7.2 Estimates and Balancing. Estimates of fuel gas, boil-off gas, and

unaccounted-for gas may be utilized by KLNG to establish

Customer's LNG available for delivery at any time, but final

determination shall be made as soon as practicable, and departures

of estimates of such quantities from such finally determined

quantities shall be balanced out as soon as practicable. The

cutoff for fuel gas and boil off gas for final determination for

the closing of measurement is 5 days after the business month.

this tariff shall be Dth. All quantities of LNG measured, whether

in the gaseous phase or the liquid phase, shall be reduced to

8.2 LNG Deliveries in Gaseous Phase. LNG deliveries in the gaseous

phase shall be first measured in Mcf and then converted to Dth by

determining the Total Heating Value per cubic foot as delivered,

multiplying such Total Heating Value by the number of cubic feet

delivered, and dividing by one million.

gaseous phase shall be one cubic foot of gas at a temperature

of 60 degrees Fahrenheit and an absolute pressure of 14.73
