The Merger Agreement contains customary representations, warranties and covenants, including covenants obligating the Company to continue to conduct its business in the ordinary course and to cooperate in seeking regulatory approvals.

The foregoing description of the Merger Agreement is not complete and is qualified in its entirety by the text of the Merger Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference. The Merger Agreement and the foregoing description of the Merger Agreement have been included to provide investors and stockholders with information regarding the terms of the Merger Agreement. They are not intended to provide any other factual information about the Company. The representations, warranties and covenants

contained in the Merger Agreement were made only as of specified dates for the purposes of such agreement, were solely for the benefit of the parties to such agreement and may be subject to qualifications and limitations agreed upon by such parties. In particular, in reviewing the representations, warranties and covenants contained in the Merger Agreement and discussed in the foregoing description, it is important to bear in mind that such representations, warranties and covenants were negotiated with the principal purpose of allocating risk between the parties, rather than establishing matters as facts. Such representations, warranties and covenants may also be subject to a contractual standard of materiality different from those generally applicable to stockholders and reports and documents filed with the U.S. Securities and Exchange Commission (the “SEC”), and are also qualified in important part by a confidential disclosure letter delivered by the Company to OpenText in connection with the Merger Agreement. Investors and stockholders should not rely on such representations, warranties and covenants as characterizations of the actual state of facts or circumstances described therein. Information concerning the subject matter of such representations, warranties and covenants may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the parties’ public disclosures.

Tender Agreement

In connection with the Offer and Merger, all members of the Board of Directors of the Company and certain officers of the Company have entered into a Tender and Voting Agreement (the “Tender Agreement”) agreeing to, among other things, tender all the shares beneficially owned by them pursuant to the Offer and to vote against any Competing Proposal (as defined in the Merger Agreement) or any merger, consolidation or other combination involving the Company, other than the Merger, unless the Merger Agreement is terminated. The Tender Agreement will terminate upon the termination of the Merger Agreement.

On July 26, 2017, the Company issued a press release announcing certain preliminary 2017 second quarter results (the “Earnings Press Release”). A copy of the press release is attached as Exhibit 99.1 to this report.

Item 8.01. Other Events.
