The Shipowner will on the Closing Date, execute and deliver a Trust Indenture (the "Indenture"), between the Shipowner and CITIBANK, N.A., a national banking association, as Indenture Trustee (the "Indenture Trustee"), in connection with the Obligations to be issued in respect of the Vessel, in the aggregate amount, with the maturity and bearing interest at the rate specified in the Indenture. E. Under the Authorization Agreement (the "Authorization Agreement"), Contract MA-13258 to be entered into on the Closing Date between the Secretary and the Indenture Trustee, the 6 Indenture Trustee will be authorized to endorse and execute, by means of facsimile signature of the Secretary and the facsimile seal of the Department of Transportation, on each of the Obligations issued and to authenticate a guarantee by the Secretary of the payment in full of all the unpaid interest on, and the unpaid balance of the principal of, each Obligation, including interest accruing between the date of default under such Obligation and the date of payment by the Secretary (individually, a "Guarantee" and, collectively, the "Guarantees").

G. The Shipowner will as further security to the Secretary, execute and deliver on the Delivery Date, a First Preferred Ship Mortgage, Contract MA-13260, created under and pursuant to Chapter 313, Title 46 United States Code, to the Secretary, as Mortgagee, upon and attaching to the Vessel. H. In connection with the execution and delivery of the Security Agreement, the Shipyard will enter into a consent to the assignment of the Construction Contract (the "Consent of Shipyard"). I. In order to implement certain aspects of the transactions contemplated by the Security Agreement and the Indenture, the Secretary, the Shipowner and CITIBANK, N.A., a national banking association, (the "Depository") will enter into the Depository Agreement, Contract MA-13262 (the "Depository Agreement"). J. The Shipowner will as further security to the Secretary, enter into a Title XI Reserve Fund and Financial Agreement, Contract MA-13261, with the Secretary (the "Title XI Reserve Fund and Financial Agreement"). -2- 7 W I T N E S E T H: That under the provisions of Title XI of the Merchant Marine Act, 1936, as amended and in effect on the date hereof (said provisions, as so amended and in effect on the date hereof, being called "Title XI") and in consideration of (i) the covenants of the Shipowner contained herein, (ii) the payment by the Shipowner to the Secretary of the charges for this Guarantee Commitment pursuant to Section 1104(f) of Title XI, and (iii) other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Secretary hereby commits itself as herein provided. The following executed documents are annexed to each counterpart of this Guarantee Commitment: the Security Agreement, the Title XI Reserve Fund and Financial Agreement, and the Depository Agreement. Annexed to each counterpart of this Guarantee Commitment are forms of the Consent of Shipyard, the Credit Agreement, the Indenture, the Obligations, the Authorization Agreement, the Mortgage, and the Secretary's Note. As used herein, the "Closing Date" refers to the date for the execution and delivery of the Obligations as provided in the Credit Agreement annexed hereto, subject to the conditions contained in Article V hereof. The Consent of Shipyard, the Credit Agreement, the Indenture, the Obligations, the Authorization Agreement, and the Secretary's Note (except as otherwise required by the Secretary), shall be executed and delivered substantially in the respective forms annexed hereto, except that the blanks, if any, therein shall be filled in as contemplated therein and herein and, except further that the maturity dates and interest rates of the Obligations must be further approved by the Secretary. The Mortgage shall be executed and delivered substantially in the form annexed hereto on the Delivery Date. ARTICLE I Findings and Determinations of Secretary Pursuant to Section 1104(d) of Title XI, the Secretary has found that the property or project with respect to which the Obligations will be executed will be, in his opinion, economically sound. Pursuant to Sections 1101(f), 1101(g) and 1104(b)(2) of Title XI, the Secretary has determined that the Actual Cost of the Vessel is $175,042,902. The Actual Cost of the Vessel is comprised of the amounts determined by the Secretary set forth in -3- 8 Table A annexed hereto, and the Secretary has determined that the amounts set forth in said Table A are itemized as also set forth therein. The Secretary may, at the request of the Shipowner, make a redetermination of the Actual Cost of the Vessel to include, in addition to the items set forth or referred to in said Table A, any other items or any increase in the amounts of the items set forth or referred to therein. The aggregate principal amount of the Obligations will not exceed 87-1/2% of the Actual Cost of the Vessel, and the Shipowner may execute the Obligations in amounts less than 87-1/2% of the Actual Cost during the Construction Period, provided that on or prior to two years after the Delivery Date, the Shipowner shall have executed and delivered Obligations equal to 87-1/2% of Actual Cost, subject to the provisions of the preceding paragraph. Pursuant to Section 1104(b)(3) and 1104(b)(5) of Title XI, respectively, the Secretary has determined that the maturity date of the Obligations is satisfactory and that the interest rate to be borne by the Obligations (exclusive of the charges for the Guarantee Fee and service charges, if any) to be issued on the Closing Date is reasonable, taking into account the range of interest rates prevailing in the private market for similar loans and risks assumed by the Secretary. Pursuant to Section 1104(b)(4) of Title XI, the Secretary has determined that payments of principal required by the Obligations are satisfactory. ARTICLE II Commitment to Guarantee Obligations The United States, represented by the Secretary, HEREBY COMMITS ITSELF TO GUARANTEE (as provided in the Obligations) the payment of the unpaid interest on, and the unpaid balance of the principal of, the Obligations, including interest accruing between the date of default under the Obligations and the payment in full of the Guarantees, and, to effect this Guarantee Commitment, hereby commits itself to execute and deliver the Authorization Agreement, the Security Agreement, the Title XI Reserve Fund and Financial Agreement, and the Depository Agreement on the Closing Date and the Mortgage on the Delivery Date. -4- 9 ARTICLE III The Obligations The Obligations shall be as provided in the Indenture and in the form of the Obligations annexed as Exhibit 2 to the Indenture.
