Atlas America, Inc. Files 10b5-1 Plan for Executive Officer

PHILADELPHIA, PA--(Marketwire - November 21, 2007) - Atlas America, Inc. (NASDAQ: ATLS) ("the Company") announced today that Edward E. Cohen, Chairman and Chief Executive Officer, has adopted a stock trading plan as part of a strategy for estate planning, asset diversification and liquidity. Under this plan, Mr. Cohen may sell up to 15,000 shares of the Company's common stock during each month of the plan, subject to the satisfaction of certain contingencies.

The trading plan was adopted in accordance with guidelines specified by the Securities and Exchange Commission's rule 10b5-1 under the Securities Exchange Act of 1934. Rule 10b5-1 allows corporate officers and directors to adopt written, prearranged stock trading plans when they do not have material, nonpublic information. Using these plans, insiders can gradually diversify their investment portfolios, spread stock trades out over an extended period of time to reduce any market impact and avoid concerns about whether they had material, nonpublic information when they sold their stock.

Sales under the plan may commence in November 2007 and will end in November 2009. If Mr. Cohen completes all planned sales of shares under his rule 10b5-1 plan, he would still beneficially own approximately 3.0 million shares of Atlas America's outstanding common stock, including exercisable stock options, shares held by family charitable trusts and members of Mr. Cohen's family, which represents 11.2 % of Atlas America's outstanding common stock as of September 30, 2007. In addition, Mr. Cohen will continue to hold units in Atlas Energy Resources, LLC, Atlas Pipeline Partners, L.P., and Atlas Pipeline Holdings, L.P.

In accordance with Mr. Cohen's trading plan, the sales will be under the direction of Mr. Cohen's broker. All transactions will be disclosed publicly through Form 144 and Form 4 filings with the Securities and Exchange Commission.
