Exhibit 99.8 Numerex Purchases Cingular Interest in Cellemetry LLC Includes the Buy-Back of 625,000 Shares of Numerex Common Stock In Conjunction With Purchase of Cingular 40% Minority Interest ATLANTA, March 31 /PRNewswire-FirstCall/ -- Numerex Corp. (Nasdaq: NMRX) today announced the purchase of Cingular's 40% interest in Cellemetry LLC, a joint venture formed in 1998, and the 625,000 shares of Numerex common stock owned by Cingular for $5 million. The Company issued a secured note for $5 million payable through December 15, 2004 in three payments beginning in December 15, 2003 with interest accruing at 8%. The transaction gives Numerex full ownership of Cellemetry LLC and its subsidiary, Uplink Security Inc., while simultaneously reducing Numerex's shares outstanding by 5.5%. "The Cingular transaction clearly underscores our belief in the future of our wireless data business and the viability of our recurring revenue financial model," said Stratton Nicolaides, chairman and CEO of Numerex. "We have set our strategic course with a clear-cut mission of growing our wireless telemetry business with a focus on our direct market drivers, such as Uplink(SM) Security and MobileGuardian(TM). We believe that our end-to-end wireless solutions combined with the network connections added by our value- added resellers and strategic partners, provides Numerex an optimal path to bring real value back into the Company's stock, despite the difficult economic environment. Cingular has been supportive and constructive throughout this several-month negotiating process, and we look forward to continuing our long- standing relationship." The Company is currently seeking to raise capital sufficient to meet its obligations, both for general operational purposes and to meet the agreed upon payment schedule contained in the Cingular transaction. Numerex has secured a line of credit from Alethea Limited Partnership, a company affiliated with its chairman and CEO, Stratton Nicolaides. Alethea has agreed to extend a $1 million line of credit for a period of one year, primarily to be used for working capital purposes at a fixed rate of 10% with no commitments fees, and secured by a pledge of the stock and assets of Digilog, Inc., a Numerex wholly-owned subsidiary. The Company believes that this line of credit should provide it with sufficient liquidity to fund its operations through the balance of the year. The Company also announced that it has retained investment-banking firm Jefferies & Company, Inc. as its financial advisor to assist the Board of Directors in reviewing a range of potential financial and strategic alternatives, including capital raising as well as potential divestitures of non-core assets. The divestiture of these non-core assets are expected to generate additional capital that can be used for both working capital and general corporate purposes, including meeting its debt obligations to Cingular. Of course, there are no assurances that an asset sale will occur or that if a sale occurs it will generate proceeds sufficient to meet its debt obligations.
