Numerex builds UK presence to tap European M2M market growth

Company opens new international business development office in London, and partners with Arkessa, an established UK M2M service provider

ATLANTA, May 16, 2011 - Numerex Corp (NASDAQ: NMRX), a leading single source provider of secure
machine-to-machine (M2M) products and services, today announced the opening
of its London office and a collaboration with Arkessa Limited, to foster
Numerex's advance in the European M2M market. Arkessa, headquartered in
Cambridge, England, is an established presence in the M2M market in the
United Kingdom and provides European systems integrators and major corporate
users with wide area wireless internet connections and services that enable
remote information and management for a multitude of users.

The European M2M market is showing visible signs of rapid improvement,
driven by a favorable regulatory environment and increased awareness of the
technology capabilities. In a recent announcement, International Data
Corporation (IDC) reported that "the European machine-to-machine (M2M) market
is quickly recovering from the economic crisis of 2008-2009 and is starting
to prosper again with growth rates exceeding 12% over the 2010-2015 period"
(IDC press release of February 28, 2011).

Arkessa provides European systems integrators and corporate users with
cellular-based wireless internet connectivity and data services, enabling the
connection, control and management of remote systems and equipment for a
multitude of users across borders and applications. The critical factors
leading to Numerex's selection of Arkessa as a partner in Europe were its
market presence and focus on pervasive, secure, and reliable connectivity,
which allows its users to extract information from the harvested data in
real-time.

"Arkessa provides Numerex with a proven, solid, European presence that
delivers a package of additional data service capabilities coupled with
market reach and insight. Our customers will also benefit from access to
highly reliable and rapidly available M2M turnkey solutions developed
through, by and with Numerex," stated Ian Orrock, Executive Chairman of
Arkessa.

"Through partnerships with wireless carriers and infrastructure
providers, we have built a seamless and ubiquitous M2M development platform,
which has contributed to establishing a robust international service
offering," said Louis Fienberg, Executive Vice President, Corporate
Development of Numerex. "The growing interest in our products and services
received from the UK, and elsewhere in Europe, has led us to strengthen our
presence in that market. With the addition of Arkessa's expertise and our
London office, we are now in a much better position to respond quickly and
effectively to European customers' needs." As an integral part of this
strategic relationship, Numerex has acquired a minority stake in Arkessa.
Funds will be used to support Arkessa's expanding business development
initiatives.

The Numerex UK office is headed by Simon Glassman, a telecommunications
veteran with a broad and deep experience and knowledge of the European M2M
industry acquired with market leaders such as TomTom, Symbian, and Unisys.

The Numerex European expansion will focus on presenting Numerex's
products and services combined with Arkessa's, to the European market, and
developing relationships with European companies interested in extending
their M2M activities using the Numerex platform in the North American market
and beyond.
