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

On July 28, 2016, Marketo, Inc. (“Marketo”) held a special meeting of stockholders (the “Special Meeting”) at Marketo’s principal executive offices in San Mateo, CA.

As of the record date, June 28, 2016, there were 45,027,099 shares of common stock of Marketo eligible to be voted at the Special Meeting.  At the Special Meeting, 37,139,769 shares, or approximately 82% of all outstanding shares of common stock, were present either in person or by proxy.  Two matters were voted upon at the special meeting, with the Board of Directors of Marketo recommending a vote “FOR” in connection with each of the proposals voted upon, as further described in the definitive proxy statement filed with the Securities and Exchange Commission on June 29, 2016 (the “Definitive Proxy Statement”).

Proposal No. 1 (the “Merger Proposal”) was to consider and vote on the proposal to adopt the Agreement and Plan of Merger, dated as of May 27, 2016 (the “Merger Agreement”) by and among Marketo, Milestone Holdco, LLC (“Parent”), and Milestone Merger Sub, Inc. (“Merger Sub”). Parent and Merger Sub are entities that are affiliated with Vista Equity Partners Management, LLC, a leading private equity firm focused on investments in software, data and technology-enabled companies. Pursuant to the terms of the Merger Agreement, Merger Sub will merge with and into Marketo, with Marketo continuing as the surviving corporation and a wholly owned direct subsidiary of Parent (the “Merger”).

Proposal No. 2 (the “Adjournment Proposal”) was to consider and vote on any proposal to adjourn the Special Meeting to a later date or dates if necessary or appropriate to solicit additional proxies if there were insufficient votes to adopt the Merger Agreement at the time of the Special Meeting. Since there were sufficient votes cast at the Special Meeting to adopt the Merger Agreement, a second proposal to adjourn the Special Meeting, if needed or appropriate, to solicit additional proxies was rendered moot.

The Merger Proposal and Adjournment Proposal were approved.  The table below shows the final voting results from the Special Meeting.
