Sierra Wireless Announces Sales Management Changes

Vancouver, B.C.-September 21, 2005
Sierra Wireless (NASDAQ: SWIR - TSX: SW) today announced the changes to the company's sales team to focus on key customer relationships. Jim Lahey has recently been promoted to Vice President for Europe, the Middle East, and Africa region (EMEA). This follows the appointments earlier this year of Mike Ardelan to the position of Vice President, North American Enterprise and OEM Sales, and Mike O'Brien to the position of Vice President, Carrier and Distribution Sales for the Americas.

"These focused sales teams will allow us to better serve our key customers in both the Americas and the EMEA region. In the Americas, this translates to a dedicated team for carriers and distributors, led by Mike O'Brien, and a dedicated team for our original equipment manufacturer (OEM) and enterprise accounts, led by Mike Ardelan," said Dan Schieler, Senior Vice President of Worldwide Sales for Sierra Wireless. "In the EMEA region, under the leadership of Jim Lahey, we have deployed the team to provide regional support to customers, with representatives in the United Kingdom, France, Italy, Germany, and the Middle East."

Jim Lahey joined Sierra Wireless in 1999 as Director, OEM Sales, and relocated to the London office in 2001 as Director of Business Development. Jim has more than 20 years of business development and sales experience, and has spent the last 12 years of his career in the wireless data industry. Prior to joining Sierra Wireless, Jim was Director, OEM Sales with Aironet Wireless Communication, and spent seven years with Motorola in wireless sales and business development, including an assignment as OEM Business Development Director with the Motorola Wireless Data Group.

Mike Ardelan joined Sierra Wireless eight years ago as Director for the Alliance Partner Program, and later became Director of Business Development for Embedded Module Sales. He made the first OEM sales in the company's history and was largely responsible for building the company's current OEM customer portfolio. Mike has 16 years of sales experience in the wide area wireless data industry, encompassing mobile devices, client applications, communications tools, and professional services.

Mike O'Brien joined AirPrime (acquired by Sierra Wireless in 2003) more than five years ago as Regional Sales Director, and was later promoted to Director, Strategic Partner Sales.
