(NYSE Amex: ADGE), a leading On‑Site Utility, offering clean electricity, heat, hot water and cooling solutions to hospitality, healthcare, housing and athletic facilities, today announced that it has agreed to the request of all holders of its Senior Unsecured Convertible Debentures, due 2018 ("Debentures"), to modify the interest payment from cash to shares of the Company's Common Stock. The modification to the interest payment will be for interest paid in 2012, 2013 and 2014.
