As previously disclosed, on January 6, 2014, Verint Systems Inc. (“Verint”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Kiwi Acquisition Inc., an indirect, wholly owned subsidiary of Verint (“Merger Sub”), Kay Technology Holdings, Inc. (“KANA”) and Accel-KKR Capital Partners III, LP, providing for the merger, upon the terms and subject to the conditions set forth in the Merger Agreement, of Merger Sub with and into KANA with KANA continuing as the surviving corporation and an indirect, wholly owned subsidiary of Verint (the “Merger”). Subject to the terms and conditions of the Merger Agreement, the merger consideration will consist of cash in an amount equal to $514 million, subject to certain closing adjustments set forth in the Merger Agreement. A portion of the consideration paid in the Merger is expected to be financed using the proceeds of incremental term loans on terms similar to Verint’s existing term loans under its secured credit agreement.

In connection with the proposed financing, Verint expects to make a presentation to lenders and prospective lenders (the “Lender Presentation”). A copy of the Lender Presentation is furnished as Exhibit 99.1 to this Current Report and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934.

The information contained in the Lender Presentation is summary information that should be considered in the context of Verint’s filings with the Securities and Exchange Commission and other public announcements that Verint may make by press release or otherwise from time to time. The Lender Presentation speaks as of the date of this Current Report. While Verint may elect to update the Lender Presentations in the future to reflect events and circumstances occurring or existing after the date of this Current Report, Verint specifically disclaims any obligation to do so, except as may be required by law. By furnishing the Lender Presentation with this Current Report, Verint makes no admission as to the materiality of any information in the Lender Presentation.
