Eagle Rock: Inclement Weather Delays Production in East Tx.

Eagle Rock was notified by Tristream Energy, the owner and operator of the Eustace processing facility, that inclement weather in East Texas has caused delays in returning the plant to service. The Eustace facility processes the majority of the Partnership's East Texas oil and gas production, which remains shut-in at this time.

Eagle Rock previously announced on December 20, 2010 that its East Texas oil and gas production would be shut-in until mid-February 2011, based on estimates provided by Tristream at that time. Tristream now expects to restart the plant within the coming weeks. Eagle Rock will provide further updates related to its East Texas oil and gas production as they become available.
