Northwest plans to make a tariff filing to: (1) modify the Clay Basin revenue crediting language in Section
24 of the GT&C to make the handling of discounted transportation services consistent with other crediting
procedures stated within the Tariff and to also clarify how shippers are allocated their pro-rata share of
the Clay Basin revenue credit if paying a negotiated rate above maximum base transportation rate; (2)
add language to clarify OFO obligations under the Rate Schedule TF-2 in Section 14.15; and (3) modify
language in Section 9 Force Majeure to clarify that neither Transporter nor Shipper shall be relieved from
obligations to make payments of amounts then due, including reservation charges.

A draft copy of the proposed filing is available on Northwest's website under Regulatory/Proposed Tariff
Filings at the following link: http://www.northwest.williams.com/NWP_Portal/  (click 'Regulatory,' then
'Proposed Tariff Filings').
