The Company has not remitted the March 1, 2010 and 2011 and September 1, 2010 semi-annual interest payments of $417,800 each to the trustee. The non-payments constitute an event of default under the Indenture governing the Notes and 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. When such notice is received by the Company, no payment shall be made by the Company to the holders or trustee until the earlier of such non-payment event of default is cured or waived or 179 days since receipt by the trustee of notice of such event, unless the holder of Senior Indebtedness has accelerated the due date thereof. 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. At June 30, 2011, the total principal amount outstanding under the Notes is classified as Current portion of long-term debt in the Condensed Consolidated Balance Sheets. The Company’s Board of Directors recently approved a proposed comprehensive restructuring package which includes an offer to the holders of the Notes - $225 plus 250 shares of the Company’s Common Stock for each $1,000 Note offered. The offer will expire on August 31, 2011 and there can be no assurance that any or all of the holders of the Notes will participate. The Common Stock offered in exchange for the Notes will not and have not been registered under the Securities Exchange Act of 1933, as amended, and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements. The Company has $1.1 million of 9½% Subordinated debentures due 2012 (the “Debentures”) which are due in annual sinking fund payments of $105,700 beginning in 2009, which payments have not been remitted by the Company, with the remainder due in 2012; interest is payable semi-annually and the Debentures may be redeemed, in whole or in part, at par. The Company has not remitted the June 1, 2010 and 2011 and December 1, 2010 semi-annual interest payments of $50,200 each to the trustee. The non-payments constitute an event of default under the Indenture governing the Debentures and 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 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 failure to make the sinking fund and interest payments are events of default under the Credit Agreement and no payment can be made to such trustee or the holders at this time as such defaults have not been waived. At June 30, 2011, the total principal amount outstanding under the Debentures is classified as Current portion of long-term debt in the Condensed Consolidated Balance Sheets. The Company’s Board of Directors recently approved a proposed comprehensive restructuring package which includes an offer to the holders of the Debentures - $100 for each $1,000 Debenture offered. The Debentures are subordinate to the claims of the holders of the Notes and the Company’s senior lender under the Credit Agreement, among other senior claims. The offer will expire on August 31, 2011 and there can be no assurance that any or all of the holders of the Debentures will participate. The Company has a bank Credit Agreement, as amended, which provides for a term loan of $10.0 million, a non-revolving line of credit of up to $6.2 million (which is no longer available) to finance the redemption of one-half of the 7½% Subordinated notes due 2006 (which were redeemed in June 2006 and are no longer outstanding), and a revolving loan of up to $4.3 million, based on eligible accounts receivable and inventory, at a variable rate of interest of Prime plus 2.00%, with a floor of 6.00% (6.00% at June 30, 2011), which was due to mature May 1, 2011. In May 2011, the senior lender agreed to extend the maturity date of the Credit Agreement to November 1, 2011, remove the senior debt coverage ratio covenant for the March 31, 2011 and June 30, 2011 periods and waived the December 31, 2010 non-compliance of the senior debt coverage ratio. In 2010, the senior lender modified the monthly principal payments, modified the maturity date of the Credit Agreement and reduced the availability under the revolving loan from $5.0 million to $4.3 million. As of June 30, 2011, the Company has drawn $3.8 million against the revolving loan facility, of which $0.1 million was available for additional borrowing. The Credit Agreement requires an annual facility fee on the unused commitment of 0.25% and requires compliance with certain financial covenants, as defined in the Credit Agreement, which include a loan-to-value ratio of not more than 50% and a quarterly $1.0 million cap on capital expenditures. As of June 30, 2011, the Company was in compliance with the foregoing financial covenants. The senior lender has waived the cross-defaults in connection with the Notes and the Debentures, but in the event that the holders of the Notes or the Debentures or trustees declare a default and begin to exercise any of their rights or remedies in connection with the non-payment defaults, this shall constitute a separate and distinct event of default and the senior lender may exercise any and all rights or remedies it may have. In addition, the senior lender has waived the default of non-payment of certain pension plan contributions, but in the event that any government agency takes any enforcement action or otherwise exercises any rights or remedies it may have, this shall constitute a separate and distinct event of default and the senior lender may exercise any and all rights or remedies it may have. The amounts outstanding under the Credit Agreement are collateralized by all of the Display division assets. On June 17, 2011, the Company entered into a subscription agreement for a private placement consisting of $650,000 of 4.00% secured notes of the Company pursuant to Section 4(2) of the Securities Act of 1933, as amended, and Rule 506 promulgated thereunder. In connection with the purchase of these notes, the subscriber received a five-year warrant (the “Warrant”) to purchase 1,000,000 shares of Common Stock of the Company at an exercise price of $1.00, subject to adjustment as provided in the Warrant. The financing is collateralized by the land held for sale located in Silver City, New Mexico. On March 1, 2010, the Company refinanced its existing mortgage on its facility located in Des Moines, Iowa. The refinancing was for $650,000 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. The Company used proceeds of $390,000 to settle the prior debt and used the $260,000 balance for working capital needs. The Company has a $1.8 million mortgage on its real estate rental property located in Santa Fe, New Mexico at a variable rate of interest of Prime, with a floor of 6.75%, which was the interest rate in effect at June 30, 2011, payable in monthly installments, which matures December 12, 2012.
