NOTE C – RESTRICTED CASH

As required by the original mortgage loan entered into with Fifth Third Bank (the “Bank”) on July 11, 2008 (see NOTE I), $500,000 was deposited into an additional interest-bearing account from which principal and interest payments are made. On each anniversary of the mortgage, we were required to deposit into the account an amount sufficient to ensure a balance of $500,000 for principal and interest payments for the subsequent year of the mortgage. This mortgage loan matured and was extended during July 2013. This new loan calls for a restricted cash balance of $400,000 to be funded annually. The balance in the restricted cash account is held as additional collateral by the Bank and is not available for operations. The balance in this account at September 30, 2013, was $150,491.

During July 2013, we entered into a $10.0 million project term loan with the Bank (see NOTE I). This loan matures in July 2014. Per the agreement, we deposited, from the loan proceeds, $500,000 into a restricted bank account to cover principal and interest payments. This account balance is also pledged as additional security for the loan. There is no requirement to fund this account in the future.
