Formula Rates for Services up to Contract Demand:

The formula rate will be based on the following index prices as reflected for spot gas delivered to the pipelines at the points indicated, as represented

by the Midpoint price published in Gas Daily's Daily Price Survey for each day of the contract term ("Index Price"). If the information or publication

ceases to be published, the parties shall select another mutually agreeable Index Price. The Index Spread each day shall be equal to (a) the amount

remaining when the Index Price specified in (2) below is subtracted from the Index Price specified in (1) below, less (b) the Compressor Fuel Value

calculated as described below, less (c) $0.01 / Dth.

(1) Columbia Mainline

(2) REGT West

The Compressor Fuel Value shall be calculated by adding (i) the product of the applicable Compressor Fuel percentage as specified and in effect from time

to time in REGT's Tariff times the Index Price set forth in (2) above, plus (ii) the EPC tracker.

If the Index Spread for a day is less than or equal to $0.02 per Dth, then the unit rate (based on an assumed 100% load factor) per Dth of Contract Demand

shall be $0.02. If the Index Spread is greater than $0.02, then the unit rate per Dth of Contract Demand shall be the Index Spread. In any event, however,

the unit rate per Dth of Contract Demand shall never be below the greater of the applicable then effective minimum Tariff rate or $0.02.

Rate may default to maximum if Transporter is unable to collect Negotiated Rates for any reason during the term of the contract, and Shipper has termination

right in such event. Unless Transporter otherwise agrees, the Commodity Rate shall be the applicable minimum, and the rate for any authorized overrun

quantities shall be the greater of the applicable maximum Tariff rate or the applicable formula unit rate. Rate includes any applicable GRI, ACA, GT&C
