(LACP).

TERM: The initial term of this Agreement shall be from April 1, 1999 through
March 31, 2000, cad thereafter for successive one year terms unless and until
terminated by either party with thirty (30) days notice.

U.S. ENERGY SHALL:

1.       Provide a detailed economic comparison of receiving natural gas
         transportation service from a Local Distribution Company (LDC), or
         directly connecting with Northern Natural Gas (NNG). U.S. Energy will
         provide LACP with engineering cost estimates, route drawings, and a
         project timeline related to constructing pipeline facilities directly
         connecting LACP with NNG.

         In the event that the direct connect pipeline option is selected, U.S.
         Energy will submit the tap request Engineering and construction
         management services related to constructing to NNG can be provided by
         U.S. Energy Services on a fee basis.

2.       Determine whether firm, interruptible, or a blend of transportation
         entitlement with NNG will provide the lowest burnertip cost for LACP.
         Factors that will be considered include NNG credits for the new
         interconnect, cost of an alternate fuel system, and availability of
         specific receipt point capacity. Analysis of the costs and benefits
         will require U.S. Energy to negotiate as LACP's agent with NNG and
         other potential third party shippers.

3.       Provide natural gas supply information to minimize the cost of natural
         gas purchased by LACP. This will include acquiring multiple supply
         quotes and reporting to LACP the various supply index and fixed prices.
         U.S. Energy will not take title to LACP gas supplies, but will
         communicate supply prices and potential buying strategies.

4.       Negotiate directly with NNG, other shippers, and suppliers to provide
         transportation, balancing, and supply agreements that meet LACP's
         performance criteria at the lowest possible cost.

5.       Provide daily nominations to NNG, other applicable shippers, and
         suppliers for LACP. This will include daily written confirmations to
         LACP of all nominations and actual daily usage. U.S. Energy will

                           on-site generation.

                  e.       Negotiation of electric service agreements that meet
