GENERAL TERMS AND CONDITIONS
                                  (Continued)
   
                        Customer may use an agent to provide all or a
                        portion of its nomination data, provided that
                        Seller is so advised in advance in writing.  A
                        Customer that uses an agent for such nomination
                        purposes shall hold Seller harmless for all
                        actions or inactions of its agent.
   
                  (b)   Standard Nominations.  A "Standard Nomination" is
                        a nomination for Storage Service for any Day.  The
                        Standard Nomination shall include a begin date and
                        end date, which must be within the term of the
                        Customer's Service Agreement.  Each Day within a
                        date range nomination is considered an original
                        nomination.  Subsequent nominations for one or
                        more Days within the range supersede only the Days
                        specified.  The Days outside the range of the
                        subsequent nomination are unaffected.  Nominations
                        have a prospective effect only.  Seller shall
                        process all new or revised nominations that are
                        submitted by 11:30 a.m. Central Clock Time and
                        received by 11:45 a.m. Central Clock Time on the
                        Day before the applicable Service Day.  Customer
                        may nominate zero (0) for a daily quantity, but in
                        the event Customer nominates a daily quantity in
                        excess of zero (0), such daily quantity shall not
                        be less than five hundred (500) Dth.  Customer
                        shall also inform Seller in advance of each Month
                        of the desired order of priority of injections and
                        withdrawals under each Agreement and Seller may
                        rely thereon (or in the absence of such
                        information, upon Seller's judgment) if allocation
                        under such Agreement is required.
