NOTE 16 — SUBSEQUENT EVENTS
     Subsequent to June 30, 2011, the Company acquired several businesses. While the terms, price, and conditions of each of these acquisitions were negotiated individually, consideration to the sellers typically consists of a combination of cash, our common stock, and issuance of debt. Aggregate consideration paid for these acquired businesses was approximately $21.0 million consisting of approximately $14.3 million in cash, 815,726 shares of our common stock, and issuance of promissory notes of approximately $2.1 million.
      In August 2011, the Company entered into agreements to provide borrowings of up to $37.5 million that would be collateralized by the Waste segment’s vehicles and containers and the Company’s technology and related equipment. In connection with these financing agreements, the Company entered into an amendment that modifies the covenants contained in the credit facility, including an increase in permitted indebtedness to $40.0 million. In addition the Company obtained additional financing of up to $25 million for new and replacement vehicles for its fleet.
