 Re: Termination of Employment 
 Dear David: 

This letter agreement (the “Letter Agreement”) sets forth the understanding between you and GSI Group, Inc., a company
organized under the laws of the Province of New Brunswick, Canada (together with its subsidiaries and affiliates, the “Company”), regarding your termination of employment with the Company and is entered into on the date set forth on
the signature page hereto. 
 1. Your last day of active employment with the Company shall be September 28, 2012 (or such
other date as mutually agreed by the parties hereto) (the “Termination Date”). At the Company’s request, effective as of the Termination Date, you hereby agree to resign as an officer and/or director of the Company and any of
the Company’s subsidiaries, affiliates, joint ventures and other related entities (including, without limitation, the Company’s Synrad, Inc., Continuum Electro-Optics, Inc., Quantronix Corp., JK Laser, Control Laser Corp. and Baublys
Control Laser businesses). On the Termination Date, the Company shall pay you (a) all earned but unpaid base salary up to and through the Termination Date, and (b) all accrued but unused vacation up to and through the Termination Date. The
Company also will reimburse you for all appropriately documented business expenses incurred prior to the Termination Date in accordance with the Company’s policy; provided that you submit all necessary or appropriate documentation of any
such expenses within ten (10) days of the Termination Date. 
 2. Subject to your execution and non-revocation of the
Release of Claims Agreement attached hereto as Exhibit A (the “Release”) at such time as is described in this Section 2, you shall be entitled to: 
 (a) Continued payment of your base salary, at the rate in effect immediately prior to the Termination Date, during the period beginning on the Termination Date and ending on the first anniversary of the
Termination Date (such payment, the “Severance Payment” and such period, the “Severance Period”), payable in equal installments during the Severance Period in accordance with the Company’s customary payroll
practices; 







 (b) A cash payment in an aggregate amount equal to $130,000, payable in two equal
installments at the same times as you would have been entitled to receive such installments as a bonus in respect of the second half of 2012 and first half of 2013 pursuant to the terms of the Senior Management Incentive Plan (or comparable plan for
2013) (which are expected to be in March 2013 and August 2013), but in no event prior to January 1, 2013 or later than December 31, 2013; and 
 (c) If you elect to continue medical coverage under the Company’s group health plan in accordance with COBRA, continued participation in the Company’s group health plan in which you were
participating as of the Termination Date, with the then-current Company premium subsidy applicable to employees, during period beginning on the Termination Date and ending on the earlier of (i) the last day of the Severance Period, and
(ii) the date on which you first become eligible for medical coverage from a new employer or service recipient. The COBRA health continuation period under Section 4980B of the Internal Revenue Code of 1986, as amended, shall run
concurrently with the period of continued medical coverage following the Termination Date set forth in this Section 2(c). 
 Notwithstanding anything to the contrary in this Letter Agreement or the Release, (x) you shall not be entitled to any payments or benefits under this Section 2 unless and until you execute the
Release on or prior to the 21st day following the date you
receive the Release (the “Release Expiration Date”) and do not revoke your execution of the Release thereafter (and the applicable revocation period has expired) and (y) to the extent any payments or benefits due under the
Letter Agreement are not paid or provided when due as result of the immediately preceding subsection (x), such payments and benefits shall be paid or provided in a lump sum on the first payroll date to occur on or after the thirtieth (30th) day
following the Termination Date. 
 3. In addition to the post-termination benefits described in Section 2, and
notwithstanding anything to the contrary in those certain Restricted Stock Unit Grant Notices and Restricted Stock Unit Award Agreements between you and the Company, dated March 31, 2011 and March 8, 2012 (collectively, the “RSU
Agreements”), (a) as of the Termination Date, 10,000 unvested restricted stock units granted under the RSU Agreements (the “Unvested RSUs”) shall remain outstanding and unvested, (b) subject to your execution of
the Release on or prior to the Release Expiration Date and the lapse of any revocation period related thereto, the Unvested RSUs shall become vested on the thirtieth (30th) day following the Termination Date, and (c) to the extent you do
not execute the Release on or prior to the Release Expiration Date or timely revoke the execution of such Release thereafter, the Unvested RSUs shall be automatically forfeited by you on the thirtieth (30th) day following the Termination Date
without payment of any consideration by the Company, and you (or your beneficiary or personal representative, as the case may be) shall have no further rights with respect to the Unvested RSUs. For the avoidance of doubt, all unvested restricted
stock units granted under the RSU Agreements other than the Unvested RSUs shall be automatically forfeited, terminated and canceled as of the Termination Date pursuant to terms of the RSU Agreements. 

4. You agree not to disparage the Company, any of its products or practices, or any of its directors, officers, agents, representatives
or affiliates, either orally or in writing, at any time; provided that you may confer in confidence with your legal representatives and make truthful statements as required by law. The Company agrees that, upon the termination of your


  
 2 








 
employment, it shall advise its current directors and officers not to disparage you, either orally or in writing, at any time; provided that such persons may confer in confidence with the
Company’s and their legal representatives and make truthful statements as required by law. In addition, you acknowledge and agree that you currently are and, on and after Termination Date, shall remain, subject to all restrictive covenants set
forth in the RSU Agreements. 
 5. Notwithstanding anything to the contrary in this Letter Agreement, in the event that you
violate any of the restrictive covenants set forth or described in Section 4 (including, without limitation, those set forth in the RSU Agreements), (a) the Company shall no longer be required to provide any payments or benefits under this
Letter Agreement and (b) you shall pay the Company an amount equal to the sum of (i) all payments and benefits provided in this Letter Agreement prior to such violation (including, without limitation, the applicable portion of the
Severance Payment) and (ii) the greater of (A) the fair market value of a number of shares of common stock of the Company equal to the number of Unvested RSUs on the Termination Date or (B) the fair market value of a number of shares
of common stock of the Company equal to the number of Unvested RSUs on the date on which you first violate such restrictive covenants. 
 6. You agree to sign and be bound by the Release, which shall be considered an integral part of this Letter Agreement. 
 7. In order to effectuate the foregoing, you agree to execute any additional documents as may be reasonably requested from time to time by the Company. Except as set forth in this Letter Agreement and the
Release, the RSU Agreements will remain in full force and effect. 
 8. Because your employment with the Company was terminated
involuntarily for other than gross misconduct, the Company acknowledges and agrees that it will not contest your eligibility for unemployment compensation.
