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 13. The unaudited consolidated financial statements have been prepared on a basis consistent with the accounting principles and policies reflected in the December 31, 2003 consolidated financial statements, except for a change in the policy of accounting for stock based compensation which has been implemented retroactively with a restatement of prior period financial statements, and should be read in conjunction therewith. These interim 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, 2003 consolidated balance sheet, as restated, 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.

2. CHANGE IN ACCOUNTING POLICY

Prior to January 1, 2004, the Company accounted for options granted to employees and directors using the intrinsic-value of the options. Under this method, compensation costs were not recognized in the financial statements for share options granted at market value but rather disclosure was required, on a pro forma basis, of the impact on net income of using the fair value at the option grant date. The Company does, however, recognize compensation costs in its financial statements for options granted to non-employees after January 1, 2002 based on the fair value of the options at the date granted. The Company uses the Black-Scholes option pricing model for determining the fair value of options issued at grant date.

For fiscal years beginning on or after January 1, 2004, Canadian GAAP requires compensation costs to be recognized in the financial statements using the fair value based method of accounting for all stock options granted after January 1, 2002. Implementation of this change in accounting policy requires retroactive application with the option of restating financial statements of prior periods.

Accordingly, effective January 1, 2004, the Company changed its accounting policy, for Canadian GAAP purposes, to recognize compensation costs using the fair value based method of accounting for stock options granted to employees and directors after January 1, 2002. This change has been adopted retroactively and the Company has elected to restate the financial statements of prior periods (See Note 7).

3. OIL AND GAS PROPERTIES, EQUIPMENT AND INVESTMENTS

Capital assets categorized by geographical location are as follows:

In January 2004, the Company signed farm-out and joint operating agreements with Richfirst Holdings Limited (“Richfirst”), a wholly owned subsidiary of China International Trust & Investment Company to jointly develop the Dagang oil project. Richfirst acquired a 40% working interest in the project for $20.0 million following Chinese regulatory approvals, which were finalized in June 2004 (See Note 9). The carrying value of the Company’s oil and gas assets was reduced by $13.5 million for the amount of the proceeds associated with the sale of the working interest. The reduction in the carrying value does not significantly alter the depletion rate of the China oil and gas assets. The $6.5 million balance of the proceeds will fund a portion of Richfirst’s share of future Dagang oil project costs and the unspent balance was $0.8 million as at September 30, 2004.

As a result of the Company’s on-going evaluation of its GTL investments, $0.3 million of its investments were written down for the three-month period ended June 30, 2004 as the opportunity to build a 45,000-barrels per day GTL fuels plant in Oman failed to materialize due to a lack of sufficient uncommitted gas volumes to support a plant of that size.

4. LONG TERM ASSETS

In January 2004, the Company signed a Stock Purchase and Shareholders’ Agreement with Ensyn Group Inc. (“Ensyn Group”) and its subsidiary, Ensyn Petroleum International Ltd. (“Ensyn”), pursuant to which the Company acquired a 10% equity interest in Ensyn and exclusive rights to deploy the proprietary Ensyn RTPTM Process in several key international markets. The Company paid $2.0 million and will grant Ensyn rights to acquire equity interests in the Company’s international oil development projects that use the Ensyn RTPTM Process.

In August 2004, the Company acquired an additional 5% equity interest in Ensyn for $1.0 million. As at September 30, 2004, the 15% investment in Ensyn and related costs of $0.7 million are included in long-term assets (See Note 12).
