Convertible Debt

2013 Convertible Senior Notes

During February 2008, the Company offered and sold in a public offering pursuant to the shelf registration statement $55.0 million aggregate principal amount of 2.75% convertible senior notes due 2013 (the “2013 convertible senior notes”). Interest is payable semi-annually, in arrears, on each August 15 and February 15, beginning on August 15, 2008, to the holders of record at the close of business on the preceding August 1 and February 1, respectively. The 2013 convertible senior notes mature on February 15, 2013. Holders of the 2013 convertible senior notes may convert their notes into a number of shares of the Company's common stock determined as set forth in the indenture governing the notes at their option on any day to and including the business day prior to the maturity date. The 2013 convertible senior notes are initially convertible into 76.7448 shares of the Company's common stock per $1,000 principal amount of the notes (which is equivalent to a conversion price of approximately $13.03 per share), subject to adjustment upon the occurrence of certain events. Upon the occurrence of a fundamental change, holders of the 2013 convertible senior notes may require the Company to repurchase some or all of their notes for cash at a price equal to 100% of the principal amount of the notes being repurchased, plus accrued and unpaid interest, if any. In addition, if certain fundamental changes occur, the Company may be required in certain circumstances to increase the conversion rate for any 2013 convertible senior notes converted in connection with such fundamental changes by a specified number of shares of the Company's common stock. The 2013 convertible senior notes are the Company's general unsecured obligations and rank equal in right of payment to all of its existing and future senior indebtedness, and senior in right of payment to the Company's future subordinated debt. The Company's obligations under the 2013 convertible senior notes are not guaranteed by, and are effectively subordinated in right of payment to all existing and future obligations of its subsidiaries and are effectively subordinated in right of payment to its future secured indebtedness to the extent of the assets securing such debt.

In connection with the issuance of the 2013 convertible senior notes, the Company entered into a capped call transaction with a hedge counterparty. The capped call transaction is expected to reduce the potential dilution upon conversion of the 2013 convertible senior notes in the event that the market value per share of the Company's common stock, as measured under the terms of the capped call transaction, at the time of exercise is greater than the strike price of the capped call transaction of approximately $13.03. The strike price of the capped call transaction corresponds to the initial conversion price of the 2013 convertible senior notes and is subject to certain adjustments similar to those contained in the notes. The capped call transaction provides for net-share settlement in the event that the volume-weighted average price per share of the Company's common stock on the settlement date exceeds the strike price of approximately $13.03 per share. In such event, the hedge counterparty would deliver to the Company a number of shares equal to a formula determined by the quotient resulting from (a) the shares being settled times the difference between the volume-weighted average price on the settlement date and the strike price of approximately $13.03 per share, divided by (b) the volume-weighted average price on the settlement date. If the volume-weighted average price on the settlement date equals or exceeds the cap price of $23.085 per share, the difference in (a) would be $23.085 minus $13.03, or $10.055. If the market value per share of the Company's common stock exceeds the cap price of the capped call transaction of $23.085, as measured under the terms of the capped call transaction, the dilution mitigation under the capped call transaction will be limited, which means that there would be dilution to the extent that the then market value per share of the Company's common stock exceeds the cap price of the capped call transaction. Although the capped call transaction covers approximately 4.2 million shares, in order to facilitate an orderly settlement process, the shares are divided into tranches of approximately 211,000 shares each, settling on the twenty consecutive trading days prior to the date of maturity of the Company's convertible notes. Thus, on each settlement date, approximately 211,000 shares would be settled, assuming a volume-weighted average price on such settlement date of $23.085. Assuming a volume-weighted average price of $23.085, the hedge counterparty would deliver to the Company approximately 91,904 shares on each settlement date, calculated as follows: 211,000 x ($23.085 - $13.03)/$23.085 = 91,904.
