GENERAL TERMS AND CONDITIONS (Cont'd)

(f) Shipper shall have the option to either submit overrun quantities (nominations under firm

of all nominations. When nominations for overrun quantities are submitted as a separate transaction, they

must be identified as such by using the appropriate nomination transaction type.

(g) Except for intra-day nominations, Shipper may nominate for several days, months or years in one

day increments provided such nomination is within the begin and end dates of Shipper's Service Agreement.

(h) Shipper may submit intraday nominations according to the deadlines noted in Section 6.2(e). For

services that provide for intraday nominations and scheduling, there is no limitation as to the number of

intraday nominations which Shipper may submit at any one standard nomination cycle or in total across all

standard nomination cycles. Such intraday nominations may be used to request increases or decreases in total

flow, changes to receipt points, changes to delivery points, or to nominate new supply or market. All

intraday nominations shall be based on a daily quantity. Intraday nominations shall include an effective date

and time. The interconnected parties shall agree on the hourly flow of the intraday nomination, if not

otherwise addressed in Transporter's contract or tariff. During any Gas Day of interruption pursuant to

Section 16 (Interruptions of Service), a Shipper may not make intraday changes to receive or take gas if such

change would cause interruption of a Shipper using that receipt or delivery point as a firm secondary point

during that Gas Day. Shipper may make any such intraday changes only if the following requirements and
