Bankruptcy Court for the District of Delaware (as it may have been or may be modified from time to time, the “Plan of Reorganization”) and the Equity Committee (as defined in the Plan of Reorganization) and its members, in their
capacity as members of the Equity Committee and as individual entities, and with respect to each of the foregoing entities, such entity’s current and former affiliates, predecessors, successors in interest, parent entities, subsidiaries,

professionals, in each case in their capacity as such (collectively, the “Company Releasees”), from any and all claims, demands, actions, liabilities and other claims for relief and remuneration whatsoever (other than claims,
demands, actions, liabilities and other claims for relief and remuneration arising out of Executive Releasing Parties’ ownership, whether individually or as trustee, of stock of the Company), whether known or unknown, from the beginning of the
world to the date Executive signs this Agreement, but otherwise including, without limitation, any claims arising out of or relating to Executive’s employment with and termination of employment from the Company, for wrongful discharge, for
breach of contract, for discrimination or retaliation under any federal, state or local fair employment practices laws, including, Title VII of the Civil Rights Act of 1964 (as amended by the Civil Rights Act of 1991), the Family and Medical Leave
Act, the Americans with Disabilities Act, the Age Discrimination in Employment Act, for defamation or other torts, for wages, bonuses, incentive compensation, stock, stock options, vacation pay or any other compensation or benefit and any claims
under any tort or contract (express or implied) theory, and any of the claims, matters and issues which could have been asserted by the Executive Releasing Parties against the Company Releasees in any legal, administrative or other proceeding in any
jurisdiction. 
 (b) In exchange for the consideration described herein, the Company and its present and past subsidiaries and
affiliates, including, without limitation, MES International, Inc., GSI Group Inc. and GSI Group Corporation and its and their respective successors and assigns, and the present and past shareholders, officers, directors, employees, agents and
representatives of each of the foregoing (collectively, the “Company Releasing Parties”), hereby releases and discharges, Executive, his agents, 

 

 3 








 
legal representatives, assigns, heirs, distributes, devisees, legatees, administrators, personal representatives and executors (collectively, the “Executive Releasees”), from any
and all claims, demands, actions, liabilities and other claims for relief and remuneration whatsoever, whether known or unknown, from the beginning of the world to the date Company signs this Agreement, but otherwise including, without limitation,
any claims arising out of or relating to Executive’s employment with the Company, for breach of contract, for defamation or other torts, for wages, bonuses, incentive compensation, stock, stock options, vacation pay or any other compensation or
benefit and any claims under any tort or contract (express or implied) theory, and any of the claims, matters and issues which could have been asserted by the Company Releasing Parties against the Executive Releasees in any legal, administrative or
other proceeding in any jurisdiction. Nothing in this Section 3(b) shall adversely affect or impair any release of the Executive as set forth in the Plan of Reorganization. 

(c) Nothing in Section 3(a) shall release Executive’s right to indemnification if Executive is made a party, or is threatened
to be made a party, to any action, suit or proceeding, whether civil, criminal, administrative or investigative (a “Proceeding”), by reason of the fact that he is or was a director, officer or employee of the Company or any
Subsidiary or is or was serving at the request of the Company or any Subsidiary as a director, officer, member, employee or agent to another corporation, partnership, joint venture, trust or other enterprise, including service with respect to
employee benefit plans, whether or not the basis of such Proceeding is Executive’s alleged action in an official capacity while serving as a director, officer, member, employee or agent, Executive shall be indemnified and held harmless by the
Company to the fullest extent legally permitted or authorized by the Company’s certificate of incorporation or bylaws or resolutions of the Company’s Board or, if greater, by the laws of the Province of New Brunswick, Canada against all
cost, expense liability and loss (including, without limitation, attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by Executive in connection
therewith, and such indemnification shall continue as to Executive even if he has ceased to be a director, member, officer, employee or agent of the Company or other entity and shall inure to the benefit of Executive’s heirs, executors and
administrators. The Company shall advance to Executive all reasonable costs and expenses to be incurred by him in connection with a Proceeding within 30 days after receipt by the Company of a written request for such advance. Such request shall
include a written undertaking by Executive to repay the amount of such advance if it shall ultimately be determined that he is not entitled to be indemnified against such costs and expenses within 30 days of receiving such determination. The
provisions of this Section 3(c) shall not be deemed exclusive of any other rights of indemnification to which Executive may be entitled or which may be granted to him, and shall be in addition to any rights of indemnification to which Executive
may be entitled under any policy of insurance. Consistent with the provisions of Section 81(1)(a) of the New Brunswick Business Corporations Act, such indemnification, including any advancement of defense costs will only be allowed if the
Executive acted honestly and in good faith with a view to the best interests of the Company. Prior to receiving any advancement of defense costs, the Executive will be required to execute an undertaking confirming that in the event such Executive is
found to have acted other than honestly or in good faith with a view to the best interests of the Company, such costs will be returned to the Company.

 (d) Neither the failure of the Company (including its Board, independent legal counsel or
stockholders) to have made a determination prior to the commencement of any proceeding concerning payment of amounts claimed by Executive under Section 3(c) above that indemnification of Executive is proper because he has met the applicable
standard of conduct, nor a determination by the Company (including its Board, independent legal counsel or stockholders) that Executive has not met such applicable standard of conduct, shall create a presumption that Executive has not met the
applicable standard of conduct. 
 (e) The Company agrees to the extent it maintains a directors and officers’ liability
insurance policy for its other executive officers that it shall continue to cover the Executive. 
 (f) The Company agrees that
it shall not modify the Plan of Reorganization in any way that would prevent the Executive from being one of the “Released Parties” under the Plan of Reorganization or result in the Executive receiving any less favorable treatment under
Section 6.20 or 6.21 of the current Fourth Modified Joint Chapter 11 Plan of Reorganization (or any similar provision of the Plan of Reorganization) as shall be provided to other “Released Parties” under the Fourth Modified Joint
Chapter 11 Plan of Reorganization. In addition, the Company agrees that it shall not modify the Fourth Modified Joint Chapter 11 Plan of Reorganization in any way that would provide any less favorable treatment with respect to the Executive’s
shares of the Company’s common stock than is provided to other holders of the Company’s common stock under the current Fourth Modified Joint Chapter 11 Plan of Reorganization. 

4. Transfer of Property. Executive will deliver to the Company all property (other than his BlackBerry), documents, or materials
in his possession or custody, of any nature belonging to the Company whether in original form or copies of any kind, including any trade secrets and proprietary information upon the Separation Date. The Executive agrees and covenants to promptly
assist the Company, as may be requested by the Company, to transfer ownership of any Company property or assets (other than his cellular telephone number) that currently is held in the name of the Executive personally or as an officer of the
Company, including, but not limited to, the execution of any transfer or assignment documents or of any other state or similar filings.

officer, director, partner, or majority shareholder of any entity that is not a Direct Competitor at the time Executive initially becomes employed or becomes a principal, agent, consultant, officer, director, partner, or majority shareholder of the
entity, future activities of such entity shall not result in a violation of this provision unless (x) such activities were contemplated by Executive at the time Executive initially became employed or becomes a principal, agent, consultant,
officer, director, partner, or less than ten percent shareholder of the entity or (y) Executive commences directly or indirectly to plan, oversee or manage the activities of an entity which becomes a Direct Competitor during the Second Year of
the Restriction Period, which activities are competitive with the activities of the Company or any Subsidiary.
