This Nomination and Standstill Agreement, dated March 5, 2015 (this “Agreement”), is by and among Axcelis Technologies, Inc. (the “Company”) and the entities and natural persons listed on  Exhibit A hereto and their respective Affiliates (collectively, “Vertex”) (each of the Company and Vertex, a “Party” to this Agreement, and collectively, the “Parties”).

RECITALS

WHEREAS, Vertex is deemed to beneficially own shares of common stock of the Company (the “Common Stock”) totaling, in the aggregate 7,458,668 shares, or approximately 6.7% percent, of the Common Stock of the Company issued and outstanding on the date hereof;

WHEREAS, Vertex submitted a nomination letter to the Company on February 9, 2015 (the “Nomination Letter”) nominating six (6) director candidates to be elected to the Company’s board of directors (the “Board”) at the 2015 annual meeting of stockholders of the Company (the “2015 Annual Meeting”); and

WHEREAS, the Company and Vertex have determined to come to an agreement with respect to the election of members of the Board at the 2015 Annual Meeting, certain matters related to the 2015 Annual Meeting 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 hereby acknowledged, the Parties, intending to be legally bound, agree as follows:

1.             Board Matters; Board Nominations; 2015 Annual Meeting; Committees; and Other Company Matters.

(a)           Upon the execution of this Agreement, Vertex hereby irrevocably withdraws its Nomination Letter and nominees, and any and all related materials and notices submitted to the Company in connection therewith, including its demand for stockholder list materials pursuant to Section 220 of the Delaware General Corporation Law (the “DGCL”), and Vertex will not (i) nominate any person for election at the 2015 Annual Meeting, (ii) submit any proposal for consideration at, or bring any other business before, the 2015 Annual Meeting, directly or indirectly, or (iii) initiate, encourage or participate in any “withhold” or similar campaign with respect to the 2015 Annual Meeting, directly or indirectly, and will not permit any of its Affiliates or Associates to do any of the items in this Section 1(a).  Vertex will not publicly or privately encourage or support any other stockholder to take any of the actions described in this Section 1(a).

(b)           The Company agrees that:

(1)           prior to the mailing of the Company’s definitive proxy statement for the 2015 Annual Meeting, the Board shall take all necessary action to nominate Richard J. Faubert and John T. Kurtzweil (collectively, the “New 2015 Nominees”), together with Thomas St. Dennis; R. John Fletcher; Arthur L. George, Jr.; Joseph Keithley; Barbara J. Lundberg; Patrick H. Nettles; and Mary G. Puma (altogether, the “2015 Nominees”), for election as directors of the Company as part of the Company’s director slate of nominees for the 2015 Annual Meeting;

(2)           it will recommend, support and solicit proxies for the election of the New 2015 Nominees in the same manner as for the Company’s other 2015 Nominees at the 2015 Annual Meeting;

(3)           as of the date of this Agreement, each of the New 2015 Nominees is appointed as an observer to the Board until the 2015 Annual Meeting.  Accordingly, with respect to meetings of the full Board, if any, prior to the 2015 Annual Meeting (whether telephone or in-person), each of the New 2015 Nominees will (i) receive copies of all notices and written information furnished to the full Board, reasonably in advance of each meeting to the extent practicable, and (ii) be permitted to be present at all meetings of the full Board (whether by telephone or in person). Notwithstanding the foregoing, (A) the Company shall be entitled to withhold any information and exclude each of the New 2015 Nominees from any meeting, or any portion thereof, as is reasonably determined by the Company to be necessary to protect the Company’s attorney-client privilege, or as otherwise may be appropriate until each of the New 2015 Nominees is elected to the Board, and (B) each of the New 2015 Nominees shall execute a confidentiality agreement in form and substance reasonably acceptable to the Company with respect to the information and discussions to which he will have access;

(4)           the Company will use its reasonable best efforts to hold the 2015 Annual Meeting no later than May 13, 2015;

(5)           the Company agrees that at the first meeting of the Board following each of the New 2015 Nominee’s election to the Board, the Board will take all action necessary in furtherance of the appointment of each of the New 2015 Nominees to at least one committee of the Board whether now existing or hereafter created during the Standstill Period assuming they meet legal and stock exchange requirements for each such committee;

(6)           if either of the New 2015 Nominees or any Replacement Director (as defined below) is unable to serve as a director during the Standstill Period, and at such time Vertex beneficially owns in the aggregate at least 3.0% of the Company’s then-outstanding Common Stock (subject to adjustment for stock splits, reclassifications, combinations and similar adjustments), Vertex shall have the ability to recommend a substitute person(s) for approval by the Nominating and Governance Committee of the Board (the “Governance Committee”) to fill the resulting vacancy, which person will (i) be independent of Vertex, (ii) qualify as “independent” pursuant to Nasdaq listing standards, and (iii) have relevant financial and business experience, all as determined by the Governance Committee.  The appointment of any such person to the Board will be subject to the approval of the Governance Committee after exercising its fiduciary duties in good faith, which approval shall not be unreasonably withheld (any such replacement nominee appointed in accordance with the terms of this Section 1(b)(6) will be referred to herein as the “Replacement Director”).  In the event the Governance Committee does not accept the Replacement Director recommended by Vertex, the Parties shall continue to follow the procedures of this Section 1(b)(6) until a Replacement Director is elected to the Board.  Upon the acceptance of a Replacement Director nominee by the Governance Committee, the Board will appoint such Replacement Director to the Board (or, if prior to the 2015 Annual Meeting, include such Replacement Director in the Company’s recommended slate of director candidates to be elected to the Board at the 2015 Annual Meeting) no later than five business days after the Governance Committee’s recommendation of such Replacement Director.

2

(c)           At the 2015 Annual Meeting, Vertex will appear in person or by proxy and vote all shares of Common Stock beneficially owned by it (i) in favor of all of the Company’s recommended nominees for election to the Board; (ii) against any director candidates not recommended by the Board; and (iii) in accordance with the Board’s recommendation with respect to the Company’s “say-on-pay” proposal, the Company’s proposal to amend the 2012 Equity Incentive Plan and the Company’s proposal to ratify the appointment of its registered public accounting firm unless, as it relates solely to the Company’s “say-on-pay” or Equity Incentive Plan proposal, respectively, Institutional Shareholder Services Inc. recommends otherwise.

(d)           Vertex acknowledges that all members of the Board, including the New 2015 Nominees (and any Replacement Director), are required to (i) comply with all policies, procedures, processes, codes, rules, standards and guidelines applicable to Board members, including the Company’s code of business conduct and ethics, securities trading policies, director confidentiality policies, and corporate governance guidelines, (ii) preserve the confidentiality of Company business and information, including discussions of matters considered in meetings of the Board or Board committees, (iii) complete the Company’s customary director & officer questionnaire and other reasonable and customary director onboarding documentation and procedures required by the Company in connection with the election or appointment of Board members (which the Company acknowledges has been done with respect to the questionnaire and representation and agreement previously provided to the Company on behalf of the New 2015 Nominees), and (iv) consent to be named as a nominee in the Company’s proxy statement and to serve as a director if elected.  Vertex shall provide the Company with such information concerning Vertex as is required to be disclosed under applicable law or stock exchange regulations, in each case as promptly as necessary to enable timely filing of the Company’s proxy statement.  Other than with respect to the indemnification agreements previously disclosed to the Company with respect to the New 2015 Nominees (which indemnification agreements Vertex represents and warrants it has provided in full to the Company prior to the date hereof), Vertex has not and will not enter into any monetary or other arrangements with any of the Company’s directors or director nominees.

2.             Standstill.   Vertex agrees that, from the date of this Agreement until the earlier of (i) the date that is fifteen (15) business days prior to the deadline for the submission of stockholder director nominations for the 2016 annual meeting of stockholders (the “2016 Annual Meeting”) pursuant to the Company’s bylaws or (ii) the date that is 100 calendar days prior to the one-year anniversary of the 2015 Annual Meeting (the “Standstill Period”), neither it nor any of its Affiliates or Associates will, and it will cause each of its Affiliates and Associates not to, directly or indirectly, in any manner (whether through third parties or otherwise):

3

(b)           seek or encourage any person to submit nominations in furtherance of a “contested solicitation” for the election 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 (including pursuing or encouraging any “withhold” or similar campaign), or otherwise seek to advise, influence or control the management (or any change thereof), governance, policies, business or affairs of the Company; provided, however, that if, at the beginning of the Search Period (as defined below), Vertex beneficially owns in the aggregate at least 3.0% of the Company’s then-outstanding Common Stock (subject to adjustment for stock splits, reclassifications, combinations and similar adjustments), Vertex may, beginning no earlier than January 1, 2016 (the “Search Period”), to the extent it reasonably determines necessary, privately identify potential director candidates in connection with the 2016 Annual Meeting on a confidential basis and without contacting any shareholder (or any other person other than the candidates themselves) regarding potential director candidates or regarding Vertex’s interest in or intent to identify director candidates (it being understood that Vertex may use a third-party director search firm to facilitate identification of potential candidates, but shall not disclose the Company’s name to such third-party director search firm); provided, further, that Vertex shall require each potential director candidate to enter into a confidentiality agreement prior to identifying the Company or engaging in any substantive discussions regarding the Company with any such potential director candidate and, provided, further, that Vertex shall continue to abide by all of the other provisions of this Section 2 and Section 3 hereof during the Search Period;

(c)           seek, alone or in concert with others, representation on the Board or other change in the composition of the Board, including through submitting any director nominations or participating in any “stockholder access” or “proxy access” regime that may become applicable to the Company;

(d)           seek to advise, encourage, support or influence any person with respect to the voting, giving or withholding of any proxy, consent, or other authority with respect to the securities of the Company (except such advice, encouragement, support or influence that is consistent with the Company’s recommendations on such matters) or the acquisition or disposition of any such securities;

(e)           (1) make any proposal (binding or non-binding) for consideration by stockholders at any annual or special meeting of stockholders of the Company or participate in any proposal made by any third party, (2) conduct a referendum of stockholders, (3) make a request for any stockholder list materials or any books and records of the Company or any of the Company’s Affiliates or Associates whether pursuant to Section 220 of the DGCL or otherwise or (4) (i) make any offer, recommendation, plan, purpose or proposal (with or without conditions) or, subject to the proviso in Section 3 hereof, public comment with respect to any share repurchase, dividend, self-tender or other change in capitalization, merger, acquisition, recapitalization, restructuring, disposition or other business combination or extraordinary transaction in the case of any of the foregoing involving the Company or any of the Company’s Affiliates or Associates, or any subsidiary, business or division of the foregoing, or (ii) make any offer, recommendation, plan, proposal or public comment with respect to any change in the management or material change in the business of the Company, or, in the case of any of the foregoing clauses (1) – (4), encourage, initiate or support any other third party in any such activity;

4

(f)           form, join or in any way participate in any partnership, limited partnership, syndicate or other group, including any “group” within the meaning of Section 13(d) of the Exchange Act, with respect to the Common Stock (other than a “group” that includes all or some of the entities identified on Exhibit A, but does not include any other entities not identified on Exhibit A as of the date hereof); provided, however, that a controlled Affiliate of Vertex may join such “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;

(i)           take any action that would, or would reasonably be expected to, require Vertex or the Company to make a public announcement or disclosure regarding any of the types of the matters addressed in this Section 2;

(j)           disclose that Vertex voted contrary to the recommendation of the Board on any matter other than as permitted by the proviso to Section 3 hereof;

(k)           enter into any discussions, negotiations, arrangements or understandings with any third party with respect to the matters set forth in this Section 2 or take or seek to take, or cause or seek to cause, or solicit others to take, any action inconsistent with this Section 2; or

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