Item 5.07 Submission of Matters to a Vote of Security Holders.

On December 18, 2014, Trulia, Inc. (“Trulia”) held a special meeting of stockholders (the “Special Meeting”). At the Special Meeting, Trulia’s stockholders adopted the previously announced Agreement and Plan of Merger, dated as of July 28, 2014 (the “Merger Agreement”), by and among Zillow, Inc. (“Zillow”) Zebra Holdco, Inc. (“Holdco”), and Trulia. Following the consummation of the transactions contemplated by the Merger Agreement, Zillow and Trulia will become wholly owned subsidiaries of Holdco. The stockholders of Trulia also approved the authorization of nonvoting Class C capital stock in Holdco’s amended and restated articles of incorporation (“Class C Authorization”). Stockholder action on a third proposal, to approve the adjournment of the special meeting if necessary or appropriate to solicit additional proxies in favor of proposal 1 or proposal 2, was not required and no vote was taken on that proposal.
