Item 2.05.        Costs Associated with Exit of Disposal Activities.

         On December 3, 2004, Interstate Bakeries Corporation (the "Company")
committed to a plan to close its Florence, South Carolina bread and roll
bakery effective February 6, 2005. The Company is in the process of
consolidating operations in order to obtain production efficiencies and more
effectively allocate its production capacity. The Company determined that the
Florence bakery's production capacity could be effectively transferred to its
Charlotte and Rocky Mount, North Carolina bakeries. The closing of the
facility will affect approximately 200 employees. The Company's preliminary
estimate of charges to be incurred in connection with closure is approximately
$5,700,000 to $7,100,000, including approximately $1,700,000 to $2,100,000 of
severance charges, approximately $1,300,000 to $1,600,000 of charges relating
to clean-up of the facility, approximately $2,200,000 to $2,700,000 of asset
impairment charges, and approximately $500,000 to $700,000 in other charges.
The Company further estimates that approximately $3,420,000 to $4,260,000 of
such charges will result in future cash expenditures.

         A copy of the press release related to the closure of the Florence,
South Carolina bakery is hereby incorporated by reference and attached hereto
as Exhibit 99.1.
