GENERAL TERMS AND CONDITIONS

----------------------------

(a) In the case where an online chromatograph is used,

the results will be applied continuously during calculation. The

average of the hourly heating value during periods of flow each Day

shall be recorded and considered as the heating value of the Gas

delivered to MEP or Shipper.

(b) In the event a continuous Gas sampler is

installed, then the heating value of the composite sample so taken

shall be considered as the heating value of the Gas for the

applicable period. Alternatively, the results may be applied

prospectively beginning on the Day the results become available after

agreement by both parties.

run on the measuring party's chromatograph at another location. The

result of a spot sample shall be applied to Gas deliveries as of the

Day the results are available and for all succeeding Days until a new

sample is taken.

(d) All heating value determinations made with a

chromatograph shall use physical gas constants for Gas compounds as

outlined in the GPA Std 2145-00 Rev 1 Table of Physical Constants of

Paraffin Hydrocarbons and other Compounds of Natural Gas and any

subsequent amendments or revisions to such Report to which the

parties may mutually agree. The moisture content of the Gas shall be

determined as often as necessary and practical to determine the

actual heating value of the Gas stream.

(e) The calculations (for Btu) shall be based on dry

Gas if the Gas at the measurement points contains less than five (5)

pounds of water per MMcf. If the Gas at the measurement points

contains more than five (5) pounds of water per MMcf, the appropriate

factor determined by MEP in the exercise of its reasonable judgment

for the actual water vapor content will be applied to the Btu

calculations to correct for this water content.

(f) The specific gravity of the Gas flowing through

the meter or meters may be determined by the use of a chromatograph

or by analysis of Gas collected in spot and continuous samplers.

Specific gravity shall be updated whenever the heating value of the

Gas is updated. All specific gravity determinations made with a

chromatograph shall use physical Gas constants for Gas compounds as
