3. When will the restriction on Employee Stock Purchase Plan (ESPP) shares be lifted?

The following ESPP restrictions will be waived on the acquisition transaction date:

• Shares purchased within 12 months prior to the acquisition date: The requirement that you hold the stock for at least 12 months will be waived.

• Shares purchased more than 12 months, but less than 24 months prior to the acquisition transaction date: The requirement that you hold the stock for at least 24 months before you transfer stock will be waived.

4. Why won’t the restriction on ESPP shares be lifted immediately?

The purpose of removing the ESPP restrictions is to allow employees to sell shares to cover any tax obligation that results after the transaction closes.

5. Will new restrictions be placed on ESPP shares I have already purchased at the time of the acquisition transaction?

There will be no new restrictions on the stock as of the acquisition transaction.

6. Where can I find more information on my historical ESPP purchases and/or dividend reinvestments?

By late October, participants in the ESPP program will receive two statements from Wells Fargo that include book entry details on shares purchased, the cost basis for those shares and dividend reinvestment information from 2000 onward.

You can also view your ESPP share information by logging into your Wells Fargo account at: www.shareowneronline.com.

If you are looking for Dividend Reinvestment information prior to 2000, you can view the Dividend History and DRIP-Dividend Payment History found on medtronic.com under Investors – Stock Information.

7. How do I find more information on my stock awards?

To access information on your stock awards:

• Login to the Schwab Equity Award Center website at www.schwab.com/medtronic.

• Call 800.654.2593 (U.S. and Puerto Rico employees) or lookup your country code and dialing instructions (non-U.S. employees).

8. I would like to donate Medtronic stock to a charity before the acquisition transaction occurs. Will Medtronic match my contributions?

Yes, through the Matching Grants program, Medtronic Philanthropy matches offline stock donations, including U.S. employee donations made to Donor-Advised Funds*. You will need to make the stock donation entirely on your own and upload proof of donation to Mission in Motion and record it as an offline donation.

For any questions related to the Matching Grants program, please email: medtronic-support@yourcause.com.

*A Donor-Advised Fund is a charitable giving account that is provided by community foundations and by for profit financial services companies. Donor-Advised Funds that are eligible for the Matching Gifts program are listed on the Mission in Motion website.

9. I am a U.S. or Puerto Rico taxpayer considering donating or gifting Medtronic stock. How will this affect my tax liability?

If you are considering a donation or gift to charity or, possibly, family members, you should be aware that the timing of your donation or gift is important. The more certain it is, at the time of your donation or gift, that the transaction will ultimately be completed, the greater the risk that you will be taxed on the transaction even though you no longer own the stock at the time the transaction is completed. On the other hand, you should keep in mind that the completion of the transaction is subject to various conditions and that once you make the gift, you will not be able to take back the Medtronic stock even if the transaction is never completed. In any case, whether you donate your stock to charity or make a gift of your stock to an individual, you will be subject to tax on your compensation-related income (that is, the discount to the purchase price you paid for your shares) as a result of your donation or gift. In light of these and other potential issues relevant to a donation or gift of the stock, we recommend you consult your financial and/or legal advisor as soon as possible to receive guidance about the rules for donating in light of your particular circumstances.

9. Can I share Medtronic communications about tax implications of the Covidien acquisition with my financial planner?

Yes. This communication, along with the communication to employees titled Tax Implications of the Covidien Acquisition to Medtronic Employees dated June 27, 2014, can be shared with your financial planner.

U.S. Employees Only (as applicable):

10. What is the difference between the Employee Stock Ownership Plan (ESOP) and the Employee Stock Purchase Plan (ESPP)?

Employees at Medtronic prior to May 1, 2005, received Medtronic stock contributions – the former plan was the Medtronic, Inc. Employee Stock Ownership and Supplemental Retirement Plan – those shares may still be part of an employee’s 401(k) account.

The Employee Stock Purchase Plan allows you to purchase Medtronic stock each calendar quarter at a discount by contributing 2% to 10% of your eligible earnings on an after-tax basis. Each purchase period, you may elect to purchase Medtronic stock at a discounted price which is 85% of the fair market value of Medtronic stock on the last day of the quarterly purchase period.

11. Why is the 401(k) plan not impacted by the acquisition transaction?

The 401(k) plan is a qualified retirement plan and Medtronic shares owned through qualified plans are not subject to capital gains taxes. Plan distributions are taxed at ordinary income rates, not capital gains rates.

12. How are ESOP shares in the Medtronic, Inc. 401(k) Plan impacted by the acquisition transaction?

The tax basis on ESOP shares in the Medtronic, Inc. 401(k) Plan will be maintained; therefore, the potential tax benefit of ESOP shares is not lost with the Covidien acquisition. ESOP shares in the 401(k) Plan are specifically identified in the 401(k) Plan and will continue to be maintained as a separate account in the 401(k) Plan.

13. What impact will the acquisition have on the Medtronic Retirement Plan (MRP) and Medtronic sponsored retiree health care?

There is no Medtronic stock component to the Medtronic Retirement Plan (MRP), so there is no impact to that plan. The acquisition of Covidien will not change our commitment to pension obligations.

While health care costs continue to rise at an unsustainable rate, we remain committed to helping retirees access quality medical coverage that is viable for the company and affordable for retirees. As the health care landscape continues to evolve, we will explore all options available to meet that commitment. The acquisition of Covidien will not change our commitment.
