Reportable Event

On September 29, 2004, Rocky Mountain Acquisition Corp. (“AcquisitionCo”), a subsidiary of Enterra Energy Trust, completed the acquisition of all of the issued and outstanding common shares of Rocky Mountain Energy Corp. ("Rocky").  The acquisition was completed by way of a plan of arrangement (the “Arrangement”). The transaction, including the assumption of Rocky debt, has been valued at approximately C$55 million.  As a result of this acquisition, Enterra has approximately 25 million trust units outstanding.

The Court of Queen's Bench of Alberta also approved the Arrangement on September 28, 2004.

Pursuant to the Arrangement, each shareholder of Rocky received for each share of Rocky held thereby, depending on the election of such holder, either C$6.10 in cash, 0.35078 of a trust unit of Enterra, or 0.35078 of an exchangeable share (each of which is exchangeable for a trust unit of Enterra subject to adjustment of the exchange ratio in accordance with the terms of the exchangeable shares).  

Upon completion of the Arrangement, an aggregate of 1,946,576 Enterra trust units, 341,882 exchangeable shares and cash in the amount of C$7,233,746 were issued or paid to the former shareholders of Rocky.
