CERTAIN PAYMENTS AND REDEMPTIONS

(a) Mandatory Repayments and Sinking Fund Redemptions. The Obligations of each maturity are subject to repayment or redemption, as applicable, at a Redemption Price equal to 100% of the principal amount thereof, together with interest accrued thereon to the applicable repayment or sinking fund Redemption Date, through the operation of a mandatory repayment or sinking fund providing for the semi-annual repayment or redemption (i) for the 2005 Notes, on February 24 and August 24 of each year, commencing February 24, 1996, of $1,212,000 principal amount of 2005 Notes (or such lesser principal amount of 2005 Notes as shall then be outstanding) and (ii) for the 2020 Bonds, on February 24 and August 24 of each year, commencing February 24, 2006, of $1,212,000 principal amount of 2020 Bonds (or such lesser principal amount of 2020 Bonds as shall be then outstanding), plus, in each case, interest accrued thereon to the Redemption Date.

Notwithstanding the foregoing provisions of this subsection (a), if the principal amount of Outstanding Obligations shall be reduced by reason of any prepayment or redemption pursuant to Section 3.04 of Exhibit 1 to this Indenture, the principal amount of Obligations of each maturity to be repaid or redeemed pursuant to this subsection (a) on each subsequent mandatory repayment or sinking fund Redemption Date for such maturity of Obligations shall be reduced by an amount equal to the principal amount of such maturity of Obligations retired by reason of such prepayment or redemption pursuant to Section 3.04 of Exhibit 1 hereto divided by the number of mandatory repayment or sinking fund Redemption Dates (including the Stated Maturity of such maturity of Obligations) scheduled to occur after the date of such prepayment or redemption pursuant to Section 3.04 of Exhibit 1 to this Indenture (subject to such increase as shall be necessary so that the total principal amount of each maturity of Obligations to be prepaid or redeemed on any such repayment or sinking fund Redemption Date shall be an integral multiple of $1,000); provided that, the entire unpaid principal amount of the Outstanding Obligations of each maturity shall be paid not later than the stated Maturity of such maturity. The Shipowner shall,

- 5 -

in accordance with Section 3.02(d) of Exhibit 1 hereto, promptly after each prepayment or redemption pursuant to said Section 3.04, furnish to the Secretary, the Indenture Trustee and each Holder of an Obligation a revised table of repayments or sinking fund payments reflecting the reductions made pursuant to this subsection (a) as a result of such prepayment or redemption.

(b) Credit Against Mandatory Repayments or Sinking Fund Redemptions. In lieu of making all or any part of any mandatory repayment or sinking fund redemption of Obligations of each maturity or of making any mandatory prepayment or redemption of Obligations pursuant to Section 3.04 of Exhibit 1 hereto, the Shipowner may, at its option, receive credit for Obligations of such maturity not previously so credited or applied to reduce the principal amount of Obligations of such maturity Outstanding, (i) prepaid or redeemed by the Shipowner pursuant to the optional prepayment or redemption provisions provided for in subsection (c) of this Article, (ii) redeemed by the Shipowner pursuant to the optional redemption provision provided for in subsection (d) of this Article, or (iii) purchased or acquired by the Shipowner (other than by prepayment or redemption) and delivered to the Indenture Trustee for cancellation pursuant to Section 2.13 of Exhibit 1 hereto.

SECTION 1.02. Officer’s Certificates and Opinions of Counsel. (a) Each Officer’s Certificate or Opinion of Counsel with respect to compliance with a covenant or condition provided for herein (or waiver thereof) shall include:

(1) A statement that the Person or Persons making such certificate or rendering such opinion has or have read such covenant or condition;

(2) A brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

(3) A statement that, in the opinion of such Person or Persons, he or they have made or caused to be made such examination or investigation as is necessary to enable him or them to express an informed opinion as to whether or not such covenant or condition has been complied with (or compliance therewith has been waived); and

(4) A statement as to whether or not, in the opinion of such Person or Persons, such condition or covenant has been complied with (or such compliance has been waived).

(b) An Opinion of Counsel may be based (insofar as it relates to factual matters, information with respect to which is in the possession of any Person) upon a certificate or opinion of or representations in writing signed by an officer or officers of such Person or by such Person, as the case may be, and may be based upon an Opinion of Counsel signed by another counsel.

An Opinion of Counsel may state that said opinion is subject to the execution and delivery of designated instruments if copies of such instruments in form approved by such counsel are delivered to the Indenture Trustee prior to or concurrently with the delivery of said opinion.

(c) A certificate or opinion of a Person or Persons other than counsel may be based, insofar as it relates to legal matters, upon an Opinion of Counsel, unless the Person or Persons signing such certificate or opinion knew that such Opinion of Counsel was erroneous or, in the exercise of reasonable care, should have known that the same was erroneous.

(e) If the signer of any document is required to be approved by the Indenture Trustee, the acceptance of such document by the Indenture Trustee shall be sufficient and conclusive evidence of such approval.

(f) The fact that the delivery of any document is a condition precedent to any action required or permitted hereby shall not preclude the withdrawal revocation, rescission, modification or amendment of such document at any time

prior to such action, and, in the event of any such withdrawal, revocation or rescission, such document shall be disregarded for all purposes of this Indenture.

ARTICLE II

THE OBLIGATIONS

SECTION 2.01. Designation of Obligations. The Obligations of each series shall be designated as stated in the Special Provisions hereof or in the Supplemental Indenture establishing such series.

(c) If the Maturity of any Obligation or an Interest Payment Date for any Obligation shall be a day other than a Business Day, then such payment may be made on the next succeeding Business Day, with the same force and effect as if made on the nominal date for such payment, and no interest shall accrue thereon for the period after said nominal date (whether or not such next succeeding Business Day occurs in a succeeding month).

SECTION 2.03. Issuance of Obligations of Initial Series. At any time and from time to time after the execution and delivery of this Indenture, the Shipowner may deliver to the Indenture Trustee Obligations of the initial series issuable under this Indenture duly executed by the Shipowner as hereinafter provided, accompanied by a Request of the Shipowner, and thereupon the Indenture Trustee shall authenticate such Obligations, after endorsing thereon and authenticating the Guarantees of the United States in accordance with the Authorization Agreement, and shall deliver such Obligations and Guarantees in accordance with such Request. Each such Request shall specify the principal amounts, interest rates and Stated Maturities of the Obligations to be authenticated and the names and addresses of the Persons in whose name the Obligations are to be registered.

SECTION 2.04. Additional Obligations; Obligations of Additional Series. At any time or from time to time, the Shipowner may, with the approval of the Secretary, issue additional Obligations of any series and Stated Maturity theretofore issued or of one or more additional series, which shall (i) be in such principal amount, and (in the case of Obligations of any additional series) mature on such dates, bear interest at such rate or rates, be in such form or forms and have such other terms and provisions, as shall be set forth in a Supplemental Indenture providing for the issue thereof and (ii) be guaranteed by the United States under Title XI of the Act pursuant to a supplement to the Authorization Agreement.

If any officer of the Shipowner whose signature (facsimile or otherwise) appears on any Obligation shall cease to be such officer before such Obligation shall have been authenticated by the Indenture Trustee or delivered, such Obligation nevertheless may be authenticated, issued and delivered with the same force and effect as though the person or persons whose signature or signatures (facsimile or otherwise) appear on such Obligation had not ceased to be such officer or officers of the Shipowner.

SECTION 2.08. Authentication of Obligations and Guarantees. No Obligation or the Guarantee of the United States thereon shall be valid unless such Obligation shall bear thereon an authentication certificate, manually executed by the Indenture Trustee in accordance with the terms and conditions of the Authorization Agreement, substantially in the form or forms referred to in Section 2.02(b). Such authentication certificate, so executed, on any Obligation shall be conclusive evidence, and the only competent evidence, that such Obligation and such Guarantee have been duly executed, authenticated and delivered hereunder.

SECTION 2.09. Temporary Obligations. There may be issued from time to time in lieu of (or in exchange for) any definitive Obligation or Obligations one or more temporary Obligations of like series and Stated Maturity, with a Guarantee of the United States endorsed thereon and authenticated by the Indenture Trustee, substantially of the same tenor as the definitive Obligations in lieu of (or in exchange for) which they are issued, with or without the specification of any Redemption Price or Prices. Such temporary Obligation or Obligations may be in such authorized denomination or denominations as shall be stated in a Request of the Shipowner delivered to the Indenture Trustee prior to the authentication thereof, which Request shall specify the aggregate principal amounts and the series and Stated Maturities of such temporary Obligations.

(b) Any Obligation may be transferred at the Corporate Trust Office, by surrender of such Obligation for cancellation, accompanied by an instrument of transfer in form satisfactory to the Shipowner and the Indenture Trustee, duly executed by the registered Obligee or his duly authorized attorney, and thereupon the Shipowner shall execute, and the Indenture Trustee shall authenticate and deliver in the name of the transferee or transferees, a new Obligation or Obligations, and the Guarantee or Guarantees of the United States thereon, in authorized denominations of like series, tenor, interest accrual date and Stated Maturity and for the same aggregate principal amount.

(c) The Shipowner shall not be required to register transfers or make exchanges of (1) Obligations for a period of 15 days immediately prior to (A) an Interest Payment Date or (B) any selection of Obligations to be redeemed, (2) Obligations after demand for payment of the Guarantees and prior to the payment thereof or rescission of such demand pursuant to Section 6.02(a), or (3) any Obligation which has been selected for redemption in whole or in part.

If any Obligation surrendered for transfer or exchange has been selected for redemption in whole or in part, there may be endorsed on any Obligation or Obligations issued therefor an appropriate notation of such fact.

(d) Any Obligation shall be exchangeable for a like principal amount of Obligations of the same series, tenor, interest accrual date and Stated Maturity but of different authorized denominations. Obligations to be exchanged shall be surrendered at the Corporate Trust Office, and the Shipowner shall execute, and the Indenture Trustee shall authenticate and deliver in exchange therefor, the Obligation or Obligations, and the Guarantee or Guarantees of the United States thereon, requested by the Obligee in accordance with this paragraph (d) .

(e) As a condition precedent to any transfer or exchange of Obligations, the Shipowner may (except upon an exchange of temporary for definitive Obligations) require the payment of a sum sufficient to reimburse it for any taxes or other governmental charges that may be imposed with respect thereto and a sum not exceeding $2.00 for each Obligation delivered upon any such transfer or exchange.

SECTION 2.11. Who Treated as Owners. The Shipowner, the Indenture Trustee, the Secretary, and any office or agency for the payment of principal of (and premium, if any) or interest on the Obligations may deem and treat the Person in whose name any Obligation is registered in the Obligation Register as the absolute owner of such Obligation for all purposes, and neither the Shipowner, the Indenture Trustee, the Secretary, nor any such office or agency shall be affected by any notice to the contrary, whether such Obligation shall be past due or not. All payments of or on account of principal (and premium, if any) or interest, or pursuant to the Guarantee endorsed on such Obligation, to such registered Obligee shall be valid and effectual to satisfy and discharge the liability of the Shipowner and the Secretary to the extent of the sum or sums so paid, except as otherwise provided in Section 6.08.

SECTION 2.12. Lost, Stolen, Destroyed or Mutilated Obligations. Upon receipt by the Shipowner and the Indenture Trustee of evidence satisfactory to them of the laws, theft, destruction or mutilation of any Outstanding Obligation and the ownership thereof, the Shipowner may execute, and upon request of the Shipowner, the Indenture Trustee shall, but subject to all limitations imposed by the Authorization Agreement and only to the extent authorized thereby, authenticate and deliver, a new Obligation, and the Guarantee of the United States thereon, of like series, tenor, interest accrual date, principal amount and Stated Maturity (which may bear such notation as may be required by the Indenture Trustee or by usage or by the rules of any stock exchange upon which the Obligations are then listed and which shall bear a serial number different from the serial number of the lost, stolen, destroyed or mutilated Obligation) in lieu of such lost, stolen, destroyed or mutilated Obligation and, similarly, upon receipt by the Shipowner and the Indenture Trustee of evidence satisfactory to them of the loss, theft, destruction or mutilation of any Obligation which has or is about to become due and payable, the Indenture Trustee may deem the applicant with respect thereto to be the owner of said Obligation for the purpose of receiving payment on account thereof of principal (and premium, if any) upon maturity or interest or the payment of the Guarantee thereof; provided that, as conditions precedent to the execution, authentication and delivery of any new Obligation in place of said Obligation or to any payment contemplated by this Section, (1) the Shipowner, the Indenture Trustee and the Secretary shall receive indemnity satisfactory to the Shipowner, the Indenture Trustee and the Secretary, (2) the Shipowner shall be reimbursed for all reasonable expenses (including any fees or expenses of the Indenture Trustee) incident thereto, and (3) said Obligation shall (unless the same shall have been lost, stolen or destroyed) be surrendered.

Obligations issued pursuant to this Section and the Guarantees endorsed thereon shall constitute original contractual obligations of the Shipowner and the United States, respectively, whether or not the lost, stolen or destroyed Obligations be at any time enforceable by anyone, and shall be equally and

proportionately entitled to the benefits of this Indenture with all other Outstanding Obligations issued hereunder.

The provisions of this Section 2.12 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of lost, stolen, destroyed or mutilated Obligations.

(b) The giving of a Secretary’s Notice to the Indenture Trustee.

The Indenture Trustee shall give to the Obligees, the Secretary and the Shipowner prompt notice in writing of any default in payment referred to in clause (a) of this Section 6.01 (unless such default shall have been remedied prior to the giving of such notice), and of the occurrence of any Indenture Default which shall be continuing; provided that, the Indenture Trustee shall have no duty to give any such notice unless and until a Responsible Officer of the Indenture Trustee, who is a Responsible Officer in its Corporate Trust

Office, has actual knowledge of such default or Indenture Default. Any such notice of an Indenture Default to the Obligees (i) shall specify the nature of such Indenture Default, (ii) shall state that, by reason thereof, the Indenture Trustee is entitled under the Indenture to demand payment by the Secretary of the Guarantees, (iii) shall set forth the provisions of Section 6.04(b)(3) and (5), and (iv) shall advise the Obligees of the provisions of Section 6.02.

The Indenture Trustee shall give to each Obligee and to the Shipowner prompt written notice of any demand made by the Indenture Trustee pursuant to this paragraph (a), any such notice to Obligees to be given as provided in Section 6.04(c).

(b) If the Indenture Trustee shall not have made the demand referred to in Section 6.02(a) on or before the 30th day following an Indenture Default which shall have occurred and be continuing and if the Holders of all Outstanding Obligations shall not have theretofore elected to terminate the Guarantees as provided in Section 6.04(a)(2), any Holder of an Outstanding Obligation, by an Act of Obligees delivered to the Secretary (with copies thereof to the Indenture Trustee and the Shipowner), may, in place of the Indenture Trustee and on behalf of all Holders of Outstanding Obligations, make such demand, subject to all the provisions of, and with the effect provided in, Section 6.02(a); provided that, the right of each Holder under this paragraph (b) shall be without prejudice to the rights and duties of the Indenture Trustee under Section 6.02(a).

SECTION 6.03. Appointment of Indenture Trustee and Holders of Outstanding Obligations as Attorneys-in-Fact. Each Holder of an Outstanding Obligation by the purchaser and acceptance of its Obligation, irrevocably appoints the Indenture Trustee and each other Holder of an Outstanding Obligation its agent and attorney-in-fact for the purpose of making the demand provided for in Section 6.02 and (in the case of the Indenture Trustee) of receiving and distributing any payment or payments by the Secretary made pursuant to any such demand; provided that, no action or failure to act by the Indenture Trustee shall affect the rights of any Holder of an Outstanding Obligation to take my action whatsoever permitted by law and not in violation of the terms of the Obligations or of the Indenture.

SECTION 6.04. Termination and Payment of the Guarantees. (a) Except as otherwise provided in Section 6.08, the Guarantee with respect to any Obligation shall terminate in case, and only in case, one or more of the following events shall occur:

(1) Such Obligation shall have been Retired or Paid;

(2) The Holders of all Outstanding Obligations shall have elected, by Act of Obligees delivered to the Secretary, to terminate the Guarantees;

(3) Such Guarantee shall have been paid in full in cash by the Secretary; or

(4) The Indenture Trustee and each Obligee shall have failed to demand payment of such Guarantee as provided herein or in such Guarantee or in the Act.

(1) The Indenture Trustee shall hold the entire amount thereof in trust for the sole purpose of providing for the payments specified in subparagraph (5) below;

(2) No Obligation or Obligations shall thereafter be issued;

(3) The Obligations (A) shall represent only the right to receive the payments from the Indenture Trustee specified in subparagraph (5) below and, in the event the Indenture Trustee makes payment to the Shipowner pursuant to Section 4.03, from the Shipowner, (B) shall otherwise no longer constitute or represent an obligation of the Shipowner, and (C) shall not be entitled to any other rights or benefits under this Indenture;

(4) The Indenture Trustee shall forthwith give written notice to the Shipowner and to each of the Obligees, stating that it has received payment of the Guarantees in full in cash from the Secretary and that the same is available for distribution to the Obligees in the manner specified in subparagraph (5) below (and the Indenture Trustee shall give like notice to the Holders of the Obligations at least annually thereafter for a period of 6 years or until all Obligations shall have been cancelled, whichever is earlier); and

(5) Upon the surrender for cancellation of any Obligation, the Indenture Trustee shall forthwith pay to the Holder of such Obligation in cash an amount (less the amount, if any, required to be withheld in respect of transfer or other taxes on payment to such Holder) equal to the unpaid principal amount of such Obligation and the unpaid interest accrued thereon to the date on which the Secretary shall have paid the Guarantees in full in cash to the Indenture Trustee; provided that, for the purposes of this subparagraph (5), the Indenture Trustee (A) may deem any Person as the owner of an Obligation in accordance with Section 2.11 and (B) shall not be required to make any payment in violation of applicable law.

(c) Each notice to Obligees required by this Section shall be given by the Indenture Trustee by first class mail, postage prepaid, to the address of each Obligee appearing upon the Obligation Register.

(d) If the Secretary shall not have paid the Guarantees in full in cash to the Indenture Trustee within 30 days after any demand therefor pursuant to Section 6.02 (whether or not because the Secretary makes either of the findings referred to in the proviso of Section 6.02(a)), the Indenture Trustee shall give prompt written notice of such nonpayment to each Obligee and the Shipowner. If the Indenture Trustee shall have received notice of either of such findings, such notice to each Obligee shall so state.

SECTION 6.05. Rights of Indenture Trustee after Indenture Default. During the continuance of any Indenture Default, the Indenture Trustee shall have the right to demand and to receive payment of the Guarantees and shall have, with the consent of the Secretary as to matters other than the enforcement of the Guarantees (unless all the Guarantees shall have terminated as provided herein):

(a) the right (in its name, as the trustee of an express trust, or as agent and attorney-in-fact for each Holder of the Obligations as a class) to take all action to enforce its rights and remedies (including the institution and prosecution of all judicial and other proceedings and the filings of proofs of claim and debt in connection therewith), and to enforce all existing rights of the Holders of the Obligations as a class; and

(b) all other rights and remedies granted to the Indenture Trustee by this Indenture, or the Authorization Agreement, or by law.

In addition, during the continuance of an Indenture Default and if all the Guarantees shall have terminated as provided herein, the Indenture Trustee shall have the right, by written notice to the Shipowner, to declare the entire unpaid principal amount of the Outstanding Obligations and all unpaid interest to be immediately due and payable.

SECTION 6.06. (a) Obligees’ Right to Direct Indenture Trustee after Indenture Default. During the continuance of any Indenture Default, the Holders of a majority in principal amount of the Outstanding Obligations shall have the right, by an Act of Obligees, to direct the Indenture Trustee:

(1) to exercise or to refrain from exercising any right or to enforce any remedy granted to it by this Indenture; and

(2) to direct the time, method and place of the exercise of any such right or the enforcement of any such remedy:

provided that, subject to Section 7.03, the Indenture Trustee shall have the right not to take any such action if it shall determine in good faith that the action would involve it in personal liability, would subject it to expenses against which it had not been offered adequate security and indemnity, or would be unjustly prejudicial to the Obligees not parties to such direction.

Anything in this Section 6.06(a) to the contrary notwithstanding, the Indenture Trustee shall be obligated to demand payment of the Guarantees as provided in Section 6.02(a) unless the Holders of all Outstanding Obligations shall have elected to terminate the Guarantees as provided in Section 6.04(a)(2), in which case the Indenture Trustee shall be obligated to refrain from making such demand.

(b) Limitations on Obligees’ Right to ▇▇▇. No Obligee shall have the right to institute any judicial or other proceedings under this Indenture unless:

(1) the Indenture Trustee shall have been directed to institute such proceeding by the Holders of at least 25% in aggregate principal amount of the Obligations then Outstanding;

(2) the Indenture Trustee shall have been offered adequate security and indemnity against the costs, expenses and liabilities to be incurred by compliance with such direction;

(3) the Indenture Trustee shall not have instituted such proceeding within 60 days after the receipt of both such direction and such offer of security and indemnity;

(4) no direction inconsistent with such request shall have been given to the Indenture Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Obligations; and

(5) the institution and prosecution of such proceeding would not result in an impairment of the rights of any other Obligee, it being understood and intended that no one or more Obligees shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Obligees or to obtain or to seek to obtain priority or preference over any other Obligees or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all the Obligees.

(c) Unconditional Right of Obligees to ▇▇▇ for Principal (and Premium, if any) and Interest. Nothing in paragraph (b) shall (i) affect the obligation of the Shipowner to pay the principal of (and premium, if any) and interest on the Obligations in accordance with their terms or affect the right of any Obligee to institute any judicial or other proceeding to enforce the payment of his Obligations or (ii) limit the right of any Obligee to demand payment of the Guarantees pursuant to Section 6.02(b) or to institute any judicial or other proceeding to enforce the payment of the Guarantee of any Obligation of which he is the Holder.

SECTION 6.07. Undertaking for Costs. In any proceeding for the enforcement of any right or remedy under this Indenture, or in any proceeding against the Indenture Trustee for any action taken or omitted by it as Indenture Trustee, the court may in its discretion require the filing by any party litigant of an undertaking to pay the cost of such proceeding and may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant, having due regard to the merits and good faith of the claims or defense made by such party litigant. The provisions of this Section 6.07 shall not apply to any proceeding instituted by the Indenture Trustee or any proceeding instituted by any Obligee for the payment of the principal of (and premium, if any) and interest on his Obligations.

SECTION 6.08. Rescission of Payments. Notwithstanding any other provision of this Indenture, or of the Obligations, in the event that any payment to or on behalf of an Obligee of the principal of or interest due under any Obligation, or any portion of any such payment, shall at any time be repaid by such Obligee in compliance with an order (whether or not final) of a court of competent jurisdiction pursuant to any provision of the Bankruptcy Code (Title 11 of the United States Code) or any Federal Law replacing or superseding such Code, or applicable state law, and regardless of whether there has been any previous Indenture Default and any payment pursuant thereto, or whether such Obligation shall theretofore have been acquired by the Shipowner or cancelled, or whether an instrument satisfying and discharging this Indenture shall have been executed and delivered, (1) such Obligation shall not be deemed to have been Retired or Paid and shall be deemed to be Outstanding, (2) the return of such payment in whole or in part (but not the mere possibility that any such payment or portion thereof may be so required to be returned, nor any prior demand, suit or proceeding for such return) in compliance with the order of such court shall constitute a default in payment of such Obligation within the meaning of Section 6.01(a), which default shall be deemed to have occurred on the date of such repayment and which default, if continued for 30 days, will constitute a Payment Default, (3) the Guarantee of such Obligation and (to the extent necessary to enforce such Obligation and Guarantee) this Indenture shall be in full force and effect, and (4) the Person required to return such payment or portion thereof shall be deemed for all purposes to be a Holder of such Obligation and entitled to enforce such Obligation and Guarantee to the extent of such repayment and, if there shall not be any Indenture Trustee hereunder then in

office, such Person shall also be entitled to exercise on his own behalf all the rights of the Indenture Trustee hereunder necessary for such enforcement; provided that, in the event the Guarantee of any Obligation shall have terminated for reasons set forth in paragraphs (2) or (4) of Section 6.04(a) of this Indenture prior to the aforesaid date of repayment the provisions of this Section shall not apply to such Obligation.

SECTION 6.09. Assumption of Obligations by Secretary. Notwithstanding anything contained herein, (i) in the event the Shipowner shall fail to make any payment of principal or interest due on the Obligations on an Interest Payment Date and such failure to pay shall continue for a period of 25 days or (ii) in the event of a default under a mortgage, loan agreement, or other security agreement between the Secretary, the Shipowner and any other parties, the Secretary shall have the right to and may, in his sole discretion, (a) by giving to the Indenture Trustee at any time pursuant to clause (ii) above or, if pursuant to clause (i) above, on or after the 25th day of said 25 day period of such default (but prior to the receipt by the Secretary of any demand for payment of the Guarantees pursuant to Section 6.02) a Secretary’s Supplemental Indenture in the form of Exhibit 4 attached hereto, which Exhibit is incorporated herein by reference, assume the rights and obligations of the Shipowner under this Indenture and all Outstanding Obligations as provided in said Secretary’s Supplemental Indenture; and (b) if applicable, make any payment of principal or interest which is due under the Obligations. By the execution of this Indenture by the Indenture Trustee and the Shipowner it is agreed hereunder that a Secretary’s Supplemental Indenture shall be effective and binding upon the Indenture Trustee and the Shipowner and their respective successors or assigns without further act or deed of either as of the date executed and given to the Indenture Trustee by the Secretary as contemplated by this Section, and each of them for itself, its successors and assigns hereby irrevocably appoints the Secretary its true and lawful attorney-in-fact to execute and deliver said Secretary’s Supplemental Indenture. Upon any such assumption by the Secretary, the Secretary shall succeed to and be substituted for and may exercise every right and power of the Shipowner under this Indenture and the Obligations with the same force and effect as if the Secretary has been named as the Shipowner herein and therein. Upon any such assumption by the Secretary, the Indenture Trustee, upon request of the Secretary, shall promptly notify the holders of the Outstanding Obligations of such assumption. The Secretary may exercise its rights under this Section 6.09 as often as it deems appropriate in its sole discretion.

(d) Except during the continuance of any Indenture Default (other than an Indenture Default referred to in the parenthetical expression set forth in paragraph (c) of this Section), the Indenture Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Indenture Trustee.

(h) In all cases where this Indenture does not make express provision as to the evidence on which the Indenture Trustee may act or refrain from acting, the Indenture Trustee shall be protected (subject to paragraph (c) of this Section) in acting or refraining from acting hereunder in reliance upon an Officer’s Certificate as to the existence or nonexistence of any fact.

(i) The Indenture Trustee may consult with counsel satisfactory to the Indenture Trustee (who may be counsel to the Shipowner), and an Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in accordance with such Opinion of Counsel.

(m) The Indenture Trustee, in its individual or any other capacity, may become the owner or pledgee of Obligations with the same rights it would have if it were not Indenture Trustee.

(o) No provision of this Indenture shall require the Indenture Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(b) No successor Indenture Trustee shall be appointed without the prior written consent of the Secretary and until such successor Indenture Trustee shall enter into an amendment to the Authorization Agreement as set forth in the first sentence of Section 4.04 thereof.

(c) If a successor Indenture Trustee is appointed, approved by the Secretary and accepts such appointment, and the Shipowner shall have knowledge thereof, the Shipowner shall give notice to the Obligees of such appointment in the manner provided in Section 6.04(c). The failure of the Shipowner to give such notice shall not affect the validity of any such appointment.

SECTION 7.07. Effect of Appointment of Successor Indenture Trustee. Upon appointment and acceptance as Indenture Trustee, each successor Indenture Trustee shall forthwith, without further act or deed, succeed to all the rights and duties of its predecessor in trust under this Indenture and the Authorization Agreement.

Upon the written request of the successor Indenture Trustee or the Shipowner and upon payment of all amounts due to such predecessor under this Indenture, such predecessor shall transfer, assign and confirm to the successor Indenture Trustee all its rights under this Indenture by executing and delivering from time to time to the successor Indenture Trustee such further instruments and by taking such other action as may reasonably be deemed by such successor Indenture Trustee or the Shipowner to be necessary or appropriate in connection therewith.

Obligations and Guarantees authenticated after any such merger, consolidation or sale may be authenticated by the successor Indenture Trustee

ARTICLE VIII

CONSOLIDATION, MERGER OR SALE BY SHIPOWNER

SECTION 8.01. Consolidation, Merger or Sale by Shipowner. Nothing in this Indenture shall prevent any lawful consolidation or merger of the Shipowner with or into any other Person, or any sale of a Vessel or Vessels to any other Person lawfully entitled to acquire and operate such Vessel or Vessels or any sale by the Shipowner of all or substantially all of its assets to any other Person; provided that, except where the Shipowner shall be the Person surviving a merger or consolidation, the Person formed by or surviving such consolidation or merger, or to which the sale of such Vessel or Vessels shall be made, shall, by Supplemental Indenture, expressly assume the payment of the principal of and interest (and premium, if any) on the Proportionate Part of the Outstanding Obligations relating to such Vessel, or Vessels in accordance with the terms of the Obligations and of the Indenture and shall expressly assume the performance of the agreements of the Shipowner in the Indenture; provided further, that to the extent said Proportionate Part of the Outstanding Obligations is not so assumed, the Shipowner shall redeem or cause to be redeemed the principal amount of the Proportionate Part of Outstanding Obligations as is required by the Secretary, such redemption to be in accordance with the terms of the Obligations and of the Indenture. When a Person so assumes this Indenture and such Proportionate Part of the Outstanding Obligations, the Supplemental Indenture shall discharge and release the Shipowner from any and all obligations thereunder relating to such Proportionate Part of the Outstanding Obligations. In the event of such an assumption by a Person to whom a Vessel or Vessels have been sold (a) such Person shall succeed to, and be substituted for, and may exercise every right and power of the original Shipowner with the same effect as if such successor Shipowner had been named as the Shipowner herein and (b) such Proportionate Part of the Outstanding Obligations shall be surrendered to the Indenture Trustee for appropriate notation or for the issuance of new Obligations in exchange for such Proportionate Part of the Outstanding Obligations in the name of the successor Shipowner, as required by the Secretary. The principal amount of the Proportionate Part of the Outstanding Obligations shall be determined by the Secretary.

SECTION 8.02. Sale of the Vessel or Vessels by the Secretary. Nothing contained in this Indenture shall prevent the sale of a Vessel or Vessels to any other Person or Persons by the Secretary, by a court of law or by the Shipowner following, in connection with or in lieu of a foreclosure or similar action. Following any such sale (1) the Person to whom such Vessel or Vessels have been sold may by Supplemental Indenture expressly assume the payment of and interest (and premium, if any) on the Proportionate Part of the Outstanding Obligations relating to such Vessel or Vessels in accordance with the terms of the Obligations and the Indenture and shall expressly assume the performance of the Shipowner in the Indenture; and (2) in the event such Person does not so assume, the Secretary shall redeem the Proportionate Part of the Outstanding Obligations relating to such Vessel or Vessels without premium pursuant to Section 3.06 hereof; provided that, the Secretary shall allow or permit the sale of a Vessel or Vessels to the original Shipowner or to any affiliate of the Shipowner only if (i) the Secretary has not redeemed such Obligations prior to such sale, and (ii) such purchaser assumes such Proportionate Part of the Outstanding Obligations as contemplated by the preceding clause (1). When a Person so assumes this Indenture and such Proportionate Part of the Outstanding Obligations, the Supplemental Indenture shall discharge and release the Secretary from any and all obligations thereunder in the Secretary’s capacity as Shipowner relating to such Proportionate Part of the Outstanding Obligations. In the event of such an

assumption by a Person to whom a Vessel or Vessels have been sold (a) such Person shall succeed to, and be substituted for, and may exercise every right and power of the original Shipowner with the same effect as if such successor Shipowner had been named as the Shipowner herein and (b) such Proportionate Part of the Outstanding Obligations shall be surrendered to the Indenture Trustee for appropriate notation or for the issuance of new Obligations in exchange for such Proportionate Part of the Outstanding Obligations in the name of the successor Shipowner, as required by the Secretary. Any such sale or the execution of a Supplemental Indenture by any successor Shipowner shall not discharge or in any manner affect the obligation of the United States to pay the Guarantees pursuant to the terms thereof. The principal amount of the Proportionate Part of the Outstanding Obligations shall be determined by the Secretary.

ARTICLE IX

ACTS OF OBLIGEES

SECTION 9.01. Acts of Obligees. (a) Any request, demand, authorization, direction, notice, consent, waiver or other action required or permitted by this Indenture to be given or taken by Obligees may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Obligees in person or by an agent or attorney duly appointed in writing. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Indenture Trustee and, where it is hereby expressly required, to the Shipowner and the Secretary. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act of Obligees” signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent or attorney shall be sufficient for any purpose of this Indenture and (subject to Section 7.03) conclusive in favor of the Indenture Trustee and the Shipowner, if made in the manner provided in paragraph (b) of this Section.

(b) The fact and date of the execution by any Person of any instrument or writing referred to in paragraph (a) of this Section may be proved by the affidavit of a witness of such execution or by the certificate or acknowledgment of any notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by an officer of a corporation or a member of a partnership, on behalf of such corporation or partnership, such affidavit or certificate shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Indenture Trustee (or, if such instrument or writing is addressed to the Secretary, the Secretary) deems sufficient.

(d) Any request, demand, authorization, direction, notice, consent, waiver or other action by the Holder of any Obligation shall bind every future Holder of the same Obligation and the Holder of every Obligation issued upon the transfer thereof or in exchange therefor or in lieu thereof in respect of anything done or suffered to be done by the Indenture Trustee, any Paying Agent or the Shipowner in reliance thereon, whether or not notation of such action is made upon such Obligation.

ARTICLE X

(3) to eliminate any right reserved to or conferred upon the Shipowner;

(4) to make such provisions for the purpose of curing any ambiguity or correcting or supplementing any provisions in this Indenture as the Shipowner or the Secretary may deem necessary or desirable, provided such provisions are not inconsistent with this Indenture and shall not adversely affect the interests of the Obligees;

(5) to provide for the issuance of additional Obligations of any series and Stated Maturity theretofore issued under this Indenture or to set forth the terms and provisions of any one or more additional series of Obligations in accordance with Section 2.04; or

Upon receipt of a Request of the Shipowner that the Indenture Trustee execute any Supplemental Indenture and upon receipt of any Act of Obligees required pursuant to Section 10.04 and the consent of the Secretary required pursuant to Section 10.05, the Indenture Trustee shall enter into such Supplemental Indenture; provided that, the Indenture Trustee shall not be obligated to enter into any Supplemental Indenture which the Indenture Trustee believes adversely affects the Indenture Trustee’s own rights, duties or immunities under this Indenture.

SECTION 10.03. Reference in Obligations to Supplemental Indentures. Obligations authenticated and delivered after the execution and delivery of any Supplemental Indenture may, with the consent and approval of the Shipowner and the Indenture Trustee, contain a text modified to conform to such Supplemental Indenture or have imprinted or stamped thereon a legend with respect to such Supplemental Indenture, but no such modification or legend shall be necessary to make such Supplemental Indenture effective.

SECTION 10.04. Waivers and Supplemental Indentures with Consent of Obligees. With the consent of the Holders of not less than 60% in principal amount of the Outstanding Obligations of each series affected thereby, by Act of Obligees delivered to the Shipowner and the Indenture Trustee, (x) compliance by the Shipowner with any of the terms of the Indenture may be waived or (y) the Shipowner and the Indenture Trustee may enter into any Supplemental Indenture for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders of the Obligations issued

under this Indenture; provided that, no such waiver or Supplemental Indenture shall:

(a) Without the consent of all Obligees affected thereby (1) change the Stated Maturity or reduce the principal of any Obligation, (2) extend the time of payment of, or reduce the rate of, interest thereon, (3) change the due date of or reduce the amount of any mandatory sinking fund payment, (4) reduce any premium payable upon the redemption of any Obligation, or (5) change the coin or currency in which any Obligation or the interest thereon is payable; or

It shall not be necessary for any Act of Obligees under this Section to approve the particular form of any proposed Supplemental Indenture, but it shall be sufficient if such Act shall approve the substance thereof. Promptly after the execution of any Supplemental Indenture pursuant to this Section, the Shipowner shall give notice thereof to the Obligees in the manner provided in Section 6.04(c). Any failure of the Shipowner to give such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such Supplemental Indenture.

SECTION 10.05. Consent of Secretary. Subject to the provisions of Section 11.01, no waiver pursuant to Section 10.04 shall be effective, and neither the Shipowner nor the Indenture Trustee shall enter into any Supplemental Indenture, without the prior written consent of the Secretary thereto, and any purported action or attempt to take such action forbidden to be taken by this Section shall be void and of no effect.

SECTION 10.06. Continued Validity of the Guarantees. Notwithstanding anything herein to the contrary, this Indenture, the Guarantees and the Authorization Agreement shall each remain in full force and effect notwithstanding the assumption by the Secretary of the Obligations pursuant to the Secretary’s Supplemental Indenture entered into pursuant to Section 6.09, and pursuant to Section 1103(e) of the Act, the validity of the Guarantee of any Obligation shall be unaffected, and such Guarantee and all responsibilities, requirements and consents relating to the Secretary under the terms and provisions of this Indenture shall remain in full force and effect notwithstanding any such assumption by the Secretary as aforesaid.
