GENERAL TERMS AND CONDITIONS

(Continued)

3. MEASUREMENT PROCEDURES (Continued)

3.6 New Measurement Techniques. If at any time during the term

hereof a new method or technique is developed with respect to gas

measurement, or the determination of the factors used in such gas

measurement, such new method or technique may be substituted for the

method set forth in this Section 3 when, in MRT's sole discretion,

employing such new method or technique is advisable. MRT shall notify

Customer in writing of any such election prior to actually implementing

such substitution.

3.7 Gas Stream Pulsations. Gas shall be delivered to MRT free

of pulsations detrimental to accurate measurement.

3.8 Testing and Repair of Equipment. The measurement and

appurtenant facilities at the MRT receipt and delivery point(s) shall be

kept accurate and in repair by the party operating said facilities. In

order to ensure the accuracy of the measuring equipment, the party

operating said equipment will perform such tests as it may deem

necessary on a monthly basis or as often as MRT deems necessary in

actual practice, and will repair and adjust any measuring equipment

found to be inaccurate so that the registration thereof will be

accurate. Each party agrees to give the other reasonable notice of such

tests so that if the other party desires it may have its representatives

present.

Each party shall have the right, at any time, to challenge the

accuracy of any measuring equipment used hereunder and, when so

challenged, the equipment shall be tested by the party operating the

challenged equipment. If, upon testing, the challenged equipment is

found to be in error, then it shall be repaired and calibrated. The

cost of any such special testing, repair and calibration shall be borne

by the party requesting the special test if the percentage of inaccuracy

is found to be two percent (2%) or less; otherwise, the cost shall be

borne by the party operating the challenged measuring equipment.
