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

(A) an order for relief in respect of the Company 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

1.30% Senior Notes due 2017

This security is one of a duly authorized series of debt securities of Thermo Xxxxxx Scientific Inc., a Delaware corporation (the “Company”), issued or to be issued in one or more series under and pursuant to an Indenture for the Company’s unsubordinated debt securities, dated as of November 20, 2009 (the “Base Indenture”), duly executed and delivered by and among the Company and The Bank of New York Mellon Trust Company, N.A. (the “Trustee”), as supplemented by the Sixth Supplemental Indenture, dated as of December 11, 2013 (the “Sixth Supplemental Indenture”), by and between the Company and the Trustee. The Base Indenture as supplemented and amended by the Sixth 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 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 Sixth Supplemental Indenture, as applicable.

1. Interest. The Company promises to pay interest on the principal amount of this Security at an annual rate of 1.30%. The Company will pay interest semi-annually on February 1 and August 1 of each year (each such day, an “Interest Payment Date”) until the principal is paid or made available for payment. If any Interest Payment Date, redemption date or maturity date of this Security is not a Business Day, then payment of interest or principal (and premium, if any) shall be made on the next succeeding Business Day with the same force and effect as if made on the date such payment was due, and no interest shall accrue for the period after such date to the date of such payment on the next succeeding Business Day. Interest on the Securities will accrue from the most recent date to which interest has been paid or duly made available for payment or, if no interest has been paid, from the date of issuance; provided that, if there is no existing Default in the payment of interest, and if this Security is authenticated between a regular record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; and provided, further, that the first Interest Payment Date shall be August 1, 2014. Interest will be calculated on the basis of a 360-day year of twelve 30-day months.

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 either an optional redemption or a Special Mandatory Redemption) or there is a Change of Control Offer, and the Optional Redemption Date, the Special Mandatory Redemption Date or the 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 will instead be paid upon presentation and surrender

- 4 -

of such Securities as provided in the Indenture. The principal of and the interest on the Securities shall be payable in the coin or currency of the United States of America that at the time is legal tender for public and private debt, at the office or agency of the Company maintained for that purpose in accordance with the Indenture.

3. Paying Agent and Registrar. Initially, The Bank of New York Mellon Trust Company, N.A., the Trustee, will act as paying agent and Security Registrar. The Company may change or appoint any paying agent or Security Registrar without notice to any Securityholder. The Company or any of their 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 (“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 “1.30% Senior Notes due 2017”, initially limited to $900,000,000 in aggregate principal amount. The Company will furnish to any Securityholder upon written request and without charge a copy of the Base Indenture and the Sixth Supplemental Indenture.

The Company shall not be required to make sinking fund payments with respect to the Securities.

6. 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 will have the right to require that the Company purchase all or a portion (such principal amount to be equal to $2,000 or any integral multiple of $1,000 in excess of $2,000), 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 1.4(1)(a) of the Sixth Supplemental Indenture, with a copy to the Trustee, which notice shall govern the terms of the Change of Control Offer.

7. Denominations, Transfer, Exchange. The Securities are in registered form without coupons in the denominations of $2,000 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. The Securities may be presented for exchange or for registration of transfer (duly endorsed or with the form of transfer endorsed thereon duly executed if so required by the Company or the Security Registrar) at the office of the Security Registrar or at

- 5 -

the office of any transfer agent designated by the Company for such purpose. No service charge will be made for any registration of transfer or exchange, but a Securityholder may be required to pay any applicable taxes or other governmental charges. If the Securities are to be redeemed, the Company will not be required to: (i) issue, register the transfer of, or exchange any Security during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of less than all of the outstanding Securities of the same series and ending at the close of business on the day of such mailing; (ii) register the transfer of or exchange any Security of any series or portions thereof selected for redemption, in whole or in part, except the unredeemed portion of any such Security being redeemed in part; nor (iii) register the transfer of or exchange of a Security of any series between the applicable record date and the next succeeding Interest Payment Date.

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

9. 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 of a particular series 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.

10. Amendments, Supplements and Waivers.

The Indenture also contains provisions permitting the Holders of a majority 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. 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.

11. Defaults and Remedies. If an Event of Default with respect to the securities of a series issued pursuant to the Sixth Supplemental Indenture occurs and is continuing, the Trustee or the holders of at least 25% in aggregate principal amount of the Securities of such series 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, 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 will 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
