| RE: | | Notice of Blackout Period |
| | | |
| Date: | | August 27, 2008 |
As you know, you may not buy or sell equity securities of Atlas during a specified period of time in each calendar quarter (the “Quarterly Blackout Period”). Atlas publicly released its second quarter 2008 earnings on August 7, 2008, and the Quarterly Blackout Period ended on August 12, 2008. The Quarterly Blackout Period will for the third quarter will begin on September 15, 2008 and will last until the second business day following the public release of Atlas’ third quarter 2008 earnings. You will be informed of the exact date on which the Quarterly Blackout Period for the third quarter will end.
Please note that the Quarterly Blackout Period for the third quarter is expected to overlap with — but may not necessarily end at the same time as — a separate blackout period for participants in the Atlas America, Inc. Investment Savings Plan (the “401(k) Plan”). As explained in the attached notice for the Atlas America, Inc. Investment Savings Plan, the blackout period for the 401(k) Plan is scheduled to begin on Monday, September 22, 2008 at 4:00 p.m. Eastern Time, and end during or before the week of November 14, 2008 (the “Plan Blackout Period”).
Even if you are not a participant in the 401(k) Plan, you will be prohibited from trading in equity securities of Atlas, other than exempt transactions, from September 15, 2008 until the expiration of the Quarterly Blackout Period for the third quarter or the expiration of the Plan Blackout Period, whichever is later.
Federal securities laws require us to provide this notice to you as a director or executive officer of Atlas.
If you participate in the 401(k) Plan, you will be prohibited from completing transactions relating to the 401(k) Plan during the Plan Blackout Period. During this period, you will further be prohibited from trading in equity securities of Atlas, outside of the context of the 401(k) Plan, if those securities were acquired in connection with your service or employment as a director or executive officer of Atlas. Finally, certain transactions are exempt from the prohibitions of both blackout periods — please contact me at (215) 546-5005 for further information or questions.

Any pending purchase or sale orders involving equity securities of Atlas that could be executed during a blackout period must be canceled, unless they are part of a written trading plan that has been cleared by Atlas or are otherwise exempt transactions. Please refer to our Code of Ethics and Insider Trading Policy for further information regarding investment in Atlas securities and remember that you are prohibited from buying, selling or recommending securities while you are aware of material, non-public information about the security or its issuer.
