The actual Redemption Price, calculated as described above, will be set forth in an Officer’s Certificate of the Company delivered to the Trustee and to Holders of the Notes no later than two Business Days prior to the Redemption Date. The Company may provide in a notice of redemption that payment of such Redemption Price and performance of the Company’s obligations with respect to such redemption or purchase may be performed by another Person.

9

(d) If less than all of the Notes of a particular series are redeemed at any time and the Notes of such series are Global Notes held by the Depositary, the Depositary will select the Notes to be redeemed in accordance with its operational arrangements. If the Notes are not Global Notes held by the Depositary, the Company will select Notes called for redemption in part on a pro rata basis or on as nearly a pro rata basis as is practicable; provided that Notes in principal amounts of $2,000 or less shall be redeemed in whole and not in part. In the case of Notes represented by a Global Security, the outstanding principal amount of the Global Security representing the Notes will be reduced by book-entry. Notes called for redemption become due on the Redemption Date, subject to the satisfaction of any conditions precedent provided in the notice of redemption. On and after the Redemption Date, interest stops accruing on Notes or portions of them called for redemption (unless there is a default in the payment thereof).

(e) If a Redemption Date falls on a date that is not a Business Day, then the Redemption Price will be paid on the next day that is a Business Day, and no interest on such payment will accrue for the period from and after such Redemption Date.

Section 3.04. Repurchase of Notes upon a Change of Control.

(a) If a Change of Control Triggering Event occurs with respect to the Notes, unless the Company has exercised its right to redeem the Notes as provided in Section 3.03 hereof, each Holder of Notes will have the right to require the Company to make an offer (a “Change of Control Offer”) to each Holder of a Note to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes on the terms set forth in this Section 3.04 and in the Notes. In a Change of Control Offer, the Company shall offer payment in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to the date of repurchase (a “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event or, at the Company’s option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, the Company shall send a notice to Holders of the Notes, describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase the Notes on the date specified in the notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is sent (a “Change of Control Payment Date”), pursuant to the procedures required by the Notes and described in such notice. The notice shall, if sent prior to the date of consummation of the Change of Control, state that the Change of Control Offer is conditioned on the Change of Control occurring on or prior to the Change of Control Payment Date.

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

(i) accept for payment all Notes or portions of Notes properly tendered pursuant to the applicable Change of Control Offer;

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

(iii) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being repurchased.

10

(c) The Company shall not be required to make a Change of Control Offer with respect to the Notes upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and the third party purchases all Notes properly tendered and not withdrawn under its offer. In addition, the Company shall not repurchase any Notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Indenture, other than a default in the payment of the Change of Control Payment on the Change of Control Payment Date.

(d) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and 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 Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the Company shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Offer provisions of the Notes by virtue of any such conflict and compliance.

(e) If Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company, as described in this Section 3.04, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company shall have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer described herein, to redeem all Notes that remain outstanding following such purchase at a Redemption Price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date (subject to the right of Holders of record on a record date to receive interest on the relevant Interest Payment Date).

Section 3.05. Special Mandatory Redemption.

(a) If the closing of the FLIR Acquisition has not occurred on or prior to the earlier of (i) December 31, 2021 and (ii) the date the Merger Agreement, including any amendment thereof, is terminated, according to its terms (each, a “Special Mandatory Redemption Event”), the Company shall redeem the 2023 Notes, the 2024 Notes, the 2026 Notes, and the 2031 Notes in whole at a special mandatory redemption price equal to 101% of the aggregate principal amount of such Notes, plus accrued and unpaid interest on the principal amount of such Notes to but excluding the Special Mandatory Redemption Date (as defined below) (the “Special Mandatory Redemption Price”). Upon the occurrence of a Special Mandatory Redemption Event, the Company shall promptly (but in no event later than five calendar days following such Special Mandatory Redemption Event) cause notice to be delivered electronically or mailed, with a copy to the Trustee, to each Holder at its registered address (such date of notification to the Holders, the “Redemption Notice Date”). The notice shall inform Holders that the Notes will be redeemed on the tenth calendar day (or if such day is not a Business Day, the first Business Day thereafter) following the Redemption Notice Date (such date, the “Special Mandatory Redemption Date”) and that all of the outstanding Notes to be redeemed shall be redeemed at the Special Mandatory Redemption Price on the Special Mandatory Redemption Date automatically and without any further action by the Holders of the Notes. On the Business Day immediately preceding the Special Mandatory Redemption Date, the Company shall deposit with the Trustee funds sufficient to pay the Special Mandatory Redemption Price. If such deposit is made as provided above, the Notes to be redeemed will cease to bear interest on and after the Special Mandatory Redemption Date.

(b) Upon the completion of the FLIR Acquisition, the foregoing provisions regarding special mandatory redemption will cease to apply.

(c) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, merger, conveyance, transfer or lease and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture comply with this Article.

If, upon any such consolidation or merger, or upon any such conveyance, sale, transfer or lease, as provided above, any Principal Property of the Company or any capital stock or indebtedness of any Restricted Subsidiary, owned immediately prior to the transaction, would thereupon become subject to any mortgage, security interest, pledge or lien securing any indebtedness for borrowed money of, or guaranteed by, such other corporation (other than any mortgage, security interest, pledge or lien permitted as described in Section 4.01), the Company, prior to such consolidation, merger, lease, sale or transfer, will, by executing and delivering to the Trustee a supplemental indenture, secure the due and punctual payment of the principal of, and any premium and interest on, the Notes (together with, if the Company shall so determine, any other indebtedness of, or guaranteed by, the Company or any Restricted Subsidiary and then existing or thereafter created) equally and ratably with (or, at the Company’s option, prior to) the indebtedness secured by such mortgage, security interest, pledge or lien.”

ARTICLE 7

GUARANTEE

Section 7.01. Guarantee.

(a) Subject to this Article 7, each Guarantor, jointly and severally, and fully and unconditionally, guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, the Notes or the obligations of the Company hereunder or thereunder, that: (i) the principal of, premium, if any, and interest on the Notes shall be promptly paid in full when due, whether at maturity, by

17

acceleration, redemption or otherwise, and interest on the overdue principal of, premium, if any, and interest on the Notes, if lawful (subject in all cases to any applicable grace period provided herein), and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder, including any obligations to repurchase the Notes from the Holders, shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (ii) in case of any extension of time of payment or renewal of the Notes or any of such other obligations, the same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, each Guarantor shall be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b) To the maximum extent permitted under applicable law, the obligations of any Guarantor hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Subject to Section 5.07 of the Base Indenture, each Guarantor shall waive diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that this Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and the Indenture.

(c) If any Holder or the Trustee is required by any court or otherwise to return to the Company, any Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to any of the Company or any Guarantors, any amount paid by any of them to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect.

(d) No Guarantor shall be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. As between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 5 for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article 5, such obligations (whether or not due and payable) shall forthwith become due and payable by any Guarantors for the purpose of this Guarantee. Any Guarantor that makes a payment under its Guarantee shall have the right to seek contribution from any non-paying Guarantor, so long as the exercise of such right does not impair the rights of the Holders under the Guarantee.

Section 7.02. Limitation on Guarantor Liability.

The maximum aggregate amount guaranteed hereunder by any Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering the Indenture, as it relates to such Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

Section 7.03. Execution and Delivery of Guarantee.

(a) To evidence its Guarantee set forth in Section 7.01, each Guarantor agrees that a supplemental indenture substantially in the form attached hereto as Exhibit F shall be executed on behalf of such Guarantor by one of its Officers.

18

(b) Each Guarantee set forth in Section 7.01 shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Guarantee.

(c) If an Officer whose signature is on any Guarantee no longer holds that office at the time the Trustee authenticates the Security on which any Guarantee is endorsed, the Guarantee shall be valid nevertheless.

(d) The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee set forth in the Indenture on behalf of any Guarantor.

Section 7.04. Guarantors May Consolidate, etc., on Certain Terms.

(a) Except as set forth in Section 7.05, a Guarantor may not sell, lease, transfer, convey or otherwise dispose of all or substantially all of its properties or assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person), another Person, other than the Company or another Guarantor, unless (1) immediately after giving effect to that transaction, no Default or Event of Default exists and (2) the Person acquiring the property or assets in any such sale, lease, transfer, conveyance or other disposition or the Person formed by or surviving any such consolidation or merger (if other than the Guarantor) is organized or existing under the laws of the United States, any state thereof or the District of Columbia and assumes all the obligations of that Guarantor under the Indenture and its Guarantee pursuant to a supplemental indenture satisfactory to the Trustee.

(b) In case of any such consolidation, merger, sale, lease, transfer, conveyance or other disposition governed by Section 7.04(a)(2), upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Guarantee endorsed upon the Securities and the due and punctual performance of all of the covenants and conditions of the Indenture to be performed by a Guarantor, such successor Person shall succeed to and be substituted for a Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Guarantees so issued shall in all respects have the same legal rank and benefit under the Indenture as the Guarantees theretofore and thereafter issued in accordance with the terms of the Indenture as though all of such Guarantees had been issued at the date of the execution hereof.

Section 7.05. Release of a Guarantor.

(a) Without prejudice to Section 4.03, any Guarantor shall be automatically released and relieved of any obligations under its Guarantee, (i) in connection with any sale or other disposition of all of the capital stock of such Guarantor, or all or substantially all of such Guarantor’s assets, to a Person that is not (either before or after giving effect to such transaction) the Company or a Domestic Subsidiary of the Company required to deliver a Guarantee under Section 4.03; (ii) upon Legal Defeasance or Covenant Defeasance (as defined below) as permitted under the Indenture; or (iii) upon release or discharge of all guarantees by such Guarantor of all other indebtedness of the Company, except a discharge or release by or as a result of payment under such guarantees of other indebtedness of the Company. Notwithstanding the foregoing, the Company shall not, directly or indirectly, sell or make any other disposition of all of the capital stock of any Guarantor or of all or substantially all of any Guarantor’s assets to a Person that is not a Domestic Subsidiary solely for the purpose of causing such Guarantor to be released from its Guarantee.

19

(b) Upon delivery by the Company to the Trustee of an Officer’s Certificate to the effect that one of the foregoing requirements has been satisfied and the conditions to the release of a Guarantor under this Section 7.05 have been met, the Trustee shall execute any documents reasonably required in order to evidence the release of such Guarantor from its obligations under its Guarantee. Any Guarantor not released from its obligations under its Guarantee shall remain liable for the full amount of principal of, premium, if any, and interest on the Securities as provided in this Article 7.

The Company will pay interest hereon (except defaulted interest) to the Persons who are registered Holders at the close of business on the March 15 and September 15 immediately preceding the interest payment date (whether or not a Business Day). Holders do not have to surrender Notes to a Paying Agent to collect principal payments.

If a Holder has given wire transfer instructions to the Company, the Company will pay, or cause to be paid by the Paying Agent, all principal (and premium, if any) and interest on that Holder’s Notes in accordance with those instructions. All other payments on the Notes will be made at the office or agency of the Paying Agent and Registrar unless the Company elects to make interest payments by check mailed to the Holders at their address set forth in the register of Holders.

3. Paying Agent and Registrar. Initially, U.S. Bank National Association (the “Trustee”) will act as a Paying Agent and Security Registrar. The Company may change any Paying Agent or Security Registrar without notice to the Holders. The Company or any of its Subsidiaries may act as Paying Agent or Security Registrar.

4. Indenture. This Note is one of the series designated on the face hereof. This Note is one of a duly authorized issue of securities of the Company issued and to be issued in one or more series under an Indenture, dated as of March 22, 2021 (the “Base Indenture”), between the Company and the Trustee, as supplemented by the First Supplemental Indenture, dated as of March 22, 2021 (the “Supplemental Indenture” and, together with the Base Indenture, as supplemented by the Supplemental Indenture, the “Indenture”).

The Company may provide in such notice that payment of such price and performance of the Company’s obligations with respect to such redemption or purchase may be performed by another Person.

In addition, the Notes may be subject to special mandatory redemption as further described in the First Supplemental Indenture.

The Company will select Notes called for redemption in part pursuant to paragraph 5 on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to procedures of the Depositary); provided that Notes in principal amount of $2,000 or less shall be redeemed in whole and not in part. A new Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note, or in the case of Notes represented by a Global Security, the outstanding principal amount of such Global Security will be reduced by book-entry. Notes called for redemption pursuant to paragraph 5 become due on the Redemption Date.

Notices of redemption pursuant to paragraph 5 shall be mailed by first class mail (or sent electronically) at least 10 but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at its registered address with a copy to the Trustee. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed.

8. Change of Control. Upon the occurrence of a Change of Control Triggering Event, unless all Notes have been called for redemption pursuant to paragraph 5, each Holder of Notes of this series shall have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such Notes at an offer price in cash equal to the Change of Control Payment. The Change of Control Offer will be made in accordance with the terms specified in the Indenture.

10. Persons Deemed Owners. The registered Holder of this Note may be treated as the owner of this Note for all purposes.

11. Unclaimed Money. If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent will pay the money back to the Company at its written request. After that, Holders entitled to the money must look to the Company for payment as general creditors unless an “abandoned property” law designates another Person.

12. Amendment, Waiver, Etc. The Company and the Trustee (if a party thereto) may, without the consent of the Holders of any outstanding Notes, amend or waive the Indenture or the Notes for certain specified purposes, including, among other things, curing ambiguities, defects or inconsistencies, maintaining the qualification of the Indenture under the Trust Indenture Act, providing for the assumption by a successor to the Company of its obligations under the Indenture and making any change that does not adversely affect the rights of any Holder in any material respect. Other amendments of the Indenture or the Notes may be made by the Company and the Trustee with the consent of the Holders of not less than a majority of the aggregate principal amount of the outstanding Notes, subject to certain exceptions requiring the consent of the Holders of the particular Notes to be affected.

14. Defaults and Remedies. Events of Default are set forth in the Supplemental Indenture. Subject to certain limitations in the Indenture, if an Event of Default (other than an Event of Default specified in Sections 5.01(e) and 5.01(f) of the Supplemental Indenture) occurs and is continuing, then, and in each and every such case, either the Trustee, by notice in writing to the Company, or the Holders of not less than 25% of the principal amount of the Notes then outstanding, by notice in writing to the Company and the Trustee, may, and the Trustee at the request of such Holders shall, declare due and payable, if not already due and payable, the principal of and any accrued and unpaid interest on all of the Notes; and upon any such declaration all such amounts upon such Notes shall become and be immediately due and payable, anything in the Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified in Sections 5.01(e) and 5.01(f) of the Supplemental Indenture occurs, then the principal of and any accrued and unpaid interest on all of the Notes shall immediately become due and payable without any declaration or other act on the part of the Trustee or any Holder. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require security or indemnity satisfactory to it in its sole discretion before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power, provided, that the Trustee will be entitled to refuse to follow any such direction that conflicts with law or the Indenture or that the Trustee determines in good faith is unduly prejudicial to the rights of other Holders or could, in reasonable likelihood, impose personal liability upon the Trustee, unless the Trustee is offered, and if requested, provided indemnity satisfactory to it. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal, premium, if any, or interest on the Notes) if it determines that withholding notice is in their best interests.

15. Trustee Dealings with Company. Subject to certain limitations imposed by the Trust Indenture Act, the Trustee, in its individual or any other capacity, may make loans to, accept deposits from, perform services for or otherwise deal with the Company or any Affiliate thereof, with the same rights it would have as if it were not Trustee.

16. No Recourse Against Others. No past, present or future director, officer, employee, incorporator, agent, member or stockholder or Affiliate of the Company, as such, shall have any liability for any obligations of the Company under the Notes, the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liabilities. The waiver and release are part of the consideration for issuance of the Notes.

This Note is one of a duly authorized issue of securities of the Company issued and to be issued in one or more series under an Indenture, dated as of March 22, 2021 (the “Base Indenture”), between the Company and the Trustee, as supplemented by the First Supplemental Indenture, dated as of March 22, 2021 (the “Supplemental Indenture” and, together with the Base Indenture, as supplemented by the Supplemental Indenture, the “Indenture”). This is one of an issue of Notes of the Company issued, or to be issued, under the Indenture.

Subject to certain limitations in the Indenture, if an Event of Default (other than an Event of Default specified in Sections 5.01(e) and 5.01(f) of the Supplemental Indenture) occurs and is continuing, then, and in each and every such case, either the Trustee, by notice in writing to the Company, or the Holders of not less than 25% of the principal amount of the Notes then outstanding, by notice in writing to the Company and the Trustee, may, and the Trustee at the request of such Holders shall, declare due and payable, if not already due and payable, the principal of and any accrued and unpaid interest on all of the Notes; and upon any such declaration all such amounts upon such Notes shall become and be immediately due and payable, anything in the Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified in Sections 5.01(e) and 5.01(f) of the Supplemental Indenture occurs, then the principal of and any accrued and unpaid interest on all of the Notes shall immediately become due and payable without any declaration or other act on the part of the Trustee or any Holder. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require security or indemnity satisfactory to it in its sole discretion before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power, provided, that the Trustee will be entitled to refuse to follow any such direction that conflicts with law or the Indenture or that the Trustee determines in good faith is unduly prejudicial to the rights of other Holders or could, in reasonable likelihood, impose personal liability upon the Trustee, unless the Trustee is offered, and if requested, provided indemnity satisfactory to it. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal, premium, if any, or interest on the Notes) if it determines that withholding notice is in their best interests.

15. Trustee Dealings with Company. Subject to certain limitations imposed by the Trust Indenture Act, the Trustee, in its individual or any other capacity, may make loans to, accept deposits from, perform services for or otherwise deal with the Company or any Affiliate thereof, with the same rights it would have as if it were not Trustee.

16. No Recourse Against Others. No past, present or future director, officer, employee, incorporator, agent, member or stockholder or Affiliate of the Company, as such, shall have any liability for any obligations of the Company under the Notes, the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liabilities. The waiver and release are part of the consideration for issuance of the Notes.

17. Discharge; Defeasance. The Company’s obligations pursuant to the Indenture will be discharged, except for obligations pursuant to certain sections thereof, subject to the terms of the Indenture, upon the payment of all the Notes or upon the irrevocable deposit with the Trustee of United States dollars or Government Obligations sufficient to pay when due principal of and interest on the Notes to maturity or redemption.

The Company shall pay interest on overdue principal and on overdue interest (to the full extent permitted by law) at the rate borne by the Notes.

2. Method of Payment. The Company will pay interest hereon (except defaulted interest) to the Persons who are registered Holders at the close of business on the March 15 and September 15 immediately preceding the interest payment date (whether or not a Business Day). Holders do not have to surrender Notes to a Paying Agent to collect principal payments.

If a Holder has given wire transfer instructions to the Company, the Company will pay, or cause to be paid by the Paying Agent, all principal (and premium, if any) and interest on that Holder’s Notes in accordance with those instructions. All other payments on the Notes will be made at the office or agency of the Paying Agent and Registrar unless the Company elects to make interest payments by check mailed to the Holders at their address set forth in the register of Holders.

3. Paying Agent and Registrar. Initially, U.S. Bank National Association (the “Trustee”) will act as a Paying Agent and Security Registrar. The Company may change any Paying Agent or Security Registrar without notice to the Holders. The Company or any of its Subsidiaries may act as Paying Agent or Security Registrar.

4. Indenture. This Note is one of the series designated on the face hereof. This Note is one of a duly authorized issue of securities of the Company issued and to be issued in one or more series under an Indenture, dated as of March 22, 2021 (the “Base Indenture”), between the Company and the Trustee, as supplemented by the First Supplemental Indenture, dated as of March 22, 2021 (the “Supplemental Indenture” and, together with the Base Indenture, as supplemented by the Supplemental Indenture, the “Indenture”). This is one of an issue of Notes of the Company issued, or to be issued, under the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb), as amended from time to time (the “Trust Indenture Act”). The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of them. Capitalized and certain other terms used herein and not otherwise defined have the meanings set forth in the Indenture.

5. Optional Redemption; Special Mandatory Redemption. The Notes of this series are subject to redemption at any time or from time to time, prior to January 2, 2031, in whole or in part, at the Company’s option 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 of principal and interest on the Notes to be redeemed that would be due at maturity of such Notes (exclusive of interest accrued to the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 20 basis points, plus accrued and unpaid interest thereon to, but excluding, the Redemption Date. In addition, the Notes are subject to redemption at any time or from time to time, in whole or in part, at the Company’s option, from and after January 2, 2031, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid

E-5

interest, if any, on such Notes to, but excluding, the Redemption Date. The Company may provide in such notice that payment of such price and performance of the Company’s obligations with respect to such redemption or purchase may be performed by another Person. Any such notice may, at the Company’s discretion, be subject to the satisfaction of one or more conditions precedent. In addition, the Notes may be subject to special mandatory redemption as further described in the First Supplemental Indenture.

Any notice to holders of Notes of a redemption pursuant to this paragraph 5 will include the appropriate calculation of the Redemption Price, but does not need to include the Redemption Price itself. The actual Redemption Price, calculated as described above, will be set forth in an Officer’s Certificate of the Company delivered to the Trustee no later than two Business Days prior to the Redemption Date.

6. Redemption Procedures. The Company will select Notes called for redemption in part pursuant to paragraph 5 on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to procedures of the Depositary); provided that Notes in principal amount of $2,000 or less shall be redeemed in whole and not in part. A new Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note, or in the case of Notes represented by a Global Security, the outstanding principal amount of such Global Security will be reduced by book-entry. Notes called for redemption pursuant to paragraph 5 become due on the Redemption Date. On and after the Redemption Date, interest stops accruing on Notes or portions of them called for redemption (unless there is a default in the payment thereof).

7. Notice of Redemption. Notices of redemption pursuant to paragraph 5 shall be mailed by first class mail (or sent electronically) at least 10 but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at its registered address with a copy to the Trustee. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed.

8. Change of Control. Upon the occurrence of a Change of Control Triggering Event, unless all Notes have been called for redemption pursuant to paragraph 5, each Holder of Notes of this series shall have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such Notes at an offer price in cash equal to the Change of Control Payment. The Change of Control Offer will be made in accordance with the terms specified in the Indenture.

9. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay to it any taxes and fees required by law or permitted by the Indenture.

10. Persons Deemed Owners. The registered Holder of this Note may be treated as the owner of this Note for all purposes.

11. Unclaimed Money. If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent will pay the money back to the Company at its written request. After that, Holders entitled to the money must look to the Company for payment as general creditors unless an “abandoned property” law designates another Person.

12. Amendment, Waiver, Etc. The Company and the Trustee (if a party thereto) may, without the consent of the Holders of any outstanding Notes, amend or waive the Indenture or the Notes for certain specified purposes, including, among other things, curing ambiguities, defects or inconsistencies, maintaining the qualification of the Indenture under the Trust Indenture Act, providing for the assumption by a successor to the
