GENERAL TERMS AND CONDITIONS (continued)

(2) PDA duration - PDA's shall remain in effect until a

replacement PDA is received from the point operator,

or designee; provided, however, PDA's shall be updated

at the beginning of each month. The PDA may need to

be updated as the nominations at the point change.

3.4 Scheduling and Allocation

Each nomination under this section shall be considered an

original nomination and shall be replaced to be changed.

When a Shipper includes a date range as part of its

nomination, each day within that range is considered an

original nomination. When a subsequent nomination is

received for one or more days within that range, the

previous nomination shall be superseded by the subsequent

nomination only to the extent of the days specified. The

days of the previous nomination outside the range of the

subsequent nomination are unaffected. Nominations have a

prospective effect only. Subsequent nominated quantities

shall represent replacement daily quantities. All

nomination procedures that apply to regular nominations

(excluding timelines), including quick response, confirming

with upstream and downstream parties and scheduling, shall

also apply to hourly nominations. The sending party shall

adhere to nomination, confirmation and scheduling deadlines.

It is the party receiving the request who has the right to

waive the deadlines.

(1) Transporter shall support the following standard

nomination cycles:

(i) The Timely Nomination Cycle: 11:30 a.m.
