| (b) | Disclosure Controls and Procedures.  As of the end of the Registrant’s fiscal year ended December 31, 2011, 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) under the Exchange Act) was carried out by the management of the Registrant, with the participation of the President and Chief Executive Officer (“CEO”) and the Vice President, Finance and Chief Financial Officer (“CFO”) of the Registrant.  Based upon that evaluation, the CEO and CFO 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 (the “Commission”) rules and forms and (ii) accumulated and communicated to the management of the Registrant, including the CEO and CFO, to allow timely decisions regarding required disclosure. |

|   | effective in the preparation of financial statements for external purposes in accordance with IFRS.  Further, under Canadian securities legislation, the CEO and CFO are required to cause the Registrant to disclose any change in the Registrant’s ICOFR that occurred during the period beginning on October 1, 2011 and ending on December 31, 2011 that has materially affected, or is reasonably likely to materially affect, the Registrant’s ICOFR. The CEO and CFO have made the following disclosure:  No changes in ICOFR were identified during such period that have materially affected or are reasonably likely to materially affect the Registrant’s ICOFR.  There were no changes to ICOFR as a result of the transition to IFRS.  The CEO and CFO have made the same disclosures for the interim reporting periods ended March 31, 2011, June 30, 2011, and September 30, 2011. It should be noted that while the CEO and CFO 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. |
