presents, GRANT, ASSIGN, TRANSFER and CONVEY unto the parties set forth below, hereinafter called the “Assignees”: 
 Karpman Enterprises, LP, a Texas limited partnership whose address is 2721 Manorwood Trail, Fort Worth, Texas 76109; 
 CDA Energy, LLC, a Texas limited liability company whose address is 1926 Stafford Rd., Grapevine, Texas 76015;

 1 

 The assignment of Overriding Royalty made herein is subject to the
following terms, conditions and provisions: 
  

	 	1.	For the purposes of calculating royalty payments, expenses and deductions, the Overriding Royalty shall be subject to the exact terms, conditions and provisions as
those found in the Leases, on a lease by lease basis. In other words, should the underlying or referenced lease provide for cost free royalty then the Overriding Royalty shall also be free and clear of all cost and expenses of exploration,
production, transportation and marketing, but shall bear its proportionate share of all gross production, severance, ad valorem and similar taxes. However, should the underlying referenced lease, on a lease by lease basis, be subject to deductions
for transportation, dehydration and marketing then the Overriding Royalty shall also be subject to the same deductions and proportionate share of all gross production, severance, ad valorem and similar taxes. 

 

	 	2.	If any of the Leases cover less than the full (100% of 8/8ths) interest in oil, gas and other minerals in all or any part of the lands and depths described therein, the
Overriding Royalty shall be proportionately reduced and paid to Assignee in the proportion that the interest covered by said Lease bears to the entire mineral estate; 

 

	 	3.	Assignor may, without the joinder of Assignee, pool and combine Assignee’s Overriding Royalty with other leases and lands in compliance with terms and conditions
of the Leases. 

  

	 	4.	The Overriding Royalty shall attach to any extension or renewals of the Leases and shall be calculated and paid in the same manner as the original reservation set forth
herein. Any lease acquired by Assignor, or its successors or assigns, within one (1) year of the termination of the Leases shall be deemed an extension or renewal lease for the purposes of this provision insofar as the renewal or extension
lease covers acreage transferred hereunder. 

 TO HAVE AND TO HOLD the above described overriding royalty,
together with all and singular the rights and appurtenances thereunto in anywise belonging unto Assignee, its successors and assigns forever; and Assignor does by these presents bind itself and its successors and assigns to warrant and forever
defend all and singular, the Leases unto Assignee, its successors and assigns, against every person whomsoever lawfully claiming or to claim the same or any part thereof by, through or under Assignor, but not otherwise.

 Energy & Exploration Partners, LLC whose address is P.O. Box 471428, Fort Worth, Texas
76147-1376, hereinafter called “Assignor”, for and inconsideration of the sum of TEN DOLLARS ($10.00) and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged by Assignor, does by these
presents, GRANT, ASSIGN, TRANSFER and CONVEY unto the parties set forth below, hereinafter called the “Assignees”: 
 Janice Boswell-Wueste, an individual, whose address is 2845 Manorwood Trl., Fort Worth, TX 76109; 
 Edward A. Wueste, an individual, whose address is 2845 Manorwood Trl., Fort Worth, TX 76109;

 Jason Roberts, an individual, whose address is 3005 Amherst Ave., Dallas, TX 75225. 
 an
overriding royalty interest (the “Overriding Royalty”), as described in Exhibit “A” attached hereto and made a part hereof for all purposes, in all oil, gas and other hydrocarbons produced, save and sold under the terms of the
Oil and Gas Leases described in Exhibit “A” (the “Lease(s)”) covering the lands described therein located in Laramie and Goshen Counties, Wyoming. 

  
 1 

 The assignment of Overriding Royalty made herein is subject to the
following terms, conditions and provisions: 
  

	 	1.	For the purposes of calculating royalty payments, expenses and deductions, the Overriding Royalty shall be subject to the exact terms, conditions and provisions as
those found in the Leases, on a lease by lease basis. In other words, should the underlying or referenced lease provide for cost free royalty then the Overriding Royalty shall also be free and clear of all cost and expenses of exploration,
production, transportation and marketing, but shall bear its proportionate share of all gross production, severance, ad valorem and similar taxes. However, should the underlying referenced lease, on a lease by lease basis, be subject to deductions
for transportation, dehydration and marketing then the Overriding Royalty shall also be subject to the same deductions and proportionate share of all gross production, severance, ad valorem and similar taxes. 

 

	 	2.	If any of the Leases cover less than the full (100% of 8/8ths) interest in oil, gas and other minerals in all or any part of the lands and depths described therein, the
Overriding Royalty shall be proportionately reduced and paid to Assignee in the proportion that the interest covered by said Lease bears to the entire mineral estate; 

 

	 	3.	Assignor may, without the joinder of Assignee, pool and combine Assignee’s Overriding Royalty with other leases and lands in compliance with terms and conditions
of the Leases. 

  

	 	4.	The Overriding Royalty shall attach to any extension or renewals of the Leases and shall be calculated and paid in the same manner as the original reservation set forth
herein. Any lease acquired by Assignor, or its successors or assigns, within one (1) year of the termination of the Leases shall be deemed an extension or renewal lease for the purposes of this provision insofar as the renewal or extension
lease covers acreage transferred hereunder. 

 TO HAVE AND TO HOLD the above described overriding royalty,
together with all and singular the rights and appurtenances thereunto in anywise belonging unto Assignee, its successors and assigns forever; and Assignor does by these presents bind itself and its successors and assigns to warrant and forever
defend all and singular, the Leases unto Assignee, its successors and assigns, against every person whomsoever lawfully claiming or to claim the same or any part thereof by, through or under Assignor, but not otherwise.
