The loan was scheduled to mature in December 2013. Also during July 2013, the Company closed on a five-year $400,000 unsecured term loan.

The loan bears interest at a variable rate of LIBOR plus 150 basis points based on the Company's current credit rating and has a maturity date of July 2018. The Company has evaluated subsequent events through the date of issuance of these financial statements.
