4. CHANGE IN RATES

Transporter shall have the unilateral right to file with the appropriate

regulatory authority and make changes effective in (a) the rates and

charges applicable to this Rate Schedule, (b) this Rate Schedule,

pursuant to which service hereunder is rendered; provided, however, that

the interruptible character of service shall not be subject to change

hereunder, and/or (c) any provisions of the General Terms and Conditions

applicable to this Rate Schedule. Such changes may be implemented

through a tariff filing. Transporter agrees that Shipper may protest or contest

the aforementioned filings, or may seek authorization from duly

constituted regulatory authorities for such adjustment of Transporter's

existing FERC Gas Tariff as may be found necessary to assure that the

provisions in (a), (b), or (c) above are just and reasonable.

5. PNR POINTS OF SERVICE

5.1 Transporter shall post, in a non-discriminatory manner, Parking

Points and Riding Points of service on Transporter's Internet Website.

Transporter may, at its sole discretion, post from time to time

additions or deletions to the list of available points of service.

If Transporter terminates a point where parked quantities are to be

returned to a Shipper or ridden quantities are to be returned to

Transporter, such point(s) shall remain available for the limited purpose

of completing such outstanding transactions unless Shipper and Transporter

mutually agree to utilize a different Parking Point or Riding Point.

5.2 In order to facilitate Park `N Ride Service under this Rate Schedule,

Parking Points and Riding Points shall be assigned new PNR Point of

Interest (POI) numbers. Each new PNR POI shall be associated with an

existing POI located at the same physical point on Transporter's system as

the new PNR POI. There shall be no transportation or

transportation-related fees associated with the nomination of any

gas quantities between the PNR POI and its associated existing POI.
