Senior secured notes

On January 26, 2011, the Company issued its 8.375% Senior Secured Notes (the “Senior Notes”) due February 15, 2018, for an aggregate principal amount of $175.0 million in a private offering for resale to qualified institutional buyers pursuant to SEC Rule 144A. The Senior Notes are secured and bear interest at 8.375% per annum. Interest is payable in cash semiannually in arrears on February 15 and August 15, of each year, beginning on August 15, 2011. The Company received net proceeds of approximately $170.5 million after deducting $4.5 million of issuance costs (included in deposits and other assets in the accompanying June 30, 2011 balance sheet). The Company intends to use the net proceeds from the Senior Notes for general corporate purposes and/or repurchases of its common stock or its Convertible Notes, or a special dividend to its stockholders. In the three and six months ended June 30, 2011, the Company incurred approximately $3.8 million and $6.6 million, respectively, of interest expense related to the issuance of the Senior Notes.

The Senior Notes are fully guaranteed on a senior secured basis, jointly and severally, by each of the Company’s existing domestic and future material domestic subsidiaries, subject to certain exceptions and permitted liens. Under certain circumstances, the Company’s subsidiaries may be released from these guarantees without the consent of the holders of the Senior Notes. The Senior Notes and the guarantees are secured by (i) first priority liens on substantially all of the Company’s and its guarantors’ assets, (ii) all of the equity interests in any of its domestic subsidiaries and (iii) 65% of the equity interests of its first-tier foreign subsidiaries held by the Company and its guarantors. The Senior Notes and the guarantees represent the Company’s and the guarantors’ senior secured obligations and effectively rank equally and ratably with all of its and the guarantors’ existing and future first lien obligations, to the extent of the value of the collateral securing such indebtedness, subject to permitted liens; are structurally subordinated to any existing and future indebtedness and liabilities of non-guarantor subsidiaries and rank equally in right of payment with all of its and the guarantors’ existing and future senior indebtedness.

The Company may redeem the Senior Notes, in whole or in part, at any time prior to February 15, 2015 at a price equal to 100% of the principal amount plus a “make-whole” premium, plus accrued and unpaid interest, if any, to the date of redemption. The “make whole” premium means, with respect to a note at any date of redemption, the greater of (i) 1.0% of the then-outstanding principal amount of such note and (ii) the excess of (A) the present value at such date of redemption of (1) the redemption price of such note at February 15, 2015, plus (2) all remaining required interest payments due on such note through February15, 2015 (excluding accrued but unpaid interest to the date of redemption), computed using a discount rate equal to the Treasury Rate as of such date of redemption plus 50 basis points, over (B) the then-outstanding principal amount of such note. The Company may also redeem the Senior Notes, in whole or in part, at any time on or after February 15, 2015 at the applicable redemption prices specified under the indenture governing the Senior Notes plus accrued and unpaid interest, if any, to the date of redemption. The redemption prices (expressed as a percentage of the principal amount) are 104.118% during the 12-month period beginning on February 15, 2015, 102.094% during the 12-month period beginning on February 15, 2016 and 100.0% during the 12-month period beginning on February 15, 2017 and thereafter. In addition, the Company may redeem up to 35% of the Senior Notes before February 15, 2014 with the net cash proceeds from certain equity offerings at a redemption price of 108.375% of the principal amount plus accrued and unpaid interest. If the Company experiences specific kinds of changes of control, the Company must offer to repurchase all of the Senior Notes at a purchase price of 101.0% of their principal amount, plus accrued and unpaid interest, if any, to the repurchase date.

The Company must offer to purchase with the proceeds of certain sales of assets totaling $20.0 million or greater, Senior Notes at 100.0% of the principal value of the notes plus accrued and unpaid interest. In the event of default, as defined in the indenture, holders of not less than 25.0% in aggregate principal amount of the Senior Notes then outstanding may declare all unpaid principal and accrued interest on all Senior Notes to be due and immediately payable.

The indenture governing the Senior Notes, among other things, limits the Company’s ability and its guarantors’ ability to incur indebtedness; to pay dividends or make other distributions; to make certain investments and other restricted payments; to create liens; consolidate, merge, sell or otherwise dispose of all or substantially all of its assets; to incur restrictions on the ability of a subsidiary to pay dividends or make other payments; and to enter into certain transactions with its affiliates.

Convertible senior notes

In June 2007, the Company issued its Convertible Notes for an aggregate principal amount of $200.0 million in a private offering for resale to qualified institutional buyers pursuant to SEC Rule 144A. The Convertible Notes mature on June 15, 2027, are unsecured, and bear interest at 1.00% per annum. The Convertible Notes will rank equally with any future senior debt and senior to any future subordinated debt and will be effectively subordinated to all existing and future liabilities of the Company’s subsidiaries and to any secured debt the Company may issue, to the extent of the value of the collateral. Interest is payable in cash semiannually in arrears on June 15 and December 15, of each year, beginning on December 15, 2007. The Company received net proceeds from the issuance of the Convertible Notes of approximately $195.1 million, after deducting the original issue discount of 2.25% and issuance costs. The discount and other issuance costs are being amortized to interest expense using the effective interest method through June 15, 2014, which is the earliest put date.

The Convertible Notes are convertible into shares of the Company’s common stock at an initial conversion price of $49.18 per share, or 20.3355 shares for each $1,000 principal amount of Convertible Notes, subject to adjustment for certain events as set forth in the indenture. Depending upon the price of the Company’s common stock at the time of conversion, holders of the Convertible Notes will receive additional shares of the Company’s common stock. Upon conversion of the Convertible Notes, the Company will have the right to deliver shares of its common stock, cash or a combination of cash and shares of its common stock. The Convertible Notes are convertible (i) during any fiscal quarter after the fiscal quarter ending September 30, 2007, if the closing sale price of the Company’s common stock for 20 or more trading days in a period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter exceeds 130% of the conversion price in effect on the last trading day of the immediately preceding fiscal quarter, or (ii) specified corporate transactions occur, or (iii) the trading price of the Convertible Notes falls below a certain threshold, or (iv) if the Company calls the Convertible Notes for redemption, or (v) on or after April 15, 2027, until maturity. In addition, following specified corporate transactions, the Company will increase the conversion rate for holders who elect to convert notes in connection with such corporate transactions, provided that in no event may the shares issued upon conversion, as a result of adjustment or otherwise, result in the issuance of more than 35.5872 common shares per $1,000 principal amount. The Convertible Notes include an “Irrevocable Election of Settlement” whereby the Company may choose, in its sole discretion, and without the consent of the holders of the Convertible Notes, to waive its right to settle the conversion feature in either cash or stock or in any combination at its option. The Convertible Notes may be redeemed by the Company at any time after June 20, 2014 at a redemption price of 100% of the principal amount plus accrued interest. Holders of the Convertible Notes have the right to require the Company to repurchase for cash all or some of their notes on June 15, 2014, 2017 and 2022 and upon the occurrence of certain designated events at a redemption price of 100% of the principal amount plus accrued interest.

Under the terms of the Convertible Notes, the Company is required to use reasonable efforts to file and maintain a shelf registration statement with the SEC covering the resale of the Convertible Notes and the common stock issuable on conversion of the Convertible Notes. If the Company fails to meet these terms, the Company will be required to pay special interest on the Convertible Notes in the amount of 0.25% for the first 90 days after the occurrence of the failure to meet and 0.50% thereafter. In addition to the special interest, additional interest of 0.25% per annum will accrue in the event of default, as defined in the indenture. The Company filed a shelf registration statement registering the Convertible Notes and common stock issuable upon conversion of the Convertible Notes in July 2007.
