Item 2.05      Costs Associated with Exit or Disposal Activities.

         On May 4, 2005, Interstate Bakeries Corporation (the "Company") issued
a press release, attached hereto as Exhibit 99.1 and hereby incorporated by
reference, announcing that, as part of its previously announced efforts to
address its continued revenue declines and high-cost structure, it plans to
consolidate operations in its Mid-Atlantic Profit Center ("PC") by closing its
bakery in Charlotte, North Carolina and consolidating routes, depots and thrift
stores in North Carolina, South Carolina and Virginia. The Company issued
Worker Adjustment and Retraining Notification, or WARN, notices to workers in
the Mid-Atlantic PC on the same date. The Company expects to complete the
consolidation of the Mid-Atlantic PC by July 23, 2005, subject to bankruptcy
court approval. The consolidation is expected to affect approximately 950
workers in the Mid-Atlantic PC.

         The Company's preliminary estimate of charges to be incurred in
connection with the Mid-Atlantic PC consolidation is approximately $15 million,
including approximately $3 million of severance charges, approximately $8.5
million of asset impairment charges, and approximately $3.5 million in other
charges. IBC further estimates that approximately $6 million of such costs will
result in future cash expenditures. In addition, the Company intends to spend
approximately $2 million for capital expenditures and accrued expenses to
effect the consolidation.

Item 2.06      Material Impairments.

         The information reported in Item 2.05 "Costs Associated with Exit or
Disposal Activities" is hereby incorporated by reference. The Company's
preliminary estimate of non-cash asset impairment charges to be incurred in
connection with the Mid-Atlantic PC consolidation is approximately $8.5
million. The charge relates primarily to write-downs of machinery, equipment
and real property to their estimated fair values.
