National Technical Systems Announces Status of the Santa Clarita Property Sale

National Technical Systems, Inc. (Nasdaq: NTSC) (NTS) announced today that it has been unable to sell its 118 acre parcel in Santa Clarita, California on terms acceptable to the Company. The parcel has been listed for sale since August 2007.

Dr. Jack Lin, Chairman of NTS said "Despite vigorous efforts to sell the parcel to a developer, the continuing deterioration of the commercial real estate market has significantly impacted interest in undeveloped Santa Clarita property. The recent bankruptcy of a large developer/landowner in the general vicinity also is expected to adversely affect land values in the area. We will continue to pursue all avenues available to us, including a possible arrangement with a developer, but there can be no assurance that a sale or other arrangement on acceptable terms can be achieved."
