“Guarantor”), and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”), as follows:

 3. The limit upon the aggregate
principal amount of the Notes that may be authenticated and delivered under the Indenture (except for the Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Notes pursuant to
Section 2.08, 2.09, 2.12, 2.17, 3.07 or 9.05 of the Indenture and except for any Notes which, pursuant to Section 2.04 or 2.17 of the Indenture, are deemed never to have been authenticated and delivered thereunder) is $500,000,000;
provided, however, that the authorized aggregate principal amount of the Notes may be increased before or after the issuance of any Notes by a Board Resolution (or action pursuant to a Board Resolution) to such effect; provided further,

4. The Notes shall be issued upon original issuance in whole in the form of one or more Global Securities (the “Global Notes”). The
Depository Trust Company and the Trustee are hereby designated as the Depositary and the Security Custodian, respectively, for the Global Notes under the Indenture.

of Global Notes (including principal, premium, if any, and interest) shall be made by wire transfer of immediately available funds to the accounts specified by the Holder of such Notes. In all other cases, at the option of the Company, payment of
interest may be made by check mailed to the address of the person entitled thereto as such address shall appear in the register of the Notes maintained by the Registrar. 

10. The Paying Agent and Registrar for the Notes initially shall be the Trustee. 

11. Prior to December 1, 2027 (the “Par Call Date”), the Notes are subject to redemption pursuant to Article III of the
Indenture, in whole or in part, from time to time, at the option of the Company, in principal amounts of $2,000 and integral multiples of $1,000 above such amount, upon not less than 10 nor more than 60 days’ prior notice as provided in the
Indenture, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places), determined by the Company, equal to the greater of the following amounts plus, in either case, accrued and unpaid interest on the
principal amount of the Notes to be redeemed to, but not including, the Redemption Date: (i) (a) the sum of the present values of the remaining scheduled payments of principal and interest on the principal amount of the Notes to be redeemed
discounted to the Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months)
at the Treasury Rate plus 25 basis points, less (b) interest accrued to the Redemption Date; and (ii) 100% of the principal amount of the Notes to be redeemed. On or after December 1, 2027, the Notes are subject to redemption pursuant to
Article III of the Indenture, in whole or in part, from time to time, at the option of the Company, in principal amounts of $2,000 and integral multiples of $1,000 above such amount, at a redemption price equal to 100% of the principal amount of the
Notes to be redeemed, plus accrued and unpaid interest thereon to, but not including, the Redemption Date. 
 “Business Day”
means, any day that is not a Saturday, a Sunday or a day on which banking institutions in any of The City of New York, New York; Houston, Texas or a Place of Payment (as defined in the Indenture) are authorized or obligated by law, regulation or
executive order to remain closed. 
 “Remaining Life” means, with respect to any Redemption Date, the period from such Redemption
Date to the Par Call Date. 

  
 2 












 “Treasury Rate” means, with respect to any Redemption Date, the yield determined
by the Company in accordance with the following two paragraphs: 
 The Treasury Rate shall be determined by the Company after 4:15 p.m., New
York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the applicable Redemption Date based upon the yield or yields
for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any
successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, the Company
shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the Remaining Life; or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two
yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the
Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining
Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the
relevant number of months or years, as applicable, of such Treasury constant maturity from the applicable Redemption Date. 
 If on the
third Business Day preceding the Redemption Date H.15 or any successor designation or publication is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity
at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States
Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity
date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more
United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon
the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the
applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three
decimal places. 
 12. The Company shall have no obligation to redeem, purchase or repay Notes pursuant to any sinking fund or analogous
provision or at the option of a Holder thereof. 
 13. Each Global Note shall bear the legend set forth on the face of the Form of Note.


  
 3 












 14. The initial offering and sale of the Notes shall not be registered under the Securities
Act of 1933, as amended (the “Securities Act”), or any state securities laws. The Notes shall be entitled to the benefit of Section 4.03(b) of the Indenture (and accordingly constitute Rule 144A Securities, as defined in the
Indenture). 
 15. For so long as any of the Notes constitute “restricted securities” within the meaning of Rule 144(a)(3)
promulgated under the Securities Act, the Company or the Guarantor shall, if the Company or the Guarantor is not then subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, furnish to any Holder or beneficial owner of
such Notes, or to any prospective purchaser of such Notes designated by such Holder or beneficial owner, in each case upon the written request of such Holder, beneficial owner or prospective purchaser, the information required to be provided
pursuant to Rule 144A(d)(4) promulgated under the Securities Act. 
 16. Notes of each series initially sold to “qualified
institutional buyers” (as defined in Rule 144A) (“QIBs”) in the United States (the “Rule 144A Notes”) shall be issued in the form of one or more permanent Global Securities of such series, without interest coupons, including
appropriate legends as set forth herein (the “Rule 144A Global Notes” of such series), deposited with the Trustee, as Security Custodian for the Depositary. Notes of each series initially sold to
non-U.S. persons outside the United States in offshore transactions in reliance on Regulation S under the Securities Act (the “Regulation S Notes”) shall be issued in the form of one or more
permanent Global Securities of such series, without interest coupons, including appropriate legends as set forth herein (the “Regulation S Global Notes” of such series and, together with the Rule 144A Global Notes of such series, the
“Global Notes”), deposited with the Trustee, as Security Custodian for the Depositary. 
 17. (a) Except as permitted by
Section 17(b) or Section 18(c) hereof, each Global Note (and all Notes issued in exchange therefor or in substitution thereof) shall bear the following legend (the “Private Placement Legend”) and shall be subject to the transfer
restrictions set forth therein (each defined term in the legend being defined as such for purposes of the legend only):

Section 17(a) hereof), and (ii) the provisions relating to Additional Interest (as defined in Annex A hereto) will be eliminated). 

“Registration Rights Agreement” means (i) the Registration Rights Agreement, dated May 5, 2022 by and among the
Company, the Guarantor and the Dealer Managers party thereto with respect to the Initial Notes, and (ii) with respect to any Additional Notes, any registration rights agreements or joinder to the Registration Rights Agreement between the
Company and the Dealer Managers party thereto, relating to rights given by the Company to the purchasers of Additional Notes to register such Additional Notes or exchange them for Notes registered under the Securities Act.

accompanied by the following additional information and documents, as applicable, upon which the Security Custodian may conclusively rely: 

(i) if such Notes are being delivered to the Security Custodian by a Holder for registration in the name of such Holder,
without transfer, a certification from such Holder to that effect (in substantially the form of Annex B hereto); 

(ii) if such Notes are being transferred (1) to a QIB in accordance with Rule 144A, (2) pursuant to an exemption from

Depositary therefor, which shall include restrictions on transfer comparable to those set forth therein and herein to the extent required by the Securities Act.

Notes so issued shall not bear such legend. If Notes are issued upon the registration or transfer, exchange or replacement of Notes bearing the Private Placement Legend, or if a request is made to remove the Private Placement Legend on a Note, the
Notes so issued shall bear the Private Placement Legend, or the Private Placement Legend shall not be removed, as the case may be, unless there is delivered to the Company and the Trustee such satisfactory evidence, which may include an Opinion of
Counsel of recognized standing licensed to practice law in the State of New York and experienced in matters involving the Securities Act, as may be reasonably required by the Company or the Trustee that neither the Private Placement Legend nor the
restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A, Rule 144 or Regulation S, that such Notes are not “restricted securities” within the meaning of Rule 144 or
that such Notes were transferred pursuant to an effective registration statement under the Securities Act. Upon provision of such satisfactory evidence, the Trustee, at the direction of the Company, shall authenticate and deliver a Note that does
not bear the Private Placement Legend. If a Private Placement Legend is removed from the face of a Note and the Note is subsequently held by an Affiliate of the Company, the Private Placement Legend shall be reinstated. 

(d) Notwithstanding anything herein to the contrary, neither the Trustee nor the Security Custodian shall have any responsibility to receive
any letters, opinions or certifications, nor any responsibility to monitor compliance with any transfer restrictions, in connection with any transfer or exchange of any beneficial interest in a Global Security for a beneficial interest in the same
Global Security.

directives, guidelines and interpretations promulgated by competent authorities) in effect from time to time (“Applicable Tax Law”) to which a foreign financial institution, issuer, trustee, paying agent, holder or other institution is or
has agreed to be subject related to the Indenture and the Notes, the Company and the Guarantor agree (i) to provide to the Trustee sufficient information about holders or other applicable parties and/or transactions related to the Indenture and

 [FORM OF REVERSE OF SECURITY] 

PHILLIPS 66 COMPANY 
 3.750% SENIOR
NOTE DUE 2028 
 FULLY AND UNCONDITIONALLY GUARANTEED BY 

PHILLIPS 66 
 This Security is one of a duly
authorized issue of 3.750% Senior Notes due 2028 (the “Securities”) of Phillips 66 Company, a Delaware corporation (the “Company”). 

1. Interest. The Company promises to pay interest on the principal amount of this Security at 3.750% per annum from March 1, 2022
until maturity [and shall pay the Additional Interest payable pursuant to the Registration Rights Agreement referred to below. References herein to “interest” include any such Additional Interest then owing]. The Company will pay interest
semiannually on March 1 and September 1 of each year (each an “Interest Payment Date”), or if any such day is not a Business Day, on the next succeeding Business Day. Interest on the Securities shall accrue from the most recent
Interest Payment Date on which interest has been paid or, if no interest has been paid, from March 1, 2022; provided that if there is no existing Default in the payment of interest, and if this Security is authenticated between a record
date referred to on the face hereof (each, a “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 September 1, 2022. The Company shall pay interest on overdue principal and premium (if any) from time to time at a rate equal to the interest rate then in effect; it shall pay interest on overdue installments of interest (without
regard to any applicable grace periods) from time to time 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. 
 2. Additional Interest. If, under the terms of the Registration Rights
Agreement, dated May 5, 2022, by and among the Company, Phillips 66, a Delaware corporation (the “Guarantor”), and Barclays Capital Inc., J.P. Morgan Securities LLC, and RBC Capital Markets, LLC, a Registration Default (as defined
therein) occurs with respect to this Security, the interest rate on this Security shall be increased by (i) 0.25% per annum for the first 90-day period beginning on the day immediately following such
Registration Default and (ii) an additional 0.25% per annum with respect to each subsequent 90-day period, in each case until and including the date such Registration Default ends, up to a maximum
increase of 1.00% per annum (any such interest being referred to herein as “Additional Interest”). 
 3. Method of Payment.
The Company shall pay interest on the Securities (except defaulted interest) to the Persons who are registered Holders of Securities at the close of business on the Record Date next preceding the Interest Payment Date, even if such Securities are
canceled after such Record Date and on or before such Interest Payment Date. The Holder must surrender this Security to a Paying Agent to collect principal payments. The Company 

  
 A-5 












 
shall pay the principal of, premium (if any) on and interest on the Securities in money of the United States of America that at the time of payment is legal tender for payment of public and
private debts. Such amounts shall be payable at the offices of the Trustee (as defined below), provided that at the option of the Company, the Company may pay such amounts (1) by wire transfer with respect to Global Securities or
(2) by check payable in such money mailed to a Holder’s registered address with respect to any Securities. 
 4. Paying Agent
and Registrar. Initially, U.S. Bank Trust Company, National Association (the “Trustee”), the trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent, Registrar, co-registrar or additional paying agent without notice to any Holder. The Company, the Guarantor or any Subsidiary of the Company may act in any such capacity. 

5. Guarantee. The Guarantor unconditionally guarantees to the Holders from time to time of the Securities, upon the terms and subject
to the conditions set forth in the Indenture (as defined below), (a) the full and prompt payment of the principal of and any premium on the Securities when and as the same shall become due, whether at the Stated Maturity thereof, by acceleration,
redemption or otherwise, and (b) the full and prompt payment of any interest on the Securities when and as the same shall become due, subject to any applicable grace period. The Guarantee constitutes a guarantee of payment and not of
collection. In the event of a default in the payment of principal of or any premium on the Securities when and as the same shall become due, whether at the Stated Maturity thereof, by acceleration, call for redemption or otherwise, or in the event
of a default in the payment of any interest on the Securities when and as the same shall become due, subject to any applicable grace period, each of the Trustee and the Holders of the Securities shall have the right to proceed first and directly
against the Guarantor under the Indenture without first proceeding against the Company or exhausting any other remedies which the Trustee or such Holder may have and without resorting to any other security held by it. 

6. Indenture. The Company issued the Securities under an Indenture, dated as of May 5, 2022 (the “Indenture”), among the
Company, the Guarantor and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “TIA”), as in effect on the
date of execution of the Indenture. The Securities are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of such terms and for the definitions of capitalized terms used but not defined herein. The
Securities are unsecured general obligations of the Company limited to $500,000,000 in aggregate principal amount; provided, however, that the authorized aggregate principal amount of the Securities may be increased before or after the
issuance of any Securities by a Board Resolution (or action pursuant to a Board Resolution) to such effect; provided further, however, that the authorized aggregate principal amount of the Securities may be increased only if the additional
Securities issued will be fungible with the original Securities for United States federal income tax purposes. The Indenture provides for the issuance of other series of debt securities (including the Securities, the “Debt Securities”)
thereunder. 

  
 A-6 












 7. Denominations, Transfer, Exchange. The Securities are in registered form without
coupons in minimum denominations of $2,000 and any integral multiples of $1,000 above such amount. The transfer of Securities may be registered and Securities 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 to pay any taxes and fees required by law or permitted by the Indenture. Neither the Company, the Trustee nor the Registrar shall be required to register the
transfer or exchange of (a) any Security selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part, or (b) any Security during the period beginning 15 Business Days before the mailing
of notice of redemption of Securities to be redeemed and ending at the close of business on the day of mailing. 
 8. Persons Deemed
Owners. The registered Holder of a Security shall be treated as its owner for all purposes. 
 9. Redemption. Prior to
December 1, 2027 (the “Par Call Date”), the Securities are subject to redemption pursuant to Article III of the Indenture, in whole or in part, from time to time, at the option of the Company, in principal amounts of $2,000 and
integral multiples of $1,000 above such amount, upon not less than 10 nor more than 60 days’ prior notice as provided in the Indenture, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places),
determined by the Company, equal to the greater of the following amounts plus, in either case, accrued and unpaid interest on the principal amount of the Securities to be redeemed to, but not including, the Redemption Date: (i) (a) the sum of
the present values of the remaining scheduled payments of principal and interest on the principal amount of the Notes to be redeemed discounted to the Redemption Date (assuming the Securities matured on the Par Call Date) on a semi-annual basis
(assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points, less (b) interest accrued to the Redemption Date; and (ii)
100% of the principal amount of the Securities to be redeemed. On or after December 1, 2027, the Securities are subject to redemption pursuant to Article III of the Indenture, in whole or in part, from time to time, at the option of the
Company, in principal amounts of $2,000 and integral multiples of $1,000 above such amount, at a redemption price equal to 100% of the principal amount of the Securities to be redeemed, plus accrued and unpaid interest thereon to, but not including,
the Redemption Date. 
 “Business Day” means, any day that is not a Saturday, a Sunday or a day on which banking institutions in
any of The City of New York, New York; Houston, Texas or a Place of Payment (as defined in the Indenture) are authorized or obligated by law, regulation or executive order to remain closed. 

“Remaining Life” means, with respect to any Redemption Date, the period from such Redemption Date to the Par Call Date. 

  
 A-7 












 “Treasury Rate” means, with respect to any Redemption Date, the yield determined
by the Company in accordance with the following two paragraphs: 
 The Treasury Rate shall be determined by the Company after 4:15 p.m., New
York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the applicable Redemption Date based upon the yield or yields
for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any
successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, the Company
shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the Remaining Life; or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two
yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the
Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining
Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the
relevant number of months or years, as applicable, of such Treasury constant maturity from the applicable Redemption Date. 
 If on the
third Business Day preceding the Redemption Date H.15 or any successor designation or publication is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity
at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States
Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity
date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more
United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon
the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the
applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three
decimal places. 

  
 A-8 












 10. Amendments and Waivers. Subject to certain exceptions and limitations, the
Indenture or the Securities may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the then outstanding Securities of all series affected by such amendment or supplement (acting as one class),
and any existing or past Default or Event of Default under, or compliance with any provision of, the Indenture may be waived (other than any continuing Default or Event of Default in the payment of the principal of, premium (if any) on or interest
on the Securities) by the Holders of at least a majority in principal amount of the then outstanding Securities of any series or of all series (acting as one class) in accordance with the terms of the Indenture. Without the consent of any Holder,
the Company, the Guarantor and the Trustee may amend or supplement the Indenture or the Securities or waive any provision of either: (i) to cure any ambiguity, omission, defect or inconsistency; (ii) if required, to provide for the
assumption of the obligations of the Company or the Guarantor under the Indenture in the case of the merger, consolidation or sale, lease, conveyance, transfer or other disposition of all or substantially all of the assets of the Company or the
Guarantor; (iii) to provide for uncertificated Securities in addition to or in place of certificated Securities or to provide for the issuance of bearer Securities (with or without coupons); (iv) to provide any security for, or to add any
guarantees of or additional obligors on, the Securities or the related Guarantees; (v) to comply with any requirement in order to effect or maintain the qualification of the Indenture under the TIA; (vi) to add to the covenants of the
Company or the Guarantor for the benefit of the Holders of the Securities, or to surrender any right or power conferred by the Indenture upon the Company or the Guarantor; (vii) to add any additional Events of Default with respect to all or any
series of the Debt Securities; (viii) to change or eliminate any of the provisions of the Indenture, provided that no outstanding Security is adversely affected in any material respect; (ix) to establish the form or terms of Securities of
any series; (x) to supplement any of the provisions of the Indenture to such extent as shall be necessary to permit or facilitate the defeasance and discharge of the Securities pursuant to the Indenture, provided that no interest of any Holders
of Securities is adversely affected in any material respect; or (xi) to evidence and provide for the acceptance of appointment under the Indenture by a successor Trustee with respect to the Securities and to add to or change any of the
provisions of the Indenture as shall be necessary to provide for or facilitate the administration of the trusts thereunder by more than one Trustee, pursuant to the requirements of the Indenture. 

The right of any Holder to participate in any consent required or sought pursuant to any provision of the Indenture (and the obligation of the
Company or the Guarantor to obtain any such consent otherwise required from such Holder) may be subject to the requirement that such Holder shall have been the Holder of record of any Securities with respect to which such consent is required or
sought as of a date identified by the Company or the Guarantor in a notice furnished to Holders in accordance with the terms of the Indenture. 

Without the consent of each Holder affected, the Company may not (i) reduce the amount of Debt Securities whose Holders must consent to
an amendment, supplement or waiver; (ii) reduce the rate of or change the time for payment of interest, including default interest, on any Security; (iii) reduce the principal of or premium on or any mandatory sinking fund payment with
respect to, or change the Stated Maturity of, any Security or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof pursuant to the
Indenture; (iv) reduce the premium, if any, payable upon the redemption of any Security or change the time at which any Security may or shall be redeemed; (v) change any obligation of the Issuer or a Guarantor to pay


  
 A-9 












 
Additional Amounts with respect to any Security; (vi) change the coin or currency in which any Security or any premium, interest or Additional Amounts with respect thereto is payable;
(vii) impair the right to institute suit for the enforcement of any payment of principal of or premium (if any) or interest on any Security, except as provided in the Indenture; (viii) make any change in the percentage of principal amount
of Debt Securities necessary to waive compliance with certain provisions of the Indenture or make any change in the provision for modification; or (ix) waive a continuing Default or Event of Default, each as defined in the Indenture, in the
payment of principal of or premium (if any) or interest on the Securities. 
 A supplemental indenture that changes or eliminates any
covenant or other provision of the Indenture which has expressly been included solely for the benefit of one or more particular series of Debt Securities under the Indenture, or which modifies the rights of the Holders of Debt Securities of such
series with respect to such covenant or other provision, shall be deemed not to affect the rights under the Indenture of the Holders of Debt Securities of any other series. 

11. Defaults and Remedies. Events of Default are defined in the Indenture and generally include: (i) default for 30 days in
payment of any interest on the Securities; (ii) default in any payment of principal of or premium, if any, on the Securities when due and payable; (iii) default by the Company or the Guarantor in compliance with any of its other covenants
or agreements in, or provisions of, the Securities or in the Indenture which shall not have been remedied within 90 days after written notice by the Trustee or by the holders of at least 25% in principal amount of the Securities then outstanding
(or, in the event that other Debt Securities issued under the Indenture are also affected by the default, then 25% in principal amount of all outstanding Debt Securities so affected); or (iv) certain events involving bankruptcy, insolvency or
reorganization of the Company or the Guarantor. If an Event of Default occurs and is continuing, the Trustee by notice to the Company and the Guarantor, or the Holders of at least 25% in principal amount of the then outstanding Securities of the
series affected by such Event of Default (or, in the case of an Event of Default described in clause (iii) above, if outstanding Debt Securities of other series are affected by such default, then at least 25% in principal amount of the then
outstanding Debt Securities so affected) by notice to the Company, the Guarantor and the Trustee, may declare the principal of and interest on all the Securities to be immediately due and payable, except that in the case of an Event of Default
arising from certain events of bankruptcy, insolvency or reorganization of the Company or the Guarantor, all outstanding Debt Securities under the Indenture become due and payable immediately without further action or notice. The amount due and
payable upon the acceleration of any Security is equal to 100% of the principal amount thereof plus accrued interest to the date of payment. Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may
require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Securities may direct the Trustee in its exercise of any trust
or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal, premium or interest) if it determines that withholding notice is in their interests. The Company and the Guarantor must
furnish annual compliance certificates to the Trustee. 

  
 A-10 












 12. Discharge Prior to Maturity. The Indenture with respect to the Securities shall
be discharged and canceled upon the payment of all of the Securities and shall be discharged except for certain obligations upon the irrevocable deposit with the Trustee of any combination of funds and U.S. Government Obligations sufficient for such
payment. 
 13. Trustee Dealings with Company and Guarantor. The Trustee, in its individual or any other capacity, may become the
owner or pledgee of Securities and may make loans to, accept deposits from, and perform services for the Company, the Guarantor or any of their respective Affiliates, and may otherwise deal with the Company, the Guarantor or any such Affiliates, as
if it were not Trustee. 
 14. No Recourse Against Others. A director, officer, employee, stockholder, partner or other owner of the
Company, the Guarantor or the Trustee, as such, shall not have any liability for any obligations of the Company under the Securities, for any obligations of the Guarantor under the Guarantee or for any obligations of the Company, the Guarantor or
the Trustee under the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting a Security waives and releases all such liability. The waiver and release shall be part of the
consideration for the issue of Securities. 
 15. Authentication. This Security shall not be valid until authenticated by the manual
signature of the Trustee or an authenticating agent. 
 16. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee
on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities as a convenience to the Holders of the Securities. No representation is made as to the accuracy of such numbers as printed on the
Securities and reliance may be placed only on the other identification numbers printed thereon. 
 17. Abbreviations. Customary
