DATA ACQUISITION AGREEMENT 

This MASTER GEOPHYSICAL DATA ACQUISITION AGREEMENT (the “Master Agreement” or “Agreement”) is entered into this
     day of             , 2012; between                     , having
an office located in                      (hereinafter called “Company”) as well as, any legal entity which controls, is controlled
by or is under common control of the Company (the “Affiliate” or “Affiliates”) and Dawson Geophysical Company, a Texas corporation having offices in Midland, Texas (hereinafter called “Contractor”)
and its Affiliates. Company and Contractor may each be referred to herein as “Party” or collectively as “Parties”. 
 For and in consideration of the mutual covenants and promises of the Parties herein set forth, the Parties do hereby agree as follows: 

 

	1.	NATURE OF WORK 

 1.1 Contractor
shall conduct, for the benefit of Company, field geophysical data acquisition surveys (the “Surveys” or the “Work”) and related services in search of subsurface geological formations and structures favorable to the
accumulation of oil, gas and mineral deposits underlying those land areas designated, from time to time, by Company and accepted by Contractor, all in accordance with the terms and conditions of this Agreement, and the applicable Supplemental
Agreement. Contractor, if requested by Company, shall also provide data processing and/or interpretation services of and for the field data (“Data”) so acquired. 
 1.2 Such Survey(s) shall be conducted by one or more geophysical crews, as may be agreed upon by Contractor and Company, in such a manner and subject to the terms and conditions as set forth herein and in
the applicable Supplemental Agreement. If data processing services are requested, such services shall be done in Contractor’s data processing service centers in Midland, Texas; Houston, Texas; or Oklahoma City, Oklahoma. 

1.3 Nothing herein shall require Company to contract with Contractor or Contractor to accept assignments from Company to conduct Survey(s), except as may
be agreed upon, from time to time, in an appropriate Supplemental Agreement. 
  

	2.	SUPPLEMENTAL AGREEMENTS 

 2.1
(General) Whenever Company requests, and Contractor agrees, to conduct a Survey on behalf of Company, Contractor and Company shall enter into separate Supplemental Agreements for each separate Survey so undertaken, which Supplemental
Agreements shall be consecutively numbered for identification and shall provide the following: 
  

	 	(a)	The area(s) (state, county/parish, etc.) where the Survey(s) will be conducted (“Area of Operations”). 

 

	 	(b)	The approximate commencement date, if applicable, of the Survey(s) (“Commencement Date”). 

 

	 	(c)	The approximate period of time or number of miles (or square miles), if applicable, that will be required to complete the Survey(s). 

 

	 	(d)	The type of Survey(s) to be conducted. The equipment, instruments, personnel and other items (“Crew”) which will be required for the Survey(s).

  

	 	(e)	The parameters and other technical aspects of the Survey(s) and/or the processing of the Data acquired thereby. 

 

	 	(f)	The compensation to be paid Contractor for conducting the Survey(s) (“Compensation”). 

 

	 	(g)	Any other matters of a business, operational or technical nature as may be agreed by the Parties. 

2.2 (Crew Availability) It is recognized that difficulties in scheduling the activities of Contractor’s geophysical crews may result in
overlap or conflicts which prevent Contractor from providing geophysical Crews to conduct a particular Survey designated by Company at the time desired. Contractor shall make every reasonable effort to avoid such overlaps or conflicts in furnishing
Company a geophysical Crew for any designated Survey. In the event of any such conflict, however, Contractor shall notify Company promptly after such Survey has been requested by

 MASTER GEOPHYSICAL DATA ACQUISITION AGREEMENT 

 
Company that Contractor will be unable to conduct the Survey pursuant to Company’s time schedule. There shall then be, if feasible, at the election of Company, an agreed alternate date
between Company and Contractor that shall be a firm date for commencement of the Survey by Contractor. If no such alternate date can be agreed upon, then Contractor shall thereafter have no obligations hereunder in connection with not conducting
said Survey. 
 2.3 (Incorporation by Reference) Each Supplemental Agreement shall be incorporated herein by reference, and all terms and
provisions of this Agreement shall apply to each Supplemental Agreement unless, in any particular Supplemental Agreement, any of the terms and conditions hereof are eliminated or modified for purposes of that Supplemental Agreement by specific
reference to those terms and conditions hereof to be eliminated or modified. Any Supplemental Agreement incorporated herein and subject, thereby, to the terms and conditions hereof shall hereinafter be referred to as “Supplemental
Agreement” or “Supplement.” This Master Agreement and any applicable Supplemental Agreements may collectively be referred to as “this Agreement.” 
 2.4 (Conflicting Terms) In the event of a conflict between any of the terms and conditions of this Master Agreement and those of any Supplemental Agreement, the appropriate terms of this Agreement
shall govern and control, unless specifically provided to the contrary in any Supplemental Agreement, as provided above, or where a provision herein states that it is subject to or otherwise anticipates contrary terms of a Supplement. The fact that
additional terms or provisions appear in one or the other document shall not, in and of itself, create a conflict. 
  

	3.	PERSONNEL, EQUIPMENT AND SUPPLIES 

3.1 (General) The Contractor shall furnish, place in service and maintain, at its sole cost and expense, for the performance of Survey(s)
hereunder, the Crew more particularly described in Supplemental Agreements annexed hereto. 
 3.2 (Additional/Different Personnel or
Equipment) Changing operating conditions may require the Crew personnel and equipment set forth in said Supplemental Agreements to be increased, reduced or changed or the Area of Operations or the parameters of the Survey changed. Accordingly,
Contractor shall, when authorized by Company, furnish such auxiliary or additional personnel, equipment, supplies and services or make such other changes as may be required in connection therewith all as more particularly set forth and described in
the Supplemental Agreements or amendments thereto, which shall clearly set forth the additional compensation, if any, to be paid to the Contractor as a result of such changes. 

 

	4.	CONDUCT OF OPERATIONS 

 4.1
(Conduct of Operations by Contractor) In conducting operations hereunder, Contractor shall use its best efforts to conduct all operations hereunder in accordance with the terms and specifications of this Agreement (and those of the applicable
Supplemental Agreement) and in conformance with generally accepted practices of the geophysical data acquisition industry. In particular, Contractor agrees that, in conducting operations under the terms hereof it will:

which may be made by reason for the Work performed under the terms of this Agreement. 
  

	5.	PERMITS 

 5.1. (General)
Unless Company assumes the permitting responsibility under Clause 5.3 below, Contractor shall, at Company’s request and expense, obtain such permits, licenses and clearances (the “Land Entry Permits”). Company’s cost shall
include entry fees and damage payments as well as payments to governmental agents, per diem, if any, needed to secure such Land Entry Permits. Contractor will use its reasonable efforts to secure written Land Entry Permits from the person or persons
representing themselves to be owners or lessees of the areas involved. Contractor will not enter upon lands where Land Entry Permits have not been obtained by it (or represented by Company as having been obtained by it) unless otherwise directed, in
writing with full indemnification in favor of Contractor, at Company’s sole risk, by Company to do so. 
 5.2 (Permit Fees) In the
event it becomes necessary to pay for permission to enter upon any area connected with the Survey, Contractor will notify Company of such area involved and the fees required in order to obtain the Land Entry Permits and will proceed with the consent
of Company’s Representative. Company will reimburse Contractor the cost of all such Permits unless otherwise provided in the applicable Supplemental Agreement. 
 5.3 (Permits Obtained by Company) In the event Company assumes the responsibility for obtaining or supervising the obtaining of all or some Land Entry Permits from land owners, mineral owners,
appropriate governmental agencies, lessees, tenants, and all other persons having permissible interests in the land or its subsurface minerals, in the Area of Operations, as may be required in connection with all such Survey(s) to be performed by
Contractor under this Agreement, either by utilizing Company personnel or those of third party contractors (whether individuals, corporate or otherwise), Company shall have the obligations set forth in Clause 8.6 below and Contractor shall not be
responsible for any delays in its operations caused by (i) the inability of Company to acquire any Permit on a timely basis or (ii) onerous provisions contained in such Permits which impede or adversely affect the operations of Contractor
hereunder. Contractor shall be compensated during any such delays at the standby rate set forth in the applicable Supplement. If Company acquires Land Entry Permits, it will provide copies thereof to Contractor sufficiently in advance of operations
in order for Contractor to properly plan its operations.
