On June 29, 2012, the Company amended its revolving credit agreement to increase the borrowing capacity and adjust the interest rate spreads. On November 7, 2012, the Company further amended its revolving credit agreement to allow for the Company's issuance of the 5.625% Senior Unsecured Notes (discussed below), which resulted in certain adjustments to the existing covenants. The revolving credit agreement, as amended, permits the Company to borrow up to $475,000,000 at an interest rate equal to, at the Company's option, the base rate plus 0.50% to 1.25% or LIBOR plus 1.50% to 2.25%, or a combination thereof; provides for a fee of 0.20% to 0.40% of unused commitments; and contains certain covenants relating to the ratio of debt to operating performance measurements, interest coverage ratios and minimum net worth. Borrowings under the revolving credit agreement mature in June 2017 and are secured primarily by a pledge of the stock of our wholly-owned subsidiaries and our partnership and membership interests in the limited partnerships and limited liability companies. The Company was in compliance with the covenants contained in the revolving credit agreement at March 31, 2013.

On November 20, 2012, the Company completed a private offering of $250,000,000 aggregate principal amount of 5.625% senior unsecured notes due 2020 (the “Senior Unsecured Notes”). The net proceeds from the issuance of the Senior Unsecured Notes were used to reduce the outstanding indebtedness under the Company's existing revolving credit agreement, creating capacity to fund future acquisitions. The Senior Unsecured Notes are general unsecured obligations of the Company and are guaranteed by certain of its existing and subsequently acquired or organized wholly owned domestic subsidiaries, (the “Guarantors”). The Senior Unsecured Notes are pari passu in right of payment with all the existing and future senior debt of the Company and senior to all existing and future subordinated debt of the Company. Interest on the Senior Unsecured Notes accrues at the rate of 5.625% per annum and is payable semi-annually in arrears on May 30 and November 30, beginning on May 30, 2013, and ending on the maturity date of November 30, 2020.

Prior to November 30, 2015, the Company may redeem up to 35% of the aggregate principal amount of the Senior Unsecured Notes at a redemption price of 105.625% of the principal amount thereof, plus accrued and unpaid interest and liquidated damages, if any, using proceeds of one or more equity offerings. On or after November 30, 2015, the Company may redeem the Senior Unsecured Notes in whole or in part. The redemption price for such a redemption (expressed as percentages of principal amount) is set forth below, plus accrued and unpaid interest and liquidated damages, if any, if redeemed during the twelve-month period beginning on November 30 of the years indicated below:

Period		Redemption Price
2015		104.219%
2016		102.813%
2017		101.406%
2018 and thereafter		100.000%

The Senior Unsecured Notes contain certain covenants which, among other things, limit, but may not restrict the Company's ability to enter into or guarantee additional borrowings, sell preferred stock, pay dividends and repurchase stock. The Company was in compliance with the covenants contained in the indenture relating to the Senior Unsecured Notes at March 31, 2013.

In connection with the issuance of the Senior Unsecured Notes, the Company entered into a registration rights agreement, dated November 20, 2012 (the “Registration Rights Agreement”). Under the terms of the Registration Rights Agreement, the Company and the Guarantors agreed to use their commercially reasonable efforts to file an exchange offer registration statement with respect to the Senior Unsecured Notes with the Securities and Exchange Commission (the “SEC”) and consummate the exchange offer within 270 days from the date of the Registration Rights Agreement. On May 2, 2013, the registration statement became effective, following which, the holders of the Senior Unsecured Notes have 20 business days to complete their exchange.

The senior secured notes (the “Senior Secured Notes”) were issued on May 28, 2010, pursuant to a note purchase agreement, in the principal amount of $75,000,000 and are due May 28, 2020. The Senior Secured Notes, which were originally issued with a stated interest rate of 6.04%, were amended on November 7, 2012 to allow for the Company's issuance of the Senior Unsecured Notes, which resulted in an increase in the annual interest rate of 2% to 8.04%, and included certain other adjustments to the existing covenants. The Senior Secured Notes are pari passu with the indebtedness under the Company's revolving credit agreement and the Senior Unsecured Notes and require payment of principal beginning in August 2013. The note purchase agreement governing the Senior Secured Notes contains covenants similar to the covenants in the revolving credit agreement and includes a make whole provision in the event of any prepayment of principle. The Company was in compliance with the covenants contained in the note purchase agreement relating to the Senior Secured Notes at March 31, 2013.
