Senior Secured Credit Agreement

On April 3, 2012, the Company entered into a new credit agreement (the "Credit Agreement"), which governs its new senior secured revolving credit facility (the "Credit Facility"), which provides for a $75.0 million senior secured revolving credit facility, with a $25.0 million sublimit for the issuance of letters of credit. As of March 31, 2013, no amounts were outstanding and $1.1 million in letters of credit had been issued under the Credit Facility, therefore the remaining availability under this facility was $73.9 million. All borrowings under the Credit Facility mature on April 3, 2017.

Borrowings under the Credit Facility bear interest, at the Company's option, at either (i) the Alternate Base Rate ("ABR") (the highest of the administrative agent's corporate base rate of interest, the federal funds rate plus 0.5%, or the one-month Eurodollar rate (as defined in the Credit Agreement) plus 1%), plus an applicable margin that ranges between 3.0% and 4.5%, depending on the Company's leverage ratio, or (ii) the Eurodollar rate plus an applicable margin that ranges between 4.0% and 5.5%, depending on the Company's leverage ratio. The Company will pay a per annum fee on all letters of credit issued under the Credit Facility, which fee will equal the applicable margin for loans accruing interest based on the Eurodollar rate, and the Company will pay a commitment fee of 0.75% per annum on the unused availability under the Credit Facility.

In addition, during any period of time that outstanding letters of credit under the Credit Facility exceed $10 million or there are any revolving borrowings outstanding under the Credit Facility, the Company will have to maintain compliance with a maximum secured leverage ratio (as defined in the Credit Agreement, being generally computed as the ratio of secured indebtedness to consolidated cash flow). The maximum secured leverage ratio is 3.50 to 1.00.

The Company's obligations under the Credit Agreement are guaranteed by substantially all of the Company's current domestic subsidiaries (collectively, the "Guarantors"), and the obligations of the Company and the Guarantors are secured by liens on substantially all of the vessels owned by the Company and the Guarantors, together with certain accounts receivable, equity of subsidiaries, equipment and other assets.

7.125% Senior Secured Notes due 2017

The 7.125% Senior Secured Notes are guaranteed by each of the Guarantors that guarantee the Company's obligations under its Credit Agreement. The notes are secured by liens on all collateral that secures the Company's obligations under its Credit Agreement, subject to limited exceptions. The liens securing the notes share on an equal and ratable first priority basis with liens securing the Company's Credit Agreement. Under the intercreditor agreement, the collateral agent for the lenders under the Company's Credit Agreement is generally entitled to sole control of all decisions and actions.

10.5% Senior Notes due 2017 (Formerly Secured prior to April 3, 2012)

The indenture governing the 10.5% Senior Notes provides that all the liens securing the notes may be released if the Company's total amount of secured indebtedness, other than the 10.5% Senior Notes, does not exceed the lesser of $375.0 million and 15.0% of the Company's consolidated tangible assets. The Company refers to such a release as a "collateral suspension." When a collateral suspension is in effect, the 10.5% Senior Notes due 2017 become unsecured. Following the closing of the 2012 debt issuances and the use of proceeds thereof to repay in full the prior secured credit facility, the liens securing the 10.5% Senior Notes were released on April 3, 2012 and a collateral suspension is currently in effect. The indenture governing the 10.5% Senior Notes also provides that if, after any such collateral suspension, the aggregate principal amount of the Company's total secured indebtedness, other than the 10.5% Senior Notes due 2017, were to exceed the greater of $375.0 million and 15.0% of the Company's consolidated tangible assets, as defined in such indenture, then the collateral obligations of the Company and guarantors thereunder will be reinstated and must be complied with within 30 days of such event.

The 10.5% Senior Notes are guaranteed by each of the Guarantors that guarantee the Company's obligations under its Credit Agreement.

10.25% Senior Notes due 2019

The 10.25% Senior Notes are guaranteed by each of the Guarantors that guarantee the Company's obligations under the Company's Credit Agreement.

3.375% Convertible Senior Notes due 2038

The Company may redeem the 3.375% Convertible Senior Notes at its option beginning June 6, 2013, and holders of the notes will have the right to require the Company to repurchase the notes on June 1, 2013 and certain dates thereafter or on the occurrence of a fundamental change.

The Company determined that upon maturity or redemption, it has the intent and ability to settle the principal amount of its 3.375% Convertible Senior Notes in cash, and any additional conversion consideration spread (the excess of conversion value over face value) in shares of the Company’s Common Stock.

Other Indenture Provisions

The Credit Agreement as well as the indentures governing the 7.125% Senior Secured Notes, 10.25% Senior Notes, 10.5% Senior Notes and 3.375% Convertible Senior Notes contain customary events of default. In addition, the Credit Agreement as well as the indentures governing the 7.125% Senior Secured Notes, 10.25% Senior Notes, 10.5% Senior Notes and 3.375% Convertible Senior Notes also contain a provision under which an event of default by the Company or by any restricted subsidiary on any other indebtedness exceeding $25.0 million would be considered an event of default under the Credit Agreement and indentures if such default: a) is caused by failure to pay the principal at final maturity, or b) results in the acceleration of such indebtedness prior to maturity.

The Credit Agreement as well as the indentures governing the 7.125% Senior Secured Notes, 10.25% Senior Notes and 10.5% Senior Notes contain covenants that, among other things, limit the Company's ability and the ability of its restricted subsidiaries to:


•	incur additional indebtedness or issue certain preferred stock;


•	pay dividends or make other distributions;


•	make other restricted payments or investments;


•	sell assets;


•	create liens;


•	enter into agreements that restrict dividends and other payments by restricted subsidiaries;


•	engage in transactions with affiliates; and


•	consolidate, merge or transfer all or substantially all of its assets.
