The Senior Unsecured Credit Facilities are syndicated with the following banks:

Borrowings under the Senior Unsecured Credit Facilities bear interest, at the Corporation's option, at rates based upon LIBOR or a base rate, plus, for each rate, a margin determined in accordance with a ratings-based pricing grid. The base rate is defined as the highest of (i) JPMorgan Chase Bank N.A.'s prime lending rate, (ii) the Federal Funds rate plus 0.5% and (iii) one-month LIBOR plus 1%.

The Revolving Facility expires on March 31, 2015, with any outstanding principal amounts, together with interest accrued thereon, due in full on that date. At June 30, 2011, the Corporation had borrowings of $60,000,000 outstanding under the Revolving Facility.

On March 31, 2011, the Corporation borrowed $250,000,000 under the Term Loan Facility, a portion of which was used to prepay the $111,750,000 Term Loan due 2012. The Corporation is required to make annual principal payments of $5,000,000, with the remaining outstanding principal, together with interest accrued thereon, due in full on March 31, 2015.

On March 31, 2011, the Corporation entered into the Second Amendment to Account Purchase Agreement with Wells Fargo Bank, N.A., which amended its $100,000,000 secured accounts receivable credit facility (the "AR Credit Facility"). As amended, purchases and settlements will be made monthly. Additionally, as amended, borrowings under the AR Credit Facility bear interest at a rate equal to theone-month LIBOR plus 1.35%. Borrowings under the AR Credit Facility are limited based on the balance of the Corporation's accounts receivable.

On April 1, 2011, the Corporation borrowed $100,000,000 under the AR Credit Facility, which in addition to proceeds from the Term Loan Facility, was used to repay $242,140,000 of 6.875% Notes that matured on that date. At June 30, 2011 and 2010, respectively, the Corporation had borrowings of $100,000,000 and $25,000,000 outstanding under the AR Credit Facility. The Corporation had no outstanding borrowings under the AR Credit Facility at December 31, 2010.

The Credit Agreement and the AR Credit Facility, as amended, require the Corporation's ratio of consolidated debt to consolidated earnings before interest, taxes, depreciation, depletion and amortization (EBITDA), as defined, for the trailing twelve month period (the "Ratio") to not exceed 3.5x as of the end of any fiscal quarter, provided that the Corporation may exclude from the Ratio debt incurred in connection with certain acquisitions for a period of 180 days so long as the Corporation maintains specified ratings on its long-term unsecured debt and the Ratio calculated without such exclusion does not exceed 3.75x. Additionally, if no amounts are outstanding under both the Revolving Facility and the AR Credit Facility, consolidated debt, including debt guaranteed by the Corporation, may be reduced by the Corporation's unrestricted cash and cash equivalents in excess of $50,000,000, such reduction not to exceed $200,000,000, for purposes of the covenant calculation.

Accumulated other comprehensive loss includes the unamortized value of terminated forward starting interest rate swap agreements. For the three and six months ended June 30, 2011, the Corporation recognized $239,000 and $474,000, respectively, as additional interest expense. For the three and six months ended June 30, 2010, the Corporation recognized $223,000 and $441,000, respectively, as additional interest expense. The ongoing amortization of the terminated value of the forward starting interest rate swap agreements will increase annual interest expense by approximately $1,000,000 until the maturity of the 6.6% Senior Notes in 2018.
