Update on Allergan Transaction

Meetings held with both Allergan and Valeant shareholders

New York, Boston, Baltimore, Los Angeles, San Francisco, Vancouver, South Florida

Transaction feedback has been overwhelmingly positive

Additional meetings scheduled or will be scheduled

Common Themes from Allergan shareholders

Combination makes tremendous strategic sense and will create significant long-term value for both sets of shareholders

Allergan R&D spend is too high and SG&A cost structure is excessive

Allergan team should enter discussions with the Valeant team in parallel with their outreach to third parties

14

Update on Allergan Transaction

Expect to hear from Allergan Board / Management within next few weeks

We are ready to negotiate

In the interim, together with Pershing Square:

We are requesting a shareholder list and other information from Allergan, which Allergan is required to provide under Delaware law

We will commence a shareholder referendum that will determine whether shareholders are supportive of Allergan’s Board engaging in discussions with

Valeant in parallel with other efforts underway

At the appropriate time, we will pursue holding a special meeting to remove some / all of the Allergan Board members

We are strongly committed to this transaction

This combination will create an unrivaled platform for growth and value creation for both sets of shareholders

We will continue to execute our strategy of delivering strong organic growth coupled with growth through business development

While speed ensures the best possible value for Allergan shareholders, we are committed to completing this transaction
