AUDITED ANNUAL FINANCIAL STATEMENTS For Western Oil Sands' consolidated audited financial statements for the year ended December 31, 2005 and 2004, including the auditor's report with respect thereto, see Exhibit 2 of this Annual Report on Form 40-F. For a reconciliation of important differences between Canadian and United States generally accepted accounting principles, see Note 21 of the Notes to the Consolidated Financial Statements. C. MANAGEMENT'S DISCUSSION AND ANALYSIS For Western Oil Sands' Management's Discussion and Analysis for the year ended December 31, 2005, see Exhibit 3 of this Annual Report on Form 40-F. CONTROLS AND PROCEDURES Western Oil Sands maintains disclosure controls and procedures and internal control over financial reporting designed to ensure that information required to be disclosed in the reports filed under the Exchange Act, as amended, is recorded, processed, summarized and reported within the time periods specified in the Commission's rules and forms. Western Oil Sands' principal executive and financial officers evaluated the effectiveness of Western Oil Sands' disclosure controls and procedures as of the end of the period covered by this report and concluded that such disclosure controls and procedures are effective to ensure that information required to be disclosed by the Registrant in reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified and (ii) accumulated and communicated to the Registrant's management, including its principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure. However, as recommended by the Commission in its adopting release, the Registrant will continue to periodically evaluate its disclosure controls and procedures to ensure that information is recorded, processed, summarized and reported within the time periods specified in the Commission's rules and forms. It should be noted that while the Registrant's principal executive officer and principal financial officer believe that the Registrant's disclosure controls and procedures provide a reasonable level of assurance that they are effective, they do not expect that the Registrant's disclosure controls and procedures or internal control over financial reporting will prevent all errors and fraud. A control system, no matter how well conceived or operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. During the fiscal year ended December 31, 2005, there were no changes in Western Oil Sands' internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect, Western Oil Sands' internal control over financial reporting. AUDIT COMMITTEE FINANCIAL EXPERT The Registrant's Board of Directors has determined that Messrs. Robert Puchniak, Randall Oliphant and Mac Van Wielingen are audit committee financial experts (as defined in paragraph 8(b) of General Instruction B to Form 40-F) serving on its audit committee. Pursuant to paragraph 8(a)(2) of General Instruction B to Form 40-F, the Board has applied the definition of independence applicable to the audit committee members of the New York Stock Exchange ("NYSE") listed companies.
