Item 1.01. Entry into a Material Definitive Agreement.

On December 22, 2014, SeaChange International, Inc. (“SeaChange”) agreed to acquire TLL, LLC (“Timeline Labs”), pursuant to an Agreement and Plan of Merger (the “Merger Agreement”). Timeline Labs is a California-based SaaS company that enables local broadcasters, national news organizations and other media companies and brands to analyze social media messages in real-time, find and broadcast social trends, and measure viewing audience engagement across television, mobile and personal computers. The Merger Agreement has been approved by the boards of SeaChange and Timeline Labs, and, subsequent to signing, by the equityholders of Timeline Labs. Approval by the SeaChange stockholders is not required in connection with the transaction.

Upon the terms and subject to the conditions set forth in the Merger Agreement, the Merger Sub will merge with and into Timeline Labs (the “Merger”), with Timeline Labs continuing after the Merger as the surviving company and a wholly owned subsidiary of SeaChange. On the signing date pursuant to the Merger Agreement, SeaChange made an escrow deposit of $2,500,000 (the “Deposit Escrow”), which may be drawn upon by Timeline Labs for working capital purposes prior to the closing under the Merger Agreement, subject to an agreed upon cash flow plan. At the effective time of the Merger, each outstanding Timeline Labs equity unit will convert into the right to receive a portion of the following cash and stock amounts, each as specified in the Merger Agreement:

Shares of SeaChange issuable pursuant to the Merger Agreement are issuable in a private placement exempt from registration pursuant to Section 4(a)(2) of the Securities Act of 1933 and Rule 506 thereunder. SeaChange has agreed to file a resale registration statement subsequent to consummation of the Merger.

Under the Merger Agreement, the former equityholders of Timeline Labs may on or prior to January 5, 2015 submit a nominee to serve on the SeaChange Board of Directors (the “Board”), which nominee would be appointed to the Board, subject to SeaChange’s customary director evaluation policies and procedures, effective as of the closing. This nomination right continues until the earlier of January 31, 2017 (the end of the earnout period), the date on which the maximum earnout consideration has been paid in full and a change in control of SeaChange.

The Merger Agreement includes customary representations, warranties and covenants by the parties. Consummation of the Merger is subject to customary conditions, including, among other things: (i) the accuracy of representations made by Timeline Labs in the Merger Agreement, and (ii) the material performance by Timeline Labs of its obligations under the Merger Agreement.

Payments under the Merger Agreement subsequent to closing are subject to reduction should there have been a breach of the representations, warranties, covenants and agreements contained in the Merger Agreement. In addition, in limited circumstances, amounts paid at closing are subject to forfeiture should there have been a breach of certain specified representations, warranties and covenants contained in the Merger Agreement.

The terms of the Merger Agreement and the transactions contemplated thereby are the result of arm’s length negotiation among the parties.

The foregoing description of the Merger Agreement is qualified in its entirety by reference to the full text of the Merger Agreement, which is attached as Exhibit 2.1 to this report and is incorporated in this report by reference. A copy of SeaChange’s press release announcing the transaction is attached hereto as Exhibit 99.1.

The Merger Agreement has been attached as an exhibit to provide investors and security holders with information regarding its terms. It is not intended to provide any other factual information about SeaChange, the Merger Sub or Timeline Labs. The representations, warranties and covenants contained in the Merger Agreement were made only for the purposes of such agreement and as of specified dates, were solely for the benefit of the parties to such agreement, and may be subject to limitations agreed upon by the contracting parties. Certain of the representations and warranties have been made for the purposes of allocating contractual risk between the parties to the agreement instead of establishing these matters as facts. Investors are not third-party beneficiaries under the Merger Agreement. In addition, the representations and warranties contained in the Merger Agreement (i) are qualified by information in a confidential disclosure schedule that the parties have exchanged, (ii) were made only as of the date of such agreement or a prior, specified date, and (iii) in some cases are subject to qualifications with respect to materiality, knowledge and/or other matters, including standards of materiality applicable to the contracting parties that differ from those applicable to investors. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in SeaChange’s public disclosures. Accordingly, investors should not rely on the representations and warranties as characterizations of the actual state of facts or condition of SeaChange or Timeline Labs or any of their respective subsidiaries or affiliates.
