2. APPLICABILITY AND CHARACTER OF SERVICE (continued)

2.5 Since this Rate Schedule provides compression service involving a

single receipt and delivery point, the Tariff provisions applicable

to segmentation, secondary scheduling and flexible receipt and

delivery points are not applicable.

3. SERVICE CHARGES

3.1 Reservation Charge. Shipper shall be charged each Month a reservation

charge (R1) determined by multiplying the R1 Reservation Rate set

forth in the Agreement by Shipper's MDQ. Shipper's liability for the

reservation charge and surcharges shall begin to accrue on the

effective date set forth in the Agreement.

3.2 Commodity Charge. Shipper shall be charged an amount obtained by

specified in its Agreement.

3.4 Adjustment of Rates.

(a) Subject to the terms of the Agreement, Transporter reserves the

right to prescribe and/or to adjust at any time any of the rates

applicable to any individual Shipper without adjusting any other

rate applicable to that Shipper or applicable to any other

Shipper; provided, however, that such adjusted rate(s) shall not

exceed the applicable maximum recourse rate(s) nor shall they be

less than the applicable minimum recourse rate(s), set forth on

the Statement of Rates. Such minimum and maximum rates shall not

be applicable to service provided pursuant to Section 4.17 of the

General Terms and Conditions of this Tariff.

(b) Downward adjustment from the maximum rate shall be for a specific

term. Unless otherwise agreed, at the expiration of the Term of

Rate specified in Exhibit "B" of the Agreement, the rate for

service, shall revert to the maximum allowable recourse rate,

including applicable surcharges, under this Rate Schedule. This

condition shall not apply to service provided pursuant to Section

4.17 of the General Terms and Conditions where rate conditions of

the Agreement shall govern.
