AUDITED ANNUAL FINANCIAL STATEMENTS For Western Oil Sands' consolidated audited financial statements for the year ended December 31, 2006 and 2005, including the auditor's report with respect thereto, see Exhibit 2 of this Annual Report on Form 40-F. The audit by PricewaterhouseCoopers LLP ("PWC") of management's evaluation of the effectiveness of internal control over financial reporting is set forth in 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 audited financial statements for the year ended December 31, 2006. C. MANAGEMENT'S DISCUSSION AND ANALYSIS For Western Oil Sands' Management's Discussion and Analysis for the year ended December 31, 2006, see Exhibit 3 of this Annual Report on Form 40-F. CONTROLS AND PROCEDURES DISCLOSURE CONTROLS As of December 31, 2006, an evaluation was carried out, under the supervision of and with the participation of management, including the President and Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO"), of the effectiveness of our disclosure controls and procedures as defined in Canada in Multilateral Instrument 52-109, Certification of Disclosure in Issuers' Annual and Interim Filings, and in the United States by Rule 13a-15(e) under the SECURITIES AND EXCHANGE ACT OF 1934, as amended (the "Exchange Act"). Based on that evaluation, the CEO and CFO concluded that the design and operation of our disclosure controls and procedures were effective as at December 31, 2006 to ensure that information required to be disclosed by us in reports that we file under the Exchange Act, is gathered, reported, processed, summarized and reported within the time periods specified in the Securities and Exchange Commissions rules and forms and is accumulated and communicated to the management of Western Oil Sands, including the CEO and CFO, to allow timely decisions regarding required disclosure as specified under Canadian and U.S. securities laws. INTERNAL CONTROL OVER FINANCIAL REPORTING Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended and in Canada as defined in Multilateral Instrument 52-109 - Certification of Disclosure in Issuers' Annual and Interim Filings. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of our financial reporting and preparation of our financial statements for external purposes in accordance with accounting principles generally accepted in Canada. Our internal control over financial reporting includes those policies and procedures that: pertain to the maintenance of records that in reasonable detail accurately and fairly reflect our transactions and disposition of the assets; provide reasonable assurance that transactions are recorded as necessary to permit preparation of our financial statements in accordance with generally accepted accounting principles and that receipts and expenditures of our assets are being made only in accordance with authorizations of our management and directors; and provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our internal control over financial reporting as of December 31, 2006. In making this evaluation, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework. There was one exclusion from our evaluation. Our 20% undivided working interest in the Alberta Oil Sands Project (the "AOSP"), was excluded from our evaluation as we do not have the ability to dictate or modify this entity's internal control over financial reporting, and we do not have the ability, in practice, to assess those controls. However, we have assessed our internal control over financial reporting with respect to the inclusion of our share of the AOSP and its results of operations in our consolidated financial statements. For further discussion of this exclusion from the scope of our evaluation see "Scope of Management's Report on Internal Control over Financial Reporting" below. Based on our evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2006. Our management's evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2006, has been audited by PWC, as stated in their report in Exhibit 2 of this Annual Report on Form 40-F. SCOPE OF MANAGEMENT'S EVALUATION OF INTERNAL CONTROL OVER FINANCIAL REPORTING Western Oil Sands is the holder of a 20% undivided interest in the AOSP and conducts the operation of the AOSP through a joint venture agreement (the "Agreement") with Chevron Canada Limited, the other 20% interest holder, and Shell Canada Limited ("Shell"), the 60% interest holder. The Agreement is structured such that Shell, as the project administrator and controller of the executive committee of the AOSP, is delegated all managerial responsibilities, including the ability to control operations, create accounts and keep internal controls over the AOSP. Shell charges us our proportionate share of the expenditures and provides us with our proportionate share of saleable synthetic crude which we market directly to third parties. Pursuant to the Agreement, and as described below, we have the contractual right to audit Shell's determination of our share of costs and outputs of the AOSP. During our 2006 fiscal year, our 20% undivided working interest in the AOSP comprised 96% of our total Property, Plant and Equipment, 100% of Operating Expenses, 54% of Purchased Feedstock, and 64% of Research and Business Development Expense as at and for the year ended December 31, 2006. However, we do not have the right or ability to dictate or modify the internal control over financial reporting of the AOSP, and we do not have the ability, in practice, to evaluate those controls. Further, we are not able to influence the control environment or control evaluations of the AOSP. As a result, we have excluded the AOSP from our evaluation of internal control over financial reporting relating to the AOSP. Pursuant to the Agreement, we have a control structure which includes, among other things, the following: o the right to participate in the committee that grants the authority under which all other committees operate including the approval of the annual budget; o the right to participate in the committee that reviews operations and capital spending as well as the approval of certain spending and contracts; o the right to participate in quarterly accounting and audit committee meetings; and o the right to participate in other committees and work groups as needed. In addition, we have and we exercise our right to audit, on a routine basis, Shell's determination of our share of costs as noted and outputs of the AOSP. Although these activities do not provide the ability to evaluate the internal control over financial reporting of the AOSP, the foregoing constitute a control environment for the purposes of evaluating our internal control over financial reporting. Accordingly, despite the exclusion of the AOSP from our management's review, our management has evaluated our internal control over financial reporting with respect to the inclusion of our share of the AOSP and its results in our consolidated financial statements. CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING No changes were made in our internal control over financial reporting during the year ended December 31, 2006, that have materially affected, or are reasonably likely to affect, our internal control over financial reporting. AUDIT COMMITTEE FINANCIAL EXPERT Western Oil Sands' Board of Directors has determined that Messrs. Robert Puchniak, Randall Oliphant, Oyvind Hushovd and Fred Dyment (Mr. Dyment was appointed to the Audit Committee on January 1, 2007) are audit committee financial experts (as defined in paragraph 8(b) of General Instruction B to Form 40-F) serving on its audit committee.

CODE OF ETHICS The Board has adopted a written Code of Ethics and Business Conduct (the "Code") for directors, officers and employees of Western Oil Sands and its subsidiaries. A copy of the Code was filed on November 24, 2006 and is accessible through SEDAR at www.sedar.com. A copy of the Code may also be obtained upon request by contacting Western Oil Sands at Suite 2400, Ernst & Young Tower, 440 Second Avenue S.W., Calgary, Alberta, T2P 5E9, telephone: (403) 233-1700. The Code provides that directors, officers and employees must, among other things: (a) avoid situations that may result in a conflict or perceived conflict between personal interests of directors, officers and employees and the interests of Western Oil Sands; (b) provide full disclosure of any actual or potential conflicts of interest in accordance with applicable legislation; (c) at all times comply fully with applicable law and avoid any situation which could be perceived as improper or unethical; (d) maintain the confidentiality of all non-public information relating to Western Oil Sands; (e) protect the property of Western Oil Sands and use such property only for authorized business purposes; and (f) not hold any significant financial interest, either directly or indirectly, in an organization which has a relationship with Western Oil Sands. Compliance with the Code is monitored by the Board. Where a director or officer has any interest in or a perceived conflict involving a contract or business relationship with Western Oil Sands, that director or officer is excluded from all discussions and deliberations regarding the contract or relationship and such director abstains from voting in respect thereof. Members of the Board and executive officers have disclosed to Western Oil Sands all directorships held by such member and the existence and nature of any interests that could result in a conflict situation with Western Oil Sands.

Since the adoption of the Code, there have not been any amendments to the Code or waivers, including implicit waivers, from any provisions in the Code. In addition, to the knowledge of the Board, there have been no departures from the Code during the year ended December 31, 2006 that would require the filing of a material change report under Canadian security laws.
