Credit Agreements

The Acquisition and the Merger

On June 15, 2014, Medtronic, Inc., a Minnesota corporation (“Medtronic”), entered into a Transaction Agreement (the “Transaction Agreement”) by and among Medtronic, Covidien public limited company, an Irish public limited company (“Covidien”), Kalani I Limited, a private limited company organized under the laws of Ireland (“New Medtronic”), Makani II Limited, a private limited company organized under the laws of Ireland and a wholly owned subsidiary of New Medtronic (“IrSub”), Aviation Acquisition Co., Inc., a Minnesota corporation (“U.S. AcquisitionCo”), and Aviation Merger Sub, LLC, a Minnesota limited liability company and a wholly owned subsidiary of U.S. AcquisitionCo (“MergerSub”). Under the terms of the Transaction Agreement, (i) IrSub will acquire Covidien (the “Acquisition”) pursuant to a scheme of arrangement under Section 201, and a capital reduction under Sections 72 and 74, of the Irish Companies Act of 1963 (the “Scheme”) and (ii) MergerSub will merge with and into Medtronic, with Medtronic as the surviving corporation in the merger (“New Medtronic”) (such merger, the “Merger,” and the Merger together with the Acquisition, the “Transactions”). As a result of the Transactions, both Medtronic and Covidien will become wholly owned subsidiaries of New Medtronic.

Bridge Credit Agreement

On June 15, 2014, Medtronic entered into a 364-day senior unsecured bridge credit agreement (the “Bridge Credit Agreement”) among Medtronic, New Medtronic, the lenders from time to time party thereto and Bank of America, N.A., as administrative agent. Under the Bridge Credit Agreement, Bank of America, N.A. has committed to provide Medtronic with unsecured financing in an aggregate principal amount of up to $2,800,000,000. The commitments are intended to be drawn to finance, in part, the cash component of the acquisition consideration and certain transaction expenses to the extent Medtronic does not arrange for alternative financing prior to the consummation of the Transactions. New Medtronic has guaranteed the obligations of Medtronic under the New Bridge Credit Agreement. If Medtronic draws loans under the Bridge Credit Agreement, it intends to refinance any debt incurred thereunder.

Cash Bridge Credit Agreement

Medtronic will require an additional $13,500,000,000 in order to finance the cash component of the acquisition consideration and certain transaction expenses. Medtronic expects to have cash equivalents in such amount available to it by the time of the consummation of the Transactions. In order to backstop the anticipated amount of cash on hand at the consummation of the Transactions, on June 15, 2014, IrSub entered into a 60-day senior unsecured cash bridge credit agreement (the “Cash Bridge Credit Agreement” and together with the Bridge Credit Agreement, the “Credit Agreements”) among IrSub, New Medtronic, the lenders from time to time party thereto and Bank of America as administrative agent. Under the Cash Bridge Credit Agreement, Bank of America, N.A. has committed to provide IrSub with unsecured financing in an aggregate principal amount of up to $13,500,000,000 for a 60-day period. New Medtronic has also guaranteed the obligations of IrSub under the Cash Bridge Credit Agreement and has agreed to cause each of Medtronic and Covidien to provide additional guarantees of such obligations following the consummation of the Transactions. Loans drawn under the Cash Bridge Credit Agreement are expected to be repaid from cash equivalents liquidated by Medtronic.

General

The funding of the loans under each Credit Agreement (the “Closing Date”) is conditioned on, among other things, the consummation of the Transactions and the absence of certain events of defaults described in each Credit Agreement. The commitments under each Credit Agreement automatically terminate on the earliest of (a) the funding and disbursement of the loans to the borrower on the Closing Date, (b) the occurrence of certain mandatory cancellation events or (c) March 15, 2015 (or if all but certain conditions under the Transaction Agreement have been completed, one year after June 15, 2015).

Loans outstanding under each Credit Agreement will bear interest, at the borrower’s option, either (a) at the base rate (defined as the highest of (1) the prime rate of Bank of America, N.A., (2) the federal funds rate plus 0.50% and (3) the applicable interest rate for a eurodollar loan with a one month interest period beginning on such day plus 1.00%) or (b) at the eurodollar rate, plus, in each case, an applicable margin which shall range depending on the debt rating of the borrower and, in the case of the Bridge Credit Agreement, the number of days which the loans remain outstanding from the Closing Date. In addition, the borrower under each Credit Agreement has agreed to pay (a) nonrefundable ticking interest of 0.05% on the amount of the aggregate commitments in effect from June 15, 2014 through the termination of the commitments and (b) in the case of the Bridge Credit Agreement, a non-refundable duration fee of 0.50%, 0.75% and 1.00% on the 90th, 180th and 270th days, respectively, after the Closing Date on the aggregate principal amount of the loans outstanding on such day.

The borrower may voluntarily prepay the loans under each Credit Agreement at any time without premium or penalty. Each Credit Agreement also requires mandatory prepayments with the net cash proceeds of certain asset sales or debt or equity issuances subject to customary exceptions. Each Credit Agreement also contains customary events of default, upon the occurrence of which, and so long as such event of default is continuing, the amounts outstanding will accrue interest at an increased rate and payments of such outstanding amounts could be accelerated by the lenders. In addition, the loan parties under each Credit Agreement will be subject to certain affirmative and negative covenants.

The foregoing description of the terms of the Credit Agreements are only summaries, and do not purport to be complete, and are qualified in their entirety by the complete text of the Credit Agreements, copies of which are filed as Exhibits 10.1 and 10.2 hereto and incorporated herein by reference.

The information set forth under Item 1.01 above regarding the Bridge Credit Agreement is incorporated herein by reference.

Actual results may differ materially from Medtronic’s current expectations depending upon a number of factors affecting New Medtronic’s business, Medtronic’s business, Covidien’s business and risks associated with the proposed transactions. These factors include, among others, the inherent uncertainty associated with financial projections; restructuring in connection with, and successful close of, the Covidien acquisition; subsequent integration of the Covidien acquisition and the ability to recognize the anticipated synergies and benefits of the Covidien acquisition; the risk that the required regulatory approvals for the proposed transactions are not obtained, are delayed or are subject to conditions that are not anticipated; the anticipated size of the markets and continued demand for Medtronic’s and Covidien’s products; the impact of competitive products and pricing; access to available financing (including financing for the acquisition or refinancing of Medtronic or Covidien debt) on a timely basis and on reasonable terms; the risks of fluctuations in foreign currency exchange rates; the risks and uncertainties normally incident to the medical device industry, including competition in the medical device industry; product liability claims; the difficulty of predicting the timing or outcome of pending or future litigation or government investigations; variability of trade buying patterns; the timing and success of product launches; the difficulty of predicting the timing or outcome of product development efforts and regulatory agency approvals or actions, if any; potential for adverse pricing movement; costs and efforts to defend or

enforce intellectual property rights; difficulties or delays in manufacturing; reduction or interruption in supply; product quality problems; the availability and pricing of third party sourced products and materials; risks associated with self-insurance and commercial insurance; successful compliance with governmental regulations applicable to New Medtronic’s, Medtronic’s and Covidien’s facilities, products and/or businesses; changes in the laws and regulations, affecting among other things, pricing and reimbursement of pharmaceutical products; health care policy changes; risks associated with international operations; changes in tax laws or interpretations that could increase New Medtronic’s or Medtronic’s consolidated tax liabilities, including, if the transaction is consummated, changes in tax laws that would result in New Medtronic being treated as a domestic corporation for United States federal tax purposes; the loss of key senior management or scientific staff; and such other risks and uncertainties detailed in Medtronic’s periodic public filings with the Securities and Exchange Commission, including but not limited to Medtronic’s Annual Report on Form 10-K for the fiscal year ended April 26, 2013 and from time to time in Medtronic’s other investor communications.
