 THIS FIRST SUPPLEMENTAL INDENTURE, between Agilent Technologies, Inc., a Delaware
corporation (the “Obligor”), having its principal office at 5301 Stevens Creek Blvd., Santa Clara, California 95051, and Citibank, N.A., as trustee (the “Trustee”), is made and entered into as of this 12th day of March, 2021. 
 RECITALS OF THE OBLIGOR 

WHEREAS, the Obligor and the Trustee executed and delivered an Indenture dated as of March
12th, 2021 (the “Base Indenture”), to provide for the issuance by the Obligor from time to time of debt securities; 

WHEREAS, capitalized terms used herein, not otherwise defined, shall have the same meanings given them in the Base Indenture; 

WHEREAS, pursuant to a board resolution, the Obligor has authorized the issuance of $850 million of its 2.300% Senior Notes due 2031 (the
“Senior Notes”); and 
 WHEREAS, the Obligor desires to establish the terms of the Senior Notes in accordance with
Section 2.01 of the Base Indenture; 
 NOW, THEREFORE, it is mutually agreed as follows: 

ARTICLE I 
 DEFINITIONS 

SECTION 1.01. Definitions. For all purposes of this First Supplemental Indenture, except as otherwise expressly provided or unless
the context otherwise requires: 
 “Base Indenture” has the meaning assigned in the recitals. 

“Change of Control” means the occurrence of any of the following: (1) the direct or indirect sale, transfer, conveyance
or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the assets of the Obligor and its Subsidiaries taken as a whole to any “person” (as that term
is used in Section 13(d) and Section 14(d) of the Securities and Exchange Act of 1934 (the “Exchange Act”)) other than the Obligor or one of its Subsidiaries; (2) the adoption of a plan relating to the Obligor’s
liquidation or dissolution; or (3) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the
Exchange Act) or “group” (within the meaning of Section 13(d) of the Exchange Act) of “persons”, other than the Obligor or its Subsidiaries, becomes the beneficial owner (as defined in Rules
13d-3 and 13d-5 of the Exchange Act), directly or indirectly, of more than 50% of the combined voting power of the Obligor’s Voting Stock or other Voting Stock into
which the Obligor’s Voting Stock is reclassified, consolidated, exchanged or changed, measured by voting power rather than number of shares; provided, however, that (x) a person shall not be deemed beneficial owner of, or to
own beneficially, (A) any securities tendered pursuant to a tender or exchange offer made by or on behalf of such person or any of such person’s affiliates until such tendered securities are accepted for purchase or exchange thereunder, or
(B) any securities if such beneficial ownership (i) arises solely as a result of a revocable proxy delivered in response to a proxy or consent solicitation made pursuant to the applicable rules and regulations under the Exchange Act, and
(ii) is not also then reportable on Schedule 13D (or any successor schedule) under the Exchange Act and (y) a transaction will not be deemed to involve a change of control under this clause (3) if (A) the Obligor becomes a direct or
indirect wholly owned subsidiary of a holding company and (B)(i) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of the Obligor’s Voting
Stock immediately prior to that transaction and each holder holds substantially the same percentage of Voting Stock of such holding company as such holder held of the Obligor’s shares immediately prior to that transaction or (ii) the
Obligor’s Voting Stock outstanding immediately prior to such transaction are converted into or exchanged for, a majority of the Voting Stock of such holding company immediately after giving effect to such transaction. 

  
 1 













 “Change of Control Repurchase Event” means the occurrence of both a Change
of Control and a Ratings Event. 
 “First Supplemental Indenture” means this First Supplemental Indenture dated as of
March 12, 2021 to the Base Indenture between the Obligor and the Trustee, as amended or supplemented from time to time. 

“Fitch” means Fitch Ratings, Inc. and its successors. 

“Investment Grade” means a rating of BBB- or better by Fitch (or its equivalent under
any successor rating categories of Fitch); a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s); and a rating of BBB- or better by S&P (or
its equivalent under any successor rating categories of S&P); or the equivalent investment grade credit rating from any additional Rating Agency or Rating Agencies selected by the Obligor. 

“Make-Whole Amount” means, in connection with any optional redemption of the Senior Notes pursuant to Section 2.06, the
excess, if any, of (i) the aggregate present value as of the Redemption Date of each dollar of principal being redeemed and the amount of interest, calculated by the Obligor, excluding interest accrued to the Redemption Date, that would have
been payable in respect of each dollar if such redemption had been made on the Par Call Date (assuming the Senior Notes matured on the Par Call Date), determined by discounting, on a semi-annual basis, such principal and interest at the Reinvestment
Rate, determined on the third Business Day preceding the Redemption Date, from the respective dates on which the principal and interest would have been payable if such redemption had been made on the Par Call Date, over (ii) the aggregate
principal amount of the Senior Notes being redeemed. The Trustee shall have no obligation to calculate or verify the calculation of the Make-Whole Amount. 

“Moody’s” means Moody’s Investors Service, Inc. and its successors. 

“Obligor Board” means the board of directors of the Obligor. 

“Par Call Date” means December 12, 2030 

“Principal Property” means the Obligor’s principal offices in Santa Clara, California, each manufacturing facility, each
research and development facility and each service and support facility (in each case including associated office facilities) that is real property located within the territorial limits of the United States of America owned by the Obligor or any
wholly owned subsidiaries of the Obligor, except such as the Obligor’s board of directors by resolution determines in good faith (taking into account, among other things, the importance of such property to the business, financial condition and
earnings of the Obligor and its subsidiaries taken as a whole) not to be of material importance to the business of the Obligor and its subsidiaries, taken as a whole. 

“Rating Agency” means each of Fitch, Moody’s and S&P, so long as such entity makes a rating of the Senior Notes
publicly available; provided, however, if any of Fitch, Moody’s or S&P ceases to rate the Senior Notes or fails to make a rating of the Senior Notes publicly available for reasons outside of the control of the Obligor,
the Obligor shall be allowed to designate a “nationally recognized statistical rating organization” within the meaning of Rule 3(a)(62) under the Exchange Act as a replacement agency for the agency that ceased to make such a rating
publicly available. For the avoidance of doubt, failure by the Obligor to pay rating agency fees to make a rating of the Senior Notes shall not be a “reason outside of the control of the Obligor” for the purposes of the preceding sentence.


  
 2 













 “Ratings Event” means a decrease in the ratings of the Senior Notes by one
or more of the Rating Agencies such that the Senior Notes are rated below Investment Grade by all of the Rating Agencies on any date from the date of the public notice of an arrangement that could result in a Change of Control until the end of the 60-day period following public notice of the occurrence of a Change of Control (which period shall be extended so long as the rating of the Senior Notes is under publicly announced consideration for possible
downgrade by any of the Rating Agencies on the 60th day of such period, such extension to last with respect to each such Rating Agency until the date on which such Rating Agency considering such possible downgrade either (x) rates the Senior
Notes below Investment Grade or (y) publicly announces that it is no longer considering the Senior Notes for possible downgrade; provided that no such extension will occur if on such 60th day the Senior Notes are rated Investment Grade
by at least one of such Rating Agencies in question and are not subject to review for possible downgrade by such Rating Agency). 

Notwithstanding the foregoing, a Ratings Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have
occurred in respect of a particular Change of Control (and thus shall not be deemed a Ratings Event for purposes of the definition of Change of Control Repurchase Event hereunder) if the Rating Agencies making the reduction in rating to which this
definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in
respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Ratings Event). 

“Reinvestment Rate” means the yield on treasury securities at a constant maturity corresponding to the remaining life to
maturity (rounded up to the nearest month) of the principal of the Senior Notes being redeemed as of the Redemption Date (which maturity shall be deemed to be the Par Call Date) (the “Treasury Yield”), plus 0.150% for the Senior
Notes being redeemed. For purposes of calculating the Reinvestment Rate, the Treasury Yield will be equal to the arithmetic mean of the yields published in the Statistical Release under the heading “Week Ending” for “U.S. Government
Securities—Treasury Constant Maturities” with a maturity equal to the deemed remaining life to maturity of the Senior Notes being redeemed. However, if no published maturity exactly corresponds to such remaining life, then the Treasury
Yield will be interpolated or extrapolated on a straight-line basis from the arithmetic means of the yields for the next shortest and next longest published maturities. For purposes of calculating the Reinvestment Rate, the most recent Statistical
Release published prior to the date of determination of the Make-Whole Amount will be used. If the format or content of the Statistical Release changes in a manner that precludes determination of the Treasury Yield in the above manner, then the
Treasury Yield will be determined in the manner that most closely approximates the above manner, as the Obligor reasonably determines. 

“Senior Notes” has the meaning assigned in the Recitals. 

“Statistical Release” means the statistical release designated “H.15” or any successor publication that is
published weekly by the Federal Reserve System and that reports yields on actively traded United States government securities adjusted to constant maturities, or, if that statistical release is not published at the time of any required determination
under this First Supplemental Indenture, then another reasonably comparable publication which the Obligor will designate. 

“S&P” means S&P Global Ratings, a division of S&P Global Inc., and its successors. 

“Voting Stock” of any specified Person as of any date means the capital stock of such Person that is at the time entitled to
vote generally in the election of the board of directors of such Person.

60 days prior to the Redemption Date by the Trustee from the Outstanding Senior Notes not previously called for redemption, pro rata, by lot or by such other method as the Trustee shall deem fair and appropriate (including, in the case of
Senior Notes represented by Global Notes, in accordance with the procedures of DTC), and may provide for the selection for redemption of portions (so that any Senior Notes remaining after such selection are equal to the minimum authorized
denomination for the Senior Notes or any integral multiple thereof) of the principal amount of Senior Notes of a denomination larger than the minimum authorized denomination for the Senior Notes. 

(d) The Trustee shall promptly notify the Obligor in writing of the Senior Notes selected for redemption and, in the case of any Senior Notes
selected for partial redemption, the principal amount thereof to be redeemed. 
 (e) For all purposes of this First Supplemental Indenture,
unless the context otherwise requires, all provisions relating to the redemption of Senior Notes shall relate, in the case of any Senior Note redeemed or to be redeemed only in part, to the portion of the principal of such Senior Note which has been

be given to the Holders thereof, by first-class mail, postage prepaid, mailed (or otherwise delivered in accordance with the procedures of DTC) not fewer than 10 nor more than 60 days prior to the Redemption Date, to each such Holder at such
Holder’s last address appearing in the Security Register. All notices of redemption shall state: 
 (i) the Redemption
Date; 
 (ii) the Redemption Price, or if not then ascertainable, the manner of calculating the Redemption Price; 

(iii) the principal amount of Senior Notes to be redeemed and if fewer than all Outstanding Senior Notes are to be redeemed,
the identification (and, in the case of partial redemption, the respective principal amounts) of the Senior Notes to be redeemed from the Holder to whom the notice is given and that on and after the Redemption Date, upon surrender of such Senior
Note, a new Senior Note or Senior Notes in the aggregate principal amount equal to the unredeemed portion thereof shall be issued in accordance with Section 2.06(j); 

(iv) that on the Redemption Date the Redemption Price shall become due and payable upon each Senior Note called for redemption,
and that interest, if any, thereon shall cease to accrue from and after said date; 
 (v) the place where Senior Notes called
for redemption are to be surrendered for payment of the Redemption Price, which shall be the office or agency maintained by the Obligor pursuant to Section 9.02 of the Base Indenture;

 Notice of redemption of Senior Notes shall be given by
the Obligor with a copy to the Trustee or, at the Obligor’s request, by the Trustee in the name and at the expense of the Obligor; provided, however, that if the Obligor requests the Trustee to give such notice, it shall provide
an execution version of such notice to the Trustee at least five Business Days before such notice is required to be sent to the Holders (or such shorter period as shall be acceptable to the Trustee). 

(g) Notice of any redemption of Senior Notes pursuant to this Section 2.06 may, at the Obligor’s discretion, be given subject to one
or more conditions precedent, including, but not limited to, completion of a corporate transaction that is pending (such as an equity or equity-linked offering, an incurrence of indebtedness or an acquisition or other strategic transaction involving
a change of control in the Obligor or another entity). If any redemption is subject to satisfaction of one or more conditions precedent, the applicable notice of redemption shall describe each such condition, and such notice may be rescinded in the
event that any or all such conditions shall not have been satisfied or otherwise waived on or prior to the Business Day immediately preceding the relevant Redemption Date. The Obligor shall notify Holders and the Trustee of any such rescission as
soon as practicable after it determines that such conditions precedent will not be able to be satisfied or the Obligor shall not be able or willing to waive such conditions precedent. Once notice of redemption is mailed or sent, subject to the
satisfaction of any conditions precedent provided in the notice of redemption, the Senior Notes called for redemption will become due and payable on the Redemption Date and at the applicable Redemption Price as set forth in this Section 2.06.


  
 5 













 (h) On or prior to 11:00 a.m., New York City time, on any Redemption Date, the Obligor shall
deposit with the Trustee or with a Paying Agent (or, if the Obligor is acting as its own Paying Agent, segregate and hold in trust as provided in Section 9.03 of the Base Indenture) an amount of money sufficient to pay the Redemption Price of
all the Senior Notes which are to be redeemed on that date. 
 (i) On and after the Redemption Date, interest will cease to accrue on the
Senior Notes or any portion thereof called for redemption, unless the Obligor defaults in the payment of the Redemption Price and accrued interest, if any. Upon surrender of such Senior Notes for redemption in accordance with the notice, such Senior
Notes shall be paid by the Obligor at the Redemption Price. Any installment of interest due and payable on or prior to the Redemption Date shall be payable to the Holders of such Senior Notes registered as such on the relevant Record Date according
to the terms and the provisions of Section 2.06 of the Base Indenture. If any Senior Note called for redemption shall not be so paid upon surrender thereof for redemption, the principal shall, until paid, bear interest from the Redemption Date
at the rate prescribed therefor by the Senior Note. 
 (j) Any Senior Note that is a Definitive Note that is to be redeemed only in part
shall be surrendered at the office or agency maintained by the Obligor pursuant to Section 9.02 of the Base Indenture (with, if the Obligor or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory
to the Obligor and the Trustee duly executed by, the Holder thereof or the Holder’s attorney duly authorized in writing) and the Obligor shall execute and upon receipt of an Authentication Order, the Trustee shall authenticate and deliver to
the Holder of such Senior Note without service charge and at the expense of the Obligor, a new Senior Note or Senior Notes in certificated form, of any authorized denomination as requested by such Holder in aggregate principal amount equal to and in
exchange for the unredeemed portion of the principal of such Senior Note so surrendered. 
 SECTION 2.07. Change of Control
Repurchase. (a) If a Change of Control Repurchase Event occurs, unless the Obligor has exercised its right to redeem the Senior Notes as set forth in Section 2.06, the Obligor shall be required to make an offer to each Holder of the
Senior Notes to repurchase all or any part (in excess of $2,000 and in integral multiples of $1,000) of that Holder’s Senior Notes at a repurchase price in cash equal to 101% of the aggregate principal amount of the Senior Notes repurchased
plus any accrued and unpaid interest on the Senior Notes repurchased to, but not including, the date of repurchase. 
 (b) Within 30 days
following any Change of Control Repurchase Event or, at the option of the Obligor, prior to any Change of Control, but after the public announcement of the Change of Control or event that may constitute the Change of Control, the Obligor shall send
a notice to each Holder, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering to repurchase the Senior Notes on the repurchase date specified in
the notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is sent. The notice shall, if sent prior to the date of consummation of the Change of Control, state that the offer to purchase is
conditioned on a Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice. 
 (c) The Obligor
shall comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations to the extent those laws and regulations are applicable in connection with the repurchase
of the Senior Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with this Section 2.07 or numbered paragraph 8 of the Senior Notes, the Obligor shall
comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 2.07 or numbered paragraph 8 of the Senior Notes by virtue of compliance with such securities laws or
regulations. 

  
 6 













 (d) On the repurchase date following a Change of Control Repurchase Event, the Obligor
shall, to the extent lawful: 
 (i) accept for payment all the Senior Notes or portions of the Senior Notes properly tendered
pursuant to its offer; 
 (ii) deposit with the Paying Agent an amount equal to the aggregate purchase price in respect of
all the Senior Notes or portions of the Senior Notes properly tendered; and 
 (iii) deliver or cause to be delivered to the
Trustee the Senior Notes properly accepted, together with an Officer’s Certificate stating the aggregate principal amount of Senior Notes being purchased by the Obligor. 

(e) The Paying Agent shall promptly send to each Holder of Senior Notes properly tendered the purchase price for the Senior Notes, and upon
receipt of an Authentication Order, the Trustee shall promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Senior Note equal in principal amount to any unpurchased portion of any Senior Notes surrendered.

 (f) The Obligor shall not be required to make an offer to repurchase the Senior Notes upon a Change of Control Repurchase Event if a third
party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Obligor and such third party purchases all Senior Notes properly tendered and not withdrawn under its offer. 

(g) Should the Obligor choose to exercise its rights under Section 3.02 of the Base Indenture, it shall no longer be obligated to make an
offer to repurchase the Senior Notes following a Change of Control Repurchase Event. 
 SECTION 2.08. Issue Date. The Issue Date
of the Senior Notes is March 12, 2021. 
 SECTION 2.09. Issue Price. The issue price of the Senior Notes issued on the

SECTION 2.10. Definitive and Global Notes. The Senior Notes are issuable in whole or in part in the form of Definitive Notes or as
one or more Global Notes in accordance with the Base Indenture, and the Depositary for such Global Notes shall be DTC. 
 SECTION 2.11.
Denomination. The Senior Notes shall be issued in registered form in denominations of $2,000 and integral multiples of $1,000 in excess thereof. 

SECTION 2.12. Further Issuances. The Obligor may issue an unlimited principal amount of additional Senior Notes; provided
that, any such additional Senior Notes shall have identical terms as the Outstanding Senior Notes, other than with respect to the date of issuance, issue price, first Interest Payment Date, interest accrual date and amount of interest payable on the
first Interest Payment Date applicable thereto; provided, further, that any such additional Senior Notes may be consolidated and form a single series with, and will have the same terms as to ranking, redemption, waivers, amendments or
otherwise as, the Outstanding Senior Notes and will vote together as one class on all matters with respect to the Senior Notes; provided, further, that any additional Senior Notes may only bear the same CUSIP and/or ISIN number as the
Outstanding Senior Notes if they would be fungible for United States federal tax purposes with such Outstanding Senior Notes. 

SECTION 2.13. Defeasance and Discharge of Covenants upon Deposit of Moneys, U.S. Government Obligations. (a) Sub-clause (b) of the first paragraph of Section 3.02 of the Base Indenture is hereby supplemented to add after “9.07” thereof:

 7 













 (b) The last sentence of the third to last paragraph of Section 3.02 of the Base
Indenture is hereby supplemented to add to the end thereof: “and the Obligor shall no longer be obligated to make an offer to repurchase Senior Notes under Section 2.07 of the First Supplemental Indenture upon the occurrence of a Change of
Control Repurchase Event (as defined in the First Supplemental Indenture, dated March 12, 2021, between the Obligor and the Trustee).” 

SECTION 2.14. Events of Default. (a) In addition to the Events of Default set forth in Section 4.01 of the Base
Indenture, the Senior Notes shall include the following additional Event of Default designated as clause (8) of such Section, which shall be deemed an Event of Default under Section 4.01 of the Base Indenture: 

“(8) a failure by the Obligor to repurchase Senior Notes tendered for repurchase following the occurrence of a Change of Control
Repurchase Event in conformity with Section 2.07 of the First Supplemental Indenture, dated March 12, 2021, between the Obligor and the Trustee.” 

(b) Notwithstanding the Events of Default set forth in Section 4.01 of the Base Indenture, the Event of Default set forth as clause
(7) of such Section shall not be applicable to the Senior Notes and shall not be deemed an Event of Default with respect to the Senior Notes. 

SECTION 2.15. Limitation on Liens. In addition to the exceptions to the limitations on liens restrictions set forth in
Section 9.06 of the Base Indenture, the Senior Notes shall include the following additional exception designated as clause (11) of such Section: 

“(11) liens existing on the date of the First Supplemental Indenture, dated March 12, 2021, between the Obligor and the
Trustee.” 
 SECTION 2.16. Counterpart Originals. This First Supplemental Indenture may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. The words “execution,”
“signed,” “signature,” “delivery,” and words of like import in or relating to this First Supplemental Indenture or any document to be signed in connection with this First Supplemental Indenture, including execution of
the Senior Notes and authentication thereof by the Trustee, shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a
manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, and the parties hereto consent to conduct the transactions contemplated hereunder by electronic means. All notices,
approvals, consents, requests and any communications hereunder must be in writing (provided that any communication sent to Trustee hereunder that is required to be signed must be in the form of a document that is signed manually or by way of a
digital signature provided by DocuSign (or such other digital signature provider as specified in writing to Trustee by the Obligor)), in English. The Obligor agrees to assume all risks arising out of the use of using digital signatures and
electronic methods to submit communications to Trustee, including without limitation the risk of Trustee acting on unauthorized instructions, and the risk of interception and misuse by third parties. 

SECTION 2.17. Trustee. The recitals contained herein and in the Senior Notes shall be taken as the statements of the Obligor, and the
Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this First Supplemental Indenture or the Senior Notes, except that the Trustee represents that it is duly authorized

1. Interest 
 AGILENT TECHNOLOGIES, INC.,

per annum shown above. The Obligor shall pay interest semi-annually on March 12 and September 12 of each year, beginning on September 12, 2021. Interest on this Senior Note shall accrue from the most recent date to which interest has
been paid or duly provided for or, if no interest has been paid or duly provided for, from March 12, 2021 until the principal hereof is due. Interest shall be computed on the basis of a 360-day year of
twelve 30-day months. The Obligor shall pay interest on overdue principal at the rate borne by this Senior Note, and it shall pay interest on overdue installments of interest at the same rate to the extent
lawful. 
 2. Method of Payment 
 The
Obligor shall pay interest on this Senior Note (except defaulted interest) to the Persons who are registered Holders at the close of business on the Record Date. Holders must surrender this Senior Note to a Paying Agent to collect principal

Note. The Obligor will make all payments in respect of any certificated Senior Note (including principal, premium, if any, and interest) at the office of the Paying Agent, except that, at the option of the Obligor, payment of interest may be made by
mailing a check to the registered address of each Holder thereof or, upon request of a Holder of at least $1,000,000 aggregate principal amount of Senior Notes, by wire transfer to an account located in the United States by the payee. 

3. Paying Agent and Registrar

of the provisions of the Indenture as necessary to permit or facilitate the defeasance and discharge of Senior Notes; (xi) to make any other change that would not adversely affect the Holders of the Senior Notes in any material respect;
(xii) to make any change necessary to comply with any requirement of the Commission in connection with the qualification of the Indenture under the Trust Indenture Act; and (xiii) to conform the Indenture to the section entitled

 14. Defaults and Remedies 

If any Event of Default (other than an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Obligor)
with respect to this Senior Note occurs and is continuing, then either the Trustee or the Holders of not less than 25% in aggregate principal amount of the Outstanding Senior Notes may declare the principal of all Outstanding Senior Notes, and the
interest to the date of acceleration, if any, accrued thereon, to be immediately due and payable by notice in writing to the Obligor 












 
(and to the Trustee if given by Holders) specifying the Event of Default. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Obligor occurs, then
the principal amount of all the Senior Notes then Outstanding and interest accrued thereon, if any, will become and be immediately due and payable without any declaration or other act on the part of the Trustee or the Holders of the Senior Notes, to
the fullest extent permitted by applicable law. 
 Under certain circumstances, the Holders of a majority in principal amount of the
Outstanding Senior Notes may rescind any such acceleration with respect to the Senior Notes and its consequences. 
 No Holder of this
Senior Note may institute any action, unless and until: (i) such Holder has given the Trustee written notice of a continuing Event of Default with respect to the Senior Notes; (ii) the Holders of at least 25% in aggregate principal amount
of the Outstanding Senior Notes have made a written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; (iii) such Holder or Holders has or have offered the Trustee such
indemnity and/or security satisfactory to the Trustee against the losses, costs, expenses and liabilities to be incurred in compliance with such request; (iv) the Trustee has failed to institute any such proceeding for 60 days after its
receipt of such notice, request and offer of indemnity and/or security; and (v) no inconsistent direction has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate
principal amount of the Outstanding Senior Notes. These limitations do not apply to a suit instituted by a Holder of any Senior Notes for enforcement of payment of the principal of, and premium, if any, or interest on, such Senior Notes on or after
the respective due dates expressed in such Senior Notes. 
 15. Trustee Dealings with the Obligor 

Subject to certain limitations imposed by the Trust Indenture Act, the Trustee under the Indenture, in its individual or any other capacity,
may become the owner or pledgee of this Senior Note and may otherwise deal with the Obligor with the same rights it would have if it were not Trustee. 

16. Authentication 
 This Senior Note
shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Senior Note. 

17. Governing Law 
 THIS SENIOR NOTE
SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. 
 18. CUSIP and ISIN Numbers

charge to the Holder a copy of the Indenture which has in it the text of this Senior Note.
