FREMONT, Calif.--(BUSINESS WIRE)--May 11, 2001

Tiburon, Inc., an industry leader in public safety and criminal justice solutions, today announced an agreement to receive an investment from CompuDyne Corp. (Nasdaq:CDCY), an industry leader in sophisticated security products and solutions. The investment is the first step in a merger of the two companies.

Bruce Kelling, Tiburon's founder and CEO, says, "We are very excited to be able to partner with a company of the caliber of CompuDyne. The merger gives Tiburon the financial strength to meet its strategic goals. It provides capital market access, bonding, public stock for employee incentives, and stock and financing for acquisitions. In addition, Tiburon will serve as the centerpiece of CompuDyne's business, building on our public safety and justice business. We remain dedicated to our industry, customers, employees, shareholders, investors and business partners."

In addition to its security solutions, CompuDyne entered the inmate management software business in 1999 with the acquisition of the Corrections Information Systems division of BI, Inc. -- since renamed CorrLogic. Shortly after acquiring CorrLogic, CompuDyne made a strategic decision to expand into the Public Safety and Justice arena.

"Tiburon's solutions for public safety and integrated justice markets is a natural extension of our industry-leading position in the public security products, integration, and technology market," said Martin Roenigk, CEO of CompuDyne. "I am proud to say that Bruce Kelling and I share the same dedication to our clients and their ultimate satisfaction."
