                      AGREEMENT AND CONSENT TO ASSIGNMENT
 
                             TO: PALM SHIPPING INC.
    

                                  LUZON SPIRIT
 
      We refer to the time charter party dated May 1, 1992, as amended, made
between us, Nassau Spirit Inc., and you, Palm Shipping Inc., by which we agreed
to let and you agreed to take on time charter for the period and on the terms
and conditions set out in the Charter of the LUZON SPIRIT of about 28,742 net
tons and 57,448 gross tons registered in our name under the Bahamian flag.
 
    

     We hereby give you notice of the following, and you by your execution and
delivery of this Agreement and Consent to Assignment hereby agree to the
following:
 
     1. By an assignment (the "Assignment", the defined terms therein being
        used herein as therein defined) dated the date hereof (a copy of which
        is attached hereto) made between us and the Trustee referred to therein,
        we have sold, assigned, transferred and set over unto the Trustee all
        our right, title and interest in and to the Charter (as such term is
        defined in the attached Assignment) and in and to certain moneys and
        claims for moneys due and to become due to us (all as more fully
        described in the Assignment).
 
     2. You are hereby irrevocably authorized and instructed to pay, and agree
        that you will make payment of, all such moneys payable by you under the
        Charter to such place as the Trustee may from time to time direct.
 
     3. We shall remain liable to perform all our obligations under the Charter
        and the Trustee shall not be under any obligation under the Charter, but
        should the Trustee exercise its right to perform, or cause performance
        by its designee of, our obligations under the Charter, you agree,
        without thereby releasing us from our obligations under the Charter, to
        accept such performance.
 
     4. By your acknowledgement below, you agree that your obligation to make
        payment of all moneys payable by you under the Charter to the Trustee
        pursuant to paragraph 2 above is absolute and unconditional and shall
        not be affected by any circumstance, including, without limitation, (i)
        any set-off, counterclaim, recoupment, defense or other right against
        us, the Company, the Trustee or any Holder (as defined in the Indenture
        referred to in the Assignment) or anyone else for any reason whatsoever
        (whether in connection with the Vessel or otherwise), including, without
   8
 
        limitation, any defect in the title, condition, design, operation, or
        fitness for use of, or any damage to or loss or destruction of, or any
        lien, security interest or other charge or encumbrance upon, the Vessel
        or any part thereof or any interruption or cessation in the use or
        possession thereof by us or you or any subcharterer thereof for any
        reason, (ii) any insolvency, bankruptcy, reorganization or similar
        proceeding by or against the Company, us, the Trustee or any Holder or
        anyone else, (iii) any liability, obligation, claim, damage, penalty,
        cost or expense (including, without limitation, fees and expenses of
        attorneys, consultants, engineers and appraisers and any claim arising
        under any law, rule, regulation, charter, lease, permit, license or
        other requirement relating to pollution or to the protection of health
        or the environment) which may be imposed upon or incurred by or asserted
        against you or us or the Company, the Trustee, any Holder or anyone else
        for any reason or (iv) any other circumstance, happening or event
        whatsoever, whether foreseen or unforeseen and whether or not similar to
        any of the foregoing. If for any reason whatsoever, the Charter shall be
        terminated as to any vessel subject thereto by operation of law or
        otherwise, you nonetheless agree to pay to the Trustee all amounts
        payable under such Charter at the time such payments would have become
        due and payable in accordance with the terms of the Charter had such
        Charter not been so terminated. You hereby waive, to the extent
        permitted by applicable law, any and all rights which you may now have
        or which at any time hereafter may be conferred upon you, by statute or
        otherwise, to terminate, cancel, quit or surrender any Charter unless
        (a) the Securities shall have been paid in full and all sums payable to
        the Trustee under the Indenture shall have been paid in full or (b) the
        Termination and Release shall have occurred.
 
     5. You agree that the Trustee shall be entitled to exercise any and all
        rights and remedies of the Assignor under the Charter in accordance with
        the terms of the Assignment and the Indenture, and you shall comply in
        all respects with such exercise. You agree that the Charter, including,
        without limitation, all of your liens thereunder, shall be subordinated
        in all respects to the lien of the First Preferred Ship Mortgage in
        favor of the Trustee on the Vessel, and, at the option of the Trustee,
        foreclosure under such First Preferred Ship Mortgage shall terminate
        such Charter and such liens and divest you and your subcharterers of all
        right, title and interest in and to the Vessel. You agree that each
        subcharter of the Vessel shall be subordinate in all respects to the
        lien of such First Preferred Ship Mortgage.
 
                                        2

     6. You and we are each subsidiaries of the Company. Each present and
        future Guarantor (as defined in the Indenture) will assign its rights
        under a Charter (as defined in the Indenture and including but not
        limited to the Charter referred to in the Assignment) to the Trustee as
        security for, among other obligations, the Company's obligations under
        the Indenture and the Securities (as defined in the Indenture).
 
     7. Your obligations to pay hire under the Charter referred to in the
        Assignment include, without limitation, the obligation to pay hire
        thereunder so that each installment of hire thereunder shall be, under
        any circumstances and in any event, in an amount and paid on such date
        as shall be sufficient, when combined with all payments made on or
        before such date by you to the Trustee under all of the Charters (as
        defined in the Indenture) assigned to the Trustee, so that the Trustee
        shall have been paid in full as of its due date each payment of
        principal of and interest (and premium, if any) on the Securities (as
        defined in the Indenture) required to be paid by the Company pursuant to
        the Indenture on such due date.
 
     8. You hereby agree that, so long as any Securities (as defined in the
        Indenture) shall be outstanding and the Termination and Release shall
        not have occurred:
 
        (a) If an Event of Default (as defined in the Indenture) has occurred
            and is continuing and the Trustee has given you written notice
            thereof and requested that you issue instructions to the charterers
            and other obligors directly (and without derogation of any other
            rights of the Trustee), you shall specifically authorize and direct
            each charterer or other obligor to make payment of all the freights,
            hire and other moneys assigned pursuant to the Assignment of
            Freights and Hires (as defined in the Indenture) directly to our
            Cash Collateral Account (as defined in the Indenture) in accordance
            with our Cash Collateral Account Agreement (as defined in the
            Indenture), and shall obtain and deliver to the Trustee the written
            acknowledgment of each such charterer or other obligor of such
            instructions.
 
        (b) Upon the request of the Trustee from time to time, you shall
            provide to the Trustee such information as the Trustee may
            reasonably request regarding the Vessel and its use, including but
            not limited to the terms of each subcharter thereof, the subcharter
            party, the routes

            departure from each port on such route.
 
        (c) You covenant and agree with the Trustee that you will (i) duly
            perform and observe all of the terms and provisions of any charter
            or contract of affreightment on your part to be performed or
            observed; and (ii) clearly record on your books and records
            notations of the Assignment and the Assignment of Freights and Hires
            (as defined in the Indenture).
 
        (d) At any time and from time to time, upon the written request of the
            Trustee, you shall promptly and duly execute and deliver any and all
            such further instruments and documents as the Trustee may reasonably
            request in order to obtain the full benefits of the Assignment and
            of the rights and powers herein granted.

        (e) Whenever requested by the Trustee, you shall deliver letters to 
            each of your agents and representatives into whose hands or 
            control may come any earnings, moneys and property assigned by the 
            Assignment or assigned pursuant to the Assignment of Freights and 
            Hires, informing each such addressee of such assignments and, if 
            any Event of Default has occurred, instructing such addressee to 
            remit or deliver promptly to the Trustee all earnings, moneys and p
            property hereby assigned which may come into the addressee's hands 
            or control and to continue to make such remittances or delivery 
            until such time as the addressee may receive written notice or 
            instructions to the contrary direct from the Trustee. Each such 
            addressee shall acknowledge directly to the Trustee receipt of 
            your letter of notification and instructions.
 
     9.  Your acknowledgement and consent hereunder, and your agreements herein
         contained, are for the benefit of the Trustee and the Holders and shall
         be enforceable by the Trustee for its benefit and the benefit of the
         Holders.

         no further force and effect, upon (i) the payment in full of all of 
         the Obligations and the performance and observance of all agreements,
