Enterra Energy Trust Announces Mailing of Meeting Materials to Unitholders in Connection with the Annual and Special Meeting to be held May 12, 2010

CALGARY, AB, April 21, 2010 /PRNewswire-FirstCall/ - Enterra Energy Trust ("Enterra", or the "Trust") is pleased to announce that it has mailed to its unitholders an information circular and proxy statement (the "Information Circular") and related materials in connection with the Annual and Special Meeting (the "Meeting") to be held in the Strand/Tivoli Room at the Metropolitan Centre, 333 - 4th Avenue S.W., Calgary, Alberta at 10:00 a.m. (Mountain Standard Time) on Wednesday, May 12, 2010. Unitholders will vote on, amongst other things, the proposed arrangement (the "Arrangement") involving the Trust, Enterra Energy Commercial Trust, Enterra Energy Corp., Enterra Production Partnership, Enterra Energy Partner Corp., Enterra Exchangeco Ltd., Equal Energy Ltd. ("Equal Energy"), 1528833 Alberta Ltd. and the Trust's unitholders at the Meeting.

If approved, the Arrangement will result in the reorganization of the Trust into a growth-oriented corporation that will be named "Equal Energy Ltd.". The Board of Directors and senior management of Equal Energy will be comprised of the current members of the Board of Directors and senior management of Enterra Energy Corp., the current administrator of the Trust. Additional information regarding the Arrangement and various other matters to be dealt with at the Meeting can be found in the Information Circular which is available on the Enterra website at www.enterraenergy.com.

Equal Energy will pursue the continued development of the Oklahoma based Hunton liquids-rich natural gas resource play. The company will work to further develop opportunities in the Circus, Oklahoma oil play, as well as the Cardium oil play in west central Alberta and various other Western Canadian Sedimentary Basin oil and gas prospects. In addition, the Arrangement will address the upcoming changes in the Canadian tax law associated with the establishment of the new federal tax structure on income trusts starting in January 2011.

Rationale for the Arrangement

Management of Enterra Energy Corp. and the Board of Directors have determined that enhanced unitholder and asset value could be realized and delivered more effectively through the reorganized structure rather than through the existing trust structure. In addition, in recommending the Arrangement to the Trust's unitholders, management and the Board of Directors believe that the Arrangement provides a number of strategic benefits to the Trust and its unitholders including, without limitation, the following:

    -   the Arrangement will provide for a simplified and more efficient
        corporate structure;
    -   the Arrangement will provide greater flexibility for growth and
        retention of capital;
    -   the Arrangement will enhance Equal Energy's access to capital;
    -   the Arrangement will eliminate the uncertainty and risks facing the
        Trust as a result of the changes to the tax legislation relating to
        income trusts; and
    -   the Arrangement will allow for rebranding under the name "Equal
        Energy" and allow the go-forward entity to have broader recognition
        in the capital markets.

Approvals and Timing

The completion of the Arrangement will be subject to receipt of all required regulatory, stock exchange and Court of Queen's Bench of Alberta approvals including approval of at least 66 2/3 percent of the votes by unitholders present in person or by proxy in a duly convened special meeting of the Trust's unitholders. All regulatory approvals for Enterra's conversion to a corporation are expected to be in place by late May 2010.
