Note 1 — Organization

Carbon Natural Gas Company (“Carbon”), formerly known as St. Lawrence Seaway Corporation (“SLSC”), is an independent oil and gas company engaged in the exploration, development and production of oil and natural gas in the United States.  The Company was formed as the result of a merger with Nytis Exploration (USA) Inc. (“Nytis USA”) in February 2011 (see Note 3).  The Company’s business is comprised of the assets and properties of Nytis USA and its subsidiaries Nytis Exploration Company LLC (“Nytis LLC”) and Nytis Exploration of Pennsylvania LLC (“Nytis Pennsylvania”) which conduct the Company’s operations in the Appalachian and Illinois Basins.  Subsequent to the merger, the Company believed that the continued use of the name St. Lawrence Seaway Corporation might result in market confusion regarding the Company’s current planned operations and business objectives.  The Company believed the name “Carbon Natural Gas Company” was more descriptive of the business operations in which the Company engages.  This action was implemented by filing an Amended and Restated Certificate of Incorporation with the State of Delaware which become effective May 2, 2011. Collectively, SLSC, Carbon, Nytis USA, Nytis LLC and Nytis Pennsylvania are referred to as the Company.
