RATE SCHEDULE IBS

-----------------

(3) MEP shall account separately under each IBS

Agreement for all nominations to each specified end-use facility and

for volumes actually utilized at each end-use facility; provided,

however, that to the extent aggregation is permitted under Section

7(c) hereof, MEP shall account for all aggregated facilities on an

aggregated basis. Any difference on any Day between nominations and

physical gas flow under the linked FTS or ITS Agreement to the

specified end-use facility or facilities in the direction of swing

specified in the Access Request for that Day shall be allocated to

the IBS Agreement unless otherwise expressly agreed. The resulting

volume, which may be positive or negative, is the IBS Balance. Such

differences in the opposite direction from the Access Request shall

be allocated to the linked transportation Agreement or to other

services contracted by Shipper pursuant to a predetermined allocation

Agreement. Service hereunder allows Shipper to have daily imbalances

or variances within the level of the confirmed Access Request.

Volumes allocated to the IBS Agreement hereunder shall be treated as

unauthorized overrun if the resulting IBS Balance is not within the

volume level consistent with Shipper's confirmed Access Request under

this Section 6. Volumes allocated to the IBS Agreement hereunder in

excess of the maximum daily access volume or the maximum allowable

cumulative IBS Balance which are consistent with the confirmed Access

Request shall be authorized overrun under Section 8 of this Rate

Schedule IBS.

IBS Balances under an IBS Agreement by at least one half hour prior

to the time timely nominations are due for the next Gas Day. MEP

shall identify both the IBS Balance for the Day and the cumulative

IBS Balance. In the event that an allocation under Section 6(b)

results in Shipper having a positive or negative IBS Balance, then

unless otherwise agreed, Shipper shall be obligated to make a timely

IBS Payback nomination under the linked transportation Agreement

based on such timely information provided by MEP in the next daily

nomination cycle up to its MDQ under the linked transportation

Agreement to bring its IBS Balance for a day to zero (IBS Payback

nomination). Such IBS Payback nominations may also be made at the

time intraday nominations are due under the next Daily nomination

cycle. MEP may adjust such IBS Balance information in future periods

and Shipper's future payback obligations shall be adjusted

accordingly, but Shipper may rely on any information provided by MEP
