GENERAL TERMS AND CONDITIONS

(Continued)

10. TRANSPORTATION BALANCING

10.1 Customers shall use their best efforts to avoid delivering or

receiving quantities of gas which deviate from the quantities of gas

scheduled by MRT for transportation and redelivery hereunder, and shall

keep MRT advised of any material deviations from the quantities scheduled.

Each Customer shall have the responsibility to maintain a concurrent

balance between receipts and deliveries, adjusted for appropriate fuel

reimbursement, based upon the best information available to the Customer.

MRT will provide to its Customers through its electronic communication

system gas flow information each day and Customers will be able to access

such information. MRT shall also make available to each Customer any other

information regarding daily receipts and daily deliveries for Customer's

account which MRT possesses.

10.2 If deliveries by MRT are greater or less than the corresponding

receipts of gas by MRT for transportation, less any gas retained for fuel

reimbursement, the imbalance shall be adjusted or corrected in accordance

with the terms of this section in addition to any other charges or remedies

to which MRT may be entitled.

10.3 Receipt Variance Penalty

(a) For purposes of this section, a "Receipt Variance Period" is

defined as a period of seven consecutive days during a month.

(b) If the actual, or if unavailable the estimated, quantity of

gas received within a zone by MRT from a Customer or Pool Operator

pursuant to a transportation service agreement or pooling agreement

varies, either positively or negatively, by the greater of 10% or

50 MMBtu from the quantity scheduled during a Receipt Variance Period,

MRT may impose a penalty equal to the amount of the variation in

excess of the tolerance, multiplied by the maximum Rate Schedule ITS

rate set forth on Sheet No. 7 of this tariff. However, if an

interruptible Customer's scheduled and/or flowing quantities for a

day are reduced to an intraday nomination by a firm Customer, and the

interruptible Customer did not receive advance notice of such

reduction in accordance with Section 8.1(f)(i) above, such day's

scheduled and received quantities will not be considered to be part of

the variation for the applicable Receipt Variance Period.
