The Company markets its products and services throughout the world to original equipment manufacturers (OEMs) and systems integrators in the building, industrial, transportation, utility/home, and other automation markets. During the three and nine months ended September 30, 2012 and 2011, the Company had four customers that accounted for a significant portion of its revenues: EBV Electronik GmbH and Avnet Europe Comm VA (“EBV/Avnet”), the Company’s primary distributors of its Sub-systems products in Europe, Duke Energy Corporation (“Duke”), a U.S. utility company; and Eltel Networks A/S (“Eltel”) and Telvent Energia y Medioambiente SA (“Telvent”), value added resellers of the Company’s Systems products. For the three and nine months ended September 30, 2012 and 2011, the percentage of the Company’s revenues attributable to sales made to these customers was as follows:

	Three Months Ended		Nine Months Ended
	September 30,		September 30,
	2012	2011	2012	2011
Telvent	22.0%	15.3%	29.5%	14.4%

In April 2011, the Company’s distributor agreement with EBV was assigned from EBV to Avnet Europe Comm VA, a limited partnership organized under the laws of Belgium (“Avnet”). Each of EBV and Avnet are indirect subsidiaries of Avnet, Inc., a New York corporation, which is a distributor of electronic parts, enterprise computing and storage products and embedded subsystems. At the time of the assignment, the term of the distributor agreement was extended and will now expire in June 2014.
