The Lessee,' using cement or other suitable plugging material approved by <br />the Little Snake Field Manager, shall plug the hole through the thickness of the coal beds <br />or mineral deposit(s) and through aquifers for a distance of at least 50 feet above and 50 <br />feet below the coal beds or mineral deposit(s) and aquifers or to the bottom of the drill <br />hole. A lesser cap or plug may be approved by the Little Snake Field Manager. Item A <br />illustrates the minimum requirements for plugging drill holes. <br />2. The requirements for submission of geologic and abandonment information provided in <br />Item B (attached) shall be followed. <br />3.

All drill holes will be geophysically logged with natural gamma, density, resistivity, and <br />caliper curves. <br />6.
