ITEM 3.       SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

     The shares of Common Stock reported herein were acquired through a cashless
exercise of the Warrants (as defined in Item 4 below)  issued to Liberty  Harbor
(the  "Original LH  Warrants").  The Original LH Warrants were issued to Liberty
Harbor in connection with its purchase of the Notes (as defined in Item 4 below)
pursuant to the Securities  Purchase Agreement (as defined in Item 4 below) (the
Notes so purchased, the "Original LH Notes"). The Original LH Notes and Original
LH Warrants  were acquired with Liberty  Harbor's  investment  funds in accounts
under  management.  A total of  $55,000,000  was paid to acquire the Original LH
Notes and the Original LH Warrants.

     None of the  individuals  listed on Schedule I-A or Schedule I-B hereto has
contributed  any funds or other  consideration  towards the  acquisition  of the
shares  of  Common  Stock  reported  herein  except  insofar  as they  may  have
partnership  or member  interests in any of the Reporting  Persons and have made
capital contributions to any of the Reporting Persons, as the case may be.

ITEM 4.       PURPOSE OF TRANSACTION

     The shares of Common  Stock  reported  herein are held  directly by Liberty
Harbor.  The  shares of Common  Stock  reported  herein  were  acquired  upon an
automatic cashless exercise of the Original LH Warrants for investment purposes,
in the ordinary course of the Reporting Person's business, because the Reporting
Persons  believed they  represented an attractive  investment  opportunity.  The
Reporting  Persons may be deemed to beneficially  own 1,534,369 shares of Common
Stock, representing approximately 3.2% of the shares of Common Stock outstanding
based on 47,591,899  shares of Common Stock outstanding as set forth in the Rule
424(b)(3) Prospectus filed by the Issuer on October 23, 2008.

     On  July  9,  2008,  pursuant  to  a  Securities  Purchase  Agreement  (the
"Securities Purchase Agreement"), by and among the Issuer, GSI Group Corporation
(the "Subsidiary"),  Liberty Harbor and certain other parties thereto (together,
the "Lenders"),  Liberty Harbor  purchased (x) 11% Senior Notes (the "Notes") of
the Subsidiary issued pursuant to that certain Indenture, dated as of August 20,
2008 (the "Indenture"), between the Subsidiary, the Issuer and Eagle Acquisition
Corporation, as guarantors, and The Bank of New York Mellon Trust Company, N.A.,
as trustee (in such capacity, the "Trustee") and (y) Warrants to Purchase Common
Stock (the "Warrants") pursuant to the Warrant Agreement, dated August 20, 2008,
by and among GSI Group Inc. and the Lenders (the "Warrant Agreement").

     Concurrently  with the  closing  of the  transactions  contemplated  by the
Securities  Purchase  Agreement,  the  Issuer  and the  Lenders  entered  into a
Registration Rights Agreement (the "Registration Rights Agreement"), pursuant to
which the Issuer agreed to provide certain  registration  rights with respect to
the shares of Common Stock  issuable  upon  exercise of the  Warrants  under the
Securities  Act of  1933,  as  amended  (the  "1933  Act")  and  the  rules  and
regulations promulgated thereunder, and applicable state securities laws.

     The Securities  Purchase Agreement,  the Registration Right Agreement,  the
Indenture  and the Warrant,  copies of which are  referenced,  respectively,  as
Exhibits 2, 3, 4 and 5 hereto (which  incorporates by reference  Exhibit 10.1 of
the  Current  Report  on Form 8-K  filed by the  Issuer  on July 11,  2008,  and
Exhibits  10.3,  10.1 and 10.2 of the  Current  Report  on Form 8-K filed by the
Issuer on August 21, 2008) are each incorporated herein by reference.

     The Original LH Warrants were automatically exercised into 1,534,369 shares
of Common  Stock  pursuant to the terms of the Warrant  Agreement  on a cashless
basis at the time the registration statement filed by the Issuer pursuant to the
Registration  Rights  Agreement  was declared  effective by the  Securities  and
Exchange Commission (the "SEC").

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

     On December 3, 2008,  Liberty Harbor delivered a notice of default pursuant
to Section  6.01(4) of the Indenture to the Subsidiary  (the "Default  Notice"),
which set forth a default by the Subsidiary  pursuant to Section  4.02(a) of the
Indenture,  as a result of the Issuer's failure to (i) timely file its Quarterly
Report on Form 10-Q for the  quarterly  period  ended  September  26,  2008 (the
"September  2008 10-Q") with the SEC within the time  periods  specified  in the
SEC's rules and regulations,  (ii) furnish a copy of the same to the Trustee for
delivery to the Holders  (as  defined in the  Indenture)  of the Notes and (iii)
post the same on the Issuer's  website or otherwise  make the same  available to
the prospective  purchasers of the Notes. The Issuer has not filed the September
2008  10-Q to  date.  Subject  to the  Forbearance  Agreement  described  below,
beginning  60 days after the Default  Notice was  delivered  to the  Subsidiary,
Liberty  Harbor has had the  ability,  as a holder of  $70,000,000  in principal
amount  of  Notes,  to  exercise  its  right  to  accelerate  the   indebtedness
outstanding under the Indenture.

     On February 6, 2009,  the  Subsidiary  and Liberty  Harbor  entered  into a
Forbearance  Agreement  pursuant to which Liberty Harbor agreed to forebear from
taking any action or exercising any remedies under the Indenture  related to the
above mentioned Event of Default (the "Forbearance Agreement").  The Forbearance
Agreement terminated on February 27, 2009.

     The  Subsidiary and Liberty  Harbor have come to  preliminary,  non-binding
terms to be used to restructure  the debt  outstanding  under the Indenture (the
"Restructuring").  The proposed terms of the Restructuring were determined as of
June 22, 2009 to include the reduction of the amount of debt  outstanding  under
the Indenture to $95,000,000, the granting of a first priority lien with respect
to the  remaining  debt  outstanding  under the  Indenture,  the issuance to the
holders of Notes  (collectively,  the  "Noteholders")  of a  substantial  equity
interest in the Issuer in exchange for the reduction in debt (which interest, in
the aggregate,  would  represent up to 80% of the Issuer's equity on a pro forma
basis),  the transition to a board of directors that would be reflective of such
equity ownership, the deletion of certain restrictive covenants in the Indenture
and the  implementation of a new management stock and option incentive plan. The
complete  preliminary  terms of the Restructuring are set forth in a non-binding
term sheet (the "Term Sheet"), a copy of which is referenced as Exhibit 6 hereto
(which  incorporates by reference Exhibit 99.1 of the Current Report on Form 8-K
filed by the Issuer on June 30, 2009) which is incorporated herein by reference.

     Upon information and belief,  certain of the other  Noteholders have agreed
with the Subsidiary to the proposed terms of the  Restructuring set forth in the
Term Sheet.

     The Reporting Persons,  through Liberty Harbor, may act in concert with the
other  Noteholders  solely  in their  capacity  as  creditors  of the  Issuer in
connection with the  Restructuring.  By virtue of such actions,  the Noteholders
may be deemed  to form a group  within  the  meaning  of Rule  13d-5 of the Act,
however the Reporting Persons expressly  disaffirm the existence of a group with
regard to the  Common  Stock.  The  Reporting  Persons  do not have any plans or
proposals to exercise any remedy available to the Reporting Persons by virtue of
the Reporting Persons' beneficial ownership of equity securities of the Issuer.

     Although the Reporting Persons do not have any specific plan or proposal to
acquire or dispose of shares of Common Stock other than as set forth above,  the
Reporting  Persons at any time and from time to time may (i) acquire  additional
shares or  securities  of the  Issuer,  (ii)  dispose  of any or all of  Liberty
Harbor's  securities  of the  Issuer,  (iii)  enter  into  privately  negotiated
derivative  transactions with  institutional  counterparties to hedge the market
risk of some or all of  Liberty  Harbor's  positions  in the  securities  of the
Issuer, depending upon the factors

described below and/or other investment  considerations or (iv) exercise Liberty
Harbor's  rights,  if  any,  as a  holder  of the  Notes  in  connection  with a
bankruptcy, restructuring or other case or proceeding of the Issuer.

     In  addition,  the  Reporting  Persons  intend to review  Liberty  Harbor's
investment  in the Issuer on a  continuing  basis and may seek to  influence  or
change the Issuer's operations or business development plans, business strategy,
management  or directors,  competitive  position,  capital  structure or capital
management policy, including, without limitation,  through potential discussions
with  management,  directors,  other  shareholders  and the  other  Noteholders,
existing or potential strategic partners or competitors of the Issuer,  industry
analysts,  investment  and financing  professionals  and/or other third parties.
Such matters and discussions may materially affect, and result in, the Reporting
Persons  modifying  Liberty  Harbor's  investment  in  the  Issuer,   exchanging
information with any of such persons pursuant to appropriate  confidentiality or
similar  agreements  or  otherwise,  working  together  with any of such persons
pursuant to joint  agreements  or otherwise,  proposing  changes in the Issuer's
operations,  governance,  capitalization  or strategic plans, or in proposing or
engaging in one or more other  actions set forth under  subsections  (a) through
(j) of Item 4 of Schedule 13D. Factors that may influence the Reporting Persons'
actions  include,  but are not limited to,  their view  regarding  the  Issuer's
operations,  business strategy,  prospects,  financial position and/or strategic
direction,  the outcome of the discussions and actions referenced herein,  price
levels  of the  Common  Stock  and  other  securities,  availability  of  funds,
subsequent  developments  affecting the Issuer,  other  investment  and business
opportunities  available to the Reporting Persons,  conditions in the securities
and debt market, general economic and industry conditions and other factors that
the Reporting Persons may deem relevant from time to time.

     Except as described herein,  the Reporting Persons do not have any plans or

the Reporting  Persons in accordance  with the Release,  and, in reliance on the
Release,  this filing does not include  information  regarding  GS Group and its

of the securities  beneficially owned by (i) any client accounts with respect to
