ECA Marcellus Trust I Announces Quarterly Distribution

ECA MARCELLUS TRUST I (NYSE: ECT) announced today that its distribution for the quarter ended December 31, 2010 will be $.500 per unit, which is expected to be distributed on or before February 28, 2011 to holders of record as of the close of business on February 14, 2011. The Trust was formed by Energy Corporation of America ("ECA") to own royalty interests in natural gas properties owned by ECA in the Marcellus Shale formation in Greene County, Pennsylvania, and is entitled to receive certain amounts of the proceeds attributable to ECA’s interest in the sale of production from the properties. As described in the Trust's filings, the amount of the quarterly distributions are expected to fluctuate from quarter to quarter, depending on the proceeds received by the Trust as a result of production and natural gas prices and the amount of the Trust's administrative expenses, among other factors. Although there is no assurance of any minimum distribution in any quarterly period, during the subordination period (as described in the Trust's filings), holders of Common Units will be entitled to receive an amount equal to the "Subordination Threshold" (which varies from quarter to quarter) prior to any distribution being made for that quarter to ECA as the holder of the Subordinated Units. If the amount available for distribution in any quarterly period is sufficient to distribute an amount equal to the Subordination Threshold to the holders of all units (including the Subordinated Units), any additional balance is distributed to holders of all units, up to the amount of the Incentive Threshold for the quarter. All amounts, if any, in excess of the Incentive Threshold for the quarter, are payable to ECA until it has been reimbursed for certain expenses, after which holders of the units will become entitled to receive 50% of any amount in excess of the Incentive Threshold for the quarter.
