     or by the Owner Participant or the Owner Trust, as the case may be, to the

     amount, value or period.  If required by the terms of the applicable
     Operative Documents, such parties shall first attempt to agree on such
     matter.  If such parties are unable to agree on such matter within the time
     period specified in the applicable Operative Document, or if such parties
     are not required to attempt to agree, such parties shall thereupon consult
     for the purpose of selecting a mutually acceptable Independent appraiser.
     If within 10 days from the date the parties are required to so consult,
     they are unable to agree upon the appointment of a mutually acceptable
     Independent appraiser, then each of such parties shall appoint an
     Independent appraiser, and such Independent appraisers shall jointly
     determine such matter.  If one party does not so appoint an Independent
     appraiser, then the Independent appraiser appointed by the other shall
     determine such matter as the sole appraiser.  If such two Independent
     appraisers cannot agree on such matter within 20 days, such matters shall
     be determined by such two Independent appraisers and a third Independent
     appraiser chosen within 10 days after such 20-day period by such two
     Independent appraisers or, if such three Independent appraisers fail to
     reach an agreement, the determination of the appraiser that differs most
     from the second highest determination shall be excluded (unless such
     difference is less than ten percent from either of the other
     determinations), the remaining two determinations shall be averaged (or all
     three shall be averaged, if the third determination is not discarded due to
     the preceding parenthetical) and such average shall constitute the
     determination of the appraisers.  If such two Independent appraisers fail
     to agree upon the appointment of a third Independent appraiser within the
     allotted time period, such appointment shall be made by the New York City
     office of the American Arbitration Association or any organization
     successor thereto, upon the request of any such parties from a panel of
     arbitrators having  familiarity with assets similar to the Vessel.  The
     determination of the appraisers so chosen shall be given

                                       4
