5.     LOAN PAYABLE:

As of September 30, 2012, PA-1, the Company's wholly-owned subsidiary, owes $7,754,000 under the terms of the Pennvest Loan related to the construction of the Kreider 1 System. The terms of the Pennvest Loan provide for funding of up to $7,754,000 which is to be repaid by interest-only payments for three years, followed by an additional ten-year amortization of principal. The Pennvest Loan accrues interest at 2.547% for years 1 through 5 and 3.184% for years 6 through maturity. The Pennvest Loan requires minimum annual principal payments of approximately $574,000 in fiscal year 2013, $704,000 in fiscal year 2014, $723,000 in fiscal year 2015, $741,000 in fiscal year 2016, $760,000 in fiscal year 2017 and $4,252,000 thereafter. The Pennvest Loan is collateralized by a pledge of all revenues generated from Kreider 1 including, but not limited to, revenues generated from nutrient reduction credit sales and by-product sales. In addition, in consideration for the excess credit risk associated with the project, Pennvest is entitled to participate in the profits from Kreider 1 calculated on a net cash flow basis, as defined. For the three months ended September 30, 2012 and 2011, the Company has incurred interest expense related to the Pennvest Loan of $49,374 and $45,644, respectively, of which $15,793 and $43,650, respectively, has been capitalized as a cost of the Kreider 1 System.

In connection with the Pennvest Loan, the Company provided a “technology guaranty' regarding nutrient reduction performance of Kreider 1 which was structured to expire when Kreider 1's nutrient reduction performance had been demonstrated. On August 1, 2012 the Company informed Pennvest that the Kreider 1 System had surpassed the requisite performance criteria and that, as a result, the Company's “technology guaranty' had been met.
