net revenue  interest  and not greater  than the working  interest in the Assets

purchaser of such.

               (ii) The  amount of all costs and  expenses,  including,  without
limitation,  royalties,  rentals and other charges, ad valorem, windfall profit,
and other  taxes  based upon or  measured  by the  ownership  of property or the
production of hydrocarbons or the receipt of proceeds  therefrom,  expenses paid
under  applicable  operating  agreements  and,  in the  absence of an  operating
agreement,  expenses of the sort customarily  billed under such agreements,  not
including income taxes,  paid by or on behalf of Seller,  in connection with the
operation of the Assets during the period after the Effective Date.

               (iii) An amount equal to all prepaid expenses attributable to the
Assets  that are paid by or on behalf of Seller  prior to the  Closing  Date and
that  are,  in  accordance  with  generally  accepted   accounting   principles,
attributable  to  the  period  after  the  Effective  Date,  including,  without
limitation,  prepaid ad valorem,  property,  production,  severance, and similar
taxes (but not  including  income taxes) based upon or measured by the ownership

limitation,   royalties,  rentals  and  other  charges,  ad  valorem,  property,
production,  excise,  severance,  windfall profit, and other taxes based upon or
measured by the ownership of property or the production of  hydrocarbons  or the
receipt  of  proceeds  therefrom,   expenses  paid  under  applicable  operating
agreements and, in the absence of an operating  agreement,  expenses of the sort
customarily billed under such agreements, not including income taxes, paid by or
on behalf of Buyer,  in  connection  with the operation of the Assets during the
period prior to the Effective Date.

               (iii) Any  unpaid  amount  attributable  to any  reduction  under
Article IV for a Casualty Loss which occurs prior to the Effective Date.

          (c) In addition to the matters  mentioned  above, the final Settlement
Statement  shall  include any other debits and credits,  either cash or accrued,
but  excluding  income and  franchise  taxes,  which  under  generally  accepted
accounting  principles  would reflect transfer of ownership of the Assets on the
Effective Date.

          (d) The net amount to be paid by the owing  party shall be paid thirty
(30) days after  receipt of a Settlement  Statement.  Buyer shall have the right
for a period of one (1) year from the date of the final Settlement  Statement in
