(Informal English Translation)

To:

Mylan N.V. (the “Offeror”)

Via: Israel Brokerage & Investments I.B.I Ltd.

Re: Ordinary Shares of Perrigo Company plc (the “Company”)

I refer to the Offer to Exchange dated September 14, 2015, whereby the Offeror offered to purchase Ordinary Shares, par value € 0.001 each, of the Company, as detailed therein (the “Offer to Exchange” and the “Tender Offer”, respectively).

Whereas we have received acceptance notices from holders with respect to an aggregate amount of                  Ordinary Shares par value € 0.001 of the Company (the “Acceptance Shares”), now therefore, we hereby submit an acceptance notice of a TASE Member with respect to such Acceptance Shares, and an undertaking to transfer such shares to the Offeror.

We hereby declare and undertake that the Acceptance Shares are free and clear of any lien, attachment, debt, pledge or any third party right on the date of giving this notice of acceptance, and that these Acceptance Shares will be in such condition on the date of their transfer to the name of the Offeror as is required by the Offer to Exchange.

If the Tender Offer will be accepted by the Offeror, please transfer the consideration for such Acceptance Shares to our account at the TASE Clearing House.

We are aware that a condition precedent to the purchase of the Acceptance Shares by the Offeror and for the payment of the related consideration in accordance with the Offer to Exchange, is the accuracy of this declaration, on which the Offeror relies in its purchase.
