Cubic’s Power Amplifier Business Receives Boost with
$15.1 Million Contract from Rockwell Collins

SAN DIEGO, Calif., July 5, 2005–The defense segment of Cubic Corporation (AMEX:CUB) has received a three-year, $15.1 million contract from Rockwell Collins to supply 1 kilowatt and 4 kilowatt HF power amplifiers that will be used to support domestic and international programs including the US Department of Homeland Security’s various communications programs.

The company will begin fulfilling orders under a master purchase agreement that covers the first 24 months of the contract, valued at $8.6 million. The first deliveries will begin in November of this year.

“Rockwell Collins and Cubic have complementary capabilities in the communications and defense electronics arena, and have forged a growing business relationship. This most recent contract award further strengthens that relationship,” said Rick Lober, senior vice president for Cubic’s Communications & Electronics business unit.

Power amplifiers are used to extend long range, High Frequency (HF) communications. During an emergency situation, where traditional communications can be disrupted, HF systems provide the most reliable backup. Today’s advances in automated HF linking and HF e-mail, have regenerated interest in maintaining and updating aging HF networks. Cubic, in partnership with Rockwell Collins, is proud to be the supplier of choice for the United States Government.

“We have seen an increase in power amplifier orders over the past few years,” said Dan McCormick, vice president of Communications, Intelligence and Avionics for Cubic’s Communications and Electronics business unit. “One of the lessons learned from 9/11 was the value of maintaining a strong, upgraded HF communications infrastructure to coordinate state, local and federal emergency management.”

The Cubic Defense Applications group, one of Cubic Corporation’s two major segments, is a world leader in realistic combat training systems, mission support services and defense electronics. The corporation's other major segment, Cubic Transportation Systems, designs and manufactures automatic fare collection systems for public mass transit authorities.
