basis into shares of Atlas Common Stock, and the terms and conditions that are in effect immediately prior to the Merger under each outstanding Award assumed by Atlas shall continue in full force and effect after the Merger, including the vesting
schedule and applicable issuance dates, the per share exercise price, the expiration date and other applicable termination provisions, except that the shares of Company Class A Common Stock issuable under each such Award shall be shares of
Atlas Common Stock. The adoption of the Merger by the requisite vote of the shareholders of the Company shall also constitute approval, without further action by holders of shares of Company Class A Common Stock of any amendments to the Equity
Plans necessary, appropriate or advisable to authorize (i) the assumption by Atlas of the Equity Plans (including any existing share reserves), and the outstanding Awards under such plans, (ii) the future issuance of shares of Atlas Common
Stock in lieu of shares of Company Class A Common Stock under each of the Equity Plans, and (iii) Atlas’ ability to issue Awards under the Equity Plans to the eligible participants in Equity Plans after the Effective Time.
