The disclosures below apply to the contents of this presentation: On April 17, 2007, GeoResources, Inc. (“GEOI” or the “Company”) merged with Southern Bay Oil & Gas, L.P. (“Southern Bay”) and a subsidiary of Chandler Energy, LLC (“Chandler”), and acquired certain Chandler-associated oil and gas properties (collectively, the “Merger”). At the time of the Merger, the former Southern Bay partners received approximately 57% of the Company’s outstanding common stock. Although GEOI was the legal acquirer in the Merger, for financial reporting purposes the Merger was accounted for as a reverse acquisition of GEOI by Southern Bay. Therefore, any information prior to 2007 relates solely to Southern Bay. In connection with the Merger, officers and directors affiliated with Southern Bay and Chandler were appointed to most of our board seats and executive officer positions. Proved reserves, and estimates of discounted present values associated therewith (“PV-10”), as shown throughout this profile, are estimated by GEOI management as of 10/1/09 and based on NYMEX strip pricing at 9/30/09. The NYMEX oil strip used for the estimates ranged from $70.65 per BO for 2009 to $90.16 per BO for years 2017 and beyond. The NYMEX gas strip ranged from $4.83 per MCF for 2009 to $7.52 per MCF for years 2017 and beyond. Actual prices realized will likely vary materially from the NYMEX strip at 9/30/09. The company’s independent engineers are Cawley, Gillespie & Associates, Inc. and while they have not reviewed nor audited the reserves and economics presented herein, the company believes it has estimated reserves in a manner similar to external independent engineers. Non-proved reserve potential represents the company’s estimated reserve exposure associated with existing fields, acreage and prospects. These estimated reserves do not include certain exploratory objectives associated with proved undeveloped reserves or “work-in-progress”, which may result in additional prospects or drilling locations. Current SEC regulations do not recognize non-proved reserves. As used herein, EBITDAX is calculated as earnings before interest, income taxes, depreciation, depletion and amortization, and exploration expense and further includes impairments and hedge ineffectiveness and income or loss on derivative contracts. EBITDAX should not be considered as an alternative to net income (as an indicator of operating performance) or as an alternative to cash flow (as a measure of liquidity or ability to service debt obligations) and is not in accordance with, nor superior to, generally accepted accounting principles, but provides additional information for evaluation of our operating performance. Estimates of partnership reserves and values associated therewith do not include potential reversionary interests, if any. 3 Additional Disclosures |
