     THIS CONSULTING AGREEMENT is entered into this 2nd day of April, 2008, by and between THE WILLIAMS COMPANIES, INC. a Delaware Corporation, (“Williams” or the “Company”) and Michael P. Johnson (“Consultant”).

     WHEREAS, Williams wishes to avail itself of Consultant’s knowledge, expertise and experience by utilizing the services of Consultant; and

     WHEREAS, Consultant is willing to serve as a consultant to Williams upon the terms and conditions set forth below;

     NOW, THEREFORE, in consideration of their mutual promises and for other good and valuable consideration, Williams and Consultant hereby agree as follows:

     1. Consulting Services.

     (a) During the period beginning on the date on which Consultant ceases to be employed by Williams and continuing through December 31, 2008 (the “Consulting Period”), Consultant shall provide to Williams, including its subsidiaries and affiliates, consulting services commensurate with his status and experience as Williams’ Senior Vice President and Chief Administrative Officer to enable a smooth transition of his duties to his successor with respect to such matters as shall be reasonably requested from time to time by the Chief Executive Officer of Williams (the “Williams Representative”), provided that Consultant shall not be required to provide such services during any period when he is unable to perform due to his health.

     (b) Consultant shall provide consulting services to Williams only as needed and when reasonably requested by the Williams Representative, provided that, without his prior consent, Consultant shall not be required to devote more than eighty (80) hours in any calendar month to the performance of any consulting services hereunder. Consultant agrees that in the event it becomes necessary for him to devote more than eighty (80) hours in any calendar month to performing services under this Agreement, Consultant will obtain approval from Williams’ Chief Executive Officer and the Executive Officer Team member for whom the services are being provided prior to providing such services. Consultant shall determine the time and location at which he shall perform such services, subject to the right of the Williams Representative to reasonably request by advance written notice that such services be performed at a specific time and at a specific location. Consultant shall honor any such request unless he is unable to perform due to his health, or he has a conflicting business commitment that

would preclude him from performing such services at the time and/or place requested by the Williams Representative, and in such circumstances, shall make reasonable efforts to arrange a mutually satisfactory alternative. Williams shall use its reasonable best efforts not to require the performance of consulting services in any manner that unreasonably interferes with any other business activity of Consultant.

     (c) Consultant shall not, solely by virtue of the consulting services provided hereunder, be considered to be an officer or employee of any member of Williams during the Consulting Period, and shall not have the power or authority to contract in the name of or bind any member of Williams. Consultant shall at all times be treated as an independent contractor and shall be responsible for the payment of all taxes with respect to all amounts paid to him hereunder. Consultant shall not, by reason of the services performed hereunder, be entitled to participate in any employee benefits plan, program or arrangement made available to any employee of Williams.

     (d) This Agreement is personal to Consultant and all of the services required of Consultant hereunder shall be performed personally by him.

     2. Consulting Fees. In accordance with its normal pay cycle, but not before the eighth (8^th) day following Consultant’s execution of this Agreement, Williams shall pay Consultant the sum of Two Hundred Sixty Three Thousand Seven Hundred Fifty Eight Dollars ($263,758.00) (“Consulting Fee”) as consideration for executing this Agreement and providing the services set forth hereunder. Consultant shall not be entitled to receive any other compensation, bonuses or benefits provided to Williams’ employees in exchange for the services provided by Consultant under the terms of this Agreement. However, Williams will reimburse Consultant for reasonable and necessary travel expenses, including costs for transportation, meals and lodging that Consultant may incur in connection with his performance of services under this Agreement. During the Consulting Period, Consultant may also utilize Williams’ corporate aircraft for travel necessary to his performance of services under this Agreement, subject to the approval of the Williams Representative and the availability of the aircraft.

     3. Confidential Information. Consultant shall not, at any time during the Consulting Period, make use of or disclose, directly or indirectly, any (i) trade secret or other confidential or

secret information of Williams or (ii) other technical, business, proprietary or financial information of Williams not available to the public generally or to the competitors of Williams (“Confidential Information”), except to the extent that such Confidential Information (a) becomes a matter of public record or is published in a newspaper, magazine or other periodical available to the general public, other than as a result of any act or omission of Consultant, (b) is required to be disclosed by any law, regulation or order of any court or regulatory commission, department or agency, provided that Consultant gives prompt notice of such requirement to Williams to enable Williams to seek an appropriate protective order, or (c) is necessary to perform properly Consultant’s duties under this Agreement. Promptly following the termination of the Consulting Period, Consultant shall surrender to Williams all records, memoranda, notes, plans, reports, computer tapes and software and other documents and data which constitute Confidential Information which he may then possess or have under his control (together with all copies thereof).

     4. Exclusive Services/Non-solicitation.

     (a) Consultant acknowledges that during the Consulting Period he will become familiar with trade secrets and other confidential information concerning Williams and that his services will be of special, unique and extraordinary value to Williams.

     (b) Consultant agrees that during the Consulting Period he shall not in any manner, directly or indirectly, through any person, firm or corporation, alone or as a member of a partnership or as an officer, director, stockholder, investor or employee of or consultant to any other corporation or enterprise or otherwise, engage or be engaged, or assist any other person, firm corporation or enterprise in engaging or being engaged, in

any business, in which Consultant was involved or of which he has knowledge is being conducted by Williams during the Consulting Period. Notwithstanding the provisions of this subparagraph 4(b) to the contrary, Consultant may act as a director, stockholder, investor or employee of or consultant to any corporation or enterprise with regard to the business or businesses referred to above with the prior written consent of Williams, such consent not to be unreasonably withheld.

     (c) Consultant further agrees that during the Consulting Period he shall not in any manner, directly or indirectly, induce or attempt to induce any employee Williams to terminate or abandon his or her employment for any purpose whatsoever.

     (d) Nothing in this Paragraph 4 shall prohibit Consultant from being (i) a stockholder in a mutual fund or a diversified investment company or (ii) a passive owner of not more than two percent (2%) of the outstanding stock of any class of a corporation, or any securities of which are publicly traded, so long as Consultant has no active participation in the business of such corporation.

     (e) If, at any time of enforcement of this Paragraph 4, a court holds that the restrictions stated herein are unreasonable under circumstances then existing, the parties hereto agree that the maximum period, scope or geographical area reasonable under such circumstances shall be substituted for the stated period, scope or area and that the court shall be allowed to revise the restrictions contained herein to cover the maximum period, scope and area permitted by law. This Agreement shall not authorize a court to increase or broaden any of the restrictions in this Paragraph.

     5. Hold Harmless. Consultant shall hold harmless Williams, its subsidiaries and affiliates, and its and their respective shareholders, officers, directors, employees and attorneys

against any damage, injury, death, claim, loss, charge or expense (including, without limitation, attorneys’ fees and court costs and the costs of investigation) of any party, including Consultant, arising out of or relating to, or claimed to arise out of or relate to, Consultant’s gross negligence or willful misconduct in performing under this Agreement.

     6. No Tax Advice. Consultant agrees and acknowledges that Williams has made no representations to him regarding the tax consequences of the money paid pursuant to this Agreement, and that he shall rely upon his own tax advice with respect to any taxes owed on any of such monies.

     7. Termination of the Consulting Services. Williams may terminate this Agreement at any time prior to December 31, 2008, but the parties agree and acknowledge that Williams shall only be entitled to a pro-rata refund of the Consulting Fee in the event that the Agreement is terminated solely for cause, which shall be limited to either (i) the conviction of Consultant of a felony which has a substantial effect on Williams’ business or reputation, or (ii) the continual and repeated failure of Consultant to perform the services required of him hereunder, after written notice of the alleged failures and an opportunity to cure has been given. Consultant may only terminate this Agreement due to a material breach hereof by Williams.

     8. No Waiver of Vested Benefits. Nothing in this Agreement shall be construed to limit, reduce, offset or otherwise impair Consultant’s rights to any benefits or compensation vested or accrued under the terms of the employee benefit plans, programs or arrangements maintained by Williams other than those benefits that were released or waived by Consultant pursuant to the Confidential Separation Agreement and Release dated April 2, 2008.

     9. Computer/Office Support and Access.

     10. Enforcement. The parties hereto agree that Williams would be damaged irreparably in the event that any provision of Paragraph 3 or 4 of this Agreement were not performed in accordance with its terms or were otherwise breached and that money damages would be an inadequate remedy for any such nonperformance or breach.
