Ball Aerospace and TENZING™ Form Strategic Alliance

September 19, 2000

Ball Aerospace & Technologies Corp. and Tenzing Communications, Inc., a global communication provider offering connectivity solutions for the frequent business traveler, today announced Ball Aerospace will be a provider of airborne equipment for the introduction of high-speed e-mail and Internet services to passengers via the Inmarsat 64 kbps Global Area Network (GAN).

Tenzing will use Ball Aerospace's AIRLINK® HSD avionics to upgrade existing Satcom installations or to equip new aircraft to offer the Inmarsat 64 kbps services. The AIRLINK® HSD avionics are easily integrated with most existing Aero-H/H+ Satcom antennas, including the AIRLINK® High Gain Antenna System, an Aero-H Satcom product that Ball Aerospace has been delivering for more than 10 years. Initial AIRLINK® HSD installations could happen in early 2001.

Ball Aerospace also recently announced it will be the multimedia equipment supplier to AIRIA, a joint venture between the company formerly called Live Inflight Video Entertainment and Inmarsat Ventures Ltd., that will be the first to deliver live, global news and sports broadcasts to aircraft. With the addition of the Ball Aerospace AIRLINK® Multimedia Unit, the AIRLINK® HSD infrastructure will be able to receive AIRIA's live television services.

Additionally, the equipment from Ball Aerospace will be upgradeable to offer 432 kbps to the aircraft when the Inmarsat 4 satellites are launched in 2004, utilizing the antennas currently installed on approximately 1400 aircraft worldwide.

Walter Crawford, Managing Director, Global Communications and Video Solutions, says, "Ball Aerospace has watched the Tenzing service offering advance in capability and airline acceptance over the last several months and is pleased to be associated with their broadband services. Utilizing existing Inmarsat satellites and airborne antennas, we will be able to support Tenzing's worldwide airline and passenger data communications."

John Wade, EVP Strategic Alliances of Tenzing, says, "Ball Aerospace has been a leader in airborne satellite communications for nearly 15 years. Tenzing is delighted to have the opportunity to work with Ball Aerospace, pioneering the next generation in airborne Internet services."
