CREDIT AGREEMENT AND RELATED INSTRUMENTS

Credit Agreement

We are a party to a senior secured credit facility with Morgan Stanley Senior Funding, Inc. ("MSSF") consisting of a term loan facility and a $50.0 million revolving credit facility. As of March 31, 2013, we had $726.0 million in term loan borrowings and no borrowings under the revolving credit facility. We can also request the establishment of one or more swingline loans and/or revolving credit facilities with commitments in an aggregate amount not to exceed $200.0 million.

During the quarter ended March 31, 2013, we entered into Amendment No. 4 to our Credit Agreement dated as of November 2, 2010 with MSSF and the lenders referred to therein (as amended, the “Credit Agreement”). The amendment extended the term loan maturity date, provided new pricing terms and modified certain financial covenant provisions such that they are not scheduled to be reported unless we have revolving or swingline loan balances outstanding at the end of a fiscal quarter. We accounted for the fourth amendment as a debt modification with respect to amounts that remained in the syndicate and a debt extinguishment with respect to the $277.5 million that exited the syndicate and recorded debt extinguishment expense of $3.0 million. The amendment did not impact the net principal balance outstanding.

Under the Credit Agreement, we may borrow under a "Base Rate" or "Eurodollar Rate". The “Base Rate” is defined as a rate per annum equal to the greatest of (a) the prime rate, (b) 1/2 of 1% per annum above the federal funds effective rate, (c) the one-month Eurodollar Rate plus 1%, and (d) in the case of any term loans, 2.00%. The “Eurodollar Rate” is defined as (a) the rate per annum offered for deposits of dollars for the applicable interest period that appears on Reuters Screen LIBOR01 Page as of 11:00 A.M., London, England time, two business days prior to the first day of such interest period or (b) if no such offered rate exists, such rate will be the rate of interest per annum as determined by the administrative agent (rounded upwards, if necessary, to the nearest 1/100 of 1%) at which deposits of dollars in immediately available funds are offered at 11:00 A.M., London, England time, two business days prior to the first day in the applicable interest period by major financial institutions reasonably satisfactory to the administrative agent in the London interbank market for such interest period and for an amount equal or comparable to the principal amount of the loans to be borrowed, converted or continued as Eurodollar Rate loans on such date of determination. In the case of term loans, the Eurodollar Rate will not be lower than 1.00%.

The applicable interest rate margin per annum for each type of loan at March 31, 2013 is as follows:



	Base Rate	Eurodollar Rate
Revolving and swingline loans	3.50%	4.50%
Term loans	1.75%	2.75%

As of March 31, 2013, term loan borrowings were under the Eurodollar Rate and subject to an interest rate of 3.75%. The fair value of our term loan balance was $731.4 million based on a market quote provided to us by MSSF.

The amended term loan facility matures in February 2020 and principal amortizes at $7.3 million per year. During the six months ended March 31, 2013, we completed optional principal prepayments of $50.0 million. Subsequent to March 31, 2013, we completed an additional optional principal prepayment of $27.0 million. While there are currently no scheduled principal repayments until the maturity date, the Credit Agreement stipulates an annual payment of a percentage of Excess Cash Flow ("ECF"). The ECF percentage is between 0% and 50% depending on our consolidated leverage ratio as of the end of a fiscal year.

We currently pay an undrawn commitment fee of 0.375% on the unused portion of the revolving facility. If any letters of credit are issued, then we expect to pay a fronting fee equal to 0.25% per annum of the aggregate face amount of each letter of credit and a participation fee on all outstanding letters of credit at a per annum rate equal to the margin then in effect with respect to Eurodollar Rate-based loans on the face amount of such letter of credit.

The Credit Agreement includes financial covenants requiring a maximum leverage ratio and minimum fixed charge coverage ratio that are applicable only when revolving loans or swingline loans are outstanding at the end of a fiscal quarter and also contains other customary affirmative and negative covenants and events of default. We were in compliance with our covenants as of March 31, 2013.

Interest Rate Swap Agreements

In connection with the original Credit Agreement, in 2011, we entered into interest rate swap agreements for the purpose of minimizing the variability of cash flows in the interest rate payments of our variable rate borrowings. The cash flows received under the interest rate swap agreements are expected to offset the change in cash flows associated with LIBOR rate borrowings between the effective and maturity dates of the swaps. Our two outstanding swap agreements have notional amounts, fixed rates and expiration dates as follows: $121.0 million at 1.83% expiring January 2014 and $24.0 million at 2.21% expiring January 2015. We classify our interest rate swap balances as Level 2 fair value measurements. We determined the fair value of our interest rate swap agreements based on mid-market valuations reported to us by the counterparty to the swap agreements. Related to these interest rate swap agreements, we recorded a current liability of $0.8 million and a long-term liability of $0.5 million as of March 31, 2013 and a long-term liability of $1.9 million as of September 30, 2012. We reflect the change in fair value of the swaps through other income (expense), net and recorded income of $0.7 million in the first six months of 2013 and income of $0.2 million in the first six months of 2012.
