STATEMENT OF RATES FOR TRANSPORTATION OF NATURAL GAS

FOOTNOTES

(1) The transportation rate shall be adjusted to include the FERC Annual

Charge Adjustment (ACA).

(2) For Capacity Release transactions only, Transporter has adopted the

following NAESB standards. On the bidding formats, the number of

decimal places for offers, bids and awards shall be equal to the

number of decimal places in Transporter's stated rates (NAESB Standard

5.3.21). Converting a Daily rate to a Monthly rate is accomplished by

multiplying the Daily rate times the number of Days in the rate

period, dividing the result by the number of Months in the rate period

and taking the remainder out to 5 decimal places, and rounding up or

down to the Transporter's specified decimal place. Converting a

Monthly rate to a Daily rate is accomplished by multiplying the

Monthly rate by the number of Months in the rate period; dividing the

result by the number of Days in the rate period, taking the remainder

out to 5 decimal places, and rounding up or down to the Transporter's

specified decimal place (NAESB Standard 5.3.22). Furthermore, for

capacity release purposes, all Tariff rates shall be adjusted to

reflect a standard calculation of Daily and Monthly rates, in

conformance with NAESB Standard 5.3.23.

(3) The "FL&U" percentage(s) shall be adjusted quarterly. Such

adjustment(s) shall not subject Transporter to any obligation to

justify its other costs or revenues or throughput. Transporter shall

be allowed to adjust the percentage(s) independent of and without

regard to other rates. As applicable to the use of off-system

capacity, Transporter will assess L&U or FL&U Third Party Charges

pursuant to General Terms and Conditions Section 4.5(b); in the

absence of any provision in the FTSA to the contrary, any Shipper

utilizing off-system capacity will be responsible for all costs,

charges, and surcharges (including but not limited to L&U and when

assessed, fuel) imposed by the off-system capacity provider. To the

extent off-system capacity is used in conjunction with Transporter's

mainline and/or incremental rate lateral facilities' capacity,

Transporter will also assess the applicable mainline and/or

incremental rate lateral L&U or FL&U charges. To the extent off-

system capacity is not used in conjunction with Transporter's mainline

and/or incremental rate lateral facilities' capacity, Transporter will

only assess the off-system L&U or FL&U charges.
