Executive Services. Executive agrees to continue to perform his services as General Counsel until January 2, 2003 or such earlier time as may be determined by the Company in its sole and absolute discretion. It is expressly recognized by the parties hereto that Executive will continue to be employed by the Company as an "at will" employee and that the Company may terminate his services at any time with or without any reason. During his employment, Executive shall receive his current salary and except as otherwise provided in this Agreement, he shall be entitled to continue to participate in those employee benefit programs currently made available to him, unless such employee benefit programs are amended or terminated in accordance with their respective terms. The termination of Executive's employment prior to January 2, 2003 shall not in any way relieve Executive of any of his obligations hereunder including, but not limited to, his duty to provide consulting services and to provide a written release to the Company in accordance with the terms hereof. 2 2. Company Payments. On, or within ten (10) days of the date on which the Release Agreement set forth in Exhibit "B" becomes effective in accordance with its terms, the Company shall, in consideration of Executive's covenants and obligations hereunder: (i) Grant Executive's request to receive and apply his entire benefit with respect to the SERP, having a total value of Two Million, One Hundred Ninety-three Thousand, One Hundred and Thirty-two Dollars ($2,193,132.00), less all amounts required to be withheld under applicable federal and state tax laws, as an offset to his stock option loan; (ii) Pay Executive the sum of Three Hundred Thousand Dollars ($300,000.00), less all amounts required to be withheld under applicable federal and state tax laws, as a retention payment, provided the Company shall be entitled to apply the net amount due (after applicable tax withholdings) as a loan offset; (iii) Pay Executive, in connection with his retirement on the Separation Date pursuant to this Agreement, the sum of Five Hundred and Seventy-one Thousand Dollars ($571,000.00), less all amounts required to be withheld under applicable federal and state tax laws, as a severance payment in lieu of any and all severance payments, that may be owed to the Executive, provided the Company shall be entitled to apply 3 the net amount due (after applicable tax withholdings) as a loan offset; and (iv) Pay Executive the sum of Two Hundred Fifty Thousand Dollars ($250,000.00), less all amounts required to be withheld under applicable federal and state tax laws, for agreeing to not compete, executing the Consulting Agreement set forth on Exhibit "A", and agreeing not to solicit employees, provided the Company shall be entitled to apply the net amount due (after applicable tax withholdings) as a loan offset. Unless Executive has repaid his stock option loan, the Company shall not be required to deliver any funds to Executive in order to satisfy its obligations under this Paragraph 2. The Company's obligation with respect to such payments shall be limited to: (i) withholding and remitting to the appropriate governmental agency the minimum withholding amounts required under applicable federal and state laws and regulations and (ii) applying the remaining amount of such payments as an offset to repay the Executive's stock option loan until such loan is discharged in full with the balance of the payments, if any, being remitted to Executive. If the payments hereunder are not sufficient to repay such loan, Executive shall repay the remaining indebtedness of such loan within thirty (30) days after Executive's termination of employment, and, upon such payment, Company shall release the existing collateral for the loan. 4 3. SERP. The Executive hereby acknowledges and agrees that his SERP benefit is being paid to him at his request and that he will not be entitled to any further payments under the SERP. Executive hereby releases and forever discharges the SERP, the Company, its subsidiaries and affiliates (the "Williams Group") from any and all liabilities in connection with the SERP, including, but not limited to, any liability to provide any further payments to Executive. In addition, Executive hereby voluntarily waives any right which he may otherwise have to participate in the SERP and acknowledges and agrees that his release and waiver under this Paragraph 3 is part of the consideration for the agreement of the Company to permit his SERP benefit to be used as an offset to his loan obligation. 4. Severance. Due to the retention and severance payment being made hereunder, Executive also hereby voluntarily waives any right which he may have to receive severance payments (other than the payments provided hereunder) of any nature whatsoever from the Company, including but not limited to, the severance payments that are provided under any severance plans, practices, programs or agreements maintained by or contributed to by the Williams Group, including, but not limited to, any change-in-control severance plan or agreement. 5. Forfeiture of Deferred Stock Awards. Since the Executive's employment will cease on the Separation Date due to his voluntary retirement on January 2, 5 2003, Executive further acknowledges and agrees that all of his existing deferred stock awards that are scheduled to vest on or after January 2, 2003 will be forfeited unless such awards vest before that date pursuant to their existing terms. 6. Consulting.

Executive further understands that the execution of such Release is a material part of the consideration for the Company payments under Paragraph 2 hereof. 8. EICP Bonus. Executive may receive a bonus under the Executive Incentive Compensation Program for the 2002 calendar year. Such bonus, if any, will be determined by the Compensation Committee and will be based on a target opportunity of sixty-five percent (65%) of base pay, actual Company financial performance and, as determined by the Compensation Committee, stock performance and personal performance. The bonus, if any, will be paid, less all amounts required to be withheld under applicable federal and state tax laws, in a lump sum at the same time payment is made to other participants, 6 provided the Company shall be entitled to apply the net amount due (after applicable tax withholdings) as a loan offset. 9. Insurance and Indemnification. To the extent permitted by law and as provided in its Certificate of Incorporation and By-Laws, the Company shall use its best efforts to maintain directors and officers insurance providing coverage to Executive for, and shall indemnify and hold harmless Executive from, all claims made against him to the extent they relate to, or arise out of, his employment at the Company as a director, officer or employee. 10. Benefits. Except as otherwise provided in Paragraphs 3, 4 and 5 hereof, nothing contained herein shall be construed to abrogate Executive's rights under any employee benefit or incentive compensation plan. Executive's rights under any such employee benefit or incentive compensation plan shall be governed by the terms of such plan. 11. Confidentiality. Executive covenants and agrees that, during and for six (6) years after termination of Executive's employment with Company, Executive shall not, unless required by applicable law, divulge, furnish, disclose or make accessible to any person, entity or governmental authority any knowledge or information, techniques, processes, trade secrets, customer information or lists, plans, devices or material with respect to any secret, confidential or sensitive research or development work, promotions, ideas, opportunities, business plans, designs, products or production methods of the Williams Group or with respect to any other secret, confidential or sensitive aspect of the business of the Williams Group, except as may be necessary in the 7 furtherance and conduct of the business of the Williams Group. It is acknowledged that the Williams Group would be irreparably harmed if Executive should breach the provisions of this Paragraph 11. Accordingly, the Company is granted the right of specific performance to enforce the provisions of this Paragraph 11.

The 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. The 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. (b) Consultant shall not, solely by virtue of the consulting services provided hereunder, be considered to be an officer or employee of any member of the Williams Group during the Consulting Period, and shall not have the power or authority to contract in the name of or bind any member of the Williams Group.

Confidential Information. The 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 the Williams Group or (ii) other technical, business, proprietary or financial information of the Williams Group not available to the public generally or to the competitors of the Williams Group ("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 the Consultant, (b) is required to be disclosed by any law, regulation or order of any court or regulatory commission, department or agency, provided that the 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 the Consultant's duties under this Agreement. 3 Promptly following the termination of the Consulting Period, the 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.

(e) If, at any time of enforcement of this Paragraph 4, a court or an arbitrator 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 or arbitrator 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 or arbitrator 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 performance of this Agreement. 6.

The Consultant may only terminate this Agreement due to a material breach hereof by Williams. 7. Termination of 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 which were released or waived by Consultant pursuant to the Settlement and Retention Agreement dated August 7, 2002. 8. Enforcement. The parties hereto agree that the Williams Group 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. Accordingly, Williams and its successors and permitted assigns shall be entitled, in addition to other rights and remedies existing in their favor, to an injunction or injunctions to prevent any breach or threatened breach of any of such provisions and to enforce such provisions specifically (without posting a bond or other security). The Consultant agrees that he will submit himself to the personal jurisdiction of the courts of the State of Oklahoma in any action by Williams to enforce an arbitration award against him or to obtain interim injunctive or other relief pending an arbitration decision. 9. Disputes. Any controversy or claim arising out of or relating to this Agreement, or any breach thereof, shall be settled by arbitration in accordance with the 6 rules of the American Arbitration Association then in effect in the State of Oklahoma, and judgment upon such award rendered by the arbitrator(s) may be entered in any court having jurisdiction thereof. The arbitration shall be held in Tulsa, Oklahoma, each party to bear its own costs. The arbitrator shall have the authority to award any remedy or relief that a court of competent jurisdiction could order or grant, including, without limitation, the issuance of an injunction. However, either party may, without inconsistency with this arbitration provision, apply to any court having jurisdiction over such dispute or controversy and seek interim provisional, injunctive or other equitable relief until the arbitration award is rendered or the controversy is otherwise resolved.
