ITEM 8.01 Other Events.

On July 12, 2016, a purported stockholder class action lawsuit captioned Rosati v. Marketo, Inc. et al., Case No. 3:16-cv-3907 (“Federal Complaint”), was filed in the United States District Court, Northern District of California against Marketo and its directors.  The lawsuit alleges, generally, that Marketo and its directors violated Section 14(a) of the Securities Exchange Act of 1934 and Rule 14a-9 by issuing a false and misleading Proxy Statement.  The lawsuit also alleges that Marketo’s directors breached their fiduciary duties to Marketo stockholders by failing to disclose all material facts concerning the proposed Merger to stockholders and seeking to sell Marketo through an allegedly defective process, for an unfair price, and on unfair terms. The lawsuit seeks, among other things, equitable relief that would enjoin the consummation of the proposed Merger, rescissory damages to the extent the Merger is consummated, and attorneys’ fees and costs.

On July 21, 2016, the plaintiffs filed a request for a Temporary Restraining Order seeking to enjoin the shareholder vote. Marketo intends to vigorously oppose the request.

The allegations of the Federal Complaint are substantially similar to those alleged in the previously disclosed lawsuit captioned Porwal v. Marketo, Inc. et al., Case No. 16CIV00265 filed in Superior Court of the State of California, County of San Mateo, which was disclosed in the Current Report on Form 8-K filed by Marketo, Inc. under Item 8.01 on July 11, 2016.
