[REVERSE SIDE OF NOTE]

RANGE RESOURCES CORPORATION

1. Indenture.

This is one of the Securities issued under an Indenture dated as of March 9, 2012 (as supplemented or amended from time to time, the “Indenture”), among the Company, the Subsidiary Guarantors party thereto and The Bank of New York Mellon Trust Company, N.A., as Trustee, which Securities have been designated by supplemental indenture thereto as the 5% Senior Subordinated Notes due 2022. Capitalized terms used herein are used as defined in the Indenture unless otherwise indicated. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture will control.

The Notes are general unsecured obligations of the Company. The Indenture provides for the initial issuance of $600,000,000 principal amount of Notes, but additional Notes may be issued pursuant to the Indenture, and the originally issued Notes and all such additional Notes vote together for all purposes as a single class.

2. Principal and Interest.

The Company promises to pay the principal of this Note on August 15, 2022.

The Company promises to pay interest on the principal amount of this Note on each interest payment date, as set forth on the face of this Note, at the rate of 5% per annum. Interest will be payable semiannually (to the holders of record of the Notes at the close of business on the February 1 and August 1 immediately preceding the relevant interest payment date) on each interest payment date, commencing August 15, 2012.

Interest on this Note will accrue from the most recent date to which interest has been paid on this Note (or, if there is no existing default in the payment of interest and if this Note is authenticated between a regular record date and the next interest payment date, from such interest payment date) or, if no interest has been paid on the Notes, from March 9, 2012. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

The Company will pay interest on overdue principal, premium, if any, and, to the extent lawful, interest at a rate per annum that is 1% in excess of 5%. Interest not paid when due and any interest on principal, premium or interest not paid when due will be paid to the Persons that are Holders on a special record date, which will be the close of business on the 15th day preceding the date fixed by the Company for the payment of such interest, whether or not such day is a Business Day. At least 15 days before a special record date, the Company will send to each Holder and to the Trustee a notice that sets forth the special record date, the payment date and the amount of interest to be paid.

A-4

3. Optional Redemption.

(a) Except as provided in paragraphs 3(b) and 3(c) below, the Notes are not redeemable at the Company’s option prior to February 15, 2017. From and after February 15, 2017, the Notes will be subject to redemption at the option of the Company, in whole or in part, upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest thereon to the applicable redemption date, if redeemed during the twelve-month period beginning on February 15 of the years indicated below:

(b) Prior to February 15, 2015 the Company may, at its option, on any one or more occasions, redeem up to 35% of the original aggregate principal amount of Notes at a redemption price equal to 105.000% of the principal amount thereof, plus accrued and unpaid interest, if any, thereon to the redemption date, with the net proceeds of sales of public Equity Interests of the Company; provided that at least 65% of the original aggregate principal amount of Notes remain outstanding immediately after the occurrence of such redemption; and provided, further, that any such redemption shall occur within 60 days after the date of the closing of the related sale of such Equity Interests.

(c) Prior to February 15, 2017, the Company may redeem all or, from time to time, any part of the Notes upon not less than 30 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount thereof plus the Make-Whole Premium plus accrued and unpaid interest, if any, to the redemption date.

“Make-Whole Premium” means, with respect to a Note at any redemption date, the excess of (A) the present value at such time of (1) the redemption price, excluding accrued interest, of such note at February 15, 2017, (as set forth in the table in paragraph 3(a) above) plus (2) all required interest payments, excluding accrued interest, due on such Note through February 15, 2017, computed using a discount rate equal to the Treasury Rate plus 50 basis points, over (B) the principal amount of such Note.

“Treasury Rate” means the yield to maturity at the time of computation of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 (519) which has become publicly available at least two Business Days prior to the redemption date (or, if such Statistical Release is no longer published, any publicly available source or similar market data)) most nearly equal to the period from the redemption date to February 15, 2017; provided, however, that if the period from the redemption date to February 15, 2017 is not equal to the constant maturity of a United States Treasury security for which a weekly average yield is given, the Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly average yields of

A-5

United States Treasury securities for which such yields are given, except that if the period from the redemption date to February 15, 2017 is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year shall be used.

If the optional redemption date is on or after an interest record date and on or before the related interest payment date, the accrued and unpaid interest, if any, will be paid to the Person in whose name the Note is registered at the close of business on such record date, and no additional interest will be payable to Holders whose Notes will be subject to redemption by the Company.

4. Mandatory Redemption.

Except as set forth in paragraph 5 below, the Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes.

5. Repurchase at Option of Holder.

(a) Upon the occurrence of a Change of Control, each Holder of Notes shall have the right to require the Company to repurchase all or any part (equal to $1,000 or an integral multiple thereof, and in a minimum amount of $1,000) of such Holder’s Notes subject to and as provided in the Indenture.

(b) If the Company or a Restricted Subsidiary consummates any Asset Sales permitted by the Indenture, when the aggregate amount of Excess Proceeds exceeds $10.0 million, the Company shall make an Asset Sale Offer to purchase the maximum principal amount of Notes and any other pari passu Indebtedness to which the Asset Sale Offer applies that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to, in the case of the Notes, 100% of the principal amount thereof, plus accrued and unpaid interest thereon to the date of purchase or, in the case of any pari passu Indebtedness, 100% of the principal amount thereof (or with respect to discount pari passu Indebtedness, the accreted value thereof) on the date of purchase, in each case, subject to and as provided in the Indenture.

6. Notice of Redemption. Notice of redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations larger than $1,000 may be redeemed in part but only in integral multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the redemption date interest will cease to accrue on the aggregate principal amount of the Notes called for redemption.

7. Registered Form; Denominations; Transfer; Exchange.

The Notes are in registered form without coupons in minimum denominations of $1,000 principal amount and any multiple of $1,000 in excess thereof. A Holder may register the transfer or exchange of Notes in accordance with the Indenture. The Trustee may require a Holder to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. Pursuant to the Indenture, there are certain periods during which the Trustee will not be required to issue, register the transfer of or exchange any Note or certain portions of a Note.

A-6

8. Persons Deemed Owners. The registered Holder of a Note shall be treated as its owner for all purposes.

9. Amendment, Supplement and Waiver. 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 in aggregate principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or the tender offer or exchange offer for, such Notes), and any existing Default or Event of Default under, or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes. Without the consent of any Holder of a Note, the Indenture or the Notes may be amended on supplemented to, among other things, cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to or in place of certificated Notes, to provide for the assumption of the Company’s obligations to Holders of the Notes in case of a merger or consolidation, to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights under the Indenture of any such Holder, or to comply with the requirements of the Commission in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act.

10. Defaults and Remedies. The Indenture provides that if an Event of Default (other than with respect to bankruptcy events) 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, and in the case of an Event of Default arising from certain events of bankruptcy or insolvency with respect to the Company, any Significant Subsidiary or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable without further action or notice. Holders of the Notes may not enforce the Indenture or the Notes except as provided in the Indenture.

11. Subordination. The Notes are subordinated to Senior Debt of the Company as provided in the Indenture. To the extent provided in the Indenture, Senior Debt must be paid before the Notes may be paid. The Company agrees, and each Holder by accepting a Note agrees, that the Indebtedness evidenced by the Notes, including, but not limited to, the payment of principal of, premium, if any, and interest on the Notes, and any other payment Obligation of the Company in respect of the Notes is subordinated in right of payment, to the extent and in the manner provided in the Indenture, to the prior payment in full in cash of all Senior Debt of the Company (whether outstanding on the date hereof or hereafter created, incurred, assumed or guaranteed) and authorizes the Trustee to give effect and appoints the Trustee as attorney-in-fact for such purpose.

12. Trustee Dealings with Company. The Indenture contains certain limitations on the rights of the Trustee, should it become a creditor of the Company, to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. The Trustee will be permitted to engage in other transactions; however, if it acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the Commission for permission to continue or resign.

A-7

13. No Recourse Against Others. No director, officer, employee, incorporator or stockholder of the Company, as such, shall have any liability for any obligations of the Company 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 of Notes, by accepting a Note, waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

14. Authentication.

This Note is not valid until the Trustee (or Authenticating Agent) signs the certificate of authentication on this Note.

15. Governing Law.

This Note shall be governed by, and construed in accordance with, the laws of the State of New York.

16. 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).

Exhibit B

Guarantee

Each of the Subsidiary Guarantors hereby, jointly and severally and unconditionally guarantees to each Holder of a Security authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, dated as of March 9, 2012, among Range Resources Corporation, a Delaware corporation (the “Company”), the Subsidiary Guarantors party thereto and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”) (as it may be amended or supplemented, the “Indenture”), the Securities or the obligations of the Company hereunder or thereunder, that: (a) the principal of, and premium, if any, and interest on, the Securities shall be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, and interest on premium and interest on, the Securities, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of any Securities or any of such other obligations, that same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Subsidiary Guarantors shall be jointly and severally obligated to pay the same immediately.

The obligations of the Subsidiary Guarantors to the Holders of Securities and to the Trustee pursuant to this Guarantee and the Indenture (including the subordination provisions thereof) are expressly set forth in Article 11 of the Indenture, and reference is hereby made to such Indenture for the precise terms of this Guarantee. The terms of Article 11 of the Indenture are incorporated herein by reference.

This is a continuing Guarantee and shall remain in full force and effect and shall be binding upon each of the Subsidiary Guarantors and its respective successors and assigns to the extent set forth in the Indenture until full and final payment of all of the Company’s Obligations under the Securities and the Indenture and shall inure to the benefit of the Trustee and the Holders of Securities and their successors and assigns and, in the event of any transfer or assignment of rights by any Holder of Securities or the Trustee, the rights and privileges herein conferred upon that party shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions hereof. Notwithstanding the foregoing, any Subsidiary Guarantor that satisfies the provisions of Section 11.04 of the Indenture shall be released of its obligations hereunder. This is a Guarantee of payment and not a, guarantee of collection.

This Guarantee shall not be valid or obligatory for any purpose until the certificate of authentication on the Security upon which this Guarantee is noted shall have been executed by the Trustee under the Indenture by the manual signature of one of its authorized officers.

For purposes hereof, each Subsidiary Guarantor’s liability will be that amount from time to time equal to the aggregate liability of such Subsidiary Guarantor hereunder but shall be limited to the lesser of (i) the aggregate amount of the obligations of the Company under the Securities and the Indenture

B-1

and (ii) the amount, if any, which would not have (A) rendered such Subsidiary Guarantor “insolvent” (as such term is defined in the federal Bankruptcy Code and in the Debtor and Creditor law of the State of New York) or (B) left it with unreasonably small capital at the time its Guarantee was entered into, after giving effect to the incurrence of existing Indebtedness immediately prior to such time; provided, that, it shall be a presumption in any lawsuit or other proceeding in which such Subsidiary Guarantor is a party that the amount guaranteed pursuant to its Guarantee is the amount set forth in clause (i) above unless any creditor, or representative of creditors of such Subsidiary Guarantor, or debtor in possession or trustee in bankruptcy of such Subsidiary Guarantor, otherwise proves in such a lawsuit that the aggregate liability of such Subsidiary Guarantor is limited to the amount set forth in clause (ii). The Indenture provides that, in making any determination as to the solvency or sufficiency of capital of a Subsidiary Guarantor in accordance with the previous sentence, the right of such Subsidiary Guarantor to contribution from other Subsidiary Guarantors and any other rights such Subsidiary Guarantor may have, contractual or otherwise, shall be taken into account.

Capitalized terms used herein have the same meanings given in the Indenture unless otherwise indicated.
