                              WARRANT AGREEMENT(1)

         THIS AGREEMENT dated as of          between THE WILLIAMS
COMPANIES, INC., a corporation duly organized and existing under the laws of
the State of Delaware (the "Company"), and                , a [bank] [trust
company] duly incorporated and existing under the laws of            , as
Warrant Agent (the "Warrant Agent"),

         Bracketed language here and throughout this Agreement should be
inserted as follows:

         1. If Warrants are immediately detachable from the Offered Securities;
and

         2. If Warrants are detachable from the Offered Securities only after
the Detachable Date.

                                   WITNESSETH:

         [WHEREAS, the Company has entered into an Indenture dated as of
_____________ (the "Senior Indenture") between the Company and ______________,
as Trustee (the "Senior Indenture Trustee"), and an Indenture dated as of
____________ (the "Subordinated Indenture") between the Company and
_____________, as Trustee (the "Subordinated Indenture Trustee") (together, the
"Trustees" or "Trustee" and "Indentures" or "Indenture"), providing for the
issuance from time to time of its unsecured debt securities to be issued in one
or more series as provided in the Indenture; and]

         WHEREAS, the Company proposes to sell [title of such securities being
offered] (the "Offered Securities") with one or more warrants (the "Warrants")
representing the right to purchase [title of such securities purchasable through
exercise of Warrants] (the "Warrant Securities"), the Warrants to be evidenced
by Warrant certificates issued pursuant to this Agreement (the "Warrant
Certificates"); and

         WHEREAS, the Company desires the Warrant Agent to act on behalf of the
Company in connection with the issuance, transfer, exchange, exercise and
replacement of the Warrant Certificates, and in this Agreement wishes to set
forth, among other things, the form and provisions of the Warrant Certificates
and the



--------

        (1) Complete or modify the provisions of this form as appropriate to
reflect the terms of the Warrants and Warrant Securities. Monetary amounts may
be in U.S. dollars in a foreign currency.


<PAGE>


terms and conditions on which they may be issued, transferred, exchanged,
exercised and replaced;

         NOW, THEREFORE, in consideration of the premises and of the mutual
agreements herein contained, the parties hereto agree as follows:

                                    ARTICLE 1
           ISSUANCE OF WARRANTS AND EXECUTION AND DELIVERY OF WARRANT
                                  CERTIFICATES

         SECTION 1.01. Issuance of Warrants. Issuance of Warrants. The Warrants
shall be evidenced by one or more Warrant Certificates. Each Warrant evidenced
thereby shall represent the right, subject to the provisions contained herein
and therein, to purchase [_____ shares of the Warrant Securities] [ aggregate
principal amount of Warrant Securities ] and shall be initially issued in
connection with the issuance of the Offered Securities [1: and shall be
separately transferable immediately thereafter] [2: but shall not be separately
transferable until on and after , (the "Detachable Date")]. The Warrants shall
be initially issued [in units] with the Offered Securities, and each Warrant
[included in such a unit] shall evidence the right, subject to the provisions
contained herein and in the Warrant Certificates, to purchase [_____ shares of
the Warrant Securities] [ aggregate principal amount of Warrant Securities]
[included in such a unit].

         SECTION 1.02. Execution and Delivery of Warrant Certificates. Each
Warrant, whenever issued, shall be evidenced by a Warrant Certificate in
registered form, substantially in the form set forth in Exhibit A hereto, shall
be dated and may have such letters, numbers or other marks of identification or
designation and such legends or endorsements printed, lithographed or engraved
thereon as the officers of the Company executing the same may approve (execution
thereof to be conclusive evidence of such approval) and as are not inconsistent
with the provisions of this Agreement, or as may be required to comply with any
law or with any rule or regulation made pursuant thereto or with any rule or
regulation of any stock exchange on which the Warrants may be listed, or to
conform to usage. The Warrant Certificates shall be signed on behalf of the
Company by its chairman or vice chairman of the Board of Directors, the
president, any managing director or the treasurer of the Company, in each case
under its corporate seal, which may but need not be, attested by its Secretary
or one of its Assistant Secretaries. Such signatures may be manual or facsimile
signatures of such authorized officers and may be imprinted or otherwise
reproduced on the Warrant Certificates. The corporate seal of the Company may be
in the form of a facsimile thereof and may be impressed, affixed, imprinted or
otherwise reproduced on the Warrant Certificates.




                                        2

<PAGE>



         No Warrant Certificate shall be valid for any purpose, and no Warrant
evidenced thereby shall be exercisable, until such Warrant Certificate has been
countersigned by the Warrant Agent by manual signature. Such signature by the
Warrant Agent upon any Warrant Certificate executed by the Company shall be
conclusive evidence, and the only evidence, that the Warrant Certificate so
countersigned has been duly issued hereunder.

         In case any officer of the Company who shall have signed any of the
Warrant Certificates either manually or by facsimile signature shall cease to be
such officer before the Warrant Certificates so signed shall have been
countersigned and delivered by the Warrant Agent as provided herein, such
Warrant Certificates may be countersigned and delivered notwithstanding that the
person who signed such Warrant Certificates ceased to be such officer of the
Company; and any Warrant Certificate may be signed on behalf of the Company by
such persons as, at the actual date of the execution of such Warrant
Certificate, shall be the proper officers of the Company, although at the date
of the execution of this Agreement any such person was not such officer.

         The term "Holder", when used with respect to any Warrant Certificate,
shall mean any person in whose name at the time such Warrant Certificate shall
be registered upon the books to be maintained by the Warrant Agent for that
purpose [2: or, prior to the Detachable Date, any person in whose name at the
time the Offered Security to which such Warrant Certificate is attached is
registered upon the register of the Offered Securities. Prior to the Detachable
Date, the Company will, or will cause the registrar of the Offered Securities
to, make available at all times to the Warrant Agent such information as to
holders of the Offered Securities with Warrants as may be necessary to keep the
Warrant Agent's records up to date.]

         SECTION 1.03. Issuance of Warrant Certificates. Warrant Certificates
evidencing the right to purchase [_____ shares of the Warrant Securities] [an
aggregate principal amount not exceeding aggregate principal amount of Warrant
Securities] (except as provided in Sections 2.03, 3.02 and 4.01) may be executed
by the Company and delivered to the Warrant Agent upon the execution of this
Warrant Agreement or from time to time thereafter. The Warrant Agent shall, upon
receipt of Warrant Certificates duly executed on behalf of the Company,
countersign Warrant Certificates evidencing ___________ Warrants representing
the right to purchase up to [_____shares of the Warrant Securities] [
          aggregate principal amount of Warrant Securities] and shall deliver
such Warrant Certificates to or upon the order of the Company. Subsequent to
such original issuance of the Warrant Certificates, the Warrant Agent shall
countersign a Warrant Certificate only if the Warrant Certificate is issued in
exchange or substitution for one or more previously countersigned Warrant
Certificates or in




                                        3

<PAGE>

connection with their transfer as hereinafter provided or as provided in the
antepenultimate paragraph of Section 2.03.

         Pending the preparation of definitive Warrant Certificates evidencing
Warrants, the Company may execute and the Warrant Agent shall countersign and
deliver temporary Warrant Certificates evidencing such Warrants (printed,
lithographed, typewritten or otherwise produced, in each case in form
satisfactory to the Warrant Agent). Such temporary Warrant Certificates shall be
issuable substantially in the form of the definitive Warrant Certificates but
with such omissions, insertions and variations as may be appropriate for
temporary Warrant Certificates, all as may be determined by the Company with the
concurrence of the Warrant Agent. Such temporary Warrant Certificates may
contain such reference to any provisions of this Warrant Agreement as may be
appropriate. Every such temporary Warrant Certificate shall be executed by the
Company and shall be countersigned by the Warrant Agent upon the same conditions
and in substantially the same manner, and with like effect, as the definitive
Warrant Certificates. Without unreasonable delay, the Company shall execute and
shall furnish definitive Warrant Certificates and thereupon such temporary
Warrant Certificates may be surrendered in exchange therefor without charge
pursuant to and subject to the provisions of Section 4.01, and the Warrant Agent
shall countersign and deliver in exchange for such temporary Warrant
Certificates definitive Warrant Certificates of authorized denominations
evidencing a like aggregate number of Warrants evidenced by such temporary
Warrant Certificates. Until so exchanged, such temporary Warrant Certificates
shall be entitled to the same benefits under this Warrant Agreement as
definitive Warrant Certificates.

                                    ARTICLE 2
                WARRANT PRICE, DURATION AND EXERCISE OF WARRANTS

         SECTION 2.01. Warrant Price.  On          ,      the exercise price of
each Warrant will be        .  During the period from        ,     through and
including , , the exercise price of each Warrant will be [plus [accrued
amortization of the original issue discount] [accrued interest] from , .] On ,
the exercise price of each Warrant will be . During the period from , through
and including , , the exercise price of each Warrant will be [plus [accrued
amortization of the original issue discount] [accrued interest] from , .] [In
each case, the original issue discount will be amortized at a % annual rate,
computed on an annual basis using the "interest" method and using a 360-day year
consisting of twelve 30-day months]. Such exercise price of Warrant Securities
is referred to in this Agreement as the "Warrant Price". [The original issue
discount for each principal amount of Warrant Securities is ].

                                        4

<PAGE>


         SECTION 2.02.  Duration of Warrants.  Subject to Section 4.03(b), each
Warrant may be exercised [in whole but not in part] [in whole or in part] [at
any time, as specified herein, on or after [the date thereof] [       ,    ] and
at or before [time, location] on           ,        (each day during such period
may hereinafter be referred to as an "Exercise Date")] [on [list of specific
dates] (each, an "Exercise Date")], or such later date as the Company may
designate by notice to the Warrant Agent and the Holders of Warrant Certificates
[in registered form and to the beneficial owners of the Global Warrant
Certificate] (the "Expiration Date"). Each Warrant not exercised at or before
[time, location] on the Expiration Date shall become void, and all rights of the
Holder [and any beneficial owners] of the Warrant Certificate evidencing such
Warrant under this Agreement shall cease.

         SECTION 2.03. Exercise of Warrants. During the period specified in
Section 2.02, any whole number of Warrants may be exercised by providing certain
information as set forth on the reverse side of the Warrant Certificates
evidencing such Warrants and by paying in full [in lawful money of the United
States of America] [in applicable currency] [in cash] [by certified check or
official bank check or by bank wire transfer, in each case,] [by bank wire
transfer] [in immediately available funds,] the Warrant Price for each Warrant
exercised [(plus accrued interest, if any, on the Warrant Securities to be
issued upon exercise of such Warrant from and including the Interest Payment
Date (as defined in the Indenture), if any, in respect of such Warrant
Securities immediately preceding the Exercise Date to and including the Exercise
Date (unless the Exercise Date is after the Regular Record Date (as defined in
the Indenture), if any, for such Interest Payment Date, but on or before the
immediately succeeding Interest Payment Date for such Warrant Securities, in
which event no such accrued interest shall be payable in respect of Warrant
Securities to be issued in registered form))] to the Warrant Agent at its
corporate trust office at [address] [or at    ], provided that such exercise is
subject to receipt within five business days of such [payment] [wire transfer]
by the Warrant Agent of the Warrant Certificate evidencing each Warrant
exercised with the form of election to purchase Warrant Securities set forth on
the reverse side of the Warrant Certificate properly completed and duly
executed. [Cashless Exercise Option]

         The date on which payment in full of the Warrant Price (plus any such
accrued interest) is received by the Warrant Agent shall, subject to receipt of
the Warrant Certificate as aforesaid, be deemed to be the date on which the
Warrant is exercised. The Warrant Agent shall deposit all funds received by it
in payment for the exercise of Warrants in an account of the Company maintained
with it (or in such other account as may be designated by the Company) and shall
advise the Company, by telephone or by facsimile transmission or other form of
electronic communication available to both parties, at the end of each day on
which a payment for the exercise of Warrants is received of the amount so
deposited to its




                                        5

<PAGE>


account. The Warrant Agent shall promptly confirm such advice to the Company in
writing.

         If a day on which Warrants may be exercised in the city in which such
Warrants are to be exercised shall be a Saturday or Sunday or a day on which
banking institutions in such city are authorized or required to be closed, then,
notwithstanding any other provision of this Agreement or the Warrant Certificate
evidencing such Warrants, but subject to the limitation that no Warrant may be
exercised after the Expiration Date, the Warrants shall be exercisable on the
next succeeding day which in such city is not a Saturday or Sunday or a day on
which banking institutions in such city are authorized or required to be closed.

         The Warrant Agent shall, from time to time, as promptly as practicable,
advise the Company and the Trustee in writing of (i) the number of Warrants
exercised, (ii) the instructions of each Holder of the Warrant Certificates
evidencing such Warrants with respect to delivery of the Warrant Securities to
be issued upon such exercise, (iii) delivery of any Warrant Certificates
evidencing the balance, if any, of the Warrants remaining after such exercise,
and (iv) such other information as the Company or the Trustee shall reasonably
require.

         As soon as practicable after the exercise of any Warrant, but subject
to receipt by the Warrant Agent of the Warrant Certificate evidencing such
Warrant as provided in this Section, the Company shall issue[, pursuant to the
Indenture, in authorized denominations to or upon the order of the Holder of the
Warrant Certificate evidencing each Warrant,] the Warrant Securities to which
such Holder is entitled, in fully registered form, registered in such name or
names as may be directed by such Holder. If fewer than all of the Warrants
evidenced by such Warrant Certificate are exercised, the Company shall execute,
and an authorized officer of the Warrant Agent shall manually countersign and
deliver, a new Warrant Certificate evidencing the number of such Warrants
remaining unexercised.

         The Company shall not be required to pay any stamp or other tax or
other governmental charge required to be paid in connection with any transfer
involved in the issuance of the Warrant Securities, and in the event that any
such transfer is involved, the Company shall not be required to issue or deliver
any Warrant Security until such tax or other charge shall have been paid or it
has been established to the Company's satisfaction that no such tax or other
charge is due.

                                    ARTICLE 3
            OTHER PROVISIONS RELATING TO RIGHTS OF HOLDERS OF WARRANT

         SECTION 3.01. No Rights as Warrant Securityholder Conferred by Warrant
or Warrant Certificates. No Warrant Certificate or Warrant evidenced thereby
shall entitle the Holder or any beneficial owner thereof to any of the rights of
a holder or beneficial owner of Warrant Securities, including, without
limitation, [the right to receive the payment of principal of (premium, if any)
or interest, if any, on Warrant Securities or to enforce any of the covenants in
the Indenture] [the right to receive dividend payments on the Warrant Securities
or any voting rights].

         SECTION 3.02. Lost, Mutilated, Stolen, or Destroyed Warrant
Certificates. Upon receipt by the Warrant Agent of evidence reasonably
satisfactory to it and the Company of the ownership of and the loss, mutilation,
theft or destruction of any Warrant Certificate and of such security or
indemnity as may be required by the Company and the Warrant Agent to hold each
of them and any agent of them harmless and, in the case of mutilation of a
Warrant Certificate, upon surrender thereof to the Warrant Agent for
cancellation, then, in the absence of notice to the Company or the Warrant Agent
that such Warrant Certificate has been acquired by a bona fide purchaser, the
Company shall execute, and an authorized officer of the Warrant Agent shall
manually countersign and deliver, in exchange for or in lieu of the lost,
mutilated, stolen or destroyed Warrant Certificate, a new Warrant Certificate of
the same tenor and evidencing a like number of Warrants. Upon the issuance of
any new Warrant Certificate under this Section, the Company may require the
payment of a sum sufficient to cover any stamp or other tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Warrant Agent) in connection
therewith. Every substitute Warrant Certificate executed and delivered pursuant
to this Section in lieu of any lost, mutilated, stolen or destroyed Warrant
Certificate shall represent an additional contractual obligation of the Company,
whether or not the lost, stolen or destroyed Warrant Certificate shall be at any
time enforceable by anyone, and shall be entitled to the benefits of this
Agreement equally and proportionately with any and all other Warrant
Certificates duly executed and delivered hereunder. The provisions of this
Section are exclusive and shall preclude (to the extent lawful) all other rights
and remedies with respect to the replacement of lost, mutilated, stolen or
destroyed Warrant Certificates.

         SECTION 3.03. Enforcement of Rights. Notwithstanding any of the
provisions of this Agreement, any Holder of a Warrant Certificate, without the
consent of the Warrant Agent, the Trustee, the holder of any Offered Securities
or the Holder of any other Warrant Certificate, may, in its own behalf and for
its own benefit, enforce, and may institute and maintain any suit, action or
proceeding


                                        7

<PAGE>


against the Company suitable to enforce, or otherwise in respect of, its right
to exercise its Warrants in the manner provided in its Warrant Certificate and
in this Agreement.

         SECTION 3.04. Merger, Consolidation, Conveyance or Transfer. (a) If at
any time there shall be a merger or consolidation of the Company or a conveyance
or transfer of its property and assets substantially as an entirety [as
permitted under the Indenture], then in any such event the successor or assuming
corporation referred to therein shall succeed to and be substituted for the
Company, with the same effect[, subject to the Indenture,] as if it had been
named herein and in the Warrant Certificates as the Company; the Company shall
thereupon, except in the case of a transfer by way of lease, be relieved of any
further obligation hereunder and under the Warrants and the Warrant
Certificates, and the Company as the predecessor corporation, except in the case
of a transfer by way of lease, may thereupon or at any time thereafter be
dissolved, wound up or liquidated. Such successor or assuming corporation may
thereupon cause to be signed, and may issue either in its own name or in the
name of the Company, Warrant Certificates evidencing any or all of the Warrants
issuable hereunder which theretofore shall not have been signed by the Company,
and may execute and deliver Warrant Securities in its own name [,pursuant to the
Indenture,] in fulfillment of its obligations to deliver Warrant Securities upon
exercise of the Warrants. All the Warrants so issued shall in all respects have
the same legal rank and benefit under this Agreement as the Warrants theretofore
or thereafter issued in accordance with the terms of this Agreement as though
all of such Warrants had been issued at the date of the execution hereof. In any
case of any such merger, consolidation, conveyance or transfer, such changes in
phraseology and form (but not in substance) may be made in the Warrant
Certificates representing the Warrants thereafter to be issued as may be
appropriate.

         (b) The Warrant Agent may receive a written opinion of legal counsel
(who shall be acceptable to the Warrant Agent) as conclusive evidence that any
such merger, consolidation, conveyance or transfer complies with the provisions
of this Section and the Indenture.

                  [Add Anti-Dilution provisions as necessary.]

                                    ARTICLE 4
                              EXCHANGE AND TRANSFER

         SECTION 4.01. Exchange and Transfer. (a) [1: Upon] [2: Prior to the
Detachable Date, a Warrant Certificate may be exchanged or transferred only
together with the Offered Security to which such Warrant Certificate was
initially attached, and only for the purpose of effecting, or in conjunction
with, an


                                        8

<PAGE>



exchange or transfer of such Offered Security. Prior to any Detachable Date,
each transfer of the Offered Security, shall operate also to transfer the
related Warrant Certificates. On or after the Detachable Date, upon] surrender
at the corporate trust office of the Warrant Agent at [address] [or      ],
Warrant Certificates evidencing Warrants may be exchanged for Warrant

pay the Warrant Agent the compensation to be agreed upon with the Company for
all services rendered by the Warrant Agent and to reimburse the Warrant Agent
for reasonable out-of-pocket expenses (including reasonable attorneys' fees)

          (b) Agent for the Company. In acting under this Agreement and in
connection with the Warrants and the Warrant Certificates, the Warrant Agent is

          (c) Counsel. The Warrant Agent may consult with counsel satisfactory
to it in its reasonable judgment, and the advice of such counsel shall be full

suffered or omitted by it hereunder in good faith and in accordance with the
advice of such counsel.

          (d) Documents. The Warrant Agent shall be protected and shall incur no
liability for or in respect of any action taken or thing suffered by it in
reliance upon any Warrant Certificate, notice, direction, consent, certificate,
affidavit, statement or other paper or document reasonably believed by it to be

          (e) Certain Transactions. The Warrant Agent, and its officers,
directors and employees, may become the owner of, or acquire any interest in,

hereunder, and, to the extent permitted by applicable law, it or they may engage
or be interested in any financial or other transaction with the Company and may
act on, or as depositary, trustee or agent for, any committee or body of holders
of Warrant Securities or other obligations of the Company as freely as if it
were not the Warrant Agent hereunder. [Nothing in this Warrant Agreement shall
be deemed to prevent the Warrant Agent from acting as Trustee under the
Indenture.]

         (f) No Liability for Interest. The Warrant Agent shall have no
liability for interest on any monies at any time received by it pursuant to any
of the provisions of this Agreement or of the Warrant Certificates.

for the application by the Company of the proceeds of the Warrant Certificates.

the Company in the performance of its covenants or agreements contained herein
or in the Warrant Certificates or in the case of the receipt of any written
demand from a Holder of a Warrant Certificate with respect to such default,
including, without limiting the generality of the foregoing, any duty or
responsibility to initiate or attempt to initiate any proceedings at law or
otherwise or, except as provided in Section 6.02, to make any demand upon the
Company.

all the Warrants have been exercised or are no longer exercisable.

         (b) The Warrant Agent may at any time resign as such by giving written
notice of its resignation to the Company, specifying the desired date on which
its resignation shall become effective; provided, however, that such date shall

the Warrant Agent and appoint a successor Warrant Agent (qualified as aforesaid)
by written instrument in duplicate signed on behalf of the Company and
specifying such removal and the date when it is intended to become effective,
one copy of which shall be delivered to the Warrant Agent being removed and one
copy to the successor Warrant Agent. Any resignation or removal of the Warrant
Agent and any appointment of a successor Warrant Agent shall become effective
upon acceptance of appointment by the successor Warrant Agent as provided in
this subsection (b). In the event a successor Warrant Agent has not been
appointed and accepted its duties within 90 days of the Warrant Agent's notice
of resignation, the Warrant Agent may apply to any court of competent
jurisdiction for the designation of a successor Warrant Agent. Upon its
resignation or removal, the Warrant Agent shall be entitled to the payment by
the Company of the compensation and to the reimbursement of all reasonable
out-of-pocket expenses (including reasonable attorneys' fees) incurred by it
hereunder as agreed to in Section 5.02(a).

           (c) The Company shall remove the Warrant Agent and appoint a
successor Warrant Agent if the Warrant Agent (i) shall become incapable of
acting, (ii) shall be adjudged bankrupt or insolvent, (iii) shall commence a
voluntary case or other proceeding seeking liquidation, reorganization or other
relief with respect to it or its debts under any bankruptcy, insolvency or other
similar law now or hereafter in effect or seeking the appointment of a trustee,

substantial part of its property, (iv) shall consent to, or shall have had
entered against it a court order for, any such relief or to the appointment of
or taking possession by any such official in any involuntary case or other
proceedings commenced against it, (v) shall make a general assignment for the
benefit of creditors or (vi) shall fail generally to pay its debts as they
become due. Upon the appointment as aforesaid of a successor Warrant Agent and
acceptance by it of such appointment, the

law, cease to be Warrant Agent hereunder.

         (d) Any successor Warrant Agent appointed hereunder shall execute,
acknowledge and deliver to its predecessor and the Company an instrument
accepting such appointment hereunder, and thereupon such successor Warrant
Agent, without any further act, deed or conveyance, shall become vested with all
the authority, rights, powers, immunities, duties and obligations of such
predecessor with like effect as if originally named as Warrant Agent hereunder,
and such predecessor shall thereupon become obligated to transfer, deliver and
pay over, and such successor Warrant Agent shall be entitled to receive, all
monies, securities and other property on deposit with or held by such
predecessor as Warrant Agent hereunder.

merged or converted or any corporation with which the Warrant Agent may be
consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Warrant Agent shall be a party, or any corporation to
which the Warrant Agent shall sell or otherwise transfer all or substantially
all the assets and business of the Warrant Agent, provided that it shall be
qualified as aforesaid, shall be the successor Warrant Agent under this
Agreement without the execution or filing of any paper or any further act on the
part of any of the parties hereto.
