scheduling information provided by Shipper's Nominating Agent. By

designating Nominating Agent, Shipper agrees to indemnify and hold HIOS

harmless from all suits, actions, debts, accounts, damages, costs,

losses, and expenses arising in any way from the actions of Shipper's

Nominating Agent on behalf of Shipper, the failure of Shipper's

Nominating Agent to act on behalf of Shipper, or the reliance of HIOS

upon the information provided to HIOS by Shipper's Nominating Agent.

7.2 Nominations. All nominations shall include begin and end dates.

Shippers may nominate several days, months, or years, provided that the

nominations begin and end dates are within the term of the Shipper's

contract and are not less than one day. All nominations, excluding

intraday nominations, may be rolled over. All nominations, including

intraday nominations, shall be based on a daily quantity. All

nominations, including intraday nominations, that are not made through

HIOS' Interactive Internet Website, shall be made using HIOS' Nomination

Request Form set forth on Sheet No. 174, which form may be changed by

HIOS from time to time through an appropriate filing with the

Commission. If the nomination, or intraday nomination, is made through

HIOS' Interactive Internet Website, that nomination shall include all

Commission-approved data elements specified by HIOS on its Interactive

Internet Website. Nominations relative to imbalance correction

quantities and any overrun quantities shall be identified by transaction

type and nominated separately. To the extent Shipper desires to change

its nomination for any day(s) within the nomination period, Shipper must

submit a new nomination for such day(s). When a nomination for a date

range is received, 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days within that range, the previous nomination is superseded by the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.
