If there are no sales on any one of those days of that twenty-day period, the average of the closing bid and asked prices for that day, as reported in the principal composite reporting system for the NYSE, will be used). Such New Units would have the rights and obligations specified in the Amended and Restated Agreement of Limited Partnership of Energy Partners as further amended by the First Amendment thereto dated as of the Closing Date. The term "WES Equity Amount" means $1,000,000,000 minus the sum of (i) the Net Cash Proceeds and (ii) 2 the amount of $15,036,000 for the "NFL trade notes and accounts receivable reflected in Part V of Exhibit 1.1 and assigned to WES before Closing); and (C) an additional General Partner Interest in Energy Partners equal to 2% of the WES Equity Amount in satisfaction of Williams GP LLC's obligation, in connection with the transaction contemplated by this Agreement, to contribute 2% of total contributions to Energy Partners in accordance with the terms of Energy Partners' Amended and Restated Agreement of Limited Partnership; and. (d) In accordance with clause (c)(1) above, Energy Partners will borrow the necessary funds and distribute the Borrowing Proceeds to Williams GP LLC in satisfaction of GP LLC's right to receive such amount as set forth in clause (c)(1)(A) above. 2.3 Transfer Taxes and Recording Fees (a) WES and Williams GP LLC, as contributors hereunder, will each be responsible for any and all taxes or fees imposed or incurred by reason of the contributions hereunder and/or the filing or recording of any instruments necessary to effect the contributions hereunder, regardless of when such taxes or fees are levied or imposed. 2.4 Working Capital The term "WPL Working Capital" means the adjusted net working capital working capital of WPL which excludes the receivables, intercompany amounts and other items specified by, and calculated a~ set forth, in Schedule 2.4 hereto. "Historical WPL Working Capital" means the average of the adjusted net working capital WPL Working Capital amounts for the six months of September - December, 2001 and January and February, 2002, as shown on Schedule 2.4. As soon after Closing as is practicable (but not later than June 30, 2002), the Historical WPL Working Capital will be compared to WPL's Working Capital amount as of March 31, 2002.

Notwithstanding anything to the contrary herein, any franchise Tax paid or 27 payable with respect to WPL or a predecessor to WPL shall be allocated to the taxable period during which the income, operations, assets or capital comprising the base of such Tax is measured, regardless of whether the right to do business for another taxable period is obtained by the payment of such franchise Tax. (e) Energy Partners agrees to pay to WES any refund received after the Closing Date by it or its affiliates, including WPL, in respect of any Taxes for which WES is liable under clause (b) of this Section 7.1. WES agrees to pay to Energy Partners any refund received by WES or their affiliates in respect of any Taxes for which Williams GP LLC and Energy Partners is liable under clause (c) of this Section 7.1. The parties shall cooperate in order to take all steps reasonably necessary to claim any such refund. Any such refund received by a party or its affiliate for the account of the other party shall be paid to such other pasty within 90 days after such refund is received. (f) Williams GP LLC and Energy Partners and WES agree not to make or cause any election (including an election to ratably allocate items under Treasury Regulations Section 1.1502-76(b) (2) (ii)) to allocate tax items in a manner inconsistent with Section 7.1(d) hereof. 7.2 Tax Returns (a) WES shall cause to be included in the consolidated federal income Tax Returns (and the state income Tax Returns of any state that permits consolidated, combined or unitary income Tax Returns, if any) of the Williams Group (as defined herein) for all periods ending on or before the Closing Date, all Tax items of WPL which are required to be included therein, shall cause such Tax Returns to be timely filed with the appropriate Taxing Authorities, and shall be responsible for the timely payment (and entitled to any refund) of all Taxes due with respect to the periods covered by such Tax Returns. For purposes of this Agreement, "Williams Group" means the affiliated group of corporations within the meaning of section 1504 of the Internal Revenue Code of 1986, as amended, which files a consolidated federal income Tax Return and as to which The Williams Companies, Inc. is the common parent, and, in the case of any combined or unitary Tax Return, the group of corporations filing such Tax Return that includes WPL or its operations. (b) With respect to any Tax Return covering a taxable period ending on or before the Closing Date that is required to be filed after the Closing Date with respect to WPL that is not described in paragraph (a) above, WES shall cause such Tax Return to be prepared, shall cause to be included in such Tax Return all Tax items required to be included therein, shall cause such Tax Return to be filed timely with the appropriate Taxing Authority, and shall be responsible for the timely payment (and entitled to any refund) of all Taxes due with respect to the period covered by such Tax Return. 28 (c) With respect to any Tax Return covering a taxable period beginning on or before the Closing Date and ending after the Closing Date that is required to be filed after the Closing Date with respect to WPL, Energy Partners shall cause such Tax Return to be prepared, shall cause to be included in such Tax Return all Tax items required to be included therein, shall furnish a copy of such Tax Return to WES, shall file timely such Tax Return with the appropriate Taxing Authority, and shall be responsible for the timely payment of all Taxes due with respect to the period covered by such Tax Return. Energy Partners shall determine, in accordance with the provisions of Section 7.1(d) of the Agreement, the amount of Tax due with respect to the period prior to and including the Closing Date (the "Contributor's Tax") and shall notify WES of its determination of the Contributor's Tax. WES shall pay to Energy Partners an amount equal to the Contributor's Tax not later than five days after the filing of such Tax Return. Any refund attributable to Tax Returns filed pursuant to this Section 7.2(c) shall be apportioned between Energy Partners and WES in a manner consistent with calculation of the Contributor's Tax. (d) Energy Partners shall, with respect to any Tax Return for which Energy Partners is responsible under Section 7.2(c) for preparing and filing, make such Tax work papers available for review by WES if the Tax Return is with respect to Taxes for which WES may. be liable (in whole or in part) hereunder or under applicable law. Energy Partners shall make such work papers available for review sufficiently in advance of the due date for filing such Tax Returns to provide WES with a meaningful opportunity to analyze and comment on such Tax Returns and have such Tax Returns modified before filing, accepting the position of Energy Partners unless such position is contrary to the provisions of Section 7.2(e) hereof. (e) Any Tax Return which includes or is based on the operations, ownership, assets or activities of WPL for any taxable period beginning before and ending after the Closing Date, and any Tax Return in respect of any Taxes for which WES may be liable (in whole or in part) hereunder shall be prepared in accordance with past Tax accounting practices used with respect to the Tax Returns in question (unless such past practices are no longer permissible under the applicable law), and to the extent any items are not covered by past practices (or in the event such past practices are no longer permissible under the applicable tax law), in accordance with reasonable tax accounting practices selected by the filing party with respect to such Tax Return under this Agreement with the consent (not to be unreasonably withheld or delayed) of the non-filing party. Unless required by law, Energy Partners shall not file an amended Tax Return for any period ending on or prior to the Closing Date without the consent of WES. 29 7.3 Tax Proceedings If Energy Partners receives notice (the 'Proceeding Notice") of any examination, claim, adjustment, or other proceeding with respect to the liability of WPL for Taxes for any period for which WES is or may be liable under Section 7.1, Energy Partners shall notify WES in writing thereof (the "Energy Partners Notice") no later than the earlier of (a) thirty (30) days after the receipt by Energy Partners of the Proceeding Notice or (b) ten (10) days prior to the deadline for responding to the Proceeding Notice. Such Energy Partners Notice shall contain factual information describing any asserted liability for Taxes in reasonable detail and shall be accompanied by copies of any notice or other documents received from any Taxing Authority with respect to such matter. As to any such Taxes for which WES is or may be liable under Section 7.1, WES shall be entitled at its expense to control or settle the contest of such examination, claim, adjustment, or other proceeding, provided (a) WES notifies Energy Partners in writing that it desires to do so no later than the earlier of (1) thirty (30) days after receipt of the Energy Partners Notice or (2) five (5) days prior to the deadline for responding to the Proceeding Notice, and (b) WES may not, without the consent of Energy Partners, agree to any settlement which would result in an increase in the amount of Taxes for which any of Energy Partners or WPL or any of WPL's owners is or may be liable under Section 7.1. WES shall pay any Taxes required to be paid in connection with any examination, claim, adjustment or other proceeding, including, without limitation, any prepayment of Tax required to obtain the jurisdiction of a court. The parties shall cooperate with each other and with their respective affiliates, and shall consult with each other, in the negotiation and settlement of any proceeding described in this Section 7.3. WES shall pay to Energy Partners the amount of any Tax Losses Energy Partners may become entitled to by reason of the provisions of this Article 7 within fifteen (15) days after the extent of any Tax liability has been determined by a final judgment or decree of a Court or a final and binding settlement with a governmental authority having jurisdiction thereof. 7.4 Cooperation and Exchange of Information Williams GP LLC and Energy Partners and WES shall cooperate fully, and shall cause WPL to cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of Tax Returns pursuant to this Article 7 and any proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other party's request) the provision of records and information which are reasonably relevant to any such proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. WES, Williams GP LIC and Energy Partners agree to retain all books and records in their possession or in the possession of their respective affiliates with respect to Tax matters pertinent to WPL relating to any taxable period beginning before the Closing Date until the earlier of six years after the Closing Date and the expiration of the applicable statute of limitations of the respective taxable periods, and to abide by all record retention agreements entered 30 into with any Taxing Authority, and thereafter, upon request, allow Williams GP LLC and Energy Partners to take possession of such books and records. Each party shall provide the cooperation and information required by this Section 7.4 at its own expense. 7.5 Survival. Anything to the contrary in this Agreement notwithstanding, the representations, warranties, covenants, agreements, rights and obligations of the parties hereto with respect to any Tax matter covered by this Agreement shall survive the Closing and shall not terminate until thirty days after the expiration of the statute of limitations (including extensions) applicable to such Tax matter. 7.6 Conflict In the event of a conflict between the provisions of this Article 7 and any other provisions of this Agreement, the provisions of this Article 7 shall control. 7.7 Miscellaneous (a) Any payment required under this Article 7 and not made when due shall bear interest at the rate per annum determined, from time to time, under the provisions of Section 6621(a)(2) or 6621(c) of the Code, as applicable, for each day until paid.

Except for and without limitation of the scope and effect of the express representations, warranties, covenants and agreements contained herein, the parties HEREBY EXPRESSLY DISCLAIM AND NEGATE ANY OTHER REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, RELATING TO WPL AND ITS ASSETS AND OPERATIONS OR TO THE TRANSACTIONS CONTEMPLATED HEREBY, AS APPLICABLE (INCLUDING, WITHOUT LIMITATION, ANY IMPLIED OR EXPRESS WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE OR CONFORMITY TO MODELS OR SAMPLES OF MATERIALS). 31 ARTICLE 9 TERMINATION 9.1 Events of Termination This Agreement may be terminated at any time prior to the Closing Date: (a) by mutual written consent of the parties; (b) by either Energy Partners or WES in writing after May 31, 2002, if the Closing has not occurred by such date; (c) by either Energy Partners or WES in writing (provided the terminating party and its affiliates are not otherwise in material default or breach of this Agreement, or have not failed or refused to close without justification hereunder), if the other party (1) has materially failed to perform its covenants or agreements contained herein required to be performed on or prior to the Closing Date, or (2) has breached any of its representations or warranties contained herein; provided, however, that in the case of clause (1) or (2), the defaulting party shall have a period of ten (10) days following written notice from the nondefaulting party to cure any breach of this Agreement, if such breach is curable; (d) by either Energy Partners or WES in writing if there shall be any order, writ, injunction or decree of any Governmental Authority binding on any of the parties, which prohibits or restrains them from consummating the transactions contemplated hereby, provided that the parties shall have used their reasonable best efforts to have any such order, writ, injunction or decree lifted and the same shall not have been lifted within 30 days after entry by any such Governmental Authority; (e) by WES if any of the conditions set forth in Section 6.2 have become incapable of fulfillment, and, after 10 days following notice by WES, remain incapable of fulfillment and not waived by WES; or (1) by Williams GP LLC and Energy Partners if any of the conditions set forth in Section 6.1 have become incapable of fulfillment, after 10 days following notice by Energy Partners, remain incapable of fulfillment and not waived by Williams GP LLC and Energy Partners. 32 9.2 Effect of Termination If a party terminates this Agreement as provided in Section 9.1 above, termination shall be without liability and none of the provisions of this Agreement will remain effective or enforceable. ARTICLE 10 INDEMNIFICATION UPON CLOSING 10.1 Indemnification of Williams GP LLC and Energy Partners upon Closing Subject to the limitations set forth in this Agreement, WES, from and after the Closing, shall indemnify, defend and hold Williams GP LLC, in its capacity as general partner of Energy Partners, and Energy Partners and its subsidiaries, and their respective shareholders, members, partners, directors, officers, and employees (the "Energy Partners Parties") harmless from and against any and all liabilities and obligations, including without limitation, all losses, deficiencies, costs, expenses, fines, penalties, interest, expenditures, investigatory costs, cleanup and remediation costs, governmental response costs, claims, suits, proceedings, judgments, settlements, damages, and reasonable attorneys' fees and reasonable expenses of investigating, defending and prosecuting litigation (all of the foregoing of which are collectively referred to as the "Damages") suffered or incurred by the Energy Partners Parties as a result of or arising out of (a) any breach of a representation or warranty of WES in this Agreement, or any breach of any agreement or covenant on the part of WES made under this Agreement or in connection with the transaction contemplated hereby, (b) any breach of, failure to comply with or liability arising under any Environmental Laws with respect to the ownership, operation or conduct of the businesses or affairs of WPL before the Closing, or (c) the Excluded Assets or the ownership or operation thereof. Nothing in this Section 10.1 or in Section 10.8 shall apply to, or limit, liability with respect to Taxes, for which liability shall be as set forth in Article 7. 10.2 Indemnification of WES Subject to the limitations set forth in this Agreement, Energy Partners shall indemnify, defend and hold WES and its Affiliates (other than any of the Energy Partners Parties), and their respective shareholders, members, partners, directors, officers, and employees (together with WES, the "WES Parties") harmless from and against any and all Damages suffered or incurred by the WES Parties as a result of or arising out of (a) any breach of a representation or warranty of Energy Partners in this Agreement and any breach of any agreement or covenant on the part of Energy Partners made under. this Agreement or in connection with the transaction contemplated hereby, (b) any breach of, failure to comply with or liability arising under any Environmental Laws with respect to the ownership, operation or conduct of the businesses or affairs of WPL on or after the Closing, or (c) the ownership, operation or conduct of the business or affairs of WPL on or after the Closing. 33 Nothing in this Section 10.2 or in Section 10.8 shall apply to, or limit, liability with respect to Taxes, for which liability shall be as set forth in Article 7. 10.3 Demands Each indemnified party hereunder agrees that promptly upon its discovery of facts giving rise to a claim for indemnity under the provisions of this Agreement, including receipt by it of notice of any demand, assertion, claim, action or proceeding, judicial or otherwise, by any third party (such claims for indemnity involving third party claims being collectively referred to herein as the "Indemnity Claim"), with respect to any matter as to which it claims to be entitled to indemnity under the provisions of this Agreement, it will give notice thereof in writing to the indemnifying party, together with a statement of such information respecting any of the foregoing as it shall have. Such notice shall include a formal demand for indemnification under this Agreement. If the indemnified party knowingly fails to notify the indemnifying party thereof in accordance with the provisions of this Agreement in sufficient time to permit the indemnifying party or its counsel to defend against an Indemnity Claim and to make a timely response thereto, the indemnifying party's indemnity obligation relating to such Indemnity Claim shall be limited to the extent that such failure has actually prejudiced or damaged the indemnifying party with respect to that Indemnity Claim. 10.4 Right to Contest and Defend The indemnifying party shall be entitled, at its cost and expense, to contest and defend by all appropriate legal proceedings any Indemnity Claim for which it is called upon to indemnify the indemnified party under the provisions of this Agreement; provided, that notice of the intention to so contest shall be delivered by the indemnifying party to the indemnified party within 20 days from the date of receipt by the indemnifying party of notice by the indemnified party of the assertion of the Indemnity Claim. Any such contest may be conducted in the name and on behalf of the indemnifying party or the indemnified party as may be appropriate. Such contest shall be conducted by reputable counsel employed by the indemnifying party and not reasonably objected to by the indemnified party, but the indemnified party shall have the right but not the obligation to participate in such proceedings and to be represented by counsel of its own choosing at its sole cost and expense. The indemnifying party shall have full authority to determine all action to be taken with respect to any Indemnity Claim; provided, however, that the indemnifying party will not have the authority to subject the indemnified party to any obligation whatsoever, other than the performance of purely ministerial tasks. If the indemnifying party does not elect to contest any such Indemnity Claim, the indemnifying party shall be bound by the result obtained with respect thereto by the indemnified party. If the indemnifying party assumes the defense of an Indemnity Claim, the indemnified party shall agree to any settlement, compromise or 34 discharge of an Indemnity Claim that the indemnifying party may recommend and that by its terms obligates the indemnifying party to pay the full amount of the liability in connection with such Indemnity Claim, which releases the indemnified party completely in connection with such Indemnity Claim and which would not otherwise adversely affect the indemnified party. Notwithstanding the foregoing, the indemnifying party shall not be entitled to assume the defense of any Indemnity Claim (and shall be liable for the reasonable fees and expenses of counsel incurred by the indemnified party in defending such Indemnity Claim) if the Indemnity Claim seeks an order, injunction or other equitable relief or relief for other than money damages against the indemnified party which the indemnified party reasonably determines, after conferring with its outside counsel, cannot be separated from any related claim for money damages. If such equitable relief or other relief portion of the Indemnity Claim can be so separated from that for money damages, the indemnifying party shall be entitled to assume the defense of the portion relating to money damages. 10.5 Cooperation If requested by the indemnifying party, the indemnified party agrees to cooperate with the indemnifying party and its counsel in contesting any Indemnity Claim that the indemnifying party elects to contest or, if appropriate, in making any counterclaim against the person asserting the Indemnity Claim, or any cross-complaint against any such person, and the indemnifying party will reimburse the indemnified party for any expenses incurred by it in so cooperating. At no cost or expense to the indemnified party, the indemnifying party shall cooperate with the indemnified party and its counsel in contesting any Indemnity Claim. 10.6 Right to Participate The indemnified party agrees to afford the indemnifying party and its counsel the opportunity to be present at, and to participate in, conferences with all persons, including Governmental Authorities, asserting any Indemnity Claim against the indemnified party or conferences with representatives of or counsel for such persons. 10.7 Payment of Damages The indemnification required hereunder shall be made by payments of the amount thereof during the course of the investigation or defense, within thirty (30) days as and when reasonably specific bills are received or loss, liability, claim, damage or expense is incurred and reasonable evidence thereof is delivered. In calculating any amount to be paid by an indemnifying party by reason of the provisions of this Agreement, the amount shall be reduced by all tax benefits and other reimbursements (including, without limitation, insurance proceeds) credited to or received by the indemnified party related to the Damages. 35 10.8 Limitations on Indemnification (a) WES' indemnity obligations under this Agreement will apply only to Damages which are sustained or incurred by the Energy Partners Parties for which notice in accordance with the provisions of this Agreement has been given within any applicable survival period for such indemnity obligations.

WES will have an option for a period of sixty (60) days from the date of its actual receipt of such notice to elect to purchase or acquire the assets, rights, ownership or other interests proposed to be Transferred for the same consideration and subject to the same material terms and conditions as described in Energy Partners' written notice of the proposed Transfer. Additionally, if the consideration identified in the notice is other than cash, WES will have the right to pay the purchase price in the form of cash equal in amount to the reasonable and justified value of such non-cash consideration.
