RECITALS

WHEREAS, the Company and Starboard have engaged in various discussions and communications concerning the Company’s business, financial performance and strategic plans;

WHEREAS, as of the date of this Agreement, Starboard has a combined economic and beneficial ownership (as determined under Rule 13d-3 promulgated under the Exchange Act (as defined below)) interest in the common stock, par value $0.01 per share, of the Company (the “Common Stock”) totaling, in the aggregate, 6,377,000 shares (the “Shares”), or approximately 8.9% of the Common Stock issued and outstanding on the date of this Agreement (“Starboard’s Ownership”); and

WHEREAS, as of the date of this Agreement, the Company and Starboard have determined to come to an agreement with respect to the composition of the Board of Directors of the Company (the “Board”) and certain other matters, as provided in this Agreement.

NOW, THEREFORE, in consideration of the foregoing premises and the mutual covenants and agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are acknowledged, the Parties to this Agreement, intending to be legally bound, agree as follows:

1.Board Appointments; Leadership Structure and Related Agreements.

(a)Board Appointments.

(i)The Company agrees that, as promptly as practicable after the completion of the 2018 annual meeting of stockholders of the Company (the “2018 Annual Meeting”), the Board and all applicable committees of the Board shall take all necessary actions to increase the size of the Board from eight (8) to eleven (11) and to appoint to the Board each of: Michael Kelly and Bryan Wiener (each, a “Starboard Designee”) and an additional director to be mutually agreed by the Company and Starboard pursuant to Section 1(a)(ii) hereof (the “Additional Independent Director”, and together with the Starboard Designees, each a “New Appointee”).

(ii)Within thirty-five (35) days following the execution of this Agreement, each of Starboard and the Nominating and Corporate Governance Committee of the Board (the “Nominating Committee”) shall submit to the other the names of two (2) individuals for consideration as Additional Independent Director candidates. Each such candidate submitted by Starboard must (A) be independent of Starboard (for the avoidance of doubt, the nomination by Starboard of any person to serve on the board of another company shall not (in and of itself) cause such person not to be deemed independent of Starboard), (B) qualify as “independent” pursuant to New York Stock Exchange (the “NYSE”) listing standards, (C) have the relevant financial and business experience to be a director of the Company, and (D) satisfy the publicly disclosed guidelines and policies with respect to service on the Board. Promptly thereafter, Starboard and Mr. Scott Forbes shall meet to discuss such Additional Independent Director candidates (which discussions shall be conducted reasonably and in good faith) and mutually agree on which candidate(s) the Parties will interview. Each Party shall use its reasonable best efforts to conduct any interview(s) of the mutually agreed upon Additional Independent Director candidate(s) as promptly as practicable after such meeting, but in any case, assuming reasonable availability of the applicable candidate(s), within ten (10) business days after such meeting. As promptly as practicable after the Parties have conducted such interview(s), the Parties shall discuss (which discussions shall be conducted reasonably and in good faith) and mutually agree on an Additional Independent Director candidate to recommend to the Board for appointment to the Board (the “Preferred Candidate”). Within five (5) business days following the receipt of such recommendation as to the Preferred Candidate, the Board shall vote on the appointment of the Preferred Candidate to the Board; provided, however, that if the Board does not appoint the Preferred Candidate to the Board, the Parties shall continue to follow the procedures of this Section 1(a)(ii) until a candidate mutually agreed upon by the Parties is appointed to the Board as the Additional Independent Director. Effective upon the appointment of the Additional Independent Director to the Board, such Additional Independent Director will be considered a New Appointee for all purposes of this Agreement. The Parties acknowledge and agree that it is their intent that the Additional Independent Director shall be appointed to the Board as promptly as practicable after completion of the 2018 Annual Meeting.

(iii)If any Starboard Designee (or any Starboard Replacement Director (as defined below)) is unable or unwilling to serve as a director, resigns as a director or is removed as a director prior to the expiration of the Standstill Period, and at such time Starboard’s Ownership (which at any measurement time during the Standstill Period shall include a combination of Starboard’s economic and beneficial ownership (as determined under Rule 13d-3 promulgated under the Exchange Act) of shares of Common Stock as of such time) is at least the lesser of 3.0% of the Company’s then outstanding Common Stock and 2,155,900 shares of Common Stock (subject to adjustment for stock splits, reclassifications, combinations and similar adjustments) (such lesser amount, the “Minimum Ownership Threshold”), Starboard shall have the ability to recommend a substitute person(s) for appointment to the Board in accordance with this Section 1(a)(iii) (any such replacement nominee shall be referred to as a “Starboard Replacement Director”, and upon becoming a Starboard Replacement Director, such person shall become a New Appointee for purposes of this Agreement). Any Starboard Replacement Director must (A) be independent of Starboard (for the avoidance of doubt, the nomination by Starboard of any person to serve on the board of another company shall not (in and of itself) cause such person not to be deemed independent of Starboard), (B) qualify as “independent” pursuant to NYSE listing standards, (C) have the relevant financial and business experience to be a director of the Company, and (D) satisfy the publicly disclosed guidelines and policies with respect to service on the Board (in the case of each of (A) through (D), as reasonably determined by the Nominating Committee). The Nominating Committee shall make its determination and recommendation (which it shall undertake reasonably and in good faith) regarding whether such person meets the foregoing criteria within five (5) business days after (1) such nominee as a Starboard Replacement Director has submitted to the Company the documentation required by Section 1(d)(v) and (2) representatives of the Board have, if requested by the Company, conducted customary interview(s) of such nominee. The Company shall use its reasonable best efforts to conduct any interview(s) contemplated by this Section 1(a)(iii) as promptly as practicable, but in any case, assuming reasonable availability of the nominee, within ten (10) business days after Starboard’s recommendation of such nominee. In the event the Nominating Committee does not accept a person recommended by Starboard as the Starboard Replacement Director, Starboard shall have the right to recommend additional substitute person(s) whose appointment shall be subject to the Nominating Committee recommending such person in accordance with the procedures described above. The Board shall vote on the appointment of such Starboard Replacement Director to the Board no later than five (5) business days after the Nominating Committee recommendation of such Starboard Replacement Director; provided, however, that if the Board does not appoint such Starboard Replacement Director to the Board pursuant to this Section 1(a)(iii), the Parties shall continue to follow the procedures of this Section 1(a)(iii) until a Starboard Replacement Director is appointed to the Board. Upon a Starboard Replacement Director’s appointment to the Board, the Board and all applicable committees of the Board shall take all necessary actions to appoint such Starboard Replacement Director to any applicable committee of the Board of which the replaced director was a member immediately prior to such director’s resignation or removal or, if the Board or the applicable committee of the Board determines that the Starboard Replacement Director does not satisfy the requirements of the NYSE and applicable law with respect to service on the applicable committee (which determination shall be made reasonably and in good faith), to an alternative committee of the Board. Until such time as any Starboard Replacement Director is appointed to any applicable committee, one of the other New Appointees (as designated by Starboard) will serve as an interim member of such applicable committee; provided, that, if the Board or the applicable committee of the Board determines that the New Appointee designated by Starboard does not satisfy the requirements of the NYSE and applicable law with respect to service on the applicable committee (which determination shall be made reasonably and in good faith), the Board may designate another member of the Board to serve as an interim member of such committee during such interim period.

2

(iv)If the Additional Independent Director (or any replacement thereof pursuant to this section) is unable or unwilling to serve as a director, resigns as a director or is removed as a director prior to the expiration of the Standstill Period, and at such time Starboard’s Ownership (which at any measurement time during the Standstill Period shall include a combination of Starboard’s economic and beneficial ownership (as determined under Rule 13d-3 promulgated under the Exchange Act) of shares of Common Stock as of such time) is no less than the Minimum Ownership Threshold, the Parties shall follow the procedures of Section 1(a)(ii) until a candidate mutually agreed upon by the Parties is appointed to the Board as a replacement for the Additional Independent Director (upon such replacement’s appointment to the Board, such replacement shall become the Additional Independent Director for purposes of this Agreement). Upon such replacement’s appointment to the Board, the Board and all applicable committees of the Board shall take all necessary actions to appoint such replacement to any applicable committee of the Board of which the Additional Independent Director was a member immediately prior to such director’s resignation or removal or, if the Board or the applicable committee of the Board determines that the replacement does not satisfy the requirements of the NYSE and applicable law with respect to service on the applicable committee (which determination shall be made reasonably and in good faith), to an alternative committee of the Board.

(v)During the period commencing with the date of this Agreement through the expiration or termination of the Standstill Period (as defined below), the Board and all applicable committees of the Board shall take all necessary actions so that the size of the Board is no more than eight (8) directors except for such increase to the size of the Board (which shall be to no more than eleven (11) directors) as necessary for the appointment of the New Appointees to the Board, unless Starboard consents in writing to enlarging the Board.

3

(vi)During the period commencing with the date of this Agreement through the appointment of each Starboard Designee to the Board (the “Observer Period”), each Starboard Designee shall be an observer to the Board (each, an “Observer”) who shall receive copies of all documents distributed to the Board during the Observer Period, including notice of all meetings of the Board, all written consents executed by the Board, all materials prepared for consideration at any meeting of the Board, and all minutes related to each meeting of the Board contemporaneous with their distribution to the Board. Each Observer shall be permitted to attend and reasonably participate, but not vote, at all meetings of the Board during the Observer Period (whether such meetings are held in person, telephonically or otherwise). Notwithstanding the foregoing, the Company reserves the right to exclude any Observer from access to any material or meeting or portion thereof if, and only to the extent that, the Board determines reasonably and in good faith that such exclusion is necessary to preserve the attorney-client privilege. As a condition to serving as an Observer, each Observer shall (i) deliver to the Company a written representation that such person will comply with all applicable publicly disclosed confidentiality, corporate governance, conflict of interest, Regulation FD, code of conduct and ethics, and stock ownership and trading policies and guidelines of the Company that have been provided to such person prior to such date and (ii) enter into a customary confidentiality agreement in substantially the form entered into by the members of the Board.

(vii)Starboard, on behalf of itself and its Affiliates, hereby (i) irrevocably withdraws the notice of stockholder nomination of individuals for election as directors at the 2018 Annual Meeting submitted to the Company on February 22, 2018, and (ii) irrevocably withdraws any related materials or notices submitted to the Company in connection therewith.

(b)New Appointee Committee Representation.

(i)Subject to the Company’s corporate governance guidelines and NYSE rules and applicable laws, the Board and all applicable committees of the Board shall take all actions necessary to ensure that from and after the appointment of the New Appointees to the Board pursuant to Section 1(a) and through the end of the Standstill Period, (A) Michael Kelly is appointed to the Audit Committee of the Board and the Compensation Committee of the Board (the “Compensation Committee”), (B) Bryan Wiener is appointed to the Compensation Committee and the Nominating Committee, (C) the Additional Independent Director shall be appointed to such committee or committees of the Board (for avoidance of doubt, to at least one committee of the Board) as determined by the Nominating Committee, (D) each New Appointee will serve on at least one committee of the Board and (E) each committee of the Board, including any new committee(s) that may be established, shall include at least one of the New Appointees.

(ii)Without limiting Section 1(b)(i), the Board shall give the New Appointees the same due consideration for membership to any committee of the Board as any other independent director.

4

(c)2018 Annual Meeting. The Company agrees to hold the 2018 Annual Meeting no later than May 31, 2018, subject to any delay necessitated by compliance with applicable law or regulatory or judicial order or requirement.

(d)Additional Agreements.

As used in this Agreement, the terms “Affiliate” and “Associate” shall have the respective meanings set forth in Rule 12b-2 promulgated by the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended, or the rules or regulations promulgated thereunder (the “Exchange Act”), and shall include all persons or entities that at any time during the term of this Agreement become Affiliates or Associates of any person or entity referred to in this Agreement.

(ii)Upon execution of this Agreement, Starboard hereby agrees that except as provided herein Starboard will not, and that it will not permit any of its controlled Affiliates or Associates to, (A) nominate or recommend for nomination any person for election at the 2018 Annual Meeting, directly or indirectly, (B) submit any proposal for consideration at, or bring any other business before, the 2018 Annual Meeting, directly or indirectly, or (C) initiate, encourage or participate in any “vote no,” “withhold” or similar campaign with respect to the 2018 Annual Meeting, directly or indirectly. Starboard shall not publicly or privately encourage or support any other stockholder to take any of the actions described in this Section 1(d)(ii).

(iii)Starboard agrees that it will appear in person or by proxy at the 2018 Annual Meeting and vote all shares of Common Stock beneficially owned by Starboard at the 2018 Annual Meeting (A) in favor of the Company’s nominees and (B) in favor of the ratification of the appointment of Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2018.

(iv)Starboard shall promptly (and in any event within five (5) business days) inform the Company in writing if at any time Starboard’s Ownership of Common Stock decreases to less than the Minimum Ownership Threshold.

(v)Prior to the date of this Agreement, the Starboard Designees have submitted to the Company a fully completed copy of the Company’s standard director & officer questionnaire and other reasonable and customary director onboarding documentation (including an authorization form to conduct a background check) required by the Company in connection with the appointment or election of new Board members.

5

(vi)The New Appointees, in addition to all current directors, will be required to (A) comply with all policies, procedures, codes, rules, standards and guidelines applicable to members of the Board and (B) keep confidential all Company confidential information and not disclose to any third parties (including Starboard) discussions or matters considered in meetings of the Board or Board committees.

(vii)The Company agrees that the Board and all applicable committees of the Board shall, to the extent that the Board and such committees have such authority or are entitled to so determine, take all necessary actions, effective no later than immediately following the appointment of each New Appointee, to determine, in connection with his or her initial appointment as a director and nomination by the Company at the 2018 Annual Meeting, as applicable, that such New Appointee is deemed to be (A) a member of the Incumbent Board (as such term may be defined in the definition of “Change in Control” or any similar term under Company incentive plans, options plans or employment agreements, including, without limitation, the Company’s Omnibus Incentive Compensation Plan, Deferred Compensation Plan or any other related plans or agreements that refer to any such plan’s definition of “Change in Control” or any similar term) and (B) a member of the Board as of the beginning of any applicable measurement period for the purposes of the definition of “Change in Control” or any similar term under certain incentive plans, options plans or employment agreements of the Company, including, without limitation, any severance plan or change-in-control severance plan.

The Consulting Firm shall report its findings and recommendations to the full Board, it being understood and agreed that the Company shall not be required to adopt or implement any such recommendations absent approval of the Board.

(ix)The Board shall review and recommend targeted ranges for revenue and adjusted EBITDA margins for fiscal years 2019, 2020 and 2021, which the Board shall determine after consideration of the recommendations made by the Consulting Firm, consistent with the prior presentation of similar targeted ranges for such metrics by the Company to its stockholders (as approved by the Board, the “Targets”). On or prior to February 28, 2019, the Company shall issue a press release or public announcement publishing the Targets (the date of such announcement, the “Target Announcement Date”).

6

(x)From the date of this Agreement until each Starboard Designee is appointed to the Board, the Company and the Board shall not take any actions to amend, or seek to amend, the Company’s governance structure, including through amendments to the Company’s Certificate of Incorporation and/or Bylaws, in a way that materially reduces, from a governance perspective, the rights of the Company’s stockholders.

2.Standstill Provisions.
