reserve report),and decreased by, as of the date of determination, the estimated discounted future net revenue attributable to: 

  
 2 







 (A) estimated proved crude oil and natural gas reserves of such Person and

satisfy the obligations of such Person and its Restricted Subsidiaries with respect to Volumetric Production Payments on the schedules specified with respect thereto; and

 (2) the issuance of Equity Interests in any of the Company’s Restricted Subsidiaries or the sale of Equity Interests in any of its Restricted Subsidiaries (other than directors’ qualifying

provisions contained in the Appendix and the Notes shall constitute, and are hereby expressly made, a part of this Indenture and the Company, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such
terms and provisions and to be bound thereby. However, to the extent any such provision conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

 Section 2.02 Execution and Authentication.

 A Note shall not be valid until an authorized signatory of the Trustee manually signs the certificate of
authentication on the Note. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture. 
 On the Initial Issuance Date, the Trustee shall authenticate and deliver $350,000,000 of 12% First Priority Notes due 2018 and, at any time and from time to time thereafter, the Trustee shall authenticate

Paying Agent shall hold in trust for the benefit of Noteholders or the Trustee all money held by the Paying Agent for the payment of principal of, premium, if any, and interest on the Notes and shall notify the Trustee of any default by the Company
in making any such payment. If the Company or a Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund for the benefit of the Holders. The Company at any time may require a
Paying Agent (other than the Trustee) to pay all money held by it to the Trustee, and the Trustee may at any time during the continuance of any Event of Default under Section 6.01(a) or (b), upon written request to a Paying Agent,
require such Paying Agent to forthwith pay to the Trustee all sums so held in trust by such Paying Agent and, in each case, to account for any funds disbursed by such Paying Agent. Upon complying with this Section, the Paying Agent (if other than

registered form and shall be transferable only upon the surrender of a Note for registration of transfer. When a Note is presented to the Registrar or a co-registrar with a request to register a transfer, the Registrar shall register the transfer as
requested if the requirements of this Indenture and Section 8-401(a) of the Uniform Commercial Code are met. When Notes are presented to the Registrar with a request to exchange them for an equal principal amount of Notes of other
denominations, the Registrar shall make the exchange as requested if the same requirements are met. The Company may require payment of a sum sufficient to cover any taxes, assessments or other governmental charges in connection with any transfer or
exchange pursuant to this Section (other than any such transfer taxes, assessments or similar governmental charge payable upon exchange or transfer pursuant to Section 3.06, 4.10, 4.15 or 9.05). 

  
 41 








 Section 2.07 Replacement Notes. 

If a mutilated Note is surrendered to the Registrar or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully
taken, the Company shall issue and the Trustee shall authenticate a replacement Note if the requirements of Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies any other reasonable requirements of the Trustee. If
required by the Registrar or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of the Registrar, the Trustee and the Company to protect the Company, the Trustee, the Paying Agent and the Registrar from any loss
which any of them may suffer if a Note is replaced. The Company and the Trustee may charge the Holder for their expenses in replacing a Note. 
 Every replacement Note is an additional obligation of the Company and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.

 Section 2.08 Outstanding Notes. 
 The Notes outstanding at any time are all Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section as not outstanding.
Except as otherwise provided in TIA § 316(a), a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note. 
 If a Note is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser.

 If the Paying Agent (other than the Company or a Subsidiary thereof) holds in trust, in accordance with this Indenture, by
11:00 a.m. New York time, on a redemption date or other maturity date money sufficient to pay all principal, interest, premium, if any, and Additional Interest, if any, payable on that date with respect to the Notes (or portions thereof) to be
redeemed or maturing, as the case may be, then on and after that date such Notes (or portions thereof) shall cease to be outstanding and interest and Additional Interest, if any, on them shall cease to accrue. 

Section 2.09 Temporary Notes. 
 Until definitive Notes are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of definitive Notes but may
have variations that the Company considers appropriate for temporary Notes. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Notes and deliver them in exchange for temporary Notes. Holders of
temporary Notes shall be entitled to all of the benefits under this Indenture. 
 Section 2.10 Cancellation. 

The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Notes surrendered to them for registration of transfer, exchange, replacement or payment. The Trustee and no one else shall 

  
 42 








 
cancel and destroy (subject to the record retention requirements of the Exchange Act) all Notes surrendered for registration of transfer, exchange, replacement, payment or cancellation. Upon
written request, the Trustee will deliver a certificate of such cancellation to the Company unless the Company directs the Trustee to deliver canceled Notes to the Company instead. The Company may not issue new Notes to replace Notes it has
redeemed, paid or delivered to the Trustee for cancellation. 
 Section 2.11 Defaulted Interest. 

If the Company defaults in a payment of interest on the Notes, the Company shall pay defaulted interest at the rate specified in the
second paragraph of Section 4.01 (plus interest on such defaulted interest to the extent lawful) in any lawful manner. The Company may pay the defaulted interest to the Persons who are Noteholders on a subsequent special record date. The
Company shall fix or cause to be fixed any such special record date and payment date (which special record date shall not be less than 10 days prior to the related payment date) to the reasonable satisfaction of the Trustee and shall promptly mail
to each Noteholder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid. 

Section 2.12 CUSIP Numbers. 
 The Company in issuing the Notes may use “CUSIP” numbers and corresponding “ISINs” (if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers and
corresponding “ISINs” in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as
contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall
promptly notify the Trustee of any changes in “CUSIP” numbers. 
 Section 2.13 Issuance of Additional Notes. 

The Company shall be entitled, subject to its compliance with Section 4.09, to issue Additional Notes under this Indenture
which shall have identical terms as the Initial Notes issued on the Initial Issuance Date, other than with respect to the date of issuance, initial purchase price and the date from which initial interest begins to accrue. The Initial Notes issued on
the Initial Issuance Date, and any Additional Notes and all Exchange Notes issued in exchange therefor shall be treated as a single class for all purposes under this Indenture, including, without limitation, waivers, consents, directions,
declarations, amendments, redemptions and offers to purchase. 
 With respect to any Additional Notes, the Company shall set
forth in an Officers’ Certificate, which shall be delivered to the Trustee, the following information: 

(1) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture;

 (2) the issue price, the issue date (and the corresponding date from which interest shall accrue thereon and
the first interest payment date therefor) and the CUSIP 

  
 43 








 
number and any corresponding ISIN of such Additional Notes; provided, however, that any issuance of Additional Notes (i) is treated as part of the same issue as the Initial Notes within the
meaning of Treasury Regulation § 1.1275-1(f), (ii) is a qualified reopening of the Initial Notes within the meaning of Treasury Regulation § 1.1275-2(k), or (iii) is otherwise fungible with the Initial Notes for U.S.
federal income tax purposes, in the case of each of clauses (i), (ii) and (iii), so that such Additional Notes will trade as part of a single class with the Initial Notes (either initially or at such later time when the Additional Notes
are no longer Transfer Restricted Securities); and 
 (3) whether such Additional Notes shall be Transfer
Restricted Securities and issued in the form of Initial Notes as set forth in Exhibit 1 to the Appendix or shall be issued in the form of Exchange Notes as set forth in Exhibit 2 to the Appendix. 

ARTICLE 3 

REDEMPTION AND PREPAYMENT 

Section 3.01 Notices to Trustee. 
 If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee, at least five Business Days (unless a shorter

redemption shall occur, (ii) the redemption date, (iii) the principal amount of Notes to be redeemed, (iv) the redemption price, and (v) whether the Company requests that the Trustee give notice of such redemption. Any such

the Notes are to be redeemed at any time, the Trustee shall select the Notes to be redeemed among the Holders of the Notes as follows: (1) if the Notes are listed on any national securities exchange, in compliance with the requirements of the
principal national securities exchange on which the Notes are listed; or (2) if the Notes are not listed on any national securities exchange, on a pro rata basis or, in the case of Global Notes, the Trustee will select Notes for redemption
based on DTC’s method that most nearly approximates a pro rata selection unless otherwise required by law. In the event of partial redemption other than on a pro rata basis, the particular Notes to be redeemed shall be selected, not less than
five Business Days (unless a shorter period shall be agreeable to the Trustee) prior to the giving of notice of the redemption pursuant to Section 3.03, by the Trustee from the outstanding Notes not previously called for redemption.

 The Trustee 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. Notes and portions of Notes selected shall be in amounts of $2,000 or whole multiples of $1,000 in excess of $2,000; except that if all of the Notes of a Holder are to be
redeemed, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

 Section 3.03 Notice of Redemption. 

Subject to the provisions of Section 3.09 hereof, and except as otherwise provided in Section 3.08 hereof in
relation to a mandatory redemption, at least 30 days but not more than 60 days before a redemption date (except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a Legal
Defeasance, Covenant Defeasance or Discharge), the Company shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address (with a copy to the Trustee). Except
with respect to redemption pursuant to Section 3.08, notices of redemption may be conditional. 
 The notice shall
identify the Notes to be redeemed and shall state: 
 (a) the redemption date; 

(b) the redemption price or, if the redemption price is not then determinable, the manner in which it is to be
determined; 
 (c) 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 upon surrender of such Note, a new Note or Notes in a principal amount equal to the unredeemed portion shall be issued in the name of the applicable Holder upon cancellation of the original Note;

 (d) the name and address of the Paying Agent; 

(e) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; 

(f) that, unless the Company defaults in making such redemption payment, interest and Additional Interest, if any, on

 (g) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for
redemption are being redeemed; 
 (h) the CUSIP (or ISIN) number, if any, and that no representation is made as
to the correctness or accuracy of the CUSIP (or ISIN) number, if any, listed in such notice or printed on the Notes; and

modify such notice to the extent necessary to accord with the procedures of the Depository applicable to redemption. 
 At the
Company’s request, the Trustee shall give the notice of optional redemption in the Company’s name and at its expense; provided, however, that the Company shall have delivered to the Trustee, as provided in Section 3.01, an
Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the second preceding paragraph. 
 Section 3.04 Effect of Notice of Redemption. 
 Once notice of
redemption is mailed in accordance with Section 3.03 hereof, Notes (or portions thereof) called for redemption become irrevocably due and payable on the applicable redemption date at the applicable redemption price unless any condition
to the redemption set forth in the notice therefor shall not have been satisfied. If mailed in the manner provided for in Section 3.03, the notice of redemption shall be conclusively presumed to have been given whether or not a Holder
receives such notice. Failure to give timely notice or any defect in the notice shall not affect the validity of the redemption. 

Section 3.05 Deposit of Redemption Price. 
 Prior to 11:00 a.m., New York City time, on the redemption date, the Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary thereof is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 2.04 hereof) money sufficient in same day funds to pay the redemption price of and accrued interest and Additional Interest, if any, on all Notes to be redeemed on that date, it being
understood that the amount of money to be deposited by the Company in relation to a mandatory redemption pursuant to Section 3.08 shall take into consideration the amount of money deposited by the Escrow Agent with the Trustee or a
Paying Agent to fund such redemption. The Paying Agent shall promptly return to the Company any money deposited with the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of and accrued interest and
Additional Interest, if any, on all Notes to be redeemed. 
 If the Company complies with the provisions of the preceding
paragraph, on and after the redemption date, interest and Additional Interest, if any, shall cease to accrue on the Notes or the portions of Notes called for redemption whether or not such Notes are presented for payment, and the only remaining
right of the Holders of such Notes shall be to receive payment of the redemption price upon surrender to the Paying Agent of the Notes redeemed. If any Note called for redemption shall not be so paid upon surrender for redemption because of the
failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful, on any interest and Additional Interest, if any, not paid
on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof.

 Section 3.09 Offer to Purchase by Application of Excess Proceeds. 

In the event that, pursuant to Section 4.10 hereof, the Company shall be required to commence a Collateral Sale Offer, a
Second Priority Collateral Sale Offer or an Asset Sale Offer (each, an “Asset Disposition Repurchase Offer”), it shall follow the additional procedures specified below. 

The Asset Disposition Repurchase Offer shall remain open for a period of 20 Business Days following its commencement and not more than 30
Business Days, except to the extent that a longer period is required by Applicable Law (the “Offer Period”). No later than five Business Days after the termination of the Offer Period (the “Settlement Date”), the Company shall
purchase and pay for the aggregate principal amount of Notes, Second Priority Notes or Pari Passu Indebtedness, as applicable, required to be purchased pursuant to Section 4.10 hereof (the “Offer Amount”) or, if less than the
Offer Amount has been validly tendered (and not validly withdrawn), all Notes, Second Priority Notes or Pari Passu Indebtedness, as applicable, validly tendered (and not validly withdrawn) in response to the Asset Disposition Repurchase Offer.
Payment for any Notes so purchased shall be made in the manner prescribed in the Notes. 
 Upon the commencement of an Asset
Disposition Repurchase Offer, the Company shall send, by first class mail, a notice to each of the Holders, with a copy to the Trustee. The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant
to the Asset Disposition Repurchase Offer. The Asset Disposition Repurchase Offer shall be made to all Holders. The notice, which shall govern the terms of the Asset Disposition Repurchase Offer, shall state: 

(a) that the Asset Disposition Repurchase Offer is being made pursuant to this Section 3.09 and
Section 4.10 hereof and the length of time the Asset Disposition Repurchase Offer shall remain open, including the time and date the Asset Disposition Repurchase Offer will terminate (the “Termination Date”); 

(b) the Offer Amount, the purchase price and the purchase date; 

(c) that any Note not tendered or accepted for payment shall continue to accrue interest and Additional Interest, if any;

Termination Date; 
 (f) that Holders shall be entitled to withdraw their election if the Company or the Paying

 49 








 
telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing
his election to have such Note purchased; 
 (g) that, if the aggregate principal amount of Notes surrendered by
Holders and aggregate principal amount of Second Priority Notes surrendered by holders thereof and Pari Passu Indebtedness surrendered by holder or lenders, as applicable, collectively, exceeds the Offer Amount, the Trustee shall select the Notes to
be purchased from the amount allocated therefor on a pro rata basis on the basis of the aggregate principal amount of tendered Notes or, in the case of Global Notes, the Trustee will select Notes for purchase based on DTC’s method that most
nearly approximates a pro rata selection unless otherwise required by law (with such adjustments as may be deemed appropriate by the Trustee so that only Notes in denominations of $2,000, or integral multiples of $1,000 in excess of $2,000, shall be
purchased); and 
 (h) that Holders whose Notes were purchased only in part shall be issued new Notes equal in
principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess of $2,000. 

If any of the Notes subject to an Asset Disposition Repurchase Offer 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 repurchases. 
 Promptly after the
Termination Date, the Company shall, to the extent lawful, accept for payment Notes or portions thereof tendered pursuant to the Asset Disposition Repurchase Offer in the aggregate principal amount required by Section 4.10 hereof, and

amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company shall publicly announce the results of the Asset Disposition Repurchase
Offer on or before the Settlement Date.

Section 4.06 Stay, Extension and Usury Laws. 
 Each of the Company and 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, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and each of the Company and the Guarantors (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and

defeasance or other acquisition or retirement for value of Indebtedness that is subordinated in right of payment to the Notes or the Subsidiary Guarantees purchased, redeemed, defeased or otherwise acquired or retired for value in anticipation of

interest at the Stated Maturity thereof); 
 (4) make any Restricted Investment ; or 

(5) make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any
Second Priority Notes (other than (a) at the Stated Maturity thereof or (b) pursuant to a Change of Control Offer or a Second Priority Collateral Sale Offer) or Specified Junior Debt Issuances (other than at the Stated Maturity thereof or
pursuant to an Asset Sale Offer) (all such payments and other actions set forth in these clauses (1) through (5) being collectively referred to as “Restricted Payments”); 
 unless, at the time of and after giving effect to such Restricted Payment, no Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment and:

 (I) the Company would, at the time of such Restricted Payment immediately after giving pro forma effect
thereto as if the same had occurred at the beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in
Section 4.09; and 

  
 54 








 (II) such Restricted Payment, together with the aggregate amount of all
other Restricted Payments made by the Company and its Restricted Subsidiaries (excluding Restricted Payments permitted by clauses (2), (3), (4), (5), (8), (9), (11) and (12) of the next succeeding paragraph) since the date of this
Indenture, is less than the sum, without duplication, of: 
 (a) 50% of the Consolidated Net Income of the
Company for the period (taken as one accounting period) from the Measurement Date to the last day of the Company’s last fiscal quarter ending prior to the date of the Restricted Payment for which internal financial statements are in existence
at the time of such Restricted Payment (or, if such Consolidated Net Income for such period shall be a loss, minus 100% of such loss); plus 
 (b) 100% of the aggregate net cash proceeds and the Fair Market Value of any Capital Stock of Persons (other than the Company or an Affiliate of the Company) engaged primarily in the Oil and Gas Business
or any other assets that are used or useful in the Oil and Gas Business, in each case received by the Company after the date of this Indenture as a contribution to its common equity capital or from the issue or sale after the date of this Indenture
of Equity Interests of the Company (other than Disqualified Stock) or from the issue or sale after the date of this Indenture of convertible or exchangeable Disqualified Stock or convertible or exchangeable debt securities of the Company that have
been converted into or exchanged for such Equity Interests (other than Equity Interests (or Disqualified Stock or debt securities) sold to a Subsidiary of the Company) or received upon the exercise of any options, warrants or rights to purchase
Equity Interests (other than Disqualified Stock) of the Company, plus 
 (c) the amount equal to the net
reduction in Restricted Investments made by the Company or any of its Restricted Subsidiaries in any Person since the date of this Indenture resulting from:

Company, repayments of loans or advances or other transfers of assets (including by way of interest payments, dividend or distribution) by such Person to the Company or any Restricted Subsidiary of the Company; plus 

(ii) the redesignation of Unrestricted Subsidiaries as Restricted Subsidiaries or the merger or consolidation of an
Unrestricted Subsidiary with and into the Company or any Restricted Subsidiary (valued in each case as provided in the definition of “Investment”) not to exceed, in the case of any Unrestricted Subsidiary, the amount of Investments
previously made by the Company or any Restricted Subsidiary of the Company in such Unrestricted Subsidiary; plus 

  
 55 








 (iii) an amount equal to any amount included as a Restricted Payment
pursuant to clause (II) above on account of any guarantee entered into by the Company or any Restricted Subsidiary; to the extent that such guarantee has not been called upon and the obligation arising under such guarantee no longer exists or has
been reduced; plus 
 (iv) in the event the Company or any Restricted Subsidiary makes any Investment in a
Person that, as a result of or in connection with such Investment, becomes a Restricted Subsidiary or is merged or consolidated with the Company or a Restricted Subsidiary, an amount equal to the amount included as a Restricted Payment pursuant to
clause (II) above on account of the Company’s or any Restricted Subsidiary’s Investment in such Person prior to the time it became a Restricted Subsidiary or the time of such merger or consolidation; plus 

(d) the amount by which Indebtedness of the Company or its Restricted Subsidiaries is reduced on the Company’s
balance sheet upon the conversion or exchange (other than by a Subsidiary of the Company) subsequent to the date of this Indenture of any Indebtedness of the Company or its Restricted Subsidiaries convertible into or exchangeable for Equity
Interests of the Company (other than Disqualified Stock) (less the amount of cash, or the Fair Market Value of any other property, distributed by the Company upon such conversion or exchange), 

in the case of clauses (b) through (d) above, to the extent such amounts have not been included in Consolidated Net Income for
the applicable period. 
 The preceding provisions will not prohibit: 

(1) the payment of any dividend or distribution within 60 days after the date of its declaration, if at the date of
declaration the payment would have complied with the provisions of this Indenture; 
 (2) the purchase,
redemption, defeasance or other acquisition or retirement for value of any subordinated Indebtedness, Second Priority Notes or Specified Junior Debt Issuances of the Company or any Guarantor or of any Equity Interests of the Company in exchange for,

Company) of, Equity Interests of the Company (other than Disqualified Stock), with a sale being deemed substantially concurrent if such purchase, redemption, defeasance or other acquisition or retirement for value occurs not more than 120 days after
such sale; provided, however, that the amount of any such net cash proceeds that are utilized for any such purchase, redemption, defeasance or other acquisition or retirement for value will be excluded or deducted from clause (II) above; 


  
 56 








 (3) the purchase, redemption, defeasance or other acquisition or retirement
for value of subordinated Indebtedness, Second Priority Notes, Specified Junior Indebtedness or Disqualified Stock of the Company or any Guarantor with the net cash proceeds from a substantially concurrent incurrence of, or in exchange for,
Permitted Refinancing Indebtedness, with an incurrence of Permitted Refinancing Indebtedness being deemed substantially concurrent if such purchase, redemption, defeasance or other acquisition or retirement for value occurs not more than 120 days
after such incurrence;

Company to the holders of such Restricted Subsidiary’s Equity Interests (other than Disqualified Stock) on a pro rata basis or on a basis more favorable to the Company or a Restricted Subsidiary; 

(5) so long as no Default (other than a Reporting Default) or Event of Default shall have occurred and be continuing or
would be caused thereby, the purchase, redemption or other acquisition or retirement for value (other than for any Equity Interest) of any Equity Interests of the Company or any Restricted Subsidiary of the Company pursuant to any director, employee
or consultant equity subscription agreement or equity option agreement or other employee benefit plan or to satisfy obligations under any Equity Interests option plan or similar arrangement; provided, however, that the aggregate price paid for all
such purchased, redeemed, acquired or retired Equity Interests may not exceed $2.5 million in any calendar year (with any portion of such $2.5 million amount that is unused in any calendar year to be carried forward to successive calendar years and
added to such amount) plus, to the extent not previously applied or included, 
 (a) the cash proceeds received
by the Company or any of its Restricted Subsidiaries from sales of Equity Interests of the Company to employees, consultants or directors of the Company or its Affiliates that occur after the date of this Indenture (to the extent the cash proceeds
from the sale of such Equity Interests have not otherwise been applied to the payment of Restricted Payments by virtue of clause (II)(b) of the first paragraph of this Section 4.07); and 

(b) the cash proceeds of key man life insurance policies received by the Company or any of its Restricted Subsidiaries
after the date of this Indenture. 
 (6) any purchase, redemption, defeasance or other acquisition or retirement
for value of Indebtedness that is subordinated in right of payment to the Notes or a Subsidiary Guarantee pursuant to the provisions of such Indebtedness in the event of a Change of Control or an Asset Sale, in each case plus accrued and unpaid
interest thereon, but only if: 
 (a) in the case of a Change of Control, the purchase price therefor is not
greater than 101% of the principal amount of such Indebtedness and accrued and unpaid interest thereon, and the Company has first complied with and fully satisfied its obligations under Section 4.15; or 

  
 57 








 (b) in the case of an Asset Sale, the purchase price therefor is not greater
than 100% of the principal amount of such Indebtedness and accrued and unpaid interest thereon, and the Company has complied with and fully satisfied its obligations in accordance with Section 4.10; 

(7) the purchase, redemption or other acquisition or retirement for value of Equity Interests of the Company or any

upon the exercise or conversion of stock options, warrants or other convertible securities if such Equity Interests represent a portion of the exercise or conversion price thereof; 

(9) the purchase, redemption or other acquisition or retirement for value of any Equity Interests of the Company or any
Restricted Subsidiary of the Company held by any current or former officers, directors or employees of the Company or any of its Restricted Subsidiaries in connection with the exercise or vesting of any equity compensation (including, without
limitation, stock options, restricted stock and phantom stock) in order to satisfy any tax withholding obligation with respect to such exercise or vesting;

and payment of dividends payable pursuant to the terms (as of the date of this Indenture) of the Company’s Series C Preferred Stock outstanding on the date of this Indenture; 

(12) so long as no Default (other than a Reporting Default) or Event of Default shall have occurred and be continuing or
would be caused thereby, other Restricted Payments (excluding those in clause (5) of the first paragraph of this Section 4.07) in an aggregate amount not to exceed $25 million at any time outstanding since the date of this Indenture
(after giving effect to any dividends, interest payments, return of capital and subsequent reduction in the amount of any Investments made pursuant to this clause as a result of the repayment or other disposition thereof, in an amount not to exceed
the amount of such Investments previously made pursuant to in this clause); provided, however, that if any Investment pursuant to this clause (12) is made in any Person that is not a Restricted Subsidiary of the Company at the date of the
making of such Investment and such Person becomes a Restricted Subsidiary of the Company after such date, such 

  
 58 








 
Investment shall thereafter be deemed to have been made pursuant to clause (1) of the definition of “Permitted Investments” and shall cease to have been made pursuant to this
clause (12) for so long as such Person continues to be a Restricted Subsidiary. 
 The amount of all Restricted Payments
(other than cash) will be the Fair Market Value, on the date of the Restricted Payment, of the Restricted Investment proposed to be made or asset(s) or securities proposed to be paid, transferred or issued by the Company or such Restricted
Subsidiary, as the case may be, pursuant to such Restricted Payment, except that the amount of any non-cash Restricted Payment referred to in the preceding clause (1) will be the Fair Market Value on the date of declaration. The Fair Market
Value of any assets or securities that are required to be valued by this covenant will be determined by the method prescribed in the definition of such term, except that the Fair Market Value of any non-cash consideration received from an Affiliate
as a capital contribution for Equity Interests of the Company shall be determined in good faith by the Board of Directors of the Company in the case of amounts of $10 million or more, such determination to be based upon an opinion or appraisal
issued by an accounting, appraisal or investment banking firm of national standing. For purposes of determining compliance with this Section 4.07, in the event that a Restricted Payment meets the criteria of more than one of the
categories of Restricted Payments described in the preceding clauses (1)-(12) or as a Permitted Investment, the Company will be permitted to divide or classify (or later divide, classify or reclassify in whole or in part in its sole discretion)
such Restricted Payment in any manner that complies with this Section 4.07. 
 Section 4.08 Limitation on Dividend and Other
Payment Restrictions Affecting Subsidiaries. 
 The Company will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary of the Company to: 

(1) pay dividends or make any other distributions on its Capital Stock to the Company or any of its Restricted
Subsidiaries, or pay any Indebtedness or other obligations owed to the Company or any of its Restricted Subsidiaries; 
 (2) make loans or advances to the Company or any of its Restricted Subsidiaries; or 
 (3) sell, lease or transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries. 
 However, the preceding restrictions of this Section 4.08 will not apply to encumbrances or restrictions existing under or by reason of: 

(1) agreements (including those governing Existing Indebtedness) as in effect on the date of this Indenture and any
amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof; provided that the amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or
refinancings are no more restrictive, taken as a whole, with respect to such dividend, distribution and other payment restrictions than those contained in those agreements on the date of this Indenture, as determined by the Board of Directors of the
Company in its reasonable and good faith judgment; 

  
 59 








 (2) this Indenture, the Second Priority Notes Indenture, the Notes, the
Second Priority Notes, the Security Documents, the Second Priority Security Documents, the Intercreditor Agreement and the Subsidiary Guarantees; 
 (3) Applicable Law or similar restriction; 
 (4) any agreement or
instrument with respect to a Restricted Subsidiary that is not a Restricted Subsidiary of the Company on the date of this Indenture, in existence at the time such Person becomes a Restricted Subsidiary of the Company and not incurred in connection
with, or in contemplation of, such Person becoming a Restricted Subsidiary; provided that such encumbrances and restrictions are not applicable to the Company or any Restricted Subsidiary or the properties or assets of the Company or any Restricted
Subsidiary other than such Subsidiary which is becoming a Restricted Subsidiary; 
 (5) any agreement or
instrument governing any Permitted Acquisition Indebtedness, so long as such agreement or instrument (A) was not entered into in contemplation of the acquisition, merger or consolidation transaction related thereto, and (B) is not
applicable to any Person, or the properties or assets of any Person, other than the Person, or the properties or assets or Subsidiaries of the Person, subject to such acquisition, merger or consolidation, so long as the agreement containing such
restriction does not violate any other provision of this Indenture; 
 (6) instruments or agreements governing
Indebtedness of the Company or any of the Restricted Subsidiaries permitted to be incurred pursuant to an instrument or agreement entered into subsequent to the date of this Indenture in accordance with Section 4.09; either (a) the
encumbrance or restriction contained in the instrument or agreement governing such Indebtedness applies only in the event of a payment default or a default with respect to a financial covenant in such Indebtedness or agreement or (b) the Board
of Directors of the Company determines in good faith that any such encumbrance or restriction will not materially affect the Company’s ability to make principal or interest payments on the notes; 

(7) (i) customary non-assignment provisions in Hydrocarbon purchase and sale or exchange agreements, joint operating
agreements, or similar operational agreements or in licenses or leases entered into in the ordinary course of business, or (ii) in the case of clause (3) of the preceding paragraph, other encumbrances or restrictions in agreements or
instruments (including joint venture agreements, asset sale agreements, stock sale agreements and agreements of the type described in the definition of “Permitted Business Investments”) relating to specific assets or property (and not to
Indebtedness) that restrict generally the transfers of such assets or property, provided, however, that such other encumbrances or restrictions do not materially impair the ability of the Company to make scheduled payments on the notes when
due and in each case entered into in the ordinary course of business or customary in the Oil and Gas Business; 

  
 60 








 (8) Capital Lease Obligations, mortgage financings or purchase money
obligations, in each case for property acquired in the ordinary course of business or which is customary in the Oil and Gas Business that impose restrictions on that property purchased or leased of the nature described in clause (3) of the
preceding paragraph; 
 (9) any agreement for the sale or other disposition of a Restricted Subsidiary of the
Company that restricts distributions by that Restricted Subsidiary pending its sale or other disposition; 

(10) Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such
Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced, as determined by the Board of Directors of the Company in its reasonable
and good faith judgment; 
 (11) Liens securing Indebtedness otherwise permitted to be incurred under the
provisions of Section 4.12 that limit the right of the debtor to dispose of the assets subject to such Liens; 
 (12) restrictions on cash, Cash Equivalents or other deposits or net worth imposed by customers or lessors under contracts or leases entered into in the ordinary course of business or which are customary
in the Oil and Gas Business; 
 (13) Hedging Contracts permitted from time to time under this Indenture;

permitted by this Indenture) of any lender or other party to any Credit Facility (as a lender, letter of credit issuer or in any other capacity); and 
 (15) the issuance of preferred securities by a Restricted Subsidiary of the Company or the payment of dividends thereon in accordance with the terms thereof; provided that issuance of such preferred
securities is permitted pursuant to Section 4.09 and the terms of such preferred securities do not expressly restrict the ability of a Restricted Subsidiary of the Company to pay dividends or make any other distributions on its Equity
Interests (other than requirements to pay dividends or liquidation preferences on such preferred securities prior to paying any dividends or making any other distributions on such other Equity Interests). 

Section 4.09 Limitation on Incurrence of Indebtedness and Issuance of Preferred Stock. 

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume,
guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness, the Company will not issue any Disqualified Stock, and the Company will not permit any of its
Restricted Subsidiaries to issue any Disqualified Stock or preferred securities; provided, 

  
 61 








 
however, that the Company and any Guarantor may incur Indebtedness (other than any Specified Additional First Priority Notes), the Company may issue Disqualified Stock and any Guarantor may issue
Disqualified Stock or preferred securities, if the Fixed Charge Coverage Ratio for the Company’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such
additional Indebtedness is incurred or such preferred securities or Disqualified Stock is issued, as the case may be, would have been at least 2.25 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds
therefrom), as if the additional Indebtedness had been incurred or such preferred securities or Disqualified Stock had been issued, as the case may be, at the beginning of such four-quarter period. 

The first paragraph of this Section 4.09 will not prohibit the incurrence of any of the following items of Indebtedness or
the issuance of any Disqualified Stock or any preferred securities described below (collectively, “Permitted Debt”): 
 (1) the incurrence by the Company or any of the Restricted Subsidiaries of additional Indebtedness under one or more Credit Facilities, provided that, after giving effect to any such incurrence, the
aggregate principal amount of all Indebtedness outstanding under the Company and its Restricted Subsidiaries’ Credit Facilities incurred under this clause (1) does not exceed: 

(a) if the Company’s Adjusted Consolidated Net Tangible Assets determined as of the date of such incurrence are $2.0
billion or less, the greater of (i) $100 million and (ii) 7.5% of the Company’s Adjusted Consolidated Net Tangible Assets determined as of such date; 

(b) if the Company’s Adjusted Consolidated Net Tangible Assets determined as of the date of such incurrence are $3.0
billion or less, but exceed $2.0 billion, the greater of (i) $100 million and (ii) 10% of the Company’s Adjusted Consolidated Net Tangible Assets determined as of such date; and 

(c) if the Company’s Adjusted Consolidated Net Tangible Assets determined as of the date of such incurrence exceed
$3.0 billion, the greater of (i) $100 million and (ii) 15% of the Company’s Adjusted Consolidated Net Tangible Assets determined as of such date; 

(2) the incurrence by the Company or its Restricted Subsidiaries of the Existing Indebtedness not otherwise referred to
in this definition of “Permitted Debt”; 
 (3) the incurrence by the Company and the Guarantors of

Capital Lease Obligations, mortgage financings or purchase money obligations, in each case incurred for the purpose of financing all or any part of the purchase price or cost of design, installation, repair, replacement, construction or


  
 62 








 
improvement of property, plant or equipment used in the business of the Company or such Restricted Subsidiary (whether through the direct purchase of such assets or the Capital Stock of any
Person owning such assets (but no other material assets)) and related financing costs, and Attributable Debt in respect of Sale Leaseback Transactions, including all Permitted Refinancing Indebtedness incurred to extend, refinance, renew, replace,
defease, discharge, refund or otherwise retire for value any Indebtedness incurred pursuant to this clause (4), provided that after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness incurred pursuant to
this clause (4) and then outstanding does not exceed the greater of (a) $25 million and (b) 2.0% of the Company’s Adjusted Consolidated Net Tangible Assets determined as of the date of such incurrence; 

(5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange
for, or the net proceeds of which shall be used to extend, refinance, renew, replace, defease, discharge, refund or otherwise retire for value, in whole or in part, Indebtedness of the Company or any of its Restricted Subsidiaries (other than
intercompany Indebtedness) or Disqualified Stock of the Company, in each case that was permitted by this Indenture to be incurred pursuant to the first paragraph of this Section 4.09 or clauses (2), (3) and (12) of this
paragraph or this clause (5); 
 (6) the incurrence by the Company or any of its Restricted Subsidiaries of
intercompany Indebtedness between or among any of the Company and any of its Restricted Subsidiaries; provided, however, that: 
 (a) if the Company is the obligor on such Indebtedness and a Guarantor is not the obligee, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with
respect to the Notes, or if a Guarantor is the obligor on such Indebtedness and neither the Company nor another Guarantor is the obligee, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with
respect to the Subsidiary Guarantee of such Guarantor; 
 (b) (i) any subsequent issuance or transfer of
Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary of the Company and (ii) any sale or other transfer of any such Indebtedness to a Person that is neither the Company
nor a Restricted Subsidiary of the Company shall be deemed, in each case, to constitute an incurrence (as of the date of such issuance, sale or transfer) of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was
not permitted by this clause (6); and 
 (c) if a Foreign Subsidiary is the obligor on such Indebtedness
and the Company or a Domestic Subsidiary is the obligee, such Indebtedness must be evidenced by a promissory note or other instrument or agreement that is pledged in favor of the Collateral Agent pursuant to the Security Documents; 

  
 63 








 (7) the incurrence by the Company or any of its Restricted Subsidiaries of
obligations under Hedging Contracts; 
 (8)(a) the guarantee by the Company or any of its Guarantors of
Indebtedness of the Company or any of the Guarantors that was permitted to be incurred by the first paragraph of this Section 4.09; provided that if the Indebtedness being guaranteed is subordinated to the Notes, then the Subsidiary
Guarantee of that Guarantor shall be senior to its guarantee of such subordinated Indebtedness; and (b) the guarantee by the Company or any of its Restricted Subsidiaries of Indebtedness of the Company or any of its Restricted Subsidiaries that
was permitted to be incurred by another provision of this Section 4.09 other than the first paragraph hereof; provided that if the Indebtedness being guaranteed is subordinated to the notes, then the Subsidiary Guarantee of that
Restricted Subsidiary, if it is a Guarantor, shall be senior to its guarantee of such subordinated Indebtedness; 
 (9) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness relating to net gas balancing positions arising in the ordinary course of business and consistent with past
practice; 
 (10) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in respect
of bid, performance, surety, appeal and similar bonds issued for the account of the Company and any of its Restricted Subsidiaries in the ordinary course of business or which are customary in the Oil and Gas Business; 

(11) the issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its Restricted
Subsidiaries of any preferred securities; provided, however, that: 
 (a) any subsequent issuance or transfer of
Equity Interests that results in any such preferred securities being held by a Person other than the Company or a Restricted Subsidiary of the Company; and 
 (b) any sale or other transfer of any such preferred securities to a Person that is not either the Company or a Restricted Subsidiary of the Company shall be deemed, in each case, to constitute an
issuance (as of the date of such issuance, sale or transfer) of such preferred securities by such Restricted Subsidiary that was not permitted by this clause (11); 

(12) Permitted Acquisition Indebtedness; 

(13) the incurrence by the Company or its Restricted Subsidiaries of Indebtedness arising from the honoring by a bank or
other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds in the ordinary course of business, so long as such Indebtedness is covered within five Business Days; 

(14) the incurrence by the Company or its Restricted Subsidiaries of Indebtedness consisting of the financing of
insurance premiums in customary amounts consistent with the operations and business of the Company and the Restricted Subsidiaries; and 

  
 64 








 (15) the incurrence by the Company or any Guarantor of additional
Indebtedness other than Additional Priority Debt or the issuance by the Company of additional Disqualified Stock or the issuance by any Guarantor of preferred securities, provided that, after giving effect to any such incurrence or issuance, the
aggregate principal amount of all Indebtedness, Disqualified Stock and preferred securities incurred or issued under this clause (15) and then outstanding does not exceed the greater of (a) $75 million and (b) 5.0% of the
Company’s Adjusted Consolidated Net Tangible Assets determined as of the date of such incurrence or issuance. 
 For
purposes of determining compliance with this Section 4.09, in the event that an item of Indebtedness or Disqualified Stock or preferred securities meets the criteria of more than one of the categories of Permitted Debt described in
clauses (1) through (15) above, or is entitled to be incurred or issued pursuant to the first paragraph of this Section 4.09, the Company will be permitted to divide and classify (or later classify, reclassify or re-divide in
whole or in part in its sole discretion) such item of Indebtedness or Disqualified Stock or preferred securities in any manner that complies with this Section 4.09, subject to the limitations specified in the definition of “Existing
Indebtedness.” For purposes of determining any particular amount of Indebtedness under this covenant, guarantees of Indebtedness otherwise included in the determination of such amount shall not also be included except to the extent that such
Indebtedness exceeds such guarantee. 
 The accrual of interest, accrual of dividends, the accretion or amortization of original
issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness and the payment of dividends on Disqualified Stock or preferred securities in the form of additional shares of Disqualified Stock or preferred
securities will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock or preferred securities for purposes of this Section 4.09. 
 For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign
currency will be calculated based on the relevant currency exchange rate in effect on the date the Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such
Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and the refinancing would cause the applicable U.S. dollar-dominated restriction to be exceeded if calculated at the relevant currency exchange rate in
effect on the date of the refinancing, such U.S. dollar-dominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being
refinanced (plus all accrued and unpaid interest on such Indebtedness, and the amount of all fees, expenses and premiums incurred in connection therewith). Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that
the Company or any Restricted Subsidiary may incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Permitted Refinancing Indebtedness
incurred to refinance other Indebtedness, if incurred in a 

  
 65 








 
different currency from the Indebtedness being refinanced, will be calculated based on the currency exchange rate applicable to the currencies in which the Permitted Refinancing Indebtedness is
denominated that is in effect on the date of such refinancing. 
 Section 4.10 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 Restricted Subsidiary, as the case may be) receives consideration at least equal to the Fair
Market Value of the assets or Equity Interest issued or sold or otherwise disposed of; and 
 (2) (i) other than
with respect to Collateral Dispositions, at least 75% of the aggregate consideration to be received by the Company and its Restricted Subsidiaries in such Asset Sale (determined on the date of contractually agreeing to such Asset Sale) and any other
Asset Sale (other than Collateral Dispositions) since the date of this Indenture, on a cumulative basis, is in the form of cash or Cash Equivalents and (ii) with respect to Collateral Dispositions, 100% of the consideration to be received by
the Company or its Restricted Subsidiaries in such Asset Sale is in the form of cash. For purposes of this provision, except with respect to a Collateral Disposition, each of the following will be deemed to be cash: 

(a) any liabilities, as shown on the Company’s or any Restricted Subsidiary’s most recent balance sheet, of the
Company or such Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated in right of payment to the Notes or any Subsidiary Guarantee) that are assumed by the transferee of any such assets
pursuant to a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability; and 
 (b) any securities, notes or other obligations received by the Company or any Restricted Subsidiary from such transferee that are, within 90 days after the Asset Sale, converted by the Company or such
Restricted Subsidiary into cash or Cash Equivalents, to the extent of the cash received in that conversion. 
 provided that in
the case of any Asset Sale pursuant to a condemnation, appropriation or similar governmental taking, including by deed in lieu of condemnation, such Asset Sale shall not be required to satisfy the requirements of items (1) and (2) above.
Notwithstanding the preceding, the 75% limitation referred to above shall be deemed satisfied with respect to any Asset Sale to which such limitation applies in which the cash or Cash Equivalents portion of the consideration received therefrom,
determined in accordance with the preceding provision on an after-tax basis, is equal to or greater than what the after-tax proceeds would have been had such Asset Sale complied with the aforementioned 75% limitation. 

Within 365 days after the receipt of any Net Proceeds from an Asset Sale other than a Collateral Disposition, the Company (or the
applicable Restricted Subsidiary, as the case may be) may apply those Net Proceeds (except for Specified Asset Sale Proceeds that constitute Excess Proceeds) at its option to any combination of the following: 

  
 66 








 (1) to permanently prepay, repay, redeem, defease or purchase secured Senior
Debt (subject, in the case of the Second Priority Notes, to limitations in Section 4.07); 
 (2) to
invest in or acquire Additional Assets; or 
 (3) to make capital expenditures in respect of the Company’s
or its Restricted Subsidiaries’ Oil and Gas Business. 
 The requirement of clause (2) or (3) immediately above shall be deemed
to be satisfied if a bona fide binding contract committing to make the investment, acquisition or expenditure referred to therein is entered into by the Company or any of its Restricted Subsidiaries with a Person other than an Affiliate of the
Company within the time period specified above in this paragraph and such Net Proceeds are subsequently applied in accordance with such contract within six months following the date such agreement is entered into. 

Pending the final application of any Net Proceeds, the Company or any Restricted Subsidiary of the Company may invest the Net Proceeds in
any manner that is not prohibited by this Indenture. “Excess Proceeds” consist of any (i) Net Proceeds from Asset Sales other than Collateral Dispositions that are not applied or invested as provided in the preceding paragraph or
(ii) Specified Asset Sale Proceeds in excess of $100 million, to the extent of such excess. 
 When the aggregate amount of
Net Proceeds from all Collateral Dispositions (“Collateral Net Proceeds”) exceeds $10 million, the Company shall, within 60 days following the date on which such Collateral Net Proceeds first exceed such amount, use all Collateral Net
Proceeds to make an offer (the “Collateral Sale Offer”) to all Holders of Notes to purchase, on a pro rata basis, the maximum principal amount of Notes that may be purchased out of the Collateral Net Proceeds. After completion of the
Collateral Sale Offer, if there are any remaining Collateral Net Proceeds in excess of $10 million, the Company shall, within 60 days following the consummation of such Collateral Sale Offer, use all remaining Collateral Net Proceeds to make an
offer (the “Second Priority Collateral Sale Offer”) to all holders of Second Priority Notes, to purchase, on a pro rata basis, the maximum principal amount of Second Priority Notes that may be purchased out of such remaining Collateral Net
Proceeds. The offer price in any Collateral Sale Offer or Second Priority Collateral Sale Offer will be equal to 100% of principal amount plus accrued and unpaid interest, if any, and Additional Interest, if any, thereon to the Settlement Date,
subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the Settlement Date, and will be payable in cash. 

If the aggregate principal amount of Notes tendered into a Collateral Sale Offer exceeds the amount of Collateral Sale Proceeds allocated
for the purchase of such Notes, the Trustee will select the Notes to be purchased on a pro rata basis or, in the case of Global Notes, the Trustee will select Notes for redemption based on DTC’s method that most nearly approximates a pro rata
selection unless otherwise required by law (with such adjustments as may be deemed appropriate by the Trustee so that only Notes in denominations of $2,000, or integral multiples of $1,000 in excess of $2,000, shall be purchased). Upon surrender of
a Note that is repurchased in 

  
 67 








 
part, the Company shall issue in the name of the applicable Holder and the Trustee shall authenticate for such Holder at the expense of the Company a new Note equal in principal amount to the
non-repurchased portion of the Note surrendered. If any Collateral Net Proceeds remain after consummation of a Collateral Sale Offer and (if applicable) a corresponding subsequent Second Priority Collateral Sale Offer, the Company may use those
remaining proceeds for any purpose not otherwise prohibited by this Indenture. Upon completion of each Collateral Sale Offer and (if applicable) corresponding subsequent Second Priority Collateral Sale Offer, the amount of Collateral Net Proceeds
will be reset at zero. 
 On the 366th day after an Asset Sale other than a Collateral Disposition (or, at the Company’s
option, any earlier date), if the aggregate amount of Excess Proceeds then exceeds $10 million, the Company will make an offer (an “Asset Sale Offer”) to all Holders of Notes and, subject to limitations contained in
Section 4.07, to all holders of Second Priority Notes, as well as all holders of Pari Passu Indebtedness then outstanding, to purchase, on a pro rata basis, the maximum principal amount of Notes, Second Priority Notes and such Pari Passu
Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of principal amount plus accrued and unpaid interest and Additional Interest, if any, thereon to the Settlement Date,
subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the Settlement Date, and will be payable in cash. If the aggregate principal amount of Notes tendered
into such Asset Sale Offer exceeds the amount of Excess Proceeds allocated for the purchase of Notes, the Trustee will select the Notes to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Trustee so that
only Notes in denominations of $2,000, or integral multiples of $1,000 in excess of $2,000, shall be purchased) or, in the case of Global Notes, the Trustee will select Notes for purchase based on DTC’s method that most nearly approximates a
pro rata selection unless otherwise required by law (with such adjustments as may be deemed appropriate by the Trustee so that only Notes in denominations of $2,000, or integral multiples of $1,000 in excess of $2,000, shall be purchased). If any
Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. Upon surrender of a Note that is repurchased in part, the Company shall issue in
the name of the applicable Holder and the Trustee shall authenticate for such Holder at the expense of the Company a new Note equal in principal amount to the non-repurchased portion of the Note surrendered. Upon completion of each Asset Sale Offer,
the amount of Excess Proceeds will be reset at zero. 
 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 those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer or a Collateral Sale Offer. To the extent
that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.10, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its
obligations under such provisions by virtue of such compliance.

 Section 4.11 Limitation on Transactions with Affiliates. 

The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any properties or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any
Affiliate of the Company (each, an “Affiliate Transaction”), unless: 
 (1) the Affiliate Transaction
is on terms that are not less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person or, if in the
good faith judgment of the Company’s Board of Directors, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Company or the relevant Restricted Subsidiary
from a financial point of view; and 
 (2) the Company delivers to the Trustee: 

(a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate
consideration to or from an Affiliate in excess of $10 million, a resolution of the Board of Directors of the Company set forth in an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions
complies with this Section 4.11 and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by a majority of the disinterested members of the Board of Directors of the Company; and 

(b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate
consideration to or from an Affiliate in excess of $20 million, an opinion as to the fairness to the Company or such Restricted Subsidiary of such Affiliate Transaction or series of related Affiliate Transactions from a financial point of view
issued by an accounting, appraisal or investment banking firm of national standing. 
 The following items will not be deemed to
be Affiliate Transactions and, therefore, will not be subject to the provisions of the prior paragraph of this Section 4.11: 
 (1) any employment agreement or arrangement, equity award, equity option or cash or equity settled equity appreciation agreement or plan, employee benefit plan, officer or director indemnification
agreement, severance agreement, consulting agreement or other compensation plan or arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business or which is customary in the Oil and Gas Business,
and payments, awards, grants or issuances of securities pursuant thereto; 
 (2) transactions between or among
any of the Company and its Restricted Subsidiaries; 

  
 69 








 (3) transactions with a Person (other than an Unrestricted Subsidiary of the
Company) that is an Affiliate of the Company solely because the Company owns, directly or indirectly, an Equity Interest in, or otherwise controls, such Person or has nominated or appointed a person to the Board of Directors of that Person;

 (4) customary compensation, indemnification and other benefits made available to officers, directors,
employees or consultants of the Company or a Restricted Subsidiary of the Company, including reimbursement or advancement of out-of-pocket expenses and provisions of officers’ and directors’ liability insurance; 

(5) issuances of Equity Interests (other than Disqualified Stock) of the Company to, or receipt of capital contributions
from, Affiliates of the Company and any dividend or distribution payable in Equity Interests (other than Disqualified Stock) of the Company; 
 (6) any Permitted Investments or Restricted Payments that are permitted by Section 4.07; 
 (7) transactions between the Company or any of its Restricted Subsidiaries and any Person that would not otherwise constitute an Affiliate Transaction except for the fact that one director of such other
Person is also a director of the Company or such Restricted Subsidiary, as applicable; provided that such director abstains from voting as a director of the Company or such Restricted Subsidiary, as applicable, on any matter involving such other
Person; 
 (8) the existence of, and the performance of obligations of the Company or any of its Restricted
Subsidiaries under the terms of, any written agreement to which the Company or any of its Restricted Subsidiaries is a party on the date of this Indenture, as such agreements may be amended, modified, supplemented or replaced from time to time;
provided, however, that any amendment, modification, supplement or replacement entered into after the date of this Indenture will be permitted to the extent that its terms are not materially more disadvantageous, taken as a whole, to the Holders of
the Notes than the terms of the agreements in effect on the date of this Indenture (as conclusively evidenced by a Board Resolution); 
 (9) any transaction in which the Company or any of its Restricted Subsidiaries, as the case may be, delivers to the Trustee an opinion from an accounting, appraisal or investment banking firm of national
standing stating that such transaction is fair to the Company or such Restricted Subsidiary from a financial point of view or that such transaction meets the requirements of clause (1) of the preceding paragraph of this
Section 4.11; 
 (10) (a) guarantees by the Company or any of its Restricted Subsidiaries of
performance of obligations of the Company’s Unrestricted Subsidiaries in the ordinary course of business or which are customary in the Oil and Gas Business and (b) pledges by the Company or any Restricted Subsidiary of the Company of
Equity Interests in Unrestricted Subsidiaries for the benefit of lenders or other creditors of the Company’s Unrestricted Subsidiaries; 

  
 70 








 (11) any Affiliate Transaction with a Person in its capacity as a holder of
Indebtedness or Capital Stock of the Company or any Restricted Subsidiary of the Company if such Person is treated no more favorably than the other holders of Indebtedness or Capital Stock of the Company or such Restricted Subsidiary; 

(12) transactions with joint venture partners, customers, clients, suppliers or purchasers or sellers of goods or
services, or lessors or lessees of property, in each case in the ordinary course of business or which are customary in the Oil and Gas Business and otherwise in compliance with the terms of this Indenture similar to those contained in similar
contracts entered into by the Company or any Restricted Subsidiary and unrelated third parties, or if neither the Company nor any Restricted Subsidiary has entered into a similar contract with an unrelated third party, which are, in the aggregate
(taking into account all the costs and benefits associated with such transactions), not materially less favorable to the Company and its Restricted Subsidiaries than those that would have been obtained in a comparable transaction by the Company or
such Restricted Subsidiary with an unrelated third party, in the good faith determination of the Company’s Board of Directors or any executive officer of the Company involved in or otherwise familiar with such transaction; and 

(13) dividends and distributions to the Company and its Restricted Subsidiaries by any Unrestricted Subsidiary.

 Section 4.12 Limitation on Liens. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective (a) any Lien of any kind (other than
Permitted Liens) securing Indebtedness upon any of their property or assets other than the Collateral (whether now owned or hereafter acquired), unless the Notes or (in the case of such a Lien with respect to a Guarantor) the applicable Subsidiary
Guarantee is secured on an equal and ratable basis with (or (i) if such Lien secures Second Priority Notes Obligations, on a first-priority basis (in accordance with the Intercreditor Agreement) and (ii) if such Lien secures obligations
subordinated in right of payment to the Notes or such Subsidiary Guarantee, as the case may be, on a basis senior (to at least the same extent as the Notes are senior in right of payment) to) the obligations so secured until such time as such
obligations are no longer secured by a Lien or (b) any Lien of any kind securing Indebtedness upon any of the Collateral (whether now owned or hereafter acquired), other than the Notes and the Second Priority Notes. 

Any Lien on any property or assets of the Company or any of its Restricted Subsidiaries created for the benefit of the Holders of the
Notes pursuant to clause (a) of the preceding paragraph shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged at such time as there are no other Liens of any kind (other than Permitted
Liens) on such property or assets securing Indebtedness. 

  
 71 








 Section 4.13 Additional Subsidiary Guarantees. 

After the date of this Indenture, any Material Domestic Subsidiary that is not already a Guarantor shall become a Guarantor. In addition,
if, after the date of this Indenture, any Restricted Subsidiary of the Company that is not already a Guarantor guarantees any other Indebtedness of the Company or any Guarantor in excess of the De Minimis Guaranteed Amount, then that Subsidiary
shall become a Guarantor. Any such Subsidiary shall become a Guarantor by executing a supplemental indenture substantially in the form of Annex A hereto and delivering it to the Trustee within 60 days of the date on which it became a Material
Domestic Subsidiary or within 15 days of the date on which it guaranteed such Indebtedness, as the case may be, together with any Officers’ Certificate and Opinion of Counsel required by Section 9.06. 

Each Subsidiary Guarantee shall be released in accordance with Article 10. 

Section 4.14 Existence. 
 Except as otherwise permitted pursuant to the terms hereof (including consolidation and merger permitted by Section 5.01), the Company shall do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence, and the corporate, partnership, limited liability company or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as
the same may be amended from time to time) of the Company or any such Restricted Subsidiary; provided, however, that the Company shall not be required to preserve the existence of any of its Restricted Subsidiaries if the Company shall determine
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 and that the loss thereof is not adverse in any material respect to the Holders of the Notes.

 Section 4.15 Offer to Repurchase Upon Change of Control. 
 Within 30 days following the occurrence of a Change of Control, the Company shall make an offer (a “Change of Control Offer”) to repurchase all or any part (equal to $2,000 or an integral
multiple of $1,000 in excess of $2,000) of each Holder’s Notes at a purchase price in cash (the “Change of Control Payment”) equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest and
Additional Interest, if any, thereon to the date of purchase (the “Change of Control Purchase Date”), subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or
prior to the Change of Control Purchase Date. Within 30 days following a Change of Control, the Company shall mail a notice of the Change of Control Offer to each Holder and the Trustee describing the transaction that constitutes the Change of
Control and stating: 
 (a) that the Change of Control Offer is being made pursuant to this
Section 4.15 and that all Notes validly tendered and not withdrawn pursuant to the Change of Control Offer will be accepted for payment; 
 (b) the purchase price and the expiration date of the offer, which shall be no earlier than 30 days but no later than 60 days from the date such notice is mailed (the “Change of Control Offer
Expiration Date”); 

  
 72 








 (c) that the Change of Control Offer will expire as of the Change of Control
Offer Expiration Date and that the Company shall pay the Change of Control Purchase Price for all Notes purchased as of the Change of Control Offer Expiration Date promptly thereafter on the Change of Control Purchase Date; 

(d) that any Note not tendered will continue to accrue interest and Additional Interest, if any; 

(e) that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment
pursuant to the Change of Control Offer shall cease to accrue interest and Additional Interest, if any, after the Change of Control Purchase Date; 
 (f) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, properly endorsed for transfer, together with the form entitled
“Option of Holder to Elect Purchase” on the reverse of the Notes completed and such customary documents as the Company may reasonably request, to the Paying Agent at the address specified in the notice prior to the termination of the
Change of Control Offer on the Change of Control Offer Expiration Date; 
 (g) that Holders will be entitled to
withdraw their election if the Paying Agent receives, prior to the termination of the Change of Control Offer on the Change of Control Offer Expiration Date, a telegram, facsimile transmission or letter setting forth the name of the Holder, the
principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing its election to have the Notes purchased; and 
 (h) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be
equal to $2,000 in principal amount or an integral multiple of $1,000 in excess of $2,000. 
 If any of the Notes subject to a
Change of Control Offer 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 repurchases. Further, the Company shall 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 as a result of a Change of Control. To
the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.15, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached
its obligations under such provisions by virtue of such compliance. 
 Promptly after the Change of Control Offer Expiration
Date, the Company shall, to the extent lawful, accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer. Promptly thereafter on the Change of Control Purchase Date, the Company shall: 

  
 73 








 (i) deposit with the Paying Agent by 11:00 a.m., New York City time, an
amount equal to the Change of Control Payment in respect of all Notes or portions thereof so tendered; and 

(ii) 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 of Notes being purchased by the Company. 
 On the Change of Control
Purchase Date, the Paying Agent shall mail to each Holder of Notes properly tendered the Change of Control Payment for such Notes (or, if all the Notes are then in global form, make such payment through the facilities of the Depository) 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, if any; provided, however, that each such new Note will
be in a principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000. The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Purchase Date.

 The Change of Control provisions described in this Section 4.15 shall be applicable whether or nor any other
provisions of this Indenture are applicable. 
 Prior to complying with any of the provisions of this Section 4.15,
but in any event no later than the Change of Control Purchase Date, the Company or any Guarantor shall either repay all of its other outstanding Senior Debt or obtain the requisite consents, if any, under all agreements governing such Senior Debt to
permit the repurchase of Notes required by this Section 4.15. 
 The Company shall not be required to make a Change
of Control Offer following a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the price, at the time and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change
of Control Offer made by the Company and purchases all Notes properly tendered and not withdrawn under such Change of Control Offer or (2) notice of redemption of all Notes has been given pursuant to Sections 3.03 and 3.07, unless
there is a default in payment of the applicable redemption price. 
 A Change of Control Offer may be made in advance of a
Change of Control, and conditioned upon the occurrence of such Change of Control, if a definitive agreement is in place for such Change of Control at the time of making the Change of Control Offer. 

In the event that Holders of not less than 90% of the aggregate principal amount of the outstanding Notes accept a Change of Control
Offer and the Company (or the third party making the offer as provided above) purchases all of the Notes held by such Holders, the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice, given in compliance with
Section 3.03 (other than subsection (c) thereof) not more than 30 days following the purchase pursuant to such Change of Control Offer, to redeem all, but not less than all, of the Notes that remain outstanding following such
purchase at a purchase price equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued 

  
 74 








 
and unpaid interest on the Notes that remain outstanding, to the date of redemption (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest
payment date that is on or prior to such date of redemption). 
 Section 4.16 Payments for Consent. 

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration, whether by way of interest, fees or otherwise, to any Holder (or Beneficial Owner) of any Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture, the Notes, the Security
Documents or the Intercreditor Agreement unless such consideration is offered to be paid or is paid to all Holders (or Beneficial Owners) of the Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents
relating to such consent, waiver or amendment. 
 Section 4.17 Designation of Restricted and Unrestricted Subsidiaries. 

The Board of Directors of the Company may, other than during a Suspension Period, designate any Restricted Subsidiary of the Company
(other than any Subsidiary owning Collateral) to be an Unrestricted Subsidiary if that designation would not cause a Default and the other requirements for such designation prescribed in the definition of “Unrestricted Subsidiary” are
satisfied. If a Restricted Subsidiary of the Company is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary properly
designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under the first paragraph of Section 4.07 or represent
Permitted Investments, as determined by the Company. That designation shall only be permitted if the Investment would be permitted at that time and if the Subsidiary so designated otherwise meets the definition of an Unrestricted Subsidiary.

 The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary of the Company to be a Restricted
Subsidiary of the Company, provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be
permitted if (1) such Indebtedness is permitted under Section 4.09, calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference period, and (2) no Default (other than a
Reporting Default) or Event of Default would be in existence following such designation. 
 Section 4.18 Business Activities.

 The Company shall not, and shall not permit any Restricted Subsidiary to, engage in any business other than the Oil and Gas
Business, except to such extent as would not be material to the Company and its Restricted Subsidiaries taken as a whole. 

  
 75 








 Section 4.19 Suspended Covenants. 

From and after the first day (the “Suspension Date”) on which (1) the Notes have an Investment Grade Rating from both
Rating Agencies and (2) no Default has occurred and is continuing under this Indenture, the Company and its Restricted Subsidiaries will not be subject to the provisions of Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.18 and clause (d) of
Section 5.01 of this Indenture (collectively, the “Suspended Covenants”). 
 If at any date (each such date, a
“Reversion Date”) the credit rating of the Notes is downgraded from an Investment Grade Rating by either Rating Agency or a Default (other than with respect to the Suspended Covenants) occurs and is continuing, then the Suspended Covenants
will thereafter be reinstated and again become applicable. The period of time between the Suspension Date and the Reversion Date is referred to herein as the “Suspension Period.” Neither the failure of the Company or any of its
Subsidiaries to comply with a Suspended Covenant during a Suspension Period nor compliance by the Company or any of its Subsidiaries with any contractual obligation entered into in compliance with this Indenture during that period will constitute a
Default, Event of Default or breach of any kind under this Indenture, the Notes or the Subsidiary Guarantees. 
 Calculations
made after the Reversion Date of the amount available to be made as Restricted Payments under Section 4.07 will be made as though Section 4.07 had been in effect at all times since the Initial Issuance Date, including during
the Suspension Period. 
 The Company will provide the Trustee with prompt written notice upon the commencement of a Suspension
Period and of the occurrence of a Reversion Date. In addition, during any Suspension Period, the Board of Directors of the Company will not be permitted to designate any of its Subsidiaries as Unrestricted Subsidiaries. 

Section 4.20 After-Acquired Property. 
 Promptly following the acquisition by the Company or any Domestic Subsidiary at any time after expiration of the Escrow Period of any Specified Collateral Assets, the Company shall, or shall cause such
Domestic Subsidiary to, as applicable, (a) become a Pledgor under the US Pledge Agreement (to the extent not already a party thereto) by executing and delivering to the Collateral Agent a supplement to the US Pledge Agreement in the form
specified therein, whereby the Company or such Domestic Subsidiary, as applicable, shall grant a security interest to the Collateral Agent, for the benefit of the Secured Parties, in such Specified Collateral Assets (as well as such other assets
that constitute Collateral under the US Pledge Agreement), (b) execute and deliver such other Security Documents as the Collateral Agent may request in order to create and perfect security interests in such Specified Collateral Assets (as well
as such other assets that constitute Collateral under the US Pledge Agreement) in favor of the Collateral Agent, for the benefit of the Secured Parties, including Security Documents governed by the law of the jurisdiction of organization of any
First-Tier Foreign Subsidiary whose Capital Stock constitutes part of such Specified Collateral Assets or the jurisdiction of organization of the obligor under any promissory notes or other Indebtedness that constitutes part of such Specified
Collateral Assets, as applicable, and (c) take or cause to be taken such other actions (including delivering properly completed Uniform Commercial Code financing statements) as may be 

  
 76 








 
necessary or advisable in the opinion of the Collateral Agent to vest in the Collateral Agent, for the benefit of the Secured Parties, a first-priority perfected security interest in such
Specified Collateral Assets and to have such Specified Collateral Assets added to the Collateral and thereupon all provisions of this Indenture, the Security Documents and the Intercreditor Agreement relating to the Collateral shall be deemed to
relate to such Specified Collateral Assets to the same extent and with the same force and effect; provided, however, that the Company or such Domestic Subsidiary, as applicable, shall not be required to grant a security interest in the voting
Capital Stock of any First-Tier Foreign Subsidiary representing greater than 65% of the voting Capital Stock of such First-Tier Foreign Subsidiary. 
 Section 4.21 Further Assurances. 
 (a) The Company and the Domestic
Subsidiaries, at their own expense, shall do or cause to be done all acts and things that may be required, or that the Collateral Agent from time to time may reasonably request, to assure and confirm that the Collateral Agent holds, for the benefit
of the Secured Parties, duly created and enforceable and perfected Liens upon the Collateral (including any property or assets that are acquired or otherwise become Collateral after the expiration of the Escrow Period), in each case, as contemplated
by, and with the Lien priority required under, the Security Documents and the Intercreditor Agreement. 
 (b) Upon the
reasonable request of the Collateral Agent at any time and from time to time, the Company and the Domestic Subsidiaries, at their own expense, shall promptly execute, acknowledge and deliver such security documents, instruments, certificates,
notices and other documents, and take such other actions as may be reasonably required, or that the Collateral Agent may reasonably request, to create, perfect, protect, assure or enforce the Liens and benefits intended to be conferred, in each case
as contemplated by this Indenture, the Security Documents and the Intercreditor Agreement.

 81 








 Section 6.02 Acceleration. 

If any Event of Default occurs and is continuing, the Trustee, by notice to the Company, or the Holders of at least 25% in principal
amount of the then outstanding Notes, by notice to the Company and the Trustee, may declare all the Notes to be due and payable immediately. Upon any such declaration, the Notes shall become due and payable immediately, together with all accrued and
unpaid interest, Additional Interest, if any, and premium, if any, thereon. Notwithstanding the preceding, if an Event of Default specified in clause (i) or (j) of Section 6.01 hereof occurs, all outstanding Notes shall become
due and payable immediately without further action or notice, together with all accrued and unpaid interest, Additional Interest, if any, and premium, if any, thereon. The Holders of a majority in principal amount of the then outstanding Notes by
notice to the Trustee may on behalf of all of the Holders rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except with respect to nonpayment of
principal, interest, premium or Additional Interest, if any, that have become due solely because of the acceleration) have been cured or waived. 
 Section 6.03 Other Remedies. 
 If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment of principal of and interest, premium, if any, and Additional Interest, if any, on, the Notes or to enforce the performance of any provision of the Notes or this
Indenture. 
 The Trustee 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 or any Holder of a Note 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.
All remedies are cumulative to the extent permitted by law. 
 Section 6.04 Waiver of Past Defaults. 

Holders of a majority in principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of
the Notes waive (including, without limitation, in connection with a purchase of, or tender offer or exchange offer for, Notes) any existing Default or Event of Default and its consequences hereunder, except (i) a Default or Event of Default in
the payment of the principal of, or interest, premium, if any, or Additional Interest, if any, on the Notes or (ii) a Default or Event of Default in respect of a provision that under Section 9.02 cannot be amended without the
consent of each Holder affected. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture, but no such waiver shall extend to any
subsequent or other Default or impair any right consequent thereon. 
 Section 6.05 Control by Majority. 

Holders of a majority in principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding
for exercising any remedy available to the Trustee or exercising any trust or power conferred on it with respect to the Notes. However, the 

  
 82 








 
Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may
involve the Trustee in personal liability. In case an Event of Default has occurred and is continuing, prior to taking any action hereunder, the Trustee shall be entitled to satisfactory indemnification against all loss, liability and expenses
caused by the taking or not taking of such action. 
 Section 6.06 Limitation on Suits. 

No Holder may pursue any remedy hereunder with respect to this Indenture, the Subsidiary Guarantees or the Notes unless: 

(a) such Holder has previously given the Trustee notice of a continuing Event of Default; 

(b) the Holders of at least 25% in principal amount of the then outstanding Notes requested the Trustee to pursue the
remedy; 
 (c) such Holders have offered the Trustee reasonable security or indemnity against any loss,
liability or expense; 
 (d) the Trustee has not complied with such request within 60 days after the receipt of
the request and the offer of security or indemnity; and 
 (e) Holders of a majority in aggregate principal
amount of the then outstanding Notes have not given the Trustee a direction that is inconsistent with such request within such 60-day period. 

A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another
Holder of a Note. 
 Section 6.07 Rights of Holders of Notes to Receive Payment. 

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal of and interest,
premium, if any, and Additional Interest, if any, on, the Notes, on or after the respective due dates expressed in the Notes (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after
such respective dates, shall not be impaired or affected without the consent of such Holder. 
 Section 6.08 Collection Suit by
Trustee. 
 If an Event of Default specified in Section 6.01(a) or (b) occurs and is continuing, the
Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company and the Guarantors for the whole amount of principal of, interest, premium, if any, and Additional Interest, if any, remaining unpaid on
the Notes and interest on overdue principal and, to the extent lawful, interest and Additional Interest, if any, 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, its agents and counsel. 

  
 83 








 Section 6.09 Trustee is Authorized to File Proofs of Claim. 

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the
claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any
other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims, and any custodian in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be
secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes
or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

Section 6.10 Priorities. 
 If the Trustee collects any money pursuant to this Article, it shall pay out the money in the following order: 
 First: to the Trustee and the Collateral Agent, and their respective agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expense and
liabilities incurred, and all advances made, by the Trustee or the Collateral Agent and costs and expenses of collection incurred by the Trustee or the Collateral Agent; 

Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, interest, premium, if any, and
Additional Interest, if any, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, interest, premium, if any, and Additional Interest, if any, respectively; and 

Third: to the Company or to such party as a court of competent jurisdiction shall direct. 

The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10.


  
 84 








 Section 6.11 Undertaking for Costs. 

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or
omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable
attorneys’ fees, 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 does not apply to a suit by the Trustee, a suit by a Holder of a Note
pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes. 

Section 6.12 The Collateral Agent. 
 Whenever in the exercise of any remedy available to the Trustee or the exercise of any trust or power conferred on it with respect to the Notes, the Trustee may also direct the Collateral Agent in the
exercise of any of the rights and remedies available to the Collateral Agent pursuant to the Security Documents, and the Collateral Agent shall (subject to Section 11.07) comply with any such direction.

If a Default or Event of Default occurs and is continuing and if it is known to a Responsible Officer of the Trustee, the Trustee shall
mail to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, or interest, premium, or Additional Interest, if any, on, any Note,
the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes. 

Section 7.06 Reports by Trustee to Holders of the Notes. 
 Within 60 days after each June 1 beginning with the June 1 following the date of this Indenture, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a
brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The
Trustee also shall comply with TIA § 313(b). The Trustee shall also transmit by mail all reports as required by TIA § 313(c). 
 A copy of each report at the time of its mailing to the Holders of Notes shall be mailed to the Company and filed with the SEC and each stock exchange (if any) on which the Notes are listed in accordance
with TIA § 313(d). The Company shall promptly notify the Trustee when the Notes are listed on or de-listed from any stock exchange. 

Section 7.07 Compensation and Indemnity. 
 The Company shall pay to the Trustee from time to time such reasonable compensation as the Company and the Trustee may agree in writing for the Trustee’s acceptance of this Indenture and services
hereunder. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses
incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel. 

The Company and the Guarantors shall indemnify the Trustee, jointly and severally, against any and all losses, liabilities, damages,
claims or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company and the Guarantors
(including this Section 7.07) and defending itself against any claim (whether asserted by the Company, any Guarantor or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or
duties hereunder, except to the extent any such loss, liability, damage, claim or expense may be attributable to its negligence, bad faith or willful misconduct. The Trustee shall notify the Company and the Guarantors promptly of any claim for which
it may seek indemnity. Failure by the Trustee to so notify the Company and the Guarantors shall not relieve the Company or the Guarantors of their obligations hereunder. The Company and the Guarantors shall defend the claim and the Trustee shall
cooperate in the defense. The Trustee may have separate counsel and the Company and the Guarantors shall pay 

  
 88 








 
the reasonable fees and expenses of such counsel. Neither the Company nor any Guarantor need pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

 The obligations of the Company and the Guarantors under this Section 7.07 shall survive the satisfaction and
discharge of this Indenture and the resignation or removal of the Trustee. 
 To secure the Company’s and the
Guarantors’ payment obligations in this Section 7.07, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal, premium, if any, and
interest or Additional Interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture and the resignation or removal of the Trustee. 
 When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(i) or 6.01(j) hereof occurs, the expenses and the compensation for the services
(including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law. 
 The immunities, protections and exculpations available to the Trustee under this Indenture shall also be available to each Agent, and the Company’s obligations under this Section 7.07 to
compensate and indemnify the Trustee shall extend likewise to each Agent. 
 Section 7.08 Replacement of Trustee. 

A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor
Trustee’s acceptance of appointment as provided in this Section 7.08. 
 The Trustee may resign in writing upon
thirty (30) days notice at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of Notes of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the
Trustee and the Company in writing and may appoint a successor trustee with the consent of the Company. The Company may remove the Trustee if: 
 (a) the Trustee fails to comply with Section 7.10 hereof; 
 (b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; 

(c) a receiver, Custodian or public officer takes charge of the Trustee or its property; or 

(d) the Trustee becomes incapable of acting. 
 If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee
takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company. 

  
 89 








 If a successor Trustee does not take office within 30 days after the retiring Trustee
resigns or is removed, the retiring Trustee, the Company or the Holders of Notes of at least 10% of the principal amount of the then outstanding Notes may petition any court of competent jurisdiction, at the expense of the Company, for the
appointment of a successor Trustee. 
 If the Trustee, after written request by any Holder of a Note who has been a Holder of a
Note for at least six months, fails to comply with Section 7.10 hereof, such Holder of a Note may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, 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. The successor Trustee shall mail a notice of its succession to Holders
of the Notes. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07
hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s and the Guarantors’ obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee.

 Section 7.09 Successor Trustee by Merger, etc. 
 If the Trustee consolidates with, or merges or converts into, or transfers or sells all or substantially all of its corporate trust business or assets to, another corporation or banking association, the
successor corporation or banking association without any further act shall be the successor Trustee. As soon as practicable, the successor Trustee shall mail a notice of its succession to the Company and the Holders of the Notes. 

Section 7.10 Eligibility; Disqualification. 
 There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws
to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $100 million as set forth in its most recent published annual report of
condition. No obligor upon the Notes shall serve as a Trustee. 
 This Indenture shall always have a Trustee who satisfies the
requirements of TIA § 310(a)(1), (2) and (5). The Trustee is subject to TIA § 310(b). 
 Section 7.11
Preferential Collection of Claims Against the Company. 
 The Trustee is subject to TIA § 311(a), excluding any
creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein.

 ARTICLE 8 
 LEGAL DEFEASANCE AND COVENANT DEFEASANCE 
 Section 8.01 Option to Effect Legal Defeasance
or Covenant Defeasance. 
 The Company may, at the option of its Board of Directors evidenced by a resolution set forth in an
Officers’ Certificate, at any time, exercise their rights under either Section 8.02 or 8.03 hereof with respect to all outstanding Notes upon compliance with the conditions set forth below in this Article 8.

 Section 8.02 Legal Defeasance and Discharge. 
 Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company shall, subject to the satisfaction of the conditions set forth
in Section 8.04 hereof, be deemed to have discharged its obligations with respect to all outstanding Notes, the Security Documents and the Intercreditor Agreement and each Guarantor shall be deemed to have discharged its obligations with
respect to its Subsidiary Guarantee, the Security Documents and the Intercreditor Agreement on the date the conditions set forth in Section 8.04 below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal
Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, and each Guarantor shall be deemed to have paid and discharged its Subsidiary Guarantee (which in each case
shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in (a) and (b) below) and to have satisfied all its other obligations
under such Notes or Subsidiary Guarantee, this Indenture, the Security Documents and the Intercreditor Agreement (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for
the following provisions which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Notes to receive solely from the trust fund described in Section 8.04 hereof, and as more
fully set forth in such Section, payments in respect of the principal of and interest, premium, if any, and Additional Interest, if any, on, such Notes when such payments are due, (b) the Company’s obligations with respect to such Notes
under Article 2 and Section 4.02 hereof and the Appendix, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s and the Guarantors’ obligations in connection therewith and
(d) the Legal Defeasance and Covenant Defeasance provisions of this Article 8. Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding the prior
exercise of its option under Section 8.03 hereof. 
 Section 8.03 Covenant Defeasance. 

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the
Company shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from its obligations under the covenants contained in Article 4 (other than those in Sections 4.01,
4.02, 4.06, 4.14 and 4.19) and in clause (d) of Section 5.01 hereof on and after the date the conditions set forth in Section 8.04 are satisfied (hereinafter, “Covenant Defeasance”),
and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences 

  
 91 








 
of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be
deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Company and any Guarantor may omit to comply with and shall have no liability in respect of any term, condition
or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document
and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon
the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
Section 6.01(d) and Sections 6.01(f) through 6.01(h) hereof shall not constitute Events of Default. 

Section 8.04 Conditions to Legal or Covenant Defeasance. 
 In order to exercise either Legal Defeasance or Covenant Defeasance: 
 (a) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as
will be sufficient, in the opinion of a nationally recognized investment banking firm, appraisal firm or firm of independent public accountants, to pay the principal of, and interest, premium, if any, and Additional Interest, if any, on, the
outstanding Notes to the date of Stated Maturity or the applicable redemption date, as the case may be, and the Company must specify whether the Notes are being defeased to the date of Stated Maturity or to a particular redemption date; 

(b) in the case of an election under Section 8.02 hereof, the Company shall have delivered to the Trustee an
Opinion of Counsel reasonably acceptable to the Trustee confirming that: 
 (1) the Company has received a
ruling from, or a ruling has been published by, the Internal Revenue Service; or 
 (2) since the Initial
Issuance Date, there has been a change in the applicable federal income tax law, 
 in either case to the effect that, and based
thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the
same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 
 (c) in the case of an election under Section 8.03 hereof, the Company shall have delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Holders
of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would
have been the case if such Covenant Defeasance had not occurred; 

  
 92 








 (d) no Default or Event of Default shall have occurred and be continuing on
the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit pursuant to this Section 8.04 or the grant of Liens securing such borrowing); 

(e) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default
under, any material agreement or instrument (other than this Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; 

(f) the Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made
by the Company with the intent of preferring the Holders over the other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and 

(g) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating
that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 
 Section 8.05
Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions. 
 Subject to
Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee pursuant to Section 8.04 or 8.08 hereof in respect of the outstanding Notes shall be
held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company or any of its Subsidiaries acting as Paying Agent) as
the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, interest, premium, if any, and Additional Interest, if any, but such money need not be segregated from other funds except to
the extent required by law. 
 The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on
or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 or 8.08 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by
law is for the account of the Holders of the outstanding Notes. 
 Anything in this Article 8 to the contrary
notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the written request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 or 8.08 hereof
which, in the opinion of a nationally recognized investment banking, appraisal firm or firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under
Section 8.04(a) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance, Covenant Defeasance or Discharge, as the case may be. 

  
 93 








 Section 8.06 Repayment to the Company. 

Subject to applicable escheat and abandoned property laws, any money or non-callable Government Securities deposited with the Trustee or
any Paying Agent, or then held by the Company, in trust for the payment of the principal of, or interest, premium, if any, or Additional Interest, if any, on, any Note and remaining unclaimed for two years after such principal, interest, premium, if
any, or Additional Interest, if any, has become due and payable shall be paid to the Company on its written request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter be permitted to
look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money or non-callable Government Securities, and all liability of the Company as trustee thereof, shall thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, shall at the written request and expense of the Company cause to be published once, in the New York Times and The Wall Street Journal
(national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be
repaid to the Company. 
 Section 8.07 Reinstatement. 
 If the Trustee or Paying Agent is unable to apply any money or non-callable Government Securities in accordance with Section 8.05 hereof, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’ obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had
occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.05 hereof; provided, however, that, if the Company or
any Guarantor makes any payment of principal of, interest, premium, if any, or Additional Interest, if any, on, any Note following the reinstatement of its obligations, the Company or such Guarantor, as applicable, shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the money or Government Securities deposited with or held by the Trustee or Paying Agent. 
 Section 8.08 Discharge. 
 This Indenture shall be satisfied and
discharged and shall cease to be of further effect as to all Notes issued hereunder (except for (a) the rights of Holders of outstanding Notes to receive solely from the trust fund described in clause (b) of this Section 8.08,
and as more fully set forth in such clause (b), payments in respect of the principal of and interest, premium, if any, and Additional Interest, if any, on, such Notes when such payments are due, (b) the Company’s obligations with
respect to such Notes under Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.09 and 4.02 hereof and the Appendix and (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the
Company’s obligations in connection therewith), and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture with respect to all the Notes, when: 

  
 94 








 (1) either: 

(a) all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and
Notes for whose payment money has been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or 
 (b) all Notes that have not been delivered to the Trustee for cancellation have become due and payable or will become due and payable within one year by reason of the mailing of a notice of redemption or
otherwise, and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a
combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on the Notes not delivered to the
Trustee for cancellation for principal, accrued interest, premium, if any, and Additional Interest, if any, to the date of fixed maturity or redemption; 
 (2) no Default or Event of Default has occurred and is continuing on the date of the deposit or will occur as a result of the deposit (other than a Default or Event of Default resulting from the borrowing
of funds to be applied to such deposit or the grant of Liens securing such borrowing); 
 (3) such deposit will
not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is
bound; 
 (4) the Company and the Guarantors have paid or caused to be paid all other sums payable by them under
this Indenture; 
 (5) the Company has delivered irrevocable instructions to the Trustee to apply the deposited
money toward the payment of the Notes at fixed maturity or the redemption date, as the case may be; and 
 (6)
the Company has delivered (a) an Officers’ Certificate to the Trustee stating that all conditions precedent to satisfaction and discharge of this Indenture (“Discharge”) have been satisfied and (b) an Opinion of Counsel to
the Trustee stating that all conditions precedent to Discharge set forth in clauses (3) and (5) above have been satisfied.

 ARTICLE 9 
 AMENDMENT, SUPPLEMENT AND WAIVER 
 Section 9.01 Without Consent of Holders of Notes.

 Notwithstanding Section 9.02 of this Indenture, without the consent of any Holders of Notes, the Company, the
Guarantors, the Trustee and the Collateral Agent may amend or supplement this Indenture, the Security Documents (by the applicable parties thereto), the Intercreditor Agreement and the Notes in the following circumstances: 

(a) to cure any ambiguity, omission, defect or inconsistency; 

(b) to provide for the assumption of the Company’s obligations to the Holders of Notes or under the Security

(g) to add covenants that would benefit the Holders or to surrender any rights the Company has under this Indenture, the
Notes, the Security Documents and the Intercreditor Agreement; 
 (h) to add events that constitute Events of
Default with respect to the Notes; 
 (i) to evidence the release of any Guarantor from its Subsidiary Guarantee
or from the Security Documents to which it is a party in accordance with this Indenture; 
 (j) to make,
complete or confirm any grant of Collateral permitted or required by this Indenture or any of the Security Documents; and 
 (k) to make any change that does not adversely affect any outstanding Notes; provided that any change made solely to conform the provisions of this Indenture, the Notes, the Security Documents or the
Intercreditor Agreement to the “Description of the Notes” in the Offering Memorandum will not be deemed to adversely affect any outstanding Notes. 

  
 96 








 Upon the request of the Company, and upon receipt by the Trustee of the documents described
in Section 9.06 hereof, the Trustee and the Collateral Agent shall join with the Company and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any
further appropriate agreements and stipulations that may be therein contained, but neither the Trustee nor the Collateral Agent shall be obligated to enter into such amended or supplemental Indenture that affects its own rights, duties or immunities
under this Indenture or otherwise. 
 Section 9.02 With Consent of Holders of Notes. 

Except as provided above in Section 9.01 and below in this Section 9.02, the Company, the Guarantors, the Trustee
and the Collateral Agent may amend or supplement this Indenture, the Security Documents (by the applicable parties thereto), the Intercreditor Agreement and the Notes with the consent of the Holders of a majority in principal amount of the then
outstanding Notes (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default or compliance with
any provision of this Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes (including consents obtained in connection with a purchase of, tender offer or exchange offer
for Notes). However, without the consent of each Holder of an outstanding Note affected thereby, an amendment, supplement or waiver may not: 
 (a) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; 
 (b) reduce the rate of or change the time for payment of interest, including default interest, on any Note; 
 (c) reduce the principal of, any premium on, or change the stated maturity of, any Note; 
 (d) reduce any premium payable on the redemption or repurchase of any Note or change the time at which any Note may or must be redeemed or repurchased; 

(e) make any Note payable in currency other than as stated in the Notes; 

(f) impair the rights of any Holder to receive payment on or with respect to such Holder’s Notes or to institute
suit for the enforcement of any payment on or with respect to such Holder’s Notes; 
 (g) make any change
in the amendment, supplement or waiver provisions that require the consent of each Holder of an outstanding Note affected thereby; 
 (h) waive a Default or Event of Default in the payment of principal of or premium, interest or Additional Interest, if any, on the Notes (except a rescission of acceleration of the Notes by the Holders of
at least a majority in principal amount of the Notes and a waiver of the payment default that resulted from such acceleration); 

  
 97 








 (i) release any Guarantor of its obligations under a Subsidiary Guarantee,
except in accordance with the terms of this Indenture; 
 (j) make any change to or modify the ranking of the
Notes (or the Liens securing the Notes or the Subsidiary Guarantees) that would adversely affect the Holders of the Notes; 
 (k) make any change in the provisions of the Intercreditor Agreement, the Indenture or the Security Documents dealing with the application of proceeds of Collateral that would adversely affect the Holders
of the Notes; or 
 (l) release all or substantially all of the Collateral from the Lien of the Security
Documents, except in accordance with the terms of this Indenture. 
 Upon the request of the Company accompanied by Board
Resolutions authorizing its execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of
the documents described in Section 9.06 hereof, the Trustee shall join with the Company and the Guarantors in the execution of such amended or supplemental indenture, unless such amended or supplemental indenture affects the
Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture. 

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

After an amendment, supplement or waiver under this Section becomes effective, the Company shall mail to the Holders of Notes 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 amended or supplemental Indenture or waiver.

 Section 9.03 Compliance with Trust Indenture Act. 
 Every amendment or supplement to this Indenture or the Notes shall be set forth in an amended or supplemental Indenture that complies with the TIA as then in effect. 

A consent to any amendment, supplement or waiver under this Indenture by any Holder given in connection with a purchase, tender or
exchange of such Holder’s Notes shall not be rendered invalid by such purchase, tender or exchange. 
 Section 9.04 Revocation and
Effect of Consents. 
 Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is
a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such
Holder of a Note or 

  
 98 








 
subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An
amendment, supplement or waiver becomes effective in accordance with its terms and, except as provided in the second succeeding paragraph, thereafter binds every Holder. 
 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. If a record date is fixed, then
notwithstanding the second to 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 consent to such amendment,
supplement or waiver or revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No consent shall be valid or effective for more than 90 days after such record date except to the extent that the
requisite number of consents to the amendment, supplement or waiver have been obtained within such 90-day period or as set forth in the next paragraph of this Section 9.04. 

After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it makes a change described in any of
clauses (a) through (i) of Section 9.02, in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences
the same indebtedness as the consenting Holder’s Note. 
 Section 9.05 Notation on or Exchange of Notes. 

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company,
in exchange for all Notes, may issue and the Trustee shall authenticate new Notes that reflect the amendment, supplement or waiver. 
 Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver. 
 Section 9.06 Trustee and Collateral Agent to Sign Amendments, etc. 

The Trustee and the Collateral Agent shall sign any amendment or supplement or grant any waiver authorized pursuant to this
Article 9 if the amendment, supplement or waiver does not adversely affect their respective rights, duties, liabilities or immunities. If any such amendment or supplement does adversely affect the rights, duties, liabilities or
immunities of the Trustee and/or the Collateral Agent, the Trustee and/or the Collateral Agent, as the case may be, may, but need not, sign such amended or supplemented Indenture or grant such waiver. In executing any amended or supplemental
indenture, the Trustee and the Collateral Agent shall be entitled to receive and (subject to Section 7.01) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that the execution of
such amended or supplemental indenture is authorized or permitted by this Indenture. 
 Section 9.07 Acts of Holders. 

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to
be given, made or taken by Holders may be 

  
 99 








 
embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing; and, except as herein otherwise
expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose
of this Indenture and (subject to Section 7.01) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. 
 Without limiting the generality of this Section, unless otherwise provided in or pursuant to this Indenture, (i) a Holder, including a Depository or its nominee that is a Holder of a Global Note, may
give, make or take, by an agent or agents duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in or pursuant to this Indenture to be given, made or taken by Holders, and a
Depository or its nominee that is a Holder of a Global Note may duly appoint in writing as its agent or agents members of, or participants in, such Depository holding interests in such Global Note in the records of such Depository; and
(ii) with respect to any Global Note the Depository for which is The Depository Trust Company (“DTC”), any consent or other action given, made or taken by an Agent Member of DTC by electronic means in accordance with the Automated
Tender Offer Procedures system or other customary procedures of, and pursuant to authorization by, DTC shall be deemed to constitute the “Act” of the Holder of such Global Note, and such Act shall be deemed to have been delivered to the
Company and the Trustee upon the delivery by DTC of an “agent’s message” or other notice of such consent or other action having been so given, made or taken in accordance with the Applicable Procedures of DTC. 

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

(c) The ownership of Notes shall be proved by the Register. 

(d) Without limiting the foregoing, a Holder entitled hereunder to give, make or take any action hereunder with regard to
any particular Note may do so, or duly appoint in writing any Person or Persons as its agent or agents to do so, with regard to all or any part of the principal amount of such Note.

 Section 10.01 Subsidiary Guarantees. 

Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally guarantees on a senior basis
to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the Obligations of the Company hereunder and
thereunder, that: 
 (a) the principal of, and interest, premium and Additional Interest, if any, on, the Notes will be promptly
paid in full when due, whether at Stated Maturity, by acceleration, upon repurchase or redemption or otherwise, and interest on the overdue principal of, premium, if any, and (to the extent permitted by law) interest and Additional Interest, if any,
on, the Notes, and all other payment Obligations of the Company to the Holders, the Trustee or the Collateral Agent under this Indenture or the Notes will be promptly paid in full and performed, all in accordance with the terms hereof and thereof;
and 
 (b) in case of any extension of time of payment or renewal of any Notes or any of such other Obligations, the same will
be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, subject to any applicable grace period, whether at Stated Maturity, by acceleration, upon repurchase or redemption or otherwise. 

Failing payment when so due of any amount so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to
pay the same immediately. An Event of Default under this Indenture or the Notes shall constitute an event of default under the Subsidiary Guarantees, and shall entitle the Holders to accelerate the obligations of the Guarantors hereunder in the same
manner and to the same extent as the Obligations of the Company. 
 The Guarantors hereby agree that their obligations hereunder
shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof,
the recovery of any judgment against the Company, any action to enforce the same or any other circumstance (other than complete performance) which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each Guarantor
further, to the extent permitted by law, hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company,
protest, notice and all demands whatsoever and covenants that its Subsidiary Guarantee will not be discharged except by complete performance of the Obligations contained in the Notes and this Indenture. 

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


  
 101








 Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the
Holders and the Trustee, on the other hand, (a) the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of its Subsidiary Guarantee, notwithstanding any stay, injunction
or other prohibition preventing such acceleration in respect of the Obligations guaranteed thereby, and (b) in the event of any declaration of acceleration of such Obligations as provided in Article 6 hereof, such Obligations
(whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purpose of its Subsidiary Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of
such right does not impair the rights of the Holders under the Subsidiary Guarantees. 
 Section 10.02 Guarantors May Consolidate,
etc., on Certain Terms. 
 (a) No Guarantor shall sell or otherwise dispose of, in one or more related
transactions, all or substantially all of its properties or assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person), another Person (other than the Company or another Guarantor), unless:

 (i) immediately after giving effect to such transaction or series of related transactions, no Default or
Event of Default exists; 
 (ii) either (1) such Guarantor is the surviving Person or the Person formed by
or surviving any such consolidation or merger (if other than the Guarantor), or to which such sale or other disposition is made (such Guarantor or such Person, as the case may be, being herein called the “Successor Guarantor”)
unconditionally assumes all the obligations of that Guarantor under the Notes, this Indenture, its Subsidiary Guarantee and any Security Documents to which such Guarantor is a party pursuant to a supplemental indenture substantially in the form of
Annex A hereto or other documents or instruments in form reasonably satisfactory to the Trustee on terms set forth therein, or (2) such transaction or series of related transactions complies with the provisions of Section 4.10;

 (iii) if applicable, the Successor Guarantor causes such amendments, supplements or other instruments to be
executed, delivered , filed and recorded, as applicable, in such jurisdictions as may be required by Applicable Law to preserve and protect the Lien of the Security Documents on any Collateral owned or transferred to such Successor Guarantor;

 (iv) any Collateral owned by or transferred to the Successor Guarantor shall (1) continue to constitute
Collateral under this Indenture and the Security Documents, (2) be subject to a first-priority Lien in favor of the Collateral Agent for the benefit of the Holders of the Notes and (3) not be subject to any Lien other than Liens securing
the Notes or the Second Priority Notes; and 

  
 102








 (v) the property and assets of the Person which is merged or consolidated
with or into any Successor Guarantor, to the extent that they are property or assets of the types which would constitute Collateral under the Security Documents, shall be treated as after-acquired property, and the Successor Guarantor shall take
such action as may be reasonably necessary to cause such property and assets to be made subject to a first-priority Lien in favor of the Collateral Agent for the benefit of the Holders of the Notes. 

(b) In the case of any such consolidation or merger and upon the assumption by the successor Person, by supplemental
indenture, executed and delivered to the Trustee and substantially in the form of Annex A hereto, of the Subsidiary Guarantee of, and the due and punctual performance of all of the covenants of this Indenture to be performed by, the applicable
Guarantor, such successor Person shall succeed to and be substituted for such Guarantor with the same effect as if it had been named herein as a Guarantor. 
 Section 10.03 Releases of Subsidiary Guarantees. 
 The Subsidiary
Guarantee of a Guarantor shall be released: (1) in connection with any sale or other disposition of all or substantially all of the properties or assets of such Guarantor (including by way of merger or consolidation) to a Person that is not
(either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition complies with Section 4.10; (2) in connection with any sale or other disposition of
the Capital Stock of such Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition complies with Section 4.10 and
the Guarantor no longer qualifies as a Subsidiary as a result of such disposition; (3) if such Guarantor is a Restricted Subsidiary and the Company designates such Guarantor as an Unrestricted Subsidiary in accordance with
Section 4.17 of this Indenture; (4) upon Legal Defeasance or Discharge in accordance with Article 8; (5) upon the liquidation or dissolution of such Guarantor, provided no Default or Event of Default has occurred or
is continuing; or (6) (a) if such Guarantor is a Domestic Subsidiary, at such time as such Guarantor ceases both (i) to guarantee any other Indebtedness of the Company or any other Guarantor in excess of the De Minimis Guaranteed
Amount and (ii) to be a Material Domestic Subsidiary; and (b) if such Guarantor is a Foreign Subsidiary, at such time as such Guarantor ceases to guarantee any other Indebtedness of the Company or any other Guarantor in excess of the De
Minimis Guaranteed Amount. 
 Upon delivery by the Company to the Trustee of an Officers’ Certificate to the effect that
any of the conditions described in the foregoing clauses (1) — (6) has occurred, the Trustee shall execute any documents reasonably requested by the Company in order to evidence the release of any Guarantor from its obligations
under its Subsidiary Guarantee. Any Guarantor not released from its obligations under its Subsidiary Guarantee shall remain liable for the full amount of principal of and interest, premium, if any, and Additional Interest, if any, on, the Notes and
for the other obligations of such Guarantor under this Indenture as provided in this Article 10. 

  
 103








 Section 10.04 Limitation on Guarantor Liability. 

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the
Subsidiary Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent
applicable to any Subsidiary Guarantee. The obligations of each Guarantor under its Subsidiary Guarantee will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor and after
giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Subsidiary Guarantee or pursuant to its contribution obligations under this Indenture,
result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law and not otherwise being void or voidable under any similar laws affecting the
rights of creditors generally. 
 Section 10.05 “Trustee” to Include Paying Agent. 

In case at any time any Paying Agent other than the Trustee shall have been appointed and be then acting hereunder, the term
“Trustee” as used in this Article 10 shall in each case (unless the context shall otherwise require) be construed as extending to and including such Paying Agent within its meaning as fully and for all intents and purposes as
if such Paying Agent were named in this Article 10 in place of the Trustee.

upon the expiration of the Escrow Period, the Company and each such Domestic Subsidiary shall, upon the expiration of the Escrow Period, enter into the US Pledge Agreement and such other Security Documents as the Collateral Agent may request in
order to create and perfect security interests in such Specified Collateral Assets (as well as such other assets that constitute Collateral under the US Pledge Agreement) in favor of the Collateral Agent, for the benefit of the Secured Parties,
including Security Documents governed by the law of the jurisdiction of organization of any First-Tier Foreign Subsidiary whose Capital Stock constitutes part of such Specified Collateral Assets or the jurisdiction of organization of the obligor

 104








 The Company shall, and shall cause every other Pledgor to, and each Pledgor shall, make all
filings (including filings of continuation statements and amendments to UCC financing statements that may be necessary to continue the effectiveness of such UCC financing statements) and take all other actions as are reasonably necessary or required
by the Security Documents to maintain (at the sole cost and expense of the Pledgors) the security interest created by the Security Documents in the Collateral as a perfected first-priority security interest. 

(b) Additional Collateral. With respect to any Specified Collateral Assets acquired by the Company or any Domestic Subsidiary at
any time after the expiration of the Escrow Period, the Company or such Domestic Subsidiary, as applicable, will take the actions required by Section 4.20.

to the contrary, upon the execution and delivery of the Intercreditor Agreement (i) the Liens and security interests granted to the Collateral Agent pursuant to the Security Documents and all rights and obligations of the Trustee and Collateral
Agent hereunder shall be expressly subject to the Intercreditor Agreement and (ii) the exercise of any right or remedy by the Trustee and the Collateral Agent hereunder shall be subject to provisions of the Intercreditor Agreement. In the event
of any conflict or inconsistency between the terms of the Intercreditor Agreement and the terms of this Indenture, the terms of the Intercreditor Agreement, when executed and delivered, shall govern.

(1) in whole, upon the full and final payment and performance of all Notes Obligations;

Section 9.02(l); 
 (5) in part, as to any Collateral other than Capital Stock of a First-Tier
Foreign Subsidiary, in connection with any sale or other disposition of such Collateral to a Person that is not (either before or after giving effect to such transaction) the Company or a Subsidiary of the Company in a transaction that is not
prohibited by this Indenture, subject to compliance with Section 4.10; or 
 (6) in part, as to any
property or assets of the Company or any of its Restricted Subsidiaries that become subject to a Lien for the benefit of the Holders of the Notes pursuant to clause (a) of the first paragraph of Section 4.12, at such time as there
are no other Liens of any kind (other than Permitted Liens) on such property or assets securing Indebtedness, as provided in the second paragraph of Section 4.12. 
 Section 11.04 Release Documentation. Upon compliance with the conditions to release of all or any portion of the Collateral set forth in Section 11.03, the Collateral Agent and the
Trustee shall forthwith take all necessary action (at the request of and the expense of the Company, accompanied by an Officers’ Certificate and Opinion of Counsel that the conditions precedent to such release have been satisfied) to release
and re-convey to the applicable Pledgor the applicable portion of the Collateral that is authorized to be released pursuant to Section 11.03, and shall deliver such Collateral in its possession to the applicable Pledgor, including,
without limitation, executing and delivering releases and satisfactions wherever required in form reasonably satisfactory to the Company, the Collateral Agent and the Trustee. 
 Section 11.05 Possession and Use of Collateral. So long as no Event of Default shall have occurred and be continuing, and subject to the terms of the Security Documents, each Pledgor shall be
entitled to exercise any voting and other consensual rights pertaining to the Collateral, including receipt of all payments made on the EEUK Loan, and to subordinate the EEUK Loan on whatever terms the secured creditors of EEUK may require.

 Section 11.06 Reports and Certificates Relating to Collateral. 

(a) To the extent applicable, the Company shall cause Section 313(b) of the TIA, relating to reports, and Section 314(d) of the
TIA, relating to the release of property or securities subject to the Lien of the Security Documents, to be complied with. 

  
 106








 (b) Any certificate or opinion required under Section 314(d) of the TIA may be made by
an officer or legal counsel, as applicable, of the Company except in cases where Section 314(d) of the TIA requires that such certificate or opinion be made by an independent Person, which Person shall be an independent engineer, appraiser or
other expert selected by the Company. 
 (c) Notwithstanding anything to the contrary in this Section 11.06, the
Company shall not be required to comply with all or any portion of Section 314(d) of the TIA if it determines, in good faith based on the advice of counsel, that under the terms of Section 314(d) of the TIA or any interpretation or
guidance as to the meaning thereof of the SEC and its staff, including “no action” letters or exemptive orders, all or any portion of Section 314(d) of the TIA is inapplicable to any release or series of releases of Collateral.

 Section 11.07 Collateral Agent. 
 (a) The Trustee and each of the Holders by acceptance of the Notes hereby acknowledge the Company’s appointment of the Collateral Agent as the Trustee’s and the Holders’ collateral agent
under this Indenture and the Security Documents, and the Trustee and each of the Holders by acceptance of the Notes hereby irrevocably authorize the Collateral Agent to take such action on their behalf under the provisions of this Indenture and the
Security Documents and to exercise such powers and perform such duties as are expressly delegated to the Collateral Agent by the terms of this Indenture and the Security Documents, together with such powers as are reasonably incidental thereto. The
Collateral Agent agrees to act as such on the express conditions contained in this Section 11.07. The provisions of this Section 11.07 are solely for the benefit of the Collateral Agent and none of the Trustee, any of the
Holders, the Company or any of the Domestic Subsidiaries shall have any rights as a third party beneficiary of any of the provisions contained herein. Notwithstanding any provision to the contrary contained elsewhere in this Indenture and the
Security Documents, the Collateral Agent shall not have any duties or responsibilities, except those expressly set forth herein and in the Security Documents, nor shall the Collateral Agent have or be deemed to have any fiduciary relationship with
the Trustee, any Holder or the Company or any Domestic Subsidiary, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Indenture and the Security Documents or otherwise exist against the
Collateral Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” in this Indenture with reference to the Collateral Agent shall not be construed to connote any fiduciary or other implied (or express)
obligations arising under agency doctrine of any Applicable Law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties. Except
as expressly otherwise provided in this Indenture and the Security Documents, the Collateral Agent shall have and may use its sole discretion with respect to exercising or refraining from exercising any discretionary rights or taking or refraining
from taking any actions which the Collateral Agent is expressly entitled to take or assert under this Indenture and the Security Documents, including the exercise of remedies pursuant to Article 6, and any action so taken or not taken shall be
deemed consented to by the Trustee and the Holders. 
 (b) The Collateral Agent may execute any of its duties under this
Indenture and the Security Documents by or through agents, employees or attorneys-in-fact and shall be 

  
 107








 
entitled to advice of counsel concerning all matters pertaining to such duties, and the written advice of such counsel shall be full and complete authorization and protection from liability in
respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. The Collateral Agent shall not be responsible for the negligence or misconduct of any agent, employee or attorney-in-fact that it selects as long
as such selection was made without negligence or willful misconduct. 
 (c) None of the Collateral Agent or any of its agents or
employees shall (i) be liable for any action taken or omitted to be taken by any of them under or in connection with this Indenture or the transactions contemplated hereby (except for its own negligence or willful misconduct) or under or in
connection with any Security Document or the transactions contemplated thereby (except for its own negligence or willful misconduct), or (ii) be responsible in any manner to the Trustee or any Holder for any recital, statement, representation,
warranty, covenant or agreement made by the Company or any Guarantor contained in this Indenture or any of the Security Documents, or in any certificate, report, statement or other document referred to or provided for in, or received by the
Collateral Agent under or in connection with, this Indenture or any of the Security Documents, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Indenture or any of the Security Documents, or for any failure of the
Company or any Guarantor or any other party to this Indenture or any of the Security Documents to perform its obligations hereunder or thereunder. None of the Collateral Agent or any of its agents or employees shall be under any obligation to the
Trustee or any Holder to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Indenture or any of the Security Documents or to inspect the properties, books or records of the
Company or any other Pledgor. 
 (d) The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of
any Default or Event of Default, unless the Collateral Agent shall have received written notice from the Trustee or the Company referring to this Indenture, describing such Default or Event of Default and stating that such notice is a “notice
of default.” The Collateral Agent shall take such action with respect to such Default or Event of Default as may be requested by the Trustee acting in accordance with Article 6 (subject to this Section 11.07); provided, however,
that unless and until the Collateral Agent has received any such request, the Collateral Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall
deem advisable. 
 (e) The Collateral Agent may resign at any time by so notifying the Company and the Trustee in writing at
least thirty (30) days prior to the proposed date of resignation, such resignation to be effective upon the acceptance of a successor agent to its appointment as Collateral Agent. If the Collateral Agent resigns under this Indenture, the
Trustee, subject to the consent of the Company (which shall not be unreasonably withheld and which shall not be required during a continuing Event of Default), shall appoint a successor Collateral Agent. If no successor collateral agent is appointed
prior to the intended effective date of the resignation of the Collateral Agent (as stated in the notice of resignation), the Collateral Agent may appoint, after consulting with the Trustee, subject to the consent of the Company (which shall not be
unreasonably withheld and which shall not be required during a continuing Event of Default), a successor Collateral Agent, which may be the same Person as the Trustee. If no successor Collateral Agent is appointed and consented to by the Company
pursuant to the preceding 

  
 108








 
sentence within thirty (30) days after the intended effective date of resignation (as stated in the notice of resignation) the Collateral Agent, the Company or the Holders of at least 10% in
principal amount of the then outstanding principal amount of the Notes shall be entitled to petition at the expense of the Company a court of competent jurisdiction to appoint a successor Collateral Agent. A successor Collateral Agent shall deliver
a written acceptance of its appointment to the retiring Collateral Agent and to the Company. Thereupon, the resignation of the retiring Collateral Agent shall become effective, and the successor Collateral Agent shall have all the rights, powers and
the duties of the Collateral Agent under this Indenture and the Security Documents. The successor Collateral Agent shall mail a notice of its succession to the Trustee. The retiring Collateral Agent shall promptly transfer all property held by it as
Collateral Agent to the successor Collateral Agent, provided that all sums owing to the retiring Collateral Agent hereunder have been paid. Notwithstanding the replacement of the Collateral Agent pursuant to this Section 11.07(e), the
Company’s obligations under this Section 11.07 and Section 11.12 shall continue for the benefit of the retiring Collateral Agent. 
 (f) Except as otherwise explicitly provided herein or in the Security Documents, neither the Collateral Agent nor any of its officers, directors, employees or agents shall be liable for failure to demand,
collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any other Person or to take any other action whatsoever with regard to the
Collateral or any part thereof. The Collateral Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither the Collateral Agent nor any of its officers, directors, employees or agents
shall be responsible for any act or failure to act hereunder, except for its own willful misconduct, gross negligence or bad faith. 
 (g) The Trustee is authorized and directed by the Holders and the Holders by acquiring the Notes are deemed to have authorized the Trustee, as applicable, upon the expiration of the Escrow Period, to
(i) enter into the Security Documents to which it is a party, (ii) bind the Holders on the terms as set forth in such Security Documents, (iii) perform and observe its obligations under such Security Documents and (iv) cause the
Collateral Agent to enter into and perform its obligations under the Security Documents. The Collateral Agent is authorized and directed by the Trustee and the Holders and the Holders by acquiring the Notes are deemed to have authorized the
Collateral Agent, upon the expiration of the Escrow Period, to (i) enter into the Security Documents to which it is a party, (ii) bind the Trustee and the Holders on the terms as set forth in such Security Documents and (iii) perform
and observe its obligations under such Security Documents. 
 (h) The Collateral Agent shall have no obligation whatsoever to
the Trustee or any of the Holders to assure that the Collateral exists or is owned by the Company and the other Pledgors or is cared for, protected or insured or has been encumbered, or that the Collateral Agent’s Liens have been properly or
sufficiently or lawfully created, perfected, protected, maintained or enforced or are entitled to any particular priority, or to determine whether all of the Grantor’s property constituting Collateral intended to be subject to the Lien and
security interest of the Security Documents has been properly and completely listed or delivered, as the case may be, or the genuineness, validity, marketability or sufficiency thereof or title thereto. 

  
 109








 (i) The Collateral Agent (i) shall not be liable for any action it takes or omits to
take in good faith that it believes to be authorized or within its rights or powers, or for any error of judgment made in good faith by an authorized officer, unless it is proved that the Collateral Agent was negligent in ascertaining the pertinent
facts, (ii) shall not be liable for interest on any money received by it except as the Collateral Agent may agree in writing with the Company (and money held in trust by the Collateral Agent need not be segregated from other funds except to the
extent required by law), and (iii) may consult with counsel of its selection and the written advice or opinion of such counsel shall be full and complete authorization and protection from liability in respect of any action taken, suffered or
omitted by it hereunder in good faith and in reliance thereon. The grant of permissive rights or powers to the Collateral Agent shall not be construed to impose duties to act. 
 (j) It is hereby understood that the Dutch Parallel Debt (as defined in the Dutch Pledge Agreement) has been included in the Dutch Pledge Agreement for the purpose of determining the secured obligations
in any Collateral that is governed by Dutch law, and in relation to such Dutch Parallel Debt: 
  

	 	(i)	the Collateral Agent shall act in its own name and not as agent of any Secured Party (but always for the benefit of the Secured Parties in accordance with the
provisions of this Indenture, the Notes, the Intercreditor Agreement and the Security Documents); 

  

	 	(ii)	the rights, powers and authorities vested in the Collateral Agent pursuant to this Indenture, the Notes, the Intercreditor Agreement, the Security Documents, the
Subsidiary Guarantees and any other agreements or instruments required to be executed pursuant to the terms thereof are subject to any restrictions imposed by mandatory Dutch law; and 


 

	 	(iii)	the Collateral Agent shall be entitled to accept the Dutch Parallel Debt on behalf of each of the Secured Parties, notwithstanding the foregoing.


 (k) If the Collateral Agent resigns in accordance with this Section 11.07, EOC shall execute such
documents and take such other action as is necessary or (in the opinion of the Collateral Agent) desirable in connection with the substitution, in accordance with Applicable Law, of the successor Collateral Agent as creditor of the Dutch Parallel
Debt and as beneficiary of the Dutch Pledge Agreement securing the Dutch Parallel Debt. 
 Section 11.08 Purchaser
Protected. No purchaser or grantee of any property or rights purporting to be released from the Liens in favor of the Collateral Agent shall be bound to ascertain the authority of the Collateral Agent or Trustee to execute the release or to
inquire as to the existence of any conditions herein prescribed for the exercise of such authority so long as the conditions set forth in Section 11.03 have been satisfied. 

Section 11.09 Authorization of Actions to Be Taken by the Collateral Agent Under the Security Documents. Subject to the provisions
of the Security Documents, (a) each of the Trustee and the Collateral Agent may, in its sole discretion and without the consent of the Holders, take all actions as it deems necessary or appropriate in order to (i) enforce any of the


  
 110








 
terms of the Security Documents and (ii) collect and receive any and all amounts payable in respect of the Notes Obligations and (b) each of the Trustee and the Collateral Agent shall
have power to institute and to maintain such suits and proceedings as it may deem expedient to prevent any impairment of the Collateral by any act that may be unlawful or in violation of the Security Documents or this Indenture, and such suits and
proceedings as the Trustee or the Collateral Agent may deem expedient to preserve or protect its interests and the interests of the Holders in the 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). 
 Section 11.10
Authorization of Receipt of Funds by the Trustee Under the Security Documents. The Trustee is authorized to receive any funds for the benefit of Holders distributed under the Security Documents and to apply such funds as provided in
Section 6.10. 
 Section 11.11 Powers Exercisable by Receiver or Trustee. In case the Collateral shall be in
the possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article 11 upon the Company or any Guarantor, as applicable, with respect to the release, sale or other disposition of such property may be exercised by such
receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of the Company or any Guarantor, as applicable, or of any officer or officers thereof required by the provisions of
this Article 11. 
 Section 11.12 Compensation and Indemnification. The Collateral Agent shall be entitled to the
compensation and indemnification set forth in Section 7.07 (with the references to the Trustee therein being deemed to refer to the Collateral Agent).

 App. - 2








 
Depository, duly executed by the Company and authenticated by the Trustee as hereinafter provided. Beneficial interests in a Restricted Global Note representing Initial Notes sold in reliance on
either Rule 144A or Regulation S may be held through Euroclear or Clearstream, as indirect participants in the Depository. The aggregate principal amount of the Global Notes may from time to time be increased or decreased by adjustments made on the
records of the Trustee and the Depository or its nominee as hereinafter provided. Exchange Notes shall be issued in global form (with the global Notes legend set forth in Exhibit 1 hereto) or in certificated form as provided in Section 2.4 of
this Appendix. Exchange Notes issued in global form, Unrestricted Initial Notes issued in global form and Restricted Global Notes are sometimes referred to in this Appendix as “Global Notes.” 

(b) Book-Entry Provisions. This Section 2.1(b) shall apply only to a Global Note deposited with or on behalf of the
Depository. 
 The Company shall execute and the Trustee shall, in accordance with this Section 2.1(b), authenticate and
deliver initially one or more Global Notes that (a) shall be registered in the name of the Depository for such Global Note or Global Notes or the nominee of such Depository and (b) shall be delivered by the Trustee to such Depository or
pursuant to such Depository’s instructions or held by the Trustee as custodian for the Depository. If such Global Notes are Restricted Global Notes, then separate Global Notes shall be issued to represent Rule 144A Notes and Regulation S Notes
so long as required by law or the Depository. 
 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 by the Trustee as the custodian of the Depository or under such Global Note, and the Company, the Trustee and any agent of the
Company or the Trustee shall be entitled to treat the Depository as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company
or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its Agent Members, the operation of customary practices of such Depository governing
the exercise of the rights of a holder of a beneficial interest in any Global Note. 
 Prior to the expiration of the period
through and including the 40th day after the later of the commencement of the offering of any Initial Notes and the closing of such offering (such period, the “Restricted Period”), beneficial interests in the Restricted Global Note

meaning of Rule 144A and is purchasing for its own account or the account of a QIB, in each case in a transaction meeting the requirements of Rule 144A, and (iii) the transfer is in accordance with all applicable securities laws of the states
of the United States and other jurisdictions. After the expiration of the Restricted Period, such certification requirements shall not apply to such transfers of beneficial interests in a Restricted Global Note representing Regulation S Notes.


  
 App. - 3








 Beneficial interests in a Restricted Global Note representing Rule 144A Notes may be
transferred to a Person who takes delivery in the form of an interest in the Restricted Global Note representing Regulation S Notes, whether before or after the expiration of the Restricted Period, only if the transferor first delivers to the
Trustee a written certificate (in the form provided in Exhibit 1 hereto) to the effect that such transfer is being made in accordance with Rule 903 or 904 of Regulation S or Rule 144 (if available) and that, if such transfer occurs prior to the
expiration of the Restricted Period, the interest transferred will be held immediately thereafter through Euroclear of Clearstream. 
 (c) Certificated Notes. Except as provided in Section 2.3 or 2.4, owners of beneficial interests in Restricted Global Notes shall not be entitled to receive physical delivery of certificated
Notes. Certificated Notes shall not be exchangeable for beneficial interests in Global Notes. 
 2.2 Authentication. The
Trustee shall authenticate and deliver: (1) on the Initial Issuance Date, an aggregate principal amount of $350,000,000 12% First Priority Notes due 2018, (2) at any time or from time to time, any Additional Notes for an original issue in

Registration Rights Agreement, for a like principal amount of Initial Notes, in each case upon a written order of the Company. Such order (x) shall specify (i) the aggregate principal amount of the Notes to be authenticated, the date on
which such Notes are to be authenticated and to whom such Notes shall be registered and delivered; (ii) whether such Notes constitute Initial Notes or Exchange Notes; (iii) whether or not such Notes constitute Additional Notes; and
(iv) if such Notes constitute Additional Notes, the issue price, the issue date (and the corresponding date from which interest shall accrue thereon and the first interest payment date therefor) and the CUSIP number and any corresponding ISIN
of such Additional Notes and whether such Additional Notes shall be Transfer Restricted Securities and issued in the form of Initial Notes as set forth in Exhibit 1 hereto or shall be issued in the form of Exchange Notes as set forth in Exhibit 2
hereto and (y) in the case of any issuance of Additional Notes pursuant to Section 2.13 of the Indenture, shall certify that such issuance is in compliance with Section 4.09 of the Indenture. The Trustee shall also authenticate and
deliver Notes at the times and in the manner specified in Sections 2.3 and 2.4 hereof and in Sections 2.06, 2.07, 2.09, 3.06, 4.10, 4.15 or 9.05 of the Indenture. 
 2.3 Transfer and Exchange. 
 (a) Transfer and Exchange of Global
Notes. (i) The transfer and exchange of Global Notes or beneficial interests therein shall be effected through the Depository, in accordance with the Indenture (including applicable restrictions on transfer set forth herein, if any) and the
procedures of the Depository therefor. A transferor of a beneficial interest in a Rule 144A Global Note to a Regulation S Global Note or a Regulation S Global Note to a Rule 144A Global Note shall deliver to the Registrar a written order given in
accordance with the Depository’s procedures containing information regarding the participant account of the Depository to be credited with a beneficial interest in the Global Note. The Registrar shall, in accordance with such instructions
instruct the Depository to credit to the account of the Person specified in such instructions a beneficial interest in the Global Note and to debit the account of the Person making the transfer the beneficial interest in the Global Note being
transferred. 

  
 App. - 4








 (ii) Notwithstanding any other provisions of this Appendix, a Global Note
may not be transferred as a whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or
a nominee of such successor Depository. 
 (iii) In the event that a Restricted Global Note is exchanged for
Notes in certificated form pursuant to Section 2.4 of this Appendix, prior to the consummation of a Registered Exchange Offer or the effectiveness of a Shelf Registration Statement with respect to such Notes, such Notes may be exchanged only in
accordance with such procedures as are substantially consistent with the provisions of this Section 2.3 (including the certification requirements set forth on the reverse of the Initial Notes intended to ensure that such transfers comply with
Rule 144A or Regulation S, as the case may be) and such other procedures as may from time to time be adopted by the Company. 

(b) Legend. 
 (i) Except as permitted by the following paragraphs (ii), (iii), (iv) and (v), each Note certificate evidencing the Restricted Global Notes (and all Notes issued in exchange therefor or in
substitution thereof) shall bear a legend in substantially the following form: 
 THIS NOTE HAS NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS. NEITHER THIS NOTE NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF
IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. THE HOLDER OF THIS NOTE BY ITS ACCEPTANCE HEREOF (1) REPRESENTS THAT (A) IT IS A
“QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS NOT A U.S. PERSON AND IS ACQUIRING SUCH NOTE IN AN “OFFSHORE TRANSACTION” WITHIN THE MEANING OF REGULATION S UNDER THE
SECURITIES ACT, (2) AGREES TO OFFER, SELL OR OTHERWISE TRANSFER SUCH NOTE, PRIOR TO THE DATE (THE “RESALE RESTRICTION TERMINATION DATE”) WHICH IS ONE YEAR AFTER THE LATER OF THE ORIGINAL ISSUE DATE HEREOF AND THE LAST DATE ON WHICH
THE COMPANY OR ANY AFFILIATE OF THE COMPANY WAS THE OWNER OF SUCH NOTE (OR ANY PREDECESSOR OF SUCH NOTE) OR ONLY (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) FOR SO LONG AS THIS NOTE IS ELIGIBLE FOR RESALE PURSUANT TO RULE 144A, TO A
PERSON IT REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR 

  
 App. - 5








 
THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHICH NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (C) PURSUANT TO OFFERS AND SALES TO NON-U.S. PURCHASERS THAT
OCCUR OUTSIDE THE UNITED STATES WITHIN THE MEANING OF REGULATION S UNDER THE SECURITIES ACT, (D) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT OR (E) PURSUANT TO ANOTHER AVAILABLE EXEMPTION
FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE COMPANY’S AND THE TRUSTEE’S RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO CLAUSE (B), (C) OR (E) TO REQUIRE THE DELIVERY OF AN OPINION OF
COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM, AND IN EACH OF THE FOREGOING CASES, A CERTIFICATE OF TRANSFER IN THE FORM APPEARING IN THE INDENTURE IS COMPLETED AND DELIVERED BY THE TRANSFEROR TO THE TRUSTEE. THIS
LEGEND WILL BE REMOVED UPON THE REQUEST OF THE HOLDER AFTER THE RESALE RESTRICTION TERMINATION DATE. 
 (ii) The
Company, acting in its discretion, may remove the legend set forth in paragraph (i) above from any Transfer Restricted Security at any time on or after the Resale Restriction Termination Date applicable to such Transfer Restricted Security.
Without limiting the generality of the preceding sentence, the Company may effect such removal by issuing and delivering, in exchange for such Transfer Restricted Security, an Unrestricted Initial Note without such legend, registered to the same
Holder and in an equal principal amount, and upon receipt by the Trustee of a written order of the Company stating that the Resale Restriction Termination Date applicable to such Transfer Restricted Security has occurred and requesting the
authentication and delivery of an Unrestricted Initial Note in exchange therefor (which order shall not be required to be accompanied by any Opinion of Counsel or any other document) given at least three Business Days in advance of the proposed date
of exchange specified therein (which shall be no earlier than such Resale Restriction Termination Date), the Trustee shall authenticate and deliver such Unrestricted Initial Note to the Depository or pursuant to such Depository’s instructions
or hold such Note as Note Custodian for the Depository and shall request the Depository to, or, if the Trustee is Note Custodian of such Transfer Restricted Security, shall itself, surrender such Transfer Restricted Security in exchange for such
Unrestricted Initial Note without such legend and thereupon cancel such Transfer Restricted Security so surrendered, all as directed in such order. For purposes of determining whether the Resale Restriction Termination Date has occurred with respect
to any Notes evidenced by a Transfer Restricted Security or delivering any order pursuant to this Section 2.3(b)(ii) with respect to such Notes, (i) only those Notes which a Principal Officer of the Company actually knows (after reasonable
inquiry) to be or to have been owned by an Affiliate of the Company shall be deemed to be or to have been, respectively, owned by an Affiliate of the Company; and (ii) “Principal Officer” means the principal executive officer, the
principal financial officer, the treasurer or the principal accounting officer of the Company. 

  
 App. -6








 For purposes of this Section 2.3(b)(ii), all provisions relating to the removal of the
legend set forth in paragraph (i) above shall relate, if the Resale Restriction Termination Date has occurred only with respect to a portion of the Notes evidenced by a Transfer Restricted Security, to such portion of the Notes so evidenced as
to which the Resale Restriction Termination Date has occurred. 
 Each holder of any Note evidenced by any Restricted Global
Note, by its acceptance thereof, (A) authorizes and consents to, (B) appoints the Company as its agent for the sole purpose of delivering such electronic messages, executing and delivering such instruments and taking such other actions, on
such holder’s behalf, as the Depository or the Trustee may require to effect, and (C) upon the request of the Company, agrees to deliver such electronic messages, execute and deliver such instruments and take such other actions as the
Depository or the Trustee may require, or as shall otherwise be necessary to effect, the removal of the legend set forth in Section 2.3(b)(i) (including by means of the exchange of all or the portion of such Restricted Global Note evidencing
such Note for a certificate evidencing such Note that does not bear such legend) at any time after the Resale Restriction Termination Date. 
 (iii) Upon any sale or transfer of a Transfer Restricted Security (including any Transfer Restricted Security represented by a Restricted Global Note) pursuant to Rule 144 under the Securities Act, the
Registrar shall permit the transferee thereof to exchange such Transfer Restricted Security for a certificated Note that does not bear the legend set forth above and rescind any restriction on the transfer of such Transfer Restricted Security, if
the transferor thereof certifies in writing to the Registrar that such sale or transfer was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse of the Note). 

(iv) After a transfer of any Initial Notes pursuant to and during the period of the effectiveness of a Shelf Registration
Statement with respect to such Initial Notes, all requirements pertaining to legends on such Initial Note will cease to apply, the requirement that any such Initial Note issued to certain Holders be issued in global form will cease to apply, and a
certificated Initial Note or an Initial Note in global form, in each case without restrictive transfer legends, will be available to the transferee of the Holder of such Initial Notes upon exchange of such transferring Holder’s certificated
Initial Note or directions to transfer such Holder’s interest in the Global Note, as applicable. 
 (v)
Upon the consummation of a Registered Exchange Offer with respect to the Initial Notes, all requirements pertaining to such Initial Notes that Initial Notes issued to certain Holders be issued in global form will still apply with respect to Holders
of such Initial Notes that do not exchange their Initial Notes, and Exchange Notes in certificated or global form will be available to Holders that exchange such Initial Notes in such Registered Exchange Offer. 

(c) Cancellation or Adjustment of Global Note. At such time as all beneficial interests in a Global Note have either been
exchanged for certificated Notes, redeemed, purchased or canceled, such Global Note shall be returned to the Trustee for cancellation or 

  
 App. - 7








 
retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for certificated Notes, redeemed, purchased or canceled, or
if any certificated Note is exchanged for such a beneficial interest, the principal amount of Notes represented by such Global Note shall be reduced or increased, as appropriate, and an adjustment shall be made on the books and records of the
Trustee (if it is then the Notes Custodian for such Global Note) with respect to such Global Note, by the Trustee or the Notes Custodian, to reflect such reduction or increase, as the case may be. 

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

(i) To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate
certificated Notes and Global Notes at the Registrar’s request. 
 (ii) No service charge shall be made for
any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax, assessments or similar governmental charge payable in connection therewith (other than any such transfer taxes, assessments
or similar governmental charge payable upon any exchange or transfer pursuant to Sections 3.06, 4.10, 4.15 and 9.05 of the Indenture). 
 (iii) The Registrar shall not be required to register the transfer of or exchange of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in
part. Also, it need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed. 
 (iv) Prior to the due presentation for registration of transfer of any Note, the Company, the Guarantors, the Trustee, the Paying Agent or the Registrar may deem and treat the Person in whose name a Note
is registered as the absolute owner of such Note for the purpose of receiving payment of principal of, interest, premium, if any, and Additional Interest, if any, on, such Note and for all other purposes whatsoever, whether or not such Note is
overdue, and none of the Company, the Guarantors, the Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary. 
 (v) All Notes issued upon any transfer or exchange pursuant to the terms of this Indenture shall evidence the same debt and shall be entitled to the same benefits under this Indenture as the Notes
surrendered upon such transfer or exchange. Accordingly, for purposes of clause (3) of the second paragraph of Section 4.09 of this Indenture, “the Notes issued and sold on the Initial Issuance Date” shall be deemed to refer to
and include any Notes issued in exchange for, or upon registration of transfer of, or in lieu of, any such Notes (or any predecessor Notes thereof) pursuant to Sections 2.3 or 2.4 hereof or Sections 2.06, 2.07, 2.09, 3.06, 4.10, 4.15 or 9.05 of this

 [FORM OF REVERSE SIDE OF INITIAL NOTE] 

12% First Priority Note due 2018 
 Capitalized terms used herein but not defined shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 

1. Interest. Endeavour International Corporation, a Nevada corporation (the “Company”), promises to pay interest on the
principal amount of this Note at 12% per annum from February 23, 2012 until maturity and shall pay Additional Interest payable pursuant to Section 5 of the Registration Rights Agreement referred to below. The Company will pay interest
and Additional Interest, if any, semi-annually in arrears on March 1 and September 1 of each year (each an “Interest Payment Date”), commencing September 1, 2012. If any date for payment of interest, principal or premium on
the Notes falls on a day that is not a Business Day, such payment may be made on the next succeeding Business Day with the same force and effect as if made on the due date, and no additional interest will accrue solely as a result of such delayed
payment. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of original issuance; provided that if there is no existing Default or Event of Default in the
payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date, except in the case of
the original issuance of Notes, in which case interest shall accrue from the date of authentication. The Company shall pay (i) interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and
premium, if any, from time to time on demand at a rate that is 1% higher than the then applicable interest rate on the Notes and (ii) interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments
of interest and Additional Interest (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 

2. Method of Payment. The Company will pay interest on the Notes (except defaulted interest) and Additional Interest to the
Persons who are registered Holders of Notes at the close of business on the February 15 or August 15 next preceding the Interest Payment Date, even if such Notes are cancelled after such record date and on or before such Interest Payment
Date, except as provided in Section 2.11 of the Indenture with respect to defaulted interest. Holders must surrender Notes to the Paying Agent to collect payments of principal and premium, if any, together with accrued and unpaid interest and
Additional Interest, if any, due at maturity. Any Notes in certificated form will be payable as to principal, interest, premium, if any, and Additional Interest, if any, at the office or agency of the Company maintained for such purpose within the
City and State of New York, or, at the option of the Company, payment of interest and Additional Interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders, and provided that payment by wire transfer
of immediately available funds to an account in the United States will be required with respect to any amounts due on all Global Notes and all other Notes the Holders of which shall have provided wire transfer instructions to the Company or the
Paying Agent. Notwithstanding the foregoing, if this Note is a Global Note, payment may be made pursuant to the Applicable Procedures of the Depository as permitted in the Indenture. Such payment shall be in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of public and private debts. 

  
 Exhibit 1 to
App. - 5 







 3. Paying Agent and Registrar. Initially, Wells Fargo Bank, National Association, the
Trustee under the Indenture, will act as Paying Agent and Registrar at its corporate trust office at 45 Broadway, 14th Floor, New York, New York 10006. The Company may appoint and change any Paying Agent or Registrar without notice to any Holder.
The Company or any of its Subsidiaries may act in any such capacity. 
 4. Indenture. The Company issued the Notes under
an Indenture dated as of February 23, 2012 (“Indenture”) among the Company, the Guarantors, the Trustee and the Collateral Agent. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. The Notes are senior
obligations of the Company, and the aggregate principal amount of the Notes is unlimited. 
 5. Optional Redemption.

 (a) Except as set forth in subparagraphs (b), (c) and (d) of this Paragraph 5, the Company shall not have the
option to redeem the Notes prior to March 1, 2015. On or after March 1, 2015, the Company shall have the option to redeem the Notes, in whole or in part at any time, upon prior notice as set forth in Paragraph 6, at the redemption prices
(expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest and Additional Interest, if any, on the Notes redeemed to the applicable redemption date (subject to the right of Holders of record on the relevant
record date to receive interest due on an Interest Payment Date that is on or prior to the redemption date), if redeemed during the twelve-month period beginning on March 1 of the years indicated below: 

 

					
	 YEAR
	  	PERCENTAGE	 
	 2015
	  	 	106.0	% 
	 2016
	  	 	103.0	% 
	 2017 and thereafter
	  	 	100.0	% 

 (b) Notwithstanding the provisions of subparagraph (a) of this Paragraph 5, at any time prior to
March 1, 2015, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of Notes issued under the Indenture at a redemption price of 112.00% of the principal amount thereof, plus accrued and unpaid
interest and Additional Interest, if any, thereon to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the redemption date), with the
net cash proceeds of one or more Equity Offerings; provided that, with respect to each such redemption, (i) at least 65% of the aggregate principal amount of Notes issued under the Indenture remains outstanding immediately after the occurrence
of such redemption (excluding any Notes held by the Company and its Subsidiaries) and (ii) such redemption occurs within 180 days of the date of the closing of the related Equity Offering. 

  
 Exhibit 1 to
App. - 6 







 (c) Prior to March 1, 2015, the Company may redeem on any one or more occasions all or
part of the Notes at a redemption price equal to the sum of (1) 100% of the principal amount thereof, plus (2) accrued and unpaid interest, if any, to the redemption date (subject to the right of Holders of record on the relevant record
date to receive interest due on an interest payment date that is on or prior to the redemption date), plus (3) the Make Whole Premium at the redemption date. 
 (d) The Notes may also be redeemed, as a whole, following certain Change of Control Offers, at the redemption price and subject to the conditions set forth in the last paragraph of Section 4.15 of
the Indenture. 
 6. Notice of Redemption. Notice of redemption will be mailed at least 30 days but not more than 60 days
(except as otherwise provided in the Indenture if the notice is issued in connection with a Legal Defeasance, Covenant Defeasance or Discharge) before the redemption date to each Holder whose Notes are to be redeemed at its registered address. If
mailed in the manner provided for in Section 3.03 of the Indenture, the notice of optional redemption shall be conclusively presumed to have been given whether or not a Holder receives such notice. Failure to give timely notice or any defect in
the notice shall not affect the validity of the redemption. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000 in excess of $2,000, unless all of the Notes held by a Holder are to be redeemed. On
and after the redemption date, interest and Additional Interest, if any, cease to accrue on the Notes or portions thereof called for redemption. The notice of redemption with respect to a redemption described in Paragraph 5(c) above need not set
forth the Make Whole Premium but only the manner of calculation thereof. 
 7. Mandatory Redemption. 

Except as set forth in this Paragraph 7 and in Paragraph 8 below, the Company shall not be required to make mandatory redemption or
sinking fund payments with respect to the Notes or to repurchase the Notes at the option of the Holders. 
 Following the
Special Mandatory Redemption Trigger Event, the Initial Notes are subject to mandatory redemption as a whole, upon the giving of prior notice to Holders and on the redemption date and for the redemption price set forth in Section 3.08 of the
Indenture. 
 8. Repurchase at Option of Holder. 

(a) Within 30 days following the occurrence of a Change of Control, unless the Company has given a notice of redemption of all
outstanding Notes, the Company shall make an offer (a “Change of Control Offer”) to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess of $2,000) of each Holder’s Notes at a purchase price in cash
equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest and Additional Interest, if any, to the date of purchase (the “Change of Control Purchase Date”), subject to the right of Holders of
record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Change of Control Purchase Date. Within 30 days following a Change of Control, unless the Company has given a notice of redemption of
all outstanding Notes, the Company shall mail a notice of the Change of Control Offer to each 

  
 Exhibit 1 to
App. - 7 







 
Holder and the Trustee describing the transaction or transactions that constitutes the Change of Control and setting forth the procedures governing the Change of Control Offer as required by
Section 4.15 of the Indenture. 
 (b) When the aggregate amount of Collateral Net Proceeds exceeds $10 million, the Company
shall, within 60 days following the date on which such Collateral Net Proceeds first exceed such amount, use all Collateral Net Proceeds to make a Collateral Sale Offer to all Holders of Notes to purchase, on a pro rata basis, the maximum principal
amount of Notes that may be purchased out of the Collateral Net Proceeds. After completion of the Collateral Sale Offer, if there are any remaining Collateral Net Proceeds in excess of $10 million, the Company shall, within 60 days following the
consummation of such Collateral Sale Offer, use all remaining Collateral Net Proceeds to make a Second Priority Collateral Sale Offer to all holders of Second Priority Notes, to purchase, on a pro rata basis, the maximum principal amount of Second
Priority Notes that may be purchased out of such remaining Collateral Net Proceeds. The Company or any Restricted Subsidiary of the Company may invest the remaining Net Proceeds in any manner that is not prohibited by the Indenture. The offer price
in any Collateral Sale Offer or Second Priority Collateral Sale Offer will be equal to 100% of principal amount plus accrued and unpaid interest, if any, and Additional Interest, if any, thereon to the Settlement Date, subject to the right of
Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the Settlement Date, and will be payable in cash. 
 (c) On the 366th day after an Asset Sale other than a Collateral Disposition (or, at the Company’s option, any earlier date), if the aggregate amount of Excess Proceeds then exceeds $10 million, the
Company shall commence an offer to all Holders of Notes (an “Asset Sale Offer”) pursuant to Section 3.09 of the Indenture, and, subject to limitations contained in Section 4.07 of the Indenture, to all holders of Second Priority
Notes, as well as to all holders of any Pari Passu Indebtedness then outstanding, to purchase, on a pro rata basis, the maximum principal amount of Notes, Second Priority Notes and such Pari Passu Indebtedness that may be purchased out of the Excess
Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount of the Notes plus accrued and unpaid interest and Additional Interest, if any, thereon to the date of settlement, subject to the right of Holders of record on the
relevant record date to receive interest due on an Interest Payment Date that is on or prior to the date of settlement, in accordance with the procedures set forth in the Indenture. If any Excess Proceeds remain after consummation of an Asset Sale
Offer, the Company may use such remaining Excess Proceeds for any purpose not otherwise prohibited by the Indenture. 
 (d) If
the aggregate principal amount of Notes tendered into a Collateral Sale Offer or Asset Sale Offer exceeds the amount of proceeds allocated for the purchase of Notes, the Trustee will select the Notes to be purchased on a pro rata basis (with such
adjustments as may be deemed appropriate by the Trustee so that only Notes in denominations of $2,000, or integral multiples of $1,000 in excess of $2,000, shall be purchased) or, in the case of Global Notes, the Trustee will select Notes for
purchase based on DTC’s method that most nearly approximates a pro rata selection unless otherwise required by law. Holders of Notes that are the subject of an offer to purchase will receive a Collateral Sale Offer or an Asset Sale Offer from
the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” on the reverse of the Notes.

 Exhibit 1 to
App. - 10 







 
behalf of the Holders of all the Notes rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except
with respect to nonpayment of principal, interest, premium, or Additional Interest, if any, that have become due solely because of the acceleration) have been cured or waived. The Holders of a majority in principal amount of the Notes then
outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive (including, without limitation, in connection with a purchase of, or tender offer or exchange offer for, the Notes) any existing Default or Event of Default
and its consequences under the Indenture except a continuing Default or Event of Default in the payment of the principal of, or interest, premium, if any, or Additional Interest, if any, on, the Notes or in respect of a covenant that cannot be
amended without the consent of each Holder. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and, so long as any Notes are outstanding, upon any officer of the Company becoming aware of
any Default or Event of Default, the Company shall deliver to the Trustee a statement specifying such Default or Event of Default.

 [FORM OF REVERSE SIDE OF EXCHANGE NOTE] 

12% First Priority Note due 2018 
 Capitalized terms used herein but not defined shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 

1. Interest. Endeavour International Corporation, a Nevada corporation (the “Company”), promises to pay interest on the
principal amount of this Note at 12% per annum from February 23, 2012 until maturity and shall pay Additional Interest payable pursuant to Section 5 of the Registration Rights Agreement referred to below. The Company will pay interest
and Additional Interest, if any, semi-annually in arrears on March 1 and September 1 of each year (each an “Interest Payment Date”), commencing September 1, 2012. If any date for payment of interest, principal or premium on
the Notes falls on a day that is not a Business Day, such payment may be made on the next succeeding Business Day with the same force and effect as if made on the due date, and no additional interest will accrue solely as a result of such delayed
payment. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of original issuance; provided that if there is no existing Default or Event of Default in the
payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date, except in the case of
the original issuance of Notes, in which case interest shall accrue from the date of authentication. The Company shall pay (i) interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and
premium, if any, from time to time on demand at a rate that is 1% higher than the then applicable interest rate on the Notes and (ii) interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments
of interest and Additional Interest (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 

2. Method of Payment. The Company will pay interest on the Notes (except defaulted interest) and Additional Interest to the
Persons who are registered Holders of Notes at the close of business on the February 15 or August 15 next preceding the Interest Payment Date, even if such Notes are cancelled after such record date and on or before such Interest Payment
Date, except as provided in Section 2.11 of the Indenture with respect to defaulted interest. Holders must surrender Notes to the Paying Agent to collect payments of principal and premium, if any, together with accrued and unpaid interest and
Additional Interest, if any, due at maturity. Any Notes in certificated form will be payable as to principal, interest, premium, if any, and Additional Interest, if any, at the office or agency of the Company maintained for such purpose within the
City and State of New York, or, at the option of the Company, payment of interest and Additional Interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders, and provided that payment by wire transfer
of immediately available funds to an account in the United States will be required with respect to any amounts due on all Global Notes and all other Notes the Holders of which shall have provided wire transfer instructions to the Company or the
Paying Agent. Notwithstanding the foregoing, if this Note is a Global Note, payment may be made pursuant to the Applicable Procedures of the Depository as permitted in the Indenture. Such payment shall be in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of public and private debts. 

  
 Exhibit 2 to
App. - 3 







 3. Paying Agent and Registrar. Initially, Wells Fargo Bank, National Association, the
Trustee under the Indenture, will act as Paying Agent and Registrar at its corporate trust office at 45 Broadway, 14th Floor, New York, New York 10006. The Company may appoint and change any Paying Agent or Registrar without notice to any Holder.
The Company or any of its Subsidiaries may act in any such capacity. 
 4. Indenture. The Company issued the Notes under
an Indenture dated as of February 23, 2012 (“Indenture”) among the Company, the Guarantors, the Trustee and the Collateral Agent. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. The Notes are senior
obligations of the Company, and the aggregate principal amount of the Notes is unlimited. 
 5. Optional Redemption.

 (a) Except as set forth in subparagraphs (b), (c) and (d) of this Paragraph 5, the Company shall not have the
option to redeem the Notes prior to March 1, 2015. On or after March 1, 2015, the Company shall have the option to redeem the Notes, in whole or in part at any time, upon prior notice as set forth in Paragraph 6, at the redemption prices
(expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest and Additional Interest, if any, on the Notes redeemed to the applicable redemption date (subject to the right of Holders of record on the relevant
record date to receive interest due on an Interest Payment Date that is on or prior to the redemption date), if redeemed during the twelve-month period beginning on March 1 of the years indicated below: 

 

					
	 YEAR
	  	PERCENTAGE	 
	 2015
	  	 	106.0	% 
	 2016
	  	 	103.0	% 
	 2017 and thereafter
	  	 	100.0	% 

 (b) Notwithstanding the provisions of subparagraph (a) of this Paragraph 5, at any time prior to
March 1, 2015, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of Notes issued under the Indenture at a redemption price of 112.00% of the principal amount thereof, plus accrued and unpaid
interest and Additional Interest, if any, thereon to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the redemption date), with the
net cash proceeds of one or more Equity Offerings; provided that, with respect to each such redemption, (i) at least 65% of the aggregate principal amount of Notes issued under the Indenture remains outstanding immediately after the occurrence
of such redemption (excluding any Notes held by the Company and its Subsidiaries) and (ii) such redemption occurs within 180 days of the date of the closing of the related Equity Offering. 

  
 Exhibit 2 to
App. - 4 







 (c) Prior to March 1, 2015, the Company may redeem on any one or more occasions all or
part of the Notes at a redemption price equal to the sum of (1) 100% of the principal amount thereof, plus (2) accrued and unpaid interest, if any, to the redemption date (subject to the right of Holders of record on the relevant record
date to receive interest due on an interest payment date that is on or prior to the redemption date), plus (3) the Make Whole Premium at the redemption date. 
 (d) The Notes may also be redeemed, as a whole, following certain Change of Control Offers, at the redemption price and subject to the conditions set forth in the last paragraph of Section 4.15 of
the Indenture. 
 6. Notice of Redemption. Notice of redemption will be mailed at least 30 days but not more than 60 days
(except as otherwise provided in the Indenture if the notice is issued in connection with a Legal Defeasance, Covenant Defeasance or Discharge) before the redemption date to each Holder whose Notes are to be redeemed at its registered address. If
mailed in the manner provided for in Section 3.03 of the Indenture, the notice of optional redemption shall be conclusively presumed to have been given whether or not a Holder receives such notice. Failure to give timely notice or any defect in
the notice shall not affect the validity of the redemption. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000 in excess of $2,000, unless all of the Notes held by a Holder are to be redeemed. On
and after the redemption date, interest and Additional Interest, if any, cease to accrue on the Notes or portions thereof called for redemption. The notice of redemption with respect to a redemption described in Paragraph 5(c) above need not set
forth the Make Whole Premium but only the manner of calculation thereof. 
 7. Mandatory Redemption. Except as set forth
in this Paragraph 7 and in Paragraph 8 below, the Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes or to repurchase the Notes at the option of the Holders. 

Following the Special Mandatory Redemption Trigger Event, the Initial Notes are subject to mandatory redemption as a whole, upon the
giving of prior notice to Holders and on the redemption date and for the redemption price set forth in Section 3.08 of the Indenture. 
 8. Repurchase at Option of Holder. 
 (a) Within 30 days following the
occurrence of a Change of Control, unless the Company has given a notice of redemption of all outstanding Notes, the Company shall make an offer (a “Change of Control Offer”) to repurchase all or any part (equal to $2,000 or an integral
multiple of $1,000 in excess of $2,000) of each Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest and Additional Interest, if any, to the date of
purchase (the “Change of Control Purchase Date”), subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Change of Control Purchase Date. Within
30 days following a Change of Control, unless the Company has given a notice of redemption of all outstanding Notes, the Company shall mail a notice of the Change of Control Offer to each Holder and the Trustee describing the transaction or
transactions that constitutes the Change of Control and setting forth the procedures governing the Change of Control Offer as required by Section 4.15 of the Indenture. 

  
 Exhibit 2 to
App. - 5 







 (b) When the aggregate amount of Collateral Net Proceeds exceeds $10 million, the Company
shall, within 60 days following the date on which such Collateral Net Proceeds first exceed such amount, use all Collateral Net Proceeds to make a Collateral Sale Offer to all Holders of Notes to purchase, on a pro rata basis, the maximum principal
amount of Notes that may be purchased out of the Collateral Net Proceeds. After completion of the Collateral Sale Offer, if there are any remaining Collateral Net Proceeds in excess of $10 million, the Company shall, within 60 days following the
consummation of such Collateral Sale Offer, use all remaining Collateral Net Proceeds to make a Second Priority Collateral Sale Offer to all holders of Second Priority Notes, to purchase, on a pro rata basis, the maximum principal amount of Second
Priority Notes that may be purchased out of such remaining Collateral Net Proceeds. The Company or any Restricted Subsidiary of the Company may invest the remaining Net Proceeds in any manner that is not prohibited by the Indenture. The offer price
in any Collateral Sale Offer or Second Priority Collateral Sale Offer will be equal to 100% of principal amount plus accrued and unpaid interest, if any, and Additional Interest, if any, thereon to the Settlement Date, subject to the right of
Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the Settlement Date, and will be payable in cash. 
 (c) On the 366th day after an Asset Sale other than a Collateral Disposition (or, at the Company’s option, any earlier date), if the aggregate amount of Excess Proceeds then exceeds $10 million, the
Company shall commence an offer to all Holders of Notes (an “Asset Sale Offer”) pursuant to Section 3.09 of the Indenture, and, subject to limitations contained in Section 4.07 of the Indenture, to all holders of Second Priority
Notes, as well as to all holders of any Pari Passu Indebtedness then outstanding, to purchase, on a pro rata basis, the maximum principal amount of Notes, Second Priority Notes and such Pari Passu Indebtedness that may be purchased out of the Excess
Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount of the Notes plus accrued and unpaid interest and Additional Interest, if any, thereon to the date of settlement, subject to the right of Holders of record on the
relevant record date to receive interest due on an Interest Payment Date that is on or prior to the date of settlement, in accordance with the procedures set forth in the Indenture. If any Excess Proceeds remain after consummation of an Asset Sale
Offer, the Company may use such remaining Excess Proceeds for any purpose not otherwise prohibited by the Indenture. 
 (d) If
the aggregate principal amount of Notes tendered into a Collateral Sale Offer or Asset Sale Offer exceeds the amount of proceeds allocated for the purchase of Notes, the Trustee will select the Notes to be purchased on a pro rata basis (with such
adjustments as may be deemed appropriate by the Trustee so that only Notes in denominations of $2,000, or integral multiples of $1,000 in excess of $2,000, shall be purchased) or, in the case of Global Notes, the Trustee will select Notes for
purchase based on DTC’s method that most nearly approximates a pro rata selection unless otherwise required by law. Holders of Notes that are the subject of an offer to purchase will receive a Collateral Sale Offer or an Asset Sale Offer from
the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” on the reverse of the Notes.

Date, if such default (a) is caused by a failure to pay principal of, or interest or premium, if any, on, such Indebtedness prior to the expiration of any grace period provided in such Indebtedness (a “Payment Default”) or
(b) results in the acceleration of such Indebtedness prior to its Stated Maturity and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a
Payment Default or the maturity of which has been so accelerated, aggregates $25 million or more; provided that if any such default is cured or waived or any such acceleration rescinded, within 20 days after the occurrence of such default or
declaration of such acceleration, or such Indebtedness is repaid and the Notes have not been accelerated, such Event of Default shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree;
(vii) failure by the Company or any of its Restricted Subsidiaries to pay final judgments aggregating in excess of $25 million (to the extent not covered by insurance by a reputable and creditworthy insurer as to which the insurer has not
disclaimed coverage), which judgments are not paid, discharged or stayed for a period of 60 consecutive days; (viii)(a) any Subsidiary Guarantee is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full
force and effect or (b) any Guarantor, or any Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its Subsidiary Guarantee, except in each case, by reason of the release of such Subsidiary Guarantee in
accordance with the provisions of the Indenture; (ix) certain events of bankruptcy, insolvency or reorganization with respect to the Company, any of the Company’s Restricted Subsidiaries that is a Significant Subsidiary of the Company or
any group of the Company’s Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary of the Company as specified in Section 6.01(i) or 6.01(j) of the Indenture; and (x) (a) the Security Documents for
any reason cease to create a valid and perfected first-priority Lien on any material portion of the Collateral (in each case, other than in accordance with the terms of the Indenture or the terms of the Security Documents) or (b) the Company or
any Subsidiary asserts in writing that any Lien created under the Security Documents is invalid or unenforceable. If any Event of Default occurs and is continuing, the Trustee, by notice to the Company, or the Holders of at least 25% in principal
amount of the then outstanding Notes, by notice to the Company and the Trustee, may declare all the Notes to be due and payable immediately. Notwithstanding the preceding, in the case of an Event of Default arising from such events of bankruptcy,
insolvency or reorganization described in Section 6.01(i) or 6.01(j) of the Indenture, all outstanding Notes will become due and payable immediately without further action or notice. Holders may not enforce the Indenture, the Notes or the
Security Documents except, subject to the Intercreditor Agreement, as provided in those documents. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any
trust or power conferred on it with respect to the Notes. The Trustee may withhold notice of any continuing Default or Event of Default from Holders if it determines that withholding notice is in their interest, except a Default or Event of Default
(i) relating to the payment of principal of, or interest or premium, if any, on, the Notes or (ii) in respect of a provision that under Section 9.02 of the Indenture cannot be amended without the consent of each Holder affected. The
Holders of a majority in principal amount of the Notes then outstanding by notice to the Trustee may on 

  
 Exhibit 2 to
App. - 8 







 
behalf of the Holders of all the Notes rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except
with respect to nonpayment of principal, interest, premium, or Additional Interest, if any, that have become due solely because of the acceleration) have been cured or waived. The Holders of a majority in principal amount of the Notes then
outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive (including, without limitation, in connection with a purchase of, or tender offer or exchange offer for, the Notes) any existing Default or Event of Default
and its consequences under the Indenture except a continuing Default or Event of Default in the payment of the principal of, or interest, premium, if any, or Additional Interest, if any, on, the Notes or in respect of a covenant that cannot be
amended without the consent of each Holder. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and, so long as any Notes are outstanding, upon any officer of the Company becoming aware of
any Default or Event of Default, the Company shall deliver to the Trustee a statement specifying such Default or Event of Default. 
 14. Defeasance and Discharge. The Notes are subject to defeasance and discharge upon the terms and conditions specified in the Indenture. 

15. No Recourse Against Others. No past, present or future director, officer, partner, employee, incorporator, manager or
unitholder or other owner of Capital Stock of the Company or any Guarantor, as such, shall have any liability for any obligations of the Company or any Guarantor under the Notes, the Subsidiary Guarantees or the Indenture or for any claim based on,
in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes. 

16. Security Documents and Intercreditor Agreement. At the time and subject to the conditions set forth in Article 11 of
the Indenture, payment of the principal of, premium, if any, interest and Additional Interest, if any, on the Notes may be secured by a Lien on the Collateral created by the Security Documents in favor of the Collateral Agent for the benefit of the
Holders, such Lien to have the relative priority with respect to the Collateral as may be provided in the Intercreditor Agreement. 
 17. Authentication. This Note shall not be valid until authenticated by the manual signature of an authorized signatory of the Trustee or an authenticating agent. 

18. Abbreviations. Customary abbreviations may be used in the name of a Holder 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). 

19. Removal of Restricted Notes Legend. Each holder of any Note evidenced by any Restricted Global Note, by its acceptance
thereof, (A) authorizes and consents to, (B) appoints the Company as its agent for the sole purpose of delivering such electronic messages, executing and delivering such instruments and taking such other actions, on such holder’s
behalf, as the Depository or the Trustee may require to effect, and (C) upon the request of the Company, agrees to deliver such electronic messages, execute and deliver such instruments and take such other actions as the Depository or the
Trustee may require, or as shall otherwise be necessary to effect,

 20. [Additional Rights of Holders of Transfer Restricted Securities. In addition to the rights provided to Holders of the Notes under the Indenture, Holders of Transfer Restricted Securities shall
have all the rights set forth in the Registration Rights Agreement dated as of February 23, 2012, among the Company, the Guarantors and the Initial Purchasers (the “Registration Rights Agreement”).]4

such funds to or for the account of the Company or disburse them to the Trustee or the Paying Agent for application to the mandatory redemption of the Initial Notes following the Special Mandatory Redemption Trigger Event.]5 

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