                   in Growing Markets for Video Data Links

CARLSBAD, Calif., June 21 /PRNewswire-FirstCall/ -- ViaSat Inc. (Nasdaq: VSAT), a satellite and wireless communication technology provider to government and commercial markets, has acquired Enerdyne Technologies Inc., a privately-held provider of innovative video data link equipment and digital video systems for defense and intelligence markets, primarily for unmanned aerial vehicle (UAV) applications. The acquisition will combine ViaSat expertise and technology with Enerdyne's successful video data link business to expand ViaSat's offerings into growing Department of Defense (DoD) markets for persistent video surveillance and video data links.

Terms of the acquisition include initial consideration of approximately $17.0 million (approximately $16.4 million in ViaSat common stock and $600,000 in cash) with additional consideration of approximately $8.7 million to be paid in common stock and/or cash based on Enerdyne meeting certain financial performance targets within the next four years. In the first year, the acquisition is expected to be non-dilutive to non-GAAP earnings, which excludes the effects of acquisition charges related to the amortization of intangible assets and the expense impact associated with FAS123R, for ViaSat. However, ViaSat has not completed its valuation analysis and, accordingly, has not determined the impact to GAAP earnings.

"Enerdyne has strong leadership and an excellent technical staff that has built a successful business by innovating new products and services to help solve complex defense intelligence issues. We are really excited about adding the capabilities of that team to ViaSat," said Mark Dankberg, ViaSat chairman and CEO. "The acquisition represents a unique opportunity to complement their products with our technology and deliver additional video products to our defense clients."

"We've worked hard to develop the kind of video data links that our armed forces need, and with ViaSat as our corporate parent, we feel confident that we now have the market presence and backing required to satisfy the demand for this equipment," said Brandon Nixon, Enerdyne CEO. "We're thrilled to become part of a company with ViaSat's capability and reputation."

Since its inception in 1984, Enerdyne (www.enerdyne.com) has provided military-qualified video compression systems for intelligence, surveillance, and reconnaissance (ISR) applications. In recent years, Enerdyne has expanded its product offering to provide highly integrated video data link equipment for the Special Operations Forces and Intelligence (SOF/I) market, the UAV industry, and other DoD applications. The EnerlinksII™ video data link simultaneously transmits video, data, and audio from multiple sensor sources with high bandwidth efficiency and outstanding link performance. Its size, weight and power consumption make this system especially well matched for Tier II UAV applications. EnerlinksII is network ready and disseminates and manages ISR content over any IP network using the EnerView™ client software. Enerdyne products are ideally suited for the net-centric warfare concept of today's military, in which the dissemination of video and other imagery to ground vehicles, foot soldiers, or air platforms is a critical requirement.

Enerdyne government programs include contracts directly with the Department of Defense and other subcontracts with major U.S. defense companies such as Lockheed Martin, L3, and DRS, and international firms such as Tadiran and Rafael. Enerdyne employs 53 people and is based in El Cajon, California (east San Diego County).
