Page 15 INTRODUCTION This Amendment No. 1 to Schedule 13D amends the Schedule 13D (the "Schedule") filed jointly on February 22, 2005,by: (a) Pentland Securities (1981) Inc. ("Pentland"); (b) 4280661 Canada Inc. ("4280661"); (c) Lincolnshire Holdings Limited ("Lincolnshire"); (d) 4198832 Canada Inc. ("4198832"); (e) Nooya Investments Limited ("Nooya"); (f) BAX Investments Limited ("BAX"); (g) 6339522 Canada Inc. ("6339522"); (h) DJS Holdings Ltd. ("DJS"); (i) 6339549 Canada Inc. ("6339549"); (j) Trust u/w/o Thomas Henry Pentland Molson ("Molson Trust"); (k) Eric Herbert Molson ("Eric Molson"); (l) Stephen Thomas Molson ("Stephen Molson"); and (m) Andrew T. Molson ("Andrew Molson") (the "Reporting Persons"). This Amendment No. 1 is being filed by the Reporting Persons to report that, effective January 1, 2006, Eric Molson and Stephen Molson have resigned as trustees of the Molson Trust, as officers and directors of BAX and DJS, and as officers of 6339522 and 6339549 and that, as a result of such actions, none of the Reporting Persons is subject to any further reporting obligations under Section 13(d) of the Securities Exchange Act of 1934 (the "Exchange Act") and Rule 13d-1 thereunder with respect to the Class B Common Stock (the "Class B Common Stock") of Molson Coors Brewing Company (the "Company"). This Amendment No. 1 also reports changes in certain Reporting Persons' percentage ownership of the outstanding shares of Class B Common Stock due to changes in the number of such shares outstanding. Unless otherwise indicated, all capitalized terms used herein shall have the meanings set forth in the Schedule and, unless amended hereby, all information previously filed remains in effect. Item 5. Interest in Securities of the Company. Items 5(a) and(b) of the Schedule are amended and supplemented by adding the following at the end thereof: On January 1, 2006, Eric Molson and Stephen Molson resigned as trustees of the Molson Trust, as officers and directors of BAX and DJS, and as officers of 6339522 and 6339549 and were replaced by other trustees, officers and directors. As trustees of the Molson Trust, Eric Molson and Stephen Molson may have been deemed to share beneficial ownership of the 862,267 shares of Class B Common Stock beneficially owned by the Molson Trust, which beneficial ownership both have disclaimed. In addition, the Molson Trust, BAX, 6339522, DJS and 6339549 may each have been deemed to be a member of a "group" under Rule 13d-5(b)(1) with Eric Molson and Stephen Molson and to thus share beneficial ownership of the 3,688,608 shares of Class B Common Stock beneficially owned by Eric Molson and Stephen Molson, as to which the Molson Trust, BAX, 6339522, DJS and 6339549 have disclaimed beneficial ownership. As a result of their resignations as trustees, Eric Molson and Stephen Molson may no longer be deemed to share beneficial ownership of the shares of Class B Common Stock beneficially owned by the Molson Trust, thereby reducing Eric Molson's aggregate beneficial ownership to 3,687,312 shares of Class B Common Stock (4,549,579 shares less the 862,267 shares owned by the Molson Trust) and Stephen Molson's aggregate beneficial ownership to 3,626,062 shares of Class B Common Stock (4,488,329 shares less the 862,267 shares owned by the Molson Trust), each of which constitutes 4.3% of the outstanding shares, based on the number of outstanding shares reported in the Quarterly Report on Form 10-Q filed by the Company on November 4, 2005 (the "Quarterly Report"). As a further result of these actions, the Molson Trust, BAX, 6339522, DJS and 6339549 may no longer be deemed to be members of a group. Consequently, none of the Reporting Persons has beneficial ownership of more than 5% of the outstanding shares of Class B Common Stock, and thus none of the Reporting Persons is subject to any further reporting obligations under Section 13(d) of the Exchange Act and Rule 13d-1 thereunder. Page 16 Solely, as a result of an increase in the number of outstanding shares of the Company's Class B Common Stock as reported in the Quarterly Report, the percentage ownership of certain of the Reporting Persons has been reduced from that reflected in the Schedule. These percentages are as follows: Pentland (4.2%); 4680661 (4.2%); Lincolnshire (4.3%); Nooya (4.2%); and Andrew Molson (4.2%). Item 5(e) of the Schedule is amended and supplemented by adding the following at the end thereof: On January 1, 2006, Eric Molson and Stephen Molson resigned as trustees of the Molson Trust, as officers and directors of BAX and DJS, and as officers of 6339522 and 6339549 and were replaced with other trustees, officers and directors. For the reasons set forth in Items 5(a) and (b), above, which are incorporated by reference into this Item 5(e), as of that date, none of the Reporting Persons was subject to any further reporting obligations under Section 13(d) of the Exchange Act and Rule 13d-1 thereunder. Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer. Item 6 of the Schedule is amended and supplemented by adding the following at the end thereof: On May, 12, 2005, Eric Molson and Andrew Molson each received 1,500 Class B restricted stock units under the Company's Incentive Compensation Plan. Under the Restricted Stock Unit Agreements entered into by Eric Molson and Andrew Molson in connection with these grants, the restricted stock units vest on the third anniversary of the date of grant, subject to acceleration or cancellation upon the occurrence of certain events.
