          approval.  Upon an Empire conversion request, Conoco will offer a
          quote based on current market conditions and the following formulae:

          Mt. Vernon
          Conversion Dates                   Conway current spot plus

          January 21 - April 30, 1992             6.00 CPG
          May 1      - July  31, 1992             5.75 CPG
          August 1   - October 31, 1992           5.50 CPG

          Belle and Wood River will be billed on the above schedule plus 0.50
          CPG.

          Empire reserves the right to pull up to 45% of the converted volumes
          at the Belle terminal.  Empire may pull greater than 45% of the
          converted volumes at the Belle terminal upon written authorization
          from Conoco Propane Marketing.  No limitations apply to the proportion
          of converted volumes which Empire may pull at Mt. Vernon and Wood
          River.

          No vintaging of conversion volumes will occur.  Instead, a new
          weighted average conversion price will be calculated as additional
          volumes are converted.

          The down payment of 5.00 CPG will be due net within ten days from date
          of invoice.  The balance will be invoiced in accordance with the above
          schedule as the product is delivered to Empire, but in no event later
          than March 31, 1993.  The balance due invoices will be subject to
          1.00% 10 days/Net 11 days from date of invoice.

          This section shall be updated in 1993, prior to converting volumes for
          the 1993/1994 heating season.

          PRICE:  Contract amended effective 4/1/91 until the end of the
          contract term  -- price shall be Conoco's established price on the
          date of delivery less 0.700 cents per gallon.  This reduction shall
          only apply to purchases on Conoco's established posting.
