any amounts of less than $10,000. If resolution of the

dispute is in favor of Shipper and the Shipper furnished

a surety bond instead of paying the disputed amount, then

El Paso shall refund to Shipper the costs incurred in

securing that surety bond for this dispute. This section

does not apply to ordinary adjustments of overcharges and

undercharges in accordance with Section 6.5.

6.5 Adjustment of Overcharge and Undercharge - If it shall be

found that at any time or times, within the time limits of

Section 6.7 below, Shipper has been overcharged or

undercharged in any form whatsoever under the provisions

hereof as a result of an error in billing for which El Paso is

solely responsible and Shipper shall have actually paid the

bill containing such overcharge or undercharge, then, unless

mutually agreed otherwise, within thirty (30) days after the

final determination thereof, and except where otherwise

required by statute, rule, regulation or order, El Paso shall

refund the amount of any such overcharge, with interest

thereon at the then effective rate computed in the same manner

as set forth in Section 6.4 above, and Shipper shall pay the

amount of any such undercharge, with interest thereon at the

then effective rate computed in the same manner as set forth

in Section 6.4 above. Interest on overcharges or undercharges

shall be calculated from the time such overcharge or

undercharge was paid to the date of refund or payment,

respectively; provided, however, neither El Paso nor Shipper

shall calculate or pay interest on any amounts of less than

$10,000. This section does not apply to payments subject to a

billing dispute in accordance with Section 6.4.

6.6 Delayed Bill or Notice - If El Paso fails to render or

otherwise fails to mail any bill by the fifteenth (15th) day

of the month then the time of payment shall be extended by one

(1) day for each day that the rendering of said bill is

delayed unless Shipper is responsible for such delay. If

El Paso fails to render or otherwise fails to mail any notice

within the time specified in this Billing and Payment Section,

then the time for Shipper's response to such notice shall be

extended by one (1) day for each day that the rendering of

said notice is delayed unless Shipper is responsible for such

delay.
