1 FOR IMMEDIATE RELEASE EDITOR'S CONTACT: Tom Anderson QLogic Corporation Phone: 714/668-5092 Fax: 714/668-5090 E-mail: t_anderson@qlc.com LIEBL RETIRES AS CHAIRMAN OF QLOGIC CORPORATION COSTA MESA, Calif., May 21, 1999 - QLogic Corp. (NASDAQ:QLGC) announces the retirement of its first Chairman of the Board, Gary E. Liebl. Mr. Liebl has served as the company's Chairman since February of 1993, when it was spun out of Emulex Corporation as a separate public company. During those six years, the company has become a leader in pioneering the introduction of Fibre Channel technology and the market capitalization of QLogic has grown from about $35 million to approximately $2.0 billion. "I am extremely proud of the QLogic team and the company's tremendous accomplishments over the past six years," stated Mr. Liebl. "QLogic is a unique and remarkable success story. While I had not intended to participate for more than one year after the `spin,' I remained during the critical growth years. The company now has undeniable success momentum and a management team qualified to take it to the next level. This is an excellent time for me to step aside. I look forward to finally having the additional time I desire for not-for-profit endeavors and more time in Maui for my wife and myself." "As a board member of Emulex Corporation, Mr. Liebl was asked in 1992 to lead the planning and implementation of the creation of QLogic," according to George Wells, a company director. "In the process, he recruited the board of directors, all but one of whom are still involved. He also recruited the CEO, H.K. Desai, and has actively and very effectively supported management in key, strategic respects throughout the past five years. His skills including those involving corporate governance, will be missed." "Gary and I have collaborated very closely since I was selected President in 1995," stated H.K. Desai. "As a new CEO of a public company, our close interaction and his participation allowed QLogic to make critical strategic decisions quickly and effectively. I respect Gary immensely and will miss his participation at QLogic." The Board of QLogic has elected H.K. Desai as the new Chairman of the Board.
