notes beneficially owned by such Holder or any of its Affiliated Parties (and any other persons or entities acting as a “group” together with such Holder or any of such Holder’s 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 Holder or any of its Affiliated Parties (and any other persons or entities acting as a “group” together with such Holder or any of such Holder’s Affiliated Parties). Except as set forth in the preceding
sentence, for purposes of Sections 7.01(e) and (f), Beneficial Ownership shall be calculated (and, for such purpose, whether any person or entity forms a “group” with any Holder or such Holder’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 Holder that the Company is not representing to any Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and each Holder is solely
responsible for any schedules required to be filed in accordance therewith. To the extent that an ownership limitation contained in Section 7.01(f) applies, the determination of whether the Notes owned by a Holder are convertible (in
relation to other securities owned by such Holder together with its Affiliated Parties (and any other persons or entities acting as a “group” together with such Holder or any of such Holder’s Affiliated Parties)) and of which portion
of the Notes owned by such Holder is convertible shall be in the sole discretion of such Holder, and the submission of a Conversion Notice to the Conversion Agent shall be deemed to be such Holder’s determination of whether the Notes owned by
such Holder are convertible (in relation to other securities owned by such Holder together with any of its Affiliated Parties (and any other persons or entities acting as a “group” together with such Holder or any of such Holder’s
Affiliated Parties)) and of which portion of such Notes are convertible, in each case subject to the 9.99% Ownership Limitation or 4.99% Ownership Limitation, as applicable, 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.  

  
 104 








 (h) For the avoidance of doubt, if a Holder purports to convert the Principal Amount of any Notes
into shares of Common Stock hereunder and any delivery otherwise owed to such Holder hereunder is not made, in whole or in part, as a result of the 4.99% Ownership Limitation, the 9.99% Ownership Limitation or any other limitation set forth in
Sections 7.01(a), 7.01(e) or 7.09(a), then the Holder’s rights under the relevant Notes 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 Holder.

 Section 7.02 Conversion Procedure 

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

(b) In order to exercise the conversion right with respect to any interest in Global Notes, the Holder must complete the appropriate
instruction form for conversion pursuant to the Depository’s book-entry conversion program, furnish appropriate endorsements and transfer documents if required by the Company or the Trustee or Conversion Agent, and pay any transfer taxes or
duties if required pursuant to Section 7.08. However, no service charge will be imposed by the Company, the Trustee or the Registrar for any registration of transfer or exchange of Notes except in compliance with the below provisions governing
exercise of conversion rights. In order to exercise the conversion right with respect to any Physical Notes, the Holder of any such Notes to be converted, in whole or in part, shall: 

(i) complete and manually sign the conversion notice provided on the back of the Note (the “Conversion
Notice”) or facsimile of the Conversion Notice and deliver such notice to a Conversion Agent, which action shall be irrevocable; 

(ii) surrender the Note to the Conversion Agent; 

(iii) if required, furnish appropriate endorsements and transfer documents; and 

(iv) if required pursuant to Section 7.08, pay any transfer taxes or duties. 

The date on which the Holder satisfies all of the applicable requirements set forth above is the “Conversion Date.” 

(c) On the third Business Day immediately following the Conversion Date, the Company shall issue and shall deliver to the converting Holder at
the office of the Conversion Agent, a certificate or certificates for the number of full shares of Common Stock issuable in respect of such conversion in accordance with the provisions of this Article 7. In case any Notes of a denomination greater
than $1,000 shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of the Notes so surrendered, without charge to such Holder, new Notes in authorized denominations in an
aggregate Principal Amount equal to the unconverted portion of the surrendered Notes. 
 Each conversion shall be deemed to have been
effected as to any such Notes (or portion thereof) on the date on which the requirements set forth above in Section 7.02(b) have been satisfied as to such Notes (or portion thereof) and the Person in whose name any certificate or certificates
for shares of Common Stock shall be issuable upon such conversion shall be deemed to have become, as of the Close of Business on the relevant Conversion Date that such Holder converted the Notes, the holder of record of the shares of Common Stock
represented thereby. 

  
 105 








 (d) Upon the conversion of an interest in a Global Note, the Trustee (or other Conversion Agent
appointed by the Company) 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 conversions of Notes effected through any Conversion Agent
other than the Trustee. 
 (e) Each share certificate representing Common Stock issued upon conversion of the Notes that are Restricted
Notes shall bear the Restricted Stock Legend as set forth in Section 3.07 and Exhibit A. 
 Section 7.03 Settlement upon
Conversion 
 (a) With respect to any conversion of Notes, if any, the Company shall, subject to the provisions of this Article 7,
deliver to converting Holders, in respect of the Principal Amount of Notes being converted, a number of shares of Common Stock equal to the Applicable Conversion Rate, on the third Business Day immediately following the relevant Conversion Date,
together with any applicable Make-Whole Payment in cash or in shares of Common Stock, as applicable, and cash in lieu of any fractional shares of Common Stock pursuant to Section 7.03(d). 

(b) Upon conversion, Holders shall not receive any separate cash payment for accrued and unpaid interest unless such conversion occurs between
a Regular Record Date and the Interest Payment Date to which it relates and the converting Holder was the Holder on the relevant Regular Record Date. 

(c) If Notes are converted after the Close of Business on a Regular Record Date for the payment of interest, Holders of such Notes at the
Close of Business on such Regular Record Date will receive the interest payable on such Notes on the corresponding Interest Payment Date (including any outstanding PIK Interest) notwithstanding the conversion. 

(d) The Company shall not issue fractional shares upon conversion of Notes (and on payment of any Make-Whole Payment in shares of Common
Stock, as applicable). If multiple Notes shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issuable upon conversion (and on payment of any Make-Whole Payment in shares of Common Stock, as
applicable) (and the number of fractional shares, 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
(and the aggregate Make-Whole Payment to be paid in shares of Common Stock, if applicable). If any fractional share would be issuable upon the conversion of any Notes (and on payment of any Make-Whole Payment in shares of Common Stock, as
applicable), the Company shall make payment of an amount in cash for the current market value of the fractional shares. 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. 

  
 106 








 (e) By delivery to the Holder of the full number of shares of Common Stock, together with any
applicable Make-Whole Payment in cash or in shares of Common Stock, as applicable, and any cash payment for fractional shares, issuable upon conversion, the Company will be deemed to satisfy in full its obligation to pay the Principal Amount of the
Notes so converted, the applicable Make-Whole Payment, as applicable, and all accrued and unpaid interest to, but excluding, the Conversion Date. 

(f) If and only if the Company obtains Stockholder Approval of the 19.99% Proposal, in addition to the consideration due upon conversion as
provided herein, each Holder who elects to convert any of its Notes at the Holder’s option will receive a payment (the “Voluntary Conversion Make-Whole Payment”) for the Notes being converted. The Voluntary Conversion
Make-Whole Payment will be an amount equal to the aggregate amount of interest payments that would have been payable on such converted Notes from the last day through which interest was paid on the Notes (or from the Issue Date if no interest has
been paid on the Notes or from the next succeeding Interest Payment Date if such conversion occurs after a Regular Record Date and on or before the next succeeding Interest Payment Date), through and including the Maturity Date (determined as if
such conversion did not occur). If the Company obtains Stockholder Approval of the Stockholder Proposals, the Company may settle the Voluntary Conversion Make-Whole Payment in cash or in shares of Common Stock, at the Company’s election,
subject to the limitations described in Sections 7.01(e) and (f) and in Section 7.09(a). A Holder shall have the right prior to settlement to notify the Company that any proposed settlement of the Voluntary Conversion Make-Whole Payment in
shares of Common Stock would violate such limitations. To the extent that such limitations apply, the number of shares of Common Stock issuable upon conversion (and the associated Principal Amount of the Notes being converted) and in settlement of
the Voluntary Conversion Make-Whole Payment shall be reduced proportionately so that the total number of shares issuable upon and after giving effect to such conversion and in settlement of the Voluntary Conversion Make-Whole Payment in shares of
Common Stock shall not exceed such limitations. In the event that the foregoing structure should in any way adversely affect the Company’s ability to comply with the applicable rules and regulations of the NASDAQ Stock Market, LLC for purposes
of obtaining Stockholder Approval of the 19.99% Proposal, the Company will not have the right to elect to pay the Voluntary Conversion Make-Whole Payment in shares of Common Stock, and all Voluntary Conversion Make-Whole Payments shall be paid in
cash. Subject to the foregoing, if the Company elects to pay the Voluntary Conversion Make-Whole Payment in shares of Common Stock, the Company will deliver to each Holder of converted Notes a number of shares of Common Stock at settlement equal to
(i) the amount of the Voluntary Conversion Make-Whole Payment owed to such Holder and being paid in shares of Common Stock divided by (ii) the applicable Conversion Price. Delivery of such shares of Common Stock shall be made in the same
manner as the delivery of shares in settlement of the conversion obligation under this Article 7. If the Company elects or, due to the limitations set forth herein, is obligated to pay the Voluntary Conversion Make-Whole Payment in cash, the Company
shall, on the third Business Day immediately following the relevant Conversion Date, deposit with the Paying Agent a sum (in funds which are immediately available on the due date for such payment) sufficient to pay such Voluntary Conversion
Make-Whole Payment, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action. Within two (2) Business Days immediately following the Conversion Date, the Company shall send,
or at the written request and expense of the Company have the Trustee send, a notice to the Holders 

  
 107 








 
specifying whether the Company has elected to settle the Voluntary Conversion Make-Whole Payment in cash or in shares of Common Stock (the “Voluntary Conversion Make-Whole Payment
Notice”). If the Company gives the Voluntary Conversion Make-Whole Payment Notice, it shall also deliver a copy of such notice to the Trustee and Paying Agent. With respect to Physical Notes, such delivery shall be by first class mail, and
with respect to Global Notes, such delivery shall be pursuant to the Applicable Procedures of the Depository. 
 Section 7.04
Adjustment of Conversion Rate 
 The Applicable Conversion Rate shall be adjusted from time to time by the Company if any of the
following events occurs as described below, except that the Company will not make any adjustment to the Conversion Rate if Holders of Notes participate (other than in the case of a share split or share combination), at the same time and on the same
terms as holders of shares of Common Stock, solely as a result of holding the Notes, in any of the transactions described in this Section 7.04, without having to convert their Notes, as if such Holders held a number of shares of Common Stock
equal to the Applicable Conversion Rate in effect immediately prior to the adjustment thereof in respect of such transaction, multiplied by the Principal Amount of Notes held by such Holders. 

(a) If the Company issues shares of Common Stock as a dividend or distribution on the Common Stock, or if the Company effects a share split or
share combination of its Common Stock, the Applicable Conversion Rate will be adjusted based on the following formula: 
  

							
		  	CR1 = CR0 x	  	 OS1

 
	  	
		  	  	  

OS0
	  	

 where, 
  

			
		
	CR0 =	  	the Applicable Conversion Rate in effect immediately prior to the Close of Business on the Record Date for 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;
		
	CR1 =	  	the Applicable Conversion Rate in effect immediately after the Close of Business on such Record Date or immediately after the Open of Business on such effective date, as applicable;
		
	OS0 =	  	the number of shares of Common Stock outstanding immediately prior to the Close of Business on such Record Date or immediately prior to the Open of Business on such effective date, as applicable; and
		
	OS1 =	  	 the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share
combination.




  
 108 








 Any adjustment made pursuant to this Section 7.04(a) shall become effective immediately
after the Close of Business on the Record 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 7.04(a) is declared but not so paid or made, or any such share split or combination is announced but the outstanding shares of Common Stock are not split or combined, as the case may be, the Applicable Conversion Rate
shall be immediately readjusted, effective as of the date the Company’s Board of Directors determines not to pay such dividend or distribution, or not to split or combine the outstanding shares of Common Stock, as the case may be, to the
Conversion Rate that would then be in effect if such dividend, distribution, share split or share combination had not been declared or announced. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in
the Applicable Conversion Rate, no adjustment to the Applicable Conversion 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
Applicable Conversion Rate as described in the immediately preceding sentence). 
 (b) If the Company distributes to all or substantially
all holders of shares of Common Stock any rights, options or warrants entitling them for a period of not more than sixty (60) calendar days after the date of such distribution to subscribe for or purchase shares of Common Stock, at a price per
share less than the average of the Last Reported Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of such distribution, the Applicable
Conversion Rate will be increased based on the following formula: 
  

							
		 	 CR1 = CR0 x
	  	 OS0 + X

 
	  	
		 	  	  

OS0 + Y
	  	

 where, 
  

			
		
	CR0 =	  	the Applicable Conversion Rate in effect immediately prior to the Close of Business on the Record Date for such distribution;
		
	CR1 =	  	the Applicable Conversion Rate in effect immediately after the Close of Business on such Record Date;
		
	OS0 =	  	the number of shares of Common Stock outstanding immediately prior to the Close of Business on such Record 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 ten
(10) consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the distribution of such rights, options or warrants.



  
 109 








 The foregoing increase in the Applicable Conversion Rate shall be successively made whenever any
such rights, options or warrants are distributed and shall become effective immediately after the Close of Business on the Record Date for such distribution. If such rights, options or warrants are not so distributed, the Applicable Conversion Rate
will be immediately decreased to the Conversion Rate that would then be in effect if such Record Date for such distribution had not been fixed. In addition, to the extent that shares of Common Stock are not delivered after the expiration of such
rights, options or warrants, the Applicable Conversion Rate shall be immediately decreased to the Conversion Rate that would then be in effect had the increase made for the distribution of such rights, options or warrants been made on the basis of
delivery of only the number of shares of Common Stock actually delivered. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the Applicable 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 two immediately preceding sentences). 

In determining whether any rights, options or warrants entitle the holders of shares of Common Stock to subscribe for or purchase or exercise
conversion rights for, shares of Common Stock at a purchase price less than such average of the Last Reported Sale Prices of Common Stock over the ten (10) consecutive Trading Day period ending on, and including, the Trading Day immediately
preceding the date of announcement of such distribution, and in determining the aggregate exercise or purchase price payable for 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 upon exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Company’s 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 (the “Distributed Property”), to all or substantially all holders of shares of Common Stock, excluding: 

(i) dividends or distributions of Common Stock or rights, options or warrants as to which an adjustment was effected pursuant
to Section 7.04(a) or Section 7.04(b), as the case may be; 
 (ii) dividends or distributions paid exclusively in
cash as to which an adjustment was effected pursuant to Section 7.04(d); and 
 (iii) Spin-Offs to which the provisions
set forth below in this Section 7.04(c) apply; 

  
 110 








 then the Applicable Conversion Rate will be increased based on the following formula: 

 

							
		 	CR1 = CR0 x	  	 SP0

 
	  	
		 		  	  

SP0 - FMV
	  	

 where, 
  

			
		
	CR0 =	  	the Applicable Conversion Rate in effect immediately prior to the Close of Business on the Record Date for such distribution;
		
	CR1 =	  	the Applicable Conversion Rate in effect immediately after the Close of Business on such Record Date;
		
	SP0 =	  	the average of the Last Reported Sale Prices of the Common Stock over the ten (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 Company’s Board of Directors) of the Distributed Property distributed with respect to each outstanding share of Common Stock on the Ex-Dividend Date for such distribution;


 provided that if “FMV” as set forth above is equal to or greater than “SP0” as set forth above, in lieu of the foregoing increase, adequate provision will be made so that each Holder of a Note shall receive on the date on which the Distributed Property is
distributed to holders of the Common Stock, for the Principal Amount of the Notes, the amount and kind of Distributed Property that such Holder would have received had such Holder owned a number of shares of Common Stock equal to the Applicable
Conversion Rate on the Record Date for such distribution; provided further that if the Company’s Board of Directors determines “FMV” for purposes of the foregoing increase by reference to the actual or when-issued trading
market for any securities, it must in doing so consider the prices in such market over the same period used in computing the average of the Last Reported Sale Prices of the Common Stock for purposes of determining “SP0” as set forth above. 
 An increase in the Applicable Conversion Rate made
pursuant to the immediately preceding paragraph shall become effective immediately after the Close of Business on the Record Date for such distribution. If such distribution is declared but not so paid or made, the Applicable Conversion Rate shall
be decreased to be the Conversion Rate that would then be in effect if such distribution had not been declared. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the Applicable 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 immediately preceding sentence).

 With respect to an adjustment pursuant to this Section 7.04(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 or affiliate, of the Company, where such Capital
Stock or similar equity interest is listed or quoted (or will be listed or quoted upon consummation of the Spin-Off) on The New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors) (a
“Spin-Off”), the Applicable Conversion Rate will be increased based on the following formula: 
  

							
		 	CR1 = CR0 x	  	 FMV0 + MP0

 
	  	
		 		  	  

MP0
	  	

 where, 
  

			
		
	CR0 =	  	the Applicable Conversion Rate in effect immediately prior to the end of the Valuation Period;
		
	CR1 =	  	the Applicable 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 shares of Common Stock applicable to one share of Common Stock (determined for purposes of the definition of
“Last Reported Sale Price” as if such Capital Stock or similar equity interest were Common Stock) over the first ten consecutive Trading Day period after, and including, the effective 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 in the Applicable Conversion Rate under the immediately preceding paragraph will be
determined as of the Close of Business on the last Trading Day of the Valuation Period but will be given effect immediately after the Close of Business on the Record Date of the Spin-Off; provided that in respect of any conversion during the
Valuation Period, references with respect to ten (10) consecutive Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the effective date of such Spin-Off to, and including, the
Conversion Date in determining the Applicable Conversion Rate. If any dividend or distribution that constitutes a Spin-Off is declared but not so paid or made, the Applicable Conversion Rate shall be immediately decreased, effective as of the date
the Company’s 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 Applicable 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
immediately preceding sentence). 

  
 112 








 For purposes of this Section 7.04(c) (and subject in all respect to Section 7.12),
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 Common Stock; (ii) are not exercisable; and
(iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 7.04(c) (and no adjustment to the Applicable Conversion Rate under this Section 7.04(c)
will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Applicable Conversion Rate shall be
made under this Section 7.04. If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, is 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 or property, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Record Date with
respect to new rights, 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 event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a
distribution amount for which an adjustment to the Applicable Conversion Rate under this Section 7.04(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 Applicable Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Applicable Conversion Rate shall then again be
readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share of Common Stock redemption or purchase price received by a holder or holders of
shares 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 shares 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 Applicable Conversion Rate shall be readjusted as if such rights, options and warrants had not been
issued. 
 For purposes of Section 7.04(a), Section 7.04(b) and this Section 7.04(c), any dividend or distribution to which
this Section 7.04(c) is applicable that also includes one or both of: 
 (A) a dividend or distribution of shares of
Common Stock to which Section 7.04(a) is applicable (the “Clause A Distribution”); or 
 (B) a dividend
or distribution of rights, options or warrants to which Section 7.04(b) is applicable (the “Clause B Distribution”), 
 then
(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 7.04(c) is applicable (the “Clause C
Distribution”) and any adjustment to the Applicable Conversion Rate required by this Section 7.04(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall
be deemed to immediately 

  
 113 








 
follow the Clause C Distribution and any adjustment to the Applicable Conversion Rate required by Section 7.04(a) and Section 7.04(b) with respect thereto shall then be made, except
that, if determined by the Company (I) the “Record Date” for the Clause A Distribution and the Clause B Distribution shall be deemed to be the Record Date for 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 Close of Business on such Record Date or immediately prior to the Open of Business on such effective date, as applicable”
within the meaning of Section 7.04(a) or “outstanding immediately prior to the Close of Business on such Record Date” within the meaning of Section 7.04(b). 

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

							
		  	CR1 = CR0 x	  	 SP0

 
	  	
		  	  	  

SP0 - C
	  	

 where, 
  

			
	CR0 =	  	the Applicable Conversion Rate in effect immediately prior to the Close of Business on the Record Date for such dividend or distribution;
		
	CR1 =	  	the Applicable Conversion Rate in effect immediately after the Close of Business on the Record Date for such dividend or distribution;
		
	SP0 =	  	the average of the Last Reported Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period ending on, and including, 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 holders of shares of Common Stock.


 The increase in the Conversion Rate under this Section 7.04(d) will become effective immediately
after the Close of Business on the Record Date for such dividend or distribution. If such dividend or distribution is declared but not so paid or made, the Applicable Conversion Rate shall be immediately decreased 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 Applicable 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 immediately preceding sentence). 

  
 114 








 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 the Principal Amount of Notes, at the same time and upon the same terms as
holders of shares of 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 in effect on the Record Date for such dividend or distribution. 

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for shares of Common Stock
(excluding odd lots of shares of Common Stock), to the extent that the cash and fair market value of any other consideration included in the payment per share of Common Stock exceeds the average of the Last Reported Sale Prices of the Common Stock
over the ten (10) consecutive Trading Day period immediately following, and including, the Trading Day next succeeding the last date (the “Expiration Date”) on which tenders or exchanges may be made pursuant to such tender
offer or exchange offer, the Applicable Conversion Rate will be increased based on the following formula: 
  

							
		 	CR1 = CR0 x	  	 AC + (SP1 x OS1)
  
	  	
	 	  	  

OS0 x SP1
	  	

 where 
  

			
		
	CR0 =	  	the Applicable Conversion Rate in effect immediately prior to the Close of Business on the Trading Day next succeeding the Expiration Date;
		
	CR1 =	  	the Applicable Conversion Rate in effect immediately after the Close of Business on the Trading Day next succeeding the Expiration Date;
		
	AC =	  	the aggregate fair market value of all cash and any other consideration (as determined by the Company’s Board of Directors) paid or payable for shares of Common Stock purchased in such tender offer or exchange offer;
		
	OS0 =	  	the number of shares of Common Stock outstanding immediately prior to the Expiration Date (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender offer or exchange
offer);
		
	OS1 =	  	the number of shares of Common Stock outstanding immediately after the Expiration Date (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender offer or exchange offer);
and
		
	SP1 =	  	the average of the Last Reported Sale Prices of Common Stock over the ten (10) consecutive Trading Day period immediately following, and including, the Trading Day next succeeding the Expiration Date.



  
 115 








 The increase in the Applicable Conversion Rate under this Section 7.04(e) shall occur at the
Close of Business on the 10th Trading Day immediately following the Trading Day next succeeding the Expiration Date but will be given effect immediately after the Close of Business on the Expiration Date; provided that in respect of any
conversion within the 10 consecutive Trading Day period immediately following, and including, the Expiration Date, references to 10 consecutive Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and
including, the Expiration Date to, and including, the Conversion Date in determining the Applicable Conversion Rate. 
 If the Company is
obligated to purchase shares of Common Stock pursuant to any such tender offer or exchange offer, but the Company is ultimately prevented by applicable law from effecting all or any portion of such purchases or all such purchases are rescinded, the
Applicable Conversion Rate shall immediately be readjusted 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 Applicable Conversion Rate, no adjustment to the Applicable 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) [Reserved] 

(g) In addition to those Conversion Rate adjustments required by Sections 7.04(a), 7.04(b), 7.04(c), 7.04(d) and 7.04(e), and to the extent
permitted by applicable law and subject to the applicable rules of NASDAQ Stock Market, LLC and, if applicable, any other securities exchange on which the Company’s securities are then listed, the Company from time to time (i) may increase
the Conversion Rate by any amount for a period of at least twenty (20) Business Days if the Company’s Board of Directors determines that such increase would be in the Company’s best interest and (ii) may also (but is not required
to) increase the Conversion Rate to avoid or diminish any income tax to holders of shares of Common Stock or rights to purchase shares of Common Stock in connection with any 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 this Section 7.04(g), the Company shall mail to Holders of record of the Notes a notice of the increase (in lieu of any notice otherwise required
under Section 7.04(j) below) at least five (5) 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. 

(h) The Applicable Conversion Rate will not be adjusted, among other things: 

(i) upon the issuance of any shares of Common Stock pursuant to any 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; 

  
 116 








 (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 or director benefit plan or program of the Company, or assumed by the Company, or any of the Company’s Subsidiaries; 

(iii) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or
convertible security not described in clause (ii) above and outstanding as of the date the Notes were first issued, except as set forth in Section 7.12; 

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

(v) for accrued and unpaid interest, and Additional Interest, if any. 

(i) Adjustments to the Applicable Conversion Rate under this Article 7 shall be calculated to the nearest cent or to the nearest one-ten
thousandth (1/10,000th) of a share of Common Stock. No adjustment shall be made to the Conversion Rate unless such adjustment would require a change of at least 1% in the Applicable Conversion Rate. Any adjustment that would otherwise be
required to be made shall be carried forward and taken into account in any future adjustment. Notwithstanding the foregoing, upon any conversion of the Notes (solely with respect to the Notes to be converted), the Company shall give effect to all
adjustments that Company otherwise has deferred pursuant to the immediately preceding sentence, and those adjustments will no longer be carried forward and taken into account in any future adjustment. 

(j) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any Conversion Agent 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 Trust 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 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 became effective and shall mail such notice of such adjustment of the
Conversion Rate to each Holder at such Holder’s latest address appearing in the Register, within twenty (20) days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

 (k) In any case in which this Section 7.04 provides that an adjustment shall become effective immediately after a Record Date for an
event, the Company may defer until the occurrence of such event (i) issuing to the Holder of any Notes converted after such Record Date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion
by reason of the adjustment required by such event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment and (ii) paying to such Holder any amount in cash in lieu of any fraction pursuant to
Section 7.03. 

  
 117 








 (l) For purposes of this Section 7.04, the number of shares of Common Stock at any time
outstanding shall not include shares 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 issuable in
respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 
 Section 7.05 Effect of Reclassification,
Consolidation, Merger or Sale 
 In the case of (a) any recapitalization, reclassification or change of the Common Stock (other than
changes resulting from a subdivision or combination), (b) any consolidation, merger or combination involving the Company, (c) any sale, lease or other transfer to a third party of all or substantially all of the consolidated assets of the
Company and its Subsidiaries, or (d) 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 the Merger Event, the Company shall execute with the Trustee a supplemental indenture permitted under Section 14.01 providing for the right
to convert the 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”) upon such Merger Event. If such Merger Event causes the Common Stock to be converted into the right to
receive more than a single type of consideration (determined based in part upon any form of shareholder election), the Reference Property into which the Notes will be convertible will be deemed to be the weighted average of the types and amounts of
consideration received by the holders of shares of Common Stock that affirmatively make such an election. The Company shall notify Holders of the Notes of such weighted average as soon as practicable after such determination is made. The Company
shall not become a party to any Merger Event unless its terms are consistent with the foregoing. For the avoidance of doubt, adjustments to the Conversion Rate pursuant to Section 7.04 do not apply to distributions to the extent that the right
to convert the Notes has been changed into the right to convert into, or exchange for, Reference Property. 
 The Company shall cause notice
of the execution of such supplemental indenture to be mailed to each Holder, at the address of such Holder as it appears on the Register, within twenty (20) days after execution thereof. Failure to deliver such notice shall not affect the
legality or validity of such supplemental indenture. The above provisions of this Section shall similarly apply to successive reclassifications, changes, consolidations, mergers, combinations, sales and conveyances. If this Section 7.05 applies
to any event or occurrence, Section 7.04 shall not apply. 
 Section 7.06 Adjustments of Prices 

Whenever any provision of this Indenture requires a calculation of the Last Reported Sale Prices over a span of multiple days, the Company will
make appropriate adjustments determined by the Company or its agents to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Record Date,
effective date or expiration date, as the case may be, of the event occurs, at any time during the period during which such prices are to be calculated. Such adjustments will be effective as of the Ex-Dividend Date, Record Date, effective date or
expiration date, as the case may be, of the event causing the adjustment to the Conversion Rate. 

  
 118 








 Section 7.07 Company’s Conversion Option 

(a) The Company may, from time to time, at any time during the period commencing on the later of the date the Company obtains
Stockholder Approval of the 19.99% Proposal and six (6) months after the First Issue Date and ending on the Close of Business on the Business Day immediately preceding the Maturity Date, elect to mandatorily require the Holders to convert some
or all of the Notes at the then applicable Conversion Rate, if the Last Reported Sale Price of the Common Stock over any ten (10) consecutive Trading Days during such period equals or exceeds 150% of the then applicable Conversion Price (a
“Conversion Event”) by sending, or at the written request and expense of the Company having the Trustee send, a notice (the “Conversion Event Company Notice”) within twenty (20) Trading Days of the Conversion
Event and not more than thirty (30) Trading Days but not less than ten (10) Trading Days prior to the day selected by the Company on which the Notes will be converted pursuant to the Company’s conversion option (the “Company
Conversion Date”; and the date such Company Conversion Notice is sent to the Holders in the manner herein provided, the “Company Conversion Notice Date”). If the Company gives such notice, it shall also deliver a copy of
such Company Conversion Notice to the Trustee and Paying Agent. With respect to Physical Notes, such delivery shall be by first class mail, and with respect to Global Notes, such delivery shall be pursuant to the Applicable Procedures of the
Depository.  
 Each Company Conversion Notice shall state: 

(i) the Company Conversion Notice Date; 

(ii) the aggregate principal amount of Notes to be converted; 

(iii) that the Company Conversion Notice is being made pursuant to this Section 7.07; 

(iv) the events causing the Conversion Event and the date(s) of the Conversion Event; 

(v) the Applicable Conversion Rate and any adjustments to the Applicable Conversion Rate; 

(vi) whether the Company has elected to settle the Conversion Event Make-Whole Payment (as defined below) in cash or in shares
of Common Stock; 
 (vii) the Company Conversion Date; 

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

(ix) the procedures that Holders must follow to allow the Company to convert their Notes, including the place or places where
Holders will be required to surrender the Notes. 

  
 119 








 The Company’s election of its conversion option hereunder must be made equally and proportionately
with respect to any and all Notes duly issued hereunder (or, in the case of Global Notes, pursuant to Applicable Procedures that most nearly approximate a pro rata selection), and the Last Reported Sale Price of the Common Stock must equal or exceed
150% of the then applicable Conversion Price on both the date of the Company’s election and on the Company Conversion Date. Notwithstanding the Company’s election of its conversion option hereunder, the Holders shall not be required to
convert to the extent such conversion would result in such Holders receiving more than 2,000,000 shares of Common Stock in any three (3) month period, and such conversion shall be subject to the limitations described in Sections 7.01(e) and
(f) and in Section 7.09(a). In connection with the Company’s exercise of its conversion option under this Section 7.07, the Holders will receive upon conversion, in addition to and concurrently with the other consideration
payable upon conversion under this Article 7, a payment (the “Conversion Event Make-Whole Payment”) for the Notes being converted in an amount equal to the aggregate amount of interest payments that would have been payable on such
converted Notes from the last day through which interest was paid on the Notes (or from the Issue Date if no interest has been paid on the Notes or from the next succeeding Interest Payment Date if such conversion occurs after a Regular Record Date
and on or before the next succeeding Interest Payment Date), through and including the Maturity Date (determined as if such conversion did not occur).  

(b) The Company may settle the Conversion Event Make-Whole Payment in cash or in shares of Common Stock, at the Company’s election,
subject to the limitations described in Sections 7.01(e) and (f) and in Section 7.09(a). A Holder shall have the right prior to settlement to notify the Company that any proposed settlement of the Conversion Event Make-Whole Payment in
shares of Common Stock would violate such limitations. Notwithstanding the foregoing, in the event that the foregoing structure should in any way adversely affect the Company’s ability to comply with the applicable rules and regulations of the
NASDAQ Stock Market, LLC for purposes of obtaining Stockholder Approval of the 19.99% Proposal, the Company will not have the right to elect to pay the Conversion Event Make-Whole Payment in shares of Common Stock, and all Conversion Event
Make-Whole Payments shall be paid in cash. Subject to the foregoing, if the Company elects to pay the Conversion Event Make-Whole Payment in shares of Common Stock, the Company will deliver to each Holder of converted Notes a number of shares of
Common Stock at settlement equal to (i) the amount of the Conversion Event Make-Whole Payment owed to such Holder and being paid in shares of Common Stock divided by (ii) the applicable Conversion Price. Delivery of such shares of Common
Stock shall be made in the same manner as the delivery of shares in settlement of the conversion obligation under this Article 7. If the Company elects or, due to the limitations set forth herein, is obligated to pay the Conversion Event Make-Whole
Payment in cash, the Company shall, on the third Business Day immediately following the relevant Company Conversion Date, deposit with the Paying Agent a sum (in funds which are immediately available on the due date for such payment) sufficient to
pay such Conversion Event Make-Whole Payment, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action. 

(c) Notwithstanding the foregoing, the Company shall not be entitled to exercise its conversion option under Sections 7.07(a) and
(b) hereof if (i) an Event of Default has occurred and is continuing, (ii) a Filing Failure, Effectiveness Failure or Maintenance Failure (as such 

  
 120 








 
terms are defined in the Registration Rights Agreement) or other event has occurred as a result of which sales of all of the shares of Common Stock to be issued under Sections 7.07(a) and
(b) hereof cannot be made under an effective registration statement, (iii) the Company has not listed or caused to have quoted all of the shares of Common Stock to be issued under Section 7.07(a) and (b) hereof on the NASDAQ
Stock Market, LLC and/or each national securities exchange or over-the-counter or other domestic market on which the Common Stock is then listed or quoted, (iv) such exercise (which, for the avoidance of doubt, includes any related Make-Whole
Payment) would otherwise violate Sections 7.01(e), 7.01(f) and 7.09(a) of this Indenture or the listing requirements or other rules or regulations of the NASDAQ Stock Market, LLC and/or each national securities exchange or over-the-counter or other
domestic market on which the Common Stock is then listed or quoted, or (v) the Company shall not have obtained Stockholder Approval of the 19.99% Proposal. 

Section 7.08 Taxes on Shares Issued 

Any issue of share certificates on conversions of Notes shall be made without charge to the converting Holder for any documentary, transfer,
stamp or any similar tax in respect of the issue thereof, and the Company shall pay any and all documentary, stamp or similar issue or transfer taxes or duties that may be payable in respect of the issue or delivery of shares of Common Stock on
conversion of Notes pursuant hereto. The Company shall not, however, be required to pay any such tax which may be payable in respect of any transfer involved in the issue and delivery of shares in any name other than that of the Holder of any Notes
converted, and the Company shall not be required to issue or deliver any such share certificate unless and until the Person or Persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to
the satisfaction of the Company that such tax has been paid. 
 Section 7.09 Reservation of Shares; Shares to be Fully Paid;
Compliance with Governmental Requirements 
 (a) Notwithstanding any other provision of this Indenture to the contrary, prior to the
Company obtaining Stockholder Approval for the Authorized Shares Proposal, no Holder will convert, and the Company may not require a Holder to convert pursuant to Section 7.07, such portion of the Principal Amount of any Notes into shares of
Common Stock, if and to the extent that the Company does not have a sufficient number of shares of Common Stock authorized but unissued to effect the issuance of the shares of Common Stock deliverable pursuant to such conversion; and provided
further, that the Company shall not be allowed to elect to pay all or any portion of any Make-Whole Payment in shares of Common Stock to the extent that after the issuance of the shares of Common Stock deliverable pursuant to such conversion the
Company would not have a sufficient number of shares of Common Stock authorized but unissued to effect the issuance of the shares of Common Stock to make such Make-Whole Payment in shares of Common Stock. 

(b) Upon the issuance of any Notes, including PIK Notes, and upon any adjustment to the Conversion Price, the Company shall reserve, if
necessary, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock, to provide for the conversion of the Notes, subject to the limitations set forth in


  
 121 








 
Sections 7.01(e) and (f) and shall not issue such shares as are so reserved for any other purpose except to the extent that the Notes are otherwise retired pursuant to the terms of this
Indenture; provided, however, that if prior to obtaining Stockholder Approval for the Authorized Shares Proposal, the Company does not have a sufficient number of shares of Common Stock authorized for such purpose, it shall so notify the Trustee and
the number of shares of Common Stock reserved for such issuance shall be limited to the number of shares of Common Stock legally available therefor. 

(c) Before taking any action that would cause an adjustment increasing the Conversion Rate to an amount that would cause the Conversion Price
to be reduced below the then par value, if any, of the shares of Common Stock issuable upon conversion of the Notes, the Company will take all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may
validly and legally issue shares of such shares of Common Stock at such adjusted Conversion Price. 
 (d) Subject to the Sections 7.09(a)
and (b) above, the Company covenants that all shares of Common Stock that may be issued upon conversion of Notes or in settlement of a Make-Whole Payment in shares of Common Stock shall be newly issued shares or treasury shares, shall be duly
authorized, validly issued, fully paid and non-assessable and shall be free from preemptive rights and free from any lien or adverse claim. 

Section 7.10 Responsibility of Trustee and Conversion Agent 

The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine the Conversion
Rate or whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any
supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any Common Stock, or of any securities or
property, which may at any time be issued or delivered upon the conversion of any Notes; 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 share certificates or other securities or property or cash upon the surrender of any Notes for the purpose of conversion or to comply with any of the duties,
responsibilities or covenants of the Company contained in this Article 7. 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 7.05 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any
event referred to in such Section 7.05 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 11.01, may accept as conclusive evidence of the correctness of any such provisions, and shall be
protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. 

  
 122 








 Section 7.11 Notice to Holders Prior to Certain Actions 

In case: 
 (a) the Company shall
declare a dividend (or any other distribution) on Common Stock that would require an adjustment in the Conversion Rate pursuant to Section 7.04; or 

(b) the Company shall authorize the granting to the holders of all or substantially all of the shares of Common Stock of options, rights or
warrants to subscribe for or purchase any share of any class or any other options, rights or warrants; or 
 (c) of any reclassification or

the Company is a party and for which approval of any shareholders of the Company is required, or of the sale, lease or transfer of all or substantially all of the assets of the Company; or 

(d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company or any Significant Subsidiary that is a Credit

such reclassification, reorganization, consolidation, merger, sale, lease, transfer, dissolution, liquidation or winding up is expected to become effective or occur, and the date as of which it is expected that holders of shares of Common Stock of
record shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such reclassification, reorganization, consolidation, merger, sale, transfer, dissolution, liquidation or winding up. Failure to give
such notice, or any defect therein, shall not affect the legality or validity of such dividend, distribution, reclassification, reorganization, consolidation, merger, sale, transfer, dissolution, liquidation or winding up.

PURCHASE AT OPTION OF HOLDERS UPON A FUNDAMENTAL CHANGE 

Section 8.01 Purchase at Option of Holders upon a Fundamental Change 

(a) Generally. If a Fundamental Change occurs at any time prior to the Maturity Date of the Notes, then each Holder shall have
the right, at such Holder’s option to require the Company to purchase any or all of such Holder’s Notes, on a date specified by the Company that is no earlier than the 20th and not later than the 35th calendar day following the date of the
Fundamental Change Company Notice, subject to extension to comply with applicable law (the “Fundamental Change Purchase Date”), at a purchase price (the “Fundamental Change Purchase Price”) in cash equal to
(i) 100% of the Principal Amount thereof, plus (ii) accrued and unpaid interest thereon to, but excluding, the Fundamental Change Purchase Date (provided, however, that if the Fundamental Change Purchase Date occurs after a Regular Record
Date and on or prior to the Interest Payment Date to which it relates, the Company will pay accrued and unpaid interest to the Holder of record on such Regular Record Date) or, in the case of a Default by the Company in the payment of the
Fundamental Change Purchase Price with respect to such Notes, the day on which such Default is no longer continuing, plus (iii) an amount (the “Fundamental Change Make-Whole Payment”) equal to the aggregate amount of interest
payments that would have been payable on such repurchased Notes from the last day through which interest was paid on the Notes (or from the Issue Date if no interest has been paid on the Notes or from the next succeeding Interest Payment Date if
such conversion occurs after a Regular Record Date and on or before the next succeeding Interest Payment Date), through but not including the Maturity Date (determined as if such repurchase did not occur). 

Purchases of Notes under this Section 8.01 shall be made, at the option of the Holder thereof upon: 

(i) delivery to the Paying Agent of a duly completed notice (the “Fundamental Change Purchase Notice”) in the
form set forth on the reverse of the Notes on or prior to the Business Day immediately preceding the Fundamental Change Purchase Date, subject to extension to comply with applicable law, which must specify: 

(A) if the Notes are Physical Notes, the certificate numbers of the Holder’s Notes to be delivered for purchase; 

(B) the portion of the Principal Amount of the Holder’s Notes to be purchased; and 

(C) that the Holder’s Notes are to be purchased by the Company pursuant to the applicable provisions of the Notes and this
Indenture; and 

  
 124 








 (ii) delivery or book-entry transfer of the Notes to the Trustee (or other Paying
Agent appointed by the Company) (together with all necessary endorsements) at any time on or prior to the Business Day immediately preceding the Fundamental Change Purchase Date, subject to extension to comply with applicable law, at the applicable
Corporate Trust Office of the Trustee (or other Paying Agent appointed by the Company), such delivery being a condition to receipt by the Holder of the Fundamental Change Purchase Price therefor; provided that such Fundamental Change Purchase Price
shall be so paid pursuant to this Section 8.01 only if the Notes so delivered to the Trustee (or other Paying Agent appointed by the Company) shall conform in all respects to the description thereof in the related Fundamental Change Purchase
Notice; provided that, if such Holder’s Notes are not Physical Notes, such Holder must comply with the Applicable Procedures. 
 Any
purchase by the Company contemplated pursuant to the provisions of this Section 8.01 shall be consummated by the delivery of the Fundamental Change Purchase Price to be received by the Holder promptly following the later of the Fundamental
Change Purchase Date or the time of the book-entry transfer or delivery of the Notes. 
 Notwithstanding anything herein to the contrary,
any Holder delivering to the Trustee (or other Paying Agent appointed by the Company) the Fundamental Change Purchase Notice contemplated by this Section 8.01 shall have the right to withdraw such Fundamental Change Purchase Notice (in whole or
in part) at any time prior to the Close of Business on (i) the Business Day prior to the Fundamental Change Purchase Date or (ii) in the case of a Default by the Company in the payment of the Fundamental Change Purchase Price with respect
to such Notes, the Business Day immediately preceding the day on which such Default is no longer continuing, in either case, by delivery of a written notice of withdrawal to the Trustee (or other Paying Agent appointed by the Company) in accordance
with Section 8.03 below. 
 The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Purchase
Notice or written notice of withdrawal thereof. 
 (b) Fundamental Change Company Notice. On or before the 20th day after the
occurrence of a Fundamental Change, the Company shall provide to all Holders of record of the Notes and the Trustee and Paying Agent a notice (the “Fundamental Change Company Notice”) of the occurrence of such Fundamental Change and
of the purchase right at the option of the Holders arising as a result thereof (a “Fundamental Change Offer”). With respect to Physical Notes, such delivery shall be by first class mail, and with respect to Global Notes, such
delivery shall be pursuant to the Applicable Procedures of the Depository. Simultaneously with providing such Fundamental Change Company Notice, the Company shall publish such information on the Company’s website or through such other public
medium as the Company may use at such time. 
 Each Fundamental Change Company Notice shall state: 

(i) that the Fundamental Change Company Notice is being made pursuant to this Section 8.01 and that all Notes tendered
will be accepted for payment; 

  
 125 








 (ii) the events causing the Fundamental Change; 

(iii) the date of the Fundamental Change; 

(iv) the last date on which a Holder may exercise the purchase right or withdraw their election; 

(v) the Fundamental Change Purchase Price; 

(vi) the Fundamental Change Purchase Date; 

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

(viii) if applicable, the Applicable Conversion Rate and any adjustments to the Applicable Conversion Rate; 

(ix) if applicable, that the Notes with respect to which a Fundamental Change Purchase Notice has been delivered by a Holder
may be converted only if the Holder withdraws the Fundamental Change Purchase Notice in accordance with Section 8.03; 

(x) that any Note not tendered will continue to accrue interest in accordance with the terms of this Indenture; 

(xi) the procedures that Holders must follow to require the Company to purchase their Notes, including that Holders electing to
have any Notes purchased will be required to surrender the Notes; and 
 (xii) that Holders whose Notes are being purchased
only in part will be issued new Notes equal in Principal Amount to the unpurchased portion of the Notes surrendered. 
 No failure of the
Company to give the foregoing notices and no defect therein shall limit any Holder’s rights or affect the validity of the proceedings for the purchase of the Notes pursuant to this Section 8.01. 

Notwithstanding anything to the contrary in this Section 8.01 the Company will not be required to make a Fundamental Change Offer upon a
Fundamental Change if a third party makes the Fundamental Change Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 8.01 and purchases all Notes properly tendered and not withdrawn
under the Fundamental Change Offer (it being understood that such third-party may make a Fundamental Change Offer that is conditioned upon and prior to the occurrence of a Fundamental Change). 

Notwithstanding anything to the contrary contained herein, a Fundamental Change Offer may be made in advance of a Fundamental Change,
conditioned upon the consummation of such Fundamental Change, if a definitive agreement is in place for the Fundamental Change at the time the Fundamental Change Offer is made. 

  
 126 








 (c) No Payment During an Acceleration. Notwithstanding the foregoing, no Notes may be
purchased by the Company at the option of the Holders pursuant to this Section 8.01 if the Principal Amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Fundamental Change Purchase Date
(except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Purchase Price with respect to such Notes). 

(d) Payment of Fundamental Change Purchase Price. The Notes to be purchased pursuant to this Section 8.01, as well as the
Fundamental Change Make-Whole Payment, shall be paid for in cash. 
 Section 8.02 Effect of Fundamental Change Purchase Notice

 Upon receipt by the Paying Agent of the Fundamental Change Purchase Notice specified in Section 8.01(a), the Holder of the Note in
respect of which such Fundamental Change Purchase Notice was given shall (unless such Fundamental Change Purchase Notice is withdrawn as specified in Section 8.03) thereafter be entitled to receive solely the Fundamental Change Purchase Price
with respect to such Note. Such Fundamental Change Purchase Price shall be payable to such Holder promptly following the later of (a) the Fundamental Change Purchase Date with respect to such Note (provided the conditions in
Section 8.01(a) have been satisfied) and (b) the time of delivery or book-entry transfer of such Note to the Paying Agent by the Holder thereof in the manner required by Section 8.01(a). 

Section 8.03 Withdrawal of Fundamental Change Purchase Notice 

(a) A Fundamental Change Purchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the
Paying Agent in accordance with the Fundamental Change Company Notice prior to the Close of Business on (i) the Business Day immediately preceding the relevant Fundamental Change Purchase Date or (ii) in the case of a Default by the
Company in the payment of the Fundamental Change Purchase Price with respect to such Notes, the Business Day immediately preceding the day on which such Default is no longer continuing, specifying: 

(A) the Principal Amount of the withdrawn Notes; 

(B) if the Notes are Physical Notes, the certificate numbers of the withdrawn Notes; and 

(C) the Principal Amount, if any, of such Notes that remains subject to the original Fundamental Change Purchase Notice; 

provided that, if such Holder’s Notes are not Physical Notes, such Holder must comply with the Applicable Procedures. 

  
 127 








 Section 8.04 Deposit of Fundamental Change Purchase Price 

Prior to 11:00 a.m. (local time in The City of New York) on the Fundamental Change Purchase Date, the Company shall deposit with the Paying
Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided herein) an amount of money (in immediately available funds if deposited on such Business Day)
sufficient to pay the Fundamental Change Purchase Price, of all the Notes or portions thereof properly tendered pursuant to the Fundamental Change Purchase Notice that are to be purchased as of the Fundamental Change Purchase Date. The Company shall
promptly notify the Trustee in writing of the amount of any deposits of cash made pursuant to this Section 8.04. If the Paying Agent holds money sufficient to pay the Fundamental Change Purchase Price of any Note surrendered for purchase and
not withdrawn in accordance with this Indenture as of the Close of Business on the Fundamental Change Purchase Date, then immediately following the Close of Business on the Fundamental Change Purchase Date, (a) any such Note will cease to be
outstanding and interest will cease to accrue thereon on the Fundamental Change Purchase Date (whether or not book-entry transfer of the Notes is made or whether or not the Notes are delivered to the Paying Agent) and (b) all other rights of
the Holder in respect thereof will terminate (other than the right to receive the Fundamental Change Purchase Price and previously accrued and unpaid interest (including Additional Interest, if any) upon delivery or book-entry transfer of such
Note). 
 Section 8.05 Notes Purchased in Whole or in Part 

Any Note that is to be purchased, whether in whole or in part, shall be surrendered at the office of the Paying Agent (with, if the Company or
the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing) and the Company
shall execute and the Trustee shall authenticate and deliver to the Holder of such Note, without service charge, a new Note or Notes equal in principal amount to any unpurchased portion of the Note or Notes surrendered. 

Section 8.06 Covenant to Comply With Securities Laws upon Purchase of Notes 

In connection with any offer to purchase Notes under Section 8.01, the Company shall, if required: 

(a) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other of the tender offer rules under the Exchange Act that may then be
applicable; 
 (b) file a Schedule TO or any other required schedule under the Exchange Act; and 

(c) otherwise comply with all federal and state securities laws in connection with any offer by the Company to purchase the Notes. 

Section 8.07 Repayment to the Company 

Subject to the requirements of any applicable abandoned property laws, regardless of who acts as Paying Agent, the Paying Agent shall return to
the Company any cash that remains unclaimed, together with interest, if any, thereon, held by them for the payment of the Fundamental Change Purchase Price; provided that to the extent that the aggregate amount of cash deposited by the Company
pursuant to Section 8.04 exceeds the aggregate Fundamental Change Purchase Price of the Notes or portions thereof which the Company is obligated to 

  
 128 








 
purchase as of the Fundamental Change Purchase Date, then as soon as practicable following the Fundamental Change Purchase Date, the Paying Agent shall return any such excess to the Company.

The Trustee shall not be charged with knowledge of any Event of Default, except as provided in Section 11.03(i). 

Section 9.02 Acceleration of Maturity: Waiver of Past Defaults and Rescission 

(a) If an Event of Default (other than those specified in Sections 9.01(i) and 9.01(j) involving any Credit Party) occurs and is continuing,
then and in every such case the Requisite Holders may, or the Trustee, at the written request of the Requisite Holders, shall, declare 100% of the Principal Amount plus accrued and unpaid interest on all the outstanding Notes (including but not
limited to any outstanding accrued but not yet capitalized PIK Interest and all outstanding capitalized PIK Interest) and any outstanding Make-Whole Payment (and all other Obligations), to be due and payable immediately, by a notice in writing to
the Company (and to the Trustee if given by such Holders), and upon any such declaration such Principal Amount plus accrued and unpaid interest (and all other Obligations) shall become immediately due and payable. 

Notwithstanding the foregoing, in the case of an Event of Default specified in Section 9.01(i) or Section 9.01(j) with respect to
any Credit Party, 100% of the Principal Amount plus accrued and unpaid interest on all outstanding Notes (including but not limited to any outstanding accrued but not yet capitalized PIK Interest and all outstanding capitalized PIK Interest) and any
outstanding Make-Whole Payment (and all other Obligations), will automatically become due and payable without any declaration or other act on the part of the Trustee or any Holder. 

(b) The Requisite Holders, by written notice to the Company and the Trustee, may (x) waive any past Default and its consequences and
(y) at any time after a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article 9 provided, rescind any such acceleration with
respect to the Notes and its consequences, except, in each case, with respect to 

  
 131 








 
a Default described in Section 9.01(a), Section 9.01(b) or Section 9.01(c) (which, in each case shall require the approval of each Holder directly affected by such Default), or in
respect of a covenant or provision hereof which under Article 14 cannot be modified or amended without the consent of the Holder of each outstanding Note affected, if: 

(i) such rescission will not conflict with any judgment or decree of a court of competent jurisdiction; and 

(ii) all existing Events of Default (other than the non-payment of any Principal Amount or interest or any other Obligation
that became due solely by such declaration of acceleration) have been cured or waived. 
 Upon any such waiver, the Default which has been
waived shall cease to exist and any Event of Default arising therefrom shall be deemed to have been cured, for every other purpose of the Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent.

 No such rescission shall affect any subsequent default or impair any right consequent thereon. 

Section 9.03 Additional Interest 

If an Event of Default occurs and is continuing, if so elected by the Requisite Holders, in addition to ordinary interest payable pursuant to
Section 4.01, the Company shall pay Additional Interest on the Notes, which shall accrue at the rate of 2.0% per annum of the Principal Amount of Notes outstanding for each day during the period from and including the date on which such
Event of Default first occurs to and including the date on which such Event of Default has been cured or waived or ceases to exist. Additional Interest shall also mean all amounts, if any, payable pursuant to the Registration Rights Agreement. Any
Additional Interest payable pursuant to this Section 9.03 will be payable in arrears on each Interest Payment Date following accrual in the same manner as ordinary interest is payable pursuant to Section 4.01. Notwithstanding the
foregoing, the accrual and/or payment of such Additional Interest shall not preclude, forebear, waive or delay the rights of the Holders hereunder to accelerate the Notes as provided in Section 9.02 or to elect or exercise any other remedies
available to them hereunder or under applicable law. 
 Section 9.04 Collection of Indebtedness and Suits for Enforcement by
Trustee 
 The Company covenants that if a Default is made in the payment of the Principal Amount plus accrued and unpaid interest on the
Maturity Date therefor or in the payment of the Fundamental Change Purchase Price and any Make-Whole Payment which is then due and payable in respect of any Note, the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Notes, the whole amount then due and payable on such Notes, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel. 

  
 132 








 If an Event of Default occurs and is continuing, the Trustee, with the consent of the Requisite
Holders, may, but shall not be obligated to, pursue any available remedy, including but not limited to an Enforcement Action as contemplated under Article 5 hereof, to collect the payment of the Principal Amount plus accrued but unpaid interest on
the Notes (including but not limited to any outstanding accrued but not yet capitalized PIK Interest and all outstanding capitalized PIK Interest) and any outstanding Make-Whole Payment, or to enforce the performance of any provision of the Notes or
this Indenture. The Trustee may maintain a proceeding even if the Trustee does not possess any of the Notes or does not produce any of the Notes in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of, or acquiescence in, the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative. 

Section 9.05 Trustee May File Proofs of Claim 

In case of any judicial proceeding relative to the Company (or any other obligor upon the Notes), its property or its creditors, the Trustee
shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under this Indenture and applicable law in order to have claims of the Holders and the Trustee allowed in any such proceeding.
In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the
Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee under Section 11.07. 

No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

Section 9.06 Application of Money Collected 

Subject to the Intercreditor Agreement, any money collected by the Trustee pursuant to this Article or the Collateral Trustee pursuant to the
Security Documents shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money to Holders, upon presentation of the Notes and the notation thereon of the payment if only partially
paid and upon surrender thereof if fully paid: 
 FIRST: To the payment of all amounts due the Trustee and the Collateral Trustee under
Section 11.07; 
 SECOND: To the payment of the amounts then due and unpaid on the Notes for the Principal Amount, Fundamental Change
Purchase Price, interest (including but not limited to any outstanding accrued but not yet capitalized PIK Interest and all outstanding capitalized PIK 

  
 133 








 
Interest) and any outstanding Make-Whole Payment and other Obligations, as the case may be, in respect of which or for the benefit of which such money has been collected, ratably, without
preference or priority of any kind, according to the amounts due and payable on such Notes; and 
 THIRD: To the payment of the remainder,
if any, to the Company or any other Person lawfully entitled thereto. 
 Section 9.07 Limitation on Suits 

No Holder of any Note shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, the Notes, the
Subsidiary Guarantees or for the appointment of a receiver or trustee, or for any other remedy hereunder unless (a) an Event of Default specified in Section 9.01(a), Section 9.01(b) or Section 9.01(c) occurs which directly
affects such Holder or (b) the Requisite Holders shall have made written request to the Trustee or the Collateral Trustee to institute a proceeding in its own name as Trustee or Collateral Trustee hereunder and offered to the Trustee or
Collateral Trustee, as applicable, security or indemnity satisfactory to it against any loss, liability or expense and the Trustee or the Collateral Trustee, as applicable, for seven (7) days after its receipt of such request and offer of
security or indemnity has failed to institute any such proceeding. In the case of (a) in the immediately preceding sentence, Holders shall be entitled to, but shall not be obligated to pursue, any right or remedy that would otherwise be
available to the Trustee or the Collateral Trustee under this Indenture. In the case of (b) in the immediately preceding sentence, the Requisite Holders shall be entitled to, but shall not be obligated to pursue, any right or remedy that would
otherwise be available to the Trustee or the Collateral Trustee under this Indenture. Notwithstanding the forgoing, no one or more Holders shall have any right in any manner whatever by virtue of, or by availing itself of, any provision of this
Indenture to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the
equal and ratable benefit of all the Holders (it being understood that neither the Trustee nor the Collateral Trustee has an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders). 

Section 9.08 Unconditional Right of Holders to Receive Payment 

Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of the Principal Amount (including the
Fundamental Change Purchase Price or interest in respect of the Notes held by such Holder, on or after the respective due dates expressed in the Notes, or any Fundamental Change Purchase Date, any other Obligation or otherwise, as applicable), any
accrued and unpaid interest (including Additional Interest, if any) and to convert the Notes in accordance with Article 7, or to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, shall not

 Section 9.09 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 proceeding, the Company, the Trustee and the Holders shall be restored
severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 

Section 9.10 Rights and Remedies Cumulative 

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in the last paragraph of
Section 3.09, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder shall not prevent the concurrent assertion or employment of any
other appropriate right or remedy. 
 Section 9.11 Delay or Omission Not Waiver 

No delay or omission of the Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 
 Section 9.12 Control by Holders 

The Requisite Holders may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or Collateral
Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with applicable law or this Indenture or that the Trustee determines is unduly prejudicial to the rights of
any other Holder or that would involve the Trustee in personal liability. Prior to taking any action under this Indenture, the Trustee will be entitled to indemnification from the Holders satisfactory to it in its sole discretion against all losses
and expenses caused by taking or not taking such action. 
 Section 9.13 Undertaking for Costs 

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted
by it as Trustee, in either case in respect of the Notes, a court may require any party litigant in such suit to file an undertaking to pay the costs of the suit, and the court may assess reasonable costs, including reasonable attorney’s fees
and expenses, against any party litigant in the suit having due regard to the merits and good faith of the claims or defenses made by the party litigant; but the provisions of this Section 9.13 shall not apply to any suit instituted by the
Company, 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 outstanding Notes, or to any suit instituted by any Holder for the
enforcement of the payment of the Principal Amount on any Note on or after the Maturity Date of such Note or the Fundamental Change Purchase Date.

TRUSTEE 
 Section 11.01 Duties and Responsibilities of Trustee 

(a) The Trustee, prior to the occurrence of an Event of Default and after the curing of all Events of Default which may have occurred,
undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in
it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his own affairs. 

(b) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own 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 which 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 which 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); 

  
 136 








 (ii) the Trustee shall not be liable for any error of judgment made in good faith
by a Trust Officer or Officers of the Trustee, unless 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 written direction of the Requisite Holders at the time outstanding determined as provided in Section 1.04
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; 

(iv) whether or not therein 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; 
 (v) the Trustee shall not be
liable in respect 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-Registrar with respect to
the Notes; and 
 (c) 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. 

None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal
financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it. 
 Section 11.02 Notice of Defaults 

The Trustee shall give the Holders notice of any Default of which the Trustee has knowledge (as provided in Section 11.03(i)) within
ninety (90) days after the occurrence thereof so long as such Default is continuing; provided, that (except in the case of any Default in the payment of Principal Amount of, or interest on, any of the Notes or Fundamental Change Purchase
Price or a default in the delivery of the consideration due upon conversion), the Trustee shall be protected in withholding such notice if and so long as a committee of officers of the Trustee in good faith determines that the withholding of such
notice is in the interest of the Holders of Notes. 
 Section 11.03 Reliance on Documents, Opinions, Etc. 

Except as otherwise provided in Section 11.01: 

(a) the Trustee may rely and shall be protected in acting upon any resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, bond, debenture, note, coupon or other paper or document (whether in its original or facsimile form) believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties; 

  
 137 








 (b) to the extent requested by the Trustee, any request, direction, order or demand of the

the Trustee by a copy thereof certified by the Secretary, any Assistant Secretary or the General Counsel of the Company; 
 (c) the Trustee
may consult with counsel of its own selection and any advice or Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or omitted by it hereunder in good faith and in accordance with such advice or
Opinion of Counsel; 
 (d) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture
at the request, order or direction of any of the Holders pursuant to the provisions of this Indenture (including upon the occurrence and during the continuance of an Event of Default), unless such Holders shall have offered to the Trustee security
or indemnity satisfactory to it against any loss, expenses and liabilities which may be incurred therein or thereby; 
 (e) the Trustee
shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the
Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books,
records and premises of the Company, personally or by agent or attorney (at the reasonable expense of the Company and shall incur no liability of any kind by reason of such inquiry or investigation); 

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

(g) the Trustee shall not be liable for any action taken, suffered, or omitted to be taken by it and believed by it to be authorized or within
the discretion or rights or powers conferred upon it by this Indenture, in each case without negligence, willful misconduct or bad faith on the part of the Trustee, unless it is proved in a court of competent jurisdiction that the Trustee was
negligent in ascertaining the pertinent facts; 
 (h) in no event shall the Trustee be responsible or liable for special, indirect, or
consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action; 

  
 138 








 (i) the Trustee shall not be deemed to have notice of any Default or Event of Default unless a
Trust Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee from any Holder or any Credit Party, and such
notice references the Notes and the Indenture (and in the absence of such actual knowledge or such notice, the Trustee may conclusively assume that no such Default or Event of Default exists); and 

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

Section 11.04 No Responsibility for Recitals, Etc. 

The recitals contained herein and in the Notes (except in the 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 Indenture, the Notes, any of the Security Documents, the Intercreditor Agreement,
the Subordination Agreement, any Officers’ Certificate, or any Opinion of Counsel. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any Notes authenticated and delivered by the
Trustee in conformity with the provisions of this Indenture. 
 Section 11.05 Trustee, Paying Agents, Conversion Agents or Registrar
May Own Notes 
 The Trustee, any Paying Agent, any Conversion Agent or Registrar, in its individual or any other capacity, may become
the owner or pledgee of Notes with the same rights it would have if it were not Trustee, Paying Agent, Conversion Agent or Registrar. 

Section 11.06 Monies to be Held in Trust 

Subject to the provisions of Section 13.04, all monies and properties received by the Trustee shall, until used or applied as herein
provided, be held in trust for the purposes for which they were received. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest
on any money received by it hereunder except as may be agreed in writing from time to time by the Company and the Trustee. 

Section 11.07 Compensation and Expenses of Trustee 

The Company covenants and agrees to pay to the Trustee 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 from time to time in writing between the Company and the
Trustee, and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its gross negligence, willful misconduct or bad faith. The
Company also covenants to indemnify the 

  
 139 








 
Trustee (or any officer, director or employee of the Trustee), in any capacity under this Indenture and its agents and any authenticating agent for, and to hold them harmless against, any and all
loss, liability, claim or expense incurred without gross negligence, willful misconduct or bad faith on the part of the Trustee or such officers, directors, employees and agent or authenticating agent, as the case may be, and arising out of or in
connection with the acceptance or administration of this trust or in any other capacity hereunder, including the costs and expenses of 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. The obligations of the Company under this Section 11.07 to compensate or indemnify the Trustee and to pay or reimburse the
Trustee for expenses, disbursements and advances shall be secured by a lien prior to that of the Notes upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of particular
Notes. The obligation of the Company under this Section shall survive the satisfaction and discharge of this Indenture. 
 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(i) or Section 9.01(j) with respect to the Company 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) to the extent applicable. 
 Section 11.08 Officers’ Certificate as
Evidence 
 Except as otherwise provided in Section 11.01, 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, in the absence of
negligence or willful misconduct on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate delivered to the Trustee. 

Section 11.09 Conflicting Interests of Trustee 

If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, 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. 

Section 11.10 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 to act as such and
has a combined capital and surplus of at least $50,000,000 (or if such Person is a member of a bank holding company system, its bank holding company shall have 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. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 11.10, it shall resign immediately in the manner and with the
effect hereinafter specified in this Article. 

  
 140 








 This Indenture shall always have a Trustee who satisfies the requirements of Trust Indenture Act
§ 310(a)(1), (2) and (5). The Trustee is subject to Trust Indenture Act § 310(b). 
 Section 11.11 Resignation or
Removal of Trustee 
 (a) The Trustee may at any time resign by giving written notice of such resignation to the Company and to the
Holders of Notes. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Company’s 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 sixty (60) days after the mailing of such notice of resignation to the Holders, the
resigning Trustee may, upon ten (10) Business Days’ notice to the Company and the Holders, appoint a successor identified in such notice or may petition, at the expense of the Company, any court of competent jurisdiction for the
appointment of a successor trustee, or, if any Holder who has been a bona fide Holder of a Note or Notes for at least six (6) months may, subject to the provisions of Section 9.13, on behalf of himself 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. 

(b) In case at any time any of the following shall occur: 

(i) the Trustee shall fail to comply with Section 11.09 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; or 
 (ii) the Trustee shall cease to be
eligible in accordance with the provisions of Section 11.10 and shall fail to resign after written request therefor by the Company or by any such Holder; or 

(iii) 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; 

then, in any such case, the Company may remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the
Company’s Board of Directors, 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 9.13, any Holder who has been a bona fide Holder of a
Note or Notes for at least six (6) months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee; provided,
however, that if no successor Trustee shall have been appointed and have accepted appointment sixty (60) days after either the Company or the Holders has removed the Trustee, the Trustee so removed may petition at its own expense any court
of competent jurisdiction for an 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. 

  
 141 








 (c) The Requisite Holders at the time outstanding may at any time remove the Trustee with or
without cause and nominate a successor trustee which shall be deemed appointed as successor trustee. 
 (d) Any resignation or removal of
the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 11.11 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 11.12. 

Section 11.12 Acceptance by Successor Trustee 

Any successor trustee appointed as provided in Section 11.11 shall execute, acknowledge and deliver to the Company and to its 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 amount then due it pursuant to the provisions of Section 11.07, 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 lien upon all property and funds 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 pursuant to the provisions of Section 11.07. 

No successor trustee shall accept appointment as provided in this Section 11.12 unless, at the time of such acceptance, such successor
trustee shall be qualified under the provisions of Section 11.09 and be eligible under the provisions of Section 11.10. 
 Upon
acceptance of appointment by a successor trustee as provided in this Section 11.12, the Company (or the former trustee, at the written direction of the Company) shall mail or cause to be mailed notice of the succession of such trustee hereunder
to the Holders of Notes at their addresses as they shall appear on the Register. If the Company fails to mail such notice within ten (10) days after acceptance of appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Company. 
 Section 11.13 Succession by Merger, Etc. 

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee (including any trust created by 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 

  
 142 








 
succeeding to all or substantially all of the corporate trust business of the Trustee, such corporation shall be qualified under the provisions of Section 11.09 and eligible under the
provisions of Section 11.10. 
 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 any authenticating agent appointed by such successor trustee may authenticate such Notes in the name of
the successor trustee; and in all such cases such certificates shall have the full force that is provided in the Notes or in this Indenture; provided, however, that the right to adopt the certificate of authentication of any predecessor
Trustee or authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation. 

Section 11.14 Preferential Collection of Claims 

If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Notes), the Trustee shall be subject to the
provisions of § 311(a) of the Trust Indenture Act, excluding any creditor relationship listed in § 311(b), regarding the collection of the claims against the Company (or any such other obligor). A Trustee who has resigned or been removed
shall be subject to § 311(a) to the extent indicated therein. 
 Section 11.15 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 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 (3) Business Days after the date any officer of the Company 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 an omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or
omitted. 
 Section 11.16 Collateral Trustee 

In acting as Collateral Trustee, the Collateral Trustee may rely upon, and shall be entitled to the benefits, rights, protections, immunities
and indemnities of and to enforce, each and all of the rights, powers, immunities, indemnities and benefits of the Trustee under this Indenture including, without limitation, those set forth in this Article 11 as well as in Sections 1.02 and 1.03.
The Collateral Trustee may resign or be removed, and the Collateral Trustee’s successor shall be appointed in the same manner as provided with respect to the Trustee under this Article 11 (for the avoidance of doubt, the provisions of Sections
11.11 and 11.12 of this Indenture shall be interpreted to apply to the Collateral Trustee as if it was referenced therein in lieu of the Trustee).

shall have become due and payable, shall be repaid to the Company by the Trustee on demand and all liability of the Trustee shall thereupon cease with respect to such monies or shares of Common Stock; and the Holder of any of the Notes shall
thereafter look only to the Company for any payment or delivery that such Holder may be entitled to collect unless an applicable abandoned property law designates another Person. 

Section 13.05 Reinstatement 

If the Trustee or the Paying Agent is unable to apply any money or shares of Common Stock in accordance with Section 13.02 by reason of
any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had
occurred pursuant to Section 13.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money or shares of Common Stock in accordance with Section 13.02; provided, however, that if the Company makes any
payment of interest on or principal of any Note or delivery of shares of Common Stock due upon conversion following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such
payment from the money, or delivery from the shares of Common Stock, as the case may be, held by the Trustee or Paying Agent.

 ARTICLE 15 

GUARANTEES OF NOTES 

Section 15.01 Subsidiary Guarantees 

Subject to this Article 15, 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 and/or the Obligations of the Company hereunder and thereunder, that: 
 (a) the principal of, and interest on, each of
the Notes will be promptly paid in full when due, whether at stated maturity, by required prepayment, declaration, demand, by acceleration, upon repurchase or otherwise, and interest on the overdue principal of and (to the extent permitted by law)
interest (including but not limited to any outstanding accrued but not yet capitalized PIK Interest, all outstanding capitalized PIK Interest and any Additional Interest, and any interest, fees, costs or charges that would accrue but for the
provisions of Title 11 of the United States Code after any bankruptcy or insolvency petition under Title 11 of the United States Code) and any outstanding Make-Whole Payment on the Notes, and all other payment obligations of the Company to the
Holders or the Trustee under this Indenture or the Notes will be promptly paid in full and performed, all in accordance with the terms hereof and thereof; and 

(b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, the same will 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 (a) and
(b) being herein collectively called the “Guaranteed Obligations”). 
 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. 

  
 149 








 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 or this Indenture 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. 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: 
 (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 or the Trustee as security for any of the Guaranteed Obligations shall fail to be perfected; or 

(v) the release of any other Guarantor. 

Each Guarantor further, to the 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. 
 If any Holder or the Trustee is required by any court or
otherwise to return to the Credit Parties, or any custodian, Trustee or other similar official acting in relation to any Credit Party, any amount paid by any Credit Party to the Trustee or such Holder, the Subsidiary Guarantees, to the extent
theretofore discharged, shall be reinstated in full force and effect. Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of
the obligations guaranteed hereby. 

  
 150 








 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 Article 9 hereof (and shall be deemed to have become automatically due and payable in the circumstances in said Article
9) 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 Article 9 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. 

Section 15.02 [Reserved] 

Section 15.03 Releases of Subsidiary Guarantees 

The Subsidiary Guarantee of a Guarantor shall be automatically and unconditionally released: (1) in connection with any Disposition
(including by way of merger or consolidation) of the Capital Stock of such Guarantor to a Person that is not (either before or after giving effect to such transaction) a Credit Party, to the extent such sale is permitted hereunder or to the extent
such Capital Stock constitutes Excluded Property; (2) upon the designation of such Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture; (3) upon satisfaction and discharge of this Indenture in accordance
with Article 13 or (4) upon payment of the Obligations in full in immediately available funds. 
 Upon delivery by the Company to the
Trustee of an Officers’ Certificate to the effect that any of the conditions described in the foregoing clauses (1), (2), (3) or (4) has occurred, 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 15. 

Further, the Subsidiary Guarantees with respect to a Note are not convertible and will automatically terminate when that Note is converted in
accordance with Article 7. 
 Section 15.04 Instrument for the Payment of Money. 

Each Guarantor hereby acknowledges that the guarantee in this Article 15 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 15.05
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 

  
 151 








 
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 15.06 “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 15 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 15 in place of the Trustee. 
 ARTICLE 16

that the only obligations secured by such Mortgage are the Obligations hereunder and is otherwise substantially similar to the Mortgage entered into on the date hereof. If so directed by the Requisite Holders, and accompanied by an Officer’
Certificate and Opinion of Counsel, the Collateral Trustee shall sign such amended and restated Mortgage.

In determining whether the Holders of the required Principal Amount of Notes have concurred in any direction, waiver or consent, Notes owned by
the Credit Parties or by any Affiliate of the Credit Parties shall be disregarded and deemed not to be outstanding, except that, for the purpose of determining whether the Trustee shall be protected in relying on any such direction, waiver or
consent, only Notes which a Trust Officer of the Trustee actually knows are so owned shall be so disregarded. Also, subject to the foregoing, only Notes outstanding at the time shall be considered in any such determination. For purposes of this
Section 16.04, the Permitted Holders shall not be deemed to be Affiliates of the Credit Parties.

Change Purchase Date or other payment date, as the case may be.

Recourse against Others 
 An incorporator, director, officer, employee, Affiliate or shareholder of any Credit Party, solely by reason
of this status, shall not have any liability for any Obligations, or for any claim based on, in respect of or by reason of such Obligations or their creation. By accepting a Note, each Holder shall waive and release all such liability. The waiver
and release shall be part of the consideration for the issue of the Notes. 
 Section 16.09 Successors 

All agreements of the Credit Parties in this Indenture and the Notes shall bind their respective successors. All agreements of the Trustee in
this Indenture shall bind its successors.

 EXHIBIT C 

GEVO, INC. 
 10.0%
Convertible Senior Secured Notes due 2017 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its
10.0% Convertible Senior Secured Notes due 2017 (the “Notes”), issued or to be issued under and pursuant to an Indenture dated as of June 6, 2014 (the “Indenture”) among the Company, the guarantors named on the
signature pages thereof (the “Guarantors”), and Wilmington Savings Fund Society, FSB, as Trustee (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, the Guarantors and the Holders of the Notes. The Indenture provides that Additional Notes may be issued thereunder, if certain
conditions are met. 
 (1) Interest. The Notes will bear interest at a rate of 10.0% per year. Pursuant to
Section 9.03 of the Indenture, in certain circumstances, the Holders of Notes shall be entitled to receive Additional Interest. Interest on the Notes will accrue from, and including, the Issue Date, or from the most recent date to which
interest has been paid or duly provided for. Interest will be payable quarterly in arrears on each Interest Payment Date, beginning with the first Interest Payment Date which occurs after the Issue Date, in cash; provided, that
if no Event of Default has occurred and is continuing under the Notes and the Last Reported Sale Price of the Common Stock on the 10th Trading Day immediately preceding the relevant Interest
Payment Date is more than $1.10 per share (as adjusted for stock splits, combinations, stock dividends and the like), then 50% of the interest will be payable on such Interest Payment Date in cash, and 50% of the interest will be payable on such
Interest Payment Date, either (i) by increasing the Principal Amount of the Notes or (ii) by issuing PIK Notes (“PIK Interest”), at the Company’s option. PIK Interest on the Notes will be payable by increasing the
Principal Amount of the Notes by an amount equal to the amount of PIK Interest for the applicable interest period (rounded up to the nearest whole dollar) (or, if necessary, pursuant to the requirements of The Depository Trust Company or its
nominee, as the case, to authenticate new Global Notes executed by the Company with such increased Principal Amount of the Notes). Following an increase in the Principal Amount of the Notes as a result of a PIK Payment, the Notes will bear interest
on such increased Principal Amount from and after the date of such PIK Payment. 
 Interest will be paid to the Person in whose name
a Note is registered at the Close of Business on the March 15, June 15, September 15 and December 15 (whether or not such date is a Business Day), as the case may be, immediately preceding the relevant Interest Payment
Date. Interest on the Notes will be computed on the basis of a 360-day year composed of twelve 30-day months. 
 (2) Ranking and
Security. 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 and shall be subject to the Intercreditor Agreement referred to in the Indenture. 

  
 164 








 (3) Guarantees. 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. 

(4) No Optional Redemption. The Notes are not redeemable at the option of the Company prior to their stated maturity date. No sinking
fund is provided for the Notes. 
 (5) Purchase at the Option of the Holder Upon a Fundamental Change. Subject to the terms and
conditions of the Indenture, the Company shall become obligated, at the option of the Holder, to repurchase the Notes if a Fundamental Change occurs at any time prior to the Maturity Date at (i) 100% of the Principal Amount together, plus
(ii) accrued and unpaid interest to, but excluding, the Fundamental Change Purchase Date (including but not limited to any outstanding accrued but not yet capitalized PIK Interest and all outstanding capitalized PIK Interest), plus
(iii) the Fundamental Change Make-Whole Payment, which aggregate amount will be paid in cash. 
 (6) Withdrawal of Fundamental
Change Purchase Notice. Holders have the right to withdraw, in whole or in part, any Fundamental Change Purchase Notice by delivering to the Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture. The
right to withdraw the Fundamental Change Purchase Notice will terminate at the Close of Business on the Business Day immediately preceding the relevant Fundamental Change Purchase Date. 

(7) Payment of Fundamental Change Purchase Price. If money sufficient to pay the Fundamental Change Purchase Price of all Notes or
portions thereof to be purchased on a Fundamental Change Purchase Date is deposited with the Paying Agent on the Fundamental Change Purchase Date, such Notes will cease to be outstanding and interest will cease to accrue on such Notes (or portions
thereof) immediately after the Close of Business on such Fundamental Change Purchase Date, and the Holder thereof shall have no other rights as such (other than the right to receive the Fundamental Change Purchase Price, upon surrender of such
Note). 
 (8) Conversion. Subject to and upon compliance with the provisions of the Indenture (including without limitation the
conditions of conversion of this Note set forth in Article 7 thereof), the Holder hereof has the right, at its option, to convert the Principal Amount hereof or any portion of such principal which is at least $1,000 into shares of Common Stock at
the Applicable Conversion Rate. The Conversion Rate is initially 0.8633 shares of Common Stock per $1 Principal Amount of Notes (equivalent to an initial Conversion Price of approximately $1.1584), subject to adjustment in certain events described
in the Indenture. Upon conversion, the Company will deliver shares of Common Stock and the Voluntary Conversion Make-Whole Payment, all as set forth in the Indenture (which may be paid in cash or shares of Common Stock). No fractional shares will be
issued upon any conversion, but a payment in cash will be made, as provided in the Indenture, in respect of any fraction of a share which would otherwise be issuable upon the surrender of any Notes for conversion. Notes in respect of which a Holder


  
 165 








 
is exercising its right to require repurchase on a Fundamental Change Purchase Date may be converted only if such Holder withdraws the related election to exercise such right in accordance with
the terms of the Indenture. Subject to and upon compliance with the provisions of the Indenture (including without limitation the conditions of conversion of this Note set forth in Article 7 thereof), the Company may elect to require the Holder to
convert some or all of the Notes if a Conversion Event occurs. Upon such conversion, the Company will deliver shares of Common Stock and the Conversion Event Make-Whole Payment, all as set forth in the Indenture (which may be paid in cash or shares
of Common Stock). 
 In the event of a deposit or withdrawal of an interest in this Note, including an exchange, transfer, repurchase or
conversion of this Note in part only, the Trustee, as custodian of the Depository, shall make an adjustment on its records to reflect such deposit or withdrawal in accordance with the rules and procedures of the Depository. 

(9) Acceleration of Maturity. Subject to certain exceptions in the Indenture, if an Event of Default shall occur and be continuing, the
Principal Amount plus interest through such date on all the Notes may be declared due and payable in the manner and with the effect provided in the Indenture. 

(10) Supplemental Indentures with Consent of Holders; Waiver of Past Defaults. The Indenture permits, with certain exceptions as
therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Notes under the Indenture at any time by the Company, the Guarantors and the Trustee with the consent of
the Requisite Holders. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate Principal Amount of the outstanding Notes, on behalf of the Holders of all the Notes, to waive compliance by the Company with
certain provisions of the Indenture and certain past Defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of any provision of or applicable to this Note shall be conclusive and binding upon such Holder and
upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. 

(11) Registration of Transfer and Exchange. As provided in the Indenture and subject to certain limitations therein set forth, the
transfer of this Note is registrable in the Register, upon surrender of this Note for registration of transfer at the office or agency of the Company in the United States, duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes, of authorized denominations and for the same aggregate Principal Amount, will be
issued to the designated transferee or transferees. 
 No service charge shall be made for any such registration of transfer or exchange,
but the Company and the Registrar may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 

  
 166 








 Prior to due presentment of this Note for registration of transfer, the Company, the Guarantors,
the Trustee and the Registrar and any agent of the Company, the Guarantors or the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Company,
the Trustee nor any such agent shall be affected by notice to the contrary. 
 (12) Denominations. The Notes are issuable only in
registered form in minimum denominations of $1,000, and any PIK Notes in minimum denominations of $1.00, as provided in the Indenture and subject to certain limitations therein set forth. Notes are exchangeable for a like aggregate Principal Amount
of Notes of a different authorized denomination, as requested by the Holder surrendering the same. 
 (13) CUSIP Numbers. Pursuant to
a recommendation promulgated by the Committee on Uniform Note Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to
Holders of Notes. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed herein. 

This Note shall be governed by and construed in accordance with the laws of the State of New York. 

All terms used in this Note that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

creation, validity, perfection, enforceability and priority of the security interest of the Collateral Trustee in such Foreign Equity Interests (other than any Excluded Property) (all such actions described in clauses (i) through
(iii) above being referred to herein collectively as “Foreign Equity Interest Perfection Requirements”). Any provision of this Agreement (including the immediately preceding sentence) or any other Indenture Document to the

such Trademark with the appropriate notice of registration and all other notices and legends required by any applicable Legal Requirement, and (iv) not (and use commercially reasonable efforts to not permit any licensee or sublicensee thereof
to) do any act or knowingly omit to do any act whereby such Trademark may become invalidated or impaired in any way that could reasonably be expected to result in a Material Adverse Change. 

(b) Such Grantor (either itself or through licensees) will not do any act, or omit to do any act, whereby any material Patent owned by a
Grantor (other than those constituting Excluded Property) may become prematurely invalidated, forfeited, abandoned or dedicated to the public other than in as permitted under the Indenture. 

(c) Unless such Grantor shall have determined, in its reasonable business judgment, that doing so is not necessary for the continued efficient
and profitable operation of the business of the Grantors, such Grantor (either itself or through licensees) will, for each work covered by a material Copyright owned by a Grantor (other than those constituting Excluded Property), use copyright
notices as required under applicable copyright laws. Such Grantor will not (either itself or through licensees) do any act whereby any material portion of such Copyrights may fall into the public domain unless such Copyright(s) are no longer
material to 







 
the conduct of the business of the Grantors as such business is operated and allowing such Copyright(s) to fall into the public domain does not materially detract from any Grantor’s value or
the Collateral of any Grantor. 
 (d) Reserved.

registration relating to any Intellectual Property owned by a Grantor (other than that constituting Excluded Property and other than the Intellectual Property set forth on Schedule 3.7 hereof (which Schedule shall not be supplemented or
otherwise modified after the Closing Date without the consent of the Requisite Holders)) may become forfeited, abandoned or dedicated to the public unless permitted under Section 4.32(ix) of the Indenture, or of any adverse determination or
development (including, without limitation, the institution of, or any such determination or development in, any proceeding in the United States Patent and Trademark Office, the United States Copyright Office) regarding such Grantor’s ownership
of, or the validity of, such Intellectual Property or such Grantor’s right to register the same or to own and maintain the same which would reasonably be expected to result in a Material Adverse Change (excluding, in any event, office actions
issued in the ordinary course by the United States Patent and Trademark Office or any corresponding office in any country). Collateral Trustee shall promptly provide any Holder with a copy of any such notice upon such Holder’s request. 

(f) Whenever such Grantor, either by itself or through any agent, employee, or designee, shall file an application for the registration of any

of the fiscal quarter in which such filing occurs, and shall promptly (but in no event later than 45 days after the end of the fiscal quarter in which such filing occurs) execute and deliver, and have recorded, any and all agreements, instruments,
documents, and papers as is necessary to evidence the Collateral Trustee’s and the other Secured Parties’ security interest in any such Patent or Trademark and the goodwill and general intangibles of such Grantor relating thereto or
represented thereby (in each case, to the extent not constituting Excluded Property) or (ii) the United States Copyright Office or any successor to such office or agency within the United States, such Grantor shall report such filing to the
Collateral Trustee and shall execute and deliver, and have recorded, any and all agreements, instruments, documents, and papers as is necessary to evidence the Collateral Trustee’s and the other Secured Parties’ security interest in any
such Copyright, goodwill and general intangibles of such Grantor relating thereto or represented thereby (in each case, to the extent not constituting Excluded Property) within 30 days after the such application is filed. Collateral Trustee shall
provide the Holders with copies of any such agreements, instruments, documents and papers promptly upon receipt thereof. 
 (g) Unless such
Grantor shall have determined, in its reasonable business judgment, that doing so is not necessary for the continued efficient and profitable operation of the business of the Grantors, such Grantor will take all reasonable and necessary steps,
including, without limitation, in any proceeding before the United States Patent and Trademark Office, the United States Copyright Office and any similar office or agency (if applicable), to maintain and pursue each application (and to obtain the
relevant registration) and to maintain each registration 







 
of the material Intellectual Property owned by a Grantor (other than that constituting Excluded Property), including, without limitation, filing of applications for renewal, affidavits of use,
and payment of maintenance fees. 
 (h) In the event that any material Intellectual Property owned by a Grantor (other than that
constituting Excluded Property) is infringed, misappropriated or diluted by a third party, such Grantor shall, (i) to the extent that such Grantor deems commercially reasonable to do so, take action to protect such Intellectual Property and
promptly notify Collateral Trustee in regards to any material developments with respect to any litigation, settlement or settlement discussions related thereto and (ii) if such Intellectual Property is of material economic value, promptly
notify the Collateral Trustee after it learns thereof and to the extent that Grantor deems commercially reasonable to do so, sue for infringement, misappropriation or dilution, to seek injunctive relief where appropriate and to recover any and all
damages for such infringement, misappropriation or dilution. Collateral Trustee shall promptly provide any Holder with a copy of any such notice upon such Holder’s request. 

(i) Upon the occurrence and during the continuance of an Event of Default, upon the written request of the Requisite Holders or Collateral
Trustee (at the direction of the Requisite Holders), each Grantor will use its commercially reasonable efforts to obtain all consents and approvals necessary for the assignment to the Collateral Trustee or its designee of any license held by such
Grantor and to enable the Collateral Trustee or its designee to enforce the security interests granted hereunder. 
 (j) In the case of any
registered Foreign Intellectual Property (other than any Excluded Property) directly owned by any Grantor, each Grantor shall, if requested by Requisite Holders or Collateral Trustee (at the direction of the Requisite Holders), within the time frame
set forth in the last sentence of this clause (j), (i) execute, deliver to the Collateral Trustee, and record security agreements (or supplements thereto), covering all such registered Foreign Intellectual Property (other than any Excluded
Property) acquired, created, developed or otherwise obtained during the applicable Measurement Period, in appropriate form for recordation with the applicable foreign, international or multi-national registers (if applicable), to insure the
creation, validity, perfection, enforceability and priority of the security interests of the Collateral Trustee therein (to the extent not already subject to Collateral Trustee’s valid, perfected and enforceable security interests), and
(ii) take such additional actions or make such additional filings or recordings as Requisite Holders or Collateral Trustee (at the direction of the Requisite Holders) may reasonably request which are necessary under the laws of the applicable
Foreign Jurisdiction to insure the creation, validity, perfection, enforceability and priority of the security interest of the Collateral Trustee in such registered Foreign Intellectual Property (other than any Excluded Property) (all such actions
referred to in clauses (i) and (ii) are collectively referred to as “Foreign IP Perfection Requirements”). Any provision of this Agreement (including the immediately preceding sentence) or any other Indenture Document
to the contrary notwithstanding, no Grantor shall be obligated to comply with any Foreign IP Perfection Requirement with respect to any Foreign Intellectual Property (y) if the Company and the Requisite Holders agree that the cost of obtaining
a security interest therein or perfection thereof are excessive in relation to the value to the Secured Parties of the security to be afforded thereby and/or (z) in any Foreign Jurisdiction where effective Foreign IP Perfection Requirements
have not been satisfied if the consolidated revenues of the Credit Parties (without taking into account 







 
any revenues of any Subsidiary that is not a Credit Party) derived from the operations of the Credit Parties (without taking into account any revenues of any Subsidiary that is not a Credit
Party) in such Foreign Jurisdiction are less than ten percent (10%) of the consolidated revenues of the Credit Parties (without taking into account any revenues of any Subsidiary that is not a Credit Party) in all jurisdictions for the
Measurement Period ending on the most recent Due Date (“Individual Jurisdiction Cap”); provided that, if the consolidated revenues of the Credit Parties (without taking into account any revenues of any Subsidiary that is not a
Credit Party) for such Measurement Period derived from the operations of the Credit Parties (without taking into account any revenues of any Subsidiary that is not a Credit Party) in all Foreign Jurisdictions where Foreign IP Perfection Requirements
have not satisfied exceeds thirty-five percent (35%) of the consolidated revenues of all operations of the Credit Parties (without taking into account any revenues of any Subsidiary that is not a Credit Party) for such Measurement Period (the
“Overall Cap”), then the Grantors shall take steps to comply with the Foreign IP Perfection Requirements in such Foreign Jurisdictions chosen by the Grantors as shall be necessary to cause the Foreign IP Perfection Requirements to
have been satisfied so that the consolidated revenues of the Credit Parties (without taking into account any revenues of any Subsidiary that is not a Credit Party) for such Measurement Period derived from the operations of the Credit Parties
(without taking into account any revenues of any Subsidiary that is not a Credit Party) in Foreign Jurisdictions where Foreign IP Perfection Requirements have not been satisfied do not exceed the Overall Cap. Each Grantor shall satisfy, and
shall cause each other relevant applicable Grantor to satisfy, all such Foreign IP Perfection Requirements required above (x) with respect to the Foreign Intellectual Property that were registered in any jurisdiction in excess of the Individual
Jurisdiction Cap within 90 days after the Due Date in regards to the financial statements that reflect that such Individual Jurisdiction Cap has been exceeded or, if the cap has been exceeded already but no Foreign Intellectual Property was
registered in such jurisdiction, within ninety (90) days after such Foreign Intellectual Property is acquired, created, developed or arises and is registered, and (y) in such other Foreign Jurisdiction(s) solely to the extent as may be
necessary to cause the Overall Cap not to be exceeded, within 90 days after the Due Date for the financial statements in respect of any applicable Measurement Period, as the case may be, provided, in any each case, that the Requisite Holders or
Collateral Trustee (at the direction of the Requisite Holders) may grant an extension therefor if the applicable Grantor in respect thereof is using commercially reasonable efforts to comply with such requirements (all Foreign Intellectual Property
excluded from the Foreign IP Perfection Requirements as of any date of determination, the “Excluded Foreign Intellectual Property”). Each Grantor shall inform the Collateral Trustee of its acquisition, creation or development
of any new registered Foreign Intellectual Property during any fiscal quarter for which any action is required by this Section 4.7(j) within 45 days after the end of such fiscal quarter. Collateral Trustee shall provide the Holders with copies
of any such security agreements (and supplements thereto), filings and/or recordings executed, filed and/or recorded under this clause (j) (as applicable) promptly upon receipt thereof. 

4.8 Other Foreign Assets. Within ten (10) Business Days after the Credit Parties own in excess of $1,000,000 of Other Foreign
Assets which have been located in one jurisdiction for more than thirty (30) days, the Credit Parties shall notify the Collateral Trustee of such (and Collateral Trustee shall notify the Holders of such promptly upon being so notified) and,
within ninety (90) days after Requisite Holders or Collateral Trustee so requests (at the direction of the Requisite Holders), the applicable Credit Parties shall (i) execute, deliver to the








 
Collateral Trustee, and record security agreements (or supplements thereto), covering all such Other Foreign Assets (other than any Excluded Property), in appropriate form for recordation with
the applicable filing or recording offices, to insure the validity, perfection and priority of the security interests of the Collateral Trustee therein (to the extent not already subject to Collateral Trustee’s valid, perfected and enforceable
security interests), and (ii) take such additional actions or make such additional filings or recordings as Requisite Holders or Collateral Trustee (at the direction of the Requisite Holders) may reasonably request which are necessary
under the laws of the applicable Foreign Jurisdiction to insure the validity, perfection and priority of the security interest of the Collateral Trustee in such Other Foreign Assets (other than any Excluded Property) (the requirements set forth in
clauses (i) and (ii) of this Section 4.8, “Other Foreign Asset Perfection Requirements”). Collateral Trustee shall provide the Holders with copies of any such security agreements (and supplements thereto), filings
and/or recordings executed, filed and/or recorded under this Section 4.8 (as applicable) promptly upon receipt thereof. 
 4.9
Commercial Tort Claims. Such Grantor shall promptly notify the Collateral Trustee of any Commercial Tort Claim that is Collateral with potential value in excess of $250,000 acquired by it or otherwise arising (and Collateral Trustee shall
notify the Holders of such promptly upon being so notified) and, unless the Requisite Holders or Collateral Trustee otherwise consents (at the direction of the Requisite Holders), such Grantor shall, within 30 days of obtaining such interest,
supplement Schedule 6 with a description of such Commercial Tort Claim and sign and deliver documentation (and amend all applicable financing statements) necessary to grant to the Collateral Trustee a perfected first priority security
interest (subject to Permitted Liens) in such Commercial Tort Claim (subject to the Liens permitted under the Indenture) (“Commercial Tort Claim Perfection Requirements”) provided that the value of all Commercial Tort Claims for
which the Commercial Tort Claim Perfection Requirements have not been satisfied, shall not exceed $500,000 at any time. 
 4.10
Letter-of-Credit Rights. If such Grantor is or becomes the beneficiary of a letter of credit that is Collateral with a value in excess of $125,000, it shall promptly after becoming a beneficiary notify the Collateral Trustee thereof (and
Collateral Trustee shall notify the Holders of such promptly upon being so notified) and use commercially reasonable efforts to cause the issuer and/or confirmation bank to consent to the assignment of any Letter-of-Credit Rights in connection with
such letter of credit to the Collateral Trustee (or the Administrative Agent on behalf of the Secured Parties and/or the Secured Lender Parties and/or certain other secured parties) within thirty (30) days after becoming a beneficiary on such
letter of credit (“Letter of Credit Paper Perfection Requirements”) provided that the value of all such letters of credit for which the Letter of Credit Perfection Requirements have not been satisfied, shall not exceed $250,000 at
any time. 
 4.11 Collateral Access Agreements. Promptly following request by the Requisite Holders or Collateral Trustee (at the
direction of the Requisite Holders), each Grantor shall use commercially reasonable efforts to obtain a Collateral Access Agreement from the lessor of each leased property, mortgagee of owned property or bailee or consignee with respect to any
warehouse, processor or converter facility or other location where Collateral with value of at least $250,000 is stored or located or which is the location of the Company’s principal place of business, which agreement or letter shall provide
access rights, contain a waiver or subordination of all Liens or claims that the landlord, mortgagee, bailee or consignee may assert against the Collateral at that location, and shall otherwise be reasonably satisfactory in form and substance to the
Requisite Holders . 







 4.12 Motor Vehicles. Grantors shall promptly notify the Collateral Trustee of any goods
constituting Collateral covered by a certificate of title and owned by Grantors with an aggregate value in excess $250,000 (and Collateral Trustee shall notify the Holders of such promptly upon being so notified) and promptly (and in any event
within 30 days) after request by Requisite Holders or Collateral Trustee (at the direction of the Requisite Holders), with respect to such goods covered by a certificate of title owned by any Grantor(s), such Grantor(s) shall deliver to Collateral
Trustee or Collateral Trustee’s designee (or the Administrative Agent on behalf of the Secured Parties and/or the Secured Lender Parties and/or certain other secured parties), the certificates of title for all such goods and, if requested by
Requisite Holders or Collateral Trustee (at the direction of the Requisite Holders), (x) take all actions necessary to cause such certificates to be filed (with the Collateral Trustee’s Lien (or the lien of the Administrative Agent on
behalf of the Secured Parties and/or the Secured Lender Parties and/or certain other secured parties) noted thereon) in the appropriate state motor vehicle filing office and/or (y) cause Collateral Trustee’s Liens (or the Liens of the
Administrative Agent on behalf of the Secured Parties and/or the Secured Lender Parties and/or certain other secured parties) to be notated on such certificates of title. 

SECTION 5. COLLECTION AND APPLICATION OF COLLATERAL PROCEEDS; DEPOSIT ACCOUNTS 

5.1 Collection of Receivables. On or prior to the Closing Date, each Grantor shall execute and deliver to the Collateral Trustee,
Deposit Account Control Agreements for each Deposit Account and Securities Account Control Agreement for each Securities Account (other than (i) each Deposit Account or Securities Account, the funds in which are used solely for trust, fiduciary
or escrow payments (in each case related to employee compensation), tax payments, payroll, payroll taxes, worker’s compensation, pension benefits or other employee and wage benefit payments and similar expenses or taxes related thereto,
(ii) each Deposit Account and Securities Account that has an ending daily balance of zero, (iii) other Deposit Accounts and Securities Accounts so long as the average daily balance on deposit in any such Deposit Account and/or average
daily amount of funds and other assets maintained in such Securities Account does not exceed $25,000 at any time, in each case, so long as the average daily balance in all of such Deposit Accounts and the average daily amount of funds and other
assets in all Securities Accounts under this clause (iii) does not exceed $100,000 in the aggregate at any time, (iv) any Deposit Account and Securities Account which solely contain deposits subject to Liens permitted by clauses (f), (j),
(o), (q), (r), (s), (u), (x), (y), (bb), (gg) and (hh) of Section 4.29 of the Indenture solely to the extent that the grant of a security interest or lien in such Property or Deposit Account is prohibited under the terms of the contract
governing such Permitted Lien, and (v) any Deposit Accounts or Security Accounts that only holds Excluded Property (the Deposit Account and Securities Accounts described in clauses (i) – (v), collectively, “Excluded
Deposit/Security Accounts”)) maintained by such Grantor (such Deposit Accounts and Security Accounts, excluding all Excluded Deposit/Security Accounts, each, a “Collateral Account”), which Deposit Accounts and Securities
Accounts as of the Closing Date are identified as such on Schedule 7 hereto. 







 5.2 Covenant Regarding New Deposit Accounts. Before opening, transferring or replacing
any Collateral Account or other Deposit Account or Securities Account, each Grantor shall so notify the Collateral Trustee (and Collateral Trustee shall notify the Holders of such promptly upon being so notified) and such Grantor shall cause each
bank or financial institution in which it seeks to open a Deposit Account or Securities Account (in each case, other than Excluded Deposit/Securities Accounts), to enter into a Deposit Account Control Agreement or Securities Account Control
Agreement (as applicable) with the Collateral Trustee (or the Administrative Agent on behalf of the Secured Parties and/or the Secured Lender Parties and/or certain other secured parties). 

SECTION 6. REMEDIAL PROVISIONS 
 6.1
Certain Matters Relating to Receivables. The Collateral Trustee hereby authorizes each Grantor to collect such Grantor’s Receivables, and the Requisite Holders or Collateral Trustee (at the direction of the Requisite Holders) may curtail
or terminate said authority at any time after the occurrence and during the continuance of an Event of Default. If required by the Requisite Holders or Collateral Trustee (at the direction of the Requisite Holders) at any time after the occurrence
and during the continuance of an Event of Default, any payments of Receivables, when collected by any Grantor, (i) shall be forthwith (and, in any event, within two (2) Business Days) deposited by such Grantor in the exact form received,
duly indorsed by such Grantor to the Collateral Trustee if required, in a Deposit Account constituting a Collateral Account under the Control of the Collateral Trustee (or the Administrative Agent on behalf of the Secured Parties and/or the Secured
Lender Parties and/or certain other secured parties), subject to withdrawal by the Collateral Trustee (at the direction of the Requisite Holders) for the account of the Secured Parties, to be applied to the Secured Obligations in accordance with
Section 6.5 hereof, and (ii) until so turned over, shall be held by such Grantor in trust for the Collateral Trustee and the other Secured Parties, segregated from other funds of such Grantor. The Grantors and the Collateral Trustee
recognize that setoffs, counterclaims, defenses and other claims may be asserted by obligors with respect to certain of the Receivables, that certain of the Receivables may be or become uncollectible in whole or in part and that the expense and
probability of success in litigating a disputed Receivable may exceed the amount that reasonably may be expected to be recovered with respect to a Receivable. In view of the foregoing, each Grantor agrees that the Requisite Holders or Collateral
Trustee (acting at the direction of the Requisite Holders) may at any time and from time to time, if an Event of Default has occurred and is continuing, compromise with the obligor on any Receivable, accept in full payment of any Receivable such
amount as the Requisite Holders in their reasonable judgment shall determine or abandon any Receivable, and any such action by the Collateral Trustee shall be deemed to be commercially reasonable so long as the Collateral Trustee (x) acts in
good faith based on information known to it at the time it takes any such action or (y) acts at the direction of the Requisite Holders and the Requisite Holders have given such direction in good faith based on information known to them at the
time that they gave such direction. 
 6.2 Communications with Obligors; Grantors Remain Liable. (a) The Requisite Holders or
Collateral Trustee in its own name or in the name of others may (at the direction of the Requisite Holders) at any time after the occurrence and during the continuance of an Event of Default communicate (by mail, telephone, facsimile, email or
otherwise) with obligors under the Receivables to verify with them to the Requisite Holders’ satisfaction the existence, amount and terms of any Receivables. 







 (b) Upon the request of the Requisite Holders or Collateral Trustee (at the direction of the
Requisite Holders) at any time after the occurrence and during the continuance of an Event of Default, each Grantor shall notify obligors on the Receivables that the Receivables have been assigned to the Collateral Trustee for the ratable benefit of
the Secured Parties and that payments in respect thereof shall be made directly to the Collateral Trustee. 
 (c) Anything herein to the
contrary notwithstanding, each Grantor shall remain liable under each of the Receivables to observe and perform all the conditions and obligations to be observed and performed by it thereunder, all in accordance with the terms of any agreement
giving rise thereto. Neither the Collateral Trustee nor any other Secured Party shall have any obligation or liability under any Receivable (or any agreement giving rise thereto) by reason of or arising out of this Agreement or the receipt by the
Collateral Trustee or any other Secured Party of any payment relating thereto, nor shall the Collateral Trustee or any other Secured Party be obligated in any manner to perform any of the obligations of any Grantor under or pursuant to any
Receivable (or any agreement giving rise thereto), to make any payment, to make any inquiry as to the nature or the sufficiency of any payment received by it or as to the sufficiency of any performance by any party thereunder, to present or file any
claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to it or to which it may be entitled at any time or times. 

6.3 Pledged Equity. (a) Unless an Event of Default shall have occurred and be continuing and the Collateral Trustee shall have
given notice (acting at the direction of the Requisite Holders) to the relevant Grantor of the Collateral Trustee’s intent to exercise its corresponding rights pursuant to Section 6.3(b) hereof, each Grantor shall be permitted to receive
all cash dividends paid in respect of the Pledged Equity and all payments made in respect of the Pledged Notes, in each case, to the extent permitted in the Indenture, and to exercise all voting and corporate or other organizational rights with
respect to the Investment Property that constitutes Collateral; provided, however, that no vote shall be cast or corporate or other organizational right exercised or other action taken which would be inconsistent with or result in any violation of
any provision of the Indenture, this Agreement or any other Security Document. 
 (b) If an Event of Default shall occur and be continuing
and the Collateral Trustee shall give notice (acting at the direction of the Requisite Holders) of its intent to exercise such rights to the relevant Grantor or Grantors, (i) the Collateral Trustee shall have the right to receive any and all
cash dividends, payments or other Proceeds paid in respect of the Investment Property that constitutes Collateral and shall make application thereof to the Secured Obligations in the order set forth in the Indenture, and (ii) any or all of the
Investment Property that constitutes Collateral shall be registered in the name of the Collateral Trustee or its nominee (or the Administrative Agent on behalf of the Secured Parties and/or the Secured Lender Parties and/or certain other secured
parties), and the Collateral Trustee or its nominee (or the Administrative Agent on behalf of the Secured Parties and/or the Secured Lender Parties and/or certain other secured parties) may thereafter exercise (x) all voting, corporate and
other rights pertaining to such Investment Property that constitutes Collateral at any meeting of shareholders of the relevant Issuer or Issuers or otherwise and (y) any and all rights of conversion, exchange








 
and subscription and any other rights, privileges or options pertaining to such Investment Property as if it were the absolute owner thereof (including, without limitation, the right to exchange
at its discretion any and all of the Investment Property upon the merger, consolidation, reorganization, recapitalization or other fundamental change in the corporate or other organizational structure of any Issuer, or upon the exercise by any
Grantor or the Collateral Trustee (or the Administrative Agent on behalf of the Secured Parties and/or the Secured Lender Parties and/or certain other secured parties) of any right, privilege or option pertaining to such Investment Property, and in
connection therewith, the right to deposit and deliver any and all of the Investment Property with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as the Requisite Holders or Collateral
Trustee may determine at the direction of the Requisite Holders (or as the Administrative Agent on behalf of the Secured Parties and/or the Secured Lender Parties and/or certain other secured parties may determine), all without liability except to
account for property actually received by it, but the Collateral Trustee shall have no duty to any Grantor to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing. 

(c) Each Grantor hereby authorizes and instructs each Wholly-Owned Issuer of any Investment Property that constitutes Collateral pledged by
such Grantor hereunder to (i) comply with any instruction received by it from the Collateral Trustee in writing that (x) states that an Event of Default has occurred and is continuing and (y) without any other or further instructions
from such Grantor, and each Grantor agrees that each Wholly-Owned Issuer shall be fully protected in so complying, and (ii) during the continuance of an Event of Default, unless otherwise expressly permitted hereby, pay any dividends or other
payments with respect to the Investment Property directly to the Collateral Trustee. 
 6.4 Proceeds to be Turned Over To Collateral
Trustee. In addition to the rights of the Collateral Trustee and the other Secured Parties specified in Section 6.1 hereof with respect to payments of Receivables, if an Event of Default shall occur and be continuing, upon the request of
Requisite Holders or Collateral Trustee (at the direction of the Requisite Holders), all Proceeds constituting Collateral received by any Grantor consisting of cash, checks and other near-cash items shall be held by such Grantor in trust for the
Collateral Trustee and the other Secured Parties, and either (a) segregated from other funds of such Grantor, and shall, forthwith upon receipt by such Grantor, be turned over to the Collateral Trustee in the exact form received by such Grantor
(duly indorsed by such Grantor to the Collateral Trustee, as applicable) or (b) deposited into a Collateral Account (whether or not so required under Section 5.1 hereof). All Proceeds while held by the Collateral Trustee (or by such
Grantor in trust for the Collateral Trustee and the other Secured Parties) shall continue to be held as collateral security for all the Secured Obligations and shall not constitute payment thereof until applied as provided in Section 6.5
hereof. 
 6.5 Application of Proceeds. From and during the continuance of any Event of Default, any monies or Property actually
received by Collateral Trustee pursuant to this Agreement including without limitation in connection with the exercise of any rights or remedies under this Agreement, shall be applied in in the order set forth in Section 9.06 of the Indenture.








 6.6 Code and Other Remedies. If an Event of Default shall occur and be continuing, the
Collateral Trustee, on behalf of the Secured Parties, may exercise, in addition to all other rights and remedies granted to them in this Agreement and in any other instrument or agreement securing, evidencing or relating to the Secured Obligations,
all rights and remedies of a secured party under the UCC or any other Legal Requirement. Without limiting the generality of the foregoing, the Collateral Trustee, without demand of performance or other demand, presentment, protest, advertisement or
notice of any kind (except any notice required by law referred to below) to or upon any Grantor or any other Person (all and each of which demands, presentments, protests, defenses, advertisements and notices are hereby waived), may in such
circumstances (a) forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or
any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker’s board or office of the Collateral Trustee or any other Secured Party or elsewhere upon such terms
and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk, (b) give notice of sole control or any other instruction under any Deposit
Account Control Agreement or other control agreement with any securities intermediary and take any action therein with respect to such Collateral and (c) concurrently with written notice to the applicable Grantor of its intent to exercise
rights and remedies, transfer and register in its name or in the name of its nominee the whole or any part of the Investment Property, to exchange certificates or instruments representing or evidencing Investment Property for certificates or
instruments of smaller or larger denominations, and subject to the notice requirements of Section 6.3 hereof, to exercise the voting and all other rights as a holder with respect thereto, to collect and receive all cash dividends, interest,
principal and other distributions made thereon and to otherwise act with respect to the Investment Property as though the Collateral Trustee was the outright owner thereof. The Collateral Trustee (on behalf of the Secured Parties) or any other
Secured Party shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption
in any Grantor, which right or equity is hereby waived and released provided that individual Holders shall not be permitted to “credit bid” pursuant to Section 363(k), Section 1129(b)(2)(a)(ii) or
otherwise under the Bankruptcy Code (which right to credit bid shall be exercised solely by the Collateral Trustee, at the direction of the Requisite Holders ). Each Grantor further agrees, at the Collateral Trustee’s request, to assemble the
Collateral and make it available to the Collateral Trustee at places which the Collateral Trustee shall reasonably select, whether at such Grantor’s premises or elsewhere. The Collateral Trustee shall apply the net proceeds of any action taken
by it pursuant to this Section 6.6 in accordance with Section 6.5 hereof and only after such application and the payment of all Secured Obligations in full in immediately available funds and after the payment by the Collateral Trustee of
any other amount required by any provision of law, including, without limitation, Section 9-615(a)(3) of the New York Uniform Commercial Code, need the Collateral Trustee account for the surplus, if any, to any Grantor. If any notice of a
proposed sale or other disposition of Collateral shall be required by law, which is not waived under Section 8.3 hereof, such notice shall be deemed reasonable and proper in every case if given at least ten (10) days before such sale or
other disposition (it being understood that a shorter period may also be reasonable given the circumstances). Until the Collateral Trustee is able to effect a sale, lease, or other disposition of Collateral, the Collateral Trustee shall have the
right to hold or use Collateral, or any part thereof, to the extent that it deems appropriate for the purpose of 







 
preserving Collateral or its value or for any other purpose deemed appropriate by the Collateral Trustee. The Collateral Trustee may, if it so elects, seek the appointment of a receiver or keeper
to take possession of Collateral and to enforce any of the Collateral Trustee’s remedies (for the benefit of the Collateral Trustee and the Secured Parties), with respect to such appointment without prior notice or hearing as to such
appointment. Notwithstanding the foregoing, neither the Collateral Trustee nor any of the Secured Parties shall be required to (i) make any demand upon, or pursue or exhaust any of their rights or remedies against, any Grantor, any other
obligor, guarantor, pledgor or any other Person with respect to the payment of the Secured Obligations or to pursue or exhaust any of their rights or remedies with respect to any Collateral therefor or any direct or indirect guarantee thereof,
(ii) marshal the Collateral or any guarantee of the Secured Obligations or to resort to the Collateral or any such guarantee in any particular order, or (iii) effect a public sale of any Collateral. Notwithstanding any provisions set forth
in Section 6.6 hereof, the Collateral Trustee shall not be required to take any action or use its discretion under this Section 6.6, and the Collateral Trustee shall not take any such action, in each case, other than at the direction of
the Requisite Holders and any discretion by Collateral Trustee under this Section 6.6 shall be the discretion of the Requisite Holders. 

6.7 Sale of Equity Interests. (a) Reserved. 

(b) Each Grantor recognizes that the Collateral Trustee may, in connection with Collateral Trustee’s exercise of its rights and remedies
during the continuation of an Event of Default, exercise its right to sell Pledged Equity in one or more sales thereof to purchasers that would otherwise satisfy the requirements of the Securities Act (for the purposes of this Section 6.7, such
sale a “Private Sale”). Each Grantor acknowledges and agrees that any such Private Sale may result in prices and other terms less favorable than if such sale were of Pledged Equity registered under the provisions of the Securities
Act and, notwithstanding such circumstances or any other circumstances, agrees that no such Private Sale shall be deemed to have been made in a commercially unreasonable manner solely because the Pledged Equity had not been registered under the
provisions of the Securities Act. In no circumstances shall the Collateral Trustee be under any obligation to register Pledged Equity under the provisions of the Securities Act, even if such Issuer would agree to do so nor shall the Collateral
Trustee be under any obligation to delay a sale of any of the Pledged Equity for the period of time necessary to permit the Issuer thereof to register such securities for public sale. 

(c) Each Grantor agrees to use its reasonable efforts to do or cause to be done all such other acts as may be necessary to make such sale or
sales of all or any portion of the Pledged Equity pursuant to this Section 6.7 valid and binding and in compliance with any and all other applicable Legal Requirements. Each Grantor further agrees that a breach of any of the covenants contained
in this Section 6.7 will cause irreparable injury to the Collateral Trustee and the other Secured Parties, that the Collateral Trustee and the other Secured Parties have no adequate remedy at law in respect of such breach and, as a consequence,
that each and every covenant contained in this Section 6.7 shall be specifically enforceable against such Grantor, and such Grantor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants
except for a defense that no Event of Default has occurred under the Indenture. 







 6.8 Grantor’s Obligations Upon Default. Upon the request of the Collateral Trustee
(at the direction of the Requisite Holders) after the occurrence and during the continuance of an Event of Default, each Grantor will: 

(a) assemble and make available to the Collateral Trustee the Collateral and all books and records relating thereto at any place or places
specified by the Collateral Trustee, whether at a Grantor’s premises or elsewhere; and 
 (b) subject in all cases to any lease or
sub-lease agreements and any collateral access agreements, permit the Collateral Trustee, by the Collateral Trustee’s representatives and agents, to enter, occupy and use any premises where all or any part of the Collateral, or the books and
records relating thereto, or both, are located, to take possession of all or any part of the Collateral or the books and records relating thereto, or both, to remove all or any part of the Collateral or the books and records relating thereto, or
both, and to conduct sales of the Collateral, without any obligation to pay the Grantor for such use and occupancy. 
 6.9 Grant of
Intellectual Property License. For the sole purpose of enabling the Collateral Trustee to exercise the rights and remedies under this Agreement at such time as the Collateral Trustee shall be lawfully entitled to exercise such rights and
remedies during the continuance of an Event of Default, each Grantor hereby (a) grants to the Collateral Trustee, for the benefit of the Secured Parties, a nonexclusive license (exercisable without payment of royalty or other compensation to
any Grantor) to use, license or sublicense, on such terms and conditions as the Collateral Trustee shall reasonably determine, any Intellectual Property (other than Excluded Property) and, in the case of Trademarks prior to the acceleration of the
Obligations, subject to sufficient rights to quality control and inspection in favor of such Grantor to avoid the risk of invalidation of said Trademarks, rights now owned or hereafter acquired by such Grantor, and wherever the same may be located,
and including in such license access to all media in which any of the licensed items may be recorded or stored and to all computer software and programs used for the compilation or printout thereof and (b) subject to reasonable quality control
prior to the acceleration of the Obligations, irrevocably agrees that, at any time and from time to time following the occurrence and during the continuance of an Event of Default, the Collateral Trustee may sell any of such Grantor’s Inventory
directly to any person, including without limitation persons who have previously purchased the Grantor’s Inventory from such Grantor and in connection with any such sale or other enforcement of the Collateral Trustee’s rights under this
Agreement, may (subject to any restrictions contained in applicable third-party licenses entered into by a Grantor) sell Inventory which bears any Trademark owned by or licensed to such Grantor and any Inventory that is covered by any Copyright
owned by or licensed to such Grantor and the Collateral Trustee may finish any work in process and affix any Trademark owned by or licensed to such Grantor and sell such Inventory as provided herein. The use of the licenses granted pursuant to
clauses (a) and (b) of the preceding sentence to the Collateral Trustee may be exercised only upon the occurrence and during the continuance of an Event of Default; provided, however, that if any assignment or other transfer
to the Collateral Trustee of any rights, title and interests in and to the Intellectual Property shall have been previously made and shall have become absolute and effective and the Secured Obligations shall not have become immediately due and
payable, upon the written request of any Grantor, to the extent that no Default or Event of Default is then continuing, the Collateral Trustee shall promptly execute and deliver to such Grantor, at such Grantor’s sole cost and expense, such








 
assignments, terminations, or other transfers as may be necessary to reassign to such Grantor and terminate any such rights, title and interests as may have been assigned to the Collateral
Trustee as aforesaid, subject to any disposition thereof that may have been made by the Collateral Trustee; provided, after giving effect to such reassignment, the Collateral Trustee’s security interest granted pursuant hereto, as well as all
other rights and remedies of the Collateral Trustee granted hereunder, shall continue to be in full force and effect. Notwithstanding any provisions set forth in Section 6.9 hereof, the Collateral Trustee shall not be required to take any
action or use its discretion under this Section 6.9, and the Collateral Trustee shall not take any such action, in each case, other than at the direction of the Requisite Holders (other than with respect to the action(s) referenced in the last
sentence of this Section 6.9 hereof) and any discretion by Collateral Trustee under this Section 6.9 shall be the discretion of the Requisite Holders. 

6.10 Subordination Each Grantor hereby agrees that, upon the occurrence and during the continuance of an Event of Default, unless
otherwise agreed by the Collateral Trustee (at the direction of the Requisite Holders), all Indebtedness owing by it to, or to it by, any Grantor shall be fully subordinated to the indefeasible payment in full in cash of the Secured Obligations and
all Indebtedness owing by it to any Subsidiary of Grantor shall be fully subordinated to the indefeasible payment in full in cash of the Secured Obligations. 

6.11 Deficiency. Each Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the
Collateral are insufficient to pay the Secured Obligations (including, without limitation, the fees and disbursements of any attorneys employed by the Collateral Trustee or any other Secured Party to collect such deficiency). 

SECTION 7. THE COLLATERAL TRUSTEE 
 7.1
Collateral Trustee’s Appointment as Attorney-in-Fact, etc. (a) Each Grantor hereby irrevocably constitutes and appoints the Collateral Trustee and any officer or agent thereof, with full power of substitution, as its true and lawful
attorney-in-fact with full irrevocable power and authority in the place and stead of such Grantor and in the name of such Grantor or in its own name, for the purpose of carrying out the terms of this Agreement, to take any and all appropriate action
and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Agreement, and, without limiting the generality of the foregoing, each Grantor hereby gives the Collateral Trustee the power
and right, on behalf of such Grantor, without notice to or assent by such Grantor, to do any or all of the following: 
 (i)
in the name of such Grantor or its own name, or otherwise, take possession of and indorse and collect any checks, drafts, notes, acceptances or other instruments for the payment of moneys due under any Receivable that constitutes Collateral with
respect to any other Collateral and file any claim or take any other action or proceeding in any court of law or equity or otherwise deemed appropriate by the Collateral Trustee for the purpose of collecting any and all such moneys due under any
Receivable that constitutes Collateral or with respect to any other Collateral whenever payable; 







 (ii) in the case of (A) any Intellectual Property that constitutes
Collateral, execute and deliver, and have recorded, any and all agreements, instruments, documents and papers as the Collateral Trustee may request to evidence the Collateral Trustee’s and the other Secured Parties’ security interest in
such Intellectual Property and the goodwill and general intangibles of such Grantor relating thereto or represented thereby and (B) in the case of any insurance, obtain any insurance and pay any insurance premiums with respect to such insurance
called for by the terms of this Agreement or the Indenture (including, but not limited to Section 4.05 of the Indenture) but only to the extent not obtained and maintained by any Grantor; 

(iii) pay or discharge taxes and Liens levied or placed on or threatened against the Collateral, effect any repairs called for
by the terms of this Agreement and pay all or any part of costs thereof; 
 (iv) to prepare and file any UCC financing

 (v) execute, in connection with any sale provided for in Sections 6.6 or

(vi) direct any party liable for any payment under any of the Collateral to make payment of any and all moneys due or to become
due thereunder directly to the Collateral Trustee or as the Collateral Trustee shall direct; ask or demand for, collect, and receive payment of and receipt for, any and all moneys, claims and other amounts due or to become due at any time in respect
of or arising out of any Collateral; sign and indorse any invoices, freight or express bills, bills of lading, storage or warehouse receipts, drafts against debtors, assignments, verifications, notices and other documents in connection with any of
the Collateral; commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any portion thereof and to enforce any other right in respect of any Collateral; defend
any suit, action or proceeding brought against such Grantor with respect to any Collateral; settle, compromise or adjust any such suit, action or proceeding and, in connection therewith, give such discharges or releases as the Collateral Trustee may
deem appropriate; assign any Copyright, Patent or Trademark (along with the goodwill of the business to which any such Copyright, Patent or Trademark pertains), throughout the world for such term or terms, on such conditions, and in such manner, as
the Collateral Trustee shall in its sole discretion determine; and generally, sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Collateral Trustee were
the absolute owner thereof for all purposes, and do, at the Collateral Trustee’s option and such Grantor’s expense, at any time, or from time to time, all acts and things which the Collateral Trustee deems necessary to protect, preserve or
realize upon the Collateral and the Collateral Trustee’s and the other Secured Parties’ security interests therein and to effect the intent of this Agreement, all as fully and effectively as such Grantor might do; and 







 (vii) TO ACT AS ITS PROXY AND ATTORNEY-IN-FACT (AS SET FORTH IN SECTION 7.1
ABOVE) WITH RESPECT TO ITS INVESTMENT PROPERTY, INCLUDING, SUBJECT TO SECTION 6.3 HEREOF, THE RIGHT TO VOTE SUCH INVESTMENT PROPERTY, WITH FULL POWER OF SUBSTITUTION TO DO SO. IN ADDITION TO THE RIGHT TO VOTE ANY SUCH INVESTMENT PROPERTY, THE
APPOINTMENT OF THE ADMINISTRATIVE AGENT AS PROXY AND ATTORNEY-IN-FACT SHALL INCLUDE, SUBJECT TO SECTION 6.3 HEREOF, THE RIGHT TO EXERCISE ALL OTHER RIGHTS, POWERS, PRIVILEGES AND REMEDIES TO WHICH A HOLDER OF SUCH INVESTMENT PROPERTY, WOULD BE
ENTITLED (INCLUDING GIVING OR WITHHOLDING WRITTEN CONSENTS OF SHAREHOLDERS, CALLING SPECIAL MEETINGS OF SHAREHOLDERS AND VOTING AT SUCH MEETINGS). SUCH PROXY SHALL BE EFFECTIVE, AUTOMATICALLY AND WITHOUT THE NECESSITY OF ANY ACTION (INCLUDING ANY
TRANSFER OF ANY SUCH INVESTMENT PROPERTY ON THE RECORD BOOKS OF THE ISSUER THEREOF) BY ANY PERSON (INCLUDING THE ISSUER OF SUCH INVESTMENT PROPERTY OR ANY OFFICER OR AGENT THEREOF). 

Anything in this Section 7.1(a) to the contrary notwithstanding, the Collateral Trustee agrees that it will not, and is not authorized
to, exercise any rights under the power of attorney provided for in this Sections 7.1(a) (other than Sections 7.1(a)(ii)(A) and 7.1(a)(iv)) unless an Event of Default shall have occurred and be continuing. 

(b) If any Grantor fails to perform or comply with any of its agreements contained in this Agreement, the Collateral Trustee shall, at the
direction of the Requisite Holders, perform or comply, or otherwise cause performance or compliance, with such agreement. 
 (c) The
expenses of the Collateral Trustee incurred in connection with actions undertaken as provided in this Section 7.1, together with interest thereon at a rate per annum equal to the rate per annum at which interest would then be payable on the
Notes, from the date of payment by the Collateral Trustee to the date reimbursed by the Grantors, shall be payable by Grantors to the Collateral Trustee on demand, or directly out of Proceeds from any relevant Collateral, at the Collateral
Trustee’s discretion. 
 (d) Each Grantor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue
hereof. All powers, authorizations and agencies contained in this Agreement are coupled with an interest and are irrevocable until this Agreement is terminated and the security interests created hereby are released. 

(e) Notwithstanding any provisions set forth in Section 7.1 hereof, the Collateral Trustee shall not be required to take any action or
use its discretion under this Section 7.1, and the Collateral Trustee shall not take any such action, in each case, other than at the direction of the Requisite Holders and any discretion by Collateral Trustee under this Section 7.1 shall
be the discretion of the Requisite Holders. 







 7.2 Duty of Collateral Trustee. The Collateral Trustee’s sole duty with respect to
the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9-207 of the New York Uniform Commercial Code or otherwise, shall be to deal with it in the same manner as the Collateral Trustee deals with
similar property for its own account. Neither the Collateral Trustee, any other Secured Party nor any of their respective representatives, successors, assigns, affiliates, partners, members, investors, shareholders, attorneys, officers, directors,
employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Grantor or
any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The powers, rights and discretionary duties conferred on the Collateral Trustee and the other Secured Parties hereunder are solely to protect
the Collateral Trustee’s and the other Secured Parties’ interests in the Collateral and shall not impose any duty upon the Collateral Trustee or any other Secured Party to exercise any such powers. The Collateral Trustee and the other
Secured Parties shall be accountable only for amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their representatives, successors, assigns, affiliates, partners, members, investors,
shareholders, attorneys, officers, directors, employees or agents shall be responsible to any Grantor for any act or failure to act hereunder, except for their own gross negligence, bad faith or willful misconduct as finally determined by a court of
competent jurisdiction. To the extent that any Legal Requirement imposes duties on the Collateral Trustee to exercise remedies in a commercially reasonable manner, each Grantor acknowledges and agrees that it may be commercially reasonable for the
Collateral Trustee (i) to fail to incur expenses deemed significant by the Collateral Trustee to prepare Collateral for disposition or otherwise to transform raw material or work in process into finished goods or other finished products for
disposition, (ii) to fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by any Legal Requirement, to fail to obtain governmental or third party consents for the collection or
disposition of Collateral to be collected or disposed of, (iii) to fail to exercise collection remedies against Account Debtors or other Persons obligated on Collateral or to remove Liens on or any adverse claims against Collateral,
(iv) to exercise collection remedies against Account Debtors and other Persons obligated on Collateral directly or through the use of collection agencies and other collection specialists, (v) to advertise dispositions of Collateral through
publications or media of general circulation, whether or not the Collateral is of a specialized nature, (vi) to contact other Persons, whether or not in the same business as such Grantor, for expressions of interest in acquiring all or any
portion of such Collateral, (vii) to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the Collateral is of a specialized nature, (viii) to dispose of Collateral by utilizing internet
sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capacity of doing so, or that match buyers and sellers of assets, (ix) to dispose of assets in wholesale rather than retail
markets, (x) to disclaim disposition warranties, such as title, possession or quiet enjoyment, (xi) to purchase insurance or credit enhancements to insure the Secured Parties against risks of loss, collection or disposition of Collateral
or to provide to the Secured Parties a guaranteed return from the collection or disposition of Collateral, or (xii) to the extent deemed appropriate by the Collateral Trustee, to obtain the services of other brokers, investment bankers,
consultants and other professionals to assist the Collateral Trustee in the collection or disposition of any of the Collateral. Each Grantor acknowledges that the purpose of this Section 7.2 is to provide non-exhaustive 







 
indications of what actions or omissions by the Collateral Trustee may be commercially reasonable in the Collateral Trustee’s exercise of remedies against the Collateral and that other
actions or omissions by the Collateral Trustee shall not be deemed commercially unreasonable solely on account of not being indicated in this Section 7.2. Without limitation upon the foregoing, nothing contained in this Section 7.2 shall
be construed to grant any rights to any Grantor or to impose any duties on the Collateral Trustee that would not have been granted or imposed by this Agreement or by any Legal Requirement in the absence of this Section 7.2. Notwithstanding any
provisions set forth in Section 7.2 hereof, the Collateral Trustee shall not be required to take any action or use its discretion under this Section 7.2, and the Collateral Trustee shall not take any such action, in each case, other than
at the direction of the Requisite Holders and any discretion by Collateral Trustee under this Section 7.2 shall be the discretion of the Requisite Holders. 

7.3 Execution of Financing Statements and Other Documents. Pursuant to any applicable law, each Grantor authorizes the Collateral
Trustee to file or record financing statements and other filing or recording documents or instruments with respect to the Collateral without the signature of such Grantor in such form and in such offices as the Requisite Holders or Collateral
Trustee reasonably determines appropriate to perfect the security interests of the Collateral Trustee under this Agreement and, if applicable, to maintain Control of Collateral. Each Grantor authorizes the Collateral Trustee to use the collateral
description “all assets now existing or hereafter acquired” or “all personal property now existing or hereafter acquired” or any similar collateral description in any such financing statements. Each Grantor hereby ratifies and
authorizes the filing by the Collateral Trustee (or on its behalf) of any financing statement with respect to the Collateral made prior to the date hereof; provided that such authorization will not impose any such duty upon the Collateral Trustee.
Nothing in this Section 7.3 shall relieve any Grantor from its obligation to file financing statements, to file any continuation statements or to otherwise maintain perfection of the Collateral Trustee’s security interest as such
obligations are set forth in this Agreement, the Indenture or any other document provided that once financing statement(s) are filed for the benefit of Collateral Trustee, Grantors shall not amend, modify, supplement or terminate such financing
statement(s) without the prior written consent of the Collateral Trustee (acting at the direction of the Requisite Holders) or the Requisite Holders. 

7.4 Secured Party Performance of Debtor Obligations. Without having any obligation to do so, the Collateral Trustee may, after the
occurrence and during the continuance of an Event of Default, perform or pay any obligation which any Grantor has agreed to perform or pay in this Agreement but failed to perform or pay and the Grantors shall reimburse the Collateral Trustee for any
amounts paid by the Collateral Trustee pursuant to this Section 7.4. The Grantors’ obligation to reimburse the Collateral Trustee pursuant to the preceding sentence shall be a Secured Obligation payable on demand, or directly out of
Proceeds from any relevant Collateral, at the Collateral Trustee’s discretion. Notwithstanding any provisions set forth in Section 7.4 hereof, the Collateral Trustee shall not be required to take any action or use its discretion under this
Section 7.4, and the Collateral Trustee shall not take any such action, in each case, other than at the direction of the Requisite Holders and any discretion by Collateral Trustee under this Section 7.4 shall be the discretion of the
Requisite Holders. 







 7.5 Specific Performance of Certain Covenants. Each Grantor acknowledges and agrees that
an Event of Default that has occurred and is continuing as a result of a breach of any of the covenants contained in Sections 4, 5, 6.1, 6.2, 6.3, 6.4, 6.7 and 6.8 hereof will cause irreparable injury to the Secured Parties, that the Collateral
Trustee and the other Secured Parties have no adequate remedy at law in respect of such Events of Default and therefore agrees, without limiting the right of the Collateral Trustee or the Secured Parties to seek and obtain specific performance of
other obligations of the Grantors contained in this Agreement, that the covenants of the Grantors contained in the Sections referred to in this Section 7.5 shall, to the extent permitted under applicable law, be specifically enforceable against
the Grantors. 
 7.6 Authority of Collateral Trustee. Each Grantor acknowledges that the rights and responsibilities of the
Collateral Trustee under this Agreement with respect to any action taken by the Collateral Trustee or the exercise or non-exercise by the Collateral Trustee of any option, voting right, request, judgment, discretionary duty or other right or remedy
provided for herein or resulting or arising out of this Agreement shall, as between the Collateral Trustee and the other Secured Parties, be governed by the Indenture and by such other agreements with respect thereto as may exist from time to time
among them, but, as between the Collateral Trustee and the Grantors, the Collateral Trustee shall be conclusively presumed to be acting as agent for the Secured Parties with full and valid authority so to act or refrain from acting, and no Grantor
shall be under any obligation, or entitlement, to make any inquiry respecting such authority. 
 7.7 Protections of Collateral
Trustee. (a) For all purposes of this Agreement, the Collateral Trustee shall not be deemed to have notice or knowledge of any Event of Default or matter hereunder unless written notice of such event is received by the Collateral Trustee
conspicuously specifying that an Event of Default has occurred and is continuing or an officer of the Collateral Trustee responsible for the administration of this Agreement has actual knowledge thereof. 

(b) Except for action expressly required hereunder (which does not include circumstances in which the Collateral Trustee has the ability but
not an affirmative duty to act) or in the Indenture, nothing in this Agreement, the Indenture or any Security Document shall be interpreted as giving the Collateral Trustee responsibility for or any duty concerning the validity, perfection, priority
or enforceability of any Lien or security interest in any Collateral or giving the Collateral Trustee any obligation to take any action to procure or maintain such validity, perfection, priority or enforceability. 

(c) Neither the Collateral Trustee nor any of its representatives, successors, assigns, partners, members, investors, shareholders, attorneys,
affiliates, directors, officers, agents or employees shall be liable for any action taken or not taken by it in connection herewith (i) with the consent or at the request of a Person authorized hereunder, the Intercreditor Agreement or under
the Indenture or (ii) in the absence of its own gross negligence or willful misconduct as finally determined by a court of competent jurisdiction. Neither the Collateral Trustee nor any of its representatives, successors, assigns, partners,
members, investors, shareholders, attorneys, affiliates, directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into or verify (i) any statement, warranty or representation made in connection
with this Agreement; (ii) the performance or observance of any of the covenants or agreements of a Grantor; (iii) the receipt of items required to be 







 
delivered to the Collateral Trustee; or (iv) the validity, effectiveness or genuineness of this Agreement, the other Security Documents or any other instrument or writing furnished in
connection herewith. The Collateral Trustee shall not incur any liability by acting in reliance upon any notice, consent, certificate, statement, or other writing (which may be a bank wire, telex or similar writing) reasonably believed by it to be
genuine or to be signed by the proper party or parties. The Collateral Trustee shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement or any other Security Document or any other document furnished in
connection herewith or therewith in accordance with a written direction or a request of an authorized Person pursuant to the terms of this Agreement or the Indenture. 

(d) Reserved. 
 (e) In entering
into this Agreement, and in taking (or refraining from) any actions under or pursuant to this Agreement, the Collateral Trustee shall be protected by and shall enjoy all of the rights, immunities, protections and indemnities granted to it under the
Intercreditor Agreement, the Indenture or the Security Documents. 
 SECTION 8. MISCELLANEOUS 

8.1 Amendments in Writing. None of the terms or provisions of this Agreement may be waived, amended, supplemented or otherwise modified
other than pursuant to an amendment executed by the Collateral Trustee (at the direction of the Requisite Holders or, if the consent of all Holders would be required to so modify the Indenture pursuant to Section 14.02 of the Indenture, at the
direction of all of the Holders) and each of the Grantors. 
 8.2 Notices. All notices, requests and demands to or upon the
Collateral Trustee or any Grantor hereunder shall be effected in the manner provided for in Section 16.02 of the Indenture. 
 8.3
Waivers. To the extent permitted under applicable law, each Grantor hereby waives notice of the time and place of any public sale or the time after which any private sale or other disposition of all or any part of the Collateral may be made.
To the extent such notice may not be waived under applicable law, any notice made shall be deemed reasonable if sent to the Grantors, addressed as set forth in Section 8.2 hereof, at least ten (10) days prior (or such shorter period as may
be commercially reasonable) to (i) the date of any such public sale or (ii) the time after which any such private sale or other disposition may be made. To the maximum extent permitted by applicable law, each Grantor waives all claims,
damages, and demands against the Collateral Trustee or any Secured Party arising out of the exercise of any rights and/or remedies hereunder, including, without limitation, the repossession, retention or sale of the Collateral, except such as arise
out of the gross negligence, bad faith or willful misconduct of the Collateral Trustee or such Secured Party as finally determined by a court of competent jurisdiction. To the extent it may lawfully do so, each Grantor absolutely and irrevocably
waives and relinquishes the benefit and advantage of, and covenants not to assert against the Collateral Trustee or any Secured Party, any valuation, stay, appraisal, extension, moratorium, redemption or similar laws and any and all rights or
defenses it may have as a surety now or hereafter existing which, but for this provision, might be applicable to the sale of any Collateral made under the judgment, order or decree of any court, or privately under the power of 







 
sale conferred by this Agreement, or otherwise. Except as otherwise specifically provided herein, each Grantor hereby waives presentment, demand, protest or any notice (to the maximum extent
permitted by applicable law) of any kind in connection with this Agreement or any Collateral. 
 8.4 No Waiver by Course of Conduct;
Cumulative Remedies. Neither the Collateral Trustee nor any other Secured Party shall by any act (except by a written instrument pursuant to Section 8.1 hereof), delay, indulgence, omission or otherwise be deemed to have waived any right or
remedy hereunder or to have acquiesced in any Default or Event of Default. No failure to exercise, nor any delay in exercising, on the part of the Collateral Trustee or any other Secured Party, any right, power or privilege hereunder shall operate
as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Collateral Trustee or any
other Secured Party of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Collateral Trustee or such other Secured Party would otherwise have on any future occasion. The rights and
remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law. 

8.5 Enforcement Expenses; Indemnification. (a) Each Grantor agrees to pay or reimburse the Collateral Trustee and each other
Secured Party for their respective reasonable out-of-pocket costs and expenses incurred in enforcing or preserving any rights under this Agreement and the other Security Documents to which such Grantor is a party, including, without limitation, the
reasonable fees and disbursements of counsel to the Collateral Trustee, in each case, to the same extent the Company would be required to do so pursuant to Section 11.07 of the Indenture and/or pursuant to the Purchase Agreement. 

(b) Each Grantor agrees to pay, and to indemnify and save the Collateral Trustee and the other Secured Parties harmless from, any and all
liabilities with respect to, or resulting from any delay in paying, any and all stamp, excise, sales or other taxes which may be payable or determined to be payable with respect to any of the Collateral or in connection with any of the transactions
contemplated by this Agreement. 
 (c) Each Grantor agrees to pay, and to indemnify and save the Collateral Trustee and the other Secured
Parties harmless from, any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to the execution, delivery, enforcement, performance
and administration of this Agreement to the same extent the Company would be required to do so pursuant to Sections 6.03, 11.07 and 11.16 of the Indenture. 

(d) The agreements in this Section 8.5 shall survive repayment (and the Exchange) of the Secured Obligations and all other amounts
payable under the Indenture and the Security Documents. 
 8.6 Successors and Assigns. This Agreement shall be binding upon the
successors and assigns of each Grantor and shall inure to the benefit of the Collateral Trustee and the other Secured Parties and their successors and assigns; provided that no Grantor may assign, transfer or delegate any of its rights or
obligations under this Agreement without the prior written consent of the Collateral Trustee and the Holders. 







 8.7 Counterparts. This Agreement may be executed by one or more of the parties to this
Agreement on any number of separate counterparts (including by telecopy, .pdf, or other electronic transmission), and all of said counterparts taken together shall be deemed to constitute one and the same instrument. 

8.8 Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable
such provision in any other jurisdiction. 
 8.9 Section Headings. The Section headings used in this Agreement are for
convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof. 

8.10 Integration. This Agreement, the Indenture, the other Security Documents and the other Indenture Documents represent the
agreement of the Grantors, the Collateral Trustee and the other Secured Parties with respect to the subject matter hereof and thereof, and there are no promises, undertakings, representations or warranties by the Collateral Trustee or any other
Secured Party relative to subject matter hereof and thereof not expressly set forth or referred to herein or in the Indenture, the other Security Documents and the other Indenture Documents. 

8.11 Reinstatement. This Agreement shall remain in full force and effect and continue to be effective should any petition be filed by
or against any Grantor for liquidation or reorganization, should any Grantor become insolvent or make an assignment for the benefit of any creditor or creditors, should a receiver or trustee be appointed for all or any significant part of any
Grantor’s assets, or any similar proceeding is initiated or undertaken and shall continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Secured Obligations, or any part thereof, is, pursuant
to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee of the Secured Obligations, whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, all as though such
payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Secured Obligations shall be reinstated and deemed reduced only by such amount paid and not so rescinded,
reduced, restored or returned. 
 8.12 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL
BE CONSTRUED IN ACCORDANCE WITH AND BE GOVERNED BY THE LAW OF THE STATE OF NEW YORK. 







 8.13 Submission To Jurisdiction; Waivers. Each Grantor hereby irrevocably and
unconditionally: 
 (a) submits for itself and its property in any legal action or proceeding relating to this Agreement and the other
Security Documents to which it is a party, or for recognition and enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the Courts of the State of New York, the courts of the United States of America for the
Southern District of New York, and appellate courts from any thereof; 
 (b) consents that any such action or proceeding may be brought in
such courts and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

 (c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified
mail (or any substantially similar form of mail), postage prepaid, to such Grantor at its address referred to in Section 8.2 hereof; 

(d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the
right to sue in any other jurisdiction; and 
 (e) waives, to the maximum extent not prohibited by law, any right it may have to claim or
recover in any legal action or proceeding referred to in this Section any special, exemplary, punitive or consequential damages. 

8.14 Acknowledgements. Each Grantor hereby acknowledges that: 

(a) it has been advised by counsel in the negotiation, execution and delivery of this Agreement and the other Security Documents to which it
is a party; 
 (b) neither the Collateral Trustee nor any other Secured Party has any fiduciary relationship with or duty to any Grantor
arising out of or in connection with this Agreement or any of the other Security Documents, and the relationship between the Grantors, on the one hand, and the Collateral Trustee and other Secured Parties, on the other hand, in connection herewith
or therewith is solely that of debtor and creditor; and 
 (c) no joint venture is created hereby or by the other Security Documents or
otherwise exists by virtue of the transactions contemplated hereby among the Secured Parties or among the Grantors and the Secured Parties. 

8.15 WAIVER OF JURY TRIAL. EACH OF THE GRANTORS AND THE COLLATERAL TRUSTEE HEREBY ACKNOWLEDGES THAT IT HAS BEEN REPRESENTED BY AND
HAS CONSULTED WITH COUNSEL OF ITS CHOICE, AND HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY, AND IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN RESPECT OF ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE
TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY) EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY
WOULD NOT, IN THE EVENT OF LITIGATION SEEK TO 







 
ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS IN THIS SECTION. 
 8.16 Additional Grantors. Each Subsidiary of the Company that is required to become a party
to this Agreement pursuant to Sections 4.21 and 4.41 of the Indenture shall become a Grantor for all purposes of this Agreement upon execution and delivery by such Subsidiary of an Assumption Agreement in the form of Annex 1 hereto. 

8.17 Releases. Collateral shall be automatically released from the Lien created by this Agreement to the extent provided in
Section 5.07 of the Indenture. 
 8.18 Intercreditor Agreement; Subordination Agreement. This Agreement shall be subject in all
respects to the Intercreditor Agreement and Subordination Agreement. Notwithstanding anything herein to the contrary, the security interest and lien granted pursuant to this Agreement and the exercise of any right or remedy hereunder are subject to
the provisions of the Intercreditor Agreement and the Subordination Agreement. In the event of any conflict between the terms of this Agreement and the Intercreditor Agreement, the terms of the Intercreditor Agreement shall govern and control at any
time the Intercreditor Agreement is in effect. In the event of any conflict between the terms of this Agreement and the Subordination Agreement, the terms of the Subordination Agreement shall govern and control at any time the Subordination
Agreement is in effect. So long as any Person is acting as bailee and as agent for perfection on behalf of the Collateral Trustee pursuant to the terms of the Intercreditor Agreement or the Subordination Agreement, any obligation of any Grantor in
this Agreement that requires delivery of Collateral to, or the possession or control of Collateral with, the Collateral Trustee shall be deemed complied with and satisfied if such delivery of Collateral is made to, or such possession or control of
Collateral is with, such person acting as bailee and as agent for perfection (for Collateral Trustee) in accordance with the terms of the Intercreditor Agreement and Subordination Agreement.

 WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute and
deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall become a Guarantor (as defined in the Indenture); 

WHEREAS, Section 14.01(iii) of the Indenture provides that the Company, the Guarantors and the Trustee may amend or supplement the
Indenture in order to add any additional Guarantor with respect to the Notes, without the consent of the Holders of the Notes; and 

WHEREAS, all acts and things prescribed by the Indenture, by law and by the Certificate of Incorporation and the Bylaws (or comparable
constituent documents) of the Company, of the Guarantors and of the Trustee necessary to make this Supplemental Indenture a valid instrument legally binding on the Company, the Guarantors and the Trustee, in accordance with its terms, have been duly
done and performed; 
 NOW, THEREFORE, to comply with the provisions of the Indenture and in consideration of the above premises, the
Company, the Guaranteeing Subsidiary, the other Guarantors and the Trustee covenant and agree for the equal and proportionate benefit of the respective Holders of the Notes as follows:
