WHEREAS, the Original Indenture is incorporated herein by this reference, and the Original Indenture, as supplemented by this Third
Supplemental Indenture and any other supplemental indentures applicable to the Debt Securities created pursuant to this Third Supplemental Indenture, is herein called the “Indenture”; 

WHEREAS, under the Original Indenture, a new series of senior unsecured notes may at any time be established in or pursuant to a Board
Resolution, an Officer’s Certificate and one or more indentures supplemental to the Original Indenture; 
 WHEREAS, the Company
proposes to create under the Indenture a new series of senior unsecured notes and to add new provisions to, and change and eliminate certain existing provisions of, the Original Indenture in respect of such new series of senior unsecured notes; 

WHEREAS, additional senior unsecured notes of other series hereafter established, except as may be limited in the Original Indenture as at the
time supplemented and modified, may be issued from time to time pursuant to the Indenture as at the time supplemented and modified; and 

WHEREAS, all conditions necessary to authorize the execution and delivery of this Third Supplemental Indenture and make it a valid and binding
obligation of the Company in accordance with its terms, have been done or performed. 
 NOW, THEREFORE, THIS THIRD SUPPLEMENTAL INDENTURE
WITNESSETH: 
 For and in consideration of the premises set forth herein and for other good and valuable consideration the sufficiency of
which is hereby acknowledged, it is mutually agreed as follows:

provided, however, that additional Securities having identical terms and conditions as the Securities other than issue date, the issue price, the date from which interest thereon shall accrue, legends, if any, to be included








 
thereon and the first Interest Payment Date (the “Additional Securities”) may be issued from time to time in the future, without the consent of the Holders of the Securities, in

(a) the aggregate principal amount of such Additional Securities to be authenticated and delivered pursuant to the Indenture; 

(b) the issue date, the issue price, the first Interest Payment Date of such Additional Securities, the date from which interest shall accrue
and legends, if any, to be included thereon; and 
 (c) the CUSIP and ISIN numbers of the Additional Securities. 

The Securities and the Additional Securities, if any, shall be considered collectively as a single class for all purposes of the Indenture.
Holders of the Securities and the Additional Securities, if any, shall vote and consent together on all matters to which such Holders are entitled to vote or consent as one class, and none of the Holders of the Securities or the Additional
Securities, if any, shall have the right to vote or consent as a separate class on any matter to which such Holders are entitled to vote or consent. 

The Securities shall be issued in fully registered form without coupons, and only in minimum denominations of $2,000 and integral multiples of

Each Security shall be dated the date of authentication thereof and shall bear interest from the date of original issuance thereof or from the
most recent Interest Payment Date to which interest has been paid or duly provided for. 
 The Securities may have notations, legends or
endorsements required by law, stock exchange rule or usage or DTC rule or usage in addition to those set forth on Exhibit A. The Company and the Trustee shall approve the forms of the Securities and any notation, endorsement or legend on
them, such approval to be evidenced by the execution or authentication, respectively, and delivery of the Securities by the Company or the Trustee, respectively. The terms of the Securities set forth in Exhibit A are part of the terms of the

to any other secured Indebtedness merely because it has a junior priority with respect to the same collateral; 
 (8) the

 SECTION 2.02. New Definitions. The following
defined terms used herein with respect to the Securities shall, unless the context otherwise requires, have the meanings specified below. 

“Additional Assets” means (1) any property, plant or equipment or other assets (including Capital Stock of a Person engaged in

 (C) estimated proved crude
oil and natural gas reserves of the Company and its Restricted Subsidiaries reflected in such reserve report produced or disposed of since the date of such reserve report, and 

  
 4 








 (D) reductions in the estimated oil and natural gas reserves of the Company and
its Restricted Subsidiaries reflected in such reserve report since the date of such reserve report attributable to downward determinations of estimates of proved crude oil and natural gas reserves due to exploration, development or exploitation,
production or other activities conducted or otherwise occurring since the date of such reserve report which would, in accordance with standard industry practice, result in such determinations, in each case calculated in accordance with SEC
guidelines;

(1) minority interests; 

(2) any natural gas balancing liabilities of the Company and its Restricted Subsidiaries reflected in the Company’s latest
audited consolidated financial statements; 
 (3) the discounted future net revenue, calculated in accordance with SEC
guidelines (but utilizing prices and costs calculated in accordance with SEC guidelines as if the end of the most recent fiscal quarter preceding the date of determination for which such information is available to the Company were year-end),
attributable to reserves subject to participation interests, overriding royalty interests or other interests of third parties, pursuant to participation, partnership, vendor financing or other agreements then in effect, or which otherwise are
required to be delivered to third parties; 
 (4) to the extent included in the immediately preceding clause (a)(1) above,
the discounted future net revenue calculated in accordance with SEC guidelines (but utilizing prices 

  
 5 








 
and costs calculated in accordance with SEC guidelines as if the end of the most recent fiscal quarter preceding the date of determination for which such information is available to the Company
were year-end), attributable to reserves that are required to be delivered to third parties to fully satisfy the obligations of the Company and its Restricted Subsidiaries with respect to Volumetric Production Payments on the schedules specified
with respect thereto; and 
 (5) the discounted future net revenue, calculated in accordance with SEC guidelines,
attributable to reserves subject to Dollar-Denominated Production Payments that, based on the estimates of production included in determining the discounted future net revenue specified in the immediately preceding clause (a) (1) (but
utilizing prices and costs calculated in accordance with SEC guidelines as if the end of the most recent fiscal quarter preceding the date of determination for which such information is available to the Company were year-end), would be necessary to
satisfy fully the obligations of the Company and its Restricted Subsidiaries with respect to Dollar-Denominated Production Payments on the schedules specified with respect thereto. 

Whether or not the Company uses the successful efforts method of accounting or the full cost (or similar method) method of accounting, ACNTA
will be calculated as if the Company were using the full cost (or similar method) method of accounting. Any calculation of ACNTA shall be determined on a pro forma basis in a manner consistent with the pro forma adjustments contained in the
definition of Consolidated Coverage Ratio. 
 “Adjusted Treasury Rate” means, with respect to any Redemption Date, (i) the
yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the
Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity
corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after April 15, 2017, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and
the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month) or (ii) if such release (or any successor release) is not published during the week preceding the
calculation date or does not contain such yields, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for
such Redemption Date, in each case calculated on the third Business Day immediately preceding the Redemption Date, plus 0.50%. 

“Applicable Premium” means, with respect to a Security at any Redemption Date, the greater of (i) 1.00% of the principal amount
of such Security and (ii) the excess of (A) the present value at such Redemption Date of (1) the redemption price of such Security on April 15, 2017 (such redemption price being described in Section 3.02(c) of this Third
Supplemental Indenture) plus (2) all required remaining scheduled interest payments due on such Security through April 15, 2017 (excluding accrued and unpaid interest to the Redemption Date), computed using a discount rate equal to the
Adjusted Treasury Rate, over (B) the principal amount of such Security on such Redemption Date. Calculation of the Applicable Premium will be made by the Company or on behalf of the Company by such Person as the Company shall designate,
provided that such calculation or the correctness thereof shall not be a duty or obligation of the Trustee. 
 “Appalachian Area”
has the meaning assigned to such term in the Marcellus Joint Development Agreement as in effect on the Marcellus JV Closing Date and as amended or restated thereafter.

 (B)
if the Company or any Restricted Subsidiary has repaid, repurchased, redeemed, retired, defeased or otherwise discharged any Indebtedness since the beginning of such period or if any Indebtedness is to be repaid, repurchased, redeemed, retired

Temporary Cash Investments held by such Person or any Restricted Subsidiary of such Person, which cash or Temporary Cash Investments exist on the date of determination or will exist as a result of the transaction giving rise to the need to calculate
the Consolidated Coverage Ratio, will be included. 
 For purposes of this definition, whenever pro forma effect is to be given to an acquisition of
assets, the amount of income or earnings relating thereto and the amount of Consolidated Interest Expense associated with any Indebtedness Incurred in connection therewith, the pro forma calculations shall be determined in good faith by a
responsible financial or accounting Officer. If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the date of
determination had been the applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness, but if the remaining term of such Interest Rate Agreement is less than 12 months, then such Interest
Rate Agreement shall only be taken into account for that portion of the period equal to the remaining term thereof). 
 If any Indebtedness
is incurred under a revolving credit facility and is being given pro forma effect, the interest on such Indebtedness shall be calculated based on the average daily balance of such Indebtedness for the four fiscal quarters subject to the
pro forma calculation to the extent that such Indebtedness was incurred solely for working capital purposes.

such Indebtedness would not be so permitted to be Incurred pursuant Sections 4.05(a) or 4.05(b) of this Third Supplemental Indenture, such Indebtedness will be deemed to have been outstanding on the Issue Date, so that it is classified under
Section 4.05(b)(4) of this Third Supplemental Indenture. Calculations made after the Reinstatement Date of the amount available to be made as Restricted Payments under Section 4.06 of this Third Supplemental Indenture will be made as
though the covenants described under Section 4.06 of this Third Supplemental Indenture had been in effect since the Issue Date and throughout the Suspension Period. Accordingly, Restricted Payments made during the Suspension Period will reduce
the amount available to be made as Restricted Payments under Section 4.06(a) of this Third Supplemental Indenture. 
 The period of
time between the date of suspension of the covenants and the Reinstatement Date is referred to as the “Suspension Period.”

 The Company shall give the Trustee prompt written notice anytime that the Suspended Covenants do
not apply. Otherwise, the Trustee shall assume that the Suspended Covenants apply and shall have no duty to monitor compliance with such covenants on an ongoing basis. 

SECTION 4.03. Payment of Securities. The Company shall promptly pay the principal of and interest on the Securities on the dates
and in the manner provided in the Securities and in the Indenture. Principal and interest shall be considered paid on the date due if on such date the Trustee or the Paying Agent holds in accordance with the Indenture money sufficient to pay all
principal and interest then due. 
 The Company shall pay interest on overdue principal at the rate specified therefor in the Securities,
and it shall pay interest on overdue installments of interest at the same rate to the extent lawful. 
 SECTION 4.04. SEC
Reports. Whether or not the Company is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, so long as the Securities are outstanding, the Company shall file with the SEC (subject to the next sentence) and
provide, within 15 days after such filing, the Trustee and Securityholders with the annual and other reports as are specified in Sections 13 and 15(d) of the Exchange Act and applicable to a U.S. corporation subject to such Sections, and containing
all the information, audit reports and exhibits required for such reports (but without exhibits in the case of Securityholders). If at any time, the Company is not subject to the periodic reporting requirements of the Exchange Act for any reason,
the Company shall nevertheless continue filing the reports specified in the preceding sentence with the SEC unless the SEC will not accept such a filing. The Company agrees that it shall not take any action for the purpose of causing the SEC not to
accept any such filings. If, notwithstanding the foregoing, the SEC will not accept such filings for any reason, the Company shall post the reports specified in the preceding sentence on its website. The Company will also comply with the other
provisions of Section 314(a) of the Trust Indenture Act. 
 At any time that any of the Company’s Subsidiaries are Unrestricted
Subsidiaries, then the quarterly and annual financial information required by the preceding paragraph will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, of the financial
condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company, and a description of such Unrestricted Subsidiaries
in “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” 
 The Company will be deemed to
have furnished such reports to the trustees and the Holders of Securities if it has filed such reports with the SEC using the EDGAR filing system and such reports are publicly available. 

In addition, the Company shall furnish to the Holders of the Securities and to prospective investors, upon the requests of such Holders, any
information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act during any time that the Securities are not freely transferable under the Securities Act. Delivery of such reports, information and such documents to the
Trustee are for informational purposes only, and the Trustee’s receipt thereof shall not constitute constructive notice of any information contained therein. 

SECTION 4.05. Limitation on Indebtedness. 

(a) The Company shall not, and shall not permit any Restricted Subsidiary to, Incur, directly or indirectly, any Indebtedness; provided,
however, that the Company or a Restricted Subsidiary shall be entitled to Incur Indebtedness if, on the date of such Incurrence and after giving effect thereto on a pro forma basis, the Consolidated Coverage Ratio exceeds 2.25 to 1.0,

Subsidiary ceasing to be a Restricted Subsidiary or any subsequent transfer of such Indebtedness (other than to the Company or a Restricted Subsidiary) shall be deemed, in each case, to constitute the Incurrence of such Indebtedness by the obligor
thereon not permitted by this clause (2), (B) if the Company is the obligor on such Indebtedness, and a Subsidiary Guarantor is not the obligee, such Indebtedness is expressly subordinated to the prior payment in full in cash of all obligations

to Section 4.05(a) of this Third Supplemental Indenture, the Company, in its sole discretion, shall be entitled to divide and classify (or

Incurrence of such Indebtedness; provided, however, that if any such Indebtedness denominated in a different currency is subject to a Currency Agreement with respect to U.S. dollars covering all principal, premium, if any, and interest
payable on such Indebtedness, the amount of such Indebtedness expressed in U.S. dollars shall be as provided in such Currency Agreement. The principal amount of any Refinancing Indebtedness Incurred in the same currency as the Indebtedness being
Refinanced shall be the U.S. Dollar Equivalent of the Indebtedness Refinanced, except to the extent that (1) such U.S. Dollar Equivalent was determined based on a Currency Agreement, in which case the Refinancing Indebtedness shall be
determined in accordance with the preceding sentence, and (2) the principal amount of the Refinancing Indebtedness exceeds the principal amount of the Indebtedness being Refinanced, in which case the U.S. Dollar Equivalent of such excess
shall be determined on the date such Refinancing Indebtedness is Incurred. 
 SECTION 4.06. Limitation on Restricted Payments.
(a) The Company shall not, and shall not permit any Restricted Subsidiary, directly or indirectly, to make a Restricted Payment if at the time the Company or such Restricted Subsidiary makes such Restricted Payment: 

(1) a Default shall have occurred and be continuing (or would result therefrom); 

(2) the Company is not entitled to Incur an additional $1.00 of Indebtedness under Section 4.05(a) of this Third

Company’s equity interest in such Subsidiary) of the fair market value of the net assets of such Unrestricted Subsidiary at the time such Unrestricted Subsidiary is designated a Restricted Subsidiary or is sold; provided, however, that
such amount shall not exceed, in the case of any Unrestricted Subsidiary other than the Marcellus Midstream Owner, the amount of Investments (excluding Permitted Investments) previously made (and treated as a Restricted Payment) by the Company or

paid in cash shall be equal to its face amount. The fair market value of any assets or securities that are required to be valued at the time of such Restricted Payment by this Section 4.06 shall be evidenced by an Officer’s Certificate
which shall be delivered to the Trustee not later than ten Business Days following the date of the making of any Restricted Payment. Such Officer’s Certificate shall state that such Restricted Payment is permitted together with a copy of any
related resolutions of the Board of Directors. 
 The Company shall not permit any Unrestricted Subsidiary to become a Restricted Subsidiary

Restricted Payment in such amount would be permitted at such time and if such Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. Unrestricted Subsidiaries will not be subject to any of the restrictive covenants set forth in
this Third Supplemental Indenture. 
 SECTION 4.07. Limitation on Restrictions on Distributions from Restricted Subsidiaries. The
Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create or otherwise cause or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to
(a) pay dividends or make any other distributions on its Capital Stock to the Company or a Restricted Subsidiary or pay any Indebtedness owed to the Company; provided that the priority of any Preferred Stock in receiving dividends or
liquidating distributions being paid on common stock shall not be deemed a restriction of the ability to make distributions of Capital Stock, (b) make any loans or advances to the Company; provided that the subordination of loans or
advances made to the Company or any Restricted Subsidiary to other Indebtedness incurred by the Company or any Restricted Subsidiary shall not be deemed a restriction of the ability to make loans or advances or (c) transfer any of its property
or assets to the Company, except: 
 (1) with respect to clauses (a), (b) and (c) above, 

(A) any encumbrance or restriction pursuant to an agreement in effect at or entered into on the Issue Date including, for the
avoidance of doubt, the Credit Agreement and the Existing Senior Notes Indenture; 
 (B) any encumbrance or restriction with
respect to a Restricted Subsidiary pursuant to an agreement relating to any Indebtedness Incurred by such Restricted Subsidiary, or otherwise binding on such Restricted Subsidiary, on or prior to 

  
 49 








 
the date on which such Restricted Subsidiary was acquired or was so designated by the Company or any Restricted Subsidiary (other than Indebtedness Incurred as consideration in, or to provide all
or any portion of the funds or credit support utilized to consummate, and other than any encumbrance or restriction entered into in contemplation of, the transaction or series of related transactions pursuant to which such Restricted Subsidiary

restriction relates only to property or assets owned by such Foreign Subsidiary and is not materially more restrictive to such Foreign Subsidiary than is customary in comparable financings, as determined in good faith by the Board of Directors; 

(G) any encumbrance or restriction pursuant to provisions in agreements or instruments which prohibit the payment of dividends

security agreements, mortgages, purchase money agreements or similar instruments; 
 (C) Permitted Liens or Liens securing

 SECTION 4.08. Limitation on Sales of Assets
and Subsidiary Stock. 
 (a) The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly,
consummate any Asset Disposition unless (1) the Company or such Restricted Subsidiary 

  
 51 








 
receives consideration (including by way of relief from, or by any Person assuming responsibilities for any liabilities, contingent or otherwise) at the time of such Asset Disposition at least
equal to the fair market value (including as to the value of all non-cash consideration), as determined in good faith by the Board of Directors or an executive officer of the Company or such Restricted Subsidiary with the responsibility for such
transaction which determination shall be conclusive evidence of compliance with this provision, of the shares and assets subject to such Asset Disposition; (2) at least 75% of the consideration thereof received by the Company or such Restricted
Subsidiary is in the form of cash or cash equivalents or Additional Assets or any combination thereof; and (3) an amount equal to 100% of the Net Available Cash from such Asset Disposition is applied by the Company (or such Restricted
Subsidiary, as the case may be) (A) to the extent the Company elects (or is required by the terms of any Senior Indebtedness), to prepay, repay, redeem or purchase Indebtedness of the Company or a Subsidiary Guarantor (other than any
Disqualified Stock), in each case other than Indebtedness owed to the Company or a Subsidiary of the Company, within 540 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash; (B) to the extent the
Company elects, to acquire Additional Assets or to make capital expenditures in the Oil and Gas Business, in each case within 540 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash; and (C) to
the extent of the balance of such Net Available Cash after any application in accordance with either or both of clauses (A) and (B), to make an Offer to the Holders of the Securities (and to holders of other Senior Indebtedness of the Company
or of any Restricted Subsidiary designated by the Company) to purchase Securities (and such other Senior Indebtedness of the Company or of any Restricted Subsidiary) pursuant to and subject to the conditions of this Third Supplemental Indenture.

 Notwithstanding the foregoing, the 75% limitation referred to in Section 4.08(a)(2) of this Third Supplemental Indenture shall be
deemed satisfied with respect to any Asset Disposition in which the cash or cash equivalents portion of the consideration received therefrom, determined in accordance with the foregoing provision on an after-tax basis, is equal to or greater than
what the after-tax cash proceeds would have been had such Asset Disposition complied with such 75% limitation. 
 The requirement of
Section 4.08(a)(3)(B) of this Third Supplemental Indenture shall be deemed to be satisfied if an agreement (including a lease, whether a capital lease or an operating lease) committing to make the acquisitions or expenditures referred to
therein is entered into by the Company or a Restricted Subsidiary within the time period specified in such clause and such Net Available Cash is subsequently applied in accordance with such agreement within six months following such agreement. 

Notwithstanding the foregoing provisions of this Section 4.08, the Company and the Restricted Subsidiaries shall not be required to apply
any Net Available Cash in accordance with this Section 4.08(a) except to the extent that the aggregate Net Available Cash from all Asset Dispositions which is not applied in accordance with this Section 4.08(a) exceeds $50.0 million.
Pending application of Net Available Cash pursuant to this Section 4.08(a), such Net Available Cash may be invested in any manner that is not prohibited under this Third Supplemental Indenture. 

For the purposes of this Section 4.08(a), the following are deemed to be cash or cash equivalents: (i) any liabilities (as shown on
the Company’s or such Restricted Subsidiary’s most recent balance sheet) of the Company or any Restricted Subsidiary (other than liabilities that are subordinated to the Securities or any Subsidiary Guaranty) that are assumed by the
transferee of any such assets pursuant to a customary novation agreement or similar agreement that releases the Company or such Restricted Subsidiary from all further liability, (ii) securities received by the Company or any Restricted
Subsidiary from the transferee that are converted within 180 days by the Company or such Restricted Subsidiary into cash, to the extent of cash received in that conversion, and (iii) accounts receivable of a business retained by the Company or
any Restricted Subsidiary, as the case may be, following the sale of such business, provided that such accounts receivable are not (A) past due more than 30 days and (B) do not have a payment greater than 90 days from the date of the
invoice creating such accounts receivable. 

  
 52 








 (b) In the event of an Asset Disposition that requires the purchase of Securities (and other
Senior Indebtedness of the Company or a Subsidiary Guarantor) pursuant to Section 4.08(a)(3)(C) of this Third Supplemental Indenture, the Company shall purchase Securities tendered pursuant to an offer by the Company for the Securities (and
such other Senior Indebtedness) (the “Offer”) made on or before the 541st day after the later of the date of such Asset Disposition or the receipt of such Net Available Cash at a
purchase price of 100% of their principal amount (or, in the event such other Senior Indebtedness of the Company or such Subsidiary Guarantor was issued with original issue discount greater than 2.5%, 100% of the accreted value thereof), without
premium, plus accrued but unpaid interest (or, in respect of such other Senior Indebtedness of the Company or such Subsidiary Guarantor, such lesser price, if any, as may be provided for by the terms of such Senior Indebtedness) in accordance with
the procedures (including prorating in the event of oversubscription) set forth in Section 4.08(c) of this Third Supplemental Indenture; provided, however, that the procedures for making an offer to holders of other Senior Indebtedness
will be as provided for by the terms of the agreements governing such Senior Indebtedness. If the aggregate purchase price of the Securities and other Senior Indebtedness tendered pursuant to the Offer exceeds the Net Available Cash allotted to
their purchase, the Company shall select the Securities and other Senior Indebtedness to be purchased on a pro rata basis but in round denominations, which in the case of the Securities will be minimum denominations of $2,000 principal amount and
any integral multiple of $1,000 in excess thereof. The Company shall not be required to make an Offer to purchase Securities (and other Senior Indebtedness of the Company or a Subsidiary Guarantor) pursuant to this Section 4.08 if the Net
Available Cash available therefor is less than $50.0 million (which lesser amount shall be carried forward for purposes of determining whether such an Offer is required with respect to the Net Available Cash from any subsequent Asset Disposition).
Upon completion of such an Offer, Net Available Cash shall be deemed to be reduced by the aggregate amount of such Offer (whether or not accepted) and any then remaining Net Available Cash following such offer may be used for any purpose not
prohibited by this Third Supplemental Indenture. 
 (c) (1) Promptly, and in any event within 10 days after the Company becomes obligated to
make an Offer, the Company shall deliver to the Trustee and send, by first-class mail or otherwise deliver in accordance with the procedures of DTC to each Holder, a written notice stating that the Holder may elect to have his Securities purchased
by the Company either in whole or in part (subject to prorating as described in Section 4.08(b) of this Third Supplemental Indenture in the event the Offer is oversubscribed) in minimum denominations of $2,000 principal amount and any integral
multiple of $1,000 in excess thereof, at the applicable purchase price. The notice shall specify a purchase date not less than 30 days nor more than 60 days after the date of such notice (the “Purchase Date”) and shall contain such
information concerning the business of the Company which the Company in good faith believes will enable such Holders to make an informed decision (which at a minimum will include (A) the most recently filed Annual Report on Form 10-K (including
audited consolidated financial statements) of the Company, the most recent subsequently filed Quarterly Report on Form 10-Q and any Current Report on Form 8-K of the Company filed subsequent to such Quarterly Report, other than Current Reports
describing Asset Dispositions otherwise described in the offering materials (or corresponding successor reports), (B) a description of material developments in the Company’s business subsequent to the date of the latest of such Reports and
(C) if material, appropriate pro forma financial information) and all instructions and materials necessary to tender Securities pursuant to the Offer, together with the information contained in clause (3). 

(2) Not later than the date upon which written notice of an Offer is delivered to the Trustee as provided above, the Company
shall deliver to the Trustee an Officer’s Certificate as to (A) the amount of the Offer (the “Offer Amount”), including information as to 

  
 53 








 
any other Senior Indebtedness included in the Offer, (B) the allocation of the Net Available Cash from the Asset Dispositions pursuant to which such Offer is being made and (C) the
compliance of such allocation with the provisions of Section 4.08(a) and (b) of this Third Supplemental Indenture. On such date, the Company shall also irrevocably deposit with the Trustee or with a Paying Agent (or, if the Company is
acting as its own Paying Agent, segregate and hold in trust) in Temporary Cash Investments, maturing on the last day prior to the Purchase Date or on the Purchase Date if funds are immediately available by open of business, an amount equal to the
Offer Amount to be held for payment in accordance with the provisions of this Section. If the Offer includes other Senior Indebtedness, the deposit described in the preceding sentence may be made with any other paying agent pursuant to arrangements
satisfactory to the Trustee. Upon the expiration of the period for which the Offer remains open (the “Offer Period”), the Company shall deliver to the Trustee for cancellation the Securities or portions thereof which have been properly
tendered to and are to be accepted by the Company. The Trustee shall, on the Purchase Date, mail or deliver payment (or cause the delivery of payment) to each tendering Holder in the amount of the purchase price. In the event that the aggregate
purchase price of the Securities delivered by the Company to the Trustee is less than the Offer Amount applicable to the Securities, the Trustee shall deliver the excess to the Company immediately after the expiration of the Offer Period for
application in accordance with this Section 4.08. 
 (3) Holders electing to have a Security purchased shall be
required to surrender the Security, with an appropriate form duly completed, to the Company at the address specified in the notice at least three Business Days prior to the Purchase Date. Holders shall be entitled to withdraw their election if the
Trustee or the Company receives not later than one Business Day prior to the Purchase Date, a telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security which was delivered for purchase by the
Holder and a statement that such Holder is withdrawing his election to have such Security purchased. Holders whose Securities are purchased only in part shall be issued new Securities equal in principal amount to the unpurchased portion of the
Securities surrendered. 
 (4) At the time the Company delivers Securities to the Trustee which are to be accepted for
purchase, the Company shall also deliver an Officer’s Certificate stating that such Securities are to be accepted by the Company pursuant to and in accordance with the terms of this Section 4.08. A Security shall be deemed to have been
accepted for purchase at the time the Trustee, directly or through an agent, mails or delivers payment therefor to the surrendering Holder. 

(d) The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other
securities laws or regulations in connection with the repurchase of Securities pursuant to this Section. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section, the Company shall comply with
the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section by virtue of its compliance with such securities laws or regulations. 

SECTION 4.09. Limitation on Affiliate Transactions. (a) The Company shall not, and shall not permit any Restricted Subsidiary to,
enter into or permit to exist any transaction (including the purchase, sale, lease or exchange of any property, employee compensation arrangements or the rendering of any service) with, or for the benefit of, any Affiliate of the Company involving
aggregate consideration in excess of $5.0 million (an “Affiliate Transaction”) unless (1) the terms of the Affiliate Transaction are no less favorable to the Company or such Restricted Subsidiary than those that could be obtained at
the time of the Affiliate Transaction in arm’s-length dealings with a Person who is not an Affiliate and if, in the good faith judgment of the Board of Directors (whose determination shall be conclusive), no comparable


  
 54 








 
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; (2) if such Affiliate Transaction involves an amount in excess of $25.0 million, the terms of the Affiliate Transaction are set forth in writing and a majority of the non-employee directors of the Company disinterested with respect to
such Affiliate Transaction have determined in good faith that the criteria set forth in clause (1) are satisfied and have approved the relevant Affiliate Transaction as evidenced by a resolution of the Board of Directors; and (3) if such
Affiliate Transaction involves an amount in excess of $50.0 million, the Board of Directors shall also have received a written opinion from an Independent Qualified Party to the effect that such Affiliate Transaction is fair, from a financial
standpoint, to the Company and the Restricted Subsidiaries or is not less favorable to the Company and the Restricted Subsidiaries than could reasonably be expected to be obtained at the time in an arm’s-length transaction with a Person who was
not an Affiliate. 
 (b) The provisions of Section 4.09(a) of this Third Supplemental Indenture shall not prohibit: 

(1) any Investment (other than an Investment described in clauses (2), (13) and (19) of the definition of “Permitted
Investment”) or other Restricted Payment, in each case permitted to be made pursuant to Section 4.06 of this Third Supplemental Indenture; 

(2) any issuance of securities, or other payments, awards or grants in cash, securities or otherwise pursuant to, or the funding of, employment

 (3) loans or advances to officers or employees
in the ordinary course of business in accordance with the past practices of the Company or the Restricted Subsidiaries not to exceed $5.0 million in the aggregate outstanding at any one time, in each case only as permitted by Section 402 of the
Sarbanes-Oxley Act of 2002; 
 (4) the payment of reasonable fees to directors of the Company and the Restricted Subsidiaries who are not
employees of the Company or the Restricted Subsidiaries, the reimbursement of reasonable out-of-pocket expenses incurred by, directors of the Company and the Restricted Subsidiaries in attending meetings of such directors and indemnification
payments made to officers, directors and employees of the Company or any Subsidiary pursuant to charter, bylaw, statutory or contractual provisions; 

(5) any transaction between or among the Company and a Restricted Subsidiary or joint venture or similar entity which would constitute an
Affiliate Transaction solely because the Company or a Restricted Subsidiary owns an equity interest in or otherwise controls such Restricted Subsidiary, joint venture or similar entity; (6) the issuance or sale of any Capital Stock (other than
Disqualified Stock) of the Company to, or the receipt by the Company of any capital contribution from, its stockholders or Affiliates; 
 (7)
any agreement as in effect on the Issue Date and described in the Prospectus Supplement or any amendments or other modifications, renewals or extensions of any such agreement (so long as such amendments or other modifications, renewals or extensions
are not materially less favorable to the Company or the Restricted Subsidiaries) and the transactions evidenced thereby;

course of business, so long as the terms of any such transaction are approved by a majority of the members of the Board of Directors who are disinterested with respect to such transaction; 

(9) transactions contemplated by the Marcellus JV Documents, the KKR Participation Agreement, the EXCO/HGI MLP Documents or the BG JV
Documents, in each case as in effect on the Issue Date, in the ordinary course of business and otherwise in compliance with the terms of this Third Supplemental Indenture, which are fair to the Company and its Restricted Subsidiaries, in the
reasonable determination of the Board of Directors of the Company, an executive officer of the Company or an executive officer of such Restricted Subsidiary with responsibility for such transaction (whose determination shall be conclusive evidence
of compliance with this provision) and amendments, modifications, supplements, extensions or renewals of such agreements from time to time, so long as any such amendment, modification, supplement, extension or renewal is not more disadvantageous to
the Holders in any material respect in the good faith judgment of the Board of Directors of the Company, when taken as a whole, than the terms of such agreements in effect on the Issue Date; 

(10) transactions with Unrestricted Subsidiaries, customers, clients, suppliers, or purchasers or sellers of goods or services in each case in
the ordinary course of business and otherwise in compliance with this Third Supplemental Indenture, which are fair to the Company and its Restricted Subsidiaries, in the reasonable determination of the Board of Directors of the Company, an executive

reasonably have been obtained at such time from an unaffiliated party;

voting as a director of the Company on any matter involving such other Person; 
 (12) any transaction in which the Company or any of its
Restricted Subsidiaries as the case may be, deliver to the Trustee, a written opinion from an Independent Qualified Party to the effect that such Affiliate Transaction is fair, from a financial standpoint, to the Company and the Restricted
Subsidiaries or is not less favorable to the Company and the Restricted Subsidiaries than could reasonably be expected to be obtained at the time in an arm’s-length transaction with a Person who was not an Affiliate;

course of business, except for guarantees of Indebtedness in respect of borrowed money; and

Person in its capacity as a holder of Indebtedness or Capital Stock of the Company or any Restricted Subsidiary where such Person is treated no more favorably than the other holders of Indebtedness or Capital Stock of the Company or such Restricted
Subsidiary.

providing that the Securities or the Subsidiary Guaranty, as the case may be, shall be secured equally and ratably with the obligations so secured (or in the case of Subordinated Obligations, prior or senior thereto, with the same relative priority

Affiliate of the Company solely for the purpose and with the sole effect of reincorporating the Company in another jurisdiction under the law of the United States or any political subdivision or State thereof. 

For purposes of this Section 5.02, the sale, lease, conveyance, assignment, transfer or other disposition in a single transaction or
series of related transactions of all or substantially all of the properties and assets of one or more Subsidiaries of the Company, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or
substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company. 

  
 59 








 The Successor Company shall be the successor to the Company and shall succeed to, and be
substituted for, and may exercise every right and power of, the Company under the Indenture, and the predecessor Company, except in the case of a lease, shall be released from the obligation to pay the principal of and interest on the Securities.

 (b) The Company shall not permit any Subsidiary Guarantor to consolidate with or merge with or into, or convey, transfer or lease, in one
transaction or series of transactions, all or substantially all of its assets to any Person unless: 
 (1) the resulting,
surviving or transferee Person (if not such Subsidiary) shall be a Person organized and existing under the laws of the jurisdiction under which such Subsidiary was organized or under the laws of the United States, or any State thereof or the
District of Columbia, and such Person shall expressly assume, by an amendment to the Indenture, in a form satisfactory to the Trustee, all the obligations of such Subsidiary, if any, under its Subsidiary Guaranty (except in the case of a Subsidiary
Guarantor (x) that has been disposed of in its entirety to another Person (other than to the Company or any other Subsidiary of the Company), whether through a merger, consolidation or sale of Capital Stock or assets, (y) that, as a result
of the disposition of all or a portion of its Capital Stock, ceases to be a Subsidiary or (z) that has otherwise been released from its Subsidiary Guaranty in accordance with the terms thereof and the terms of this Third Supplemental Indenture,
in each case, if in connection therewith the Company provides an Officer’s Certificate to the Trustee to the effect that the Company will comply with its obligations under Section 4.08 of this Third Supplemental Indenture in respect of
such disposition); 
 (2) immediately after giving effect to such transaction or transactions on a pro forma basis
(and treating any Indebtedness which becomes an obligation of the resulting, surviving or transferee Person as a result of such transaction as having been issued by such Person at the time of such transaction), no Default shall have occurred and be
continuing; and 
 (3) the Company delivers to the Trustee an Officer’s Certificate and an Opinion of Counsel, each
stating that such consolidation, merger or transfer and such Guaranty Agreement, if any, complies with the Indenture. 
 The successor
Subsidiary Guarantor shall be the successor to the Subsidiary Guarantor and shall succeed to, and be substituted for, and may exercise every right and power of, the Subsidiary Guarantor under the Indenture, and the predecessor Subsidiary Guarantor,
except in the case of a lease, shall be released from the obligation to pay the principal of and interest on the Securities. 
 (c)
Notwithstanding the foregoing, any Subsidiary Guarantor may merge with or into or transfer all or part of its properties and assets to a Subsidiary Guarantor or the Company or merge with a Subsidiary Guarantor of the Company, as long as
(1) immediately after giving effect to such transaction or transactions on a pro forma basis (and treating any Indebtedness which becomes an obligation of the resulting, surviving or transferee Person as a result of such transaction as
having been issued by such Person at the time of such transaction), no Default shall have occurred and be continuing and (2) the amount of Indebtedness of such Subsidiary Guarantor and its Restricted Subsidiaries is not materially increased
thereby.

 ARTICLE 6 

Defaults and Remedies 

SECTION 6.01. Original Indenture. Article V and 602 and 1004 of the Original Indenture shall not apply to the Securities and hereafter
shall be void and of no force and effect and any reference in the Original Indenture to Article V shall be deemed to refer to Article 6 of this Third Supplemental Indenture and any reference in the Original Indenture to Sections 602 and 1004
thereof shall be deemed to refer to Section 6.05 of this Third Supplemental Indenture. 
 SECTION 6.02. Events of Default. An
“Event of Default” occurs if: 
 (1) the Company defaults in any payment of interest on any Security when the same
becomes due and payable, and such default continues for a period of 30 days; 
 (2) the Company (A) defaults in the
payment of the principal of any Security when the same becomes due and payable at its Stated Maturity, upon optional redemption, upon declaration of acceleration or otherwise, or (B) fails to redeem or purchase Securities when required pursuant
to this Third Supplemental Indenture or the Securities; 
 (3) the Company fails to comply with Section 5.02 of this
Third Supplemental Indenture above; 
 (4) the Company fails to comply with Section 4.04, 4.05, 4.06, 4.07, 4.08, 4.09,
4.10, 4.11, 4.12, 4.13, or 4.14 of this Third Supplemental Indenture (other than a failure to purchase Securities when required under Section 4.08 or 4.11) and such failure continues for 60 days after the notice specified below; 

(5) the Company or any Subsidiary Guarantor fails to comply with any of its agreements in the Indenture (other than those
referred to in clause (1), (2), (3) or (4) above) and such failure continues for 90 days after the notice specified below; 

(6) Indebtedness of the Company, any Subsidiary Guarantor or any Significant Subsidiary is not paid within any applicable
grace period after final maturity or is accelerated by the Holders thereof because of a default and the total amount of such Indebtedness unpaid or accelerated exceeds $25.0 million, or its foreign currency equivalent at the time, provided,
that if any such default is cured or waived or any such acceleration rescinded, or such Indebtedness is repaid, within a period of 30 days from the continuation of such default beyond the applicable grace period or the occurrence of such
acceleration, as the case may be, such Event of Default under the Indenture and any consequential acceleration of the Securities shall be automatically rescinded; 

(7) the Company, any Subsidiary Guarantor or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy
Law: 
 (A) commences a voluntary case; 

(B) consents to the entry of an order for relief against it in an involuntary case; 

  
 61 








 (C) consents to the appointment of a Custodian of it or for all or substantially

under any foreign laws relating to insolvency; 
 (8) a court of competent jurisdiction enters an order or decree under any
Bankruptcy Law that: 
 (A) is for relief (with respect to the petition commencing such case) against the Company, a
Subsidiary Guarantor or any Significant Subsidiary in an involuntary case; 
 (B) appoints a Custodian of the Company, a
Subsidiary Guarantor or any Significant Subsidiary or for all or substantially all of its property; or

judgment; or 
 (10) any Subsidiary Guaranty ceases to be in full force and effect (other than in accordance with the terms
of such Subsidiary Guaranty) or any Subsidiary Guarantor denies or disaffirms its obligations under its Subsidiary Guaranty, as the case may be. 

The foregoing will constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary
or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body. 

The term “Bankruptcy Law” means Title 11, United States Code, or any similar Federal or state law for the relief of debtors.
The term “Custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law. 

A Default under clause (4) or (5) above is not an Event of Default until the Company receives from the Trustee or the holders of at
least 25% in principal amount of the outstanding Securities a notice specifying the default, demanding that the default be remedied and stating that such notice is a “Notice of Default” and the Company does not cure such Default within the
time specified above after receipt of such notice. 
 The Company shall deliver to the Trustee, within 30 days after becoming aware of the
occurrence thereof, written notice in the form of an Officer’s Certificate of any Event of Default under clause (6) or (10) above and any event which with the giving of notice or the lapse of time would become an Event of Default
under clause (4), (5) or (9) above, its status and what action the Company is taking or proposes to take with respect thereto. 

  
 62 








 SECTION 6.03. Acceleration. If an Event of Default (other than an Event of Default
specified in Section 6.02(7) or (8) of this Third Supplemental Indenture with respect to the Company) occurs and is continuing, the Trustee by notice (as specified below) to the Company, or the Holders of at least 25% in principal amount
of the outstanding Securities by notice (as specified below) to the Company and the Trustee, may declare the principal of and accrued but unpaid interest on all the Securities to be due and payable by notice in writing to the Company specifying such
Event of Default and stating that such notice is a “Notice of Acceleration.” Upon such a declaration, such principal and interest shall be due and payable immediately. If an Event of Default specified in Section 6.02(7) or (8) of
this Third Supplemental Indenture with respect to the Company occurs and is continuing, the principal of and interest on all the Securities shall ipso facto become and be immediately due and payable without any declaration or other act on the part
of the Trustee or any Securityholders. The Holders of a majority in principal amount of the outstanding Securities by notice to the Trustee may waive an existing or past Event of Default and its consequences and may also rescind any such
acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived, except nonpayment of principal or interest that has become due solely because of
acceleration. No such rescission shall affect any subsequent Default or impair any right consequent thereto. 
 SECTION 6.04. 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 or interest on the Securities or to enforce the performance of any provision of the Securities or the
Indenture. 
 The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the
proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No
remedy is exclusive of any other remedy. All available remedies are cumulative. 
 SECTION 6.05. Control by Majority. The Holders of
a majority in principal amount of the outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the
Trustee may refuse to follow any direction that conflicts with law or the Indenture or, subject to Section 601 of the Original Indenture, that the Trustee determines is unduly prejudicial to the rights of other Securityholders or would involve
the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Subject to Section 601 of the Original Indenture, in case an
Event of Default occurs and is continuing, the Trustee will have no obligation to exercise any of the rights or powers under the Indenture at the request or direction of the Securityholders unless prior to taking any action hereunder, such
Securityholders have offered indemnification or security satisfactory to Trustee against all losses, liability and expenses caused by taking or not taking such action. 

SECTION 6.06. Limitation on Suits. Except to enforce the right to receive payment of principal, premium (if any) or interest when due,
no Securityholder may pursue any remedy with respect to this Indenture or the Securities unless: 
 (1) such Holder or
Holders gives to the Trustee written notice stating that an Event of Default is continuing; 
 (2) the Holders of at least
25% in principal amount of the outstanding Securities make a written request to the Trustee to pursue the remedy; 

  
 63 








 (3) such Holder or Holders offer to the Trustee security or indemnity
satisfactory to Trustee against any loss, liability or expense; 
 (4) the Trustee does not comply with the request within
60 days after receipt of the request and the offer of security or indemnity; and 
 (5) the Holders of a majority in
principal amount of the outstanding Securities do not give the Trustee a direction inconsistent with the request during such 60-day period. 

A Securityholder may not use this Indenture to prejudice the rights of another Securityholder or to obtain a preference or priority over
another Securityholder. 
 SECTION 6.07. Rights of Holders to Receive Payment. Notwithstanding any other provision of the Indenture,
the right of any Holder to receive payment of principal of and interest on the Securities held by such Holder, on or after the respective due dates expressed in the Securities, 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 6.02(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount then due and
owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 607 of the Original Indenture. 

SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may 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 and the Securityholders allowed in any judicial proceedings relative to the Company, its creditors or its property and, unless prohibited by law or applicable regulations, participate
as a member of any official committee of creditors appointed in such matter and may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial
proceeding is hereby authorized by each Holder to make 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 it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 607 of the Original Indenture. 

Priorities. If the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in the
following order: 
 FIRST: to the Trustee for amounts due under Section 607 of the Original Indenture; 

SECOND: to Securityholders for amounts due and unpaid on the Securities for principal and interest, ratably, without preference
or priority of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and 

THIRD: to the Company. 

The Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this Section. At least 15 days before such
record date, the Company shall mail or otherwise deliver in accordance with the procedures of DTC to each Securityholder and the Trustee a notice that states the record date, the payment date and amount to be paid. 

  
 64 








 SECTION 6.10. Undertaking for Costs. In any suit for the enforcement of any right or
remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and
the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, 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 pursuant to Section 6.07 of this Third Supplemental Indenture or a suit by Holders of more than 10% in principal amount of the Securities. 

SECTION 6.11. Waiver of Stay or Extension Laws. The Company (to the extent it may lawfully do so) shall not at any time insist upon, or
plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to
the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of
every such power as though no such law had been enacted. 
 SECTION 6.12. Notice of Defaults. If a Default occurs, is continuing and
is known to the Trustee, the Trustee shall mail or otherwise deliver in accordance with the procedures of DTC to each Holder of the Securities notice of the Default within 90 days of the Trustee’s knowledge of such Default. Except in the case
of a Default in the payment of principal or of interest of or on any Securities, the Trustee may withhold notice if an so long it determines that withholding notice is not opposed to the interest of the Holders of the Securities. In addition, the
Company shall deliver to the Trustee, within 120 days after the end of each fiscal year, a certificate signed by its principal executive officer, principal financial officer or principal accounting officer, stating whether or not, to the knowledge
of such officer, the Company is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Company
shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge. 
 ARTICLE 7

 Discharge of Indenture; Defeasance 

SECTION 7.01. Original Indenture. Articles IV and XIII of the Original Indenture shall not apply to the Securities and hereafter shall
be void and of no force and effect. 
 SECTION 7.02. Discharge of Liability on Securities; Defeasance. (a) When (1) the
Company delivers to the Trustee all outstanding Securities (other than Securities replaced pursuant to Section 306 of the Original Indenture) for cancellation or (2) all outstanding Securities have become due and payable, whether at
maturity or on a Redemption Date as a result of the mailing or delivery in accordance with the procedures of DTC of a notice of redemption pursuant to Article 3 hereof (it being understood that all outstanding Securities will be deemed to be due and
payable on such Redemption Date upon the mailing or delivery in accordance with the procedures of DTC of such notice of redemption), and, in the case of clause (2), the Company irrevocably deposits with the Trustee funds sufficient to pay at
maturity or upon redemption all outstanding Securities, including interest thereon to maturity or such Redemption Date (other than Securities replaced pursuant to Section 306 of the Original Indenture), and if in either case the Company pays
all other sums payable hereunder by the Company, then this Third Supplemental Indenture 

  
 65 








 
shall, subject to Section 7.02(c) of this Third Supplemental Indenture, cease to be of further effect. The Trustee shall acknowledge satisfaction and discharge of the Indenture on demand of
the Company accompanied by an Officer’s Certificate and an Opinion of Counsel and at the cost and expense of the Company. 
 (b)
Subject to Sections 7.02(c) and 7.03 of this Third Supplemental Indenture, the Company at any time may terminate (1) all its obligations under the Securities and the Indenture (“legal defeasance option”) or (2) its obligations
under Sections 4.02, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13 and 4.14 of this Third Supplemental Indenture and the operation of Sections 6.02(4), 6.02(6), 6.02(7), 6.02(8), 6.02(9) and 6.02(10) of this Third Supplemental
Indenture (but, in the case of Sections 6.02 (7) and (8), with respect only to Significant Subsidiaries and Subsidiary Guarantors) and the limitations contained in Section 5.02(a)(3) of this Third Supplemental Indenture (“covenant
defeasance option”). The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. 

If the Company exercises its legal defeasance option, payment of the Securities may not be accelerated because of an Event of Default with
respect thereto. If the Company exercises its covenant defeasance option, payment of the Securities may not be accelerated because of an Event of Default specified in Sections 6.02(4), 6.02(5), 6.02(6), 6.02(7), 6.02(8), 6.02(9), 6.02(10) of this
Third Supplemental Indenture (but, in the case of Sections 6.02(7) and (8), with respect only to Significant Subsidiaries and Subsidiary Guarantors) or because of the failure of the Company to comply with Section 5.02(a)(3) of this Third
Supplemental Indenture. If the Company exercises its legal defeasance option or its covenant defeasance option, each Subsidiary Guarantor, if any, shall be released from all of its obligations with respect to its Subsidiary Guaranty. 

Upon satisfaction of the conditions set forth herein and upon request of the Company, the Trustee shall acknowledge in writing the discharge
of those obligations that the Company terminates. 
 (c) Notwithstanding clauses (a) and (b) above, the Company’s obligations
in Sections 305, 306, 307, 607 and 610 of the Original Indenture and in this Article 7 shall survive until the Securities have been paid in full. Thereafter, the Company’s obligations in Sections 607 of the Original Indenture, 7.04 and 7.05 of
this Third Supplemental Indenture shall survive. 
 SECTION 7.03. Conditions to Defeasance. The Company may exercise its legal
defeasance option or its covenant defeasance option only if: 
 (1) the Company irrevocably deposits in trust with the
Trustee money or U.S. Government Obligations for the payment of principal of and interest on the Securities to maturity or redemption, as the case may be; 

(2) the Company delivers to the Trustee a certificate from a nationally recognized investment bank, appraisal firm or a
nationally recognized firm of independent accountants expressing their opinion that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment
will provide cash at such times and in such amounts as will be sufficient to pay principal and interest when due on all the Securities to maturity or redemption, as the case may be; 

(3) 123 days pass after the deposit is made and during the 123-day period, no Default specified in Sections 6.02(7) or
(8) of this Third Supplemental Indenture with respect to the Company occurs which is continuing at the end of the period; 

  
 66 








 (4) the deposit does not constitute a default under any other agreement binding
on the Company and is not prohibited by Article 9; 
 (5) the Company delivers to the Trustee an Opinion of Counsel to the
effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940; 

(6) in the case of the legal defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel stating
that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (B) since the date of this Third Supplemental Indenture there has been a change in the applicable federal income tax law, in
either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Securityholders will not recognize income, gain or loss for Federal income tax purposes as a result of such 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 defeasance had not occurred; 

(7) in the case of the covenant defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel to
the effect that the Securityholders 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; and 
 (8) the Company delivers to the
Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Securities as contemplated by this Article 7 have been complied with. 

Before or after a deposit, the Company may make arrangements satisfactory to the Trustee for the redemption of Securities at a future date in
accordance with Article 3. 
 SECTION 7.04. Application of Trust Money. The Trustee shall hold in trust money or U.S. Government
Obligations deposited with it pursuant to this Article 7. It shall apply the deposited money and the money from U.S. Government Obligations through the Paying Agent and in accordance with the Indenture to the payment of principal of and interest on
the Securities. 
 SECTION 7.05. Repayment to Company. The Trustee and the Paying Agent shall promptly turn over to the Company upon
written request any excess money or securities held by them at any time. 
 Subject to any applicable abandoned property law, the Trustee
and the Paying Agent shall pay to the Company upon written request any money held by them for the payment of principal or interest that remains unclaimed for two years, and, thereafter, Securityholders entitled to the money must look to the Company
for payment as general creditors. 
 SECTION 7.06. Indemnity for Government Obligations. The Company shall pay and shall indemnify
the Trustee against any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations. 

SECTION 7.07. Reinstatement. If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance
with this Article 7 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or 

  
 67 








 
otherwise prohibiting such application, the Company’s obligations under the Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to this
Article 7 until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article 7; provided, however, that, if the Company has made any payment of interest on or
principal of any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the Trustee or
Paying Agent. 
 ARTICLE 8 

Amendments and Waivers 

SECTION 8.01. Original Indenture. Article IX of the Original Indenture shall not apply to the Securities and hereafter shall be void
and of no force and effect. 
 SECTION 8.02. Without Consent of Holders. The Company, the Subsidiary Guarantors and the Trustee may
amend this Third Supplemental Indenture or the Securities without notice to or consent of any Securityholder: 
 (1) to cure
any ambiguity, omission, defect or inconsistency; 
 (2) to provide for the assumption by a successor entity of the
obligations of the Company or any Subsidiary Guaranty in compliance with Article 5 hereof; 
 (3) to provide for
uncertificated Securities in addition to or in place of certificated Securities; provided, however, that the uncertificated Securities are issued in registered form for purposes of Section 163(f) of the Code; 

(4) to add Guarantees with respect to the Securities, including any Subsidiary Guaranties, or to evidence the release of any
Subsidiary Guarantor from its Subsidiary Guaranty as provided in this Third Supplemental Indenture; 
 (5) to secure the
Securities or the Subsidiary Guaranties, including pursuant to the requirements of Section 4.12 of this Third Supplemental Indenture; 

(6) to add to the covenants of the Company or a Subsidiary Guarantor for the benefit of the Holders or to surrender any right
or power herein conferred upon the Company or a Subsidiary Guarantor; 
 (7) to make any change that does not adversely
affect the rights of any Securityholder; 
 (8) to conform the text of this Third Supplemental Indenture, the Securities or
the Guarantees to any provision of the section entitled “Description of the notes” in the Prospectus Supplement to the extent that such provision in such section was intended to be a verbatim recitation of a provision of this Third
Supplemental Indenture, the Securities or the Guaranties (such conformation to be evidenced in an Officer’s Certificate); 

(9) to comply with any requirement of the SEC in connection with qualifying, or maintaining the qualification of, the
Indenture under the Trust Indenture Act; 

  
 68 








 (10) evidence and provide for the acceptance of an appointment under the
Indenture of a successor trustee; provided that the successor trustee is otherwise qualified and eligible to act as such under the terms of the Indenture; or 

(11) to make any amendment to the provisions of this Third Supplemental Indenture relating to the form, authentication,
transfer and legending of Securities; provided, however, that (a) compliance with this Third Supplemental Indenture as so amended would not result in Securities being transferred in violation of the Securities Act or any other applicable
securities law and (b) such amendment does not materially adversely affect the rights of Holders with respect to transfer of the Securities. 

After an amendment under this Section 8.02 becomes effective, the Company shall mail or otherwise deliver in accordance with the
procedures of DTC to Securityholders a notice briefly describing such amendment. The failure to give such notice to all Securityholders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 8.02.

 SECTION 8.03. With Consent of Holders. The Company, the Subsidiary Guarantors and the Trustee may amend this Third Supplemental
Indenture or the Securities with the written consent of the Holders of at least a majority in principal amount of the Securities then outstanding (including consents obtained in connection with a tender offer or exchange offer for the Securities)
and any past default or non-compliance with any provisions may also be waived with the consent of the Holders of at least a majority in principal amount of the Securities outstanding. However, without the consent of each Securityholder affected
thereby, an amendment or waiver may not: 
 (1) reduce the amount of Securities whose Holders must consent to an amendment;

 (2) reduce the rate of or extend the time for payment of interest on any Security; 

(3) reduce the principal of or change the Stated Maturity of any Security; 

(4) change the provisions applicable to the redemption of any Security contained in Article 3 or Section 3.02 of
this Third Supplemental Indenture; 
 (5) make any Security payable in money other than that stated in the Security;

this Section 8.03 of this Third Supplemental Indenture; 
 (8) make any change in the ranking or priority of any
Security that would adversely affect the Securityholders; or 
 (9) release, other than in accordance with this Third
Supplemental Indenture, any Subsidiary Guaranty that would adversely affect the Securityholders. 

  
 69 








 It shall not be necessary for the consent of the Holders under this Section 8.03 to approve
the particular form of any proposed amendment, waiver or consent but it shall be sufficient if such consent approves the substance thereof. 

After an amendment under this Section 8.03 becomes effective, the Company shall mail or otherwise deliver in accordance with the
procedures of DTC to Securityholders a notice briefly describing such amendment. The failure to give such notice to all Securityholders, or any defect therein, shall not impair or affect the validity of an amendment under this Section. 

SECTION 8.04. Compliance with Trust Indenture Act. Every amendment to this Third Supplemental Indenture or the Securities shall comply
with the Trust Indenture Act as then in effect. 
 SECTION 8.05. Revocation and Effect of Consents and Waivers. A consent to an
amendment or a waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent or
waiver is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date the
amendment or waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every Securityholder. An amendment or waiver becomes effective upon the execution of such amendment or waiver by the Trustee. 

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Securityholders entitled to give their
consent or take any other action described above or required or permitted to be taken pursuant to this Third Supplemental Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were
Securityholders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be
Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date. 
 SECTION 8.06.
Notation on or Exchange of Securities. If an amendment changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security regarding
the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms.
Failure to make the appropriate notation or to issue a new Security shall not affect the validity of such amendment. 
 SECTION 8.07.
Trustee To Sign Amendments. The Trustee shall sign any amendment authorized pursuant to this Article 8 if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but
need not sign it. In signing such amendment the Trustee shall be entitled to receive indemnity reasonably satisfactory to it and to receive, and (subject to Section 601 of the Original Indenture) shall be fully protected in relying upon, an
Officer’s Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by the Indenture and that such amendment is the legal, valid and binding obligation of the Company enforceable against it in accordance with
its terms, subject to customary exceptions, and complies with the provisions hereof (including Section 8.04 of this Third Supplemental Indenture). 

SECTION 8.08. Payment for Consent. Neither the Company nor any Affiliate of the Company shall, directly or indirectly, pay or cause to
be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Third Supplemental Indenture or the Securities unless such
consideration is offered to be paid to all Holders that so consent, waive or agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or agreement.

 ARTICLE 9 

Subsidiary Guaranties 

SECTION 9.01. Guaranties. Each Subsidiary Guarantor hereby unconditionally and irrevocably guarantees, jointly and severally, to each
Holder and to the Trustee and its successors and assigns (a) the full payment of principal of and interest on the Securities when due, whether at maturity, by acceleration, by redemption or otherwise, and all other monetary obligations of the
Company under this Third Supplemental Indenture and the Securities and (b) the full performance within applicable grace periods of all other obligations of the Company under this Third Supplemental Indenture and the Securities (all the
foregoing being hereinafter collectively called the “Guaranteed Obligations”). Each Subsidiary Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from
such Subsidiary Guarantor and that such Subsidiary Guarantor will remain bound under this Article 9 notwithstanding any extension or renewal of any Guaranteed Obligation. 

Each Subsidiary Guarantor waives presentation to, demand of, payment from and protest to the Company of any of the Guaranteed Obligations and
also waives notice of protest for nonpayment. Each Subsidiary Guarantor waives notice of any default under the Securities or the Guaranteed Obligations. The obligations of each Subsidiary Guarantor hereunder shall not be affected by (1) the
failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person (including any Subsidiary Guarantor) under the Indenture, the Securities or any other agreement or
otherwise; (2) any extension or renewal of any thereof; (3) any rescission, waiver, amendment or modification of any of the terms or provisions of the Indenture, the Securities or any other agreement; (4) the release of any security
held by any Holder or the Trustee for the Guaranteed Obligations or any of them; (5) the failure of any Holder or the Trustee to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (6) except as set
forth in Section 9.06 of this Third Supplemental Indenture, any change in the ownership of such Subsidiary Guarantor. 
 Each
Subsidiary Guarantor further agrees that its Subsidiary Guaranty herein constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder
or the Trustee to any security held for payment of the Guaranteed Obligations. 
 Except as expressly set forth in Sections 7.02(b), 9.02
and 9.06 of this Third Supplemental Indenture, the obligations of each Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender,
alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Obligations or otherwise. Without limiting the
generality of the foregoing, the obligations of each Subsidiary Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under the
Indenture, the Securities or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do
any other act or thing which may or might in any manner or to any extent vary the risk of such Subsidiary Guarantor or would otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law or equity. 

  
 71 








 Each Subsidiary Guarantor further agrees that its Guarantee herein shall continue to be effective
or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization
of the Company or otherwise. 
 In furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee has
at law or in equity against any Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay the principal of or interest on any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by
redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, each Subsidiary Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders
or the Trustee an amount equal to the sum of (A) the unpaid amount of such Guaranteed Obligations, (B) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by law) and (C) all other
monetary Guaranteed Obligations of the Company to the Holders and the Trustee. 
 Each Subsidiary Guarantor further agrees that, as between
it, on the one hand, and the Holders and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations may be accelerated as provided in Article 6 for the purposes of such Subsidiary Guarantor’s Subsidiary Guaranty herein,
notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations, and (ii) in the event of any declaration of acceleration of such Obligations as provided in Article 6, such
Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by such Subsidiary Guarantor for the purposes of this Section. 

Each Subsidiary Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the
Trustee or any Holder in enforcing any rights under this Section. 
 SECTION 9.02. Limitation on Liability. Any term or provision of
the Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations by any Subsidiary Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering the Indenture, as it relates to
such Subsidiary Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. 

SECTION 9.03. Successors and Assigns. This Article 9 shall be binding upon each Subsidiary Guarantor and its successors and assigns and
shall enure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that party in the Indenture and
in the Securities shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of the Indenture. 

SECTION 9.04. No Waiver. Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power
or privilege under this Article 9 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the
Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 9 at law, in equity, by statute or otherwise. 

SECTION 9.05. Modification. No modification, amendment or waiver of any provision of this Article 9, nor the consent to any departure
by any Subsidiary Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which
given. No notice to or demand on any Subsidiary Guarantor in any case shall entitle such Subsidiary Guarantor to any other or further notice or demand in the same, similar or other circumstances. 

  
 72 








 SECTION 9.06. Release of Subsidiary Guarantor. A Subsidiary Guarantor will be released
from its obligations under this Article 9 (other than any obligation that may have arisen under Section 9.07 of this Third Supplemental Indenture): 

(1) upon the sale or other disposition (including by way of merger, consolidation or otherwise) of such Subsidiary Guarantor
or following which such Subsidiary Guarantor is no longer a Restricted Subsidiary; 
 (2) upon the sale or disposition of
all or substantially all the assets of such Subsidiary Guarantor; 
 (3) upon the designation of such Subsidiary Guarantor
as an Unrestricted Subsidiary in accordance with the terms of this Third Supplemental Indenture; 
 (4) at such time as such
Subsidiary Guarantor does not have any Indebtedness outstanding that would have required such Subsidiary Guarantor to enter into a Guaranty Agreement pursuant to Section 4.14 of this Third Supplemental Indenture and the Company provides an
Officer’s Certificate to the Trustee certifying that no such Indebtedness is outstanding and that the Company elects to have such Subsidiary Guarantor released from this Article 9; 

(5) upon defeasance of the Securities or discharge of this Third Supplemental Indenture pursuant to Article 7 of this Third
Supplemental Indenture; or 
 (6) upon the liquidation or dissolution of any Subsidiary Guarantor, provided no
Default or Event of Default has occurred and is continuing; 
 provided, however, that in the case of clauses (1) and (2) above,
(i) such sale or other disposition is made to a Person other than the Company or a Subsidiary of the Company, (ii) such sale or disposition is otherwise permitted by this Third Supplemental Indenture and (iii) the Company provides an
Officer’s Certificate to the Trustee to the effect that the Company will comply with its obligations under Section 4.07 of this Third Supplemental Indenture. 

At the request of the Company, the Trustee shall execute and deliver an appropriate instrument evidencing such release. 

SECTION 9.07. Contribution. Each Subsidiary Guarantor that makes a payment under its Subsidiary Guaranty shall be entitled upon payment
in full of all guarantied obligations under the Indenture to a contribution from each other Subsidiary Guarantor in an amount equal to such other Subsidiary Guarantor’s pro rata portion of such payment based on the respective net assets of all
the Subsidiary Guarantors at the time of such payment determined in accordance with GAAP. 
 ARTICLE 10 

Miscellaneous 
 SECTION
10.01. Communication by Holders with Other Holders. Securityholders may communicate pursuant to Trust Indenture Act § 312(b) with other Securityholders with respect to their rights under the Indenture or the Securities. The Company,
any Subsidiary Guarantor, the Trustee, the Registrar and anyone else shall have the protection of Trust Indenture Act § 312(c). 

  
 73 








 SECTION 10.02. When Securities Disregarded. In determining whether the Holders of the
required principal amount of Securities have concurred in any direction, waiver or consent, Securities owned by the Company or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the
Company shall be disregarded and deemed not to be outstanding, except that, for the purpose of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities which the Trustee knows are so
owned shall be so disregarded. Also, subject to the foregoing, only Securities outstanding at the time shall be considered in any such determination. 

SECTION 10.03. No Recourse Against Others. Section 114 of the Original Indenture shall not apply to the Securities and hereafter
shall be void and of no force and effect and any reference in the Original Indenture to Section 114 thereof shall be deemed to refer to this Section 10.03 of this Third Supplemental Indenture. No past, present or future director, officer,
employee, incorporator or stockholder, of the Company or any Subsidiary Guarantor will have any liability for any obligations of the Company or any Subsidiary Guarantor under the Securities, any Subsidiary Guaranty, 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 Security shall waive and releases all such liability. The waiver and release shall be part of the consideration for issuance of the Securities.

 SECTION 10.04. Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof. 
 SECTION 10.05. Successors and Assigns. All covenants and agreements
in the Indenture by the Company shall bind its successors and assigns, whether so expressed or not. All agreements of the Trustee in the Indenture shall bind its successors and assigns, whether so expressed or not. 

SECTION 10.06. Separability Clause. In case any provision in this Third Supplemental Indenture or in the Securities shall be invalid,
illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 

SECTION 10.07. Governing Law. This Third Supplemental Indenture and the Securities shall be governed by, and construed in accordance
with, the law of the State of New York. 
 SECTION 10.08. Rules by Trustee, Paying Agent and Registrar. The Trustee may make
reasonable rules for action by or a meeting of Securityholders. The Registrar and the Paying Agent may make reasonable rules for their functions. 

SECTION 10.09. No Adverse Interpretation of Other Agreements. This Third Supplemental indenture may not be used to interpret any other
indenture, loan or debt agreement of the Company or its Subsidiaries or of any other Person, other than the Original Indenture. Other than the Original Indenture, no such indenture, loan or debt agreement may be used to interpret this Third
Supplemental Indenture 
 SECTION 10.10. Multiple Originals. The parties may sign any number of copies of this Third Supplemental
Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. One signed copy is enough to prove this Third Supplemental Indenture.

		 		 		 	Authorized Signatory








 [FORM OF REVERSE SIDE OF SECURITY] 

8.500% Senior Note Due 2022 
  

	1.	Interest 

 EXCO Resources, Inc., a Texas corporation (such corporation, and its
successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Security at the rate per annum shown above. Interest on the Securities will
accrue from the most recent date to which interest has been paid or, if no interest has been paid, from April 16, 2014. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The Company will pay interest on overdue
principal at the rate borne by this Security plus 1.0% per annum, and it will pay interest on overdue installments of interest at the same rate to the extent lawful. 
  

	2.	Method of Payment 

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

	3.	Paying Agent and Registrar 

 Initially, Wilmington Trust Company, a Delaware trust
company (the “Trustee”), will act as Paying Agent and Security Registrar. The Company may appoint and change any Paying Agent, Security Registrar or co-registrar. The Company or any of its domestically incorporated Wholly Owned
Subsidiaries may act as Paying Agent, Security Registrar or co-registrar. 
  

	4.	Indenture 

 Third Supplemental Indenture dated as of April 16, 2014, (the “Third Supplemental
Indenture”) among the Company, the Subsidiary Guarantors and the Trustee from time to time party hereto and the Trustee, and the Company and the Trustee executed and delivered an Indenture, dated as of September 15, 2010 (the
“Original Indenture”, together with the Third Supplemental Indenture, the “Indenture”). The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture
Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “Act”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are
subject to all such terms, and Securityholders are referred to the Indenture and the Act for a statement of those terms. 
 The Securities
are senior unsecured obligations of the Company. The Company shall be entitled, subject to its compliance with Section 4.05 of the Third Supplemental Indenture, to issue Additional 







 
Securities pursuant to Section 1.01 of the Third Supplemental Indenture. The Securities issued on the Issue Date and any Additional Securities will be treated as a single class for all
purposes under the Indenture. The Indenture contains covenants that limit the ability of the Company and its subsidiaries to incur additional indebtedness; pay dividends or distributions on, or redeem or repurchase capital stock; make investments;
engage in transactions with affiliates; create liens on assets; transfer or sell assets; guarantee indebtedness; restrict dividends or other payments of subsidiaries; consolidate, merge or transfer all or substantially all of its assets and the
assets of its subsidiaries; and engage in sale/leaseback transactions. These covenants are subject to important exceptions and qualifications. 
  

	5.	Optional Redemption 

 The Company shall be entitled to redeem the Securities as set forth
in Section 3.02 of the Third Supplemental Indenture. 
  

	6.	[Reserved] 

  

	7.	Put Provisions 

 Upon a Change of Control, any Holder of Securities will have the right
to cause the Company to repurchase all or any part of the Securities of such Holder at a repurchase price in cash equal to 101% of the principal amount of the Securities to be repurchased plus accrued interest to the date of repurchase (subject to
the right of holders of record on the relevant record date to receive interest due on the related interest payment date) as provided in, and subject to the terms of, the Indenture. 

The Company may be required to make an offer to purchase Securities in the event of an Asset Disposition as set forth in Section 4.08 of
the Third Supplemental Indenture. 
  

	8.	Guaranty 

 The payment by the Company of the principal of, and premium (if any) and
interest on, the Securities is fully and unconditionally guaranteed on a joint and several senior basis by each of the Subsidiary Guarantors to the extent set forth in the Indenture. 

 

	9.	Denominations; Transfer; Exchange 

 The Securities are in registered form without coupons
in minimum denominations of $2,000 principal amount and whole multiples of $1,000. A Holder may transfer or exchange Securities in accordance with the Indenture. The Security Registrar may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Security Registrar need not register the transfer of or exchange any Securities selected for redemption (except, in the case of a
Security to be redeemed in part, the portion of the Security not to be redeemed) or any Securities for a period of 15 days before a selection of Securities to be redeemed or 15 days before an interest payment date. 

 

	10.	Persons Deemed Owners 

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








	11.	Unclaimed Money 

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

	12.	Discharge and Defeasance 

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

	13.	Amendment, Waiver 

 Subject to certain exceptions set forth in the Indenture,
(a) the Indenture and the Securities may be amended with the written consent of the Holders of at least a majority in principal amount outstanding of the Securities (including consents obtained in connection with a tender offer or exchange
offer for Securities) and (b) any past default or noncompliance with any provision may be waived with the written consent of the Holders of a majority in principal amount outstanding of the Securities. Subject to certain exceptions set forth in
the Indenture, without the consent of any Securityholder, the Company, the Subsidiary Guarantors and the Trustee shall be entitled to amend the Indenture or the Securities to cure any ambiguity, omission, defect or inconsistency, or to comply with
Article 5 of the Third Supplemental Indenture, or to provide for uncertificated Securities in addition to or in place of certificated Securities, or to add guarantees with respect to the Securities, including Subsidiary Guaranties, or to evidence
the release of any Subsidiary Guarantor as provided in the Third Supplemental Indenture or to secure the Securities or the Subsidiary Guaranties, or to add additional covenants of or surrender rights and powers conferred on the Company or the
Subsidiary Guarantors, or to conform the text of the Third Supplemental Indenture, the Securities or the Guarantees to any provision of the section entitled “Description of the notes” in the Prospectus Supplement dated April 11, 2014
in certain cases, or to comply with any requirement of the SEC in connection with qualifying or maintaining the qualifications of the Indenture under the Act, or to make any change that does not adversely affect the rights of any Securityholder, or
to make any amendment to the provisions of the Third Supplemental Indenture relating to the form, authentication, transfer and legending of Securities in certain cases. 
  

	14.	Defaults and Remedies 

 Under the Indenture, Events of Default include (a) default
for 30 days in payment of interest on the Securities; (b) default in payment of principal on the Securities at maturity, upon redemption pursuant to paragraph 5 of the Securities, upon acceleration or otherwise, or failure by the Company to
redeem or purchase Securities when required; (c) failure by the Company, or any Subsidiary Guarantor to comply with other agreements in the Indenture or the Securities, in certain cases subject to notice and lapse of time; (d) certain
accelerations (including failure to pay within any grace period after final maturity) of other Indebtedness of the Company if the amount accelerated (or so unpaid) exceeds $25.0 million; (e) certain events of bankruptcy or insolvency with
respect to the Company, a Subsidiary Guarantor or any Significant Subsidiaries; (f) certain judgments or decrees for the payment of money in excess of $25.0 million; and (g) certain defaults with respect to Subsidiary Guaranties. If an
Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Securities may declare all the Securities to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of
Default which will result in the Securities being due and payable immediately upon the occurrence of such Events of Default. 







 Securityholders may not enforce the Indenture or the Securities except as provided in the
Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the Securities may direct the
Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default (except a Default in payment of principal or interest) if and so long as it determines that withholding notice is in the
interest of the Holders. 
  

	15.	Trustee Dealings with the Company 

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

	16.	No Recourse Against Others 

 No past, present or future director, officer, employee,
incorporator or stockholder, of the Company or any Subsidiary Guarantor will have any liability for any obligations of the Company or any Subsidiary Guarantor under the Securities, any Subsidiary Guaranty, or the Indenture or for any claim based on,
in respect of, or by reason of such obligations or their creation. By accepting a Security, each Securityholder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities. 

 

	17.	Authentication 

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

	18.	Abbreviations 

 Customary abbreviations may be used in the name of a Securityholder or an
assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act). 

 

	19.	CUSIP Numbers 

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

WITH, THE LAWS OF THE STATE OF NEW YORK.
