2. APPLICABILITY AND CHARACTER OF SERVICE: (continued)

(b) When Shipper schedules removal of its parked quantities, all such

quantities shall be deemed received at the point at which such

quantities were originally received into Transporter's system,

unless Transporter agrees otherwise. If such removal occurs at a

point other than such agreed to point, Shipper may be required to

nominate under separate Service Agreements with Transporter and

pay rate(s) applicable to such service to effectuate removal of

such Gas from the other points.

2.8 (a) Shippers utilizing the loan option under this Rate Schedule shall

be obligated to return the quantity of gas advanced by

Transporter in accordance with the agreement between Transporter

and Shipper. Additionally, Shipper must return all or any

portion of the loaned quantity if required by Transporter upon

forty-eight (48) hours (or such longer period as may be

specified) notice. Failure to do so will result in the

assessment of the charges described in Section 5.2(b) of this

Rate Schedule; provided, however, that Transporter shall not

assess such charges if, and for so long as, Shipper nominated to

return such quantities in accordance with its agreement with

Transporter or Transporter's notice, and Transporter was unable

to schedule and receive such quantities in accordance with such

nomination.

(b) When Shipper returns loaned quantities to Transporter, such

return shall occur at the points agreed to by Transporter, and

Transporter shall have the right to adjust subsequent

transportation invoices (under other Rate Schedules) of Shipper's

to reflect any additional amounts owed by Transporter if such

return occurs at a point different than the point agreed to.

2.9 For purposes of Section 14.5 of the General Terms and Conditions of

this Tariff, a Shipper may receive services under this Rate Schedule

by providing security in an amount sufficient to cover up to the

maximum amount of charges which could be incurred hereunder. If there

is an increase in gas prices over the term of a particular transaction

such that Transporter deems initial security amounts insufficient,

Transporter shall have the right to require an increased security

amount.
