                                    AGREEMENT

          This Agreement (together with the Exhibits hereto, the "Agreement"),

Inc. ("WCG"), Williams Communications, LLC ("WCLLC"), CG Austria, Inc. ("CGA"),
and each of WCG's other undersigned direct or indirect subsidiaries
(collectively, with WCG , WCLLC and CGA, the "Company"); (b) each of the
undersigned holders in their capacities as described in the attached signature

due 2007, 10.875% Senior Redeemable Notes due 2009, 11.70% Senior Redeemable
Notes due 2008, and 11.875% Senior Redeemable Notes due 2010, in each case
issued by WCG (collectively, the "Notes"), and (c) each of the undersigned
lenders (collectively, the "Consenting Lenders") party to that certain Amended
and Restated Credit Agreement dated as of September 8, 1999, as amended,
restated, supplemented or modified from time to time (the "Credit Agreement")
among WCLLC, as Borrower, WCG and CGA, each as a Guarantor, the lenders party
thereto (collectively, "Lenders"), and Bank of America, N.A., as Administrative
Agent (the "Agent") for the Lenders and certain other parties. The Company, each
Noteholder, each Consenting Lender, and the Agent are referred to herein
collectively as the "Parties".

          WHEREAS The Williams Companies, Inc. ("TWC") and WCG are parties to a
letter agreement dated as of February 23, 2002, pursuant to which, among other
things, TWC agreed to support the implementation of the restructuring of the
Company's obligations to its creditors (the "Restructuring") through the
prosecution and confirmation of a plan of reorganization in accordance with the
provisions of chapter 11 of title 11 of the United States Code (the "Bankruptcy
Code");

          WHEREAS the Parties have engaged in good faith negotiations with the
objective of reaching agreement concerning the Restructuring; and

          WHEREAS the Parties now desire to enter into this Agreement to further
implement the Restructuring through (1) certain modifications to the Credit
Agreement; (2) the commencement of cases with respect to WCG and CGA
(collectively, the "Chapter 11 Case") under chapter 11 of title 11 of the
Bankruptcy Code in the United States Bankruptcy Court for the Southern District
of New York or such other bankruptcy court with proper jurisdiction (the
"Bankruptcy Court"); and (3) the prosecution of a plan of reorganization
containing terms substantially similar in all material respects with the
provisions set forth in this Agreement and the Exhibits hereto (the "Plan").

          NOW, THEREFORE, in consideration of the premises and mutual covenants
and agreements set forth herein, and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, each of the
undersigned Parties hereby agrees as follows:

1.        INTERIM AMENDMENT AND CASH COLLATERAL ORDER. Prior to the entry of an
     order for relief under chapter 11 of title 11 of the Bankruptcy Code in the
     Chapter 11 Case, each of the Consenting Lenders, WCG and WCLLC will execute
     and deliver an interim amendment to the Credit Agreement substantially in
     the form annexed hereto as Exhibit "A" (the "Interim Amendment"). The
     Parties further agree that they (a) will not challenge, or support a
     challenge to, the validity or enforceability of the Interim

<PAGE>

     Amendment and (b) will support the entry or of an order authorizing WCG's
     and CGA's use of cash collateral on the terms described in, and
     substantially in the form of, Exhibit "B" hereto (the "Cash Collateral
     Order").

2.        AMENDED CREDIT AGREEMENT. Subject to satisfaction of the conditions
     set forth herein and in the Exhibits hereto, the Company and each of the
     Consenting Lenders agrees to execute an amended and restated Credit
     Agreement that is consistent in all material respects with the terms set
     forth in Exhibit "C" hereto (the "Amended Credit Agreement") and to deliver
     such agreement on the effective date of the Plan (the "Consummation Date").
     The Parties agree that (a) the Plan will authorize WCG's and CGA's entry
     into the Amended Credit Agreement; and (b) the Plan will be consistent with
     the terms and conditions of the Amended Credit Agreement.

3.        CONSENTING LENDER AMENDMENT FEE. On the Effective Date (as such term
     is hereinafter defined), WCLLC will pay indefeasibly in cash to the Agent
     for the pro rata benefit of the Consenting Lenders, a fully-earned,
     non-refundable fee in the aggregate amount of $7.904 million (the
     "Consenting Lender Amendment Fee"). Further, the Parties waive and release
     any right to challenge or object to in any respect the Consenting Lender
     Amendment Fee.

4.        PREPAYMENT OF AMORTIZATION. (a) On the Effective Date, WCLLC will
     prepay, indefeasibly in cash, $200 million of the outstanding principal
     balance under the Credit Agreement (the "Initial Payment"); and (b) on the
     Consummation Date, WCLLC will prepay, indefeasibly in cash, $250 million of
     the outstanding principal balance under the Credit Agreement (the
     "Subsequent Payment"), provided, however, that if the Extension Payment (as
     such term is herein defined) is paid on July 15, 2002, the Subsequent
     Payment shall be reduced to $200 million. All of the payments under the
     Credit Agreement set forth in this paragraph shall be applied to the next
     scheduled amortization payments under the Credit Agreement, in
     chronological order. The Parties waive and release any right to challenge
     or object to, in any respect, the making by WCLLC of the Initial Payment,
     the Subsequent Payment or the Extension Payment and under no circumstance
     shall the Consenting Lender Amendment Fee, the Initial Payment, the
     Subsequent Payment, the Extension Payment or any other fee or amount paid
     by WCLLC under or in connection with this Agreement or the Initial
     Amendment be subject to repayment, reallocation or return by the Agent, the
     Consenting Lenders or the Lenders, as the case may be.

5.        TREATMENT OF CLAIMS UNDER THE PLAN. The Parties agree to the following
     treatment of certain claims (as such term is defined under section 101 of
     the Bankruptcy Code, "Claims") under the Plan:

     (a)  GENERAL UNSECURED CLAIMS. In full satisfaction of all Claims that are
          unsecured prepetition non-priority Claims and that have become allowed
          Claims in the Chapter 11 Case ("Unsecured Claims"), each holder
          thereof shall receive a pro rata share of 100% of the new common stock
          (the "New Common Stock") of WCG, as reorganized under the Plan
          ("Reorganized WCG").

     (b)  CLAIMS ARISING UNDER THE WCG AND CGA GUARANTIES. The guaranties of WCG
          and CGA of WCLLC's obligations under the Credit Agreement will be
          unimpaired by the Plan (except as otherwise agreed to by that portion
          of the

<PAGE>

          Consenting Lenders which constitute Required Lenders (as herein
          defined) in their sole discretion) on the Consummation Date. In
          addition, the Administrative Agent, for itself and on behalf of the
          Lenders, shall retain its liens upon the collateral securing such
          guaranties unaffected by the Plan or any order entered in the Chapter
          11 Case.

     (c)  SECURITIES CLAIMS. To the fullest extent permitted under section
          510(b) of the Bankruptcy Code, holders of Claims arising from
          rescission of a purchase or sale of the WCG preferred stock, or the
          WCG common stock (collectively, the "WCG Securities"), for damages
          arising from the purchase or sale of WCG Securities, or for
          reimbursement or contribution on account of such Claims, shall receive
          no distribution under the Plan and such claims shall be discharged.

6.        GOVERNANCE OF REORGANIZED WCG. The Plan will provide for a nine-person
     board of directors for Reorganized WCG, to be initially comprised of the
     CEO, at least two current directors selected by the current board of
     directors of WCG and six directors who will be selected by the members of
     the official committee of unsecured creditors appointed in the Chapter 11
     Case (the "Creditors' Committee").

7.        PURSUE PLAN PROCESS. WCG and CGA agree that, pursuant to section 1125
     of the Bankruptcy Code, they shall file and use their reasonable best
     efforts to obtain approval by the Bankruptcy Court of a disclosure
     statement and other solicitation materials in respect of the Plan
     (collectively, the "Disclosure Statement"), which shall be reasonably
     acceptable to the Required Lenders, the Required Noteholders and the
     Company, and, pursuant to section 1129 of the Bankruptcy Code, use their
     commercially reasonable efforts to obtain confirmation and consummation of
     the Plan as soon as practicable. WCG and CGA agree that, promptly after the
     commencement of the Chapter 11 Case, they will file a motion for an order
     authorizing the assumption of this Agreement pursuant to section 365 of the
     Bankruptcy Code and shall diligently prosecute such motion in good faith.

8.        VOTE FOR PLAN. Subject to the terms and conditions of this Agreement,
     each of the undersigned Noteholders and Consenting Lenders (each a "Holder"
     and, collectively, the "Holders") agrees that, so long as it remains
     obligated under this Agreement, and subject to the receipt of a Disclosure
     Statement that contains information not materially different from that
     previously provided to the initial signatories hereto and that is approved
     by the Bankruptcy Court as containing "adequate information" under section
     1125 of the Bankruptcy Code:

     (a)  to the extent a Holder's Claim is impaired, in connection with any
          solicitation of ballots by WCG and CGA with respect to the Plan, it
          will vote all of its Holdings (as such term is defined hereinafter) to
          accept the Plan by delivering its duly executed and completed ballot
          accepting the Plan, and will not change or withdraw (or cause to be
          changed or withdrawn) such votes(s);

     (b)  it will not (i) object to the Plan or (ii) propose, file, support or
          vote for any restructuring, workout, or plan of reorganization for WCG
          and CGA other than the Plan;

<PAGE>

     (c)  it will vote against any restructuring, workout or plan of
          reorganization relating to WCG and CGA other than the Plan;

     (d)  each Noteholder agrees that it will not (nor will it encourage any
          other person to) delay, impede, or take any other action to interfere,
          directly or indirectly, in any respect with acceptance or
          implementation of the Plan and that it will not object to the separate
          classification of allowed Claims arising under the Notes (other than
          those subordinated pursuant to section 510(b) of the Bankruptcy Code)
          from all other allowed Claims; and

     (e)  each Consenting Lender agrees that, effective upon consummation of the
          Plan, the Agent shall, and is hereby authorized to, waive any and all
          super priority Claims under the Cash Collateral Order;

provided, however, that no Holder shall be barred by this Agreement from
objecting to approval of the Disclosure Statement pursuant to section 1125 of
the Bankruptcy Code if such Holder believes in good faith that the proposed
Disclosure Statement lacks "adequate information" (as such term is defined in
section 1125(a)(1) of the Bankruptcy Code) or contains a material misstatement
or omission.

9.        CLAIM HOLDINGS AND TRANSFERS; PARTICIPATION RIGHT

     (a)  Each of the undersigned Noteholders represents that with respect to
          the Claim or Claims against WCG in the principal amount set forth on
          such Noteholder's signature page (the "Note Holdings"), it is the
          beneficial owner and/or the investment advisor or manager on behalf of
          the beneficial owner of such Holdings with the power to vote and
          dispose of such Holdings in accordance with this Agreement on behalf
          of such beneficial owners.

     (b)  Each of the undersigned Consenting Lenders represents that it is (i)
          the owner and/or the investment advisor or manager on behalf of the
          owner of a Claim arising under the Credit Agreement (a "Credit
          Agreement Claim" and, together with Note Holdings, "Holdings") in the
          principal amount set forth opposite its name in Exhibit "D" attached
          hereto.

     (c)  From the Effective Date until the Consummation Date, each Holder
          agrees that it will not sell, pledge, assign, hypothecate, or
          otherwise transfer any Holdings, and such attempted sale, pledge,
          assignment, hypothecation, or other transfer shall be void and without
          effect, unless the transferee executes and delivers to each of the
          Noteholders, counsel to WCG and counsel to the Agent (such counsel
          being the counsel designated in Section 23) a counterpart signature
          page to this Agreement, thereby agreeing to be bound by all of the
          terms of this Agreement with respect to the Holdings being
          transferred.

     (d)  This Agreement shall in no way be construed to preclude a Noteholder
          from acquiring additional Notes or other Claims against WCG or CGA and
          the provisions of this Agreement, including without limitation, the
          restrictions on transfer set forth in Section 9(c), shall not be
          applicable to any such additional Notes. However, to the extent the
          undersigned Noteholder is the beneficial owner of, or has control over
          an affiliate that is the beneficial owner of Notes other than Note
          Holdings on the record date established for voting on acceptance or
          rejection of the Plan, it shall vote such additional Notes to accept
          the Plan, subject to the

<PAGE>

          satisfaction of the terms and conditions set forth in Section 8(a)
          (including the lead-in paragraph thereto).

     (e)  The Plan will provide that WCG and/or WCLLC, in connection with
          procuring the New Investment (as herein defined), will offer each
          Noteholder that has Note Holdings of at least $125 million and that
          has delivered to WCG a signature page to this Agreement on or before
          April 22, 2002 and TWC (collectively, the "Lock-Up Parties") the right
          to invest (the "Additional Investment") up to an additional $150
          million (above the amount of the New Investment) on the same terms and
          conditions as the New Investment, subject to dilution by the
          Additional Investment. If the Additional Investment is oversubscribed,
          participation shall be pro rated among the Lock-Up Parties based on
          the amount of New Common Stock to be issued to them upon consummation
          of the Plan. The rights contained in this paragraph are not
          transferable.

     (f)  The Plan will provide that WCG, for a period of two years commencing
          on the Consummation Date, will provide ROFO Eligible Parties (as
          hereinafter defined) a Right of First Offer (as hereinafter defined)
          with respect to any public or qualifying private issuance (as
          hereinafter defined) of debt or equity securities (including
          equity-linked securities) by WCG involving amounts (in any individual
          transaction or series of related transactions) aggregating in excess
          of $50 million (a "Covered Issuance"). For this purpose, a "qualifying
          private issuance" shall mean a straight issuance of debt or equity
          securities not involving a strategic partnering with a key customer or
          supplier. As used herein, a "ROFO Eligible Party" shall mean any
          Noteholder that has delivered to WCG a signature page to this
          Agreement on or before April 22, 2002 or TWC, as to which all of the
          following conditions have been satisfied: (i) the Noteholder or TWC,
          as the case may be, shall have elected to be treated as a ROFO
          Eligible Party in connection with voting on the Plan and shall have
          made a one-time qualifying payment to WCG in the amount of $100,000
          and (ii) at the time any Right of First Offer is made it holds (A) in
          the case of a Noteholder, New Common Stock in an amount equal to the
          greater of (x) 50% of the New Common Stock issued in respect of the
          Holdings set forth opposite the Noteholder's signature to this
          Agreement, and (y) 50% of the New Common Stock issued in respect of
          the Notes voted by the Noteholder to accept the Plan, and (B) in the
          case of TWC, New Common Stock in an amount equal to 50% of the New
          Common Stock, if any, issued to TWC under the Plan. As used herein, a
          "Right of First Offer" shall require WCG to offer (the "Offer") to
          ROFO Eligible Parties the first right to subscribe to a Covered
          Issuance on such terms and conditions as shall be set forth by WCG in
          a written notice accompanying the Offer. In the case of a Covered
          Issuance that is a qualifying private issuance (a "Private Issuance
          Offer") as to which the ROFO Eligible Parties have only partially
          subscribed (with the amount subscribed being herein the "Partial
          Subscription Amount"), WCG shall be free to pursue the Private
          Issuance Offer with third parties; provided, however, that WCG shall
          seek to permit the ROFO Eligible Parties to participate to the extent
          of the Partial Subscription Amount, and, if necessary to accommodate
          such participation, will increase the size of the Private Issuance
          Offer (it being understood that WCG shall not be obligated to make
          such participation available if it would cause the Private Issuance
          Offer to be unacceptable to third parties); provided, further, that

<PAGE>

          if the terms of the Private Issuance Offer that relate to equity of
          WCG, if any, as negotiated with the third party investors are
          materially improved (from the standpoint of the investors), WCG will
          offer the ROFO Eligible Parties the right to invest collectively up to
          25% of the amount invested by the third party investors on the same
          terms and conditions as the third parties. In the case of a Covered
          Issuance that is a public offering as to which the ROFO Eligible
          Parties have only partially subscribed, WCG will be free to offer and
          sell to third parties that portion of the offering which was not
          subscribed to by the ROFO Eligible Parties and there will be no
          further obligation on WCG's part to make an Offer to the ROFO Eligible
          Parties in respect of such Covered Issuance. To the extent any Offer
          is oversubscribed by the ROFO Eligible Parties, participation in the
          Offer shall be pro rated among the ROFO Eligible Parties based on
          their respective holdings of New Common Stock at the time of the
          Offer. The rights of a ROFO Eligible Party shall not be transferrable.

     (g)  In consideration for agreeing to be bound herein, and not to sell or
          transfer their holdings of Notes (except as provided herein), the
          Noteholders will receive a pro rata share of 5% of the equity to be
          provided to the class of holders of Notes, provided however that the
          Plan ballots shall provide a separate check off whereby members of the
          Noteholders Class can vote to disapprove such additional equity
          issuance, and provided further that the Bankruptcy Court must find
          that such additional equity issuance does not constitute unfair
          discrimination with respect to the remaining members of the class of
          Noteholders or otherwise cause the Plan to fail to comply with any
          other requirement of section 1129 of the Bankruptcy Code.

10.       CONDITIONS TO EFFECTIVENESS OF THIS AGREEMENT. This Agreement shall
     not become effective until such time as each of the following conditions
     have been satisfied (the "Effective Date"):

     (a)  The receipt by WCG of the signatures to this Agreement by sufficient
          numbers of the Consenting Lenders which comprise "Required Lenders"

          the Interim Amendment;

          payment by WCLLC pursuant to this Section 11(a) shall be applied to
          the next scheduled amortization of payments, in chronological order
          and shall reduce dollar-for-dollar the amount required to be paid by
          WCLLC as a Subsequent Payment pursuant to Section 4(b)); provided,
          further, however, that such extension shall automatically terminate if
          another Termination Event pursuant to this Section 11 shall occur at
          any time during such extension from July 15,2002 to October 15, 2002;
          or

          the terms and conditions of this Agreement, or the Plan is amended,
          modified, or supplemented in any way that makes it materially

          terms and conditions of this Agreement; or

     (c)  WCG and CGA shall have failed to file a motion in the Chapter 11 Case

          all material respects acceptable to that portion of the Consenting
          Lenders which constitute Required Lenders and in all material respects
          reasonably acceptable to the Creditors' Committee (such investment,
          the "New Investment"); or

          Statement on or before May 20, 2002; or

     (f)  The Cash Collateral Order is not entered by the Bankruptcy Court by

          Lenders; or

     (g)  Any Event of Default (as such term is defined in the Credit Agreement)
          under the Credit Agreement occurs and is continuing without waiver by
          the Lenders required pursuant to Section 10.02 of the Credit
          Agreement; or

     (h)  (i) The Company shall seek an order or judgment of the Bankruptcy
          Court or any other court of competent jurisdiction to affect adversely
          or alter in any respect the rights or remedies of, or to stay the
          exercise of the rights or remedies of, the Agent or the Lenders with
          respect to WCLLC or its property (including by asserting that any stay
          or injunction in the Chapter 11 Case, under section 362 of the
          Bankruptcy Code or otherwise, that affects the Agent's or the Lenders'
          respective rights or remedies with respect to WCLLC or its property)
          or (ii) the Bankruptcy Court or any court of competent jurisdiction
          enters any such order or judgment sought by the Company or any other
          entity, in which case, this Agreement shall automatically terminate
          immediately prior to the entry of such an order or judgment; or

     (i)  If WCG and CGA shall have failed to propose in the Plan the separate
          classification of allowed Claims arising under the Notes (other than
          those subordinated pursuant to section 510(b) of the Bankruptcy Code)
          from all other allowed Claims.

Notwithstanding anything in this Section 11 to the contrary, this Agreement
shall automatically terminate on October 15, 2002 without the requirement of any
further action by any of the Parties hereto.

If the Bankruptcy Court enters an order authorizing WCG and CGA to assume this
Agreement, then the introductory clause of this Section 11 and the second
proviso in Section 11(a) shall be deemed to be modified to (a) require a Party
(in the case of the Consenting Lenders, by the Agent at the direction of those
Consenting Lenders that constitute the Required Lenders and, in the case of the
Noteholders, by the informal committee of Noteholders (the "Informal Noteholders
Committee") at the direction of the Required Noteholders) to give written notice
of termination of this Agreement to the other Parties in order for a termination
pursuant to this Section 11 to become effective (which termination will become
effective upon delivery of such written notice) and (b) to delete in its
entirety the following language: "(except with respect to Sections 11(b) and
11(i), as to which if the event specified therein occurs, this Agreement shall
terminate at 5:00 p.m. Eastern Time on the second business day after such event
has occurred)" from the introductory clause of this Section 11. For purposes of
this Agreement, "Required Noteholders" means holders of not less than 51% in
principal amount of the Note Holdings of the Noteholders.

12.       EFFECT OF A TERMINATION OF THIS AGREEMENT. Upon termination of this
     Agreement pursuant to Section 11, this Agreement will be void and of no
     further force and effect except that Sections 1, 3, 4(a), the last sentence
     of Section 4 (except with respect to the Extension Payment, unless made, or
     the Subsequent Payment) and 17 through 29 will survive any termination of
     this Agreement and remain in full force and effect.

13.       GOOD FAITH NEGOTIATION OF DOCUMENTS. Each of the Parties hereby
     covenants and agrees to negotiate in good faith the definitive documents
     relating to this Agreement, including the Plan and Disclosure Statement.

14.       REPRESENTATIONS AND WARRANTIES. Each of the Parties hereby represents

          and shall not (i) violate any provision of law, rule, or regulation
          applicable to it or any of its affiliates, or its certificate of
          incorporation or bylaws or other organizational documents or those of
          any of its affiliates, or (ii) conflict with, result in a breach of,
          or constitute (with due notice or a lapse of time or both) a default
          under any material contractual obligation to which it or any of its
          affiliates is a party or under its certificate of incorporation or
          bylaws or other organizational documents;

     (d)  The execution, delivery, and performance by it of this Agreement does
          not and shall not require any registration or filing with, the consent
          or approval of, notice to, or any other action with respect to
          federal, state, or other governmental authority, regulatory body,
          except such filings as may be necessary or required for disclosure by
          the Securities Exchange Commission.

     (e)  This Agreement is the legally valid and binding obligation of it,
          enforceable against it (in the case of Agent, only in its capacity as
          a Lender) in accordance with the Agreement's terms, except as
          enforcement may be limited by bankruptcy, insolvency, reorganization,
          moratorium, or other similar laws relating to or limiting creditors'
          rights generally, or by equitable principles relating to
          enforceability.

15.       SPECIFIC PERFORMANCE. It is understood and agreed by each of the
     Parties that money damages would not be a sufficient remedy for any breach
     of this Agreement by any Party, and each non-breaching Party shall be
     entitled to specific performance and injunctive or other equitable relief
     as a remedy for such breach.

16.       APPOINTMENT TO A CREDITORS' COMMITTEE. Notwithstanding anything herein
     to the contrary, if any Noteholder is appointed to and serves on a
     Creditors' Committee, the terms of this Agreement shall not be construed to
     limit such Noteholder's exercise of its fiduciary duties to any person
     arising from its service on a Creditors' Committee, and any exercise of
     such fiduciary duties shall not be deemed to constitute a breach of the
     terms of this Agreement, provided, however, that a Noteholder's service on
     a Creditors' Committee shall not affect the continuing validity and
     enforceability of this Agreement, or modify or limit such Noteholder's
     obligations under this Agreement, including its obligation to vote to
     accept the Plan and related obligations contained in Section 8 of this
     Agreement. To the extent that a formal Creditors' Committee is constituted,
     the Parties agree to cooperate in the appointment of the members of the
     Informal Noteholders Committee as the members of the Creditors' Committee.

                      [WILLIAMS COMMUNICATIONS LETTERHEAD]

     Dated as of February 23, 2002

     To The Williams Companies, Inc.:

     Williams Communications Group, Inc. ("WCG") and its subsidiaries
(collectively, the "Company"), including but not limited to Williams
Communications, LLC ("WCL"), is pursuing a restructuring of its obligations to
its creditors. The Company anticipates the primary creditor constituencies that
will participate in any restructuring undertaken by the Company include (i) The
Williams Companies, Inc. ("WCI" and together with its subsidiaries and
affiliates, "Williams"),(1) (ii) WCL's secured bank creditors and (iii) the
holders of WCG's 10.70%, 10.875%, 11.70% and 11.875% Senior Redeemable Notes
(the "Bondholder Claims").

     In order to ensure that its restructuring is binding on all members of
these constituencies, the Company anticipates that it may be implemented through
the prosecution and confirmation of a plan(s) of reorganization in accordance
with the provisions of chapter 11 of title 11 of the United States Code (11
U.S.C. Sections 101 et seq., the "Bankruptcy Code"). Williams, however, has
determined that, as a consequence of the Company's financial difficulties and
potential restructuring, (i) the Company's ability to discharge certain
obligations that affect Williams under the Structured Note Transaction is
uncertain and (ii) the Structured Note Transaction should be restructured
through a consent solicitation.

     Accordingly, the Company and Williams agree (the "Business Agreements")
that (i) the Company must take steps to preserve and maintain its enterprise
value for the benefit of its creditors and other constituents (and to that end,
further agree that the reorganized Company

----------

     (1) The following are the claims held by Williams against the Company (the
"Williams Claims"):

     (i) claims arising from various agreements pursuant to which Williams
provides the Company with administrative and related services of the kind set
forth in the Administrative Services Agreement, dated April 23, 2001 (the
"Williams Services Claims");

     (ii) claims arising from sale leaseback transactions set forth in the
Master Lease Agreement, dated September 13, 2001, and the three Aircraft Dry
Leases, dated as of September 13, 2001 (the "Sale Leaseback Claims");

     (iii) all other claims of Williams, including without limitation, claims
arising from the provision by Williams of financial accommodations and other
claims relating to the ADP Lease and the Trust Notes (the "Structured Note
Transaction"), together with interest costs and fees related thereto ( the
"Williams Other Claims").

<PAGE>

should emerge from any chapter 11 case in the most expedient and efficient
manner possible, including the prompt prosecution and confirmation of a chapter
11 plan) and (ii) the restructuring of the Structured Note Transaction, as
proposed by Williams, is necessary and advisable (and that WCG should deliver
its consent to same).

     As is always possible in any case under the Bankruptcy Code, Williams and
the Company acknowledge that there may be disputes among the Company's creditors
respecting their relative rights against the Company. Thus, each of Williams and
the Company, and their respective legal and financial advisors have separately
reviewed the Business Agreements and considered, without admission or
conclusion, a broad range of potential disputes, objections and litigation that
could be asserted in a chapter 11 case regarding the Company. To that end,
Williams and the Company have thus agreed on the terms set forth below in order
to achieve the Business Agreements' objective of the prompt prosecution and
confirmation of a chapter 11 plan.

     Accordingly, in exchange for good and valuable consideration, the receipt
and sufficiency of which is hereby acknowledged, WCG and WCI, for and on behalf
of their respective subsidiaries and affiliates, intending to be legally bound,
hereby enter into this letter agreement (the "Agreement") and agree as follows:

     1. The Company's Restructuring. In connection with any bankruptcy case
regarding the Company, the Company anticipates that it would prosecute a chapter
11 plan (including any amendment and/or modification thereof, the "Plan") which
would restructure the secured bank claims against WCL, enable the Company to
continue to pay and perform on the Williams Services and Sale Leaseback Claims
and convert to equity the Bondholder Claims and the Williams Other Claims. In
connection with any such Plan,:

     a)   the Company undertakes that it shall propose the following (the
          "Williams Plan Treatment"):

          i)   WCL shall assume or otherwise make unimpaired the Service
               Agreements, as required by the Bankruptcy Code, or as otherwise
               agreed to by Williams or directed by an order of the Bankruptcy
               Court having jurisdiction over the Company's chapter 11 case;

          ii)  WCL shall assume or otherwise make unimpaired the Sale Leaseback
               Claims, as required by the Bankruptcy Code, or as otherwise
               agreed to by Williams or directed by an order of the Bankruptcy
               Court having jurisdiction over the Company's chapter 11 case; and

          iii) WCG recognizes the Williams Other Claims are general unsecured
               claims against WCG that are not subordinate to any other general
               unsecured claim or interest, and provides for the Williams Other
               Claims a treatment that is substantially identical to the
               treatment of the Bondholder Claims (although WCG reserves the
               right to classify the Williams Other Claims separately).

<PAGE>

     b)   So long as the Plan contains the Williams Plan Treatment, Williams

          i)   agrees not to cast any vote to reject the Plan, object to the
               Plan or otherwise delay confirmation of the Plan; provided that
               such agreement not to delay shall not require Williams to
               compromise or surrender any of its rights or remedies except as
               otherwise expressly provided herein;

          ii)  agrees that it will vote all of its Claims to accept the Plan,
               unless Williams first delivers to the Company a written notice
               describing provisions contained in the Plan that, pursuant to a
               good faith determination by Williams, would have a materially
               adverse affect on it (it being understood that the provision of
               warrants or similar rights to holders of existing equity
               interests or litigation, objections, disputes, delays or other
               impairments with respect to distributions of the Williams Plan
               Treatment shall not have a materially adverse affect on
               Williams).

          iii) reserves, to the extent consistent with the Business Agreements,
               all of its rights to prosecute claims and respond to any
               litigation, objection, dispute or other delay or impairment to
               the distribution of the Williams Plan Treatment.

     c)   Williams and the Company agree that no vote on the Plan shall become
          effective until all conditions to such have been satisfied or waived
          as provided under the Bankruptcy Code.

     2. Amendments and Modifications. Each of the parties hereto shall negotiate
in good faith all amendments and modifications to the Plan as reasonably
necessary and appropriate to obtain Bankruptcy Court confirmation of the Plan
pursuant to a final order of the Bankruptcy Court, provided that any such
amended or modified Plan shall provide to Williams substantially the same rights
and benefits as those provided in section (1) hereunder.

     5. William's Restructuring of the Structured Note Transaction.

     a)   the Company understands and acknowledges that Williams intends to
          solicit consents (the "Consent Solicitation") of certain holders of
          the 8.25% Senior Secured Notes due 2004 (the "Trust Notes") of WCG
          Note Trust (the "Issuer") and WCG Note Corp., Inc. (the "Co-Issuer")
          upon the terms and subject to the conditions set forth in a consent
          solicitation statement substantially in the form of Exhibit A hereto
          (the "Consent Solicitation Statement"). Accordingly, this agreement
          shall terminate and be of no further force or effect to the extent a
          petition for relief under the Bankruptcy Code is filed by or against
          the Company prior to the earlier of:

          i)   March 15, 2002; and

          ii)  the successful consummation of the Consent Solicitation

     b)   Williams understands and acknowledges that the Company will enter, and
          will cause WCL, the Issuer and the Co-Issuer to enter, into the
          Ancillary Documents in reliance upon the execution and delivery of
          this Agreement by WCI. Accordingly, prior to the commencement of the
          Consent Solicitation, the Company agrees to:

          i)   execute and deliver the WCG Supplemental Indenture (as defined in
               the Consent Solicitation Statement);

          ii)  cause WCL to execute and deliver an irrevocable letter to
               Wilmington Trust Company, as trustee of the Issuer (the "Issuer
               Trustee"), directing

<PAGE>

               the Issuer Trustee to execute and deliver, on behalf of the
               Issuer, (i) the Supplemental Indenture (as defined in the Consent
               Solicitation Statement) and (ii) the Williams Payment Agreement
               (as defined in the Consent Solicitation Statement); and

          iii) cause the Co-Issuer to execute and deliver the Supplemental
               Indenture (each of the foregoing being collectively referred to
               as the "Ancillary Documents"); and

          iv)  execute and deliver, and cause WCL, the Issuer and the Co-Issuer
               to execute and deliver, such other documents and instruments and
               take such further actions as may be necessary in order to effect
               the transactions contemplated by the Consent Solicitation
               Statement.

     6. Other Agreements.

     a)   Williams shall make all required interest payments for the period from
          the date of this letter through and including September 30, 2002,
          under the 8.25% Senior Reset Notes due 2008 held by WCG Note Trust as
          security for the Trust Notes. Upon payment by Williams of such
          interest payments, the Company shall be relieved of all obligations
          for such interest payments. In connection with the foregoing interest
          payments, Williams shall waive all rights of repayment, reimbursement,
          contribution and subrogation that may exist with respect to the
          Company (including, but not limited to, any such rights that may exist
          pursuant to the Amended and Restated Indemnification Agreement dated
          April 23, 2001 between WCI and WCG).

     b)   Williams shall defer until September 15, 2002 any payments that may be
          due by the Company under the April 23, 2001 letter regarding Deferral
          of Certain Payment Obligations between WCI and WCG.

     7. No Transfer. Williams shall not, directly or indirectly, sell, transfer,
pledge, hypothecate, encumber, assign or dispose of ("Transfer"), or enter into
an agreement, whether or not in writing, to Transfer, any Williams Claims unless
the transferee shall agree to be bound by the terms of this Agreement with
respect to such transferred Williams Claim.

     8. Further Assurances. Each party shall, at the request of the other party,
execute and deliver such other documents and instruments and take such further
actions, at the cost and expense of the requesting party, as may be necessary in
order to ensure that the requesting party receives the full benefit of this
Agreement.

     9. No Third-Party Beneficiaries. This Agreement is solely for the benefit

agreements with the Company substantially identical to this Agreement and no
other person or entity shall be a third-party beneficiary hereof.

     10. Fiduciary Duties. Notwithstanding anything to the contrary contained
herein, nothing in this Agreement requires the Company to breach any respective
fiduciary obligation that it may have under applicable law, and the Company may
commit any act or take any actions

<PAGE>

consistent with such fiduciary obligations, but no such action shall expand any
obligations that Williams has under this Agreement.

     11. Entire Agreement. This Agreement constitutes the entire agreement
between the parties hereto with respect to the subject matter hereof and
supersedes all other prior agreements and understandings, both written and oral,

limitation, that certain prior version of this Agreement executed on February
23, 2002 which is amended and replaced hereby.

     12. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York (without giving effect to the
provisions thereof relating to conflicts of law).

     13. Remedies. The parties hereto acknowledge and agree that any breach of
the terms of this Agreement would give rise to irreparable harm for which money
damages would not be an adequate remedy and accordingly the parties hereto agree
that each party will be entitled to the sole and exclusive remedy of specific
performance and injunctive or other equitable relief without the necessity of
proving the inadequacy of money damages as a remedy or posting a bond or other
security in connection with such remedy.

     14. Jurisdiction. The Company and Williams each hereby irrevocably and
unconditionally submit to the nonexclusive jurisdiction of any New York State
court or Federal court of the United States of America sitting in New York City,
or any court presiding over a chapter 11 case of the Company, and any appellate
court from any thereof, but solely in any action or proceedings to enforce this
Agreement. Each of the parties hereto agrees that a final judgment in any such
action or proceeding will be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.

     15. Counterparts. This Agreement may be executed in any number of
counterparts and by different parties hereto in separate counterparts and by
facsimile, with the same effect as if all parties had signed the same document.
All such counterparts are to be deemed an original, construed together and
constitute one and the same instrument.

     16. Severability. Any term or provision of this Agreement that is invalid
or unenforceable in any jurisdiction, will, as to that jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, the provision will be interpreted
to be only so broad as is enforceable.

     17. Headings. The headings of the paragraphs of this Agreement are inserted
for convenience only and not to affect the interpretation hereof.

     18. Assignment. Except as provided in Section 7 above, either this
Agreement nor the rights or the obligations of either party hereto are
assignable in whole or in part (whether by operation of law or otherwise),
without the written consent of the other party and any attempt to do so in
contravention of this Section 18 will be void.

binding upon the parties hereto and their respective successors and permitted
assigns.
