[REVERSE SIDE OF NOTE]

4.875% Senior Note due 2022

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 Note at the rate per annum shown above. The Company shall pay interest semiannually on April 15 and October 15 of each year, commencing October 15, 2014³. Interest on the Note shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from April 24, 2014⁴. Interest shall be computed on the basis of a 360-day year consisting of twelve 30-day months.

The Company shall pay interest on the Notes (except defaulted interest) to the Persons who are registered holders of Notes at the close of business on the April 1 or October 1 next preceding the interest payment date even if Notes are canceled after the record date and on or before the interest payment date. Holders must surrender Notes to a Paying Agent to collect principal payments. The Company shall 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 Notes represented by a Global Security (including principal, premium and interest) shall be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Company shall make all payments in respect of a certificated Note (including principal, premium and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on a certificated Note shall 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).

If any interest payment date, Maturity Date or redemption date falls on a day that is not a Business Day, the applicable payment to be made on such payment date will be made on the next Business Day with the same force and effect as if made on the relevant interest payment date, Maturity Date or redemption date. No interest will accrue on such payment for the period from and after the applicable interest payment date, Maturity Date or redemption date.

The Company issued the Notes under an Indenture dated as of April 24, 2014, among the Company, the Subsidiary Guarantors and the Trustee, as supplemented by that Second Supplemental Indenture dated as of April 24, 2014, among the Company, the Subsidiary Guarantors and the Trustee (as so supplemented, the “Indenture”). The terms of the Notes

A-3

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 Notes 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 to issue Additional Notes pursuant to Section 2.03 of the Indenture. The Notes issued on the Issue Date and any Additional Notes shall be treated as a single series for all purposes under the Indenture.

Except as set forth below, the Company shall not be entitled to redeem the Notes prior to April 15, 2017.

At any time prior to April 15, 2017, the Company shall be entitled at its option to redeem the Notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus the Make-Whole Premium as of, and accrued and unpaid interest, if any, to the redemption date (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date). Any redemption pursuant to this paragraph 4 shall be made, to the extent applicable, pursuant to the provisions of Sections 3.02 through 3.07 of the Indenture.

The Trustee shall have no responsibility or obligation whatsoever to calculate the Make-Whole Premium in connection with any redemption hereunder. Such responsibility shall be solely that of the Company.

For the purposes of this paragraph 4, the following terms shall have the meaning indicated:

“Adjusted Treasury Rate” means, with respect to any redemption date, the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published Federal Reserve Statistical Release H.15 (519) or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System (or, if such release (or any successor release) is not published, any publicly available source of similar market data) and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after April 15, 2017, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month), calculated on the third Business Day immediately preceding the redemption date, plus 50 basis points.

“Comparable Treasury Issue” means the United States Treasury security selected by the Company as having a maturity comparable to the remaining term of the Notes from the redemption date to April 15, 2017 that would be utilized, at the time of selection and in

A-4

accordance with customary financial practice, in pricing new issues of corporate debt securities of a maturity most nearly equal to April 15, 2017.

“Make-Whole Premium” means with respect to a Note at any redemption date, the excess of (i) the present value at such redemption date of (A) the redemption price of such Note on April 15, 2017 (such redemption price being described in paragraph 5 below) exclusive of any accrued interest plus (B) all required remaining scheduled interest payments due on such Note through April 15, 2017 (but excluding accrued and unpaid interest to the redemption date), computed using a discount rate equal to the Adjusted Treasury Rate, over (ii) the principal amount of such Note on such redemption date.

At any time on or after April 15, 2017, the Company may redeem the Notes, in whole or in part, at its option, at the following redemption prices (expressed as percentages of the principal amount thereof), plus accrued and unpaid interest, if any, to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period (or, in the case of the period commencing April 15, 2020, such 12-month period and thereafter) commencing on April 15 of the years set forth below:

Any redemption pursuant to this paragraph 5 shall be made, to the extent applicable, pursuant to the provisions of Sections 3.02 through 3.07 of the Indenture.

At least 30 days but not more than 60 days before a redemption date, the Company shall mail a notice of redemption by first class mail (or otherwise give such notice in accordance with the Base Indenture) to each Holder of Notes to be redeemed at such Holder’s registered address. If less than all of the Notes are redeemed at any time, the Trustee shall select the Notes to be redeemed on a pro rata basis or by lot, in each case, in accordance with the procedures of the Depositary, or, if the Notes are listed on any securities exchange, by any other method that complies with the requirements of such exchange; provided, however, that no Notes with a principal amount of $1,000 or less shall be redeemed in part. Unless the Company defaults in payment of the applicable redemption price, interest on the Notes to be redeemed shall cease to accrue on the applicable redemption date, whether or not such Notes are presented for payment.

A-5

In the event of certain Sale/Leaseback Transactions, the Company may be required to make a Net Proceeds Offer to purchase all or any portion of each Holder’s Notes, at 100% of the principal amount thereof, plus accrued and unpaid interest to the Net Proceeds Payment Date.

The Indenture imposes certain limitations on, among other things, the ability of the Company to merge or consolidate with any other Person or sell and lease back certain of its properties or assets and the ability of the Company or the Subsidiaries to incur encumbrances securing funded debt against certain property, all subject to certain limitations described in the Indenture.

The Notes are general senior unsecured obligations of the Company. The Company’s obligation to pay principal, premium, if any, and interest with respect to the Notes 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.

The Notes are in registered form without coupons in denominations of $2,000 principal amount and integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes 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 Notes selected for redemption (except, in the case of a Note to be redeemed in part, the portion of the Note not to be redeemed) or any Notes for a period of 15 Business Days before the mailing of a notice of an offer to repurchase or redeem Notes or 15 Business Days before an interest payment date.

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

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.

Subject to certain conditions, the Company at any time shall be entitled to terminate some or all of its obligations under the Notes and the Indenture if the Company deposits with the

A-6

Trustee money or U.S. Government Securities for the payment of principal and interest on the Notes to redemption or maturity, as the case may be.

The amendment, supplement and waiver provisions are set forth in the Indenture. Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least a majority of the outstanding principal amount of the Notes, 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 Notes. Without the consent of any Holder, the Company may amend or supplement the Indenture or the Notes 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.

When a successor obligor assumes all the obligations of its predecessor under the Notes and the Indenture, the predecessor obligor shall be released from those obligations.

The defaults, events of default and remedies provisions are set forth in the Indenture. An Event of Default generally is: default by the Company or any Subsidiary Guarantor for 30 days in payment of interest on the Notes; default by the Company or any Subsidiary Guarantor in payment of principal of, or premium, if any, on the Notes; 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 60 days after notice to comply with any of its other agreements in the Indenture; 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 Notes may declare all the Notes 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 Notes shall become due and payable immediately without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the Notes may direct the Trustee in its exercise of any trust or power. The Company must furnish an annual compliance certificate to the Trustee.

The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Company, the Subsidiary Guarantors or their respective Subsidiaries or Affiliates with the same rights it would have if it were not Trustee.

A-7

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 Notes or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issue of this Note.

This Note shall not be valid until the Trustee or an authenticating agent signs the certificate of authentication on the other side of this Note.

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).

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company shall cause CUSIP numbers to be printed on the Notes as a convenience to Holders of the Notes. No representation is made as to the accuracy of such numbers as printed on the Notes and reliance may be placed only on the other identification numbers printed hereon.

THIS NOTE 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 NOTES.
