4.2 Rate Changes:

(a) Midwest may from time to time and at any time

selectively adjust any or all of the rates

charged to any individual Shipper for which a

Maximum Rate and Minimum Rate appearing in the

effective Statement of Rates; provided, however,

that such adjusted rate(s) shall not exceed the

applicable Maximum Rate(s), nor shall they be

less than the Minimum Rate(s), set forth on such

Statement of Rates. Midwest shall have the

right to charge the Maximum Rate at any time as

a condition for new service or for continuation

of service under an existing Agreement. Midwest

shall make all information filings required by

the Commission's regulations with respect to any

charges at less than the Maximum Rate. Whenever

Midwest adjusts the rate to be charged to a

Shipper pursuant to this Section 4.2, notice

thereof shall be given to Shipper not less than

seventy-two (72) hours prior to the effective

date of such adjustment.

(b) Midwest may from time to time seek authorization

from the Commission and/or other appropriate

body to change any rate(s) and terms set forth

herein. Nothing herein contained, shall be

construed to deny Shipper any rights it may have

under the Natural Gas Act, as amended, including

the right to participate fully in rate

proceedings by intervention or otherwise to

contest changes in rates or terms in whole or in

part; provided, however, that such unilateral

rate and terms changes will not in any way

affect the rights and obligations of Midwest and

Shipper under the Firm Storage Agreement.
