Letter Amendment No. 1 dated as of September 1, 2016 to the Multi-Year Senior Unsecured Credit Agreement, dated as of March 10, 2016, among Tyco International Holding S. r.l., each of the initial lenders named therein, Citibank, N.A., as administrative agent, and Citigroup Global Markets Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Barclays Bank plc, Wells Fargo Securities, LLC and JPMorgan Chase Bank, N.A. as joint lead arrangers and joint bookrunners

To the banks, financial institutions and other institutional lenders (collectively, the “Lenders”) parties to the Credit Agreement referred to below and to Citibank, N.A., as agent (the “Administrative Agent”) for the Lenders

Ladies and Gentlemen:

We refer to the Multi-Year Senior Unsecured Credit Agreement dated as of March 10, 2016 (the “Credit Agreement”) among the undersigned and you. Capitalized terms not otherwise defined in this Letter Amendment have the same meanings as specified in the Credit Agreement.

It is hereby agreed by you and us as follows:

The Credit Agreement is, effective as of the date of this Letter Amendment, hereby amended as follows:

(a)Section 5.01(a) is amended by adding to the end thereof a proviso to read as follows:

provided, that (i) the fiscal year of the Borrower for 2016 shall be deemed to end on September 2, 2016 (and the audited financial statements for the fiscal year ended on such date shall consist of 11 months) and (ii) the fiscal year of the Borrower for 2017 and subsequent years shall end on September 30 of such year (and the audited financial statements for the fiscal year ending on September 30, 2017 shall consist of 13 months), it being understood that, as a result of the period changes set forth in this proviso, the previous fiscal year’s figures set forth in comparative form in any affected annual financial statements may reflect a fiscal year with a different number of months.

(b)Section 5.01(b) is amended by adding to the end thereof a proviso to read as follows:

provided, that (i) the fiscal quarter of the Borrower ending December 31, 2016 shall be deemed to begin on September 2, 2016 (and the financial statements for such fiscal quarter shall consist of four months), it being understood that, as a result of the period change set forth in this proviso, the figures set forth in comparative form for the applicable prior periods in the financial statements for such fiscal quarter, or in future quarterly financial statements containing comparative figures covering such fiscal quarter, may reflect a fiscal quarter with a different number of months; and (ii) the financial statements for the fiscal quarter ending December 31, 2016 shall be accompanied by a schedule, certified by the chief financial officer of the chief accounting officer of the Borrower or a Designated Officer, setting forth

the statement of operations, shareholders’ equity and cash flows for the Borrower for the period from September 2, 2016 to September 30, 2016. For the avoidance of doubt, the fiscal quarter of the Borrower deemed ended on September 2, 2016 shall consist of two months.

This Letter Amendment shall become effective as of the date first above written when, and only when, on or before September 1, 2016, the Administrative Agent shall have received counterparts of this Letter Amendment executed by the undersigned and the Required Lenders. This Letter Amendment is a Loan Document and is subject to the provisions of Section 9.02 of the Credit Agreement.

On and after the effectiveness of this Letter Amendment, each reference in the Credit Agreement to “this Agreement”, “hereunder”, “hereof” or words of like import referring to the Credit Agreement, and each reference in the Notes and each of the other Loan Documents to “the Credit Agreement”, “thereunder”, “thereof” or words of like import referring to the Credit Agreement, shall mean and be a reference to the Credit Agreement, as amended by this Letter Amendment.

The Credit Agreement, the Notes and each of the other Loan Documents, as specifically amended by this Letter Amendment, are and shall continue to be in full force and effect and are hereby in all respects ratified and confirmed. The execution, delivery and effectiveness of this Letter Amendment shall not, except as expressly provided herein, operate as a waiver of any right, power or remedy of any Lender or the Administrative Agent under any of the Loan Documents, nor constitute a waiver of any provision of any of the Loan Documents.

If you agree to the terms and provisions hereof, please evidence such agreement by executing and returning at least two counterparts of this Letter Amendment to Frank Oliver, Shearman & Sterling LLP, 599 Lexington Avenue, New York, New York 10022, ***@***.

This Letter Amendment may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Letter Amendment by telecopier shall be effective as delivery of a manually executed counterpart of this Letter Amendment.

This Letter Amendment shall be governed by, and construed in accordance with, the laws of the State of New York.

Very truly yours,

TYCO INTERNATIONAL HOLDING S.ÀR.L.
