DISCLOSURE CONTROLS AND PROCEDURES

        The Registrant carried out an evaluation as of the end of the period covered by the report, under the supervision and with the participation of the Registrant's senior executive officers, including the Registrant's Chief Executive Officer and Treasurer, of the effectiveness of the Registrant's disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) of the Securities and Exchange Act of 1934 (the "Exchange Act"). Based on that evaluation, the Chief Executive Officer and Treasurer have concluded that the Registrant's disclosure controls and procedures as of October 31, 2006 were effective to ensure that information required to be disclosed by the Registrant in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission's rules and forms.


MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

        Senior executive officers of the Registrant are responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process to provide reasonable assurance regarding the reliability of the Registrant's financial reporting for external purposes in accordance with accounting principles generally accepted in Canada and in the United States of America. Internal control over financial reporting includes maintaining records that in reasonable detail accurately and fairly reflect our transactions and dispositions of the assets of the Registrant; providing reasonable assurance that transactions are recorded as necessary for preparation of our financial statements in accordance with generally accepted accounting principles; providing reasonable assurance that receipts and expenditures are made in accordance with authorizations of management and directors of the Registrant; and providing reasonable assurance that unauthorized acquisition, use or disposition of company assets that could have a material effect on the Registrant's financial statements would be prevented or detected on a timely basis. Because of its inherent limitations, internal control over financial reporting is not intended to provide absolute assurance that a misstatement of our financial statements would be prevented or detected.

        Further, the evaluation of the effectiveness of internal control over financial reporting was made as of a specific date, and continued effectiveness in future periods is subject to the risks that controls may become inadequate because of changes in conditions or that the degree of compliance with policies and procedures may decline.

        Senior executive officers conducted an evaluation of the effectiveness of the Registrant's internal control over financial reporting based on the framework and criteria established in Internal Control — Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission. This evaluation included review of the documentation of controls, evaluation of the design effectiveness of controls, testing of the operating effectiveness of controls and a conclusion on this evaluation. Based on this evaluation, senior executive officers concluded that the Registrant's internal control over financial reporting was effective as of October 31, 2006.

        During the fiscal year ended October 31, 2006, there were no changes in the Registrant's internal control over financial reporting that have materially affected or are reasonably likely to materially affect the Company's internal control over financial reporting (as defined in Rules 13(a)-15(f) and 15d-14(f) under the Securities Exchange Act of 1934).

        Senior executive officers' assessment of the effectiveness of the Registrant's internal control over financial reporting as of October 31, 2006 has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report.


AUDIT COMMITTEE FINANCIAL EXPERT

        Douglas E. Heagle serves as a member of the audit committee of the Registrant's Board of Directors. The Board of Directors has reviewed the definition of "audit committee financial expert" under item 8(a) of General Instruction B to Form 40-F and determined that Douglas E. Heagle satisfies the criteria for an audit committee financial expert under the Exchange Act. The SEC has indicated that the designation of Douglas E. Heagle as an audit committee financial expert does not make Douglas E. Heagle an "expert" for any purpose, impose any duties, obligations or liability on Douglas E. Heagle that are greater than those imposed on members of the audit committee and board of directors who do not carry this designation or affect the duties, obligations or liability of any other member of the audit committee. All members of the audit committee are independent as defined in Section 10A(m)(3) of the Securities Exchange Act of 1934, as amended and Rule 10A-3(b)(1) promulgated thereunder.



CODE OF ETHICS

        The Registrant has adopted a code of ethics that applies to the Registrant's principal executive officer, principal financial officer and principal accounting officer. A copy of Registrant's code of ethics is available to any person without charge, upon written request made to Catherine A. Spackman, Treasurer at Hallmark Estates, #805, 1323-15th Avenue S.W., Calgary, Alberta, Canada (403) 228-5861.
