 Exhibit 4.2 

FIRST SUPPLEMENTAL INDENTURE 

FIRST SUPPLEMENTAL INDENTURE (this “Supplemental Indenture”), dated as of January 29, 2013, among Samson Resources Corporation,
a Delaware corporation (the “Guaranteeing Parent”), a direct parent company of Samson Investment Company (or its permitted successor), a Nevada corporation (the “Issuer”), the Issuer and Wells Fargo Bank, National Association, as
trustee under the Indenture referred to below (the “Trustee”). 
 WITNESSETH 

WHEREAS, the Issuer has heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of
February 8, 2012, providing for the issuance of 9.750% Senior Notes due 2020 (the “Notes”); 
 WHEREAS, the Indenture
provides that under certain circumstances the Guaranteeing Parent shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Parent shall unconditionally guarantee all of the Issuer’s Obligations under
the Notes and the Indenture on the terms and conditions set forth herein (the “Guarantee”); and 
 WHEREAS, pursuant to
Section 901 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture. 
 NOW, THEREFORE, in
consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Parent and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the
Notes as follows: 
 1. CAPITALIZED TERMS. Capitalized terms used herein without definition shall have the meanings assigned to them in the
Indenture. 
 2. AGREEMENT TO GUARANTEE. The Guaranteeing Parent hereby agrees to provide an unconditional Guarantee on the terms and
subject to the conditions set forth in the Note Guarantee and in the Indenture including but not limited to Article Twelve thereof. 
 3. NO
RECOURSE AGAINST OTHERS. No past, present or future director, officer, employee, incorporator, stockholder or agent of the Guaranteeing Parent, as such, shall have any liability for any obligations of the Issuer or any Guaranteeing Parent under the
Notes, any Guarantees, the Indenture or this Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the 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. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy. 

4. GOVERNING LAW. THIS SUPPLEMENTAL INDENTURE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. 

5. COUNTERPARTS. The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of
them together represent the same agreement. 
 6. EFFECT OF HEADINGS. The Section headings herein are for convenience only and shall not
affect the construction hereof. 
 7. THE TRUSTEE. The Trustee shall not be responsible in any manner whatsoever for or in respect of the
validity or sufficiency of this Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the Guaranteeing Parent and the Issuer. 







 IN WITNESS WHEREOF, the parties hereto have caused this Supplemental Indenture to be duly
executed as of the date first above written.
