AGREEMENT AMONG INITIAL STOCKHOLDERS AND MAC INC.

                    THIS AGREEMENT, dated November 3, 1995, is made
          and entered into among Empire Gas Corporation, a Missouri
          corporation ("Empire"), Northwestern Public Service
          Corporation, a Delaware ("NWPS"), and Myers Acquisition
          Company, a Delaware corporation ("MAC"), with respect to
          the following facts:

                    A.   Empire currently is engaged in the
          business of distributing and selling at retail liquefied
          petroleum ("LP") gas and appliances, and has a management
          experienced in the operation of such business.

                    B.   Northwestern Public Service Company
          ("NWPS") has as one of its objectives the making of
          investments that could benefit NWPS and its stockholders.

                    C.   Empire and NWPS, acting together, have
          made a successful bid to acquire the LP gas distribution
          and appliance business of Myers Propane Gas Company
          ("Myers"- such acquisition being hereinafter called the
          "Myers Acquisition").  Empire and NWPS have contemplated,
          in their bidding for the Myers Acquisition, that they
          will rely principally on Empire for management expertise
          and on NWPS to provide or arrange the financing for the
          Myers Acquisition, and that the success of the Myers
          Acquisition will depend in part upon the cost savings and
          operating improvements expected to be achieved by having
          Empire do the planning and management of the business of
          Myers and its subsidiaries, under the direction of the
          Board of Directors of MAC.

                    D.   Empire and NWPS have caused MAC to be
          incorporated to serve as the vehicle for making the Myers
          Acquisition.

                    E.   Empire and NWPS, on behalf of MAC, are
          concluding the negotiation of the definitive agreement
          (the "Myers Agreement of Merger") for the Myers
          Acquisition, and need to provide for (i) the initial
          capitalization of MAC, (ii) the management of MAC and
          (iii) for certain matters pertaining to the ownership of
          shares of stock of MAC.
