Exhibit 99.3

Numerex Corp
Unaudited Pro Forma Financial Information

July 31, 2007, Numerex Corp. (Numerex) through it subsidiary, Orbit One Communications, LLC completed the acquisition of the assets of Orbit One Communications, Inc (“OOCI”). The unaudited pro forma combined condensed consolidated balance sheet as of June 30, 2007 assumes that the acquisition occurred on June 30, 2007 rather than the actual closing date of July 31, 2007. The unaudited pro forma combined consolidated statements of operations for the six months ended June 30, 2007 and for the twelve months ended December 31, 2006 assumes that the acquisition occurred on January 1, 2006 and January 1, 2005 respectively.

The unaudited pro forma information is based on the historical consolidated financial statements of Numerex and those of OOCI, as described in the pro forma financial statements, under the purchase method of accounting and the adjustments as described in the accompanying notes to the unaudited pro forma combined condensed consolidated financial statements. The pro forma combined condensed consolidated balance sheet, statements of operations and accompanying notes are qualified in their entirety and should be read in conjunction with the historical consolidated financial statements and accompanying notes in Numerex’s annual report on Form 10-K and OOCI’s audited consolidated financial statements for the period ended December 31, 2006 which are incorporated herein as Exhibit 99.1.

These proforma financial statements reflect actual cash paid of $5.5 million as well as associated transaction costs for the acquisition of the assets of OCCI. They do not reflect any subsequent payments which could include additional cash payments of $2.5 million. Additionally, upon achievement of certain revenue and EBITDA performance objectives and milestones, Orbit One is entitled to earn-out payments of up to 1,100,000 shares of the Company’s Class A common stock. If the performance targets are exceeded, Orbit One may receive up to an additional 471,729 shares of the Company’s Class A common stock and an additional cash payment of $2.5 million. The earn-out milestones are measured over three periods: (i) from the closing date of the transaction through December 31, 2007; (ii) calendar year 2008; and (iii) calendar year 2009. The Company and Orbit One entered into an escrow agreement, whereby 10% of the cash payments not subject to performance-related milestones were placed in escrow for one year from the closing date in order to settle any indemnification claims under the Agreement and subject to the limitations described therein. Any additional payments of either cash or equity will be reflected as incremental goodwill.

The unaudited pro forma combined condensed consolidated financial statements presented are for informational purposes only and do not purport to represent what Numerex’s financial position or results of operations would have been as of the date or for the period presented had the acquisition in fact occurred on such date or at the beginning of the period indicated, or to project Numerex’s financial position or results of operations for any future date or period. For purposes of preparing Numerex’s consolidated financial statements subsequent to the acquisition, Numerex will establish a new basis for the assets and liabilities of Orbit One Communications, LLC based upon the fair values thereof and Numerex’s purchase price, including the costs of the acquisition. A final determination of the allocation of the purchase price to the assets acquired and liabilities assumed based on their respective fair values has not yet been completed. Accordingly, the purchase accounting adjustments made in connection with the development of the unaudited pro forma combined condensed consolidated financial statements are preliminary and have been made solely for purposes of developing such unaudited pro forma combined condensed consolidated financial statements. As a result of these factors, the actual financial position and results of operations will differ, perhaps significantly, from the pro forma amounts reflected herein. The unaudited pro forma combined condensed consolidated financial statements should be read in conjunction with the historical consolidated financial statements of Numerex and OOCI, including the related notes thereto.
