Item 1.01 Entry into a Material Definitive Agreement.

On September 6, 2005, Lapco Industrial Parks, the lessor under the master lease, granted its consent, which was a condition to the effectiveness of the sublease, to a premises sublease agreement between Monterey Carpets, Inc., as sublessor (“Monterey”), and IMPCO Technologies, Inc., as sublessee (“IMPCO” or “We”), for a 108,000 square foot building, including 4,000 square feet of office space, located on 4.5 acres of land in Santa Ana, California (the “Santa Ana Facility”). The sublease term is 13 years beginning on September 1, 2005, and the rent will be $714,000 per year increasing by 3% per year, which is abated for the first three months of the sublease provided that IMPCO does not default on the sublease during that period.

Item 2.05 Costs Associated with Exit or Disposal Activities.

We expect to close our combined headquarters and production facility in Cerritos, California and relocate our headquarters and most of our production activities to the Santa Ana Facility by December 31, 2005. We also plan to relocate certain of our current production facilities in Cerritos to our BRC facility in Cherasco, Italy. We believe the new location has sufficient space to modernize and consolidate most of our North American production and component engineering facilities. As a global leader in the alternative fuels marketplace, we believe that the new location will position us better to capitalize on new products and markets as a result of improved efficiencies, capabilities and capacity. Our strategy is to install new state of the art production lines, machining and test equipment in the Santa Ana Facility.

We expect to recognize charges against income currently estimated at approximately $0.1 million and $0.7 million during the third and fourth quarters of 2005, respectively, in connection with the closure of Cerritos and the relocation of our operations to the Santa Ana Facility. Included in the estimated total charges of approximately $0.8 million, are approximately $0.3 million for impairment loss of leasehold improvements and furniture and fixtures, approximately $0.2 million for the recognition of incremental rent expense for the Santa Ana Facility prior to the planned exit of the Cerritos facility by December 31, 2005, relocation and set-up costs in the new facility of approximately $0.2 million and the fair value of the remaining Cerritos lease obligation of approximately $0.1 million. Approximately $1.3 million represents estimated total cash outflows during the third and fourth quarters of 2005, which includes leasehold improvements of approximately $0.9 million in the Santa Ana Facility and prepaid expenses of $0.1 million.
