The Company will request the principal Euro-Zone office of each of these banks to provide to the Paying Agent and Calculation Agent a quotation in writing of its rate. If at least two quotations are provided in writing, EURIBOR for such EURIBOR Interest Determination Date will be the arithmetic mean (rounded upwards in accordance with Section 1.2(3)(d) hereof) of such quotations, calculated by the Calculation Agent. The Company will ensure that the Calculation Agent is provided with appropriate contact details of the relevant personnel at each of the reference banks that the Calculation Agent will be requested to contact to provide such quotation of its rates.

(iv)

If fewer than three banks selected by the Company are quoting as described in clause (iii) above, EURIBOR shall be the EURIBOR then in effect on such EURIBOR Interest Determination Date.

(c) Upon the request of any Holder to the Calculation Agent, the Calculation Agent will provide the interest rate then in effect on the Floating Rate Notes and, if determined, the interest rate that will become effective on the next Floating Rate Interest Reset Date.

(d) All percentages resulting from any calculation with respect to the Floating Rate Notes will be rounded upward or downward, as appropriate, to the next higher or lower one hundred thousandth of a percentage point (e.g., 9.876541% (or .09876541) being rounded down to 9.87654% (or .0987654) and 9.876545% (or .09876545) being rounded up to 9.87655% (or .0987655)). All amounts used in or resulting from any calculation with respect to the Floating Rate Notes will be rounded upward or downward, as appropriate, to the nearest cent, in the case of euro amounts or U.S. dollars, or to the nearest corresponding hundredth of a unit, in the case of a currency other than euro amounts or U.S. dollars, with one-half cent or one-half of a corresponding hundredth of a unit or more being rounded upward.

(4) The rate at which the 2026 Notes shall bear interest shall be 1.400% per annum, the rate at which the 2029 Notes shall bear interest shall be 1.950% per annum, and the rate at which the 2037 Notes shall bear interest shall be 2.875% per annum.

The regular record date shall be January 8, in the case of the 2026 Notes, and July 9, in the case of the 2029 Notes and the 2037 Notes, in each case, whether or not a Business Day, immediately preceding the related Interest Payment Date.

In such circumstances, the amount payable on any date in euro shall be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second Business Day prior to the relevant payment date or, in the event the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the most recent U.S. dollar/euro exchange rate published in The Wall Street Journal on or prior to the second Business Day prior to the relevant payment date.

(c) The Notes of any series shall also be redeemable, in whole, but not in part, at any time at the Company’s option, at an Optional Redemption Price equal to 100% of the principal amount of the Notes, plus, accrued and unpaid interest and any Additional Amounts thereon, if the Company determines that (A) as a result of any change or amendment to the laws, treaties, regulations or rulings of the United States of America or any political subdivision or taxing authority thereof, which change or amendment is announced and becomes effective on or after July 18, 2017, there is a material probability that the Company has or will become obligated to pay Additional Amounts of such series or (B) on or after July 18, 2017, any change in the official application, enforcement or interpretation of those laws, treaties, regulations or rulings, including a holding by a court of competent jurisdiction in the United States or any other action, taken by any taxing authority or a court of competent jurisdiction in the United States, whether or not such action was taken or made with respect to the Company, results in a material probability that the Company has or will become obligated to pay Additional Amounts on any Notes of such series; provided that the Company determines, in its business judgment, that the obligation to pay such

Additional Amounts cannot be avoided by use of reasonable measures available to the Company, not including substitution of the obligor under such Notes. Prior to the mailing of any notice of such a redemption, the Company shall deliver to the Trustee (1) an Officer’s Certificate stating that the Company is entitled to effect such a redemption and setting forth a statement of facts showing that the conditions precedent to the right of the Company to so redeem have occurred and (2) an Opinion of Counsel to such effect based on such statement of facts.

(d) 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.

(e) 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. No later than 10:00 a.m. London time on the Business Day prior to the Optional Redemption Date for any Notes to be redeemed, the Company shall deposit with the Trustee or Paying Agent, funds sufficient to pay the Optional Redemption Price of such Notes on the Optional Redemption Date, and (except if the date fixed for redemption shall be an Interest Payment Date) accrued and unpaid interest and Additional Amounts, if any. If less than all of the Notes of any series are to be redeemed, the Notes to be redeemed shall be selected, in the case of global securities, in accordance with applicable Depositary procedures and, in the case of definitive securities in a manner the trustee deems fair and appropriate, unless otherwise required by law or applicable stock exchange requirements.

(f) Notice of any optional redemption shall be transmitted at least 15 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 (b), 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. Notice of redemption having been given as provided in the Indenture, the Notes called for redemption shall, on the Optional Redemption Date, become due and payable at the Optional Redemption Price, plus accrued and unpaid interest and Additional Amounts, if any, to, but excluding, the Optional Redemption Date.

Section 1.3A Special Mandatory Redemption

(a) The provisions of Article III of the Base Indenture, as amended by the provisions of this Supplemental Indenture, shall apply to the Notes with respect to this Section 1.3A.

(i)

the Company does not consummate the Patheon Acquisition on or prior to February 15, 2018; or

(ii)

the Purchase Agreement is terminated any time prior to February 15, 2018 for any reason.

(d) On the Special Mandatory Redemption Date, the Company shall redeem all of the Notes at the redemption price equal to 101% of the aggregate principal amount of the Notes to be redeemed (the “Special Mandatory Redemption Price”), plus, in addition to such Special Mandatory Redemption Price, in each case, accrued and unpaid interest, if any, to, but excluding, the Special Mandatory Redemption Date. Notwithstanding the foregoing, installments of interest whose Stated Maturity is on or prior to the Special Mandatory Redemption Date shall be payable on the applicable Interest Payment Date to the Security 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.

(e) On and after the Special Mandatory Redemption Date for the Notes, interest shall cease to accrue on the Notes unless the Company defaults in the payment of the Special Mandatory Redemption Price and accrued interest, if any. No later than 10:00 a.m. London time on the Business Day before the Special Mandatory Redemption Date for the Notes, the Company shall deposit with the Trustee or Paying Agent, funds sufficient to pay the Special Mandatory Redemption Price of the Notes to be redeemed on the Special Mandatory Redemption Date, and (except if the date fixed for redemption shall be an Interest Payment Date) accrued interest, if any. Notice of redemption shall be mailed, with a copy to the Trustee, no later than five (5) Business Days following the Special Mandatory Redemption Triggering Event, to each Holder of such Notes at its registered address (a “Special Mandatory Redemption Notice”).

(f) The Special Mandatory Redemption Notice shall state the information set forth in, and shall be subject to the terms and conditions of, Section 3.02 of the Base Indenture.

Section 1.4 Additional Covenants.

The following additional covenants shall apply with respect to the Notes so long as any of the Notes remain Outstanding:

(1) Change of Control Triggering Event.

(2) Additional Amounts.

(a) All payments of principal and interest in respect of the Notes shall be made free and clear of, and without deduction or withholding for or on account of any present or future taxes, duties, assessments or other governmental charges of whatsoever nature imposed, levied, collected, withheld or assessed by the United States or any political subdivision or taxing authority of or in the United States, unless such withholding or deduction is required by law.

(b) The Company shall pay to a Holder who is not a United States person additional amounts as may be necessary so that every net payment of the principal of and premium, if any, and interest on the Notes to such Holder, after deduction or withholding for or on account of any present or future tax, assessment or other governmental charge imposed upon such Holder by the United States of America or any taxing authority thereof or therein, shall not be less than the amount provided in the Note to be then due and payable (such amounts, the “Additional Amounts”); provided, however, that the Company shall not be required to make any payment of Additional Amounts for or on account of:

(v)

any tax, assessment or other governmental charge required to be withheld by any paying agent from any payment of principal of or premium, if any, or interest on the Notes of that Holder if such payment can be made without withholding by any other paying agent;

(vi)

any tax, assessment or other governmental charge which would not have been imposed but for the failure of a Holder (or the beneficial owner for whose benefit such Holder holds the Notes), or a fiduciary, settlor, beneficiary of, member or shareholder of, or possessor of power over, the holder or beneficial owner, if that Holder or beneficial owner is an estate, trust, partnership or corporation, or any intermediary through which a beneficial owner holds Notes to comply with certification, information, documentation or other reporting requirements concerning the nationality, residence, identity or connections with the United States of America of the beneficial owner or any Holder (including, but not limited to, the requirement to provide Internal Revenue Service Forms W-8BEN, Forms W-8BEN-E, Forms W-8ECI, or any subsequent versions thereof or successor thereto, and including, without limitation, any documentation requirement under an applicable income tax treaty);

Thermo ▇▇▇▇▇▇ Scientific Inc.

Floating Rate Senior Notes due 2019

This security is one of a duly authorized series of debt securities of Thermo ▇▇▇▇▇▇ 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., as trustee (the “Trustee”), as supplemented by the Sixteenth Supplemental Indenture, dated as of July 24, 2017 (the “Supplemental Indenture”), between the Company and the Trustee. The Securities are subject to a Paying Agency Agreement, dated as of July 24, 2017 (the “Paying Agency Agreement”), between the Company and The Bank of New York Mellon, London Branch, as paying agent (the “Paying Agent”), and a Calculation Agency Agreement, dated as of July 24, 2017 (the “Calculation Agency Agreement”), between the Company and the Bank of New York Mellon London Branch, as calculation agent (the “Calculation 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 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 Securities will bear interest from July 24, 2017 or from the immediately preceding Interest Payment Date to which interest has been paid. Interest on the Securities shall be payable quarterly in arrears on January 24, April 24, July 24 and October 24 of each year (each, a “Interest Payment Date”), commencing on October 24, 2017; provided, that, if any Interest Payment Date would be a day that is not a Business Day, such Interest Payment Date shall be the next succeeding day that is a Business Day (and no additional interest will accrue or otherwise accumulate on the amount payable for the period from and after such Interest Payment Date); except that if such next succeeding Business Day falls in the next succeeding calendar month, such Interest Payment Date shall be the immediately preceding Business Day. The Securities shall bear interest at a rate equivalent to the 3-month EURIBOR (the “Base Rate”) plus 0.230% per annum, as calculated by the Calculation Agent; provided, however, that the minimum interest rate shall be zero. The interest rate on the Securities will be reset quarterly on January 24, April 24, July 24 and October 24 of each year (each, an “Interest Reset Date”), commencing on October 24, 2017; provided, that, if any Interest Reset Date would be a day that is not a Business Day, such Interest Reset Date shall be the next succeeding day that is a Business Day, except that if such next succeeding Business Day falls in the next succeeding calendar month, such Interest Reset Date shall be the immediately preceding Business Day. The initial Base Rate for the Securities in effect from July 24, 2017 to, but excluding, the first Interest Reset Date will be the 3-month EURIBOR in effect on July 20, 2017. The interest rate on the Securities will be determined on the second TARGET2 Business Day preceding the applicable Floating Rate Interest Reset Date (a “EURIBOR Interest Determination Date”). Interest on the Floating Rate Notes will be computed on the basis of a 360-day year and the actual number of days in the period for which interest is being calculated.

A-4

The Base Rate that takes effect on any Interest Reset Date shall be equal to the interest rate for deposits in euro designated as “EURIBOR” and sponsored jointly by the European Banking Federation and ACI—the Financial Market Association (or any company established by the joint sponsors for purposes of compiling and publishing that rate) on each EURIBOR Interest Determination Date, and will be determined by the Calculation Agent in accordance with the following provisions:

ii.

If the rate described in clause (i) above does not appear on Reuters Page ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇ will be determined on the basis of the rates, at approximately 11:00 A.M., Brussels time, on the relevant EURIBOR Interest Determination Date, at which deposits of the following kind are offered to prime banks in the Euro-Zone interbank market by the principal Euro-Zone office of each of four major banks in that market selected by the Company: euro deposits having a maturity of three months beginning on such Interest Reset Date and in a principal amount of not less than €1,000,000 that is representative for a single transaction in such market at such time. The Company will request the principal Euro-Zone office of each of these banks to provide to the Paying Agent and Calculation Agent a quotation in writing of its rate. If at least two quotations are provided in writing, EURIBOR for such EURIBOR Interest Determination Date will be the arithmetic mean (rounded upwards in accordance with Section 1.2(3)(d) of the Supplemental Indenture) of such quotations calculated by the Calculation Agent. The Company will ensure that the Calculation Agent is provided with appropriate contact details of the relevant personnel at each of the reference banks that the Calculation Agent will be requested to contact to provide such quotation of its rates.

iii.

If fewer than two quotations are provided as described in clause (ii) above, EURIBOR for the relevant EURIBOR Interest Determination Date will be the arithmetic mean of the rates for loans of the following kind to leading Euro-Zone banks quoted in writing, at approximately 11:00 A.M., Brussels time, on such EURIBOR Interest Determination Date, by three major banks in the Euro-Zone selected by the Company: loans of euro having a maturity of three months beginning on such Interest Reset Date and in a principal amount of not less than €1,000,000 that is representative for a single transaction in such market at such time.

A-5

iv.

If fewer than three banks selected by the Company are quoting as described in clause (iii) above, EURIBOR shall be the EURIBOR then in effect on such EURIBOR Interest Determination Date.

Upon the request of any Securityholder to the Calculation Agent, the Calculation Agent will provide the interest rate then in effect on the Securities and, if determined, the interest rate that will become effective on the next Interest Reset Date.

All percentages resulting from any calculation with respect to the Securities will be rounded upward or downward, as appropriate, to the next higher or lower one hundred- thousandth of a percentage point (e.g., 9.876541% (or .09876541) being rounded down to 9.87654% (or ..0987654) and 9.876545% (or .09876545) being rounded up to 9.87655% (or 0987655)). All amounts used in or resulting from any calculation with respect to the Securities will be rounded upward or downward, as appropriate, to the nearest cent, in the case of euro amounts or U.S. dollars, or to the nearest corresponding hundredth of a unit, in the case of a currency other than euro amounts or U.S. dollars, with one-half cent or one-half of a corresponding hundredth of a unit or more being rounded upward.

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 an optional redemption or Special Mandatory Redemption or there is a Change of Control Offer, and the Optional Redemption Date, Special Mandatory 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 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, Calculation Agent and Security Registrar. Initially, The Bank of New York Mellon, London Branch, shall act as the Paying Agent and Calculation Agent in accordance with the terms of the Paying Agency Agreement and the Calculation Agency Agreement, respectively, and the Trustee shall act as Security Registrar. Upon prior notice to the Trustee, the Company may change or appoint any Paying Agent, Security Registrar or Calculation Agent without notice to any Securityholder. The Company or any of its Subsidiaries may act in any such capacity.

A-6

shall furnish to any Securityholder upon written request and without charge a copy of the Base Indenture and the Supplemental Indenture. Requests may be made to: Thermo ▇▇▇▇▇▇ Scientific Inc., ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, Attention: ▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇▇.

The Notes are subject to a Paying Agency Agreement, dated as of July 24, 2017 (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.

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 [ ]¹¹. Interest on the Securities shall be computed on the basis of an ACTUAL/ACTUAL (ICMA) (as defined in the rulebook of ICMA) day count convention.
