("Bloomin' Brands") which information is non-public, confidential or proprietary in nature; (ii) you will not issue, publish or otherwise make any public statement or any other form of communication relating to Bloomin' Brands or the Proxy Solicitation without the prior approval of JANA; and (iii) you will not agree to serve, or agree to be nominated to stand for election by Bloomin' Brands or any other stockholder of Bloomin' Brands (other than JANA), as a director of Bloomin' Brands without the prior approval of JANA.

3. You, your family members or your affiliates may invest in shares of common stock of Bloomin' Brands ("Shares").
