FOR IMMEDIATE RELEASE

STRATEX NETWORKS RESPONDS TO
WESTERN MULTIPLEX DECISION NOT TO ACCEPT PROPOSAL

SAN JOSE, CA., March 6, 2002—DMC Stratex Networks, Inc. (NASDAQ: STXN), one of the world's foremost solutions providers for mobile applications and broadband wireless access, confirmed today that the Board of Directors of wireless equipment maker Western Multiplex Corporation (NASDAQ: WMUX) had announced a decision not to pursue the strategic combination proposed by Stratex Networks whereby shareholders of Western Multiplex would receive 0.5215 shares of Stratex Networks in exchange for each outstanding share of Western Multiplex. The offer was made at a significant premium to Western Multiplex's current transaction with Proxim, Inc.

Commenting on this development, Charles D. Kissner, Chairman and CEO of Stratex Networks said, "Ours is a highly compelling offer delivering substantial short and long term value to the stockholders of Western Multiplex. It would bring together companies with complementary products, markets, customers and channels. We are surprised that the Board of Directors of Western Multiplex has not recognized the merits of our offer."

"We will carefully study our options regarding the proposed combination and urge the Board of Directors of Western Multiplex to reconsider its initial reaction," continues Kissner. "Stratex Networks continues to make excellent progress on its principal business strategies. We will also continue to evaluate other potential business opportunities that add to and leverage our core business."
