(d) Calculate the Lost, Unaccounted For and Other Fuel Gas

quantity by subtracting from the fuel quantity in (a) the

fuel quantity in (b) and adding the fuel quantity in (c)

above, and then adding a fuel quantity attributable to any

previously deferred Excess L&U Quantity (by dividing the

dollar value of the deferral by Transporter's Cash Out Index

Price for the current period). Should the resulting Lost,

Unaccounted For and Other Fuel Gas quantity be a negative

amount, such amount will be deemed to be an Excess L&U

Quantity and will be excluded from the calculation. Except

as provided below, Excess L&U Quantity will be deferred and

applied in future Lost, Unaccounted For and Other Fuel Gas

filings when the calculations of any these future quarterly

filings result in positive percentage.

(i) Excess L&U Quantities will be valued at the Cash Out

Index Price, as posted on Transporter's EBB, for the

month the Excess L&U Quantities are calculated and

deferred.

the Excess L&U Quantity when any of the following occur:

(1) The Excess L&U Quantity exceeds 250,000 Dth; or

consecutive calendar quarters; or

(3) Any Excess L&U Quantities that remain outstanding

at the time of Transporter's annual Fuel true-up

calculations pursuant to Section 13.5 below; or

Shipper's L&U Receipt Quantity to the total L&U Receipt

Quantity during the Period.
