 Exhibit 10.4 
 AMENDMENT No. 1 To Plan Convertible Promissory Note 
 This
Amendment No. 1 to Plan Convertible Promissory Note dated November 17, 2010 (hereinafter, the “Note”) effective as of June 6, 2012 (“Effective Date”) by and between Accentia Biopharmaceuticals, Inc., a
Florida corporation having an address at 324 South Hyde Park Avenue, Suite 350, Tampa, Florida 33606 (hereinafter “Accentia”), and Dennis Ryll, an individual with an address at 2595 Red Springs Drive, Las Vegas, Nevada 89135 (hereinafter
“Lender”). Capitalized terms not otherwise defined herein shall have the meanings ascribed to them in the Note. 

WHEREAS, Accentia and Lender entered into the Note effective November 17, 2010, which Note remains in full force and effect; and

 WHEREAS, Accentia and Lender wish to enter into this Amendment to memorialize their understanding and agreement as to the
temporary suspension, accrual and deferral of certain installment payment obligations of Accentia under the Note, as well as the extension of the Maturity Date thereunder; 
 NOW, THEREFORE, in consideration of the mutual premises and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

 1. Effective immediately upon the execution of this Amendment and for a period of nine months from the Effective Date of this
Amendment (the “Suspension Period”) the provisions of section 5 of the Note pertaining to Accentia’s quarterly payments of each Automatic Conversion Amount beginning with the Automatic Conversion Amount due on August 17, 2012

 2. During the Suspension Period, the obligations of Accentia to make payment of the Automatic Conversion Amounts as described in section 5 of the Note shall be suspended. For purposes of clarification,

Suspension Period. 
 3. The Maturity Date of the Note as set forth in Section 4 of the Note shall be extended from
August 17, 2012 through and including the final day of the Suspension Period, February 17, 2013. All outstanding principal and accrued interest under the Noteshall be due and payable in a single installment to be calculated and made in
accordance with the payment provisions set forth in Section 5 (a) – (g) of the Note.

 Section 2.1
Definitions. 
 “Acquired Indebtedness” means Indebtedness of a Person (1) existing at the time such
Person becomes a Restricted Subsidiary or (2) assumed in connection with acquisitions of Properties from such Person (other than any Indebtedness incurred in connection with, or in contemplation of, such Person becoming a Restricted Subsidiary
or such acquisition). Acquired Indebtedness shall be deemed to be incurred on the date the acquired Person becomes a Restricted Subsidiary or the date of the related acquisition of Properties from such Person. 

“Act,” when used with respect to any Holder, has the meaning specified in Section 13.3. 

“Additional Assets” means: 
 (i) any Property (other than cash, Cash Equivalents or securities) used in the Oil and Gas Business or any business ancillary thereto;

(iii) the acquisition from third parties of Capital Stock of a Restricted Subsidiary; or 

(iv) capital expenditures by the Company or a Restricted Subsidiary in the Oil and Gas Business. 

“Adjusted Consolidated Net Tangible Assets” means (without duplication), as of the date of determination, the remainder of:

 (i) the sum of:

financial statements are available, as increased by, as of the date of determination, the estimated discounted future net revenues from: 
 (1) estimated proved oil and gas reserves acquired since such year-end, which reserves were not reflected in such year-end reserve report, and 

(2) estimated oil and gas reserves attributable to upward revisions of estimates of proved oil and gas reserves since such
year-end due to exploration, development or exploitation activities, in each case calculated in accordance with Commission guidelines (utilizing the prices utilized in such year-end reserve report), 

  
 4 

 and decreased by, as of the date of determination, the estimated discounted future net
revenues from: 
 (3) estimated proved oil and gas reserves produced or disposed of since such year-end, and

 (4) estimated oil and gas reserves attributable to downward revisions of estimates of proved oil and gas
reserves since such year-end due to changes in geological conditions or other factors which would, in accordance with standard industry practice, cause such revisions, in each case calculated in accordance with Commission guidelines (utilizing the
prices utilized in such year-end reserve report); 
 provided that, in the case of each of the determinations made
pursuant to clauses (1) through (4), such increases and decreases shall be as estimated by the Company’s petroleum engineers, unless there is a Material Change as a result of such acquisitions, dispositions or revisions, in which event the
discounted future net revenues utilized for purposes of this clause (i)(a) shall be confirmed in writing by a nationally recognized firm of independent petroleum engineers; 

(b) the capitalized costs that are attributable to oil and gas properties of the Company and its Restricted Subsidiaries
to which no proved oil and gas reserves are attributable, based on the Company’s books and records as of a date no earlier than the date of the Company’s latest annual or quarterly financial statements; 

(c) the Net Working Capital on a date no earlier than the date of the Company’s latest annual or quarterly financial
statements; and 
 (d) the greater of (1) the net book value on a date no earlier than the date of the
Company’s latest annual or quarterly financial statements and (2) the appraised value, as estimated by independent appraisers, of other tangible assets (including, without duplication, Investments in unconsolidated Restricted Subsidiaries)
of the Company and its Restricted Subsidiaries, as of a date no earlier than the date of the Company’s latest audited financial statements; minus 
 (ii) the sum of: 
 (a) Minority Interests; 

(b) any net gas balancing liabilities of the Company and its Restricted Subsidiaries reflected in the Company’s
latest audited financial statements; 
 (c) to the extent included in (i)(a) above, the discounted future
net revenues, calculated in accordance with Commission guidelines (utilizing the prices utilized in the Company’s year-end reserve report), attributable to reserves which are required to be delivered to third parties to fully satisfy the
obligations of the Company and its Restricted Subsidiaries with respect to Volumetric Production Payments (determined, if applicable, using the schedules specified with respect thereto); and 

  
 5 

 (d) the discounted future net revenues, calculated in accordance with
Commission guidelines, attributable to reserves subject to Dollar-Denominated Production Payments which, based on the estimates of production and price assumptions included in determining the discounted future net revenues specified in
(i)(a) above, would be necessary to fully satisfy the payment obligations of the Company and its Restricted Subsidiaries with respect to Dollar-Denominated Production Payments (determined, if applicable, using the schedules specified with

 ARTICLE III. 
 THE NOTES 
 Section 3.1 Title and Terms.

 The Notes shall be titled the “9 1/2% Senior Notes due 2020.” Provisions relating to the Notes are
set forth in Appendix A, which is hereby incorporated in and expressly made a part of this Supplemental Indenture. The Notes and the Trustee’s certificate of authentication shall be substantially in the form of Appendix A which is hereby
incorporated in and expressly made a part of this Supplemental Indenture. The Notes may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Company is subject, if any, or usage, provided that
any such notation, legend or endorsement is in a form reasonably acceptable to the Company. Each Note shall be dated the date of its authentication. The terms of the Notes set forth in Appendix A are part of the terms of this Supplemental Indenture.

 Subject to compliance with Section 9.12, the Company may issue an unlimited amount of Additional Notes from time
to time after the Issue Date which shall have identical terms as the Notes issued on the Issue Date, other than with respect to the issue price and the date of issuance. The Notes issued on the Issue Date and any Additional Notes shall be part of
the same series of Securities for all purposes of the Original Indenture. 
 With respect to any Additional Notes, there shall
be established in or pursuant to a resolution of the Board of Directors and, subject to Section 3.3, set forth or determined in the manner provided in an Officers’ Certificate, or established in one or more indentures supplemental to the
Indenture, prior to the issuance of such Additional Notes: 
 (1) the aggregate principal amount of such Additional Notes to be
authenticated and delivered; 
 (2) the issue price and issuance date of such Additional Notes, including the date from which
interest on such Additional Notes shall accrue; and 
 (3) if applicable, that such Additional Notes shall be issuable in whole
or in part in the form of one or more Global Notes and, in such case, the respective depositories for such Global Notes, the form of any legend or legends which shall be borne by any such Global Note in addition to or in lieu of that set forth in
Appendix A and any circumstances in addition to or in lieu of those set forth in Section 3.13 in which any such Global Note may be exchanged in whole or in part for Notes registered, and any transfer of such Global Note in whole or in part
may be registered, in the name or names of Persons other than the depository for such Global Note or a nominee thereof. 
 If
any of the terms of any Additional Notes are established by action taken pursuant to a resolution of the Board of Directors, a copy of an appropriate record of such action shall be certified by the Secretary or any Assistant Secretary of the Company
and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate or the indenture supplemental hereto setting forth the terms of such issuance. 
 The Trustee shall have the right to decline to authenticate and deliver any Additional Notes under this Section if the Trustee determines that such action may not lawfully be taken by the Company or if
the Trustee in good faith by its board of directors or board of trustee, executive committee, or a trust committee of directors or trustees or Trust Officers shall determine that such action would expose the Trustee to personal liability to existing
Notes Holders. 

  
 30 

 Section 3.2 Form and Dating. 

(a) Notes shall be issued initially in the form of one or more permanent global Notes in definitive, fully registered form without
interest coupons with the global securities legend set forth in Appendix A hereto (each, a “Global Note”), which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Note Custodian, and registered in the
name of the Depository or a nominee of the Depository, duly executed by the Company and authenticated by the Trustee as provided in the Indenture. The aggregate principal amount of the Global Notes may from time to time be increased or decreased by
adjustments made on the records of the Trustee and the Depository or its nominee as hereinafter provided. The OID legend set forth in Appendix A shall be placed on all Notes issued under the Indenture that have more than a de minimis amount
of original issue discount for U.S. federal income tax purposes. 
 (b) Book-Entry Provisions. This
Section 3.2(b) shall apply only to a Global Note deposited with or on behalf of the Depository. 
 The Company shall
execute and the Trustee shall, in accordance with this Section 3.2(b) and pursuant to an order of the Company, authenticate and deliver initially one or more Global Notes that (a) shall be registered in the name of the Depository for
such Global Note or Global Notes or the nominee of such Depository and (b) shall be delivered by the Trustee to such Depository or pursuant to such Depository’s instructions or held by the Trustee as Note Custodian. 

Members of, or participants in, the Depository (“Agent Members”) shall have no rights under the Indenture with respect to any
Global Note held on their behalf by the Depository or by the Trustee as Note Custodian or under such Global Note, and the Depository may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such
Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization
furnished by the Depository or impair, as between the Depository and its Agent Members, the operation of customary practices of such Depository governing the exercise of the rights of a holder of a beneficial interest in any Global Note. 

(c) Except as provided in Sections 3.13 or 3.14, owners of beneficial interests in Global Notes will not be entitled to receive
physical delivery of certificated Notes. 
 Section 3.3 Authentication. 

The Trustee shall authenticate and deliver: (1) Notes for original issue in an aggregate principal amount of $300,000,000 and
(2) Additional Notes in an unlimited amount (subject only to the Company’s compliance with Section 9.12), if and when issued, upon a written order of the Company signed by two Officers of the Company. Such order shall specify the
amount of the Notes to be authenticated and the date on which the original issue of such Notes is to be authenticated. Except as set forth in Section 9.12, the aggregate principal amount of Notes that may be outstanding at any time is
unlimited. 

  
 31 

 Two Officers of the Company shall sign the Notes for the Company by manual or facsimile
signature. The Company’s seal may be impressed, affixed, imprinted or reproduced on the Notes and may be in facsimile form. 
 If an Officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Notes, the Notes shall be valid nevertheless. 

Notes shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Notes. The
signature shall be conclusive evidence that the Note has been authenticated under this Indenture. 
 The Trustee may appoint an
authenticating agent reasonably acceptable to the Company to authenticate the Notes. Unless limited by the terms of such appointment, an authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Supplemental
Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands. 

Section 3.4 Registrar and Paying Agent. 
 The Company shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (the “Registrar”) and an office or agency where Notes may be presented
for payment (the “Paying Agent”). The Registrar shall keep a register (the “Register”) of the Notes and of their transfer and exchange. The Company may have one or more co-registrars and one or more additional paying agents. The
term “Paying Agent” includes any additional paying agent. 
 The Company shall enter into an appropriate agency
agreement with any Registrar, Paying Agent or co-registrar not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall
notify the Trustee of the name and address of any such agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 6.6. The
Company may act as Paying Agent, Registrar, co-registrar or transfer agent. 
 The Company initially appoints the Trustee as
Registrar and Paying Agent in connection with the Notes. 
 Section 3.5 Paying Agent To Hold Money in Trust.

 Not later than 10:00 a.m., New York City time, on each due date of the principal and interest on the Notes, the Company shall
deposit with the Paying Agent a sum sufficient to pay such principal and interest when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the
benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of or interest on the Notes and shall notify the Trustee of any default by the Company in making any such payment. If the Company acts as Paying Agent,
it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent.
Upon complying with this Section, the Paying Agent shall have no further liability for the money delivered to the Trustee. 

  
 32 

 Section 3.6 Holder Lists. 

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and
addresses of Holders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee, in writing at least five Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in
such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders. 
 Section 3.7
Replacement Securities. 
 If a mutilated Note is surrendered to the Registrar or if the Holder claims that such Note has
been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Note if the requirements of Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies any other reasonable
requirements of the Trustee. If required by the Trustee or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of the Company and the Trustee to protect the Company, the Trustee, the Paying Agent, the Registrar and
any co-registrar from any loss which any of them may suffer if a Note is replaced. The Company and the Trustee may charge the Holder for their expenses in replacing a Note. 
 Every replacement Note is an additional obligation of the Company. 

Section 3.8 Outstanding Securities. 
 Notes Outstanding at any time are all Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section as not Outstanding. A
Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note. 
 If a Security is
replaced pursuant to Section 3.7, it ceases to be Outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Note is held by a protected purchaser. 

If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date money
sufficient to pay all principal and interest payable on that date with respect to the Notes (or portions thereof) to be redeemed or maturing, as the case may be, and the Paying Agent is not prohibited from paying such money to the Holders on that
date pursuant to the terms of this Indenture, then on and after that date such Notes (or portions thereof) cease to be outstanding and interest on them ceases to accrue. 

  
 33 

 Section 3.9 Temporary Notes. 

Until definitive Notes are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Notes. Temporary
Notes shall be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for temporary Notes. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive
Notes and deliver them in exchange for temporary Notes. 
 Section 3.10 Cancellation. 

The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the
Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall, in accordance with its then customary procedures, cancel and destroy (subject to the record retention requirements of the
Exchange Act) all Notes surrendered for registration of transfer, exchange, payment or cancellation and shall, upon written request, deliver a certificate of such destruction to the Company. The Company may not issue new Notes to replace Notes it
has redeemed, paid or delivered to the Trustee for cancellation. 
 Section 3.11 Defaulted Interest. 

If the Company defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the
extent lawful, interest payable on the defaulted interest, to the persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 9.1 hereof. The Company shall fix or cause to be fixed
any such special record date and payment date to the reasonable satisfaction of the Trustee and shall promptly mail to each Holder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid.

 Section 3.12 CUSIP Numbers. 
 The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to
Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only
on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee, in writing, of any change in the “CUSIP”
numbers. 
 Section 3.13 Transfer and Exchange. 

(a) Transfer and Exchange of Certificated Notes. When certificated Notes are presented to the Registrar or a co-registrar with a request:

 (1) to register the transfer of such certificated Notes; or 

(2) to exchange such certificated Notes for an equal principal amount of certificated Notes of other authorized
denominations, 

  
 34 

 
the Registrar or co-registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided, however, that the
certificated Notes surrendered for transfer or exchange: 
 (1) shall be duly endorsed or accompanied by a
written instrument of transfer in form reasonably satisfactory to the Company and the Registrar or co-registrar, duly executed by the Holder thereof or his attorney duly authorized in writing; and 

(2) are being transferred or exchanged pursuant to an effective registration statement under the Securities Act, pursuant
to Section 3.13(b) or pursuant to clause (a) or (b) below, and are accompanied by the following additional information and documents, as applicable: 

(a) if such certificated Notes are being delivered to the Registrar by a Holder for registration in the name of such
Holder, without transfer, a certification from such Holder to that effect; or 
 (b) if such certificated Notes
are being transferred to the Company, a certification to that effect. 
 (b) Restrictions on Transfer of a Certificated Note for
a Beneficial Interest in a Global Note. A certificated Note may not be exchanged for a beneficial interest in a Global Note except upon satisfaction of the requirements set forth below. Upon receipt by the Trustee of a certificated Note, duly
endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Registrar or co-registrar, together with written instructions directing the Trustee to make, or to direct the Note Custodian to make,
an adjustment on its books and records with respect to such Global Note to reflect an increase in the aggregate principal amount of the Notes represented by the Global Note, such instructions to contain information regarding the Depository account
to be credited with such increase, then the Trustee shall cancel such certificated Note and cause, or direct the Note Custodian to cause, in accordance with the standing instructions and procedures existing between the Depository and the Note
Custodian, the aggregate principal amount of Notes represented by the Global Note to be increased by the aggregate principal amount of the certificated Note to be exchanged and shall credit or cause to be credited to the account of the Person
specified in such instructions a beneficial interest in the Global Note equal to the principal amount of the certificated Note so canceled. If no Global Notes are then outstanding and the Global Note has not been previously exchanged pursuant to
Section 3.14, the Company shall issue and the Trustee shall authenticate, upon written order of the Company in the form of an Officers’ Certificate, a new Global Note in the appropriate principal amount. 

(c) Transfer and Exchange of Global Notes. 
 (1) The transfer and exchange of Global Notes or beneficial interests therein shall be effected through the Depository, in accordance with the Indenture (including applicable restrictions on transfer set
forth herein, if any) and the procedures of the Depository therefor. A transferor of a beneficial interest in a Global Note shall deliver a written order given in accordance with the Depository’s procedures containing information regarding the
participant account of the Depository to be credited with a 

  
 35 

 
beneficial interest in the Global Note and such account shall be credited in accordance with such instructions with a beneficial interest in the Global Note and the account of the Person making
the transfer shall be debited by an amount equal to the beneficial interest in the Global Note being transferred. 
 (2) If the proposed transfer is a transfer of a beneficial interest in one Global Note to a beneficial interest in another Global Note, the Registrar shall reflect on its books and records the date and an
increase in the principal amount of the Global Note to which such interest is being transferred in an amount equal to the principal amount of the interest to be so transferred, and the Registrar shall reflect on its books and records the date and a
corresponding decrease in the principal amount of Global Note from which such interest is being transferred. 

(3) Notwithstanding any other provisions of this Indenture (other than the provisions set forth in Section 3.14 of
this Indenture), a Global Note may not be transferred as a whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such
nominee to a successor Depository or a nominee of such successor Depository. 
 (d) Cancellation or Adjustment of Global Note.
At such time as all beneficial interests in a Global Note have either been exchanged for certificated Notes, redeemed, repurchased or canceled, such Global Note shall be returned by the Depository to the Trustee for cancellation or retained and
canceled by the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for certificated Notes, redeemed, repurchased or canceled, the principal amount of Notes represented by such Global Note shall
be reduced and an adjustment shall be made on the books and records of the Trustee (if it is then the Note Custodian for such Global Note) with respect to such Global Note, by the Trustee or the Note Custodian, to reflect such reduction. 

(e) Obligations with Respect to Transfers and Exchanges of Notes. 

(1) To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate
certificated Notes and Global Notes at the Registrar’s or co-registrar’s request. 
 (2) No service
charge shall be made for any registration of transfer or exchange, but the Company and the Trustee may require payment of a sum sufficient to cover any transfer tax, assessments, or similar governmental charge payable in connection therewith (other
than any such transfer taxes, assessments or similar governmental charge payable upon exchange or transfer pursuant to Section 8.6, 9.16, 9.17 and 10.6 of the Indenture). 

(3) The Registrar or co-registrar shall not be required to register the transfer of or exchange of any Note for a period
beginning 15 days before the mailing of a notice of redemption or an offer to repurchase Notes or 15 days before an interest payment date. 

  
 36 

 (4) Prior to the due presentation for registration of transfer of any Note,
the Company, the Trustee, the Paying Agent, the Registrar or any co-registrar may deem and treat the person in whose name a Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on
such Note and for all other purposes whatsoever, whether or not such Note is overdue, and none of the Company, the Trustee, the Paying Agent, the Registrar or any co-registrar shall be affected by notice to the contrary. 

(5) All Notes issued upon any transfer or exchange pursuant to the terms of the Indenture shall evidence the same debt and
shall be entitled to the same benefits under the Indenture as the Notes surrendered upon such transfer or exchange. 
 (f) No
Obligation of the Trustee. 
 (1) The Trustee shall have no responsibility or obligation to any beneficial owner
of a Global Note, a member of, or a participant in the Depository or any other Person with respect to the accuracy of the records of the Depository or its nominee or of any participant or member thereof, with respect to any ownership interest in the
Notes or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depository) of any notice (including any notice of redemption or repurchase) or the payment (or any delay in payment) of any amount,
under or with respect to such Notes. All notices and communications to be given to the Holders and all payments to be made to Holders under the Notes shall be given or made only to the registered Holders (which shall be the Depository or its nominee
in the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised only through the Depository subject to the applicable rules and procedures of the Depository. The Trustee may rely and shall be fully protected in
relying upon information furnished by the Depository with respect to its members, participants and any beneficial owners. 
 (2) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under the Indenture or under applicable law with respect to any
transfer of any interest in any Note (including any transfers between or among Depository participants, members or beneficial owners 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 the Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. 

Section 3.14 Certificated Notes. 
 (a) Notwithstanding any other provision in the Indenture, no Global Note may be exchanged in whole or in part for Notes registered, and no transfer of a Global Note in whole or in part may be registered,
in the name of any Person other than the Depositary for such Global Note or a nominee thereof, unless (A) such Depositary (i) has notified the Company that it is no longer willing or able to discharge its responsibilities properly as
Depositary for such Global Note or (ii) has ceased to be a clearing agency registered under the Exchange Act, and in either case the Company has not appointed a qualified successor within 90 days, (B) an Event of Default has occurred
and is continuing and the Depositary has notified the Company and the Trustee of its desire to exchange such Global Note for Certificated Notes or (C) subject to the Depositary’s rules, the Company, at its option, has elected to terminate
the book-entry system through the Depositary. 

  
 37 

 (b) Every Note authenticated and delivered upon registration of transfer of, or in exchange
for or in lieu of, a Global Note or any portion thereof, whether pursuant to this Section or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Note, unless such Note is registered in the name of a Person other
than the Depositary for such Global Note or a nominee thereof. 
 (c) Any Global Note that is transferable to the beneficial
owners thereof pursuant to this Section 3.14 shall be surrendered by the Depository to the Trustee, to be so transferred, in whole or from time to time in part, without charge, and the Trustee shall authenticate and deliver, upon such transfer
of each portion of such Global Note, an equal aggregate principal amount of certificated Notes of authorized denominations. Any portion of a Global Note transferred pursuant to this Section shall be executed, authenticated and delivered only in
denominations of $2,000 and any integral multiple of $1,000 in excess thereof and registered in such names as the Depository shall direct. 
 (d) Subject to the provisions of Section 3.14(c), the registered 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 which a Holder is entitled to take under the Indenture or the Notes. 
 (e)
In the event of the occurrence of any of the events specified in Section 3.14(a), the Company will promptly make available to the Trustee a reasonable supply of certificated Notes in definitive, fully registered form without interest coupons.

 ARTICLE IV. 
 SATISFACTION AND DISCHARGE 
 Section 4.1 Satisfaction and Discharge
of Indenture. 
 The Indenture shall upon Company Request cease to be of further effect (except as to surviving rights of
registration of transfer or exchange of Notes, as expressly provided for in the Indenture) as to all Outstanding Notes, and the Trustee, at the expense of the Company, shall, upon payment of all amounts due the Trustee under Section 6.6 hereof,

last paragraph of Section 9.3 hereof shall survive. 
 Section 4.2 Application of Trust Money.

 Subject to the provisions of the last paragraph of Section 9.3 hereof, all money deposited with the Trustee pursuant to
Section 4.1 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent)
as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee. 

  
 39 

 ARTICLE V. 
 DEFAULTS AND REMEDIES

 Section 5.2
Acceleration of Maturity; Rescission and Annulment. 
 If an Event of Default (other than an Event of Default specified
in Section 5.1(i) or (j) hereof) occurs and is continuing, the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes then Outstanding, by written notice to the Company (and to the Trustee if such
notice is given by the Holders), may, and the Trustee upon the request of the Holders of not less than 25% in aggregate principal amount of the Outstanding Notes shall, by written notice to the Company, declare all unpaid principal of, premium, if
any, and accrued and unpaid interest on all the Notes to be due and payable immediately, upon which declaration all 

  
 41 

 
amounts payable in respect of the Notes shall be immediately due and payable. If an Event of Default specified in Section 5.1(i) or (j) hereof occurs and is continuing, the amounts
described above shall become and be immediately due and payable without any declaration, notice or other act on the part of the Trustee or any Holder. 
 At any time after a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the
Holders of a majority in aggregate principal amount of the Outstanding Notes, by written notice to the Company, the Subsidiary Guarantors and the Trustee, may rescind and annul such declaration and its consequences if: 

(a) the Company or any Subsidiary Guarantor has paid or deposited with the Trustee a sum sufficient to pay, 

(1) all overdue interest on all Outstanding Notes, 

(2) all unpaid principal of (and premium, if any, on) any Outstanding Notes which have become due otherwise than by such
declaration of acceleration, including any Notes required to have been purchased on a Change of Control Date or a Purchase Date pursuant to a Change of Control Offer or a Prepayment Offer, as applicable, and interest on such unpaid principal at the
rate borne by the Notes, 
 (3) to the extent that payment of such interest is lawful, interest on overdue
interest and overdue principal at the rate borne by the Notes (without duplication of any amount paid or deposited pursuant to clauses (1) and (2) above), and 

(4) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel; 
 (b) the rescission would not conflict with any judgment or decree of a court
of competent jurisdiction as certified to the Trustee by the Company; and 
 (c) all Events of Default, other than the
non-payment of amounts of principal of (or premium, if any, on) or interest on Notes which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13 hereof. 

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

Notwithstanding the foregoing, if an Event of Default specified in Section 5.1(f) hereof shall have occurred and be continuing,
such Event of Default and any consequential acceleration shall be automatically rescinded if the Indebtedness that is the subject of such Event of Default has been repaid, or if the default relating to such Indebtedness is waived or cured and if
such Indebtedness has been accelerated, then the holders thereof have rescinded their declaration of acceleration in respect of such Indebtedness (provided, in each case, that such repayment, waiver, cure or rescission is effected within a period of
10 days from the continuation of such default beyond the applicable grace period or the occurrence of such acceleration), and written 

  
 42 

 
notice of such repayment, or cure or waiver and rescission, as the case may be, shall have been given to the Trustee by the Company and countersigned by the holders of such Indebtedness or a
trustee, fiduciary or agent for such holders or other evidence satisfactory to the Trustee of such events is provided to the Trustee, within 30 days after any such acceleration in respect of the Notes, and so long as such rescission of any such
acceleration of the Notes does not conflict with any judgment or decree as certified to the Trustee by the Company. 

Section 5.3 Collection of Indebtedness and Suits for Enforcement by Trustee. 

The Company covenants that if 
 (a) default is made in the payment of any installment of interest on any Note when such interest becomes due and payable and such default continues for a period of 30 days, or 

(b) default is made in the payment of the principal of (or premium, if any, on) any Note at the Maturity thereof or with respect to any
Note required to have been purchased by the Company on the Change of Control Purchase Date or the Purchase Date pursuant to a Change of Control Offer or Prepayment Offer, as applicable, then the Company will, upon demand of the Trustee, pay to the
Trustee for the benefit of the Holders of such Notes, the whole amount then due and payable on such Notes for principal (and premium, if any) and interest, and interest on any overdue principal (and premium, if any) and, to the extent that payment
of such interest shall be legally enforceable, upon any overdue installment of interest, at the rate borne by the Notes, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including
the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
 If the Company
fails to pay such amounts forthwith upon such demand, the Trustee, in its own name as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or
final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the money adjudged or decreed to be payable in the manner provided by law out of the Property of the Company or any other obligor upon the
Notes, wherever situated. 
 If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement
in the Indenture or in aid of the exercise of any power granted in the Indenture, or to enforce any other proper remedy. 

Section 5.4 Trustee May File Proofs of Claim. 
 In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company, any Subsidiary
Guarantor or any other obligor upon the Notes, their creditors or the Property of the Company, of any Subsidiary Guarantor or of any such other obligor, the Trustee (irrespective of whether the principal of the Notes shall then be due and payable as
therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company, the Subsidiary Guarantors or such other obligor for the payment of overdue principal, premium, if any, or interest)
shall be entitled and empowered, by intervention in such proceeding or otherwise, 

  
 43 

 (a) to file and prove a claim for the whole amount of principal (and premium, if any) and
interest owing and unpaid in respect of the Notes and to file such other papers or documents and take any other actions including participation as a full member of any creditor or other committee as may be necessary or advisable in order to have the
claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and 

(b) to collect and receive any money or other Property payable or deliverable on any such claims and to distribute the same; 

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay 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 6.6 hereof. 
 Nothing
herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the Subsidiary Guarantees or
the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 Section 5.5 Trustee May Enforce Claims Without Possession of Notes. 

All rights of action and claims under the Indenture or the Notes or the Subsidiary Guarantees may be prosecuted and enforced by the
Trustee without the possession of any of the Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name and as trustee of an express trust, and any recovery
of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes in respect of which such judgment
has been recovered. 
 Section 5.6 Application of Money Collected. 

Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the
Trustee and, in the case of the distribution of such money on account of principal (or premium, if any) or interest, upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon surrender thereof if fully
paid: 
 FIRST: to the payment of all amounts due the Trustee under Section 6.6 hereof; 

SECOND: to the payment of the amounts then due and unpaid for principal of (and premium, if any, on) and interest on the Notes in respect
of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Notes for principal (and premium, if any) and interest, respectively; and

  
 44 

 THIRD: the balance, if any, to the Company, or to whomsoever may be lawfully entitled to
receive the same, or as a court of competent jurisdiction may direct. 
 Section 5.7 Limitation on Suits.

 No Holder of any Notes shall have any right to institute any proceeding, judicial or otherwise, with respect to the
Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless: 
 (a) such Holder has
previously given written notice to the Trustee of a continuing Event of Default; 
 (b) the Holders of not less than 25% in
aggregate principal amount of the Outstanding Notes shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 

(c) such Holder or Holders have offered to the Trustee such reasonable indemnity as the Trustee may require against the costs, expenses
and liabilities to be incurred in compliance with such request; 
 (d) the Trustee for 60 days after its receipt of such notice,
request and offer of indemnity has failed to institute any such proceeding; and 
 (e) no direction inconsistent with such
written request has been given to the Trustee during such 60-day period by the Holders of a majority or more in aggregate principal amount of the Outstanding Notes; 
 it being understood and intended that no one or more Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of the Indenture to affect, disturb or prejudice the
rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under the Indenture, except in the manner herein provided and for the equal and ratable benefit of all the Holders.

 Section 5.8 Unconditional Right of Holders to Receive Principal, Premium and Interest. 

Notwithstanding any other provision in the Indenture, the Holder of any Note shall have the right, which is absolute and unconditional,
to receive payment, as provided herein (including, if applicable, Article XI hereof) and in such Note of the principal of (and premium if any, on) and (subject to Section 3.11 hereof) interest on, such Note on the respective Stated Maturities
expressed in such Note (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 

  
 45 

 Section 5.9 Restoration of Rights and Remedies. 

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under the Indenture and such proceeding has
been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Subsidiary Guarantors, the Trustee and
the Holders shall be restored severally and respectively to their former positions hereunder and thereunder and all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 

Section 5.10 Rights and Remedies Cumulative. 
 Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 3.7 hereof, no right or remedy herein conferred upon or reserved to
the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or
hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 

Section 5.11 Delay or Omission Not Waiver. 
 No delay or omission of the Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such
Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as
the case may be. 
 Section 5.12 Control by Holders. 

The Holders of not less than a majority in aggregate principal amount of the Outstanding Notes shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, provided that 
 (a) such direction shall not be in conflict with any rule of law or with the Indenture, 
 (b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, 
 (c) the Trustee need not take any action which might involve it in personal liability, and 
 (d) the Trustee may decline to take any action that would benefit some Holders to the detriment of other Holders. 
 Prior to taking any such action under this Section, the Trustee shall be entitled to such reasonable security or indemnity as it may require against the costs, expenses and liabilities that may be
incurred by it in taking or declining to take any such action hereunder. 

  
 46 

 Section 5.13 Waiver of Past Defaults. 

Subject to Section 5.2(a)(4), the Holders of not less than a majority in aggregate principal amount of the Outstanding Notes may, on
behalf of the Holders of all the Notes, waive any existing Default or Event of Default hereunder and its consequences, except a Default or Event of Default 
 (a) in respect of the payment of the principal of (or premium, if any, on) or interest on any Note, or 
 (b) in respect of a covenant or provision hereof which under Article VIII hereof cannot be modified or amended without the consent of the Holder of each Outstanding Note affected thereby. 

Upon any such waiver, such Default or Event of Default shall cease to exist for every purpose under the Indenture, but no such waiver
shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. 
 Section 5.14
Waiver of Stay, Extension or Usury Laws. 
 Each of the Company and the Subsidiary Guarantors covenants (to the extent
that each may lawfully do so) that 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 or other law wherever enacted, now or at any time hereafter in
force, which would prohibit or forgive the Company or any Subsidiary Guarantor from paying all or any portion of the principal of (premium, if any, on) or interest on the Notes as contemplated herein, or which may affect the covenants or the
performance of the Indenture; and (to the extent that it may lawfully do so) each of the Company and the Subsidiary Guarantors hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede
the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 
 ARTICLE VI. 
 THE TRUSTEE 

Section 6.1 Duties of Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise as a

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

provided, however, that, in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions to determine whether or
not they conform to the requirements of this Indenture, but the Trustee has no obligation to determine the accuracy or completeness (other than as to conformity with the requirements of this Indenture) of the statements made therein.

misconduct, except that:

believed by it to be genuine and to have been signed or presented by the proper party or parties; 
 (b) any request or
direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order and any resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution;

taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers’ Certificate; 

(d) the Trustee may consult with counsel and the advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon; 

  
 48

incurred by it in compliance with such request or direction; 
 (f) the Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee,

Officer has actual knowledge thereof or unless written notice thereof is received by the Trustee at its Corporate Trust Office and such notice references the Notes generally, the Company or this Indenture; 

(j) the Trustee shall not be required to advance, expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder, or in the exercise of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably
assured to it; 
 (k) the Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible
Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a Default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this
Indenture; 
 (l) anything in this Indenture notwithstanding, in no event shall the Trustee be liable for any special, indirect,

 (m) the Trustee may request that the Company and, if applicable, the Guarantors 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; and 

  
 49 

 (n) the permissive rights of the Trustee enumerated herein shall not be construed as duties.

 Section 6.3 Trustee Not Responsible for Recitals or Issuance of Notes. 

The recitals contained herein and in the Notes, except for the Trustee’s certificates of authentication, shall be taken as the
statements of the Company or the Subsidiary Guarantors, as the case may be, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture, the Subsidiary
Guarantees or the Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds thereof. 
 Section 6.4 May Hold Notes. 
 The Trustee, any Paying Agent, any
Registrar or any other agent of the Company, the Subsidiary Guarantors or of the Trustee, in its individual or any other capacity, may become the owner or pledgee of Notes and, subject to TIA Sections 310(b) and 311 in the case of the Trustee, may
otherwise deal with the Company and the Subsidiary Guarantors with the same rights it would have if it were not the Trustee, Paying Agent, Registrar or such other agent. 
 Section 6.5 Money Held in Trust. 
 Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed with the Company or any Subsidiary
Guarantor. 
 Section 6.6 Compensation and Reimbursement. 

The Company agrees: 
 (a) to pay to the Trustee from time to time such compensation as the Company and the Trustee may agree in writing for all services rendered by it hereunder (which compensation shall not be limited by any
provision of law in regard to the compensation of a trustee of an express trust); 
 (b) except as otherwise expressly provided
herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the compensation and the expenses and
disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to the Trustee’s willful misconduct, negligence or bad faith; and 

(c) to indemnify the Trustee for, and to hold it harmless against, any loss, liability, claim, damage or expense incurred without willful

or performance of any of its powers or duties hereunder or (ii) in connection with enforcing this indemnification provision. 

  
 50 

 The obligations of the Company under this Section 6.6 to compensate the Trustee, to pay
or reimburse the Trustee for expenses, disbursements and advances and to indemnify and hold harmless the Trustee shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture, the resignation
or removal of the Trustee, or any other termination under any Insolvency or Liquidation Proceeding. As security for the performance of such obligations of the Company, the Trustee shall have a claim and lien prior to the Notes upon all property and
funds held or collected by the Trustee as such, except funds held in trust for payment of principal of (and premium, if any, on) or interest on Notes. Such lien shall survive the satisfaction and discharge of this Indenture or any other termination
under any Insolvency or Liquidation Proceeding. 
 When the Trustee incurs expenses or renders services after the occurrence of
an Event of Default specified in paragraph (i) or (j) of Section 5.1 of this Indenture, such expenses and the compensation for such services are intended to constitute expenses of administration under any Insolvency or Liquidation
Proceeding. 
 Section 6.7 Corporate Trustee Required; Eligibility. 

There shall at all times be a Trustee hereunder which shall be eligible to act as Trustee under TIA Section 310(a)(1) and shall have
a combined capital and surplus of at least $50,000,000. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of federal, state, territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section 6.7, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time
the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 

Section 6.8 Conflicting Interests. 
 The Trustee shall comply with the provisions of Section 310(b) of the Trust Indenture Act; provided, however, that there shall be excluded from the operation of TIA Section 310(b)(1) any
indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in TIA Section 310(b)(1) are met. 

Section 6.9 Resignation and Removal; Appointment of Successor. 

(a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective
until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 6.10 hereof. 
 (b) The Trustee may resign at any time by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 6.10 hereof shall not have been
delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may, at the expense of the Company, petition any court of competent jurisdiction for the appointment of a successor Trustee. 

  
 51 

 (c) The Trustee may be removed at any time by Act of the Holders of not less than a majority
in aggregate principal amount of the Outstanding Notes, delivered to the Trustee and to the Company. 
 (d) If at any time:

therefor by the Company or by any Holder who has been a bona fide Holder for at least six months, or 
 (2) the

necessary so that its business may be properly and advantageously conducted at all times; provided, however, that nothing in this Section 9.8 shall prevent the Company or any Restricted Subsidiary from discontinuing the maintenance of
any of such Properties if such discontinuance is, in the judgment of the Company or such Restricted Subsidiary, as the case may be, desirable in the conduct of the business of the Company or such Restricted Subsidiary and not disadvantageous in any
material respect to the Holders. Notwithstanding the foregoing, nothing contained in this Section 9.8 shall limit or impair in any way the right of the Company and its Restricted Subsidiaries to sell, divest and otherwise to engage in
transactions that are otherwise permitted by this Indenture.

corporations similarly situated and owning like Properties.

plan or method of protection, in lieu of or supplemental to insurance with insurers, whether by the establishment of an insurance fund or reserve to be held and applied to make good losses from casualties, or otherwise, conforming to the systems of

the Company’s website will be deemed to satisfy the foregoing delivery requirements.

information contained therein, including the Company’s compliance with any of the covenants contained in the Indenture (as to which the Trustee will be entitled to conclusively rely upon an Officers’ Certificate).

 Section 9.11 [Reserved.] 

Section 9.12 Limitation on Indebtedness and Disqualified Capital Stock. 

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, create, incur, assume, guarantee or in any manner
become directly or indirectly liable for the payment of (collectively, “incur”) any Indebtedness (including any Acquired Indebtedness), and the Company shall not, and shall not permit any of its Restricted Subsidiaries to, issue any
Disqualified Capital Stock (except for the issuance by the Company of Disqualified Capital Stock (a) which is redeemable at the Company’s option in cash or Qualified Capital Stock and (b) the dividends on which are payable at the
Company’s option in cash or Qualified Capital Stock); provided however, that the Company and its Restricted Subsidiaries that are Subsidiary Guarantors may incur Indebtedness or issue shares of Disqualified Capital Stock if (i) at
the time of such event and after giving effect thereto on a pro forma basis the Consolidated Fixed Charge Coverage Ratio for the four full quarters immediately preceding such event, taken as one period, would have been equal to or greater than 2.25
to 1.0 and (ii) no Default or Event of Default shall have occurred and be continuing at the time such additional Indebtedness is incurred or such Disqualified Capital Stock is issued or would occur as a consequence of the incurrence of the
additional Indebtedness or the issuance of the Disqualified Capital Stock. 
 (b) Notwithstanding the prohibitions of
Section 9.12(a), the Company and its Restricted Subsidiaries may incur any of the following items of Indebtedness (collectively, “Permitted Indebtedness”): 

  
 66 

 (1) Priority Credit Facility Debt in an aggregate amount at any one time
outstanding not to exceed the greater of (a) the Borrowing Base under the Bank Credit Agreement at such time less the sum of all repayments of principal of Priority Credit Facility Debt made pursuant to Section 9.17 hereof and (b) 25%
of Adjusted Consolidated Net Tangible Assets; provided, however, that Indebtedness and Disqualified Capital Stock of Restricted Subsidiaries that are not Subsidiary Guarantors shall not at any time constitute more than 50% of all Priority
Credit Facility Debt otherwise permitted under this clause (1); 
 (2) Indebtedness under the Notes
(excluding any Additional Notes); 
 (3) Indebtedness outstanding or in effect on the Issue Date (and not repaid
or defeased with the proceeds of the offering of the Notes); 
 (4) obligations pursuant to Interest Rate
Protection Obligations, but only to the extent such obligations do not exceed 105% of the aggregate principal amount of the Indebtedness covered by such Interest Rate Protection Obligations; obligations under currency exchange contracts entered into
in the ordinary course of business; hedging arrangements entered into in the ordinary course of business for the purpose of protecting production, purchases and resales against fluctuations in oil or natural gas prices; and any guarantee of any of
the foregoing; 
 (5) the Subsidiary Guarantees (and any assumption of the obligations guaranteed thereby);

 (6) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between
or among the Company and any of its Restricted Subsidiaries; provided, however, that: 
 (a) if the Company is
the obligor on such Indebtedness and a Subsidiary Guarantor is not the obligee, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Notes, or if a Subsidiary Guarantor is the
obligor on such Indebtedness and neither the Company nor another Subsidiary Guarantor is the obligee, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Subsidiary Guarantee
of such Subsidiary Guarantor; and 
 (b)(i) any subsequent issuance or transfer of Equity Interests that results
in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary of the Company and (ii) any sale or other transfer of any such Indebtedness to a Person that is neither the Company nor a Restricted Subsidiary of
the Company will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6); 

(7) Permitted Refinancing Indebtedness and any guarantee thereof; 

  
 67 

 (8) Non-Recourse Indebtedness; 

(9) in kind obligations relating to net oil or gas balancing positions arising in the ordinary course of business;

 (10) Indebtedness in respect of bid, performance or surety bonds issued for the account of the Company or any
Restricted Subsidiary in the ordinary course of business, including guaranties and letters of credit supporting such bid, performance or surety obligations (in each case other than for an obligation for money borrowed); and 

(11) any additional Indebtedness in an aggregate principal amount not in excess of $75,000,000 at any one time outstanding
and any guarantee thereof. 
 (c) For purposes of determining compliance with this Section 9.12, in the event that an item
of Indebtedness meets the criteria of one or more of the categories of Permitted Indebtedness described in paragraphs (b)(1) through (b)(11) above or is entitled to be incurred pursuant to Section 9.12(a), the Company may, in its sole
discretion, classify such item of Indebtedness in any manner that complies with this covenant and such item of Indebtedness will be treated as having been incurred pursuant to only one of such clauses of the definition of Permitted Indebtedness or
the proviso of the foregoing sentence and an item of Indebtedness may be divided and classified in more than one of the types of Indebtedness permitted hereunder; provided that all Indebtedness outstanding on the Issue Date under the Bank
Credit Agreement shall be deemed incurred under paragraph (b)(1) above and not under paragraph (b)(3) above. 
 (d) The accrual
of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on Disqualified Stock in the form of
additional shares of the same class of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this Section 9.12. The amount of any Indebtedness outstanding as of any date
shall be (i) the accreted value thereof in the case of any Indebtedness issued with original issue discount and (ii) the principal amount or liquidation preference thereof, together with any interest thereon that is more than 30 days past
due, in the case of any other Indebtedness. 
 (e) 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-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to
have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced (plus all accrued interest on the Indebtedness being refinanced and the amount of all
expenses and premiums incurred in connection therewith). 

  
 68 

 (f) The amount of any guarantee by the Company or any Restricted Subsidiary of any
Indebtedness of the Company or one or more Restricted Subsidiaries shall not be deemed to be outstanding or incurred for purposes of this Section 9.12 in addition to the amount of Indebtedness which it guarantees. 

(g) For purposes of this Section 9.12, Indebtedness of any Person that becomes a Restricted Subsidiary by merger, consolidation or
other acquisition shall be deemed to have been incurred by the Company and the Restricted Subsidiary at the time such Person becomes a Restricted Subsidiary. 
 (h) Notwithstanding any other provision of this Section 9.12, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 9.12 shall not
be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being
refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Permitted Refinancing Indebtedness is denominated that is in effect on the date of such refinancing. 

Section 9.13 Additional Subsidiary Guarantors. 
 (a) If any Restricted Subsidiary that is not already a Subsidiary Guarantor has outstanding or guarantees any other Indebtedness of the Company or a Subsidiary Guarantor, then in either case that
Subsidiary will become a Subsidiary Guarantor by executing a supplemental indenture and delivering it to the Trustee within 20 Business Days of the date on which it incurred or guaranteed such Indebtedness, as the case may be; provided,
however, that the foregoing shall not apply to Subsidiaries of the Company that have properly been designated as Unrestricted Subsidiaries in accordance with the Indenture for so long as they continue to constitute Unrestricted Subsidiaries.

 (b) Notwithstanding the foregoing and the other provisions of this Indenture, any Subsidiary Guarantee incurred by a
Restricted Subsidiary pursuant to this Section 9.13 shall provide by its terms that it shall be automatically and unconditionally released and discharged upon the terms and conditions set forth in Section 12.3 hereof. 

Section 9.14 Limitation on Issuances and Sales of Preferred Stock of Restricted Subsidiaries. 

The Company (a) shall not permit any Restricted Subsidiary to issue or sell any Preferred Stock to any Person other than to the
Company or one of its Wholly Owned Restricted Subsidiaries and (b) shall not permit any Person other than the Company or one of its Wholly Owned Restricted Subsidiaries to own any Preferred Stock of any other Restricted Subsidiary except, in
each case, for (i) the Preferred Stock of a Restricted Subsidiary owned by a Person at the time such Restricted Subsidiary became a Restricted Subsidiary or (ii) a sale of Preferred Stock in connection with the sale of all of the Capital
Stock of a Restricted Subsidiary owned by the Company or its Subsidiaries effected in accordance with Section 9.17 hereof. 

  
 69 

 Section 9.15 Limitation on Liens. 

The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create, incur, assume, affirm or suffer
to exist or become effective any Lien of any kind, except for Permitted Liens, upon any of their respective Properties, whether now owned or acquired after the Issue Date, or any income or profits therefrom, or assign or convey any right to receive
income thereon, unless (a) in the case of any Lien securing Subordinated Indebtedness, the Notes are secured by a lien on such Property or proceeds that is senior in priority to such Lien and (b) in the case of any other Lien, the Notes
are directly secured equally and ratably with the obligation or liability secured by such Lien. 
 Section 9.16 Purchase
of Notes Upon Change of Control. 
 (a) Upon the occurrence of a Change of Control, the Company shall be obligated to make
an offer to purchase (a “Change of Control Offer”) all of the then Outstanding Notes, in whole or in part (and if in part, in denominations of $2,000 or integral multiples of $1,000 in excess thereof), from the Holders of such Notes, at a
purchase price (the “Change of Control Purchase Price”) equal to 101% of the aggregate principal amount of such Notes, plus accrued and unpaid interest, if any, to the Change of Control Purchase Date (subject to the right of Holders of
record on the relevant Regular Record Date to receive interest due on an Interest Payment Date that is on or prior to the Change of Control Purchase Date), in accordance with the procedures set forth in paragraphs (b), (c) and (d) of this
Section. The Company shall, subject to the provisions described below, be required to purchase all Notes properly tendered into the Change of Control Offer and not withdrawn. The Company will not be required to make a Change of Control Offer upon a
Change of Control if another Person makes the Change of Control Offer at the same purchase price, at the same times and otherwise in substantial compliance with the requirements applicable to a Change of Control Offer to be made by the Company and
purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. 
 (b) The Change of Control Offer is
required to remain open for at least 20 Business Days and until the close of business on the fifth Business Day prior to the Change of Control Purchase Date. 
 (c) Not later than the 30th day following the occurrence of any Change of Control, the Company shall give to the Trustee in the manner provided in Section 13.4 and each Holder of the Notes in the
manner provided in Section 13.5, a notice (the “Change of Control Notice”) governing the terms of the Change of Control Offer and stating: 
 (1) that a Change in Control has occurred and that such Holder has the right to require the Company to repurchase such Holder’s Notes, or portion thereof, at the Change of Control Purchase Price;

 (2) any information regarding such Change of Control required to be furnished pursuant to Rule 13e-1 under the
Exchange Act and any other securities laws and regulations thereunder; 
 (3) a purchase date (the “Change
of Control Purchase Date”), which shall be on a Business Day and no earlier than 30 days nor later than 60 days from the date the Change of Control occurred; 

  
 70 

 (4) that any Note, or portion thereof, not tendered or accepted for payment
will continue to accrue interest: 
 (5) that unless the Company defaults in depositing money with the Paying
Agent in accordance with the last paragraph of clause (d) of this Section 9.16, or payment is otherwise prevented, any Note, or portion thereof, accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest
after the Change of Control Purchase Date; and 
 (6) the instructions a Holder must follow in order to have his
Notes repurchased in accordance with paragraph (d) of this Section. 
 If any of the Notes subject to the Change of Control Offer is in the
form of a Global Note, then the Company shall modify the Change of Control Notice to the extent necessary to accord with the procedures of the depository applicable thereto. 
 (d) Holders electing to have Notes purchased will be required to surrender such Notes to the Paying Agent at the address specified in the Change of Control Notice at least five Business Days prior to the
Change of Control Purchase Date. Holders will be entitled to withdraw their election if the Paying Agent receives, not later than three Business Days prior to the Change of Control Purchase Date, a telegram, telex, facsimile transmission or letter
setting forth the name of the Holder and principal amount of the Notes delivered for purchase by the Holder as to which his election is to be withdrawn and a statement that such Holder is withdrawing his election to have such Notes purchased.
Holders whose Notes are purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered. 
 On the Change of Control Purchase Date, the Company shall (i) accept for payment Notes or portions thereof validly tendered pursuant to a Change of Control Offer, (ii) deposit with the Paying
Agent money sufficient to pay the purchase price of all Notes or portions thereof so tendered, and (iii) deliver or cause to be delivered to the Trustee the Notes so accepted. The Paying Agent shall promptly mail or deliver to Holders of the
Notes so tendered payment in an amount equal to the purchase price for the Notes, and the Company shall execute and the Trustee shall authenticate and mail or make available for delivery to such Holders a new Note equal in principal amount to any
unpurchased portion of the Note which any such Holder did not surrender for purchase. The Company shall announce the results of a Change of Control Offer on or as soon as practicable after the Change of Control Purchase Date. For purposes of this
Section 9.16, the Trustee will act as the Paying Agent. 
 (e) If Holders of not less than 90% in aggregate principal amount
of the Outstanding Notes validly tender and do not withdraw such notes in a Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company as described above, purchases all of the Notes validly
tendered and not withdrawn by such Holders, the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer described above,
to redeem all Notes that remain outstanding following such purchase at a redemption price in cash equal to the applicable Change of Control Purchase Price plus, to the extent not included in the Change of Control Purchase Price, accrued and unpaid
interest, if any, to the date of redemption. 

  
 71 

 (f) The Company shall comply with Rule 14e-1 under the Exchange Act and any other securities
laws and regulations thereunder to the extent such laws and regulations are applicable, in the event that a Change of Control occurs and the Company is required to purchase Notes as described in this Section 9.16. 

Section 9.17 Limitation on Asset Sales. 
 (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, consummate any Asset Sale unless (i) the Company or such Restricted Subsidiary, as the case may be, receives
consideration at the time of such Asset Sale at least equal to the Fair Market Value of the Property subject to such Asset Sale and (ii) all of the consideration paid to the Company or such Restricted Subsidiary in connection with such Asset
Sale is in the form of cash, Cash Equivalents, Liquid Securities, Exchanged Properties or the assumption by the purchaser of liabilities of the Company (other than liabilities of the Company that are by their terms subordinated to the Notes) or
liabilities of any Subsidiary Guarantor that made such Asset Sale (other than liabilities of a Subsidiary Guarantor that are by their terms subordinated to such Subsidiary Guarantor’s Subsidiary Guarantee), in each case as a result of which the
Company and its remaining Restricted Subsidiaries are no longer liable for such liabilities (“Permitted Consideration”); provided, however, that the Company and its Restricted Subsidiaries shall be permitted to receive Property
other than Permitted Consideration, so long as the aggregate Fair Market Value of all such Property other than Permitted Consideration received from Asset Sales since the 2009 Notes Issue Date and held by the Company or any Restricted Subsidiary at
any one time shall not exceed 10% of Adjusted Consolidated Net Tangible Assets. The Net Available Cash from Asset Sales by the Company or a Restricted Subsidiary may be applied by the Company or such Restricted Subsidiary, to the extent the Company
or such Restricted Subsidiary elects (or is required by the terms of any Senior Indebtedness of the Company or a Restricted Subsidiary), to (i) prepay, repay, redeem or purchase Senior Indebtedness of the Company or a Restricted Subsidiary; or
(ii) reinvest in Additional Assets (including by means of an Investment in Additional Assets by a Restricted Subsidiary with Net Available Cash received by the Company or another Restricted Subsidiary). 

(b) Any Net Available Cash from an Asset Sale not applied in accordance with the preceding paragraph within 365 days from the date of
such Asset Sale shall constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $10,000,000, the Company shall be required to make an offer (the “Prepayment Offer”) to all Holders of Notes and all Holders
of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth herein with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount of Notes and
such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Prepayment Offer will be equal to 100% of principal amount plus accrued and unpaid interest, if any, to the Purchase Date (subject to the
right of Holders of record on the relevant Regular Record Date to receive interest due on an Interest Payment Date that is on or prior to the Purchase Date), and will be payable in cash. If the aggregate principal amount of Notes tendered by Holders
thereof exceeds the amount of available Excess Proceeds allocated for repurchases of Notes pursuant to the Prepayment Offer for Notes, then such Excess Proceeds will be allocated 

  
 72 

 
pro rata according to the principal amount of the Notes tendered and the Trustee will select the Notes to be purchased in accordance with this Indenture. To the extent that any portion of the
amount of Excess Proceeds remains after compliance with the second sentence of this paragraph and provided that all Holders of Notes have been given the opportunity to tender their Notes for purchase as described in the following paragraph in
accordance with this Indenture, the Company and its Restricted Subsidiaries may use such remaining amount for purposes permitted by this Indenture and the amount of Excess Proceeds shall be reset to zero. 

(c) (i) Within 30 days after the 365th day following the date of an Asset Sale, the Company shall, if it is obligated to make an offer to
purchase the Notes pursuant to the preceding paragraph, send a written Prepayment Offer notice, by first-class mail, to the Trustee and the Holders of the Notes (the “Prepayment Offer Notice”), accompanied by such information regarding the
Company and its Subsidiaries as the Company believes shall enable such Holders of the Notes to make an informed decision with respect to the Prepayment Offer (which at a minimum shall include (A) the most recently filed Annual Report on Form
10-K (including audited consolidated financial statements) of the Company, the most recent subsequently filed Quarterly Report on Form 10-Q of the Company and any Current Report on Form 8-K of the Company filed subsequent to such Quarterly Report,
other than Current Reports describing Asset Sales otherwise described in the offering materials, or corresponding successor reports (or, during any time that the Company is not subject to the reporting requirements of Section 13 or
15(d) of the Exchange Act, corresponding reports prepared pursuant to Section 9.9), (B) a description of material developments in the Company’s business subsequent to the date of the latest of such reports and (C) if
material, appropriate pro forma financial information). The Prepayment Offer Notice shall state, among other things, (1) that the Company is offering to purchase Notes pursuant to the provisions of this Indenture, (2) that any Note (or any
portion thereof) accepted for payment (and duly paid on the Purchase Date) pursuant to the Prepayment Offer shall cease to accrue interest on the Purchase Date, (3) that any Notes (or portions thereof) not properly tendered shall continue to
accrue interest, (4) the purchase price and purchase date, which shall be, subject to any contrary requirements of applicable law, no less than 30 days nor more than 60 days after the date the Prepayment Offer Notice is mailed (the
“Purchase Date”), (5) the aggregate principal amount of Notes to be purchased, (6) a description of the procedure which Holders of Notes must follow in order to tender their Notes and the procedures that Holders of Notes must
follow in order to withdraw an election to tender their Notes for payment and (7) all other instructions and materials necessary to enable Holders to tender Notes pursuant to the Prepayment Offer. 

(ii) Not later than the date upon which written notice of a Prepayment Offer is delivered to the Trustee as provided
above, the Company shall deliver to the Trustee an Officers’ Certificate as to (1) the amount of the Prepayment Offer (the “Offer Amount”), (2) the allocation of the Net Available Cash from the Asset Sales pursuant to which
such Prepayment Offer is being made and (3) the compliance of such allocation with the provisions of Section 9.17(a). On such date, the Company shall also irrevocably deposit with the Trustee or with the Paying Agent (or, if the Company is
the Paying Agent, shall segregate and hold in trust) in cash an amount equal to the Offer Amount to be held for payment in accordance with the provisions of this Section. Upon the expiration of the

  
 73 

 
period for which the Prepayment Offer remains open (the “Offer Period”), the Company shall deliver to the Trustee for cancellation the Notes or portions thereof which have been properly
tendered to and are to be accepted by the Company. The Trustee or the Paying Agent shall, on the Purchase Date, mail or deliver payment to each tendering Holder in the amount of the purchase price. In the event that the aggregate purchase price of
the Notes delivered by the Company to the Trustee is less than the Offer Amount, the Trustee or the Paying Agent shall deliver the excess to the Company immediately after the expiration of the Offer Period for application in accordance with this
Section. 
 (iii) Holders electing to have a Note purchased shall be required to surrender the Note, with an
appropriate form duly completed, to the Company or its agent at the address specified in the notice at least three Business Days prior to the Purchase Date. Holders shall be entitled to withdraw their election if the Trustee or the Company receives
not later than one Business Day prior to the Purchase Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note which was delivered for purchase by the Holder and a statement
that such Holder is withdrawing his election to have such Note purchased. If at the expiration of the Offer Period the aggregate principal amount of Notes surrendered by Holders exceeds the Offer Amount, the Company shall select the Notes to be
purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000, or integral multiples of $1,000 in excess thereof, shall be purchased). Holders whose Notes are purchased
only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered. 
 (iv) At the time the Company delivers Notes to the Trustee which are to be accepted for purchase, the Company shall also deliver an Officers’ Certificate stating that such Notes are to be accepted by
the Company pursuant to and in accordance with the terms of this Section 9.17. A Note shall be deemed to have been accepted for purchase at the time the Trustee or the Paying Agent mails or delivers payment therefor to the surrendering Holder.

 (d) The Company shall comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any
other securities laws or regulations thereunder to the extent such laws and regulations are applicable in connection with the purchase of Notes as described above. To the extent that the provisions of any securities laws or regulations conflict with
the provisions relating to the Prepayment Offer, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described above by virtue thereof. 

Section 9.18 Limitation on Transactions with Affiliates. 

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into or suffer to
exist any transaction or series of related transactions (including, without limitation, the sale, purchase, exchange or lease of Property or the rendering of any services) with, or for the benefit of, any Affiliate of the Company (other than the
Company or a Wholly Owned Restricted Subsidiary) (each, an “Affiliate Transaction”), unless: 

  
 74 

 (1) such transaction or series of related transactions is on terms that are
no less favorable to the Company or such Restricted Subsidiary, as the case may be, than would be available in a comparable transaction in arm’s-length dealings with an unrelated third party; and 

(2) the Company delivers to the Trustee: 

(a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate
consideration in excess of $10,000,000 but no greater than $25,000,000, an Officers’ Certificate certifying that such Affiliate Transaction or series of Affiliate Transactions complies with this Section 9.18; and 

(b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate
consideration in excess of $25,000,000, an Officers’ Certificate certifying that such Affiliate Transaction or series of Affiliate Transactions complies with this Section 9.18 and that such Affiliate Transaction or series of Affiliate
Transactions has been approved by a majority of the Disinterested Directors of Comstock. 
 (b) The following items will not be
deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 9.18(a): 
 (1) loans or advances to officers, directors and employees of the Company or any Restricted Subsidiary made in the ordinary course of business in an aggregate amount not to exceed $1,000,000 outstanding
at any one time; 
 (2) indemnities of officers, directors, employees and other agents of the Company or any
Restricted Subsidiary permitted by corporate charter or other organizational document, bylaw or statutory provisions; 
 (3) the payment of reasonable and customary fees to directors of the Company or any of its Restricted Subsidiaries who are not employees of the Company or any Affiliate, 

(4) the Company’s employee compensation and other benefit arrangements; 

(5) transactions exclusively between or among the Company and any of the Restricted Subsidiaries or exclusively between or
among such Restricted Subsidiaries, provided such transactions are not otherwise prohibited by this Indenture; and 
 (6) any Restricted Payment permitted to be paid pursuant Section 9.10. 

Section 9.19 Limitation on Dividends and Other Payment Restrictions Affecting Restricted Subsidiaries. 

The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create or suffer to exist or allow to
become effective any consensual encumbrance or restriction of any kind on the ability of any Restricted Subsidiary: (a) to pay dividends, in cash or 

  
 75 

 
otherwise, or make any other distributions on or in respect of its Capital Stock, or make payments on any Indebtedness owed, to the Company or any other Restricted Subsidiary, (b) to make
loans or advances to the Company or any other Restricted Subsidiary or (c) to transfer any of its Property to the Company or any other Restricted Subsidiary (any such restrictions being collectively referred to herein as a “Payment
Restriction”). However, the preceding restrictions will not apply to encumbrances or restrictions existing under or by reason of: 
 (1) customary provisions restricting subletting or assignment of any lease governing a leasehold interest of the Company or any Restricted Subsidiary, or customary restrictions in licenses relating
to the Property covered thereby and entered into in the ordinary course of business; 
 (2) any instrument governing
Indebtedness of a Person acquired by the Company or any Restricted Subsidiary at the time of such acquisition, which encumbrance or restriction is not applicable to any other Person, other than the Person, or the Property of the Person, so acquired,
provided that such Indebtedness was not incurred in anticipation of such acquisition; 
 (3) any instrument
governing Indebtedness or Disqualified Capital Stock of a Restricted Subsidiary that is not a Subsidiary Guarantor, provided that (a) such Indebtedness or Disqualified Capital Stock is permitted under Section 9.12 and (b) the
terms and conditions of any Payment Restrictions thereunder are not materially more restrictive than the Payment Restrictions contained in the Bank Credit Agreement and the Indenture as in effect on the Issue Date; 

(4) the Bank Credit Agreement as in effect on the Issue Date or any agreement that amends, modifies, supplements, restates, extends,
renews, refinances or replaces the Bank Credit Agreement, provided that the terms and conditions of any Payment Restrictions thereunder are not materially more restrictive than the Payment Restrictions contained in the Bank Credit Agreement
as in effect on the Issue Date; 
 (5) this Indenture, the Notes and the Subsidiary Guarantees; or 

(6) the indenture governing the Company’s existing
83/
8% Senior Notes due 2017, 73/4% Senior Notes due 2019, and any subsidiary guarantees thereof, in each case as in effect on the Issue Date. 

Section 9.20 Limitation on Sale and Leaseback Transactions. 

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, enter into any Sale/Leaseback Transaction unless
(1) the Company or such Restricted Subsidiary, as the case may be, would be able to incur Indebtedness in an amount equal to the Attributable Indebtedness with respect to such Sale/Leaseback Transaction or (2) the Company or such
Restricted Subsidiary receives proceeds from such Sale/Leaseback Transaction at least equal to the Fair Market Value thereof and such proceeds are applied in the same manner and to the same extent as Net Available Cash and Excess Proceeds from an
Asset Sale. 

  
 76 

 Section 9.21 Covenant Suspension. 

Following any day (a “Suspension Date”) that (a) the Notes have a rating equal to or higher than BBB- (or the equivalent)
by S&P and a rating equal to or higher than Baa3 (or the equivalent) by Moody’s (“Investment Grade Ratings”), (b) follows a date on which the Notes do not have Investment Grade Ratings, and (c) no Default or Event of
Default has occurred and is continuing under this Indenture, the Company and its Restricted Subsidiaries shall not be subject to the covenants described in Sections 7.1(c), 9.10, 9.12, 9.14, 9.17, 9.18 and 9.19 (collectively, the “Suspended
Covenants”). In the event that the Company and its Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of the preceding sentence, and on any subsequent date the Notes fail to have Investment
Grade Ratings, or a Default or Event of Default occurs and is continuing, then immediately after such date (a “Reversion Date”), the Suspended Covenants will again be in effect with respect to future events, unless and until a subsequent
Suspension Date occurs. The period between a Suspension Date and a Reversion Date is referred to in this Indenture as a “Suspension Period.” Notwithstanding that the Suspended Covenants may be reinstated, no Default or Event of Default
will be deemed to have occurred as a result of a failure to comply with the Suspended Covenants during any Suspension Period. Calculations made after the Reversion Date of the amount available to be made as Restricted Payments under
Section 9.10 will be made as though the covenants described under Section 9.10 had been in effect since the Issue Date and throughout the Suspension Period. During any Suspension Period, the Board of Directors of the Company may not
designate any of the Company’s Subsidiaries as Unrestricted Subsidiaries pursuant to this Indenture. The Company shall give the Trustee prompt written notification upon the occurrence of a Suspension Date or a Reversion Date. 

ARTICLE X. 

REDEMPTION OF NOTES 
 Section 10.1 Notice to Trustee. 
 If the Company elects to redeem
Notes pursuant to paragraph 5 of the Notes, it shall notify the Trustee in writing of the redemption date, the principal amount of Notes to be redeemed and that such redemption is being made pursuant to paragraph 5 of the Notes. 

The Company shall give each notice to the Trustee provided for in this Section at least 60 days before the Redemption Date unless
the Trustee consents to a shorter period. Such notice shall be accompanied by an Officers’ Certificate and an Opinion of Counsel from the Company to the effect that such redemption will comply with the conditions herein. Any election to redeem
Notes shall be revocable until the Company gives a notice of redemption pursuant to Section 10.2 to the Holders of Notes to be redeemed. 
 Section 10.2 Selection by Trustee of Notes to Be Redeemed. 
 If less
than all the Notes are to be redeemed, the particular Notes to be redeemed shall be selected not less than 30 days nor more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Notes not previously called for redemption,
pro rata, by lot or by any other method as the Trustee shall deem fair and appropriate (or in the case of notes in global form, the Trustee will select Notes for redemption based on DTC’s method that most nearly approximates a pro rata
selection) and which may provide for the selection for redemption of portions of the principal of Notes; provided, however, that Notes and portions of Notes selected for redemption shall be in amounts of $2,000 or integral multiples of $1,000
in excess of $2,000. 

  
 77 

 The Trustee shall promptly notify the Company in writing of the Notes selected for
redemption and, in the case of any Notes selected for partial redemption, the principal amount thereof to be redeemed. 
 For
all purposes of this Indenture, unless the context otherwise requires, all provisions relating to redemption of Notes shall relate, in the case of any Note redeemed or to be redeemed only in part, to the portion of the principal amount of such Note
which has been or is to be redeemed. 
 Section 10.3 Notice of Redemption. 

Notice of redemption shall be given in the manner provided for in Section 13.5 hereof not less than 30 nor more than 60 days prior
to the Redemption Date, to each Holder of Notes to be redeemed. 
 All notices of redemption shall state: 

(a) the Redemption Date; 
 (b) the Redemption Price; 
 (c) if less than all Outstanding Notes are to be
redeemed, the identification (and, in the case of a partial redemption, the principal amounts) of the particular Notes to be redeemed; 
 (d) that on the Redemption Date the Redemption Price (together with accrued interest, if any, to the Redemption Date payable as provided in Section 10.5 hereof) will become due and payable upon each
such Note, or the portion thereof, to be redeemed, and that, unless the Company shall default in the payment of the Redemption Price and any applicable accrued interest, interest thereon will cease to accrue on and after said date; and 

(e) the place or places where such Notes are to be surrendered for payment of the Redemption Price. 

Notice of redemption of Notes to be redeemed at the election of the Company shall be given by the Company or, at the Company’s
request, by the Trustee in the name and at the expense of the Company. Failure to give such notice by mailing to any Holder of Notes or any defect therein shall not affect the validity of any proceedings for the redemption of other Notes.

 Section 10.4 Deposit of Redemption Price. 

On or before 10:00 a.m., New York City time, on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent
(or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 9.3 hereof) an amount of money sufficient to pay the Redemption Price of, and accrued and unpaid interest on, all the Notes which are to
be redeemed on such Redemption Date. 

  
 78 

 Section 10.5 Notes Payable on Redemption Date. 

Notice of redemption having been given as aforesaid, the Notes so to be redeemed shall, on the Redemption Date, become due and payable at
the Redemption Price therein specified (together with accrued and unpaid interest, if any, to the Redemption Date), and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued and unpaid
interest) such Notes shall cease to bear interest. Upon surrender of any such Note for redemption in accordance with said notice, such Note shall be paid by the Company at the Redemption Price, together with accrued and unpaid interest, if any, to
the Redemption Date. 
 If any Note called for redemption shall not be so paid upon surrender thereof for redemption, the
principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate borne by the Notes. 

Section 10.6 Notes Redeemed in Part. 
 Any Note which is to be redeemed only in part shall be surrendered at the office or agency of the Company maintained for such purpose pursuant to Section 9.2 hereof (with, if the Company or the
Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing), and the Company shall
execute, and the Trustee shall authenticate and deliver to the Holder of such Note without service charge, a new Note or Notes, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for
the unredeemed portion of the principal amount of the Note so surrendered. 
 ARTICLE XI. 

DEFEASANCE AND COVENANT DEFEASANCE 
 Section 11.1 Company’s Option to Effect Defeasance or Covenant Defeasance. 
 The Company may, at its option by Board Resolution, at any time, with respect to the Notes, elect to have either Section 11.2 or Section 11.3 hereof be applied to all Outstanding Notes upon
compliance with the conditions set forth below in this Article XI. 
 Section 11.2 Defeasance and Discharge.

 Upon the Company’s exercise under Section 11.1 hereof of the option applicable to this Section 11.2, the
Company and the Subsidiary Guarantors shall be deemed to have been discharged from their respective obligations with respect to all Outstanding Notes on the date the conditions set forth in Section 11.4 hereof are satisfied (hereinafter,
“legal defeasance”). For this purpose, such legal defeasance means that the Company and the Subsidiary Guarantors shall be deemed (i) to have paid and discharged their respective obligations under the Outstanding Notes; provided,
however, that the Notes shall continue to be deemed to be “Outstanding” for purposes of Section 11.5 hereof and the other Sections of this Indenture referred to in clauses (a) and (b) below, and (ii) to have
satisfied all their other obligations with respect to such Notes and this Indenture (and the Trustee, at the expense and direction of the Company, shall execute proper 

  
 79 

 
instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of Outstanding Notes to
receive, solely from the trust fund described in Section 11.4 hereof and as more fully set forth in such Section, payments in respect of the principal of (and premium if any, on) and interest on such Notes when such payments are due (or at such
time as the Notes would be subject to redemption at the option of the Company in accordance with this Indenture), (b) the respective obligations of the Company and the Subsidiary Guarantors under Sections 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9,
5.8, 5.14, 9.2, 12.1 (to the extent it relates to the foregoing Sections and this Article XI), 12.4 and 12.5 hereof and the Appendix, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder, and (d) the obligations
of the Company and the Subsidiary Guarantors under this Article XI. Subject to compliance with this Article XI, the Company may exercise its option under this Section 11.2 notwithstanding the prior exercise of its option under Section 11.3
hereof with respect to the Notes. 
 Section 11.3 Covenant Defeasance. 

Upon the Company’s exercise under Section 11.1 hereof of the option applicable to this Section 11.3, the Company and each
Subsidiary Guarantor shall be released from their respective obligations under any covenant contained in Section 9.5 hereof, in Sections 9.8 through 9.20 hereof and in clauses (c) and (e) of Section 7.1 hereof with respect to the
Outstanding Notes on and after the date the conditions set forth below are satisfied (hereinafter, “covenant defeasance”), and the Notes shall thereafter be deemed not to be “Outstanding” for the purposes of any direction,
waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant
defeasance means that, with respect to the Outstanding Notes, the Company and each Subsidiary Guarantor may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether
directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a
Default or an Event of Default under Section 5.1(c), 5.1(d) or 5.1(e) hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. 

Section 11.4 Conditions to Defeasance or Covenant Defeasance. 

The following shall be the conditions to application of either Section 11.2 or Section 11.3 hereof to the Outstanding Notes:

 (a) The Company or any Subsidiary Guarantor shall irrevocably have deposited or caused to be deposited with the Trustee (or
another trustee satisfying the requirements of Section 6.7 hereof who shall agree to comply with the provisions of this Article XI applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged
as security for, and dedicated solely to, the benefit of the Holders of such Notes, (a) cash in United States dollars in an amount, or (b) U.S. Government Obligations which through the scheduled payment of principal and interest in respect
thereof in accordance with their terms will provide, not later than one day before the due date of any payment, money in an amount, or (c) a combination thereof, sufficient, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the Trustee, to pay 

  
 80 

 
and discharge, and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge, the principal of (and premium, if any, on) and interest on the Outstanding Notes on
the Stated Maturity thereof (or Redemption Date, if applicable), provided that the Trustee shall have been irrevocably instructed in writing by the Company to apply such money or the proceeds of such U.S. Government Obligations to said
payments with respect to the Notes. Before such a deposit, the Company may give to the Trustee, in accordance with Section 10.1 hereof, a notice of its election to redeem all of the Outstanding Notes at a future date in accordance with Article
X hereof, which notice shall be irrevocable. Such irrevocable redemption notice, if given, shall be given effect in applying the foregoing. For this purpose, “U.S. Government Obligations” means securities that are (x) direct
obligations of the United States of America for the timely payment of which its full faith and credit is pledged or (y) obligations of a Person controlled or supervised by and acting as an agency or instrumentality of the United States of
America the timely payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either case, are not callable or redeemable at the option of the issuer thereof, and shall also
include a depository receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act), as custodian with respect to any such U.S. Government Obligation or a specific payment of principal of or interest on any such U.S. Government
Obligation held by such custodian for the account of the holder of such depository receipt, provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such
depository receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the specific payment of principal of or interest on the U.S. Government Obligation evidenced by such depository receipt. 

(b) No Default or Event of Default with respect to the Notes shall have occurred and be continuing on the date of such deposit or,
insofar as Sections 5.1(i) and 5.1(j) are concerned, at any time during the period ending on the 91st day after the date of such deposit. 
 (c) Such legal defeasance or covenant defeasance shall not cause the Trustee to have a conflicting interest under this Indenture or the Trust Indenture Act with respect to any securities of the Company or
any Subsidiary Guarantor. 
 (d) Such legal defeasance or covenant defeasance shall not result in a breach or violation of, or
constitute a default under, any other material agreement or instrument to which the Company or any Subsidiary Guarantor is a party or by which it is bound, as evidenced to the Trustee in an Officers’ Certificate delivered to the Trustee
concurrently with such deposit. 
 (e) In the case of an election under Section 11.2 hereof, the Company shall have
delivered to the Trustee an Opinion of Counsel stating that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (ii) since the date of this Indenture there has been a change in the
applicable federal income tax laws, in either case providing that the Holders of the Outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such legal defeasance and will be subject to federal income
tax on the same amounts, in the same manner and at the same times as would have been the case if such legal defeasance had not occurred (it being understood that (x) such Opinion of Counsel shall also state that such ruling or applicable law is
consistent with the conclusions reached in such Opinion of Counsel and (y) the Trustee shall be under no obligation to investigate the basis or correctness of such ruling). 

  
 81 

 (f) In the case of an election under Section 11.3 hereof, the Company shall have
delivered to the Trustee an Opinion of Counsel to the effect that the Holders of the Outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such covenant defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred. 
 (g) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, which, taken together, state that all conditions precedent provided for relating to either the
legal defeasance under Section 11.2 hereof or the covenant defeasance under Section 11.3 (as the case may be) have been complied with. 
 Section 11.5 Deposited Money and U.S. Government Obligations to Be Held in Trust; Other Miscellaneous Provisions. 
 Subject to the provisions of the last paragraph of Section 9.3 hereof, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying
trustee; collectively for purposes of this Section 11.5, the “Trustee”) pursuant to Section 11.4 hereof in respect of the Outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of
such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in
respect of principal (and premium, if any) and interest, but such money need not be segregated from other funds except to the extent required by law. 
 The Company shall pay and indemnify the Trustee against all taxes, fees or other charges imposed on or assessed against the U.S. Governmental Obligations deposited pursuant to Section 11.4 hereof or
the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the Outstanding Notes. 
 Anything in this Article XI to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or U.S. Government Obligations held by it as
provided in Section 11.4 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect an equivalent legal defeasance or covenant defeasance, as applicable, in accordance with this Article. 
 Section 11.6 Reinstatement. 
 If the Trustee or any Paying Agent is
unable to apply any money in accordance with Section 11.5 hereof by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the
Subsidiary Guarantors’ obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.2 or 11.3 hereof, as the case may be, until such time as the Trustee or Paying
Agent is permitted to apply all such money in accordance with Section 11.5 hereof; provided, however, that if the Company or any Subsidiary Guarantor makes any payment of principal of (or premium, if any, on) or interest on any Note
following the reinstatement of its obligations, the Company or such Subsidiary Guarantor shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent. 

  
 82 

 ARTICLE XII. 
 SUBSIDIARY GUARANTEES 
 Section 12.1 Unconditional Guarantee.

 Each Subsidiary Guarantor hereby unconditionally, jointly and severally, guarantees (each such guarantee being referred to
herein as this “Subsidiary Guarantee,” with all such guarantees being referred to herein as the “Subsidiary Guarantees”) to each Holder of Notes authenticated and delivered by the Trustee and to the Trustee and its successors and
assigns, the full and prompt performance of the Company’s obligations under the Indenture and the Notes and that: 
 (a) the
principal of (and premium, if any, on) and interest on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, to
the extent lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 

(b) in case of any extension of time of payment or renewal of any Notes or of any such other obligations, the same will be promptly paid
in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise; 
 subject, however, in the case of clauses (a) and (b) above, to the limitations set forth in Section 12.4 hereof. 
 Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Subsidiary Guarantors will be jointly and severally obligated to pay the same immediately.
Each Subsidiary Guarantor hereby agrees that its obligations hereunder shall, to the extent permitted by law, be unconditional, irrespective of the validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to
enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor. Each Subsidiary Guarantor hereby waives, to the extent permitted by law, diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or
bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever, and covenants that its Subsidiary Guarantee will not be discharged except by complete performance of the obligations
contained in the Notes, the Indenture and in this Subsidiary Guarantee. If any Holder or the Trustee is required by any court or otherwise to return to the Company, any Subsidiary Guarantor, or any custodian, trustee, liquidator or other similar
official acting in relation to the Company or any Subsidiary Guarantor, any amount paid by the Company or any Subsidiary Guarantor to the 

  
 83 

 
Trustee or such Holder, this Subsidiary Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Subsidiary Guarantor agrees it shall not be entitled to
enforce any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Subsidiary Guarantor further agrees that, as between each Subsidiary
Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article V hereof for the purposes of this Subsidiary Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article V hereof, such
obligations (whether or not due and payable) shall forthwith become due and payable by each Subsidiary Guarantor for the purpose of this Subsidiary Guarantee. 
 Section 12.2 Subsidiary Guarantors May Consolidate, etc., on Certain Terms. 
 (a) Except as set forth in Article VII hereof, nothing contained in this Indenture or in any of the Notes shall prevent any consolidation or merger of a Subsidiary Guarantor with or into the Company or
another Subsidiary Guarantor or shall prevent any sale, conveyance or other disposition of all or substantially all the Properties of a Subsidiary Guarantor to the Company or another Subsidiary Guarantor. 

(b) Except as set forth in Article VII hereof, nothing contained in this Indenture or in any of the Notes shall prevent any consolidation
or merger of a Subsidiary Guarantor with or into a Person other than the Company or another Subsidiary Guarantor (whether or not Affiliated with such Subsidiary Guarantor), or successive consolidations or mergers in which a Subsidiary Guarantor or
its successor or successors shall be a party or parties, or shall prevent any sale, conveyance or other disposition of all or substantially all the Properties of a Subsidiary Guarantor to a Person other than the Company or another Subsidiary
Guarantor (whether or not Affiliated with such Subsidiary Guarantor) authorized to acquire and operate the same; provided, however, that (i) immediately after such transaction, and giving effect thereto, no Default or Event of Default
shall have occurred as a result of such transaction and be continuing, (ii) such transaction shall not violate any of the covenants of Sections 9.1 through 9.20 hereof, and (iii) upon any such consolidation, merger, sale, conveyance or
other disposition, such Subsidiary Guarantor’s Subsidiary Guarantee set forth in this Article XII, and the due and punctual performance and observance of all of the covenants and conditions of this Indenture to be performed by such Subsidiary
Guarantor, shall be expressly assumed, by supplemental indenture satisfactory in form to the Trustee, executed and delivered to the Trustee, by such Person formed by such consolidation or into which such Subsidiary Guarantor shall have merged (if
other than such Subsidiary Guarantor), or by the Person that shall have acquired such Property (except to the extent the following Section 12.3 would result in the release of such Subsidiary Guarantee, in which case such surviving Person or
transferee of such Property shall not have to execute any such supplemental indenture and shall not have to assume such Subsidiary Guarantor’s Subsidiary Guarantee). In the case of any such consolidation, merger, sale, conveyance or other
disposition and upon the assumption by the successor Person, by supplemental indenture executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual performance and observance of all of the covenants and
conditions of this Indenture to be performed by the applicable Subsidiary Guarantor, such successor Person shall succeed to and be substituted for such Subsidiary Guarantor with the same effect as if it had been named herein as the initial
Subsidiary Guarantor. 

  
 84 

 Section 12.3 Release of Subsidiary Guarantors. 

Upon the sale or disposition (by merger or otherwise) of a Subsidiary Guarantor (or all or substantially all of its Properties) to a
Person other than the Company or another Subsidiary Guarantor and pursuant to a transaction that is otherwise in compliance with the terms of this Indenture, including but not limited to the provisions of Section 12.2 hereof or pursuant to
Article VII hereof, such Subsidiary Guarantor shall be deemed released from its Subsidiary Guarantee and all related obligations under this Indenture; provided, however, that any such release shall occur only to the extent that all
obligations of such Subsidiary Guarantor under all of its guarantees of, and under all of its pledges of assets or other security interests which secure, other Indebtedness of the Company or any other Restricted Subsidiary shall also be released
upon such sale or other disposition. The Trustee shall deliver an appropriate instrument evidencing such release upon receipt of a Company Request accompanied by an Officers’ Certificate and an Opinion of Counsel certifying that such sale or
other disposition was made by the Company in accordance with the provisions of this Indenture. In addition, in the event that any Subsidiary Guarantor ceases to guarantee payment of, or in any other manner to remain liable (whether directly or
indirectly) with respect to, any and all other Indebtedness of the Company or any other Restricted Subsidiary of the Company, including, without limitation, Indebtedness under the Bank Credit Agreement, such Subsidiary Guarantor shall also be
released from its Subsidiary Guarantee and the related obligations under this Indenture for so long as it remains not liable with respect to all such other Indebtedness. The Trustee shall deliver an appropriate instrument evidencing such release
upon receipt of a Company Request accompanied by an Officers’ Certificate and an Opinion of Counsel certifying that such Subsidiary Guarantor has ceased to guarantee or otherwise be liable with respect to such other Indebtedness of the Company
and the other Restricted Subsidiaries. Each Subsidiary Guarantor that is designated as an Unrestricted Subsidiary in accordance with the provisions of this Indenture shall be released from its Subsidiary Guarantee and all related obligations under
this Indenture for so long as it remains an Unrestricted Subsidiary. The Trustee shall deliver an appropriate instrument evidencing such release upon its receipt of the Board Resolution designating such Unrestricted Subsidiary. Any Subsidiary
Guarantor not released in accordance with this Section 12.3 shall remain liable for the full amount of principal of (and premium, if any, on) and interest on the Notes as provided in this Article XII. 

Section 12.4 Limitation of Subsidiary Guarantors’ Liability. 

Each Subsidiary Guarantor, and by its acceptance hereof each Holder, hereby confirm that it is the intention of all such parties that the
guarantee by such Subsidiary Guarantor pursuant to its Subsidiary Guarantee not constitute a fraudulent transfer or conveyance for purposes of the Federal Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or
any similar federal or state law. To effectuate the foregoing intention, the Holders and each Subsidiary Guarantor hereby irrevocably agree that the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee shall be limited to the
maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of
the obligations of such other Subsidiary 

  
 85 

 
Guarantor under its Subsidiary Guarantee or pursuant to Section 12.5 hereof, result in the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee not constituting such a
fraudulent conveyance or fraudulent transfer. This Section 12.4 is for the benefit of the creditors of each Subsidiary Guarantor. 
 Section 12.5 Contribution. 
 In order to provide for just and
equitable contribution among the Subsidiary Guarantors, the Subsidiary Guarantors agree, inter se, that in the event any payment or distribution is made by any Subsidiary Guarantor (a “Funding Guarantor”) under its Subsidiary Guarantee,
such Funding Guarantor shall be entitled to a contribution from each other Subsidiary Guarantor (if any) in a pro rata amount based on the Adjusted Net Assets of each Subsidiary Guarantor (including the Funding Guarantor) for all payments, damages
and expenses incurred by that Funding Guarantor in discharging the Company’s obligations with respect to the Notes or any other Subsidiary Guarantor’s obligations with respect to its Subsidiary Guarantee. 

Section 12.6 Severability. 
 In case any provision of this Subsidiary Guarantee shall be invalid, illegal or unenforceable, that portion of such provision that is not invalid, illegal or unenforceable shall remain in effect, and the
validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 

ARTICLE XIII. 
 MISCELLANEOUS 
 Section 13.1 Compliance Certificates and
Opinions. 
 Upon any application or request by the Company or any Subsidiary Guarantor to the Trustee to take any action
under any provision of this Supplemental Indenture, the Company or such Subsidiary Guarantor, as the case may be, shall furnish to the Trustee such certificates and opinions as may be required under the Trust Indenture Act or this Supplemental
Indenture. Each such certificate and each such legal opinion shall be in the form of an Officers’ Certificate or an Opinion of Counsel, as applicable, and shall comply with the requirements of this Supplemental Indenture. 

Every certificate or opinion with respect to compliance with a condition or covenant provided for in this Supplemental Indenture shall
include: 
 (1) a statement that each Person signing such certificate or opinion has read such covenant or condition and the
definitions herein relating thereto; 
 (2) a brief statement as to the nature and scope of the examination or investigation upon
which the statements or opinions contained in such certificate or opinion are based; 

  
 86 

 (3) a statement that, in the opinion of each such Person, such Person has made such
examination or investigation as is necessary to enable him to express an informed opinion as to whether or not such covenant or condition has been complied with; and 
 (4) a statement as to whether, in the opinion of each such Person, such condition or covenant has been complied with. 
 The certificates and opinions provided pursuant to this Section 13.1 and the statements required by this Section 13.1 shall be satisfactory to the Trustee and comply in all respects with TIA
Sections 314(c) and (e). 
 Section 13.2 Form of Documents Delivered to Trustee. 

In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary
that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more
other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents. 
 Any certificate or opinion of an officer may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the
exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such Opinion of Counsel may be based, insofar as it relates to
factual matters, upon an officers’ certificate, unless such counsel knows, or in the exercise of reasonable care should know, that the certificate with respect to such matters is erroneous. 

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or
other instruments under this Supplemental Indenture, they may, but need not, be consolidated and form one instrument. 

Section 13.3 Acts of Holders. 
 (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Supplemental Indenture to be given or taken by Holders may be embodied in and evidenced by one
or more instruments of substantially similar tenor signed by such Holders in person or by agents duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments
are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders
signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Supplemental Indenture and conclusive in favor of the Trustee and the Company, if
made in the manner provided in this Section. 

  
 87 

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

(d) If the Company shall solicit from the Holders of Notes any request, demand, authorization, direction, notice, consent, waiver or other
Act, the Company may, at its option, by or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the
Company shall have no obligation to do so. Notwithstanding TIA Section 316(c), such record date shall be the record date specified in or pursuant to such Board Resolution, which shall be a date not earlier than the date 30 days prior to the
first solicitation of Holders generally in connection therewith and not later than the date such solicitation is completed. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be
given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of Outstanding Notes have
authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Notes shall be computed as of such record date, provided that no such authorization,
agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Supplemental Indenture not later than eleven months after the record date. 

(e) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of Notes shall bind every future
Holder of the Notes and the Holder of Notes issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon,
whether or not notation of such action is made upon such Notes. 
 Section 13.4 Notices, etc. to Trustee, Company and
Subsidiary Guarantors. 
 Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other
document provided or permitted by this Indenture to be made upon, given or furnished to or filed with, 
 (1) the
Trustee by any Holder, the Company or any Subsidiary Guarantor shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing (in the English language) and delivered in person or mailed by certified or registered mail
(return receipt requested) to the Trustee at its Corporate Trust Office; or 
 (2) the Company or any Subsidiary
Guarantor by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing (in the English language) and delivered in person or mailed by

  
 88 

 
certified or registered mail (return receipt requested) to the Company or such Subsidiary Guarantor, as applicable, addressed to it at the Company’s offices located at 5300 Town and Country
Blvd., Suite 500, Frisco, Texas, 75034, Attention: Chief Financial Officer, or at any other address otherwise furnished in writing to the Trustee by the Company. 
 Section 13.5 Notice to Holders; Waiver. 
 Where this Supplemental
Indenture provides for notice of any event to Holders by the Company or the Trustee, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing (in the English language) and mailed, first-class postage
prepaid, to each Holder affected by such event, at his address as it appears in the Note Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders
is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Any notice mailed to a Holder in the manner herein
prescribed shall be conclusively deemed to have been received by such Holder, whether or not such Holder actually receives such notice. Where this Supplemental Indenture provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the
validity of any action taken in reliance upon such waiver. 
 In case by reason of the suspension of or irregularities in
regular mail service or by reason of any other cause, it shall be impracticable to mail notice of any event to Holders when such notice is required to be given pursuant to any provision of this Supplemental Indenture, then any manner of giving such
notice as shall be satisfactory to the Trustee shall be deemed to be a sufficient giving of such notice for every purpose hereunder. 
 The Trustee may rely upon and comply with instructions or directions sent via unsecured facsimile or email transmission and the Trustee shall not be liable for any loss, liability or expense of any kind
incurred by the Company or the Holders due to the Trustee’s reliance upon and compliance with instructions or directions given by unsecured facsimile or email transmission; provided, however, that such losses have not arisen from the
negligence or willful misconduct of the Trustee, it being understood that the failure of the Trustee to verify or confirm that the person providing the instructions or directions, is, in fact, an authorized person does not constitute negligence or
willful misconduct. 
 Section 13.6 Effect of Headings and Table of Contents. 

The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

 Section 13.7 Successors and Assigns. 
 All covenants and agreements in this Supplemental Indenture by the Company and the Subsidiary Guarantors shall bind their respective successors and assigns, whether so expressed or not. All agreements of
the Trustee in this Supplemental Indenture shall bind its successor. 

  
 89 

 Section 13.8 Severability. 

In case any provision in this Supplemental Indenture or in the Notes or the Subsidiary Guarantees shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby, and a Holder shall have no claim therefor against any party hereto. 

Section 13.9 Benefits of Supplemental Indenture. 
 Nothing in this Supplemental Indenture or in the Notes, express or implied, shall give to any Person (other than the parties hereto, any Paying Agent, any Registrar and their successors hereunder, the
Holders and, to the extent set forth in Section 12.4 hereof, creditors of Subsidiary Guarantors) any benefit or any legal or equitable right, remedy or claim under this Supplemental Indenture. 

Section 13.10 Governing Law; Trust Indenture Act Controls. 

(a) THIS SUPPLEMENTAL INDENTURE, THE SUBSIDIARY GUARANTEES AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE
WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY. THE COMPANY AND EACH SUBSIDIARY
GUARANTOR IRREVOCABLY SUBMIT TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR NEW YORK STATE COURT SITTING IN THE BOROUGH OF MANHATTAN, THE CITY OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS SUPPLEMENTAL
INDENTURE, THE NOTES OR THE SUBSIDIARY GUARANTEES, AND THE COMPANY AND EACH SUBSIDIARY GUARANTOR IRREVOCABLY AGREE THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED BY ANY SUCH COURT. 

(b) This Supplemental Indenture is subject to the provisions of the Trust Indenture Act that are required to be part of this Indenture and
shall, to the extent applicable, be governed by such provisions. If and to the extent that any provision of this Supplemental Indenture limits, qualifies or conflicts with the duties imposed by operation of Section 318(c) of the Trust Indenture
Act, or conflicts with any provision (an “incorporated provision”) required by or deemed to be included in this Indenture by operation of such Trust Indenture Act section, such imposed duties or incorporated provision shall control.

 Section 13.11 Legal Holidays. 
 In any case where any Interest Payment Date, Redemption Date, or Stated Maturity or Maturity of the Notes shall not be a Business Day, then (notwithstanding any other provision of this Indenture or of the
Notes or the Subsidiary Guarantee) payment of interest or principal (and premium, if any) need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the Interest Payment Date,
Redemption Date or at the Stated Maturity or Maturity; provided, however, that no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date, Stated Maturity or Maturity, as the case may be. 

  
 90 

 Section 13.12 No Personal Liability of Directors, Officers, Employees and
Stockholders. 
 No director, officer, employee, incorporator, stockholder, member, partner or trustee of the Company or any
Subsidiary Guarantor, as such, shall have any liability for any obligations of the Company or any Subsidiary Guarantor under the notes, the Indenture or the Subsidiary Guarantees or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. 

Section 13.13 Holder Communications. 
 Holders may communicate pursuant to Section 312(b) of the TIA with other Holders with respect to their rights under this Indenture or the Notes. Every Holder of Notes, by receiving and holding the
same, agrees with the Company, the Subsidiary Guarantors, the Registrar and the Trustee that none of the Company, the Subsidiary Guarantors, the Registrar or the Trustee, or any agent of any of them, shall be held accountable by reason of the
disclosure of any information as to the names and addresses of the Holders in accordance with TIA Section 312, regardless of the source from which such information was derived, that each of such Persons shall have the protection of TIA
Section 312(c) and that the Trustee shall not be held accountable by reason of mailing any material pursuant to a request made under TIA Section 312(b). 
 Section 13.14 Duplicate Originals. 
 The parties may sign any number
of copies or counterparts of this Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. 
 Section 13.15 No Adverse Interpretation of Other Agreements. 
 This
Supplemental Indenture may not be used to interpret another indenture, loan or debt agreement of the Company or any of its Subsidiaries. Any such indenture, loan or debt agreement may not be used to interpret this Supplemental Indenture. 

Section 13.16 Force Majeure. 
 In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its
control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities,
communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under
the circumstances. 

  
 91 

 Section 13.17 Waiver of Jury Trial. 

EACH OF THE COMPANY, THE SUBSIDIARY GUARANTORS AND THE TRUSTEE AND HOLDERS OF NOTES BY ACCEPTING A BENEFICIAL INTEREST IN THE NOTES HEREBY
IRREVOCABLE WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS SUPPLEMENTAL INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED HEREBY.

 [FORM OF REVERSE SIDE OF NOTE] 

9 1/2% Senior Note due 2020 
  

	1.	Interest. 

 Comstock
Resources, Inc., a Nevada corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Note at the
rate per annum shown above. The Company will pay interest semiannually on June 15 and December 15 of each year. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid,
from the date of original issuance thereof. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The Company shall pay interest on overdue principal at the rate borne by the Notes plus 1% per annum, and it shall pay
interest on overdue installments of interest at the same rate to the extent lawful. 
  

	2.	Method of Payment. 

 The
Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered holders of Notes at the close of business on the June 1 or December 1 next preceding the interest payment date even if Notes are canceled
after the record date and on or before the interest payment date. Holders must surrender Notes to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States of America that at the time of
payment is legal tender for payment of public and private debts. Payments in respect of the Notes represented by a Global Note (including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts
specified by The Depository Trust Company. The Company will make all payments in respect of a certificated Note (including principal, premium and interest), by mailing a check to the registered address of each Holder thereof; provided,
however, that payments on the Notes may also be made, in the case of a Holder of at least $500,000 aggregate principal amount of Notes, by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such
Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the
Trustee may accept in its discretion). 
  

	3.	Paying Agent and Registrar. 

 Initially, The Bank of New York Mellon Trust Company, N.A. (the “Trustee”) will act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent, Registrar or co-registrar
without notice. The Company may act as Paying Agent, Registrar or co-registrar. 

  
 Form of
Reverse Side of Security, Page 1 

	4.	Indenture. 

 The Company
issued the Notes under an Indenture dated as of October 9, 2009 between the Company, the Subsidiary Guarantors and the Trustee (the “Original Indenture”), as supplemented by a Fourth Supplemental Indenture dated as of even date
therewith (the “Supplemental Indenture”, and the Original Indenture as supplemented thereby, the “Indenture”). The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act of 1939, as amended (15 U.S.C. Sections 77aaa-77bbbb) as in effect on the date of the Indenture (the “TIA”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The
Notes are subject to all such terms, and the Holders are referred to the Indenture and the TIA for a statement of those terms. 

The Notes are general unsecured obligations of the Company with no limit as to the aggregate principal amount at any one time outstanding
(subject to Section 9.12 of the Indenture). The Notes issued on the Issue Date and any Additional Notes are treated as a single class of securities for all purposes of the Indenture. The Indenture imposes certain limitations on the ability of
the Company and its Restricted Subsidiaries to, among other things, make certain Investments and other Restricted Payments, pay dividends and other distributions, incur Indebtedness, enter into consensual restrictions upon the payment of certain
dividends and distributions by such Restricted Subsidiaries, issue or sell shares of certain capital stock of such Restricted Subsidiaries, enter into or permit certain transactions with Affiliates, create or incur Liens and make Asset Sales. The
Indenture also imposes limitations on the ability of the Company or any Subsidiary Guarantor to consolidate or merge with or into any other Person or convey, transfer or lease all or substantially all of the Property of the Company or any Subsidiary
Guarantor. 
 To guarantee the due and punctual payment of the principal and interest on the Notes and all other amounts payable
by the Company under the Indenture and the Notes when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Notes and the Indenture, the Subsidiary Guarantors will unconditionally
guarantee the Obligations on a joint and several basis pursuant to the terms of the Indenture. 
  

	5.	Optional Redemption. 

 The
Notes are subject to redemption, at the option of the Company, in whole or in part, at any time on or after June 15, 2016 at the following Redemption Prices (expressed as percentages of principal amount) set forth below if redeemed during the
12-month period beginning June 15 of the years indicated below: 
  

					
	Year	  	Redemption Price	 
	 2016
	  	 	104.750	% 
	 2017
	  	 	102.375	% 
	 2018 and thereafter
	  	 	100.000	% 

 together in the case of any such redemption with accrued and unpaid interest, if any, to the Redemption Date (subject to
the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Redemption Date), all as provided in the Indenture. 

  
 Form of
Reverse Side of Security, Page 2 

 Notwithstanding the foregoing, prior to June 15, 2015, the Company may redeem, at any
time or from time to time, up to 35% of the aggregate principal amount of Notes issued on the Issue Date, at a redemption price of 109.50% of the principal amount thereof, plus accrued and unpaid interest, if any, to the Redemption Date (subject to
the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Redemption Date), with the Net Cash Proceeds of one or more Public Equity Offerings, provided that at
least 65% of the aggregate principal amount of Notes issued on the Issue Date remains outstanding immediately after such redemption (excluding Notes held by the Company and its Subsidiaries) and that such redemption occurs within 120 days following
the closing of any such Public Equity Offering. 
  

	6.	Sinking Fund. 

 The Notes
are not subject to any sinking fund. 
  

	7.	Notice of Redemption. 

Notice of redemption will be sent at least 30 days but not more than 60 days before the redemption date to each Holder of Notes to be
redeemed at his or her registered address. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000 in excess of $2,000. If money sufficient to pay the redemption price of and accrued interest on all
Notes (or portions thereof) to be redeemed on the redemption date is deposited with the Paying Agent on or before the redemption date and certain other conditions are satisfied, on and after such date interest ceases to accrue on such Notes (or such
portions thereof) called for redemption. 
  

	8.	Repurchase of Notes at the Option of Holders upon Change of Control. 

 Upon the occurrence of a Change of Control, any Holder of Notes will have the right, subject to certain conditions specified in the Indenture, to cause the Company to repurchase all or any part of the
Notes of such Holder at a purchase price equal to 101% of the principal amount of the Notes to be repurchased plus accrued and unpaid interest, if any, to the date of purchase as provided in, and subject to the terms of, the Indenture. 

 

	9.	Denominations; Transfer; Exchange. 

 The Notes are in registered form without coupons in denominations of $2,000 and whole multiples of $1,000 in excess of $2,000. A Holder may transfer or exchange Notes in accordance with the Indenture.
Upon any transfer or exchange, the Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes required by law or permitted by the Indenture. 

 

	10.	Persons Deemed Owners. 

The registered Holder of this Note may be treated as the owner of it for all purposes.

	11.	Unclaimed Money. 

 If
money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its written request unless an abandoned property law designates another Person. After any such
payment, Holders entitled to the money must look only to the Company and not to the Trustee for payment. 
  

	12.	Discharge and Defeasance. 

Subject to certain conditions, the Company at any time may terminate some of or all its obligations under the Notes and the Indenture if
the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Notes to redemption or maturity, as the case may be. 

 

	13.	Amendment, Waiver. 

 The
Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the Subsidiary Guarantors and the rights of the Holders under the Indenture at any time by
the Company, the Subsidiary Guarantors and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Notes at the time Outstanding. The Indenture also contains provisions permitting the Holders of specified
percentages in aggregate principal amount of the Notes at the time Outstanding, on behalf of the Holders of all the Notes, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and
their consequences. Any such consent or waiver by or on behalf of the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Note. Without the consent of any Holder, the Company, the Subsidiary Guarantors and the Trustee may amend or supplement the Indenture or the Notes
to cure any ambiguity, defect or inconsistency, to qualify or maintain the qualification of the Indenture under the TIA, to add or release any Subsidiary Guarantor pursuant to the Indenture and to make certain other specified changes and other
changes that do not adversely affect the interests of any Holder. 
  

	14.	Defaults and Remedies. 

As set forth in the Indenture, an Event of Default is generally (i) failure to pay principal upon maturity, redemption or otherwise
(including pursuant to a Change of Control Offer or a Prepayment Offer); (ii) default for 30 days in payment of interest on any of the Notes; (iii) default in the performance of agreements relating to mergers, consolidations and sales of
all or substantially all assets or the failure to make or consummate a Change of Control Offer or a Prepayment Offer; (iv) failure for 90 days after notice to comply with Section 9.9 of the Indenture; (v) failure for 60 days after
notice to comply with any other covenants in the Indenture, any Subsidiary Guarantee or the Notes; (vi) certain payment defaults under, and the acceleration prior to the maturity of, certain Indebtedness of the Company or any Restricted
Subsidiary in an aggregate principal amount in excess of $50,000,000; (vi) the failure of any Subsidiary Guarantee to be in full force and effect (except as permitted by the Indenture); 

  
 Form of
Reverse Side of Security, Page 4 

 
(vii) certain final judgments or orders against the Company or any Restricted Subsidiary in an aggregate amount of more than $50,000,000 (net of any amounts covered by insurance with a
reputable and creditworthy insurance company that has not disclaimed liability) which remain unsatisfied and either become subject to commencement of enforcement proceedings or remain unstayed for a period of 60 days; and (viii) certain events
of bankruptcy, insolvency or reorganization of the Company or any Restricted Subsidiary. If any Event of Default occurs and is continuing, the Trustee or the holders of at least 25% in aggregate principal amount of the Outstanding Notes may declare
the principal amount of all the Notes to be due and payable immediately, except that (i) in the case of an Event of Default arising from certain events of bankruptcy, insolvency or reorganization of the Company or any Restricted Subsidiary, the
principal amount of the Notes will become due and payable immediately without further action or notice, and (ii) in the case of an Event of Default which relates to certain payment defaults or the acceleration with respect to certain
Indebtedness, any such Event of Default and any consequential acceleration of the Notes will be automatically rescinded if any such Indebtedness is repaid or if the default relating to such Indebtedness is cured or waived, and if the holders thereof
have accelerated such Indebtedness, such holders have rescinded their declaration of acceleration. No Holder may pursue any remedy under the Indenture unless the Trustee shall have failed to act after notice from such Holder of an Event of Default
and written request by Holders of at least 25% in aggregate principal amount of the Outstanding Notes to institute proceedings in respect of such Event of Default, and the offer to the Trustee of indemnity reasonably satisfactory to it; however,
such provision does not affect the right to sue for enforcement of any overdue payment on a Note by the Holder thereof. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Outstanding Notes may direct the
Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except default in payment of principal, premium or interest) if it determines in good faith that withholding the notice is in the
interest of the Holders. The Company is required to file annual reports with the Trustee as to the absence or existence of defaults. 
  

	15.	Trustee Dealings with the Company. 

 Subject to certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and
collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 

 

	16.	No Personal Liability of Directors, Officers, Employees and Stockholders. 

 No director, officer, employee, incorporator, stockholder, member, partner or trustee of the Company or any Subsidiary Guarantor, as such, shall have any liability for any obligations of the Company or
any Subsidiary Guarantor under the notes, the Indenture or the Subsidiary Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for issuance of the Notes.

	17.	Authentication.

Note shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Note. 

 

	18.	Abbreviations. 

 Customary

	19.	Governing Law. 

 THIS NOTE
SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED
THEREBY. 
  

	20.	CUSIP Numbers. 

 Pursuant
to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and has directed the Trustee to use CUSIP numbers in notices of redemption as a
convenience to the Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

 THE COMPANY WILL FURNISH TO ANY HOLDER OF NOTES UPON WRITTEN REQUEST AND WITHOUT CHARGE TO THE HOLDER A COPY OF THE ORIGINAL
