The non-payments constitute an event of default under the Indenture governing the Notes. The trustee, by notice to the Company, or the holders of 25% of the principal amount of the Notes outstanding, by notice to the Company and the trustee, may declare the outstanding principal plus interest due and payable immediately. During the continuation of any event which, with notice or lapse of time or both, would constitute a default under any agreement under which Senior Indebtedness is issued, if the effect of such default is to cause or permit the holder of Senior Indebtedness to become due prior to its stated maturity, no payment of principal, premium or interest shall be made on the Notes unless and until such default shall have been remedied, if written notice of such default has been given to the trustee by the Company or the holder of Senior Indebtedness. If the holder of Senior Indebtedness accelerates the due date at any time, then no payment may be made until the default is cured or waived. The Notes are subordinate to all Senior Indebtedness of the Company. As of June 30, 2014, the Company had $334,000 of 9½% Subordinated debentures due 2012 (the “Debentures”) which matured on December 1, 2012; interest was payable semi-annually.

The offer expired on October 31, 2011, but the Company continues to consider further exchanges of the Debentures. $723,000 of the original $1.1 million principal amount of the Debentures have been exchanged, leaving $334,000 outstanding. Based on the payment schedule prior to the offer to exchange, the Company had not remitted the December 1, 2009, 2010 and 2011 sinking fund payments of $106,000 each, the June 1, 2010, 2011 and 2012 and the December 1, 2010 and 2011 semi-annual interest payments of $50,000 each and the December 1, 2012 semi-annual interest and principal payment of $790,000 to the trustee. The non-payments constitute an event of default under the Indenture governing the Debentures. The trustee, by notice to the Company, or the holders of 25% of the principal amount of the Debentures outstanding, by notice to the Company and the trustee, may declare the outstanding principal plus interest due and payable immediately. During the continuation of any event which, with notice or lapse of time or both, would constitute a default under any agreement under which Senior Indebtedness is issued, if the effect of such default is to cause or permit the holder of Senior Indebtedness to become due prior to its stated maturity, no payment (including any required sinking fund payments) of principal, premium or interest shall be made on the Debentures unless and until such default shall have been remedied, if written notice of such default has been given to the trustee by the Company or the holder of Senior Indebtedness. The Debentures are subordinate to all Senior Indebtedness of the Company. As of June 30, 2014, the Company had a $425,000 mortgage on its facility located in Des Moines, Iowa at a fixed rate of interest of 6.50% payable in monthly installments, which matures March 1, 2015 and requires a compensating balance of $200,000.

(“Carlisle”) at a fixed interest rate of 10.00%, which was due to mature on June 1, 2014 with a bullet payment of all principal and accrued interest due at such time, which maturity date was subsequently extended to July 1, 2014. On June 20, 2014, this loan was converted into shares of the Company’s Common Stock at an exchange rate of 1 share for every $6.00 of principal, resulting in the issuance of 166,666 shares of Common Stock to Carlisle. Marco Elser, a director of the Company, exercises voting and dispositive power as investment manager of Carlisle. In connection with the loan, the Company had granted to Carlisle a first-priority (excluding the liens held by the Pension Benefit Guaranty Corporation, which are senior to the liens and security interest granted in connection with the Loan) continuing security interest in and lien upon all assets of the Company (excluding those assets subject to the security interest granted to AXIS Capital, Inc. by the Company pursuant to that certain Master Agreement for Sale and Assignment of Leases dated as of June 2013), in accordance with the terms of a security agreement entered into between the parties and dated as of December 2, 2013.

Schiele, a director of the Company, at a fixed interest rate of 10.00%, which was due to mature on July 1, 2014 with a bullet payment of all principal and accrued interest due at such time.
