BACKGROUND WHEREAS: (A) by this Agreement, the Lender has established a credit facility (the "Credit Facility") in the amount of $153,091,000, pursuant to which the Lender shall, subject to the terms and conditions hereof, extend financing to the Shipowner (i) for the manufacture, construction, fabrication, financing and purchase by the Shipowner of the Vessel; (ii) for the payment of the related Construction Period Interest; and (iii) for the payment of the Guarantee Fees; (B) the establishment of the Credit Facility is in reliance upon the commitment of the United States to guarantee the payment of the unpaid interest on, and the unpaid balance of the principal of, the Floating Rate Note, including interest accruing between the date of an Indenture Default under the Floating Rate Note and the payment in full of the Guarantee; (C) a condition to the Lender's extension of the Credit Facility under this Agreement is the Lender's timely receipt of Certificates Authorizing Disbursement and issuance of the Guarantee of the Floating Rate Note; and (D) the Credit Facility may be utilized by the Shipowner in accordance with the terms and conditions of this Agreement. NOW, THEREFORE, in consideration of the premises and the mutual covenants herein contained, the parties hereto agree as follows: SECTION 1. DEFINITIONS AND PRINCIPLES OF CONSTRUCTION 1.01 Defined Terms. For the purposes of this Agreement, unless otherwise defined herein, defined terms shall have the meanings specified in Exhibit 1 hereto. 1.02 Principles of Construction. (a) The meanings set forth for defined terms in this Agreement shall be equally applicable to both the singular and plural forms of the terms defined. (b) Unless otherwise specified, all references in this Agreement to Annexes or Exhibits are to Annexes or Exhibits in or to this Agreement. 5 -2- (c) The headings of the Sections in this Agreement are included for convenience only and shall not in any way affect the meaning or construction of any provision of this Agreement. SECTION 2. THE CREDIT FACILITY 2.01 Amount. The Lender hereby establishes the Credit Facility, upon the terms and conditions set forth in this Agreement, in favor of the Shipowner in the maximum amount of $153,091,000 (the "Credit Facility Amount"), to enable the Shipowner to finance: (i) the manufacture, construction, fabrication, financing and purchase of the Vessel; (ii) Construction Period Interest; and (iii) the Guarantee Fees. The Lender will, subject to the terms and conditions provided herein, be obligated to fund under the Credit Facility the amount (the "Available Amount") which is equal to the excess, if any, of the Credit Facility Amount over the outstanding principal amount evidenced by the Floating Rate Note ("Outstanding Principal"). 2.02 Availability. Disbursements under the Credit Facility may be made once a calendar month and up to and including the Final Disbursement Date. "Final Disbursement Date" shall mean either October 31, 1998 or, if earlier, the date on which the Available Amount under the Credit Facility is cancelled in accordance with Section 9.01 or reduced to zero. 2.03 Disbursements and Minimum Amount of Utilizations. Upon satisfaction of Sections 3.01, 5.01 and 5.02, disbursements shall be made by advances from the Lender to the Shipowner ("Disbursements") in accordance with Section 3.01. Notwithstanding anything in this Agreement to the contrary, the Shipowner may not request a Disbursement under the Credit Facility for an amount (a) less than the smaller of (i) $1,000,000 or (ii) the Available Amount or (b) more than the Available Amount. 2.04 Floating Rate Note. Disbursements from the Credit Facility shall become the indebtedness of the Shipowner to the Lender under the Floating Rate Note. SECTION 3. DISBURSEMENT REQUIREMENTS 3.01 Disbursement Procedures. Upon receipt of each Certificate Authorizing Disbursement at least five Business Days prior to the proposed disbursement date, the Lender shall disburse funds in accordance with the terms of such Certificate Authorizing Disbursement to the Shipowner subject to the terms of this Agreement; provided that, if the Certificate Authorizing Disbursement and the request for disbursement referred to therein do not specify a disbursement date, then the disbursement date shall be the fifth Business Day (or such earlier or later Business Day as is requested by the Shipowner and is acceptable to the Lender) following the Lender's receipt of such Certificate Authorizing Disbursement. Promptly following each Disbursement, the Lender shall transmit to the Indenture Trustee a copy of the Certificate Authorizing Disbursement, a confirmation that the Disbursement was made, and a copy of Exhibit A to the Floating Rate Note, updated to reflect such Disbursement and other intervening, related events. SECTION 4. TERMS OF THE CREDIT 4.01 Principal Repayment. The Shipowner shall repay all Outstanding Principal in twenty-four (24) approximately equal, successive semi-annual installments, with each such installment to be payable on a Payment Date, provided that, on the last Payment Date, the Shipowner shall repay in full the remaining Outstanding Principal. 6 -3- 4.02 Interest Payment. (a) On each Interest Payment Date the Shipowner shall pay interest on the Outstanding Principal, calculated at an interest rate per annum equal to the Applicable Interest Rate therefor, as determined for each successive Interest Period. The interest rate on such amount shall be determined by the Indenture Trustee pursuant to the definition of Applicable Interest Rate. From time to time, the Lender will confirm LIBOR, Base Rate, and Applicable Interest Rate to the Indenture Trustee, provided, however, such confirmation shall not relieve the Indenture Trustee of its obligations under the Indenture to determine the Applicable Interest Rate. (b) The Shipowner shall pay to the Person entitled to any Unpaid Amount, on demand, interest on such Unpaid Amount (to the extent permitted by applicable law) for each Post Maturity Period at an interest rate per annum equal to the sum (the "Post Maturity Interest Rate") of (1) two percent (2%), plus (2) the Post Maturity Applicable Interest Rate. With respect to any Unpaid Amounts, the "Post Maturity Applicable Interest Rate" shall mean either (i) LIBOR on the Quotation Date therefor plus during the Construction Period, nine-twentieths of one percent (0.45%) per annum and thereafter, one-half of one percent (0.50%) per annum, or (ii) if, for any such Post Maturity Period, LIBOR cannot be determined, the rate per annum reasonably determined by the Person to whom such Unpaid Amount is owed before the last day of such Post Maturity Period to be that which expresses as a percentage rate per annum the cost which such Person would incur in funding such Unpaid Amount from whatever source it reasonably deems appropriate for such Post Maturity Period plus during the Construction Period, nine-twentieths of one percent (0.45%) per annum and thereafter, one-half of one percent (0.50%) per annum or (iii) if any such Unpaid Amount is an Accelerated Repayment, then during the first Post Maturity Period the rate which would have been applicable to such Unpaid Amount had it not so fallen due. In the absence of an Indenture Default, any interest which shall have accrued under this Section 4.02(b) in respect of an Unpaid Amount shall be due and payable and shall be paid by the Shipowner on demand on such dates as the Person to whom such Unpaid Amount is owed may specify by written notice to the Shipowner, or if there is an Indenture Default, any interest which shall have accrued under this Section 4.02(b) in respect of an Unpaid Amount shall be due and payable immediately and shall be paid by the Shipowner without demand and any payment by, or on behalf of, the Shipowner hereunder shall be governed by Section 7.02 and the provisions of the last paragraph of Section 9.03. As used herein, "Unpaid Amount" means all or any part of principal, accrued interest, fees or other amounts owing to the Lender under this Agreement or the Floating Rate Note which is not paid in full when and as due and payable, whether at Stated Maturity, by acceleration or otherwise, or any sum due and payable by the Shipowner to the Lender under any judgment of any court or arbitral tribunal in connection with this Agreement which is not paid on the date of such judgment; provided, however, that it is agreed that Unpaid Amount shall not include any part of the principal and interest on the Floating Rate Note, except that Unpaid Amount shall include all such amounts thereof as are not paid by the Shipowner as and when they are due but are paid by the Shipowner prior to payment thereof by the Secretary. "LIBOR" shall mean, in relation to any Post Maturity Period (other than the first Post Maturity Period contemplated by clause (iii) of Section 4.02(b)), the rate of interest per annum (rounded upward, if necessary, to the nearest 1/16 of 1%) last quoted by the principal London office of CITIBANK, N.A. prior to the close of business at such London office on the Quotation Date for the offering to leading banks in the London interbank market of U.S. Dollar deposits on an overnight basis and in an amount comparable to the Unpaid Amount to which LIBOR is to apply. "Accelerated Repayment" shall mean any part of the principal of the Floating Rate Note which became due and payable on a day other than its Payment Date. "Post Maturity Period" shall mean with respect to the period from the date an Unpaid Amount was due until such amount shall have been paid in full, each successive period, the first of which shall start on the date such Unpaid Amount was due (or the date of any such judgment or arbitral award, if earlier) and each other of which shall start on the last day of the preceding such period, and the duration of each of which shall be one day, or if LIBOR applies, then from and including the Quotation Date for such Post Maturity Period to but excluding the next Quotation Date or such other duration selected by the Person to whom such Unpaid Amount is due, provided, however, that in the case of any Accelerated Repayment, the first such Post Maturity Period applicable thereto shall be of a duration equal to the unexpired portion of its then applicable Interest Period. "Quotation Date" in relation to any Post Maturity Period means the day on which quotations would ordinarily be given by CITIBANK, N.A. in the London interbank market 7 -4- for dollar deposits for delivery on the first day of that period, provided, however, that if, for any such Post Maturity Period, quotations would ordinarily be given on more than one date, the Quotation Date for that period shall be the last of those dates. 4.03 Prepayment. (a) The Shipowner may from time to time prepay on any Interest Payment Date all or part of the Outstanding Principal evidenced by the Floating Rate Note, provided that: (i) any partial prepayment shall be in a minimum principal amount of $10,000,000, unless otherwise required by the Indenture; (ii) the Shipowner shall have given the Lender and the Indenture Trustee prior written notice of the prepayment (which shall be not less than 40 nor more than 60 days); (iii) the Shipowner shall have paid in full all amounts due under this Agreement as of the date of such prepayment, including, without limitation, interest which has accrued to the date of prepayment on the amount prepaid and all other amounts payable hereunder relating to the prepayment; and (iv) any amount prepaid hereunder shall not be considered part of the Available Amount. (b) Upon delivery to the Shipowner and the Secretary of the instrument satisfying and discharging the Indenture contemplated by Section 12.01 of the Exhibit 1 to the Indenture, all of the Shipowner's indebtedness, liabilities and obligations under this Agreement and the Fee Letter shall become immediately due and payable without demand upon, or notice to, the Shipowner. (c) Notwithstanding any other provision to the contrary herein, the Shipowner or the Secretary (after the Secretary's assumption of the Floating Rate Note pursuant to Section 6.09 of Exhibit 1 to the Indenture) may from time to time prepay all or part of the principal amount of the Floating Rate Note without any prepayment penalty or premium in accordance with Article III of Exhibit 1 to the Indenture. 4.04 Recapture. (a) The Shipowner shall pay to the Lender, upon the written request of the Lender, such amounts as shall be sufficient (in the reasonable judgment of the Lender) to compensate the Lender for any loss, expense or liability (including, without limitation, any loss, expense or liability incurred by reason of the liquidation or redeployment of deposits from third parties or in connection with obtaining funds to make or maintain any Disbursement) which the Lender reasonably determines is attributable to: (i) any failure to make scheduled payments on a Payment Date or any payment due in connection with any Redemption; or (ii) any failure by the Shipowner to borrow any advance for which a Certificate Authorizing Disbursement has been issued; or (iii) any revocation of a notice of prepayment given pursuant to Section 4.03(a); or (iv) any prepayment of the Floating Rate Note (including, without limitation, due to the issuance of any fixed rate notes) other than on an Interest Payment Date after giving five Business Days prior written notice to the Lender. (b) Without prejudice to any other provision hereof (and at the Shipowner's expense), the Lender shall use such reasonable efforts as it shall determine in its sole discretion to minimize any loss, expense or liability to the extent possible. 4.05 Evidence of Debt. The Shipowner agrees that to evidence further its obligation to repay all amounts disbursed under the Credit Facility, with interest accrued thereon, it shall issue and deliver to the Lender the Floating Rate Note. The Floating Rate Note shall (i) be in the form of Exhibit 2 to the Indenture; (ii) bear the Secretary's Guarantee, and (iii) be valid and enforceable as to its principal amount at any time only to the extent of the aggregate amounts then disbursed and outstanding thereunder, and, as to interest, only to the extent of the interest accrued thereon at the rate guaranteed by the Secretary; with any interest in excess thereof being evidenced by this Agreement. 8 -5- 4.06 Limit of United States Guarantee. None of the interest, fees, and expenses arising under Section 6 and none of the Indemnified Amounts, commissions, Taxes, Other Taxes, Post Maturity Interest Rate, interest in excess of 10.25% under the Floating Rate Note, the costs of obtaining any interest rate protection, or any other charges, costs, expenses, or indebtedness owed by the Shipowner under this Agreement to any Person is guaranteed by the United States.

(a) If, due to either (i) the introduction of or any change in or in the interpretation of any law or regulation or (ii) the compliance with any guideline or request from any central bank or other governmental authority (whether or not having the force of law), there shall be any increase in the cost to the Lender of agreeing to make or making, funding or maintaining the Disbursements or the Credit Facility, then the Shipowner shall from time to time, upon demand by the Lender, pay to the Lender additional amounts sufficient to compensate the Lender for such increased cost. (b) If the Lender determines that compliance with any law or regulation or any guideline or request from any central bank or other governmental authority (whether or not having the force of law) affects or would affect the amount of capital required to be maintained by the Lender or any corporation controlling the Lender and that the amount of such capital is increased by or based upon the existence of the Lender's commitment to lend hereunder and other commitments of this type, then, upon demand by the Lender, the Shipowner shall immediately pay to the Lender, from time to time as specified by the Lender, additional amounts sufficient to compensate the Lender or such corporation in the light of such circumstances, to the extent that the Lender reasonably determines such increase in capital to be allocable to the existence of the Lender's commitment to lend hereunder. (c) The Lender shall take such reasonable steps as it shall determine to minimize amounts demanded under this Section 6.04. In the event that the Lender transfers the booking office of the Credit Facility or the Floating Rate Note to minimize amounts demanded under this Section 6.04, any costs and expenses incurred in such transfer shall be paid by the Shipowner. (d) Each demand for payment by the Lender under this Section 6.04 shall be accompanied by a certificate showing in reasonable detail the basis for the calculation of the amounts demanded, which certificate, in the absence of manifest error, shall be conclusive and binding for all purposes. (e) The Lender shall notify the Shipowner of any event occurring after the date of this Agreement which entitles the Lender to compensation pursuant to this Section 6.04, as promptly as practicable, and in any event within ninety (90) days after it has knowledge of such event and has determined that a request for compensation hereunder shall be made.

The Shipowner shall, at the request of the Lender, execute and deliver to the Lender or to any party that the Lender may designate, any such further instruments as may be necessary or desirable to give full force and effect to a Disposition of Indebtedness by the Lender. 11.04 Disclaimer. The Lender shall not be responsible in any way for the performance of the Construction Contract or any other Shipowner Document, and no claim against the Shipbuilder or any other Person with respect to the performance of the Construction Contract will affect the obligations of the Shipowner under this Agreement or the Floating Rate Note. 11.05 No Waiver; Remedies Cumulative. No failure or delay on the part of the Lender in exercising any right, power or privilege under this Agreement, the Floating Rate Note or the Indenture and no course of dealing between or among the Shipowner and the Lender shall operate as a waiver of the rights of the Shipowner and the Lender against each other under this Agreement; nor shall any single or partial exercise of any right, power or privilege hereunder or under the Floating Rate Note or the Indenture preclude the Shipowner and the Lender from exercising against each other any other right, power or privilege hereunder. The rights and remedies expressly provided herein are cumulative and not exclusive of any rights or remedies which the Lender would otherwise have. No notice to or demand on the Shipowner in any case shall entitle the Shipowner to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the Lender under this Agreement to any other or further action in any circumstances without notice or demand. Notwithstanding any other provision to the contrary herein, no provision in this Agreement or any other related agreement preserves any rights in favor of the parties against the Secretary in the event that either party fails or delays to exercise any rights, powers, or privileges under this Agreement, the Floating Rate Note or the Indenture or engages in any particular course of dealing. 11.06 Currency. All payments of principal, interest, fees or other amounts due hereunder and under the Floating Rate Note shall be made in Dollars, regardless of any law, rule, regulation or statute, whether now or hereafter in existence or in effect in any jurisdiction, which affects or purports to affect such obligations. 11.07 Severability.

This Agreement may not be changed, discharged or terminated without the written consent of the parties hereto, and no provision hereof may be waived without the written consent of the party to be bound thereby. There may be no change, discharge, termination or claim of waiver of the terms of this Agreement without the prior written consent of the Secretary, who is entitled to enforce his rights under this Agreement as an intended third party beneficiary to this Agreement. The parties hereto acknowledge, however, that nothing in this Agreement creates in either the Shipowner or the Lender any right whatsoever against the Secretary. 19 -16- 11.09 Indemnification. Without limiting any other rights that the Lender may have hereunder or under applicable law, the Shipowner hereby agrees to indemnify the Lender from and against any and all damages, losses, claims, liabilities and related costs and expenses, including reasonable attorneys' fees and disbursements (all the foregoing being collectively referred to as "Indemnified Amounts") awarded against or incurred by the Lender arising out of or as a result of this Agreement or the Floating Rate Note excluding, however, Indemnified Amounts to the extent resulting from gross negligence or willful misconduct on the part of the Lender. In the event of an Indenture Default, all amounts received by the Lender pursuant to such indemnification after an Indenture Default shall be held and paid in the manner required by Section 7.02. 11.10 Benefit of Agreement. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the respective successors and assigns of the parties hereto; provided, however, that the Shipowner may not assign any of its rights or obligations hereunder without the prior written consent of the Lender and, to the extent set forth in paragraph 11.03 hereof, the Secretary. 11.11 Waiver of Jury Trial.

This waiver shall apply to any subsequent amendments, renewals, supplements or modifications to this Agreement or any assignment. 11.12 Execution in Counterparts. This Agreement may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original and all of which when taken together shall constitute one and the same Agreement.

Notwithstanding the provisions of this Agreement, in any conflict between this Agreement and the provisions of the Shipowner Documents, the Shipowner Documents shall govern the agreement between the parties hereto, but only with respect to the subject matter thereof. Notwithstanding the previous sentence, any provision in the Indenture (or any other agreement the Shipowner has entered into with any other Person) purporting to release the Shipowner of any indebtedness, liability or obligation shall not apply to any indebtedness, liability or obligation of the Shipowner hereunder and no termination of the Indenture (or any other agreement the Shipowner has entered into with any other Person) shall affect the continued effectiveness of this Agreement, which shall continue in full force and effect until the Credit Facility has been terminated and all indebtedness, liabilities and obligations of the Shipowner have been fully discharged and satisfied, the Floating Rate Note have been paid, satisfied and discharged in full, and there has elapsed a year and a day from the last payment received from, or on behalf, of the Shipowner.
