Oxbow has surveyed the recently concluded 2009 borehole drilling activities. <br />The Northing and Easting coordinates and completion dates have been included on Exhibit 2.04- <br />E3, Item 9 - Methane Drainage Well Information. Please note that the updated Table also <br />includes the information for our TR-65 which includes information for the next three north <br />panels. <br />Item #2. As noted above, the revised Item 9 table also includes information for TR-65. The <br />TR-65 includes the Drawing 2.05-M1, sheet 6 of 6 information that shows LW-17-04 and LW- <br />17-01 A. We recognize that the concurrent review of TR-64 and TR-65 presents some challenges <br />with duplicate exhibits and information, but we have no remedy. <br />Item #3. The column headings for the Item 9 table are now provided on each page. <br />Item #4. Page 2.05-31 a, Paragraph E - Degasification Well Roads has been corrected as <br />requested. <br />Item #5. The USFS has requested information regarding whether our proposal is consistent <br />with conditions found in the Federal Coal Lease and whether Oxbow requires any relief from the <br />lease stipulations. In particular, they requested any information addressing operations on steep <br />slopes, geologic hazards or any additional information regarding drilling fluids. Attached is a <br />0 Page 1
