Boeing Launch Services, Inc.
(BLS), a wholly-owned subsidiary of The Boeing Company, today
announced a contract with XM Satellite Radio for the launch of
the XM-4 satellite on a Sea Launch rocket in 2006.

The new contract is a direct arrangement between XM Satellite Radio and
Sea Launch Company, LLC. Sea Launch successfully placed the first two XM
satellites, “Rock” and “Roll” in orbit in 2001. The company also was selected
for the launch of the XM-3 satellite in 2004 as part of a delivery-in-orbit
contract with Boeing Satellite Systems, the manufacturer of all four

“We are excited about this opportunity to continue our relationship with
XM Satellite Radio,” said Jim Maser, president and general manager of Sea
Launch. “We helped put XM on the airwaves and now, we will support the
continued growth and success of their award-winning service to radio listeners
across the United States. These new contracts demonstrate our customer’s
confidence in our every-growing record of reliability and accuracy.”

The new contract, signed on August 5, directs the Sea Launch team to
deliver the powerful Boeing 702 spacecraft to geosynchronous transfer orbit
for a final orbital position at 115 degrees West Longitude in support of XM’s
on-going service requirements. The XM-3 spacecraft will be positioned at 85
degrees west longitude.

Designed for a 15-year lifespan, the Boeing 702 model spacecraft will each
generate 18 kilowatts of total power at the start of life in orbit. Alcatel
Space, of Toulouse, France, is providing the high-power, S-band, Digital Audio
Service (DARS) payloads for all of the XM spacecraft. For more information
