 [Reverse of the Note] 

THE WILLIAMS COMPANIES, INC. 

2.600% Senior Note due 2031 
 1.
GENERAL 
 This Note is one of a duly authorized issue of Securities (the “Securities”) of The Williams Companies, Inc. (the
“Company,” which term includes any successor Person under the Base Indenture hereinafter referred to), issued and issuable in one or more series under an Indenture, dated as of December 18, 2012, (the “Base
Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee,” which term includes any successor trustee under the Base Indenture), to which Base Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitation of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities issued thereunder and of the
terms upon which said Securities are, and are to be, authenticated and delivered. This Note is one of the series designated on the face hereof as 2.600% Senior Notes due 2031 (the “Notes”) which was issued under the Fourth
Supplemental Indenture to the Base Indenture dated as of March 2, 2021 (the “Supplemental Indenture”, together with the Base Indenture, the “Indenture”) and which is initially limited to $900,000,000 in
principal amount. Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Indenture. 

The Company promises to pay interest on the principal amount of this Note at the rate of 2.600% per annum from [Insert for Initial Notes
– “March 2, 2021”] until the Stated Maturity, unless earlier repurchased, redeemed or otherwise cancelled. The Company will pay interest semiannually on March 15 and September 15 of each year (each an “Interest
Payment Date”). Interest on the Notes will accrue from the most recent Interest Payment Date on which interest has been paid or duly provided for or, if no interest has been paid or duly provided for, from [Insert for Initial Notes
“March 2, 2021”]; provided that if there is no existing default in the payment of interest, and if this Note is authenticated between a regular record date set forth on the face hereof (each a “Regular Record
Date”) and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date shall be [Insert for Initial Notes
“September 15, 2021”] and interest accrued from [Insert for Initial Notes – “March 2, 2021”] shall be payable on such date. The interest so payable, and punctually paid or duly provided for, on any Interest Payment
Date will, as provided in the Indenture, be paid to the Person in whose name this Note is registered at the close of business on the Regular Record Date next preceding such Interest Payment Date. Except as otherwise provided in the Indenture, any
such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Note is registered at the close of business on a Special
Record Date for the payment of such defaulted interest to be fixed by the Trustee, notice whereof shall be given to the Holders of the Notes not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner
not inconsistent with the requirements of any securities exchange, if any, on which the Notes shall be listed, and upon such notice as may be required by any such exchange, all as more fully provided in the Indenture. Payments of interest on the
Notes will include interest accrued to but excluding the respective Interest Payment Dates. 

  
 A-4 













 Further, the Company shall pay interest on overdue principal and premium, if any, from time
to time on demand at a rate of 2.600% per annum; it shall pay interest on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed
on the basis of a 360-day year of twelve 30-day months. 

If an Interest Payment Date, the Stated Maturity or a Redemption Date falls on a day that is not a Business Day, the required payment of
principal, premium, if any, and interest due on that date shall be made on the next succeeding Business Day as if made on the date that payment was due, and no interest shall accrue for the period from and after the Interest Payment Date, Stated
Maturity or such Redemption Date, as the case may be, to the date of that payment on the next succeeding Business Day. 
 2. REDEMPTION 

The Notes are subject to redemption upon not less than 10 or more than 60 days’ notice to the Holders of the Notes to be redeemed as
provided in the Indenture, at any time or from time to time prior to December 15, 2030, as a whole or in part, at the election of the Company, at a Redemption Price, as calculated by the Company, equal to the greater of: (i) 100% of the
principal amount of the Notes being redeemed, plus accrued and unpaid interest, if any, to, but not including, the Redemption Date and (ii) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments
of principal of, and interest that would be due on, the Notes to be redeemed if the Notes matured on December 15, 2030 (not including any portion of payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a
semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 20 basis points plus accrued and unpaid interest, if
any, to, but not including, the Redemption Date. 
 In addition, the Notes are subject to redemption upon not less than 10 or more than 60
days’ notice to the Holders of the Notes to be redeemed as provided in the Indenture, at any time or from time to time on or after December 15, 2030, as a whole or in part, at the election of the Company, at a Redemption Price, as
calculated by the Company, equal to 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest, if any, to, but not including, the Redemption Date. 

If less than all the Notes are to be redeemed, selection of Notes for redemption will be made [Insert for Global Notes – by the
Depositary by lot or other means in accordance with the Depositary’s procedures] [Insert for a Definitive Security—by the Trustee in accordance with the Depositary’s procedures]. Unless the Company defaults in payment of such
Redemption Price, from and after the Redemption Date, the Notes or portions thereof called for redemption will cease to bear interest, and the Holders thereof will have no right in respect of such Notes except the right to receive the Redemption
Price thereof. 

  
 A-5 













 3. DEFEASANCE 

The Indenture contains provisions for defeasance of (a) the entire indebtedness of this Note and (b) certain restrictive covenants
upon compliance by the Company with certain conditions set forth therein. 
 4. DEFAULTS AND REMEDIES 

If an Event of Default with respect to the Notes shall occur and be continuing, the principal of the Notes may be declared due and payable, or
in the circumstances described in the Indenture, shall automatically become due and payable, in the manner and with the effect provided in the Indenture. At any time after such declaration of acceleration or automatic acceleration with respect to
the Notes has been made or has occurred, but before a judgment or decree for payment of money has been obtained by the Trustee as provided in the Indenture, if all Events of Default with respect to the Notes have been cured or waived (other than the
non-payment of principal of the Notes which has become due solely by reason of such declaration of acceleration or automatic acceleration) and certain other conditions have been complied with, then and in
every such case, the Holders of a majority in aggregate principal amount of the Outstanding Notes may, by written notice to the Company and to the Trustee, rescind and annul such declaration or automatic acceleration and its consequences on behalf
of all of the Holders of Notes, but no such rescission or annulment shall extend to or affect any subsequent default or impair any right consequent thereon. 

As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any proceeding,
judicial or otherwise, with respect to the Indenture, or for the appointment of a receiver or trustee or for any other remedy thereunder, unless (a) such Holder shall have previously given the Trustee written notice of a continuing Event of
Default with respect to the Notes, (b) (i) in the case of an Event of Default specified in clause (1), (2), (5) or (6) of Section 501 of the Indenture, Holders of not less than 25%, or (ii) in the case of an Event of Default
specified in clause (3) or (4) of Section 501 of the Indenture, Holders of not less than a majority, in aggregate principal amount of the Outstanding Notes shall have made written request to the Trustee to institute proceedings in respect
of such Event of Default in its own name as Trustee hereunder, (c) such Holders shall have offered the Trustee indemnity satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request,
(d) for 60 days after its receipt of such notice, the Trustee shall not have received from the Holders of a majority in principal amount of the Notes at the time Outstanding under the Indenture a direction inconsistent with such request, and
(e) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity shall have failed to institute any such proceeding. The foregoing shall not apply to certain suits described in the Indenture, including any suit
instituted by the Holder of this Note for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed or provided for herein. 

5. NONIMPAIRMENT 
 No reference
herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest, if any, on this Note at
the times, place and rate, and in the coin or currency, herein prescribed. 

  
 A-6 













 6. DENOMINATIONS; TRANSFER AND EXCHANGE

registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any
taxes and fees required by law or permitted by the Indenture. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. 

7. SUCCESSOR OBLIGORS

successor assumes all the obligations of its predecessor under the Notes and the Indenture in accordance with the terms of the Indenture, the predecessor will be released from those obligations, except in the case of a lease. 

8. TRUSTEE DEALINGS WITH THE COMPANY 

The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with
the Company, its Subsidiaries or their respective Affiliates as if it were not the Trustee. 
 9. AUTHENTICATION 

This Note will not be valid until authenticated by the manual, facsimile or electronic signature of the Trustee or an Authenticating Agent.

 10. NO RECOURSE AGAINST OTHERS 

The owners of the Company’s Capital Stock and the Company’s incorporators, directors and officers will not be liable for the
Company’s obligations under the Notes, the Indenture or for any claim based on, or in respect of, such obligations. By accepting a Note, each Holder of that Note will have agreed to Section 117 of the Base Indenture and waived and released
any such liability on the part of the owners of the Company’s Capital Stock and the Company’s incorporators, directors and officers. The waiver and release are part of the consideration for issuance of the Notes. 

11. CUSIP NUMBERS

the consent of the Holders of not less than a majority in aggregate principal amount of the Notes affected by such supplemental indenture (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes)
and any existing default or Event of Default with respect to the Notes may be waived with the consent of the Holders of not less than a majority in aggregate principal amount of the Outstanding Notes, except a continuing default in the payment of
the principal of, or any premium or interest on the Notes, or in respect of a covenant or provision of the Indenture which cannot be modified or amended without the consent of the Holder of each Outstanding Note. Without the consent of any Holder of
Notes, the Company and the Trustee, at any time and from time to time, may enter into one or more supplemental indentures as provided in the Indenture, subject to the exceptions set forth therein.
