 WHEREAS, all things necessary to make the Notes and Guarantees, when each are duly issued and executed by the Company and the Guarantors, as applicable,

have been done. 
 NOW, THEREFORE, each party hereto agrees as follows for the benefit of the other parties and for the equal and ratable
benefit of the Holders: 
 ARTICLE ONE 
 Definitions and Incorporation by Reference 
 Section 1.01. Definitions 
 “Acquired Indebtedness” means Indebtedness of a Person or any of its Subsidiaries (a) existing at the time such Person becomes a
Restricted Subsidiary of the Company or at the time it merges or consolidates with or into the Company or any of its Restricted Subsidiaries or (b) assumed in connection with the acquisition of assets from such Person and in each case not
incurred by such Person in connection with, or in anticipation or contemplation of, such Person becoming a Restricted Subsidiary of the Company or such acquisition, merger or consolidation and which Indebtedness is without recourse to the Company or
any of its Subsidiaries or to any of their respective properties or assets other than the Person or the assets to which such Indebtedness related prior to the time such Person became a Restricted Subsidiary of the Company or the time of such
acquisition, merger or consolidation. 
 “Acquisition” means: 
 (1) an Investment by the Company or any Subsidiary of the Company in any other Person (other than a Restricted Subsidiary of the Company)
pursuant to which the Company or such Subsidiary acquires, whether directly or indirectly, the Capital Stock of such other Person or the right to acquire any such Capital Stock (including an Investment in the Indebtedness of such other Person that
is convertible in to the Capital Stock of such other Person); or 
 (2) the acquisition by the Company or any Restricted
Subsidiary of the Company of the assets of any Person (other than a Restricted Subsidiary of the Company) which constitute all or substantially all of the assets of such Person or comprise any division or line of business of such Person or other

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

 (2) the acquisition by the Company or any Restricted Subsidiary of the Company of the assets of any Person (other than a Restricted
Subsidiary of the Company) which constitute all or substantially all of the assets of such Person or comprise any division or line of business of such Person or any other properties or assets of such Person other than in the ordinary course of
business. 
 “Asset Sale” means any direct or indirect sale, issuance, conveyance, transfer, lease (other than operating

Guarantor of: 
 (1) any Capital Stock of any Restricted Subsidiary of the Company; or 
  

 -2- 

 (2) any other property or assets of the Company or any Restricted Subsidiary of the
Company other than in the ordinary course of business; provided, however, that Asset Sales shall not include:

 (e) the sale or other disposal of the Collateral pursuant to the exercise of any remedies pursuant to the documents relating to any First
Priority Claims that are permitted under this Indenture and secured by Permitted Liens of the type described in clause (11), (15) or (18) of the definition thereof; 
 (f) the sale or other disposition of used, worn out, obsolete or surplus equipment; and

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

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 2.15 and 2.16, 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, 5.15, 5.16 or 10.05, in which event the Company shall be responsible for the payment of such taxes).

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.

be effected only through the Depository, in accordance with this Indenture and the Applicable Procedures. 
 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, 

  

 -33- 

 
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. 
 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, Conversion Agent and the Paying Agent shall forward to the Trustee any Notes surrendered to them for transfer, exchange,
payment or conversion. 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 

  

 -34- 

 
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. Issuance of PIK Notes. For any Interest Payment Date after the initial Interest Payment Date, the Company may, at its
option, elect to pay interest on the Notes (1) entirely in cash (“Cash Interest”) or (2) entirely by increasing the principal amount of the outstanding notes or by issuing additional PIK Notes in an aggregate principal
amount equal to the amount of interest (rounded to the nearest whole cent) that would be payable with respect to the Notes if such interest were paid in cash provided, on any Record Date, should the sum of clauses (iii) A-F of the first
paragraph of Section 5.10 be equal to or greater than 50% of the accrued and unpaid interest due on an Interest Payment Date, the Company shall be required to pay 50% of the interest then due on such Interest Payment Date in cash to the
Holders (“PIK Interest”). Any PIK Notes so issued shall be dated the applicable Interest Date, shall bear interest from and after such date, and shall mature on October 1, 2013. The Company may not issue PIK Notes in lieu of
paying interest in cash if such interest is default interest or such interest is due and payable with respect to any principal that is due and payable, whether at maturity, upon redemption or otherwise. 
 With respect to any PIK Notes, the Company shall deliver to the Trustee: 
 (1) no later than five Business Days prior to the beginning of each such Interest Payment Date, a written notice setting forth the extent
to which such interest payment will be made in the form of PIK Interest, and within five Business Days of the receipt thereof, the Trustee shall deliver a corresponding notice to the Holders; and 
 (2) no later than one Business day prior to the relevant Interest Payment Date, an order to authenticate and deliver such PIK Notes.

 Any PIK Notes shall, after being executed and authenticated pursuant to Section 2.01, be (i) delivered by the Trustee to
such Holders as of the relevant Record Date at such Holders’ registered address that hold Notes in the form of physical Notes, or (ii) deposited with or on behalf of DTC for the benefit of the beneficial owners of the Notes as of the
relevant record date with respect to the notes that are held in global form. 
 In the absence of such an election for any Interest Payment
Date, interest on the Notes shall be payable according to the election for previous Interest Payment Date. Interest for the first Interest Payment Date commencing on the date of this Indenture shall be payable entirely in cash. Notwithstanding
anything to the contrary, the payment of accrued interest in connection with any redemption or repurchase of Notes as described under Section 3.01, Section 5.15 and Section 5.16 shall be made solely in cash. 
  

 -35- 

 Section 2.14. 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 2.15. 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 B. 
 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 2.16, 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. 
 (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. 
  

 -36- 

 (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 2.16, 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 2.16. 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, 
 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 

  

 -37- 

 
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 2.16 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. 
 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 2.15 or this Section 2.16. 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.

 ARTICLE THREE 
 Redemption 
 Section 3.01. Optional Redemption. Semi-annually beginning on October 1,
2009, we may redeem up to 25% of the principal amount of the Notes then outstanding at a Redemption Price of 100% of the aggregate principal amount thereof, plus accrued and unpaid interest thereon, to the Redemption Date, only in the event the
closing price of shares of the Company’s Common Stock equals 150% or more of the Conversion Price then in effect for 20 of any 30 consecutive trading days, provided should we redeem any Notes prior to October 1, 2010 the Holders shall be
entitled to the make-whole premium set forth below under Section 4.10 as if the Redemption Date were the Conversion Date. 
 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. 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
Conversion Price; 
 (4) the name and address of the Paying Agent and the Conversion Agent; 
 (5) the CUSIP number; 
  

 -39- 

 (6) the subparagraph of the Notes pursuant to which such redemption is being made;

 (7) 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; 
 (8) 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; 
 (9) 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 
 (10) 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 Eight. 
 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. 
 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 
 Conversion 
 Section 4.01. Conversion Right and Conversion Rate. 
 (a) Subject to and upon compliance with the provisions of this Article Four, at the option of the Holder thereof, any portion of the principal
amount of any Note that is an integral multiple of $1,000 may be converted into fully paid and non-assessable shares of Common Stock at the Conversion Rate, determined as hereinafter provided, in effect at the time of conversion. The Holders may
surrender Notes for conversion at the applicable Conversion Rate at any time after the Original Issue Date until the close of business on the Business Day immediately preceding the final maturity date of the Notes. 
 (b) All calculations under this Article Four shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be.

 Section 4.02. Conversion Consideration. 
 (a) Upon surrendering any Notes for conversion, the Holder of such Notes shall receive, in respect of each $1,000 principal amount of Notes, shares of Common Stock at an initial conversion rate of 1,389.00 shares per
$1,000 principal amount of Notes (the “Conversion Rate”), which is based upon an initial Conversion Price of $0.72 per share. The Conversion Rate (and Conversion Price) are subject to adjustment as provided in
Section 4.05. 
 (b) The Holders at the close of business on a Record Date will be entitled to receive the interest payment on
those Notes on the corresponding Interest Payment Date notwithstanding the conversion of such Notes following that Record Date or the Company’s default in payment of the interest due on that Interest Payment Date. However, Notes surrendered for
conversion during the period between the close of business on any Record Date and the close of business on the Business Day immediately preceding the applicable Interest Payment Date must be accompanied by payment of an amount equal to the interest
payable on such Notes on that Interest Payment Date. A Holder on a Record Date who (or whose transferee) tenders any Notes for conversion on the corresponding Interest Payment Date will receive the interest payable on Notes on that date, and the
converting Holder need not include payment in the amount of such interest upon surrender of Notes for conversion. Notwithstanding the foregoing, if Notes are converted during the period between the close of business on any Record Date and the
opening of business on the corresponding Interest Payment Date and the Company has specified a Change of Control Payment Date (as defined below) during such period or on such corresponding Interest Payment Date pursuant to the Change of Control
redemption provisions described in Section 5.15, the Holder who tenders such Notes for conversion shall receive the interest payable on such Interest Payment Date and need not include payment of the amount of such interest upon surrender
of its Notes for conversion. 
 Except as provided above with respect to a voluntary conversion, the Company shall make no payment or
allowance for unpaid interest, whether or not in arrears, on converted Notes or for dividends on the shares of Common Stock issued upon conversion. 
  

 -41- 

 Section 4.03. Exercise of Conversion Right. 
 (a) In order to exercise the conversion right: 
 (i) the Holder of any Physical Note to be converted must (1) complete and manually sign a notice of conversion substantially in the form set forth on the reverse of the Note (the “Conversion
Notice”); (2) deliver the Conversion Notice and the Physical Note (and the Certificate of Conversion & Restricted Transfer (defined below), if applicable) to the Conversion Agent and the Company; and (3) if required,
furnish appropriate endorsements and transfer documents; or 
 (ii) the holder of beneficial interests in any Global Note to
be converted must comply with the Applicable Procedures to cause the beneficial interests in such Global Note to be delivered to the Conversion Agent, 
 and, in either case, the Holder of a Physical Note or Holder of beneficial interests in a Global Note will, if required, pay all transfer or similar taxes and, if required pursuant to Section 4.03(b) hereof, pay funds equal to
the interest payable on the next interest payment date. 
 The date on which a Holder of a Physical Note or Holder of a beneficial interest
in a Global Note completes the requirements of this Section 4.03(a) shall be deemed to be the date of conversion (the “Conversion Date”) for purposes of this Article 4. On and after the Conversion Date, the
conversion by such Holder, as set forth in the Conversion Notice, shall become irrevocable. 
 (b) Notes shall be deemed to have been
converted immediately prior to the close of business on the Conversion Date, and at such time the rights of the Holders of such Notes as Holders will cease, and the Person or Persons entitled to receive the shares of Common Stock payable and
issuable upon conversion will be treated for all purposes as the payee or payees of such payment and the record holder or holders of such Common Stock at such time. Following any Conversion Date, the Company shall satisfy its obligations with
respect to such conversion by either: 
 (i) delivering to the Trustee, for delivery to the Holder (or such other Person as
may be named in the relevant Conversion Notice), the cash payment, together with certificates representing the number of shares of Common Stock, payable and issuable upon the conversion; or 
 (ii) delivering to such Holder (or such other Person as may be named in the relevant Conversion Notice) the cash payment, together with
such number of shares of Common Stock payable and issuable upon such conversion in accordance with the Applicable Procedures, 
 in each case, together with
payment in lieu of fractional shares, if any, as provided in Section 4.04 (such cash payment and delivery of shares, if any, the “Settlement”); provided that shares of Common Stock only will be deliverable in
certificated form if (1) the Holder or holder that is exercising such conversion has specifically requested in writing that delivery be in certificates or (2) the Company determines that delivery is required in certificated shares either
because (A) delivery to the Holder (or such other Person named in the relevant Conversion Notice) is not practicable in accordance with the Applicable Procedures or (B) in the opinion of legal counsel, delivery is required in certificated
form in order to comply with the requirements of applicable securities laws. Settlement shall occur promptly. 
 (c) In the case of any Note
which is converted in part only, upon such conversion the Company shall execute and the Trustee shall authenticate and deliver to the Holder thereof, at the expense of the Company, a new Note or Notes of authorized denominations in an aggregate
principal amount equal to the unconverted portion of the principal amount of such Note. A Note may be converted in part but only if the principal amount of such Note to be converted is any integral multiple of $1,000 and the principal amount of such
security to remain outstanding after such conversion is equal to $1,000 or any integral multiple of $1,000 in excess thereof. 
  

 -42- 

 (d) If shares of Common Stock to be issued upon conversion of a Note constituting a Restricted Security,
or Notes to be issued upon conversion of a Note constituting a Restricted Security in part only, are to be registered in a name other than that of the Beneficial Owner of such Restricted Security, then such Holder must deliver to the Conversion
Agent a certificate of conversion and restricted transfer in the form of Exhibit C hereto (the “Certificate of Conversion & Restricted Transfer”), dated the date of surrender of such Note constituting a Restricted
Security and signed by such Beneficial Owner, as to compliance with the restrictions on transfer applicable to such Restricted Security. The Certificate of Conversion & Restricted Transfer shall be required in addition to the Conversion
Notice. None of the Trustee, any Conversion Agent, Registrar or transfer agent shall be required to register shares of Common Stock issued upon conversion or any unconverted Notes in the name of any Person other than that of the Holder or Beneficial
Owner of the converted Restricted Security unless such Holder or Beneficial Owner has delivered a properly completed Certificate of Conversion & Restricted Transfer. 
 All shares of Common Stock delivered upon conversion of Notes constituting Restricted Securities shall bear restrictive legends substantially in the form
of the legends required to be set forth on the Restricted Securities pursuant to Section 2.16 hereof and shall be subject to the restrictions on transfer provided in such legends. Neither the Trustee nor any Conversion Agent shall have
any responsibility for the inclusion or content of any such restrictive legends on such Common Stock. 
 Section 4.04. Fractions of
Shares. No fractional shares of Common Stock shall be issued upon conversion of any Note or Notes. If more than one Note shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issuable upon
conversion thereof shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof) so surrendered. Instead of any fractional share of Common Stock that would otherwise be issuable upon conversion of any
Note or Notes (or specified portions thereof), the Company shall calculate and pay a cash adjustment for the fractional amount (calculated to the nearest 1/100th of a share) based upon the applicable Conversion Price. The amount of the cash
adjustment payable in lieu of issuing such fractional share shall be equal to such fractional share otherwise issuable multiplied by the Closing Sale Price on the applicable Trading Day. 
 Section 4.05. Adjustment of Conversion Rate. 
 (a) Adjustment. The Conversion Rate or the Conversion Price will be subject to adjustment, without duplication, from time to time upon the occurrence of any of the following events: 
 (i) Stock Dividends in Common Stock. In case the Company shall pay or make a dividend or other distribution on shares of Common
Stock payable exclusively in shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be
increased by dividing such Conversion Rate by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination and the denominator shall be the sum of such
number of shares and the total number of shares constituting such dividend or other distribution, such increase to become effective immediately after the opening of business on the day following the date fixed for such determination. If, after any
such date fixed for determination, any dividend or distribution is not in fact paid, the Conversion Rate shall be immediately readjusted, effective as of the date the Company’s Board of Directors determines not to pay such dividend or
distribution, 

  

 -43- 

 
to the Conversion Rate that would have been in effect if such determination date had not been fixed. For the purposes of this clause (i), the number of
shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will
not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. 
 (ii)
Certain Offerings. In the event the Company issues or sells any Common Stock or any securities convertible into or exchangeable or exercisable for shares of Common Stock (other than Consideration Shares and as otherwise excluded pursuant to
Section 4.05(b)(ii)) in one or more transactions at a weighted average effective price per share of less than $0.63 per share of Common Stock (after taking into account the price per share at which all convertible, exchangeable or
exercisable securities could be converted, exchanged or exercised for), the Conversion Price will be adjusted according to the following formula: 
 CP’ = CP0 x ((S0 x P0) + (Si x Pi)) / Sn / P0 
 Where: 
 CP’ = Conversion Price in
effect after such issuance 
 CP0
 = Conversion Price in effect immediately before such issuance 
 S0 = Number of shares of Common Stock outstanding as of the Issue Date 
 P0 =
$ 
 Si = Number of shares of Common Stock issued for which the Conversion Price will be adjusted 
 Pi =
Price at which shares of Common Stock are issued for which the Conversion Price will be adjusted 
 Sn = Number of shares of Common Stock outstanding immediately following such transaction 
 Notwithstanding the foregoing, in no event will the Conversion Price be adjusted to less than $0.44 pursuant to this clause (ii), subject to adjustment in accordance
with clauses (i), (iii) and (iv) of this Section 4.05(a). 
 (iii) Stock Subdivisions, Combinations
and Reclassifications. 
 (1) In case outstanding shares of Common Stock shall be subdivided or split into a greater
number of shares of Common Stock, then the Conversion Rate in effect at the opening of business on the day following the day upon which such subdivision or split becomes effective shall be proportionately increased, 
 (2) in case outstanding shares of Common Stock shall be combined or reclassified into a smaller number of shares of Common Stock, then the
Conversion Rate in effect at the opening of business on the day following the day upon which such combination or reclassification becomes effective shall be proportionately reduced, and 
  

 -44- 

 (3) in case the Company issues any shares of its Capital Stock in a reclassification of
the outstanding shares of Common Stock, then the Conversion Rate in effect at the opening of business on the day following the day upon which such reclassification becomes effective shall be proportionately applied to the new class of shares of
Capital Stock of the Company into which the Common Stock was reclassified, in each case, such increase, reduction or reclassification, as the case may be, to become effective immediately after the opening of business on the Business Day following
the day upon which such subdivision, combination or reclassification becomes effective. 
 (iv) Shareholder Rights
Plan. To the extent that the Company has a shareholder rights plan in effect upon the conversion of the Notes into Common Stock, a Holder will receive, in addition to the Common Stock, the rights under the shareholder rights plan unless the
rights have separated from the Common Stock prior to the time of conversion, in which case the Conversion Rate will be adjusted at the time of separation as if the Company had made a distribution referred to in clause (vi) below, subject to
readjustment in the event of the expiration, termination or redemption of such rights. 
 (v) Cash Distributions. In
case the Company shall, by dividend or otherwise, distribute to all or substantially all holders of outstanding shares of Common Stock distributions consisting exclusively of cash (excluding any dividend or distribution in connection with the
Company’s liquidation, dissolution or winding up) then the Conversion Price will be adjusted by multiplying: 
 (1) the
Conversion Price 
 by 
 (2) a fraction, the numerator of which shall be the Market Value of a share of Common Stock minus the amount per share of such dividend, and the denominator of which shall be the Market Value of a share of Common
Stock. 
 Notwithstanding the foregoing, in no event will the Conversion Price be adjusted to less than $0.44 pursuant to this clause (v), subject to
adjustment in accordance with clauses (i), (iii) and (iv) of this Section 4.05(a). 
 (vi)
Distribution of Indebtedness, Securities or Assets. In case the Company shall, by dividend or otherwise, distribute to all or substantially all holders of Common Stock evidences of its indebtedness, shares of Capital Stock other than Common
Stock, or assets (including securities, but excluding (1) any dividends or distributions referred to in clause (i) of this Section 4.05(a), (2) any rights, warrants or options referred to in clause (iii) of this
Section 4.05(a) and (3) any dividends or distributions paid exclusively in cash described in clause (viii) of this Section 4.05(a) (the “Distributed Assets”), then the Conversion Price shall be
adjusted by multiplying: 
 (1) the Conversion Price 
 by 
 (2) a
fraction, the numerator of which will be the Market Value of a share of Common Stock minus the Fair Market Value (as determined in good faith by the Board of Directors, whose determination shall be conclusive) of the portion of the Distributed
Assets so distributed applicable to one share of Common Stock, and the denominator of which shall be the Market Value of one share of Common Stock. 
  

 -45- 

 If after any such date fixed for determination, any such distribution is not in fact
made, the Conversion Price shall be immediately readjusted, effective as of the date the Company’s Board of Directors determines not to make such distribution, to the Conversion Rate that would have been in effect if such determination date had
not been fixed. 
 Notwithstanding the foregoing, in no event will the Conversion Price be adjusted to less than $0.44
pursuant to this clause (vi), subject to adjustment in accordance with clauses (i), (iii) and (iv) of this Section 4.05(a). 
 (vii) Reset Provision. If the volume weighted average price of the Common Stock for the 30 trading days up to and including December 31, 2008 is less than $0.63 (the “Reset Threshold”)
then, effective as of January 1, 2009, the Conversion Price will decrease to the higher of (A) $0.44 (the “Indicated Price”) or (B) the volume weighted average price of the Common Stock for the 30 trading days up to
and including December 31, 2008 plus 5.0%, provided that in the event that the Conversion Price is decreased to the Indicated Price, the interest rate on the Notes shall increase by 3.00%, all set forth above is subject to adjustment as
set forth under Section 4.05(a). In the event that the volume weighted average price of the Common Stock for the 30 trading days up to and including December 31, 2008 is less than the Reset Threshold, the Company shall notify the
Holders of such fact within 30 days of January 1, 2009 and shall include in such notice the adjusted interest rate and Conversion Price. 
 (b) No Adjustment. 
 (i) No adjustment of the Conversion Price shall be required unless such adjustment would
require an increase or decrease of at least 1.0% of the Conversion Price then in effect. Any lesser adjustment shall be carried forward and shall be made at the time of and together with the next subsequent adjustment, if any, which, together with
any adjustment or adjustments so carried forward, shall amount to an increase or decrease of at least 1.0% in such Conversion Price; provided, however, that with respect to adjustments to be made to the Conversion Price in connection
with cash dividends paid by the Company pursuant to Section 4.05(a)(vi), the Company shall make such adjustments, regardless of whether such aggregate adjustments amount to 1.0% or more of the Conversion Price, no later than
September 15 of each calendar year. 
 (ii) Additionally, no adjustment to the Conversion Price or the Conversion Rate
shall be required: 
 (A) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for
the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan; 
 (B) upon the issuance of any shares of Common Stock or options or rights to purchase such shares pursuant to any present or future
employee, director or consultant benefit plan or program of, or assumed by, the Company or any of its Subsidiaries; 
  

 -46- 

 (C) upon the issuance of any shares of Common Stock pursuant to any option, warrant,
right or exercisable, exchangeable or convertible security not described in clause (ii) of this Section 4.05(b) and outstanding as of the Original Issue Date; 
 (D) in connection with a merger, consolidation or other transaction effected solely for the purpose of changing the Company’s
jurisdiction of incorporation to any other state within the United States; 
 (E) for a change in the par value of the Common
Stock; or 
 (F) for accrued and unpaid interest, if any. 
 (c) Increase in Conversion Rate due to Taxes. Subject to the Nasdaq Marketplace rules, the Company may make such increases in the Conversion Rate,
for the remaining term of the Notes or any shorter term, in addition to those required by clause (a) of this Section 4.05, as the Board of Directors of the Company considers advisable in order to avoid or diminish any income tax to
any holders of shares of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock or issuance of rights or warrants to purchase or subscribe for stock or from any event treated as such for income tax
purposes. The Company shall have the power to resolve any ambiguity or correct any error in this subsection (c) and its actions in so doing shall, absent manifest error, be final and conclusive. 
 Section 4.06. Notice of Adjustments of Conversion Rate. Whenever the Conversion Rate is adjusted pursuant to Section 4.05 hereof:

 (a) the Company shall compute the adjusted Conversion Rate in accordance with Section 4.05 hereof and shall
prepare an Officer’s Certificate setting forth (1) the adjusted Conversion Rate, (2) the clause of Section 4.05 pursuant to which such adjustment has been made, showing in reasonable detail the facts upon which such
adjustment is based, (3) the calculation of such adjustment and (4) the date as of which such adjustment is effective, and such certificate shall promptly be filed with the Trustee and with each Conversion Agent; and 
 (b) upon each such adjustment, a notice stating that the Conversion Rate has been adjusted and setting forth the adjusted Conversion Rate
shall be required, and as soon as practicable after it is required, such notice shall be provided by the Company to all Holders in accordance with Section 13.02. 
 Neither the Trustee nor any Conversion Agent shall be under any duty or responsibility with respect to any such certificate or the information and
calculations contained therein, except to exhibit the same to any Holder desiring inspection thereof at its office during normal business hours. 
 Section 4.07. Notice of Certain Corporate Action. In case the Company shall: 
 (a) distribute to all or
substantially all holders of the Common Stock rights, warrants or options entitling them to purchase, for a period expiring within forty-five (45) days of the declaration date for such distribution, Common Stock at less than the Current Market
Price of the Common Stock; or 
 (b) distribute to all or substantially all holders of Common Stock evidences of the
Company’s indebtedness, property or assets, including rights, warrants, options or other securities, which distribution has a per share value exceeding 10% of the Closing Sale Price of 

  

 -47- 

 
the Common Stock on the day preceding the declaration date for such distribution; then the Company shall deliver written notice to the Conversion Agent, and
shall deliver or cause its Agents to deliver, to all Holders in accordance with Section 13.02 hereof, at least ten (10) days prior to the ex-dividend date for such distribution, a notice of such distribution. 
 At any time that the Trustee is not also the Conversion Agent, the Company shall forthwith deliver a copy of any notice required pursuant to this
Section 4.07 to the Trustee. 
 Section 4.08. Cancellation of Converted Notes. All definitive Notes delivered for
conversion shall be delivered to the Trustee or its agent to be canceled by or at the direction of the Trustee, which shall dispose of the same as provided in Section 2.11 hereof. Upon conversions of beneficial interests in any Global
Note, the Trustee or the Custodian, at the direction of the Trustee, shall reduce the aggregate principal amount of outstanding Notes represented by such Global Note to reflect the conversion. 
 Section 4.09. Provision in Case of Reclassification, Consolidation, Merger or Sale of Assets. In the case of any consolidation or merger of the
Company with or into any other Person, any merger of another Person with or into the Company (other than a merger that does not result in any reclassification, conversion, exchange or cancellation of outstanding shares of Common Stock) or any
conveyance, sale or transfer of all or substantially all of the assets of the Company, the Company or the Person formed by such consolidation or resulting from such merger or which acquires such assets, as the case may be, shall notify the Trustee
and the Holders at least ten (10) days prior to the record date for such transaction, or if there is no record date, at least ten (10) Trading Days prior to the anticipated effective date for such transaction. The Company, or such
successor, purchasing or transferee corporation, as the case may be, as a condition precedent to such consolidation, merger, conveyance, sale or transfer, shall execute and deliver to the Trustee a supplemental indenture providing that the Holder of
each Note then outstanding shall have the right thereafter to convert Notes only into the kind and amount of securities, cash and other property receivable upon such consolidation, merger, conveyance, sale or transfer by a holder of the number of
shares of Common Stock into which such Notes might have been converted immediately prior to such consolidation, merger, conveyance, sale or transfer. Such supplemental indenture shall provide for adjustments of the Conversion Rate and Conversion
Price which shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Rate and Conversion Price provided for in this Article Four. If, in the case of any such consolidation, merger, conveyance, sale or transfer,
the securities, cash and other property receivable thereupon by a holder of Common Stock include shares of stock or other securities and property of a Person other than the successor, purchasing or transferee corporation, as the case may be, in such
consolidation, merger, conveyance or sale, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders as the Company’s Board of Directors
shall reasonably consider necessary by reason of the foregoing. 
 In the event holders of Common Stock have the opportunity to elect the
form of consideration to be received in such transaction, then from and after the effective date of such transaction, the Notes shall be convertible into the consideration that a majority of the holders of Common Stock who made such an election
received in such transaction. The Company will notify holders and the Trustee as promptly as practicable following the date such transaction is publicly announced but in no event less than fifteen (15) days prior to the anticipated effective
date of such transaction. The above provisions of this Section 4.09 shall similarly apply to successive consolidations, mergers, conveyances, sales or transfers. Notice of the execution of such a supplemental indenture shall be given by
the Company to the Holder of each Note as provided in Section 13.02 hereof promptly upon such execution. 
  

 -48- 

 Neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the
correctness of any provisions contained in any such supplemental indenture relating either to the kind or amount of shares of stock or other securities or property or cash receivable by Holders of Notes upon the conversion of their Notes after any
such consolidation, merger, conveyance, transfer, sale or lease or to any such adjustment, but may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, an Opinion of Counsel with respect
thereto, which the Company shall cause to be furnished to the Trustee upon request. 
 Section 4.10. Conversion Prior to October 1,
2010. In addition to the conversion shares and cash for fractional shares described herein, in the event a Holder elects to convert Notes prior to October 1, 2010, such Holder shall be entitled to receive a make-whole premium. This amount
will consist of the present value of all required interest payments on the Notes as if paid in cash from the date of such conversion through October 1, 2010 (including any accrued but unpaid interest), computed using a discount rate equal to
the Reinvestment Yield determined on the date of conversion (the “Conversion Make-Whole Amount”). The Company shall have 30 days from the date of conversion to pay the Conversion Make-Whole Amount. 
 Such payment shall be payable, at the Company’s option, in cash, shares of the Company’s Common Stock, or a combination of cash and shares. Any
such shares of the Company’s Common Stock will be valued at the volume weighted average closing sale prices of such Common Stock on the OTC Bulletin Board for the 10 consecutive trading days ending the last trading day before the Holder
delivers a notice of such conversion and the number of shares of the Company’s Common Stock to be delivered to Holders in satisfaction of such stock payment election will be at a 10% discount to the stock price. 
 Section 4.11. Fundamental Change. In case of a transaction described in the definition of Fundamental Change, the Company shall provide notice of
such Fundamental Change to all record Holders of Notes on a date (the “Fundamental Change Notice Date”) that is within 10 trading days after the effective date of the Fundamental Change (the “Effective Date”). If a
Fundamental Change occurs on or prior to October 1, 2010, the Company shall pay to Holders a make-whole premium equal to the Coupon Make Whole less all interest payments paid to the date of the Fundamental Change. If a Fundamental Change occurs
after October 1, 2010, the Company shall pay to Holders a make-whole premium equal to 7.0%. Holders shall be entitled to the make-whole premium as set forth above so long as they have converted their Notes into Common Stock on or prior to the
date of the Fundamental Change. The Company shall pay to the Holders any make-whole amount due to Holders hereunder within five business days of the Fundamental Change. 
 Section 4.12. Responsibility of Trustee for Conversion Provisions. The Trustee, subject to the provisions of Section 8.01 hereof, and any Conversion Agent, shall not at any time be under any duty or
responsibility to any Holder to determine whether any facts exist which may require any adjustment of the Conversion Rate or Conversion Price, or with respect to the nature or extent of any such adjustment when made, or with respect to the method
employed, herein or in any supplemental indenture provided to be employed, in making the same, or whether a supplemental indenture need be entered into. Neither the Trustee, subject to the provisions of Section 8.01 hereof, nor any
Conversion Agent, shall be accountable with respect to the validity or value (or the kind or amount) of any Common Stock, or of any other securities or property or cash, which may at any time be issued or delivered upon the conversion of any Note;
and it or they do not make any representation with respect thereto. Neither the Trustee, subject to the provisions of Section 8.01 hereof, nor any Conversion Agent, shall be responsible for any failure of the Company to make or calculate
any cash payment or to issue, transfer or deliver any shares of Common Stock or share certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion; and the Trustee, subject to the provisions of
Section 8.01 hereof, and any Conversion Agent, shall not be responsible for any failure of the Company to comply with any of the covenants of the Company contained in this Article 4.

 ARTICLE FIVE 
 Covenants 
 Section 5.01. 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 5.02. 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 5.03. Corporate Existence. Except as otherwise permitted by Articles Five,
Six, and Twelve 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 5.04. 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 5.05. 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 5.05 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 5.06. 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 5.08 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 13.02, 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. 
  

 -51- 

 Section 5.07. 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 5.08. 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 5.08 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. 
 In addition, following the effectiveness
of the shelf registration statement contemplated by the Registration Rights Agreement, 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 effectiveness of the shelf
registration statement contemplated by the Registration Rights Agreement, 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. 
  

 -52- 

 The receipt by the Trustee of any such reports and documents pursuant to this Section 5.08
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 5.09. 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 5.10. 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); 
 (c) make any payment (whether for principal, premium, if any, or interest) on, purchase, defease, redeem, prepay, decrease or otherwise acquire or retire for value, prior to any scheduled final maturity, scheduled repayment or scheduled
sinking fund payment, any 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”). 
 Notwithstanding the foregoing, if on a Record Date: 
 (i) a Default or an Event of Default shall not have occurred and be continuing; 
 (ii) the Company is able to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) in compliance with
Section 5.12; and 
  

 -53- 

 (iii) 50% of the aggregate amount of accrued and unpaid interest due on the Notes’
Interest Payment Date following such Record 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 such 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; plus  
 (C) without duplication of any amounts included in clause (iii)(B) above, 100% of the aggregate net cash proceeds of any equity contribution received by the Company from holders of the Company’s Capital Stock
subsequent to the Issue Date and on or prior to the Reference Date; 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 
 (F) any amounts previously paid
to the Holders of the 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 Interest Payment Date after payment of the Required Amount, in cash to the holders of the Notes. The Company may, subject to the other provisions of this Indenture, use any amounts remaining after such interest payment is made on the Notes for
any other lawful purpose. 
  

 -54- 

 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 (“Company Repurchases”); provided, however, that the aggregate amount of such Company
Repurchases 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 5.11. 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 $3.0 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 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 $6.0 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. 
  

 -55- 

 (b) The restrictions set forth in paragraph (a) of this covenant shall not apply to:

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 5.12. Limitation on Incurrence of Additional Indebtedness. 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 2.0 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 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.

 Section 5.13. 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 Senior Secured Notes Indenture, the Collateral Agreements (as defined in the Senior Secured 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; 
 (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 5.12 (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). 
  

 -57- 

 Section 5.14. 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: 
 (1) execute and deliver to the Trustee a supplemental indenture pursuant to which such Domestic Restricted Subsidiary shall
unconditionally guarantee on a senior secured subordinated 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 5.15. Redemption upon Change of Control. 
 (a) In addition to the rights described under Section 4.11, upon the occurrence of a Change of Control (regardless of whether such Change of Control constitutes a Fundamental Change), 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 5.15 and that all Notes tendered and not withdrawn shall be accepted for payment; 
  

 -58- 

 (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. 
 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 5.15, the Trustee shall act as the Paying Agent.

  

 -59- 

 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 5.15. 
 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 5.15, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this
Section 5.15 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 5.15 and purchases all Notes validly tendered and not withdrawn
under such Change of Control Offer. 
 If the Change of Control constitutes a Fundamental Change, the notice to Holders of their redemption
rights and the required notice of the Fundamental Change may be combined into a single notice. 
 A Change of Control will be deemed to have
occurred at such time after the Issue Date when any Fundamental Change has occurred, or when any event has occurred that would constitute a Fundamental Change but for the fact that the triggering event is a Qualifying Transaction. 
 Prior to complying with any of the provisions of this Section 5.15, but in any event within 90 days following a Change of Control, the
Company will either repay all outstanding Senior Debt or obtain the requisite consents, if any, under all agreements governing outstanding Senior Debt to permit the repurchase of Notes required by this Section 5.15. 
 Notes (or portions thereof) purchased pursuant to a Change of Control Offer shall be cancelled and may not be reissued. 
 The agreements governing the Company’s outstanding Senior Debt currently prohibit the Company from purchasing any Notes, and also provides that
certain change of control events with respect to the Company would constitute a default under these agreements or trigger an obligation to offer to repurchase Senior Debt governed thereby, as applicable. Any future credit agreements or other
agreements relating to Senior Debt to which the Company becomes a party may contain similar restrictions and provisions. In the event a Change of Control (as defined below) occurs at a time when the Company is prohibited from purchasing Notes, the
Company could seek the consent of its senior lenders to the purchase of Notes or could attempt to refinance the borrowings that contain such prohibition. If the Company does not obtain such a consent or repay such borrowings, the Company will remain
prohibited from purchasing Notes. In such case, the Company’s failure to purchase tendered Notes would constitute an Event of Default under this Indenture which would, in turn, constitute a default under such Senior Debt under the Credit
Agreement. In such circumstances, the subordination provisions in this Indenture would likely restrict payments to the Holders of Notes. 
  

 -60- 

 Section 5.16. 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 
 (3) the Company shall apply, or
cause such Restricted Subsidiary to apply, the Net Cash Proceeds relating to such Asset Sale within 365 days of receipt thereof either: 
 (a) to repay Senior Debt and, if the Senior Debt repaid is revolving Credit Indebtedness, to correspondingly and permanently reduce commitments in respect thereof; 
 (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 366th 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. 
  

 -61- 

 The Company may defer any Net Proceeds Offer until there is an aggregate unutilized Net Proceeds Offer
Amount equal to or in excess of $6.0 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 $6.0 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 6.01, 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. 
 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 5.17. Limitation on Liens. The Company will not, and will not
permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Liens (other than Permitted Liens) of any kind securing any Indebtedness 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) unless the Notes or such Guarantee, as the case may be, is equally and ratably secured with the obligations so secured until such time as those obligations are no longer secured by a Lien; provided that, in any case involving
a Lien securing subordinated Indebtedness of the Company, that Lien is subordinated to the Lien securing the Notes to the same extent that subordinated Indebtedness is subordinated to the Notes. 
 Section 5.18. 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 5.19. 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 

  

 -62- 

 
and any Investment in such Person remaining after giving effect to such issuance or sale would have been permitted to be made under Section 5.10
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 5.16. 
 Section 5.20. 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 5.21. 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 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 5.22. 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; 
  

 -63- 

 (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. 
 Section 5.23. 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 Senior
Priority Claims, such Mortgage, amendment or supplement must be delivered to the Collateral Agent at the same time as such grant to secure Senior Priority Claims. 
 Section 5.24. 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 5.22 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. 
  

 -64- 

 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 5.25. 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 5.22, 5.23 or 5.24 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 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 5.22, if such Other Collateral is real property. 
 Section 5.26. 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 5.27. Limitation on Capital Expenditures. The Company and its Restricted
Subsidiaries shall not make Capital Expenditures in excess of: 
 (1) the sum of (x) $7.0 million and (y) an amount
contractually required to prevent the loss of the Company’s rights to wells and acreage in the New Albany Shale not to exceed $2.0 million in the aggregate in the period from the Issue Date to December 31, 2007; 
 (2) the sum of (x) $18.0 million and (y) an amount contractually required to prevent the loss of the Company’s rights to
wells and acreage in the New Albany Shale not to exceed $2.0 million in the aggregate in the fiscal year ending December 31, 2008; and 
 (3) the sum of (x) $12.0 million and (y) an amount contractually required to prevent the loss of the Company’s rights to wells and acreage in the New Albany Shale not to exceed $2.0 million in the
aggregate in any fiscal year ending on or after December 31, 2009, 
 plus, with respect to clauses (2) and (3) above, up to $2.0 million of
unused amounts, if any, carried over from the preceding fiscal year; provided that, with respect to clauses (2) and (3) above, if the Company’s Consolidated EBITDA for the current fiscal year is projected to be equal to or greater
than $40.0 million, the Company and its Restricted Subsidiaries shall be permitted to make Capital Expenditures in an amount equal to 50% of the difference between Consolidated EBITDA in such fiscal year and $40.0 million. 
  

 -65- 

 Section 5.28. Limitation on Acquisitions. The Company and its Restricted Subsidiaries will not
(x) prior to the date that the Company’s Consolidated EBITDA for the previous 12 months is greater than $40.0 million, make Acquisitions totaling $5.0 million in the aggregate or (y) make Acquisitions in excess of $5.0 million unless
at the time of such Acquisition, without giving effect to the Acquisition, the Company’s Consolidated EBITDA for the previous 12 months is greater than $40.0 million. 
 Section 5.29. Holders’ Consent for Certain Actions. Notwithstanding anything to the contrary herein, without the consent of the Holders of a
majority in principal amount of the then outstanding Notes: 
 (1) the Company or any of its Restricted Subsidiaries will not
incur any Indebtedness (including Permitted Indebtedness) in an aggregate principal amount greater than or equal to $20.0 million in one or a series of related transactions; 
 (2) the Company or any of its Restricted Subsidiaries will not make any Permitted Investments in an amount greater than or equal to $10.0
million in one or a series of related transactions (other than Permitted Investments set forth in clauses (1)(b), (2), (3), (6), (8) or (10) of the definition thereof); 
 (3) the Company or any of its Restricted Subsidiaries will not make any Company Repurchases in an amount greater than or equal to $5.0
million in one or a series of related transactions; 
 (4) the Company or any of its Restricted Subsidiaries will not
consummate any Asset Sale for which the Company or its Restricted Subsidiaries receives aggregate consideration of greater than or equal to $10.0 million in one or a series of related transactions; 
 (5) the Company or any of its Restricted Subsidiaries will not create, incur, assume or suffer to exist any Liens (including Permitted
Liens) of any kind with respect to obligations that are greater than or equal to $20.0 million in one or a series of related transactions; 
 (6) the Company or any of its Restricted Subsidiaries 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; 
 (7) the Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into or permit to exist any 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; 
 (8) the Company and its Restricted Subsidiaries

the foregoing actions set forth in clauses (1)-(10) being referred to as “Consent Required Actions”). 
 In addition to
any other rights or remedies afforded to the Holders, should either the Company or its Restricted Subsidiaries not obtain the consent of the Holders for any Consent Required Action or the Holders not consent to any Consent Required Action and the
Company and its Restricted Subsidiaries proceed with any Consent Required Action, the Conversion Price then in effect will decrease by 50% and the interest rate on the Notes will increase by 300 basis points.

 Section 5.32. 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 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: 
 (1) swap contracts, collar contracts, floor contracts, and other similar derivative contracts for notional quantities of oil or gas;

 (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 5.33. No Layering of Debt. The Company will not incur any Indebtedness that is subordinated or
junior in right of payment to any Senior Debt of the Company and senior in right of payment to the Notes. No Guarantor will incur any Indebtedness that is subordinated or junior in right of payment to the Senior Debt of such Guarantor and senior in
right of payment to such Guarantor’s Guarantee. 
 Section 5.34. No Contingent Debt Tax Treatment. The Company agrees, and, by
acceptance of a Security, each beneficial holder of a Note will be deemed to have agreed, for U.S. federal income tax purposes, that (i) the Notes are contingent payment debt instruments as defined in Treasury Regulations
Section 1.1275-4(b), (ii) each beneficial holder shall be bound by the Company’s application of the Treasury regulations to the Notes, including the Company’s determination that the rate at which interest will be deemed to accrue
on the Notes for U.S. federal income tax purposes will be 14.254% compounded semi-annually, which is the rate comparable to the rate at which the Company would borrow on a noncontingent, nonconvertible basis with terms and conditions otherwise
comparable to the Notes, (iii) each beneficial holder shall use the projected payment schedule with respect to the Notes determined by the Company, as required by Treasury Regulations Section 1.1275-4(b)(4)(iv), to determine its interest
accruals and adjustments as provided in Treasury Regulations Section 1.1275-4(b)(4)(iv), to determine its interest accruals and adjustments as provided in Treasury Regulations Section 1.1275-4(b), and (iv) the Company and each
beneficial holder will not take any position on a tax return inconsistent with (i), (ii), or (iii), unless required by applicable law.

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 Section 6.01 and Section 5.16) 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: 
 (5) 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;

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 Section 6.01; and

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 6.01 hereof. 
 ARTICLE SEVEN 
 Default and Remedies 
 Section 7.01.
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, whether or not prohibited by the subordination provisions of this Indenture; 
 (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), whether or not prohibited by the subordination provisions of this Indenture; 
 (3) the failure to deliver Common Stock (together with cash instead of fractional shares) or cash when required to be delivered upon
conversion of a Note and the default continues for a period of 10 days, whether or not prohibited by the subordination provisions herein; 
 (4) 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 6.01, which will constitute an Event of Default with such notice requirement but without such passage of time requirement);

 (5) 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 $6.0 million or more at any time; 
  

 -71- 

 (6) one or more judgments in an aggregate amount in excess of $6.0 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; 
 (7) 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; 
 (8) 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; 
 (9) 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; 
 (10) 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 
 (11) 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 7.02. Acceleration. 
 (a) If an Event of Default (other than an Event of Default specified in Section 7.01, clause (7) or (8) 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. 

 

 -72- 

 (b) If an Event of Default specified in Section 7.01, clause (7) or (8) 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. 
 (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 7.01, clause (7) or (8) 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 7.03. 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 7.04.
Waiver of Past Defaults. Subject to Sections 2.09, 7.07 and 10.02, 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 7.02(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 7.05. 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 7.03. Subject to
Section 8.01 and 8.02(f), however, the Trustee or the Collateral Agent, as the case may be, may refuse to follow any direction (which direction, if sent to 

  

 -73- 

 
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 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 7.06. 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 7.07. 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 7.08. 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 7.01(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 

  

 -74- 

 
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 Section 5.01 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 8.07 hereof. 
 Section 7.09. 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 8.07.
The Company’ payment obligations under this Section 7.09 shall be secured in accordance with the provisions of Section 8.07. 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 7.10. Priorities. If the Trustee
collects any money or property pursuant to this Article Six, it shall pay out the money in the following order: 
 First: to the Trustee, the Collateral Agent, the Conversion Agent, the Paying Agent and the Registrar for amounts due under Section 8.07 (including payment of all compensation expense, all liabilities incurred and all
advances made by the Trustee, the Paying Agent, the Conversion Agent 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 7.10. 
 Section 7.11. 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 

  

 -75- 

 
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 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 7.11 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 7.06, or a suit by a Holder or Holders of more than 10% in principal amount of the outstanding Notes. 
 Section 7.12.
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 7.13. 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 7.14. 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 EIGHT 
 Trustee 
 Section 8.01. 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 Eight 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 
  

 -76- 

 (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

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 8.01.

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.

the extent such failure is directly caused by the failure of the Company to perform its obligations hereunder. 
 Section 8.02. Rights of
Trustee. Subject to Section 8.01: 
 (a) The Trustee may conclusively rely and shall be fully protected in acting or
refraining from acting upon any resolution, certificate, statement instrument, opinion, report, request direction, consent, order, bond, note or other paper or document believed by it to be genuine and to have been signed or presented by the proper

in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The written advice of the Trustee’s counsel or any Opinion of Counsel shall be full and complete authorization and protection from liability in respect of any
action taken, suffered or omitted by the Trustee hereunder in good faith and in reliance thereon.

attorneys and agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care and in good faith.

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 Five or Six 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.

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 13.02 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

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 8.03. 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 8.10 and 8.11, and the Trustee is subject to TIA Sections 310(b) and 311. 
 Section 8.04.

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. 
  

 -79- 

 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 8.05. 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 Six, 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 8.06. 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 8.07. 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 

  

 -80- 

 
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. 
 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 8.07) 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 8.07, 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 7.01(7) 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 8.07 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 8.08. 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 8.10; 
 (2) the Trustee is adjudged bankrupt or insolvent; 
  

 -81- 

 (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. 
 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 8.07. 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 8.07, 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 8.10, 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 8.07 shall continue for the benefit of the retiring
Trustee. 
 Section 8.09. 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. 
  

 -82- 

 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. 

Section 8.10. 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 the extent and in the manner provided by, and subject to the
provisions of, the TIA and this Indenture.

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 8.13. As of the Issue Date, the Company hereby appoints The Bank of
New York 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. 
  

 -83- 

 (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.

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 8.13, 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 8.13.

 (4) to make any change that would provide any additional rights or benefits to the Holders or that does not adversely affect the legal rights of any such Holder under this Indenture, the Notes, the Guarantees or the
Collateral Agreements; 
 (5) to comply with requirements of the Commission in order to effect or maintain the qualification
of this Indenture under the TIA; 
  

 -86- 

 (6) to conform the text of this Indenture, the Notes, the Guarantees, or the Collateral
Agreements to any provision of the “Description of Notes” in the Offering Circular to the extent that such provision was intended to be a verbatim recitation of a provision of this Indenture, the Notes, the Guarantees or the Collateral
Agreements; 
 (7) if necessary, in connection with any addition or release of Collateral permitted under the terms of this
Indenture or the Collateral Agreements; 
 (8) to allow any Subsidiary or any other Person to guarantee the Notes; 

(9) in the event that PIK Notes are issued in certificated form, to make appropriate amendments to this Indenture to reflect an
appropriate minimum denomination of certificated PIK Notes and establish minimum redemption amounts for certificated PIK Notes; 
 (10) to release a Guarantor as permitted by this Indenture and the relevant Guarantee; or 
 (11) to release
Collateral as permitted under the terms of this Indenture or the Collateral Agreements. 
 Notwithstanding the foregoing, in formulating its
opinion in regards to this Section 10.01 the Trustee or the Collateral Agent, as applicable, is entitled to rely on such evidence as it deems appropriate, including, without limitation, solely on an Opinion of Counsel. 
 Section 10.02. With Consent of Holders. Subject to Section 7.07, the Company, the Guarantors and the Trustee or the Collateral Agent,
as applicable, together, with the written consent of the Holder or Holders of a majority in aggregate principal amount of the then outstanding Notes (subject to Section 2.09), may amend, modify or supplement this Indenture, the Notes,
the Guarantees, the Registration Rights Agreement and the Collateral Agreements without notice to any other Holders. Subject to Section 7.07 and Section 2.09, the Holder or Holders of a majority in aggregate principal amount
of the then outstanding Notes may waive compliance by the Company with any provision of this Indenture, the Collateral Agreements or the Notes without notice to any other Holder. However, without the consent of: 
 (a) each Holder affected thereby, no amendment may: 
 (1) reduce amount of Notes whose Holders must consent to an amendment, supplement, modification or waiver of any provision of this Indenture, the Notes, the Guarantees or the Collateral Agreements; 
 (2) reduce the rate of or change or have the effect of changing the time for payment of interest, including defaulted interest, or
Additional Interest on any Notes; 
 (3) reduce the principal of or change or have the effect of changing the fixed maturity
of any Notes, or change the date on which any Notes may be subject to redemption or reduce the redemption price therefor; 
 (4) make any Notes payable in money other than that stated in the Notes; 
 (5) make any change in provisions of this
Indenture protecting the right of each Holder to receive payment of principal of, or premium, if any, interest and Additional Interest, if any, on, such Note on or after the due date thereof or to bring suit to enforce such payment, or permitting
Holders of a majority in principal amount of Notes to waive Defaults or Events of Default; 
  

 -87- 

 (6) amend, change or modify in any material respect the obligation of the Company to make
and consummate a Change of Control Offer after the occurrence of a Change of Control or make and consummate a Net Proceeds Offer with respect to any Asset Sale that has been consummated or modify any of the provisions or definitions with respect
thereto; 
 (7) subordinate the Notes or any Guarantee in right of payment to secure, any other Indebtedness of the Company or
any Guarantor other than as required in this Indenture; 
 (8) release any Guarantor from any of its obligations under its
Guarantee or this Indenture otherwise than in accordance with the terms of this Indenture; or 
 (9) make any change to
Section 10.01 or this Section 10.02; and 
 (b) the Holders holding at least 75% in aggregate
principal amount of the Notes, release all or substantially all of the Collateral otherwise than in accordance with the terms of this Indenture and the Collateral Agreements. 
 In addition, any amendment to, or waiver of, the provisions of this Indenture relating to subordination that adversely affects the rights of Holders will
require the consent of the Holders of at least 75% in aggregate principal amount of Notes then outstanding. 
 It shall not be necessary for
the consent of the Holders under this Section 10.02 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 10.02 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. 
 Section 10.03. 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 10.04. 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. 
  

 -88- 

 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 10.02, 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 10.05. 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 10.06. 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 Ten; 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 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
Ten 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. 
  

 -89- 

 Section 10.07. Conformity with Trust Indenture Act. Every supplemental indenture executed pursuant
to this Article Ten shall conform to the requirements of the TIA as then in effect. 
 ARTICLE ELEVEN 
 Subordination 
 Section 11.01.
Agreement to Subordinate. The Company agrees, and each Holder by accepting a Note agrees, that the Indebtedness evidenced by the Notes is subordinated in right of payment, to the extent and in the manner provided in this Article
Eleven, to the prior payment in full of all Senior Debt (whether outstanding on the date hereof or hereafter created, incurred, assumed or guaranteed) of the Company, and that the subordination is for the benefit of the holders of Senior Debt.

 Section 11.02. Liquidation; Dissolution; Bankruptcy. Upon any distribution to creditors of the Company in a liquidation or
dissolution of the Company or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Company or its property, in an assignment for the benefit of creditors or any marshaling of the Company’s assets and
liabilities: 
 (1) holders of Senior Debt will be entitled to receive payment in full in cash of all Obligations due in
respect of such Senior Debt (including interest after the commencement of any bankruptcy proceeding at the rate specified in the applicable Senior Debt) before the Holders of Notes will be entitled to receive any payment with respect to the Notes
(except that Holders of Notes may receive and retain Permitted Junior Securities and payments made from any trust created pursuant to Section 9 hereof); and 
 (2) until all Obligations with respect to Senior Debt (as provided in clause (1) above) are paid in full, any distribution to which
Holders would be entitled but for this Article Eleven will be made to holders of Senior Debt (except that Holders of Notes may receive and retain Permitted Junior Securities and payments made from the trusts created pursuant to
Section 9 hereof), as their interests may appear. 
 Section 11.03. Default on Designated Senior Debt. 
 (a) The Company may not make any payment or distribution to the Trustee or any Holder in respect of Obligations with respect to the Notes and may not
acquire from the Trustee or any Holder any Notes for cash or property (except in Permitted Junior Securities or from the trust described in Section 9 hereof) until all principal and other Obligations with respect to the Senior Debt have
been paid in full if: 
 (1) payment default on Designated Senior Debt occurs and is continuing beyond any applicable grace
period in the agreement, the indenture or other document governing such Designated Senior Debt; or 
 (2) any other default
occurs and is continuing on any series of Designated Senior Debt that permits holders of that series of Designated Senior Debt to accelerate its maturity and the Trustee receives a written notice of such default (a “Payment Blockage
Notice”) from the Company or the holders of any Designated Senior Debt. If the Trustee receives any such Payment Blockage Notice, no subsequent Payment Blockage Notice will be effective for purposes of this Section 11.03 unless
and until (A) at least 180 days have elapsed since the delivery of the immediately prior Payment Blockage Notice and (B) all scheduled payments of principal, interest and premium, if any, on the Notes that have come due have been paid in
full in cash. 
  

 -90- 

 No nonpayment default that existed or was continuing on the date of delivery of any Payment Blockage
Notice to the Trustee may be, or may be made, the basis for a subsequent Payment Blockage Notice, unless such default has been cured or waived for a period of not less than 180 days. 
 (b) The Company may and will resume payments on and distributions in respect of the Notes and may acquire them upon the earlier of: 
 (1) in the case of a payment default, upon the date on which such default is cured or waived, or 
 (2) in the case of a nonpayment default, upon the earlier of the date on which such nonpayment default is cured or waived or 179 days
after the date on which the applicable Payment Blockage Notice is received, unless the maturity of any Designated Senior Debt has been accelerated, 
 if
this Article Eleven otherwise permits the payment, distribution or acquisition at the time of such payment or acquisition. 
 Section
11.04. Acceleration of Notes. If payment of the Notes is accelerated because of an Event of Default, the Company will promptly notify holders of Senior Debt of the acceleration. 
 Section 11.05. When Distribution Must Be Paid Over. In the event that the Trustee or any Holder receives any payment of any Obligations with
respect to the Notes (other than Permitted Junior Securities and payments made from any trust described in Section 9 hereof) at a time when the payment is prohibited by these subordination provisions and the Trustee or such Holder, as
applicable, has actual knowledge that such payment is prohibited by Section 11.03 hereof, such payment will be held by the Trustee or such Holder, in trust for the benefit of, and will be paid forthwith over and delivered, upon written
request, to, the holders of Senior Debt as their interests may appear or their representative under the agreement, the indenture or other document (if any) pursuant to which Senior Debt may have been issued, as their respective interests may appear.

 With respect to the holders of Senior Debt, the Trustee undertakes to perform only those obligations on the part of the Trustee as are
specifically set forth in this Article Eleven, and no implied covenants or obligations with respect to the holders of Senior Debt will be read into this Indenture against the Trustee. The Trustee will not be deemed to owe any fiduciary duty
to the holders of Senior Debt, and will not be liable to any such holders if the Trustee pays over or distributes to or on behalf of Holders or the Company or any other Person money or assets to which any holders of Senior Debt are then entitled by
virtue of this Article Eleven, except if such payment is made as a result of the willful misconduct or gross negligence of the Trustee. 
 Section 11.06. Notice by Company. The Company will promptly notify the Trustee and the Paying Agent of any facts known to the Company that would cause a payment of any Obligations with respect to the Notes to violate this Article
Eleven, but failure to give such notice will not affect the subordination of the Notes to the Senior Debt as provided in this Article Eleven. 
 Section 11.07. Subrogation. After all Senior Debt is paid in full and until the Notes are paid in full, Holders of Notes will be subrogated (equally and ratably with all other Indebtedness pari passu
with the Notes) to the rights of holders of Senior Debt to receive distributions applicable to Senior 

  

 -91- 

 
Debt to the extent that distributions otherwise payable to the Holders of Notes have been applied to the payment of Senior Debt. A distribution made under
this Article Eleven to holders of Senior Debt that otherwise would have been made to Holders of Notes is not, as between the Company and Holders, a payment by the Company on the Notes. 
 Section 11.08. Relative Rights. This Article Eleven defines the relative rights of Holders of Notes and holders of Senior Debt. Nothing in
this Indenture will: 
 (1) impair, as between the Company and Holders of Notes, the obligation of the Company, which is
absolute and unconditional, to pay principal of, premium and interest on, the Notes in accordance with their terms; 
 (2)
affect the relative rights of Holders of Notes and creditors of the Company other than their rights in relation to holders of Senior Debt; or 
 (3) prevent the Trustee or any Holder of Notes from exercising its available remedies upon a Default or Event of Default, subject to the rights of holders and owners of Senior Debt to receive distributions and
payments otherwise payable to Holders of Notes. 
 If the Company fails because of this Article Eleven to pay principal of, premium or
interest on, a Note on the due date, the failure is still a Default or Event of Default. 
 Section 11.09. Subordination May Not Be
Impaired by Company. No right of any holder of Senior Debt to enforce the subordination of the Indebtedness evidenced by the Notes may be impaired by any act or failure to act by the Company or any Holder or by the failure of the Company or any
Holder to comply with this Indenture. 
 Section 11.10. Distribution or Notice to Representative. Whenever a distribution is to be
made or a notice given to holders of Senior Debt, the distribution may be made and the notice given to their Representative. 
 Upon any
payment or distribution of assets of the Company referred to in this Article Eleven, the Trustee and the Holders of Notes will be entitled to rely upon any order or decree made by any court of competent jurisdiction or upon any certificate of
such Representative or of the liquidating trustee or agent or other Person making any distribution to the Trustee or to the Holders of Notes for the purpose of ascertaining the Persons entitled to participate in such distribution, the holders of
Senior Debt and other Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article Eleven. 
 Section 11.11. Rights of Trustee and Paying Agent. Notwithstanding the provisions of this Article Eleven or any other provision of this
Indenture, the Trustee will not be charged with knowledge of the existence of any facts that would prohibit the making of any payment or distribution by the Trustee, and the Trustee and the Paying Agent may continue to make payments on the Notes,
unless the Trustee has received at its Corporate Trust Office at least five Business Days prior to the date of such payment written notice of facts that would cause the payment of any Obligations with respect to the Notes to violate this Article
Eleven. Only the Company or a Representative may give the notice. Nothing in this Article Eleven will apply to or impair the claims of, or payments to, the Trustee under or pursuant to Section 8.07 hereof. 
 The Trustee in its individual or any other capacity may hold Senior Debt with the same rights it would have if it were not Trustee. Any Agent may do the
same with like rights. 
  

 -92- 

 Section 11.12. Authorization to Effect Subordination. Each Holder of Notes, by the Holder’s
acceptance thereof, authorizes and directs the Trustee on such Holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article Eleven, and appoints the Trustee to act as
such Holder’s attorney-in-fact for any and all such purposes. If the Trustee does not file a proper proof of claim or proof of debt in the form required in any proceeding referred to in Section 7.09 hereof at least 30 days before
the expiration of the time to file such claim, the Representatives are hereby authorized to file an appropriate claim for and on behalf of the Holders of the Notes. 
 Section 11.13. Amendments. The provisions of this Article Eleven may not be amended or modified without the written consent of the holders of all Senior Debt. In addition, any amendment to, or waiver of,
the provisions of this Article Eleven that adversely affects the rights of the Holders of the Notes will require the consent of the Holders of at least 75% in aggregate principal amount of Notes then outstanding. 
 Section 11.14. Purchase Option. Following the acceleration of all of the Senior Notes, Holders may, at their sole expense and effort, upon notice
to the Company and under this Indenture, require the Senior Note Holders to transfer and assign to Holders, without warranty or representation or recourse, all (but not less than all) of the Obligations outstanding under the Senior Notes, the Senior
Notes Indenture and the Collateral Agreements (as defined in the Senior Note Indenture) that are owed to the holders of the Senior Notes (the “Noteholder Obligations”); provided that (x) such assignment may not conflict
with any law, rule or regulation or order of any court or other governmental authority having jurisdiction, and (y) Holders shall have paid to the Senior Notes Trustee, for the account of the Senior Note Holders, in immediately available funds,
an amount equal to 100% of the principal of such Indebtedness plus all such other Noteholder Obligations then outstanding. In order to effectuate the foregoing, the Company will calculate from time to time, the amount in cash that would be necessary
so to purchase the Noteholder Obligations. If the right set forth in this paragraph is exercised, the parties shall endeavor to close promptly thereafter but in any event within ten business days of the request set forth in the first sentence of
this paragraph. If Holders exercise the right set forth in this paragraph, it will be exercised pursuant to documentation mutually acceptable to each of the Senior Notes Trustee and the Trustee. 
 ARTICLE TWELVE 
 Guarantee

 Section 12.01. 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 7.01(7) or (8),
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 

  

 -93- 

 
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 12.03. 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 6.01 and 5.16. 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, 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 Seven 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 Seven, such obligations (whether or not due and payable) shall forthwith become due and payable by each
Guarantor for the purpose of this Guarantee. 
 Section 12.02. 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 5.16, or 
 (2) if the Company designates such Guarantor as an Unrestricted Subsidiary in accordance with the definition thereof, or 
 (3) 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 12.02. 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 Twelve. 
  

 -94- 

 Section 12.03. 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 12.05, 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 12.04. 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 5.16) 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;

 (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 or (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 6.01 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 6.01 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 12.04. 
 Section 12.05. 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. 
  

 -95- 

 Section 12.06. 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 12.07. Evidence of Guarantee. To evidence their guarantees to the Holders set forth in this Article Twelve, 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. 
 Each Guarantor hereby agrees that its Guarantee set forth in Section 12.01 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 12.08. 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.

Collateral (including the power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the
enforcement of, or compliance with, such enactment, rule or order would impair the security interest thereunder or be prejudicial to the interests of the Holders, the Trustee or the Collateral Agent). Notwithstanding the foregoing, the Collateral
Agent may, at the expense of the Company, request the direction of the Holders with respect to any such actions and upon receipt of the written consent of the Holders of at least a majority in aggregate principal amount of the outstanding Notes,

 14% Senior Subordinated Convertible Secured Note due 2013 
 1. Interest. Baseline
Oil & Gas Corp., a Nevada corporation (the “Company”), promises to pay interest on the principal amount of this Note at the rate per annum shown above. Interest on the Note will accrue from the most recent date on which
interest has been paid or, if no interest has been paid, from and including the Issue Date. The Company will pay interest semi-annually in arrears on each Interest Payment Date, commencing April 1, 2008; provided, however, that the
Company shall be entitled to issue PIK Notes under the Indenture pursuant to Sections 2.02 and 2.13 thereof in lieu of the payment of such interest in cash (provided that the aggregate principal amount thereof shall be equal to the amount of
such interest (rounded to the nearest whole dollar)). Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. The Company will pay interest on overdue principal at 1% per annum in excess of the above rate and
will pay interest on overdue installments of interest at such higher rate to the extent lawful. Additional Interest may accrue on this Note in certain circumstances pursuant to the Registration Rights Agreement and all references to
“interest” in this Note shall include any Additional Interest due on this Note pursuant to the terms of the Registration Rights Agreement. 
 2. Method of Payment. The Company shall pay interest on the Notes (except defaulted interest) to the Persons who are the registered Holders at the close of business on the Record Date immediately preceding the
Interest Payment Date even if the Notes are cancelled on registration of transfer or registration of exchange after such Record Date, and on or before such Interest Payment Date. Holders must surrender Notes to a Paying Agent to collect principal
payments. The Company shall pay principal and (to the extent not paid in the form of a PIK Note pursuant to Sections 2.02 and 2.13 of the Indenture) interest in money of the United States that at the time of payment is legal tender for payment of
public and private debts (“U.S. Legal Tender”). However, the Company may pay principal and interest by check payable in such U.S. Legal Tender. The Company may deliver any such interest payment to the Paying Agent or to a Holder at
the Holder’s registered address. 
 3. Paying Agent, Conversion Agent and Registrar. Initially, The Bank of New York (the
“Trustee”) will act as Paying Agent, Conversion Agent and Registrar. The Company may change any Paying Agent, Conversion Agent, Registrar or co-Registrar without notice to the Holders. 
 4. Indenture. The Notes and the Guarantees were issued under an Indenture, dated as of October 1, 2007 (the “Indenture”),
among the Company, the Trustee and the Collateral Agent. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Notes include those stated in the Indenture and those made part of the Indenture
by reference to the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb) (the “TIA”), as in effect on the date of the Indenture until such time as the Indenture is qualified under the TIA, and thereafter as in effect
on the date on which the Indenture is qualified under the TIA. Notwithstanding anything to the contrary herein, the Notes are subject to all such 

 
terms, and Holders of Notes are referred to the Indenture and the TIA for a statement of such terms. The Notes are senior subordinated obligations of the
Company. Each Holder, by accepting a Note, agrees to be bound by all of the terms and provisions of the Indenture, as the same may be amended from time to time. 
 5. Redemption. 
 (a) Optional Redemption. Semi-annually beginning on October 1, 2009, we
may redeem up to 25% of the principal amount of the Notes then outstanding at a redemption price of 100% of the aggregate principal amount thereof, plus accrued and unpaid interest thereon, to the date of redemption, only in the event the closing
price of shares of the Company’s Common Stock equals 150% or more of the Conversion Price then in effect for 20 of any 30 consecutive trading days, provided should we redeem any Notes prior to October 1, 2010 the Holders shall be entitled
to the make-whole premium set forth below under Section 4.10 as if the date of redemption were the date of conversion. 
 (b)
Mandatory Redemption. The Company is not required to make any mandatory redemption or sinking fund payments with respect to the Notes. 
 6. Notice of Redemption. Notice of redemption will be mailed by first-class mail at least 30 days but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at such Holder’s registered address
with a copy to the Trustee and Paying Agent. If fewer than all of the Notes are to be redeemed, at any time, selection of Notes for redemption will be made by the Trustee in compliance with the requirements of the principal national securities
exchange, if any, on which the Notes are listed, or, if the Notes are not so listed, on a pro rata basis, by lot or by such method as the Trustee deems to be fair and appropriate. Notes in denominations of $1,000 may be redeemed only
in whole. 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. 
 Except as set forth in the Indenture, if monies for the redemption of the Notes called for redemption shall have been deposited with the Paying Agent for
redemption on such Redemption Date sufficient to pay such Redemption Price plus accrued and unpaid interest and Additional Interest, if any, the Notes called for redemption will cease to bear interest from and after such Redemption Date, and the
only remaining right of the Holders of such Notes will be to receive payment of the Redemption Price plus accrued and unpaid interest and Additional Interest, if any, as of the Redemption Date upon surrender to the Paying Agent of the Notes
redeemed. 
 7. Offers to Purchase. Sections 5.15 and 5.16 of the Indenture provide that upon the occurrence of a Change
of Control and after certain Asset Sales, and subject to further limitations contained therein, the Company will make an offer to purchase certain amounts of the Notes in accordance with the procedures set forth in the Indenture. 
 8. Registration Rights. Pursuant to the Registration Rights Agreement among the Company, the Guarantors and the Initial Purchaser, the Company
will be obligated to file a Shelf Registration Statement (as defined in the Registration Rights Agreement). The 

 
Holders of the Notes shall be entitled to receive certain Additional Interest payments in the event such Shelf Registration Statement is not consummated and
upon certain other conditions, all pursuant to and in accordance with the terms of the Registration Rights Agreement. 
 9.
Conversion. Subject to and upon compliance with the provisions of Article 4 of the Indenture, at the option of the Holder thereof, any portion of the principal amount of this Note that is an integral multiple of $1,000 may be converted into
fully paid and non-assessable shares of Common Stock at the Conversion Rate, determined as provided in the Indenture, in effect at the time of conversion. The Holder may surrender Notes for conversion at the applicable Conversion Rate at any time
after ninety (90) days from the Original Issue Date until the close of business on the Business Day immediately preceding the final maturity date of the Notes. 
 Upon surrendering any Note for conversion, the Holder of such Note shall receive, in respect of each $1,000 principal amount of Notes, shares of Common Stock at an initial conversion rate of 1,389.00 shares per $1,000
principal amount of Notes (the “Conversion Rate”), which is based upon an initial Conversion Price of approximately $0.72 per share. The Conversion Rate (and Conversion Price) are subject to adjustment as described in the Indenture.

 The date on which a Holder of a Physical Note or holder of a beneficial interest in a Global Note completes the requirements of
Section 4.03(a) of the Indenture shall be deemed to be the date of conversion (the “Conversion Date”) for purposes of Article 4 of the Indenture. On and after the Conversion Date, the conversion by such Holder or holder, as set
forth in the Conversion Notice, shall become irrevocable. 
 In the event a Holder elects to exercise its right to convert its Notes pursuant
to Article 4 of the Indenture, and such election occurs prior to October 10, 2010, such Holder shall be entitled to receive a make-whole premium. This amount will consist of the present value of all required interest payments on the Notes as if
paid in cash from such conversion through October 10, 2010 (including any accrued but unpaid interest), computed using a discount rate equal to the Reinvestment Yield determined on the Conversion Date (the “Conversion Make-Whole
Amount”). The Company shall have thirty (30) days from the Conversion Date to pay the Conversion Make-Whole Amount. 
 10.
Denominations; Transfer; Exchange. The Notes are in registered form, without coupons, in denominations of $1,000 and integral multiples thereof. A Holder shall register the transfer of or exchange of Notes in accordance with the Indenture.
The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes, fees or similar governmental charges payable in connection therewith as permitted by the Indenture. The
Registrar need not register the transfer of or exchange of any Notes or portions thereof selected for redemption. 
 11. Persons Deemed
Owners. The registered Holder of a Note shall be treated as the owner of it for all purposes. 
 12. Unclaimed Money. If money for
the payment of principal or interest remains unclaimed for two years, the Trustee and the Paying Agent may pay the money without interest thereon back to the Company. After that, all liability of the Trustee and such Paying Agent with respect to
such money shall cease. 

 13. Discharge Prior to Redemption or Maturity. If the Company at any time deposits with the
Trustee U.S. Legal Tender or U.S. Government Obligations sufficient to pay the principal of and interest on the Notes to redemption or stated maturity and complies with the other provisions of the Indenture relating thereto, the Company will be
discharged from certain provisions of the Indenture and the Notes (including certain covenants, but excluding its obligation to pay the principal of and interest and Additional Interest, if any, on the Notes). 
 14. Amendment; Supplement; Waiver. Subject to certain exceptions, the Indenture, the Notes, the Guarantees and the Collateral Agreements may be
amended or supplemented with the written consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding, and any existing Default or Event of Default or noncompliance with any provision may be waived with the
written consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding. Without consent of any Holder, the parties thereto may amend or supplement the Indenture, the Notes, the Guarantees, or the Collateral
Agreements to, among other things, cure any ambiguity, defect or inconsistency, provide for uncertificated Notes in addition to or in place of certificated Notes, provide for the assumption of the Company’s or any Guarantor’s obligations
in accordance with Section 6.01 and Section 12.04 of the Indenture, make any other change that would provide any additional rights or benefits to the Holders that does not adversely affect the legal rights of any Holder of a
Note, to comply with the TIA, to allow for additional guarantees, if necessary, in connection with any addition or release of Collateral permitted under the Indenture or the Collateral Agreements, to release a Guarantor from its Guarantee as
permitted by the Indenture and to conform the text of the Indenture, the Collateral Agreements, the Notes and the Guarantees to the Offering Circular if necessary. 
 15. Restrictive Covenants. The Indenture imposes certain limitations on the ability of the Company and its Restricted Subsidiaries to, among other things, incur additional Indebtedness or grant Liens, make
payments in respect of their Capital Stock or certain Indebtedness, enter into transactions with Affiliates, create dividend or other payment restrictions affecting Subsidiaries, merge or consolidate with any other Person, sell, assign, transfer,
lease, convey or otherwise dispose of all or substantially all of its assets or adopt a plan of liquidation. Such limitations are subject to a number of important qualifications and exceptions. The Company must annually report to the Trustee on
compliance with such limitations. 
 16. Successors. When a successor assumes, in accordance with the Indenture, all the obligations
of its predecessor under the Notes, the Guarantees and the Indenture, the predecessor will be released from those obligations. 
 17.
Defaults and Remedies. If an Event of Default occurs and is continuing (other than certain events of bankruptcy involving the Company), the Trustee or the Holders of at least 25% in aggregate principal amount of outstanding Notes may declare
all the Notes to be due and payable in the manner, at the time and with the effect provided in the Indenture. Holders of Notes may not enforce the Indenture except as provided in the Indenture. The Trustee is not 

 
obligated to enforce the Indenture or the Notes unless it has received indemnity satisfactory to it. The Indenture permits, subject to certain limitations
therein provided, Holders of a majority in aggregate principal amount of the Notes then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of any continuing Default or Event
of Default (except a Default in payment of principal or interest) if it determines that withholding notice is in their interest. 
 18.
Subordination. The Indebtedness evidenced by the Notes is subordinated in right of payment, to the extent and in the manner provided in the Indenture, to the prior payment in full of all Senior Debt (whether outstanding on the date hereof or
hereafter created, incurred, assumed or guaranteed) of the Company. 
 19. Trustee Dealings with Company. Subject to the terms of the
TIA and the Indenture, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Company, its Subsidiaries or their respective Affiliates as if it were not the
Trustee. 
 20. No Recourse Against Others. No past, present or future affiliate, director, officer, employee, incorporator or holder
of any equity interests in the Company or a Guarantor or any direct or indirect parent corporation of the Company or a Guarantor, as such, will have any liability for any obligations of the Company or a Guarantor under the Notes, the Guarantees or
the Indenture, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for
issuance of the Notes. Each of the parties hereto acknowledge that such waiver may not be effective to waive liabilities under the federal securities laws. 
 21. Guarantees. Payment of principal and interest (including interest on overdue principal and overdue interest, if lawful), is unconditionally and irrevocably guaranteed, jointly and severally, by each of the
Guarantors. 
 22. Authentication. This Note shall not be valid until the Trustee or Authenticating Agent manually signs the
certificate of authentication on this Note. 
 23. Governing Law. THIS NOTE, THE INDENTURE, THE GUARANTEES AND THE COLLATERAL
AGREEMENTS (OTHER THAN THE MORTGAGES) SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO CONTRACTS MADE AND PERFORMED WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS.
EACH OF THE PARTIES HERETO AGREES TO SUBMIT TO THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS NOTE, THE INDENTURE, THE GUARANTEES AND THE COLLATERAL AGREEMENTS (OTHER THAN THE
MORTGAGES) OR THE TRANSACTIONS CONTEMPLATED BY THIS NOTE. 
 24. Abbreviations and Defined Terms. Customary abbreviations may be used
in the name of a Holder of a Note or an assignee, such as: TEN COM (= tenants in common), 

 
TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (=
Uniform Gifts to Minors Act). 
 25. Security. The Company’s and Guarantors’ obligations under the Notes are secured by
liens on the Collateral pursuant to the terms of the Collateral Agreements. The actions of the Trustee and the Holders of the Notes secured by such liens and the application of proceeds from the enforcement of any remedies with respect to such
Collateral are limited pursuant to the terms of the Collateral Agreements. 
 26. CUSIP Numbers. Pursuant to a recommendation
promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes as a convenience to the Holders of the Notes. No representation is made as to the accuracy of such numbers as
printed on the Notes and reliance may be placed only on the other identification numbers printed thereon.

Holder of a Note upon written request and without charge a copy of the Indenture. Requests may be made to: Baseline Oil & Gas Corp., 11811 North Freeway I-45, Suite 200, Houston, Texas 77060.
