          NOTE
          4 – Line
          of Credit
         
          On
          August 1, 2011, the Company entered into a Second Amended
          and Restated Loan Agreement (the “Loan
          Agreement”) with Heartland Bank (the
          “Bank”). The Loan Agreement provides for
          maximum revolving credit borrowings of $2,000,000 with
          the Bank, with borrowings limited to a borrowing base
          determined based on 70% or 80% of eligible accounts
          receivable plus 50% of eligible inventory. Significant
          restrictive covenants in the Loan Agreement include
          prohibitions on any merger, consolidation or sale of all
          or a substantial portion of the Company’s assets
          and limits on the payment of dividends or the repurchase
          of shares. The Loan Agreement does not contain any
          financial covenants that require compliance with ratios
          or amounts.  Dividends and share repurchases
          are permitted as long as after giving effect to the
          dividend or share repurchase the Company has a ratio of
          total liabilities to total stockholders’ equity of
          no more than 1:1.  Borrowings on the revolving
          note bear interest at a rate of the base rate (4.50% at
          June 30, 2012) plus 0.5%. The note is collateralized by
          substantially all of the assets of the Company. No
          amounts were outstanding under the Loan Agreement at June
          30, 2012 or September 30, 2011.  The Company
          expects that the revolving note with the Bank will be
          renewed on August 1, 2012 for a one-year term expiring on
          August 1, 2013 with no other significant change in the
          terms of the facility.
