(b) National Fuel's Rate Schedule X-54 Transportation Service - Seller shall retain from

Buyer's withdrawal quantities hereunder, equivalent quantities retained by National

Fuel under its Rate Schedule X-54 transportation service. Effective November 1, 2007

National Fuel's Rate Schedule X-54 fuel allowance is 0.5% of the volumes received for

transportation. The applicable fuel retention factor under this Section 8.1(b) will be

used by Seller in the calculation of an annual adjustment to Buyer's Storage Gas

Balance as described in Section 8.1(c) below;

track an annual adjustment made by National Fuel to Seller's storage inventory under

National Fuel's Rate Schedule SS-1 related to transportation purchased by Seller under

National Fuel's Rate Schedule X-54. Beginning April 2008 and each April thereafter,

National Fuel will compare the retained volume under Rate Schedule X-54 during the

preceding months of April through March with the metered volumes of gas used as

compressor fuel for those same preceding months for transportation under Rate Schedule

X-54. National Fuel will then make an adjustment to Seller's storage inventory level

under Rate Schedule SS-1 no later than May 1 each year for the difference between the

retained volume and the metered volume. Accordingly, Seller will adjust annually,

pursuant to a tariff filing to be made no later than June 1 each year to be effective

May 1 of that same year, Buyer's Rate Schedule SS-2 Storage Gas Balance, as necessary,

to pass through the impact to Buyers of National Fuel's annual adjustment to Seller's

Rate Schedule SS-1 storage inventory. Seller will not assess Buyer any charges in

conjunction with the annual pass through adjustment and such pass through adjustment
