DEBT

Mortgages and note payable

We have a term loan from Regions Bank ("Regions") aggregating approximately $5,403 at June 30, 2013 and $5,842 at September 30, 2012, which is secured by mortgages on our facilities in West Lafayette and Evansville, Indiana.

On November 29, 2010, we executed amendments on two loans with Regions. As part of the amendments, we agreed to a $500 principal payment on one of the loans and a $500 principal payment on the other loan in exchange for certain modifications to the financial covenants in the loan agreements described below. The principal payments were made on December 17, 2010 and February 11, 2011, respectively. Upon receipt of these two payments, Regions incorporated the two loans into a replacement note payable for $1,341 maturing on November 1, 2012. The replacement note payable bore interest at a per annum rate equal to the 30-day LIBOR plus 300 basis points (minimum of 4.5%) with monthly principal payments of approximately $14 plus interest. The replacement note payable was secured by real estate at our West Lafayette and Evansville, Indiana locations.

As part of the amendment, Regions also agreed to amend the loan covenants for the related debt to be more favorable to us. Regions requires us to maintain a fixed charge coverage ratio of not less than 1.25 to 1.00 and a total liabilities to tangible net worth ratio of not greater than 2.10 to 1.00. At June 30, 2013, we were in compliance with the fixed charge coverage and the total liabilities to tangible net worth ratios in the Regions agreements. Failure to comply with those covenants in future quarters would be a default under the Regions loans, requiring us to negotiate with Regions regarding loan modifications or waivers. If we are unable to obtain such modifications or waivers, Regions could accelerate the maturity of the loans and cause a cross default with our other lender.

On November 9, 2012, we executed a sixth amendment with Regions which we further modified on December 21, 2012. In the sixth amendment, Regions agreed to extend the term loan and mortgage loan maturity dates to October 31, 2013. The unpaid principal on the notes was incorporated into a replacement note payable for $5,786 bearing interest at LIBOR plus 400 basis points (minimum of 6.0%) with monthly principal payments of approximately $47 plus interest. The replacement note payable is secured by real estate at our West Lafayette and Evansville, Indiana locations. At June 30, 2013, the replacement note payable had a balance of $5,403.

The Regions loan agreement contains cross-default provisions with the revolving line of credit with Entrepreneur Growth Capital LLC ("EGC") described below.

The replacement note payable with Regions matures in the first quarter of fiscal 2014. We intend to refinance the amounts in lieu of making balloon payments for the remaining principal balances or sell the building in West Lafayette, Indiana. On July 12, 2012, we listed for sale our 7.25 acres and 120,000 square foot facility at 2701 Kent Avenue, West Lafayette, Indiana with the intent to leaseback 80% of that square footage in which to continue our laboratory and manufacturing operations. We enlisted a new realtor in our third fiscal quarter and changed the asking price to $10,800. We performed an impairment analysis on the building when we listed it for sale, but noted no impairment necessary. As of June 30, 2013, the net book value of the facility and land was $9,333.

We may be unsuccessful in renegotiating the terms of the debt or those terms may be unfavorable to us. For these reasons, if we are unsuccessful at refinancing our long-term debt, our operating results and financial condition could be adversely affected.

Revolving Line of Credit

We have a $3,000 revolving line of credit agreement ("Credit Agreement") with EGC. The term of the Credit Agreement expires on January 31, 2014. If we terminate prior to the expiration of the term, then we are subject to an early termination fee equal to the minimum interest charge of $15 for each of the months remaining until expiration.

Borrowings under the Credit Agreement bear interest at an annual rate equal to Citibank's Prime Rate plus five percent (5%), or 8.25% as of June 30, 2013, with minimum monthly interest of $15. Interest is paid monthly. The line of credit also carries an annual facilities fee of 2% and a 0.2% collateral monitoring fee. Borrowings under the Credit Agreement are secured by a blanket lien on our personal property, including certain eligible accounts receivable, inventory, and intellectual property assets, a second mortgage on our West Lafayette and Evansville real estate and all common stock of our U.S. subsidiaries and 65% of the common stock of our non-United States subsidiary. Borrowings are calculated based on 75% of eligible accounts receivable. Under the Credit Agreement, the Company has agreed to restrict advances to subsidiaries, limit additional indebtedness and capital expenditures and maintain a minimum tangible net worth of at least $8,500. Pursuant to the terms of the Credit Agreement, the line of credit will automatically renew on January 31, 2014 unless either party gives a 60-day notice of intent to terminate or withdraw.

On December 21, 2012, we negotiated an amendment to this Credit Agreement. The amendment reduced the minimum tangible net worth covenant requirement from $8,500 to $8,000, effective on January 1, 2013, and waived all non-compliances with this covenant through December 31, 2012. At June 30, 2013, we were in breach of the minimum tangible net worth covenant requirement due to the reclassification of the Class A Warrants to a liability from equity as discussed in Note 2. On October 9, 2013, EGC waived compliance with the tangible net worth covenant for our current quarter.

The Credit Agreement also contains cross-default provisions with the Regions loan and any future EGC loans.

At June 30, 2013, we had available borrowing capacity of $1,556 on this line, of which $332 was outstanding. At September 30, 2012, we had available borrowing capacity of $1,927 on this line, of which $1,444 was outstanding.
