1. BASIS OF PRESENTATION

The Company’s accounting policies are in accordance with accounting principles generally accepted in Canada. These policies are consistent with accounting principles generally accepted in the U.S., except as outlined in Note 12. The unaudited condensed consolidated financial statements have been prepared on a basis consistent with the accounting principles and policies reflected in the December 31, 2004 consolidated financial statements. These interim condensed consolidated financial statements do not include all disclosures normally provided in annual consolidated financial statements and should be read in conjunction with the most recent annual consolidated financial statements. The December 31, 2004 consolidated balance sheet was derived from the audited consolidated financial statements, but does not include all disclosures required by generally accepted accounting principles (“GAAP”) in Canada and the U.S. In the opinion of management, all adjustments (which included normal recurring adjustments) necessary for the fair presentation for the interim periods have been made. The results of operations and cash flows are not necessarily indicative of the results for a full year.

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts and other disclosures in these consolidated financial statements. Actual results may differ from those estimates.

Certain items in the 2004 financial statements have been reclassified for comparison to the 2005 presentation.

2. OIL AND GAS PROPERTIES AND INVESTMENTS

Included in proved properties as at March 31, 2005 and December 31, 2004 is $0.6 million of costs associated with future asset retirement and abandonment of oil and gas properties in the U.S.

Costs as at March 31, 2005 and December 31, 2004 of $34.6 million and $31.0 million, respectively, related to unproved oil and gas properties were excluded from the depletion and ceiling test calculations.

For the three-month periods ended March 31, 2005 and 2004, general and administrative expenses related directly to oil and gas acquisition, exploration and development activities, and investments in GTL and EOR projects of $0.9 million and $0.7 million, respectively, were capitalized.

3. LONG TERM ASSETS

During 2004, the Company acquired a 15% equity interest in Ensyn Petroleum International Ltd. (“EPIL”) and exclusive rights to use the proprietary Ensyn RTP^TM Technology (“RTP^TM Technology”) in key international markets. The RTP^TM Technology, patented in the U.S., Canada and other countries, upgrades the quality of heavy oil by producing lighter, more valuable crude oil. In December 2004, the Company and Ensyn Group, Inc. (“Ensyn”), the parent company of EPIL, announced the signing of an Agreement and Plan of Merger (“Merger Agreement”) in which Ensyn will be merged with the Company (“Merger”) and Ensyn will become a wholly owned subsidiary of the Company. With this Merger, the Company will gain full ownership of EPIL and the exclusive right to employ the RTP^TM Technology for petroleum process applications worldwide (See Note 11).

The cost to acquire the 15% equity interest in Ensyn Petroleum International Ltd. of $3.0 million plus $3.2 million and $2.5 million of costs as at March 31, 2005 and December 31, 2004, respectively, incurred by the Company associated with the Merger are included in long-term assets.
