NEWS RELEASE

MATERIAL SCIENCES CORPORATION REPORTS ON SALE OF EMD ASSETS

ELK GROVE VILLAGE, IL, June 21, 2005 – Material Sciences announced today that the company completed a transaction for the sale of substantially all of the assets of its EMD business segment. EMD focused primarily on the design, development and commercialization of field-effect technology for sensors, switches and interface solutions, under an exclusive license agreement for the consumer electronics and transportation markets with TouchSensor Technologies, LLC (TST).

The company believes that there are numerous market opportunities for field-effect technology, but concluded that the business is not a strategic fit with MSC’s primary coated and laminated material-based solutions. Accordingly, the company entered into and simultaneously completed a transaction on June 20, 2005, for the sale of a substantial portion of the assets (including fixed assets, intellectual property and other assets) of EMD to TST in consideration of the release from current and future contractual commitments to TST and the assumption of certain contractual obligations of EMD. EMD will be reported as a discontinued operation with effect from the second quarter of fiscal 2006.

As a result of the transaction, MSC was relieved of the fee obligations under the license agreement in fiscal 2006 of $2.8 million, as well as approximately $.8 million of obligations related to certain cost sharing arrangements between MSC and TST projected for the 18 months ending November 1, 2006. The company expects the transaction will result in a pretax loss of approximately $2.0 million, including severance and other transaction-related costs.
