        WHEREAS,
Executive is presently the Vice President—Chartering of the Company, United States Shipping Master LLC, a Delaware limited liability company
("Parent"), and each subsidiary of Parent (collectively with the Company, Parent and any entity that hereafter becomes a subsidiary of Parent or U.S.

        WHEREAS,
the Company and Executive are parties to an employment agreement dated as of September 13, 2002 (the "Prior Agreement"); 


        WHEREAS,
the Company and Executive desire to amend and restate the terms of the Prior Agreement; and

this Agreement shall supercede and completely replace the Prior Agreement as of the Effective Date. 



        NOW,
THEREFORE, in consideration of the premises and of the mutual promises, representations and covenants herein contained, the parties hereto agree as follows: 


        1.    EMPLOYMENT.



        The
Company hereby employs Executive and Executive hereby accepts such employment, subject to the terms and conditions herein set forth. Executive shall hold the office of Vice
President—Chartering of the Company reporting to the President of the Company.

        3.    COMPENSATION.



        As
compensation for the employment services to be rendered by Executive hereunder, including all services as an officer or director of any member of the US Shipping Group, the Company
agrees to pay, or cause to be paid, to Executive, and Executive agrees to accept, payable in equal installments in 







 



accordance
with Company practice, an initial annual salary of $257,000. Executive's annual salary hereunder for the remaining years of employment shall be determined by the Board of Directors of the
General Partner (the "GP Board") in its sole discretion; provided, however, that in no event shall Executive's salary in any year be reduced below the
rate for the previous year. In addition, Executive shall be eligible for bonuses from time to time in such amounts as may be determined by the GP Board in its sole discretion. 


        4.    EXPENSES.



        The
Company shall pay or reimburse Executive, upon presentment of suitable vouchers, for all reasonable business and travel expenses which may be incurred or paid by Executive in
connection with his employment hereunder in accordance with Company policy as established from time to time by the Board of Directors. Executive shall comply with such restrictions and shall keep such
records as the Company may reasonably deem necessary to meet the requirements of the Internal Revenue Code of 1986, as amended from time to time (the
"Code"), and regulations promulgated thereunder. 


        5.    OTHER
BENEFITS. 


        Executive
shall be entitled to five weeks paid vacation per year and to participate in such benefit plans and arrangements and receive any other benefits customarily provided by the
Company to its senior management personnel (including any profit sharing, pension, short- and long-term disability insurance, hospital, major medical insurance and group life insurance
plans in accordance with the terms of such plans) and including stock option and/or stock purchase plans, all as determined from time to time by the GP Board, on a level commensurate with Executive's
seniority (the "Benefit Plans"). The Company shall indemnify Executive to the fullest extent permitted by Delaware law, including the advancement of
legal expenses and costs. 


        6.    DUTIES.

Officer, the Board of Directors of the Company (the "Company Board") and the GP Board, and be subject to the direction of the Chief Executive Officer,

        (b)
During the Employment Term, Executive shall devote a majority of his time and attention, reasonable vacation time and absences for sickness excepted, to the business of the Company,
as necessary to fulfill his duties. Executive shall perform the duties assigned to him with fidelity and to the best of his ability. Notwithstanding anything herein to the contrary, Executive may
engage in other activities so long as such activities do not unreasonably interfere with Executive's performance of his duties hereunder and do not violate Section 9 hereof. The Company
recognizes that Executive will be devoting a significant minority of his time to the activities set forth on Schedule A attached hereto and will be compensated independently for same. 


        (c)
Nothing contained in this Section 6 or elsewhere in this Agreement shall be construed to prevent Executive from investing or trading in non-competing investments
as he sees fit for his own account, including real estate, stocks, bonds, securities, commodities or other forms of investments. Specifically, the Company acknowledges that (i) the Executive
has disclosed ownership interests in and management responsibilities for the entities and assets listed on Schedule A attached hereto and (ii) neither such ownership interests nor
management responsibilities as they exist as of the date hereof

or corporation other than the members of the US Shipping Group and their respective directors, managers, officers and employees, of any confidential information or trade secret of the US Shipping

any amounts or benefits hereunder other than such portion of Executive's annual salary and reimbursement of expenses pursuant to Section 4 hereof as has been accrued through the date of his
termination of employment. 




        (c)
If Executive should die during the term of his employment hereunder, this Agreement shall terminate immediately. In such event, the estate of Executive shall thereupon be entitled to
receive such portion of Executive's annual salary and reimbursement of expenses pursuant to Section 4 as has been accrued through the date of his death. Executive shall also be entitled to any
amounts or benefits payable under the terms of the Benefit Plans. 


        (d)
Upon a finding by the GP Board of Executive's disability in accordance with Section 7(b) hereof, the Company shall have the right to terminate Executive's employment.
Notwithstanding any inability to perform his duties, Executive shall be entitled to receive his compensation (including bonus, if any) pursuant to Section 3 and reimbursement of expenses
pursuant to Section 4 as provided herein until he begins to receive long-term disability insurance benefits under the policy provided by the Company pursuant to Section 5
hereof. In the event that payments received from such long-term disability insurance policy do not equal the Executive's rate of salary at the time of the disability, then for a period of
12 months following termination the Company shall continue to pay to Executive the difference between the policy benefit and such rate of salary, subject to any applicable tax withholding. Any
termination pursuant to this subsection (e) shall be effective on the later of (i) the date 30 days after which Executive shall have received written notice of the Company's

        (e)
Notwithstanding any provision to the contrary contained herein, in the event that Executive's employment is terminated by the Company without justifiable cause or by the Executive
for good reason, the Company shall (i) pay Executive, for a period of two years following the date of termination (such period being hereinafter referred to as the
"Severance Period"), a monthly payment (subject to applicable tax withholding) equal to one-twelfth of his then annual salary and
one-twelfth of his target bonus for the year in which termination of employment occurs, as established by the compensation committee of the GP Board (provided that if the compensation
committee has not established a target bonus for such year, then for purposes of this Section 7(e) such target bonus shall be 50% of Executive's then current salary), which amount shall be in
lieu of any and all other payments due and owing to Executive under the terms of this Agreement (other than any payments constituting reimbursement of expenses pursuant to Section 4 hereof and
any payments or benefits payable under the Benefit Plans), and (ii) continue to allow Executive to participate, at the Company's expense (to the same extent the Company bears such expense at
the time of termination), in the Company's health insurance program, to the extent permitted under such programs, until the earlier of (1) the end of the Severance Period or (2) the date
Executive begins employment with another entity which provides substantially similar benefits to the Executive (collectively, the "Severance Payments");
provided, however, that the Company's obligation to make the Severance Payments shall be conditional upon Executive executing a general release in favor of the Company and Executive's compliance with
his obligations under Sections 9, 10, 11 and 12 hereof; and provided further, that in the event that Executive's employment is terminated by the Company without justifiable cause (including by reason
of non-renewal of this Agreement) or by the Executive for good reason within two years following the effective date of a change of control, then the Company shall pay to Executive, in lieu
of the amounts to be paid pursuant to clause (i) of the first sentence of this Section 7(e), an amount equal to the product determined by multiplying (x) the sum of his then
annual salary and his target bonus for the year in which termination of employment occurs, as established by the compensation committee of the GP Board (provided that if the compensation committee has
not established a target bonus for such year, then for purposes of this Section 7(e) such target bonus shall be 50% of Executive's then current salary), by (y) three, such payment to be
made within ten business days following such termination of employment. If Executive's employment is terminated by the Company without justifiable cause (including by reason of non-renewal
of this Agreement) or by the Executive for good reason at a time when the Partnership, the General Partner or Parent is in negotiations regarding a transaction that would, if consummated, constitute a
change of
control and such transaction is consummated within one year following Executive's termination of employment, then Executive's severance shall be calculated and paid as if such termination had occurred
within two years following a change of control, and the Company shall, upon consummation of such transaction, pay to Executive an amount equal to the difference between the amount he would be entitled
to pursuant to this sentence and the amount of severance payments Executive has received through such date. 


        (f)
Upon Executive's termination of his employment hereunder or his election not to renew this Agreement, this Agreement (other than Sections 5, 9, 10, 11, 12 and 15 which shall survive
in accordance with their terms) shall terminate. In such event, Executive shall be entitled to receive such portion of Executive's annual salary and bonus, if any, as has been accrued to date.
Executive shall be entitled to reimbursement of expenses pursuant to Section 4 hereof and to continue to participate in the Benefit Plans to the extent participation by former employees is
required by law or permitted by such plans, with the expense of such participation to be as specified in such plans for former employees. Executive shall also be entitled to any amounts or benefits
payable under the terms of the Benefit Plans. 


        8.    REPRESENTATIONS
AND AGREEMENTS OF EXECUTIVE. 


        (a)
Executive represents and warrants that he is free to enter into this Agreement and to perform the duties required hereunder, and that there are no employment contracts or
understandings, 


5







 



restrictive
covenants or other restrictions, whether written or oral, preventing the performance of his duties hereunder. 


        (b)
Executive agrees to submit to a medical examination and to cooperate and supply such other information and documents as may be reasonably required by any insurance company in
connection with the Company's obtaining life insurance on the life of Executive, and any other type of insurance or fringe benefit as the Company shall determine from time to time to obtain. 


        9.    NON-COMPETITION.



        (a)
In view of the unique and valuable services expected to be rendered by Executive to the US Shipping Group, Executive's knowledge of the trade secrets and other proprietary
information relating to the business and in consideration of the compensation to be received hereunder and Executive's direct ownership interest in the Parent and indirect ownership in the
Partnership, Executive agrees that during his employment by the Company and, following the termination of Executive's employment hereunder, during the Non-Competition Period (as defined
below), Executive shall not,
directly or indirectly, as owner, partner, joint venturer, stockholder, employee, broker, agent, principal, trustee, corporate officer, director, licensor, or in any capacity whatsoever engage in,
become financially interested in, be employed by, render any consultation or business advice with respect to, or have any connection with, (i) any business which is competitive with products or
services of the US Shipping Group in the United States of America or (ii) any business conducted under any corporate or trade name utilized by the US Shipping Group or any name similar thereto
without the prior written consent of the Company; provided, however, that Executive may own any securities of any corporation which is engaged in such business and is publicly owned and traded but in
an amount not to exceed at any one time one percent (1%) of any class of stock or securities of such corporation. The Company hereby agrees that the following activities shall not be deemed to be a
business competitive with the business of the US Shipping Group: 



        (i)
employment by any entity that is not engaged in the ownership and operation of vessels engaged in the coastwise trade under the Jones Act; 


        (ii)
employment by an entity that has divisions or affiliates engaged in the ownership and operation of vessels engaged in the coastwise trade under the Jones Act as long as Executive is
employed in a division or affiliate of such entity that does not, directly or indirectly, engage in the ownership and operation of vessels engaged in the coastwise trade under the Jones Act and
Executive does not share information, directly or indirectly, with those divisions and/or affiliates of such entity engaged in the ownership and operation of vessels engaged in the coastwise trade
under the Jones Act; 


        (iii)
transportation of chemical products on the tank barges listed on Schedule A hereto and, subject to the provisions of Section 9(b) below, any other tank barges of less
than 15,000 tons deadweight, other than the transportation of petroleum or petroleum products, as long as either (i) Mr. Miller continues to engage in such business on a continuous basis
after the date hereof or (ii) if Mr. Miller does not continue to engage in such business on a continuous basis after the date hereof, at the time Mr. Miller determines to reenter
such business, the US Shipping Group is not then engaged in such business. 




In
addition, Executive shall not, directly or indirectly, during the Non-Competition Period, request or cause any suppliers or customers with whom the US Shipping Group has a business
relationship to cancel or terminate any such business relationship with any member of the US Shipping Group or solicit, interfere with or entice from the Parent or any of its subsidiaries any employee
(or former employee) of the Parent or any of its subsidiaries. For purposes hereof, the "Non-Competition Period" shall mean: (i) if
Executive's employment is terminated by the Company for justifiable cause (as defined in Section 7(b)) or disability (as defined in Section 7(b)), or if Executive voluntarily terminates 


6







 

his
employment hereunder (including by electing not to renew this Agreement), a period of two (2) years following such termination of employment; and (ii) if Executive's employment is
terminated by the Company for other than justifiable cause or disability, by the Executive for good reason, or as a result of the Company's election not to renew the employment agreement, the
Severance Period, provided, however, that in the case of this clause (ii) if the Company breaches its obligation to make the Severance Payments or to comply with its obligations under
Section 4 hereof, and such breach is not cured within thirty (30) days after written notice of such breach is provided to the Company by Executive, Executive shall be released from his
obligations under this Section 9. 


        (b)
Notwithstanding Section 9(a) hereof, Executive agrees that during his employment by the Company he will not, directly or indirectly, acquire an interest in any tank barge
(other than those listed on Schedule A hereto) of less than 15,000 deadweight tons if at any time more than 50% of the annual revenue expected to be generated from the operation of such tank
barge is expected to be "qualifying income" (within the meaning of Section 7704(d) of the Code, or any successor provision thereto) without first offering to the Partnership the opportunity to
acquire such interest on the same terms and conditions offered to him and the conflicts committee of the GP Board determining that the Partnership is not interested in acquiring such interest;
provided that if at the time of acquisition less than 50% of the annual revenue expected to be generated from the operation of such tank barge is expected to be "qualifying income" and therefore was
not offered to the Partnership, but subsequently 50% or more of the annual revenue expected to be generated from the operation of such tank barge is expected to be "qualifying income," then at such
time Executive shall offer to the conflicts committee of the GP Board the right to have the Partnership acquire such tank barge (or Executive's interest therein) at fair market value. 



        (c)
If any portion of the restrictions set forth in this Section 9 should, for any reason whatsoever, be declared invalid by a court of competent jurisdiction, the validity or
enforceability of the remainder of such restrictions shall not thereby be adversely affected. 


        (d)
Executive acknowledges that the Parent has invested substantial monies in connection with the acquisition of the Business (as defined in the Asset Purchase Agreement, dated as of
July 18, 2002, among Amerada Hess Corporation, United States Shipping LLC (f/k/a US Shipping Acquisition LLC), a subsidiary of Parent, the Company and the other signatories thereto (the
"Purchase Agreement")) from Hess and that the provisions of this Section 9 were a material inducement to the US Shipping Group to consummate the
transactions contemplated by the Purchase Agreement (the "Acquisition"), and that the US Shipping Group would not have consummated the Acquisition but
for the agreements
and covenants contained herein. Executive further acknowledges that the territorial and time limitations set forth in this Section 9 are reasonable and properly required for the adequate
protection of the business of the US Shipping Group. Executive hereby waives, to the extent permitted by law, any and all right to contest the validity of this Section 9 on the ground of
breadth of its geographic or product and service coverage or length of term. In the event any such territorial or time limitation is deemed to be unreasonable by a court of competent jurisdiction,
Executive agrees to the reduction of the territorial or time limitation to the area or period which such court shall deem reasonable. 



        (e)
The existence of any claim or cause of action by Executive against the Company or any other member of the US Shipping Group shall not constitute a defense to the enforcement by the
US Shipping Group of the foregoing restrictive covenants, but such claim or cause of action shall be litigated separately. 


        10.    INVENTIONS
AND DISCOVERIES. 


        (a)
Executive shall promptly and fully disclose to the Company, with all necessary detail for a complete understanding of the same, all developments, know-how, discoveries,
inventions, improvements, concepts, ideas, writings, formulae, processes and methods (whether copyrightable, patentable or otherwise) made, received, conceived, developed, acquired or written during
working 


7







 



hours,
or otherwise, by Executive (whether or not at the request or upon the suggestion of the Company) during the period of his employment with the Company, solely or jointly with others, using the
US Shipping Group's resources, or relating to any current or proposed business or activities of the US Shipping Group known to him as a consequence of his employment or the rendering of advisory and
consulting services hereunder (collectively, the "Subject Matter"). 


        (b)
Executive hereby assigns and transfers, and agrees to assign and transfer, to the Company all his rights, title and interest in and to the Subject Matter, and Executive further
agrees to deliver to the Company any and all drawings, notes, specifications and data relating to the Subject Matter, and to execute, acknowledge and deliver all such further papers, including
applications for trademarks, copyrights or patents, as may be necessary to obtain trademarks, copyrights and patents for any thereof in any and all countries and to vest title thereto in the Company.
Executive shall assist the Company in obtaining such trademarks, copyrights or patents during the term of this Agreement, and any time thereafter on reasonable notice and at mutually convenient times,
and Executive agrees to testify in any prosecution or litigation involving any of the Subject Matter; provided, however, that following termination of employment Executive shall be reasonably
compensated for his time and reimbursed his reasonable out-of-pocket expenses incurred in rendering such assistance or giving or preparing to give such testimony if it is
required after the Non-Competition Period. 


        11.    NON-DISCLOSURE
OF CONFIDENTIAL INFORMATION. 


        (a)
Executive shall not, during the term of this Agreement, or at any time following expiration or termination of this Agreement, directly or indirectly, disclose or permit to be known
(other than as is required in the regular course of his duties (including without limitation disclosures to the Company's advisors and consultants) or as is required by law (in which case Executive
shall give the Company prior written notice of such required disclosure) or with the prior written consent of the Company's Chief Executive Officer), to any person, firm or corporation, any
confidential information acquired by him during the course of, or as an incident to, his employment hereunder, relating to the US Shipping Group, any client of the US Shipping Group, or any
corporation, partnership or other entity owned or controlled, directly or indirectly, by any of the foregoing, or in which any of the foregoing has a beneficial interest, including, but not limited
to, the business affairs of each of the foregoing. Such confidential information shall include, but shall not be limited to, proprietary technology, trade secrets, patented processes, research and
development data, know-how, market studies and forecasts, competitive analyses, pricing policies, employee lists, personnel policies, the substance of agreements with customers, suppliers
and others, marketing or dealership arrangements, servicing and training programs and arrangements, customer lists and any other documents embodying such confidential information. This confidentiality
obligation shall not apply to any confidential information which is known to Executive as a result of his professional business experience prior to the date hereof or his involvement in the business
activities set forth on Schedule A hereof or which becomes publicly available from sources unrelated to the US Shipping Group. 


        (b)
All information and documents relating to the US Shipping Group as hereinabove described (or other business affairs) shall be the exclusive property of the Company, and Executive
shall use commercially reasonable best efforts to prevent any publication or disclosure thereof. Upon termination of Executive's employment with the Company, all documents, records, reports, writings
and other similar documents containing confidential information, including copies thereof, then in Executive's possession or control shall be returned and left with the Company.

PERFORMANCE. 


        Executive
agrees that if he breaches, or threatens to commit a breach of, any of the provisions of Sections 9, 10 or 11 (the "Restrictive
Covenants"), the Company shall have, in addition to, and not in lieu of, any other rights and remedies available to the Company under law and in equity, the right to injunctive
relief and/or to have the Restrictive Covenants specifically enforced by a court of competent 


8







 



jurisdiction,
without the posting of any bond or other security, it being agreed that any breach or threatened breach of the Restrictive Covenants would cause irreparable injury to the US Shipping
Group and that money damages would not provide an adequate remedy to the Company. Notwithstanding the foregoing, nothing herein shall constitute a waiver by Executive of his right to contest whether a
breach or threatened breach of any Restrictive Covenant has occurred. 


        13.    AMENDMENT
OR ALTERATION. 


        No
amendment or alteration of the terms of this Agreement shall be valid unless made in writing and signed by both of the parties hereto.

therein.

controversy or claim arising out of or relating to this Agreement, or the breach thereof, shall be settled by arbitration in New York City by one (1) arbitrator in accordance
with the Commercial Arbitration Rules of the American Arbitration Association, and judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction thereof. Each
party shall bear its own costs (including legal fees and expenses) in the arbitration unless the arbitrator determines otherwise. Nothing in this paragraph shall preclude any party from seeking a
preliminary injunction or other provisional relief, either prior to, during or after invoking the procedures in this paragraph, if in its judgment such action is necessary to avoid irreparable damage
