     The information previously provided in response to this Item 2 is hereby amended by adding the following:

     In accordance with the provisions of General Instruction C to Schedule 13D, information concerning the executive officers, board of directors and each person controlling the Reporting Persons, as applicable (collectively, the “Listed Persons”), required by Item 2 of Schedule 13D is provided on Schedule 1 and is incorporated by reference herein. To the Reporting Persons’ knowledge, none of the persons listed on Schedule 1 as a director or executive officer of GP LLC, TWC or WES has been, during the last five years, (i) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors), or (ii) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration

     The information previously provided in response to this Item 3 is hereby amended by adding the following:

     At the closing of the Issuer’s public offering (the “Offering”) of 9,250,000 common units representing limited partner interests in the Issuer on December 11, 2007, the following transactions, among others, occurred pursuant to a Contribution, Conveyance and Assumption Agreement by and among the Issuer, GP LLC, WES, WE, Holdings and Williams Pipeline and the other parties thereto:

     GP LLC contributed a 100% Class A limited liability company membership interest and 20 Class Units representing 50% of the currently outstanding Class C limited liability company membership interest in Wamsutter LLC (“Wamsutter”) to the Issuer in exchange for aggregate consideration of $750 million, including 4,163,527 common units and an increase in GP LLC’s capital account in the amount of approximately $10.3 million to allow it to maintain in 2% general partner interest in the Issuer.

     On December 6, 2007, Mr. Michael H. Krimball, a member of the board of directors of GP LLC, acquired beneficial ownership of 20,000 common units in an open market transaction at a price of $38.15 per common unit. On December 6, 2007, the Shelly Stone Armstrong Trust dated August 10, 2004, acquired 5,000 common units in an open market transaction at a price of $38.25 per common unit. [Mr. Alan S. Armstrong, the Chief Operating Officer and a member of the board of directors of GP LLC, is the trustee of the Shelly Armstrong Trust.] On December 15, 2007, Mr. Krimball acquired beneficial ownership of an additional 663 common units as a grant of restricted common units under the Williams Partners GP LLC Long-Term Incentive Plan.

Item 4. Purpose of Transaction

      The information previously provided in response to this Item 4 is hereby amended by replacing the text thereof in its entirety with the following:

     The Common Units reported in Item 3 above were acquired for investment purposes.

     Pursuant to the Amended and Restated Limited Liability Company Agreement of GP LLC (the “GP LLC Agreement”), WES has the right to appoint the board of directors of GP LLC. Through the right to appoint the board of directors of GP LLC pursuant to the GP LLC Agreement, WES and, through its 100% direct ownership of WES, TWC have the ability to influence the management policies and control of the Issuer with the aim of increasing the value of the Issuer, and thus, the Reporting Persons’ investment.

     The Subordinated Units beneficially owned by WES are convertible into Common Units on a one-for-one basis once certain financial tests set forth in the Issuer’s Amended and Restated Agreement of Limited Partnership, as amended by Amendments No. 1, 2 and 3 thereto (as amended, the “Partnership Agreement”), are met. WES and the other owners of the Subordinated Units may distribute the Common Units issued upon conversion of the Subordinated Units to their respective members, although they may elect to dispose of some or all of the Subordinated Units earlier in public or private transactions.

     Pursuant to the terms of the Partnership Agreement, among other conditions, GP LLC may not be removed from its position as general partner of the Issuer unless 66²/3% of the outstanding units, voting together as a single class, including units held by GP LLC and its affiliates, vote to approve such removal and the Issuer receives an opinion of counsel regarding limited liability and tax matters. Any removal of GP LLC is also subject to the approval of a successor general partner by the vote of the holders of a majority of the outstanding units, voting as separate classes. The ownership of more than 33¹/3% of the outstanding units by GP LLC and its affiliates would give them the practical inability to prevent GP LLC’s removal.

     The Partnership Agreement contains specific provisions that are intended to discourage a person or group from attempting to remove GP LLC as the Issuer’s general partner or otherwise change the Issuer’s management. If any person or group other than GP LLC and its affiliates acquires beneficial ownership of 20% or more of any class of units, that person or group loses voting rights on all of its units. This loss of voting rights does not apply to any person or group that acquires the units from GP LLC or its affiliates and any transferees of that person or group approved by GP LLC or to any person or group who acquires the units with the prior approval of the board of directors of GP LLC.

     Under the Partnership Agreement, the Issuer has agreed to register for resale under the Securities Act and applicable state securities laws any Common Units, Subordinated Units or other partnership securities proposed to be sold by GP LLC or any of its affiliates or their assignees if an exemption from the registration requirements is not otherwise available. These registration rights continue for two years following any withdrawal or removal of GP LLC as the Issuer’s general partner.

     On April 6, 2006, the Issuer entered into a Purchase and Sale Agreement (the “Initial Purchase Agreement”) with WES, Williams Field Services Group, LLC (“WFSG”), Williams Field Services Company, LLC (“WFSC”), GP LLC and Williams Partners Operating LLC, the operating subsidiary of the Issuer (“Williams OLLC”). Pursuant to the Initial Purchase Agreement, WES, WFSG, WFSC and GP LLC agreed to contribute to the Issuer a 25.1% membership interest (the “Initial Four Corners Interest”) in Williams Four Corners LLC (“Four Corners”) for aggregate consideration of $360.0 million. The following description of the Initial Purchase Agreement is qualified in its entirety by reference to the Initial Purchase Agreement filed as Exhibit 2.1 to the Issuer’s current report on Form 8-K (File No. 001-32599) filed with the Commission on April 7, 2006 which is incorporated in its entirety in this Item 4.

     In accordance with the Initial Purchase Agreement, on June 20, 2006, the Partnership, Williams OLLC, WES, WFSG, WFSC and GP LLC entered into a Contribution, Conveyance and Assumption Agreement (the “Contribution Agreement”) pursuant to which WES, WFSG, WFSC and GP LLC contributed the Initial Four Corners Interest to the Issuer in exchange for aggregate consideration of approximately $360.0 million. On June 20, 2006 and prior to the closing of the transactions contemplated by the Contribution Agreement, WFSC contributed to Four Corners its natural gas gathering, processing and treating assets in the San Juan Basin in New Mexico and Colorado. The foregoing description of the Contribution Agreement is qualified in its entirety by reference to the Contribution Agreement filed as Exhibit 10.1 to the Issuer’s current report on Form 8-K (File No. 001-32599) filed with the Commission on June 20, 2006 which is incorporated in its entirety in this Item 4.

     On June 20, 2006, the Issuer also closed a public offering of 7,590,000 Common Units at a public offering price of $31.25 per Common Unit and a private placement of $150 million aggregate principal amount of 7¹/2% Senior Notes due 2011. A portion of the net proceeds of these offerings were used to pay the purchase price for the Initial Four Corners Interest. The offerings and the acquisition of the Initial Four Corners Interest materially increased the capitalization of the Issuer.

     On November 16, 2006, the Issuer entered into a Purchase and Sale Agreement (the “Subsequent Purchase Agreement”) with WES, WFSG, WFSC, GP LLC and Williams OLLC. Pursuant to the Subsequent Purchase Agreement, WES, WFSG, WFSC and GP LLC agreed to contribute to the Issuer the remaining 74.9% membership interest in Four Corners that the Issuer did not already own (the “Remaining Four Corners Interest”) for aggregate consideration of $1.223 billion, subject to possible adjustment in favor of the Issuer. The foregoing description of the Subsequent Purchase Agreement is qualified in its entirety by reference to the Subsequent Purchase Agreement filed as Exhibit 2.1 to the Issuer’s current report on Form 8-K (File No. 001-32599) filed with the Commission on November 21, 2006 which is incorporated in its entirety in this Item 4.

      In accordance with the Subsequent Purchase Agreement, on December 13, 2006, the Partnership, Williams OLLC, WES, WFSC, WFSG and GP LLC entered into a Contribution, Conveyance and Assumption Agreement pursuant to which WES, WFSG, WFSC and GP LLC contributed the Remaining Four Corners Interest in exchange for aggregate consideration of $1.223 billion.

      On December 13, 2006, the Issuer also closed (i) a public offering of 8,050,000 Common Units at a public offering price of $38.00 per Common Unit, (ii) a private placement of $600 million aggregate principal amount of 7¹/4% Senior Notes due 2017 and (iii) a private placement of 2,905,030 Common Units and 6,805,492 Class B units representing limited partner interest in the Issuer (“Class B Units”) at a negotiated purchase price of $36.59 per Common Unit and $35.81 per Class B Unit. The net proceeds from these offerings were used to pay the purchase price for the Remaining Four Corners Interest. These offerings and the acquisition materially increased the capitalization of the Issuer. The Class B units converted into Common Units on a one-for-one basis on May 21, 2007 upon the approval of the Issuer’s common unitholders.

     On November 30, 2007, the Issuer entered into a Purchase and Sale Agreement (the “Wamsutter Purchase Agreement”) with WES, WFSG, WFSC, GP LLC and Williams OLLC. Pursuant to the Wamsutter Purchase Agreement, WES, WFSG, WFSC and GP LLC agreed to contribute to the Issuer 100% of the Class A limited liability company membership interests and 50% of the initial Class C units representing limited liability company membership interests (the “Wamsutter Interest”) in Wamsutter for aggregate consideration of $750.0 million. The following description of the Wamsutter Purchase Agreement is qualified in its entirety by reference to the Wamsutter Purchase Agreement filed as Exhibit 2.1 to the Issuer’s current report on Form 8-K (File No. 001-32599) filed with the Commission on December 3, 2007 which is incorporated in its entirety in this Item 4.

     In accordance with the Wamsutter Purchase Agreement, on December 11, 2007, WFSC and Wamsutter entered into an Assignment Agreement (the “Assignment Agreement”) pursuant to which WFSC transferred an approximate 1,700-mile natural gas gathering system, including a natural gas processing plant, located in the Washakie Basin in Wyoming to Wamsutter. The foregoing description of the Assignment Agreement is qualified in its entirety by reference to the Assignment Agreement filed as Exhibit 10.1 to the Issuer’s current report on Form 8-K (File No. 001-32599) filed with the Commission on December 17, 2007 which is incorporated in its entirety in this Item 4.

     In accordance with the Wamsutter Purchase Agreement, on December 11, 2007, the Partnership, Williams OLLC, WES, WFSG, WFSC and GP LLC entered into a Contribution, Conveyance and Assumption Agreement (the “Wamsutter Contribution Agreement”) pursuant to which WES, WFSG, WFSC and GP LLC contributed the Wamsutter Interest to the Issuer in exchange for aggregate consideration of $750.0 million. The foregoing description of the Wamsutter Contribution Agreement is qualified in its entirety by reference to the Wamsutter Contribution Agreement filed as Exhibit 10.2 to the Issuer’s current report on Form 8-K (File No. 001-32599) filed with the Commission on December 17, 2007 which is incorporated in its entirety in this Item 4.

     On December 11, 2007, the Issuer also closed a public offering of 9,250,000 common units at a public offering price of $37.75 per common unit. The Issuer used the net proceeds from this offering to pay $333.3 million of the $750 million aggregate consideration to acquire the Wamsutter Interest and to pay approximately $1.9 million of estimated expenses associated with the offering and the acquisition of the Wamsutter Interest. The Issuer financed the remainder of the aggregate consideration through (i) $250 million of term loan borrowings less associated transactions costs under the Issuer’s $450 million revolving credit facility, (ii) the issuance of 4,163,527 unregistered common units to GP LLC and (iii) the increase in GP LLC’s capital account in the amount of approximately $10.3 million to allow it to maintain its 2% general partner interest in GP LLC.

     The public offering and the issuance of unregistered common units to GP LLC have materially increased the capitalization of the Issuer.

     The Issuer may from time to time increase the amount of its quarterly distribution to unitholders at the discretion of the board of directors of GP LLC. The information provided under the caption “Issuer’s Partnership Agreement-Cash Distributions” under Item 6 below is hereby incorporated by reference herein.

     The information previously provided in response to this Item 6 is hereby amended by replacing the text thereof in its entirety with the following:

     The information provided or incorporated by reference in Item 3 and Item 4 is hereby incorporated by reference herein.

Omnibus Agreement

     Under the terms of an Omnibus Agreement, dated August 23, 2005, entered into among the Issuer, GP LLC, WES, WE, Williams Pipeline, Holdings, Williams OLLC and (for purposes of Articles V and VI thereof only) TWC (the “Omnibus Agreement”):

	•		GP LLC will provide the Issuer with a five-year partial credit for general and administrative, or G&A, expenses incurred on the Issuer’s behalf. For 2005, the amount of this credit was $3.9 million on an annualized basis but will be pro rated from the closing of the Issuer’s initial public offering (the “Offering”) through the end of 2005. Beginning in 2006, the amount of the G&A credit was $3.2 million, and the amount of the credit decreases by $800,000 for each subsequent year. As a result, after 2009, the Issuer will no longer receive any credit and will be required to reimburse GP LLC for all of the G&A expenses incurred on the Issuer’s behalf.
	•		Holdings, WES, WE and Williams Pipeline (collectively, the “Williams Indemnitors”) will indemnify the Issuer against certain environmental and related liabilities arising out of or associated with the operation of the assets before the closing date of the Offering. These liabilities include both known and unknown environmental and related liabilities, including: (i) remediation costs associated with the KDHE Consent Orders and certain fugitive natural gas liquids associated with the Issuer’s Conway storage facilities; (ii) the costs associated with the installation of wellhead control equipment and well meters at the Issuer’s Conway storage facility; (iii) KDHE-related cavern compliance at the Issuer’s Conway storage facility; and (iv) the costs relating to the restoration of the overburden along the Issuer’s Carbonate Trend pipeline in connection with erosion caused by Hurricane Ivan in September 2004. The Williams Indemnitors will not be required to indemnify the Issuer for any project management or monitoring costs. This indemnification obligation will terminate three years after the closing of the Offering, except in the case of the remediation costs associated with the KDHE Consent Orders which will survive for an unlimited period of time. There is an aggregate cap of $14.0 million on the amount of indemnity coverage, including any amounts recoverable under the Issuer’s insurance policy covering those remediation costs and unknown claims at Conway. In addition, the Issuer is not entitled to indemnification until the aggregate amounts of claims exceed $250,000. Liabilities resulting from a change of law after the closing of the Offering are excluded from the environmental indemnity by the Williams Indemnitors for the unknown environmental liabilities.
	•		The Williams Indemnitors will also indemnify the Issuer for liabilities related to:

Issuer’s Partnership Agreement

     GP LLC, as the sole general partner of the Issuer, and WE, WES, Williams Pipeline and Holdings, as limited partners of the Issuer, and all other limited partners of the Issuer are party to the Partnership Agreement.

Cash Distributions

     Pursuant to the terms of the Issuer’s Partnership Agreement, the Issuer intends to make minimum quarterly distributions of $0.35 per unit per quarter, or $1.40 per unit on an annualized basis, if the Issuer has sufficient cash from its operations after the establishment of cash reserves and payment of fees and expenses, including payments to GP LLC in reimbursement for all expenses incurred by it on the Issuer’s behalf. In general, the Issuer will pay any cash distributions made each quarter to its unitholders in the following manner:

     first, 98% to the common unitholders, pro rata, and 2% to GP LLC, until each outstanding common unit has received the minimum quarterly distribution for that quarter;

     second, 98% to the common unitholders, pro rata, and 2% to GP LLC, until each outstanding common unit has received any arrearages in payment of the minimum quarterly distribution for any prior quarters during the subordinated period;

     third, 98% to the subordinated unitholders, pro rata, and 2% to GP LLC, until each outstanding subordinated unit has received the minimum quarterly distribution for that quarter;

     fourth, 98% to the common unitholders, pro rata, and 2% to GP LLC, until each unitholder has received an amount equal to the excess of $0.4025 over the minimum quarterly distribution for that quarter;

     fifth, 98% to the subordinated units, pro rata, and 2% to GP LLC, until each subordinated unit has received the minimum quarterly distribution for that quarter; and

     sixth, 98% to all unitholders, pro rata, and 2% to GP LLC, until each unitholder has received a distribution of $0.4025 per unit for that quarter.

     If cash distributions per unit exceed $0.4025 in any quarter, GP LLC will receive increasing percentages, up to a maximum of 50%, of the cash distributed in excess of that amount. These distributions are referred to as “incentive distributions.”

Conversion of Subordinated Units

     Pursuant the terms of the Partnership Agreement, in any quarter during the subordination period (the period Subordinated Units are outstanding), the Subordinated Units are entitled to receive the minimum quarterly distribution of $0.35 only after the Common Units have received the minimum quarterly distribution and any arrearages in the payment of the minimum quarterly distribution from prior quarters. Subordinated Units will not accrue distribution arrearages. The subordination period will end once the Issuer meets certain financial tests set forth in the Partnership Agreement. These financial tests require, among other things, that the Issuer either (a) have earned and paid the minimum quarterly distribution and arrearages (if any) on all of its outstanding units for any three consecutive, non-overlapping four-quarter periods or (b) have earned and paid an amount that equals or exceeds 150% of the annualized minimum quarterly distribution on each outstanding unit for any four-quarter period. When the subordination period ends, all remaining Subordinated Units will convert into Common Units on a one-for-one basis, and the Common Units will no longer be entitled to arrearages.

Limited Call Right

     Pursuant to the Partnership Agreement, if at any time GP LLC and its affiliates hold more than 80% of the then-issued and outstanding partnership securities of any class, GP LLC will have the right, but not the obligation, which it may assign in whole or in part to any of its affiliates or to the Issuer, to acquire all, but not less than all, of the remaining partnership securities of the class held by unaffiliated persons as of a record date to be selected by GP LLC, on at least 10 but not more than 60 days notice. The purchase price in the event of this purchase is the greater of: (i) the highest price paid by either of GP LLC or any of its affiliates for any partnership securities of the class purchased within the 90 days preceding the date on which GP LLC first mails notice of its election to purchase those partnership securities; and (ii) the current market price as of the date three days before the date the notice is mailed.

Voting Rights

     The Partnership Agreement sets forth the voting rights of the partners of the Issuer (including WES, WE, Williams Pipeline, Holdings and GP LLC), including, among others, those for the removal of GP LLC as the Issuer’s general partner, the transfer of the general partner interest in the Issuer and the transfer of the incentive distribution rights in the Partnership.

Registration Rights

     Under the Partnership Agreement, the Issuer has agreed to register for resale under the Securities Act and applicable state securities laws any Common Units, Subordinated Units, Class B Units or other partnership securities proposed to be sold by GP LLC or any of its affiliates or their assignees if an exemption from the registration requirements is not otherwise available. These registration rights continue for two years following any withdrawal or removal of GP LLC as the Issuer’s general partner. The Issuer is obligated to pay all expenses incidental to the registration, excluding underwriting discounts and commissions.

Amended and Restated Limited Liability Company Agreement of GP LLC

     Under the Amended and Restated Limited Liability Company Agreement of GP LLC, WES has the right to elect the members of the board of directors of GP LLC.

Redemption Agreement

     The Issuer entered into a Common Unit Redemption Agreement, dated December 11, 2007 (the “Redemption Agreement”), with GP LLC. Pursuant to the Redemption Agreement, the Issuer agreed to redeem from GP LLC a number of common units equal to the number of common units that may be sold by the Issuer to the underwriters (the “Underwriters”) named in the underwriting agreement, dated December 5, 2007, by and among GP LLC, Williams OLLC and the Underwriters if the Underwriters exercise, in whole or in part, their 30-day option to purchase up to an additional 1,387,500 common units pursuant to the Underwriting Agreement. If the Underwriters do not exercise the Option, then no redemption will occur pursuant to the Redemption Agreement.

     To the Reporting Persons’ knowledge, there are no other contracts, arrangements, understandings or relationships (legal or otherwise) among the persons named in Item 2 and between such persons and any person with respect to any securities of the Issuer.
