Item 1.01 Entry into a Material Definitive Agreement.

On August 2, 2005, IMPCO Technologies, Inc. (“IMPCO”) and LaSalle Business Credit, LLC (“LaSalle”) entered into a Fourth Amendment to Loan and Security Agreement, and Limited Waiver, to amend the revolving Loan and Security Agreement dated July 18, 2003, as amended. A copy of the Fourth Amendment to Loan and Security Agreement, and Limited Waiver is attached as an exhibit to this current report on Form 8-K.

On July 18, 2003, IMPCO entered into a revolving Loan and Security Agreement, as subsequently amended, (the “Loan Agreement”) with LaSalle for a maximum amount of $12.0 million bearing an annual interest rate of prime plus 1%. At June 30, 2005, the annual interest rate was 7.25%. The borrowings under the Loan Agreement have been used for working capital purposes. On March 29, 2005, IMPCO and LaSalle mutually agreed to reduce the maximum borrowing amount under the Loan Agreement to $9.0 million and to extend it one additional year to July 18, 2007. IMPCO’s availability under this Loan Agreement is determined by a percentage of eligible accounts receivable and inventory balances as defined by the Loan Agreement. As of June 30, 2005, approximately $6.1 million was outstanding under this revolving loan and approximately $1.9 million was available and unused.

IMPCO was not in compliance with the Loan Agreement at March 31, 2005, since it did not meet the Consolidated Tangible Net Worth covenant and at June 30, 2005, since it did not meet the U.S. Minimum Pre-Tax Income covenant with respect to IMPCO’s fiscal second quarter ended June 30, 2005. On August 2, 2005, IMPCO and LaSalle agreed to amend the Loan Agreement to waive only the above events of non compliance and to amend and restate the relevant paragraphs of the Loan Agreement.
