Execution Version

AGREEMENT

This Agreement (this “Agreement”) is made and entered into as of March 1, 2019 by and among Synacor, Inc., a Delaware corporation (the “Company”), and 180 Degree Capital Corp. (“180 Degree”) (each of the Company and 180 Degree, a “Party” to this Agreement, and collectively, the “Parties”).

RECITALS

WHEREAS, as of the date hereof, 180 Degree is deemed to beneficially own shares of common stock, par value $0.01 per share, of the Company (the “Common Stock”) totaling, in the aggregate, 2,839,206 shares (the “Shares”), or approximately 7.3%, of the Common Stock issued and outstanding as of the date hereof (the “180 Degree Ownership”); and

WHEREAS, the Company believes that Mr. Kevin M. Rendino, a representative of 180 Degree (the “180 Degree Designee”), has valuable perspectives and contributions to offer the Company as a significant stockholder, and accordingly desires to appoint the 180 Degree Designee to the Board of Directors of the Company (the “Board”), and the Company and 180 Degree desire to agree to certain matters related thereto 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 hereby acknowledged, the Parties hereto, intending to be legally bound hereby, agree as follows:

1. Board Matters, Nomination and Election of Directors and Related Agreements.

(a) Nomination and Election of Director. Immediately following the execution of this Agreement, (A) the size of the Board shall be increased from eight (8) to nine (9) members and (B) the 180 Degree Designee shall be appointed to serve as a Class III director of the Company with an initial term that comes up for re-election at the Company’s 2020 annual meeting of stockholders (the “2020 Annual Meeting”). The Board, based on information provided by 180 Degree and the 180 Degree Designee, has determined that the 180 Degree Designee would constitute an independent director of the Board under the applicable independence rules of (x) the Securities and Exchange Commission (the “SEC”) and (y) The Nasdaq Stock Market, LLC (“Nasdaq”) listing standards (the “Director Criteria”).

(b) Replacement Rights. If the 180 Degree Designee (or any 180 Degree Replacement (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 (as defined below), and at such time the 180 Degree Ownership (which at any measurement time during the Standstill Period shall include a combination of 180 Degree’s economic and beneficial ownership (as determined under Rule 13d-3 promulgated under the Exchange Act) is at least the lesser of 5.0% of the Company’s then outstanding Common Stock and 1,950,015 shares (subject to adjustment for stock splits, reclassifications, combinations and similar adjustments) (such lesser amount, the “Minimum Ownership Threshold”), 180 Degree shall have the ability to recommend a substitute person for appointment to the Board in accordance with this Section 1(b)

(any such replacement nominee shall be referred to as a “180 Degree Replacement,” and upon becoming a 180 Degree Replacement, such person shall be deemed a 180 Degree Designee for purposes of this Agreement). Any 180 Degree Replacement must (i) meet the Director Criteria, (ii) be a senior member of 180 Degree’s management team and (iii) be reasonably acceptable to the Board (such acceptance not to be unreasonably withheld).

(i) 180 Degree agrees that it will cause its controlled Affiliates and Associates to comply with the terms of this Agreement and shall be responsible for any breach of this Agreement by any such controlled Affiliate or Associate. As used in this Agreement, the terms “Affiliate” and “Associate” shall have the respective meanings set forth in Rule 12b-2 promulgated by the SEC 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; provided, however, that “Associates” shall not include any of 180 Degree’s investment holdings in which 180 Degree holds 10.0% or more of any class of equity securities.

(ii) 180 Degree agrees that it will appear in person or by proxy at each annual or special meeting of stockholders held during the Standstill Period and vote all Shares of Common Stock beneficially owned by 180 Degree at the meeting in favor of any proposal supported by a majority of the Board; provided, however, that 180 Degree shall have the right to vote in its sole discretion with respect to any Extraordinary Transaction (as defined below).

(iii) As soon as practicable following the execution of this Agreement, the 180 Degree Designee will submit to the Company (A) a fully completed copy of the Company’s standard director & officer questionnaire and other reasonable and customary director onboarding documentation required by the Company in connection with the election of new Board members, to the extent not previously provided to the Company; (B) an executed irrevocable resignation as a director pursuant to which the 180 Degree Designee agrees to resign from the Board and all applicable committees thereof if (1) at any time 180 Degree’s aggregate beneficial ownership of Common Stock decreases to less than the Minimum Ownership Threshold or (2) the resignation provisions of Section 2(a) hereof are implicated; and (C) a written acknowledgement that the 180 Degree Designee agrees to be bound by all current policies, codes and guidelines applicable to directors of the Company and further agrees to the recusal provisions set forth in Section 1(c)(iv) below.

(iv) 180 Degree agrees that the Board or any committee thereof, in the exercise of its fiduciary duties, may recuse the 180 Degree Designee from any Board or committee meeting or portion thereof at which the Board or any such committee is evaluating and/or taking action with respect to (A) the ownership of Shares by 180 Degree, (B) the exercise of any of the Company’s rights or enforcement of any of the obligations under this Agreement, (C) any action taken in response to actions taken or proposed by 180 Degree, its Affiliates or its Associates with respect to the Company or (D) any transaction proposed by, or with, 180 Degree, its Affiliates or its Associates.

(v) For so long as the 180 Degree Designee or any 180 Degree Replacement continues to serve on the Board, the Company will recommend, support and solicit proxies for the election of the 180 Degree Designee in the same manner as it recommends, supports and solicits proxies for the election of the Company’s other nominees at any annual or special meeting of stockholders at which such 180 Degree Designee or 180 Degree Replacement comes up for re-election to the Board.

(d) Director Compensation. The Company agrees that the 180 Degree Designee or any 180 Degree Replacement shall receive (i) the same benefits of director and officer insurance, and any indemnity and exculpation arrangements available generally to the directors on the Board, (ii) the same compensation for his or her service as a director as the compensation received by other non-employee directors on the Board and (iii) such other benefits on the same basis as all other non-employee directors on the Board.

2. Certain Provisions.

(a) The Standstill Period (the “Standstill Period”) begins on the date of this Agreement and shall extend until ten (10) days prior to the deadline for the submission of stockholder nominations for directors for the 2020 Annual Meeting pursuant to the Company’s Bylaws; provided that if the Company shall offer to nominate the 180 Degree Designee (or the 180 Degree Replacement Director, if applicable) for re-election at the 2020 Annual Meeting (which offer shall be made by the Company not less than ten (10) days prior to the expiration of the Standstill Period), then the Standstill Period shall be automatically extended to the day following the Company’s 2020 annual meeting of stockholders; provided, further, that if the Standstill Period is extended in accordance with this sentence and if any member of 180 Degree, its Affiliates or Associates takes any action with any Third Party (as hereinafter defined) in connection with, or advises any Third Party that it is considering, conducting a proxy contest at any annual or special meeting of stockholders of the Company held during the Standstill Period or provides the Company with a notice of nomination of director(s) at any annual or special meeting of stockholders held during the Standstill Period, concurrently with such event the 180 Degree Designee (or any 180 Degree Replacement Director, if applicable) will resign from the Board.

(b) 180 Degree agrees that during the Standstill Period, neither 180 Degree nor any of its Affiliates or Associates under its control or direction will, and 180 Degree will cause each of its Affiliates and Associates under its control not to, directly or indirectly, in any manner, alone or in concert with others:

(ii) form, join or in any way participate in any “group” (within the meaning of Section 13(d)(3) of the Exchange Act) with respect to any securities of the Company (other than a “group” that includes all or some of the persons identified on Exhibit A, but does not include any other entities or persons not identified on Exhibit A as of the date hereof (any such person, a “Third Party”)); provided, however, that nothing herein shall limit the ability of an Affiliate of 180 Degree to join the “group” following the execution of this Agreement, so long as any such Affiliate agrees to be bound by the terms and conditions of this Agreement;

(iii) agree, attempt, seek or propose to deposit any securities of the Company in any voting trust or similar arrangement, or subject any securities of the Company to any arrangement or agreement with respect to the voting thereof, other than any such voting trust, arrangement or agreement solely among 180 Degree, Affiliates or Associates of 180 Degree and otherwise in accordance with this Agreement;

(iv) (A) nominate or recommend for nomination any person for election at any annual or special meeting of stockholders held during the Standstill Period, directly or indirectly, (B) submit any proposal for consideration at, or bring any other business before, any annual or special meeting of stockholders held during the Standstill Period, directly or indirectly, or (C) initiate, encourage or participate in any “withhold” or similar campaign with respect to the any annual or special meeting of stockholders held during the Standstill Period, directly or indirectly.

(v) seek, or encourage any person, to submit nominations in furtherance of a “contested solicitation” for the election or removal of directors with respect to the Company or seek, encourage or take any other action with respect to the election or removal of any directors;

(vi) with respect to the Company or the Common Stock, make any communication or announcement (other than in the ordinary course of its business on a confidential basis to their investors) stating how its shares of Common Stock will be voted, or the reasons therefor or otherwise communicate pursuant to Rule 14a-1(l)(2)(iv) under the Exchange Act; provided that the foregoing shall not apply to any disclosure required to be made by 180 Degree pursuant to applicable federal or state law, rule or regulation;

(vii) effect or seek to effect, offer or propose to effect, cause or participate in, or assist or facilitate any other person to effect or seek, offer or propose to effect or participate in, any tender or exchange offer, merger, acquisition, recapitalization, restructuring, disposition, distribution, spin-off, asset sale, joint venture or other business combination involving the Company or any of its Affiliates (each, an “Extraordinary Transaction”), or make any public statement or public disclosure regarding any intent, purpose, plan or proposal with respect to the Board, the Company, its management, policies or affairs or any of its securities or assets (including with respect to an Extraordinary Transaction) or this Agreement, that is inconsistent with the provisions of this Agreement, including any intent, purpose, plan or proposal that is conditioned on, or would require waiver, amendment, nullification or invalidation of, any provision of this Agreement or take any action that could require the Company to make any public disclosure relating to any such intent, purpose, plan, proposal or condition;

(viii) purchase or cause to be purchased or otherwise acquire or agree to acquire beneficial ownership of any Common Stock or other securities issued by the Company, or any securities convertible into or exchangeable for Common Stock, if, in any such case immediately after the taking of such action, 180 Degree together with its Affiliates and Associates would, in the aggregate, beneficially own, or have an economic interest in, an amount that would equal to or exceed 10.0% of the then outstanding shares of Common Stock (the “Ownership Limit”); provided, however, that the Board may increase the Ownership Limit by an affirmative vote of a majority of the Board;

(ix) (A) call or seek to call or request the call of any meeting of stockholders, (B) seek, alone or in concert with others, representation on, or nominate any candidate to, the Board, except as specifically set forth in Section 1, (C) seek the removal of any member of the Board, (D) conduct a referendum of stockholders or (E) make a request for any stockholder list or other Company books and records in its capacity as a stockholder;

(xi) enter into any arrangements, understanding or agreements (whether written or oral) with, or advise, finance, assist, seek to persuade or knowingly encourage, any Third Party to take any action in connection with any of the foregoing, or otherwise take or cause any action inconsistent with any of the foregoing; or

(xii) make any request or submit any proposal to amend the terms of this Agreement other than through non-public communications with the Company that would not be reasonably determined to trigger public disclosure obligations for any Party.

(c) Nothing in Section 2(b) shall be deemed to limit the exercise in good faith by the 180 Degree Designee of his fiduciary duties solely in his capacity as a director of the Company and in a manner consistent with his and 180 Degree’s obligations under this Agreement.

(d) The Company hereby acknowledges that the 180 Degree Designee has certain rights to indemnification, advancement of expenses and/or insurance provided by 180 Degree and certain of its Affiliates (collectively, the “Fund Indemnitors”). The Company hereby agrees (i) that it is the indemnitor of first resort (i.e., its obligations to 180 Degree Designee are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by 180 Degree Designee are secondary), (ii) that it shall be required to advance the full amount of expenses incurred by 180 Degree Designee and shall be liable for the full amount of all expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement and the Certificate of Incorporation or Bylaws of the Company (or any other agreement between the Company and 180 Degree Designee), without regard to any rights 180 Degree Designee may have against the Fund Indemnitors, and, (iii) that it irrevocably waives,

relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Fund Indemnitors on behalf of 180 Degree Designee with respect to any claim for which 180 Degree Designee has sought indemnification from the Company shall affect the foregoing and the Fund Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of 180 Degree Designee against the Company. The Company and 180 Degree Designee agree that the Fund Indemnitors are express third party beneficiaries of the terms of this Section 2(d).
