 INDENTURE, dated as of July 22, 2014, between Energy & Exploration Partners, Inc.,

For and in consideration of the premises and the purchase of the Notes by the Holders (each as defined below), each party agrees as follows
for the benefit of the other party and for the equal and ratable benefit of the Holders of the Company’s 8.00% Convertible Subordinated Notes due 2019: 

ARTICLE 1 
 DEFINITIONS
AND OTHER PROVISIONS OF GENERAL APPLICATION 
 Section 1.01 Definitions. 

“Acquired Debt” means, with respect to any specified Person: (i) Indebtedness of any other Person existing at the time
such other Person is merged with or into or became a Subsidiary of such specified Person, whether or not such Indebtedness is incurred in connection with, or in contemplation of, such other Person merging with or into, or becoming a Subsidiary of,
such specified Person, and (ii) Indebtedness secured by a Lien encumbering any asset acquired by such specified Person. 

“Affiliate” means, with respect to any specified Person, any other Person who directly or indirectly through one or more
intermediaries controls or is controlled by, or is under common control with such specified Person. The term “control” means the possession, directly or indirectly, of the power to direct or cause the direction of the management and
policies of a Person, whether through the ownership of voting securities, by contract or otherwise; and the terms “controlling” and “controlled” have meanings correlative of the foregoing. 

“Applicable Procedures” means, with respect to any transfer or transaction involving a Global Note or any beneficial interest
therein, the rules and procedures of the Depositary, Euroclear and Clearstream for such Note, in each case to the extent applicable to such transfer or transaction and as in effect from time to time. 

“Attributable Debt” in respect of a sale and leaseback transaction means, at the time of determination, the present value of
the obligation of the lessee for net rental payments during the remaining term of the lease included in such sale and leaseback transaction including any period for which such lease has been extended or may, at the option of the lessor, be extended.
Such present value shall be calculated using a discount rate equal to the rate of interest implicit in such transaction, determined in accordance with GAAP. As used in the preceding sentence, the ‘‘net rental payments’’ under any
lease for any such period shall mean the sum of rental and other payments required to be paid with respect to such period by the lessee thereunder, excluding any amounts required to be paid by such lessee on account of maintenance and repairs,
insurance, taxes, assessments, water rates or similar charges. In the case of any lease that is terminable by the lessee upon payment of penalty, such net rental payment shall also include the amount of such penalty, but no rent shall be considered
as required to be paid under such lease subsequent to the first date upon which it may be so terminated. 

  
 - 1 - 








 “Bankruptcy Law” means Title 11, United States Code, or any similar U.S.
federal, state or non-U.S. bankruptcy, insolvency, receivership or similar law for the relief of debtors. 
 “Board of
Directors” means: 
 (1) with respect to a corporation, the board of directors of the corporation or any committee thereof
duly authorized to act on behalf of such board; 
 (2) with respect to a partnership, the board of directors of the general partner of the
partnership; 
 (3) with respect to a limited liability company, the managing member or members or any controlling committee of managing
members thereof; and 
 (4) with respect to any other Person, the board or committee of such Person serving a similar function. 

“Board Resolution” means a copy of one or more resolutions certified by the Secretary or an Assistant Secretary of the
Company to have been duly adopted by its Board of Directors and to be in full force and effect on the date of such certification, and delivered to the Trustee. 

“Business Day” means any day other than a Saturday, a Sunday or a day on which the Federal Reserve Bank of New York or banks
in the city where the applicable place of payment is located is authorized or required by law or executive order to close or be closed. 

“Capital Lease Obligation” means, at the time any determination thereof is to be made, the amount of the liability of a
Person in respect of a capital lease that would at that time be required to be capitalized on a balance sheet of such Person in accordance with GAAP. 

“Capital Stock” means: 

(1) in the case of a corporation, corporate stock; 

(2) in the case of an association or business entity, any and all shares, interests, participations, rights or other equivalents (however
designated) of corporate stock; 
 (3) in the case of a partnership or limited liability company, partnership interests (whether general or
limited) or membership interests; and 
 (4) any other interest or participation that confers on a Person (as defined below) the right to
receive a share of the profits and losses of, or distributions of assets of, the issuing Person, but excluding from all of the foregoing any debt securities convertible into Capital Stock, whether or not such debt securities include any right of
participation with Capital Stock. 
 “Certificated Notes” means Notes that are in registered certificated form. 

  
 - 2 - 








 “Change of Control” means the occurrence at any time after the Notes are
originally issued of any of the following: 
 (1) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than
by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the properties or assets of the Company and the Subsidiaries taken as a whole to any Person (including any “person” (as that
term is used in Section 13(d)(3) of the Exchange Act)) other than any Permitted Holder; 
 (2) the adoption of a plan relating to the
liquidation or dissolution of the Company; or 
 (3) the consummation of any transaction (including, without limitation, any merger or
consolidation), the result of which is that any Person (including any “person” (as defined above)), other than any Permitted Holder, becomes the Beneficial Owner (as defined below), directly or indirectly, of more than 50% of the Voting
Stock of the Company, measured by voting power rather than number of shares, membership interests, units or the like. 
 Notwithstanding the
preceding, a conversion of a Person from a limited liability company, corporation, limited partnership or other form of entity to a limited liability company, corporation, limited partnership or other form of entity or an exchange of all of the
outstanding Capital Stock in one form of entity for Capital Stock in another form of entity shall not constitute a Change of Control, so long as following such conversion or exchange the “persons” (as that term is used in
Section 13(d)(3) of the Exchange Act) who Beneficially Owned the Capital Stock of the Company immediately prior to such transactions continue to Beneficially Own in the aggregate more than 50% of the Voting Stock of such entity, or continue to
Beneficially Own sufficient Capital Stock in such entity to elect a majority of its directors, managers, trustees or other persons serving in a similar capacity for such entity, and, in either case no “person,” other than any Permitted
Holder, Beneficially Owns more than 50% of the Voting Stock of such entity. 
 For purposes of this definition, the term “Beneficial
Owner” has the meaning assigned to such term in Rule 13d-3 and Rule 13d-5 under the Exchange Act, except that in calculating the beneficial ownership of any particular “person” (as that term is used in Section 13(d)(3) of the
Exchange Act), such “person” will be deemed to have beneficial ownership of all securities that such “person” has the right to acquire by conversion or exercise of other securities, whether such right is currently exercisable or
is exercisable only after the passage of time. The terms “Beneficially Own” and “Beneficially Owned” have a corresponding meaning. Notwithstanding the foregoing, holders of the Company’s Equity Interests that are parties to
the Stockholders Agreement shall not be deemed to be a “person” pursuant to Section 13(d)(3) solely by reason of the fact that they are parties to or bound by the terms of the Stockholders Agreement. 

“Change of Control Date” means the effective date of a Change of Control. 

“Clearstream” means Clearstream Banking, S.A. 

“Close of Business” means 5:00 p.m., New York City time. 

“Closing Date Equity Value” means the aggregate fair market value of the outstanding shares of Common Stock immediately
following an Equity Sale (and, for the avoidance of doubt, after giving effect to such Equity Sale) (determined based on the sale price per share of Common Stock in the Equity Sale or, in the case of an Equity Sale involving Convertible Securities,
the effective sale price per share of Common Stock after taking into consideration the purchase price

“Company” means the party named as such in the first paragraph of this Indenture until a successor or assignee replaces it

“Company Order” means a written request or order signed in the name of the Company by any Officer. 

“Corporate Trust Office” means the designated office of the Trustee at which at any time its corporate trust business shall
be administered, which office at the date hereof is located at 13737 Noel Road, Suite 800, Dallas, Texas 75240, or such other address as the Trustee may designate from time to time by written notice to the Holders, the Paying Agent, the Conversion
Agent, the Registrar and the Company, or the designated corporate trust office of any successor Trustee (or such other address as such successor Trustee may designate from time to time by written notice to the Holders, the Paying Agent, the
Conversion Agent, the Registrar and the Company). 
 “Credit Facilities” means one or more debt facilities,
indentures or commercial paper facilities (including, without limitation, the Term Loan), in each case with banks or other institutional lenders, providing for revolving credit loans, term loans, capital market financings, private placements,
receivables financings (including through the sale of receivables to such lenders or to special purpose entities formed to borrow from such lenders against such receivables) or letters of credit or letter of credit guarantees, in each case, as
amended, restated, modified, supplemented, extended, renewed, refunded, replaced or refinanced in whole or in part from time to time.

Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of Holders signing such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent will be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section 1.04.

entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company will have no obligation to do so. If such a record date is fixed, such request, demand,


  
 - 16 - 








 
authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the Close of Business on such record date will be
deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of outstanding Notes have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act,
and, for that purpose, the outstanding Notes will be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date will be deemed effective unless it will become effective
pursuant to the provisions of this Indenture not later than six months after the record date.

exchange for, or in lieu of, other Notes pursuant to Sections 2.09, 2.11, 2.12 and 3.06 hereof. In addition, the Company may issue an unlimited aggregate principal amount of additional Notes in accordance with Section 2.01(b) hereof. 

(b) Without the consent of any Holder, and notwithstanding anything to the contrary in Sections 2.01(a) or 2.05 hereof, the Company may
increase the aggregate principal amount of the Notes issued under this Indenture by reopening this Indenture and issuing additional Notes with the same terms as the initial Notes (except, to the extent applicable, with respect to the date as of
which interest shall begin to accrue on such additional Notes), which Notes will, subject to the foregoing, be considered to be part of the same series of Notes as those initially issued hereunder; provided, however, that if any such
additional Notes are not fungible with other Notes issued hereunder for federal income tax purposes, then such additional Notes shall have a separate CUSIP number. Prior to issuing any such additional Notes, the Company will deliver to the Trustee a
Company Order, an Officers’ Certificate and an Opinion of Counsel, which Officers’ Certificate and Opinion of Counsel will (i) address any matters required to be addressed under Section 13.03 hereof, (ii) include a statement
that the form and the terms of such Notes has been established in conformity with the provisions of this Indenture and (iii) include a statement that the Notes when authenticated and delivered by the Trustee and issued by the Company in the
manner and subject to any conditions specified in such Officers’ Certificate or Opinion of Counsel, will constitute valid and legally binding obligations of the Company, enforceable in accordance with their terms, subject to bankruptcy,
insolvency, reorganization and other laws of general applicability relating to or affecting the enforcement of creditors’ rights and to general equity principles.  

Section 2.02 Form of Notes. 

(a) General. The Notes will be substantially in the form of Exhibit A hereto, but may include any notations, legends or
endorsements required by any applicable law (or regulation promulgated thereunder), stock exchange rule, agreement to which the Company is subject or usage, or any insertions, omissions or other variations otherwise permitted or required by this
Indenture. Whenever any such notation, legend or endorsement, or any such insertion, omission or other variation is applicable to a Note, the Company will provide such notation, legend or endorsement, or such insertion, omission or other variation
to the Trustee in writing. 

  
 - 17 - 








 Each Note will bear a Trustee’s certificate of authentication substantially in the form set
forth in Exhibit A hereto. 
 Notes that are Global Notes will bear the Global Note Legend and the “Schedule of Increases and
Decreases of Global Note” attached thereto. 
 Notes will bear the Restricted Notes Legend. 

The terms and provisions contained in the Notes will constitute, and are hereby expressly made, a part of this Indenture and, to the extent
applicable, the Company and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent that any provision of any Note conflicts with the express
provisions of this Indenture, the provisions of this Indenture will govern and control. 
 (b) Initial and Subsequent Notes.
The Notes initially will be issued in global form, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee, at its Corporate Trust Office, as custodian for the Depositary. Except to the extent
provided in Section 2.09(c) hereof, all Notes will be represented by one or more Global Notes. 
 (c) Global Notes.
Each Global Note will represent the aggregate principal amount of then outstanding Notes endorsed thereon and provide that it represents such aggregate principal amount of then outstanding Notes, which aggregate principal amount may, from time
to time, be reduced or increased to reflect transfers, exchanges, conversions, redemptions or repurchases by the Company. 
 Only the
Trustee, or the custodian holding such Global Note for the Depositary at the direction of the Trustee, may endorse a Global Note and/or, in the case of the Trustee, adjust the balance on the Register in accordance with its internal procedures, to
reflect the amount of any increase or decrease in the aggregate principal amount of then outstanding Notes represented thereby, and whenever the Holder of a Global Note delivers instructions to the Trustee to increase or decrease the aggregate
principal amount of then outstanding Notes represented by a Global Note in accordance with Section 2.09 hereof, the Trustee, or the custodian holding such Global Note for the Depositary, at the direction of the Trustee, will endorse such Global
Note and/or, in the case of the Trustee, adjust the balance of the Register in accordance with its internal procedures, to reflect such increase or decrease in the aggregate principal amount of then outstanding Notes represented thereby. None of the
Trustee, the Company or any agent of the Trustee or the Company will have any responsibility or bear any liability for any aspect of the records relating to, or payments made on account of, the ownership of any beneficial interest in a Global Note
or with respect to maintaining, supervising or reviewing any records relating to such beneficial interest. 
 Neither any member of, or
participant in, the Depositary, Euroclear or Clearstream (collectively, the “Agent Members”) nor any other Person on whose behalf an Agent Member may act will have any rights under this Indenture with respect to any Global Note or
under such Global Note, and the Company, the Trustee and any agent of the Company or the Trustee, may, for all purposes, treat the Depositary, or its nominee, if any, as the absolute owner and Holder of such Global Note. 

  
 - 18 - 








 The Holder of a Global Note may grant proxies and otherwise authorize any Person, including Agent
Members and Persons that may hold interests through Agent Members, to take any action that such Holder is entitled to take under this Indenture or the Notes with respect to such Global Note, and, notwithstanding the foregoing, nothing herein will
prevent the Company, the Trustee, the Paying Agent or any agent of the Company, the Trustee or the Paying Agent from giving effect to any written certification, proxy or other authorization furnished by such Holder or impair, as between the
Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act, the operation of their respective customary practices governing the exercise of the rights of a Holder of any interest in any Global Note. 

Neither the Trustee nor any of the Paying Agent, Registrar, Conversion Agent or any other agent of the Trustee shall have any responsibility
or liability for the payment of amounts to owners of beneficial interests in a Global Note for any aspect of the records relating to or payments made on account of those interests by the Depositary or for maintaining, supervising or reviewing any
records of the Depositary relating to those interests. 
 Section 2.03 Denomination of Notes. The Notes will be issuable
in minimum denominations of $1,000.00 principal amount and in integral multiples of $1,000 in excess thereof. 
 Section 2.04
Payments. 
 (a) General. 

(i) Terminal Value Payment at Maturity or Upon Certain Events. Unless earlier converted, redeemed or repurchased pursuant to any of
Sections 3.05(c), 11.03 or 12.07 hereof, the Notes will mature on July 1, 2019 (the “Maturity Date”). On the Maturity Date, each Holder will be entitled to, and the Company will pay or cause the Paying Agent to pay each Holder,
a cash amount equal to the product of (w) the principal amount of Notes held by such Holder on the Maturity Date and (x) the Applicable Premium as of the Maturity Date (calculated pursuant to Section 3.01(b) as if the Maturity Date
was the Change of Control Date for purposes of that calculation), together with all accrued and unpaid interest on such Notes to, but not including, the Maturity Date. In addition, notwithstanding anything in this Indenture to the contrary, in the
event of the liquidation, dissolution or winding up of the Company, including, without limitation, any such event constituting an Event of Default specified in Section 6.01(a)(ix) (but not, for the avoidance of doubt, any such event complying
with Section 5.01), each Holder will be entitled to, and the Company will pay or cause the Paying Agent to pay each Holder, a cash amount equal to the product of (y) the principal amount of Notes held by such Holder on the effective date
of such event and (z) the Applicable Premium as of such effective date (calculated pursuant to Section 3.01(b) as if such effective date was the Change of Control Date for purposes of that calculation), together with all accrued and unpaid
interest on such Notes to, but not including, such effective date. The amount payable under this Section 2.04(a)(i) is referred to herein as the “Terminal Value.” 

  
 - 19 - 








 (ii) Payment of Interest. Each Note will accrue interest at a rate (the “Interest
Rate”) equal to 8.00% per annum from the most recent date to which interest has been paid or duly provided for, or, if no interest has been paid or duly provided for, the Issue Date (or such other date provided for in
Section 2.01(b) with respect to Notes issued in accordance with such Section) until, subject to the provisions of Section 2.04(c), the date the principal amount of such Note is converted, paid or deemed paid, as the case may be, pursuant
to clause (i) of this Section 2.04(a) or any of Sections 3.05, 11.03 or 12.07 hereof; provided that the Interest Rate on the Notes will increase by 0.50% per annum effective as of the Interest Payment Date falling on
July 1, 2015 and on each Interest Payment Date thereafter (a “Scheduled Interest Rate Increase”) if a preliminary prospectus under the Securities Act with a bona fide price range in connection with a Qualified PO has not been
filed by each such Interest Payment Date and, in each case, such Qualified PO has not priced within 60 days after the date of such Scheduled Interest Rate Increase. The Company shall notify the Trustee of such Scheduled Interest Rate Increase in an
Officers’ Certificate. 
 Interest will be payable semi-annually in arrears on January 1 and July 1 of each year (each, an
“Interest Payment Date”), beginning January 1, 2015 (or such other date provided for in Section 2.01(b) with respect to Notes issued in accordance with such Section), to the Holder of each such Note as of the Close of
Business (whether or not a Business Day) on the December 15 or June 15, as the case may be, immediately preceding the relevant Interest Payment Date (each such date, a “Regular Record Date”). Interest will be computed on
the basis of a 360-day year comprised of twelve 30-day months. 
 Interest accruing on the Notes will be payable on each Interest Payment
Date entirely in cash. 
 (iii) Method of Payment. The Company will pay or cause the Paying Agent to pay any principal or Terminal
Value of, Change of Control Repurchase Price or Redemption Price for, and interest on, any Global Note to the Depositary by wire transfer of immediately available funds on the relevant payment date. 

The Company will pay or cause the Paying Agent to pay any principal or Terminal Value of, Change of Control Repurchase Price or Redemption
Price for, and interest on any Certificated Note in cash to the applicable Holder of such Note at the office of the Paying Agent on the relevant payment date or, at the option of the Company, through the Paying Agent by check mailed to the Holder of
such Note at its address set forth in the register of Holders. 
 The Company will pay or cause the Paying Agent to pay interest due on an
Interest Payment Date on any Certificated Note (i) to any Holder of an aggregate principal amount of Notes less than or equal to $5,000,000, by check mailed to such Holder’s registered address, and (ii) to any Holder of an aggregate
principal amount of Notes greater than $5,000,000, either by check mailed to such Holder’s registered address or, upon application by such Holder to the Registrar not later than five days prior to the Regular Record Date relating to such
Interest Payment Date, a written request to the Registrar that the Company makes such payments by wire transfer to an account of such Holder within the United States, by wire transfer of immediately available funds to such account, which request
shall remain in effect until such Holder notifies, in writing, the Registrar to the contrary. 

  
 - 20 - 








 If any Interest Payment Date, the date for payment of amounts in respect of conversions, the
Maturity Date or a Change of Control Repurchase Date falls on a day that is not a Business Day, the required payment will be made on the next succeeding Business Day and no interest on such payment will accrue as a result of such delay. 

(b) Interest Rights Preserved. Subject to the provisions of Section 2.04(c) hereof, and, to the extent applicable, Sections 2.09
and 2.11 hereof, each Note delivered under this Indenture upon registration of transfer of, or in exchange for, or in lieu of, any other Note will carry any rights to the payment and accrual of interest that were carried by the relevant surrendered
Note, Notes or portion(s) thereof. 
 (c) Defaulted Amounts. Whenever any principal or interest payable on a Note (including any
Change of Control Repurchase Price, Redemption Price or Terminal Value, if applicable) has become due and payable on the Maturity Date, upon repurchase, redemption or declaration of acceleration or otherwise, but the Company fails to punctually pay
or duly provide for such amount (any such amount, a “Defaulted Amount”), such Defaulted Amount will forthwith cease to be payable to the Holder of such Note on the relevant payment date by virtue of its having been due such payment
on such payment date, but will instead, to the extent permitted under applicable law, accrue interest (“Default Interest”) at a rate equal to the then prevailing Interest Rate plus 1% per annum from, and including, such payment
date and to, but excluding, the date on which such Defaulted Amount is paid by the Company in accordance with either clause (i) or (ii) below. 

(i) The Company may elect to pay any Defaulted Amount and Default Interest on such Defaulted Amount to the Persons in whose names the Notes
(or their respective predecessor Notes) are registered at the Close of Business on a special record date for the payment of such Defaulted Amount and Default Interest (a “Special Record Date”) fixed in accordance with the following
procedures: 
 (A) At least 30 days before the date on which the Company proposes to pay such Defaulted Amounts and Default
Interest thereon, the Company will deliver to the Trustee written notice in the form of an Officers’ Certificate of (I) the proposed payment date for such Defaulted Amounts and Default Interest thereon and (II) the aggregate amount of such
Defaulted Amounts and Default Interest thereon. 
 (B) Simultaneously with delivering such notice to the Trustee, the Company
will either (I) deposit with the Trustee an amount of money, in immediately available funds, equal to the aggregate amount of such Defaulted Amounts and Default Interest thereon, or (II) take other actions that the Trustee deems reasonably
satisfactory to ensure that an amount of money, in immediately available funds, equal to the aggregate of such Defaulted Amounts and Default Interest thereon will be deposited with the Trustee by 10:00 a.m., New York City time, on the proposed
payment date, and in either case, upon receipt of such money, the Trustee will hold such money in trust for the benefit of the Persons entitled to such Defaulted Amounts and Default Interest pursuant to this Section 2.04(c)(i). 

  
 - 21 - 








 (C) Upon (i) receipt of such notice and (ii) the Company’s
depositing such money or taking such other actions reasonably satisfactory to the Trustee, the Company will promptly fix a Special Record Date for the payment of such Defaulted Amounts and Default Interest thereon, which Special Record Date will be
not more than 15 calendar days and not less than 10 days prior to the proposed payment date, and notify the Trustee in writing of the Special Record Date. The Trustee will then, in the name and at the expense of the Company, deliver notice to each
Holder specifying such Special Record Date and the date on which such Defaulted Amounts and Default Interest thereon will be paid by the Company. 

(D) After such notice has been delivered by the Trustee, such Defaulted Amounts and Default Interest thereon will be paid to
the Persons in whose names the Notes (or their respective predecessor Notes) are registered at the Close of Business on the Special Record Date specified in such notice and such Defaulted Amounts and Default Interest thereon will no longer be
payable pursuant to the following clause (ii) of this Section 2.04(c)(i). 
 (ii) The Company may pay any Defaulted Amounts and
Default Interest on such Defaulted Amounts in any other lawful manner that is not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes are then listed (or, if applicable, have been approved
for listing) or designated for issuance, and upon such notice as may be required by such exchange or automated quotation system, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of
payment will be deemed practicable by the Trustee. For the avoidance of doubt, the Trustee shall not at any time be under any duty or responsibility to any Holder to determine the Defaulted Amounts or Default Interest, or with respect to the nature,
extent, or calculation of the amount of Defaulted Amounts or Default Interest owed, or with respect to the method employed in such calculation of the Defaulted Amounts or Default Interest. 

Section 2.05 Execution and Authentication. 

(a) In General. A Note will be valid only if executed by the Company and authenticated by the Trustee. 

(b) Execution. A Note will be deemed to have been executed by the Company when an Officer of the Company signs such Note on behalf of
the Company. Each Officer’s signature may be manual or facsimile, and the validity of such Officer’s signature will not depend on whether such signatory remains an Officer at the time the Trustee authenticates such Note. 

(c) Authentication. A Note will be deemed authenticated when an authorized signatory of the Trustee manually signs the certificate of
authentication on such Note. An authorized signatory of the Trustee will manually sign the certificate of authentication on a Note only if (i) the Company delivers such Note to the Trustee, (ii) such Note is validly executed by the Company
in accordance with Section 2.05(b) hereof, and (iii) the Company delivers, before or with such Note, a Company Order setting forth (A) a request that the Trustee authenticate such Note; (B) the principal amount of such Note;
(C) the name of the Holder of such Note; and (D) the date on which such Note is to be authenticated. If the Company Order also specifies that the Trustee must deliver such Note to the Holder or the Depositary, the Trustee will promptly
deliver such Note in accordance with such Company Order. 

  
 - 22 - 








 The Trustee may appoint an authenticating agent reasonably acceptable to the Company and at the
expense of the Company. If the Trustee appoints an authenticating agent, such authenticating agent may authenticate a Note whenever the Trustee may authenticate such Note, unless limited by the terms of such appointment. Each reference in this
Indenture to authentication by the Trustee will be deemed to include authentication by an authenticating agent, and an authenticating agent will have the same rights to deal with the Company as the Trustee would have if it were performing the duties
that the authentication agent was validly appointed to undertake. 
 Section 2.06 Registrar, Paying Agent and Conversion
Agent. 
 (a) General. The Company will maintain an office or agency in the continental United States where Notes may be
presented for registration of transfer or for exchange (the “Registrar”), an office or agency where the Notes may be presented for payment, repurchase or redemption (the “Paying Agent”), an office or agency where
the Notes may be presented for conversion (the “Conversion Agent”) and an office or agency where notices and demands with respect to the Notes and this Indenture may be served. 

The Registrar will keep a register for the recordation of, and will record, the names and addresses of Holders, the Notes held by each
Holder and the transfer, exchange, repurchase, redemption and conversion of Notes (the “Register”). Absent manifest error, the entries in the Register will be conclusive and the parties may treat each Person whose name is recorded
in the Register pursuant to the terms hereof as a Holder hereunder for all purposes of this Indenture. The Register will be in written form or in any form capable of being converted into written form within a reasonably prompt period of time.

 The Company may have one or more Registrars, one or more Paying Agents, one or more Conversion Agents and one or more places where
notices and demands with respect to the Notes and this Indenture may be served. Before appointing any Registrar, Paying Agent or Conversion Agent that is not otherwise a party to this Indenture, the Company will enter into an appropriate agency
agreement with such Registrar, Paying Agent or Conversion Agent, as the case may be, which agency agreement will implement the provisions of this Indenture that relate to such replacement or additional Registrar, Paying Agent or Conversion Agent, as
the case may be. The term Registrar includes any additional registrars named pursuant to this Indenture. The term Paying Agent includes any additional paying agent named pursuant to this Indenture. The term Conversion Agent includes any additional
conversion agent named pursuant to this Indenture. Upon the occurrence of any Event of Default under Section 6.01(a)(ix) or 6.01(a)(x) with respect to the Company, the Trustee shall be the Paying Agent. 

(b) Initial Designations. The Company initially appoints the Trustee as each of the Registrar, the Paying Agent and the
Conversion Agent, and the Notes initially may be presented for registration of transfer or for exchange, payment, repurchase, redemption and conversion to the Trustee, in its capacity as the Registrar, Paying Agent or Conversion Agent, as the case
may be, at the Corporate Trust Office. Notices and demands with respect to the Notes and this Indenture may be served at the Corporate Trust Office. 

  
 - 23 - 








 (c) Removal, Resignation and Replacement. The Company may remove any Registrar,
Paying Agent or Conversion Agent by delivering written notice to the Trustee and to such Registrar, Paying Agent or Conversion Agent; provided, however, that no such removal will become effective unless (i) after such removal, at
least one Registrar, Paying Agent and Conversion Agent will remain; (ii) a successor has accepted appointment as Registrar, Paying Agent or Conversion Agent, as the case may be, the Company and such successor have entered into an agency
agreement in accordance with Section 2.06(a) hereof, and the Company has delivered written notice of such appointment and a copy of such agency agreement to the Trustee; or (iii) the Company has delivered written notice to the Trustee that
the Trustee will serve as the successor Registrar, Paying Agent or Conversion Agent, as the case may be, in accordance with Section 2.06(d) hereof; and provided, further, that the right to effect any such change or removal in no
way relieves the Company of its obligation to maintain a Registrar, Paying Agent and Conversion Agent in the continental United States. The Company may also change the place where notices and demands with respect to the Notes and this Indenture may
be served, or reduce the number of such places; provided, however, that the right to effect any such change or reduction in no way relieves the Company of its obligation to maintain a place in the continental United States where
notices and demands with respect to the Notes and this Indenture may be served. 
 In addition, the Registrar, Paying Agent or
Conversion Agent may resign at any time by delivering written notice of such resignation to each of the Company and the Trustee; provided, however, that if the Trustee is serving as Registrar, Paying Agent or Conversion Agent, the
Trustee may resign from such capacity only if it also resigns as Trustee in accordance with Section 7.07 hereof. If, after any such resignation, at least one Registrar, Paying Agent and Conversion Agent does not remain, the Trustee will
immediately be deemed to serve such empty office or agency in accordance with Section 2.06(d) hereof. 
 (d) Failure
to Maintain an Office or Agency. If the Company fails to maintain, in the continental United States, a Registrar, Paying Agent, Conversion Agent or place where notices and demands with respect to the Notes and this Indenture may be served, the
Trustee will act as the Registrar, Paying Agent, Conversion Agent, or place, as the case may be, and the office where the Notes may be presented for registration of transfer or for exchange, presented for payment, repurchase or redemption or
surrendered for conversion, or place where notices and demands with respect to the Notes and this Indenture may be served, as the case may be, will be the Corporate Trust Office. In each such case, the Trustee will be entitled to compensation for
such action pursuant to Section 7.06 hereof. 
 (e) Notices. Promptly upon the effectiveness of any removal or
appointment of a Registrar, Paying Agent or Conversion Agent, or upon any change in the location of the office of any Registrar, Paying Agent or Conversion Agent, or of the place where notices and demands with respect to the Notes and this Indenture
may be served, the Company will deliver to each Holder written notice of such removal, appointment or change in location, as the case may be, which notice will include a brief description of the removal, appointment or change in location, as the
case may be, and list the name and address of each continuing (and newly appointed, if applicable) Registrar, Paying Agent and Conversion Agent and place where notices and demands with respect to the Notes and this Indenture may be served.

 Section 2.07 Money Held in Trust. Except as otherwise provided herein, by no later
than 10:00 a.m., New York City time, on each due date for a payment on any Note, the Company will deposit with the Paying Agent an amount of money in immediately available funds, if deposited on the due date sufficient to make such payment when due.

 The Company will require that each Paying Agent (other than the Trustee, if the Trustee is a Paying Agent) agree in writing that it will
(i) segregate all money it holds for making payments with respect to the Notes; (ii) hold such money in trust for the benefit of Holders; and (iii) notify the Trustee, in writing, as promptly as practicable, if the Company defaults in
making any payment on the Notes. 
 If any such default has occurred and is continuing, the Paying Agent will, upon receiving a written
request from the Trustee, forthwith pay to the Trustee all of the money it holds in trust. In addition, at any time, the Company may require a Paying Agent to pay all money that it holds for making payments with respect to the Notes to the Trustee
and to account for any money it has disbursed. After delivering all of such money to the Trustee pursuant to this Section 2.07, the Paying Agent (in its capacity as such) will have no further liability for such money. 

Section 2.08 Holder Lists. 

The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of
Holders. If the Trustee is not the Registrar, the Company will furnish to the Trustee, (i) within five Business Days after each Regular Record Date, a list of the names and addresses of Holders as of such Regular Record Date and (ii) at
such other times as the Trustee may request in writing, within 30 days after receipt by the Company of such request, a list of the names and addresses of Holders as of no more than 15 days immediately prior to the date such list is furnished, in
each case, in such form as the Trustee may reasonably require. 
 Section 2.09 Transfer and Exchange. 

(a) Provisions Applicable to All Transfers and Exchanges. 

(i) Subject to the restrictions set forth in this Section 2.09 and Section 11.02(f), Certificated Notes and beneficial interests in
Global Notes may be transferred or exchanged from time to time as desired, and each such transfer or exchange of Certificated Notes will be noted by the Registrar in the Register. 

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

(iii) No service charge will be imposed by the Company, the Trustee or the Registrar on any Holder of a Certificated Note or any owner of a
beneficial interest in a Global 

  
 - 25 - 








 
Note for any exchange or registration of transfer, but each of the Company, the Trustee or the Registrar may require such Holder or owner of a beneficial interest to pay a sum sufficient to cover
any transfer tax, assessment or other similar governmental charge required by law or permitted by this Indenture. 
 (iv) None of the
Company, the Trustee, the Registrar or any co-registrar will be required to exchange or register a transfer of any Note (i) surrendered for conversion, except to the extent that any portion of such Note has not been surrendered for conversion,
(ii) subject to a Change of Control Repurchase Notice validly delivered pursuant to Section 3.03 hereof, except to the extent any portion of such Note is not subject to a Change of Control Repurchase Notice or the Company fails to pay the
applicable Change of Control Repurchase Price when due, or (iii) after the Company has delivered a Redemption Notice pursuant to Section 12.04 hereof, except to the extent the Company fails to pay the applicable Redemption Price when due.

 (v) The Trustee will have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on Transfer
imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depositary participants or beneficial owners of interests in any Global Note) other than to
require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of this Indenture, and to examine the same to determine substantial compliance as to
form with the express requirements hereof. 
 (b) In General; Transfer and Exchange of Beneficial Interests in Global Notes. So long
as the Notes are eligible for book-entry settlement with the Depositary (unless otherwise required by law and except to the extent required by Section 2.09(c) hereof): 

(i) all Notes will be represented by one or more Global Notes; 

(ii) every transfer and exchange of a beneficial interest in a Global Note will be effected through the Depositary in accordance with the
Applicable Procedures and the provisions of this Indenture (including the restrictions on Transfer set forth in Section 2.10 hereof); and 

(iii) each Global Note may be transferred only as a whole and only (A) by the Depositary to a nominee of the Depositary, (B) by a
nominee of the Depositary to the Depositary or to another nominee of the Depositary, or (C) by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. 

(c) Transfer and Exchange of Global Notes for Certificated Notes. 

(i) Notwithstanding any other provision of this Indenture, each Global Note will be exchanged for Certificated Notes if the Depositary
delivers notice to the Company that: 
 (I) the Depositary is unwilling or unable to continue to act as Depositary; or 

  
 - 26 - 








 (II) the Depositary is no longer registered as a clearing agency under the Exchange Act, 

and, in each case, the Company promptly delivers a copy of such notice to the Trustee and the Company fails to appoint a successor Depositary within 90 days
after receiving notice from the Depositary. 
 In each such case, (1) each Global Note will be deemed surrendered to the Trustee for
cancellation, (2) the Trustee will promptly cancel each such Global Note in accordance with the Applicable Procedures, (3) the Company, (x) in accordance with Section 2.05 hereof, will promptly execute, for each beneficial
interest in each Global Note so cancelled, an aggregate principal amount of Certificated Notes equal to the aggregate principal amount of such beneficial interest, registered in such name and authorized denominations as the Depositary specifies, and
bearing such legends as such Certificated Notes are required to bear under Section 2.02 and Section 2.10 hereof, and, (y) as provided in Section 2.05(c) hereof, will promptly deliver to the Trustee such Certificated Notes and a
Company Order including the information specified in Section 2.05(c) hereof with respect to such Certificated Notes, and (4) the Trustee, upon receipt of such Certificated Notes and such Company Order, in accordance with Section 2.05
hereof, will promptly authenticate, and deliver to the Holder specified in such Company Order, such Certificated Notes. 
 (ii) In addition:

 (I) if an Event of Default has occurred and is continuing, any owner of a beneficial interest in a Global Note may exchange such
beneficial interest for Certificated Notes by delivering a written request to the Company, the Registrar and the Trustee; or 
 (II) at any
time, the Company may, in its sole discretion, at the request of the owner of a beneficial interest in a Global Note, permit the exchange of such owner’s beneficial interest for Certificated Notes, by delivering a written request to the
Registrar, the Trustee and the owner of such beneficial interest. 
 In each case, (1) upon receipt of such request, the Registrar will
promptly deliver written notice of such request to the Company and the Trustee, which notice must identify the owner of the beneficial interest to be exchanged, the aggregate principal amount of such beneficial interest and the CUSIP number of the
relevant Global Note; (2) the Trustee, upon receipt of such notice, will promptly cause the aggregate principal amount of such Global Note to be reduced by the aggregate principal amount of the beneficial interest to be so exchanged in
accordance with the Applicable Procedures, (3) the Company (x) in accordance with Section 2.05 hereof, will promptly execute, for such beneficial interest, a Certificated Note having aggregate principal amount equal to the aggregate

Clearstream (as indirect participants in the Depositary), unless transferred to a Person that takes delivery through Global Notes being offered and sold to qualified institutional buyers in reliance on Rule 144A (“Rule 144A Global
Notes”) in accordance with the certification requirements described in this Indenture. Beneficial interests in the Rule 144A Global Notes may not be exchanged for beneficial interests in the Regulation S Global Notes at any time except in

Company and the Trustee deem sufficient in their judgment to protect each of them from any loss that it may suffer upon replacement of such Note, and, in either case, (b) such Holder satisfies any other reasonable requirements of the Trustee,

hereof, will promptly authenticate and deliver, in the name of such Holder, a replacement Note having the same aggregate principal amount as the Note that was mutilated or claimed to be lost, destroyed or stolen, bearing any restrictive legends
required by Section 2.02 or 2.10 hereof and with a certificate number not contemporaneously outstanding. 

  
 - 31 - 








 Every new Note issued pursuant to this Section 2.11 in exchange for any mutilated Note, or

denomination, and substantially in the form of Certificated Notes, but with such omissions, insertions and variations as may be appropriate for Temporary Notes, all as may be determined by the Company. Every such Temporary Note will be executed by
the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Certificated Notes. Without unreasonable delay the Company will prepare,
execute and deliver to the Trustee or such authenticating agent Certificated Notes (other than any Global Note) and thereupon any or all Temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency
maintained by the Company pursuant to Section 2.06 hereof and the Trustee or such authenticating agent will authenticate and deliver in exchange for such Temporary Notes Certificated Notes having an aggregate principal amount equal to such
Temporary Notes. Such exchange will be made by the Company at its own expense and without any charge therefor. Until so exchanged, the Temporary Notes will, in all respects, be entitled to the same benefits and subject to the same limitations under
this Indenture as Certificated Notes authenticated and delivered hereunder. 
 Section 2.13 Cancellation. At any time, the
Company may deliver Notes to the Trustee for cancellation. Whenever any Note is surrendered to the Registrar, Conversion Agent or Paying Agent for registration of transfer, exchange, conversion, repurchase, redemption or payment, the Registrar,
Conversion Agent or Paying Agent, as the case may be, will promptly forward such Note to the Trustee. Upon receipt of any such Note, the Trustee, in its customary manner, will promptly cancel and dispose of such Note. The Company may not issue new
Notes to replace Notes that the Company has repurchased, redeemed, paid or delivered to the Trustee for cancellation or that a Holder has converted pursuant to Article 11 hereof. 

Section 2.14 Outstanding Notes. At any time, Notes outstanding are limited to all Notes authenticated by the Trustee except
(i) those cancelled by it, (ii) those delivered to it for cancellation and (iii) those deemed not outstanding under Sections 3.05, 11.02 and 12.07 hereof and clauses (a) and (b) of this Section 2.14.

 - 32 - 








 (b) In addition, if the Company, any other obligor or an Affiliate of the Company or an Affiliate
of such other obligor holds a Note, such Note will be disregarded and deemed not to be outstanding for purposes of determining whether the Holders of the requisite aggregate principal amount of Notes have given or concurred in any request, demand,
authorization, direction, notice, consent, waiver or other action hereunder, except that, solely in determining whether the Trustee shall have any liability in making a determination as to which Notes are outstanding, only Notes which a Responsible
Officer actually knows to be so owned shall be disregarded. Subject to the foregoing, only Notes outstanding at the time of any such determination will be considered in such determination (including determinations pursuant to Article 6 and Article 9
hereof). 
 Section 2.15 Persons Deemed Owners. Prior to due presentment of a Note for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Note is registered in the Register as the owner of such Note for the purpose of receiving the payment of any principal or Terminal Value of,
Change of Control Repurchase Price or Redemption Price for, and accrued but unpaid interest on, such Note, for the purpose of conversion of such Note and for all other purposes whatsoever with respect to such Note, and none of the Company, the
Trustee or any agent of the Company or the Trustee will be affected by any notice to the contrary. 
 Section 2.16 Repurchases.
The Company may, from time to time, repurchase Notes in open market purchases or in negotiated transactions without delivering prior notice to Holders. Such repurchased Notes will no longer be outstanding under this Indenture. 

Section 2.17 CUSIP and ISIN Numbers. 

(a) Whenever “CUSIP” and “ISIN” numbers are generally in use, the Company will use CUSIP and ISIN numbers with respect to
the Notes, which CUSIP and ISIN numbers will be restricted numbers. Whenever the Company uses CUSIP and ISIN numbers, the Trustee will also use CUSIP and ISIN numbers in each notice it delivers to the Holders; provided, that neither the
Company nor the Trustee will be responsible for any defect in any CUSIP or ISIN number that appears on any Note, check, advice of payment or notice, including any notice delivered pursuant to Section 12.04. The Company will promptly notify the
Trustee in writing in the event of any change in the CUSIP or ISIN numbers. 
 (b) In addition, if, when any shares of Common Stock are
issued upon conversion of a Note, CUSIP and ISIN numbers are generally in use, the Company will use CUSIP and ISIN numbers with respect to such shares of Common Stock, which CUSIP and ISIN numbers (i) for shares of Common Stock to which the
restrictions on Transfer set forth in the Restricted Stock Legend apply, will be restricted numbers, and (ii) for shares of Common Stock to which the restrictions on Transfer set forth in the Restricted Stock Legend do not apply, will be
unrestricted numbers. 
 (c) Whenever any of the CUSIP or ISIN numbers with respect to the Notes or the shares of Common Stock issuable upon
conversion of the Notes change, cease to be used, or begin to be used, the Company will deliver prompt written notice of such change, cessation, or beginning to each of the Trustee and the Holders.

balancing positions arising in the ordinary course of business;

(i) in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Indebtedness
described in clauses (i) through (xvi) above, the Company will be permitted to classify such item of Indebtedness (or any portion thereof) on the date of its incurrence, subject to clause (ii) below, and may later reclassify such

partially in one such clause and partially in one or more other such clauses; 
 (ii) all Indebtedness outstanding on the date of this

of a particular amount of Indebtedness shall not be included; 
 (iv) if obligations in respect of letters of credit are incurred pursuant

(v) the amount of Indebtedness issued at a price that is less than the principal amount thereof will be equal to the amount of the liability

Disqualified Stock or preferred equity in the form of additional shares of the same class of Disqualified Stock or preferred equity will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock or preferred equity for
purposes of this Section 4.05. 
 (c) For purposes of determining compliance with any U.S. dollar-denominated restriction on the
incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the
case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause
the applicable U.S. dollar-dominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-dominated restriction shall be deemed not to have been exceeded so long
as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that the Company may incur
pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Permitted Refinancing Indebtedness, if incurred in a different currency from the
Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Permitted Refinancing Indebtedness is denominated that is in effect on the date of such refinancing. 

Section 4.06 Taxes. The Company will pay, and will cause each of the Subsidiaries to pay, prior to delinquency, all material
taxes, assessments and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders. 

Section 4.07 Corporate Existence. Subject to Article 5 hereof, the Company will do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence in accordance with its organizational documents (as the same may be amended from time to time). 

Section 4.08 Stay, Extension and Usury Laws. The Company covenants that, to the extent that it may lawfully do so, it will
not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of
this Indenture; and the Company, to the extent that it may lawfully do so, hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any
power herein granted to the Trustee, but will instead suffer and permit the execution of every such power as though no such law has been enacted. 

  
 - 45 - 








 Section 4.09 Further Instruments and Acts. Upon request of the Trustee, the Company
will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the terms of this Indenture. 

Section 4.10 Determination of Equity Value. Whenever the calculation of the Equity Value of the Company is required as of a
specified date, the Company will cause a determination of such Equity Value to be made by three investment banking firms or valuation firms of national reputation (which may include the initial purchasers in the offering of the Notes or the banks
acting as underwriters, initial purchasers, agents or advisors in the transaction triggering the determination) engaged by the Company at its expense. In the event that such firms do not or cannot agree on such Equity Value for the Company, the
Equity Value for the Company shall be equal to the average of the three Equity Values for the Company determined by such firms. Any such determination will be final and binding on the Holders. 

Section 4.11 Issuance of Conversion Shares . In connection with the consummation of a Qualified PO, the Company shall amend its
certificate of incorporation to authorize the maximum number of Conversion Shares issuable upon conversion of the Notes, such Conversion Shares shall be duly and validly authorized and reserved for issuance upon conversion of the Notes, and the
Company shall take such other action as will be necessary to comply with the Company’s obligations set forth in Article XI.

 (b) except in the case of a Reorganization Event that is a conveyance, transfer or
lease of all or substantially all of the Company’s assets, the Person named as the “Company” in the first paragraph of this Indenture or any successor (other than such Reorganization Successor Corporation) that will thereafter have
become such in the manner prescribed in this Article 5 will be released from its obligations under this Indenture and may be dissolved, wound up and liquidated at any time.

 - 49 - 








 
Notes may, on behalf of the Holders of all of the then outstanding Notes, rescind any acceleration of the Notes and its consequences hereunder by delivering written notice to the Trustee if

collect the payment of any principal or Terminal Value of, Change of Control Repurchase Price or Redemption Price for, or accrued and unpaid interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture
regarding any other matter. 
 The Trustee may maintain a proceeding even if it 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 will 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 6.04 Waiver of Past Defaults. If
an Event of Default described in Sections 6.01(a)(i), 6.01(a)(ii), 6.01(a)(iii), Section 6.01(a)(iv) or 6.01(a)(vi) (which, in the case of Section 6.01(a)(vi) only, relates to a covenant that cannot be amended without the consent of each
affected Holder) or a Default that would lead to such an Event of Default occurs and is continuing, such Event of Default or Default may be waived only with the consent of each affected Holder. Every other Event of Default or Default may be waived
by the Holders of a majority of the aggregate principal amount of then outstanding Notes. Whenever any Event of Default is so waived, it will cease to exist, and whenever any Default is so waived, it will be deemed cured and any Event of Default
arising therefrom will be deemed not to occur. However, no such waiver will extend to any subsequent or other Default or Event of Default or impair any consequent right. 

Section 6.05 Control by Majority. At any time, the Holders of a majority of the aggregate principal amount of then outstanding
Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or for exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts
with law or this Indenture or, subject to Section 7.01 hereof, that the Trustee determines to be unduly prejudicial to the rights of a Holder or to the Trustee, or that would potentially involve the Trustee in personal liability unless the
Trustee is offered indemnity or security satisfactory to it against any loss, liability or expense to the Trustee that may result from the Trustee’s instituting such proceeding as the Trustee. Prior to taking any action hereunder, the Trustee
will be entitled to indemnification or security satisfactory to it against all losses, liabilities and expenses caused by taking or not taking such action.

 Section 6.06 Limitation on Suits. Except in the case of an Event of Default described
in Section 6.01(a)(i), 6.01(a)(ii), 6.01(a)(iii) or Section 6.01(a)(iv) hereof, no Holder may pursue a remedy with respect to this Indenture or the Notes unless: 

(a) such Holder has previously delivered to the Trustee written notice that an Event of Default has occurred and is continuing; 

(b) the Holders of at least 25% of the aggregate principal amount of then-outstanding Notes deliver to the Trustee a written request that the
Trustee pursue a remedy with respect to such Event of Default; 
 (c) such Holder or Holders have offered and, if requested, provided, to
the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or other expense of compliance with such written request; 

(d) the Trustee has not complied with such written request within 60 days after receipt of such written request and offer of security or
indemnity; and 
 (e) during such 60-day period, the Holders of a majority of the aggregate principal amount of then outstanding Notes did
not deliver to the Trustee a direction inconsistent with such written request. 
 A Holder may not use this Indenture to prejudice the
rights of any other Holder or to obtain a preference or priority over any other Holder, it being understood that the Trustee does not have any affirmative duty to ascertain whether any usage of this Indenture by a Holder is unduly prejudicial to
such other Holders. 
 Section 6.07 Rights of Holders To Receive Payment. Notwithstanding any other provision of this Indenture,
the right of any Holder to receive payment of the principal or Terminal Value of, the Change of Control Repurchase Price or the Redemption Price, if any, for, the accrued and unpaid interest, if any, on, and any consideration due under Article 11
upon conversion of, its Note, on or after the respective due date, or to bring suit for the enforcement of any such payment and/or delivery on or after the respective due date, will not be impaired or affected without the consent of such Holder and
will not be subject to the requirements of Section 6.06 hereof. 
 Section 6.08 Collection Suit by Trustee. If an Event of
Default specified in Section 6.01(a)(i), 6.01(a)(ii) or 6.01(a)(iii) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company or any Guarantor for the
whole amount of any principal or Terminal Value of, Change of Control Repurchase Price or Redemption Price for, and accrued and unpaid interest on, the Notes, and, to the extent lawful, any Default Interest on any Defaulted Amounts, and such further
amount as is sufficient to cover the costs and expenses of collection provided for under Section 7.06 hereof. 
 Section 6.09
Trustee May File Proofs of Claim. The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable to have the claims of the Trustee and the Holders allowed in any judicial proceedings
relative to the Company or any Guarantor, or the creditors or property of the Company or any Guarantor, and, 

  
 - 51 - 








 
unless prohibited by law or applicable regulations, will be entitled to collect, receive and distribute any money or other property payable or deliverable on any such claims, and any Custodian in
any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee consents to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for
the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 hereof. To the extent that the payment of any such compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 hereof out of the estate in any such proceeding, will be denied for any reason, payment of the same will be secured by a
Lien on, and will be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement
or otherwise. Nothing herein contained will be deemed to authorize the Trustee to authorize or consent to, or to accept or to adopt on behalf of any Holder, any plan of reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

Section 6.10 Priorities . If the Trustee collects any money or property pursuant to this Article 6, it will pay out the money or
property in the following order: 
 FIRST: to the Trustee, its agents and attorneys for amounts due under Section 7.06 hereof,
including payment of all compensation, fees, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

SECOND: to the Holders, for any amounts due and unpaid on the principal or Terminal Value of, the Change of Control Repurchase Price or
Redemption Price for, and accrued and unpaid interest on, the Notes, without preference or priority of any kind, according to such amounts due and payable on all of the Notes; and 

THIRD: the balance, if any, to the Company or the applicable Guarantor, or to such other party as a court of competent jurisdiction directs.

 The Trustee may fix a record date and payment date for any payment to the Holders pursuant to this Section 6.10. If the Trustee so
fixes a record date and a payment date, at least 15 days prior to such record date, the Company will deliver to each Holder and the Trustee a written notice, which notice will state such record date, such payment date and the amount of such payment,
and if the Company is unable or refuses to do so, the Trustee will deliver such notice to each Holder. 
 Section 6.11 Undertaking for
Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the
suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and
good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 hereof or a suit by Holders of more than 10% in aggregate principal
amount of the then outstanding Notes.

 ARTICLE 7 

TRUSTEE 
 Section 7.01
Duties of Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee will exercise the rights and powers
vested in it by this Indenture, and use the same degree of care and skill in its exercise as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s own affairs. 

(b) Except during the continuance of an Event of Default: 

(i) the Trustee undertakes to perform such duties, and only such duties, as are specifically set forth in this Indenture, and no implied
covenants or obligations will be read into this Indenture against the Trustee; and 
 (ii) in the absence of bad faith on its part, the
Trustee may conclusively rely as to the truth of the statements and the correctness of the opinions expressed therein upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. 

(c) The Trustee may not be relieved from liabilities for its own negligent action, its own negligent failure to act, or its own willful
misconduct, except that: 
 (i) this paragraph does not limit the effect of Section 7.01(b) hereof; 

(ii) the Trustee will not be liable for any error of judgment made in good faith by a Responsible Officer unless it is proved that the Trustee
was negligent in ascertaining the pertinent facts; and 
 (iii) the Trustee will not be liable with respect to any action it takes or omits
to take in good faith in accordance with a direction received by it pursuant to Sections 6.05, 6.06, 13.02 or 13.03 hereof or any exercise in good faith of any trust or power conferred upon the Trustee under this Indenture with respect to the Notes.

 (d) Whether herein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to
Section 7.01(a), (b) and (c) hereof.

written notice at its Corporate Trust Office thereof from the Company or any Holder and such notice references the Notes and this Indenture or (ii) a Responsible Officer has actual knowledge thereof. 

Section 7.02 Rights of Trustee. 

(a) The Trustee may conclusively rely upon any written resolution, certificate, statement, instrument, opinion, report, notice, request,
direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter
stated in any written resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document. The Trustee may, however, in its
discretion make such further inquiry or investigation into such facts or matters as it may see fit and, if the Trustee determines to make such further inquiry or investigation, it will be entitled to examine the books, records and premises of the
Company or any Guarantor, personally or by agent or attorney and at the expense of the Company, and will incur no liability of any kind by reason of such inquiry or investigation.

Trustee will not be liable for any action it takes or omits to take in good faith in reliance on the Officers’ Certificate or Opinion of Counsel. 

(c) The Trustee may act through agents, attorneys or custodians and will not be responsible for the misconduct or negligence of any agent,
attorney or custodian appointed with due care.

negligence, the Trustee will not be liable for any action it takes or omits to take in good faith that it reasonably believes to be authorized or within the rights or powers conferred upon it by this Indenture.

matters relating to this Indenture and the Notes will be full and complete authorization and protection from liability in respect to any action taken, omitted or suffered by it hereunder in good faith and in accordance with and reliance upon the
advice or opinion of such counsel. 

  
 - 54 - 








 (f) The permissive rights of the Trustee to do things enumerated in this Indenture will not be
construed as a duty unless so specified herein. 
 (g) The Trustee will be under no obligation to exercise any of the rights or powers
vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and
liabilities that might be incurred by it in compliance with such request or direction. 
 (h) The rights, privileges, protections,
immunities and benefits given to the Trustee, including its right to be indemnified, are extended to, and will be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder,
including the Registrar, Paying Agent and Conversion Agent. 
 (i) The Trustee may request that the Company deliver an Officers’
Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may be signed by any Person authorized to sign an
Officers’ Certificate, including any Person specified as so authorized in any such certificate previously delivered and not superseded. 

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

(k) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder. 

Section 7.03 Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of
Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, if the Trustee acquires any conflicting interest it must eliminate the conflict within 90 days or
resign. Any Paying Agent, Registrar, Conversion Agent or co-registrar may do the same with like rights. However, the Trustee must comply with Section 7.09 hereof. 

Section 7.04 Trustee’s Disclaimer. The Trustee will not be responsible for and makes no representation as to the validity,
sufficiency, priority or adequacy of this Indenture or the Notes, it will not be accountable for the Company’s use of the proceeds from the Notes, and it will not be responsible for the recitals contained in this Indenture, which shall be
deemed statements of the Company, or for any other statement of the Company in this Indenture or in any document issued in connection with the sale of the Notes or in the Notes other than the Trustee’s certificate of authentication. 

Section 7.05 Notice of Defaults. If a Default occurs and is continuing and is actually known to a Responsible Officer, the Trustee
will send to each Holder notice of the Default within 90 days after such Default first occurs, or, if it is not known to the Trustee at such time, as soon as practicable after it is actually known to a Responsible Officer; provided,
however, that except in the case of a Default that is, or would lead to, an Event of Default described in 

  
 - 55 - 








 
6.01(a)(i), 6.01(a)(ii), Section 6.01(a)(iii) or Section 6.01(a)(iv) hereof, the Trustee may withhold the notice, and will be protected in so withholding, if and so long as it in good
faith determines that withholding the notice is in the interests of Holders. 
 Section 7.06 Compensation and Indemnity. 

(a) The Company will pay to the Trustee, from time to time, such compensation as will be agreed upon, from time to time, in writing for its
services. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Company will reimburse the Trustee upon request for all reasonable out-of-pocket fees and expenses incurred or made by it,
including costs of collection, in addition to the compensation for its services. Such expenses will include the reasonable compensation, fees and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts.
The Company will fully indemnify the Trustee (or any predecessor Trustee) against any and all loss, liability, claim, damage, fee or expense (including reasonable attorneys’ fees and expenses) incurred by it in connection with the acceptance
and administration of this trust and the performance of its duties hereunder, including the costs and expenses of defending itself against any claim (whether asserted by the Company, any Holder or any other Person) or liability in connection with
the exercise or performance of any of its powers or duties hereunder, or in connection with enforcing the provisions of this Section. The Trustee will notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee
to so notify the Company of any claim for which it may seek indemnity of which a Responsible Officer has actually received written notice will not relieve the Company of its obligations hereunder except to the extent such failure is adjudicated by a
court of competent jurisdiction to have materially prejudiced the Company. The Company will defend the claim and the Trustee will cooperate in the defense. If the Trustee is advised by counsel that it may have available to it defenses that are in
conflict with the defenses available to the Company, then the Trustee may have separate counsel, and the Company will pay the reasonable fees and expenses of such counsel. The Company will pay the reasonable fees and expenses of counsel to the
Trustee incurred in evaluating whether such defense and/or conflict exists. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own willful misconduct or
negligence. The Company need not pay for any settlement made by the Trustee without the Company’s consent, such consent not to be unreasonably withheld. All indemnifications and releases from liability granted hereunder to the Trustee will
extend to its officers, directors, employees, agents, attorneys, custodians, successors and assigns. 
 (b) To secure the Company’s
payment obligations under this Section 7.06, the Trustee will have a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by the Trustee, other than money or property held in trust to pay the
principal or Terminal Value of, the Change of Control Repurchase Price or Redemption Price, if any, for, and the accrued and unpaid interest, if any, on particular Notes. 

(c) The Company’s payment and indemnity obligations pursuant to this Section 7.06 will survive the resignation or removal of the
Trustee and the discharge of this Indenture. If the Trustee incurs expenses or renders services after the occurrence of a Default specified in Sections 6.01(a)(ix) or 6.01(a)(x) hereof, the expenses (including the reasonable fees and expenses of its
counsel) and the compensation for the services are intended to constitute expenses of administration under the Bankruptcy Law. 

  
 - 56 - 








 Section 7.07 Replacement of Trustee. 

(a) The Trustee may resign at any time by notifying the Company, in writing, at least 30 days prior to the proposed resignation. The Holders of
a majority in aggregate principal amount of then outstanding Notes may remove the Trustee by so notifying the Trustee, in writing. The Company may remove the Trustee if: 

(i) the Trustee fails to comply with Section 7.09 hereof; 

(ii) the Trustee is adjudged bankrupt or insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

 (iii) a receiver or other public officer takes charge of the Trustee or its property; or 

(iv) the Trustee otherwise becomes incapable of acting. 

(b) If the Trustee resigns, is removed by the Company or by the Holders of a majority in aggregate principal amount of the Notes then
outstanding, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company will promptly appoint a successor Trustee. 

(c) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will send a notice of its succession to Holders.
The retiring Trustee will, upon payment of all of its costs and the costs of its agents and counsel, promptly transfer all property held by it as Trustee to the successor Trustee, subject to the Lien provided for in Section 7.06 hereof. 

(d) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the
Company or the Holders of at least 10% of the aggregate principal amount of the Notes then outstanding may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee. 

(e) If the Trustee, after written request by any Holder, fails to comply with Section 7.09 hereof, such Holder may petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 (f) Notwithstanding the replacement of
the Trustee pursuant to this Section 7.07, the Company’s obligations under Section 7.06 hereof will continue for the benefit of the retiring Trustee. 

  
 - 57 - 








 Section 7.08 Successor Trustee by Merger. 

(a) If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets
to, another corporation or banking association, the resulting, surviving or transferee corporation or banking association without any further act will be the successor Trustee. 

(b) In case at the time such successor or successors by merger, conversion or consolidation to the Trustee succeeds to the trusts created by
this Indenture, any of the Notes have been authenticated, but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee, and deliver such Notes so authenticated; and, in case at that time
any of the Notes have not been authenticated, any such successor to the Trustee may authenticate such Notes, either in the name of any predecessor Trustee hereunder or in the name of the successor to the Trustee. 

Section 7.09 Eligibility; Disqualification. The Trustee will have (or, in the case of a corporation included in a bank holding
company system, the related bank holding company will have) a combined capital and surplus of at least $100,000,000, as set forth in its (or its related bank holding company’s) most recent published annual report of condition. 

Section 7.10 Trustee’s Application for Instructions from the Company. Any application by the Trustee for written instructions
from the Company 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 will be taken or such omission will be effective.
The Trustee will not be liable to the Company for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date will not be less than three
Business Days after the date any Officer actually receives such application, unless any such Officer has consented in writing to any earlier date), unless prior to taking any such action (or the effective date in the case of any omission), the
Trustee has received written instructions in response to such application specifying the action to be taken or omitted. 
 ARTICLE 8

 SATISFACTION AND DISCHARGE

Indenture.

least a majority of the aggregate principal amount of the Notes then outstanding (including consents obtained in connection with a repurchase of, or tender offer or exchange offer for, Notes), by Act of such Holders delivered to the Company and the
Trustee, the Company, when authorized by a Board Resolution, may amend or supplement this Indenture or the Notes or waive compliance with any provision of this Indenture or the Notes; provided, however, that, without the consent of

 It will not be necessary for
the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, but it will be sufficient if such consent approves the substance of such proposed amendment. 

Section 9.03 Execution of Supplemental Indentures. Upon the written request of the Company, the Trustee will sign any supplemental
indenture authorized pursuant to this Article 9 if the amendment contained therein does not affect the rights, duties, liabilities or immunities of the Trustee under this Indenture. If the supplemental indenture adversely affects the Trustee’s
rights, duties, liabilities or immunities under this Indenture, then the Trustee may, but need not, sign such supplemental indenture. In executing any such supplemental indenture, the Trustee will be provided with, and, subject to the provisions of
Section 7.01 hereof, will be fully protected in conclusively relying upon, an Officers’ Certificate and an Opinion of Counsel that 

  
 - 60 - 








 
comply with Sections 13.02 and 13.03 hereof and state that such supplemental indenture is (i) authorized and permitted under this Indenture and (ii) the legal, valid and binding
obligation of the Company enforceable against each of them in accordance with its terms. 
 Section 9.04 Notices of Amendment or
Supplemental Indentures. After an amendment or supplement to this Indenture or the Notes pursuant to Sections 9.01 or 9.02 hereof becomes effective, the Company will promptly deliver written notice to the Trustee, which notice will briefly
describe the substance of such amendment or supplement to this Indenture in reasonable detail and state the effective date of such amendment or supplement. The Company, or the Trustee, at the written direction of the Company, will then promptly
deliver a copy of such notice to each Holder. The failure to deliver such notice to each Holder, or any defect in such notice, will not impair or affect the validity of such amendment or supplement to this Indenture. 

Section 9.05 Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article 9: 

(a) this Indenture will be modified in accordance therewith; 

(b) such supplemental indenture will form a part of this Indenture for all purposes; and 

(c) every Holder will be bound thereby. 

Section 9.06 Revocation and Effect of Consents, Waivers and Actions. 

(a) Revocation. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the
Holder, and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder, or subsequent Holder, may revoke
the consent as to its Note or portion of a Note if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective. 

(b) Special Record Dates. The Company may, but is not obligated to, fix a record date for the purpose of determining the Holders
entitled to give their consent or take any other action described above or required, or permitted, to be taken pursuant to this Indenture. If a record date is fixed, then those Persons who were Holders at such record date (or their duly designated
proxies), and only those Persons, will be entitled to give such consent, to revoke any consent previously given or to take any such action, regardless of whether such Persons continue to be Holders after such record date. No such consent will be
valid or effective for more than 120 days after such record date. 
 (c) Binding Effect. After an amendment, supplement or waiver
becomes effective, it will bind every applicable Holder. Any amendment or supplement will become effective in accordance with the terms of the supplemental indenture relating thereto, which will become effective upon the execution thereof by the
Company and the Trustee. 
 Section 9.07 Notation on, or Exchange of, Notes. If any amendment, supplement or waiver changes the
terms of a Note, the Trustee may require the Holder of such Note to deliver 

  
 - 61 - 








 
such Note to the Trustee. The Trustee may place an appropriate notation on such Note about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so
determines, the Company, in exchange for the Note, will issue and the Trustee will authenticate a new Note that reflects the changed terms. 

ARTICLE 10 

SUBORDINATION 

Section 10.01 Agreement to Subordinate. The Company agrees, and each Holder by accepting a Note agrees, that the indebtedness
evidenced by the Notes is subordinated in right of payment, to the extent and in the manner provided in this Article 10, to the prior payment in full of all amounts due and payable in respect of all Senior Debt (whether outstanding on the date
hereof or hereafter created, incurred, assumed or guaranteed), and that the subordination is for the benefit of the holders of Senior Debt. 

Section 10.02 Liquidation; Dissolution; Bankruptcy. Upon any distribution to creditors of the Company in a liquidation or
dissolution of the Company, or in a bankruptcy, reorganization, insolvency, receivership, arrangement, adjustment, composition or similar proceeding relating to the Company, the Subsidiaries or their respective property, in an assignment for the
benefit of creditors or any marshaling of the Company’s assets and liabilities: 
 (a) holders of Senior Debt will be entitled to
receive payment in full of all principal, interest, penalties, fees, indemnifications, reimbursements, damages and other liabilities payable under the documentation governing any indebtedness due in respect of such Senior Debt (including interest
after the commencement of any bankruptcy proceeding at the rate specified in the applicable Senior Debt), or provision shall be made for such payment in cash or cash equivalents or otherwise in a manner satisfactory to the holders of such Senior
Debt, before the Holders will be entitled to receive any payment or distribution of any kind, whether in cash, property or securities with respect to the Notes; and 

(b) until all principal, interest, penalties, fees, indemnifications, reimbursements, damages and other liabilities payable under the
documentation governing any indebtedness due with respect to Senior Debt (as provided in clause (i) above) are paid in full, any payment or distribution to which Holders would be entitled but for this Article 10 will be made to holders of
Senior Debt, as their interests may appear. 
 Section 10.03 Default on Designated Senior Debt. 

(a) The Company may not make any payment or distribution to the Trustee or any Holder in respect of principal, interest, penalties, fees,
indemnifications, reimbursements, damages and other liabilities payable under the documentation governing any indebtedness due with respect to the Notes and may not acquire from the Trustee or any Holder any Notes for cash or property until all
principal and other principal, interest, penalties, fees, indemnifications, reimbursements, damages and other liabilities payable under the documentation governing any indebtedness due with respect to the Senior Debt have been paid in full if: 

(i) a payment default on any Designated Senior Debt occurs and is continuing; or 

  
 - 62 - 








 (ii) any other default occurs and is continuing on any series of Designated Senior Debt that
permits holders of that series of Designated Senior Debt to accelerate its maturity and the Trustee receives a written notice of such default (a “Payment Blockage Notice”) from the Company or the holders of any Designated Senior
Debt. If the Trustee receives any such Payment Blockage Notice, no subsequent Payment Blockage Notice will be effective for purposes of this Section 10.03 unless and until (A) at least 360 days have elapsed since the delivery of the
immediately prior Payment Blockage Notice and (B) all scheduled payments of any principal or Terminal Value of, Change of Control Repurchase Price or Redemption Price for, interest on the Notes that have come due have been paid in full in cash.

 No nonpayment default that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Trustee may be, or may
be made, the basis for a subsequent Payment Blockage Notice unless such default has been cured or waived for a period of not less than 90 days. 

(b) The Company may and will resume payments on and distributions in respect of the Notes and may acquire them upon the earlier of: 

(i) in the case of a payment default, upon the date upon which such default is cured or waived, and 

(ii) in the case of a nonpayment default, upon the earlier of the date on which such nonpayment default is cured or waived and 179 days after
the date on which the applicable Payment Blockage Notice is received, unless the maturity of any Designated Senior Debt has been accelerated, 
 if this
Article 10 otherwise permits such payment, distribution or acquisition at the time of such payment, distribution or acquisition. 

Section 10.04 Acceleration of Notes. If payment of the Notes is accelerated because of an Event of Default, the Company will
promptly notify holders of Senior Debt of the acceleration. 
 Section 10.05 When Distribution Must Be Paid Over. In the event
that the Trustee or any Holder of the Notes receives any payment of any obligations with respect to the Notes at a time when the payment is prohibited by Section 10.03 hereof and a Responsible Officer or the Holder, as applicable, has actual
knowledge that the payment is prohibited by Section 10.03 hereof, such payment will be held by the Trustee or such Holder, in trust for the benefit of, and will be paid forthwith over and delivered, upon written request, to, the holders of
Senior Debt as their interests may appear, their Representative under the agreement, indenture or other document (if any) pursuant to which Senior Debt may have been issued, as their respective interests may appear, the trustee in bankruptcy,
receiver, liquidating trustee or custodian for application to the payment of all obligations with respect to Senior Debt remaining unpaid to the extent necessary to pay such obligations in full in accordance with their terms, after giving effect to
any concurrent payment or distribution to or for the holders of Senior Debt. 

  
 - 63 - 








 With respect to the holders of Senior Debt, the Trustee undertakes to perform or to observe only
those obligations or covenants on the part of the Trustee as are specifically set forth in this Article 10, and no implied covenants or obligations with respect to the holders of Senior Debt will be read into this Indenture against the Trustee. The
Trustee will not be deemed to owe any fiduciary duty to the holders of Senior Debt, and will not be liable to any such holders if the Trustee pays over or distributes to or on behalf of Holders or the Company or any other Person money or assets to
which any holders of Senior Debt are then entitled by virtue of this Article 10, except if such payment is made as a result of the willful misconduct or gross negligence of the Trustee. 

Section 10.06 Notice by the Company. The Company will promptly notify the Trustee and the Paying Agent in writing of any facts
known to the Company that would cause a payment of any obligations with respect to the Notes to violate this Article 10 or would prohibit the making of any payment to or by the Trustee in respect of the Notes, but failure to give such notice will
not affect the subordination of the Notes to the Senior Debt as provided in this Article 10. 
 Section 10.07 Subrogation. Until
the Notes are paid in full, Holders will be subrogated (equally and ratably with all other indebtedness pari passu with the Notes) to the rights of holders of Senior Debt to receive distributions applicable to Senior Debt to the extent that
distributions otherwise payable to the Holders have been applied to the payment of Senior Debt. A distribution made under this Article 10 to holders of Senior Debt that otherwise would have been made to Holders is not, as between the Company and
Holders, a payment by the Company on the Notes. 
 Section 10.08 Relative Rights. This Article 10 defines the relative rights of
Holders and holders of Senior Debt. Nothing in this Indenture will: 
 (i) impair, as between the Company and Holders, the obligations of
the Company, which are absolute and unconditional, to pay any principal or Terminal Value of, Change of Control Repurchase Price or Redemption Price for, and interest on, the Notes in accordance with their terms; 

(ii) affect the relative rights of Holders and creditors of the Company other than their rights in relation to holders of Senior Debt; 

(iii) prevent the Trustee or any Holder from exercising its available remedies upon a Default or Event of Default, subject to the rights of
holders and owners of Senior Debt to receive distributions and payments otherwise payable to Holders; or 
 (iv) prevent the conversion of
the Notes into Conversion Shares pursuant to, and in accordance with, the provisions of Article 11. 
 If the Company fails because of this
Article 10 to pay any principal or Terminal Value of, Change of Control Repurchase Price or Redemption Price for, and interest on, the Notes on the due date, the failure is still a Default or Event of Default. 

Section 10.09 Subordination May Not Be Impaired. No right of any present or future 

  
 - 64 - 








 
holder of Senior Debt to enforce the subordination of the indebtedness evidenced by the Notes may be impaired by any act or failure to act by the Company, any such holder or any Holder or by the
failure of the Company or any Holder to comply with this Indenture, regardless of any knowledge thereof that any such holder may have or be otherwise charged with. 

Section 10.10 Distribution or Notice to Representative. Whenever a distribution is to be made or a notice given to holders of
Senior Debt, the distribution may be made and the notice given to such holders’ Representative. 
 Section 10.11 Reliance on
Judicial Order or Certificate. Upon any payment or distribution of assets of the Company referred to in this Article 10, the Trustee and the Holders will be entitled to conclusively rely upon any order or decree made by any court of competent
jurisdiction or upon any certificate of such Representative or of the liquidating trustee or agent or other Person making any distribution to the Trustee or to the Holders for the purpose of ascertaining the Persons entitled to participate in such
distribution, the holders of the Senior Debt and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 10. 

Section 10.12 Rights of Trustee and Paying Agent. Notwithstanding the provisions of this Article 10 or any other provision of this
Indenture, the Trustee will not be charged with knowledge of the existence of any facts that would prohibit the making of any payment or distribution by the Trustee, and the Trustee and the Paying Agent may continue to make payments on the Notes,
unless a Responsible Officer of the Trustee has received at its Corporate Trust Office at least five Business Days prior to the date of such payment written notice of facts that would cause the payment of any obligations with respect to the Notes to
violate this Article 10 and prior to the receipt of any such written notice, the Trustee shall be entitled in all respects to assume that no such facts exist; provided, however, that if a Responsible Officer of the Trustee shall not
have received, at least three Business Days prior to the date upon which by the terms hereof any such money may become payable for any purpose (including, without limitation, the payment of the principal amount, issue price, Redemption Price,
purchase price, Change in Control Purchase Price or interest, if any and in each case to the extent applicable, as the case may be, in respect of the Notes), the notice with respect to such money provided for in this Article 10, then, anything
herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such money and to apply the same to the purpose for which such money was received and shall not be affected by any notice to the contrary
which may be received by it within three Business Days prior to such date. Only the Company or a Representative may give the notice. Nothing in this Article 10 will impair the claims of, or payments to, the Trustee under or pursuant to
Section 7.06 hereof. 
 Subject to the provisions of Section 7.01, the Trustee shall be entitled to conclusively rely on the
delivery to it of a written notice by a Representative to establish that a notice has been given by a holder of Senior Debt (or a trustee or agent on behalf of any such holder). In the event that the Trustee determines in good faith that further
evidence is required with respect to the right of Representative to participate in any payment or distribution pursuant to this Article 10, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to
the amount of Senior Debt held by the Representative, the extent to which the Representative is entitled to participate in such payment or distribution and any other facts 

  
 - 65 - 








 
pertinent to the rights of such Person under this Article 10, and if such evidence is not furnished, the Trustee may defer any payment which it may be required to make for the benefit of the
Representative pursuant to the terms of this Indenture pending judicial determination as to the rights of such Person to receive such payment. 

The Trustee in its individual or any other capacity may hold Senior Debt with the same rights as set forth in this Article 10 as it would have
if it were not Trustee. Any agent of the Trustee may do the same with like rights. 
 Section 10.13 Authorization to Effect
Subordination. Each Holder, by the Holder’s acceptance of a Note, authorizes and directs the Trustee on such Holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this
Article 10, and appoints the Trustee to act as such Holder’s attorney-in-fact for any and all such purposes. If the Trustee does not file a proper proof of claim or proof of debt in the form required in any proceeding referred to in
Section 6.09 hereof at least 30 days before the expiration of the time to file such claim, the Representatives are hereby authorized to file an appropriate claim for and on behalf of the Holders. 

Section 10.14 Amendments. The provisions of this Article 10 may not be amended or modified without the written consent of the
holders of all Senior Debt. In addition, any amendment to, or waiver of, the provisions of this Article 10 that adversely affects the rights of the Holders will require the consent of the Holders of at least 75% in aggregate principal amount of
Notes then outstanding. 
 ARTICLE 11 

CONVERSION 

Section 11.01 Right To Convert Upon a Qualified PO. 

(a) General. Each Holder will have the option to elect to convert all or a portion of its Notes, having a
principal amount equal to $1,000 or an integral multiple of $1,000 in excess thereof, into shares of Common Stock (“Conversion Shares”) at any time during the period beginning on the Business Day immediately following a Qualified PO
Filing Date and ending on a date no less than 30 Business Days thereafter that is set by the Company by notice to the Holders (such date, the “Conversion Deadline”). The Company will provide the Holders, the Trustee and the
Conversion Agent (if other than the Trustee) with written notice of the Qualified PO Filing Date and issue a press release announcing the same no later than the Business Day immediately following the Qualified PO Filing Date. Such notice will
include the applicable Conversion Deadline. 
 Section 11.02 Conversion Procedures. 

(a) General. To exercise its conversion right with respect to a beneficial interest in a Global Note, the owner of such beneficial
interest must (i) comply with the Applicable Procedures for converting such beneficial interest; and (ii) pay any taxes or duties that such Holder is required to pay under the proviso to Section 11.02(d) hereof. 

  
 - 66 - 








 To exercise its conversion right with respect to a Certificated Note, the Holder of such
Note must (i) complete and manually sign the conversion notice on the back of the Note, or a facsimile of such conversion notice (such notice, or such facsimile, the “Conversion Notice”); (ii) deliver such signed and
completed Conversion Notice and such Note to the Conversion Agent at its office; (iii) furnish any endorsements and transfer documents that the Company, Conversion Agent, Trustee or Transfer Agent may require; and (iv) pay any transfer
taxes or similar duties that such Holder is required to pay under the proviso to Section 11.02(d) hereof. 
 For each
Note with regard to which a Holder satisfies the foregoing requirements and which conversion of such Note is not otherwise prohibited under this Indenture, the closing date of the Qualified PO will be the “Conversion Date” for such
Note. 
 The conversion of any Note will be deemed to occur at the Open of Business on the Conversion Date for such Note, and any
converted Note or portion thereof will cease to be outstanding upon conversion. 
 (b) Termination of Election of Conversion.
Any Conversion Notice shall be irrevocable, subject only to the closing of a Qualified PO no later than one year from the applicable Qualified PO Filing Date or an earlier determination by the Company that it no longer intends to consummate such
Qualified PO. The Conversion Notice will be void in the event:  
 (i) such Qualified PO is not closed within one year from the
applicable Qualified PO Filing Date; or 
 (ii) the Company provides notice to Holders and the Conversion Agent that it no longer intends to
consummate such Qualified PO. 
 The Company will provide the Holders and the Conversion Agent the notice referred to in the foregoing
clause (ii) promptly after it makes the determination not to consummate the Qualified PO, but, for the avoidance of doubt, such determination will be in the Company’s sole discretion. 

(c) Conversions in Part. If a Holder surrenders only a portion of the principal amount of a Certificated Note for conversion,
promptly after the Conversion Date, the Company will, in accordance with Section 2.05 hereof, execute and deliver to the Trustee, and the Trustee will, upon receipt of a Company Order and the documents required by Sections 13.02 and 13.03
hereof, in accordance with Section 2.05 hereof, authenticate and deliver to such Holder a new Certificated Note in an authorized denomination, having a principal amount equal to the aggregate principal amount of the unconverted portion of the
Certificated Note surrendered for conversion and bearing registration numbers not contemporaneously outstanding and any restrictive legends that such Certificated Note must bear under Section 2.10 hereof. 

Upon the conversion of any beneficial interest in a Global Note, the Conversion Agent will promptly request that the Trustee make a notation
on the “Schedule of Increases and Decreases of Global Note” of such Global Note to reduce the principal amount represented by such Global Note by the principal amount of the converted beneficial interest. If all of the beneficial interests
in a Global Note are so converted, such Global Note will be deemed surrendered to the Trustee for cancellation, and the Trustee will cause such Global Note to be cancelled in accordance with the Applicable Procedures and the Trustee’s internal
procedures. 

  
 - 67 - 








 (d) Taxes and Duties. If a Holder converts a Note, the Company will pay any
documentary, stamp or similar issue or transfer tax due on the issue of any shares of the Common Stock upon the conversion; provided, however, that if any such tax is due because the converting Holder requested that shares of Common
Stock be issued in a name other than its own, such Holder will pay such tax. Such Common Stock shall not be issued or delivered unless all such taxes, if any, payable by the Holder have been paid. 

(e) Notices. The Conversion Agent will, as promptly as possible following the Conversion Date, and in no event later than the
Business Day immediately following the Conversion Date, deliver to the Company and the Trustee notice that the Conversion Date has occurred, which notice will state the Conversion Date, the principal amount of Notes converted on the Conversion Date
and the names of the Holders that converted Notes on the Conversion Date. 
 The Company will provide each Holder that elects
to convert all or a portion of its Notes into Conversion Shares with written notice of the effective date of the registration statement filed under the Securities Act in connection with the applicable Qualified PO no later than the Business Day
immediately following the effective date. The notice will include the expiration date of the period beginning on the Conversion Deadline and ending on the day that is 180 days after the pricing date of the Qualified PO (the “Lock-up
Period”). 
 (f) Notes subject to a Conversion Notice. Notwithstanding anything to the contrary contained
herein, once a Conversion Notice has been signed and delivered in accordance with Section 11.02(a), each Note subject to such Conversion Notice may not be transferred or sold by the Holder thereof (other than as required in order to consummate
the conversion of such Note in accordance with this Article 11) unless and until the Company provides notice to Holders and the Conversion Agent that it no longer intends to consummate such Qualified PO in accordance with Section 11.02(b)(ii).

 Section 11.03 Settlement Upon Conversion. 

(a) Conversion Obligation. 

(i) Calculation of Conversion Shares. Upon conversion, a Holder will receive such Holder’s Pro Rata Portion of a number of
Conversion Shares equal to the greater of: 
  

	 	(A)	the Qualified PO Principal Amount divided by the Applicable Conversion Price. The “Applicable Conversion Price” will be the public offering price per share of Common Stock in the Qualified PO multiplied
by the applicable percentage of public offering price set forth in the table below determined as of the pricing date of the Qualified PO. 


  
 - 68 - 









					
	 Pricing Date of Qualified PO
	  	Percentage of Public
Offering Price	 
	 On or before December 31, 2014
	  	 	90	% 
	 January 1, 2015 to June 30, 2015
	  	 	86	% 
	 July 1, 2015 to December 31, 2015
	  	 	78	% 
	 January 1, 2016 to June 30, 2016
	  	 	73	% 
	 July 1, 2016 to December 31, 2016
	  	 	68	% 
	 January 1, 2017 to June 30, 2017
	  	 	63	% 
	 July 1, 2017 to December 31, 2017
	  	 	58	% 
	 January 1, 2018 to June 30, 2018
	  	 	53	% 
	 July 1, 2018 to December 31, 2018
	  	 	48	% 
	 On or after January 1, 2019
	  	 	45	% 

 and 
  

	 	(B)	the difference between (A) the Pre-Qualified PO Share Number divided by one minus a fraction, the numerator of which is the Qualified PO Principal Amount and the denominator of which is the Upside Trigger and
(B) the Pre-Qualified PO Share Number. 

 (ii) Delivery of Conversion Shares. The Company will not issue any
fractional shares of Common Stock upon conversion of the Notes and the number of Conversion Shares will be rounded up or down to the nearest whole number of shares. The Company will pay in cash accrued and unpaid interest on the Notes to, but not
including, the closing date of the Qualified PO. The Conversion Shares and accrued and unpaid interest will be delivered or paid, as applicable, to the Holder thereof on the closing date of the Qualified PO. Holders will become the record holders of
the Conversion Shares so delivered as of the Open of Business on such closing date. 
 (b) Conversion of Multiple Notes by a Single
Holder. If a Holder converts more than one Note on a single Conversion Date, the Conversion Shares due in respect of such conversion will be computed based on the total principal amount of Notes converted on such Conversion Date by such Holder.

 Section 11.04 Common Stock Issued Upon Conversion. 

(a) Prior to issuing of any shares of Common Stock under this Article 11, and from time to time thereafter as may be necessary, the Company
will reserve out of its authorized but unissued shares of Common Stock a number of shares of Common Stock sufficient to permit the conversion of all Notes with respect to which conversion rights have been exercised in accordance with
Section 11.02. 
 (b) Any shares of Common Stock delivered upon the conversion of the Notes will be newly issued shares or treasury
shares, duly and validly issued, fully paid, nonassessable, free from preemptive rights and free of any lien or adverse claim (except to the extent of any lien or adverse claim created by the action or inaction of the Holder or other Person to whom
such shares of Common Stock will be delivered). In addition, the Company will endeavor to comply promptly with all federal and state securities laws regulating the offer and delivery of any shares of Common Stock issuable upon conversion of the
Notes. Other than as set forth in the Registration Rights Agreement, the Company will not be obligated to register the offer and sale of such Common Stock under the Securities Act or any other applicable securities laws. 

  
 - 69 - 








 (c) If any shares of the Common Stock issued upon conversion will, upon delivery as part of the
conversion obligation, be “restricted securities” (within the meaning of Rule 144 or any successor provision in effect at such time), such shares of Common Stock (i) will be issued in physical, certificated form; (ii) will not be
held in book-entry form through the facilities of the Depositary; and (iii) will bear any restrictive legends the Company or the Transfer Agent deem necessary to comply with applicable law. 

Section 11.05 Adjustment of Upside Trigger. 

(a) If at any time or from time to time after the date hereof and before the closing of a Qualified PO, the Company shall sell (an
“Equity Sale”) to any Person the Company’s Capital Stock or any securities convertible into or exchangeable for the Company’s Capital Stock, whether or not the rights to exchange or convert thereunder are immediately
exercisable (“Convertible Securities”), then if the Closing Date Equity Value is greater than the Upside Trigger, the Upside Trigger will be increased based on the following formula: 

 
 



 
 where 
  

			
		
	 VT1 =
	  	the Upside Trigger in effect immediately after the closing of the Equity Sale.
		
	 VT0 =
	  	the Upside Trigger in effect immediately prior to the closing of the Equity Sale.
		
	 GP  =
	  	the gross proceeds to the issuer from the Equity Sale.
		
	 EV  =
	  	the Closing Date Equity Value.

 (b) Successive Adjustments. After an adjustment to the Upside Trigger under this Article 11, any
subsequent event requiring an adjustment under this Article 11 will cause an adjustment to the Upside Trigger as so adjusted, without duplication. 

(c) Restrictions on Adjustments. Notwithstanding the foregoing, no adjustment to the Upside Trigger will be made pursuant to
this Section 11.05(a) if the Upside Trigger would be increased by less than $2,000,000 as a result of the adjustment. 
 In
addition, notwithstanding anything to the contrary elsewhere in this Indenture, the Upside Trigger will not be adjusted as a result of the issuance of any of the following: 

(i) Capital Stock upon the conversion of any Convertible Securities outstanding on the Issue Date; 

  
 - 70 - 








 (ii) Capital Stock or Convertible Securities issued or issuable by reason of a dividend, stock
split, split-up or other distribution on Capital Stock and Capital Stock issued or deemed issued as a dividend or distribution on Capital Stock; 

(iii) Capital Stock and/or options, warrants or rights to purchase Capital Stock and the Capital Stock issued pursuant to such options,
warrants or other rights to employees, consultants, officers or directors pursuant to any stock plans, equity incentive plans, restricted stock plans or other similar arrangements; 

(iv) Capital Stock or Convertible Securities to lenders, financial institutions, equipment lessors, landlords, brokers or similar entities in
connection with commercial credit arrangements, equipment financings, commercial property lease transactions or similar transactions; 
 (v)
Capital Stock or Convertible Securities to suppliers or third party service providers in connection with the provision of goods or services; or 

(vi) Capital Stock or Convertible Securities in connection with any settlement of any action, suit, proceeding or litigation. 

(d) Notices. Upon the occurrence of each adjustment or other determination of the Upside Trigger pursuant to this Section 11.05,
the Company will promptly as reasonably practicable compute such adjustment and the Company will (a) furnish to the Trustee, the Paying Agent, the Conversion Agent and each of the Holders an Officers’ Certificate setting forth such
adjustment and showing in reasonable detail the facts upon which such adjustment or other determination is based, which Officers’ Certificate each of the Trustee, the Paying Agent and the Conversion Agent may treat as conclusive evidence that
the adjustment specified in such Officers’ Certificate is correct and will be in effect as of the effective time specified in such Officers’ Certificate and (b) furnish, upon written notice at any time of any Holder to such Holder a
written notice, which notice will include (i) any and all adjustments or other determinations made to the Upside Trigger since the date of this Indenture and (ii) the Upside Trigger at that time in effect. The failure to deliver such
notice will not affect the legality or validity of any such adjustment. 
 Section 11.06 No Responsibility of Trustee, Conversion
Agent and Paying Agent. The Trustee, Conversion Agent and the Paying Agent will not have any duty or responsibility to calculate the Equity Value or the Upside Trigger or determine whether any facts exist that require an adjustment of the Upside
Trigger, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed in making the same. None of the Trustee, the Paying Agent or the Conversion Agent will be responsible for any
failure of the Company to deliver the Conversion Shares due 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 11.

 ARTICLE 12 

REDEMPTION AT THE OPTION OF THE COMPANY 

Section 12.01 No Sinking Fund; Notes Not Redeemable Prior to Qualified PO or Change of Control. No sinking fund is provided for
the Notes. Prior to the earlier of the closing of a Qualified PO and a Change of Control Repurchase Date, the Company may not redeem the Notes. 

Section 12.02 Right to Redeem in Connection with a Qualified PO. Prior to the Maturity Date, if the closing of a Qualified PO
occurs, the Company has the option to redeem (a “Qualified PO Redemption Right”) all, but not less than all, of the Notes (a “Qualified PO Redemption”) that are not subject to a Conversion Notice on the Redemption
Date for an amount of cash equal to the Redemption Price for such Redemption Date. 
 The Company shall give notice of its intention to
exercise of the Qualified PO Redemption Right (a “Qualified PO Redemption Notice”) to the Holders during the period beginning on the Business Day following the Conversion Deadline and ending on the tenth Business Day thereafter. Any
Qualified PO Redemption Notice shall be irrevocable, subject only to the closing of a Qualified PO no later than one year from the applicable Qualified PO Filing Date or an earlier determination that the Company no longer intends to consummate such
Qualified PO. In the event (i) the Qualified PO giving rise to the Qualified PO Redemption Right is not closed within one year from the applicable Qualified PO Filing Date or (ii) the Company provides notice to Holders that it no longer
intends to consummate such Qualified PO (a “Qualified PO Revocation Notice”), the Qualified PO Redemption Notice will be void. The Company will provide Holders a Qualified PO Revocation Notice promptly after the Company makes the
determination, in the Company’s sole discretion, not to consummate the Qualified PO. 
 Section 12.03 Right to Redeem Following
a Change of Control . On or following a Change of Control Repurchase Date, in the event that any Notes remain outstanding following such Change of Control Repurchase Date, the Company may redeem (a “Change of Control
Redemption”) any such Notes that remain outstanding in whole but not in part, at any time at the Redemption Price for such Redemption Date. Any Change of Control Redemption and any related Redemption Notice may, in the Company’s
discretion, be subject to the satisfaction or one or more conditions precedent. 
 Section 12.04 General. Redemption
Notice. At least 30 calendar days but not more than 60 calendar days prior to any Redemption Date and, in the case of a Qualified PO Redemption, on a date following the closing date of the Qualified PO, the Company (with written notice to the
Trustee, in the case of a Global Note, no less than one Business Day (or such shorter period as agreed by the Trustee), or, in the case of a Certificated Note, no less than 10 calendar days (or such shorter period as agreed by the Trustee) prior to
the sending of such redemption notice in the event the Trustee is engaged by the Company to send such notice or cause such notice to be sent in the Company’s name and at the Company’s expense), in order to effect a Qualified PO Redemption
or a Change of Control Redemption, will send to each Holder (and to any beneficial owner of a Global Note, as required by applicable law) a written notice of redemption (the “Redemption Notice,” and the date of such sending, the
“Redemption Notice Date”) and, substantially contemporaneously therewith, the Company will issue a press release announcing such redemption. 

  
 - 72 - 








 For any redemption, the Redemption Notice corresponding to such redemption will specify: 

(i) a brief description of the Company’s redemption right under this Indenture; 

(ii) the date specified for such redemption (the “Redemption Date”), which date must be a Business Day; provided that,
for a Qualified PO Redemption, the Redemption Date must be not less than 30 calendar days, nor more than 60 calendar days, immediately following the date on which the closing of the Qualified PO occurs; 

(iii) the redemption price for the Notes to be redeemed on such Redemption Date, which will be a price equal to 100% of the principal amount
of the Notes to be redeemed, plus accrued and unpaid interest, if any, on such Notes to, but excluding, such Redemption Date (the “Redemption Price”); provided, however, that if a Redemption Date occurs after a Regular
Record Date, but on or prior to the Interest Payment Date corresponding to such Regular Record Date, the Redemption Price for any Notes to be redeemed will equal 100% of the principal amount of such Notes, and accrued and unpaid interest, if any, on
such Notes to, but excluding, such Redemption Date will be payable, on such Interest Payment Date, to the Holder of such Notes at the Close of Business on such Regular Record Date, and the Redemption Price shall not include such accrued and unpaid
interest; 
 (iv) the name and address of the Paying Agent; 

(v) that Notes must be surrendered to the Paying Agent on or before the Redemption Date to collect the Redemption Price; 

(vi) that, unless the Company defaults in paying the Redemption Price on the Redemption Date, interest, if any, on a Note will cease to accrue
on and after the Redemption Date; 
 (vii) the CUSIP and ISIN number(s) of the Notes; 

(viii) that no representation is made as to the correctness or accuracy of the CUSIP and ISIN number(s), if any, listed in such notice or
printed on the Notes; and 
 (ix) any conditions precedent applicable to the redemption. 

The Company may provide in any Redemption Notice that payment of the Redemption Price and the performance of the Company’s obligations
with respect to such redemption may be performed by another Person.

 Section 12.05 Effect of Redemption Notice. After the Company has delivered a
Redemption Notice, each Holder will have the right to receive payment of the Redemption Price for its Notes on the later of (i) the Redemption Date and (ii) (a) if the Notes are Certificated Notes, delivery of its Notes to the Paying
Agent or (b) if the Notes are Global Notes, compliance with the Applicable Procedures relating to the redemption and delivery of the beneficial interests to be redeemed to the Paying Agent. 

Section 12.06 Deposit of Redemption Price. Prior to 10:00 a.m., New York City time, on the Redemption Date, the Company will
deposit with the Paying Agent (or, if the Company or any of the Subsidiaries is acting as the Paying Agent, will segregate and hold in trust as provided in Section 2.07 hereof) an amount of immediately available funds sufficient to pay the
Redemption Price of all of the then-outstanding Notes. 
 Section 12.07 Effect of Deposit. If, as of 10:00 a.m., New York City
time, on any Redemption Date, the Company, in accordance with Section 12.06 hereof, has deposited with the Paying Agent money sufficient to pay the Redemption Price for every Note validly delivered in accordance with Section 12.05 hereof,
then, at the Close of Business on such Redemption Date: 
 (A) every Note outstanding immediately prior to the Close of
Business on such Redemption Date will cease to be outstanding and interest, if any, on such Notes will cease to accrue (regardless of whether such Notes were delivered to the Paying Agent or book-entry transfer has been made, as applicable), except
to the extent provided in the proviso to Section 12.04(a)(iii) hereof; and 
 (B) all other rights of the Holders of
such Notes with respect to such Notes (other than the right to receive payment of the Redemption Price and other than as provided in the proviso to Section 12.04(a)(iii) hereof) will terminate. 

Section 12.08 Covenant Not to Redeem Notes Upon Certain Events of Default. 

(a) General. Notwithstanding anything to the contrary in this Article 12, the Company will not redeem any Notes under this Article 12
if the principal amount of the Notes has been accelerated and such acceleration has not been rescinded on, or prior to, the Redemption Date (except in the case of an acceleration resulting from a default by the Company that would be cured by the
Company’s payment of the Redemption Price for such Notes). 
 (b) Return of Notes. If a Holder delivers a Note for redemption
pursuant to Section 12.05 hereof and, on the Redemption Date, pursuant to this Section 12.08, the Company is not permitted to redeem such Note, the Paying Agent will (i) if such Note is a Certificated Note, return such Note to such
Holder, and (ii) if such Note is held in book-entry form, in compliance with the Applicable Procedures, deem to be cancelled any instructions for book-entry transfer of such Note. 

Section 12.09 Repayment to the Company. Subject to any applicable property laws, if, six months after the Redemption Date, any
cash held by the Paying Agent remains unclaimed, 

  
 - 74 - 








 
the Paying Agent will promptly return such cash to the Company; provided, however, that, to the extent that the aggregate amount of cash deposited by the Company pursuant to
Section 12.06 exceeds the aggregate Redemption Price of every Note outstanding, then as soon as practicable following the Redemption Date, the Trustee will return such excess to the Company.

 [FORM OF REVERSE OF NOTE] 

Energy & Exploration Partners, Inc. 

8.00% Convertible Subordinated Notes due 2019 

This Note is one of a duly authorized issue of notes of Energy & Exploration Partners, Inc., a Delaware corporation (the
“Company”), designated as its 8.00% Convertible Subordinated Notes due 2019 (the “Notes”), all issued or to be issued under and pursuant to an indenture dated as of July 22, 2014 (the
“Indenture”), among the Company and U.S. Bank National Association (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of
rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders. Capitalized terms used herein and not defined herein have the meanings ascribed to them in the Indenture, and the terms of the Notes include those
stated in the Indenture and those incorporated into the Indenture. Notwithstanding anything herein to the contrary, to the extent that any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture
will govern and control. 
 This Note will initially accrue interest at a rate equal to 8.00% per annum; provided that the
Interest Rate on this Note will increase by 0.50% per annum on the Interest Payment Date falling on July 1, 2015 and on each Interest Payment Date thereafter in accordance with the provisions of the Indenture. Interest accruing on this
Note will be payable entirely in cash. 
 If an Event of Default, as defined in the Indenture, shall have occurred and be continuing (other
than an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company), the Terminal Value of all Notes may be declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes
then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture. In case of certain events of bankruptcy, insolvency or
reorganization of the Company as described above, the Terminal Value of the Notes will automatically become immediately due and payable. 

Subject to the terms and conditions of the Indenture, the Company will make or cause to be made all payments and deliveries in respect of any
principal or Terminal Value of, Change of Control Repurchase Price or Redemption Price for, and accrued but unpaid interest on, as the case may be, to the Holder who surrenders this Note to a Paying Agent to collect such payments in respect of this
Note. The Company will pay or cause to be paid all amounts in cash or by wire transfer of immediately available funds on the relevant payment date. 

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

  
 A-6 








 Payment of principal, interest, penalties, fees, indemnifications, reimbursements, damages and
other liabilities payable under the documentation governing any indebtedness due with respect to this Note is subordinated to the prior payment of Senior Debt on the terms provided in the Indenture. 

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligations of the Company,
which are absolute and unconditional, to pay any principal or Terminal Value of, Change of Control Repurchase Price or Redemption Price for, and interest on, this Note at the place, at the respective times, at the rate and in the lawful money herein
prescribed. 
 The Notes are issuable in registered form without coupons in minimum denominations of $1,000.00 of principal amount and in
integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay
any taxes and fees required by law or permitted by the Indenture. The Registrar need not transfer or exchange any Notes in respect of which a Change of Control Repurchase Notice has been given and not withdrawn after the Company has delivered a
Redemption Notice (except to the extent that Notes are converted or the Company fails to pay the Redemption Price in accordance with the terms of the Indenture) or in respect of which a Conversion Notice has been given (except, in the case of a Note
to be converted in part, the portion of the Note not to be converted). 
 No sinking fund is provided for the Notes. Subject to the terms
and conditions of the Indenture, the Company may redeem all, but not less than all, of the Notes that are not subject to a Conversion Notice if the closing of a Qualified PO occurs. Additionally, on or following a Change of Control Repurchase Date,
in the event that any Notes remain outstanding, the Company may redeem any such Notes, in whole but not in part. Any redemption will be at the Redemption Price and subject to the notice provisions set forth in the Indenture. 

Subject to the terms and conditions of the Indenture, upon the occurrence of a Change of Control, the Holder of this Note will have the right,
at its option, to require the Company to repurchase for cash this Note at the applicable Change of Control Repurchase Price set forth in the Indenture. 

Subject to, and upon compliance with, the terms and conditions of the Indenture, the Holder of this Note may, at its option, convert all of
this Note, or any portion of this Note, into Conversion Shares upon the closing of a Qualified PO. 
 In addition to the rights provided to
Holders under the Indenture, Holders shall have all the rights set forth in the Registration Rights Agreement, dated as of July 22, 2014, among the Company and Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC and Global Hunter
Securities, LLC/Sea Port Group Securities, LLC. 
 Initially, U.S. Bank National Association will act as the Trustee, Paying Agent,
Conversion Agent and Registrar. The Company may appoint and change any Paying Agent, Conversion Agent or Registrar; provided, that the Company will maintain at least one Paying Agent, Conversion Agent and Registrar in the continental United
States. The Company or any of the Subsidiaries may act as Paying Agent, Conversion Agent or Registrar.
