RATE SCHEDULE IBS (continued)

D. Transporter has the right to delay or limit IBS Payback. To the

extent Transporter does not confirm an IBS Payback nomination, or

the nomination is limited by MDQ under the IBS Agreement, Shipper

shall be obligated to make a timely IBS Payback nomination in

each subsequent daily nomination period until the IBS Balance for

that day has been eliminated; provided, however, that if

Transporter advises Shipper that no IBS Payback nominations will

be accepted until a specified future date or will be limited in a

specified way over a defined period for scheduling reasons, no

overrun charges under Section 6.5 or Section 7.1(A) shall apply

until Transporter has confirmed and permitted Payback volumes.

The IBS Payback period shall be extended by each day the IBS

Payback nomination is not confirmed by Transporter.

6.4 Each Daily Balance must be zeroed-out through the IBS Payback

nomination process in this Section 6 by the end of three (3) Gas Days

or such extended period allowed pursuant to Section 6.3D above. IBS

Balances for each Gas Day shall otherwise incur additional charges

equal to the Park/Loan Daily Balance Rate or the Mandatory Balancing

Provisions of this Rate Schedule IBS that shall otherwise apply, unless

otherwise agreed to in writing by Transporter.

6.5 The quantity parked or loaned each Gas Day to effectuate balancing

under the linked transportation agreement shall constitute the Daily

Balance. Each Daily Balance shall be accounted for separately for

purposes of applying Park/Loan Balance Rate charges, without netting of

Daily Balances, pursuant to the provisions of this Section 6. If

Shipper fails to nominate and deliver IBS Payback quantities to reduce

a Daily Balance (positive-park or negative-loan balance) in the next

Gas Day and at a level sufficient to rectify the daily IBS Balance

within three (3) Gas Days, then the Park/Loan Balance Rate shall apply,

with no tolerance or exemption, beginning on the fourth (4th) Gas Day

to the remaining Daily Balance quantity parked or loaned and shall

continue to be assessed each Gas Day thereafter and until the Daily

Balance for a Gas Day is nominated, confirmed and delivered so as to

eliminate the Daily Balance. IBS Payback nominations shall be applied

to the oldest Daily Balance ("first in, first out") and IBS Payback

quantities may be designated by Shipper as the first gas through the

meter for allocation under predetermined allocation agreements at

Receipt Points under the linked transportation agreement or the

specified Delivery Point under the IBS Agreement. The Park/Loan Balance

Rate, including charges associated with potential overrun of the IBS

Balance, will be assessed if Payback nominations are not effectuated
