Numerex and Savi to Launch GlobalTag Combining GPS, RFID and Satellite Communications

Atlanta, 02/17/2009 -- Numerex Corp. (NASDAQ: NMRX) and Savi, a Lockheed Martin [NYSE: LMT] company, today announced their technology partnership to co-develop what would be the first asset and shipment monitoring device that combines Global Satellite Positioning, active Radio Frequency Identification and Satellite Communications. The hybrid ST-694 GlobalTag is being developed to provide continuous monitoring and precise location information of assets most anywhere and anytime for defense, public sector and commercial customers.

The ST-694 will provide a new cost-effective solution to a growing market demanding new capabilities for both spot-level and ongoing in-transit visibility of their shipments and mobile supply chain assets, such as transport vehicles, container shipments or large and valuable equipment. The solution leverages Numerex's strength as a leading provider of full-service, highly secure M2M (Machine-to-Machine) network services and solutions and Savi's premier capabilities in providing a full range of integrated Automatic Identification Technology (AIT) product solutions for supply chain visibility, management and security.

"Savi provides a leading-edge technology behind the world's largest RFID network in place today," said Mike Marett, chief operating officer, Numerex Corp. "We believe that this powerful combination of expertise and automated technologies will advance supply chain monitoring and management capabilities from origin to final destination, resulting in higher levels of value for our customers."

"We decided to partner with Numerex on this innovative solution because of the company's success in deploying reliable satellite technologies in the emergency management industry," said David Shannon, Savi Technology's senior vice president of Product Management, Marketing and Strategy. "Our collaboration will benefit any government agency, department, or supply chain professional in need of a truly transparent, integrated tracking solution than can span across existing RFID networks and into areas where traditional active RFID infrastructure is not practical. This will deliver improved, seamless visibility throughout the supply chain regardless of physical location."

The satellite-based global RFID device will be designed to provide tracking information in the harshest environmental conditions, be scalable, flexible, and deliver real-time visibility to those who need it, on a near global basis. The partners will work together to ensure that the ST-694 GlobalTag becomes HERO (Hazards of Electromagnetic Radiation to Ordnance) certified, and based on the ISO 18000-7 standard for active RFID, which will help promote interoperability with compatible networks and devices.

Savi has provided the active RFID products for the U.S. DoD's In-Transit Visibility network, which is the world's largest RFID network that tracks about 35,000 conveyances daily across more than 4,000 locations and 40 countries. Asset owners, chemical, retail, defense, transportation companies, rail, suppliers faced with customer RFID mandates, ocean ports and terminal operators, exporters, importers and logistics service providers benefit from Savi's real-time solutions.

Numerex's satellite products support firefighting, hurricane relief operations, and other situations that benefit from an immediate highest ground perspective. Utilizing satellite technologies for emergency management organizations in need of general field logistics capabilities, Numerex delivers tracking solutions tailored to various industries from cargo tracking to defense logistics.
