GENERAL TERMS AND CONDITIONS

(Continued)

13. FUEL AND L&U (Continued)

13.5 The FL&U Requirement shall be calculated separately for all

Incremental FL&U Percentages. FL&U shall be the sum of separately

stated reimbursement percentages for Fuel Gas and for L&U. The

FL&U Requirement shall include the following components:

(a) "Projected FL&U Requirement" shall mean the quantity of

Gas which is the sum of the Fuel Gas and the Lost and

Unaccounted-for Gas projected by Transporter to be

required to support the anticipated Transportation Service

for all Shippers under all Rate Schedules during the

projected period.

(b) "FL&U Requirement Adjustment" for December 1, 2009 forward

shall mean the quantity of Gas which is the difference

between: (i) the actual quantities of FL&U experienced by

Transporter adjusted for anticipated changes in system

operations; and (ii) the quantities of Gas retained by

Transporter through application of the FL&U Percentages

during the data collection period adjusted for any prior

under or over-recoveries resulting from a prior true-up.

Determination of the actual quantities of FL&U experienced

during this period shall include an adjustment to

eliminate the effect of changes in system line pack, if

any. The data collection period shall be the most recent

twelve months of available data ending on the last Day of

the second previous Month before a FL&U Percentages filing

is to be made (i.e., if the FL&U Percentages filing is to

be made on October 31, the data collection period would be

the previous twelve months ending on August 31).
