~~Results~~On October 23, 2017, Numerex Corp. ("Numerex") and Sierra Wireless, Inc. ("Sierra Wireless") received notice from the U.S. Federal Trade Commission that it had granted early termination, effective immediately, of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR Act"), for the previously announced acquisition of Numerex by Sierra Wireless pursuant to an Agreement and Plan of Merger by and among Numerex, Sierra Wireless and Wireless Acquisition Sub, Inc. dated August 2, 2017 (the "Merger Agreement"). The early termination of the HSR Act satisfies one of the conditions to the closing of the pending acquisition, which remains subject to other customary closing conditions, including the adoption of the Merger Agreement by Numerex's shareholders. Important Additional Information and Where to Find It. This communication may be deemed to be solicitation material in respect of ~~Operations~~the proposed acquisition of Numerex by Sierra Wireless. In connection with the proposed Merger, Sierra Wireless has filed with the United States Securities and ~~Financial~~Exchange ~~Condition~~Commission (the "SEC") a registration statement on Form F-4, which includes a proxy statement of Numerex that also constitutes a prospectus of Sierra Wireless and each party has filed and will file other documents regarding the proposed transaction with the SEC. After the registration statement on Form F-4 is declared effective by the SEC, Numerex will mail the proxy statement/prospectus to its shareholders. BEFORE MAKING ANY VOTING OR INVESTMENT DECISION, INVESTORS ARE URGED TO READ THE PROXY STATEMENT/PROSPECTUS (INCLUDING ALL AMENDMENTS AND SUPPLEMENTS THERETO) AND OTHER RELEVANT DOCUMENTS FILED WITH THE SEC CAREFULLY AND IN THEIR ENTIRETY IF AND WHEN THEY BECOME AVAILABLE BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT THE PROPOSED MERGER AND RELATED MATTERS.

Participants in Solicitation Relating to the Merger This communication is not a solicitation of proxies in connection with the proposed Merger of Numerex and Sierra Wireless. However, Sierra Wireless, Numerex and its directors and executive officers may be deemed to be participants in the solicitation of proxies from Numerex's shareholders in respect of the proposed Merger. Information regarding Sierra Wireless' directors and executive officers can be found in Sierra Wireless' Form 40-F filed with the SEC on March 10, 2017, as well as its other filings with the SEC.
