3.2 Discounted Recourse Rates.

(a) Transporter reserves the right to temporarily discount at any

time the Recourse Rates for any individual Shipper under any

service agreement without discounting any other Recourse Rates for

that or another Shipper; provided, however, that such discounted

Recourse Rates shall not be less than the Minimum Currently

Effective Rates set forth on Sheet No. 5 of this Tariff, or any

superseding tariff. Such discounted Recourse Rates may apply to

specific quantities of gas (such as quantities above or below a

certain level or all quantities if quantities exceed a certain

level), quantities of gas transported during specific time

periods, and quantities of gas transported from specific receipt

points and/or to specific delivery points, within specific

corridors, or within other defined geographical areas. If

Transporter discounts any Recourse Rates to any Shipper,

Transporter will file with the Commission any required reports

reflecting such discounts.

(b) If Transporter elects to grant a temporary discount, it will

do so without amending Shipper's Service Agreement. The temporary

discount will be electronically granted using the Rate Schedule TI-

1 Temporary Discount form available in Northwest Passage on

Transporter's Designated Site. Shipper's electronic completion of

the Temporary Discount form constitutes agreement by the Shipper

to the discount and Transporter's electronic acceptance

constitutes Transporter's granting of the discount.

Shipper may select an option which will automatically increase (by

a stated dollar increment per dth) the granted rate up to the rate

that will increase the likelihood of such quantities being

scheduled pursuant to Section 12 of the General Terms and

Conditions.
