If publication or the specific postings contained therein that are listed

substitute index, COMPANY will calculate the Index Price each month based

on an industry-wide weekly index for Transco Zone 4.

during the month under each agreement subject to netting under Section

14(a) above to determine a net system imbalance for the month. Subject to

pursuant to Section 30 of the General Terms and Conditions, if the net

system imbalance does not exceed either 100,000 Dth of gas owed to COMPANY

or 50,000 Dth of gas owed to SHIPPERS, the price to be paid by COMPANY or

SHIPPER hereunder for each SHIPPER'S respective Net Monthly Imbalance shall

Minority Imbalance or a Majority Imbalance.
