13. RECEIPT POINT FLEXIBILITY

Transporter will allow monthly amendments to receipt points

designated in Transportation Agreements under this rate schedule subject

to available capacity. Any Shipper who wishes to amend the receipt points

named in its Transportation Agreement shall submit an executed amendment,

which implements a revised Exhibit A, to Transporter by two working days

prior to the first of the month for which the change is desired, unless

otherwise agreed to by the parties. If Transporter determines that a

receipt point change request will be honored, notice of the approved

change will be posted on Transporter's electronic bulletin board at

least 24 hours prior to implementation of such change.

In addition, Transporter will allow, subject to available capacity

and confirmation of supply availability, temporary utilization of receipt

points not listed on Exhibit A to the executed Transportation Agreement in

the event of interruption of firm transportation due to capacity

constraints, or in the event of failure to deliver committed gas supplies

because of equipment failure, compressor malfunction, freezing, or similar

force majeure conditions. Transporter will provide such notice to

interruptible shipper of firm receipt point changes resulting from

capacity constraints or force majeure conditions as may be reasonable

under the circumstances. Transporter will notify interruptible customers

of receipt point changes resulting from capacity constraints on its system

when confirmation of nominations is made, pursuant to Section 14 of the

General Transportation Terms and Conditions.

Receipt point changes made pursuant to amendments or temporary

utilization of receipt points pursuant to this section shall be given

priority over all interruptible transportation requested through such

receipt points and the total volumes designated on any day for all receipt

points must not exceed Transportation Contract Demand.
