Gene Dubay, President and Chief Executive Officer of Atlas Pipeline stated, "With this sale and the previously announced Williams transaction, we will be paying down approximately $400 million of debt. We continue to work on other transactions which should generate additional cash and further de-lever our company. Concurrently, we are focusing on APL's core strengths which, in our opinion, will make the new, leaner APL a stronger provider of gathering and processing services in the Mid-Continent and in Appalachia, where our new alliance with Williams will allow us to accelerate our Marcellus initiatives."

The pending sale is expected to close during the second quarter of 2009 and is subject to Hart-Scott-Rodino approval and other customary closing conditions and traditional purchase price adjustments.

UBS Investment Bank acted as financial advisor to Atlas Pipeline in this transaction.
