Pursuant to Section 2.2 of the Indenture

Reference is made to the Indenture (the “Indenture”), dated as of November 5, 2009, between Amphenol Corporation, a Delaware corporation (the “Company”), and The Bank of New York Mellon, as trustee (the “Trustee”). Capitalized terms used but not otherwise defined herein shall have the respective meanings ascribed to them in the Indenture.

Pursuant to Section 2.2 of the Indenture, the Company hereby certifies, through its Chief Financial Officer, Craig A. Lampo, and its Secretary, Lance D’Amico, as follows:

1. Pursuant to (i) an Action by Unanimous Written Consent of the Board of Directors (the “Board of Directors”) of the Company taken as of September 3, 2019, including authority delegated by the Board of Directors to the Pricing Committee thereof and (ii) an Action by Unanimous Written Consent of the Pricing Committee of the Board of Directors taken as of September 4, 2019 (the “Pricing Committee Consent”), the Company has created a series of senior debt securities of the Company, designated as the 2.800% Senior Notes due 2030 (the “Notes”), to be issued under the Indenture, and authorized the sale of up to $1,250,000,000 aggregate principal amount of the Notes.

2. The terms of the Notes as authorized by and determined pursuant to the Pricing Committee Consent, are as follows:

(a) The title of the Notes shall be 2.800% Senior Notes due 2030 (CUSIP/ISIN: 032095 AJ0 / US032095AJ08).

(b) The price at which the Notes will be issued shall be 99.920% of the principal amount of the Notes.

(c) The maximum aggregate principal amount of the Notes shall be $900,000,000.

(d) The principal of the Notes shall be payable on February 15, 2030 (the “Maturity Date”).

(e) The Notes shall bear interest at an annual rate of 2.800% from September 10, 2019, payable semi-annually in arrears on February 15 and August 15 of each year (the “Interest Payment Dates”), commencing February 15, 2020 until the principal of the Notes is paid or made available for payment. The interest so payable shall be paid to the Persons in whose name the Notes are registered at the close of business on February 1 or August 1 (the “Interest Record Dates”) (whether or not a Business Day (as defined in the Indenture)) immediately preceding such February 15 or August 15, respectively. The amount of interest payable on any Interest Payment Date shall be computed on the basis of a 360-day year consisting of twelve 30-day months. In the event that any Interest Payment Date, any redemption date or the Maturity Date falls on a day that is not a Business Day, the required payment of principal, premium, if any, and interest will be made on the next succeeding Business Day as if made on the date that payment was due and no interest will accrue on the amount so payable for the period from and after such Interest Payment Date, such redemption date or Maturity Date, as the case may be, to the date of that payment on that next succeeding Business Day.

1

(f) The place where: (i) principal of and premium, if any, and interest on the Notes shall be payable, (ii) the Notes may be surrendered for registration of transfer or exchange and (iii) notices and demands to or upon the Company in respect of the Notes and the Indenture may be served, shall be at the Company’s office or agency in Pittsburgh (which initially shall be the corporate trust office of the Trustee at: 500 Ross Street, 12th Floor, Pittsburgh, PA 15262), provided that, at the Company’s option, payment of interest may be made by check mailed to the registered Holders of the Notes at their registered addresses.

(g) Prior to the Par Call Date (as defined herein), the Notes may be redeemed at the Company’s option, in whole or in part, at any time or from time to time, at a redemption price equal to the greater of:

(i)         100% of the principal amount of the Notes to be redeemed; and

(ii)        the sum of the present values of the Remaining Scheduled Payments (as defined below) of the Notes being redeemed, discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below), plus 25 basis points, plus, in each case of clauses (i) and (ii) of this Section 2(g), accrued and unpaid interest thereon to, but not including, the date of redemption.

On or after the Par Call Date, the Company may redeem the Notes in whole or in part, at its option, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but not including, the date of redemption.

If the date of redemption is on or after an Interest Record Date and on or before the related Interest Payment Date, the 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 whose Notes will be subject to redemption by the Company.

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

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Notes to be redeemed (assuming that the Notes matured on the Par Call Date) that would be used, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Notes (assuming that the Notes matured on the Par Call Date).

2

“Comparable Treasury Price” means, with respect to any date of redemption, (a) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (b) if fewer than four such Reference Treasury Dealer Quotations are provided to us, the average of all such quotations.

“Independent Investment Banker” means the Reference Treasury Dealer appointed by the Company.

“Par Call Date” means November 15, 2029 (three months prior to the Maturity Date).

“Reference Treasury Dealer” means each of (i) Citigroup Global Markets Inc., J.P. Morgan Securities LLC and a primary U.S. Government securities dealer in New York City selected by MUFG Securities Americas Inc. (each, a “Primary Treasury Dealer”), and their respective successors, provided, however, that if any of the foregoing ceases to be a Primary Treasury Dealer, the Company shall substitute therefor another Primary Treasury Dealer; and (ii) any other Primary Treasury Dealers selected by the Company.

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

“Remaining Scheduled Payments” means, with respect to each Note to be redeemed, the remaining scheduled payments of the principal (or of the portion) thereof and interest thereon that would be due after the related date of redemption therefor but for such redemption (assuming that the Notes matured on the Par Call Date); provided, however, that, if that date of redemption is not an Interest Payment Date with respect to such Note, the amount of the next succeeding scheduled interest payment thereon will be reduced by the amount of interest accrued thereon to that date of redemption.

“Treasury Rate” means, with respect to any date of redemption, the rate per annum equal to the semi-annual equivalent yield to maturity, computed as of the second Business Day immediately preceding that date of redemption, of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that date of redemption.

Notice of any redemption shall be mailed at least 15 days but not more than 60 days before the date of redemption to each Holder of Notes to be redeemed. If less than all the Notes are to be redeemed, the Notes to be redeemed shall be selected in accordance with the Depository’s applicable procedures. Unless the Company defaults in payment of the redemption price, on and after the date of redemption, interest shall cease to accrue on the Notes or portions thereof called for redemption.

(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 “Change of Control Offer”), 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:

(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 “Change of Control Payment”);

(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:

(1) accept for payment all Notes or portions of Notes (equal to $2,000 and integral multiples of $1,000 in excess thereof) properly tendered pursuant to the Change of Control Offer;

(2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes so tendered; and

(3) 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 be required to authenticate and deliver a new note or notes as provided below.

The Trustee shall promptly 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 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.

“Rating Decline” means, with respect to a Change of Control, the Notes cease to be rated Investment Grade by each Rating Agency on any date during the period (“Trigger Period”) from the date of the public notice of an arrangement that could result in such Change of Control until 60 days following the consummation of such Change of Control (which Trigger Period will be extended for so long as the rating on the Notes is under publicly announced consideration for a possible downgrade by either of the Rating Agencies).
