In
January, 2008 we were served in a lawsuit entitled Olga Mata, Individually as Representative of the Estate of Elpido Mata
et al. vs. Energy Absorption Systems, Inc., Quixote Transportation Safety,
Inc., William Brothers Construction, Keller Crash Cushions d/b/a Contractors
Barricade Service, J.I.T. Distributing Inc. and Gustavo Reyes d/b/a Cerrito
Trucking, State of Texas, District Court of Brazoria County, No.
44361. This case involves a tractor-trailer collision with a crash cushion. The
plaintiffs allege various theories of liability against all defendants,
including negligence, misrepresentations and breach of warranty. We have
tendered the case to our insurance carrier and have answered the complaint. In
September the judge granted our motion for summary judgment and Quixote Transportation
Safety, Inc., Energy Absorption Systems, Inc. and Keller Crash Cushions (our
distributor) are now dismissed on all causes of action. Plaintiff may appeal.

 pre-existing environmental concerns at the property, and the lessor would be
 responsible for repairs needed at the facility to comply with any

|4. | The EAS Pell City facility generates a small amount
 of hazardous waste and stores the substances in an on-site collection area.
 Wastes, such as water-based-paint residues, MEK and toluene, are collected
 into labeled drums which are then collected by a third-party contractor for
 off-site disposal. Similarly, used motor oil and non-hazardous coolants are
 collected into labeled drums and taken off-site by third-party contractors
 for disposal.
