Market Wire, February, 2008

AtHoc, Inc., the pioneer and leader in network-centric emergency notification systems, today announced the company was awarded a contract in support of the National Aeronautics and Space Administration's (NASA) Johnson Space Center. The contract was awarded to GMRI, a PC Mall Gov division, through their NASA SEWP (Solution for Enterprise-wide Procurement) contract, and it includes AtHoc IWSAlerts software licenses for primary and failover systems, as well as telephony communication services.

Once deployed, the AtHoc solution will cover all 13,000 employees at the Johnson Space Center's two main campuses located in Houston, Texas and Las Cruces, New Mexico. The primary system will be deployed on-site at the Houston facility, with the duplicate failover system housed at the White Sands Test Facility.

The Johnson Space Center complex in Houston is comprised of more than 100 buildings across 1,620 acres. It is the location of the Mission Control Center, which directs all space shuttle missions and activities aboard the International Space Station.

"We are excited and proud to win the contract award to support the Johnson Space Center," said Guy Miasnik, president and CEO of AtHoc. "This contract provides further momentum for AtHoc's expansion of emergency notification solutions within the federal civilian sector. It also strengthens our position as the leading provider of net-centric emergency notification systems for the federal government, with approximately one million government employees now protected and hundreds of facilities using our solutions."

The Johnson Space Center in Houston is home to NASA's human spaceflight programs and is responsible for training astronauts from both the U.S. and its international partners. The White Sands Test Facility in New Mexico serves as a backup shuttle landing site and as the coordinating facility for Project Constellation, which will replace the Space Shuttle program after 2010.
