Base Indenture and First Supplemental Indenture

On December 10, 2014, Medtronic, Inc., a Minnesota corporation (the “Company”), entered into an indenture (the “Base Indenture”) between the Company and Wells Fargo, National Association, as trustee (the “Trustee”), as supplemented by a first supplemental indenture, dated December 10, 2014 (the “First Supplemental Indenture” and, together with the Base Indenture, the “Indenture”) between the Company and the Trustee. Pursuant to the Indenture, on December 10, 2014, the Company issued $500,000,000 aggregate principal amount of its floating rate senior notes due 2020 (“the floating rate senior notes”), $1,000,000,000 aggregate principal amount of its 1.500% senior notes due 2018 (the “2018 notes”), $2,500,000,000 aggregate principal amount of its 2.500% senior notes due 2020 (the “2020 notes”), $2,500,000,000 aggregate principal amount of its 3.150% senior notes due 2022 (the “2022 notes”), $4,000,000,000 aggregate principal amount of its 3.500% senior notes due 2025 (the “2025 notes”), $2,500,000,000 aggregate principal amount of its 4.375% senior notes due 2035 (the “2035 notes”) and $4,000,000,000 aggregate principal amount of its 4.625% senior notes due 2045 (the “2045 notes” and, together with the 2018 notes, the 2020 notes, the 2022 notes, the 2025 notes and the 2035 notes, the “fixed rate notes” and, together with the floating rate notes, the “Notes”). The Notes were sold pursuant to a purchase agreement, dated December 1, 2014, by and among the Company and Merrill Lynch, Pierce, Fenner & Smith Incorporated, Deutsche Bank Securities Inc. and J.P. Morgan Securities LLC, as representatives (the “Representatives”) of the several initial purchasers listed in Schedule 1 thereto (the “Initial Purchasers”). The Company intends to use the proceeds from the offering of the Notes, together with borrowings under its existing term loan agreement, if any, to fund the cash consideration for the previously announced pending acquisition (the “Covidien Acquisition”) of Covidien plc (“Covidien”) and certain transaction and financing expenses, and for working capital and general corporate purposes, which may include repayment of indebtedness from time to time.

The Notes were not registered under the Securities Act of 1933, as amended (the “Securities Act”), or the securities laws of any other jurisdiction. The Notes were offered only to qualified institutional buyers in accordance with Rule 144A under the Securities Act and outside the United States in accordance with Regulation S under the Securities Act.

The Notes are senior unsecured obligations of the Company and rank equally in right of payment with all of the Company’s existing and future senior unsecured indebtedness. Prior to the consummation of the Covidien Acquisition, the Notes will not be guaranteed. Pursuant to the Indenture, by no later than the end of the third business day following the closing of the Covidien Acquisition, the Company shall cause Medtronic Holdings Limited, a private limited company incorporated in Ireland that will be re-registered as a public limited company and renamed Medtronic plc (“New Medtronic”), and Medtronic Global Holdings, SCA, a partnership limited by shares (sociéte en commandite par actions) incorporated under the laws of the Grand-Duchy of Luxembourg (“Medtronic Luxco”), to enter into a supplemental indenture to the Indenture, pursuant to which such parties will each fully and unconditionally guarantee the Company’s obligations under the Notes and the Indenture. New Medtronic will become the Company’s ultimate parent upon closing of the Covidien Acquisition and Medtronic Luxco is expected to become the Company’s intermediate parent promptly following the closing of the Covidien

Acquisition. The guarantees will be senior unsecured obligations of each guarantor and will rank equally in right of payment with all of the existing and future senior unsecured indebtedness of New Medtronic and Medtronic Luxco, respectively.

The Notes are divided in seven tranches with varying interest rates and maturities, with interest payable on each series of fixed rate notes on March 15 and September 15 of each year, commencing March 15, 2015. The floating rate notes bear interest at a floating rate equal to three-month LIBOR plus 0.800% per annum, with interest payable on March 15, June 15, September 15 and December 15 of each year, commencing March 15, 2015. The Notes will mature on March 15 of their respective year of maturity. The Company may redeem some or all of the fixed rate notes, in whole or in part, at any time and from time to time prior to maturity, at the applicable redemption price set forth in the Notes of such series.

In the event that the Company does not consummate the Covidien Acquisition on or prior to March 15, 2015 (as such date may be extended by the Company on one or more occasions to a date no later than June 15, 2015, subject to certain conditions), or if the agreement relating to the Covidien Acquisition is terminated at any time prior thereto, the Company will be required to redeem, pursuant to a special mandatory redemption, all of the floating rate notes, the 2020 notes, the 2022 notes, the 2025 notes and the 2035 notes at 101% of the aggregate principal amount of such notes, plus accrued and unpaid interest up to, but not including, the redemption date.

The Indenture contains covenants that limit the Company’s and its restricted subsidiaries’ ability to, among other things, incur secured debt and enter into sale and leaseback transactions. These covenants are subject to a number of important exceptions and qualifications, as described in the Indenture.

The Indenture provides for customary events of default (subject in certain cases to customary grace and cure periods), which include non-payment, failure to comply with the special mandatory redemption provisions, breach of other covenants in the Indenture, failure by either New Medtronic or Medtronic Luxco to provide a guarantee as required under the Indenture, unenforceability of a guarantee and certain events of bankruptcy, insolvency or reorganization.

The foregoing does not constitute a complete summary of the terms of the Base Indenture and the First Supplemental Indenture. The description of the terms of the Base Indenture and the First Supplemental Indenture is qualified in its entirety by reference to the Base Indenture and the First Supplemental Indenture, which are filed herewith as Exhibit 4.1 and Exhibit 4.2, respectively.

Registration Rights Agreement

In connection with the issuance of the Notes, on December 10, 2014, the Company entered into a registration rights agreement (the “Registration Rights Agreement”) between the Company and the Representatives that provides holders of the Notes certain rights relating to registration of the Notes under the Securities Act. Pursuant to the Registration Rights Agreement, by no later than the end of the third business day following the closing of the

3

Covidien Acquisition, each of New Medtronic and Medtronic Luxco will enter into a joinder agreement (the “Joinder”) under which each of New Medtronic and Medtronic Luxco will become a party to the Registration Rights Agreement. Pursuant to the Registration Rights Agreement, the Company, and following the closing of the Covidien Acquisition and entry into the Joinder, New Medtronic and Medtronic Luxco, have agreed to use their commercially reasonable efforts to (1) file a registration statement on an appropriate registration form with respect to a registered offer to exchange the Notes for new notes (the “exchange notes”) that, following the closing of the Covidien Acquisition, are guaranteed by New Medtronic and Medtronic Luxco, with terms substantially identical in all material respects to the Notes (except that the exchange notes will not contain terms with respect to transfer restrictions, any increase in annual interest rate for failure to comply with the registration rights agreement or the special mandatory redemption), (2) cause the exchange offer registration statement to be declared effective under the Securities Act by the earlier of (i) the date that is 270 days after the closing of the Covidien Acquisition and (ii) December 10, 2015 and (3) complete the exchange offer within 45 days of the effectiveness of the exchange offer registration statement. The exchange offer will remain open for at least 20 business days (or longer if required by applicable law) after the date the Company mails notice of the exchange offer to holders of the Notes.

If the Company determines that a registered exchange offer is not available or may not be completed as soon as practicable after the last date for acceptance of the notes for exchange because it would violate any applicable law or applicable interpretations of the staff of the Securities and Exchange Commission or, if for any reason the exchange offer is not completed by the exchange offer deadline, or, if in certain circumstances, any Initial Purchaser so requests in writing in connection with any offer or sale of Notes, representing that it holds Notes that were ineligible to be exchanged in the exchange offer, the Company and, following the closing of the Covidien Acquisition and the effectiveness of New Medtronic and Medtronic Luxco’s respective guarantees of the Notes, each of New Medtronic and Medtronic Luxco will use commercially reasonable efforts to file and to have become effective a shelf registration statement relating to resales of such Notes and to keep that shelf registration continuously effective for a period that will terminate when all such Notes cease to be Registrable Securities (as defined in the Registration Rights Agreement)

If a Registration Default (as defined in the Registration Rights Agreement) occurs with respect to notes of a particular series that are Registrable Securities, then additional interest shall accrue on the principal amount of the notes of such series that are Registrable Securities at a rate of 0.25% per annum for the first 90-day period beginning on the day immediately following such Registration Default (which rate will be increased by an additional 0.25% and will increase by an additional 0.25% per annum for each subsequent 90-day period that such additional interest continues to accrue, provided that the rate at which such additional interest accrues may in no event exceed 1.00% per annum).

The foregoing does not constitute a complete summary of the terms of the Registration Rights Agreement. The description of the terms of the Registration Rights Agreement is qualified in its entirety by reference to the Registration Rights Agreement, which is filed herewith as Exhibit 4.10.
