 INDENTURE, dated as of June 20, 2005, among CHESAPEAKE ENERGY CORPORATION, an Oklahoma corporation (the
“Company”), the SUBSIDIARY GUARANTORS listed as signatories hereto and The Bank of New York Trust Company, N.A., a national banking association, as Trustee. 
  
 Each party agrees as follows for the benefit of the other parties and for the equal and ratable benefit of the holders of
the Company’s 6.25% Senior Notes due 2018: 
  
 ARTICLE ONE

  
 DEFINITIONS AND INCORPORATION BY REFERENCE 
  
 SECTION 1.01. Definitions. 
  
 “Additional Securities” means, subject to the Company’s
compliance with Section 4.09(a), 6.25% Senior Notes due 2018 issued from time to time after the Issue Date under the terms of this Indenture (other than pursuant to Section 2.06, 2.07, 2.09 or 3.06 of this Indenture and other than Exchange
Securities or Private Exchange Securities issued pursuant to an exchange offer for other Securities outstanding under this Indenture). 
  
 “Adjusted Consolidated EBITDA” means the Consolidated Net Income of the Company and its Restricted Subsidiaries for the Reference Period, (a)
increased (to the extent deducted in determining Consolidated Net Income) by the sum, without duplication, of: (i) all income and state franchise taxes of the Company and its Restricted Subsidiaries paid or accrued according to GAAP for such period
(other than income taxes attributable to extraordinary, unusual or non-recurring gains or losses); (ii) all interest expense of the Company and its Restricted Subsidiaries paid or accrued in accordance with GAAP for such period (including
amortization of original issue discount or premium); (iii) depreciation and depletion of the Company and its Restricted Subsidiaries; (iv) amortization of the Company and its Restricted Subsidiaries including, without limitation, amortization of
capitalized debt issuance costs; (v) any loss realized in accordance with GAAP upon the sale or other disposition of any property, plant or equipment of the Company or its Restricted Subsidiaries (including pursuant to any Sale/Leaseback
Transaction) which is not sold or otherwise disposed of in the ordinary course of business and any loss realized in accordance with GAAP upon the sale or other disposition of any Capital Stock of any Person; (vi) any loss realized in accordance with
GAAP from currency exchange transactions not in the ordinary course of business consistent with past practice; (vii) any loss net of income taxes realized in accordance with GAAP attributable to extraordinary items; (viii) any charges associated
with the repurchase, prepayment or retirement of any Indebtedness including, without limitation, charges related to any premium or penalty paid or the write-off of deferred financing charges; and (ix) any other non-cash charges to the extent
deducted from Consolidated Net Income and (b) decreased (to the extent included in determining Consolidated Net Income) by the sum of (i) the amount of deferred revenues that are amortized during the Reference Period and are attributable to reserves
that are subject to Volumetric Production Payments and (ii) amounts recorded in accordance with GAAP as repayments of principal and interest pursuant to Dollar-Denominated Production Payments. 
  
 “Adjusted Consolidated EBITDA Coverage Ratio” means, for any
Reference Period, the ratio on a pro forma basis of (a) Adjusted Consolidated EBITDA for the Reference Period to (b) Adjusted Consolidated Interest Expense 

 
for such Reference Period; provided, that, in calculating Adjusted Consolidated EBITDA and Adjusted Consolidated Interest Expense (i) acquisitions
which occurred during the Reference Period or subsequent to the Reference Period and on or prior to the date of the transaction giving rise to the need to calculate the Adjusted Consolidated EBITDA Coverage Ratio (the “Transaction Date”)
will be given pro forma effect as if they had occurred on the first day of the Reference Period, including any Adjusted Consolidated EBITDA and any pro forma expense and cost reductions that have occurred or are reasonably expected to occur, in the
reasonable judgment of the chief financial or accounting officer of the Company regardless of whether those cost savings or operating improvements could then be reflected in pro forma financial statements in accordance with Regulation S-X
promulgated under the Securities Act or any other regulation or policy of the SEC related thereto, (ii) the incurrence of any Indebtedness (including the issuance of the Securities) or issuance of any Disqualified Stock during the Reference Period
or subsequent to the Reference Period and on or prior to the Transaction Date shall be assumed to have occurred on the first day of such Reference Period, (iii) any Indebtedness that had been outstanding during the Reference Period that has been
repaid on or prior to the Transaction Date shall be assumed to have been repaid as of the first day of such Reference Period, (iv) the Adjusted Consolidated Interest Expense attributable to interest on any Indebtedness or dividends on any
Disqualified Stock bearing a floating interest (or dividend) rate shall be computed on a pro forma basis as if the rate in effect on the Transaction Date were the average rate in effect during the entire Reference Period and (v) in determining the
amount of Indebtedness pursuant to Section 4.09, the incurrence of Indebtedness or issuance of Disqualified Stock giving rise to the need to calculate the Adjusted Consolidated EBITDA Coverage Ratio and, to the extent the net proceeds from the
incurrence or issuance thereof are used to retire Indebtedness, the application of the proceeds therefrom shall be assumed to have occurred on the first day of the Reference Period. 
  
 “Adjusted Consolidated Interest Expense” means, with respect to the Company and its Restricted Subsidiaries, for
the Reference Period, the aggregate amount (without duplication) of (a) interest expensed in accordance with GAAP (including, in accordance with the following sentence, interest attributable to Capitalized Lease Obligations, but excluding interest
attributable to Dollar-Denominated Production Payments and amortization of deferred debt expense) during such period in respect of all Indebtedness of the Company and its Restricted Subsidiaries (including (i) amortization of original issue discount
or premium on any Indebtedness (other than with respect to the Existing Notes and the Securities), (ii) the interest portion of all deferred payment obligations, calculated in accordance with GAAP, and (iii) all commissions, discounts and other fees
and charges owed with respect to bankers’ acceptance financings and currency and interest rate swap arrangements, in each case to the extent attributable to such period), and (b) dividend requirements of the Company and its Restricted
Subsidiaries with respect to any Preferred Stock dividends (whether in cash or otherwise (except dividends paid solely in shares of Qualified Stock)) paid (other than to the Company or any of its Restricted Subsidiaries), declared, accrued or
accumulated during such period, in each case to the extent attributable to such period and excluding items eliminated in consolidation. For purposes of this definition, (a) interest on a Capitalized Lease Obligation shall be deemed to accrue at an
interest rate reasonably determined by the Company to be the rate of interest implicit in such Capitalized Lease Obligation in accordance with GAAP and (b) interest expense attributable to any Indebtedness represented by the guarantee by the Company
or a Restricted Subsidiary of the Company of an obligation of another Person shall be deemed to be the interest expense attributable to the Indebtedness guaranteed.

 “Adjusted Consolidated Net Tangible Assets” or “ACNTA” means (without duplication),
as of the date of determination, (a) the sum of (i) discounted future net revenue from proved oil and gas reserves of the Company and its Restricted Subsidiaries calculated in accordance with SEC guidelines before any state or federal income taxes,
as estimated by petroleum engineers (which may include the Company’s internal engineers) in a reserve report prepared as of the end of the Company’s most recently completed fiscal year, as increased by, as of the date of determination, the
discounted future net revenue of (A) estimated proved oil and gas reserves of the Company and its Restricted Subsidiaries attributable to any acquisition consummated since the date of such year-end reserve report, and (B) estimated proved oil and
gas reserves of the Company and its Restricted Subsidiaries attributable to extensions, discoveries and other additions and upward revisions of estimates of proved oil and gas reserves due to exploration, development or exploitation, production or
other activities conducted or otherwise occurring since the date of such year-end reserve report, which, in the case of sub-clauses (A) and (B), would, in accordance with standard industry practice, result in such increases as calculated in
accordance with SEC guidelines (utilizing the prices utilized in such year-end reserve report), and decreased by, as of the date of determination, the discounted future net revenue of (C) estimated proved oil and gas reserves of the Company and its
Restricted Subsidiaries produced or disposed of since the date of such year-end reserve report and (D) reductions in the estimated oil and gas reserves of the Company and its Restricted Subsidiaries since the date of such year-end reserve report
attributable to downward revisions of estimates of proved oil and gas reserves due to exploration, development or exploitation, production or other activities conducted or otherwise occurring since the date of such year-end reserve report which, in
the case of sub-clauses (C) and (D), would, in accordance with standard industry practice, result in such decreases as calculated in accordance with SEC guidelines (utilizing the prices utilized in such year-end reserve report); provided
that, in the case of each of the determinations made pursuant to clauses (A) through (D), such increases and decreases shall be as estimated by the Company’s engineers, (ii) the capitalized costs that are attributable to oil and gas properties
of the Company and its Restricted Subsidiaries to which no proved oil and gas reserves are attributable, based on the Company’s books and records as of a date no earlier than the date of the Company’s latest annual or quarterly financial
statements, (iii) the Net Working Capital on a date no earlier than the date of the Company’s latest annual or quarterly financial statements and (iv) the greater of (I) the net book value on a date no earlier than the date of the
Company’s latest annual or quarterly financial statements and (II) the appraised value, as estimated by independent appraisers, of other tangible assets (including Investments in unconsolidated Subsidiaries) of the Company and its Restricted
Subsidiaries, as of a date no earlier than the date of the Company’s latest audited financial statements, minus (b) the sum of (i) minority interests, (ii) any gas balancing liabilities of the Company and its Restricted Subsidiaries reflected
as a long-term liability in the Company’s latest annual or quarterly financial statements, (iii) the discounted future net revenue, calculated in accordance with SEC guidelines (utilizing the prices utilized in the Company’s year-end
reserve report), attributable to reserves which are required to be delivered to third parties to fully satisfy the obligations of the Company and its Restricted Subsidiaries with respect to Volumetric Production Payments on the schedules specified
with respect thereto, (iv) the 

  

 3 

 
discounted future net revenue, calculated in accordance with SEC guidelines, attributable to reserves subject to Dollar-Denominated Production Payments
which, based on the estimates of production included in determining the discounted future net revenue specified in (a) (i) above (utilizing the same prices utilized in the Company’s year-end reserve report), would be necessary to fully satisfy
the payment obligations of the Company and its Restricted Subsidiaries with respect to Dollar-Denominated Production Payments on the schedules specified with respect thereto and (v) the discounted future net revenue, calculated in accordance with
SEC guidelines (utilizing the same prices utilized in the Company’s year-end reserve report), 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. If the Company changes its method of accounting from the full cost method to the successful efforts
method or a similar method of accounting, Adjusted Consolidated Net Tangible Assets will continue to be calculated as if the Company were still using the full cost method of accounting. 
  
 “Adjusted Net Assets of a Subsidiary Guarantor” at any date shall mean the lesser of (i) the amount by which the
fair value of the property of such Subsidiary Guarantor exceeds the total amount of liabilities, including, without limitation, contingent liabilities (after giving effect to all other fixed and contingent liabilities incurred or assumed on such
date), but excluding liabilities under the Guarantee of such Subsidiary Guarantor at such date and (ii) the amount by which the present fair saleable value of the assets of such Subsidiary Guarantor at such date exceeds the amount that will be
required to pay the probable liability of such Subsidiary Guarantor on its debts (after giving effect to all other fixed and contingent liabilities incurred or assumed on such date and after giving effect to any collection from any Subsidiary of
such Subsidiary Guarantor in respect of the obligations of such Subsidiary under the Guarantee), excluding debt in respect of the Guarantee, as they become absolute and matured. 
  
 “Affiliate” of any specified Person means any other Person directly or indirectly controlling or controlled by or
under direct or indirect common control with such specified Person. For the purposes of this definition, “control” when used with respect to any specified Person means the power to direct the management and policies of such Person directly
or indirectly, whether through the ownership of Voting Stock, by contract or otherwise; and the terms “controlling” and “controlled” have meanings correlative to the foregoing. 
  
 “Agent” means any Registrar, Paying Agent or co-registrar.

  
 “Asset Sale” means any sale, lease, transfer,
exchange or other disposition (or series of related sales, leases, transfers, exchanges or dispositions) having a fair market value of $5,000,000 or more of shares of Capital Stock of a Restricted Subsidiary (other than directors’ qualifying

connection with the financing of, and within 30 days after, the acquisition of the properties subject thereto) or any interests therein (each referred to for purposes of this definition as a “disposition”) by the Company or any of its
Restricted Subsidiaries, including any disposition by means of a merger, consolidation or similar

transaction (other than (a) by the Company to a Restricted Subsidiary or by a Restricted Subsidiary to the Company or another Restricted Subsidiary, (b) a
sale of oil, gas or other hydrocarbons or other mineral products in the ordinary course of business of the Company’s oil and gas production operations, (c) any abandonment, farm-in, farm-out, lease and sub-lease of developed and/or undeveloped
properties made or entered into in the ordinary course of business, but excluding (x) any sale of a net profits or overriding royalty interest, in each case conveyed from or burdening proved developed or proved undeveloped reserves and (y) any sale
of hydrocarbons or other mineral products as a result of the creation of Dollar-Denominated Production Payments or Volumetric Production Payments, other than Dollar-Denominated Production Payments and Volumetric Production Payments created or sold
in connection with the financing of, and within 30 days after, the acquisition of the properties subject thereto), (d) the disposition of all or substantially all of the assets of the Company in compliance with Article Five, (e) Sale/Leaseback
Transactions in compliance with Section 4.13, (f) the provision of services and equipment for the operation and development of the Company’s oil and gas wells, in the ordinary course of the Company’s oil and gas service businesses,
notwithstanding that such transactions may be recorded as asset sales in accordance with full cost accounting guidelines, and (g) the issuance by the Company of shares of its Capital Stock). 
  
 “Attributable Indebtedness” means, with respect to any particular
lease under which any Person is at the time liable and at any date as of which the amount thereof is to be determined, the present value of the total net amount of rent required to be paid by such Person under the lease during the primary term
thereof, without giving effect to any renewals at the option of the lessee, discounted from the respective due dates thereof to such date at the rate of interest per annum implicit in the terms of the lease. As used in the preceding sentence, the
“net amount of rent” under any lease for any such period shall mean the sum of rental and other payments required to be paid with respect to such period by the lessee thereunder excluding any amounts required to be paid by such lessee on
account of maintenance and repairs, insurance, taxes, assessments, water rates or similar charges. In the case of any lease which is terminable by the lessee upon payment of a penalty, such net amount of rent shall also include the amount of such
penalty, but no rent shall be considered as required to be paid under such lease subsequent to the first date upon which it may be so terminated. 
  
 “Average Life” means, as of the date of determination, with respect to any Indebtedness, the quotient obtained by dividing (i) the product of

 THE SECURITIES 
  
 SECTION 2.01. Form and Dating. Provisions relating to the Initial
Securities, the Private Exchange Securities and the Exchange Securities are set forth in the Rule 144A/Regulation S Appendix attached hereto (the “Appendix”) which is hereby incorporated in and expressly made part of this Indenture. The
Initial Securities and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit 1 to the Appendix which is hereby incorporated in and expressly made a part of this Indenture. The Exchange Securities, the Private
Exchange Securities and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A, which is hereby incorporated in and expressly made a part of this Indenture. The Securities may have notations, legends or
endorsements required by law, stock exchange rule, agreements to which the Company is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company and to the Trustee). Each Security
shall be dated the date of its authentication. The terms of the Securities set forth in the Appendix and Exhibit A are part of the terms of this Indenture. 
  
 SECTION 2.02. Execution and Authentication. Two Officers shall sign the Securities for the Company by manual or facsimile signature. 
  

 21 

 If an Officer whose signature is on a Security no longer holds that office at the time the Trustee
authenticates the Security, the Security shall be valid nevertheless. 
  
 A Security shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this
Indenture. 
  
 On the Issue Date, the Trustee shall authenticate
and deliver $600 million of Initial Securities and, at any time and from time to time thereafter, the Trustee shall authenticate and deliver Securities for original issue in an aggregate principal amount specified in such order, in each case upon a
written order of the Company signed by two Officers or by an Officer and either an Assistant Treasurer or an Assistant Secretary of the Company. Such order shall specify the amount of the Securities to be authenticated and the date on which the
original issue of Securities is to be authenticated and, in the case of an issuance of Additional Securities pursuant to Section 2.13 after the Issue Date, shall certify that such issuance is in compliance with Section 4.09. 
  
 The Trustee may appoint an authenticating agent reasonably acceptable to the
Company to authenticate the Securities. Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes
authentication by such agent. An authenticating agent has the same rights with respect to the Company as any Registrar, Paying Agent or agent for service of notices and demands. 
  
 SECTION 2.03. Registrar and Paying Agent. The Company shall maintain an office or agency where Securities may be
presented for registration of transfer or for exchange (the “Registrar”) and an office or agency where Securities may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Securities and of
their transfer and exchange. The Company may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent. 
  
 The Company shall enter into an appropriate agency agreement with any
Registrar, Paying Agent or co-registrar not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of
the name and address of any such agent and shall furnish the Trustee with an executed counterpart of any such agency agreement. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to
appropriate compensation therefor pursuant to Section 7.07. The Company or any wholly owned Subsidiary incorporated or organized within The United States of America may act as Paying Agent, Registrar, co-registrar or transfer agent. 
  
 The Company initially appoints the Trustee as Registrar and Paying Agent in
connection with the Securities. 
  
 SECTION 2.04. Paying Agent
To Hold Money in Trust. Prior to 11:00 a.m., New York time, each due date of the principal and interest on any Security, the Company shall deposit with the Paying Agent a sum sufficient to pay such principal and interest when so becoming due.
The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying 

  

 22 

 
Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of or interest on the
Securities and shall notify the Trustee of any default by the Company in making any such payment. If the Company or a Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The
Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent shall have no further liability for the money
delivered to the Trustee. 
  
 SECTION 2.05. Holder Lists.
The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee, in writing at
least five Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders.

  
 SECTION 2.06. Transfer and Exchange. The Securities
shall be issued in registered form and shall be transferable only upon the surrender of a Security for registration of transfer. When a Security is presented to the Registrar or a co-registrar with a request to register a transfer, the Registrar
shall register the transfer as requested if the requirements of this Indenture and Section 8-401(a) of the Uniform Commercial Code are met. When Securities are presented to the Registrar or a co-registrar with a request to exchange them for an equal
principal amount of Securities of other denominations, the Registrar shall make the exchange as requested if the same requirements are met. 
  
 SECTION 2.07. Replacement Securities. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the
Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security if the requirements of Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies any other
reasonable requirements of the Trustee. If required by the Trustee or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of the Company and the Trustee to protect the Company, the Trustee, the Paying Agent, the
Registrar and any co-registrar from any loss which any of them may suffer if a Security is replaced. The Company and the Trustee may charge the Holder for their expenses in replacing a Security. 
  
 Every replacement Security is an additional obligation of the Company.

  
 SECTION 2.08. Outstanding Securities. Securities
outstanding at any time are all Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancelation and those described in this Section as not outstanding. A Security does not cease to be outstanding
because the Company or an Affiliate of the Company holds the Security. 
  
 If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a bona fide purchaser. 
  
 If the Paying Agent segregates and holds in trust, in accordance with this
Indenture, on a redemption date or maturity date money sufficient 

  

 23 

 
to pay all principal and interest payable on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case may be,
then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue. 
  
 SECTION 2.09. Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate
temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and
the Trustee shall authenticate definitive Securities and deliver them in exchange for temporary Securities. 
  
 SECTION 2.10. Cancelation. The Company at any time may deliver Securities to the Trustee for cancelation. The Registrar and the Paying Agent shall
forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel and dispose of (subject to the record retention requirements of the Exchange Act) all Securities
surrendered for registration of transfer, exchange, payment or cancelation in its customary manner and upon request shall deliver a certificate of such disposal to the Company unless the Company directs the Trustee to deliver canceled Securities to
the Company. The Company may not issue new Securities to replace Securities it has redeemed, paid or delivered to the Trustee for cancelation. 
  
 SECTION 2.11. Defaulted Interest. If the Company defaults in a payment of interest on the Securities, the Company shall pay defaulted interest
(plus interest on such defaulted interest to the extent lawful) in any lawful manner. The Company may pay the defaulted interest to the persons who are Holders on a subsequent special record date. The Company shall fix or cause to be fixed any such
special record date and payment date to the reasonable satisfaction of the Trustee and shall promptly mail to each Holder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid. 
  
 SECTION 2.12. CUSIP Numbers. The Company in issuing the Securities may
use “CUSIP” numbers (if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no
representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and
any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall notify the Trustee of any change in the CUSIP numbers. 
  

SECTION 2.13. Issuance of Additional Securities. The Company shall be entitled, subject to its compliance with Section 4.09(a), to issue
Additional Securities under this Indenture which shall have identical terms as the Initial Securities issued on the Issue Date, other than with respect to the date of issuance and issue price. The Initial Securities issued on the Issue Date, any
Additional Securities and all Exchange Securities or Private Exchange Securities issued in exchange therefor shall be treated as a single class for all purposes under this Indenture. 
  

 24 

 With respect to any Additional Securities, the Company shall set forth in a resolution of the Board of
Directors and an Officers’ Certificate, a copy of each which shall be delivered to the Trustee, the following information: 
  
 (1) the aggregate principal amount of such Additional Securities to be authenticated and delivered pursuant to this Indenture; 

 
 (2) the issue price, the issue date and the CUSIP number
of such Additional Securities; provided, however, that no Additional Securities may be issued at a price that would cause such Additional Securities to have “original issue discount” within the meaning of Section 1273 of the
Code; and 
  
 (3) whether such Additional
Securities shall be Transfer Restricted Securities and issued in the form of Initial Securities as set forth in the Appendix to this Indenture or shall be issued in the form of Exchange Securities as set forth in Exhibit A. 
  
 Additional Securities may be issued with the same CUSIP number as the
Securities issued on the Issue Date if, and only if, the Company shall have provided the Trustee with an opinion of nationally recognized counsel, reasonably satisfactory to the Trustee, to the effect that such Additional Securities will be fungible
with the Securities issued on the Issue Date for all United States federal income tax purposes. 
  
 ARTICLE THREE

 (7) if any Security is being redeemed in part, the portion
of the principal amount of such Security to be redeemed and that, after the redemption date, upon surrender of such Security, a new Security or Securities in principal amount equal to the unredeemed portion will be issued in the name of the Holder
thereof upon cancelation of the Security or Securities being redeemed; 
  
 (8) the paragraph of the Securities pursuant to which the Securities called for redemption are being redeemed; and 
  
 (9) the CUSIP number of the Securities. 
  
 (b) At the Company’s request, the Trustee shall give the notice of redemption required in Section 3.03(a) in the Company’s name and at the
Company’s expense; provided, however, that the Company shall deliver to the Trustee, at least 45 days prior to the redemption date (unless the Trustee consents to a shorter notice period in writing), an Officers’ Certificate
requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in Section 3.03(a). 
  
 SECTION 3.04. Effect of Notice of Redemption. Once notice of redemption is mailed in accordance with Section 3.03, Securities called for redemption
become due and payable on the redemption date at the redemption price. Upon surrender to the Paying Agent, such Securities shall be paid at the redemption price, plus accrued and unpaid interest to the redemption date (subject to the right of
Holders of record on the relevant record date to receive interest due on the related interest payment date). Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder.

 SECTION 3.05. Deposit of Redemption Price. Prior to 11:00 a.m., New York time, the redemption
date, the Company shall deposit with the Paying Agent (or if the Company or a Subsidiary is the Paying Agent, shall segregate and hold in trust) funds available on the redemption date sufficient to pay the redemption price of, and accrued and unpaid
interest on, the Securities to be redeemed on that date. The Paying Agent shall promptly return to the Company any money so deposited which is not required for that purpose upon the written request of the Company, except with respect to monies owed
as obligations to the Trustee pursuant to Article Seven. 
  
 If
any Security called for redemption shall not be so paid upon redemption because of the failure of the Company to comply with the preceding paragraph, interest will continue to be payable on the unpaid principal and premium, if any, including from
the redemption date until such principal and premium, if any, is paid, and, to the extent lawful, on any interest not paid on such unpaid principal, in each case at the rate provided in the Securities and in Section 4.01 hereof. 
  
 SECTION 3.06. Securities Redeemed in Part. Upon surrender of a
Security that is to be redeemed in part, the Company shall issue and the Trustee shall authenticate for the Holder, at the expense of the Company, a new Security equal in aggregate amount to the unredeemed portion of the Security surrendered.

  
 SECTION 3.07. Optional Redemption. Except as set forth

Offering or Equity Offerings at a redemption price of 106.25% of the aggregate principal amount of the Securities so redeemed, plus accrued and unpaid interest on the Securities so redeemed to the redemption date; provided, however,
that (i) the date of any such redemption occurs within the 120-day period after the Equity Offering in respect of which such redemption is made and (ii) following each such redemption, at least 65% of the aggregate principal amount of the Securities

 SECTION 4.01. Payment of Securities. The Company shall pay the principal of, premium, if any, and interest on, the Securities on the dates and in the manner provided in the Securities and this Indenture. Principal, premium and
interest shall be considered paid on the date due if the Trustee or Paying Agent holds on that date money deposited by the Company designated for and sufficient to pay all principal, premium and interest then due. All references to interest in this
Indenture shall for all purposes be deemed to include any additional interest payable as liquidated damages pursuant to the Registration Rights Agreement.

(a) The Company, within 15 days after it files the same with the SEC, shall deliver to Holders, copies of the annual reports and the information, documents and other reports (or copies of any such portions of any of the foregoing as the SEC may

 SECTION 4.03. Compliance Certificates. (a) The Company shall deliver to the Trustee, within 90
days after the end of each fiscal year of the Company, an Officers’ Certificate substantially in the form of Exhibit J hereto, stating that a review of the activities of the Company and the Subsidiaries during the preceding fiscal year has been
made under the supervision of the signing Officers with a view to determining whether the Company has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such
certificate, that, to the best of such Officer’s knowledge, the Company and each Subsidiary Guarantor has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or
observance of any of the terms, provisions and conditions hereof (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which such Officer may have knowledge and what action the Company is
taking or proposes to take with respect thereto) and that to the best of such Officer’s knowledge, after reasonable inquiry, no event has occurred and remains in existence by reason of which payments on account of the principal of, premium, if
any, or interest, if any, on the Securities are prohibited or, if such event has occurred, a description of the event and what action the Company and the Subsidiary Guarantors are taking or propose to take with respect thereto. Such Officers’
Certificate shall comply with TIA Section 314(a)(4). The Company hereby represents that, as of the Issue Date, its fiscal year ends December 31, and hereby covenants that it shall notify the Trustee at least 30 days in advance of any change in its
fiscal year. 
  
 (b) So long as not contrary to the then current
recommendations of the American Institute of Certified Public Accountants, the year-end financial statements delivered pursuant to Section 4.02 shall be accompanied by a written statement of the Company’s independent public accountants (which
shall be a firm of established national reputation) that in making the examination necessary for certification of such financial statements nothing has come to their attention that would lead them to believe that the Company has violated any
provisions of Sections 4.07, 4.09, 4.10, 4.11 or 4.15 of this Indenture (to the extent such provisions relate to accounting matters) or, if any such violation has occurred, specifying the nature and period of existence thereof. Where such financial
statements are not accompanied by such a written statement, the Company shall furnish the Trustee with an Officers’ Certificate stating that any such written statement would be contrary to the then current recommendations of the American
Institute of Certified Public Accountants. 
  
 (c) The Company and
the Subsidiary Guarantors will, so long as any of the Securities are outstanding, deliver to the Trustee forthwith upon any Officer becoming aware of any Default or Event of Default or default in the performance of any covenant, agreement or
condition contained in this Indenture, an Officers’ Certificate specifying such Default or Event of Default and what action the Company or any Subsidiary Guarantor proposes to take with respect thereto. 
  
 SECTION 4.04. Maintenance of Office or Agency. The Company will
maintain in the Borough of Manhattan, The City of New York, an office or agency where Securities may be surrendered for registration of transfer or exchange or for presentation for payment and where notices and demands to or upon the Company in
respect of the Securities and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any 

  

 29 

 
time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 11.02. If at any time the Company shall fail to maintain any required office or agency or shall fail to furnish the Trustee with the address
thereof, such surrenders, presentations, notices and demands may be made or served at the corporate trust office of the Trustee. 
  
 Subject to Section 2.03, the Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or
surrendered for any or all such purposes and may from time to time rescind such designations; provided, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the
Borough of Manhattan, The City of New York, for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 
  
 SECTION 4.05. Corporate Existence. The Company will do or cause to be
done all things necessary to preserve and keep in full force and effect its corporate existence and the corporate, partnership or other existence of each Subsidiary and all rights (charter and statutory) and franchises of the Company and the
Subsidiaries; provided, that the Company shall not be required to preserve the corporate existence of any Subsidiary, or any such right or franchise, if the Company shall determine that the preservation thereof is no longer desirable in the
conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders. 
  
 SECTION 4.06. Waiver of Stay, Extension or Usury Laws. The Company and each Subsidiary Guarantor covenants (to the extent that each may lawfully do
so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension, or usury law or other law, which would prohibit or forgive the Company or any Subsidiary Guarantor from
paying all or any portion of the principal of, premium, if any, or interest on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture;
and (to the extent that it may lawfully do so) each of the Company and the Subsidiary Guarantors hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power
herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 
  
 SECTION 4.07. Payment of Taxes and Other Claims. The Company shall pay or discharge or cause to be paid or discharged, before the same shall become
delinquent, (a) all taxes, assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary and (b) all lawful claims for labor, materials and supplies
which, if unpaid, might by law become a Lien upon the property of the Company or any Subsidiary; provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings. 
  

 30 

 SECTION 4.08. Maintenance of Properties and Insurance. (a) The Company shall cause all properties
used or held for use in the conduct of its business or the business of any Subsidiary to be maintained and kept in good condition, repair and working order (ordinary wear and tear excepted) and supplied with all necessary equipment and shall cause
to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously
conducted at all times; provided, however, that nothing in this Section shall prevent the Company from discontinuing the operation or maintenance of any such property, or disposing of it, if such discontinuance or disposal is, in the
judgment of the Company, desirable in the conduct of its business and not disadvantageous in any material respect to the Holders. 
  
 (b) The Company shall provide or cause to be provided, for itself and each of its Subsidiaries, insurance (including appropriate self-insurance) against
loss or damage of the kinds that, in the reasonable, good faith opinion of the Company, are adequate and appropriate for the conduct of the business of the Company and such Subsidiaries in a prudent manner, with reputable insurers or with the
government of the United States or an agency or instrumentality thereof, in such amounts, with such deductibles, and by such methods as shall be customary, in the reasonable, good faith opinion of the Company, for corporations similarly situated in
the industry. 
  
 SECTION 4.09. Limitation on Incurrence of
Additional Indebtedness. 
  
 (a) The Company will not, and
will not permit any of its Restricted Subsidiaries to, directly or indirectly, issue, incur, assume, guarantee, become liable, contingently or otherwise, with respect to or otherwise become responsible for the payment of (collectively,
“incur”) any Indebtedness; provided, however, that if no Default or Event of Default shall have occurred and be continuing at the time or as a consequence of the incurrence of such Indebtedness, the Company or its Restricted
Subsidiaries may incur Indebtedness if, on a pro forma basis, after giving effect to such incurrence and the application of the proceeds therefrom, either of the following tests shall have been satisfied: (i) the Adjusted Consolidated EBITDA
Coverage Ratio would have been at least 2.0 to 1.0; or (ii) Adjusted Consolidated Net Tangible Assets would have been greater than 200% of Indebtedness of the Company and its Restricted Subsidiaries. 
  
 (b) Notwithstanding the foregoing, if no Default or Event of Default shall
have occurred and be continuing at the time or as a consequence of the incurrence of such Indebtedness, the Company and its Restricted Subsidiaries may incur Permitted Indebtedness. For purposes of determining compliance with this Section 4.09:

  
 (i) in the event that an item of proposed
Indebtedness meets the criteria of more than one of the categories of Permitted Indebtedness as of the date of incurrence thereof or is entitled to be incurred pursuant to Section 4.09(a) as of the date of incurrence thereof, the Company shall, in
its sole discretion, classify (or later classify in whole or in part, in its sole discretion) such item of Indebtedness in any manner that complies with this Section 4.09, and 
  
 (ii) for purposes of determining compliance with any dollar-denominated restriction on the incurrence of
Indebtedness denominated in a foreign currency, the dollar-equivalent principal amount of such Indebtedness incurred pursuant thereto shall be calculated based on the relevant currency. 
  

 31 

 Accrual of interest or dividends, the accretion of accreted value or liquidation preference and the payment of interest
or dividends in the form of additional Indebtedness will not be deemed to be an incurrence of Indebtedness for purposes of this Section 4.09. 
  
 (c) Any Indebtedness of a Person existing at the time such Person becomes a Restricted Subsidiary (whether by merger, consolidation, acquisition or
otherwise) shall be deemed to be incurred by such Restricted Subsidiary at the time it becomes a Restricted Subsidiary. 
  
 SECTION 4.10. Limitation on Restricted Payments. (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, make any Restricted Payment, unless: 
  
 (i) no Default or Event of Default shall have occurred and be continuing at the time of or immediately after giving effect to such Restricted Payment; 
  

(ii) at the time of and immediately after giving effect to such Restricted Payment, the Company would be able to incur at least $1.00
of additional Indebtedness (other than Permitted Indebtedness) pursuant to Section 4.09(a); and 
  
 (iii) immediately after giving effect to such Restricted Payment, the aggregate of all Restricted Payments declared or made after the
Reference Date does not exceed the sum of (A) 50% of the Consolidated Net Income of the Company and its Restricted Subsidiaries (or in the event such Consolidated Net Income shall be a deficit, minus 100% of such deficit) during the period (treated
as one accounting period) subsequent to the Reference Date and ending on the last day of the fiscal quarter immediately preceding the date of such Restricted Payment; (B) the aggregate Net Cash Proceeds, and the fair market value of property other
than cash (as determined in good faith by the Company’s Board of Directors and evidenced by a resolution of such Board), received by the Company during such period from any Person other than a Subsidiary of the Company as a result of the
issuance or sale of Capital Stock of the Company (other than any Disqualified Stock and other than Preferred Shares issued in the Preferred Stock Offering), other than in connection with the conversion of Indebtedness or Disqualified Stock; (C) the
aggregate Net Cash Proceeds, and the fair market value of property other than cash (as determined in good faith by the Company’s Board of Directors and evidenced by a resolution of such Board), received by the Company during such period from
any Person other than a Subsidiary of the Company as a result of the issuance or sale of any Indebtedness or Disqualified Stock to the extent that at the time the determination is made such Indebtedness or Disqualified Stock, as the case may be, has
been converted into or exchanged for Capital Stock of the Company (other than Disqualified Stock); and (D)(i) in case any Unrestricted Subsidiary has been redesignated a Restricted Subsidiary, an amount equal to the lesser of (x) the book value
(determined in accordance with GAAP) at the date of such redesignation of the aggregate Investments made by the Company and its Restricted Subsidiaries in such Unrestricted Subsidiary and (y) the fair market value of such Investments in such
Unrestricted Subsidiary 

  

 32 

 
at the time of such redesignation, as determined in good faith by the Company’s Board of Directors, including a majority of the Company’s
Disinterested Directors, whose determination shall be conclusive and evidenced by a resolution of such Board; or (ii) in case any Restricted Subsidiary has been redesignated an Unrestricted Subsidiary, minus the greater of (x) the book value
(determined in accordance with GAAP) at the date of redesignation of the aggregate Investments made by the Company and its Restricted Subsidiaries in such Restricted Subsidiary and (y) the fair market value of such Investments in such Restricted
Subsidiary at the time of such redesignation, as determined in good faith by the Company’s Board of Directors, including a majority of the Company’s Disinterested Directors, whose determination shall be conclusive and evidenced by a
resolution of such Board. 
  
 (b) Notwithstanding the foregoing,
the above limitations will not prevent (i) the payment of any dividend within 60 days after the date of declaration thereof, if at such date of declaration such payment complied with the provisions hereof; (ii) the making of any Restricted Payment
in exchange for, or out of the net proceeds of the substantially concurrent sale (other than to a Restricted Subsidiary of the Company) of, Capital Stock (other than Disqualified Stock) of the Company; (iii) any dividend or other distribution
payable from a Restricted Subsidiary to the Company or any other Restricted Subsidiary; (iv) regularly quarterly dividends on the 6.00% Cumulative Convertible Preferred Stock, the 5.00% Cumulative Convertible Preferred Stock or the 4.125% Cumulative
Convertible Preferred Stock of the Company outstanding on the Issue Date, provided that no Default or Event of Default shall have occurred and be continuing at the time of or immediately after giving effect to any such Restricted Payment; (v)
repurchases, redemptions or other acquisitions or retirements for value of any Capital Stock from employees or directors of the Company or any Restricted Subsidiary in an aggregate amount not to exceed $3,000,000 in any calendar year; and (vi) other
Restricted Payments not in excess of $35,000,000 in the aggregate since the Issue Date, provided that no Default or Event of Default shall have occurred and be continuing at the time of or immediately after giving effect to any such
Restricted Payment. Any Restricted Payment described in the preceding clause (iii) shall be excludable in the calculation of the amount of Restricted Payments, and any Restricted payment described in any other clause shall be included in the
calculation. 
  
 SECTION 4.11. Limitation on Sale of Assets.
(a) The Company will not, and will not permit any Restricted Subsidiary to, make any Asset Sale unless: 
  
 (i) the Company (or its Restricted Subsidiaries, as the case may be) receives consideration at the time of such sale or other disposition
at least equal to the fair market value thereof (as determined in good faith by the Company’s Board of Directors and evidenced by a resolution of such Board, including a majority of the Company’s Disinterested Directors, in the case of any
Asset Sales or series of related Asset Sales having a fair market value of $50,000,000 or greater); 
  
 (ii) (A) the consideration consists of cash, cash equivalents, Permitted Financial Investments or property, equipment, leasehold interests
or other assets used in the Oil and Gas Business (“Permitted Consideration”) or (B) the portion of the consideration that does not constitute Permitted Consideration, together with all other consideration received for Asset Sales since the
Issue Date that does not constitute Permitted Consideration, has a fair market value of no more than 10% of ACNTA; and 
  

 33 

 (iii) the Net Available Proceeds received by the Company (or its Restricted Subsidiaries,
as the case may be) from such Asset Sale are applied in accordance with paragraphs (b) or (c) hereof. 
  
 (b) The Company may apply such Net Available Proceeds within 365 days after receipt of Net Available Proceeds from any Asset Sale, to: (i) the repayment
of Indebtedness of the Company or a Restricted Subsidiary under Credit Facilities or other Senior Indebtedness, including any mandatory redemption or repurchase or optional redemption of the Existing Notes or the Securities; (ii) make an Investment
in assets used in the Oil and Gas Business; or (iii) develop by drilling the Company’s oil and gas reserves. 
  
 (c) If, upon completion of the 365-day period referred to above, any portion of the Net Available Proceeds of any Asset Sale shall not have been applied
by the Company as described in clauses (i), (ii) or (iii) of the immediately preceding paragraph and such remaining Net Available Proceeds, together with any remaining net cash proceeds from any prior Asset Sale (such aggregate constituting
“Excess Proceeds”), exceed $40,000,000, then the Company will be obligated to make an offer (the “Net Proceeds Offer”) to purchase the Securities and any other Senior Indebtedness in respect of which such an offer to purchase is
required to be made concurrently with the Net Proceeds Offer having an aggregate principal amount equal to the Excess Proceeds (such purchase to be made on a pro rata basis if the amount available for such repurchase is less than the principal
amount of the Securities and other Senior Indebtedness tendered in such Net Proceeds Offer) at a purchase price of 100% of the principal amount thereof plus accrued and unpaid interest on the Securities and other Senior Indebtedness so repurchased
to the date of repurchase. Upon the completion of the Net Proceeds Offer, the amount of Excess Proceeds will be reset to zero. 
  
 (d) The Company shall commence a Net Proceeds Offer by preparing and mailing a notice to the Trustee, the Paying Agent and each Holder as of such record
date as the Company shall establish (upon written notice to the Trustee). Notice of a Net Proceeds Offer to purchase the Securities will be made on behalf of the Company not less than 25 Business Days nor more than 60 Business Days before the
payment date of the Net Proceeds Offer (the “Net Proceeds Payment Date”), and shall set forth the Net Proceeds Offer Amount and the Net Proceeds Payment Date and refer to and summarize the material points contained in Sections 4.11(d) and
(e) hereof. Securities tendered to the Company pursuant to a Net Proceeds Offer will cease to accrue interest after the Net Proceeds Payment Date. For purposes of this covenant, the term “Net Proceeds Offer Amount” means the principal of
outstanding Securities in an aggregate principal amount equal to any remaining Net Available Proceeds (rounded to the next lowest $1,000). If the Net Proceeds Payment Date is on or after an interest payment record date and on or before the related
interest payment date, any accrued interest payable on such interest payment date will be paid to the Person in whose name a Security is registered at the close of business on such record date, and no additional interest will be payable to Holders
who tender Securities pursuant to the Net Proceeds Offer. 
  
 (e)
On the Net Proceeds Payment Date, the Company will (i) accept for payment Securities and any other Senior Indebtedness in respect of which such an offer to purchase is required to be made concurrently with the Net Proceeds Offer or portions thereof
pursuant to the 

  

 34 

 
Net Proceeds Offer in an aggregate principal amount equal to the Net Proceeds Offer Amount or such lesser amount as has been tendered, (ii) deposit with the
Paying Agent (or if the Company or a Subsidiary is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the purchase price of all Securities and such other Senior Indebtedness or portions thereof so tendered in an aggregate
principal amount equal to the Net Proceeds Offer Amount or such lesser amount, including any accrued and unpaid interest thereon, and (iii) deliver or cause to be delivered to the Trustee, Securities so accepted together with an Officers’
Certificate stating the Securities or portions thereof tendered to the Company. If the aggregate principal amount of Securities and such other Senior Indebtedness tendered exceeds the Net Proceeds Offer Amount, the Trustee will select the Securities
and other Senior Indebtedness to be purchased (in integral multiples of $1,000) on a pro rata basis based on the principal amount of Securities and other Senior Indebtedness so tendered and notify the Company, the Registrar and the Paying Agent. The
Paying Agent, upon instruction of the Company, will promptly mail or deliver to Holders of Securities so accepted payment in an amount equal to the purchase price (representing those funds received pursuant to clause (ii) of this Section 4.11(e)),
and the Company will execute and the Trustee will promptly authenticate and mail or make available for delivery to Holders a new Security equal in principal amount to any unpurchased portion of the Security surrendered. Any Securities not so
accepted will be promptly mailed or delivered to the Holder thereof by the Company, or, if the Company so directs the Trustee, by the Trustee on behalf of the Company at the Company’s expense. The Company will publicly announce the results of
the Net Proceeds Offer on or as soon as practicable after the Net Proceeds Payment Date. For purposes of this Section 4.11, the Trustee will act as the Paying Agent. 
  
 (f) The Company will comply with Section 14 of the Exchange Act and the provisions of Regulation 14E and any other tender
offer rules under the Exchange Act and any other federal and state securities laws, rules and regulations which may then be applicable to any Net Proceeds Offer. 
  
 (g) During the period between any Asset Sale and the application of the Net Available Proceeds therefrom in accordance with
this covenant, all Net Available Proceeds shall be maintained in a segregated account and shall be invested in Permitted Financial Investments. 
  
 SECTION 4.12. Limitation on Liens Securing Indebtedness. The Company will not, and will not permit any Restricted Subsidiary to, create, incur,
assume or suffer to exist any Liens (other than Permitted Liens) upon any of their respective properties securing any Indebtedness of the Company or any Restricted Subsidiary, unless the Securities or a Guarantee are equally and ratably secured;
provided, that if such Indebtedness is expressly subordinated to the Securities or a Guarantee, the Lien securing such Indebtedness will be subordinated and junior to the Lien securing the Securities or such Guarantee. 
  
 SECTION 4.13. Limitation on Sale/Leaseback Transactions. The Company
will not, and will not permit any of its Restricted Subsidiaries to, enter into any Sale/Leaseback Transaction with any Person (other than the Company or any other Restricted Subsidiary) unless (i) the Company or such Restricted Subsidiary, as the
case may be, would be able to incur Indebtedness in a principal amount equal to the Attributable Indebtedness with respect to such Sale/Leaseback Transaction in accordance with Section 4.09 or (ii) the Company or such Restricted Subsidiary receives
proceeds from such 

  

 35 

 
Sale/Leaseback Transaction at least equal to the fair market value thereof (as determined in good faith by the Company’s Board of Directors, whose
determination in good faith, evidenced by a resolution of such Board shall be conclusive) and such proceeds are applied in the same manner and to the same extent as Net Available Proceeds and Excess Proceeds from an Asset Sale. 
  
 SECTION 4.14. Limitation on Payment Restrictions Affecting Subsidiaries.
The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any consensual encumbrance or consensual restriction on the ability of any
Restricted Subsidiary of the Company to (i) pay dividends or make any other distributions on its Capital Stock to the Company or a Restricted Subsidiary, (ii) pay any Indebtedness owed to the Company or a Restricted Subsidiary of the Company; (iii)
make loans or advances to the Company or a Restricted Subsidiary of the Company; or (iv) transfer any of its properties or assets to the Company or a Restricted Subsidiary of the Company (each, a “Payment Restriction”), except for (a)
encumbrances or restrictions under Credit Facilities; provided, that any Payment Restrictions thereunder (other than, with respect to (iv) above, customary restrictions in security agreements or other loan documents thereunder securing or
governing Indebtedness of a Restricted Subsidiary) may be imposed only upon the acceleration of the maturity of the Indebtedness thereunder; (b) consensual encumbrances or consensual restrictions binding upon any Person at the time such Person
becomes a Restricted Subsidiary of the Company (unless the agreement creating such consensual encumbrances or consensual restrictions was entered into in connection with, or in contemplation of, such entity becoming a Restricted Subsidiary); (c)
consensual encumbrances or consensual restrictions under any agreement that refinances or replaces any agreement described in clauses (a) and (b) above, provided that the terms and conditions of any such restrictions are in the aggregate no
less favorable to the holders of the Securities than those under the agreement so refinanced or replaced; and (d) customary non-assignment provisions in leases, purchase money financings and any encumbrance or restriction due to applicable law.

  
 SECTION 4.15. Limitation on Transactions with Affiliates.
The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into any transaction or series of transactions (including, without limitation, the sale, purchase or lease of any assets or properties
or the rendering of any services) with any Affiliate or beneficial owner (as defined in Rules 13d-3 and 13d-5 under the Exchange Act) of 10% or more of the Company’s common stock (other than with a Restricted Subsidiary of the Company) (an
“Affiliate Transaction”), on terms that are less favorable to the Company or such Restricted Subsidiary, as the case may be, than would be available in a comparable transaction with an unrelated Person. In addition, the Company will not,
and will not permit any Restricted Subsidiary of the Company to, enter into an Affiliate Transaction, or any series of related Affiliate Transactions having a value of (a) more than $15,000,000 unless a majority of the Board of Directors of the
Company (including a majority of the Company’s Disinterested Directors) determines in good faith, as evidenced by a resolution of such Board, that such Affiliate Transaction or series of related Affiliate Transactions is fair to the Company; or
(b) more than $35,000,000, unless the Company receives a written opinion from a nationally recognized investment banking firm with total assets in excess of $1,000,000,000 that such transaction or series of transactions is fair to the Company from a
financial point of view.

 SECTION 4.16. Change of Control. (a) Following the occurrence of any Change of Control Triggering
Event, the Company shall offer (a “Change of Control Offer”) to purchase all outstanding Securities at a purchase price equal to 101% of the aggregate outstanding principal amount of the Securities, plus accrued and unpaid interest on the
Securities so purchased to the date of purchase. The Change of Control Offer shall be deemed to have commenced upon mailing of the notice described in the next succeeding paragraph and shall terminate 20 Business Days after its commencement, unless
a longer offering period is required by law. Promptly after the termination of the Change of Control Offer (the “Change of Control Payment Date”), the Company shall purchase and mail or deliver payment for all Securities tendered in
response to the Change of Control Offer. If the Change of Control Payment Date is on or after an interest payment record date and on or before the related interest payment date, any accrued interest payable on such interest payment date will be paid
to the Person in whose name a Security is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Securities pursuant to the Change of Control Offer. 
  
 (b) Within 15 days after any Change of Control Triggering Event, the Company
(with notice to the Trustee and the Paying Agent), or the Trustee at the Company’s request and expense, will mail or cause to be mailed to all Holders on the date of the Change of Control Triggering Event a notice prepared by the Company (the
“Change of Control Notice”) of the occurrence of such Change of Control Triggering Event and of the Holders’ rights arising as a result thereof. The Change of Control Notice will contain all instructions and materials necessary to
enable Holders to tender their Securities to the Company. The Change of Control Notice, which shall govern the terms of the Change of Control Offer, shall state: (1) that the Change of Control Offer is being made pursuant to this Section 4.16; (2)
the purchase price and the Change of Control Payment Date; (3) that any Security not tendered will continue to accrue interest at the stated rate; (4) that any Security accepted for payment pursuant to the Change of Control Offer shall cease to
accrue interest on the Change of Control Payment Date; (5) that Holders electing to have a Security purchased pursuant to any Change of Control Offer will be required to surrender the Security, with the form entitled “Option of Holder to Elect
Purchase” on the reverse of the Security completed, to the Company, a depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice prior to termination of the Change of Control Offer; (6) that Holders will
be entitled to withdraw their election if the Company, depositary or Paying Agent, as the case may be, receives, not later than the expiration of the Change of Control Offer, or such longer period as may be required by law, a telegram, telex,
facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security the Holder delivered for purchase and a statement that such Holder is withdrawing its election to have the Security purchased; and (7) that
Holders whose Securities are purchased only in part will be issued Securities equal in principal amount to the unpurchased portion of the Securities surrendered. 
  
 (c) On the Change of Control Payment Date, the Company shall, to the extent permitted by applicable law, (i) accept for
payment Securities or portions thereof tendered pursuant to the Change of Control Notice, (ii) if the Company appoints a depositary or Paying Agent, deposit with such depositary or Paying Agent money sufficient to pay the purchase price of all
Securities or portions thereof so tendered and (iii) deliver to the Trustee Securities so accepted together with an Officers’ Certificate stating the Securities or portions thereof tendered to the Company. The depositary, the 

  

 37 

 
Company or the Paying Agent, as the case may be, shall promptly mail to the Holders of Securities so accepted payment in an amount equal to the purchase
price (representing those funds received pursuant to clause (ii) of this Section 4.16(c)), and the Trustee shall promptly authenticate and mail to each such Holder a new Security equal in principal amount to any unpurchased portion of the Security
surrendered; provided that each such new Security will be in a principal amount of $1,000 or an integral multiple thereof. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the
Change of Control Payment Date. For purposes of this Section 4.16, the Trustee shall act as the Paying Agent. 
  
 (d) The Company will comply with Section 14 of the Exchange Act and the provisions of Regulation 14E and any other tender offer rules under the Exchange
Act and any other federal and state securities laws, rules and regulations which may then be applicable to any offer by the Company to purchase the Securities at the option of the Holders upon a Change of Control. 
  
 SECTION 4.17. Covenant Termination. (a) If at any time (i) the rating
assigned to the Securities by either S&P or Moody’s is an Investment Grade Rating and (ii) no Event of Default has occurred and is continuing under the Indenture, then upon notice thereof from the Company to the Trustee, the Company and its
Restricted Subsidiaries will no longer be subject Sections 4.09, 4.10, 4.11, 4.14, 4.15 and 4.16 and, without limiting the remainder of Article Five, the financial test set out in clause (3) of Section 5.01 shall not apply. 
  
 (b) Following any termination of the covenants under this Section 4.17, the
Company may not designate any Subsidiary to be an Unrestricted Subsidiary.

the principal of, premium, if any, and interest on, all the Securities and the performance of every other covenant and obligation of the Company under this Indenture provided, that unless the successor Person is a corporation, a corporate
co-issuer of the Securities shall be added hereto by the execution and delivery of a supplemental indenture by such co-issuer;

 (2) immediately before and after giving effect to such transaction no Default or Event of
Default exists; and 
  
 (3) either:

In connection with any consolidation, merger, sale, conveyance, lease, transfer or other disposition contemplated by this Section 5.01, the Company
shall deliver to the Trustee prior to the consummation of the proposed transaction an Officers’ Certificate to the foregoing effect and an Opinion of Counsel stating that the proposed transaction and such supplemental indenture comply with this
Indenture. 
  
 SECTION 5.02. Successor Corporation Substituted.
Upon any consolidation, merger, lease, conveyance or transfer in accordance with Section 5.01, the Trustee shall be notified by the Company and the successor Person, and the successor Person formed by such consolidation or into which the Company
is merged or to which such lease, conveyance or transfer is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor had been named as the
Company herein and thereafter (except in the case of a lease) the predecessor corporation will be relieved of all further obligations and covenants under this Indenture and the Securities. 
  
 ARTICLE SIX 
  
 DEFAULTS AND REMEDIES 
  
 SECTION 6.01. Events of Default. An “Event of Default” occurs upon: 
  
 (1) default by the Company or any Subsidiary Guarantor in the payment of principal of, or premium, if any,
on the Securities when due and payable at maturity, upon repurchase pursuant to Section 4.11 or 4.16, upon acceleration or otherwise; 
  
 (2) default by the Company or any Subsidiary Guarantor in the payment of any installment of interest on the Securities when due and

Indebtedness) of the Company, any Subsidiary Guarantor or any other Subsidiary 

  

 39 

 
(other than a Non-Recourse Subsidiary or an Unrestricted Subsidiary) if either (A) such default results in the acceleration of the maturity of any such
Indebtedness having a principal amount of $50,000,000 or more individually or, taken together with the principal amount of any other such Indebtedness the maturity of which has been so accelerated, in the aggregate, or (B) such default results from
the failure to pay when due principal of, premium, if any, or interest on, any such Indebtedness, after giving effect to any applicable grace period (a “Payment Default”), having a principal amount of $50,000,000 or more individually or,
taken together with the principal amount of any other Indebtedness under which there has been a Payment Default, in the aggregate; provided that if any such default is cured or waived or any such acceleration is rescinded, or such
Indebtedness is repaid, within a period of 30 days from the continuation of such default beyond any applicable grace period or the occurrence of such acceleration, as the case may be, such Event of Default and any consequent acceleration of the
Securities shall be rescinded, so long as any such rescission does not conflict with any judgment or decree or applicable provision of law; 
  
 (5) default in the performance, or breach of, the covenants set forth in Section 4.10 and Article Five, or in the performance, or breach
of, any other covenant or agreement of the Company or any Subsidiary Guarantor in this Indenture and failure to remedy such default within a period of 45 days after written notice thereof from the Trustee or Holders of 25% of the principal amount of
the outstanding Securities; 
  
 (6) the entry by
a court of one or more judgments or orders for the payment of money against the Company, any Subsidiary Guarantor or any other Subsidiary (other than a Non-Recourse Subsidiary or an Unrestricted Subsidiary, provided that neither the Company
nor any Restricted Subsidiary is liable, directly or indirectly, for such judgment or order) in an aggregate amount in excess of $50,000,000 (net of applicable insurance coverage by a third party insurer which is acknowledged in writing by such
insurer) that has not been vacated, discharged, satisfied or stayed pending appeal within 60 days from the entry thereof; 
  
 (7) a Guarantee by a Subsidiary Guarantor shall cease to be in full force and effect (other than a release of a Guarantee in accordance
with Section 10.04) or any Subsidiary Guarantor shall deny or disaffirm its obligations with respect thereto; 
  
 (8) the Company or any Subsidiary (other than a Non-Recourse Subsidiary or an Unrestricted Subsidiary) pursuant to or within the meaning
of any Bankruptcy Law: 
  
 (A) commences a
voluntary case or proceeding, 
  
 (B) consents
to the entry of an order for relief against it in an involuntary case or proceeding, 
  

 40 

 (C) consents to the appointment of a Custodian of it or for all or substantially all of
its property, 
  
 (D) makes a general assignment
for the benefit of its creditors, or 
  
 (E)
admits in writing that it generally is unable to pay its debts as the same become due; or 
  
 (9) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

such case) against the Company or any Subsidiary (other than a Non-Recourse Subsidiary or an Unrestricted Subsidiary) in an involuntary case or proceeding, 
  
 (B) appoints a Custodian of the Company or any Subsidiary (other than a Non-Recourse Subsidiary or an Unrestricted Subsidiary) or for all
or substantially all of its property, or 
  
 (C)
orders the liquidation of the Company or any Subsidiary (other than a Non- Recourse Subsidiary or an Unrestricted Subsidiary), and the order or decree remains unstayed and in effect for 60 days. 
  
 The term “Bankruptcy Law” means Title 11, U.S. Code or any similar
federal or state law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law. 
  
 SECTION 6.02. Acceleration. If an Event of Default (other than an Event of Default specified in clauses (8) or (9))
under Section 6.01 occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% of the principal amount of the outstanding Securities may declare the unpaid principal of and premium, if any, or the Change of
Control purchase price if the Event of Default includes failure to pay the Change of Control purchase price, and accrued and unpaid interest on, all the Securities then outstanding to be due and payable, by a notice in writing to the Company (and to
the Trustee, if given by Holders), and upon any such declaration such principal, premium, if any, and accrued and unpaid interest shall become immediately due and payable, notwithstanding anything contained in this Indenture or the Securities to the
contrary. If an Event of Default specified in clauses 8 or 9 above occurs, all unpaid principal of, and premium, if any, and accrued and unpaid interest on, the Securities then outstanding will become due and payable, without any declaration or
other act on the part of the Trustee or any Holder. 
  
 The
Holders of a majority of the principal amount of the outstanding Securities, by written notice to the Company, the Subsidiary Guarantors and the Trustee, may rescind and annul a declaration of acceleration and its consequences if (1) the Company or
any Subsidiary Guarantor has paid or deposited with such Trustee a sum sufficient to pay (A) all overdue installments of interest on all the Securities, (B) the principal of, and premium, if any, on any Securities that have become due otherwise than
by such declaration of acceleration and interest thereon at 

  

 41 

 
the rate or rates prescribed therefor in the Securities, (C) to the extent that payment of such interest is lawful, interest on the defaulted interest at the
rate or rates prescribed therefor in the Securities, and (D) all money paid or advanced by the Trustee thereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; (2) all Events of
Default, other than the non-payment of the principal of any Securities that have become due solely by such declaration of acceleration, have been cured or waived as provided in this Indenture; and (3) the rescission would not conflict with any
judgment or decree of a court of competent jurisdiction. No such rescission will affect any subsequent Event of Default or impair any right consequent thereon. 
  

SECTION 6.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may, but is not obligated to, pursue, in its own name
and as trustee of an express trust, any available remedy by proceeding at law or in equity to collect the payment of principal or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture. If an
Event of Default specified under clauses (8) or (9) of Section 6.01 occurs with respect to the Company at a time when the Company is the Paying Agent, the Trustee shall automatically assume the duties of Paying Agent. 
  
 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 Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or
acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative. 
  
 SECTION 6.04. Waiver of Past Defaults. Subject to Sections 6.07 and 9.02, the Holders of at least a majority of the principal amount of the
outstanding Securities by notice to the Trustee may waive an existing Default or Event of Default and its consequences, except a Default or Event of Default in payment of principal or interest on the Securities, including any optional redemption
payments or Change of Control or Net Proceeds Offer payments. 
  
 SECTION 6.05. Control by Majority. The Holders of a majority in principal amount of the Securities will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on such Trustee, provided that (1) such direction is not in conflict with any rule of law or with this Indenture and (2) the Trustee may take any other action deemed proper by such Trustee that is not
inconsistent with such direction. 
  
 SECTION 6.06. Limitation
on Remedies. No Holder of any of the Securities will have any right to institute any proceeding, judicial or otherwise, or for the appointment of a receiver or trustee or pursue any remedy under this Indenture, unless: 
  
 (1) such Holder has previously given notice to the Trustee
of a continuing Event of Default, 
  
 (2) the
Holders of not less than 25% of the principal amount of the outstanding Securities have made written request to such Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee under this Indenture, 
  

 42 

 (3) such Holder or Holders have offered to such Trustee indemnity reasonably satisfactory
to it against the costs, expenses and liabilities to be incurred in compliance with such request, 
  
 (4) such Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any proceeding, and

  
 (5) no direction inconsistent with such
written request has been given to such Trustee during such 60-day period by the Holders of a majority of the principal amount of the outstanding Securities. 
  
 A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over other Holders. 
  
 SECTION 6.07. Rights of Holders to Receive Payment. Notwithstanding
any other provision of this Indenture, the Holder of any Securities will have the right, which is absolute and unconditional, to receive payment of the principal of and interest on such Securities on the stated maturity therefor and to institute
suit for the enforcement of any such payment, and such right may not be impaired without the consent of such Holder. 
  
 SECTION 6.08. Collection Suit by Trustee. If an Event of Default in payment of principal, premium, if any, or interest specified in Section
6.01(1), (2) or (3) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or any Subsidiary Guarantor for the whole amount of principal, premium, if any, and interest
remaining unpaid with respect to the Securities, and interest on overdue principal and premium, if any, and, to the extent lawful, interest on overdue interest, and such further amounts as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation and expenses of the Trustee, its agents and counsel. 
  
 SECTION 6.09. Trustee May File Proofs of Claim. (a) 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 Holders allowed in any judicial proceedings relative to the Company, the Subsidiary Guarantors, their creditors or their property and may collect and receive any money or securities or
other property payable or deliverable on any such claims and to distribute the same. 
  
 (b) Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting
the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
  
 SECTION 6.10. Priorities. If the Trustee collects any money pursuant to this Article Six, it shall pay out the money in the following order:

  
 First: to the Trustee for amounts due under
Section 7.07; 
  
 Second: to Holders for amounts
due and unpaid on the Securities for principal and interest, ratably, without 

  

 43 

 
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 Holders
pursuant to this Section 6.10. 
  
 SECTION 6.11. Undertaking
for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as 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 and expenses, against any party litigant in the suit, having due regard to the merits and
good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07, or a suit by Holders of more than 10% in principal amount of the then
outstanding Securities. 
  
 ARTICLE SEVEN 
  
 TRUSTEE 
  
 SECTION 7.01. Duties of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall
exercise such rights and powers vested in it by this Indenture and use the same degree of care and skill in such exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 

 
 (b) Except during the continuance of an Event of Default: 
  
 (1) The Trustee need perform only those duties that are
specifically set forth (or incorporated by reference) in this Indenture and no others. 
  
 (2) In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of
the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of certificates or opinions specifically required by any provision hereof to be
furnished to it, the Trustee shall examine such certificates and opinions to determine whether or not they conform to the requirements of this Indenture. 
  
 (c) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except
that: 
  
 (1) This paragraph (c) does not limit
the effect of paragraph (b) of this Section. 
  
 (2) The Trustee shall not be liable for any error of judgment made in good faith by an officer of the Trustee, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts. 
  

 44 

 (3) The Trustee shall not be liable with respect to action it takes or omits to take in
good faith in accordance with a direction received by it pursuant to Section 6.05, and the Trustee shall be entitled from time to time to request such a direction. 
  
 (d) Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of
this Section. 
  
 (e) The Trustee shall be under no obligation and
may refuse to perform any duty or exercise any right, duty or power hereunder unless it receives indemnity reasonably satisfactory to it against any loss, liability or expense. No provision of this Indenture shall require the Trustee to expend or
risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it. 
  
 (f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds
except to the extent required by law. 
  
 SECTION 7.02. Rights
of Trustee. Subject to Section 7.01: 
  
 (a) The Trustee may
conclusively rely on and shall be fully protected in acting or refraining from acting upon any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such
further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company,
personally or by agent or attorney, to the extent reasonably required by such inquiry or investigation at the expense of the Company and shall incur no liability of any kind by reason of such inquiry or investigation. 
  
 (b) Before the Trustee acts or refrains from acting, it may require an
Officers’ Certificate or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such certificate or opinion. 
  
 (c) The Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed
with due care. 
  
 (d) The Trustee shall not be liable for any
action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers. 
  

 45 

 (e) The Trustee may consult with counsel of its selection and the advice of such counsel or any Opinion
of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and reliance thereon. 
  
 (f) In no event shall the Trustee be responsible or liable for special, indirect, or consequential loss or damage of any
kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 
  
 (g) The Trustee shall not be deemed to have notice of any Default or Event of
Default unless a Trust Officer has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities and
this Indenture. 
  
 (h) The rights, privileges, protections,
immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person
employed to act hereunder. 
  
 (i) The Trustee may request that
the Company deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture. 
  
 SECTION 7.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner
or pledgee of Securities and may otherwise deal with the Company or its Subsidiaries or Affiliates with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee must comply with Sections
7.10 and 7.11. 
  
 SECTION 7.04. Trustee’s Disclaimer.
The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities or any prospectus, offering or solicitation
documents, and it shall not be responsible for any statement in the Securities other than its certificate of authentication. 
  
 SECTION 7.05. Notice of Defaults. If a Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to each Holder
pursuant to Section 11.02 a notice of the Default within 90 days after it occurs. Except in the case of a Default in any payment on any Security, the Trustee may withhold the notice if and so long as the board of directors, executive committee or a
trust committee of officers in good faith determines that withholding the notice is in the interests of Holders. 
  
 SECTION 7.06. Reports by Trustee to Holders. Within 60 days after each April 1, beginning with the April 1 following the date of this Indenture,
the Trustee shall mail to each Holder a brief report dated as of such April 1 that complies with TIA Section 313(a), but only if such report is required in any year under TIA Section 313(a). The Trustee also shall comply with TIA Sections 313(b) and
313(c). A copy of each report at the time of its mailing to Holders shall be filed with the SEC and each stock exchange on which the Securities are listed. The Company shall notify the Trustee in writing when the Securities become listed on any
national securities exchange or of any delisting thereof. 
  

 46 

 SECTION 7.07. Compensation and Indemnity. The Company and the Subsidiary Guarantors jointly and
severally agree to pay the Trustee from time to time reasonable compensation for its services (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust). The Company and the
Subsidiary Guarantors jointly and severally agree to reimburse the Trustee upon request for all reasonable out-of-pocket expenses, disbursements and advances incurred by it. Such expenses shall include when applicable the reasonable compensation and
expenses of the Trustee’s agents and counsel. 
  
 The Trustee
shall not be under any obligation to institute any suit, or take any remedial action under this Indenture, or to enter any appearance or in any way defend any suit in which it may be a defendant, or to take any steps in the execution of the trusts
created hereby or thereby or in the enforcement of any rights and powers under this Indenture, until it shall be indemnified to its satisfaction against any and all reasonable expenses, disbursements and advances incurred or made by the Trustee in
accordance with any provisions of this Indenture, including compensation for services, costs, expenses, outlays, counsel fees and other disbursements, and against all liability (including fees and expenses incurred by the Trustee pursuant to the
penultimate paragraph of Section 7.08) not due to its negligence or willful misconduct. The Company and the Subsidiary Guarantors jointly and severally agree to indemnify the Trustee against any loss, liability, claim, damage or expenses incurred by
it arising out of or in connection with the acceptance and administration of the trust and its duties hereunder as Trustee, Registrar and/or Paying Agent, including the costs and expenses of enforcing this Indenture against the Company (including
with respect to this Section 7.07) and of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. The Trustee shall notify the Company and the Subsidiary Guarantors of
any claim of which a Trust Officer has received written notice for which it may seek indemnity; however, unless the position of the Company is prejudiced by such failure, the failure of the Trustee to promptly notify the Company shall not limit its
right to indemnification. The Company shall defend each such claim and the Trustee shall cooperate in the defense. The Trustee may retain separate counsel and the Company shall reimburse the Trustee for the reasonable fees and expenses of such
counsel. The Company need not pay for any settlement made without its consent. 
  
 Neither the Company nor the Subsidiary Guarantors shall be obligated to reimburse any expense or indemnify against any loss or liability incurred by the Trustee through the Trustee’s own negligence or willful
misconduct. To secure the payment obligations of the Company and the Subsidiary Guarantors in this Section, the Trustee shall have a claim prior to that of the Holders of the Securities on all money or property held or collected by the Trustee,
except that held in trust to pay principal of and interest on particular Securities. The Trustee’s right to receive payment of any amounts due under this Section 7.07 shall not be subordinate to any other liability or Indebtedness of the
Company. 
  
 When the Trustee incurs expenses or renders services
after the occurrence of any Event of Default specified in Sections 6.01(8) or (9), the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. 
  

 47 

 The benefits of this section shall survive termination of this Indenture and resignation or removal of
the Trustee. 
  
 SECTION 7.08. Replacement of Trustee. The
Trustee may resign by so notifying the Company and the Subsidiary Guarantors. The Holders of a majority in principal amount of the Securities may remove the Trustee by so notifying the Trustee, in writing. The Company may remove the Trustee if:

  
 (1) the Trustee fails to comply with Section
7.10; 
  
 (2) the Trustee is adjudged a bankrupt
or an insolvent; 
  
 (3) a receiver or other
public officer takes charge of the Trustee or its property; or 
  
 (4) the Trustee becomes incapable of acting as Trustee hereunder. 
  
 If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the Securities may appoint a successor Trustee to replace the successor Trustee appointed by the Company. 
  
 A successor Trustee shall deliver a written acceptance of its appointment to
the retiring Trustee and to the Company and the Subsidiary Guarantors. Immediately after that and upon payment of its charges hereunder, the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee, subject to the
lien provided for in Section 7.07, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. A successor Trustee shall mail
notice of its succession to each Holder. 
  
 If a successor
Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of a majority in principal amount of the Securities may petition, at the expense of the Company, any court
of competent jurisdiction for the appointment of a successor Trustee. 
  
 If the Trustee fails to comply with Section 7.10, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. Any successor Trustee shall comply with TIA Section
310(a)(5). 
  
 SECTION 7.09. Successor Trustee by Merger, etc.
If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust assets to, another corporation, the successor corporation without any further act shall be the successor Trustee; provided
such corporation or association shall be otherwise eligible and qualified under this Article and shall notify the Company of its successor hereunder. 
  
 SECTION 7.10. Eligibility; Disqualification. This Indenture shall always have a Trustee which satisfies the requirements of TIA Section 310(a)(1).
The Trustee shall always have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. The Trustee shall also comply with TIA Section 310(b). 
  

 48 

 SECTION 7.11. Preferential Collection of Claims Against Company. The Trustee shall comply with TIA
Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein. 
  
 ARTICLE EIGHT 
  
 DISCHARGE OF INDENTURE 
  
 SECTION 8.01. Option to Effect Legal Defeasance or Covenant Defeasance. 
  
 The Company may, at the option of its Board of Directors evidenced by a resolution set forth in an Officers’
Certificate, at any time, with respect to the Securities, elect to exercise its rights pursuant to either Section 8.02 or 8.03 with respect to all outstanding Securities upon compliance with the conditions set forth below in this Article Eight.

  
 SECTION 8.02. Legal Defeasance and Discharge. Upon the
Company’s exercise under Section 8.01 of the option applicable to this Section 8.02, the Company shall be deemed to have been discharged from its obligations with respect to all outstanding Securities on the date all conditions set forth below
are satisfied (hereinafter, “Legal Defeasance”). For this purpose, such Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Securities, which shall
thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all its other obligations under such Securities and this
Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (a) the rights of
Holders of outstanding Securities to receive solely from the trust fund described in Section 8.04, and as more fully set forth in such Section, payments in respect of the principal of, premium, if any, and interest on such Securities when such
payments are due, (b) the Company’s obligations with respect to such Securities under Sections 2.03, 2.04, 2.06, 2.07, 2.09 and 4.04, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s
obligations in connection therewith (including, but not limited to, Section 7.07) and (d) this Article Eight. Subject to compliance with this Article Eight, the Company may exercise its option under this Section 8.02 notwithstanding the prior
exercise of its option under Section 8.03 with respect to the Securities. 
  
 SECTION 8.03. Covenant Defeasance. Upon the Company’s exercise under Section 8.01 of the option applicable to this Section 8.03, the Company shall be released from its obligations under the covenants
contained in the second sentence of Section 4.02, Sections 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15 and 4.16 and Article Five with respect to the outstanding Securities on and after the date the conditions set forth below are
satisfied (hereinafter, “Covenant Defeasance”), and the Securities shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Securities shall not be deemed outstanding for accounting purposes). For this
purpose, such Covenant Defeasance means that, with respect to the outstanding 

  

 49 

 
Securities, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not
constitute a Default or an Event of Default under Section 6.01(5), but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 of
the option applicable to this Section 8.03, Sections 6.01(4) through 6.01(9) shall not constitute Events of Default. 
  
 SECTION 8.04. Conditions to Legal or Covenant Defeasance. The following shall be the conditions to application of either Section 8.02 or Section
8.03 to the outstanding Securities: 
  
 (a) The Company shall
irrevocably have deposited or cause to be deposited with the Trustee (or another trustee satisfying the requirements of Section 7.10 who shall agree to comply with the provisions of this Article Eight applicable to it) as trust funds in trust for
the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities, (a) cash in U.S. Legal Tender in an amount, or (b) U.S. Government Securities which through
the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, cash in U.S. Legal Tender in an amount, or (c) a combination thereof, in such
amounts, as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge and which shall be applied by the Trustee
(or other qualifying trustee) to pay and discharge the principal of, premium, if any, and interest on the outstanding Securities on the Maturity Date or on the applicable redemption date, as the case may be, of such principal or installment of
principal, premium, if any, or interest and in accordance with the terms of this Indenture and of such Securities; provided that the Trustee shall have been irrevocably instructed to apply such money or the proceeds of such U.S. Government
Securities to said payments with respect to the Securities. 
  
 (b) In the case of an election under Section 8.02, the Company shall have delivered to the Trustee an Opinion of Counsel confirming that (i) the Company has received from, or there has been published by, the Internal Revenue Service a
ruling or (ii) since the date hereof, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of the outstanding Securities will not
recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal
Defeasance had not occurred; 
  
 (c) In the case of an election
under Section 8.03, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of the outstanding Securities 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; 
  

 50 

 (d) No Default or Event of Default with respect to the Securities shall have occurred and be continuing
on the date of such deposit or, insofar as Subsection 6.01(8) or 6.01(9) is concerned, at any time in the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the
expiration of such period); 
  
 (e) Such Legal Defeasance or
Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, this Indenture or any other material agreement or instrument to which the Company is a party or by which the Company is bound; 
  
 (f) In the case of any election under Section 8.02 or 8.03, the Company shall
have delivered to the Trustee an Officers’ Certificate stating that the deposit made by the Company pursuant to its election under Section 8.02 or 8.03 was not made by the Company with the intent of preferring the Holders over other creditors
of the Company or with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and 
  
 (g) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent
provided for relating to either the Legal Defeasance under Section 8.02 or the Covenant Defeasance under Section 8.03 (as the case may be) have been complied with as contemplated by this Section 8.04. 
  
 SECTION 8.05. Deposited Money and U.S. Government Securities to be Held in
Trust; Other Miscellaneous Provisions. Subject to Section 8.06, all money and U.S. Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05,
the “Trustee”) pursuant to Section 8.04 in respect of the outstanding Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company or a Subsidiary Guarantor, if any, acting as Paying Agent) as the Trustee may determine, to the Holders of such Securities of all sums due and to become due thereon in respect of principal, premium, if
any, and interest, but such money need not be segregated from other funds except to the extent required by law. 
  
 The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or U.S. Government Securities
deposited pursuant to Section 8.04 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Securities. 
  
 Anything in this Article Eight to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon the Company’s request any money or U.S. Government Securities held by it as provided in Section 8.04 which, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(a)), are in excess of the amount thereof which would then be required to be deposited to effect an equivalent
Legal Defeasance or Covenant Defeasance. 
  

 51 

 SECTION 8.06. Repayment to Company. Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on any Security which is not subject to the last paragraph of Section 8.05 and has remained unclaimed for two years after such principal, and
premium, if any, or interest has become due and payable shall be paid to the Company on its request (unless an abandoned property law designates another Person) or (if then held by the Company) shall be discharged from such trust; and the Holder of
such Securities shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in the New York Times and The
Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining
will be repaid to the Company. 
  
 SECTION 8.07. Reinstatement.
If the Trustee or Paying Agent is unable to apply any U.S. Legal Tender or U.S. Government Securities in accordance with Section 8.02 or 8.03, as the case may be, by reason of any order or judgment of any court or governmental authority
enjoining, restraining, or otherwise prohibiting such application, then the Company’s obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 until
such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or
interest on any Security following 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 held by the Trustee or Paying Agent. In the event the
Company’s obligations under this Indenture and the Securities are revived and reinstated pursuant to this Section 8.07, then the obligations of each Subsidiary Guarantor under its Guarantee and this Indenture that were released pursuant to
Section 10.04 as a result of the Company’s exercise of its rights under this Article Eight shall be revived and reinstated as though such release had not occurred. 
  
 ARTICLE NINE 
  
 AMENDMENTS, SUPPLEMENTS AND WAIVERS 
  
 SECTION 9.01. Without Consent of Holders. 
  
 The Company, the Subsidiary Guarantors and the Trustee may amend or supplement this Indenture or the Securities without notice to or consent of any
Holder: 
  
 (1) to cure any ambiguity, omission,
defect or inconsistency; 
  
 (2) to comply with
Section 5.01 or 10.02; 
  
 (3) to reflect the
addition or release of any Subsidiary Guarantor, as provided for by this Indenture; 
  

 52 

 (4) to comply with any requirements of the SEC in order to effect or maintain the
qualification of this Indenture under the TIA; or 
  
 (5) to make any change that would provide any additional benefit or rights to the Holders or that does not adversely affect the rights of any Holder in any material respect. 
  
 Upon the request of the Company and the Subsidiary Guarantors, accompanied by a Board Resolution of the Company and of each
Subsidiary Guarantor authorizing the execution of any such supplemental indenture, and upon receipt by the Trustee of the documents described in Section 9.06, the Trustee shall join with the Company and the Subsidiary Guarantors in the execution of
any supplemental indenture authorized or permitted by the terms of this Indenture and make any further appropriate agreements and stipulations that may be therein contained. After an amendment or waiver under this Section becomes effective, the
Company shall mail to the Holders of each Security affected thereby a notice briefly describing the amendment or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the
validity of any such supplemental indenture. 
  
 SECTION 9.02.
With Consent of Holders. Except as provided below in this Section 9.02, the Company, the Subsidiary Guarantors and the Trustee may amend this Indenture or the Securities with the written consent (including consents obtained in connection with
a tender offer or exchange offer for Securities or a solicitation of consents in respect of Securities, provided that in each case such offer or solicitation is made to all Holders of then outstanding Securities on equal terms) of the Holders
of at least a majority of the principal amount of the outstanding Securities. 
  
 Upon the request of the Company and the Subsidiary Guarantors, accompanied by a Board Resolution of the Company and each Subsidiary Guarantor authorizing the execution of any such supplemental indenture, and upon the
filing with the Trustee of evidence of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the Opinion of Counsel described in Section 9.06, the Trustee shall join with the Company and the Subsidiary Guarantors in the
execution of such supplemental indenture. 
  
 It shall not be
necessary for the consent of the Holders under this Section to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof. 
  
 The Holders of a majority of the principal amount of the outstanding
Securities may waive compliance in a particular instance by the Company or the Subsidiary Guarantors with any provision of this Indenture or the Securities (including waivers obtained in connection with a tender offer or exchange offer for
Securities or a solicitation of consents in respect of Securities, provided that in each case such offer or solicitation is made to all Holders of the then outstanding Securities on equal terms). However, without the consent of each Holder
affected, an amendment or waiver under this Section may not: 
  
 (1) reduce the percentage of principal amount of Securities whose Holders must consent to an amendment, supplement or waiver of any provision of this Indenture or the Securities; 
  

 53 

 (2) reduce the rate or change the time for payment of interest, including default
interest, on the Securities; 
  
 (3) reduce the
principal amount of any Security or change the Maturity Date of the Securities; 
  
 (4) reduce the redemption price, including premium, if any, payable upon the redemption of any Security or change the time at which any
Security may be redeemed; 
  
 (5) reduce the
repurchase price, including premium, if any, payable upon the repurchase of any Security pursuant to Sections 4.11 or 4.16, or change the time at which any Security may or shall be repurchased thereunder; 
  
 (6) waive a Default or Event of Default in the payment of
the principal of, premium, if any, or interest on the Securities; 
  
 (7) make any Security payable in money other than that stated in the Security; 
  
 (8) impair the right to institute suit for the enforcement of principal of, premium, if any, or principal on any Security pursuant to
Sections 6.07 or 6.08, except as limited by Section 6.06; or 
  
 (9) make any change in Section 6.04 or Section 6.07 or in this sentence of this Section 9.02. 
  
 The right of any Holder to participate in any consent required or sought pursuant to any provision of this Indenture (and the obligation of the Company to
obtain any such consent otherwise required from such Holder) may be subject to the requirement that such Holder shall have been the Holder of record of any Securities with respect to which such consent is required or sought as of a date identified
by the Trustee in a notice furnished to Holders in accordance with the terms of this Indenture. 
  
 SECTION 9.03. Compliance with Trust Indenture Act. Every amendment to or supplement of this Indenture or the Securities shall comply with the TIA
as then in effect. 
  
 SECTION 9.04. Revocation and Effect of
Consents. A consent to an amendment, supplement or waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security,
even if notation of the consent is not made on any Security. However, until an amendment, supplement or waiver becomes effective, any such Holder or subsequent Holder may revoke the consent as to its Security or portion of a Security. For such
revocation to be effective, the Trustee must receive the notice of revocation before the date the amendment, supplement or waiver becomes effective. 
  
 The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment or
waiver. If the Company elects to fix a record date for such purpose, the record date shall be fixed at (i) the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of 

  

 54 

 
Holders furnished to the Trustee prior to such solicitation pursuant to Section 2.05, or (ii) such other date as the Company shall designate. If a record
date is fixed, then notwithstanding the provisions of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to consent to such amendment
or waiver or to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No consent shall be valid or effective for more than 90 days after such record date unless consent from the Holders of
the principal amount of Securities required hereunder for such amendment or waiver to be effective also shall have been given and not revoked within such 90-day period. 
  
 After an amendment, supplement or waiver becomes effective, it shall bind every Holder unless it makes a change described in
any of clauses (1) through (9) of Section 9.02. In that case the amendment, supplement or waiver shall bind each Holder of a Security who has consented to it and every subsequent Holder of a Security or portion of a Security that evidences the same
debt as the consenting Holder’s Security. 
  
 SECTION 9.05.
Notation on or Exchange of Senior Notes. If an amendment, supplement or waiver 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 about 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. 
  
 SECTION 9.06. Trustee Protected. The
Trustee shall sign any amendment or supplement or waiver authorized pursuant to this Article if the amendment or supplement or waiver does not adversely affect the rights of the Trustee. If it does adversely affect the rights of the Trustee, the
Trustee may but need not sign it. In signing such amendment or supplement or waiver the Trustee shall be provided with, and (subject to Article Seven) shall be fully protected in relying upon, an Opinion of Counsel stating that such amendment or
supplement or waiver is authorized or permitted by and complies with this Indenture. The Company may not sign an amendment or supplement until the Boards of Directors of the Company and the Subsidiary Guarantors approve it. 
  
 ARTICLE TEN 
  
 GUARANTEES 
  
 SECTION 10.01. Unconditional Guarantee. Each Subsidiary Guarantor hereby, jointly and severally, fully and unconditionally guarantees, as principal
obligor and not only as surety (such guarantee to be referred to herein as the “Guarantee”), to each Holder and to the Trustee the due and punctual payment of the principal of, premium, if any, and interest on the Securities and all other
amounts due and payable under this Indenture and the Securities by the Company whether at maturity, by acceleration, redemption, repurchase or otherwise, including, without limitation, interest on the overdue principal of, premium, if any, and
interest on the Securities, to the extent lawful, all in accordance with the terms hereof and thereof; subject, however, to the limitations set forth in Section 10.05. 
  
 Failing payment when due of any amount so guaranteed for whatever reason, the Subsidiary Guarantors will be jointly and
severally obligated to pay the same immediately. Each Subsidiary Guarantor hereby agrees that its 

  

 55 

 
obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Securities or this Indenture, the absence of
any action to enforce the same, any waiver or consent by any Holder of the Securities with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which
might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Subsidiary Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the
Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that this Guarantee will not be discharged except by complete performance of the obligations contained in the Securities,
this Indenture and in this Guarantee. If any Holder or the Trustee is required by any court or otherwise to return to the Company, any Subsidiary Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the
Company or any Subsidiary Guarantor, any amount paid by the Company or any Subsidiary Guarantor to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Subsidiary
Guarantor agrees it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Subsidiary Guarantor further agrees
that, as between each Subsidiary Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Six for the purposes of this Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article Six, such obligations
(whether or not due and payable) shall forthwith become due and payable by each Subsidiary Guarantor for the purpose of this Guarantee. 
  
 SECTION 10.02. Subsidiary Guarantors May Consolidate, etc., on Certain Terms. (a) Subject to paragraph (b) of this Section 10.02, no Subsidiary
Guarantor may consolidate or merge with or into (whether or not such Subsidiary Guarantor is the surviving Person) another Person unless (i) the Person formed by or surviving any such consolidation or merger (if other than such Subsidiary Guarantor)
assumes all the obligations of such Subsidiary Guarantor under this Indenture and the Securities pursuant to a supplemental indenture, in a form reasonably satisfactory to the Trustee and (ii) immediately after such transaction, no Default or Event
of Default exists. In connection with any consolidation or merger contemplated by this Section 10.02, the Company shall deliver to the Trustee prior to the consummation of the proposed transaction an Officers’ Certificate to the foregoing
effect and an Opinion of Counsel stating that the proposed transaction and such supplemental indenture comply with this Indenture. This Section 10.02(a) will not prohibit a merger between Subsidiary Guarantors or a merger between the Company and a
Subsidiary Guarantor. 
  
 (b) In the event of a sale or other
disposition of all or substantially all of the assets of any Subsidiary Guarantor or a sale or other disposition of all of the Capital Stock of such Subsidiary Guarantor, in any case by way of merger, consolidation or otherwise, then such Subsidiary
Guarantor (in the event of a sale or other disposition, by way of such a merger, consolidation or otherwise, of all of the Capital Stock of such Subsidiary Guarantor) or the Person acquiring the assets (in the event of a sale or other disposition of
all or substantially all of the assets of such Subsidiary Guarantor) will be released and relieved of any obligations 

  

 56 

 
under its Guarantees; provided that in the event such sale or disposition constitutes an Asset Sale, the Net Available Proceeds of such sale or other
disposition are applied in accordance with the provisions of this Indenture described under Section 4.11. 
  
 SECTION 10.03. Addition of Subsidiary Guarantors. (a) The Company agrees to cause each domestic Subsidiary that shall become a Restricted
Subsidiary after the Issue Date and that guarantees any other Indebtedness of the Company or a Subsidiary Guarantor in excess of a De Minimis Guaranteed Amount to execute and deliver a supplemental indenture pursuant to which such Restricted
Subsidiary shall guarantee the payment of the Securities pursuant to the terms hereof within 180 days after the later of (i) the date that Restricted Subsidiary becomes a domestic Restricted Subsidiary and (ii) the date that Restricted Subsidiary
guarantees such other Indebtedness; provided that no guarantee shall be required if the Restricted Subsidiary merges into the Company or an existing Subsidiary Guarantor and the surviving entity remains a Subsidiary Guarantor. 
  
 (b) Any Person that was not a Subsidiary Guarantor on the Issue Date may
become a Subsidiary Guarantor by executing and delivering to the Trustee (i) a supplemental indenture in form and substance satisfactory to the Trustee, which subjects such Person to the provisions (including the representations and warranties) of
this Indenture as a Subsidiary Guarantor and (ii) an Opinion of Counsel and Officers’ Certificate to the effect that such supplemental indenture has been duly authorized and executed by such Person and constitutes the legal, valid and binding
obligation of such Person (subject to such customary exceptions concerning creditors’ rights and equitable principles as may be acceptable to the Trustee in its discretion and provided that no opinion need be rendered concerning the
enforceability of the Guarantee). 
  
 SECTION 10.04. Release of

in a pro rata amount based on the Adjusted Net Assets of each Subsidiary Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by the Funding Guarantor in discharging the Company’s obligations with respect
to the Securities or any other Subsidiary Guarantor’s obligations with respect to the Guarantee.

 (i) Except as
permitted by the following paragraphs (ii), (iii) and (iv), until the expiration of the applicable holding period with respect to the Securities set forth in Rule 144(k) of the Securities Act, each Security certificate evidencing the Restricted

 THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933 (THE “SECURITIES
ACT”), AND THIS SECURITY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THIS SECURITY IS HEREBY NOTIFIED THAT THE SELLER OF THIS SECURITY MAY BE
RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. 
  
 THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) THIS NOTE MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I)
THE COMPANY, (II) IN THE UNITED STATES TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (III) OUTSIDE THE
UNITED STATES IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER THE SECURITIES ACT, (IV) PURSUANT TO EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE) OR (V) PURSUANT TO AN EFFECTIVE

PURCHASER OF THIS SECURITY FROM IT OF THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE. 
  

 A-4 

 (ii) Upon any sale or transfer of a Transfer Restricted Security (including any Transfer
Restricted Security represented by a Restricted Global Security) pursuant to Rule 144 under the Securities Act, the Registrar shall permit the transferee thereof to exchange such Transfer Restricted Security for a certificated Security that does not
bear the legend set forth above and rescind any restriction on the transfer of such Transfer Restricted Security, if the transferor thereof certifies in writing to the Registrar that such sale or transfer was made in reliance on Rule 144 (such
certification to be in the form set forth on the reverse of the Security). 
  
 (iii) After a transfer of any Initial Securities or Private Exchange Securities pursuant to and during the period of the effectiveness of a Shelf Registration Statement with respect to such Initial Securities or
Private Exchange Securities, as the case may be, all requirements pertaining to legends on such Initial Security or such Private Exchange Security will cease to apply, the requirements requiring any such Initial Security or such Private Exchange
Security issued to certain Holders be issued in global form will cease to apply, and a certificated Initial Security or Private Exchange Security or an Initial Security or Private Exchange Security in global form, in each case without restrictive
transfer legends, will be available to the transferee of the Holder of such Initial Securities or Private Exchange Securities upon exchange of such transferring Holder’s certificated Initial Security or Private Exchange Security or directions
to transfer such Holder’s interest in the Global Security, as applicable. 
  
 (iv) Upon the consummation of a Registered Exchange Offer with respect to the Initial Securities, all requirements pertaining to such
Initial Securities that Initial Securities issued to certain Holders be issued in global form will still apply with respect to Holders of such Initial Securities that do not exchange their Initial Securities, and Exchange Securities in certificated
or global form will be available to Holders that exchange such Initial Securities in such Registered Exchange Offer. 
  
 (v) Upon the consummation of a Private Exchange with respect to the Initial Securities, all requirements pertaining to such Initial
Securities that Initial Securities issued to certain Holders be issued in global form will still apply with respect to Holders of such Initial Securities that do not exchange their Initial Securities, and Private Exchange Securities in global form
with the global securities legend and the Restricted Securities Legend set forth in Exhibit 1 hereto will be available to Holders that exchange such Initial Securities in such Private Exchange. 
  
 (c) Cancellation or Adjustment of Global Security. At such time as all
beneficial interests in a Global Security have either been exchanged for certificated Securities, redeemed, purchased or canceled, such Global Security shall be returned to the Depository for cancelation or retained and canceled by the Trustee. At
any time prior to such cancelation, if any beneficial interest in a Global Security is exchanged for certificated Securities, redeemed, purchased or canceled, the principal amount of Securities represented by such Global Security shall be reduced
and an adjustment shall be made on the books and records of the Trustee (if it is 

  

 A-5 

 
then the Securities Custodian for such Global Security) with respect to such Global Security, by the Trustee or the Securities Custodian, to reflect such
reduction.

registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate certificated Securities and Global Securities at the Registrar’s or co-registrar’s request.

transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax, assessments, or similar governmental charge payable in connection therewith (other than any such transfer taxes, assessments or similar
governmental charge payable upon exchange or transfer pursuant to Sections 3.06 and 4.16 of the Indenture). 
  
 (iii) The Registrar or co-registrar shall not be required to register the transfer of or exchange of any Security for a period beginning
15 Business Days before the mailing of a notice of an offer to repurchase or redeem Securities or 15 Business Days before an interest payment date. 
  
 (iv) Prior to the due presentation for registration of transfer of any Security, the Company, the Trustee, the Paying Agent, the Registrar
or any co-registrar may deem and treat the person in whose name a Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of and interest on such Security and for all other purposes whatsoever,
whether or not such Security is overdue, and none of the Company, the Trustee, the Paying Agent, the Registrar or any co-registrar shall be affected by notice to the contrary. 
  
 (v) All Securities issued upon any transfer or exchange pursuant to the terms of this Indenture shall
evidence the same debt and shall be entitled to the same benefits under this Indenture as the Securities surrendered upon such transfer or exchange. 
  
 (e) No Obligation of the Trustee. 
  
 (i) The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Security, Agent Member or other Person with
respect to the accuracy of the records of the Depository or its nominee or of any Agent Member, with respect to any ownership interest in the Securities or with respect to the delivery to any Agent Member, beneficial owner or other Person (other

through the Depository subject to the applicable rules and procedures of the Depository. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its Agent Member and any beneficial
owners. 
  

 A-6 

 (ii) The Trustee shall have no obligation or duty to monitor, determine or inquire as to

substantial compliance as to form with the express requirements hereof. 
  
 2.4 Certificated Securities.

Global Security deposited with the Depository or with the Trustee as Securities Custodian pursuant to Section 2.1 shall be transferred to the beneficial owners thereof in the form of certificated Securities in an aggregate principal amount equal to

 [REVERSE SIDE OF INITIAL SECURITY] 
  
 6.25% Senior Note due 2018 
  
 1. Interest 
  
 Chesapeake Energy Corporation, an Oklahoma 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; provided, however, that if a Registration Default (as defined in the Registration Rights
Agreement) occurs, additional interest will accrue on this Security at a rate of 0.25% per annum (increasing by an additional 0.25% per annum after each consecutive 90-day period that occurs after the date on which such Registration Default occurs
up to a maximum additional interest rate of 1.00%) from and including the date on which any such Registration Default shall occur to but excluding the date on which all Registration Defaults have been cured. The Company will pay interest
semiannually on January 15 and July 15 of each year, commencing January 15, 2006. 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 June 20, 2005. Interest will be
computed on the basis of a 360-day year of twelve 30-day months. 
  
 2. Method
of Payment 
  
 The Company will pay interest on the
Securities (except defaulted interest) to the Persons who are registered holders of Securities at the close of business on the January 1 or July 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 and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository
Trust Company. The Company will make all payments in respect of a certificated Security (including principal, premium and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments
on a certificated Security will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to
such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion). 
  
 3. Paying Agent and Registrar 
  
 Initially, The Bank of New York Trust Company, N.A., a national banking association (the “Trustee”), will act as Paying Agent and Registrar. The
Company may appoint and change any Paying Agent, Registrar or co-registrar without notice. The Company or any of its domestically incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or co-registrar. 
  

 B-3 

 4. Indenture 
  
 The Company issued the Securities under an Indenture dated as of June 20, 2005 (“Indenture”), among the Company, the Subsidiary Guarantors and
the Trustee. 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 Holders are referred to the Indenture and the Act for a
statement of those terms. 
  
 The Company shall be entitled,
subject to its compliance with Section 4.09(a) of the Indenture, to issue Additional Securities pursuant to Section 2.13 of the Indenture. The Initial Securities issued on the Issue Date, any Additional Securities and all Exchange Securities or
Private Exchange Securities issued in exchange therefor will be treated as a single class for all purposes under the Indenture. 
  
 5. Optional Redemption 
  
 The Securities may be redeemed at the option of the Company, in whole or from time to time in part, at any time on or after July 15, 2010, at the
redemption prices set forth below (expressed as a percentage of the principal amount of the Securities to be redeemed), together with accrued and unpaid interest on the Securities so redeemed to the redemption date, if redeemed during the 12-month
period commencing on July 15 of the years indicated below: 
  

			
	 Year

	  	Redemption
Price

	 2010
	  	103.125%
	 2011
	  	102.083%
	 2012
	  	101.042%
	 2013 and thereafter
	  	100.000%

  
 Any redemption
pursuant to this paragraph 5 shall be made, to the extent applicable, pursuant to the provisions of Sections 3.01 through 3.06 of the Indenture. 
  
 6. Equity Offering Redemption 
  
 In the event the Company consummates one or more Equity Offerings on or prior to July 15, 2008, the Company may redeem, in its sole discretion, up to 35%
of the aggregate principal amount of the Securities (which includes Additional Securities, if any) with all or a portion of the aggregate net proceeds received by the Company from any such Equity Offering or Equity Offerings at a redemption price of
106.25% of the aggregate principal amount of the Securities so redeemed, plus accrued and unpaid interest on the Securities so redeemed to the redemption date; provided, however, that (i) the date of any such redemption occurs within
the 120-day period after the Equity Offering in respect of which such redemption is made and (ii) following each such redemption, at least 65% of the aggregate principal amount of the Securities (which includes Additional Securities, if any) remains
outstanding. Any redemption pursuant to this paragraph 6 shall be made, to the extent applicable, pursuant to the provisions of Sections 3.01 through 3.06 of the Indenture. 
  

 B-4 

 7. Make-Whole Price Redemption 
  
 At any time prior to July 15, 2010, the Company may, at its option, redeem all or any portion of the Securities at the
“Make-Whole Price” (as defined in the Indenture) plus accrued and unpaid interest on the Securities so redeemed to the date of redemption. Any redemption pursuant to this paragraph 7 shall be made, to the extent applicable, pursuant to the
provisions of Sections 3.01 through 3.06 of the Indenture. 
  
 8. Notice of
Redemption 
  
 Notice of redemption will be mailed to the
Holder’s registered address at least 30 days but not more than 60 days before the redemption date to each Holder of Securities to be redeemed. If less than all Securities are to be redeemed, the Trustee shall select pro rata, by lot or, if the
Securities are listed on any securities exchange, by any other method that the Trustee considers fair and appropriate and that complies with the requirements of such exchange, the Securities to be redeemed in multiples of $1,000; provided,
however, that no Securities with a principal amount of $1,000 or less will be redeemed in part. Securities in denominations larger than $1,000 may be redeemed in part. On and after the redemption date, interest ceases to accrue on Securities
or portions of them called for redemption (unless the Company shall default in the payment of the redemption price or accrued interest). 
  
 9. Change of Control Offer 
  
 In the event of a Change of Control Triggering Event, the Company shall be required to make an offer to purchase all or any portion of each Holder’s
Securities, at 101% of the principal amount thereof, plus accrued and unpaid interest to the date of purchase. 
  
 10. Net Proceeds Offer 
  
 In the event of certain Asset Sales (and Sale/Leaseback Transactions), the Company may be required to make a Net Proceeds Offer to purchase all or any portion of each Holder’s Securities, at 100% of the principal amount thereof, plus
accrued and unpaid interest to the Net Proceeds Payment Date. 
  
 11.
Restrictive Covenants 
  
 The Indenture imposes certain
limitations on, among other things, the ability of the Company to merge or consolidate with any other Person or sell, lease or otherwise transfer all or substantially all of its properties or assets, the ability of the Company or the Restricted
Subsidiaries to dispose of assets, to pay dividends and make certain other distributions and payments, to make certain investments or redeem, retire, repurchase or acquire for value shares of Capital Stock, to incur additional Indebtedness or incur
encumbrances against certain property and to enter into certain transactions with Affiliates, all subject to certain limitations described in the Indenture and some of which will cease to have effect, upon notice from the Company to the Trustee, if
the Company obtains an Investment Grade Rating and no Event of Default has occurred and is continuing. 
  

 B-5 

 12. Ranking and Guarantees 
  
 The Securities are general senior unsecured obligations of the Company. The Company’s obligation to pay principal,
premium, if any, and interest with respect to the Securities is unconditionally guaranteed on a senior basis, jointly and severally, by the Subsidiary Guarantors pursuant to Article Ten of the Indenture. Certain limitations to the obligations of the
Subsidiary Guarantors are set forth in further detail in the Indenture. 
  
 13.
Denominations; Transfer; Exchange 
  
 The Securities are
in registered form without coupons in denominations of $1,000 principal amount and whole multiples of $1,000. A Holder may transfer or exchange Securities in accordance with the Indenture. The 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 Registrar need not register the transfer of or exchange of 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 Business Days before the mailing of a notice of an offer to repurchase or redeem Securities or 15 Business Days before an
interest payment date. 
  
 14. Persons Deemed Owners 
  
 The registered Holder of this Security may be treated as the owner of it for
all purposes. 
  
 15. 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, Holders entitled to the money must look only to the Company and not to the
Trustee for payment. 
  
 16. 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 Securities for the payment of principal and interest on the Securities to redemption or maturity, as
the case may be. 
  
 17. Amendment, Supplement, Waiver 
  
 Subject to certain exceptions, the Indenture or the Securities may be
amended or supplemented with the consent of the Holders of at least a majority of the outstanding principal amount of the Securities, and any past default or noncompliance with any provision may be waived with the consent of the Holders of a
majority in principal amount of the Securities. Without the consent of any Holder, the Company may amend or supplement the Indenture or the Securities to, among other things, cure any ambiguity, defect or inconsistency or to make any change that
does not adversely affect the rights of any Holder in any material respect. 
  

 B-6 

 18. Successor Corporation 
  
 When a successor corporation assumes all the obligations of its predecessor under the Securities and the Indenture, the
predecessor corporation will be released from those obligations. 
  
 19.
Defaults and Remedies 
  
 An Event of Default generally
is: default by the Company or any Subsidiary Guarantor for 30 days in payment of interest on the Securities; default by the Company or any Subsidiary Guarantor in payment of principal of, or premium, if any, on the Securities; default by the Company
or any Subsidiary Guarantor in the deposit of any optional redemption or repurchase payment when due and payable; defaults resulting in acceleration prior to maturity of certain other Indebtedness or resulting from payment defaults under certain
other Indebtedness; failure by the Company or any Subsidiary Guarantor for 45 days after notice to comply with any of its other agreements in the Indenture; certain final judgments against the Company or Subsidiaries; a failure of any Guarantee of a
Subsidiary Guarantor to be in full force and effect or denial by any Subsidiary Guarantor of its obligations with respect thereto; and certain events of bankruptcy or insolvency. Subject to certain limitations in the Indenture, if an Event of
Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Securities may declare all the Securities to be due and payable immediately, except that in the case of an Event of Default
arising from certain events of bankruptcy, insolvency or reorganization, all outstanding Securities shall become due and payable immediately without further action or notice. Holders may not enforce the Indenture or the Securities except as provided
in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. 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 Company must furnish an annual compliance certificate to the Trustee. 
  
 20. Trustee Dealings with Company and Subsidiary Guarantors 
  
 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 the
Company, the Subsidiary Guarantors or their respective Subsidiaries or Affiliates with the same rights it would have if it were not Trustee. 
  
 21. No Recourse Against Others 
  
 A director, officer, employee or stockholder, as such, of the Company, any Subsidiary Guarantor or the Trustee shall not have any liability for any
obligations of the Company, any Subsidiary Guarantor or the Trustee under the Securities 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 waives and
releases all such liability. The waiver and release are part of the consideration for the issue of the Security. 
  
 22. Authentication 
  
 This Security shall not be valid until the Trustee or an authenticating agent signs the certificate of authentication on the other side of this Security.

  

 B-7 

 23. Abbreviations 
  
 Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (=tenants in common), TEN ENT (=tenants by the entireties),
JT TEN (=joint tenants with right of survivorship and not as tenants in common), CUST (=Custodian), and U/G/M/A (=Uniform Gifts to Minors Act). 
  
 24. CUSIP Numbers 
  
 Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company will cause CUSIP numbers to be
printed on the Securities as a convenience to Holders of the Securities. No representation is made as to the accuracy of such numbers as printed on the Securities and reliance may be placed only on the other identification numbers printed hereon.

  
 25. Holders’ Compliance with Registration Rights Agreement

  
 Each Holder of this Security, by acceptance hereof,
acknowledges and agrees to the provisions of the Registration Rights Agreement, including the obligations of the Holders with respect to a registration and the indemnification of the Company to the extent provided therein. 
  
 26. Governing Law 
  
 THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING
EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY, EXCEPT TO THE EXTENT THAT THE LAWS OF THE STATE OF NEW YORK WOULD REQUIRE THE APPLICATION OF THE
LAWS OF ANOTHER JURISDICTION REGARDING THE VALIDITY OF THE SECURITIES.

 [FORM OF REVERSE SIDE OF EXCHANGE SECURITY 
 OR PRIVATE EXCHANGE SECURITY] 
  
 6.25% Senior Note due 2018 
  
 1. Interest

  
 Chesapeake Energy Corporation, an Oklahoma 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;
provided, however, that if a Registration Default (as defined in the Registration Rights Agreement) occurs, additional interest will accrue on this Security at a rate of 0.25% per annum (increasing by an additional 0.25% per annum
after each consecutive 90-day period that occurs after the date on which such Registration Default occurs up to a maximum additional interest rate of 1.00%) from and including the date on which any such Registration Default shall occur to but
excluding the date on which all Registration Defaults have been cured.** The Company will pay interest semiannually on January 15 and July 15 of each year, commencing January 15, 2006. 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 June 20, 2005. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 
  
 2. Method of Payment 
  
 The Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered holders of Securities at the close of
business on the January 1 or July 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 and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Company will make all payments in respect of a certificated Security (including
principal, premium and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on a certificated Security will be made 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). 
  

	**	Insert if at the date of issuance of the Exchange Security or Private Exchange Security (as the case may be) any Registration Default has occurred with respect to the related
Initial Securities during the interest period in which such date of issuance occurs.

co-registrar. 
  
 4. Indenture 
  
 The Company issued the Securities under an Indenture dated as of June 20,
2005 (“Indenture”), among the Company, the Subsidiary Guarantors and the Trustee. 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

such terms, and Holders are referred to the Indenture and the Act for a statement of those terms. 
  
 The Company shall be entitled, subject to its compliance with Section 4.09(a) of the Indenture, to issue Additional Securities pursuant to Section 2.13 of
the Indenture. The Initial Securities issued on the Issue Date, any Additional Securities and all Exchange Securities or Private Exchange Securities issued in exchange therefor will be treated as a single class for all purposes under the Indenture.

  
 5. Optional Redemption

made, to the extent applicable, pursuant to the provisions of Sections 3.01 through 3.06 of the Indenture. 
  
 8. Notice of Redemption 
  
 Notice of redemption will be mailed to the Holder’s registered address at least 30 days but not more than 60 days before the redemption date to each Holder of Securities to be redeemed. If less than all Securities are to be redeemed,
the Trustee shall select pro rata, by lot or, if the Securities are listed on any securities exchange, by any other method that the Trustee considers fair and appropriate and that complies with the requirements of such exchange, the Securities to be
redeemed in multiples of $1,000; provided, however, that no Securities with a principal amount of $1,000 or less will be redeemed in part. Securities in denominations larger than $1,000 may be redeemed in part. On and after the
redemption date, interest ceases to accrue on Securities or portions of them called for redemption (unless the Company shall default in the payment of the redemption price or accrued interest).

 11. Restrictive Covenants 
  
 The Indenture imposes certain limitations on, among other things, the ability of the Company to merge or consolidate with any other Person or sell, lease
or otherwise transfer all or substantially all of its properties or assets, the ability of the Company or the Restricted Subsidiaries to dispose of assets, to pay dividends and make certain other distributions and

encumbrances against certain property and to enter into certain transactions with Affiliates, all subject to certain limitations described in the Indenture and some of which will cease to have effect if the Company obtains an Investment Grade Rating
and no Event of Default has occurred and is continuing. 
  
 12. Ranking and
Guarantees 
  
 The Securities are general senior unsecured
obligations of the Company. The Company’s obligation to pay principal, premium, if any, and interest with respect to the Securities is unconditionally guaranteed on a senior basis, jointly and severally, by the Subsidiary Guarantors pursuant to
Article Ten of the Indenture. Certain limitations to the obligations of the Subsidiary Guarantors are set forth in further detail in the Indenture. 
  
 13. Denominations; Transfer; Exchange 
  
 The Securities are in registered form without coupons in denominations of $1,000 principal amount and whole multiples of $1,000. A Holder may transfer or
exchange Securities in accordance with the Indenture. The 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
Registrar need not register the transfer of or exchange of 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
Business Days before the mailing of a notice of an offer to repurchase or redeem Securities or 15 Business Days before an interest payment date. 
  
 14. Persons Deemed Owners 
  
 The registered Holder of this Security may be treated as the owner of it for all purposes. 
  
 15. 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, Holders entitled to the money must look only to the Company and not to the Trustee for payment. 
  
 16. 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 Securities for the payment of principal and interest on the Securities to redemption or maturity, as
the case may be. 
  
 17. Amendment, Supplement, Waiver 
  
 Subject to certain exceptions, the Indenture or the Securities may be
amended or supplemented with the consent of the Holders of at least a majority of the outstanding principal amount of the Securities, and any past 

  

 C-6 

 
default or noncompliance with any provision may be waived with the consent of the Holders of a majority in principal amount of the Securities. Without the
consent of any Holder, the Company may amend or supplement the Indenture or the Securities to, among other things, cure any ambiguity, defect or inconsistency or to make any change that does not adversely affect the rights of any Holder in any
material respect. 
  
 18. Successor Corporation 
  
 When a successor corporation assumes all the obligations of its predecessor
under the Securities and the Indenture, the predecessor corporation will be released from those obligations. 
  
 19. Defaults and Remedies 
  
 An Event of Default generally is: default by the Company or any Subsidiary Guarantor for 30 days in payment of interest on the Securities; default by the Company or any Subsidiary Guarantor in payment of principal of, or premium, if any, on
the Securities; default by the Company or any Subsidiary Guarantor in the deposit of any optional redemption or repurchase payment when due and payable; defaults resulting in acceleration prior to maturity of certain other Indebtedness or resulting
from payment defaults under certain other Indebtedness; failure by the Company or any Subsidiary Guarantor for 45 days after notice to comply with any of its other agreements in the Indenture; certain final judgments against the Company or
Subsidiaries; a failure of any Guarantee of a Subsidiary Guarantor to be in full force and effect or denial by any Subsidiary Guarantor of its obligations with respect thereto; and certain events of bankruptcy or insolvency. Subject to certain
limitations in the Indenture, if an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Securities may declare all the Securities to be due and payable immediately, except
that in the case of an Event of Default arising from certain events of bankruptcy, insolvency or reorganization, all outstanding Securities shall become due and payable immediately without further action or notice. Holders may not enforce the
Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. 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 Company must furnish an annual compliance certificate to the Trustee. 
  
 20. Trustee Dealings with Company and Subsidiary Guarantors 
  
 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 the
Company, the Subsidiary Guarantors or their respective Subsidiaries or Affiliates with the same rights it would have if it were not Trustee. 
  
 21. No Recourse Against Others 
  
 A director, officer, employee or stockholder, as such, of the Company, any Subsidiary Guarantor or the Trustee shall not have any liability for any
obligations of the Company, any Subsidiary Guarantor or the Trustee under the Securities 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 waives and
releases all such liability. The waiver and release are part of the consideration for the issue of the Security.
