B. CONTRACT QUANTITY

(1) The request must specify the MDQ under the IBS Agreement.

The MDQ of the IBS Agreement may be equal to or less than

the MDQ of the linked transportation Agreement and shall

represent the maximum quantity to be parked or loaned

hereunder on any Gas Day to balance variations between

actual and scheduled flows at the Delivery Point under the

linked transportation agreement. If the transportation

Agreement is linked to more than one IBS Agreement, then

the sum of the MDQs under all IBS Agreements served by that

linked transportation Agreement must be equal to or less

than the transportation contract MDQ. Subject to the above

limitations, the MDQ under the IBS Agreement shall be as

specified by Shipper in its request for service; provided,

however, that the MDQ may not exceed the higher of: (i)

the highest daily usage served by Transporter at the

Delivery Point during the prior twelve (12) months; or (ii)

the highest daily usage which will be served by Transporter

at such Delivery Point during the ensuing twelve (12)

months as reasonably projected by Shipper and Transporter.

The MDQ shall be re-determined at the request of either

Shipper or Transporter no earlier than six (6) months after

the then most recent MDQ determination or at any time by

mutual agreement.

(2) The request must specify the Cumulative Balance under the

IBS Agreement. The Cumulative Balance shall represent the

maximum quantity owed by Shipper as parks or loans, as

delineated separately for total cumulative park or loan

quantities in Dth, and shall not exceed two times the IBS

Agreement MDQ, unless otherwise agreed to in writing.
