BORROWINGS

On June 14, 2013, Heartland replaced one of its $5.0 million unsecured revolving lines of credit at an unaffiliated bank with a $20.0 million unsecured revolving line of credit at the same unaffiliated bank, resulting in a total borrowing capacity of up to $25.0 million at any one time. The new agreement matures on June 14, 2014. Heartland had no outstanding balance on its two lines of credit as of June 30, 2013.
