Explanatory Note

        The purpose of this amendment on Form 10-Q/A to the Quarterly Report on Form 10-Q of Molson Coors Brewing Company for the quarterly period ended March 27, 2005 is to clarify in Item 4. Controls and Procedures, due to the previously disclosed material weakness with respect to accounting for income taxes, our Global Chief Executive Officer and Global Chief Financial Officer concluded that our disclosure controls and procedures as a whole were not effective as of March 27, 2005. Because of the material weakness, we performed additional procedures to ensure that our disclosures included in the financial statements as of and for the quarter ended March 27, 2005, were fairly presented in all material respects in accordance with generally accepted accounting principles.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures

        Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission, and that such information is accumulated and communicated to the Company's management, including our Global Chief Executive Officer and Global Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In conjunction with the filing of this amended Form 10-Q, as a result of the restatement described in Note 1 to the Condensed Consolidated Financial Statements, our Global Chief Executive Officer and our Global Chief Financial Officer, with assistance from other members of management, have reviewed the effectiveness of our disclosure controls and procedures as of March 27, 2005, and, based on this re-evaluation, have determined that a material weakness in internal control over financial reporting existed at the end of the first quarter 2005 with respect to accounting for income taxes. Due to the material weakness our Global Chief Executive Officer and Global Chief Financial Officer concluded that our disclosure controls and procedures as a whole were not effective as of March 27, 2005. Because of the material weakness, we performed additional procedures to ensure that our disclosures included in the financial statements as of and for the quarter ended March 27, 2005, were fairly presented in all material respects in accordance with generally accepted accounting principles.

Accounting for Income Taxes

        In the course of its review of income taxes during the second quarter of 2005, management determined that the Company understated its income tax benefit in the first quarter of 2005 by a net $12.4 million (see Note 1). As a result of the circumstances involved, we have concluded that there was a material weakness in internal control over financial reporting at the end of the first quarter.

        In reaching this conclusion, management noted that during the first quarter, tax staff was directed toward developing and implementing the tax structure for the merger with Molson. This resulted in insufficient review of tax provision calculations. Together with inadequate systems to determine the provision for income taxes, the income tax benefit for the quarter was materially understated. In addition to amending our Form 10-Q for the first quarter of 2005 to correct the initial recording of a U.S. deferred tax asset as part of the purchase accounting for our U.K. acquisition, we have corrected these errors.

        We are taking the following steps to remediate this material weakness:

•

We have hired additional experienced tax staff including a new vice president of tax and two additional senior level tax managers;



•

We are implementing additional procedures to ensure adequate levels of review in this area; and



•

We will be implementing new software that will automate and improve controls in this activity.

        We intend to continue to monitor and upgrade our internal controls as necessary and appropriate for our business.

Changes in internal control over financial reporting

        The merger of Molson and Coors occurred after the fiscal year 2004 and therefore our Molson Canada and Kaiser Brazil business units will complete requirements under Internal Control over Financial Reporting Section 404 of the Sarbanes-Oxley Act of 2002 as of fiscal year end 2006. This effort is in progress and we are not aware of any material weaknesses in internal control over financial reporting. There were no other changes in internal controls in the first quarter that have materially affected, or are reasonably likely to materially affect the Company's internal control over financial reporting.

        The certifications attached as Exhibits 31 and 32 hereto should be read in conjunction with the disclosures set forth herein.
