Ultimate Security Systems Corporation and ImmunoTechnology Corp. Announce Extension of Deadline to Merge

IRVINE, Calif., March 31 -- Ultimate Security Systems Corporation (USSC) of Irvine, Calif., manufacturer of the Power Lock(TM) auto security system, and ImmunoTechnology (BULLETIN BOARD: IMNT) have announced that both parties have agreed to extend the original March 31, 2003 deadline to merge until April 16, 2003.

Under the terms of the Letter of Intent, IMNT will acquire 100% of the outstanding shares of common stock of Ultimate Security Systems Corporation in exchange for the issuance of shares of IMNT's common stock. "I'm optimistic about the completion of this merger," said James Cooper, CEO of Ultimate Security Systems Corporation. "Having some extra time is giving us an opportunity to gear up for the expansion and growth we anticipate as a result of the agreement."

Ultimate Security Systems Corporation developed and patented Power Lock(TM), the only solid-state auto security system that is guaranteed to prevent any vehicle from being hot-wired and driven away. The product attaches permanently to a vehicle's starter motor and cannot be circumvented by cutting and jumping ignition wires, the "hot-wiring" technique used by professional car thieves in the vast majority of stolen vehicle cases nationwide.
