Cautionary Note Regarding Forward-Looking Statements

This Current Report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements generally relate to future events or our future financial or operating performance. Forward-looking statements may contain words such as “will be,” “will,” “expects,” “expected,” “intends,” “continue,” or similar expressions, and include the assumptions that underlie such statements. These forward-looking statements include statements about future financial and operating results; benefits of the transaction to customers, stockholders and employees; potential synergies and cost savings; the ability of the combined company to drive growth and expand client relationships; the financing of the transaction and other statements regarding the proposed transaction. The Company’s expectations and beliefs regarding these matters may not materialize, and actual results in future periods are subject to risks and uncertainties that could cause actual results to differ materially from those projected, including but not limited to:

• failure of the Company’s stockholders to adopt the merger agreement or that the companies will otherwise be unable to consummate the merger on the terms set forth in the merger agreement;

• the risk that the businesses will not be integrated successfully;

• the risk that synergies will not be realized or realized to the extent anticipated;

• uncertainty as to the market value of the Gartner merger consideration to be paid in the merger;

• the risk that required governmental approvals of the merger will not be obtained;

• the risk that Gartner following this transaction will not realize its financing or operating strategies;

• litigation in respect of either the Company or the merger; and

• disruption from the merger making it more difficult to maintain certain strategic relationships.

The forward-looking statements contained in the Current Report are also subject to other risks and uncertainties, including those more fully described in our filings with the Securities and Exchange Commission (“SEC”), including our Annual Report on Form 10-K for the year ended December 31, 2015, which was filed with the Securities and Exchange Commission on February 29, 2016 and those discussed in “Risk Factors” in the S-4 filed by Gartner with the SEC on February 6, 2017 and in the documents which are incorporated by reference therein. The forward-looking statements in this press release are based on information available to the Company as of the date hereof, and the Company disclaims any obligation to update any forward-looking statements, except as required by law.

Additional Information and Where to Find It

This Current Report does not constitute an offer to sell or the solicitation of an offer to buy any securities, or a solicitation of any vote or approval, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction.

This Current Report is being made in respect of a proposed business combination involving Gartner and the Company. In connection with the proposed transaction, Gartner filed with the SEC a Registration Statement on Form S-4 on February 6, 2017 that includes the preliminary proxy statement of the Company and that also constitutes a preliminary prospectus of Gartner. The information in the preliminary proxy statement/prospectus is not complete and may be changed. Gartner may not issue the common stock referenced in the proxy statement/prospectus until the Registration Statement on Form S-4 filed with the SEC becomes effective. The preliminary proxy statement/prospectus, this Current Report on Form 8-K and any related communication are not offers to sell Gartner securities, are not soliciting an offer to buy Gartner securities in any state where the offer and sale is not permitted and are not a solicitation of any vote or approval. The definitive proxy statement/prospectus will be mailed to stockholders of the Company.
