         This Indenture shall consist of two parts: the Special Provisions and

                           -------------------------

         (a) Redemption of Notes from Proceeds of Bonds. If any Notes have been
issued hereunder, on or before the Stated Maturity Date of such Notes, the
Shipowner may redeem any or all of such Notes by issuing on the Redemption Date
of such Notes, Bonds in a principal amount equal to the outstanding principal
amount of and interest accrued on the Notes to be so redeemed. All proceeds of

Trustee. Delivery to such Holder by the Shipowner of an amount sufficient to
repay Holder's Note in full shall constitute conclusive evidence of such
payment for all purposes under this Indenture.

         (b)      Mandatory Redemption of Obligations.

                  1. The Obligations are subject to repayment, upon the terms
         and conditions provided in the Indenture, through the operation of a
         mandatory repayment schedule providing for the repayment in
         consecutive semi-annual installments of a principal amount as
         indicated in each such Obligation, commencing on the date which is the
         earlier of (A) the 1st or 15th day of a month, whichever first occurs,
         on or after the date which is six (6) months after delivery of the
         Vessel and (B) February 15, 2004 (the "Initial Payment Date"), and
         semi-annually thereafter commencing with the date that is six months
         following the Initial Payment Date (each a "Payment Date"), to and
         including, for the Note, the Stated Maturity, and for the Bonds, the
         thirty-sixth Payment Date, at one hundred percent (100%) of the
         principal amount thereof plus interest accrued thereon to such date;
         provided, however, that notwithstanding the foregoing provisions of
         this paragraph, in case the principal amount of the Notes shall be
         reduced by reason of any prepayment or redemption described in
         paragraph (c) of this Article Third, the principal amount of the
         Obligations to be repaid through the operation of the mandatory
         repayment schedule on each subsequent scheduled mandatory redemption
         date shall be subject to reduction as provided in Section 3.02 of the
         General Provisions to this Indenture. In the event the Notes issued
         hereunder are being redeemed through the issuance of Bonds, (i) the
         first regularly scheduled principal installment under the Bonds shall
         be due on the first Payment Date which falls after the first date of
         issue of the Bonds (ii) the remaining principal payments shall be
         payable according to the schedule incorporated into the Bonds and
         (iii) the last Payment Date shall be the thirty-sixth Payment Date.

                  2. The Shipowner shall redeem the Notes at a price equal to
         one hundred percent (100%) of the principal amount thereof, together
         with interest accrued to the date of redemption (the "Mandatory Note
         Redemption Date") fifteen (15) Business Days after the date (i) the
         Long Term Benchmark Rate equals or exceeds eight and three tenths
         percent (8.30%) per annum; or (ii), if during the Construction Period,
         the Short Term Construction Period Benchmark Rate equals or exceeds
         thirteen percent (13.00%) per annum; (iii) if, after the Construction
         Period, the Short Term Post-Construction Period Benchmark Rate equals
         or exceeds ten and twenty-five one hundredths percent (10.25%) per
         annum (each a "Trigger Event"). On the Mandatory Note Redemption Date,
         the Shipowner may redeem the Notes using the proceeds of Bonds issued
         on such Mandatory Note Redemption Date in accordance with the
         provisions of paragraph (a) of Article Third hereof.

                  3. The Notes issued hereunder are also subject to mandatory
         redemption at a redemption price equal to one hundred percent (100%)
         of the principal amount thereof, together with interest accrued
         thereon to the date of redemption, on the Stated Maturity Date of such
         Notes.

         (c)      Optional Redemption of Obligations.

                  1. At its option, the Shipowner may redeem the Notes of any
         Series from time to time, in whole or in part, at a redemption price
         equal to one hundred percent (100%) of the principal amount thereof,
         together with interest thereon to such redemption date, and any
         Liquidation Fees and Breakage Fees in such amounts as set forth in a
         written notice by the Agent to the Secretary, the Shipowner and the
         Indenture Trustee. Any partial redemption of Notes pursuant to Section
         8.01 of Exhibit 1 to this Indenture shall be subject to payment of any
         Liquidation Fees or Breakage Fees.

<PAGE>
                  2. At its option, the Shipowner may redeem the Bonds of any
         Series, in whole or in part, on any Payment Date, at a redemption
         price equal to one hundred percent (100%) of the principal amount
         thereof, together with interest accrued thereon to such date, together
         with the Make Whole Premium specified in such Bonds. No Make Whole
         Premium shall be owed in connection with any mandatory redemptions of
         the Bonds, any redemptions of the Bonds at the option of the
         Secretary, or any other redemption of the Bonds pursuant to any
         provisions of the Indenture not set forth in this paragraph.

                  3. If the Shipowner shall elect to make any such optional
         redemption, the Shipowner shall, at least five (5) Business Days in
         the case of Notes, and fifteen (15) days in the case of the Bonds, but
         not more than sixty (60) days, prior to such Redemption Date, deliver
         to the Indenture Trustee a Request stating that the Shipowner intends
         to exercise its right as set forth in this paragraph (c) to make such
         optional redemption and specifying the principal amount of Obligations
         which the Shipowner intends to redeem on such Redemption Date.

                                 ARTICLE FOURTH
                      Additions, Deletions and Amendments
                                  to Exhibit 1
                                  ------------

                  (a) Concerning Section 3.08. The last sentence of Section
         3.08 is amended to read: "A copy of the notice shall be mailed by
         first class mail, postage prepaid, in the case of the Note, at least 3
         days, and, in the case of the Bonds, at least 30 days, prior to the
         Redemption Date to each Holder of any Outstanding Obligation that is
         to be redeemed, in whole or in part, at the last address appearing on
         the Obligation Register."

                  (b) Concerning Section 6.09. The following new section is
         added to Section 6.09 as subparagraph (c): "In the event that the
         Bonds are registered in the name of The Depository Trust Company
         ("DTC"), Cede & Co. ("Cede") or another nominee of DTC or Cede, and
         (i) if the Secretary assumes the Bonds pursuant to Section 6.09(a)
         hereof, or (ii) if the Secretary instructs the Shipowner and the
         Indenture Trustee to Terminate said registration, the Shipowner and
         the Indenture Trustee, promptly upon receipt of the notice of such
         assumption or upon receipt of notice of such termination, shall
         terminate or cause the termination of the Letter of Representations.
         The Indenture Trustee shall within 30 days from receipt of either such
         notice from the Secretary also instruct DTC to notify its direct and
         indirect participants of the need to reregister the Bonds in the names
         of the beneficial owners. Upon surrender by DTC of the Bonds issued in
         its name, the name of Cede or another nominee, the Shipowner shall
         issue at its sole expense, and the Indenture Trustee shall
         authenticate Bonds in the names provided to the Indenture Trustee by
         DTC."

                  (c) Concerning Registered and Beneficial Ownership of Bonds:
         Legends.

         (i) The Bonds shall be issued initially in the form of one or more
permanent global Bonds in definitive, fully registered form without interest
coupons (each, a "Global Bond"). Except as provided in paragraph (iii) below,
owners of beneficial interests in Global Bonds will not be entitled to receive
separate certificated bonds ("Definitive Bond") and will not be considered
holders thereof. Each such Global Bond shall be deposited with DTC or the
Indenture Trustee, as custodian for DTC, registered

                                       5
<PAGE>
in the name of DTC or a nominee of DTC, and duly executed by the Shipowner and
authenticated by the Indenture Trustee as provided in the Indenture. Each
Global Bond shall bear such legend as DTC may require.

         (ii) Members of, or participants in, DTC shall have no rights under
the Indenture with respect to any Global Bond held on their behalf by DTC or by
the Indenture Trustee as the custodian of DTC or under such Global Obligation,
and DTC may be treated by the Shipowner, the Indenture Trustee and any agent of
the Shipowner or the Indenture Trustee as the absolute owner of such Global
Bond for all purposes whatsoever. Notwithstanding the foregoing, nothing herein
shall prevent the Shipowner, the Indenture Trustee or any agent of the
Shipowner or the Indenture Trustee from giving effect to any written
certification, proxy or other authorization furnished by DTC or impair, as
between DTC and its members and participants, the operation of customary
practices of DTC governing the exercise of the rights of an owner of a
beneficial interest in any Global Bond.

         (iii) (1) The transfer and exchange of beneficial interests in Global
Bonds shall be effected through DTC, in accordance with the procedures of DTC
therefor. The transfer and exchange of Global Bonds shall be effected through
DTC or the Indenture Trustee, as the custodian for DTC, in accordance with the
Indenture and the procedures of DTC therefor.

               (2) A Global Bond shall be exchangeable for Definitive Bonds
registered in the names of persons owning beneficial interest in such Global
Bond only if any of the following events shall have occurred: (1) DTC notifies
the Shipowner that it is unwilling or unable to continue as depositary for such
Global Bond or DTC ceases to be a clearing agency registered under the
Securities Exchange Act of 1934, as amended, at a time when DTC is required to
be so registered in order to act as depositary, and a successor depositary is
not appointed by the Shipowner within 90 days thereafter, (2) the Shipowner
elects to terminate DTC's services or the book entry system, (3) the Secretary
assumes the Bonds or (4) the Secretary instructs the Shipowner and Indenture
Trustee to terminate the registration of the Global Bond.

               (3) Any Global Bond that is exchangeable for Definitive Bonds
registered in the name of the owners of beneficial interests therein pursuant
to this paragraph (iii) shall be surrendered by DTC to the Indenture Trustee to
be so exchanged, without charge, and the Shipowner shall execute and the
Indenture Trustee shall authenticate and deliver, upon such exchange of such
Global Bond, an equal aggregate principal amount of Definitive Bonds of
authorized denominations. Definitive Bonds issued in exchange for a beneficial
interest in a Global Bond pursuant hereto shall be registered in such names and
in such authorized denominations as DTC, pursuant to instructions from its
direct or indirect participants or otherwise, shall instruct the Indenture
Trustee in writing. The Indenture Trustee shall deliver such Definitive Bonds
to the Obligation Owners in whose names such Obligations are so registered in
accordance with instructions of DTC.

               (4) The registered Holder of a Global Bond may grant proxies and
otherwise authorize any beneficial owner, including DTC's members and
participants and beneficial owners that may hold interest through such members
and participants, to take any action which a Holder is entitled to take under
the Indenture or Bonds.

               (5) In the event of the occurrence of any of the events specified
in paragraph (iii)(2), the Shipowner will promptly make available to the
Indenture Trustee a reasonable supply of Definitive Bonds.

                                       6
<PAGE>
               (6) Notwithstanding any other provision of the Indenture, a
Global Bond may not be transferred except as a whole by DTC for such Global
Bond to a nominee of DTC or by a nominee of DTC to DTC or another nominee of
DTC.

         (iv.) At such time as all beneficial interests in a Global Bond have
either been exchanged for Definitive Obligations, redeemed, repurchased or
canceled, such Global Bond shall be canceled by the Indenture Trustee.

         (v.) The Indenture Trustee shall have no responsibility or obligation
to any owner of any beneficial interest in a Global Bond, a member of, or a
participant in DTC or any other beneficial owner with respect to the accuracy
of the records of DTC or its nominee or of any participant or member thereof,
with respect to any ownership interest in the Bonds or with respect to the
delivery to any participant, member, beneficial owner, or other Bond owner
(other than DTC) of any notice (including any notice of redemption) or the
payment of any amount or delivery of such Bonds (or other security or property)
under or with respect to such Bonds. All notices and communications to be given
to the Holders and all payment to be made to Holders in respect to the Bonds
shall be given or made only to or upon the order of the registered Holders
(which shall be DTC or its nominee in the case of a Global Bond). The rights of
owners of beneficial interests in any Global Bond shall be exercised only
through DTC, subject to the applicable rules and procedures of DTC. The
Indenture Trustee may rely and shall be fully protected in relying upon
information furnished by DTC with respect to its members, participants and any
beneficial owners.

                            AND OPINIONS OF COUNSEL

         SECTION 1.01. Definitions. For the purposes of this Indenture,
capitalized terms shall have the meanings specified in Schedule A to the
Indenture unless otherwise expressly provided.

         SECTION 1.02. Officer's Certificates and Opinions of Counsel. The
Responsible Officer of the Person executing an Officer's Certificate with
respect to a covenant or condition provided for in this Indenture shall certify
that the officer (a) has read such covenant or condition; (b) has made or
caused to be made such independent examination or investigation as is necessary
to enable him to express an informed opinion with respect to such covenant or
condition; and (c) believes to the best of his knowledge that such condition or
covenant has been met. A lawyer issuing an Opinion of Counsel shall include the
same representations, except that insofar as it relates to factual matters, if
it is in the lawyer's professional opinion that reliance upon a certificate or
an Opinion of Counsel is appropriate, the lawyer may so rely upon such
certificate or opinion. Each Officer's Certificate and Opinion of Counsel shall
set forth the pertinent supporting information and shall be subject to the
Secretary's review of its adequacy and accuracy.

                                   ARTICLE II
                                THE OBLIGATIONS

         SECTION 2.01. Issuance of Obligations of Initial Series. (a) 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,
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.

         (b) The initial series of Obligations shall set forth their respective
principal amounts (in the denominations provided in the Special Provisions),
interest rates per annum, and Stated Maturities, and shall be payable as to
principal and interest and premium, if any, in any legal coin or currency of
the United States and shall be subject to redemption as provided in Article
III.

         (c) The principal and interest and any premium due on the Obligations
shall be paid by (i) the Corporate Trust Office or (ii) a Paying Agent by (x)
certified or official bank check mailed by first class postage prepaid to the
addresses of the Obligees appearing on the Obligation Register or (y) at the
request of an Obligee, received by the Indenture Trustee at least three
Business Days prior to the date of payment, by wire transfer to a commercial
bank in the United States or by credit to an account maintained by the Obligee
with the Indenture Trustee without presentment of the Obligation. Prior to any
sale, assignment or transfer of such Obligation, the Holder is required to
present the Obligation to the Indenture Trustee so that a proper notation of
all principal payments under (y) are made on the Obligation.

                                       4
<PAGE>
         (d) The Indenture Trustee agrees that within 30 days from the date of
any payment of principal or interest when the same shall become due and payable
by reason of Maturity or redemption, a Responsible Officer in the Corporate
Trust Office of the Indenture Trustee shall ascertain to his satisfaction that
checks in payment of such amounts have been mailed to the addresses of the
Obligees as provided above, if payment is to be made by check, or if payment is
to be made by wire transfer, or by credit to an account maintained by the
Obligee with the Indenture Trustee, that such funds have been wired or
credited, or if payment is to be made at the Corporate Trust Office, that funds
were held by the Indenture Trustee for such payment on the date the payment was
due. The Indenture Trustee shall have no obligation to determine whether such
checks or payments were received by the Obligees.

         (e) 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.

         SECTION 2.02. Additional Obligations; Obligations of Additional
Series. At any 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 be for the purpose of
aiding in financing or refinancing the construction, reconstruction or
reconditioning of one or more of the Vessels and shall be (i) in such principal
amount, and 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)
guaranteed by the United States under the Act pursuant to a supplement to the
Authorization Agreement.

         SECTION 2.03. Legends on Obligations. Any Obligation may have
imprinted or stamped thereon any legend, consistent herewith, which is
prescribed by the Shipowner and approved by the Indenture Trustee, and approved
by the Secretary.

         SECTION 2.04. Dates of Obligations. Each Obligation of any series
shall be dated the date of its authentication by the Indenture Trustee.

         SECTION 2.05. Execution of Obligations. The Obligations shall from
time to time be executed on behalf of the Shipowner by a Responsible Officer
thereof (whose signature may be a facsimile), and its corporate seal (which may
be a facsimile), if any, shall be imprinted thereon and attested by its
secretary, assistant secretary or assistant trust officer (whose signature may
be a facsimile). If a Shipowner's officer, whose signature appears on any
Obligation, shall cease to be such an officer before such Obligation shall have
been authenticated by the Indenture Trustee, the Obligation nevertheless may be
delivered with the same force and effect as though the person had not ceased to
be a Shipowner's officer.

         SECTION 2.06. 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

                                       5
<PAGE>
authentication certificate, executed by the Indenture Trustee in accordance
with the terms and conditions of the Authorization Agreement. A duly executed
authentication certificate shall be conclusive evidence, and the only competent
evidence, that such Obligation and such Guarantee have been duly executed,
authenticated and delivered hereunder.

         SECTION 2.07. Registration, Transfer and Exchange. (a) The Indenture
Trustee shall keep an Obligation Register at the Corporate Trust Office for the
registration of ownership, transfers and exchanges of Obligations.

         (b) A registered Obligee may transfer an Obligation, 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 Obligee or its duly authorized
attorney, and thereupon the Shipowner shall execute, and the Indenture Trustee
shall authenticate and deliver in the name of the transferee, a new Obligation,
and the Guarantee 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 issued
therefor an appropriate notation of such fact.

         (d) Any Obligation may be exchanged 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.

         (e) As a condition precedent to any transfer or exchange of
Obligations, the Shipowner may 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 2.08. Who Treated as Owners. The Shipowner, the Indenture
Trustee, the Secretary, and any Paying Agent for the payment of principal of
(and premium, if any) or interest on the Obligations may deem 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 Paying Agent 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

                                       6
<PAGE>
principal (and premium, if any) or interest, or pursuant to the Guarantee, 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 2.09. Lost, Stolen, Destroyed or Mutilated Obligations. Upon
receipt by the Shipowner and the Indenture Trustee of evidence satisfactory to
them of the loss, theft, destruction or mutilation of any Outstanding
Obligation ("Lost Obligation"), the Shipowner may execute, and upon request of
the Shipowner, the Indenture Trustee shall authenticate and deliver, a new
replacement Obligation, with 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 and
which shall bear a serial number different from that of the Lost Obligation)
and in the event such Lost Obligation 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 any payments due
on account thereof; provided that (1) the Shipowner, the Indenture Trustee and
the Secretary shall receive an 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) a mutilated Obligation shall be surrendered.
Once the Indenture Trustee has issued a replacement Obligation, the Lost
Obligation shall not be enforceable. The provisions of this section are
exclusive and shall preclude (to the extent lawful) all other rights and
remedies with respect to the replacement or payment of Lost Obligations.

         SECTION 2.10. Reacquired Obligations; Cancellation and Disposition of
Obligations. In the event the Shipowner shall reacquire any Obligations
(whether by purchase or otherwise), such Obligations shall forthwith be
delivered to the Indenture Trustee for cancellation. Except as provided in
Section 3.10(b), all Obligations surrendered for the purpose of payment,
redemption, transfer, exchange, or substitution, or in discharge in whole or in
part of any sinking fund payment shall, if surrendered to the Shipowner or any
Paying Agent, be delivered to the Indenture Trustee and shall be cancelled by
it. No Obligation shall be authenticated in lieu of or in exchange for any
Obligation cancelled as provided in this Section, except as may be expressly
permitted by this Indenture. Obligations cancelled by the Indenture Trustee
shall be delivered or disposed of as directed by a Request of the Shipowner.

                                  ARTICLE III
                           REDEMPTION OF OBLIGATIONS

         SECTION 3.01. Redemptions Suspended During Default. Notwithstanding
the following provisions of this Article III, neither the Shipowner nor the
Indenture Trustee shall redeem any Obligations, except pursuant to Section 3.04
or 3.06, during the continuance of any Indenture Default, except that, where
the mailing of notice of redemption of any Obligations shall have theretofore
been made, the Indenture Trustee shall redeem or cause to be redeemed such
Obligations if it shall have received a sum sufficient for such redemption.
Except as aforesaid, any moneys received by the Indenture Trustee for the
redemption of Obligations which may not be applied to the

                                       7
<PAGE>
redemption thereof shall be held in trust by the Indenture Trustee and applied
in the following manner: (1) in case such Indenture Default or such event shall
no longer be continuing, such moneys shall thereafter be applied to the
redemption of Obligations in accordance with the applicable provisions of the
Obligations and of this Article III, (2) in the event the Secretary shall have
assumed the Obligations pursuant to Section 6.09 or shall have been required to
pay the Guarantees, such moneys shall be paid over by the Indenture Trustee to
the Secretary or (3) if no Obligation shall be Outstanding, and the Secretary
shall not have been required to pay the Guarantees, such moneys shall be paid
to the Shipowner.

         SECTION 3.02. Redemptions Without Premium. (a) Mandatory Sinking Fund
Redemptions. The Obligations are subject to redemption at a Redemption Price
equal to 100% of the principal amount thereof, together with interest accrued
thereon to the Redemption Date, through the operation of a mandatory sinking
fund providing for semi-annual redemption commencing and continuing on the
dates and in the principal amounts specified in the Obligations, plus interest
accrued thereon to the applicable sinking fund Redemption Date; provided,
however, that in the event of any special redemption pursuant to Sections 3.04
or 3.05 below, the principal amount of Obligations to be redeemed on each
subsequent mandatory sinking fund Redemption Date shall be reduced by an amount
equal to the principal amount of the Obligations retired by reason of such
special redemption divided by the number of mandatory sinking fund Redemption
Dates (including the Stated Maturity of the Obligations) scheduled thereafter.

          (b) Credit Against Mandatory Sinking Fund Redemptions. In lieu of
making all or any part of any such mandatory sinking fund redemption of the
Obligations, the Shipowner may, at its option, receive 100% credit for
Obligations that have been (1) redeemed by the Shipowner pursuant to the
optional redemption provision provided in subsection (c) below, or (2)
purchased or acquired by the Shipowner (other than by redemption) and delivered
to the Indenture Trustee for cancellation pursuant to Section 2.10 above. These
Obligations shall be credited by the Indenture Trustee only under the following
conditions: at least 40 days but not more than 60 days prior to the due date
for such mandatory sinking fund redemption, the Shipowner delivers a Request to
the Indenture Trustee, (i) specifying the principal amount of Obligations to be
credited, (ii) certifying that none of the Obligations have previously been
made the basis of any credit and that the Shipowner is not restricted by
contract from seeking the requested credit, and (iii) presenting the
uncancelled Obligations to be credited.

         (c) Optional Sinking Fund Redemptions. At its option, the Shipowner
may redeem on any mandatory sinking fund Redemption Date, at a redemption price
equal to 100% of the principal amount thereof, together with interest accrued
thereon to such date, an additional principal amount of Obligations up to the
principal amount of the Obligations required to be redeemed under subsection
(a) above on such date, and before any reduction pursuant to the proviso of
that subsection. The right to make any such optional sinking fund redemption
shall not be cumulative. If the Shipowner shall elect to make any such optional
sinking fund redemption, the Shipowner shall, at least 40 days but not more
than 60 days prior to such mandatory sinking fund Redemption Date, deliver to
the Indenture Trustee a Request stating that the Shipowner intends to exercise
its right as

                                       8
<PAGE>
set forth in this subsection to make such optional sinking fund redemption and
specifying the additional principal amount of Obligations which the Shipowner
intends to redeem on such mandatory sinking fund Redemption Date.

         (d) Mandatory Redemptions Without Premium. The Obligations of each
series shall be subject to redemption without premium when redemption is
required by the conditions specified in Sections 3.04, 3.05 and 3.06.

         (e) Adjustments of Redemption Payments. If there is an adjustment in
mandatory redemption payments as a result of redemptions under this section or
any other provision of the Indenture, the Shipowner shall recompute the
remaining mandatory redemption payments pursuant to such provisions and shall,
at least 60 days prior to the next Interest Payment Date, submit to the
Secretary for his review of such recomputation to ascertain compliance with the
provisions of this Indenture, a table of revised mandatory redemption payments
on the Obligations of such series reflecting the adjustments made pursuant to
such provisions as a result of such redemption. Upon advice by the Secretary
that he finds such recomputation to comply with such provisions, the Shipowner
shall submit said table to the Indenture Trustee and the Indenture Trustee
shall promptly submit a copy thereof to each Holder of an Obligation of such
series.

         SECTION 3.03. Optional Redemptions of Obligations at Premium. At its
option, the Shipowner may redeem the Obligations, in whole or in part, at any
time, at the redemption prices specified in the Obligations, together with the
interest accrued thereon; provided that, no such redemption shall be made prior
to the date specified in the Special Provisions, directly or indirectly with
the proceeds of, or in anticipation of, borrowing by or for the account of the
Shipowner if such borrowing has an effective interest cost (calculated in
accordance with generally accepted financial practice) of less than the rate of
interest borne by the Obligations. The Shipowner may redeem such Obligations on
a date at least 40 days but not more than 60 days from the Indenture Trustee's
receipt of the Request to make such an optional redemption and specifying the
Redemption Date and the principal amount of Obligations which the Shipowner
intends to redeem. If this Request proposes a redemption prior to the date
specified in the Special Provisions, the Shipowner shall include with the
Request an Officer's Certificate stating that the redemption complies with the
proviso relating to early redemptions.

         SECTION 3.04. Redemptions to Comply with Section 1104A(b)(2) of the
Act. The Shipowner and the Secretary may Request a Redemption Date, at least 40
days but not more than 60 days from the Indenture Trustee's receipt of the
Request, for the redemption of certain Obligations because the principal amount
of the Outstanding Obligations are in excess of the amount eligible for
guarantee by the United States under Section 1104A(b)(2) of the Act. Upon
receipt, the Indenture Trustee shall promptly give notice to the Holders of the
Redemption Date as provided in Section 3.08 and on that date shall redeem the
principal amount of Obligations specified in the instruction together with the
interest accrued thereon.

         SECTION 3.05. Redemption after Total Loss, Requisition of Title,
Seizure or Forfeiture

                                       9
<PAGE>
of a Vessel or Termination of Certain Contracts. The Shipowner and the
Secretary may Request a Redemption Date, at least 40 days but not more than 60
days from the Indenture Trustee's receipt of the Request, for the redemption of
certain Obligations because of (1) an actual, constructive, agreed or
compromised total loss of a Vessel, (2) requisition of title to, or seizure or
forfeiture of a Vessel or (3) termination of a primary Construction Contract.
Upon receipt, the Indenture Trustee shall promptly give notice to the Holders
of the Redemption Date as provided in Section 3.08 and on that date shall
redeem such principal amount of Obligations together with the interest accrued
thereon.

         SECTION 3.06. Redemption After Assumption by the Secretary. At any
time after the Secretary has assumed the Obligations under Section 6.09 of the
Indenture, the Secretary may Request a Redemption Date, at least 40 days but
not more than 60 days from the Indenture Trustee's receipt of the Request, for
the redemption of all or part of the Obligations. Upon receipt, the Indenture
Trustee shall promptly give notice to the Holders of the Redemption Date as
provided in Section 3.08 and on that date shall redeem such principal amount of
Obligations together with the interest accrued thereon.

         SECTION 3.07. Determination of Obligations to be Redeemed. If less
than all the Obligations are to be redeemed pursuant to Sections 3.03, 3.04 or
3.05, the Indenture Trustee shall select the particular Obligations to be
redeemed by multiplying the total principal amount to be redeemed by a
fraction, the numerator of which is the amount each Holder of an Outstanding
Obligation is owed and the denominator is the total principal amount of the
Outstanding Obligations, making adjustment so that the principal amount of any
Obligation to be redeemed shall be $1,000 or an integral multiple thereof.

         SECTION 3.08. Notices of Redemption. (a) In case of any redemption of
Obligations, whether mandatory or optional, the Indenture Trustee shall send a
notice of redemption indicating (1) the Redemption Date, (2) the Redemption
Price, (3) if only a part of such Obligations is to be redeemed, the numbers or
other identification of the Obligations and the principal amount thereof to be
redeemed, (4) the place of payment upon redemption and (5) that interest shall
cease to accrue after the Redemption Date if the Indenture Trustee or any
Paying Agent shall have in fact received the required moneys. A copy of the
notice shall be mailed by first class mail, postage prepaid, at least 30 days
prior to the Redemption Date, to each Holder of an Outstanding Obligation that
is to be redeemed in whole or in part, at the last address appearing upon the
Obligation Register.

         SECTION 3.09. Deposit of Redemption Moneys. Prior to the opening of
business on any Redemption Date, the Shipowner shall cause to be deposited with
the Indenture Trustee or with any Paying Agent an amount sufficient for such
redemption with irrevocable directions to it to so apply the same. Failure to
so deposit said amount with the Indenture Trustee or the Paying Agent shall
render any notice to redeem of no effect.

         SECTION 3.10. Payment of Redemption Price. (a) If notice of redemption
shall have been given as provided above, the Obligations or portions thereof
specified in such notice shall become

                                      10
<PAGE>
due and payable on the Redemption Date and at the place of payment and the
Redemption Price stated in such notice, and on and after said Redemption Date
(unless the Shipowner shall default in payment of the Redemption price or shall
decide to cancel the notice of optional redemption) interest on the Obligations
or portions thereof so called for redemption shall cease to accrue. Upon
presentation and surrender of such Obligations in accordance with such notice,
such Obligations or the specified portions thereof shall be paid and redeemed
at the applicable Redemption Price.

         (b) Upon presentation of any Obligation redeemed in part only, the
Shipowner shall execute and the Indenture Trustee shall authenticate and
deliver to the order of the Holder thereof, at the expense of the Shipowner, a
new Obligation or Obligations of like series and Stated Maturity, of authorized
denominations, having endorsed thereon a Guarantee executed by the Secretary,
in principal amount equal to the unredeemed portion of the Obligation so
presented, or, at the option of such Holder, there may be noted thereon by the
Indenture Trustee or, at its direction, by any Paying Agent the payment of the
portion of the principal amount of such Obligation so called for redemption.

                                   ARTICLE IV
                CASH HELD BY INDENTURE TRUSTEE OR PAYING AGENTS

         SECTION 4.01. Generally. (a) To the extent required by the
Obligations, cash received by the Indenture Trustee or a Paying Agent shall be
promptly paid to the Holders of the Outstanding Obligations and all other cash
shall be held by the Indenture Trustee or a Paying Agent as a special deposit
in trust for application in accordance with this Indenture.

         (b) Cash held by the Indenture Trustee or any Paying Agent (other than
the Shipowner) under this Indenture: (1) need not be segregated; (2) shall not
be invested; and (3) shall not bear interest except to the extent the Shipowner
and the Indenture Trustee or Paying Agent may agree.

         SECTION 4.02. Paying Agents. (a) A Paying Agent appointed in writing
by the Shipowner shall enter into a contract with the Indenture Trustee,
agreeing that the Paying Agent will:

                  (1) hold in trust all sums held by it for the payment of the
principal of (and premium, if any) or interest on Obligations for the benefit
of the Holders of such Obligations, and for the benefit of the Indenture
Trustee;

                  (2) forthwith give written notice to a Responsible Officer in
the Corporate Trust Office signed by a Responsible Officer of the Paying Agent
of (A) any payment by the Shipowner of the principal of (and premium, if any)
or interest on Obligations, specifying the amount paid, segregated as to
principal (premium, if any) and interest, and identifying each Obligation on
which any payment was made by number, date, series, Stated Maturity and the
name of the Obligee, and (B) any failure of the Shipowner to make any such
payment when the same shall be due and payable; and

                                      11
<PAGE>
                  (3) promptly, and in no event later than ten days after any
payment made by it hereunder, give written notice to a Responsible Officer in
the Corporate Trust Office of all payments of Obligations made by it, including
and identifying all endorsements of payment made on Obligations by it, signed
and containing the specified information as provided in subparagraph (2) above,
and deliver for cancellation to the Indenture Trustee all Obligations
surrendered to the Paying Agent.

         (b) The Shipowner may at any time cause to be paid to the Indenture
Trustee all sums held in trust by any Paying Agent pursuant to this Section,
such sums to be held by the Indenture Trustee upon the same trusts.

         SECTION 4.03. Unclaimed Amounts. Subject to applicable law, including
State escheat laws, any moneys received by the Indenture Trustee or a Paying
Agent, for the payment of Obligations or Guarantees and remaining unclaimed by
the Holders thereof for 6 years after the date of the Maturity of said
Obligations shall be paid to the Shipowner upon its delivery of a Request to
the Indenture Trustee, unless the Secretary has previously paid the Guarantees,
in which case it shall be paid only upon a request of the Secretary. In such
event, such Holders shall thereafter be entitled to look only to the Person
that received the unclaimed amounts for the payment thereof, and the Indenture
Trustee or such Paying Agent, as the case may be, shall thereupon be relieved
from all responsibility to such Holders. No such Request or payment shall be
construed to extend any statutory period of limitations which would have been
applicable in the absence of such Request or payment.

         SECTION 4.04. Application of Funds. If at any time the Indenture
Trustee shall hold funds under Section 4.03, the application, distribution or
payment of which is not governed by a Request of the Shipowner or the Secretary
delivered pursuant to any provision of the Indenture, the Indenture Trustee
shall give written notice, in the absence of an Indenture Default, thereof to

Secretary has paid the Guarantees. The Shipowner or the Secretary, as
applicable, shall promptly thereafter deliver to the Indenture Trustee a
Request.

         The Shipowner hereby represents and agrees, so long as Obligations are
Outstanding, as follows:

         SECTION 5.01. Authorization, Execution and Delivery of Indenture. The
Shipowner has duly authorized the execution and delivery of this Indenture.

         SECTION 5.02. Payment. The Shipowner will duly and punctually pay the

                                      12
<PAGE>
         SECTION 5.03. Offices or Agencies of Shipowner. The Shipowner shall at
all times maintain an office in the location within the United States specified
in Article Second of the Special Provisions where Obligations may be presented
for payment, registration of transfer and exchange, and where demands to or
upon the Shipowner with respect thereto may be served. The Corporate Trust
Office and a Paying Agent shall also be deemed offices for such purpose.

                                   ARTICLE VI
                        INDENTURE DEFAULTS AND REMEDIES

         SECTION 6.01. What Constitutes "Indenture Defaults." (a) Each of the
following events shall constitute an "Indenture Default": (1) Default in the
payment of the whole or any part of the principal or interest on any of the
Outstanding Obligations when the same shall become due and payable, whether by
reason of Maturity, redemption, acceleration or otherwise, or any default
referred to in Section 6.08, and continuation of any such default for a period
of 30 days (herein called a "Payment Default"); and (2) The giving of a
Secretary's Notice to the Indenture Trustee.

         (b) The Indenture Trustee shall give to the Obligees, the Secretary
and the Shipowner prompt notice in writing of any Indenture Default (unless
such default shall have been remedied prior to the giving of such notice);
provided that, the Indenture Trustee shall have no duty to give any such notice
until a Responsible Officer of the Corporate Trust Office, has actual knowledge
of such Indenture Default. The notice of an Indenture Default to the Obligees
shall (1) specify the nature of such Indenture Default, (2) state that, by
reason thereof, the Indenture Trustee is entitled under the Indenture to demand
payment by the Secretary of the Guarantees, (3) set forth the provisions of
Section 6.04(b)(3) and (5), and (4) advise the Obligees of the provisions of
Section 6.02.

         SECTION 6.02. Demand for Payment of Guarantees. (a) If an Indenture
Default shall have occurred and be continuing, the Indenture Trustee shall, no
later than 60 days from the date of such Indenture Default, demand payment by
the Secretary of the unpaid interest to the date of such payment on, and the
unpaid balance of the principal of, all Outstanding Obligations, whereupon the
entire unpaid principal amount of the Outstanding Obligations and all unpaid
interest thereon shall become due and payable no later than 30 days from the
date of such demand; provided that, in the case of a demand made as a result of
a Payment Default, if, prior to the expiration of 30 days from the date of such
demand and prior to any payment of the Guarantees by the Secretary, the
Secretary shall find, and give written notice to the Shipowner and the
Indenture Trustee to the effect that, there was no Payment Default or that such
Payment Default was remedied prior to such demand, such demand and the
Indenture Default shall be of no legal effect or consequence. In each such
case, the Guarantees shall remain in full force and effect. 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 13.01.

         (b) If the Indenture Trustee shall not have made the demand referred
to in paragraph (a) of this Section on or before the 30th day following an
Indenture Default which shall have occurred and

                                      13
<PAGE>
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 paragraph (a) of this Section.

         SECTION 6.03. Appointment of Indenture Trustee and Holders of
Outstanding Obligations as Attorneys-in-Fact. Each Holder of an Outstanding
Obligation by the purchase 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.

         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 only terminate in case of the occurrence of one or more of the
following events:

                  (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.
         (b) Subject to the provisions of Section 6.08, when the Secretary
shall pay the Guarantees in full in cash to the Indenture Trustee:

                  (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, (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

                                      14
<PAGE>
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.

         (c) 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 any of the findings
or takes the action 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 any of these findings or actions, such notice to each Obligee shall so
state.

         SECTION 6.05. Rights of Indenture Trustee After Indenture Default.
Unless the Guarantees have terminated as provided herein, the Indenture
Trustee's sole right shall be to demand and receive payment of the Guarantees
from the Secretary and to take all action, on behalf of itself and each Holder,
to enforce its rights against the Secretary under the Guarantees, including but
not limited to the institution and prosecution of all judicial and other
proceedings. If the Guarantees have terminated under Section 6.04(a)(4) without
payment by the Secretary, the Indenture Trustee shall have the right on behalf
of itself and each Holder to take all action to enforce its rights directly
against the Shipowner (but not the Secretary), including but not limited to the
institution and prosecution of all judicial and other proceedings.

         SECTION 6.06. 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 has not been offered adequate security and indemnity, or would
be unjustly prejudicial to the Obligees not parties to such direction; and
provided further that, notwithstanding any other provision of this Indenture to
the contrary, the Indenture Trustee shall be

                                      15
<PAGE>
obligated to demand payment of the Guarantees as provided in Section 6.02(a)
unless the Holders of all the Outstanding Obligations shall have directed him
not to make demand.

         (b) Nothing in paragraph (a) shall affect the right of any Obligee to
institute any judicial or other proceeding, if the Indenture Trustee declines
to do so, against the Secretary while the Guarantees are in effect or against
the Shipowner or the Indenture Trustee if the guarantees have terminated under
Section 6.04(a)(4); provided, however, that such action does not seek to obtain
priority or preference over any other Obligees or to enforce any right under
this Indenture, except for the equal and ratable benefit of all the Obligees.

         SECTION 6.07. Attorneys' Fees and 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 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 shall not apply to any proceeding
instituted by the Indenture Trustee or any proceeding instituted by any Obligee
against the Secretary or the Shipowner for the payment of the principal of (and
premium, if any) and interest on the 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 a final order of a court of competent
jurisdiction pursuant to any provision of the Bankruptcy 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 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
Section 6.04(a)(2) or (4) 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. (a)
Notwithstanding anything

hereof, and upon the occurrence of a default in the payment of any principal or
interest due under the Obligations which has continued for 25 days or more or
upon the Secretary's giving of a Secretary's notice under this Indenture, the
Secretary may, in its sole discretion, prior to receipt by the Secretary of
demand for payment of the Guarantees in accordance with this Indenture assume
the rights and obligations of the Shipowner under this Indenture and the
Obligations by (i) giving to the Shipowner and Indenture Trustee a signed
notice stating that it has assumed the Obligations and the Indenture and (ii)
making any payment of principal or interest which is due under the Obligations.

         (b) The Indenture Trustee and the Shipowner hereby agree that, upon
the Indenture Trustee's receipt of the notice and payments referred to in
paragraph (a)(i) and (ii) of this section, the Secretary's assumption shall, as
of the date of the Secretary's execution of the notice, be effective and
binding upon the Indenture Trustee and the Shipowner and their respective
successors or assigns without further act or deed. Upon an 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
Obligation with the same force and effect as if the Secretary has been named as
the Shipowner herein and therein. The Secretary may exercise its rights under
this section as often as it deems appropriate in its sole discretion.

from liability for its own negligent action, its own negligent failure to act,
or its own willful misconduct; provided that:

                  (1) Except during the continuance of an Indenture Default, in
the absence of bad faith on the part of the Indenture Trustee, the Indenture

correctness of the opinions expressed therein; and

                  (2) The Indenture Trustee shall not be liable with respect to

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 in acting or refraining from acting hereunder in reliance upon an
Officer's Certificate as to the existence or nonexistence of any fact.

         (i) Subject to paragraph (c) of this Section, the Indenture Trustee
may consult with counsel satisfactory to the Indenture Trustee, and an Opinion

of any action taken, suffered or omitted by it hereunder in good faith and in
accordance with such Opinion of Counsel.

                                      18

         (j) Whenever it is provided that the Indenture Trustee shall take any
action, including the giving of any notice or the making of any demand, or
refrain from taking any action upon the happening or continuation of a

condition or upon the Request of the Shipowner or of Obligees or upon receipt

         (k) Subject to paragraph (c) of this Section, the Indenture Trustee
shall not be under any obligation to exercise any of the trusts or powers

Trustee security or indemnity satisfactory to it against the costs, expenses
and liabilities to be incurred thereby.

         (l) 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.

         (m) Notwithstanding any other provision of this Indenture, the
Indenture Trustee shall not take any action contrary to the terms of the
Authorization Agreement, and any such purported action or any attempt to take
such action shall be void and of no effect.

         (n) 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.

         (o) Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Indenture Trustee shall be subject to the
provisions of this Section.

for, and hold it harmless against, any loss, liability or expense which it may
incur or suffer without negligence or bad faith in acting under this Indenture

the Secretary

         SECTION 7.06. Appointment of Successor Indenture Trustee. (a) If any
notice of resignation or of removal shall have been given pursuant to Section
7.05, then a successor Indenture Trustee may be appointed by the Shipowner;
provided that, if such successor Indenture Trustee is not so appointed (or has
not accepted such appointment) within 15 calendar days after the giving of any
such notice, such appointment may be made (1) by the Secretary or (2) by a
court of competent jurisdiction upon the application of the Secretary, the

been, the Holder of an Outstanding Obligation for at least 6 months.

         (b) No successor Indenture Trustee shall be appointed without the
prior written consent of the Secretary and until such successor Indenture

         (c) If a successor Indenture Trustee is appointed, approved by the
Secretary and accepts such appointment, the Shipowner shall give notice to the
Obligees of such appointment in the manner provided in Section 13.01. 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.

Indenture Trustee under this Indenture and shall transfer, assign and confirm

the event of any merger (including for the purposes of this Section, the
conversion of a state bank into a national banking association or vice versa)
or consolidation of the Indenture Trustee into any other Person or in the event
of the sale of all or substantially all the Indenture Trustee's corporate trust
business, the Person resulting from such merger or consolidation, or the
transferee in the case of any such sale, shall forthwith notify the Shipowner
and, subject to Section 7.02(a) and 7.06(b), shall be the Indenture Trustee

         SECTION 8.01. Consolidation or Merger of Shipowner or Sale of Vessel.
(a) 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 by the
Shipowner, the Secretary or a court of law to any other Person lawfully
entitled to acquire and operate such Vessel or any sale by the Shipowner, the
Secretary, or a court of law 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, either (1) the Person formed by or
surviving such consolidation or merger, or the Person to which the sale of such
Vessel shall be made, shall expressly assume, by Supplemental Indenture, the
payment of the principal of and interest (and premium, if any) on the
Proportionate Part of the Outstanding Obligations, as determined by the
Secretary, relating to such Vessel and expressly assume the Shipowner's duties
under the Indenture, or (2) to the extent that the Secretary determines that
the Outstanding Obligations and the duties under the Indenture are not so
assumed, the Shipowner shall redeem the principal amount of those unassumed
Obligations in accordance with the terms of the Obligations and of the
Indenture.

         (b) 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 has 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

                                      21
<PAGE>
(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.

expressly provided, an Act of Obligees shall become effective when it is
delivered to the Indenture Trustee and, where it is expressly required, to the
Shipowner and the Secretary. Proof of execution of any instrument appointing an
agent or attorney to execute an Act of Obligees made in the manner of
subsection (b) below shall be sufficient for any purpose of this Indenture.

         (b) The fact and date of the execution by any Person of any instrument
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, stating that the individual signing such instrument acknowledged

instrument, 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
is addressed to the Secretary, the Secretary) deems sufficient.

         (c) Any Act of Obligees taken by the Holder of any Obligation shall
bind every future Holder of any of the Obligations in respect of anything done
or suffered to be done by the Indenture Trustee, any Paying Agent or the

the following purposes:

                  (1) to add to the covenants of the Shipowner;

                  (2) to evidence, pursuant to Article VIII, the succession of
another corporation or entity to the Shipowner or any assumption of all or
part of the Obligations;

Request of the Shipowner that the Indenture Trustee execute any Supplemental
Indenture and upon receipt of any Act of Obligees required pursuant to Section

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

Supplemental Indenture, but no such modification or legend shall be necessary
to make such Supplemental Indenture effective.

any waiver provided herein or to modify any of the provisions of this Section.

         It shall not be necessary for any Act of Obligees under this Section

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

otherwise is provided herein, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event.

in reliance upon any such waiver.

benefit of the Shipowner, the Indenture Trustee, the Holders and (until the
obligations to the Secretary shall have terminated as provided in Article XI)
the Secretary.

         SECTION 13.04. Execution of Counterparts. This Indenture may be
executed in any number of counterparts. All such counterparts shall be deemed
to be original and shall together constitute but one and the same instrument.

         SECTION 13.05. Table of Contents; Titles and Headings. Any table of
contents, the titles of the Articles and the headings of the Sections are not a
part of this Indenture and shall not be deemed to affect the meaning or

         SECTION 13.07. Payments in U.S. Currency. This is an international

essence, and such currency shall be the currency of account in all events. The
respective payment obligations of the Shipowner and the Indenture Trustee
hereunder shall not be discharged by an amount paid in another currency,
whether pursuant to a judgment or otherwise, to the extent that the amount so
paid on prompt conversion of such currency under normal banking procedures does
not yield after deduction of any and all fees, taxes or any other charges
imposed on the payment, the amount of United States dollars then due. In the
event that any payment by the Shipowner or the Indenture Trustee, whether
pursuant to a judgment or otherwise, upon conversion and transfer, does not
result in the payment of such amount of United States dollars at the place such
amount is due, each shall be entitled to demand immediate payment of, and shall
have a separate cause of action against the other for, the additional amount
necessary to yield the amount then due. In the event either the Shipowner or
the Indenture Trustee, upon the conversion of such judgment into dollars, shall
receive (as a result of currency exchange rate fluctuations) an amount greater
than that to which it was entitled, the defaulting party shall be entitled to
immediate reimbursement of the excess amount.

         SECTION 13.08. Shipowners not Immune. The Shipowner represents and
warrants that it is subject to civil and commercial law with respect to its
obligations under this Agreement, that the making and performance of this
Agreement constitutes private and commercial acts rather than governmental or
public acts and that neither the Shipowner nor any of its properties or
revenues has any right of immunity on the grounds of Sovereignty or otherwise
from suit, court jurisdiction, attachment prior to judgment, attachment in aid
of execution of a judgment, set-off, execution of a judgment or from any other
legal process with respect to its obligations under this Agreement. To the
extent that the Shipowner may hereafter be entitled, in any jurisdiction in
which judicial proceedings may at any time be commenced with respect to this
Agreement to claim for itself or its revenues or assets any such immunity, and
to the extent that in any such jurisdiction there may be attributed to the
Shipowner such an immunity (whether or not claimed), the Shipowner hereby
irrevocably agrees not to claim and hereby irrevocably waives such immunity.
The foregoing waiver of immunity shall have effect under the United States
Sovereign Immunities Act of 1976.

so long as those entries are each supported by a Certificate Authorizing
Advance and signed by the Shipowner and the Secretary.

         "Applicable Interest Rate" has the following meaning:

         (a) with respect to any portion of this Note that is funded by GOVCO
Incorporated (the "Primary Lender") through its issuance of commercial paper
notes and so long as the Primary Lender is the holder of the indebtedness
related to such funded portion, the sum of (i) the Primary Lender's weighted
average cost (defined below) related to the issuance of commercial paper notes
and other short-term borrowings or the sale of participation interests
(collectively, "Commercial Paper"), which in each case have been allocated by
the Primary Lender to this Note, which rate includes related issuance costs
incurred by the Primary Lender plus (ii) 0.30% per annum, as calculated by the
Indenture Trustee for each Interest Period (as defined below) based on the
weighted average cost of Commercial Paper specified in a written notice sent by
the Facility Agent to the Indenture Trustee, the Shipowner and the United States
of America, represented by the Secretary of Transportation, acting by and
through the Maritime Administrator (the "Secretary") at least five (5) Business
Days (as defined below) prior to each Interest Payment Date on which the
interest so calculated is payable. The Applicable Interest Rate shall, based on
such notice, be specified in a written notice sent by the Indenture Trustee to
the Shipowner, the Facility Agent and the Secretary at least four (4) Business
Days prior to each Interest Payment Date on which the interest so calculated is
payable. For purposes of the foregoing, the Primary Lender's "weighted average
cost" of Commercial Paper shall consist of (i) the actual interest or discount
paid to purchasers of Commercial Paper, (ii) the costs associated with the
issuance of the Commercial Paper and (iii) other borrowings the Primary Lender
may incur, including the amount to fund small or odd dollar amounts that are not
easily accommodated in the commercial paper market; and

         (b) with respect to any portion of the Note that is funded by Citibank,
N.A. (the "Alternate Lender") or to the extent that a portion of the Note held
by the Primary Lender is assigned to the Alternate Lender or to any other
assignee, then, from and after the applicable the Business Day on which the
Primary Lender or Alternative Lender, as applicable, shall have initially funded
the outstanding principal amount thereof or the effective date of such
assignment, as the case may be, a rate per annum equal to LIBOR (as defined
below) plus 0.30%; provided, however, that, if the Indenture Trustee shall have
received notice from the Alternate Lender or assignee that such Alternate Lender
or assignee shall have determined, prior to the commencement of any Interest
Period that: (A) dollar deposits of sufficient amount and maturity for a funding
under the Credit Agreement dated October 31, 2001 among the Shipowner, the
Primary Lender, the Alternate Lender, the Facility Agent and Citibank North
America, Inc., as Primary Lender Agent of any portion of this Note (an
"Advance") are not available to such Lender in the London Interbank Market in
the ordinary course of business; or (B) by reason of circumstances affecting the
relevant market, adequate and fair means do not exist for ascertaining the rate
of interest to be applicable to the Note; or (C) the relevant rate of interest
referred to in the definition of LIBOR which is to be used to determine the rate
of interest for this Note does not cover the funding cost to such Lender of
funding or maintaining this Note; or (D) such Lender is unable to establish
LIBOR for the relevant Interest Period; then, in any such event, the Indenture
Trustee shall give notice to the Shipowner and the Secretary of such condition
and interest shall, effective as of the date of such notice and so long as such
condition

                                       3

<PAGE>

shall exist, accrue during each applicable Interest Period at the
Federal Funds Rate (as defined below) plus 0.30%; provided, further, however
that if, in the applicable Lender's reasonable judgment, it becomes unlawful at
any time for such Lender to make or maintain fundings under the Note based upon
LIBOR, the Facility Agent on behalf of the Lender shall so notify the Indenture
Trustee and the Secretary, who shall give notice to the Shipowner of such
determination and, effective, as of the date of such notice and so long as such
condition shall exist, interest shall thereafter accrue during each applicable
Interest Period at the Federal Funds Rate plus 0.30%.

         "Business Day" means any day on which dealings in Dollar deposits are
carried on in the London interbank market and on which commercial banks in
London and New York City are open for domestic and foreign exchange business.

         "Interest Period" means, with respect to any Advance or portion
thereof, (i) the period commencing on the Advance Date relating thereto and
extending up to, but not including, the next Interest Payment Date; and (ii)
thereafter, the period commencing on each Interest Payment Date and extending up
to, but not including, the next Interest Payment Date; provided, that, in the
event the Primary Lender assigns its interest to the Alternate Lender in an
Advance or any portion thereof on a date other than an Interest Payment Date,
then, upon written notice from the Facility Agent to the Indenture Trustee of
such event, (i) such Interest Period shall end on the date on which the Primary
Lender shall so assign such Advance or such portion thereof and (ii) a new
Interest Period with respect to such Advance or such shall commence on such date
and shall end on the next Interest Payment Date.

         "Federal Funds Rate" means, for any period, a fluctuating interest rate
per annum equal for each day during such period to the weighted average of the
rates on overnight Federal funds transactions with members of the Federal
Reserve System arranged by Federal funds brokers, as published for such day (or,
if such day is not a Business Day, for the next preceding Business Day) by the
Federal Reserve Bank of New York, or, if such rate is not so published for any
day which is a Business Day, the average of the quotations for such day for such
transactions received by Citibank, N.A. from three Federal funds brokers of
recognized standing selected by it as specified by written notice from the
Facility Agent to the Shipowner, the Indenture Trustee and the Secretary
delivered on each Monday (or if such day is not a Business Day, on the next
succeeding Business Day) for the preceding calendar week.

         "LIBOR" means, in relation to any Interest Period, an interest rate per
annum equal to (i) the rate of interest per annum (rounded upward, if necessary,
to the nearest 1/16 of 1%) quoted by the principal London office of Citibank, N.
A., at approximately 11:00 a.m. (London time) on the Quotation Date for the
offering to leading banks in the London Interbank Market of U.S. Dollar deposits
for a period and in an amount comparable to such Interest Period and the
principal amount upon which interest is to be paid during such Interest Period;
divided by (ii) one hundred percent (100%) minus the Eurodollar Reserve
Percentage, as specified by the Facility Agent in a written notice to the
Shipowner, the Indenture Trustee and the Secretary given not later than one
Business Day prior to such Interest Period (or, if such Interest Period
commences as a result of an assignment from the Primary Lender to the Alternate
Lender, given not later than the second Business Day of such Interest Period).

         This Note is designated as the "United States Government Guaranteed
Ship Export Financing Note, Galileo Series", issued under a Trust Indenture
dated as of this date (said Trust Indenture, as the same may be amended,
modified or supplemented from time to time as permitted thereunder, herein
called the "Indenture"), among the Shipowner and U.S. Bank National Association,
as Indenture Trustee (said Indenture Trustee, and its successor as defined in
the Indenture, herein called the "Indenture Trustee") to aid in financing the
cost of the Vessel (as defined in the Indenture). Reference is hereby made to
the Indenture for a definition of all capitalized terms used herein and not
otherwise defined herein and a description of the rights, limitations of rights,
obligations, duties and immunities thereunder of the Shipowner and the Indenture
Trustee and the rights and limitations of rights of the Holder of this Note.

         In accordance with the terms of an Authorization Agreement dated as of
this date (herein as in effect, the "Authorization Agreement"), between the
Secretary and the Indenture Trustee and by endorsement of the guarantee of the
United States of America (herein called the "Guarantee") on this Note and the
authentication and delivery of the Guarantee by the Indenture Trustee, all
pursuant to Title XI of the Merchant Marine Act, 1936, as amended and in effect
on this date (herein called the "Act"), this Note is guaranteed by the United
States of America as provided in the Authorization Agreement and in the
Guarantee endorsed hereon. Reference is hereby made to the Authorization
Agreement for a description of the rights, limitations of rights, obligations,
duties and immunities thereunder of the Secretary and the Indenture Trustee and
the rights and limitations of rights of the Holder of this Note.

         Section 1103(d) of Title XI of the Act provides that:

         "The full faith and credit of the United States is pledged to the
payment of all guarantees made under this title with respect to both principal
and interest, including interest, as may be provided for in the guarantee,
accruing between the date of default under a guaranteed obligation and the
payment in full of the guarantee."

         If an Indenture Default (defined in Section 6.01 of Exhibit 1 to the
Indenture as a Payment Default or the giving of a Secretary's Notice) shall have
occurred and be continuing, the Indenture Trustee, as provided in the Indenture,
shall promptly, but not later than sixty (60) days from the date of such
Indenture Default, demand payment by the Secretary of the Guarantee, whereupon
the entire unpaid principal amount of this Note then Outstanding and all unpaid
interest thereon shall become due and payable in United States currency on the
first to occur of the date which is thirty (30) days from the date of such
demand or the date on which the Secretary pays the Guarantee. If no demand for
payment of the Guarantee shall have been made by the Indenture Trustee on or
before the thirtieth (30th) day following an Indenture Default, the Holder of
this Note may, in the manner provided in the Indenture, make such demand in
place of the Indenture Trustee. In the event of an Indenture Default of which
the Secretary has actual knowledge, the Secretary, as provided in the
Authorization Agreement, will publish notice in the Authorized Newspapers, which
shall include "The Wall Street Journal" (all editions) and "The Journal of
Commerce", of the occurrence of such Indenture Default within thirty (30) days
from the date of such Indenture Default unless demand for payment under the

                                       5

<PAGE>

Guarantee shall previously have been made by the Indenture Trustee, but any
failure to publish such notice or any defect therein shall not affect in any way
any rights of the Indenture Trustee or any Holder of this Note in respect of
such Indenture Default.

         Within thirty (30) days from the date of any demand for payment of the
Guarantee, the Secretary shall pay to the Indenture Trustee, as agent and
attorney-in-fact for the Holder of this Note, all of the unpaid interest to the
date of such payment on, and the unpaid balance of the principal of, this Note
in full, in United States currency in cash; provided that, in the case of a
demand made as a result of a Payment Default, the Secretary shall not be
required to make any such payment if within such thirty (30) day period (and
prior to any payment of the Guarantee by the Secretary) the Secretary finds
either that there was no Payment Default or that such Payment Default was
remedied prior to the demand for payment of the Guarantee, in which event the
Guarantee shall continue in full force and effect.

         The Holder of this Note by the purchase and acceptance hereof, hereby
irrevocably appoints the Indenture Trustee as agent and attorney-in-fact for the
purpose of making any demand for payment of the Guarantee and (in the case of
the Indenture Trustee) of receiving and distributing such payment; provided that
no action or failure to act by the Indenture Trustee shall affect the right of
the Holder of this Note to take any action whatsoever permitted by law and not
in violation of the terms of this Note or of the Indenture.

         In the event of (a) a default, continuing for twenty-five (25) days, in
the payment of the principal of or interest on this Note when due or (b) any
default under the Security Agreement, the Mortgage or any related agreement
between the Secretary and the Shipowner, the Secretary shall have the right to
and may, in its discretion by written notice given to the Indenture Trustee on
or after said twenty-five (25) day period or after such default but prior to
receipt by the Secretary of a demand in accordance with the Indenture for
payment under the Guarantee, assume all of the rights and obligations of the
Shipowner under the Indenture and the Note and, if such default relates to the
payment of the principal of and interest on the Note, make all payments then in
default under the Note.

         Any amount payable by the Secretary under the Guarantee shall not be
subject to any claim or defense of the United States of America, the Secretary,
or others, whether by way of counter-claim, set-off, reduction or otherwise.
Further, the Holder of this Note shall have no right, title or interest in any
collateral or security given by the Shipowner or any other person to the
Secretary.

         After payment of the Guarantee by the Secretary to the Indenture
Trustee, this Note (1) if it has not then been surrendered for cancellation or
cancelled, shall represent only the right to receive payment in cash of an
amount (less the amount, if any, required to be withheld in respect of transfer
or other taxes on payments to the Holder of this Note) equal to the unpaid
principal amount hereof and the unpaid interest accrued hereon to the date on
which the Secretary shall have paid the Guarantee in full in cash to the
Indenture Trustee, (2) shall otherwise no longer constitute or represent an
obligation of the Shipowner, and (3) shall not be entitled to any other rights
or benefits provided in the Indenture, subject to Section 6.08 of the Indenture.

this Note, or (2) shall have been so held and shall thereafter have been paid to
the Shipowner after having been unclaimed for six (6) years after the date of
maturity thereof (whether by redemption or otherwise) or the date of payment of
the Guarantee, except for the right, if any, of the Holder to receive payment
from the Shipowner of any amounts paid to the Shipowner as provided in (2) above
with respect to this Note, all subject, however, to the provisions of Section
6.08 of Exhibit 1 to the Indenture.

         This Note is transferable upon obtaining the prior written consent of
the Secretary, and to the extent permitted under Section 11.03 of the Credit
Agreement, by the registered Holder or by his duly authorized attorney, at the
Corporate Trust Office of the Indenture Trustee, upon surrender or cancellation
of this Note, accompanied by an instrument of transfer in form satisfactory to
the Shipowner and the Indenture Trustee, duly executed by the registered Holder
hereof or his attorney duly authorized in writing, and thereupon a new, fully
registered Note or Notes of like series and maturity for the same aggregate
principal amount will be issued to the transferee in exchange therefor, each in
the principal amount of One Thousand Dollars ($1,000) or any integral multiple
thereof subject to the provisions of the Indenture. The Indenture provides that
the Shipowner shall not be required to make transfers or exchanges of this Note
(1) for a period of fifteen (15) days immediately prior to an interest payment
date or (2) after demand for payment of the Guarantee and prior to payment
thereof or rescission of such demand as provided in Section 6.02(a) of Exhibit 1
to the Indenture or (3) if all or any portion thereof has been selected for
repayment, prepayment or redemption in whole or in part, except, in the case of
a partial repayment, prepayment or redemption, as to the unredeemed portion
being repaid, prepaid or redeemed in part.

         The Shipowner, the Secretary, the Indenture Trustee and any office or
agency for the payment of Notes may deem and treat the person in whose name this
Note is registered as the absolute owner thereof for all purposes, and neither
the Shipowner, the Secretary, the Indenture Trustee, nor any such office or
agency shall be affected by any notice to the contrary, whether this Note shall
be past due or not.

         No recourse shall be had for the payment of principal of, or the
interest or premium (if any) on, this Note, or for any claim based hereon or on
the Indenture, against any member or officer of the Shipowner or any
incorporator or any past, present or future subscriber to the capital stock,
stockholder, officer or director of any member of the Shipowner or of any
successor, as such, either directly or through the Shipowner or any such
successor to the Shipowner or its members, under any constitution, statute or
rule of law or by the enforcement of any assessment, or otherwise, all such
liability being expressly waived and released by the acceptance of this Note and
by the terms of the Indenture; provided that nothing in this paragraph shall be
deemed a waiver of any claim against any such member, officer thereof, or any
incorporator, subscriber, stockholder, officer or director of any member for
fraud, misrepresentation, misappropriation of funds or willful misconduct on the
part of such person.

         The Guarantee of the United States extends only to the principal and
interest owed under this Note and only to the extent specified herein. The
United States does not guarantee the payment of any other indebtedness of the
Shipowner to the Holder or any other
