Luminex Completes Purchase of Mainframe Business from Crossroads Systems

Riverside, CA, March 4, 2003 - Luminex Software, Inc. today announced that it has completed the purchase of the mainframe products business of Crossroads Systems, Inc (NASDAQ: CRDS). The purchase was completed pursuant to an agreement made in March 2002, under which Luminex initially operated as the exclusive reseller of Crossroads-Oregon mainframe products. Under the terms of that agreement, Luminex has now successfully met all of the required conditions and, as a result, has acquired ownership of the assets and intellectual property related to the mainframe products, including the exclusive right to manufacture and distribute those products.

Luminex intends to extend its market leadership in mainframe input/output (I/O) and control unit emulation by continuing to leverage the acquired technology in new directions.

"We are pleased to have reached this milestone," said Michael Saunders, President of Luminex. "The products and technology developed by the mainframe products group in Oregon, combined with its high caliber people, have made a major contribution to our mainframe solutions roadmap and now with our ownership of this technology, will become an even more important contributor to our future success."

"Luminex has been successful in selling and supporting our mainframe products under the reseller agreement and this purchase agreement enables Crossroads to focus on its strategy of data protection and storage connectivity for network attached storage", said Brian R. Smith, CEO of Crossroads Systems.

"Luminex's record of sustained profitability and strategic acquisitions has enabled a successful growth strategy during a challenging economic environment," said Arthur Tolsma, CEO of Luminex. "The synergies of the Oregon mainframe products team and our history of innovation will propel Luminex into a leadership position in the convergence of mainframe and open systems."
