Sea Launch Company,
LLC, and Inmarsat Ltd, the Total Communications Network(TM), announce the
signing of a launch services agreement under which Sea Launch will be the
contractor for the launch of the second Inmarsat I-4 satellite, presently
planned for 2005. The agreement, signed on December 16, 2003, includes an
option for an additional launch at a later date and for Sea Launch to be the
backup on the first Inmarsat I-4 launch, currently planned for late 2004.

“This is a significant milestone for Sea Launch and is further
confirmation of our enviable track record of reliability, credibility,
integrity and value,” said Jim Maser, president and general manager of Sea
Launch. “This contract represents an important step in broadening our
standing in the international launch and satellite community. We appreciate
Inmarsat’s confidence in the Sea Launch system and team, and we welcome this
highly-respected customer to our growing family of customers.”

The 5900 kg (13,000 lb) Inmarsat I-4 satellite is a Eurostar 3000 design
built by EADS Astrium and, when launched, will be the largest commercial
satellite. The Inmarsat 4 series of spacecraft, Inmarsat’s fourth generation
of satellites, are designed to support the new Broadband Global Area Network
(BGAN), which is currently planned to be introduced during 2005 to deliver
Internet and intranet content and solutions, video on demand,
videoconferencing, fax, e-mail, phone and LAN access at speeds up to
432 kbit/s to easily-used terminals the size of laptops. BGAN will also
functionally emulate third-generation (3G) cellular systems. Each satellite
will be 60 times more powerful than one of the present generation.

Inmarsat Ltd, headquartered in London, is the world’s leading mobile
satellite communications company. It operates a constellation of
geostationary satellites providing reliable voice, high and low speed data
service that extend phone, fax and data communications across the world.

Michael Storey, president and CEO of Inmarsat, said, “BGAN is a key
strategic investment for the company’s plans to pursue a range of new
opportunities at the convergence of information technology, telecoms and
mobility while continuing to serve traditional maritime, aeronautical,
land-mobile and remote-area markets.”
