Settlement Agreement

On March 24, 2016, Edgewater Technology, Inc. (the “Company”) entered into an Agreement (the “Agreement”) with Lone Star Value Investors, LP and others (collectively, “Lone Star Value”) in connection with the expansion of the Board of Directors of the Company (the “Board”) and the addition of two new independent directors—Stephen R. Bova, an independent business strategy consultant, and Timothy Whelan, a Co-Founder and Managing Director of Echo Financial Business Consulting—to fill the newly created directorships, effective March 24, 2016. On March 24, 2016, the Company issued a press release announcing the election of Messrs. Bova and Whelan, a copy of which release is filed as Exhibit 99.1 to this Current Report on Form 8-K and incorporated herein by reference.

Under the terms of the Agreement, the Company agreed, among other things, that it will take all necessary actions to increase the size of the Board from six to eight directors, elect Messrs. Bova and Whelan to fill the resulting vacancies and nominate Messrs. Bova and Whelan to be elected as directors at the Company’s 2016 Annual Meeting of Stockholders (the “2016 Annual Meeting”). Pursuant to the Agreement, Lone Star Value will vote all of the shares of the Company’s common stock (the “Common Stock”) that it beneficially owns for the election of the Board’s nominees for director at the 2016 Annual Meeting. Lone Star Value will also vote in accordance with the recommendation of the Board on all other matters submitted for stockholder vote at the 2016 Annual Meeting; provided, however, that to the extent the recommendation of both Institutional Shareholder Services Inc. (“ISS”) and Glass, Lewis & Co., LLC (“Glass Lewis”) differs from the Board’s recommendation with respect to any matter, other than nominees for election as directors to the Board, Lone Star Value shall have the right to vote in accordance with the recommendation of ISS and Glass Lewis with respect to such matters.

The Agreement further provides that Lone Star Value will not nominate any person for election at or submit any proposal for consideration at the 2016 Annual Meeting, nor will Lone Star Value initiate, encourage or participate in any “withhold” or similar campaign with respect to the 2016 Annual Meeting. Lone Star Value is also subject to standstill provisions under the Agreement. Such provisions generally remain in effect until the date that is 30 days prior to the expiration of the Company’s advance notice period for the nomination of directors at the Company’s 2017 Annual Meeting of Stockholders. These provisions restrict Lone Star Value’s ability to engage in certain proxy solicitations, make certain stockholder proposals, call meetings of stockholders, solicit consents from stockholders, obtain additional representation on the Board or seek to remove any of the Company’s directors.

The foregoing description of the Agreement is qualified in its entirety by reference to the Agreement, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.

Bova and Timothy Whelan in connection with his election as a director of the Company (the “Indemnification Agreement”). The Indemnification Agreement provides indemnity, including the advancement of expenses, to the director against liabilities incurred in the performance of his duties to the fullest extent permitted by the General Corporation Law of the State of Delaware. The foregoing description of the Indemnification Agreement is qualified in its entirety by reference to the form of Indemnification Agreement, a copy of which is filed as Exhibit 10.2 to this Current Report on Form 8-K and incorporated herein by reference.

Bova and Whelan entered into an Indemnification Agreement in connection with his election and received a nonstatutory stock option to purchase 20,000 shares of Common Stock at an exercise price of $7.61 per share, which was the closing price of the Common Stock on the Nasdaq Stock Market on March 24, 2016. Each nonstatutory stock option has a term of five years and vests in three equal annual installments.
