                                      GENERAL TERMS AND CONDITIONS


                   Voluntary Contribution Mechanism.  Shippers may voluntarily choose to
                   contribute to GRI programs through a "check-the-box" mechanism on Shipper
                   invoices.  The "check-the-box" mechanism will permit shippers to specify
                   the level of contribution and the project(s) or project area(s) to be
                   funded at the time of the Shipper's contribution payment.  Northern shall
                   serve as voluntary collection agent for such collections and amounts
                   collected pursuant to the "check-the-box" mechanism will not be considered
                   part of pipeline rates.

                   Remittance to G.R.I.  Northern shall remit to G.R.I., not later than
                   fifteen (15) days after the receipt thereof, all dollars received by
                   virtue of the Voluntary Contribution Mechanism, less any amounts properly
                   payable to a Federal, State or Local authority relating to the dollars
                   received hereunder.  Northern shall indicate to the GRI the amounts
                   applicable to specific project(s) and project area(s), if so indicated by
                   Shipper(s).

                   Purpose.  This Section 36 describes the procedures by which Northern
                   may revise its throughput rates annually pursuant to the provisions
                   of 18 CFR 154.38(d)(6) of the Commission's Regulations to recover the
                   annual charges assessed Northern by the Commission pursuant to Part
                   382 of its Regulations.  Northern intends to recover these costs
                   under these tariff provisions and not in a NGA Section 4 rate case.
