Re. Extension of Outside Date

Dear ▇▇. ▇▇▇▇▇:

1. Reference is made to the Master Purchase Agreement dated as of July 26, 2015 by and between Allergan plc (“Allergan”) and Teva Pharmaceutical Industries Ltd.

Capitalized terms used in this letter agreement (this “Letter”) and not defined herein are used with the meaning so defined in the Agreement.

2. Pursuant to Section 11.1(b) of the Agreement, either Party may extend the Outside Date to October 26, 2016 by delivering notice to the other Party within three business days immediately prior to July 26, 2016 if the conditions set forth in Section 10.1(b) have not been satisfied or waived but all other conditions to the Closing have been satisfied or waived (other than those conditions that by their nature are to be satisfied at the Closing). The Parties hereby agree (1) to waive the notice requirement in Section 11.1(b) of the Agreement, (2) to extend the Outside Date to October 26, 2016 effective immediately, and (3) neither Party has waived any other condition to extending the Outside Date set forth in Section 11.1(b) of the Agreement.

Any signature page hereto delivered by facsimile machine or by e-mail (including in portable document format (pdf), as a joint photographic experts group (jpg) file, or otherwise) shall be binding to the same extent as an original signature page, with regard to any agreement subject to the terms hereof or any amendment thereto and may be used in lieu of the original signatures for all purposes. Any party that delivers such a signature page agrees to later deliver an original counterpart to any party that requests it.
