        WHEREAS,
Coors Distributing Company ("CDC"), a Guarantor, has merged (the "Merger") with

        WHEREAS,

shall have all of the rights, protections, and immunities which the Trustees possess under the Indenture.
The recitals contained herein shall be taken as the statements of the Company, and the Trustees assume no responsibility for their correctness. The Trustees make no representations as to the validity
