Mr. Peter J. Burlage, Chief Executive Officer of the Company, stated, “I am very pleased to report our third consecutive quarter of year-over-year increases in revenues and net earnings with both of our business segments, Environmental Systems and Separation/Filtration, contributing to our success with exceptional performances. The outlook for the energy and environmental markets that we served continues to be very favorable. Our backlog at March 31, 2008 was approximately $63 million and includes $1 million from two large projects that totaled $53 million. We largely completed those two projects in the third quarter and recorded $8 million in revenues. Our backlog at December 31, 2007 was approximately $69 million. Order flow in both of our business segments is historically volatile due to project size, and it is not unusual to see order intake change significantly from quarter-to-quarter. We continue to see robust bid activity as our markets remain strong.”

Mr. Burlage further commented, “After the close of the third quarter, we announced the acquisition of privately owned Nitram Energy, Inc., and I am pleased to report that the acquisition of Nitram closed on April 30th. Nitram is a profitable and growing business and we project that this transaction will be accretive to our shareholders. We are very excited about the combination of the Nitram organization with Peerless as their products enjoy excellent reputations in the market place. We also want to welcome all Nitram employees and we are looking forward to sharing our excitement about this combination with our customers.”
