ITEM 1.       SECURITY AND ISSUER

     This Amendment No. 6 (the "Amendment") amends the statement on Schedule 13D
filed on January 13, 2010 (the "Original Schedule 13D", as amended hereby and by
Amendment No. 1 filed on March 3, 2010, Amendment No. 2 filed on March 16, 2010,
Amendment  No. 3 filed on March 19, 2010,  Amendment No. 4 filed on May 11, 2010
and Amendment No. 5 filed on May, 18, 2010, the "Schedule 13D") with  respect to
the common stock,  no par value (the "Old Common Stock"),  of GSI  Group Inc., a
company  continued and existing under the laws of the Province of New Brunswick,
Canada (the "Issuer"). On the Effective Date (as defined below), all outstanding
shares of Old Common Stock were cancelled and an equivalent number of new shares
of common stock, no par value (the "Common  Stock"),  were issued to the holders
thereof.  This  Amendment  relates to the Common Stock.  Capitalized  terms used
herein and not otherwise  defined in this  Amendment have the meanings set forth
in the Schedule 13D. This  Amendment  amends Items 3, 4, 5, 6 and 7 as set forth
below.  This is the final  amendment  to the Schedule 13D and an exit filing for
the Reporting Person.

ITEM 3.       SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

Item 3 of the Schedule 13D is hereby amended and restated as follows:

     In connection with the bankruptcy of the Issuer Parties as described in the
Issuer's  current report on Form 8-K filed on July 23, 2010 (the "Issuer's Form
8-K"), and pursuant to the Fourth Modified Plan of Reorganization  under Chapter
11 of the Bankruptcy  Code, as confirmed by the United States  Bankruptcy  Court
for the  District  of  Delaware  (the  "Bankruptcy  Court") on May 27, 2010 (the
"Plan"), as of July 23, 2010 (the "Effective Date"), TCP II (a) received 392,666
shares of Common Stock in exchange for 418,464  shares of Old Common Stock,  (b)
received  198,413  shares of Common  Stock in exchange for its pro rata share of
$5,000,000  in principal  amount of Notes in  connection  with the  Supplemental
Equity Exchange (reflecting an effective conversion price of $1.80 a share), (c)
exchanged  $1,621,622 in principal  amount of Notes for 900,901 shares of Common
Stock at a price of $1.80 per share pursuant to the Backstop Commitment, and (d)
purchased  409,550 shares of Common Stock at a purchase price of $1.80 per share
in the Rights  Offering  (which purchase price was paid with $190.00 in cash and
by delivering to the Issuer $737,000 in principal amount of Notes).

ITEM 4.       PURPOSE OF TRANSACTION

Item 4 of the Schedule 13D is hereby amended and supplemented by the addition of
the following:

     As previously  disclosed,  on November 20, 2009,  the Issuer  Parties filed
voluntary  petitions in the Bankruptcy  Court for relief under Chapter 11 of the
Bankruptcy  Code. On May 24, 2010,  the Issuer Parties filed with the Bankruptcy
Court the Fourth Modified Plan of Reorganization,  as subsequently  modified. On
May 27, 2010, the Bankruptcy Court entered an order confirming the Plan.

     On the Effective Date, the Issuer Parties consummated their  reorganization
through a series of  transactions  contemplated  by the Plan and the Plan became
effective  pursuant to its terms. Under the Plan, TCP II received (i) $6,935,000
in principal amount of New Senior Secured Notes,  (ii) its pro rata share of the
Cash  Payment,  (iii) its pro rata  share of the cash  proceeds  from the Rights
Offering,  (iv)  payment of all accrued but unpaid  interest due under its Notes
through the Effective Date and (v) its pro rata share of the Supplemental Equity
Exchange.  In addition,  in connection with the Backstop  Commitment  previously
disclosed,  TCP II exchanged  $1,621,622  in  principal  amount of its Notes for
900,901 shares of Common Stock at a price of $1.80 per share. As a holder of Old
Common Stock  immediately  prior to the Effective Date, TCP II received  392,666
shares of Common Stock in exchange for its 418,464  shares of Old Common  Stock,
which  amount of Common  Stock  represents  93.835%  of the shares of Old Common
Stock held by TCP II immediately  prior to the Effective  Date.  Pursuant to the
Plan,  the  holders  of Old Common  Stock  received a number of shares of Common
Stock equal to 93.835% of the number of shares of Old Common  Stock held by them
immediately  preceding  the  Effective  Date and the  Issuer  placed a number of
shares of Common Stock equal to 6.165% of the aggregate  number of shares of Old
Common Stock outstanding  immediately preceding the Effective Date (the "Reserve
Shares") in reserve  subject to the resolution of a certain  pending  litigation
against the Issuer unrelated to the Chapter 11 cases of the Issuer Parties.  The
Reserve  Shares  are being  held in escrow  and the  escrow  agent will vote all
Reserve Shares proportionally in the same manner as the Common Shares are voted.






----------------------------                        -------------------------
CUSIP No.  36191C106            SCHEDULE 13D/A        Page 7 of 11 Pages

----------------------------                        -------------------------

On the Effective Date, TCP II also received its pro-rata portion of the backstop
commitment  fee  previously  disclosed in the Schedule 13D for its commitment to
backstop the Rights Offering, which aggregate fee for all Consenting Noteholders
was equal to 5% of the backstop commitment amount.

     TCP II also  participated  in the Rights Offering as a holder of Old Common
Stock. In the Rights Offering,  TCP II purchased  409,550 shares of Common Stock
at a  purchase  price of $1.80 per  share  (which  purchase  price was paid with
$190.00 in cash and by delivering to the Issuer $737,000 in principal  amount of
Notes).

     The New Senior Secured Notes were issued pursuant to that certain Indenture
for the New Senior Secured Notes among the Subsidiary, as issuer, the Guarantors
listed on the signature pages thereto, including the Issuer, and The Bank of New
York Mellon Trust  Company,  N.A., a national  banking  association,  as trustee
("Trustee")  for the holders  ("Holders")  of the New Senior  Secured Notes (the
"Indenture").  The  Subsidiary,  the  Issuer and the other  Guarantors,  and the
Trustee  (as  collateral  agent)  also  entered  into a  Security  Agreement  in
connection  with the  Indenture  (the  "Security  Agreement").  Pursuant  to the
Security Agreement, the Subsidiary, the Issuer and the other Guarantors, and the
Trustee (as collateral agent) entered into other security  documents,  including
certain mortgages and pledge agreements,  to grant to the Trustee (as collateral
agent) for the  benefit of the Holders a security  interest in and general  lien
upon  substantially all assets and properties,  real and personal,  now owned or
after acquired by the Issuer and the Subsidiary,  as applicable, as security for
all  obligations,  liabilities and  indebtedness of the Subsidiary under the New
Senior  Secured  Notes.  The  Indenture  and Security  Agreement are included as
Exhibits  4.1  and  10.1   respectively  to  the  Issuer's  Form  8-K,  and  are
incorporated herein by reference.

     The Plan provided,  among other things, that, as of the Effective Date, the
board of directors of the Issuer is set at seven members. The Plan provided that
two members would be selected by the Required Noteholders,  two members would be
selected  by the  Equity  Committee,  one  member  would be  selected  by mutual
agreement of the Required Noteholders and the Equity Committee, one member would
be selected by the previous board of directors of the Issuer from the members of
the  previous  board of  directors  of the Issuer,  and the Chief  Restructuring
Officer of the Issuer  would serve as a member of the board  (collectively,  the
"Initial  Board  Members").  Both the Plan and an  amendment  to the articles of
reorganization of the Issuer in effect as of the Effective Date provide that the
Initial Board Members may not be removed  during the period of one year from the
Effective  Date  without (i) the  approval of the person or persons by whom they
were selected,  or (ii) the approval of the New Brunswick Court of Queen's Bench
based upon a finding of cause.

     As  previously  disclosed,  the Plan  provides  that  three  holders of the
largest principal amount of Notes, may opt to have board observer rights subject
to reasonable restrictions.

----------------------------                        -------------------------

     Pursuant to the Plan,  on the  Effective  Date,  the Issuer  entered into a
registration  rights agreement (the  "Registration  Rights Agreement") with each
Consenting  Noteholder,  including TCP II. Pursuant to the  Registration  Rights
Agreement,  the  Issuer  agreed to  register  the resale of the shares of Common
Stock  issued  to such  holders  in  accordance  with  the  requirements  of the
Securities  Exchange  Act of  1933,  as  amended  (the  "Securities  Act").  The
Registration  Rights  Agreement  provides  that,  at any time from and after the
Effective Date,  holders party thereto  collectively  owning at least 30% of the
Registrable  Securities (as defined in the Registration  Rights  Agreement) have
the  right to  require  the  Issuer to effect  certain  underwritten  registered
offerings of such holders' Common Stock issued pursuant to the Plan  (including,
without limitation, those shares of Common Stock issued pursuant to the Backstop
Commitment),  on the terms and conditions set forth in the  Registration  Rights
Agreement. Holders of the Common Stock entitled to demand such registrations are
entitled  to request an  aggregate  of two (2)  underwritten  offerings  (which,
individually,  must  include an amount of Common Stock to be  registered  and/or
sold by such holders in excess of $5 million). In addition, holders party to the
Registration  Rights  Agreement  are entitled to request an unlimited  number of
piggyback  registrations.  The  above  summary  of  the  material  terms  of the
Registration  Rights  Agreement does not purport to be complete and is qualified
in its entirety by reference to the text of the Registration Rights Agreement, a
copy of which is  included  as  Exhibit 4.2 to the  Issuer's  Form  8-K,  and is
incorporated by reference herein.

     As a result of the consummation of the Restructuring  under the Plan on the
Effective Date,  there is no longer any argument that the Reporting  Persons may
be deemed to be  members  of a "group"  for  purposes  of  Section  13(d) of the
Securities  Exchange  Act of 1934  with  any of the  other  Jointly  Represented
Noteholders.  The Reporting Persons expressly disaffirm  membership in any group
with the other Jointly  Represented  Noteholders with regard to the Common Stock
at any time.

ITEM 5.       INTEREST IN SECURITIES OF THE ISSUER

Item 5 of the Schedule 13D is hereby amended and restated as follows:
