                A. Communication of Pricing and Capacity Information.  Northern has
                   established and maintains an Internet website to comply with the requirements
                   of contemporaneous communication of and equal and timely access to certain
                   information to all "potential shippers."

                   time, is posted on Northern's website.  Therefore, Northern will not provide
                   paper copies of the tariff to its customers and interested state commissions
                   unless specifically requested to do so.

                   In addition to general information regarding the availability and
                   pricing of transportation services and the availability of pipeline
                   capacity (at receipt points, on the mainline, at delivery points, in
                   storage fields, new capacity and capacity as to which Northern has
                   exercised its right of pregranted abandonment), Northern will post
                   information with regard to the Right of First Refusal process,
                   capacity release, imbalance transfers, curtailment, points available
                   for nominations, points available for pooling, and open
                   season information. Shipper has the option to directly post capacity release
                   terms.  Northern will also post such pricing and capacity information upon
                   specific request by shippers and potential shippers.  Additionally,
                   Northern will post capacity wanted notices for prospective Shippers.
                   Northern will regularly remove information as to completed
                   transactions and other matters which have become obsolete.

                   Daily back-up records will be maintained for three years and will be
                   accessible to customers in electronic form upon written request.
                   Shipper shall reimburse Northern, upon billing, for any copying and
                   mailing costs associated with such requests.

                   charges, potential shippers should contact Northern through use of the
