Footnotes

1/ Released capacity may be sold at a volumetric rate. Shippers

releasing capacity on a volumetric basis may not specify a rate above the

maximum rate stated on this Statement of Rates, except for short-term

capacity releases for a term of one year or less that are not subject to the

maximum rate, and must notify Overthrust of the criteria by which bids are to

be evaluated.

2/ Refer to § 7 of the General Terms and Conditions.

3/ Refer to § 16 of the General Terms and Conditions.

4/ If on any day Shipper exceeds its RDC without Overthrust's consent,

an evaluation will be made as to whether it is a critical or non-critical

event, i.e., whether or not the overrun caused operational problems. Shipper

shall then pay the indicated rate for the unauthorized overrun service. Any

associated revenue, above administrative costs, will be credited to all non-

offending shippers.

5/ Usage charges are applicable to transportation services that are

released at a volumetric rate.

6/ Short-term capacity releases for a term of one year or less are

not subject to the maximum rate.

NOTE: The monthly rates stated on Overthrust's Statement of Rates may

be converted to a daily rate by multiplying the monthly base tariff rate

times the number of months in the rate period and dividing the result by the

number of days in the rate period. The result is rounded to the fifth

decimal place.
