     the reasons  provided in Clause  28(a) of the Bareboat  Charter  and/or any
     other reason  attributable to the Sellers as charterers  under the Bareboat
     Charter,  then upon such termination taking place, the Purchase Price shall
     be  automatically  reduced by an amount  (such  amount  referred  to as the
     "Purchase Price Reduction  Amount") which is equal to the lesser of (i) the
     Seller's Credit and (ii) the total amount of hire that would have been paid
     to the New Buyers under the terms of the Bareboat  Charter had the Bareboat
     Charter  continued  uninterrupted for its full duration up to 14 March 2011
     and such  reduction  shall have as a result the  reduction  of the Sellers'
     Credit by an amount equal to the Purchase Price Reduction Amount.

     Buyers shall provide the Sellers with a second preferred  Mortgage over the
     Vessel,  being subordinate to a first preferred Mortgage over the Vessel in
     favour of Fortis Bank NV/SA, as more particularly described in the Bareboat
     Charter."

     provision of the Original  MOA shall be amended by this  Agreement  and the
     Original  MOA and  this  Agreement  shall  be  read  and  construed  as one
     instrument.

5    Conditions

     to the conditions precedent contained in schedule 1 being satisfied.

     different parties on separate counterparts,  each of which when so executed
