March 31, 2012

During the three month periods ended March 31, 2012 and 2011, the Company recognized approximately $1.2 million and $0.2 million, respectively, of revenues from Wylie Bice Trucking, LLC (“WBT”), whose owner is also 33% member in RM Resources. Of this total, approximately, $0.7 million and $0.04 million was included in accounts receivable as of March 31, 2012 and March 31, 2011, respectively. The revenue was generated as WBT injected flowback and production water into disposal wells owned by the Company.

During the three months ended March 31, 2012, the Company paid approximately $0.1 million in management fees to Rodne Consulting, LLC (“RC”), which is owned by Dean Rodne, a 33% member in the Company.

Litigation

The Company is involved in various legal proceedings that have arisen in the ordinary course of business. In the opinion of the Company’s management, all such proceedings are adequately covered by insurance or, if not so covered, should not materially result in any liability which would have a material adverse effect on the financial position, results of operations or cash flows of the Company.

On May 7, 2012, the Company’s members entered into an asset purchase agreement with QC Environmental Services, Inc. to sell the operating assets and rights of the Company for $31.7 million, plus potential additional consideration of $7.6 million if certain future operating and performance criteria are satisfied. On June 1, 2012, this sale was consummated for an adjusted purchase price of $31.4 million.

The North Dakota Industrial Commission (NDIC) Oil & Gas Division issued rule changes to the regulations established over drilling and production of oil which became effective April 1, 2012. In these rule changes, it was noted that rule # 43-02-03-19.5 prohibited the use of a reserve pit on most wells unless the wells drilled above the depth of 5,000 feet or for disposal wells in the Dakota Group formation.

One of RM Resources primary revenue streams is pit disposal water. The prohibition of disposal reserve pits at well sites will reduce the number of barrels being disposed. The Company does not expect a significant decline in disposal revenues as the wells are still viable for disposal of other types of disposal water such as production, chemical, and flow-back water.
