COM DEV's exactEarth And Spain's HISDESAT Join Forces To Tackle The Space-Based AIS Market

HISDESAT Makes Strategic Investment in exactEarth - Adds Global Market Strength

CAMBRIDGE, Canada, September 30, 2010 - COM DEV International Ltd. (TSX:CDV), a leading manufacturer of space
hardware subsystems, today announced that its data services subsidiary,
exactEarth Ltd. ("the Company"), has added a strategic investor that will
play an important role in delivering and growing the Company's exactAIS(TM)
service in the marketplace. HISDESAT Servicios Estrategicos S.A., a major
Madrid-based satellite operator and service provider that sells data to more
than 25 government customers around the world, has taken a 27% equity
interest in exactEarth with a cash investment of CDN $15 million, which
represents an implied $55.5 million valuation of the exactEarth business. The
cash investment will support exactEarth's on-going business operations and
the deployment of additional space and ground infrastructure.

"We are excited to have access to HISDESAT's data services expertise and
global market reach," said Peter Mabson, President of exactEarth Ltd. "These
strengths are complementary with COM DEV's strengths in satellite technology
and are very well aligned with our needs at exactEarth as we roll out AIS
data services into the international marketplace. HISDESAT's investment
follows closely on the heels of our successful service launch last month and
confirms our commitment and ability to deliver a premium quality and highly
reliable space-based AIS data service to the global market."

In addition to its investment in exactEarth, HISDESAT will play a
strategic role in supporting the Company's operations and service delivery.
HISDESAT will represent exactEarth as a reseller in a wide range of market
territories where they have an established market presence. In addition to
this, it is expected that HISDESAT will operate a second data center in
Europe on behalf of the exactEarth business, in a move that will further
improve the overall reliability of the exactEarth global AIS system.

"We view our strategic investment in exactEarth as a long-term commitment
to support our business interests in global surveillance," said Roberto Lopez
Fernandez, Chief Executive Officer of HISDESAT. "We have spent considerable
time evaluating the exactEarth AIS technology and the Company's business
plan, and have concluded that both are well aligned with our objectives. It
was a logical next step to participate in this opportunity directly through
an equity investment. We are pleased to be strategically aligned with COM DEV
in capitalizing on the Space-based Maritime Surveillance opportunity this
technology represents. There is a lot of potential for exactEarth, and we
believe in its future."

"The HISDESAT partnership is an ideal one for exactEarth," said Michael
Pley, Interim CEO of COM DEV. "HISDESAT offers highly complementary expertise
and customer relationships at a crucial time for the Company, as it commences
commercial operations of its space-based AIS data services business. The
extended market access that HISDESAT brings to the Company is a significant
strategic benefit, and augments the sales and marketing reach that exactEarth
has successfully achieved on its own. Attracting such a well known and
experienced satellite operations and space data service company as an
investor speaks volumes in support of the potential of exactEarth's business.
We welcome HISDESAT as a strategic partner and look forward to a very strong,
enduring, and successful partnership with them."

The HISDESAT transaction, which closed today, implies a post-money
valuation of approximately $55.5 million for exactEarth. At the end of the
most recent fiscal quarter the Company was valued at approximately $16
million on COM DEV's consolidated balance sheet. COM DEV has committed to
funding $35 million of the Company's capital and operating expenses, of which
approximately $24 million has been provided to date. COM DEV retains
ownership of 73% of exactEarth. (All amounts are stated in Canadian dollars.)
