[1] On October 1, 2013, the funding of the purchase of our Tualatin, Oregon corporate offices from Barakel, LLC was completed. The purchase price for this asset was $5,050,000. The purchase was funded, in part, by a promissory note payable to Wells Fargo Bank in the amount of $3,693,750 plus interest at the rate of 2% above LIBOR, payable over ten years with a balloon payment due at maturity. It was secured by a deed of trust on the purchased property which was executed by CUI Properties, LLC and guaranteed by CUI Global, Inc. During the six months ended June 30, 2015, the Company made principal payments of $40 thousand against the mortgage promissory note payable. At June 30, 2015, the balance owed on the mortgage promissory note payable was $3,564,210, of which $82,792 and $3,481,418 were in current and long term liabilities, respectively at June 30, 2015.

[2] The note payable to International Electronic Devices, Inc. (formerly CUI, Inc.) is associated with the acquisition of CUI, Inc. The promissory note is due May 15, 2020 and includes a 5% interest rate per annum, with interest payable monthly and the principal due as a balloon payment at maturity. The note contains a contingent conversion feature, such that in the event of default on the note the holder of the note can, at the holder’s option, convert the note principal into common stock at $0.001 per share. As of June 30, 2015, the Company is in compliance with all terms of this promissory note and the conversion feature is not effective.
