Starhome Files Patent Infringement Lawsuit

ZURICH, June 2, 2010 - Starhome(R), the leading provider and acknowledged driving
force of roaming services for mobile network operators, today announced that
it has filed a patent infringement lawsuit against Roamware, Inc., AT&T
Mobility LLC and T-Mobile USA, Inc., in the United States District Court for
the District of Delaware.

Starhome's Complaint alleges infringement of Starhome's
patents by defendants' provision of international roaming wireless telephone
services to subscribers and telecommunications companies. The Complaint
accuses the defendants of infringing United States Patents 6,920,487 and
7,231,431, each entitled "System and Methods for Global Access to Services
for Mobile Telephone Subscribers." Starhome is seeking damages and a judgment
enjoining further infringement.

"Starhome's products and services provide innovative wireless
mobility solutions to enhance international roaming," said Neta Bloch,
General Counsel of Starhome. "Starhome appreciates the significant value our
patents confer to our business and intends to aggressively protect our
rights."

The Patents cover the core technology of the Starhome(R)
Intelligent Call Assistant(R) (ICA) solution and the Starhome(R) Home Short
Code(TM) (HSC) solution, among other services.

The Starhome HSC solution is one of the first and most
fundamental roaming solutions of the VHE (virtual home environment) concept.
The seamless, feature-rich solution can convert unrecognized home short codes
into valid phone numbers and provide mobile operators with a basis to
increase their revenue potential from both the inbound and outbound
international roaming market.

The Starhome ICA supplements the HSC solution. ICA overcomes
international dialing difficulties by automatically correcting or completing
misdialled numbers. As the majority of these calls are never redialed, ICA
significantly increases roaming revenues for operators. ICA has a rich user
interface that, among other capabilities, can allow combinations of seamless
call completion, native-language voice interaction and post-dialing SMS
notification, and support for prepaid or postpaid communities with respect to
both inbound and outbound roamers.

Eitan Achlow, CEO of Starhome explained: "Over the course of
the last 10 years, Starhome has spent a considerable amount of time and
resources in developing the Home Short Code and the Intelligent Call
Assistant solutions, both of which are included in our patent-protected
portfolio. Starhome invests heavily in intellectual property and realizes the
importance of protecting these innovations and technology."
