constitutes, or would reasonably be expected to lead to, an Alternative Proposal, (b) participate in any discussions or negotiations regarding, or that would reasonably be expected to lead to any Alternative Proposal (other than to inform a

the “Restricted Activities”). 
 Section 2.2    Notification. Stockholder (in its capacity
as a stockholder of Earthstone) shall, and shall cause the Stockholder Representatives to, immediately cease and terminate any and all existing activities, discussions or negotiations with any Person with respect to an Alternative

of execution of judgment, execution of judgment or otherwise) and (c) to the fullest extent permitted by applicable law, any claim that (i) the suit, action or proceeding in such court is brought in an inconvenient forum, (ii) the venue of such

or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.
