8. DEBT

In May 2011 the Company amended and extended its senior secured revolving credit facility ("Revolver") providing for loans of up to $140 million (subject to a borrowing base). This facility is used to finance various ongoing capital needs of the Company as well as for other general corporate purposes. The Revolver matures on December 31, 2015 and will have no financial covenants unless availability (defined as the borrowing base, less actual borrowings and letters of credit) is less than $20 million on any day or less than $25 million for five consecutive business days; otherwise a minimum EBITDA test would apply. The Revolver limits the Company's ability to pay dividends if availability, after adjustment on a pro forma basis for such payment, is less than $30 million. Notwithstanding this limit, the Company can pay up to $2 million of dividends per year. Minimum availability during fiscal 2011 was $30.2 million. The facility is secured by the Company's cash and cash equivalents, accounts receivable, inventory, certain investments and certain plant, property, and equipment. All subsidiaries of the Company are borrowers or guarantors under the facility. At September 30, 2011 the Company had $81.8 million outstanding under the revolving credit facility with a fair value of $81.0 million.

In December 2011, the Revolver was amended to include a provision to modify the minimum EBITDA financial covenant subject to an availability trigger, until the earlier of April 15, 2012 or such time as availability exceeds $50 million. The amendment includes an additional provision which has the effect of reducing the amount available to borrow under the borrowing base formula by $10 million while the modified EBITDA covenant is in effect. The amendment also prohibits the payment of dividends while the modified EBITDA covenant is in effect.

The Company did not furnish audited financial statements for the fiscal year ended September 30, 2011 to the agent within 90 days of year end as required in the credit agreement because the audited financial statements of LSR were not yet available. The Company has obtained a waiver and extension of this requirement.

Interest rates on the amended Revolver are LIBOR plus a margin that varies (with liquidity as defined) from 2.25% to 3.25%, or the base rate (Bank of America prime rate) plus a margin of 1.00% to 2.00%.

Although the final maturity of the Revolver is December 31, 2015, the Company classifies debt under the Revolver as current, as the agreement contains a subjective acceleration clause which can be exercised, if, in the opinion of the lender, there is a material adverse effect, and provides the lenders direct access to our cash receipts.

Cash paid for interest on debt and other long-term liabilities was $2.3 million, $1.5 million and $1.7 million for the years ended September 30, 2011, 2010 and 2009, respectively.
