                                   SHIPOWNERS

     THIS COMMITMENT TO GUARANTEE OBLIGATIONS, dated June 7, 2002 (the
"Guarantee Commitment"), made and entered into by the UNITED STATES OF AMERICA
(the "United States"), represented by the SECRETARY OF TRANSPORTATION, acting by
and through the MARITIME ADMINISTRATOR (the "Secretary"), and accepted on said
date by K-SEA TRANSPORTATION LLC, a Delaware limited liability company ("K-Sea")
and EW HOLDING CORP., a New York corporation ("EW Holding" and with K-Sea
collectively, "the Shipowners" and each a "Shipowner").

                                    RECITALS:

     A.   K-Sea has entered into the Construction Contract dated March 23, 2001
with Bollinger Gretna, LLC, a Louisiana limited liability company (the
"Shipyard" or "Builder") for the Construction of four vessels, identified as
Builder's Hull No. 416, to be named DBL-101 (the "EW Vessel"), and Builder's
Hulls Nos. 417, 421 and 422, to be named DBL-81, DBL-82 and DBL-102,
respectively, (the "K-Sea Vessels" and each a "K-Sea Vessel"; when used
collectively with the EW Vessel, the "Vessels"; when used singularly, the
"Vessel") to be built in accordance with the Construction Contract.

     B.   K-Sea assigned a continuing security interest in all of its right,
title and interest in and to the Construction Contract to The CIT
Group/Equipment Financing, Inc. ("CIT") pursuant to a construction contract
assignment dated as of July 27, 2001 (the "CIT Assignment") by and between K-Sea
and CIT.

     C.   In connection with a like-kind exchange transaction, K-Sea assigned
all of its rights, title and interest in and to (but not its obligations

under) the Construction Contract with respect to the EW Vessel to Investment
Property Exchange Services, Inc. ("IPX") pursuant to a Partial Assignment of
Rights Under Vessel Construction Agreement (EX-12-2284) dated October 11, 2001
subject and subordinate to the rights of CIT as secured party under the CIT
Assignment. IPX and EW Holding entered into an agreement dated October 11, 2001
(the "Exchange Agreement") pursuant to which IPX has agreed to act as an escrow
agent for EW Holding and to use funds received by EW Holding to make payments to
the Shipyard required under the Construction Contract and to arrange for the
Shipyard to deliver Builder's Hull No. 416 and title thereto directly to EW
Holding upon completion.

     D.   EW Holding will be the sole owner of the EW Vessel and K-Sea will be
the sole owner of the K-Sea Vessels, on their respective Delivery Dates.

     E.   To aid in financing the Construction of the Vessels, the Shipowners
will borrow an aggregate principal amount equal to the sum of eighty-seven and
one half percent (87.5%) of the Actual Cost of each of the Vessels, as of the
Closing Date. To accomplish such financing, the Shipowners have accepted this
Guarantee Commitment subject to the terms and conditions set forth herein.

     F.   The Shipowners have entered into the Bond Purchase Agreement providing
for the sale and delivery, on the Closing Date, of obligations in four (4)
series in the aggregate principal amount of Forty Million Four Hundred Forty-One
Thousand United States Dollars (US$40,441,000) to be designated "United States
Government Guaranteed Ship Financing Obligations, K-Sea Series 2002-1, 2002-2,
2002-3 and 2002-4" respectively (the "Obligations") having the maturity dates
and interest rate set forth herein.

     G.   The Authorization Agreement, Contract MA-13780 is intended to be
entered into on the Closing Date between the Secretary and the Indenture Trustee
and will authorize the Indenture Trustee to endorse and execute, by means of
facsimile signature of the Secretary and the facsimile seal of the Department of
Transportation, on each of the Obligations issued thereunder and to authenticate
a guarantee by the Secretary of the payment in full of all the unpaid interest
on, and the unpaid balance of the principal of, each Obligation, including
interest accruing between the date of default under such Obligation and the date
of payment by the Secretary (individually, a "Guarantee" and, collectively, the
"Guarantees").

     H.   As security for the Guarantees and the Secretary's Note, the
Shipowners will execute and deliver the Security Agreement, Contract No.
MA-13781, and the following agreements shall be executed and delivered: the
Indenture, the Authorization Agreement, Contract No. MA-13780, the Secretary's
Note, the Financial Agreement, Contract MA-13784, the Depository Agreement,

MA-13782, in favor of the Secretary as mortgagee on the Delivery Date of the EW
Vessel. K-Sea shall execute and deliver the Fleet Mortgage, Contract No.

Increased Security relating to the delivered Vessel.

                                   WITNESSETH:

     That under the provisions of Title XI of the Merchant Marine Act, 1936, as
amended and in consideration of (i) the covenants of the Shipowners contained
herein and (ii) other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Secretary hereby commits
itself as herein provided.

                                    ARTICLE I
                    FINDINGS AND DETERMINATIONS OF SECRETARY

     Pursuant to Section 1104A(b)(l) of Title XI, the Secretary has approved the

resources and other qualifications necessary to the adequate operation and
maintenance of the Vessels.

     Pursuant to Section 1104A(b)(2) of Title XI, the Secretary has determined
that the aggregate of the Actual Cost of the Vessels is Forty-Six Million Two
Hundred Twenty Thousand Six Hundred Sixteen United States Dollars
(US$46,220,616). The Secretary has determined that the Actual Cost of the EW
Vessel is Twelve Million Four Hundred Sixty Three Thousand Five Hundred
Thirty-Five United States Dollars (US$12,463,535), the Actual Cost of the K-Sea
Vessel named DBL-81 is Eleven Million Eight Thousand Two Hundred Thirty-Two
United States Dollars (US$11,008,232), the Actual Cost of the K-Sea Vessel named
DBL-82 is Ten Million Seven Hundred Fifteen Thousand Nine Hundred Sixty-One
United States Dollars (US$10,715,961) and the Actual Cost of the K-Sea Vessel
named DBL-102 is Twelve Million Thirty-Two Thousand Eight Hundred Eighty-Eight
United States Dollars (US$12,032,888). Prior to the Closing Date, the Secretary,
in its discretion, may redetermine the Actual Cost of one or more of the
Vessels. On the Closing Date, the aggregate principal amount of the Obligations
will not exceed the sum of eighty-seven and one half percent (87.5%) of the
Actual Cost of each of the Vessels.

     Pursuant to Sections 1104A(b)(3), 1104A(b)(4) and 1104A(b)(5) of Title XI,
the Secretary has determined that: (1) the maturity date of the Obligations is

                                        3

satisfactory, (2) payments of principal required by the Obligations are
satisfactory and (3) the interest rate to be borne by the Obligations to be
issued on the Closing Date is reasonable.

     Pursuant to Section 1104A(d) of Title XI, the Secretary has found that the
Shipowners' proposed use of the Vessels will be economically sound.

rights IN REM, and statutory liens incident to current operations unless such
statutory liens are subordinate to the Mortgage.

     (g)  VESSELS CONDITION AND MAINTENANCE. (1) Each Vessel shall be
constructed, maintained and operated so as to meet, at all times, the highest
classification, certification, rating and inspection standards for Vessels of

which is not classed, then the Shipowner shall, at all times, at its own cost
and expense maintain and preserve each Vessel, so far as may be practicable, in
at least as good order and condition, ordinary wear and tear excepted, as at the
Delivery Date of such Vessel, and shall perform or cause to be performed at
least once every five years and at any other time reasonably required by the
Secretary, a survey and inspection of the Vessels by an independent marine
surveyor approved by the Secretary; and PROVIDED THAT, no such surveys will be

     SECTION 2.03.  MAINTENANCE OF CONSTRUCTION CONTRACT. (a) The Construction
Contract shall be maintained in full force and effect insofar as it relates to
the due performance by the Shipowner and the Shipyard of all their respective
obligations thereunder and the Shipowner shall not, without the Secretary's
prior written consent, amend, modify, assign or terminate the Construction
Contract or consent to any change in the Construction Contract which releases
the Shipyard from its obligations to comply with the provisions of the
Construction Contract or any applicable laws, treaties, conventions, rules and
regulations; PROVIDED THAT, the Secretary's prior written consent shall not be
necessary, but prompt written notice to the Secretary shall be given for (1) any
mandatory or regulatory change to the Construction Contract as a result of any
requirements of any governmental agency, or (2) any non-mandatory changes that
Shipyard and Shipowner desire to make which do not exceed, with respect to any
item of the Vessel's construction, one (1%) percent of the Vessels Contract
Price and which do not, in the aggregate, cause the Vessels Contract Price to be
increased more than five (5%) percent or the delivery and completion date of the
Vessel to be extended more than ten (10) days. Notwithstanding the foregoing, no
change shall be made in the general dimensions and/or characteristics of the
Vessels which changes the capacity of the Vessels to perform as originally
intended by the Construction Contract without the Secretary's prior written
consent. The Secretary will nonetheless retain its authority to review work done
under a change order to ascertain whether the work should be included in Actual
Cost and whether the price charged is fair and reasonable. No withdrawals may be

by the Secretary. The Shipowner shall provide 30 days prior written notice to
the Secretary of all insurance renewals.

of issue of the policies in question) forms of American Institute of Marine
Underwriters' policies approved by the Secretary and/or policies issued by or
for the Maritime Administration (or under such other forms of policies as the

other forms of policies as the Secretary may approve in writing) insuring such
Vessel against the usual risks covered by such forms.

            (3) Notwithstanding the foregoing, the Shipowner, with the
Secretary's prior written consent, shall have the right to self-insure up to the
amount specified in the Special Provisions hereof for any loss resulting from
any one accident or occurrence (other than an actual or constructive total loss
of any Vessel).

     (c)  All policies of insurance under this Section shall provide, so long as
this Security Agreement has not been discharged, that payment of all losses
shall be made payable to the Secretary for distribution by him to himself, the
Shipowner and (in the case of the insurance required by paragraph (a) of this
Section) the Shipyard, except that (i) as provided in paragraph (e) of this
Section and (ii) under the policies required by paragraph (b) of this Section,
payment of all losses up to the amount specified in the Special Provisions
hereof by all insurance underwriters with respect to any one accident,
occurrence or event may be made directly to the Shipowner unless there is an
existing Default, or if the Secretary shall have assumed the Shipowner rights
and duties under the Indenture and the Obligations and made any payments in
default under the terms of Section 6.09 of the Indenture, in which event payment
of all losses shall be made payable to the Secretary as aforesaid.

     Any such insurance recoveries to which the Secretary shall be so entitled
shall be applied as follows:

            (1) In the event that insurance becomes payable under said policies
on account of an accident, occurrence or event not resulting in an actual or
constructive total loss or an agreed or compromised total loss of any Vessel,
the Secretary shall (A) if there is no existing Default and if none of the
events described in Section 2.07 has occurred, in accordance with a Shipowner's
Request, pay, or consent that the underwriters pay, direct for repairs,
liabilities, salvage claims or other charges and expenses (including sue and
labor charges due or paid by the Shipowner) covered by the policies, or (to the
extent that, as stated in an Officer's Certificate delivered to the Secretary,
accompanied by written confirmation by the underwriter or a surveyor or
adjuster, the damage shall have been repaired and the cost thereof paid of such
liabilities, salvage claims, or other charges and expenses discharged or paid)
reimburse, or consent that the underwriters reimburse, the Shipowner therefor
and (after all known damage with respect to the particular loss shall have been
repaired, except to the extent the Shipowner, with the Secretary's written
consent, deems the said repair inadvisable, and all known costs, liabilities,
salvage claims, charges and expenses, covered by the policies, with respect to
such loss shall have been discharged or paid, as stated in an Officer's
Certificate delivered to the Secretary, accompanied by written confirmation by
the underwriters or a surveyor or adjuster) pay, or consent that the
underwriters pay, any balance to the Shipowner; or (B) if there is an existing
Default, in accordance with a Request of Shipowner, pay, or consent that the
underwriters pay, direct for the Shipowner's proportion of such repairs,
liabilities, salvage claims or other charges and expenses (including sue and
labor charges due or paid by the Shipowner) covered by the policies and hold any
balance until the same may be paid or applied under clauses

                                        8

(A), (C) or (D) of this subsection, whichever is applicable; or (C) if the
Guarantees shall have terminated pursuant to Section 3.02(c) or if the Secretary
shall have assumed the Shipowner's rights and duties under the Indenture and the
Obligations and made any payments in default under the terms of Section 6.09 of
the Indenture and none of the events described in Section 2.07 has occurred,
apply the insurance as provided in Section 6.05; or (D) if the Guarantees shall
have terminated pursuant to Section 3.02(b) or (d), pay the insurance to the
Shipowner;

            (2) In the event of an accident, occurrence or event resulting in an
actual or constructive total loss of any Vessel prior to the Delivery Date of
such Vessel, the Shipowner shall forthwith deposit with the Secretary any
insurance moneys which the Shipowner receives on account thereof under policies
of insurance required by paragraph (a) of this Section, and any such insurance
moneys shall be held by the Secretary for 10 days (or such lesser or further
time as the Shipowner and the Secretary may agree upon). Upon the expiration of
said period of time, (A) if there is no existing Default and if the Shipowner,
the Shipyard and the Secretary shall have elected not to construct such Vessel
under the Construction Contract, then said insurance moneys shall be applied, to
the extent necessary and required pursuant to Section 2.07; or (B) if there is
no existing Default and if the Shipowner, the Shipyard and the Secretary shall
not have made the election contemplated by clause (A) of this subsection, then
said insurance moneys (together with the Shipowner's funds to the extent, if
any, required by the Secretary for deposit on account of interest under clause
(ii) below) shall be deposited in the Escrow Fund, in such amount and to the
extent available, so that the moneys in the Escrow Fund after such deposit shall
be equal to (i) the principal amount of the Proportionate Part of the
Outstanding Obligations relating to such Vessel at the time of such deposit and
(ii) such interest on said deposit, if any, as may be required by the Secretary
(said moneys to be subject to withdrawal in the same manner as moneys originally
deposited in said Escrow Fund); and the balance, if any, of such insurance
moneys held by the Secretary shall be paid to the Shipowner; and

            (3) In the event of an accident, occurrence or event resulting in an
actual or constructive total loss or an agreed or compromised total loss of any
Vessel, whether prior to or after the Delivery Date of such Vessel, and the
insurance moneys have not been applied as provided in paragraph (c)(2) of this
Section, the Shipowner shall forthwith deposit with the Secretary any insurance
moneys which the Shipowner receives on account thereof under policies of
insurance required by this Section, and any such insurance moneys received by
the Secretary, whether from the Shipowner or otherwise, or held by the Secretary
pursuant to paragraph (c)(2) of this Section, shall (A) if there is no existing
Default, be applied, to the extent necessary, pursuant to Section 2.07; (B) if
there is an existing Security Default, be held until the same may be applied
under clauses (A), (C), or (D) of this subsection, whichever is applicable; (C)
if the guarantees shall have terminated pursuant to Section 3.02(c) or if the
Secretary shall have assumed the Shipowner's rights and duties under the
Indenture and the Obligations and made any payments in default under the terms
of Section 6.09 of the Indenture, be applied as provided in Section 6.05;
PROVIDED THAT, notwithstanding the foregoing clauses (A), (B) and (C) of this
subsection, the Shipowner shall not be required to so deposit with the Secretary
insurance moneys in an amount which, together with funds otherwise available for
the redemption of Obligations is in excess of that required for the redemption
of the Proportionate Part of the Outstanding Obligations pursuant to Section
3.05 of the Indenture and for

                                        9
<Page>

the payment to the Secretary of a Proportionate Part of all other sums that may
be secured by this Security Agreement and the Mortgage; or (D) if the Guarantees
shall have terminated pursuant to Section 3.02(b) or 3.02(d), be paid to the
Shipowner.

     (d)  In the event of an accident, occurrence or event resulting in a
constructive total loss of any Vessel, the Secretary shall have the right (with
the prior written consent of the Shipowner, unless there is an existing Default,
and at any time prior to the Delivery Date of such Vessel also with the prior
written consent of the Shipyard) to claim for a constructive total loss of such
Vessel. If (1) such claim is accepted by all underwriters under all policies
then in force as to such Vessel under which payment is due for total loss and
(2) payment in full is made in cash under such policies to the Secretary, then
the Secretary shall have the right to abandon such Vessel to the underwriters of
such policies, free from lien of this Security Agreement and the Mortgage.

     (e)  Commencing on the Delivery Date of each Vessel, the Shipowner shall,
without cost to the Secretary, keep each such Vessel insured against marine and
war risk protection and indemnity risks and liabilities by policies of insurance
approved by the Secretary as to form and amount; PROVIDED THAT, (1) the
Shipowner shall, as soon as possible before such Delivery Date, present any such
policy to the Secretary (who shall promptly approve or disapprove the same), (2)
any approval of a policy under this subsection shall be effective until the end
of the policy period or until 60 days after the Secretary shall notify the
Shipowner of a desired change in the form and/or amount thereof, whichever shall
first occur, and (3) war protection and indemnity insurance shall be required
unless the Secretary gives written notice to the Shipowner stating that such
insurance is not required.

     Such policies may provide that (1) if the Shipowner shall not have incurred
the loss, damage, or expense in question, any loss under such insurance may be
paid directly to the Person to whom any liability covered by such policies has
been incurred (whether or not a Default then exists), and (2) if the Shipowner
shall have incurred the loss, damage or expense in question, any such loss shall
be paid to the Shipowner in reimbursement if there is no existing Default of
which the underwriter has written notice from the Shipowner or the Secretary,
or, if there is such an existing Default, to the Secretary to be held and
applied as follows: (A) applied as provided in Section 6.05 in the event the
Guarantees shall have terminated pursuant to Section 3.02(c) or if the Secretary
shall have assumed the Shipowner's rights and duties under the Indenture and the
Obligations and made any payments in default under the terms of Section 6.09 of
the Indenture, or (B) to the extent not theretofore applied pursuant to Section
6.05, paid forthwith to the Shipowner upon its Request in the event there is no
existing Default or the Guarantees shall have terminated pursuant to Section
3.02(b) or (d) at the date of delivery of such Request; PROVIDED THAT,
irrespective of the foregoing, with the Secretary's prior written consent, the
Shipowner shall have the right to self-insure in an amount up to the limit
specified in the Special Provisions hereof with respect to each accident,
occurrence or event, except that, with respect to cargo or property carried, the
Shipowner, with the Secretary's prior written consent, shall have the right to
self-insure in an amount up to the limit specified in the Special Provisions
hereof with respect to each cargo or property carried.

     (f)  All insurance required under this Section shall be placed and kept
with the United States Government or with American and/or British (and/or other
foreign, if permitted by the Secretary in

                                       10
<Page>

writing) insurance companies, underwriters' association or underwriting funds
approved by the Secretary. All insurance required under this subsection shall be
arranged through marine insurance brokers and/or underwriting agents as chosen
by the Shipowner and approved by the Secretary.

     (g)  The Secretary shall not have the right to enter into an agreement or
compromise providing for an agreed or compromised total loss of any Vessel
without prior written consent of (i) the Shipyard (prior to the Delivery Date of
such Vessel) and (ii) (unless there is an existing Default) the Shipowner. If
(1) the Shipowner shall have given prior consent thereto or (2) there is an
existing Default, the Secretary shall have the right in his discretion, and with
the prior written consent of the Shipyard prior to the Delivery Date of such
Vessel, to enter into an agreement or compromise providing for an agreed or
compromised total loss of such Vessel; PROVIDED THAT, if the aggregate amount
payable to the Shipowner and/or the Secretary under such agreement or
compromise, together with funds held by the Secretary and available for the
redemption of Obligations, is not sufficient to redeem or pay the Proportionate
Part of the Outstanding Obligations pursuant to Section 2.07, the Secretary
shall not enter into such agreement or compromise without the Shipowner's prior
written consent.

     (h)  During the continuance of (1) a taking or requisition of the use of
any Vessel by any government or governmental body, or (2) a charter, with the
Secretary's prior written consent, of the use of any Vessel by the United States
Government or by any governmental body of the United States, or by any other
government or governmental body, the provisions of this Section shall be deemed
to have been complied with in all respects if such government or governmental
body shall have agreed to reimburse, in a manner approved by the Secretary in
writing, the Shipowner for loss or damage covered by the insurance required
hereunder or resulting from the risks under paragraphs (a), (b), and (e) of this
Section or if the Shipowner shall be entitled to just compensation therefor. In
addition, the provisions of this Section shall be deemed to have been complied
with in all respects during any period after (A) title to any Vessel shall have
been taken or requisitioned by any government or governmental body or (B) there
shall have been an actual or constructive total loss or an agreed or compromised
total loss of any Vessel. In the event of any taking, requisition, charter or
loss contemplated by this paragraph, the Shipowner shall promptly furnish to the
Secretary an Officer's Certificate stating that such taking, requisition,
charter or loss has occurred and, if there shall have been a taking, requisition
or charter of the use of any Vessel, that the government or governmental body in
question has agreed to reimburse the Shipowner, in a manner approved by the
Secretary, for loss or damage resulting from the risks under paragraphs (a),
(b), and (e) of this Section or that the Shipowner is entitled to just
compensation therefor.

     (i)  All insurance required (A) under paragraph (a) of this Section shall
be taken out in the names of the Shipowner, the United States and the Shipyard
as assureds, and (B) under paragraphs (b) and (c) of this Section shall be taken
out in the names of the Shipowner and the United States as assureds. All
policies for such insurance so taken out shall, unless otherwise consented to by
the Secretary, provide that (1) there shall be no recourse against the United
States for the payment of premiums or commissions, (2) if such policies provide
for the payment of club calls, assessments or advances, there shall be no
recourse against the United States for the payment thereof, and (3) at least 10
days' prior written notice of any cancellation for the nonpayment of premiums,
commissions,

                                       11
<Page>

club calls, assessments or advances shall be given to the Secretary by the
insurance underwriters.

     (j)  The Shipowner shall not, without the Secretary's prior written
consent, (1) do any act, nor voluntarily suffer or permit any act to be done,
whereby any insurance required by this Section shall or may be suspended,
impaired or defeated or (2) suffer or permit any Vessel to engage in any voyage
or to carry any cargo not permitted under the policies of insurance then in
effect without first covering such Vessel with insurance satisfactory in all
respects for such voyage or the carriage of such cargo; PROVIDED THAT, this
paragraph shall be subject to the requirements of any military authority of the
United States and shall not apply in the case of such Vessel if and so long as
the title or use of such Vessel shall have been taken, requisitioned or
chartered by any government or governmental body as contemplated by Section
2.07.

     (k)  In the event that any claim or lien is asserted against any Vessel for
loss, damage or expense which is covered by insurance hereunder and it is
necessary for the Shipowner to obtain a bond or supply other security to prevent
arrest of such Vessel or to release such Vessel from arrest on account of said
claim or lien, the Secretary, on the Shipowner's Request, may, at the
Secretary's sole option, assign to any Person executing a surety or guaranty
bond or other agreement to save or release such Vessel from such arrest, all
right, title and interest of the Secretary in and to said insurance covering
such loss, damage or expense as collateral security to indemnify against
liability under said bond or other agreement.

     (l)  Except as the Secretary shall otherwise direct by notice in writing to
the Shipowner, the Shipowner shall deliver to the Secretary the original
policies evidencing insurance maintained under this Section; PROVIDED THAT, if
any such original policy shall have been delivered previously to the Secretary
or to a mortgagee by the Shipowner under another ship mortgage of the Shipowner,
the Shipowner shall deliver a duplicate or pro forma copy of such policy to the
Secretary. The Secretary or any agent thereof (who may also be an agent of the
issuer) shall at all times hold the policies delivered as aforesaid; PROVIDED
THAT, if one or more of said policies are held by an agent of the Secretary, the
Shipowner shall, upon the Secretary's request, deliver a duplicate or pro forma
copy thereof to the Secretary, and PROVIDED FURTHER, that if the Shipowner shall
deliver to the Secretary a Request (1) stating that delivery of such policy to
the insurer is necessary in connection with the collection, enforcement or
settlement of any claim thereunder (including claims for return premiums and any
other amounts payable by the insurer) and (2) setting forth the name and address
of the Person to whom such policy is to be delivered or mailed for such purpose,
and if the Secretary approves such Request, the Secretary shall, at the
Shipowner's expense, deliver or mail (by registered or certified mail, postage
prepaid) such policy in accordance with such Request, accompanied by a written
direction to the recipient to redeliver such policy directly to the Secretary or

provided in Section 6.05; or

            (4) if the Guarantees shall have terminated pursuant to Section

     This Vessel is owned by (INSERT NAME OF SHIPOWNER), a (INSERT
     JURISDICTION) corporation ("Shipowner"), and is covered by a
     First Preferred Ship Mortgage in favor of the United States of
     America, under authority of Chapter 313, Title 46 of the United
     States Code. Under the terms of said Mortgage neither the
     Shipowner, any charterer, the master or agent of this Vessel nor
     any other person has any right, power or authority to create,
     incur or permit to be placed or imposed upon this Vessel any lien
     other than statutory liens incident to current operations that
     are subordinate to the Mortgage."

     SECTION 2.09.  COMPLIANCE WITH 46 U.S.C. CHAPTER 313. The Shipowner shall
comply with and satisfy all of the provisions of Chapter 313, in order to
establish and thereafter to maintain the Mortgage as a preferred mortgage upon
each Vessel.

     SECTION 2.10.  PERFORMANCE OF SHIPOWNER'S AGREEMENTS BY THE SECRETARY. If
the Shipowner shall fail to perform any of its agreements hereunder or under the
Mortgage, the Secretary may, in its discretion, at any time during the
continuance of an event which by itself, with the passage of time, or the giving
of notice, would constitute a Default, perform all acts and make all necessary
expenditures to remedy such failure. Notwithstanding the foregoing, the
Secretary shall not be obligated to (and shall not be liable for the failure to)
perform such acts and make such expenditures. All funds advanced and expenses
and damages incurred by the Secretary relating to such compliance

                                       14
<Page>

shall constitute a debt due from the Shipowner to the Secretary and shall be
secured hereunder and under the Mortgage prior to the Secretary's Note and shall
be repaid by the Shipowner upon demand, together with interest at the rate that
would have been paid by the Department of Treasury on the expended funds plus
1%.

     SECTION 2.11.  UNIFORM COMMERCIAL CODE FILINGS; FURTHER ASSURANCES. The
Shipowner shall (a) furnish evidence satisfactory to the Secretary that
financing statements under the UCC shall have been filed against the Shipowner
and/or the Shipyard in all offices in which it may be necessary or advisable in
the opinion of the Secretary to perfect the Secretary's security interests, and
(b) from time to time execute and deliver such further instruments and take such
action as may reasonably be required to more effectively subject the Security to
the lien of this Security Agreement and the Mortgage as contemplated thereby,
including but not limited to, legal opinions from an independent counsel for the
Shipowner to the effect that all UCC Financing Statements have been filed to
perfect the Secretary's interests in the Security as valid and enforceable first
priority perfected security interests.

     SECTION 2.12.  MODIFICATION OF FORMATION AGREEMENTS. (a) If the Shipowner
is organized as a general partnership, limited partnership, limited liability
company or joint venture, then for so long as there is Outstanding any
indebtedness to the United States of America pursuant to the Act, the
partnership agreement, operating agreement, limited liability agreement, joint
venture agreement (or any agreement constituting such an entity) shall not be
amended, modified or voluntarily terminated without the Secretary's prior
written consent.

     (b)  In the event where any action by the Shipowner, any member of the
Shipowner or the management of the Shipowner results or would result in
dissolution of the Shipowner pursuant to its limited liability company agreement
or governing law, each member of the Shipowner shall forthwith take all steps
necessary to reform and reestablish the Shipowner.

     SECTION 2.13.  MEMBERS OF LIMITED LIABILITY COMPANIES. All existing and
future members of a Shipowner which is a limited liability company (each being a
"Member"), upon becoming a Member, shall forthwith enter into an agreement with
the Secretary, in form and substance satisfactory to the Secretary, whereby each
Member agrees: (1) that any amounts owed by the Shipowner to a Member with
respect to its interest (as that or the equivalent term is used in the
Shipowner's limited liability company agreement) (the "Distributions") shall be
subordinated to the Shipowner's payment of the Secretary's Note and debts under
the Security Agreement, provided that such Distributions may be paid to the
extent the Shipowner is permitted to pay dividends under the Financial
Agreement; (2) that in the event of default by the Shipowner under the Security
Agreement, the Member shall be subordinated in its rights to receive any
Distribution or to be paid any sums whatsoever by the Shipowner until the
Secretary has made a full recovery of any and all amounts owed under the
Secretary's Note and the Security Agreement.

     SECTION 2.14.  CONCERNING THE PERFORMANCE AND PAYMENT BONDS. During the
Construction, the Shipowner shall cause to be maintained Performance Bonds and
Payment Bonds naming the Shipowner and the Secretary as co-obligees (the "Surety
Bonds") in form and substance

                                       15
<Page>

satisfactory to the Secretary, to be obtained by the Shipyard in the amount of
the Construction Contract, issued by such surety company or companies as shall
be satisfactory to the Secretary (the "Surety"). In the event that the price for
the work to be performed under the Construction Contract is increased, then the
Surety Bonds shall be increased simultaneously in a corresponding amount. The
Shipowner hereby agrees that the Secretary shall be the sole loss payee under
the Surety Bonds and the Surety shall pay such amounts directly to the Secretary
for distribution to the co-obligees as their interests may appear. The Shipowner
hereby agrees that its interest as a co-obligee under each of the Surety Bonds
is and shall be, upon the occurrence of a Default under the Security Agreement,
fully subject and subordinate to the rights and interests of the Secretary
therein. In the event of a default under the Security Agreement, which default
results in a payment under any of the Surety Bonds, then the Surety Bonds
proceeds shall be distributed by the Secretary in accordance with the provisions
of Section 6.05 hereof. The Shipowner hereby irrevocably appoints the Secretary,
the true and lawful attorney of the Shipowner, in its name and stead, to execute
all consents, approvals, settlements and agreements on behalf of the Shipowner
with respect to any rights related to the Surety Bonds.

     (b)  The Obligees of all the Obligations then Outstanding shall have
elected to terminate the Guarantees, and the Secretary has been so notified by

termination shall not prejudice any rights accruing hereunder prior to such
termination;

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

     (d)  The Indenture Trustee and each Obligee shall have failed to demand

and when each new issue of Obligations is executed, authenticated and delivered
on a date or dates subsequent to the date hereof, as contemplated by, and
pursuant to the Indenture, the Shipowner shall, at the time of the issuance of
such Obligations, execute and deliver to the Secretary an additional Secretary's
Note or, at the Secretary's discretion, an endorsement to the Secretary's Note
in an amount equal to the

                                       16
<Page>

principal amount of, and at the interest rate borne by, such issue of
Obligations, on the terms stated in the Secretary's Note.

     SECTION 4.01.  MONEYS DUE WITH RESPECT TO CONSTRUCTION OF THE VESSELS. (a)
In the event that the Shipowner shall receive any moneys from any Person in
connection with the Construction of any Vessel, the Shipowner shall give written

     (b)  Upon and after a final determination of Actual Cost in accordance with
Section 5.01, in the absence of a Default, any moneys held by the Depository

     (c)  In the event there is an existing Default, the money shall be held by

     (d)  In the event the Secretary assumes the Shipowner's rights and duties

                          ACTUAL COST; THE ESCROW FUND

     SECTION 5.01.  ACTUAL COST DETERMINATIONS. (a) The Actual Cost of each
Vessel (and the aggregate Actual Cost of all of the Vessels), determined as of
the date of this Security Agreement, is as set forth in Table A hereof.

     (b)  The Secretary agrees to: (1) make a final determination of the Actual
Cost of each Vessel, limited to amounts paid by or for the account of the
Shipowner on account of the items set forth in Table A hereof and, to the extent

Vessel, excluding any amounts which are not to become due and payable, and (2)
promptly give written notice to the Shipowner, of the results of said final
determination; PROVIDED THAT, the Shipowner shall have requested such
determination not less than 60 days in advance and shall have furnished to the

together with a breakdown of such totals according to the items for which paid
or obligated to be paid.

     SECTION 5.02.  ESCROW FUND DEPOSITS. At the time of the sale of the
Obligations, the Shipowner shall deposit with the Secretary in the Escrow Fund
all of the proceeds of that sale unless the Shipowner is entitled to withdraw

all of the Vessels, then the Shipowner shall also deposit into the Escrow Fund
on the Closing Date an amount equal to six months interest at the rate borne by
the Obligations.

     SECTION 5.03.  ESCROW FUND WITHDRAWALS. (a) The Secretary shall within a
reasonable time after written Request from the Shipowner, disburse from the
Escrow Fund directly to the Indenture Trustee, any Paying Agent for such
Obligations, the Shipyard, or any other Person entitled thereto, any amount
which the Shipowner is obligated to pay, or to the Shipowner for any amounts it
has paid, on account of the items and amounts or any other items set forth in
Table A annexed hereto or subsequently approved by the Secretary, PROVIDED THAT,
the Secretary is satisfied with the accuracy and completeness of the information
contained in the following submissions:

            (1) A Responsible Officer of the Shipowner shall deliver an
Officer's Certificate, in form and substance satisfactory to the Secretary,
stating that (A) there is neither a Default under the Construction Contract nor
the Security Agreement; (B) there have been no occurrences which have or would
adversely and materially affect the condition of the Vessel, its hull or any of
its component parts; (C) the amounts of the Request are in accordance with the
Construction Contract including the approved disbursement schedule and each item
in these amounts is properly included in the Secretary's approved estimate of
Actual Cost; (D) with respect to the Request, once the Contractor is paid there
will be no liens or encumbrances on the applicable Vessel, its hull or component
parts for which the withdrawal is being requested except for those already
approved by the Secretary; and (E)

                                       18
<Page>

if the Vessel has already been delivered, it is in class and is being maintained
in the highest and best condition. The Shipowner shall also attach an Officer's
Certificate of the Shipyard, in form and substance satisfactory to the
Secretary, stating that there are no liens or encumbrances as provided in clause
(D) of this subsection and attaching the invoices and receipts supporting each
proposed withdrawal to the satisfaction of the Secretary.

            (2) No payment or reimbursement under this Section shall be made (A)
to any Person until the total amount paid by or for the account of the Shipowner
from sources other than the proceeds of such Obligations equals at least 12-l/2%
of the Actual Cost of the related Vessel is made; (B) to the Shipowner which
would have the effect of reducing the total amounts paid by the Shipowner
pursuant to clause (A) of this subsection; or (C) to any Person on account of
items, amounts or increases representing changes and extras or owner furnished
equipment, if any, set forth in Table A annexed hereto, unless such items,
amounts and increases shall have been previously approved by the Secretary;
PROVIDED, HOWEVER, that when the amount guaranteed by the Secretary equals 75%
or less of the Actual Cost, then after the initial 12 1/2% of Actual Cost has
been paid by or on behalf of the Shipowner for such Vessel and up to 37 1/2% of
Actual Cost has been withdrawn from the Escrow Fund for such Vessel, the
Shipowner shall pay the remaining Shipowner's equity of at least 12 1/2% (as
determined by the Secretary) before additional monies can be withdrawn from the
Escrow Fund relating to such Vessel.

     (b)  The excess, as determined by the Secretary, of any amount on deposit
in the Escrow Fund which represents interest on the principal amount deposited,
over and above the amount of interest due on the next Interest Payment Date on
the principal amount, as determined by the Secretary, remaining on deposit on
such Interest Payment Date, may, unless there is an existing Default, be
disbursed by the Secretary upon the Shipowner's Request made not more than 10
Business Days prior to such Interest Payment Date or made within at least 60
days after such Interest Payment Date.

     (c)  The Secretary shall not be required to make any disbursement pursuant
to this Section except out of the cash available in the Escrow Fund. If
sufficient cash is not available to make the requested disbursement, additional
cash shall be provided by the maturity or sale of securities in accordance with
instructions pursuant to Section 5.04. If any sale or payment on maturity shall
result in a loss in the principal amount of the Escrow Fund invested in
securities so sold or matured, the requested disbursement from the Escrow Fund
shall be reduced by an amount equal to such loss, and the Shipowner shall, no
later than the time for such disbursement, pay to the Indenture Trustee, any
Paying Agent, the Shipyard, or any other Person entitled thereto, the balance of
the requested disbursement from the Shipowner's funds other than the proceeds of
such Obligations.

     (d)  If the Secretary assumes the Shipowner's rights and duties under the
Indenture and the Obligations, and makes any payments in default under the
Indenture, or the Secretary pays the Guarantees, all amounts in the Escrow Fund
(including realized income which has not yet been paid to the Shipowner), shall
be paid to the Secretary and be credited against any amounts due or to become
due to the Secretary under the Security Agreement and the Secretary's Note. To
the extent payment of the Escrow Fund to the Secretary is not required, said
amounts or any balance thereof, shall be paid to the Shipowner.

                                       19
<Page>

     (e)  At any time the Secretary shall have determined that there has been,
for any reason, a disbursement from the Escrow Fund contrary to this Section,
the Secretary shall give written notice to the Shipowner of the amount
improperly disbursed, the amount to be deposited or redeposited into the Escrow
Fund on account thereof, and the reasons for such determination. The Shipowner
shall thereafter promptly deposit or redeposit, as appropriate, such amount
(with interest, if any) required by the Secretary into the Escrow Fund.

     (f)  Notwithstanding any other provision of this Section, the Shipowner
shall not seek or receive reimbursement for any amount paid to the Shipyard or
any Person by the Secretary.

     (g)  In the event that one of the events described in Section 2.07 has
occurred with respect to one or more of the Vessels or the Secretary shall have
paid the Guarantees or shall have assumed the Shipowner's rights and duties
under Section 6.09 of the Indenture, the Secretary may direct that moneys
remaining on deposit in the Escrow Fund may be withdrawn in whole or in part for
one of the following purposes: (1) application as provided in Section 3.05 of
the Indenture (but in no event shall any such disbursement for such purpose be
in an amount greater than the related Proportionate Part of the Outstanding
Obligations); (2) payment to the Shipowner, or its order, in the event all
Outstanding Obligations are Retired or Paid, other than by payment of the
Guarantees; or (3) application as provided in Section 6.05, if the Secretary
shall have paid the Guarantees or shall have assumed the Shipowner's rights and
duties under the Indenture and the Obligations.

     (h)  Any amounts remaining in the Escrow Fund on the Termination Date of
the Escrow Fund which are in excess of 87 1/2% or 75% of Actual Cost, as the
case may be, shall be applied pursuant to Section 3.04 of the Indenture to
retire a Proportionate Part of the Outstanding Obligations.

     SECTION 5.04.  INVESTMENT AND LIQUIDATION OF THE ESCROW FUND. The Secretary
may invest the Escrow Fund in obligations of the United States with such
maturities that the Escrow Fund will be available as required for the purposes
hereof. The Secretary shall deposit the Escrow Fund into an account with the
Treasury Department and upon agreement with the Shipowner, shall deliver to the
Treasury Department instructions for the investment, reinvestment and
liquidation of the Escrow Fund. The Secretary shall have no liability to the
Shipowner for acting in accordance with such instructions.

     SECTION 5.05.  INCOME ON THE ESCROW FUND. Except as provided in Section
5.03, any income realized on the Escrow Fund shall, unless there is an existing
Default, be paid to the Shipowner upon receipt by the Secretary of such income.
For the purpose of this Section, the term "income realized on the Escrow Fund,"
shall mean with respect to the Escrow Fund (1) the excess of the cash received
from the sale of securities over their cost (less any losses from sale not
already paid pursuant to Section 5.03(c)) and (2) cash received from the payment
of principal and interest on securities.

     SECTION 5.06.  TERMINATION DATE OF THE ESCROW FUND. The Escrow Fund will
terminate 90 days after the Delivery Date of the last Vessel covered by this
Security Agreement (herein called the

                                       20
<Page>

"Termination Date of the Escrow Fund"). In the event that on such date the
payment by or for the account of the Shipowner of the full amount of the
aggregate Actual Cost of all of the Vessels set forth in Table A hereof has not
been made or the amounts with respect to such Actual Cost are not then due and
payable, then the Shipowner and the Secretary by written agreement shall extend
the Termination Date of the Escrow Fund for such period as shall be determined
by the Shipowner and the Secretary as sufficient to allow for such
contingencies. If the Secretary shall have earlier made a final determination of
the aggregate Actual Cost of all of the Vessels in accordance with Section 5.01,
the Termination Date of the Escrow Fund shall be deemed to be the date of such
final determination; PROVIDED THAT, if as a result of such final determination,
a redemption of Obligations is required pursuant to Section 3.04 of the
Indenture, the Termination Date shall be the date specified as the Redemption
Date in the notice of redemption given pursuant to Section 3.08 of the
Indenture.
