      Purchase Agreement), (3) the contingent Earn-Out Payment (as defined in

Section 9.03 of the Credit Agreement, the Borrower may acquire MBA Shares from
Bestfoods as payment for amounts required to be paid to the Borrower pursuant to
Article X of the Mueller's Brand Asset Purchase Agreement, so long as (i) such
acquisition is made in accordance with the requirements of Section 10.8 thereof,

the Borrower's forgiveness of Bestfood's obligation to make a cash payment
pursuant to said Article X (with such foregiveness to be in a like amount as the
