TRANSPORTATION GENERAL TERMS AND CONDITIONS

(Continued)

6. INSPECTION OF EQUIPMENT AND RECORDS

6.1 Inspection of Equipment and Data: GTN and Shipper shall have the

right to inspect equipment installed or furnished by the other, and

the charts and other measurement or test data of the other, at all

times during business hours; but the reading, calibration and

adjustment of such equipment and changing of charts shall be done

only by the entity installing or furnishing same. Unless GTN and

Shipper otherwise agree, each shall preserve all original test

data, charts and other similar records in such party's possession,

for a period of at least six (6) years.

6.2 Information for Billing: When information necessary for billing by

GTN is in the control of Shipper, Shipper shall furnish such

information, estimated if actual is not available, to GTN on or

before the third (3rd) working day of the month following the month

transportation service was rendered. If shipper furnishes

estimated information, the actual information shall be furnished to

GTN on or before the fifth (5th) working day of the month following

the month transportation service was rendered.

6.3 Verification of Computations: GTN and Shipper shall have the right

to examine at reasonable times the books, records and charts of the

other to the extent necessary to verify the accuracy of any

statement, charge or computation made pursuant to these

Transportation General Terms and Conditions and to the rate

schedules to which they apply, within twelve (12) months of any

such statement, charge or computation. The time limitation for

disputing allocations shall be six (6) months from the date of

initial month-end allocation with a three-month rebuttal period,

provided, however, that this limitation shall not apply in the case

of a deliberate omission or misrepresentation or mutual mistake of

fact, and shall not diminish the parties' other statutory or

contractual rights. In accordance with NAESB Standard 2.3.11,

Version 1.8, a meter adjustment or correction becomes a prior

period adjustment after the fifth (5th) business day following the

Business Month. Any measurement of prior period adjustments are

taken back to the production month. These provisions are in

accordance with NAESB Standard 2.3.7, Version 1.8, which

establishes a cutoff for the closing of measurement of 5 business

days after business month.
