        <footnote id="F1">Williams Pipeline GP LLC (the General Partner) owns directly 4,700,668 Common Units, 10,957,900 Subordinated Units, 684,869 units representing a 2% general partner interest and certain incentive distribution rights (IDRs), which represent the right to receive an increasing percentage of quarterly distributions of the Issuer.  See also footnotes 3 and 4.  The Williams Companies, Inc. (Williams) owns 100% of Williams Gas Pipeline Company, L.L.C. (Williams Gas Pipeline), which owns 100% of the General Partner.  Accordingly, Williams and Williams Gas Pipeline may be deemed to be indirect beneficial owners of any securities held by the General Partner.</footnote>
        <footnote id="F2">Upon the closing of the initial public offering of the Issuer (the Offering) and in exchange for the contribution of certain assets to the Issuer by affiliates of Williams, the General Partner was issued 6,350,668 Common Units, 10,957,900 Subordinated Units, 684,869 units representing a 2% general partner interest and certain incentive distribution rights (IDRs), which represent the right to receive an increasing percentage of quarterly distributions of the Issuer.</footnote>
        <footnote id="F3">In connection with the Offering, the underwriters were granted the right to purchase up to an aggregate of 2,437,800 additional Common Units.  The underwriters exercised their option with respect to 1,650,000 Common Units.  Concurrently with the exercise of the option and in accordance with the terms of the Contribution, Conveyance and Assumption Agreement entered into in connection with the closing of the Offering, the Partnership redeemed 1,650,000 common units held by the General Partner, resulting in a reduction of the Common Units held by the General Partner to 4,700,668 Common Units.</footnote>
        <footnote id="F4">The 98% limited partnership interest in the issuer previously held by Williams Pipeline Services Company was reduced as a result of the dilutive effect of the Offering and was fully redeemed by the Issuer in connection with the Offering.  Williams Pipeline Services Company will no longer be a Section 16 reporter.</footnote>
        <footnote id="F5">The reporting persons disclaim beneficial ownership of the reported securities except to the extent of their pecuniary interest therein, and this report shall not be deemed an admission that the reporting persons are beneficial owners of the reported securities for purposes of Section 16 or for any other purpose.</footnote>
        <footnote id="F6">Each Subordinated Unit will convert into one Common Unit at the end of the subordination period, which will end once the Issuer meets certain financial tests set forth in its Partnership Agreement.  These financial tests include, among other things, that the distributions of available cash from operating surplus on the outstanding Common Units, Subordinated Units and General Partner Units equaled or exceeded the sum of the minimum quarterly distributions for each of the prior three consecutive, non-overlapping four-quarter periods and the adjusted operating surplus for the same period equaled or exceeded the sum of the minimum quarterly distributions on all of such outstanding units on a fully diluted basis. The Subordinated Units do not have an expiration date.</footnote>
