and New WCG shall not enter into any amendment, restatement, supplement or other
modification to the WCG Bank Facility or any other Loan Document which (a)
increases the outstanding principal amount of the Loans (as such term is defined
in the WCG Bank Facility) or (b) extends the Maturity Date (as such term is

paid in full in accordance with applicable provisions of the WCG Bank Facility.

         15. Shareholders Agreement. Seller, WAL, WAI and TWC (collectively, the
"TWC Parties") have requested that Purchaser, WCL and New WCG (the "WCG
Parties") cause CG Austria and/or WCP to obtain, and the WCG Parties hereby
agree to cause CG Austria and/or WCP to promptly endeavor to obtain, a waiver or
waivers in form and substance reasonably satisfactory to the TWC Parties
(individually or collectively, the "Waiver") of any actual or potential default
or event of default arising under or in connection with any actual or alleged
breach or violation of Section 7.09 of the Shareholders Agreement by WCP arising
solely in connection with any transaction or series of transactions as a result
of which WCP no longer remained a Subsidiary (as such term is defined in the
Shareholders Agreement) of Williams International Company (the "Shareholders
Agreement Default"), provided that any failure by CG Austria or WCP to obtain
the Waiver at any time following the date hereof and/or the existence and
continuance of the Shareholders Agreement Default shall not (x) constitute an
Event of Default (as such term is defined in the Purchase Money Mortgage) or (y)
constitute a default or event of default or other breach or violation of the
Pledge Agreement, the Equitable Mortgage or any other Loan Document (as such
term is defined in the Purchase Money Mortgage) and, provided further, that the
rights and remedies of any TWC Party against any WCG Party or WCP in respect of
any failure by WCP to obtain the Waiver or the Shareholders Agreement Default
shall be limited solely to the indemnification rights specified in this Section
15 and, provided further, in connection with the foregoing each TWC Party hereby
agrees to take all actions reasonably requested by any WCG Party (at the sole
cost and expense of such WCG Party) in furtherance of CG Austria's and/or WCP's
efforts to obtain the Waiver. Each WCG Party hereby jointly and severally agrees
to indemnify, reimburse and hold harmless each TWC Party and each of their
respective successors and assigns (hereinafter, an "Indemnitee" and collectively
the "Indemnitees"), to the fullest extent permitted by applicable law, from any
and all liabilities, obligations, damages, penalties, claims, demands, actions,
suits, judgments and any and all costs, expenses or disbursements (including
attorneys' fees and expenses reasonably incurred)

                                      -4-
<PAGE>

(collectively, the "Indemnified Liabilities") of whatsoever kind and nature
imposed on or reasonably incurred by any of the Indemnitees as a result of,
relating to or arising out of any actual or prospective claim, litigation or
other proceeding relating to or arising out of CG Austria's or WCP's failure to
obtain the Waiver or the Shareholders Agreement Default, provided that no such
Indemnitee shall be indemnified pursuant to this Section 15 for Indemnified
Liabilities to the extent any such Indemnified Liabilities are caused by the
gross negligence or willful misconduct of such Indemnitee (as determined by a
court of competent jurisdiction in a final non-appealable decision). Each WCG
Party acknowledges and agrees that upon receipt of written notice by any WCG
Party from any Indemnitee of the existence or assertion of an Indemnified
Liability, such WCG Party shall assume full responsibility for the defense
thereof. Any amount due under this Section 15 shall be payable by one or more of
the WCG Parties promptly upon and in any event within thirty (30) days after
receipt of written demand by any Indemnitee therefor. Each Indemnitee hereby
agrees to use reasonable efforts to promptly notify Purchaser of any actual or
potential Indemnified Liability of which such Indemnitee has notice or knowledge
and to specify in reasonable detail the nature of any such Indemnified
Liability. The obligations of each WCG Party and CG Austria under this Section
15 shall survive termination of the Agreement and shall remain in full force and
effect until: (1) CG Austria and/or WCP has obtained the Waiver and delivered a
copy thereof to each TWC Party, (2) the Shareholders Agreement is terminated by
mutual agreement of the parties thereto, (3) WCP ceases to be a party to the
Shareholders Agreement or (4) the occurrence of a Permitted Disposition (as such
term is defined in the Pledge Agreement).

         16. Foreign Investment Review Board ("FIRB") Approval. Pursuant to
Section 2 of the Pledge Agreement, the Pledge Agreement and the granting of the
pledge and security interests thereunder by CG Austria to Seller thereunder
shall not be effective and enforceable against CG Austria until Seller obtains
the FIRB Approval (as such term is defined in the Pledge Agreement). Each WCG
Party and TWC Party hereby agrees that, in the event that Seller is unable to
obtain the FIRB Approval, (a) such failure to obtain the FIRB Approval shall not
constitute (i) an Event of Default (as such term is defined in the Purchase
Money Mortgage) or (ii) a default or event of default or other breach or
violation of the Pledge Agreement, the Equitable Mortgage or any other Loan
Document (as such term is defined in the Purchase Money Mortgage); (b) each WCG
Party shall jointly and severally pay or reimburse (or shall cause CG Austria to
pay or reimburse) Seller for any and all costs and expenses reasonably incurred
by Seller in connection with obtaining the FIRB Approval (including Costs
incurred by Seller in meeting any conditions to such approval set forth in any
notification or other document issued by the Treasurer of the Commonwealth of
Australia to any TWC Party in connection with the FIRB Approval (collectively,
"FIRB Approval Costs")); (c) the rights and remedies of any TWC Party against
any WCG Party, CG Austria or WCP in respect of any failure by Seller to obtain
the FIRB Approval as provided herein shall be limited solely to the payment and
reimbursement rights specified in this Section 16; and (d) in connection with
the foregoing, each TWC Party hereby agrees to take, and each WCG Party hereby
agrees to take and/or to cause CG Austria and/or WCP to take, all actions (at
the sole cost and expense of the WCG Parties and/or CG Austria) reasonably
necessary or reasonably requested by Seller in connection with obtaining the
FIRB Approval. Any payment or reimbursement of any FIRB Approval Cost required
to be made by any WCG Party or CG Austria to Seller pursuant to this Section 16
shall be payable by one or more of the WCG Parties or CG Austria promptly upon
and in any event within thirty (30)

                                      -5-
<PAGE>

days after receipt of written demand by Seller therefor. Seller hereby agrees to
(x) promptly notify Purchaser of and provide copies of any notification or other
documentation received by any TWC Party relating to the FIRB Approval and (y)
promptly notify Purchaser in writing of any actual or potential FIRB Approval
Costs of which any TWC Party has notice or knowledge and to specify in
reasonable detail in such written notice the nature of any such FIRB Approval
Costs. The obligations of each WCG Party under this Section 16 shall survive
termination of the Agreement and shall remain in full force and effect until
Seller has obtained the FIRB Approval and delivered a copy thereof to Purchaser
or the occurrence of a Permitted Disposition (as such term is defined in the
Pledge Agreement). The TWC Parties and the WCG Parties hereby further agree that
if Seller, notwithstanding the actions taken by the TWC Parties, the WCG Parties
and/or CG Austria or WCP pursuant to this Section 16 or otherwise in connection
with the FIRB Approval, is unable to obtain the FIRB Approval within 60 days
after November 27, 2002, and Seller determines in its reasonable discretion on
such date that it shall be unable to obtain the FIRB Approval within a
reasonable period of time thereafter, (1) the TWC Parties and the WCG Parties
shall take all necessary actions to rescind the Pledge Agreement and the
Equitable Mortgage and terminate the liens, security interests and encumbrances
granted by CG Austria thereunder (if any); and (2) one or more of the WCG
Parties shall within 60 days thereafter (A) grant (or cause CG Austria (or
another subsidiary or affiliate of any such WCG Party) to grant) a security
interest in and lien on other assets or property (subject in all respects to the
WCG Bank Facility and the Loan Documents (as such term is defined in the WCG
Bank Facility)) pursuant to documentation reasonably acceptable to Seller and CG
Austria in lieu of the Collateral (as such term is defined in the Pledge
Agreement) having a value mutually determined in good faith by the TWC Parties
and the WCG Parties to be reasonably equivalent to the fair value of the
Collateral on such date to Seller to secure the Obligations (as such term is
defined in the Purchase Money Mortgage), subject only to Permitted Encumbrances
(as such term is defined in the Pledge Agreement) (collectively, the "New
Pledge") or (B) cause CG Austria and/or WCP to enter into and consummate a
Permitted Disposition (in each case at the sole cost and expense of the WCG
Parties, provided that any such costs and expenses of any TWC Party are
reasonably incurred by such TWC Party and specified in reasonable detail in
writing to the Purchaser), provided that the TWC Parties shall negotiate in good
faith with and otherwise undertake reasonable efforts to review and/or complete
any such negotiations with the WCP Parties and/or CG Austria in connection with
any such New Pledge or Permitted Disposition.

         17. The parties hereto hereby agree that, pursuant to Section 4.11 of
the Agreement, New WCG shall constitute "New WCG" (as such term is defined in
Section 4.11 of the Agreement (as amended by this Amendment)) without further
action of the parties and that as such Communications (a) shall from and after
October 15, 2002 no longer be a party to the Agreement or have any rights or
obligations under the Agreement (provided that Communications (i) shall remain a
party to the Agreement (as amended by the First Amendment) in all respects and
for all purposes for the period of time prior to and including such date and
shall have all of the rights and obligations specified therein for the period of
time prior to such date) and (ii) notwithstanding the foregoing, Communications
shall be and remain an "Indemnitee" (as such term is defined in Section 41 of
the First Amendment) in all respects for the purposes specified therein for so
long as the indemnification provisions set forth in Section 41 remain in full
force and effect; and (b) shall not be required to execute and deliver this
Amendment. The parties acknowledge and agree that, notwithstanding the
foregoing, each of this Amendment and the

                                      -6-

Agreement (as amended by the First Amendment and this Amendment) shall
constitute valid, binding obligations of each of the parties hereto, enforceable
against each such party in accordance with their respective terms.

         18. This Amendment shall be binding upon each party hereto and shall
inure to the benefit of each party hereto and their respective successors and
permitted assigns.

         19. This Amendment may be executed in one or more counterparts and by
the different parties hereto in separate counterparts, each of which when so
executed shall be deemed to be an original, and all of which when taken together
shall constitute one and the same agreement. The delivery of an executed
counterpart to this Amendment by facsimile shall be as effective as delivery of
a manually executed counterpart of this Amendment.

         20. Each of the parties hereto hereby agree that, except as
specifically amended hereby, the Agreement (as amended by the First Amendment)
and the First Amendment are each confirmed, ratified and approved in all
respects and for all purposes. All references in the Agreement to "this
Agreement" shall mean and refer to the Agreement as amended by the First
Amendment and by this Amendment. All references in the First Amendment to "this
Amendment" shall mean and refer to the First Amendment as amended by this
Amendment.

         21. THIS AMENDMENT SHALL BE CONSTRUED IN ACCORDANCE WITH, AND GOVERNED
BY, THE LAWS OF THE STATE OF OKLAHOMA (WITHOUT GIVING EFFECT TO THE PROVISIONS
THEREOF RELATING TO CONFLICTS OF LAW).

services of Executive as an employee until December 31, 2002, ("Separation
Date") to provide an orderly transition of his responsibilities;

         WHEREAS, the Company has also determined that the continued
availability of Executive to the Company after his retirement is also needed in
order to provide such orderly transition;

         WHEREAS, Executive is willing to delay his retirement to the Separation
Date and to provide consulting services after his retirement in accordance with
the provisions of this Agreement and the Consulting Agreement between the
Company and him, a copy of which is attached hereto as Exhibit "A"; and

         WHEREAS, Executive has requested, effective on his Separation Date, a
distribution of his entire interest in the Williams Companies Supplemental
Retirement Plan ("SERP") and Executive understands that he will not receive any
further consideration, benefits or payments under the SERP;

         NOW, THEREFORE, in consideration of their mutual promises made herein
and for other good and valuable consideration, and intending to be legally
bound, the Company and Executive hereby agree as follows:

<PAGE>

                  1.       Executive Services. Executive agrees to continue to
         provide his services as an employee of the Company until December 31,
         2002, or such earlier time as the Company may determine 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 December 31, 2002, 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.       Company Payments. The Company shall, in consideration
         of Executive's covenants and obligations hereunder:

                           (a)      Pay Executive, on December 31, 2002, the sum
                  of Seven Hundred and Forty-Seven Thousand Dollars ($747,000),
                  less all amounts 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 Executive, provided the
                  Company shall be entitled to apply the net amount due (after
                  applicable tax withholdings) to any outstanding balance,

                                       2

<PAGE>

                  including accrued interest, of Executive under his stock
                  option loans from the Company;

                           (b)      Pay Executive 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 sum of
                  One Hundred Thousand Dollars ($100,000), less all amounts
                  withheld under applicable federal and state tax laws for
                  executing the release set forth on Exhibit "B."

         Unless Executive has repaid his stock option loans, the Company shall
         not be required to deliver any funds to Executive in order to satisfy
         its obligations under subparagraphs 2(a) and 2(b). The Company's
         obligation with respect to such payments shall be limited to: (i)
         withholding and remitting to the appropriate governmental agency the
         applicable withholding amounts under applicable federal and state laws
         and regulations and (ii) with respect to the obligations under
         subparagraph 2(a) and 2(b), applying the remaining amount of such
         payments as an offset to repay Executive's stock option loan until such
         loan is discharged in full with the balance of the payments, if any,
         being remitted to Executive.

                  3.       SERP. 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.

                                       3

<PAGE>

                  4.       Severance. Due to the retention and severance payment
         being made subparagraph 2(a) and 2(b), 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.       Deferred Stock Awards. Executive's existing deferred
         stock awards that are scheduled to vest on January 1, 2003, July 31,
         2003, and August 1, 2004, will continue to vest on such dates, provided
         Executive continues to perform all of his obligations under the
         Consulting Agreement and this Agreement until the applicable vesting
         date. Unless Executive has repaid his stock option loan, upon the
         vesting of a deferred stock award the Company shall not be required to
         deliver any shares to Executive in order to satisfy its obligations
         under this paragraph 5. The Company's obligation with respect to such
         deferred stock shall be limited to: (i) withholding and remitting to
         the appropriate governmental agency the applicable withholding amounts
         under applicable federal and state laws and regulations and (ii)
         applying the remaining shares as collateral for Executive's stock
         option loan until such loan is discharged in full. With respect to
         subparagraph 5(ii), concurrent with the vesting of each deferred stock
         award, Executive agrees to execute and to provide to the

                                       4

<PAGE>

         Company an assignment separate from transfer with respect to the shares
         to be pledged as collateral.

                  6.       Consulting. Executive and Company agree that
         Executive, upon the termination of his employment, will provide
         consulting services to the Company in accordance with the terms of the
         Consulting Agreement attached hereto as Exhibit "A."

                  7.       Execution of Release. Executive agrees to execute no
         earlier than December 31, 2002, the Release Agreement attached hereto
         as Exhibit "B," provided that the Release shall in no way impair
         Executive's rights to indemnity from the Williams Group, including, but
         not limited to, his rights to indemnification under any certificate of
         incorporation, any bylaws, any corporate resolutions, any employee
         benefit plans, any insurance policies or any other instrument or
         agreement to which a member of the Williams Group is bound. 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 shall not be entitled to
         receive a bonus under the Executive Incentive Compensation Program for
         the 2002 calendar year.

                  9.       Indemnification. To the extent permitted by law and
         as provided in its certificate of incorporation and bylaws, the Company
         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.

                                       5

<PAGE>

                  10.      Benefits. Except as otherwise provided in Paragraphs
         2, 3, 4, 5, and 8 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 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. Executive
         also acknowledges that this Paragraph 11 is a material term of this
         Agreement and that its breach could result in damage to the Williams
         Group that may be difficult to ascertain and that upon any such breach
         or in

                                       6

<PAGE>

         reasonable anticipation of any such breach, the Company will be
         entitled to an order of any court of competent jurisdiction to enjoin
         such breach.

                  12.      Exclusive Service. Through the Separation Date,
         Executive shall devote his full business time and attention and his
         best efforts to the performance of his duties hereunder.

                  13.      Derogatory Remarks. Executive will not make public
         derogatory comments regarding the Williams Group or any of its current
         or former directors, officers or employees at any time before or after
         his termination of employment.

                  14.      Files and Records. Promptly upon termination of his
         employment, Executive will return to the Company all property and all
         files and other documentation belonging to or relating or in any way
         pertaining to the Williams Group or the business or operations of the
         Williams Group, except as may be required by Executive in the bona fide
         enforcement of this Agreement.

                  15.      Cooperation in Litigation. To the extent reasonably
         necessary and upon reasonable notice, following his termination of
         employment, Executive will cooperate with the Williams Group in
         connection with the prosecution or defense of any claim asserted by or
         against any of them (excluding a claim in connection with the
         enforcement of this Agreement) with respect to which Executive may have
         any knowledge.

                  16.      General Provisions.

                           (a)      Binding Agreement: This Agreement will be
                  binding upon, and inure to the benefit of, Executive and the

                  permitted assigns.

                              CONSULTING AGREEMENT

         THIS CONSULTING AGREEMENT is entered into this ____ day of December,
2002, by and between THE WILLIAMS COMPANIES, INC. a Delaware Corporation,
("Williams") and Jack D. McCarthy ("Consultant").

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

         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 until August 31, 2004, (the "Consulting
Period"), Consultant shall provide to Williams, its subsidiaries and affiliates
(the "Williams Group"), consulting services commensurate with his status and
experience with respect to the matters enumerated below and such other 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:

                           (i)      Consultant shall assist with the 2002
                           year-end financial closing for the Williams Group;

                           (ii)     Consultant shall assist in the selection of
                           a Chief Financial Officer for the Williams Group and
                           the transition of his replacement;

                           (iii)    Consultant shall assist with the debt
                           restructuring of the Williams Group; and

                           (iv)     Consultant shall assist with the placement
                           of the property and casualty insurance of the
                           Williams Group during the first quarter of 2003.

         Consultant shall provide consulting services to the Williams Group only
         as needed and when reasonably requested by the Williams Representative,

                                       11

<PAGE>

         provided that, without his prior consent, Consultant shall not be
         required to devote more than one hundred twenty (120) hours in any
         calendar month to the performance of any consulting services hereunder,
         and provided further that, until such time as Williams has paid
         Consultant for a minimum of one thousand (1000) hours of consulting
         services and subject to the terms of Paragraph 6 of this Agreement, so
         long as Consultant makes reasonable efforts to be available for
         consulting services during the term of this agreement, Williams shall
         pay Consultant for a minimum of fifty (50) hours of consulting services
         during each month of the Consulting Period. Upon such time as Williams
         has paid Consultant for a minimum of one thousand (1000) hours, there
         shall be no monthly minimums for consulting 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.

                  (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. 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
         the Williams Group.

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

                   (b)     In respect of the services to be performed hereunder,
         Williams shall pay Consultant Three Hundred Fifty Dollars ($350.00) for
         each hour of consulting service, within ten (10) business days
         following submission by Consultant of an itemized report indicating the
         hours of service performed during the reporting period and fully
         describing the services rendered. The first such itemized report shall
         indicate the hours of service performed up to the date of that first
         report. Each succeeding report shall indicate the hours of service
         performed since the most recent report. Until such time as Williams has
         paid Consultant for a minimum of one thousand (1000) hours of
         consulting services, each itemized report shall include the minimum
         billing for fifty (50) hours of consulting services each month
         described in Paragraph 1(a) above plus any additional hours of service
         rendered during the reporting period. Williams shall also reimburse
         Consultant for such reasonable travel, lodging and other appropriate
         expenses incurred by Consultant in the course or on account of
         rendering consulting services hereunder, subject to the submission by
         Consultant of evidence of such expenses in a form reasonably
         satisfactory to Williams. Consultant shall be eligible for a
         discretionary bonus in an amount determined by the Company at the end
         of the Consulting Period, provided the Company determines, in its sole
         discretion that he properly performed all of his obligations under this
         Agreement during the Consulting Period.

         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 the Williams
Group or (ii) other technical,

                                       13

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 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.       Noncompetition; Nonsolicitation.

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

                  (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

                                       14

<PAGE>

         in engaging or being engaged, in any business, in which Consultant was
         involved or of which he has knowledge is being conducted by the
         Williams Group during the Consulting Period, in any geographic area in
         which the Williams Group is then conducting such business.
         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 of Williams Group 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 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

                                       15

<PAGE>

         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 gross negligence or willful misconduct in performing under this
Agreement.

         6.       Termination of the Consulting Services. Williams may terminate
this Agreement solely for cause, which shall be limited to either (i) the
conviction of Consultant of a felony which has a substantial effect on the
business or reputation of the Williams Group 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.

         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 December 18, 2002.

                                       16

         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). 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 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.

                                       17

<PAGE>

Williams and Consultant acknowledge that this Agreement evidences a transaction
involving interstate commerce.

         10.      Computer Support and Access. During the Consulting Period,
Williams shall provide and maintain Consultant's computer and access to
Williams' network and telephone systems via his home office as shall be
reasonably necessary for Consultant to provide the consulting services requested
by the Williams Group under the terms of this Agreement.

         1)       Miscellaneous. This Agreement may only be amended by a written
instrument signed by Williams and Consultant. Except as otherwise expressly
provided hereunder, this Agreement shall constitute the entire agreement between
Williams and Consultant with respect to the subject matter hereof. This
Agreement may be executed in counterparts, each of which shall be deemed an
original but all of which together shall constitute one and the same instrument.

         12.      Notices. Any and all notices required to be sent pursuant to
the terms of this Agreement will be sent by registered or certified mail or be
