TRANSPORTATION GENERAL TERMS AND CONDITIONS
                             (Continued)
   
1.  DEFINITIONS
       1.  Agent - Any party Shipper may contract with, subject to approval by
Transporter of such contract which may not be unreasonably withheld, for
purposes of administering Shipper's Service Agreement with MIGC.  An Agent has
only those rights designated in writing by such Shipper to MIGC.
   
       2.  "Bumping" or "Bump" shall mean the reduction of a previously
scheduled and Confirmed Transportation Quantity to permit MIGC to schedule and
confirm a firm Transportation Nomination which has a higher priority and which
was submitted as an Intra-day Nomination.  Bumping that affects transactions on
multiple Transportation Service Providers' systems should occur at grid-wide
synchronization times (9:00 a.m. and 5:00 p.m. only, per Standards Board
Standards 1.3.39).  MIGC shall provide direct notice of bumping, and of any
applicable penalties which will apply to the interruptible shipper, by fax or
EDI in advance of such bumping.
   
       3.  British Thermal Unit ("Btu") - The reporting basis for Btu is
standardized as 14.73 dry psia and 60 degrees Fahrenheit (101.325 kPa and 15
degrees C. and dry).  Standardize the reporting basis for gigacalorie as
1.035646 Kg/(cm squared) and 15.6 degrees C. and dry.  One (1) Btu shall mean
one British Thermal Unit and is defined as the amount of heat required to raise
the temperature of one (1) pound of water from fifty-nine degrees Fahrenheit
(59 degrees F)to sixty degrees Fahrenheit (60 degrees F) at a constant pressure
of fourteen and seventy-three hundredths pounds per square inch absolute
(14.73 psia).  Total Btu's shall be determined by multiplying the total volume
of natural gas delivered times the gas heating value expressed in Btu's per
cubic foot of gas adjusted on a dry basis.
   
       4.  Business Day - Monday through Friday from 9:00 a.m. to 6:00
p.m., Central Clock Time (8 a.m. to 5 p.m. Mountain Clock Time), excluding
Federal Banking Holidays.
   
       5.  Confirmation - shall mean the verification of the Confirmed
Quantity by the Confirming Parties.  The Explicit Confirmation process requires
that the Confirming Party respond to a request for confirmation or initiate an
unsolicited confirmation response.  Absent mutual agreement to the contrary,
Explicit Confirmation is the default methodology (Standards Board Standard
1.3.40).
