                  WHEREAS, the Issuer has executed and delivered the Original
Indenture to the Trustee to provide for the issuance from time to time of its
senior, unsecured notes, debentures or other evidences of indebtedness (the
"Securities"), to be issued in one or more series as in the Original Indenture
provided;

                  WHEREAS, pursuant to the terms of the Original Indenture, the
Issuer desires to make, execute and deliver to the Trustee this Eighth
Supplemental Indenture to the Original Indenture in order to establish the form

"Notes"), under the Original Indenture in the aggregate principal amount of
$1,400,000,000;

                  WHEREAS, all things necessary to make the Notes, when executed
by the Issuer and authenticated and delivered by the Trustee and issued upon the
terms and subject to the conditions hereinafter and in the Indenture set forth,
against payment therefor, the valid, binding and legal obligations of the Issuer
and to make this Eighth Supplemental Indenture a valid, binding and legal

covenants contained in the Original Indenture and this Eighth Supplemental

                                   ARTICLE I

                                  DEFINED TERMS

                  Section 1.1 Defined Terms. Except as otherwise expressly
provided in this Eighth Supplemental Indenture or in the form of Note set forth

                                   ARTICLE II

                               TERMS OF THE NOTES

                  Section 2.1 Establishment of the Notes. There is hereby
authorized a series of Securities designated the 9.25% Notes due March 15, 2004,
limited in aggregate principal amount to $1,400,000,000 (except as provided in
Section 2.3(2) of the Original Indenture). The Issuer may, without the consent
of the Holders of the Notes, provided that no Event of Default shall have
occurred and be continuing, issue additional Notes in such principal amount as
shall be determined by or pursuant to a Board Resolution and having the same
ranking and the same interest rate, maturity or other terms as the Notes
originally issued hereunder, which together with said additional Notes shall
constitute a single series of Securities under the Indenture. The Notes shall be
substantially in the form set forth in Exhibit A hereto and shall include
substantially the legends set forth on the face thereof.

                  Section 2.2 Terms of the Notes. The terms and provisions of
the Notes as set forth in Exhibit A are hereby incorporated in and expressly
made part of this Eighth Supplemental Indenture.

                  The Notes will mature and the principal thereof will be due
and payable, together with all accrued and unpaid interest thereon, on March 15,
2004.

                  The Notes shall bear interest at the rate of 9.25% per annum.

                  The amount of interest payable on the Notes will be computed
on the basis of a 360-day year consisting of twelve 30-day months.

                  Payment of the principal of (and premium, if any) and interest
on the Notes will be made at the office or agency of the Issuer maintained for
that purpose in the Borough of Manhattan, the City and State of New York, in
such coin or currency of the United States of America as at the time of payment
is legal tender for the payment of public and private debts and in immediately
available funds; provided, however, that at the option of the Issuer payment of
interest may be made by wire transfer of immediately available funds to an
account of the Person entitled thereto as such account shall be provided to the
Trustee at least 15 days prior to the relevant payment date or by check in New
York Clearinghouse Funds mailed to the address of the person entitled thereto as
such address shall appear in the registry books of the Issuer.

                  Initially the Notes will be issued in global form registered
in the name of Cede & Co. (as nominee for The Depository Trust Company (the
"Depositary"), the initial securities depositary for the Notes), and may bear
such legends as the Depositary may reasonably request. So long as the Notes are
outstanding in global form registered in the name of the Depositary or its
nominee, all payments of principal, premium, if any, and interest will be made
by the Issuer in immediately available funds.

                  No service charge shall be made for the registration of
transfer or exchange of the Notes; provided, however, that the Issuer may
require payment of a sum sufficient to cover any

                                       2
<PAGE>

tax or other governmental charge that may be imposed in connection with the
exchange or transfer.

                  The Notes shall not be superior in right of payment to, and
shall rank pari passu with, all other unsecured and unsubordinated Indebtedness
of the Issuer.

                  The Notes shall be issued in minimum denominations of $1,000
or any integral multiple of $1,000 over such denomination.

                  Section 2.3 Global Notes. Unless and until it is exchanged for
the Notes in registered form, one or more global Notes in principal amount equal
to the aggregate principal amount of all outstanding Notes ("Global Notes") may
be transferred, in whole but not in part, only to the Depositary or a nominee of
the Depositary, or to a successor Depositary selected or approved by the Issuer
or to a nominee of such successor Depositary.

                  If at any time (i) the Depositary notifies the Issuer that it
is unwilling or unable to continue as a Depositary for the Global Notes and no
successor Depositary shall have been appointed within 90 days after such
notification, (ii) the Depositary ceases to be a clearing agency registered
under the Securities Exchange Act of 1934 at any time the Depositary is required
to be so registered to act as such Depositary and no successor Depositary shall
have been appointed within 90 days after the Issuer's becoming aware of the
Depositary's ceasing to be so registered, (iii) the Issuer, in its sole
discretion, determines that the Global Notes shall be exchangeable for Notes in
definitive registered form or (iv) there shall have occurred and be continuing
an Event of Default, the Issuer will execute, and subject to Article Five of the
Original Indenture, the Trustee, upon written notice from the Issuer, will
authenticate and deliver the Notes in definitive registered form without
coupons, in authorized denominations, and in an aggregate principal amount equal
to the principal amount of the Global Note in exchange for such Global Note.

                  Upon exchange of the Global Note for such Notes in definitive
registered form without coupons, in authorized denominations, the Global Note
shall be cancelled by the Trustee. Such Notes in definitive registered form
issued in exchange for the Global Note shall be registered in such names and in
such authorized denominations as the Depositary, pursuant to instructions from
its direct or indirect participants or otherwise, shall instruct the Trustee.
The Trustee shall deliver such Securities to the Depositary for delivery to the
Persons in whose names such Securities are so registered.

                                  ARTICLE III

                  Section 3.1 Execution Of Notes. The Notes shall be executed as
follows:

         The Notes shall be signed on behalf of the Issuer by its Chairman of
the Board, its President, one of its Vice Presidents or its Treasurer, under its
corporate seal which may, but need not, be attested. Such signatures may be the
manual or facsimile signatures of the present or any future such officers. The
seal of the Issuer may be in the form of a facsimile thereof and may be
impressed, affixed, imprinted or otherwise reproduced on the Notes.
Typographical and other minor errors or defects in any such reproduction of the
seal or any such signature shall not affect

                                       3
<PAGE>

the validity or enforceability of any Note that has been duly authenticated and
delivered by the Trustee.

         In case any officer of the Issuer who shall have signed any of the
Notes shall cease to be such officer before the Note so signed shall be
authenticated and delivered by the Trustee or disposed of by the Issuer, such
Note nevertheless may be authenticated and delivered or disposed of as though
the person who signed such Note had not ceased to be such officer of the Issuer;
and any Note may be signed on behalf of the Issuer by such persons as, at the
actual date of the execution of such Note, shall be the proper officers of the
Issuer, although at the date of the execution and delivery of this Eighth
Supplemental Indenture any such person was not such an officer.

                                   ARTICLE IV

                                SUNDRY PROVISIONS

                  Section 4.1 Execution, Authentication and Delivery of the
Notes. Notes in the aggregate principal amount of $1,400,000,000, or in such
greater principal amount as shall be permitted by Section 2.1, may, upon
execution of this Eighth Supplemental Indenture, or from time to time
thereafter, be executed by the Issuer and delivered to the Trustee for
authentication, and the Trustee shall thereupon authenticate and deliver said
Notes upon an Issuer Order without any further action by the Issuer.

                  Section 4.2 Paying Agent and Security Registrar. Bank One
Trust Company, N.A. will be the paying agent and registrar for the Notes.

                  Section 4.3 Trustee Not Responsible for Recitals. The recitals

of the Issuer, and the Trustee assumes no responsibility for their correctness.
The Trustee makes no representations as to the validity or sufficiency of this
Eighth Supplemental Indenture.

                  Section 4.4 Incorporation of Indenture. The Original
Indenture, as supplemented by this Eighth Supplemental Indenture, is in all
respects ratified and confirmed, and this Eighth Supplemental Indenture shall be
deemed part of the Indenture in the manner and to the extent herein and therein
provided.

                  Section 4.5 Governing Law. This Eighth Supplemental Indenture
shall be deemed to be a contract under the laws of the State of New York and for

                           360-day year consisting of twelve 30-day months) at a
                           rate equal to the sum of 50 basis points plus the
                           Adjusted Treasury Rate on the third Business Day
                           prior to the redemption date, as calculated by an
                           Independent Investment Banker.

         "Adjusted Treasury Rate" means, with respect to any redemption date:

      o     the yield, under the heading which represents the average for the
            immediately preceding week, appearing in the most recently published
            statistical release designated "H.15(519)" or any successor
            publication which is published weekly by the Board of Governors of
            the Federal Reserve System and which establishes yields on actively
            traded U.S. Treasury securities adjusted to constant maturity under
            the caption "Treasury Constant Maturities," for the maturity
            corresponding to the Optional Redemption Comparable Treasury Issue
            (if no maturity is within three months before or after the remaining
            term of the Securities of this series, yields for the two published
            maturities most closely corresponding to the Optional

                                      A-4
<PAGE>

            Redemption Comparable Treasury Issue will be determined and the
            Adjusted Treasury Rate will be interpolated or extrapolated from
            such yields on a straight line basis, rounding to the nearest
            month); or

      o     if such release (or any successor release) is not published during
            the week preceding the calculation date or does not contain such
            yields, the rate per annum equal to the semi-annual equivalent yield
            to maturity of the Optional Redemption Comparable Treasury Issue,
            calculated using a price for the Optional Redemption Comparable
            Treasury Issue (expressed as a percentage of its principal amount)
            equal to the Optional Redemption Comparable Treasury Price for such
            redemption date.

         "Independent Investment Banker" means [Salomon Smith Barney Inc.] and
any successor firm, or if any such firm is unwilling or unable to serve as such,
an independent investment and banking institution of national standing appointed
by the Issuer.

         "Optional Redemption Reference Treasury Dealer" means each of up to
five dealers to be selected by the Issuer, and their respective successors;
provided that if any of the foregoing ceases to be, and has no affiliate that
is, a U.S. government securities dealer (a "Primary Treasury Dealer"), the
Issuer will substitute for it another Primary Treasury Dealer.

         "Optional Redemption Comparable Treasury Issue" means the U.S. Treasury
security selected by an Independent Investment Banker as having a maturity
comparable to the remaining term of the Securities of this series to be redeemed
that would be utilized, at the time of selection and in accordance with
customary financial practice, in pricing new issues of corporate debt securities
of comparable maturity to the remaining term of such Securities or, if, in the
reasonable judgment of the Independent Investment Banker, there is no such
security, then the Optional Redemption Comparable Treasury Issue will mean the
U.S. Treasury security or securities selected by an Independent Investment
Banker as having an actual or interpolated maturity or maturities comparable to
the remaining term of the Securities.

         "Optional Redemption Comparable Treasury Price" means (1) the average
of five Optional Redemption Reference Treasury Dealer Quotations for the
redemption date, after excluding the highest and lowest Optional Redemption
Reference Treasury Dealer Quotations, or (2) if the Independent Investment
Banker obtains fewer than five such Optional Redemption Reference Treasury
Dealer Quotations, the average of all such quotations.

         "Optional Redemption Reference Treasury Dealer Quotations" means, with
respect to each Optional Redemption Reference Treasury Dealer and any redemption
date, the average, as determined by the Independent Investment Banker of the bid
and asked prices for the Optional Redemption Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the Independent Investment Banker at 5:00 p.m., New York City time,
on the third Business Day preceding such redemption date.

         The Issuer will mail notice of redemption at least 30 days but not more
than 60 days before the applicable redemption date to each Holder of the
Securities to be redeemed. If the Issuer elects to partially redeem the
Securities, the Trustee will select in a fair and appropriate manner the
Securities to be redeemed. The Issuer shall give the Trustee notice of the
redemption price shortly after the calculation thereof.

         Upon the payment of the redemption price plus accrued and unpaid
interest, if any, to the date of redemption, interest will cease to accrue on
and after the applicable redemption date on the Securities or portions thereof
called for redemption.

                  Usury. The interest rate on the Securities of this series
shall in no event be higher than the maximum rate permitted by New York law as
the same may be modified by United States law of general application.

                  Defeasance. The Indenture contains provisions for defeasance
of (a) the entire Indebtedness evidenced by this Security and (b) certain
restrictive covenants upon compliance by the Issuer with certain conditions set
forth therein.

                  Events of Default. If an Event of Default with respect to
Securities of this series shall occur and be continuing, the principal of the
Securities of this series may be declared due and payable in the manner and with
the effect provided in the Indenture.

                  Amendment to Indenture; Waiver of Defaults. The Indenture
permits the Issuer and the Trustee, with the consent of the Holders of not less
than a majority in aggregate principal amount of the Securities of each series
issued under the Indenture then outstanding and affected, to execute
supplemental indentures adding any provisions to or changing in any manner the
rights of the Holders of each series so affected; provided that the Issuer and
the Trustee may not, without the consent of the Holder of each outstanding
Security affected thereby, (a) extend the final maturity of any such Security,
or reduce the principal amount thereof, or reduce the rate or extend the time of
payment of interest thereon, or reduce any amount payable on redemption or
repayment thereof, or change the currency of payment thereof, or impair or
affect the rights of any Holder to institute suit for the payment; or (b) reduce
the aforesaid percentage in principal amount of Securities. The Indenture
contains provisions permitting the Holders of not less than a majority in
aggregate principal amount of the Securities of all series with respect to which
a default under the Indenture shall have occurred and be continuing (voting as
one class), on behalf of the Holders of all Securities of all such series, to
waive certain past defaults under the Indenture and their consequences with
certain conditions set forth therein. Any such consent or waiver by the Holder
of this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

                  Obligations Unconditional. No reference herein to the
Indenture and no provision of this Security or of the Indenture shall alter or
impair the obligation of the Issuer, which is absolute and unconditional, to pay
the principal of, premium, if any, and interest, if any, on this Security at the
time, place and rate, and in the coin or currency, herein prescribed unless
otherwise agreed between the Issuer and the registered Holder of this Security.

                  Transfer and Exchange. This Security shall be exchangeable for
Securities registered in the names of Persons other than the Depositary with
respect to such series or its nominee only as provided in this paragraph. This
Security shall be so exchangeable if (x) the Depositary notifies the Issuer that
it is unwilling or unable to continue as Depositary for such series or at any
time ceases to be a clearing agency registered as such under the Exchange Act,
or (y) the Issuer executes and delivers to the Trustee an Officers' Certificate
providing that this Security shall be so exchangeable. Securities so issued in
exchange for this Security shall be of the same series, having the same interest
rate, if any, and maturity and having the same terms as this Security, in
authorized denominations and in the aggregate having the same principal amount
as this Security and registered in such names as the Depositary for such Global
Security shall direct. As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of a Security of the series of which
this Security is a part is registrable in the registry books of the Issuer, upon
surrender of this Security for registration of transfer at the office or agency
of the Issuer in any place where the principal of (and premium, if any) and
interest, if any, on this Security are payable, duly endorsed by, or accompanied
by a written instrument of transfer in form satisfactory to the Issuer

                                      A-6
<PAGE>

and the Trustee duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities of this series
and of like tenor, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

                  The Securities of this series are issuable only in registered
form without coupons in minimum denominations of $1,000 or any integral multiple
of $1,000 over such minimum denomination. As provided in the Indenture and
subject to certain limitations therein set forth, Securities of this series are
exchangeable for a like aggregate principal amount of Securities of this series
and of like tenor of a different authorized denomination, as requested by the
Holder surrendering the same.

                  No service charge shall be made for any such registration of
transfer or exchange, but the Issuer may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  Prior to due presentment of this Security for registration of
transfer, the Issuer, the Trustee and any agent of the Issuer or the Trustee may
treat the Person in whose name this Security is registered as the owner hereof
for all purposes, whether or not this Security be overdue, and neither the
Issuer, the Trustee nor any such agent shall be affected by notice to the
contrary.

                  Governing Law. This Security shall be governed by, and
construed in accordance with, the laws of the State of New York.

                  All terms used in this Security which are defined in the
Indenture and not otherwise defined herein shall have the meanings assigned to
them in the Indenture.

                             THE WILLIAMS COMPANIES

         provide as follows:

                  "Subject to Section 7.8, a Participant's Supplemental
                  Retirement Benefit, if any and if vested, shall normally
                  commence to be paid at the same time and shall normally be
                  paid pursuant to the same method of payment as is selected by
                  the Participants under the Pension Plan; however, the
                  Committee, in its sole and absolute discretion, is authorized
                  to approve or reject a Participant's request for a time of
                  commencement of payment or a method of payment under the

2.       In all other respects, the Plan remains unchanged.

IN WITNESS WHEREOF, the Administrative Committee has caused this amendment of
the Plan to be executed this 30th day of March, 1998.
