Nigeria's Starcomms Evolves to All-IP Next-Gen Network With PT's SEGway(TM) Solution

Highly Reliable and Flexible Architecture Primes Carrier for Upcoming Regulatory Requirements

ROCHESTER, New York, July 28, 2010 - PT (Nasdaq: PTIX), the recently rebranded Performance Technologies, a
leading global provider of advanced network communications solutions, today
announced that its SEGway(TM) Signalling Solution was selected to upgrade
Starcomms' network in Nigeria. A full service CDMA carrier in the country,
Starcomms serves 3.2 million customers in Nigeria with mobile services,
Internet broadband services, and fixed wireless services.

A leader in its field, Starcomms is the first telecommunications operator
in Nigeria to be listed publicly on the domestic stock exchange, and states
'PRIDE' as its key corporate value. Ever forward thinking and responsible to
its subscribers, Starcomms is transitioning its network to a complete IP
architecture. The carrier designed a hierarchical network topology using PT's
SEGway signalling solution at the core, which allows effortless
interconnection of IP elements to existing equipment.

SEGway's highly reliable and efficient solution reduces signalling
complexity and provides the ability to view and manage the network from a
central location. The robust platform provides a single point of interconnect
with other networks, and centralized administration of routing, resulting in
the most cost-effective transport between cities. This technology avoids all
the inherent pitfalls of legacy mesh networks, such as single points of
failure, signalling traffic congestion, and costly operations,
administration, and management.

"It is paramount to us that we work with a supplier that possesses
exceptional SS7 expertise," said Trino Guzman, head of Engineering from
Starcomms. "PT's technology delivers exceptional performance, and their team
made our network migration easy, transparent, and seamless. PT meets our high
standard of pride when it comes to top performance."

"PT's versatile signalling platform places the core network in an
advantageous position with regard to the looming number portability
regulation in Nigeria," said Patt Rice, senior vice president, Sales,
Marketing, and Service for PT. "SEGway enables any operator to quickly,
efficiently, and seamlessly introduce Mobile Number Portability to meet the
December 2010 deadline."

PT's state-of-the art SEGway platform is a highly reliable signalling
system that provides operators a smooth migration to IP and SIP
Next-Generation Networks. In addition to number portability, it enables
message accounting, and advanced routing.

John Slusser, PT president and chief executive officer, commented, "We
are most pleased to add Starcomms, a highly regarded, progressive service
provider, to our SEGway installed base. These are exciting yet challenging
times for African telecommunications operators as they anticipate substantial
subscriber growth and evolution to more advanced networks. PT has made a
strategic commitment to the region with leading edge network solutions backed
by unsurpassed service and support."
