The Company, the Guarantor or any of the Guarantor’s Subsidiaries may act in any such capacity.

(15) In order to provide for all payments due on the Notes as the same shall become due, the Company shall cause to be paid to the Paying Agent, no later than 10:00 a.m. London time on the Business Day prior to the payment date of each Note, at such bank as the Paying Agent shall previously have notified the Company, in immediately available funds sufficient to meet all payments due on such Notes.

(16) Notwithstanding any other provision of this Supplemental Indenture, the Trustee and Paying Agent shall be entitled to make a deduction or withholding from any payment which it makes under this Supplemental Indenture for or on account of any present or future taxes, duties or charges if and to the extent so required by any applicable law and any current or future regulations or agreements thereunder or official interpretations thereof or any law implementing an intergovernmental approach thereto or by virtue of the relevant Holder failing to satisfy any certification or other requirements in respect of the Notes, in which event the Trustee or Paying Agent shall make such payment after such withholding or deduction has been made and shall account to the relevant authorities for the amount so withheld or deducted and shall have no obligation to gross up any payment hereunder or pay any additional amount as a result of such withholding tax.

Additional Amounts will not be payable by the Company with respect to a payment made to a Holder of Securities where such Holder is subject to taxation on such payment by a relevant taxing jurisdiction for or on account of any withholding or deduction required to be made from payments in respect of debt securities pursuant to the Dutch Withholding Tax Xxx 0000 (Wet bronbelasting 2021).

(3) Notwithstanding the foregoing, installments of interest whose Stated Maturity is on or prior to the Optional Redemption Date shall be payable on the applicable Interest Payment Date to the Holders of such Notes registered as such at the close of business on the applicable regular record date pursuant to the Notes and the Indenture.

(4) On and after the applicable Optional Redemption Date for any series of Notes, interest shall cease to accrue on the Notes to be redeemed or any portion thereof called for redemption, unless the Company defaults in the payment of the Optional Redemption Price and accrued and unpaid interest and Additional Amounts, if any.

for redemption by the ICSDs in accordance with their respective standard procedures therefor; provided, however, that no Notes of a principal amount of €100,000 or less shall be redeemed in part. The Security Registrar shall record such redemption in the Security Register and shall provide the details of such redemption to the Common Safekeeper. The Trustee shall cause the Common Service Provider to instruct the Common Safekeeper to make such appropriate entries in their records in respect of all Notes redeemed by the Company to reflect such redemption.

(5) Notice of any optional redemption shall be transmitted at least 10 days but not more than 60 days before the applicable Optional Redemption Date to each Holder of the Notes to be redeemed; provided, however, that the Company shall notify the Trustee of the Optional Redemption Date at least 15 days prior to the date of the giving of such notice (unless a shorter notice shall be satisfactory to the Trustee). Such notice shall be provided in accordance with Section 3.02 of the Base Indenture. If the Optional Redemption Price cannot be determined at the time such notice is to be given, the actual Optional Redemption Price applicable to the Notes that are being redeemed, calculated as described above in clause (2), shall be set forth in an Officers’ Certificate of the Company delivered to the Trustee no later than two (2) Business Days prior to the Optional Redemption Date.

(a) If a Change of Control Triggering Event occurs with respect to any series of the Notes, unless the Company shall have redeemed such series of the Notes in full, as set forth in Section 1.4A or 1.4B of this Supplemental Indenture, the Company shall have defeased such series of the Notes or have satisfied and discharged such series of the Notes, as set forth in Article XI of the Base Indenture, the Company shall make an offer (a “Change of Control Offer”) to each Holder of the applicable series of the Notes to repurchase any and all of such Holder’s Notes of such series at a repurchase price in cash equal to 101% of the aggregate principal amount of the Notes to be repurchased (such principal amount to be equal to €100,000

or any integral multiple of €1,000 in excess thereof), plus accrued and unpaid interest, if any, on the Notes to be repurchased up to, but excluding, the date of repurchase (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event, notice shall be delivered to the Holders of Notes of such series describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase such Notes on the date specified in the notice, which date will be no earlier than 15 days and no later than 60 days from the date such notice is delivered (the “Change of Control Payment Date”). Notwithstanding the foregoing, installments of interest whose Stated Maturity is on or prior to the Change of Control Payment Date shall be payable on the applicable Interest Payment Date to the Holders of such Notes registered as such at the close of business on the applicable regular record date pursuant to the Notes and the Indenture.

The Company shall comply in all material respects with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such 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 such securities laws or regulations conflict with this Section 1.5, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 1.5 by virtue of any such conflict.

Section 1.6 Events of Default.

The provisions of Article VI of the Base Indenture shall be applicable to each series of the Notes, except that clauses (1) through (7) of Section 6.01(a) thereof shall be modified with respect to Notes of a series as follows:

The notice required under (3)(ii) above must be sent by either the Trustee or Holders of 25% of the principal amount of the applicable series of Notes;

(4) (A) failure by the Company or the Guarantor to pay indebtedness for money borrowed by the Company or the Guarantor or for which the Company or the Guarantor has guaranteed the payment, in an aggregate principal amount of at least $500,000,000, at the later of final maturity and the expiration of any related applicable grace period and such defaulted payment shall not have been made, waived or extended within 30 days or (B) acceleration of the maturity of any indebtedness for money borrowed by the Company or the Guarantor or for which the Company or the Guarantor has guaranteed the payment, in an aggregate principal amount of at least $500,000,000, if such indebtedness has not been discharged in full or such acceleration has not been rescinded or annulled within 30 days; provided, however, that, if the default under the instrument is cured by the Company or the Guarantor, as applicable, or waived by the holders of the indebtedness, in each case as permitted by the governing instrument, then the Event of Default under the Indenture caused by such default will be deemed likewise to be cured or waived;

(5) the entry by a court having competent jurisdiction of:

(A) an order for relief in respect of the Company or the Guarantor as debtor in an involuntary proceeding under any applicable Bankruptcy Law and such order shall remain unstayed and in effect for a period of 60 consecutive days; or

(B) a final and non-appealable order appointing a Custodian of the Company or the Guarantor, or ordering the winding up or liquidation of the affairs of the Company or the Guarantor, and such order shall remain unstayed and in effect for a period of 60 consecutive days;

Section 2.7 Counterparts.

This Supplemental Indenture may be executed in any number of counterparts each of which shall be an original, but such counterparts shall together constitute but one and the same instrument. The exchange of copies of this Supplemental Indenture and of signature pages by facsimile or electronic format (e.g., “.pdf” or “.tif”) transmission shall constitute effective execution and delivery of this Supplemental Indenture as to the parties hereto and may be used in lieu of the original Supplemental Indenture for all purposes.

The words “execution,” “signed,” “signature,” and words of like import in this Supplemental Indenture, the Indenture or any agreement entered into in connection herewith shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act (e.g. DocuSign).

The Trustee shall have the right to accept and act upon instructions, including funds transfer instructions (“Instructions”) given pursuant to the Indenture and delivered using Electronic Means; provided, however, that the Company shall provide to the Trustee an incumbency certificate listing officers with the authority to provide such Instructions (“Authorized Officers”) and containing specimen signatures of such Authorized Officers, which incumbency certificate shall be amended by the Company whenever a person is to be added or deleted from the listing. If the Company elects to give the Trustee Instructions using Electronic Means and the Trustee in its discretion elects to act upon such Instructions, the Trustee’s understanding of such Instructions shall be deemed controlling. The Company understands and agrees that the Trustee cannot determine the identity of the actual sender of such Instructions and that the Trustee shall conclusively presume that directions that purport to have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustee have been sent by such Authorized Officer. The Company shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustee and that the Company and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Company. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such Instructions

notwithstanding such directions conflict or are inconsistent with a subsequent written instruction. The Company agrees: (i) to assume all risks arising out of the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Issuer; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustee immediately upon learning of any compromise or unauthorized use of the security procedures.

Section 2.11 OFAC Certification and Covenants.

(a) The Company covenants and represents that neither it nor any of its subsidiaries, directors or officers are the target or subject of any sanctions enforced by the US Government, (including, the Office of Foreign Assets Control of the US Department of the Treasury (“OFAC”)), the United Nations Security Council, the European Union, or Her Majesty’s Treasury (collectively “Sanctions”).

It is acknowledged and agreed that the covenants and representations in this Section 2.11 are only sought and given to the extent that to do so would not be unenforceable by or in respect of that person by reason of breach of (i) any provision of Council Regulation (EC) No 2271/96 of 22 November 1996 (or any law or regulation implementing such Regulation in any member state of the European Union) or (ii) Council Regulation (EC) No 2271/96 as it forms part of domestic law in the United Kingdom by virtue of the European Union (Withdrawal) Act 2018 (or any law or regulation implementing such Regulation in the United Kingdom).

This security is one of a duly authorized series of debt securities of Thermo Xxxxxx Scientific (Finance I) B.V., a private limited liability company (besloten vennootschap met beperkte aansprakelijkheid) incorporated under the laws of the Netherlands, with its corporate seat (statutaire zetel) at Breda, the Netherlands, and its registered office at Xxxxxxxxxxxxx 0, 0000 XX Xxxxx, xxx Xxxxxxxxxxx, registered with the Dutch Trade Register of the Chamber of Commerce under number 66428319 (the “Company”), issued or to be issued in one or more series under and pursuant to an Indenture for the Company’s unsecured debt securities, dated as of August 9, 2016 (the “Base Indenture”), duly executed and delivered by and among the Company, Thermo Xxxxxx Scientific Inc., a Delaware corporation (the “Guarantor”) and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), as supplemented by the Third Supplemental Indenture, dated as of October 18, 2021 (the “Supplemental Indenture”), among the Company, the Guarantor and the Trustee. The Notes are subject to a Paying Agency Agreement, dated as of October 18, 2021 (the “Paying Agency Agreement”), between the Company and The Bank of New York Mellon, London Branch, as paying agent (the “Paying Agent”). The Base Indenture as supplemented and amended by the Supplemental Indenture is referred to herein as the “Indenture.” By the terms of the Base Indenture, the debt securities issuable thereunder are issuable in series that may vary as to amount, date of maturity, rate of interest and in other respects as provided in the Base Indenture. This security is one of the series designated on the face hereof (individually, a “Security,” and collectively, the “Securities”), and reference is hereby made to the Indenture for a description of the rights, limitations of rights, obligations, duties and immunities of the Trustee, the Company, the Guarantor and the holders of the Securities (the “Securityholders”). Capitalized terms used herein and not otherwise defined shall have the meanings given them in the Base Indenture or the Supplemental Indenture, as applicable.

1. Interest. The Company promises to pay interest on the principal amount of this Security at an annual rate of [ ]%⁷. The Company will pay interest annually in arrears on [ ] of each year (each such day, an “Interest Payment Date”) until the principal is paid or made available for payment.

In order to provide for all payments due on the Securities as the same shall become due, the Company shall cause to be paid to the Paying Agent, no later than 10:00 a.m. London time on the Business Day prior the payment date of each Security, at such bank as the Paying Agent shall previously have notified to the Company, in immediately available funds sufficient to meet all payments due on such Securities.

2. Method of Payment. The Company will pay interest on the Securities (except defaulted interest), if any, to the persons in whose name such Securities are registered at the close of business on the regular record date referred to on the facing page of this Security for such interest installment. In the event that the Securities or a portion thereof are called for redemption pursuant to Section 1.4A or 1.4B or there is a Change of Control Offer, and the Optional Redemption Date or Change of Control Payment Date, as applicable, is subsequent to a regular record date with respect to any Interest Payment Date and prior to such Interest Payment Date, interest on such Securities shall instead be paid upon presentation and surrender of such Securities as provided in the Indenture. Subject to Section 1.2(13) of the Supplemental Indenture, all payments of principal of, and interest (including Additional Amounts, if any) and premium (if any) on, the Securities shall be payable in euro.

3. Paying Agent and Registrar.

The Company, the Guarantor or any of the Guarantor’s Subsidiaries may act in any such capacity.

4. Indenture. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (“TIA”), as in effect on the date the Indenture is qualified. The Securities are subject to all such terms, and Securityholders are referred to the Indenture and TIA for a statement of such terms. In the event of a conflict between the terms of the Securities and the terms of the Indenture, the terms of the Indenture shall prevail. The Securities are unsecured general obligations of the Company and constitute the series designated on the face hereof as the “[ ]⁸,” initially limited to €[ ]⁹ in aggregate principal amount. The Company shall furnish to any Securityholder upon written request and without charge a copy of the Base Indenture and the Supplemental Indenture.

6. Redemption Upon Changes in Withholding Taxes; Payment of Additional Amounts. The provisions of Sections 15.01 and 15.02 of the Base Indenture and Sections 1.3 and 1.4B of the Supplemental Indenture shall apply to the Securities.

7. Change of Control Triggering Event. Upon the occurrence of a Change of Control Triggering Event, unless the Company has redeemed this Security or the Company has defeased this Security or satisfied and discharged this Security, the holder of this Security shall have the right to require that the Company purchase all or a portion (such principal amount to be equal to €100,000 or any integral multiple of €1,000 in excess thereof) of this Security at a purchase price equal to 101% of the aggregate principal amount repurchased plus accrued and unpaid interest, if any, on the amount to be repurchased up to but excluding the date of purchase. Within 30 days following any Change of Control Triggering Event, the Company shall send, by first class mail, a notice to each Holder, in accordance with Section 1.5 of the Supplemental Indenture, with a copy to the Trustee, which notice shall govern the terms of the Change of Control Offer.

8. Denominations, Transfer, Exchange. The Securities are in registered form without coupons in the denominations of €100,000 or any integral multiple of €1,000 in excess thereof. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture.

No service charge shall be made for any registration of transfer or exchange, but a Securityholder may be required to pay any applicable taxes or other governmental charges.

9. Persons Deemed Owners. The registered Securityholder may be treated as its owner for all purposes.

10. Repayment to the Company. Any funds or Governmental Obligations deposited with any paying agent or the Trustee, or then held by the Company, in trust for payment of principal of, premium, if any, or interest on the Securities that are not applied but remain unclaimed by the holders of such Securities for at least one year after the date upon which the principal of, premium, if any, or interest on such Securities shall have respectively become due and payable, shall be repaid to the Company, as applicable, or (if then held by the Company) shall be discharged from such trust. After return to the Company, Holders entitled to the money or securities must look to the Company, as applicable, for payment as unsecured general creditors.

A-7

11. Amendments, Supplements and Waivers. 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 Guarantor and the rights of the Holders of the Securities to be affected under the Indenture at any time by the Company, the Guarantor and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of a majority in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Securities, to waive compliance by the Company or the Guarantor with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

12. Defaults and Remedies. If an Event of Default with respect to the Securities occurs and is continuing, the Trustee or the holders of at least 25% in aggregate principal amount of the Securities then Outstanding, by notice in writing to the Company (and to the Trustee if notice is given by such holders), may declare the entire principal of, premium, if any, and accrued interest, if any, of such Securities due and payable immediately. Subject to the terms of the Indenture, if an Event of Default under the Indenture shall occur and be continuing, the Trustee shall be under no obligation to exercise any of its rights or powers under the Indenture at the request or direction of any of the holders, unless such holders have offered the Trustee indemnity satisfactory to it. Upon satisfaction of certain conditions set forth in the Indenture, the holders of a majority in principal amount of the Outstanding Securities shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities.

13. Trustee, Paying Agent and Security Registrar May Hold Securities.
