Principal Documents

The following documents have been filed as part of this Annual Report on Form 40-F:

A. Annual Information Form

For our Annual Information Form for the fiscal year ended December 31, 2007, see Exhibit 99.1 of this Annual Report on Form 40-F.

B. Audited Annual Financial Statements

For our Consolidated Financial Statements for the fiscal year ended December 31, 2007, including the report of independent registered chartered accountants with respect thereto, see Exhibit 99.2 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 22 of the Notes to the Consolidated Financial Statements.

C. Management’s Discussion and Analysis and Results of Operations

For Management’s Discussion and Analysis and Results of Operations for the fiscal year ended December 31, 2007, see Exhibit 99.3 of this Annual Report on Form 40-F.

Disclosure Regarding Controls and Procedures.

(a) Certifications. See Exhibits 99.4 and 99.5 to this Annual Report on Form 40-F.

(b) Disclosure Controls and Procedures. As of the end of the registrant’s fiscal year ended December 31, 2007, an evaluation of the effectiveness of the registrant’s “disclosure controls and procedures” (as such term is defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) was carried out by the registrant’s management with the participation of the principal executive officer and principal financial officer. Based upon that evaluation, the registrant’s principal executive officer and principal financial officer have concluded that as of the end of that fiscal year, the registrant’s 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 in Securities and Exchange Commission rules and forms 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.

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.

(c) Management’s Annual Report on Internal Control Over Financial Reporting. The required disclosure is included in the “Management Report” that accompanies the registrant’s Consolidated Financial Statements for the fiscal year ended December 31, 2007, filed as part of this Annual Report on Form 40-F.

(d) Attestation Report of the Registered Public Accounting Firm. The required disclosure is included in the “Auditors’ Report” that accompanies the registrant’s Consolidated Financial Statements for the fiscal year ended December 31, 2007, filed as part of this Annual Report on Form 40-F.

(e) Changes in Internal Control Over Financial Reporting. During the fiscal year ended December 31, 2007, 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 registrant’s internal control over financial reporting.

Notices Pursuant to Regulation BTR
