SECURITY AND ISSUER This Amendment No. 1 (the "Amendment") amends the statement on Schedule 13D filed on July 2, 2009 (the "Original Schedule 13D", as amended, the "Schedule 13D") with respect to the common stock, no par value (the "Common Stock"), of GSI Group Inc., a company continued and existing under the laws of the Province of New Brunswick, Canada (the "Issuer"). Capitalized terms used herein and not otherwise defined in this Amendment have the meanings set forth in the Original Schedule 13D. This Amendment amends Items 4, 5(c), 6 and 7 as set forth below. ITEM 4. PURPOSE OF TRANSACTION Item 4 of the Schedule 13D is hereby amended and supplemented by the addition of the following: On November 19, 2009, Liberty Harbor and certain of the other Noteholders (the "Consenting Noteholders") entered into a Noteholder Restructuring Plan Support Agreement (the "Plan Support Agreement") with the Issuer, the Subsidiary and certain of their subsidiaries and affiliates (together, the "Issuer Parties"), under which the parties thereto agreed to the terms of a restructuring of the Notes pursuant to a chapter 11 plan of reorganization, the terms of which are substantially similar to those set forth in the Term Sheet. The commitment to support the restructuring is contingent, among other things, upon receipt of a bankruptcy court approved Disclosure Statement (as defined in the Plan Support Agreement) and other solicitation materials in support of the Plan. Pursuant to the Plan Support Agreement, the Noteholders party thereto agreed, among other things subject to certain exceptions, (i) to vote all claims or shares it holds or asserts against the Issuer Parties in favor of the Plan (as defined in the Plan Support Agreement), (ii) not to object to confirmation of the Plan or object to or otherwise commence any proceeding to oppose or alter the Plan or support an alternative plan, and (iii) not to withdraw, change or revoke its vote with respect to the Plan, except as otherwise provided in the Plan Support Agreement, and (iv) except as otherwise permitted in the Plan Support Agreement, not to take any other action that would materially prevent or delay the consummation of the restructuring contemplated by the Plan Support Agreement. The Plan Support Agreement is subject to termination upon the occurrence of certain events, including, without limitation, (i) at the option of 66 2/3% of Consenting Noteholders (the "Required Noteholders"), upon the failure of the Issuer Parties to take certain actions by specified milestone dates, (ii) at the option of the Issuer Parties or the Required Noteholders, if the bankruptcy court grants relief that is materially inconsistent with the Plan Support Agreement or the Plan or (iii) at the option of the Required Noteholders, upon the occurrence of a Material Adverse Change (as defined in the Plan Support Agreement). This description of the Plan Support Agreement is a summary only and is qualified in its entirety by reference to the Plan Support Agreement, a copy of which is referenced as Exhibit 11 hereto (which incorporates by reference Exhibit 10.1 of the Current Report on Form 8-K filed by the Issuer on November 20, 2009) and is incorporated herein by reference. ---------------------------- ---------------------------- CUSIP No. 36229U102 SCHEDULE 13D/A Page 6 of 7 Pages ---------------------------- ---------------------------- As more fully described in the Plan, under the Plan the Notes will be exchanged for, among other things, New Senior Secured Notes (as defined in the Plan) and common stock of the reorganized Issuer. This description of the Plan is a summary only and is qualified in its entirety by reference to the Plan, a copy of which was filed as Exhibit A of Exhibit 10.1 of the Current Report on Form 8-K filed by the Issuer on November 20, 2009. In addition, the 10th paragraph of Item 4 of the Schedule 13D is hereby amended to add the following: The Reporting Persons and certain of the other Noteholders (the "Jointly Represented Noteholders") have jointly retained counsel in connection with their respective investments in the Notes to negotiate on behalf of the Jointly Represented Noteholders in connection with the restructuring of the Notes. Each Jointly Represented Noteholder will make an independent decision regarding any proposal to or from the Issuer relating to its investment in the Notes. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER Item 5(c) of the Schedule 13D is hereby amended and restated as follows: (c) No transactions in the Common Stock were effected by the Reporting Persons or, to the knowledge of any of the Reporting Persons, any of the persons listed on Schedule I-A or Schedule I-B hereto, during the sixty day period from September 20, 2009 through November 19, 2009. ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER Item 6 of the Schedule 13D is hereby amended and supplemented by the addition of the following: As described in Item 4 above, on November 19, 2009, the Consenting Noteholders entered into the Plan Support Agreement with the Issuer Parties, under which the parties thereto agreed to the terms of a restructuring of the Notes pursuant to a chapter 11 plan of reorganization a copy of which is referenced as Exhibit 11 hereto (which incorporates by reference Exhibit 10.1 of the Current Report on Form 8-K filed by the Issuer on November 20, 2009) and is incorporated herein by reference.

Noteholder Restructuring Plan Support Agreement, dated as of November 19, 2009, by and among the Consenting Noteholders and the Issuer Parties (incorporated by reference to Exhibit 10.1 to the Current Report on Form 8-K filed by the Issuer on November 20, 2009). ---------------------------- ---------------------------- CUSIP No. 36229U102 SCHEDULE 13D Page 7 of 7 Pages ---------------------------- ---------------------------- Signature After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
