Holocom Announces New PDS Design Patent

(SAN DIEGO - February 11, 2009) Holocom, the leading provider of proprietary
high-security protective distribution systems (PDS) for SIPRNet and other classified
networks, today announced its newest patent for the Holocom PDS. Pat. D580,871 is
the sixth patent granted Holocom for its PDS, a system currently installed for all
branches of the US military, domestically and internationally. Holocom made the
announcement at the Armed Forces Communications and Electronics Association
(AFCEA) WEST 2009 Conference.

The new patent describes the Retrofit Insert (RTF), a labor-saving accessory that fits
into the 764 end-user drop box. This new addition to the Holocom PDS product suite is
constructed of powder coated 16-gauge, electro-galvanized steel and improves
installation efficiency by eliminating the need to order and install surface mount boxes inside the 764. The RTF, which includes an integrated tension relief cable management wrap, reduces installation time and provides a cleaner look inside the secure enclosure.

"As SIPRNet use expands, Holocom continually looks for ways to reduce the costs
associated with its implementation. We have a tradition of creating products from an
installer's point of view, and this focus drives the development of labor-saving designs such as this," said John Burns, president & CEO of Holocom.

The other five patents for the Holocom PDS extend to the entire system design as well
as specific technology including: eliminating RF leakage within the PDS, the internal
locking mechanism for raceway cover retention, the interlocking mechanism enabling
future moves, adds and changes, and spacers that stand the raceway off the wall.
