ORBITAL ACQUIRES FOXBORO'S PROCESS GAS CHROMATOGRAPHY PRODUCT LINE

(Pomona, CA, 24 April 2000) - Orbital Sciences Corporation (NYSE: ORB) announced today that it has completed the purchase of The Foxboro Company's Process Gas Chromatography (PGC) product line. PGC analyzers are widely used by refining, petrochemical, natural gas, chemical and other industrial producers to measure chemical composition of process streams. Financial terms of the purchase were not disclosed.

Orbital will integrate the PGC product line into its Applied Instrument Technologies (AIT) business unit in Pomona, California. Orbital's AIT unit will assume responsibility for the ongoing service and support of the PGC products that are currently installed with customers, as well as the production and sales of new systems.
