GENERAL TERMS AND CONDITIONS (continued)

(iv) Once Transporter approves a specific pairing arrangement,

such arrangement shall remain in effect until terminated by

shipper or supplier, terminated by Transporter due to a

material change in Transporter's operations so that the

pairing arrangement creates undue risk of an HDP Problem or

until Transporter reduces the Hydrocarbon Dewpoint limit on

the segment(s) of Transporter's System that include the gas

subject to the pairing arrangement. If Transporter reduces

a Hydrocarbon Dewpoint limit, it will allow existing pairing

arrangements to continue, so long as the parties to such

arrangements notify Transporter within one (1) Business Day

of adjustment of the affected volumes to meet the newly

posted Hydrocarbon Dewpoint limit, and such volume

adjustments do not create undue risk of an HDP Problem.

(v) To the extent that Transporter determines that the pairing

proposal does not meet one or more of the above listed

conditions, Transporter will provide shipper or supplier a

written denial specifying the basis for the determination.

(vi) Transporter shall permit all shippers and suppliers

interested in pairing to post relevant data, including

contact information, on PASSKEY.

(d) Transporter shall post on PASSKEY each Receipt Point Hydrocarbon

Dewpoint value Transporter calculates, within 24 hours after

making the calculations, and the method by which the Hydrocarbon

Dewpoint value was calculated.

(e) Transporter shall post on PASSKEY each blended Hydrocarbon

Dewpoint and blended BTU values Transporter calculates for a line

segment of its system within 24 hours of such calculation.

(f) HDP Measurement - Transporter shall perform the Hydrocarbon

Dewpoint (cricondentherm) calculations for Section 3.1 using the

Peng-Robinson equation of state and C6+ assumptions consistent

with industry practices. Upon a shipper's request, Transporter

shall conduct a C9+ analysis; provided that in no event shall

Transporter be required to conduct such C9+ analysis at any one

receipt point more frequently than once every twelve months,

except if a new source of supply has been added at that point.

4. The design and construction of any facilities to be installed by Shipper

in order to comply with the quality specifications in Article II Section 3
