 Cautionary Statements  This presentation includes forward-looking statements. Forward-looking statements related to future events, such as expectations regarding our capital program, development plans, production rates, resource potential, transportation capacity, net present value and projected liquidity. These statements are not guarantees of future performance and actual outcomes may differ materially. Factors that could affect the Company's business include, but are not limited to: oil and gas prices, operating hazards, drilling risks, unsuccessful exploratory activities; unexpected cost increases; potential liability for remedial actions under existing or future environmental regulations; potential liability resulting from pending or future litigation; limited access to capital or significantly higher cost of capital related to illiquidity or uncertainty in the domestic or international financial markets; as well as changes in tax, environmental and other laws applicable to our business. Other factors that could cause actual results to differ materially from those described in the forward-looking statements include other economic, business, competitive and/or regulatory factors affecting our business generally as set forth in our filings with the Securities and Exchange Commission. Unless legally required, the Company undertakes no obligation to update publicly any forward-looking statements, whether as a result of new information, future events or otherwise. For filings reporting year-end 2014 reserves, the SEC permits the optional disclosure of probable and possible reserves.  The Company has elected not to report probable and possible reserves in its filings with the SEC.  We use the term “net risked resources” or “inventory” to describe the Company’s internal estimates of volumes of natural gas and oil that are not classified as proved reserves but are potentially recoverable through exploratory drilling or additional drilling or recovery techniques.  Estimates of unproved resources are by their nature more speculative than estimates of proved reserves and accordingly are subject to substantially greater risk of actually being realized by the Company.  Estimates of unproved resources may change significantly as development provides additional data, and actual quantities that are ultimately recovered may differ substantially from prior estimates.   14
