First Quarter Review

During the first quarter of 2010, the Company closed on the second investment pursuant to the previously announced $15 million investment agreement with Alliance Success Holding Group Limited ("Alliance"). These funds helped satisfy outstanding bank debt and working capital commitments, outstanding LLR obligations with the Energy Resources Conservation Board ("ERCB") and several crown and private land and property acquisitions.

    
    -   At Breton, the Company spent $1 million on remediation and
        reclamation associated with the abandonment of several suspended oil
        flow-lines. Several suspended wells were reactivated and a geological
        study aimed at defining development opportunities within this 80
        million barrel pool was commenced. $1.8 million was spent on Alberta
        crown land sales to acquire a further two sections of land with
        Cardium oil potential. The Company also acquired three sections of
        land and 10 bopd of Cardium production in a $1.45 million private
        transaction. Anterra now owns a total of seven sections of Cardium
        land in the Breton area.

    -   At Abbott, in Saskatchewan the Company acquired 12 sections of land
        with Bakken potential in the Abbott area at a total cost of $0.45
        million, giving the Company a total of 17 sections of Bakken lands in
        the area. Anterra is seeking a partner to help explore and develop
        these lands.

    -   At Frontier in Saskatchewan the Company was active on its Lower
        Shaunavon project completing clean out activities on the Frontier LSD
        15-07 well and abandoning the horizontal well at LSD 04-01 in
        Claydon. At Frontier the horizontal leg of the well remains plugged
        at the third frac interval with production now averaging 10 bopd.
        Anterra has a 30% interest in the well. The Company is assessing
        further opportunities on the property although there will be minimal
        expenditures during the remainder of the year.

    -   On the Company's legacy properties a short leg horizontal well was
        drilled at Matziwin at no cost to Anterra with the Company retaining
        a 40% interest in the well. The well currently produces 20 bopd
        (gross).

    -   The midstream business at Breton continues to perform well mainly
        because of its location which is central to the Cardium activity
        taking place in the Pembina area.
    

Outlook

Operationally many of the maintenance projects that had been delayed during 2009 were completed in the first quarter of 2010 resulting in negative funds flow for the quarter. Many of these projects are now complete with production from the legacy assets back at 180 boepd and we now expect positive funds flow for the balance of the year.

The focus is now on having several horizontal wells drilled on the Cardium lands in the Breton area over the summer. The Company is in discussions with several parties on this project and expects to be in a position to drill up to three horizontal wells with multi stage fracs during the third quarter of the year. With midstream infrastructure in the area Anterra is well positioned to get production to market quickly and at minimal cost to the Company and its partners. The Company has flexibility in its capital plan to increase its capital expenditures above the 2010 budget of $8.5 million through joint ventures and partnerships on its Cardium, Bakken and Lower Shaunavon projects.

On the corporate front, the Company is actively evaluating property acquisitions within its core areas and seeks to close several small acquisitions during the year.
