8. Long-Term Debt

On March 30, 2010, we entered into the Fourth Amended and Restated Credit Agreement (the “Fourth Amended Credit Agreement”). The Fourth Amended Credit Agreement provides us with the 2013 Revolving Credit Facility which is a $345.0 million revolving credit facility that expires December 1, 2013 and includes a swingline sub facility of $20.0 million and a $75.0 million sub facility for letters of credit. The Fourth Amended Credit Agreement also provides a continuation of the term loan facility provided pursuant to the Third Amended and Restated Credit Agreement, of which $190.0 million remained outstanding on December 31, 2011, and an uncommitted incremental accordion facility of $200.0 million. As of December 31, 2011, availability under the 2013 Revolving Credit Facility totaled $125.0 million as calculated under the most restrictive covenant.

Revolving advances under the 2013 Revolving Credit Facility generally bear interest, at our option, at 1) LIBOR plus a spread of 1.875% to 2.750% or 2) the greater of the federal funds rate plus 0.5%, or the prime rate, plus a spread of 0.375% to 1.250%. Term loan borrowings bear interest, at our option, at 1) LIBOR plus 1.50% or 2) the greater of the federal funds rate plus 0.5%, or the prime rate. See Note 6 for a description of our interest rate swap agreements. The Fourth Amended Credit Agreement also provides for a fee ranging between 0.275% and 0.425% of the unused commitments under the 2013 Revolving Credit Facility. The Fourth Amended Credit Agreement is secured by guarantees from most of the Company's domestic subsidiaries and by security interests in substantially all of the Company's and such subsidiaries' assets.

We are required to repay outstanding revolving loans under the 2013 Revolving Credit Facility on December 1, 2013. We are required to repay term loans in quarterly principal installments aggregating $0.5 million each, which commenced on March 31, 2007. The entire unpaid principal balance of the term loans is due and payable at maturity on December 1, 2013.

The following table summarizes the minimum annual principal payments and repayments of the revolving advances under the Fourth Amended Credit Agreement for each of the next five years and thereafter:

2014		-

The Fourth Amended Credit Agreement contains various financial covenants, which require us to maintain, as defined, ratios or levels of 1) total funded debt to EBITDA, 2) fixed charge coverage, and 3) net worth. The Fourth Amended Credit Agreement also restricts the payment of dividends and limits the amount of repurchases of the Company's common stock. As of December 31, 2011, we were in compliance with all of the covenant requirements of the Fourth Amended Credit Agreement.

As described in Note 6 above, as of December 31, 2011, we are a party to interest rate swap agreements for which we receive a variable rate of interest based on LIBOR and for which we pay a fixed rate of interest.
