&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(II) The Company may redeem the 2027 Notes at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 5 basis points, less (b) interest accrued to, but not including, the date of redemption, and

For purposes of this Section 2(g), the following terms have the following meanings:

"<u>Par Call Date</u>" means (a) with respect to the 2028 Notes, October 15, 2028 (one month prior to the 2028 Maturity Date), (b) with respect to the 2030 Notes, October 15, 2030 (one month prior to the 2030 Maturity Date), (c) with respect to the 2033 Notes, December 15, 2032 (two months prior to the 2033 Maturity Date), (d) with respect to the 2036 Notes, November 15, 2035 (three months prior to the 2036 Maturity Date) and (e) with respect to the 2055 Notes, May 15, 2055 (six months prior to the 2055 Maturity Date).

"<u>Treasury Rate</u>" 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 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) ("H.15 TCM"). 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 period from the redemption date to the Par Call Date (the "<u>Remaining Life</u>"); 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 redemption date.

If on the third business day preceding the redemption date H.15 TCM 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.

The Company's actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary's procedures) at least 10 days but not more than 60 days before the redemption date to each Holder of Notes to be redeemed.

In the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal amount of the Note to be redeemed. A new note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the Holder of the Note upon surrender for cancellation of the original Note. For so long as the Notes are held by DTC (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the depositary.

Unless the Company defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the Notes or portions thereof called for redemption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(IV) Each series of the Notes will be subject to a "special mandatory redemption" in the event that (i) the CCS Acquisition (as defined below) is not consummated on or prior to the later of (x) August 3, 2026 (the "<u>Outside Date</u>") or (y) the date that is five Business Days after any later date to which the parties to the Purchase Agreement (as defined below) may agree to extend the Outside Date in the Purchase Agreement or to which the Outside Date is automatically extended pursuant to the terms of the Purchase Agreement (the "<u>Special Mandatory Redemption End Date</u>"), or (ii) the Company notifies the Trustee in writing that the Company will not pursue consummation of the CCS Acquisition. The Company refers to each of such events as a "special mandatory redemption event." If a special mandatory redemption event occurs, the Company will be required to redeem the outstanding Notes of each series at the "special mandatory redemption price" equal to 101% of the principal amount thereof plus accrued and unpaid interest from the date of initial issuance, or the most recent date to which interest has been paid or provided for, whichever is later, to, but not including, the special mandatory redemption date. The "special mandatory redemption date" will be selected by the Company and will be a date no later than ten Business Days following the occurrence of the special mandatory redemption event. Unless the Company defaults in payment of the special mandatory redemption price, on and after such special mandatory redemption date, interest on the Notes will cease to accrue.

In the event that the Company becomes obligated to redeem the Notes of each series pursuant to the special mandatory redemption, the Company, either directly or through the Trustee at the Company's expense, direction and on the Company's behalf, will cause a notice of the special mandatory redemption to be sent, with a copy to the Trustee, not later than five Business Days after the occurrence of the special mandatory redemption event to each Holder of the Notes of each series at their registered address. Such notice will also specify the special mandatory redemption date. If funds sufficient to pay the special mandatory redemption price of the Notes of each series to be redeemed on the special mandatory redemption date are deposited with the Paying Agent on or before such special mandatory redemption date, and certain other conditions are satisfied, on and after such special mandatory redemption date, the Notes of each series to be redeemed will cease to bear interest and all rights under the Notes of each series to be redeemed shall terminate.

Upon the consummation of the CCS Acquisition, the foregoing provisions regarding special mandatory redemption will cease to apply. For the purposes of the foregoing, the CCS Acquisition will be deemed consummated if the closing under the Purchase Agreement occurs, including after giving effect to any amendments or modifications to the Purchase Agreement or waivers thereunder acceptable to the Company.

For purposes of this Section 2(g)(IV), the following definitions apply:

"<u>CCS Business</u>" means the Connectivity and Cable solutions businesses (specifically the Data Center Connectivity Solutions business, the Broadband Communications business and the Building Connectivity Solutions business) of CommScope Holding Company, Inc.

"<u>CCS Acquisition</u>" means the proposed acquisition of the CCS Business by the Company, pursuant to the Purchase Agreement.

"<u>Purchase Agreement</u>" means the Purchase Agreement dated August 3, 2025, by and between the Company and CommScope Holding Company, Inc., as such agreement may be amended or modified or any provision thereof waived.

(h) Except as described under Section 2(g) above, the Notes will not be redeemable by the Company prior to maturity and will not be entitled to the benefit of any sinking fund.

(i) If a Change of Control Repurchase Event (as defined below) occurs, unless the Company has exercised its right to redeem all of the Notes as described under Section 2(g) above, each Holder of the Notes shall have the right to require the Company to repurchase all or any part (equal to $2,000 and integral multiples of $1,000 in excess thereof) of such Holder's Notes pursuant to the offer described below (the "<u>Change of Control Offer</u>"), at a purchase price in cash equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase (subject to the right of Holders of record on the relevant Interest Record Date to receive interest due on the relevant Interest Payment Date).

Within 30 days following any Change of Control Repurchase Event, or at the Company's option, prior to any Change of Control but after the public announcement of the pending Change of Control, the Company shall send, by first class mail, a notice to each Holder, with a copy to the Trustee, which notice will govern the terms of the Change of Control Offer, stating:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) that such Change of Control Repurchase Event has occurred or is pending and that such Holder has the right
to require the Company to repurchase such Holder's Notes at a purchase price in cash equal to 101% of the principal amount of the
Notes plus accrued and unpaid interest, if any, to, but not including, the date of repurchase (subject to the right of Holders of record
on the relevant Interest Record Date to receive interest due on the relevant Interest Payment Date) (the " <u>Change of Control Payment</u> ");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) if such notice is mailed prior to the date of consummation of the Change of Control, that the Change of
Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) the date of repurchase (which shall be no earlier than 30 days nor later than 60 days from the date the
Change of Control Offer is mailed) (the " <u>Change of Control Payment Date</u> "); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) the procedures determined by the Company, consistent with the Indenture, that a Holder must follow in
order to have its Notes repurchased.

On the Change of Control Payment Date, the Company shall, to the extent lawful:

or portions of Notes so tendered; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers'
Certificate stating the aggregate principal amount of Notes or portions of Notes being repurchased by the Company and, to the extent applicable,
an executed new note or notes evidencing any unpurchased portion of any Note or Notes surrendered for which the Trustee shall authenticate
and deliver a new note or notes as provided below.

The Trustee shall promptly as practicable mail, or shall cause the Paying Agent to promptly mail, to each Holder of Notes so tendered the Change of Control Payment for such Notes, and the Trustee shall promptly as practicable authenticate and mail (or cause to be transferred by book entry) to each Holder a new note equal in principal amount to any unpurchased portion of the Notes surrendered, if any, *provided* that each such new note shall be in a principal amount of $2,000 and integral multiples of $1,000 in excess thereof.

If the Change of Control Payment Date is on or after an Interest Record Date and on or before the related Interest Payment Date, any accrued and unpaid interest, if any, shall be paid to the Person in whose name the Note is registered at the close of business on such Interest Record Date, and no additional interest shall be payable to Holders who tender pursuant to the Change of Control Offer.

The Company shall not be required to make the Change of Control Offer upon a Change of Control Repurchase Event if a third party makes an offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Indenture applicable to the Change of Control Offer to be made by the Company and repurchases all Notes validly tendered and not withdrawn under such offer.

The Company shall comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws or regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions in this Section 2(i), the Company shall comply with those securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Offer provisions in this Section 2(i) by virtue of any such conflict.

For purposes of this Section 2(i), the following terms have the following meanings:

(REVERSE OF NOTE)

AMPHENOL CORPORATION

FLOATING RATE NOTES DUE 2027

This Global Note designated on the face hereof as Floating Rate Notes due 2027 (the "**Notes**") is a duly authorized issue of securities of the Company issued and issuable in one or more series under an indenture, dated as of March 16, 2023 (the "**Base Indenture**"), between the Company and U.S. Bank Trust Company, National Association, as trustee (the "**Trustee**," which term includes any successor trustee under such indenture), to such indenture, as supplemented by an Officers' Certificate dated as of November 10, 2025 establishing the terms of the Notes (the "**Officers' Certificate**," and together with the Base Indenture, the "**Indenture**"), 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. Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Indenture.

The Notes will bear interest at a floating rate per annum, reset quarterly on each Interest Payment Date (as defined herein), equal to Compounded SOFR, plus 0.53%. In no event will the interest on the Notes be less than zero. Interest on the Notes will be payable quarterly in arrears on February 15, May 15, August 15 and November 15 of each year, commencing on February 15, 2026, and at maturity (each such date, an "**Interest Payment Date**"), to Holders of record on the date that is 15 calendar days prior to each Interest Payment Date (the "**Interest Record Dates**"), whether or not a Business Day. Interest on the Notes will accrue from and including the most recent Interest Payment Date or, if no interest has been paid, from the settlement date of the Notes. If the February 15, May 15, August 15 or November 15 of any year is not a Business Day, then the next succeeding Business Day will be the applicable Interest Payment Date and interest on the Notes will be paid on such next succeeding Business Day (unless such next succeeding Business Day falls in the succeeding calendar month, in which case the applicable Interest Payment Date will be the Business Day immediately preceding such February 15, May 15, August 15 or November 15, and interest on the Notes will be paid on such immediately preceding Business Day). If the Stated Maturity of the Notes is not a Business Day, the payment of principal of, and interest on, the Notes will be made on the next succeeding Business Day, and no interest will accrue for the period from and after the Stated Maturity.

The "**initial Interest Period**" means the period from and including the settlement date of the Notes to, but excluding, the first Interest Payment Date. Thereafter, each "**Interest Period**" means the period from and including a Interest Payment Date to, but excluding, the immediately succeeding Interest Payment Date (such succeeding Interest Payment Date, the "**Latter Interest Payment Date**"); provided that the final interest period for the Notes will be the period from and including the Interest Payment Date immediately preceding the Stated Maturity of the Notes to, but excluding, the Stated Maturity. Interest on the Notes will be computed on the basis of the actual number of days elapsed in an Interest Period over a 360-day year.

The interest rate for the initial Interest Period will be Compounded SOFR determined on February 12, 2026, plus 0.53%. Thereafter, the interest rate for any Interest Period will be Compounded SOFR, as determined on the applicable date that is the second U.S. Government Securities Business Day (as defined herein) preceding such Interest Payment Date (the "**Interest Determination Date**"), plus a margin of 0.53%.

The amount of interest accrued and payable on the Notes for each Interest Period will be equal to the product of (i) the outstanding principal amount of the Notes multiplied by (ii) the product of (a) the Interest Rate for the relevant Interest Period multiplied by (b) the quotient of the actual number of calendar days in such Interest Period divided by 360.

As used herein the following terms have the meanings assigned to them:

"**Compounded SOFR**" means, with respect to any Interest Period, the rate computed in accordance with the following formula set forth below and the resulting percentage will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point (*e.g.*, 9.753973% (or .09753973) being rounded down to 9.75397% (or .0975397) and 9.753978% (or .09753978) being rounded up to 9.75398% (or .0975398)):

![](tm2529234d4_ex4-2img001.jpg)

where:

"**SOFR IndexStart**" is the SOFR Index value for the day that is two U.S. Government Securities Business Days preceding the first date of the relevant Interest Period;

"**SOFR IndexEnd**" is the SOFR Index value for the day that is two U.S. Government Securities Business Days preceding the Latter Interest Payment Date relating to such Interest Period; and

"**dc**" is the actual number of calendar days from (and including) SOFR IndexStart to (but excluding) SOFR IndexEnd (the actual number of calendar days in the applicable Observation Period).

For purposes of determining Compounded SOFR, "**SOFR Index**" means, with respect to any U.S. Government Securities Business Day:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) the SOFR Index value as published by the New York Federal Reserve as such index appears on the New York Federal Reserve's Website at 3:00 p.m. (New York time) on such U.S. Government Securities Business Day (the "**SOFR Determination Time**"); provided that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) if a SOFR Index value does not so appear as specified in clause (1) above at the SOFR Determination Time, then:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) if a Benchmark Transition Event and its related Benchmark Replacement Date (each as defined herein) have not occurred with respect to SOFR, then Compounded SOFR shall be the rate determined pursuant to the "SOFR Index Unavailable" provisions described below;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to SOFR, then Compounded SOFR shall be the rate determined pursuant to the "Effect of a Benchmark Transition Event" provisions described below.

"**New York Federal Reserve**" means the Federal Reserve Bank of New York (or a successor administrator of the Secured Overnight Financing Rate).

"**New York Federal Reserve's Website**" means the website of the New York Federal Reserve, currently at http://www.newyorkfed.org, or any successor source.

"**Observation Period**" means, in respect of each Interest Period, the period from and including two U.S. Government Securities Business Days preceding the first date of such relevant Interest Period to but excluding two U.S. Government Securities Business Days preceding the Latter Interest Payment Date for such Interest Period; provided that the first Observation Period shall be the period from and including two U.S. Government Securities Business Days preceding the settlement date of the Notes to, but excluding, the two U.S. Government Securities Business Days preceding the first Interest Payment Date.

"**Secured Overnight Financing Rate**" means the daily secured overnight financing rate as provided by the New York Federal Reserve on the New York Federal Reserve's Website.

"**U.S. Government Securities Business Day**" means any day except for a Saturday, Sunday or a day on which the Securities Industry and Financial Markets Association recommends that the fixed income departments of its members be closed for the entire day for purposes of trading in U.S. government securities.

**SOFR Index Unavailable**

If a SOFR IndexStart or SOFR IndexEnd is not published on the associated Interest Determination Date and a Benchmark Transition Event and its related Benchmark Replacement Date have not occurred with respect to the Secured Overnight Financing Rate, "Compounded SOFR" means, for the applicable Interest Period for which such index is not available, the rate of return on a daily compounded interest investment calculated in accordance with the formula for SOFR Averages, and definitions required for such formula, published on the New York Federal Reserve's Website at https://www.newyorkfed.org/markets/treasury-repo-reference-rates-information. For the purposes of this provision, references in the SOFR Averages compounding formula and related definitions to "calculation period" shall be replaced with "Observation Period" and the words "that is, 30-, 90-, or 180- calendar days" shall be removed. If the daily Secured Overnight Financing Rate ("**SOFRi**") does not so appear for any day, "i" in the Observation Period, SOFRi for such day "i" shall be SOFR published in respect of the first preceding U.S. Government Securities Business Day for which the Secured Overnight Financing Rate was published on the New York Federal Reserve's Website.

**Effect of a Benchmark Transition Event**

If the Company or its designee determine on or prior to the relevant Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to the then-current Benchmark, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Notes in respect of all determinations on such date and for all determinations on all subsequent dates.

In connection with the implementation of a Benchmark Replacement, the Company or its designee will have the right to make Benchmark Replacement Conforming Changes from time to time.

Any determination, decision or election that may be made by the Company or its designee pursuant to this section, including a determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) will be conclusive and binding absent manifest error;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) will be made in the Company or its designee's sole discretion; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) notwithstanding anything to the contrary in the documentation relating to the Notes, shall become effective without consent from the holders of the Notes or any other party.

Any determination, decision or election pursuant to the benchmark replacement provisions shall be made by the Company or its designee (which may be the Company's affiliate) on the basis as described above, and in no event shall the Calculation Agent, Trustee or Paying Agent be responsible for making any such determination, decision or election.

As used herein the following terms have the meanings assigned to them:

"**Benchmark**" means, initially, Compounded SOFR, as such term is defined above; provided that if the Company or its designee determine on or prior to the Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Compounded SOFR (or the published daily SOFR Index used in the calculation thereof) or the then-current Benchmark, then "Benchmark" means the applicable Benchmark Replacement.

"**Benchmark Replacement**" means the first alternative set forth in the order below that can be determined by the Company or its designee as of the Benchmark Replacement Date:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) the sum of (a) the alternate rate of interest that has been selected or recommended by the Relevant Governmental Body as the replacement for the then-current Benchmark and (b) the Benchmark Replacement Adjustment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) the sum of (a) the ISDA Fallback Rate and (b) the Benchmark Replacement Adjustment; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) the sum of (a) the alternate rate of interest that has been selected by the Company or its designee as the replacement for the then-current Benchmark giving due consideration to any industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar-denominated floating rate notes at such time and (b) the Benchmark Replacement Adjustment.

"**Benchmark Replacement Adjustment**" means the first alternative set forth in the order below that can be determined by the Company or its designee as of the Benchmark Replacement Date:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) the spread adjustment, or method for calculating or determining such spread adjustment (which may be a positive or negative value or zero), that has been selected or recommended by the Relevant Governmental Body for the applicable Unadjusted Benchmark Replacement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) if the applicable Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, the ISDA Fallback Adjustment; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) the spread adjustment (which may be a positive or negative value or zero) that has been selected by the Company or its designee giving due consideration to any industry-accepted spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of the then-current Benchmark with the applicable Unadjusted Benchmark Replacement for U.S. dollar-denominated floating rate notes at such time.

"**Benchmark Replacement Conforming Changes**" means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definition of the Interest Period, timing and frequency of determining rates and making payments of interest, rounding of amounts or tenors and other administrative matters) that the Company or its designee decide may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Company or its designee decide that adoption of any portion of such market practice is not administratively feasible or if the Company or its designee determine that no market practice for use of the Benchmark Replacement exists, in such other manner as the Company or its designee determine is reasonably necessary).

"**Benchmark Replacement Date**" means the earliest to occur of the following events with respect to the then-current Benchmark (including the daily published component used in the calculation thereof):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) in the case of clause (1) or (2) of the definition of "Benchmark Transition Event," the later of (a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of the Benchmark permanently or indefinitely ceases to provide the Benchmark (or such component); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) in the case of clause (3) of the definition of "Benchmark Transition Event," the date of the public statement or publication of information referenced therein.

For the avoidance of doubt, if the event that gives rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination.

For the avoidance of doubt, for purposes of the definitions of Benchmark Replacement Date and Benchmark Transition Event, references to Benchmark also include any reference rate underlying such Benchmark.

AMPHENOL CORPORATION

3.900% SENIOR NOTES DUE 2028

This Global Note designated on the face hereof as 3.900% Senior Notes due 2028 (the "**Notes**") is a duly authorized issue of securities of the Company issued and issuable in one or more series under an indenture, dated as of March 16, 2023 (the "**Base Indenture**"), between the Company and U.S. Bank Trust Company, National Association, as trustee (the "**Trustee**," which term includes any successor trustee under such indenture), to such indenture, as supplemented by an Officers' Certificate dated as of November 10, 2025 establishing the terms of the Notes (the "**Officers' Certificate**," and together with the Base Indenture, the "**Indenture**"), 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. Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Indenture.

The Notes are not subject to a mandatory or optional sinking fund requirement.

The Notes shall be redeemable, at the Company's option, in whole or in part, at any time or from time to time, at the redemption prices described in the Indenture.

The Notes will be subject to a special mandatory redemption (at a price equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest from the date of initial issuance, or the most recent date to which interest has been paid or provided for, whichever is later, to, but not including, the special mandatory redemption date) under certain circumstances described in the Indenture.

If a Change of Control Repurchase Event occurs, unless the Company has exercised its right to redeem all of the Notes as described above, each Holder of the Notes shall have the right to require the Company to repurchase all or any part (equal to $2,000 and integral multiples of $1,000 in excess thereof) of such Holder's Notes pursuant to the offer described in the Indenture, at a purchase price in cash equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase (subject to the right of Holders of record on the relevant Interest Record Date to receive interest due on the relevant Interest Payment Date).

If an Event of Default (as defined in the Indenture) with respect to the Notes of this Series occurs and is continuing, the principal of the Notes of this Series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each Series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time outstanding of each Series to be affected. Without the consent of any Holder of Securities, the Indenture or the Securities may be amended to cure, correct or supplement any ambiguity, omission, defect or inconsistency as to the Securities of such Series or to make any change that does not adversely affect the rights of any Holder of the Securities of such Series in any material respect. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each Series at the time outstanding, on behalf of the Holders of all Securities of such Series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Until such waiver becomes effective, a consent to it by a Holder of this Note is a continuing consent by the Holder and every subsequent Holder of this Note or portion of this Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on this Note. However, any such Holder or subsequent Holder may revoke the consent as to such Holder's Note or portion of this Note if the Trustee receives the notice of revocation before the date of the waiver becomes effective. Any amendment or waiver once effective shall bind every Holder of each Series affected by such amendment or waiver, subject to certain exceptions provided for in the Indenture.

Every amendment to the Indenture or the Securities of one or more Series shall be set forth in a Supplemental Indenture that complies with the TIA as then in effect.

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 interest on this Note at the times and place and at the rate and in the currency herein prescribed.

A Holder shall register the transfer of or exchange Notes in accordance with the Indenture. The Company may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. Neither the Company nor the Registrar shall be required (a) to issue, register the transfer of, or exchange Notes of any Series for the period beginning at the opening of business fifteen days immediately preceding the mailing of a notice of redemption of Notes of such Series selected for redemption and ending at the close of business on the day of such mailing, or (b) to register the transfer of or exchange Notes of any Series selected, called or being called for redemption as a whole or the portion being redeemed of any such Securities selected, called or being called for redemption in part.

The Company may be discharged from its obligations under the Notes and under the Indenture with respect to the Notes except for certain provisions thereof, and may be discharged from obligations to comply with certain covenants contained in the Notes and in the Indenture with respect to the Notes, in each case upon satisfaction of certain conditions specified in the Indenture.

A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under this Note or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting the Note waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Note.

The registered Holder of this Note shall be treated as the owner of it for all purposes.

If funds for the payment of principal or interest remain unclaimed for two years, the Trustee and the Paying Agent will repay the funds to the Company at its written request. After that, all liability of the Trustee and such Paying Agent with respect to such funds shall cease.

The Trustee shall act as the Registrar, Paying Agent and Service Agent (as defined in the Indenture) for the Notes. The Notes shall be issued in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The Notes shall be issued only in registered form without coupons. In the event of a declaration of acceleration of the maturity of the Notes pursuant to the Indenture, 100% of the principal amount of the Notes shall be payable. The Notes shall be issued in United States dollars and principal of and premium, if any, and interest on the Notes shall be paid in United States dollars. The Notes shall be unsecured debt securities of the Company. The Notes shall not be convertible to any other securities of the Company. The Indenture and this Note shall be governed by and construed in accordance with the laws of the State of New York.

In order to comply with applicable tax laws (inclusive of rules, regulations and interpretations promulgated by competent authorities) related to the Notes in effect from time to time ("**Applicable Law**") that a foreign financial institution, issuer, trustee, paying agent or other party is or has agreed to be subject to, the Company agrees (i) upon written request of the Trustee, to provide to the Trustee, to the extent reasonably available to the Company, sufficient information about the parties and/or transactions (including any modification to the terms of such transactions) so the Trustee can determine whether it has tax related obligations under Applicable Law and (ii) that the Trustee shall be entitled to make any withholding or deduction from payments to the extent necessary to comply with Applicable Law for which the Trustee shall not have any liability.

AMPHENOL CORPORATION

4.400% SENIOR NOTES DUE 2033

This Global Note designated on the face hereof as 4.400% Senior Notes due 2033 (the "**Notes**") is a duly authorized issue of securities of the Company issued and issuable in one or more series under an indenture, dated as of March 16, 2023 (the "**Base Indenture**"), between the Company and U.S. Bank Trust Company, National Association, as trustee (the "**Trustee**," which term includes any successor trustee under such indenture), to such indenture, as supplemented by an Officers' Certificate dated as of November 10, 2025 establishing the terms of the Notes (the "**Officers' Certificate**," and together with the Base Indenture, the "**Indenture**"), 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. Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Indenture.

The Notes are not subject to a mandatory or optional sinking fund requirement.

The Notes shall be redeemable, at the Company's option, in whole or in part, at any time or from time to time, at the redemption prices described in the Indenture.

The Notes will be subject to a special mandatory redemption (at a price equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest from the date of initial issuance, or the most recent date to which interest has been paid or provided for, whichever is later, to, but not including, the special mandatory redemption date) under certain circumstances described in the Indenture.

If a Change of Control Repurchase Event occurs, unless the Company has exercised its right to redeem all of the Notes as described above, each Holder of the Notes shall have the right to require the Company to repurchase all or any part (equal to $2,000 and integral multiples of $1,000 in excess thereof) of such Holder's Notes pursuant to the offer described in the Indenture, at a purchase price in cash equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase (subject to the right of Holders of record on the relevant Interest Record Date to receive interest due on the relevant Interest Payment Date).

If an Event of Default (as defined in the Indenture) with respect to the Notes of this Series occurs and is continuing, the principal of the Notes of this Series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each Series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time outstanding of each Series to be affected. Without the consent of any Holder of Securities, the Indenture or the Securities may be amended to cure, correct or supplement any ambiguity, omission, defect or inconsistency as to the Securities of such Series or to make any change that does not adversely affect the rights of any Holder of the Securities of such Series in any material respect. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each Series at the time outstanding, on behalf of the Holders of all Securities of such Series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Until such waiver becomes effective, a consent to it by a Holder of this Note is a continuing consent by the Holder and every subsequent Holder of this Note or portion of this Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on this Note. However, any such Holder or subsequent Holder may revoke the consent as to such Holder's Note or portion of this Note if the Trustee receives the notice of revocation before the date of the waiver becomes effective. Any amendment or waiver once effective shall bind every Holder of each Series affected by such amendment or waiver, subject to certain exceptions provided for in the Indenture.

Every amendment to the Indenture or the Securities of one or more Series shall be set forth in a Supplemental Indenture that complies with the TIA as then in effect.

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 interest on this Note at the times and place and at the rate and in the currency herein prescribed.

A Holder shall register the transfer of or exchange Notes in accordance with the Indenture. The Company may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. Neither the Company nor the Registrar shall be required (a) to issue, register the transfer of, or exchange Notes of any Series for the period beginning at the opening of business fifteen days immediately preceding the mailing of a notice of redemption of Notes of such Series selected for redemption and ending at the close of business on the day of such mailing, or (b) to register the transfer of or exchange Notes of any Series selected, called or being called for redemption as a whole or the portion being redeemed of any such Securities selected, called or being called for redemption in part.

The Company may be discharged from its obligations under the Notes and under the Indenture with respect to the Notes except for certain provisions thereof, and may be discharged from obligations to comply with certain covenants contained in the Notes and in the Indenture with respect to the Notes, in each case upon satisfaction of certain conditions specified in the Indenture.

A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under this Note or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting the Note waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Note.

The registered Holder of this Note shall be treated as the owner of it for all purposes.

If funds for the payment of principal or interest remain unclaimed for two years, the Trustee and the Paying Agent will repay the funds to the Company at its written request. After that, all liability of the Trustee and such Paying Agent with respect to such funds shall cease.

The Trustee shall act as the Registrar, Paying Agent and Service Agent (as defined in the Indenture) for the Notes. The Notes shall be issued in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The Notes shall be issued only in registered form without coupons. In the event of a declaration of acceleration of the maturity of the Notes pursuant to the Indenture, 100% of the principal amount of the Notes shall be payable. The Notes shall be issued in United States dollars and principal of and premium, if any, and interest on the Notes shall be paid in United States dollars. The Notes shall be unsecured debt securities of the Company. The Notes shall not be convertible to any other securities of the Company. The Indenture and this Note shall be governed by and construed in accordance with the laws of the State of New York.

In order to comply with applicable tax laws (inclusive of rules, regulations and interpretations promulgated by competent authorities) related to the Notes in effect from time to time ("**Applicable Law**") that a foreign financial institution, issuer, trustee, paying agent or other party is or has agreed to be subject to, the Company agrees (i) upon written request of the Trustee, to provide to the Trustee, to the extent reasonably available to the Company, sufficient information about the parties and/or transactions (including any modification to the terms of such transactions) so the Trustee can determine whether it has tax related obligations under Applicable Law and (ii) that the Trustee shall be entitled to make any withholding or deduction from payments to the extent necessary to comply with Applicable Law for which the Trustee shall not have any liability.

AMPHENOL CORPORATION

5.300% SENIOR NOTES DUE 2055

This Global Note designated on the face hereof as 5.300% Senior Notes due 2055 (the "**Notes**") is a duly authorized issue of securities of the Company issued and issuable in one or more series under an indenture, dated as of March 16, 2023 (the "**Base Indenture**"), between the Company and U.S. Bank Trust Company, National Association, as trustee (the "**Trustee**," which term includes any successor trustee under such indenture), to such indenture, as supplemented by an Officers' Certificate dated as of November 10, 2025 establishing the terms of the Notes (the "**Officers' Certificate**," and together with the Base Indenture, the "**Indenture**"), 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. Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Indenture.

The Notes are not subject to a mandatory or optional sinking fund requirement.

The Notes shall be redeemable, at the Company's option, in whole or in part, at any time or from time to time, at the redemption prices described in the Indenture.

The Notes will be subject to a special mandatory redemption (at a price equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest from the date of initial issuance, or the most recent date to which interest has been paid or provided for, whichever is later, to, but not including, the special mandatory redemption date) under certain circumstances described in the Indenture.

If a Change of Control Repurchase Event occurs, unless the Company has exercised its right to redeem all of the Notes as described above, each Holder of the Notes shall have the right to require the Company to repurchase all or any part (equal to $2,000 and integral multiples of $1,000 in excess thereof) of such Holder's Notes pursuant to the offer described in the Indenture, at a purchase price in cash equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase (subject to the right of Holders of record on the relevant Interest Record Date to receive interest due on the relevant Interest Payment Date).

If an Event of Default (as defined in the Indenture) with respect to the Notes of this Series occurs and is continuing, the principal of the Notes of this Series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each Series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time outstanding of each Series to be affected. Without the consent of any Holder of Securities, the Indenture or the Securities may be amended to cure, correct or supplement any ambiguity, omission, defect or inconsistency as to the Securities of such Series or to make any change that does not adversely affect the rights of any Holder of the Securities of such Series in any material respect. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each Series at the time outstanding, on behalf of the Holders of all Securities of such Series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Until such waiver becomes effective, a consent to it by a Holder of this Note is a continuing consent by the Holder and every subsequent Holder of this Note or portion of this Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on this Note. However, any such Holder or subsequent Holder may revoke the consent as to such Holder's Note or portion of this Note if the Trustee receives the notice of revocation before the date of the waiver becomes effective. Any amendment or waiver once effective shall bind every Holder of each Series affected by such amendment or waiver, subject to certain exceptions provided for in the Indenture.

Every amendment to the Indenture or the Securities of one or more Series shall be set forth in a Supplemental Indenture that complies with the TIA as then in effect.

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 interest on this Note at the times and place and at the rate and in the currency herein prescribed.

A Holder shall register the transfer of or exchange Notes in accordance with the Indenture. The Company may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. Neither the Company nor the Registrar shall be required (a) to issue, register the transfer of, or exchange Notes of any Series for the period beginning at the opening of business fifteen days immediately preceding the mailing of a notice of redemption of Notes of such Series selected for redemption and ending at the close of business on the day of such mailing, or (b) to register the transfer of or exchange Notes of any Series selected, called or being called for redemption as a whole or the portion being redeemed of any such Securities selected, called or being called for redemption in part.

The Company may be discharged from its obligations under the Notes and under the Indenture with respect to the Notes except for certain provisions thereof, and may be discharged from obligations to comply with certain covenants contained in the Notes and in the Indenture with respect to the Notes, in each case upon satisfaction of certain conditions specified in the Indenture.

A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under this Note or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting the Note waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Note.

The registered Holder of this Note shall be treated as the owner of it for all purposes.

If funds for the payment of principal or interest remain unclaimed for two years, the Trustee and the Paying Agent will repay the funds to the Company at its written request. After that, all liability of the Trustee and such Paying Agent with respect to such funds shall cease.

The Trustee shall act as the Registrar, Paying Agent and Service Agent (as defined in the Indenture) for the Notes. The Notes shall be issued in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The Notes shall be issued only in registered form without coupons. In the event of a declaration of acceleration of the maturity of the Notes pursuant to the Indenture, 100% of the principal amount of the Notes shall be payable. The Notes shall be issued in United States dollars and principal of and premium, if any, and interest on the Notes shall be paid in United States dollars. The Notes shall be unsecured debt securities of the Company. The Notes shall not be convertible to any other securities of the Company. The Indenture and this Note shall be governed by and construed in accordance with the laws of the State of New York.

In order to comply with applicable tax laws (inclusive of rules, regulations and interpretations promulgated by competent authorities) related to the Notes in effect from time to time ("**Applicable Law**") that a foreign financial institution, issuer, trustee, paying agent or other party is or has agreed to be subject to, the Company agrees (i) upon written request of the Trustee, to provide to the Trustee, to the extent reasonably available to the Company, sufficient information about the parties and/or transactions (including any modification to the terms of such transactions) so the Trustee can determine whether it has tax related obligations under Applicable Law and (ii) that the Trustee shall be entitled to make any withholding or deduction from payments to the extent necessary to comply with Applicable Law for which the Trustee shall not have any liability.

(REVERSE OF NOTE)

AMPHENOL CORPORATION

FLOATING RATE NOTES DUE 2027

This Global Note designated on the face hereof as Floating Rate Notes due 2027 (the "**Notes**") is a duly authorized issue of securities of the Company issued and issuable in one or more series under an indenture, dated as of March 16, 2023 (the "**Base Indenture**"), between the Company and U.S. Bank Trust Company, National Association, as trustee (the "**Trustee**," which term includes any successor trustee under such indenture), to such indenture, as supplemented by an Officers' Certificate dated as of November 10, 2025 establishing the terms of the Notes (the "**Officers' Certificate**," and together with the Base Indenture, the "**Indenture**"), 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. Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Indenture.

The Notes will bear interest at a floating rate per annum, reset quarterly on each Interest Payment Date (as defined herein), equal to Compounded SOFR, plus 0.53%. In no event will the interest on the Notes be less than zero. Interest on the Notes will be payable quarterly in arrears on February 15, May 15, August 15 and November 15 of each year, commencing on February 15, 2026, and at maturity (each such date, an "**Interest Payment Date**"), to Holders of record on the date that is 15 calendar days prior to each Interest Payment Date (the "**Interest Record Dates**"), whether or not a Business Day. Interest on the Notes will accrue from and including the most recent Interest Payment Date or, if no interest has been paid, from the settlement date of the Notes. If the February 15, May 15, August 15 or November 15 of any year is not a Business Day, then the next succeeding Business Day will be the applicable Interest Payment Date and interest on the Notes will be paid on such next succeeding Business Day (unless such next succeeding Business Day falls in the succeeding calendar month, in which case the applicable Interest Payment Date will be the Business Day immediately preceding such February 15, May 15, August 15 or November 15, and interest on the Notes will be paid on such immediately preceding Business Day). If the Stated Maturity of the Notes is not a Business Day, the payment of principal of, and interest on, the Notes will be made on the next succeeding Business Day, and no interest will accrue for the period from and after the Stated Maturity.

The "**initial Interest Period**" means the period from and including the settlement date of the Notes to, but excluding, the first Interest Payment Date. Thereafter, each "**Interest Period**" means the period from and including a Interest Payment Date to, but excluding, the immediately succeeding Interest Payment Date (such succeeding Interest Payment Date, the "**Latter Interest Payment Date**"); provided that the final interest period for the Notes will be the period from and including the Interest Payment Date immediately preceding the Stated Maturity of the Notes to, but excluding, the Stated Maturity. Interest on the Notes will be computed on the basis of the actual number of days elapsed in an Interest Period over a 360-day year.

The interest rate for the initial Interest Period will be Compounded SOFR determined on February 12, 2026, plus 0.53%. Thereafter, the interest rate for any Interest Period will be Compounded SOFR, as determined on the applicable date that is the second U.S. Government Securities Business Day (as defined herein) preceding such Interest Payment Date (the "**Interest Determination Date**"), plus a margin of 0.53%.

The amount of interest accrued and payable on the Notes for each Interest Period will be equal to the product of (i) the outstanding principal amount of the Notes multiplied by (ii) the product of (a) the Interest Rate for the relevant Interest Period multiplied by (b) the quotient of the actual number of calendar days in such Interest Period divided by 360.

As used herein the following terms have the meanings assigned to them:

"**Compounded SOFR**" means, with respect to any Interest Period, the rate computed in accordance with the following formula set forth below and the resulting percentage will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point (*e.g.*, 9.753973% (or .09753973) being rounded down to 9.75397% (or .0975397) and 9.753978% (or .09753978) being rounded up to 9.75398% (or .0975398)):

![A black text on a white background AI-generated content may be incorrect.](tm2529234d4_ex4-3img001.jpg)

where:

"**SOFR IndexStart**" is the SOFR Index value for the day that is two U.S. Government Securities Business Days preceding the first date of the relevant Interest Period;

"**SOFR IndexEnd**" is the SOFR Index value for the day that is two U.S. Government Securities Business Days preceding the Latter Interest Payment Date relating to such Interest Period; and

"**dc**" is the actual number of calendar days from (and including) SOFR IndexStart to (but excluding) SOFR IndexEnd (the actual number of calendar days in the applicable Observation Period).

For purposes of determining Compounded SOFR, "**SOFR Index**" means, with respect to any U.S. Government Securities Business Day:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) the SOFR Index value as published by the New York Federal Reserve as such index appears on the New York Federal Reserve's Website at 3:00 p.m. (New York time) on such U.S. Government Securities Business Day (the "**SOFR Determination Time**"); provided that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) if a SOFR Index value does not so appear as specified in clause (1) above at the SOFR Determination Time, then:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) if a Benchmark Transition Event and its related Benchmark Replacement Date (each as defined herein) have not occurred with respect to SOFR, then Compounded SOFR shall be the rate determined pursuant to the "SOFR Index Unavailable" provisions described below;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to SOFR, then Compounded SOFR shall be the rate determined pursuant to the "Effect of a Benchmark Transition Event" provisions described below.

"**New York Federal Reserve**" means the Federal Reserve Bank of New York (or a successor administrator of the Secured Overnight Financing Rate).

"**New York Federal Reserve's Website**" means the website of the New York Federal Reserve, currently at http://www.newyorkfed.org, or any successor source.

"**Observation Period**" means, in respect of each Interest Period, the period from and including two U.S. Government Securities Business Days preceding the first date of such relevant Interest Period to but excluding two U.S. Government Securities Business Days preceding the Latter Interest Payment Date for such Interest Period; provided that the first Observation Period shall be the period from and including two U.S. Government Securities Business Days preceding the settlement date of the Notes to, but excluding, the two U.S. Government Securities Business Days preceding the first Interest Payment Date.

"**Secured Overnight Financing Rate**" means the daily secured overnight financing rate as provided by the New York Federal Reserve on the New York Federal Reserve's Website.

"**U.S. Government Securities Business Day**" means any day except for a Saturday, Sunday or a day on which the Securities Industry and Financial Markets Association recommends that the fixed income departments of its members be closed for the entire day for purposes of trading in U.S. government securities.

**SOFR Index Unavailable**

If a SOFR IndexStart or SOFR IndexEnd is not published on the associated Interest Determination Date and a Benchmark Transition Event and its related Benchmark Replacement Date have not occurred with respect to the Secured Overnight Financing Rate, "Compounded SOFR" means, for the applicable Interest Period for which such index is not available, the rate of return on a daily compounded interest investment calculated in accordance with the formula for SOFR Averages, and definitions required for such formula, published on the New York Federal Reserve's Website at https://www.newyorkfed.org/markets/treasury-repo-reference-rates-information. For the purposes of this provision, references in the SOFR Averages compounding formula and related definitions to "calculation period" shall be replaced with "Observation Period" and the words "that is, 30-, 90-, or 180- calendar days" shall be removed. If the daily Secured Overnight Financing Rate ("**SOFRi**") does not so appear for any day, "i" in the Observation Period, SOFRi for such day "i" shall be SOFR published in respect of the first preceding U.S. Government Securities Business Day for which the Secured Overnight Financing Rate was published on the New York Federal Reserve's Website.

**Effect of a Benchmark Transition Event**

If the Company or its designee determine on or prior to the relevant Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to the then-current Benchmark, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Notes in respect of all determinations on such date and for all determinations on all subsequent dates.

In connection with the implementation of a Benchmark Replacement, the Company or its designee will have the right to make Benchmark Replacement Conforming Changes from time to time.

Any determination, decision or election that may be made by the Company or its designee pursuant to this section, including a determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) will be conclusive and binding absent manifest error;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) will be made in the Company or its designee's sole discretion; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) notwithstanding anything to the contrary in the documentation relating to the Notes, shall become effective without consent from the holders of the Notes or any other party.

Any determination, decision or election pursuant to the benchmark replacement provisions shall be made by the Company or its designee (which may be the Company's affiliate) on the basis as described above, and in no event shall the Calculation Agent, Trustee or Paying Agent be responsible for making any such determination, decision or election.

As used herein the following terms have the meanings assigned to them:

"**Benchmark**" means, initially, Compounded SOFR, as such term is defined above; provided that if the Company or its designee determine on or prior to the Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Compounded SOFR (or the published daily SOFR Index used in the calculation thereof) or the then-current Benchmark, then "Benchmark" means the applicable Benchmark Replacement.

"**Benchmark Replacement**" means the first alternative set forth in the order below that can be determined by the Company or its designee as of the Benchmark Replacement Date:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) the sum of (a) the alternate rate of interest that has been selected or recommended by the Relevant Governmental Body as the replacement for the then-current Benchmark and (b) the Benchmark Replacement Adjustment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) the sum of (a) the ISDA Fallback Rate and (b) the Benchmark Replacement Adjustment; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) the sum of (a) the alternate rate of interest that has been selected by the Company or its designee as the replacement for the then-current Benchmark giving due consideration to any industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar-denominated floating rate notes at such time and (b) the Benchmark Replacement Adjustment.

"**Benchmark Replacement Adjustment**" means the first alternative set forth in the order below that can be determined by the Company or its designee as of the Benchmark Replacement Date:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) the spread adjustment, or method for calculating or determining such spread adjustment (which may be a positive or negative value or zero), that has been selected or recommended by the Relevant Governmental Body for the applicable Unadjusted Benchmark Replacement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) if the applicable Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, the ISDA Fallback Adjustment; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) the spread adjustment (which may be a positive or negative value or zero) that has been selected by the Company or its designee giving due consideration to any industry-accepted spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of the then-current Benchmark with the applicable Unadjusted Benchmark Replacement for U.S. dollar-denominated floating rate notes at such time.

"**Benchmark Replacement Conforming Changes**" means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definition of the Interest Period, timing and frequency of determining rates and making payments of interest, rounding of amounts or tenors and other administrative matters) that the Company or its designee decide may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Company or its designee decide that adoption of any portion of such market practice is not administratively feasible or if the Company or its designee determine that no market practice for use of the Benchmark Replacement exists, in such other manner as the Company or its designee determine is reasonably necessary).

"**Benchmark Replacement Date**" means the earliest to occur of the following events with respect to the then-current Benchmark (including the daily published component used in the calculation thereof):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) in the case of clause (1) or (2) of the definition of "Benchmark Transition Event," the later of (a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of the Benchmark permanently or indefinitely ceases to provide the Benchmark (or such component); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) in the case of clause (3) of the definition of "Benchmark Transition Event," the date of the public statement or publication of information referenced therein.

For the avoidance of doubt, if the event that gives rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination.

For the avoidance of doubt, for purposes of the definitions of Benchmark Replacement Date and Benchmark Transition Event, references to Benchmark also include any reference rate underlying such Benchmark.

"**Benchmark Transition Event**" means the occurrence of one or more of the following events with respect to the then-current Benchmark (including the daily published component used in the calculation thereof):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) a public statement or publication of information by or on behalf of the administrator of the Benchmark (or such component) announcing that such administrator has ceased or will cease to provide the Benchmark (or such component), permanently or indefinitely; *provided* that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark (or such component);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark (or such component), the central bank for the currency of the Benchmark (or such component), an insolvency official with jurisdiction over the administrator for the Benchmark (or such component), a resolution authority with jurisdiction over the administrator for the Benchmark (or such component) or a court or an entity with similar insolvency or resolution authority over the administrator for the Benchmark, which states that the administrator of the Benchmark (or such component) has ceased or will cease to provide the Benchmark (or such component) permanently or indefinitely; *provided* that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark (or such component); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark announcing that the Benchmark is no longer representative.

"**ISDA Definitions**" means the 2006 ISDA Definitions published by the International Swaps and Derivatives Association, Inc. or any successor thereto, as amended or supplemented from time to time, or any successor definitional booklet for interest rate derivatives published from time to time.

"**ISDA Fallback Adjustment**" means the spread adjustment (which may be a positive or negative value or zero) that would apply for derivatives transactions referencing the ISDA Definitions to be determined upon the occurrence of an index cessation event with respect to the Benchmark.

"**ISDA Fallback Rate**" means the rate that would apply for derivatives transactions referencing the ISDA Definitions to be effective upon the occurrence of an index cessation date with respect to the Benchmark for the applicable tenor excluding the applicable ISDA Fallback Adjustment.

"**Reference Time**" with respect to any determination of the Benchmark means (1) if the Benchmark is Compounded SOFR, the SOFR Determination Time, and (2) if the Benchmark is not Compounded SOFR, the time determined by the Company or its designee after giving effect to the Benchmark Replacement Conforming Changes.

"**Relevant Governmental Body**" means the Federal Reserve Board and/or the Federal Reserve Bank of New York, or a committee officially endorsed or convened by the Federal Reserve Board and/or the Federal Reserve Bank of New York or any successor thereto.

"**Unadjusted Benchmark Replacement**" means the Benchmark Replacement excluding the Benchmark Replacement Adjustment.

The interest rate and amount of interest to be paid on the Notes for each interest period will be determined by the Calculation Agent. Initially, U.S. Bank Trust Company, National Association will be serving as the Company's Calculation Agent; however, the Company may change the Calculation Agent at any time without notice, and U.S. Bank Trust Company, National Association may resign as Calculation Agent at any time with prior written notice to the Company. In the event that any then-acting Calculation Agent shall be unable or unwilling to act or that the Company proposes to remove such Calculation Agent, the Company will appoint another Calculation Agent. If the Company fails to appoint a Calculation Agent, the Company will serve as Calculation Agent.

The Calculation Agent will, upon the request of any Holder of the Notes, provide the interest rate then in effect with respect to the Notes. All calculations made by the Calculation Agent shall, in the absence of manifest error, be conclusive for all purposes and binding on the Company, the Holders of the Notes, the Trustee and the Paying Agent. None of the Trustee or the Paying Agent shall have any responsibility to determine whether any manifest error has occurred and, in the absence of notice from the Company, may conclusively assume that no manifest error exists and shall suffer no liability in so assuming.

None of the Trustee, the Paying Agent or the Calculation Agent shall be under any obligation to (1) monitor, determine or verify the unavailability or cessation of SOFR, SOFRi or the SOFR Index, or whether or when there has occurred, or to give notice to any Holder or other transaction party of the occurrence of, any Benchmark Transition Event or related Benchmark Replacement Date, (2) to select, determine or designate any Benchmark Replacement, or other successor or replacement benchmark index, or whether any conditions to the designation of such a rate or index have been satisfied, (3) to select, determine or designate any Benchmark Replacement Adjustment, or other modifier to any replacement or successor index or (4) to determine whether or what Benchmark Replacement Conforming Changes are necessary or advisable, if any, in connection with any of the foregoing, including, but not limited to, adjustments as to any alternative spread thereon, the business day convention, Interest Determination Dates or any other relevant methodology applicable to such substitute or successor benchmark.

In connection with the foregoing, each of the Trustee, the Paying Agent and the Calculation Agent shall be entitled to conclusively rely on any determinations made by the Company or its designee without independent investigation, and none will have any liability for actions taken at the Company's direction in connection therewith.

None of the Trustee, the Paying Agent or the Calculation Agent shall be liable for any inability, failure or delay on its part to perform any of its duties set forth in the Indenture as a result of the unavailability of SOFR, SOFRi, the SOFR Index or other applicable Benchmark Replacement, including as a result of any failure, inability, delay, error or inaccuracy on the part of any other transaction party in providing any direction, instruction, notice or information required or contemplated by the terms of the Indenture and reasonably required for the performance of such duties. None of the Trustee, the Paying Agent or the Calculation Agent shall be responsible or liable for the Company's actions or omissions or for those of the Company's designee, or for any failure or delay in the performance by the Company or its designee, nor shall any of the Trustee, the Paying Agent or the Calculation Agent be under any obligation to oversee or monitor the performance of the Company or its designee.

The Notes are not subject to a mandatory or optional sinking fund requirement.

The Notes are not redeemable at the Company's option prior to the Stated Maturity.

The Notes will be subject to a special mandatory redemption (at a price equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest from the date of initial issuance, or the most recent date to which interest has been paid or provided for, whichever is later, to, but not including, the special mandatory redemption date) under certain circumstances described in the Indenture.

If a Change of Control Repurchase Event occurs, unless the Company has exercised its right to redeem all of the Notes as described above, each Holder of the Notes shall have the right to require the Company to repurchase all or any part (equal to $2,000 and integral multiples of $1,000 in excess thereof) of such Holder's Notes pursuant to the offer described in the Indenture, at a purchase price in cash equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase (subject to the right of Holders of record on the relevant Interest Record Date to receive interest due on the relevant Interest Payment Date).

If an Event of Default (as defined in the Indenture) with respect to the Notes of this Series occurs and is continuing, the principal of the Notes of this Series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each Series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time outstanding of each Series to be affected. Without the consent of any Holder of Securities, the Indenture or the Securities may be amended to cure, correct or supplement any ambiguity, omission, defect or inconsistency as to the Securities of such Series or to make any change that does not adversely affect the rights of any Holder of the Securities of such Series in any material respect. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each Series at the time outstanding, on behalf of the Holders of all Securities of such Series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Until such waiver becomes effective, a consent to it by a Holder of this Note is a continuing consent by the Holder and every subsequent Holder of this Note or portion of this Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on this Note. However, any such Holder or subsequent Holder may revoke the consent as to such Holder's Note or portion of this Note if the Trustee receives the notice of revocation before the date of the waiver becomes effective. Any amendment or waiver once effective shall bind every Holder of each Series affected by such amendment or waiver, subject to certain exceptions provided for in the Indenture.

Every amendment to the Indenture or the Securities of one or more Series shall be set forth in a Supplemental Indenture that complies with the TIA as then in effect.

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 interest on this Note at the times and place and at the rate and in the currency herein prescribed.

A Holder shall register the transfer of or exchange Notes in accordance with the Indenture. The Company may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. Neither the Company nor the Registrar shall be required (a) to issue, register the transfer of, or exchange Notes of any Series for the period beginning at the opening of business fifteen days immediately preceding the mailing of a notice of redemption of Notes of such Series selected for redemption and ending at the close of business on the day of such mailing, or (b) to register the transfer of or exchange Notes of any Series selected, called or being called for redemption as a whole or the portion being redeemed of any such Securities selected, called or being called for redemption in part.

The Company may be discharged from its obligations under the Notes and under the Indenture with respect to the Notes except for certain provisions thereof, and may be discharged from obligations to comply with certain covenants contained in the Notes and in the Indenture with respect to the Notes, in each case upon satisfaction of certain conditions specified in the Indenture.

A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under this Note or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting the Note waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Note.

The registered Holder of this Note shall be treated as the owner of it for all purposes.

If funds for the payment of principal or interest remain unclaimed for two years, the Trustee and the Paying Agent will repay the funds to the Company at its written request. After that, all liability of the Trustee and such Paying Agent with respect to such funds shall cease.

The Trustee shall act as the Registrar, Paying Agent and Service Agent (as defined in the Indenture) for the Notes. The Notes shall be issued in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The Notes shall be issued only in registered form without coupons. In the event of a declaration of acceleration of the maturity of the Notes pursuant to the Indenture, 100% of the principal amount of the Notes shall be payable. The Notes shall be issued in United States dollars and principal of and premium, if any, and interest on the Notes shall be paid in United States dollars. The Notes shall be unsecured debt securities of the Company. The Notes shall not be convertible to any other securities of the Company.

3.900% SENIOR NOTES DUE 2028

This Global Note designated on the face hereof as 3.900% Senior Notes due 2028 (the "**Notes**") is a duly authorized issue of securities of the Company issued and issuable in one or more series under an indenture, dated as of March 16, 2023 (the "**Base Indenture**"), between the Company and U.S. Bank Trust Company, National Association, as trustee (the "**Trustee**," which term includes any successor trustee under such indenture), to such indenture, as supplemented by an Officers' Certificate dated as of November 10, 2025 establishing the terms of the Notes (the "**Officers' Certificate**," and together with the Base Indenture, the "**Indenture**"), 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. Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Indenture.

The Notes are not subject to a mandatory or optional sinking fund requirement.

The Notes shall be redeemable, at the Company's option, in whole or in part, at any time or from time to time, at the redemption prices described in the Indenture.

The Notes will be subject to a special mandatory redemption (at a price equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest from the date of initial issuance, or the most recent date to which interest has been paid or provided for, whichever is later, to, but not including, the special mandatory redemption date) under certain circumstances described in the Indenture.

If a Change of Control Repurchase Event occurs, unless the Company has exercised its right to redeem all of the Notes as described above, each Holder of the Notes shall have the right to require the Company to repurchase all or any part (equal to $2,000 and integral multiples of $1,000 in excess thereof) of such Holder's Notes pursuant to the offer described in the Indenture, at a purchase price in cash equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase (subject to the right of Holders of record on the relevant Interest Record Date to receive interest due on the relevant Interest Payment Date).

If an Event of Default (as defined in the Indenture) with respect to the Notes of this Series occurs and is continuing, the principal of the Notes of this Series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each Series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time outstanding of each Series to be affected. Without the consent of any Holder of Securities, the Indenture or the Securities may be amended to cure, correct or supplement any ambiguity, omission, defect or inconsistency as to the Securities of such Series or to make any change that does not adversely affect the rights of any Holder of the Securities of such Series in any material respect. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each Series at the time outstanding, on behalf of the Holders of all Securities of such Series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Until such waiver becomes effective, a consent to it by a Holder of this Note is a continuing consent by the Holder and every subsequent Holder of this Note or portion of this Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on this Note. However, any such Holder or subsequent Holder may revoke the consent as to such Holder's Note or portion of this Note if the Trustee receives the notice of revocation before the date of the waiver becomes effective. Any amendment or waiver once effective shall bind every Holder of each Series affected by such amendment or waiver, subject to certain exceptions provided for in the Indenture.

Every amendment to the Indenture or the Securities of one or more Series shall be set forth in a Supplemental Indenture that complies with the TIA as then in effect.

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 interest on this Note at the times and place and at the rate and in the currency herein prescribed.

A Holder shall register the transfer of or exchange Notes in accordance with the Indenture. The Company may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. Neither the Company nor the Registrar shall be required (a) to issue, register the transfer of, or exchange Notes of any Series for the period beginning at the opening of business fifteen days immediately preceding the mailing of a notice of redemption of Notes of such Series selected for redemption and ending at the close of business on the day of such mailing, or (b) to register the transfer of or exchange Notes of any Series selected, called or being called for redemption as a whole or the portion being redeemed of any such Securities selected, called or being called for redemption in part.

The Company may be discharged from its obligations under the Notes and under the Indenture with respect to the Notes except for certain provisions thereof, and may be discharged from obligations to comply with certain covenants contained in the Notes and in the Indenture with respect to the Notes, in each case upon satisfaction of certain conditions specified in the Indenture.

A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under this Note or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting the Note waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Note.

The registered Holder of this Note shall be treated as the owner of it for all purposes.

If funds for the payment of principal or interest remain unclaimed for two years, the Trustee and the Paying Agent will repay the funds to the Company at its written request. After that, all liability of the Trustee and such Paying Agent with respect to such funds shall cease.

The Trustee shall act as the Registrar, Paying Agent and Service Agent (as defined in the Indenture) for the Notes. The Notes shall be issued in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The Notes shall be issued only in registered form without coupons. In the event of a declaration of acceleration of the maturity of the Notes pursuant to the Indenture, 100% of the principal amount of the Notes shall be payable. The Notes shall be issued in United States dollars and principal of and premium, if any, and interest on the Notes shall be paid in United States dollars. The Notes shall be unsecured debt securities of the Company. The Notes shall not be convertible to any other securities of the Company. The Indenture and this Note shall be governed by and construed in accordance with the laws of the State of New York.

In order to comply with applicable tax laws (inclusive of rules, regulations and interpretations promulgated by competent authorities) related to the Notes in effect from time to time ("**Applicable Law**") that a foreign financial institution, issuer, trustee, paying agent or other party is or has agreed to be subject to, the Company agrees (i) upon written request of the Trustee, to provide to the Trustee, to the extent reasonably available to the Company, sufficient information about the parties and/or transactions (including any modification to the terms of such transactions) so the Trustee can determine whether it has tax related obligations under Applicable Law and (ii) that the Trustee shall be entitled to make any withholding or deduction from payments to the extent necessary to comply with Applicable Law for which the Trustee shall not have any liability.

However, any such Holder or subsequent Holder may revoke the consent as to such Holder's Note or portion of this Note if the Trustee receives the notice of revocation before the date of the waiver becomes effective.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each Series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time outstanding of each Series to be affected. Without the consent of any Holder of Securities, the Indenture or the Securities may be amended to cure, correct or supplement any ambiguity, omission, defect or inconsistency as to the Securities of such Series or to make any change that does not adversely affect the rights of any Holder of the Securities of such Series in any material respect. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each Series at the time outstanding, on behalf of the Holders of all Securities of such Series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Until such waiver becomes effective, a consent to it by a Holder of this Note is a continuing consent by the Holder and every subsequent Holder of this Note or portion of this Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on this Note. However, any such Holder or subsequent Holder may revoke the consent as to such Holder's Note or portion of this Note if the Trustee receives the notice of revocation before the date of the waiver becomes effective. Any amendment or waiver once effective shall bind every Holder of each Series affected by such amendment or waiver, subject to certain exceptions provided for in the Indenture.

Every amendment to the Indenture or the Securities of one or more Series shall be set forth in a Supplemental Indenture that complies with the TIA as then in effect.

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 interest on this Note at the times and place and at the rate and in the currency herein prescribed.

A Holder shall register the transfer of or exchange Notes in accordance with the Indenture. The Company may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. Neither the Company nor the Registrar shall be required (a) to issue, register the transfer of, or exchange Notes of any Series for the period beginning at the opening of business fifteen days immediately preceding the mailing of a notice of redemption of Notes of such Series selected for redemption and ending at the close of business on the day of such mailing, or (b) to register the transfer of or exchange Notes of any Series selected, called or being called for redemption as a whole or the portion being redeemed of any such Securities selected, called or being called for redemption in part.

The Company may be discharged from its obligations under the Notes and under the Indenture with respect to the Notes except for certain provisions thereof, and may be discharged from obligations to comply with certain covenants contained in the Notes and in the Indenture with respect to the Notes, in each case upon satisfaction of certain conditions specified in the Indenture.

A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under this Note or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting the Note waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Note.

The registered Holder of this Note shall be treated as the owner of it for all purposes.

If funds for the payment of principal or interest remain unclaimed for two years, the Trustee and the Paying Agent will repay the funds to the Company at its written request. After that, all liability of the Trustee and such Paying Agent with respect to such funds shall cease.

The Trustee shall act as the Registrar, Paying Agent and Service Agent (as defined in the Indenture) for the Notes. The Notes shall be issued in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The Notes shall be issued only in registered form without coupons. In the event of a declaration of acceleration of the maturity of the Notes pursuant to the Indenture, 100% of the principal amount of the Notes shall be payable. The Notes shall be issued in United States dollars and principal of and premium, if any, and interest on the Notes shall be paid in United States dollars. The Notes shall be unsecured debt securities of the Company. The Notes shall not be convertible to any other securities of the Company. The Indenture and this Note shall be governed by and construed in accordance with the laws of the State of New York.

In order to comply with applicable tax laws (inclusive of rules, regulations and interpretations promulgated by competent authorities) related to the Notes in effect from time to time ("**Applicable Law**") that a foreign financial institution, issuer, trustee, paying agent or other party is or has agreed to be subject to, the Company agrees (i) upon written request of the Trustee, to provide to the Trustee, to the extent reasonably available to the Company, sufficient information about the parties and/or transactions (including any modification to the terms of such transactions) so the Trustee can determine whether it has tax related obligations under Applicable Law and (ii) that the Trustee shall be entitled to make any withholding or deduction from payments to the extent necessary to comply with Applicable Law for which the Trustee shall not have any liability.

Re: <u>Amphenol Corporation</u>

To the addressee set forth above:

We have acted as special counsel to Amphenol Corporation, a Delaware corporation (the "***Company***"), in connection with the issuance of $500 million aggregate principal amount of the Company's Floating Rate Senior Notes due 2027 (the "***Floating Rate Notes***"), $750 million aggregate principal amount of the Company's 3.800% Senior Notes due 2027 (the "***2027 Notes***"), $750 million aggregate principal amount of the Company's 3.900% Senior Notes due 2028 (the "***2028 Notes***"), $1,000 million aggregate principal amount of the Company's 4.125% Senior Notes due 2030 (the "***2030 Notes***"), $1,250 million aggregate principal amount of the Company's 4.400% Senior Notes due 2033 (the "***2033 Notes***"), $1,600 million aggregate principal amount of the Company's 4.625% Senior Notes due 2036 (the "***2036 Notes***") and $1,650 million aggregate principal amount of the Company's 5.300% Senior Notes due 2055 (the "***2055 Notes***" and, together with the Floating Rate Notes, the 2027 Notes, the 2028 Notes, the 2030 Notes, the 2033 Notes and the 2036 Notes, the "***Notes***"), under an indenture, dated as of March 16, 2023 between U.S. Bank Trust Company, National Association, as trustee, and the Company (the "***Base Indenture***") and an officers' certificate, dated November 10, 2025, setting forth the terms of each series of the Notes (the "***Officers' Certificate***" and, together with the Base Indenture, the "***Indenture***"), and pursuant to a registration statement on Form S-3 under the Securities Act of 1933, as amended (the "***Act***"), filed with the Securities and Exchange Commission (the "***Commission***") on March 16, 2023 (Registration No. 333-270605) (as amended, the "***Registration Statement***"), a base prospectus, dated March 16, 2023 included in the Registration Statement at the time it originally became effective (the "***Base Prospectus***") and a final prospectus supplement, dated October 27, 2025, filed with the Commission pursuant to Rule 424(b) under the Act on October 28, 2025 (together with the Base Prospectus, the "***Prospectus***").

This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or related prospectus, other than as expressly stated herein with respect to the issue of the Notes.

As such counsel, we have examined such matters of fact and questions of law as we have considered appropriate for purposes of this letter. With your consent, we have relied upon certificates and other assurances of officers of the Company and others as to factual matters without having independently verified such factual matters. We are opining herein as to the internal laws of the State of New York and the Delaware General Corporation Law, and we express no opinion with respect to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction or, in the case of Delaware, any other laws, or as to any matters of municipal law or the laws of any local agencies within any state.

Subject to the foregoing and the other matters set forth herein, it is our opinion that, as of the date hereof, when the Notes have been duly executed, issued, and authenticated in accordance with the terms of the Indenture and delivered against payment therefor in the circumstances contemplated by the form of underwriting agreement most recently filed as an exhibit to the Registration Statement, the Notes will have been duly authorized by all necessary corporate action of the Company and will be legally valid and binding obligations of the Company enforceable against the Company in accordance with their terms.

Our opinions are subject to: (i) the effect of bankruptcy, insolvency, reorganization, fraudulent transfer, moratorium or other similar laws relating to or affecting the rights and remedies of creditors; (ii) the effect of general principles of equity, whether considered in a proceeding in equity or at law (including the possible unavailability of specific performance or injunctive relief), concepts of materiality, reasonableness, good faith and fair dealing, and the discretion of the court before which a proceeding is brought; (iii) the invalidity under certain circumstances under law or court decisions of provisions providing for the indemnification of or contribution to a party with respect to a liability where such indemnification or contribution is contrary to public policy; and (iv) we express no opinion as to (a) any provision for liquidated damages, default interest, late charges, monetary penalties, make-whole premiums or other economic remedies to the extent such provisions are deemed to constitute a penalty; (b) consents to, or restrictions upon, governing law, jurisdiction, venue, arbitration, remedies, or judicial relief; (c) waivers of rights or defenses relating to stay, extension, and usury laws; and waivers of broadly or vaguely stated rights; (d) any provision requiring the payment of attorneys' fees, where such payment is contrary to law or public policy; (e) any provision permitting, upon acceleration of the Notes, collection of that portion of the stated principal amount thereof which might be determined to constitute unearned interest thereon; and (f) the severability, if invalid, of provisions to the foregoing effect.

With your consent, we have assumed (a) that the Indenture and the Notes (collectively, the "***Documents***") have been duly authorized, executed and delivered by the parties thereto other than the Company, (b) that the Documents constitute legally valid and binding obligations of the parties thereto other than the Company, enforceable against each of them in accordance with their respective terms, and (c) that the status of the Documents as legally valid and binding obligations of the parties is not affected by any (i) breaches of, or defaults under, agreements or instruments, (ii) violations of statutes, rules, regulations or court or governmental orders, or (iii) failures to obtain required consents, approvals or authorizations from, or make required registrations, declarations or filings with, governmental authorities.
