 The terms and provisions contained in the forms of the Notes annexed hereto as Exhibit A and Exhibit B,
shall constitute, and are hereby expressly made, a part of this Indenture and, to the extent applicable, the Company, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and
to be bound thereby. 
 Notes offered and sold in reliance on Rule 144A shall be issued initially in the form of one or more permanent Global

 -29- 








 Section 2.02. Execution and Authentication; Aggregate Principal Amount. An Officer (who shall have
been duly authorized by all requisite corporate actions) shall sign the Notes for the Company by manual or facsimile signature. 
 If an
Officer whose signature is on a Note was an Officer at the time of such execution but no longer holds that office or position at the time the Trustee authenticates the Note, the Note shall nevertheless be valid. 
 A Note shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Note. The signature shall
be conclusive evidence, and the only evidence, that the Note has been authenticated under this Indenture. 
 The Trustee shall authenticate
(i) Initial Notes for original issue in the aggregate principal amount not to exceed $115,000,000 and (ii) Exchange Notes from time to time for issue only pursuant to the Registration Rights Agreement in exchange for a like principal
amount of Notes. In addition, each Officers’ Certificate shall specify the amount of Notes to be authenticated and the date on which the Notes are to be authenticated, whether the Notes are to be Initial Notes or Exchange Notes. All Notes
issued under this Indenture shall vote and consent together on all matters as one class and no series of Notes shall have the right to vote or consent as a separate class on any matter. 
 The Trustee may appoint an authenticating agent (the “Authenticating Agent”) reasonably acceptable to the Company to authenticate Notes.
Unless otherwise provided in the appointment, an Authenticating Agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such Authenticating Agent. An
Authenticating Agent has the same rights as an Agent to deal with the Company and Affiliates of the Company.

registration of transfer or for exchange (the “Registrar”), (b) Notes may be presented or surrendered for payment (the “Paying Agent”) and (c) notices and demands to or upon the Company in respect of the
Notes and this Indenture may be served. The Registrar shall keep a register of the Notes and of their transfer and exchange. The Company, upon prior written notice to the Trustee, may have one or more co-Registrars and one or more additional Paying
Agents reasonably acceptable to the Trustee. The term “Paying Agent” includes any additional Paying Agent. Neither the Company nor any Affiliate of the Company may act as Paying Agent. 
 The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture, which agreement shall incorporate the
provisions of the TIA and implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee in writing, in advance, of the name and address of any such Agent. If the Company fails to maintain a Registrar or
Paying Agent, or fails to give the foregoing notice, the Trustee shall act as such, as shall be entitled to appropriate compensation therefore, pursuant to Section 7.07. 
 The Company initially appoints the Trustee as Registrar, Paying Agent and agent for service of demands and notices in connection with the Notes. The
Paying Agent or Registrar may resign upon thirty (30) days’ written notice to the Company. 
  

 -30- 








 The Company appoints The Depositary Trust Company as Depositary. 
 Section 2.04. Obligations of Paying Agent. The Company shall require each Paying Agent other than the Trustee to agree in writing that such Paying
Agent shall hold separate and apart from, and not commingle with any other properties, for the benefit of the Holders or the Trustee, all assets held by the Paying Agent for the payment of principal of, or interest on, the Notes (whether such assets
have been distributed to it by the Company or any other obligor on the Notes), and the Paying Agent shall promptly notify the Trustee in writing of any Default by the Company (or any other obligor on the Notes) in making any such payment. The
Company at any time may require a Paying Agent to distribute all assets held by it to the Trustee and account for any assets disbursed and the Trustee may at any time during the continuance of any payment Default, upon written request to a Paying
Agent, require such Paying Agent to distribute all assets held by it to the Trustee and to account for any assets distributed. Upon receipt by the Trustee of all assets that shall have been delivered by the Company to the Paying Agent, the Paying
Agent shall have no further liability for such assets. 
 Section 2.05. 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 the Holders and shall otherwise comply with TIA Section 312(b). If the Trustee is not the Registrar, the Company shall furnish or cause the
Registrar to furnish to the Trustee before each Record Date and at such other times as the Trustee may request in writing a list as of such date and in such form as the Trustee may reasonably request of the names and addresses of the Holders, which
list may be conclusively relied upon by the Trustee. 
 Section 2.06. Transfer and Exchange. Subject to the provisions of Sections
2.14 and 2.15, when Notes are presented to the Registrar or a co-Registrar with a request to register the transfer of such Notes or to exchange such Notes for an equal principal amount of Notes of other authorized denominations, the
Registrar or co-Registrar shall register the transfer or make the exchange as requested; provided, however, that the Notes presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a
written instrument of transfer in form satisfactory to the Company and the Registrar or co-Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing and such other documents as the Registrar or Co-Registrar may
reasonably require. To permit registrations of transfers and exchanges, the Company shall issue and the Trustee shall authenticate Notes at the Registrar’s or co-Registrar’s request. No service charge shall be made for any registration of
transfer or exchange, but the Company or the Trustee may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge
payable upon exchanges or transfers pursuant to Section 2.10, 3.07, 4.15, 4.16 or 9.05, in which event the Company shall be responsible for the payment of such taxes). 
 The Registrar or co-Registrar shall not be required to register the transfer or exchange of any Note (i) during a period beginning at the opening of
business fifteen (15) days before the mailing of a notice of redemption of Notes and ending at the close of business on the day of such mailing and (ii) selected for redemption in whole or in part pursuant to Article Three, except
the unredeemed portion of any Note being redeemed in part. 
 Any Holder of a Global Note shall, by acceptance of such Global Note, agree
that transfers of beneficial interests in such Global Note may be effected only through the Depository, in accordance with this Indenture and the Applicable Procedures. 
  


 -31- 








 Section 2.07. Replacement Notes. If a mutilated Note is surrendered to the Trustee or if the
Holder of a Note claims in writing that the Note has been lost, destroyed or wrongfully taken, then, in the absence of written notice to the Company or the Trustee that such Note has been acquired by a protected purchaser, the Company shall issue
and the Trustee shall authenticate a replacement Note of like tenor and principal amount and bearing a number not contemporaneously outstanding if the Trustee’s requirements are met. Except with respect to mutilated Notes, if required by the
Trustee or the Company, such Holder must provide an affidavit of lost certificate and an indemnity bond or other indemnity, sufficient in the judgment of both the Company and the Trustee, to protect the Company, the Trustee or any Agent from any
loss which any of them may suffer if a Note is replaced. The Company may charge such Holder for its reasonable out-of-pocket expenses in replacing a Note, including reasonable fees and expenses of its counsel and of the Trustee and its counsel. In
case any mutilated, lost, destroyed or wrongfully taken Note has become or is about to become due and payable, the Company in its discretion may pay such Note instead of issuing a new Note in replacement thereof. Every replacement Note shall
constitute an additional obligation of the Company, entitled to the benefits of this Indenture, subject to Section 2.08. 
 Section 2.08. Outstanding Notes. Notes outstanding at any time are all the Notes that have been authenticated by the Trustee except those cancelled by it, those delivered to it for cancellation and those described in this
Section 2.08 as not outstanding. Subject to the provisions of Section 2.09, a Note does not cease to be outstanding because the Company or any of its Affiliates holds the Note. 
 If a Note is replaced pursuant to Section 2.07 (other than a mutilated Note surrendered for replacement), it ceases to be outstanding unless
the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note and replacement thereof pursuant to Section 2.07. 
 If on a Redemption Date or the Maturity Date the Paying Agent holds U.S. Legal Tender or U.S. Government Obligations sufficient to pay all of the
principal and interest due on the Notes payable on that date and is not prohibited from paying such money to the Holders thereof pursuant to the terms of this Indenture, then on and after that date such Notes cease to be outstanding and interest on
them ceases to accrue. 
 Section 2.09. Treasury Notes; When Notes Are Disregarded. In determining whether the Holders of the required
principal amount of Notes have concurred in any direction, waiver, consent or notice, Notes owned by the Company or any of its Affiliates shall be considered as though they are not outstanding, except that for the purposes of determining whether the
Trustee shall be protected in relying on any such direction, waiver or consent, only Notes which a Trust Officer of the Trustee actually knows are so owned shall be so considered. Notes so owned which have been pledged in good faith may be regarded
as outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Notes and that the pledgee is not the Company or any other obligor upon the Notes or any Affiliate of the Company or
of such other obligor. 
 Section 2.10. Temporary Notes. Until definitive Notes are ready for delivery, the Company may prepare and
execute and the Trustee shall authenticate temporary Notes upon receipt of a written order of the Company in the form of an Officers’ Certificate. The Officers’ Certificate shall specify the amount of temporary Notes to be authenticated
and the date on which the temporary Notes are to be authenticated. 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 upon receipt of a written order of the Company pursuant to Section 2.02 definitive Notes in exchange for temporary Notes. Until so exchanged, the temporary Notes shall be
entitled to the same benefits under this Indenture as definitive Notes. 
  

 -32- 








 Section 2.11. Cancellation. The Company at any time may deliver Notes previously authenticated
hereunder which the Company has acquired in any lawful manner, to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for transfer, exchange or payment. The Trustee, or at the
direction of the Trustee, the Registrar or the Paying Agent, and no one else, shall cancel all Notes surrendered for transfer, exchange, payment or cancellation. Subject to Section 2.07, the Company may not issue new Notes to replace
Notes that it has paid or delivered to the Trustee for cancellation. If the Company shall acquire any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Notes unless and until the
same are surrendered to the Trustee for cancellation pursuant to this Section 2.11. The Trustee shall dispose of all cancelled Notes in accordance with the Trustee’s customary procedures. 
 Section 2.12. CUSIP Numbers. A “CUSIP” number shall be printed on the Notes, and the Trustee shall use the CUSIP number in
notices of redemption, purchase or exchange as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number printed in the notice or on the Notes and
that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall promptly notify the Trustee of any change in the CUSIP number. 
 Section 2.13. Deposit of Moneys. Prior to 10:00 a.m. New York City time on each Interest Payment Date and the Maturity Date, the Company shall
deposit with the Paying Agent U.S. Legal Tender sufficient to make cash payments, if any, due on such Interest Payment Date or the Maturity Date, as the case may be. 
 Section 2.14. Book-Entry Provisions for Global Notes. 
 (a) The Global Notes initially shall
(i) be registered in the name of the Depository or the nominee of such Depository, (ii) be delivered to the Trustee as custodian for such Depository and (iii) bear legends as set forth in Exhibit C. 
 Members of, or participants in, the Depository (“Agent Members”) shall have no rights under this Indenture with respect to any Global
Note held on their behalf by the Depository, or the Trustee as its custodian, or under any 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 the 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 governing the exercise of the rights of a Holder of any Note. 
 (b) Transfers of the Global Notes shall be limited to transfers in whole, but not in part, to the Depository, its successors or their respective
nominees. Interests of beneficial owners in the Global Notes may be transferred or exchanged in accordance with the Applicable Procedures of the Depository and the provisions of Section 2.15, provided, however, that prior
to the expiration of the Restricted Period, transfers of beneficial interests in the Regulation S Global Note may not be made to a U.S. Person or for the account or benefit of a U.S. Person (other than an Initial Purchaser). In addition, Notes
in the form of certificated Notes in registered form in substantially the form set forth in Exhibit A hereto (the “Physical Notes”) shall be transferred to all beneficial owners in exchange for their beneficial interests in
the Global Notes if (i) the Depository notifies the Company that it is unwilling or unable to continue as Depository for the Global Notes and a successor Depository is not appointed by the Company within ninety (90) days of such notice or
(ii) an Event of Default has occurred and is continuing and the Registrar has received a request from the Depository to issue Physical Notes; provided that a beneficial interest in the Regulation S Global Note may not be exchanged for a
Physical Note or transferred to a Person who takes delivery thereof in the form of a Physical Note prior to the expiration of the Restricted Period. 
  

 -33- 








 (c) Any beneficial interest in one of the Global Notes that is transferred to a Person who takes delivery
in the form of an interest in another Global Note shall, upon transfer, cease to be an interest in such first Global Note and become a beneficial interest in such other Global Note and, accordingly, shall thereafter be subject to all transfer
restrictions, if any, and other procedures applicable to a beneficial interest in such other Global Notes for as long as it remains such an interest. 
 (d) In connection with any transfer or exchange of a portion of the beneficial interest in the Global Note to beneficial owners pursuant to paragraph (b), the Registrar shall (if one or more Physical Notes are
to be issued) reflect on its books and records the date and a decrease in the principal amount of the Global Note in an amount equal to the principal amount of the beneficial interest in the Global Note to be transferred, and the Company shall
execute, and the Trustee shall authenticate and deliver, one or more Physical Notes of like tenor and aggregate principal amount. 
 (e) In
connection with the transfer of an entire Global Note to beneficial owners pursuant to paragraph (b), the Global Notes shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall
authenticate and deliver, to each beneficial owner identified by the Depository in exchange for its beneficial interest in the Global Notes, an equal aggregate principal amount of Physical Notes of authorized denominations. 
 (f) Any Physical Note constituting a Restricted Security delivered in exchange for an interest in the Global Note pursuant to paragraph (b),
except as otherwise provided by paragraphs (a)(i)(x) and (c) of Section 2.15, bear the legend regarding transfer restrictions applicable to the Physical Notes set forth in Exhibit A. 
 (g) The Holder of a Global Note may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through
Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Notes. 
 Section 2.15. Special Transfer
Provisions. 
 (a) Transfers to Non-QIB Institutional Accredited Investors and Non-U.S. Persons. The following provisions
shall apply with respect to the registration of any proposed transfer of a Note constituting a Restricted Security to any Institutional Accredited Investor which is not a QIB or to any Non-U.S. Person: 
 (i) the Registrar shall register the transfer of any Note constituting a Restricted Security, whether or not such Note bears the Private
Placement Legend, if (x) the requested transfer is after October 1, 2009 or (y) (1) in the case of a transfer to an Institutional Accredited Investor which is not a QIB (excluding Non-U.S. Persons), the proposed transferee has
delivered to the Registrar a certificate substantially in the form of Exhibit D hereto or (2) in the case of a transfer to a Non-U.S. Person, the proposed transferor has delivered to the Registrar a certificate substantially in the form
of Exhibit E hereto; and 
 (ii) if the proposed transferor is an Agent Member holding a beneficial interest in the
Global Note, upon receipt by the Registrar of (x) the certificate, if any, required by paragraph (i) above and (y) instructions given in accordance with the Applicable Procedures and the Registrar’s procedures, 

  

 -34- 








 
whereupon (1) the Registrar shall reflect on its books and records the date and (if the transfer does not involve a transfer of outstanding Physical
Notes) a decrease in the principal amount of the Global Note in an amount equal to the principal amount of the beneficial interest in the Global Note to be transferred, and (2) the Company shall execute and the Trustee shall authenticate and
deliver one or more Physical Notes of like tenor and principal amount. 
 (b) Transfers to QIBs. The following provisions shall apply
with respect to the registration of any proposed transfer of a Note constituting a Restricted Security to a QIB (excluding transfers to Non-U.S. Persons): 
 (i) the Registrar shall register the transfer if such transfer is being made by a proposed transferor who has checked the box provided for on the form of Note stating, or has otherwise advised the Company and the
Registrar in writing, that the sale has been made in compliance with the provisions of Rule 144A to a transferee who has signed the certification provided for on the form of Note stating, or has otherwise advised the Company and the Registrar in
writing, that it is purchasing the Note for its own account or an account with respect to which it exercises sole investment discretion and that it and any such account is a QIB within the meaning of Rule 144A, and is aware that the sale to it is
being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Company as it has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is
relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A; and 
 (ii) if the proposed transferee is an Agent Member, and the Notes to be transferred consist of Physical Notes which after transfer are to be evidenced by an interest in the Global Note, upon receipt by the Registrar of instructions given in
accordance with the Applicable Procedures and the Registrar’s procedures, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Note in an amount equal to the principal amount of the
Physical Notes to be transferred, and the Trustee shall cancel the Physical Notes so transferred. 
 (c) Private Placement Legend.
Upon the transfer, exchange or replacement of Notes not bearing the Private Placement Legend, the Registrar shall deliver Notes that do not bear the Private Placement Legend. Upon the transfer, exchange or replacement of Notes bearing the Private
Placement Legend, the Registrar shall deliver only Notes that bear the Private Placement Legend unless (i) the circumstance contemplated by paragraph (a)(i)(x) of this Section 2.15 exists or (ii) there is delivered to
the Registrar an Opinion of Counsel reasonably satisfactory to the Company and the Trustee to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the
Securities Act. The Registrar shall not register a transfer of any Note unless such transfer complies with the restrictions on transfer of such Note set forth in this Indenture. In connection with any transfer of Notes, each Holder agrees by its
acceptance of the Notes to furnish the Registrar or the Company such certifications, legal opinions or other information as either of them may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or a
transaction not subject to, the registration requirements of the Securities Act; provided that the Registrar shall not be required to determine (but may rely on a determination made by the Company with respect to) the sufficiency of any such
certifications, legal opinions or other information. 
 (d) General. By its acceptance of any Note bearing the Private Placement
Legend, each Holder of such a Note acknowledges the restrictions on transfer of such Note set forth in this Indenture and in the Private Placement Legend and agrees that it shall transfer such Note only as provided in this Indenture. 
  

 -35- 








 The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any
restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any security (including any transfers between or among Agent Members or beneficial owners of interest in any Global Note)
other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial
compliance as to form with the express requirements hereof. 
 The Registrar shall retain copies of all letters, notices and other written
communications received pursuant to Section 2.14 or this Section 2.15. The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the
giving of reasonable written notice to the Registrar.

 (1) at least 65% of the principal amount of Notes originally issued under this Indenture remains outstanding immediately after any such
redemption; and 
 (2) the Company makes such redemption not more than 120 days after the consummation of any such Equity
Offering. 
 Section 3.02. Mandatory Redemption. The Company is not required to make any mandatory redemption or sinking fund payments
with respect to the Notes. 
 Section 3.03. Selection of Notes to Be Redeemed. If fewer than all of the Notes are to be redeemed
pursuant to the provisions of this Indenture, the Trustee shall select the Notes to be redeemed (1) in compliance with the requirements of the principal national securities exchange, if any, on which such Notes are listed or (2) if such
Notes are not then listed on a national securities exchange, on a pro rata basis, by lot or by such method as the Trustee may reasonably determine is fair and appropriate, provided that if any such partial redemption is made
with the proceeds of an Equity Offering, the Trustee will select the Notes only on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to DTC procedures), unless such method is otherwise
prohibited. The Trustee shall make the selection from the Notes outstanding and not previously called for redemption and shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for
partial redemption, the principal amount thereof, to be redeemed. 
 No Notes of a principal amount of $1,000 or less shall be redeemed in
part and Notes of a principal amount in excess of $1,000 may be redeemed in part in multiples of $1,000 only. The Trustee may select for redemption portions (equal to $1,000 or any integral multiple thereof) of the principal amount of Notes that
have denominations larger than $1,000. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. 
 Section 3.04. Notice of Redemption. At least 30 days but not more than 60 days before the Redemption Date, the Company shall mail or cause to be mailed a notice of redemption by first class mail, postage
prepaid, to each Holder whose Notes are to be redeemed at its registered address, with a copy to the Trustee and any Paying Agent. At the Company’s written request delivered at least fifteen days prior to the date such notice is to be given
(unless a shorter period shall be acceptable to the Trustee), the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense, provided the Company provides the Trustee with all information required for
such notice of redemption. Failure to give Notice of redemption, or any defect therein to any Holder of any Note selected for redemption shall not impair or affect the validity of the redemption of any other Note. 
 Each notice of redemption shall identify the Notes to be redeemed and shall state: 
 (1) the Redemption Date; 
 (2) the Redemption Price and the amount of accrued interest, if any, to be paid; 
 (3) the
name and address of the Paying Agent; 
  

 -37- 








 (4) the CUSIP number; 
 (5) the subparagraph of the Notes pursuant to which such redemption is being made; 
 (6) the place where such Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price plus accrued
interest, if any; 
 (7) that, unless the Company fails to deposit with the Paying Agent funds in satisfaction of the
applicable Redemption Price plus accrued interest, if any, the Notes cease to accrete in value and interest on Notes called for redemption ceases to accrue on and after the Redemption Date in accordance with Section 3.06, and the only
remaining right of the Holders of such Notes is to receive payment of the Redemption Price plus accrued interest, if any, upon surrender to the Paying Agent of the Notes redeemed; 
 (8) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the Redemption
Date, and upon surrender of such Note, a new Note or Notes in the aggregate principal amount equal to the unredeemed portion thereof shall be issued in the name of the Holder thereof upon cancellation of the original Note (or appropriate adjustments
to the amount and beneficial interests in the Global Note will be made); and 
 (9) if fewer than all the Notes are to be
redeemed, the identification of the particular Notes (or portion thereof) to be redeemed, as well as the aggregate principal amount of Notes to be redeemed and the aggregate principal amount of Notes to be outstanding after such partial redemption.

 If any of the Notes to be redeemed is in the form of a Global Note, then the Company shall modify such notice to the extent necessary to
accord with the procedures of the Depository applicable to redemption. 
 Section 3.05. Effect of Notice of Redemption. Once notice of
redemption is mailed in accordance with Section 3.04, Notes or portions thereof called for redemption shall become irrevocably due and payable on the Redemption Date and at the Redemption Price plus accrued interest thereon. Upon
surrender to the Trustee or Paying Agent, such Notes or portions thereof called for redemption shall be paid at the Redemption Price plus accrued interest thereon, to the Redemption Date, but installments of interest thereon, the maturity of which
is on or prior to the Redemption Date, shall be payable to Holders of record at the close of business on the relevant Record Dates referred to in the Notes. 
 Section 3.06. Deposit of Redemption Price. Not later than 10:00 a.m. local time in the place of payment on the Redemption Date, the Company shall deposit with the Paying Agent U.S. Legal Tender sufficient to
pay the Redemption Price plus accrued interest, if any, of all Notes or portions thereof to be redeemed on that date. 
 The Paying Agent
shall promptly return to the Company any U.S. Legal Tender so deposited which is not required for that purpose, except with respect to monies owed as obligations to the Trustee pursuant to Article Seven. 
 If the Company complies with the preceding paragraph, then, unless the Company defaults in the payment of such Redemption Price plus accrued interest, if
any, interest on the Notes to be redeemed shall cease to accrue and the Notes shall cease to accrete in value on and after the applicable Redemption Date, whether or not such Notes are presented for payment. 
  

 -38- 








 Section 3.07. Notes Redeemed in Part. Upon surrender of a Note that is to be redeemed in part, the
Company shall issue and the Trustee shall authenticate for the Holder at the expense of the Company a new Note or Notes equal in principal amount to the unredeemed portion of the Note surrendered. 
 ARTICLE FOUR 
 Covenants

 Section 4.01. Payment of Notes. The Company shall pay the principal of, or premium, if any, and interest, if any, on the Notes
on the dates and in the manner provided in the Notes and in this Indenture. An installment of principal of, or premium, if any, or interest, if any, on the Notes shall be considered paid on the date it is due if the Trustee or Paying Agent (other
than the Company or an Affiliate of the Company) holds at 10:00 a.m. (New York time) on that date U.S. Legal Tender designated for and sufficient to pay the installment in full and is not prohibited from paying such money to the Holders pursuant to
the terms of this Indenture. The Company shall pay interest on overdue principal at 1% per annum in excess of the rate per annum set forth in the Notes, and it shall pay interest on overdue installments of interest at the same rate to the
extent lawful. 
 Notwithstanding anything to the contrary contained in this Indenture, the Company may, to the extent it is required to do
so by law, deduct or withhold income or other similar taxes imposed by the United States from principal or interest payments hereunder. 
 Section 4.02. Maintenance of Office or Agency. The Company shall maintain the office or agency required under Section 2.03. The Company shall give prior written notice to the Trustee and the Holders of the location, and
any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the Corporate Trust Office and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. 
 Section 4.03. Corporate Existence. Except as otherwise permitted by Articles Four, Five, and Ten the Company shall do or
cause to be done, at its own cost and expense, all things necessary to preserve and keep in full force and effect its corporate existence and the limited liability company, partnership or corporate existence of each of its Restricted Subsidiaries in
accordance with the respective organizational documents of the Company and each such Restricted Subsidiary, as the case may be, and the material rights (charter and statutory) and franchises of the Company and each such Restricted Subsidiary;
provided, however, that the Company shall not be required to preserve, with respect to itself, any material right or franchise and, with respect to any of its Restricted Subsidiaries, any such existence, material right or franchise, if
the Board of Directors of the Company, shall determine in good faith that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Restricted Subsidiaries, taken as a whole. 
 Section 4.04. Payment of Taxes and Other Claims. The Company shall pay or discharge or cause to be paid or discharged, before the same shall
become delinquent, (i) all material taxes, assessments and governmental charges (including withholding taxes and any penalties, interest and additions to taxes) levied or imposed upon it or any of its Restricted Subsidiaries or its properties
or any of its Restricted Subsidiaries’ properties and (ii) all material lawful claims for labor, materials and supplies that, if unpaid, might by law become a Lien upon its properties or any of its Restricted Subsidiaries’ properties;
provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being or shall be contested in good
faith by appropriate proceedings properly instituted and diligently conducted for which adequate reserves, to the extent required under GAAP, have been taken.

 Section 4.05. Maintenance of Properties and Insurance. 
 (a) The Company shall, and shall cause each of its Restricted Subsidiaries to, maintain its properties in good working order and condition in all
material respects (subject to ordinary wear and tear) and make all necessary repairs, renewals, replacements, additions, betterments and improvements thereto and actively conduct and carry on its business; provided, however, that
nothing in this Section 4.05 shall prevent the Company or any of its Restricted Subsidiaries from discontinuing the operation and maintenance of any of its properties if such discontinuance is, in the good faith judgment of the Board of
Directors or other governing body of the Company or the Subsidiary concerned, as the case may be, desirable in the conduct of its businesses and is not disadvantageous in any material respect to the Holders. 
 (b) The Company shall maintain insurance (including appropriate self-insurance) against loss or damage of the kinds that, in the good faith judgment of
the Company, are adequate and appropriate for the conduct of the business of the Company and its Restricted Subsidiaries in a prudent manner, with reputable insurers or with the government of the United States or an agency or instrumentality
thereof, in such amounts, with such deductibles, and by such methods as shall be customary, in the good faith judgment of the Company, for companies similarly situated in the industry in which the Company and its Restricted Subsidiaries are engaged.

 Section 4.06. Compliance Certificate; Notice of Default. 
 (a) The Company and each Guarantor shall deliver to the Trustee, within ninety (90) days after the end of the Company’s fiscal year, an
Officers’ Certificate stating that a review of the activities of the Company and its Restricted Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers (one of whom is the principal executive
officer, principal financial officer or principal accounting officer) with a view to determining whether they have kept, observed, performed and fulfilled their obligations under this Indenture and further stating, as to each such Officer signing
such certificate, that to the best of such Officer’s actual knowledge the Company and its Restricted Subsidiaries during such preceding fiscal year have kept, observed, performed and fulfilled each and every condition and covenant under this
Indenture and no Default or Event of Default occurred during such year and at the date of such certificate there is no Default or Event of Default that has occurred and is continuing or, if such signers do know of such Default or Event of Default,
the certificate shall describe the Default or Event of Default and its status with particularity. The Officers’ Certificate shall also notify the Trustee should the Company elect to change the manner in which it fixes its fiscal year end.

 (b) The annual financial statements delivered pursuant to Section 4.08 shall be accompanied by a written report of the
Company’s independent accountants (who shall be a firm of established national reputation) that in conducting their audit of such financial statements nothing has come to their attention that would lead them to believe that the Company has
violated any provisions hereof insofar as they relate to accounting matters or, if any such violation has occurred, specifying the nature and period of existence thereof, it being understood that such accountants shall not be liable directly or
indirectly to any Person for any failure to obtain knowledge of any such violation. 
 (c) (i) If any Default or Event of Default has
occurred and is continuing or (ii) if any Holder seeks to exercise any remedy hereunder with respect to a claimed Default under this Indenture or the Notes, the Company shall deliver to the Trustee, at its address set forth in
Section 11.02, by registered or certified mail or by telegram, telex or facsimile transmission followed by hard copy by registered or certified mail an Officers’ Certificate specifying such event, notice or other action within five
(5) Business Days of its becoming aware of such occurrence. 
  

 -40- 








 Section 4.07. Compliance with Laws. The Company shall, and shall cause each of its Restricted
Subsidiaries to, comply with all applicable statutes, rules, regulations, orders and restrictions of the United States, all states and municipalities thereof, and of any governmental department, commission, board, regulatory authority, bureau,
agency and instrumentality of the foregoing, in respect of the conduct of its businesses and the ownership of its properties, except for such noncompliances as are not in the aggregate reasonably likely to have a material adverse effect on the
financial condition or results of operations of the Company and its Restricted Subsidiaries, taken as a whole or the ability of the Company to perform its obligations hereunder. 
 Section 4.08. Reports to Holders. Whether or not required by the rules and regulations of the Commission, so long as any Notes are outstanding,
the Company will furnish to the Trustee and, upon request, to the Holders: 
 (1) all quarterly and annual financial
information that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if the Company were required to file such Forms, including a “Management’s Discussion and Analysis of Financial Condition and Results
of Operations” that describes the financial condition and results of operations of the Company and its consolidated Subsidiaries (showing in reasonable detail, either on the face of the financial statements or in the footnotes thereto and in
Management’s Discussion and Analysis of Financial Condition and Results of Operations, the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of
operations of the Unrestricted Subsidiaries of the Company, if any) and, with respect to the annual information only, a report thereon by the Company’s certified independent accountants; and 
 (2) all current reports that would be required to be filed with the Commission on Form 8-K if the Company were required to file such
reports, 
 in each case within the time periods specified in the Commission’s rules and regulations, provided that any breach of this
Section 4.08 shall be cured upon the furnishing of such late report within 20 days of the date on which such report was required to be furnished. 
 The Company will hold a quarterly conference call for the Holders and securities analysts to discuss such financial information no later than 10 business days after distribution of such financial information.

 Notwithstanding the foregoing, the Company may satisfy such requirements prior to the effectiveness of the registration statement
contemplated by the Registration Rights Agreement by filing with the Commission such registration statement within the time period required for such filing as specified in the Registration Rights Agreement, to the extent that any such registration
statement contains substantially the same information as would be required to be filed by the Company if it were subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, and by providing the Trustee and
Holders with such Registration Statement (and any amendments thereto) promptly following the filing thereof. 
  

 -41- 








 In addition, following the consummation of the Exchange Offer, whether or not required by the rules and
regulations of the Commission, the Company will file a copy of all such information and reports with the Commission for public availability within the time periods specified in the Commission’s rules and regulations (unless the Commission will
not accept such a filing). In addition, the Company has agreed that, prior to the consummation of the Exchange Offer, for so long as any Notes remain outstanding, it will furnish to the Holders upon their request, the information required to be
delivered pursuant to Rule 144(A)(d)(4) under the Securities Act. 
 The receipt by the Trustee of any such reports and documents pursuant to
this Section 4.08 shall not constitute notice or constructive notice of any information contained in such documents or determinable from information contained in such documents, including the Company’s compliance with any covenants
hereunder (as to which the Trustee is entitled to rely exclusively on an Officers’ Certificate). 
 Section 4.09. Waiver of Stay,
Extension or Usury Laws. The Company and each of the Guarantors covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any
stay or extension law or any usury law or other law that would prohibit or forgive the Company and each of the Guarantors from paying all or any portion of the principal of, premium, if any, or interest on the Notes as contemplated herein, wherever
enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and (to the extent that it may lawfully do so) the Company and each of the Guarantors hereby expressly waives all benefit or
advantage of any such law, and covenants that it shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

 Section 4.10. Limitation on Restricted Payments. The Company will not, and will not cause or permit any of its Restricted
Subsidiaries to, directly or indirectly: 
 (a) declare or pay any dividend or make any distribution (other than dividends or distributions
payable in Qualified Capital Stock of the Company and dividends and distributions payable to the Company or another Restricted Subsidiary of the Company) on or in respect of shares of Capital Stock of the Company or its Restricted Subsidiaries to
holders of such Capital Stock; 
 (b) purchase, redeem or otherwise acquire or retire for value any Capital Stock of the Company or its
Restricted Subsidiaries (other than any such Capital Stock held by the Company or any Restricted Subsidiary);

Indebtedness of the Company or any Guarantor, that is subordinate or junior in right of payment to the Notes or a Guarantee; or 
 (d) make
any Investment (other than Permitted Investments); 
 (each of the foregoing actions set forth in clauses (a), (b), (c) and (d) being referred to
as a “Restricted Payment”).

“Convertible Record Date”): 
 (i) a Default or an Event of Default shall not have occurred and be continuing;

  

 -42- 








 (ii) the Company is able to incur at least $1.00 of additional Indebtedness (other than
Permitted Indebtedness) in compliance with Section 4.12; and 
 (iii) 50% of the aggregate amount of accrued and
unpaid interest due on the Convertible Subordinated Notes’ next interest payment date following the Convertible Record Date (the “Convertible Interest Payment Date”) is equal to or less than the sum of: 
 (A) 50% of the cumulative Consolidated Net Income (or if cumulative Consolidated Net Income is a loss, minus 100% of such loss) of
the Company earned during the period beginning on the first day of the first fiscal quarter after the Issue Date and ending on the last day of the Company’s most recent fiscal quarter ending prior to the Convertible Record Date for which
financial statements are available (the “Reference Date”) (treating such period as a single accounting period); plus  
 (B) 100% of the aggregate net cash proceeds received by the Company from any Person (other than a Subsidiary of the Company) from the issuance and sale subsequent to the Issue Date and on or prior to the Reference
Date of Qualified Capital Stock of the Company (excluding any net proceeds from an Equity Offering to the extent used to redeem Notes pursuant to the provisions described in Section 3.01); plus  
 (C) without duplication of any amounts included in clause (iii)(B) above, 100% of the aggregate net cash proceeds of any equity

to the provisions described in Section 3.01); plus  
 (D) 100% of the aggregate net cash proceeds received
from the issuance of Indebtedness or shares of Disqualified Capital Stock of the Company that have been converted into or exchanged for Qualified Capital Stock of the Company subsequent to the Issue Date and on or prior to the Reference Date;
plus  
 (E) an amount equal to the sum of (i) the net reduction in the Investments (other than Permitted
Investments) made by the Company or any of its Restricted Subsidiaries in any Person resulting from repurchases, repayments or redemptions of such Investments by such Person, proceeds realized on the sale of such Investment and proceeds representing
the return of capital (excluding dividends and distributions otherwise included in Consolidated Net Income), in each case received by the Company or any of its Restricted Subsidiaries, and (ii) to the extent such Person is an Unrestricted
Subsidiary, the portion (proportionate to the Company’s equity interest in such Subsidiary) of the Fair Market Value of the net assets of such Unrestricted Subsidiary at the time such Unrestricted Subsidiary is designated a Restricted
Subsidiary; provided, however, that the foregoing sum shall not exceed, in the case of any such Person or Unrestricted Subsidiary, the amount of Investments (excluding Permitted Investments) previously made by the Company or any of its
Restricted Subsidiaries in such Person or Unrestricted Subsidiary; minus, 
  

 -43- 








 (F) any amounts previously paid to the Holders of the Convertible Subordinated Notes
pursuant to this subsection (iii), (such sum being referred to as the “Build-up Amount”), the Company is required to pay 50% (the “Required Amount”) and, should the Build-up Amount exceed the Required Amount (the “Excess
Amount”), may pay the Excess Amount in an amount up to 100% of the remaining interest then due on the Convertible Interest Payment Date after payment of the Required Amount, in cash to the holders of the Convertible Subordinated Notes. The
Company may, subject to the other provisions of this Indenture, use any amounts remaining after such interest payment is made on the Convertible Subordinated Notes for any other lawful purpose. 
 In the case of clauses (iii)(B) and (C) above, any net cash proceeds from issuances and sales of Qualified Capital Stock of the Company financed
directly or indirectly using funds borrowed from the Company or any Subsidiary of the Company, shall be excluded until and to the extent such borrowing is repaid. 
 If no Default or Event of Default has occurred and is continuing or would exist after giving effect thereto, the provisions of this covenant do not prohibit the repurchase or other acquisition of shares of Capital
Stock of the Company, from employees, former employees, directors or former directors of the Company or its Restricted Subsidiaries (or permitted transferees of such employees, former employees, directors or former directors), pursuant to the terms
of the agreements (including employment agreements) or plans (or amendments thereto) or other arrangements approved by the Board of Directors of the Company under which such shares were granted, issued or sold or such other repurchases or
acquisitions as may be approved by the Board of Directors of the Company; provided, however, that the aggregate amount of such repurchases and other acquisitions in any calendar year shall not exceed $250,000 plus up to $250,000
of any unutilized amounts from the preceding calendar year; provided, further, however, that such amount in any calendar year may be increased by an amount not to exceed the cash proceeds of key man life insurance policies
received by the Company (to the extent contributed to the Company) and its Restricted Subsidiaries subsequent to the Issue Date. 
 On the
last business day of each fiscal quarter the Company shall deliver to the Trustee an Officers’ Certificate stating that the Restricted Payments made by the Company during such fiscal quarter complied with this Indenture and setting forth in
reasonable detail the basis upon which the required calculations were computed, which calculations may be based upon the Company’s latest available internal quarterly financial statements. 
 Section 4.11. Limitations on Transactions with Affiliates. 
 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into or permit to exist any transaction or series of related transactions (including, without
limitation, the purchase, sale, lease or exchange of any property or the rendering of any service) with, or for the benefit of, any of its Affiliates (each an “Affiliate Transaction”), other than 
 (x) Affiliate Transactions permitted under paragraph (b) below, and 
 (y) Affiliate Transactions on terms that are no less favorable than those that might reasonably have been obtained in a comparable
transaction at such time on an arm’s-length basis from a Person that is not an Affiliate of the Company or such Restricted Subsidiary. 
 All Affiliate Transactions (and each series of related Affiliate Transactions which are similar or part of a common plan) involving aggregate payments or other property with a Fair Market Value in excess of $2.5 million shall be approved by
a majority of the members of the Board of Directors of the Company (including a majority of the disinterested members thereof), as the case may be, such approval to be evidenced by a Board Resolution stating that such Board of Directors has
determined that such transaction complies with the foregoing provisions. If the Company or any Restricted Subsidiary of 

  

 -44- 








 
the Company enters into an Affiliate Transaction (or a series of related Affiliate Transactions related to a common plan) that involves an aggregate Fair
Market Value of more than $5.0 million, the Company shall, prior to the consummation thereof, obtain a favorable opinion as to the fairness of the financial terms of such transaction or series of related transactions to the Company or the relevant
Restricted Subsidiary, as the case may be, from an Independent Financial Advisor and file the same with the Trustee. 
 (b) The restrictions
set forth in paragraph (a) of this covenant shall not apply to: 
 (1) reasonable fees and compensation paid to and
indemnity provided on behalf of, officers, directors, employees or consultants of the Company or any Restricted Subsidiary of the Company as determined in good faith by the Company’s Board of Directors or senior management; 
 (2) transactions exclusively between or among the Company and any of its Restricted Subsidiaries or exclusively between or among such
Restricted Subsidiaries, provided such transactions are not otherwise prohibited by this Indenture; 
 (3) any
agreement as in effect as of the Issue Date or any transaction contemplated thereby and any amendment thereto or any replacement agreement thereto so long as any such amendment or replacement agreement is not more disadvantageous to the Holders in
any material respect than the original agreement as in effect on the Issue Date; 
 (4) Restricted Payments permitted by this
Indenture and Permitted Investments of the type described in clauses (9) and (11) of the definition thereof; 
 (5)
any merger or other transaction with an Affiliate solely for the purpose of reincorporating the Company in another jurisdiction or creating a holding company of the Company; 
 (6) any employment, stock option, stock repurchase, employee benefit compensation, business expense reimbursement, severance, termination
or other employment-related agreements, arrangements or plans entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business; 
 (7) transactions to effect the Transactions and the payment of all fees and expenses related to the Transactions; and 
 (8) the issuance of Qualified Capital Stock of the Company. 
 Section 4.12. Limitation on Incurrence of Additional Indebtedness. 
 (a) The Company will not,
and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume, guarantee, acquire, become liable, contingently or otherwise, with respect to, or otherwise become responsible for payment of (collectively,
“incur”) any Indebtedness (other than Permitted Indebtedness); provided, however, that if no Default or Event of Default shall have occurred and be continuing at the time or as a consequence of the incurrence of any
such Indebtedness, the Company or any of its Restricted Subsidiaries that is or, upon such incurrence, becomes a Guarantor may incur Indebtedness (including, without limitation, Acquired Indebtedness) if (x) on the date of the incurrence of
such Indebtedness the Consolidated Fixed Charge Coverage Ratio of the Company will be, after giving effect to the incurrence thereof, greater than 2.5 to 1.0 and (y) any such Indebtedness (i) other than Indebtedness described in clauses
(4), (6) (to the extent incurred in respect of clause (4)), (7) (to the 

  

 -45- 








 
extent incurred in respect of clause (4)) and (9) of the definition thereof) shall constitute Permitted Subordinated Indebtedness or (ii) that
consists of Disqualified Capital Stock shall constitute Permitted Disqualified Capital Stock. 
 (b) The Company will not, and will not
permit any of its Domestic Restricted Subsidiaries to, directly or indirectly, incur any Indebtedness which by its terms (or by the terms of any agreement governing such Indebtedness) is subordinated in right of payment to any other Indebtedness of
the Company or such Domestic Restricted Subsidiary unless such Indebtedness is also by its terms (or by the terms of any agreement governing such Indebtedness) made expressly subordinate to the Obligations of the Company or such Domestic Restricted
Subsidiary under (i) in the case of the Company, the Notes and this Indenture or (ii) in the case of such Domestic Restricted Subsidiary, its Guarantee and this Indenture, in each case, to the same extent and in the same manner as such
Indebtedness is subordinated pursuant to subordination provisions that are most favorable to the holders of any other Indebtedness of the Company or such Domestic Restricted Subsidiary. 
 Section 4.13. Limitation on Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries. The Company will not, and will not cause or
permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or permit to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary of the Company to: 
 (1) pay dividends or make any other distributions on or in respect of its Capital Stock; 
 (2) make loans or advances or to pay any Indebtedness or other obligation owed to the Company or any other Restricted Subsidiary of the
Company; or 
 (3) transfer any of its property or assets to the Company or any other Restricted Subsidiary of the Company,

 except for such encumbrances or restrictions existing under or by reason of: 
 (a) applicable law, rule or regulation; 
 (b) this Indenture and the Collateral Agreements; 
 (c) customary non-assignment provisions of any lease of any Restricted
Subsidiary of the Company to the extent such provisions restrict the transfer of the lease or the property leased thereunder; 
 (d) any
instrument governing Acquired Indebtedness, which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person or the properties or assets of the Person so acquired; 
 (e) agreements existing on the Issue Date (including the Convertible Subordinated Notes Indenture and the Credit Agreement) to the extent and in the
manner such agreements are in effect on the Issue Date; 
 (f) restrictions on the transfer of assets subject to any Lien permitted under
this Indenture; 
 (g) restrictions imposed by any agreement to sell assets or Capital Stock permitted under this Indenture to any Person
pending the closing of such sale; 
  

 -46- 








 (h) provisions in joint venture agreements and other similar agreements (in each case relating solely to
the respective joint venture or similar entity or the equity interests therein) entered into in the ordinary course of business; 
 (i)
restrictions contained in the terms of the Purchase Money Indebtedness or Capitalized Lease Obligations not incurred in violation of this Indenture; provided, that such restrictions relate only to the assets financed with such Indebtedness;

 (j) restrictions in other Indebtedness incurred in compliance with Section 4.12 (including Permitted Indebtedness);
provided that such restrictions, taken as a whole, are, in the good faith judgment of the Board of Directors of the Company, no more materially restrictive with respect to such encumbrances and restrictions than those customary in comparable
financings (as reasonably determined by the Company) and the Company determines that any such encumbrance or restriction will not materially affect the Company’s ability to make principal, premium, if any, or interest payments on the Notes or
any Guarantor’s ability to honor its Guarantee in respect thereof; or 
 (k) an agreement governing Indebtedness incurred to Refinance
the Indebtedness issued, assumed or incurred pursuant to an agreement referred to in clause (b), (d) or (e) above; provided, however, that the provisions relating to such encumbrance or restriction contained in any such
Indebtedness are no less favorable to the Company in any material respect as determined by the Board of Directors of the Company in their reasonable and good faith judgment than the provisions relating to such encumbrance or restriction contained in
agreements referred to in such clause (b), (d) or (e). 
 Section 4.14. Additional Guarantees. If the Company or any of its
Restricted Subsidiaries acquires or creates another Domestic Restricted Subsidiary after the Issue Date (other than an Unrestricted Subsidiary), then the Company shall cause such Domestic Restricted Subsidiary to:

unconditionally guarantee on a senior secured basis all of the Company’s obligations under the Notes and this Indenture on the terms set forth in this Indenture; 
 (2) execute and deliver to the Trustee and the Collateral Agent amendments to the Collateral Agreements or additional Collateral
Agreements and take such other actions as may be necessary to grant to the Collateral Agent, for the benefit of the Holders, a perfected Lien in the assets other than Excluded Collateral of such Domestic Restricted Subsidiary, including the filing
of Uniform Commercial Code financing statements in such jurisdictions or such other actions as may be required by the Collateral Agreements; 
 (3) take such actions necessary or as the Collateral Agent reasonably determines to be advisable to grant to the Collateral Agent for the benefit of the Holders a perfected Lien in the assets other than Excluded
Collateral of such new Domestic Restricted Subsidiary, subject to the Permitted Liens, including the filing of Uniform Commercial Code financing statements in such jurisdictions as may be required by the Security Agreement or by law or as may be
reasonably requested by the Collateral Agent; 
 (4) take such further action and execute and deliver such other documents
necessary or as reasonably requested by the Trustee or the Collateral Agent to effectuate the foregoing; and 
 (5) deliver to
the Trustee an Opinion of Counsel that such supplemental indenture and any other documents required to be delivered have been duly authorized, executed and delivered by such Domestic Restricted Subsidiary and constitute legal, valid, binding and
enforceable obligations of such Domestic Restricted Subsidiary and such other opinions regarding the perfection of such Liens in the assets of such Domestic Restricted Subsidiary as provided for in this Indenture.

 Section 4.15. Repurchase upon Change of Control. 
 (a) Upon the occurrence of a Change of Control, each Holder will have the right to require the Company to purchase all or a portion (in integral
multiples of $1,000) of such Holder’s Notes using immediately available funds pursuant to the offer described below (the “Change of Control Offer”), at a purchase price in cash equal to 101% of the principal amount thereof on
the date of purchase, plus accrued and unpaid interest and Additional Interest, if any, to the date of purchase. 
 (b) Within 30 days
following the date upon which the Change of Control occurred, the Company shall send, by registered first class mail, postage prepaid, a notice to each record Holder as shown on the register of Holders, with a copy to the Trustee, which notice shall
govern the terms of the Change of Control Offer. The notice to the Holders shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Change of Control Offer. Such notice shall state: 
 (1) that the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes tendered and not withdrawn
shall be accepted for payment; 
 (2) the purchase price (including the amount of accrued interest) and the purchase date
(which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed, other than as may be required by law) (the “Change of Control Payment Date”); 
 (3) that any Note not tendered shall continue to accrete in value and accrue interest; 
 (4) that, unless the Company defaults in making payment therefor, any Note accepted for payment pursuant to the Change of Control Offer
shall cease to accrete in value and accrue interest after the Change of Control Payment Date; 
 (5) that Holders electing to
have a Note purchased pursuant to a Change of Control Offer shall be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed, to the Paying Agent at the address
specified in the notice prior to the close of business on the third Business Day prior to the Change of Control Payment Date; 
 (6) that Holders shall be entitled to withdraw their election if the Paying Agent receives, not later than three (3) Business Days prior to the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting
forth the name of the Holder, the principal amount of the Notes the Holder delivered for purchase and a statement that such Holder is withdrawing its election to have such Notes purchased; 
 (7) that Holders whose Notes are purchased only in part shall be issued new Notes in a principal amount equal to the portion thereof not
purchased will be issued in the name of the Holder thereof upon cancellation of the original Note (or appropriate adjustments to the amount and beneficial interests in a Global Note will be made); provided that each Note purchased and each
new Note issued shall be in an original principal amount of $1,000 or integral multiples thereof; and 
 (8) the circumstances
and relevant facts regarding such Change of Control. 
  

 -48- 








 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 such notice to the extent necessary to comply with the procedures of the Depositary applicable to repurchases. 
 On or
before the Change of Control Payment Date, the Company shall (i) accept for payment Notes or portions thereof properly tendered pursuant to the Change of Control Offer, (ii) deposit with the Paying Agent U.S. Legal Tender sufficient to pay
the purchase price plus accrued interest, if any, of all Notes or portions thereof so tendered and (iii) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate
principal amount of Notes or portions thereof being purchased by the Company. The Paying Agent shall promptly mail to the Holders of Notes so tendered the purchase price for such Notes and the Company shall promptly issue and the Trustee shall
promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered; provided that each such new Note shall be in a principal amount
of $1,000 or an integral multiple thereof. Any Notes not so accepted shall be promptly mailed by the Company to the Holders thereof. For purposes of this Section 4.15, the Trustee shall act as the Paying Agent. 
 Any amounts remaining after the purchase of Notes pursuant to a Change of Control Offer will be returned by the Trustee to the Company. 
 Neither the Board of Directors of the Company nor the Trustee may waive the Company’s obligation to offer to purchase the Notes pursuant to this
Section 4.15. 
 The Company will comply with the requirements of 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 connection with the repurchase of Notes pursuant to a Change of Control Offer. To the extent the provisions of any securities laws or regulations conflict with the
provisions under this Section 4.15, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.15 by virtue thereof. 

Notwithstanding the above, the Company will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the
Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements of this Section 4.15 and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. 
 Notes (or portions thereof) purchased pursuant to a Change of Control Offer shall be cancelled and may not be reissued. 
 Section 4.16. Limitation on Asset Sales. The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale
unless: 
 (1) the Company or the applicable 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 assets sold or otherwise disposed; 
 (2) at least 75% of the
consideration received by the Company or the Restricted Subsidiary, as the case may be, from such Asset Sale is in the form of cash or Cash Equivalents or assets described in the following clause (3)(b) and is received at the time of such
disposition; provided that the amount of any liabilities (as shown on the most recent applicable balance sheet) of the Company or such Restricted Subsidiary (other than liabilities that are by their terms subordinated to the Notes) that are
assumed by the transferee of any such assets shall be deemed to be cash for purposes of this provision so long as the documents governing such liabilities provide that there is no further recourse to the Company or any of its Subsidiaries with
respect to such liabilities; and 
  

 -49- 








 (3) the Company shall apply, or cause such Restricted Subsidiary to apply, the Net Cash
Proceeds relating to such Asset Sale within 360 days of receipt thereof either: 
 (a) to repay Indebtedness under the Credit
Agreement and permanently reduce the commitments thereunder; 
 (b) to make an investment in property, plant, equipment or
other non-current assets that replace the properties and assets that were the subject of such Asset Sale or that will be used or useful in a Permitted Business (including expenditures for maintenance, repair or improvement of existing properties and
assets) or the acquisition of all of the Capital Stock of a Person engaged in a Permitted Business; or 
 (c) a combination of
repayment and investment permitted by the foregoing clauses (3)(a) and (3)(b). 
 Pending the final application of Net Cash
Proceeds, the Company may temporarily reduce revolving credit borrowings or invest such Net Cash Proceeds in Cash Equivalents. On the 361st day after an Asset Sale or such earlier date, if any, as the Board of Directors of the Company or of such
Restricted Subsidiary determines not to apply the Net Cash Proceeds relating to such Asset Sale as set forth in clauses (3)(a), (3)(b) or (3)(c) of the preceding paragraph (each, a “Net Proceeds Offer Trigger Date”), such
aggregate amount of Net Cash Proceeds which have not been applied on or before such Net Proceeds Offer Trigger Date as permitted in clauses (3)(a), (3)(b) and (3)(c) of the preceding paragraph (each a “Net Proceeds Offer
Amount”) shall be applied by the Company or such Restricted Subsidiary to make an offer to purchase (the “Net Proceeds Offer”) on a date (the “Net Proceeds Offer Payment Date”) not less than 30 nor more
than 45 days following the applicable Net Proceeds Offer Trigger Date, from all Holders, the maximum principal amount of Notes that may be purchased with the Net Proceeds Offer Amount at a price equal to 100% of the principal amount thereof, plus
accrued and unpaid interest and Additional Interest, if any, thereon to the date of purchase; provided, however, that if at any time any non-cash consideration received by the Company or any Restricted Subsidiary of the Company,
as the case may be, in connection with any Asset Sale is converted into or sold or otherwise disposed of for cash (other than interest received with respect to any such non-cash consideration), then such conversion or disposition shall be deemed to
constitute an Asset Sale hereunder on the date of such conversion or disposition, as the case may be, and the Net Cash Proceeds thereof shall be applied in accordance with this covenant. 
 The Company may defer any Net Proceeds Offer until there is an aggregate unutilized Net Proceeds Offer Amount equal to or in excess of $5.0 million
resulting from one or more Asset Sales in which case the accumulation of such amount shall constitute a Net Proceeds Offer Trigger Date (at which time, the entire unutilized Net Proceeds Offer Amount, and not just the amount in excess of $5.0
million, shall be applied as required pursuant to the immediately preceding paragraph). Upon the completion of each Net Proceeds Offer, the Net Proceeds Offer Amount will be reset at zero. 
 In the event of the transfer of substantially all (but not all) of the property and assets of the Company and its Restricted Subsidiaries as an entirety
to a Person in a transaction permitted under Section 5.01, which transaction does not constitute a Change of Control, the successor entity shall be deemed to have sold the properties and assets of the Company and its Restricted
Subsidiaries not so transferred for purposes of this covenant, and shall comply with the provisions of this covenant with respect to such deemed sale as if it constituted an Asset Sale. In addition, the Fair Market Value of such properties and
assets of the Company or its Restricted Subsidiaries deemed to be sold shall be deemed to be Net Cash Proceeds for purposes of this covenant. 
  

 -50- 








 Each notice of a Net Proceeds Offer shall be mailed first class, postage prepaid, to the record Holders
as shown on the register of Holders within 20 days following the Net Proceeds Offer Trigger Date, with a copy to the Trustee, and shall comply with the procedures set forth in this Indenture. Upon receiving notice of the Net Proceeds Offer, Holders
may elect to tender their Notes in whole or in part in integral multiples of $1,000 in exchange for cash. To the extent Holders properly tender Notes in an amount exceeding the Net Proceeds Offer Amount, Notes of tendering Holders will be purchased
on a pro rata basis (based on amounts tendered). A Net Proceeds Offer shall remain open for a period of 20 business days or such longer period as may be required by law. 
 The Company will comply with the requirements of 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 connection with the repurchase of Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any securities laws or regulations conflict with the “Asset Sale” provisions of this
Indenture, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the “Asset Sale” provisions of this Indenture by virtue of such compliance. 

Section 4.17. Limitation on Liens. The Company will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or
indirectly, create, incur, assume or permit or suffer to exist any Liens (other than Permitted Liens) of any kind against or upon any property or assets of the Company or any of its Restricted Subsidiaries whether owned on the Issue Date or acquired
after the Issue Date, or any proceeds therefrom, or assign or otherwise convey any right to receive income or profits therefrom (other than collateral assignments constituting Permitted Liens). 
 Section 4.18. Conduct of Business. The Company will not, and will not permit any of its Restricted Subsidiaries to, engage in any businesses other
than the Permitted Businesses. 
 Section 4.19. Limitation on Issuances and Sales of Capital Stock of Subsidiaries. The Company will
not permit or cause any of its Restricted Subsidiaries to issue or sell, any Capital Stock (other than to the Company or a Wholly Owned Restricted Subsidiary of the Company) or permit any Person (other than the Company or a Wholly-Owned Restricted
Subsidiary of the Company) to own or hold any Capital Stock of any Restricted Subsidiary of the Company (other than as required by applicable law); provided, however, that this provision shall not prohibit (1) any issuance or sale
if, immediately after giving effect thereto, such Restricted Subsidiary would no longer constitute a Restricted Subsidiary and any Investment in such Person remaining after giving effect to such issuance or sale would have been permitted to be made
under Section 4.10 if made on the date of such issuance or sale or (2) the sale of all of the Capital Stock of a Restricted Subsidiary in compliance with Section 4.16. 
 Section 4.20. Payments for Consent. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pay
or cause to be paid any consideration to or for the benefit of any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture, the Notes, or any of the Collateral Agreements unless such
consideration is offered to be paid or is paid to all Holders that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement. 
 Section 4.21. Impairment of Security Interest. Subject to the Intercreditor Agreement, neither the Company nor any of its Restricted Subsidiaries
will take or omit to take any action which would adversely affect or impair in any material respect the Liens in favor of the Collateral Agent with 

  

 -51- 








 
respect to the Collateral, except as otherwise permitted or required by the Collateral Agreements or this Indenture. Neither the Company nor any of its
Restricted Subsidiaries will enter into any agreement that requires the proceeds received from any sale of Collateral to be applied to repay, redeem, defease or otherwise acquire or retire any Indebtedness of any Person, other than as permitted by
this Indenture and the Collateral Agreements (including the Intercreditor Agreement). The Company shall, and shall cause each Guarantor to, at their sole cost and expense, execute and deliver all such agreements and instruments as the Collateral
Agent or the Trustee shall reasonably request to more fully or accurately describe the property intended to be Collateral or the obligations intended to be secured by the Collateral Agreements. The Company shall, and shall cause each Guarantor to,
at their sole cost and expense, file any such notice filings or other agreements or instruments as may be reasonably necessary or desirable under applicable law to perfect the Liens created by the Collateral Agreements at such times and at such
places as the Collateral Agent or the Trustee may reasonably request. 
 Section 4.22. Real Estate Mortgages and Filings. With respect
to any real property other than Oil and Gas Assets and Excluded Collateral (individually and collectively, the “Premises”) owned by the Company or a Domestic Restricted Subsidiary on the Issue Date with a Fair Market Value of
greater than $500,000 and with respect to any such property to be acquired by the Company or a Domestic Subsidiary after the Issue Date with a purchase price of greater than $500,000 (within 90 days of the acquisition thereof): 
 (1) the Company shall deliver to the Collateral Agent, as mortgagee, fully executed counterparts of Mortgages, duly executed by the
Company or the applicable Domestic Restricted Subsidiary, together with evidence of the completion (or satisfactory arrangements for the completion), of all recordings and filings of such Mortgage as may be necessary to create a valid, perfected
Lien, subject to Permitted Liens, against the properties purported to be covered thereby; 
 (2) the Company shall deliver to
the Collateral Agent mortgagee’s title insurance policies in favor of the Collateral Agent, as mortgagee for the ratable benefit of the Collateral Agent, the Trustee and the Holders in an amount equal to the lesser of (x) the aggregate
principal amount of the Notes and (y) 100% of the Fair Market Value of the Premises purported to be covered by the related Mortgage, insuring that title to such property is marketable and that the interests created by the Mortgage constitute
valid Liens thereon free and clear of all Liens, defects and encumbrances other than Permitted Liens together with such necessary endorsements, coinsurance and reinsurance; 
 (3) the Company shall deliver to the Collateral Agent, with respect to each of the covered Premises, the most recent survey of such
Premises, together with either (i) an updated survey certification in favor of the Trustee and the Collateral Agent from the applicable surveyor stating that, based on a visual inspection of the property and the knowledge of the surveyor, there
has been no change in the facts depicted in the survey or (ii) an affidavit from the Company and the Guarantors stating that there has been no change, sufficient for the title insurance company to remove all standard survey exceptions and issue
the endorsements reasonably required by the Collateral Agent; and 
 (4) the Company shall deliver to the Collateral Agent an
opinion from local counsel in each state where a Premises is located in covering the enforceability of the relevant Mortgages. 
  

 -52- 








 Section 4.23. Oil and Gas Mortgages and Filings. With respect to any Oil and Gas Assets owned by
the Company or a Domestic Restricted Subsidiary on the Issue Date or acquired by the Company or a Domestic Subsidiary after the Issue Date, excluding in all cases Excluded Collateral: 
 (1) the Company shall deliver to the Collateral Agent, as mortgagee, fully executed counterparts of Mortgages or amendments and
supplements to prior Mortgages, duly executed by the Company or the applicable Domestic Restricted Subsidiary in form and substance reasonably satisfactory to the Collateral Agent (together with evidence of the completion – or satisfactory
arrangements for the completion – of all recordings and filings of such instruments) as may be necessary to create a valid, perfected Lien (subject to no Liens other than Permitted Liens) on such Oil and Gas Assets; and 
 (2) the Company shall deliver to the Collateral Agent an opinion from local counsel in each state where such Oil and Gas Assets are
located, in form and substance reasonably satisfactory to the Collateral Agent and covering such matters as Collateral Agent may reasonably request, including without limitation, the enforceability of the relevant Mortgage, as it may be supplemented
or amended. 
 Each such Mortgage, amendment or supplement shall be delivered by the Company on or prior to the first Business Day of each January, April,
July or October (beginning with January 1, 2008) that occurs: 
 (i) after the acquisition of such Oil and Gas Assets by
the Company or a Domestic Restricted Subsidiary or 
 (ii) if such Oil and Gas Assets were previously Excluded Collateral but
have ceased to be Excluded Collateral, after such cessation, 
 provided that if, prior to such date, the Company or a Domestic Restricted Subsidiary
grants a Lien on such Oil and Gas Assets to secure First Priority Claims, such Mortgage, amendment or supplement must be delivered to the Collateral Agent at the same time as such grant to secure First Priority Claims. 
 Section 4.24. Leasehold Mortgages and Filings; Landlord Waivers. The Company and each of its Domestic Restricted Subsidiaries shall deliver
Mortgages with respect to the Company’s leasehold interests in the premises (the “Leased Premises”) occupied by the Company or such Domestic Restricted Subsidiary pursuant to leases which may be mortgaged by their terms or the
terms of the landlord consents (collectively, the “Leases,” and individually, a “Lease”). 
 Prior
to Issue Date or the effective date of any Lease, as applicable, the Company and such Subsidiaries shall provide to the Trustee all of the items described in clauses (2), (3) and (4) of Section 4.22 above and in addition shall
use their respective reasonable commercial efforts to obtain an agreement executed by the lessor under the Lease, whereby the lessor consents to the Mortgage and waives or subordinates its landlord Lien (whether granted by the instrument creating
the leasehold estate or by applicable law), if any, and which shall be entered into by the Collateral Agent. 
 Each of the Company and each
of its Domestic Restricted Subsidiaries that is a lessee of, or becomes a lessee of, real property, is, and will be, required to use commercially reasonable efforts to deliver to the Collateral Agent a landlord waiver, substantially in the form of
the exhibit form thereof to be attached to this Indenture, executed by the lessor of such real property; provided that in the case where such lease is a lease in existence on the Issue Date, the Company or its Domestic Restricted Subsidiary
that is the lessee thereunder shall have 90 days from the Issue Date to satisfy such requirement. 
 Section 4.25. Other Collateral.
Subject to the Intercreditor Agreement, with respect to any other assets or property (herein called “Other Collateral”) that are neither Excluded Collateral nor addressed in Section 4.22, 4.23 or 4.24 nor subject
to the Security Agreement and are owned by the Company or a Domestic Restricted Subsidiary on the Issue Date or acquired by the Company or a 

  

 -53- 








 
Domestic Subsidiary after the Issue Date, the Company or such Domestic Restricted Subsidiary will promptly grant Liens covering such Other Collateral to the
Collateral Agent pursuant to a document or instrument on reasonable commercial terms that contains provisions similar to those of the Security Agreement, if such Other Collateral is personal property, or provisions similar to those of the Mortgages
described in Section 4.22, if such Other Collateral is real property. 
 Section 4.26. Additional Interest. If Additional
Interest becomes payable by the Company pursuant to the Registration Rights Agreement, the Company shall deliver to the Trustee an Officers’ Certificate stating (i) the amount of Additional Interest due and payable, (ii) the Section
of the Registration Rights Agreement pursuant to which Additional Interest is due and payable and (iii) the date on which Additional Interest is payable. Unless and until a Trust Officer of the Trustee receives such an Officers’
Certificate, the Trustee may assume without inquiry that no Additional Interest is payable; provided that the failure of the Company to deliver to the Trustee such Officers’ Certificate shall not relieve the Company of its obligation to
pay any such Additional Interest when due and payable. 
 Section 4.27. Excess Cash Flow Offer. 
 (a) If the Company has Excess Cash Flow (i) for the period from the Issue Date to December 31, 2007 (the “Initial Period”) and
(ii) subsequent to the Initial Period, for each of the fiscal years ending on December 31, 2008 and December 31, 2009 (the “Second Period”) then the Company shall apply an amount (the “Excess Cash Flow Offer
Amount”) equal to 100% of such Excess Cash Flow for such period to make an offer to the Holders to repurchase all or a portion (in integral multiples of $1,000) of their Notes with an aggregate repurchase price in cash equal to the Excess
Cash Flow Offer Amount pursuant to and subject to the conditions contained in this Indenture (an “Excess Cash Flow Offer”). If the Company has Excess Cash Flow subsequent to the Second Period, for each of the fiscal years ending on
December 31, 2010 and December 31, 2011 (the “Third Period” and, together with the Initial Period and the Second Period, the “Periods”) then the Company shall apply an Excess Cash Flow Offer Amount equal to 50%
of such Excess Cash Flow for such period to make an Excess Cash Flow Offer. 
 (b) Each Excess Cash Flow Offer will remain open for a period
of twenty (20) Business Days and no longer, unless a longer period is required by law (the “Excess Cash Flow Offer Period”). Promptly after the termination of the Excess Cash Flow Offer Period, the Company will purchase and
mail or deliver payment (up to the Excess Cash Flow Offer Amount) for the Notes or portions thereof tendered, pro rata (based on amounts tendered) or by such other method as may be required by law, or, if less than the Excess Cash Flow
Offer Amount has been tendered, all Notes tendered pursuant to the Excess Cash Flow Offer. 
 (c) If the Company is required to make an
Excess Cash Flow Offer pursuant to clause (a) of this Section 4.27, the Company must send within 90 days after the end of such period, by registered first-class mail, an offer to each Holder, with a copy to the Trustee, which
offer shall govern the terms of the Excess Cash Flow Offer. Such offer shall state: 
 (i) the purchase price; 
 (ii) the Excess Cash Flow Offer Period; 
 (iii) that the Company is making an Excess Cash Flow Offer; 
 (iv) that any Note not tendered
will continue to accrue interest, if applicable; 
  

 -54- 








 (v) that unless the Company defaults on the payment of the purchase price, any Notes
accepted for payment pursuant to the Excess Cash Flow Offer will cease to accrue interest after the Excess Cash Flow Offer Period; 
 (vi) the repurchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is mailed, other than as may be required by law (the “Excess Cash Flow Offer Payment Date”); and 

(vii) the address of the Paying Agent and the procedures that a Holder of Notes must follow to accept the Excess Cash Flow Offer or
withdraw such acceptance in accordance with this Section 4.27. 
 (d) Holders electing to have a Note purchased pursuant to an
Excess Cash Flow Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed, to the Paying Agent at the address specified in the notice prior to the close
of business on the third business day prior to the Excess Cash Flow Offer Payment Date. If only a portion of a Note is purchased pursuant to an Excess Cash Flow Offer, a new Note in a principal amount equal to the portion thereof not purchased will
be issued in the name of the Holder thereof upon cancellation of the original Note (or appropriate adjustments to the amount and beneficial interests in a Global Note will be made). Notes (or portions thereof) purchased pursuant to an Excess Cash
Flow Offer will be cancelled and cannot be reissued. 
 (e) Promptly after the termination of the Excess Cash Flow Offer Period, the Company
will, to the extent lawful: 
 (i) accept for payment all Notes or portions thereof properly tendered pursuant to the Excess
Cash Flow Offer; 
 (ii) deposit with the Paying Agent in cash an amount equal to 100% of the aggregate principal amount
thereof, plus accrued but unpaid interest, if any, thereon to the Excess Cash Flow Offer Payment Date in respect of all Notes or portions thereof so tendered; provided that the aggregate amount so deposited shall not exceed the Excess Cash Flow
Offer Amount; and 
 (iii) deliver or cause to be delivered to the Trustee the Notes so accepted together with an
Officers’ Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by the Company. 
 (f) With
respect to each Excess Cash Flow Offer, the Company shall be entitled to reduce the applicable Excess Cash Flow Offer Amount with respect thereto by the aggregate repurchase price of any Notes theretofore repurchased by the Company in the open
market (to the extent such amount has not previously reduced any Excess Cash Flow Offer Amount). 
 (g) In each Excess Cash Flow Offer, the
Company will be required to repurchase Notes validly tendered in response to such Excess Cash Flow Offer at a purchase price in cash equal to 101% of their principal amount, plus accrued but unpaid interest and Additional Interest, if any, thereon
to the Excess Cash Flow Offer Payment Date, in accordance with the procedures (including proration in the event of oversubscription) set forth in this Indenture. The Company will not be required to make an Excess Cash Flow Offer if the Excess Cash
Flow for any Period is less than $2.5 million. 
  

 -55- 








 (h) If the aggregate repurchase price of Notes tendered pursuant to any Excess Cash Flow Offer is less
than the applicable Excess Cash Flow Offer Amount, the Company may, subject to the other provisions of this Indenture, use any such Excess Cash Flow for any other lawful purpose. 
 (i) If an Excess Cash Flow Offer is made, there can be no assurance that the Company will have available funds sufficient to pay the Excess Cash Flow
purchase price for all the Notes that might be delivered by Holders seeking to accept the Excess Cash Flow Offer. 
 Notwithstanding the
foregoing, the repurchase of Notes by the Company pursuant to any Excess Cash Flow Offer shall not be required if it would breach any covenant under the Credit Agreement that prohibits the consummation of the applicable Excess Cash Flow Offer and
shall be limited to amounts as provided under the Credit Agreement. 
 The Company will comply with the requirements of 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 connection with the repurchase of Notes pursuant to an Excess Cash Flow Offer. To the extent that the provisions of any
securities laws or regulations conflict with this Section 4.27, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.27 by
virtue thereof.

 Section 4.33. Obligation to Hedge. 
 Within 60 days after receipt of each annual Reserve Report with respect to the proved oil and gas reserves of the Company and its Restricted
Subsidiaries, and within a reasonable time after each other determination that such proved oil and gas reserves have increased by a material amount, the Company will enter into, or will cause its Restricted Subsidiaries to enter into, and will
maintain in effect, one or more hedging agreements that in the aggregate fix prices, fix prices within a range, or fix minimum prices for at least 70% of the anticipated proved developed producing production of oil and gas from such reserves during
each of the then next following 12 calendar months. As used in this paragraph, “hedging agreements” means:

swap contracts, collar contracts, floor contracts, and other similar derivative contracts for notional quantities of oil or gas; 
  

 -57- 








 (2) contracts for the sale of actual oil and gas production; and 
 (3) contracts on a commodities exchange 
 that provide for fixed prices, a fixed range of prices, or floor prices, in each case with the purpose and effect of protecting the Company and its Restricted Subsidiaries against fluctuations in the prices of oil or
gas and not for purposes of speculation. 
 Section 4.34. No Amendment to Subordination Provision. 
 Without the consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding, the Company will not amend, modify

payment of interest on any Convertible Subordinated Notes; 
 (2) increase the principal of, advance the final maturity date
of or shorten the Weighted Average Life to Maturity of any Convertible Subordinated Notes; 
 (3) alter the redemption

 Section 5.01. Merger, Consolidation and Sale of Assets. The Company
will not, in a single transaction or series of related transactions, consolidate or merge with or into any Person, or sell, assign, transfer, lease, convey or otherwise dispose of (or cause or permit any Restricted Subsidiary of the Company to sell,
assign, transfer, lease, convey or otherwise dispose of) all or substantially all of the Company’s assets (determined on a consolidated basis for the Company and the Company’s Restricted Subsidiaries) whether as an entirety or
substantially as an entirety to any Person unless: 
 (1) either: 
 (a) the Company shall be the surviving or continuing corporation; or 
 (b) the Person (if other than the Company) formed by such consolidation or into which the Company is merged or the Person which acquires
by sale, assignment, transfer, lease, conveyance or other disposition the properties and assets of the Company and of the Company’s Restricted Subsidiaries substantially as an entirety (the “Surviving Entity”): 
 (x) shall be a corporation organized and validly existing under the laws of the United States or any State thereof or the District of
Columbia; and 
 (y) shall expressly assume, (i) by supplemental indenture (in form and substance reasonably
satisfactory to the Trustee), executed and delivered to the Trustee and the Collateral Agent, the due and punctual payment of the principal of, and premium, if any, and interest and Additional Interest, if any, on, all of the Notes and the
performance of every covenant of the Notes, this Indenture and the Registration Rights Agreement on the part of the Company to be performed or observed thereunder and (ii) by amendment, supplement or other instrument (in form and substance
reasonably satisfactory to the Trustee and the Collateral Agent), executed and delivered to the Trustee, all obligations of the Company under the Collateral Agreements, and in connection therewith shall cause such instruments to be filed and
recorded in such jurisdictions and take such other actions as may be required by applicable law to perfect or continue the perfection of the Lien created under the Collateral Agreements on the Collateral owned by or transferred to the surviving
entity; 
 (2) immediately after giving effect to such transaction and the assumption contemplated by clause
(1)(b)(y) above (including giving effect to any Indebtedness and Acquired Indebtedness incurred or anticipated to be incurred in connection with or in respect of such transaction), the Company or such Surviving Entity, as the case may be,
(a) shall have a Consolidated Net Worth at least equal to the Consolidated Net Worth of the Company immediately prior to such transaction and (b) shall be able to incur at least $1.00 of additional Indebtedness (other than Permitted
Indebtedness) in compliance with Section 4.12;

transaction), no Default or Event of Default shall have occurred or be continuing; and 
  

 -59- 








 (4) the Company or the Surviving Entity shall have delivered to the Trustee an
Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition and, if a supplemental indenture is required in connection with such transaction,
such supplemental indenture comply with the applicable provisions of this Indenture and that all conditions precedent in this Indenture relating to such transaction have been satisfied. 
 For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise, in a single transaction or series of transactions) of all or
substantially all of the properties or assets of one or more Restricted Subsidiaries of the Company, the Capital Stock of which constitutes all or substantially all of the properties and assets of the Company, shall be deemed to be the transfer of
all or substantially all of the properties and assets of the Company. 
 Each Guarantor (other than any Guarantor whose Guarantee is to be
released in accordance with the terms of the Guarantee and this Indenture in connection with any transaction complying with the provisions of this covenant and Section 4.16) will not, and the Company will not cause or permit any
Guarantor to, consolidate with or merge with or into any Person, other than the Company or any other Guarantor unless: 
 (1)
the entity formed by or surviving any such consolidation or merger (if other than the Guarantor) or to which such sale, lease, conveyance or other disposition shall have been made is a corporation, limited partnership or limited liability company
organized and existing under the laws of the United States or any State thereof or the District of Columbia; 
 (2) such
entity assumes (a) by supplemental indenture (in form and substance reasonably satisfactory to the Trustee), executed and delivered to the Trustee, all of the obligations of the Guarantor under the Guarantee and the performance of every
covenant of the Guarantee, this Indenture and the Registration Rights Agreement and (b) by amendment, supplement or other instrument (in form and substance satisfactory to the Trustee and the Collateral Agent) executed and delivered to the
Trustee and the Collateral Agent, all obligations of the Guarantor under the Collateral Agreements and in connection therewith shall cause such instruments to be filed and recorded in such jurisdictions and take such other actions as may be required
by applicable law to perfect or continue the perfection of the Lien created under the Collateral Agreements on the Collateral owned by or transferred to the surviving entity; 
 (3) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing; and

 (4) such entity shall have delivered to the Trustee and Officer’s Certificate and an Opinion of Counsel, each stating
that such consolidation or merger complies with this Indenture. 
 Any merger or consolidation of (i) a Guarantor with and into the
Company (with the Company being the surviving entity) or another Guarantor or (ii) a Guarantor or the Company with an Affiliate organized solely for the purpose of reincorporating or (or, except with respect to the Company, reorganizing) such
Guarantor or the Company in another jurisdiction in the United States or any state thereof or the District of Columbia need only comply with: 
 (A) clause (4) of the first paragraph of this covenant; and 
  

 -60- 








 (B) (x) in the case of a merger or consolidation involving the Company as described
in clause (ii), clause (1)(b)(y) of the first paragraph of this covenant and (y) in the case of a merger or consolidation involving the Guarantor as described in clause (ii), clause (2) of the immediately preceding paragraph.

 Section 5.02. Successor Corporation Substituted. Upon any consolidation, combination or merger or any transfer of all or
substantially all of the assets of the Company in accordance with the foregoing, in which the Company is not surviving or the continuing corporation, the successor Person formed by such consolidation or into which the Company is merged or to which
such conveyance, lease or transfer is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture and the Notes with the same effect as if such surviving entity had been named as such,
provided, however, that the predecessor Company shall not be relieved from the obligation to pay the principal of and interest on the Notes except in the case of a sale of all of the Company’s assets in a transaction that is
subject to, and that complies with the provisions of, Section 5.01 hereof. 
 ARTICLE SIX 
 Default and Remedies 
 Section 6.01.
Events of Default. Each of the following is an “Event of Default”: 
 (1) the failure to pay interest
and Additional Interest, if any, on any Notes when the same becomes due and payable and the default continues for a period of 30 days; 
 (2) the failure to pay the principal of or premium, if any, on any Notes, when such principal becomes due and payable, at maturity, upon redemption or otherwise (including the failure to make a payment to purchase
Notes tendered pursuant to a Change of Control Offer or a Net Proceeds Offer); 
 (3) a default in the observance or
performance of any other covenant or agreement contained in this Indenture (other than the payment of the principal of, or premium, if any, or interest and Additional Interest, if any, on any Note) or any Collateral Agreement which default continues
for a period of 30 days after the Company receives written notice specifying the default (and demanding that such default be remedied) from the Trustee or the Holders of at least 25% of the outstanding principal amount of the Notes (except in the
case of a default with respect to Section 5.01, which will constitute an Event of Default with such notice requirement but without such passage of time requirement); 
 (4) the failure to pay at final maturity (after giving effect to any applicable grace periods and any extensions thereof) the principal
amount of any Indebtedness of the Company or any Restricted Subsidiary of the Company, or the acceleration of the final stated maturity of any such Indebtedness (which acceleration is not rescinded, annulled or otherwise cured within 20 days from
the date of acceleration) if the aggregate principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness in default for failure to pay principal at final maturity or which has been accelerated (in each case
with respect to which the 20-day period described above has elapsed), aggregates $5.0 million or more at any time; 
  

 -61- 








 (5) one or more judgments in an aggregate amount in excess of $5.0 million shall have
been rendered against the Company or any of its Restricted Subsidiaries (other than any judgment as to which a reputable and solvent third party insurer has accepted full coverage) and such judgments remain undischarged, unpaid or unstayed for a
period of 60 days after such judgment or judgments become final and non-appealable; 
 (6) the Company or any Significant
Subsidiary (A) commences a voluntary case or proceeding under any Bankruptcy Code with respect to itself, (B) consents to the entry of a judgment, decree or order for relief against it in an involuntary case or proceeding under any
Bankruptcy Code, (C) consents to the appointment of a Custodian of it or for substantially all of its property, (D) consents to or acquiesces in the institution of a bankruptcy or an insolvency proceeding against it, (E) makes a
general assignment for the benefit of its creditors, or (F) takes any corporate action to authorize or effect any of the foregoing; 
 (7) a court of competent jurisdiction enters a judgment, decree or order for relief in respect of the Company or any Significant Subsidiary in an involuntary case or proceeding under any Bankruptcy Code, which shall
(A) approve as properly filed a petition seeking reorganization, arrangement, adjustment or composition in respect of the Company or any Significant Subsidiary, (B) appoint a Custodian of the Company or any Significant Subsidiary or for
substantially all of its property or (C) order the winding-up or liquidation of its affairs; and such judgment, decree or order shall remain unstayed and in effect for a period of sixty (60) consecutive days; 
 (8) any Collateral Agreement at any time for any reason shall cease to be in full force and effect in all material respects, or ceases to
give the Collateral Agent the Liens, rights, powers and privileges purported to be created thereby, superior to and prior to the rights of all third Persons other than the holders of Permitted Liens and subject to no other Liens except as expressly
permitted by the applicable Collateral Agreement or this Indenture; 
 (9) the Company or any of the Guarantors, directly or
indirectly, contest in any manner the effectiveness, validity, binding nature or enforceability of any Collateral Agreement; or 
 (10) the Guarantee of any Significant Subsidiary ceases to be in full force and effect or is declared to be null and void and unenforceable or is found to be invalid or any Guarantor denies its liability under its Guarantee (other than by
reason of release of a Guarantor in accordance with the terms of this Indenture). 
 Section 6.02. Acceleration. 
 (a) If an Event of Default (other than an Event of Default specified in Section 6.01, clause (6) or (7) above with respect to the
Company) shall occur and be continuing and has not been waived, the Trustee or the Holders of at least 25% in principal amount of outstanding Notes may declare the principal of, and premium, if any, and accrued interest and Additional Interest, if
any, on, all the Notes to be due and payable by notice in writing to the Company and the Trustee specifying the Event of Default and that it is a “notice of acceleration”, and the same shall become immediately due and payable. 

(b) If an Event of Default specified in Section 6.01, clause (6) or (7) above with respect to the Company occurs and is
continuing, then all unpaid principal of, and premium, if any, and accrued and unpaid interest and Additional Interest, if any, on all of the outstanding Notes shall ipso facto become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holder. 
  

 -62- 








 (c) At any time after a declaration of acceleration with respect to the Notes as described in the
preceding paragraphs, the Holders of a majority in principal amount of the Notes may rescind and cancel such declaration and its consequences: (1) if the rescission would not conflict with any judgment or decree; (2) if all existing Events
of Default have been cured or waived except nonpayment of principal, premium, if any, interest or Additional Interest, if any, that has become due solely because of the acceleration; (3) to the extent the payment of such interest is lawful,
interest on overdue installments of interest and overdue principal and premium, if any, and Additional Interest, if any, which has become due otherwise than by such declaration of acceleration, has been paid; (4) if the Company has paid each of
the Trustee and the Collateral Agent its compensation and reimbursed each of the Trustee and the Collateral Agent for its expenses, disbursements and its advances; and (5) in the event of the cure or waiver of an Event of Default of the type
described in Section 6.01, clause (6) or (7) of the description above of Events of Default, the Trustee shall have received an Officers’ Certificate and an Opinion of Counsel that such Event of Default has been cured or
waived. No such rescission shall affect any subsequent Default or impair any right consequent thereto. 
 Section 6.03. Other
Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of, premium, if any, or interest on the Notes or to enforce the
performance of any provision of the Notes, this Indenture, any Collateral Agreement or any Guarantee. 
 The Trustee or the Collateral Agent
may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee, the Collateral Agent or any Holder in exercising any right or remedy accruing upon an Event
of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law. 
 Section 6.04. Waiver of Past Defaults. Subject to Sections 2.09, 6.07 and 9.02, the Holders of a majority in principal amount
of the Notes may waive any existing Default or Event of Default, and its consequences, except (other than as provided in Section 6.02(c)) a default in the payment of the principal of or premium, if any, or interest or Additional
Interest, if any, on, any Notes or in respect of a covenant or provision which under this Indenture cannot be modified or amended without the consent of the Holder of each Note then outstanding. When a Default or Event of Default is waived, it is
cured and ceases to exist and is deemed to have been cured and not to have occurred, and any Event of Default arising therefrom shall be deemed to have been cured and not to have occurred for every purpose of this Indenture, the Notes and the
Collateral Agreements, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. 
 Section 6.05. Control by Majority. Subject to Section 2.09, the Intercreditor Agreement and applicable law, the Holders of a majority in aggregate principal amount of the then outstanding Notes have
the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or the Collateral Agent, as the case may be, or exercising any trust or power conferred on the Trustee or the Collateral
Agent, as the case may be, including, without limitation, any remedies provided for in Section 6.03. Subject to Section 7.01 and 7.02(f), however, the Trustee or the Collateral Agent, as the case may be, may refuse to
follow any direction (which direction, if sent to the Trustee or the Collateral Agent, as the case may be, shall be in writing) that the Trustee or the Collateral Agent, as the case may be, reasonably believes conflicts with any applicable law, this
Indenture, the Notes, the Guarantees or the Collateral Agreements, that the Trustee or the 

  

 -63- 








 
Collateral Agent, as the case may be, determines may be unduly prejudicial to the rights of another Holder, or that may subject the Trustee or the Collateral
Agent, as the case may be, to personal liability; provided that the Trustee or the Collateral Agent, as the case may be, may take any other action deemed proper by the Trustee or the Collateral Agent, as the case may be, which is not
inconsistent with such direction (which direction, if sent to the Trustee or the Collateral Agent, as the case may be, shall be in writing). 
 Section 6.06. Limitation on Suits. A Holder may not pursue any remedy with respect to this Indenture or the Notes unless: 
 (1) the Holder gives to the Trustee written notice of a continuing Event of Default; 
 (2)
subject to Section 2.09, Holders of at least 25% in principal amount of the outstanding Notes make a written request to the Trustee to institute proceedings in respect of that Event of Default; 
 (3) such Holders offer to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense to be incurred in
compliance with such request; 
 (4) the Trustee does not comply with the request within sixty (60) days after receipt of
the request and the offer and, if requested, the provision of indemnity; and 
 (5) during such sixty (60) day period the
Holders of a majority in principal amount of the outstanding Notes do not give the Trustee a written direction which, in the opinion of the Trustee, is inconsistent with the request. 
 The foregoing limitations shall not apply to a suit instituted by a Holder for the enforcement of the payment of principal of, premium, if any, or
interest on such Note on or after the respective due dates set forth in such Note (including upon acceleration thereof) or the institution of any proceeding with respect to this Indenture or any remedy hereunder, including without limitation
acceleration, by the Holders of a majority in principal amount of outstanding Notes; provided that upon institution of any proceeding or exercise of any remedy, such Holders provide the Trustee with prompt notice thereof. 
 A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over such other Holder. 

Section 6.07. Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive
payment of principal of, premium, if any, and interest on a Note, on or after the respective due dates expressed in such Note, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or
affected without the consent of such Holder. 
 Section 6.08. Collection Suit by Trustee or Collateral Agent. If an Event of Default
in payment of principal of, premium, if any, or interest specified in Section 6.01(1) or (2) occurs and is continuing, subject to the Intercreditor Agreement, the Trustee and the Collateral Agent may recover judgment
(i) in its own name and (ii)(x) in the case of the Trustee, as trustee of an express trust or (y) in the case of the Collateral Agent, as collateral agent on behalf of each of the Holders, in each case against the Company or any other
obligor on the Notes for the whole amount of principal, premium, if any, and accrued interest remaining unpaid, together with interest on overdue principal and, to the extent that payment of such interest is lawful, interest on overdue installments
of interest at the rate set forth in 

  

 -64- 








 
Section 4.01 and 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, the Collateral Agent and their respective agents and counsel and any other amounts due the Trustee under the Collateral Agreements and Section 7.07 hereof. 
 Section 6.09. Trustee May File Proofs of Claim. The Trustee and the Collateral Agent are authorized to file such proofs of claim and other papers
or documents as may be necessary or advisable in order to have the claims of the Trustee or the Collateral Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, the Collateral Agent, their
respective agents and counsel) and the Holders allowed in any judicial proceedings relating to the Company or any other obligor upon the Notes, any of their respective creditors or any of their respective property and, subject to the Intercreditor
Agreement, shall be entitled and empowered to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same, and any Custodian in any such judicial proceedings is hereby authorized by each
Holder to make such payments to the Trustee or Collateral Agent and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee or Collateral Agent any amount due to it for the
reasonable compensation, expenses, taxes, disbursements and advances of the Trustee, the Collateral Agent, their respective agents and counsel, and any other amounts due any such Person under the Collateral Agreements and Section 7.07.
The Company’ payment obligations under this Section 6.09 shall be secured in accordance with the provisions of Section 7.07. Nothing herein contained shall be deemed to authorize the Trustee or Collateral Agent to
authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee or the Collateral Agent, as
the case may be, to vote in respect of the claim of any Holder in any such proceeding. 
 Section 6.10. Priorities. If the Trustee
collects any money or property pursuant to this Article Six, it shall pay out the money in the following order subject to the Intercreditor Agreement: 
 First: to the Trustee, the Collateral Agent, the Paying Agent and the Registrar for amounts due under Section 7.07
(including payment of all compensation expense, all liabilities incurred and all advances made by the Trustee or the Collateral Agent, as the case may be, and the costs and expenses of collection); 
 Second: if the Holders are forced to proceed against the Company directly without the Trustee or the Collateral Agent, to Holders
for their collection costs; 
 Third: to Holders for amounts due and unpaid on the Notes for principal, premium, if
any, and interest ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest respectively; and 
 Fourth: to the Company as a court of competent jurisdiction may direct. 
 The Trustee, upon prior written notice to the Company, may fix a record date and payment date for any payment to Holders pursuant to this
Section 6.10. 
 Section 6.11. Undertaking for Costs. All parties to this Indenture agree, and each Holder by its
acceptance of its Note shall be deemed to have agreed, that in any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee or the Collateral Agent, as the case may be, for any action taken or omitted
by it as Trustee or the Collateral Agent, as the case may be, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable 

  

 -65- 








 
attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by
the party litigant. This Section 6.11 does not apply to a suit by the Trustee or the Collateral Agent, as the case may be, a suit by a Holder pursuant to Section 6.06, or a suit by a Holder or Holders of more than 10% in
principal amount of the outstanding Notes. 
 Section 6.12. Restoration of Rights and Remedies. If the Trustee, the Collateral Agent
or any Holder has instituted any proceedings to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee, the Collateral Agent or to such
Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee, the Collateral Agent and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all
rights and remedies of the Trustee, the Collateral Agent and the Holders shall continue as though no such proceeding has been instituted. 
 Section 6.13. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.07, 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 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 6.14. Delay or Omission not Waiver. No delay or omission of the Trustee or the Collateral Agent 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 in 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. 
 ARTICLE SEVEN 
 Trustee 
 Section 7.01. Duties of Trustee. The duties and responsibilities of the Trustee shall be as provided by the TIA and as set forth herein or in any Collateral Agreement. All provisions of this Article
Seven applicable to the Trustee shall also apply to the Collateral Agent. 
 (a) If an Event of Default has occurred and is continuing,
the Trustee shall exercise such rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise thereof as a prudent person would exercise or use under the circumstances in the conduct of his or her own
affairs. 
 (b) Except during the continuance of an Event of Default: 
 (1) the duties of the Trustee shall be determined solely by the express provisions of this Indenture and the TIA, and the Trustee need
perform only those duties as are specifically set forth in this Indenture and no covenants or obligations shall be implied in or read into this Indenture against the Trustee; and 
  

 -66- 








 (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the
truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; provided, however, in case of any such
certificates or opinions furnished to the Trustee which by the provisions hereof are 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
need not confirm or investigate the accuracy of mathematical calculation or other facts stated herein. 
 (c) Notwithstanding anything to the
contrary herein contained, the Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: 
 (1) this paragraph does not limit the effect of paragraph (b) of this Section 7.01; 
 (2) the Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer, unless it is proved that the Trustee
was negligent in ascertaining the pertinent facts; and 
 (3) the Trustee shall not be liable with respect to any action it
takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05. 
 Sections
7.01(c)(1), (2) and (3) shall be in lieu of Section 315(d)(1), 315(d)(2) and 315(d)(3) of the TIA and such Sections 315(d)(1), 315(d)(2) and 315(d)(3) are herein expressly excluded form this Indenture,
as permitted by the TIA. 
 (d) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur
any liability or expense. The Trustee shall be under no obligation to exercise any of its rights or powers under this Indenture or the Collateral Agreements at the request of any Holders unless such Holder has offered to the Trustee security and
indemnity satisfactory to the Trustee against such risk, liability or expense is not reasonably assured to it. 
 (e) Whether or not therein
expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b), (c) and (d) of this Section 7.01. 
 (f) The Trustee shall not be liable for interest on any money or assets received by it except as the Trustee may agree in writing with the Company. Money

consequential losses or damages of any kind whatsoever, including but not limited to lost profits, whether or not foreseeable, even if the Trustee, the Paying Agent or the Registrar has been advised of the possibility thereof and regardless of the
form of action in which such damages are sought. 
 (h) The Trustee shall not be liable for the failure to perform its duties and obligations
hereunder to the extent such failure is directly caused by the failure of the Company to perform its obligations hereunder.

 (b) Before the Trustee acts or refrains from acting, it may consult with counsel and may require an Officers’
Certificate or an Opinion of Counsel, or both, which shall conform to Sections 11.04 and 11.05. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or

good faith and in reliance thereon. 
 (c) The Trustee may act through its attorneys and agents and shall not be responsible for the
misconduct or negligence of any agent appointed with due care and in good faith.

document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled, upon
reasonable notice to the Company, to examine the books, records and premises of the Company, personally or by agent or attorney and to consult with the officers and representatives of the Company, including the Company’s accountants and
attorneys at the sole cost of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation. Except as expressly stated herein to the contrary, in no event shall the Trustee have any
responsibility to ascertain whether there has been compliance with any of the covenants or provisions of Articles Four or Five hereof. 
 (f)
Neither the Trustee nor the Collateral Agent, as the case may be, will be under any obligation to exercise any of the rights or powers vested in it by this Indenture or any Collateral Agreement at the request, order or direction of any of the
Holders of any Person pursuant to the provisions of this Indenture unless such Holders or any Person shall have offered to the Trustee or the Collateral Agent, as the case may be, indemnity satisfactory to the Trustee or Collateral Agent, as the
case may be, against the costs, expenses and liabilities which may be incurred by it in compliance with such request, order or direction. 
 (g) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder. 
 (h) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company shall be sufficient if signed by an Officer of the Company and any resolution of the Board of Directors shall be
sufficient if evidenced by a copy of such resolution certified by an Officer of the Company to have been duly adopted and in full force and effect on the date hereof. 
  

 -68-

directly or by or through agents or attorneys and shall not be responsible for any willful misconduct or negligence on the part of any agent or attorney appointed with due care and in good faith by it hereunder. 
 (j) The Trustee shall not be liable for any action taken, suffered or omitted to be taken by it in good faith and reasonably believed by it to be
authorized or within the discretion, rights or powers conferred upon it by this Indenture. 
 (k) The Trustee shall not be deemed to have
notice or be charged with knowledge of any Default or Event of Default unless the Trust Officer or the Trustee shall have received from the Company, any Guarantor or any other obligor upon the Notes or from any Holder written notice thereof at its
address set forth in Section 11.02 hereof, and such notice references the Notes and this Indenture. 
 (l) The rights,
privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder (including without
limitation as Collateral Agent hereunder and under the Collateral Agreements), and each agent, custodian and other Person employed to act hereunder. 
 (m) The Trustee may request that the Company deliver an Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this
Indenture, which Officers’ Certificate may be signed by any persons authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded. 

(n) The permissive right of the Trustee to take any action under this Indenture or any Collateral Agreements shall not be construed as a duty to so
act. 
 Section 7.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or
pledgee of Notes and may otherwise deal with the Company, any Subsidiary of the Company or their respective Affiliates with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee must
comply with Sections 7.10 and 7.11 of this Indenture, and the Trustee is subject to TIA Sections 310(b) and 311. 
 Section
7.04. Trustee’s Disclaimer. The Trustee makes no representation as to the validity, adequacy or sufficiency of this Indenture, the Notes, or the Collateral Agreements, and it shall not be accountable for the Company’s use of the
proceeds from the Notes, and it shall not be responsible for any statement of the Company in this Indenture, the Notes, the Collateral Agreements or any other documents connected with the issuance of the Notes other than the Trustee’s
certificate of authentication, which shall be taken as the statement of Company, and the Trustee assumes no responsibility for their correctness. 
 Beyond the exercise of reasonable care in the custody thereof and the fulfillment of its obligations under this Indenture and the Collateral Agreements, the Trustee shall have no duty as to any Collateral in its possession or control or in
the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto. The Trustee shall be deemed to have exercised reasonable care in the custody of the
Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property. 
  

 -69- 








 The Trustee makes no representations as to and shall not be responsible for the existence, genuineness,
value, sufficiency or condition of any of the Collateral or as to the security afforded or intended to be afforded thereby, hereby or by any Collateral Agreement, or for the validity, perfection, priority or enforceability of the Liens or security
interests in any of the Collateral created or intended to be created by any of the Collateral Agreements, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder, except to the extent such action or
omission constitutes gross negligence or willful misconduct on the part of the Trustee, for the validity or sufficiency of the Collateral, any Collateral Agreements or any agreement or assignment contained in any thereof, for the validity of the
title of the Company or any Guarantor to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral. The Trustee shall have no duty
to ascertain or inquire as to the performance or observance of any of the terms of this Indenture or any other Collateral Agreement by the Company or any other Person that is a party thereto or bound thereby. The Trustee shall have no duty to file
financing statements. 
 Section 7.05. Notice of Default. If a Default or an Event of Default occurs and is continuing and if a Trust
Officer has actual knowledge or has received written notice from the Company or any Holder, the Trustee shall mail to each Holder, with a copy to the Company, notice of the Default or Event of Default within 30 days thereof unless such Default or
Event of Default shall have been cured or waived before the giving of such notice. Except in the case of a Default or an Event of Default in payment of principal of, premium, if any, or interest on, any Note, including an accelerated payment and the
failure to make payment on the Change of Control Payment Date pursuant to a Change of Control Offer and, except in the case of a failure to comply with Article Five, the Trustee may withhold the notice if and so long as its Board of
Directors, the executive committee of its Board of Directors or a committee of its directors and/or Trust Officers in good faith determines that withholding the notice is in the interest of the Holders. 
 Section 7.06. Reports by Trustee to Holders. Within 60 days after each October 1, beginning with October 1, 2008, the Trustee shall, to
the extent that any of the events described in TIA Section 313(a) occurred within the previous twelve months, but not otherwise, mail to each Holder a brief report dated as of such date that complies with TIA Section 313(a). The Trustee
also shall comply with TIA Sections 313(b) and (c). 
 A copy of each report at the time of its mailing to Holders shall be mailed to the
Company and filed by the Trustee with the Commission and each stock exchange or market, if any, on which the Notes are listed or quoted. 
 The Company shall promptly notify the Trustee if the Notes become listed, quoted on or delisted from any stock exchange or market and the Trustee shall comply with TIA Section 313(d). 
 Section 7.07. Compensation and Indemnity. The Company shall pay to the Trustee, the Collateral Agent, the Paying Agent and the Registrar (each an
“Indemnified Party”) from time to time compensation for their respective services as Trustee, Collateral Agent, Paying Agent or Registrar, as the case may be, as the Trustee, Collateral Agent and the Company shall have agreed. The
Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse each Indemnified Party upon request for all reasonable out-of-pocket expenses, disbursements and advances
incurred or made by it in connection with the performance of its duties under, as the case may be, this Indenture or the Collateral Agreements. Such expenses, disbursements and advances shall include the reasonable fees, expenses, disbursements and
advances of each of such Indemnified Party’s agents and counsel. 
  

 -70- 








 The Company and the Guarantors, jointly and severally, hereby indemnify each Indemnified Party and its
agents, employees, stockholders and directors and officers for, and holds each of them harmless against, any loss, damage, cost, claim, liability or expense (including taxes) incurred by any of them except for such actions to the extent caused by
any gross negligence or willful misconduct on the part of such Indemnified Party, arising out of or in connection with this Indenture or the Collateral Agreements or the administration of this trust, including the reasonable costs and expenses of
enforcing this Indenture against the Company or any Guarantor (including this Section 7.07) and defending themselves against any claim or liability in connection with the exercise or performance of any of their rights, powers or duties
hereunder or thereunder (including the reasonable fees and expenses of counsel). The Trustee shall notify the Company promptly of any claim asserted against an Indemnified Party for which such Indemnified Party has advised the Trustee that it may
seek indemnity hereunder or under the Collateral Agreements. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. At the Indemnified Party’s sole discretion, the Company shall defend the
claim and the Indemnified Party shall cooperate and may participate in the defense; provided that any settlement of a claim shall be approved in writing by the Indemnified Party. Alternatively, the Indemnified Party may at its option have
separate counsel of its own choosing and the Company shall pay the reasonable fees and expenses of such counsel; provided that the Company shall not be required to pay such fees and expenses if it assumes the Indemnified Party’s defense
and there is no conflict of interest between the Company and the Indemnified Party in connection with such defense as reasonably determined by the Indemnified Party. The Company need not pay for any settlement made without its written consent, which
consent shall not be unreasonably withheld. 
 To secure the Company’s and each Guarantor’s payment obligations in this
Section 7.07, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee or the Collateral Agent, in its capacity as such, for any amount owing it or any predecessor Trustee, except money
or property held in trust to pay principal of or interest on any particular Notes. 
 When an Indemnified Party incurs expenses or renders
services after an Event of Default specified in Section 6.01(6) occurs, such expenses (including the reasonable fees and expenses of its counsel) and the compensation for such services are intended to constitute expenses of
administration under any Bankruptcy Code. 
 The obligations of the Company under this Section 7.07 shall survive the
satisfaction and discharge of this Indenture, the termination of the Collateral Agreements or the resignation or removal of the Trustee. 
 The Trustee shall comply with the provisions of TIA Section 312(b)(2) to the extent applicable. 
 Section 7.08. Replacement
of Trustee. The Trustee may resign upon 45 days’ prior written notice to the Company. The Holders of a majority in aggregate principal amount of the outstanding Notes may remove the Trustee by so notifying the Company and the Trustee in
writing and may appoint a successor Trustee. The Company, by a Board Resolution, may remove the Trustee if: 
 (1) the Trustee
fails to comply with Section 7.10; 
 (2) the Trustee is adjudged bankrupt or insolvent; 
 (3) a receiver or other public officer takes charge of the Trustee or its property; or 
 (4) the Trustee becomes incapable of acting with respect to the Notes. 
  

 -71- 








 If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the
Company shall notify each Holder in writing of such event and shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the outstanding Notes may
appoint a successor Trustee to replace the successor Trustee appointed by the Company. 
 A successor Trustee shall deliver a written
acceptance of its appointment to the retiring Trustee and to the Company and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become
vested with all rights, powers, trusts, duties and obligations of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such Trustee so ceasing to act hereunder subject nevertheless
to its Lien, if any, provided for in Section 7.07. Upon request of the Company or the successor Trustee, such retiring Trustee shall at the expense of the Company and upon payment of the charges of the Trustee then unpaid, execute and
deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee, and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee
hereunder. Upon request of any such successor Trustee or the Holders of a majority in aggregate principal amount of the outstanding Notes, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to
such successor Trustee all such rights, powers and trusts. Immediately after that, the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee, subject to the Lien provided in Section 7.07, the
resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. 
 If a successor Trustee does not take office within thirty (30) days after the retiring Trustee resigns or is removed, the retiring Trustee, the
Company or the Holders of at least 10% in aggregate principal amount of the outstanding Notes may petition at the expense of the Company any court of competent jurisdiction at the expense of the Company for the appointment of a successor Trustee.

 If the Trustee fails to comply with Section 7.10, any Holder who satisfies the requirements of TIA Section 310(b)(iii)
may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 The Company
shall give notice of any resignation and any removal of the Trustee and each appointment of a successor Trustee to all Holders in writing. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office.

 Notwithstanding any resignation or replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations
under Section 7.07 shall continue for the benefit of the retiring Trustee. 
 Section 7.09. Successor Trustee by Merger,
Etc. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another Person, the resulting, surviving or transferee Person without any further act shall, if such
resulting, surviving or transferee Person is otherwise eligible hereunder, be the successor Trustee; provided, however, that such Person shall be otherwise qualified and eligible under this Article Seven. 
 In case any Notes have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes. 
  

 -72- 








 Section 7.10. Eligibility; Disqualification. 
 (a) This Indenture shall always have a Trustee who satisfies the requirements of TIA Sections 310(a)(1), (2), (3) and (5). The Trustee (or, in the
case of a Trustee that is an Affiliate of a bank holding company system, the related bank holding company) shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. In
addition, if the Trustee is a corporation included in a bank holding company system, the Trustee, independently of such bank holding company, shall meet the capital requirements of TIA Section 310(a)(2). The Trustee shall comply with TIA
Section 310(b); 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. The provisions of TIA Section 310 shall apply to the Company, as obligor of the Notes. 
 (b) If the Trustee has or acquires a conflicting interest within the meaning of the TIA, the Trustee shall either eliminate such interest or resign, to

 Section 7.13. Co-Trustees, Co-Collateral Agent and Separate Trustees, Collateral Agent. 
 (a) At any time or times, for the purpose of meeting the legal requirements of any jurisdiction in which any of the Collateral may at the time be

Trustee in the execution, delivery and performance of all instruments and agreements necessary or proper to appoint, one or more Persons approved by the Trustee either to act as co-trustee, jointly with the Trustee, of all or any part of the
Collateral, to act as co-collateral agent, jointly with the Collateral Agent, or to act as separate trustees or Collateral Agent of any such property, in either case with such powers as may be provided in the instrument of appointment, and to vest
in such Person or Persons in the capacity aforesaid, any property, title, right or power deemed necessary or desirable, subject to the other provisions of this Section 7.13. As of the Issue Date, the Company hereby appoints The Bank of
New as the initial Collateral Agent and The Bank of New York hereby accepts such appointment and agrees to act and serve in such capacity. If the Company does not join in such appointment within fifteen (15) days after the receipt by it of a
request so to do, or in case an Event of Default has occurred and is continuing, the Trustee alone shall have the power to make such appointment. 
 (b) Should any written instrument from the Company be required by any co-trustee, co-Collateral Agent or separate trustee or separate Collateral Agent so appointed for more fully confirming to such co-trustee or separate trustee such
property, title, right or power, any and all such instruments shall, on request, be executed, acknowledged and delivered by the Company.

provided in the instrument appointing such co-trustee or separate trustee or co-Collateral Agent or separate Collateral Agent, except to the extent that under any law of any jurisdiction in which any particular act is to be performed, the Trustee
shall be incompetent or unqualified to perform such act, in which event such rights, powers, duties and obligations shall be exercised and performed by such co-trustee or separate trustee, Collateral Agent or co-Collateral Agent or separate
Collateral Agent. 
 (iii) The Trustee at any time, by an instrument in writing executed by it, with the concurrence of the
Company evidenced by a Board Resolution, may accept the resignation of or remove any co-trustee or separate trustee appointed under this Section 7.13, and, in case an Event of Default has occurred and is continuing, the Trustee shall
have power to accept the resignation of, or remove, any such co-trustee, co-collateral agent, separate trustee or separate collateral agent without the concurrence of the Company. Upon the written request of the Trustee, the Company shall join with
the Trustee in the execution, delivery and performance of all instruments and agreements necessary or proper to effectuate such resignation or removal. A successor to any co-trustee, co-collateral agent, separate trustee or separate collateral agent
so resigned or removed may be appointed in the manner provided in this Section 7.13.

 ARTICLE EIGHT 
 Satisfaction and Discharge of Indenture 
 Section 8.01. Legal Defeasance and Covenant Defeasance. 
 (a) The Company may, at its option and at any time, elect to have either paragraph (b) or paragraph (c) below be applied to the outstanding Notes upon compliance with the applicable conditions
set forth in paragraph (d). 
  

 -74- 








 (b) Upon the Company’s exercise under paragraph (a) of the option applicable to this paragraph
(b), the Company and the Guarantors shall be deemed to have been released and discharged from their obligations with respect to the outstanding Notes, the Guarantees and the Collateral Agreements on the date the applicable conditions set forth below
are satisfied (hereinafter, “Legal Defeasance”). For this purpose, such Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which shall
thereafter be deemed to be “outstanding” only for the purposes of the Sections and matters under this Indenture referred to in clause (i) and (ii) below, and the Company and the Guarantors shall be deemed to have satisfied all
their other obligations under such Notes and this Indenture, the Guarantees and the Collateral Agreements, except for the following which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of outstanding
Notes to receive solely from the trust fund described in paragraph (d) below and as more fully set forth in such paragraph payments in respect of the principal of, and premium, if any, interest and Additional Interest, if any, on, such Notes
when such payments are due, (ii) obligations listed in Section 8.03, subject to compliance with this Section 8.01 and (iii) the rights, powers, trust, duties and immunities of the Trustee and the Company’s
obligations in connection therewith. The Company may exercise its option under this paragraph (b) notwithstanding the prior exercise of its option under paragraph (c) below with respect to the Notes. 
 (c) Upon the Company’s exercise under paragraph (a) of the option applicable to this paragraph (c), the Company and its Restricted
Subsidiaries shall be released and discharged from their obligations under any covenant contained in Sections 4.05, 4.08, and 4.10 through 4.33 (provided that the release and discharge of the Company’s
obligations under Section 4.26 shall in no way relieve the Company of its obligation to pay any Additional Interest when due and payable) and clause (2) of the first paragraph of Section 5.01 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 to be not “outstanding” for the purpose of any direction,
waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes
shall not be deemed outstanding for accounting purposes). For this purpose, such Covenant Defeasance means that, with respect to the outstanding Notes and the Guarantees, the Company 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 6.01, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In
addition, upon the Company’s exercise under paragraph (a) hereof of the option applicable to this paragraph (c), subject to the satisfaction of the conditions set forth in paragraph (d) below, Section 6.01(3) (solely as
such Section 6.01(3) pertains to Sections 4.05, 4.08, and 4.10 through 4.26 (provided that the release and discharge of the Company’s obligations under Section 4.26 shall in no
way relieve the Company of its obligation to pay any Additional Interest when due and payable) and clause (2) of the first paragraph of Section 5.01), 6.01(4), 6.01(5), 6.01(8), 6.01(9) and
6.01(10) shall not constitute Events of Default. 
 (d) The following shall be the conditions to application of either paragraph
(b) or paragraph (c) above to the outstanding Notes: 
 (1) the Company shall have irrevocably deposited with the
Trustee, in trust, for the benefit of the Holders, U.S. Legal Tender or non-callable U.S. Government Obligations or a combination thereof, in such amounts and at such times as are sufficient, in the opinion of a nationally-recognized firm of
independent public accountants, to pay the principal of, and premium, if any, interest and Additional Interest, if any, on, the outstanding Notes on the stated dates for payment or redemption, as the case may be; 
  

 -75- 








 (2) in the case of Legal Defeasance, the Company shall have delivered to the Trustee an
Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that: 
 (a) the Company has received
from, or there has been published by, the Internal Revenue Service a ruling; or 
 (b) since the date of this Indenture, there
has been a change in the applicable federal income tax law, 
 in either case to the effect that, and based thereon such Opinion of Counsel
shall confirm that, the Holders 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; 
 (3) in the case of Covenant Defeasance, the Company
shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders 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; 
 (4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit pursuant to clause (1) of this
paragraph (except such Default or Event of Default resulting from the failure to comply with Section 4.12 or Section 4.16 as a result of the borrowing of funds required to effect such deposit) or insofar as Defaults or Events
of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of such deposit; 
 (5) such Legal Defeasance or Covenant Defeasance shall not result in a breach of, or constitute a default under any other material agreement or instrument to which the Company or any of its Subsidiaries is a party or
by which the Company or any of its Subsidiaries is bound; 
 (6) the Company shall have delivered to the Trustee an
Officers’ Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders over any other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding any other creditors
of the Company or others; 
 (7) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion
of Counsel, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with; and 
 (8) The Company shall have delivered to the Trustee an Opinion of Counsel (subject to customary qualifications and exclusions) to the
effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940. 
 Notwithstanding the foregoing, the Opinion of Counsel required by Section 8.01(d)(2) above with respect to a Legal Defeasance need not be delivered if all Notes not theretofore delivered to the Trustee for cancellation
(1) have become due and payable or (2) shall become due and payable on the maturity date within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense,
of the Company. 
  

 -76- 








 In the event all or any portion of the Notes are to be redeemed through such irrevocable trust, the
Company must make arrangements reasonably satisfactory to the Trustee, at the time of such deposit, for the giving of the notice of such redemption or redemptions by the Trustee in the name and at the expense of the Company. 
 Section 8.02. Satisfaction and Discharge. In addition to the Company’s rights under Section 8.01, this Indenture (subject to
Section 8.03) and all Liens on Collateral will be discharged and will cease to be of further effect as to all outstanding Notes, when: 
 (1) either:

 Section 8.05. Application of Trust Moneys. The Trustee shall hold any U.S. Legal Tender or U.S.
Government Obligations deposited with it in the irrevocable trust established pursuant to Section 8.01. The Trustee shall apply the deposited U.S. Legal Tender or the U.S. Government Obligations, together with earnings thereon, through
the Paying Agent, in accordance with this Indenture and the terms of the irrevocable trust agreement established pursuant to Section 8.01, to the payment of principal of, premium, if any, and interest (including Additional Interest, if
any) on the Notes. Anything in this Article Eight to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the Company’s request any U.S. Legal Tender or U.S. Government Obligations held by
it as provided in Section 8.01(d) 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 that

prohibiting such application, the Company’s and each Guarantor’s obligations under this Indenture, the Collateral Agreements, the Guarantees and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to
Section 8.01 or 8.02 until such time as the Trustee or Paying Agent is permitted to apply all such U.S. Legal Tender or U.S. Government Obligations in accordance with Section 8.01 or 8.02; provided,
however, that if the Company has made any payment of premium, if any, or interest on or principal of any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to

 It shall not be necessary for the consent of
the Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 
 After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall mail to the Holders affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture. 
  

 -80- 








 Section 9.03. Compliance with TIA. Every amendment, waiver or supplement of this Indenture, the
Notes, the Collateral Agreements or the Guarantees shall comply with the TIA as then in effect. 
 Section 9.04. Revocation and Effect of
Consents. Until an amendment, waiver or supplement becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting
Holder’s Note, even if notation of the consent is not made on any Note. Subject to the following paragraph, any such Holder or subsequent Holder may revoke the consent as to such Holder’s Note or portion of such Note by written notice to
the Trustee and the Company received before the date on which the Trustee, and if such amendment, waiver or supplement relates to any Collateral Agreement, the Collateral Agent, receives an Officers’ Certificate certifying that the Holders of
the requisite principal amount of Notes have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver. 
 The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver, which record date shall be either (i) at least thirty
(30) days prior to the first solicitation of such consent or (ii) the date of the most recent list furnished to the Trustee under Section 2.05. If a record date is fixed, then notwithstanding the last sentence of the
immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to revoke any consent previously given, whether or not such Persons continue to be
Holders after such record date. No such consent shall be valid or effective for more than ninety (90) days after such record date. 
 After an amendment, supplement or waiver becomes effective, it shall bind every Holder unless it makes a change described in any clauses of Section 9.02, in which case, the amendment, supplement or waiver shall bind only each
Holder of a Note who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note; provided that any such waiver shall not impair or affect the right of any
Holder to receive payment of principal of, premium, if any, and interest on a Note, on or after the respective due dates expressed in such Note, or to bring suit for the enforcement of any such payment on or after such respective dates without the
consent of such Holder. 
 Section 9.05. Notation on or Exchange of Notes. If an amendment, supplement or waiver changes the terms of
a Note, the Trustee may require the Holder of the Note to deliver the Note to the Trustee. The Trustee at the written direction of the Company may place an appropriate notation on the Note about the changed terms and return it to the Holder and the
Trustee may place an appropriate notation on any Note thereafter authenticated. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects
the changed terms. Failure to make an appropriate notation, or issue a new Note, shall not affect the validity and effect of such amendment, supplement or waiver. Any such notation or exchange shall be made at the sole cost and expense of the
Company. Failure to make the appropriate notation or issue a new Note shall not effect the validity and effect of such amendment, supplement or waiver. 
 Section 9.06. Trustee to Sign Amendments, Etc. The Trustee and/or the Collateral Agent, as applicable, shall execute any amendment, supplement or waiver authorized pursuant to this Article Nine;
provided that the Trustee or the Collateral Agent, as the case may be, may, but shall not be obligated to, execute any such amendment, supplement or waiver which adversely affects the rights, duties or immunities of the Trustee or the
Collateral Agent, as the case may be, under this Indenture or any Collateral Agreement. The Trustee or the Collateral Agent, as the case may be, shall be provided 

  

 -81- 








 
with, and shall be fully protected in relying upon, an Opinion of Counsel and an Officers’ Certificate each stating that the execution of any amendment,
supplement or waiver authorized pursuant to this Article Nine is authorized or permitted by this Indenture. Such Opinion of Counsel shall also state that the amendment or supplement is a valid and enforceable obligation of the Company. Such
Opinion of Counsel shall not be an expense of the Trustee or the Collateral Agent, as the case may be, and shall be paid for by the Company. 
 Section 9.07. Conformity with Trust Indenture Act. Every supplemental indenture executed pursuant to this Article Nine shall conform to the requirements of the TIA as then in effect. 
 ARTICLE TEN 
 Guarantee

 Section 10.01. Guarantee. Each Guarantor hereby fully, irrevocably and unconditionally, jointly and severally, unconditionally
and irrevocably guarantees (such guarantee to be referred to herein as the “Guarantee”), to each of the Holders and to the Trustee and the Collateral Agent and their respective successors and assigns that (i) the principal of,
premium, if any and interest on the Notes shall be promptly paid in full when due, subject to any applicable grace period, whether upon redemption pursuant to the terms of the Notes, by acceleration or otherwise, and interest on the overdue
principal (including interest accruing at the then applicable rate provided in this Indenture, the Notes, the Guarantees and the Collateral Agreements after the occurrence of any Event of Default set forth in Sections 6.01(6) or (7),
whether or not a claim for post-filing or post-petition interest is allowed under applicable law following the institution of a proceeding under bankruptcy, insolvency or similar laws), if any, and interest on any interest, if any, to the extent
lawful, of the Notes and all other obligations of the Company to the Holders, the Trustee and the Collateral Agent hereunder, thereunder or under any Collateral Agreement shall be promptly paid in full or performed, all in accordance with the terms
hereof, thereof and of the Collateral Agreements ; and (ii) in case of any extension of time of payment or renewal of any of the Notes or of any such other obligations, the same shall be promptly paid in full when due or performed in accordance
with the terms of the extension or renewal, subject to any applicable grace period, whether at stated maturity, by acceleration or otherwise, subject, however, in the case of clauses (i) and (ii) above, to the limitations set forth in
Section 10.03. The Guarantee of each Guarantor shall rank senior in right of payment to all existing and future subordinated Indebtedness of such Guarantor and equal in right of payment with all other existing and future senior
obligations of such Guarantor, including borrowings or guarantees of borrowings under the Credit Agreement. Each Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or
enforceability of the Notes, this Indenture or any Collateral Agreement, the absence of any action to enforce the same, any waiver or consent by any of the Holders with respect to any provisions hereof or thereof, any release of any other Guarantor,
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 Guarantor hereby waives diligence,
presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that this
Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes, this Indenture and in this Guarantee. Each Guarantor may consolidate with or merge into or sell its assets to the Company or another
Guarantor without limitation in accordance with Sections 5.01 and 4.16. If any Holder or the Trustee is required by any court or otherwise to return to the Company, any Guarantor, or any custodian, trustee, liquidator or other similar
official acting in relation to the Company or any Guarantor, any amount paid by the Company or any Guarantor to the Trustee, the Collateral Agent or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force
and effect. Each Guarantor further agrees that, as between each Guarantor, on the one hand, 

  

 -82- 








 
and the Holders, the Collateral Agent and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as
provided in Article Six for the purposes of this 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 Six, such obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the purpose of this Guarantee. 
 Section 10.02. Release of a Guarantor. A Guarantor will be released from its Guarantee and the Collateral Agreements (and may subsequently
dissolve) without any action required on the part of the Trustee or any Holder: 
 (1) if (a) all of the Capital Stock
issued by such Guarantor or all or substantially all of the assets of such Guarantor are sold or otherwise disposed of (including by way of merger or consolidation) to a Person other than the Company or any of its Domestic Restricted Subsidiaries or
(b) such Guarantor ceases to be a Restricted Subsidiary, and the Company otherwise complies, to the extent applicable, with Section 4.16, or 
 (2) if the Company designates such Guarantor as an Unrestricted Subsidiary in accordance with the definition thereof, or 
 (3) if the Company exercises its Legal Defeasance option or its Covenant Defeasance option as described in Section 8.01, or

 (4) upon satisfaction and discharge of this Indenture or payment in full of the principal of, and premium, if any, and
accrued and unpaid interest and Additional Interest, if any, on, the Notes and all other Obligations that are then due and payable. 
 The
Trustee shall promptly deliver an appropriate instrument evidencing such release upon receipt of a request by the Company accompanied by an Officers’ Certificate certifying as to the compliance with this Section 10.02. At the
Company’s request and expense, the Trustee will execute and deliver an instrument evidencing such release. Any Guarantor not so released remains liable for the full amount of its Guarantee as provided in this Article Ten. 
 Section 10.03. Limitation of Guarantor’s Liability. Each Guarantor and, by its acceptance hereof, each of the Holders hereby confirms that it
is the intention of all such parties that the guarantee by such Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of any 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 such Guarantor hereby irrevocably agree that the obligations of such Guarantor under the Guarantee shall be limited to the maximum amount as
shall, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor
under its Guarantee or pursuant to Section 10.05, result in the obligations of such Guarantor under the Guarantee not constituting such fraudulent transfer or conveyance. The net worth of any Guarantor for such purpose shall include any
claim of such Guarantor against the Company for reimbursement and any claim against any other Guarantor for contribution. 
 Section 10.04.
Guarantors May Consolidate, etc., on Certain Terms. Each Guarantor (other than any Guarantor whose Guarantee is to be released in accordance with the terms of the Guarantee and this Indenture in connection with any transaction complying with
Section 4.16) will not, and the Company will not cause or permit any Guarantor to, consolidate with or merge with or into any Person other than the Company or any other Guarantor unless: 
 (1) the entity formed by or surviving any such consolidation or merger (if other than the Guarantor) or to which such sale, lease,
conveyance or other disposition shall have been made is a corporation organized and existing under the laws of the United States or any State thereof or the District of Columbia; 
  

 -83- 








 (2) such entity assumes by (i) supplemental indenture (in form and substance
reasonably satisfactory to the Trustee), executed and delivered to the Trustee, all of the obligations of the Guarantor under the Guarantee and the performance of every covenant of the Guarantee and this Indenture (ii) amendment, supplement or
other instrument (in form and substance satisfactory to the Trustee and the Collateral Agent) executed and delivered to the Trustee and the Collateral Agent, all obligations of the Guarantor under the Collateral Agreements and in connection
therewith shall cause such instruments to be filed and recorded in such jurisdictions and take such other actions as may be required by applicable law to perfect or continue the perfection of the Lien created under the Collateral Agreements on the
Collateral owned by or transferred to the surviving entity; and 
 (3) immediately after giving effect to such transaction, no
Default or Event of Default shall have occurred and be continuing. 
 Notwithstanding the foregoing, any merger or consolidation of
(i) a Guarantor with and into the Company (with the Company being the surviving entity) or another Guarantor or (ii) a Guarantor or the Company with an Affiliate organized solely for the purpose of reincorporating such Guarantor or the
Company in another jurisdiction in the United States or any state thereof or the District of Columbia need only comply with (A) clause (4) the first paragraph of Section 5.01 and (B)(x) in the case of a merger or consolidation
involving the Company as described in clause (ii) above, clause (1)(b)(y) of the first paragraph of Section 5.01 and (y) in the case of a merger or consolidation involving the Guarantor as described in clause (ii), clause
(2) of the first paragraph of this Section 10.04. 
 Section 10.05. Contribution. In order to provide for just and
equitable contribution among the Guarantors, the Guarantors agree, inter se, that each Guarantor that makes a payment or distribution under a Guarantee shall be entitled to a pro rata contribution from each other Guarantor hereunder
based on the net assets of each other Guarantor. The preceding sentence shall in no way affect the rights of the Holders of Notes to the benefits of this Indenture, the Notes or the Guarantees. 
 Section 10.06. Waiver of Subrogation. Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders
in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. 
 Section 10.07. Evidence of
Guarantee. To evidence their guarantees to the Holders set forth in this Article Ten, each of the Guarantors hereby agrees to execute the notation of Guarantee in substantially the form included in the Notes attached as Exhibits A and B.
Each such notation of Guarantee shall be signed on behalf of each Guarantor by an Officer or an assistant Secretary. An Officer (who shall, in each case, have been duly authorized by all requisite corporate actions) of the Guarantors shall execute
the Guarantees by manual or facsimile signature. 
 If an Officer whose signature is on a Note was an Officer at the time of such execution
but no longer holds that office or position at the time the Trustee authenticates such Note, such Note shall nevertheless be valid. 
  

 -84- 








 Each Guarantor hereby agrees that its Guarantee set forth in Section 10.01 shall remain in
full force and effect notwithstanding any failure to endorse on each Note a notation of such Guarantee. 
 If an Officer or assistant
Secretary whose signature is on this Indenture or on the Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Guarantee is endorsed, the Guarantee shall be valid nevertheless. 
 The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee set forth in this
Indenture on behalf of the Guarantors. 
 Section 10.08. Waiver of Stay, Extension or Usury Laws. Each Guarantor covenants to the
extent permitted by law that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive such Guarantor
from performing its Guarantee as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Guarantee; and each Guarantor hereby expressly waives to the extent permitted
by law all benefit or advantage of any such law, and covenants that it shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law
had been enacted.
